Description

Domestic refrigeration appliance having a specific fastening of a cover for covering a rear part

Technical Field

The invention relates to a domestic refrigerator having a receiving chamber for food products, which is delimited by a wall of an interior container of the domestic refrigerator. Furthermore, the domestic refrigerator has a rear part which is arranged on a bore which is formed in the wall of the interior container. The back-piece is a connection between the component in the receiving chamber and a component outside the inner container. The connector is configured to couple with a component in the interior space. The domestic refrigerator has a cover which is independent of the wall and which at least partially covers the rear part on the receiving chamber side, i.e. on the interior.

Background

In modern domestic refrigeration appliances, it is known to arrange a rear part on the refrigerated goods container and thus in the interior container at several points in order to be able to insert components, such as cables or valves of a ventilator. In connection with this, electrical components which are arranged in the receiving chamber and which have to be supplied with electrical energy and/or control signals need to be coupled with the cable. Since the control unit is usually arranged outside the receiving space, for example in an electronic component shaft, the cables to the control unit must also be routed outside the inner container. In an embodiment, the cable is at least partially arranged within an intermediate space, which is filled with an insulating material, in particular an insulating foam. The inner container forms with its wall the transition between the receiving chamber and the intermediate space mentioned, and it is at these interfaces of the inner container that the rear part is particularly advantageous.

On the other hand, a cover is provided on the receiving chamber side in order to position the rear part and the components that can be coupled thereto, for example the plug or the components, in a non-exposed manner on the receiving chamber side.

In many cases, the component on the receiving chamber side and thus also the plug which can be coupled to the rear part must be spaced apart from the supplied component. The cover is therefore larger than the plug rear part itself, so that the exposed cable can also be covered. It is known to arrange and fix the cover on the rear part itself. Thus, in some embodiments, the cover is so large that the fastening only to the rear part is not sufficient. The extraction force may be excessive here. It is thus provided that the cover is additionally secured by means of screws. However, screw connections have the disadvantage that the cable can be located in the region of the screw and therefore damage to the cable can also occur when screwing in the screw.

Disclosure of Invention

The object of the invention is to provide a domestic refrigeration device in which the fastening of the cover provided for covering the rear part on the receiving chamber side is improved.

This object is achieved by a domestic refrigeration device having the features of claim 1.

One aspect of the invention relates to a domestic refrigeration appliance having at least one receiving chamber for food products. The receiving chamber is delimited by a wall of an interior container of the domestic refrigeration appliance. Furthermore, the domestic refrigerator has at least one rear part, which is arranged on a bore, which is formed in the wall of the interior container. The rear part thus forms an interface or coupling at the transition between the receiving chamber and the intermediate space outside the inner container. The rear part is a connection for connecting a component of the domestic refrigerator arranged in the receiving chamber to a separate component of a structure different from this component, outside the inner container. The connector is configured to couple with a component in the interior space. The domestic refrigeration device has a cover which is independent of the wall and which at least partially covers the rear part on the receiving chamber side. The separate holder of the domestic refrigeration device is arranged at a distance from the rear part. The holder is configured to secure the cover. The separate retainer is disposed on the wall. The holder has a holding device by means of which the cover can be fastened or fastened to the holder without screws. Screwless fastening means that the cover can be fastened to the holding device without a screw connection and held. Thus, the formation avoids the need for bolts. Thereby preventing possible damage of the cable due to the mounting bolt.

The connection of the two components through the inner container is achieved by the rear part being designed as a connection for the connection between the component of the domestic refrigeration appliance arranged in the receiving chamber and a separate component of a structure different from this component, which is external to the inner container. The rear part can be designed in particular as a cable connection in order to connect the two parts, for example, by means of electrical lines or fluid lines. For example, electrical components, such as sensors, lighting devices, display units and/or operating units, or water-conducting components, such as ice makers or water output units, are considered as components arranged in the receiving chamber. For example, electrical components, such as a control unit or a power supply unit, or water-conducting components, such as a fresh water supply, are considered as components arranged outside the inner container.

