Description

One aspect of the invention relates to a food holding container. The food holding container has a container pan. This has a bottom wall and side walls. In addition, the food storage container has a front wall that is separate from the container trough. The front wall is movably arranged on the container pan. The food storage container also has a coupling device with which the front wall and the container pan are directly coupled to one another when the coupling device is in a coupled state and with which the closed end position of the front wall is held on the container pan. This coupling device has an actuatable coupling element which, in the coupled state, engages in a coupling receptacle of the coupling device. The coupling element has an outwardly oriented and exposed actuating surface for touching actuating with an actuating element. A further aspect of the invention relates to a domestic refrigeration appliance with at least one such food storage container.

Shell-shaped or trough-shaped refrigerated goods containers, which can also be referred to as food storage containers, are known in a variety of configurations. In this context, there are one-piece containers. In these configurations, the front wall is formed in one piece with the side walls and the bottom wall. In these embodiments, however, the cleanability of the volume accommodating space of this food accommodating container is difficult. In particular, transition areas between the walls mentioned and the bottom wall are more difficult to clean on the inside.

In this context in particular, exemplary embodiments of food storage containers are also known in which the front wall is designed to be movable relative to the rest of the body, namely the container trough. As a result, a front wall can be folded away from the container trough and thus also a front wall accessibility can easily be made possible. In particular, this improves the cleanability of the interior of this food storage container.

Such embodiments are from EP 2 591 297 B1 known. There is also a laterally accessible actuating element in the form of a push button. This can be pressed in the width direction of the local refrigerated goods container and thus the coupling device can be released. The closed state of the front wall can also be released in this way. This actuating element has an outward actuating surface which is flat.

In addition, from the EP 2 702 338 B1 a corresponding concept of a food receptacle is known. There the actuating element is a snap element. This has a snap plate. The snap plate forms a front end of this actuator. The snap plate has an outwardly oriented surface that is uneven. This actuating surface must be pressed in order to be able to move this actuating element in the width direction and thus be able to release the coupled state.

Due to the configuration of the actuating element there, however, target-oriented and user-friendly actuation is restricted. If necessary, an insufficient decoupling process can take place if the user contacts this actuating surface imprecisely with his finger.

It is the object of the present invention to create a food storage container and a household refrigeration appliance in which the actuation of an actuating element of such a coupling device is improved.

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

One aspect of the invention relates to a food holding container. This food storage container has a container pan. The container pan has a bottom wall and side walls. In addition, the food storage container has a front wall that is separate from the container trough. The front wall is on the container pan movably arranged. The food storage container also has a mechanical coupling device with which the front wall and the container pan can be mechanically coupled to one another. When the coupling device is in a coupled state, the front wall and the container pan are coupled directly to one another. In addition, the closed end position of the front wall on the container trough is also held by the coupling device. The coupling device has at least one actuable coupling element. In the coupled state, this engages in a coupling receptacle of the coupling device. The coupling element has an outwardly oriented and exposed actuating surface, which is intended to be designed to be actuated in contact with an actuating element. Through the targeted actuation of this actuation surface, the release of the coupling state is then made possible as intended. The coupling element has a delimiting web projecting in a raised manner from the actuating surface. An auxiliary positioning stop for the actuating element on the actuating surface is formed by this delimiting web or a raised edging. Such a configuration means that the coupling element is designed specifically in the actuation area. Since there is no longer just the actuation surface, but rather a raised boundary in this regard, a targeted positioning of the actuation element, in particular a finger of a user, on the actuation surface is made possible.

Since the delimiting web essentially predetermines the correct position for the finger on the actuating surface, a very user-friendly and correct actuation is also made possible. In particular, pressing on the actuation surface to release the coupling state is thus improved. This avoids placing the finger on the actuation surface, which may be highly asymmetrical, and the resultant jamming or spreading actuation of the coupling element to release the coupling state. This limiting web thus supports a very central positioning of the actuating element, in particular the finger, on the actuating surface. This also improves the action of force from the actuating element, in particular the finger, on the actuating surface. A more linear application of force is thereby achieved, so that the release process of the coupled state is made possible in a particularly advantageous manner. In addition, this limiting bar also allows that when pressing with the actuator on the Actuating surface slipping of this actuating element is prevented from the actuating surface improved.

