Description

One aspect of the invention relates to a household refrigeration appliance with an outer wall and with an inner wall. The inner wall delimits an accommodating space for food in the household refrigeration appliance. In particular, the inner wall has an opening. A cover of the household refrigeration appliance is arranged in a gap formed between an outside of the inner wall and an inside of the outer wall. The cover is a separate component from the inner wall. With the cover, the opening to the intermediate space is covered. The opening is delimited by a circumferential collar wall. This collar wall is formed in one piece with the inner wall. It protrudes from the outside of the inner wall into the space. Furthermore, the invention relates to a method for installing a cover on an opening in an inner wall.

In the case of domestic refrigeration appliances, it is known that inner walls are known, for example, as walls of an inner container. Such an inner container delimits a receiving space for food with its walls. This can be, for example, a refrigerator compartment or a freezer compartment. Another example of an inner wall of a household refrigeration appliance can be an inner lining of a door. Thermally insulating material is usually placed in an intermediate space between such an inner wall and an outer wall of a household refrigeration appliance. This can be insulation foam, for example.

In order to be able to install additional functional units of the household refrigeration appliance, in particular on the inner wall, after such a foaming process, in which the insulating material is introduced into the intermediate space, such openings are required. This then also creates a volume range for these functional units. These openings must be made before the foaming process. For example, they are created during injection molding or deep drawing of the inner wall. In order to prevent during the foaming process that, for example, the insulating foam emerges from the intermediate space through this opening, these openings are usually covered. It is known to use adhesive tapes, for example. In particular, backing parts are also known in this context. These are on the foam side and are therefore arranged in the intermediate space and completely cover such an opening in an inner wall. This is intended to prevent insulation foam introduced into the intermediate space from passing through the opening. Backing parts are known in a wide variety of configurations and shapes. It depends on which functional units are to be subsequently installed on the inner wall and in the area of the opening. In this context, both smaller openings and also smaller backing parts are known, as well as larger openings and larger backing parts in this respect. In order to also be able to fasten such backing parts to the inner wall in a mechanically stable manner, a wide variety of concepts have also been implemented.

From the DE 10 2018 206 195 A1 a trough-shaped backing part is known. This is intended to cover an opening in an inner wall from the intermediate space. For this purpose, outwardly bulging beads or blind holes are formed on opposite side walls of a collar wall that frames or surrounds the opening. Latching means, which are formed on the trough-shaped backing part, engage in this. On these opposite side walls, the beads are formed in the same position and are also of the same shape. During assembly, the backing part is thus brought up to the inner wall in a quasi-linear manner and the latching elements formed on opposite sides snap into the beads at the same time.

In the concept shown there, however, a certain play of the mounted backing part can occur on this collar wall in a direction perpendicular to the surface plane of the opening.

It is the object of the present invention to create a household refrigerating appliance in which the positional arrangement of such a cover on a collar wall which surrounds an opening is improved.

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

One aspect of the invention relates to a household refrigeration appliance. The household refrigeration appliance has at least one outer wall. It has at least one inner wall that is separate therefrom. The inner wall limits the space for storing food in the household refrigeration appliance. In particular, the inner wall directly delimits this receiving space. The inner wall has at least one hole or a continuous opening. A gap is formed between the inner wall and the outer wall. This gap is formed between an outside of the inner wall and an inside of the outer wall. The household refrigeration appliance also has a cover. This is a separate component from the inner wall and the outer wall. In particular, this cover of the household refrigeration appliance is arranged in the intermediate space. You can partially or fully in this Zwi be arranged schenraum. With the cover, the opening in the inner wall is covered towards the intermediate space, in particular completely covered. The opening is delimited by a circumferential collar wall. This collar wall is formed in one piece with the inner wall. The collar wall extends into the cavity from the outside of the inner wall. The collar wall has a first section. This first section is stepped like a staircase. This configuration forms a specifically shaped hinge part for a pivoting hinge, with which the cover can be pivoted when the cover is in the coupled state with the first section. A hinge is thus formed at the interface between the cover and the first section of the collar wall, with which the cover can be pivoted as intended during an assembly process from an intermediate assembly position into an end position. A configuration of this type therefore enables the cover to be fitted easily on this inner wall, in particular on the collar wall. In addition, this concept also ensures that the cover sits securely on the collar wall in the end position. This concept with the design of a pivoting hinge means, on the one hand, that the assembly is intended to be carried out in individual assembly steps and thus also at least partially with a rotary movement. On the other hand, this swivel bearing or this swivel hinge also ensures that the cover is seated more stably on the collar wall in the assembled end position. An unwanted game in this end position is avoided. This avoids any play between the cover and the collar wall that may occur as a result of manufacturing tolerances.

