Description

DESCRIPTION

Household appliance, in particular cooling apparatus and / or freezing apparatus

The present invention relates to a domestic appliance, in particular cooling apparatus and / or freezing apparatus having all the technical characteristics of independent claim 1. Household appliances, in particular refrigeration appliances and / or freezing appliances are subject to at the most diverse ambient temperatures and are equipped in different ways with possibilities of trays and containers. These trays and containers, such as shelves or drawers, can be used for this purpose in the different temperature storage areas of the refrigerating appliance and / or freezing apparatus, for example in the refrigeration zone or in the freezing zone, and the most diverse humidities of the air in the internal space and the respective applications as for example storage of vegetables or wine. Such trays and containers are often made transparent for functional or optical reasons or provide the user at least partially, eg as in the use of racks, a view of the cooling space.

For handling reasons, extraction paths are frequently provided, on which these trays and containers are housed. In this sense, a pushing element is usually housed in two extraction rails which are fixed in opposite side walls of the internal container of the domestic appliance, so that the tray or the container can be extracted from the domestic appliance, in particular from the refrigeration appliance and / or freezing device on the extraction rails.

In this sense it has already been proposed to associate push elements with a shock absorber and / or a self-retracting element to improve handling. The movement of the pushing element is executed in this direction in the last zone of the closing operation by means of the damper system and self-retracting element in an autonomous and slow manner until the final position.

In known domestic appliances in which extraction rails with self-retracting and / or damping elements are provided, the self-retracting element or damping are arranged between the internal appliance wall and the drawer or below the drawer or partially or fully behind of the drawer. This, however, damages the existing storage space, the optical impression and the possibility of cleaning the domestic appliance.

WO 2004/098350 A1 discloses a self-closing telescopic mechanism for a drawer slide which can be used in a refrigerator. Document DE 10 2005 021591 A1 relates to a cabinet-type domestic appliance whose housing has an internal space, in which a support can be moved with the aid of a telescopic guide. The document EP0718574 A1 is considered as the closest state of the art and discloses the technical characteristics of the preamble of independent claim 1. The object of the present invention therefore to facilitate is a household appliance, in particular a refrigeration appliance and / or freezing apparatus in which a space-saving incorporation of a damping and a self-retracting element is possible.

According to the invention, this object is solved by a domestic appliance, in particular a cooling apparatus and / or freezing apparatus according to claim 1.

The domestic appliance according to the invention has in this sense a pushing element that can be inserted in an internal container of the domestic appliance, and a self-retracting element associated with the pushing element and a damping associated with the pushing element. According to the invention in this regard, it is provided that the self-retracting element and the damping are mounted at least partially embedded in a depression.

Advantageously in this respect, the self-retracting element and / or the damping are assembled or can be mounted flush with at least 50% of its width and advantageously completely in the depression. By means of the depression, a self-retracting element or a damping of an extraction rail can be mounted recessed, without or almost without limiting the storage space in the cooling zone itself. Furthermore, the optics are considerably improved since a complete coating of the self-retracting element or of the damping is possible. At the same time cleaning of the domestic device is possible essentially without disturbing edges in this zone.

The self-retracting element and / or the damping can in this way form an element of the extraction mechanism and in particular cooperate with an extraction rail. Particularly in this sense, in a pull-out rail, a driver is arranged, which cooperates with the self-retracting element and / or the damping and in particular in the insert becomes engaged with the self-retracting element and / or the damping. As an alternative, however, the self-retracting element and / or the damping can also form an element separate from the usual extraction mechanism and cooperate directly with the push element or be connected to it. In this case, a pusher can be arranged in the pushing element.

The domestic appliance according to the invention has an internal wall of apparatus having a depression, in which the self-retracting element and / or the damping are mounted at least partially recessed. In this sense, the recessed mounting of the self-retracting element and / or of the damping has the advantage that drawers or shelves already present do not have to be additionally adapted to the new extraction mechanisms

Advantageously according to the invention, a mounting rail is provided on which the rail is fixed or can be fixed. of extraction and / or self-retracting element and / or damping. The assembly of the extraction rail through a mounting rail makes it possible to fix it considerably easier. In addition to the same internal device wall or an identical depression of the internal device wall and different mounting rails, a simple adaptation to different extraction rails can be effected.

Advantageously, the mounting rail is arranged on the internal wall of the apparatus, the extraction rail being fixed or being able to be fixed on the mounting rail.

Advantageously, the mounting rail has in this sense a depression or recess in which the self-retracting element and / or the damping, in particular the self-retracting element and / or the damping of the extraction rail, are mounted or can be mounted partially embedded. The self-retracting element and the damping are therefore at least partly in the depression or recess of the mounting rail, the depression re-entering the depression of the internal device wall. The depression in the mounting rail is closed in this direction advantageously towards the internal wall of the device. As an alternative, however, the self-retracting element and / or the damping of the extraction rail can also pass through an open recess towards the depression in the internal wall in the mounting rail.

