Description

One aspect of the invention relates to a household refrigeration appliance with a housing. The housing has a body and a door. At least one receiving space for food is formed in the body. A further aspect of the invention relates to a method for manufacturing a household refrigeration appliance.

In conventional household refrigeration appliances, it is known that a housing has a body and a door. The housing usually has an outer shell or an outer shell made of sheet metal. This forms vertical side walls and a top wall in one example. In addition, it is common for a household refrigeration appliance to have an inner container. This is a separate plastic component. It is usually made in one piece and can be produced, for example, by deep drawing or injection molding. This inner container delimits an accommodation space with its walls, such as a refrigerated compartment or a freezer compartment.

In conventional household refrigeration appliances, it is necessary for a thermally insulating material to be arranged in an intermediate space between this inner container and the outer housing. This thermally insulating material can usually be an insulating foam. It is also possible for such an insulation material to be bulk material. In these exemplary embodiments it is therefore necessary on the one hand to provide the inner container and the outer housing in order to delimit this intermediate space with the corresponding walls and then to be able to introduce the insulation material in the form of this foam or this bulk material.

In addition, it is also known that vacuum insulation panels, which also represent thermally insulating material, are introduced into such an intermediate space. Such vacuum insulation panels are known, but their design is not stable. Therefore, these walls of the inner container or the outer housing are also required here in order to be able to keep such vacuum insulation panels in their unstable form.

With such known constructions of household refrigeration appliances, a wide variety of individual steps are required for the manufacture and manufacture of these individual components. This means that a very low number of variants is possible both when producing the separate inner container. This is because individual deep-drawing tools or injection molding tools are required for each different design of such a one-piece inner container. The number of variants in conventional household refrigeration appliances is therefore very low simply because of the complexity of producing and providing these respective tools and also with regard to the respective space requirement. The same applies to the production of the outer housing. Therefore, if such variants are provided at all, an enormous amount of production tools and thus a large machine park is required.

The use of vacuum panels in a space between an inner container and an outer housing is, for example, from EP 2 719 981 A1 known. Also is from the WO 1997/012100 A1 the use of vacuum insulation panels in household refrigeration appliances is known. There, these vacuum insulation panels are embedded in other materials. Here, too, they are positioned between an inner container and an outer housing.

It is the object of the present invention to create a household refrigeration appliance and a method in which the creation of variants is made possible in a simpler and more varied manner.

This object is achieved by a household refrigeration appliance and a method according to the independent claims.

One aspect of the invention relates to a household refrigeration appliance with a housing. The housing has a body and a door. At least one receiving space for food is formed in the body.

In one exemplary embodiment of the household refrigeration appliance, the housing is formed by at least one framework-like skeleton structure. The skeleton structure therefore specifies the basic shape and size of the housing, for example the body or the door. The housing also has dimensionally stable or inherently stable, thermally insulating plates with vacuum insulation panels. These plates, which are separate from the skeleton structure, are arranged in free spaces in the skeleton structure. In one exemplary embodiment, this at least one plate is arranged as a visible component and in the exemplary embodiment forms an outside of the housing. In addition to or instead of this, at least one inherently stable and thermally insulating panel as a visible component can form an inside that directly delimits the receiving space. In this new concept of a domestic refrigeration appliance, specific components, namely thermally insulating panels, are thus formed in an inherently stable manner. This means that they do not require any other and separate components to maintain their shape. Even when set up freely, such a panel retains its basic shape. A collapse or a Buckling or buckling is thus excluded with an inherently stable, thermally insulating panel. This is a particular advantage in order to also be able to use such thermally insulating panels in the proposed concept as, in particular, external and/or internal visible components. In the proposed concept of the new type of household refrigeration appliance, not only are such, mechanically very specific, thermally insulating panels used, but as a further consequence they are also individually installed locally on the household refrigeration appliance, so that they are also visible components in this respect. As a result, on the one hand, the number of components can be reduced. Because separate inner walls and/or separate outer walls are then no longer required. This component, which is intended in its primary function as a thermally insulating plate, is then used in a multifunctional manner. Because it then also represents a separate housing part, which is arranged so as to be exposed either to the outside and/or to the inside. This is particularly advantageous in connection with the proposed skeleton structure or the framework structure. This skeletal structure is also particularly inherently stable, so that it remains self-retaining and shape-retaining when erected. Such a mechanically stable skeleton structure is therefore a particularly advantageous carrier system for further components, in particular these specifically thermally insulating panels. As a result, a highly functional and highly versatile, individually configurable system can be provided. On the one hand, these individually formed and mechanically very stable plates can then be arranged directly on the skeleton structure.

A specific half-timbered structure with a kind of facade cladding, which is formed by the thermally insulating, inherently stable panels, is thus made possible. A further particular advantage of such a proposed concept for a household refrigeration appliance can also be seen in the fact that it can be produced without thermal insulation foam, for example without polyurethane foam, as the insulation material. Since in one embodiment only these thermally insulating plates are arranged as insulating material for the housing and are arranged on the skeleton structure, there is no gap between an outer housing and an inner container that would have to be filled with such insulating foam or bulk material for thermal insulation. Such is completely dispensable with this new concept of a household refrigeration appliance. Therefore, the novel concept for this household refrigeration appliance is also designed in such a way that, in particular, such a gap, which would have to be filled with insulating foam or bulk material, is fundamentally no longer present. Because the panels are already thermally insulating components that do not require any additional insulating foam or bulk material in an intermediate space. Since these inherently stable, thermally insulating plates are also each formed with at least one vacuum insulation panel, a special thermal insulation effect is also made possible. Inherently stable, thermally insulating vacuum insulation panels are particularly advantageous for household refrigeration appliances, as explained above. Thanks to their inherent stability, they do not require any additional support components, such as a separate outer housing or an inner container. Therefore, precisely for such components, such a previously customary and known intermediate space between an outer housing and an inner container is completely dispensable. Therefore, such a household refrigerating appliance does not require an additional outer housing and/or an additional and separate inner container in addition to these thermally insulating, inherently stable plates. In one exemplary embodiment, a household refrigeration appliance is therefore formed without an outer housing and/or without an inner container separate therefrom in terms of its housing. The housing is then only formed by the skeleton structure and the thermally insulating panels with vacuum insulation panels. Such a thermally insulating panel can therefore only be formed by an inherently stable vacuum insulation panel. It is also possible for such a thermally insulating panel to have a wall part arranged on it in addition to a vacuum insulation panel. However, this is only to be understood to the effect that such an inherently stable, thermally insulating plate is finished as a component that is prefabricated anyway and also provided as a unit and is then installed as such in the household refrigeration appliance, in particular in the skeleton structure. In this context, a bond can also be provided between a vacuum insulation panel of such a plate and such an additional wall. In particular, a non-destructive non-detachable connection can be provided between the vacuum insulation panel and this additional wall. However, it is also possible for a detachable connection to be provided. For example, this can be realized by an adhesive tape and by a hook-and-eye connection area, such as a so-called hook and loop fastener.

