State of the art

[0001] The invention relates to a household appliance device according to the preamble of claim 1, a household appliance according to claim 8 and a method for manufacturing and / or adapting a household appliance device according to the preamble of claim 9.

[0002] It is already known from the publication DE 10 2010 029 577 A1 to apply a protective film to a facing part of a household appliance, namely a dishwasher, by means of hot stamping.

[0003] From CN 110 682 517 A, a perfumed inner container of a refrigeration appliance is known, the manufacture of which comprises hot stamping of an ABS or HIPS sheet and subsequent blister forming.

[0004] The object of the invention is, in particular, to provide a generic device with improved comfort characteristics. This object is achieved according to the invention by the features of claims 1, 8, and 9, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention

[0005] The invention relates to a household appliance device, in particular a household refrigeration appliance device, with an inner liner that at least partially limits a usable space.

[0006] It is proposed that the household appliance device has a surface element which, in an assembled state, is at least materially bonded to at least one part of the inner liner facing the usable space.

[0007] Such a design can advantageously improve comfort, particularly user comfort. Furthermore, a surface element can provide a surface finish for at least a portion of the inner liner. In particular, the visual appearance of the inner liner can be at least partially altered and / or adapted. The surface element can potentially be connected to the inner liner for decorative and / or functional purposes, whereby at least the portion of the inner liner can be advantageously protected from contamination and / or damage, especially scratching, when the surface element is installed.Furthermore, user comfort can be enhanced by allowing the inner liner to be decorated, particularly individually, using the surface element. This could include lettering, shapes, color, or a visually appealing material layer, such as a glossy metallic layer. The inner liner, specifically the side facing the user's space, can be made more visually appealing by means of the surface element. Additionally, the user and / or an installer may be able to choose from several surface elements, allowing for more individualized and flexible design and / or manufacturing of a household appliance.By means of a material-bonded connection between the surface element and the inner liner, additional fastening elements, for example for force-fit and / or form-fit connections, can preferably be dispensed with. This reduces costs, especially manufacturing and / or assembly costs, as well as effort, particularly manufacturing and / or assembly effort.

[0008] The household appliance device could be, for example, a cooking appliance device, in particular an oven device and / or a microwave device and / or a grill device, a household cleaning appliance device, for example a dishwasher device and / or a washing machine device and / or a dryer device, and preferably a household refrigeration appliance device, for example a refrigerator and / or freezer device. In an assembled state, the household appliance device preferably forms a subassembly of a household appliance, in particular a large household appliance and preferably a household refrigeration appliance. However, it would also be conceivable for the household appliance device to comprise the entire household appliance, in particular the entire household refrigeration appliance. The household appliance and / or the household appliance device is intended, in particular, for use in a household.The household appliance could be a large household appliance, in particular a large household refrigeration appliance, for example a chest freezer, and advantageously a refrigerator and / or freezer, and / or a cooking appliance, for example an oven and / or a microwave and / or a grill, and / or a household cleaning appliance, for example a dishwasher and / or washing machine and / or a dryer. Alternatively, it would be conceivable that the household appliance device constitutes a kit for assembling at least part of the household appliance. The kit could, for example, be intended for manufacturing at least part of the household appliance. The household appliance device is particularly preferably intended for assembling, and in particular completing, the inner liner, wherein the household appliance device, in its assembled state, preferably provides a finished, and in particular fully functional, inner liner for the household appliance.

[0009] Advantageously, the household appliance and / or the appliance itself is designed for storing goods within its usable space. The stored goods are, in particular, any type of goods, preferably arranged and / or to be arranged within the appliance, especially consumer goods and / or, advantageously, consumables, preferably foodstuffs. Alternatively, the stored goods could also be at least one cosmetic and / or medical item. The household refrigeration appliance is particularly advantageously designed to cool the stored goods, especially refrigerated goods such as beverages, meat, fish, milk, and / or dairy products, within its usable space in at least one operating state, particularly to extend the shelf life of the stored goods. The usable space could be divided into several sub-spaces, which, for example, could be cooled to different temperatures in at least one operating state.The usable space, or at least a partial usable space, could form a refrigerator compartment or a freezer compartment of the household refrigeration appliance.

