Microwave ovens/microwaves, as the name suggests, use microwaves to cook rice. A microwave oven is a modern cooking hob that uses microwaves to heat food. Microwave is an electromagnetic wave. The microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking chamber. The power supply supplies approximately 4,000 volts of high voltage to the magnetron, and the magnetron continuously generates microwaves under excitation of the power source and is coupled to the cooking chamber through the waveguide system. Near the inlet of the cooking chamber, there is a rotatable agitator. Because the agitator is a fan-shaped metal, it has a reflection of the microwave in all directions after being rotated, so that the microwave energy can be evenly distributed in the cooking chamber. The power range of a microwave oven is generally 500 to 1000 watts.