In one exemplary embodiment, the body of the housing is formed by at least one lattice-like skeleton structure that can be erected in an inherently stable manner as the basic framework. The body preferably has dimensionally stable or inherently stable, thermally insulating panels with vacuum insulation panels. These are arranged in free spaces of the skeleton structure, with a Plate as a visible component forms an outside of the body and/or the plate as a visible component forms an inside directly delimiting the receiving space. In one exemplary embodiment, the body then has no separate inner container, as was explained above with regard to the prior art. In one exemplary embodiment, the body then has no outer housing, as was explained above with regard to the prior art.

In one embodiment, the door of the housing has at least one framework-like skeleton structure, and the door has dimensionally stable or inherently stable, thermally insulating panels with vacuum insulation panels that are arranged in free spaces of the separate skeleton structure. As a visible component, a panel forms an outside of the door and/or the panel, as a visible component, forms an inside that directly delimits the receiving space when the door is closed. A door can also be set up particularly advantageously using this new concept. Here, too, it is no longer necessary for the door to be formed by an inner lining made of plastic, which is deep-drawn or injection-molded, for example, and by a separate outer lining, which can be sheet metal, for example. Corresponding doors are also known here from the prior art, in which thermally insulating material, as mentioned above as insulating foam or bulk material, is also introduced into the intermediate space between the outer lining and the inner lining. With the new concept, a door for a household refrigeration appliance can also be completely rebuilt. Such a panel construction alone with a skeleton structure now makes it possible to design very different doors in a very varied manner.

With both the door and the body, this new concept also makes it possible to significantly reduce the thickness between an inner container and an outer housing in a body. In household refrigeration appliances that are conventional in this regard, this thickness between a wall of an inner container and a wall of the outer housing is approximately 12 cm to 13 cm.

In the concept proposed here, a plate with vacuum insulation panels that is thermally insulating and inherently stable in this respect can have a thickness of between 2 cm and 8 cm, in particular between 2 cm and 4 cm. The same also applies to a corresponding structure of a door. This also means that, compared to the prior art, such a wall thickness of a body or a door can be significantly reduced. This also makes it possible that compared to the same size of a conventional household refrigeration appliance, more space is made possible for the volume of the receiving space. On the other hand, it is also possible for the overall size of the household refrigeration appliance to be reduced while the size of an accommodation space remains the same. In this regard alone, a wide variety of variants for the sizes and shapes of such a new type of household refrigeration appliance can be made possible.

In one exemplary embodiment, the skeleton structure has angular, in particular square, frame areas. The frame areas are formed by separate frame parts, in particular straight frame parts. At least one separate, thermally insulating and inherently stable plate is arranged in the free spaces that are bordered or framed by the respective frame areas and is held in a form-fitting manner on the narrow edge of the plate in particular by the respective frame area. As a result, such a plate is also arranged in a mechanically stable manner on the skeleton structure.

Since the frame parts of the skeleton structure can also be easily manufactured and provided in different lengths and sizes in one exemplary embodiment, a diverse individual configuration of the skeleton structure is made possible. As a result, no extensive and diverse tool components are required that would have to be provided. Since such a skeleton structure can also be assembled and set up very easily and quickly with the frame parts provided, this is a further advantage of the proposed concept.

Such a skeleton structure with the scaffolding parts or frame parts described can be constructed individually in a wide variety of ways in terms of height and/or width. Because the frame parts can be put together in a wide variety of ways. In particular, the provision of frame parts of different lengths, which can all be directly connected to one another in a detachable manner, results in a wide variety of possible configurations for a skeleton structure. This results in a wide variety of new dimensions for such a household refrigeration appliance. Because in this context, a very individualized skeletal structure can then be made possible both in depth and in height as well as in width. The configuration option for a household refrigeration appliance is therefore significantly more flexible and variable, even with the basic structure, namely the housing. This means that a household refrigeration appliance can also be configured individually for the customer in the future. It can then be put together by the customer himself and individually adapted to his installation requirements. This also makes it possible for such a household refrigeration appliance to be can be adapted to a wide range of individual installation conditions. Last but not least, this also makes it possible for a household refrigeration appliance of this type to be set up, for example, in a living room and not just in the kitchen or in a cellar. Because this individual configurability of the skeleton structure with the plates that can be provided individually, especially in size, a housing of the household refrigeration appliance can be made possible, which can be set up in a living room not only with regard to the dimensions but also the external visual appearance. Last but not least, this can also make it possible for such a domestic refrigeration appliance to be set up in a living room, for example as a cupboard part or as a sideboard, when viewed from the outside and its external appearance. These specific examples are by no means to be understood as exhaustive. They are only intended to illustrate the diverse expansion options and possible uses as well as installation options that are possible for such a new configuration concept of a household refrigeration appliance. Since the inherently stable, thermally insulating panels can be manufactured and produced completely independently and independently of other components of the household refrigeration appliance, not only in this context, a wide range of individual wishes can be taken into account, especially with regard to the visual appearance. Since with the proposed concept such a plate is positioned as a visible component, namely with respect to the outside of the housing and/or the inside delimiting a receiving space, the most diverse individual design options can also be provided here. A plate then also serves as a decorative part of the household refrigeration appliance.

