Induction heating device

An induction heating device, comprising:

• a heating coil;
• a sensing part comprising a plurality of first layer sensing coils and a plurality of second layer sensing coils forming pairs of a first layer sensing coil and a second layer sensing coil that are spaced from the heating coil perpendicularly;
• and
• a controller configured to detect an eccentric placement of a container on the heating coil, based on a change in resonance current flowing in a pair of the first layer sensing coil and the second layer sensing coil in the sensing part,
• wherein each of the plurality of first layer sensing coils electrically connects to a corresponding second layer sensing coil among the plurality of second layer sensing coils, and
• the first layer sensing coil and the second layer sensing coil that connect to each other are misaligned perpendicularly with respect to each other, and are wound in opposite directions with respect to each other.
