ABSTRACT:
A microwave oven cavity air flow system having a grease shield adapted for receiving a nominal flow of air and efficiently using that flow to rotate the antenna and to remove moisture from the cavity. The air is first concentrated into a directive stream which impinges the vanes of the antenna rotating structure. Then, the air is directed into a dispersed flow towards the front of the grease shield wherein a first portion is directed down along the door and a second portion is directed back along the underside of the grease shield to directly transfer water vapor rising from the food to a rear exhaust. The grease shield has a channel for receiving an antenna mounting cradle.
