The in that Any problems that arise are already in the DE 40 40 341 C2 adequately explained.

It is the object of the present invention to create a household refrigerator in which the specific freshness of food is improved.

This object is achieved by a household refrigeration appliance which has the features of claim 1.

A household refrigeration device according to the invention comprises an interior space for holding food which is delimited by the walls of an inner container. The household refrigeration appliance also comprises a first fresh food container, which is arranged in the interior and which can be closed by a first lid, which is part of the fresh food container. The household refrigeration appliance also includes a storage device with which the first lid can be raised and lowered in the interior for opening and closing the first fresh food container. The cover can be operated with a first operating element.

An essential idea of the invention is that the household refrigeration device comprises a second fresh-keeping container separate from the first fresh-keeping container, which is arranged at the same height as the first fresh-keeping container when viewed in the vertical direction and thus in the height direction of the household refrigerating appliance and laterally next to it when viewed in the width direction of the household refrigerating appliance the first fresh food container is arranged. The second fresh food container comprises a second lid by means of which the second fresh food container can be closed.

Such a configuration with a plurality of separate fresh-keeping containers can increase the individuality of the food storage, in particular for food that can be kept fresh longer by adjusting the humidity individually. Thus, at least two again different degrees of humidity can be set in the interior space, namely in the fresh food containers, which can be set independently of one another and which in turn can be set differently and independently of the degree of humidity in the rest of the interior outside the fresh food container.

The storage device comprises a central guide rail on which the two covers are movably mounted, the central guide rail being fastened to a plate-like cover. This embodiment achieves in a particularly advantageous manner that a storage device with fewer components is available, and very smooth guidance for both covers is made possible by one element. In addition, this common central guide rail also helps to stabilize the position of the lids with respect to one another, so that when the lids move, there is no jamming or spreading of one lid or both lids. The plate-like cover is arranged above the middle guide rail and above the two covers.

The middle guide rail is not attached directly to a wall of the inner container. This is advantageous in that there is no need to intervene on the walls of the inner container, for example by deforming or integrating a fastening element, and thus there is no impairment of the thermally insulating effect of the walls and the thermally insulating material located behind them. In this way, a weakening of the wall can also be avoided.

The middle guide rail: is attached to the cover in a non-destructive detachable manner, so that reversible assembly and disassembly, for example for cleaning purposes or maintenance work, can also be carried out easily.

According to the invention, the middle guide rail has a gripping element at a rear end, with which a rear edge of the cover is gripped for fastening the middle guide rail to the cover. As a result, simple assembly and disassembly is achieved and a mechanically stable fastening is nevertheless obtained. The encompassing element is in particular U-shaped.

The storage device preferably has a first lateral guide rail, by means of which the first cover is additionally supported for storage on the central guide rail. The storage device has, in particular, a second lateral guide rail, by means of which the second cover is additionally supported for storage on the central guide rail. This makes each one special A smooth and safe guidance is achieved and the lid can move smoothly.

The two lateral guide rails are preferably attached to opposite side walls of the inner container.

The guide rails and the front strip connected to them preferably form a support frame for the cover.

The cover is preferably a shelf, in particular made of glass.

The middle guide rail is preferably connected at a front end to a front strip on which at least the first operating element is arranged. As a result, the middle guide rail is securely attached at both ends and can absorb particularly high forces.

In particular, the first control element is designed as a push-push actuation mechanism for actuating the first cover.

The domestic refrigeration appliance preferably has a second operating element, separate from the first operating element, with which the second cover can be operated, and the second operating element is designed as a push-push operating mechanism for operating the second cover.

Both operating elements are preferably designed with the same push-push mechanism in each case, so that the following explanations on push-push technology for one operating element also apply to the other operating element.

Such a configuration of an operating element as a push-push operating element makes it possible to carry out very user-friendly operation. This is because the control element is also improved with regard to ergonomic and intuitive movement sequences of a user through this configuration. Especially with regard to the operating action in progress and the usually present position of a user in front of the fresh-keeping container, this embodiment of the Operating element also advantageously used a direction of movement of a user in order to be able to exert as uniform and directed force as possible for moving the operating element on the operating element in order to achieve the movement of the cover.

