Abstract (en)
[origin: WO2021244860A1] The invention relates to a domestic appliance device (10a-e), in particular a cooking appliance device, comprising at least one control unit (12a-e) which is provided to control at least one induction target (14a-e) repetitively with a switching frequency (16a-e) and to supply same with power. According to the invention, in order to provide a generic device with improved efficiency, the control unit (12a-e), in an operating state, modulates the switching frequency (16a-e) within a modulation period (18a-e) which corresponds to an integer multiple of a half period duration (20a-e) of a mains AC voltage (22a-e), by means of at least one frequency modulation.
