Description

Kältegerätekorpus mit Luftkanal Refrigeration appliance body with air duct
Die vorliegende Erfindung betrifft einen Korpus für ein Kältegerät. Ein solcher Korpus ist herkömmlicherweise aufgebaut aus einem aus Kunststoff-Flachmaterial tiefgezogenen Innenbehälter, einer Außenhaut aus Blech- oder Kunststoffplatten, und isolierendem Schaummaterial, das einem Zwischenraum zwischen dem Innenbehälter und der Außenhaut ausfüllt.The present invention relates to a body for a refrigeration device. Such a body is conventionally constructed of a molded from plastic sheet material inner container, an outer skin of sheet metal or plastic plates, and insulating foam material, which fills a gap between the inner container and the outer skin.
Bei den so genannten No-Frost-Kältegeräten ist ein Verdampfer in einer von dem Innenraum abgetrennten Kammer untergebracht, und der Innenraum wird gekühlt durch Umwälzen von Luft zwischen der Kammer und dem Innenraum. Um eine gewünschte Verteilung der Kühlwirkung im Innenraum, d.h. im Allgemeinen eine möglichst gleichmäßige Verteilung der Temperatur in einem zusammenhängenden Fach des Innenraums und/oder gezielt unterschiedliche Temperaturen in voneinander getrennten Fächern des Innenraums, zu erzielen, wird ein Verteilerkanal vorgesehen, der dazu dient, Kaltluft aus der Kammer über an verschiedenen Stellen des Innenraums verteilte Ausblasöffnungen in den Innenraum abzugeben oder von verschiedenen Stellen abzuziehen und der Kammer zuzuführen.In the so-called no-frost refrigerators, an evaporator is housed in a chamber separated from the interior, and the interior is cooled by circulating air between the chamber and the interior. In order to achieve a desired distribution of the cooling effect in the interior, i. In general, a uniform distribution of the temperature in a contiguous compartment of the interior and / or specifically to achieve different temperatures in separate compartments of the interior, a distribution channel is provided, which serves to distribute cold air from the chamber over at different points in the interior To dispense exhaust openings in the interior or deduct from different locations and supply the chamber.
Aus DE 39 32 459 C2 ist ein Kombinationskältegerät mit einem Gefrierfach 15, einem Null-Grad-Fach 16 und Kühlfächern 17, 18 bekannt, bei dem die Verdampferkammer zwischen dem Gefrierfach und dem Null-Grad-Fach 16 untergebracht ist, ein Luftkanal 27 sich in der Rückwand des Geräts vom Null-Grad-Fach 16 zum Kühlfach 17 erstreckt und Luftkanäle 26 sich in den Seitenwänden des Geräts vom Null-Grad-Fach 17 zur Verdampferkammer erstrecken. Diese Kanäle sind jeweils in die isolierende Schaumschicht eingebettet. Da die zum Teil kompliziert geformten Kanäle als Einzelteile vorgefertigt werden müssen und an ihren Enden jeweils dicht an passend in den Innenbehälter geschnittenen Öffnungen montiert werden müssen, ist die Montage dieses Kältegeräts aufwändig und kostspielig.From DE 39 32 459 C2 a combination refrigerator with a freezer compartment 15, a zero-degree compartment 16 and cooling compartments 17, 18 is known in which the evaporator chamber is housed between the freezer compartment and the zero-degree compartment 16, an air duct 27 itself extends in the rear wall of the device from the zero-degree compartment 16 to the cooling compartment 17 and air ducts 26 extend in the side walls of the device from the zero-degree compartment 17 to the evaporator chamber. These channels are each embedded in the insulating foam layer. Since the sometimes complicated shaped channels must be prefabricated as individual parts and must be mounted at their ends in each case closely fitting in the inner container cut openings, the assembly of this refrigerator is complex and costly.
