Even when the flush switch of the remote control is operated while the toilet seat support member 2 is in the lowered state, flushing of the toilet body 1 is performed. This cleaning is a manual cleaning performed by operating the switch by hand.
[0028]
In the this embodiment, in a state in which the seat support member 2 has been completed or or levitating the levitation it is adapted as the automatic washing of the is not executed. However, even at the time of the flying manual cleaning there as executable.
[0029]
When the lifted toilet seat support member 2 finishes descending, the automatic cleaning stop is not released yet for a predetermined time t, and only manual cleaning is possible during this t time. For this reason, even if the toilet seat 3e is touched to clean the toilet seat 3e or the cleaning operator is detected by the human body detection sensors 17 and 18, the automatic preliminary cleaning and the automatic flash cleaning are not executed. Therefore, it is prevented that water flows unnecessarily.
[0030]
Since the manual cleaning is possible during the time t, the water-soluble wiping cleaning paper that can be flowed to the toilet can be washed away. Of course, it is also possible to wash away the detergent and chemicals adhering to the bowl surface by flushing.
[0031]
In the above-described embodiment, the automatic cleaning stop and the manual cleaning possible time zone are provided for the time t after the completion of the downward movement detection. However, the automatic cleaning stop and the manual cleaning may be enabled when the lowering switch is operated. In this case, the end of the automatic cleaning stop and the manual cleaning possible time period may be a time point when t time has elapsed after the end of the lowering in FIG. 3B, or may be slightly earlier than that.
