On the other hand, since the air blower for deodorization was operated while the air blower was stopped, when either the air blower for hot air or the air blower for deodorization was operated, the operation of the other air blower was stopped. In addition, air can be efficiently blown at the time of deodorization.

Further, since the outside entrance is communicated with the inside exit by blowing air at the time of hot air, the outside air is prevented from being taken in from the inside entrance at the time of the warm air, and for example, a deodorizing catalyst provided at the inside entrance is provided. Since the air is blown without passing outside air, the efficiency of the air blow can be improved. On the other hand, since the external entrance and exit are not allowed to communicate with the internal exit due to the ventilation at the time of deodorization, the air inside the toilet seat is not blown from the internal exit to the outside of the toilet seat through the external entrance through the external entrance during deodorization. Air inside the toilet seat can be blown to the outside of the toilet seat from the internal outlet provided with the catalyst through the external inlet / outlet.