[0010] Advantageously, the inner liner is designed to at least partially limit the usable space. In particular, the inner liner limits the usable space on at least one side. The inner liner is preferably a housing, especially a plastic housing, that limits the usable space on at least three, advantageously at least five, and preferably six sides. This housing could include an inner housing box, which could be, in particular, trough-shaped and / or box-shaped. The inner liner especially includes an inner housing cover. The inner liner could be closable on at least one side by the inner housing cover.

[0011] Advantageously, the inner liner has a side facing the usable space and / or a side facing away from the usable space. The partial section extends along the side of the inner liner facing the usable space. The partial section could extend at least partially or completely along a wall of the inner liner. Preferably, in the assembled state, the wall forms a side of the inner liner, in particular a side of the inner liner facing the usable space and defining the usable space. The partial section could extend at least 5%, advantageously at least 20%, preferably at least 50%, and particularly preferably at least 90% along at least the wall. Alternatively, the partial section could also extend over at least two walls of the inner liner, in particular the first wall and at least one other wall of the inner liner.It is conceivable that the affected area extends over at least one edge region of the inner liner, particularly where the wall and at least the outermost wall are connected. It is possible that the affected area could extend over the edge region and at least one other edge region of the inner liner.

[0012] Advantageously, the edge region is a convex surface area along a path length, connecting two at least substantially straight surfaces, in particular the inner wall and the outer wall of the inner liner. Preferably, the edge region has a greater curvature along the path length between at least two defined points, which are preferably less than 15 mm apart, than at least one of the two walls over a correspondingly long path length. Advantageously, the curvature is at least 30°, more advantageously at least 60°, and preferably at least 80°. Particularly preferably, the curvature of the edge region is at least substantially perpendicular, wherein the angle between the inner wall and at least the outer wall deviates from a right angle by at most 5°, more advantageously by at most 2°, and most preferably by at most 1°.

[0013] The inner liner could consist at least partially, largely, or entirely of metal, for example, aluminum, and / or a mineral, for example, glass, and / or preferably of a plastic and / or a composite material. The term "largely" shall be understood to mean, for example, at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85%, and particularly advantageously at most 95% of a volume and / or mass fraction. The inner liner can be formed at least partially and preferably entirely in one piece.The term "one-piece" is to be understood as at least materially bonded, for example by an adhesive bonding process, a welding process, an injection molding process, and / or another process that would appear appropriate to a person skilled in the art, and / or formed in one piece, such as by production using a single- or multi-component injection molding process and / or by production from a single casting and / or by a stamping process from a single blank. Advantageously, "one-piece" is also to be understood as "one-part." "One-piece" is to be understood in particular as formed in one piece. Preferably, this single piece is produced from a single blank, a compound, and / or a casting, in particular by a single- and / or multi-component injection molding process.The inner liner could, for example, be manufactured at least partially and / or to a large extent by means of a deep-drawing process, a 3D printing process, or a sheet metal bending process. Preferably, the inner liner and, in particular, all inner housing components, advantageously the inner housing box and the inner housing cover, are manufactured to a large extent, preferably completely, by means of an injection molding process or by thermoforming.

[0014] In its assembled state, the surface element only partially defines the usable space. Specifically, in its assembled state, the surface element is directly connected, without any intervening components, to the portion facing the usable space, at least by a material bond. It is conceivable that, in its assembled state, the surface element is connected to at least 30%, advantageously at least 50%, preferably at least 70% of the inner liner, and in particular that the portion facing the usable space comprises at least 30%, advantageously at least 50%, preferably at least 70%, and most preferably at least 80% of the inner liner, especially the side of the inner liner facing the usable space. The surface element could consist at least partially, largely, or entirely of metal, for example, aluminum or gold, and / or a mineral, for example, glass, and / or of a plastic and / or a composite material.

[0015] The term "intended" here and in the following refers to specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function means that the object fulfills and / or performs this specific function in at least one application and / or operating state. Furthermore, it is proposed that the surface element be designed as a coating. This can increase comfort and efficiency with regard to product, work, manufacturing, and / or cost efficiency. In addition, a surface element designed as a coating can provide a particularly comfortable surface finish for at least a portion of an inner liner.

