Description

The present invention relates to a refrigerator and / or freezer with a body and a door for closing an opening of the device body, wherein a pivot bearing is provided, which the door relative to the device body a pivot axis is pivotally mounted.

Refrigerators and freezers usually have an elastic seal on their door with an integrated magnet that holds the sealing bead on the door onto the sealing contact surface pull on the device body. Because of the geometric conditions such swing doors is, however, in particular in the Area of the door, the desired, optimal sealing layer Not reached despite the inclined magnet in the sealing profile. The magnet pulls the seal prematurely onto the device body, so that the seal does not lie optimally and can walk when the door is pivoted further. Both lead to an unsatisfactory seal, which in freezers to one Increased freezing of the freezer compartment leads to premature wear the seal leads.

Figure 11 shows a known refrigerator in the area of the sealing pad between hinged door and device body, the door being closed is shown with an optimally fitting seal. The device body 1 has one essentially flat seal bearing surface 2, on which the seal 3, which on the Door 6 is attached, rests. As FIG. 11 shows, the seal 3 is more elastic Sealing bead formed in which a magnet 4 is integrated. This pulls the Seal 3 against the metallic seal support surface 2 of the device body 1. The optimal seal support of the seal 3 shown in FIG. 11 becomes however not always achieved:

Is the door 6 about the substantially vertical pivot axis 5 from the swung open Position swiveled, the magnet 4 first comes into contact with the system the seal support surface 2 of the device body 1, as shown in Figure 12. this applies even if the magnet 4 should be tilted. If the door 6 from the in Figure 12 pivoted further position, it can happen that the Door magnet 4 during the closing process due to the attractive force on the device body 1 is present and not in during the further closing process through the seal 3 the optimal position can be pushed. This sealing pad is different large, depending on the tolerances that occur. The magnet 4 sucks, so to speak prematurely fixed, which leads to flexing of the seal 3. Figure 13 shows one of these improperly deformed seal 3, which only leads to an unsatisfactory Sealing leads. In addition, the aforementioned flexing leads to the seal 3 their premature wear.

The present invention is therefore based on the object of an improved To create a refrigerator or freezer of the type mentioned, in which the Disadvantages of the prior art are avoided and the latter in an advantageous manner Way is trained. In particular, an improved opening and closing should the door with the best possible seal.

This object is achieved according to the invention by a refrigerator and / or freezer according to claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

According to the invention, an additional axis of movement is vertical for the door provided for their pivot axis. It can be the door relative to the pivot axis and / or the pivot axis relative to the device body in the direction perpendicular to Pivot axis be movably mounted. The pivot bearing is thus designed that in addition to the rotary pivoting movement of the door around the The door is roughly vertical in the area of the pivot axis to the sealing support of the device body away from it and moved towards it can be. This possibility of translational movement across Swiveling axis prevents the seal from flexing. The latter can essentially placed vertically on the opposite seal contact surface so that it always lies in the intended position and seals optimally. Likewise, when the door is opened, the seal is prevented from flexing because of the additional Axis of movement of the door perpendicular to the seal contact surface Seal is peelable vertically from the opposite seal support.

In a development of the invention, the movement of the door is perpendicular to the pivot axis controlled depending on the pivoting position of the door. A corresponding Movement control device can in particular be designed such that the Door at the beginning of a pivoting initially essentially perpendicular to Swivel axis and thus vertically moved away from the body of the device and vice versa the door is substantially vertical towards the end of each swivel to the swivel axis and thus perpendicular to the device body or its sealing surface is moving towards it. That overlaid the swivel movement Translational movement is therefore in the fully closed position the pivoting area adjacent to the door is provided, so that in this area the Door is moved translationally substantially perpendicular to the body of the device. in the The open, swiveling range of the door can then again be the conventional, pure one Pivotal movement may be provided.

