Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hot water washing device for washing the buttocks in a Japanese-style toilet bowl.

[Background technology] Conventionally, when installing a hot water washing device on a Japanese-style toilet, a stand, etc. was used, and after making it into a Western-style seated toilet,
A warm water flushing device for Western-style toilets was installed. For this reason, modification of Japanese-style toilets is complicated, and the current situation is that Japanese-style toilets are not widely used.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the present invention is to provide a hot water washing device for a Japanese-style toilet bowl that can be used for hot water washing while leaving the Japanese-style toilet bowl as it is. There is something to do.

[Disclosure of invention] The present invention will be explained in detail below with reference to Examples.

As shown in FIG. 2, the main body of the hot water cleaning device A is formed by a footrest 1, a cleaning nozzle 2, and a hot water supply mechanism 3. The footrest 1 has a hollow rectangular plate shape, and has reinforcing ribs 27 for reinforcing the inside. A storage box 4 is provided integrally with the footrest 1 on the front side of the footrest 1, and a hot water supply mechanism 3 is housed inside the storage box 4. A hot water tank 5 is installed inside the storage box 4, and a heater 6 for heating the hot water to form hot water is installed inside the hot water tank 5. A pump 7 is set in a water tank (not shown) to supply water.
The pump 7 and the hot water tank 5 are communicated through a first water supply hose 8. A solenoid valve 9 is installed at the outlet of the hot water tank 5, and a cleaning hose 1 is connected from the solenoid valve 9.
1 is displayed consecutively. A solenoid valve 10 is disposed on the side of the solenoid valve 9, and a cleaning hose 12 is extended from the solenoid valve 10. Cleaning hose 11
A cleaning hose 12 is inserted into the footrest 1. The pump 7 and the solenoid valve 10 are in communication through a second water supply hose 13. A control board 14 of a control circuit for controlling the electromagnetic valves 9 and 10, the heater 6, and the pump 7 is mounted on the hot water tank 5. An operation panel section 15 is provided on the upper surface of the storage box 4. 16
1 is a power plug connected to a power outlet, and 17 is a transformer. As shown in FIGS. 2 and 3, a cylinder 18 is installed inside the rear part of the footrest 1 in the left-right direction, and a cleaning hose 11 is connected to the cylinder 18. The base of the cleaning nozzle 2 is a cylinder 18
The cleaning nozzle 2 is inserted into the cylinder 1 between the tip of the cylinder 18 and the base end of the cleaning nozzle 2.
A spring 19 is attached that biases the spring 19 in the direction of entering the inside 8. A flapper 21 that closes under its own weight is provided at the entrance 20 of the cleaning nozzle 2 provided on the footrest 1 so as to be openable and closable, and rebound prevention walls 22 are provided above and below the entrance 20. A cleaning nozzle 23 is provided in the entrance/exit 20, and the cleaning hose 12 is connected to the cleaning nozzle 23. A fitting recess 24 is provided on the lower surface of the portion of the footrest 1 where the entrance/exit 20 is located. The auxiliary footrest 25 is formed to have a substantially symmetrical appearance to the footrest 1, and includes a fitting recess 24 and a rebound prevention wall 22. On the floor surface 31 on both sides of the Japanese-style toilet bowl 26, as shown in FIG.
5 are disposed in symmetrical positions, and fitting recesses 24 are fitted and attached to the edges of the Japanese-style toilet bowl 26, respectively.

Next, the operation of the hot water cleaning device for a Japanese-style toilet bowl constructed as described above will be explained. One foot is placed on the footrest 1, straddling the Japanese-style toilet 26, and the other foot is placed on the auxiliary footrest 25 to defecate in the posture shown in FIG. 4. When the post-defecation cleaning switch is pressed, the solenoid valve 10 opens, the pump 7 rotates, water is sent to the cleaning nozzle 23 via the cleaning hose 12, and the cleaning nozzle 2 is cleaned. Next, when you press the cleaning switch, the solenoid valve 9 opens and the pump 7
rotates, and hot water is supplied from the hot water tank 5 to the cylinder 18 via the cleaning hose 11. The internal pressure of the cylinder 18 is increased by the hot water sent to the cylinder 18, the cleaning nozzle 2 is pushed out against the spring 19, the flapper 21 is opened, the cleaning nozzle 2 protrudes from the footrest 1, and the tip of the cleaning nozzle 2 is located at the center in the width direction of the Japanese-style toilet bowl 26 and corresponds to the buttocks, and in this state warm water is jetted from the tip of the cleaning nozzle 2 toward the anus to cleanse the buttocks. At this time, the splash prevention wall 22 prevents hot water for flushing from splashing out from the Japanese-style toilet bowl 26. When the washing switch is turned off after washing the buttocks, the supply of hot water is stopped, the hot water jetting from the washing nozzle 2 is stopped, and the washing nozzle 2 enters into the cylinder 18 by the force of the spring 19, and the washing nozzle 2 The user enters the platform 1 and the flapper 21 is closed.

FIG. 5 also shows another embodiment of the description. In this embodiment, the footrest 1 and the storage box 4 having the hot water supply mechanism 3 are formed separately, and the cleaning hose 1
1 and a cleaning hose. Furthermore, FIG. 6 shows an embodiment used in a toilet having a stepped portion 28 on the floor surface 31 corresponding to the rear of the Japanese-style toilet bowl 26 for both large and small purposes. In this case, an operation panel 29 is provided on the wall 30 of the toilet. In this way, the operation panel 29 will not be soiled by male urine or dirty water from cleaning.

[Effects of the invention] As mentioned above, the present invention places the footrest of the hot water washing device on the floor on one side of the Japanese-style toilet bowl, and creates an auxiliary footrest whose appearance is approximately symmetrical to the footrest. is placed on the floor on the other side of the Japanese-style toilet, and a cleaning nozzle that can protrude from above the upper surface of the rim of the Japanese-style toilet to approximately the center of the rear of the Japanese-style toilet is provided so that it can move in and out of the hot water cleaning device main body. Therefore, you can add hot water flushing functionality to an existing Japanese-style toilet by simply placing the footrest of the hot water cleaning device and the footrest auxiliary on the floor on both sides of the Japanese-style toilet. Moreover, by simply placing a footrest and a footrest auxiliary stand on an existing Japanese-style toilet, the hot water washing function for washing the buttocks can be achieved without any construction work on the Japanese-style toilet. It can be easily retrofitted, and since the appearance of the footrest of the warm water washing device itself and the footrest auxiliary stand placed on both sides of the Japanese-style toilet are approximately symmetrical, even if it is retrofitted, It does not cause any discomfort, and furthermore, the cleaning nozzle can be moved in and out, so the cleaning nozzle can be brought out only when cleaning the buttocks and retracted at other times, making it easier to use a Japanese-style toilet. In this case, there is no problem and there is no risk of dirt adhering to the cleaning nozzle.
