Description

Domestic refrigeration appliance with point and / or line contact

bearing support means

The invention relates to a household refrigerating appliance, comprising an inner container, a limited cooling space from the inner container, a cooling chamber temperature-controlling refrigeration cycle system, and at least one pair of opposing support means, which are designed to store a fitting part of the household refrigeration appliance in the cold room with lateral edge portions of the equipment on the support means in such a way that the fitting can be pulled out of the cold room and / or pushed into the cold room.

EP 1 030 146 A2 describes a cooling device with at least one cooling chamber which is arranged within its heat-insulating housing and can be closed by a door, in which intermediate shelves are provided for depositing refrigerated goods, of which at least one intermediate shelf is guided on the side walls by guides on its side edges the refrigerator is movably movable in a drawer, wherein the guides are designed as lateral support legs of an at least U-shaped supporting skeleton, which is mounted with its lateral support legs detachably on the side walls of the cooling space. The object of the invention is to provide a household refrigeration appliance, which ensures a reliable, in particular trouble-free extraction and / or insertion of a stored in the cold room equipment part.

The object of the invention is achieved by a household refrigerating appliance, comprising an inner container, a cooling chamber delimited by the inner container, a refrigeration chamber temperature-controlling refrigeration cycle system, and at least one pair of opposing support means, which are formed, a fitting part of the household refrigerator in the cold room with lateral edge portions of the equipment part on the To support means to rest resting, such that the piece of equipment can be pulled out of the cold room and / or push into the cold room, each support means has at least three supports which are formed to wear the equipment part at least substantially point and / or line contact. The refrigeration cycle system may be formed in a manner known to those skilled in the art. Thus, in addition to refrigerant pipelines, the refrigeration cycle system can in particular have an electrically drivable compressor, a throttle, such as a capillary tube or an expansion valve, a condenser (condenser), and at least one evaporator and a control device controlling these components. The at least one evaporator can be designed and / or configured to cool a freezer compartment to a temperature below 0 degrees Celsius, in particular to a temperature of approximately minus 18 degrees Celsius. The opposite support means may be arranged on two side walls, between which the equipment part is mounted in the cold room, in particular in a freezer compartment. In each case, a support means is arranged on each one of the two side walls. The support means may be integrally formed with the respective side wall.

The piece of equipment may for example be a shelf, in particular a plastic compartment floor or en glass shelf. However, the piece of equipment can also be a refrigerated goods drawer or a Eisstückbereiter or Eisstückeschale a complete Eisstückbereiter Eisstückebereitungsvorrichtung. The respective equipment part is so stored in the cold room, especially in a freezer that it can be pulled out of the cold room and / or can be pushed into the cold room. The piece of equipment can be completely removed from the domestic refrigerator manually and non-destructively. But the piece of equipment can also be installed as far as firmly in the household refrigerator, it is indeed pulled out like a drawer and / or pushed, but can not be removed from the household refrigerator without tools to remove.

Under support storage devices are understood by means of which the equipment part on top of the supports hang up or is set to support the equipment part against falling and so to keep the equipment part within the cold room, especially within a freezer in its height position. On the supports, however, the equipment part is slidably mounted so that The fitting can be pulled out of the cold room and / or pushed into the cold room.

An at least substantially point and / or line touching contact is given in particular when the equipment part is supported by eliminating support surfaces by the supports or by Punktauflager (support points) and / or Linienauflager (support lines) is worn. The terms "point-touching" and "line-touching" can be understood in the context of the invention in the sense of the Hertzian pressure. In this case, even under a point contact and / or line contact, the small contact surface which actually results can be considered to be plane and small with respect to the dimensions of the body, i. be defined the dimensions of the support.

Usually, plastic components are guided on continuous guide rails, in which the movable component is guided over the entire surface of these continuous guide rails. For equipment which are used for example in the freezer, it can lead to serious icing. When using water, e.g. When filling ice cube molds in ice makers, it is common for water spills to linger on the guide surfaces due to spillage or filling at the faucet. When inserting the equipment in the cold room or in the freezer then there is a risk that this spray, or a water film or water drops freeze and then along the guide rails enter into a fixed connection between the moving parts, so that the equipment part freezes on the guide rails and as a result can not be moved. The parts freeze together and can be partly solved by thawing. Also by icing, e.g. Condensation of the humidity and subsequent icing on open, can freeze the guide elements.

With the support means designed according to the invention no water or only in extremely small amounts of water remain on the supports of the support means, so that a freezing is no longer possible, or because of only a very small amount of water, the piece of equipment still slightly at the expense of only a small Pull-out force can be released manually. An example of an invention trained support means are curved guide elements in which the water is discharged immediately due to gravity, before it can freeze between the fitting and the guide, ie the support means. A profile in which the guide only takes place at the tangency point by means of point support is particularly favorable. By attaching several supports in a row, a sufficient guidance is given, the user of the household refrigerating appliance notes in use substantially no difference to continuous rails.

The opposing support means may be disposed on the facing inner sides of two lateral side walls of the inner container, wherein the equipment part is formed by a trained for pulling out and / or pushing in shelf and / or formed by a pulled out and / or pushing in Kühlgutschublade.

