Description

Household refrigerating appliance with an interior in which a carrier is slidably disposed, on which a container is positioned

The invention relates to a household refrigerator with an interior which is bounded by walls of an inner container. The household refrigerator comprises a container for holding food, which is arranged displaceably in the interior.

Such embodiments for a household refrigerator, such as a refrigerator or a freezer or a combined refrigerated-freezer, are well known. Containers in the form of drawers, in which food is introduced, can usually be pulled out horizontally in the depth direction of the domestic refrigerator and inserted. For this purpose, they can be stored, for example, on storage devices which are arranged on side walls of the inner container, and guided accordingly. From WO 201 1/018352 A1, a household refrigerating appliance with a displaceable plate is known, on which containers can be mechanically coupled with play in a rear area, so that during movement of the plate the container is moved along.

It is an object of the present invention to provide a household refrigerator, in which a user-friendly handling and smooth and safe displacement of such a container is achieved.

This object is achieved by a household refrigerator, which has the features of claim 1.

A domestic refrigerator according to the invention comprises an interior which is bounded by walls of an inner container. The domestic refrigerator comprises at least one container for holding food, which is arranged displaceably in the interior. A carrier, which is formed separately from the at least one container, is displaceably mounted in the inner space and the container is disposed on the carrier so as to be non-destructively detachable. In addition, it is provided that the at least one container is movably coupled to move with the carrier. The motion coupling is in Depth direction of the household refrigerator considered at least in a front region of the container and formed at least in a front region of the carrier. This results in a highly functional and easy-to-use arrangement that allows a very user-friendly and safe motion control of the container. Even with extensive placement of at least one container with food and thus relatively high weight of the container this is still easy to pull out and push in and does not lift the front of the carrier. By such a carrier, which virtually forms a certain substructure for the container, these forces occurring can be recorded accordingly and the motion control of the entire system is still very smoothly possible by the derivation of forces on the carrier.

Also essential is the non-destructive separation and reassembly possibility between the carrier and the at least one container, so that here too high flexibility for a user is achieved with respect to the number and / or shape to change the placement of the carrier with containers. In addition, such a repeatable separation and assembly possibility, the handling of the individual components, for example, in terms of cleanability, can be increased. As a result of the movement coupling between the carrier and the container, these two components, although actually separate components, are essentially fixed in position relative to one another during displacement, so that there is no undesired slipping or dropping of the container. Such an embodiment also achieves the effect that both the container can be grasped directly by a user, and the carrier can be grasped directly, and the removal of respectively two components is then achieved simultaneously.

Preferably, the engagement element of the carrier is positively arranged in the coupled state with the recess in the container and thus accurately received or embedded therein in areas. As a result, a play-free connection and a coupled motion control without relative movement between the container and the carrier is achieved, so that, for example, no rattling noises occur. Especially in the front region such a coupling is advantageous because it can not tilt due to the play-free connection when gripping the container.

Preferably, the container has in the front region at its bottom a, in particular trough-like, depression in which a, in a front region of the carrier raised upwardly projecting, in particular strip-shaped engagement element engages in the coupled state. As a result, a particularly simple and secure connection possibility is created when placing the container, which also self-snapping coupled by the weight of the container. In particular, the bottom is formed toward a front wall of the container downwardly with an offset and the recess is adjacent to the front wall of the side facing away from the offset, in particular adjacent thereto. As a result, no undesired projection of an engagement element in the depression occurs downwards and a further stop for the engagement element is formed.

Preferably, the engagement element is a, in particular U-shaped, edge protection of a carrier plate of the carrier. As a result, a multifunctional component is created, which allows a compact arrangement of the components to each other and thereby ensures a diverse support to each other, so that also a holder and position assurance and a puzzle-like abutting and snagging is achieved.

