1. A cooking appliance device, comprising at least one selected from the group consisting of a controller and a regulator provided such that in a periodic continuous heating operation state, which is allocated at least one operating period, an induction target is repetitively controlled, supplied with energy and operated in a switched-on interval of the operating period with a heating power, and that in the continuous heating operating state a heating current frequency for the induction target in the switched-on interval of the operating period is varied,
wherein the at least one selected from the group consisting of a controller and a regulator is provided to apply in the continuous heating operating state a frequency spread by using a reference curve of at least one selected from the group consisting of an actual conductance and a complex conductance of a unit that has the induction target to a harmonic of one of the heating current frequencies.
