Description

Kältegerät mit Ventilator  Refrigeration unit with fan
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit wenigstens einer Kammer und einem darin montierten Ventilator. Ventilatoren werden in Haushaltskältegeräten in diversen Einbausituationen eingesetzt, zum Beispiel zum Antreiben von Luftzirkulation in einer Lagerkammer, zur Luftumwälzung zwischen einer Lagerkammer und einer Verdampferkammer, etc. Einem verbreiteten Konstruktionsprinzip zufolge wird ein zusammenhängender Innenraum des Gehäuses eines Kältegeräts durch das Einfügen einer Zwischenwand in zwei Kammern, insbesondere Verdampfer- und Lagerkammer, unterteilt, und ein Ventilator, der zum Antreiben der Luftzirkulation zwischen den beiden Kammern dienen soll, wird vorab in der Zwischenwand montiert und in einem Arbeitsgang mit dieser eingebaut. Hierfür müssen an der Zwischenwand The present invention relates to a refrigerator, in particular a domestic refrigerator, with at least one chamber and a fan mounted therein. Fans are used in household refrigerators in various installation situations, for example, for driving air circulation in a storage chamber, for air circulation between a storage chamber and an evaporator chamber, etc. According to a common design principle, a continuous interior of the housing of a refrigerator by inserting a partition in two chambers , in particular evaporator and storage chamber, divided, and a fan, which is to serve for driving the air circulation between the two chambers, is mounted in advance in the partition and installed in one operation with this. For this must be on the partition
Konturen ausgebildet sein, die die Einbauorientierung des Ventilators festlegen, um sicherzustellen, dass dieser in die richtige Richtung bläst, und die dem Ventilator festen Halt geben. Diese Konturen verkomplizieren die Gestalt der Zwischenwand und folglich auch die zu ihrer Fertigung benötigten Formwerkzeuge. Geringfügige Änderungen in der äußeren Gestalt der Ventilatoren, die zum Beispiel auftreten können, wenn Ventilatoren verschiedener Hersteller eingebaut werden sollen, erfordern regelmäßig eine Anpassung der entsprechenden Konturen der Zwischenwand. Jede dafür erforderliche Anpassung der Werkzeuge verursacht erhebliche Kosten. Contours are formed, which determine the installation orientation of the fan to ensure that it blows in the right direction, and give the fan firm hold. These contours complicate the shape of the intermediate wall and consequently also the molds required for their production. Minor changes in the outer shape of the fans, which may occur, for example, when fans from different manufacturers are to be installed, regularly require adaptation of the corresponding contours of the intermediate wall. Any necessary adjustment of the tools causes considerable costs.
Die in verschiedenen Kältegerätemodellen verwendeten Zwischenwände können grundlegend unterschiedliche Formen und Funktionen haben; so kann zum Beispiel eine Zwischenwand eine Verdampferkammer vom Innenraum abtrennen, die einen The partitions used in various refrigerator models may have fundamentally different shapes and functions; For example, an intermediate wall separating an evaporator chamber from the interior, the one
ausreichenden Querschnitt haben muss, um darin einen Verdampfer unterzubringen, oder es kann sich bei dem abgetrennten Bereich um einen einfachen Strömungskanal handeln, dessen Querschnitt deutlich kleiner sein kann als der einer Verdampferkammer. Die Zwischenwand kann sich an einer Decke oder an einer vertikalen Wand, meist der Rückwand, des Innenraums entlang ziehen. Auch die Blasrichtung des Ventilators kann je nach Anwendung variieren. Für jede dieser Anwendungen muss eine Zwischenwand mit angepasster Gestalt bereitgestellt werden, und jede dieser Zwischenwände benötigt passende Konturen für die Fixierung des Ventilators. Aufgabe der Erfindung ist, ein Kältegerät mit einem Ventilator bereit zu stellen, das mit geringem Aufwand an Änderungen der Gestalt des Ventilators anpassbar ist und/oder die Fertigung diverser Modelle, die sich in der Einbausituation des Ventilators unterscheiden, mit geringen Kosten ermöglicht. Die Aufgabe wird gelöst, indem bei einem Kältegerät mit einem Gehäuse, das wenigstens einen Innenraum umgibt, wobei der Innenraum einen Ventilator und eine den