An induction hob has a hob plate, a plurality of induction heating coils arranged under the hob plate and a plurality of sensor coils arranged under the hob plate. The induction heating coils are rectangular, wherein at least two induction heating coils are arranged one behind the other and at least three induction heating coils are arranged one next to the other. Two adjacent induction heating coils form an adjacent region with one another in which the two induction heating coils lie with their adjacent sides. At least one sensor coil is arranged in each adjacent region, wherein precisely a single sensor coil is provided in a spacing direction from the one induction heating coil to the adjacent induction heating coil.

Induction hob and method for controlling an induction hob

An arrangement for controlling induction coils of an induction cooking hob so as to minimize noise production resulting from intermodulation of certain frequencies of operation. The induction coils are operated in two modes, with a first mode at the same frequency fso to produce a low intermodulation or differential frequency, or at a second mode having a high differential frequency of about 18 kHz. Alternating back and forth between said modes of operation makes it possible to reach predefined average values for the power of the induction coils for a given time period, while at the same time minimizing development of disturbing noise.