It is preferably provided that the carrier is at least one frame on which the container is arranged. Such a configuration is mechanically relatively stable, so that a relatively symmetrical installation of the container is made possible on this frame. This can then be achieved on the one hand and uniform and smooth motion control again on the other hand even weight distribution. An embodiment of the carrier at least as a frame also allows a very stable in itself structure, which is torsionally rigid, so that unwanted distorsions in the motion implementation are prevented by this dimensional stability.

It is preferably provided that the movement coupling is designed to act in the direction of the rectilinear displacement movement of the container. Will thus this arrangement When viewed in the direction of the depth, it is pulled out in a straight line, so that no relative movement between the container and the carrier can be established in this direction. In particular, when the movement coupling acts only in the direction of this displacement effect, a relative movement is possible in the two spatial directions perpendicular thereto and thus viewed in the width direction and in the height direction of the household refrigerating appliance. This may in particular have advantages with regard to the separation of the two components and the re-assembly. In particular, it is thus provided that the movement coupling is formed only in the direction of the rectilinear displacement movement, which extends in the depth direction of the household refrigerator.

It is preferably provided that in the coupled state of the container and the carrier are arranged in a vertical direction at several points in some areas interlocking. This is then in particular an exclusively mechanically acting coupling which, on the one hand, has a very simple design with regard to its functionality, on the other hand is very heavily loaded and robust and thus is also designed to be permanently functional and wear-resistant.

It is preferably provided that the container has in a rear region in the depth direction at its bottom at least one mechanically acting engagement element, which is designed for coupling with an engagement region formed in a rear region of the carrier. Here, as it were, a kind of mechanical gearing is created between the objects, which thus shows a certain overlap of the engagement element and the engagement region, in particular in the vertical direction. Due to the additional rear coupling, the movement coupling is further improved and formed at the maximum spaced exposed locations.

It is preferably provided that the engagement element is formed projecting downwards from the bottom of the container and engages in an engagement region of the carrier designed as a depression. In such an embodiment, a simple one-piece molding of the engagement element is made possible at the bottom of the container. As a result, the engagement element is fixed mechanically stable and can also be coupled robustly with the engagement region. An inverse embodiment can also be provided in which a raised upwardly-disposed engagement element is then formed in a rear region of the carrier, which engages in the coupled state with the container in a recess formed in the transition between the rear wall and the bottom of the container. In such a configuration, however, the volume of the container in which food can be taken is then possibly reduced.

It is preferably provided that the engagement element is formed at the transition between the bottom and a rear wall of the container. By such a configuration, it is arranged relatively space-saving and it does not prevent a user or when handling the container, it is not in the way.

It is preferably provided that the engagement element in this rear region of the container extends over at least 50%, preferably at least 80%, of the width of the container. As a result, a very extensive and not only punctual mechanical coupling with the carrier is achieved. An undesirable loosening or slipping out of the container from the carrier is thereby prevented.

By means of an embodiment, then, in addition to the coupling which is formed in the front region between the carrier and the container, a coupling is additionally produced in the rear region. In the displacement movement, the position fixation of the two components is improved to each other. Just when, for example, a random placement of the container is done with food, are placed in the heavy food only in the front of the container, thereby folding up the container in the rear area will not be detrimental effect on decoupling, since then still in the front Area a coupling between the container and the carrier would be maintained. Also in the front region may preferably be provided that extends the recess by at least 50%, preferably 80%, of the width of the container in the width direction.

In an alternative or possibly additional embodiment it can be provided that the coupling between the container and the carrier is formed by magnetic holding forces. For this purpose, magnets can explicitly on the container and / or be formed the carrier. Preferably, these can also be designed analogously to the previously explained embodiments in a rear area and / or front area. Optionally, advantageous locations here are the respective four corners of the bottom of the container. As an alternative to explicit embodiments with magnets, it is also possible to provide magnetically interacting materials, such as, for example, ferromagnetic metal.

In order to avoid any interference of these magnets or ferromagnetic metals by moisture in the interior, they can also be arranged completely embedded in the particular plastic material of the container and / or the carrier.

