Abstract

The invention is based on a refrigerator with a door bearing for fastening a pivot-open door (2) of the domestic refrigerator. The door bearing has a fastening element (9), by means of which it is fastened on the housing (1) of the domestic appliance, and a bearing element (6), which is connected to the fastening element (9) via a bearing arm (3) and by means of which the door bearing engages in the door (2). According to the invention, when the door (2) is open, the bearing arm (3) is located in a position in which it is offset in height in relation to its rest position, which it assumes when the door (2) is closed.

Description

The refrigerator

The invention relates to a household refrigerating appliance according to the preamble of claim 1.

The bearings of the doors of household appliances such as refrigerators, freezers, microwaves or the like must be very stable on the one hand to keep the heavy weight of the doors, especially if they can be heavily loaded as in refrigerators. For aesthetic reasons, they should as far as possible not be visible, but disappear behind the door or the door. Furthermore, it is desirable to achieve the largest possible opening angle of the door to remove objects that are located inside the household appliance, as undisturbed as possible.

Door bearing as described in DE 197 23 077 A1, are covered with the door closed by this and are therefore not visible from the outside, but only allow a very limited opening angle. Even very complex constructions such as the integrated hinge described in DE 102 2005 021540 A1 do not exceed an opening angle of approximately 120 °.

On the other hand, freely pivoted bearings located above the door allow a maximum opening angle, but they are extremely ugly and make the household appliance appear cheap.

The invention has for its object to provide a visually appealing door bearing for a household appliance with maximum opening angle of the door.

The object is achieved according to the invention by a household refrigerating appliance with the features of claim 1. According to the door hinge for the household appliance door is constructed and attached to the household appliance that it at least partially lifts when opening the door from a rest position in which it is closed door in a swivel position, so that the mechanics of the door bearing when opening the door more space is available to stabilize the pivoting movement. In its rest position with the door closed, the area of the bearing arm that holds the bearing element on which the door is mounted is lowered, sinking into a niche provided for this purpose on the door or simply concealed behind the door panel. When the door is closed, the door bearing is therefore not visible to the user of the household appliance. When opening the door of the bearing arm is in the area where it overlaps with the door moved by more than its own height, thereby lifted out of the niche and thus freely movable.

As a result, the pivoting movement of the door is no longer limited by the door bearing, it is possible to open the door until it strikes the housing. As a result, an opening angle of more than 180 ° can be achieved.

In an advantageous embodiment of the invention, a lifting element, which presses the bearing arm of the door bearing when opening the door upwards on the door itself. The lifting movement of the door bearing is thereby effected directly from the door itself, there is no complicated translation or the like required.

Preferably, the door is chamfered laterally of the bearing arm, so that the bearing arm is pushed when opening the door along the slope and thereby pushed upwards. The slope can be reinforced because it is exposed by the movement of the bearing arm of an increased load.

The bearing arm is attached to the housing of the household appliance, wherein the housing or the attachment is formed so that it allows an upward and downward movement of the bearing arm. Preferably, a receptacle in the housing is provided for the movement of the bearing arm, which allows the bearing arm sufficient freedom of movement. In a preferred embodiment, the bearing arm is significantly longer than wide, so that it extends far into the housing and is anchored deep inside the receptacle. As a result, the distance between the anchoring of the bearing arm and the bearing element on which the maximum lifting movement must be performed is very large, so that the angular movement is kept very small during the stroke. Thus, the stroke of the bearing arm can be realized directly in a very simple manner, without complex parallel guides or other translations would be necessary.

Preferably, the recording penetrates up to 10 cm in the housing of the household appliance, so that a correspondingly long bearing arm can be fastened in it.

In a further preferred embodiment, the attachment of the bearing arm on the housing itself is movable. The fact that the bearing arm itself is movably mounted on the housing, resulting in a particularly durable construction that can be expected even after years of opening the door no breakages. Preferably, the fastening element is resilient, so that it supports the lifting movement of the bearing arm. Furthermore, the spring force of the spring element can be used to realize a latching connection between the spring element and the bearing arm, which the

Support arm on the housing holds. The bearing arm is simply pushed to close the locking connection during assembly on the spring element until its locking element engages the counter element of the detent spring. The detent spring presses with its spring force the bearing arm against the housing and thus closes the locking connection. As a result, on the one hand ensures an extremely simple installation of the door bearing, on the other hand, this creates a flexible attachment that leaves the stroke of the bearing arm enough play.

