Description

[0001] The invention relates to a household refrigeration appliance according to the preamble of claim 1 and a method for manufacturing a household refrigeration appliance according to the preamble of claim 12.

[0002] A wide variety of household refrigeration appliances, such as refrigerators, freezers, fridge-freezers, and the like, are already known from the prior art. Known household refrigeration appliances typically have an outer casing and at least one inner container arranged within the outer casing, which forms at least one refrigeration compartment. An insulating space between the outer casing and the inner container is known to be filled with thermally insulating foam. In known household refrigeration appliances, the cooling units located within the refrigeration compartment have a width that essentially corresponds to the width of the refrigeration compartment, although in many cases with particularly wide refrigeration compartments, cooling units with a narrower width would also be sufficient to provide the required cooling capacity.In the case of a refrigeration unit with a significantly narrower width than the refrigerator compartment, a problem has arisen: the inner container must be specially shaped to accommodate the unit, creating large cavities in the insulation space, particularly in the corners. If the insulation space were filled with expanding foam in these areas, foam would accumulate, leading to negative effects such as visible indentations in the outer casing and / or reduced insulation performance. Therefore, to meet customer demand for household refrigerators with refrigerator compartments of varying widths, it has been necessary to adapt the refrigeration units to the specific width of each compartment, resulting in increased development effort and higher costs.

[0004] JP 2016 180518 A discloses a refrigeration device comprising a vacuum insulation element arranged in an insulation area.

[0005] JP 2013 249973 A discloses a refrigeration device comprising an outer casing, an inner casing and insulating material arranged between them, in which a vacuum insulation panel is located.

[0006] EP 0 545 192 A1 discloses a refrigeration device comprising expanded polyurethane as insulation material, wherein separating elements are provided for dividing the insulation material.

[0007] EP 0 188 806 A2 discloses a heat-insulated body comprising open-pore polyurethane.

[0008] US 10 533 697 B2 discloses a refrigeration device with an inner casing, an outer casing and heat-insulating walls in which vacuum insulation elements are provided.

[0009] The object of the invention is to provide a generic device with improved flexibility. This object is achieved according to the invention by the features of claims 1 and 12, while advantageous embodiments and further developments of the

[0010] The invention can be seen in the dependent claims.

[0011] The invention relates to a household refrigeration appliance device with an outer casing, with at least one inner container unit arranged inside the outer casing, which has at least one inner container which forms at least one refrigeration compartment, and with an insulation element, in particular foamed in situ, which is arranged in an insulation space between the outer casing and at least one inner container.

[0012] It is proposed that the domestic refrigeration appliance have at least one filling element, in particular a filling profile element, which is arranged in the insulation compartment and is specifically designed to minimize foam accumulation when the insulation compartment is filled with thermally insulating foam. Such a design allows for a domestic refrigeration appliance with a high degree of flexibility. In particular, flexibility regarding the use of refrigeration units can be advantageously increased by enabling the use of refrigeration units of the same type and width in various domestic refrigeration appliances with refrigeration compartments of different widths, provided that a filling element is arranged in the insulation compartment that prevents foam accumulation and the associated negative effects mentioned above.This can advantageously simplify the development and manufacturing process. Furthermore, economies of scale can lead to increased cost efficiency. In addition, the filling element can also provide a high level of insulation, particularly when designed as a vacuum insulation panel.

[0013] The term "household refrigeration device" refers to at least a part, in particular a subassembly, of a household refrigeration appliance. A household appliance designed as a household refrigeration device is particularly advantageous for cooling goods, especially foodstuffs such as beverages, meat, fish, milk, and / or dairy products, in at least one operating state, particularly to extend the shelf life of the refrigerated goods. The household refrigeration appliance incorporating the household refrigeration device may, in particular, be a chest freezer, a wine storage cabinet, and / or advantageously a refrigerator and / or freezer.

[0014] The outer casing of the domestic refrigeration appliance is preferably designed to define and / or form at least a large part of the appliance's external shape. The outer casing has at least one side wall, advantageously at least two, and / or at least one rear wall, and / or at least one top wall, and / or at least one bottom wall. The outer casing is preferably made of a sheet of metal alloy, for example, steel, and / or an aluminum alloy, and manufactured using a sheet metal forming process. Alternatively, however, it would also be conceivable for the outer casing to be made of plastic and manufactured, for example, by injection molding, 3D printing, or deep drawing.

