The interior (2) of a refrigeration appliance has two carriers (4) with openings (5) on one side of the liner which support the injection moulded fan and motor cage (1) by means of integrally moulded hooks (3) passing through the liner wall in line with the motor support band (10).

Description

Die Erfindung betrifft ein Kältegerät nach dem Oberbegriff von Anspruch 1.The invention relates to a refrigerator according to the preamble of claim 1.

Im Inneren von Kältegeräten wie Kühlschränken oder Gefriergeräten sind häufig Gebläse zum Verteilen der kalten Luft vom Verdampfer über den Innenraum des Kältegeräts angeordnet. Die Motoren der Gebläse müssen sicher am Kältegerät befestigt werden. Um verschiedene zur Verwendung kommende Motortypen an unterschiedliche Kältegerättypen anzupassen, sind diese über speziell angepasste Aufnahmen, die gewissermaßen als Befestigungsadapter dienen und kostengünstig als Kunststoffkäfige ausgeführt sein können, an dafür vorgesehene Träger an dem Inneren der Gehäuse der Kältegeräte gehaltert. Um eine einfache Montage der in Kunststoffkäfigen gehalterten Motoren in dem Träger zu gewährleisten sind für die Verbindung von Kunststoffkäfig und Trägern häufig Rastverbindungen vorgesehen. Dabei rastet der im Kunststoffkäfig gehalterte Motor beim Einführen in den Träger von innen in dafür vorgesehene Ausnehmungen am Träger ein. Die Träger sind üblicherweise beidseitig des Motors angeordnet und aus Kostengründen häufig ebenfalls aus Kunststoff hergestellt. Aufgrund des Drucks den der Motor beim Einführen und im Betrieb von innen auf den Träger ausübt und des insbesondere im Betrieb herrschenden Temperaturunterschieds, der durch den sich erwärmenden Motor im Innern der Kältegerätumgebung bedingt ist, kann es dazu kommen, dass der Motor die Tragflächen der Träger von sich weg verbiegt. Der Träger wird dabei sozusagen aufgebogen und bleibt, aufgrund seiner Kunststoffausführung, in dieser Position. Hierdurch kann es geschehen, dass sich die Rastverbindungen zwischen dem Motor bzw. dem den Motor halternden Kunststoffkäfig und dem Träger gelöst werden und der Motor aus dem Träger fällt, was zu erheblichen Beschädigungen am Kältegerät führen kann.In the interior of refrigerators such as refrigerators or freezers fans are often arranged for distributing the cold air from the evaporator on the interior of the refrigerator. The motors of the fans must be securely fastened to the refrigeration unit. In order to adapt different types of motors to be used for different types of refrigerators, they are supported on specially designed receptacles, which in a sense serve as fastening adapters and can be cost-effective as plastic cages, on the inside of the housing of the refrigeration appliances. In order to ensure easy mounting of the content in plastic cages held motors in the carrier locking connections are often provided for the connection of plastic cage and carriers. In this case, the motor held in the plastic cage snaps when inserted into the carrier from the inside into recesses provided on the carrier. The carriers are usually arranged on both sides of the engine and often also made of plastic for cost reasons. Due to the pressure exerted by the motor from the inside to the carrier during insertion and operation and the temperature difference prevailing in operation, which is caused by the warming engine inside the refrigerator environment, it may happen that the motor, the wings of the carrier bends away. The carrier is bent as it were and remains, due to its plastic design, in this position. This can happen that the latching connections between the engine or the engine-holding plastic cage and the carrier are released and the engine falls out of the carrier, which can lead to significant damage to the refrigerator.

Der Erfindung liegt die Aufgabe zugrunde, ein Kältegerät mit einem, über einen Kunststoffkäfig mit einem Träger in seinem Inneren gehalterten Motor so auszugestalten, dass der Motor sicher befestigt ist und dennoch einfach montierbar bleibt.The invention has for its object to design a refrigeration device with a content, held on a plastic cage with a carrier in its interior motor so that the engine is securely attached and yet easy to install.

Gelöst wird die Aufgabe gemäß der Erfindung durch ein Kältegerät mit den Merkmalen von Anspruch 1.The object is achieved according to the invention by a refrigeration device with the features of claim 1.

