Abstract (en)

[origin: WO2022233661A1] The invention relates to an induction hob device (10) having - at least one sensor unit (12) which is provided for identifying at least one state variable (16) relating to a heating unit (14) and which has an electrical resonant circuit (18) for detecting at least one sensor signal (20), and - a control unit (22) which is provided to determine the state variable (16) on the basis of at least one relative variable (24, 26) between the sensor signal (20) and a reference signal (28). In order to improve usability, according to the invention, the sensor unit (12) has a lock-in amplifier circuit (30) which is provided to modify the sensor signal (20) and/or the reference signal (28) in order to detect the relative variable (24, 26).