This is particularly beneficial with a push-push actuation mechanism. A push-push actuation mechanism is to be understood as meaning that, in the positions to be assumed by the operating element, a user always initially has to initiate a movement that is oriented in the same direction. This means that both in a first and in a second end position of the control element, in order to move this control element further out of the respective position, actuation must initially be carried out in the same direction in each case in order to then carry out the further movement sequence of the control element, in particular automatically or to be able to carry out independently.

This concept of the push-push actuation mechanism thus makes a particularly user-friendly contribution to the generation of the respective movement scenarios of the cover.

It is preferably provided that a front strip having the edge, on which the operating element is arranged, has a movement guide device for the operating element. Thus, the operating element is arranged on the one hand on the front strip and held there, on the other hand it can also perform a relative movement with respect to the front strip, which is achieved by the movement guide device. Such mechanical arrangements and interactions in particular favor the push-push mechanism.

It is preferably provided that the movement guide device has a carrier plate with lateral guide elements. This is a particularly noteworthy embodiment, since as a result, when the operating element is moved in a direction parallel to the lateral guide elements, these can be held and supported so that no jamming or spreading occurs. The straight-line movement guidance of the operating element, especially with such a push-push actuation mechanism, is particularly favored by such a circumferential lateral guidance. The design with a carrier plate also creates a very stable component, which can also hold and accommodate the guide elements in a stable manner, so that precisely with this plate-like, large-area configuration of lateral guide elements, a circumferential receptacle for the operating element is also created.

It is preferably provided that the operating element has a sliding carriage which is guided displaceably in the carrier plate. This, too, is a particularly noteworthy embodiment, since the operating element is accordingly designed in the manner of a plate in its mechanical coupling with the movement guidance device and the advantages mentioned above are thus once again confirmed. As a result, it is also achieved that this structure of the sliding carriage and the carrier plate can be used to implement a very flat design and yet a very smooth movement control of the two parts relative to one another is achieved.

In particular, it is provided that the operating element has a sliding block which is guided in a guide slot of the movement guide device, in particular the carrier plate. The push-push mechanism is particularly favored by such a design. The coupling between the control element and the motion control device is therefore very stable on the one hand, and on the other hand the transfer of motion from the control element to other components up to the final raising and lowering of the lid is very direct and therefore has low tolerances and little play.

In particular, it is provided that the guide link has a first stop point for the sliding block and, at the first stop point, the operating element is held in a shifted position pressed into the front strip. In this sliding position, the cover is arranged in the open state by the storage device coupled to the operating element. The push-push actuation mechanism is specified by this configuration in that it virtually specifies an end position, namely the displacement position of the operating element. In concrete terms, in this embodiment of the push-push actuation mechanism, this first displacement position is reached when the operating element moves in a straight line, which is then also retained positionally by coupling the sliding block with the guide link, even if the user lets go of the operating element . By then given again mechanical coupling of the movement guide device with the storage device, the cover is then also held in the open state.

A very simple operating sequence, namely moving the operating element in a straight line in one direction into the shifting position, enables the open state of the cover to run very easily and virtually without play and movement tolerances.

In a particularly advantageous manner, the guide link is designed as a heart curve. This is particularly advantageous in that the operating element can be held in two end positions, namely the above-mentioned displacement position on the one hand and a basic position on the other. By simply actuating the operating element in the same direction for both positions, both the basic position can be released in order to be able to move from this to the shifted position, which is then held automatically. Again starting from the displacement position, this displacement position is released by initially operating the operating element in the same direction and the operating element then moves from the displacement position into the basic position by moving in the opposite direction. This mechanism and the respective setting of the respective stated positions are achieved particularly easily by the heart curve and the respective actuation scenario for a user is particularly smooth and smooth.

