DETAILED DESCRIPTION OF THE INVENTION

[0047] In the figures, identical or functionally identical elements are provided with the same reference characters.

[0048] With indications of “top,” “bottom,” “front,” “rear,” “horizontal,” “vertical,” “depth direction,” “width direction,” “height direction,” etc., the positions and orientations given in intended use and intended configuration of the apparatus are specified.

[0049] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a household refrigeration apparatus 1 shown in a simplified representation, which is provided for storing and preserving food. The household refrigeration apparatus 1 includes a housing 2. The housing 2 includes an exterior housing 3. Moreover, the household refrigeration apparatus 1 includes an interior container 4 separate from the exterior housing 3. The interior container 4 is received in the exterior housing 3. A thermally insulating material such as for example insulating foam and/or a vacuum insulating panel is disposed in a clearance 5 between the exterior housing 3 and the interior container 4.

[0050] In the embodiment, the interior container 4 bounds a receiving space 6 with its walls, which is formed for receiving food. Here, the receiving space 6 is in particular formed as a refrigerating compartment.

[0051] On the front side, the interior container 4 includes a loading opening, via which food can be taken into or be removed from the receiving space 6. In the embodiment, the receiving space 6 is closable by two separate doors 7 and 8. The two doors 7 and 8 are pivotably disposed at the housing 2. The two doors 7 and 8 are disposed in the same height position viewed in height direction (y-direction) of the household refrigeration apparatus 1. In width direction (x-direction) of the household refrigeration apparatus 1, they are disposed next to each other such that they collectively close the receiving space 6 on the front side in the closed state. In particular, these two doors 7 and 8 are disposed in a common plane in the closed state, which is spanned by the height direction and the width direction.

[0052] In FIG. 1, the door 7 on the left side with front-side view is illustrated opened and the door 8 on the right side is illustrated closed.

[0053] The household refrigeration apparatus 1 includes at least one further receiving space 9 for food. This further receiving space 9 is separated from the first receiving space 6. The further receiving space 9 can for example be a freezing compartment or a keep-fresh compartment or a further refrigerating compartment. Viewed in height direction, this further receiving space 9 is formed below the first receiving space 6. The further receiving space 9 is in particular bounded by further walls of an interior container, which can also be the interior container 4. Preferably, it is provided that the further receiving space 9 is bounded by a further door 10, which is shown in the closed state in FIG. 1. Preferably, it is provided that this door 10 is formed as a front plate of a drawer linearly retractable and extendable in depth direction (z-direction) of the household refrigeration apparatus 1.

[0054] It can be provided that the household refrigeration apparatus 1 includes multiple, separate further receiving spaces 9, and further such explained drawers are preferably formed in this context. They can adjoin to the further receiving space 9 towards the bottom viewed in height direction. They are in particular also formed within the housing 2.

[0055] Further, the door 10, in particular this front plate, is disposed in the same plane as the doors 7 and 8 in the closed state of the doors 7, 8 and 10. In particular, the doors 7, 8 and 10 are front-side vision components of the household refrigeration apparatus 1. In particular, they are also, if they are closed, disposed without overlap with each other.

[0056] Moreover, the household refrigeration apparatus 1 includes an ice maker 11. The ice maker 11 occupies a partial area of the volume of the receiving space 6 and is thermally insulated from the remaining volume of the receiving space 6. The ice maker 11 is formed to produce ice from water, which is supplied to the household refrigeration apparatus 1 via an external water supply line. In this context, ice form elements such as ice cubes or crushed ice can be produced.

[0057] Further, the ice maker 11 is a constituent of the dispenser unit 12 of the household refrigeration apparatus 1. In this advantageous implementation, the dispenser unit 12 includes an output unit 13 in addition to the ice maker 11. This output unit 13 can preferably be formed at a door 7, 8. In the shown embodiment, the output unit 13 is disposed at the door 7. This is in particular advantageous because the ice maker 11 is disposed in the left upper corner area of the total volume of the receiving space 6 with front-side view of the household refrigeration apparatus 1. For outputting produced ice form elements, short paths are achieved by this local positioning. The output unit 13 is fixedly installed at the door 7. Moreover, the output unit 13 is separated from the ice maker 11 and also decoupled from it in this context. In the closed state of the door 7, ice form elements produced by the ice maker 11 can get into the output unit 13 and be output via a front side 14 of the door 7. Thereto, it is provided that a recess is formed on the front side 14, which faces away from the receiving space 6 in the closed state of the door 7. A vessel can be placed in this recess to be able to collect the output ice form elements.

