Description

Domestic refrigerator having an inner container and a light source module arranged thereon having a special light exit edge

Technical Field

One aspect of the invention relates to a domestic refrigeration appliance comprising an inner container which delimits with a wall at least one receiving space for food products of the domestic refrigeration appliance. The domestic refrigerator also has at least one light source module which is arranged on a wall of the interior container and emits light into the receiving space. The light source module has a transparent cover through which light of a light source of the light source module is emitted from the light source module.

Background

Such a domestic refrigerator is known, for example, from document EP 2 594 880 B1. There, the cover is designed as an angled element. The fold of the cover (which is oriented parallel to the wall of the inner container) is of opaque design. The second fold of the angled cover is arranged obliquely to the wall of the inner container and is oriented toward the rear wall of the inner container. This makes it possible to emit light from the light source of the light source module only through the large-area outer side of the second fold and thus only in the direction of the inner container rear wall. The edge edges of the folds are arranged covered.

In such a solution, the light radiation is only conditionally suitable, in particular also in the front region, for illuminating the receiving space. Furthermore, it is not possible to achieve by radiating over only a very large area over the entire bend: a discrete center of gravity for the light (lichtakzene) may be provided. In particular, the illumination scene is therefore limited in the prior art and is relatively weak with regard to the illumination of the receiving space.

Disclosure of Invention

The object of the present invention is to provide a domestic refrigerator in which the light emission of a light source module, which is arranged on the wall of the interior container, is improved.

This object is achieved by a domestic refrigeration device having the features of claim 1.

One aspect of the invention relates to a domestic refrigeration appliance comprising an inner container. The inner container has a wall. At least one receiving space for food items of the domestic refrigeration device is delimited by the walls. Such a receiving space may be, for example, a freezer compartment or a refrigerator compartment. The domestic refrigerator also has at least one light source module. The light source module is arranged on a wall of the interior container separate therefrom. The light source module is positioned such that the light source module conventionally emits light into the accommodating space. The light source module has a transparent cover through which light of the light source module is emitted from the light source module into the accommodation space. The cover is in particular designed as a plate-like strip. The cover has a front face facing the receiving space. Furthermore, the cover has a narrow strip-shaped edge. The strip-shaped edge in particular also delimits the covering element. The strip-shaped edge is arranged in particular at an angle to the front face. The front face is larger than the strip-shaped edge, in particular very large, in terms of area. The edge is arranged, at least viewed in the width direction of the domestic refrigeration appliance, exposed to the receiving space. The edge is conventionally the light exit edge of the light source module, from which the light of the light source can be radiated or emitted during operation of the light source module. In particular, it is provided that the light is emitted at least partially forward from the light source module via the light exit edge. This means that, viewed in the depth direction of the domestic refrigeration appliance, the light emitted from the light exit edge is emitted at least partially towards the filling opening of the inner container. This makes it possible to achieve an improved illumination of the receiving space, at least also in the front region or toward the filling opening. It is in this connection that a more individual and improved optical signaling effect can also be produced by such a narrow light exit edge. In this way, a narrow light strip or light strip can be produced, which can also be perceived by the user when looking at the filling opening. A very individual light center of gravity can thus be generated in the receiving space, in particular in the front region of the receiving space.

The light exit edge is in particular an edge which also determines the thickness of the cover. The light exit edge is thus the connection surface between the front and rear side of the cover. The rear side of the cover part faces the light source of the light source module or the interior of the housing of the light source module. The front side of the light source module is preferably as large as five times, in particular at least ten times, the area of the light exit edge. The light exit edge is in particular a very narrow planar strip. The planar strip is in particular formed as a quadrilateral. The two opposite bounding edges of the surface of the light exit edge are several times, in particular at least 10 times, in particular at least 20 times, larger than the two other, shorter, opposite bounding edges. It can be provided that the shorter delimiting edge has a length of between 0.3cm and 3 cm.

In addition, this makes it possible to see a correspondingly narrow light strip when the light source module is activated, if the user observes in the receiving space. A very individualized optically illuminated scene of the receiving space towards the filling opening can thus be achieved. In particular, a very high illumination of the light can also be achieved in one embodiment in this connection, since a correspondingly higher light emission can also be achieved by the narrow light exit edge.

