なるまで継続する。Then, the temperature of the mixed hot and cold water is detected by the mixed hot and cold water temperature sensor 28, and when the temperature is lower than the local cleaning set temperature value (124N),
Drain the water (125) and continue the same operation until the local cleaning set temperature value is reached.

The mixed hot and cold water is supplied to the local cleaning device 21 to clean the local area.

浄動作は完了する。If the local cleaning switch is turned off after sufficiently cleaning the local part (128), the valve drive device 25a is stopped and the flow rate adjusting valve 25 is closed (129). Therefore, the supply of the mixed hot water to the local hot water cleaning device 21 is stopped, and the cleaning operation is completed.

(133)。Next, when the user stands up from the local cleaning device 21, the seating detection means outputs an off output (130), and by the off output,
The control device D reads out the hot water filling conditions (for example, set temperature, integrated flow rate, etc.) in the bathtub flow path 18 stored in the step (122) (131), and opens the flow rate adjusting valve 27 by the valve drive device 27a. , The hot water filling operation for the mixed hot water bath 23 is continued (133).

In this embodiment, since the drainage passage 50 including the constant flow valve 51 is provided in the local cleaning device flow path 16, the temperature control valve B including the hot water flow rate control valve 12 and the water flow control valve 13 is provided. A large amount of hot water and water can be made to flow into the chamber to generate mixed hot and cold water, and a minute flow rate is desired by the temperature control valve B designed to supply a large flow of mixed hot and cold water to the bathtub 23, the shower head 24, etc. Even when it is supplied to the local cleaning device 21 of the above, it is possible to more accurately control the mixing ratio of the mixed hot water, that is, the appropriate temperature control, and the appropriate temperature of the cleaning water is supplied to the local cleaning device.
It is possible to inject and wash from 21 injection nozzles toward a local area, and it is possible to improve the user's feeling of use.
