Description

Domestic appliance door and method for assembling a domestic appliance door

Technical Field

The invention relates to a household appliance door and a method for assembling a household appliance door.

Background

DE 102010027918 a1 discloses a door for a domestic appliance, which has a door closing element, which, during assembly, is first moved obliquely into a front edge (Umbug) of the door leaf and is then fastened by a pivoting movement in the main direction of extension of the door leaf to the two side walls of the door leaf by in each case one latching connection. In the assembled state, there is no protrusion of the door closing element beyond the door panel. In order to seal the side walls to prevent the insulating foam from escaping during foaming of the household appliance door, an additional sealing element must be used.

Disclosure of Invention

The object of the invention is, in particular, to provide a device of this type with improved properties with regard to tolerance balancing and simple assembly.

The invention is based on a domestic appliance door, in particular a domestic refrigerator door, having at least one outer wall with at least one front wall element and at least one side wall element, which has at least one plug element on at least one edge region, and having at least one door closing element, which has at least one mating plug element in at least one further edge region, which mating plug element cooperates with the plug element in at least one assembled state for producing a common plug connection.

It is proposed that the mating plug element has a plug direction which extends at least substantially perpendicularly to the main extension plane of the side wall element. This advantageously enables a simple assembly of the door closing element. Advantageously, the front wall element can provide a guide for the door closing element upon assembly of the household appliance door. This makes it possible to achieve a low error rate in particular when fitting the household appliance door. Advantageously, the plug element and/or the mating plug element can have at least one groove and/or at least one rib and/or at least one bead, as a result of which an additional sealing element for sealing a side wall of the household appliance door can be dispensed with and the door closing element can be prevented from protruding laterally beyond the outer wall.

A "domestic appliance", in particular a "domestic refrigeration appliance", is to be understood to mean, in particular, an electric, alternatively and/or additionally gas-operated and/or oil-operated appliance, which is provided for domestic use, in particular for completing and/or assisting a household, advantageously a cooking process and/or a cleaning process and/or a cooling process, and/or which is provided for preserving food, in particular under controlled conditions. In particular, it is advantageous if the domestic appliance, which is designed as a domestic refrigerator, is provided for cooling refrigerated goods, in particular food products such as beverages, meat, fish, milk and/or milk products, in at least one operating state, in particular in order to achieve a longer durability of the cooled goods. The domestic appliance configured as a domestic refrigeration appliance can in particular have a wine storage tank, a refrigerated cabinet and advantageously a refrigerator and/or freezer. Alternatively, the household appliance can be configured in particular as a household cleaning appliance, for example as a washing machine and/or as a rinsing machine and/or as a drying machine and/or as a household cooking appliance, for example as an oven and/or as an oven. The "main plane of extension" of the structural unit is to be understood in particular as the following plane: the plane extends parallel to the largest side of the smallest imaginary right-angled parallelepiped which surrounds the structural unit exactly also completely and in particular passes through the center point of the right-angled parallelepiped.

"outer wall" is to be understood in particular as the following element: the unit at least largely defines the outer contour of the door of the domestic appliance in the assembled state. In this case, "at least a majority" is to be understood in particular as meaning at least 60%, advantageously at least 70%, particularly advantageously at least 80%, preferably at least 90% and particularly preferably completely. In particular, the outer wall can comprise at least one plastic-based and/or metal-based material. Preferably, the outer wall has at least one door panel. Advantageously, the outer wall has a front wall element which at least largely delimits the at least one domestic appliance door front wall in the assembled state. Particularly advantageously, the outer wall has at least one side wall element which, in the assembled state, at least largely delimits at least one household appliance door side wall. In an advantageous embodiment, the side wall element is formed integrally with the front wall element. Alternatively, the side wall element and the front wall element can be constructed separately from one another. In particular, in the assembled state, at least one rear wall element is assembled on the outer wall, which rear wall element in particular at least largely delimits the rear wall of the domestic appliance door. In particular, in the assembled state, at least one wall element of the domestic appliance door can be assembled on the outer wall, which wall element at least partially delimits the outer domestic appliance door. In this case, "at least partially" is to be understood to mean, in particular, at least 20%, preferably at least 40%, particularly preferably at least 60%, advantageously at least 80%, and particularly advantageously completely. For example, the wall element can have at least one gate stack (trogarnitur). In particular, the outer wall defines in the assembled state at least one inner chamber which is at least largely filled with at least one insulating material, preferably an insulating foam, in the assembled state of the household appliance door.

