  • Patent number: 10433375
    Abstract: 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.
    Type: Grant

  • Patent number: 9144116
    Abstract: In an induction heating device having an induction coil for an induction hob, the induction coil may be of flat or planar design and have at least one peripheral coil turn comprising coil wire. The outer contour of the induction coil or the outermost coil turn may be approximately trapezoidal having two sides of equal length which are situated opposite one another and may be straight, and having two short sides of differing length between the sides of equal length.

  • Patent number: 6828530
    Abstract: An illuminating apparatus for an induction coil of an induction cooking field is in the form of a ⅓ circular ring segment and carries conducting tracks, which form turns of a coil, which is connected to several LEDs. During induction coil operation an alternating voltage is induced in the coil and consequently the LEDs are supplied. With such an illuminating apparatus it is possible without additional wiring expenditure to illuminate an induction coil under a glass ceramic cooking field.