[0058] Further, the dispenser unit 12 can also be formed for outputting liquid such as water or other drinks in addition to the output of ice form elements.

[0059] In FIG. 2, an embodiment of the interior container 4 is shown in a perspective representation. The interior container 4 is preferably integrally produced from plastic, for example by deep-drawing. Injection molding can also be provided.

[0060] The interior container 4 includes multiple walls, which bound the receiving space 6. For example, the interior container 4 is formed with a first vertical side wall, which is a first wall 15 in the example, an opposing second vertical side wall 16, a rear wall 17, which is a third wall in the example, a bottom wall 18 and a ceiling wall, which is a second wall 19 in the example.

[0061] The first vertical side wall for example represents a first wall 15 of the interior container 4. In an embodiment, the ceiling wall represents a second wall 19 of the interior container 4, which is disposed angled, in particular at an angle of 90°, to the first wall 15.

[0062] The ice maker 11 includes a housing 20 (FIG. 1). A receiving space 21 of this ice maker 11 is bounded by the housing 20. The housing 20 includes a wall area 22 (FIG. 2) of the first wall 15 as a constituent. This wall area 22 is an upper wall area in the configuration according to FIG. 1 and FIG. 2. Moreover, a further constituent of the housing 20 of the ice maker 11 is formed by a wall area 23 of the second wall 19.

[0063] Moreover, the receiving space 21 is bounded by a further wall area 24. This further wall area 24 is an integral constituent of the rear wall 17 of the interior container 4. The wall areas 22, 23 and 24 directly join to each other.

[0064] Moreover, the housing 20 includes a wall unit 25 (FIG. 1), which is a component separate from the interior container 4. This wall unit 25 is a further constituent of the housing 20 and bounds the receiving space 21 of the housing 20 in addition to the wall areas 22, 23 and 24.

[0065] In FIG. 3, a perspective representation of a partial area of the household refrigeration apparatus 1 is shown. Here, the housing 20 of the ice maker 11 is in particular shown. The wall unit 25 is shown, which is here already represented in the assembled state at the interior container 4, in particular in the receiving space 6.

[0066] In the shown embodiment, the wall unit 25 includes a wall element 26. The wall element 26 is formed with an L-shape in a vertical section (sectional plane spanned by the height direction and the width direction). Thereto, the wall element 26 includes a first wall plate 27. Here, the first wall plate 27 is oriented in horizontal direction. Moreover, the wall element 26 includes a vertical wall plate. This vertical wall plate is a second wall plate 28 of the wall element 26. The wall plates 27 and 28 are in particular oriented at an angle of 90° to each other. They extend in depth direction of the household refrigeration apparatus 1 in their plate shape or in their area shape.

[0067] The wall element 26 is formed as a thermal insulating body. This means that the wall element is formed of an outer wall element 29 (FIG. 6) and an inner wall element 30 (FIG. 6). A thermally insulating material 31 (FIG. 6) is formed in a clearance between the outer wall element 29 and the inner wall element 30.

[0068] Moreover, the wall unit 25 includes a positioning bracket 32 (FIG. 3). The positioning bracket 32 is in particular integrally formed, for example of plastic. Preferably, the positioning bracket 32 is non-rectilinearly formed. The positioning bracket 32 is preferably formed as an angular part, in particular with an L-shape.

[0069] In the embodiment in FIG. 3, it is provided that the positioning bracket 32 is a component separate from the wall element 26, but is connected to the wall element 26. Here a non-destructively detachable connection is in particular provided. By such a configuration, simpler production of the individual components of the wall unit 25 is allowed on the one hand. Thereby, the disassembly is reversibly allowed on the other hand and the individual parts can for example be individually better cleaned.

