Description

Household refrigerating appliance with a wall element, which has a hot stamped

has foil

One aspect of the invention relates to a household refrigeration appliance with a housing. The household refrigeration appliance also has an inner container. This is arranged in the housing. The inner container has walls with which a volume of the household refrigeration appliance is limited. The household refrigeration appliance has a storage space for food. This forms a partial volume of the volume space. In addition, the household refrigeration appliance has an air duct system. As intended, cold air can be introduced into the receiving space with this. The air duct system has at least one air duct, which is delimited by a wall of the inner container and a duct wall that is separate therefrom. This channel wall is also part of the household refrigeration appliance. The duct wall is arranged in the volume space and delimits this receiving space, so that the air duct arranged in the volume space is separated from the receiving space.

So-called no-frost household refrigeration appliances are also known, for example, as household refrigeration appliances. These are designed according to the household refrigeration appliance mentioned above with a corresponding air duct system. In such no-frost household refrigeration appliances, an evaporator of the household refrigeration appliance is not arranged in a refrigeration compartment itself, but rather separately from it. In such systems, the generated cold air is then conducted from the evaporator via the air duct system into the receiving space, in particular the cooling compartment. In this context, no-frost domestic refrigeration appliances have the advantage that there is less condensation in this receiving space.

The duct wall in this regard is lined in conventional configurations or can, however, also be arranged unlined. It can also be present as a visible component.

On the other hand, it is also known that the walls of the inner container are exposed and in this respect the usual material used plastic is exposed. It is the object of the present invention to functionally improve the walls delimiting the receiving space.

This object is achieved by a household refrigeration appliance which has the features according to claim 1.

The household refrigeration appliance has a flat design part that appears metallic in appearance. This is arranged on the front of the duct wall, so that the duct wall is covered by the design part towards the receiving space. In addition or instead of this, a flat design part of the household refrigeration appliance that appears metallic can be arranged at least on a front side that faces the receiving space, at least on one wall of the inner container. Generally speaking, the design part is flat. That means it is plate-like or sheet-like.

In both of the above-mentioned alternatives, the design part can have at least one hot embossing foil, which is applied to a front side of a base plate of the household refrigeration appliance by hot embossing. A household refrigeration appliance designed in this way has several advantages in this respect. On the one hand, this makes it possible to cover the duct wall and/or at least one wall of the inner container with such a specific design part, at least in some areas towards the receiving space. As a result, the duct wall and/or the wall of the inner container no longer appears as a direct visible component, but is covered by the design part. This makes it possible in a particularly advantageous manner to cover wall areas that delimit the receiving space and that can be recognized by a user when viewing the receiving space, by such design parts. As a result, these components are no longer exposed in the form of the channel wall and/or a wall of the inner container. As a result, they are arranged in a protected manner on the one hand. For example, protection against the effects of force, such as impact or the like, can be achieved here. On the other hand, this specific design part also enables a very special visual appearance. In particular, the duct wall towards the receiving space and/or a wall of the inner container towards the receiving space can also be optically concealed in a very individual manner. Such an impression that appears metallic in this respect also enables other advantages. In this context, a certain light reflection surface can also be used due to the metallic-appearing surface of the design part. In this way, light that is generated in particular by at least one light source in the recording space itself can be specifically reflected. In this way, in particular, a more homogeneous and brighter illumination of the entire recording space can also be made possible. In this context, the configuration of the design part with a hot stamping foil is particularly advantageous. This makes it possible to apply a corresponding protective film, which appears metallic, very evenly and yet permanently and with high stability. It is therefore avoidable to use a metal plate made of real metal.

In this context, hot embossing is a particularly advantageous method for enabling this protective film to be applied over a large area to the base plate. Last but not least, the hot stamping also makes it possible for the design part to permanently retain this metallic appearance when it is exposed to a wide variety of environmental conditions. Even with corresponding temperature fluctuations and/or humidity fluctuations, the design part remains permanently highly functional thanks to this configuration with a hot stamping foil. This hot embossing also enables the protective film to be applied very bubble-free and without creasing. This also makes it possible to avoid shrinkage processes and the associated distortions of the protective film in an improved manner. In this regard, therefore, this hot stamping with the application of Hot stamping foil is particularly advantageous in many ways. This is particularly the case if such a protective film is to be applied over a correspondingly large area to the wall of the inner container and/or to the channel wall. In particular, this then relates to the application to the base plate mentioned.