The cover, which is separate from the wall, can either cover the rear part only partially or can cover the rear part completely. A complete covering is to be understood here to mean that, in the intended use of the domestic refrigeration device, the rear part is no longer visible to the user and/or can no longer be touched by a bare hand.

In an advantageous embodiment, it is provided that the retaining device is a detent device. Thereby achieving quick mounting and dismounting of the cover. On the other hand, the latching device is also highly functional and allows a fixed mounting of the cover.

If the holding device is a latching device, it can be provided that the latching device has a curved latching element. The curved latching element can have, in particular, an arcuate outer contour in a direction perpendicular to the wall of the inner container surrounding the holder. In this way, a secure and stable fastening of the lid to the holder is also ensured when the holder is arranged so as to be rotatable about an axis perpendicular to the wall of the inner container surrounding the holder. For this purpose, the cover can have, for example, a curved opening into which the curved latching element locks, wherein the arc length of the curved opening is greater than the arc length of the curved latching element.

Preferably, it is provided that the latching device is formed on a limiting wall of the holder, which limiting wall is a component of a line holding device, which line holding device is designed to hold a line which is guided to the rear part. The latching device is therefore integrated in the holder, and additionally the line holder. Thus, certain partial elements of the line retaining device, i.e. the limiting walls, also receive the latching device. This results in a compact design of the holder, and the latching device can be integrated and thus formed in one piece on the mechanically very stable part, i.e. the limiting wall. Thereby, locking is also reliably achieved and the forces generated at the time of locking can be safely and reliably borne. Since the limiting wall itself is correspondingly stable, the locking can also be carried out targeted and safely. In this case, undesired deformations can be avoided.

Preferably, the latching device has two latching hooks which are integrally formed on the end of the limiting wall. By virtue of this exposed position of the latching hook, the other additional partial elements do not come into the way when locked and thus when coupled to the cover, so that the latching process can be carried out in a targeted and reliable manner.

Preferably, the holding part has a line holding device integrated and thus integrated, which is designed to hold a line guided to the rear part. The versatility of the holder also enables the line to be held in a positionally accurate manner and also to be guided further in a desired direction.

Preferably, the line retaining device has a limiting wall which delimits the line channel, wherein a pressure lug for pressing the at least one line into the line channel is provided on at least one limiting wall. This also prevents the line from slipping or moving out of the line channel undesirably. Thus, it is also possible to determine the bundling of a plurality of lines in the line channel.

Preferably, it is provided that the pressing tab is arranged on the limiting wall in a resiliently movable manner. This allows the pressing to be performed individually as the case may be. If several lines are contained in the line channel, the pressing can be carried out as desired by means of movable pressing webs. In each case, the line channels can be designed as well as possible in the case of a relatively large but also small number of lines provided with different thicknesses and/or different numbers. The positioning and maintenance of the line channel, which is most identically configured and equipped with lines, respectively, can be reliably achieved.

Preferably, the holder has a bayonet element, so that the holder can be mounted or mounted on the wall by means of a bayonet connection. A quick and safe fixing of the position of the holder on the wall is achieved. The bayonet connection is in particular arranged such that the final mounting position is reached by a rotational movement of one full revolution about the partial region. Avoiding more rotations and thus, as it were, spiral movements.

Preferably, it is provided that the bayonet elements are arranged integrally on the base of the holder and are thus formed integrally with the base. As a result, the bayonet elements are permanently positioned in a positionally accurate manner and are also mechanically stable in this connection. The assembly effort for individually fixing the bayonet elements to the base can likewise be saved. Furthermore, the production of the holder, in particular as an integral plastic component, can be realized particularly easily.

Preferably, the base forms a boundary of the line channel.

The holder is in particular a separate component with respect to the inner container. The holder is preferably of one-piece, in particular of one-piece material construction.

