Abstract: A microwave oven includes two doors which primarily and secondarily prevent a leakage of microwaves from a cooking cavity during a cooking operation. A first door is rotatably hinged to a front wall of a cabinet of the microwave oven, so as to open and close an opening of the cooking cavity and primarily prevent the leakage of the microwaves from the cooking cavity. A second door is rotatably mounted to the cabinet in front of the first door to cover and uncover the front of the first door. The second door thus secondarily intercepts the microwaves which have leaked from the cooking cavity through a gap between the first door and the cabinet. The microwave oven effectively prevents almost all leakage of the microwaves from the cooking cavity during the cooking operation.

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.

Abstract: A door for a microwave oven has a rectangular door frame, and a transparent door screen installed on a central area of the door frame.

Abstract: An output door mechanism for a microwave decomposition machine allows a rotating tank to be coupled to a fixed waveguide with both a vacuum and a microwave seal. The fixed waveguide delivers microwave power to the rotating tank in a decomposition machine. A moveable end cover joins the rotating tank to the fixed waveguide providing the rotating tank with a vacuum and microwave seal during the decomposition of material and discharge of the tank after the decomposition has been completed. The output door mechanism uses a rolling bearing to form a rolling seal, a sliding bearing to form a sliding seal, and a metallic bellows to form a flexible seal. A plunger compresses a spring to seal the end cover to the rotating tank. When the plunger no longer applies compressive force to the spring the end cover separates from the rotating tank to allow discharge of the decomposed material.
