Description

The invention relates to a household refrigeration appliance with a housing in which at least one first receiving space for food is formed, which space is delimited by the walls of an inner container. The domestic refrigeration appliance also includes a pull-out carriage that can be displaced linearly in the depth direction of this domestic refrigeration appliance and in a direction of movement relative to the housing and is arranged such that it can be pushed into and pulled out of the first receiving space. This pull-out trolley includes a door for closing the first accommodation space.

From the WO 2009/127696 A2 a refrigerator with a drawer is known. It is envisaged that a drawer-in-drawer system is formed. This means that a smaller drawer can be positioned within the volume of the larger drawer when the larger drawer is positioned in the extended state and the smaller drawer, which can then only be moved in this direction of displacement and thus in the depth direction of the household refrigeration appliance, can be moved via an opening on the rear wall of the larger one Drawer can be slid into the recording volume of the larger drawer.

In addition, from the DE 10 2008 040 609 A1 a refrigerator with a so-called apothecary pull-out is known. It is provided there that a carriage is provided in an interior space that can be retracted and pulled out in a straight line and has a door on which a plurality of shelves arranged at different heights are formed. However, these shelves are merely plate-like elements which, when they are coupled to the door, can only all be pulled out or pushed in together and moved in the same way with the door. When coupled to the door, the shelves are designed without any degree of freedom with respect to movement relative to one another. It can be provided that only some of these shelves are coupled to the door and can only then be pulled out or pushed in with the door, in which case the remaining shelves that are not coupled to the door are independent of this and are arranged to remain in the receiving space or interior . In this embodiment, the plate-like arrangement of the shelves allows lateral access to the respective levels, but access from above to a shelf arranged further below is not possible.

WO 2009/115277 A2 discloses an apparatus having a housing, a movable door panel and a back panel, the door panel and the back panel being spaced from each other and being movable together.

U.S. 1,835,847 A discloses an apparatus with a door, wherein a frame is coupled to the door such that when the door is pivoted open, the frame is pulled out.

JP H03 233 281 A discloses a device with a door panel and a shell arranged on the door panel and which can be pulled out together with the door panel.

DE 10 2013 111 734 A1 discloses a drawer for a refrigerator, in which at least one pull-out is arranged, which can be adjusted from a basic position in which it is arranged in the vertical direction above a loading level of the drawer by adjusting in a horizontal adjustment direction transverse to the pull-out direction into an adjustment position, in particular displaceable or pivotable, the pull-out being arranged at least partially to the side of the drawer in the adjustment position.

US 2006/0 218 958 A1 discloses a device with a door panel and a tray arranged on the door panel, which can be pulled out together with the door panel.

It is the object of the present invention to create a household refrigeration appliance in which a pull-out trolley is improved in terms of its loading options.

This object is achieved by a household refrigeration appliance according to claim 1.

A household refrigerating appliance according to the invention comprises a housing in which at least one first receiving space for food, delimited by walls of an inner container, is formed. The household refrigeration appliance also includes a pull-out trolley that can be pushed in and pulled out linearly in the depth direction of the household refrigeration appliance and relative to the housing in a direction of movement in this first receiving space. The pull-out trolley includes a door for closing the first accommodation space. The pull-out trolley also includes a storage shelf which is movement-coupled to the door with a front end facing the door. The storage shelf is thus also moved in corresponding directions when the pull-out trolley is moved linearly. An essential idea of the invention can be seen in the fact that the pull-out trolley has a rear wall that extends upwards from the storage shelf. With this configuration of the pull-out trolley, it is easy to accommodate different objects on the storage shelf take place. Since in this context the capacity of the pull-out trolley is limited at the front by the door and at the back by the rear wall, this linear displacement of the pull-out trolley in the depth direction of the household refrigeration appliance prevents objects placed on the storage shelf from falling down. This is then also particularly advantageous, since precisely when the pull-out trolley is pulled out, no objects can then fall backwards from the storage shelf into the first receiving space. A very user-friendly handling is also achieved by this design of the pull-out trolley. Nevertheless, the pull-out trolley is not restricted in terms of unrestricted viewing from above or unrestricted viewing from the side when pulled out. Both recognizing what is parked on the storage shelf and the accessibility for removing objects from the storage shelf, as well as equipping the storage shelf with objects is therefore possible without restrictions.

