Microwave oven housing and microwave oven

Abstract

The invention relates to the field of household electrical appliances, and provides a microwave oven housing and a microwave oven. The microwave oven housing includes a housing body, the housing bodycomprises a top plate arranged horizontally, a first side plate and a second side plate, wherein the first side plate and the second side plate are arranged on the two opposite sides of the top plate,the first side plate is arranged close to a microwave oven transformer, the inner side of the first side plate is provided with an acoustic sound absorption structure or a multi-layer composite soundabsorption board, or the housing body is integrally formed by the multi-layer composite sound absorption board. According to the microwave oven housing and the microwave oven, vibration and 'buzzing'sound of the side plates can be lowered, thus the vibration noise of the microwave oven is improved, the sound quality is improved, and the user experience of the microwave oven is promoted.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a microwave oven shell and a microwave oven. Background technique [0002] As we all know, a microwave oven is an appliance that uses high-frequency electromagnetic waves generated by the oscillation of a magnetron installed in a machine room to heat and / or cook food placed in its cooking room. That is, during the cooking process, the magnetron installed in the machine room radiates high-frequency electromagnetic waves (ie, microwaves) into the cooking room. The microwave passes through the food to repeatedly change the molecular arrangement of the water contained in the food, which causes the water molecules to vibrate and generate frictional heat in the food to cook the food. [0003] Microwave ovens mainly have two noise sources. One is the vibration noise of the sheet metal side plate caused by the electromagnetic excitation of the transformer that supplies the magnetr...

AI Technical Summary

Problems solved by technology

[0004] In order to pursue the characteristics of compact appearance and large cooking chamber of microwave ovens, the transformer of most microwave ovens is very close to the side plate of the mechanical room, resulting in a large electromagnetic excitation force of the transformer on the side plate, which in turn leads to relatively strong vibration of the side plate, resulting in a large loud vibration noise

In addition, the side panels of existing microwave ovens are basically flat, and the side panels are not directly reinforced. The reinforcement treatment will directly affect the appearance of the product. In order not to affect the appearance of the microwave oven, the stiffness of the side panels is relatively weak if the side panels are kept flat. The vibration of the side plate will be stronger, and it will also produce a lot of vibration noise