In one embodiment, the first portion of the collar wall is straight. In particular, it is stepped like steps over its entire length in this respect. As a result, a corresponding coupling can be formed between the cover and the step-like structure over the virtually entire length of this first section. As a result, the advantages mentioned above are achieved over the entire length of this first section. A mechanically particularly advantageous concept is thus made possible both with regard to the assembly steps to be carried out starting from an intermediate assembly position into the end position and in the assembled end position a seat of the cover on the collar wall which is as play-free and sealed as possible.

In one exemplary embodiment, a stair profile of the stair-like stepped section is designed with a first vertical wall that cantilevers freely into the intermediate space. In one exemplary embodiment, this step profile has a horizontal wall adjoining this first vertical wall towards the opening. In one embodiment, the step profile has a second vertical wall. This, in turn, is designed directly adjacent to the horizontal wall. In one exemplary embodiment, the stair profile therefore has, in particular only, two vertical walls, between which a horizontal wall extends. With regard to its orientation, the vertical wall is oriented perpendicularly or substantially perpendicularly to the surface plane in which the opening extends. In particular, the horizontal wall is oriented in a plane parallel to the surface plane of the opening. With regard to the configuration with the vertical walls and the horizontal wall, this step profile is viewed in a cross section perpendicular to the longitudinal direction of the first section. This specific configuration of the step profile allows for simple coupling and covering with this step-like first section. In this regard, it is possible to easily thread the cover into this step profile. On the other hand, a safe and guided pivoting movement of the cover on this stair nosing is thereby achieved. This three-wall step profile then also makes it possible for the cover to reach its final position on the collar wall safely. This allows the cover to sit in a fixed position. In particular, this also enables a foam-tight arrangement of the cover on the collar wall.

In one exemplary embodiment, the stair profile has a step, in particular a single step. Through this stair step, a free space is formed under a horizontal wall of this stair step towards the opening. This is intended for engaging a coupling web, which is part of a hinge part receptacle of the cover for receiving the step profile, designed. A coupling web on the cover, which cross-section extends parallel to this horizontal wall, can therefore extend into this free space. It is therefore also achieved that this coupling web does not or does not have to extend into the opening in one exemplary embodiment. This position of the coupling bridge is thus shifted out of the opening, in particular into the intermediate space. In this context, the horizontal wall also forms a mechanical abutment. In particular, the coupling bridge can then be applied directly to the horizontal wall. In this regard, it rests directly against the underside of the horizontal wall facing the opening. On the one hand, a hinge bearing that is advantageous in this respect is made possible. A particularly simple rotary movement is thereby made possible. On the other hand, this concept in the mounted Final state in one embodiment, a large-area contact between an upper side of the coupling bridge, which faces the horizontal wall, and the underside of the horizontal wall, which faces the coupling bridge, is achieved. A seat that is mechanically stable in this regard, in particular without play, is then made possible in the end position. A foam-tight interface between the cover and the first section of the collar wall is preferably also achieved as a result.

In the assembled final state of the cover on the collar wall, the coupling web rests on the underside of the horizontal wall of the stair step facing the opening. In particular, it fits directly.

In particular, this coupling web and this horizontal wall extend parallel to one another in this assembled end state.

In one exemplary embodiment, the cover has a hinge part receptacle on a side wall. The stepped first section engages in this. The hinge part receiver has an entrance at which a receiver slot ends. This hinge part receptacle is preferably a cavity that is closed except for the entrance. This also improves the mechanical coupling between the cover and the first section. On the one hand, the receiving slot enables the first section to be easily inserted through the hinge part receptacle. On the other hand, due to this design, this input is not dimensioned so large that an undesirably wobbly coupling would be possible and thus only insufficient pivoting of the cover about this hinge would be feasible. Because this hinge part receptacle is a self-contained hollow space that only has this entrance, an undesired passage of insulating foam at this interface can be avoided. The penetration of insulating foam via this interface from the intermediate space into the opening is also avoided in an improved manner as a result.

