Description

The invention relates to a household refrigerator comprising a housing containing a receiving space for food. The household refrigerator also comprises a first door and a separate second door. The two doors are arranged pivotably on the housing. The two doors close a receiving opening of the receiving space. The household refrigerator also comprises a door stop bar which is arranged outside the doors and thus outside the two doors. The door stop bar extends vertically in the receiving opening and is connected, on an upper end, to an upper partition wall defining the receiving opening. On a lower end, the door stop bar is connected to a lower partition wall defining the receiving opening. The two doors are arranged so as to rest on the door stop bar in the closed state.

A corresponding household refrigerator is disclosed in WO 2008/066542 A1. Here this vertical door stop bar, which is located outside the doors, is screwed both at its upper end and at its lower end to the partition walls, in each case by a plurality of separate screws. The screws in this case are screwed into the upper and the lower partition wall in the vertical direction and thus with their screw shanks parallel to the extent of the door stop bar. Such an embodiment is very complex in terms of mounting technology. Moreover, the completely vertical alignment of the door stop bar is only able to be achieved with difficulty. This has the result that, in the case of a door stop bar tilted to the front at the upper end or at the lower end in the depth direction of the household refrigerator and/or a door stop bar rotated outwardly about its longitudinal axis and/or in the case of a door stop bar inclined obliquely to the side in a vertical position at the upper end or at the lower end in the width direction of the household refrigerator, the closing behavior of the doors is restricted. In particular, one or both doors may be prevented from being completely closed and thus bearing in a sealed manner against the door stop bar. As a result, heat may be undesirably input into the receiving space via this interface. This also leads to an operation which is disadvantageous relative to energy consumption.

It is the object of the present invention to provide a household refrigerator in which such a vertical door stop bar which is located outside the doors is attached in a manner which is more positionally accurate and easier to mount.

This object is achieved by a household refrigerator which has the features as claimed in claim 1.

A household refrigerator according to the invention comprises a housing containing a receiving space for food. The household refrigerator also comprises a first door and a separate second door. The two doors are arranged pivotably on the housing. The doors close a receiving opening of the receiving space on the front face in the closed state. The household refrigerator also comprises a door stop bar which is arranged outside the doors. The door stop bar is arranged vertically in the receiving opening and is connected, on an upper end, to an upper partition wall and/or to a corresponding defining edge defining the receiving opening. Moreover, the door stop bar is connected, on a lower end, to a lower partition wall and/or a defining edge defining the receiving opening. The doors rest on the door stop bar in the closed state of the doors, on the front face and thus on the side of the door stop bar remote from the receiving space.

An essential idea of the invention is that the upper end of the door stop bar is connected to the upper partition wall by means of a first connector comprising an undercut. Alternatively or additionally, according to the invention it may also be provided that the lower end of the door stop bar is connected to the lower partition wall by means of a second connector comprising an undercut. Very simple and rapid mounting may be carried out by at least one such specific connection between one end of the door stop bar and a partition wall of the receiving opening. Moreover, by means of this embodiment in which a connector also comprises an undercut, it is possible to position the door stop bar in a manner which is very positionally accurate. Undesirable deviations from the vertical orientation of the door stop bar are thereby avoided.

It is preferably provided that the door stop bar comprises a first bar part, on the upper end an upwardly projecting protuberance being configured thereon, said protuberance being engaged, preferably being inserted, in an undercut in the upper partition wall. In this embodiment, therefore, the mechanical connection between the door stop bar and the upper partition wall is implemented by interlocking components, said connection also being correspondingly mechanically load-bearing. The protuberance extends, therefore, in the direction of the longitudinal axis of the door stop bar and thus extends the hollow part upwardly. The simple insertion of the protuberance into the undercut is also provided by this orientation and the engagement, so that the mounting may also be carried out very easily and rapidly.

It may also be provided that a downwardly projecting protuberance is configured on the lower end of the first bar part, said protuberance being engaged, preferably being inserted, in an undercut in the lower partition wall. The aforementioned advantages may also be achieved thereby.

Specifically due to this at least one connector the requirement for additional separate fastening elements, in particular screws, as is required in the prior art, may also be avoided. Moreover, the at least one connector may be a connection which is releasable in a non-destructive manner.

