Description

Door with specifically arranged sealing element, as well as household appliance

One aspect of the invention relates to a door for a household appliance. The door has an outer panel. In addition, the door has an inner lining that is separate from the outer lining. The interior lining has an anchoring seat for an anchoring body of a sealing element of the door. The sealing element of the door is anchored with this anchoring body in this anchoring receptacle. In a horizontal section of the door, the sealing member extends on both sides of the width of an entrance of the anchoring seat, viewed in the direction of the width of the door. The sealing element has a first sealing part which, in this width direction, extends to one side beyond the width of the entrance. The sealing member has a second sealing part which extends to the other side beyond the width of the entrance in this width direction. The interior paneling has a first wall part, which in this horizontal section, coming from this one side, ends at the entrance of the anchoring receptacle. The interior paneling also has a second wall part which, viewed in horizontal section, ends at the entrance coming from the other side. A further aspect of the invention relates to a household appliance with such a door.

Doors for household appliances are well known. So it is known in household refrigeration appliances that a door has an outer lining and an inner lining. These delimit an intermediate space. Thermally insulating material is arranged in this intermediate space. In order for the door to be in sealing contact with a housing of the household refrigeration appliance in the closed state, such a door usually also has a sealing element. This can be a multi-chamber hollow profile and is anchored accordingly on the door.

Such a sealing element and a corresponding door are known, for example, from EP 3 569 757 A1. Wall parts that laterally border the anchoring receptacle in a horizontal section there are curved in many ways. In addition, a lateral edge strip of the outer paneling is designed in one layer. It is the object of the present invention to create a door for a household appliance which has greater rigidity or improved stability.

This object is solved by a door and a household appliance according to the independent claims.

One aspect of the invention relates to a door for a household appliance. The door has an outer panel. In addition, the door has an inner lining that is separate from the outer lining. The interior lining has an anchoring seat for an anchoring body of a sealing element of the door. The sealing element of the door is anchored with this anchoring body in this anchoring receptacle. In a horizontal section of the door, the sealing member extends on both sides of the width of an entrance of the anchoring seat, viewed in the direction of the width of the door. The sealing element has a first sealing part which, in this width direction, extends to one side beyond the width of the entrance. The sealing member has a second sealing part which extends to the other side beyond the width of the entrance in this width direction. The interior paneling has a first wall part, which in this horizontal section, coming from this one side, ends at the entrance of the anchoring receptacle. The inner lining also has a second wall part, which in horizontal section, coming from this other side, ends on the one hand at the entrance and on the other hand ends at a free edge of the inner lining. The free edge is thereby formed by a free end of the second wall part. This is the end that faces away from the entrance. The width direction is therefore in particular the direction in the horizontal plane in which the clear width between the opposite boundary ends of the entrance is measured.

In a horizontal section, the first sealing part preferably abuts a first contact point on an inside of the first wall part and the second sealing part preferably abuts a second contact point on an inside of the second wall part in a horizontal section. In one embodiment, the second contact point formed on the second wall part is arranged a maximum distance of 5 mm closer to an inside of a front panel of the outer panel than the first contact point, viewed in horizontal section in the depth direction of the door. Such a design of a door makes it more stable precisely in this interface area between the seal and the inner lining and between the inner lining and the outer lining. In this regard, the sealing element has improved positioning options on the left and right of the entrance of the anchoring receptacle due to the specifically formed contact points in this horizontal sectional illustration. As a result, the sealing element is also inherently stabilized and can also build up an improved sealing effect when the door is closed, in which this sealing element rests against a front flange of the housing of the household appliance.

In one exemplary embodiment, viewed in this horizontal section, the first sealing part bears against a first contact point on an inside of the first wall part. Viewed in this horizontal section, the second sealing part is preferably in contact with a second contact point on an inner side of the second wall part. In this horizontal section, these two contact points are offset from one another by a maximum distance of 5 mm in a direction perpendicular to this width direction, in particular in the depth direction of the door. They can therefore be arranged in the same or substantially the same position in this horizontal plane in this direction measured perpendicularly to the width direction.

