    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.

    Abstract: A steam generator and a cooking apparatus having a steam generator are provided. The steam generator may include a steam generation tube; an inflow tube configured to provide a passage so that water is introduced into the steam generation tube; at least one heater disposed on an outer surface of the steam generation tube to heat the water and generate steam; a discharge tube disposed above the steam generation tube to provide a passage so that the steam is discharged; and an adaptor unit configured to branch discharge water and the steam discharged from the discharge tube. The discharge tube may have an inner diameter that gradually increases in an upward direction.
