Door of microwave oven with structure for preventing microwave leakage

Abstract

The blockage structure is divided into multi blockages with short and long shape through adjusting the position of multi cutting grooves. Combining selection of two kinds of cutting groove width, the optimal structure has wide choke frequency band and small microwave leakage. The cutting groove is widened on the circumferential wall of the blockage structure to form rectangular hole. The rectangular hole is opened on circumferential wall of longer blockage to make the mechanic strength of circumferential wall basically same. The circumferential wall of each blockage with pin hole is made a lighter punch socket, and others are made deeper punch socket to enhance the mechanic strength. The multi jackcatches are set at the inner side face of door cover board to use the corresponding rectangular hole in the blockage structure for making position fixing. Strip hole is set at the edge fold on the outside wall of choke groove.

Description

Technical field [0001] The invention relates to a microwave oven door, in particular to a microwave oven door with the function of preventing microwaves from leaking out. Background technique [0002] A microwave oven that utilizes microwave heating to cook food is usually made into a box type. A cooking chamber with an open front and a closed equipment chamber are arranged in the box-type housing. The microwave generator assembly that generates microwaves and the electronic structural parts that control it are installed in the equipment room. The cooking chamber is used to place food to be heated and cooked. A door is installed at the opening at the front end of the cooking chamber. When the door is opened, food can be put in or taken out, and when it is closed, the microwave can be shielded and the cooking status of the food can be observed through the window formed by a plurality of micro-holes. However, if special measures are not taken in the gap between the door an...

Problems solved by technology

Also, in this technical scheme, the door screen, the sealing surface, the door frame and its blocking structure are formed by punching and bending metal sheets; the mechanical strength of each blocking is low, and it is easily deformed by external force; especially in the door frame and its blocking structure When the decorative board is installed on the structure, it is easy to cause some blockages to be deformed, and the leakage prevention performance will be deteriorated; in addition, it is difficult to form the outer wall around the choke groove and the outer peripheral wall
