AIR FLOW SYSTEM FOR A MICROWAVE OVEN

摘要

A microwave oven having a forced air flow system wherein the blower output is coupled directly to the power transformer of the high voltage power supply. The power transformer is positioned in an enclosure that houses the magnetron and may also encase other electrical components such as the high voltage capacitor, the high voltage rectifier, an oven light, and a fuse board. The blower is positioned outside the enclosure in a compartment housing the microwave oven controls, Air is drawn into the control compartment by the blower and then forced through a chute in the enclosure directly at the power transformer. By static pressure differential, air exhausts the enclosure through a plurality of predetermined paths. One path flows through the fins of the magnetron to an exhaust port. Another path flows through perforations into the cavity to remove moisture and rotate a microwave antenna.
