[0001] The invention relates to a household refrigeration appliance with at least one storage compartment for food. This storage compartment is bounded by the walls of the appliance. Furthermore, the appliance has at least one tray for holding the stored goods. The appliance also includes a guide system. The tray is slidably arranged within the storage compartment by means of this guide system. It is extendable and guided or mounted in a slidable manner in the depth direction of the appliance. The guide system includes a guide unit. This unit is arranged on at least one of the walls that bound the storage compartment.

[0007] Another state of the art is disclosed in document EP3954958A1.

[0008] The object of the present invention is to create a household refrigeration appliance in which the positioning of the tray during movement is improved, and in which an extended position of the tray is more easily adjustable.

[0009] This problem is solved by a household refrigeration appliance which has the features according to claim 1.

[0010] The invention relates to a household refrigeration appliance according to claim 1, comprising at least one receiving compartment for food. This receiving compartment is bounded by the walls of the household refrigeration appliance. Furthermore, the household refrigeration appliance has at least one tray for receiving stored goods. The household refrigeration appliance also has a guide system. The tray is slidably arranged within the receiving compartment by means of this guide system. It is extendable in this respect and is guided or mounted so as to be slidable in the depth direction of the household refrigeration appliance. The guide system includes a guide unit. This is arranged at least on one of the walls that bound the receiving compartment. The household refrigeration appliance additionally has a tilt protection and / or extension stop device. This tilt protection and / or extension stop device limits the extension and / or tilting of the tray when it is extended.

[0011] The tilt protection and / or extension stop device has a stop element on the tray side. This stop element is designed to abut, in particular to make direct contact, with a counter-stop element external to the tray when the tray is pulled forward in the depth direction of the domestic refrigeration appliance. This stop element is arranged, in particular, as a free cantilever and projecting laterally from the tray in the width direction. In the extended position of the tray, it is positioned to directly abut an external counter-stop element. This is such that the tilt protection and / or extension stop is then formed. The tray also has a stabilizing element that is distinct from the stop element on the tray side. This stabilizing element is connected to the stop element on the tray side. In particular, it is directly connected to the stop element.Furthermore, the stabilizing element terminates on a section of the tray that differs from the tray-side stop element. This also stabilizes the tray-side stop element. With this type of domestic refrigerator, the tray-side stop element is now mechanically stabilized and supported. This allows it to be positioned in an exposed location, enabling direct coupling with the counter-stop element external to the tray. Simultaneously, the stabilizing element provides a mechanical connection to other components of the tray. This also ensures that forces acting on the stop element when the drawer is in the extended position are absorbed and dissipated more effectively. Undesirable bending or even breakage of the stop element is thus significantly reduced.Even with relatively large trays that can be fully loaded with stored goods, this concept improves the absorption of the corresponding leverage and torsional forces acting on the stop element. In this extended position, the tray is fully extended forward in the depth direction, but still connected to the guide unit. In this relatively exposed forward position, the tray cantilevers freely forward. Due to the weight, the tray tilts around a laterally oriented tilting axis. To better absorb and dissipate these forces, a stabilizing element is provided.

[0012] In particular, this stabilizing element can also be designed as a support strut. In one embodiment, it is possible that this stabilizing element is directly connected at one end to the stop element on the shell side. At another end opposite this stabilizing element, it can be directly connected to the aforementioned shell part.

[0013] In one embodiment, the stabilizing element serves as a suspension for the stop element on the shell side. This means, in particular, that the stabilizing element extends upwards from the stop element, viewed in the vertical direction of the shell, and then terminates at the shell section that is higher than the stop element on the shell side. Thus, the stop element on the shell side is coupled to the shell section vertically by means of at least one stabilizing element. It is therefore suspended from the shell section by this stabilizing element. This is particularly advantageous for better absorbing and dissipating forces acting on the stop element from above and / or obliquely from above, especially in the extended position. Excessive downward and backward bending of the stop element in this extended position is thereby effectively prevented.

