The temperature control elements of the Rice Cooker include a bimetal temperature control system and a magnetic material temperature control system. The former is not as safe and reliable as the latter. The electric rice cooker is divided into combined type and integral type according to the structure of the pot body; according to the pressure in the pot, it is divided into low pressure type (0.04MPa), medium pressure type (0.1MPa) and high pressure type (0.15~0.2MPa); The methods of heating food are divided into direct heating and indirect heating.
