Technical Field
[0001] The present invention relates to a toilet deodorizing method, a toilet, and a toilet
deodorizing device. Specifically, the present invention relates to a method of deodorizing
an air including odor in a toilet main body of a toilet, a toilet including a deodorizing
device which deodorizes an air in a toilet main body, a toilet deodorizing device
including a deodorizing cartridge which is provided in a deodorizing flow channel
of the toilet and adsorbs an air in air flowing in the deodorizing flow channel, a
toilet including a deodorizing device which deodorizes an air generated in a toilet
bowl, a toilet having a deodorizing device, a toilet deodorizing device being attached
to a toilet main body, and a toilet in which the deodorizing device is provided.
Background Art
[0003] In the related art, there are toilets including a private part washing device for
washing a private part after defecation or a deodorizing device for suctioning and
deodorizing odors during defecation and after defecation.
[0004] For example, a private part washing device (private part washing unit) includes a
private part washing nozzle which moves forward/rearward, protrudes, and retracts
between the inner side of a toilet main body, and a cover case and a nozzle cover
through a nozzle opening portion in response to an operation or the like conducted
by means of a remote controller. The private part washing device is configured to
wash a private part as follows. The private part washing nozzle advances while pressing
and tilting a shutter which opens and closes the nozzle opening portion such that
the shutter is opened. Then, washing water is discharged from a tip end portion of
the private part washing nozzle which has advanced to the inner side of the toilet
main body.
[0005] For example, a deodorizing device (deodorizing unit) is provided as a unit integrated
with the private part washing device on an upper surface of a rear portion of the
toilet main body. The deodorizing device is configured to suction stagnant air in
the toilet main body through a suction port open toward the toilet main body, to perform
deodorization by eliminating and decomposing odorous components by using an adsorption-type
or decomposition-type deodorizing cartridge (deodorizing device), and to expel the
air to the outside (for example, refer to Patent Document 1).
[0006] Meanwhile, due to a positional relationship with the nozzle opening portion or the
like for causing the private part washing nozzle of the private part washing device
to protrude and retract, there is a certain degree of restriction on the size of the
suction port of the deodorizing device provided in the rear portion of the toilet
main body. Accordingly, there is a disadvantage, for example, a high-power fan is
required in order to suction stagnant air in the toilet main body.
[0007] On the other hand, the inventors of this application have invented a deodorizing
method and a deodorizing device, which are already in progress of patent application
(Japanese Patent Application No.
2014-086359). According to the invention, a discharge port and a suction port of air are provided
in a rear portion of a toilet main body. Air is discharged through the discharge port
such that the air laterally swirls along an inner side surface of a rim portion of
the toilet main body. The air which has swirled and returned is suctioned through
the suction port such that the air circulates. Then, deodorization is performed in
a circulation process.
[0008] According to the deodorizing method and the deodorizing device, an air flow is generated
above the toilet main body due to lateral swirling, so that stagnant air can be taken
into the suction port in a manner of being attracted. Therefore, in the deodorizing
method and the deodorizing device, deodorization can be efficiently performed without
using a high-power fan. Accordingly, it is possible to suppress an odor from rising
upward from the toilet main body and being diffused.
[0009] In the deodorizing method and the deodorizing device of the inventors of this application,
air is discharged onto the inner side surface of the toilet main body through the
discharge port, and a circulation flow laterally swirling along the rim portion is
formed. Therefore, in the deodorizing method and the deodorizing device, for example,
it is assumed that air on the inner side of a circulation flow is taken upward when
a user stands up from a toilet seat and an odor is diffused.
[0010] Next, in the related art, flushing-type toilets installed with a deodorizing device
which suctions and deodorizes an odor during defecation are known. As disclosed in
Patent Document 2, most of such toilet deodorizing devices are each provided as a
unit integrated with a private part washing device on an upper surface of a rear portion
of a toilet bowl, following the low silhouette trend of toilet. Such a deodorizing
device has a suction port open toward the toilet bowl, suctions stagnant air above
the toilet bowl, deodorizes an odor, and then expels the air to the outside through
a discharge port.
[0011] In the deodorizing device, the suction port and the discharge port open in the toilet
bowl are interlinked with each other through a deodorizing flow channel such as a
deodorizing duct. A deodorizing cartridge including a deodorizing catalyst and a deodorizing
fan are installed in the deodorizing flow channel.
[0012] When an odor is generated in the toilet bowl, the deodorizing device efficiently
deodorizes the odor by operating the deodorizing fan such that air in the toilet bowl
flows through the deodorizing flow channel through the suction port and circulates
while the deodorizing cartridge adsorbs the odor.
[0013] Incidentally, in recent years, miniaturization of private part washing devices has
been in progress, and miniaturization of deodorizing cartridges provided in a deodorizing
flow channel of a deodorizing device has also been in progress. Accordingly, due to
the dense mesh size of a deodorizing catalyst, resistance of an air flow passing through
the deodorizing catalyst increases and the air flow speed deteriorates, leading to
a flaw of deterioration of deodorizing efficiency.
[0014] In addition, in the deodorizing device, a suction port open in a toilet bowl and
a discharge port open toward the outside of the toilet bowl are interlinked with each
other through the deodorizing flow channel such as a deodorizing duct. The deodorizing
cartridge including the deodorizing catalyst and a deodorizing fan are installed in
the deodorizing flow channel.
[0015] When an odor is generated in the toilet bowl, the deodorizing device efficiently
deodorizes the odor by operating the deodorizing fan such that air in the toilet bowl
flows through the deodorizing flow channel through the suction port and circulates
while the deodorizing cartridge adsorbs the odor.
[0016] However, the suction port and the discharge port of the deodorizing device are installed
on an upper side of an opening of the toilet bowl. Therefore, both a discharging air
flow from the discharge port and a suctioning air flow to the suction port have significantly
inclined angles, and it is not possible to mention that a smooth circulation flow
channel can be formed between an air flow in the toilet bowl and the deodorizing device.
[0017] Next, in the related art, a toilet provided with a deodorizing device deodorizing
the inside of a toilet bowl is known (for example, refer to Patent Document 3 and
Patent Document 4). In addition, a toilet provided with a deodorizing device deodorizing
a water closet space is known.
[0018] For example, in the deodorizing device, an odor generated in the toilet bowl is deodorized
by using a deodorant, sterilizing ions are generated in the deodorized air, the deodorized
air having generated sterilizing ions is released in the toilet bowl or the water
closet space, and then the inside of the toilet bowl or the water closet space is
deodorized.
[0019] When both the deodorizing device deodorizing the inside of a toilet bowl and the
deodorizing device deodorizing a water closet space are provided in the toilet, there
is concern that an installation space for the devices increases and the structure
of the toilet becomes complicated. Therefore, it is desirable to deodorize the inside
of the toilet bowl and to deodorize the water closet space by using the same deodorizing
device.
[0020] However, in a case of deodorizing the water closet space by using the deodorizing
device deodorizing the inside of the toilet bowl, since the deodorizing device deodorizing
the inside of the toilet bowl is configured to discharge air for deodorization downward
to the inside of the toilet bowl, it is difficult to deodorize a position where a
user sits or a position where the user stands, above the toilet bowl.
[0021] Next, in the related art, in a duct (deodorizing flow channel) of a deodorizing device
for deodorizing an odor generated in a toilet bowl of a toilet main body, a dust collection
filter for collecting dust in air suctioned to the duct is provided on a suction port
side (for example, refer to Patent Document 5). Such a dust collection filter is configured
to be attachable and detachable with respect to the duct, so that the dust collection
filter can be taken out from the duct and can be cleaned.
[0022] In a case where the dust collection filter is attached and detached through the inside
of the toilet bowl, an attaching and detaching port of the dust collection filter
is provided open in the toilet bowl. Therefore, there are cases where a spray in the
toilet bowl enters a dust collection filter installation part through the attaching
and detaching port of the dust collection filter and the dust collection filter becomes
unclean due to the spray.

Solution to Problem
[0029] In order to achieve the objects described above, the present invention provides the
following means.
[0030] According to a first aspect of the present invention, a toilet deodorizing method
includes forming a lateral swirl flow of air laterally swirling along an inner surface
of a toilet main body and a traversal flow of air traversing an inside of the toilet
main body, by discharging air into the toilet main body of a toilet through a discharge
port and by suctioning air in the toilet main body through a suction port; and deodorizing
the air including an odor in the toilet main body by using a deodorizing device for
eliminating an odorous component of air which flows due to the lateral swirl flow
and the traversal flow and which is suctioned through the suction port.
[0031] According to the toilet deodorizing method, a lateral swirl flow of air laterally
swirling along the inner surface of a rim portion or the like of the toilet main body
is formed by discharging air into the toilet main body through the discharge port
and suctioning air in the toilet main body through the suction port. Accordingly,
it is possible to attract an odor in the toilet main body, to suction the odor through
the suction port, and to deodorize the odor suctioned through the suction port by
using the deodorizing device.
[0032] Moreover, according to the toilet deodorizing method, in addition to a lateral swirl
flow of air, a traversal flow of air traversing the inside of the toilet main body
is formed. Accordingly, it is possible to attract an odor staying in a middle portion
of the toilet main body, that is, on an inner side of the lateral swirl flow of air
along with the traversal flow, to suction the odor through the suction port, and to
deodorize the odor suctioned through the suction port by using the deodorizing device.
[0033] As a result, it is possible to capture an odor more efficiently and effectively and
to deodorize odors during defecation and after defecation. For example, it is possible
to prevent air in the middle portion of the toilet main body from being taken upward
when a user stands up from a toilet seat and to prevent an odor from being diffused.
[0034] According to a second aspect of the present invention, the toilet deodorizing method
according to the first aspect may further include forming at least a plurality of
the lateral swirl flows and a plurality of the traversal flows in the toilet main
body by discharging air into the toilet main body through the discharge port and by
suctioning air in the toilet main body through the suction port.
[0035] According to the toilet deodorizing method, a plurality of lateral swirl flows of
air and/or a plurality of traversal flows of air are formed in the toilet main body.
Accordingly, it is possible to more effectively capture an odor staying in the middle
portion of the toilet main body and all odors in the toilet main body and to deodorize
the odors.
[0036] According to a third aspect of the present invention, the toilet deodorizing method
according to the first or second aspect may further include forming a vertical swirl
flow of air vertically swirling along the inner surface of the toilet main body by
discharging air into the toilet main body through the discharge port and by suctioning
air in the toilet main body through the suction port.
[0037] According to the toilet deodorizing method, a vertical swirl flow of air vertically
swirling along the inner surface of the toilet main body is formed by discharging
air into the toilet main body through the discharge port and suctioning air in the
toilet main body through the suction port. Accordingly, it is possible to attract
an odor in the toilet main body, to suction the odor through the suction port, and
to deodorize the odor suctioned through the suction port by using the deodorizing
device.
[0038] Due to a vertical swirl (swirl having a swirl axis directed in a transverse direction)
of air, an odor rising upward from the toilet main body can be efficiently captured.
Accordingly, it is possible to capture an odor more efficiently and effectively and
to deodorize odors during defecation and after defecation. For example, it is possible
to prevent air in the middle portion of the toilet main body from being taken upward
when a user stands up from a toilet seat and to prevent an odor from being diffused.
[0039] According to a fourth aspect of the present invention, the toilet deodorizing method
according to any one of the first to third aspects may further include forming at
least the lateral swirl flow and the traversal flow of air by discharging air through
the discharge port such that at least a part of air becomes a vortex flow.
[0040] According to the toilet deodorizing method, at least a part of a lateral swirl flow
and/or a traversal flow of air formed in the toilet main body is a vortex flow. Accordingly,
while an ambient odor in a wide range is dragged in due to the vortex flow, it is
possible to send the odor to the suction port along flows of the lateral swirl flow
and/or the traversal flow of air and to suction the air.
[0041] Accordingly, it is possible to capture an odor in the toilet main body more efficiently
and effectively and to deodorize odors during defecation and after defecation. For
example, it is possible to more effectively prevent air in the middle portion of the
toilet main body from being taken upward when a user stands up from a toilet seat
and to more effectively prevent an odor from being diffused.
[0042] According to a fifth aspect of the present invention, the toilet deodorizing method
according to any one of the first to fourth aspects may further include discharging
air treated by the deodorizing device into the toilet main body through the discharge
port and causing the treated air to circulate.
[0043] According to the toilet deodorizing method, air treated by using the deodorizing
device is discharged into the toilet main body through the discharge port and is caused
to circulate. As a result, it is possible to cause air to circulate using a drive
device such as one air blower by discharging air into the toilet main body through
the discharge port and suctioning the air in the toilet main body through the suction
port. Accordingly, it is possible to efficiently perform deodorizing treatment.
[0044] According to a sixth aspect of the present invention, in the toilet deodorizing method
according to any one of the first to fifth aspects, the lateral swirl flow may be
caused to be an air flow stronger than the traversal flow.
[0045] According to the toilet deodorizing method, when a lateral swirl flow is caused to
be an air flow stronger than the traversal flow, it is possible to prevent a traversal
flow from flowing out of the toilet main body. As a result, it is possible to prevent
an odor from being diffused and to effectively perform deodorizing treatment.
[0046] According to a seventh aspect of the present invention, in the toilet deodorizing
method according to any one of the first to sixth aspects, the traversal flow may
be caused to join the lateral swirl flow and to be suctioned through the suction port.
[0047] According to the toilet deodorizing method, when a traversal flow is caused to join
a lateral swirl flow and to be suctioned through the suction port, even if a traversal
flow for capturing an odor in the middle portion of the toilet main body is formed
in addition to the lateral swirl flow, it is possible to send an odor dragged in by
the traversal flow to the suction port together with the lateral swirl flow and to
perform deodorizing treatment effectively and efficiently.
[0048] According to an eighth aspect of the present invention, there is provided a toilet
further includes a deodorizing device which deodorizes an air in a toilet main body.
The deodorizing device includes a discharge port that discharges air into the toilet
main body, a suction port that sucks air in the toilet main body, and a deodorizing
device that eliminates an odorous component of air suctioned through the suction port.
The deodorizing device is configured to form a lateral swirl flow of air laterally
swirling along an inner surface of the toilet main body and a traversal flow of air
traversing an inside of the toilet main body, by discharging air into the toilet main
body through the discharge port and by suctioning air in the toilet main body through
the suction port and to suction air, which flows due to the lateral swirl flow and
the traversal flow, through the suction port.
[0049] According to the toilet, a lateral swirl flow of air laterally swirling along the
inner surface of a rim portion or the like of the toilet main body is formed by discharging
air into the toilet main body through the discharge port and suctioning air in the
toilet main body through the suction port. Accordingly, it is possible to attract
an odor in the toilet main body, to suction the odor through the suction port, and
to deodorize the odor suctioned through the suction port by using the deodorizing
device.
[0050] Moreover, according to the toilet, in addition to a lateral swirl flow of air, a
traversal flow of air traversing the inside of the toilet main body is formed. Accordingly,
it is possible to attract an odor staying in a middle portion of the toilet main body,
that is, on an inner side of the lateral swirl flow of air along with the traversal
flow, to suction the odor through the suction port, and to deodorize the odor suctioned
through the suction port by using the deodorizing device.
[0051] As a result, it is possible to capture an odor more efficiently and effectively and
to deodorize odors during defecation and after defecation. For example, it is possible
to prevent air in the middle portion of the toilet main body from being taken upward
when a user stands up from a toilet seat and to prevent an odor from being diffused.
[0052] According to a ninth aspect of the present invention, in the toilet according to
the eighth aspect, an air direction adjusting member may be provided in the discharge
port. Air to be discharged through the discharge port flows through the air direction
adjusting member, the air direction adjusting member may include a lateral swirl flow
forming portion discharging air toward the inner surface of the toilet main body and
forming the lateral swirl flow of air laterally swirling along the inner surface of
the toilet main body, and a traversal flow forming portion discharging air toward
an inner side of the toilet main body and forming the traversal flow of air traversing
the inside of the toilet main body.
[0053] According to the toilet, when the air direction adjusting member including the lateral
swirl flow forming portion and the traversal flow forming portion is provided in the
discharge port, it is possible to discharge air through one discharge port and to
form a lateral swirl flow of air laterally swirling along the inner surface of the
toilet main body and a traversal flow of air traversing the inside of the toilet main
body at the same time.
[0054] In addition, when the sizes (area ratio or the like) of the lateral swirl flow forming
portion and the traversal flow forming portion are adjusted, it is possible to freely
and easily adjust the flow ratio of the lateral swirl flow and the traversal flow
of air such that an odor in the toilet main body can be preferably captured and deodorized.
[0055] According to a tenth aspect of the present invention, in the toilet according to
the eighth or ninth aspect, the deodorizing device may be configured to form a vertical
swirl flow of air vertically swirling along the inner surface of the toilet main body
by discharging air into the toilet main body through the discharge port and by suctioning
air in the toilet main body through the suction port.
[0056] According to the toilet, a vertical swirl flow of air vertically swirling along the
inner surface of the toilet main body is formed by discharging air into the toilet
main body through the discharge port and suctioning air in the toilet main body through
the suction port. Accordingly, it is possible to attract an odor in the toilet main
body, to suction the odor through the suction port, and to deodorize the odor suctioned
through the suction port by using the deodorizing device.
[0057] Due to a vertical swirl (swirl having a swirl axis directed in a transverse direction)
of air, an odor rising upward from the toilet main body can be efficiently captured.
Accordingly, it is possible to capture an odor more efficiently and effectively and
to deodorize odors during defecation and after defecation. For example, it is possible
to prevent air in the middle portion of the toilet main body from being taken upward
when a user stands up from a toilet seat and to prevent an odor from being diffused.