The rear wall is preferably a one-piece plate, which is thus designed as a solid part over its entire surface and throughout.

Provision is preferably made for the rear wall to be arranged parallel and at a distance from the door. This achieves the limitation of the storage volume at the front and rear, and the parallel and therefore also vertical arrangement of the rear wall and the door does not impede access to the storage shelf.

The storage shelf preferably extends in a horizontal plane that is spanned by the width direction and the depth direction of the household refrigeration appliance. For this purpose, the rear wall extends in particular in the direction perpendicular thereto, which is thus spanned in a plane which is defined by the width direction and the height direction of the household refrigeration appliance. The door is preferably also arranged oriented in such a vertical plane.

Provision is preferably made for the rear wall to be coupled to the movement of the pull-out carriage. Thus, the rear wall is also moved accordingly when the pull-out trolley is pulled out and when the pull-out trolley is pushed in. In the case of these movement guides, there is preferably no relative movement between the storage shelf and the rear wall.

According to the invention, it is provided that the rear wall, viewed in the depth direction of the household refrigeration appliance, can be displaced relative to the storage shelf. This is an advantageous embodiment in that the capacity of the pull-out trolley can be changed individually. As a result, individual objects that are placed on the storage shelf for storage in the first receiving space can also be better positioned, if necessary, and in particular can even be clamped between the rear wall and the door. This can be advantageous, for example, for very bulky foodstuffs that can easily move, for example roll, when the pull-out trolley moves relative to it. This can apply to specific types of vegetables and/or specific types of fruit, but also, for example, to chicken or the like. In addition, such a configuration is also advantageous when bottles are placed on the shelf.

It can be provided that in such an alternative configuration, in which the rear wall can be displaced relative to the storage shelf, different displacement positions of this rear wall can be locked. In this connection, discrete displacement positions can be provided, in which the rear wall can then be latched, for example. However, it is also possible for the rear wall to be continuously adjustable relative to the storage shelf. In this embodiment, too, the then individual displacement positions can be locked. Here, too, specific clamping devices or latching devices can then be provided.

In particular, it is also provided that the door of the pull-out trolley is designed to be transparent, at least in certain areas. For this purpose, it can preferably have a viewing window. With such a design, it is possible to look into the first receiving space even when the pull-out trolley is closed. This can be advantageous in that a user can see what is stored in the first storage space even when the pull-out trolley is closed. Extensive information on this is therefore obtained without having to pull out the pull-out trolley. This achieves a very energy-efficient mode of operation of the household refrigeration appliance, since no more cold escapes as the pull-out trolley is no longer required to be pulled out.

Provision is preferably made for the door of the pull-out trolley to be designed without handles on a front side. A handle that then protrudes forward and on which a user could hit is then avoided. In addition, especially in the case of designs in which the door of the pull-out trolley is to be made transparent, there is no longer a front handle in the way. The transparent area and thus the viewing window can therefore be designed to the maximum.

It is preferably provided that the door of the pull-out trolley is formed with a recessed grip on a vertical side edge, which thus represents a narrow edge adjoining at an angle on a front side. As a result, a handle for opening this door is designed in a very space-minimised manner and yet is easily and comprehensively accessible at all times. Provision can be made for the door of the pull-out trolley to have a recessed grip on a horizontal side edge in addition to or instead of this. This horizontal side edge can be formed at the top or bottom of the door.

The storage shelf is preferably made of real glass, at least in certain areas, in particular completely. Real glass is understood to mean all glasses that are not classified as plastic glasses. A floor made of real glass enables improved light propagation throughout the recording room through the floor. Furthermore, real glass also provides sufficient stability and solidity. This also prevents sagging when the floor is fully stocked with stored goods or containers.

Provision is preferably made for at least one sliding rail device to be arranged on the storage shelf, by means of which the relative displacement of the sliding trolley relative to the housing can be carried out. The rail extension device is preferably a telescopic rail with a fixed rail and at least one running rail.

