Household cooling appliance with an inner door wall being provided integrally with a suspension rib

The invention relates to a household cooling appliance with a door, the door comprising an inner door wall being provided integrally with a suspension rib for a door tray.

From the KR 2013 0015988 a household cooling appliance is known that has a door device comprising two doors. The doors are pivotable about a common axis, wherein they can be pivoted independently of each other as well as pivoted jointly. In the rear door a storage compartment is formed, which is closable by the front door. The entire door device closes a receptacle for food items that is separate from the storage compartment of the door device and is a cooling compartment. On an inner side of the front door, which faces the rear door, door trays are arranged. Furthermore, door trays are arranged on the rear door. The second door is bounded towards the rear by a wall that is transparent and in turn comprises a pivotable flap element itself.

In the known prior art an inner door wall is formed as pivotable, transparent sheet, on which however no further components are arranged.

Moreover, it is also known that an inner door wall can comprise vertically oriented door pillars, at which door trays can be attached. Such door pillars, however, are configured to be relatively massive and large so that they also require corresponding construction space. Moreover it is there only facilitated that on two opposite door pillars extending in parallel to each other in the vertical direction an attachment of a door tray is rendered possible so that invariably two such door pillars must be present. Since to such spaces commonly also several door trays are to be attached, these door pillars must also be dimensioned to be relatively large in order to allow for corresponding holders.

Door trays are known in multiple embodiments. For instance, it is known that a door tray viewed per se is configured as troughlike body, into which food items can be placed. Equally, it is known that door trays are formed as compartments of several components, wherein here a bottom is given, upon which the food items can be put. In these embodiments it may also be envisaged that there is no body that is troughlike, when viewed as such, and comprises side walls that extend directly from the bottom and reach upward, but rather between a bottom and a further component bounding the volume space of the door tray a slot is formed. This further bounding component can form a front wall of the door tray and is connected with the further components of the door tray. Such components of this further component, however, are limited with regard to permanent position security as well as with regard to mechanical load capacity.

It is an object of the present invention to provide a household cooling appliance, which is of a compact set-up, whilst still allowing for a simple attachment of a door tray, wherein the design of the inner door wall should comprise a reduced number of components.

The invention relates to a household cooling appliance with a door, the door comprising an inner door wall being provided integrally with a suspension rib for a door tray, wherein the suspension rib is oriented in the width direction of the inner door wall.

The suspension rib is formed for suspending the door tray. The suspension rib is oriented in the width direction of the inner door wall and thus extends in the horizontal direction. The suspension rip may extend in a width direction of the inner door wall over at least 30 %, or at least 50 %, or at least 70 %, or at least 80 % or at least 90 % of the overall extension of the inner door wall in width direction.

By providing the inner door wall integrally with the suspension rib, the suspension rib is formed as one piece with at least a portion of the inner door wall or with the complete inner door wall. For example, the inner door wall including the suspension rib can be formed as a single plastic injection part.

The inner door wall may have a planar wall element, which is formed as a single piece with the inner door wall. The suspension rib may be formed on this planar wall element. The planar wall element may constitute a main extension plane of the inner door wall.

By such a design a household cooling appliance with a reduced number of components is made possible, wherein the inner door wall integrally exhibits the functionality of the suspension rib. By such a single piece design moreover the required mounting effort is minimized. In particular the position of the suspension rib is also achieved to remain permanently consistent on the inner door wall.

According to an embodiment, the inner door wall is formed as a single piece and thus the entire inner door wall is manufactured as single component.

According to an embodiment, the suspension rib comprises a hole or breakthrough or opening, so that the door tray in the suspended state projects through the inner door wall. The hole, breakthrough or opening may be formed as a slit and the slit may extend horizontally.

According to an embodiment, the suspension rib is created as plateau that is elevated relative to a wall element on which the suspension rib is formed. The plateau can be formed as a rectangle. The suspension rib thus does not extend only within the plane of the wall element, but is configured as component that is elevated relative to it. By this design, the door tray can be attached in a simple and still purposeful way. Moreover, by such design the suspension rib is also a component that is stable in itself and is integrated within this planar wall element so that. Thus, it can securely absorb the retention forces and weight forces generated by the door tray and is not deformed in an undesired way. In particular, the plateau by being elevated relative to the wall element extends out of the wall element. In particular, the plateau extends towards a compartment for food items, which is formed in a housing of the household cooling appliance, in a closed position of the door.

The shape of this suspension rib designed as plateau thus can also be designed as pedestal or base. The plateau is configured in such a way that it comprises a plane plateau front wall, which thus extends in a plane parallel to the plane of the wall element of the inner door wall, which is formed by the height direction and the width direction.

The shape of the suspension rib as elevated plateau may be designed in such a way that from this plateau front wall narrow plateau edges start, which extend in the depth direction or essentially in the depth direction and end in the remaining surface area of the wall element. In particular, it is envisaged that in the depth direction of the inner door wall this plateau has a height that is smaller than 3 cm, in particular a height of between 0,5 cm and 3 cm. This means that this plateau viewed in the depth direction is relatively low so that it does not use up any undesired construction space and thus does not protrude undesirably far from the surface of the wall element. Nevertheless also in the case of such small plateau edges it is rendered possible to suspend the door tray from it in a secure and reliable way.