Innenraum unterteilende Ventilatorabdeckung enthält, der Ventilator in den Innenraum mittels eines Trägers montiert ist, der als von der Ventilatorabdeckung getrenntes Bauteil ausgebildet ist und ein Ventilatorfach aufweist, in das der Ventilator in zwei verschiedenen must have sufficient cross-section to accommodate an evaporator therein, or it may be in the separated area to a simple flow channel, the cross section may be significantly smaller than that of an evaporator chamber. The partition wall can be pulled along a ceiling or on a vertical wall, usually the back wall, of the interior. The blowing direction of the fan may vary depending on the application. For each of these applications, an intermediate wall of an adapted shape must be provided, and each of these intermediate walls requires suitable contours for fixing the fan. The object of the invention is to provide a refrigerator with a fan that can be adapted with little effort to changes in the shape of the fan and / or the production of various models that differ in the installation situation of the fan, allows low cost. The object is achieved by, in a refrigeration device having a housing which surrounds at least one interior space, wherein the interior contains a fan and a fan cover dividing the interior, the fan is mounted in the interior by means of a carrier, which is separated from the fan cover component is formed and has a fan compartment, in which the fan in two different
Orientierungen einfügbar ist. Orientations can be inserted.
Im Falle eines Wechsels des Ventilator genügt es bei dem erfindungsgemäßen In the case of a change of the fan, it is sufficient in the inventive

unverändert bleiben, sei es, weil der Träger mit dem Ventilator unabhängig von der Ventilatorabdeckung in dem Innenraum befestigt ist, oder, falls der Träger und der Ventilator zuerst mit der Ventilatorabdeckung verbunden und dann die so erhaltene Baugruppe in das Gehäuse eingebaut wird, diejenigen Bereiche des Trägers, die zur Befestigung an der Ventilatorabdeckung dienen, bei an unterschiedliche Ventilatormodelle angepassten Varianten des Trägers einheitlich sein können. remain unchanged, either because the support is fixed to the fan with the fan independent of the fan cover in the interior or, if the support and the fan are first connected to the fan cover and then the assembly thus obtained is installed in the housing, those areas of Beams, which serve for attachment to the fan cover, may be uniform in adapted to different fan models variants of the carrier.
Die Verwendung des Trägers ermöglicht eine Vereinfachung der Form der The use of the carrier allows a simplification of the shape of the
Ventilatorabdeckung, da diese keine unmittelbar zur Befestigung des Ventilators geeigneten Konturen aufweisen muss. Die dadurch erreichbaren Kosteneinsparungen vervielfachen sich noch, wenn unterschiedliche Modelle von Kältegeräten mit jeweils spezifischen Ventilatorabdeckungen gefertigt werden und alle diese Fan cover as it does not need to have contours suitable for mounting the fan directly. The resulting cost savings are multiplied even if different models of refrigerators are manufactured with specific fan covers and all of them
Ventilatorabdeckungen mit einem gleichen Typ von Trägern kombiniert werden.  Fan covers are combined with a same type of straps.
Indem der Träger ein Ventilatorfach aufweist, in das der Ventilator in zwei verschiedenen Orientierungen einfügbar ist, können, obwohl die Laufrichtung eines Ventilators im By the fact that the carrier has a fan compartment into which the fan can be inserted in two different orientations, although the running direction of a fan in the
Allgemeinen durch seine Verdrahtung vorgegeben ist, unterschiedliche Laufrichtungen für verschiedene Einbausituationen des Ventilators, zum Beispiel saugend an einer sich unter der Decke des Innenraums erstreckenden Verdampferkammer oder pumpend an einem sich unter der Decke erstreckenden Verteilerkanal, mit demselben Träger realisiert werden. Is generally given by its wiring, different directions of travel for different installation situations of the fan, for example, sucking on an under the ceiling of the interior extending evaporator chamber or pumping at one Under the ceiling extending distribution channel, be realized with the same carrier.