It is preferably provided that the door stop bar comprises a first bar part, on the upper end an undercut being configured thereon, a protuberance downwardly projecting from the upper partition wall being inserted therein, or an undercut being configured on the lower end of the first bar part, a protuberance upwardly projecting from the lower partition wall being inserted therein. This embodiment thus represents an alternative to the advantageous embodiment already described above. The advantages may be accordingly achieved herein.

In one advantageous embodiment, it is provided that an undercut is configured as a blind hole. As a result, it is possible for a protuberance to penetrate therein in a very simple manner and this undercut is therefore also configured with just one opening, the protuberance extending via said opening into the undercut. The penetration of dust or other contaminants through the undercut is prevented thereby. Moreover, by means of this embodiment the undercut is also configured per se to be very mechanically stable and is also able to absorb corresponding mechanical forces of the connector and/or when the protuberance is engaged, in particular when for example a door is shut with increased thrust and the door then strikes the door stop bar on the front face.

It is preferably provided that the upper partition wall comprises a receiver which is separate and spaced apart from the connector, the door stop bar being inserted therein. The receiver comprises a lateral receiving wall, the door stop bar bearing thereagainst in the mounted end position and a position of the door stop bar being fixed thereby in the width direction of the household refrigerator. Additionally or alternatively, the receiver preferably comprises a rear receiving wall, the door stop bar bearing thereagainst in the mounted end position and a position of the door stop bar being fixed and/or defined thereby toward the rear in the depth direction of the household refrigerator. By these additional advantageous embodiments the positional accuracy of the door stop bar is further improved. In particular, the completely vertical alignment of the door stop bar is promoted thereby and may also be permanently maintained.

It is preferably provided that the lower partition wall comprises a receiver which is separate and spaced apart from the connector, the door stop bar being inserted therein, wherein the receiver comprises a lateral receiving wall, the door stop bar bearing thereagainst in the mounted end position and a position of the door stop bar being fixed thereby in the width direction of the household refrigerator. Also in this case, additionally or alternatively the receiver may comprise a rear receiving wall, the door stop bar bearing thereagainst in the mounted end position and a position of the door stop bar being fixed thereby in the depth direction of the household refrigerator. Therefore, the advantages already set forth above relative to the alternative embodiment also apply in this embodiment.

In a preferred embodiment, the receiver is configured to be open toward the front and thus on the front face. The insertion and the accessibility relative to the door stop bar are thereby improved.

In one advantageous embodiment, it is provided that the door stop bar is of multipart configuration and thus is made up of a plurality of separate bar parts. As a result, it is possible to improve the mounting of individual parts. In particular, however, the door stop bar may also be designed to be multifunctional, since then it may be assembled for receiving and for individually attaching further components as required.

It is preferably provided that the door stop bar comprises a first bar part which is a backing piece terminating the door stop bar toward the receiving space and ii thus, with regard to the arrangement on the household refrigerator viewed in the depth direction, is the component of the door stop bar located furthest to the rear. This first bar part is configured in a trough-like manner. The trough region of this first bar part is arranged with its trough opening remote from the receiving space and thus in the closed state of the doors is positioned facing the doors. This is an advantageous embodiment since this first bar part is configured, in particular, integrally and thus no components or other material or dirt and/or dust are able to pass through this first bar part toward the rear into the receiving space. It is also possible, however, that by this specific geometric design of this first bar part, it is possible to receive desired material or other components in the trough region.

It is advantageously provided that this trough region of the first bar part is at least partially filled with a thermally insulating material, in particular an insulating foam. As a result, the thermally insulating effect of this vertically orientated door stop bar is also improved. Thus the door stop bar no longer acts as an undesired thermal bridge via which heat is input into the receiving space and/or via which cold escapes from the receiving space into the surroundings. Moreover, by means of this embodiment the door stop bar is also stabilized in its structure so that the first bar part is very torsionally stiff and dimensionally stable.

In one advantageous embodiment, it is provided that the door stop bar comprises a second bar part which is separate from the first bar part and which is arranged on the first bar part and covers the trough region of the first bar part on the front face. This second bar part may, therefore, serve as a cover for this trough region so that a material located therein, in particular a thermally insulating material, is not able to escape from the trough region of the first bar part, in particular is not able to escape toward the front.

