FIELD OF THE INVENTION
[0001] The disclosure generally relates to a bidet washing apparatus, and more particularly
to a bidet washing apparatus having a disinfectant wash feature that can store and
dispense a cleaning disinfectant with a bidet washing stream.
BACKGROUND OF THE INVENTION
[0002] A bidet apparatus for washing and cleaning body parts were initially developed in
the form of a bidet that provided a single spray of water and was permanently built
into the toilet bowl. However, such bidets were expensive, and a new generation of
bidets was developed that was attachable to the toilet and included a plurality of
nozzles for multiple water sprays. Such bidets can be attached to the seat of an existing
toilet bowl for washing the private parts of a person. Various bidet designs have
addressed some of the desired effects, such as washing, washing with temperature-regulated
water, and drying, However, existing bidets tail to address all concerns related to
the designs and functions in the general field of bidets. For example, pollution of
the outer surface of the nozzles, the bidet, and the toilet during utilization is
a common problem and causes aesthetic and hygienic issues. This is particularly important
in bidets used, for example, by infirm or sick people who have to be especially cautious
about maintaining hygiene and preventing infections.
[0003] Currently, there aren't any bidets that include a disinfectant wash feature. Many
bidets have a feature to clean the nozzle of the bidet, however, cleaning the nozzle
with water causes problems as it could leave behind hard water deposits and not provide
adequate cleaning. Hard water deposits on the nozzle could affect the flow of the
bidet as it blocks the nozzle holes and not adequately cleaning the bidet raises sanitary
concerns. Consumers may also feel that normal water may not provide adequate washing
of their body parts. Therefore, there remains a need to provide bidets with a disinfectant
wash feature.

[0032] The embodiments disclosed herein describe a new, clean and hygienic washing bidet.
The various embodiments include one or a plurality of water inlets, a control means
housing one or a plurality of control valves to control the flow of water from the
water inlets to one or a plurality of water tubes, one or a plurality of washing nozzles,
a protective shield gate, and securing unit configured to securing the sanitary washing
device to the toilet seat.
[0033] The disclosed embodiments directed to clean and hygienic bidet washing apparatus
100 attachable to an existing toilet, for cleaning the body parts of the user sitting
on or near the toilet.
[0034] As described herein, a "bidet" is a toilet attachment for cleaning the body parts
of the user. As described herein, the term "water inlet" means any structure that
may provide water to the bidet washing apparatus.
[0035] As described herein, a "control unit" (aka "control panel") is the housing which
has "control switch(s)" thereon controlling the various functionalities of the bidet,
including but, not limited to, the flow of water, adjusting the angle of the nozzles,
and opening and closing the protective shield gate.
[0036] As described herein, "control valves" are, controller parts located inside the control
panel housing which control the flow of water or other fluids from the water inlet(s)
to one or more "water tubes" by opening, closing, or partially obstructing various
passageways.
[0037] As described herein, "water tubes" are channels that connect the control valves to
a "nozzle assembly," wherein, the "nozzle assembly" includes a single nozzle or a
collection of nozzles including at least one "washing nozzle."
[0038] As described herein, a "nozzle" is a device designed to eject water or other fluids
into the surrounding medium as a coherently controlled spray.
[0039] As described herein, the "washing nozzle" is the nozzle that can be used to wash
the body parts of a user.
[0040] As described herein, the "nozzle assembly" may also have other types of nozzles such
as a "self-cleaning nozzle," which is used to clean the nozzle assembly itself, a
"toilet cleaning nozzle," which is used to clean the bidet and/or the toilet, and
a "shield cleaning nozzle," which is used for cleaning the "protective shield gate."
[0041] As described herein, the "protective shield gate" is a structure placed at least
partially in front of the nozzle assembly (e.g., between the user and the nozzle assembly)
to protect the nozzle assembly from pollutants.
[0042] As described herein, the "protective shield gate" ran has a "hinged" edge. The term
"hinged" here means a joint that allows the turning or pivoting of the gate, by any
conventional turning or pivoting mechanism.
[0043] As described herein, the term "fluidically coupled" means a connection or a passageway
that allows fluid to flow therethrough.
[0044] As described herein, the term "reservoir" means a fluid holding tank.
[0045] Accordingly, in one embodiment the disclosure provides a bidet washing apparatus
attachable to a toilet bowl for cleaning one or more body parts of a user. The apparatus
can include one or more water inlets configured to supply water, and a control unit,
housing one or more valves fluidically connected to the one or more water inlets,
including one or more control switches configured to operate the one or more valves.
As such, one or more valves can control water flow from one or more water inlets.
The apparatus can further include a nozzle assembly including at least one washing
nozzle, fluidically connected to at least one of the one or more valves with one or
more water tubes. At least one washing nozzle can be positioned for directing water
to one or more body parts of the user. The apparatus can also include a protective
shield gate covering at least a portion of at least one washing nozzle, where the
protective shield gate is rotatably coupled to the bidet washing apparatus.
[0046] According to various embodiments, the protective shield gate can be rotatably coupled
to the apparatus along a side or top edge via a hinge, for example, to allow for the
manual or electrical opening and closing of the protective shield gate. In this matter,
the nozzle(s) are easily accessible for cleaning, removal, replacement, or another
adjustment while the protective shield gate is open. In an alternative embodiment,
the protective shield gate can be completely removed to similarly provide access to
the nozzle(s).
[0047] According to another embodiment, the water inlet(s) can be fluidically connected
to one or more valves via a single-body connector without any intervening parts or
joints, which results in a more robust, long-lasting, bidet washing apparatus, since
leaks or other damage to the fluidic couplings are less likely to occur.