An "edge region of an object" is to be understood to mean, in particular, a partial region of the object which, in the main direction of extent of the object, has a distance of at most 15%, advantageously at most 12%, particularly advantageously at most 10%, preferably at most 7%, and particularly preferably at most 5% to an outer boundary of the object. The "main direction of extension" of the object is to be understood in particular as the following direction: said direction extends parallel to the longest edge of the smallest geometrical rectangular parallelepiped which just completely surrounds the object as well. Advantageously, the edge region of the side wall element is different from the following connection region: the connecting region comprises at least one contact surface and/or at least one transition region shared by the front wall element and the side wall element.

"plug element" is to be understood to mean in particular the following elements: the element is provided for forming at least one form-fitting plug connection with at least one mating plug element in the assembled state of the plug element. The term "plugging direction" is to be understood in particular to mean the following direction: along this direction, a plug connection can be established in particular. In particular, for the purpose of establishing a plug connection, the mating plug element can be moved, in particular moved, relative to the plug element along a plug direction, in particular starting from a predefined position. Alternatively or additionally, for example for establishing a plug connection, the plug element can be moved, in particular moved, relative to the mating plug element along a plug direction, in particular starting from a predefined position. The plug element has an elongated hole and, in the assembled state, engages with a mating plug element having a rod-shaped plug, for example, the plugging direction of which is parallel to the main extension direction of the rod-shaped plug and extends, as viewed from the plug, in the direction of the plug element. In particular, the plug element and the mating plug element each have at least one form-locking element. For example, the plug element and/or the mating plug element for mating can each have at least one latching element and/or groove and/or rib and/or bead and/or hook and/or detent. Advantageously, the front wall element has at least one further plug element, which is provided in particular for guiding the door closing element when the plug connection is formed. Preferably, the outer wall has at least two side wall elements, which each have at least one plug element on at least one edge region. Particularly preferably, the door closing element has at least two mating plug elements, which are arranged in particular on opposite edge regions of the door closing element. In particular, the door closing element can have a further mating plug element which is arranged on an edge region of the door closing element facing the front wall element in the assembled state.

In particular, the term "mated" of the mating plug element with the plug element in the assembled state is to be understood to mean that the mating plug element and the plug element form at least one common form fit in the assembled state.

"door closing element" is to be understood in particular as the following element: the elements largely define the upper side of the domestic appliance door and/or the lower side of the domestic appliance door in the assembled state. Advantageously, the domestic appliance door has at least two door closing elements. Advantageously, in the assembled state, one of the door closing elements largely defines an upper side of the household appliance door and the other of the door closing elements largely defines a lower side of the household appliance door. In particular, the two door closing elements can be configured identically to one another. Preferably, the door closing elements are configured differently from each other. For example, the individual elements can be present in only one of the door closing elements.

The term "substantially perpendicular" is intended here to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction (in particular viewed in a plane) enclose an angle of 90 ° and the angle has a maximum deviation of, in particular, less than 8 °, advantageously less than 5 °, and particularly advantageously less than 2 °.

"edge covering" is to be understood in particular as meaning a partial region of the preferably plate-shaped object which occurs as a result of the object being bent at an angle of at least substantially 90 ° at a transition region which connects the partial region to the remaining object. In this case, "at least substantially" is to be understood in particular to mean that the deviation from the predefined value differs in particular by less than 25%, preferably less than 10% and particularly preferably less than 5% of the predefined value.

"provided" is to be understood in particular to mean designed and/or configured in particular. "an object is provided for a specific function" is to be understood in particular as meaning: the object performs and/or implements the determined function in at least one application state and/or operating state.

Furthermore, it is proposed that the mating plug element and the plug element, in the assembled state, delimit and/or prevent a movement of the door closing element relative to the side wall element at least substantially parallel to a main plane of extension of the side wall element. The term "at least substantially parallel" is intended here to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction (in particular viewed in a plane) enclose an angle of 0 ° and the angle has a maximum deviation of, in particular, less than 8 °, advantageously less than 5 °, and particularly advantageously less than 2 °. In particular, a good retention of the door closing element in the assembled state can thereby be achieved. Advantageously, it is possible to avoid the door closing element slipping out during and/or after assembly.