According to an embodiment, the suspension rib has a top plateau edge, on which a suspension slot for suspending the door tray is formed. The top plateau edge thus, viewed in the height direction, preferably is the top end of the suspension rib. This top plateau edge extends in the width direction of the inner door wall and thus in the horizontal direction. Therefore, the suspension slot, viewed in the height direction, is open toward the top and extends fully in the width direction. Thereby accessibility is simple and attachment of the door tray also made possible in a user-friendly way. According to an embodiment, there are two, three or several slots formed on the top plateau edge.

According to an embodiment, the suspension slot is configured as a breach in the wall element so that the door tray in the suspended state projects through the wall element. This breach, which thus also represents a slot-like hole or opening or breakthrough in the wall element, allows for a particularly compact set-up of the inner door wall in the depth direction. Thereby the system is also set up as compact as possible from an inner door wall and a door tray, in particular in this depth direction. Moreover by this design also an as simple as possible geometry of the suspension rib is facilitated and still a mechanically secure and stable suspension of the door tray achieved. In the suspended state the door tray thus extends on both sides of this planar wall element. For attachment of the door tray thus a particularly flat construction concept of the inner door wall is facilitated.

According to an embodiment, the suspension slot only in portions extends across the length of the top plateau edge. Thereby, the stability of the suspension rib, in particular at this top plateau edge is not restricted. The top plateau edge thus at least in portions also additionally ends in the plateau front wall, on the one hand, and the planar wall element, on the other hand, so that a tearing off of the suspension rib from the planar wall element is prevented, in particular when a door tray is suspended from the suspension slot. According to an embodiment, the suspension rib comprises lateral plateau edges and a bottom plateau edge, which are formed without slots, i.e. are directly connected to the planar wall element. In particular, the suspension rib can have two lateral plateau edges opposing each other and the bottom plateau edge can be positioned (in a width direction) between both lateral plateau edges. The lateral plateau edges can be connected to the bottom plateau edge. This means that the suspension rib at the, viewed in the height direction, vertical edges via one plateau each ends directly in the planar wall element and additionally also via a in the height direction lower plateau edge extending in the width direction ends in the planar wall element. Thereby, by these two lateral plateau edges and the lower plateau edge a U-shaped overall edge is formed, which allows for a particularly robust structure of the suspension rib. In particular, the mechanically stable shape design and connection to the planar wall element is achieved thereby. Moreover, by this uninterrupted design of the plateau edges it is also facilitated that undesired gases or liquids or other contaminations cannot find their way through these plateau edges and get behind the inner door wall.

According to an embodiment, the plateau is of a single wall design so that a rear side of the plateau forms a partial portion of a rear side of the planar wall element. Both in the area outside the suspension rib and in the area of this suspension rib the inner door wall thus in each case is of a merely single wall design. Thereby a particularly thin inner door wall is facilitated, which, however, integrated provides a very advantageous coupling option for the door tray.

According to an embodiment, the suspension rib on a rear side comprises a multitude of couple bars, which are integrally formed with the suspension rib and are configured to project from the rear side. A stiffening structure for the suspension rib, in particular of a plateau front wall of the suspension rib can be generated. Furthermore, a stable coupling with the door tray is facilitated. Due to the fact that these couple bars represent a thicker portion of the suspension rib beyond the thickness of the plateau front wall the attachment of the door tray is improved. The suspension rib in this connection is increased in thickness, whereby the suspension forces of the door tray can be received better.

According to an embodiment, the couple bars are configured to be a truss structure. The above-named advantages thereby become particularly evident. According to an embodiment, a first couple bar, viewed in the height direction of the inner door wall, is formed at a first height level on the rear side of the suspension rib, and a second couple bar is formed at a second height level that is lower relative thereto on the rear side of the suspension rib. The first couple bar extends with a first length away from the rear side. The second couple bar extends with a second length that is larger than the first length away from the rear side. In particular, the couple bars are oriented at an angle of 90° relative to the rear side. The lengths of the two couple bars are measured in a direction perpendicular to the rear side of the suspension rib. By such a different length design of the couple bars the attaching of the door tray is improved. In that the door tray comprises an at least in portions elastically deformable suspension element, by this design of the couple bars a particularly stable coupling, in particular jamming or bracing can be achieved. Thereby a particularly stable and securely positioned fitting of the door tray on the suspension rib is facilitated. By the weight forces upon suspension of the door tray this jamming or bracingwith the couple bars is facilitated and this then jammed or bracing state advantageously maintained.

According to an embodiment, the couple bars are configured as jamming or bracing structure. Thereby a jamming or bracing of the door tray is facilitated and a particularly secure retention of the door tray on the suspension rib achieved.

According to an embodiment, the inner door wall is configured to be troughlike and the wall element forms a trough bottom. For forming the trough shape of the inner door wall side walls end in this trough bottom. In at least one of these side walls ventilation openings or ventilation slots are formed.

