Claims19
1-22. (canceled)
A combination oven assembly, comprising:
- a housing defining an interior cavity;
- a microwave cooking subassembly disposed and adjacent and through an opening in a top surface of said cavity and configured to direct microwave energy into said cavity;
- a turntable disposed at the bottom of said cavity;
- and
- a radiant heat cook subassembly disposed at the bottom and side exterior surfaces of said cavity and configured to heat the surfaces of the cavity from the exterior of said cavity, said subassembly having a radiating heating element and at least one heat distribution plate having a channel therein and being disposed adjacent said element, said plate forming at least a portion of an exterior surface of said interior cavity.
An assembly according to claim 1 further comprising first and second heat distribution plates disposed adjacent said heating element, said plates forming at least a portion of a surface of the interior cavity.
An assembly according to claim 1 further comprising three heat distribution plates disposed adjacent said heating element, each of said plates forming at least a portion of a surface of the interior cavity.
An assembly according to claim 1 wherein said plate comprises a channel, and said heating element is disposed within said channel.
An assembly according to claim 1 further comprising a rack removably disposed within said cavity, and wherein the turntable is disposed within a void of said rack.
A method for operating a combination oven having an interior cavity, comprising:
- selectively directing microwave energy into said cavity of said oven;
- selectively directing energy into the interior cavity with a heating element disposed outside of the interior cavity;
- and
- selectively operating a turntable disposed in the interior cavity.