DE 101 43 242 A1 beschreibt ein Kältegerät, bei dem ein Kaltluftkanal an der Innenseite des Innenbehälters ausgebildet ist. Er erstreckt sich entlang der Decke und der Tür des Kältegeräts. Während der an der Türinnenseite verlaufende Teil des Kanals das nutzbare Volumen des Innenraums kaum beeinträchtigt und überdies den Vorteil hat, als Halterung für Türabsteller dienen zu können, beeinträchtigt der an der Decke verlaufende Kanal merklich die Nutzungsmöglichkeiten des oberen Bereich des Innenraums. Würde man einem Kanal mit dem aus DE 101 43 242 A1 an der Rückwand des Innenbehälters platzieren, wären die Einschränkungen sogar noch schwerwiegender.DE 101 43 242 A1 describes a refrigeration device in which a cold air duct is formed on the inside of the inner container. It extends along the ceiling and the door of the refrigerator. During the running on the inside of the door part of the channel the usable Volume of the interior hardly affected and also has the advantage of being able to serve as a holder for door racks, affects the running on the ceiling channel noticeably the uses of the upper portion of the interior. If you were to place a channel with the DE 101 43 242 A1 on the rear wall of the inner container, the restrictions would be even more serious.
Aufgabe der Erfindung ist, einen Korpus für ein Kältegerät zu schaffen, bei dem ein Luftkanal einfach und preiswert anzubringen ist, ohne die Nutzungsmöglichkeiten des Innenraums wesentlich zu beeinträchtigen.The object of the invention is to provide a body for a refrigeration device, in which an air duct is simple and inexpensive to install, without significantly affecting the potential uses of the interior.
Die Aufgabe wird gelöst durch einen Korpus mit den Merkmalen des Anspruchs 1. Indem der Kanal in einer Wand des Innenbehälters mitangeformten z. B. tiefgezogenen Nut angeordnet ist, entfällt die Notwendigkeit, eine den Kanal vom Innenraum abgrenzende Deckplatte weit und störend in den Innenraum vorspringen zu lassen, um einen benötigten Kanalquerschnitt zu realisieren. Gleichzeitig ist die als Luftkanal dienende Nut an ihren geschlossenwandig ausgebildeten Nutseiten in das Wärmeisolationsmaterial des Kältegerätekorpus eingebettet und damit gleichzeitig wärmeisoliert.The object is achieved by a body with the features of claim 1. By the mitanggested in a wall of the inner container z. B. deep-drawn groove is disposed of, eliminating the need to project a channel delimiting the interior of the cover plate far and disturbing in the interior to realize a required channel cross-section. At the same time serving as an air duct groove is embedded in its closed-walled groove sides in the heat insulating material of the refrigeration unit body and thus simultaneously thermally insulated.
Vorzugsweise ist der Überstand der Deckplatte über an die Nut angrenzende Wandbereiche des Innenbehälters kleiner ist als die Tiefe der Nut.Preferably, the supernatant of the cover plate is smaller than the depth of the groove via adjacent to the groove wall portions of the inner container.
Der Überstand kann auf Null gesetzt werden, so dass die mit der Nut versehene Innenbehälterwand und die Deckplatte eine bündige Fläche ergeben. Im diesem Fall kann es für eine weite Verteilung von aus Öffnungen der Deckplatte ausströmender Luft vorteilhaft sein, die Öffnungen mit unterschiedlich ausgerichteten Lenklamellen zu versehen.The supernatant can be set to zero, so that the grooved inner container wall and the cover plate give a flush surface. In this case, for a wide distribution of air flowing out of openings of the cover plate, it may be advantageous to provide the openings with differently oriented guide blades.
Ein geringer Überstand der Deckplatte kann jedoch durchaus wünschenswert sein; zum einen, weil die zum Formen des Innenbehälters verwendete Tiefziehtechnik zu streuenden Abmessungen der Nut führen kann, die eine exakt bündige Anbringung der Deckplatte schwierig machen; zum anderen ermöglichen über die Behälterwand vorstehende Flanken der Deckplatte die Anbringung von in verschiedene Richtungen ausgerichteten Ausströmöffnungen. Um eine Rundung der Innenbehälterwand am Rand der Nut zu verdecken, an der sich sonst schwer zu beseitigender Schmutz sammeln könnte, ist die Deckplatte vorzugsweise mit Randstreifen versehen, die an an die Nut angrenzenden Wandbereichen des Innenbehälters anliegen.However, a slight projection of the cover plate may well be desirable; on the one hand, because the thermoforming technique used to form the inner container can lead to scattering dimensions of the groove, which make a precisely flush attachment of the cover plate difficult; on the other hand, flanks of the cover plate which project beyond the container wall permit the attachment of outflow openings aligned in different directions. In order to conceal a rounding of the inner container wall at the edge of the groove, which could otherwise collect difficult to remove dirt, the cover plate is preferably provided with edge strips which rest against adjacent to the groove wall portions of the inner container.
