MICROWAVE OVEN WITH VARIABLE CAVITY GEOMETRY OF COOKING CHAMBER

摘要

Microwave oven system with enhanced microwave radiation uniformity in a cooking chamber. The microwave oven includes a stirrer installed outside the cooking chamber and operable to vary a cavity volume or a cavity shape of the cooking chamber while the stirrer rotates for more uniform food cooking. The stirrer may be disk-shaped and can simultaneously rotate and move vertically to change the cavity volume of the cooking chamber during operation. Alternatively, the stirrer may be installed in an inclined angle and can change the cavity shape of the cooking chamber when rotating.
