Description

The invention relates to a refrigeration device, in particular household refrigerating appliance, according to the preamble of claim 1.

To connect the appliance door of the refrigerator either on the right or on the left front of the appliance, the refrigerator can be equipped with door stops on both sides. Depending on the design, therefore, the door can be hinged to the left or right door stops.

From the DE 198 25 979 A is a generic refrigerator known, which has at its front lower corner portion a door bearing housing part in which a bearing plate can be fixed device. On the bearing plate, the door is hinged on the bottom side. The door bearing housing part defines a receiving space in which the bearing plate can be inserted and thus easily prepositioned. Subsequently, the thus pre-positioned bearing plate can be fixed with mounting screws.

In a door stop change that is from the DE 198 25 979 A1 known refrigeration device technically complicated to tilt on its back, whereby the mounted on the bottom side door bearing housing part is accessible. Subsequently, locking screws can be loosened or tightened to mount the bearing plate in the left-side or right-hand door bearing housing part.

The object of the invention is to provide a refrigeration device, in particular domestic refrigeration appliance, which is easy to install from a technical point of view.

A refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge freezer or a wine storage cabinet.

The object of the invention is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.

According to the invention, the refrigeration device has at least one door bearing housing part, in which a bearing plate can be fixed to the device, to which a door can be hinged at the front. The bearing plate is secured by means of at least one releasable securing element fixed in the door bearing housing part. According to the invention, the securing element has a tool attachment which is accessible on the device front side. For mounting or dismounting of the bearing plate, therefore, the refrigeration device is no longer to tilt on its back to make the fuse element accessible. Rather, according to the invention, the fuse element device front side accessible without the refrigeration device must be tilted for this purpose.

With the securing element unintentional withdrawal of the bearing plate can be prevented from the door bearing housing part. For further assembly-technical simplification, the securing element can be used in the Bautiefenrichtung in the door bearing housing part. The securing element may preferably be a screw, the screw head is accessible as a tool approach device front side.

The tightened in the housing part screw can press with its screw the bearing plate against a trained in the receiving space depth stop. For this purpose, the bearing plate may have a fixing stop on its outer circumference, with which the screw head of the screw element can be brought into abutment. The threaded shaft of the screw is thus guided past the side of the bearing plate used in the housing part, but not passed through a formed in the bearing plate screw hole. With the edge provided on the bearing plate Fixieranschlag can thus be dispensed with such a screw hole in the bearing plate.

The bearing plate may preferably be a plate-shaped sheet metal blank whose material thickness may be in the range of 5 mm. The door bearing housing part may also be designed as a sheet metal part, the sheet thickness may be in a range of 1.5 mm. This results in a total of low, required for the door bearing height.

As already mentioned above, the door bearing housing part may have a pocket-shaped receiving space in which the bearing plate can be inserted. The pocket-shaped receiving space can be open at the front. In order to ensure a simple and correct position mounting of the bearing plate, a stop contour can be provided within the housing part having side and / or depth stops. With the stop contour, the bearing plate can be pre-positioned in the device side direction and in the Bautiefenrichtung backward substantially free of play. The ceiling height of the receiving space can in this case be dimensioned so that the bearing plate can be used without play in the door bearing housing part in the device vertical direction. In this way, the bearing plate assembly technology is easily pre-positionable in the door bearing housing prepositioned. After Successful pre-positioning then the bearing plate can be secured by means of the releasable securing element against pulling out of the door bearing housing part. The screw head therefore serves as a further depth stop, which prevents the removal of the bearing plate from the door bearing housing part.

The appliance door can be articulated by means of an upper-side door bearing housing part and a bottom-side door bearing housing part on the device body of the refrigerator. In refrigerators with a larger height also a middle door bearing housing part can be provided on which either a vertically long door or two superimposed device doors can be hinged. In addition, for an optional left- or right-side linkage of the door on both the left side edge and on the right side edge each door storage housing parts be kept in the bearing plates for pivotal mounting of the door can be used if necessary. The right and left arranged door bearings are arranged in mirror image with respect to a aligned in depth direction, central axis device.

To reduce component complexity, it is advantageous if the insertable in the door bearing housing parts bearing plates are designed to be identical, regardless of whether the bearing plate in an upper, lower or middle door bearing housing part or left side or right side is used.

The bearing plate protrudes in the installed position with a boom from the door bearing housing part. Depending on the structural conditions, the bearing plate boom on the left and right sides of the device can each project laterally obliquely outwards.

In this case, the two geometric center axes of the bearing plates are inclined at an angle with respect to the above-mentioned central axis of the device, and the center axes intersect on the central axis of the device due to the mirror image arrangement of the left and right door bearings.

