Induction cooker is also called induction cooker. The principle of induction cooker is electromagnetic induction, that is, alternating current is used to generate an alternating magnetic field with changing direction through the coil, and eddy current will appear inside the conductor in the alternating magnetic field (please refer to Faraday's law of electromagnetic induction for reasons), which is caused by the eddy current electric field pushing the carriers in the conductor (the electrons in the pot are not iron atoms) to move; Joule thermal effect of eddy current heats the conductor, so as to realize heating.
According to the heating principle of induction cooker, a metal plate can be placed on the induction cooker to heat the ceramic casserole.

Induction cookers are divided into civil induction cookers and commercial induction cooker according to the places of use;
According to the purpose, it is divided into induction cooker, professional hot pot induction cooker, cafeteria insulation stove, kitchen soup stove and kitchen cooking stove;
According to the power, it is divided into induction cookers, low-power induction cookers (below 800W), ordinary-power induction cookers (1000W-2500W) and high-power induction cookers (3 kW-35 kW).
According to the way of use or installation, it is divided into embedded (sinking) induction cooker, desktop induction cooker and floor induction cooker.
In addition, some professional induction cookers are also named after the number, shape and configuration of burners.
Desktop induction cooker: it is divided into single-head and double-head, which has the advantages of convenient placement and strong mobility and is popular because of its low price;
Embedded induction cooker: put the whole induction cooker on the counter, and then dig a hole on the counter to make the stove top and counter top a plane. Experts in the industry believe that this installation method only seeks beauty and is unscientific. A large number of consumer groups regard the induction cooker as a hot pot. Embedded cooking is not convenient, and the embedded induction cooker can meet the needs of different pots and pans, so there is no special requirement for pots.
