Description

Door rack for a household refrigerator with illuminable

Cavity, door and door device

The invention relates to a door rack for a door of a household refrigerator. The door rack has an illuminable, tub-like container for holding food. The invention also relates to a door, a door device and a household refrigerator.

Door racks for household refrigerators are known in a wide variety of configurations. They usually have a tub-like container into which food can be placed. Such tub-like containers can be open at the top or covered by a cover that can be pivotably mounted. The visibility of door racks is usually impaired, in particular the visibility of the food stored therein is then restricted.

In order to improve this, a door rack is known from WO 2005/024323 A1, for example, which can be illuminated. For this purpose, an OLED (organic light-emitting diode) film is attached to the door rack. Such a configuration requires the use of such relatively expensive films. In addition, the movement of the foils there on the vertical edges of the container is disadvantageous because the foils can be mechanically impaired by contact with the food or other components on the outside of the container and, for example, be scratched or scraped off.

It is the object of the present invention to provide a door rack, a door, a door device and a household refrigeration appliance in which the lighting of the door rack is improved.

This object is achieved by a door rack, a door, a door device and a household refrigerator according to the independent claims.

One aspect of the invention relates to a door rack for a door of a household refrigerator. The door rack has a tub-like container for Ingesting food. The door rack is designed in such a way that the tub-like container can be illuminated over certain shape-specifically defined areas in other areas. The container has a cavity for coupling in light and for scattering the coupled light. The door rack itself thus has an integrated hollow chamber which is designed in such a way that light from a light source can be illuminated or radiated in a targeted manner, the light then being able to be scattered in a targeted manner through the hollow space. Such a configuration makes it possible for a light source to be locally variable and positionable in the most varied of places, and yet the light irradiation for illuminating the door rack can be targeted and safe in such a way that the illumination of the tub-like container is improved. As a result, the light source can be positioned externally to the door rack or internally to the door rack in such a way that it is arranged in a protected manner and is protected from the influences of the food in the tub-like container as well as from other components. Even when the door rack is removed from the door, the frictional forces that occur with the fastening elements that are arranged on the door cannot have any influence on the light source.

In addition, a very circumferential coupling of light and also a very circumferential light scattering are possible precisely through such a configuration of a cavity, so that the cavity also serves as a particularly advantageous optical component to enable a circumferential and then relatively homogeneous light distribution. This also enables the interior volume of the container to be illuminated extensively and uniformly. Such a configuration then also makes it possible that the light is not generated and irradiated via a light source arranged directly in the volume of the container, but such a light source can be arranged externally to this volume of the tub-like container.

In an advantageous embodiment it is provided that the cavity is formed in one piece on the container. As a result, a component-minimized design of the door rack can be created. In addition, the position between the cavity and the container is also permanently fixed, so that the respective light irradiation and the scattering of the coupled-in light, in particular then also into the volume of the container, can take place permanently in the same way. It is preferably provided that the cavity is formed under a bottom of the trough-like container. On the one hand, it is also protected and arranged to save space. On the other hand, a particularly advantageous and circumferential scattering of the light from the cavity via the bottom of the container into the volume of the container is then made possible. A very extensive and then even light scattering into the volume of the container via the floor is then made possible.

In an advantageous embodiment it is provided that the cavity is formed over the entire extent of the floor. In particular, the bottom of the container is thus designed to be double-walled, with an air volume then being formed between these walls. When viewed as a projection onto the door rack, the cavity is thus designed in terms of area to be the same as the floor or substantially the same as the floor of the container. This allows the light to be scattered particularly extensively from a cavity over virtually the entire surface of the base into the volume of the container. A very extensive illumination of this inner volume of the container, seen from the underside, is thereby made possible.

In addition, such a configuration of the cavity under a bottom of the container also enables light coupled into the cavity to be scattered and emitted downward from the cavity on the side facing away from the bottom, so that the door rack in that sense is then quasi also can serve as a lighting component for components external to the door rack, in particular also components arranged below the door rack in a household refrigerator. As a result, a multifunctional lighting option is created in a defined manner. On the one hand, targeted lighting of the interior volume of the container from below through the bottom of the container, and on the other hand, on the side facing away from the floor, downwards out of the door rack.

