Patent number: 10788219Abstract: 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.Type: GrantFiled: December 22, 2017Date of Patent: September 29, 2020Assignee: SCHOTT AGInventors: Martin Mueller, Thomas Zenker, Gerold Ohl, Matthias Bockmeyer, Evelin Weiss

Patent number: 10228146Abstract: 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.Type: GrantFiled: July 16, 2014Date of Patent: March 12, 2019Assignee: SCHOTT AGInventors: Thomas Zenker, Gerold Ohl, Bernd Woelfing, Ju-Young Uam, Martin Taplan