Um in jedem Fall die korrekte Laufrichtung des Ventilators zu gewährleisten, ist zweckmäßigerweise ein zu einem elektrischen Versorgungsanschluss des Ventilators komplementärer Versorgungsanschluss des Gehäuses in nur einer der zwei In order to ensure in each case the correct running direction of the fan, a complementary to an electrical supply connection of the fan supply port of the housing is expediently in only one of the two
Orientierungen des Ventilators mit dessen Versorgungsanschluss verbindbar. D.h. nicht der Träger, sondern das Gehäuse des Kältegerätes gibt die Orientierung vor, in der der Ventilator montiert werden kann. Eine bevorzugte Einbauposition des Ventilators ist an einer von Decke und Rückwand des Innenraums gebildeten Kante. Die Ventilatorabdeckung kann dann wahlweise z.B. eine sich unter der Decke erstreckende Kammer oder eine sich an der Rückwand erstreckende Kammer von dem Innenraum abteilen; in beiden Fällen kann der Ventilator einen  Orientations of the fan connectable to its supply connection. That not the carrier, but the housing of the refrigerator, the orientation in which the fan can be mounted. A preferred installation position of the fan is on an edge formed by the ceiling and rear wall of the interior. The fan cover may then optionally be e.g. separating a compartment extending below the ceiling or a compartment extending from the rear wall from the compartment; in both cases, the fan can one
Luftstrom in der abgeteilten Kammer effizient antreiben. Efficiently drive airflow in the compartmentalized chamber.
In der Kammer kann ein Verdampfer untergebracht sein. In the chamber, an evaporator can be accommodated.
Im Falle einer als Verteilerkammer benutzten Kammer können zu einer vom Ventilator abgewandten Öffnung hin divergierende Stromführungsrippen vorgesehen sein, um den geführten Luftstrom auf die gesamte Breite des Innenraums oder wenigstens einen großen Teil davon aufzufächern. In the case of a chamber used as a distributor chamber, diverging current-carrying ribs may be provided to an opening facing away from the fan in order to fan out the guided air flow over the entire width of the interior or at least a large part thereof.
Vorzugsweise ist der Träger getrennt von der Ventilatorabdeckung in dem Innenraum montierbar. So können insbesondere die erforderlichen elektrischen Kontakte zwischen dem Ventilator und dem komplementären Versorgungsanschluss am Gehäuse unbehindert durch die Ventilatorabdeckung geschlossen werden. Preferably, the carrier is mountable separately from the fan cover in the interior. In particular, the required electrical contacts between the fan and the complementary supply port on the housing can be closed unobstructed by the fan cover.
Die Ventilatorabdeckung kann auch schwenkbar mit dem Träger verbunden sein, sei es, um, wenn Träger und Ventilatorabdeckung gemeinsam montiert werden, nach dem Befestigen des Trägers die Abdeckung schnell und positionsgenau davor klappen zu können, sei es um erst nach der Befestigung des Trägers in dem Innenraum die The fan cover may also be pivotally connected to the carrier, either to allow the carrier and fan cover to be mounted together, after attaching the carrier, to be able to quickly and accurately position the cover in front of it, be it only after the carrier has been secured in the carrier Interior the

Insbesondere in letzterem Fall ist es zweckmäßig, dass ein die Ventilatorabdeckung mit dem Träger verbindendes Gelenk einen Achskörper und eine den Achskörper nur auf einem Teil seines Umfangs umgebende Hülse oder Rinne umfasst, so dass die das Gelenk bildenden Komponenten nach dem Einbau des Trägers quer zur Schwenkachse des Gelenks zusammengefügt werden können. Hang the cover on the carrier and fold it in front. Particularly in the latter case, it is expedient that a joint connecting the fan cover to the carrier comprises an axle body and a sleeve or groove surrounding the axle body only on a part of its circumference, so that the components forming the joint are transverse to the pivot axis after installation of the carrier of the joint can be joined together.
