HOUSEHOLD REFRIGERATING APPLIANCE WITH AN INNER CONTAINER AND A LIGHT SOURCE MODULE ARRANGED THEREON, WHICH HAS A SPECIFIC LIGHT EMITTING EDGE

Description

[0001] One aspect of the invention relates to a household refrigeration appliance with an inner container, which, with walls, defines at least one food storage space of the household refrigeration appliance. The household refrigeration appliance further comprises at least one light source module arranged on a wall of the inner container and emitting light into the storage space. The light source module has a transparent cover through which light from a light source of the light source module is emitted from the light source module.

[0002] Such a household refrigeration appliance is known, for example, from EP 2 594 880 B1. There, the cover is designed as an angled element. One angled part of this cover, which is oriented parallel to the wall of the inner container, is not transparent. A second angled part of this angled cover is arranged at an angle to this wall of the inner container and oriented towards the rear wall of the inner container. As a result, light from a light source of the light source module can only be emitted via the large-area outer surface of this second angled part and thus only radiated in the direction of the rear wall of the inner container. The edges of the angled parts are arranged in a covered manner.

[0003] WO 2022 / 108246 A1 discloses a refrigerator with a light source and a cover having a translucent area through which the light emitted by the light source passes, and an opaque area that prevents a clear view of the interior behind the cover. The edges of the translucent cover are covered.

[0004] JP 5 197172 B2 discloses a refrigerator with a light source and a translucent cover through which the light emitted by the light source passes. A metal foil can be applied to the translucent cover in certain areas to prevent light penetration. The edges of the translucent cover are covered.

[0005] With such a concept, the light emission is only partially suitable for illuminating the recording space, especially in the front area. Furthermore, only a very large area of radiation across this entire angled section makes it impossible to create discreet lighting accents. Therefore, the lighting scenario in the state of the art is particularly limited and relatively weak in terms of illuminating the recording space.

[0006] It is an object of the present invention to provide a household refrigeration appliance in which the radiation of light from a light source module arranged on a wall of an inner container is improved.

[0007] This object is achieved by a household refrigeration appliance having the features of claim 1.

[0008] One aspect of the invention relates to a household refrigeration appliance with an inner container. The inner container has walls. At least one receiving space for food of the household refrigeration appliance is delimited by these walls. Such a receiving space can be, for example, a freezer compartment or a refrigerator compartment. The household refrigeration appliance furthermore has at least one light source module. This is arranged on a wall of the separate inner container. It is positioned such that it emits light into the receiving space as intended. The light source module has a cover through which light from a light source of the light source module is emitted from the light source module into the receiving space. The cover is designed in particular as a plate-like strip. This cover has a front surface that faces the receiving space. Furthermore, the cover has a narrow, strip-shaped edge.This strip-shaped edge also delimits the cover. This strip-shaped edge is arranged at an angle to the front surface. In terms of area, the front surface is larger, in particular much larger, than the strip-shaped edge. The edge is arranged exposed towards the receiving space, at least when viewed in the width direction of the household refrigeration appliance. This edge is intended to be a light exit edge of the light source module, from which light from the light source can be radiated or emitted during operation of the light source module. In particular, it is provided that light is emitted at least partially forwards from the light source module through this light exit edge. This means that, viewed in the depth direction of the household refrigeration appliance, the light emerging from this light exit edge is emitted at least partially towards a loading opening of the inner container.According to the invention, a narrow light band or strip of light is created, which can also be perceived by a user when viewing the loading opening. Such a concept makes it possible to improve the illumination of the receiving space, at least in the front area or toward the loading opening. Such a narrow light exit edge in particular also allows for more individual and improved optical signaling effects to be generated. Highly individual lighting accents can therefore be created in the receiving space, especially in the front area of the receiving space.

[0009] This light exit edge is, in particular, the edge that also determines the thickness of the cover. This light exit edge is thus the connecting surface between the front surface and a rear surface of the cover. In this context, the rear surface of the cover faces the light source of the light source module or faces the interior of a housing of the light source module. A front surface of the light source module is preferably five times as large, in particular at least ten times as large, as the surface of the light exit edge. The light exit edge is, in particular, a very narrow surface strip. It is, in particular, rectangular in shape. Two opposite boundary edges of the surface of the light exit edge are many times larger, in particular at least 10 times, in particular at least 20 times, than the two other, shorter, opposite boundary edges.The shorter boundary edges can be provided to be between 0.3 cm and 3 cm long.