The distance is thus a value in an interval between the interval limits of +/- 5 mm. Therefore, in the direction perpendicular to the width direction, in particular in the depth direction, the first contact point can be further forward than the second contact point in this horizontal section, or in another exemplary embodiment the second contact point can be further forward than the first contact point.

Viewed in the horizontal section, this anchoring receptacle can be formed in the manner of a blind hole. In three dimensions, it is particularly channel-shaped in this regard.

In one exemplary embodiment, the second wall part extends in a straight line when viewed in this horizontal section, ie the entire second wall part is designed in a straight line or flat in this horizontal section. This second wall part preferably extends in the width direction when viewed in horizontal section. This becomes one provided in this horizontal section rectilinear inside. Improved contact between the second sealing part and this second wall part is achieved by this geometric design. In this context, it is particularly advantageous that these contact points are positioned in the same or essentially the same position in the horizontal section in the direction perpendicular to the width direction.

In one exemplary embodiment, viewed in particular in this horizontal section, the second wall part has an end facing away from the entrance of the anchoring receptacle. This end is in particular arranged in a cantilevered manner. In one exemplary embodiment, it forms a marginal edge of the inner lining.

In addition, a second wall part shaped and oriented in this way also offers a larger area for the second sealing part to rest on. In particular, this larger area in the horizontal section as a line is particularly completely on the same layer in the direction perpendicular to the width direction. Even if this second sealing part rests against this inner side of the second wall part in the width direction with a certain position tolerance of the second contact point, it is still always positioned in the same position in the direction perpendicular to the width direction in the horizontal section.

In one exemplary embodiment, the second wall part is located in this horizontal section in the direction perpendicular to the width direction and therefore, particularly viewed in the depth direction, at the same depth as the entrance of the anchoring receptacle. This exemplary embodiment makes it possible for the two contact points, viewed in the horizontal section, to be practically in the same position or essentially the same position as the entrance in this depth direction. This further improves the advantages mentioned above.

In one embodiment, the second abutment is depthwise further from the inside of the faceplate of the outer panel than the first abutment. This also includes an alternative in which the second contact point is offset to the rear relative to the first contact point. In one embodiment, viewed in this horizontal section, the second contact point is further away from the entrance than the first contact point, viewed in the width direction of the door. As a result, elastic deformations of the sealing element, which occur when the door is closed and the sealing element bears against or is laid against the front flange of the housing, are supported. A more defined and more directed deformation of the sealing element is thereby made possible.

Basically, it should be mentioned that the contact points are local contact points of the sealing parts on the insides of the wall parts. Considered individually, the sealing parts can each be larger in this respect. In particular, however, they are not in full contact with the inner sides. The two contact points are therefore only partial areas of the total areas of the sealing parts. In this regard, the sealing parts have surface areas facing the inner sides. In particular when the door is open and therefore when the sealing element is not under load, these surface areas do not lie against the inner sides over their entire surface. Those partial surface areas of these surface areas that are in contact with the inner sides of the wall parts then define the surface sizes of the contact points. The advantages mentioned above are supported by the fact that the sealing parts do not contact the entire surface on the inside. In particular, this also enables improved deformation elasticity of the sealing element when the door is closed.

The geometric specifications already explained above in this context as well as the exemplary embodiments explained below apply in particular when the door is arranged in the non-closed state. This means that the sealing element is arranged in its non-deformed basic state and is not deformed by the action of force that occurs when the sealing element rests on the front flange of the housing.

In one embodiment, the outer lining has a lateral edge area. Viewed in the horizontal section, this extends in the direction perpendicular to the width direction. This edge area thus extends in particular in the depth direction of the door. The edge strip forms the narrow side of the door. The edge strip has a multiple bending structure at its rear end, viewed in the depth direction. The multiple bending structure is in particular designed in a meandering manner. Through a Such an embodiment, the outer lining is particularly advantageously stabilized. In particular, it is correspondingly stiffened at least locally on this lateral edge area. In one embodiment, this multiple bending structure also makes it possible to stabilize an interface between the outer panel and the inner panel. Therefore, in this context, the interface between a lateral edge area of the inner paneling and the edge area of the outer paneling, in particular at the rear end of the edge area, is then also stabilized. This also makes it possible to correspondingly stabilize the adjacent arrangement of the sealing element.

