Description

Household refrigeration appliance with a receiving element for a shelf, which has an OLED light source

The invention relates to a domestic refrigerator with an interior, which is designed to hold food, and is bounded by walls of an inner container, wherein on vertical walls holding devices are formed for at least one interior element.

It is known and customary for household refrigerators, such as refrigerators, freezers or refrigerated combined freezers, to have one or more shelves in the interior space on which foodstuffs can be arranged. The lateral support of these shelves is known in various designs. These are usually integrally formed on the lateral vertical walls of the inner container formed by, for example, a deep drawing fixtures on which rests the shelf. These molded cams thereby require a relatively rugged inside of the vertical wall, whereby the cleanability of this inside is difficult. In addition, cavities are then formed on the outer sides of these vertical walls, which make it difficult to install vacuum insulation elements in a space between the inner container and an outer container or an outer housing. This is because as a result of the unevenness of this outside, the largest possible flat and flush installation of a vacuum insulation element is difficult or impossible.

The holding devices with receptacles for shelves are functionally limited. It is an object of the invention to provide a household refrigerating appliance, in which a receiving element for an interior element is formed multifunctional.

This object is achieved by a household refrigerator according to the features of claim 1.

A domestic refrigerator according to the invention comprises an interior which is designed to receive food and is delimited by walls of an inner container. On vertical walls of the inner container holding devices for at least one interior element, in particular a shelf, are formed. An essential idea of the invention is to be seen in that the holding device has a rail-like receiving element arranged on the inside for a shelf which has at least one guide area for receiving the shelf, wherein the guide area is formed on a base plate of the receiving element and on a surface area adjacent to the guide area the base plate is formed a flat light emission area. By such a configuration, a receiving element is created, which is designed to be multifunctional. In addition to its support for the shelf, it is also a light element, which allows very specific and specific illumination of the interior. It is thus possible in the area of the shelf and very local specifically on the receiving element, a light irradiation into the interior. Also, the shelf can thus be illuminated very specific. In addition, this installation of the light emission area also achieves a very space-saving realization. Further implementation or support of a separate light emission region on a vertical wall of the inner container is therefore not required. These vertical walls are thereby not peripherally loaded with other separate penetrations or the like, so that the production is easier and on the other hand, the isolation of the gap between the inner container and an outer housing is not affected.

Preferably, it is provided that the receiving element has an upper first and a second guide region spaced therefrom in the vertical direction, and in the surface region of the base plate formed therebetween the light emission region is formed. As a result, the light emission region is also arranged quasi protected from above and below by the guide areas.

It is advantageous that the surface area is formed at least 50%, in particular at least 80%, as a light emission area. Such a large percentage allows a very uniform light irradiation in the interior and on the other hand to radiate a very large amount of light. Preferably, the guide region and the base plate having the light emission region are integrally formed. As a result, the number of components is reduced and the light emission positionally possible.

Preferably, the guide region is made of a first plastic material and the base plate is formed, at least in the light emission region, from a different second plastic material. As a result, a simple 2K injection-molded part can be produced, which is locally translucent or opaque.

In particular, the base plate is formed in the light emission region as a cover for a light source arranged behind it. The base plate is then formed at least translucent at the light emission region.

The base plate can also be formed with a light-scattering structure, at least in the light emission region, whereby a more extensive and uniform irradiation of light can take place.

It can preferably be provided that a guide region has a tilt protection element and / or a pull-out stop element for a shelf. It is preferably provided that the light emission region itself is designed as a flat light source. It is particularly advantageous here that the light source is designed as an OLED film and thus as an organic light-emitting diode film. This is extremely flat and thus designed to save space and on the other hand allows a very large, even, uniform light emission. The advantages mentioned above are thereby further favored. In addition, such a configuration is relatively insensitive to the ambient conditions in the interior itself, so that a permanently reliable and robust light irradiation is made possible in the interior. It is preferably provided that in a rear area, in particular at a transition between a lateral vertical wall and a rear wall of the inner container, a cable feedthrough is formed for a cable for supplying energy to the light source. This embodiment also brings advantages in terms of a tidy and space-saving place for the energy supply of the light source. Here, too, a certain protection for the cable feedthrough is achieved by the receiving element, so that no unwanted large mechanical force is applied to the cable feedthrough even with extensive loading of foodstuffs or the like. This, too, is thus positioned wear-resistant with regard to force effects and therefore also permanently functional. In addition, such a configuration also enables a very short distance between the light source and the energy source.

