Microwave oven is mainly composed of three parts, namely magnetron, oven cavity and power circuit. Magnetron is an independent electronic device, and its furnace cavity includes cavity, furnace door and field uniform structure. The power supply consists of magnetron power supply circuit, timer and power control circuit, safety protection circuit, cooling and lighting auxiliary circuit, etc. If you want to know more, look down: magnetron: its control magnetic field comes from the constant magnetic field of permanent magnet steel, so that the output power of the tube, that is, the anode current of the tube, will only be related to the applied anode voltage. Generally, the output power of magnetron is approximately proportional to the anode current. Furnace cavity: It is mainly used to place food, and a slow-rotating motor is installed at the bottom. It can drive the glass plate containing food in the cavity to rotate, so that it can constantly change its position and receive microwave radiation to achieve the purpose of uniform heating. Power supply: It plays an important role, but it is different from other household circuits. Inside the microwave oven, besides high voltage and high temperature, there is radiated microwave energy. In order to ensure the stability, reliability and durability of the microwave oven, and to ensure the safety of human body, a variety of safety protection measures are set in its circuit.
