TECHNICAL FIELD
[0001] This disclosure generally relates to a private part washing nozzle according to the
preamble of claim 1 used for a human body private part washing apparatus.
BACKGROUND DISCUSSION
[0002] A known private part washing nozzle described in
JP 2007 239245 A (which will be hereinafter referred to as Patent reference 1) includes a nozzle head
which is attachable to and removable from a nozzle main body. The nozzle head is attached
to and removable from the nozzle main body by rotating the nozzle head. A generic
private part washing nozzle according to the preamble of claim 1 is shown in
US 2011/203044 A1.
[0003] A need thus exists for a private part washing nozzle which is downsized and includes
a nozzle head that is attachable and removable by rotation.
SUMMARY
[0004] This objective is achieved by a private part washing nozzle having the features of
claim 1. Further advantageous developments of the present invention are set out in
the dependent claims.
[0005] According to the present invention, a private part washing nozzle includes a nozzle
head including a plurality of types of spray ports each spraying washing water, a
head support body including a plurality of flow passages delivering the washing water
to the respective plurality of types of spray ports, the head support body including
a connection portion provided at a distal end side of the head support body, the connection
portion being connected to the nozzle head, and the connection portion being provided
at a position in such a manner that the connection portion is eccentric relative to
a central axis of the nozzle head.
[0006] According to the above-described configuration, the connection portion is provided
at the position in such a manner that the connection portion is eccentric relative
to the central axis of the nozzle head, and thus elements necessary to the private
part washing nozzle can be arranged at a first side relative to a central axis of
the connection portion. That is, a portion at a second side relative to the central
axis of the connection portion can be made smaller, and accordingly the nozzle can
be downsized.
[0007] Preferably, the connection portion is a single connection portion.
[0008] According to the above-described configuration, the nozzle head can be attached to
and removed from the head support body by rotating the nozzle head relative to the
head support body.
[0009] Preferably, one of the plurality of flow passages provided at the head support body
and delivering the washing water to the respective plurality of types of spray ports
includes a linear configuration of which a central axis is coaxial to a central axis
of the connection portion.
[0010] According to the above-described configuration, from among the plural flow passages
formed at the head support body, any one of the flow passage includes the linear configuration
of which the central axis is coaxial to the central axis of the connection portion.
Accordingly, pressure loss is restricted from occurring at the flow passage. In addition,
it can be restricted that an area or region which is occupied by the flow passage
and the connection portion increases in the width direction, thereby leading to the
reduction in size of the nozzle.
[0011] Preferably, the flow passage formed in the linear configuration including the central
axis that is coaxial to the eccentric axis of the connection portion corresponds to
the flow passage delivering the washing water to the spray port at which pressure
of the washing water sprayed therefrom is the highest.
[0012] According to the above-described configuration, the pressure loss is restricted from
occurring at the flow passage that requires washing pressure the most.
[0013] According to the present invention, the connection portion includes a multilayer
pipe structure in which a plurality of pipe portions are arranged to overlap with
each other in a radial direction, and a space portion formed inside the pipe portion
arranged most inwardly in the radial direction corresponds to a part of the flow passage
delivering the washing water to one of the plurality of types of spray ports, and
a space portion formed between the plurality of pipe portions corresponds to a part
of the flow passage delivering the washing water to another of the plurality of types
of spray ports.
[0014] According to the above-described configuration, the connection portion includes the
multilayer pipe structure, and accordingly the space portion inside the pipe portion
which is arranged most inwardly in the radial direction forms part of the flow passage
delivering the washing water to one of the plurality of types of spray ports, and
the space portion formed between the plural pipe portions forms part of the flow passage
delivering the washing water to another of the plural types of spray ports. That is,
the plural flow passages are established by the one connection portion.