The mounting rail can advantageously be fixed on the internal wall of the device. In particular, the mounting rail has a snap connection at the rear part with which it can be fitted into the depression in the internal wall of the device.

In addition, advantageously, the extraction rail or the mounting rail is integrated by foaming into the depression of the internal device wall. The integration by foaming of the extraction rail or of the mounting rail, on which the extraction rail is fixed, increases in this respect the stability of the connection between the extraction rail and the internal appliance wall.

Advantageously, the depression of the inner device wall has foam openings through which, during foaming of the insulation, foam enters in the area between the internal side of the depression and the extraction rail or the mounting rail. For this reason, the foaming integration of the extraction rail or the mounting rail can be carried out in one step by foaming the insulation between the internal wall of the appliance and an external device wall.

Advantageously according to the invention, the depression of the internal device wall is embedded. As a result, the internal wall of the device can already be equipped with the depression in accordance with the invention when a self-retracting element and / or a damping of an extraction rail are mounted or can be mounted at least partially recessed.

In addition, advantageously for the case that foam openings are provided for the integration by foaming of the extraction rail or of the mounting rail, also the foam openings are recessed. Therefore, the depression can be manufactured with the foam openings in one step together with the internal wall of the device. Advantageously, the self-retracting element and / or the damping of the extraction rail are arranged or can be arranged between two fixing areas disposed one behind the other in the direction of extraction for the extraction rail. This makes it possible to incorporate the self-retracting element and / or the damping element equally as well as space-saving as well as affordably. Advantageously in this respect in particular the depression, in which the self-retracting element and / or the damping can be mounted, is arranged between two fixing areas for the extraction rail. Advantageously, the extraction rail can be fixed in this direction in the fixing area by means of flanges, click fasteners or screw connections.

In addition, advantageously, the depression of the internal device wall extends along a side wall of the internal device wall in the direction of removal. The longer expansion of the depression therefore runs along a side wall of the internal device wall in the direction of extraction, so that a correspondingly oriented self-retracting element mechanism can be mounted in this depression and / or extraction rail absorber.

Advantageously according to the invention, it is provided that the depression or recess in the mounting rail and / or the internal device wall extends only through a partial area in the direction of removal. This has the advantage that in the remaining area, mounting areas can be provided for mounting the extraction rail. These mounting areas do not have to be arranged recessed, or only to a lesser extent, in the internal wall of the apparatus or in the mounting rail since in this case the width of the mounting rail is not increased by the shock absorber or the mounting element. self-retraction Advantageously in this sense the partial zone is arranged with the depression or recess between two mounting areas for mounting the extraction rail. This makes possible a stable assembly of the extraction rail with a zone arranged between the mounting areas for the arrangement of the shock absorber and / or the self-retracting element.

In addition, it can be provided that the depression of the internal device wall extends essentially over the entire length of the mounting rail and / or of the extraction rail along a side wall of the internal wall of the apparatus in the direction of removal. Particularly in the use of a mounting rail this has the advantage that it can be connected in a simpler and more stable manner to the internal wall of the device. The mounting rail then advantageously has a correspondingly shorter depression or recess to make room for mounting areas.

Advantageously, according to the invention, a cover covering the depression is provided. The incorporation of the self-retracting element and / or the damping of the extraction rail according to the invention at least partially recessed makes possible in this sense a simple coating of this part of the extraction rail by means of the cover, which makes possible a simplified cleaning in mostly without annoying edges in this area.

Advantageously, the cover covers in this sense the depression or recess of the internal device wall or of the mounting rail when the extraction rail is mounted.

In an advantageous configuration the cover can be moved with the extraction rail and / or the self-retracting element and / or the damping. For this reason, in particular for the connection of the self-retracting or damping element arranged in the depression, which can be moved in the direction of removal with the pushing element, no oblong hole must be provided, through which dirt can penetrate into the area. of depression. Rather, the depression can be completely covered by the cover that can be displaced with the self-retracting element and / or the damping. Advantageously, the cover has in this sense a connecting element with the pushing element which cooperates, for example, with a driver and thus transmits the force of the self-retracting element and / or of the damping towards the pushing element.

Alternatively, the cover can also have a sealing skirt or flexible sealing film through which a connecting element passes between the self-retracting or damping element and the pushing element.

The domestic appliance according to the invention, in particular cooling apparatus and / or freezing apparatus, is advantageously designed so that according to the specific requirement, different extraction rails can be incorporated.

The present invention also comprises a domestic appliance, in particular cooling apparatus and / or freezing apparatus with at least one extraction rail with self-retracting and damping element, in which the self-retracting element and the damping of the extraction rail are assembled at least partially embedded in the depression of the internal wall of the apparatus. Advantageously in this respect, the self-retracting element and / or the damping are embedded in at least 50% of its width and also advantageously completely in the depression of the internal wall of the built-in appliance.