[0070] As is apparent in FIG. 3, the positioning bracket 32 is disposed on a front area 33 viewed in depth direction of the housing 20, which is also the depth direction of the household refrigeration apparatus 1. In particular, the positioning bracket 32 is disposed at the front end of the housing 20. The positioning bracket 32 includes a first bracket leg 34, which is here a vertical bracket leg. Moreover, the positioning bracket 32 includes a horizontal bracket leg 35, which is here a second bracket leg. As is apparent in FIG. 3, the first bracket leg 34 joins to the wall element 26 with its free end, in particular to the first wall plate 27. There, it is non-destructively detachably fixed.

[0071] The second bracket leg 35 joins to the second wall plate 28 with its free end and is there in particular non-destructively detachably fixed.

[0072] In this context, the positioning bracket 32 includes a first end 36, which is non-destructively detachably connected to the first wall plate 27. The positioning bracket 32 includes a second end 37, which is non-destructively detachably connected to the second wall plate 28.

[0073] Moreover, the wall element 26 includes a front edge 38. This front edge 38 can be formed by a front flange. In this context, the front flange represents a front-side end part. The front edge 38 can be formed integrally with the interior part 30.

[0074] A circumferentially closed frame is formed by the front edge 38 and the positioning bracket 32. Thereby, a front-side opening of the housing 20 is also bounded.

[0075] Further, the positioning bracket 32 includes at least one stiffening rib 39. This first stiffening rib 39 is formed on an inner side of the positioning bracket 32. Preferably, it is formed angled, in particular L-shaped.

[0076] A stiffening of the wall element 27 in particular in the front area 33 is also allowed by the positioning bracket 32. In particular, an additional separate assembly part is also provided by the positioning bracket 32, by which the wall unit 25 can be disposed at the interior container 4 in improved manner.

[0077] In FIG. 4, an embodiment of the wall unit 25 is shown in a perspective representation.

[0078] In this example, the positioning bracket 32 includes a plate area 40 at the second bracket leg 34. The plate area 40 extends across the length of the second bracket leg 35 in certain areas, wherein this is viewed in width direction of the household refrigeration apparatus 1. The plate area 40 is bounded by a bounding wall 41 such that a trough area arises here. Here, the bounding wall 41 is in particular also formed for reinforcement or stiffening. The bounding wall 41 is formed uninterrupted continuously up to the end 36 of the first bracket leg 34.

[0079] Moreover, it is also provided in FIG. 4 that a further stiffening rib 42 is formed at the front-side edge of the positioning bracket 32. This stiffening rib 42 too, which extends outwards from an outer side 43 of the positioning bracket 32 in raised manner, is formed uninterrupted. This further stiffening rib 42 extends from the second end 37 of the positioning bracket 32 up to the first end 36. The stiffening rib 42 is extending in the direction of a longitudinal axis oriented along the angled shape of the positioning bracket 32.

[0080] Moreover, the positioning bracket 32 includes a further stiffening rib 44. This stiffening rib 44 is formed offset rearward to the stiffening rib 42 viewed in depth direction and in particular oriented parallel to it. It is also formed uninterrupted. A receiving groove 45 is formed between these two stiffening ribs 42 and 44, which is formed for receiving a seal.

[0081] As is moreover apparent in FIG. 4, the first bracket leg 34 includes a hole or an aperture 46. An engagement area 47 of a coupling flap 48 (FIG. 5) engages with this aperture 46. The coupling flap 48 is formed integrally with the first wall plate 27. In particular, this coupling flap 48 is formed integrally with the interior cladding or the integrally formed inner wall element 30 of the wall element 26. By this configuration, locking between the positioning bracket 32 and the wall element 26 is also formed. Thus, a locking device between the wall element 26 and the positioning bracket 32 is formed at this first end 36 of the positioning bracket 32. In particular, the coupling flap 48 is formed elastically resilient such that the coupling flap 48 is slightly deformed upon attaching the positioning bracket 32 and then the engagement area 47 snaps or locks in the aperture 46.