At least a partial, in particular only partial, enclosure is thus also formed by this delimiting web. The finger placed on the actuation surface is thus also partially encompassed by this delimiting web and thereby held in its position on the actuation surface.

In one embodiment, the coupling element is a resilient pressing element. A particularly smooth actuation is thereby made possible. In particular, the automatic springing of the coupling element in the basic state is also achieved when the coupling element is not in the coupled state with the coupling receptacle. Furthermore, this resilient pressing element also means that when the coupling element and the coupling receptacle are coupled, the coupling element is initially moved out of the basic state and a certain resilient pretension is thereby brought about. If the position is then reached in which a sub-element, in particular an engagement piece, of the coupling element dips into the coupling receptacle, this also takes place automatically, since this resilient pretension causes this sub-element to snap into the coupling receptacle. The coupling state is then also maintained in an improved manner by this resilient pressing element. In particular, it can be provided in one exemplary embodiment that the coupling element is arranged in the coupling state in a manner that is still resiliently prestressed in the coupling receptacle. An undesired release of this coupling state is thus prevented in an improved manner.

In one embodiment, the operation surface is exposed to the side when viewed in the width direction of the food accommodating container. The coupling element can be moved in the width direction and, in particular, can be released in the coupled state. This positioning also enables easy accessibility for a user on the one hand and achieves a simple operating concept. On the other hand, this specific position means that the front wall is free of such a coupling element. Thus, in particular, it is also avoided that the coupling state would be released due to undesired impacts on the front side of the front wall of the food receiving container. This lateral positioning thus avoids an undesired release of the coupling state.

In addition, such a lateral arrangement is accompanied by a tidier condition and a calmer front-side appearance of the food accommodating container.

In one embodiment, the boundary ridge includes a vertical ridge portion. This means that this web part is oriented in the height direction of the food storage container. This is a particularly advantageous embodiment. This is because, on the one hand, a movement of the actuating element that occurs at least partially to the rear or in the depth direction of the food receptacle is limited. During such an approaching movement, the finger then hits this vertical web part. This advantageously prevents the actuating element from being positioned on the actuating surface so that it protrudes backwards or slips away backwards. A further advantage of this exemplary embodiment can be seen in the fact that a coupling wall of the coupling element, which is intended to reach over or reach behind a coupling receptacle, is raised by this vertical web part. The coupling state can thus be improved. Because an undesired loosening is thus avoided in an improved manner. Undesirable release of the coupling state is avoided in particular when, for example, relative movements between the coupling element and the coupling receptacle are also caused by the effects of force on the food receptacle, particularly in the width direction of the food receptacle. This is because the overlap between the coupling element and the coupling receptacle is increased by this vertical web part, precisely in the width direction of the food receptacle.

In one embodiment, the delimiting web has an upper, horizontal web part and/or a lower, horizontal web part. This is viewed in the height direction of the food accommodating container. In this context, the horizontal orientation is advantageously directed in the depth direction of the food receptacle. These further web parts can be used to limit the area upwards and/or downwards. This also allows the actuating surface to be touched by the actuating element at a precise location or this at a precise location Touching are advantageously supported. This avoids touching the actuating surface too far up or too far down.

In addition, these horizontal web parts make it possible to increase the rigidity of the coupling element in this area.

In one exemplary embodiment, it can be provided that a horizontal web part ends directly at the vertical web part. Thus, a coherent or uninterrupted delimitation bar is formed, which is not formed in a straight line. The advantages mentioned above with regard to the individual web parts are further improved here, since they are achieved in an operative connection with at least two spatial directions.

In one embodiment, the delimiting web is U-shaped. This achieves the advantages mentioned above with regard to the positioning accuracy of the actuating element on the actuating surface, the safety against slipping and also the mechanical rigidity of this partial area of the coupling element.

In one embodiment, the actuating surface and the delimiting web are formed in one piece with one another. This means that the number of components can be reduced and the position in the components mentioned in relation to one another is permanent.

In one embodiment, the entire coupling element is formed in one piece. It can be made of plastic, for example.

