Abstract
Description
Kältegerät mit einem Lüfter Refrigeration device with a fan
Die vorliegende Erfindung betrifft ein Kältegerät. The present invention relates to a refrigeration device.
Bei vielen Kältegeräten treten Schwingungen an Lüftern auf, die über die Befestigungselemente des Lüfters beispielsweise auf einen Verdampfer des Kältegerätes übertragen und dann als Schall in die Umgebung abgestrahlt werden. Diese Schallemissionen werden als störend wahrgenommen. In many refrigerators vibrations occur on fans, which are transmitted via the fastening elements of the fan, for example, to an evaporator of the refrigerator and then emitted as sound into the environment. These sound emissions are perceived as disturbing.
Gleichzeitig fordert die Marktsituation alle Kostenpotenziale bei der Fertigung von Kältegeräten auszuschöpfen. Der Lüfter sollte daher einfach montierbar sein und die Anbringung kostengünstig realisierbar sein. At the same time, the market situation calls for exhausting all cost potentials in the production of refrigeration appliances. The fan should therefore be easy to install and the installation can be realized inexpensively.
Da Lüfter bewegte Teile, insbesondere Flügelräder, aufweisen, die einem Verschleiß unterworfen sind, ist es vorteilhaft den Lüfter einfach austauschen zu können. Der Lüfter sollte sich demnach schnell und einfach montieren und auch demontieren lassen. Since fans have moving parts, in particular impellers, which are subject to wear, it is advantageous to be able to easily replace the fan. The fan should therefore be quick and easy to assemble and disassemble.
Im Rahmen der Globalisierung der Märkte werden Kältegeräte zunehmend auch über weite Strecken, teilweise bei starken Erschütterungen, transportiert. Es ist daher gewünscht, dass der Lüfter verliersicher, auch bei Erschütterungen des Kältegerätes, am Kältegerät angebracht ist. Auf Grund der starken Unterschiede der in den verschiedenen Märkten verfügbaren Hilfsmittel ist es vorteilhaft, dass der Austausch des Lüfters ohne Spezialwerkzeug möglich ist. As part of the globalization of the markets, refrigeration appliances are increasingly being transported over long distances, sometimes with severe shocks. It is therefore desirable that the fan is captive, even with shocks of the refrigerator, mounted on the refrigerator. Due to the large differences in the tools available in the various markets, it is advantageous that the replacement of the fan without special tools is possible.
Es ist daher Aufgabe der vorliegenden Erfindung ein Kältegerät zur Verfügung zu stellen, bei dem ein Lüfter am Kältegerät, insbesondere am Verdampfer, technisch einfach, sicher bei Erschütterungen, kostengünstig und schwingungsentkoppelt anbringbar und einfach lösbar ist. It is therefore an object of the present invention to provide a refrigeration device, in which a fan on the refrigeration device, in particular on the evaporator, technically simple, safe in shock, inexpensive and vibration decoupled attachable and easily solvable.
Diese Aufgabe wird durch ein Kältegerät gemäß dem unabhängigen Anspruch 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.

Der Lüfter weist beispielsweise einen Außenläufer-Lüftermotor auf. Ein Außenläufer ist dabei eine Bauform von Elektromotoren, bei der sich der ruhende Teil (Stator) des Motors im Innern befindet und vom bewegten Teil (Rotor, „Läufer") umschlossen ist. Diese können beispielsweise Asynchronmotoren mit Kurzschlussläufer sein. Bei als Außenläufer ausgeführten elektronisch kommutierten Gleichstrommotoren besteht der Läufer beispielsweise aus mehreren abwechselnd radial ausgerichteten ringförmig angeordneten Dauermagneten oder einem entsprechend vielpolig magnetisierten Ring. Ein Kältekreislauf des Kältegerätes umfasst beispielsweise einen Verdichter zum Verdichten von Kältemitteldampf, einen dem Verdichter nachgeschalteten Verflüssiger zum Kondensieren des Kältemitteldampfes und den dem Verflüssiger nachgeschalteten und dem Verdichter vorgeschalteten Verdampfer zum Verdampfen des verflüssigten Kältemittels. Der Verflüssiger ist wie der Verdampfer zur Wärmeübertragung zwischen zugeführter Luft und dem Fluid des Kältekreislaufs eingerichtet. The fan has, for example, an external rotor fan motor. An external rotor is a type of electric motor in which the stationary part (stator) of the motor is located inside and enclosed by the moving part (rotor, "rotor"), for example asynchronous motors with squirrel-cage rotor For example, a rotor of the refrigerator includes a compressor for compressing refrigerant vapor, a condenser connected downstream of the compressor for condensing the refrigerant vapor and the condenser downstream and the condenser The condenser, like the evaporator, is used to transfer heat between the supplied air and the fluid of the refrigeration circuit erichtet.