According to an embodiment, a clearance or gap or channel is formed behind the inner door wall. In particular, the inner door wall may not be in contact with thermal insulation material, e.g. not in contact with polyurethane foam. Air can flow through that clearance streaming along a rear surface of the inner door wall and thus through the wall. In this case the cooling characteristics can be improved and condensation at the inner door wall be prevented. According to an embodiment, the inner door wall comprises a suspension hook for suspending the inner door wall on a support structure of the door. The suspension hook may be integrally formed with the inner door wall.

The inner door wall may comprise a multitude of suspension hooks, in particular at least two, preferably at least four, in particular at least six such suspension hooks. These suspension hooks can be arranged in pairs at equal height level. The suspension hooks can be integrated at opposite carrier bars that are configured at free edges the inner door wall.

According to an embodiment, the household cooling appliance comprises a door tray connected to the suspension rib. The door tray can be connected merely to the inner door wall, e.g. merely to the suspension rib. In particular, the door tray may contact only the inner door wall, in particular the door tray may contact only the suspension rib of the inner door wall.

According to an embodiment, the door tray on its rear wall has a suspension element. The suspension element can be formed integrally at the door tray, e.g. form a single piece with it. This suspension element, viewed in the height direction, can be inserted from the top into a suspension slot of the suspension rib so that the suspension element engages behind the wall element. This also means that this suspension element contacts a rear side of the inner door wall.

The suspension element can be designed as rooflike bar, which in the crosssection has an L-shape. A roof leg can be oriented in the depth direction and a further leg of the suspension element can extend therefrom oriented in the height direction with respect to the shape of this component. The suspension element can be formed as a rib. By this suspension element in its specific form and the rear wall of the door tray a notchlike or groovelike structure is created. The leg oriented in the height direction of the suspension element can be stuck through the suspension slot and contacts the rear side of the inner door wall, in particular the preferably present couple bars. The suspension rib then extends into this groovelike receiving space between the rear wall and the suspension element. Thus, a clamping effect between the rear wall of the door tray and the leg of the suspension element oriented in the height direction is produced. In particular, this suspension element is elastically deformable so that the clamping effect or the jamming effect of the suspension rib is achieved.

According to an embodiment, the door tray on its rear wall comprises distance bars which project towards the inner door wall. These distance bars can be integrally formed and thus manufactured as a single piece with the rear wall of the door tray. These distance bars can (in particular in a loaded condition of the door tray) contact surface areas formed adjacent to the suspension rib on the rear side of inner door wall, e.g. on the wall element, when the door tray is arranged in its mounted end position. By these distance bars the door tray is arranged in a supporting manner on the front side of the inner door wall, e.g. on the front side of the wall element. For example, the distance bars are designed in such a way that, viewed in the width direction, these distance bars contact the then extending surface of the front side of the inner door wall or the wall element directly next to the suspension rib. The suspension rib can have a width that in particular is also insertable to fit precisely into the width between the distance bars of the door tray.

According to an embodiment, the inner door wall is detachably connected to the door. In particular, the inner door wall can be connected to the door in a form-fit and/or force-fit fashion. In this way, the inner door wall can be removed for the purpose of servicing or cleaning. The cover may be releasable only by using tools.

According to an embodiment, the inner door wall is stationary coupled to the door. In particular, the inner door wall and the door may be permanently motion-coupled, that is when opening or closing the door the inner door wall will be moved along with the door. The inner door wall may therefore in particular not be movable relatively to the door.

According to an embodiment, the inner door wall is provided integrally with two, three or several suspension ribs. Each suspension rib can be designed as described with respect to the suspension rib. Two suspension ribs can be positioned at different height levels, i.e. one being positioned vertically above the other one. The suspension ribs can extend horizontally over the same length. The suspension ribs may in particular be parallel with respect to each other. The household cooling appliance can be provided with a compartment for food items, which is formed in a housing of the household cooling appliance. The compartment can be a cooling compartment or a freezer compartment. The door can be pivotably arranged on the housing so that the compartment is closable by the door at the front side. In the closed state of the door the inner door wall faces the compartment .

The household cooling appliance can comprise at least two separate compartments for food items, one of which may be a cooling compartment and the other a freezer compartment. It may be envisaged that these compartments are configured to be one above the other in the height direction of the household cooling appliance. For instance it may be envisaged that the top compartment is closable by two separate doors, which are pivotable about separate vertical axes, wherein the vertical axes extend in parallel to each other, however, are arranged at opposite sides of the housing, viewed in the width direction. These two doors for closing the compartment are pivotable independently of each other and, viewed in the width direction, are arranged adjacent to each other without overlapping. In the height direction these two doors are arranged at the same height level. In the closed state of the two doors they extend in one plane relative to each other that extends through the width direction and the height direction without overlapping.

The household cooling appliance additionally or instead can also exhibit a door device, which comprises an inner door and an outer door that is separate therefrom. The outer door is pivotably arranged with respect to the inner door. The inner door in the closed state at the front side is covered by the outer door at least in portions. In a coupled state of the two doors the outer door is motion-coupled with the inner door and these two doors then are jointly pivotable. In the inner door a storage space for food items is formed, which at the front side has an access opening that thus, viewed in the depth direction of the door device, is open towards the front. This access opening and thus also the storage space are closeable at the front side through the outer door. The door according to the present invention can in particular form the inner door of this door device and thus this inner door is provided with the inner door wall according to the invention.

