TURN TABLE MOTOR COOLING STRUCTURE OF MICROWAVE OVEN FOR FORMING AIR INLET HOLE AT SEPARATING WALL TO COMMUNICATE LOWER SPACE FORMED UNDER ELECTRIC PART-MOUNTING CHAMBER AND CAVITY

摘要

PURPOSE: A turn table motor cooling structure of a microwave oven is provided to prevent the temperature of a turn table motor from rising by flowing the air supplied by a cooling fan into a lower space formed under a cavity and contacting the air with the turn table motor. CONSTITUTION: A turn table motor cooling structure of a microwave oven is composed of a cooking chamber(60) having a turn table(66) formed at the lower end and rotated with putting foods on the upside; an electric part-mounting chamber(70) formed at the side of the cooking chamber and placed with various electric parts like a cooling fan(76) for forcibly sucking in and blowing the external air; and a turn table motor(M) disposed in a lower space(80) at the lower side of the cooking chamber to supply rotary power to the turn table. The air fed by the cooling fan of the electric part-mounting chamber flows into the lower space mounted with the turn table motor by communicating the lower space and the electric part-mounting chamber.