Zur Verankerung der Deckplatte können von ihr abstehende und an Seitenwänden der Nut anliegende Stege vorgesehen sein.To anchor the cover plate may be provided by her projecting and applied to side walls of the groove webs.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen, die Bezug nimmt auf die beigefügten Figuren. Es zeigen:Further features and advantages of the invention will become apparent from the following description of exemplary embodiments, which refers to the attached figures. Show it:
Fig. 1 einen schematischen vertikalen Schnitt durch einen Kältegerätekorpus gemäß der Erfindung;1 shows a schematic vertical section through a refrigerator body according to the invention.
Figs. 2 bis 6 jeweils einen horizontalen Schnitt durch einen Kanal des Kältegeräts in verschiedenen Ausgestaltungen.Figs. 2 to 6 are each a horizontal section through a channel of the refrigerator in various configurations.
Der schematische Schnitt der Fig. 1 zeigt einen Kältegerätekorpus mit einer Außenwand 1 , einem tiefgezogenen Innenbehälter 2 und einer zwischen beiden eingeschlossenen Isolierschaumschicht 3. Der Innenbehälter begrenzt zwei Fächer, ein oberes Fach oder Gefrierfach 4 und ein unteres Fach oder Normalkühlfach 5. Eine Zwischenwand 6 zwischen den Fächern 4, 5 enthält eine Kammer 7, in der ein nicht gezeigter Verdampfer untergebracht ist.The schematic section of Fig. 1 shows a refrigerator body with an outer wall 1, a deep-drawn inner container 2 and an enclosed between both Isolierschaumschicht 3. The inner container defines two compartments, an upper compartment or freezer compartment 4 and a lower compartment or normal refrigeration compartment 5. An intermediate wall between the compartments 4, 5 contains a chamber 7, in which a not shown evaporator is housed.
In der Rückwand der Fächer 4, 5 ist beim Tiefziehen mittig jeweils eine Nut 7 bzw. 8 geformt, die sich von der Zwischenwand 6 aus vertikal erstreckt.In the rear wall of the compartments 4, 5, a groove 7 or 8 is formed in each case during deep drawing, which extends vertically from the intermediate wall 6 from.
Die zwei Fächer 4, 5 können mitsamt der Außenhaut der Zwischenwand 6 beim Tiefziehen des Innenbehälters ausgeformt werden; in diesem Fall ist an den Enden der Nuten 7, 8 in Höhe der Zwischenwand 6 jeweils eine Öffnung in den Innenbehälter 2 geschnitten, und die zwei Nuten sind durch einen schaumseitig eingefügten, mit der Kammer 7 kommunizierenden Kanalabschnitt 9 verbunden. Es ist aber auch möglich, beim Tiefziehen des Innenbehälters 2 zunächst nur ein Fach zu formen, das durch nachträgliches Einbauen der Zwischenwand 6 in die zwei Fächer 4, 5 unterteilt wird. In diesem gehen die zwei Nuten 7, 8 in Höhe der Zwischenwand 6 kontinuierlich ineinander über, und es ist nicht erforderlich, eine Öffnung in den Innenbehälter zu schneiden, um eine Verbindung zwischen der Kammer und den Kanälen herzustellen.The two compartments 4, 5 can be formed together with the outer skin of the intermediate wall 6 during deep drawing of the inner container; In this case, at the ends of the grooves 7, 8 at the level of the intermediate wall 6 in each case an opening in the inner container 2 is cut, and the two grooves are connected by a foam side inserted, communicating with the chamber 7 channel portion 9. However, it is also possible to first form only a compartment during deep drawing of the inner container 2, which is subdivided by subsequent installation of the intermediate wall 6 in the two compartments 4, 5. In this, the two grooves 7, 8 continuously merge into one another at the level of the intermediate wall 6, and it is not necessary to cut an opening in the inner container in order to establish a connection between the chamber and the channels.