[0048] Referring to FIG. 1 and FIG. 2, the bidet washing apparatus 100 of the disclosure
can be mounted on a toilet bowl 110 using securing mechanisms 105a and 105b. Any conventional
securing unit can be implemented, e.g., one or more screws. A toilet seat 112 can
pivot around and can be connected to a rear portion of the toilet bowl 110. On the
rear portion of the toilet bowl, 110 can be mounted a refillable toilet tank 109,
in which an amount of water can be stored. In certain embodiments, toilet tank 109
can be used as the water source for the bidet washing apparatus 100 by a fluidic connection.
On the bidet washing apparatus, 100 can be mounted a nozzle assembly 101, which includes
at least one washing nozzle (not shown) for washing the body parts of the user sitting
on or near the toilet bowl 110. The body of the bidet washing apparatus can be made
of any suitable material, including but not limited to, plastics, polymers, reinforced
polymeric materials, wood, metal and the like, and any combination thereof.
[0049] FIG. 3 shows one exemplary embodiment of a bidet washing apparatus 100 with two washing
nozzles 101a and 101b, respectively. However, in an installation, a lesser or greater
number of nozzles can be used. Each washing nozzle can spray a stream of water upwardly
and inwardly, according to various embodiments.
[0050] As shown in FIG. 2 and FIG. 3, a control unit 108 can be provided the easy access
for the user, and houses control switches 102a and 102b for providing operational
instructions to the bidet washing apparatus 100. The depicted example shows two switches
102a and 102b; however, one of ordinary skill in the art would realize that any number
of switches can be provided for performing various operations without departing from
the scope of the disclosure. Some examples of operational instructions include, but
are not limited to, controlling the flow of water from the water inlet, changing the
angle of the washing nozzles, and opening and closing the protective shield gate (described
in further detail below). The type of control switches can be selected from a group
including knobs, dials, levers, depressible buttons, or any conventional control mechanism,
An installation may have all similar control switches where both control switches
102a and 102b are knobs.
[0051] On the other hand, FIG. 9 shows an embodiment of the disclosure where one of the
control switches 102b is a knob and the other control switch 102c is a lever.
[0052] Furthermore, as shown in FIG. 1 and FIG. 2, the nozzle assembly 101 can have a protective
shield gate 104 substantially or partially in front of it. The position of the protective
shield gate 104 is such that it can act as a shield between the user's body and/or
water in the toilet bowl 110 and the nozzle assembly 101 thus protecting the nozzle
assembly 101 from pollutants during use.
[0053] Certain aspects of the bidet washing apparatus will be detailed hereinafter concerning
FIGS. 3-9.
[0054] FIG. 3 shows a front perspective view of one embodiment described herein. Referring
to FIG. 3, the bidet washing apparatus 100 includes the water inlets 103a and 103b
to feed water into the bidet. The water inlet can be controlled by the user using
the control switches 102a and 102b situated on the control unit 108. The water from
the water inlets 103a and 103b can be ultimately provided to the nozzle assembly 101
via tubes (as described in greater detail concerning FIG. 7, for example). The nozzle
assembly shown in this aspect of the disclosure has two washing nozzles 101a and 101b.
The protective shield gate 104 protects the nozzle assembly 101 from excrement and
pollutants as described above. In this example, the protective shield gate 104 is
positioned in front of the nozzle assembly 101 of the bidet such that it is between
the user sitting on the toilet seat, for example, and the nozzle assembly. Hence,
when the user is using, the toilet, the nozzles are shielded behind the protective
shield gate 104 and do not become polluted.
[0055] Referring to FIGS. 5-6, the protective shield gate 104 can be movable along a hinged
edge 111 to provide for further hygiene. The protective shield gate 104 rotates and
thus can be manual, for example, opened (FIG. 6) and closed (FIG. 5), after using
the toilet to clean any minute leftover pollutants on the outer covering of the nozzle
assembly to ensure complete cleanliness. In the embodiment, the user can open and
close the gate manually and, thus, the gate can stay in the opened or closed position
that the user places the gate. In certain embodiments, the gate can be opened and
dosed by an electrical signal using a control switch located on the control unit 108,
which can allow the gate to remain open until the user closes the gate via the control
switch, so the user can clean the nozzle. In other embodiments, the hinged edge 111
is on the top of the protective shield gate 104, and not, on the side edge as shown
in the illustrative FIGS. 5-6. hi. yet other embodiments, the user may be able to
completely remove the protective shield gate 104 for cleaning the nozzle(s) and reattach
it after cleaning. Of course, one of ordinary skill in the art would understand that
the hinged edge could comprise any rotatable joint mechanism that allows for, the
rotation of the protective shield gate 104 to provide efficient access to the nozzle(s).
If the protective shield gate 104 is completely removable, a grooved and slideable
mechanism can be employed so that the protective shield gate 104 can slide in and
out to be attached and removed. Of course, other mechanisms can be utilized for removably
attaching the protective shield gate 104, e.g., a magnet or a snap structure.
[0056] In certain embodiments, the protective shield gate 104 has a flap portion perpendicular
to the protective shield gate 104 such that it covers the bottom of the nozzle assembly
101. Additionally, the flap can have a spring mechanism such that it is pushed out
and aligns with the protective shield gate 104 by the force of the water stream when
water flows out of the nozzle assembly 101. When the water flow stops, the flap can
spring hack into its original position perpendicular to the shield gate 101.