In one exemplary embodiment, in the assembled end state of the cover, this first freely cantilevered vertical wall of this first section is completely accommodated and arranged in the hollow space of the hinge part receptacle on this step-like first section. The horizontal wall of this first section is also arranged completely within this hinge part receptacle. In one embodiment, the second vertical wall extends out from the entrance of this hinge part receptacle. In particular, this second vertical wall is therefore arranged on both sides of the entrance and is therefore arranged partly inside the hinge part receptacle and partly outside the hinge part receptacle. This achieves an advantageous coupling concept. Both the pivoting movement is thereby made possible in a defined manner and the mechanical coupling is achieved in a stable and reliable manner.

In one embodiment, an inner bearing surface of the first vertical wall bears against an outside of a boundary wall that bounds the area of the hinge part receptacle. This advantageously achieves further support for the fixed position of the cover on the collar wall in the final assembled state. In addition, this mechanical principle further improves the foam-tight interface between the cover and the collar wall.

In one embodiment, this inner abutment wall faces an opposite portion of the collar wall.

In one exemplary embodiment, in the fitted final state of the cover on the collar wall, a labyrinth coupling that is tight for an insulating foam that is introduced into the intermediate space is formed by the hinge part receptacle and the first part engaging therein. This labyrinth coupling is advantageously formed in one exemplary embodiment by the angled interlocking of the named components of the cover on the one hand and the stepped first section on the other hand. This positively supports a more stable mechanical coupling and the foam-tight interface.

In one embodiment, the cover is formed in one piece. In particular, it is made of plastic. In particular, it can be an injection molded component. In particular, it is manufactured in one piece. In one embodiment, the cover is formed as a trough-like or trough-shaped part. This cover thus has a base wall or a bottom wall. A peripheral wall protruding from it borders on this. This is formed by different side walls. In one embodiment it can be provided that the cover additionally has a peripheral sealing flange. This is formed on the outside of the side walls. In the assembled final state of the cover, this rests against the inner wall on the outside of the inner wall. Thus, the foam-tight design of the interface between the cover and the opening is further supported. In particular, this sealing flange or this sealing screen is elastic.

In one embodiment, the collar wall has a second, in particular rectilinear, section. This second section is the first th section opposite. In one exemplary embodiment, a plurality of snap-in elements are formed on this second section. Counter-snapping elements, which are formed on a side wall of the cover, can be snapped with these snapping elements. A concept is thus provided in which snap connections are formed between the snap elements and the counter-snap elements on one side. A hinge is formed on the opposite side, which on the one hand enables the cover to be pivoted, starting from an intermediate assembly position into the end position. On the other hand, in the final assembled state, a coupling concept that differs from snap connections is realized. This is achieved by engaging the stepped first section in the hinge part receptacle. In particular, a mechanical labyrinth coupling, which differs from a snap connection, is thus formed at this point. Different mechanical coupling concepts are thus formed between the cover and the collar wall on opposite sections of the collar wall.

This is particularly advantageous in that when the cover is pivoted about the hinge formed when the snap elements and the counter-snap elements are then oppositely snapped in place, the coupling web on the cover is also pressed against the step-like first section. As a result of the snapping, a force-loaded pressing against one another with specific elements is also achieved on the opposite mechanical coupling side in the region of the hinge. On the one hand, this is the pressing of the coupling bridge against the horizontal wall.

In one exemplary embodiment, the other contact surface of the first vertical wall of the step-like first section is then additionally pressed against an outside of a boundary wall that bounds the hollow area of the hinge part receptacle. This enables the cover to be seated in a particularly fixed position and snugly on the collar wall. This promotes a particularly play-free positioning of the cover on the collar wall.

In one embodiment, the snap-in elements are designed as snap-in receptacles. They are realized in particular by blind holes formed in the second part of the collar wall. These blind holes are formed on the outside. They are thus formed in the second section facing away from the opening. A counter-snapping element, which protrudes outwards from a side wall of the cover and is thus oriented away from the first section, thus engages in this blind hole for snapping.

