Description

Micro-wave oven

technical field

The invention belongs to the technical field of kitchen utensils, and in particular relates to a microwave oven.

Background technique

A microwave oven is a device that cooks food using microwaves radiated from a magnetron into the cavity of the microwave oven. The principle of microwave heating is to use the high-frequency characteristics of microwaves to make polar molecules in food move at high speed in the electromagnetic alternating field generated by the microwave field to generate heat. Compared with other common stoves, microwave ovens have remarkable features such as high efficiency, high speed, high safety and high reliability.

Existing microwave ovens, its cavity assembly generally comprises back plate, top plate, U-shaped plate, front plate and waveguide assembly, is surrounded by back plate, top plate, U-shaped plate and front plate to form cavity, and U-shaped plate is respectively connected with top plate, The rear panel and front panel are riveted and fixed. In order to prevent the cavity from rusting, the sheet metal parts need to be painted. Usually, after the cavity is riveted, it is painted. Since there will be a certain dead angle of painting after riveting, it is very easy to cause the paint to not completely cover the inner wall of the cavity. After a certain period of use by the user, the parts not covered by paint are easily oxidized and rusted in humid air. In addition, at the waveguide opening of the cavity, an additional mica sheet needs to be installed to prevent the food juice from splashing into the waveguide opening, but this shielding method cannot be guaranteed to be completely effective. When flowing, food residues can still pass through the gap between the mica sheet and the cavity, and flow into the waveguide port. When the residual juice flowing into the waveguide port accumulates to a certain amount, ignition may occur, bringing safety hazards .

To sum up, the present invention utilizes the health, environmental protection and easy-to-clean characteristics of ceramics, and uses ceramics to make a cavity, and seals the outer layer of ceramics with a metal plate, that is, a side plate 14, to prevent wave leakage. When the user uses it, put food inside the ceramic cavity 12, close the oven door, start the microwave oven, the microwave emitted from the magnetron is guided by the waveguide plate 24, and enters the interior of the ceramic cavity 12 from the waveguide port 142 on the side plate 14 , when the microwave is inside the ceramic cavity 12, the microwave will not be reflected by the ceramic side wall, until it hits the metal side plate 14, it will be reflected, thereby repeatedly heating the food, due to the shielding of the ceramic cavity 12 side wall, the food will When the liquid juice is splashed, the liquid juice is blocked by the ceramic side wall and will not be sputtered into the waveguide port 142, thereby more effectively avoiding the occurrence of sparking phenomenon, and to a certain extent, prolonging the service life of the microwave oven and making it easier to use. Healthy and environmentally friendly, and easy to clean.
