Induction heating cooktop

An induction heating type cooktop comprising:

• a case;
• a cover plate coupled to an upper end of the case and defining an upper plate portion for placing an object to be heated thereon;
• a single layer of working coil positioned in the case;
• a thin film coated on the upper plate portion and configured to be inductively heated by the working coil;
• and
• an adiabatic material provided between the upper plate portion and the working coil,
• wherein the working coil is configured to, based on the object being a nonmagnetic object, induce an electrical current at the thin film to thereby heat the nonmagnetic object,
• wherein the working coil is configured to, based on the object being a magnetic object, generate and provide a magnetic flux toward the magnetic object to thereby heat the magnetic object,
• wherein the working coil overlaps the thin film in a vertical direction and includes a central region,
• wherein the thin film has an open area that overlaps the central area of the working coil in a vertical direction, and
• the film is composed of one or more parts.