In one embodiment, the disk includes a shell. The shell has a shell outer part. In particular, the cover also has a cover inner part. Provision can be made for the outer part of the case and/or the inner part of the case to be dimensionally stable. In this way, in particular, external walls of the plate are formed, which at least support the inherent stability of the plate. Shell parts of this type can also be used to provide outer parts of this panel that are stable with respect to impact effects or other mechanical impairments. Thus, novel panels of this type proposed here are also particularly suitable as visible components in order to be used in the household refrigeration appliance or its housing. This is not the case with conventional vacuum insulation panels. These usually have thin foils as casings, in which undesired effects of force already lead to damage and thus to the unsuitability of such a vacuum insulation panel.

In one embodiment, the shell outer and the shell inner are separate walls. In one exemplary embodiment, these are firmly, in particular non-detachably, connected to one another. This also supports this inherent stability or dimensional stability of the panel. Last but not least, this also results in a mechanically stable connection between these two shell parts. In particular, this can also result in mutual support of the shell parts. This further improves the inherent stability of the panel.

In one exemplary embodiment, it can be provided that the outer part of the case differs in material and/or the structure and/or the color and/or the thickness from the inner part of the case. This also enables a very individual configuration of such a plate. Depending on its intended use in the housing, in particular whether it is to be a visible component on the outside of the housing or a visible component on the inside that delimits a receiving space, the respective installation positions can be taken into account in the best possible way. In particular, when the plate is installed or used as a visible component both on the inside and on the outside at the same time, different conditions can be taken into account on the outside than on the inside.

In one embodiment, the outer part of the casing can be formed as a multi-layer composite wall. In another embodiment, the cover part can be formed as a multi-layer composite wall. This means that such a composite wall is made up of at least two layers. These are in particular firmly connected to one another. In particular, they are inseparably connected to one another in a non-destructive manner. The layers can be made of different materials or of the same materials. The layers can be of the same thickness or of different thicknesses. With such a composite wall, the inherent stability of the panel can be configured very individually. In addition, for example, the outer part of the case can meet a higher requirement for impact resistance and scratch resistance than, for example, compared to the inner part of the case. With such a concept, in which such a specific, thermally insulating plate with vacuum insulation panels is to be installed as a visible component of the housing of the household refrigeration appliance, the possible influences on such a visible component can also be better taken into account.

In particular, the thermally insulating, inherently stable panels are prefabricated panels provided, which are then installed as such on the skeleton structure or are installed. The plate is therefore not installed in individual parts step by step on the skeleton structure and is practically only produced by this procedure on the skeleton structure itself. It is already complete before it is installed on the skeleton structure.

In one embodiment, it can be provided that in the mounted state of such inherently stable, thermally insulating panels on the separate skeleton structure, the skeleton structure is covered by these inherently stable, thermally insulating panels on its outside facing away from the receiving space and/or on its inside facing the receiving space, in particular is completely covered. This is another very advantageous embodiment. This is because the skeleton structure can be completely covered from the outside by these plates. A side area or a top area or a rear area of the body is thus formed solely by the dimensions of one or more panels on such a side. The skeleton structure is then covered towards this side. Thus, the skeletal structure does not appear on the outside on this side of the housing. This achieves a very calm and optically uniform appearance. Furthermore, the skeletal structure is also protected. Last but not least, this arrangement of the plates can also improve additional stabilization of the mechanical connection between the skeleton structure and a plate. Because the plate is not only arranged in the free space that is surrounded by a frame area of the skeleton structure, but also in this respect in the main area in which the skeleton structure extends, also protrudes laterally beyond these free spaces and thus then the frame parts from the plate are covered, in this respect a mutual abutment and support of the plate and the skeleton structure is also achieved in these specific lateral areas or surface areas of this skeletal structure. Last but not least, this also enables a very uniform facade appearance of an outside of the housing and/or of a surface area delimiting the receiving space. In this respect, the skeleton structure is then also surrounded or covered by the plates on at least two sides.

In one embodiment, the skeleton structure is formed as a support frame for additional components that are different from these intrinsically stable, thermally insulating panels of the household refrigeration appliance. The skeleton structure is thus used multifunctionally. On the one hand, it determines the basic size of the household refrigeration appliance and/or the basic shape of the household refrigeration appliance, on the other hand it serves as a support for the thermally insulating and inherently stable plates arranged directly on it and then also serves as a support for these additional components. This also enables a mechanically stable connection and precise positioning of these additional components. Because the skeleton structure is a very stable scaffold structure in this regard. In this context, the weight of such additional components can be absorbed without any problems.

Not only in this context can the skeleton structure be formed from frame parts that are made of metal, for example. It is also possible that at least some of the frame parts are made of plastic, for example. Such parts can also be made of a glass fiber reinforced or carbon fiber reinforced plastic. Last but not least, such configurations can also enable a very weight-reduced configuration of a skeleton structure. In one embodiment, such additional components can be diverse. A hinge or a pull-out rail, such as a telescopic pull-out or the like, a magnet, a cable duct, a light shaft or a shelf support on which a shelf sheet can be placed can only be mentioned here as an example.

The frame parts of the skeleton structure can be hollow at least in certain areas. However, they can also be solid components.

