  • Patent number: 10788219
    Abstract: A cooktop with a graphical display device is provided. The cooktop includes a glass ceramic substrate with a dead-front effect in which lightness differences in the display area and in particular differences between the latter and the adjacent areas of the cooktop are not visible for a user from the exterior. The cooktop has a glass or glass ceramic substrate and a display device with a display surface for displaying information by emission of light, wherein the display device is in the interior of the cooktop or cooking appliance such that light emitted from the display surface passes through the glass or glass ceramic substrate and is perceptible by a user in the exterior.

  • Patent number: 10228146
    Abstract: A cooking apparatus with a cooktop composed of a glass or glass-ceramic material is provided. The cooking apparatus includes a heating element and a lighting element that are disposed in the region below the underside of the cooktop. The heating element is applied to the underside of the cooktop indirectly by a pressing device or directly by pre-stressing one or a plurality of spring elements. The lighting element and the heating element are disposed on a common support section of the pressing device in such a way that they are adjustable with an oscillation of the cooktop.

  • Publication number: 20170215231
    Abstract: A cooktop is provided that includes a glass ceramic cooking plate that exhibits enhanced mechanical strength and at the same time increased spectral transmittance in the infrared range. The glass ceramic cooking plate makes it possible to detect, through the glass ceramic cooking plate, the temperature of a piece of cookware placed thereon using an infrared sensor, and to perform an automated cooking process in response thereto.

  • Publication number: 20170215236
    Abstract: A cooktop is provided that has a glass ceramic cooking plate, at least one heater arranged below the glass ceramic cooking plate, and at least one touch sensor. The touch sensor is operable across the glass ceramic cooking plate for adjusting the power of the at least one heater. The glass ceramic cooking plate has an increased strength and is therefore produced with a reduced thickness, whereby the sensitivity and reliability of the touch sensor is significantly improved.