[0010] Furthermore, such a concept makes it possible for a user to see a narrow band of light when the light source module is activated. This allows for a highly customized optical illumination scenario of the receiving space toward the loading opening. In particular, one embodiment also enables very bright illumination, since this narrow light exit edge also enables a stronger light emission.

[0011] According to the invention, the cover is a diffuser plate. It can also be referred to as a scattering plate. Light from the at least one light source of the light source module is therefore scattered accordingly by the diffuser plate. This enables uniform light emission with a homogeneous light pattern.

[0012] Furthermore, one embodiment also allows light from the light source to be emitted via the front surface in addition to the light exit edge. In this regard, light can then be emitted over a larger area, particularly to the rear into the receiving space. The front surface extends in a plane oriented at an angle greater than 0°, in particular greater than 30° and less than 120°, to the plane in which the light exit edge extends.

[0013] It can be provided that the plane in which the light-emitting edge extends is spanned by the depth and height directions of the household refrigeration appliance. The plane of the light-emitting edge can also be arranged at an angle relative to a vertical plane spanned by the depth and height directions of the household refrigeration appliance. In particular, it can be arranged at an angle forward toward the loading opening. In this context, an acute interior angle can be formed between this vertical plane and the plane of the light-emitting edge. This can further improve the light emission from the light-emitting edge forward toward the loading opening.

[0014] In one embodiment, the edge is oriented obliquely and faces a front loading opening of the inner container, with the edge forming the front end of the cover. The edge can be arranged in its plane of extension at an angle to the wall region, which, particularly when viewed in the depth direction, adjoins the edge toward the front. 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 toward the front.

[0015] In one embodiment, it is also possible for the cover to have a light-guiding structure through which the light from the at least one light source of the light source module can be directed in a targeted manner to the light exit edge. In particular, this structure is arranged in the cover, so that the light guidance defined in this regard takes place within the cover toward the light exit edge. This allows the proportion of light exiting the light exit edge to be individually increased. This enables particularly powerful light emission from the light exit edge.

[0016] In one embodiment, the cover is oriented at an angle to the vertical plane of the household refrigeration appliance. The vertical plane is spanned by the depth direction and the height direction of the household refrigeration appliance. In particular, a front end of the cover in the depth direction of the household refrigeration appliance is arranged further inwards in the width direction of the household refrigeration appliance than a rear end of the cover. This means that the front end of the cover protrudes further into the receiving space than the rear end. By positioning the cover at an angle of this type, the above-mentioned lighting concept can be improved in a particularly advantageous manner. This orientation already fundamentally supports the desired light emission, in particular from the light exit edge at least partially towards the front. In addition, the preferably possible light emission via the front surface towards the rear is also correspondingly supported.Since the front surface is also exposed towards the recording room, this also allows for targeted light emission into the rear area of the recording room.

[0017] In one embodiment, the light source module has a housing on which the cover is arranged. The cover can be a separate component from the housing. In one embodiment, it is also possible for the cover and the housing to be manufactured as a single piece.

[0018] In one embodiment, the cover is made of plastic. However, it can also be made of real glass. In one embodiment, the cover is formed as a single piece. It is, in particular, transparent. This means that it is permeable to light in the spectral range visible to humans.

[0019] In one embodiment, the housing has an inner housing wall, viewed in the width direction of the household refrigeration appliance. A front side of the inner housing wall is arranged to extend further inward, viewed in the width direction, than a front end of the cover. This inner housing wall is thus arranged closer to the receiving space, or further into the receiving space, viewed in the width direction, than an outer housing wall of the housing, viewed in the width direction. By arranging this front side, which faces away from the interior of the housing of the light source module, further inward in the receiving space than the front end, a certain degree of glare protection for an observer is also achieved.The resulting widthwise overhang of the front panel relative to the front end of the cover, formed by the light-emitting edge, also provides a certain degree of impact protection, so that the light-emitting edge is also protected in this regard. In the width direction, the overhang of the front panel relative to the light-emitting edge can be between 1 mm and 5 mm.

