When the nozzle 32 extends and the inclined portion 32a of the nozzle 32 comes into contact with the inclined portion 31a of the cylinder 31, the water supply port 38 is connected to the cylinder chamber via the concave portion 31b formed on the inner periphery of the cylinder 31. 35, but even in the state of being housed in the cylinder 31, there is a gap between the cylinder 31 and the piston 33 formed at the rear end of the nozzle 32.
Slightly communicates with a water pipe 39 connected to the rear end of the water pipe.

Next, the operation when the cooling water is discharged will be described. In this embodiment, the user closes the toilet lid 33.
When opened , the cooling water in the hot water washing device 1 is discharged by the operation described below.

First, the user opens the toilet lid 33 from the closed state.
In this state, the sensors 52a and 52b detect it and send a signal to the control device C. The control device C receives this and opens the water supply electromagnetic valve 17, the first electromagnetic valve 29a, and the second electromagnetic valve 29b. When the water supply electromagnetic valve 17 is opened, the wash water is supplied to the water circuit in the hot water cleaning device 1, and the wash water that has passed through the water supply electromagnetic valve 17 is adjusted to a set pressure by the pressure regulating valve 18, and is sent to the water amount adjustment valve device 20. Is done. The orifice 2 is provided in the water amount adjusting means 20.
2. Five passages of the orifice 23, the first water flow control valve 25, the second water flow control valve 26 and the third water flow control valve 27 are provided in parallel, but when discharging the cooling water, the first water flow
The control valve 25 to the third water amount control valve 27 are closed.

Therefore, the washing water is supplied to the hot water tank 28 through the orifice 22 and the orifice 23. In this way, the hot water in the hot water tank 28 is pushed out to the water passage 16e, passes through the first solenoid valve 29a and the second solenoid valve 29b opened by the control device C, the anal cleaning nozzle device 30 and the bidet cleaning nozzle. Water is passed to the device 40. For example, hot water sent to the anal cleaning nozzle device 30 is:
Through the water pipe 39 is water from the gap between the cylinder 31 and the piston 33 in the cylinder chamber 35, the cooling water in the cylinder chamber 35 is discharged from the tip of the cylinder 31. The hot water supplied to the cylinder chamber 35 enters the water passage 36 from the water supply port 38 of the nozzle 32, and discharges the cooling water in the nozzle 32 from the jet port 37 at the tip of the nozzle. At this time, the amount of hot water supplied to the cylinder chamber 35 is such that the nozzle 32 does not extend, and
The ejection is performed in a state where the nozzle 32 is stored in the cylinder 31. In addition, the cooling water is similarly discharged from the bidet cleaning nozzle device 40. When the predetermined time has elapsed, the control device C closes the water supply electromagnetic valve 17, the first electromagnetic valve 29a, and the second electromagnetic valve 29b to stop the supply of the cleaning water, and also stops the discharge of the cooling water. Thus, the user
Toilet lid 3 anal cleaning nozzle unit and at the same time from a closed state to an open state 30, the cooling water that has accumulated in the bidet nozzle device 40 is discharged, the user discharge of cooling water and a nozzle
Since the cleaning condition can be checked visually,
A water washing device can be used. Also, the standby state is such that the cooling water is not drained whenever the user performs anal cleaning or bidet cleaning.

Next, the operation when performing anal cleaning will be described. When the user turns on the anal washing switch 5a provided on the upper surface of the main body 2, the control device C opens the water supply electromagnetic valve 17 to supply the washing water to the water circuit in the hot water washing device 1. At the same time, the control device C performs the first operation so that the water amount specified by the water amount
At least one of the water flow control valve 25, the second water flow control valve 26, and the third water flow control valve 27 is opened. For example, if the user has selected the weakest cleaning intensity, only the first water volume control valve 25 is opened to allow the cleaning water to flow through the orifice 25.
a. Thus, the washing water is supplied to the hot water tank 51 through the orifices 22, 23 and 25a. Then, water is supplied to the anal cleaning nozzle device 30 through the first electromagnetic valve 29a opened by the control device C. In the case of anal washing, unlike the case of discharging the cooling water, the amount of water supplied is large as much as the first water amount regulating valve 25 is opened, and the pressure of hot water supplied to the cylinder chamber 35 from the water pipe 39 is The piston 33 is pressed and the nozzle 3
2 extends. Thus, when the inclined portion 32a of the nozzle 32 comes into contact with the inclined portion 31a of the cylinder 31, the extension of the nozzle 32 stops, and the washing water supplied to the water passage 36 of the nozzle 32 is ejected from the ejection port 37 toward the human body. You. At this time, since the gap between the cylinder 31 and the nozzle 32 is sealed by the respective inclined portions 31a and 32a, the washing water does not leak from the tip of the cylinder 31. Next, when the end of the anal washing is input by the stop switch 5d or 6d, the control device C causes the water supply solenoid valve 17, the first
The water control valve 25 and the first solenoid valve 29a are closed to stop supplying the cleaning water to the anal cleaning nozzle device 30. Therefore,
The nozzle 32 is housed in the cylinder 31 by the urging force of the spring 34, and the anal cleaning ends.

The washing strength of the anal washing can be adjusted by combining the opening and closing of the first to third water amount adjusting valves 25 to 27 as shown in Table 1. The opening and closing of each solenoid valve during bidet cleaning is as shown in Table 2.

In this embodiment, the toilet lid 3 is changed from the closed state to the open state.
When the sensors 52a and 52b detect that
Although the cooling water was drained to the toilet , an infrared sensor was arranged near the entrance of the toilet or at a part of the main body 2 ,
The cooling water may be discharged at the same time as detecting that the user has entered the toilet. Or both
The cooling water may be discharged when it is detected.
