Embodiments of the present disclosure relate to a bidet washing apparatus, for use with a toilet bowl, which can provide for the cleaning of body parts of a person sitting on or near the bowl.
One conventional method of cleaning oneself after toilet use is with paper, which is not always available and is sometimes so rough as to aggravate the skin. Moreover, such paper not infrequently causes plumbing problems by clogging up the toilet at the time of flushing.
Bidet apparatus for washing and cleaning the body parts (e.g., genital and/or anal) using water were initially developed in the form of a bidet that provided a single spray of water and was conventionally permanently built into the bowl. However, such bidets were expensive and a new generation of bidets attachable to the toilet was then developed with 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 may include a plurality of nozzles for washing the private parts as well as the bidet itself.
Various designs have addressed some of the desired effects, such as washing, washing with temperature-regulated water, and drying. However, existing bidets fail 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.
Some mobile cleaning and bidet systems may exist which operate according to various techniques in order to overcome these problems. Some such bidets comprising mobile cleaning have an electrical or mechanical system to retract the nozzles within a cylindrical covering to prevent pollution. The nozzle moves forward within the body of the cylinder and becomes active either by electrical or by a mechanical signal. The nozzle is retracted upon usage of the toilet. The mechanical signal acts by the force of the washing water that pushes the nozzle out of its outer covering and thus washing water is sprayed on the person sitting on the toilet. When the washing water supply is stopped, the nozzle is retracted. Therefore, when a user uses the lavatory, the user's excrement is not splattered directly on the nozzle pipes since the nozzle pipes are accommodated within the outer covering. Thus the pollution of the nozzles is prevented to some extent. However, this is not very efficient and does not adequately solve the hygiene related issues.
For example, the nozzle pipes may still become dirty when the user is being washed by the washing water sprayed from the nozzle. Some bidets overcome this by allowing the user to pull out the nozzle manually and clean the nozzle after use. However, this is both cumbersome and unpleasant. Some other bidets have a cleaning nozzle to wash the washing nozzles after usage. However, this is also undesirable because of nozzle positions and dripping of the nozzle cleaning water.
Another problem with the existing bidet systems is the existence of multiple joints between the water inlets and the control valves of the bidet. Such joints are unwieldy and also considerably reduce the life of the bidet because of the possibility of breaking or leakage of one of the numerous joints. It is, thus, desirable to engineer a single connection between a water inlet and a control valve, which conventional bidets have failed to accomplish.
The presently disclosed embodiments are directed to solving one or more of the problems presented in the prior art, described above, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompanying drawings.
Accordingly, one object of the present disclosure is to provide 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 manner, 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 an 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.
Further features and advantages of the present disclosure, as well as the structure and operation of various embodiments of the present disclosure, are described in detail below with reference to the accompanying drawings.

Embodiments disclosed herein describe a new, clean and hygienic washing bidet. Various embodiments comprise 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 inlet(s) 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.
Embodiments of the present disclosure are directed to a 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. As described herein, a “bidet” is a toilet attachment for cleaning the body parts of the user. The term “water inlet” means any structure that may provide water to the bidet washing apparatus. “Control unit” (aka “control panel”) is the housing which has “control switche(s)” thereon controlling the various functionalities of the bidet, including but not limited to, flow of water, adjusting the angle of the nozzles, and opening and closing the protective shield gate. “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. “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 comprising at least one “washing nozzle.” “Nozzle” is a device designed to eject water or other fluids into the surrounding medium as a coherent controlled spray. The “washing nozzle” is the nozzle that can be used to wash the body parts of a user. 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.” 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. The “protective shield gate” can have 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. The term “fluidically coupled” means a connection or a passageway which allows fluid to flow therethrough. The term “reservoir” means a fluid holding tank.

A control unit 108 can be provided for easy access for the user, and houses control switches 102a and 102b for providing operational instructions to the bidet washing apparatus. The depicted example shows two switches 102a and 102b; however, one of ordinary skill in the art would realize that any number of switches may be provided for performing various operations, without departing from the scope of the present disclosure. Some examples of operational instructions are (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 may be selected from a group comprising 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,
Furthermore, as shown in
Certain aspects of the bidet washing apparatus will be detailed hereinafter with reference to

In certain embodiments, the protective shield gate 104 has a flap portion perpendicular to the 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 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 back into its original position perpendicular to the shield gate 101.
The protective shield gate 104 of the present disclosure can be made from a material selected from the group comprising plastic, metal, material having anti-microbial properties, and material with increased pollutant repellant properties.
In certain embodiments, the angle of the washing nozzles may be adjusted using control switche(s) located on the control unit 108. Thus, when a user wants to clean certain body parts, water may be sprayed on a desired body part by adjusting the angle of the washing nozzle(s). In the present embodiment as shown in
According to the present embodiment, the nozzle assembly 101 comprises at least one washing nozzle. In yet another embodiment, the bidet washing apparatus 100 further comprises a self cleaning nozzle for cleaning the nozzle assembly itself. The self cleaning nozzle can be positioned to spray water onto the nozzle assembly 100 and/or washing nozzle(s) before and/or after usage for additional hygiene. The self cleaning nozzle may be adapted to be controlled by the control unit 108, and thus provides an additional hygiene level. Another embodiment comprises a toilet cleaning nozzle for 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 apparatus 100, and may be controlled by the control unit to provide additional hygiene. Yet, another embodiment comprises a shield cleaning nozzle for cleaning the protective shield gate 104. The shield cleaning nozzle may be similarly controlled by the control unit 108. Additionally, the shield cleaning nozzle may be positioned to clean the shield gate 104 in an open and/or closed position.
Any or all of the washing nozzles may 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, one or more of the washing nozzle(s) 101a-101b can be connected to the nozzle assembly 101 by a mechanism allowing for the easy removal of the nozzle(s) 101a-101b. For example, the washing nozzle(s) 101a-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-101b can be implemented, so that the user can swap the nozzle(s) 101a-101b with other nozzles or increase or reduce the number of washing nozzle(s) 101a-101b connected to the nozzle assembly 101.
According to an embodiment, a washing nozzle can be replaced with a nozzle that is configured to hold materials such as soap, disinfectant or any medicinal substance which can be expelled along with water as it flows through the nozzle. For example, such materials could be in a solid 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. The above-mentioned materials are provided merely for exemplary purposes and are not intended to limit the disclosure in any way. Other substances/materials could be held/stored in a nozzle in order to be expelled with water through the nozzle.
An exemplary water supply system to the nozzle assembly 101 will be detailed hereinafter with reference to
The control valves 106a and 106b can be situated at the entrance to the water tubes 107a-107c in this example. The control valves 106a and 106b are designed to open, close or partially obstruct the water inlet 103 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-107c connect the control valves 106a-106b at one end to the nozzle assembly 101 at the other end. Thus the control valves 106a-106b can effectively control the volume of water flowing to the nozzle assembly 101. In the present embodiment, one water tube 107b passes through the back of the bidet 100, and two water tubes 107a and 107c pass through the front of the bidet 100. However, it is to be noted that in an embodiment, more than one water tube could pass through the back of the bidet 100, and the number of water tubes passing through the front of the bidet 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-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-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-103b is connected to a control valve 106a-106b by a single, non-jointed, connection 115 (see
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. The protective shield gate, according to embodiments described herein, can provide advanced hygiene by protecting the nozzle(s) from excrement, while allowing for the easy cleaning and/or replacement of nozzle(s) as desired. Moreover, the single-body design of the connector between the water inlet(s) and the valve(s) provides for enhanced durability of the bidet washing apparatus, with decreased risk of leakage.
