[0002] A microwave oven is a household or industrial appliance that uses electromagnetic waves in the microwave band to heat objects (mainly polar molecules, such as water). A microwave oven consists of a power supply, a magnetron, a control circuit, and a cooking chamber. There is a rotatable stirrer near the entrance of the cooking chamber. Because the stirrer is a fan-shaped metal, it can reflect microwaves in all directions when it rotates, so it can evenly distribute microwave energy in the cooking chamber, thereby heating food. Its power range is generally 500-1000 watts, and the microwave roller is one of the essential accessories.