In one embodiment, the coupling element is formed in one piece with a side wall of the container pan. In particular, viewed in the depth direction of the food storage container, it is designed to be integrated in a front area of this side wall.

In one embodiment, the coupling receptacle is formed in the front wall, in particular formed in one piece with it. In one embodiment, the coupling receptacle can be a continuous hole in a wall area of the front wall.

The coupling receptacle extends over an area, in particular in a plane which is formed by the depth direction and the height direction of the food receptacle.

In one embodiment, the actuation surface is uneven. In this exemplary embodiment, the actuating surface has a partial actuating surface at the front in the depth direction of the food storage container. In this exemplary embodiment, the actuating surface has, in particular, a rear partial actuating surface directly adjoining the front partial actuating surface at the rear. These two partial actuating surfaces are arranged at an angle to one another.

This exemplary embodiment forms a certain depression or trough area on the coupling element in conjunction with the delimiting web. The even more targeted, position-stable contact of the actuating surface with the actuating element, in particular with a finger, is thereby made possible. This improves the auxiliary positioning stop.

In one embodiment, the delimiting web is arranged directly on this rear actuating surface. It is laterally raised and protrudes outwards from this rear actuating surface. In this way, in an advantageous manner, the actuating surface can be touched in a targeted and precise manner, in particular on the rear partial actuating surface. A particularly advantageous desired actuation process of this actuation element is thus made possible. In this regard, a quasi-optimal pressure point of the actuating element on the coupling element is made possible.

In this regard, a user no longer has to guess where such an optimal pressure point could be or no longer misses this optimal pressure point on the actuating surface. Just by looking, he can now see where the best position on the actuating surface is in order to be able to carry out the best actuating process in this regard for releasing the coupling state.

In one exemplary embodiment, the height of the delimiting web is formed in such a way that an upper edge of the delimiting web, in particular the entire upper edge, lies in one plane with the front partial actuating surface. The top edge of the boundary bar is the free edge of the delimitation web that faces away from the partial actuating surface. The delimiting web ends directly on this rear part of the actuating surface. It thus rises out of the plane of this rear partial actuating surface and thus extends laterally outwards in the width direction of the food receptacle, starting from the lower partial actuating surface. The height of the delimiting bar is dimensioned in the connection between the rear part of the actuating surface and the upper edge of the delimiting bar.

An advantageous geometry is achieved by the advantageous exemplary embodiment mentioned above. This is because the delimiting web does not protrude outwards beyond the actuating surface in its entirety. In this width direction in particular, it thus reaches the maximum position that is also reached by the front partial actuating surface. This configuration of the delimiting web also allows an edge-free transition of the upper edge to the front partial actuating surface to be achieved. An undesired bumping of the finger on such edges can thereby be avoided. This also enables a particularly user-friendly operating concept.

In one embodiment, the coupling element has an engagement piece. This engagement piece is intended to engage directly in the coupling receptacle. The coupling thus takes place in particular between the engagement piece and the coupling receptacle. This engaging piece has this operating surface. In particular, the entire actuating surface is formed on the engagement piece. The coupling element has a holding part ending at the engagement piece. With this holding part, the coupling element is arranged on the container trough or ends there. A wall step of the coupling element is formed between the holding part and the engagement piece. This wall step is intended for the purpose that, when the coupling element is in the coupled state with the coupling receptacle, it dips into this coupling receptacle. In the coupled state, this wall step therefore overlaps in one spatial direction, in particular in the width direction of the food receptacle, with the boundary edge of the coupling receptacle. The snapped state is thus reached.

In addition, in this advantageous exemplary embodiment, the possibility of increasing the wall step, as already explained above, is supported by the targeted arrangement of the vertical web part. This is because this step in the wall is enlarged. The immersion depth of the engagement piece in the coupling mount is also increased as a result. An undesired release of the coupling state is thus prevented in a particularly advantageous manner if, for example, a relative movement occurs in the width direction between the coupling element and the coupling receptacle in this coupling state due to the action of force. This can occur, for example, due to rolling storage goods in the food storage container, which then hit the walls of the container. Also, for example, pulling out or pushing the food storage container into a receiving space of a household refrigeration appliance can result in relative movements occurring between the front wall and the container pan and corresponding relative movements in the width direction between the coupling element and the coupling receptacle in the coupled state.

