Definitions

  • One aspect of the invention relates to a household refrigeration appliance with a housing.
  • a first, upper receiving space for foodstuffs, viewed in the vertical direction, is formed in the housing.
  • a second, lower receiving space for foodstuffs, separate from the first receiving space, is formed in the housing.
  • the two receiving spaces are separated from one another at the front by a cross-member of the household refrigeration appliance, viewed in the depth direction of the household refrigeration appliance.
  • the household refrigeration appliance also has a light module, which is arranged on a front side of the cross-member.
  • the light module has a module housing.
  • the module housing has a front housing part, viewed in the depth direction of the household refrigeration appliance. This front housing part has a lower wall, which is a light exit window.
  • a lighting unit is arranged on the front side of a cross-connection.
  • the cross-connection separates a cooling compartment from a freezing compartment.
  • Light can be emitted downwards through this lighting unit, which is arranged locally on the front.
  • This lighting unit has a one-piece housing.
  • a transparent cover is arranged on this housing. This cover is snapped directly onto the cross connection with a projection in the form of a rib.
  • the housing is snapped directly onto a fastening element.
  • the fastening element is separate from the housing and separate from the cover.
  • the fastening element is arranged directly on the cross connection.
  • fastening tabs of the metal fastening element must be passed through fastening openings in the cross connection and then bent laterally over the edges of the fastening openings and clamped to them.
  • the cover which is convex in cross section in the front area, is covered on the inside by a non-transparent apron. This prevents light from escaping to the front.
  • the lighting unit known from the state of the art is made up of a variety of components that have to be individually connected, which is very complex.
  • the assembly work of the housing on the separate mounting bracket and in particular the fastening of this mounting bracket to the cross connection are very assembly-intensive. This also results in position tolerances.
  • the lighting unit is therefore very difficult to position precisely on the cross connection.
  • the lighting functionality of this lighting unit is limited. Due to the arrangement of the light source in the housing and the shape of the cover, the light can only be emitted downwards with a vertical main beam direction. This is particularly disadvantageous as it only offers lighting in a very narrow area below the lighting unit. In particular, this creates a bright spot of light directly below the lighting unit and on the adjacent front of the cross connection. This prevents a homogeneous light image. In addition, water and moisture can get into the housing through the mounting bracket.
  • JP 2019 019987 A discloses a storage container with a lighting device on the inner ceiling wall of the storage container.
  • JP-H11 132650 A discloses a storage space with a partition plate between a refrigerator compartment and a vegetable compartment, wherein the partition plate has a lamp for illuminating the vegetable compartment.
  • EP 2 317 264 A1 discloses a refrigeration appliance with a lamp which illuminates the refrigerated goods when the door is open and a light surface attached to the outside of the housing when the door is closed.
  • the invention relates to a household refrigeration appliance with a housing.
  • the two receiving spaces are separated from one another at the front by a cross-member of the household refrigeration appliance, viewed in the depth direction of the household refrigeration appliance.
  • the household refrigeration appliance also has a light module, which is arranged on a front side of the cross-member.
  • the light module has a module housing.
  • the module housing has a front housing part, viewed in the depth direction of the household refrigeration appliance. This front housing part has a lower wall, which is a light exit window.
  • a lower wall of the front housing part viewed in the vertical direction, has a partial area or a partial section. This partial area is oriented diagonally upwards relative to a horizontal. This means that, viewed in the depth direction, starting from one end or one side of this partial area that is closer to the cross member, this partial area of the lower wall is oriented so as to rise forwards and upwards. In particular, a straight and continuous diagonal orientation is formed here.
  • a light channel is formed inside the module housing. Through this light channel, a light exit is defined and intended and thus in particular a main radiation direction of the light from the module housing through the lower wall is oriented diagonally to a vertical. The light module is therefore provided with a very specific directed light exit downwards and diagonally forwards.
  • the angle between the vertical and the main radiation direction is between 20° and 70°, in particular between 25° and 60°.
  • this design of the very compact light module means that a larger area or zone in front of the recording room can be evenly illuminated.
  • the light channel has a reflection wall.
  • This reflection wall is oriented at an angle to the vertical.
  • the light from a light source of the light module is reflected in the module housing by this reflection wall in a direction away from the cross-member.
  • the light is reflected by this reflection wall in the desired light exit orientation.
  • the lower wall has a further partial area for light emission.
  • This further partial area ends at an end of the inclined partial area facing away from the cross-beam in the depth direction.
  • the partial area is inclined more upwards relative to the horizontal than the slanted, first partial area. This means that in this embodiment, it is possible for light to be emitted more towards the front.
  • this further partial area can create a band of light which is visible from the front and shines forwards. This can also be used to display a line of light, for example.
