Abstract
A seal for use in a microwave oven having a griddle feature. An aluminum plate having a Calrod heating element coupled thereto provides a griddle and is disposed in an aperture in the stainless steel floor of the microwave oven. The griddle has a lip extending over a peripheral portion of the floor adjacent to the aperture therein. A U-shaped clamp comprising a bracket and a fastener couples the griddle to the peripheral portion of the floor. More particularly, the fastener draws the griddle downwardly to engage the lip down on the peripheral portion of the floor. With this arrangement, a continuous metal-to-metal contact is provided between the lip of the griddle and the microwave oven floor to prevent leakage of microwave energy. Moreover, the griddle can expand and contract free of restriction by the steel floor to prevent buckling. A gasket may be disposed between the lip of the griddle and the peripheral portion of the floor to provide a liquid seal.
