Description

Induction cooker that heats evenly

[technical field]

The utility model relates to an electromagnetic cooker, in particular to an electromagnetic cooker with multiple heating points and capable of uniform heating.

[Background technique]

The current induction cooker generally has only one heating point, that is, a coil disk for heating is arranged in the furnace shell of the induction cooker, and when food needs to be cooked, the metal container is placed on the coil disk.

The intensity of the magnetic field-induced eddy current is related to the radius of the coil disk. It is the largest at the center of the coil disk and the smallest at the edge of the coil disk. Therefore, the center of the coil disk corresponds to the thermal comparison of the metal container. Fast and high temperature, so that the temperature of the bottom center of the metal container is higher than that of the surroundings, and the heating of the metal container is uneven.
