The opening is adjusted while communicating with the selected side. For example, when the posterior washing is selected, the washing water flows into the nozzle cylinder pipe 13 from the washing port 5b, and the water pressure acts on the piston portion 23a of the posterior washing nozzle 3 and resists the urging force of the spring 25. The buttocks washing nozzle 3 is pushed toward the projecting position. In the meantime, a part of the washing water flows into the nozzle shaft 23 and flows out a small amount from the ejection part 3a at the tip,

Sometimes, a suitable temperature of hot water is spouted toward the local area.

In the above description, an example has been described in which the cleaning nozzle 3 is cleaned (pre-cleaning) by switching the flow rate control switching valve 5 with a slight delay after opening the electromagnetic on-off valve 9. In such a case, the flow rate control switching valve 5 is switched to the minimum flow rate (a flow rate equal to or less than one of a certain flow level of 5 or 6 levels), the electromagnetic switching valve 9 is opened, and then the flow rate is changed. The control switching valve 5 is switched to the opening of the predetermined flow rate level.

When the posterior washing nozzle 3 is protruded to its protruding position as shown in FIG.
Seal ring 26 provided on the nozzle cylinder pipe 13
The nozzle water is pressed against the step 13b at the tip of the nozzle to seal the inside of the nozzle cylinder pipe 13 and stop the volume expansion.
a, and is urged vigorously toward the local area from the ejection hole, whereby the washing is surely performed.

When the cleaning for a predetermined time is completed, the flow control switching valve 5 is switched to the original standby state, and the electromagnetic on-off valve 9 is closed with a slightly delayed timing. As a result, the buttocks washing nozzle 3 at the projecting position returns to the standby position by the urging force of the spring 25, and washing water flows through the washing water supply passage 30 and discharge holes 31a, 3
Cleaning water is supplied toward the outer surface of the ejection portion 3a of the posterior washing nozzle 3 that has returned to the standby position from 1b, and cleaning is performed.

Alternatively, after the cleaning is completed, the electromagnetic on / off valve 9 is closed, the flow rate control switching valve 5 is switched to the original state with a slight delay, and then the electromagnetic on / off valve 9 is opened for an appropriate time to clean the cleaning nozzle 3 ( Post-cleaning) may be performed. In some cases, cleaning is not performed thereafter.

It is needless to say that the bidet cleaning nozzle 4 operates in the same manner even when the bidet cleaning is selected and has the same function and effect.

As described above, according to the present embodiment, the flow rate control switching valve 5 is provided with the nozzle cleaning port 5d, and the cleaning water supplied from the nozzle cleaning port 5d is used to push the buttocks cleaning nozzle 3
Is supplied to the outer surfaces of the jetting portions 3a and 4a of the bidet cleaning nozzle 4, so that even if dirt or the like adheres to the jetting portions 3a and 4a and the outer surface is contaminated, the dirt can be cleaned. In addition, proper cleaning action and sanitary condition can be ensured.

A flow control switching valve 5 is provided at the base end of a pair of nozzle cylinder pipes 13 and 14 for guiding the cleaning nozzles 3 and 4 out and out.
Since the cleaning water supply passage 30 for supplying the cleaning water flowing out from the nozzle cleaning port 5d toward the outer surfaces of the ejection parts 3a and 4a of the cleaning nozzles 3 and 4 is disposed in the space between the nozzles 3 and 14. , And can be made compact.