[0058] According to an eleventh aspect of the present invention, in the toilet according
to the eighth to ninth aspects, the deodorizing device may include a vortex flow generating
device at least the discharge port and the suction port. The deodorizing device may
be configured to form at least the lateral swirl flow and the traversal flow of air
such that at least a part of the air becomes a vortex flow by the vortex flow generating
device.
[0059] According to the toilet, at least a part of the lateral swirl flow and/or the traversal
flow of air formed in the toilet main body is a vortex flow. As a result, while an
ambient odor in a wide range is dragged in due to the vortex flow, it is possible
to send the odor to the suction port along flows of the lateral swirl flow and/or
the traversal flow of air and to suction the air.
[0060] Accordingly, it is possible to capture an odor in the toilet main body more efficiently
and effectively and to deodorize odors during defecation and after defecation. For
example, it is possible to more efficiently prevent air in the middle portion of the
toilet main body from being taken upward when a user stands up from a toilet seat
and to more efficiently prevent an odor from being diffused.
[0061] According to a twelfth aspect of the present invention, a toilet deodorizing device
includes a deodorizing flow channel through which a suction port and a discharge port
are connected to each other and through which air including an odor flows; a deodorizer
which includes a deodorizing portion that is provided in the deodorizing flow channel
and that deodorizes an odor from air flowing through; and a bypass passage which is
provided in the deodorizing flow channel and through which air not passing through
the deodorizing portion of the deodorizer passes.
[0062] According to the toilet deodorizing device, most of air to be flowing into the deodorizing
flow channel through the suction port is deodorized via the deodorizing portion of
the deodorizer, and the remaining part of the air passes through the bypass passage
away from the deodorizing portion, so that air resistance is reduced. Consequently,
the flow speed and the flow rate of air flowing in through the suction port and passing
through the deodorizing flow channel increase. Therefore, it is possible to improve
deodorizing efficiency.
[0063] According to a thirteenth aspect of the present invention, in the toilet deodorizing
device according to the twelfth aspect, the bypass passage may be formed on an outer
surface of the deodorizer or inside thereof.
[0064] According to the toilet deodorizing device, when the bypass passage is formed on
the outer surface of the deodorizer or inside thereof, a bypass passage can be easily
installed without widening the deodorizing flow channel. Therefore, it is possible
to increase the flow speed and the flow rate of air flowing in through the suction
port and to perform efficient deodorizing by using the deodorizer.
[0065] According to a fourteenth aspect of the present invention, in the toilet deodorizing
device according to the twelfth aspect, the bypass passage may be formed outside being
isolated from the deodorizer.
[0066] According to the toilet deodorizing device, when the bypass passage is installed
outside being isolated from the deodorizer, it is possible to increase the flow speed
and the flow rate of air flowing in through the suction port and to perform efficient
deodorizing by using the deodorizer, without deteriorating deodorizing efficiency
of the deodorizer used for deodorizing air.
[0067] According to a fifteenth aspect of the present invention, in the toilet deodorizing
device according to the twelfth or thirteenth aspect, the deodorizer may include the
deodorizing portion and a cover member covering the deodorizing portion. A part of
the cover member may be cut out such that the part serves as the bypass passage.
[0068] According to the toilet deodorizing device, the bypass passage is provided by cutting
out the cover member of the deodorizing portion adsorbing an odor included in air.
Therefore, it is possible to form the bypass passage by using a cutout portion without
damaging the deodorizing portion.
[0069] According to a sixteenth aspect of the present invention, in the toilet deodorizing
device according to the fifteenth aspect, the cover member may be an elastic member
with waterproof.
[0070] According to the toilet deodorizing device, due to the waterproof cover member covering
the deodorizing portion, it is possible to prevent moisture from infiltrating into
the deodorizing portion or the cover member. In addition, no water leak occurs between
a case such as a deodorizing duct protecting the deodorizer, and the cover member.
[0071] According to a seventeenth aspect of the present invention, in the toilet deodorizing
device according to any one of the twelfth to sixteenth aspects, the suction port
and the discharge port may be open in a toilet bowl.
[0072] According to the toilet deodorizing device, the suction port and the discharge port
of the deodorizing flow channel are open in the toilet bowl. Therefore, a stagnant
odor in the toilet bowl is caused to flow in at a high speed together with air through
the suction port and is adsorbed by the deodorizer, and the air is discharged into
the toilet bowl at a high speed, so that a swirl flow channel is formed in the toilet
bowl. As a result, a high-speed circulation flow channel is formed between the swirl
flow channel and the deodorizing flow channel in the deodorizing device, and it is
possible to efficiently collect an odor and to carry out ventilation.
[0073] According to an eighteenth aspect of the present invention, a toilet includes a deodorizing
device which deodorizes an odor in a toilet bowl having an opening of a toilet main
body. The deodorizing device includes a suction port, a discharge port, a deodorizing
flow channel through which air including an odor flows by suctioning through the suction
port, a deodorizer which is provided in the deodorizing flow channel and deodorizes
the odor from air flowing through, and an air blower which is provided in the deodorizing
flow channel. While having an upper surface of the toilet main body as a reference
plane, the suction port and the discharge port are open in the toilet bowl of the
toilet main body, and at least a part of the suction port and the discharge port are
installed on a side lower than the reference plane.
[0074] According to the toilet, while having the upper surface of the toilet bowl as the
reference plane, at least a part of the suction port and the discharge port is installed
on a side lower than the reference plane. Therefore, the suction port and the discharge
port are installed in the opening of the toilet bowl. As a result, it is possible
to cause an air flow to efficiently circulate between the deodorizing flow channel
of the deodorizing device and the inside of the opening of the toilet bowl via the
suction port and the discharge port, and it is possible to efficiently deodorize and
collect an odor included in an air flow by using the deodorizing device.
[0075] The discharge port may be the discharge port of the deodorizing flow channel and,
for example, may be a discharge port or the like of a different member such as a warm
air drying unit.
[0076] According to a nineteenth aspect of the present invention, in the toilet according
to the eighteenth aspect, the deodorizing device may be configured to discharge air
such that the air flows into the opening of the toilet main body through the discharge
port in a substantially horizontal manner.
[0077] According to the toilet, when at least a part of the suction port and the discharge
port of air in the deodorizing device is set to a level equal to or lower the reference
plane, it is possible to regulate discharging air discharged into the toilet bowl
through the discharge port such that the discharging air flows in the opening of the
toilet bowl in a substantially horizontal manner. Accordingly, an air flow flowing
in the toilet bowl is introduced while its vertical movement is suppressed when flowing
into the suction port.
[0078] According to a twentieth aspect of the present invention, in the toilet according
to the eighteenth or nineteenth aspect, a concave portion which is positioned in a
part facing the opening of the toilet main body on a side lower than the reference
plane may be formed in the toilet main body. The deodorizing flow channel of the deodorizing
device may be installed in the concave portion and may be positioned on a side lower
than the reference plane, and the discharge port may be installed on a side lower
than the reference plane.
[0079] According to the toilet, when the deodorizing flow channel is installed in the concave
portion of the toilet bowl, the deodorizing flow channel can be positioned on a side
lower than the reference plane. Therefore, since an air flow flowing in the deodorizing
flow channel on a side lower than the reference plane does not vertically move, it
is possible to reduce a pressure loss.
[0080] According to a twenty-first aspect of the present invention, in the toilet according
to the twentieth aspect, a nozzle unit that washes a private part may be installed
on an upper side of the deodorizing flow channel.
[0081] According to the toilet, when the deodorizing flow channel of the deodorizing device
is installed on a lower side and the nozzle unit is arranged above thereof, it is
possible to shorten the deodorizing flow channel and to reduce a pressure loss.
[0082] According to a twenty-second aspect of the present invention, in the toilet according
to any one of the eighteenth to twenty-first aspects, the suction port may be installed
on a side lower than the reference plane.
[0083] According to the toilet, when the suction port is installed on a side lower than
the reference plane, an air flow which is discharged through the discharge port and
swirls in the toilet bowl can entangle a stagnant odor in the toilet bowl and can
be guided to the suction port. As a result, it is possible to improve circulation
efficiency of an air flow and deodorizing efficiency of an odor.
[0084] According to a twenty-third aspect of the present invention, the toilet according
to the twentieth aspect may further include a base in which a convex portion protruding
downward is formed and a concave recess portion is formed on an upper surface of the
convex portion. The deodorizing device may be installed in the concave recess portion.
The convex portion may be fitted in the concave portion formed in the toilet bowl.
[0085] According to the toilet, when the deodorizing device is installed in the concave

other end on the downstream side is connected to the downstream side of the heater
112c of the warm air duct 112b. That is, in the present embodiment A1, the downstream
side of the warm air duct 112b and the downstream side of the deodorizing duct 113a
serve as a common passage, and the warm air duct 112b and the deodorizing duct 113a
are configured to share the discharge port 117.
[0151] In addition, a damper 119 for switching passages and regulating air volume is provided
in a connection portion between the deodorizing duct 113a and the warm air duct 112b.
The opening ratios of the warm air duct 112b and the deodorizing duct 113a are configured
to be capable of being regulated in accordance with a control angle of the damper
119.
[0152] For example, the deodorizing cartridge 113c includes an adsorption-type deodorant
such as activated carbon and eliminates an odor included in air passing through by
means of the deodorant. There is no need to particularly limit the deodorant as long
as the deodorant is capable of deodorization. For example, the deodorant may be a
catalyst or a decomposition-type deodorant such as a photocatalyst which decomposes
a substance by emitting a ray of light such as an ultraviolet ray.
[0153] For example, it is preferable that the sterilizing unit generates sterilizing ions,
suppresses propagation of floating fungi, performs sterilization, generates positive
ions and negative ions by ionizing air, and inactivating floating fungi by surrounding
the floating fungi due to the positive ions and the negative ions.
[0154] In addition, in the present embodiment A1, as shown in FIG. 4, an air direction adjusting
member 120 is attached to the discharge port 117 for discharging air which has passed
through the deodorizing duct 113a. The air direction adjusting member 120 divides
the discharge port 117 into an upper portion and a lower portion having a border in
a substantial middle in the upward/downward direction. Furthermore, the air direction
adjusting member 120 is formed to include air direction plates in the upper portion
and the lower portion having directions different from each other such that air passing
through the upper portion and the lower portion blows in directions different from
each other.
[0155] In the air direction adjusting member 120 of the present embodiment A1, a lateral
swirl flow forming portion 121 is provided in the upper portion and a traversal flow
forming portion 122 is provided in the lower portion.
[0156] The lateral swirl flow forming portion 121 is provided to cause air discharged through
the discharge port 117 to flow through, to discharge air toward the inner surface
of the toilet main body 11, and to form a lateral swirl flow R1 of air laterally swirling
along an inner surface of the toilet main body 11. The traversal flow forming portion
122 is provided to discharge air toward the inner side of the toilet main body 11
and to form a traversal flow R2 of air traversing the inside of the toilet main body
11.
[0157] Next, description will be given regarding a deodorizing method during defecation
and after defecation, in the flush toilet 1A of the present embodiment A1 having the
configuration described above. Operational effects of the deodorizing method of the
flush toilet 1A, and the flush toilet 1A of the present embodiment A1 will be described.
[0158] First, when a user sits on a toilet seat, it is detected by a sensor (detecting device),
and a detection signal is sent to a control device (control means). The control device
controls driving of the fan 113b of the deodorizing unit 113 and controls such that
air in the toilet main body 11 is suctioned through the suction port 118, odorous
components are eliminated and decomposed by the deodorizing cartridge 113c while the
air suctioned through the suction port 118 flows through the deodorizing duct 113a,
and the treated air is discharged through the discharge port 117.
[0159] As shown in FIG. 2, in the flush toilet 1A of the present embodiment A1, the air
direction adjusting member 120 is provided in the discharge port 117. In the deodorizing
method of the flush toilet 1A, and the flush toilet 1A of the present embodiment A1,
the air direction adjusting member 120 is configured to discharge air passing through
the lateral swirl flow forming portion 121 on the upper portion side, toward the rim
portion 11b of the toilet main body 11 and to discharge air passing through the traversal
flow forming portion 122 on the lower portion side, toward a substantial center of
the toilet main body on the inner side above the water sealing portion 11d of the
toilet main body 11.
[0160] The rim portion 11b includes an overhanging portion which is formed on the upper
portion thereof, protrudes to the inner side of the toilet main body 11, and continuously
leads from the rear portion side of the toilet main body 11 to a front portion side
in an annular state. Therefore, air discharged toward the rim portion 11b of the toilet
main body 11 first flows through from the rear portion side to the front portion side
of the toilet main body 11 along one of the right and left sides of the rim portion
11b. The air flows through from the front portion side to the rear portion side along
the other of the right and left sides and is suctioned through the suction port 118.
Then, the air is treated by the deodorizing cartridge 113c in the deodorizing duct
113a and is discharged again through the discharge port 117.
[0161] In this manner, when the lateral swirl flow R1 of a lateral swirl flowing along the
rim portion 11b in an annular state is formed, an odor generated in the toilet main
body 11 is dragged into the lateral swirl flow R1 and is sequentially subjected to
deodorizing treatment by the deodorizing cartridge 113c. In addition, since the lateral
swirl flow R1 is formed, an odor can be inhibited from flowing out of the toilet main
body 11.
[0162] In addition, in the present embodiment A1, air passing through the traversal flow
forming portion 122 on the upper portion side of the air direction adjusting member
120 is discharged toward the inner side of the toilet main body 11. This air flows
so as to traverse the inside surrounded by the lateral swirl flow R1, that is, the
inside of the toilet main body 11 in a substantially linear manner. Accordingly, the
traversal flow R2 joins the lateral swirl flow R1 while attracting an odor of the
inside surrounded by the lateral swirl flow R1, that is, in a middle part of the toilet
main body 11.
[0163] The lateral swirl flow R1 is formed by air discharged through the discharge port
117. Accordingly, an odor generated in the toilet main body 11 is dragged in the lateral
swirl flow R1 and is sequentially subjected to deodorizing treatment. Moreover, an
odor staying in the middle part of the toilet main body 11, in which dragging force
of the lateral swirl flow R1 is weakened, is dragged into the traversal flow R2, is
transferred, is caused to join and ride on the lateral swirl flow R1, and is able
to be sequentially subjected to deodorizing treatment.
[0164] Thus, in the deodorizing method of the flush toilet 1A, and the flush toilet 1A of
the present embodiment A1, the lateral swirl flow R1 and the traversal flow R2 can
be formed due to air discharged through the discharge port 117, and an odor in a center
part of the lateral swirl flow R1 of air, that is, in a middle part of the toilet
main body 11 can be transferred by the traversal flow R2 and can ride on the lateral
swirl flow R1. As a result, in the deodorizing method of the flush toilet 1A, and
the flush toilet 1A of the present embodiment A1, it is possible to restrain an odor
from staying and stagnating in a middle part of the toilet main body 11 and to efficiently
perform deodorization.
[0165] In this manner, since deodorization is performed using both the lateral swirl flow
R1 and the traversal flow R2 and an odor can be restrained from staying and stagnating
in a middle part of the toilet main body 11, it is possible to prevent an odor in
the toilet main body 11 from rising upward from the toilet main body 11 and being
diffused not only during defecation but also when a user stands up after defecation.
[0166] In addition, since the traversal flow R2 is formed on the inner side of the lateral
swirl flow R1, the traversal flow R2 acts as a lid, so that an odor in a middle part
of the toilet main body 11 can be restrained from rising upward.
[0167] Consequently, according to the deodorizing method of the flush toilet 1A, and the
flush toilet 1A of the present embodiment A1, it is possible to efficiently and effectively
capture an odor and to effectively deodorize an air during defecation and after defecation
compared to those in the related art.
[0168] In addition, air discharged through the discharge port 117 is suctioned through the
suction port 118, is subjected to deodorizing treatment by the deodorizing cartridge
113c, and is discharged through the discharge port 117 again, thereby circulating.
Therefore, when treatment is performed using the deodorizing cartridge 113c, circulating
air can be subjected to deodorizing treatment multiple times. Therefore, odorous components
are not necessarily subjected to deodorizing treatment by using a high-performance
deodorant with high efficiency close to 100%. The odorous components can be suitably
treated through multiple times of circulation using a low-performance deodorant. Accordingly,
it is possible to achieve cost reduction in the deodorizing unit 113.
[0169] In addition, the air direction adjusting member 120, in which air passing through
the lower portion side is discharged toward the rim portion 11b of the toilet main
body 11 and air passing through the upper portion side is discharged toward the inner
side of the toilet main body 11 such that the air traverses the inner side thereof,
is provided in one discharge port 117. As a result, the lateral swirl flow R1 and
the traversal flow R2 of air can be formed.
[0170] That is, since air is discharged through one discharge port 117, the lateral swirl
flow R1 and the traversal flow R2 of air can be formed at the same time.
[0171] Furthermore, for example, it is possible to easily adjust the flow rate of air discharged
through each of the parts in the upper portion and the lower portion of the air direction
adjusting member 120 by replacing the air direction adjusting member 120 with an air
direction adjusting member 120 in which the sizes (area ratio or the like) of the
lateral swirl flow forming portion 121 in the upper portion and the traversal flow
forming portion 122 in the lower portion are different from each other. Accordingly,
the flow rates of the lateral swirl flow R1 and the traversal flow R2 can be easily
adjusted. Due to this adjustment, deodorization can be performed by efficiently forming
the lateral swirl flow R1 and causing the traversal flow R2 to attract an odor in
the toilet main body 11 and to join the lateral swirl flow R1.
[0172] In addition, the air direction adjusting member 120 may be a variable-type member
in which the direction of an adjustment portion (vane portion) can be changed. In
this case, the direction of discharging air can be suitably changed, so that the lateral
swirl flow R1 and the traversal flow R2 can be formed such that deodorizing treatment
can be effectively performed.