Advantageously, the domestic appliance, in particular cooling apparatus and / or freezing apparatus, has in this sense a drawer and / or a tray that is mounted on two extraction rails. The extraction rails are advantageously mounted in this direction on opposite side walls of the domestic appliance.

The different load profiles and requirements, eg depending on the size of the drawer and the load allowed for it, require different demands on the damping force and self-retraction in this regard. According to the invention, it can be provided that a damper and a self-retracting element are provided in both extraction rails. As an alternative, however, only one damper and one self-retracting element can be provided in one extraction rail, while the other extraction rail is made without a damper and without a self-retracting element. In addition, only one self-retracting element and two shock absorbers or two self-retracting elements and only one shock absorber can be used. The depression according to the invention allows in this sense a smooth incorporation of all these variants, without having to be provided different internal walls. The drawer or the shelf are accommodated in this direction above two extraction rails in the domestic appliance, in particular cooling apparatus and / or freezing apparatus, the extraction rails being mounted on opposite side walls of the internal wall of the appliance. .

In the case of the extraction rail it can be a discretionary telescopic guide, eg a simple extendable guide, a fully extensible guide or extendable guides fitted in others. The extraction rail can be implemented in this direction in a discretional manner, eg with spheres or rollers.

Advantageously, an extraction rail is fixed or can be fixed to the internal wall of the appliance of the domestic appliance, the internal wall of the appliance having a depression, in which the extraction rail is mounted at least partially recessed. By means of the recessed mounting of the extraction rail, the storage space is increased in the internal container of the domestic appliance. An optically attractive and easy to clean surface design is also possible.

The depression must be designed in this sense at least in the area of the extraction rail open forward, so as not to prevent the extraction of the pushing element.

Advantageously, the domestic appliance is made in this sense in the manner already illustrated above. In particular in this regard, it is provided that the extraction rail is mounted together with a self-retracting element of a damping, at least partially recessed in the depression of the internal device wall. The self-retracting element and / or the damping can be mounted in this direction above or below the extraction rail in the depression. As an alternative it can be foreseen that the depression for the extraction rail there is an even deeper area, in which the self-retraction element and / or the damping is arranged.

Advantageously, the additional depression in this direction is arranged in an internal device wall. The present invention also comprises a domestic appliance, in particular cooling apparatus and / or freezing apparatus, in which the depression is arranged in the thrust element, in particular in the bottom area of the thrust element. The self-retracting element and / or the damping are thus arranged in the thrust element, advantageously in a notch arranged in the back ground region. The entire arrangement is incorporated in this embedded sense and is thus protected from damage.

As an alternative, the depression may be arranged in an area of the domestic appliance disposed below the thrust element, in particular in an underside of the bottom-mounted thrust element, cover or inner container section. The self-retracting element and / or the damping are therefore arranged below the thrust element, advantageously in a depression arranged below the back ground area. The entire arrangement is incorporated in this embedded sense and is thus protected from damage.

The self-retracting element and / or the damping can be arranged according to the invention in the center with respect to the pushing element. Therefore, an introduction of central force occurs, which makes a more uniform movement possible and prevents a blockage.

Advantageously, according to the invention, a drive element is provided which cooperates with the self-retracting element and / or the damping element, the driving element engaging the insertion of the thrust element with the self-retracting element and / or the damping element and releasing it during removal. of the push element. Such an activator can fit into the self-retracting element, initiate this and transmit the forces generated by the self-retracting element.

If the self-retracting element or the damping element is arranged in the pushing element then the driving element is advantageously arranged in a stationary area of the domestic appliance, in particular below the pushing element, in particular in a bottom, lid or section internal container arranged under the push element. If, on the other hand, the self-retracting element or the damping is arranged in a stationary area of the domestic appliance, then the trailing element is advantageously arranged in the pushing element.

The present invention further comprises an internal wall of apparatus for a domestic appliance, in particular a cooling apparatus and / or freezing apparatus, as already illustrated above. The internal device wall comprises in this sense a depression, in which a self-retracting element and a damping of an extraction rail at least partially recessed can be mounted in case of demand.

The present invention further comprises a thrust element for a domestic appliance, in particular a cooling apparatus and / or freezing apparatus, as already illustrated above. In particular, the thrust element comprises in this respect a driver or a depression, in which a self-retracting element and / or a damping of an extraction rail at least partially recessed can be mounted in case of demand.

The present invention further comprises a self-retracting element and / or a damping for a household appliance, in particular a refrigeration appliance and / or freezing appliance, as already illustrated above.

