The pin 72 protrudes integrally at the center of the rear end surface of the nozzle 30, contacts the pressure receiving plate 29 </ b> A of the piston 29, and separates the piston 29 and the nozzle 30. This is because the cleaning water 31 flowing into the first cylinder 28A from the nozzle operation supply port 51 during bidet cleaning is supplied to the pressure receiving surface (back surface) side of the flange 71.
[0031]
The return spring 32 that biases the nozzle 30 in the return direction is a compression coil spring, and is elastically mounted between the spring receiving portion 40 and the flange 71.
[0032]
Next, the cleaning operation by the cleaning nozzle 21 having such a structure will be described.
FIG. 3 shows a state at the time of non-cleaning. In this state, the nozzle 30 is held at the initial position by the return spring 32 to press the piston 29 against the inner surface of the connector 43. At this time, the solenoid valves 23 and 24 and the switching valves V1 to V4 are closed.
[0033]
When the user operates the anal cleaning switch provided on the sleeve portion of the cleaning apparatus body 2 after the stool, the electromagnetic valve 23 and the switching valves V2 and V4 are opened. When the electromagnetic valve 23 is opened, the cleaning water 31 is supplied into the second cylinder 28B through the local cleaning supply flow path 33 and the connector 43, and the piston 29 is pressed by the water pressure. Therefore, the piston 29 and the nozzle 30 advance integrally against the return spring 32, and the front end portion of the nozzle 30 protrudes from the front end side opening 75 of the operation cylinder 28. When the piston 29 moves forward by the maximum stroke, the piston 29 comes into contact with the step portion 37 and stops. When the piston 29 moves forward and stops, the cleaning water 31 that has flowed into the second cylinder 28B passes through the first discharge port 52, the channel 35a, the channel 35c, and the channel 35e, and the nozzle cleaning water supply port. 50. On the other hand, since the switching valve V1 is OFF, it is not supplied to the nozzle operation supply port 51 of the first cylinder 28A through the flow path 35b. For this reason, the nozzle 30 also stops with the stop of the piston 29. This stop position is an anal cleaning position, and the cleaning water 31 supplied from the nozzle cleaning water supply port 50 to the anal cleaning passage 65 is jetted upward from the jet outlet 65a to perform anal cleaning for a desired time. .
[0034]
When the anal cleaning switch is turned OFF after the anal cleaning, the solenoid valve 23 and the switching valves V2 and V4 are closed and the solenoid valve 24 is opened. When the electromagnetic valve 23 is closed, the supply of the cleaning water 31 to the cleaning nozzle 21 is stopped, so that the water pressure of the cleaning water 31 decreases. Accordingly, the nozzle 30 is gradually retracted by the elastic force of the return spring 32 and returns to the initial position shown in FIG. 3, and the piston 29 is pressed against the inner surface of the connection tool 43. At this time, the washing water 31 remaining in the operation cylinder 28 is drained into the toilet from the front end side opening 75 of the operation cylinder 28 through the gap with the nozzle 30.
[0035]
On the other hand, when the solenoid valve 24 is opened, the cleaning water 31 is supplied to the nozzle cleaning chamber 62 through the nozzle cleaning supply flow path 34, thereby cleaning the outer periphery of the nozzle 30. In this nozzle cleaning, the amount of the cleaning water 31 used may be less than that in the local cleaning, and a part thereof is drained into the toilet through the drain passage 27. When the nozzle cleaning is performed for a desired time, the electromagnetic valve 24 is closed.
[0036]
When the user operates the bidet cleaning switch, the solenoid valve 23 and the switching valves V1, V3, and V4 are opened. When the solenoid valve 23 is opened, the cleaning water 31 supplied from the local cleaning supply flow path 33 flows into the second cylinder 28B through the connector 43, and the water pressure causes the piston 29 and the nozzle 30 to return. Move forward against 32. For this reason, the nozzle 30 protrudes from the front end side opening 75 of the operation cylinder 28. When the piston 29 advances the maximum stroke, the piston 29 comes into contact with the stepped portion 37 and stops. When the piston 29 is stopped, the nozzle 30 is not moved by the piston 29, but the cleaning water 31 supplied into the second cylinder 28B is the first discharge port 52—the flow path 35a—part of the flow path 35c— In order to press the flange 71 with the water pressure through the flow path 35b-nozzle operation supply port 51 and press the flange 71 with its water pressure, it is further extended as shown in FIG. At this position, the seal member 73 stops when it comes into contact with the locking portion 39. In this state, the rear opening 66b of the bidet cleaning passage 66 matches the nozzle cleaning water supply port 50, and the bidet cleaning is started. That is, when the nozzle 30 moves forward by the maximum stroke and stops at the bidet cleaning position, the cleaning water 31 introduced into the first cylinder 28A passes through the second discharge port 53-the flow path 35d-the flow path 35e, and the nozzle. Since it is supplied to the bidet cleaning passage 66 from the cleaning water supply port 50, the bidet cleaning is carried out for a desired time by jetting upward from the jet port 66a.
[0037]
When the bidet washing switch is turned off after bidet washing, the solenoid valve 23 and the switching valves V1, V3, V4 are closed and the supply of the washing water 31 is stopped. It can be returned to the initial position. Also at this time, the washing water remaining in the operation cylinder 28 is drained into the toilet from the front end side opening 75 of the operation cylinder 28 through the gap with the nozzle 30, and therefore remains in the operation cylinder 28. There is no such thing. Further, when the solenoid valve 24 is opened at the end of bidet cleaning, the cleaning water 31 is supplied to the nozzle cleaning chamber 62 through the nozzle cleaning supply channel 34 in the same manner as at the end of anal cleaning, thereby cleaning the nozzle 30. Do.
[0038]
When the anus and bidet washings are performed continuously, the solenoid valve 23 and the switching valves V2 and V4 are opened in the same manner as in the anus washing described above by operating the anus and bidet continuous washing switch. As described above, the gas is supplied to the second cylinder 28B through the local cleaning supply flow path 33, and the piston 29 and the nozzle 30 are advanced by the water pressure. Accordingly, the nozzle 30 moves to the anal cleaning position and performs anal cleaning for a desired time.
[0039]
When the anal cleaning is completed, the solenoid valve 23 and the switching valves V2 and V4 are automatically closed, and the solenoid valve 24 is automatically opened. When the electromagnetic valve 23 is closed, the supply of the cleaning water 31 to the second cylinder 28B is stopped, so that the piston 29 and the nozzle 30 are temporarily returned to the initial positions shown in FIG. On the other hand, when the electromagnetic valve 24 is opened, the cleaning water 31 is supplied to the connector 57 through the nozzle cleaning supply flow path 34, so that the nozzle 30 is cleaned for a desired time. When the nozzle cleaning is completed, it automatically switches to bidet cleaning, the solenoid valve 23 and the switching valves V1, V3, V4 are opened, and the solenoid valve 24 is closed. When the electromagnetic valve 23 is opened, the cleaning water 31 passes through the local cleaning supply flow path 33-the second cylinder 28B as described above, the flow path 35a-a part of the flow path 35c-the flow path 35b-the first cylinder 28A. -Flow path 35d-35e-Since it is supplied to the bidet cleaning passage 66, the bidet cleaning is performed for a desired time by advancing the nozzle 30 to the bidet cleaning position and ejecting it from the jet outlet 66a. When the bidet cleaning is completed, the solenoid valve 23 and the switching valves V1, V3, and V4 are automatically closed, and the piston 29 and the nozzle 30 are returned to the initial position shown in FIG. The nozzle 30 is cleaned for a desired time by opening the solenoid valve 24.