[0014] In one embodiment, the stabilizing element is formed as a plate-like strip. Viewed perpendicular to its longitudinal axis, this stabilizing element is therefore relatively thin. However, in the plane where this plate-like strip extends, it is dimensionally larger, thus providing corresponding stiffness. Furthermore, this design allows for a more direct connection, particularly over a longer distance, at the ends of this plate-like stabilizing element to the stop element on the one hand and the shell element on the other. Specifically, the stabilizing element is arranged as a suspension strap for suspending the stop element.

[0015] A stabilizing element can be created using a plate-like strip, which can be dimensioned accordingly in the width direction of the tray to be connected to the tray-side stop element over a defined length in this width direction. This stabilizes the stop element over at least a portion of its length in this width direction. Thus, the length over which the stop element cantilevers freely from a side wall of the tray is compensated for by the stabilizing element.

[0016] In one embodiment, the stabilizing element is formed integrally with the shell-side stop element.

[0017] This reduces the number of components and assembly effort, as a separate stabilizing element and a separate stop element on the shell side do not need to be mounted with additional components. Furthermore, this one-piece design creates a permanently stable connection that remains free of positional tolerances and the like.

[0018] In one embodiment, the stabilizing element terminates at its upper end on a plate web of the shell. This plate web is either the shell part or a component thereof. This creates an exposed component on the shell part, namely this plate web, to which the stabilizing element connects at its upper end. This configuration also creates a mechanically stable overall structure between the plate web, the stabilizing element, and the stop element. A very discrete contact point between the plate web and the stabilizing element is thus possible. This allows for the particularly advantageous formation of corresponding force paths to prevent unwanted movements and / or deformations of the stop element.

[0019] In particular, the upper end of the stabilizing element is formed integrally with the plate web.

[0020] In principle, one-piece forming is one-piece manufacturing. Thus, in a single manufacturing process, the stabilizing element and the stop element, and especially the plate web, are produced. This also means that in this manufacturing process, the components are formed and finished with their geometries. One-piece manufacturing therefore does not mean that these individual components are each produced separately and then subsequently joined together, for example, by gluing or similar methods.

[0021] However, in one embodiment it is also possible that the stop element and the stabilizing element are manufactured and provided as separate components and then subsequently joined together, for example by gluing or thermal welding.

[0022] In one embodiment, the stabilizing element, viewed in the width direction of the shell, extends only over a portion of the width of the stop element. Specifically, the stabilizing element extends from one end of the stop element, located at the inner end of the shell wall, over a portion of the stop element's total length. Thus, a portion of the stop element facing away from the shell wall, to which the stop element is attached and laterally projecting, is free of this stabilizing element. In this context, this portion of the stop element cantilevers freely to the side. The remaining portion of the stop element, facing the shell, cantilevers freely to the side, but is also connected to the stabilizing element in the width direction via this portion.

[0023] This embodiment offers a further significant advantage: the stop element can directly couple with the counter-stop element, particularly in the extended position. Especially with the outer side section of the stop element, the stabilizing element does not obstruct this coupling and / or tilting of the tray.

[0024] In one embodiment, the stabilizing element is positioned at a distance from an outer end of the stop element on the shell when viewed in the width direction of the shell.

[0025] Preferably, the stop element on the shell side extends, at least partially, rearward beyond the storage volume of the shell when viewed in the depth direction. This is a further advantageous embodiment. This allows the shell to be pulled forward as far as possible in its extended position, making the rear portion of the storage volume particularly accessible in this position. This is because the coupling point between the stop element on the shell side and the counter-stop element external to the shell is then positioned as far rearward as possible in the depth direction.

[0026] In one embodiment, the stop element is formed at least partially as a hollow profile. This allows for material savings, thus reducing the weight of the shell. Nevertheless, this hollow profile still achieves advantageous mechanical stability and rigidity.