[0020] In one embodiment, the housing of the light source module has an outer housing wall, viewed in the width direction of the household refrigeration appliance. In one embodiment, this outer housing wall has a receptacle in which a rear end of the cover is arranged. In one embodiment, the receptacle is a thinning of the wall of this outer housing wall. As a result, the rear end of the cover, when arranged on the housing in this respect, overlaps with this outer housing wall. This enables correspondingly advantageous positioning and a mechanically secure fit of the cover on the housing at this rear end of the cover. Furthermore, this configuration means that the rear end of the cover is not exposed, but is covered by the outer housing wall. In particular, a complete cover is formed here.

[0021] In one exemplary embodiment, the cover has at least one snap element on an inner side facing the housing, which is snapped onto at least one counter-snap element on the separate housing of the light source module. Such a mechanical coupling between these two separate components is mechanically highly functional, easy to produce, and user-friendly for assembly and disassembly. In this context, in one exemplary embodiment, the cover can be assembled by sliding it sideways. To enable disassembly even when the light source module is installed, one exemplary embodiment provides for a placeholder to be arranged at an upper end in the vertical direction. This allows the cover to be very easily removed from the housing by slightly lifting it in the upper area and sliding it sideways upwards.

[0022] In one embodiment, the cover rests with its inner side facing the housing against a free edge of the inner housing wall. This free edge is a peripheral edge of the inner housing wall. This also ensures mechanically secure and stable positioning. In one embodiment, the cover overlaps both the free peripheral edge of the inner housing wall and the free peripheral edge of the outer housing wall.

[0023] In one exemplary embodiment, the light-emitting edge of the cover is arranged directly adjacent to a front side of an inner housing wall of the housing, viewed in the depth direction of the household refrigeration appliance. In this regard, the front side is the side facing away from the interior of the housing and facing the receiving space. As a result, viewed in the depth direction of the household refrigeration appliance, an arrangement in series is formed between this front side of the inner housing wall and the light-emitting edge. The light-emitting edge is formed with a dimension in this depth direction that is much smaller than the extension of the front side in this depth direction. In particular, the front side is at least five times, in particular at least eight times, as long as the light-emitting edge.

[0024] In one embodiment, the cover is L-shaped when viewed in cross-section. As already explained above, in one embodiment the cover is an elongated plate or an elongated rail. In this regard, it has a longitudinal axis along its longer dimension. The cross-section is viewed perpendicular to this longitudinal axis. A first L-leg of this L-shape covers an opening in the housing. A second L-leg of the L-shape is oriented protruding therefrom. It is oriented away from the housing. An exposed end of the second L-leg facing away from the first L-leg forms the edge or the light exit edge of the cover. With this embodiment, the light exit edge is offset further outwards towards the adjacent wall of the inner container when viewed in the width direction and further rearwards from the housing of the light source module when viewed in the depth direction.This also enables an individual light emission concept via this light exit edge.

[0025] In one embodiment, the housing is an elongated, hollow rail. It has a U-shaped cross-section. This cross-section is also perpendicular to a longitudinal axis of this elongated rail.

[0026] At least one light source, in particular a light-emitting diode, is arranged inside the housing. Multiple light-emitting diodes can also be arranged in this regard. Corresponding electronics of the light source module can also be arranged in the housing.

[0027] In one embodiment, the inner 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. This ensures that the light source module is recessed, at least in some areas, and does not protrude undesirably above or too far into the receiving space. This embodiment allows the light source module to be positioned more compactly. It is also more mechanically stable to mount and is better protected against impacts or similar effects.

[0028] In one embodiment, a housing wall facing the receiving space is arranged flush with a wall region of the wall adjacent to the receiving recess. As a result, the light source module is recessed into the receiving recess, as viewed in the width direction, so that there is no overhang. The aforementioned advantages are thus achieved to a significant degree.