It is preferably provided that the sliding carriage is arranged under the carrier plate of the movement guide device and the guide link is formed on an underside of the carrier plate facing the sliding carriage. The sliding block is arranged in particular on an upper side of the sliding carriage. Especially when the sliding carriage is also essentially plate-like and the carrier plate is present, a structure layered one on top of the other or a corresponding arrangement of the components can be achieved and a simple coupling element can be provided by the sliding block. In addition to a very compact and flat design, the mechanical operating principle and the respective relative displaceability of the named components to one another are particularly favored. Since the Operating direction of the operating element, in which it can be moved in a straight line both when operated from the basic position in the displacement direction by a user and when releasing the displacement position, preferably extends in a plane in which the displacement carriage or the carrier plate extend or in a parallel plane to it, a very simple movement control, which can proceed very smoothly and without spreading or jamming, is made possible. This again significantly favors the very user-friendly design and operation.

It is preferably provided that an engagement area is formed on an underside of the sliding carriage facing away from the carrier plate, in which a coupling part engages on an upper side of the cover, so that the cover is coupled in terms of movement to the operating element. This creates a very robust connection that enables the cover to be guided with low wear and tear over the long term.

In particular, it is provided that the engagement area is designed as a hollow connecting piece that protrudes downward. This is mechanically very stable and can accommodate a raised element on the top of the cover, if necessary reach around.

In particular, this hollow socket is designed like a chimney, which further improves the advantages mentioned above.

It is preferably provided that the operating element is held pretensioned by a spring in a basic position that is extended forwards with respect to the front strip and in a displacement position pressed into the front strip at least further than in the basic position. The shift position can be released by pressing the control element against the direction of movement from the shift position into the basic position and against the spring force. These simple straight-line movements lead to a simple actuation for a user.

In particular, it is provided that the operating element has a front cap that is connected to the sliding carriage. In particular, a non-destructive detachable connection, such as locking, be provided. This cap can then also be exchanged.

The operating direction or the operating direction of the operating element is preferably directed perpendicularly relative to the front strip. In particular, this means that the actuation direction and the longitudinal axis of the front strip are located in a horizontal plane and the longitudinal axis and the direction of movement are perpendicular to one another. The movement of the control element is thus achieved by pressing the control element in the horizontal direction into the interior.

The operating element is arranged in particular on a front horizontal edge of the front strip and can therefore also be moved in the horizontal direction perpendicular to this front edge.

In particular, the control element is arranged in its basic position on the front side protruding forward over the front edge of the front strip.

In an advantageous embodiment it is provided that a carrier plate of the movement guide device is arranged on an underside of a cover which extends with a front edge into the front strip. The cover can, for example, be formed as a plate that is transparent at least in certain areas and can be, for example, a glass plate or a plastic plate. The movement guide device is thus covered from above by the cover. In particular, the cover is also arranged under this cover, a vertical distance between the cover and the cover being such that the cover can be raised and lowered accordingly in order to be able to assume the open and closed positions without any problems. The cover also provides a compartment divider and thus a floor for that part of the interior space that is located directly above the cover.

It can be provided that the storage device has guide rails which are formed on a frame adjoining the front strip. In particular, the guide rails are positioned on this frame in such a way that when the operating element is actuated, a movement is transmitted to the cover in such a way takes place that this is movable along these guide rails and is thereby moved relative to the fresh food container in such a way that the open or closed state occurs and thus a relative raising or lowering of the lid to the fresh food container takes place.

In a particularly advantageous embodiment, it is provided that the storage device is designed external to the fresh food container and a support frame connected to the front strip. Thus, the direct connection of the lid to achieve lowering or raising is directly coupled to components that belong to the fresh food container or belong to a front strip with the support frame that directly receives the control element. In this context, the storage device can then be attached in a very stable manner and the motion control of the cover is made possible very precisely and without play or tolerance. Movement inaccuracies which may result from relative movements and which can lead to blocking or jamming, as can occur with components that are movable relative to one another, including the fresh food container and the front strip with the support frame, can thereby be prevented. Especially when the control element is also arranged on the front strip with the support frame and occurs due to a relative movement by pushing the control element into the front strip, such undesired tilting or spreading can be prevented with an external arrangement of the bearing device.

