Definitions

  • the invention relates to an induction hob according to the preamble of claim 1 and to a method for operating an induction hob according to the preamble of claim 14.
  • Induction hobs with multiple inductors are known in the art.
  • the cooktop comprises a large number of inductors, which are arranged in a matrix or in a grid and can be flexibly combined to form freely definable heating zones.
  • Each inductor is uniquely associated with an inverter that generates a high frequency heating current to operate the inductor.
  • a frequency of the heating current can be set by a control unit of the induction hob independently of the heating frequency of the other inductors.
  • an induction hob is also known, in which via a switching device optionally one of two inductors can be connected to a single inverter. Furthermore, it is possible to use multiple inverters simultaneously to operate the inductors of a single, large heating zone.
  • the invention is based on the object of designing a generic induction cooktop in a particularly cost-effective manner.
  • the object is solved by the features of the independent claims, while advantageous refinements and developments of the invention result from the subclaims.
  • the invention is based on an induction hob with a number of inductors and a number of inverters for supplying the inductors with a heating current via a respective circuit and with a switching device for closing and interrupting the circuit.
  • the switching device is adapted to connect the inductors from a group in different switching positions with different inverters.
  • the necessary number of inverters and low-pass filters can be reduced.
  • the reduced number of inverters can be compensated by a flexible switching device that allows flexible assignment of the inductors to the inverters. By the switching device, an independent control of the inductors can be achieved within a group and two or more heating zones can be heated by inductors from the same group of inductors.
  • the inductors combined into a heating zone are operated synchronously, in a fixed phase relationship and at the same heating frequency, in order to avoid interferences.
  • a single inverter would be sufficient.
  • this apparently contradicts the requirement of free reconfigurability of the heating zones, which is usually provided in such applications. It has therefore developed the technical prejudice that an independent operation of the inductors and thus a flexible adaptation of a shape and size of the heating zones to be heated to a cookware element can only be achieved if each inverter is associated with an inductor and vice versa.
  • the invention is based on the finding that sufficiently flexible operation of a generic induction hob can be achieved even if the number of inverters is less than the number of inductors.
  • the omission of the inverters, in particular in induction hobs with a large number of inductors significant cost savings can be achieved.
  • the switching device which allows a more flexible association between the inverters and the inductors, the apparent losses in the flexibility of the induction hob can be easily compensated.
  • the advantages of the invention are particularly useful in induction cooktops with a high number of inductors, for example in induction cooktops with at least 16 inductors, and in particular when the inductors are arranged in a matrix form or in a grid.
  • the induction hob comprises a plurality of groups of inductors, wherein the inductors of at least one of the groups are hardwired to an inverter or can be connected via the switching device only with exactly one inverter.
  • inductors which lie in corner areas or at the edge of the induction hob are combined virtually exclusively together with the inductors directly adjacent to these inductors to form a heating zone. Therefore, independent operation of these inductors does not have to be made possible, and switching devices that would allow such independent operation and connect the respective inductors to different inverters can be saved.
  • the switching device connects each of the inductors with exactly one inverter associated with this inductor.
  • the inverter can therefore feed one or more inductors depending on a switching position of the switching device, while the inductor is uniquely associated with an inverter.
  • the various inductors assigned to an inverter may be adjacent inductors.
  • the various inductors assigned to an inverter may be adjacent inductors.
  • the induction hob comprises a plurality of groups each having a plurality of inductors.
  • the switching device may then be configured to connect each of the inductors from a group to an inverter that is common to all of the inductors in the group.
  • a control unit of the induction hob can be designed to detect a cookware element and select inductors from the group depending on at least one position of the cookware element.
  • the selected inductors are connected to the inverter via the switching device while the remaining inductors can remain inactive.
  • a selection within the group can take place and the induction hob according to the invention is in terms of flexibility an induction hob with a larger number of inverters in nothing.
  • inductors can in particular be combined to form a preassembled module with a common inductor carrier.
  • the resulting modularity in the design of the hob leads to increased flexibility in the design.
  • the preassembled module comprises a part of the switching device assigned to the corresponding group of inductors.
  • a cost-effective production of a hob according to the invention can be achieved if the induction hob comprises a plurality of identical modules, each designed for heating of at most one or two heating zones.
  • the induction hob comprises a plurality of identical modules, each designed for heating of at most one or two heating zones.
  • not all inductors of the group used for heating the heating zone but only a part of the inductors can be selected and activated by an actuation of the switching device.
  • the induction hob comprises a plurality of groups of inductors, the inductors of the group being connected to a common capacitor forming a resonant circuit together with the inductor of the inductors.
  • the inductors are then preferably connected in parallel between the switching device and the capacitor.
  • the switching device is designed to connect at least a subset of the inductors in different switching positions with different inverters. This can be particularly advantageous if the inductors in edge regions between two localized groups of inductors can be flexibly assigned to one or the other group or the one or the other inverter.
  • inductors can be supplied from the edge region of a module by an inverter of an adjacent module with heating current.
  • the concept of the invention is applicable not only in connection with matrix cooktops having a multiplicity of similar inductors arranged in a matrix or a grid, but also in induction cooktops with concentric inductors, which are switched on or off depending on a detected diameter of a cookware element can.
  • the concentric inductors can then be supplied by the same inverter, so that the number of inverters is smaller than the number of inductors.
  • the induction hob comprises a control unit which is designed for the detection of one or more cookware elements.
  • the control unit can assign a heating zone to each of the cookware elements, or flexibly define the heating zone depending on a size and position of the detected cookware element.