Das jeweilige Dämpfungselement kann elastisch, beispielsweise aus Gummi hergestellt sein. Das jeweilige Dämpfungselement ermöglicht eine Lagerung vom Lüftergehäuse am Verdampfer wobei gleichzeitig eine Übertragung von Schwingungen vom Gehäuse auf den Verdampfer verhindert bzw. reduziert wird. Dadurch werden Geräuschemissionen, die durch das Abstrahlen von Schallwellen, die aus vom Gehäuse des Lüfters übertragenen Schwingungen resultieren, vom Verdampfer an die Umgebung vermieden. Die Schallemissionen des Kältegerätes werden dadurch verbessert.

Figur 1 zeigt eine schematische Darstellung eines Lüfters 5 eines Kältegerätes 1 mit einem Lüftergehäuse 1 1. An dem Lüftergehäuse 1 1 sind seitlich Lagerzapfen zum Befestigen des Lüftergehäuses 1 1 in Ausnehmungen einer Lagerschale 4 angebracht. Ein erster Lagerzapfen 13 und ein zweiter Lagerzapfen 14 sind am Lüftergehäuse 1 1 einander gegenüberliegend angeordnet. Oberhalb des ersten und zweiten Lagerzapfens 13, 14 sind ein dritter Lagerzapfen 21 und ein vierter Lagerzapfen 22 sind am Lüftergehäuse 1 1 einander gegenüberliegend angeordnet. Die Lagerzapfen 13, 14, 21 , 22 sind vorgesehen, um eine Anbringung des Lüfters 5 in der Lagerschale 4, welche an einem Verdampfer (in Fig. 1 nicht dargestellt) befestigt werden kann, zu ermöglichen. An den Lagerzapfen 13, 14, 21 , 22 sind Dämpfungselemente 17 angebracht, um den Lüfter 5 von der Lagerschale 4 und somit von dem Verdampfer schwingungstechnisch zu entkoppeln. Die Dämpfungselemente 17 sind bei diesem Ausführungsbeispiel ringförmig gestaltet und auf die Lagerzapfen 13, 14, 21 , 22 aufgesteckt. Dadurch beabstanden und dämpfen sie sowohl in axialer als auch in radialer Richtung die Lagerzapfen 13, 14, 21 , 22. Zur Arretierung des zweiten und des vierten Lagerzapfens 21 , 22 ist ein Arretierungselement 30 vorgesehen, das einen Befestigungsbügel 31 mit Arretierungshaken 33 umfasst. Der Befestigungsbügel 31 ist in Fig. 1 in der Vorderansicht dargestellt. Der Befestigungsbügel 31 verläuft in etwa halbkreisförmig entlang der Lagerschale 4. Am Befestigungsbügel 31 sind zur Arretierung des Befestigungsbügels 31 Rasthaken 35 vorgesehen. An den Enden des Befestigungsbügels 31 sind Arretierungshaken 33 vorgesehen, welche zur Arretierung des zweiten und des vierten Lagerzapfens 21 , 22 entsprechende Arretierungsaufnahmen, beispielsweise Arretierungsbolzen, hintergreifen. Figure 1 shows a schematic representation of a fan 5 of a refrigerator 1 with a fan housing 1 1. On the fan housing 1 1 bearing journals for attaching the fan housing 1 1 are mounted in recesses of a bearing shell 4 side. A first bearing journal 13 and a second bearing journal 14 are arranged opposite each other on the fan housing 1 1. Above the first and second bearing pins 13, 14, a third bearing pin 21 and a fourth bearing pin 22 are arranged on the fan housing 