It is preferably provided that the carrier is a plate. In this embodiment, not only a frame is provided with a central opening, but actually a full-surface plate. The setting up of several containers on this carrier is favored.

It is preferably provided that the coupling of the container with the carrier by lifting the container in the vertical direction is solvable. This is a very simple and user-friendly design, since no comprehensive and previously complex learning motion sequences and operating scenarios are carried out by a user.

Preferably, it is provided that at least two containers are arranged side by side at the same height in the interior and arranged to be non-destructively detachable on at least one carrier. By gripping and pulling out of the carrier thus at least two juxtaposed containers can be pulled out simultaneously. Likewise, however, this is also possible if a user directly a container, for example, on the handle, engages and pulls out. Likewise, it is also possible that at the same height two separate and independently displaceable carrier are arranged, on each of which at least one container is positionable and bewegungskoppelbar with the respective carrier. It can be provided that the carrier is mounted displaceably by a roller bearing or a guide rail device. The ease of movement guidance is favored.

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. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained. Embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

Embodiment in Figure 2 with a decoupled container.

Fig. 4 is a perspective view of the view in Fig. 3; and

Fig. 5 is a perspective sectional view of a mechanical coupling between a container and a carrier in a rear region of the components. In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1, a household refrigeration appliance 1 is shown in a perspective view, which may be, for example, a refrigerator or a combined refrigerated-freezer.

The household refrigerator 1 comprises a housing 2, on which an inner container 3 is arranged. The inner container 3 defines an interior space 4, can be introduced into the food for storage and preservation. The inner container 3 comprises two lateral vertical walls 3a and 3b and a rear wall 3c. In addition, the interior 4 is limited by an unmarked floor and an unmarked ceiling, which also represent walls of the inner container 3. The household refrigerator 1 further comprises a further separate interior 5, which is separated from the upper interior 4.

The upper inner space 4 can be closed by a door 6, whereas the lower inner space 5 can be closed by a door 7 independently of the door 6.

In the interior 4, a device 8 is arranged, which comprises a first container 9 and a second container 10. The two containers 9 and 10 are each designed as drawers or trays and designed to hold food. The two containers 9 and 10 are also arranged in the exemplary embodiment on a common carrier 1 1.

The support 1 1 is formed in the embodiment as a plate, which can in the depth direction and thus in the z direction of the household refrigerator 1 and thus also of the interior 4 back and forth. For this purpose, an unspecified marked guide device is formed, which is designed for example as a roller bearing or as a guide rail device. It can be provided in the context, for example, that 1 1 rollers are formed on the underside of the carrier, which then run on guides which are arranged on a further plate formed underneath or which are formed on the walls 3 a and 3 b. FIG. 2 shows, in a perspective, partially sectioned illustration, the domestic refrigerator 1 in the region of the device 8. The container 9 is shown cut as well as the carrier 1 1.

In Fig. 2, that state is shown in which the container 9 is shown with the carrier 1 1 in the mechanically coupled state. For this purpose, it is provided that in a rear region 12 of the container 9 at an interface between a bottom 13 and a rear wall 14 of the container 9, an engagement element 15 is formed, which is integrated into the container 9. However, it can also be designed as a separate part and be glued to the floor 13, for example.

The engagement element 15 is a downwardly and thus in the negative y-direction extending, hump-shaped element. It engages in the coupled state in a groove-like depression, which represents an engagement region 16 of the carrier 1 1 in the rear region 1 1 b. The engagement region 16 and the engagement element 15 couple in a mechanical manner to the effect that a movement coupling between the container 9 and the carrier 1 1 is achieved in the rectilinear direction of movement and thus in the z-direction. The container 9 and the carrier 1 1 thus overlap each other in the vertical direction (y-direction) and are virtually hooked. In particular, such a coupling is provided only in this direction. In the x and y direction then the coupling does not work.