[0016] In a method for manufacturing and / or adapting the household appliance device, the relevant section is coated. It is conceivable that, in the assembled state, 30%, advantageously 50%, preferably 70% of the inner liner, specifically the side facing the usable space, is coated. The coating can be a thin layer, a thick layer, or several interconnected layers. A thin layer, particularly a thin film, is a layer of solid materials in the micro- or nanometer range. The thin layer can have a thickness of at most 100 µm, particularly at most 10 µm, advantageously at most 100 nm, and preferably at most 10 nm. In the method for manufacturing and / or adapting the household appliance device, the thin layer could be produced or deposited onto at least the relevant section, for example, by sputtering or molecular beam epitaxy (MBE).The thick layer could be a layer with a thickness of at least 0.5 mm, advantageously at least 2 mm, preferably at least 10 mm and most preferably at most 5 cm.

[0017] Furthermore, it is proposed that the household appliance have a housing which incorporates the inner liner. This would further enhance user comfort by allowing the housing to be at least partially customized and its surface to be finished, decorated, and / or protected.

[0018] Additionally, the device housing could have an outer casing which, particularly in the assembled state, at least partially surrounds the inner liner. The outer casing could form a visible surface. Advantageously, the visible surface defines a surface of the device housing facing away from the usable space and another facing outwards, for example, towards the user. In the assembled state, the device housing can at least partially define the usable space. The inner liner could be at least partially connected to the outer casing, and in particular fixed to it. It would be conceivable that, in the assembled state, at least one insulating element, in particular a thermal insulation element, of the household appliance is arranged between the inner liner and the outer casing. The thermal insulation element is preferably a component designed to prevent heat flow as much as possible.In particular, the thermal insulation element is made at least largely of a plastic, preferably a foam, preferably a rigid foam (EPS and / or PU), for example, of in-situ foam or advantageously as a rigid foam board. In its assembled state, the thermal insulation element is advantageously designed to provide at least thermal insulation to the usable space. It is also possible that, in its assembled state, the surface element may be at least partially bonded to the outer casing. It would be conceivable for the surface element to form at least part of the outer visible surface.

[0019] In an alternative embodiment of the invention, it is proposed that the household appliance device has a door incorporating the inner liner. This further enhances user comfort. Furthermore, a door can be provided that can be at least partially customized and whose surface can be finished, decorated, and / or protected.

[0020] The appliance door, which is pivotally mounted on at least one axis of rotation, could be arranged on the appliance housing, with the appliance door preferably being hinged to the appliance housing in the mounted state. In particular, the appliance door is rotatable about at least the axis of rotation for opening and / or closing. It would be conceivable that at least one hinge of the appliance device, for example a strap and / or a pivot, is arranged on the appliance housing, by means of which the appliance door is connected to the appliance housing, in particular at least partially fixed. The axis of rotation of the door can pass through the hinge.

[0021] In particular, the inner casing cover is part of the appliance door. If the appliance is designed as a household refrigeration appliance, the appliance door can be designed as a household refrigeration appliance door. In a closed state, the appliance door can delimit and / or close off the usable space on at least one side. In its installed state, the appliance door can have a side facing the usable space and a side facing away from it. The side facing away from the usable space could form an outer door surface. An inner door surface of the appliance door can be part of the inner liner. In particular, the side of the appliance door facing the usable space forms the inner door surface.

[0022] In the closed state, the appliance door conceals an opening plane of the appliance body, particularly the appliance itself, advantageously by an arrangement and / or orientation of the appliance door at least substantially parallel to the opening plane, wherein an at least substantially parallel direction to the opening plane deviates from a direction of the opening plane by less than 10%, preferably less than 5%, and particularly preferably less than 2%. In the open state, the appliance door could have a maximum opening angle of at least 90°, advantageously at least 180°, preferably at least 210°, and particularly preferably at most 270°, wherein the opening angle is advantageously measured relative to the opening plane of the appliance body.The closed state is preferably a state in which the appliance door, unlike the open state, abuts the appliance body. In the open state, the usable space is at least partially, and preferably completely, accessible to the user.