[0027] In one embodiment, the hollow profile, viewed in the width direction of the shell, is open to the side and thus to the outside. This also allows for material savings. In another embodiment, at least one stiffening strut is formed in the hollow profile that forms the stop element. This stiffens the hollow profile itself. This ensures high dimensional stability when the stop element is in contact with the counter-stop element in the extended position of the shell and corresponding forces act upon it.

[0028] Preferably, at least one stiffening strut can be formed between the stabilizing element and a shell wall. This allows the stiffening strut to be connected to the shell wall at a location different from its ends, particularly an upper and a lower end. The stabilizing element is otherwise arranged at a distance from the shell wall.

[0029] In one embodiment, the stop element is designed with a sloping stop wall at the front. This sloping stop wall is preferably inclined backwards and upwards. This means that, viewed in the depth direction, the front end of this stop wall is lower in the height direction than the rear end. This achieves a very advantageous coupling with the counter-stop element external to the tray. Particularly in an extended position, where the tray is also slightly tilted downwards, this specific position of the tray can be maintained to great advantage. This allows for a larger contact area between this sloping stop wall and the counter-stop element.Linear contact points, which would then locally generate correspondingly larger force peaks, can be avoided at the stop element and still achieve the desired slight tilting position of the switch.

[0030] Furthermore, this inclined stop wall preferably also defines, and in particular limits, the maximum possible tilting position of the switch in the extension position.

[0031] In one embodiment, the stop element on the tray side is designed as the rear end, particularly extending upwards, of an elongated guide rail of the tray oriented in the depth direction. This effectively integrates the stop element into the guide rail. This also makes the stop element mechanically more stable when considered separately. In another embodiment, the section of the guide rail adjacent to the stop element in the depth direction is also designed, at least partially, as a hollow profile. The advantages mentioned for a hollow profile of the stop element apply accordingly. It is advantageous if this section of the guide rail, which is also designed as a hollow profile, has one or more stiffeners. These stiffeners can be, for example, stiffening ribs or stiffening struts. This also creates a particularly stable guide rail.In particular, this also improves the sliding of the shell. This is because the shell-side guide rail is designed to withstand high loads and can move accordingly when the shell is shifted along the guide unit. Forces acting between the guide rail and the guide unit do not impair the guide rail. This hollow profile with its stiffeners and braces also creates a truss-like structure, making the entire element, namely the guide rail, exceptionally rigid.

[0032] Even when the tray is relatively large, especially when it is heavily loaded with stored goods, undesirable impairments of the guide rail, such as deformation or tearing, can thus be avoided.

[0033] Preferably, the anti-tilt and / or extension-stop device includes an external counter-stop element. In particular, this counter-stop element limits the upward guide path for the tray in the vertical direction. This advantageously prevents the tray from moving upwards unintentionally. It also advantageously prevents the tray from tipping upwards out of the guide movement. Finally, such a counter-stop element position makes the extension position particularly easy to achieve and allows the stop element to be inclined upwards, especially upwards and forwards. Thus, in the extension position, the stop element rests against this counter-stop element at an angle, facing forwards and upwards. This position is particularly advantageous for very large and heavily loaded trays.This is because the counter-stop element can be designed to be very stable in this respect and can then also absorb the forces occurring in the extended position of the shell particularly advantageously.

[0034] In one embodiment, the counter-stop element is formed integrally with a guide rail of the guide unit, the guide rail defining the lower boundary of the guide track in the vertical direction of the household refrigerator. In particular, this guide unit is designed as a depth-oriented guide support for the guide rail. Thus, the tray's guide rail rests on the guide unit in a strip-like fashion. This larger surface contact area improves the force distribution from the tray to the guide unit, preventing local force peaks. Furthermore, this facilitates smoother operation and effectively prevents spreading or jamming.

