DEVICE FOR VENTILATING COOKING CHAMBER OF MICROWAVE OVEN

摘要

PURPOSE: A ventilator of a cooking chamber in a microwave oven is provided to quickly heat food in a cooking through a heater. CONSTITUTION: An inlet(36) to suck air into a cooking chamber(32) and an outlet(36') to ventilate air are opened and closed simultaneously. In using a heater, the inlet and the outlet are simultaneously closed. In using microwaves, the inlet and the outlet are simultaneously opened. Thereby, the air flow through the cooking chamber is performed smoothly. A suction damper(50) to open and close the inlet is driven by a damper motor(52). A vent damper(60) to open and close the outlet is driven by receiving the driving force of the damper motor. A driving lever(55) is installed in an output shaft(53) of the damper motor. An interlocking lever(57) is driven by the driving lever. Thereby, the vent damper is opened and closed.