Preferably, the bearing arm is designed as a bearing angle. As a result, it is tipped between the housing and door as long as the door is closed, which gives the door bearing additional stability.

In a further advantageous embodiment, between the wall of the receptacle and the bearing arm in Hubbewegungsrichtung the bearing arm is a restoring element - A -

arranged, which presses the bearing arm with the door closed in its rest position, so that the bearing arm disappears in the door niche and is not visible to the front. This spring element is designed so that it counteracts the spring force of the resilient fastening element. Advantageously, the spring force of the spring element, which presses the bearing arm downwards can also be further increased, so that the lowering bearing angle is to be used as a closing aid for the door.

Furthermore, it is advantageous to attach a small lever on the bearing arm, which preferably rolls laterally during the up and down movement of the bearing arm and prevents the bearing arm rubs laterally on the housing. The lever thus directs the bearing arm in the transverse direction.

Further details and advantages of the invention will become apparent from the subclaims in connection with the description of an embodiment which is explained in detail with reference to the drawing.

Fig. 4 shows schematically a sectional view of a door bearing bracket and its

Fig. 5 schematically shows the portion of the door bearing bracket on which the wishbone engages in the housing of the refrigerator.

Figures 1 and 2 respectively show schematically the corner region of the housing 1 of a refrigerator and a corner portion of the door 2, which by means of a integrated bearing bracket 3 according to the invention is mounted on the housing 1 of the refrigerator, so the upper door storage area from the outside. While the bearing angle 3 is lowered when the door 2 is closed in a niche 4 located on the end of the door 2, it is lifted out of the niche 4 when the door 2 is opened and in doing so exits beyond the door panel 5. As a result, the bearing angle 3 is released, it only engages the attached thereto bearing pin 6 in the door 2, which allows a maximum pivotal movement of the door 2.

The lifting of the bearing angle 3 takes place during the pivotal movement of the door 2 through the door 2 itself. As soon as the door 2 is opened, the side wall of the niche 4 of the door 2 slides below the bearing angle 3. To simplify this, it can be seen in FIG. 3 once again shown a corner detail of the door 2 with the lowered into the niche 4 bearing angle 3 from a different perspective. Here, the side wall 7 of the niche 4 is clearly visible, which is formed as a slope to cause the lifting of the bearing bracket 3. At this slope 7, the bearing angle 3 moves up as soon as the door turns away from under him.

Fig. 4 shows a schematic sectional view of the bearing angle 3 with the arranged on it bearing pin 6 and the cutout of the housing 1 of the refrigeration device in which the bearing bracket 3 is attached. For fixing the bearing bracket 3, a chamber 8 is formed in the housing 1 in which the bearing bracket 3 engages. From the bottom of the chamber 8 from a detent spring 9 which has a locking receptacle 10 which engages with the locking lug 11 of the bearing bracket 3 at its end engaging in the chamber 8 a latching connection and thus fixes the bearing bracket 3 in the chamber 8. By its spring force, the detent spring 9 presses the bearing angle 3 in a raised position in the interior of the chamber eighth

This spring force of the detent spring 9 counteracts the spring force of a spring 12, which is arranged at the top of the bearing bracket 3. This spring 12 is formed as an opponent to the detent spring 9 and dimensioned in their spring force so that they Bearing angle 3 with the door closed in its rest position in the niche 4 at the door 5 presses. To stabilize the movement of the bearing bracket 3 laterally, a wishbone 13 is provided, which is laterally attached to the chamber 8. As can be seen in detail in FIG. 5, this transverse link 13 rolls laterally during the upward and downward movement of the door angle 3 and thus prevents a lateral pivoting movement of the door angle 3, which could lead to damage to the chamber 8.
