  • the partial areas 18c, 18d are essentially of the same size.
  • the control unit 16 operates a first of the partial areas 18c as a third target temperature field and a second of the partial areas 18d as a fourth target temperature field depending on an operating input by means of the operating unit 20.
  • a mathematical function that has a step function is assigned to each of the third and fourth target temperature fields.
  • the third target temperature field has five target temperature sections 34a, 34b, 34c, 34d, 34e.
  • the fourth target temperature field has four target temperature sections 36a, 36b, 36c, 36d.

  • the control unit 16 changes the subdivision of the heating area 12 into partial areas 18 as a function of an operating input by means of the operating unit 20. For example, the control unit 16 divides the heating area 12 into two partial areas 18e in the operating state as a function of an operating input using the operating unit 20, 18f on (cf. Fig. 4 ).
  • the partial regions 18e, 18f are aligned in a column-like manner parallel to the y-axis and are arranged adjacent to one another, in particular adjacent to one another, in the x-axis.
  • the control unit 16 operates each of the partial areas 18e, 18f as a target temperature field and assigns a mathematical function to each target temperature field.
  • the mathematical function has a function that constantly changes in value along the y-axis.
  • a first of the sub-areas 18e has values of the setpoint temperature that increase substantially continuously in the y-axis.
  • a second of the sub-areas 18e 18f has essentially continuously decreasing values of the target temperature in the y-axis.
  • the control unit 16 changes between the operating mode in which the heating area 12 is used Setpoint temperature field is operated, and a further operating mode in which the heating area 12 is operated in a conventional manner.
  • the control unit 16 assigns the heating utensils 14 to a heating zone in the further operating mode.
  • the control unit 16 in the further operating mode uses the control unit 20 to issue a request for input of a heating power for the newly set-up cookware 14.
  • the control unit 16 operates the newly set up cookware 14 with the heating power input via the operating unit 20 in the further operating mode.
  • control operation is also conceivable here in order to achieve a predetermined target temperature.
  • control unit could have a control knob and / or a touch slider.
  • control unit is partially formed in one piece with a hob plate, wherein in particular operator commands and advantageously an arrangement of temperature sections of at least one target temperature field could be carried out by means of an operator input via a surface of the hob plate.
  • any combinations which appear sensible to a person skilled in the art are conceivable under the described configurations.