[0029] It is also possible for the cover to be colored. This makes it easier to see the light exit edge even when the light source module is switched off. In particular, this type of material coloring can create an individual contrast to neighboring components, so that the light exit edge is visually separated from the other neighboring components even when the light source module is switched off. It is also possible for the cover, if it is designed as a separate component from the housing of the light source module, to be connected to the housing not only by a non-destructively detachable connection, such as at least a snap connection. Rather, a permanent connection can also be provided here. For example, gluing or welding can be provided here.

[0030] It is also possible for the housing and cover to be designed as a single-piece component, for example, as a two-component plastic part. It is also possible for the light exit edge to be formed only over a portion of the entire light source module. In particular, it is formed over the entire length of the light source module.

[0031] When the household refrigeration appliance is assembled, the outside of the inner container may be covered with a thermally insulating material, in particular rigid polyurethane foam.

[0032] The inner container can be made of plastic, in particular polystyrene, and can be produced by deep drawing or injection molding.

[0033] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction", etc., indicate the positions and orientations given when the device is used and arranged as intended.

[0034] Embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: Fig. 1 is a perspective view of an embodiment of a household refrigeration appliance according to the invention; Fig. 2 is a perspective partial section of the view in Fig. 1 ; Fig. 3 a perspective sectional view through the embodiment in Fig. 2 ; Fig. 4 the representation of the arrangement in Fig. 3in the sectional plane; Fig. 5 shows a perspective sectional view of a further embodiment of a household refrigeration appliance according to the invention; Fig. 6 shows a perspective sectional view of a further embodiment of a household refrigeration appliance according to the invention; and Fig. 7 shows a perspective view of a further embodiment of a household refrigeration appliance according to the invention.

[0035] In the figures, identical or functionally identical elements are provided with the same reference numerals.

[0036] In Fig. 1 A perspective view of an embodiment of a household refrigeration appliance 1 is shown. The household refrigeration appliance 1 is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator, a freezer, or a refrigerator-freezer combination appliance.

[0037] The household refrigeration appliance 1 can be a free-standing household refrigeration appliance or a built-in appliance.

[0038] The household refrigeration appliance 1 has an outer casing 2. In addition, the household refrigeration appliance 1 has an inner container 3. This is separate from the outer casing 2. The inner container 3 is accommodated in the outer casing 2. Thermally insulating material 5 is introduced into a space 4 between the outer casing 2 and the inner container 3. The 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 household refrigeration appliance 1. The receiving space 11 is intended for receiving food. It can be a refrigerator compartment or a freezer compartment. The household refrigeration appliance 1 also has a door 12. This is movably arranged on the body, which comprises the outer casing 2 and the inner container 3. This allows a front loading opening 13 of the inner container 3 to be closed.

[0039] The household refrigeration appliance 1 further comprises at least one light source module 14. This 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 merely as an example. In addition to or instead of this, a light source module can also be arranged, for example, on an inner side of the wall 7 and / or on an inner side of the wall 8 and / or on an inner side of the wall 6.

[0040] As in Fig. 1 As already indicated, the wall 9 is provided on the inner side 9a with a receiving recess 15. This blind-hole-like recess is intended to accommodate the light source module 14. The light source module 14 is therefore arranged at least partially recessed in the wall 9.

[0041] In Fig. 2 is an enlarged view of section I in Fig. 1shown. It can be seen that the light source module 14 is designed here as an elongated rail. It is oriented here with a longitudinal axis A in the vertical direction (y-direction) of the household refrigeration appliance 1. In the width direction (x-direction) of the household refrigeration appliance 1, the receiving recess 15 is formed to the side, so that the light source module 14, viewed in the width direction, is recessed into this receiving recess 15.

[0042] The light source module 14 has a housing 16. In Fig. 2 In this regard, an inner housing wall 17 can be seen. In the exemplary embodiment, this is exposed towards the receiving space 11. In particular, this inner housing wall 17 has a front side 17a. This is the visible side facing the receiving space 11. The inner housing wall 17 is designed here as a plate-like strip. In addition, the housing 16, as shown in the perspective sectional view in Fig. 3As can be seen, the housing 16 has an outer housing wall 18. The outer housing wall 18 is arranged further away from the receiving space 11 than the inner housing wall 17, viewed in this width direction. Furthermore, the housing 16 has a connecting wall 19. This is provided for connecting the inner housing wall 17 and the outer housing wall 18.