It is preferably provided that the at least one guide region is designed as a guide slot. A mechanically reliable recording and the reliable smooth and jerk-free guidance of the receiving element are thereby made possible without undesirable tilting or spreading of the interior element, in particular the shelf, would occur.

It is preferred if a vertical wall has a hollow pocket which projects into the interior with respect to an inner side of the vertical wall and which is designed to receive a holding element of the holding device. The retaining element extends through at least one opening in the pocket into the interior. By means of such a configuration, this hollow pocket is formed, as it were, integrally integrated into this vertical inner wall, which, on account of its shape, enables the holding of a retaining element to be mechanically stable on the one hand, and enables it to sunk on the outside of the vertical wall, on the other hand. As a result of this embodiment, attachment of further components to the retaining element can be effected easily and nevertheless stably in the interior. On the other hand, the outer side of the vertical wall is at least partially filled by the arrangement of the holding element in the pocket, so that also here other functionality is achieved.

In particular, it is advantageous in the context that vacuum insulation elements that can be mounted in a space between the inner container and an outer housing, even at the locations where the bag is arranged with the holding element, can be placed and attached substantially flat. Thus, even large-scale vacuum insulation elements can be arranged virtually flat on this outside of the vertical wall in the region of the pocket. Another introduction or foaming one of the between the Vacuum insulation element and the outside of the vertical wall resulting space is no longer required.

It is preferably provided that the pocket is formed integrally with the vertical wall. As a result, a component reduction is achieved. On the other hand, this ensures a permanent positional stability of the bag to the vertical wall and reduces assembly costs. In particular, the inner container is formed with the bag made of plastic.

It is preferably provided that the retaining element fills the pocket, in particular an outer side of the retaining element is flush with adjacent to the pocket surface areas of the interior facing away from the outside of the vertical wall. The above-mentioned advantages with respect to the attachment of a vacuum insulation element on this outer side are thereby particularly favored. It is preferably provided that the retaining element with at least one fastening part for fastening a receiving element for an interior element, in particular a shelf, extends through the at least one opening in the pocket. The holding member thus extends on both sides of the vertical wall and thus the pocket, which allows a space-minimized and compact design, on the other hand, the required for the attachment of a receiving element on the holding elements areas of the holding element are easily accessible in the interior exposed and allow stable attachment.

It is preferably provided that the fastening part is designed like a bar. The receiving element can thus be plugged or latched to this bar-like fastening part. This beam-like configuration is also mechanically stable and thus can easily absorb corresponding weight forces.

It is preferably provided that the holding element has a base plate, and the fastening part is arranged at a distance from edges of the base plate. This attachment part is thus offset inwardly from the edges defining the dimensions of the base plate. This will be a relatively uniform attachment allows the holding element in the pocket, so that a corresponding support of the base plate is reached on the outside of the bag.

In a further embodiment, it is provided that the retaining element with at least two fastening parts for fastening a receiving element for an interior element, in particular for a shelf, extends through in each case one of at least two openings in the pocket. In such an embodiment, another concept of attachment of the retaining element in the pocket on the one hand and another attachment concept of the receiving element on the retaining element on the other hand is based. Here, too, on the one hand, the mechanically stable attachment of the retaining element on the pocket and the receiving element on the retaining element is achieved. The two fasteners are strip-like or plate-like and extend parallel to each other in the horizontal direction. In particular, they are at a maximum distance from one another when viewed in the vertical direction, so that here too the holding functionalities, as mentioned above, are favored.

It is preferably provided that the openings are horizontally oriented slots, which are formed parallel and spaced from each other.

In particular, it is provided that the holding element is U-shaped in cross-section and extend the U-legs through the two said openings into the interior.

In an alternative embodiment can also be provided that the holding element is formed in cross-section L-shaped and extends through the L-leg through then preferably only an opening in the pocket in the interior.

The holding element is preferably formed in one piece and may be made of plastic or metal. In particular, it is provided that a holding element for a separate receiving element for receiving an interior element, in particular a shelf, is arranged on the inside and is connected to the holding element. The holding element thus acts in particular as a carrier element for this interior side Receiving element. At this receiving element is then the interior element, which is in particular a shelf, preferably non-destructively releasably attachable.

Such a configuration with a plurality of separate components of the holding device, their positional arrangement can be made extremely compact and on the other hand, the mechanical connection of the components to each other easily and little effort possible.

