Patent number: 11277888Abstract: A cooking hob includes at least one heating power transferring element with multiple concentrically arranged windings, one or more heating power energy units for powering the windings, a control unit that controls the heating power energy units, and detection means that determines the coverage of the windings by a cookware item. The control unit balances the heat provided to the cookware item by determining a rescaled electric power for the windings based on power requests and information regarding the coverage of the windings and establishes an operating cycle by determining a duty cycle for one or more windings. The duty cycle defines the activation time of the respective winding and is chosen such that the mean electric power provided to the respective winding within the operating cycle is equal or essentially equal to the rescaled electric power associated with the winding.Type: GrantFiled: June 13, 2019Date of Patent: March 15, 2022Assignee: Electrolux Appliances AktiebolagInventors: Massimo Nostro, Alex Viroli, Filippo Martini, Filippo Milanesi, Fabio Angeli, Laurent Jeanneteau