Provision is made in a particularly advantageous manner for this telescopic rail device to be arranged lying flat with a rectangular cross-sectional geometry viewed in cross section and thus in a sectional plane perpendicular to the longitudinal axis of these rails of the telescopic rail device. This means that the longer sides of this rectangular cross-sectional shape extend in the horizontal direction and thus in the width direction of the household refrigeration appliance. This configuration achieves a very space-minimised and height-reduced arrangement of the telescopic rail device.

It can be provided that the rail extension device also has at least two such rail extensions, in particular in the form of telescopic rails.

However, provision can also be made for this rail extension device to be arranged upright, so that the longer sides of the exemplary cross-sectional geometry of the rails mentioned above are then oriented in the height direction and thus in the vertical direction of the household refrigeration appliance.

It is preferably provided that foodstuffs can be placed directly on the storage shelf and/or at least one trough-like food storage container can be set up. Such a trough-like food storage container can then be easily placed on the installation floor by a user and removed from it.

Preferably, the shelf is a plate that is designed as such over the entire surface and is solid.

In particular, the rear wall is also a solid plate.

The pull-out trolley preferably has only one storage shelf. Preferably, the shelf, in particular only the single shelf, opens out to a lower area, in particular a lower end, of the door, in particular also opening out to a lower end of the rear wall. This maximizes the storage volume, since virtually the entire height of the door is available for the front limitation and thus objects of corresponding height can be safely placed on the storage shelf. The pull-out trolley and thus the storage shelf is not covered by a cover from above in the extended state, so that this particular storage shelf is freely accessible.

Provision is preferably made for at least one second accommodation space for accommodating food to be formed in the housing, which is separate from the first food accommodation space and which can be closed by a further separate door.

In an advantageous embodiment it is provided that when the pull-out trolley is pushed in and the further door is in the closed state, a front door of the pull-out trolley and a further front door are arranged flush. As a result, the doors are arranged so that they do not protrude, so that there are no edges or the like that a user could hit.

Preferably, the other door is also designed without handles on its front side. In particular, a recessed grip is also formed on a vertical side edge and/or on a horizontal side edge in this further door.

Directions such as "widthwise", "heightwise", "depthwise", "top", "bottom", "front", "back", "front", "back", etc. refer to the one-to-one state conventional use placed household refrigeration appliance, the door is arranged for a viewer at the front and the back at the back.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

In 1 a domestic refrigeration appliance 1 is shown, which is designed as a combination fridge-freezer and is designed to accommodate and thus store and preserve food. The household refrigeration appliance 1 comprises a housing 2 in which an inner container is arranged, which has a first receiving space 4, which is, for example, a refrigerator, and a second receiving space 3, which is, for example, a freezer. The two receiving spaces 3 and 4 are separated from one another and can be closed by separate doors 5 and 6, respectively. In 1 Both receiving spaces 3 and 4 are shown in the respectively closed state by the doors 5 and 6.

The household refrigeration appliance 1 can also have a third separate storage space 7 for food, which can preferably also be closed by a separate door 8 of its own.

In the exemplary embodiment, the door 6 is part of a pull-out trolley 9 that can be pulled out and pushed back in in a straight direction with a linear movement in the depth direction and thus in the z-direction of the household refrigeration appliance 1 . In 1 the pull-out carriage 9 is shown in the fully inserted state.

As in 1 is also shown, the door 6 of the pull-out trolley 9 is designed without handles on a front side 10 .

In particular, it is provided that a recessed grip is formed on a vertical side edge 11 and/or on a vertical side edge 12 and/or on an upper horizontal side edge 13 and/or on a lower horizontal side edge 14, into which a user can reach with his fingers , in order to be able to pull out the pull-out trolley 9.

As can also be seen in the exemplary embodiment, the door 6 is designed with a viewing window 15 which here has a maximum size which corresponds to almost the entire area of the front side 10 . Through this viewing window 15 it is then possible to look into the first receiving space 4 even when the door 6 is closed and thus when the pull-out trolley 9 is completely pushed into the first receiving space 4 . In addition, it is provided that the front side 10 of the door 6 is flush with a front side 16 of the door 5 when the pull-out trolley 9 is in the inserted state when it is closed. In addition, it is also provided that a front side 17 of the optionally present door 8 is flush with the front side 10 when the door 8 is also closed.

