Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the design part is flat. That means it is plate-like or sheet-like.
  • 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.
  • these components are no longer exposed in the form of the channel wall and/or a wall of the inner container.
  • they are arranged in a protected manner on the one hand.
  • protection against the effects of force, such as impact or the like can be achieved here.
  • this specific design part also enables a very special visual appearance.
  • 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.
  • a certain light reflection surface can also be used due to the metallic-appearing surface of the design part.
  • 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.
  • hot embossing is a particularly advantageous method for enabling this protective film to be applied over a large area to the base plate.
  • 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.
  • 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.
  • 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.
  • the base plate is a separate component from the duct wall.
  • 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.
  • the design part can also be a design plate which has the base plate with the hot-stamping foil separate therefrom.
  • 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.
  • 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.
  • a design plate made essentially of plastic can be provided, which not only has the corresponding advantages with regard to the condensation problem.
  • 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.
  • 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.
  • 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.
  • At least some 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.
  • the holding elements are initially produced as separate components and are then fastened to the base plate, which is also produced separately.
  • a non-destructive connection can be provided here.
  • such a connection can be an adhesive connection.
  • At least one holding element can be a hanging element.
  • 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.
  • 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.
  • 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.
  • further existing holding elements can then be coupled more easily with counter-holding elements.
  • 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
  • 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.
  • 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.
  • a snap-on connection differs from a pure plug-in connection.
  • 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.
  • the snap connection must first be released again.
  • 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.
  • 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.
  • 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.
  • the plug-in elements can be formed in the lower corner areas of the design part.
  • 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.
  • a positionally fixed arrangement of the design part is particularly advantageous allows.
  • a fast and user-friendly installation scenario is also achieved.
  • 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.
  • the design part and the duct wall are then retained as separate components in the household refrigeration appliance in the final assembled state.
  • 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.
  • the design part only has the base plate and the hot-embossed protective film.
  • the design part then has no holding elements.
  • the design part, which is initially provided as a separate component is permanently connected to the duct wall, which is also manufactured separately.
  • 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.
  • these initially separate components are inextricably connected to one another.
  • this combination of components is attached to the rear wall of the inner container.
  • 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 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.
  • the duct wall is at least partially made of an expanded polystyrene (EPS).
  • EPS expanded polystyrene
  • 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
  • the base plate is made from a plastic that is different from EPS.
  • the base plate is 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.
  • 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
  • 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.
  • 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.
  • this advantageous air conduction concept for introducing cold air into the receiving space is also improved here.
  • 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.
  • the household refrigeration appliance is designed as a no-frost
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
