  • At least two sensor coils per induction coil may be provided and assigned to them, for example one in the middle of the induction heating coil and one in its edge region, possibly with a low coverage.
  • at least one temperature sensor can be provided per induction coil, but advantageously also two temperature sensors.
  • a temperature sensor is provided per sensor coil, wherein such a temperature sensor is arranged just close to the sensor coil.
  • a sensor coil can generally have a free region without turns, particularly advantageously in its middle region or at its center. In this free area can advantageously be arranged a temperature sensor.
  • a sensor coil and a temperature sensor together form a structural unit and although in each case have their own electrical connections, but these can optionally be combined for a faster and easier electrical connection.
  • the two parts could be sprayed, glued or potted for an integral strength.
  • a temperature sensor is arranged on the sensor coil or in its central region, but not as a structural unit and not mechanically connected thereto. Then, although the installation effort is slightly higher, but it can be installed directly and individually standard components.
  • a sensor coil as an inductive sensor or generally as a sensor can be wound flat with a maximum of two to three layers. This avoids a too large overall height for the induction hob and too large a distance between the induction heating coils and the hob plate.

  • a temperature sensor in the invention is possible in different ways. Either it is a standard component in so-called THT design with two connecting wires, which can be easily connected to the electrical conductors on the flexible support or the textile support member.

  • it may also consist of another flexible material, particularly advantageously be formed as a film carrier or conductor foil or flex circuit board with thereon applied in the usual manner printed conductors.
  • connection carrier Since during assembly of the induction cooktop, the common connection device of the flexible support must be connected to a mating connection of the induction cooktop, which usually takes place manually and requires manual gripping, it is advantageous here to use a more robust and less sensitive material than that of the textile support with it applied or sewn electrical conductors. It is possible to make the separate connection carrier much smaller than the textile carrier part, so that less is required of a more elaborate and expensive material, such as the aforementioned film carriers or flex circuit boards. The connection carrier then essentially corresponds to a type of flat cable with a certain width but very small thickness. When assembling the textile carrier part with the connection carrier, the conductor tracks of the connection carrier must then be connected to the electrical conductors on the textile carrier part.
  • contacts may be provided, in particular in the manner of contact fields. They can extend over at least a third, preferably at least half, of the length of the connection carrier.
  • they are arranged on or near at least one outer side extending in a row, advantageously on both outer sides.

  • the flexible carrier preferably has only a single such connection carrier with a total of a single connection device in the form of, for example, a plug connection device, which allows a quick and easy electrical connection.
  • an electrical contact Pressing are produced.
  • a mechanical connection can be improved by conductive adhesive or conductive paste.
  • the separate connection carrier can also be soldered, but this is usually not recommended due to the relatively high temperatures in an induction hob.

  • a recess or a hole extend through the separate connection carrier and the textile carrier part, advantageously as close as possible to the contact or the connection to be produced.
  • a not yet bent contact clip can then be performed and then U-shaped bent at least so far that the two lateral U-legs are bent toward each other while compressing the contact of the separate connection carrier and the electrical conductor of the textile support member.
  • Such a connection technology is known from the automotive sector under the keyword "splice technology", a kind of crimping technology.
  • a clamp can be bent around, so to speak, which results in an even better connection.