In one exemplary embodiment, the multiple bending structure, viewed in this horizontal section, has a first partial structure that extends in the direction perpendicular to the width direction, in particular in the depth direction, and is designed at least as a double turn or double bend. In one exemplary embodiment, the multiple bending structure, viewed in this horizontal section, has a second partial structure that extends in the width direction and is designed at least as a double turn or double bend. The stability is correspondingly increased by this at least double-layer design of the partial structures. On the other hand, however, the number of turns is not so great that the weight would be unnecessarily increased and, in this respect, the dimensions would also be undesirably increased.

In one exemplary embodiment, the at least double windings are designed in such a way that the two winding layers are arranged at a distance from one another. In one exemplary embodiment, it can be provided that the first partial structure is exactly a double winding. Viewed in this horizontal section, it can have a U-like shape. In one embodiment, the second structure is a triple turn. In this horizontal section in particular, it can have an S-like shape.

In one exemplary embodiment, it is provided that the second partial structure is arranged so that it overlaps with the second wall part in the width direction. In this context, the overlap can be at least 50 percent of the length of this second partial structure measured in the width direction. In particular, it can be at least 60 percent, in particular at least 70 percent, in particular at least 80 percent, of this length measured in the width direction. In one embodiment, the first Substructure not or only slightly overlapping in this width direction arranged with the second wall part. In particular, viewed in this horizontal section, the first partial structure is arranged in the direction perpendicular to the width direction so that it overlaps with the second wall part.

Viewed in the horizontal section, the two partial structures can be arranged at an angle to one another which can be in particular between 70° and 100°, in particular between 80° and 100°. The partial structures are therefore formed in an L-like manner when viewed as a whole in this horizontal section, so that the multiple bending structure has this L-like shape when viewed as a whole.

In one exemplary embodiment, viewed in this horizontal section, an inner leg of the first partial structure, viewed in the direction perpendicular to the width direction, is formed with a length of between 5 mm and 9 mm, in particular between 6 mm and 8 mm. In this regard, this inner leg is designed to be relatively short. This makes it possible for the multiple bending structure, viewed in this horizontal section, to be arranged as far away as possible from a front part of the outer paneling in the direction perpendicular to the width direction. The fact that this multiple bending structure is shifted backwards in this regard also contributes to increasing stability. In addition, this embodiment also makes it possible for the multiple bending structure to be made relatively small in this horizontal section in the direction perpendicular to the width direction.

In one embodiment, the second partial structure abuts a front side of the second wall portion. In this context, the front side faces a front part or a front panel of the outer covering. Due to this concern, the partial structure is also used as a support structure or as a support part for the second wall part. This also means that the interface between the inner lining and the outer lining is significantly increased, at least locally.

In one exemplary embodiment, the second partial structure is designed as at least a 3-fold winding or 3-fold bend. In particular, it is only a 3-ply turn. In particular, it is shaped like an S in this horizontal section. In one exemplary embodiment, a distance measured in this horizontal section perpendicular to the width direction, in particular in the depth direction, between the front flexible leg of the second partial structure and an inside of a front panel of the outer covering is greater than 17 mm. This distance can preferably be greater than 19 mm and more preferably greater than 21 mm. This distance can preferably be in particular a maximum of 26 mm, preferably a maximum of 24 mm and more preferably a maximum of 22 mm. This specific spacing also advantageously contributes to the stabilization of the interface mentioned. In particular, as a result, the outer paneling is also stiffened when viewed in isolation.

In one embodiment, viewed in this horizontal section, the first partial structure extends further to the rear in the depth direction than the second wall part. The first partial structure therefore extends further rearward than the second wall part on the side facing away from the front panel of the outer covering.