In an alternative embodiment of another household refrigerating appliance or the same household refrigerating appliance, the opposing carrying means can be arranged on mutually facing inner sides of two lateral side walls of a housing of a Eisstückebereiters stored in the household refrigerator, wherein the equipment part of an ice making device of the Eisstückebereiters and / or trained for pulling out and / or pushing in formed for pulling out and / or pushing in Eisstückeschale the Eisstückebereiters.

In each embodiment, each support means may have three or more than three supports whose at least substantially punctiform and / or line touching the fitting supporting bearing points or support lines are arranged in a common plane, in particular in a common horizontal plane or line.

By each support means having three or more than three supports, the piece of equipment can be drawer-like pulled out and / or pushed. The three or more than three supports of the suspension means constitute a substitute for a continuous rail. The three or more than three supports can therefore be designed to guide the equipment part in its displacement movement. The three or more than three supports are therefore not just for holding the in the Household refrigeration device inserted equipment part, but accordingly form to some extent a sliding bearing, which is designed for drawer-like pulling and / or pushing in the equipment part.

Each support can generally be formed by in each case at least one projection, the upwardly facing surface of which has at least one support point or support line supporting the equipment part at least essentially point and / or line contact, and the other surface sections are formed sloping. Each projection engages under an edge portion of the shelf, an edge portion of the refrigerated goods drawer or the ice making device or the Eisstückeschale. It can therefore be provided accordingly three or more than three projections per page. If a piece of equipment such as the shelf, the refrigerated goods drawer or the ice making device or the Eisstückeschale partially pulled out or only partially pushed, so one or more projections may be exposed, i. the piece of equipment is removed from the respective projection, and remain of at least two projections, which are sufficient to support the equipment stable part.

The upwardly facing surface of the projection may be curved convex, in particular arcuate or circular arc convexly curved.

By the upwardly facing surface of the projection is convexly curved, in particular arcuate or circular arc convexly curved, water, i. For example, water droplets from such surfaces can easily drain away by gravity without the risk of freezing.

However, the upwardly facing surface of the projection may also have at least one planar surface portion which is oriented inclined from a horizontal orientation.

By having the upwardly facing surface of the projection at least one flat surface portion which is oriented inclined from a horizontal orientation, water, ie can in the same way Drops of water from such surfaces in a simple manner by gravity drain away immediately without the risk of freezing exists.

The opposing support means may be arranged on the mutually facing inner sides of two lateral plastic side walls of the inner container, or the opposite support means may be arranged on facing inner sides of two lateral plastic side walls of a housing of a mounted in the household refrigerator Eisstückebereiters, wherein the opposite support means made of plastic, in particular in one piece the plastic side walls of the inner container or the housing can be formed.

By the opposing support means are arranged on mutually facing inner sides of two lateral plastic side walls of a housing of a Eisstückebereiters mounted in the household refrigerator, wherein the opposite support means are also made of plastic and integrally formed on the plastic side walls of the inner container or the housing, separate support means can be omitted. In addition, freezing of water or water droplets is less likely if the support means, in particular the supports or protrusions made of plastic, as would be the case if they were made for example of metal, where there would be a higher risk of frostbite.

The opposite support means may additionally comprise at least one, in particular a plurality of guide projections, which are in particular at least one, in particular several or all supports associated and are arranged at a vertical distance to the supports such that a fitting part during insertion between each of the underside of a guide projection and the surface of the associated support is centered.

In such an embodiment, in each case one of the guide projections can be arranged directly above each of the supports at a distance therefrom. The distance between each such guide projection and the associated support may substantially correspond to the thickness of the guided equipment part. For example, the distance of the thickness of edge portions, such as guide ribs of the ice making device or the Eisstückeschale the Eisstückebereiters correspond. In the same or analogous manner to the supports, the guide projections may have sloping surface sections. The upwardly facing surfaces of the guide projections may accordingly be formed obliquely or convexly, in particular arcuately or arcuately convexly curved, so that water can drain from the guide projections.

In order to facilitate insertion of the guide ribs of the equipment part to be inserted, in particular the ice making device or the Eisstückeschale the Eisstückebereiters, the guide projections may have undersides which extend with respect to the surfaces of the support the adjusting gap between them against the insertion direction, so that the guide ribs of the equipment during the insertion between each of the underside of a guide projection and the surface of the associated support are centered. This facilitates the insertion of the equipment part and prevents tilting of the equipment part of the projecting supports or the projecting guide projections.

The cold room may in particular be a freezer compartment of the household refrigerator. The household refrigerating appliance may comprise at least one Eisstückebereiter stored in the refrigerating room, comprising a housing, a freely rotatable in the housing about a pivot axis to a first stop by a rotation angle and beyond twistable by a twist angle Eisstückeformträger and to the Eisstückeformträger a torque-coupled manual actuating means has, which is designed for pivoting and twisting the Eisstückeformträgers from a filling position in an ejection position, wherein the opposite support means are arranged on mutually facing inner sides of two lateral side walls of the housing of Eisstückebereiters. In general, this type of leadership in all items of equipment that are used in the freezer, preferably used, as this freezing, easier undressing and better tuning of the guide ribs to the guided part or drawer is possible. The Eisstückebereiter may in particular be a mechanical Eisstückebereiter. The cold room may in particular be a freezer compartment. In the cold room or in the freezer compartment, a shelf can be arranged and a storage device can be designed to store the mechanical Eisstückebereiter below the shelf.