[0043] In the exemplary embodiment, the housing 16 is U-shaped in cross section viewed perpendicular to the longitudinal axis A.

[0044] At least one light source 21 is arranged in the interior 20 of the housing 16. The light source 21 can comprise a light-emitting diode. In addition, electronics of the light source module 14 are also arranged in the interior 20. As further shown in Fig. 3As can be seen, the light source module 16 has a cover 22. The cover 22 is transparent at least in some areas. The cover 22 is designed here as an elongated plate strip. This plate in question has a front surface 23. The front surface 23 faces away from the interior 20. The front surface 23 faces the receiving space 11. The front surface 23 is exposed towards the receiving space 13. The front surface 23 is a large-area front side with respect to the strip-shaped plate. In contrast, this cover 22 also has a rear surface 24. This lies opposite the front surface 23. The rear surface 24 faces the interior 20. As provided for in a plate-like design of a component, the cover 22 also has a peripheral edge 25. This peripheral edge 25 is a narrow side of the cover 22. The peripheral edge 25 is designed here as a light exit edge 26, as intended and functionally required.This means that defined and desired light from the light source 21 emerges as intended from this edge 25, which forms the light exit edge 26. As can be seen, this light exit edge 26 is a narrow strip area. This strip area is smaller, in particular much smaller, than the large area of the front surface 23 and / or the large area of the rear surface 24. The light exit edge 26 extends with its area facing the receiving space 11. It is exposed, in particular completely exposed, towards the receiving space 11. It can be spanned in a plane formed by the height direction and the depth direction (z-direction) of the household refrigeration appliance 1. However, the plane in which the light exit edge 26 extends flat can also be arranged inclined to a plane spanned by the height direction and the depth direction of the household refrigeration appliance 1.

[0045] In particular, in such an embodiment, this plane of the light exit edge 26 can be arranged at an acute angle to the vertical plane and, in this context, oriented at this acute angle toward the loading opening 13. Through these light exit edges 26, light is also emitted, as intended, at least partially forward into the front area of the receiving space 11, in particular also toward the loading opening 13. This light exit edge 26 is arranged completely exposed toward the receiving space 11.

[0046] The light exit edge 26 is here a vertical surface strip.

[0047] The cover 22 further has another opposite edge 27. This faces the wall 9. It is not designed or arranged for light emission. In the exemplary embodiment, the edge 25, and thus the light exit edge 26, is oriented obliquely. Viewed in the depth direction, the edge 25 forms the front end 28 of the cover 22. The cover 22 is designed, in particular, as a diffuser plate or light scattering plate.

[0048] As in Fig. 3As can also be seen, the cover 22 is oriented with its plate-like element at an angle to the vertical plane. In particular, the front end 28 of the cover 22, viewed in the depth direction of the household refrigeration appliance 1, is offset further inward toward the receiving space 11 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.

[0049] In one exemplary embodiment, it can be provided that, viewed in the width direction, the front side 17a of the inner housing wall 17 is arranged further into the receiving space 11 than the front end 28 of the cover 22. In particular, a corresponding offset in the width direction is also formed between the front side 17a and the light exit edge 26. However, it is also possible that, in one exemplary embodiment, the light exit edge 26 is arranged in the width direction at the same width position as the front side 17a. In particular, this is provided when the planes of the front side 17a and those of the light exit edge 26 extend in a common plane or in planes parallel to one another.

[0050] In contrast, in another embodiment, as already mentioned above, the plane in which the light exit edge 26 extends can also be arranged at an angle to the vertical plane. As a result, this plane is also oriented at an angle to the front side 17a. In particular, this light exit edge 26 is then oriented at an angle toward the loading opening 13.

[0051] In one embodiment, the outer housing wall 18 is provided with a receptacle 30. The rear or outer end 29 of the cover 22 extends into this receptacle 30. In the exemplary embodiment, this receptacle 30 is formed by a reduced-thickness end region of the outer housing wall 18. As can be seen, the outer peripheral edge 27 is completely covered by this receptacle 30.