The present invention further comprises a method for manufacturing a household appliance, in particular a cooling appliance and / or freezing appliance with the following steps: providing an internal appliance wall with a depression, in which an element can be mounted self-retracting and / or cushioning of an extraction rail at least partially recessed, selecting an extraction rail with a self-retracting element associated with the thrust element and / or a damping associated with the thrust element, as well as mounting the extraction rail on the internal wall of the device. If an extraction rail with a self-retracting element or with a damping element was selected, then the self-retracting element and / or the damping of the extraction rail are mounted at least partially embedded in the depression. The method according to the invention thus makes possible the simple and affordable manufacture of a household appliance, in particular of a cooling apparatus and / or freezing apparatus with an extraction rail, having a self-retracting element and / or a damping, or with an extraction rail without a self-retracting element of this type or without a damping of this type. Therefore, for different extraction systems, no more different side walls have to be foreseen. In addition, for different extraction systems, advantageously different drawers or shelves must also be provided. Advantageously in this respect, the self-retracting element and / or the damping of the extraction rail are mounted with at least 50% of its width, and advantageously completely embedded in the depression.

Advantageously, the internal wall of the device with the depression according to the invention is provided in this way by means of drawing the internal wall of the device and the depression. For this reason, the internal wall of the apparatus can be manufactured with the depression without problems in a single stage.

In addition, an insulation between the inner device wall and an external device wall is advantageously provided by filling with foam.

In addition, according to the invention, the extraction rail assembly is advantageously carried out by means of a mounting rail, which is installed in the depression of the internal wall of the apparatus, the extraction rail being fixed in the rail. mounting.

A mounting rail of this type enables a simple assembly of the extraction rail. Advantageously in this sense, according to the embodiment of the extraction rail, different mounting rails are used. In particular, depending on whether a damping and / or a self-retracting element is used, assembly rails with or without depression or recess can be used.

Advantageously in this respect according to the invention, the mounting rail is integrated by foaming into the depression of the internal device wall. Advantageously, for this purpose, the mounting rail is initially inserted into the depression and engaged through a click connection. Subsequently, the integration by foaming through foam openings in the depression of the internal device wall is advantageously carried out in one step with the facilitation of the insulation between the internal wall of the appliance and the external wall of the appliance.

Figure 11: a perspective view is diagonally from above a drawer as well as a stationary area of the domestic appliance according to the invention shown in Figure 10.

In figures 1 to 3 a refrigeration apparatus and / or freezing apparatus according to a first embodiment is shown. In this sense figure 1a and 1b show a perspective view of the cooling space and / or freezing space of the cooling apparatus and / or freezing apparatus according to the invention according to the first embodiment. The arrangement of the extraction rail is shown in this respect in Figures 2 and 3 in each case in sectioned views.

The cooling apparatus and / or freezing apparatus has an internal wall of apparatus 1 which forms the cooling space container and / or freezing space container. In addition, an external device wall 2 is shown, which is connected to the internal device wall in a connection area. An insulating layer is created between the outer device wall 2 and the internal device wall 1 by foam filling the area between the external wall of device 2 and the internal wall of device 1.

An extraction rail 3 is mounted on the left side wall shown on the internal wall of the apparatus 1, on which a drawer or a shelf can be removably mounted. The extraction rail has in this sense a damping and / or a self-retracting element 7.

According to the invention, a depression 6 is provided in the internal wall of the apparatus 1, in which a self-retracting element and / or a damping 7 of the extraction rail 3 are mounted in a recessed manner.

The extraction rail 3 is mounted in this direction in the first exemplary embodiment via a rail assembly 4 on the side wall of the internal wall of the device 1. The mounting rail 4 is mounted in this direction in the area of the depression 6 in the internal wall of the device 1. Furthermore, the mounting rail 4 has an additional depression 16 in which the self-retracting element and / or the damping of the extraction rail 3 are mounted recessed. The depression 16 is covered in this direction by a cover plate 5. By means of the depression 6 according to the invention in the wall internal of the device the self-retracting element and / or the damping of the extraction rail 3 can be mounted completely embedded in the internal wall of the apparatus. This is done by mounting the self-retracting element and / or the damping in the depression 16 in the mounting rail, the recess 16 being mounted in the mounting rail, which is recessed in the recess 6 in the internal wall of the device 1.

This arrangement is shown in this sense in Figures 2 and 3 in each case in sectioned views. The extraction rail in the exemplary embodiment is realized as a telescopic guide with an extendable tray guide 12 and an extensible mounting guide 14. These are connected by means of an additional extensible guide 13. In this sense a drawer 10 is located through a cantilever 11 on the extendable tray guide 12 while the extraction lane is mounted through the extendable mounting guide 14 on the internal appliance wall. In this sense, a damper and / or a self-retracting element 7 are provided which are connected to the extraction rail 3. The damper and / or self-retracting element is arranged in this direction together with the extensible mounting guide 14 in the depression 6. .

The damper dampens the movement of the extraction rail in this direction in the end area of the insert. The self-retracting element causes an automatic retraction of the extraction rail to its zero position in the end area of the movement. For example, the self-retracting element has a spring which is tensioned when the extraction rail is removed and the insertion of the extraction rail provides an automatic self-retracting element.

