CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit, under 35 U.S.C. § 119, of German patent application DE 10 2017 205 089.6, filed Mar. 27, 2017; the prior application is herewith incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to a domestic refrigeration appliance with a chamber for holding food, which is delimited by walls of an inner container of the domestic refrigeration appliance. The domestic refrigeration appliance also has an inner lining, which comprises an air duct unit of the domestic refrigeration appliance.

Such a domestic refrigeration appliance is known from published, non-prosecuted German patent application DE 10 2014 224 648 A1.

Production tolerances can result when producing the inner container, which is generally produced as a single-piece plastic container, for example by deep-drawing. When the inner lining is subsequently incorporated in this chamber, which is delimited by the walls of the inner container, tolerances can therefore result. With conventional configurations compensation for such tolerances is associated with relatively large gap dimensions at the left-hand and right-hand edges when viewed from the front. Such configurations can also cause the inner lining to be positioned in an undesirable manner and mechanically stable fastening of the inner lining to be impaired.

SUMMARY OF THE INVENTION

It is the object of the present invention to create a domestic refrigeration appliance with an improved inner lining, the assembly of which can be achieved with better tolerance compensation.

This object is achieved by a domestic refrigeration appliance and a method as set out in the independent claims.

One aspect of the invention relates to a domestic refrigeration appliance with at least one chamber for holding food. The domestic refrigeration appliance has an inner container, the walls of which delimit the chamber. The domestic refrigeration appliance also has an inner lining, which is a separate unit from the inner container. The inner lining contains an air duct unit. This air duct unit allows air to be conducted in a defined manner in the domestic refrigeration appliance and thus also to be supplied to a specific chamber, so that this chamber can be fed specifically cooled air by this air duct unit. The air duct unit can thus be part of a cooling system of the domestic refrigeration appliance. The inner lining has a first lining wall and second lining wall separate therefrom. The inner lining is thus configured with multiple parts. These at least two separate lining walls are arranged adjacent to one another in the widthwise direction of the domestic refrigeration appliance, being positioned with an overlap with one another in this widthwise direction. Such a configuration means that the two lining walls form a continuous, unbroken wall but it is still possible to vary the width of the inner lining due to the separation of these two walls in the widthwise direction. This configuration therefore allows the inner lining to be adjusted for tolerances resulting in particular due to the inner container. This makes incorporation easier and undesirable gap dimensions can be avoided or adjustment for corresponding gap dimensions is improved due to the possibility of varying the width of the inner lining. This also allows more stable incorporation of the inner lining.

Provision can be made for the overlap between the two lining walls to be configured with play. This means in particular that the two lining walls can be arranged relative to one another in the widthwise direction in such a manner that the overlap is present between the lining walls but the lining walls are not brought together to the maximum. This specifically allows adjustment for different incorporation situations with the different tolerances that may be present and have to be compensated for. This configuration with an overlap with play specifically allows such a variation of width in a very advantageous manner.

It is then possible in particular for an assembly position reached between the two lining walls and also the overlap between these lining walls, which may also have some play, to be fixed. To this end a fixing unit can be provided, which is configured as a mechanical component, for example with brackets or latching elements. Fixing can also be achieved by introducing a thermally insulating material, in particular an insulation space, into a space between the inner container and an outer housing of the housing of the domestic refrigeration appliance. This causes the walls of the inner container to be pushed or deformed slightly in some instances in the direction of the chamber, so that the inner lining, which extends in the widthwise direction of the domestic refrigeration appliance, is then also fixed or clamped between the opposing vertical side walls of the inner container.

This is also very advantageous if the overlap is configured with play, as this allows a certain bringing together of the lining walls in the widthwise direction, without the inner lining arching or bulging to the rear or front.

Provision is preferably made for the overlap on the side facing the chamber to be covered by a cover that is separate from the lining walls. This conceals the overlap in the direction of the door and thus from a user's view. On the one hand this results in a less busy visual appearance. Significantly however it means that the overlap cannot be damaged and other objects cannot strike it directly. The mechanical coupling between the lining walls at this overlap is also protected as a result and damage or penetration by other foreign bodies can advantageously be prevented.

Provision is preferably made for the cover to be a cover plate. This gives rise to a very large, in particular single-piece part, which covers the entire configuration of the overlap at the front. Such a configuration also results in an intrinsically rigid and yet still flat part.

Provision is preferably made for the cover to have a front wall, which is part of the air duct unit and delimits an air duct volume of this air duct. This makes the cover multifunctional and even though the inner lining is intentionally to be made up of multiple parts, the number of components is minimized within these multiple parts.