It is furthermore proposed that the door closing element has at least one mating latching element opposite the mating plug element, which mating latching element cooperates with at least one latching element of the outer wall opposite the plug element in the assembled state. Advantageously, the counterpart catch element is arranged on a further edge region of the door closing element, which is opposite to the edge region of the door closing element. In particular, the retaining element is part of a further side wall element of the outer wall. Preferably, the further side wall elements and the side wall elements are arranged on mutually opposite edge regions of the outer wall with respect to the transverse extension direction of the outer wall. The term "transverse direction of extension" of an object is to be understood in particular as meaning the following direction: said direction being oriented perpendicular to the main extension direction of the object and perpendicular to the thickness of the object. The "thickness" of the object is to be understood in particular as the following extension: the extension is oriented parallel to the shortest side of the smallest imaginary geometrical rectangular parallelepiped which just completely encloses the object as well. In particular, the lateral extension direction is oriented parallel to a main extension plane of the object. An "extension" of an object is to be understood in particular as the maximum distance between two points of a perpendicular projection of the object onto a plane. In particular, the clip element is preferably arranged on a further edge region of the further side wall element, which in particular has the same extent as the edge region of the side wall element. "clamping element" is to be understood to mean in particular the following elements: the element cooperates with at least one mating clip element in the assembled state for forming a common clip connection. "snap-in connection" is to be understood in particular as the following connection: the connection is formed by at least one deformation of the snap-in element and/or the mating snap-in element, a relative movement of the snap-in element with respect to the mating snap-in element and/or a relative movement of the mating snap-in element with respect to the snap-in element, and a return forming (rickformung) of at least the snap-in element and/or the mating snap-in element. "deformation of the object" is to be understood in particular as the following process: the process comprises at least one change in the shape and/or volume of the object. Preferably, the deformation is a reversible process. For example, the deformation can comprise at least one bending process and/or at least one melting process and/or at least one tensioning process and/or at least one pressing process and/or at least one stretching process. Preferably, the door closing element and/or the further side wall element has at least one latching region in which a mating latching element and/or a latching element is arranged and which, by means of at least one deformation, effects a mating of the mating latching element and the latching element. Particularly preferably, the deformation is such that the mating trim element and the trim element can form a common form closure by a relative movement. "recovery molding of an object" is to be understood in particular as the following process: the process follows at least one deformation of the object and reverses the at least one deformation of the object. In particular, a bayonet connection is distinguished from a plug connection. In particular, the snap-fit connection is different from the following connections: the connection is formed by the cooperation of at least two objects in the assembled state and only requires movement of one of the objects relative to the other of the objects for forming. In particular, this enables simpler tolerance balancing of the household appliance door. Advantageously, the snap-in connection can ensure the retention of the door closing element in the assembled state, in particular independently of differences in the extension of the door closing element and/or the outer wall. It is particularly advantageous to be able to provide a simple and/or inexpensive door for a domestic appliance. In particular, additional components for tolerance compensation can be omitted.

It is furthermore proposed that the plug element has a much greater extent than the retaining element in at least one direction oriented at least substantially perpendicularly to the main plane of extension of the side wall element. In this case, the expression that the first extension is "much larger" than the second extension is to be understood in particular to mean that the first extension is at least 130%, advantageously at least 140%, particularly advantageously at least 150%, preferably at least 160% and particularly preferably at least 170% of the second extension. Preferably, the outer wall has a plurality of plug elements, at least one of which has a much greater extent than the retaining element in at least one direction oriented at least substantially perpendicularly to the main plane of extension of the side wall element. This enables a simple assembly of the household appliance door in particular. In particular, the plug element can be slightly different from the retaining element, as a result of which a low error rate during assembly can advantageously be achieved. Particularly advantageously, a sealing action of the plug element can be achieved. In particular, a large contact surface of the plug element on the mating plug element can be provided in the assembled state.

