Bidet washing apparatus with disinfectant wash feature

FIELD OF THE INVENTION

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

A bidet apparatus for washing and cleaning body parts. e.g., genital and/or anal, was 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 were 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 sitting on it, using washing water sprayed from the bidet nozzles, without the use of toilet paper. Such bidets can include a plurality of nozzles for washing the private parts as well as the bidet itself.

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 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.

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.

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, the one or more valves can control water flow from the 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. The at least one washing nozzle can be positioned for directing water to the one or more body parts of the user. The apparatus can also include a protective shield gate covering at least a portion of the at least one washing nozzle, where the protective shield gate is rotatably coupled to the bidet washing apparatus.

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, in order 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 other 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).

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.

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 mechanism 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, the 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 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.

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.

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, and depressible buttons, or any conventional control mechanism, An installation may have all similar control switches where both control switches 102a and 102b are knobs.

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.

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.

Certain aspects of the bidet washing apparatus will be detailed hereinafter with reference to FIGS. 3-9.

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 with reference to 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.

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 manually, for example, opened (FIG. 6) and closed (FIG. 5), after using the toilet to clean any minute left over 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 gale 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.

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.

The protective shield gate 104 of the disclosure can be made from a material selected from plastic, metal, material having anti-microbial properties, and material with increased pollutant repellant properties.

In certain embodiments, the angle of the washing nozzles can be adjusted using control switche(s) located on the control unit 108. Thus, when a user wants to clean certain body parts, water can be sprayed on a 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.

FIG. 4 shows another embodiment wherein the height 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 push ng 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 as inner nozzle operated slidably hack and firth with hydraulic pressure of the supplied washing water in accordance with an instruction from the control unit 108. During 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 10$, 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.

According to the embodiment, the 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 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.

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.

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, in order to direct the spray of water in a desired and precise direction. Of course, other types of joints and connectors could be implemented in order to allow for the manual swivel or direction correction, as desired by the user to spray water to a 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.

An exemplary water supply system to the nozzle assembly 101 will be detailed hereinafter with reference to 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.

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 the any tube at any given time can be easily controlled by the user by giving simple instructions thorough 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 N 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.

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.

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.

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, 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.

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 in order to be expelled with water through the nozzle.

FIG. 11 illustrates a cut-away view of an embodiment of a top view of a bidet washing apparatus 100, i.e., without showing the entire body of the apparatus. In this figure, the apparatus includes water inlet 103a, which is fluidically connected to control unit 108 to supply water. The control unit includes control unit switch 102a, which is configured to operate one or more control unit valves or openings (not shown) for controlling water flow from the water inlet and from control unit outlets 122a and 122b.

As shown in this figure, the apparatus also includes a reservoir dispenser 120 having one or more compartments (not shown) with a removable lid or cap 121 for holding soap and/or disinfectant.

FIG. 22 illustrates an embodiment of a reservoir dispenser cap with a built-in check valve system 131 and air vent 132 for securing the reservoir dispenser of a bidet washing apparatus.

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.

A reservoir dispenser cap 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 flow of air or liquid in one direction but not in the other directions. In this case, the cap allows air into the cap (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 cap. 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 present in the reservoir for a prolonged period of time.

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. Back pressure refers to a pressure higher at the outlet of a fitting than that at the inlet or a point upstream.

A ball check valve the open position allows forward flow and its 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 are more or less conically tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.

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.

FIG. 23 illustrates an embodiment of reservoir dispenser cap with a built-it 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 in this figure, the cap with the built-in check valve system 131 can be exposed for easy removal.

FIG. 24 illustrates an embodiment of a reservoir dispenser cap 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 cap and dispenser can be threaded together and the cap and dispenser can snapped together.

FIG. 25A illustrates an embodiment of the exterior view of the reservoir dispenser lid or cap 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 or cap 121 and air vent 132. As shown in this figure, the inside top of the reservoir dispenser lid or cap 121 includes a check valve 133 and a moveable rubber disk 134, which can be secured to the reservoir dispenser lid or cap 121 via a complementary lip 135.

FIG. 26 illustrates an embodiment of the reservoir dispenser lid or cap 121 with a built-in check valve 133 having moveable rubber disk 134. As show this figure, air can flow through the valve via air vent openings 136.

FIG. 27 illustrates an embodiment of a cut-away cross-sectional view of a reservoir dispenser cap with a built-in check valve system 131 and air vent 132. As shown in this figure, air can flow into the cap and the reservoir dispenser device 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 device through the air vent of the cap.

FIG. 28 illustrates an embodiment of a cut-away cross-sectional view of a reservoir dispenser cap with a built-in check valve system 131 and air vent 132. As shown in this figure, air cannot flow into the cap and, into the reservoir dispenser device 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 device through the air vent of, the cap and prevents, any liquid from escaping.

As a result of the foregoing description, a bidet washing apparatus is provided with an objective of satisfactorily and, hygienically washing a user's body parts after toilet use.