Preferably, in particular for controlling the door movement transversely to the pivot axis in the area of the swivel axis between the device body and the door a cam device is provided which, depending on the pivoting position of the Door whose distance from the device body specifies. It can be a cam with one first curve section, which in the fully closed pivot position of the Door allows a position of the door close to the unit body, and with a second, be provided on the first adjacent curve section, one of the device body moved, distant position of the door. When opening the door the cam pushes the door off the seal support in the area of the swivel axis of the device body away. When closing, the door snaps or falls towards the end of the Swinging in vertically onto the seal support. The cam can basically be provided on the door or on the device body and on an opposite one Support the sliding surface. According to a preferred embodiment of the invention the cam is rigidly connected to the door so that it swings open and closed the door with its cam control surface arranged on a stationary side of the unit body Repositioning surface slides or rolls.

A prestressing device, in particular a spring device, is preferred for biasing the door relative to the pivot axis or the pivot axis relative to the device body in the direction of the additional axis of movement. The Spring device presses the pivot axis relative to the door or relative to the device body in their starting position, from which they then through the aforementioned cam when the door is pivoted appropriately against the spring preload is pushed out. The bias is directed such that when closed Door this is stretched towards the body of the device. It is expedient dimension the pretensioning device such that its pretensioning force is greater than sealing forces acting between the door and the body of the device, d. H. that not sealing forces already acting between the door and the body of the device make adjustments the pivot axis or pushing open the door.

The cam device and the pretensioning device advantageously act in this way together that in the end area of the pivoting movement of the door an automatic Closing the door is reached. The cam device and the biasing device together, so to speak, form an automatic locking device. The the door swings the last bit as a result of the pretensioning force and its implementation by the cam device by itself.

The additional axis of movement of the door perpendicular to the seal contact surface the device body is preferably achieved in that the door relative to the Device body is fixedly mounted pivot axis is movably mounted, and in the direction transverse to the longitudinal direction of the pivot axis. Basically it is in Kinematic reversal also possible, the door cannot be moved in the usual way and only be rotatably movable on the pivot axis and then the latter Movable in the direction perpendicular to the seal support of the device body to the device body to arrange. However, the aforementioned embodiment is preferred with swivel axis rigidly attached to the body of the device. In particular, can be provided here be that slots on the door side as bearing recesses for the swivel axis are provided in which the pivot axis is guided or with which the Door sits on the swivel axis. The slot-like bearing recesses extend perpendicular to the front and back of the door, making the one you want Movement perpendicular to the seal support of the device body is achievable.

Door holders can be provided, which are essentially free of play and Rotatable on the swivel axis and with a spring relative to the door in the direction are biased towards the door side facing away from the device body. By means of the said door holder, the pivot axis is preferably against one of the ends the slot-like bearing recesses of the door pressed so that a defined Position of the door is predetermined relative to the pivot axis when the cam device the axis does not push into another position.

The door holder and the cam device preferably form an assembly unit. According to an advantageous embodiment of the invention, it can be provided that a cam with a cam surface facing the device body is rigidly attached to the door and has a guide for each door holder, in which the respective door holder sitting on the swivel axis is perpendicular to the front and Back of the door is slidably guided.

Figure 1 shows a standing refrigerator and freezer that has a cubic body 1, the front of which has a refrigerator compartment opening and a freezer compartment opening has. The small freezer compartment opening on top is with the freezer compartment door 7 and the large refrigerator compartment opening below is with the refrigerator compartment door 6 locked. Both doors 6 and 7 are each about a vertical pivot axis pivotable, according to Figure 1 on the right side of the refrigerator and freezer lies.

Both doors each have an upper bearing and a lower bearing, the together define the pivot axis 5. The upper and lower bearings each door 6 and 7 can be designed accordingly, so that subsequent only the upper bearing of the refrigerator door 6 is described.

Figures 2 and 3 show in perspective the upper bearing of the refrigerator door 6. From Device housing or the body 1 jumps a bracket 8 in the form of a hinge plate 9 before that overlaps the door 6 on its upper side. On the hinge plate 9, a downwardly projecting hinge pin 10 is rigidly attached with the corresponding hinge pin of the lower bearing of door 6 Swivel axis 5 defined. The hinge pin 10 can be on the hinge plate 9 screwed or welded or fastened in a corresponding manner his.

