Description

The invention relates to a method for producing a household refrigerating appliance, in which a cardboard rear wall is fastened to a device for removing condensate occurring on the domestic refrigerator. For this purpose, a lower end of the rear wall is bent and introduced and held in a receiving space of the device. Furthermore, the invention also relates to a household refrigerator with a housing which has a rear wall made of cardboard. The domestic refrigerator further comprises a device for removing condensate occurring at the domestic refrigerator, to which a bent lower end of the rear wall is held. This lower end of the rear wall extends into a receiving space of the device and is held there.

Such a design of a household refrigeration appliance is from the EP 2 295 899 A1 known. There is provided that a bottom plate of the body limits a machine room at the top. This bottom plate also defines a space in which thermal insulation material, in particular an insulation foam, is arranged. A separate collecting channel is connected to this base plate, with a rib extending downwards on a channel bottom dipping into a groove in the base plate. The integrally formed gutter comprises two sub-components which are movably connected to one another by a film hinge. In the end position of these two sections to each other a downwardly open groove is formed, in which in the assembled final state a U-shaped bent end of a cardboard formed from the rear wall is clamped.

However, this embodiment and in particular the production can only be used for specific household appliances. Especially in the case of stationary equipment, this is not possible due to the production processes.

It is an object of the present invention to provide a method for producing a household refrigerator and a household refrigerator, in which the assembly of the rear wall is simplified and is more variable with respect to the different types of household refrigerators.

This object is achieved by a method and a household refrigerator according to the independent claims. In the method according to the invention for producing a household refrigerating appliance, a cardboard rear wall is fastened to a device for removing condensate occurring on the household refrigerator. It is bent over a lower end of the rear wall and inserted into a receiving space of the device and held there. The design of cardboard creates a lightweight and cost-effective back wall, which meets the mechanical requirements and also limits the insulating foam area stable. An essential idea of the invention can be seen in the fact that the household refrigerating appliance-side device is provided with a base part and an upper wall limiting the receiving space and at least one bent boundary wall. The lower end of the rear wall is inserted into an insertion space comprising the receiving space and then an insert part separate from the base part is inserted into the insertion space. By inserting and inserting this into the insertion space, the lower end of the rear wall is bent during the removal of the insert part in the fixed to the base part end position along the boundary wall. It is thus provided in the method according to the invention, that the base part and the insert part are provided as separate components, by their joining and joining in the end position then the lower end of the rear wall is automatically bent and spent in the desired end position and thus then also between the base part and the insert part is clamped.

This procedure simplifies assembly. It is then also possible with this embodiment, that the installation of the rear wall in a plurality of different types of household appliances is possible and in particular can be used in household refrigerators designed as a stationary appliances. As a result, the entire production is simplified and thus can be carried out, for example, faster and cheaper or required manufacturing steps in stationary devices can still be performed unchanged.

By the use of space is a backward and thus external to the device exposed and accessible space and thus designed to be open to the outside, the installation of the insert can be done easily and purposefully. Even at different production times, then the insert can still be used, so that the production processes can be designed individually for different household refrigerators, as it may be advantageous in each case. The accessibility to this application space of the base part is thus longer or more extensive given during the manufacturing process and the installation of the insert part and thus the rear wall flexibilized, especially with regard to the manufacturing phase, to which then the rear wall in the final position is to be attached to this device.

It can thus be considered and implemented individual and flexible production-related requirements.

It is preferably provided that the insert part is fastened to the base part in a non-destructively releasable manner. This can also be possible at later times required loosening.

In an advantageous embodiment, the insert part is latched to the base part. As a result, a mechanically stable and resilient connection is created, which can be realized quickly on the one hand assembly technology, on the other hand then can be relatively easily solved depending on demand.

In an advantageous manufacturing step, the boundary wall is formed S-shaped in cross-section and the lower end of the rear wall is bent around an input of the application space facing front S-belly. This lower end is then inflected into a depression formed by a posterior S-belly adjacent to the anterior S-abdomen. This bent lower end of the rear wall thus then immersed in turn in a limited area, so that it is also protected there on the one hand, on the other hand is held mechanically safe by the interaction between the insert part and the base part. As a result, a cornerless, continuously curved shape of the lower end is generated and on the other hand, the further holding is easily achieved.

Preferably, an upstanding projection of the insert is inserted in inserting the insert in the base part in this trough. Characterized the bent in the end position lower end of the rear wall is supported in the direction of the front S-belly. An undesirable big game this bent end in this trough is prevented. Furthermore, this bent end is then pressed against its bending force by the base part separate insert in the direction of the base part.

Particularly advantageously, the boundary wall is formed in cross-section L-shaped and formed the L-shape as lying L. In this case, one L-leg is formed as a horizontal roof and the other L-leg is designed as a vertical front. The bending of the lower end of the rear wall is therefore particularly simple yet accurate position possible. The Umbiegevorgang is facilitated.