In one exemplary embodiment, viewed in horizontal section, a transition between the first partial structure and the second partial structure is arranged at a depth measured in the depth direction, at which the second wall part is also arranged. The supporting effect and the stabilization that can be achieved with it at this interface are increased as a result. In particular, as a result, the second wall part can be attached in a more stabilized manner and is held in an improved manner.

In one embodiment, the sealing element is a multi-hollow chamber seal. This means that the sealing element has a plurality of hollow chambers that are separate and separate when viewed in isolation. These are each considered elastically deformable.

In one embodiment, the sealing element with hollow chamber areas is arranged outside of the anchoring receptacle. Viewed in particular in the horizontal section, this sealing element with these hollow chamber areas is designed to stand backwards over the anchoring receptacle. These hollow chamber areas are intended for direct contact with the front flange of the housing.

In one embodiment, viewed in this horizontal section, the sealing element has, on one side, several different contact points on the first wall part up. These are, in particular, a plurality of discrete contact points which are formed at a distance from one another. Viewed in the horizontal section, only the first contact point closest to the entrance in the width direction on this one side is offset by a maximum distance of 3 mm from the second contact point viewed in the horizontal section in the depth direction of the door. The distance is therefore also a value in an interval between the interval limits of +/- 5 mm.

Another independent aspect of the invention relates to a door for a household appliance. The door has an outer panel. In addition, the door has an inner lining that is separate from the outer lining. The interior lining has an anchoring seat for an anchoring body of a sealing element of the door. The sealing element of the door is anchored with this anchoring body in this anchoring receptacle. In a horizontal section of the door, the sealing member extends on both sides of the width of an entrance of the anchoring seat, viewed in the direction of the width of the door. The sealing element has a first sealing part which, in this width direction, extends to one side beyond the width of the entrance. The sealing member has a second sealing part which extends to the other side beyond the width of the entrance in this width direction. The interior paneling has a first wall part, which in this horizontal section, coming from this one side, ends at the entrance of the anchoring receptacle. The inner lining also has a second wall part, which in horizontal section, coming from this other side, ends on the one hand at the entrance and on the other hand ends at a free edge of the inner lining. The free edge is thereby formed by a free end of the second wall part. This is the end that faces away from the entrance. The width direction is therefore in particular the direction in the horizontal plane in which the clear width between the opposite boundary ends of the entrance is measured.

In a horizontal section, the first sealing part preferably abuts a first contact point on an inside of the first wall part and the second sealing part preferably abuts a second contact point on an inside of the second wall part in a horizontal section. Viewed here in this horizontal section, the first sealing part is then in contact with a first contact point on an inside of the first wall part. Viewed in this horizontal section, the second sealing part is preferably in contact with a second contact point on an inner side of the second wall part. In this horizontal section, these two contact points are offset from one another by a maximum distance of 5 mm in a direction perpendicular to this width direction, in particular in the depth direction of the door. They can therefore be arranged in the same or substantially the same position in this horizontal plane in this direction measured perpendicularly to the width direction.

Exemplary embodiments of the first independent aspect relating to the door are to be regarded as advantageous exemplary embodiments of the further independent aspect.

A further aspect of the invention also relates to a household appliance, in particular a household refrigeration appliance, with a door according to the aspect mentioned above or an advantageous configuration thereof.

The household refrigerating appliance can in particular be a refrigerator or a freezer or a fridge-freezer combination appliance and can therefore be designed for storing and preserving food.

The door can also form a closure element of a chest freezer, in which case the horizontal section is to be replaced by a vertical section and the depth direction of the door or of the closure element runs vertically.

The information “top”, “bottom”, “front”, “back”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction” are the intended use and intended arrangement of the door or the appliance given positions and orientations.

Further features of the invention result from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and/or shown alone in the figures can be used not only in the combination specified in each case, but also in other combinations or on its own, without departing from the scope of the invention. The invention is therefore also to be considered to include and disclose embodiments that are not explicitly shown and explained in the figures, but that result from the explained embodiments and can be generated by separate combinations of features. Versions and combinations of features are also to be regarded as disclosed which therefore do not have all the features of an originally formulated independent claim.

