Thus, in the ventilation operation mode, the air passage switching damper 24 is moved to the
ventilation position to drive the fan unit 21, whereby the steam and moisture in the bathroom
101 are exhausted.
[0059]
When the position of the air passage switching damper 24 is the diversion position shown by the
broken line in FIG. Since both 25b are formed, a part of the air sucked from the suction inlet
grille 40a of the front panel 4 is blown out from the outlet grille 40b into the bathroom 101
through the circulation air passage 25a.

dividing position to drive the fan unit 21 and the heater 26 is energized to circulate a part of the
air in the bathroom 101 to cause the bathroom 101 to rotate. Steam and moisture in the
bathroom 101 are exhausted while blowing hot air HA inside.
[0062]
In the cool air operation mode, the air passage switching damper 24 is moved to the diversion
position, and the heater 26 drives the fan unit 21 without power supply to circulate a part of the
air in the bathroom 101 to allow room temperature in the bathroom 101 The steam and
moisture in the bathroom 101 may be exhausted while blowing air according to the above.
