Definitions

  • the invention relates to a cooking appliance with a glass ceramic hob with several cooking zones, at least one of which is designed as a rapid cooking zone.
  • Cooking appliances with glass ceramic cooking surfaces are known and, for example, in Patent literature sufficiently described cf. e.g. DE 35 03 647 A1.
  • the cooking zones are heated at these cooking appliances usually by means of in the cooking zones below the Glass ceramic cooktop of electrical or gas-operated heating devices.
  • This can e.g. B. electrically operated contact or radiant heating elements or be a gas radiation burner.
  • the object of the invention is therefore to further develop electrically operated cooking appliances with glass ceramic cooking surfaces, that they both take advantage of cooking appliances with a continuous level Have glass ceramic hob, but on the other hand at least in a cooking zone (Rapid cooking zone) not only a quick and direct heating of the food to be heated Guts, but also a quick and inertia adjustable Allow heat to be supplied, which is otherwise not common for glass ceramic cooktops.
  • heating rate Due to the high thermal conductivity of the ceramic, the heat flow through the hot plates particularly great on the material to be heated: heating rate, reaction rate and energy utilization are particularly advantageous.
  • the high thermal conductivity of the ceramic material also prevents that Formation of multi-circuit cooking zones with diameters adapted to the cookware or roasting zones with independently switchable and controllable Sub-zones, as they have been known for years with glass ceramic cooktops, are general are in use. Neighboring zones would heat up each other.
  • Cooking appliances whose cooking zones are exclusive, as in the above-mentioned EP described, are formed by ceramic hot plates, thus have despite the mentioned advantages over cooking appliances with glass ceramic cooking surfaces and zones a number of disadvantages.
  • Ceramic hot plates are not negligible Have thermal expansion. Since a ceramic hob is thus in the Expansion, may be used, for example, with brittle materials (glass, Ceramics) no high operating temperatures occur. Alternatively, with a permanently elastic material. These permanently elastic materials are only stable up to approx. 300 ° C. Furthermore, the quench resistance lies Ceramic discs typically at a maximum of around 300 K.
  • the operating temperature of ceramic hot plates is therefore limited to around 300 ° C. To use the ceramic hotplate at these low temperatures To be able to, it is necessary to plan expensive, especially pots with a very Floor to use. In contrast, in the case of commercially available tableware the lack of planicity of the floors cooking zone temperatures up to 600 ° C needed to bring the food to be heated to the boil quickly.
  • the hotplate 1 shows a hotplate 1 which is inserted into a glass ceramic cooktop 2 is.
  • the hotplate 1 forms a so-called rapid cooking zone, while the remaining cooking zones 3, as usual with glass ceramic cooktops, by in the area of Cooking zones arranged below the glass ceramic hob 2, electrically operated Heating devices are heated.
  • Such heating devices can e.g. B. the contact or radiant heating elements described above his.
  • the joint 4 between ceramic 1 and glass ceramic 2 can be different Techniques are done.
  • the ceramic plate 1 can e.g. B. using a silicone adhesive in the corresponding recess in the glass ceramic hob is glued. It is also possible to plate 1 over a thermally insulating material (ceramic, Metal, glass). These thermal insulating materials can too serve to lower the temperature down to the joint towards the board material, so that lower voltages arise here, or bonded securely with silicone can be. Heat sinks can also be used to lower this temperature become.
  • Ceramic adhesives are also possible as a transition to glass ceramic 2 itself, or to the insulating intermediate material. Negative expansion materials can absorb tensions as joining material or there can be space be left through a space for the expansion of the ceramic. This The gap must be designed in such a way that no water or the like is created through it can penetrate into the heating area (e.g. by locally gluing in with silicone glue).
  • the structure can also be such that the glass-ceramic pane 2 a corner or half of the pane is taken out then with a different material, which has better joining properties with the ceramic disc owns, is connected.
  • this other material e.g. prestressed Glass, glass ceramic or plastic
  • the ceramic hotplate 1 is then fitted.
  • the ceramic material must have a high thermal conductivity.
  • the material also electrically insulating, e.g. B. in the case of Si 3 N 4 or SiC the heating device can be applied in a simple manner in the form of printed electrical resistors directly to the underside of the hotplate 1 itself. The energy utilization and the heating rate are then particularly high.
  • heating can be carried out using standard radiant heaters take place as they are with conventional glass ceramic cooktops Is used.