[0052] In addition, Fig. 3It can also be seen that the cover 22, viewed in the width direction, projects beyond a free end 31 of the inner housing wall 17 and thus covers this free end 31 at least in part.

[0053] Furthermore, it can also be seen that the cover 22 has at least one snap element 32. This is snapped to at least one counter-snap element arranged on the housing 16. Preferably, several snap elements and counter-snap elements are provided. Fig. 3 It can also be seen that the cover 22 rests with the inner side or rear surface 24 against the free end or the free edge 31 of the inner housing wall 17. In addition, Fig. 3 It can also be seen that, viewed in the depth direction of the household refrigeration appliance 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.

[0054] In Fig. 4is the component arrangement in Fig. 3 shown in the section plane. In Fig. 4 In this regard, a section plane or a horizontal section plane is shown, which is different from Fig. 3 is. In Fig. 4 In this context, it can also be seen that the housing 16 has a coupling part 33. This extends through a recess 34 in the wall 9, in particular in the receiving recess 15. This coupling part 33 thus extends into the intermediate space 4. In one embodiment, a separate backing part or mounting part 35 is arranged in the intermediate space 4. This allows the light source module 14 to be attached to this mounting part 35.

[0055] In Fig. 51 shows a perspective sectional view of a further exemplary embodiment of a household refrigeration appliance 1. A section is shown here, showing the wall 7 of the inner container 3. In this exemplary embodiment, the cover 22 is not completely flat with the front panel, but rather the front panel is angled in this respect. As a result, the front surface 23 is uneven, in particular angled. In this exemplary embodiment, it is again provided that the surface of the light exit edge 26 extends in a vertical plane spanned by the depth direction and the height direction. In this exemplary embodiment, a flush arrangement with the front side 17a is realized, so that in particular the plane of the front side 17a is the same as the plane of the light exit edge 26.

[0056] In Fig. 6A further embodiment is shown, which corresponds to the illustration in Fig. 5 The difference to the embodiment in Fig. 5 It can be seen here that the light exit edge 26 is arranged further offset into the receiving space 11 due to an overhang in the width direction compared to the front side 17a. This forms a further light exit edge 36 which projects beyond the front side 17a in the width direction. It is therefore completely exposed towards the front when viewed in the depth direction. The plane of this further light exit edge 36 can be spanned by the width direction and the height direction. It can also be provided that the plane in which this further light exit edge 36 extends or spans in terms of area is arranged inclined to this vertical plane.

[0057] In Fig. 7 is in a perspective view according to Fig. 5and Fig. 6a further exemplary embodiment of a household refrigeration appliance 1 is shown. In this exemplary embodiment, a different design of the cover 22 is provided. The light exit edge 26 is not arranged directly adjacent to the front side 17a of the inner housing wall 17 when viewed in the depth direction. Rather, the cover 22 is L-shaped when viewed in cross-section. A first L-leg 37 is arranged such that it rests against the housing 16 or closes or covers an opening in the housing 16. In the exemplary embodiment, this L-leg 37 does not have a thin light exit edge that would be exposed. This cover 22 has a second L-leg 38. This protrudes at an angle from the first L-leg 37, in particular protrudes away from the housing 16. An exposed end 39 of this second L-leg 38 has the peripheral edge 25 and thus the light exit edge 26. This is inclined.

[0058] It is also possible that in one embodiment a combination of the cover 22 as shown in Fig. 5 and Fig. 6 shown, with the cover according to Fig. 7 Such a cover 22 then also has a light exit edge 26 or 36 exposed to the side or to the front, which, viewed in the depth direction, is formed directly to the rear adjoining the front side 17a.

[0059] As can also be seen in the exemplary embodiments, as already mentioned above, a flush arrangement is preferably provided between the front side 17a and the wall area of the wall 7 or wall 9 adjoining it in the depth direction. These wall areas 40 ( Fig. 3 ) and 41 ( Fig. 5 to 7 ) are shown accordingly. List of reference symbols