[0015] The inner container unit of the household refrigeration appliance comprises at least one inner container and may also comprise at least one further inner container. The inner container unit may be made of metal. Preferably, the inner container unit is made of plastic. The inner container unit may be manufactured, for example, by injection molding, 3D printing, sheet metal forming, or preferably by deep drawing.

[0016] The household refrigeration appliance comprises at least the refrigeration compartment formed by the inner container and may also have at least one further refrigeration compartment. The refrigeration compartment and / or the further refrigeration compartment may be configured as a refrigerator compartment, a freezer compartment, or a so-called "switching compartment," which is reversible and can provide either the function of a refrigerator compartment or a freezer compartment as needed.

[0017] The outer casing and the inner container unit are arranged in an assembled state such that the insulation space is located between the outer casing and at least one inner container of the inner container unit. Preferably, exactly one continuous insulation space is arranged between the outer casing and the inner container unit, allowing for simple foaming of the insulation space with the insulating element. However, it would also be conceivable to arrange a plurality of at least two spatially separated insulation spaces between the outer casing and the inner container unit, each containing an insulating element, preferably one foamed in situ.The insulating element has a thermal conductivity of at most 1 W / (m*K), in particular at most 0.5 W / (m*K), advantageously at most 0.1 W / (m*K), particularly advantageously at most 0.05 W / (m*K), preferably at most 0.04 W / (m*K), and particularly preferably at most 0.03 W / (m*K). The insulating element consists, in particular, at least to a large extent of a material that can be processed, in particular, into a sheet material, advantageously into an insulating sheet material. For example, the insulating element could consist at least to a large extent of foam glass and / or cork and / or Calostat and / or aerogel and / or cellulose. Advantageously, the insulating element consists at least to a large extent of at least 70%, in particular at least 80%, advantageously at least 90%, and preferably at least 95% of polyurethane (PUR) and / or expanded polystyrene (EPS) and / or expanded polypropylene (EPP).

[0018] The household appliance has at least one filling element arranged in the insulation space and may furthermore have at least one additional filling element arranged in the insulation space. The filling element and / or the additional filling element preferably have an elongated shape, wherein a largest lateral dimension is at least 50% larger than the next largest lateral dimension. Preferably, the filling element and / or the additional filling element is arranged in the insulation space such that the largest lateral dimension runs at least substantially parallel to a vertical direction of the inner container, with a deviation of at most 8°, preferably at most 5°, and particularly preferably at most 2°. However, it would also be conceivable for the filling element to have a shape other than an elongated one.Furthermore, the filling element can have a shape that is specifically adapted to a geometry in the insulation space, in particular to an outer contour of the inner container unit and / or the outer housing.

[0019] The term "intended" should be understood to mean specifically designed and / or equipped. The fact that an object is intended for a specific function should preferably be understood to mean that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0020] Furthermore, according to the invention, the inner container forms at least one receiving contour for receiving a refrigeration unit. This advantageously allows the refrigeration unit to be received using simple technical means. According to the invention, the at least one receiving contour comprises at least one snap-fit ​​receptacle, which is designed to enable a snap-fit ​​connection between the refrigeration unit and the inner container and to engage with at least one snap-fit ​​element of the refrigeration unit. Preferably, the receiving contour has a shape that allows the refrigeration unit to be received in such a way that, in a mounted state, a side surface of the refrigeration unit facing the refrigeration compartment is flush with the inner container and forms at least part of a wall bounding the refrigeration compartment.

[0021] Furthermore, it is proposed that the filling element be arranged in a corner region of the insulation chamber. This advantageously minimizes foam accumulation in the corner region when the insulation chamber is filled with the insulation element. Preferably, the corner region has the shape of an imaginary cuboid running parallel to a vertical direction of the outer housing, with a first longest side edge running along an inner edge facing the insulation chamber between a side wall and the rear wall of the outer housing, and a second longest side edge diagonally opposite the first side edge, running along an outer edge facing the insulation chamber between the receiving contour and a wall of the inner container running parallel to the rear wall of the outer housing.

[0022] Furthermore, according to the invention, the household refrigeration appliance includes the refrigeration unit. It is further proposed that the width of the refrigeration unit be smaller than the width of the refrigerated compartment.