The holder can be arranged substantially only on the receiving chamber side, i.e. on the interior space side. Preferably, however, the holder is arranged on and extends at least partially through the passage in the wall of the inner container. The passage is preferably arranged independently of the bore to which the rear part is fastened. Both the through-opening and the hole are preferably surrounded by a circumferential edge.

In an advantageous embodiment, it is provided that the holding element has an annular collar as a sealing flange which, in the installed state of the holding element in the passage in the wall, bears against the wall. In a particularly advantageous manner, it is thereby avoided that an insulating material, in particular an insulating foam, may emerge via the hole in which the holder is located and may reach from outside the inner container into the receiving chamber. Furthermore, a further stabilization of the position of the holder is achieved by the sealing flange and the abutment of the sealing flange against the wall.

Preferably, the rear part is designed for coupling with an electrical plug, which is a corresponding component in the receiving chamber. In particular, a coupling that can be released without damage is provided here.

In an advantageous embodiment, it can be provided that the cover is additionally fastened to the rear part. In particular, a screwless fastening is also provided here. For example, a latching connection can also be provided here.

The domestic refrigeration appliance preferably has two separate receiving chambers, wherein one receiving chamber is a refrigerating compartment and the other receiving chamber is a freezing compartment. Preferably, the refrigeration compartment is configured above the freezing compartment, viewed in the height direction of the domestic refrigeration device. The upper receiving space associated therewith can preferably be closed by two separate doors which are each arranged on the housing so as to be pivotable about a vertical axis of rotation. The two doors are arranged in the closed state on a common plane and are arranged side by side in the width direction, in particular also in a non-overlapping manner with respect to one another. In particular, the further receiving chamber located below it in the height direction can be closed by a door separate from it. The door may be a front wall of a drawer that can be pushed into and pulled out of the second receiving chamber.

A further independent aspect of the invention relates to a domestic refrigeration appliance having at least one receiving chamber for food products. The receiving chamber is delimited by a wall of an interior container of the domestic refrigeration appliance. Furthermore, the domestic refrigerator has at least one rear part, which is arranged on a bore which is formed in the wall of the interior container. The rear part thus forms an interface or a coupling at the transition between the receiving chamber and the intermediate space outside the inner container. The rear part is a connection for connecting a component of the domestic refrigeration device arranged in the receiving chamber to a separate component, which is configured outside the inner container and is different from this component. The connector is configured to couple with a component in the interior space. The domestic refrigerator has a cover which is independent of the wall and which covers at least the rear part on the receiving chamber side. The separate holder of the domestic refrigeration appliance is arranged at a distance from the rear-mounted part. The holder is configured to secure the cover. The separate retainer is disposed on the wall. The holder has bayonet elements so that the holder can be mounted on the wall by means of a bayonet connection. This configuration makes it possible to mount the holder on the wall particularly easily, but with a defined position. In this case, a quick mounting can be carried out without a screw connection.

The rear part can be designed in particular in one piece, preferably in one piece. The rear part can in particular be made of plastic.

Detailed Description

Fig. 1 shows a schematic illustration of a domestic refrigeration device 1, which is designed for storing and preserving food. The domestic refrigerator 1 can be a refrigerator or freezer or a combination refrigerator and freezer. In the embodiment shown, the domestic refrigeration appliance is a combination refrigerator-freezer appliance. The domestic refrigeration device 1 has a housing 2 in which a first receiving chamber 3 is formed, which is here illustrated as a refrigerating compartment. Furthermore, a second receiving chamber 4, which is separate from the first receiving chamber 3 and is here exemplary a freezer compartment, is formed in the housing 2. As can be seen from fig. 1, the two receiving chambers 3 and 4 are formed one above the other in the height direction (y direction) of the domestic refrigeration device 1. In this embodiment, the upper receiving chamber 3 can be closed from the front side by two separate doors 5 and 6. The two doors 5 and 6 are each pivotably mounted on the housing 2 via a vertical axis. In the closed state of the doors 5 and 6, the doors are arranged side by side, in particular without overlapping, with respect to one another and extend in a common plane. The further receiving space 4 can be closed by a further door 7, wherein the door 7 is preferably a front wall of a drawer which is mounted in the housing 2 so as to be movable in the depth direction (z direction).

