Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a Continuation-In-Part of U.S. patent
application Ser. No. 16/202,993, filed Nov. 28, 2018; the prior
application is herewith incorporated by reference in their
entirety.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] An aspect of the invention relates to a household
refrigeration apparatus including an ice maker including a
specifically constructed housing.
[0003] Household refrigeration apparatuses are known in diverse
configurations. In this context, it is also known that an interior
container bounds a receiving space for a household refrigeration
apparatus. This receiving space is usually a refrigerating
compartment. A partial area is occupied by an ice maker in this
receiving space. Thereto, it is known that the ice maker is
separated from the remaining volume of the refrigerating
compartment. In this context, it is provided that a housing area of
the housing of the ice maker is formed by a separate wall element,
which is attached to inner sides of walls of the interior container
in the interior of the receiving space of the interior
container.
[0004] Thus, it is for example known from U.S. Patent Application
Publication No. 2013/0263620 A1 to form such an ice maker in the
left upper corner area in the refrigerating compartment with
front-side view of the household refrigeration apparatus. With the
ice maker, ice form elements, for example ice cubes or crushed ice,
can be produced from supplied water. These ice form elements can be
output via an output unit formed at a door of the household
refrigeration apparatus.
[0005] In the known design of the household refrigeration
apparatus, the separate wall element, which is a constituent of the
housing of the ice maker, is attached to walls of the interior
container by multiple screw connections. Therein, it is required
that this wall element is additionally retained by an assembler
himself upon assembly in order to be able to generate the screw
connections. This is expensive and can also result in incorrect
positions of the wall element. Thereby, the accurate position of
the wall element at the interior container cannot be satisfied,
whereby impairments in the thermal insulation at the interfaces
between the wall elements and the inner side of the walls of the
interior container optionally also arise.
[0006] A further disadvantage of the known design is to be regarded
in that the wall element is formed with a circumferential frame in
the front-side area, which is integrally configured. A bracket,
which joins to plate elements of the wall element, is formed
integrally with these plate elements. Thereby, this integral wall
element is very complexly configured in its shape. Therefore, it is
also difficult to clean, which optionally results in hygienic
impairments of the ice maker.
[0007] A further disadvantage of the known household refrigeration
apparatus is to be regarded in that condensation water optionally
occurring in the housing cannot be transported away. Thereby too,
hygienic impairments can occur.
SUMMARY OF THE INVENTION

as a condensation water drip bar.
[0016] According to another aspect, the protrusion includes a
protrusion wall wherein an angle between the protrusion wall and a
further wall section of the first wall downwardly adjoining to the
protrusion is less than 90.degree..
[0017] According to another aspect, the household refrigeration
apparatus has a depth direction wherein the protrusion extends
across the entire length of the housing of the ice maker in this
depth direction.

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.degree., 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.degree. 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 .alpha., 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.degree., in particular less than or equal to 90.degree..
[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.