In addition, in one embodiment it is also possible to achieve that the light of the light source can also be radiated through the front face in addition to the light exit edge. In this connection, the light can also be radiated back into the receiving space over a larger area. The front surface extends in a plane which is oriented at an angle of more than 0 °, in particular more than 30 ° and less than 120 °, to the plane in which the light exit edge extends.

It can be provided that the plane in which the light exit edge extends in a planar manner is extended in the depth direction and in the height direction of the domestic refrigerator. The plane of the light exit edge can also be arranged at an angle to a vertical plane which extends in the depth direction and in the height direction of the domestic refrigeration appliance. In particular, the plane of the light exit edge can be arranged in a manner inclined forward toward the filling opening. A sharp internal angle can be formed between this vertical plane and the plane of the light exit edge. This in turn improves the light radiation from the light exit edge in the direction of the filling opening.

In one embodiment, the rim edge is oriented obliquely and faces the filling opening on the front side of the inner container, wherein the rim edge forms the front end of the cover. The edge can be arranged at an angle to a wall region in the plane of extension thereof, which wall region, in particular, as viewed in the depth direction, adjoins the edge forward. It is also possible for the plane in which the edge extends to be oriented parallel to the plane of the wall region of the wall which adjoins the edge forward.

In one embodiment, the cover is a diffuser plate. The cover may also be referred to as a diffuser plate (streupllate). Accordingly, light of at least one light source of the light source module is scattered correspondingly by the diffuser plate. Thereby, a uniform light radiation with a homogeneous light pattern can be achieved.

In one embodiment, the cover can also have a light guide structure, through which the light of at least one light source of the light source module can be guided in a targeted manner to the light exit edge. In particular, it is provided that the structure is arranged in the cover such that the light deflection defined in this connection is carried out in the cover towards the light exit edge. This makes it possible to increase the portion of the light emitted from the light exit edge in a personalized manner. This enables a particularly intense emission of light from the light exit edge.

In one embodiment, the cover is oriented at an angle to a vertical plane of the domestic refrigeration appliance. The vertical plane extends in the depth direction and in the height direction of the domestic refrigeration appliance. In particular, a front end of the cover in the depth direction of the domestic refrigeration appliance is arranged further inwards than a rear end of the cover, viewed in the width direction of the domestic refrigeration appliance. This means that the front end of the cover projects further into the receiving space than the rear end. The illumination can be improved in a particularly advantageous manner by such a tilting of the cover. The orientation associated therewith already assists in principle in the desired light radiation, in particular at least partially toward the front from the light exit edge. In addition, the preferably possible light radiation through the front side to the rear side is also correspondingly assisted. Since the front side is also exposed toward the receiving space, a correspondingly targeted light radiation into the rear region of the receiving space can then also be achieved here.

In one embodiment, the light source module has a housing on which the cover is arranged. The cover may be a separate component from the housing. In one embodiment, the cover and the housing can also be produced in one piece.

In one embodiment, the cover is constructed of plastic. However, the cover can also consist of pure glass. In one embodiment, the cover is constructed in one piece. The cover is in particular transparent. This means that the cover is transparent for light in the spectral range visible to humans.

In one embodiment, the housing has an inner housing wall viewed in the width direction of the domestic refrigeration appliance. The front side of the inner housing wall is arranged to extend further inward than the front end of the cover as viewed in the width direction. The inner housing wall is therefore arranged closer to the receiving space, or further into the receiving space, as viewed in the width direction, than the outer housing wall of the housing, as viewed in the width direction. In the receiving space, the front side (which faces away from the housing interior of the light source module) is arranged more interior in the width direction than the front end in the receiving space, a certain glare protection (blendshutz) for the observer is also achieved. Due to the projection of the front side relative to the front end of the cladding element (which is formed by the light exit edge) which is produced in the width direction in this connection, a certain impact protection is also achieved, so that the light exit edge is also protected in this connection. The projection of the front side with respect to the light exit edge can be between 1mm and 5mm, viewed in the width direction.

