Rice cookers, also known as rice cookers and electric cookers. This is a cooker that converts electric energy into heat energy. It has many operating functions such as steaming, boiling, stewing and stewing. Easy to use, safe and reliable.
It can not only cook food, but also keep warm. It is clean and sanitary to use, pollution-free, time-saving and labor-saving, and it is one of the indispensable appliances for household modernization. During World War II, common rice cookers were divided into three types: automatic heat preservation type, timed heat preservation type and new microcomputer control type.
Temperature limiting device of rice cooker
Also known as magnetic steel. Equipped with permanent magnet ring and spring, it can be pressed at the center of the heating plate.
When cooking, press the cooking switch and drive the lever switch through the attraction of the magnetic steel to keep the power contact connected. When cooking, the temperature at the bottom of the pot keeps rising, and the attraction of the permanent magnet ring decreases with the increase of temperature. When the water in the inner pot evaporates and the bottom temperature of the pot reaches103 2℃, the attractive force of the magnetic ring is less than the elastic force of the spring on it, and the temperature limiter is pressed down by the spring to drive the lever switch to cut off.
