Food storage container with a climate control device with specific adjustment between a tray and a top, as well as a household refrigeration appliance

Description

[0001] One aspect of the invention relates to a food storage container for a household refrigeration appliance, comprising a tray for holding the food and an air conditioning device that allows air to be exchanged between the environment and the interior of the food storage container. The food storage container has a wall attachment that is separate from the tray and can be placed on the tray from above. Another aspect relates to a household refrigeration appliance.

[0002] Food storage containers for household refrigeration appliances are widely available. These can typically be placed in a food storage compartment of the household refrigeration appliance. This storage compartment is defined by the walls of an inner container of the household refrigeration appliance. The storage compartment can be a refrigerator compartment or a freezer compartment.

[0003] Furthermore, known designs of food containers provide for such a ventilation device or air conditioning device to be arranged in a lid that is designed and arranged separately from the tray. This results in restricted movement or possibly cramped situations for operating the air conditioning device. To operate such devices, relatively complex mechanical assemblies are required on a lid or cover in order to make the settings using an operating element. Such an operating element is coupled to a variety of necessary mechanical components of the assembly in order to convert, for example, a sliding movement or a rotational movement of the operating element into a movement of the lid.

[0004] EP 3 343 156 A1 discloses a cover frame with hooks on its rear side, wherein a cover has projections that engage with these hooks. A knob is arranged on the front of the cover frame, which extends through an opening in the cover frame and is coupled to an adjustment member and an adjustment band. The adjustment member and the adjustment band are mounted in a groove in the cover, so that the cover is displaced by means of the adjustment member and the adjustment band when the knob is actuated.

[0005] CN 200 952 864 Y discloses a frame having eyelets at its rear end. Operating slides are provided at the front end of the frame, by means of which a cover can be adjusted. The operating slides are operated by buttons accessible through openings on the front of the frame. The operating slides are essentially L-shaped.

[0006] It is an object of the present invention to provide a food storage container in which the operation of an air conditioning device is improved.

[0007] This object is achieved by a food storage container and a household refrigeration appliance according to the independent claims.

[0008] One aspect of the invention relates to a food storage container for a household refrigeration appliance. The food storage container has a tray for holding the food. The food storage container also has an air conditioning device. This device enables air to be exchanged between the environment and the interior of the food storage container. The food storage container, in particular, has an attachment separate from the tray. This attachment is, in particular, a wall attachment that can be placed on the tray from above. The wall attachment can be used to form a raised wall, at least in partial areas of the tray.

[0009] This air conditioning device is intended to carry out an air exchange between the environment and the interior of the food receptacle in a first operating state of the air conditioning device. The air conditioning device is therefore a physical component that has, in particular, at least two different operating states. The operating states can also be referred to as setting states. In this first operating state, an air exchange between the environment and the interior of the tray of the food receptacle is intended to be possible. In a second operating state of the air conditioning device, it is provided, in particular, that such an air exchange is at least reduced, at least in the region of the air conditioning device, compared to the first operating state.In particular, in this second operating state, the exchange of air in the area of the air conditioning device is prevented or substantially prevented.

[0010] It is provided that the air conditioning device has a lifting device. With this, the wall attachment is arranged so as to be movable relative to the tray in the vertical direction of the food storage container, such that in a ventilation position of the air conditioning device a ventilation gap is formed between the tray and the wall attachment. The ventilation position is the position in which the air conditioning device has the first operating state. Thus, such a food storage container makes it possible to enable individual air conditioning conditions between two specific components, namely the tray and the wall attachment. In particular, the wall attachment is placed directly onto the tray from above. In the ventilation position, in this context, a spacing at least in some areas and thus a corresponding ventilation gap is formed between these two components by the lifting device.This ventilation gap allows air to be exchanged between the environment and the interior of the food storage container. In the second operating state of the air conditioning device, this ventilation gap is closed. This means that the wall attachment sits directly on the tray. A food storage container of this type enables an improved air conditioning concept in this regard. A height-adjustable spacing can be created between the wall attachment and the tray at a very specific interface, particularly on the vertical walls of the food storage container, as required, or this can be left out. This also allows targeted ventilation to be provided as needed via such an entire side wall of the food storage container. Depending on the situation, the interior can therefore be ventilated via such a laterally open ventilation gap.This also makes it possible for other components of the food storage container to remain in the same position to accommodate such ventilation. This has the advantage of eliminating the need to reposition other components of the food storage container.

[0011] Particularly if the food container also has a lid, the lid can remain virtually unchanged in both operating states of the air conditioning device. This is because it is then no longer necessary for the lid to be repositioned relative to the tray to enable this type of air conditioning of the interior. It is also possible for the wall attachment to be part of a lid with a roof wall. The lid is then tub-shaped. An additional cover can then be provided, relative to which the lid can move, thus defining the operating states of the air conditioning device.

[0012] In one embodiment, the lifting device is designed for manual operation by a user. This also enables a simple concept. A component-saving design is achieved. Therefore, no additional motors or the like are provided in this context that would operate the lifting device. This also ensures that the volume of the interior of the shell is not compromised, allowing it to be designed relatively large.