In one exemplary embodiment, the skeleton structure has receptacles at at least two different elevations viewed in the elevation direction of the household refrigeration appliance. These are intended for the purpose that at least one thermally insulating plate, in particular with a vacuum insulation panel, can be reversibly and detachably positioned horizontally in the receiving space. In such an embodiment, this thermally insulating and inherently stable plate forms a separating plate with which the entire connected receiving space can be divided into two partial spaces that are isolated from one another. This also makes it possible in a particularly simple manner to form a large number of variants in the division of the receiving space. This is because such an inherently stable and thermally insulating panel, in particular one that has a vacuum insulation panel, can now also be used as a variably positionable partition panel. Last but not least, due to such an embodiment and the inherent stability of such a panel, this dividing panel is also sufficiently stable to be used as a shelf. This then also means that this plate with the vacuum insulation panel itself not only divides the receiving space into two isolated sub-spaces, but also stores stored goods or food receptacles on the top of this dividing plate containers, such as bowls or the like, can be set up. Due to this inherent stability, the corresponding weight of these stored goods can be accommodated without any problems. In this context, too, separate shelves or the like are no longer required precisely for use as a dividing plate. In addition, with this specific plate, which is then used as a separating plate, it is now also easily possible to thermally insulate these two partial spaces with this component alone. This is not possible with conventional shelves. It is thus also possible for individually large partial spaces of the receiving space to be formed by providing these at least two discrete different height positions for this specific partition plate.

In one exemplary embodiment, the domestic refrigeration appliance has a configurable assembly module. This mounting module is a component of the household refrigeration appliance that differs from the inherently stable, thermally insulating panels. The configurable assembly module is therefore present in addition to these specific inherently stable and thermally insulating panels. By providing such a mounting module, further components can be installed in the household refrigeration appliance, namely individually on this mounting module. It is therefore intended to attach further, possibly also required, components for the household refrigeration appliance to this assembly module. Because this is also individually configurable according to the advantageous exemplary embodiment, the flexibility and variant options for this assembly module are also high.

In one embodiment, the assembly module is prefabricated as a pre-assembly module. This means that it is configured individually as a pre-assembly module depending on the domestic refrigeration appliance and is then provided as such, in particular in a completed form. This prefabricated assembly module is then installed as such, in particular as a whole, in the further manufacturing process. In particular, it is made possible in this case for the assembly module to be fastened to the skeleton structure, in particular directly to the skeleton structure. In this connection, too, the skeleton structure serves as an advantageous carrier system, in particular a carrier framework.

It is particularly advantageous that the assembly module has a configurable assembly plate. This mounting plate is intended for the purpose that further additional components of the household refrigeration appliance can be detachably mounted on it, in particular can be mounted directly on it. A mechanically robust module is thus provided in this exemplary embodiment, which specifically has a suitable mounting plate for this purpose. This mounting plate also serves as a separating plate for other additional components. It is particularly advantageous if this mounting plate is not a thermally insulating plate, as was mentioned above and is built into the skeleton structure. In particular, this mounting plate has no vacuum insulation panel. Even if the mounting plate has a thermal insulation effect due to its material configuration and physical conditions, it is fundamentally of a different structure and construction than the above-mentioned thermally insulating and inherently stable plate with a vacuum insulation panel. The primary function of this mounting plate is therefore not a thermal insulation effect, but a mechanical support function for additional components. As a result, it is now also possible with the household refrigeration appliance to provide such an assembly module, in particular an assembly module separate from the skeleton structure, which can accommodate additional components in a mechanically stable and robust manner in addition to the skeleton structure. This also makes it possible for additional components to be advantageously positioned at other points in the housing than on the skeleton structure. By using this configurable assembly module accordingly, these additional components can also be attached in a simplified assembly process. Thus, not only in the basic design of the housing is a diverse and highly flexible modular system that can be assembled in many variants, but also a highly variable and diversely flexible modular principle is realized for this configurable assembly module. This is especially due to the individually configurable mounting plate. This also means that the mounting plate can be assembled as a modular system. Depending on the configuration, a single mounting plate can then also be present here. It is also possible that a mounting plate is made up of several separate sub-mounting plates. In particular, this can depend on which additional components and at which point these additional components are to be attached to the mounting plate. In particular, this configurability of this mounting plate, in particular with regard to its number of sub-mounting plates, also depends on the skeleton structure in one embodiment. In particular, the configuration of such a mounting plate depends on the size and/or shape of the household refrigeration appliance to be configured. In the assembled state, the partial mounting plates are arranged in a common plane.

It is particularly advantageous that this assembly module can be detached at least predominantly, in particular in all individual parts, with non-destructive means ren connections is established. In this way, such an assembly module can be set up quickly and easily on the one hand, and dismantled again quickly and easily on the other hand. This means that individual parts of this assembly module can be exchanged individually. A particular advantage of this configurable assembly module can be seen in the fact that at the end of the life cycle of such a household refrigeration appliance it can simply be finally dismantled and the recyclability of the household refrigeration appliance is therefore particularly high and therefore very advantageous. This advantageous recycling concept also applies to the entire household refrigeration appliance. In this context, the housing can also be easily dismantled at the end of the household refrigeration appliance's life cycle. This is because the skeleton structure with its frame parts also preferably has non-destructively detachable connections. This means that the skeleton structure can also be easily dismantled again.

In one embodiment, the mounting plate with the additional components is formed as a pre-assembly module, which can be dismantled in particular, and which is individually configured depending on the device type in terms of size and/or type and/or number of additional components.

In particular, in one exemplary embodiment, the mounting plate is formed from a plurality of individual plates or partial mounting plates connected to one another, so that the height and/or width of the mounting plate can be configured individually.