  • this is intended so that, viewed in the vertical direction, this line of light is positioned in a gap between the upper door, which closes the upper receiving space, and the lower door, which closes the lower receiving space. Even when the doors are closed, the gap between the doors can then be illuminated by this line of light. This makes it possible, for example, to visually signal the lower edge and the upper edge of these two doors even when there is a greater distance and/or in darker visibility conditions.
  • the further partial area of this lower wall has a vertically oriented outer side.
  • this further partial area can also have a vertically oriented inner side. In this respect, a very individual light emission can then take place towards the front out of the module housing.
  • the outside of the oblique, first partial region of the lower wall is flat. In one embodiment, the inside of this oblique, first partial region of the lower wall can be oriented parallel to the outside.
  • this further partial area is also present, there is a kink or an angular transition between the outer side of the slanted, first partial area and the directly adjacent outer side of the further, second partial area.
  • the front housing part with the upper wall and the lower wall is made of plastic.
  • this housing part is a one-piece component. It can in particular be a 2K component.
  • the module housing has a rear housing part when viewed in the depth direction of the household refrigeration appliance.
  • This rear housing part has a rear wall and several separate snap elements.
  • the snap elements are formed in one piece with the rear housing part.
  • the snap elements are snapped into snap element receptacles that are formed on the cross member.
  • the rear housing part is arranged with a rear surface of the rear wall, viewed in the depth direction, directly adjacent to the front of the cross member. This type of design enables the light module to be attached directly to the cross member in a particularly simple and yet positionally stable manner. The assembly effort is reduced in this regard. Snap connections can provide a very quick and effective assembly concept.
  • these several snap elements and several snap element receptacles also enable the light module to be attached in a permanently fixed position.
  • This design means that the module housing itself lies directly on the front of the cross member.
  • the snap elements formed in one piece with it reach backwards through snap element receptacles and are snapped into them. This enables a simple fastening concept.
  • separate mounting brackets for the housing are no longer required, as is necessary in the state of the art.
  • a first, eccentric snap element and a separate second, eccentric snap element are formed on the rear wall.
  • these snap elements are arranged offset to the left and right from a center point or a center of the rear wall when viewed in the width direction of the household refrigeration appliance and thus also when viewed in the width direction of this rear wall.
  • these two snap elements are arranged symmetrically to a center of the rear housing part when viewed in the width direction of this rear wall and thus of the rear housing part.
  • the snap element holder in the crossbeam is designed symmetrically to a center point of this crossbeam viewed in the width direction. This then also makes it possible for this crossbeam to be mounted with symmetry. This means that during production it is no longer necessary to pay close attention to the only installation position in which the crossbeam must be arranged. Rather, a first position and a second position of the crossbeam rotated by 180° (again, around an axis viewed in the depth direction) are possible. In particular, this also has the advantage that after mounting a backing part behind the crossbeam, in particular together with an electrical plug, on this centerbeam or crossbeam, the symmetry of this crossbeam is maintained. In particular, a production employee does not have to pay attention to which side of the crossbeam the inner container that delimits the first receiving space and which side the inner container that delimits the second receiving space must be arranged.
  • a central snap element is formed on the rear wall, which is arranged centrally in the width direction of the rear housing part. This further improves a mechanically stable fastening of the rear housing part directly to the cross member in a particularly advantageous manner.
  • this arrangement also continues to provide the above-mentioned advantage of the reversible symmetry.
  • a central snap element receptacle is formed in the cross member. The central snap element can snap into this. This also means that the cross member is still designed to be reversible symmetrical, so that the above-mentioned advantages are retained.
  • the central snap element has two spaced apart snap element parts. These snap element parts are each individually snapped into a, in particular single, central snap element receptacle of the cross member. This design of the central snap element enables a enables particularly advantageous mechanical coupling. In addition, these snap element parts can be used more effectively for other functions.
  • these snap element parts have snap lugs on the sides facing away from each other.
  • the snap element parts are snapped into the snap element holder in the cross member using these snap lugs.
  • These snap element lugs which are oriented outwards in the width direction, ensure that the space between the snap element parts is maximized in this width direction. This means that this space can be used more effectively for the introduction of other components. This also enables a particularly compact structure, particularly in the depth direction of the light module.
  • the snap element parts are designed with engagement elements on the sides facing each other. These engagement elements are designed to engage in engagement areas of the circuit board of the light module. This is another very advantageous embodiment. This is because it allows the direct mechanical coupling between this specific central snap element and the circuit board to be achieved. The direct mechanical holding coupling in this regard also enables a particularly advantageous position-fixed arrangement of the circuit board.
  • the snap element parts are therefore multifunctional. On the one hand, they are intended to snap onto the cross member itself, and on the other hand, they are intended to directly snap the circuit board into place.