At the top of the door 6 is a substantially plate-shaped door holder 11 with attached essentially U-shaped contour. In particular, the door holder 11 is included one leg rigidly connected to the top of the door 6, in particular screwed, while the other leg of the door holder 11 no fixed connection to the surface of the door. The door holder 11 is made of elastic material, in particular resilient plastic, so that the free door bracket leg 12 itself can move resiliently to the door. The door holder 11 is arranged such that the recess between the two legs 12 and 13 parallel to the front and Back of the door runs. As a result, the free door holder leg 12 can essentially move or spring perpendicular to the front and back of door 6.

As Figure 2 shows, the hinge pin 10 of the bearing block 8 with the resilient or movable leg of the door holder 11 in engagement. The door holder 11 instructs the door holder leg 12 has a hinge pin recess 14 in which the Hinge pin 10 is included (see. Figure 4). The hinge pin 10 occurs through the door holder 11 and is also in a slot-like bearing recess 15 out, which is provided in the top of the door 6. The Elongated hole 15 extends with its longitudinal axis substantially perpendicular to Front and back of the door so that the door 6 is perpendicular to its front and Back can move relative to the pivot axis 5. In other words, the hinge pin 10 can be moved back and forth in the elongated hole 15, the door holder leg 12 is also moved resiliently. The door holder leg 12 is arranged such that the hinge pin 10 to the end of the slot-like recess 15 is pressed towards the outside of the door 6 lies. The mobility of the door relative to the hinge pin and vice versa is in Figure 4 indicated by the arrow 16. The door holder 11 thus forms one at the same time Preload or spring device that the pivot axis 5 and the door 6 in one biased position to each other.

In an alternative, not specifically shown embodiment of the invention, it would also be possible to dispense with the slot-like training 15 and the hinge pin 10 only with the door holder leg 12. In this Fall would the hinge pin recess 14 in the door holder 11 essentially Sit concentrically on the hinge pin 10 without play. The agility would then not determined by the elongated hole 15, but by the spring movement of the door holder leg 12. Stops could limit the maximum deflection of the door holder leg Limit 12 in the direction of arrow 16.

As FIGS. 2 and 4 show, the door holder section rigidly attached to the top of the door forms 13 one projecting towards the inside of the door or towards the body 1 Cam 17, one on its side facing the device body 1 Has curve control surface 18. The cam control surface 18 is essentially from a first section in the form of a depression 19 and one continuous thereon subsequent second section in the form of a closed door to the device body 1 projecting convex curvature 20, which has a door opening section forms or acts as a door opener.

With the cam 17, an abutment pin 21 cooperates, which is parallel to the Hinge pin 10 is rigidly attached to the bearing block 8 (see FIG 3). The abutment pin 21 forms a sliding surface with its peripheral surface which can slide the cam control surface 18 of the cam 17.

The cam control surface 18 of the cam 17 and the abutment pin 21 are of this type arranged relative to each other and dimensioned that when completely closed Door of the abutment pin 21 nestling into the depression 19 on the cam 17th is applied. This is indicated in FIG. 5, in particular section a). In the completely closed position of the door 6 lies on the inside of the door circumferentially extending seal in the form of an elastic sealing bead 3 the sealing contact surface 2 of the device body 1 facing the door. Like Figure 5 shows, the seal 3 can have a magnet 4 in a manner known per se, of the metallic surface of the device housing or the outside of the Body 1 attracts and thus a secure, tight contact between the sealing contact surface 2 and the seal 3 causes.

If the door 6 is swung open from the closed position, the Curve control surface 18 of the cam 17 with its protruding toward the sealing contact surface 2 Curvature 20 come over the abutment pin 21. This is in Figure 6, particularly the section a) indicated. Since the cam 17 rigid with the door 6 is connected, this bulging of the curvature 20 presses on the abutment 21 the door 6 essentially perpendicularly away from the sealing contact surface 2. The Seal 3 is largely walk-free perpendicularly from the sealing contact surface 2 lifted. The hinge axis or the hinge pin 14 moves in the Elongated hole 15, as shown in Figure 6, against the spring force of the bias. The Door holder leg 12 is bent towards the fixed door holder leg 13.