[0013] A wall extension is intended for raising the height of one wall of a food storage container. It is particularly designed for raising a side wall and / or a rear wall of the tray. It can therefore also be referred to as a wall extension.

[0014] According to the invention, the lifting device is arranged directly on the wall attachment. This allows a highly functional mechanical operating principle to be achieved. This is because complicated and mechanical coupling chains, which would be required if the lifting device were arranged remotely from the wall attachment, can be eliminated. This significantly reduces or even eliminates both tolerance chains and malfunctions. This also eliminates the need for complex mechanical assemblies with separate operating elements on the lid or the cover itself. Such elements are therefore not present in the food storage container. Rotating elements or similar operating elements are then no longer required. The invention also eliminates the need for a wide variety of components that convert the movement of the operating element into movement of the lid.

[0015] The lifting device, including all its components, is mounted directly on the wall attachment itself. This particularly supports the aforementioned advantages.

[0016] According to the invention, the lifting device has at least one elongated slide. In one embodiment, this slide is arranged on the wall attachment so that it can be moved relative to the wall attachment in the depth direction of the food storage container and / or in the height direction of the food storage container. These very specific directions of movement of the elongated slide also enable a very simple actuation concept. Very simple movements of the slide are thereby achieved. This also reduces the complexity of the arrangement. Furthermore, an elongated slide can be securely grasped and actuated, especially when operated manually by a user. This also enables user-friendly operation of the lifting device.

[0017] According to the invention, the wall attachment has at least one side part. This side part extends in the depth direction of the food receptacle. In particular, it is arranged flatly in a plane spanned by the depth direction and the height direction of the food receptacle. The side part has a side wall. The side part also has a bottom wall that protrudes from the side wall at an angle, in particular 90°. In particular, the bottom wall is horizontally oriented. The slider is arranged so as to rest on the bottom wall, at least in part. It is adjustable relative to the bottom wall. This enables an advantageous concept, at least in terms of position. This is because a niche formed by this L-shaped geometry of the side part can serve to accommodate this slider.This creates an overlapping arrangement between the side panel and the slider, at least in the lateral extension of the base wall. This creates a space-saving concept. It also allows this base wall to cover or protect the slider arrangement from below. The base wall can extend inward from the side panel. In this case, the slider is arranged inside the food receptacle. In another embodiment, the base wall is oriented outwardly, starting from the side wall. This allows the slider to be arranged outside the food receptacle. It is then accessible from the outside.

[0018] In one embodiment, the bottom wall has an elastically springy bottom wall section, viewed in the vertical direction of the food receptacle. In particular, this bottom wall section sits on the tray. In particular, it rests directly on it. This is another very advantageous embodiment because it allows for a simple mechanical operating principle to be implemented to transfer the movement of the slider into a movement of the bottom wall section, thereby effecting the relative position change between the wall attachment and the tray. Very short mechanical operating chains are thus achieved. A low complexity of the concept is enabled.

[0019] In one embodiment, the base wall section is coupled to the slide. Depending on a first actuating position of the slide, the base wall section is pressed downwards by this slide, viewed in the vertical direction. Due to the base wall section resting on the shell, the wall attachment is then raised upwards relative to the shell, viewed in the vertical direction, and the ventilation gap is formed. Due to the few components, which are mechanically coupled to one another in a simple yet robust, highly functional operating principle, the air conditioning device can be very easily adjusted between at least the two aforementioned operating states. Therefore, the air conditioning device is also permanently highly functional in this regard.Precisely due to this elastically springy design of the base wall section, it can be moved reversibly and independently between the deflected position and the home position. This can be achieved easily and precisely thanks to the direct action of the slider on this base wall section.

[0020] In one embodiment, the base wall section is coupled to the slider, so that depending on a second actuation position of the slider, the base wall section is not actuated by the slider. Because the base wall section rests on the shell, the wall attachment is then not raised upwards relative to the shell and no ventilation gap is formed. Thus, the interface between the shell and the wall attachment is closed in this state. In particular, the wall attachment then sits directly on the shell. This is then the second operating state of the air conditioning device. Due to the weight of the wall attachment, this second operating state can also be safely maintained. An undesirable occurrence of a spacing and thus an undesirable occurrence of the ventilation gap is thus avoided.

[0021] In one embodiment, a guide web is formed on one side of the side wall of the side part. This side can be the inner side, which faces the interior of the food receptacle. This guide web engages in a guide groove. The guide groove is formed on the slide. The slide is thus displaceable by this guide device. In particular, it is mounted on the side part so that it can be moved linearly in the depth direction of the food receptacle. This enables a very simple movement scenario for the slide. On the other hand, this direct mechanical coupling of the slide to the side part, in particular the side wall of the side part, also enables a space-saving and component-saving concept. Complex and extensive coupling devices are then not provided here. In one embodiment, the web can have a sliding block on its upper side.This sliding block can engage with a guide slot formed as a guide groove in the slide. In particular, this guide slot, formed by the guide groove, can be located on an upper side or in an upper wall of the slide. As a result, the sliding block essentially engages with this guide slot, viewed vertically.

