When cleaning the toilet seat, first, the toilet seat is moved vertically to the rear of the toilet body with the toilet seat upright, and stored in the cleaning chamber, and the cleaning chamber is kept sealed. In this state, the upper surface of the toilet seat is cleaned by ejecting cleaning liquid from the plurality of nozzles of the cleaning device installed in the cleaning chamber toward the upper surface of the toilet seat, and after being cleaned, the plurality of nozzles are moved to the upper surface of the toilet seat. The upper surface of the toilet seat is dried by blowing air toward it.

However, since the toilet seat washing apparatus shown in Patent Document 1 is a system in which the toilet seat lid has a washing function, only the upper surface side of the toilet seat can be washed, and the water tightness between the toilet seat and the toilet seat lid is maintained. In addition to the problem that the wash water is likely to leak from the poor water tightness between the toilet seat and the toilet seat lid, the toilet seat cleaning device itself is a dedicated product that is attached to each toilet bowl, so one toilet seat cleaning device There is a problem that cannot be shared by an unspecified number of toilets.
In addition, the toilet seat cleaning device shown in Patent Document 2 is a method of moving the toilet seat to the rear of the toilet body and storing it in a built-in cleaning chamber, so it is necessary to install a water storage tank dedicated to the toilet seat cleaning device. In addition to being difficult to adopt in existing Western-style toilets, as well as the toilet seat cleaning device shown in Patent Document 1, the toilet seat cleaning device is a dedicated product that is attached to each toilet, so one toilet seat cleaning device cannot be shared by an unspecified number of toilets. There is a problem.
