Document Type and Number:
WIPO Patent Application WO/2021/172667
Kind Code:
A1
Abstract:
Disclosed is an induction heating device. The disclosed induction heating device senses whether a container placed on a heating coil is off-center, and if so, the direction in which the container is off-center, on the basis of a change in the resonance current of a plurality of sensing coils disposed along the circumferential direction above the heating coil. Each of the plurality of sensing coils includes a plurality of first layer sensing coils and a plurality of second layer sensing coils. Each of the plurality of first layer sensing coils is electrically connected to a corresponding second layer sensing coil among the plurality of second layer sensing coils. The first layer sensing coil and the second layer sensing coil that are connected to each other are vertically misaligned and have opposite winding directions.
