Abstract: An induction heating device includes a case, a cover plate, a working coil, a base plate, a light guide that is located around the working coil and includes a light-emitting surface that indicates an output intensity of the working coil or an operation state of the working coil, and a light-emitting element that emits light toward the light guide. The light guide includes a light-guiding portion that has a lower surface having a parabolic shape and an upper surface including the light-emitting surface in which the upper surface extends in a first direction farther than the lower surface, and a light-guiding support that couples to the base plate, that surrounds at least a portion of the light-guiding portion, and that reflects, toward the light-guiding portion, at least one of light that has been emitted from the light-emitting element or light that has been guided through the light-guiding portion.

Abstract: An induction heating type cooktop includes a cover plate, a working coil, a thin film, an additional metal film, and an insulator. The cover plate is coupled to a top of a case and includes an upper plate configured to place an object to be heated. The working coil is disposed in the case and configured to heat the object. The thin film is disposed on the upper plate. The additional metal film forms an equivalent circuit with the thin film and the object so as to allow an induced current by the working coil to be induced into the object arranged at the upper plate. The insulator is disposed between a bottom surface of the upper plate and the working coil.
