Claims (1)

[Scope of utility model registration request] a semiconductor heater with positive characteristics as a heat source; a blower having a blower blade rotatably driven by a drive motor, which takes in air from the outside, supplies the air through the semiconductor heater into the drying chamber, and then discharges it to the outside as exhaust; and the exhaust air. a heat exchanger for exchanging heat between the exhaust gas and intake air; and a heat exchanger configured to detect the temperature of the exhaust gas, the drive motor being rotated at a low speed at the start of drying operation, and the drive motor being rotated when the exhaust gas reaches a predetermined temperature. A dryer equipped with a thermal switch that rotates at high speed.