[0035] In one embodiment, the counter-stop element has a sloping rear wall. This means, in particular, that this sloping rear wall is positioned with its front end (viewed in the depth direction) further down in the height direction than with its rear end (viewed in the depth direction). Preferably, the slope of this rear wall corresponds to the slope of a stop wall of the stop element. These identical slopes allow for a particularly large contact area between the stop wall and the rear wall in the extended position.

[0036] In one embodiment, the guide unit has a guide rail that defines a downward guide path for the tray, the guide rail featuring a local projection. This projection acts, in particular, as a tilting bearing for the tray during extension. This local projection can, for example, be dome-shaped. Such a projection, especially one with no sharp corners, ensures a continuous and uniform tilting of the tray. Preferably, this local projection is located at a forward end of the guide rail of this guide unit. The operating principle for achieving the extended position and a subsequently defined tilting position is thus particularly advantageous. This allows for smooth extension with an automatically generated tilting motion around this forward bearing point.

[0037] In one embodiment, the tray has a width of less than 60 cm, particularly less than 70 cm, preferably between 70 cm and 90 cm, and particularly between 75 cm and 85 cm. Such very wide trays can be used in very large household refrigeration appliances, such as correspondingly large refrigerators or freezers, or fridge-freezer combinations. Since this dimension also results in a significantly larger storage volume for stored goods, the total weight of the tray and stored goods can exceed 15 kg, particularly 20 kg, and especially 40 kg. The invention is particularly advantageous for such large trays in order to prevent an undesirable bending, breakage, or tearing of a stop element when the extended position is reached.

[0038] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "latitude direction", "height direction" indicate the positions and orientations given when the household refrigeration appliance is used and positioned as intended.

[0039] Further features of the invention can be found in the claims, the figures and the description of the figures.

[0040] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a perspective view of an embodiment of a household refrigeration appliance according to the invention; Fig. 2 a vertical section view through a partial area of ​​the household refrigeration appliance according to Fig. 1 with exemplary embodiments of trays in extension positions with exemplary embodiments of tilt protection and / or extension stop devices; Fig. 3 a perspective view of an exemplary embodiment of a tray and tray-external guide units; Fig. 4 an enlarged view of a partial area in Fig. 3 ; Fig. 5 an enlarged partial view of another sub-area in Fig. 3 Fig. 6 is an enlarged partial view of a section of an embodiment of a tray for stored goods; Fig. 7 is a perspective view of another embodiment of a tray with specific components of an embodiment of a tilt protection and / or pull-out stop device; and Fig. 8 is a perspective view of a section of the household refrigeration appliance according to Fig. 1 with removed shells.

[0041] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0042] In Fig. 1 Figure 1 shows a perspective view of a household refrigeration appliance 1 according to claim 1. The household refrigeration appliance is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator, a freezer, or a refrigerator-freezer combination appliance.

[0043] The household refrigeration appliance 1 has a housing 2. The housing 2 contains at least one storage compartment 3 for food. The storage compartment 3 can, for example, be a refrigerator compartment. The household refrigeration appliance 1 also has a door 4. The door 4 is movable and attached to the housing 2. It is specifically designed to close the storage compartment 3 from the front.

[0044] In one embodiment, the household refrigerator 1 can have a further storage compartment 5 for food. This storage compartment 5 can be a refrigerator compartment. This storage compartment 5 can be closed at the front by a further door 6 of the household refrigerator 1.

[0045] In receiving space 3, at least one tray for receiving stored goods is arranged. Several trays, in particular three trays 7, 8, and 9, are arranged here as an example. These trays 7 to 9 are trough-like receiving containers. They can also be referred to as food receiving trays. Trays 7 to 9 can have a width (measured in the x-direction) greater than 50 cm, in particular greater than 60 cm, in particular greater than 70 cm, and in particular between 70 cm and 90 cm.

[0046] The household refrigeration appliance 1 can additionally or instead also have at least one tray 10 in the receiving chamber 5. Two trays 10 and 11 are shown here as examples.

