Claims

[Scope of utility model registration request]

A drying chamber provided inside the outer box, a blower device installed to introduce air from outside the outer box into the drying chamber, and an air introduction path for introducing air from outside the outer box into the drying chamber. A main heater and an auxiliary heater each consisting of a semiconductor heater with a positive characteristic are provided to generate heat, and a main heater and an auxiliary heater are provided to operate by sensing the temperature of the air discharged outside the outer box, and the temperature thereof is below a predetermined value. When , only the main heater is energized, and when the temperature reaches a predetermined value or higher, the first temperature-sensitive switch and the auxiliary heater are energized together with the main heater, and the second temperature-sensitive switch has a predetermined value or more higher than the operating temperature. a second temperature-sensitive switch that cuts off power to the auxiliary heater when the auxiliary heater is turned off.