Exemplary embodiments of the invention are explained in more detail below with the aid of schematic drawings. Show it:

1 shows a perspective representation of an exemplary embodiment of a household appliance according to the invention;

2 shows a perspective sectional representation of a partial area of an exemplary embodiment of a door according to the invention; and

3 shows a partial area of a sectional view of the door according to FIG.

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

In Fig. 1 an embodiment of a household appliance according to the invention is shown in a perspective view. The household appliance is a household refrigeration appliance 1 here. It can be a refrigerator or a freezer or a fridge-freezer combination appliance. The household refrigeration appliance 1 is designed for storing and preserving food. The domestic refrigeration appliance 1 has a housing 2 . At least one receiving space for food is formed in the housing 2 . The receiving space can be a refrigerator compartment or a freezer compartment.

In one exemplary embodiment, the domestic refrigeration appliance 1 has a door 3 according to the invention. The door 3 is movably arranged on the housing 2 . It is arranged to close the receiving space at the front. The door 3 has a Outer panel 4 on. In addition, the door 3 has an interior lining 5 . The outer lining 4 is separate from the inner lining 5 . The outer panel 4 can be formed in one piece. The outer panel 4 can be made of metal, for example. The inner lining 5 is preferably designed in one piece. It can be made of plastic, for example. The outer lining 4 and the inner lining 5 delimit an intermediate space 6. Thermally insulating material is introduced into this intermediate space 6.

In addition, the door 3 has at least one sealing element 7 . The sealing element 7 is arranged on the rear side of the door 3 in the depth direction (z-direction). In this regard, the sealing element 7 is exposed at the rear. The relevant depth direction is also the depth direction of the household refrigeration appliance 1, in particular when the door 3 is closed.

This sealing element 7 rests against a front flange 8 of the housing 2 when the door 3 is in the closed state. The sealing element 7 is preferably designed to be completely circumferential.

In Fig. 2, the door 3 is shown in a partial area and shown in perspective in a horizontal sectional view. This horizontal section is formed in the x-z plane. This sectional plane is therefore spanned by the depth direction and the width direction (x-direction) of the door 3 . The thermally insulating material 9 can be seen here. As is also shown in FIG. 2 , the outer covering 4 has a front panel 10 . In addition, this outer lining 4 has an edge area 11 . This is the narrow side of the door 3. The edge area 11 extends to the rear and is directly adjacent to the front panel 10 at the side.

In Fig. 3, the view in horizontal section is shown in an enlarged representation, wherein the detail I in Fig. 2 is shown here. The sealing element 7 is unloaded here. This means that the door 3 is open and its sealing element 7 is not in contact with the front flange 8 . The inner lining 3 has an anchoring mount 12 . The anchoring receptacle 12 is designed like a blind hole in this horizontal section. In three dimensions, it is channel-shaped. The anchoring receptacle 12 is intended to receive an anchoring part 13 of the sealing element 7 . As can be seen, the anchoring part 13 is in the Anchoring recording 12 arranged anchored. The sealing element 7 also has several hollow chamber areas, only one of which is provided with the reference number 14 for the sake of clarity. In the horizontal section, these hollow chamber areas 14 are arranged outside of the anchoring receptacle 12 in a direction perpendicular to the width direction (x-direction) and are arranged on the side facing away from the front panel 10 in this regard. The direction perpendicular to the width direction in the horizontal section is the depth direction here.

The sealing element 7 is designed here as a multiple hollow chamber seal. As can also be seen in FIG. 3 , this anchoring receptacle 12 has an entrance 15 . This entrance 15 has a width b in the width direction. The sealing element 7 has a first sealing part 16 . This first sealing part 16 extends in this width direction to one side beyond the width of the entrance 15 . This means that it also extends laterally to this entrance 15 in this width direction. The sealing element 7 also has at least one second sealing part 17 . Viewed in this horizontal section, this second sealing part 17 extends to the other side beyond the width of the entrance 15 in this width direction. As can be seen in FIG. 3, in this horizontal section the first sealing part 16 extends on the left beyond the dimensions of the inlet 15 and the second sealing part 17 in this horizontal section extends beyond the dimensions of the inlet 15 on the right.

