Definitions
- the invention relates to a ceramic hob with a glass ceramic plate, which carries heating elements for direct heating on its underside, separated by an insulating layer, the cooking zone being subdivided into at least one inner and one outer zone, which carry zone-specific heating elements which are dependent on a controller the temperature values detected by the temperature sensors assigned to the subzones can be switched and / or their output can be regulated.
- a ceramic hob is known from DE 41 30 337 A1.
- the sub-zones each have a meander-shaped heating conductor, in the vicinity of which a similarly designed sensor path for temperature detection runs. In this embodiment, the heating conductors and the sensor tracks are applied to an insulation layer covering the entire cooking zone.
- the construction and application of the heating elements is difficult even if concentric, circular conductor tracks are applied to the underside of the glass ceramic plate, which extend almost 360 ° over the circumference of the partial zones.
- the glass ceramic plate forms a parallel connection of many temperature-dependent differential resistors between two conductor tracks, as shown in DE 40 22 846 A1.
- the large number of resistors can also be realized by means of many strip-shaped conductor tracks, the ends of which are connected in parallel, such as the EP 0 315 079 B1 (DE 38 84 569 T2) shows. With this design of the hob, however, no individually switchable and controllable subzones are formed.
- the conductor tracks and the surface heating elements can also be applied as silver-containing tracks or layers by means of screen printing. They can also be applied with carbon pastes.
