Description

Bei Kühlmöbeln und dergleichen sind Zwischenwände vorgesehen, die aus Blech gefertigt sind. So ist beispielsweise auf der Innenseite des Kühlmöbels als Abgrenzung des Kaltluftstromes gegen den Warenraum eine Zwischenwand vorgesehen, die in einem Abstand von ca. 3 bis 5cm vor der eigentlichen Möbelrückwand angeordnet ist. Der dadurch gebildete Kanal über die gesamte Rückseite und die Decke des Möbels dient der Leitung der Kaltluft, die im Unterteil des Möbels erzeugt und mittels Ventilatoren in den Kopfteil des Möbels geblasen wird. An der Vorderkante dieses Kopfteils strömt die Kaltluft heraus in den Warenraum des Kühlmöbels. Die nach unten sinkende Kaltluft wird an der Vorderkante des Möbelunterteils abgesaugt, dem Kühlaggregat zugeführt und mittels eines Gebläses aus diesem Kühlaggregat abgeführt und in den Kanal zwischen Kühlmöbelrückwand und Zwischenwand nach oben geblasen, so dass der Kreislauf geschlossen ist. Diese sog. Luftleitbleche sind meist noch mit Durchbrechungen versehen, die die Kaltluftverteilung im Kühlmöbel unterstützen. Diese Durchbrechungen sind von Möbeltyp zu Möbeltyp unterschiedlich und werden in der Praxis erprobt und danach festgelegt.In cooling furniture and the like intermediate walls are provided, which are made of sheet metal. For example, an intermediate wall is provided on the inside of the cabinet as a delimitation of the cold air flow against the goods space, which is arranged at a distance of about 3 to 5cm in front of the actual furniture back wall. The channel thus formed over the entire back and the ceiling of the furniture is used to direct the cold air, which is generated in the lower part of the furniture and blown by fans in the headboard of the furniture. At the front edge of this head part, the cold air flows out into the goods compartment of the refrigerator. The descending cold air is sucked off at the front edge of the furniture base, fed to the cooling unit and discharged by means of a blower from this cooling unit and blown up into the channel between the cooling furniture rear wall and intermediate wall, so that the circuit is closed. These so-called. Air baffles are usually still provided with openings that support the cold air distribution in the refrigerator. These openings are different from furniture type to furniture type and are tested in practice and then determined.

Die Herstellung dieser pulverbeschichteten oder auch nass lackierten Stahlblechzwischenwände ist ziemlich aufwendig, da sie korrosionsfest sein müssen. Zusätzlich werden teure Stanzwerkzeuge benötigt, um die verschiedenen Durchbrechungen herzustellen.The preparation of these powder-coated or wet-painted steel sheet partitions is quite expensive, since they must be resistant to corrosion. In addition, expensive punching tools are needed to make the various apertures.

Aufgabe der Erfindung ist es, Zwischenwände, insbesondere Luftleitbleche für Kühlmöbel zu schaffen, die in der Herstellung einfach und kostengünstig sind, die aber dennoch korrosionsfest sind und den gehobenen Anforderungen bei solchen Kühlmöbeln gerecht werden. Diese Aufgabe wird gemäß den Merkmalen des Anspruch 1 gelöst.The object of the invention is to provide intermediate walls, in particular air baffles for refrigeration cabinets, which are simple and inexpensive to manufacture, but which are non-corrosive and the higher requirements meet with such refrigeration furniture. This object is achieved according to the features of claim 1.

Dadurch, dass das Kühlmöbel mit einer Zwischenwand ausgestattet ist, die nicht tragend ist, lediglich aus einem Rahmen besteht, der mit einem textilen Stoff, einer Folie oder einem Vlies bespannt ist, wird die Herstellung wesentlich vereinfacht und ist kostengünstig. Außerdem wird das Gewicht der Zwischenwand auf etwa 1/5 reduziert, so dass das Kühlmöbel wesentlich leichter handhabbar ist. Durchbrechungen sind in die Bespannung auf einfache Weise einzubringen und erfordern keine teuren Stanzwerkzeuge. Ferner wird erreicht, dass die Zwischenwand korrosionsfrei ist und sich leicht reinigen lässt.The fact that the refrigerator is equipped with an intermediate wall, which is not load-bearing, consists only of a frame which is covered with a textile fabric, a film or a nonwoven, the production is much easier and is inexpensive. In addition, the weight of the partition is reduced to about 1/5, so that the refrigeration cabinet is much easier to handle. Breakthroughs are easy to bring into the fabric and do not require expensive punching tools. Furthermore, it is achieved that the partition is corrosion-free and can be easily cleaned.