[0047] The household refrigeration appliance 1 further comprises a guide system 12. At least one tray 7, 8, 9 is slidably mounted by this guide system 12. The guide system 12 allows a tray 7, 8, 9 to be guided out of and pushed into the receiving space 3 in the depth direction (z-direction) of the household refrigeration appliance 1.

[0048] In Fig. 2 The household refrigeration unit 1 is partially shown in a vertical sectional view. The receiving chamber 3 is shown here as an example in this vertical sectional view. The section plane is defined by the vertical direction (y-direction) of the household refrigeration unit 1 and the horizontal direction. The guide system 12 is also shown here. It has a guide unit 13, 14, and 15 for each tray 7. The guide unit 13 has a guide rail 16. The guide rail 16 is arranged on a side wall 17 that defines the receiving chamber 3. The guide rail 16 is partially designed as a hollow profile. It has a hollow profile top 18. In particular, it also has a hollow profile bottom 19. Several stiffening struts 20 can be arranged in the hollow profile, of which only some are labeled with reference numerals for clarity.

[0049] On this guide rail 16, in particular the hollow profile slab 18, the shell 7 can be coupled to a shell-side guide rail 21. This shell-side guide rail 21 can rest on this external guide rail 16 for movement in the depth direction. This shell-side guide rail 21 is arranged here on a side wall 22 of the shell 7. It can, in particular, be formed integrally with it. In particular, it can, for example, be formed as an injection-molded component.

[0050] Accordingly, a guide rail 16 and a shell-side guide rail 21 are also designed for the further shell 8. In particular, shells 7 and 8 are identical in design. Likewise, the guide units 13 and 14 are preferably identical in design. The aforementioned explanations and also the following explanations, in particular regarding the guide rail 16 and the shell 7 as well as specific anti-tilt and / or extension-stop devices, then apply analogously to the shell 8 and the guide unit 14.

[0051] In contrast, in Fig. 2 Another embodiment of a guide unit 15 is also shown, which is designed differently from the guide units 13 and 14. A guide rail 23 is shown. This is geometrically different from the guide rails 16. The guide rail 23 can also be formed as a hollow profile. However, it can also be designed in other ways.

[0052] In the exemplary embodiment, the guide rail 23 is provided with a local projection 24 at a forward end 23a (viewed in the depth direction). This local projection 24 is preferably a bearing point on which the shell 9 shown here is tiltably mounted. As can be seen here, a shell-side guide rail 25 with a base 26 rests on this bearing point 24 from above. In the illustrated embodiment, all shells 7, 8, 9 are shown in an extended position. This means that they are extended to their maximum extent forward in the depth direction, but are still coupled to the guide units 13, 14, and 15.

[0053] In these extended positions, a tilt protection and / or extension stop device 27 also takes effect. For the embodiment of the tray 9 and the guide unit 15, a tilt protection and / or extension stop device 28 is also provided in one embodiment.

[0054] The tilt protection and / or extension stop devices 27 and 28 enable the trays 7, 8 and 9 to extend beyond their Fig. 2 The maximum extension position shown cannot be extended further forward. In addition, or alternatively, these anti-tilt and / or extension stop devices 27 and 28 also limit downward tilting of the trays 7, 8, 9. Only slightly tilted positions of the extended trays 7 to 9 are shown here. These positions are held and defined by the anti-tilt and / or extension stop devices 27 and 28.

[0055] The tilt protection and / or extension stop device 27 has a shell-side stop element 29. In the illustrated embodiment, this is designed as the rear end of the guide rail 21. Viewed vertically, this stop element 29 is extended upwards relative to the remaining, forward-adjoining section 30 of the guide rail 21. The shell-side stop element 29 is specifically designed as a hollow profile. The hollow profile is open laterally in the width direction (x-direction). In one embodiment, the hollow profile preferably has at least one stiffening strut 31. Furthermore, the stop element 29 has a stop wall 32. The stop wall 32 is inclined.

