Claims

[Claim for Utility Model Registration] One end of the hot air circulation type high-frequency heating device that covers from outside the heating chamber a ventilation section consisting of a large number of small holes provided in a part of the inner wall of the heating chamber of the main body. A duct having an opening is provided with a pivot part that pivots a part of the damper that opens and closes the opening, and a disc-shaped or cylindrical cam is placed in the main body in the same direction as the damper opening direction. A pin is provided protruding near the outer periphery of the damper side surface of the cam, and a motor is provided inside the main body to rotate the cam in the above direction when operated from outside the main body. A motor switch is arranged so as to be pressed by the outer circumferential surface of the cam, which outputs an activation signal to the motor when pressed into the main body and outputs an operation stop signal to the motor when the pressure is released. In addition, a notch is formed on the outer peripheral surface of the cam to release the pressure on the motor switch and stop the motor operation when the damper is opened and closed, and a plate-like member is attached to the damper and the plate-like member is attached to the damper of the cam. A supporting member is installed to face and support the side surface, and a long hole is provided that opens and closes the damper by reciprocating the pin of the cam when it engages with the plate member and operates the motor. In the provided damper drive device, a circular arc is formed in the elongated hole so that when the damper is opened or closed, when the pressure on the motor switch is released and the motor operation is stopped, the damper remains in the open state or the closed state. A damper drive device characterized by having a section.