It is preferably provided that the storage device has guide rails which are formed on opposite inner sides of vertical side walls delimiting the interior space. This is a particularly advantageous embodiment which particularly brings about the advantages mentioned above. Suspension elements which are arranged on the cover engage in these guide rails and can be moved along them. The motion control is thereby promoted.

It is preferably provided that the guide rails are designed with notches in which the suspension elements for setting the closed state of the cover are arranged. As a result, the closed state is very defined and precisely achieved and also held accordingly. In particular, it is provided that support tracks on the guide rails are located higher than the notches are formed on which the suspension elements rest for setting the open state of the lid. Depending on the actuation of the operating element, the suspension elements can be displaced between the notches and the support tracks relative to the guide rails, whereby the entire cover is accordingly relatively displaceable.

The guide rails are preferably formed as projections or bulges formed in one piece on the inner sides of the inner container. This also reduces the number of components and enables the very exact positional arrangement of the guide rails.

It can be provided that the support tracks are oriented in a straight line and horizontally. In such a configuration, a return from the open state of the cover to the closed state and thus the transfer of the positional arrangement of the suspension elements from the support tracks into the notches of the guide rails by an automatic mechanism, for example a spring preload, is advantageous.

In a particularly advantageous embodiment it can be provided that the support webs are oriented at an inclined angle and in particular are oriented sloping downwardly towards the front from a rear end point closer to a rear wall of the inner container. In such a configuration, after the sliding position of the operating element has been released, the weight of the cover supports a movement starting from an open state of the cover into the closed state, in particular carried out completely automatically. Due to the oblique orientation of the support tracks, the suspension elements then slide forward along these tracks until they run into the notches and come to rest there, held there. An automatic transfer by a spring preload or the like is then no longer necessary here, but can also be provided in addition.

In particular, the suspension elements on the cover are formed as laterally protruding wing-like elements. Preferably, two such suspension elements are formed on each lateral edge.

A household refrigeration device according to the invention comprises an interior space for holding food which is delimited by the walls of an inner container. The household refrigeration appliance also comprises a fresh-keeping container for food which is arranged in the interior and can be closed by a lid. The household refrigeration appliance also comprises a storage device with which the lid can be raised and lowered in the interior for opening and closing the fresh food container. The cover can be operated with an operating element. An essential idea of the invention is to be seen in the fact that a front strip has a movement guide device for the control element and the movement guide device has a support plate with lateral guide elements, the control element having a sliding carriage which is slidably guided in the support plate. A particularly precise movement control is thereby made possible without spreading or jamming occurring during the relative movement of the operating element to the front strip. This enables a very user-friendly and permanently smooth motion control. With the information "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" etc. are those for the intended use and arrangement of the device and given positions and orientations given to an observer then standing in front of the device and looking in the direction of the device.

Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1 is shown in an exemplary representation of a household refrigerator 1, which is designed as a combined refrigerator-freezer. The household refrigerator 1 comprises a body 2 with an inner container 3. The inner container 3 delimits with its walls a first interior space, which is a cooling space 4, and a second interior space which is arranged below and is separated therefrom and which is a freezing space 5. The cooling space 4 is generally used for frost-free cooling of items to be cooled, preferably at temperatures between + 4 ° C. and + 8 ° C. The cooling space 4 can, however, also be designed as a zero-degree compartment, in particular for keeping fruit or vegetables fresh. The cooling space 4 is accessible when the door 6, which closes the space 4 at the front, is open.

The freezer compartment 5 is generally used to deep-freeze frozen food, for example at -18 ° C. The freezer compartment 5 is accessible when the freezer compartment door 7 is open.

In the cooling space 4, a first refrigerated goods or fresh-keeping container 8a is mounted such that it can be pulled out. The first fresh food container 8a comprises a pull-out first shell 38 and a lid 9a, with which the first fresh food container 8a and thus the shell 38 can be closed. As shown, an additional cover 10, for example in the form of a glass compartment floor, can be arranged over the first cover 9a.