1 1 opposite one another. The journals 13, 14, 21, 22 are provided to allow mounting of the fan 5 in the bearing shell 4, which can be attached to an evaporator (not shown in Fig. 1). At the bearing pins 13, 14, 21, 22 damping elements 17 are mounted to decouple the fan 5 of the bearing shell 4 and thus of the evaporator vibration technology. The damping elements 17 are designed annular in this embodiment and attached to the bearing pins 13, 14, 21, 22. As a result, they space and damp the bearing journals 13, 14, 21, 22 both in the axial and in the radial direction. To lock the second and the fourth bearing pin 21, 22, a locking element 30 is provided which comprises a mounting bracket 31 with locking hook 33. The mounting bracket 31 is shown in Fig. 1 in front view. The mounting bracket 31 extends in approximately semicircular along the bearing shell 4. On mounting bracket 31 31 locking hooks 35 are provided for locking the mounting bracket. Arretierungshaken 33 are provided at the ends of the mounting bracket 31, which engage behind the locking of the second and the fourth bearing pin 21, 22 corresponding locking receptacles, for example, locking pin.
Die Lagerzapfen 13, 14, 21 , 22 des Lüftergehäuses 1 1 stellen eine lagegenaue Positionierung des Lüfterrades des Lüfters 5 in axialer und radialer Richtung zu einer an der Lagerschale 4 befindlichen Einlassdüse sicher. Die Schwingungsentkopplung ist am Lüftergehäuse 1 1 damit durch zwei Lagerachsen, mit jeweils gegenüberliegenden Lagerzapfen 13, 14 bzw. 21 , 22 gekennzeichnet. Auf die Lagerzapfen 13, 14, 21 , 22 ist beispielsweise jeweils ein beispielsweise ringförmiges Dämpfungselement 17 aufgesteckt. Das Dämpfungselement 17 ist beispielsweise aus Gummi hergestellt. Es erstreckt sich beispielsweise so radial um den jeweiligen Lagerzapfen, dass auch ein radialer Kontakt zwischen Lagerzapfen 13, 14, 21 , 22 und Verdampfer vermieden wird. Eine Übertragung von Schwingungen vom Lüfter 5 zum Verdampfer über die Lagerzapfen 13, 14, 21 , 22 wird dadurch vermieden. The journals 13, 14, 21, 22 of the fan housing 1 1 ensure a positionally accurate positioning of the fan wheel of the fan 5 in the axial and radial directions to an inlet nozzle located on the bearing 4 sure. The vibration decoupling is characterized on the fan housing 1 1 thus by two bearing axes, each with opposite bearing journals 13, 14 and 21, 22. On the bearing journals 13, 14, 21, 22, for example, in each case an example, annular damping element 17 is attached. The damping element 17 is made of rubber, for example. It extends, for example, so radially around the respective bearing journal, that even a radial contact between bearing pin 13, 14, 21, 22 and evaporator is avoided. A transmission of vibrations from the fan 5 to the evaporator via the bearing journals 13, 14, 21, 22 is thereby avoided.