Die Ventilatorabdeckung und der Träger können zweckmäßigerweise ineinander greifende Rastmittel aufweisen, um die Befestigung der Ventilatorabdeckung zu beschleunigen; insbesondere können diese Rastmittel so angeordnet sein, dass sie durch ein Schwenken der Ventilatorabdeckung in dem Gelenk gegeneinander geführt und zum Einrasten gebracht werden. The fan cover and the carrier may conveniently have interengaging latching means to accelerate attachment of the fan cover; In particular, these locking means may be arranged so that they are guided by pivoting the fan cover in the joint against each other and brought to lock.
Die Erfindung erlaubt es, bei einem Kältegerät mit zwei Innenräumen, in denen jeweils ein Ventilator mittels eines Trägers montiert ist, mit Hilfe identischer Träger beide Ventilatoren unterschiedlich orientiert anzubringen, sei es, um einen Luftstrom in der einen Kammer entlang der Decke und in der anderen entlang der Rückwand zu pumpen, oder einenThe invention makes it possible, in a refrigeration device with two interiors, in each of which a fan is mounted by means of a carrier, with the help of identical support both fans differently oriented to install, be it an air flow in one chamber along the ceiling and in the other to pump along the back wall, or one

Fig. 1 zeigt eine Ventilatorbaugruppe zum Einbau in einem Kältegerät wie etwa einem Haushaltskühlschrank oder -gefrierschrank gemäß der Erfindung in einer auseinander gezogenen perspektivischen Ansicht. Sie umfasst einen Ventilator 1 und einen aus Kunststoff spritzgeformten Träger 2. Der Ventilator 1 ist von an sich bekannter Bauart, mit einem flach quaderförmigen Rahmen 3, in dem sich zwischen den zwei quadratischen Hauptoberflächen ein zylindrischer Durchgang 4 erstreckt, einem in dem Durchgang 4 montierten Schaufelrad 5 und einem in einer Nabe 6 des Schaufelrades 5 Fig. 1 shows a fan assembly for installation in a refrigerator such as a household refrigerator or freezer according to the invention in an exploded perspective view. It comprises a fan 1 and a plastic injection-molded carrier 2. The fan 1 is of a type known per se, with a flat cuboid frame 3, in which a cylindrical passage 4 extends between the two main square surfaces, one mounted in the passage 4 Paddle wheel 5 and one in a hub 6 of the paddle wheel fifth
untergebrachten Antriebsmotor. Ein Versorgungskabel des Motors durchzieht eine die Nabe 6 mit dem Rahmen 3 verbindende Speiche 7 und tritt an einer Anschlussstelle 8 an einer ausgesparten Ecke des Rahmens 3 ins Freie. Ein Kabelstück 9, dessen Länge deutlich kleiner ist als die Kantenlänge des Rahmens 3, erstreckt sich zwischen der Anschlussstelle 8 und einem Stecker 10. housed drive motor. A supply cable of the motor passes through a hub connecting the hub 6 with the frame 3 spoke 7 and occurs at a junction 8 at a recessed corner of the frame 3 to the outside. A cable piece 9, the length of which is significantly smaller than the edge length of the frame 3, extends between the connection point 8 and a plug 10.
Der Träger 2 hat im Wesentlichen die Form eines einseitig, vorzugsweise oben, offenen Kastens, durch dessen offene Seite der Ventilator 1 in ein Fach 1 1 des Trägers 2 einschiebbar ist. Die Abmessungen von Fach 1 1 und Rahmen 3 sind so aneinander angepasst, dass der Ventilator 1 reibschlüssig in dem Träger 2 gehalten ist, wobei gegebenenfalls Pufferschichten zwischen dem Rahmen 3 und den Innenseiten des Fachs 1 1 vorgesehen sein können. The carrier 2 has essentially the shape of a one-sided, preferably top, open box, through the open side of the fan 1 in a compartment 1 1 of the carrier 2 is inserted. The dimensions of compartment 1 1 and frame 3 are adapted to each other so that the fan 1 is frictionally held in the carrier 2, wherein optionally buffer layers between the frame 3 and the insides of the compartment 1 1 may be provided.
