  • the invention relates to a cooking appliance with a colored cooking surface, consisting of a glass or glass ceramic material, wherein at least one heating element and at least one luminous element are arranged in the region below the underside of the cooking surface.
  • Cooking appliances with lighting elements are known from the prior art, in which the lighting elements are used to display operating conditions.
  • Induction cooking appliances are usually formed today with a glass ceramic disk as a cooking surface.
  • other materials such as, for example, tempered soda-lime glass or borosilicate glass, can also be used as cooking surface material if thermal overheating of these temperature-sensitive materials can be avoided.
  • Cooking surfaces known from the prior art are therefore generally provided with a nap-like or similar structuring in the region of their underside.
  • a glass or glass ceramic cooking surface can not balance the energy of a falling pot by deformation of the surface, such as a metal surface it could. Rather, the energy has to be transmitted to the environment through vibrations. If she is prevented, then leads the Impact load to break the cooking surface. For this reason, cooking surfaces are installed in such a way that they can avoid shock loads, for example when a pot falls down on the cooking surface.
  • the heating elements, in particular induction coils are resiliently pressed against the underside of the cooking surface, so that they can also give in at the impact load.
  • Lighting elements are used for cooking zone marking or for visualization of operating conditions, such as cooking situations or dangerous situations. To ensure good visibility, the lighting elements should be as close as possible to the bottom of the cooking surface. Then losses due to scattering are kept low and it is possible to achieve a good image sharpness and brightness of the light-emitting elements.
  • the lighting elements themselves may u.a. be glass or glass ceramic and thereby have the property that the light emission along the length of the light element can be defined if necessary.