[0022] In one embodiment, a guide web is formed on one side of the side wall of the side part. This side can be the outer side, facing away from the interior of the food receptacle.

[0023] In one embodiment, the slider has an actuator. In one embodiment, the slider has a hollow area on its underside. The downwardly freely projecting actuator of the slider can be arranged in this hollow area. This actuator is designed for mechanical coupling, in particular for direct coupling, to the elastically springy base wall section. Depending on the displacement position of the slider relative to the wall attachment, this actuator acts on a base wall section of the base wall, in particular on an elastically deformable base wall section of the base wall, to deform it. In particular, the relevant deformation is generated as intended and in a defined manner in the vertical direction of the food receptacle. A defined element is thus arranged in this hollow space as the actuator, which acts on this base wall section very precisely and depending on the displacement position.This also ensures that this elastic deformation of the base wall section occurs continuously rather than abruptly, allowing the corresponding bending of the base wall section from its initial position to be very controlled and even. This also ensures that the wall attachment is lifted from the shell to set the initial operating state of the air conditioning device not abruptly, but rather through a very continuous and even process. This also prevents unwanted abrupt force peaks on the components.

[0024] Such a slider can be designed in a bar-like manner. In one embodiment, two separate sliders are provided. These are arranged in pairs on opposite sides of the wall attachment.

[0025] In one embodiment, the wall attachment can have these two side parts. In one embodiment, it can also have a rear part. The wall attachment can be formed in one piece. In the above-mentioned configuration, it can also be U-shaped. Particularly when the side walls of the shell and a rear wall of the shell are lower in height than a front wall of the shell, a corresponding elevation of these side walls and / or the rear wall of the shell can be achieved by means of such a wall attachment.

[0026] The side parts of the wall attachment can have the same or essentially the same height over their entire length, as viewed in the depth direction of the food storage container. It is also possible for these side parts to vary in height. In this context, the height of the side parts of the wall attachment can be continuously decreased. In particular, they can be continuously tapered from a rear end to a front end.

[0027] In one embodiment, the slider, viewed in the width direction, protrudes no more than 10 centimeters, or at most, beyond the base wall of a side section of the wall attachment. This also further supports the compact and highly functional design. It also enables particularly efficient action on the elastically springy base wall section.

[0028] In one embodiment, the lifting device has at least one tilting beam. The tilting beam is tiltable about a tilting axis oriented in the width direction of the food receptacle. The tilting beam is mechanically coupled to a separate side part of the wall attachment. The tilting beam is adjustable relative to the side parts of the wall attachment in at least two different, discrete tilting positions. In a first tilting position, the side part and the tilting beam are offset in the vertical direction of the food receptacle in such a way that the ventilation gap is formed. In this first tilting position, the first operating state of the air conditioning device is therefore set. In a second tilting position of the tilting beam, which is different from the first tilting position, the side part and the tilting beam are arranged relative to one another in such a way that the ventilation gap is closed. This is then the second operating state of the air conditioning device.A direct mechanical coupling is therefore formed between the at least one tilting beam and a side part of the wall attachment, such that these two components can move relative to one another and the at least two discrete and different tilt positions can be adjusted relative to one another. Since the tilting beam is positioned differently to the side part in these two tilt positions, the different height positions of the components relative to one another also arise. This in turn results in a corresponding influence on the height of the side part and / or the tilting beam in relation to the shell. These different tilt positions therefore allow the tilting beam and / or the side part to be positioned in a different position relative to the shell in the height direction, at least in some areas.This results in the air conditioning device being open on the one hand and closed on the other. In one embodiment, the tilting beam can also be part of the wall attachment along with the side panel. If the wall attachment has two side panels, two tilting beams can also be formed, each coupled to one of the two side panels.

[0029] In one embodiment, the at least one tilting beam is arranged parallel to a side part of the wall attachment. Thus, the tilting beam extends with its longitudinal axis in the depth direction and thus also preferably parallel to the longitudinal axis of the side part. The two components are thus arranged parallel to each other in the depth direction over at least 50 percent, in particular at least 60 percent, in particular at least 70 percent. This also realizes a correspondingly highly functional tilting principle. This is because the tilting axis, or the related horizontal axis about which the tilting beam can be tilted, also enables a correspondingly advantageous lever principle. In particular, this tilting axis is formed at a rear end of the tilting beam, viewed in the depth direction.Particularly when the tilting bar extends to the front end of the side section of the wall attachment or essentially to the front end of the side section, the tilting bar can be easily tilted by actuating the front end. In particular, the tilting bar can have a handle at a front end, by which a user can grasp the tilting bar as intended for tilting. The operating principle explained above, in particular with the maximum offset position between this handle and the tilting axis, allows for the implementation of an advantageous lever principle. This also enables the tilting to be very smooth and user-friendly.In particular, if the wall attachment has several side parts, in particular two opposite side parts, and a rear part and is in particular U-shaped in this regard, a simple raising and lowering of the side parts and / or the at least one tilting beam can then also be carried out via this tilting mechanism.