An den Nuten 7, 8 in Höhe der Zwischenwand 6 angeordnete gesteuerte Klappen zum selektiven Zuführen von Kaltluft aus der Kammer 7 in die Nut 7, die Nut 8 oder beide gleichzeitig sind in der Fig. weggelassen.Controlled flaps disposed at the grooves 7, 8 at the level of the intermediate wall 6 for selectively supplying cold air from the chamber 7 into the groove 7, the groove 8 or both at the same time are omitted in the figure.
Die Nuten vom Inneren der Fächer 4, 5 jeweils durch eine Abdeckplatte 10 bzw. 11 abgegrenzt. Die Abdeckplatten sind beim hier betrachteten Ausführungsbeispiel in Abständen mit Ausströmöffnungen 12 versehen. Bei einer Abwandlung mit mehr als zwei Fächern, wie etwa vom in der bereits genannten DE 39 32 459 C2 beschriebenen Typ, könnte auch eine geschlossene Abdeckplatte verwendet werden, um einen Luftkanal an einem ersten Fach vorbei zu einem zweiten führen, ohne Luft in das erste Fach abzugeben.The grooves from the interior of the compartments 4, 5 each delimited by a cover plate 10 and 11 respectively. The cover plates are provided in the embodiment considered here at intervals with outflow openings 12. In a variant with more than two compartments, such as of the type described in the aforementioned DE 39 32 459 C2, a closed cover plate could also be used to guide an air duct past a first compartment to a second, without air in the first To give a subject.
Fig. 2 zeigt einen Schnitt entlang der in Fig. 1 mit X-X bezeichneten Linie gemäß einer ersten Ausgestaltung. Die Nut 8 hat einen flach rechteckigen Querschnitt und begrenzt zusammen mit der Abdeckplatte 11 einen Luftkanal 13, durch den Luft von der Kammer 7 zum Fach 5 geführt wird. Die in der Schnittebene liegenden Ausströmöffnungen 12 sind mit Lenklamellen 14 versehen, die den abgegebenen Luftstrom jeweils aus der Schnittebene der Fig. 1 heraus nach rechts bzw. links ablenken.FIG. 2 shows a section along the line designated X-X in FIG. 1 according to a first embodiment. The groove 8 has a flat rectangular cross section and, together with the cover plate 11, defines an air channel 13, through which air is guided from the chamber 7 to the compartment 5. The outflow openings 12 lying in the sectional plane are provided with guide lamellae 14, which divert the discharged air flow respectively out of the sectional plane of FIG. 1 out to the right or left.
Die Abdeckplatte 11 ist hier bündig mit die Nut 8 umgebenden Bereichen 15 der Innenbehälter-Rückwand angeordnet. Sie ist in dieser Stellung durch Stege 16 gehalten, die von den Längskanten der Abdeckplatte 11 abstehend ins Innere der Nut 8 eingreifen, zwischen deren Seitenflanken 17 geklemmt sind und sich am Boden 18 der Nut 8 abstützen.The cover plate 11 is here arranged flush with the groove 8 surrounding areas 15 of the inner container rear wall. It is held in this position by webs 16 which project from the longitudinal edges of the cover 11 protruding into the interior of the groove 8, are clamped between the side edges 17 and are supported on the bottom 18 of the groove 8.