It is preferably provided that the receiving element is designed as a rail, which has a guide slot for receiving a side edge of the interior element on the side facing the interior. By such a configuration with a guide slot, the interior element, in particular a shelf, easily inserted and then moved horizontally guided safely without tipping would occur. In an advantageous embodiment, it is provided that the receiving element has two separate guide slots, which are viewed in the vertical direction of the household refrigerating appliance one above the other and spaced from each other and extend in the horizontal direction parallel to each other. This allows a shelf to be mounted and inserted at different altitudes of a single receiving element.

It is preferably provided that a holding element is completely covered on the inside by an interior element. The retaining element is thereby protected from being struck and from contamination.

It is preferably provided that a guide slot has a lower clear height in a receiving element in a front first area than in a rear area, whereby a pull-out stop for the interior element is formed. Integrated in this guide slot is thus virtually realized by a simple configuration, namely a slot height change, such a pull-out stop element.

It is preferably provided that the receiving element has a light emission area. Such a configuration can be a very specific local Positioning of the light emitting region are made possible, whereby an illumination of the interior can be made more targeted and uniform. It can be provided in the context that one or more light sources are spaced from the light emission region, optionally also arranged inside the room and the light of these light sources are then passed for example via optical fibers to the light emission area and emitted. In an advantageous embodiment, it is provided that the light emission region is designed as a light source and is thus arranged almost directly in the interior on the receiving element.

In a further embodiment, it can also be provided that the guide regions formed as guide slots in the receiving element in its vertical position and thus in the vertical direction can be changed. In particular, it may be provided in the context that a one-piece receiving element as a whole is variable relative to the vertical wall in the vertical position. Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively specified combination but also in other combinations or alone, without the frame to leave the invention.

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

In Fig. 1, a household refrigerator 1 is shown, which is designed for receiving food. The household refrigerator 1 may be, for example, a refrigerator or a freezer or a combined refrigerated freezer. The household refrigerating appliance 1 is designed to hold household-standard quantities of food, such as food and drinks. It comprises an interior 2, which is designed to hold the food. This interior 2 is bounded by an inner container 3, wherein this two opposite lateral vertical walls 4 and 5, a rear wall 6, a top wall 7 and a bottom wall 8 has. At the front, the inner container 3 has a feed opening, which can be closed by a door 9.

In addition, the household refrigerating appliance 1 comprises an outer housing 10, which surrounds the inner container 3, wherein between the inner container 3 and the outer housing 10, a gap 1 1 is formed. In this intermediate space 1 1 at least partially vacuum insulation elements are arranged so that a thermal insulation is achieved.

In the interior 2 shelves 12 and 13 are shown in number and position only by way of example. On these foods can be applied and stored. The shelves 12 and 13 are held on the lateral vertical walls 4 and 5, to each holding devices are formed.

In Fig. 2, the household refrigeration appliance 1 is shown with a view into the interior 2 in a perspective view. A view of the lateral vertical wall 4 is shown, in which case a receiving element 15, which is arranged in the state mounted in the interior 2 and is designed to receive an interior element designed as a shelf, is formed on an upper holding device 14. The partitions 12 and 13 shown in FIG. 1 in position and in number only schematically and by way of example are likewise shown again in FIG.

The holding device 14 has in the embodiment shown two separate holding elements 16 (FIG. 4), which are arranged with a base plate 17 outside the interior space 2, and with a fastening part 18, which is integrally formed on the base plate 17, in the interior 2 extend. For this purpose, the lateral vertical wall 4 includes pockets 19 and 20, which are integrally formed in the vertical wall 4.

As shown in a sectional view in the x-y plane in FIG. 3, the pocket 19, which is also representative of the analogous pocket 20, is formed as a hollow pocket formed in the direction of the interior 2 with respect to an inside 4a of the vertical wall 4. The cavity 19 a is provided in the context for receiving the retaining element 16. In particular, it is provided that, in the assembled state of the retaining element 16 in the pocket 19, the fastening part 18 extends through an opening 19b in the pocket 19 into the interior 2. In addition, it is provided that the base plate 17 is dimensioned so that in the inserted state, the cavity 19 a is filled to the maximum, and a rear side 17 a, which faces away from the inner space 2, is preferably arranged flush with an outer side 4 b of the vertical wall 4. A vacuum insulation element 28, shown by way of example, abuts the outside 4b and the back 17a over its entire surface.

