Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit, under 35 U.S.C. .sctn.
119, of German patent application DE 10 2017 205 089.6, filed Mar.
27, 2017; the prior application is herewith incorporated by
reference in its entirety.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The invention relates to a domestic refrigeration appliance
with a chamber for holding food, which is delimited by walls of an
inner container of the domestic refrigeration appliance. The
domestic refrigeration appliance also has an inner lining, which
comprises an air duct unit of the domestic refrigeration
appliance.
[0003] Such a domestic refrigeration appliance is known from
published, non-prosecuted German patent application DE 10 2014 224
648 A1.
[0004] Production tolerances can result when producing the inner
container, which is generally produced as a single-piece plastic
container, for example by deep-drawing. When the inner lining is
subsequently incorporated in this chamber, which is delimited by
the walls of the inner container, tolerances can therefore result.
With conventional configurations compensation for such tolerances
is associated with relatively large gap dimensions at the left-hand
and right-hand edges when viewed from the front. Such
configurations can also cause the inner lining to be positioned in
an undesirable manner and mechanically stable fastening of the
inner lining to be impaired.
SUMMARY OF THE INVENTION
[0005] It is the object of the present invention to create a
domestic refrigeration appliance with an improved inner lining, the
assembly of which can be achieved with better tolerance
compensation.
[0006] This object is achieved by a domestic refrigeration
appliance and a method as set out in the independent claims.
[0007] One aspect of the invention relates to a domestic
refrigeration appliance with at least one chamber for holding food.
The domestic refrigeration appliance has an inner container, the
walls of which delimit the chamber. The domestic refrigeration
appliance also has an inner lining, which is a separate unit from
the inner container. The inner lining contains an air duct unit.
This air duct unit allows air to be conducted in a defined manner
in the domestic refrigeration appliance and thus also to be
supplied to a specific chamber, so that this chamber can be fed
specifically cooled air by this air duct unit. The air duct unit
can thus be part of a cooling system of the domestic refrigeration
appliance. The inner lining has a first lining wall and second
lining wall separate therefrom. The inner lining is thus configured
with multiple parts. These at least two separate lining walls are
arranged adjacent to one another in the widthwise direction of the
domestic refrigeration appliance, being positioned with an overlap
with one another in this widthwise direction. Such a configuration
means that the two lining walls form a continuous, unbroken wall
but it is still possible to vary the width of the inner lining due
to the separation of these two walls in the widthwise direction.
This configuration therefore allows the inner lining to be adjusted
for tolerances resulting in particular due to the inner container.
This makes incorporation easier and undesirable gap dimensions can
be avoided or adjustment for corresponding gap dimensions is
improved due to the possibility of varying the width of the inner
lining. This also allows more stable incorporation of the inner
lining.
[0008] Provision can be made for the overlap between the two lining
walls to be configured with play. This means in particular that the
two lining walls can be arranged relative to one another in the
widthwise direction in such a manner that the overlap is present
between the lining walls but the lining walls are not brought
together to the maximum. This specifically allows adjustment for
different incorporation situations with the different tolerances
that may be present and have to be compensated for. This
configuration with an overlap with play specifically allows such a
variation of width in a very advantageous manner.
[0009] It is then possible in particular for an assembly position
reached between the two lining walls and also the overlap between
these lining walls, which may also have some play, to be fixed. To
this end a fixing unit can be provided, which is configured as a
mechanical component, for example with brackets or latching
elements. Fixing can also be achieved by introducing a thermally
insulating material, in particular an insulation space, into a
space between the inner container and an outer housing of the
housing of the domestic refrigeration appliance. This causes the
walls of the inner container to be pushed or deformed slightly in
some instances in the direction of the chamber, so that the inner
lining, which extends in the widthwise direction of the domestic
refrigeration appliance, is then also fixed or clamped between the
opposing vertical side walls of the inner container.
[0010] This is also very advantageous if the overlap is configured
with play, as this allows a certain bringing together of the lining
walls in the widthwise direction, without the inner lining arching
or bulging to the rear or front.
[0011] Provision is preferably made for the overlap on the side
facing the chamber to be covered by a cover that is separate from
the lining walls. This conceals the overlap in the direction of the
door and thus from a user's view. On the one hand this results in a
less busy visual appearance. Significantly however it means that
the overlap cannot be damaged and other objects cannot strike it
directly. The mechanical coupling between the lining walls at this
overlap is also protected as a result and damage or penetration by
other foreign bodies can advantageously be prevented.