[0082] As is moreover apparent in FIG. 4, the wall plate 27 includes a web 49 at the end facing away from the second wall plate 28. This web 49 advantageously extends uninterrupted across the entire length of the first wall plate 27, wherein this is viewed in depth direction.

[0083] As is apparent in FIG. 4, in which the positioning bracket 32 is shown in its assembled final state with the wall element 26, the first end 36 of the positioning bracket 32 rests on this web 49 from above.

[0084] As is moreover apparent in FIG. 4, it is provided in an advantageous implementation that the wall unit 25 includes at least one positioning element. In particular, this positioning element is formed integrally with the wall unit 25. In particular, this positioning element is formed as a plug pin 50. This plug pin 50 laterally protrudes away from the web 49 in width direction. This plug pin 50 is formed to be plugged into a receptacle 51 (FIG. 2), which is formed on the inner side of the first wall 15 of the interior container 4. A pre-assembly position of the wall unit 25 at the interior container 4 is then advantageously allowed by this positioning element.

[0085] Additionally or instead, it can be provided that the positioning bracket 32 also includes a positioning element. In particular, this positioning element is formed as a plug pin 52 (FIG. 4) here too. In the shown embodiment, it is preferably formed in the horizontal second bracket leg 35. In particular, this positioning element is formed in the form of the exemplary plug pin 52 in the plate area 40 and extends upwards from a top side of the plate area 40 in height direction.

[0086] The positioning element formed as the plug pin 52 is also formed integrally with the positioning bracket 32.

[0087] Further, it is provided that the second bracket leg 35 includes a hole 53. It is formed for passing a separate fixing element, for example a screw.

[0088] In addition to the pre-assembly position for the wall unit 25 at the interior container 4 achievable by the positioning elements, in particular the plug pins 50 and/or 52, it is allowed by this hole 53 that the wall unit 25 can be correspondingly screwed to the interior container 4 for final assembly.

[0089] In this context, it is in particular additionally or instead possible that the engagement area 47 includes a hole 54, through which a fixing element separate therefrom such as in particular a screw can also be passed. Thereby, the wall unit 25 can additionally be screwed to the first wall 15. The wall unit 25 can be screwed to the second wall 19 via the hole 53.

[0090] In FIG. 4, seals 55 and 56 are moreover exemplarily shown, which then abut on the wall areas 22 and 23 in the assembled state of the wall unit 25 to allow a sealing housing 20.

[0091] Further, it is also allowed by the plug pins 50 and/or 52 that in addition to the simple adjustment of a pre-assembly position of the wall unit 25, centering of this wall unit 25 relative to the interior container 4 is also allowed. Non-destructively detachable positioning of the wall unit 25 at the interior container 4 is allowed by the plug pins 50 and 52. The pre-assembly position of the wall unit 25 at the interior container 4 is self-adherent. This means that an assembler does no longer retain himself the wall unit 25 when he produces the screw connections to produce the assembled final position of the wall unit 25.

[0092] In FIG. 5, a partial area of the wall unit 25 according to the representation in FIG. 4 is shown, wherein a perspective different from FIG. 4 is here presented. Here, the coupling flap 48 is apparent. In particular, the engagement area 47 is also shown, which is locked in the aperture 46.

[0093] In FIG. 6, the representation according to FIG. 5 is shown, wherein a horizontal sectional representation of the positioning bracket 32 in the second bracket leg 35 is illustrated here. As is apparent in this context, the positioning bracket 32 includes an integrated, blind hole-like screw boss 57 in particular in the plate area 40. Thereby, the positioning bracket 32 can also be screwed to the wall plate 28.

[0094] In FIG. 7, the positioning bracket 32 is shown in a perspective representation.

[0095] In FIG. 8, the positioning bracket 32 is illustrated in a perspective different from FIG. 7. As is apparent here, the first bracket leg 34 includes retaining elements 58 and 59 protruding downwards at its end 36. These retaining elements 58 and 59 can be plug flaps or locking elements. Thereby, the positioning bracket 32 can additionally be non-destructively detachably attached to the wall element 26 in improved manner.