DETAILED DESCRIPTION
[0016] A private part washing nozzle 1 according to an embodiment of this disclosure will
be explained with reference to the drawings. In the explanation, a front and rear
direction is a direction (an X direction illustrated in the drawings) along a long-side
direction of the private part washing nozzle 1, and a side of a user using the private
part washing nozzle 1 corresponds to a front side. An upper and lower direction is
a direction (a Z direction illustrated in the drawings) that is orthogonal to the
front and rear direction, and a side at which washing water is sprayed or discharged
corresponds to an upper side. A width direction is a direction (a Y direction illustrated
in the drawings) that is orthogonal to the front and rear direction and the upper
and lower direction.
[0017] The private part washing nozzle 1 according to the present embodiment is applied
to a human body private part washing apparatus 90. As illustrated in Fig. 1, the human
body private part washing apparatus 90 is arranged inside an accommodation space portion
92 provided at a rear portion of a toilet seat 91, for example. The private part washing
nozzle 1 moves back and forth, that is, moves to advance and retract, in a substantially
front and rear direction. A structure for causing the private part washing nozzle
1 to advance and retract may be any structure. A structure may be used in which the
private part washing nozzle 1 is moved to advance and retract by an electrical drive
source including a motor. A structure may be used in which the private part washing
nozzle 1 is caused to advance with the use of water pressure of water for washing
and is caused to retract by a biasing member including a spring. A structure of the
human body private part washing apparatus 90 other than the private part washing nozzle
1, for example, the structure of the drive mechanism of the nozzle, may be any kind
and form (a similar structure to a publicly known structure may be used). Therefore,
explanation thereof is omitted.
[0018] The private part washing nozzle 1 illustrated in Figs. 2 to 4C according to the present
embodiment includes a nozzle head 10 (i.e., a nozzle head) and a head support body
20 (i.e., a head support body). The nozzle head 10 forms a distal end portion of the
private part washing nozzle 1, and an spray port from which washing water is sprayed
is provided at the nozzle head 10. The nozzle head 10 of the present embodiment is
provided with plural types of spray ports. The plural types of spray ports are provided
to correspond to respective modes of washing in a case where the private part washing
nozzle 1 is applied to the human body private part washing apparatus 90. A hole constituting
each of the plural types of spray ports does not need to be one. Plural holes may
form one type of spray port.
[0019] The nozzle head 10 of the present embodiment is provided with two types of spray
ports (that is, a first spray port 11 and a second spray port 12) (refer to Figs.
2 and 4A to 4C). The first spray port 11 and the second spray port 12 serve as spray
ports of this disclosure. The first spray port 11 is for performing washing with a
relatively high washing pressure (a powerful washing) and the second spray port 12
is for performing washing with a relatively low washing pressure (a mild washing).
That is, a flow speed of the washing water sprayed from the first spray port 11 is
larger than a flow speed of the washing water sprayed from the second spray port 12.
For example, in a case where water pressures for delivering or transmitting the washing
water to the respective spray ports are substantially same as each other, the pressure
of the washing water sprayed from the first spray port 11 becomes higher than the
pressure of the washing water sprayed from the second spray port 12 by setting a size
(a cross-sectional area) of the smallest portion in the first spray port 11 to be
smaller than a size (a cross-sectional area) of the smallest portion in the second
spray port 12. In a case where the spray port is constituted by plural holes, the
size of the spray port corresponds to total of sizes (cross-sectional areas) of the
smallest portions of the respective plural holes.
[0020] As illustrated in the cross-sectional views of Figs. 3A to 4C, a first space portion
13 connected to the first spray port 11 and a second space portion 14 connected to
the second spray port 12 are formed inside the nozzle head 10. The first space portion
13 is positioned at a front side (a distal end side) relative to the second space
portion 14. The first space portion 13 and the second space portion 14 are defined
by a connection portion 21 (i.e., a connection portion) of the head support body 20.
A fitting portion 15 including a cylindrical configuration is formed at a center of
a wall defining or separating the first space portion 13 and the second space portion
14. The connection portion 21 engages with the fitting portion 15 (the connection
portion 21 will be described below in detail). The washing water that has flowed into
the first space portion 13 is sprayed or spouts from the first spray port 11 and the
washing water that has flowed into the second space portion 14 is sprayed or spouts
from the second spray port 12.