In the embodiment shown in Fig. 2, an exclusively mechanical coupling is provided, and the container 9 and the carrier 1 1 engage in some areas in the y-direction and thus in the vertical direction into each other. In particular, it is provided that the engagement element 15 and the engagement region 16 extend over the entire width and thus an extent in the x-direction of the container 9. As can be seen, a rear boundary wall 17 of the engagement region 16 is formed in the vertical direction further upwards, so that in this context also a rear stop for the container 9 is formed. The upward extension of the wall 17 is higher than an altitude, on which the flat plateau of the carrier 1 1, on which the bottom 13 is located.

In addition, it is provided in the exemplary embodiment that in a front region 18 of the container 9 and in a front region 1 1 a of the carrier 1 1 a further, in particular exclusively mechanically acting coupling is provided. This comprises a groove-like recess 19 in the bottom 13, in which an upwardly projecting, in particular strip-shaped engagement element 20 of the carrier 1 1 engages. Here, too, provision is made in particular for the depression 19 and the engagement element 20 to extend over substantially the entire width of the container 9.

The engagement element 20 is an edge protector for a carrier plate 23 of the carrier 11. It surrounds an edge or an edge of the support plate 23 U-shaped and lies with a leg of the U-shape embedded in the recess 19. In particular, a positive arrangement of extending into the recess 19 part element of the engagement member 20 is formed. As can be seen, the bottom has an offset 29 downwardly, which then opens into a front wall 28 of the container. In the depth direction on the side facing away from the front wall of the offset 29, the recess 19 is formed.

The plate-like support 1 1 is coupled to the rectilinear motion control in the z-direction via the possibilities of a roller bearing or a guide rail device already mentioned by way of example with a plate 21 formed under the support 11. This has exemplary guides 22. With regard to the dimensions of the support plate 1 1 it should be mentioned that the planar design is at least as large as the bottom 13 of the container 9. In the embodiment it is provided that two containers 9 and 10 are present, and that the carrier 1 1 is a planar Has extent that corresponds to at least the surfaces of the bottoms of the two containers 9 and 10. At the top, the container 9 is covered in the inserted state in its inserted end position by a further plate 24, for example a glass plate.

It can be provided that the support 1 1 is at least partially made of glass, in particular a support plate 23 is glass, which is surrounded by a support frame circumferentially, in which then behind the engagement portion 16 is formed on the one hand, and through which on the other hand the front Engagement element 20 is formed. The same is shown in Fig. 2 and seen in the sectional view.

Preferably, it is provided that the separation of the container 9 is achieved by the carrier 1 1 by a simple lifting in the y direction. This is shown in the illustration in FIG. 3. In this perspective view, which in turn is shown sectioned in the region of the container 9 and the carrier 11 in the y-z plane, the separated state of the container 9 from the carrier 11 is shown. The containers 9 and 10 are here drawn in the negative z-direction to the outside, so that the accessibility to the respective receiving spaces is made possible.

By the two separate containers 9 and 10 are arranged on a common carrier 1 1, a simultaneous and uniform displacement by means of the displaceably mounted carrier 1 1 takes place in each case.

In Fig. 4 is a perspective view of the device 8 is shown, in which a side view can be seen and thus also the guide device, as shown by way of example in Fig. 4, can be seen. By way of example, rollers are provided here, of which only one front roller 25 is shown. By way of example, four rollers are provided, which are each formed in pairs on one of the opposite sides. For the rollers 25, a tread 26 is formed and beyond also a coupling between the guide 22 and a lateral flange 27 of the carrier 1 1 is provided, as can be seen in Fig. 4. In this case, an overlapping meshing in the x direction between the components 22 and 27 is designed. Accordingly, an analogous design and coupling is also provided on the opposite side in the region of the container 10. In Fig. 5 the coupled state between the container 9 and the carrier 1 1 is shown in an enlarged view in the rear region, in which case in contrast to the representation in Fig. 2, a viewing direction is shown in the negative x-direction.