In particular, the wall step and the delimiting web, in particular the vertical web part, are arranged flush with one another on their outer sides.

In one exemplary embodiment, the delimiting web has a height such that the coupling element can be guided through between a wall of the front wall that has the coupling receptacle and the side wall of the container trough, in particular in the depth direction, as intended. This also enables simple coupling and decoupling.

From a general point of view, a food storage container is thus created that offers a wide variety of advantages. In particular, improved recognition of the particularly advantageous touch position of the actuating element on this actuating surface is achieved. In addition, it is precisely the delimiting bar that also enables haptic feedback for the user when he puts his finger on the actuating surface and also touches the delimiting bar in this regard. It is therefore also possible to give the user immediate feedback as to where the best possible pressure point is on the actuating surface.

In addition, the proposed solution also enables simple production. The manufacturing process is very simple, in particular if the front wall and the container pan are each made of plastic, in particular as injection-molded components. Existing injection molding tools practically do not have to be changed. Since the shape of the delimitation web is very simple, the relevant tools can also be easily adapted. The material requirement for this delimitation web is virtually negligible in this context.

The limiting web also means that when the user moves over the actuating surface from the front, he or she hits this limiting web with his finger as the actuating element, which means that he easily recognizes that the preferred actuating position on the actuating surface has been reached. In particular, the middle of the fingertip then lies directly on the best possible pressure point on the actuating surface.

A theoretically complete vertical wall step can be achieved in the advantageous exemplary embodiment, in which the wall step is formed between the engagement piece and the holding part, precisely when the coupling element is produced as an injection-molded part. Due to the necessary draft angles, this wall step is slightly inclined. Precisely in order to avoid the undesired release of the coupling state already explained above in such exemplary embodiments, the limiting web is a further advantage here. Because even with a wall step that is slightly inclined in this respect, the elevation of this wall with the limiting web prevents the coupling element from slipping out of the coupling receptacle laterally in the event of slight impact forces in the width direction. In this width direction, this tolerance of the relative movement between the coupling element and the coupling receptacle in the coupling state is increased by the limiting web.

A further advantage can be seen in the fact that the coupling between the coupling element and the coupling receptacle by the invention or an advantageous embodiment thereof is somewhat louder in terms of acoustic snapping. The snapped final state can thus be acoustically better perceived.

In particular, blind coupling and decoupling is more easily and better enabled for a user as a result of the proposed concept. This means that the user does not have to look explicitly at the coupling element and the coupling receptacle in order to be able to release the coupling state.

The indications “top”, “bottom”, “front”, “back”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction” etc. are the intended use and intended arrangement of the food receptacle or the guiding device or the device given positions and orientations.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

In 1 a domestic refrigerator 1 is shown in a schematic representation. The household refrigeration appliance 1 is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator or a freezer or a fridge-freezer combination appliance. The domestic refrigeration appliance 1 has a housing 2 . An inner container 3 is arranged in the housing 2 . The inner container 3 delimits a receiving space 4 for food with walls. The receiving space 4 can be a refrigerator compartment or a freezer compartment. Furthermore, the household refrigeration appliance 1 has a door 5 . This is movably arranged on the housing 2 . It is provided here for closing the receiving space 4 at the front.

A food receiving container 6 is arranged in the receiving space 4 , shown schematically. This can also be referred to as a refrigerated goods container.

In 2 an embodiment of a food storage container 6 is shown in a perspective view. The food storage container 6 has a container trough 7 . This container trough 7 has a bottom wall 8, a Rear wall 9 and opposite side walls 10 and 11 on. The container trough 7 forms a volume space 12 into which the stored goods can be placed. In one exemplary embodiment, the container pan 7 is designed in one piece. In particular, it is made of plastic.

The food receiving container 6 also has a front wall 13 . The front wall 13 is a separate component from the container pan 7 . It can be designed in one piece. It can be made of plastic, for example.

In 2 the front wall 13 is shown in its closed end position on the container trough 7 . In this connection, the front wall 13 forms a further vertical boundary wall, in particular a front boundary wall, of the volume space 12 . It can also be completely removed from the container trough 7 . This can be done non-destructively solvable.