In one exemplary embodiment, the mounting plate is arranged in front of a thermally insulating, inherently stable plate in the receiving space of the household refrigeration appliance, viewed in the depth direction. This thermally insulating plate represents a rear wall of the body. The mounting plate is therefore designed in such an embodiment as a suspension arranged in front of this rear wall. In particular, as a result, the mounting plate is positioned very specifically locally, so that very specific additional components can be individually installed locally in the receiving space. These additional components can be, for example, a fan and/or an air duct and/or a drainage channel and/or a mounting strip or the like.

In one exemplary embodiment, viewed in the depth direction, a free space is formed between the mounting plate and the thermally insulating, inherently stable plate. In the depth direction, the mounting plate is therefore arranged at a distance from this thermally insulating plate forming the rear wall of the body. This free space can also be used as a technical room. This means that additional components of the household refrigeration appliance can be arranged in the free space. In particular, further technical components of the household refrigeration appliance are arranged in this free space.

In general, it can be said that the invention with this diverse, individually configurable structure, in particular the skeleton structure and/or the thermally insulating, inherently stable panels and/or the assembly module, can be used to produce prefabricated individual systems of the household refrigeration appliance, which are each initially produced or can be set up and then assembled in a modular design. The modular principle of such a household refrigeration appliance is therefore particularly advantageous and excessive. Therefore, unlike in today's conventional manufacturing processes, extensive and large specific tools are no longer required. This applies in particular in comparison to the manufacturing processes for inner containers and/or outer housings. Since the thermally insulating, inherently stable panels also have an insulation value that is very high compared to other insulation materials used, advantages can also be achieved here. In particular, these thermally insulating, inherently stable panels are designed so that whenever their insulation value is the same as a conventional structure with an inner container, an intermediate space filled with thermal material and an outer housing, the thickness is reduced by at least 20%, in particular by a value between 20 % and 130% thinner than a conventional structure in this regard. On the other hand, it can also be said that with a correspondingly thick structure of such a thermally insulating, inherently stable plate, the insulation value can be significantly increased compared to conventional technology.

In one embodiment, the thickness of a thermally insulating, inherently stable panel is between 2 cm and 7 cm, in particular between 2 cm and 4 cm, in particular between 2 cm and 3 cm.

With a correspondingly modular structure of a door of the housing, the skeleton structure can be formed from plate-like, in particular board-like, frame parts. These are larger than the frame parts of the skeletal structure of a body, particularly in the depth direction of the household refrigeration appliance. As a result, a particularly stable door is designed and also provided with a corresponding thickness. In particular, these board-like frame parts are also suitable for the special stability of the skeleton structure of the door. In particular, such a structure can also enable a particularly stable door, which can also accommodate many additional components. In particular it is It also enables a front-side, thermally insulating and inherently stable plate to be designed in one piece and thus has no interface whatsoever on its outside. As a result, a very calm and optically advantageous appearance can also be generated. There are then no abutting interfaces between two separate such plates, which can also be provided and then bear directly against one another. The same can be prefabricated with the vertical outer sides and/or the top of a body of the housing of the household refrigeration appliance. Such one-piece, thermally insulating and inherently stable plates are also preferably provided there.

A further aspect of the invention relates to a method for manufacturing a household refrigeration appliance according to the aspect mentioned above or an advantageous exemplary embodiment thereof. In the method, in one exemplary embodiment, at least two different variants of the household refrigeration appliance are or can be configured. This in particular to the effect that the skeleton structure is optionally configured for the first or at least the second variant, depending on the device type, and/or an assembly module is optionally configured for the first and/or the second variant, depending on the device type, and/or the size and/or the number of inherently stable , Thermally insulating panels are optionally configured for the first or at least the second variant. This applies in particular to the corresponding size design and provision as well as prefabrication of the corresponding components mentioned, in order to be able to provide them as respective pre-assembly modules and then to be able to assemble them afterwards.

In an advantageous exemplary embodiment, a skeleton structure is preassembled in the method for manufacturing a household refrigeration appliance. During the production process, this skeleton structure is therefore initially built up independently of the production of intrinsically stable, thermally insulating panels and/or a configurable assembly module. In such a method, the manufacturing process of this skeleton structure therefore represents a manufacturing process independent of the other components. In an advantageous embodiment, the skeleton structure is therefore produced at least partially, in particular completely, as a separate module or as a separate unit of the household refrigeration appliance. In particular, this skeleton structure is completely prefabricated and then provided as a separate prefabrication unit. In addition to or instead of this, in one exemplary embodiment, the assembly module can be implemented as an independent pre-assembly module independently of the skeleton structure and the provision of the inherently stable, thermally insulating panels. This pre-assembly module is therefore also completely manufactured and made available for further processing or further installation in the household refrigeration appliance.

Therefore, it is provided in an advantageous embodiment that central components of the household refrigeration appliance, namely the skeleton structure on the one hand, the inherently stable, thermally insulating panels on the other hand and in an advantageous embodiment the assembly module as a pre-assembly module are first manufactured independently of one another, in particular up to their finished final state, and then be provided with each other for further, merging shoring. The pre-assembly module and/or the inherently stable, thermally insulating panels are then arranged on the skeleton structure.

Such a manufacturing process for a domestic refrigeration appliance with a related modular concept of individual units enables a particularly advantageous modular principle for producing the entire domestic refrigeration appliance. Processes can be improved in parallel in this context. In addition, these units can be produced easily and independently of one another in individual production processes. They can then also be provided logistically better as separate units and then used individually for further installation. In particular, extensive and complex manufacturing steps, as are the case with conventional household refrigeration appliances, can be avoided in this context. The standardization of processes and thus also the simplification of the production process are therefore significantly increased. It is therefore also possible to first individually prefabricate structurally more complex units and then to preconfigure them for further installation or for assembly with the other units and then to assemble them. A faster manufacturing process can also be achieved as a result.

In 1 an embodiment of a household refrigeration appliance 1 is shown in an exploded view. The household refrigeration appliance 1 is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator or a freezer or a fridge-freezer combination appliance.