[0012] Provision is preferably made for the cover to be a cover
plate. This gives rise to a very large, in particular single-piece
part, which covers the entire configuration of the overlap at the
front. Such a configuration also results in an intrinsically rigid
and yet still flat part.
[0013] Provision is preferably made for the cover to have a front
wall, which is part of the air duct unit and delimits an air duct
volume of this air duct. This makes the cover multifunctional and
even though the inner lining is intentionally to be made up of
multiple parts, the number of components is minimized within these
multiple parts.
[0014] Provision is preferably made for the cover to be arranged on
at least one lining wall in such a manner that it can be removed
non-destructively. This allows it to be removed and replaced in a
reversible manner allowing access to parts of the inner lining
behind this cover for maintenance work or assembly purposes. It
also allows it to be cleaned and any parts that might collect in
the air duct volume can also be easily removed.
[0015] Provision can be made for the cover to be attached or
latched to at least one lining wall. This is a simple and yet
highly functional mechanical connection, which can also be undone
or restored easily by a fitter or user. This always ensures a safe
assembly and disassembly scenario.
[0016] Provision is preferably made for one of the two lining walls
to have a hollow holder, which is entered by an insertion element
configured on the other lining wall to form an overlap. This
configuration allows the lining walls to be coupled mechanically in
a simple manner in this widthwise direction. Such a configuration
also means that the complexity of the shape of the lining walls can
be kept relatively simple, so that such geometries can be
reproduced easily and accurately when producing a single piece,
thereby preventing undesirable clamping or spreading when
assembling these two lining walls with one another.
[0017] Provision can be made for the hollow holder to be configured
as a slot. In this context it is as it were a groove, into which
the insertion element, which is then preferably a web or band or
lug, can be inserted. This advantageously specifically allows the
overlap in the widthwise direction over the entire height of the
two lining walls in the heightwise direction, preventing
undesirable holes or leakage at this overlap interface. This
ensures the lining walls overlap in the widthwise direction over
the entire height.
[0018] This configuration also ensures a certain relative
positioning of the lining walls in a further spatial direction,
specifically the depthwise direction, so that these lining walls do
not slide apart in an undesirable manner.
[0019] In a further embodiment provision can be made for the hollow
holder to have a holder volume, which is delimited by at least one
holder wall that can be deformed elastically in a defined manner.
When the lining walls are in the assembled state relative to one
another or with one another, the deformable holder wall rests in a
pretensioned manner against a stop, which is configured on the
other lining wall. This configuration not only brings about simple
insertion, it also establishes an additional active mechanical
connection, specifically generating a defined pretensioning force,
which on the one hand favors the mechanical connection at the
overlap and on the other hand stabilizes the relative position of
the lining walls more effectively.
[0020] In a further embodiment provision can be made for the hollow
holder to have a holder volume, which is delimited by at least one
holder wall that can be deformed elastically in a defined manner.
When the lining walls are in the assembled state relative to one
another, the deformable holder wall is latched with a latching head
in a latching holder, which is configured on the other lining wall.
This is also an advantageous alternative embodiment, which allows
secure positioning of the lining walls relative to one another and
secure retention at the connection interface of the lining
walls.
[0021] In a further alternative embodiment provision can be made
for the hollow holder to have a holder volume, which is delimited
by at least one holder wall. When the lining walls are in the
assembled state, the holder wall rests against an elastically
deformable stop, which is configured on the other lining wall and
is pretensioned in the assembled state. This also has the
advantages cited for the alternative embodiments mentioned above.
In one advantageous embodiment provision is made for at least one
lining wall to rest against a rod-type profile of the domestic
refrigeration appliance, which is separate from the lining wall, at
an edge facing away from the second lining wall. Such a
configuration allows even greater assembly stability with the inner
lining. In particular this profile part then rests against a wall,
in particular a vertical side wall, of the inner container. This
additional profile part further stabilizes the connection with a
lining wall and more effective coupling to a wall of the inner
container is achieved by way of this profile part.