[0023] It is also conceivable that the inner liner is part of the appliance body and the appliance door. In the assembled state, the inner liner could simultaneously form at least part of the appliance body and the appliance door. The appliance body and / or the appliance door can / could consist at least partially and / or largely and / or entirely of metal, for example, aluminum, and / or a mineral, for example, glass, and / or preferably of a plastic and / or a composite material. The appliance body and / or the appliance door could / could, for example, be manufactured at least partially and / or largely by a deep-drawing process, a 3D printing process, or a sheet metal bending process. Preferably, the appliance body and / or the appliance door is / are manufactured largely, and preferably entirely, by an injection molding process or by thermoforming.

[0024] Advantageously, the surface element is made of a material, in particular a liquid or powdered coating material. For example, the surface element could be made at least partially of minerals, possibly pigments, in particular color pigments, and / or synthetic resin and / or binders and / or fillers. In the process for manufacturing and / or adapting the household appliance device, the material, in particular the coating material and / or the minerals, could be applied to the sub-area and at least metallurgically bonded to it. In the assembled state, the surface element is formed from the material and / or the minerals. It would also be conceivable for the surface element to be plate-like and / or made from a plate-like element, which is at least metallurgically bonded to the sub-area in the assembled state.

[0025] Preferably, the surface element is made of a film, in particular a hot-stamped foil. This increases both comfort and efficiency. Furthermore, the mounting of the surface element on an inner liner can be advantageously improved. Due to its film design, a particularly thin surface element can be provided, which can therefore be integrated and easily connected to the inner liner. This eliminates the need for openings in the inner liner for the surface element. In particular, this increases the flexibility of mounting the surface element. The film can thus be flexibly applied to any desired location on the inner liner, especially independent of any cutouts or die-cuts in the surface element. Consequently, the mounting and / or manufacturing of the surface element can be simplified, thereby reducing costs.

[0026] The surface element is particularly advantageous compared to components that are inflexible, especially dimensionally stable, due to their thickness, such as plate-shaped components. In the process for manufacturing and / or adapting the household appliance device, the film can be bonded to the inner liner, at least by a material bond. In particular, the film bonded to the inner liner forms the surface element in the assembled state. The surface element made from a film can, for example, consist at least partially or largely of a mineral, especially glass, and / or a metal and / or a metal alloy and / or a plastic and / or a carbon-containing material and / or a composite material. The film could also potentially consist of a colored plastic.

[0027] The film can be flexible and / or elastic. In particular, the film is flexible enough that, when the film is deformed, its curvature changes with respect to one direction of extension. For example, the film is non-destructively and preferably reversibly bendable and / or deflectable by at least 2%, advantageously at least 10%, preferably at least 20%, and most preferably at least 50% along its extension in a further direction perpendicular to that direction. An elastic film is understood to be one that can be repeatedly deformed without being mechanically damaged or destroyed, and in particular, that after deformation, the film returns to its original shape on its own. For example, the thickness of the film could be in a range between at least 50 nanometers and preferably at most 10 millimeters.In an unfolded state, the film could have a maximum thickness of at most 5 mm, in particular at most 2 mm, in particular at most 1 mm, advantageously at most 0.5 mm and particularly advantageously at most 0.05 mm.

[0028] When the surface element is hot-stamped onto a section of the inner liner, comfort, particularly user and / or assembly ease, can be significantly improved. Furthermore, the attachment of the surface element to the inner liner can be optimized, becoming more durable and / or secure. Additional fixing elements for connecting the surface element to the inner liner can also be eliminated. Moreover, the design can be improved in terms of integration, as the surface element can be particularly well integrated with the inner liner in the assembled state due to the hot-stamping process. This can reduce costs, especially manufacturing and / or assembly costs, as well as effort, particularly manufacturing and / or assembly effort. The surface element could be hot-stamped onto the section using either a hot-stamping roll process or a hot-stamping stroke process.The foil, particularly the hot stamping foil, could be bonded to the inner liner, at least materially, by pressure and heat. A detailed description of the manufacture and / or adaptation of the household appliance equipment for a hot stamping process is provided later in this document.