Erfindungsgemäß ist der das Gebläse bzw. den Motor des Gebläses halternde, speziell an das Gebläse angepasste, Kunststoffkäfig beidseitig mit Rasthaken ausgestattet, welche von der dem Kunststoffkäfig gegenüberliegenden Seite in Ausnehmungen eingreifen, die Bestandteil von Trägerelementen sind, welche den Kunststoffkäfig seitlich einfassen. Die Rastverbindung zu den Trägerelementen wird also nicht motorseitig hergestellt, vielmehr greifen die Rasthaken jeweils von der außerhalb des Motors liegenden Seite in die Ausnehmungen der Trägerelemente ein. Dadurch werden die Trägerelemente gewissermaßen zwischen dem Kunststoffkäfig selbst und den an dem Kunststoffkäfig angeformten als Gegenlager vorgesehenen Rasthaken eingeklemmt. Der Körper des Kunststoffkäfigs und die Rasthaken fixieren die Träger also jeweils zwischen sich und drücken von beiden Seiten auf den Träger, wobei die Rasthaken in die Ausnehmungen der Träger eingreifen, so dass eine stabile Rastverbindung entsteht, die Träger können nicht mehr von dem Kunststoffkäfig weg nach außen gedrückt werden, zumindest würde im Falle des Wegdrückens der Träger die Verbindung über die Rasthaken noch stabiler, da die Rasthaken in diesem Falle noch stärker an die Träger bzw. in die Ausnehmungen gedrückt würden. Damit werden einfach montierbare Rastverbindungen beibehalten, die jedoch gewissermaßen beidseitig am Träger eingreifen, den Träger festklemmen und dadurch trotz der in Kältegeräten herrschenden Temperaturbelastungen eine stabile Halterung des Gebläses gewährleistet.According to the invention, the plastic cage supporting the blower or the motor of the blower, specially adapted to the blower, is provided on both sides with latching hooks which engage in recesses in the recesses opposite the plastic cage, which are part of support elements which laterally surround the plastic cage. The latching connection to the support elements is therefore not made on the motor side, but rather engage the latching hooks each of the lying outside the motor side in the recesses of the support elements. As a result, the support elements are effectively clamped between the plastic cage itself and the molded on the plastic cage provided as an abutment locking hooks. The body of the plastic cage and the latching hooks thus fix the carrier in each case between them and press on both sides of the carrier, wherein the latching hooks engage in the recesses of the carrier, so that a stable latching connection is formed, the carrier can not move away from the plastic cage be pressed outside, at least in the case of pushing away the carrier, the connection via the locking hooks more stable, since the locking hooks would be pressed even stronger in this case to the carrier or in the recesses. This easily retainable snap-in connections are maintained, but to some extent engage on both sides of the carrier, clamp the carrier and thereby ensures a stable mounting of the fan despite the prevailing in refrigerators temperature loads.

Die Ausnehmungen in den Trägern sind vorzugsweise als rechteckige Schlitze ausgebildet, so dass die Haken eine möglichst große Angriffsfläche zum Einrasten vorfinden. Dadurch wird die Stabilität der Verbindung optimiert.The recesses in the carriers are preferably formed as rectangular slots, so that the hooks find the largest possible engagement surface for snapping. This optimizes the stability of the connection.

Die Haken sind so am Kunststoffkäfig angeordnet, dass sie von der Seite aus auf den Träger zugreifen, ihn umschließen und in die Ausnehmungen des Trägers eingreifen, von der aus der Kunststoffkäfig in den Träger eingeführt wird. Dadurch wird genau der Bereich, der beim Einführen des Kunststoffkäfigs in den Träger der größten Belastung ausgesetzt ist, beim Fixieren der Rastverbindung an den Kunststoffkäfig herangezogen. Hierdurch kann die beste Stabilität der Rastverbindung erreicht werden.The hooks are arranged on the plastic cage, that they access from the side of the carrier, enclose it and engage in the recesses of the carrier, from which the plastic cage is inserted into the carrier. This will be exactly the area which is exposed during insertion of the plastic cage in the carrier of the largest load, used in fixing the locking connection to the plastic cage. As a result, the best stability of the latching connection can be achieved.

