Microwave absorption chamber for preventing microwave oven microwave leakage

Abstract

A microwave leakage preventing device, in particular for microwave oven, is a microwave absorption chamber equipped between oven port and oven chamber and used for absorbing leaked microwave. The invention improves the safety of microwave oven service. The microwave absorption chamber is a quadrangular chamber, a long opening is disposed at the side face close to the aperture between an oven chamber and an oven door, when the oven door is closed, and the leaked microwave passes through the aperture between the oven chamber and oven door and directly enters the microwave absorption chamber from the long opening to be absorbed. The long opening makes the absorption effect to leaked microwave not to be affected by the enlargement of the aperture between the oven chamber and oven door due to abrasion, so as to assure the safety of user for long time. The cross section of each edge of the microwave absorption chamber includes an inner layer and an outer layer, the outer layer is a metal layer, the inner layer is an absorption and transmission layer with meshes that are opened on each side faces and used for transmitting microwave, and microwave absorption absorbing material is coated on both the inner wall of the metal layer, the inner wall and outer wall of the absorption and transmission layer to form three microwave absorption layers, so as to reduce reflectivity of microwave, increase absorptivity to the leaked microwave, and more effectively achieve microwave leakage prevention purpose.

Description

1. Technical field [0001] The invention relates to a microwave leakage prevention device, especially for a microwave oven. A microwave absorption cavity is arranged between the oven door and the oven cavity to absorb leaked microwaves, thereby improving the safety of its use. 2. Background technology [0002] Due to the fast and convenient characteristics of microwave heating, microwave ovens have become an electrical appliance commonly used in modern home kitchens, and microwaves are very harmful to human health. Therefore, as a household appliance, microwave ovens are particularly important to prevent leakage. Microwave leakage refers to the leakage of microwaves from the source or heater (oven cavity) to the space outside the oven. The oven door is used to place food and observe the oven cavity, and also constitutes a front wall of the oven cavity. The leakage problem is the most prominent. [0003] In addition to the interlocking of the electrical appliances, the current...

AI Technical Summary

Problems solved by technology

[0003] In addition to the interlocking of the electrical appliances, the current method is to install a door seal in the gap, which is tightly attached between the furnace door and the furnace cavity to absorb microwaves. After the furnace door is worn out by multiple switches, the gap will increase, causing If there is no seal between the furnace door and the furnace cavity, the effect of the door seal will be reduced, and the amount of microwave leakage will increase, which exceeds the standard and will cause harm to users.

Even if it is a new microwave oven, due to individual differences in processing, there will be a certain gap between the oven door and the oven cavity, resulting in microwave leakage during work, but the user cannot find it in time, which will be extremely harmful in the long run