The cavity is advantageously delimited at the top by the bottom of the container. The floor thus forms a direct delimitation wall of the cavity itself. As a result, a compact cavity can be created and additional walls that are intended to delimit the cavity towards the door rack are then not required. Advantageously, the cavity below the floor is delimited by a floor plate spaced from the floor. In particular, the base plate has surface dimensions that correspond to the bottom of the container. In this context, the cavity is designed as a flat shaft which is practically formed by its boundary walls over the entire dimensions of the bottom of the container. Such a configuration then also has the advantage that light coupled into the cavity can be radiated into the cavity with the maximum amount of light and a relatively large amount of light is not otherwise radiated past the cavity before it is radiated into the cavity.

Provision is advantageously made for the base plate to be transparent at least in some areas. As a result, the advantage already mentioned above can be achieved to a particular extent that light can also be scattered downwards in a defined manner on the side facing away from the container, even out of the door rack.

It is preferably provided that the bottom of the container is at least partially transparent. In a correspondingly advantageous manner, it is then possible in a targeted manner to scatter the light coupled into the cavity through the bottom of the container into the interior volume of the container.

It is preferably provided that the cavity, viewed in the depth direction of the door rack, is delimited at a front end of the container by a front wall and is therefore closed on the front in this regard. This advantageously prevents dust or dirt or liquids or the like from entering the cavity from the front. In addition, a mechanically stable attachment of the cavity or the walls delimiting the cavity to the container is also made possible by such a configuration. Last but not least, this also enables the container itself to be stiffened.

It is preferably provided that the cavity, viewed in the depth direction of the door rack, is designed to be open at its rear end. Such a configuration makes it possible on the one hand in a particularly advantageous manner to radiate light into the cavity via this rear opening. On the other hand it is this then also makes it possible to intervene in the cavity, for example to be able to clean the cavity.

It is preferably provided that the door rack is formed in one piece with the cavity.

It is preferably provided that the door rack has a front wall which is separate from the container and which covers the front of the container over its entire front height. This means that the front of the container can be protected by this additional component. Furthermore, it is then also prevented, in particular if this front wall is at least partially non-transparent and therefore also opaque, that the light coupled into the cavity is undesired from the front and that an observer is not dazzled when looking at the door storage from the front.

Another aspect relates to a door for a household refrigerator, the door having at least one door rack according to the above aspect or an advantageous embodiment thereof. The door also has a lighting device for illuminating the cavity. It is provided in an advantageous embodiment that this lighting device is arranged externally to the door rack and is individually positioned on the door itself. In this context, it can be provided that the lighting device is arranged on an inner wall of the door and is positioned adjacent to the cavity. In particular, it is provided that the lighting device is arranged such that it is arranged directly adjacent to the rear opening of the cavity so that the light can be radiated into the cavity directly via this rear opening of the cavity.

It is preferably provided that the base plate, which delimits the cavity at the bottom, has such a depth in the depth direction that its rear edge rests against the inner wall of the door. On the one hand, the radiation of the light into the cavity is particularly advantageous and circumferentially possible, so that the light then does not pass through a base plate shortened in this regard between a gap between the rear edge, especially with a lighting device external to the door compartment the bottom plate and the inner wall of the door would leak downwards. On the other hand, this configuration also means that the positioning of the door rack on the inner wall is improved by the rear edge of this base plate resting against the inner wall. In addition, the cavity is then also more or less closed at the rear, in particular by the inner wall of the door.

It is preferably provided that the lighting device is arranged externally and thus outside the door rack on the door and the light from the lighting device is radiated directly into the cavity via this rear opening of the cavity.

It is then also possible for the light coupled into the cavity to be simultaneously scattered both upwards through the bottom of the container into the interior volume of the container and downwards through the base plate out of the door rack.

In a very advantageous manner, this above-mentioned embodiment of the door rack means that the lighting device is separate and separate from the door rack. As a result, the door rack can on the one hand, as explained above, be illuminated very individually and extensively, on the other hand the lighting device is then also very protected and can be positioned safely. A further essential advantage is then also to be seen in the fact that the door rack, which is preferably made in one piece from plastic, can be cleaned without problems and, for example, can then also be placed in a dishwasher. Since, in an advantageous embodiment, the lighting device is no longer arranged directly on the door rack itself, this can simply be cleaned extensively with water or other cleaning agents without a lighting device being adversely affected by this cleaning process. It is preferably provided that the lighting device has a plurality of light-emitting diodes. As a result, it has a compact design and can be operated in an energy-efficient manner.