[0023] This can advantageously improve cost efficiency. A specific type of refrigeration unit with a defined width can be advantageously used in various household refrigeration appliances with refrigerator compartments of different widths. This can advantageously reduce development costs and increase cost efficiency. The width of the refrigeration unit advantageously corresponds to at most 95%, preferably at most 90%, and particularly preferably at most 85% of the width of the refrigerator compartment.

[0024] Furthermore, it is proposed that the household refrigeration appliance device have at least one adhesive element, which is positioned at least partially between the filling element and the inner container and connects them to each other in a materially bonded manner. This design advantageously allows the filling element to be connected to the inner container using simple technical means. In addition, it advantageously ensures precise positioning of the filling element within the insulation space, so that foam accumulation can be effectively and deliberately prevented when the insulation space is filled with foam. The adhesive element can, for example, be designed as a double-sided adhesive tape or as an adhesive layer made of a substance such as hot melt adhesive or the like.The term "materially bonded" means that the mass components are held together by atomic or molecular forces, such as in soldering, welding, gluing and / or vulcanizing.

[0025] Furthermore, it is proposed that the household refrigeration appliance device has at least one adhesive element, in particular another adhesive element, which is arranged at least partially between the filling element and the outer casing and connects them together, in particular by a material bond. If the household refrigeration appliance device has an adhesive element which is arranged at least partially between the filling element and the outer casing and connects them together, the filling element can advantageously be arranged at a distance from the inner container in the insulation space, whereby the receiving contour of the inner container is advantageously completely surrounded by the insulation element, thus ensuring secure mounting of the refrigeration unit.The adhesive element can bond the filler element and the outer casing together and can be designed, for example, as a double-sided adhesive tape or as an adhesive layer made of glue, such as hot glue or the like. Alternatively or additionally, the adhesive element could bond the filler element and the outer casing together in a form-fit or force-fit manner, whereby the adhesive element can be designed, for example, as a screw, nail, rivet, clamping element, or the like.

[0026] According to the invention, the filling element has at least one recess through which the insulating element contacts the receiving contour of the inner container. This design advantageously allows the refrigeration unit to be attached to the receiving contour using simple technical means. Furthermore, the insulating effect can be advantageously improved. According to the invention, the recess allows the locking mechanism of the receiving contour of the inner container to contact the insulating element.

[0027] Furthermore, it is proposed that the inner container unit form at least one additional cooling compartment, wherein the filling element extends in a vertical direction at least partially along one outer surface of the cooling compartment and at least partially along another outer surface of the additional cooling compartment. This advantageously simplifies the manufacture of the household refrigeration appliance, since particularly large cavities that arise in the insulation space, especially in the area of ​​the outer surface of the cooling compartment and the other outer surface of the additional cooling compartment, can be advantageously covered by a single filling element.

[0028] Furthermore, it is proposed that the filling element have a higher density than the insulating element. Such a design advantageously ensures, using simple technical means, that the filling element can withstand the pressure exerted by the insulating element during the foaming of the insulation chamber. Moreover, shrinkage of the filling element can be effectively prevented. This advantageously provides a household refrigeration appliance with improved durability. Preferably, the density of the filling element is at least 10%, and particularly preferably at least 15%, higher than the density of the insulating element.

[0029] Furthermore, it is proposed that the filling element comprise polystyrene, in particular expanded polystyrene. This advantageously allows for particularly cost-effective production of the filling element. Moreover, the geometry of the filling element can be adapted particularly easily to various geometries of insulation spaces. Furthermore, a particularly reliable connection between the insulation element and the filling element can be advantageously achieved if the filling element comprises polystyrene, thereby ensuring a particularly reliable insulation effect. Preferably, the filling element is made at least substantially entirely of polystyrene, particularly preferably of expanded polystyrene. Alternatively, it would be conceivable for the molded part to comprise polyurethane, and in particular to be made at least substantially entirely of polyurethane.In this context, "at least substantially complete" shall be understood to mean a mass and / or volume fraction of at least 75%, preferably at least 85% and particularly preferably at least 90%.