It is furthermore proposed that the outer wall has at least one recess which is provided for receiving at least one handle element and which is at least partially defined by the front wall element. The expression that the recess is "at least partially" defined by the front wall element should be understood in particular to mean that the recess is defined by at least 20%, advantageously at least 35%, particularly advantageously at least 50%, preferably at least 65% and particularly preferably at least 80% by the front wall element. A "recess" of an object is to be understood to mean, in particular, a hole and/or an opening and/or a depression of the object. The recess is in particular at least partially surrounded by the surface of the object and is in particular free of material of the object. For example, the recess can have a hole and/or an opening and/or a depression. The recess is defined in particular by a partial region of the object. The handle element preferably has at least one form-locking element in at least one edge region, which in particular at least delimits the contact surface of the handle element on the outer wall, which form-locking element cooperates with a further form-locking element of the front wall element in the assembled state for forming a common form-locking. The form-locking element and the further form-locking element can have, for example, a latching element and/or a screw element and/or a plug element. Advantageously, the grip element has at least one, in particular concave, grip surface which is arranged, in particular completely, inside a shell which is as small as possible concave and which comprises precisely the front wall. The recess, in particular in at least one transverse direction of extension of the front wall element, can advantageously be arranged on an edge region of the front wall element. Advantageously, the extension of the recess parallel to the main extension direction of the front wall element will be at least substantially the same as the extension of the front wall element along its main extension direction. "at least substantially identical" is to be understood in particular to mean identical, taking into account at least one manufacturing tolerance. This advantageously enables an efficient use of installation space. In particular, the projecting grip element can be dispensed with.

Advantageously, the groove is at least partially defined by a further side wall element of the outer wall. In particular, the recess extends over at least a partial region of the outer wall, which partial region connects the front wall element to the further side wall element. The partial region can, for example, have a rim of an outer wall. The handle element preferably has at least one form-locking element in at least one edge region, which form-locking element cooperates in the assembled state with the further form-locking element of the front wall element and with the further form-locking element of the further side wall element for forming a common form-locking. This advantageously enables an efficient use of installation space. In particular, in the case of a domestic appliance door in a french door domestic appliance, a small distance between the two domestic appliance doors can be achieved. In particular, good sealing and/or isolation of the household appliance door can be achieved in the case of a household appliance door used in a french door household appliance. Advantageously, a small extension of the tilting beam of the french door household appliance can be achieved.

In particular, the door closing element has at least one supporting element which, in the assembled state, provides reinforcement of the side wall element and at least partially defines the sealing element. The support element can be mounted in particular in the mounted state on the base body of the door closing element. For example, the support element can be mounted on the base body of the door closing element in the mounted state by means of a snap-in connection and/or a plug-in connection and/or a screw connection and/or an adhesive connection. "stiffening of the side wall element" is to be understood in particular to mean a form-locking of at least one partial region of the side wall element and/or of at least one element with at least one partial region of the door closure element and/or of at least one element, which form-locking increases the tension of the side wall element in the assembled state. The reinforcement is preferably provided for reducing the deformation of the side wall element when a pressure force, in particular a pressure force acting perpendicular to the main extension plane of the side wall element, acts. The expression "at least partially" defining a sealing element should be understood in particular to mean that the sealing element is defined by the support element alone or together with at least one further element, for example with the side wall element and/or with the plug element of the side wall element. In particular, deformation of the side wall elements can thereby be avoided. Advantageously, the sealing material can be prevented from spilling during foaming of the door of the household appliance. In particular, the support element can be provided for narrowing and/or lengthening at least one channel of at least one sealing material, in particular like a conventional labyrinth seal, in order to prevent the sealing material from escaping via said channel.

Preferably, the support element is formed integrally with at least one base body of the door closing element. The term "substrate of an object" is to be understood in particular as the following element: the elements define and/or form a mass fraction and/or a volume fraction of the object of at least 60%, advantageously at least 70%, particularly advantageously at least 80%, preferably at least 90% and particularly preferably 100%. The base body of the door closing element is preferably plate-shaped. A plate-shaped object is to be understood to mean in particular the following object: the object has a thickness which corresponds to a maximum of 20%, in particular a maximum of 15%, advantageously a maximum of 10%, preferably a maximum of 5%, of a second small extent (in particular the length and/or the width) of the smallest possible right-angled parallelepiped which also receives the object. Preferably, the object has at least one, preferably at least two, in particular mutually opposite sides, which have a flat, in particular smooth surface. The support element can in particular have a projection, preferably a rib, of the base body. This enables a simple assembly of the household appliance door in particular. In particular, an additional assembly step for assembling the support element is dispensed with.