According to an embodiment, the a vertical extension of the outer door and a vertical extension of the inner door as well as a horizontal extension in width direction of the outer door and a horizontal extension in width direction of the inner are substantially the same. “Substantially the same” in this context means, that a difference of an extension (vertical or horizontal) of the inner door with respect to the corresponding extension of the outer door is less than 25 %, less than 15 %, less than 10 % or less than 5 % in view of the respective extension of the outer door.

According to an embodiment, the outer door is substantially flat.“Substantially flat” in this context means that a vertical extension of the outer door and a horizontal extension in width direction of the outer door are each at least 5 times, or at least 10 times larger than a horizontal extension of the outer door in depth direction. In particular, there may be no door trays attached to the outer door.

According to an embodiment, the outer door is transparent at least in portions. In this way, goods to be stored in the storage space can be seen, even in case the outer door is closed. In particular, the outer door can comprise at least one viewing pane. The viewing pane, or window, can comprise a glass plate. In particular, the viewing pane can comprise an insulation glass. The insulation glass may consist of two, three or more glass panels which are positioned in depth direction with a distance to each other. Between the glass panels an insulation medium, e.g. inert gas, or a vacuum may exist. The viewing pane may be surrounded by a frame. The viewing pane may represent at least 50 %, or at least 75 %, or at least 80 % or at least 90 % of a visible front surface of the outer door.

In Fig. 1 in a schematic view an embodiment of a household cooling appliance 1 is shown, which for instance can be a cooling device or a freezer device or a fridge-freezer combination device. A household cooling appliance 1 , which is configured for storing and preserving food items, comprises a housing 2, in which at least one compartment 3 for food items is formed. The compartment 3 here is preferably a cooling compartment. Moreover, the household cooling appliance 1 comprises a door 4, which is pivotably arranged on the housing 2. The door 4 is configured for closing the compartment 3 on the front side.

In the case of the embodiment shown here, the compartment 3 is also closed by a further separate door, which is arranged in the width direction (x direction) adjacent to the door 4 and in the height direction (y direction) at the same height thereto. This further door in the embodiment is a door device 5. It is composed of at least two separate doors. The door device 5 comprises a storage space 11 , which is formed between the doors. In the storage space 11 at least one door tray 6 is formed, which in particular is configured for receiving bottles.

Moreover the household cooling appliance 1 comprises a further compartment 7 for food items, which is separate therefrom and can be a freezer compartment. The further compartment 7 is closable by a door 8 that is separate therefrom. This door 8 can be a front wall of a drawer, which can be pushed in and drawn out in the linear direction and thus in the depth direction (z-di recti on). In the closed state the doors 4 and 8 as well as the door device 5 are arranged in the same plane relative to each other and represent front side visible components or outer components of the household cooling appliance 1.

The doors 4 and 8 as well as the door device 5 are operable independently of each other. For accessing the compartment 3 the door 4 and the door device 5 can be opened or only one of the two components. The door 4 and the door device 5 each are pivotable about vertical axes.

Also an embodiment of a household cooling appliance 1 is envisaged, in which only the compartment 3 is present. Same can then also be closed by the door 4 and the door device 5. In a further embodiment it may also be envisaged that then one compartment 3 is only closed by a door device 5 and the door 4 is not present. Equally, an embodiment with the compartments 3 and 7 can be envisaged, in which in contrast to Fig. 1 the compartment 3 is closable only by the door device 5.

This door device 5 comprises, as this is also shown in Fig. 2, in particular a first door 9 and moreover a outer door 10 thereto. The two doors 9 and 10 each are individual objective components, which in particular are pivotable about a common vertical axis. The two doors 9 and 10 can be pivoted also independently of each other and thus individually. The outer door 10 in this connection represents the front side component and in the closed state covers the first door 9 that lies behind it in the depth direction. If the two doors 9 and 10 are coupled with each other they are also in this regard motion-coupled. This means that the entire door device 5 can then be jointly pivoted about a single vertical axis. Thereby, access is also provided to the compartment 3. If, on the other hand, only the front side outer door 10 of this door device 5 is activated and thus pivoted, access to the storage space 11 can be achieved. This storage space 11 thus is formed in the door device 5 itself. It may for instance be configured as bottle storage space. Thus this storage space 11 is arranged between the first door 9 and the outer door 10 and thus in the closed state of the door device 5 is bounded by the two doors 9 and 10. The storage space 11 is open towards the front so that it is accessible from the front when the outer door 10 is open. This may be achieved in both cases, when the first door 9 is closed and when the first door 9 is also open.

As can be moreover seen in Fig. 3, which is a perspective horizontal sectional view, the storage space 11 in an advantageous embodiment is bounded by a separate insert 12 at least laterally, towards the back, towards the top, and towards the bottom. This insert 12 therefore is of a troughlike design. It is shown in Fig. 3, which is a sectional perspective view, in which the sectional plane is in the horizontal plane and thus in x-z plane, with a bottom advantageously present lower door tray 6. The door tray 6 is integrated with partial components in the storage space 11.