[0030] Furthermore, it is proposed that the filling element be designed as a vacuum insulation panel. Such a design advantageously improves the insulation effect and thus provides a particularly energy-efficient domestic refrigeration appliance. The filling element designed as a vacuum insulation panel preferably has an evacuable support core made of an open-pore material, for example, a hardened plastic foam, in particular expanded polystyrene, and / or a microfiber material and / or pyrogenic silicon dioxide and / or perlite. The filling element designed as a vacuum insulation panel preferably has a protective cover that hermetically encloses the support core.The protective cover is preferably made of a metallized plastic film, for example, an aluminum-coated film made of polyester and / or polyamide and / or polypropylene and / or polyethylene and / or the like. The filling element, designed as a vacuum insulation panel, can, in addition to the supporting core and the protective cover, include further elements, in particular so-called dryers and / or getters, which are intended to bind water vapor and / or gas molecules, for example, oxygen and / or nitrogen and / or carbon dioxide molecules. The filling element, designed as a vacuum insulation panel, advantageously has a thermal conductivity of at most 0.008 W / (m K), particularly advantageously at most 0.006 W / (m K), preferably at most 0.004 W / (m K), and most preferably at most 0.003 W / (m K).

[0031] Furthermore, it is proposed that the filling element comprise cellulose, in particular corrugated board and / or honeycomb board. This allows the filling element to be advantageously produced with particularly low material usage and at a particularly low cost. A filling element with low temperature sensitivity and high compressive strength can also be advantageously provided if the filling element comprises cellulose. In addition, a filling element with high insulating properties can be advantageously used. Preferably, the filling element is made at least substantially entirely of cellulose, in particular corrugated board and / or honeycomb board.

[0032] The invention further relates to a household refrigeration appliance, in particular a freezer and / or refrigerator, with at least one household refrigeration device according to one of the embodiments described above. Such a household refrigeration appliance is characterized in particular by the aforementioned advantageous properties of the household refrigeration device, which, among other things, makes it possible to provide a household refrigeration appliance with a particularly high degree of flexibility in manufacturing and a particularly high insulation effect.

[0033] The invention further relates to a method for manufacturing a household refrigeration appliance, according to one of the embodiments described above, with at least one inner container unit arranged within the outer casing, which has at least one inner container which forms at least one refrigeration compartment and at least one receiving contour for receiving a refrigeration unit, and with an insulation element, in particular foamed in situ, which is arranged in an insulation space between the outer casing and at least one inner container.

[0034] It is intended that at least one filling element be arranged in the insulation space, particularly to minimize foam accumulation when the insulation space is filled with the insulating element. Such a method can advantageously prevent the formation of foam accumulation in the insulation space. Thus, a particularly safe and / or reliable method for manufacturing a household appliance can be provided, in which production defects due to distortions in the outer casing caused by foam accumulation can be advantageously minimized. A method with a particularly high degree of material and / or cost efficiency can therefore be advantageously provided.

[0035] Furthermore, it is proposed that the filling element be arranged in the insulation space before the insulation element is introduced into the insulation space, particularly by foaming. Such a method can advantageously and particularly effectively prevent the formation of foam accumulations in the insulation space.

[0036] Further advantages become apparent from the following description of the drawings. The drawings illustrate three exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. A person skilled in the art will expediently consider the features individually and combine them into meaningful further combinations.

[0037] They show: Fig. 1 a household refrigeration appliance with a household refrigeration device in a schematic view, Fig. 2 a schematic perspective sectional view of the household refrigeration device with an outer casing, an inner container unit and a filling element in a partially assembled state, Fig. 3 a schematic partial sectional view of the inner container unit with an inner container which forms a receiving contour for receiving a refrigeration unit of the household appliance, Fig. 4 a schematic perspective sectional view of the household refrigeration device in a fully assembled state with an insulating element which is arranged in an insulating space between the outer casing and the inner container, Fig. 5 a schematic perspective view of the inner container unit with the filling element and an adhesive element which connects both together by material bonding, Fig.Fig. 6 a schematic diagram illustrating a method for manufacturing a household refrigeration appliance, Fig. 7 a further embodiment of a household refrigeration appliance with an inner container unit and a filling element in a schematic perspective view, and Fig. 8 a further embodiment of a household refrigeration appliance with an outer casing, an inner container unit, and a filling element in a schematic perspective view.

[0038] Figure 1 Figure 1 shows a household refrigeration appliance 50a in a schematic perspective view. The household refrigeration appliance 50a is designed as a refrigerator-freezer combination. The household refrigeration appliance 50a has a household refrigeration device 10a. The household refrigeration device 10a comprises an outer casing 12a, which defines at least a large part of the external shape of the household appliance 50a.