The assembly of the extraction rail is carried out in this respect according to the invention by means of the mounting rail 4. The mounting rail 4 has a depression 16 in which the self-retracting element and / or the damping 7 are mounted completely flush-mounted. The depression 16 is covered in this direction by the cover 5. The mounting rail 4 is mounted in the depression according to the invention 6 on the side wall of the internal wall of the assembled device. Therefore, the depression 16 of the mounting rail 4 is located within the depression 6 of the internal wall of the device.

The mounting rail 4 is assembled in this way because it is inserted into the depression 6 in the internal wall of the device and is fixed by a snap connection 8. The recess 6 has connecting elements by snap-fit corresponding to cooperate with fitting elements in the mounting rail 4. Then the mounting rail 4 is integrated by foaming into the internal wall of the apparatus. For this purpose, on the back side of the depression 6, foam openings 17 are provided through which, during foam filling of the mounting side wall, also the area 9 between the depression 6 of the internal appliance wall and the rear side of mounting rail 4 is filled with foam. The mounting rail 4 has in this direction a groove 18 on the rear side which is surrounded by foam during the foam application process. For this reason, an even stronger connection with the internal wall of the device is possible.

As can be seen in particular from FIG. 3, the depressions 6 and 16 run in the direction of extraction along the internal wall of the apparatus. The depression 6 extends in this direction essentially over the entire length of the mounting rail 4 or of the extraction rail 3. Thus the mounting rail can be foamed all over its rear side with the depression 6. On the other hand the depression 16 for the The housing of the self-retracting element or of the damping 7 extends only through a partial area of the expansion of the mounting rail in the direction of removal, so that space remains for the mounting areas 15. The depression 16 is arranged in this direction between two fixing zones 15 for fixing the extraction rail 3. In these fixing areas 15 the extraction rail is connected to the mounting rail 4, eg by means of a screwed connection or a recessed connection.

In figures 4 and 5 a second embodiment of the present invention is shown, in which the extraction rail 3 is mounted directly on the internal wall of apparatus 1. The extraction rail 3 has in this sense an extendable rail tray 31 on which a shelf 30 is disposed. Extendable tray guide 31 is housed through a ball-bearing strip on an extendable mounting guide 32. Extendable mounting guide 32 of extraction rail in the second example of embodiment is mounted between two projections 33 on the side wall of the internal wall of apparatus 1. The protrusions form in this sense a housing for the extraction rail 3.

In the central and rear area, the extraction rail 3 or its extensible mounting guide 32 are thereby arranged in a recessed manner. On the front side, the extendable mounting guide 32 is nevertheless aligned with the side wall region 34 of the front side, so that the extendable tray guide 31 can in this case be removed from the extensible mounting guide 32.

The extraction rail 3 has a self-retracting element 7 damped. This is arranged according to invention in a depression 6 of the internal wall of the apparatus. The depression 6 is countersunk in this direction on the side wall of the internal appliance wall between an anterior and a rear mounting area for the extraction rail 3. In the extraction direction, therefore in the area of the extraction rail 3 initially a mounting area of the internal appliance wall is provided that is aligned with the side wall area 34 on the front side. The depression 6 is then connected to this mounting area. A mounting area, which is aligned with the first mounting area and the inner wall area 34 on the front side, is again connected to the depression 6.

In the second embodiment, the extraction rail 3 is fixed directly on the internal wall of the apparatus 1, without a mounting rail being provided. In addition, the self-retracting element or the damping 7 is located directly inside the depression 6 of the internal wall of the apparatus. The depression 6 in the internal wall of the apparatus 1 has in this regard in the embodiment only an opening towards the internal space of the device, instead it is closed with respect to the insulation layer 20. The area between the walls of the depression 6 and the damping or self-retracting element 7 is therefore not applied with foam.

The depression according to the invention in the internal wall of the apparatus makes it possible to place the shock absorber with the self-retraction element not between the side wall and the drawer or the shelf, but completely or mainly in the depression in the side wall of the device. the zone of refrigeration and / or freezing. In the embodiment according to the invention it is advantageous that the useful content is not reduced or at least not essentially. In particular, a drawer or a shelf, which can be pulled out through the extraction rail, does not have to be reduced, as was still necessary in the state of the art to create sufficient space for the damper or self-retracting element. Rather, the damper or the self-retracting element can be arranged by saving in the depression in the side wall. It is also advantageous that, by incorporating the damper and the self-retracting element in the side wall depression, they can be completely or mostly covered without an annoying design, so that after cleaning the drawer or shelf a cleaning is possible for the most part part without annoying edges in this area. The incorporation into the depression in the side wall is advantageous especially in the case of transparent or translucent drawers or shelves to offer an improved optical impression. It is also advantageous that existing drawers or shelves do not have to be modified constructively, or not essentially due to the recessed incorporation of the damper or the self-retracting element and these incorporated elements do not collide with food.