Zur Montage des Lüftergehäuses 1 1 werden der erste und der dritte Lagerzapfen 13 und 14 des Lüftergehäuses 1 1 jeweils in entsprechende Aufnahmeausnehmung der Lagerschale, welche als Langlöcher gebildet sein können, eingeführt. Danach werden der zweite und der vierte Lagerzapfen 21 , 22 in entsprechende Aufnahmeausnehmungen der Lagerschale 4 durch Verschwenken des Lüftergehäuses 1 1 um eine durch den ersten Lagerzapfen 13 definierte Schwenkachse zur Lagerschale 4 hin eingeführt. Danach werden der zweite und der vierte Lagerzapfen 21 , 22 in den entsprechenden Aufnahmeausnehmungen durch das Arretierungselement 30 arretiert. Hierbei hintergreifen die Arretierungshaken 33 For mounting the fan housing 1 1, the first and the third bearing pin 13 and 14 of the fan housing 1 1 respectively in corresponding receiving recess of the bearing shell, which may be formed as slots introduced. Thereafter, the second and the fourth bearing pin 21, 22 inserted into corresponding receiving recesses of the bearing shell 4 by pivoting the fan housing 1 1 to a defined by the first bearing pin 13 pivot axis to the bearing shell 4 out. Thereafter, the second and the fourth bearing pin 21, 22 are locked in the corresponding receiving recesses by the locking element 30. Here, the locking hooks 33 engage behind
entsprechende Arretierungsaufnahmen, welche als Arretierungsbolzen ausgebildet sein können. corresponding locking receptacles, which may be formed as a locking pin.
Figur 2 zeigt eine schematische Darstellung des Lüfters 5 bei geöffnetem Befestigungsbügel 31 in Seitenansicht. Der Befestigungsbügel 31 ist wie dargestellt vom Lüfter 5 wegeschwenkt. Das Schwenken erfolgt dabei bei diesem Ausführungsbeispiel um die Schwenkachse des ersten Lagerzapfens 13. In der Ansicht von Figur 1 wird der Befestigungsbügel 31 dabei in die Bildebene hinein bzw. heraus geschwenkt. In Figur 2 ist an der linken Seite des Lüfters 5 eine Dichtung 37 zu erkennen, die zum Abdichten des Lüfters 5 mit einem Verdampfer dient. Arretierungshaken 33 sind seitlich am Befestigungsbügel 31 vorgesehen und dienen dazu, beim Schwenken des Befestigungsbügels 31 in Eingriff mit der Lagerschale 4 gebracht zu werden, um den Lüfter 5 zu befestigen. Figure 2 shows a schematic representation of the fan 5 with the mounting bracket 31 open in side view. The mounting bracket 31 is pivoted away from the fan 5 as shown. The pivoting takes place in this embodiment to the Pivot axis of the first journal 13. In the view of Figure 1, the mounting bracket 31 is thereby pivoted into the image plane in or out. In Figure 2, a seal 37 can be seen on the left side of the fan 5, which serves to seal the fan 5 with an evaporator. Arretierungshaken 33 are provided laterally on the mounting bracket 31 and serve to be brought when pivoting the mounting bracket 31 into engagement with the bearing shell 4 to secure the fan 5.
Gemäß einer Ausführungsform kann ein Federelement vorgesehen sein, dass den Befestigungsbügel 31 in seiner Schwenklage elastisch zum Verdampfer ausrichtet. Dadurch kann eine definierte Halterung des Lüftergehäuses 1 1 durch den Befestigungsbügel 31 erzielt werden. Der Befestigungsbügel 31 weist beispielsweise wenigstens einen Arretierungshaken 33 zum Verriegeln an einer dafür am Verdampfer vorgesehenen Arrentierungsaufnahme auf. Die Arrentierungsaufnahme kann als Arretierungsbolzen ausgebildet sein, der von dem Arretierungshaken 33 hintergreifbar sind. Bevorzugt ist der Arretierungshaken 33 so am Befestigungsbügel 31 ausgebildet, dass der Arretierungshaken 33 mit dem Befestigungsbügel 31 eine Einheit bildet. According to one embodiment, a spring element may be provided that aligns the mounting bracket 31 in its pivotal position elastically to the evaporator. As a result, a defined mounting of the fan housing 1 1 can be achieved by the mounting bracket 31. The mounting bracket 31 has, for example, at least one locking hook 33 for locking on a device provided on the evaporator Arrentierungsaufnahme. The arresting receptacle can be designed as a locking pin, which can be engaged behind by the locking hook 33. Preferably, the locking hook 33 is formed on the mounting bracket 31 so that the locking hook 33 forms a unit with the mounting bracket 31.