[0057] The protective shield gate 104 of the disclosure can be made from a material selected
from plastic, metal, a material having anti-microbial properties, and material with
increased pollutant repellant properties.
[0058] In certain embodiments, the angle of the washing noz7ies can be adjusted using a
control switch located on the control unit 108. Thus, when a user wants to clean certain
body parts, water can be sprayed on the desired body part by adjusting the angle of
the washing nozzle(s). As shown in FIG. 3, the height of the protective shield gate
is such that it allows for an uninterrupted spray of water from the nozzle assembly
101, since the nozzle assembly 101 can extend beyond the bottom edge of the protective
shield gate 104.
[0059] FIG. 4 shows another embodiment wherein the height of the protective shield gate
is equal to or greater than that of the washing nozzles 101a and 101b. Here, the washing
nozzles 101a and 101b are housed within an outer covering including a spring mechanism
for pushing the washing nozzles out when water flows through the washing nozzles such
that the water flow is not interrupted by the protective shield gate 104. Each washing
nozzle includes an outer covering and an inner nozzle operated slidably hack and firth
with hydraulic pressure of the supplied washing water by an instruction from the control
unit 108. During the use of the washing nozzles, the nozzles are extended from their
outer covering below the length of the shield gate by the hydraulic force of the washing
water, and water is sprayed on the user for cleaning purposes. After use, when the
water flow is stopped, the nozzles are retracted in their outer covering which is
hidden behind the shield gate. In certain other embodiments, the user may control
the movement of the washing nozzle by using the control unit 108, instead of the hydraulic
pressure. When an instruction of a washing operation is given by the control unit
108, a washing nozzle driving unit is activated to advance the nozzle. The washing
nozzle angle can also be adjusted by an instruction given by the control unit 108
to position the nozzle for cleaning. Thus, the washing nozzle can reach the user's
desired washing position by the combined advancement of the nozzle and/or the angular
positioning.
[0060] According to the embodiment, nozzle assembly 101 includes at least one washing nozzle
in yet another embodiment, the bidet washing apparatus 100 further includes a self-cleaning
cleaning nozzle for cleaning the nozzle assembly itself. The self-cleaning nozzle
can be positioned to spray water onto the nozzle assembly 101 and/or washing nozzle(s)
before and/or after the usage for additional hygiene. The self-cleaning nozzle can
be adapted to be controlled by the control unit 108, and thus provides an additional
hygiene level.
[0061] Another embodiment includes a toilet cleaning nozzle fur cleaning the toilet and
the bidet before and after use of the toilet. The toilet cleaning nozzle can be positioned
to spray water on the toilet bowl 110 and/or the bidet washing apparatus 100 and can
be controlled by the control unit to provide additional hygiene. Yet, another embodiment
includes a shield cleaning nozzle for cleaning the protective shield gate 104. The
shield cleaning nozzle can be similarly controlled by the control unit 108. Additionally,
the shield cleaning nozzle can be positioned to clean the protective shield gate 104
in an open and/or closed position.
[0062] Any or all of the washing nozzles can be connected to the nozzle assembly 101 via
a ball joint, for example. which could allow the user to manually swivel a washing
nozzle around 360 degrees, to direct the spray of water in a desired and precise direction.
Of course, other types of joints and connectors could be implemented to allow for
the manual swivel or direction correction, as desired by the user to spray water to
the desired body part, for example. Moreover, according to an exemplary embodiment,
e or more of the washing nozzle(s) 101a and 101b can be connected to the nozzle assembly
101 by a mechanism allowing for the easy removal of the nozzle(s) 101a and 101b. For
example, the washing nozzle(s) 101a and 101b can slide into place via a grooved portion
of the nozzle assembly 101 or could otherwise snap into place. Any conventional mechanism
of removably attaching the nozzle(s) 101a and 101b can be implemented, so that the
user can swap the nozzle(s) 101a and 101b with other nozzles or increase or reduce
the number of washing nozzle(s) 101a and 101b connected to the nozzle assembly 101.
[0063] An exemplary water supply system to the nozzle assembly 101 will be detailed hereinafter
concerning FIGS. 7-8. The control unit 108 can house the control valves 106a and 106b
(as shown in FIG. 8), to control the flow of water to the water tubes and has the
control switches 102a and 102b, for giving instructions to the control valves. Two
control valves and control switches are depicted for exemplary purposes, but it should
be understood that any number of control valves and corresponding switches can be
employed.
[0064] The control valves 106a and 106b can be situated at the entrance to the water tubes
107a, 107b, and 107c in this example. The control valves 106a and 106b are designed
to open, close, or partially obstruct the water inlet 103a opening into the water
tubes 107a, 107b, and 107c, such that the volume of the water flowing through any
tube at any given time can be easily controlled by the user by giving simple instructions
through the control switches. The water tubes 107a, 107b, and 107c connect the control
valves 106a and 106b at one end to the nozzle assembly 101 at the other end. Thus,
the control valves 106a and 106b can effectively control the volume of water flowing
to the nozzle assembly 101. In the embodiment, one water tube 107b passes through
the back of the bidet washing apparatus 100, and two water tubes 107a and 107c pass
through the front of the bidet washing apparatus 100. However, it is to be noted that
in an embodiment, more than one water tube could pass through the back of the bidet
washing apparatus 100, and the number of water tubes passing through the front of
the bidet washing apparatus 100 could be more or less than two.
