An induction heating device includes: a case; working coils; a base plate that supports the working coils; light guides that are installed on the base plate and that cover outer portions of each working coil; light emitting elements disposed below the light guides and configured to emit light; and an indicator substrate that is disposed below the base plate and that seats the light emitting elements. The indicator substrate includes a first indicator substrate, where a first portion of the light emitting elements are arranged along outer portions of the first indicator substrate, and a second indicator substrate disposed at a rear side of the first indicator substrate, where a second portion of the light emitting elements are arranged along outer portions of the second indicator substrate except for an outer portion at a front side that is adjacent to and faces the rear side of the first indicator substrate.

The present invention relates to an illumination device (12) for a heating zone (10) of a cooking hob, in particular of an induction cooking hob. The illumination device (12) comprises at least one light source element (14) and at least one reflecting element (18). Further, the illumination device (12) comprises at least one insulating layer (18) horizontally arrangeable or arranged on the heating zone (10). Said insulating layer (18) includes at least one light channel (20) formed as a cut-out. The illumination device (12) comprises at least one reflecting, diffusing and/or refracting layer covering at least the light channel (20). The light source element (14) and the reflecting element (16) are arranged that a light beam from said light source element (14) is redirected by the reflecting element (16) into the light channel (20).

A cooking device includes a light unit and an insulation unit configured to electrically insulate the light unit. The insulation unit includes a first insulation element and a second insulation element, with the light unit being at least partially arranged between the first insulation element and the second insulation element.

An induction heating type cooktop includes a case, a cover plate that is connected to an upper end of the case and that has an upper surface configured to support an object to be heated, a working coil disposed inside the case, a thin layer disposed at the cover plate and configured to be heated by the working coil through induction, and a working coil cooling fan configured to blow air toward the working coil.

A wireless induction heating cooker is configured to be operated on an induction heating apparatus.
