Description

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.

To improve this, for example, from the WO 2005/024323 A1 a door rack known that 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 holding 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. The cavity is thus When viewed as a projection onto the door rack, viewed from above, the surface area is the same as the floor or essentially 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 then also possible to be able to reach into the cavity, for example in order 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 individually on the door itself is positioned. 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 in such a way 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 light can be radiated into the cavity particularly advantageously and extensively, so that the light would not exit downwards via a shortened base plate between a gap between the rear edge of the base plate and the inner wall of the door, especially with a lighting device external to the door compartment. On the other hand, this embodiment 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.

A further aspect of the invention relates to a door device with a first door according to the above-mentioned aspect or an advantageous embodiment thereof and with a second door which is separate therefrom, which is pivotably arranged on the first door and which, when closed, covers the first door at least in some areas at the front, wherein the second door is 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 therefore also pivoted when the entire door device is pivoted relative to the housing of the domestic refrigeration appliance, in particular in order to obtain access to the receiving space.

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

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

In 1 is a schematic representation of an embodiment of a household refrigerator 1 shown, which can be, for example, a refrigerator or a freezer or a combined fridge-freezer. The household refrigerator 1 , which is designed for storing and preserving food, has a housing 2 on, in which at least one recording room 3 is trained for food. The recording room 3 is preferably a cooling compartment.

In addition, the household refrigerator 1 a door 4th on, which is pivotable on the housing 2 is arranged. The door 4th is to close the front of the recording area 3 educated. The door 4th has an inner wall 5 on that when the door is closed 4th the recording room 3 is facing. On this inner wall 5 is at least a door rack 6th arranged. The door rack 6th is designed to accommodate food and is preferably designed in its basic geometry as an elongated cuboid.

In 2 is the door in a simplified representation 4th with an embodiment of a door rack arranged thereon 6th shown. The door rack 6th has a tub-like container 7th on, which is formed in one piece from plastic. The tub-like container 7th is open at the top, so that a receiving volume 8th is accessible from above. This tub-like container 7th has a peripheral border 9 on that to a floor 10 flows out. In addition, the tub-like container 7th a cavity 11 on, which is designed for light coupling and scattering of the coupled light. The cavity is seen in the height direction (y-direction) below the floor 10 directly to the ground 10 subsequently trained. The cavity 11 is integrated and in one piece with the tub-like container 7th educated. The cavity is viewed in the vertical direction upwards 11 through the ground 10 directly limited. Down is the cavity 11 through a separate base plate 13 that lead to the floor 10 is separate, limited. The bottom plate 13 is offset downwards in height and at a distance from the ground 10 educated. The cavity is also to the side 11 limited, with lateral boundary walls viewed here in the width direction (x-direction) 14th are provided.

In addition, the door rack 6th In the embodiment shown, an additional, separate front wall 15th on. As can be seen, the front wall extends over the entire width of the container 7th . The front wall is viewed in the vertical direction 15th over the edge 9 of the container 7th protruding upward, in particular protruding significantly upward, formed.

On retaining elements 16 and 17th that is on the front wall 15th are arranged, further side walls, not shown here, can be attached, which for example also have the same height as the front wall 15th can have. This is the tub-like container 7th Additionally edged on the front and on the side walls. This can reduce the storage volume of the door rack 6th as such are enlarged.

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

As can also be seen, the cavity is 11 towards the front through another boundary wall or front wall 18th limited. On the back and thus the inner wall 5 the door 4th facing is the cavity 11 open, with a light coupling opening here 19th is trained. This is in particular over the entire width of the tub-like container 7th educated. Through the ground 10 who have favourited the bottom plate 13 , the boundary walls 14th and the front wall 18th is a shallow shaft 12 educated.

As can also be seen, the base plate extends 13 in the depth direction, preferably over the corresponding dimensions as the tub-like container 7th so that in the assembled state of the door rack 6th on the inside wall 5 a rear edge 20th this floor slab 13 on the inside wall 5 is applied. Correspondingly, in an advantageous embodiment, the back of the floor is also located 10 on the inside wall 5 on. Such a configuration, on the one hand, results in an even more stable positioning of the door rack 6th on the inside wall 5 reached, on the other hand then also forms the inner wall 5 the door 4th a boundary wall for the cavity 11 across the entire width in this rear area.

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

In addition, in 3 can also be seen on the inside wall 5 a lighting device 21st is arranged. The lighting device 21st is therefore external to the door rack 6th arranged. In an advantageous embodiment, it is positioned here so that that of the lighting device 21st emitted light directly through the light coupling opening 19th into the cavity 11 is coupled or irradiated. In this context, it can be provided in an advantageous embodiment that the inner wall 5 an at least regionally designed cover 22nd having. This cover 22nd can in particular in the area of the lighting device 21st be made transparent, so that of the lighting device 21st light emitted through the transparent area 23 into the cavity 11 is irradiated. This is the lighting device 21st arranged in a particularly protected manner. Even if the door rack 6th is removed, the lighting device is 21st not completely free.