In one embodiment, the base plate is made of plastic. In particular, it is made entirely of plastic.

The base plate is a separate component from the wall of an inner container. This can then be attached to the wall of the inner container.

In an advantageous embodiment, the base plate is a separate component from the duct wall. In this regard, in one embodiment, the design part, seen as a whole, can be a component that is separate from the channel wall. The design part can then be manufactured individually and independently of the duct wall. As a result, both with regard to the manufacturing process and with regard to the individual material use, on the one hand for the design part, in particular the base plate, and on the other hand for the channel wall, can result. With such a configuration, the assembly scenario on the one hand of the duct wall and on the other hand of the design part can then also take place individually.

Since the design part is a separate component from the duct wall or from the wall of the inner container, in one exemplary embodiment the design part can also be a design plate which has the base plate with the hot-stamping foil separate therefrom. In this way, a large-area, uniform and smooth application of the hot stamping foil to the base plate can be taken into account in an even better way. In particular, the material of the base plate can then be matched to the protective film or the hot stamping film in this context, so that this large-area, bubble-free and uniformly smooth application can be particularly taken into account. In this context, the material of the channel wall can then be designed independently of this and does not have to meet these requirements for the hot stamping foil. The embodiment of the base plate made of plastic is also particularly advantageous in that, in comparison to a metal plate, in particular a solid plate made of real metal, significantly fewer condensation spots occur. Due to the design made of plastic, a more uniform temperature distribution over the entire design part is made possible here and local dew points, on which a liquid is correspondingly deposited, can thus also be avoided in particular. In particular, this is a significant advantage over configurations of a base plate that are basically made of metal. Therefore, especially in this context, the embodiment with a separate protective film, which has a metallic appearance and is applied to the base plate with hot embossing, is particularly advantageous. In this context, in one exemplary embodiment, a design plate made essentially of plastic can be provided, which not only has the corresponding advantages with regard to the condensation problem. In addition, such a configuration with a base plate and a hot stamping foil applied thereto enables improved cleaning, in particular wiping at the front. Such a protective film is easier to clean and to keep clean in this respect. In addition, such an embodiment of the design part with a base plate made of plastic and a protective film hot-embossed thereon also results in an advantageous embodiment in terms of material costs. A corresponding reduction in costs is made possible in this respect, in particular in comparison to an embodiment of such a design part made of real metal. Also, the weight can be reduced compared to a metal plate.

In one exemplary embodiment, the design part has a number of holding elements. With which is intended that the design part is attached to the inner container. This is particularly advantageous when the design part is a component that is separate from the walls of the inner container. These holding elements can then enable the design part to be attached in a simple and yet mechanically secure and precisely positioned manner.

In one exemplary embodiment, it can be provided that at least some holding elements, in particular all holding elements, are formed in one piece with the base plate of the design part. The base plate with the integrated holding elements is thus produced by a production process, for example by injection molding. In another exemplary embodiment, it can be provided that the holding elements are initially produced as separate components and are then fastened to the base plate, which is also produced separately. For example, a non-destructive connection can be provided here. In particular, such a connection can be an adhesive connection.

In one embodiment, at least one holding element can be a hanging element. This is intended so that the design part can be attached to a counter-hanging element, which is arranged on a rear wall of the inner container, in particular from above. As a result, an attachment or suspension connection is created between the design part and the rear wall. The design part is then attached from above directly to this rear wall of the inner container, which represents a corresponding wall of the inner container. This allows for a very simple attachment scenario for the design part on this rear wall. Furthermore, this also makes it possible for this mechanical connection to be established between the hanging element and the counter-hanging element when there are several holding elements, thereby creating a pre-assembly position of the design part on the rear wall. A certain alignment of the design part to the rear wall is thus already achieved. In the further assembly process, further existing holding elements can then be coupled more easily with counter-holding elements.

In one embodiment, the hanging element can be a hanging receptacle. The hanging receptacle can be closed at the top. That

Counter hanging element can be a hanging pin. If the design part is brought up to the rear wall from above during assembly, the hanging element then surrounds the counter-hanging element from above, so that the design part is virtually attached to the

Counter-hanging element is attached.

