Abstract (en)
[origin: WO2022013008A1] The invention relates to a hob apparatus (10a; 10b; 10c), in particular an induction hob apparatus, having: at least one heating unit (12a; 12b); at least one sensor unit (14a; 14b; 14c), which is separate from the heating unit (12a; 12b), has at least one electric resonant circuit (16a) and is provided for detecting at least one sensor signal (18a; 18c); and a control unit (20a; 20c), which is provided for controlling the sensor unit (14a; 14b; 14c) and analysing the sensor signal (18a; 18c). In order to provide a hob apparatus with improved user comfort properties, according to the invention the control unit (20a; 20c) determines, in an operating state, at least one state variable (22a; 22c) relating to the heating unit (12a; 12b) on the basis of a phase shift (24a; 24c) and/or an amplitude ratio between the sensor signal (18a; 18c) and one further signal.