The domestic refrigeration appliance 1 has a housing 2 . This is in 1 shown in an exploded view. In one exemplary embodiment, this housing 2 has a body 3 . In addition, the household refrigeration appliance 1 has a door 4 that is separate from the body 3 . The housing 2 can have a door 4 . However, it can also have several doors. In the exemplary embodiment, a household refrigeration appliance 1 is shown which, in the assembled state and in the configured end configuration, has two vertically pivotable doors 4a and 4b. In addition, another front door 4c is provided, for example, in the household refrigeration appliance 1, which can be pivoted about a horizontal axis. In the exemplary embodiment, a further front door 4b is provided. This is formed here as a drawer that can be displaced linearly in the depth direction (z-direction). The embodiment according to 1 and 2 is only to be understood as an example. Of course, the invention also includes domestic refrigeration appliances that only have one door. This can be a door which can be pivoted relative to the body 3 about an axis oriented in the vertical direction (y-direction). A household refrigeration appliance that only has the doors 4a and 4b is also possible. It is also possible for a household refrigeration appliance to have a door 4a and/or 4b, for example, and also to have only the door 4c or only the door 4d, for example. In this context, the most diverse configurations are possible with regard to the number and type of doors, all of which are encompassed by the idea of the invention. The doors 4, 4a, 4b, 4c, 4d are, in particular, front-side visible components of the household refrigeration appliance 1. They represent components of the shell of the household refrigeration appliance 1.

The housing 2, in particular the body 3, has at least one storage space for food. This receiving space can be a refrigerator compartment or freezer compartment. So it includes household refrigeration appliances that only have such a receiving space. However, exemplary embodiments are also possible in which several, in particular separate, receiving spaces are provided in a single household refrigeration appliance 1 . in the in 1 shown embodiment, three receiving spaces 5a, 5b and 5c are provided. In this context, in the assembled state, the receiving space 5a, as shown in 2 can be seen, closed by the doors 4a and 4b. The other receiving space 5b can be closed by the door 4c. The further receiving space 5c, which is exemplary here, can be closed by the door 4d.

The housing 2 has at least a framework-like skeleton structure. This skeleton construction is inherently stable. The housing 2 also has dimensionally stable or inherently stable, thermally insulating plates with vacuum insulation panels. Each plate thus has at least one vacuum insulation panel. Viewed as a whole, the panels are dimensionally stable and can be prefabricated and provided in individual sizes and configurations. In the exemplary embodiment, the body 3 has its own skeleton structure 6 . This is formed in this context as a framework from several frame parts. Merely as an example and for the sake of clarity, only some of the frame parts 6a are provided with a corresponding reference number. This skeleton structure 6 has free spaces 7 which are delimited circumferentially by the respective frame parts 6a. Here, too, for the sake of clarity, only some of these free spaces 7 are provided with the corresponding reference numbers. The skeleton structure 6 is intended to accommodate the separate inherently stable and thermally insulating plates with the vacuum insulation panels. For this purpose, in the example in 1 a plate 8, a plate 9 and a plate 10 are shown. These panels 8 to 10 are such inherently stable, thermally insulating panels, each with at least one vacuum insulation panel. These plates 8 to 10 are arranged directly on the skeleton structure 6 in the assembled state. In the example shown here, it is provided that the panels 8 and 9 represent side walls, the panel 10 represents a ceiling wall and the other intrinsically stable, thermally insulating panel with at least one vacuum insulation panel represents a floor wall. In addition, this body 3 has an in 1 Not recognizable, further intrinsically stable, thermally insulating plate with at least one vacuum insulation panel, which forms a rear wall of the body 3. In one exemplary embodiment, it is provided that these plates 8 to 11 are arranged on the skeleton structure 6 in such a way that they cover outwardly facing outer sides 6b of the frame parts 6a to the outside. This applies in particular to all panels 8 to 11, so that in such an embodiment the skeleton structure 6 can no longer be seen from the outside and is covered by the respective panels 8 to 11. In one exemplary embodiment, the panels 8 to 11 are arranged as visible components and their outer sides also form a visible outer side of the body 3. This means that these panels 8 to 11, each of which are self-contained and prefabricated, are also those components which, so to speak, simulate the side form body parts that are exposed at the top, bottom and rear. These panels 8 to 11 themselves are therefore both body delimiting elements and thermally insulating elements. They are therefore multifunctional in this respect, each in the form of their own, in particular non-destructive, non-detachable units.

It is possible that the plates 8 to 11 are each arranged directly on the skeleton structure 6 by non-destructively detachable connections and thus connections that can be reversibly produced and detachable again. This is particularly advantageous in that the household refrigeration appliance 1 can be easily dismantled and disposed of at the end of its life cycle. The recyclability of individual components is therefore very high with such a concept for a household refrigeration appliance.

In another exemplary embodiment, provision can also be made for additional, inherently stable, thermally insulating plates 12 and 13 to be provided with vacuum insulation panels. These can be present in addition to the plates 8 and 9 in the exemplary embodiment. You can be designed with a lower height in this regard. In particular, the are provided in one embodiment, the side areas of to limit lower receiving spaces 5b and 5c laterally.

In addition, it is possible that a further thermally insulating plate 14 is provided in one exemplary embodiment. This can also be an inherently stable, thermally insulating plate with at least one vacuum insulation panel. This plate 14 is arranged non-destructively detachable in one embodiment. In particular, it is also attached directly to the skeletal structure 6 . This plate 14 can be used to achieve thermal insulation between the receiving space 5a and the further receiving space 5b.

In another exemplary embodiment, it is also possible for the skeleton structure 6 to have receptacles at least at a specific altitude in the altitude at which the accommodation space 5a extends. An inherently stable, thermally insulating plate with at least one vacuum insulation panel can be used as intended on these recordings. It can then in turn be removed in a non-destructive, detachable manner. In one exemplary embodiment of the domestic refrigeration appliance 1, this means that the continuous receiving space 5a can also be divided at least temporarily into two separate partial receiving spaces. These are then also preferably thermally insulated from one another by this further plate. Such a plate can then additionally serve as a shelf, in particular because of its inherent stability.

