Problems solved by technology
Due to the large power frequency and multiplier components of the transformer magnetic field, it is easy to excite the vibration noise of the surrounding shell components, and it is difficult to completely avoid the resonance frequency of the shell components
Therefore, the dissipated magnetic flux leakage energy is converted into vibration and noise energy, which makes the microwave oven generate greater vibration and noise

The invention discloses a shell assembly for a microwave oven and the microwave oven. The shell assembly for the microwave oven comprises a bottom plate and a side plate, wherein the side plate is arranged on the bottom plate; the side plate is an integrally molded part and comprises a main body part and a baffle plate assembly; the baffle plate assembly extends outside from the edge of the main body part; partial surface of the main body part is opposite to a transformer of the microwave oven; and the baffle plate assembly is located between the transformer and the main body part. According to the shell assembly for the microwave oven disclosed by the embodiment of the invention, by virtue of the integrally molded side plate, the baffle plate assembly extends outside from the edge of the main body part, and is located between the transformer and the main body part, so that leakage flux generated by the transformer can be isolated by the baffle plate assembly; vibration generated by the main body part due to electromagnetic excitation can be reduced; the noise can be reduced; parts of the microwave oven can also be reduced; the production cost is reduced; and the assembly efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a shell assembly for a microwave oven and the microwave oven. Background technique [0002] Microwave oven has been widely used in people's daily life as a kind of convenient and fast multifunctional cooking and heating appliance. The working principle of the microwave oven is: the input power is boosted by a transformer and rectified by a diode capacitor to generate high voltage for the magnetron, and the magnetron generates microwaves and transmits them to the cooking chamber to heat the food. As an electrical device for voltage adjustment and energy conversion, the main components of the transformer are primary coil, secondary coil and iron core (magnetic core). The commercial AC current enters the transformer, and the alternating magnetic field of the input AC frequency and its multiplied frequency is generated in the iron core through the electromagnetic induct...