The food receptacle 6 has a coupling device 14 . The front wall 13 is mechanically coupled directly to the container pan 7 with this mechanical coupling device 14 . In addition, the in 2 shown closed end position of the front wall 13 held on the container wall 7 by this coupling device 14.

In the depth direction (z-direction), a partial element of this coupling device 14 is formed in a front or front area of the side wall 11 . In particular, a corresponding partial element of the coupling device 14 is also present on the opposite side wall 10 in order to achieve a corresponding mechanical coupling with the front wall 13 on both sides.

As can be seen, this coupling device 14 is formed in the lower area between the side wall 11 and the front wall 13 and in the lower area between the side wall 10 and the front wall 13 viewed in the vertical direction (y-direction).

In one embodiment it is also provided that in the height direction in an upper area a mechanical coupling between the side walls 10 and 11 on the one hand and the front wall 13 on the other hand is formed. In this regard, only simple engagement elements 15 and 16 are formed on the side walls 10 and 11, which engage in corresponding receptacles in the front wall 13.

In 3 a perspective view of a lower corner area 17 of the side wall 11 is shown in an enlarged illustration. In this exemplary embodiment, a coupling element 18 of the coupling device 14 is designed in one piece with this side wall 11 . In addition, the coupling element 18 is also designed in one piece. The coupling element 18 is designed here as a resilient pressing element. It is designed to be resilient, particularly in the width direction (x-direction). The coupling element 18, which is part of the coupling device 14, has an actuating surface 19. The actuating surface 19 is intended to be able to be touched and actuated directly with an actuating element, for example a user's finger. In particular, a defined action of force is provided in this width direction in this regard. As a result, a coupling state between the coupling element 18 and a coupling receptacle 20 ( 4 ), which is also part of the coupling device 14, are solved.

In the exemplary embodiment, this actuating surface 19, which is exposed to the outside in the width direction, is uneven. It has a front actuating surface 19a in the depth direction (z-direction). The actuating surface 19 has a second, rear partial actuating surface 19b directly adjoining it directly to the rear in the depth direction. In one exemplary embodiment, these two partial actuating surfaces 19a and 19b are arranged at an angle to one another. In one exemplary embodiment, provision can be made for the partial actuating surface 19a to be flat. It can also be provided that the rear partial actuating surface 19b is flat. The two partial actuating surfaces 19a and 19b open out at a transition 19c to one another.

In one exemplary embodiment, the second, rear partial actuating surface 19b is inclined inwards towards the side wall 11, starting from the end which ends at the front partial actuating surface 19a. That is, the rear end of this rear operating surface 19b is positioned closer to the side wall 11 in the width direction than the front end facing the front operating surface 19a.

In addition, the coupling element 18 has a delimiting web 21 . The delimiting web 21 is raised and protrudes from the actuating surface 19 . In this regard, viewed in the width direction, it protrudes laterally outwards from this actuating surface 19 .

In the exemplary embodiment shown, the delimiting web 21 has a vertical web part 22 . This is thus oriented in the vertical direction of the food receptacle. In one exemplary embodiment, the delimiting web 21 has an upper, horizontal web part 23 . In one exemplary embodiment, the delimiting web 21 has a lower, horizontal web part 24 .

In one exemplary embodiment, the web parts 22, 23 and 24 are arranged without any interruption to one another and thus form a coherent delimiting web 21. In one exemplary embodiment, the delimiting web 21 has a U-shape.

As in the embodiment in 3 is shown, the limiting web 21 is formed on the rear part of the operating surface 19b and extends laterally raised from this rear part of the operating surface 19b to the outside.

In the exemplary embodiment, it is provided that the delimiting web 21 does not extend on the front delimiting partial surface 19a. It thus ends at the transition 19c. The delimiting web 21 is in particular an edge border of the rear partial actuating surface 19b.

Furthermore, it can be seen that this actuating surface 19 is formed with the limiting web 21 on an engagement piece 25 of the coupling element 18 . Viewed in the depth direction, this engagement piece 25 is the front end of the coupling element 18. In this respect, it is oriented so that it cantilevers forward. This engagement piece 25 is intended to engage directly in the coupling receptacle 20 . In one exemplary embodiment, the actuating surface 19 is formed exclusively and only on this engagement piece 25 . In particular, the limiting web 21 is formed exclusively and completely in one exemplary embodiment only on this engagement piece 25 .