Ist für die Zwischenwand ein separater, in das Kühlmöbel einsetzbarer Rahmen vorgesehen, so kann die Zwischenwand leicht ausgewechselt werden. Es können aber auch Streben des Kühlmöbelgestells als Rahmen dienen, an denen die Bespannung unmittelbar befestigt ist. Vorzugsweise besteht der Rahmen aus Leichtmetallprofilen und ist dadurch korrosionsbeständig. Verwendet man für die Bespannung einen textilen Stoff, so können die Durchbrechungen bereits bei der Herstellung eingearbeitet werden. Durch die Variation der Dichte des textilen Stoffes kann eine bestimmte gewünschte Luftdurchlässigkeit erzeugt werden. Es erübrigen sich Stanzwerkzeuge überhaupt.If a separate frame which can be inserted into the refrigeration appliance is provided for the intermediate wall, the intermediate wall can be easily replaced. But it can also serve as a frame struts of Kühlstandsgestells where the fabric is attached directly. Preferably, the frame is made of light metal profiles and is therefore corrosion resistant. If a textile material is used for the covering, the openings can already be incorporated during production. By varying the density of the textile fabric, a certain desired air permeability can be generated. There are no need for punching tools at all.

Durch die EP 0 340 743 ist es bekannt, im Transportladeraum eines LKW's unter die Kaltluftaustrittsdüsen eine gitterförmige Decke anzuordnen, deren Gitterfelder mit einem textilen porösen Gewebe bespannt sind, welches von der gesamten Kühlluft durchströmt werden muss und so für die aus den Austrittsdüsen austretende Kaltluft eine gute Verteilung über die gesamte Deckenfläche in den Ladenraum bewirken soll.By the EP 0 340 743 It is known to arrange a grid-like ceiling in the cargo compartment of a truck under the cold air outlet nozzles whose grids are covered with a textile porous fabric, which must be traversed by the entire cooling air and so for the emerging from the outlet nozzles cold air a good distribution over the entire ceiling surface to effect in the store room.

Die US-A-4 402 192 beschreibt ein Kühlmöbel, in welchem für die Zirkulation über die ausgestellten Waren die Luftströmung durch einen Kanal geleitet wird. Da durch die Rückwandung eine Beschickung der Warenfächer und auch des Warenraumes ermöglicht werden soll, ist diese Rückwand aus flexiblen Bälgen ziehharmonikaartig ausgebildet, die gleichzeitig Tür- und Luftkanal bilden.The US-A-4 402 192 describes a refrigerated cabinet in which the air flow is passed through a channel for the circulation of the issued goods. Since a loading of the goods compartments and the goods space should be made possible by the rear wall, this rear wall is made of flexible bellows accordion-like, which simultaneously form the door and air duct.

Aus der US-PS 3.584.467 ist ein Kühlmöbel bekannt mit einem von der Frontseite zugänglichen Warenraum, der in horizontale Fächer unterteilt ist und auf seiner Rückseite von einem Luftführungskanal begrenzt wird, wobei der Luftführungskanal warenraumseitig durch eine Zwischenwand und durch die Rückwand des Kühlmöbels gebildet wird.From the U.S. Patent 3,584,467 a refrigeration unit is known with an accessible from the front goods compartment, which is divided into horizontal compartments and is bounded on its rear side by an air duct, wherein the air duct on the goods side is formed by an intermediate wall and through the rear wall of the cabinet.

Das Kühlmöbel 1 besteht üblicherweise aus einem Gehäuse 11, das eine Rückwand 3 aufweist. In dem Gehäuse 11 sind einzelne Regalfächer durch Zwischenböden 4 angeordnet. Im unteren Teil des Kühlmöbels ist das Kühlaggregat 5 mit Ventilatoren 6 ange ordnet. Die Regalfächer mit den Regalböden 4 sind durch eine Zwischenwand 2 an ihre Rückseite begrenzt. Zwischen dieser Zwischenwand und der Rückwand 3 des Kühlmöbels 1 wird dadurch ein Luftkanal 12 gebildet. In dem horizontalen Teil des Luftkanals 12 wird dieser durch eine horizontal angeordnete Zwischenwand 21 gegen das oberste Regalfach abgegrenzt.The refrigeration unit 1 usually consists of a housing 11, which has a rear wall 3. In the housing 11 individual shelves are arranged by shelves 4. In the lower part of the cabinet, the cooling unit 5 with fans 6 is arranged. The shelves with the shelves 4 are bounded by an intermediate wall 2 at its rear. An air channel 12 is thereby formed between this intermediate wall and the rear wall 3 of the refrigerated cabinet 1. In the horizontal part of the air channel 12 this is delimited by a horizontally arranged intermediate wall 21 against the top shelf.

