Definitions
- 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.

At a maximum transmission ⁇ 25%, the view is also denied from the outside even in the case of light irradiation.
- An inventive cooking appliance is such that the cooking surface is provided in the region of its top and / or bottom with a coating.
- the coating may have functional properties, wherein it prevents, for example, in a transparent or semi-transparent cooking surface, a view of the arranged under the cooking surface internals. Additionally or alternatively, the coating can also be used for optical decoration.
- the coating is provided with recesses in the area of the lighting elements, so that it forms a mask.
- a light-scattering element for example in the form of a roughening, preferably a coating, in particular an organic or ceramic coating, a scattering element, for example a scattering film, a scattering glass or ceramic plate or a diffusing plastic film, attached.
- the aforementioned coatings can be formed using: sol-gel materials, silicones, silicone resins, epoxy resins, methacrylates, polyurethane.
- ceramic components (color) pigments or scattering particles can be used.
- the light-diffusing element may be or may be an intermediate support. Examples of indirect carriers are glasses, glass ceramics or films, which in turn may be provided with organic and / or ceramic coatings.

- the optical compensation filter can now be matched to the material of the cooking surface, that ultimately the desired color appearance on the display side of the cooking surface can be generated. In this way, in particular cost-effective lighting elements using, for example, LEDs can be used.
- optical Compensation filters can be used to filter films or it may be suitable filter materials directly coated on the underside of the cooking surface or be placed directly in front of the light emitting element / LED or be integrated in the light guide or attached to the light guide.

It is also conceivable that differently colored LEDs emit their light from two different locations in the light guide in order to illuminate this in different colors. It is also conceivable to use adapted LEDs, which compensate for a color shift through the colored cooking surface to the effect that the desired color is visible on the top of the cooking surface. This may be the original color of the LED but also a different color from the original light source. It is also conceivable to set a color filter directly in front of the light source or to design the light element accordingly as a filter. In this case, in particular, the task can be fulfilled, according to which the color shift by the colored cooking surface varies, in particular can be compensated, whereby in particular the original color of the LED is generated again or another hue is generated selectively.