Provision is preferably made for the cover to be arranged on at least one lining wall in such a manner that it can be removed non-destructively. This allows it to be removed and replaced in a reversible manner allowing access to parts of the inner lining behind this cover for maintenance work or assembly purposes. It also allows it to be cleaned and any parts that might collect in the air duct volume can also be easily removed.

Provision can be made for the cover to be attached or latched to at least one lining wall. This is a simple and yet highly functional mechanical connection, which can also be undone or restored easily by a fitter or user. This always ensures a safe assembly and disassembly scenario.

Provision is preferably made for one of the two lining walls to have a hollow holder, which is entered by an insertion element configured on the other lining wall to form an overlap. This configuration allows the lining walls to be coupled mechanically in a simple manner in this widthwise direction. Such a configuration also means that the complexity of the shape of the lining walls can be kept relatively simple, so that such geometries can be reproduced easily and accurately when producing a single piece, thereby preventing undesirable clamping or spreading when assembling these two lining walls with one another.

Provision can be made for the hollow holder to be configured as a slot. In this context it is as it were a groove, into which the insertion element, which is then preferably a web or band or lug, can be inserted. This advantageously specifically allows the overlap in the widthwise direction over the entire height of the two lining walls in the heightwise direction, preventing undesirable holes or leakage at this overlap interface. This ensures the lining walls overlap in the widthwise direction over the entire height.

This configuration also ensures a certain relative positioning of the lining walls in a further spatial direction, specifically the depthwise direction, so that these lining walls do not slide apart in an undesirable manner.

In a further embodiment provision can be made for the hollow holder to have a holder volume, which is delimited by at least one holder wall that can be deformed elastically in a defined manner. When the lining walls are in the assembled state relative to one another or with one another, the deformable holder wall rests in a pretensioned manner against a stop, which is configured on the other lining wall. This configuration not only brings about simple insertion, it also establishes an additional active mechanical connection, specifically generating a defined pretensioning force, which on the one hand favors the mechanical connection at the overlap and on the other hand stabilizes the relative position of the lining walls more effectively.

In a further embodiment provision can be made for the hollow holder to have a holder volume, which is delimited by at least one holder wall that can be deformed elastically in a defined manner. When the lining walls are in the assembled state relative to one another, the deformable holder wall is latched with a latching head in a latching holder, which is configured on the other lining wall. This is also an advantageous alternative embodiment, which allows secure positioning of the lining walls relative to one another and secure retention at the connection interface of the lining walls.

In a further alternative embodiment provision can be made for the hollow holder to have a holder volume, which is delimited by at least one holder wall. When the lining walls are in the assembled state, the holder wall rests against an elastically deformable stop, which is configured on the other lining wall and is pretensioned in the assembled state. This also has the advantages cited for the alternative embodiments mentioned above. In one advantageous embodiment provision is made for at least one lining wall to rest against a rod-type profile of the domestic refrigeration appliance, which is separate from the lining wall, at an edge facing away from the second lining wall. Such a configuration allows even greater assembly stability with the inner lining. In particular this profile part then rests against a wall, in particular a vertical side wall, of the inner container. This additional profile part further stabilizes the connection with a lining wall and more effective coupling to a wall of the inner container is achieved by way of this profile part.

This profile part is preferably configured as a hollow metal profile. In a sectional view perpendicular to a longitudinal axis of the profile part the profile part is configured as angular, in particular square, in its hollow body region. A lug can also be configured to project from this hollow body region, being able to serve to connect to other components.

Provision is advantageously made for this profile part to be a multifunctional part. In addition to the connection functionality for a lining wall it can also be used as a support part for a shelf which can be introduced into the chamber and divides the volume of the chamber into sub-volumes. As such a profile part is also very stable mechanically in respect of its configuration it can easily assume the support functionality not only for the at least one shelf but also for the stored goods positioned thereon.

A shelf in this context can also be configured at least partially of real glass for example.

The profile part is in particular configured as a single piece.

In one advantageous embodiment the inner lining has a third lining wall which is separate from the first lining wall and the second lining wall. The third lining wall is arranged with a further overlap with the second lining wall when viewed in the widthwise direction of the domestic refrigeration appliance. Such an embodiment allows the advantages cited above to be achieved even more effectively and tolerances can be compensated for particularly advantageously.

When viewed in the widthwise direction the second lining wall is advantageously arranged between the first and third lining walls and only the second lining wall is additionally also part or a boundary wall of an air duct volume of the air duct unit. With such a configuration the air duct unit is thus configured in the center of the inner lining when viewed in the widthwise direction.