Durch die Ventilatoren 6 wird ein Luftstrom erzeugt, der die Luft aus dem Kühlraum ansaugt und durch das Kühlaggregat 5 drückt, in welchem die Luft abgekühlt und in dem vertikalen Teil des Kanales 12 nach oben gedrückt wird. Über den horizontalen Teil des Kanales 12 gelangt die Luft im Kopfteil des Kühlmöbels an die Frontseite und fällt dort nach unten, wobei sie am Unterteil des Kühlmöbels durch die Ventilatoren 6 wieder abgesaugt und dem Kühlaggregat 5 zugeführt wird.By the fans 6, an air flow is generated, which sucks the air from the refrigerator and presses through the cooling unit 5, in which the air is cooled and pressed in the vertical part of the channel 12 upwards. Over the horizontal part of the channel 12, the air in the head part of the cabinet reaches the front and falls down there, being sucked out again at the bottom of the cabinet by the fans 6 and the cooling unit 5 is supplied.

Bisher war es üblich, diese Zwischenwand 2 tragfähig aus Blech herzustellen und mit Durchbrechungen zu versehen. Auch im Kopfteil wurde die Zwischenwand 21 aus tragfähigem, stabilem Blech hergestellt. Dadurch wurde das Gewicht des Kühlmöbels erheblich vergrößert und Transporte und Umstellungen des Kühlmöbels im Verkaufsraum erschwert. Durch die Ansammlung von Kondenswasser sind diese Zwischenwände 2, 21 korrosionsgefährdet und müssen deshalb mit einer korrosionsfesten Beschichtung versehen werden, beispielsweise durch Pulverbeschichtung, Einbrennlackierung und dergleichen. Hierfür sind mehrere Arbeitsgänge erforderlich, die die Herstellung derartiger Zwischenwände erheblich verteuern.So far, it has been customary to produce this intermediate wall 2 load-bearing from sheet metal and to provide with openings. Also in the headboard, the intermediate wall 21 was made of stable, stable sheet metal. As a result, the weight of the cabinet has been significantly increased and difficult transport and conversion of the cabinet in the sales area. Through the collection of condensation, these partitions 2, 21 are at risk of corrosion and must therefore be provided with a corrosion-resistant coating, for example by powder coating, baking enamel and the like. For this purpose, several operations are required, which significantly increase the production of such partitions.

Figur 2 zeigt den Aufbau einer erfindungsgemäßen Zwischenwand, die aus einem Rahmen 7 besteht, der in den Ecken Versteifungen 71 aufweist und mit einer Bespannung 22 versehen ist. Ein solcher Rahmen 7 lässt sich sehr günstig aus Profilmaterial her stellen, wobei sich besonders Aluminiumprofile eignen, da sie leicht und korrosionsbeständig sind. Die Bespannung 22 wird durch Umschlagen und Klammern an dem Rahmen 7 befestigt. Zusätzlich kann auch eine Verklebung erfolgen. Ohne Verklebung lässt sich die Bespannung zur Reinigung leicht entfernen und wie ein normaler Stoff in einer Waschmaschine waschen. FIG. 2 shows the structure of an intermediate wall according to the invention, which consists of a frame 7, which has stiffeners 71 in the corners and is provided with a covering 22. Such a frame 7 can be made very favorable from profile material ago, with aluminum profiles are particularly suitable because they are light and resistant to corrosion. The fabric 22 is attached by folding and staples to the frame 7. In addition, a bond can be made. Without gluing the fabric can be easily removed for cleaning and washed like a normal fabric in a washing machine.