In one embodiment, the cover is double-walled at least on the side opposite the hinge part receptacle. In this regard, an inner wall, ie a boundary wall, and an outer wall spaced therefrom, ie the side wall, are formed. The two walls are oriented parallel to each other. The at least one counter-snapping element is integrally formed on an outside of the inner wall, which faces the outer wall. The counter snap element extends out from the surface of the outside of the inner wall towards the outer wall. In the final assembled state, one embodiment provides that the second section of the collar wall extends into the cavity or into the slot between the inner wall and the outer wall of the cover.

In one embodiment, in the final assembled state, the first section is arranged in a gap between the inner wall and the outer wall of the cover. These inner wall and outer wall are each boundary walls. You thus limit the hinge part recording. In an advantageous exemplary embodiment, a corresponding construction is implemented on the cover, at least on the opposite side. There, too, the snap elements and the counter-snap elements are formed in a free space between an inner wall, ie an inner boundary wall, and an outer wall, as a side wall, of the cover. This construction also enables improved mechanical stability and a more foam-tight arrangement.

In particular, in one exemplary embodiment, the cover has such a double-wall structure all around. A third section of the collar wall and a fourth section of the collar wall can then dip into the two further double-wall sections.

In one embodiment, the first portion of the collar wall is oriented parallel to the second portion.

In one exemplary embodiment, the collar wall has four sections. In this regard, a third section and a fourth section are formed. The third section and the fourth section respectively connect the first section and the second section to one another. The third section is oriented parallel to the fourth section. In particular, in one embodiment, the collar wall is designed as a square frame.

In one embodiment, the height of the first section, which protrudes into the intermediate space, is smaller than the height of the second section, which is measured in the same direction in this regard. Thus, the collar wall is formed with different heights. By making this first section lower, easier coupling to the cover can be achieved. A rotational movement about this hinge bearing is also made easier in this way. As the second section is higher in this regard, a mechanically improved and large-area overlap between the cover and the second section can be achieved. A mechanically more stable connection, in particular by means of snap connections, is also improved in this area as a result.

In one embodiment, the third section and the fourth section of the collar wall are designed to decrease continuously in their respective height. This can be seen in particular at an end where the third section and the fourth section are connected to the second section towards those ends which are respectively connected to the first section. This continuous reduction in height of the third section and the fourth section is therefore formed in such a way that these two sections have the smallest height at the ends that open onto the first section. The ends at which the third and fourth sections meet the second section are at their greatest height.

In one exemplary embodiment, the inner wall is a wall of an inner container of the household refrigeration appliance. In one exemplary embodiment, the outer wall is a wall of an outer housing of the household refrigeration appliance. The inner container is in particular made in one piece, in particular made of plastic. For example, it can be made by deep drawing or injection molding. In one exemplary embodiment, the outer housing is made of metal, in particular sheet metal. The outer housing and the inner container are separate components from one another.

In another exemplary embodiment, the inner wall can be an inner lining of a door of the household refrigeration appliance. When the door is closed, this inner wall in the form of the inner paneling of the door delimits the storage space for food. In the exemplary embodiment, an outer wall can be an outer lining of the door. An intermediate space is also formed between this inner lining and the outer lining, in which thermally insulating material is introduced.

A further aspect of the invention relates to a method for assembling a household refrigeration appliance, in particular a household refrigeration appliance according to the aspect mentioned above or an advantageous exemplary embodiment thereof. To mount the cover on the inner wall, the cover is coupled to the first section of the collar wall with the hinge part receptacle. This cover, which is then arranged at an angle on the collar wall in an intermediate assembly position, is then pivoted about this pivot bearing or this coupling bearing. This continues until the cover is mechanically coupled to a second section of the collar wall on a side opposite the coupling bearing and is snapped there in particular, so that the fitted end position of the cover is set or reached on the inner wall.

During this pivoting of the cover, starting from the intermediate assembly position into the end position, this snapping in one exemplary embodiment also results in a quasi overpressing. In particular, on the opposite side, namely in the area of the pivot bearing, a coupling web, which is formed on an inner boundary wall of the hinge part receptacle, is thereby pressed against an underside of a horizontal wall of the step-like, stepped shape of the first section. In particular, in one exemplary embodiment it is also achieved that during this pivoting in the end position an inner contact surface of a first vertical wall of the step-like first section is also laid flat against an outer side of an inner boundary wall of the hinge part receptacle.