[0029] In a preferred embodiment of the invention, it is proposed that the surface element, in its assembled state, forms at least a decorative element. This enhances user comfort. The visual appearance of an inner liner can be improved by means of a surface element that at least partially forms a decorative element. A side of the inner liner facing a usable space is preferably made more visually appealing to the user by means of the surface element. In particular, visible surfaces of the inner liner can be adapted, especially enhanced and / or refined, with the surface element. With a potentially transparent surface element, the design can be further improved in terms of integration, since the surface element is visually indistinguishable from the inner liner to the user in its assembled state.This allows the surface element to be arranged and / or integrated on the inner liner in a particularly inconspicuous way for the user.

[0030] The surface element, which at least forms the decorative element, is preferably designed to alter at least one visual appearance of the inner liner. The surface element can create and / or provide a visual effect, for example, a specific color effect, for the user.

[0031] It would be conceivable that the surface element is at least partially, and preferably completely, visually adapted to the inner liner. In its assembled state, the surface element could have an appearance, for example, a color and / or a texture and / or a grain pattern, which is at least partially, and preferably completely, identical to at least one appearance, in particular a color and / or a texture and / or a grain pattern, of the inner liner, especially at least one side facing the usable space. Alternatively, the surface element could also be transparent and / or appear optically transparent to the operator, at least in its assembled state.The surface element, in particular the optical appearance of the surface element, may be indistinguishable to the operator in the assembled state from the optical appearance, for example the color and / or the structure and / or the grain, of the inner liner.

[0032] Preferably, the surface element, and in particular its visual appearance, is distinguishable to the operator in the assembled state from the visual appearance, for example, the color, structure, and / or grain, of the inner liner. Preferably, the surface element is arranged on the inner liner, at least decoratively. The surface element could display at least one piece of information, particularly for the user. This information could be at least one color, image, number, letter, logo, and / or brand name.

[0033] Alternatively and / or additionally, it is proposed that the surface element, in its assembled state, forms at least one functional element. This can further enhance comfort, particularly user comfort. If a surface element forms at least one functional element, at least a portion of an inner liner to which the surface element is connected in its assembled state can be advantageously protected. In particular, the functional element can prevent contamination, which could occur, for example, from particles in the environment, especially from a usable space, or from user contact, and / or damage, such as scratching. Furthermore, cleaning may be simplified.Furthermore, the surface element forming the functional element may be transparent, thus further improving integrability, as the surface element is visually indistinguishable from the inner liner to the user in the assembled state.

[0034] The surface element, which at least forms the functional element, is preferably designed to provide at least one protective effect and / or a function with special surface properties, such as a modified electrical conductivity compared to the inner liner, for the user. The functional element is preferably a protective element. Preferably, the functional element provides a protective function for the inner liner, in particular the relevant section. For example, the functional element could form a water-repellent layer and / or be a layer that is preferably impact-resistant and / or pressure-resistant and / or scratch-resistant.

[0035] It is also conceivable that the surface element, in its assembled state, constitutes both the decorative and functional element. In particular, the surface element possesses decorative as well as functional properties.

[0036] Furthermore, the invention relates to a method for manufacturing and / or adapting a household appliance device, in particular the aforementioned household appliance device.

[0037] It is proposed that, in a surface adaptation step, a surface element be bonded, at least materially, to at least one section of an inner liner facing a usable space. Such an assembly method can advantageously improve comfort, particularly user comfort, and increase product and / or cost efficiency. Specifically, the visual appearance of an inner liner can be at least partially modified and / or adapted by means of a surface adaptation step. It may be possible to connect a surface element to the inner liner for decorative and / or functional purposes, whereby at least the section of the inner liner can be advantageously protected from contamination and / or damage, particularly scratching, when the surface element is installed.

[0038] The method for manufacturing and / or adapting the household appliance device comprises several process steps and / or sub-steps of process steps. According to the invention, the method for manufacturing and / or adapting is a method for cladding and / or coating a partial area of ​​the inner liner.