[0173] In addition, in a case of a configuration in which a motion of a user standing up
from the toilet seat is detected, driving of the fan 113b of the deodorizing unit
113 is controlled by the control device which has received the detection result, and
the output of the fan 113b is raised as soon as the motion of the user standing up
from the toilet seat is detected, so that stronger discharging and suctioning of air
are performed, it is possible to more effectively prevent an odor from rising upward
from the inside of the toilet main body 11 and being diffused following the standing-up
motion of a user.
[0174] Furthermore, when an air flow of the lateral swirl flow R1 is caused to be stronger
than an air flow of the traversal flow R2, it is possible to prevent the traversal
flow R2 from flowing out of the toilet main body 11. As a result, it is possible to
prevent an odor from being diffused and to effectively perform deodorizing treatment.
[0175] In addition, when the traversal flow R2 is caused to join the lateral swirl flow
R1 and to be suctioned through the suction port 118, even if the traversal flow R2
for capturing an odor in the middle portion of the toilet main body 11 is formed in
addition to the lateral swirl flow R1, it is possible to send an odor dragged in by
the traversal flow R2 to the suction port 118 together with the lateral swirl flow
R1 and to perform deodorizing treatment effectively and efficiently.
[0176] Hereinabove, the embodiment A1 for the toilet deodorizing method and the toilet according
to the present invention has been described. However, the present invention is not
limited to the embodiment A1 and can be suitably changed within a range not departing
from the gist thereof.
[0177] For example, in the present embodiment A1, the lateral swirl flow R1 and the traversal
flow R2 can be formed through one discharge port 117 at the same time. However, as
shown in FIG. 5, another discharge port 117 for discharging air and forming the traversal
flow R2 may be separately provided from the discharge port 117 forming the lateral
swirl flow R1.
[0178] In addition, as shown in FIG. 6, the suction port 118 suctioning the traversal flow
R2 may be provided separately from the suction port 118 for the lateral swirl flow
R1.
[0179] Furthermore, as shown in FIGS. 7 and 8, a plurality of discharge ports 117 and/or
a plurality of suction ports 118 may be provided. In addition, a plurality of lateral
swirl flows R1 of air may be formed on the inner side of the toilet main body 11 by
discharging and suctioning air through the plurality of discharge ports 117 and/or
the plurality of suction ports 118.
[0180] In addition, as shown in FIGS. 7 and 8, due to one air flow (continuous dotted line
in the drawing, an air flow indicated with arrows) formed by discharging and suctioning
air through the plurality of discharge ports 117 and/or the plurality of suction ports
118, the lateral swirl flow R1 flowing along the inner surface of the toilet main
body 11 and the traversal flow R2 traversing the inner side of the toilet main body
11 may be sequentially formed. In other words, the present embodiment A1 may employ
a configuration in which one air flow formed by discharging and suctioning air through
the plurality of discharge ports 117 and/or the plurality of suction ports 118 changes
from the lateral swirl flow R1 to the traversal flow R2 and from the traversal flow
R2 to the lateral swirl flow R1.
[0181] Furthermore, positions for providing the discharge port 117 and the suction port
118 are not particularly limited as long as air in the toilet main body 11 can be
suctioned and deodorizing treatment can be performed. For example, the discharge port
17 and the suction port 18 may be formed in the toilet main body 11, may be formed
on the front portion side of the toilet main body 11, or may be formed in the toilet
seat 13a or the toilet lid 13b.
[0182] In addition, the inside of the hollow toilet main body 11, or the inner side of the
toilet seat 13a or the toilet lid 13b may serve as a flow channel for air, and the
deodorizing cartridge (deodorizing device) 113c may be provided inside the hollow
toilet main body 11 or on the inner side of the toilet seat 13a or the toilet lid
13b.
[0183] In addition, the present embodiment A1 may employ a configuration in which the plurality
of discharge ports 117 or the plurality of suction ports 118 are provided at predetermined
intervals in a circumferential direction of the hollow toilet main body 11, the toilet
seat 13a, or the toilet lid 13b, such that deodorization is performed by discharging
air to the inner side of the toilet main body 11 in multiple directions (radial directions
or the like) and suctioning air in multiple directions.
[0184] Furthermore, he present embodiment A1 may employ a configuration in which an air
flow of the lateral swirl flow R1 or the traversal flow R2 is formed due to suctioning
force of suctioning air through the suction port 118, instead of forming an air flow
of the lateral swirl flow R1 or the traversal flow R2 due to discharging force of
discharging air through the discharge port 117. In addition, as a matter of course,
an air flow may be formed by using both discharging force and suctioning force.
[0185] Even in a case of such a configuration, an odor in the middle portion of the toilet
main body 11 can be efficiently deodorized, so that it is possible to achieve operational
effects similar to those of the present embodiment A1.
[0186] In addition, a plurality of lateral swirl flows R1 or a plurality of traversal flows
R2 may be formed in an upward/downward direction T3.
[0187] For example, when a plurality of traversal flows R2 are formed vertically, an upper
traversal flow R2 can capture an odor which rising upward without being captured by
the traversal flow R2. Accordingly, it is possible to more efficiently prevent an
odor from being diffused. In addition, due to an upper traversal flow R2 acting as
a lid, an odor can be efficiently captured by a lower traversal flow R2 and can be
deodorized.
[0188] In addition, the present embodiment A1 has presented an example in which air circulates
such that air discharged through the discharge port 117 of the deodorizing unit 113
is caused to swirl, is suctioned through the suction port 118, is subjected to deodorizing
treatment by the deodorizing cartridge 113c, and is then discharged through the discharge
port 117 again. Moreover, the present embodiment A1 may employ a configuration in
which air discharged through the discharge port 117 of the deodorizing unit 113 is
caused to swirl, the lateral swirl flow R1 which has captured an odor is suctioned
through the suction port 118, the air is subjected to deodorizing treatment by the
deodorizing cartridge 113c, and the air is then discharged to the outside. That is,
air does not necessarily have to circulate.
[0189] Next, with reference to FIG. 9, a toilet deodorizing method and a toilet according
to an embodiment A2 of the present invention will be described. Similar to the embodiment
A1, the present embodiment A2 relates to means and a method in which deodorization
is performed by discharging air into a toilet main body through a discharge port and
suctioning air in the toilet main body through a suction port. Thus, in the present
embodiment A2, the same reference signs are applied to configurations similar to those
of the embodiment A1, and descriptions thereof are omitted.
[0190] In the embodiment A1, air is discharged through the discharge port 117 of the deodorizing
unit 113, the air is caused to laterally swirl along the rim portion 11b of the toilet
main body 11, and the air is suctioned through the suction port 118, thereby circulating.
On the other hand, in the flush toilet 1A of the present embodiment A2, as shown in
FIG. 9, air circulates due to a vertical swirl from the rim portion 11b side to the
water sealing portion 11d side and from the water sealing portion 11d side to the
rim portion 11b side.
[0191] Specifically, in the present embodiment A2, the discharge port 117 and the suction
port 118 are arranged on the rear portion side of the toilet main body 11. In the
present embodiment A2, air is discharged toward the inner surface of the toilet main
body 11 on the front portion side through the discharge port 117, and a traversal
flow of air headed for the front portion side from the rear portion side is formed
on the upper portion side in the toilet main body 11.
[0192] In addition, for example, an air inducing surface 11c, which is gradually inclined
to the front side toward the lower side from above and is inclined to the rear side
toward the further lower side in a smoothly connected manner, is formed in an upper
portion on the inner surface of the toilet main body 11 on the front portion side.
[0193] Accordingly, in the present embodiment A2, a linear flow of air discharged through
the discharge port 117 comes into contact with the upper portion side of the air inducing
surface 11c and flows downward along the air inducing surface 11c, and air flows on
the lower side in the toilet main body 11 from the front portion side toward the rear
portion side. As soon as the air arrives at the rear portion side of the toilet main
body 11, the air rises upward and is suctioned through the suction port 118.
[0194] Thus, in the deodorizing method of the flush toilet 1A, and the flush toilet 1A of
the present embodiment A2, a vertical swirl flow R3 can be formed by discharging air
to the inner side of the toilet main body 11 through the discharge port 117 and suctioning
air in the toilet main body 11 through the suction port 118. It is possible to deodorize
an odor in the toilet main body 11 by forming the vertical swirl flow R3 of air in
this manner. Therefore, in the deodorizing method of the flush toilet 1A, and the
flush toilet 1A of the present embodiment A2, it is possible to achieve operational
effects similar to those of the deodorizing method of the flush toilet 1A, and the
flush toilet 1A of the embodiment A1.
[0195] In addition, in the present embodiment A2, the vertical swirl flow R3 of air is formed
and a linear flow of air is formed in an upper side of the toilet main body 11. Accordingly,
a linear flow of the air acts as a lid, so that it is possible to prevent an odor
from rising upward and being diffused from the inside of the toilet main body 11.
In addition, since an odor rising upward from the inside of the toilet main body 11
can be effectively captured by a linear flow of air, it is possible to effectively
and efficiently perform deodorization.
[0196] Hereinabove, the embodiment A2 for the toilet deodorizing method and the toilet according
to the present invention has been described. However, the present invention is not
limited to the embodiment A2 and can be suitably changed within a range not departing
from the gist thereof.
[0197] The vertical swirl flow R3 of the present embodiment A2 may be formed in combination
with the configuration disclosed in the embodiment A1, or by suitably and selectively
applying the configuration of the embodiment A1 and the configuration of a modification
example.
[0198] For example, the number of vertical swirl flows R3, the air flow direction of the
vertical swirl flow R3, the forming position of the vertical swirl flow R3, and the
like are not necessarily have to be limited to those of the present embodiment A2.
[0199] Next, with reference to FIGS. 10 and 11, a toilet deodorizing method and a toilet
according to an embodiment A3 of the present invention will be described.
[0200] Similar to the embodiments A1 and A2, the present embodiment A3 relates to means
and a method in which deodorization is performed by discharging air into a toilet
main body through a discharge port and suctioning air in the toilet main body through
a suction port. Thus, in the present embodiment A3, the same reference signs are applied
to configurations similar to those of the embodiments A1 and A2, and descriptions
thereof are omitted.
[0201] In the present embodiment A3, disposition and the like of the discharge port 117
for discharging air and the suction port 118 for suctioning air in the deodorizing
unit 113 are similar to those of the configuration of the embodiment A1, the configuration
of the embodiment A2, and the configurations of modification examples thereof. In
the present embodiment A3, the lateral swirl flow R1, the traversal flow R2, and a
plurality of lateral swirl flows R1 and traversal flows R2 of the embodiment A1, and
the vertical swirl flow R3 of the embodiment A2 are formed by discharging air through
the discharge port 117 and suctioning air into the suction port 118.
[0202] Meanwhile, in the present embodiment A3, as shown in FIGS. 10 and 11, when the lateral
swirl flow R1, the traversal flow R2, the vertical swirl flow R3, and the like are
formed, at least a part there of includes a vortex flow R4.
[0203] For example, vortex flow generating means such as a tube including a spiral passage
on an inner side is provided in the discharge port 117 and/or the suction port 118
of the deodorizing unit 113. That is, when air passes through the vortex flow generating
means, swirling force acts on the air. A lateral vortex flow R4 having a vortex axis
directed in the flow direction (transverse direction) is formed on the front side
in the air flow direction (discharging direction) through the discharge port 117 and/or
is formed on the rear side in the air flow direction (suctioning direction) through
the suction port 118.
[0204] Accordingly, while the lateral vortex flow R4 having the vortex axis directed in
the transverse direction is formed in the toilet main body 11, air flows as the lateral
swirl flow R1, the traversal flow R2, or the vertical swirl flow R3 of the embodiment
A1 or the embodiment A2. Since the lateral vortex flow R4 is formed in at least a
part of the lateral swirl flow R1, the traversal flow R2, or the vertical swirl flow
R3, an odor in the toilet main body 11 is efficiently is dragged into the lateral
vortex flow R4, as well as the lateral swirl flow R1, the traversal flow R2, and the
vertical swirl flow R3. Accordingly, an odor in the toilet main body 11 is suctioned
through the suction port 118 and is sequentially subjected to deodorizing treatment.
[0205] Thus, in this case, since an air flow including the lateral vortex flow R4 flows
in the toilet main body 11, many ambient odors are dragged therein compared to a linear
flow, and an odor in the toilet main body 11 can be efficiently captured. Then, the
air flow is suctioned through the suction port 118 and is treated by the deodorizing
cartridge 113c. Therefore, it is possible to perform efficient deodorization.
[0206] In addition, for example, an obstacle (vortex flow generating device) such as a columnar
rod is installed in the discharge port 117 while its axial direction is directed in
the upward/downward direction or the transverse direction (horizontal direction).
When air to be discharged through the discharge port 117 is brought into contact with
the obstacle and is discharged into the toilet main body 11, a Karman vortex (vortex
flow R4) is formed on the downstream side of the obstacle in the air flow direction.
If an obstacle such as a cylindrical rod is formed in the discharge port while its
axial direction is directed in the upward/downward direction, a Karman vortex of which
the vortex axis is directed in the upward/downward direction is formed. If an obstacle
such as a cylindrical rod is formed in the discharge port while its axial direction
is directed in the transverse direction (horizontal direction), a Karman vortex of
which the vortex axis is directed in the transverse direction is formed.
[0207] Since an air flow including such a vortex flow R4 (Karman vortex) flows in the toilet
main body 11, many ambient odors are dragged therein compared to a linear flow, and
an odor in the toilet main body 11 is efficiently captured. Accordingly, the air flow
is suctioned through the suction port 118 and is treated by the deodorizing cartridge
113c. Therefore, it is possible to perform efficient deodorization.
[0208] Hereinabove, the embodiment A3 for the toilet deodorizing method and the toilet according
to the present invention has been described. However, the present invention is not
limited to the embodiment A3 and can be suitably changed within a range not departing
from the gist thereof.
[0209] The vortex flow R4 of the present embodiment A3 may be formed in combination with
the configurations disclosed in the embodiments A1 and A2, or by suitably and selectively
applying the configurations of the embodiments A1 and A2 and the configuration of
the modification example.
[0210] In addition, the present embodiment may employ a configuration in which an odor is
captured by forming the vortex flow R4 in a part on a side of the discharge port 117
or the suction port 118.
[0211] Next, a toilet deodorizing device according to an embodiment B1 of the present invention
will be described based on the accompanying drawings.
[0212] FIGS. 11 to 18 illustrate a deodorizing unit (deodorizing device) 213 of a toilet
21 according to the embodiment B1 of the present invention.
[0213] FIGS. 11 and 12 illustrate the flushing-type toilet 21 including a private part washing
device 23 of the embodiment B1. The toilet 21 includes the private part washing device
23 in the rear portion on the upper surface of a toilet main body 22. The private
part washing device 23 is included in a case 25 housing various functional components
for private part washing, warm air drying, and deodorizing. A toilet seat 27 and a
toilet lid 28 installed on the toilet main body 22 are attached to a cover 26 provided
in the case 25 so as to be capable of being individually opened and closed.
[0214] In FIG. 12, the toilet main body 22 has a toilet bowl 210 receiving filth, and a
drain pipe portion (not shown). The drain pipe portion extends downward from a bottom
portion of the toilet bowl 210. A rim water passage 225, a drop flow channel, and
the like are formed in an upper inner wall in the toilet bowl 210. The rim water passage
225 is formed in order to generate a swirl flow of washing water. The drop flow channel
is formed in order to form a flow for dropping a swirl flow toward the drain pipe
portion.
[0215] The private part washing device 23 is installed on a base 211 arranged at the rear
portion on an upper surface 210b forming an opening 210a of the toilet bowl 210. The
private part washing device 23 includes a nozzle unit 212, the deodorizing unit 213,
a warm air drying unit 214, and the like. The nozzle unit 212 includes a private part
washing nozzle (described below). The deodorizing unit 213 is provided in order to
deodorize an odor generated in the toilet bowl 210. The warm air drying unit 214 is
provided in order to dry a private part after washing with warm air. Furthermore,
the private part washing device 23 includes a warm water supply unit 215, a control
unit, a power supply board, and the like. The warm water supply unit 215 is provided
in order to supply warm water to the nozzle unit 212. The control unit is provided
in order to control driving of each of the units.
[0216] In the private part washing device 23 shown in FIGS. 12 and 13, the nozzle unit 212
is installed in the middle of the base 211 on a tip end side facing the opening 210a
of the toilet bowl 210. In the nozzle unit 212, as a pair of private part washing
nozzles, a first washing nozzle 216 and a second washing nozzle 217 are arranged in
parallel and are installed obliquely downward. The first washing nozzle 216 is a nozzle
for anus washing. The second washing nozzle 217 is a washing nozzle for bidet. Each
of the first and second washing nozzles 216 and 217 has a discharging hole for discharging
washing water, in the tip end portion positioned below.
[0217] The first and second washing nozzles 216 and 217 are interlinked with the warm water
supply unit 215 installed in the base 211, via piping. The warm water supply unit
215 selectively supplies warm water, which has been adjusted to a set temperature,
to the first and second washing nozzles 216 and 217 upon a command of the control
unit (not shown).
[0218] In addition, as shown in FIGS. 13, 15A, 15B, and 15C, a wide-width portion 221 extending
downward and having a wide width is provided in the middle of the base 211 on the
front surface facing the opening 210a of the toilet bowl 210. A pair of opening portions
218 is provided in the middle of the wide-width portion 221. The first and second
washing nozzles 216 and 217 can respectively protrude forward through the opening
portions 218 of the wide-width portion 221. A suction port 219 for sucking air including
an odor and a discharge port 220 for discharging deodorized air are formed on both
sides of the opening portions 218 in the wide-width portion 221.