Moreover, in Fig. 3 it can also be seen that on an inner side 13 of the first door 9 that faces the compartment 3 an in this respect further complete separate door tray 14 is arranged. This further door tray 14 can be a common door tray and in the closed state of the first door 9 is not accessible from the outside and thus the front side.

In Fig. 3 the outer door 10 is shown in the opened state so that at the front side access to the storage space 11 is facilitated. The first door 9, however, remains further closed so that access to the compartment 3 is denied. As can be seen here, the outer door 10 has a design that is transparent at least in portions. For this purpose in the shown embodiment at least one viewing pane 15 is provided, through which in the closed state of the door 10 it can be looked. The outer door 10 in this connection preferably also comprises a frame 16, which circumferentially encloses this at least one viewing pane 15, preferably a pane package, which can also be insulation glass.

In Fig. 4 in a perspective vertical sectional view the household cooling appliance 1 according to Fig. 1 in the area of the door device 5 is shown. Here a state is shown, in which also the outer door 10 is shown in the closed state. The door device 5, which is also designed as a door-to-door system, thus also facilitates that in the closed state of the first door 9 the outer door 10 can be opened and thus the sole access is only granted to the storage space 11. If access to the compartment 3 is achieved, the entire door device 5 and thus the then motion-coupled doors 9 and 10 are pivoted so that then also access to these interior door trays 14 is given.

As can also be seen in the representations in Fig. 2 to Fig. 4, the storage space 11 has a front side access opening 17, which is closable by the outer door 10.

The door device 5, as can equally be seen in Fig. 2 to Fig. 4, comprises a troughlike wall body 18. This troughlike wall body is configured in particular as a single piece. It is preferably formed from plastic. It is in particular an injection-moulded component. In particular the insert 12 is formed by the wall body 18.

The wall body 18, which can also be referred to as body 19, is vertically oriented. This means that it is positioned upright in its trough shape and the trough opening is oriented towards the front. The wall opening is also defined by the access opening 17.

This wall body 18 has a rear wall 20, which also represents a trough bottom of this wall shape. This rear wall 20 is vertically oriented and thus extends in the x-y plane.

Moreover the wall body 18 on this rear wall 20 has side walls 21 and 22 ending in it, which in particular are vertically oriented side walls. Moreover this wall body has a bottom horizontal side wall 23 and moreover has a top horizontal side wall 24. This wall body 18 is configured as insert 12, which bounds the storage space 11 thus towards the back, towards the side, towards the bottom, and towards the top.

The door device 5 moreover comprises a cover 25 that is separate from the wall body 18. This separate cover 25 is preferably formed as a single piece, in particular from plastic. The cover 25 in the embodiment is equally designed to be troughlike. It comprises a rear wall, which is formed as trough bottom 26. The cover 25 is designed in such a way that it covers the wall body 18, viewed in the depth direction (z direction), towards the back, in particular fully covers it. Towards the compartment 3 the wall body 18 thus is fully covered by the cover 25.

As can also be seen in Fig. 3 and Fig. 4, the wall body 18, viewed in the depth direction, plunges into the volume of the troughlike cover 25. Nevertheless, the rear wall 20 and the trough bottom 26, which is equally configured as rear wall, are arranged spaced apart from each other.

The cover 25 in the embodiment also represents an inner door wall 27, which covers the first door 9 towards the back and thus is a rear end part. In particular is this inner door wall 27 thus also a rear visible component of the first door 9. In the shown embodiment this inner door wall 27, which represents the cover 25 for the wall body 18, is also a rear end part of the door device 5.

The cover 25 comprises side walls 28 and 29 ending in the trough bottom 26, which are vertical side walls. The inner side 13 (facing the compartment 3) is the inner side of the trough bottom 26. Thus, on the cover 25 the separate door tray 14 is attached.

The door tray 14 is arranged on the side of the door device 5 facing away from the storage space 11 and thus external to the storage space 11. In the closed state of the first door 9 the door tray 14 is arranged to face the compartment 3 and extends in particular also into the compartment 3. In particular the door tray 14 thus is exposed to the storage conditions as they are prevailing in the compartment 3, if at least the first door 9 is closed. The cover 25 thus is arranged on the side of the wall body 18 opposite the access opening 17. This cover 25 covers the body 18 on the side facing away from the outer door 10.

As can equally be seen in Fig. 2 to Fig. 4, the wall body 18 and the cover 25, which is separate therefrom, are components of the first door 9. In particular the cover 25 and/or the wall body 18 is arranged on a support structure 30 of the door device 5, in particular the first door 9. The support structure 30 is preferably a frame. In particular the frame is configured to be circumferentially closed.

Moreover, on the wall body 18 in the storage space 11 a further, separate door tray 88 is arranged.

In Fig. 5 in a perspective view an embodiment of the cover 25 is shown. The cover 25, as it is already set out in the above, can advantageously be configured as inner door wall 27 for a door, here in particular the first door 9.