Figur 3 zeigt eine Bespannung 23, die aus einer PVC-Folie her gestellt ist. Da diese luftdicht ist, werden Durchbrechungen 24 angeordnet, um einen Luftaustausch zum Kühlraum zuzulassen. Je nach Gestaltung des Kühlraumes werden diese Durchbrechungen angeordnet und auch in ihrer Größe bestimmt. Für die erforderliche Kühlströmung kann es zweckmäßig sein, nur im oberen Teil Durchbrechungen anzuordnen. Bei der Unterteilung des Kühlraumes in Fächer durch Zwischenböden 4 ist es zweckmäßig, jeweils für das betreffende Kühlfach die Durchbrechungen in Größe und Anordnung zu bestimmen, gegebenenfalls auch hier wieder nur im oberen Teil des Kühlfaches Durchbrechungen bzw. eine bestimmte Luftdurchlässigkeit vorzusehen. FIG. 3 shows a fabric 23, which is made of a PVC film forth. Since this is airtight, openings 24 are arranged to allow an exchange of air to the refrigerator. Depending on the design of the refrigerator, these openings are arranged and also determined in size. For the required cooling flow, it may be appropriate to arrange openings only in the upper part. When subdividing the cooling compartment into compartments by means of intermediate floors 4, it is expedient to determine the openings in size and arrangement for the relevant compartment, if necessary again to provide openings or a specific air permeability only in the upper part of the compartment.

Bei Verwendung einer textilen Bespannung können derartige Durchbrechungen in den Stoff bei seiner Herstellung eingearbeitet werden, so dass weitere Arbeitsgänge, wie das Einstanzen von Durchbrechungen nicht erforderlich sind. Der Stoff wird zweckmäßig aus synthetischen Fäden hergestellt und durch entsprechende Bindungsstrukturen eine bestimmte erforderliche Luftdurchlässigkeit erzeugt. Selbstverständlich ist es möglich, auch hier die Bindungsstrukturen entsprechend der Aufteilung des Kühlraumes oder den Strömungsverhältnissen so anzuordnen, dass die Luftdurchlässigkeit der Bespannung beispielsweise im oberen Teil größer ist als im unteren Teil. Es kann sowohl eine Maschenware, als auch ein Webstoff für die Bespannung verwendet werden. Durch Variation der Dichte der Bindung kann auch ohne besondere Durchbrechungsstrukturen die Luftdurchlässigkeit des Stoffes so beeinflusst werden, dass der erforderliche Luftaustausch zum Kühlfach gegeben ist. Dies kann durch die Auswahl des Fadenmaterials, aber auch durch die Faden- bzw. Maschendichte erreicht werden. Hier zeigen sich die besonderen Vorteile einer textilen Bespannung, da die Herstellung eines textilen Stoffes sehr flexibel ist und ohne großen Aufwand dieser sowohl den gewünschten Strömungsverhältnissen im Kühlmöbel als auch in der optischen Erscheinung angepasst werden kann.When using a textile covering such breakthroughs can be incorporated into the fabric in its manufacture, so that further operations, such as the punching of openings are not required. The fabric is suitably made of synthetic threads and by appropriate bonding structures a certain required air permeability generated. Of course, it is also possible to arrange the binding structures according to the division of the cooling space or the flow conditions so that the air permeability of the fabric, for example in the upper part is greater than in the lower part. It can be used both a knitted fabric, as well as a woven fabric for the covering. By varying the density of the bond, the air permeability of the substance can be influenced even without special opening structures so that the required air exchange is given to the cooling compartment. This can be achieved by selecting the thread material, but also by the thread or stitch density. This shows the particular advantages of a textile covering, since the production of a textile material is very flexible and can be adapted without much effort this both the desired flow conditions in the refrigerator and in the visual appearance.

Zur Befestigung der Bespannung 22 kann diese an den Rändern mit entsprechenden Verstärkungen für die Befestigung versehen sein. Wird der Rahmen, wie in Figur 4 dargestellt, durch ein längsgeteiltes Profil gebildet, so kann die Bespannung zwischen den beiden Profilteilen eingespannt und auf diese Weise besonders gleichmäßig und dennoch lösbar befestigt werden. Nach Figur 4 besteht der Rahmen 7 aus einem Profil 70, das mit einem Rahmenteilprofil 70' verschraubt ist. Dazwischen wird die Bespannung 22 oder 23 durch Klemmung festgehalten. Eine andere Art zeigt Figur 5, bei welcher eine Klemmleiste 72 die Bespannung 22, 23 in das Profil 7 einzieht und klemmt. Mit dieser Ausführung ist ein Spannen der Bespannung 22, 23 leichter möglich. Im Falle der Beschädigung lässt sich die Bespannung leicht auswechseln.To attach the fabric 22 may be provided at the edges with corresponding reinforcements for attachment. Will the frame, as in FIG. 4 represented formed by a longitudinally split profile, the fabric can be clamped between the two profile parts and secured in this way particularly evenly and yet releasably. To FIG. 4 the frame 7 consists of a profile 70 which is bolted to a frame part profile 70 '. In between, the covering 22 or 23 is held in place by clamping. Another way shows FIG. 5 in which a clamping strip 72, the clothing 22, 23 moves into the profile 7 and clamped. With this embodiment, a tensioning of the fabric 22, 23 is easier. In case of damage, the covering can be easily replaced.

