ンパー開閉装置。[Scope of claims for utility model registration] (1) A damper in a microwave oven with a heater,
In a damper opening/closing device for a microwave oven that is opened and closed by an actuator that utilizes the shape change of a shape memory alloy spring that has been subjected to shape memory treatment in the form of a tight coil, a heating wire with an insulating coating is placed around the shape memory alloy spring. A cooling fan is placed near the shape memory alloy spring, and a current is passed through the heat generating wire to change the shape of the shape memory alloy spring, thereby closing the damper and applying a current to the heat generating wire. In a microwave oven, the damper is opened by stopping the flow and cooling the shape memory alloy spring with the cooling fan to return the shape memory alloy spring to its original shape. Damper opening/closing device. (2) In the damper opening/closing device for a microwave oven according to claim 1, the actuator includes a coiled spring made of a shape memory alloy, a rod-shaped member passing through the coiled spring in the axial direction, and a rod-shaped member of the rod-shaped member. A first mounting member which is fitted with one end and has a fixed end of the coiled spring attached thereto, and a first mounting member which is slidably supported by the rod member and which has a driving end of the coiled spring attached thereto. A damper opening/closing device for a microwave oven, comprising: a second mounting member; and a pair of terminals attached to the first and second mounting members to connect the heating wires.