In such a geometric constellation, it is preferred if the insertable in the left-side or right-hand door bearing housing part bearing plate is designed with respect to their respective center axis mirror-symmetrical. In this case, namely, the bearing plate can be used alone by pivoting in the same mounting plane either in the left door bearing housing part or in the right door bearing housing part. In a door stop change, therefore, no additional rotation of the bearing plate about the central axis is required. The mirror-symmetrical about the center axis bearing plate may preferably have two mutually mirror-symmetrically arranged Einsteckschenkel, which are in each case in the left-side or in the right-hand door bearing housing part form-fitting manner brought into contact. The boom of the bearing plate can pass directly into the Einsteckschenkel, which are received in the door bearing housing part.

For a positionally correct pre-positioning of the bearing plate located within the door bearing housing part stop contour may have an undercut, which is engaged behind by one of the above-mentioned Einsteckschenkel the bearing plate. The undercut provided in the stop contour may be preceded by a projection with a stop edge. When inserting the bearing plate in the door bearing housing part therefore must first be overcome by an inclination of the bearing plate, the stop edge of the projection to then come into engagement with the underlying undercut. In the case of improper pre-positioning, the bearing plate, on the other hand, comes into direct contact with the stop flank. This results in a significantly different from the correct mounting position position of the bearing plate, so that a faulty installation is immediately noticeable.

In one embodiment, the stop contour may be made of the same material and / or integral with the door bearing housing part. The door bearing housing part can be made in this case, for example, an injection molded part made of metal or a plastic with a correspondingly large component strength. In contrast, it is preferred for reasons of cost, if the stop contour is formed in a separate from the door bearing housing part insert. In this case, the door bearing housing part may be geometrically simply formed as a sheet metal part, while in the separate insert a complex stop contour can be formed.

Hereinafter, an embodiment of the invention with reference to the accompanying figures will be described.

In the 1 is a refrigerator with a device body shown in which a lower refrigerator 1 and a separate upper cooling compartment 3 are arranged. The two cold rooms 1 . 3 are by means of only indicated device doors 5 . 7 can be closed on the front of the device. The two appliance doors 5 . 7 are about a vertically oriented axis of rotation A laterally on an upper door bearing 9 , a middle door storage 10 and a bottom door hinge 11 hinged.

Each of these door bearings 9 . 10 and 11 consists of a door bearing housing part 10 and a bearing plate inserted therein 14 , which are described in detail with reference to the following figures.

According to the 1 are the appliance doors 5 . 7 hinged on the left side of the device body of the refrigerator. Optionally also a right-side linkage of the device doors 5 . 7 to allow are mirror images of the right side of the 1 also shown door body parts 19 provided, in the optional the associated bearing plates 14 can be used. In the 1 is the upper right door bearing housing part 19 and the middle right door bearing housing part not shown in detail 19 without bearing plate 14 shown. In the right lower door bearing housing part, however, is a bearing plate 14 used in double function at the same time also for holding the right device foot 18 serves.

In the 2 is the lower right corner of the refrigerator in a bottom view with the lower door bearing 11 shown. At the bottom door storage 11 is appliance door 5 hinged, which closes the front lower feed opening of the refrigerator. The loading opening is in a conventional manner of a plastic frame 4 removed, which is part of a deep-drawn plastic inner container. The plastic frame 4 goes in device side direction x and in device vertical direction z outward in device front side end plates 6 above.

Like from the 2 further, it is the lower face plate 6 bottom side on a horizontally extending lower edge with a holding leg 8th angled. The front plate holding leg 8th engages under a floor part 2 , which reinforces the lower corner of the refrigerator. In that, in the 1 not shown lower left corner area is also an identical bottom part 2 intended for reinforcement. On the top of the bottom part 2 a z. B. made of cardboard boundary wall 13 , which defines a cavity at the bottom, which is filled with not shown Wärmeisolierschaum.

The above-mentioned lower door bearing 11 has a housing-mounted plate-shaped bearing plate 14 on one of the in the 2 shown upstanding bolts 15 a bearing bush shown only by dashed lines 17 wearing. In the assembled state, the appliance door is rotatable on this bearing bush 17 stored. In addition, the bearing plate carries 14 an already mentioned height-adjustable device foot 18 , which threaded into engagement with the bearing plate 14 located. The bearing plate 14 is made of a solid sheet metal part, whose in the 2 shown sheet thickness s _{1 is} in the range of 5 mm.

The bearing plate 14 is according to the figures in the door bearing housing part 19 fixed device. The housing part 19 is also a sheet metal part whose plate thickness is in the range of 1.5 mm. Like in the 2 is shown limits the housing part 19 with his bottom 20 and its raised sidewalls 21 one in which 4 shown device front side open recording room 22 in which the bearing plate 14 is pluggable. The installation space h of the receiving space 22 corresponds essentially to the material thickness s _{1 of} the bearing plate 14 , In addition, in the recording room 22 of the housing part 19 provided in Bautiefenrichtung y and in the lateral direction x movement stops, which provides a backlash-free pre-positioning of the bearing plate 14 in the housing part 19 enable. The movement stop 23 is according to the 3 one from the ground 20 of the housing part 19 bent out sheet metal tab, while further stops in a plastic insert 35 are integrated, the stop contour 24 the contour of the inserted bearing plate 14 is adjusted.