In one embodiment, the housing of the light source module has an outer housing wall viewed in the width direction of the domestic refrigeration appliance. In one embodiment, the outer housing wall has a receptacle in which the rear end of the cover is arranged. In one embodiment, the receptacle is a wall thinning of the outer housing wall (Wandverd unnung). Thereby, the rear end of the cover overlaps with the outer housing wall in a state arranged in connection therewith on the housing. A correspondingly advantageous positioning and mechanically fixed fitting (Sitz) of the cover on the housing at its rear end can thereby be achieved. Further, with this configuration, the rear end portion of the cover is not exposed, but is covered by the outer case wall. In particular, complete coverage is formed here.

In one embodiment, the cover has at least one snap-in element on an inner side facing the housing, which snap-in element is in snap-connection with at least one mating snap-in element on a housing of the light source module separate therefrom. Such a mechanical coupling between the two separate components can be produced mechanically functionally highly simple and user-friendly to assemble and disassemble. In one embodiment, the cover can be mounted by lateral displacement. In order to also enable disassembly in the mounted state of the light source module, it is provided in one embodiment that a space holder (Platzhalter) is arranged at the upper end in the height direction. The cover can thus also be removed from the housing very simply by a slight lifting in the upper region and a lateral movement upwards.

In one embodiment, the cover rests with the inner side facing the housing on the free edge of the inner housing wall. The free edge is the edge of the inner shell wall. A mechanically reliable and stable positioning is thereby also achieved. In one embodiment, the cover overlaps both the free edge of the inner housing wall and the free edge of the outer housing wall.

In one embodiment, the light exit edge of the cover is arranged, as viewed in the depth direction of the domestic refrigerator, directly on the front side of the inner housing wall of the housing. The front side is in this connection the side facing away from the housing interior and facing the receiving space. As a result, the front sides of the inner housing walls and the light exit edge are arranged in a row with respect to one another, as viewed in the depth direction of the domestic refrigeration appliance. The light exit edge is designed in the depth direction with a dimension that is significantly smaller than the extent of the front side in the depth direction. In particular, the front side is at least five times, in particular at least eight times, as long as the light exit edge.

In one embodiment, the cover is L-shaped as viewed in cross-section. The cover is, as mentioned above, in one embodiment an elongated plate or an elongated rail. In this connection, the covering element has a longitudinal axis along its longer dimension. The cross section can be considered in this connection as being perpendicular to the longitudinal axis. The first L branch edge of the L shape covers the opening of the shell. The second L limb of the L-shape is thus oriented convexly. The second L-leg is oriented away from the housing. The exposed end of the second L-limb facing away from the first L-limb forms the edge or light exit edge of the cladding element. With this embodiment, the light exit edge is arranged offset further outwards, viewed in the width direction, towards the adjacent wall of the inner container and further offset rearwards, viewed in the depth direction, from the housing of the light source module. This also makes it possible to implement a personalized light emission profile through the light exit edge.

In one embodiment, the housing is an elongated hollow rail. The hollow rail has a U-shaped cross-section. The cross section can also be understood as being perpendicular to the longitudinal axis of the elongate rail.

At least one light source, in particular a light-emitting diode, is arranged in the housing interior. A plurality of light-emitting diodes can also be arranged in connection with this. The corresponding electronics of the light source module may also be arranged in the housing.

In one embodiment, the wall of the inner container has a receiving recess on its inner side facing the receiving space, into which the light source module is inserted. The light source module is thereby arranged at least partially in a depression and does not protrude undesirably or protrude too far into the receiving space. The light source module may be more compactly positioned by such an embodiment. The light source module can thus also be mounted more mechanically stable and better protected against impact and the like.

In one embodiment, a housing wall of the housing facing the receiving space is arranged flush with a wall region of the wall adjoining the receiving recess forward. The light source module is thereby arranged sunk into the receiving recess, viewed approximately far in the width direction, such that no projection is present. This achieves the above-mentioned advantages in particular.

