Microwave leakage prevention device for microwave oven

Abstract

The invention relates to a microwave leakage prevention device for a microwave oven. The microwave oven comprises a high-frequency microwave generator, an oven body having a cooking room and an oven door for opening and closing an entrance of the cooking room. A front plate used for limiting the appearance of the entrance is arranged at the entrance of the cooking room of the oven body. The oven door comprises a contact part which is arranged to be opposite to a corresponding part of the front plate of the oven body and can fit with the corresponding part of the front plate when the oven door is closed. The invention is characterized in that the microwave leakage prevention device comprises a boss-type microwave obstruction structure which extends along the vertical direction of a binding face of the contact part and the corresponding part of the front plate of the oven body, has the consistent appearance with the entrance of the cooking room, has a height high enough to block or reflect microwave leaking from a gap between the oven door and the oven body and is prepared from a material that microwave cannot pass through. According to the invention, the amount of leaked microwave is greatly reduced, and use security of human body is effectively guaranteed.

Description

technical field [0001] The invention relates to a device for preventing microwave leakage of a microwave oven, thereby increasing the use reliability of the microwave oven. Background technique [0002] Microwave ovens use a high-frequency microwave generator to generate high-frequency microwaves to cook food. A general microwave oven includes: a high-frequency microwave generator, a furnace body with a cooking chamber, and a furnace door that opens and closes the entrance of the cooking chamber. The high-frequency microwaves supplied to the cooking chamber for cooking are harmful to the human body, so the oven door and the oven body of the microwave oven should be designed to prevent this from happening. There are various technologies for preventing microwave leakage, and the most common is the blocking door structure arranged on the furnace door. [0003] In this blocking door structure, a recessed portion of a given shape is formed at a predetermined position on the ove...

AI Technical Summary

Problems solved by technology

[0004] For the furnace door of this structure, the steps of bending the shielding plate and the additional plate and then welding them together make the production process complicated

The most important thing is that it is impossible to achieve a true seal between the contact portion of the shielding plate and the front plate of the furnace body, and a large amount of high-frequency microwaves will still leak out through the gap between the contact portion of the shielding plate and the front plate of the furnace body. At this time, although there is a blocking door structure to block the leaked microwaves, there will still be a small amount of microwaves that will leak out of the furnace body through the blocking door structure. When people approach the furnace body, it will still cause harm to the human body.