[0039] Figure 2Figure 1 shows the household refrigeration appliance 10a with the outer casing 12a and with an inner container unit 14a in a schematic perspective partial sectional view through the outer casing 12a and the inner container unit 14a in a partially assembled state. The inner container unit 14a is arranged inside the outer casing 12a. The inner container unit 14a has at least one inner container 16a. The inner container 16a forms at least one refrigeration compartment 18a. In this case, the refrigeration compartment 18a is designed as a freezer compartment. The inner container 18a forms at least one receiving contour 20a for receiving a refrigeration unit 22a (see Figure 10a). Figure 3 ). The household refrigeration appliance 10a forms an insulating space 26a between the outer casing 12a and the at least one inner container 16a.

[0040] The household refrigeration appliance 10a has at least one filling element 28a. The filling element 28a is arranged in the insulation chamber 26a. The filling element 28a is designed to prevent foam accumulation when the insulation chamber 26a is filled with an insulation element 24a (see figure). Figure 4 to prevent this. In the present case, the household refrigeration appliance 10a comprises the filling element 28a and a further filling element 54a. In the present case, the filling element 28a is arranged in a corner region 30a of the insulation space 26a. The further filling element 54a is arranged in another corner region 78a of the insulation space 26a. The further filling element 54a is essentially identical to the filling element 26a, which is why, with regard to the properties of the filling element 54a, reference is made to the description of the filling element 26a below.

[0041] The filling element 28a contains polystyrene. In this case, the filling element 28a is at least substantially composed of polystyrene, specifically expanded polystyrene (EPS).

[0042] Figure 3 Figure 1 shows a schematic partial sectional view of the inner container unit 14a with the receiving contour 20a of the inner container 16a and with the refrigeration unit 22a of the household refrigeration appliance 10a. The receiving contour 20a forms at least one snap-in receptacle 68a. The refrigeration unit 22a has at least one snap-in element 70a. In an assembled state of the household refrigeration appliance 10a, the refrigeration unit 22a is snapped into the snap-in receptacle 68a of the receiving contour 20a by means of the at least one snap-in element 70a and is thus connected to the inner container 16a.

[0043] Figure 4Figure 1 shows a schematic perspective view of the household refrigeration appliance 10a in its assembled state. In the assembled state, the insulation element 24a is arranged in the insulation chamber 26a. The insulation element 24a is made of a thermally insulating polyurethane foam and is foamed in situ within the insulation chamber 26a. The filling element 28a has a higher density than the insulation element 24a. Because the filling element 28a has a higher density than the insulation element 24a, it can be ensured that the filling element 28a withstands the foam pressure during the foaming of the insulation chamber 26a with the insulation element 24a and is not deformed in the process.

[0044] The refrigeration unit 22a has a width 32a. The width 32a is smaller than the width 34a of the refrigeration compartment 18a.

[0045] Figure 5Figure 1 shows the inner container unit 14a with the inner container 16a and another inner container 72a in a schematic perspective view. The household refrigeration appliance device 10a has an adhesive element 36a. The adhesive element 36a is arranged at least partially between the filling element 26a and the inner container 16a and connects them to each other by a material bond. In this case, the adhesive element 26a is designed as an adhesive strip. The filling element 28a has at least one recess 40a through which the insulation element 24a (see Figure 10a) passes. Figure 4The insulating element 24a contacts the receiving contour 20a and the snap-in receptacle 68a of the receiving contour 20a. In this case, the filling element 28a has the recess 40a and a further recess 74a. The further recess 74a of the filling element 28a is offset in a vertical direction 44a from the recess 40a. Through the further recess 74a, the insulating element 24a contacts the receiving contour 20a and, in particular, a further snap-in receptacle (not shown) of the receiving contour 20a.

