PROBLEM TO BE SOLVED: To provide an efficient and economical bathroom drying system. SOLUTION: In a bathroom drying system, a temperature sensor 13 detecting the temperature of the air in a bathroom 1 is provided, and a ventilating fan 10 is constituted in such a manner that the number of revolution can be freely controlled. The temperature of the air inside the bathroom 1 is controlled to approach the set temperature by increasing the number of revolution of the ventilating fan 10 to increase the ventilation air volume in the case when the temperature of the air inside the bathroom 1 detected by the temperature sensor 13 is higher than the set value, and the temperature of the air inside the bathroom 1 is controlled to approach the set value by decreasing the number of revolution of the ventilating fan 10 to decrease the ventilation air volume by using a control circuit 12 in the case when the temperature of the air inside the bathroom 1 is lower than the set value.
