Description

Toilet seat attachment type foot washing device {TOILET BOWL ATTACHABLE FOOT WASHING APPARATUS}

The present invention relates to a toilet seat attachment type foot washing device.

Feet sweat three times more than other parts of the body and have almost no sebaceous glands, so they are prone to dryness or roughness. If you do not take good care of your feet, there is a risk of developing various foot diseases such as athlete's foot.

In particular, when an epidemic virus is spreading or air pollution is severe due to fine dust, you must wash your feet well after going out.

In general, when washing your feet, bend your back and wipe every corner of your feet with your hands so that your hands can reach your feet. Because it is uncomfortable, it can be very difficult to wash your feet yourself.

Accordingly, various products are being released on the market that can help you wash your feet while they are fixed to the floor. Among them, there are foot washing products that are placed around the toilet seat as a chair or attached to the toilet seat so that you can safely wash your feet. Therefore, it is true that it is still far from effective in terms of effectiveness.

In particular, in order to automatically treat sewage, it is recommended to use the sewage outlet of the toilet seat already installed on the floor while paying attention to the inflow of odors. Since it is a blocking structure, there was a problem in that it was difficult to install a sewage pipe when a foot washing product was attached to a sitting toilet.

The present invention has been proposed to solve the above problems, and it is installed in a simple slidable structure under the existing toilet seat to solve the space constraint that was an existing problem, and at the same time, it takes into account the supply of washing water and the discharge of sewage. Accordingly, an object of the present invention is to provide a toilet seat attachment type foot washing device that can provide practicality and convenience.

The problem to be solved by the present invention is not limited to the problems mentioned above, and other problems not mentioned here will be clearly understood by those skilled in the art from the following description.

The toilet seat attachment type foot washing device according to an embodiment of the present invention includes a body forming a frame, a washing water tank, a spray unit, a washing water supply unit, and a waste water discharge unit.

The main body is arranged in a state that wraps around the lower part of the existing toilet seat, and is formed in a U-shape having an open receiving space on one side of the toilet.

The washing water tank has an inner space where the user's feet are placed through an open upper surface and a waste water outlet formed on the lower surface, and has a structure that can be inserted into the open surface of the main body. That is, the washing water tank can be opened and closed by sliding from one open surface of the main body to the front and rear surfaces of the toilet seat.

The spray unit sprays a predetermined amount of washing water toward the inner space of the washing water tank.

The washing water supply part is connected to the spraying part, and supplies washing water to the spraying part.

The sewage discharge unit has a sewage inlet pipe connected to the sewage discharge port of the washing water tank, an odor blocking unit for blocking odor, and a sewage discharge pipe connected to the sewage discharge port of the bathroom floor. The sewage inlet pipe, the odor blocking part, and the sewage discharge pipe of the sewage discharge part may form the sewage discharge part as an assembly as separate parts, or may be integrally formed.

At this time, the sewage discharge port of the toilet floor may be a sewage discharge port for a sitting toilet that treats sewage from the sitting toilet or a sewage discharge port for a sewage treatment that treats sewage. Since there is only a discharge port, it is more preferable to discharge the sewage through the sewage discharge port of the sitting toilet.

The odor blocking unit has a function to block the bad odor coming from the sewage outlet on the floor of the toilet, and it can be implemented with a U-pipe or a dedicated valve.

On the other hand, the sewage discharge unit may be implemented by including it in a flange used when coupling the sewage pipe of the sitting toilet to the sewage discharge port of the toilet floor. For example, by deforming the eccentric flange, the sewage discharge part may be implemented to be included in the eccentric flange so as to discharge the sewage from the foot washing tank.

In general, the sewage outlet of the sitting toilet is located inside the sitting toilet, and the foot washing device of the present invention is located outside the sitting toilet. Therefore, when using an existing product on the market, it is necessary to make a hole in the bottom of the toilet seat or lift the entire toilet seat a little to enable piping.

To this end, the sewage discharge unit of the present invention may be configured to include a cradle. Here, the cradle raises the toilet seat to a predetermined height from the floor and serves to create a passage through which the sewage pipe (sewage inlet pipe of the sewage discharge part) can pass between the toilet seat and the toilet floor.

According to the present invention, the toilet seat attachment type foot washing device is installed in the space on both sides of the lower part of the existing toilet seat in a slidable structure to solve the space limitation, and convenience in consideration of receiving washing water and discharging waste water can be maximized.

To this end, the foot washing device of the present invention can wash the toes in the washing water tank, and discharge the sewage from the washing water tank to the sewage outlet of the bathroom floor without introducing odors.