[0065] According to an embodiment, the bidet washing apparatus 100 can include a vacuum
breaker (not depicted), which can be situated at various locations within the bidet
washing apparatus 100. The vacuum breaker can be located anywhere between the water
supply (e.g., the water tank supplying water to the toilet bowl) and the washing nozzle(s)
e.g., 101a and 101b) output. The vacuum breaker can be intended to halt the flow of
water that is not expelled by the washing nozzle(s) back into the water supply. According
to one exemplary embodiment, the vacuum breaker(s) can be housed within the control
unit 108, located between a valve 106a and 106b and the nozzle assembly 101; however,
one of ordinary skill in the art would realize that various locations of one or more
vacuum breakers can be implemented within the scope of this disclosure to perform
the desired function.
[0066] In one exemplary embodiment, each water inlet 103a and 103b is connected to a control
valve 106a and 106b by a single, non-jointed, connection 115 (see FIG. 10) thereby
removing any intervening parts and extra connections, which can considerably increase
the durability and lifetime of the bidet system. Of course, multiple water inlets
103a and 103b could be connected to a single control valve; however, each connection
between the water inlets 103a and 103b and the single control valve can be a single-body
structure, according to one embodiment.
[0067] In an embodiment, the washing nozzle can be replaced with a nozzle that is configured
to hold materials such as soap, disinfectant, or any cleaning or medicinal, a substance
that can be expelled along with water as it flows through the nozzle. For example,
such materials could be in a solid, semi-solid, or liquid form, which dissolves at
a predetermined and desired rate, as the water flows through the nozzle and is carried
out of the nozzle by the spraying water.
[0068] In another embodiment, the bidet washing apparatus can contain one or more reservoir
dispensers or chambers, which can be configured to hold materials such as soap, disinfectant,
or any cleaning or medicinal substance that can be expelled along with water through
one or more water tubes to the nozzle assembly and car be carried out of one or more
nozzles by the spraying water. As before, the above-mentioned materials are provided
merely for exemplary purposes and are not intended to limit the disclosure in any
way. Other known substances and/or materials could be held and/or stored in a nozzle
or reservoir dispenser to be expelled with water through the nozzle.

[0088] FIG. 22 illustrates an embodiment of a reservoir dispenser lid with a built-in check
valve system 131 and air vent 132 for securing the reservoir dispenser of a bidet
washing apparatus.
[0089] A check valve (clack valve, non-return valve, reflux valve, retention valve, or a
one-way valve) is a valve that normally allows fluid to flow through it in only one
direction. Check valves are two-port valves, meaning they have two openings in the
body, one for air or fluid to enter and the other for air or fluid to leave. Check
valves work automatically and are not controlled by a person or any external control;
accordingly, most check valves do not have any valve handle or stem. The bodies (external
shells) of most check valves are typically made of plastic or metal but can be made
of any suitable material.
[0090] A reservoir dispenser lid with a built-in check valve allows the reservoir dispenser
system described herein to vent when the bidet washing apparatus is not in use. A
check valve allows the flow of air or liquid in one direction but not in the other
direction. In this case, the lid allows air into the lid (venting the disinfectant/soap
reservoir) when the bidet is not in use. When the bidet is in use, the reservoir will
be pressurized with water, but no liquid can flow out of the lid. This allows the
water-filled in the disinfectant/soap reservoir to be flushed out at the end of each
use. It is necessary to flush the water in the reservoir because the chemical ingredients
of the disinfectant/soap can grow mold and/or dissolve if water is present in the
reservoir for a prolonged period.
[0091] An important concept in check valves is the cracking pressure (unseating head pressure
or opening pressure), which is the minimum differential upstream pressure inlet and
at which the valve will operate. Typically, the check valve is designed for and can
be specified for a specific cracking pressure. Reseal pressure (sealing pressure,
seating pressure, seating head pressure, or closing pressure) refers to the pressure
differential between the inlet and outlet of the valve during the closing process
of the check valve, at which there is no visible leak rate.
[0092] Backpressure refers to a pressure higher at the outlet of a fitting than that at
the inlet or a point upstream.
[0093] A ball check valve in the open position allows forward flow and the closed position,
allows the device to block reverse flow. A ball check valve is a check valve in which
the closing member, the movable part to block the flow, is a ball. In some ball check
valves, the ball can be spring-loaded to help keep it shut. For those designs without
a spring, reverse flow is required to move the ball toward the seat and create a seal.
The interior surface of the main seats of ball check valves is more or less conically
tapered to guide the ball into the seat and form a positive seal when stopping reverse
flow.
[0094] By contrast, a diaphragm check valve uses a flexing rubber diaphragm positioned to
create a normally closed valve. Pressure on the upstream side must be greater than
the pressure on the downstream side by a certain amount known as the pressure differential,
for the check valve to open allowing flow. Once positive pressure stops, the diaphragm
automatically flexes back to its original closed position.
[0095] FIG. 23 illustrates an embodiment of reservoir dispenser lid with a built-in check
valve system 131 and air vent 132 for securing to the reservoir dispenser 120, the
control unit 108, control switches 102a and 102b of a bidet washing apparatus 100.
The soap container (not shown) in the reservoir dispenser can be secured within the
control panel using screws. As shown, the lid with the built-in check valve system
131 can be exposed for easy removal.
[0096] FIG. 24 illustrates an embodiment of a reservoir dispenser lid 121 with a built-in
check valve system 131 and air vent 132 secured to the reservoir dispenser 120 by
being screwed onto or attached to the dispenser, i.e., the lid and dispenser can be
threaded together, and the lid and dispenser can be snapped together.
