This application claims the benefit, under 35 U.S.C. § 119, of German Patent Application DE 10 2016 224 383.7, filed Dec. 7, 2016; the prior application is herewith incorporated by reference in its entirety.
The invention relates to a method for adjusting the position of a door on a housing of a household refrigeration appliance in which the placement of the door while located on the housing is changed. When the door is in its closed state, a leaf of the door is located so as to be separated from a front flange of the housing by a gap, as viewed in a depth direction of the household refrigeration appliance. The invention further relates to a household refrigeration appliance.
In known household refrigeration appliances, it is important for the placement of the front doors to be precisely aligned with the housing, so that no tilting is visible from the front. Any such tilting relative to the housing is also noticeable in relation to further parts which are located directly adjacent the door at the front of the household refrigeration appliance. If such a household refrigeration appliance has a second door at the front, for example, an imprecise placement of the first door relative to the housing then means an imprecise placement relative to that further door. Any gaps that are present between such doors are then uneven over their entire length, which is likewise visible from the front, and results in a visual appearance which is qualitatively disadvantageous as well as possibly restricting or preventing an intended insertion of the fingers into such a gap in order to reach behind a door, for example. That can also cause deflection or rubbing of the door against other parts of the appliance during movement.
It is accordingly an object of the invention to provide a method for adjusting the position of a door of a household refrigeration appliance, and a household refrigeration appliance, which overcome the hereinafore-mentioned disadvantages of the heretofore-known methods and appliances of this general type and which permit the position of a door to be adjusted easily, quickly and precisely.
With the foregoing and other objects in view there is provided, in accordance with the invention, a method for adjusting the position of a door of a household refrigeration appliance, in which the door is pivotably located on a housing of the household refrigeration appliance. In this case, the placement of the door while located on the housing is changed. When the door is in its closed state, a leaf of the door is located so as to be separated by a gap from a front flange of the housing, as viewed in a depth direction of the household refrigeration appliance. It is considered an important concept of the invention that a tool is inserted into the gap and a readjustment element which is accessible through the gap on the household refrigeration appliance is readjusted by using the tool in such a way that the position of the door relative to the housing is changed in at least one spatial direction as a function of this readjustment of the readjustment element. By virtue of such an embodiment, it is possible to quickly and precisely readjust the placement and hence the position of the door relative to the housing. In particular, the tool can be applied directly to the readjustment element through the gap, without first having to remove extensive cover parts or the like in order to be able to reach the readjustment element. Moreover, by virtue of this embodiment, the readjustment element is nonetheless located so as to be protected and effectively accommodated in the gap.
In particular, the gap is widened in a depth direction of the household refrigeration appliance at an end region, in particular an upper and/or lower end region as viewed in a height direction of the household refrigeration appliance, thereby forming an access channel in the gap, through which the tool can be introduced and can reach the readjustment element and directly engage therewith in the access channel.
The gap is preferably open towards the side in a width direction of the household refrigeration appliance, and the tool is introduced into the gap in a width direction and engaged with the readjustment element. Since the side access is particularly simple and the operation of the tool is also ergonomically very user friendly, this is a particularly advantageous embodiment. Since the access point can easily be found from the side and the user has a degree of view into the gap, the engagement of the tool with the readjustment element can be effected easily and reliably when then tool is introduced into the gap.
Provision can also be made for the gap to be open towards the top and/or the bottom as seen in the height direction of the household refrigeration appliance, and for the tool to be introduced into the gap in this height direction and engaged with the readjustment element. This also has a corresponding advantages in specific embodiments.
The readjustment element is preferably oriented or aligned in a width direction of the household refrigeration appliance. The readjustment element is preferably readjusted in a width direction in order to change the position of the door relative to the housing. In particular, this allows the position of the door to be changed relative to the housing in this width direction. An identical orientation of both the introduction of the tool into the gap, and the orientation of the readjustment element and the movement of the readjustment element, is therefore associated with the direction in which it is then possible to modify the position of the door. This provides a particularly intuitive readjustment concept for a user, in such a way that even in the case of very small and precisely controlled positional changes, modifying the position and implementing the change can be effected quickly and understood easily.