The depression in the side wall is ideally located between two zones for fixing the extraction rail. However, a depression is also conceivable above or below the rail for extracting or attaching the extraction rail or behind an extraction rail fixing area.

As already described, the extendable guide can be fixed by means of a fastening rail in the side wall fastening, the fastening rail integrating by foam with the side wall. In this respect, the fixing rail is advantageously designed as an injection molding part. In this respect, the fastening rail advantageously has a depression between two regions for fastening the extraction rail and thus the space required for the damping and the self-retraction element. As an alternative, by means of a corresponding construction of the fixing rail and a corresponding arrangement of the depression of a fastening rail, an insertion above, below or behind a fixing area would also be possible.

The fastening rail made as an injection molding part for fixing the extraction rail can be locked before the foam application process in the depression in the side wall and be held there by the foam pressure without screw connection. By means of the foam opening in the region of the depression in the internal wall of the apparatus, it is possible to foam-fill the groove of the mounting rail on the rear side. This has the advantage that the mounting rail is still better connected to the side wall of the domestic appliance and that by means of the additional foam a better insulation is achieved. To this end, the mounting rail advantageously has a groove which is filled with foam. The foam filling of the side wall and of the area between the depression and the rear side of the mounting rail is carried out in this direction in a working step, whereby a foam outlet can also be avoided without additional sealing means.

Since the different loads and profiles of demand depending on the size of the drawer and the load allowed for this impose different demands on the damping force and the force of the self-retracting element, it can be done by incorporating different extraction rails a corresponding adaptation . A drawer or a shelf are usually accommodated in this way by means of two extraction rails on the right and on the left on the internal walls of the domestic appliance, in particular cooling apparatus and / or freezing apparatus. In this sense, both extraction rails can be provided with a damper and a self-retracting element. As an alternative, only one extraction rail with a self-retracting element and a damper can be provided, while in the other extraction rail the buffer and the self-retraction element are dispensed with. However, depending on the demand, a damper and a self-retracting element can also be provided in one extraction rail, in the other extraction rail only a buffer or only a self-retracting element.

Advantageously according to the invention, it is provided that the extensible guide with shock absorber and / or self-retraction including fixing parts consists of materials allowed for food and / or materials with neutral odor.

Furthermore, a drawer, as shown in the first embodiment, can be mounted directly on the extraction rails. Alternatively, as shown in the second embodiment, it is also possible to initially mount a support plate on the extraction rails. On this support plate a drawer or another container can then be arranged according to the demand. A support plate mounted on the extraction rail can, however, also be used without a drawer as a removable bottom. The support plate may be composed, for example, of glass or plastic.

According to the invention, by means of the depression in the internal wall of the apparatus, an incorporation of more affordable and more space-saving extraction systems with a self-retracting and / or damping element is provided, which also has optical and hygienic points of view. considerable advantages. In this sense, the self-retracting element or the shock absorber of an extraction rail can be partially or completely assembled in the depression according to the invention in the internal wall of the apparatus. According to the invention, however, it is also possible to incorporate an extraction system without self-retracting element but with damping or with an extraction system without self-retracting element and without damping in the same internal wall of the apparatus. In particular, the embodiment is made in this way in a mounting rail, which is integrated by foaming into the depression in the appliance wall. As an alternative, however, the assembly can also be carried out directly on the internal wall of the apparatus.

It is also conceivable to install a damper and / or a self-retracting element in a telescopic rail system, which is mounted on a support plate. A system of telescopic rails mounted on a support plate is shown in this regard in WO 2006/048307 A1, the content of which is the subject of the present application by reference in all its contents. In the telescopic rails shown in this document, which are mounted eg on a glass plate, a damper and / or a self-retracting element can now be installed.

It is also conceivable to employ a shock absorber and / or a self-retracting element in synchronized telescopic rail systems in which the left and right telescopic extension rail are connected, for example by means of a connecting rod with, for example, a toothed wheel and Zipper over the telescopic rail. In certain arrangements a central shock absorber incorporation with self-retracting element is also conceivable. In figure 6 there is shown a third embodiment of a domestic appliance according to the invention, in which an extraction rail 42 is mounted embedded in a depression 41 of the side wall 40 of the domestic appliance. The extraction rail 42 is recessed in this direction, seen in the width direction of the domestic appliance, completely in the depression 41. The depression 41 can be formed in this direction by a recessed area of the internal container of the domestic appliance. In this sense, the depression 41 can also be embodied as a separate element which is fixed to a depression of the internal container, as shown in the first exemplary embodiment.

Furthermore, in the exemplary embodiment, a self-retracting element 43 is provided, which can be made with or without damping. Instead of the self-retracting element, only damping can also be provided. Also the self-retracting element 43 or the dampers are mounted in this direction in the depression. In the third exemplary embodiment in this way the entire extraction mechanism is located hidden in the inner container wall. By means of this form of built-in construction, an essentially larger storage space is possible. The depression 41, however, must be open in the forward removal direction so as not to hinder the extraction rail 42 at the outlet.