On the vertically oriented side walls 28 and 29, which are situated opposite in the height direction, a plurality of suspension hooks 31 , 32, 33, 34, 35, and 36 are formed, here in particular six. The suspension hooks 31 to 36 are integrated into the side walls 28 and 29. Preferably, at least two such suspension hooks 31 to 36 are present. In the embodiment shown here suspension hooks 31 to 36 are formed in pairs at the same height level. Advantageously, it is envisaged that the suspension hooks 31 to 36 are configured to project from the side walls 28 to 29. They are freely cantilevering and in this connection oriented to face away from the rear wall 20.

Advantageously, it is envisaged that on free vertical edges 37 and 38 of the side walls 28 and 29 carrier bars 39 and 40 are configured. The carrier bars 39 and 40 are designed as ribs and integrally formed with the side walls 28 and 29. On the carrier bars 39 and 40 projecting from the vertical edges 37 and 38 towards the front the suspension hooks 31 to 36 are integrally formed.

With the suspension hooks 31 to 36 the cover 25 is suspended from a component of the door device 5. In particular here a suspension from the top from the support structure 30 is envisaged. This support structure 30, as already mentioned in the above, at least in portions is configured as at least U-shaped carrier frame, preferably circumferentially closed carrier frame.

Moreover, it can also be seen that the cover 25, which here in the shown embodiment is troughlike, comprises a further bottom side wall 41 and a further top side wall 42. By the side walls 28, 29, 41 und 42 thus also the trough is configured to be circumferentially closed. In the bottom side wall 41 , which is oriented in the width direction, in an advantageous embodiment ventilation openings 43 are formed. These ventilation openings 43 are here configured to be ventilation slots. Advantageously, it is also envisaged that, in the, viewed in the height direction, top side wall 42 equally ventilation openings 44 are formed, which are configured as ventilation slots.

It may be envisaged that the ventilation openings 43 and 44 can additionally be connected with crossbars that are not shown here. These crossbars 45 are shown in an exemplary way in Fig. 6.

Moreover, it is preferably shown that the ventilation openings 43 and 44 are bounded by slanted walls so that the respective depth (viewed perpendicular to the sidewall 41 , 42) of the ventilation openings is enlarged. The depth measured in the direction of the current then is not only given by the wall thickness of a side wall 41 , 42, but by the bounding walls, which in this respect are extended.

By these ventilation openings 43, 44 a clearance 46 (Fig. 3 and Fig. 4), which is formed between the cover 25, here in particular air flows through the inner door wall 27, and the wall body 18, in particular the body 19. Thereby a condensation in this clearance 46 can be avoided. Moreover by such an air flow in the clearance 46 an individual admission of temperature can be effected.

Advantageously, the cover 25 and thus in particular the inner door wall 27 is integrally formed, in particular from plastic. Here an injection-moulded component can be formed. Preferably, this injection-moulded component can be manufactured by a cascade injection-moulding. In an advantageous embodiment it is envisaged that the wall body 18 is attached in a non- destructively releasable way on the support structure 30. Preferably, here at least one screw connection is envisaged. Advantageously, it is envisaged that the cover 25 and thus in particular also the inner door wall 27 is attached in a non-destructively releasable way directly on the wall body 18. Here at least one screw connection can be provided. In particular it is envisaged that the cover 25 is suspended from the support structure 30 and additionally the cover 25 is screwed onto the wall body 18.

Preferably, it is envisaged that the wall body 18, viewed in the depth direction (z direction) of the door device 5, at least in portions is arranged to plunge into the cover 25, as it can be seen in Fig. 3 and Fig. 4. The clearance 46 is in particular also formed between the rear wall 20 of the wall body 18 and also between a rear wall of the cover 25. In the embodiment this rear wall is formed by the trough bottom 26.

In particular it is envisaged that the cover 25 and thus in particular also the inner door wall 27 comprises an integrally formed suspension rib 47, as it is shown in Fig. 7. The suspension rib 47 thus integrally manufactured with the inner door wall 27 is configured for suspending a door tray that is separate therefrom, in particular the door tray 14. As can be seen in Fig. 7, by the wall bottom 26, which here represents an embodiment for a wall element 48 of the inner door wall 27, this suspension rib 47 is formed as a single piece with it. This wall element 48 is oriented in the vertical direction and in the x-y plane.

In the representation in Fig. 7 it can be seen that this suspension rib 47 is oriented in the width direction and represents a plateau 49 that is elevated relative to the wall element 48. This plateau 49 thus can also be referred to as pedestal or base. This plateau 49 has a plane plateau front wall 50. This extends advantageously in a plane parallel to the plane of the wall element 48.

By narrow plateau edges, namely in particular a bottom plateau edge 51 , lateral plateau edges 52 and 53 and a top plateau edge 54, the elevated structure is formed and the connection to the wall element 48 achieved. Viewed in a direction perpendicular to the plane of the wall element 48 and thus in the depth direction, the plateau 49 preferably has a height smaller than 3 cm, in particular between 1 cm and 3 cm. The, viewed in the height direction, top plateau edge 54, which extends in the width direction, has a suspension slot 55. In this suspension slot 55, which is fully pass-through and thus is also configured as a slot hole, the door tray 14 can be suspended from the top. This suspension slot 55 thus is open towards the top, viewed in the height direction. The suspension slot 55 thus is also a breach in the wall element 48 so that the door tray 14 in the suspended state projects through the wall element 48. The door tray 14 thus projects through the wall element 48 and is arranged in the mounted state on both sides of the wall element 48.