[0021] The head support body 20 is connected to a rear side of the nozzle head 10. The head
support body 20 constitutes flow passages through which the washing water flows and
is delivered to the nozzle head 10. The head support body 20 includes the connection
portion 21 projecting towards the distal end side. The connection portion 21 includes
an external appearance of an axial shape having a circular cross section. The nozzle
head 10 is connected to the connection portion 21. The head support body 20 of the
present embodiment is provided with the one connection portion 21, that is, the single
connection portion 21. A specific configuration of the connection portion 21 will
be described hereunder.
[0022] The connection portion 21 of the present embodiment includes a multilayer pipe structure
in which plural pipe portions are arranged to overlap with each other in a radial
direction. The number of the plural pipe portions is identical to the number of types
of the spray ports. That is, the connection portion 21 of the present embodiment includes
a double layer pipe structure formed of the two pipe portions, that is, a first pipe
portion 211 and a second pipe portion 212. The first pipe portion 211 and the second
pipe portion 212 serve as pipe portions of this disclosure. The first pipe portion
211 includes a portion projecting towards a distal end side relative to a distal end
side opening of the second pipe portion 212. In a state where the nozzle head 10 and
the head support body 20 are connected to each other, the first pipe portion 211 has
entered inside the fitting portion 15 of the nozzle head 10. Due to the above-described
configuration, a wall of the first pipe portion 211 serves as a partition wall defining
or separating between the second space portion 14. A space portion provided inside
the first pipe portion 211 forms a part of a flow passage delivering the washing water
to the first space portion 13 of the nozzle head 10 (refer to Figs. 3B and 4B).
[0023] On the other hand, in a state where the nozzle head 10 and the head support body
20 are connected to each other, a space portion between an outer surface of the first
pipe portion 211 and an inner surface of the second pipe portion 212 is connected
to the second space portion 14 of the nozzle head 10. That is, the space portion between
the first pipe portion 211 and the second pipe portion 212 forms a part of a flow
passage delivering the washing water to the second space portion 14 of the nozzle
head 10 (refer to Figs. 3B and 4B). Because the first pipe portion 211 is in a state
of having entered inside the fitting portion 15 of the nozzle head 10 as described
above, the washing water is restricted, due to the above-described state, from flowing
from one of the first space portion 13 (the first pipe portion 211) and the second
space portion 14 (the second pipe portion 212) to the other. A seal member, including
an O-ring, may be interposed between the outer surface of the first pipe portion 211
and an inner surface of the fitting portion 15.
[0024] The connection portion 21 includes a configuration for maintaining the engagement
of the head support body 20 and the nozzle head 10 with each other. The configuration
can be any kind and form. In the configuration according to the present embodiment,
as the nozzle head 10 is rotated in one direction relative to the head support body
20, the nozzle head 10 comes off the head support body 20. As the nozzle head 10 is
rotated in the other direction relative to the head support body 20, the nozzle head
10 is engaged with the head support body 20. That is, the configuration is formed
in which the nozzle head 10 is attachable to and removable from the head support body
20 by rotating the nozzle head 10. Accordingly, the user can clean the nozzle head
10 easily by removing only the nozzle head 10 from the human body private part washing
apparatus 90. Such a configuration for attaching and removing the nozzle head 10 by
the rotation of the nozzle head 10 is publicly known as described in Patent reference
1, and a specific configuration may be in any type and form. Therefore, detailed explanation
thereof is omitted. A seal member, including an O-ring, may be interposed between
an outer surface of the second pipe portion 212 and a portion of the nozzle head 10
(an inner surface of the nozzle head 10) with which the second pipe portion 212 engage.
The above-described configuration for attaching and removing the nozzle head 10 by
the rotation is formed or established because the single connection portion, that
is, the connection portion 21, is provided at the head support body 20.
[0025] The head support body 20 is provided with a port portion 22. A water supply hose
delivering the washing water is connected to the port portion 22. The number of the
port portion 22 is identical to the number of types of the spray ports. In the present
embodiment, two of the port portions are provided, that is, a first port portion 221
and a second port portion 222. The first port portion 221 and the second port portion
222 are cylindrical portions extended towards the rear side. A first water supply
hose 81 is configured to be connected to the first port portion 221 (refer to Fig.