[0022] This profile part is preferably configured as a hollow metal
profile. In a sectional view perpendicular to a longitudinal axis
of the profile part the profile part is configured as angular, in
particular square, in its hollow body region. A lug can also be
configured to project from this hollow body region, being able to
serve to connect to other components.
[0023] Provision is advantageously made for this profile part to be
a multifunctional part. In addition to the connection functionality
for a lining wall it can also be used as a support part for a shelf
which can be introduced into the chamber and divides the volume of
the chamber into sub-volumes. As such a profile part is also very
stable mechanically in respect of its configuration it can easily
assume the support functionality not only for the at least one
shelf but also for the stored goods positioned thereon.
[0024] A shelf in this context can also be configured at least
partially of real glass for example.
[0025] The profile part is in particular configured as a single
piece.
[0026] In one advantageous embodiment the inner lining has a third
lining wall which is separate from the first lining wall and the
second lining wall. The third lining wall is arranged with a
further overlap with the second lining wall when viewed in the
widthwise direction of the domestic refrigeration appliance. Such
an embodiment allows the advantages cited above to be achieved even
more effectively and tolerances can be compensated for particularly
advantageously.
[0027] When viewed in the widthwise direction the second lining
wall is advantageously arranged between the first and third lining
walls and only the second lining wall is additionally also part or
a boundary wall of an air duct volume of the air duct unit. With
such a configuration the air duct unit is thus configured in the
center of the inner lining when viewed in the widthwise
direction.
[0028] Provision can be made for the second lining wall not to be
configured as even but to be shaped as specifically uneven. It is
therefore possible to create a corner-free contour with this uneven
shape, as is the case for example with a channel. A specific
angular shape can also be configured, for example a trapezoidal
shape
[0029] Provision is preferably made for the second lining wall to
be a rear wall of the air duct unit when viewed in the depthwise
direction, being advantageously covered at the front by the
separate cover already mentioned above. With such a configuration
therefore the front of the air duct volume is delimited by a
boundary wall in the form of the cover and the rear is delimited by
a boundary wall in the form of the second lining wall.
[0030] In one advantageous embodiment provision can be made for the
domestic refrigeration appliance to have a further separate rail or
strip, which is arranged on the outside of the abovementioned
profile part and is thus arranged at a distance in the widthwise
direction from the lining wall which opens out at the profile part.
Thus with such a configuration a gap is formed on a front wall of
the profile part between this lining wall opening out thereon and
the additional strip at a distance therefrom in the widthwise
direction. This gap therefore allows access to the profile part at
the front and makes it possible to suspend or otherwise arrange an
abovementioned shelf from or on the profile part. This further
strip is preferably configured as a single piece and extends over
the entire height of the lining wall. In particular this strip can
be configured as L-shaped in cross section.
[0031] Provision can be made for the mechanical connection of a
lining wall to a profile part to be implemented by a plug-type
connection or a latching connection.
[0032] The air duct unit is preferably what is known as a
multi-airflow system. Such a configuration allows a very regular
air distribution in the chamber.
[0033] The domestic refrigeration appliance preferably has a second
chamber for holding food, this being separated from the first
chamber. Provision is made in particular for the two chambers to be
configured one above the other when viewed in the heightwise
direction of the domestic refrigeration appliance. Provision can be
made in particular for the upper chamber to be a chiller
compartment. This can be closed in particular by two separate
doors, which are each arranged pivotably on the housing. The two
doors are arranged at the same height in the heightwise direction
and adjacent to one another in the widthwise direction and can be
actuated independently of one another. They can each be pivoted by
way of their own vertical rotation axis. The further, in particular
lower, chamber is preferably a freezer compartment. It can
preferably be closed by a further front door. Provision can
preferably be made here for this further door to be a front wall of
a drawer, which can be pushed into and pulled out of this second
chamber in the depthwise direction.
[0034] Provision can also be made for the domestic refrigeration
appliance to have at least one third chamber, which can also be
closed by an again separate door, which can be actuated
independently of the abovementioned other doors, thereby allowing
individual access to this third chamber. Provision can also be made
in particular here for this further door to be a front wall of a
drawer preferably provided here too.
