Abstract
A microwave oven (2) with a full glass door (12) for preventing microwave leakage from the cooking cavity (6) of the microwave oven (2) is provided. The front plate (8) of the cooking cavity (6) has a conductive material (10), such as a rubber with conductive filler. The inner glass surface (16) of the door (12) has a conductive coating that creates a ground loop with the conductive material (10) on the front plate (8) of the cooking cavity (6) to prevent microwave leakage from the cooking cavity (6).
Claims20
A microwave oven, comprising:
- a housing;
- a cooking cavity with a generally rectangular conductive material on the front plate of the cavity;
- and
- a door comprising:
- a frame;
- an outer glass layer coupled to the frame;
- an inner glass layer with a coating of conductive material at an inner surface thereof coupled to the frame;
- and
- wherein said conductive coating on said inner glass layer directly contacts said conductive material on the front plate of the cavity when the door is closed, creating a ground loop for the door, with the edges of said inner glass layer extending beyond the edges of said conductive material.
A door for a microwave oven, comprising:
- a frame;
- an outer glass layer coupled to the frame;
- an inner glass layer with a conductive coating at an inner surface thereof coupled to the frame;
- and
- wherein said conductive coating on said inner glass layer directly contacts a generally rectangular conducive material on the microwave oven when the door is closed, creating a ground loop for the door, with the edges of said inner glass layer extending beyond the edges of said conductive material.
A method for creating a ground loop for a microwave oven, which comprises a door, the door comprising a frame, an outer glass layer coupled to the frame, and an inner glass layer coupled to the frame, the method comprising:
- coupling a generally rectangular conductive material on the front plate of the cooking cavity of the microwave oven;
- and
- making a coating of conductive material on an inner surface of the inner glass layer of the door for the microwave oven to directly contact with the conductive material on the front plate of the cooking cavity so as to create a ground loop for the door when the door is closed, with the edges of said inner glass layer extending beyond the edges of said conductive material.
