As a result, the sewage scattered locally in the woman, such as the vaginal opening and the urethra, is washed away by clean washing water at the time of cleaning the anus, and local hygiene can be maintained. When the cleaning is completed, moving from the front to the rear at the speed set by the bidet cleaning controller 43, the closing valve 19 is automatically closed, and all the cleaning operations are completed.

As described above, in the present embodiment, the female anal cleaning switch 40 is provided in addition to the cleaning switch 33 and the automatic cleaning control circuit 39 is provided. By one-touch operation of the switch 40, the anal cleaning is started and the bidet cleaning is automatically performed. As a result, the sewage scattered over a wide area of the female part such as the vaginal opening at the time of anal cleaning is washed away again, and the female part after anal cleaning can be kept hygienic. Moreover, the operation becomes simpler.

Unlike the conventional example in which a single nozzle body is provided with both an anal cleaning nozzle and a bidet cleaning nozzle, the anal cleaning nozzle 23 and the bidet cleaning nozzle 24 are provided as dedicated nozzle bodies. In addition, the bidet washing nozzle 24 is not stained by splashing of sewage during the anal washing, so that the washing can be performed more cleanly.

An anal washing time adjuster 42 capable of adjusting the length of the anal washing time ta is provided, and a bidet washing speed adjuster 43 capable of adjusting the size of the bidet washing moving speed vw is provided. Since the preset circuit 41 for controlling the cleaning time and the bidet cleaning speed is provided, it is possible to set an arbitrary anal cleaning time and a bidet cleaning speed according to the user's preference.

FIG. 3 is a block diagram showing a sanitary washing apparatus according to another embodiment of the present invention. An automatic cleaning pattern control circuit 44 controls the moving speed and jet strength of the bidet cleaning nozzle during the final cleaning. Other configurations are the same as those of the embodiment shown in FIG. 1, and the same reference numerals are given and the detailed description is omitted.

In the above configuration, the operation of this embodiment will now be described.
The operation will be described. By selectively turning on the washing switch 33, normal anal washing and bidet washing can be performed in the same manner as in the embodiment shown in FIG. On the other hand, in the case of a female user, when the post-fecal female anal cleaning switch 40 is selected, as shown in the time chart of the operation state of the nozzle switching valve 27 in FIG. The valve 27 is controlled to supply cleaning water to the anal cleaning nozzle 23 side, and anal cleaning starts. The nozzle switching valve 27 is automatically controlled by the automatic cleaning control circuit 39 after the anal cleaning.
Is switched to the bidet cleaning nozzle 24 side, and bidet cleaning is started in FIG. In the bidet cleaning, as shown in the time chart of the cleaning operation state of the bidet nozzle in FIG. 5, the cleaning is started at the moving speed and the ejection intensity set by the automatic cleaning pattern control circuit 44. As a result, the sewage scattered in the female part such as the vaginal opening and the urethra during the anal cleaning is washed away by clean washing water, and the local hygiene can be maintained.
When the cleaning range set by the cleaning position control circuit 38 is completed with the cleaning pattern set by the automatic cleaning pattern control circuit 44, the closing valve 19 is automatically closed, and all the cleaning operations are completed.

As described above, in the present embodiment, the automatic cleaning control circuit 39 is provided and the automatic cleaning pattern control circuit 44 is provided. Cleaning from the urethra with sensitive skin sensation to the vicinity of the vagina is performed at a slow speed with a weak jet, and the vicinity of the anus is cleaned once at the time of anal cleaning, so that a strong jet can be cleaned at a high speed. Thereby, in addition to washing away the sewage scattered to the female local part such as the vaginal opening at the time of anal cleaning, the delicate female local part can be cleaned without irritation.