[0035] A further aspect of the invention relates to a method for
producing a domestic refrigeration appliance, wherein an inner
container is provided, which delimits a chamber for holding food by
means of walls. The domestic refrigeration appliance is configured
with an inner lining, which contains an air duct unit. The inner
lining is incorporated in the chamber. The inner lining is provided
with a first lining wall and second lining wall that is separate
therefrom. The two lining walls are arranged adjacent to one
another in the widthwise direction of the domestic refrigeration
appliance and are positioned with an overlap with play with one
another in this widthwise direction. This play orients these lining
walls in an assembly position relative to one another in the
overlapping state and this assembly position is subsequently fixed.
Such a procedure allows more effective compensation for production
tolerances of individual components of the domestic refrigeration
appliance, in particular of the inner container, and the inner
lining can be incorporated very accurately and without undesirable
position tolerances.
[0036] The terms "top", "bottom", "front", "rear", "horizontal",
"vertical", "depthwise direction", "widthwise direction",
"heightwise direction", etc. specify the positions and orientations
present when the apparatus or appliance is used and arranged in the
correct manner and for an observer standing in front of the
appliance and looking in the direction of the appliance.
[0037] Further features of the invention will emerge from the
claims, the figures and the description of the figures. The
features and feature combinations cited above in the description
and the features and feature combinations cited in the following in
the description of the figures and/or simply shown in the figures
can be used not only in the combination specified in each instance
but also in other combinations without departing from the scope of
the invention. Thus embodiments which are not shown specifically in
the figures and described but emerge and can be generated from the
embodiments described by way of separate feature combinations
should also be considered to be included in and disclosed by the
invention. Embodiments and features which therefore do not have all
the features of an originally formulated independent claim should
therefore also be considered to be disclosed. Embodiments and
feature combinations, in particular those resulting from the
embodiments set out above, which go beyond or deviate from the
feature combinations set out in the claim references should also be
considered to be disclosed.
[0038] Other features which are considered as characteristic for
the invention are set forth in the appended claims.
[0039] Although the invention is illustrated and described herein
as embodied in a domestic refrigeration appliance with an inner
lining with multiple separate lining walls as well as a method for
producing a domestic refrigeration appliance, it is nevertheless
not intended to be limited to the details shown, since various
modifications and structural changes may be made therein without
departing from the spirit of the invention and within the scope and
range of equivalents of the claims.
[0040] The construction and method of operation of the invention,
however, together with additional objects and advantages thereof
will be best understood from the following description of specific

DETAILED DESCRIPTION OF THE INVENTION
[0049] Identical elements or those of identical function are shown
with the same reference characters in the figures.
[0050] Referring now to the figures of the drawings in detail and
first, particularly to FIG. 1 thereof, there is shown a schematic
diagram of a domestic refrigeration appliance 1. The domestic
refrigeration appliance 1 here is configured as a combined
refrigerator/freezer. The domestic refrigeration appliance 1 has a
housing 2, which has an outer housing 3 and an inner container 4.
Configured between the outer housing 3 and the inner container 4 is
a space 5, which is at least partially filled with a thermally
insulating material, in particular insulating foam.
[0051] The inner container 4 has multiple walls, here specifically
a first vertical side wall 6, an opposing second vertical side wall
7, a rear wall 8, a bottom wall 9 and a top wall 10. The inner
container 4 is configured, preferably deep-drawn, as a single
piece, in particular made of plastic.
[0052] At the front the inner container 4 has a loading opening 11,
through which goods to be stored can be introduced into and removed
from a chamber 12 for holding food delimited by the abovementioned
walls 6 to 10. In the illustrated exemplary embodiment the chamber
12 is a first chamber, in this instance a chiller compartment for
example.
[0053] In the illustrated exemplary embodiment this first chamber
12 can be closed by a first door 13 and a second door 14 that is
separate therefrom. The two doors 13 and 14 are in particular
visible front parts, which can be actuated independently of one
another. In the present exemplary embodiment they close a single,
continuous chamber 12. The two doors 13 and 14 can each be pivoted
by way of a pivot axis oriented in the heightwise direction
(y-direction) and are thus arranged pivotably on the housing 2.
[0054] In the illustrated exemplary embodiment the domestic
refrigeration appliance 1 has a second chamber 15, in this instance
a freezer compartment. In the illustrated exemplary embodiment this
second chamber 15 is arranged below the first chamber 12 in this
abovementioned heightwise direction. The second chamber 15 is also
delimited by walls of an inner container and can be closed at the
front by a door 16. The door 16 here is in particular a front wall
of a unit configured as a drawer. This drawer can be pushed into
and pulled out of the second chamber 15 in a linear manner in the
depthwise direction (z-direction).
