Operate the fans 17 and 31. When the amount of air supplied to the bathroom 3> the amount of exhaust air from the bathroom 3 is controlled by the operation of the timer 45 after a certain time has elapsed, the control unit 43 operates the heat exchanger 63 and the fan 65. At this time, fan 1
The air sucked from the blow-in port 15 by 7 is heated by the heat exchanger 63 in the heating suction unit 61, and a part of the air is blown out from the blow-out port 67 to the dressing room 1 by the fan 65 to heat the dressing room 1. .

When the amount of air supplied to the bathroom 3> the amount of exhaust air from the bathroom 3, the bathroom 3 tends to have a positive pressure, and air may enter the dressing room 1 from the bathroom 3 to cause dew condensation. Therefore, by raising the temperature in the dressing room 1, it is possible to prevent the occurrence of dew condensation in the dressing room 1.

Further, a calendar is attached to the controller of the bathroom heating / drying system so that the adjacent room can be heated only in winter. Alternatively, the bathroom heating / drying system is provided with a means for detecting the temperature in the adjacent room, and the adjacent room can be heated only when the temperature in the adjacent room is equal to or lower than a certain value. When the temperature in the adjacent room is low, such as in winter, when the moist air in the bathroom flows into the adjacent room, dew condensation is likely to occur. Therefore, the adjacent room is heated as described above to prevent dew condensation.
