Description

Domestic refrigerating appliance with a sliding bucket for a food container that can be placed thereon

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

Such embodiments are known for example from EP 2 241 846 A2 or DE 35 057 57 A1. In the local designs, however, it is provided that on side walls of the inner container laterally and the interior open towards guide slots are created, in which the container engages with horizontally and thus laterally projecting guide elements and can be moved accordingly in the depth direction of the household refrigerator. In these embodiments, on the one hand, relatively complex guide slots may be required to allow insertion and advancement of the container. In addition, the laterally and thus horizontally open guide slots must be very stable on the side edges of the inner walls and in particular that one horizontal web which limits this guide slot down, also be mechanically highly resilient. This brings particular disadvantages in the production, if the inner container integrally molded, for example, deep-drawn. The cavities resulting from this must be poured out in order to enable the mechanical stability of these protruding into the interior webs then sufficient.

In addition, in the displacement of the container with the relatively small guide elements, a spreading occur, so that the sliding movement jams or can be continued only very jerky and thus user-friendly.

It is an object of the present invention to provide a household refrigerator, with which a smooth movement of the container is made possible and a simple design and stable durable construction is achieved. 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 bounded by walls of an inner container. In addition, the domestic refrigerator comprises at least one container for holding food, which is arranged displaceably in the interior. An essential idea of the invention is to be seen in that the household refrigerating appliance has a displacement device for the container, which has at least one sliding step extending upwards and thus in the vertical direction in the direction of the container. The container has a downwardly extending to the sliding step towards receiving, in which the sliding step in the attached state of the container extends into it. It is thus provided an embodiment in which quasi the container is not guided laterally in a guide slot and laterally extends into it, but is quasi guided from above on a vertically oriented and in this respect vertically upwardly exposed sliding stage. The container thus sits quasi in particular sled-like on the sliding stage and can thus be moved very easily and easily in the horizontal direction and thus pushed into the inner container and pulled out. Such a refinement with a sliding step improves the motion guidance and, moreover, also creates a construction which is mechanically easy to couple, since the container can be placed, as it were, only from above, and the sliding step in this respect is arranged very clearly visible and exposed.

In addition, the mechanical coupling of the sliding stage with the recording is maintained almost always by the weight of the container and even then, even if the container is equipped with food, this even favors.

It is preferably provided that the sliding step is at least partially covered over its length from above by the recording. As a result of this configuration, no unnecessary installation space is required in the width direction of the household refrigerating appliance, since the displacement chute is arranged, as it were, below the container and thus, as it were, within the dimensions of the container in the width direction. Preferably, it is provided that the shift runner is surrounded by the receptacle from above like a roof. This is a particularly noteworthy embodiment, since thus virtually an undesirable lateral relative displacement between the container and the sliding stage is prevented. A quasi-lateral slipping of the container from the sliding stage is prevented. Through this recording with its roof-like design quasi a downwardly open groove and guide slot is created, which allows for a vertical lowering of the container a simple coupling with the sliding stage.

A horizontal lateral coupling and introduction of the displacement stage in the recording is excluded.

It is preferably provided that the receptacle in cross-section perpendicular to a longitudinal axis of the displacement stage has an inverted U-shape or an inverted V-shape. Preferably, this shape specification is adapted to the geometry of the displacement stage in a cross section perpendicular to the longitudinal axis of the sliding stage. As a result, the largest possible possible coupling and as large as possible abutment between the surface of the sliding stage and the surface of the recording can be achieved. By a U-shape quasi one of the sliding block facing cornerless contour of the recording is created, so that no undesirable Verspreizungen or jamming occur here. A very smooth and jerk-free motion control of the container is made possible. In addition, the cleanability is improved by such a design.

It is preferably provided that an inner leg of the U-shape facing the receiving space of the container extends further downwards in the vertical direction, like an outer leg facing away from the receiving space. The position stabilization in the motion control is thereby further improved. For a virtually outwardly slipping over of the container on the displacement stage in the direction of a side wall of the inner container is made even more difficult.

It is preferably provided that the displacement step is formed on a protruding into the interior pedestal. As a result, the shift bucket is fixed mechanically stable and arranged and this pedestal can also be a mechanically stable Connection made in particular to a side wall of the inner container. Even if a sliding stage is made relatively filigree and thin, nevertheless a mechanically robust connection and also a high torsional rigidity are achieved.