[0056] It is provided that the shell 7 has at least one stabilizing element 33. The stabilizing element 33 is connected to the shell-side stop element 29, in particular directly connected. It is formed integrally with it. The stabilizing element 33 is thus connected to the stop element 29 at a first, here in particular lower, end 33a. At a further second, here upper, end 33b, this stabilizing element 33 is connected to a shell part 34 of the shell 7, in particular directly connected. It is in particular manufactured integrally with it. In one embodiment, the shell part 34 can form or be a plate web. The plate web can be formed at an upper end or an upper edge of the shell 7. However, the plate web can also be offset downwards in the vertical direction relative to an upper edge of the shell 7.The stabilizing element 33 is preferably formed here as a plate-like strip. As shown in . Fig. 2 In the illustrated embodiment, the stop element 29 is suspended by this stabilizing element 33 on the plate web arranged above it in the vertical direction.

[0057] Furthermore, it can also be seen that the stop element 29 extends, at least in some areas in the depth direction, backwards beyond a bearing volume 35 of the shell 7. Therefore, this stop element 29 projects backwards beyond this bearing volume 35.

[0058] The tilt protection and / or extension stop device 27 also includes a counter-stop element 36. The counter-stop element 36, which is external to the shell, is preferably formed on the guide unit 13. In particular, it is formed integrally with this guide unit 13. The stop element 36 is preferably arranged on a support arm 37 projecting upwards from the guide rail 16. It is positioned vertically above the guide rail 16. A guide track 38, along which the shell 7 is guided in the depth direction through the guide unit 13, is limited at this local point by the counter-stop element 36.

[0059] In one embodiment, the counter-stop element 36 has an inclined rear wall 39. This inclined rear wall 39 is arranged at an angle. In particular, it has the same inclination as the stop wall 32. In the extended position, as described in Fig. 2 As shown, the stop wall 32 and the rear wall 39 lie flush against each other. This also limits the tilting position of the tray 7. As can be seen, the counter stop element 36 and the stop element 29 overlap vertically, thus also forming the extension stop. Therefore, the stop element 29 cannot be pushed past the counter stop element 39 in the depth direction, thus preventing or stopping any unwanted complete extension of the tray 7.

[0060] As shown in the embodiments of the guide rails 21, the remaining section 30 is uniform in height along its entire length.

[0061] In the exemplary embodiment of the tray 9, a corresponding remaining section 40 at the transition to the stop element 29 is formed with a thinning point 41. Furthermore, this remaining section 40 is not straight along its entire length, but is angled upwards in the front area. This allows the tray 9, when fully inserted, to slide over the bearing point 24 and, in the inserted end position, to lower completely onto the guide rail 23.

[0062] In the exemplary embodiment of the shell 9, it can be seen that the stop element 29, viewed in the depth direction, is arranged completely behind the bearing volume 35 of the shell 9. It is thus arranged to project completely rearward beyond this bearing volume 35.

[0063] In Fig. 3 Figure 7 shows an embodiment of the shell 7 in a perspective view from a rear oblique angle. As can be seen here, a stop element 29 is directly formed on each of the opposite side walls 7a and 7b. The stop elements 29 project laterally in the width direction. They are arranged to cantilever freely to the side. The respective stabilizing elements 33 are also visible. As shown in Fig. 3 As shown, a stabilizing element 33 does not extend in the lateral direction over the entire length of the stop element 29 measured in this lateral direction. In the exemplary embodiment, a stabilizing element 33 extends in this lateral direction over only a portion of the length of a stop element 29. In particular, a stabilizing element 33 extends from the outside of a side wall 7a, 7b only partially over the length of a stop element 29. As a result, an end of a stop element 29 facing away from the respective side wall 7a, 7b in the lateral direction is exposed. This allows direct coupling with the respective counter-stop element 36 without the stabilizing element 33 being in the way.