[0219] In addition, a shutter 222 that operates an opening-closing operation over the pair
of opening portions 218, and the suction port 219 and the discharge port 220 on the
right and left sides of the pair of opening portions 218 is provided on the front
surface side of the wide-width portion 221. The shutter 222 exhibits a substantially
rectangular plate shape. The shutter 222 is held such that its rear surface is pulled
to the wide-width portion 221 side by a spring housed in a tube portion (not shown).
The shutter 222 is configured to be pivotable upward and downward by the first washing
nozzle 216 and the second washing nozzle 217.
[0220] That is, in a case where the first washing nozzle 216 protrudes downward, one projection
portion (not shown) formed on the rear surface of the shutter 222 is pushed and the
inner surface of the shutter 222 pivots upward, so that the shutter 222 is in an upwardly
open state. In a case where the second washing nozzle 217 protrudes downward, the
other projection portion (not shown) formed on the rear surface of the shutter 222
is pushed and the inner surface of the shutter 222 pivots downward, so that the shutter
222 is in a downwardly open state.
[0221] At the time of washing by the first washing nozzle 216, the second washing nozzle
217 protrudes downward and the shutter 222 is in a downwardly open state. Then, in
a state where the first washing nozzle 216 has moved forward beyond the shutter 222,
washing is performed by the first washing nozzle 216. In addition, in a case where
washing is performed by the second washing nozzle 217, the second washing nozzle 217
protrudes downward and the shutter 222 is in a downwardly open state. Furthermore,
in a state where the second washing nozzle 217 has moved forward beyond the shutter
222, washing is performed.
[0222] In addition, the base 211 for mounting the private part washing device 23 has a substantially
flat plate shape. However, a convex portion 223 which has a convex curve shape forming
a convexity downward throughout a part from the wide-width portion 221 to the tip
end side of the base 211 is formed in the middle of its tip end side.
[0223] Meanwhile, in the toilet main body 22 shown in FIG. 14, the upper surface 210b of
the toilet bowl 210 has a flat surface shape. On the upper surface 210b of the toilet
bowl 210, an edge part of a mount portion 210c for mounting the base 211 facing the
opening 210a forms a concave portion 224 which is recessed downward by a predetermined
range. When the base 211 is installed on the mount portion 210c of the toilet bowl
210, the convex portion 223 including the wide-width portion 221 of the base 211 sits
on and is fitted in the concave portion 224.
[0224] In FIGS. 15A to 15C, the mount portion 210c of the toilet main body 22 is included
in the upper surface 210b and forms the same plane. This plane is indicated as a reference
plane L called "ceramic zero surface". In the wide-width portion 221 of the base 211,
the pair of opening portions 218 through which the first and second washing nozzles
216 and 217 penetrate and move forward and rearward, and the suction port 219 and
the discharge port 220 on both sides thereof are positioned on a side lower than the
reference plane L in their entirety or a part of height portions.
[0225] In addition, in the opening 210a of the toilet bowl 210, the rim water passage 225
is formed along a lower circumferential surface of the circumferential edge portion
of the upper surface 210b. The rim water passage 225 is a grooved rim-shaped passage
formed to circle around along an inner side surface of the toilet bowl 210. The rim
water passage 225 generates a swirl flow of washing water for washing the toilet bowl
210.
[0226] In FIGS. 15B and 15C, for example, in the discharge port 220, openings are formed
vertically in two rows (or may be formed in the right/left direction) as an upper
discharge port 220a and a lower discharge port 220b. Ribs 230 are formed in each of
the upper discharge port 220a and the lower discharge port 220b, having directions
different from each other.
[0227] Air discharged through the upper discharge port 220a forms a swirl flow as a rim-shaped
passage along the inner side surface in the opening 210a of the toilet bowl 210. Air
discharged through the lower discharge port 220b is discharged in a direction obliquely
intersecting the inside of the opening 210a of the toilet bowl 210, thereby forming
a traversal flow. Air discharged through the lower discharge port 220b joins a swirl
flow from the upper discharge port 220a on the inner side surface of the toilet bowl
210 facing the discharge port 220. Air directions of a swirl flow and a traversal
flow can be regulated by using the ribs 230 installed in the upper discharge port
220a and the lower discharge port 220b. Therefore, the directions of the upper discharge
port 220a and the lower discharge port 220b may be reversely set.
[0228] As shown in FIG. 13, on the convex portion 223 in the middle of the base 211 on the
tip end side, the deodorizing unit 213 is installed on a side lower than the nozzle
unit 212. As shown in FIG. 16, the deodorizing unit 213 includes a deodorizing duct
226, a fan 227, a deodorizing cartridge 228, and a sterilizing unit 229.
[0229] The suction port 219 and the discharge port 220 formed in the wide-width portion
221 are interlinked with each other through the deodorizing duct 226. For example,
the deodorizing duct 226 is formed to be a deodorizing duct 226 having a substantially
U-shape or a substantially laid U-shape. The fan 227 is provided in the middle of
the deodorizing duct 226 as an air blower. The deodorizing cartridge 228 is installed
on the upstream side of the fan 227. The sterilizing unit 229 is installed on the
downstream side of the fan 227.
[0230] The deodorizing duct 226 is a passage of an air flow configuring a deodorizing flow
channel. The suction port 219 provided at an upstream end of the deodorizing duct
226 faces the opening 210a of the toilet bowl 210 and suctions air including an odor.
[0231] In FIG. 16, as a deodorizer, for example, the deodorizing cartridge 228 is installed
in the middle part of a flow channel of the deodorizing duct 226 of the deodorizing
unit 213. The deodorizing cartridge 228 is internally equipped with a deodorizing
catalyst and includes a deodorizing portion 231 which eliminates an odor included
in passing air. In the present embodiment B1, as shown in FIG. 17, the deodorizing
cartridge 228 includes the deodorizing portion 231 and a cover member 232.
[0232] The deodorizing portion 231 is configured by an adsorption-type deodorant having
activated carbon or the like as a catalyst. The cover member 232 covers an outer circumferential
surface of the deodorizing portion 231 and is formed to be a thin layer configured
by an elastic member, for example, a sponge having waterproof property and elastic
property.
[0233] A suitable shape can be employed for the deodorizing portion 231. For example, the
deodorizing portion 231 has a pentagonal prism shape formed by obliquely cutting off
one corner portion of a quadrangular prism shape and internally houses a deodorant
such as activated carbon. Otherwise, the deodorizing portion 231 may employ a decomposition-type
deodorant as a deodorant of a different type such as a photocatalyst having a function
of decomposing a substance by emitting an ultraviolet ray. The deodorizing portion
231 has the outer circumferential surface or the inner surface formed in a meshed
state in order to ensure ventilation. For example, the sponge of the cover member
232 is a closed-cell-type belt-like member having high waterproof property. The sponge
of the cover member 232 is wound around the side surface of the deodorizing portion
231.
[0234] Moreover, the deodorizing cartridge 228 has a cutout portion 233 formed by cutting
off a part of the cover member 232, for example, a part of the deodorizing portion
231 on the upper surface side. Otherwise, the cutout portion 233 may be formed on
the side surface or the bottom surface of the cover member 232. The cutout portion
233 configures a bypass passage in which inflow air bypasses the deodorizing portion
231 and flows to the downstream side. In the present embodiment B1, the cutout portion
233 is formed by cutting off the cover member 232 such as a sponge along the air flow
direction as much as a predetermined range of the thickness.
[0235] Therefore, most of air flowing in the deodorizing duct 226 passes through the deodorizing
portion 231 and is deodorized by the deodorizing cartridge 28. Then, a part thereof
passes the cover member 232, and another part thereof passes through the bypass passage
of the cutout portion 233 and flows to the downstream side. Since a part of air flowing
in the deodorizing duct 226 passes through the bypass passage of the cutout portion
233, ventilation property of the deodorizing cartridge 228 is improved. As a result,
it is possible to increase the air speed and the air volume of air flowing in through
the suction port 219 and flowing in the deodorizing duct 226.
[0236] In addition, the sterilizing unit 229 generates sterilizing ions, suppresses propagation
of floating fungi, and performs sterilization. Specifically, the sterilizing unit
229 ionizes air, generates positive ions and negative ions, takes in floating fungi
by means of the positive ions and the negative ions, and inactivates the floating
fungi.
[0237] In addition, in the deodorizing duct 226 shown in FIG. 16, a filter 234 capable of
moving forward and rearward is installed on the upstream side of the deodorizing cartridge
228. The filter 234 is configured to be capable of collecting dust such as foreign
substances, that is, fine particles and the like flowing in together with air through
the suction port 219. The filter 234 is attachable and detachable through the wide-width
portion 221 in a state where the shutter 222 is removed.
[0238] The deodorizing unit 213 having the deodorizing duct 226 configuring the deodorizing
flow channel and the deodorizing cartridge 228 are installed in the convex portion
223 of the base 211 and is installed on a side lower than the reference plane L. The
wide-width portion 221 includes the suction port 219 and the discharge port 220. The
wide-width portion 221 protrudes from the convex portion 223 in the middle of the
base 211 on the tip end side and faces the inside of the opening 210a of the toilet
bowl 210. In addition, the fan 227 and the sterilizing unit 229 are installed on a
side upper than a reference plane 2L.
[0239] In addition, the suction port 219 formed in the wide-width portion 221 of the base
211 is open to a side lower than the upper surface 210b of the toilet bowl 210, that
is, a side lower than the reference plane 2L. A part of the discharge port 220 formed
in the wide-width portion 221 of the base 211 is open to a side lower than the reference
plane. It is preferable that at least a part of the upper discharge port 220a is positioned
on a side lower than the reference plane 2L in the discharge port 220.
[0240] In regard to suctioning of air through the suction port 219 in the deodorizing unit
213, deodorization is performed by suctioning stagnant air including an odor in the
lower portion of the toilet bowl 210 into the deodorizing duct 226. Air to be discharged
through the discharge port 220 after deodorization is discharged in a substantially
horizontal direction, swirls along the rim water passage 225 in the toilet bowl 210
and is guided to the suction port 219 again.
[0241] Therefore, the deodorizing flow channel in the deodorizing duct 226 and the swirl
flow channel of air in the toilet bowl 210 form a circulation flow channel in which
air circulates repetitively. In the private part washing device 23 shown in FIG. 13,
the nozzle unit 212 is installed in the upper portions of the deodorizing duct 226
and the deodorizing cartridge 228 in the deodorizing unit 213 in an oblique direction.
[0242] In addition, the warm air drying unit 214 is installed at a position adjacent to
the deodorizing unit 213.
[0243] The warm air drying unit 214 includes a warm air generating device 235 and a warm
air duct 238. The warm air generating device 235 includes an air blowing fan 236 and
a heater 237. The air blowing fan 236 is provided on the upstream side of the warm
air duct 238. The heater 237 is arranged in the warm air duct 238. The warm air duct
238 communicates with a warm air blowing port formed in the upper portion of the suction
port 219 for air formed in the wide-width portion 221.
[0244] The warm air drying unit 214 has a configuration in which warm air of the warm air
generating device 235 warmed by the heater 237 flows through the warm air duct 238
and is discharged through a warm air blowing port 241. Accordingly, a private part
is dried. The warm air drying unit 214 may be configured to communicate with the discharge
port 220 of the wide-width portion 221 such that generated warm air is discharged
through thereof.
[0245] The deodorizing unit 213 of the toilet 21 according to the present embodiment B1
has a configuration as described above. Next, a deodorizing method performed by the
deodorizing unit 213 will be described.
[0246] At the time of deodorizing the toilet 21, the shutter 222 is in a downwardly open
state by causing the second washing nozzle 217 to protrude downward. Thereafter, the
first washing nozzle 216 is driven to protrude obliquely downward via the opening
portions 218 of the wide-width portion 221 so that the first washing nozzle 216 protrudes
beyond the shutter 222, and the fan 227 of the deodorizing unit 213 is driven. In
this case, since the shutter 222 is in a downwardly open state in which the inner
surface is directed downward, an air flow including an odor is regulated to flow in
through the suction port 219 without going upward.
[0247] The deodorizing duct 226 and the deodorizing cartridge 228 of the deodorizing unit
213 are installed in the convex portion 223 directed downward from the base 211 and
are positioned on a side lower than the reference plane 2L together with the suction
port 219. A part of the discharge port 220 is positioned on a side lower than the
reference plane 2L. In addition, air discharged through the discharge port 220 due
to the driven fan 227 is set such that the air is discharged in the horizontal direction
toward the rim water passage 225 formed in the upper portion on the inner surface.
[0248] As shown in FIG. 18, air discharged through the upper discharge port 220a of the
discharge port 220 at the time of deodorization laterally swirls as a swirl flow along
the rim water passage 225 in the toilet bowl 210 and returns to the private part washing
device 23 side. That is, a swirl flow channel is formed in the toilet bowl 210 as
indicated with the dotted line. Meanwhile, air discharged through the lower discharge
port 220b of the discharge port 220 is discharged as a traversal flow traversing toward
the middle part in the opening 210a of the toilet bowl 210, joins a swirl flow from
the upper discharge port 220a on the inner side surface of the toilet bowl 210 facing
the discharge port 220, forms a swirl flow, and is then headed for the suction port
219. Accordingly, an odor in the toilet bowl 210 can be thoroughly collected.
[0249] The suction port 219 is positioned in the lower portion of the reference plane 2L.
Therefore, air swirling in the toilet bowl 210 entangles a stagnant odor in the toilet
bowl 210 and is directly guided to the suction port 219. An air flow including an
odor flows in the deodorizing duct 226 due to sucking force of the fan 227 in the
deodorizing unit 213.
[0250] As shown in FIG. 16, most of air flowing in the deodorizing duct 226 and including
an odor flows in the deodorizing portion 231 covered with the cover member 232 in
the deodorizing cartridge 228, so that the odor is adsorbed and the air receives flow
resistance. In addition, a part of the air flows in the bypass passage configured
by the cutout portion 233 of the deodorizing cartridge 228, so that the part of the
air flows to the downstream side at a high speed without receiving flow resistance
by the deodorizing cartridge 228.
[0251] Accordingly, it is possible to increase the air speed of the entire air flow flowing
into the deodorizing duct 226 through the suction port 219. Therefore, it is possible
to increase the circulation speed of air which can be deodorized by the deodorizing
cartridge 228 in the deodorizing duct 226, and it is also possible to increase the
discharge flow rate of air through the discharge port 220. As a result, a swirl flow
in the rim water passage 225 of the toilet bowl 210 can also be increased in speed.
[0252] In this manner, the circulation flow speed of air in the deodorizing duct 226 in
the deodorizing unit 213 and the swirl flow speed in the rim water passage 225 of
the toilet bowl 210 can be increased, an odor can be deodorized faster by the deodorizing
cartridge 228, and the ventilation rate of odors in the toilet 21 and the water closet
space around thereof can be improved.
[0253] In a case of deodorizing the entire water closet space, it is possible to perform
deodorization around the toilet 21 by causing the toilet lid 28 to be in an open state
and causing the shutter 222 to be in an upward open state such that its inner surface
is directed upward.
[0254] As described above, in the deodorizing unit 213 of the toilet 21 according to the
present embodiment B1, since the bypass passage configured by the cutout portion 233
is formed in a part of the deodorizing cartridge 228, the flow rate of air flowing
in the suction port 219 and the discharge port 220 increases so that the air circulates
at a high speed. Therefore, it is possible to improve adsorption efficiency of an
odor in the deodorizing cartridge 228.
[0255] In addition, the air flow speed and the air volume in the deodorizing duct 226 can
be increased. Therefore, it is possible to improve the ventilation efficiency not
only in the toilet bowl 210 but also in the water closet space around the toilet bowl
210.
[0256] Furthermore, air resistance of the deodorizing cartridge 228 in the deodorizing unit
213 is reduced. Therefore, it is possible to efficiently perform deodorization even
if the mesh size of the deodorizing portion 231 is reduced or the deodorizing cartridge
228 is miniaturized.
[0257] In addition, the suction port 219, the discharge port 220, and the deodorizing duct
226 of the deodorizing unit 213 are positioned in the concave portion 224 of the toilet
bowl 210. Therefore, it is possible to efficiently collect an odor and to carry out
ventilation by causing a stagnant odor in the toilet bowl 210 to flow in together
with air at a high speed through the suction port 219 and adsorbing the odor by the
deodorizing cartridge 228.
[0258] The deodorizing unit 213 of the toilet 21 according to the present invention is not
limited to the embodiment B1 described above, and suitable changes, replacements,
and the like can be made within a range not departing from the gist of the present
invention. Hereinafter, modification examples and the like of the present invention
will be described. However, the same reference signs are used for components, members,
and the like which are the same as or similar to those described in the embodiment
B1, and descriptions thereof are omitted.
[0259] For example, in the deodorizing unit 213 described above, the bypass passage is realized
by forming the cutout portion 233 made by cutting off a part of the cover member 232
which covers the deodorizing portion 231 of the deodorizing cartridge 228. However,
the present invention is not limited to such a configuration. For example, in place
of the cutout portion 233 formed in the cover member 232 of the deodorizing cartridge
228, a tubular or hollow passage may be formed in the deodorizing portion 231 or the
cover member 232. Otherwise, without cutting off the deodorizing cartridge 228, a
bypass passage for an air flow may be formed outside the deodorizing cartridge 228
in a manner of being bifurcated from the deodorizing duct 226 in front of or behind
the deodorizing cartridge 228 and being isolated.
[0260] Even in these cases, the air speed of an air flow in front of or behind the deodorizing
cartridge 228 increases, and the air flow speed and the flow rate passing through
the suction port 219 and the discharge port 220 increase. Therefore, the air flow
speed and the flow rate passing through the inside of the deodorizing cartridge 228
increase, and efficiency of deodorizing and adsorbing an odor is improved.
