Description

Refrigeration device, in particular stationary refrigeration device

The invention relates to a refrigeration device, in particular stationary refrigeration device, according to the preamble of claim 1, a method for the production of refrigerators

Different variants according to claim 13 and a front frame strip for a refrigeration device according to claim 14.

Refrigerators can be integrated as built-in appliances in the kitchen furniture front. In addition, the refrigerators can alternatively be designed as freestanding floor refrigerators. In such a stationary refrigeration device, not only the front side, but also the lateral device outer walls are visible. These can be made, for example, from a stainless steel sheet, with a device front-side fold of these stainless steel sheets can move a feed opening of the refrigerator and also as a

magnetic partner interacts with the magnetic seal of the appliance door.

Alternatively to the use of such stainless steel sheets, the device outer walls of stationary refrigerators can also be made of plastic. However, since the magnetic seal of the door needs a magnetic partner, is a mere replacement of the

Stainless steel sheets with the plastic board not possible. Likewise, it is particularly important in stationary refrigerators of importance to ensure a visually flawless transition between the device outer wall and the inner wall delimiting the refrigerator space, without being visually disadvantageous at the transition joints can be seen.

The object of the invention is to provide a refrigeration device, a method for producing refrigerators of different variants as well as an insertable in the refrigerator front bezel, the use of non-ferromagnetic

Device exterior walls allowed.

The object of the invention is characterized by the features of claim 1, of

Claim 13 or of claim 14 solved. Preferred embodiments of the invention are disclosed in the subclaims. According to the invention, a cavity filled with thermal insulating foam is defined by a cooling wall bounding the inner wall and a device outer wall in a refrigeration device. The inner wall is connected via a front frame strip with the device outer wall in conjunction. In addition, the front frame strip can interact as a magnetic partner with a magnetic door seal of the appliance door. According to the

characterizing part of this front frame strip is formed as a separate component having a first connection profile for connection to the inner wall and a second connection profile for connection to the device outer wall.

The front frame, the inner wall and the device outer wall can therefore be made of different materials, each on the

Funktionserfordemissem is optimized. In the execution of the device outer wall as a plastic board, therefore, the front frame strip can be made by a ferromagnetic material, making it safe to work together as a magnetic partner with the magnetic door seal the door. The inner wall, however, can also be made in known manner from plastic material.

Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the

Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer or a wine fridge.

For easy installation without additional fasteners, the two connection profiles of the front frame strip can be designed as plug-in receptacles. In this plug-in receptacles can then associated Steckprofile the inner walls and

Device outer walls are plugged in a direction of insertion. The device outer wall forms, as mentioned above, together with the inner wall a hollow body which is filled in a subsequent Schäumungsvorgang with a Wärmeisolierschaum.

It is preferred if the front frame strip is designed as a metal profile part, which thus also acts as a magnetic partner with the magnetic door seal of the appliance door can interact. The front frame strip can be favorable manufacturing technology, a sheet metal part, the contour of which is produced in a forming process.

The above-mentioned plug-in profiles can be angled in the device side direction facing each other in each case by the inner wall and by the device outer wall by about 90 °. The plug-in profiles may extend substantially over the entire height of the device. It is between the device outer wall and the molded

Plug profile formed bending edge at the same time also a front outer edge of the device, which can be aligned approximately flush with the door outer edge. Especially with free-standing floor refrigerators a dimensionally stable device design is of great importance. Thus, by suitable training of the connection points between the

Device outer wall, the front frame strip and the inner wall, the device stiffness are positively influenced. Against this background, the plug-in profiles of the inner wall and the device outer wall may preferably overlap in the device side direction and be aligned with each other. Accordingly, the

Plug receptacles of the front frame strip in the device side direction be open to each other in opposite directions. It is preferred if the male profile of

Device outer wall in a, in the device side facing outward

Plug-in receptacle is used. In contrast, the male profile of the inner wall in a, in the device side direction inwardly facing plug-in receptacle of

Front frame bar are used.

This results in a nested in the Bautiefenrichtung arrangement of the two plug-in profiles. For reasons of device rigidity, it is preferred if the

Plug profile of the device outer wall in a front plug-in receptacle of

Front frame strip can be used while the plug-in tab of the inner wall can be inserted into a plug-in receptacle arranged behind it.

In particular, in freestanding state refrigerators can also be a joint-free overall appearance of advantage. The transition joints formed between the front frame strip and the associated device outer walls and inner walls can therefore preferably be positioned on the front of the device, which can be covered by the appliance door. As already mentioned above, the front frame strip can be a bent sheet metal part. The

Front frame strip may have a central partition, on both sides of the plug receptacles are formed. For shaping the plug-in receptacles, the

Partition be extended on opposite sides in each case with legs, which are bent opposite to each other and each define a plug-in receptacle together with the partition. The legs of the plug-in receptacle can preferably be made elastically bendable, whereby the legs can be deformed elastically adjustable during insertion of the plug-in profiles under construction of a restoring force.

To further increase device rigidity, the bezel bar may also have contact surfaces which are in abutment with the inner corner area between the

Device outer wall and its angled Steckprofil. In this way, the front corner areas which are relevant in terms of dimensional stability can be at least partially embodied in a double-wall structure. In an embodiment set out above, therefore, the male profile of

Device outer wall encompassing leg device front side exposed and cooperate as a magnetic partner for a magnetic door seal the door.

The use of the front frame strip according to the invention is particularly in the

Large-scale production of refrigeration units of advantage, in which different

Device variants are manufactured. Thus, in a first device variant, the

Device outer wall have an integrally formed thereon, bevelled end piece with connection profile, as it is easy to produce in sheet metal blanks by drawing processes. This allows the device outer wall with the molded on it

Connection profile simply be connected to the refrigerator wall bounding the inner wall.

In a second device variant, however, the tail can be designed as a separate component, that is, as the front frame strip according to the invention, which additionally has the second connection profile. The front frame strip is therefore not only connected to the inner wall, but also with the housing outer wall releasably connectable. Hereinafter, three embodiments of the invention will be described with reference to the accompanying drawings.