2). The first water supply hose 81 delivers the wash water that is to be sprayed from
the first spray port 11. That is, the first port portion 221 forms part of the flow
passage through which the washing water is delivered or sent to the first spray port
11 (the first space portion 13). A second water supply hose 82 is configured to be
connected to the second port portion 222 (refer to Fig. 2). The second water supply
hose 82 delivers the wash water that is to be sprayed from the second spray port 12.
That is, the second port portion 222 forms part of the flow passage through which
the washing water is delivered to the second spray port 12 (the second space portion
14). As illustrated in Fig. 5, for example, a cover 83 formed in a cylindrical shape,
and covering the head support body 20 and/or part of distal end sides of the hoses
may be provided to the human body private part washing apparatus 90 to which the private
part washing nozzle 1 of the present embodiment is applied.
[0026] The first pipe portion 211 and the first port portion 221 both of which form the
flow passage of the washing water that is to be sprayed from the first spray port
11 are set such that a central axis of the first pipe portion 211 and a central axis
of the first port portion 221 coincide with or identical to each other (refer to Fig.
3B, for example). That is, the flow passage including the space portion inside the
first port portion 221 and the space portion inside the first pipe proton 211 and
leading to the first space portion 13 (the first spray port 11) (which will be hereinafter
referred to also as a first flow passage 201) is linear or in a straight state (that
is, a central axis is straight).
[0027] On the other hand, the flow passage of the washing water that is to be sprayed from
the second spray port 12, that is, the flow passage leading to the second space portion
14 (which will be hereinafter referred to also as a second flow passage 202), includes
a space portion formed inside the second port portion 222 and the space portion formed
between the first pipe portion 211 and the second pipe portion 212. A central axis
of the second port portion 222 differs from the central axis of the first pipe portion
211 and of the second pipe portion 212. That is, in order to connect the space portion
inside the second port portion 222, and the space portion formed between the first
pipe portion 211 and the second pipe portion 212 to each other, an intermediate portion
of the flow passage needs to be bent or curved, that is, the flow passage needs to
be partly bent or curved. In the present embodiment, the space portion of the second
port portion 222, and the space portion between the first pipe portion 211 and the
second pipe portion 212 are connected to each other by a junction space portion 23
provided at the head support body 20 (refer to Fig. 3B). As described above, in the
present embodiment, one of the two flow passages for supplying the washing water,
that is, the first flow passage 201, is linear. On the other hand, the other of the
two flow passages for supplying the washing water, that is, the second flow passage
202, includes the bent and curved portion. A pressure loss occurring in the flow passage
during the delivery of the washing water is larger in the second flow passage 202
than in the first flow passage 201. The first flow passage 201 and the second flow
passage 202 serve as flow passages of this disclosure.
[0028] For example, a positional relationship of the respective portions of the private
part washing nozzle 1 including the above configuration will be described below. The
central axis of the connection portion 21 (the central axis of the first pipe portion
211 and the second pipe portion 212) is eccentric relative to a central axis L1 (i.e.,
a central axis) of the nozzle head 10 (the central axis of the connection portion
21 will be hereinafter referred to also as an eccentric axis L2). That is, the eccentric
axis L2 serving as the central axis of the connection portion 21 and the central axis
L1 of the nozzle head 10 do not coincide with each other (refer to Figs. 3B and 4A,
for example). More specifically, the central axis L1 of the nozzle head 10 is set
to be positioned at a plane bisecting the nozzle head 10 in the width direction (which
is a plane that is away from both end portions in the width direction by an equal
distance; the same applies hereinafter), and the central axis (the eccentric axis
L2) of the connection portion 21 is set to be positioned at a first side of the plane
in the width direction. As described above, the first flow passage 201 is formed to
be linear, and the part of the first flow passage 201 includes the first pipe portion
211 and the first port portion 221, and therefore the central axis of the first flow
passage 201 is in a state of being eccentric to the central axis L1 of the nozzle
head 10 (the state in which the central axis of the first flow passage 201 coincides
with the eccentric axis L2). In the present embodiment, the central axis L1 of the
nozzle head 10 and a central axis of the head support body 20 coincide with each other
or identical to each other. That is, the plane bisecting the nozzle head 10 in the
width direction and a plane bisecting the head support body 20 in the width direction
match with each other. Consequently, it can be said that the central axis of the connection
portion 21 (the eccentric axis L2) is eccentric from the central axis L1 of the head
support body 20.
