Description

"Device for guiding a thrust element" State of the art Devices for guiding a sliding element, in particular for kitchen appliances such as ovens or microwaves, are already known in a wide variety of forms. The use of a solid lubricant, such as graphite, as a lubricant is also known. In known devices, the lubricant is applied to a walkway of the device. The disadvantage of this is that the lubricant is washed off the walkways after several cleaning processes of the kitchen appliance. Task and advantages of the invention The object of the invention is to provide an alternative device for guiding a sliding element, which is used in particular in an oven or microwave cooking appliance or microwave oven. The problem is solved by the features of the independent claims. Advantageous and expedient embodiments, variants and further developments of the invention are set out in the dependent claims. The invention is based on a device for guiding a sliding element which can be slidably received on a wall section by means of the device, the device comprising a fixed rail which can be fastened to the wall section and a comprising a movable rail assignable to the thrust element, wherein one rail is movable relative to the other rail. For example, the household appliance or piece of furniture has two vertically running side walls. The side walls have, for example, wall sections, wherein the device or the fixed rail of the device can be attached to a wall section. It is also conceivable that the device or the fixed rail can be attached to a side grille of an oven associated with the wall section. For example, the side grille has, for example, several horizontally running bars, wherein the side grille protrudes slightly from a wall surface of the wall section. The side grilles can, for example, be detachably inserted into the respective side walls or wall sections. For example, two devices are provided for the sliding guidance of the push element, each of which is attached to the side of the push element and to the associated side wall or wall section. For example, the push element or the side edges of the push element can be placed on the movable rails of the devices. For example, the push element is placed on the movable rail or lifted off of it to be removed. The fixed rails of the devices are, for example, connected to a wall section of the opposite side walls. The sliding element is, for example, a food carrier, a baking rack, a baking tray, a pull-out shelf or a drawer. If necessary, the device is designed as a full extension, with a middle rail between the fixed rail and the movable rail. The rails of the device are usually formed as profiles made of bent sheet metal material, e.g. as C-profiles or U-profiles. The essence of the invention is that the device comprises at least one sliding element, wherein the sliding element is made of an inorganic solid lubricant, wherein the sliding element is fixedly arranged on one rail of the device and is supported on the other rail. Because the sliding element is made of an inorganic solid lubricant, the rails can be lubricated by the movement of the rails relative to one another. In the process, a small part of the solid lubricant is removed from the sliding element by friction of the rails on the sliding element. By moving the thrust element or the movable rail relative to the fixed rail, for example, abraded particles of the solid lubricant are distributed on the rails. This improves the sliding ability of the rails, for example. For example, the sliding element is arranged on the fixed rail and is supported on the movable rail. It is also conceivable that the sliding element is arranged on the movable rail and is supported on the fixed rail. For example, the sliding element is firmly connected to the fixed rail. It is also conceivable that the sliding element is firmly connected to the movable rail. It is also conceivable that the sliding element comprises graphite. The device can preferably be arranged in baking ovens, for example in baking ovens capable of pyrolysis. It is crucial that the sliding element is suitable for temperatures of 400 ° C to 600 ° C, for example. Graphite is advantageously resistant to high temperatures, so that the graphite can be used as a lubricant in baking ovens capable of pyrolysis. Furthermore, graphite is also resistant, for example, to low temperatures. Graphite, for example, is food safe. An advantageous One of the properties of graphite is that it is resistant to common detergents. When washing, the graphite is removed from the rail, but when the movable rail is moved relative to the fixed rail, the rails can be coated with graphite again. For example, the wear of the graphite of the sliding element is very low, which means that the sliding elements are very durable. This ensures long-term lubrication of the rails. For example, there is at least one sliding element, wherein the sliding element comprises graphite or is made entirely of g