In addition, the household refrigeration device 1 comprises a second fresh food container 8b, which is formed separately from the first fresh food container 8a. The second fresh food container 8b also comprises a pull-out second shell 39 and a second cover 9b, with which the second fresh food container 8b and thus the second shell 39 can be closed. The cover 10 is also arranged over the second lid 9b.

The first fresh food container 8a and the second fresh food container 8b are arranged at the same height in the height direction of the household refrigerator 1 and are arranged directly next to one another in the width direction of the household refrigerator 1.

The inner container 3 has two opposite vertical side walls 3a and 3b.

In Fig. 2 the cover 10 is shown in a perspective view. A front strip 11 is arranged on a front edge that faces the door 6. The cover 10 is thus preferably arranged extending into the front strip 11 in some areas, for example inserted therein.

The front strip 11, in particular made of plastic, also extends over the entire width of the cover 10. The front strip 11 also serves as a carrier for a first operating element 12a. The first operating element 12a is provided for operating the first cover 9a.

The front strip 11 also serves as a carrier for a second operating element 12b. The second operating element 12b is provided for operating the second cover 9b.

In the following, the actuation mechanism is explained only with reference to the first operating element 12a. The embodiment also applies to the second operating element 12b.

In Fig. 2 the first control element 12a is shown with a control element cap 13, which is accessible from the front and can be directly gripped and operated by a user. The first operating element 12a is designed as a push-push actuation mechanism for actuating the first cover 9a. In particular, it is thus provided that it can only be moved back and forth in the z-direction and is thereby held and guided accordingly in the front strip 11.

To do this, actuation along the arrow P is provided. In Fig. 2 a situation is shown in which the first operating element 12a is arranged in a basic position. This also means, for example, that the operating element cap 13 extends in the z direction in a raised manner to the front relative to the front strip 11 and thus protrudes to the front. Based on the representation in Fig. 2 a second end position can be set in relation to the basic position, which shows a first end position, which is a so-called shift position, as shown in FIG Fig. 3 is shown. In this shifted position, the operating element cap 13 is positioned further in the direction of the cover 10 and, in particular, the operating element cap 13 is arranged flush with the front strip 11 on the front.

The push-push actuation mechanism is in both end positions, as shown in FIGS. 2 and 3 are shown, the further actuation of the first operating element 12a by pressing it in a straight line in the horizontal depth direction and thus in the z-direction along the arrow P is only possible.

In the exemplary embodiment it is provided that the basic position as shown in Fig. 2 is held biased by a spring.

In the Fig. 3 The shown displacement position of the first operating element 12a is also designed to hold itself independently. Should based on the shift position according to Fig. 3 again the basic position according to Fig. 2 can be achieved, a user must first press the first operating element 12a again in the direction of the arrow P in order to be able to release this displacement position, and then after this release automatically a straight extension and return of the first operating element 12a in the in Fig. 2 shown basic position is reached.

This configuration is also, in particular, a component of the push-push actuation mechanism.

The first lid 9a can be raised and lowered by a storage device 14, whereby the opening and closing of the first fresh food container 8a is achieved. In the lowered state of the first lid 9a, the first fresh-keeping container 8a is thus closed from above, and it is open when the first lid 9a is raised. With such a configuration, the vegetables or fruit or fish or the like contained in the first fresh-keeping container 8a can be kept fresh for a longer period of time and do not dry out. The ones in the DE 40 40 341 C2 The problems explained can be positively influenced by this.

The first operating element 12a in its position and in particular in its design as a push-push actuation mechanism enables a particularly user-friendly actuation which, moreover, is also permanently robust and stable and runs smoothly.

In Fig. 4 FIG. 13 is a bottom view of a component representation such as that shown in FIG FIGS. 2 and 3 is shown. A first exemplary embodiment of a first operating element 12a is shown here. The operating element cap 13 is connected to a sliding part 15 in a non-destructive manner, for example by latching. The cap 13 thus covers this sliding part 15 from the front. In the exemplary embodiment shown, the sliding part 15 has a central web 16 on which a sliding block 17 is arranged on an upper side facing the cover 10. This sliding block 17 engages in a guide slot 18 designed as a heart curve in the exemplary embodiment. The guide slot 18 is arranged on an underside 19 of a carrier plate 20. The carrier plate 20 is preferably formed in one piece and integrally with the front strip 11. It is also arranged above the part 15 or the web 16.