Another aspect of the invention relates to a door device with a first door according to the above aspect or an advantageous embodiment thereof and with a a separate second door, which is arranged pivotably on the first door and, in the closed state, at least partially covers the front of the first door, the second door being pivotable relative to the first door. In a coupled state of the doors, the second door is coupled in terms of movement to the first door and can be pivoted together with the first door, the door rack being arranged in a storage room of the door device which is arranged on the first door and which can be closed at the front by the second door . The storage room is designed to be open towards the second door, so that it is accessible from the front when the first door is closed and the second door is open. Such a door-to-door system, which can then be part of a household refrigerator, in the closed state of the first door, through which a receiving space for food, such as a refrigerator compartment or a freezer compartment, of the household refrigerator can still access the storage room the door device itself are made possible without undesirable cold energy could escape from the receiving space. To do this, only the second door then has to be opened and access to the storage room is achieved. In particular, bottles can be stored in the storage room, which can then be easily removed or placed. The door rack is then designed in particular to hold bottles. The door device thus has in particular an intermediate space which is formed by the storage room and which is bordered to the front and to the rear by the two doors. The storage room is thus also pivoted when the entire door device is pivoted relative to the housing of the domestic refrigeration appliance, in order in particular to gain access to the receiving space.

Another aspect of the invention relates to a domestic refrigerator with a door, as mentioned above.

With information "above", "below", "front", "rear," horizontal "," vertical "," depth direction "," width direction "," height direction "etc. are the information given when the door rack or door rack is used and arranged as intended. the positions and orientations given on the door or device.

Further features of the invention emerge from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as those mentioned below in the description of the figures and / or features and combinations of features shown alone in the figures can be used not only in the respectively specified combination, but also in other combinations or alone, without departing from the scope of the invention. There are thus also embodiments of the invention to be considered as encompassed and disclosed, which are not explicitly shown and explained in the figures, but emerge from the explained embodiments and can be generated by separate combinations of features. Designs and combinations of features are also to be regarded as disclosed, which therefore do not have all the features of an originally formulated independent claim.

Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1, an embodiment of a household refrigerator 1 is shown in a schematic representation, which can be, for example, a refrigerator or a freezer or a combined refrigerator-freezer. The domestic refrigeration appliance 1, which is designed for storing and preserving food, has a housing 2 in which at least one receiving space 3 is designed for food. The receiving space 3 is preferably a cooling compartment here.

In addition, the household refrigerator 1 has a door 4 which is pivotably arranged on the housing 2. The door 4 is designed to close the receiving space 3 at the front. The door 4 has an inner wall 5 which, when the door 4 is closed, faces the receiving space 3. At least one door rack 6 is arranged on this inner wall 5. The door rack 6 is designed to hold food and is preferably designed in its basic geometry as an elongated cuboid.

In Fig. 2, the door 4 is shown in a simplified illustration with an embodiment of a door rack 6 arranged thereon. The door rack 6 has a tub-like container 7 which is formed in one piece from plastic. The trough-like container 7 is open at the top, so that a receiving volume 8 is accessible from above. This trough-like container 7 has a circumferential delimiting edge 9 which opens onto a base 10. In addition, the tub-like container 7 has a cavity 11 which is designed for coupling in light and for scattering the coupled-in light. The cavity, viewed in the height direction (y-direction), is formed below the floor 10 directly adjoining the floor 10. The cavity 11 is integrated and formed in one piece with the tub-like container 7. Viewed upwards in the height direction, the cavity 11 is directly delimited by the floor 10. The cavity 11 is delimited at the bottom by a separate base plate 13, which is separate from the base 10. The bottom plate 13 is in ok

Offset in height direction downwards and at a distance from the floor 10. The cavity 11 is also delimited to the side, with lateral delimiting walls 14 being provided here as viewed in the width direction (x direction).