It is preferably provided that the pedestal extends below a bottom of the container and thus, viewed in the width direction of the household refrigerating appliance, a horizontal overlap between the container and the pedestal is formed.

Preferably, it is provided that in the coupled state between the container and the displacement stage of the inner leg of the U-shape is seated on an upper side of the pedestal next to the displacement stage. Again, this is a particularly advantageous embodiment, because the slipping safety of the container to the side and also an undesirable rattle in the movement guidance of the container are thus prevented. By sitting on this extended inner leg on the top of the pedestal next to the sliding stage also an additional stabilization of the motion control and thus a very straightforward motion control is achieved.

It is preferably provided that only a single displacement stage is designed for coupling to the container. It is quasi thus provided only a single-track or single-rail coupling of the container.

It can be provided that this is a sliding step, which is provided for coupling with a container, asymmetrically to an axis of the container, which extends in the depth direction of the domestic refrigerator and in the width direction of the container is a center axis, is arranged. In particular, it can be provided in such an embodiment that the sliding stage in the region of a side wall of the container and viewed in the vertical direction is thus below such a side wall of the container. However, it can also be provided that such a runner is arranged further offset inwards and, for example, viewed in the width direction extends centrally between this center axis and the side edge, which is formed by a side wall of the container, in the depth direction. In a further embodiment, however, it can also be provided that this single displacement stage, with which a container is coupled for movement to move, extends coaxially to this in the depth direction extending center axis of the container. In such an embodiment, a particularly jerk-free and spread-avoiding movement is then given.

Since usually a container is gripped approximately in the middle of a front handle which extends in the width direction, just with such in the middle position in the depth direction extending sliding stage no or little leverage between a user's point of attack on the handle of the container and the coupling point between the receptacle of the container and the Verschiebekufe occurring.

Preferably, it is provided that the receptacle of the container is viewed in the vertical direction in extension of a side wall of the container formed at this downward.

It is preferably provided that the displacement device, in particular the sliding step, has a stop, by which a distance between the container and a rear wall of the inner container is formed in the inserted end position of the container. Thus, a distance stop is formed which avoids undesired contacting of a rear wall of the container with the rear wall of the inner container. An undesirably hard impact and thus an associated undesirable noise and / or damage to the container and / or the inner container are thereby avoided. Likewise, a condensation water drain on the rear wall of the inner container is unrestricted possible.

Additionally or instead, it can also be provided that the displacement device, in particular the sliding step, has a tilt protection, with which an undesired tilting of the container in an extended, but still connected to the sliding step position of the container is prevented. As a result, the container can be pulled relatively far out without it would tip forward and fall down. Even in the loaded state of the container thereby falling forward in such a maximum extendable position is prevented. A Such anti-tipper device can be formed, for example, in that the sliding step has at least one specific position along its longitudinal axis an engagement region, in which then engage, for example, hook-shaped or clamp-shaped elements on the inside of the receptacle and possibly lock there. By this configuration it is achieved that a vertical relative movement of the container is prevented to the sliding step at this Verraststelle, on the other hand, however, a decoupling in the horizontal depth direction of the household refrigerator can be easily solved again when a horizontal displacement into the interior takes place. For this purpose, these engagement elements on the inside of the receptacle in the depth direction deformable or otherwise be designed to be flexible, be formed stiff in the vertical direction and thus in the vertical direction. In addition, a variety of other mechanical couplings are also provided, which allow such a tilt protection device.

In addition to purely mechanical possibilities that allow such a tilt protection, can also be achieved for example by a magnetic holding force such a tilt protection can be achieved.

In addition, it can also be provided that the displacement step is at least in a front region, in which then the anti-tipper is to act, in a cross section perpendicular to the longitudinal axis of the displacement stage, for example, L-shaped or T-shaped or mushroom-shaped. Here too, quasi underreaching by corresponding elements on the inside of the receptacle can provide a tilt protection.

It is preferably provided that the displacement device has a plate, on the upper side of which the displacement step is formed. This plate is particularly advantageous because it can extend over the entire width of the interior and thus holds a very extensive mounting option with the inner walls of the inner container. In addition, such a plate is designed very dimensionally stable, so that even the trained thereon shift rails remain dimensionally stable. Last but not least is possible by such a configuration as a plate, the circumferential setting it up the container and in addition to the coupling with a sliding stage at other locations a mechanical contact with such a plate possible. This also allows the weight forces generated by the container can be very uniform be derived and the plate can be used as a sufficient and robust carrier.