Seitenwände 12 des Trägers 2 sind über eine Rückwand 13 des Fachs 1 1 hinaus nach hinten verlängert, um einen dichten Anschluss an einem Kältegeräte-Innenbehälter herzustellen, wie später noch deutlicher wird. Beide Seitenwände 12 tragen jeweils einen rückseitig offenen Vorsprung 14, in dessen Vorderseite eine Schrauböffnung 15 ausgespart ist. Eine nach oben und nach hinten offene Aussparung 16 an der Oberseite jedes Vorsprungs 14 ist bemessen, um den Stecker 10 mit nach hinten überstehenden Steckstiften 17 aufzunehmen, wobei in der in Fig. 1 gezeigten Orientierung des Ventilators 1 die Länge des Kabelstücks 9 eine Side walls 12 of the carrier 2 are extended rearwardly beyond a rear wall 13 of the compartment 1 1, to produce a tight connection to a refrigerator inner container, as will become clear later. Both side walls 12 each carry a rearwardly open projection 14, in the front side of a screw opening 15 is recessed. An upwardly and rearwardly open recess 16 at the top of each projection 14 is dimensioned to receive the plug 10 with rearwardly projecting plug pins 17, wherein in the orientation of the fan 1 shown in Fig. 1, the length of the cable piece 9 a
Anbringung des Steckers 10 nur in der rechten Aussparung 16 zulässt. Um den Stecker 10 in der linken Aussparung platzieren zu können, müsste der Ventilator 1 um eine vertikale Achse um 180° gedreht werden, wodurch sich die Richtung des von ihm erzeugten Luftstroms umkehren würde. An den von dem Fach 1 1 abgewandten  Attachment of the plug 10 only in the right-hand recess 16 allows. In order to be able to place the plug 10 in the left-hand recess, the fan 1 would have to be rotated by 180 ° about a vertical axis, whereby the direction of the air flow generated by it would be reversed. At the remote from the compartment 1 1
Außenflächen der Vorsprünge 14 ist jeweils eine Rastnase 24 geformt. Outside surfaces of the projections 14, a detent 24 is formed in each case.
Fig. 2 zeigt die Baugruppe aus Ventilator 1 und Träger 2 im zusammengefügten Zustand vor einem Stück eines Innenbehälters des Kältegeräts. Der in dem Fachmann bekannter Weise durch Tiefziehen geformte Innenbehälter hat eine Decke 18, eine Rückwand 19 und zwei an einer Kante zwischen Decke 18 und Rückwand 19 ausgeformte, in den Innenbehälter hinein vorspringende Schraubdome 20. Die Schraubdome 20 sind entsprechend dem Abstand zwischen den Vorsprüngen 14 des Gestells 2 angeordnet, so dass der Träger 2 an den Schraubdomen 20 verschraubt werden kann. Oberhalb eines Schraublochs 21 des rechten Schraubdoms 20 ist ein Steckverbinder 22 mit zu den Steckstiften 17 komplementären Buchsen 23 in eine Öffnung des Fig. 2 shows the assembly of fan 1 and 2 carrier in the assembled state in front of a piece of an inner container of the refrigerator. The inner container, formed by deep-drawing in the manner known to the person skilled in the art, has a cover 18, a rear wall 19 and two screw domes 20 formed on an edge between cover 18 and rear wall 19 and projecting into the inner container. The screw domes 20 correspond to the distance between the projections 14 arranged the frame 2, so that the carrier 2 can be screwed to the screw 20 dome. Above a screw hole 21 of the right screw dome 20 is a connector 22 with complementary to the pins 17 sockets 23 in an opening of the
Innenbehälters eingefügt. Die Baugruppe aus Ventilator 1 und Träger 2 ist am Inner container inserted. The assembly of fan 1 and 2 carrier is on
Innenbehälter nur dann montierbar, wenn ihr Stecker 10 sich in der Aussparung 16 des rechten Vorsprungs 14 befindet, so dass seine Steckstifte 17 in die Buchsen 23 eingreifen können. Wäre der Ventilator 1 mit der falschen Orientierung in das Fach 1 1 Inner container can only be mounted if their connector 10 is in the recess 16 of the right projection 14, so that its plug pins 17 can engage in the sockets 23. If the fan 1 with the wrong orientation in the tray 1 1