Provision can be made for the second lining wall not to be configured as even but to be shaped as specifically uneven. It is therefore possible to create a corner-free contour with this uneven shape, as is the case for example with a channel. A specific angular shape can also be configured, for example a trapezoidal shape

Provision is preferably made for the second lining wall to be a rear wall of the air duct unit when viewed in the depthwise direction, being advantageously covered at the front by the separate cover already mentioned above. With such a configuration therefore the front of the air duct volume is delimited by a boundary wall in the form of the cover and the rear is delimited by a boundary wall in the form of the second lining wall.

In one advantageous embodiment provision can be made for the domestic refrigeration appliance to have a further separate rail or strip, which is arranged on the outside of the abovementioned profile part and is thus arranged at a distance in the widthwise direction from the lining wall which opens out at the profile part. Thus with such a configuration a gap is formed on a front wall of the profile part between this lining wall opening out thereon and the additional strip at a distance therefrom in the widthwise direction. This gap therefore allows access to the profile part at the front and makes it possible to suspend or otherwise arrange an abovementioned shelf from or on the profile part. This further strip is preferably configured as a single piece and extends over the entire height of the lining wall. In particular this strip can be configured as L-shaped in cross section.

Provision can be made for the mechanical connection of a lining wall to a profile part to be implemented by a plug-type connection or a latching connection.

The air duct unit is preferably what is known as a multi-airflow system. Such a configuration allows a very regular air distribution in the chamber.

The domestic refrigeration appliance preferably has a second chamber for holding food, this being separated from the first chamber. Provision is made in particular for the two chambers to be configured one above the other when viewed in the heightwise direction of the domestic refrigeration appliance. Provision can be made in particular for the upper chamber to be a chiller compartment. This can be closed in particular by two separate doors, which are each arranged pivotably on the housing. The two doors are arranged at the same height in the heightwise direction and adjacent to one another in the widthwise direction and can be actuated independently of one another. They can each be pivoted by way of their own vertical rotation axis. The further, in particular lower, chamber is preferably a freezer compartment. It can preferably be closed by a further front door. Provision can preferably be made here for this further door to be a front wall of a drawer, which can be pushed into and pulled out of this second chamber in the depthwise direction.

Provision can also be made for the domestic refrigeration appliance to have at least one third chamber, which can also be closed by an again separate door, which can be actuated independently of the abovementioned other doors, thereby allowing individual access to this third chamber. Provision can also be made in particular here for this further door to be a front wall of a drawer preferably provided here too.

A further aspect of the invention relates to a method for producing a domestic refrigeration appliance, wherein an inner container is provided, which delimits a chamber for holding food by means of walls. The domestic refrigeration appliance is configured with an inner lining, which contains an air duct unit. The inner lining is incorporated in the chamber. The inner lining is provided with a first lining wall and second lining wall that is separate therefrom. The two lining walls are arranged adjacent to one another in the widthwise direction of the domestic refrigeration appliance and are positioned with an overlap with play with one another in this widthwise direction. This play orients these lining walls in an assembly position relative to one another in the overlapping state and this assembly position is subsequently fixed. Such a procedure allows more effective compensation for production tolerances of individual components of the domestic refrigeration appliance, in particular of the inner container, and the inner lining can be incorporated very accurately and without undesirable position tolerances.

The terms “top”, “bottom”, “front”, “rear”, “horizontal”, “vertical”, “depthwise direction”, “widthwise direction”, “heightwise direction”, etc. specify the positions and orientations present when the apparatus or appliance is used and arranged in the correct manner and for an observer standing in front of the appliance and looking in the direction of the appliance.

The features and feature combinations cited above in the description and the features and feature combinations cited in the following in the description of the figures and/or simply shown in the figures can be used not only in the combination specified in each instance but also in other combinations without departing from the scope of the invention. Thus embodiments which are not shown specifically in the figures and described but emerge and can be generated from the embodiments described by way of separate feature combinations should also be considered to be included in and disclosed by the invention. Embodiments and features which therefore do not have all the features of an originally formulated independent claim should therefore also be considered to be disclosed. Embodiments and feature combinations, in particular those resulting from the embodiments set out above, which go beyond or deviate from the feature combinations set out in the claim references should also be considered to be disclosed.

 DETAILED DESCRIPTION OF THE INVENTION

Identical elements or those of identical function are shown with the same reference characters in the figures.

Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a schematic diagram of a domestic refrigeration appliance 1. The domestic refrigeration appliance 1 here is configured as a combined refrigerator/freezer. The domestic refrigeration appliance 1 has a housing 2, which has an outer housing 3 and an inner container 4. Configured between the outer housing 3 and the inner container 4 is a space 5, which is at least partially filled with a thermally insulating material, in particular insulating foam.