Provision is preferably made for the door to be pivotably mounted on the housing by using a bearing device, wherein the bearing device has a bearing angle adjustment plate which is rotatably connected to the door and a separate bearing angle base plate which is statically located on the housing. The bearing angle adjustment plate is connected to the bearing angle base plate through the readjustment element, and the bearing angle base plate and the bearing angle adjustment plate are moved relative to each other by operating the readjustment element in order to effect a change in the position of the door relative to the housing accordingly. This multicomponent structure of the bearing device allows both an embodiment which requires minimal structural space and a very simple concept for readjusting the placement of the door on the housing. The two plates per se are relatively robust and mechanically highly resilient parts, which are located in such a way that they can be moved relative to each other. The two above-mentioned plates are moreover so oriented as to be parallel to each other and overlap sectionally. It is thereby possible to achieve both a particularly effective engagement and a particularly simple concept for the movement of the plates relative to each other, even in the engaged state.
The bearing angle adjustment plate is preferably moved in a width direction of the household refrigeration appliance relative to the bearing angle base plate, in order to change the position of the door relative to the housing. In this case, it is not intended for the bearing angle adjustment plate as a whole to be displaced relative to the door on which the bearing angle adjustment plate is located, and in this regard only a rotational movement of these two components relative to each other is possible.
In a further advantageous embodiment, the bearing angle base plate is so constructed as to include an engagement peg, which passes through an opening in the bearing angle adjustment plate. The readjustment element is connected to that section of the engagement peg which passes through the opening and to an engagement peg of the bearing angle adjustment plate which extends parallel to the engagement peg of the bearing angle base plate. By virtue of such an embodiment, the readjustment element is raised and positioned in an offset manner relative to the two plates, thereby allowing simple and clear access for the tool and moreover allowing very precise control of the device for readjustment. Specifically, a transfer of force initially takes place to the effect that these two engagement pegs are directly connected to the readjustment element, and by using a corresponding readjustment of the readjustment element a direct force effect on these two engagement pegs takes place. The location and embodiment of the engagement pegs also generates a correspondingly effective path of force, which is then transferred to the two plates, in such a way that they can also be moved relative to each other with very precise control and accurate placement. This in turn has a corresponding positive effect on the readjustment of the placement of the door relative to the housing.
A relative position that is adjusted between the bearing angle adjustment plate and the bearing angle base plate is preferably fixed. The resulting adjustment of the position of the door relative to the housing is thereby fixed correspondingly.
A locking screw is preferably tightened for the purpose of fixing the position. With respect to its screw direction, the locking screw is preferably oriented in a different spatial direction than the readjustment element, in particular perpendicular thereto. The locking screw is preferably oriented in a height direction, in such a way that the locking action or locking force acts in this height direction. The bearing angle adjustment plate and the bearing angle base plate are preferably oriented in a horizontal plane, which therefore extends over the width direction and the depth direction.
The adjustment of the door position is preferably performed when the door is in its fully closed state. This is a further very advantageous embodiment, since it means that the door does not have to be opened before it can be brought into a readjustment position relative to the housing, and therefore for the purpose of such adjustments to the placement of the door it is consequently not necessary to establish an adjustment position for the door before the tool can be used, and it is instead already possible to operate the tool immediately in this closed position of the door. Therefore the assembly is very quick and a corresponding readjustment of the door position is immediately apparent, since in particular the closed setting of the door helps to make an imprecise placement particularly noticeable. When the position of the door is readjusted by applying the tool to the readjustment element in this closed setting, the modified placement of the door relative to adjacent components is therefore also immediately apparent.
An adjustment screw is preferably used as a readjustment element, wherein the position of the door is adjusted by turning the adjustment screw.
In a further advantageous embodiment, provision is made for the bearing angle base plate to have at least one integrated guide peg which projects through a guide slot in the bearing angle adjustment plate in such a way that, in addition to the advantageous embodiment in which the engagement pegs of the two plates are so oriented as to correspond to each other, a separate mechanical engagement is thereby realized at a distance from the engagement pegs. The straight-line linear movement between the plates is thereby aided to a considerable extent in particular, and is again specifically guided by this additional guide peg. In particular, the straight-line readjustment of the door relative to the housing is thereby assisted in a particularly advantageous manner.
The embodiment including the readjustment element also allows a continuous and therefore stepless adjustment of the position of the door relative to the housing.
The orientation of the locking screw means that it is easily accessible from above and is not covered, so that in this case this locking screw can likewise be found quickly and operated immediately by using a corresponding tool.
With the objects of the invention in view, there is concomitantly provided a household refrigeration appliance, which is constructed in particular to perform a method according to invention or an advantageous embodiment thereof and which comprises a housing on which a door is pivotably located, the door allowing a storage space for food to be sealed at the front and the storage space being provided in the housing. The household refrigeration appliance has an adjustment device for adjusting a position of the door relative to the housing. It is considered an important concept of the household refrigeration appliance that a gap is formed between the door and a front flange of the housing, at least when the door is in its closed state, providing an access channel to the adjustment device. A tool can be introduced directly into this access channel, and a readjustment element of the adjustment device is located in such a way that it can be engaged by the tool that has been introduced into the access channel and then readjusted, whereby the position of the door can be adjusted accordingly. Advantageous embodiments of those material components of the household refrigeration appliance mentioned above with reference to the method, in particular the bearing device, are also considered to be advantageous embodiments of the household refrigeration appliance.