Das Arretierungselement 30 ist an den Lagerzapfen 21 , 22 des Lüftergehäuses 1 1 bevorzugt drehbar gelagert. Das Arretierungselement 30 wird beispielsweise an seinen seitlichen Enden mit jeweils einem Arretierungshaken 33 ausgeführt. Durch eine Drehbewegung des Arretierungselementes 30 um dessen Lagerachse werden die seitlichen Arretierungshaken 33 in die dafür vorgesehenen Arretierungsbolzen der Lagerschale 4 eingehängt und können sich dort abstützen. Dies erhöht die Stabilität der Verbindung des Lüftergehäuses 1 1 mit der Lagerschale 4. The locking element 30 is preferably rotatably mounted on the bearing journal 21, 22 of the fan housing 1 1. The locking element 30 is executed, for example, at its lateral ends, each with a locking hook 33. By a rotational movement of the locking element 30 about its bearing axis, the lateral locking hooks 33 are hooked into the designated locking bolts of the bearing shell 4 and can be supported there. This increases the stability of the connection of the fan housing 1 1 with the bearing shell. 4
Gemäß einer weiteren Ausführungsform ist am Arretierungselement 30 für eine Rastverbindung mit der Lagerschale 4 oder mit dem Verdampfer mindestens ein Rasthaken 35 angeordnet. Der Rasthaken 35 ist beispielsweise durch ein manuelles Auslenken aus der Verrastung lösbar. According to a further embodiment, at least one latching hook 35 is arranged on the locking element 30 for a latching connection with the bearing shell 4 or with the evaporator. The latching hook 35 is detachable, for example, by a manual deflection of the latching.
Zur Fixierung des Arretierungselementes 30 wird der am Arretierungselement 30 befindliche Rasthaken 35 in einer dafür vorgesehenen Aufnahme mit der Lagerschale 4 beispielsweise „hörbar" verrastet. Durch das hörbare Verrasten kann sichergestellt werden, dass der Bediener den Verrastungsvorgang besonders gut wahrnehmen kann. Die Geometrie des Rasthakens 35 ist beispielsweise so gewählt, dass beim Zusammendrücken von zwei einander gegenüber angeordneten Rasthaken 35 die Rastverbindung wieder lösbar ist, jedoch bei Belastung der geschlossenen Rastverbindung auf Zug die Rasthaken 35 noch weiter aufspreizen, um die Verrastung sicherzustellen. Gemäß einer Ausführungsform ist eine elastische Dichtung zwischen dem Lüftergehäuse 1 1 und der Lagerschale 4 vorgesehen. Die Dichtung ist beispielsweise verliersicher am Lüftergehäuse 1 1 angebracht, während sie lediglich dichtend an der Lagerschale 4 zum Anliegen kommt. Zur spaltfreien Anlage des Lüftergehäuses 1 1 an der Lagerschale 4 kann beispielsweise am vorderen umlaufenden Rand des Lüftergehäuses eine eingeknüpfte Dichtung vorgesehen sein, deren Geometrie so gewählt ist, dass der stabile Dichtungsfuß die verliersichere Befestigung am Lüftergehäuse sicherstellt, während die Dichtlippe flexibel und nahezu ohne Krafteinwirkung an der Lagerschale anliegt. Dadurch werden Fehlluft und somit Effizienzverlust durch Spalte und Körperschall durch teil- und zeitweise Anlage des Lüftergehäuses an der Lagerschale reduziert. In order to fix the locking element 30, the latching hook 35 located on the locking element 30 is latched "audibly" in a receptacle provided for this purpose with the bearing shell 4. The audible latching can ensure that the operator can perceive the latching process particularly well Latching hook 35 is, for example, chosen so that upon compression of two oppositely arranged latching hooks 35, the latching connection is releasable again, but on loading the closed latching connection on train the latching hooks 35 further spread to ensure the latching. According to one embodiment, an elastic seal between the fan housing 1 1 and the bearing shell 4 is provided. The seal is, for example, captively attached to the fan housing 1 1, while it only comes to rest sealingly on the bearing shell 4. For gap-free installation of the fan housing 1 1 on the bearing shell 4 may be provided, for example, at the front circumferential edge of the fan housing a knotted seal, the geometry is chosen so that the stable Dichtungsfuß secures the captive attachment to the fan housing, while the sealing lip flexible and almost no force rests against the bearing shell. As a result, incorrect air and thus efficiency loss due to gaps and structure-borne noise are reduced by partial and temporary contact of the fan housing with the bearing shell.