It is further proposed that the door closing element has at least one partial region which is provided for receiving at least one electronic functional unit. In at least one operating state, the electronic functional unit is arranged, in particular, at least largely and advantageously completely within the partial region. An "electronic functional unit" is to be understood in particular as the following unit: the unit is provided for providing at least one predefined function by using electrical energy in at least one operating state. For example, the electronic functional unit can have at least one optical and/or thermal and/or tactile and/or audible sensor. Preferably, the electronic functional unit has at least one moisture sensor. In particular, the partial region defines at least one recess of the door closing element. Advantageously, the partial region is arranged on the side of the door closing element facing away from the interior chamber in the fitted state. Alternatively, the partial region can be arranged on the side of the door closing element which faces the interior in the fitted state. This enables particularly effective use of installation space. Advantageously, a small space requirement of the electronic functional unit can be achieved in particular. In a particularly advantageous manner, the door closing element can be used as a covering device for the electronic functional unit, whereby additional components for protecting the electronic functional unit are dispensed with.

A particularly simple assembly can be achieved in particular by a method for assembling a household appliance door having at least one outer wall with at least one front wall element and at least one side wall element with at least one plug element on at least one edge region, and having at least one mating plug element in at least one further edge region. Advantageously, in order to mate the plug element with a counterpart plug element, in at least one assembly step the door closing element is moved relative to the side wall element along a plugging direction extending at least substantially perpendicularly to the main extension plane of the side wall element. The door closing element is preferably guided in its movement on at least one further plug element of the front wall element. In particular, it is conceivable to orient the door closing element in the assembly step such that a main extension direction of the door closing element is oriented at least substantially perpendicularly to a main extension plane of the side wall element. Preferably, in the assembly step, the door closing element is oriented such that the main extension direction of the door closing element is oriented at least substantially perpendicularly to the main extension plane of the side wall element and is separated from the main extension plane of the side wall element by a minimum angle of at least 10 °, in particular at least 15 °, advantageously at least 20 °, particularly advantageously at least 30 °, preferably at least 35 ° and particularly preferably at least 40 °. This advantageously enables a simple assembly of the door closing element. The guidance of the door closing element on the further plug element of the front wall element advantageously prevents the door closing element from slipping off during the assembly step. This makes it possible in particular to achieve a low error rate when forming a plug connection. Advantageously, the plug element and/or the mating plug element can have at least one groove and/or at least one bead, thereby eliminating an additional sealing element for sealing a side wall of the household appliance door.

In particular, it is conceivable that, in at least one further assembly step following the assembly step, the door closing element is moved relative to the side wall element along an insertion direction which extends at least substantially perpendicularly to the main extension plane of the side wall element. In particular, the further mating plug element is partially plugged onto the plug element of the front wall element. Preferably, in at least one further assembly step following the assembly step, in particular in order to mate a counterpart catch element of the door closing element with a catch element of a further side wall element of the outer wall, the door closing element is moved relative to the side wall element along a swing direction extending at least substantially perpendicularly to the main extension plane of the front wall element. The term "moving the door closing element in a pivoting direction" is to be understood in particular to mean rotating the door closing element about an axis of rotation defined by the plug connection, wherein the pivoting direction defines the direction of rotation of the door closing element. In particular, the cooperation of the plug element with the counterpart plug element can be used to define the axis of rotation of the door closing element. This enables a simple assembly of the door closing element in particular. In particular, a further mating plug element of the door closing element and a further plug element of the front wall unit can gradually form a further plug connection during a further assembly step by a pivoting movement of the door closing element, in contrast to a translational movement of the door closing element in the same direction. Advantageously, a low error rate can be achieved when forming the further plug connection.

It is furthermore proposed that the at least one further side wall element and/or the door closing element of the outer wall is/are at least partially elastically deformed, in particular elastically bent, relative to the front wall element in a direction oriented at least substantially parallel to the main plane of extension of the front wall element in the further assembly step. The term "at least partially" elastically deformed by the element in the further assembly step is to be understood in particular to mean that at least one first partial region of the element is elastically deformed in the method step relative to at least one second partial region of the element, which is arranged differently from the first partial region and in particular at a distance from the first partial region. For example, the second subregion of the element can have an extension of at most 90%, advantageously at most 70%, particularly advantageously at most 50%, preferably at most 30% and particularly preferably at most 10% of the maximum extension of the element. In the further assembly step, the first partial region can be deformed elastically relative to the second partial region, in particular by means of a rotational movement and/or by means of a torsional movement. In particular, the element is provided for exerting a force in the absence of an external force into the rest position and in particular for taking up the rest position. In particular, a simple tolerance compensation of the household appliance door can thereby be achieved. Advantageously, the snap-in connection can be formed independently of tolerance differences of the outer wall and/or the door closing element. In addition, a cost-effective design of the domestic appliance door can be realized in particular. In particular, it is advantageously possible to dispense with additional components for tolerance compensation of the household appliance door.

