Definitions
- the invention relates to a window glass of glass ceramic for fireplaces or stoves.
- the window can also consist of a glass with low thermal expansion, in particular borosilicate glass, if the temperature in the furnace is not too high.
- fireplaces or stoves which are becoming increasingly popular in the home, typically have a privacy screen coupled to the door to the combustion chamber.
- the screen is in a known manner predominantly of a colorless glass ceramic.
- a glass ceramic material suitable for this purpose is commercially available, for example, under the brand ROBAX®. But even a borosilicate glass, which is under the brand BOROFLOAT® commercially, is suitable.
- the starting material in a glass-ceramic privacy screen is in each case a flat glass pane in various thicknesses of 2 to 10 mm, which is deformed by known processes and then ceramized.
- Decorations can be applied to the inside and outside of the screen.
- the screen may be provided with functional and designerischen coatings (one-sided or two-sided).
- functional and designerischen coatings one-sided or two-sided.
- corresponding holes are provided in the glass or glass-ceramic privacy screen.
- FIG. 4 shows such a construction according to the prior art.
- the viewing window 1 is held in a door frame, which consists of an outer metal frame 3 and an inner metal frame 5, which are connected to each other via a screw 6.
- the viewing window rests against the outer metal frame 3 via an outer seal 2 and an inner seal 4 against the inner metal frame 5.
- the different temperature / time loads due to the fire in the combustion chamber affect the different materials such as steel or glass ceramic. Due to the different coefficients of expansion of the different materials it comes thereby twisting and / or to a delay of the door frame, which leads to an increased risk of breakage of the lens.
- the invention has for its object to reduce the risk of breakage of the glass-ceramic pane by reducing torsional forces of the door frame on the glass ceramic pane in an existing door frame construction of the glass or glass-ceramic window of a fireplace or stove. It should be possible that the door frame construction can be maintained and possibly only the heat-resistant sealing material must be replaced. In the case of a frameless glass-ceramic viewing window, in particular its weight should be reduced.
- this measure is achieved by a circumferential facet grinding of the layer disc on the edge of the lens.
- the heat conduction in the edge region is reduced transversely to the lens, since the disc is thinner in this area and thus the cross section of the lens is reduced. This effect reduces the temperature of the door frame.
- the standard thicknesses for glass-ceramic privacy screens are 3, 4 and 5 mm.
- EP 0 496 243 B1 is an oven door with a protective screen for a microwave oven known, which has a plastic frame with flush inserted transparent polycarbonate disc, which is tapered towards the edge, has.
- the critical, in particular thermal edge loads as in the case of glass or glass ceramic panes of chimney or stove doors in the case of the invention do not occur in the known oven door.
- the surface of the facet can be used in polished and polished condition. Glass ceramic plates with a circumferential facet cut are in themselves. The surface of the facet can be used in polished and polished condition.
- FIG. 1 shows such an embodiment with a flat glass or glass ceramic pane 1, which, according to FIG. 3, is enclosed in a frame 3 and has a peripheral facet 1 '.
- the screen can also be deformed.
- Various processes can be used for forming, such as bending or gravity sinking.
- Curved lenses can be easily, ie once 90 ° or more times, for example, be bent by 90 ° twice, ie they have flat surfaces that are angled over a small radius, for example, about 5 mm.
- Fig. 2 is such on both sides by 90 ° angled screen, which is faceted in the angled surfaces 1 a, 1 b, is shown.
- Circular shaped lenses may also be provided in different radii with edge faceting, as well as multi-dimensionally deformed discs (e.g., a spherical cap portion) and discs that are circularly and angularly deformed in combination.
- the faceting is preferably carried out already in the precursor glass, also called green glass.
- the pane is then reshaped and then ceramized.
- the ceramization can be carried out by appropriate temperature / time programs until the formation of high quartz mixed crystals or until the formation of Keatitmischkristallen which give the screen a translucent (milky) appearance.
- the lens can be decorated or undecorated in the area of the facet. Further facets in the lens are conceivable as a design element at every point.
- the multiple refraction of the light by means of the facet edge enhances the brilliance of the flames in the combustion chamber and is pronounced of the light effects of a diamond in the light.
- the lens is completely visible.
- the lens gives a fine visual impression through the edge itself.
- the thickness reduction on the edge has the advantage that the side impact risk and thus the risk of breakage is reduced due to reduced attack surface.
