  • the display formats of the projection field 24 differ here with respect to the current value 26 of the heating power. This can be used, for example, as a digital display or digital display ( FIG. 3A ), as a bar chart ( FIG. 3B ) or as a circle segment ( FIG. 3C ) are displayed.
  • Figure 3D shows a further embodiment for the display in the projection field 24th
  • this display format also contains a current value with respect to the heating or cooking time 36.
  • This is for example in the form of a Circular segments shown. In this case, in the circle segment 36, for example, the remaining cooking time or the already expired heating time can be displayed.
  • the cooking or heating time forms another parameter of the hotplate in the context of the invention.
  • This parameter like the heat output of the hob, can be adjusted by the user using the cookware 14, 16 on the hob.
  • the position change of the cookware 14, 16 (travel distance) determined by the cookware detection device 18 is converted or converted into a corresponding change in the value of the heating time of the cooking surface.
  • a change in the orientation of the respective cookware 14, 16 by a rotational movement cause a corresponding change in the heating power
  • a change in the position of the cookware 14, 16 can cause a corresponding change in the heating duration by a shift.
  • the projection field 24 in addition to the curved directional arrows 28 for the rotational movement, further straight directional arrows for the displacement can also be displayed.
  • the display of the current values for the heating power 26 and the heating period 36 in the projection field 24 is preferably carried out in real time, so that the user receives a direct feedback on the alignment and / or position change of the cookware 14, 16 made by him.
  • Cookware detection devices, temperature detection devices and projection devices are already known to those skilled in principle and therefore need not be explained in detail in this context. Rather, the operating device according to the invention can be realized with any such devices.