It is preferably provided that the plate can be removed from the interior in a non-destructive manner. This brings advantages in terms of cleaning and accessibility to other areas of the interior, which may be covered by this plate.

It is preferably provided that the plate is arranged without assembly with at least one container as a shelf in the interior. As a result, it is multifunctionally usable and can be used individually and depending on the situation.

Preferably, it is provided that on an upper side of the plate adjacent to the side edges extending in the depth direction of the household refrigerating appliance each a shift stage is formed and on the plate two containers are arranged, one of which only with the first shift stage and the other only with the second shift stage is coupled. Independently of one another, two separate containers can thus be moved very easily and positioned on such a displacement device. Both containers can then also very easily hooked and guided from above into the respectively provided displacement stage. The sliding stage is used in all embodiments, thus thus as a single-track track, on the quasi from above the container can be placed as a wagon and guided along the sliding stage.

Advantageously, it is provided that the displacement device in the design of the pedestal as a plate having a support plate which may be formed, for example, glass or other transparent material, which is at least partially circumferentially, in particular completely encircling, bordered by a frame, wherein on This frame is then formed in each case a sliding block in an advantageous embodiment of the opposite side frame parts.

In particular, it is then provided that the frame is integrally formed at least on the side frame parts with the sliding runners, for example made of plastic. 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 combinations of features 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 in isolation, 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:

Fig. 1 is a perspective view of an embodiment of a household refrigerator according to the invention;

Fig. 2 is a sectional view through an embodiment of a on a

Sliding stage stored container for holding food; and

Fig. 3 is a perspective view of an embodiment with two separate containers on each shift runners.

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

In Fig. 1 a household refrigeration device 1 is shown in a perspective view, which may be, for example, a refrigerator or a combination refrigerator-freezer. The household refrigerator 1 comprises a housing 2, in which an inner container 3 is arranged. The inner container 3 is limited with its walls an upper interior 4 and in the embodiment, a lower interior 5. These includes the Inner container 3 vertical side walls 3a and 3b, a rear wall 3c and an unspecified ceiling wall and a bottom wall.

The interior 4 is closed by a door 6, which is posted on the housing 2, whereas the lower interior 5 can be closed by a separate door 7.

In the interior 4, a device 8 is arranged, which in the exemplary embodiment has two separate containers 9 and 10 in the vertical direction and thus in the y-direction of the same altitude. These two containers 9 and 10 are arranged side by side in the width direction and thus in the x direction of the household refrigerating appliance 1. They are each designed to hold food and are especially drawers or trays.

The two containers 9 and 10 are slidably mounted in the depth direction and thus in the z-direction of the household refrigerating appliance 1, to which a displacement device 1 1 is provided. The displacement device 1 1 will be explained in more detail below, reference being made to the sectional view in Fig. 2. FIG. 2 shows a sectional view of the device 11 in the x-y plane. Here, the container 9 is shown, which is shown with two vertical side walls 12 and 13 and a rear wall 14. In addition, a bottom 15 is formed. The displacement device 1 1 comprises a pedestal 16, which is designed as a continuous plate and which extends over the entire clear width of the inner space 4 between the side walls 3 a and 3 b. On an upper side 16a of this pedestal 16, in the exemplary embodiment adjacent to an end 16b facing the vertical side wall 3a, a sliding step 17 extending vertically upwards is formed in one piece. The sliding step 17 extends in a straight line in the z-direction and is formed in the form of a strand like a line.