[0029] On the other hand, in the present embodiment, a central axis of the second port portion
222 serving as part of second flow passage 202 is also positioned to be eccentric
to the central axis L1 of the nozzle head 10 and of the head support body 20 (refer
to Figs. 3B and 4A, for example). Specifically, the central axis of the connection
portion 21 (the first flow passage 201) is positioned at the first side, in the width
direction, of the plane bisecting the nozzle head 10 in the width direction. The central
axis of the second port portion 222 is positioned at a second side, in the width direction,
of the plane bisecting the nozzle head 10 in the width direction. That is, at the
port portion 22, it is set in such a manner that the central axis of the first flow
passage 201 and the central axis of the second flow passage 202 are positioned to
be apart from each other, and the central axis L1 of the nozzle head 10 and of the
head support body 20 is positioned between the central axis of the first flow passage
201 and the central axis of the second flow passage 202. Because the central axis
of the first flow passage 201 and the central axis of the second flow passage 202,
which are arranged to be separated from each other at the port portion 22, come to
be identical to each other at the connection portion 21 (the eccentric axis L2), and
therefore the second flow passage 202 includes a bent or curved configuration in an
intermediate portion of the second flow passage 202, accordingly.
[0030] Due to the above-described positional relationships between the portions, the following
advantages can be obtained. Hypothetically speaking, as schematically illustrated
in Fig. 6A, in a case where a central axis of a connection portion 21a is configured
to be coincide with the central axis of a nozzle head 10a and a head support body
20a, that is, to coincide with an axis L1a, a portion (indicated with M in Fig. 6A)
at one side (a side opposite to a second port portion 222a) in the width direction
relative to the coincided central axis L1a (a plane bisecting the nozzle head 10a
and/or the head support body 20a in the width direction) corresponds to a wasted portion.
In other words, any elements necessary to constitute the private part washing nozzle
are not formed or arranged in the portion M. However, a size (a width) of the nozzle
is increased accordingly because the portion M exists.
[0031] To the contrary, according to the private part washing nozzle 1 of the present embodiment,
it is configured in such a manner that the connection portion 21 is eccentric to the
central axis L1 of the nozzle head 10 and of the head support body 20, and accordingly
the above-described wasted portion is not generated. More specifically, on the premise
that the above-described configuration for attaching and removing the nozzle head
10 by the rotation is provided, that is, with the assumption that the nozzle head
10 is attachable to and removable from the head support body 20 by rotating the nozzle
head 10, the connection portion 21 that is provided at the head support body 20 and
is connected to the nozzle head 10 needs to be one. The single connection portion
21 serves as a rotational center at the attachment and removal of the nozzle head
10, and thus the connection portion 21 normally needs to be arranged coaxially with
the central axis L1 of the nozzle head 10 and of the head support body 20. However,
the private part washing nozzle 1 of the present embodiment includes the configuration
in which the connection portion 21 is intentionally eccentric to the central axis
L1 of the nozzle head 10 and of the head support body 20, and therefore the nozzle
is restricted from being increased in size.