[0055] The domestic refrigeration appliance 1 also has an inner
lining 17, which is a separate unit from the inner container 4 and
is arranged in the inner container 4. It is thus arranged in the
first chamber 12 here.
[0056] The inner lining 17 is thus also a separate unit from the
rear wall 8.
[0057] FIG. 2 shows a perspective diagram of an exemplary
embodiment of the inner lining 17. It is configured with multiple
parts. It has a first lining wall 18. It also has a second lining
wall 19. These two lining walls 18 and 19 are arranged with an
overlap 20 with one another in the widthwise direction
(x-direction), which is also the widthwise direction of the
domestic refrigeration appliance 1.
[0058] Provision is made in the exemplary embodiment for the inner
lining 17 to have a third separate lining wall 21. It adjoins the
second lining wall 19 and is arranged with a further overlap 22
with the second lining wall 19 when viewed in the widthwise
direction.
[0059] When viewed in the widthwise direction therefore the lining
walls 18, 19 and 21 are arranged in a line with one another, but
each with an overlap at their interfaces.
[0060] The inner lining 17 also has yet another separate component
in the form of a cover 23, in this instance a cover plate. The
cover 23 is arranged at the front and conceals the overlaps 20 and
22 at the front. When incorporated therefore the first lining wall
18, the third lining wall 21 and the cover 23 form visible parts in
the chamber 12. The second lining wall 19 is covered by the cover
23 at the front.
[0061] The inner lining 17 also has an air duct unit 24, which is
what is known as a multi-airflow system. In this context the air
duct unit 24 has an air duct volume 25, which is delimited by
boundary walls. The boundary walls here are formed by the second
lining wall 19 and the cover 23.
[0062] Provision is also made in an advantageous embodiment for the
inner lining 17 to have a first profile part 26 that is separate
from the abovementioned walls and the cover 23. The first lining
wall 18 opens out at this rod-type profile part 26, which is in
particular a single-piece metal profile, being in particular
fastened thereto, preferably being fastened thereto in such a
manner that it can be removed non-destructively.
[0063] The inner lining 17 also preferably has a second profile
part 27, which is configured in the same way as the first profile
part 26. The further profile part 27 is configured in such a manner
that the third lining wall 21 opens out at it, in particular is
fastened to it in the same way as the first lining wall 18 is
fastened to the first profile part 26.
[0064] A first strip 28, which is separate from the other
components, is also provided, being arranged at a distance from the
first profile part 26 and having no contact with the first lining
wall 18. When viewed in the widthwise direction the first lining
wall 18 and this strip 28 are arranged at a distance from one
another so that a gap 29 is formed, through which a front face 30
of the first profile part 26 can be accessed at the front.
[0065] A further separate strip 31 is similarly provided, being
arranged on the second profile part 27, in particular as in the
abovementioned configuration being arranged at a distance in the
widthwise direction from the third lining wall 21. A gap 32 is
preferably formed here too, being accessible at the front and
through which a front face 33 of the second profile part 27 is
accessible.
[0066] Shelves or separating plates (not shown), which can be
introduced into the chamber 12, can be fastened to, for example
suspended from, the profile parts 26 and 27 by way of these gaps 29
and 32.
[0067] FIG. 3 shows an enlarged diagram of a partial detail III in
FIG. 2. It can be seen here that the overlap 20 is configured with
play in this widthwise direction. In the illustrated exemplary
embodiment the first lining wall 18 has a hollow holder 34,
configured here as a slot or groove, on the side or edge facing the
second lining wall 19. Configured on the side or edge of the second
lining wall 19 facing the first lining wall 18 is an insertion
element 35 provided for engagement and molded on as a single piece
in the form of a lug or web. In the coupled state with overlap in
the widthwise direction this insertion element 35 enters the hollow
holder 34.
