Description

[0001] 【Technical field】 [0002] The invention relates to a household appliance for cooking, in particular to a microwave oven. [0003] 【Background technique】 [0004] A microwave oven is a common cooking appliance used to cook or heat food. It uses microwave energy to heat food placed in the microwave oven chamber. The traditional microwave oven is a magnetron microwave oven, including a power supply, a magnetron, a transformer, a high-voltage capacitor, a high-voltage diode, Control circuit, cooking cavity, oven door and other parts. The power supply provides high-voltage electricity to the magnetron, and the magnetron continuously generates microwaves under the excitation of the power supply, and then couples into the cooking cavity through the waveguide system. The principle is to use the magnetron in the microwave oven to emit a kind of microwave. After the microwave is absorbed by the food, the water molecules of the food will generate high-frequency oscillations, ...
