BEST MODE FOR CARRYING OUT THE INVENTION The present invention comprises a heater and a blower for sending out warm air from the heater, and when the operation is started, the heater is energized after rotating the blower. .

At the start of the drying operation and the heating operation, the function of the protector cannot be kept up with due to a rapid temperature rise, and the thermal fuse will not be erroneously melted, so that the melting temperature of the thermal fuse can be lowered. The function of the thermal fuse at the time of abnormality can be improved.

Further, the rotation detecting sensor near the blower detects the rotation of the blower.

Since the heater is not energized when the blower is locked or the connector is disengaged, heat is not generated and it is safe, and the thermal fuse is not blown out, and repair is easy.

Further, a heater and a blower for sending out warm air from the heater are provided, and a heating path for releasing warm air is provided downstream of the heater via a hot air outlet for heating for heating a room. A drying passage for opening warm air through a drying hot air outlet for drying a local portion, and a damper for switching between the heating passage and the drying passage are provided.

Since the drying function and the heating function are performed by the same blower and heater, the number of parts is reduced, the toilet device can be downsized, and the installation place can be expanded.

Further, the filter for preventing dust clogging of the intake port on the upstream side of the blower is closed and effective during the heating operation, and opened and disabled during the drying operation.

In a drying operation for a short period of time, clogging of dust in the blower or heater can be ignored, so the amount of dry air can be reduced by opening and disabling the filter at the inlet on the upstream side of the blower. Therefore, the local area can be dried in a short time.

Embodiments of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals.