[0097] FIG. 25A illustrates an embodiment of the exterior view of the reservoir dispenser
lid 121 with a built-in check valve system 131 and air vent 132; and FIG. 25B illustrates
an embodiment of a cut-away view of the reservoir dispenser lid 121 and air vent 132.
As shown, the inside top of the reservoir dispenser lid 121 can include a check valve
133 and a moveable rubber disk 134, which can be secured to the reservoir dispenser
lid 121 via a complementary lip 135.
[0098] FIG. 26 illustrates an embodiment of the reservoir dispenser lid 121 with a built-in
check valve 133 having moveable rubber disk 134. As shown in this figure, air can
flow through the valve via air vent openings 136.
[0099] FIG. 27 illustrates an embodiment of a cut-away cross-sectional view of a reservoir
dispenser lid with a built-in check valve system 131 and air vent 132. As shown, air
can flow into the lid and the reservoir dispenser 120 through air vent 132 and air
vent openings 136. That is the movable rubber disk 134 of the check valve 133 is in
the open position, which allows air to enter the reservoir dispenser through the air
vent of the lid.
[0100] FIG. 28 illustrates an embodiment of a cut-away cross-sectional view of a reservoir
dispenser lid with a built-in check valve system 131 and air vent 132. As shown, air
cannot flow into the lid and, into the reservoir dispenser 120 through air vent 132
because it is blocked by the movable rubber disk 134. That is, the movable rubber
disk 134 of the check valve 133 is in the closed position due to the high internal
pressure of the water pushing up against the rubber disk, which prevents air from
entering the reservoir dispenser through the air vent of, the lid and prevents, any
liquid from escaping.
[0101] In other embodiments, the disclosure provides a reservoir dispenser for a bidet washing
apparatus having a plurality of chambers, wherein a first chamber holds a liquid wash
solution, and a second chamber holds water for flow through the apparatus. In these
embodiments, the liquid wash solution from the first chamber can be added to the water
present in the second chamber and mixed therein, in a controlled, measured manner
without backflow of water into the first chamber.
[0102] It is understood by those of skill in the art that the phrase "liquid wash solution"
is meant in a non-limiting sense and can include any combination of soap or detergent
in a solution of water along with other additives. Additives in this type of solution
can include but are not limited to disinfectants, antibacterial, anti-inflammatory,
moisturizing, antiseptic, anti-fungal, germicidal, soothing, detoxifying, cooling,
antipruritic, hydrating, antiviral, cleansing, cleaning, and deodorizing additives,
or a combination thereof.
[0103] FIG. 29 illustrates an embodiment of such a reservoir dispenser 120, which uses a
bottom check valve (not shown) between the first chamber 151 and the second chamber
152 and a side check valve (not shown) present in the first chamber for control of
a liquid wash solution without backflow.
[0104] In some embodiments, the reservoir dispenser 120 can include a lid 121, which can
be attached to the first chamber 151. In embodiments, the lid can be permanently or
reversibly attachable to the first chamber. Included within the lid 121 is an opening
150, in which a means for activation such as an activator 153 can fill and protrude
therethrough. In some embodiments, the opening 150 can be centrally located within
the lid 121.
[0105] As used herein, an "activator" includes but is not limited to a push-button, twist-button,
pull up and push down button, a slide button, a plunger button, a lever, a knob, or
other similar devices.
[0106] In embodiments, the activator 153 can be engaged by manually pushing it downwards
to allow for the introduction of the liquid wash solution present in the first chamber
151 to pass through the bottom check valve and into the second chamber 152.
[0107] Also shown in this figure is a securing mechanism or tab 126 for attaching the reservoir
dispenser to a bidet washing apparatus (not shown); and a water inlet 123 and water
outlet 125 for the second chamber 152, which allows water to flow into and out of
the second chamber, respectively.
[0108] FIG. 30 illustrates an embodiment of a side cut-away view of the reservoir dispenser
120 as per FIG. 29. As shown in this figure, the reservoir dispenser 120 includes
the first chamber 151 and the second chamber 152, wherein the first chamber extends
down into the second chamber. As shown, the second chamber 152 includes a base platform
164, which can secure a hollow barrel 157 that extends from the base platform 164
in the second chamber to the base of the lid (lid base) 172 in the first chamber 151.
At the lower end of the barrel in the second chamber, the barrel 157 includes two
O-rings 167a and 167b, which act to seal these chambers. The activator 153 is present
within the opening 150 of the lid 121 and extends down into the first chamber 151
through a stem 154 and a distal stem endpiece 155. The barrel 157 surrounds stem 154
and stem endpiece 155 and runs between the first chamber 151 and the second chamber
152. Surrounding a mid to upper region of the stem 154 is one or more O-rings 167c,
which acts to seal the stem 154 against the lid base 172 when the activator 153 is
in the inactivated position, i.e., the up position. Also shown are the water inlet
123 and the securing mechanism 126, which are connected to the second chamber 152.
[0109] As shown in this figure, lid 121 can include a lid lip 165, which surrounds the opening
150, and is designed to engage with and secure the activator 153 through a complimentary
activator lip 166. The lid base 172 separates the lid 121 from the first chamber 151
and acts to support a spring 173 for resistance to the activator 153. The activator
153 and the activator lip 166 are designed to move up and down within the space between
the inner wall 174 and outer wall 175 of the lid base 172.
[0110] The first chamber 151 can be reversibly connected to the lid 121 through a screw-on,
threaded type mechanism 168a, or can be snapped on, or can be secured permanently
or reversibly or by any other means known in the art. In addition, a gasket 185 can
be used between the first chamber 151 and the lid 121, which prevents leakage of the
liquid wash solution present in the first chamber 151.