In one embodiment, the cover is brought from the outside of the inner wall to the inner wall and mounted there. It is also possible for the cover to be mounted on the opening, in particular the collar wall, coming from the inside of the inner wall. Thus, on the one hand, installation on the foam side is possible. On the other hand, in this context, assembly from the side of the inner wall opposite the foam side is also made possible. When installing on the foam side, there is also the option of supplying and installing or pre-assembling the components together with a wiring harness or cable harness.

The accommodation space of the household refrigeration appliance can be a refrigerator compartment or a freezer compartment. In addition, with this concept it is no longer necessary to additionally seal the interfaces between the opening and the cover with additional backing parts or adhesive tapes or the like. The desired function to be mounted The unit or component that is then to be installed in the opening and in particular in the cavity provided by the cover can then also be provided with an additional cable set or cable set for further assembly and then installed accordingly as an overall module.

In 1 an exemplary embodiment of a household refrigeration appliance 1 is shown in a schematic representation. The household refrigeration appliance 1 is designed for storing and preserving food. The domestic refrigeration appliance 1 has a housing 2 .

This housing 2 is an outer housing of the household refrigeration appliance 1. The housing 2 has side walls 3 and 4. These side walls 3 and 4 are examples of an outer wall of the household refrigeration appliance 1. The housing 2 can also have a top wall 5, a bottom wall 6 and a rear wall 7. These can also be examples of external walls.

In addition, the household refrigeration appliance 1 has an inner container 8 . This can be made of plastic, for example. It can be designed in one piece. The inner container 8 delimits a receiving space 9 for food. The receiving space 9 can be a refrigerator compartment or a freezer compartment, for example.

The inner container 8 has side walls 10 and 11 in the exemplary embodiment. The side walls 10 and 11 are exemplary embodiments of inner walls of the household refrigeration appliance 1. In addition, the inner container can also have a rear wall 12, a top wall 13 and a bottom wall 14. These can also be examples of inner walls.

In particular, the receiving space 9 is directly delimited by these walls 10 to 14 .

The inner container 8 is accommodated in the housing 2 . In this regard, an intermediate space 15 is formed between the housing 2 and the inner container 8 . Thermally insulating material is introduced into this intermediate space 15 . In particular, insulation foam is introduced in this regard.

In addition, the household refrigeration appliance 1 has a door 16 . The door 16 is arranged on the housing 2 in a pivotable manner. Door 16 is here for front closure of the receiving space 9 provided. The door 16 can have an inner lining 17 . The inner lining 17 is a further exemplary embodiment of an inner wall of the household refrigeration appliance 1. In addition, the door 16 has an outer lining 18. The outer cladding 18 is an exemplary embodiment of an outer wall of the domestic refrigeration appliance 1. An intermediate space is also formed between the inner cladding 17 and the outer cladding 18, in which thermally insulating material is introduced.

In addition, in the exemplary embodiment, an opening 19 is formed in an inner wall, here by way of example and not to be understood as exhaustive, in the side wall 11 . The opening 19 is covered here by a cover 20 towards the intermediate space 15 . A further functional unit of the household refrigeration appliance 1 can be installed in the niche formed in this way. This functional unit can be, for example, a sensor and/or lighting and/or a holding part or the like.

In 2 an embodiment of the cover 20 is shown in a sectional view. The cover 20 is in particular made in one piece. It can be made of plastic, for example. For example, it can be an injection molded component. This cover 20 is pot-shaped or trough-shaped here. It has a base wall, here a bottom wall 21 . Adjacent to this are side walls 22, 23, 24 and 25, as shown in 2 and 3 is shown. As a result, a volume space 26 of the cover 20 is limited. In addition, as shown in the perspective view in 3 it can be seen that the cover 20 is provided with a sealing screen 27 . This peripheral flange is intended for direct contact with an outside 38 ( 4 ) of the side wall 11 is provided.

In the sectional view according to 2 It can be seen that the side walls 22 and 23 are opposite. In particular, they are oriented parallel to one another. The same applies to the side walls 24 and 25.