[0030] In one embodiment, the tilting bar is coupled to the side panel with an at least two-stage snap connection, in particular coupled directly thereto. In a first, discrete snap position of the snap connection, a first height offset is set between the tilting bar and the side panel, thereby forming the ventilation gap. In this first snap position, the air conditioning device is thus set in the first operating state. This specific snap connection allows the at least two different discrete operating states of the air conditioning device to be set very precisely. Last but not least, such a design also easily achieves a simple haptic perception of the different discrete operating states for a user.Last but not least, such a design of a snap connection allows the currently set operating state and thus the set snap position to be maintained independently, thus locking it to a certain extent. Adjustment from one snap position to another is then only possible through the user's manual intervention. Therefore, the snap connection is also designed to be self-locking in each of its snap positions.

[0031] In both of the above-mentioned embodiments, a redundant design of the sliders on the one hand and the tilting beams on the other can be provided. This also allows for synchronous adjustment via both sliders and both tilting beams. This enables a very uniform raising and lowering of the wall attachment. This can be better prevented from jamming or spreading.

[0032] In one embodiment, a tilting bar can be a component of a tilting bracket. The tilting bracket can have two tilting bars. These can in particular be connected to a connecting bar. This connecting bar is connected to the tilting bars in particular at the rear ends. In one embodiment, the tilting bracket can therefore also be U-shaped. In one embodiment, it is therefore adapted to an advantageous design of the wall attachment. In one advantageous embodiment, this can also be U-shaped. This makes the entire construction mechanically more stable and even stiffer with regard to the relative settings via the tilt positions. This also enables the corresponding adjustment to be very precise and permanently highly functional. In one embodiment, the wall attachment can be arranged on the lid of the food storage container. If necessary, it can be suspended from it.In this context, it can also be arranged on the cover so that it can be adjusted in height relative to the cover. In particular, it is intended that the cover remains unchanged in its position when the wall attachment is adjusted in height relative to the shell. Regarding the air conditioning device, only the design of the ventilation gap between the wall attachment and the shell is relevant here. Possible other gaps or spaces, which are formed, for example, between a roof wall of a cover and the wall attachment, are not to be considered part of the air conditioning device described here.

[0033] Furthermore, this concept is also advantageous in that the sliders, on the one hand, and the tilting bars, on the other, are located externally to the tray. Since the tray can move relative to the wall attachment in the depth direction of the food storage container, the wall attachment can be adjusted independently of the tray's position. This makes it easy to change the position of the sliders or tilting bars, even when the tray is pulled out, for example. This also makes for a user-friendly adjustment.

[0034] In this context, the food storage container can also be used as a freshness container. Different storage conditions can be set compared to the rest of the storage space. In particular, different climate control is possible here. Different temperatures and / or humidity levels can be set.

[0035] A further aspect of the invention relates to a household refrigeration appliance. This has at least one food storage container according to the above-mentioned aspect or an advantageous embodiment thereof. The household refrigeration appliance can be a refrigerator or a freezer or a refrigerator-freezer combination appliance. The household refrigeration appliance can have a housing. This housing has an outer housing. A separate inner container is accommodated in the outer housing. The inner container, with its walls, delimits at least one receiving space of the household refrigeration appliance. The receiving space can be a refrigerator compartment or a freezer compartment. The food storage container is a separate component that can be arranged in this receiving space. The food storage container can also be removed from this receiving space as a whole. It is also possible that, in addition to or instead of this, only the tray of the food storage container can be removed.This can also be pulled out and pushed in along the depth of the household refrigerator.

[0036] The terms "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" indicate the positions and orientations given during normal use and proper arrangement of the container or device.

[0037] Further features of the invention emerge from the claims, the figures and the description of the figures.

[0038] Embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: Fig. 1 is a perspective view of an embodiment of a household refrigeration appliance according to the invention; Fig. 2 is a perspective view of an embodiment of a food receptacle according to the invention; Fig. 3 is a perspective view of subcomponents of the food receptacle according to Fig. 2 ; Fig. 4 a side view of a side part of a wall attachment of the food receptacle according to Fig. 2 ; Fig. 5 a side view according to Fig. 4 with a slider arranged thereon in a first sliding position; Fig. 6 the representation according to Fig. 5 , in which the slider is in a Fig. 5 different displacement position; Fig. 7 a perspective view of a further embodiment of a food receptacle according to the invention; Fig. 8 a sectional view through a partial area of the food receptacle according to Fig. 7 in a first tilting position of a tilting beam; Fig. 9 the representation according to Fig. 8 , where Fig. 9 the tilting beam in a Fig. 8 different tilting positions; Fig. 10 a perspective enlarged view of the design in Fig. 8 ; and Fig. 11 an enlarged view of the design in Fig. 9 .