[0096] In advantageous implementation, it is provided that the positioning bracket 32 includes at least one plug element 60, here preferably two separate and spaced plug elements 60 and 61, at the second end 37. These plug elements 60, 61 are formed integrally with the positioning bracket 32. Upon assembly of the positioning bracket 32 to the wall element 26, these plug elements 60 and 61 are plugged into corresponding receptacles, one receptacle 62 of which is apparent in FIG. 6. This configuration too represents a fixing device, which is non-destructively detachable.

[0097] In FIG. 9, a partial area of the wall unit 25 is shown in a vertical sectional representation. Here, the sectional line is drawn through the plug pin 52.

[0098] As is apparent, the plate area 40 includes a depression 63. The hole 53 is formed in this depression 63. The hole 53 is in particular formed as an elongated hole. Preferably, the hole 54 is also formed as an elongated hole.

[0099] As is apparent in FIG. 9, a washer 64 is introduced into this depression 63, through which a screw 65 is passed. By the configuration of the hole 53 as an elongated hole, a certain backlash and thus a tolerance for positional adjustment is here allowed since the washer 64 is disposed in the hole 53 with backlash.

[0100] In FIG. 9, a further washer 66 and a screw 67 are moreover shown.

[0101] The washer 66 is in particular formed corresponding to the washer 64 and correspondingly plunges into the hole 54. Her too, a certain positioning with backlash is thus allowed such that a tolerance compensation is allowed. The wall unit 25 can be screwed to a screw boss 71, which is integrally formed in the wall area 22, by the screw 67 such that a screw connection is formed at this place.

[0102] In FIG. 10, the partial section in FIG. 9 is shown in an enlarged representation, in which the screw 65 is illustrated. This backlash and thus this tolerance compensation are symbolized by the arrows in FIG. 10.

[0103] In FIG. 11, the assembled state of the wall unit 25 to the interior container 4 in this area of the positioning bracket 32 according to FIG. 10 is shown in a perspective sectional representation. Here, it is apparent that the positioning element or the plug pin 52 plunges into a receptacle 68, which is formed integrally with the second wall 19, to allow the pre-assembly position and in particular also centering of the wall unit 25 around the interior container 4. The receptacle 68 is in particular formed as a blind hole. Moreover, a seal 69 is also shown in FIG. 11, which is disposed in the receiving groove 45.

[0104] In FIG. 12, it is shown in a perspective horizontal sectional representation, how the wall unit 25 is fixed to the first wall 15 in the area of the first end 36 of the positioning bracket 32.

[0105] In FIG. 13, a further embodiment for a wall unit 25 is shown in a perspective representation. In contrast to the representation according to FIG. 4, it is here provided that a locking element 70 is formed integrated and thus integrally on the wall plate 27 instead of the plug pin 50. In particular, the locking element 70 is disposed at the web 49. In particular, the locking element 70 is integrated in the inner wall element 30.

[0106] This locking element 70 can lock in a corresponding receptacle formed in the wall area 22. Moreover, in contrast to FIG. 4, the configuration of the positioning bracket 32, in particular of the second bracket leg 35, is slightly different from the configuration in FIG. 4. However, the basic and essential functions and elements are provided here too. In particular, this relates to the positioning element in the form of the plug pin 52 as well as the plug elements 60, 61, the hole 53 and preferably also the screw boss 57.

[0107] In FIG. 14, the household refrigeration apparatus 1 is shown in the area of the ice maker 11 with the finally assembled housing 20 in an enlarged representation. The wall unit 25 is represented in its end position at the interior container 4 in this context.

[0108] As is also apparent in FIG. 14, the front edge 38 is non-destructively detachably connected, in particular locked, to the outer wall element 29. Thereto, two locking elements 72 and 73 are exemplarily apparent.

[0109] Further, it is provided that in an embodiment, which can be provided independently of the previous explanations with regard to the configuration of the wall unit 25, a wall step 74 is formed at the first wall 15 and there in the wall area 22, which bounds the receiving space 21 of the ice maker 11 and is associated with the housing 20.

[0110] In FIG. 15, the housing 20 is shown in a vertical sectional representation, wherein the wall step 74 is here also apparent.