The domestic refrigeration appliance 1 preferably has at least one component, in particular a plurality of components, which are arranged in the receiving chamber 3 and/or in the receiving chamber 4 and which have to be supplied with electrical energy and/or control signals. For this purpose, corresponding wired connections, in particular cables, are routed. The control unit and/or the energy source required for this purpose are arranged outside the inner container 8, which delimits the receiving chambers 3 and/or 4 with its walls and is arranged in the housing 2. The mentioned cable connections can thus be routed from outside the inner container 8 into the receiving chambers 3 and/or 4.

For this purpose, it is provided that, as shown in an enlarged view in fig. 2, a corresponding connection is formed on the wall of the inner container 8. The wall in this connection can be, for example, the

vertical side walls

9a, 9b, the rear wall 9c, the top wall 9d or the bottom wall 9e of the inner container 9. In this embodiment, the exemplarily enumerated walls define the boundaries of the receiving chamber 3. Accordingly, walls delimiting the receiving chamber 4 can of course also be cited.

Fig. 2 shows an exemplary wall 10, which may be, for example, a side wall 9b, in which an aperture 11 is formed. A rear piece 12 is arranged over the hole 11. For this purpose, a holding device 13 can be provided, which can be a stop or a latching element. Outside the inner container 8, the lines run in the form of cables to the rear piece 12. The rear part 12 forms an electrical interface to a plug, not shown here, which is releasably coupled to the rear part 12 without damage. At the plug, the cable on the receiving chamber side then extends to the mentioned components in the receiving chamber 3. The component may for example be a light source or a ventilator or the like. In principle, the components in the receiving chambers 3, 4 can be all components which in particular have to be supplied with electrical signals.

As can be seen in fig. 2, in an advantageous embodiment a recess 14 is formed in the wall 10, in which recess the hole 11 is formed.

As can also be seen in fig. 2, a further hole 15 is formed in the wall 10, in particular in the recess 14, at a distance from the hole 11. A retaining member 16, which is a separate, integral piece of plastic, is secured in this aperture 15. In this exemplary embodiment, it is thus provided that, viewed in the height direction, the holding element 16 is arranged below the rear element 12 and thus at a distance from the latter. A cover 17 (fig. 6), which is not shown in fig. 2 and is preferably plate-shaped, can be fastened to the holder 16 without damage and without release. The separate cover 17 arranged on the receiving chamber side thus covers the rear part 12 and also the holder 16 toward the receiving chamber 3.

In particular, it is provided that the cover 17 is fastened to the holder 16 without screws and thus without screw connections. It can be provided that the cover 17 is additionally also fastened to the rear part 12. In the embodiment described, it is then also preferably provided that the cover 17 is fastened to the rear part 12 without screws, for example by means of a snap-fit connection.

Fig. 3 shows the view according to fig. 2, wherein the already laid and fixed line 18 is additionally shown here. The line 18 extends as far as a plug 36, which is coupled to the rear part 12. Furthermore, the line 18 is also held on the holder 16. The holder 16 has a line holding device 19 for this purpose. The line 18 running on the receiving chamber side is thus also held on the holder 16 after the cover 17.

One embodiment of the retainer 16 is shown in perspective view in fig. 4. The holder 16 is designed as a one-piece plastic component, in particular as an injection-molded component. The holder has a base 20. The base 20 is an integral part of the line retention device 19, since it delimits the line channel 21 as a bottom wall. Two spaced apart and in particular parallel extending limiting

walls

22 and 23 are formed as far as the base 20. The limiting

walls

22 and 23 are also part of the line retaining device 19 and in connection therewith laterally delimit the line channel 21. As can also be seen, the pressure lugs 24, 25 are molded on the inner sides of the limiting

walls

22 and 23 facing each other, said pressure lugs being oriented toward each other and obliquely downward toward the base 20. The

pressing tabs

24 and 25 are movably arranged on the limiting

walls

22 and 23. The lines 18 held in the line channels 21 are pressed downwards towards the base 20 by the

pressing tabs

24 and 25, so that a corresponding fixing and lashing takes place.