[0039] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0040] In Fig. 1 In an exemplary representation, a household refrigeration appliance 1 is shown, which is designed as a fridge-freezer combination appliance. The household refrigeration appliance 1 has a body 2 with an inner container 3. The inner container 3 has, among other things, two opposite vertical side walls 3a and 3b. The inner container 3 delimits with its walls a first interior space or receiving space 4, which is a cooling compartment, and a second interior space or receiving space 5, which is arranged below it and separated therefrom and is a freezer compartment. The receiving space 4 is generally used for frost-free cooling of refrigerated goods, preferably at temperatures between +4 °C and +8 °C. However, the receiving space 4 can also be designed as a zero-degree compartment, in particular for keeping fruit or vegetables fresh. The receiving space 4 is accessible when the door 6, which closes the front of the receiving space 4, is open.

[0041] The additional storage compartment 5 is generally used for deep-freezing frozen goods, for example, at -18 °C. The storage compartment 5 is accessible when the freezer compartment door 7 is open.

[0042] A refrigerated goods container or fresh-keeping container is stored in an extendable manner in the upper receiving space 4. The fresh-keeping container represents a food receptacle 8. The food receptacle 8 has a drawer or tray 10. In one exemplary embodiment, the food receptacle 8 also has a lid 9. This is separate from the tray 10. The lid 9 can only be provided for closing the tray 10 from above. It can then be placed directly onto the tray 10. In one exemplary embodiment, it can also be provided that the lid 9 is also designed as a shelf or partition. It is then mounted in particular directly on the side walls 3a and 3b. In one exemplary embodiment, it is then not resting directly on the tray 10, but in particular is arranged slightly offset upwards therefrom.

[0043] It can also be provided, as shown, that a separate cover 11 is arranged in addition to the cover 9, for example in the form of a partition, such as a glass shelf. This is arranged directly above the cover 9 and slightly spaced from the cover 9.

[0044] Another or different food container 8' may also be provided.

[0045] At least by the cover 11, the food receptacle 8 is separated from the remaining partial volume of the receiving space 4.

[0046] The food receptacle 8 can be removed from the receiving space 4 in a non-destructive manner. Even when inserted into the receiving space 4, the tray 10 can be pushed back and forth in the depth direction and thus in the z-direction while still stored in the receiving space 4 in order to access the interior of the tray 10. The same can also be provided for the food receptacle 8'. This can also be designed with a tray 10 and in particular also with a lid 9. A cover 11 can then also be arranged directly above the lid 9. This is then arranged, for example, directly below the tray 10 of the food receptacle 8. The tray 10 of the food receptacle 8 can then be placed on this cover 11 of the food receptacle 8'.

[0047] In one embodiment, the food receptacle 8' can be longer in the depth direction than the components arranged directly above it. It can therefore be designed to be longer in this depth direction toward the front than the food receptacle 8 arranged above it, for example. In this case, the food receptacle 8 can also be just a simple bowl. It can then also be designed differently and does not necessarily have to be a freshness container.

[0048] In principle, a food storage container 8, 8' can be intended for storing specific food items. In this context, different storage conditions can also be set in such a food storage container 8, 8' compared to the rest of the storage space 4.

[0049] In particular, storage conditions, such as individual temperature and / or humidity, can be adjusted inside the food storage container 8' or 8. This enables individual climate control.

[0050] In Fig. 2 is shown in a perspective view as an embodiment of the food receptacle 8'. The tray 10 has a front wall 12 and opposite side walls 13 and 14, a bottom wall 15 and a rear wall 16. The food receptacle 8' further has a wall attachment 17 as an example of an attachment as shown in Fig. 3 is shown in a partial illustration. The wall attachment 17 is a separate component from the shell 10. It is intended to be placed vertically from above onto the shell 10. This allows a corresponding wall elevation to be generated in specific areas of the shell 10. In particular, the exemplary embodiment provides for the side walls 13 and 14 and the rear wall 16 to be lower than the front wall 12. These height differences are compensated for, at least in some areas, by the separate wall attachment 17. In particular, the wall attachment 17 sits directly on the upper edges of the side walls 13 and 14 and / or the upper edge of the rear wall 16. In one exemplary embodiment, the wall attachment 17 can be arranged on the lid 9. For example, it can be attached to the lid 9 from below. In this context, it is possible for the wall attachment 17 to be arranged so as to be movable vertically relative to the lid.However, it can also be provided that the wall attachment 17 and the cover 9, which then forms a roof wall, are designed as a single cover. It can then also be formed as a single piece. This embodiment is particularly possible if the cover 11 is present. The cover 9 designed in this way can then be movably attached to this cover 11.

[0051] In the exemplary embodiment, the wall attachment 17 has a side part 18. In particular, it also has a further side part 19 at the opposite end ( Fig. 4 ). In one exemplary embodiment, the wall attachment 17 can have a rear part 20. This connects the two side parts 18 and 19. In particular, the wall attachment 17 is then U-shaped in such an embodiment. The wall attachment 17 can be formed in one piece. For example, it can be made of plastic. In one exemplary embodiment, the side parts 18 and 19 extend over at least 50 percent, in particular at least 60 percent, in particular at least 70 percent, in particular at least 80 percent of the depth-measured length of the side walls 13 and 14.