In one exemplary embodiment, the coupling element 18 also has a holding part 26 . The holding part 26 ends at a wall area 27 of this side wall 11. In addition, this holding part 26 ends directly at the engagement piece 25. In this context, a wall step 29 is formed at a transition 28 between the engagement piece 25 and the holding part 26 . This means that a discrete offset is formed between the engaging piece 25 and the holding part 26 when viewed in the width direction. In this regard, the engagement piece 25 on this wall step 29 protrudes further outwards in the width direction than the holding part 26. This also means that only the engagement piece 25 dips into the coupling receptacle 20 in the width direction, as is shown in FIG 4 is shown. In one embodiment, the coupling receptacle 20 is as shown in 4 1, a through hole into which the engaging piece 25 snaps and engages outward as viewed in the width direction. This engagement piece 25 is thus arranged in an overlapping manner on this coupling receptacle 20 in the width direction. In this regard, this rear wall step 29 can in particular be in mechanical contact with an in 4 Be shown boundary wall 30, which limits the hole area of the coupling receptacle 20 to the rear. This wall step 29 is arranged so that it overlaps this boundary wall 30 or the relevant boundary edge in the width direction.

As in 3 As shown in the embodiment, the restricting ridge 21, particularly the vertical ridge portion 22, is formed at the rear end of the engaging piece 25. As shown in FIG. The vertical web part 22 is designed on the outside, in particular flush with the wall step 29 . This vertical web portion 22 increases the wall step 29 outwardly as viewed in the width direction of the food accommodating container. As a result, when viewed in the width direction, a larger overlap between the engaging piece 25 and the coupling socket 20 in the coupling state can be achieved, as shown in FIG 4 is shown.

A positioning aid stop for the actuating element, in particular a finger, is formed by the boundary edge 21 . This means that preferably a contact area 31 ( 3 ) is reached on the actuating surface 19 by this actuating element almost automatically. In particular, this means that the middle of a fingertip of a finger is essentially in the middle of the rear Actuating partial surface 19b is placed. This is quasi specified by the boundary edge 21 .

As moreover in 3 can also be seen, an upper edge 32 of the limiting web 21 is formed in one plane. In particular, this upper edge 32 extends in a plane in which the front partial actuating surface 19a also extends in a planar and planar manner.

As mentioned above, in 4 the partial section I in 2 shown. The coupling state between the coupling element 18 and the coupling receptacle 20 is shown here.

In figure 5 the coupling state between the coupling element 18 and the coupling receptacle 20 is shown in a frontal sectional view. In this regard, a sectional view along the section line VV in 2 shown. A sectional view in the area of the coupling device 14, which is formed between the vertical side wall 10 and the front wall 13, is thus shown. The same applies to the following explanation for the coupling between the side wall 11 and the front wall 13.

The increased height of the wall step 29 in the width direction due to the delimiting web 21, in particular the vertical web part 22, can be seen. As a result, the immersion depth of the coupling element 18, in particular of the engagement piece 25, in the coupling receptacle 20 is increased.

If an actuating element, for example a finger, is then pressed from the outside onto the actuating surface 19 in the area 31, in particular the rear partial actuating surface 19b, and a force is thus generated in the width direction, the coupling element 18 is pressed inwards. This is done until the in figure 5 symbolically and dashed shown release state of the coupling element 18 is reached. In this release state, the coupling element 18 does not dip into the coupling receptacle 20 in the width direction.

The front wall 13 can then be removed from the container trough 7 in the depth direction (z-direction). In this context, it is also possible that Coupling element 18 can be carried out in a gap 34 between a lateral edge area 33 or a wall part of the front wall 13, in which the coupling receptacle 20 is formed, and the side wall 11. In particular, it is provided in this context that the height of the delimiting web 21 measured in the width direction is designed such that this coupling element 18 can be guided forwards past the edge region 33 in this intermediate space 34 in the depth direction in this released state.
