ABSTRACT:
A door assembly for a microwave oven that includes a deformable thin stainless steel plate which is sandwiched between a compression frame and a choke structure. To open the door, the plate is moved upward and away from the compression plate and the choke. In the closed position, the compression plate is pressed back under tension against the choke by the compression frame to prevent leakage of microwave energy. Tension force may be applied, for example, by the use of angled flanges or pneumatic door clamps. The door assembly is readily adaptable to both batch type and continuous feed processing. Because of the single moving lightweight plate, the assembly achieves a low cycle time access opening, eliminates the need for heavy and cumbersome structures which in turn also reduces the potential for injury.