[0111] The lid base 172 can also be reversibly connected to the lid 121 through a screw-on,
threaded type mechanism 168b, or can be snapped on, or can be secured permanently
or reversibly or by any other means known in the art.
[0112] Further, the second chamber 152 can be reversibly connected to the first chamber
151 through a screw-on, threaded type mechanism 168c, or can be snapped on, or can
be secured permanently or reversibly or by any other means known in the art. In addition,
an O-ring (not shown) can be used between the second chamber 152 and the first chamber
151, which prevents leakage of the water present in the second chamber 152.
[0113] As described herein, the bottom check valve 158 can be an inline-type check valve,
which includes a check valve housing unit 176 that is surrounded by an O-ring 167d.
Included within the housing unit is a check valve disc 159 and O-ring 167e, a check
valve spring 160, and a check valve guide 161 having one or more openings 162 therethrough.
The additional components of the bottom check valve 158 are made up of the stem endpiece
155 and inner sidewalls 163 of the barrel 157.

valve 158 includes the check valve housing 176 and O-ring 167d. The additional components
of the bottom check valve 158 are made up of the check valve disc 159, check valve
spring 160, check valve guide 161 and openings 162 therethrough, and the stem endpiece
155 and inner sidewalls 163 of the barrel 157 as described above. Also shown in this
figure is the side check valve 177, which includes the sidearm 188, the ball 178,
the seat 179, the opening 180 into the barrel 157, and the opening 181 to the first
chamber 151 (not shown).
[0123] FIG. 38 illustrates an embodiment of an exploded top side view of the bottom check
valve 158. As shown in this figure, check valve 158 includes housing 176, disc 159,
spring 160, and guide 161 with openings 162.
[0124] FIG. 39 illustrates an embodiment of a cut-away side view of the housing assembly
192. As shown in this figure, assembly 192 includes the first chamber 151, which extends
down into the second chamber 152 with space and support 193 for the bottom check valve
158 including the housing 176, and space and support 194 for the side check valve
177 and sidearm 188 of the barrel 157.
[0125] A check valve allows the flow of liquid in one direction. Typically, a check valve
has two openings: a check valve input side, and a check valve output side. Since a
check valve only allows fluid to flow in one direction, they are commonly referred
to as 'one-way valves or 'nonreturn valves.' The main purpose of a check valve is
to prevent backflow into the system. A check valve device relies on a pressure differential
to work. They require a higher pressure (cracking pressure) on the input side than
the output side to open the valve. When the pressure is higher on the outlet side,
the valve will close. Depending on the valve type, the closing mechanism can be different.
In short, the back pressure can push a gate, ball, diaphragm, or disc against an orifice
and seal it. Depending on the design, the closing process can be assisted by a spring
or gravity. Common types of check valves include but are not limited to spring-loaded
check valves, diaphragm check valves, umbrella check valves, duckbill check valves,
and others.
[0126] FIG. 40 illustrates an embodiment of a side cut-away view of a reservoir dispenser
120 having a bottom check valve 158 and a side check valve 177 in action.
[0127] As shown in this figure, initially the liquid wash solution present in the first
chamber 151 remains separated from the water in the second chamber 152 by the action
of the check valve 158. The check valve 158 includes the check valve disc 159, which
remains pressed against the sidewalls 163 of the barrel 157 by the action of the check
valve spring 160 and check valve guide 161. The liquid wash solution present in the
first chamber 151 can enter the barrel 157 through the openings 187 present in barrel
157 and the openings 180 and 181 through the side check valve 177 but is stopped from
entering the second chamber 152 by the check valve disc 159 pressing against the sidewalls
163 of the barrel.
[0128] As shown in FIG. 41, downward movement on the activator 153 causes an aliquot of
the liquid wash solution in the first chamber 151 to be trapped between the stem endpiece
155, the sidewalls 163 of the barrel 157, and the check valve disc 159.
[0129] Further downward movement on the activator 153 results in sufficient force or pressure
to overcome the cracking pressure of the check valve 158 and forces the check valve
disc 159 and check valve spring 160 downwards, which allows the trapped aliquot of
the liquid wash solution to flow through the check valve guide 161 and its' openings
162 and into the second chamber 152, whereupon the aliquot of liquid wash solution
is mixed with the water present in this chamber. In addition, the downward pressure
causes the ball 178 to press against the seat 179 and close the opening 180 of the
side check valve 177, which closes off the first chamber 151 from the barrel 157.
Finally, stem 154 can physically cut off the opening 181 of the side check valve 177.
[0130] When the input pressure is no longer high enough on the check valve due to upwards
motion or release of the activator 153, then the backpressure and/or the check valve
spring 160 pushes the check valve disc 159 upwards and against the sidewalls 163 of
the barrel and seals and separates the contents of the first chamber 151 from the
contents of the second chamber 152. The check valve spring 160, along with the short
travel distance for the check valve disc 159, allows for quick reaction times for
opening and closing. Also, the reduced pressure in barrel 157 causes the ball 178
to release its position against the seat 179 in the side check valve 177, which allows
openings 180 and 181 to allow the flow of liquid wash solution in the first chamber
151 to enter into the barrel 157.
[0131] In other embodiments, the disclosure provides another reservoir dispenser for a bidet
washing apparatus having a plurality of chambers, wherein a first chamber holds a
liquid wash solution, and a second chamber holds water for flow through the apparatus.
Similarly, in these embodiments, the liquid wash solution from the first chamber can
be added to the water present in the second chamber and mixed therein, in a controlled,
measured manner without backflow of water into the first chamber.