Bei den bisher beschriebenen Zwischenwände wurde ein extra für die Zwischenwand hergestellter Rahmen verwendet, auf dem eine Bespannung angebracht wurde. Die so hergestellte Zwischenwand ist in das Kühlmöbel einsetzbar und auch leicht wieder herausnehmbar. In Figur 6 ist eine Zwischenwand 22 gezeigt mit Rahmenprofilen 7, wobei die Zwischenwand 22 zwischen den Tragprofilen 74 des Kühlmöbels jeweils eingesetzt und an diesen befestigt ist. Als Rückwand dient bei diesem Kühlmöbel eine Isolation 31, die an den Tragprofilen 74 befestigt ist, so dass ein Luftkanal 12 in der Breite der Tragprofile 74 entsteht. In diesem Luftkanal 12 steigt jeweils die Kühlluft, wie oben bereits beschrieben, durch die Ventilatorwirkung nach oben in den Kopf des Kühlmöbels.In the partition walls described so far, an extra frame produced for the intermediate wall was used, on which a fabric was attached. The intermediate wall thus produced can be used in the refrigeration units and also easily removed again. In FIG. 6 is a curtain wall 22 shown with frame profiles 7, wherein the intermediate wall 22 is inserted between the support profiles 74 of the cabinet and each attached thereto. As a rear wall is used in this cooling furniture insulation 31 which is fixed to the support profiles 74, so that an air duct 12 in the width of the support profiles 74 is formed. In this air duct 12, the cooling air rises, as already described above, by the fan effect upwards into the head of the refrigerated cabinet.

Die Anordnung in Figur 7 hat den Vorteil, dass durch die Bespannung eine durchgehende Rückwand in den Regalfächern gebildet wird, so dass die Tragprofile 74 in ihrer Farbe nicht auf die Bespannung abgestimmt werden müssen, um eine durchgehend gleichmäßige Rückwand in den Regalfächern zu erreichen. Die Rahmen 7 der Zwischenwände 22 stoßen jeweils aneinander und sind an einem Tragprofil 74 jeweils befestigt. Diese Anordnung hat des weiteren den Vorteil, dass der Luftkanal 12 durch den größeren Abstand der Rückwand 22 von der Isolation 31 einen etwas größeren Querschnitt hat.The arrangement in FIG. 7 has the advantage that is formed by the covering a continuous rear wall in the shelves, so that the support profiles 74 in their color need not be matched to the fabric to achieve a consistently uniform back wall in the shelves. The frame 7 of the intermediate walls 22 abut one another and are each attached to a support profile 74. This arrangement also has the advantage that the air duct 12 has a slightly larger cross section due to the greater distance between the rear wall 22 and the insulation 31.

In Figur 8 ist auf einen gesonderten Rahmen für die Zwischen wand ganz verzichtet worden. Die Tragprofile 75 weisen jeweils eine Vertiefung 76 auf, in die mit einer Klemmleiste 73 die Bespannung eingezogen wird. Damit werden vertikale Rahmenprofile erspart. Die Zwischenwand ist sehr stabil.In FIG. 8 has been dispensed with a separate framework for the intermediate wall. The support profiles 75 each have a recess 76 into which the fabric is drawn with a clamping strip 73. This avoids vertical frame profiles. The partition is very stable.

Vorstehend ist die Zwischenwand 22,21 als Luftleitblech für die Kaltluft aus dem Kühlaggregat in den Kopf des Kühlmöbels beschrieben. Grundsätzlich können jedoch alle nichttragenden Zwischenwände in einem Kühlmöbel in dieser Weise hergestellt werden, wodurch das Kühlmöbel äußerst leicht und in seiner Herstellung verbilligt wird. Außerdem lassen sich diese Zwischenwände im Sichtbereich der Fächer in einfacher Weise gestalten und für Werbungszwecke verwenden. Als Bespannung können Stoffe oder Folien in den verschiedensten Farben verwendet werden.Above, the intermediate wall 22,21 is described as a baffle for the cold air from the cooling unit in the head of the refrigerator. In principle, however, all non-supporting partitions can be made in a refrigerated cabinet in this way, whereby the refrigeration cabinet is extremely easy and cheaper to manufacture. In addition, these partitions can be designed in the field of view of the subjects in a simple manner and use for advertising purposes. As a covering fabrics or films can be used in a variety of colors.