[0111] The wall step 74 includes a protrusion 75. The protrusion 75 protrudes into the receiving space 21 of the ice maker 11 viewed in width direction of the household refrigeration apparatus 1. This protrusion 75 is formed as a condensation water drip bar 76.

[0112] A recess 77 is formed below the protrusion 75 in height direction. The wall element 26 plunges into this recess 77 viewed in width direction. In particular, this plunging is such that the web 49 is completely disposed in this recess 77. In particular, the protrusion 75 further protrudes into the receiving space 21 than the groove 49 is wide in this width direction. Thereby, the dripping of condensation water from the condensation water drip bar 76 is allowed such that water cannot get laterally past the groove 49 and thus into the recess 77. The condensation water drips from the condensation water drip bar 76 directly onto that area of the inner wall element 30, which inwardly adjoins to the web 49.

[0113] In FIG. 16, an enlarged representation of the view in FIG. 15 is shown, wherein that section in the area of the protrusion 75 and the recess 77 is shown here. Preferably, it is provided that an angle α, which is measured between a protrusion wall 79 of the protrusion 75 and the downward adjoining wall section 78 of the first wall 15 or the wall area 22, is less than or equal to 110°, in particular less than or equal to 90°.

[0114] In FIG. 17, a partial section of the interior container 4 with view to the rear wall 17 is shown. Here, a viewing direction into the receiving space 6 is illustrated. In the wall area 24 of the rear wall 17, a drain gutter 80 is shown formed integrally therewith. Condensation water, which occurs in the ice maker 11, can in particular be conducted to this drain gutter 80 via the first wall plate 27. Thereto, the inner wall element 30 of the wall element 26 is preferably obliquely rearward inclined in particular in the area of the first wall plate 27. In this context, condensation water, which drips to the top side of the inner wall element 30 via the condensation water drip bar 76, can in particular be conducted to the rear in defined and targeted manner and thus then gets into the drain gutter 80.

[0115] The drain gutter 80 includes a drain stub 81. A drain line 90, as it is shown in FIGS. 21 and 22, can be connected to the drain stub 81.

[0116] The drain gutter 80 includes a front gutter edge 82 viewed in depth direction. This front gutter edge 82 can also serve as a rest for a web of the first wall plate 27.

[0117] In addition or instead, it can be provided that a pedestal base 83 formed spaced from and independently of the front gutter edge 82 is integrally formed in the interior container 4. This pedestal base 83 can serve as a rest for the first horizontal wall plate 27. As it is moreover apparent in FIG. 17, the rear wall 17 includes two screw domes 84 and 85 in the embodiment. The screw domes 84 and 85 are formed integrally with the rear wall 17. They are preferably formed in the area of the pedestal base 83. The wall element 26 can be screwed to the rear wall 19 by these screw domes 84 and 85.

[0118] In FIG. 18, the interior container 4 is shown in its upper area, wherein a view to the rear wall 17 from behind is provided here. Thus, a view is directed from the foam side to the rear wall 17, which means that it is looked from the clearance 5 towards the rear wall 17.

[0119] Here, it is apparent that a pedestal 86 is integrally formed at the rear wall 17 in an advantageous implementation. This pedestal 86 is formed offset rearward with respect to a base plate 87 of the rear wall 17 viewed in depth direction. Thus, the pedestal 86 is formed backpack-like at the base plate 87. As is apparent in FIG. 18, the drain gutter 80 is formed at the lower end of the pedestal 86, in particular formed completely within the pedestal 86. The drain gutter 80 is therefore disposed offset rearward with respect to the base plate 87 viewed in depth direction. In particular, the drain gutter 80 is thus virtually rearward offset from the volume, which is bounded by the base plate 87, and thus rearward offset towards the clearance 5. Thus, the drain gutter 80 is displaced into the area, in which the insulating foam is disposed.

[0120] Moreover, it is also apparent in FIG. 18 that the drain gutter 80 bulges out rearward with respect to the pedestal 86, which is trough-like formed, and thus forms a bead-like protrusion towards the bottom and the rear. Preferably, the drain gutter 80 extends across the entire width of the pedestal 86.