[0052] As in Fig. 3 As can be seen, the side part 18 has a side wall 21. A bottom wall 22 of the side part 18 adjoins this side wall 21 at the lower edge. In cross-section, the side part 18 is thus particularly L-shaped. The side part 19 can be designed accordingly. The food receptacle 8' has an air conditioning device 23. The air conditioning device 23 is intended to enable an air exchange between the interior of the food receptacle 8', in particular the tray 10, and the surroundings of the food receptacle 8', depending on the situation. The air conditioning device 23 has at least two specific operating states. In the first operating state, such an air exchange is enabled at a specific interface. This interface is formed in the area between the wall attachment 17 and the tray 10.In the second operating state, the air conditioning device 23 is closed. This means that air exchange at this interface between the wall attachment 17 and the shell 10 is at least lower than in the first operating state. In particular, air exchange at this interface is prevented or substantially prevented.

[0053] In one exemplary embodiment, the air conditioning device 23 comprises at least one lifting device 24. This lifting device 24 is intended to perform a position adjustment between the wall attachment 17 and the shell 10 in the vertical direction. In particular, it is intended to move or adjust the wall attachment 17 in this vertical direction relative to the shell 10.

[0054] As a result, the first operating state of the air conditioning device 23 can be set such that it has a ventilation position. In this ventilation position, a defined ventilation gap is formed between the shell 10 and the wall attachment 17. Therefore, air exchange can then occur precisely at this interface through the ventilation gap, as explained above. In the second operating position, this ventilation gap is absent or closed, and the wall attachment 17 sits directly on the shell 10, in particular the upper edges of the side walls 13 and 14 and the rear wall 16.

[0055] The lifting device 24 has in the embodiment according to Fig. 3 a slider 25. This is an elongated component. In particular, it is bar-shaped. The slider 25 is formed in one piece. It is arranged directly on the side part 18. It is arranged so as to be displaceable relative to the side part 18. In particular, this displacement possibility is linear. In particular, it is formed in the depth direction of the food receptacle 8'.

[0056] In the exemplary embodiment, another such slider 26 is arranged on the opposite side of the side part 19. This provides a redundant design. In particular, a symmetrical configuration can be provided here. This also allows for synchronous operation of both sliders 25 and 26. This enables a very smooth vertical movement of the wall attachment 17.

[0057] In particular, the sliders 25 and 26 are intended for manual operation by a user.

[0058] As in Fig. 3 As can also be seen, the slide 26, which is also shown here, has a top wall 27. A guide groove 28 is preferably formed in this top wall 27. This guide groove 28 is designed here, in particular, as a guide slot. Furthermore, it can also be seen that the slide 26 is hollow. In particular, it is designed to save weight and can therefore be moved more smoothly. In particular, it is open on the side facing the side part 19.

[0059] Furthermore, the slide 26 in the exemplary embodiment is designed with a downwardly open hollow region 29. This hollow region 29 faces the bottom wall of the side part 19. An actuator 30 of the slide 26 is arranged in this hollow region 29 or protrudes into this hollow region 29. In this respect, it extends downward. In this context, it is arranged cantilevered downwards in the vertical direction (y-direction).

[0060] The slider 25 is preferably designed in a similar way to the slider 26. As can be seen, in the exemplary embodiment, a guide web 32, in particular a horizontal one, is formed on an inner side 31a of the side wall 21 of the side part 19. In one exemplary embodiment, the guide web 32 has a sliding block 33. This is formed here on an upper side of the guide web 32 and extends upwards. This sliding block 33 engages from below in the guide groove 28 designed as a guide link. A slotted area 34 between the top wall 27 and an upper cover of the hollow area 29 also enables very precise guidance of the guide web 32 inside the slider 26. In particular, this also prevents the sliding block 33 from undesirably slipping out of the guide groove 28.

[0061] In Fig. 4 This side part 19 is shown. A bottom wall 35 of the side part 19 is also shown there. In a corresponding manner, the side part 18 is also provided with a corresponding guide web and a sliding block 36 ( Fig. 3 ). In this regard, the sliding block 36 is arranged in the corresponding guide groove 28 in the slide 25.

[0062] As furthermore in Fig. 4 As can also be seen, the bottom wall 35 has an elastic bottom wall section 37. This is designed as a freely projecting strip. In this respect, it is elastically springy in the vertical direction.

[0063] If the slider 26 is arranged in a correspondingly coupled manner on the side part 19, the actuator 30 can act on the elastic bottom wall section 37 depending on its linear displacement position in the depth direction.

[0064] In Fig. 4 the bottom wall section 37 is bent downwards. This is the case when the actuator 30 acts on it. For the sake of clarity, Fig. 4 This actuator 30 and the slider 26 are not shown in order to better recognize the structure of the bottom wall 35 and the bottom wall section 37.