The bearing angle adjustment plate is located so as to overlap the bearing angle base plate at least sectionally, and is located above the bearing angle base plate in a vertical direction and positioned so as to be seated thereon.
Any references to “above,” “below,” “in front of,” “behind,” “horizontal,” “vertical,” “depth direction,” “width direction,” “height direction,” etc. refer to positions and orientations which assume a standard use and standard location of the appliance and an observer then standing in front of the appliance and looking in the direction of the appliance.
Further features of the invention are derived from the claims, the figures and the description of the figures. The features and combinations of features cited in the foregoing description, and the features and combinations of features cited in the following description of the figures and/or shown in the figures alone, are not used solely in the respective combination specified, but can also be used in other combinations without thereby departing from the scope of the invention. Consequently, the invention is considered to encompass embodiments which are not explicitly shown and explained in the figures, but which are suggested by the embodiments that are explained and can be derived therefrom by separate combinations of features. Therefore embodiments and combinations of features are also considered to be disclosed which do not have all the features specified in the original wording of an independent claim. Moreover and in particular by virtue of the embodiments explained above, embodiments and combinations of features are considered to be disclosed which extend beyond or deviate from the combinations of features stated in the back-references of the claims.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a method for adjusting the position of a door of a household refrigeration appliance, and a household refrigeration appliance, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
Referring now in detail to the figures of the drawings, in which identical or functionally identical elements are denoted by the same reference characters, and first, particularly, to
In the exemplary embodiment, the household refrigeration appliance 1 also has a further storage space 6, a freezer compartment in this case, which is separate from the first storage space 3. This further storage space 6 can be sealed at the front by a further separate door 7. This door 7 is preferably a front wall of a drawer which can be pushed in and pulled out in a depth direction (z-direction).
It can be seen that a gap 8 is formed between the two doors 4 and 5. A further gap 9 is also formed between the door 4 and the door 7. A gap 10 is likewise formed between the door 5 and the door 7. In order to ensure functionally reliable operation of the doors over the long-term, and their operability when grasped by a user in particular, it is particularly advantageous if these gaps 8, 9 and 10 are adjusted precisely. Moreover, the adjustment of a precise gap dimension is also particularly advantageous with regard to a soothing high-quality appearance.
The bearing angle adjustment plate 17 also has an engagement peg 19 which is formed integrally on or in one-piece with the bearing angle adjustment plate 17. The engagement peg 19 is a bent bracket and bends upwards at a projecting end of the bearing angle adjustment plate 17. The projecting end is opposite to the end at which the engagement pin 18 is formed. This engagement bracket or engagement peg 19 has an opening 20 which, in particular, can also include an internal thread. Furthermore, the bearing device 12 has a bearing angle base plate 21 which is separate from the bearing angle adjustment plate 17 and is located on the housing 2 in a positionally fixed manner. This bearing angle base plate 21 likewise is preferably L-shaped. The bearing angle base plate 21 has a guide peg 22 which forms an integral part of the bearing angle base plate 21 or is formed in one-piece therewith and projects upwards from the plane of the bearing angle base plate 21. The exemplary embodiment includes a second engagement peg 23 at a distance from the guide peg 22. The engagement peg 23 is likewise formed as an integral part of the bearing angle base plate 21 or is formed in one-piece with the bearing angle base plate 21 and extends upwards in a raised manner above the plane of the bearing angle base plate 21.
The embodiment shown in
An insertion region 25 of the readjustment element 24 is introduced into a support 26 in the engagement peg 23 of the bearing angle base plate 21. Furthermore, the adjustment device 16 also has a locking screw 27, through the use of which it is possible to fix an adjusted position between the bearing angle adjustment plate 17 and the bearing angle base plate 21, and a resulting adjusted position between the door 5 and the housing 2.
As is shown in
The guide peg 22 is introduced into a guide slot 31 in the bearing angle adjustment plate 17 and can be linearly moved therein in practice.
Starting from a normal position shown in
In particular, the embodiment explained in this case is also correspondingly provided at a bottom end of the door 5 in a height direction, in such a way that a corresponding bearing device 12 and a corresponding adjustment device 16 are provided there. A corresponding access channel 15 is also formed there.
