Ferrite heating apparatus

摘要

A microwave heating appliance having a metallic member supporting a body comprising ferrite bonded to an outer surface of the metallic member with a grooved inner surface of the metallic member contacting a food body to be heated by thermal energy generated from microwave energy absorbed by the ferrite body and transferred through the metallic member to the food body. An additional metallic member forms a container for the food body, and adjacent peripheral areas of the two metallic members provide substantial microwave sealing between the two metallic members thereby substantially shielding the food body from the microwave energy when the appliance is placed in a microwave oven. Upper and lower surfaces of the interior of the appliance contain grooves to form corrugated surfaces which contact the food body and which permit juices produced by heating the food body to flow away from regions of contact between the corrugated surfaces and the food body.