[0032] In addition, by utilizing the eccentricity of the connection portion 21, the first
flow passage 201 including the linear configuration is provided at the first side
in the width direction in the present embodiment. That is, the first flow passage
201 serving as one of the flow passages is formed in the linear configuration along
the eccentric axis L2, instead of a configuration in which both the first flow passage
201 and the second flow passage 202 are formed in bent or curved configurations. Accordingly,
the nozzle is restricted from being increased in size and pressure loss at the first
flow passage 201 is restricted from occurring. More specifically, as schematically
illustrated in Fig. 6B as a hypothetical example, in a case where a central axis L1b
of a connection portion 21b is configured to be coincide with a central axis of a
nozzle head 10b and/or a head support body 20b, and a first port portion 221b and
a second port portion 222b are arranged to be away from the central axis L1b by an
equal distance to each other, both a first flow passage 201b and a second flow passage
202b need to be formed in bent or curved configurations to restrict the nozzle from
being increased in size. However, according to the private part washing nozzle 1 of
the present embodiment, one of the flow passages is formed in the linear or straight
configuration with the use of the configuration where the connection portion 21 is
eccentric. Consequently, in the present embodiment, the advantages are obtained that
not only the increased size of the nozzle is restricted but also the loss of the pressure
at the flow passage having the linear configuration is restricted.
[0033] Further, in the present embodiment, the first flow passage 201, through which the
washing water is delivered to the first spray port 11 at which the washing pressure
is relatively high, is formed in the linear configuration. That is, the pressure loss
is restricted at the first flow passage 201 through which the washing water to the
first spray port 11, where the washing pressure is higher, is delivered (in other
words, increment in the pressure loss is accepted or allowed at the second flow passage
202 through which the washing water is delivered to the second spray port 12, where
the washing pressure can be relatively low). Consequently, a washing performance is
enhanced in the present embodiment.
[0034] The embodiment disclosed here is explained above in detail, however, the present
disclosure is not limited to the above-described embodiment. Various modifications
and changes may be made without departing from the spirit and scope of this disclosure.
[0035] For example, in the above-described embodiment, the portion supporting the nozzle,
that is, the connection portion 21, is illustrated as a member that is relatively
short in the front and rear direction (a member that is shorter than the nozzle head
10), however, the embodiment is an example. For example, the size of the member may
be changed appropriately as long as the member includes a distal end at which the
nozzle head 10 is supported and the member is provided with the flow passages through
which the washing water is delivered or sent to the respective spray ports.
[0036] In addition, in the above-described embodiment, the two kinds of spray ports are
provided as the spray ports from which the washing water is sprayed, that is, the
first spray port 11 and the second spray port 12. However, the number of kinds or
types of the spray ports may be equal to or greater than three. In this case, the
multilayer pipe structure of the connection portion 21 may include the same number
of pipe portions as the number of the spray ports (for example, in a case where the
three types of the spray ports are formed, a three layer pipe structure may be applied),
and accordingly part of the flow passages delivering the washing water to the respective
spray ports is structured. In addition, in this case, any one of the plural flow passages
through which the washing water is delivered to the respective plural types of the
spray ports may be formed in the linear configuration. Further, the flow passage through
which the washing water is delivered to the spray port at which the pressure of the
washing water is the highest may ideally include the linear configuration.
[0037] A private part washing nozzle (1) includes a nozzle head (10) including a plurality
of types of spray ports (11, 12) each spraying washing water, a head support body
(20) including a plurality of flow passages (201, 202) delivering the washing water
to the respective plurality of types of spray ports, the head support body including
a connection portion (21) formed at a distal end side of the head support body, the
connection portion being connected to the nozzle head, and the connection portion
being provided at a position in such a manner that an eccentric axis (L2) of the connection
portion is eccentric relative to a central axis (L1) of the nozzle head.
1. A private part washing nozzle (1) comprising:
a nozzle head (10) including a plurality of types of spray ports (11, 12) each spraying
washing water; and
a head support body (20) including a plurality of flow passages (201, 202) delivering
the washing water to the respective plurality of types of spray ports (11, 12), the
head support body (20) including a connection portion (21) provided at a distal end
side of the head support body (20), the connection portion (21) being connected to
the nozzle head (10); wherein
a central axis (L1) of the nozzle head (10) and a central axis of the head support
body (20) coincide with each other; characterized in that
the connection portion (21) being provided at a position in such a manner that, in
a direction being orthogonal to both a direction in which the central axis (L1) of
