Claims

[Scope of utility model registration request]

A heat circuit is connected to the power source via the first contact of a two-contact thermoswitch that detects the temperature inside the drying material storage drum and switches, and a second contact of the thermoswitch is connected to the power source. A delay relay connected via a contact, a normally closed contact of the delay relay inserted in series with the connection circuit between the first contact of the thermoswitch and the heater circuit, and parallel to the second contact of the thermoswitch. A normally open contact of the delay relay is connected to the delay relay, and a motor is connected to the power source and rotates the drum. one contact is turned off and a second contact is turned on, and
When the upper temperature drops to a second temperature lower than the first temperature, the second contact is turned off and the first contact is turned on, and the delay relay has a delay time from when it is energized until it operates each of its contacts. A dryer characterized in that the first contact of the thermoswitch is set to be slightly longer than the time it takes for the first contact to switch from off to on under normal conditions.