Eine genaue Bündigkeit der Abdeckplatte 11 mit den umgebenden Bereichen 15 erfordert eine hohe Genauigkeit beim Formen der Nut 8, da bereits kleine Abweichungen störend auffallen. Solche Abweichungen sind weniger auffällig, wenn ein geringer Überstand der Deckplatte 11 über die umgebenden Bereiche 15 der Rückwand vorgesehen wird. Der Überstand kann sinnvollerweise zwischen wenigen Millimetern und 2 cm betragen, er ist in jedem Falle kleiner als die Tiefe der Nut 8. Fig. 3 zeigt ein Ausführungsbeispiel mit überstehender Abdeckplatte 11 ; der Überstand ist hier groß genug, dass Ausströmöffnungen 19 an den die Abdeckplatte 11 verankernden Stegen 16 vorgesehen werden können. Aus diesen Öffnungen 19 strömende Luft fließt zunächst an der Rückwand des Innenbehälters entlang und verteilt sich so über die Breite des Fachs 5, ohne dass Kühlgut direkt angeströmt wird.A precise flush of the cover plate 11 with the surrounding areas 15 requires a high accuracy in forming the groove 8, since even small deviations disturbing notice. Such deviations are less conspicuous if a slight projection of the cover plate 11 is provided over the surrounding regions 15 of the rear wall. The supernatant can usefully be between a few millimeters and 2 cm, it is smaller than the depth of the groove 8 in each case. Figure 3 shows an embodiment with protruding cover plate 11; the supernatant is large enough here that discharge openings 19 can be provided on the webs 16 anchoring the cover plate 11. Air flowing out of these openings 19 initially flows along the rear wall of the inner container and thus distributes itself over the width of the compartment 5, without any refrigerated goods flowing directly to it.
Die Stege 16 sind im Vergleich zur Ausgestaltung der Fig. 2 verkürzt. Seitlich von ihnen abstehende Noppen 20verrasten die Deckplatte 11 , indem sie in Vertiefungen an den Flanken 17 der Nut 8 eingreifen.The webs 16 are shortened compared to the embodiment of FIG. Laterally projecting nubs 20ververasten the cover plate 11 by engaging in recesses on the flanks 17 of the groove 8.
In der Ausgestaltung der Fig. 4 sind an den Stegen 16 seitlich abstehende Randstreifen 21 angeformt, die die an die Nut 8 angrenzenden Randbereiche 15 der Rückwand ein Stück weit überdecken und so einen Zwickel 22 abschließen und vor Verschmutzung schützen, der sich durch einen abgerundeten Übergang zwischen der Rückwand und den Seitenflanken 17 der Nut ergibt.In the embodiment of FIG. 4 16 laterally projecting edge strips 21 are integrally formed on the webs, which cover the adjoining the groove 8 edge portions 15 of the rear wall a piece and thus complete a gusset 22 and protect against contamination, which is characterized by a rounded transition between the rear wall and the side edges 17 of the groove results.
Bei der Ausgestaltung der Fig. 5 ist zwischen der Nut 8 und den angrenzenden Bereichen 15 der Rückwand jeweils ein Übergangsstreifen 23 um eine Tiefe rückversetzt, die der Dicke von über die Stege 16 seitlich überstehenden Randstreifen 21 der Deckplatte 11 entspricht. In Kombination mit einer Verrastung der Stege 16 an den Seitenflanken 17 der Nut ist hier eine exakte Bündigkeit der Abdeckplatte 11 mit der Rückwand vergleichsweise einfach realisierbar.In the embodiment of FIG. 5, in each case a transition strip 23 is set back by a depth between the groove 8 and the adjacent regions 15 of the rear wall, which corresponds to the thickness of the edge strips 21 of the cover plate 11 protruding laterally beyond the webs 16. In combination with a locking of the webs 16 on the side edges 17 of the groove an exact flush of the cover plate 11 with the rear wall is comparatively easy to implement here.
Bei der Ausgestaltung der Fig. 6 sind die Stege 16 zu einzelnen Armen 24 reduziert, die durch Ausschnitte voneinander getrennt sind. Der Schnitt dieser Fig. erstreckt sich in Höhe zweier solcher Ausschnitte. Die Ausschnitte fungieren als Ausströmöffnungen, die hinter die Deckplatte 11 bündig verbreiternden, von der Rückwand beabstandeten Randstreifen 20 verborgen sind. In the embodiment of FIG. 6, the webs 16 are reduced to individual arms 24 which are separated by cutouts. The section of this figure extends in height of two such cutouts. The cutouts act as outflow openings, which are concealed behind the cover plate 11 flush widening, spaced from the rear wall edge strip 20.