Here, the household appliance door should not be limited to the applications and embodiments described above. In particular, a household appliance door for carrying out the functional principle described here can have a number which is different from the number mentioned here of the individual elements, components and units.

The recess 44 extends over the connecting region 68 of the further side wall element 60 and the front wall element 16.

The door closing element 30 has a plurality of

support elements

48, 50, 52. The

support elements

48, 50, 52 are shown in detail in fig. 7. In the following, the singular is used in terms of the same characteristics of the

support elements

48, 50, 52. The

support elements

48, 50, 52 have a projection of the door closing element. The

support elements

48, 50, 52 are formed integrally with the base body of the door closure element. The

support elements

48, 50, 52 provide reinforcement of the sidewall element 18. The

support elements

48, 50, 52 provide support for the plug element 22. The

support elements

48, 50, 52 define sealing elements. The

support elements

48, 50, 52 prevent, like labyrinth seals, the escape of material between the side wall element 18 and the door closing element 30.

The door closing element 30 has a partial region 54. This part-area 54 is shown in detail in fig. 3. The partial region 54 has a depression of the door closing element 30. The part area 54 is provided for receiving an electronic functional unit (not shown). The electronic functional unit has a humidity sensor. Alternatively, the electronic functional unit can have further conventional sensors and/or transmission units and/or control units.

Fig. 8 shows a schematic flow diagram of the assembly of the household appliance door 12. In a first assembly step 100, the door closing element 30 is oriented with respect to the outer wall 14. The main extension direction (not shown) of the door closing element is oriented perpendicular to the main extension plane of the side wall element 18 during the first assembly step 100. The main extension direction of the door closing element 30 is oriented during the first assembly step 100 such that it is diverging at an angle of substantially 25 ° from the main extension plane of the side wall element 18. The further plug element 70 of the front wall element 16 partially cooperates with a further counterpart plug element 72 of the door closing element 30. The cooperation of the further plug element 70 with the further mating plug element 72 participates in the orientation and guidance of the door closing element 30.

In a second assembly step 110, the door closing element 30 is moved relative to the side wall element 18 for mating the

plug elements

22, 24, 26, 28 with the

mating plug elements

34, 36. The door closing element 30 is moved in a plugging direction 38 which extends perpendicularly to the main extension plane of the side wall element 18. Here, the second assembly step 110 follows the first assembly step 100.

In a third assembly step 120, the further side wall element 60 of the outer wall 14 is deformed, in particular bent, elastically relative to the front wall element 16 in part in a direction 62 oriented at least substantially parallel to the main plane of extension of the front wall element 16. In a third assembly step 120, further edge region 56 is moved relative to the rest of side wall element 60 in a direction perpendicular to the main plane of extension of further side wall element 60. Alternatively, in a third assembly step 120, the door closing element 30 can be moved relative to the rest of the door closing element 30, in part by means of a twisting movement of the further edge region 80 of the door closing element 30. The door closing element 30 is then moved relative to the side wall element 18. The door closing element 30 is moved in a swinging direction extending perpendicularly to the main extension plane of the front wall element 16. The door closing element 30 executes an oscillating movement 58. The cooperation of the

plug elements

22, 24, 26, 28 with the

mating plug elements

34, 36 defines an axis of rotation of the pivoting movement 58 of the door closing element 30, which is oriented parallel to the main direction of extension 78 of the side wall element 18. The engagement of the further plug element 70 with the further mating plug element 72 is effected by the pivoting movement 58 of the door closing element 30. Here, the third assembly step 120 follows the second assembly step 110.

In a fourth assembly step 130, a return forming of the further side wall element 60 is carried out. The snap-in element 42 is guided by the opening 64 during the return forming. The return forming produces the engagement of the catch elements 42 of the side wall element 60 with the mating catch elements 40 of the door closing element 30.
