The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising an outer housing, an inner container arranged in the outer housing with an interior for receiving refrigerated goods, and inner mounting parts, wherein the inner container has a container wall, which is foamed with the outer housing, and wherein the inner mounting parts with the container wall are connected, and a method for producing a refrigerator with an outer housing, with an inner container with a container wall, and inner mounting parts.

A refrigerator has a plurality of interior fittings in the interior. Thus, the refrigerator refrigerated goods, drawers or pull-out drawers, lamps or lighting fixtures, evaporators or evaporator holders, electrical control, etc. have. Such inner attachment parts are mounted on the container wall of the inner container of the refrigerator and connected thereto.

In general, the inner container is foamed with the outer housing and usually the inner mounting parts are fixed to foam-mounted Hinterlegteilen, for example by detent, screws or clamp on the inner container. Since these backing parts are arranged foam-side on the inner container, they must be mounted before the foaming process and it are punched in the inner container necessary. The shape and size of the punched-out depends on the size of the attached internal fixture. The gaps between the backing parts and the inner container must be laboriously sealed before the foaming process, for example by means of adhesive tape or by means of appropriate seals (2K molded parts with soft sealing lip).

If, despite this, foam enters the interior during the foaming process, it must be removed at great expense.

Foam-side backing parts are known, which protrude into the interior. In these cases, foam cores must be partially recessed and the inner container can not be completely supported at these points during the foaming interior side, so that uneven container wall surfaces may arise.

It is therefore an object of the present invention to provide a refrigeration device, in particular domestic refrigeration appliance, which is simple to manufacture, has reproducible flat surfaces and is as variable as possible with respect to the inner mounting parts.

It is another object of the present invention to provide a method by which refrigerators can be produced in a simple manner and with reproducible flat surfaces.

These objects are achieved by the refrigeration appliance, in particular household refrigeration appliance, and the method for producing refrigeration appliances as indicated in the independent claims.

Further advantageous embodiments and developments, which can be applied individually or combined with each other in a suitable manner, are the subject of the respective dependent claims or are explained in more detail in the following description.

The refrigerator according to the invention, in particular domestic refrigeration appliance, with a heat-insulated housing, comprising an outer housing, a heat insulating layer and a container walls having inner container with an interior for receiving refrigerated goods, wherein at least one of the container walls are attached to a living carrier components, and wherein the carrier in a is arranged towards the interior open Aufnahmische.

The refrigerator comprises in particular an outer housing, an inner container arranged in the outer housing with an interior for receiving refrigerated goods, and inner mounting parts, wherein the inner container has a container wall, which is foamed with the outer housing, and wherein the inner mounting parts are connected to the container wall, sees a multi-function carrier on which the inner mounting parts are attached and which is mounted on the inner side of the inner container.

The carrier may be formed of multi-function carrier.

With the help of the multi-function carrier, a variety of different interior attachments can be attached to the inner container. Interior add-on parts can be refrigerated goods, Excerpts, lamps, lighting brackets, evaporators, evaporator brackets, electrical controls, etc. be.

The multifunction carrier is used on the inside, i. not on the foam side, but on the opposite side of the inner container, mounted on the inner container from the interior.

The assembly of the multi-function carrier can be done before the foaming process, so that pass through the container wall cross-fitting parts of the multifunction carrier with the foam in contact and thereby fixed.

The at least one fastening receptacle, in particular the at least one opening, may be provided in a side wall of the receiving recess parallel to the container wall, wherein in particular the multifunctional support is latched to the receptacle.

The multifunction carrier may be formed, for example, by recesses e.g. inserted through punched holes or holes in the container wall of the inner container and held there. The multifunction carrier can be clamped, snapped, snapped or glued.

The exact positioning of the multifunction carrier takes place on the tightened contour of the inner container. Since the contour is formed by the drawing tool used for the production of the inner container, the contour is very precisely predetermined and independent of the wall thickness of the inner container. Any necessary openings from which the foam could get into the interior, can be easily closed by means of lids or caps.