[0261] In the embodiment B1 described above, in the deodorizing unit 213, the wide-width
portion 221 widened downward in width and the convex portion 223 protruding downward
are formed in a middle portion of the base 211 on the tip end side. The deodorizing
duct 226 and the deodorizing cartridge 228 are installed in the convex portion 223
and are arranged in the concave portion 224 at a level equal to or lower than the
reference plane 2L. On the other hand, the deodorizing duct 226, and the suction port
219 and the discharge port 220 interlinked therewith are not necessarily installed
at a level equal to or lower than the reference plane 2L.
[0262] For example, the embodiment B1 may employ a configuration in which a part of each
of the suction port 219, the discharge port 220, the deodorizing duct 226, and the
deodorizing cartridge 228 is installed at a level equal to or lower than the reference
plane L. Otherwise, the base 211 may be formed to have a flat plate shape in its entirety,
and the deodorizing unit 213 may be installed on this base 211, that is, above the
reference plane 2L.
[0263] In addition, in the embodiment B1, the deodorizing cartridge 228 is formed with the
deodorizing portion 231 and the cover member 232. However, the cover member 232 does
not have to be provided in the deodorizing cartridge 228, and the deodorizing portion
231 may be directly installed in the deodorizing duct 226 with no gap.
[0264] In the embodiment B1, the discharge port 220 is divided into the upper discharge
port 220a and the lower discharge port 220b, so that the discharging direction of
air is split into two. However, any one discharge port may be employed. In this case,
it is preferable that air flows along the rim water passage 225.
[0265] The deodorizer is not limited to the deodorizing cartridge 228. It is not necessary
to mention that various types of deodorizers can be installed as a deodorizer such
as a non-cartridge-type deodorizer and a mount-type deodorizer with respect to the
deodorizing duct 226. In addition, the deodorizing unit 213 configures the deodorizing
device.
[0266] In addition, the embodiment B1 may be combined with the configuration disclosed in
at least one of the embodiments A1 to A3, or the configuration of at least one of
the embodiments A1 to A3 and the configuration of a modification example may be applied
suitably and selectively.
[0267] Next, a deodorizing device of a flushing-type toilet (toilet) according to an embodiment
C1 of the present invention will be described based on the accompanying drawings.
[0268] FIGS. 19 to 26 illustrate a deodorizing unit 313 as a deodorizing device of a flushing-type
toilet 31 according to the embodiment of the present invention.
[0269] FIGS. 19 and 20 illustrate the flushing-type toilet 31 including a private part washing
device 33 of the embodiment. The toilet 31 includes the private part washing device
33 in the rear portion on the upper surface of a toilet main body 32. The private
part washing device 33 is included in a case 35 housing various functional components
for private part washing, warm air drying, and deodorizing. A toilet seat 37 and a
valve lid 38 installed on the toilet main body 32 are attached to a cover 36 provided
in the case 35 so as to be capable of being individually opened and closed.
[0270] In FIG. 20, the toilet main body 32 has a toilet bowl 310 receiving filth, and a
drain pipe portion (not shown). The drain pipe portion extends downward from a bottom
portion of the toilet bowl 310. A rim water passage 325, a drop flow channel, and
the like are formed in an upper inner wall in the toilet bowl 310. The rim water passage
325 is formed in order to generate a swirl flow of washing water. The drop flow channel
is formed in order to form a flow for dropping a swirl flow toward the drain pipe
portion.
[0271] The private part washing device 33 is installed on a base 311 arranged in the rear
portion on an upper surface 310b forming an opening 310a of the toilet bowl 310. The
private part washing device 33 includes a nozzle unit 312, the deodorizing unit 313,
a warm air drying unit 314, and the like. The nozzle unit 312 includes a private part
washing nozzle (described below). The deodorizing unit 313 is provided in order to
deodorize an odor generated in the toilet bowl 310. The warm air drying unit 314 is
provided in order to dry a private part after washing with warm air. Furthermore,
the private part washing device 33 includes a warm water supply unit 315, a control
unit, a power supply board, and the like. The warm water supply unit 315 is provided
in order to supply warm water to the nozzle unit 312. The control unit is provided
in order to control driving of each of the units.
[0272] In the private part washing device 33 shown in FIGS. 20 and 21, the nozzle unit 312
is installed in the middle of the base 311 on a tip end side facing the opening 310a
of the toilet bowl 310 in the toilet main body 32. In the nozzle unit 312, as a pair
of private part washing nozzles, a first washing nozzle 316 and a second washing nozzle
317 are arranged in parallel and are installed obliquely downward. The first washing
nozzle 316 is a nozzle for anus washing, and the second washing nozzle 317 is a washing
nozzle for bidet. Each of the first and second washing nozzles 316 and 317 has a discharging
hole for discharging washing water, in the tip end portion positioned below.
[0273] The first and second washing nozzles 316 and 317 are interlinked with the warm water
supply unit 315 installed in the base 311, via piping. The warm water supply unit
315 selectively supplies warm water, which has been adjusted to a set temperature,
to the first and second washing nozzles 316 and 317 upon a command of the control
unit (not shown).
[0274] In addition, as shown in FIGS. 21, 23A, and 23B, a wide-width portion 321 extending
downward and having a wide width is provided in the middle of the base 311 on the
front surface facing the opening 310a of the toilet bowl 310. A pair of opening portions
318 is provided in the middle of the wide-width portion 321. The first and second
washing nozzles 316 and 317 can respectively protrude forward through the opening
portions 318 of the wide-width portion 321. A suction port 319 for sucking air including
an odor and a discharge port 320 for discharging deodorized air are formed on both
sides of the pair of opening portions 318 in the wide-width portion 321.
[0275] In addition, a shutter 322 for conducting an opening-closing operation over the pair
of opening portions 318, and the suction port 319 and the discharge port 320 on the
right and left sides of the pair of opening portions 318 is provided on the front
surface side of the wide-width portion 321 (refer to FIG. 21). The shutter 322 exhibits
a substantially rectangular plate shape. The shutter 322 is held such that its rear
surface is pulled to the wide-width portion 321 side by a spring housed in a tube
portion (not shown). The shutter 322 is configured to be pivotable upward and downward
by the first washing nozzle 316 and the second washing nozzle 317.
[0276] That is, in a case where the first washing nozzle 316 protrudes downward, one projection
portion (not shown) formed on the rear surface of the shutter 322 is pushed and the
inner surface of the shutter 322 pivots upward, so that the shutter 322 is in an upwardly
open state. In a case where the second washing nozzle 317 protrudes downward, the
other projection portion (not shown) formed on the rear surface of the shutter 322
is pushed and the inner surface of the shutter 322 pivots downward, so that the shutter
322 is in a downwardly open state.
[0277] At the time of washing by the first washing nozzle 316, the second washing nozzle
317 protrudes downward and the shutter 322 is in a downwardly open state. Then, in
a state where the first washing nozzle 316 has moved forward beyond the shutter 322,
washing is performed by the first washing nozzle 316. In addition, in a case where
washing is performed by the second washing nozzle 317, the second washing nozzle 317
protrudes downward and the shutter 322 is in a downwardly open state. Furthermore,
in a state where the second washing nozzle 317 has moved forward beyond the shutter
322, washing is performed.
[0278] In addition, the base 311 for mounting the private part washing device 33 has a substantially
flat plate shape. However, a convex portion 323 which has a predetermined range and
a convex curve shape forming a convexity downward throughout a part from the wide-width
portion 321 to the tip end side of the base 311 is formed in the middle of its tip
end side. Therefore, a concave recess portion 323a is formed on the upper surface
side of the convex portion 323.
[0279] Meanwhile, in the toilet main body 32 shown in FIG. 22, the upper surface 310b of
the toilet bowl 310 has a flat surface shape. On the upper surface 310b of the toilet
bowl 310, a concave portion 324, which is recessed downward by a predetermined range,
is formed in a circumferential edge portion of a mount portion 310c for mounting the
base 311 facing the opening 310a. When the base 311 is installed on the mount portion
310c of the toilet bowl 310, the convex portion 323 of the base 311 sits on the concave
portion 324, and the concave portion 324 and the convex portion 323 are fitted together.
[0280] In FIGS. 23A and 23B, the mount portion 310c of the toilet main body 32 is included
in the upper surface 310b and forms the same plane. This plane is indicated as a reference
plane 3L called "ceramic zero surface". Moreover, in the wide-width portion 321 of
the base 311, the pair of opening portions 318 through which the first and second
washing nozzles 316 and 317 penetrate and move forward and rearward, and the suction
port 319 and the discharge port 320 on both sides thereof are positioned on a side
lower than the reference plane L in their entirety or a part of height portions.
[0281] FIG. 23A shows the wide-width portion 321 excluding a frame portion which has the
pair of opening portions 318. FIG. 23B shows a state where the frame portion of the
opening portions 318 is installed in the wide-width portion 321. In the example shown
in FIGS. 23A and 23B, the suction port 319 is at a level equal to or lower than the
reference plane 3L in its entirety, and the discharge port 320 is at a level equal
to or lower than the reference plane 3L except for a part.
[0282] In addition, in the opening 310a of the toilet bowl 310 shown in FIG. 22, the rim
water passage 325 is formed along a lower circumferential surface of the circumferential
edge portion of the upper surface 310b. The rim water passage 325 is a grooved rim-shaped
passage formed to circle around along an inner side surface of the toilet bowl 310.
The rim water passage 325 generates a swirl flow of washing water for washing the
toilet bowl 310.
[0283] As shown in FIGS. 21 and 25, in the concave recess portion 323a on the upper surface
of the convex portion 323 in the middle of the base 311 on the tip end side, the deodorizing
unit 313 is installed on a side lower than the nozzle unit 312. As shown in FIG. 24,
the deodorizing unit 313 includes a deodorizing duct 326, a fan 327, a deodorizing
cartridge 328, and a sterilizing unit 329. The suction port 319 and the discharge
port 320 formed in the wide-width portion 321 are interlinked with each other through
the deodorizing duct 326. For example, the deodorizing duct 326 is formed to have
a substantially U-shape or a substantially laid U-shape. The fan 327 is provided in
the middle of the deodorizing duct 326 as an air blower. The deodorizing cartridge
32 is a deodorizer and is installed on the upstream side of the fan 327. The sterilizing
unit 329 is installed on the downstream side of the fan 327.
[0284] The deodorizing duct 326 is a passage of an air flow configuring a deodorizing flow
channel. In the deodorizing duct 326, the suction port 319 provided at its upstream
end faces the opening 310a of the toilet bowl 310 and suctions air including an odor.
[0285] In FIG. 24, the deodorizing cartridge 328 is installed in the middle part of the
flow channel of the deodorizing duct 326 of the deodorizing unit 313. The deodorizing
cartridge 328 is internally equipped with the deodorizing catalyst and includes a
deodorizing portion 331 which eliminates an odor included in passing air. In the present
embodiment, the deodorizing cartridge 328 includes the deodorizing portion 331 and
a cover member 332. The deodorizing portion 331 is an adsorption-type deodorant having
activated carbon or the like as a catalyst. The cover member 332 covers an outer circumferential
surface of the deodorizing portion 331 and is formed to be a thin layer constituted
of a sponge, for example, having waterproof property and elastic property.
[0286] The deodorizing portion 331 internally houses a deodorant such as activated carbon.
Otherwise, a decomposition-type deodorant may be employed as a deodorant of a different
type such as a photocatalyst having a function of decomposing a substance by emitting
an ultraviolet ray. The deodorizing portion 331 has the outer circumferential surface
or the inner surface formed in a meshed state in order to ensure ventilation. For
example, the sponge of the cover member 332 is a closed-cell-type belt-like member
having high waterproof property and is wound around the side surface of the deodorizing
portion 331.
[0287] Moreover, the deodorizing cartridge 328 has a cutout portion 333 formed by cutting
off a part of the cover member 332, for example, a part of the deodorizing portion
331 on the upper surface side. Otherwise, the cutout portion 333 may be formed on
the side surface or the bottom surface of the cover member 332. The cutout portion
333 configures a bypass passage in which inflow air bypasses the deodorizing portion
331 and flows to the downstream side. The cutout portion 333 is formed by cutting
off the cover member 332 along the air flow direction as much as a predetermined range
of the thickness.
[0288] Therefore, most of air flowing in the deodorizing duct 326 passes through the deodorizing
portion 331 and is deodorized by the deodorizing cartridge 28. Then, a part thereof
passes through the bypass passage of the cutout portion 333 and flows to the downstream
side. Since a part of air flowing in the deodorizing cartridge 28 passes through the
bypass passage of the cutout portion 333, ventilation property of the deodorizing
cartridge 328 is improved. As a result, it is possible to increase the air speed and
the air volume of air flowing in through the suction port 319 and flowing in the deodorizing
duct 326.
[0289] Otherwise, the entire quantity of an air flow may pass through the deodorizing portion
331 or the cover member 332 of the deodorizing cartridge 328 without providing a bypass
passage such as the cutout portion 333 in the deodorizing cartridge 328.
[0290] In addition, the sterilizing unit 329 generates sterilizing ions, suppresses propagation
of floating fungi, and performs sterilization. Specifically, the sterilizing unit
329 ionizes air, generates positive ions and negative ions, takes in floating fungi
by means of the positive ions and the negative ions, and inactivates the floating
fungi.
[0291] In addition, in the deodorizing duct 326 shown in FIG. 24, an attachable/detachable
filter 334 is installed on the upstream side of the deodorizing cartridge 328. The
filter 334 is configured to be capable of collecting dust such as foreign substances,
that is, fine particles and the like flowing in together with air through the suction
port 319. The filter 334 is attachable and detachable through the wide-width portion
321 in a state where the shutter 322 is removed.
[0292] The deodorizing unit 313 having the deodorizing duct 326 configuring the deodorizing
flow channel and the deodorizing cartridge 328 are installed in the concave recess
portion 323a on the upper surface of the convex portion 323 of the base 311 and is
installed on a side lower than the reference plane 3L. The fan 327 and the sterilizing
unit 329 are installed on a side upper than the reference plane 3L.
[0293] In regard to suctioning of air through the suction port 319 in the deodorizing unit
313, deodorization is performed by suctioning stagnant air including an odor in the
lower portion of the toilet bowl 310 into the deodorizing duct 326. Air to be discharged
through the discharge port 320 is discharged in a substantially horizontal direction,
swirls in a substantially horizontal direction along the rim water passage 325 in
the toilet bowl 310, and is guided to the suction port 319 again.
[0294] Therefore, the deodorizing flow channel in the deodorizing duct 326 and the swirl
flow channel of air in the toilet bowl 310 form a circulation flow channel in which
air circulates repetitively. In the private part washing device 33 shown in FIGS.
21 and 25, the nozzle unit 312 is installed in the upper portions of the deodorizing
duct 326 and the deodorizing cartridge 328 in the deodorizing unit 313.
[0295] In FIG. 21, the warm air drying unit 314 is installed at a position adjacent to the
deodorizing unit 313. The warm air drying unit 314 includes a warm air generating
device 335 and the warm air duct 338. The warm air generating device 335 includes
an air blowing fan 336 and a heater 337. The air blowing fan 336 is provided on the
upstream side of the warm air duct 338. The heater 337 is arranged in the warm air
duct 338. The warm air duct 338 communicates with a warm air blowing port 341 formed
in the upper portion of the suction port 319 for air formed in the wide-width portion
321 (refer to FIG. 23B).
[0296] The warm air drying unit 314 has a configuration in which warm air of the warm air
generating device 335 warmed by the heater 337 flows through the warm air duct 338
and is discharged through the warm air blowing port 341. Accordingly, a private part
is dried. The warm air drying unit 314 may communicate with the discharge port 320
such that generated warm air is discharged via the warm air duct 338. Otherwise, the
discharge port 320 may be formed as a discharge port of the warm air duct 338.
[0297] The deodorizing unit 313 of the toilet 21 according to the present embodiment C1
has a configuration as described above. Next, a deodorizing method performed by the
deodorizing unit 313 will be described.
[0298] At the time of deodorizing the toilet 31, the shutter 322 is in a downwardly open
state by causing the second washing nozzle 317 to protrude downward. Thereafter, the
first washing nozzle 216 is driven to protrude obliquely downward via the opening
portions 318 of the wide-width portion 321 so that the first washing nozzle 216 protrudes
beyond the shutter 322, and the fan 327 of the deodorizing unit 313 is driven. In
this case, since the shutter 322 is in a downwardly open state in which the inner
surface is directed downward, an air flow including an odor is regulated to flow in
through the suction port 319 without going upward.
[0299] The deodorizing duct 326 and the deodorizing cartridge 328 of the deodorizing unit
313 are installed in the concave recess portion 323a on the upper surface of the convex
portion 323 of the base 311 and are positioned on a side lower than the reference
plane 3L together with the suction port 319. A part of the discharge port 320 is positioned
on a side lower than the reference plane 3L. Air discharged through the discharge
port 220 due to the driven fan 327 is set such that the air is discharged in the horizontal
direction toward the rim water passage 325 formed in the upper portion on the inner
surface.
[0300] Therefore, as shown in FIG. 26, air discharged through the discharge port 320 in
the horizontal direction at the time of deodorization laterally swirls along the rim
water passage 325 in the toilet bowl 310 and returns to the private part washing device
33 side. That is, a swirl flow channel is formed in the toilet bowl 310 as indicated
with the dotted line. The suction port 319 is positioned in the lower portion of the
reference plane 3L. Therefore, air horizontally swirling in the toilet bowl 310 entangles
a stagnant odor in the toilet bowl 310 and is directly guided to the suction port
319 without being displaced in the upward/downward direction. An air flow including
an odor flows in the deodorizing duct 326 due to sucking force of the fan 327 in the
deodorizing unit 313.
