Description

 Household refrigerator

The invention relates to a household refrigerator with an interior to be cooled with a rear wall and two side inner walls, which can be closed with a door.

Refrigerators have pull-out trays or shelves for storing refrigerated goods. In order to meet the individual wishes of the user these are adjustable to different heights or can be arranged. Pull-out trays or shelves can be pulled out of the interior of the refrigerator for easier access to refrigerated goods.

DE 9314675 U1 shows a refrigerator whose shelves are extendable and adjustable in height. This takes place in that two vertical rails parallel to each other and to the opening side of the refrigerator door are arranged on the side walls of the refrigerator compartment, which are provided with latching recesses at intervals and in which latchable and releasable holding pieces are displaceably guided. The holding pieces are provided on their sides facing each other with guide pieces which engage in the shelves and thus allow Hohenverstellbarkeit along the rails. The shelves have grooves into which the guide pieces engage and extending along these grooves according to their length is possible.

Such an adjustment is very cumbersome in its handling, since on the one hand the extract is limited to the possible groove lengths and on the other hand, the Hohenverstellbarkeit on the side rails only with a certain effort and fingertip feeling is possible.

It is therefore an object of the invention to provide an adjustment system for storage plates and pull-out trays, which allows a simple adjustment of the position and overcomes the disadvantages of the prior art.

To solve this problem, the invention proposes a household refrigerator according to claim 1. The domestic refrigerator according to the invention has an interior to be cooled with a rear wall and two side inner walls, which can be closed with a door. At least two cams are provided on each side wall. These are arranged substantially horizontally relative to one another and communicate with at least one corresponding lateral holding element for a plate or a container. These engage in a corresponding guide of the lateral holding element, which is aligned horizontally and / or vertically and over which the plate or the container is arranged horizontally and / or vertically movable.

The cams are at least substantially horizontal to each other, that is, that they are located approximately at the same height. Thus, these can engage in the guide of the lateral support member and hold the plate or the container in the desired position, wherein the plate or the container via the cams is horizontally and / or vertically movable. A plate or a container may be, for example, a shelf made of plastic, glass or a grid, as well as an extract tray, which may have different depths. The lateral holding element may be part of a plate or a container. It may also be part of a frame or a lateral rail which is arranged on the plate or the container. The guidance of the lateral holding element is determined by its shape and can be, for example, a groove or a rail. Due to this simple structure, the cooling interior cams, which are arranged approximately at the same height, at defined locations or at defined intervals and only by the interaction with the corresponding guide height adjustment or an excerpt of the plate or container is possible , By "cam" is meant a projection which is preferably not equipped with a guide wheel or the like and, for B. has an approximately cylindrical shape. This simple structure is comfortable and inexpensive to manufacture. The susceptibility to error of this structure is also low, since here are few elements related to each other. Preferably, at least one wall element which has a substantially horizontal orientation is arranged for each side inner wall. The wall element has the at least two cams, which engage in a corresponding guidance of the lateral Chen holding element engage. About this horizontal arrangement, the plate or the container is arranged horizontally and / or vertically movable.

The wall element is oriented horizontally, that is, it runs along a plane parallel to the bottom surface. The cams are therefore arranged one behind the other in approximately the same height. Thus, it is possible to arrange a plurality of wall elements at different heights, which can each accommodate a plate or a container.

Preferably, the wall element is a molded part which can be inserted into the side inner wall. Thus, it is easy to manufacture and easy to handle. In addition, the attachment is reliable and robust.

According to a special embodiment, the cams are formed from the respective side inner wall. Preferably, the cams are already formed in the manufacturing process of the so-called "inner liner" of the household refrigerator by deep drawing from the side inner walls. This allows a cost effective and very simple method of production.

According to a preferred embodiment, on each side inner wall, in each case three cams, which are arranged substantially horizontally to one another, are provided. This means that three cams can be provided at approximately the same height. However, several sets of 2 or 3 cams, which are each arranged at a different height can be provided on a side inner wall. Three cams allow a very reliable arrangement of a plate or a container, wherein the extract can follow beyond the rearmost cam, since the two front cams can absorb the forces on the extended plate or the extended container satisfactorily. The cams can be formed both from the side inner wall, as well as be assigned to the wall element.

Preferably, the guide in the lateral holding element on at least two substantially vertical grooves, which are each guided along at least one cam for height adjustment of the plate or container. The vertical guide thus takes place via grooves which are arranged in the holding element. Thus, it is possible for a user, the plate or the container by simply raising or lowering the plate or the To adjust container in the interior space of the household appliance. It is not necessary to operate additional control elements or to lift the plate or the container out of the cams.

Preferably, at least one substantially horizontal groove branches off from the at least one substantially vertical groove, which is arranged on the cam in order to serve as a stop for the plate or container in one of a plurality of vertical positions. Thus, it is possible to hold a plate or a container in a vertical position, it being conceivable here that the groove has two or more horizontal recesses and thus the lateral holding element has a plurality of setting positions to the plate or the container in different To place heights. Thus, the height adjustment of the plate or the container is very easy to handle implemented with simple means and designed very variable.

Preferably, the cam lying closest to the rear wall has a smaller cross-sectional area or a smaller diameter than the at least one further cam. This offers the possibility that the recesses or the grooves on the lateral holding element have individual regions for each cam and thus prevents the container or the plate from being arranged in a wrong position on the cam. In addition, it is possible to assign different functions to the recesses or grooves which are adapted to the different sizes of the cams.

Particularly preferably, the horizontal movement of the plate or the container from the interior of the household refrigerating appliance along the cams via at least one substantially horizontal groove. Such an extract is very simple, thus very easy to manufacture and in its handling. A horizontal groove means that the cam is guided in a recess which has at least one closed upper edge.

