Abstract
There is disclosed a microwave oven comprising a casing structure which defines a substantially triangular sectioned cavity and a hingedly supported door formed with a substantially triangular sectioned cavity. The cavity of the casing structure cooperates with the cavity of the hingedly supported door to define a complete heating chamber of substantially cubic body. The door is hinged at the top edge to the front edge of the top wall member of the casing structure.
Claims8
A microwave oven having a magnetron assembly which radiates microwaves into a heating chamber, which comprises a casing structure having an access opening leading into a cavity defined by said casing structure;
- a hingedly supported door hinged at the top thereof to the front edge of a top wall member of said casing structure for selectively opening and closing said access opening by the application of upwardly pulling and downwardly pushing forces to said door, respectively, said door being formed with a substantially outwardly concaved cavity which cooperates with said cavity of said casing structure to define said heating chamber when said door is in position to close said access opening;
- means for locking said door in the closed position;
- means for preventing said microwaves from leaking from around said hingedly supported door during closure of said door;
- and means for biasing said door towards an opened position.