[0039] According to the invention, the surface adaptation step takes place after a manufacturing step for producing the inner liner. This allows the inner liner to be flexibly adapted as needed, particularly in terms of appearance, even after manufacturing. This reduces comfort and costs, especially manufacturing and / or assembly costs. Consequently, efficiency can be further increased with regard to product efficiency and / or cost efficiency.

[0040] In this manufacturing step, the inner liner is produced. The inner liner could, for example, be produced at least partially and / or largely by deep drawing, particularly by thermoforming, by 3D printing, or by sheet metal bending. Preferably, the inner liner, and in particular all inner housing components, are produced largely, and preferably entirely, by injection molding. The inner liner could be produced from a blank, a compound, and / or a casting, for example, made of metal and / or plastic, particularly liquid plastic, in this manufacturing step, preferably by injection molding. The blank could be deformed in this manufacturing step, in particular such that the inner liner is produced. Preferably, after this manufacturing step and before the surface adaptation step, the inner liner is formed according to shape, and in particular completely, from the blank.

[0041] The inner liner is advantageously coated in the surface adaptation step. It might also be possible to lacquer or paint the inner liner in this step. In the inventive method for manufacturing and / or adapting the household appliance, it is proposed that the surface element be hot-stamped onto the portion of the appliance facing the usable area during the surface adaptation step. This further increases comfort, particularly user and / or assembly ease, as well as efficiency with regard to product efficiency and / or cost efficiency, especially by eliminating the need for complex and time-consuming manufacturing and / or assembly processes. Hot-stamping the surface element optimizes the fixation of a surface element to an inner liner, making it more durable and / or secure.Furthermore, integrability can be improved because the surface element, in the assembled state, can be particularly integrated with the inner liner due to the hot stamping.

[0042] In the surface adaptation step, the film is placed onto the blank or the inner liner. Pressure and heat advantageously bond the film to the inner liner, at least in a material-bonded manner. The film is preferably hot stamping foil. The hot stamping foil has at least one adhesive which bonds material-bonded to the blank or the inner liner in the surface adaptation step.

[0043] Due to the pressure and heat, the adhesive of the hot stamping foil is activated in the surface adaptation step.

[0044] The hot stamping of the surface element could be carried out in the surface adaptation step using a hot stamping stroke process and / or a hot stamping roll process. If the surface element is formed, and in particular manufactured, two-dimensionally on the partial area, the hot stamping roll process is preferred. Advantageously, in the case of a three-dimensional structuring of the inner liner, the hot stamping of the surface element is carried out using the hot stamping stroke process. In the hot stamping roll process, the film, in particular the hot stamping foil, is applied to the blank or the inner liner in a continuous rolling process using a heated stamping roller or a heated stamping wheel, preferably consisting of silicone and / or metal and / or a bonding material, and in particular is bonded to the blank or the inner liner at least materially.In the hot stamping stroke process, the foil, in particular the hot stamping foil, is applied to the blank or the inner liner in a tacked stroke motion using a heated stamping die, which is preferably made of silicone and / or metal and / or a dressing material, and in particular is bonded at least materially to the blank or the inner liner. Drawings

[0045] Further advantages become apparent from the following description of the drawings. The drawings illustrate two 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. They show:

[0046] Fig. 1 a household appliance designed as a household refrigerator with a household appliance device comprising an inner liner and a surface element at least materially bonded to the inner liner, Fig. 2 a schematically represented process flow diagram for the manufacture and / or adaptation of the household appliance device, Fig. 3 a household appliance with a household appliance device in an alternative embodiment, and Fig. 4 a schematically represented process flow diagram in an alternative embodiment for the manufacture and / or adaptation of the household appliance device according to Figure 3 . Description of the exemplary implementations

[0047] The Figure 1Figure 1 shows a household appliance 10a designed as a household refrigeration appliance, intended for use in a household. The household appliance 10a includes a household appliance device 12a. Accordingly, the household appliance device 12a is designed as a household refrigeration appliance device. In this case, the household refrigeration appliance is designed as a refrigerator. Alternatively and / or additionally, the household refrigeration appliance could also be designed as a chest freezer, freezer, refrigerator-freezer combination, and / or similar appliance.