In Fig. 2, the rail-like configuration of the receiving element 15 is shown. This can be for example a one-piece plastic part. As can likewise be seen in the embodiment in FIG. 2, the receiving element 15 comprises a base plate 21, on which two guide regions formed as guide slots 22 and 23 are formed. The guide slots 22 and 23 extend in the horizontal direction and thus in the z-direction and are arranged parallel to and spaced from each other. Each guide slot 22 or 23 is bounded by a respective upper slot wall 22a or 23a and a lower slot wall 22b or 23b. The base plate 21 has, viewed in the vertical direction between the guide slots 22 and 23, a surface area 24 which comprises an inner side facing the inner space 2. This surface area 24 may be at least 50%, preferably at least 80%, as the light emission area 25, in particular as the light source itself. Preferably, an OLED film is arranged in the context.

In Fig. 5 an enlarged view of the embodiment in Fig. 2 is shown, in which case the receiving element 15 on the holding elements 16, as in the pockets 19 and 20 are each installed as separate parts, is arranged. The receiving element 15 completely covers the fastening parts 18 and is plugged or engaged on these fastening parts 18.

In addition, it can also be seen in FIG. 5 that a clear height of the guide slots 22 and 23, dimensioned in the y-direction, varies at least once over the length, which is dimensioned in the z-direction. In a front region 22c, this clear height is smaller than in a rear region 22d. The same is provided in the areas 23c and 23d. For this purpose, a stop is formed at a stage 22e or 23e, which serves as a pull-out stop element. A side edge 12a of the compartment divider 12, which is arranged and guided in the guide slot 23 in the example according to FIG. 5, thus abuts on this step 23e with a thickening 12b. In the y-direction, this thickening 12b is therefore in particular greater than the clear height in the front region 23c.

In Fig. 6 is a perspective view from above of another embodiment of the household refrigerator 1 is shown. In this embodiment, the pocket 19 is formed with a horizontally formed upper slot-like opening 19c and a lower slot-like opening 19d parallel thereto. The holding element 16 is here designed as a cross-sectionally L-shaped or in particular U-shaped and in turn has a base plate 17 and at the upper and the lower edge thereof bent strip-shaped or tab-shaped fastening members 18a and 18b. In the assembled state, the base plate 17 fills the cavity 19a here, as it is also present in the embodiment in FIG. 6, and the fastening parts 18a and 18b extend through the openings 19c and 19d into the interior space 2. The receiving element 15 can also be mechanically compatible with these fasteners 18a and 18b coupled again, for example, be plugged together or locked. Again, the receiving element 15 in particular only extends without exception in the interior 2 and does not reach through the vertical wall 4 through to the outside. In Fig. 7, the assembled state of the holding member 16 is shown.

8 is a further perspective view of the household refrigerating appliance 1 for clarification, a plurality of embodiments for light emission areas, in particular flat light sources in the area 24 shown. In the upper embodiment, the area 24 is covered by 50% of the light emitting area 25. In an embodiment shown below, the coverage of the surface region 24 by the light emission region 25 is at least 90, in particular at least 95%.

In addition, it is shown by way of example that in a transition 26 between the lateral vertical wall 4 and the rear wall 6 also formed as a vertical wall, a cable bushing 27 is formed, which is designed for passage for a cable for powering the flat light source, which is an OLED film is.

In Fig. 9, a further embodiment is shown in a perspective exploded view. There is provided that not as slots but as guide pads 22 'and 23' formed guide portions are integrally formed with the base plate 21, in which case in particular the guide pads 22 'and 23' from a first, in particular opaque, plastic material, and the base plate 21, in particular at least in the light emission region 25, are formed from an at least translucent, second plastic material, so that in particular a 2K injection molded part is formed. In this embodiment, the light emission region 25 itself is not a light source, but instead forms a cover for a light source 29 arranged behind it. At least this light emission region 25 of the base plate 21 can also be light-scattering structured. Furthermore, a reflector 30 can also be arranged behind the base plate 21, so that the light of the light source 29 can be deflected and reflected in a targeted manner.

Not only in this embodiment according to FIG. 9, a pull-out stop and / or a tilt protection element for the compartment divider 12 may be formed on the guide area. By way of example, a pull-out stop 31 can be integrated into the guide support 22 'by means of a step. In the assembled final state, the base plate 21 completely covers the light source 29 and the reflector 30. The compartment divider 12 lies with its side edge 12a on the guide support 22 '.