[0065] In Fig. 3 a corresponding elastically springy bottom wall section 37' of the bottom wall 22 is shown.

[0066] In Fig. 5 a partial view of the food storage container 8' is shown. The side part 19 of the wall attachment 17 is shown here. The wall attachment 17 sits directly on the upper edges of the side walls 13 and 14 and / or optionally also the rear wall 16. The air conditioning device 23 is thus arranged in the second operating state. In this respect, it is closed. In this second operating state, the slide 26 is in a second actuating position. This can in particular be a rear position, viewed in the depth direction. In this position, the actuator 30 does not yet act on the base wall section 37 in such a way that this base wall section 37 would be pushed downwards from the basic position. Rather, it can be seen here that the base wall section 37 is arranged in the basic position and, in this context, is oriented in particular flush with the remaining area of the base wall 35.A ventilation gap between the wall attachment 17 and the side wall 14 is therefore not formed.

[0067] Now starting from the position in Fig. 5 If the air conditioning device 23 is actuated, this can be done by manually adjusting the slide 26. For this purpose, the slide 26 is directly grasped by a user and displaced backwards in the depth direction, as shown by the arrow P1, relative to the side part 19. As a result, the actuator 30 acts on the base wall section 37 and presses it downwards, as can be seen by the arrow P2. As a result, the wall attachment 17 is raised upwards in the height direction relative to the shell 10, in particular the side wall 14. This creates a ventilation gap 38 between an upper edge 14a of the side wall 14 and the base wall 35. The air conditioning device is then arranged in the first operating state.

[0068] If the slider 25 is also actuated accordingly, the same occurs at the interface between the side part 18 and the side wall 13. If the sliders 25 and 26 are adjusted simultaneously, the wall attachment 17 is raised synchronously relative to the shell 10 at all corresponding points.

[0069] The slider 26 remains in the Fig. 6 As a result, this first operating state of the air conditioning device 23 with the ventilation gap 38 then formed is automatically maintained. Only when a user manually pushes the sliders 25 and 26 forward again does the wall attachment 17 lower again and reach the state according to Fig. 5 .

[0070] In Fig. 7 In a further embodiment, a food receiving container 8' is shown.

[0071] In the Fig. 2 bis Fig. 4 In the embodiment explained, the cover 9 moves in particular in the vertical direction and in principle also in no other direction when an adjustment of the wall attachment 17 between the Fig. 5 und Fig. 6 shown positions.

[0072] In the embodiment in Fig. 7 The shell 10 is partially shown. It is also shown in the forwardly pulled out state in the depth direction. In this embodiment, in contrast to Fig. 2 bis Fig. 4 No design with sliders 25 and 26 is provided. Sliders 25 and 26 are separate parts and are intended for linear displacement in the depth direction.

[0073] In contrast, in the embodiment in Fig. 7 at least one tilting beam 39 is provided. In the exemplary embodiment shown here, the tilting beam 39 is also arranged in particular on the side part 18 of the wall attachment 17. Here, too, it is an elongated beam. In particular, it is mechanically arranged directly on the side part 18 and mechanically coupled thereto. In particular, a relative position adjustment option, namely tilting, between the tilting beam 39 and the side part 18 is possible here too. The tilting beam 39 extends with its longitudinal axis in the depth direction. It can be tilted upwards and downwards about a tilting axis A oriented in the width direction (x-direction). This tilting axis A is formed in particular at a rear end 39a of the tilting beam 39. If the tilting beam 39 is therefore lifted at a front end 39b, for example, a corresponding tilting about the tilting axis A occurs. For this purpose, a handle element 39c can be formed at the front end 39b.This can be, for example, a handle tab. In the exemplary embodiment, the food receptacle 8' has a further tilting bar 40. This is designed correspondingly to the tilting bar 39. In this context, it is arranged on the side part 19 of the wall attachment 17. In this respect, it extends parallel to the other tilting bar 39. In one exemplary embodiment, it can be provided that a tilting device 41 is formed. This has the two tilting bars 39 and 40. These can then be connected with a connecting bar 42. In particular, these tilting bars 39 and 40 are formed integrally with the connecting bar 42. The tilting device 41 is then U-shaped in this respect. It is then adapted in particular to the shape of the preferably U-shaped wall attachment 17.

[0074] The tilting bar 40 also preferably has a rear end 40a, a front end 40b, and a gripping element 40c. This configuration allows for simultaneous gripping of the gripping elements 39c and 40c, and for the tilting bars 39 and 40 to be tilted synchronously.

[0075] For this purpose, in one embodiment, the rear end 39a of the tilting beam 39 and the rear end 40a of the tilting beam 40 are uncoupled from the wall attachment 17. In particular, the tilting beam 39 and the tilting beam 40 rest on the shell 10 with their rear ends 39a and 40a.

[0076] In one embodiment, the tilting beam 39 is mechanically coupled directly to the side part 18 in the area of the front ends 39b and 40b. At this coupling point, these components are also movable relative to each other. In one embodiment, the tilting beam 40 is mechanically coupled to the side part 19 in the area of the front end 40b.