[0046] Figure 6Figure 1 shows a schematic diagram illustrating a method for manufacturing a household refrigeration appliance 10a, comprising at least one inner container unit 14a arranged within the outer casing 12a, which includes at least one inner container 16a forming at least the refrigeration compartment 18a and at least the receiving contour 20a for receiving the refrigeration unit 22a, and the insulation element 24a, which is preferably foamed in situ and is arranged in the insulation space 26a between the outer casing 12a and the at least one inner container 16a. In the method for manufacturing the household refrigeration appliance 10a, at least one filling element 28a is arranged in the insulation space 26a. The method comprises several process steps. In a first process step 56a, the inner container unit 14a is manufactured by means of a deep-drawing process.In this process, at least one inner container 16a is shaped such that it forms at least one cooling compartment 18a and at least one receiving contour 20a for receiving the refrigeration unit 22a. In the first process step 56a, the outer housing 12a is also manufactured in a sheet metal forming process. Subsequently, in a second process step 58a, the inner container unit 14a is arranged in the outer housing 12a such that the insulation space 26a is formed between the at least one inner container 16a and the outer housing 12a. In a third process step 60a, the at least one filling element 28a is arranged in the insulation space 26a. In the third process step 60a, the filling element 28a is arranged in the corner area 30a and the further filling element 54a in the further corner area 78a of the insulation space 26a and each is connected to an outer surface of the inner container 16a in a materially bonded manner.In a fourth process step 62a, the insulation chamber 26a is filled with foam containing the insulation element 24a. The filling element 28a is therefore positioned in the insulation chamber 26a before the insulation element 24a is inserted into the insulation chamber 26a. Thus, in the fourth process step 62a, foam accumulation in the area of ​​the filling element 28a is prevented.

[0047] In Figure 7 and 8 Two further embodiments of the invention are shown. The following descriptions are essentially limited to the differences between the embodiments, whereby with regard to components, features and functions that remain the same, reference is made to the description of the embodiment of the Figures 1 to 6 Reference can be made to. To distinguish the embodiments, the letter a in the reference numerals of the embodiment is used in the Figures 1 to 6 by the letters b and c in the reference numerals of the exemplary embodiments of the Figure 7and 8 replaced. With regard to identically designated components, especially those with the same reference numerals, reference can generally also be made to the drawings and / or the description of the embodiment of the Figures 1 to 6 be referred.

[0048] Figure 7Figure 1 shows a further embodiment of a household refrigeration device 10b in a schematic representation. The household refrigeration device 10b differs from the household refrigeration device 10a of the previous embodiment essentially with regard to the design of a filling element 28b. The filling element 28b is designed as a vacuum insulation panel 52b. The filling element 28b, designed as a vacuum insulation panel 52b, has a support core 64b. The support core 64b is made of an open-pore evacuated plastic foam. The filling element 28b, designed as a vacuum insulation panel 52b, has a protective cover 66b which hermetically encloses the support core 64b.

[0049] Figure 8Figure 1 shows a further embodiment of a household refrigeration appliance 10c. The household refrigeration appliance 10c has an outer housing 12c and an inner container unit 14c arranged inside the outer housing 12c. The inner container unit 14c has an inner container 16c, which forms at least one refrigeration compartment 18c and a receiving contour 20c for receiving a refrigeration unit (not shown). The inner container unit 14c forms at least one further refrigeration compartment 42c. In this case, the further refrigeration compartment 42c is formed by a further inner container 72c of the inner container unit 14c. The further inner container 72c forms a further receiving contour 80c for receiving a further refrigeration unit (not shown). An insulation space 26c is arranged between the outer housing 12c, the inner container 16c, and the further inner container 72c of the inner container unit 14c.In the assembled state of the household appliance 10c, an in-situ foamed insulation element (not shown) is arranged in the insulation chamber 26c. The household appliance 10c has at least one filling element 28c, which is arranged in the insulation chamber 26c, specifically in a corner region 30c of the insulation chamber 26c. In contrast to the preceding embodiments, the filling element 28c extends in a vertical direction 44c at least partially along an outer surface 46c of the cooling compartment 18c and at least partially along another outer surface 48c of the further cooling compartment 42c.

[0050] The household appliance device 10c has an adhesive element 36c, which is at least partially arranged between the filling element 28c and the outer housing 12c and connects them. In this case, the adhesive element 36c is designed as a screw. The outer housing 12c has a receiving rail 82c, which receives the filling element 28c. In this case, the filling element 28c is screwed to the receiving rail 82c of the outer housing 12c by means of the adhesive element 36c. Alternatively or additionally, it would also be conceivable that the filling element 28c and the outer housing 12c are materially bonded to each other via another adhesive element (not shown), for example, via an adhesive layer.

[0051] The filling element 28c comprises cellulose. In this case, the filling element 28c is made at least substantially of cellulose, specifically honeycomb cardboard. The household refrigeration appliance 10c has a further filling element 54c, which is arranged in a further corner area 78c of the insulation chamber 26c. The further insulation element 54c is also made at least substantially of cellulose, specifically corrugated cardboard, and extends in the vertical direction 44c at least partially along the outer side 46c of the refrigeration compartment 18c and at least partially along the further outer side 48c of the further refrigeration compartment 42c.
