When the user operates the cleaning start switch operation unit 21 with the flow path switching / flow rate adjusting knob 25 in the bidet position, the electromagnetic valve 42 is opened by a command from the controller 85. When the electromagnetic valve 42 is opened, cleaning water is supplied from the tube 44 into the rear cylinder 51B through the cleaning water supply port 55a, and the piston 52 and the nozzle 53 are advanced against the return spring 54 by the water pressure. For this reason, the nozzle 53 protrudes from the front end opening 51 w of the operation cylinder 51. When the piston 52 moves forward by the maximum stroke, the peripheral portion of the pressure receiving plate 52A comes into contact with the stepped portion 51c and stops. When the piston 52 is stopped, the nozzle 53 is not moved by the piston 52, but the washing water supplied into the rear cylinder 51B is washed water outlet 51h → wash water outlet 66 → wash water inlet 71a → wash water inlet groove 75a. Into the rear valve portion 75B, and is led into the front cylinder 51A through the bidet advance outlet groove 75b → the bidet advance outlet hole 71b → the bidet advance outlet hole 65 → the bidet advance outlet 51i. In order to press the flange 53n of the nozzle 53 with water pressure, as shown in FIG. 26, it further expands and moves to the bidet cleaning position. At this position, the peripheral portion of the flange 53n comes into contact with the locking portion 51e and stops. By the movement of the nozzle 53, the bidet washing water outlet 51j → the bidet washing water outlet 64 → the bidet washing water inflow hole 71c → the bidet washing water inflow groove 75c flows into the front valve portion 75A, and the flow rate adjusting groove 75d → washing. It reaches the pressure chamber 61d of the diaphragm 61 through the water outflow hole 71d → the flow rate adjusting outlet 63 → the communication flow path 62b → the direction changing opening 62 → the communication flow path 62a, and the diaphragm 61 comes into close contact with the side surface of the cleaning nozzle 53. The cleaning water is supplied from the cleaning water inlet 61a provided at the tip of the 61 to the bidet cleaning water communication port 53l → the bidet cleaning passage 53g → the bidet outlet 53j, and the cleaning water is spouted upward from the bidet outlet 53j to wash the anus For the desired time. When the cleaning stop switch operation unit 22 is operated, the nozzle 53 is cleaned and returned to the initial state as in the case of the buttocks cleaning. Even if the washing switch operation unit 21 is operated in a state where the flow path switching / flow rate adjusting knob 25 is in the middle position of the hip / bidet, since the stop state is detected by the micro switch 28, washing is performed. Absent. In this state, when the cleaning stop switch operation unit 22 is continuously pressed for a predetermined time or longer, the electromagnetic valve 42 is opened and only the nozzle 53 is advanced, so that the nozzle 53 can be easily wiped and cleaned.
