Claim of US Patent No. 10,694,589

1. An induction hob device, comprising:at least one induction heating element adapted to heat a cooking utensil;
at least one detection circuit cooperating with the at least one induction heating element to detect a presence of the cooking utensil, said at least one detection circuit being directly connected to the at least one induction heating element irrespective of an operating state, said at least one detection circuit being configured to change at least one detection parameter of the at least one detection circuit;
at least one heat frequency unit which comprises a plurality of damping capacitors connected in series and is configured to supply the at least one induction heating element;
a control unit configured to determine at least one cooking utensil parameter as a function of a natural frequency change of the at least one detection circuit;
at least one power current supply unit which is configured to supply the at least one induction heating element; and
at least one sensor current supply unit which is configured supply the at least one detection circuit and is embodied separately from the at least one power currently supply unit.