[0068] It can also be seen that the second lining wall 19 has a web
36 that projects forward and is thus oriented in the depthwise
direction, the cover 23 being connected mechanically thereto with a
coupling web 37. Provision is thus made for the second lining wall
19 and the cover 23 to overlap in the depthwise direction
(z-direction), in order to establish a mechanical connection here
too. Provision can be made for the cover 23 to be attached or
latched to the second lining wall 19. To this end corresponding
latching elements can be molded as a single piece onto these webs
36 and 37. The configuration is also similar in the region of the
further overlap 22, for which see the description given relating to
the overlap 20 in FIG. 3.
[0069] FIG. 4 shows an enlarged diagram of the partial detail IV in
FIG. 2. As can be seen here, the first lining wall 18 has a further
web 38, which is molded on as a single piece and oriented in the
depthwise direction, on its rear face. This forms a manner of stop,
which rests against a side wall 39 of the profile part 26. The
first lining wall 18 overlaps with the first profile part 26 in the
widthwise direction, as shown in FIG. 2 and FIG. 4. The first
lining wall 18 also rests against an abovementioned front face 30
of the profile part 26 and thus conceals parts of the profile part
26 at the front. A corresponding configuration, shown in FIG. 4 for
the arrangement of the first lining wall 18 and the first profile
part 26 as well as the strip 28, can also be seen for the third
lining wall 21, the second profile part 27 and the further strip
31.
[0070] FIG. 5 shows a top view of a further exemplary embodiment of
the inner lining 17 with sub-components, in particular in the
region of the first lining wall 18, the second lining wall 19 and
the cover 23. As can be seen here, the first lining wall 18 is
inserted or latched into the first profile part 26, in particular
using a corresponding coupling means 40.
[0071] The mechanical coupling between the first lining wall 18 and
the second lining wall 19 is configured in an alternative manner
here. The hollow holder 34 here is different from the embodiment in
FIG. 2 and FIG. 3. There is no slot-type or groove-type
configuration here. Instead a holder volume 41 of this hollow
holder 34 is delimited by an elastically deformable holder wall 42.
The web 25 of the second lining wall 19 molded at the edge enters
therein. A stop 43 is also molded as a single piece on the rear of
the lining wall 19. The elastically deformable holder wall 42 rests
against this in a pretensioned manner, so that a pressing force P
acts in the direction of the arrow, as shown in FIG. 5. The
pretensioning force causes the first lining wall 18 to be pressed
onto the profile part 26.
[0072] FIG. 5 also shows the coupled state between the webs 36 and
37, being implemented in particular by a plug-type connection or a
latching connection.
[0073] FIG. 6 shows a further exemplary embodiment in a view
corresponding to the one in FIG. 5. In this embodiment the hollow
holder 34 is again not configured in the manner of a slot or groove
but is configured with a holder volume 41, as in FIG. 5. The holder
wall 42, which is also elastically deformable here, is configured
here at its front free end with a latching head 44, which latches
in a latching holder 45, which is configured as a single piece on a
rear face of the second lining wall 19. This also forms a pressing
force or pretensioning force formed in the widthwise direction
according to the arrow P, which presses the first lining wall 18
onto the first profile part 26.
[0074] FIG. 7 shows a further top view, similar to the views in
FIG. 5 and FIG. 6, of a further exemplary embodiment. In this
embodiment the first lining wall 18 is configured on its side
facing the second lining wall 19 in the same way as the embodiments
in FIG. 2 and FIG. 3, so that the hollow holder 34 is configured in
the manner of a groove or slot here. The two holder walls, which
delimit this hollow holder, are thus not elastic and not deformable
here in particular. Provision is therefore made in the present
embodiment for an elastically deformable stop 46 to be configured
on a rear face of the second lining wall 19, resting against a
front face of a holder wall 47 in a pretensioned manner. This again
generates a pressing force or pretensioning force in the direction
of the arrow P, so that the first lining wall 18 is again pressed
onto the first profile part 26.
[0075] FIG. 8 shows an enlarged diagram of the partial detail III
in FIG. 7.
[0076] This concrete elements, as described in relation to the
exemplary embodiments in FIG. 5 to FIG. 8, which generate such a
pretensioning force due to their elastically defined deformability,
in particular also allow the overlap produced in the widthwise
direction between the lining walls with play.
[0077] The descriptions given in relation to FIG. 5 to FIG. 8 also
apply to the overlap 22 preferably present between the second
lining wall 19 and the third lining wall 21, in particular in
conjunction with the second profile part 27.