In Fig. 5 is the execution according to Fig. 4 shown, whereby in contrast to the representation in Fig. 4 the first operating element 12a is shown in the shifting position.

In this context, the design of the guide slot 18 as a heart curve is particularly advantageous. Because the sliding block 17 and the resulting coupling between the first control element 12a and the support plate 20 enables a particularly precise and smooth relative displacement in the direction of the arrow P between the first control element 12a and the front strip 11. This also enables a corresponding relative displacement of the first cover 9a reached, which is mechanically coupled to the part 15 and / or the web 16.

In Fig. 4 a situation is shown in which the sliding block 17 is arranged in a second dead center or second stop point. Based on the representation in Fig. 4 is pressed on the front side in the direction of the arrow P on the first operating element 12a, the sliding block 17 moves in the guide slot 18 to a front first dead point or first stopping point 21, as in FIG Fig. 5 is shown. The push-push actuation mechanism, which includes the guide slot 18 in its specific shape and the sliding block 17, creates a self-retaining state of the first operating element 12a in the displacement position, as shown in FIG Fig. 5 shown is achieved. To solve this shift position, as has already been done to the FIGS. 2 and 3 has been explained, a movement in the direction of the arrow P is first required, and then depending on the push-push actuation mechanism, an independent movement against this arrow P takes place and the first operating element 12a again in the outwardly protruding opposite the front strip 11 raised self-holding basic position according to Fig. 4 is moved.

The parts 15 and 16 are assigned to a movement guide device 22 in a component-specific manner.

In particular, this independent return after releasing the shift position is according to Fig. 5 achieved by a spring acting in the z-direction, which then presses the actuating element or the first operating element 12a outwards due to the bias.

In Fig. 6 Another exemplary embodiment is shown in an exploded view, in which the configuration of the movement guidance device 22 differs from FIGS. 4 and 5 is. In this embodiment, no sliding part 15 with a further central central web 16 is provided, but a plate-like sliding slide 23 is implemented. A spring 24 is preferably again provided to bring about the already explained sequences of movements from the return of the first operating element 12a starting from the shifted position into the basic position.

Also in Fig. 6 the integral design of the carrier plate 20 with the front strip 11 can be seen.

In Fig. 7 FIG. 13 is a bottom view of the embodiment of FIG Fig. 6 shown, the first operating element 12a being shown here in the basic position.

In a particular advantage of this exemplary embodiment, it is provided that the carrier plate 20 extends to the rear opposite the front strip 11 and guide elements 25a and 25b are formed on the side edges 20a and 20b running parallel to the displacement direction P. In particular, these guide elements 25a and 25b are formed in one piece with the carrier plate 20. These guide elements 25a and 25b encompass the plate-like sliding carriage 23 at the edge, so that it cannot fall out downwards and is guided on both sides in the horizontal sliding direction according to the arrow P. This embodiment is particularly advantageous in that no undesired tilting about the axis of the arrow P occurs, so that the actuation can be carried out very smoothly and continuously for a user.

The coupling of the operating element cap 13 to the sliding carriage 23 is shown by latching elements 13a and 13b and 13c.

In an advantageous embodiment it is provided that an engagement area 26 is formed on an underside 23a of the sliding carriage 23 facing away from the cover 10. In the exemplary embodiment, this protrudes downwards and is designed like a chimney. It is thus a hollow engagement region 26 in which a counter-element, which is arranged on an upper side of the first cover 9a, can engage. This is a mechanical operative connection and coupling between the first operating element 12a and the first cover 9a achieved.

As shown in Fig. 7 can be seen, the direction of the displacement according to the arrow P in a plane or in a parallel plane in which the sliding carriage 23 and the carrier plate 20 extend.