The depression 41 is covered by a protective cover 46 which thus prevents it from becoming dirty and prevents a direct view of the extensible guide and the self-retracting element, whereby attractive optics are achieved. By means of the exemplary embodiment according to the invention, damage to the extraction mechanism can be prevented since the self-retracting element or the shock absorber is no longer accessible to the user. Also the extraction rail 42 can be reached only outside the cooling apparatus in the extracted state. In this sense both the extensible guide and the self-retracting element or the damping are mounted on an element comprising the depression 41, which forms a retaining part. For the recessed mounting the retaining part is embedded in the inner container wall 40.

The drawer 44 has a base 45 which produces a connection with the extraction rail 42 and which is so wide that it goes into the depression 41. Advantageously, the self-retracting element 43 or damper is actively connected in this direction directly with an extraction element. of the extraction rail 42. For the assembly of the drawer 44, only the base 45 must be mounted on the extraction rail 42.

An additional advantage of the solution shown in Figure 6 is the compact structure. All the constructive elements for the functions that serve for the extraction and introduction of the pushing element are installed in the retaining part. This makes possible a separate assembly of this assembly unit, the functional test of the assembly unit before assembly on the apparatus and easy handling during incorporation into the apparatus. In particular, the depression 41 can be realized in this sense as a mounting rail, which is mounted on the internal wall of the container.

Advantageously in this regard, extraction rails 42 mounted in a recess are provided on both sides of the pushing element, such as these are shown in FIG. 6 only for one of the sides. As already illustrated, neither a self-retracting element 43 nor a damper has to be provided on both sides.

In the embodiments shown above, the self-retracting element or the damper forms a part of the extraction rail arrangement or acts directly on the movement of the extraction rail. The self-retracting element or the damping therefore acts only indirectly through the extraction rail in the movement of the pushing element.

The present invention is, however, not limited to such embodiments. Rather the damping or the self-retracting element can also form a separate element, which does not act through the extraction rail, but through a driver in the movement of the pushing element. In this sense, the damping or the self-retracting element in a first variant can be arranged in the pushing element, while the trailing element is arranged in a stationary element of the domestic appliance. In a further variant, on the other hand, the driver is arranged in the drawer while the damping or the self-retracting element is arranged in a stationary element of the domestic appliance.

In FIGS. 7 to 9, push elements according to the first variant in which a self-retracting or shock-absorbing element 51, 61 is integrated in the pushing element 50, 60 are shown in this direction. In this sense, in the pushing element there is a depression is provided, in which the self-retracting element or the damping is mounted recessed. In this sense again a self-retracting element with or without damping can be used, or also only a damping.

In the variants of embodiment shown in figures 7 to 9 of the present invention, the self-retracting element or the damping is housed in a drawer. However other pushing elements such as plates are also conceivable.

The self-retracting element 51, 61 or the damping are located in this direction in a notch in the rear area of the pushing element 50. The recess thus forms a depression, in which the self-retracting element or the damping is mounted recessed. The entire self-retracting element or shock absorber is located recessed and is thus protected from damage. By means of a translucent embodiment of this area, for example, the self-retracting or damping element can be hidden in this direction.

The assembly of the self-retracting element or damper can take place in this respect, for example by means of retaining hooks, so that the self-retracting or shock-absorbing element can be simply inserted into the depression and there interlocked in its final position. Dismantling can then be advantageously carried out only by the customer service department with a tool.

The placement of the self-retracting element or shock absorber can happen in this direction to the left, to the right or in the center. The placement in the center, as shown in figure 7, offers in this sense the advantage that the introduction of force takes place in the center. The drawer rolls in a uniform and straight way, preventing a tilting, especially in the case of full load.

As an alternative, however, an arrangement of the self-retracting element as in FIG. 8 to the left and / or to the right in the pushing element 60 is also conceivable. The self-retracting element 61 or the damping can be arranged in this direction for example in FIG. an edge area of the drawer below the extraction rail 62.

In this sense, a drive element 62 is provided which engages in the self-retracting element 61 or damper, when a retraction element 61 is used to initiate this. The drive element engages in this direction in the self-retracting or shock absorbing element and absorbs the tensile or pressure forces. In this way, the pulling element is advantageously unlocked during the removal of the self-retracting or shock-absorbing element and thus makes possible a free extraction movement in the remaining area of the extendable guide.

The drive element 62 is arranged in a corresponding stationary area of the household appliance. The Drag element forms, when a self-retracting element is used, the trigger for this self-retracting element. On the other hand, if only one shock absorber is used, it can also be a single stop element in the case of the drag element.

