Abstract
A microwave oven is provided herein having a cooking cavity, a dividing shelf for dividing the cooking cavity into at least two sub-cavities, and a door movable between an open and closed position for selectively providing and preventing access to the sub-cavities respectively. The door is provided with a choke frame configured to communicate with the dividing shelf in the closed position so as to attenuate microwave transmission between the sub-cavities.
Claims17
A microwave oven comprising:
- a cooking cavity , a dividing shelf for divided the cooking cavity into first and second sub-cavities, a door movable between a first position for simultaneous access to the first and second sub-cavities and a second position for preventing simultaneous access to the first and second sub-cavities, and a choke frame on the door, wherein the choke frame is in communication with the dividing shelf when the door is in the second position to attenuate microwave transmission between the first and second sub-cavities.
A microwave oven comprising:
- a cooking cavity and a dividing shelf for dividing the cooking cavity into first and second sub-cavities, wherein the dividing shelf comprises a gasket disposed around all sides thereof to attenuate the transmission of microwaves between the sub-cavities, an upper dielectric layer, and a lower structural layer that is not transparent to microwaves and spaced from the upper dielectric layer with thermal insulation material between the upper dielectric layer and lower structural layer.