In another exemplary embodiment, the plates 8 to 11 can also be arranged in such a way that, as visible components, they form an inner side directly delimiting the receiving space 5a and/or 5b and/or 5c. In such an embodiment, these panels 8 to 11 are then visible components towards the inside.

In a further exemplary embodiment, the plates 8 to 11 can be visible components both to the outside and to the receiving spaces 5a and/or 5b and/or 5c. If the panels 12 and 13 are also present, these components can be seen towards the receiving spaces 5b and 5c.

In the exemplary embodiment shown here, in particular, the side panels 8 and 9 are formed over the entire height of the skeleton structure 6 as one piece. It is also possible that several separate, inherently stable, thermally insulating plates, each with vacuum insulation panels, are arranged over this height. These are then arranged directly adjacent to one another.

With these panels 8 to 11 and/or the panels 12 and 13, a facade structure for the body 3 can thus also be created.

In one embodiment, the door 4 has a skeletal structure 15 . In addition, the door 4 has at least one inherently stable, thermally insulating plate 16 with at least one vacuum insulation panel. It is also possible that in another exemplary embodiment, in which the doors 4a, 4b, 4c and 4d are present, individual separate inherently stable, thermally insulating plates 16a, 16b, 16c and 16d are provided, each with a vacuum insulation panel. In the case of the door 4 or the doors 4a to 4d, it can also be provided that the skeleton structure 15 is formed as a framework or in the form of a framework, as is shown in 1 and 2 is shown. In the exemplary embodiment, the doors 4a to 4d are each formed by a single, quadrangular frame made of specific frame parts. Frame parts 17, 18, 19 and 20 are shown here merely as an example. These frame parts 17 to 20 form a skeleton structure for the door 4a in the illustrated embodiment. For the sake of clarity, the four other frame parts for the other skeleton structures of the doors 4b, 4c and 4d are no longer provided with a reference number.

As in 1 as can be seen, one embodiment provides that these frame parts 17 to 20 are formed as board-like frame parts. They are dimensioned larger in the depth direction than the frame parts 6a of the skeletal structure 6 of the body 3. As a result, the door 4, in particular the doors 4a and 4b as well as 4c and 4d, can be formed with a greater depth. In particular, this makes it possible for a larger volume space 21, as shown in 2 is shown using the example of the door 4b, can be generated towards the receiving space 5a. As a result, food receptacles, such as door racks 22, can also be accommodated there. In particular, it can also be provided in this context that such a frame part 17 to 20 extends in the depth direction at least 50%, in particular at least 80%, in particular at least 100% over the depth of such a door rack 22. this is in 2 shown as an example.

It is also possible that a skeleton structure 6 and/or 15 is constructed from frame parts that are hollow at least in certain areas. In such an embodiment, these cavities of the at least some frame parts can be filled with thermally insulating material. A frame part can be made of metal or plastic, for example.

It is also possible that at least one frame part, at least in some areas, also as eigensta Bile, thermally insulating plate, in particular with at least one vacuum insulation panel is formed.

the inside 1 shown exemplary basic structure of a household refrigeration appliance 1 brings with it several significant advantages, as have already been extensively explained above. In particular, it is possible in this context to fulfill the most varied and flexible individual configurations of a domestic refrigeration appliance 1 . Since the skeletal structures 6 and 15 can be configured very individually, since the respective frame parts of the skeletal structure 6 and/or 15 can be manufactured and provided very individually, a significantly greater variability for the design of a household refrigeration appliance 1 can now be achieved in terms of size and shape. The same also applies to the possibility of individual production and configuration of the inherently stable, thermally insulating panels.

In a further exemplary embodiment, it can be provided that the domestic refrigeration appliance 1 has a configurable assembly module 23 . This assembly module 23 is formed in addition to and separately from these intrinsically stable, thermally insulating panels, each with at least one vacuum insulation panel. This configurable assembly module 23 can therefore also be constructed in a modular manner, as has already been explained for the skeleton structures 6 and 15 and the thermally insulating and inherently stable plates 8 to 14 and 16a to 16d, 25. Therefore, in addition to the skeleton structures 6, 15 and the thermally insulating and inherently stable panels 8 to 14, 16, 16a to 16d, 25, another unit of the household refrigeration appliance 1 can also be individually prefabricated. Because such a configurable assembly module 23 can then also be manufactured independently of the other components as a separate pre-assembly module. This can then already be made available for further installation, in particular on the skeleton structure 6 . It is also particularly advantageous in this connection that this configurable assembly module 23 can also be reversibly dismantled. This assembly module 23 can therefore also be easily separated from the skeletal structure 6 at the end of the life cycle of the household refrigeration appliance 1, on the one hand, and easily dismantled on the other hand. This also significantly increases the ability to disassemble and recycle components of the household refrigeration appliance 1 .

This configurable mounting module 23 is intended to allow additional components of the household refrigeration appliance 1 to be detachably mounted directly on it. In particular, this configurable assembly module 23 has a configurable assembly plate 24 . At this, the additional components of the household refrigeration appliance 1 can be detachably mounted. In particular, the mounting plate 24 can be constructed in a wide variety of individual ways in terms of size and/or shape. Only a single mounting plate 24 can be provided. In another exemplary embodiment, however, the mounting plate 24 can also be constructed from a plurality of individual mounting sub-plates. This also allows individual sizes and shapes of the mounting plate to be specifically configured. The individual installation of additional components on the mounting plate can also be carried out more flexibly and variably as a result. The mounting plate 24 is oriented vertically. Even if several subassembly plates are provided, these are arranged in particular in one plane with respect to one another.