The drive element can be designed as an integral element of another component, for example as a hook in a lid. However, the drive element can also be embodied as a separate component, for example as a support part with retaining hooks, which is inserted into the bottom of the inner container.

Advantageously in this sense, the drive element in the domestic appliance forms a projection, which engages in a recess in the self-retracting or damping element and thereby transmits the forces from the moving part of the self-retracting or damping element to the element of push.

The self-retracting element offers the customer greater comfort and the drawer rolls after the self-retracting element is locked in a smooth and silent way by itself.

As shown in FIGS. 7 to 9, the self-retracting element can be arranged in this direction in the bottom area of the thrust element. The driving element 62 is then arranged in a corresponding stationary area of the domestic appliance, that is to say under the drawer for example an intermediate bottom, a cover or the bottom of the inner container.

The self-retracting element or the damping is advantageously embedded in this direction in the bottom area of the pushing element so that the pushing element, after removal of the household appliance, can be deposited without any problems on a flat surface. Advantageously, the surface of the pushing element in the region of the damping or of the self-retracting element forms a flat surface without troublesome edges.

A readjustment of a domestic appliance with a self-retracting element or damper is possible at any time, for example, by changing the pushing element or press-fitting the self-retracting element or damper into a clear area of a pushing element. If the drive element is also fixed to an interchangeable component, then this can be changed. However, a drive element of this type can also be fixed from the front on the corresponding component. As an alternative, the drive element can also be embodied as a separate component, which is fixed for readjustment in a stationary component of the domestic appliance.

While in FIG. 8 the self-retracting element or the damper is arranged below the extraction rail 62, an arrangement is also possible above the extraction rail 62 for example in the side wall of the drawer. The drive element must then be arranged correspondingly on the inner side wall of the inner container.

An embodiment is shown in FIG. 10, in which only a first drive element 72 is arranged in the pushing element 70, while the self-retracting element 71 or buffer is arranged in a stationary area of the household appliance, in this case in an intermediate bottom 73. Alternatively the self-retracting element 71 or damper could also be arranged in a lid or part of the inner container. For the mounting of the self-retracting element or of the damping, a corresponding depression is again provided, in which the self-retracting element or the damping is recessed.

In this sense the self-retracting element or the damper is fixedly housed in a bottom, lid or inner container located below the push element 70. It is located in this direction in a notch in the rear area. The entire self-retracting element is recessed and is thus protected from damage.

Only a second driving element 74 leaves the self-retracting element or damper and can engage with the first driving element 72 in the pushing element 70.

The self-retracting element or the damping can be re-assembled by means of retaining hooks so that the self-retracting or damping element can be easily inserted and locked in its final position in the depression. Dismantling can then happen only from the customer service center with a tool.

The positioning of the self-retracting element or shock absorber can be carried out again to the left, to the right or in the center. The placement of the center offers the advantage that the introduction of force takes place in the center. The drawer rolls in a uniform and straight way, so that a tilting is prevented, especially in the case of full load. The technical realization of a self-retracting element requires the first trailing element in the self-retracting element. thrust, which engages in the self-retracting element, initiates the self-retracting element and absorbs tensile forces. The first drive element 72 is arranged in the push element embedded in it. By embedding this trapping element, damage can be avoided by depositing the drawer, for example, in the kitchen during extraction and cleaning.

A readjustment of an existing domestic appliance with this embodiment of the present invention can be carried out by changing a lid or shelf with a self-retracting element or damper of this type. Alternatively, a self-retracting or shock absorbing element can also be arranged in a housing of the inner container.

The drag element in the drawer can be provided mounted there or by a change of the pushing element. The pusher 72 in the pushing element engages again in the self-retracting element and absorbs tensile forces. Unlocks in this way during extraction. The pusher is arranged in this direction plugged into the thrust element to prevent damage.

By means of the recessed mounting of the self-retracting or damping element according to the present invention, an extremely compact and safe construction against damage is produced. In particular in this sense a cover can be provided, which covers the depression and the elements arranged therein. Therefore, damage can be ruled out if the self-retracting or damping element can not be reached by the user. However, a transmission of force from a moving element of the self-retracting element or damper along a certain thrust path towards the thrust element must be carried out in this direction. In this connection, for example, a rubber skirt can be provided along an oblong hole, through which a driver passes, which produces the force-pulling connection between the moving part of the self-retracting or shock-absorbing element and the element. of push.

Alternatively, the cover can also roll together along the necessary thrust path with moving element of the self-retracting or damping element. Advantageously, the cover is thus guided in a displaceable manner in the depression. Therefore, an oblong hole can be avoided and the depression encapsulated completely. The transmission of force is then carried out by means of a second drive element in the cover. In addition, the self-retracting element or damper is advantageously arranged in a depression of a mounting rail, which in turn is arranged in a depression of the internal container. When recessed in the mounting rail, which is again embedded in the internal container, the self-retracting element or shock absorber does not require any storage space.