[0301] As shown in FIG. 24, most of air flowing in the deodorizing duct 326 and including
an odor flows in the deodorizing portion 331 covered with the cover member 332 in
the deodorizing cartridge 328, so that the odor is adsorbed. In addition, a part of
the air flows in the bypass passage constituted of the cutout portion 333 of the deodorizing
cartridge 328, so that the part of the air flows to the downstream side at a high
speed without receiving flow resistance by the deodorizing cartridge 328.
[0302] Accordingly, it is possible to increase the air speed of the entire air flow flowing
into the deodorizing duct 326 through the suction port 319. Therefore, it is possible
to increase the circulation speed of air which can be deodorized by the deodorizing
cartridge 328 in the deodorizing duct 326, and it is also possible to increase the
discharge flow rate of air through the discharge port 320. As a result, a swirl flow
in the rim water passage 325 in the toilet bowl 310 can also be increased in speed.
[0303] In a case where the bypass passage of the cutout portion 333 is not provided in the
deodorizing cartridge 328, the entire quantity of an air flow passes through the deodorizing
portion 231 or the cover member 332, thereby being deodorized.
[0304] In this manner, the circulation flow speed of air in the deodorizing duct 326 in
the deodorizing unit 313 and the swirl flow speed along the rim water passage 325
in the toilet bowl 310 can be increased, an odor can be deodorized faster by the deodorizing
cartridge 328, and the ventilation rate of odors in the toilet 31 and the water closet
space around thereof can be improved.
[0305] As described above, in the deodorizing unit 313 of the toilet 31 according to the
present embodiment C1, the deodorizing duct 326 and the deodorizing cartridge 328
are installed in the concave recess portion 323a of the convex portion 323 protruding
downward from the base 311 and are positioned on a side lower than the reference plane
3L. The suction port 319 and a part of the discharge port 320 are also positioned
on a side lower than the reference plane 3L. Therefore, an air flow discharged through
the discharge port 320 flows out in the horizontal direction and swirls along the
rim water passage 325 in the opening 310a of the toilet bowl 310. Thus, it is possible
to improve the circulation speed and efficiency of an air flow.
[0306] Moreover, an air flow discharged through the discharge port 320 entangles a stagnant
odor in the toilet bowl 310 and is directly guided to the suction port 319 without
being displaced in the upward/downward direction. Accordingly, a pressure loss of
the air flow can be reduced and performance of suctioning an odor can be improved.
[0307] An air flow swirling in the toilet bowl 310 along the rim water passage 325 in the
opening 310a efficiently entangles a stagnant odor in the toilet bowl 310 and flows
into the suction port 319 of the deodorizing unit 313, thereby circulating. Therefore,
an odor in the toilet bowl 310 can be efficiently collected by the deodorizing cartridge
328, and leakage of an odor can be reduced.
[0308] Furthermore, in the present embodiment C1, since the deodorizing duct 326 and the
deodorizing cartridge 328 configuring the deodorizing flow channel of the deodorizing
unit 313 is installed in the concave recess portion 323a of the base 311 and the convex
portion 323 protruding downward is installed in the concave portion 324 on the upper
surface 310b of the toilet bowl 310, the deodorizing flow channel can be shortened.
Moreover, since the nozzle unit 312 is installed on the upper portion of the deodorizing
duct 326, the private part washing device 33 can be miniature, thereby contributing
to space saving.
[0309] In addition, since the bypass passage of the cutout portion 333 is provided in the
deodorizing cartridge 328 of the deodorizing unit 313, the air speed and the air volume
in the deodorizing duct 326 can be increased. In this regard as well, deodorizing
efficiency can be improved.
[0310] The flushing-type toilet 31 including the deodorizing unit 313 according to the present
invention is not limited to the embodiment C1 described above, and suitable changes,
replacements, and the like can be made within a range not departing from the gist
of the present invention. Hereinafter, modification examples and the like of the present
invention will be described. However, the same reference signs are used for components,
members, and the like which are the same as or similar to those described in the embodiment
C1, and descriptions thereof are omitted.
[0311] For example, in the embodiment C1 described above, a part of the discharge port 320
provided in the wide-width portion 321 is installed on a side lower than the reference
plane L. However, similar to the suction port 319, its entirety may be positioned
on a side lower than the reference plane 3L. In this case, it is possible to further
horizontally discharge air on the rim water passage 325 in the toilet bowl 310 through
the discharge port 320. Therefore, discharging air flowing in the circulation flow
channel can more smoothly circulate to the suction port 319.
[0312] Otherwise, a part of each of the deodorizing duct 326, the deodorizing cartridge
328, and the suction port 319 may be installed on a side lower than the reference
plane L. In this case as well, a part of a discharging air flow of air at the discharge
port 320 or a suctioning air flow of air including an odor at the suction port 319
is horizontal and the inclined angle of the remaining part is small. Therefore, it
is possible to improve circulation efficiency of an air flow in the toilet bowl 310
and to improve suctioning of an odor and deodorizing efficiency, compared to technologies
in the related art.
[0313] In addition, in the embodiment C1 described above, the discharge port 320 is configured
to be a discharge port formed in the deodorizing flow channel. However, in place thereof,
for example, the discharge port 320 may be configured to be a discharge port for a
different member such as a discharge port of the warm air duct 338 of the warm air
drying unit 314.
[0314] In addition, the embodiment C1 may be combined with the configuration disclosed in
at least one of the embodiments A1 to A3 and B1, or the configuration of at least
one of the embodiments A1 to A3 and B1 and the configuration of a modification example
may be applied suitably and selectively.
[0315] Next, a toilet stool according to an embodiment D1 of the present invention will

441a of the body portion 441. As shown in FIG. 27, in the toilet seat 44, a part in
the vicinity of a rear end portion 441b in a laid posture is attached to the toilet
main body 42 via the functional section 43. The toilet seat 44 is configured to be
pivotable about a pivot axis 443 extending in the width direction in the vicinity
of the rear end portion 441b.
[0320] As shown in FIG. 29, the four protruding portions 442 are arranged in a manner of
two each at an interval in the width direction and two each at an interval in the
forward/rearward direction in a laid posture. As shown in FIG. 27, when the toilet

445 (substantially horizontal surface) is formed on the front side of the inclination
portion 444 of the body portion 441 in a laid posture. The inclination portion 444
and the horizontal portion 445 are connected to each other at a corner portion 446.
[0322] As shown in FIG. 27, the toilet lid 45 is formed to have a shape covering an upper
surface 441c and side surfaces 441d of the body portion 441 of the toilet seat 44
in a laid posture. The state where the toilet lid 45 covers the toilet seat 44 will
be referred to as a state where the toilet lid 45 is closed, and a state where the
toilet seat 44 is exposed will be referred to as a state where the toilet lid 45 is
opened.
[0323] In the toilet lid 45, a part in the vicinity of a lower end portion 45a in an opened
state (rear end portion in a closed state) is attached to the rear portion side of
the toilet main body 42 via the functional section 43. The toilet lid 45 is configured
to pivotable about a pivot axis 451 extending in the width direction in the vicinity
of the lower end portion 45a.
[0324] In a state where the toilet lid 45 is closed, the lower end portion of the toilet
lid 45 and the upper surface 42a of the toilet main body 42 are separated from each
other.
[0325] In the present embodiment D1, the toilet lid 45 is configured to be capable of being
manually opened and closed by a user and to be capable of being automatically opened
and closed in accordance with control of the control unit.
[0326] As shown in FIG. 30, the private part washing device 46 has a nozzle unit 461, a
warm water supply unit 462, and a warm air drying unit 463. The nozzle unit 461 has
a pair of private part washing nozzles 4611 and 4612. The warm water supply unit 462
is provided in order to supply warm water to the nozzle unit 461. The warm air drying
unit 463 is driven at the time of warm air drying.
[0327] The nozzle unit 461 is arranged in a substantial middle portion of the functional
section 43 in the width direction. In the pair of private part washing nozzles 4611
and 4612, one is configured to serve as a first nozzle 4611 for anus washing and the
other is configured to serve as a second nozzle 4612 for bidet. The first nozzle 4611
and the second nozzle 4612 are adjacent to each other in the width direction. The
first nozzle 4611 is arranged on one side in the width direction and the second nozzle
4612 is arranged on the other side in the width direction.
[0328] Each of the first nozzle 4611 and the second nozzle 4612 is formed to have a shape
extending in an inclination direction gradually downward to the front. Each of the
first nozzle 4611 and the second nozzle 4612 is supported by a support portion 4613
provided in the case 49. The first nozzle 4611 and the second nozzle 4612 are supported

in the inclination direction gradually downward to the front. For example, the support
portion 4613 is configured to include a rack-and-pinion mechanism and a motor which
is connected to a pinion of the rack-and-pinion mechanism.
[0329] The inclination direction in which the first nozzle 4611 and the second nozzle 4612
extend and move forward and rearward will be referred to as a moving direction of
the nozzle. In the moving direction of the nozzle, a side to which the first nozzle
4611 and the second nozzle 4612 move forward to the front and the lower side will
be referred to as the front side, and a side to which the first nozzle 4611 and the
second nozzle 4612 move rearward to the rear and the upper side will be referred to
as the rear side.
[0330] On a front surface 49a of the case 49, a first forward/rearward nozzle movement port
491a and a second forward/rearward nozzle movement port 491b are formed in a substantial
middle portion in the width direction, while being adjacent to each other in the width
direction. The first nozzle 4611 moving forward and rearward passes through the first
forward/rearward nozzle movement port 491a. The second nozzle 4612 moving forward
and rearward passes through the second forward/rearward nozzle movement port 491b.
[0331] In addition, a discharge port 491c and a suction port 491d are formed on the front
surface 49a of the case while being adjacent to one side of the first forward/rearward
nozzle movement port 491a in the width direction. The discharge port 491c is configured
to discharge warm air from the warm air drying unit 463. The suction port 491d is
provided in order to suction air into the deodorizing flow channel formed in the sterilizing/deodorizing
device 47. A discharge port 491e is formed on the front surface 49a of the case while
being adjacent to the other side of the second forward/rearward nozzle movement port
491b in the width direction. The discharge port 491e is configured to discharge air
for performing sterilization and deodorization by the sterilizing/deodorizing device
47. The first forward/rearward nozzle movement port 491a, the second forward/rearward
nozzle movement port 491b, the discharge port 491c of the warm air drying unit 463,
and the suction port 491d and the discharge port 491e of the sterilizing/deodorizing
device 47 are open obliquely downward from the functional section 43 side to the inside
of the toilet bowl 421.
[0332] On the front surface 49a of the case 49, a region in which the first forward/rearward
nozzle movement port 491a, the second forward/rearward nozzle movement port 491b,
the discharge port 491c of the warm air drying unit 463, and the suction port 491d
and the discharge port 491e of the sterilizing/deodorizing device 47 are formed will
be referred to as an opening forming portion 491.
[0333] A shutter 492 for the opening forming portion 491 switching between a covered state
(refer to FIG. 28) and an exposed state (refer to FIGS. 30 and 31) is provided on
the front surface 49a of the case 49. The shutter 492 is configured to be capable
of opening and closing the opening forming portion 491 in accordance with any one
of the first nozzle 4611 and the second nozzle 4612 moving forward and rearward.
[0334] The shutter 492 extends in the width direction and is formed to have a plate shape
having a size to the extent that the opening forming portion 491 of the case 49 can
be blocked. The shutter 492 is supported by a pair of support tools 493 and 493 provided
on the front surface 49a of the case 49. The pair of support tools 493 and 493 is
attached to a surface (surface on a side facing the opening forming portion 491 of
the case 49) 492a on the inner side of the shutter 492 at an interval in the width
direction. In the present embodiment D1, the shutter 492 is attached so as to be attachable
and detachable with respect to the pair of support tools 493 and 493. The pair of
support tools 493 and 493 supports the shutter 492 so as to be pivotable about the
pivot axis 494 extending in the width direction in an intermediate portion of the
shutter 492 in the height direction.
[0335] Two protrusion portions 495 and 496 are formed on the surface 492a on the inner side
of the shutter 492. One of the two protrusion portions 495 and 496 serves as a first
protrusion portion 495 and the other serves as a second protrusion portion 496. The
first protrusion portion 495 is formed at a position of facing the tip end portion
of the first nozzle 4611 in a state where the shutter 492 covers the opening forming
portion 491. In the first protrusion portion 495, the tip end portion is arranged
above a pivot axis 494. The second protrusion portion 496 is formed at a position
of facing the tip end portion of the second nozzle 4612 in a state where the shutter
492 covers the opening forming portion 491. In the second protrusion portion 496,
the tip end portion is arranged on a side lower than the pivot axis 494.
[0336] In a state where the shutter 492 covers the opening forming portion 491, when the
first nozzle 4611 moves to the front side in the moving direction of the nozzle, the
tip end portion of the first nozzle 4611 presses the shutter 492 to the front side
in a state of being abutting on the tip end portion of the first protrusion portion
495 on a side upper than the pivot axis 494. Accordingly, the shutter 492 pivots about
the pivot axis 494. As shown in FIG. 30, the shutter 492 is in a posture in which
a surface 492a on the inner side is directed in an obliquely upward direction to the
upper side and the rear side, and a surface 492b on the outer side is directed in
an obliquely downward direction to the lower side and the front side. The shutter
492 in this posture is in an opened state (upwardly lying open state) where the upper
side is open.
[0337] The shutter 492 in an upwardly open state is arranged below the first forward/rearward
nozzle movement port 491a, the second forward/rearward nozzle movement port 491b,
the discharge port 491c of the warm air drying unit 463, and the suction port 491d
and the discharge port 491e of the sterilizing/deodorizing device 47.
[0338] On the other hand, in a state where the shutter 492 covers the opening forming portion
491, when the second nozzle 4612 moves to the front side in the moving direction of
the nozzle, the tip end portion of the second nozzle 4612 presses the shutter 492
to the front side in a state of abutting on the tip end portion of the second protrusion
portion 496 on a side lower than the pivot axis 494. Accordingly, the shutter 492
pivots about the pivot axis 494. As shown in FIG. 31, the shutter 492 is in a posture
in which the surface 492a on the inner side is directed in an obliquely downward direction
to the lower side and the rear side, and the surface 492b on the outer side is directed
in an obliquely upward direction to the upper side and the front side. The shutter
492 in this posture is in an opened state (downwardly open state) where the lower
side is open.
[0339] The shutter 492 in a downwardly open state is arranged above the first forward/rearward
nozzle movement port 491a, the second forward/rearward nozzle movement port 491b,
the discharge port 491c of the warm air drying unit 463, and the suction port 491d
and the discharge port 491e of the sterilizing/deodorizing device 47.
[0340] In a case where washing is performed by the first nozzle 4611, the second nozzle
4612 moves to the front side in the moving direction of the nozzle such that the shutter
492 is in a downwardly open state, and then the first nozzle 4611 moves to the front
side. At this time, the tip end part of the first nozzle 4611 moves forward beyond
the shutter 492 from the lower side of the shutter 492. When the shutter 492 is in
a downwardly open state and the tip end part of the first nozzle 4611 is in a state
of being arranged on the front side of the shutter 492, washing is performed by the
first nozzle 4611.
[0341] In a case where washing is performed by the second nozzle 4612, the second nozzle
4612 moves to the front side in the moving direction of the nozzle such that the shutter
492 is in a downwardly open state. Furthermore, the second nozzle 4612 moves forward
in the moving direction of the nozzle. When the shutter 492 is in a downwardly open
state and the tip end part of the second nozzle 4612 is in a state of being arranged
on the front side of the shutter 492, washing is performed by the second nozzle 4612.
[0342] In this manner, washing is performed when the shutter 492 is in a downwardly open
state and the surface 492a on the inner side of the shutter 492 is in a state of being
directed downward. Therefore, there is a low possibility that a spray generated at
the time of washing adheres to the surface 492a on the inner side of the shutter 492.
As a result, when the shutter 492 is closed after washing, it is possible to prevent
or suppress a spray from entering the inside of the case 49.
[0343] As shown in FIG. 30, the sterilizing/deodorizing device 47 is arranged so as to surround
the nozzle unit 461 of the private part washing device 46 in a substantial middle
portion of the functional section 43 in the width direction. As shown in FIG. 32,
the sterilizing/deodorizing device 47 has a duct 471, a sterilizing/deodorizing fan
472, a deodorizing cartridge 473, and a sterilizing unit 474. The duct 471 is arranged
so as to surround the nozzle unit 461 (refer to FIG. 30). The fan 472 is provided
in the middle of the duct 471. The deodorizing cartridge 473 is arranged on the upstream
side of the fan 472. The sterilizing unit 474 is provided on the downstream side of
the fan 472. The duct 471 configures a deodorizing flow channel of the sterilizing/deodorizing
device 47.
[0344] The duct 471 is configured to suck air through the suction port 491d formed on the
front surface 49a of the opening forming portion 491 of the case 49 and to discharge
air, which has passed through the duct 471, to the outside through the discharge port
491e. In the present embodiment D1, the suction port 491d and the discharge port 491e
are arranged on the upper portion side of the toilet main body 42 and are open obliquely
downward to the inside of the toilet bowl 421. The duct 471 is configured to suction
air below the suction port 491d and discharge air, which has passed through the duct
471, to the front side through the discharge port 491e in a substantially horizontal
manner.
[0345] When the sterilizing/deodorizing device 47 is driven, if the shutter 492 is in an
upwardly open state as shown in FIG. 30, the shutter 492 is arranged below the suction
port 491d. Therefore, air below the shutter 492 is not suctioned to the duct 471 through
the suction port 491d, and air 4A1 above the shutter 492 (air above the toilet bowl
421) is suctioned to the duct 471 through the suction port 491d.