In one exemplary embodiment, the mounting plate 24 is arranged in at least one of the receiving spaces 5a and/or 5b and/or 5c, and viewed in the depth direction of the household refrigeration appliance 1, this mounting plate 24 can be used in particular as a suspension in front of a thermally insulating, inherently stable plate, which then forms a rear wall of the body 3 represents, be arranged. A blower and/or a drainage channel and/or a retaining strip and/or an air duct can be installed directly on this mounting plate 24 as additional components. Here, too, an individual configuration is then possible with regard to the structure of this assembly module 23 . In addition, a floor assembly can also be provided, which can be part of the configurable assembly module 23 . Components of the refrigeration circuit of the household refrigeration appliance 1 can be arranged in this floor pan. In one exemplary embodiment, this floor assembly can then also be connected directly to the configurable mounting plate 24 .

In one embodiment, the thermally insulating and inherently stable panels mentioned can have a shell that has a shell outer part and a shell inner part. Provision can be made for an outer part of the case and/or an inner part of the case to be dimensionally stable. In this context, they form the boundary walls on the visible side of the panel. It is also possible for an outer part of the case and an inner part of the case to be separate walls which are connected to one another in a fixed, in particular non-detachable manner. It can be provided that the material and/or the structuring on the outside and/or the color and/or the thickness of an outer part of the case differ from the inner part of the case. An outer part of the casing and/or an inner part of the casing can be formed as a multi-layer composite, in particular as a multi-layer composite wall. It is also possible for a thermally insulating, inherently stable plate with a vacuum insulation panel to be transparent at least in certain areas. For this purpose, an outer part of the case and/or an inner part of the case can be transparent. It is possible in this context also that an outer part of the case and/or an inner part of the case are made of glass. Glasses of this type can also be colored individually.

Other material configurations for an outer casing part and/or an inner casing part are also possible. In this context, such parts can also be made of plastic or metal or the like. What is essential is that such an inherently stable, thermally insulating panel is provided with a vacuum insulation panel as a prefabricated panel and is installed as such on the skeleton structure 6 and/or 15 .

In one exemplary embodiment, it is possible for additional components of the household refrigeration appliance 1 to be arranged directly on the skeletal structure 6 and/or the skeletal structure 15 . Such additional components can be, for example, a hinge, a pull-out rail, a magnet, a cable duct, a light well or a shelf support. These examples of additional components are not to be understood as exhaustive.

In 3 an exemplary embodiment of a domestic refrigeration appliance 1 is shown in a perspective partial representation. Another inherently stable, thermally insulating plate 25 with a vacuum insulation panel is also shown here, which forms a rear wall of the body 3 here. This plate 25 is also arranged on the outside as a visible component. As can also be seen, the mounting plate 24 is arranged directly on the skeleton structure 6 . Here, too, a mechanically detachable connection is provided in particular. In this regard, it can be solved non-destructively.

In the embodiment in FIG 3 it can be seen that a free space 26 is formed between this plate 25 and the mounting plate 24 . This can be formed as a technical room. This means that further functional components of the household refrigeration appliance 1 can be arranged therein.

In 4 an embodiment of a configurable assembly module 23 is shown in an exploded view. In this exemplary embodiment, the mounting plate 24 is formed from three individual partial mounting plates or from connected individual plates. However, this is only to be understood as an example, and the mounting plate 24 can also be formed from more or fewer individual plates. Exemplary additional components are shown here in the form of fans 27 and 28 and 29 . These can be installed directly on the mounting part plates of the mounting plate 24, in particular on the respective cutouts 24a.

Other possible additional components can be strips 30, which are vertical side strips here and in the assembled state of the configurable assembly module 23, as shown in 5 is shown, the mounting plates 24 enclose the edges. In particular, as a result, the assembly can be carried out directly on the skeleton structure 6 in a simple and mechanically more stable manner. These lateral strips 30 can thus also be mounting strips.

In a further exemplary embodiment, further additional components can be air ducts 31 . These can be part of an air duct system in the household refrigeration appliance 1, with which cold air can be circulated. In particular, this cold air can then also be in specific receiving spaces 5a, 5b and 5c. In particular, these air ducts 31 can be part of a no-frost unit if the household refrigeration appliance 1 is a no-frost household refrigeration appliance.

Horizontal strips 32 can be further exemplary embodiments for additional components. In one exemplary embodiment, these can also have drainage channels integrally. In this way, for example, condensation water can be drained off in a targeted manner. In 5 the assembled state of the configurable mounting module 23 is shown in this context. The individual configuration option is based on the illustrations in 4 and 5 to recognize. In this way, such a prefabricated unit in the form of the preassembly module, which is the configurable assembly module 23, can be constructed and configured in a simple and highly flexible manner.

In 5 an exemplary embodiment of an underbody 33 already mentioned above is also shown. In one exemplary embodiment, this can be a component of the prefabricated assembly module 23 .

In 6 is this configurable assembly module 23 in a 5 shown from different perspectives, here from behind.

In 7 an exemplary embodiment of an intermediate assembly state for the household refrigeration appliance 1 is shown. It is shown here that an individually configured skeleton structure 6 is already prefabricated and provided for one of several possible variants of a household refrigeration appliance 1 . Furthermore, a mounting module 23, as for example 4 until 6 was explained, prefabricated specifically for this variant of the household refrigeration appliance 1 and provided as a pre-assembly module. In 7 then the production-related fused state between the skeleton structure 6 and the configured assembly module 23 is already shown. This assembly module 23 is in 7 already arranged in the skeleton structure 6 and with this installed, in particular arranged firmly on it. In particular, the mechanical connections between the skeleton structure 6 and the assembly module 23 can be detached without being destroyed. In the further assembly process, the prefabricated, inherently stable, thermally insulating panels can then be fastened in the free spaces 7 of the skeleton structure 6 .
