  • An inductive coupling is understood to be the coupling of a primary coil of the operating device and a secondary coil of the attachment device via an alternating magnetic field, which is generated by the primary coil and tapped by the secondary coil.
  • an induction voltage is generated by means of the alternating magnetic field, which can be used to operate the attachment device.
  • Primary coil and secondary coil can also be considered as two halves of a separable transformer, which is why this type of coupling and power transmission is also called "transformer coupling".

  • the operating device base station
  • the operating device is adapted to transmit an operating power to the attachment device positioned at the work zone by means of inductive coupling.
  • the operating device may, for example, be present as a compact unit or be equipped with at least one separate working zone, which is or can be operated via a control device (common in the case of several work zones).

  • the receiver can in particular be arranged closer to its work zone assigned to it than to another work zone.

  • a transmitter is generally understood to mean a transmitting device for access to a transmission channel to the receiver.

  • the transmitter and the receiver can operate on the same or the same data protocol (s) and use a same frequency band or bands.
  • the transmitter can advantageously be set up to be fed by means of the operating power transmitted by the operating device. This means that the transmitter can only transmit if the attachment can draw power from the transformer coupling.
  • the attachment device has at least one secondary coil for continuously receiving energy from the alternating magnetic field, in general: an electromagnetic excitation field. From the magnetic alternating field inductive absorbed energy is used on the one hand to power the cooking appliance (operation of a heating element, etc.) and on the other hand to power at least the transmitter and possibly other low-voltage components such as integrated circuits.

  • the operating device is preferably designed such that a distance between two cooking zones is so great that an attachment device can only be operated on a single working zone.
  • Presence of a set top device on an active work zone can then be detected by receiving data at the receiver associated with the work zone. Because the receiver receives data, means that an attachment device can pick up power from the alternating magnetic field and therefore must be in the near field of the working zone to operate the transmitter. The presence of an attachment device can thus be easily and reliably detected without dedicated attachment detection device (weight sensor, etc.) or position determination.
  • a short-range transmitter may be used whose range is so low that its data is received only by the recipient of the associated work zone, but not by receivers associated with other work zones.

  • the integrated circuit can thus process data, for. B. read, modify, link, caching, format, etc., and output this data or derived data to the transmitter for transmission to an external unit.