It is preferably provided that the second bar part comprises a trough region, a heating unit being arranged therein for heating at least the door stop bar. As a result, a functional component, namely the heating unit, may be positioned at a locally specific point in a very space-saving manner. The door stop bar, therefore, is also a carrier for this additional functional component. By means of this heating unit, therefore, it is possible to heat the door stop bar, if required, in particular in a manner which is centered very locally. As a result, undesirable condensate or humidity may be dried or, in particular, even frost which has been produced may be thawed so that a seal of a door, which in the closed state of the door bears against the door stop bar on the front face, is not damaged.

It is preferably provided that the trough region of the second bar part is covered by a separate cover on the front face, in particular a metal plate. Moreover, this further functional component, namely the heating unit, is thus arranged to be protected thereby and thus protected from damage or any other negative influences. Furthermore, a stable component is provided by means of the cover, the striking forces of the doors when closed also being able to be absorbed thereby, so that the other bar parts are also protected thereby.

In particular, it is provided that a blind hole, in particular just one blind hole, is configured on the upper partition wall. A hole axis of this blind hole is oriented, in particular, in the depth direction of the household refrigerator. A backing piece is arranged in this blind hole on the upper partition wall, a screw being able to be screwed therein for fastening the door stop bar to the upper partition wall.

In an alternative or advantageous manner, only one such single blind hole, in particular oriented with a hole axis in the depth direction of the household refrigerator, is configured on the lower partition wall, wherein a backing piece is arranged in this blind hole as a separate component, a screw being able to be screwed therein for fastening the door stop bar to the lower partition wall.

By means of this design, in one advantageous embodiment it is achieved that a screw connection is required either only at the upper end or at the lower end of the door stop bar and in this regard this screw connection is achieved by just one screw. This screw is thus oriented with its screw shank in a specific direction, namely in the depth direction of the household refrigerator. Easy accessibility and a simple screw connection are ensured thereby.

In one advantageous embodiment, it is provided that just one vertically upwardly projecting protuberance is configured on an upper end of the door stop bar, in particular of the first bar part, said protuberance penetrating an undercut in the upper partition wall and a connector being produced thereby. A screw passage for a screw is configured on the lower end of the door stop bar, and this single blind hole is configured merely on this lower partition wall for introducing a backing piece.

In an advantageous embodiment relative thereto, therefore, the connection is configured at the lower end only by means of a single screw at a specific point and with a specific orientation and the upper end of the door stop bar is fastened to the upper partition wall only by a further simple geometrically unique connector without screws. This is a minimal fastening concept of the door stop bar which, in particular in combination with an additional separate receiver as has been advantageously described above, provides very simple and rapid mounting and a positionally accurate vertical arrangement of the door stop bar.

The terms “upper” “lower” “front” “rear” “horizontal” “vertical” “depth direction” “width direction” “vertical direction”, etc. indicate the positions and orientations provided when the device is used as intended and when the device is arranged as intended and with an observer standing in front of the appliance and looking in the direction of the appliance.

Further features of the invention are disclosed from the claims, the figures and the description of the figures. The features and combinations of features cited above in the description and the features and combinations of features cited hereinafter in the description of the figures and/or shown individually in the figures are not only able to be used in the respectively provided combination but also in other combinations without departing from the scope of the invention. Thus embodiments of the invention, which are not explicitly shown and described in the figures but are revealed and are able to be produced by separate combinations of features from the described embodiments, are also to be regarded as encompassed and disclosed. Embodiments and combinations of features, which therefore do not have all of the features of an originally formulated independent claim, may also be regarded as disclosed. Moreover, embodiments and combinations of features which go beyond or deviate from the combinations of features set forth in the back-references of the claims may be regarded as disclosed, in particular by the embodiments set forth above.

Exemplary embodiments of the invention are described in more detail hereinafter with reference to schematic drawings, in which:

FIG. 1 shows a perspective view of an exemplary embodiment of a household refrigerator according to the invention;

FIG. 2 shows a perspective view of an internal container of the household refrigerator according to FIG. 1 with a vertical door stop bar outside the doors;

FIG. 3 shows a perspective sectional view of the embodiment and FIG. 2;

FIG. 4 shows an enlarged view of a first partial detail of FIG. 3; and

FIG. 5 shows an enlarged perspective view of a second partial detail of FIG. 3.