Preferably, the at least one substantially horizontal groove tapers in a rear region, ie the region which is closest to the rear wall of the refrigeration device. The taper prevents slipping of the plate or the container of all cams and thus serves as a stop for at least one cam. According to one embodiment, the rearmost, smaller cam can be guided by the taper of the groove and the taper serve as a stop for the following cam. In this case, an extract is made possible, which goes beyond the rearmost cam and thus takes place far out of the interior of the household refrigerator. This is particularly advantageous for the user, since the plate or the container is exposed and the refrigerated goods are easily accessible.

Advantageously, the at least one substantially horizontal groove on the bottom side openings, which allows insertion into the groove by placing the plate or container on the cam. This is a special embodiment, for example, if the groove is tapered in a rear area and thus a sliding from the front is not possible, so a placement from above on the cam is necessary. However, this can also be done independently of a taper, since a placement of the plate or the container from the top of the cam for a user is advantageous because it is much easier than a push from the front.

According to another embodiment, the lateral retaining element both at least one substantially horizontal and at least one substantially vertical groove for height adjustment and the extension of the plate or the container. Such a combination of both processes creates a very variable adjustment system, which is easy to handle, since the user only needs to grasp the plate or the container from the front and lift or pull in the appropriate position. In addition, this adjustment is less susceptible to interference, since it has very few items.

For example, the lateral holding element of the plate or of the container is raised at least in its side regions with respect to a shelf of the plate or of the container. It is thus conceivable that a plate or a container has a lateral holding element, which protrudes far beyond the edge of the plate or the container due to its adjustment, wherein the lateral holding member may extend both upwards and downwards. However, it is also possible that the plate or the container has a frame which extends over the refrigerator interior door or the

Rear wall facing side extends and thus forms a shell or at least a border. In the following, various embodiments of the invention will be described with reference to FIGS. 1 to 5:

Figure 1 shows a schematic perspective view of an embodiment of a household refrigerator 1, which has a closable by a door 12 interior 13. On the inner side walls 1 1 shelves 4 are placed. This is done here via cams 2, 2 ', which are fastened to a wall element 3, wherein the wall element 3 is placed on the side inner wall 1 1. This wall element 3 has three cams 2, 2 '. The cam 2 'located closest to the rear wall 14 is significantly smaller in diameter and in particular in its vertical extent than the two further cams 2. A further storage plate 4 can be arranged on these cams 2, 2'.

Figure 2 shows a perspective schematic view of an embodiment of a storage plate 4 with lateral support members 5 and two wall elements 3 with cams 2, 2 ', which should engage in the lateral support member 5. The lateral support members 5 are z. B. plastic strips which are molded laterally on the glass shelf 4. The wall- Element 3 each has three cams 2, wherein the rearmost cam 2 'has a smaller cross-sectional area than the other two cams 2. The wall element 3 also has two male elements 15 which are for inserting the wall element 3 in a side inner wall 1 not shown. 1 serve the household refrigerator 1. The cams 2, 2 'engage in the groove 6 of the lateral holding element 5. In the installed state, the tray can be placed from above on the cams 2, 2'. Here, the cams 2, 2 'are introduced via bottom-side openings 8 in the groove 6. About the groove 6, the tray 4 can be pulled out of the cooling interior. In this case, the lateral holding element 5 is moved with the tray 4 along the cam 2. In the rear region of the lateral holding element 5, the groove tapers 6. Here, the groove 6 a rejuvenation 7 on. By this taper 7 even the smaller cam 2 'but not the next lying cam 2. So the tray 4 can be extended so far that the groove 6 no longer engages in the small cam 2' and the closest cam 2 abuts the taper 7 , Since the wall element 3 has a total of three cams 2, 2 ', the tray 4 also holds securely on the two front cams. It is also conceivable to arrange 4 or 5 cams and thereby provide several small cams, which can run through a taper to ensure a more stable guidance in very deep refrigerators or heavy plates.

The lateral holding element 5 has a groove 6 with a taper 7, in which case the cams 2, 2 'are connected to the groove stand. The plate 4 was placed here on the openings 8 on the cam 2 and extended a piece. Now the rearmost cam 2 'in the taper 7. The plate 4 can still be extended until the nearest cam 2 has arrived at the taper 7 and strikes there because of its size. The lateral retaining element can thus be extended beyond the smaller cam 2 '.

FIG. 4 shows a schematic perspective view of another exemplary embodiment of a storage tray 4 with a lateral holding element 5 which is formed here as a frame. The storage plate 4 is height adjustable here in two positions. This is done via a vertical groove 9 in the lateral holding element 5. The cams 2, 2 'engage in the vertical groove 9. The positions at different heights can be determined by stops 10. In a fixed position, the cams 2, 2 'engage in one of the two stops. ge 10 of the vertical groove 9. It is conceivable to provide even more stops 10 for more height settings between these two height settings.

FIG. 5 schematically shows a side view of a lateral holding element 5 according to a specific embodiment. Based on this lateral support member 5, an adjustment can be made both in the vertical direction and in the horizontal direction. The horizontal grooves 6 taper in a rear region and each have a taper 7. The lower horizontal groove 6 has openings 8, through which a storage plate or container on which this lateral holding element 5 is arranged, on the cam 2, 2 'can be placed. As shown in the previous exemplary embodiments, a horizontal groove 6 can be pushed over the smaller cam 2 ', wherein the taper 7 forms a stop for the nearest cam 2. In this embodiment, in such an extended position, a height adjustment via the vertical grooves 9 take place. Thus, a plate 4 or a container can be extended at two different heights via such a lateral holding element 5. It is conceivable to provide a similar lateral retaining element 5, which allows a plurality of height settings, in each of which the plate 4 can be extended. In addition, the invention is not limited to that the height adjustment must be made in the extended position.