The inner container 4 has multiple walls, here specifically a first vertical side wall 6, an opposing second vertical side wall 7, a rear wall 8, a bottom wall 9 and a top wall 10. The inner container 4 is configured, preferably deep-drawn, as a single piece, in particular made of plastic.

At the front the inner container 4 has a loading opening 11, through which goods to be stored can be introduced into and removed from a chamber 12 for holding food delimited by the abovementioned walls 6 to 10. In the illustrated exemplary embodiment the chamber 12 is a first chamber, in this instance a chiller compartment for example.

In the illustrated exemplary embodiment this first chamber 12 can be closed by a first door 13 and a second door 14 that is separate therefrom. The two doors 13 and 14 are in particular visible front parts, which can be actuated independently of one another. In the present exemplary embodiment they close a single, continuous chamber 12. The two doors 13 and 14 can each be pivoted by way of a pivot axis oriented in the heightwise direction (y-direction) and are thus arranged pivotably on the housing 2.

In the illustrated exemplary embodiment the domestic refrigeration appliance 1 has a second chamber 15, in this instance a freezer compartment. In the illustrated exemplary embodiment this second chamber 15 is arranged below the first chamber 12 in this abovementioned heightwise direction. The second chamber 15 is also delimited by walls of an inner container and can be closed at the front by a door 16. The door 16 here is in particular a front wall of a unit configured as a drawer. This drawer can be pushed into and pulled out of the second chamber 15 in a linear manner in the depthwise direction (z-direction).

The domestic refrigeration appliance 1 also has an inner lining 17, which is a separate unit from the inner container 4 and is arranged in the inner container 4. It is thus arranged in the first chamber 12 here.

The inner lining 17 is thus also a separate unit from the rear wall 8.

FIG. 2 shows a perspective diagram of an exemplary embodiment of the inner lining 17. It is configured with multiple parts. It has a first lining wall 18. It also has a second lining wall 19. These two lining walls 18 and 19 are arranged with an overlap 20 with one another in the widthwise direction (x-direction), which is also the widthwise direction of the domestic refrigeration appliance 1.

Provision is made in the exemplary embodiment for the inner lining 17 to have a third separate lining wall 21. It adjoins the second lining wall 19 and is arranged with a further overlap 22 with the second lining wall 19 when viewed in the widthwise direction.

When viewed in the widthwise direction therefore the lining walls 18, 19 and 21 are arranged in a line with one another, but each with an overlap at their interfaces.

The inner lining 17 also has yet another separate component in the form of a cover 23, in this instance a cover plate. The cover 23 is arranged at the front and conceals the overlaps 20 and 22 at the front. When incorporated therefore the first lining wall 18, the third lining wall 21 and the cover 23 form visible parts in the chamber 12. The second lining wall 19 is covered by the cover 23 at the front.

The inner lining 17 also has an air duct unit 24, which is what is known as a multi-airflow system. In this context the air duct unit 24 has an air duct volume 25, which is delimited by boundary walls. The boundary walls here are formed by the second lining wall 19 and the cover 23.

Provision is also made in an advantageous embodiment for the inner lining 17 to have a first profile part 26 that is separate from the abovementioned walls and the cover 23. The first lining wall 18 opens out at this rod-type profile part 26, which is in particular a single-piece metal profile, being in particular fastened thereto, preferably being fastened thereto in such a manner that it can be removed non-destructively.

The inner lining 17 also preferably has a second profile part 27, which is configured in the same way as the first profile part 26. The further profile part 27 is configured in such a manner that the third lining wall 21 opens out at it, in particular is fastened to it in the same way as the first lining wall 18 is fastened to the first profile part 26.

A first strip 28, which is separate from the other components, is also provided, being arranged at a distance from the first profile part 26 and having no contact with the first lining wall 18. When viewed in the widthwise direction the first lining wall 18 and this strip 28 are arranged at a distance from one another so that a gap 29 is formed, through which a front face 30 of the first profile part 26 can be accessed at the front.

A further separate strip 31 is similarly provided, being arranged on the second profile part 27, in particular as in the abovementioned configuration being arranged at a distance in the widthwise direction from the third lining wall 21. A gap 32 is preferably formed here too, being accessible at the front and through which a front face 33 of the second profile part 27 is accessible.

Shelves or separating plates (not shown), which can be introduced into the chamber 12, can be fastened to, for example suspended from, the profile parts 26 and 27 by way of these gaps 29 and 32.

