Abstract
An induction heating device includes: a working coil including a conducting wire that is wound in an annular shape and that is connected to a plurality of electric terminals; a ferrite core disposed vertically below the working coil and configured to direct upward an alternating magnetic field generated by the working coil, the ferrite core defining a stepped portion at each corner of the ferrite core; a base plate that supports the ferrite core on an upper surface of the base plate and that defines a connection hole having a shape corresponding to the corner of the ferrite core; and an indicator substrate disposed vertically below the base plate. The indicator substrate includes a connector that is disposed on an upper surface of the indicator substrate, that is coupled to one or more of the plurality of electric terminals, and that protrudes upward through the connection hole.