Figur 3 zeigt eine seitliche Ansicht einer Lagerschale 4, welche als Verdampferwanne eines Verdampfers 3 gebildet sein kann. Die Lagerschale 4 weist eine erste Aufnahmeausnehmung 15 und eine zweite Aufnahmeausnehmung 23 auf. Die Aufnahmeausnehmungen 15, 23 sind vorgesehen, die Lagerzapfen 13, 21 aufzunehmen. Für eine Befestigung am Lüfter 5 kommen die Lagerzapfen 13, 21 des Lüfters 5 in den Ausnehmungen 15, 23 zum Anliegen, so dass sie dort halt finden. Figur 4 zeigt eine schematische Darstellung des Verdampfers 3 mit daran angebrachtem Lüfter 5 bei geöffnetem Befestigungsbügel 31 in Seitenansicht. Dargestellt ist die Anordnung, bei der lediglich der erste Lagerzapfen 13 des Lüfters 5 in die entsprechende erste Aufnahmeausnehmung 15 der Lagerschale 4 eingreift. Der zweite Lagerzapfen 21 ist dabei noch beabstandet zu der ihm zugeordneten zweiten Ausnehmung 23 angeordnet. Die erste Aufnahmeausnehmung 15 ist in der Form eines Langlochs gebildet, so dass der eingefügte erste Lagerzapfen 13 sich gegen die Lagerschale 4 abstützen kann und den Lüfter 5 unten am Verdampfer 3 festhält. Dabei bleibt der Lüfter 5 um die Schwenkachse des ersten Lagerzapfens 13 herum schwenkbar. Beim weiteren Zusammenfügeprozess vom Lüfter 5 und der Lagerschale 4 kommt durch schwenken des Lüfters 5 um die Schwenkachse des ersten Lagerzapfens 13 herum der zweite Lagerzapfen 21 in der zweiten Ausnehmung 23 zum Anliegen. Wie in Figur 1 dargestellt wurde, sind in Figur 3 immer jeweils zwei Ausnehmungen 15 bzw. 23 hintereinander bzw. übereinander angeordnet, die dann von den jeweiligen Lagerzapfen 13, 21 eingegriffen werden. FIG. 3 shows a side view of a bearing shell 4, which may be formed as an evaporator trough of an evaporator 3. The bearing shell 4 has a first receiving recess 15 and a second receiving recess 23. The receiving recesses 15, 23 are provided to receive the bearing journals 13, 21. For mounting on the fan 5, the bearing pins 13, 21 of the fan 5 in the recesses 15, 23 come to rest, so that they find stop there. Figure 4 shows a schematic representation of the evaporator 3 with attached fan 5 with the mounting bracket 31 open in side view. Shown is the arrangement in which only the first bearing pin 13 of the fan 5 engages in the corresponding first receiving recess 15 of the bearing shell 4. The second bearing pin 21 is still spaced to the second recess 23 associated therewith. The first receiving recess 15 is formed in the shape of a slot, so that the inserted first bearing pin 13 can be supported against the bearing shell 4 and the fan 5 holds down the evaporator 3. In this case, the fan 5 remains pivotable about the pivot axis of the first journal 13. In the further assembly process of the fan 5 and the bearing shell 4 comes by pivoting the fan 5 about the pivot axis of the first bearing pin 13 around the second bearing pin 21 in the second recess 23 for concern. As has been shown in FIG. 1, two recesses 15 and 23 are always arranged one behind the other or one above the other in FIG. 3, which are then engaged by the respective bearing journals 13, 21.
