What brand of induction cooker is good?

Midea, Supor and Jiuyang brand induction cookers are all better.

The induction cooker adopts the principle of magnetic field induction eddy current heating. The induction cooker uses the current flowing through the coil to generate a magnetic field. When the magnetic force in the magnetic field passes through the bottom of the iron-containing pot, the magnetic stripe at the bottom of the induction cooker will produce countless tiny eddy currents when forming a closed loop, which will make the pot itself heat at high speed, and then the iron molecules in the iron pot move at high speed to generate heat, thus heating the food in the pot.

Electromagnetic waves generated when the induction cooker works are completely absorbed by the shielding layer at the bottom of the coil and the iron pan on the top plate.

Electromagnetic induction cookers are used to heat food. The surface of the induction cooker is a heat-resistant ceramic plate. Alternating current generates a magnetic field through a coil under a ceramic plate. When the magnetic lines of force in the magnetic field pass through the bottom of an iron pan, a stainless steel pot and the like. , produce vortex, so that the bottom of the pot quickly heats up, thus achieving the purpose of heating food.

The alternating voltage is converted into direct current by rectifier, and the direct current is converted into high-frequency alternating current exceeding audio frequency by high-frequency power conversion device, and the high-frequency alternating current is added to the flat hollow spiral induction heating coil, thus generating a high-frequency alternating magnetic field.

Its magnetic field lines penetrate the ceramic platen of the furnace and act on the metal pot. Due to electromagnetic induction, there is a strong eddy current in the pot. When the vortex flows against the internal resistance of the pot, the conversion from electric energy to heat energy is completed, and the generated Joule heat is the heat source of cooking.