Elements which are the same or functionally the same are provided in the figures with the same reference characters.

In FIG. 1 a household refrigerator 1 which has a housing 2 is shown in a perspective view. A first receiving space 3 is configured in the housing 2, said receiving space being configured for receiving food. The receiving space 3 is a contiguous receiving space which, therefore, has a corresponding volume. The first receiving space 3 is defined by walls of an internal container. A receiving opening 4 is configured on the front face, said receiving opening being in the x-y plane and thus in a plane which is spanned by the width direction and the vertical direction of the household refrigerator 1, and being a contiguous receiving opening 4 and/or a loading opening which is uninterrupted in terms of surface area. The receiving opening 4 on the front face is defined by a first defining edge and/or a lower first partition wall 5, an opposing upper second partition wall 6 and/or a defining edge and in each case adjoining and opposing vertical defining edges and/or partition walls 7 and 8. The receiving opening 4 is, therefore, defined on the peripheral side and by a defining edge and in terms of surface area is a square and/or a rectangle.

The receiving space 3 is preferably a refrigerating chamber in which food may be stored, in particular at temperatures greater than freezing point, in particular between +4° C. and +10° C.

The exemplary household refrigerator 1 according to FIG. 1 also comprises a second receiving space 9 which is configured separately from the receiving space 3 and is configured in the vertical direction and thus in the vertical direction of the household refrigerator 1 below the first receiving space 3.

The further receiving space 9 is able to be closed by a single door 10 which in FIG. 1 is shown in the fully closed state. The door 10 is arranged on the housing 2 and is rotatable about a rotational axis extending in the vertical direction.

Preferably, however, the door 10 is part of a drawer which may be displaced in a linear manner in the depth direction.

The household refrigerator 1 also comprises a first door 11 and a separate second door 12 which is also arranged pivotably on the housing 2. The two doors 11 and 12 are arranged for closing the receiving space. The doors are shown in the open state in FIG. 1. By way of example, door shelves are configured on the inner faces 13 and 14 of the doors 11 and 12, only one thereof being provided with the reference character 15.

Moreover, a batten-shaped and thus also linear door bar 16 is arranged outside the doors 11 and 12. The door bar 16 is fixedly arranged on the housing 2. To this end, the door bar 16 is connected on a lower first end 17 to the first partition wall 5 and on an upper second end 18 to the upper partition wall 6. The door bar 16 is an integral component and extends in the vertical direction and thus vertically above an extent which corresponds to the clear width between the partition walls 5 and 6. The door bar divides the receiving opening 4 into two surface areas, in particular of the same size.

An internal container 19 which with its walls defines the receiving space 3 and which on the front face has a loading opening, which is formed by the receiving opening 4, is also shown.

In FIG. 1 it may also be identified in the view that the vertical door stop bar 16 divides the receiving opening 4 in the width direction and thus in the x-direction, which means that the door stop bar 16 is arranged, in particular, centrally in the width direction.

In particular, it is provided that the lower partition wall 5 and the upper partition wall 6 are integrated in the internal container 19 and thus define portions of a top wall and/or a bottom wall on the front face which define the receiving space 3. The internal container 19 also has further vertical side walls, not identified further for the purposes of clarity, and a rear wall which also define the receiving space 3.

In FIG. 2 the internal container 19 is shown in a perspective view and the vertical door stop bar 16 outside the doors is shown in the fastened state.

In FIG. 3, the component arrangement according to FIG. 2 is shown in a perspective sectional view along the cutting line III-III. As may be identified in the enlarged view of the region I of FIG. 3 in FIG. 4, the door stop bar 16 is designed as a multipart component and is made up of a plurality of separate bar parts.

As may be identified in the view in FIG. 4, the door stop bar 16 is configured with a first bar part 20 which is designed integrally from plastic. This first bar part 20 has a trough region 21 which is remote from the receiving space 3 and thus is open toward the front and/or on the front face and thus has a trough opening 22. In the mounted end state, a thermally insulating material, in particular an insulating foam 23, is contained in this trough region 21.