eingeschoben, dann könnte sein Stecker 10 nur am linken Vorsprung 14 platziert werden; in diesem Fall würden seine Steckstifte 17 gegen die geschlossene Stirnfläche des linken Schraubdoms 20 stoßen, und eine ordnungsgemäße Montage, wie in Fig. 3 gezeigt, bei der durch die Schrauböffnungen 15 in die Löcher 21 eingreifende Schrauben 25 die Vorsprünge 14 an dem Schraubdom 20 fixieren und einen sicheren Eingriff der Steckstifte 17 in die Buchsen 23 garantieren, wäre nicht möglich. Wiederum bezogen auf Fig. 1 erkennt man an einer hinteren unteren Ecke der rechten Seitenwand 12 eine im Querschnitt kreisbogenförmige Hülse 26. Eine entsprechende, zu der gezeigten Hülse 26 koaxiale Hülse ist auch außen an die linke Seitenwand 12 angeformt. Die beiden Hülsen 26 definieren eine Schwenkachse für eine Ventilatorabdeckung 27, von der eine erste Ausgestaltung in Fig. 4 in einem schematischen Schnitt gezeigt ist. Die Ventilatorabdeckung 27 umfasst zwei vertikale Seitenflanken 28, die den Träger 2 auf beiden Seiten umgreifen, eine die Seitenflanken 28 einteilig verbindende Bodenplatte 29 und eine Frontplatte 30, die mit der Bodenplatte 29 durchgehend entlang einer unteren Kante und mit den Seitenflanken 28 über zwei Streben 31 verbunden ist. Zwei zylindrische Zapfen 32 an den einander zugewandten Oberflächen der Seitenflanken 28 sind in die Hülsen 26 eingefügt. So ist die Ventilatorabdeckung 27 aus der in Fig. 4 gezeigten Stellung im Gegenuhrzeigersinn um eine von den Hülsen 26 und den Zapfen 32 festgelegte Achse in eine Raststellung schwenkbar, in der die oberen und hinteren Kanten der Seitenflanken 28 eng an der Decke 18 bzw. der Rückwand 19 des inserted, then his plug 10 could be placed only on the left projection 14; In this case, its plug pins 17 would abut against the closed end face of the left screw dome 20, and a proper assembly, as shown in Fig. 3, in which by the screw holes 15 into the holes 21 engaging screws 25 fix the projections 14 on the screw dome 20 and guarantee a secure engagement of the pins 17 in the sockets 23, would not be possible. Referring again to Fig. 1 can be seen at a rear lower corner of the right side wall 12 has a circular cross-section sleeve 26. A corresponding, coaxial to the sleeve 26 shown sleeve is also formed on the outside of the left side wall 12. The two sleeves 26 define a pivot axis for a fan cover 27, of which a first embodiment in Fig. 4 is shown in a schematic section. The fan cover 27 comprises two vertical side flanks 28, which surround the carrier 2 on both sides, a bottom plate 29 integrally connecting the side flanks 28 and a front plate 30, which is continuous with the bottom plate 29 along a lower edge and with the side flanks 28 via two struts 31 connected is. Two cylindrical pins 32 on the mutually facing surfaces of the side edges 28 are inserted into the sleeves 26. Thus, the fan cover 27 is pivoted from the position shown in Fig. 4 in a counterclockwise direction about an axis defined by the sleeves 26 and the pin 32 in a locking position in which the upper and rear edges of the side edges 28 close to the ceiling 18 and Rear wall 19 of the
Innenbehälters anliegen, ein Zwischenraum zwischen der Oberkante der Frontplatte 30 und der Decke 18 sowie freie Durchgänge oberhalb und unterhalb der Streben 31 Ansaugöffnungen für den Ventilator 1 bilden und eine Lücke zwischen der Rückwand 19 und einer Hinterkante der Bodenplatte 29 eine Ausblasöffnung für einen vertikal nach unten gerichteten Luftstrom bildet. Die Ventilatorabdeckung 27 ist in der Raststellung fixiert durch Eingriff der zwei Rastnasen 24 des Trägers 2 in Ausschnitte 33 an der Oberkante der Seitenflanken 28.  Abut the inner container, a gap between the upper edge of the front panel 30 and the ceiling 18 and free passages above and below the struts 31 suction for the fan 1 form and a gap between the rear wall 19 and a trailing edge of the bottom plate 29 is a blow-out for a vertical downward directed air flow forms. The fan cover 27 is fixed in the locking position by engagement of the two latching lugs 24 of the carrier 2 in cutouts 33 at the upper edge of the side edges 28th
