A glass-ceramic cooktop is provided that is made of glass-ceramic material with a flat upper side and an underside. The glass-ceramic material has transmittance values of greater than 0.1% in the visible light range in the total wavelength region greater than 420 nm, a light transmittance in the visible range of 0.8-2.5%, and a transmittance of 0-85% in the infrared at 1600 nm, and wherein the glass-ceramic material has high quartz mixed crystals as the prevalent crystal phase. The underside is flat, unstructured, and coplanar with the upper side.

High-strength colored glass ceramics as a cooktop, smooth on both sides

A display device in particular for cooktops is provide that has a glass ceramic with a front side and a back side and a lamp arranged in the area of the back side. The display device further includes an optical compensation filter arranged between the front side and the lamp so as to implement any color impressions easily and inexpensively and in a preselectable manner.

Display device, in particular for cooktops

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.

Cooking apparatus having lighting elements

A display device is provided that is a transparent, colored glass-ceramic with a front-side indication side, a rear-side illumination side, and at least one luminous element disposed in the region of the illumination side. The display device further includes a color compensation filter and a at least partially transparent intermediate layer between the color compensation filter and the glass-ceramic.

Display device

A heating element is provided that has at least one flat electrical heating device to heat at least one spatial region found on one side of the heating device. The heating device has a contact configured to connect to a power supply and control device of a baking and roasting oven. The contact is configured to alternately connect to an electronic mechanism external to the baking and roasting oven. In addition, an arrangement of the heating element with an electronic mechanism external to the baking and roasting oven is provided.

Heating element

A transparent, dyed cooktop is provided that has improved color display capability. The cooktop is made of a glass ceramic having high quartz mixed crystals as the predominant crystal phase, wherein the glass ceramic comprises none of the chemical refining agents arsenic oxide and/or antimony oxide, except for inevitable trace amounts. The glass ceramic has transmission values of greater than 0.1% in the range of visible light over the entire wavelength range greater than 450 nm, light transmission in the visible range of 0.8 to 5%, and transmission in the infrared at 1600 nm of 45-85%. The glass ceramic also includes a display apparatus that has a display device which is designed to display different operating conditions with different colors and/or symbols.

An oven muffle that has at least two wall elements adjoining each other, which delimit at least some regions of an interior space that is used as a cooking chamber. The wall elements are of a glass or a glass ceramic and the adjacent wall elements are oriented at an angle with respect to one another. In an oven muffle of this invention, along with ease of cleaning, a simple structural design is achieved if the wall elements are integrally joined to one another and constitute one formed part.

Oven muffle

The method produces a reshaped glass-ceramic article by forced reshaping of a flat green glass part during a ceramicizing process with temporarily lowered viscosity due to crystallization heat. To perform the forced reshaping economically the forced reshaping takes place in a continuous oven for ceramicizing and in an oven section in which the viscosity of the green glass part is temporarily lowered as a result of crystallization heat. An apparatus for performing the process is provided in the continuous oven including different active reshaping devices and/or a hollow mold. The method produces glass-ceramic articles with undamaged surfaces corresponding to surfaces produced during the making of the green glass part (smooth or structured, e.g. knobbed).

An oven muffle having a receiving space, at least some regions of which are delimited by wall elements, in which at least one of the wall elements is permeable to IR radiation or has a region that is permeable to IR radiation. In the oven muffle, the cooking performance is successfully improved while also providing an easily cleanable interior because a reflecting element that reflects IR radiation is positioned in the region of the outer surface of the wall element on a side oriented away from the receiving space.

In the method of manufacturing a cooking stove its stove top can be equipped with different glass ceramic tops, which each have at least one cooking area, which is heated by a radiant heating body cooperating with a temperature-limiting adjusting device, which limits a surface temperature of the glass ceramic top. To economically and individually adjust the IR transmission of a glass ceramic top with a higher IR transmittance to that of a lower IR transmittance corresponding to that of another glass ceramic top so that they are interchangeable, the glass ceramic top with the higher IR transmittance is provided with an absorbing and/or reflecting coating. When the glass ceramic tops are interchangeable, either can be used in a given cooking stove without changing the expensive temperature-limiting device.