Furthermore, it is provided that the holder 16 has a latching device 26 as a holding device, which has latching

elements

27 and 28 as a component. The latching

elements

27 and 28 are integrally formed on the free ends of the limiting

walls

22 and 23. The free end faces away from the base 20. The latching

elements

27 and 28 are designed as outwardly projecting latching hooks or latching strips. The cover 27 is latched to the holder 16 by the latching device 26, as is also shown in fig. 6. The latching

elements

27 and 28 pass through

openings

29 and 30 in the cover 17, as shown in fig. 6.

It can also be seen in fig. 4 that the holding part 16 has a handle web 31, by means of which the holding part 16 can be inserted into the opening 15 and can then be fixed thereto by a rotational movement relative to the wall 10. In particular, for this purpose, the holder 16 has

bayonet elements

32 and 33, which form a bayonet connection 34 with corresponding elements on the wall 10 (fig. 2 and 3). For example, it can be provided that the holder 16 is first pushed into the opening 15 in the guide position and then brought into the final installation position by a specific rotational movement of less than a full rotation, for example only a quarter rotation.

In a further advantageous embodiment, it is provided that the holder 16 has a collar 35 which is of completely annular design. This flange 35 is designed as a sealing flange and in the installed state rests against the outside of the wall 10. The insulating material, in particular the insulating foam, which is introduced into the intermediate space between the inner container 8 and the outer shell of the housing 2 after the mounting of the holding element 16, cannot therefore pass through the opening 15 into the receiving chamber 3.

In the embodiment shown in fig. 4, the flange 35 is configured annularly around the base 20 and extends as far as the wall of the base 20. Furthermore, in the exemplary embodiment in fig. 4, it can be seen that the latching

elements

27 and 28 are of rectilinear design and therefore do not have a curvature about the longitudinal axis a of the clamping part 16.

A further embodiment of the holder 16 is shown in fig. 5. In contrast to the configuration according to fig. 4, the latching

elements

27 and 28 are curved and are thus curved about the longitudinal axis a. In this exemplary embodiment, it is also provided that the pressure lugs 24 and 25 are designed in a stepped manner on the edges facing one another, so that a mutual engagement and thus a certain engagement is also achieved. In the example in fig. 4, curved latching

elements

27 and 28 and/or stepped pressure lugs 24 can also be provided. In the mounted state of the cover 17, at least the rear piece 12 and the holder 16 are covered on the receiving chamber side. It may be provided that the cover 17 has such a planar dimension that it covers the entire recess 14.

During installation, it is first provided that the rear part 12 is fixed in the opening 11. The cables running outside the receiving chamber 3 extend as far as the rear piece 12. A holder 16 is also mounted, wherein it can also be mounted on the wall 10 before the rear part 12. After this installation, an insulating material can be introduced outside the inner container 8, so that the holder 16 and the rear piece 12 outside the receiving chamber 3 are also covered by the insulating foam. In particular, the lines 18 can then be routed on the receiving chamber side in addition thereto. After the line 18 is then also fixed to the line holding device 19 of the holder 16, the cover 17 can then be snapped onto the holder 16 in a further subsequent step. Preferably, a cover 17 can also be additionally fastened to the rear part 12 on the receiving chamber side.

If the holder 16 is not exactly arranged in its final installation position in the bore 11, however, a straight and vertically upright positioning of the cover 17 is also possible by the curved embodiment of the latching

elements

27 and 28, since a vertical positional orientation of the cover 17 is also achieved by this curvature and in particular the corresponding complementary curvature of the

passages

29 and 30.

In addition or alternatively, a hose for conducting a gaseous or liquid medium can also be provided as a further line, and in particular the hose is also held on the receiving chamber side on the holder 16.