The lighting device 21st can have one or more light sources, in particular one or more light-emitting diodes. It can be provided that the lighting device 21st The light enters the cavity via individual radiation areas 11 via the light inlet opening or light coupling opening 19th irradiates or stripes over at least a portion of this light coupling opening 19th irradiates.

In 4th is the representation in 3 shown in the cutting plane. It can be seen here that the light L. , which is about the lighting device 21st via the light coupling opening on the back 19th into the cavity 11 is irradiated, is scattered there specifically, namely over the ground 10 up into the interior volume 9 of the tub-like container 7th and in particular at the same time downwards through the base plate 13 from the door rack 6th out.

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

In 6th is a partial representation of a further embodiment of a household refrigerator 1 shown. In this embodiment, which is also the case in the statements according to 1 to 4th can be realized, has the household refrigerator 1 a first receiving space for food, which is through the receiving space 3 is formed. This can in particular be a cooling compartment. In addition, the household refrigerator 1 a separate additional receiving space for food, here as Recording room 26th and which can be a freezer compartment. As can be seen here, the upper receiving space in the vertical direction is 3 through two separate doors 27 and 28 locked. These two doors 27 and 28 are arranged next to each other in the width direction and positioned in the height direction almost at the same height. The further recording room 26th is through a separate door 29 lockable. 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. The doors are closed 27 , 28 and 29 arranged in the same plane to each other and represent front visible components or external parts of the household refrigerator 1 represent.

The doors 27 and 28 can be operated independently of each other so that either both doors 27 and 28 can be pivoted via vertical axes or only one of them is operated accordingly.

As already explained above, such a configuration with accommodation spaces and related multiple doors can also be used in the examples in 1 to 4th be provided.

In the embodiment in 6th is provided in a further advantageous embodiment that the door 27 or 28 is individually trained. Here is the door 28 in this further embodiment designed accordingly and as a door device 30th educated. This door device 30th in this context has in particular a first door 31 ( 7th and 8th ) and also has a second door 32 on. The two doors 31 and 32 are each separate objective components, which can be pivoted in particular about a common vertical axis. The two doors 31 and 32 can also be pivoted independently of one another and thus individually. The second door 32 In this context, it represents the front component and, when closed, covers the first door behind it in the depth direction 31 from. Are the two doors 31 and 32 coupled to one another, they are also movement-coupled in this regard. This means that the entire door device 30th can then be pivoted together about a vertical axis. This also gives access to the recording room 3 reached. On the other hand, only the front second door is used 32 this door device 30th actuated and thus pivoted, can access a storage room 33 can be achieved. This storage room 33 is thus in the door device 30th self trained. It can for example be designed as a bottle storage room. So this storage room is 33 between the first door 31 and the second door 32 arranged and thus in the closed state of the door device 30th through the two doors 31 and 32 limited. The lumber 33 is open at the front so that it can be opened when the second door is open 32 accessible from the front. This can be achieved both when the first door 31 is closed as well as when the first door 31 is also open.

As in 7th can be seen is the storage room 33 in an advantageous embodiment through a separate insert 34 at least to the side, to the rear, to the top and bottom. This use 34 is therefore designed like a tub. He is in 7th which shows a cut perspective view in which the cutting plane is in the horizontal plane and is therefore in the xz plane, with the lower door rack 6th shown.

In addition, in 7th also to see that on one of the recording room 3 facing inside of the first door 31 another door rack in this regard 36 is arranged. This further door rack 36 can be a conventional door rack and is in the closed state of the first door 31 from the outside and therefore not accessible from the front. From such an embodiment of a door rack 36 the door rack differs 6th in accordance with the representations set out above, in particular with regard to the explanations 2 and 4th .

In 7th is the second door 32 shown in the open state, so that the front access to the storage room 33 is made possible. The first door 31 however, it is still closed, allowing access to the recording room 3 is kept.

As can be seen here, the second door has 32 an embodiment that is at least partially transparent. For this purpose, there are viewing panes in the embodiment shown 37 provided by which in the closed state of the door 32 can be looked through. The second door 32 also has a framework in this context 38 on that at least one slice 37 , preferably a pane package, which can also be an insulating glass, surrounds the circumference.

In 8th is a perspective vertical sectional view of the household refrigerator 1 according to 6th and 7th in the area of the door device 30th shown. A state is shown here in which the second door 32 is shown in the closed state. The door device 30th , which is also designed as a door-open-door system, thus also enables the first door to be in the closed state 31 the second door 32 can be opened and therefore only access to the storage room 33 is made possible. Should have access to the recording room 3 can be achieved, the entire door device 30th and thus the motion-coupled doors 31 and 32 pivoted, so that there is also access to these inner door racks 36 given is.
