Claims

[Scope of utility model registration request]

The temperature of the supplied air before heating into the drying chamber is detected by the first temperature sensing element, and the temperature of the discharged air from the drying chamber is detected by the second temperature sensing element.
The dry road is detected when the difference in temperature detected by the temperature sensing elements exceeds the reference temperature difference value, and a third temperature sensing element is provided to detect the air temperature outside the machine. A dryer further comprising a reference temperature difference value setting circuit that changes the reference temperature difference value in accordance with the temperature detected by the third temperature sensing element.
