Definitions

  • the applied sol-gel layers are also suitable for the temperatures typical in such cooking systems.
  • the Layer thicknesses are only a few ⁇ m. Owing to the sol-gel technique, the layers applied, despite their low thickness, have great stability and great adhesion both in the case of a multilayer technique on one another and on the substrate material itself, in particular metal.
  • a particularly good heat transfer from the hotplate body or to the pot and an excellent heat distribution in this regard can be achieved in that the hotplate body has an insulating protective layer in the ⁇ m range, to which the heating element is applied directly by means of thick-film technology. If necessary, the heating element can also be implemented using more complex coating processes, for example thin-film technology.
  • Fig. 4 shows the hotplate body of the cooking system according to the third embodiment
  • phase a the hotplate body 5 has a dome-shaped contour that curves downward. To change this, heat is supplied to the peripheral region of the hotplate body 5 via the second heating element 21.
  • phase b the hotplate body 5 is completely flat.
  • phase c the first heating element 17 in the region of the recess 15 is first subjected to heating power in order to curvature the hotplate body 5 to reach the bottom of the pot 6. Due to the temperature gradient present in the hotplate body 5, the hotplate body 5 bulges into the upwardly curved pot base 6 until sufficient thermal contact is made between the pot base 6 and the hotplate body 5.