Die Figuren 5 und 6 zeigen jeweils einen partiellen Längsschnitt durch ein Figures 5 and 6 each show a partial longitudinal section through a
Kältegerätegehäuse mit der bereits beschriebenen Ventilatorbaugruppe aus Ventilator 1 und Träger 2 und mit einer Ventilatorabdeckung 34 gemäß einer zweiten Ausgestaltung bzw. eine schematische Draufsicht auf die Ventilatorbaugruppe und die Refrigeration appliance housing with the already described fan assembly of fan 1 and support 2 and with a fan cover 34 according to a second embodiment or a schematic plan view of the fan assembly and the
Ventilatorabdeckung 34. An der Decke 18 des Innenbehälters ist hier eine flache Fan cover 34. At the ceiling 18 of the inner container is here a flat
Hinterschneidung 35 ausgeformt, die sich über die gesamte Breite des Innenraums und von der Rückwand 19 ausgehend fast über seine gesamte Tiefe erstreckt. Die Undercut 35 formed, which extends over the entire width of the interior and from the rear wall 19, starting almost over its entire depth. The
Ventilatorbaugruppe ist mittig an einer von Decke 18 und Rückwand 19 gebildeten Kante des Innenbehälters montiert. Die Ventilatorabdeckung 34 besteht zu einem großen Teil aus einer flachen horizontalen Platte 36, die die Hinterschneidung 35 mit Ausnahme eines vorderen Randbereichs 37 verdeckt. Am hinteren Rand der Abdeckung 34 ist mittig eine nach unten gerichtete Ausbuchtung 38 geformt, die die Ventilatorbaugruppe aufnimmt. Innerhalb der Fan assembly is mounted centrally on an edge formed by the ceiling 18 and rear wall 19 of the inner container. The fan cover 34 consists to a large extent of a flat horizontal plate 36, which conceals the undercut 35 except for a front edge portion 37. At the rear edge of the cover 34, a downwardly directed bulge 38 is centrally formed, which receives the fan assembly. Within the
Ausbuchtung 38 sind zwei vertikale Wände 39 parallel zu den Seitenwänden 12 des Trägers 2 geformt, die wie die Seitenwände 28 der ersten Ausgestaltung an ihrerBulge 38 are two vertical walls 39 formed parallel to the side walls 12 of the carrier 2, which like the side walls 28 of the first embodiment of their
Oberkante mit Ausschnitten 33 versehen sind, in die die Rastnasen 24 des Trägers 2 eingreifen. An diese Wände 39 schließen nach vorn Wände 40 an, die sich über die Oberseite der ebenen Platte 36 erstrecken, die Decke 18 berühren und an den zwei vorderen Ecken der Platte 36 enden. In einem vorderen Bereich der Platte 36 sind zwischen den divergierenden Wänden 40 ebenfalls nach vorn divergierende Upper edge are provided with cutouts 33, in which engage the latching lugs 24 of the carrier 2. Walls 40, which extend over the top of the flat plate 36, contact the ceiling 18 and terminate at the two front corners of the panel 36, are connected to these walls 39 forwardly. In a front region of the plate 36 are also diverging forward between the diverging walls 40
Luftführungsrippen 41 angeordnet. Die divergierenden Wände 40 und Luftführungsrippen 41 verteilen einen vom Ventilator 1 nach vorn angetriebenen Luftstrom über die gesamte Breite des Innenraums 1 und sorgen so für eine über die gesamte Breite des Innenraums homogene Luftumwälzung und eine gleichmäßige Temperaturverteilung.  Air guide ribs 41 arranged. The divergent walls 40 and air guide ribs 41 distribute an airflow driven forwardly by the fan 1 over the entire width of the interior 1 and thus ensure homogeneous air circulation over the entire width of the interior and a uniform temperature distribution.
