Alternatively, it cleans a local part of a seated person jetted out of the bidet cleaning nozzle 5b. In this case, the washing is controlled so that the washing water is ejected from the poster washing nozzle 5a or the bidet washing nozzle 5b with a water amount corresponding to the rotation angle of the marking portion 8a of the operation section 8.

To stop the water supply and washing, the operation unit 8 is rotated so that the mark 8a is located at the "stop" position.
The closing is controlled so that water supply and washing can be stopped. In addition, even if the mark 8a of the operation unit 8 is not in the "stop" position, the user stops sitting and when the optical seating detection unit 4 detects that the user is not seated, a signal to that effect is output. The control is input to the control unit 7 and control for closing the valve unit 6 is performed.

Further, in a state where the seating is not detected by the optical seating detecting means 4 (a state where the signal of the non-seating state by the optical seating detecting means 4 is input to the control section 7), the mark on the operating section 8 is provided. Turn the part 8a to a position other than "stop"
Even if the mark 8a is positioned on the posterior open display 13a or the bidet open display 13b, the controller 7 controls the valve 6 while keeping it closed, and there is no mischief or the user's intention to use it. The cleaning water is prevented from being ejected from the nozzle 5 due to misuse of the nozzle.

If the mark 8a of the operation unit 8 is already in a position other than "stop", that is, in the position where the posterior open display unit 13a or the bidet open display unit 13b has not been detected, the above-described operation is performed. As described above, the valve section 6 is controlled to be closed. However, in a state where the mark section 8a is positioned on the posterior open display section 13a or the bidet open display section 13b, the user sits down and optically operates. Even if the seating is detected by the seating detecting means 4 and the seating detection signal is input to the control unit 7, the control unit 7 controls the valve unit 6 to remain closed, and thereafter, the detection of the seating is continued. At this time, the operating unit 8 is rotated to return the marking 8a to the "stop" position, and is rotated again to position the marking 8a on the posterior open display 13a or the bidet open display 13b. A signal is sent to the control section 7 to open the section 6, and the control section 7 causes the valve section 6 to open. The water is supplied into the local cleaning device 1 and the washing water (hot water) stored in the water storage tank 9 is ejected from the poster washing nozzle 5a or the bidet washing nozzle 5b. In this case, the washing is controlled so that the washing water is ejected from the posterior washing nozzle 5a or the bidet washing nozzle 5b with the amount of water according to the rotation angle of the mark 8a of the operation unit 8. is there.

Thus, in the present invention, when the mark 8a of the operation unit 8 is located at a position other than "stop", the washing water is prevented from being spouted from the nozzle 5 when the user sits down. After seating, the mark 8 of the operation unit 8
Open display section 13a for a bottom of a or open display section 13b for a bidet
Local washing with washing water can be performed by a simple operation of turning from the position to the "stop" position to the position of the buttocks open display portion 13a or bidet open display portion 13b.

In the above embodiment, an example in which the operation unit 8 is movable is described as an embodiment in which the operation unit 8 is movable. However, when the operation unit 8 is made movable, the operation unit 8 is moved by sliding. Also, in the case of the sliding operation unit 8, the operation unit 8 may be located at the position where the valve unit 6 is
When the operation unit 8 is located at the position where the valve unit 6 is opened, the amount of washing water ejected from the nozzle 1 can be adjusted according to the movement position of the operation unit 8. .

[0020]

As described above, according to the first aspect of the present invention, the movable operation section is located at the position where the valve section is opened, and the amount of washing water ejected from the nozzle is determined by the movement position of the operation section. Since it is configured to be adjustable, a single movable operation unit can be used for the operation means for opening and closing the valve unit and the water amount adjustment means for adjusting the amount of washing water ejected from the nozzle, simplifying the configuration. The number of parts can be reduced, the appearance can be improved, and the seating can be detected by the optical seating detecting means in a state where the operation unit is located at the position where the valve unit is closed. When the operation is continued, control is performed such that the valve section is opened by moving the valve section of the operation section from the closed position to the open position, and the optical seating is performed while the operation section is located at the position where the valve section is opened. Seating is not detected by the detection means Control is performed so that the valve unit is not opened when the operation is performed, and the detection of the seating is continued after the seating is detected by the optical seating detection unit while the operation unit is located at the position where the valve unit is opened. The control unit is configured to control the opening of the valve unit by returning the operation unit to the position where the valve unit closes and then moving the valve unit to the open position, so that the valve unit is in the open position. In the state (i.e., the state of water amount adjustment from the nozzle), even if the seating is detected by the optical seating detecting means, the control unit controls the valve so as not to open, so that the nozzle is suddenly turned on immediately after sitting. It is possible to prevent the washing water from spouting out of the valve, and even if it is seated in a state where the valve is in the open position (that is, in a state of adjusting the amount of water from the nozzle), the valve is not used. Return to closed and then open By opening the valve section, the amount of washing water that can be ejected from the nozzle according to the moving position can be spouted out. The washing water can be used to clean a local part of the human body.
