Abstract:
An induction heating type cooktop includes a cover plate that is coupled to a top of a case and that includes an upper plate configured to seat an object to be heated, a working coil disposed inside the case and configured to heat the object, an insulator disposed between a bottom surface of the upper plate and the working coil, and a thin film that is disposed on at least one of a top surface of the upper plate or the bottom surface of the upper plate and that includes a plurality of sub-films that are arranged about a central portion of the thin film. An outer boundary of one of the plurality of sub-films is positioned radially outward of an outer boundary of another of the plurality of sub-films relative to the central portion of the thin film.