In 2 shows the household refrigeration appliance 1 in a partial view, the pull-out trolley 9 being shown here in a fully extended state. Exemplary finger grips 18 and 19 are shown on vertical side edges 11 and 12 .

The pull-out trolley 9 also includes a storage shelf 20, which is preferably used as a Plate is formed. The storage shelf 20 is in particular made of real glass.

This storage shelf 20 is arranged in a horizontal plane and is connected to the door 6 at a lower end of the door 6 by a front end 20a. The single storage shelf 20 of the pull-out trolley 9 is thus coupled in movement to the door 6 so that it is moved into the first receiving space 4 when the pull-out trolley 9 is pulled out and pushed in.

The pull-out trolley 9 also includes a full-surface, plate-like rear wall 21. This plate-like rear wall 21 preferably extends over the entire width (extension in the x-direction) of the storage shelf 20. It is also oriented in the vertical direction and thus extends in the x-y Level. The rear wall 21 is parallel to the door 6 and spaced therefrom. If the rear wall 21 is stationary and therefore not displaceable relative to the storage shelf 20 in the z-direction, it is preferably arranged with a lower end opening out at a rear end 20b of the storage shelf 20 . In such an embodiment, the rear wall 21 can be formed in one piece with the storage shelf 20 . Viewed in the depth direction and thus in the z-direction, the rear wall 21 also delimits a receiving volume at the rear, which is delimited at the bottom by the storage shelf 20 and at the front by the door 6 .

In an alternative embodiment it can be provided that the rear wall 21 can be moved in the z-direction relative to the storage shelf 20 and thus a distance between the door 6 and the rear wall 21 can be changed. As a result, the size of the recording volume can be changed in the depth direction.

The rear wall 21 is also motion-coupled to the door 6 and the storage shelf 20, so that when the pull-out trolley 9 is pulled out, the rear wall 21 is also moved out and, correspondingly, when the pull-out trolley 9 is pushed in, the rear wall 21 is moved in again.

A slide-out device 22 is provided for guiding the movement of the slide-out carriage 9 relative to the housing 2 . In 3 an enlarged representation of an exemplary embodiment is shown for this purpose. The rail extension device 22 comprises at least one telescopic rail 23 which has a fixed rail 24 arranged in a stationary manner in a floor which delimits the first receiving space 4 and a running rail 25 coupled thereto and movable relative thereto. This running rail 25 is attached to an underside 26 of the storage shelf 20 . As shown in the illustration in 3 As can be seen, the rails 24 and 25, which are elongated or rectangular in cross-section, are arranged transversely in the embodiment shown, so that the rail extension device 22 is positioned lying flat.

In an alternative embodiment, the telescopic rail device 22 can also be arranged in a raised position, so that in comparison to the illustration in 3 rails 24 and 25 would be positioned rotated 90°.

Provision can be made for an upper side 27 of the storage shelf 20 to have a specific covering which is designed to be antibacterial and/or non-slip and/or moisture-absorbing. However, provision can be made for a corresponding support to be applied to this top side 27 , which can then also be removed from the top side 27 .

The pull-out trolley 9 is designed with its design with the plate-like shelf 20, its door 6 and the rear wall 21 for the direct placement of food. In addition to or instead of this, it can also be provided that trough-like food storage containers are also set up on the storage shelf 20, as is shown in 4 shown by food receptacles 28, 29 and 30 in an exemplary embodiment. The number, size and position of the food receptacles 28, 29 and 30 is to be understood as an example only. In the exemplary embodiment, the food receptacles 28 to 30 are transparent shells made of plastic, in which a wide variety of foods can be stored. You can like this in 4 shown by way of example using the food storage container 28, can be handled by a user from above or from the side and placed on the shelf 20 or removed. As can be seen, the food storage container 29 and the two food storage containers 28 and 30 in total are dimensioned in their extensions in the depth direction and thus in the z-direction such that they are arranged relatively securely between the rear wall 21 and the door 6.