This first bar part 20 on an upper top wall 24 has a raised upwardly projecting protuberance 25 which is thus oriented vertically upwardly. This protuberance 25 engages in an undercut 26 which is configured as a blind hole and is configured integrally in the upper partition wall 6. As a result, a connector 27 is configured between the door stop bar 16, in particular the first bar part 20 and the upper partition wall 6.

Moreover, the upper partition wall 6 has a receiver 28 which is separate and spaced apart from this connector 27. The door stop bar 16 is also inserted and arranged in this receiver 28 so as to be embedded therein with its upper end 18.

The receiver 28 is defined to the rear by a rear receiving wall 29. The receiver is defined upwardly by an upper receiving wall 30. In the width direction and thus in the x-direction the receiver is defined by a lateral receiving wall 31.

By this receiver 28 a positional adjustment is also provided so that the door stop bar 16 is retained in the width direction and thus in the x-direction in a positionally accurate manner and in the depth direction is correspondingly retained to the rear and does not penetrate too far. As a result, the vertical positional accuracy is improved, in particular also in the case of an operative connection with the connector 27.

As may also be identified in FIG. 4, the door stop bar 16 comprises a separate second bar part 32. This second bar part 32 is connected to the first bar part 20 and is arranged on the first bar part 20 on the front face. The second bar part 32 preferably extends over the entire height of the first bar part 20. The second bar part 32 also comprises a trough region 33 which entirely covers the trough region 21 of the first bar part 20 on the front face.

A further functional component of the household refrigerator 1 is arranged in the trough region 33 of the second bar part 32. In particular, it is provided that a heating unit 34 is arranged in this trough region 33.

Moreover, the door stop bar 16 comprises a cover plate 42 shown in FIG. 4 and FIG. 5 (which is transparent for illustrative purposes) which represents a third separate component of the door stop bar 16. By means of this cover plate 42, which in particular is a metal plate, the trough region 33 is covered on the front face. The cover plate 42 is preferably flush on the front face with the laterally adjacent walls of the second bar part 32 as shown in FIG. 4.

It is provided that only this one protuberance 25 and only this one undercut 26 are formed according to the view in FIG. 4.

Moreover, in FIG. 4 a stop on the front face is configured integrally in the top wall 24. This stop is S-shaped and, in particular, configured as a flange 43. This stop may be used to mount the door stop bar 16: thus, relative to a plane which encompasses the receiving opening 4 of the internal container 19, the door stop bar 16 may be positioned obliquely with the stop against the rear receiving wall 29 and then pivoted into the plane. During this pivoting procedure, the protuberance 25 engages in the undercut 26. After the pivoting procedure, the door stop bar 16 may be screwed on at its lower end portion.

In the view according to FIG. 5 the enlarged view of the detail II in FIG. 3 is shown. Here it may also be identified that a receiver 35 which is open to the front is configured in the lower partition wall 5, said receiver comprising a lower receiving wall 36, a rear receiving wall 37 and a lateral receiving wall 38. Relative to the lateral receiving wall 38, as is the case of the receiver 28 which is open toward the front in the upper region, a further corresponding lateral receiving wall is also arranged on the opposing side in the width direction so that a positional accuracy and retention in the width direction is provided on both sides in the x-direction.

Also according to the view in FIG. 5, the door stop bar 16 in the lower region is arranged so as to be recessed and/or embedded in this further receiver 35. In particular, the second bar part 32 is arranged so as not to protrude toward the front beyond this receiver 28 and the receiver 35.

As may also be identified, this receiver 35 has an integrally formed blind hole 39. In particular, a backing piece 40 is able to be inserted therein. Both the first bar part 20 and the second bar part 33 in each case have a through-hole 41, a screw being able to be inserted through said through-hole and screwed to the backing piece. The hole axis in this case is oriented in the depth direction and thus in the z-direction, so that the screw is oriented in this depth direction when it is fastened. It is also provided that just one screw is present here. The entire door stop bar 16 is thus fastened and aligned by the one connector 27 in the upper region and the one screw connection in the lower region and, in particular, additionally positioned and secured in terms of position by the receivers 28 and 35.

It may also be provided that the connector 27 is configured in the lower region and the screw connection is configured in the upper region. This would then be a reverse embodiment relative to the description of FIG. 4 and FIG. 5.