[0132] FIG. 42 illustrates another embodiment of a side cut-away view of the reservoir dispenser
120, in particular in an inactivated position. As shown in this figure, reservoir
dispenser 120 includes a first chamber 151 and a second chamber 152. An activator
153 is present within an opening 150 of the lid 121 and extends into the first chamber
151 through a hollow upper tube 200. The upper tube 200 includes a side arm 201 that
is connected to a supply tube inlet 202 that runs into the first chamber 151 where
a liquid wash solution can be stored.
[0133] The first chamber 151 can be reversibly connected to the lid 121 through a screw-on,
threaded type mechanism 168a, or can be snapped on, or can be secured permanently
or reversibly or by any other means known in the art. In addition, an O-ring (not
shown) can be used between the first chamber 151 and the lid 121, which prevents leakage
of the liquid wash solution present in the first chamber 151. In addition, the first
chamber 151 can be reversibly connected to the second chamber 152 through a similar
mechanism 168d and O-ring 167k.
[0134] As shown, the upper tube 200 expands into a pump chamber lid 203 below the sidearm
201. Directly beneath the pump chamber lid 203, lies a pump chamber receptacle 204.
Together, the pump chamber lid 203 and the pump chamber receptacle 204 can together
form a pump chamber 205. In some embodiments, the pump chamber lid 203 can encompass
and slide upon the pump chamber receptacle 204, whereas in other embodiments, the
pump chamber receptacle 204 can encompass and slide upon the pump chamber lid 203.
In either event, the pump chamber lid 203 and the pump chamber receptacle 204 form
the pump chamber 205. As shown, the pump chamber receptacle 204 extends downwards
through a support base 206, which encircles a hollow upper first tube 207. Below the
support base 206 lies an outlet chamber 208 and a hollow lower second tube 209, which
can be secured to the base 210 of the first chamber 151. As shown, the upper first
tube 207, outlet chamber 208, and the lower second tube 209 are in communication with
each other.
[0135] Within the pump chamber 205 is a spring 211 and first ball 212, which can be located
between the support base 206 and an inside top of the pump chamber lid 203. Within
the outlet chamber 208, which is wider than the upper first tube 207 and the lower
second tube 209, is a second ball 213, which can toggle between the support base 206
and the lower second tube 209.
[0136] The lower second tube 209 can be reversibly connected to the base 210 of the first
chamber through a screw-on, threaded type mechanism 168c, or can be snapped on, or
can be secured permanently or reversibly or by any other means known in the art. In
addition, an O-ring 167h can be used between the outlet and the base, which prevents
leakage of the liquid wash solution present in the first chamber.
[0137] FIG. 43 illustrates another embodiment of a side cut-away view of the pump mechanism
present in the first chamber, in particular in an activated position. The pump mechanism
includes the activator 153, upper tube 200, sidearm 201, supply tube inlet 202, pump
chamber lid 203, pump chamber receptacle, pump chamber 205, spring 211, first ball
212, support base 206, upper first tube 207, outlet chamber 208, second ball 213,
and the lower second tube 209.
[0138] FIGs. 42 and 43 illustrate an embodiment of a side cut-away view of a reservoir dispenser
120 having a pump chamber 205 in action.
[0139] As shown in FIG. 42, initially the liquid wash solution present in the first chamber
151 remains separate from the water in the second chamber 152 by the action of the
pump mechanism. That is, before engaging the activator 153, the higher pressure in
the outlet chamber 208 due to the running water in the second chamber 152, forces
the second ball 213 upwards against the support base 206, which closes off the outlet
chamber 208 (and second chamber) from the pump chamber 205 (and first chamber).
[0140] As shown in FIG. 43, when the activator 153 is engaged by pushing it downwards, the
pump chamber lid 203 slides down the pump chamber receptacle 204, and the pump chamber
205, holding the liquid wash solution decreases in volume. This decrease in volume
gives rise to a corresponding increase in pressure in the pump chamber 205. The spring
211 present in the pump chamber 205, compresses against the support base 206 and the
first ball 212 is forced against the opening to the upper tube 200. This effectively
seals off the pump chamber 205 from the hollow upper tube 200 and first chamber, which
prevents the liquid soap solution present in the pump chamber from returning to the
first chamber 151. Furthermore, the increased pressure in the pump chamber 205 forces
the second ball 213 downwards in the outlet chamber 208, which allows the liquid wash
solution present in the pump chamber 205 to travel down the upper first tube 207 into
the outlet chamber 208, the lower second tube 209, and into the second chamber 152.
[0141] Upon release of the activator 153, the pump chamber lid 203 slides up the pump chamber
receptacle 204, and the pump chamber 205 increases in volume (see FIG. 46). This increase
in volume decreases the pressure in the pump chamber 205. As such, the spring 211
present in the pump chamber 205, elongates against the support base 206 and the first
ball 212 is released from the inside top of the pump chamber lid 203, thereby opening
the pump chamber 205 to the hollow upper tube 200 and first chamber. This allows the
liquid wash solution present in the first chamber 151 to travel through the supply
tube inlet 202 through the sidearm 201 and into the pump chamber 205 due to the reduced
pressure in the pump chamber 205. Furthermore, the greater pressure in the outlet
chamber 208 forces the second ball 213 upwards against the support base 206, which
closes off the outlet chamber (and second chamber) from the pump chamber 205 (and
first chamber).
[0142] In yet more embodiments, the disclosure provides a reservoir dispenser for a bidet
washing apparatus having a plurality of chambers, wherein a first chamber holds a
liquid wash solution, and a second chamber holds water for flow through the apparatus.
