KR960041899A - Microwave Leakage Shield - Google Patents

Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high frequency leakage shielding device of a microwave oven. It is formed so that it is strong in tolerance between door and oven front plate and can be attached to various kinds of microwave ovens as much as possible. The present invention is the first shielding plate which is integrally installed in the inner and outer viewing window of the door and one end is bent inward in multiple stages to shield the high-frequency energy in the X direction leaked out from the heating chamber; A second shielding plate which is separately formed at the center of the first shielding plate and whose one end is bent inward in multiple stages to shield high frequency energy in the X direction leaked out from the heating chamber; First and second choke seals formed by the first and second shielding plates and shielding high frequency energy in the Z direction leaking from the heating chamber to the outside; A first and second choke cover is installed in a straight line at one end of the first and second shield plates to block high frequency leakage of the first and second choke seals.

Claims (7)

A first shielding plate which is integrally installed in the inner and outer viewing windows of the door and whose one end is bent inwardly and shields the high frequency energy in the X direction leaked out from the heating chamber; A second shielding plate which is separately formed at the center of the first shielding plate and whose one end is bent inwardly and shields the high frequency energy in the X direction leaked out from the heating chamber; At least one choke seal which is divided by the first and second shielding plates and shields the high frequency energy in the Z direction leaked to the outside from the heating chamber; High frequency leakage shielding of the microwave oven, comprising first and second choke covers of arbitrary shape that are mounted in a straight line at one end of the first and second shield plates to block high frequency leakage of choke seals. Device. The microwave leakage shielding device of a microwave oven according to claim 1, wherein end portions of the first and second shielding plates have a certain period and are bent in two stages to be periodically configured. The microwave leakage shield of the microwave oven according to claim 1, wherein end portions of the first and second shielding plates have a certain period and are bent in one stage to be periodically configured. 2. The microwave leakage shield of claim 1, wherein the choke seal is two pieces. The microwave leakage shield of claim 1, wherein the choke cover of one of the first and second choke covers is square and the other choke cover is bent vertically. The microwave leakage shielding apparatus according to any one of claims 1 to 3, wherein the bent portions of the first and second shield plates act as chokes. 5. The high frequency leakage shielding apparatus according to claim 1 or 4, wherein the length of the choke seal is variable by separating and installing the second shielding plate. ※ Note: The disclosure is based on the initial application.