In particular, the hanging element and the counter-hanging element are formed in the width direction of the household refrigeration appliance centrally on the design part on the one hand and on the rear wall on the other hand. In one embodiment, at least one retaining element can be a snap element. This is intended to be snapped onto a counter-snapping element which is arranged on a rear wall of the inner container. In this context, a snap-on connection differs from a pure plug-in connection. In this regard, a snap connection is, on the one hand, a fitting of the snap element with the counter snap element and, at the same time, also a related snapping and thus fixing of these elements to one another in at least one spatial direction. This snapped state then prevents the snap connection that has been produced from being pulled apart in the direction of bringing them into one another. In this regard, the snap connection must first be released again. In particular, the snap element can engage behind the counter-snap element in this context in order to adjust the snapped state in this regard.

The design part preferably has a plurality of, in particular at least two, in particular at least three, in particular at least four, snap-on elements which can be snapped on with a corresponding number of counter-snap-on elements.

In one embodiment, at least one of the holding elements can be a plug-in element or a plug-in element. This is intended to be plugged together with a mating plug-in element, which is arranged on a rear wall of the inner container. In this respect, such a plug-in connection is merely a fitting into one another, in which case the plug-in element or the plug-in element and the mating plug-in element are not additionally snapped on in some other way, as is the case with a snap-on connection. In one embodiment, there may be two male members and two mating male members. In particular, the plug-in elements can be formed in the lower corner areas of the design part.

In particular, it can be provided that in one exemplary embodiment at least one retaining element is designed as a hanging element, in particular at least two retaining elements are designed as snap-in elements and at least two retaining elements are designed as insertion elements. As a result, a positionally fixed arrangement of the design part is particularly advantageous allows. Furthermore, a fast and user-friendly installation scenario is also achieved.

In one exemplary embodiment, the channel wall has passages through which holding elements that are formed on the design part extend. This is provided in particular when the design part is a component that is separate from the duct wall. In this context, the design part and the duct wall are then retained as separate components in the household refrigeration appliance in the final assembled state. In particular, it is then also possible to release this assembled state reversiblely and then in turn to disassemble the duct wall on the one hand and the design part on the other. These passages in the duct wall also make it possible for the design part to be attached directly to the rear wall of the inner container and for the duct wall to still be positioned in between. A simple assembly concept can thus be achieved which, moreover, is also designed to save space. Because the retaining elements reach through the channel wall, so to speak, it is also possible to easily mount the design part together with the channel wall on this rear wall of the inner container.

In another embodiment, it is possible that the design part only has the base plate and the hot-embossed protective film. The design part then has no holding elements. This is particularly advantageous when the design part, which is initially provided as a separate component, is permanently connected to the duct wall, which is also manufactured separately. For example, the design part, which has the base plate and the hot-embossed protective film, can then be attached to the front side of the duct wall by means of an adhesive connection. In such an embodiment, these initially separate components are inextricably connected to one another. In this exemplary embodiment, it can then be provided that this combination of components is attached to the rear wall of the inner container.

In one embodiment, at least 90% of the area of the front side of the duct wall, in particular 100%, is covered with the design part towards the receiving space. This is a correspondingly large-area covering of the duct wall to the receiving space reached through the design part. The advantages already mentioned above are then particularly prominent.

In one exemplary embodiment, the design part that is not made of real metal is designed to appear made of stainless steel. This can be achieved in particular in that the protective film embossed by hot embossing or the hot embossing film creates a corresponding metallic optical impression. This can be the case with appropriate coloring.

In one embodiment, the duct wall is at least partially made of an expanded polystyrene (EPS). This is particularly advantageous for this channel wall. On the one hand with regard to the corresponding requirements, on the other hand with regard to the minimized weight. Especially when the channel wall is made of this material, it is then advantageous to provide the design part as a separate component, to which this hot-embossed protective film is then applied. Since this expanded polystyrene in terms of influence in a hot stamping process

Can have disadvantages, such a solution with a separate configuration of a design part is advantageous in this respect. These components, the duct wall on the one hand and the design part on the other hand, can then be assigned individual functions in the best possible way and the individual ones

Material requirements can thus be taken into account in the best possible way.

In particular, the base plate is made from a plastic that is different from EPS. In particular, made of a plastic that is more temperature-resistant than EPS. The conditions required for hot embossing can thus be better taken into account. A high degree of dimensional stability of the base plate can then be maintained during hot stamping. A distortion-free application of the protective film by hot embossing is thereby made possible again in an improved manner.

