COOLING STRUCTURE FOR MICROWAVE OVEN

摘要

PURPOSE: A microwave oven cooling structure is provided to raise the cooling performance by concentrically ejecting the outer air to a magnetron and a transformer through an air guide duct. CONSTITUTION: A magnetron(1) and a transformer(5) are installed in a machine room. An air inlet(D) penetrates from the bottom(B) of the machine room to the outside. An air guide duct(13) is installed in the bottom(B) of the machine room for guiding the outer air to the magnetron(1) and the transformer(5), and has an air inspirator. The air inlet(D) is circularly shaped. The lower end of the air guide duct(13) communicates with the air inlet(D). The air guide duct(13) is circularly extended upward to form two outlets(13a) each facing to the magnetron(1) and the transformer(5) with proper intervals.