As can be seen in Fig. 7, the suspension slot 55 only in portions extends beyond the length of the top plateau edge 54 dimensioned in the width direction.

Preferably, it is envisaged that the lateral plateau edges 52 and 53 are configured to be of an uninterrupted design. In particular also the bottom plateau edge 51 is of an uninterrupted design. The lateral plateau edges 52 and 53 directly end in the bottom plateau edge 51 so that here a U-shaped plateau edge construct is formed, which is designed to be uninterrupted and without a slot.

The plateau 49 is of a single-wall design so that a rear side 56 (Fig. 8) of the plateau 49 forms a partial area of a rear wall of the wall element 48.

The suspension rib 47 on its rear side 56 preferably comprises a multitude of couple bars 58 that are formed as a single piece with the suspension rib 47. This can be seen in the perspective sectional view in Fig. 8. In Fig. 9 in this connection a view of the couple bars 58 is shown, which preferably is configured as truss structure 57.

As can be seen in Fig. 8 and Fig. 9, these couple bars 58 are configured to project from the rear side 56. It may be envisaged, as this is shown in Fig. 8, that in a direction perpendicular to this rear side 56 the couple bars 58 have different dimensions. For instance a couple bar 58 that is further spaced apart from the suspension rib 55 towards the bottom can extend with a larger length away from the rear side 56 than a couple bar 58 arranged in the height direction above it. By the couple bars 58, in particular if they have different lengths in a direction perpendicular to the rear side 56, also a clamping structure or jamming structure for the door tray 14 can be formed. Thereby upon suspending also a clamping or jamming holding of the door tray 14 to the suspension rib 47 can be facilitated. Moreover, by the couple bars 58 also a stiffening of the suspension rib 47 is achieved.

Moreover in Fig. 8 it can also be seen that the suspension slot 55 is formed in a direction perpendicular to the wall element 48 not across the entire dimensions of the top plateau edge 54, but is narrower. Thereby a transition 59 is formed, which is not present as narrow, sharp edge, but as rounded roof bar.

In Figs. 5, 6, and 9 also an arrangement 60 is shown, which comprises the inner door wall 27 and the door tray 14. An exemplary door tray 14, as it can be installed on the inner door wall 27, is shown in Fig. 10. The door tray 14 on a rear wall 61 comprises a suspension element 62 that is formed as a single piece with it. This is here configured to be rib-like or strip-like. It extends in an L-shape from the rear wall. It comprises a roof bar 63 and a leg 64 that is vertically oriented relatively thereto. As can be seen in Fig. 9, the vertical leg 64 extends through the suspension rib 55 from the top. With this leg 64 thus the door tray 14 engages behind the inner door wall 27. The roof bar 63 rests on the top plateau edge 54, in particular the transition 59 and thus also the suspension rib 47 from the top. Thus the leg 64 is arranged spaced apart from the rear wall 61.

Advantageously, it is also envisaged that the door tray 14 comprises distance bars 65 and 66. These extend to project from the rear wall 61. These distance bars 65 and 66 in the width direction are spaced from each other in such a way that they contact the wall element 48 laterally of the suspension rib 47 in the mounted state of the door tray 14. In particular here essentially, viewed in the width direction, a precisely fitting receiving of the suspension rib 47 is facilitated. Thereby the fit of the door tray 14 on the inner door wall 27 in the suspended state is improved. In particular a slipping in the width direction in an advantageous embodiment is thereby avoided. Additionally or instead, it may also be envisaged that the leg 64 has a width that corresponds to the width of the suspension slot 55.

The door tray 14 is formed as a single piece with the suspension element 62 and/or the distance bars 65 and 66. The arrangement 60 in an advantageous embodiment can be integral component of a door of a household cooling appliance 1. In the shown embodiment it is integral component of the door 9. In particular same is integral part of the door device 5.

In Fig. 11 in a perspective sectional view the arrangement 60 is shown. It can be seen here how the vertical leg 64 is inserted through the suspension slot 55 from the top and engages the wall element 48 from behind. In particular here a coupling with the couple bars 58 is shown so that preferably a clamping effect is achieved. Moreover it can also be seen that the rear wall 61 contacts the plateau front wall 50 laminar. Advantageously, the suspension rib 47, viewed in the height direction, is dimensioned in such a way that it has the height of the rear wall 61 or essentially this height. In the mounted state of the door tray 14 the suspension rib 47 thus is fully covered by the door tray 14 at the front side.

In Fig. 12 in an enlarged view a partial section from Fig. 11 is shown. The clamping attachment of the door tray 14 on the suspension rib 47 can be seen. By the leg 64 and the rear wall 61 a slot or a groove 67 is formed, into which then the plateau front wall 50 and the couple bars 58 plunge.

