Common electric rice cookers are divided into three categories: heat preservation automatic type, timing heat preservation type and new microcomputer control type. Now it has become a daily household appliance, and the use of electric rice cookers has greatly reduced the time that families spend on cooking.

In the related technology, the heating technology of the electric rice cooker adopts IH electromagnetic induction heating, which converts the mains electricity into 20-30KHZ high-frequency electricity, and then makes the coil disk generate an alternating magnetic field, and the inner pot induces the alternating magnetic field to generate eddy current and hysteresis heating. Thereby realize uniform heating on inner pot body. This kind of IH electromagnetic induction heating greatly improves the disadvantages of uneven heating and low heating power of the previous thermal resistance heating plate.

However, IH electromagnetic induction uniform heating still cannot heat the rice evenly. According to the gelatinization characteristics of rice, starch granules will start to dissolve and gelatinize when cooking above 60°C, and produce stickiness. High, the rice grains quickly cohere into clumps and hinder the balanced convective distribution of heat and high-temperature air bubble flow. The non-stick coating of the inner pot is non-sticky. When air bubbles are generated, the cohesive rice grains are easily lifted up by the air bubbles and prevent the air bubbles from penetrating vertically upward. Unrolled, resulting in uneven distribution of air bubbles and uneven boiling of the rice.
