PURPOSE: To execute a drying mode and a ventilation mode by changing the wind quantity at the part of a centrifugal blower and to dispense with a conventional electromotive damper by mounting a hot air generating centrifugal blower part and a ventilating centrifugal blower part on the rotary shaft of one motor and changing over the rotary direction of the motor. CONSTITUTION: In a drying mode, a motor 3a is rotated in a rotary direction increasing the wind quantity of a hot air sirocco fan 4a and air is guided to a heater chamber through a hot air generating fan cover 8a to be heated by the heat of a heater and discharged as hot air from a hot air blowoff port 12a. At the same time, a ventilating sirocco fan 5a is rotated in a direction small in wind quantity and a small amt. of air is discharged to the outside from a ventilating exhaust port 10a through a duct. In a ventilating mode, the motor 3a is reversely rotated to increase the wind quantity of the ventilating fan 5a and air in a bathroom is sucked only by the ventilating fan 5a to be discharged to the outside through the ventilation exhaust port 10a. |