Fig. 7 zeigt einen Teilschnitt durch ein Kältegerätegehäuse gemäß einer dritten Fig. 7 shows a partial section through a refrigerator housing according to a third
Ausgestaltung der Erfindung. Die Schnittebene verläuft durch das den Ventilator 1 aufnehmende Fach 1 1 des Trägers 2, allerdings ist der Ventilator 1 der Übersichtlichkeit halber in Fig. 7 nicht dargestellt. Eine an die Hülsen 26 des Trägers 2 angelenkte und an ihrem vorderen Rand an der Decke 18 des Innenbehälters verschraubte Embodiment of the invention. The sectional plane extends through the fan 1 receiving compartment 1 1 of the carrier 2, however, the fan 1 for the sake of clarity in Fig. 7 is not shown. One hinged to the sleeves 26 of the carrier 2 and bolted to its front edge on the ceiling 18 of the inner container
Ventilatorabdeckung 42 teilt hier eine Verdampferkammer mit einem Verdampfer 43 darin ab. Die Laufrichtung des Ventilators ist umgekehrt zu derjenigen der Fig. 5; der Ventilator saugt Luft von einer Eintrittsöffnung 44 am vorderen Rand der Abdeckung 42 durch die Verdampferkammer und den Verdampfer 43, um sie in einen in die Rückwand 19 eingetieften Verteilerkanal 45 auszustoßen. Der in der Rückwand 19 abwärts verlaufende Verteilerkanal 45 hat mehrere Öffnungen 46, über die die Kaltluft auf verschiedenen Höhen zurück in die Lagerkammer gelangen kann.  Fan cover 42 divides an evaporator chamber with an evaporator 43 therein. The running direction of the fan is inverse to that of FIG. 5; the fan draws air from an inlet 44 at the front edge of the cover 42 through the evaporator chamber and the evaporator 43 to expel them into a manifold 45 recessed into the back wall 19. The down in the rear wall 19 distribution channel 45 has a plurality of openings 46, through which the cold air can reach at different heights back into the storage chamber.
Der Träger 2 ist identisch mit demjenigen der vorhergehenden Ausgestaltung, die Bodenplatte 47 des Fachs 1 1 reicht nicht bis an die Rückwand 19. Statt dessen ist eine plattenförmige Abdeckung 48 des Verteilerkanals 45 mit einem vorspringenden Steg 49 versehen, der sich bis zur Hinterkante der Bodenplatte 47 erstreckt und die von dem Ventilator gegen die Rückwand 19 geblasene Luft in den Verteilerkanal 45 zwingt. Der (in den Figuren 5 bis 7 nicht dargestellte) Steckverbinder 22 befindet sich bei der Ausgestaltung der Figuren 5 und 6 einerseits und derjenigen der Fig. 7 andererseits auf jeweils verschiedenen Seiten des Fachs 1 1 , so dass in ersterem Fall eine elektrische Kontaktierung des Ventilators 1 nur dann möglich ist, wenn er mit Blasrichtung nach vorn in das Fach 1 1 eingeführt ist, wohingegen im Fall der Fig. 7 eine Kontaktierung nur mit Blasrichtung nach hinten, gegen die Rückwand 19 möglich ist. The support 2 is identical to that of the previous embodiment, the bottom plate 47 of the compartment 1 1 does not extend to the rear wall 19. Instead, a plate-shaped cover 48 of the distribution channel 45 is provided with a projecting web 49 extending to the trailing edge of the bottom plate 47 and forced by the fan against the rear wall 19 blown air into the distribution channel 45. The (not shown in Figures 5 to 7) connector 22 is located in the embodiment of Figures 5 and 6 on the one hand and that of Fig. 7 on the other hand on each different sides of the compartment 1 1, so that in the former case, an electrical contact of the fan 1 is only possible if it is introduced with blowing direction forward in the compartment 1 1, whereas in the case of Fig. 7 contacting only with blowing direction to the rear, against the rear wall 19 is possible.