It is also possible that the covering is coloured. This also makes it possible to improve the perception of the light exit edge in the off state of the light source module. In particular, such coloring with a material then also makes it possible to achieve a personalized contrast with adjacent components, so that in the off state of the light source module the light exit edge also visually stands out in contrast with other adjacent components. It is also possible that the cover (when the cover is configured as a separate component from the housing of the light source module) is not connected to the housing only by a non-destructive releasable connection, for example at least one snap connection. Also a non-releasable connection can be provided here. For example, an adhesive or welding can be provided.

The housing and the cover can also be designed as a one-piece component, for example as a two-component plastic component. The light exit edge may also be formed only over a partial length of the entire light source module. In particular, the light exit edge is formed over the entire length of the light source module.

In the assembled state of the domestic refrigeration appliance, the outer side of the inner container can be covered with a heat insulating material, in particular polyurethane rigid foam.

The inner container can be made of plastic, in particular polystyrene, and can be produced by deep drawing or injection molding.

The descriptions "upper", "lower", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" give the positions and orientations given in the conventional use and conventional positioning of the appliance.

The features and feature combinations described in the description and/or shown in the figures can be used both in the combination stated in each case and also in other combinations or alone without departing from the scope of the invention.

Detailed Description

Fig. 1 shows an exemplary embodiment of a domestic refrigeration device 1 in a perspective view. The domestic refrigerator 1 is designed for storing and storing food. The domestic refrigerator 1 can be a refrigerator or freezer or a combination refrigerator-freezer.

The domestic refrigeration appliance 1 can be a stand-alone domestic refrigeration appliance or a built-in appliance.

The domestic refrigerator 1 has an outer housing 2. The domestic refrigerator 1 also has an inner container 3. The inner container is separated from the outer housing 2. The inner container 3 is received in the outer housing 2. An insulating material 5 is installed in the intermediate space 4 between the outer casing 2 and the inner container 3. Inner container 3 has walls 6, 7, 8, 9 and 10. These walls 6 to 10 delimit at least one receiving space 11 of the domestic refrigeration appliance 1. The receiving space 11 is conventionally provided for receiving food. The receiving space may be a refrigerating compartment or a freezing compartment. The domestic refrigeration appliance 1 also has a door 12. The door is movably arranged on a fuselage comprising an outer shell 2 and an inner container 3. The filling opening 13 on the front side of the inner container 3 can thereby be closed.

Furthermore, the domestic refrigeration device 1 has at least one light source module 14. The light source module is arranged on an inner side 9a of the wall 9 of the inner container 3 facing the receiving space 13. This position is to be understood as exemplary only. In addition or alternatively thereto, the light source module may also be arranged, for example, on the inner side of the wall 7 and/or on the inner side of the wall 8 and/or on the inner side of the wall 6.

As already indicated in fig. 1, the wall 9 is provided with a receiving recess 15 on the inner side 9 a. The blind-hole-like recess is provided for accommodating the light source module 14. The light source module 14 is thus arranged at least partially sunk in the wall 9.

Fig. 2 shows an enlarged view of a part of region I in fig. 1. It can be seen that the light source module 14 is configured here as an elongated rail. The longitudinal axis a of the elongate rail is oriented in the height direction (y direction) of the domestic refrigeration appliance 1. The receiving recess 15 is formed in the width direction (x direction) of the domestic refrigeration device 1 toward the side, so that in connection with this, the light source module 14 sinks into this receiving recess 15, viewed in the width direction.

The light source module 14 has a housing 16. In fig. 2, the inner housing wall 17 is visible in this connection. Which in an embodiment is exposed towards the receiving space 11. In particular, the inner housing wall 17 has a front side 17a. The front side is the visible side (sichtsei) facing the receiving space 11. The inner housing wall 17 is designed here as a plate-like strip. Furthermore, the housing 16 (as can be seen in the perspective sectional view in fig. 3) has an outer housing wall 18. The outer case wall 18 is disposed farther from the accommodation space 11 than the inner case wall 17 as viewed in the width direction. Furthermore, the housing 16 has a connecting wall 19. The connecting wall 19 is provided for connecting the inner housing wall 17 with the outer housing wall 18.

