ABSTRACT:
A microwave oven having griddle and convection cooking capabilities. A microwave oven cooking cavity has an aluminum bottom with a Calrod heating element coupled thereto. Convection heating is provided by routing air, introduced into the oven to cool electronics including the magnetron, between the cooking cavity and the outer housing of the oven. In this way, such air flow cools the outer housing of the oven. The air flows under the griddle and through a plenum adjacent to the heating element in order to further heat the air. The heated air is then directed into the cooking cavity to provide convection cooking. From the cavity, the air is exhausted from the oven through apertures disposed in the door adjacent to a choke seal.