Accordingly, the foot washing device allows the user to conveniently discharge sewage water without having to worry about the introduction of odors while cleaning between the toes, so that it is possible to wash the feet in a very comfortable environment.

In addition, the toilet seat attachment type foot washing device has a structure that can wash between the soles of the feet and toes evenly without bending the back and without using hands, so even people with limited mobility can wash their feet comfortably.

The toe spray nozzle 171 may be adjusted up and down, and may have a structure capable of spraying water while rotating.

Since the shape and size of the toes of each person using the foot washing device 100 according to the present invention are different, the toe spray nozzle 171 can be applied to an unspecified number of people according to the shape of the user's toes, so that the width of the washing plate 132 is different. It is possible to move the position by a predetermined length (installation interval) in the (and/or length) direction.

The position movement of the toe injection nozzle 171 for each user is stored in a memory device (not shown), and can be configured to be moved to a position stored for each user by a simple operation of the user input unit (160 in FIG. 5 ) later. For example, when two people A and B having different toe sizes and shapes use the foot washing device 100, A operates the user input unit (eg, presses button 1) to automatically activate the toe spray nozzle 171 This may correspond to an example in which the toe spray nozzle 171 can automatically move to a position that fits B's toe by moving to a position that fits A's toe, and B manipulates the user input unit (eg, presses button 2). .

13 is a diagram schematically illustrating an operation example of a heel washing unit in the device for washing a foot attached to a toilet seat according to an embodiment of the present invention.

The outer surface of the brush 182 may be made of a rough surface to effectively remove contaminants (eg, dead skin cells) between the toes. For the convenience of cleaning, it is preferable that the brush 182 has a structure detachable from the rotating member 181 .

When a command signal by which the user manipulates the user input unit 160 is transmitted to the control unit 200 , the driving unit 183 may rotate the rotating member 181 by the control unit 200 .

14 is a view schematically showing a modified example of the operation of the heel washing unit in the sitting toilet to which the foot washing device is attached according to an embodiment of the present invention.

Referring to FIG. 14 , the heel washing unit 180 may be disposed to be inclined at a predetermined angle along the shape of the heel, and may be configured in three pieces to surround the heel.

At this time, the heel washing unit 180 can be positioned horizontally and vertically through the position adjusting unit 184 . Other than that, the driving mechanism of the driving unit 183, the user input unit 160, and the control unit 200 is the same as that of FIG. 13 and thus is omitted.

On the other hand, as another configuration example of the heel washing unit 180, one rotation shaft may be configured to wash the heel and/or the heel while moving laterally in a direction perpendicular to the rotation shaft arrangement direction.

Since both the heel washing unit 180 and the washing plate (132 in Figs. 10 to 12) are located near the bottom (bottom) of the washing water tank (110 in Figs. 1 to 8), in order to reduce or eliminate mutual mechanical interference, It is preferable to reduce the size of the washing plate 111 and install the heel washing unit 180 in the remaining space to be spaced apart from the washing plate 111 by a predetermined distance.

As another embodiment, in addition to the heel washing unit 180, a forefoot washing unit (not shown) may be further installed at the front end of the foot washing device (100 in FIGS. 1 to 8). The heel washing unit has a function of washing and massaging the heel corresponding to the portion between the arch and the toes, and the specific structure is substantially the same as that of the heel washing unit described above.

Additionally, the foot washing device 100 according to the present invention may include a heating unit (not shown) for heating the washing water. The heating unit heats the washing water before spraying it using a hot water heater or an electric heater, so that the warm washing water is sprayed.

Hereinafter, the operation and control of the foot washing device 100 according to the present invention will be described. The operation of all electrical/electronic devices of the foot washing device 100 according to the present invention, including the above-described spray unit 150 , the washing liquid nozzle 155 , and the user input unit 160 in FIG. 5 , is performed by a control unit (not shown). controlled by

First, the injection pressure and injection operation control will be described in detail.

The foot washing apparatus 100 according to the present invention may be controlled such that each injection nozzle is sequentially injected in order to maintain the injection pressure of each injection nozzle at a predetermined level or more. For example, by operating in the order of the upward injection nozzle 154 - the side injection nozzle 153 - the toe injection nozzle 171, it is controlled to maintain the injection pressure above a certain level. Of course, a pressurization pump (not shown) that increases the injection pressure may be used as necessary, and if it is possible to maintain an appropriate injection pressure, it may be controlled to be simultaneously injected from two or more injection nozzles.

On the other hand, in order to increase the washing and massage effect, each nozzle can be controlled to spray with a spraying pressure that varies according to time.