If the door is stored further, the cam control surface 18 continues to run on the abutment pin 21 onwards. The curvature 20 goes back, so that the spring preload the resilient door holder 11, the door 6 back to its original position can press relative to the hinge pin 14. This is shown in Figure 7. As soon as the pivot axis 5 again assumes its starting position relative to the door the superposition of the translational movement of the door perpendicular to the swivel axis 5 ended. When the door is swung open further, it will experience a clean one rotary motion, as is common in itself. When swinging back into the closed position, the door undergoes a corresponding reverse movement. In particular, the seal 3 with its magnet 4 does not remain prematurely on the Sealing support surface 2 hang, rather the seal 3 is only towards the end of Closing movement moved essentially perpendicular to the sealing contact surface 2, namely when the cam 17 with its depression 19 on the counter bolt 21 snaps. Here occurs due to the spring preload by means of the elastic Door holder 11 an automatic closing movement that the door completely tightens. The spring preload tries the abutment pin 21 in the depression 19 press to reach a lower energy level of the system.

Instead of the integrally one-piece and elastically resilient design of the door holder 11 further embodiments are possible.

FIGS. 8 and 9 show such a further embodiment. Here too is the Hinge pin 10 in a slot-like bearing recess 15 in the top the door 6 out. The slot-like recess 15 also extends vertically to the inside and outside of the door so that the corresponding movement is achieved will, as has already been described. The door holder 22 is here, however formed in several parts. A first door holder section 23, the body of the device facing side is again formed as a cam 17, is rigid on the top the door 6 attached. The first section 23, which is substantially plate-shaped is formed, has on its side facing the outside of the door Drawer-like recess 26 in which the second door holder section 24 is displaceable is guided and arranged. The recess 26 extends with it Longitudinal axis parallel to the slot-like recess 15 in the top of the door 6, so that the second door holder section 24 transversely to the hinge pin 10 or at closed door substantially perpendicular to the sealing contact surface 2 in the first Door holder section 23 can be pushed back and forth. A spring 25 presses the second door holder section 24 towards the outside of the door 6. Defined a stop that z. B. be formed by a step of the recess 26 can, an end position of the second door holder portion 24, biased into the latter is.

In the second door holder section 24 is a circular hinge pin recess 14 provided with which the second door holder section 24 on the hinge pin 10 sits (Figure 8).

In order to move the door perpendicular to the pivot axis 5, the spring 25 is corresponding deformed, especially compressed according to Figure 9. Here drives the second door holder section 24 deeper into the drawer-like recess 26 in the first door holder section 23. The pivot axis 5 moves to the inside of the door out. In this version, too, the movement between the pivot axis 5 and door 6 transverse to the pivot axis depending on the pivot position controlled the door. The cam 17 acts analogously, so that on the preceding description is referred.

A further embodiment of the door holder is shown in FIG. 10, which is essentially the Execution according to Figures 8 and 9 corresponds. The door holder 27 shown here is also formed in two parts. The first door bracket section 28 is rigid with the door 6 connected, in particular as in the previously described embodiments on the Arranged top of the door. Its the device body 1 with the door closed facing side is formed analogously as a cam 17. Instead of the previously described Drawer-like recess 26, the door holder 27 has a longitudinal groove 29 open towards the top, in which the second door holder section 30 is longitudinal fits snugly and is guided in a longitudinally displaceable manner (FIG. 10). One in a spring pocket 31 of the first door holder section 28 seated spring 32 tensions the second door holder section 30 to the outside of the door. As with those previously described The hinge pin 10 can be implemented by the door holder 27 step through and engage in an elongated hole 15 in the top of the door 6. in the the rest of the function of the door holder 27 corresponds to that previously described Execution.

The additional axis of movement of the door perpendicular to the pivot axis 5 and at closed door perpendicular to the sealing pad 2 in connection with the cam device prevents the seal 3 from flexing. The seal 3 is always in the placed essentially vertically on the sealing contact surface 2 on the body 1 and lifted off again. Faulty sealing is avoided and the service life significantly extended as a result of the walk-free closing and opening processes.