The cover 20 has a hinge part receptacle 28 . This has a niche space 29 . This is intended to be designed in such a way that it is intended to accommodate a hinge part which is formed on the side wall 11 . Together with the niche space 29 , this hinge part receptacle 28 is a hollow space which has only one entrance 30 . The mentioned hinge part of the side wall 11 can be introduced into this entrance 30 . The hinge part receptacle 28 is delimited by a further inner delimiting wall 31 . This inner boundary wall 31 is arranged at a distance from the side wall 23 . It is formed directly on the inside of the bottom wall 21 . This double wall delimits the niche space 29 laterally. The inner boundary wall 31 has a coupling web 32 . The coupling web 32 is a freely cantilevered web. It delimits the entrance 30 as well as the free end of the side wall 23.

Also on the side wall 22 opposite the side wall 23, a further boundary wall 33 is offset inwards. This also delimits a niche space 34 . A double wall is also formed here as a result. Here, too, this niche space 34 is separated from the remaining volume space 26. A section of a collar wall 39 ( 4 ) in the assembled final state as intended. In addition, a counter-snapping element 35 is formed on this further boundary wall 33 . This protrudes into this cavity or niche space 34 . The counter-snapping element 35 projects in the direction of the outer side wall 22 .

As can also be seen, plate-like webs or spacer walls 36 extend in the cavity of the hinge part receptacle 29. In this regard, viewed in a connection direction between the boundary wall 31 and the side wall 23, they can also overlap with the coupling web 32. this is in 2 shown. Viewed perpendicularly to this, however, the coupling web 32 is spaced apart and positioned further towards the opening 19 than the respective lower end of the distancing walls 36. On the one hand, this can achieve stiffening and, on the other hand, the engagement and seating of a hinge part of the side wall 11 can be improved.

In one embodiment, webs 37 are also formed on the inside of the side wall 22 . These extend in the cavity 34 in the direction of the inner boundary wall 33. In this regard, they can also overlap with the counter-snapping elements 35 in a horizontal connecting direction between the boundary wall 33 and the side wall 22.

In 4 the side wall 11 is shown in a perspective view as an exemplary embodiment of an inner wall. An outside 38 is shown here. This outside 38 faces the intermediate space 15 . The opening 19 in the side wall 11 can be seen. It is completely delimited all the way around and is therefore completely bordered. It is provided that this inner wall has a collar wall 39 in the form of the side wall 11 , which is exemplary here. This is formed in one piece with the side wall 11 . The collar wall 39 delimits the entire circumference and thus interrupts The opening 19 does not have any clearance. The collar wall 39 extends out of the surface plane in which the side wall 11 is clamped. It is oriented into the intermediate space 15 and thus protrudes in the direction of the outer housing or the housing 2. Here it protrudes in the direction of an inside 4a of the side wall 4. In the exemplary embodiment shown, this collar wall 39 has a first section 40. The first section 40 is straight. In addition, the collar wall 39 has a second section 41 . The second section 41 is straight here. The second section 41 is opposite the first section 40 . The two sections 40 and 41 are thus arranged parallel to one another. In particular, they also have the same length. In addition, the collar wall 39 has a third section 42 and a fourth section 43 in the exemplary embodiment. The collar wall 39 is formed by these four sections 40, 41, 42 and 43 in the exemplary embodiment. The first section 40 is stepped like a staircase. This step profile 44 is formed over the entire length of the first section 40 . A hinge part 45 is formed by this step profile 44 . This is designed to be coupled to the hinge part receptacle 28 of the cover 20 as intended. In this regard, an interlocking is provided. The corresponding hinge bearing is formed for this purpose. As a result, the cover 20 can be pivoted about this pivot bearing or the hinge during the assembly process and brought into the end position.

In the exemplary embodiment, the step profile 44 has a freely cantilevered first vertical wall 46 . This thus extends more or less perpendicularly to the outside 38. It thus extends into the intermediate space 15 and towards the adjacent outer wall or side wall 4 of the housing 2. The stepped profile 44 also has a horizontal wall 47. This connects directly to the first vertical wall 46 . This horizontal wall 47 is oriented essentially parallel to the surface plane in which the opening 19 extends. Adjacent to this horizontal wall 47 is a second vertical wall 48 of the step profile 44 . This second vertical wall 48 again extends parallel to the first vertical wall 46. The second vertical wall 48 ends on the one hand on the horizontal wall 47 and on the other hand on the outside 38. A hinge part is formed by the first section 40. The distancing walls 36 also provide an insertion aid when inserting the first section 40 into the hinge part receptacle 28 .

