Abstract
A microwave oven feed system having the output probe of the magnetron inserted directly into the microwave enclosure. A rotating feed structure positioned within the enclosure couples the microwave energy from the probe into a directive radiation pattern towards the food. The feed structure may be located in a well extending from the enclosure and separated from the processing cavity by a layer of microwave transparent material, the functions of the layer being to provide thermal isolation and to provide a protective covering for the feed structure. A microwave choke around the periphery of the well prevents leakage of microwave energy from the enclosure. The choke may be elevated from the floor of the cavity to prevent food drippings and spilled soups from running into the feed structure well.