The interior lining 5 has a first wall area or a first wall part 18 . Coming from this one side, this ends at the entrance 15 in the horizontal section shown. In particular, this first wall part 18 ends at a first entrance edge 19 of the entrance 15 . The second wall part 20 ends in this horizontal section according to FIG. 3 coming from the other side at the entrance 15 . The second wall part 20 has an end facing away from the entrance 15 , especially viewed in this horizontal section. The end is freely cantilevered. In one embodiment, it forms a peripheral edge 20a of the inner lining 5.

In particular, it ends at an entry edge 21 of the entry 15. As can also be seen in FIG. 3, the first sealing part 16 lies locally on an inner side 22 of the first Wall part 18 on. In this regard, it rests against a first bearing point 23 on this inner side 22 . In contrast, the second sealing part 17 rests against an inner side 24 of the second wall part 20 . In particular, in this regard, it is also only locally in contact with a contact point 25 on this inner side 24 . It is provided in particular that the first contact point 23 and the second contact point 25 viewed in this horizontal section in the direction perpendicular to the width direction, and thus in particular in the depth direction, are offset from one another by a maximum distance d. This distance d is less than or equal to 5 mm. In one exemplary embodiment, the distance d can refer to the distance that, viewed in the depth direction, relates to the two closest contact points on the one hand of the first sealing part 16 on the inside 22 and on the other hand of the second sealing element 17 on the inside 24.

In one exemplary embodiment, the second contact point 25 formed on the second wall part 20 is arranged a maximum of 5 mm closer to an inner side 33 of the front panel 10 of the outer paneling 4 than the first contact point 23, viewed in horizontal section in the depth direction of the door 3.

As can also be seen in Fig. 3, in this horizontal section viewed in the width direction, the first contact point 23 is closer to the entrance 15 than the second contact point 25. In this horizontal sectional view, the second contact point 25 is closer to the edge region 11 than the first Investment point 23.

In addition, it can also be seen that the second wall part 20 is designed in a straight line when viewed in this horizontal section. It extends in the width direction. Viewed in the depth direction, this second wall part 20 is arranged in particular at the depth of the entrance 15 . In particular, this is provided over its entire length in this horizontal section. In one exemplary embodiment, the wall part 20 thus preferably extends perpendicular to the orientation of the edge region 11.

Viewed in this horizontal section, the second wall part 20 is configured in a straight line, in particular completely in a straight line.

As can also be seen, the surface of the first sealing part 16 facing the first wall part 18 is not in contact with it over its entire surface, but only in one area thereto reduced surface area adjacent thereto. This surface area then also represents the directly touching contact surface. In this respect, the contact point 23 is then to be understood in particular. In particular, the first sealing part 16 is arranged without contact with the inside 22 when viewed on a surface area which is closer to the entrance 15 than the contact point 23 .

In one exemplary embodiment, the outside of the second sealing part 17 , which faces the second wall part 20 , is also only locally in contact with the inside 24 . As can be seen in FIG. 3, here too the second sealing part 17 is arranged without contact with the inside 24 over a larger surface area. The outside of the second sealing part 17 only bears directly against the inside 24 with an outer surface area that is outer in this respect and represents a contact surface. The second contact point 25 is then formed with this outer surface area or the contact surface.

In one exemplary embodiment, the edge region 11 has a multiple bending structure 27 at a rear end 26 viewed in the horizontal section in the depth direction. The multiple bending structure 27 is designed here in particular in a meandering manner. The multiple bending structure 27 has, viewed in the horizontal section shown in FIG. 3 , a first partial structure 28 which extends in the depth direction and is designed at least as a double winding. In one exemplary embodiment, the multiple bending structure 27 has a second partial structure 29 that extends in the width direction, viewed in this horizontal section, and is designed at least as a double winding. In the exemplary embodiment, the first partial structure is designed only as a double turn. In the exemplary embodiment, the second partial structure 29 is designed as a triple winding, in particular as an S-shaped winding. The first substructure 28 has an inner leg 30 . This inner leg 30 has a length 11 viewed in the horizontal section in the depth direction. This length 11 is preferably between 5 mm and 9 mm, preferably between 6 mm and 8 mm.