In addition, in the exemplary embodiment shown, the door rack 6 has an additional, separate front wall 15. As can be seen, the front wall extends over the entire width of the container 7. When viewed in the vertical direction, the front wall 15 protrudes over the edge 9 of the container 7 upwards, in particular protrudes significantly upwards.

Additional side walls, not shown here, can be attached to holding elements 16 and 17, which are arranged on the front wall 15, and can, for example, also have the same height as the front wall 15. As a result, the tub-like container 7 is additionally enclosed on the front side and on the side walls. As a result, the storage volume of the door rack 6 as such can be increased.

In FIG. 3, the arrangement according to FIG. 2 is shown in a perspective sectional illustration. The cutting plane is in the y-z plane. As can be seen here, the cavity 11 extends in the horizontal plane and thus the xz-plane over the entire dimensions of the floor 10. In this context, the floor plate 11 has a dimension which, when viewed as a projection onto the door rack 6 from above ( in the negative y-direction) corresponds in area to the dimensions of the bottom 10.

As can also be seen, the cavity 11 is delimited towards the front by a further delimiting wall or front wall 18. On the back and thus facing the inner wall 5 of the door 4, the cavity 11 is designed to be open, a light coupling opening 19 being formed here. This is formed in particular over the entire width of the trough-like container 7. A flat shaft 12 is formed by the base 10, the base plate 13, the boundary walls 14 and the front wall 18.

As can also be seen, the bottom plate 13 preferably extends in the depth direction over the corresponding dimensions as the tub-like container 7, so that in the assembled state of the door rack 6 on the inner wall 5, a rear edge 20 of this bottom plate 13 rests against the inner wall 5 . Accordingly, in In an advantageous embodiment, the rear side of the base 10 also adjoins the inner wall 5. Such a configuration achieves on the one hand an even more stable positioning of the door rack 6 on the inner wall 5, on the other hand the inner wall 5 of the door 4 then also forms a boundary wall for the cavity 11 over the entire width in this rear area.

In addition, it can be seen that in the advantageous exemplary embodiment shown here, the cavity 11 tapers towards the front, starting from the rear end which faces away from the front wall 15. The cavity 11 designed as a shaft is thus narrower from its light coupling opening 19 to the front boundary wall 18.

In addition, it can also be seen in FIG. 3 that a lighting device 21 is arranged on the inner wall 5. The lighting device 21 is thus arranged externally to the door rack 6. In an advantageous embodiment, it is positioned here in such a way that the light emitted by the lighting device 21 is coupled or irradiated directly into the cavity 11 via the light coupling opening 19. In this context, it can be provided in an advantageous embodiment that the inner wall 5 has a cover 22 that is formed at least in regions. This cover 22 can be designed to be transparent, in particular in the area of the lighting device 21, so that light emitted by the lighting device 21 can be radiated through the transparent area 23 into the cavity 11. As a result, the lighting device 21 is arranged in a particularly protected manner. Even when the door rack 6 is removed, the lighting device 21 is not completely exposed.

The lighting device 21 can have one or more light sources, in particular one or more light-emitting diodes. It can be provided that the lighting device 21 radiates the light into the cavity 11 via the light inlet opening or light coupling opening 19 via individual irradiation areas or irradiates in strips over at least a partial area of this light coupling opening 19.

In FIG. 4, the illustration in FIG. 3 is shown in the sectional plane. It can be seen here that the light L emitted via the lighting device 21 via the rear Light coupling opening 19 is radiated into the cavity 11, is scattered there in a targeted manner, namely via the floor 10 upwards into the inner volume 9 of the tub-like container 7 and in particular at the same time downwards through the base plate 13 out of the door rack 6.

In FIG. 5, a partial section of the door 4 in the area of the lighting device 21 is shown. A view of a rear side 24 of the inner wall 5 facing the interior is shown here, to which the strip-like lighting device 21 is attached. In particular, a plurality of holding elements 25 are provided here, which are preferably formed in one piece on this inner wall 5 and which hold the lighting device 21.