In one embodiment, the design part has a height greater than or equal to 40 cm, in particular between 40 cm and 140 cm. In addition to or instead of this, the design part has a width greater than or equal to 30 cm, in particular between 30 cm and 80 cm. Relatively large-area design parts are thus provided, which also make it possible to have large-area walls of an inner container and/or large-area ok

Cover duct walls as large as possible towards the recording room. In order to take this aspect of the large-area coverage into account, the exemplary embodiment of the design part with a base plate made of plastic and the protective film applied thereto by hot embossing is particularly advantageous. Because it is precisely with such large areas that it is now also possible to generate a very even, bubble-free and crease-free, optically metallic impression on the front. In particular, this is achieved by the proposed concept and the use of a real metal plate can be avoided.

In one embodiment, the plate-like duct wall has an integrated flow duct structure on a rear side facing away from the receiving space, with which flow paths with air outlet points of the air duct are specified. Thus, this advantageous air conduction concept for introducing cold air into the receiving space is also improved here. Due to this integrated structure, the duct wall can also be used multifunctionally. It not only covers the air duct directly, but also provides this corresponding structure for targeted air conduction.

In one embodiment, the household refrigeration appliance is designed as a no-frost

Household refrigeration appliance trained.

This has advantages when creating large-area design parts.

A no-frost household refrigeration appliance is equipped with no-frost technology, which has a no-frost unit. A technical process is referred to as no-frost technology, in which the air humidity is reduced, in particular in an interior space designed as a freezer space or space for receiving food. As a result, the food does not frost, or does so to a significantly reduced extent, and the freezer compartment does not have to be defrosted or only has to be carried out in significantly reduced time cycles. With such a no-frost technique, cooling elements designed as cooling fins, for example, and thus a heat exchanger of the secondary circuit, are located in a separate area in the interior. During the cooling phase, a fan then draws the cold air from this separated area into the interior and thus into the freezer compartment. These devices are designed in such a way that air circulates through all compartments of the interior and again as a circuit enters the partitioned area. Because cold air holds less moisture, it mainly condenses as frost only on the heat exchanger of the secondary refrigeration circuit, which is located in the separated area and is the coldest point in the no-frost appliance that has contact with air. Provision can then be made for a defrosting mode to be carried out at specific time intervals, in which this first heat exchanger is defrosted in the separated area. For this purpose, in particular, a heating device is provided in the no-frost household refrigeration appliance, through which heating of this heat exchanger is carried out. The water that then forms from the thawing layer of ice can run out of the interior and thus also out of the device via a drainage channel and can be collected in a collection tray, which can also serve as an evaporation container. In particular, the fan is deactivated in the defrost mode so that the freezer compartment remains cooled. The no-frost technology significantly reduces the icing of cooling fins and the humidity in the entire household refrigeration appliance drops, which also significantly reduces the formation of layers of ice.

With an exemplary, relatively simple method, the humidity in a no-frost device is significantly reduced, at least in the freezer compartment. This is achieved in particular by separating the cooling fins from the actual cooling area or cooling compartment, with the cold air being conveyed into the freezer interior or the freezer compartment using a fan.

Due to the air duct system of the domestic refrigeration appliance, this cold air then circulates as a cycle through all compartments, including a refrigeration compartment, of the refrigeration appliance and re-enters the refrigeration part. Since it can only poorly absorb moisture and hold it less well, this is reflected on the cooling fins. These are heated and defrosted at regular time intervals and the water preferably reaches an evaporation tank via a channel, for example. The humidity in the entire device drops and almost no layers of ice form. In contrast to conventional appliances, most of the moisture that forms, which leads to the icing of conventional freezers, accumulates in the separate area of the cooling fins in household refrigeration appliances with no-frost technology. The indications "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction" etc. are the intended use and intended arrangement of the food storage container or the storage container device or the household refrigeration appliance given positions and orientations.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

In Fig. 1, a domestic refrigerator 1 is shown in a schematic representation, which is designed for storing and preserving food. The household refrigeration appliance 1 is a fridge-freezer combination appliance. It has a housing 2 in which a first receiving space 3 is formed, which is a cooling compartment in the exemplary embodiment. The first receiving space 3 is delimited by walls of an inner container 4 . At the front, the inner container 4 and thus also the first receiving space 3 has a loading opening 5, which in the exemplary embodiment is closed by two separate doors 6 and 7 is lockable. The loading opening 5 is a continuous uninterrupted opening and the first receiving space 3 is a continuous and uninterrupted space. The two doors 6 and 7 are pivotably arranged on the housing 2 via pivot axes that are each vertically oriented and thus oriented in the vertical direction (y-direction).