  • the board is thereby held securely in position in at least two spatial directions, in particular the depth direction and the width direction. It extends in particular into the space between the snap element parts.
  • the board is arranged overlapping with this central snap element when viewed in the depth direction.
  • the snap element parts extend in the depth direction at least over the entire depth of the partial area of the board that extends into the space between the snap element parts.
  • the snap element parts have receiving and guide slots for a portion of the circuit board on the inner sides facing each other.
  • a receiving area for a portion of the circuit board of the light module is formed between the snap element parts. This receiving area is thus intended so that this portion of the circuit board can be positioned therein.
  • a partial area of the board is held between the snap element parts.
  • this partial area is snapped onto it by the engagement of the engagement elements in these engagement areas.
  • the engagement elements extend in the width direction, as do the engagement areas. This creates an interlock in the width direction.
  • the snap elements are arranged on the rear wall in a spring-loaded manner, particularly in the width direction. This allows the snap-in process to be carried out particularly smoothly.
  • the cross-member has a horizontal slot that is designed to allow the circuit board to extend through. A portion of the circuit board extends through this slot in the cross-member.
  • the slot is designed centrally in the middle of the cross-member. This makes it possible for the circuit board to extend on both sides of the cross-member when installed. This also allows the light module to have a compact structure and the circuit board to be positioned more securely.
  • the part of the circuit board that extends through this slot which in particular also forms the entrance of the central snap element receptacle, of the cross member to the rear into the housing of the household refrigeration appliance is provided with electrical contacts that are designed to electrically contact a plug that is arranged in the housing.
  • electrical contacts are provided in this regard.
  • the part of the circuit board that extends through the slot in the cross member to the rear into the housing of the household refrigeration appliance is narrower than another part of the circuit board that is arranged in front of the cross member.
  • the circuit board has a T-shape.
  • a portion of the circuit board is a T-trunk. This portion is in particular the one that extends backwards through a slot in the rear wall of the rear housing part.
  • this T-trunk also extends through the recess or the snap element holder in the cross member.
  • Another portion of this T-shape is a T-roof. This additional portion is arranged on the front side of the rear wall of the rear housing part. It therefore does not extend through the slot in the rear wall of the rear housing part. Viewed in the width direction, the slot in the rear wall is narrower than the T-roof of the circuit board.
  • This shape and the arrangement of the circuit board relative to this rear wall also allow it to be positioned more stably. In particular, a particularly compact structure is also possible.
  • the module housing has a front housing part, viewed in the depth direction of the household refrigeration appliance. This therefore extends further forward than the rear housing part.
  • the front housing part has a lower wall when viewed in the vertical direction of the household refrigeration appliance.
  • This lower wall forms a light exit window of the light module.
  • the lower wall is oriented obliquely upwards relative to a horizontal. This means that it is oriented obliquely upwards and forwards starting from the end or the side that faces the crossbar and is closer to the crossbar in this respect.
  • this oblique orientation means that the light cannot be emitted vertically downwards with a main radiation direction, but rather obliquely downwards and forwards away from the receiving space. This enables particularly homogeneous illumination of this zone. This way, unwanted light spots that occur directly below the light module, especially on the front of the crossbar, can be avoided.
  • the household refrigeration appliance has a food receptacle that is arranged so that it can be moved in the second receptacle space.
  • This then makes it possible for the light module to provide uniform illumination from above when the food receptacle is pulled out in a position that is also pulled out in this respect.
  • This also makes it possible to illuminate the interior of the food receptacle particularly extensively and homogeneously in the maximum pull-out position of the container.
  • the food receptacle is in particular a bowl. This can also be pulled out and pushed in linearly in the depth direction from the second receptacle space. It is precisely this very advantageous design of the light module with this slanted wall and the corresponding light output that enables the entire interior of this shell to be illuminated as extensively and evenly as possible, even if this shell is relatively large and is pulled relatively far forward.
  • the front housing part has an upper wall, viewed in the vertical direction.
  • This upper wall is opaque. This ensures that no unwanted light escapes upwards. This enables a very directed light output via this specified lower wall. In particular, this also prevents blinding of an observer who is looking at the light module from above or diagonally from above. In particular, if a shell as described above is present and this is pulled out and the observer looks into the interior of the shell from above, the shell is evenly and comprehensively illuminated and the observer is not blinded by the light module.
  • this upper wall is oriented diagonally downwards with respect to a horizontal. This means that, viewed in the depth direction, it is oriented diagonally downwards and forwards, starting from the end or side that is closer to the cross member.
  • This geometry results in a particularly advantageous, two-sided tapering of the front housing part towards the front. This reduces the space required for the light module upwards and downwards.
  • an advantageous geometry is achieved in this context. Due to this orientation of the front housing part, which is diagonal both upwards and downwards, the geometry of this front housing part is tapered in cross section. This means that only minimal space is required in the vertical direction between the doors of this front housing part.