Various combinations are possible for the spraying method of washing water and washing liquid. For example, when the washing water is sprayed by the spray unit 150, water and the cleaning liquid may be sprayed alternately from the same nozzle or according to a predetermined spray pattern, and the washing water mixed with water and the cleaning liquid may be sprayed, You can also make it spray only water. Alternatively, the cleaning liquid may be controlled to spray only from a dedicated nozzle (cleaning liquid nozzle) 155 .

The toe washing unit 170 ′ has one or more toe washing nozzles 171 ′ extending vertically upward and disposed between each user's toes, washing and massaging between the toes through rotation.

It is good to increase the washing power and massage effect by placing one or more protrusions on the outer peripheral surface of the washing member 172' surrounding the toe washing nozzle 171', and the body itself of the washing member 172' is hard, but the protrusions are soft. good night.

Hereinafter, a preferred embodiment of the automatic washing operation of the foot washing device 100 according to the present invention will be described.

The automatic washing function may consist of a step of step detection, a washing liquid spraying step, and a foot washing step. The step of detecting the step of placing the foot is a step of detecting that the foot is placed on the washing plate 132 . The cleaning liquid spraying step is a step in which the controller receives the foot position information value detected by the foot detection sensor (not shown), and drives the cleaning liquid nozzle 155 of the spraying unit 150 to spray the cleaning liquid. The foot washing step is a step of washing the feet by spraying water from the water spray nozzle unit when the first waiting time elapses after the washing liquid is sprayed.

Optionally, in the injection unit 150 to wash the inner space of the washing water tank 130 after a foot departure detection step in which the foot detection sensor detects that the foot has fallen from the washing plate 132 and the second waiting time has elapsed. It may be configured by adding an internal washing step of spraying washing water.

Here, the first and second waiting times mean a preset time in the corresponding process, and the corresponding time can be changed by the user.

The user may make various presets by using the user input unit ( 160 of FIG. 3 ). Basic values such as the injection pressure of the injection unit 150, the first standby time of the automatic cleaning function, the second standby time, and the cleaning liquid injection amount may be set.

The step of detecting the set foot is performed by the foot sensor.

The foot detection sensor may be implemented by installing a light receiving unit (not shown) and a light emitting unit (not shown) on the left and right inner walls of the washing water tank 130 , or by placing a pressure sensor on the bottom of the washing plate 132 .

The foot detection sensor transmits an information value that detects a position in which the foot approaches the washing plate 132 or a seated pressure value to the controller. The control unit is electrically connected to the foot detection sensor, compares the information value transmitted from the foot detection sensor with a preset reference value, and when the result matches the reference value, the control unit drives and controls the injection unit 150 .

In the step of washing the feet, the controller controls the injection unit 150 so that the inner receiving space of the washing water tank 130 is automatically washed for a preset time. Here, the preset time is a time calculated based on statistical values accumulated with various data, and the initial setting value may be different according to each function, and the setting value may be determined by the user. In order to enhance the effect of washing the feet, the injection method, injection pressure, and injection angle of the washing water and cleaning liquid may be automatically changed according to a user input or preset logic.

The internal washing step proceeds when the user removes the feet after washing the feet. When the washing plate 132 detects that the foot falls off, the injection unit 150 is stopped by the control unit, and the control unit controls the injection unit 150 to wash the inside of the washing water tank 130 using the automatic cleaning function. do.

For cleaning the inside of the foot sensing device 100, the control unit sprays the washing water toward the washing plate 132 for a preset time by adjusting the spray angle. The set time can be changed arbitrarily by the user. Alternatively, the cleaning time of the washing plate may be changed by detecting the degree of washing of the washing plate by using a contamination sensor (not shown) until an appropriate level of washing is achieved.

The washing water sprayed in the internal washing step may be a mixture of a washing liquid having a stronger washing power than the washing water at the time of washing the feet. To this end, the washing solution storage unit may be configured to store the washing solution for washing the washing plate separately from the washing solution for foot washing.

Above, the configuration of the present invention has been described in detail through several preferred embodiments. The present invention has a structure that can wash evenly between the soles of the feet and between the toes without bending the back and without using hands, so that even people with disabilities who have limited movement can wash their feet comfortably.

In addition, the foot washing device is equipped with a function of automatically washing the device after washing the feet, so that the conventional management problem can be solved. In this case, the foot washing device in which the feet have been washed may be configured to include an ultraviolet lamp (not shown) or a dry device (not shown) inside the cover of the body to eradicate bacteria or remove moisture.

It goes without saying that the present invention is not limited to the above-described embodiments and can be practiced with various modifications within the scope allowed by the technical idea of the present invention.