Similarly, in these embodiments, the liquid wash solution from the first chamber can
be added to the water present in the second chamber and mixed therein, in a controlled,
measured manner without backflow of water into the first chamber.
[0143] FIGs. 44 and 45 illustrate an embodiment of a side cut-away view of the reservoir
dispenser 120 when in the inactivated and activated position, respectively. As shown
in this figure, the reservoir dispenser includes a first chamber 151 and a second
chamber 152, and a lid 121, which is attachable to the first chamber.
[0144] Between the first chamber 151 and the second chamber 152 is a support holder 300,
in which the first chamber is supported by and tracks or slides up and down upon.
As described herein, the sliding action of the first chamber 151 into the support
holder 300 serves to activate the pump mechanism, i.e., it's an activator. The support
holder 300 includes a support holder chamber 301, which is attached to the support
holder base 302. The first chamber 151 includes a pump holder 303, which is encapsulated
and surrounded by an inner wall 304, an outer wall 305, and a top wall or ceiling
306 between these walls. The space 307 between the inner and outer walls can act as
a track for the support holder chamber 301 to track or slide upon. The second chamber
152 acts to secure the support holder 300. A seal 308 underneath the support holder
base 302 prevents backflow of water from the second chamber.
[0145] The support holder base 302 can secure a closed-ended outlet tube 310, which can
run up from the second chamber 152, through the support holder base 302 through the
support holder chamber 301 and the pump holder 303. Surrounding the outlet tube 310
is a pump housing unit 311, which is secured to the pump holder 303 and surrounds
the hollow tube. The outlet tube 310 includes a grooved region 312 having a proximal
end 313 and a distal end 314, in which a piston 315 can be attached to and allowed
to travel along this grooved region. The closed-ended outlet tube 310 also includes
one or more holes or openings 316 located in the proximity of the groove 312 and piston
315, such that the piston can slide along the groove to uncover (at the distal end
314) and cover (at the proximal end 313) the holes or openings in the hollow tube,
for example, when the activator 153 is pushed down and when the activator is released
upwards, respectively. The outlet tube 310 can include two O-rings 167i and 167j,
which acts to prevent leakage of the liquid wash solution from the first chamber 151,
the support holder 300, and/or the second chamber 152. Also included within the pump
housing unit 311 is a ball 317 and a spring 318, which together with the outlet tube
310 can act as a check valve as described herein. Above the ball 317 and spring 318,
the pump housing unit 311 is attached to a hollow U-shaped inlet tube 319, which travels
from the pump housing unit 311 into the first chamber 151 to access the liquid wash
solution contained therein.
[0146] FIG. 46 illustrates an embodiment of a cut-away view of the reservoir dispenser 121
showing the first chamber 151, support holder 300, and the second chamber 151 without
the pump mechanism 320. Also shown are the lid 121, pump holder 303, inner wall 304,
outer wall 305, ceiling 306, space 307, support holder chamber 301, and the support
holder base 302.
[0147] FIGs. 47 and 48 illustrate an embodiment of a view of the pump mechanism 320, showing
the piston 315 in the proximal end 313 of the groove 312, which covers the holes or
openings 316 in the outlet tube 310; and the piston 315 in the distal end 314 of the
groove 312, which uncovers the holes or openings 316 in the outlet tube 310. Also
shown in these figures are the pump housing unit 311, spring 318, ball 317, O-rings
167i and 167j, and the U-shaped inlet tube 319.
[0148] FIGs. 44 and 45 illustrate an embodiment of a side cut-away view of a reservoir dispenser
120. As shown in FIG. 44, initially the liquid wash solution present in the first
chamber 151 remains separate from the water in the second chamber 152 by the action
of the pump mechanism. That is, before engaging the pump mechanism by pushing down
on the lid 121 and first chamber 151, i.e., the activator 153, the piston 315 surrounding
the outlet tube 310 is located at the proximal end 313 of the groove 312, which covers
the holes or openings 316 in the outlet tube 310. As such, there is no connection
between the first chamber 151 and the second chamber 152.
[0149] When the activator 153 is pressed, i.e., the lid 121 and first chamber 151 as explained
above, the pump holder 303 is forced down upon the inner cup chamber holder 304 by
sliding or tracking down into the space 307 between the inner wall 304 and outer wall
305 of the pump holder 303. The spring 318 on top of the outlet tube 310 is compressed,
which forces the ball 317 against the upper walls 321 of the pump housing unit 311,
which closes access between the pump holder 303 and the first chamber 151. At the
same time, the piston 315 moves from a proximal end 313 to a distal end 314 of the
groove 312, which uncovers the holes or openings 316 present in the outlet tube 310
and allows the pressurized liquid wash solution present in the pump housing unit 311
to enter the outlet tube 310 through the holes or openings 316 and pass into the second
chamber 152.
[0150] As shown in FIG. 45, conversely when the activator 153 is released, i.e., the lid
121 and first chamber 151 as explained above, the pump holder 303 moves up on the
support holder chamber 301. The spring 318 on top of the outlet tube 310 is allowed
to elongate, which allows the ball 317 to be released from the upper walls 321 of
the pump housing unit 311. This allows access between the pump holder 303 and the
first chamber 151. At the same time, the piston 315 moves from the distal end 314
to the proximal end 313 of the groove 312, which covers the holes or openings in the
outlet tube 310 and prevents the liquid wash solution present in the pump housing
unit 311 from entering the outlet tube 310 and pass into the second chamber 152.