In addition, it can be seen that in the second section 41 snap elements 49, 50 and 51 are formed. The number is only to be understood as an example here. These snap elements 49 to 51 are outwardly bulging blind holes. In this regard, they are bulged outwards, facing away from the step profile 44 . In addition, it can be seen that a wall height h1 of the first section 40 is smaller than a wall height h2 of the second section 41. The two other sections 42 and 43 are designed with a continuously changing height in this regard, from height h2 to height h1 the respective ends or connection points with the sections 40 and 41 go over.

In 5 is the representation in 4 shown upside down and looking towards the second section 41 . An inner side 52 of sidewall 11 is shown. The inside 52 faces the receiving space 7 .

In 6 is a sectional view of the view in 4 shown along section line VI-VI. The step profile 44 can be seen. A free space 45a is also shown here. This is formed under the horizontal wall 47 . So it is formed between the bottom of the horizontal wall 47 and the opening 19. This free space 45a is intended to be formed for the coupling web 32 to engage. The hinge part 45 integrated into the collar wall 39, in particular the first section 40, is shown.

In 7 an intermediate assembly state is shown. In this case, the cover 20 is only coupled to the first section 40 with the hinge part receptacle 28 . The step profile 44 engages in the hinge part receptacle 28 via the entrance 30 . This forms a pivot bearing. The cover 20, which in this intermediate assembly position is oriented at an angle to the opening 19, can then be pivoted towards the second section 41 according to the arrow P on the side of the side wall 22 opposite the pivot bearing. This second section 41 then engages in the cavity 34 of the cover 20 . Upon further downward pivoting, the snap elements 49, 50 and 51 then snap with the corresponding three separate counter-snap elements, of which the counter-snap element 35 can be seen here. In this regard, a bridging downwards also takes place, so to speak, so that these snap connections are formed.

In 8th is the sectional view of 7 to recognize. In particular, the engagement of the step profile 44, in particular the first vertical wall 46, is guided accordingly by the spacing walls 36 that are preferably present, and the pivoting movement that then takes place is also guided accordingly.

As in particular in 3 As can be seen, in one exemplary embodiment, an additional inner boundary wall 53 and an opposite further inner boundary wall 54 are also formed. As a result, an inner wall region is formed by the inner boundary walls 31, 33 and 53 and 54, between which a quasi-encircling free space or shaft is formed relative to the respective outer walls. This is separated from the volume space 26 . As a result, all four sections 40, 41, 42 and 43 can engage in this shaft of the cover 20. In particular, this takes place outside of the volume space 16. They are therefore limited both to the inside and to the outside by corresponding boundary walls 31, 33, 53 and 54 on the one hand and to the outside by the side walls 22, 23, 24 and 25.

When mounting is then based on 7 and 8th an introduction of these further sections 42 and 43 into the respective opposite partial areas of the shaft or the insertion area is also introduced. Therefore, this insertion portion 34 is formed on three side portions of the cover 20 . In this respect, the sections 42 , 43 and 41 dip into this shaft or into the insertion area 34 . In contrast, the first section 40 dips into the hinge part receptacle 28 .

In this context, in 9 The mounted end position of the cover 20 on the side wall 11, in particular on the collar wall 39, is shown in a perspective sectional view. The snapped state between the snap elements and the counter-snap elements is shown on one side. The end position of the hinge bearing is shown on the opposite page. As moreover in 9 and 10 can also be seen, in this assembled final state, an upper side 32a of the coupling bridge 32 rests against a lower side 47a of the horizontal bridge or the horizontal wall 47 . In addition or instead of this, it can also be provided that an inner contact surface 46a of the first vertical wall 46 bears flat against an outer side 31a of the inner boundary wall 31 . This also shows a correspondingly secure positioning in the area of this hinge bearing. As a result of the snapping, a leverage effect is also generated, so to speak, in which the coupling web 32 is pressed against the horizontal wall 47 from below.