In Fig. 6, a further embodiment of a household refrigerator 1 is shown in a partial representation. In this embodiment, which can also be implemented in the embodiments according to FIGS. 1 to 4, the domestic refrigeration appliance 1 has a first accommodation space for food, which is formed by the accommodation space 3. This can in particular be a cooling compartment. In addition, the domestic refrigeration appliance 1 has a further receiving space for foodstuffs which is separate for this purpose, which space is referred to here as receiving space 26 and which can be a freezer compartment. As can be seen here, the upper receiving space 3 in the vertical direction is closed by two separate doors 27 and 28. These two doors 27 and 28 are arranged next to one another in the width direction and positioned in the height direction virtually at the same height. The further receiving space 26 can be closed by a separate door 29. This door 29 can be a front wall of a drawer which can be pushed in and pulled out in the linear direction and in the depth direction. In the closed state, the doors 27, 28 and 29 are arranged in the same plane as one another and represent visible components or external parts of the domestic refrigeration appliance 1 on the front.

The doors 27 and 28 can be operated independently of one another, so that either both doors 27 and 28 can be pivoted via vertical axes in each case or only one of them is operated accordingly. As already explained above, such a configuration with accommodation spaces and a number of doors relating to this can also be provided in the examples in FIGS. 1 to 4.

In the exemplary embodiment in FIG. 6, a further advantageous embodiment provides that the door 27 or 28 is designed individually. In this further exemplary embodiment, the door 28 is designed accordingly and designed as a door device 30. In this context, this door device 30 has in particular a first door 31 (FIGS. 7 and 8) and also has a second door 32 for this purpose. The two doors 31 and 32 are each their own physical components, which in particular can be pivoted about a common vertical axis. The two doors 31 and 32 can also be pivoted independently of one another and thus individually. In this context, the second door 32 represents the front component and, in the closed state, covers the first door 31 located behind it in the depth direction. If the two doors 31 and 32 are coupled to one another, they are also coupled in terms of movement in this regard. This means that the entire door device 30 can then be pivoted together about a vertical axis. This also gives access to the receiving space 3. If, on the other hand, only the front second door 32 of this door device 30 is actuated and thus pivoted, access to a storage room 33 can be achieved. This storage space 33 is thus formed in the door device 30 itself. It can for example be designed as a bottle storage room. This storage space 33 is thus arranged between the first door 31 and the second door 32 and is thus delimited by the two doors 31 and 32 when the door device 30 is closed. The storage room 33 is open to the front so that it is accessible from the front when the second door 32 is open. This can be achieved both when the first door 31 is closed and when the first door 31 is also open.

As can also be seen in FIG. 7, the storage space 33 is delimited in an advantageous embodiment by a separate insert 34 at least to the side, to the rear, to the top and to the bottom. This insert 34 is therefore designed like a trough. It is shown with the lower door rack 6 in FIG. 7, which shows a cut perspective illustration in which the cutting plane is in the horizontal plane and is thus in the xz plane. In addition, it can also be seen in FIG. 7 that a further door rack 36 in this regard is arranged on an inside of the first door 31 facing the receiving space 3. This further door rack 36 can be a conventional door rack and, when the first door 31 is closed, is not accessible from the outside and therefore not accessible from the front. The door rack 6 differs from such an embodiment of a door rack 36 in accordance with the representations set out above, in particular with regard to the explanations relating to FIGS. 2 and 4.

In FIG. 7, the second door 32 is shown in the open state, so that access to the storage room 33 is made possible from the front. The first door 31 is still closed, however, so that access to the receiving space 3 is blocked.

As can be seen here, the second door 32 has a configuration that is at least partially transparent. To this end, in the exemplary embodiment shown, viewing panes 37 are provided through which the door 32 can be viewed when the door is closed. In this connection, the second door 32 also has a frame 38 which surrounds this at least one pane 37, preferably a pane of panes, which can also be insulating glass.

In FIG. 8, the household refrigerator 1 according to FIGS. 6 and 7 is shown in the area of the door device 30 in a perspective vertical section. A state is shown here in which the second door 32 is also shown in the closed state. The door device 30, which is also designed as a door-open-door system, thus also enables the second door 32 to be opened when the first door 31 is closed, thus allowing only access to the storage room 33. If access to the receiving space 3 is to be achieved, the entire door device 30 and thus the movement-coupled doors 31 and 32 are pivoted so that access to these inner door racks 36 is then also given.