[0077] In Fig. 8 In a simplified sectional view of the food receptacle 8', an uncut side view of the tilting bar 40 is shown. Here, the air conditioning device 23 is shown in the second operating state. In this exemplary embodiment, in particular the tilting bar 40 sits directly on the upper edge or the upper edge of the side wall 14 of the tray 10. As can be seen here, the lid 9 is shaped accordingly, so that the tilting bar 40 is shown partially concealed by this lid 9. It can be provided that the side part 19 is arranged at a distance from the upper edge of the side wall 14. However, the side part 19 can also rest partially on the upper edge of the side wall 14 in the first operating state. In this case, in one exemplary embodiment, the tilting bar 19 can also be arranged at a distance from the upper edge of the side wall 14 in this second operating state.

[0078] If, starting from this second operating state of the air conditioning device 23, the tilting bar 40 is actuated, a relative adjustment takes place between the tilting bar 40 and the Fig. 8 und Fig. 9 The side part 19 of the wall attachment 17, which cannot be seen, is shown. In this context, as already explained above, the tilting beam 40 is raised at its front end 40b. By resting on the shell 10 at the rear end 40a, the tilting beam 40 tilts.

[0079] This creates, as shown in Fig. 9 also a ventilation gap 38 between the side wall 14 and the wall attachment 17. The first operating state of the air conditioning device 23 is then also set here. In particular, the ventilation gap 38 is only formed in the front area. In the rear area, the tilting beam 40 continues to rest directly on the upper edge of the side wall 14. Fig. 8 und Fig. 9 The explanations given for the tilting beam 40 also apply accordingly to the tilting beam 39.

[0080] In Fig. 10 is an enlarged view of the design according to Fig. 8 in the area of the front end 40b of the tilting beam 40. As can be seen, a snap connection 43 is formed between the tilting beam 40 and the side part 19. This is the coupling point between the tilting beam 40 and the side part 19. As a result, a first snap position and a different second snap position can be set at this front end 40b. In this regard, a relatively discrete height adjustment can thus be made between the tilting beam 40 and the side part 19. Fig. 10 the second snap position is shown.

[0081] In Fig. 11 is a corresponding representation as in Fig. 10 shown. In contrast to Fig. 10 However, a first snap position is shown here. In this position, the tilting bar 40 is raised upward at its front end 40b, forming the ventilation gap 38. In this context, the snap connection 43 can comprise snap elements and counter-snap elements. These are formed on the one hand on the tilting bar 40 and on the other hand on the side part 19. The respective tilt positions can then also be independently maintained by this snap connection 43.

[0082] In one exemplary embodiment, it can be provided that these tilting bars 39 and / or 40 lift the side parts 18 and / or 19 from the shell 14 or rest thereon. In this context, the side part 19 and / or the side part 18 can then be in direct contact with the side wall 14, in particular the upper edge 14a, when placed on it. In such an exemplary embodiment, the tilting bar 39 and / or the tilting bar 40 can then also be arranged at a distance from the shell, at least in some areas. In particular, only the upward tilting movement of the front ends 39b and 40b is then required in order to be able to switch from the second operating state to the first operating state of the air conditioning device 23.

[0083] However, in another exemplary embodiment, it is also possible for the tilting beams 39 and / or 40, in the basic configuration, to be the components that rest on top of the shell 10, particularly over their entire length, when the second operating state is set. Thus, in this exemplary embodiment, at least these tilting beams 39 and 40 are the components that close the ventilation gap 38 or, in principle, do not yet form it. In such an exemplary embodiment, the side parts 18 and 19 of the wall attachment 17 can then also be arranged at a distance from the side walls 13 and 14, particularly over their entire length.If a first operating state is then set in such an embodiment, a relative adjustment of the tilting bar 39 and / or the tilting bar 40 relative to the side parts 18, 19 takes place, in particular by the corresponding tilting movement at the front end 39b and 40b. As a result, as shown in the examples in . Fig. 8 bis 11 As explained, the fully supported state of the tilting beams 39 and 40 is removed, and the front ends 40b and 39b are lifted from the upper edges of the side walls 13 and 14. This then forms the ventilation gap 38. In this exemplary embodiment, it can then be provided that the side parts 18, 19 remain unchanged in their position in both operating states, and thus only a movement of these tilting beams 39 and / or 40 takes place in order to adjust the individual operating states of the air conditioning device 23.

[0084] In this exemplary embodiment, the tilting beam 39 and / or the tilting beam 40 can then also be part of the wall attachment 17. In this context, the side regions of the wall attachment 17 are then formed, on the one hand, by the side part 18 and the tilting beam 39, and, on the other hand, additionally or instead, by the side part 19 and the tilting beam 40. With such a multi-part construction of the side regions of the wall attachment 17, a corresponding relative position adjustment in the height direction is then also formed, viewed as a whole, between at least one component of such a side region of the wall attachment 17 relative to the shell 10.