In particular, the insert is inserted with a rearwardly projecting projection into the insert space and a rear wall of the supernatant is applied to a space bounding the back of the application of the base part. A bottom wall of the supernatant is applied to a base of the base part which delimits the insert space at the bottom. As a result, the insert sits with a relatively large surface contact in the base part and thus is in particular two differently oriented surfaces, namely on the rear wall of the insert space and the bottom of the application space. This also allows a snug fit of the insert part in the base part.

Preferably, a drainage channel which is open towards the rear wall of cardboard is integrated into the insert part. This allows the condensate running downwards from the rear wall, which then drips off at the drip edge created by the bend of the lower end and drips directly into this gutter. As a result, an extensive collection of this condensate can be achieved without any other wetting of components with the condensate occurring undesirably.

Preferably, an outlet nozzle connected to the drainage channel for the fluid line of the condensate is formed integrally in the insert part. As a result, the condensate dripping into the downwardly open drainage channel is then led or forwarded directly out of the insert via the outlet connection. A very targeted and formed with the shortest possible route fluid drainage path for the condensate is formed. In addition, a locally targeted forwarding of the absorbed condensate into the machine room of the household refrigerating appliance is made possible by the discharge nozzle. There it can then be directed purposefully into an evaporation tray. The evaporation tray is preferably arranged adjacent to a compressor arranged in the machine room, in particular positioned above this compressor. The waste heat generated by the compressor can then be used to evaporate the condensate conducted into the evaporation tray.

Preferably, the insert part is arranged so that in the assembled end state, a U-shaped bend of the lower end of the rear wall in the vertical direction is arranged directly above the gutter. The dripping edge created in this respect at the bend is therefore very well defined and very narrow with regard to the spreading width in the depth direction of the household refrigerating appliance. Due to the direct Nachuntentropfen then fall the condensate drops directly into this gutter, whereby these relatively narrow, also viewed in the depth direction, can be formed. The whole concept can therefore be designed very space-minimized.

In an advantageous embodiment, the drain neck when attaching the insert part to the base part in a, rearwardly open, receiving groove, which is formed integrally in the base part, introduced. As a result, the gutter-shaped exposed, in particular cantilevered down, outlet nozzle is supported during assembly and unwanted bending or breaking is prevented. In addition, even in the final position of this drain pipe is held mechanically stable and positioned quasi embedded in this groove in the base part. Not least, a fundamental position assurance between the insert part and the base part is made possible by this configuration.

It is preferably provided that the insert part is integrally formed from plastic. As a result, it can be provided with very low weight and easily manufactured as an injection molded part.

Moreover, it is insensitive to the condensate by such a material design, so that no rusting or other corrosion or the like can occur.

In an advantageous embodiment, the base part is integrally formed of plastic, and then here are the advantages already mentioned above, as they were called for the insert apply.

The base part is preferably arranged on a component which is to be filled with thermally insulating material, in particular insulation foam, and / or a machine room delimiting a machine room of the household refrigerating appliance. This base part is thus preferably also a so-called Schäumtraverse that limits the engine room of the household refrigerator from above.

Furthermore, the invention also relates to a household refrigeration appliance for receiving foodstuffs, which has a housing which comprises a cardboard back wall. The domestic refrigeration appliance also includes a device for removing condensate occurring at the domestic refrigerating appliance, in particular at the rear wall. A bent lower end of the rear wall, which is thus arranged adjacent to the engine room, is held in the device. The lower end of this rear wall extends into a receiving space of the device and is held therein. An essential idea of the invention is to be seen in that the device has a base part with a limiting the upper space and at least once bent the receiving space. The lower end of the rear wall is inserted into an insertion space comprising the receiving space. The device has a separate part to the base part, which is inserted into the application space and mechanically connected to the base part. The lower end of the rear wall of cardboard is bent along this at least once bent boundary wall of the base part and the bend of this lower end is held by the insert dimensionally stable. The achievable advantages have already been mentioned above.

In an advantageous embodiment, the insert part is arranged locked on the base part.

Just by the S-shaped contour of this boundary wall of the base part and the suction of the condensate in the open cut edge, which could occur due to the capillary action is prevented.

In particular, the gutter is V-shaped and the discharge nozzle is located at the low point of the V-shape. As a result, the condensate dripping into the gutter is automatically routed to the outlet nozzle or can run there. Preferably, the two legs of the V-shape at an angle between 4 ° and 8 °, preferably 6 °, arranged inclined relative to a horizontal.

The terms "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" are the intended use and intended arrangement of the device and a then given in front of the device and given in the direction of the device observer given positions and orientations.