In Fig. 13 in a perspective view the wall body 18 is shown, which here forms a body 19 of a door tray. The troughlike wall body 18 at its top side wall 24 advantageously comprises ventilation openings 68. In particular it is also envisaged that at its bottom side wall 23 it additionally or instead equally comprises ventilation openings 69. By the bottom side wall 23, viewed in the height direction, a bottom is formed. This bottom advantageously is also the bottom of a door tray 71. The door tray 71 , as it is in particular configured in Fig. 13 and Fig. 14, which shows an enlarged partial view of Fig. 13, comprises the body 19, the bottom 70, side walls 21 and 22 as well as a front wall. The front wall 72 is here formed by a separate rib 73. The door tray 71 comprises a storage space 74, in particular for bottles. In the shown embodiment the door tray 71 thus is also formed by the wall body 18 and this separate rib 73. The door tray 71 thus is integrated with partial components into the door 9. Parts of the door tray 71 thus are multifunctional components, since they in addition to forming a storage space 74 also have at least one further function, in particular bound the storage space 11. In particular a partial volume of the storage space 11 is formed by the storage space 74. The rib 73 represents a board-like or beamlike element, which here is a straight, rectangular plate. This rib 73 then also extends into a plane. The rib 73, viewed in the height direction, is arranged spaced apart from the bottom 70 so that between the bottom 70 and the rib 73 an air gap 75 is formed.

The rib 73 is connected at its opposite ends with the side walls 21 and 22 and extends advantageously across the entire clear width between the side walls 21 and 22. This rib 73 can also be referred to as connection bar which extends between the sidewalls 21 and 22.

Advantageously this front wall 72, which is configured as rib 73, is fastened by at least one, here preferably two separate holding brackets 76 and 77, as this is shown in particular in the exploded view in Fig. 14. The single-piece holding brackets 76 and 77 are here of an L-shaped design. As can be seen, the side wall 22 has a passage 78, which here is configured to be slot-like. It is fully circumferentially framed so that it is no passage that is open towards the front edge of the side wall 22. The holding bracket 77, which is explained in more detail in place of the further angle 76 of the same construction design, in the mounted state extends through this passage 78. It goes without saying that advantageously also the further side wall 21 comprises such passage, through which the further holding bracket 76 extends.

In the mounted state the holding bracket 77 extends on both sides of plate-like side wall 22. The holding bracket 77 comprises a first bracket element 79. This first bracket element 79 in the mounted state of the holding bracket 77 contacts an outer side 80 of the side wall 22. This outer side 80 is the side, which faces away from the opposite side wall 21 , and thus also faces away from the storage space 74. This first bracket element 79 contacts this surface 80 laminar.

The single-piece holding bracket 77 moreover comprises a second bracket element 81 , which ends in the first bracket element 79, in particular at an angle of 90°. In the mounted state this second bracket element 81 , which is oriented in the width direction, extends through the passage 78 and is coupled with the rib 73. The second bracket element 81 thus is a couple blade. As can be seen in Fig. 14, and in the enlarged view in Fig. 15 in more detail, at this outer side 80 a coupling structure 82 is formed. This coupling structure

82 here and thus in the embodiment comprises two differently shaped coupling elements

83 and 84, which are integrated into the outer side 80. In particular it is envisaged that in the first bracket element 79 a complementary counter coupling structure 85 is formed, as it can be seen in the enlarged view in Fig. 16. In the mounted state of the holding bracket 77, as this is shown in Fig. 16, the coupling structure 82 is coupled with the counter coupling structure 85. For this purpose the coupling elements 83 and 84 plunge into the corresponding counter coupling elements in the first bracket element 79. In particular the coupling elements 83 and 84 extend through the counter coupling elements of the counter coupling structure 85 that are configured as respective holes.

In Fig. 16 the mounted final state of the holding bracket 77 on the side wall 22 is shown. The second bracket element 81 extends through the passage 78. In this second bracket element 81 in an advantageous design at least one clamp element 86 is formed, in particular integrally formed therein. The clamp element 86 preferably is a spring element, which partly projects from the first bracket element 81.

Advantageously it is envisaged that the rib 73 at least partly is configured to comprise a hollow profile 87 (Fig. 19). In particular at the ends, which are envisaged for coupling with the holding brackets 76 and 77, these hollow profiles 87 are formed and open towards the side. Upon mounting the rib 73 the first bracket element 81 is inserted into the hollow profile 87, in particular the, in the height direction, central hollow profile 87. By the clamp element 86 a jamming in the hollow profile 87 is effected. In this regard in Fig. 17 in a perspective enlarged view the mounted final state of the rib 73 on the holding bracket 77 is shown. The second bracket element 81 plunges comprehensively into the hollow profile 87. The rib 73 then is arranged in such a way that advantageously, viewed in the depth direction, it is flush with the front edge of the side wall 22 as well as with the front edge of the side wall 21.

In Fig. 18 in a horizontal sectional view (sectional plane is the x-z plane) the design in Fig. 17 is shown. Here it can be seen, how the second bracket element 81 is plunged into the hollow profile and by the clamp element 86 a jamming therein is achieved.

In Fig. 19 a view of an end of the rib 73 is shown so that here the hollow profile 87, which is open at the end face, can be discerned. 5 Preferably, the rib 73, which is configured as front wall, is an extruded metal profile, in particular an extruded aluminum profile.