FIG. 3 shows an enlarged diagram of a partial detail III in FIG. 2. It can be seen here that the overlap 20 is configured with play in this widthwise direction. In the illustrated exemplary embodiment the first lining wall 18 has a hollow holder 34, configured here as a slot or groove, on the side or edge facing the second lining wall 19. Configured on the side or edge of the second lining wall 19 facing the first lining wall 18 is an insertion element 35 provided for engagement and molded on as a single piece in the form of a lug or web. In the coupled state with overlap in the widthwise direction this insertion element 35 enters the hollow holder 34.

It can also be seen that the second lining wall 19 has a web 36 that projects forward and is thus oriented in the depthwise direction, the cover 23 being connected mechanically thereto with a coupling web 37. Provision is thus made for the second lining wall 19 and the cover 23 to overlap in the depthwise direction (z-direction), in order to establish a mechanical connection here too. Provision can be made for the cover 23 to be attached or latched to the second lining wall 19. To this end corresponding latching elements can be molded as a single piece onto these webs 36 and 37. The configuration is also similar in the region of the further overlap 22, for which see the description given relating to the overlap 20 in FIG. 3.

FIG. 4 shows an enlarged diagram of the partial detail IV in FIG. 2. As can be seen here, the first lining wall 18 has a further web 38, which is molded on as a single piece and oriented in the depthwise direction, on its rear face. This forms a manner of stop, which rests against a side wall 39 of the profile part 26. The first lining wall 18 overlaps with the first profile part 26 in the widthwise direction, as shown in FIG. 2 and FIG. 4. The first lining wall 18 also rests against an abovementioned front face 30 of the profile part 26 and thus conceals parts of the profile part 26 at the front. A corresponding configuration, shown in FIG. 4 for the arrangement of the first lining wall 18 and the first profile part 26 as well as the strip 28, can also be seen for the third lining wall 21, the second profile part 27 and the further strip 31.

FIG. 5 shows a top view of a further exemplary embodiment of the inner lining 17 with sub-components, in particular in the region of the first lining wall 18, the second lining wall 19 and the cover 23. As can be seen here, the first lining wall 18 is inserted or latched into the first profile part 26, in particular using a corresponding coupling means 40.

The mechanical coupling between the first lining wall 18 and the second lining wall 19 is configured in an alternative manner here. The hollow holder 34 here is different from the embodiment in FIG. 2 and FIG. 3. There is no slot-type or groove-type configuration here. Instead a holder volume 41 of this hollow holder 34 is delimited by an elastically deformable holder wall 42. The web 25 of the second lining wall 19 molded at the edge enters therein. A stop 43 is also molded as a single piece on the rear of the lining wall 19. The elastically deformable holder wall 42 rests against this in a pretensioned manner, so that a pressing force P acts in the direction of the arrow, as shown in FIG. 5. The pretensioning force causes the first lining wall 18 to be pressed onto the profile part 26.

FIG. 5 also shows the coupled state between the webs 36 and 37, being implemented in particular by a plug-type connection or a latching connection.

FIG. 6 shows a further exemplary embodiment in a view corresponding to the one in FIG. 5. In this embodiment the hollow holder 34 is again not configured in the manner of a slot or groove but is configured with a holder volume 41, as in FIG. 5. The holder wall 42, which is also elastically deformable here, is configured here at its front free end with a latching head 44, which latches in a latching holder 45, which is configured as a single piece on a rear face of the second lining wall 19. This also forms a pressing force or pretensioning force formed in the widthwise direction according to the arrow P, which presses the first lining wall 18 onto the first profile part 26.

FIG. 7 shows a further top view, similar to the views in FIG. 5 and FIG. 6, of a further exemplary embodiment. In this embodiment the first lining wall 18 is configured on its side facing the second lining wall 19 in the same way as the embodiments in FIG. 2 and FIG. 3, so that the hollow holder 34 is configured in the manner of a groove or slot here. The two holder walls, which delimit this hollow holder, are thus not elastic and not deformable here in particular. Provision is therefore made in the present embodiment for an elastically deformable stop 46 to be configured on a rear face of the second lining wall 19, resting against a front face of a holder wall 47 in a pretensioned manner. This again generates a pressing force or pretensioning force in the direction of the arrow P, so that the first lining wall 18 is again pressed onto the first profile part 26.

FIG. 8 shows an enlarged diagram of the partial detail III in FIG. 7.

This concrete elements, as described in relation to the exemplary embodiments in FIG. 5 to FIG. 8, which generate such a pretensioning force due to their elastically defined deformability, in particular also allow the overlap produced in the widthwise direction between the lining walls with play.

The descriptions given in relation to FIG. 5 to FIG. 8 also apply to the overlap 22 preferably present between the second lining wall 19 and the third lining wall 21, in particular in conjunction with the second profile part 27.