[0048] The household appliance 12a has an inner liner 16a, which at least partially delimits a usable space 14a for storing goods. In the present case, the inner liner 16a is part of a housing 28a of the household appliance 12a. The inner liner 16a is a housing, in this case a plastic housing, that delimits the usable space 14a on at least five sides. The inner liner 16a has a side facing the usable space 14a and / or a side facing away from the usable space 14a. Figure 1Only the side facing usable space 14a is visible, as the side facing away from usable space 14a is enclosed by the device housing 28a. The inner liner 16a has at least one wall. In this example, the inner liner 16a has a back wall, a bottom wall, a top wall, and two opposing side walls (for clarity, these are not labeled). In this exemplary embodiment, a section 20a of the inner liner 16a facing usable space 14a extends vertically, at least partially, along the back wall of the inner liner 16a. This section 20a extends along the back wall up to a step 56a of the inner liner 16a (see figure). Figure 1 It is also conceivable that sub-area 20a extends over at least two walls, for example the back wall and the ceiling wall. Sub-area 20a could then extend over at least one edge area of ​​the inner liner 16a.

[0049] A household appliance door 30a of the household appliance device 12a is rotatably mounted on the appliance body 28a for opening and / or closing, for example by means of a hinge (see Figure 1). Figure 1 When open, usable space 14a is accessible to one user (as in Figure 1 (shown). In contrast to the open state, the appliance door 30a abuts the appliance body 28a when closed, thus limiting at least part of the usable space 14a (not shown).

[0050] The household appliance device 12a has a surface element 18a which, in an assembled state, is at least materially bonded to at least the part 20a of the inner liner 16a facing the usable space 14a (cf. Figure 1In its assembled state, the surface element 18a forms an interior visible surface of the inner liner 16a. The interior visible surface is a surface of the inner liner 16a facing the usable space 14a.

[0051] The surface element 18a is directly connected to the sub-area 20a, at least by a material bond. In this exemplary embodiment, the surface element 18a is designed as a coating 26a. The surface element 18a is made of a film 32a (see figure). Figure 2 ). Here, the surface element 18a is hot-stamped onto the sub-area 20a of the inner liner 16a.

[0052] In its assembled state, the surface element 18a forms at least one decorative element 36a. The surface element 18a, which forms at least the decorative element 36a, is intended to alter at least one visual appearance of the inner liner 16a. In this example, the surface element 18a has a visual effect, such as a color effect for the user (not shown). In this exemplary embodiment, the surface element 18a is arranged at least decoratively on the inner liner 16a and is distinguishable to the user from the visual appearance of the inner liner 16a, such as its color, structure, and / or grain. Alternatively, the surface element 18a could be at least partially indistinguishable to the user from the visual appearance of the inner liner 16a. The surface element 18a could also be optically transparent.

[0053] In the present exemplary embodiment, the surface element 18a, in its assembled state, also functions as at least one functional element 38a. The surface element 18a has both decorative and functional properties. However, it would also be conceivable that the surface element 18a, in its assembled state, functions solely as a decorative element 36a or as a functional element 38a.

[0054] The surface element 18a, which forms at least the functional element 38a, is designed to provide the user with at least a protective effect and / or a function with special surface properties, such as a modified electrical conductivity compared to the inner liner 16a. The functional element 38a is designed as a protective element. The functional element 38a provides a protective function for the inner liner 16a, specifically the sub-area 20a. For example, the functional element 38a could form a water-repellent layer and / or be a layer that is impact-resistant, scratch-resistant, and / or pressure-resistant. In a method for manufacturing or adapting the household appliance device 12a, the surface element 18a is bonded, at least materially, to at least the sub-area 20a facing the usable space 14a in a surface adaptation step 82a.

[0055] Innerliners 16a connected. The method for manufacturing and / or adapting the household appliance device 12a comprises several process steps and / or several sub-steps of the process steps. Here, the method is described only by means of a schematically represented process flow diagram in Figure 2 Described using an example.