In addition, it is provided that a further coupling area 27 is formed on the carrier plate 20. A guide pin 28, which can be guided in a guide track 29 in the carrier plate 20, extends in this from above downwards. This guide pin 28 is provided with an indicator plate 30 ( Fig. 8 ), which is arranged on the carrier plate 20, connected. As a result of the movement of the operating element 12 and the associated movement of the sliding carriage 23, this display plate 30 is also moved via this pin 28. This also results in a relative displacement of the display plate 30 to the cover 10, so that in this regard the display plate 30 can also optically indicate the respective existing state of the first cover 9a and thus the open or closed state of the first cover 9a. Through this optical field, which can be individually colored depending on the state of the lid, or a specifically colored area can be seen by the user depending on the respective position, a corresponding position of the first lid 9a can be recognized intuitively and quickly.

In this context, in Fig. 8 a perspective view of the embodiment according to Fig. 7 shown from above. The carrier plate 20, which covers the sliding carriage 23 from above, is shown.

In Fig. 9 FIG. 10 is a perspective sectional view along the line IX-IX of the embodiment in FIG Fig. 8 shown. As can be seen, a coupling part 92 is shown on an upper side 91 of the first cover 9 a, which is shown engaging in the engagement region 26. The carrier plate 20 is arranged so as to protrude from a front edge 10a of the cover 10 and is pulled slightly upwards, so that the cover 10 is also arranged, to a certain extent, slightly sunk and embedded therein. The guide slot 18 is formed on the underside 19, and the sliding block 17 sits in a front area of the sliding carriage 23 on an upper side 23b.

Furthermore, it can be seen that the spring 24 is arranged in a corresponding installation space which is box-shaped or semi-tubular.

In Fig. 10 is the execution of the components as they are in Figures 7 to 9 explained in a perspective from below. The sliding carriage 23 is removed from the operating element cap 13 so that the underside 19 of the carrier plate 20 can be viewed. The guide link 18 can be seen in the context. The arrangement and shape of the guide elements 25a and 25b can also be seen in detail in this context.

In the perspective view from below in Fig. 11 are the components as they are in Fig. 7 are shown. In contrast to the representation in Fig. 10 The sliding carriage 23 is then additionally arranged here. The half-tube-like or dome-like housing structure 31, which opens into the engagement area 26 and via which the spring 24 on the sliding carriage 23 is covered, is shown.

In Fig. 12 a specific embodiment of a storage device 14 is also shown in a further perspective sectional illustration in addition to the first cover 9a. This is a particularly advantageous embodiment, since the storage device 14 is arranged externally to the first fresh food container 8a and to the second fresh food container 8b and to the front strip 11 as well as to a carrier frame 32 which comprises the front strip 11. It is particularly advantageous that the storage device 14 is integrated with sub-components on the vertical side walls 3a and 3b. The storage device 14 is thus arranged externally to the components mentioned. The storage device 14 is also formed in side guide rails 33 and 40, which are first and second side guide rails. On opposite sides and thus on the vertical side walls 3a and 3b, with FIG Fig. 12 only the first lateral guide rail 33 is shown and in FIG Figures 13 and 14 the second lateral guide rail 40 is also shown, these guide rails 33 and 40 are designed to be integrated.

The first lateral guide rail 33 protrudes as an inwardly curved elevation from the side wall 3a into the interior space or into the cooling space 4. These first lateral guide rail 33 comprises two notches 35 on an upper side 34, with FIG Fig. 12 only the front notch 35 can be seen.

On the first cover 9a is on the opposite and the side wall 3a on the one hand and a central guide rail 41 ( Fig. 14 ) the storage device 14 on the other hand side edges 93 each have a suspension element 36 formed in one piece. This extends angled and wing-like to the side and according to the embodiment shown Fig. 12 the suspension element 36 is positioned lying in the front notch 35. A further suspension element in the rear region of the first cover 9a, which is formed on this side edge 93, is also arranged lying in a corresponding notch.

The configuration of the second cover 9b is corresponding, with the suspension elements facing the side wall 3b and the central guide rail 41 here.

