Abstract
A seal for a cavity plate in a microwave oven is described herein. The seal includes a seal body having an outward sealing surface defined around a seal perimeter. The outward sealing surface is configured to seal against inward facing walls of a microwave oven. The seal body also includes an inward sealing surface spaced inward from the outward facing surface. The inward sealing surface is configured to seal against an outer edge of a cavity plate. The seal further includes a plurality of seal supports extending from the seal body on a cavity side of the seal body for maintaining cavity spacing between a bottom microwave oven surface and the seal body.
Claims20
A seal for a cavity plate in a microwave oven, the seal comprising:
- a seal body having an outward sealing surface defined around a seal perimeter, the outward sealing surface being configured to seal against inward facing walls of a microwave oven, and an inward sealing surface spaced inward from the outward facing surface and configured to seal against an outer edge of a cavity plate;
- and
- a plurality of seal supports extending from the seal body on a cavity side of the seal body for maintaining cavity spacing between a bottom microwave oven surface and the seal body,
- wherein the seal body and seal supports are of a single material with a first flexibility and further comprising for each of the seal supports, a reinforcement member having a second flexibility that is more rigid than the first flexibility, wherein the reinforcement member wraps around the respective seal support.
A seal for a cavity plate in a microwave oven, the seal comprising:
- a seal body having an outward sealing surface defined around a seal perimeter, the outward sealing surface being configured to seal against inward facing walls of a microwave oven, and an inward sealing surface spaced inward from the outward facing surface and configured to seal against an outer edge of a cavity plate, wherein the seal body defines a plate shape with an aperture therethrough for accommodating blades of a rotating stirrer;
- and
- a plurality of seal supports extending from the seal body on a cavity side of the seal body for maintaining cavity spacing between a bottom microwave oven surface and the seal body.
A microwave oven comprising:
- a cooking compartment defined by a plurality of inward facing side walls, an inward facing top wall, and an inward facing bottom wall;
- a microwave magnetron mounted within the microwave oven;
- a stirrer positioned on the bottom wall;
- and
- a cavity plate assembly comprising a plate body and a seal having:
- a seal body with an outward sealing surface defined around a seal perimeter, the outward sealing surface being configured to seal against inward facing walls of a microwave oven, and an inward sealing surface spaced inward from the outward facing surface and configured to seal against an outer edge of a cavity plate, and
- a plurality of seal supports extending from the seal body on a cavity side of the seal body for maintaining cavity spacing between a bottom microwave oven surface and the seal body,
- wherein the seal body and seal supports are of a single material with a first flexibility and further comprising for each of the seal supports, a reinforcement member having a second flexibility that is more rigid than the first flexibility,
- wherein the reinforcement member wraps around the respective seal support, and
- wherein the cavity plate seals off a cavity of the cooking compartment housing the stirrer from a main portion of the cooking compartment.