[0056] In this exemplary embodiment of the invention, a manufacturing step 80a for the production of the inner liner 16a takes place before the surface adaptation step 82a. Figure 2Figure 8 shows a blank 50a. Here, the blank 50a is depicted as a plastic sheet. In manufacturing step 80a, the blank 50a is formed and the inner liner 16a is produced. In manufacturing step 80a, the inner liner 16a is produced, for example, at least partially and / or largely, by means of an injection molding process, a 3D printing process, or a sheet metal bending process. In this case, the inner liner 16a is produced entirely by means of a deep-drawing process, specifically thermoforming. After manufacturing step 80a, the inner liner 16a is completely formed from the blank 50a before the surface adaptation step 82a (see center figure in Figure 80a). Figure 2 ). Here, the inner liner 16a is one-piece, specifically designed as a single unit.

[0057] Following manufacturing step 80a, surface adaptation step 82a takes place, in which the surface element 18a is at least materially bonded to the sub-area 20a of the inner liner 16a. In surface adaptation step 82a, the inner liner 16a is coated. Here, a substance, specifically a coating material such as minerals, could be applied to the sub-area 20a and at least materially bonded to it. In this exemplary embodiment, the surface element 18a is produced from the film 32a (see right-hand figure in [reference]). Figure 2 The foil 32a is applied to the inner liner 16a and bonded to the inner liner 16a, specifically to the sub-area 20a, by means of hot stamping. In the surface adaptation step 82a, the surface element 18a is hot stamped onto the sub-area 20a facing the usable space 14a.

[0058] The foil 32a is a hot stamping foil. In the surface adaptation step 82a, the foil 32a is bonded to the inner liner 16a by pressure and heat, creating at least a material bond. The hot stamping foil contains at least one adhesive that bonds to the inner liner 16a in the surface adaptation step 82a. The adhesive in the hot stamping foil is activated by the pressure and heat. The hot stamping of the surface element 18a could be carried out in the surface adaptation step 82a using a hot stamping stroke process and / or a hot stamping unwinding process. This exemplary embodiment describes the hot stamping unwinding process. In the hot stamping unwinding process, the foil 32a is applied to the inner liner 16a in a continuous unwinding process using a heated stamping roller 52a, creating at least a material bond with the inner liner 16a.

[0059] In the Figures 3 and 4Another embodiment of the invention is shown. The following descriptions are essentially limited to the differences between the embodiments, whereby with regard to identical components, features and functions, reference is made to the description of the embodiment of the Figures 1 to 2 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 2 by the letter b in the reference numerals of the embodiment of the Figures 3 and 4 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 2 be referred.

[0060] In the present embodiment, shown in Figure 3Figure 1 shows a household appliance 10b designed as a household refrigeration appliance and intended for use in a household. The household appliance 10b has a household appliance device 12b. The household appliance device 12b has an inner liner 16b, which at least partially delimits a usable space 14b for storing goods. Figure 3 Figure 1 shows that the household appliance device 12b has a household appliance door 30b. In this alternative embodiment of the invention, the household appliance door 30b has the inner liner 16b. The household appliance device 12b has a surface element 18b which, in an assembled state, is at least materially bonded to at least one partial area 20b of the inner liner 16b facing the usable space 14b (see Figure 1). Figure 3In its assembled state, the surface element 18b forms an interior visible surface of the inner liner 16b. The interior visible surface is a surface of the inner liner 16b facing the usable space 14b.

[0061] In Figure 4 A schematic process flow diagram for the manufacture and / or adaptation of the household appliance device 12b described above is shown. In this alternative embodiment, a deformation step 84b for the production of the inner liner 16b takes place after a surface adaptation step 82b. Figure 4The left-hand figure shows a blank 50b. The blank 50b, specifically a surface of the blank 50b, is first adapted in the surface adaptation step 82b. In this step, a foil 32b, specifically a hot stamping foil, is hot stamped onto the blank 50b as previously described. The surface element 18b is made from the foil 32b. The hot stamping is also carried out using a hot stamping roll process with an embossing roller 52b. After the surface adaptation step 82b, the forming step 84b takes place, in which the blank 50b is formed. In this case, the blank 50b is formed as the inner liner 16b of the household appliance door 30b. In the assembled state, the surface element 18b is hot stamped onto the inner liner 16b.