In this embodiment, the cross-section of the housing 16 is U-shaped when viewed perpendicular to the longitudinal axis a.

At least one light source 21 is disposed in the interior 20 of the housing 16. The light source 21 may comprise a light emitting diode. Furthermore, the electronics of the light source module 14 may also be arranged in the interior 20. As can also be seen in fig. 3, the light source module 16 has a cover 22. The cover 22 is at least partially transparent. The covering 22 is designed here as an elongated strip. The plate associated therewith has a front face 23. The front face 23 faces away from the interior 20. The front face 23 faces the accommodation space 11. The front face 23 is exposed toward the accommodating space 13. The front face 23 is a large-area front side with respect to the strip-shaped plate. In contrast, the cover 22 also has a back 24. The back surface 24 faces the front surface 23. The back face 24 faces the interior 20. As provided in the plate-like configuration of the component, the cover 22 also has an edge 25. The edge 25 is the narrow side of the cover 22. The edge 25 is here conventionally and functionally designed as a light exit edge 26. This means that, definitively and desirably, the light of the light source 21 is conventionally emitted from this edge 25, which forms the light exit edge 26. As can be seen, the light exit edge 26 is a narrow strip area. The strip area is smaller than the large area of the front face 23 and/or the large area of the back face 24, in particular very small. The light exit edge 26 extends with its surface facing the receiving space 11. The light exit edge 26 is exposed, in particular completely exposed, to the receiving space 11. The light exit edge 26 can extend in a plane which is formed by the height direction and the depth direction (z direction) of the domestic refrigerator 1. However, the plane in which the light exit edge 26 extends in a planar manner may also be arranged at an angle to the plane running through the height direction and the depth direction of the domestic refrigeration appliance 1. In particular, in such an embodiment, the plane of the light exit edge 26 can be arranged at an acute angle to the vertical plane and is oriented at the acute angle to the filling opening 13. The light exit edge 26 conventionally emits light at least partially also in the forward direction into the front region of the receiving space 11, in particular also toward the filling opening 13. The light exit edge 26 is arranged completely exposed to the receiving space 11.

The light exit edge 26 is here a vertical planar strip.

Furthermore, the cover 22 has a further opposite edge 27. The other edge 27 faces the wall 9. The other edge 27 is not designed and arranged for light emission. In this exemplary embodiment, it is provided that the edge 25 and thus the light exit edge 26 are oriented obliquely. The edge 25 forms the front end 28 of the cover 22, viewed in the depth direction. The cover 22 is in particular designed as a diffuser plate or as a diffuser plate.

As can also be seen in fig. 3, the cover 22 is oriented with its plate-like elements at an angle to the vertical plane. In particular, a front end 28 of the cover 22 in the depth direction of the household refrigeration appliance 1 is arranged offset further inward toward the receiving space 11, viewed in the width direction of the household refrigeration appliance 1, than a rear end 29 of the cover 22, viewed in the depth direction. The rear end 29 is formed in particular by the outer edge 27.

In one embodiment, it can be provided that, viewed in the width direction, the front side 17a of the inner housing wall 17 is arranged offset further into the receiving space 11 than the front end 28 of the cover 22. In particular, a corresponding offset in the width direction between the front side 17a and the light exit edge 26 is also formed in this connection. However, it is also possible in one embodiment for the light exit edge 26 to be arranged at the same width position in the width direction as the front side 17a. In particular, it is provided that the plane of the front side 17a and the plane of the light exit edge 26 each extend in a common plane or in planes parallel to one another.

In contrast, in a further exemplary embodiment, as described above, the plane in which the light exit edge 26 extends can also be arranged at an angle to the vertical plane. This plane is thus also oriented at an angle with respect to the front side 17a. In particular, the light exit edge 26 is then oriented obliquely to the filling opening 13.

In one exemplary embodiment, the housing wall 18 has a receptacle 30. A rear or outer end 29 of the cover 22 extends into the receptacle 30. In this exemplary embodiment, the receptacle 30 is formed by an end region of the outer housing wall 18 that is reduced in thickness. As can be seen, the outer edge 27 is completely covered by the receptacle 30.