In the exemplary embodiment, the household refrigeration appliance 1 also has a second receiving space 8 that is separate from the first receiving space 3 . This one is a freezer here. The second receiving space 8 is arranged below the first receiving space 3 here, in particular in the vertical direction and thus viewed in the vertical direction. In the height direction, the two receiving spaces 3 and 8 are arranged without overlapping. The second receiving space 8 can be closed at the front by a separate third door 9, this door 9 being designed in particular as a front wall of a drawer which can be moved in the depth direction (z-direction) and which can be pushed into and pulled out of the second receiving space 8. The doors 6, 7 and 9 are arranged without overlapping each other and positioned next to each other at the front. In particular, they represent front end parts or visible parts of the household refrigeration appliance 1.

The inner container 4 has walls which delimit at least the first receiving space 3 here. The inner container 4 can be designed in one piece. In one exemplary embodiment, it can also additionally be designed to delimit the second receiving space 8 with walls. To delimit the first receiving space 3, the inner container 4 has vertical side walls 4a and 4b, a rear wall 4c, a bottom wall 4d and a top wall 4e as its walls. The rear wall 4c cannot be seen in the exemplary embodiment according to FIG. Because the household refrigeration appliance 1 also has a duct wall 10 which delimits the rear wall 4c of the inner container toward the second receiving space 3 . The channel wall 10 is also covered towards the front in the exemplary embodiment. For this purpose, a flat, in particular plate-like or leaf-like, design part 17 of the household refrigeration appliance 1 is arranged.

The receiving space 3 is thus delimited to the rear by the separate channel wall 10 . In this regard, the plate-like channel wall 10 is a separate component from the inner container 4 . Viewed as a whole, a volume space 11 is delimited by the walls 4a to 4e. A partial volume of this volume space 11 is the receiving space 3. The further partial volume is formed by that area which is formed in the depth direction behind the duct wall 10 and thus between the duct wall 10 and the rear wall 4c.

In the exemplary embodiment, the household refrigeration appliance 1 is a no-frost household refrigeration appliance.

In Fig. 2, a perspective cut view of partial components of an embodiment of a household refrigeration appliance 1 is shown in a vertical sectional view. As can be seen here, the N-frost domestic refrigeration appliance 1 shown here has a no-frost unit 12 . This is arranged in a lower area of the household refrigeration appliance 1 . It has an evaporator 13 and a fan 14 . Cold air generated in the area of the evaporator 13 is circulated in the domestic refrigeration appliance 1 by means of this fan 14 . It is also routed to recording room 3. For this purpose, this no-frost household refrigeration appliance 1 has an air duct system 15 . This has at least one air duct 16 . Viewed in the vertical direction, the air duct 16 adjoins the no-frost unit 12 at the top. As a result, the cold air that is generated in the no-frost unit 12 can be directed into the air duct 16 . From there it can be routed into the first receiving space 3 via appropriate air outlets or air outlet points. In one exemplary embodiment, this air in the receiving space 3 is then conveyed back or routed back to the no-frost unit 12 by appropriate circulation. In particular, this no-frost unit 12 can be formed in a lower area, viewed in the height direction, and in a rear area, viewed in the depth direction, of the first receiving space 3 .

In this regard, only the upper partial section of the household refrigeration appliance 1 is shown in FIG.

In one exemplary embodiment, the no-frost unit 12 can also extend, in particular, into the second receiving space 8 and is also arranged there in the rear area. The air duct 16 is directly delimited at the rear by the rear wall 4c. Towards the front it is directly delimited by the channel wall 10 . In one exemplary embodiment, the duct wall 10 is made of expanded polystyrene at least in regions, in particular completely. The air duct 16 is arranged in the volume space 11 . It is separated from the receiving space 3 by the channel wall 10 .

The household refrigeration appliance 1 also has at least one flat design part 17 that appears metallic in appearance, as can be seen in FIGS. 1 to 3. Here, FIG. 3 shows a horizontal sectional representation through the components according to FIG. In particular, this plate-shaped design part, which can also be referred to as a dimensionally stable design plate, is arranged and dimensioned in such a way that it covers at least 90%, in particular 100%, of the front side of the duct wall 10 .

