The washing water is supplied to h, and the washing water is ejected upward from the buttocks ejection port 53h to perform anal washing for a desired time.

After the anal cleaning, the cleaning stop switch operating section 22
Is operated, the electromagnetic valve 42 is closed and the electromagnetic valve 46 is opened by a command from the controller 85. When the electromagnetic valve 42 is closed, the supply of the cleaning water to the cleaning nozzle 53 is stopped.
The water pressure of the washing water decreases. Accordingly, air is supplied from the vacuum breaker 43 into the cylinder 51, and the gap (protrusion 51) between the flat portion 53m and the spring receiving portion 51e is promptly increased.
The water remaining in the cylinder 51 is discharged from the tube 47b) and the tube 47b, and the cleaning nozzle 53 is retracted by the elasticity of the return spring 54 to return to the initial position, and the piston 52 is moved to the rear cylinder 51B. Press against the inside. On the other hand, when the electromagnetic valve 46 is opened, the cleaning water is supplied to the nozzle cleaning chamber 51m through the tube 49a and the nozzle cleaning conduit 56, thereby cleaning the outer periphery of the nozzle 53. When the nozzle cleaning is performed for a desired time, the electromagnetic valve 46 is closed by a command from the control device 50.

When the user operates the washing start switch operating section 21 with the flow path switching and flow rate adjusting knob 25 at the bidet position, the electromagnetic valve 42 is opened by a command from the controller 85. When the electromagnetic valve 42 is opened, the washing water is supplied from the tube 44 into the rear cylinder 51B via the washing water supply port 55a, and the water pressure causes the piston 52 and the nozzle 53 to move forward against the return spring 54. 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 step portion 51c and stops. Piston 52
Stops, the nozzle 53 is not moved by the piston 52, but the washing water supplied into the rear cylinder 51B is flushed with the washing water outlet 51h → the washing water outlet 66 → the washing water inflow hole 71a → the washing water inflow groove 75a. And flows into the rear valve portion 75B, and is guided into the front cylinder 51A through the bidet outflow groove 75b → the bidet outflow hole 71b → the bidet outflow hole 65 → the bidet outflow inlet 51i, and the water pressure is applied. 2 to press the flange 53n of the nozzle 53.
As shown in 6, further extend and move to the bidet washing position,
At this position, the peripheral portion of the flange 53n comes into contact with the locking portion 51e to stop. By moving the nozzle 53, the bidet washing water outlet 51j → the bidet washing water outlet 64 →
Bid wash water inflow hole 71c → flows into front valve portion 75A via bidet wash water inflow groove 75c, and flows into flow adjustment groove 75d → wash water outflow hole 71d → flow control outlet 63 → communication flow path 62b.
→ Opening 62 for direction change → Reaching to pressure chamber 61 d of diaphragm 61 via communication channel 62 a, diaphragm 61 adheres to the side surface of cleaning nozzle 53, and connects bidet cleaning water from cleaning water inlet 61 a provided at the tip of diaphragm 61. Mouth 53
1 → Bidet cleaning passage 53g → Washing water is supplied to bidet outlet 53j, and flush water is spouted upward from bidet outlet 53j to perform anal cleaning for a desired time. When the washing stop switch operation unit 22 is operated, the nozzle 53 is washed and then returned to the initial state as in the case of the posterior washing. Even if the cleaning switch operating unit 21 is operated in a state where the flow path switching and flow rate adjusting knob 25 is at the middle position between the buttocks and the bidet, cleaning is performed because the micro switch 28 detects the stop state. Absent. In this state, if the cleaning stop switch operation unit 22 is pressed for a predetermined time or more, the electromagnetic valve 42 is opened and the nozzle 5
Performing only the advance of No. 3 makes it easy to wipe and clean the nozzle 53.

FIG. 27 is a schematic block diagram showing a normal water channel configuration and electric wiring, FIG. 28 is a schematic block diagram showing an emergency water channel configuration and electric wiring, and FIG. The figure which shows the state of the state which removed the lid from. In the figure, reference numeral 86 denotes a positive connection terminal to which an emergency battery 90 can be connected.
Denotes a negative connection terminal to which an emergency battery can be connected, which is a connection connector having a female end. Normally, the plus connection terminal 86 and the minus connection terminal 87 are short-circuited. Further, since the short-circuit connection is made via the backflow prevention diode 88, the current from the battery 80 does not flow between the connection terminals. Further, the positive connection terminal 86
A connection terminal to the battery 80 is provided in parallel with the negative connection terminal 87. The emergency battery 90 is provided with a connector 90a having a female end on the plus side and a connector 90b having a male end on the minus side. These connection connectors 90a, 90b are connected to connection terminals 86, 87, respectively.
Connected to. As shown in FIGS. 6 and 29, an opening 10f which can be opened and closed by a lid 91 is provided on the bottom surface of the lower case 10a located on the back side of the switch substrate 23 provided on the sleeve portion extending to the side of the device. As shown in FIG.
The connection terminals 86 and 87 can be taken out from the opening 10f from which the connection terminal 86 has been removed. In an emergency, the connection terminal 86,
The emergency battery 90 is connected to 87 and used. Normally, the connection terminals 86 and 87 are housed in the opening 10f in a short-circuit state, and the opening 10f is closed with a lid 91 made of an elastic material such as rubber as shown in FIG. Therefore, water does not normally enter through the opening 10f. The back side of the bottom surface of the lower case has a flat shape so that the emergency battery can be easily fixed with a double-sided tape or the like.