[0121] In FIG. 19, the interior container 4 is shown in a transparent side view in an implementation. The above mentioned positional configurations of the drain gutter 80 to the base plate 87 are apparent. Moreover, it is also apparent that the protrusion 75 extends uninterrupted from the front end of the housing 20 up to the drain gutter 80.

[0122] In FIG. 20, a partial area of the interior container 4 is shown in an enlarged representation, as it is illustrated in FIG. 19. Here, that partial area with the pedestal 86 and the drain gutter 80 is in particular again clarified.

[0123] In FIG. 21, the interior container 4 is shown in the upper area in a sectional representation, wherein the wall unit 25 is here also shown in the assembled final state and is apparent in a vertical sectional representation.

[0124] In FIG. 22, the rear area with the drain gutter 80 is shown in an enlarged representation. As is apparent, the first wall plate 27 includes a web 88 protruding rearward viewed in depth direction. This rearward protruding protrusion in the form of the web 88 extends up into the drain gutter 80. In particular, this web 88 is disposed upward offset and contactless to the front gutter edge 82, as it is shown in FIG. 22. The web 88 extends in depth direction for example as far as it completely covers the front gutter edge 82.

[0125] Thereby, it is also allowed that the drain of the condensation water from the first wall plate 27 is securely effected into the drain gutter 80 on the one hand. On the other hand and independently thereof, it is thereby then also allowed that the first wall plate 27 is positionally securely and mechanically stably retained and virtually rests on this front gutter edge 82. Thereby, it is in particular also allowed that a pre-assembly position of the wall unit 25 is now also securely achieved at this location in addition to the previously mentioned examples with the positioning elements or instead thereof.

[0126] In addition or instead, it can be provided that the first wall plate 27 rests on the pedestal base 83, as it is shown in FIG. 22. The screw joint or a screw connection, in particular of the first wall plate 27 to the screw boss 84, is also shown, wherein a screw 89 is illustrated here. In FIG. 22, a state is shown, in which the web 88 protrudes into the drain gutter 80 viewed in depth direction, but is disposed spaced from the front gutter edge 82 at this location.

[0127] In FIG. 23, in a perspective sectional representation, which is slightly offset to the right in width direction with respect to the representation in FIG. 22, a corresponding area is shown as it is represented in FIG. 22.

[0128] Further, in the embodiment, but which is not to be conclusively understood, four screw connections are provided, by which the wall unit 25 is fixed to the interior container 4. This relates to the screw connection with the screw 67, the screw connection with the screw 65 and the screw connections with screws 89 at the screw domes 84 and 85. More or less screw connections can also be provided.

[0129] In a method for assembling the housing 20 of the ice maker 11, the interior container 4 is produced and provided integrally with the first wall 15 and with the second wall 19 disposed angled thereto. Furthermore, a wall unit 25 separate from the interior container 4 is provided, wherein the wall unit 25 includes at least one positioning element, which is formed integrally with the wall unit 25. The positioning elements are produced as plug pins 50 and/or 52 and/or as a locking element 70. This wall unit 25 is introduced into the receiving space 6 of the interior container 4. In particular, the web 88 is first placed on the pedestal base 83. At the same time or subsequently, the plug pin 50 is introduced into the receptacle 51 and/or the plug pin 52 is introduced into the receptacle 68 in the embodiment. Since the plug pins 50 and 52 are oriented in different spatial directions, namely in width direction and in height direction, a pre-assembly position in height direction and in width direction, in particular in the front area 33, can be autonomously retained by this implementation. The same is achieved with the locking element 70 if it is formed instead of the plug pin 50. The plug pin 52 can for example also be replaced with a locking element. By the rest of the web 88 on the pedestal base 83 in the rear area of the housing 20, the pre-assembly position is securely and autonomously retained there too.

[0130] In this pre-assembly position, the subsequent screwing of the screws, which are provided for producing the screw connections, and by which the final position of the wall unit 25 at the interior container 4 is produced, can be effected without retaining the wall unit 25 by an assembler. The assembler then has both hands free to produce the screw connections.

[0131] Generally and independently of the explained embodiments, individual advantageous developments of an ice maker, in particular the housing of the ice maker, of the household refrigeration apparatus can be provided.