[0346] In addition, if the shutter 492 is in an upwardly open state, the shutter 492 is
arranged below the discharge port 491e. Therefore, air 4A2 discharged through the
discharge port 491e comes into contact with the surface 492a on the inner side of
the shutter 492 and is guided so as to be headed for the upper side. Accordingly,
in a case where the toilet lid 45 is opened, the air 4A2 discharged through the discharge
port 491e is released to a space above the toilet seat 44.
[0347] In this manner, in an upwardly open state, the shutter 492 configures a guide portion
which guides air above the toilet bowl 421 such that the air is introduced to the
suction port 491d and guides air discharged through the discharge port 491e such that
the air is directed upward from the toilet bowl 421. In FIG. 33, the bowl surface
in the toilet bowl 421 is indicated with the dotted line.
[0348] In addition, the shutter 492 in an upwardly open state is in a posture in which the
surface 492a on the inner side is directed in an obliquely upward direction to the
upper side and the rear side. Therefore, air above the toilet bowl 421 is likely to
be introduced to the suction port 491d along the surface 492a on the inner side of
the shutter 492, and air discharged through the discharge port 491e can be efficiently
guided so as to be directed upward from the toilet bowl 421 along the surface 492a
on the inner side of the shutter 492.
[0349] Furthermore, in the present embodiment D1, the surface 492a on the inner side of
the shutter 492 is formed into a curved surface on which an intermediate portion in
the height direction is recessed to the surface 492b side on the outer side from the
upper end portion and the lower end. Therefore, in the present embodiment D1, compared
to a case where the surface 492a on the inner side of the shutter 492 is formed into
a flat surface, air above the toilet bowl 421 is more likely to be introduced to the
suction port 491d along the surface 492a on the inner side of the shutter 492, and
air discharged through the discharge port 491e can be more efficiently guided so as
to be directed upward from the toilet bowl 421 along the surface 492a on the inner
side of the shutter 492.
[0350] On the other hand, if the shutter 492 is in a downwardly open state as shown in FIG.
31, the shutter 492 is arranged above the suction port 491d. Therefore, air in the
toilet bowl 421 below the shutter 492 is suctioned to the duct 471 through the suction
port 491d.
[0351] In addition, if the shutter 492 is in a downwardly open state, the shutter 492 is
arranged above the discharge port 491e. Therefore, air discharged through the discharge
port 491e is released to the inside of the toilet bowl 421 (refer to FIG. 28) in a
substantially horizontal direction to the front side, without coming into contact
with the shutter 492.
[0352] In this manner, when the shutter 492 is in a downwardly open state, air in the toilet
bowl 421 is suctioned through the suction port 491d, and air discharged through the
discharge port 491e is released to the inside of the toilet bowl 421.
[0353] In addition, in the present embodiment D1, when the shutter 492 is in a downwardly
open state, air in the toilet bowl 421 below the shutter 492 is more likely to be
suctioned through the suction port 491d than air above the shutter 492, and air discharged
through the discharge port 491e is more likely to be directed toward the inside of
the toilet bowl 421 below the shutter 492 than that above the shutter 492.
[0354] Air in the toilet bowl 421 may be introduced to the suction port 491d along the surface
492a on the inner side of the shutter 492 in a downwardly open state, and air discharged
through the discharge port 491e may be directed toward the inside of the toilet bowl
421 along the surface 492a on the inner side of the shutter 492.
[0355] The deodorizing cartridge 473 is internally equipped with a deodorizing catalyst
and has a function of eliminating an odor included in air passing through. As the
deodorizing cartridge 473, for example, an adsorption-type deodorant which employs
activated carbon or the like as a catalyst, or a decomposition-type deodorant such
as a photocatalyst which decomposes a substance by emitting a ray of light such as
an ultraviolet is used.
[0356] The sterilizing unit 474 has a function of generating sterilizing ions, suppressing
propagation of floating fungi, and performing sterilization. Specifically, the sterilizing
unit 474 ionizes air, generates positive ions and negative ions, surrounds floating
fungi by means of the positive ions and the negative ions, and inactivates the floating
fungi.
[0357] Such a sterilizing/deodorizing device 47 deodorizes air suctioned to the duct 471
through the suction port 491d by causing the air to pass through the deodorizing cartridge
473, generates positive ions and negative ions by using the sterilizing unit 474,
and discharges the air through the discharge port 491e.
[0358] As shown in FIG. 29, the illumination device 48 has LEDs 481 and 481 serving as a
pair of light sources respectively provided on both sides in the width direction of
the opening forming portion 491 on the front surface 49a of the case 49. The pair
of LEDs 481 and 481 is arranged at positions such that light can be emitted to the
inclination portion 444 of the body portion 441 of the toilet seat 44 in a lying state
as shown in FIG. 29, the corner portion 446, and the protruding portion 442 formed
on the rear portion side of the toilet seat 44.
[0359] As shown in FIG. 33, the pair of LEDs 481 and 481 is configured to emit light 4L
such that the light 4L comes into contact with each of the inclination portion 444
of the toilet seat 44 in a lying state, the corner portion 446, and the protruding
portion 442, is reflected so as to be headed for the inside of the toilet bowl 421,
and illuminates the inside of the toilet bowl 421.
[0360] In the present embodiment D1, when the water closet space 411 is sterilized and
deodorized by the sterilizing/deodorizing device 47, the illumination device 48 illuminates
the inside of the toilet bowl 421. In addition, as shown in FIG. 33, since the gap
d1 having a predetermined size is formed between the lower surface 441a of the body
portion 441 of the toilet seat 44 in a lying state and the upper surface 42a of the
toilet main body 42, light emitted to the inside of the toilet bowl 421 leaks out
through this gap 4d1. At this time, as shown in FIG. 34, if the toilet lid 45 is closed,
light which has leaked through the gap d1 between the toilet seat 44 and the upper
surface 42a of the toilet main body 42 leaks out of the toilet stool 41 through a
gap 4d2 having a predetermined size formed between the toilet lid 45 and the upper
surface 42a of the toilet main body 42. Therefore, even in a state where the toilet
lid 45 is closed, a user can visually recognize light illuminating the inside of the
toilet bowl 421 through the gap 4d2 between the toilet lid 45 and the upper surface
42a of the toilet main body 42.
[0361] In addition, first to third sensors (not shown) are provided in the toilet stool
41 according to the present embodiment D1. The first sensor detects that a user sits
on the toilet seat 44. The second sensor detects that a user is present in front of
the toilet stool 41. The third sensor detects that the toilet lid 45 is in an opened
state.
[0362] These first to third sensors are each configured to transmit a detection signal to
the control unit. In addition, a timer which can set a drive starting time and a driving
time period of the sterilizing/deodorizing device 47 is provided in the toilet stool
41 according to the present embodiment D1.
[0363] Subsequently, a method of sterilizing and deodorizing the water closet space 411
by the toilet stool 41 according to the present embodiment D1 will be described.
[0364] Control of performing sterilization and deodorization of the water closet space 411
will be referred to as control over sterilizing and deodorizing the water closet space
411, and control of stopping this control over sterilizing and deodorizing the water
closet space 411 will be referred to as control of stopping sterilizing and deodorizing
the water closet space 411.
[0365] First, when control over sterilizing and deodorizing the water closet space 411 starts,
the LEDs 481 and 481 of the illumination device 48 are lit, and the inside of the
toilet bowl 421 is illuminated.
[0366] Subsequently, the first nozzle 4611 moves forward and the shutter 492 is in an upwardly
open state.
[0367] Subsequently, the fan 472 of the sterilizing/deodorizing device 47 starts to be driven,
and the sterilizing unit 474 starts to be driven. Accordingly, air suctioned to the
duct 471 through the suction port 491d passes through the deodorizing cartridge 473
and is deodorized, and sterilizing ions generated by the sterilizing unit 474 are
released in the deodorized air. Then, air which is deodorized and in which sterilizing
ions are released is discharged through the discharge port 491e.
[0368] When the shutter 492 is in an upwardly open state, air above the toilet bowl 421
is introduced to the suction port 491d, and air which is discharged through the discharge
port 491e and performs sterilization and deodorization comes into contact with the
shutter 492 and is directed upward from the toilet bowl 421.
[0369] At this time, if the toilet lid 45 is in an opened state, air of the water closet
space 411 above the toilet seat 44 is suctioned to the duct 471 through the suction
port 491d. Air discharged through the discharge port 491e and performs sterilization
and deodorization is released to the water closet space 411 above the toilet seat
44 through the opening of the body portion 441 of the toilet seat 44.
[0370] On the other hand, if the toilet lid 45 is in a closed state, air below the toilet
lid 45 is suctioned to the duct 471 through the suction port 491d. Air discharged
through the discharge port 491e and performs sterilization and deodorization is released
to the water closet space 411 through the gap d1 having a predetermined size formed
between the toilet seat 44 and the upper surface 42a of the toilet main body 42, and
the gap 4d2 having a predetermined size formed between the toilet lid 45 and the upper
surface 42a of the toilet main body 42.
[0371] If control over sterilizing and deodorizing the water closet space 411 ends and control
of stopping sterilizing and deodorizing the water closet space 411 starts, the fan
472 of the sterilizing/deodorizing device 47 stops being driven, the sterilizing unit
474 stops being driven, and the sterilizing/deodorizing device 47 stops being driven.
[0372] Subsequently, the first nozzle 4611 moves rearward and the shutter 492 in an upwardly
open state is in a closed state.
[0373] Subsequently, the LEDs 481 and 481 of the illumination device 48 are turned off,
and the inside of the toilet bowl 421 is in a state of not being illuminated.
[0374] Accordingly, sterilization and deodorization of the water closet space 411 end.
[0375] In a case where the inside of the toilet bowl 421 is sterilized and deodorized, the
shutter 492 is in a downwardly open state. Accordingly, air in the toilet bowl 421
is introduced to the suction port 491d, and air which has passed through the duct
471 for performing sterilization and deodorization is discharged to the inside of
the toilet bowl 421 through the discharge port 491e without coming into contact with
the shutter 492. In the present embodiment D1, in a case where the inside of the toilet
bowl 421 is sterilized and deodorized, the LEDs 481 and 481 of the illumination device
48 are set not to be lit.
[0376] In addition, in a case where the water closet space 411 is sterilized and deodorized,
compared to a case where the inside of the toilet bowl 421 is sterilized and deodorized,
an output to the fan 472 is increased, and the suctioning quantity of air to the duct
471 and the discharging quantity of air from the duct 471 are increased. Accordingly,
it is possible to efficiently perform sterilization and deodorization of the water
closet space 411 which is a space wider than the inside of the toilet bowl 421.
[0377] Subsequently, control of performing the method of sterilizing and deodorizing the
water closet space 411 will be described.
[0378] In the present embodiment D1, a control unit (not shown) is configured to be capable
of controlling sterilization and deodorization of the water closet space 411 in one
control mode selected among three control modes, that is, first to third control modes.
[0379] In the first control mode, when it is recognized by a signal from a timer that it
has become a drive starting time set in advance, control of driving sterilization
and deodorization of the water closet space 411 starts. When it is recognized that
by a signal from the timer that a predetermined time period set in advance has elapsed,
control of driving sterilization and deodorization of the water closet space 411 stops.
For example, the drive starting time is set to a time zone in which frequency of use
of the toilet stool 41 is low, such as at night.
[0380] In the first control mode, when any of the first sensor and the second sensor has
detected a user at the drive starting time, control of driving sterilization and deodorization
of the water closet space 411 does not start. At a time point of a state where both
the first sensor and the second sensor have detected no user, control of driving sterilization
and deodorization of the water closet space 411 starts. In addition, in the first
control mode, at the drive starting time, when a closed state of the toilet lid 45
is detected by the third sensor, the toilet lid 45 is automatically in an opened state
so that the toilet lid 45 is in a state of being opened, and then control of driving
sterilization and deodorization of the water closet space 411 starts.
[0381] In the first control mode, during control of driving sterilization and deodorization
of the water closet space 411, when any of the first sensor and the second sensor
has detected a user, driving of sterilization and deodorization of the water closet
space 411 stops. In addition, in the first control mode, during control of driving
sterilization and deodorization of the water closet space 411, when a closed state
of the toilet lid 45 is detected by the third sensor, driving of sterilization and
deodorization of the water closet space 411 stops.
[0382] In the second control mode, control of driving sterilization and deodorization of
the water closet space 411 is performed in a state where the toilet lid 45 is closed.
In the second control mode, control similar to that in the first control mode is performed
except for the opened/closed state of the toilet lid 45.
[0383] Therefore, in the second control mode, at the drive starting time, when a closed
state of the toilet lid 45 cannot be detected by the third sensor, the toilet lid
45 is automatically in a closed state, and then control of driving sterilization and
deodorization of the water closet space 411 starts.
[0384] In the second control mode, during control of driving sterilization and deodorization
of the water closet space 411, in a case of a state where the toilet lid 45 is in
an opened state and a closed state of the toilet lid 45 cannot be detected by the
third sensor, control of driving sterilization and deodorization of the water closet
space 411 may stop or does not have to stop. In addition, in the second control mode,
the shutter 492 may be set to be in a downwardly open state.
[0385] In the third control mode, a user arbitrarily starts and stops control of driving
sterilization and deodorization of the water closet space 411. For example, a switch
(not shown) for starting and stopping control of driving sterilization and deodorization
of the water closet space 411 is provided in the toilet stool 41 or the water closet
space 411. When a user operates this switch, control of driving sterilization and
deodorization of the water closet space 411 starts or stops.
[0386] In the present embodiment D1, control over sterilizing and deodorizing the inside
of the toilet bowl 421 for sterilizing and deodorizing the inside of the toilet bowl
421 and control of stopping sterilizing and deodorizing the inside of the toilet bowl
421 are performed similar to control over sterilizing and deodorizing the water closet
space 411 and control of stopping sterilizing and deodorizing the inside of the toilet
bowl 421 in a time period not overlapping the time period in which control over sterilizing
and deodorizing the water closet space 411 is performed.
[0387] Next, operations and effects of the toilet stool according to the present embodiment
D1 described above will be described by using the drawings.
[0388] The toilet stool 41 according to the present embodiment D1 described above is capable
of suctioning air in the toilet bowl 421 to the duct 471 of the sterilizing/deodorizing
device 47 through the suction port 491d and is capable of causing air which has been
discharged through the discharge port 491e for performing sterilization and deodorization
to be directed toward the inside of the toilet bowl 421. Accordingly, the inside of
the toilet bowl 421 can be sterilized and deodorized. In addition, the toilet stool
41 is capable of suctioning air of the water closet space 411 above the toilet bowl
421 to the duct 471 of the sterilizing/deodorizing device 47 through the suction port
491d and is capable of causing air which has been discharged through the discharge
port 491e of the sterilizing/deodorizing device 47 for performing sterilization and
deodorization to be directed upward from the toilet bowl 421. Accordingly, the water
closet space 411 can be sterilized and deodorized.
[0389] Accordingly, sterilization and deodorization of the inside of the toilet bowl 421,
and sterilization and deodorization of the water closet space can be performed by
using the same sterilizing/deodorizing device 47.
[0390] In addition, in the toilet stool 41 according to the present embodiment D1, the shutter
492 capable of opening and closing the suction port 491d and the discharge port 491e
of the sterilizing/deodorizing device 47 is provided. When the shutter 492 is in an
upwardly open state, air above the toilet bowl 421 is guided so as to be introduced
to the suction port 491d, and air discharged through the discharge port 491e is guided
so as to be directed upward from the toilet bowl 421. Accordingly, even though a mechanism
for causing the suction port 491d and the discharge port 491e to be directed upward
is not provide in the sterilizing/deodorizing device 47, or even though a dedicated
component for introducing air above the toilet main body 42 to the suction port 491d
or a dedicated component for causing air discharged through the discharge port 491e

and deodorized.
[0391] In addition, in the toilet stool 41 according to the present embodiment D1, in a
state where the toilet lid 45 is closed, air discharged through the discharge port
491e flows out through the gap 4d2 between the toilet lid 45 and the upper surface
42a of the toilet main body 42. Accordingly, air for performing sterilization and
deodorization can be released to the water closet space 411 through the gap 4d2 between
the toilet lid 45 and the upper surface 42a of the toilet main body 2. As a result,
the side surface of the toilet stool 41 or a floor on which the toilet stool 41 is
installed can be sterilized and deodorized.
[0392] In addition, in the toilet stool 41 according to the present embodiment D1, in a
state where the toilet lid 45 is opened, air discharged through the discharge port
491e is directed upward from the toilet bowl 421. Accordingly, air for performing

in a wider range, without coming into contact with the toilet lid 45.
[0393] In addition, in the toilet stool 41 according to the present embodiment D1, a seating
sensor which detects that a user sits on the toilet seat 44 is provided. When the
seating sensor detects that a user sits on the toilet seat 44, the sterilizing/deodorizing
device 47 stops being driven. Accordingly, it is possible to prevent a user sitting
on the toilet seat 44 from being in contact with air for performing sterilization
and deodorization.
[0394] In addition, in the toilet stool 41 according to the present embodiment D1, the illumination
device 48 which illuminates the inside of the toilet bowl 421 is provided. In a time
period during which the sterilizing/deodorizing device 47 is driven, the illumination
device 48 illuminates the inside of the toilet bowl 421. Accordingly, a user can check
for whether or not the sterilizing/deodorizing device 47 is driven, by visually recognizing
whether or not the inside of the toilet bowl 421 is illuminated.
[0395] In addition, the sterilizing/deodorizing device 47 has an ion generating device for
releasing ions and discharges air including ions generated by the ion generating device,
through the discharge port 491e. Accordingly, the water closet space 411 can be efficiently
sterilized by utilizing ions.
[0396] Hereinabove, the embodiment D1 for the toilet stool according to the present invention
has been described. However, the present invention is not limited to the embodiment
D1 and can be suitably changed within a range not departing from the gist thereof.