Figur 5 zeigt eine schematische Darstellung des Verdampfers 3 mit daran angebrachtem Lüfter 5 bei geschlossenem Arretierungselement 30 in Seitenansicht. Dargestellt ist die Anordnung, bei der auch der zweite Lagerzapfen 21 des Lüfters 5 in die entsprechende zweite Aufnahmeausnehmung 23 des Lüfters 5 eingreift. Diese Anordnung entsteht durch weiteres Schwenken des Lüfters 5 um die Achse des ersten Lagerzapfens 13 auf die Lagerschale 4 bzw. den Verdampfer 3 zu. Der Befestigungsbügel 31 ist hierbei nun geschlossen, und übernimmt die Funktion, den Verdampfer 3 und den Lüfter 5 in Position zu halten. Figure 5 shows a schematic representation of the evaporator 3 with attached fan 5 with the locking element 30 closed in side view. Shown is the arrangement in which the second bearing pin 21 of the fan 5 engages in the corresponding second receiving recess 23 of the fan 5. This arrangement is created by further pivoting of the fan 5 about the axis of the first journal 13 on the bearing shell 4 and the evaporator 3 to. The mounting bracket 31 is in this case now closed, and takes over the function to keep the evaporator 3 and the fan 5 in position.
Am Befestigungsbügel 31 ist ferner ein Arretierungshaken 33 vorgesehen, der in einer an der Lagerschale 4 vorgesehenen Arretierungsaufhahme 34 hintergreifen kann. Bei diesem Ausführungsbeispiel ist die Arretierungsaufhahme 34 als Arretierungsbolzen ausgeführt, der von der Lagerschale 4 absteht. Beim Schwenken des Lüfters 5 um den ersten Lagerzapfen 13 herum kommt der Arretierungshaken 33 an dem Arretierungsbolzen zum Anliegen und hebelt den Lüfter 5 unten gegen den Verdampfer 3. Durch die Hebelübersetzung wird ein Anpresssen des Lüfters 5 an die Lagerschale 4 erreicht. Dadurch wird auch mittels der Dichtung 37 eine besonders gute Abdichtung zwischen Verdampfer 3 und Lüfter 5 bei geringen Betätigungskräften ermöglicht. On the mounting bracket 31, a locking hook 33 is also provided, which can engage behind in a provided on the bearing shell 4 Arretierungsaufhahme 34. In this embodiment, the Arretierungsaufhahme 34 is designed as a locking pin that protrudes from the bearing shell 4. When pivoting the fan 5 to the first pivot pin 13 around the Arretierungshaken 33 comes to rest on the locking pin and lever the fan 5 below against the evaporator 3. By the lever transmission, a pressing of the fan 5 is achieved at the bearing shell 4. As a result, by means of the seal 37, a particularly good seal between the evaporator 3 and the fan 5 is made possible at low actuating forces.
Figur 6 zeigt eine schematische Darstellung eines Befestigungsbügels 31 mit dem Rasthaken 35. Der Rasthaken 35 ist mit dem Verdampfer 3 bzw. mit der Lagerschale 4 verrastbar und vermeidet ein versehentliches Lösen des Befestigungsbügels 31 . Zur Fixierung des Befestigungsbügels 31 in seiner Endlage wird der am Befestigungsbügel 31 befindliche Rasthaken 35 in einer dafür vorgesehenen Aufnahme der Lagerschale verrastet. Figure 6 shows a schematic representation of a mounting bracket 31 with the latching hook 35. The latching hook 35 can be latched to the evaporator 3 and the bearing shell 4 and avoids accidental release of the mounting bracket 31st To fix the mounting bracket 31 in its end position located on the mounting bracket 31 latch hook 35 is locked in a designated receptacle of the bearing shell.
