Definitions

  • the invention relates to a hob according to the preamble of claim 1.
  • Such hobs are known per se.
  • E.g. describes DE 34 33 880 A1 such a hob with a Non-metallic hotplate, preferably glass ceramic material, with below the hotplate in the Area of limited cooking zones arranged radiators, which are preferably radiant heaters acts.
  • the hotplate of this well-known hob is on their top essentially completely with one printed decorative coating or lamination. To the cooking zone heated directly by the radiator is followed by a decor-free border area.
  • the Thermal conductivity of such a hotplate glass ceramic material leaves nothing to be desired.
  • a method of making a hob with a Base shell and one that bridges the base shell Cooking plate made from a glass ceramic or a comparable material is from DE 40 22 844 C1 known. There, by means of several, from each other more independent, arranged in the area of a heating zone Temperature sensors used for a specific abnormal characteristic thermal load condition Temperature distribution in the heating surface determined and by means of Operating status indicators and / or by means of optical and / or acoustic warning devices are displayed.
  • a glass ceramic hob with a base and one the hotplate bridging the base plate from one Glass ceramic material is also, for example, from DE 35 26 783 or known from EP 0 116 861 B1.
  • EP 0 381 792 A1 is known an electric cooking device that one Sheet steel, glass, ceramic or glass ceramic existing Carrier plate has, on the underside of thick-film resistors are attached for electrical heating.
  • the Carrier plate can be used as a large plate with several Cooking areas or be designed as a single hotplate, the is provided in a built-in frame element.
  • At the The bottom of the carrier plate are also temperature sensors provided for temperature limitation and / control, which - like the heating elements - designed as film resistors are.
  • the invention has for its object a hob to create of the type mentioned, in which the Hot plate compared to hot plates made of glass ceramic material a significantly improved thermal conductivity having.
  • the hob according to the invention has the advantages of simple structure and significantly improved Thermal conduction properties of the hotplate, so that the Energy requirement for a hob according to the invention in Comparison of energy requirements for a comparable one Hob with a hotplate made of commercially available Glass ceramic material is significantly reduced, or that Heating up a cookware on the hotplate is comparatively short.
  • Figures 1 and 3 show an embodiment of the hob 10 with a base shell 12 and a base shell 12 bridging hotplate 14.
  • the base shell 12 has disc-like base part 16 and a ring part 18, the on the upper side 20 of the disk-shaped base part 16 is attached.
  • On the top 20 of the base part 16 or the base shell 12 is a resistance heating element 22 established that forms a heat radiation source.
  • the hotplate 14 consists of sintered silicon carbite, in particular from liquid phase sintered silicon carbide.
  • a arranged rod-shaped temperature sensor element 26 In from the base shell 12 and the hotplate 14 sintered silicon carbide defined space 24 is a arranged rod-shaped temperature sensor element 26, the takes advantage of the thermal expansion principle.
  • the Temperature sensor element 26 is with a switching device 28 combined on the outside of the base shell 12 under the edge region protruding beyond the base shell 12 30 of the hotplate 14 is mounted.
  • Another option is at the bottom 40 of the hotplate made of sintered silicon carbide at least to provide a temperature sensor, for example in Thick film technology can be realized.
  • This at least one temperature sensor can by means of a Shielding against the radiation of the Resistance heating element 22 to be shielded.
  • the hob 10 with a Combination of a rod-shaped temperature sensor element 26 and at least one temperature sensor of the above Way of training.
  • reference numeral 42 is one Designated connection device, by means of which the Resistance heating element 22 to a suitable energy source can be connected.
