Description

The invention relates to a cooling and / or freezer with a body and at least one hinged Door, being the door a certain closing angle closes automatically.

Especially in the case of cooling and / or built-in furniture freezers it’s common practice so far a furniture or device hinge Use with built-in spring to close the door support. Here a spring with a constant spring force is used, that with a closing support small doors is often too strong when unloaded. With large doors in the loaded By contrast, the spring force is often not sufficient to condition the door automatic close. Incomplete locked doors with cooling and / or freezers have however according to that the energy consumption increases and z. B. the freezers build up icing. Alternatively, the springs used but with big ones Doors already been designed so that the doors close securely when loaded. This in turn leads to that these doors in the unloaded state due to the constant spring force slam too hard so that the door closes under a loud closing noise becomes.

In extreme cases, even the device itself can furniture body a built-in piece of furniture or the one in the door in a door rack stored goods damaged become.

The object of the invention is a Cooling and / or freezer of the generic type to develop in such a way that at a reliable and independent Conclude the door on the one hand minimizes the closing noise and on the other hand a vibration of the device or the one in the cooling and / or freezer stored goods is avoided.

According to the invention, this task is based from a cooling and / or freezer solved by the combination of features of claim 1. Therefore is based on a cooling and / or freezer according to the preamble of claim 1 at least one when closing the at least one door with this interacting damper intended. Such damping elements are in the furniture area already known. Various versions are commercially available. It can be a linear damper or a rotary damper act, here the damping hydraulic, pneumatic or via Friction can occur.

Through the built-in dampers the doors during the closing process braked or damped in the end position. This allows Shocks and resulting damage on the device, on the furniture, as far as the devices are installed, and on the stored goods in the door racks, for example Bottles, to be avoided. The closing noises are largely minimized.

Advantageous embodiments of the Invention result from the dependent claims following the main claim. Therefore can the at least one damper be directly or indirectly connected to the body. The damper can also be integrated in the at least one hinge.

For the case that the cooling and / or freezer from a furniture body is rebuilt, the damper on the furniture body be attached and interact with the cabinet door. In addition can with several damper installation options with different distances to door pivot (Adjustment of the lever arm ratios) the door braking force changed or the damper be adjusted. One to the door or to the device symmetrical damper installation is advantageous when changing the door stop.

Different requirements the damper, due to different door weights and Door closing speeds are caused; which depend on the user can, are ideally through the use of self-adjusting Shock absorbers automatically balanced.

According to an embodiment of the invention the damping through a in the door seal integrated damping mass respectively.

More details, advantages and Features of the invention are illustrated by one in the drawing embodiment explained in more detail.

Show it:

1 FIG. 2 shows a sectional illustration of a part of a cooling device according to the present invention,

2 : a representation of a hinge with locking support, as it can be used in the present invention and

3 : schematically a self-retracting device with integrated damper in two positions (a and b).

At the in 1 schematically illustrated cooling device 10 is a cooling device that is surrounded by a furniture body. The appliance door 12 is with a furniture door 14 coupled. The structure of the cooling device 10 with the appliance door 12 and the furniture door 14 corresponds to the known standard and therefore needs no further explanation here. On the lower edge of the appliance door 12 is a damper 16 arranged, which is designed here as a linear hydraulic damper. That damper 16 acts between the appliance door 12 and the cooling unit body 18 , When closing the furniture door 14 and the associated appliance door 12 dampens the shock absorber 16 the closing movement impressed by a spring-loaded hinge, not shown here in the illustration. A shock when you close the refrigerator door 12 can be safely prevented here. One or more dampers 16 can, in contrast to the embodiment shown here, also directly or indirectly in the furniture body be tegrated and against the furniture door 14 or the appliance door 12 Act.

In 2 a hinge joint is shown that the structure of the hinge DE 201 02 998 U1 is known to the same applicant. The hinge consists of a hinge part 20 which is screwed to a side wall of the cabinet housing when the hinge is used to link a refrigerator door. The hinge part 20 is bent from a sheet metal, in front of the web part 22 the side leg-like parts 24 are bent at right angles. The hinge part 20 has an angular shape, with an extension of the web part 26 is bent at right angles and the raised leg parts 24 limited.

On the aligned holes of the legs 24 riveted hinge pin 28 are between the thighs 24 the legs of a U-shaped curved lever 30 stored. Between that of the web part of the articulated lever 30 angled thighs 32 are on hinge pins 34 and 36 that in holes of the legs 32 are riveted, handlebars 38 . 40 pivoted, the other ends articulated with a pivotable hinge part 42 connected to the appliance door 44 is screwed. The pivotable hinge part 42 also consists of a U-shaped sheet metal part, between the legs bent from its web part 46 hinge pins 48 . 50 are held in holes in the legs 46 are riveted. On the hinge pin 48 is the other end of the handlebar 38 and on the hinge pin 50 the other end of the handlebar 42 pivoted. The handlebars too 38 and 40 consist of U-shaped sheet metal parts. On the handlebar 38 is a hinge pin between its legs 52 on which the rolled eye of a handlebar made of a flat sheet metal 54 is mounted, the other end also has a rolled eye, which is on a hinge pin 56 is stored in the holes in the legs 24 of the hinge part fixed to the body 20 is riveted. On a hinge pin 58 between the thighs of the handlebar 40 is held, and a hinge pin 60 between the thighs of the handlebar 38 is supported, are bearing parts for a compression spring 62 pivoted, the compression spring 62 is held on a pin of a bearing part which is guided displaceably in the other bearing part.

When pivoting the pivotable hinge part 42 the hinge pins approach the closed position 58 and 60 each other until they move away from each other after having passed through a dead center position, so that the compression spring 62 the pivotable hinge part 42 seeks to move into its closed position and holds it there.

To prevent the door from slamming into the open position after passing through the dead center position, the hinge pin is on the door 28 between the thighs 32 the articulated lever 30 a leg spring 64 supported. This leg spring 64 rests with one leg on a bolt 66 from, the ends of which in holes in the legs 24 of the hinge part 20 are riveted. The other leg of the leg spring 64 relies on an actuator only in the area of the open position 68 with which the web part of the articulated lever 30 is provided. Because of this leg spring 64 is in accordance with the cooling device according to the invention 1 not just damping when the appliance door is closed 12 through the appropriate damper 16 achieved, but also a damping when opening the door by the leg spring 64 , so that when the opening position is reached, a vibration of the cooling device is also prevented and thus both the device, the furniture body and the goods accommodated in the device are protected.

In 3 is an embodiment of a door self-closing, as it is known in principle, shown schematically. Here is a linear damper 70 in an assembly part 72 arranged. The door to be closed has a door pivot bearing in a manner not shown here. Via a driving pin 74 , which is arranged in a known and not shown manner on the appliance door, is in a guide groove 76 of the assembly part 72 guided locking part 80 against the force of a spring 78 deflected and locked in the tensioned state of the spring. When the door is closed, the locking part is unlocked and by the tension spring 78 pulled into the end position. The retraction and thus the door is damped with a linear damper.

Alternatively, for the linear damper too a rotation damper conceivable with gear. The rotary damper gear is here a guided rack, which is connected to the connecting part, operated.