During assembly of the multifunction carrier before the foaming process, the multifunctional carrier is pressed against the foam pressure by the foam pressure generated during the foaming process against a supporting tool, ie the so-called foaming core or a tool inserted into the interior of the inner container during the foaming operation. As a result, the components which counteract the foam outlet, pressed against the foam core and prevent foaming in the interior. By the foam pressure the multifunction carrier is pressed against the foaming core and thus reproducible flat surfaces can be achieved despite the foam pressure.

The multifunction carrier has corresponding receiving structures in order to accommodate a variety of different interior attachments can.

With such a foaming, it is not necessary that the support tool has a complex profiling, since the multi-function carrier and the container wall surrounding the receptacle wall flush and lie on a plane.

In a special embodiment, the container wall has a fastening receptacle, in particular an opening, with which the multifunction carrier is fastened to the container wall. The opening may be made as a borehole or as a punched-out and serves solely for receiving the multi-function carrier, so that the processing of the inner container or the container wall can be independent of the inner attachment to be fastened thereto.

The special adaptation of the attachment to the respective inner attachment is effected by the multi-function carrier itself, which has a corresponding number of different receptacles for attachment of the inner mounting parts. Advantageously, the multi-function carrier is festklippbar on the container wall or is firmly locked on this.

In a special embodiment, the multifunction carrier has a seal for sealing the container wall. A sealing of the container wall is expedient during the foaming, in order to prevent the penetration of foam into the interior during the foaming. Furthermore, a seal is advantageous in order to avoid contamination of the inner container.

An advantage of the attachment of the multi-function carrier by means of prefabricated fastening receptacles, such as openings, is that the fastening receptacle, in particular the opening, does not depend on the size or shape of the interior fixture to be fastened and thus is the same for all interior fixtures. For the mounting shots enough holes or punched holes, which can be made manually via simple Bohrschablonen. This leads to lower investment costs and the position in the inner container is more flexible selectable.

Another advantage of the multifunction carrier is that the multifunction carrier can be positioned exactly in the inner container, as all contours important for positioning are tool-dependent. For punching or drilling the accuracy of positioning depends solely on the punching system and the ability to fix the inner container from.

When embedding the multifunction carrier in a receiving tables, it is advantageous that the multi-functional carrier and the inner wall of the inner container surrounding the receiving tables lie on one plane, since this simplifies the foaming process and simplifies the design of the inner components to be mounted. In addition, a gap-free design of the inner mounting parts is given and the assembly effort in The production is reduced, since the foam-tight masking usually required is eliminated.

In a further embodiment, the multi-function carrier has a plurality of receptacles for the interior attachments. Thus, the multi-function carrier can accommodate different interior attachments, such as refrigerated goods trays, extracts, lamps, lighting brackets, evaporator, evaporator brackets or electrical controls.

The multifunction carrier can be cuboid. In particular, it has a height in a range of 20 to 80 mm, a length in a range of 20 to 200 mm, and a depth in a range of 4 to 20 mm.

The multifunction carrier may be a plastic molded part, and may for example be produced by injection molding.

The inner container may be made of plastic, for example by deep drawing. The inner container may also be made of metal, such as aluminum or an aluminum alloy.

The multifunction carrier can accommodate at least two, in particular at least three, different components. For example, the multifunction carrier can accommodate a refrigerated goods bin, a lamp and an extract for a drawer.

Advantageously, the container wall closes flush with the multifunction carrier fixed in the receiving table with the multifunction carrier. This simplifies the design of the inner mounting parts in a significant way and thus also allows a simpler cleaning of the inner container when the inner mounting parts are detached from the multi-function carrier.

Advantageously, the inner mounting parts are releasably connected to the multifunction carrier.

In a further embodiment, the multifunction carrier is releasably connected to the container wall. A detachable connection of the multifunction carrier can simplify the cleanability of the container wall or of the inner container.

The multifunction carrier can also be foamed with the inner container. For this purpose, the fastening receptacles of the container wall for receiving the multi-function carrier are formed as openings, so that the multifunction carrier passes through the container wall and is fixed by the foam.
