Abstract
An induction heating type cooktop includes: a case, a cover plate coupled to a top of the case and having an upper plate that is configured to support a target object, a thin film disposed on at least one of a top of the upper plate or a bottom of the upper plate, a working coil provided in the case and configured to inductively heat the thin film, a memory storing information on one or more correlations between a temperature of the thin film and a plurality of components of an equivalent circuit associated with the thin film, the plurality of components including an inductor component and a resistor component, and a controller configured to operate the working coil and determine estimated temperature information corresponding to the inductor component and the resistor component of the equivalent circuit.