However, it can also be provided that only a single suspension element 36 is formed on the side edge 93 and only one such suspension element is likewise formed on the opposite side edge. Adjacent to the notch 35, the upper side 34 of the guide rail 33 comprises a support track 37 which is higher than the notch 35 in the vertical direction and thus in the y-direction.

For the sake of clarity, in Fig. 12 the cover 10, which would be arranged above the cover 9a and 9b and would be arranged to engage both in the front strip 11 and in the lateral parts of the support frame 32, is not shown.

The in Fig. 12 The position shown is the first cover 9a closed. On the basis of this, the first operating element 12a can then be pressed in the direction of the arrow P, with the result that in particular Fig. 9 Coupling of the individual elements shown results in a displacement of the sliding carriage 23 in the direction of this arrow P. Due to the coupling of the engagement area 26 to the coupling part 92, the first cover 9a is then also displaced in this direction of the arrow P and thus to the rear. It is thereby achieved that the suspension elements 36 slide out of the notches 35 and get up onto the support web 37.

As a result, the open state of the first cover 9a is then automatically set since it is raised.

It can be provided that this support web 37 runs completely horizontally. In such an embodiment, it is then necessary that the return from the raised and thus opened state of the first cover 9a to the then lowered again and thus closed state of the first cover 9a by an additional auxiliary element, in particular by a spring, for example the spring 24 , he follows.

A particularly advantageous embodiment results from the fact that this support web 37 is oriented obliquely and, in particular, is oriented from the notch 35 to rise towards the rear. In such a configuration, due to the weight of the first cover 9a in the open state when the first control element 12a is actuated from the shifted position, an automatic return to the closed position of the first cover 9a is achieved, since the latter automatically returns to the closed position due to the weight and the obliquely oriented support track 37 slides forward again and the suspension elements 36 move into the notch 35. A spring preload or other auxiliary support for returning the first cover 9a to the closed state is then not required in this embodiment.

The functioning and thus the raising and lowering of the second cover 9b is analogous. The two covers 9a and 9b can be operated independently of one another by the respective operating elements 12a and 12b.

In Fig. 13 a perspective view of the fresh food containers 8a and 8b is shown. It can be seen that the middle guide rail 41 has an encompassing element 43 on a rear end 42 facing away from the front strip 11. This surrounds a rear edge 10a of the cover 10. The middle guide rail 41 is thereby attached to the cover 10. The middle guide rail 41 is not attached directly to a wall of the inner container 3.

As in Fig. 14 is shown, a front end 44 of the central guide rail 41 is connected to the front strip 11. The middle guide rail 41 instructs opposite sides each have guideways, with in Fig. 14 only the guide track 45 for a suspension element of the second cover 9b can be seen. With regard to the mode of operation of the guideway 45, the to Fig. 12 to the suspension elements and the first lateral guide rail 33 explained. <b> List of reference symbols </b> 1 Household refrigeration device 21st Breakpoint 2 Body 22nd Motion control device 3 Inner container 23 Sliding carriage 3a Vertical sidewall 23a bottom 3b Vertical sidewall 23b Top 4th Cold room 24 feather 5 Freezer 25a Guide element 6th door 25b Guide element 7th Freezer door 26th Intervention area 8a first fresh food container 27 Coupling area 8b second fresh food container 28 Guide pin 9a first lid 29 Guideway 9b second lid 30th Display panel 10 cover 31 Housing structure 10a rear edge 32 Support frame 11 Front strip 33 first lateral guide rail 12a first control element 34 Top 12b second control element 35 notch 13 Control element cap 36 Suspension element 13a Locking element 37 Support track 13b Locking element 38 first shell 13c Locking element 39 second bowl 14th Storage device 40 second lateral guide rail 15th Sliding part 41 middle guide rail 16 Middle bar 42 rear end 17th Sliding block 43 Wrap-around element 18th Leadership backdrop 44 front end 19th bottom 45 Guideway 20th Carrier plate 91 Top 20a Margin 92 Coupling part 20b Margin 93 Margin P arrow