  • an electronic display can also be formed on this upper wall. This allows electronic information to be displayed visually.
  • the front housing part is truncated pyramid-shaped.
  • top, bottom, front, “back”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction” etc. indicate the positions and orientations that occur when the device is used and arranged as intended.

  • this lower wall 48 is oriented with a partial area 50 obliquely upwards to the horizontal H. This means that starting from one side or one end of this lower wall 48, which is closer to the cross-member 6, an orientation that is obliquely upwards and forwards is provided.
  • an outer side 51 of this obliquely upwardly oriented partial area 50 is straight in the sectional view. This means that this surface of the partial area 50 is flat in one embodiment.
  • An inner side 52 of this partial area 50 can also be flat.
  • a specific light channel 53 is formed inside the module housing 15. This causes the light L of the light source 40 to exit the module housing 15 via the lower wall 48. According to the invention, this light channel 53 achieves a defined and directed light exit from the module housing 15 via this lower wall 48. According to the invention, this light channel 53 has a reflection wall 54 for this purpose. This is oriented at an angle to a vertical V. This is such that the reflected light exits this module housing 15 at an angle to the front and bottom relative to this vertical V. This homogeneously illuminates a zone 55 that is located in front of the lower receiving space 4 in the depth direction and also further forward. In particular, in Fig.6 In this regard, a main radiation direction LH of the light L is shown.
  • a kink 59 is formed between the outer side 57 and the outer side 51.
  • Fig.6 the advantageous geometry of the module housing 15 can also be seen.
  • a maximum distance to the doors 7 and 8 is achieved by these inclined upper and lower walls 46 and 48.
  • the freedom of movement of the doors 7 and 8 is not restricted, in particular in the depth direction towards the cross member 6.
  • a lowering of the upper door 7 in the height direction can occur, for example, after loading with stored goods in door racks, which occurs over the service life of the household refrigeration appliance 1.
  • Such a movement of the door is then not harmful to the light module 10, so that no undesirable contact occurs in this regard.
  • Fig.5 is a horizontal section through the arrangement according to Fig.2 shown along the section line VV.
  • the final assembled state of the light module 10 on the crossbar 6 can be seen.
  • the rear wall 18 with the rear surface 19a lies flat against the front side 11 of the crossbar 6.
  • the eccentric snap elements 20 and 21 are snapped into the eccentric snap element receptacles 12 and 13.
  • the snap element parts 23 and 24 are also snapped into the snap element receptacle 24.
  • the engaged state between the engagement elements 30 and 31 of the engagement regions 32 and 33 is shown.
  • the partial area 35 has further slots 60 and 61.
  • Webs 63 and 64 engage in these rear-open slots 60 and 61, which are formed on a rear edge 62 of the partial area 35.
  • These webs 63 and 64 are part of a coupling component with which the light module 10 is coupled in the assembled final state.
  • These webs 63 and 64 can be integrated into the component 6a.
  • the component 6a can also accommodate the electrical plug.
  • the snap elements 20 and 21 are hollow. This reduces their weight and allows for a certain degree of deformability. For the sake of clarity, Fig.5 No hatching of the cutting planes of the individual components is shown.
  • the module housing 15 is tapered towards the front when viewed in the depth direction.
  • a vertical sectional view of the household refrigeration appliance 1 is shown in the area of the cross member 6.
  • the doors 7 and 8 are shown here in the closed state.
  • a first illumination area 65 is shown here, which is generated when light L is only emitted via the partial area 50 of the lower wall 48.
  • a light area 66 is shown, which is emitted when, in addition to the light exiting via the slanted partial area 50, light L is emitted outwards via the further partial area 56.
  • FIG.8 A schematic representation of a vertical sectional view of the household refrigeration appliance 1 is shown in part.
  • the household refrigeration appliance 1 here has a food receptacle 67. This is arranged in the lower receiving space 4 so that it can be moved in the depth direction.
  • This food receptacle 67 can be a bowl, for example.
  • Fig.8 it is shown in an extended state. In this respect, it is still partially arranged within the receiving space 4, but can be viewed and loaded from above or stored goods can be removed from it.
  • This maximum extension position shown here in particular is also such that this bowl is located in the area of zone 55.
  • the light L is evenly radiated into the interior of this food container 67, so that this interior is homogeneously and comprehensively illuminated.
  • this design creates a preferred, material-locking and stable connection between the two housing halves.
  • this design also provides improved stability against mechanical influences.
  • the module housing 15 can be designed as a 2K component. This makes it possible to advantageously produce a possible beam angle of the light L in this obliquely forward and downward oriented direction.
  • This further portion 56 of the lower wall 48 can also be referred to as a diffuser.