In the exemplary embodiment it is provided that the plate 16 is formed from a support plate 18 and an at least partially, in particular completely encircling frame 19. The support plate 18 may for example be made of glass, whereas the enclosing frame 1 9 is preferably made of plastic. On an upper side 19 a of this plastic frame is integrally formed with the raised upwardly extending sliding step 17 is formed. The sliding step 17 thus extends upward in the direction of the container 9, which is shown in Fig. 2 in the attached or coupled state with the sliding stage 17. It is envisaged that only this one single shift step 17 is provided for the mechanical coupling with the container 9 to its displacement guide. In this connection, in the exemplary embodiment shown, the displacement cam 17 is arranged asymmetrically with respect to a center axis A extending perpendicularly to the plane of the figure and thus in the z-direction, which is just in the middle in the x-direction of the container 9 with respect to the width. It can also be provided in a further embodiment, that this sliding step 17 is positioned closer to this center axis A. It can also be provided that the displacement stage 17 is arranged coaxially to the axis A. A longitudinal axis of the displacement step 17 extends in the z direction, so that in FIG. 2 a sectional view perpendicular to this longitudinal axis is shown. For mechanical coupling of the container 9 with the sliding stage 17 is a belonging to the displacement device 1 1 receptacle 20 is provided. This has in the exemplary embodiment in the section perpendicular to the longitudinal axis of the displacement stage 17 an inverted U-shape and is formed in the vertical direction and thus in the y-direction in extension of a lower end of the side wall 12. It is open in the vertical direction down towards the sliding step 17 and in particular closed to the side (in the x direction). As can be seen in the situation shown in Fig. 2, the sliding step 17 engages from below into this receptacle 20, so that almost the receptacle 20 covers the sliding step 17 from above hood-like or roof-like and this also surrounds, so that in y Direction an overlap between the displacement stage 17 and the receptacle 20 is given. An undesired shift in the x direction is thereby prevented.

As can also be seen, the U-shape of the receptacle 20 shown in this cross section has an outer leg 22 facing away from an inner space 21 of the container 9 and an inner leg 23 facing the inner space 21.

As can be seen, the two legs 22 and 23 have different lengths in their extension in the y direction. The inner leg 23 is longer in this context and extends in the y-direction further down as the outer leg 22. In addition, it is partially stepped and formed with a lower leg end 24 on the upper side 16 a of the support plate 16. Starting from this low point, the bottom 15 then forms again in a stepped or cascaded form upwards, until a relatively large plateau is reached. Viewed in the width direction is then shown on the opposite side and thus the side wall 13, an analogous embodiment of the bottom 15 with also a further recording, which is not further provided with a reference numeral. However, it is analog and in particular symmetrical to the receptacle 20 formed to this center axis A. This provides the possibility that the container 9 can not only be placed and coupled in the z-direction left shift 17 and coupled, but also on a viewed in the x-direction right-hand further shift shoe 25 is placed, however, far enough away that the container 9 can not simultaneously couple with both skids.

By such a configuration with a sliding step 17 accessible from above, on the one hand a very smooth motion control and mechanical coupling is achieved, on the other hand a high mechanical load with a container 9 and / or 10 allows. Moreover, according to the embodiment in FIG. 2, it can also be seen that, in the width direction, the displacement step 17 extends, as it were, in a direct extension below the side wall 12, so that no widening of the entire device 8 occurs here as well.

In addition, it is provided that the displacement device 1 1, in particular the sliding step 17, has a stop, through which a distance between the container 9 and a rear wall 3 c of the inner container 3 in the inserted end position of the container 3. Additionally or instead, it is also provided that the displacement device 1 1, in particular the sliding step 17, has a tilt protection, with which a tilting of the container 9 in an extended, but still connected to the displacement stage 17 position of the container 9 is prevented. The displacement device 1 1 with its pedestal 16 is preferably non-destructively detachably mounted on the side walls 3 a and 3 b and optionally also on the rear wall 3 c. If the plate 16 is not equipped with a container 9, 10, it also preferably serves as a shelf, so that other objects can be positioned thereon.

In the embodiment of the device 8 shown in FIG. 3, an assembly with both containers 9 and 10 is provided, in which case the container 9 is coupled with the left-side displacement step 17 and the container 10 is coupled with the right-side displacement step 25 and extends in the z-direction. and can be pushed, and this can be done independently of the respective other container.

As can be seen, the skids 17 and 25 extend freely accessible raised to the top, so that the positioning of the container 9 and 10 is very easy and also the removal can be done very quickly and user-friendly.

As can be seen also in the illustration in FIG. 2, the container 9 is seated directly on the upper side 16a with the receptacle 20, which is coupled to the sliding step 17. Due to the flat and plate-like shape and the positioning of the container 9 is very easily possible, and also from above through the container 9 formed on the displacement device 1 1 weight force is best distributed here. The shape and thus the cross-sectional contour of the displacement stage 17, 25 is preferably adapted to the inner contour of the receptacle 20, so that a low-noise and smooth and smooth and low-wear motion control of the container 9 is possible.