After pre-positioning, the bearing plate can 14 by tightening a screw 25 against pulling out of the housing part 19 be secured. The screw used as securing element 25 can according to the 4 in one of the housing part floor 20 bent out sheet metal tab 26 be screwed. At the Tightening the screw 25 comes their screw head in press with a contact surface or an outer Fixieranschlag 27 the bearing plate 14 , causing the bearing plate 14 against the stop contour 24 the plastic insert 35 the face plate is pressed 6 forms together with the door bearing housing part 19 as well as the bottom part 11 a sheet metal part assembly which is loaded with large weight forces or counteracted Bodenauflagekräfte. So that the sheet metal part assembly receives the necessary component strength, form the sheet metal parts 2 . 8th . 14 . 19 a four-layer component composite, in which the sheet metal parts are assembled flat and without play. In addition, the components 2 . 8th . 14 . 19 connected by not shown in detail connection technology, such as by welding or clinching.

The bearing plates used in the refrigerator 14 are all designed as identical parts with identical geometry. Each of the bearing plates 14 according to the 6 a boom 29 on, in the installation position of the door bearing housing part 19 protrudes device front side. In addition, the bearing plate 14 a plug contour with Einsteckschenkeln 31 on, in the installation position positively in the door bearing housing part 19 are used. According to the 6 is the bearing plate 14 with respect to a central axis M designed mirror-symmetrical, with the two Einsteckschenkel 31 are also arranged mirror-symmetrically to each other. Immediately on the central axis M are each threaded openings 33 . 34 arranged in which the bolts 15 for the bearing bush 17 or the device foot 18 can be screwed. In the transition area between the boom 29 and the two insertion legs 31 are each laterally triangular recesses 37 in the bearing plate 14 incorporated. The acute-angled transition edges between the recesses 37 and the Einsteckschenkel 31 form fixing edges, in the installation position of the screw head of the screw 25 are overrun.

As mentioned above, the bearing plate 14 with its plug contour 31 in installation position, form-fitting in contact with a corresponding contact contour 24 , whereby a correct position positioning can be done. In the exploded view according to the 5 is the stop contour 24 in the plastic insert 35 integrated. The plastic insert 35 is essentially plate-shaped executed with a truss-like stiffening structure. When assembling the in the 4 shown, bottom door hinge 11 First, the plastic insert 35 in the door bearing housing part 19 inserted. Subsequently, the door bearing housing part 19 attached to the bottom of the refrigerator.

In the 6 is roughly schematically the installation position of the bearing plates 14 in the two bottom door hinge housing parts 19 shown. For reasons of clarity, however, only the relevant plant contour is here 24 the two door bearing housing parts 19 shown. The outer contour of the refrigerator is indicated only by dash-dotted lines. According to the 6 are the two, in the installed position bearing plates 14 aligned with each other so that their central axes M intersect on a central, in the depth direction y extending device axis G. With respect to this device axis G, the two center axes M are each inclined at an angle φ in the device side direction x to the outside. Due to the mirror-image with respect to the center axis M geometry, the bearing plates 14 in the manufacturing process only by a pivoting movement S by an angle of 2 × φ in the left-side or in the right-hand door bearing housing part 19 be used. An additional rotation about the central axis M is not required. As part of a large-scale production can therefore identical trained bearing plates 14 held and depending on the requirements simply by taking place in a mounting plane pivotal movement S in the left or right door bearing housing parts 19 be used.

In the, in the 6 shown mounting position is beyond the stop contour 24 the door bearing housing parts 19 one undercut each 36 provided, which is engaged behind by each of which is not in contact with the screw head fixing edge. When inserting the bearing plates 14 in the respective door bearing housing part 19 is therefore by tilting the bearing plate 14 the, the undercut 36 overcome overhang to the bearing plate 14 to install correctly.

In the other 7 and 8th are each detail views of the upper door storage 9 and the middle door storage 10 shown. The upper and middle door bearings 9 . 10 are basically identical to the lower door bearings shown in the previous figures 11 , Corresponding are the door bearings 9 . 10 with a door bearing housing part 19 and a usable therein bearing plate 14 executed. The used bearing plates 14 are identical to the bottom plates used bearing plates 11 , Unlike the lower bearing plate is in the middle bearing plate 10 both on the top and bottom in the screw thread 34 a bolt 15 used, which is respectively connected to the upper and the lower door. The opposite right-hand door bearings 9 . 10 are in accordance with the 1 functionless, leaving only the door bearing housing part 19 to be provided.

In the 9 is in a perspective sectional view of the door bearing housing part 19 shown according to a second embodiment. The bearing plate 14 is identically designed in the first embodiment and also in the same manner in the door bearing housing part 19 used. In difference to the first embodiment is in the 9 the stop contour 24 not in a separate plastic insert 35 executed, but integrally formed integrally and integrally on the inside of the door bearing housing part. The door bearing housing part can not be executed in this case from a formed by a bending process sheet metal blank, but approximately in an injection molding process, for example, from a suitable plastic material.