Furthermore, it can also be seen in fig. 3 that the cover 22 projects beyond the free end 31 of the inner housing wall 17, viewed in the width direction, and thus covers this free end 31 at least in places.

It can also be seen that the cover 22 has at least one snap-in element 32. Which snap-fit connection with at least one counterpart snap-fit element arranged on the housing 16. Preferably a plurality of snap elements and mating snap elements are provided. Fig. 3 also shows that the inner side or rear side 24 of the cover 22 rests against a free end or edge 31 of the inner housing wall 17. Furthermore, it can also be seen in fig. 3 that, viewed in the depth direction of the domestic refrigerator 1, the edge 25 and thus the light exit edge 26 are arranged directly adjacent to the front side 17a of the inner housing wall 17.

The arrangement of the components in fig. 3 is shown in a sectional plane in fig. 4. Fig. 4 shows a sectional or horizontal sectional plane, which differs from fig. 3 in this respect. In fig. 4, it can also be seen here that the housing 16 has a coupling 33. The coupling piece projects through a recess 34 in the wall 9, in particular in the receiving recess 15. The coupling piece 33 thus projects into the intermediate space 4. In one embodiment, a separate insert (hinderlegteil) or fitting 35 is arranged in the intermediate space 4. Thereby, the light source module 14 can be fixed to the fitting 35.

Fig. 5 shows a further exemplary embodiment of a domestic refrigeration device 1 in a perspective sectional view. A detail is shown here, in which the wall 7 of the inner container 3 is shown. In this exemplary embodiment, the cover 22 is not completely flat with the front plate, but rather the front plate is angled in this connection. In this case, the front face 23 is thus not flat, in particular angled. In this exemplary embodiment, it is also provided that the surface of the light exit edge 26 is planar in the vertical plane (which extends in the depth direction and in the height direction)

And is extended. In this case, in this embodiment, a flush arrangement with the front side 17a is realized, so that in particular the plane of the front side 17a is identical to the plane of the light exit edge 26.

Fig. 6 shows a further exemplary embodiment, which is implemented corresponding to the illustration in fig. 5. The difference from the exemplary embodiment in fig. 5 is that the light exit edge 26 is arranged here in the width direction by a projection offset further into the receiving space 11 than the front side 17a. This forms a further light exit edge 36 which projects in the width direction beyond the front side 17a. The further light exit edge 36 is therefore completely exposed forward, viewed in the depth direction. The plane of the further light exit edge 36 can be extended in the width direction and in the height direction. It may also be provided that the plane in which the further light exit edge extends or widens in a planar manner is arranged at an angle to the vertical plane.

Fig. 7 shows a further exemplary embodiment of the domestic refrigeration device 1 in a perspective view corresponding to fig. 5 and 6. In this exemplary embodiment, further configurations of the cover 22 are provided. The light exit edge 26 is arranged here, as viewed in the depth direction, not directly adjoining the front side 17a of the inner housing wall 17. But here the cover 22 is L-shaped as seen in cross section. The first L-leg 37 is arranged in such a way that the first L-leg 37 rests against the housing 16 or closes or covers the opening of the housing 16. In this exemplary embodiment, the L-branch 37 does not have a thin light exit edge that would be exposed. The cover 22 has a second L-edge 38. The second L-leg 38 projects at an angle from the first L-leg 37, in particular projects away from the housing 16. The exposed end 39 of the second limb 38 has an edge 25 and thus a light exit edge 26. The light exit edge is inclined.

It is also possible in one embodiment to realize a combination of a cover 22 as shown in fig. 5 and 6 with a cover according to fig. 7. This covering 22 also has a laterally or forwardly exposed light exit edge 26 or 36, which is designed to engage directly behind the front side 17a, as viewed in the depth direction.

As can also be seen in the exemplary embodiments, as described above, a flush arrangement between the front side 17a and the wall region of the wall 7 or 9 which adjoins forwards in the depth direction is preferably provided. The wall regions 40 (fig. 3) and 41 (fig. 5 to 7) are correspondingly shown.