In one exemplary embodiment, the design part 17 has a base plate 18, as can be seen in the horizontal sectional illustration in FIG. In one exemplary embodiment, the base plate 18 is made of plastic. In particular, the plastic is different from an expanded polystyrene. The plastic of the base plate 18 is preferably more temperature-resistant than the expanded polystyrene.

In one exemplary embodiment, the design part 17 is a component that is separate from the duct wall 10 .

In one exemplary embodiment, the design part 17 also has a hot stamping foil 19 . This can also be referred to as a protective film applied by hot stamping. This hot stamping foil 19 is applied at least to a front side of the base plate 18 by hot stamping. It covers the front of the base plate 18 completely. In particular, this hot stamping foil 19 is designed with an optically metallic appearance.

In one embodiment, in addition to or instead of this, at least one inside of at least one wall of the inner container 4 can be provided with a design part 17 . It is possible that this optical appearance corresponds to a stainless steel look.

In one exemplary embodiment, the design part 17 has a height greater than or equal to 40 cm, in particular between 40 cm and 140 cm. In one exemplary embodiment, the design part 17 has a width (measured in the width direction—x direction) greater than or equal to 30 cm, in particular between 30 cm and 80 cm.

In one exemplary embodiment, the channel wall 10 and the design part 17 are separate components from a front wall 20 (FIG. 2). The front wall 20 can be a front cover of the no-frost unit 12 .

FIG. 4 shows a partial area of the inner container 4 in a front view. A view of the back 4c is shown here. In one embodiment, a counter-hanging element 21 is formed on this rear side 4c. This can be designed as a suspension pin.

In the exemplary embodiment, counter-snapping elements 22, 23, 24 and 25 are also integrated into this rear wall and are therefore formed in one piece with it. These are intended to be snapped onto snap-on elements that are formed on the design part 17 . In one embodiment, mating plug-in elements 26 and 27 are also integrally formed in this rear wall 4c. Both the only one counter-hanging element 21 here and the counter-snapping elements 22 to 25 preferably provided here as well as the counter-plug elements 26 to 27 preferably provided here are holding elements which are designed for direct mechanical coupling with holding elements on the design part 17.

In this context, an embodiment of a design part 17 is shown in FIG. 5 in a perspective view. Here the design part 17 is shown in rear view so that the base plate 18 can be seen. In the installed state, the rear side faces the rear wall 4c. In the exemplary embodiment shown, the base plate 18 has a hook-in element 28 as a holding element. This is intended for hanging coupling with the counter hanging element 21 intended. It is formed here in the center of the base plate 18 viewed in the width direction. It can be provided that on the base plate 18 several snap elements 29, 30, 31 and 32 are designed as snap elements. These are intended to be snapped onto the counter-snapping elements 22 to 25 .

In addition, it can be seen in FIG. 6 in an exemplary embodiment that a flow channel structure 42 is integrally formed on the rear side of the channel wall 10 facing away from the design part 17 . As a result, different flow paths 43, 44, 45, 46, 47 and 48 are specified in a defined manner. These flow paths 43 to 48 each have at the edge Air outlet points of the air duct 16 on. The cold air can then escape from the air duct 16 via these air outlet points and enter the receiving space 3 .

FIG. 7 shows the mounted state of the arrangement 49, as shown in FIG. 6, on the rear wall 4c in a vertical sectional view. The coupled state between the counter hanging element 21 and the hanging element 28 is shown here. As a result, the design part 17 is suspended from above on this counter-hanging element 21 . Furthermore, a snapped state between a snap element, for example the snap element 30, with the counter snap element 23 is shown in FIG. 8 in a sectional view.

When the design part 17 is in the assembled state, the plug-in elements 33 and 34 also engage in the mating plug-in elements 26 and 27 .

FIG. 9 shows a representation corresponding to FIG. However, here the no-frost unit 12 is only shown in a pre-assembly state. The arrangement 49, on the other hand, is already shown in its assembled end state. Starting from the intermediate assembly state of the no-frost unit 12 shown in FIG. 9, this no-frost unit 12 is then brought into its final position by pivoting, as can then be seen in FIG.

In one exemplary embodiment, provision can be made for the front wall 20 to be snapped onto the inner container 4 by means of snap connections. In one exemplary embodiment, it can also be provided that a roof element 20a is connected in an interlocking manner to a web 50 (FIG. 9) protruding forward. The web 50 can be part of the duct wall 10 . Reference List
