A microwave oven door, and more particularly, an apparatus for shielding electromagnetic wave that compensates for the length of slots formed in an end of an oven door in order to improve the shielding ability capable of preventing the leakage of electromagnetic wave from the cavity. In the apparatus, a choke structure includes a choke base connected with an inner portion of the oven door, a choke inner side portion bent perpendicularly from the choke base and a choke top bent from the choke inner side portion to contact a front circumferential portion of an oven cavity. Slots are formed in the choke top and the choke inner side portion at a predetermined interval. Each slot is extended from a distal end of the choke top to a predetermined point of the choke inner side portion. The predetermined point is distanced the same as or smaller than the half of the width of the choke inner side portion from a joint between the choke top and the choke inner side portion.

A film for a light valve is made by phase separation of a mixture comprising a homogeneous polymeric solution and a liquid suspension of light-polarizing particles. Uniform liquid-suspension droplets in a polymeric matrix are formed by phase separation processing, e.g., by polymerization or solvent evaporation. Such simple, one-step processing results in cost reduction in display and window applications. Sealing problems of conventional light valves are alleviated.

A heating apparatus using an electromagnetic wave is disclosed, by which a capacity of a cavity is increased and by which cut-off performance of the electromagnetic wave and facilitation of door cleaning can be enhanced. The present invention includes a door provided to an open front side of a body to be opened/closed, a choke filter having a panel type choke part arranged by at least one or more rows along an edge of the door and a filter part having a plurality of slots wherein a prescribed choke part is provided to a most outer side, and a glass panel attached to an inner lateral side of the door and the choke filter.

A microwave oven has a casing which forms an appearance and has a front surface backwardly slanted and an adjusting portion formed at the slanted part; a cooking chamber formed inside the casing, for cooking food; and a door rotatably combined, i.e., hinged, at a side of the casing and slanted correspondingly the casing in order to opening and close the front surface of the cooking chamber.
摘要:
Microwave oven including a cavity for placing food therein, a magnetron for generating a microwave, a waveguide having at least two slots for guiding the microwave from the magnetron to an inside of the cavity, and a stirrer fan rotatably mounted on an inside of the cavity for varying an interfered state of the microwaves periodically, thereby heating the food more uniformly.