[0397] For example, in the embodiment D1, the sterilizing/deodorizing device 47 which performs

591a, the second forward/rearward nozzle movement port 591b, the discharge port 591c
of the warm air drying unit 563, and the suction port 591d and the discharge port
591e of the sterilizing/deodorizing device 57 are formed will be referred to as an
opening forming portion 591.
[0418] A shutter 592 for the opening forming portion 591 switching between a covered state
(refer to FIG. 36) and an exposed state (refer to FIGS. 37 and 38) is provided on
the front surface 59a of the case 59. The shutter 592 is configured to be capable
of opening and closing the opening forming portion 591 in accordance with any one
of the first nozzle 5611 and the second nozzle 5612 moving forward and rearward.
[0419] The shutter 592 extends in the width direction and is formed to have a plate shape
having a size to the extent that the opening forming portion 591 of the case 59 can
be blocked. The shutter 592 is supported by a pair of support tools 593 and 593 provided
on the front surface 59a of the case 59. The pair of support tools 593 and 593 is
attached to a surface (surface on a side facing the opening forming portion 591 of
the case 59) 592a on the inner side of the shutter 592 at an interval in the width
direction. In the present embodiment E1, the shutter 592 is attached so as to be attachable
and detachable with respect to the pair of support tools 593 and 593. The pair of
support tools 593 and 593 supports the shutter 592 so as to be pivotable about the
pivot axis 594 extending in the width direction in an intermediate portion of the
shutter 592 in the height direction.
[0420] Two projection portions 595 and 596 are formed on the surface 592a on the inner side
of the shutter 592. One of the two projection portions 595 and 596 serves as a first
protrusion portion 595 and the other serves as a second protrusion portion 596. The
first protrusion portion 595 is formed at a position of facing the tip end portion
of the first nozzle 5611 in a state where the shutter 592 covers the opening forming
portion 591. In the first protrusion portion 595, the tip end portion is arranged
above a pivot axis 594. In addition, the second protrusion portion 596 is formed at
a position of facing the tip end portion of the second nozzle 5612 in a state where
the shutter 592 covers the opening forming portion 591. In the second protrusion portion
596, the tip end portion is arranged on a side lower than the pivot axis 594.
[0421] In a state where the shutter 592 covers the opening forming portion 591, when the
first nozzle 5611 moves to the front side in the moving direction of the nozzle, the
tip end portion of the first nozzle 5611 presses the shutter 592 to the front side
in a state of abutting on the tip end portion of the first protrusion portion 595
on a side upper than the pivot axis 594. Accordingly, as shown in FIG. 37, the shutter
592 is in an opened state (upwardly open state) in which the shutter 592 pivots about
the pivot axis 594 and the upper side is open such that the surface 592a on the inner
side is directed to the upper side and a surface 592b on the outer side is directed
to the lower side.
[0422] On the other hand, in a state where the shutter 592 covers the opening forming portion
591, when the second nozzle 5612 moves to the front side in the moving direction of
the nozzle, the tip end portion of the second nozzle 5612 presses the shutter 592
to the front side in a state of abutting on the tip end portion of the second protrusion
portion 596 on a side lower than the pivot axis 594. Accordingly, as shown in FIG.
38, the shutter 592 is in an opened state (downwardly lying open state) in which the
shutter 592 pivots about the pivot axis 594 and the lower side is open such that the
surface 592a on the inner side is directed to the lower side and the surface 592b
on the outer side is directed to the upper side.
[0423] The first nozzle 5611 and the second nozzle 5612 have a function of washing a private
part and also play a role as an operation member which maintains the shutter 592 in
an upwardly open state or a downwardly open state.
[0424] In a case where washing is performed by the first nozzle 5611, the second nozzle
5612 moves to the front side in the moving direction of the nozzle such that the shutter
592 is in a downwardly open state, and then the first nozzle 5611 moves to the front
side. At this time, the tip end part of the first nozzle 5611 moves forward beyond
the shutter 592 from the lower side of the shutter 592. When the shutter 592 is in
a downwardly open state and the tip end part of the first nozzle 5611 is in a state
of being arranged on the front side of the shutter 592, washing is performed by the
first nozzle 5611.
[0425] In a case where washing is performed by the second nozzle 5612, the second nozzle
5612 moves to the front side in the moving direction of the nozzle such that the shutter
592 is in a downwardly open state. Furthermore, the second nozzle 5612 moves forward
in the moving direction of the nozzle. When the shutter 592 is in a downwardly open
state and the tip end part of the second nozzle 5612 is in a state of being arranged
on the front side of the shutter 592, washing is performed by the second nozzle 5612.
[0426] In this manner, washing is performed when the shutter 592 is in a downwardly open
state and the surface 592a on the inner side of the shutter 592 is in a state of being
directed downward. Therefore, there is a low possibility that a spray generated at
the time of washing adheres to the surface 592a on the inner side of the shutter 592.
As a result, when the shutter 592 is closed after washing, it is possible to prevent
or suppress a spray from entering the inside of the case 59.
[0427] As shown in FIG. 37, the sterilizing/deodorizing device 57 is arranged so as to surround
the nozzle unit 561 of the private part washing device 56 in a substantial middle
portion of the functional section 53 in the width direction. As shown in FIG. 39,
the sterilizing/deodorizing device 57 has a duct 571, a sterilizing/deodorizing fan
572, a deodorizing cartridge 573, a sterilizing unit 574, and the dust collection
filter 575. The duct 571 is arranged so as to surround the nozzle unit 561 (refer
to FIG. 37). The fan 572 is provided in the middle of the duct 571. The deodorizing
cartridge 573 is arranged on the upstream side of the fan 572. The sterilizing unit
574 is provided on the downstream side of the fan 572. The dust collection filter
575 is provided on the upstream side (suction port 591d side) of the deodorizing cartridge
573.
[0428] The duct 571 is configured to suck air in the toilet bowl 521 (refer to FIG. 36)
through the suction port 591d formed on the front surface 59a of the opening forming
portion 591 of the case 59 and to discharge air, which has passed through the duct
571, through the discharge port 591e. In the present embodiment E1, the suction port
591d and the discharge port 591e are arranged on the upper portion side of the toilet
main body 52 and are open obliquely downward to the inside of the toilet bowl 521.
Therefore, the duct 571 is configured to suction air in the toilet bowl 521 and discharge
air, which has passed through the duct 571, to the inside of the toilet bowl 521.
[0429] In addition, a dust collection filter attachment portion 5711 for attaching the dust
collection filter 575 is provided in the duct 571.
[0430] The dust collection filter attachment portion 5711 communicates with the inside of
the toilet bowl 521 via the dust collection filter attaching and detaching port 591f.
The dust collection filter 575 is attached and detached with respect to the dust collection
filter attachment portion 5711 via the dust collection filter attaching and detaching
port 591f from the inside of the toilet bowl 521. The dust collection filter attachment
portion 5711 will be described below.
[0431] The deodorizing cartridge 573 is internally equipped with a deodorizing catalyst

cartridge 573, for example, an adsorption-type deodorant which employs activated carbon
or the like as a catalyst, or a decomposition-type deodorant such as a photocatalyst
which decomposes a substance by emitting a ray of light such as an ultraviolet is
used.
[0432] The sterilizing unit 574 has a function of generating sterilizing ions, suppressing
propagation of floating fungi, and performing sterilization. Specifically, the sterilizing
unit 574 ionizes air, generates positive ions and negative ions, surrounds floating
fungi by means of the positive ions and the negative ions, and inactivates the floating
fungi.
[0433] As shown in FIGS. 40A and 40B, the dust collection filter 575 is formed to have a
plate shape. The dust collection filter 575 has a dust collecting portion 5751, a

the first lower plate portion 5712. The first rear plate portion 5714 is formed throughout
the substantially entire duct 571 in the height direction. The first rear plate portion
5714 is arranged on the suction port 591d side of the dust collection filter attachment
portion 5711. The first rear plate portion 5714 is formed to have a shape of overlapping
a part in the vicinity of the rear edge portion of the dust collecting portion 5751
of the dust collection filter 575 attached to the dust collection filter attachment
portion 5711, in the width direction.
[0445] The lower end portion of the second rear plate portion 5715 continuously leads to
the second lower plate portion 5713. The second rear plate portion 5715 is formed
on a side lower than an intermediate portion of the duct 571 in the height direction.
The second rear plate portion 5715 is arranged on the deodorizing cartridge 573 side
of the dust collection filter attachment portion 5711. The second rear plate portion
5715 is formed to have a shape of overlapping a part in the vicinity of the rear edge
portion of the dust collecting portion 5751 of the dust collection filter 575 attached
to the dust collection filter attachment portion 5711, in the width direction.
[0446] As shown in FIG. 42, the dust collection filter 575 is attached to the dust collection
filter attachment portion 5711 in a direction in which the surface 5751b having the
protruding portion 5754 formed thereon faces the second lower plate portion 5713 and
the second rear plate portion 5715. In the dust collection filter 575 attached to
the dust collection filter attachment portion 5711, the rear end portion 575a abuts
on or approaches the rear surface 571b of the duct 571, and the protruding portion
5754 formed in the dust collecting portion 5751 is configured to be arranged in the
upper portion of the second rear plate portion 5715.
[0447] At this time, as shown in FIG. 43, when the dust collection filter 575 is intended
to be attached to the dust collection filter attachment portion 5711 in a direction
in which the surface having the protruding portion 5754 formed thereon faces the first
lower plate portion 5712 and the first rear plate portion 5714, the protruding portion
5754 of the dust collection filter 575 comes into contact with the front end portion
of the first rear plate portion 5714. Accordingly, a rear end portion 575a of the
dust collection filter 575 is separated from the rear surface 571b of the duct 571.
As a result, the dust collection filter 575 is set so as not to be capable of being
attached to the dust collection filter attachment portion 5711.
[0448] As shown in FIG. 42, in the dust collection filter attachment portion 5711, an upper
engagement portion 5759 having a concave portion shape recessed on the upper side
is formed on an upper surface 571c of the duct 571, and a lower engagement portion
5760 having a concave portion shape recessed on the lower side is formed on the lower
surface 571a of the duct 571.
[0449] The upper engagement portion 5759 is arranged at a position facing the upper engagement
target portion 5755 of the dust collection filter 575 attached to the dust collection
filter attachment portion 5711. The lower engagement portion 5760 is arranged at a
position facing the lower engagement target portion 5756 of the dust collection filter
575 attached to the dust collection filter attachment portion 5711.
[0450] When the dust collection filter 575 is attached to the dust collection filter attachment
portion 5711, the upper engagement target portion 5755 enters the upper engagement
portion 5759 and is engaged, and the lower engagement target portion 5756 enters the
lower engagement portion 5760 and is engaged.
[0451] In addition, when the dust collection filter 575 is attached to the dust collection
filter attachment portion 5711, the handgrip 5752 is arranged so as to protrude to
the inside of the toilet bowl 521 (refer to FIG. 36) beyond the dust collection filter
attaching and detaching port 591f (opening forming portion 591 of the case 59). The
handgrip 5752 is formed to have a shape which is accommodated in a gap 597 between
the surface 592a on the inner side of the shutter 592 and the opening forming portion
591 of the case 59, in a state where the shutter 592 is closed. In the present embodiment
E1, the surface 592a on the inner side of the shutter 592 in a closed state is formed
into a curved surface on which the intermediate portion in the height direction is
recessed toward the inside of the toilet bowl 521 from the upper end portion and the
lower end portion. When the shutter 592 is in a closed state, the R-shaped front end
portion of the handgrip 5752 is arranged on the inner side of the curved surface of
the surface 592a on the inner side of the shutter 592.
[0452] When the dust collection filter 575 is attached to the dust collection filter attachment
portion 5711, the shutter 592 is first in an upwardly open state and the dust collection
filter attaching and detaching port 591f is exposed. Subsequently, the handgrip 5752
of the dust collection filter 575 is gripped, and the dust collection filter 575 is
inserted into the dust collection filter attachment portion 5711 via the dust collection
filter attaching and detaching port 591f.
[0453] At this time, in the dust collection filter 575, the upper engagement target portion
5755 of the interlink portion 5753 comes into contact with the dust collection filter
attaching and detaching port 591f and the upper surface 571c of the duct 571, and
the upper end portion side of the interlink portion 5753 is elastically deformed such
that the upper opening portion 5757 is squashed. In addition, in the dust collection
filter 575, the lower engagement target portion 5756 of the interlink portion 5753
comes into contact with the dust collection filter attaching and detaching port 591f
and the lower surface 571a of the duct 571, and the lower end portion side of the
interlink portion 5753 is elastically deformed such that the lower opening portion
5758 is squashed.
[0454] When the protruding portion 5754 of the dust collection filter 575 is arranged on
the second rear plate portion 5715 and the dust collection filter 575 is inserted
to the correct position, the upper engagement target portion 5755 enters the upper
engagement portion 5759 and is engaged with the dust collection filter attachment
portion 5711, and the lower engagement target portion 5756 enters the lower engagement
portion 5760 and is engaged with the dust collection filter attachment portion 5711.
[0455] When the dust collection filter 575 is removed from the dust collection filter attachment
portion 5711, the shutter 592 is first in an upwardly open state and the dust collection
filter attaching and detaching port 591f is exposed. Subsequently, the handgrip 5752
of the dust collection filter 575 is gripped, and the dust collection filter 575 is
pulled and removed from the dust collection filter attachment portion 5711 via the
dust collection filter attaching and detaching port 591f.
[0456] In this manner, the sterilizing/deodorizing device 57 is configured to collect dust
by using the dust collection filter 575 from air sucked to the duct 571 through the
suction port 591d and performs deodorization by causing the air to pass through the
deodorizing cartridge 573. Furthermore, the air is caused to be air including positive
ions and negative ions by the sterilizing unit 574 and is discharged through the discharge
port 591e.
[0457] Next, operations and effects of the deodorizing device and the toilet stool described
above will be described by using the drawings.
[0458] In the present embodiment E1 described above, the dust collection filter attaching
and detaching port 591f can be opened and closed by the shutter 592. Accordingly,
when a user uses the toilet stool 51, the shutter 592 is in a closed state, so that
it is possible to prevent a spray from entering the dust collection filter attachment
portion 5711 via the dust collection filter attaching and detaching port 591f. As
a result, it is possible to prevent the dust collection filter 575 from being unclean
due to a spray.
[0459] In addition, the handgrip 5752 is provided in the dust collection filter 575. Accordingly,
when the shutter 592 is open and the handgrip 5752 of the dust collection filter 575
is gripped, a user can easily attach and detach the dust collection filter 575 with
respect to the dust collection filter attachment portion 5711.
[0460] In addition, when the dust collection filter 575 is attached to the dust collection
filter attachment portion 5711, the upper engagement target portion 5755 enters the
upper engagement portion 5759 and is engaged, and the lower engagement target portion
5756 enters the lower engagement portion 5760 and is engaged. Accordingly, the dust
collection filter 575 can be installed in the dust collection filter attachment portion
5711. In addition, it is possible to prevent position aberration of the dust collection
filter 575 in the dust collection filter attachment portion 5711.
[0461] In addition, the dust collection filter 575 has a set attachment direction with respect
to the dust collection filter attachment portion 5711 and has a configuration in which
the protruding portion 5754 of the dust collection filter 575 is arranged on the second
rear plate portion 5715. Accordingly, the dust collection filter 575 can be attached
to the dust collection filter attachment portion 5711 in the correct direction.
[0462] In addition, when the dust collection filter 575 is attached and detached with respect
to the dust collection filter attachment portion 5711 after the shutter 592 is in
an upwardly open state, the dust collection filter 575 can be attached and detached
with respect to the dust collection filter attachment portion 5711 from the upper
side of the shutter 592. Therefore, the dust collection filter 575 can be easily attached
and detached with respect to the dust collection filter attachment portion 5711.
[0463] In addition, when the shutter 592 is in an upwardly open state, the surface 592b
on the outer side of the shutter 592 which often becomes unclean due to a spray becomes
a lower side, thereby being less likely to be touched by a user. Therefore, it is
possible to prevent a user from touching a spray on the surface 592b on the outer
side of the shutter 592.
[0464] Hereinabove, the embodiment E1 for the deodorizing device and the toilet stool according
to the present invention has been described. However, the present invention is not
limited to the embodiment E1 and can be suitably changed within a range not departing
from the gist thereof.
[0465] For example, in the embodiment E1, the handgrip 5752 is provided in the dust collection
filter 575. However, the handgrip 5752 does not have to be provided as long as a user
can attach and detach the dust collection filter 575 with respect to the dust collection
filter attachment portion 5711.
[0466] In addition, in the configuration of the embodiment E1, the upper engagement target
portion 5755 and the lower engagement target portion 5756 are formed in the dust collection
filter 575, the upper engagement portion 5759 and the lower engagement portion 5760

other hand, the reverse attachment prevention mechanism for the dust collection filter
575 does not have to be provided.
[0469] In addition, a reverse attachment prevention mechanism for the dust collection filter
575 in a different form may be provided. For example, a fitting portion may be formed
in the duct 571 such that the dust collection filter 575 is fitted in a case of the
correct direction and the dust collection filter 575 is not fitted in a case of the
reverse direction.
[0470] In addition, in the embodiment E1, the shutter 592 has a form of being in both the
open states, that is, an upwardly open state and a downwardly open state. On the other
hand, the shutter 592 may have a form of being in only a downwardly open state. In
this case, the shutter 592 is in a downwardly open state and the dust collection filter
575 is attached and detached with respect to the dust collection filter attachment
portion 5711. In addition, the mechanism of opening and closing the shutter 592 may
be a form other than those described above.
[0471] In addition, in the embodiment E1, the shutter 592 is maintained in an upwardly open
state or a downwardly open state by any one of the first nozzle 5611 and the second