As can also be seen in FIG. 3, the two legs of this double turn of the first partial structure 28 are arranged at a distance from one another. In one exemplary embodiment, the second partial structure 29 is arranged in abutting manner on an outer side 31 of the second wall part 20 . In particular, a large-scale system is provided here. In one exemplary embodiment, the second partial structure 29 also serves as a support structure for the inner lining 5, in particular for the second wall part 20. It is therefore this interface at which the inner lining 5 and the outer lining 4 are appropriately reinforced and supported, making direct contact here. A peripheral area around this interface, in particular also the area of the inner lining 3 which accommodates the sealing element 7, is thus also additionally supported and stiffened.

The multiple bending structure 27 is particularly advantageous since the outer covering 4, in particular the edge area 11, is thus also reinforced.

In one embodiment, the second partial structure 29 has a front flexible leg 32 . In the horizontal section, this is the flexible leg that is closest to the front panel 10 of the outer paneling 4 in the depth direction. In one exemplary embodiment, a distance I2 between the inside 33 of the front panel 10 of the outer paneling 4 and this nearest flexible leg 32 is 21.5 mm. The distance I2 can particularly preferably be greater than 17 mm, preferably greater than 19 mm and more preferably greater than 21 mm. The distance I2 can particularly preferably be a maximum of 26 mm, preferably a maximum of 24 mm and more preferably a maximum of 22 mm. Viewed in the horizontal section, a transition 34 between the first partial structure 28 and the second partial structure 29 is arranged at a depth measured in the depth direction, at which the second wall part 20 is also arranged.

As is also shown in the exemplary embodiment, the sealing element 7 has a plurality of separate contact points 23 and 35 on one side in horizontal section. In this regard, the sealing element 7 has a further sealing part 36 which is separate from the first sealing part 16 . The relevant further contact point 35 of this further sealing part 36 on the inside of the interior lining 3 is at a distance from the contact point 23. Viewed in the width direction, in this horizontal section the distance d is only between that contact point and thus also that sealing part 16 in relation to the second sealing part 25 to put the other side in relation or to see in comparison, which is the entrance 15 in this width direction closest. In this regard, this further contact point 35 is further away from the entrance 15 in this width direction than this first contact point 23. This further contact point 35 on this one side is therefore irrelevant with regard to the distance d and is not to be seen in relation to the second contact point 25 in this regard.

As is also shown in Fig. 3, the anchoring receptacle 12 extends closer to the inner side 33 than the second partial structure 29 in this horizontal section, viewed in the depth direction.

In general, it can also be said that the outer paneling 4 has improved rigidity overall. This is achieved in particular by the multiple bending structure 27 and its position at the rear end 26 . In particular, due to the compactness of this multiple bending structure 27 formed in the depth direction and its specific spacing, in particular with the distance I2, contributes to this rigidity. This also ensures that this multiple bending structure 27 is as far away as possible from the center of mass M of the outer paneling 4 to the rear. In addition, the interior paneling 5 can be designed very simply due to the specific shape of the second wall part 20, starting from the anchoring receptacle 12 in the width direction outwards towards the edge area 11 and in this regard can also be formed without a height offset. This has particular advantages when producing the inner lining 5, in particular when this is produced by thermoforming. In addition, this orientation of the second wall part 20 allows the sealing element 7 to be designed more simply, in particular on that side in the horizontal section on which this second wall part 20 also extends. With the stroke remaining the same, this sealing element 7 can be made more compact.

In general, it is also achieved that an improved filling of the intermediate space 6, in particular with insulating foam, is made possible. This is because there are fewer constrictions or undercuts and thus niches in this intermediate space 6 that would have to be filled. Reference List