In einer bevorzugten Ausführungsform sind die Haken beabstandet um die Vorderkante der Träger, die sich in dem vorab beschriebenen Einführbereich des Kunststoffkäfigs befindet, herumgeführt und liegen damit nur in dem Bereich direkt am Träger an, in dem sie in die Ausnehmungen einrasten. Dadurch entsteht zwischen dem jeweiligen Trägerelement und dem eingreifenden Haken außerhalb der Ausnehmungen ein Sicherheitsabstand, in den der Träger, falls er beim Einführen des Motors leicht verbogen wird, eindringen kann, ohne dabei gleich am Haken selbst anzugreifen. Dies ist eine weitere Absicherung dagegen dass die Träger, falls sie leicht nach außen gedrückt werden, die Rastverbindung durch ein Wegdrücken der Rasthaken öffnen. Auch hierdurch wird die Sicherheit der Rastverbindung weiter erhöht.In a preferred embodiment, the hooks are guided around the front edge of the carrier, which is located in the above-described insertion region of the plastic cage, and thus lie directly in the region directly on the carrier, in which they engage in the recesses. This creates between the respective support member and the engaging hook outside of the recesses a safety distance, in which the carrier, if it is slightly bent during insertion of the motor, can penetrate without directly attacking the hook itself. This is a further safeguard, however, that the carrier, if they are pressed slightly outward, open the latching connection by pushing away the latching hook. This also further increases the safety of the locking connection.

Der Körper des Kunststoffkäfigs selbst, welcher zwischen die beiden Träger eingesetzt wird, weist vorzugsweise einen geschlossenen Rahmen auf. Durch diesen wird ein gewisser Druck von der Innenseite auf die Träger ausgeübt, welcher den Gegenspieler für die als Gegenlager von außen eingreifenden Rasthaken darstellt. Die Träger werden somit zwischen dem geschlossenen Rahmen und den Haken fixiert.The body of the plastic cage itself, which is inserted between the two carriers, preferably has a closed frame. By this a certain pressure is exerted on the carrier from the inside, which represents the opponent for engaging as an abutment from the outside locking hooks. The carriers are thus fixed between the closed frame and the hooks.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den Unteransprüchen im Zusammenhang mit der Beschreibung eines Ausführungsbeispiels, das anhand der Zeichnung eingehend erläutert wird.Further details and advantages of the invention will become apparent from the subclaims in connection with the description of an embodiment which is explained in detail with reference to the drawing.

Der Kunststoffkäfig 1 dient der Halterung eines hier nicht gezeigten Gebläses, welches Kühlluft in den Innenraum eines Kältegeräts, insbesondere eines Kühlschranks bläst. An der Frontseite des Kunststoffkäfigs 1 befindet sich die Stütze 10 für die Lüfterwelle des Gebläses.It shows:

Fig. 2
a detail section through the plastic cage of FIG. 1.
The plastic cage 1 serves to hold a blower, not shown here, which Cooling air blows into the interior of a refrigerator, in particular a refrigerator. At the front of the plastic cage 1 is the support 10 for the fan shaft of the blower.

Im Innenraum 2 des Kühlschranks sind zwei Träger 4 angebracht, die rechteckige Ausnehmungen 5 aufweisen. Die Träger 4 sind zueinander mit einem Abstand an der Wand des Innenraums 2 befestigt, der in etwa dem Außendurchmesser des Kunststoffkäfigs 1 entspricht.In the interior 2 of the refrigerator, two carriers 4 are mounted, which have rectangular recesses 5. The carriers 4 are attached to each other at a distance to the wall of the inner space 2, which corresponds approximately to the outer diameter of the plastic cage 1.

Im unteren Bereich besteht der Kunststoffkäfig 1 aus einem geschlossenen Ring 6. Dieser geschlossene Ring 6 weist auf jeder Seite einen Stützbereich 9 auf, der an der Innenseite des Trägers anliegt und verhindert, dass der Träger durch den Druck des Hakens 3 nach innen ausweichen kann. Der Haken 3 ist in 3 Teile untergliedert. Mit dem Schenkel 3a, der in etwa senkrecht von dem Kunststoffkäfig 1 absteht, ist der Haken an diesem befestigt. Der Schenkel 3b verläuft in etwa parallel zu dem geschlossenen Ring 6 des Kunststoffkäfigs 1 und dient zusammen mit dem Schenkel 3a dazu, den Haken um den Träger 4 herumzuführen, so dass die Hakenspitze 3c von der Außenseite in die Ausnehmung 5 des Trägers 4 einrasten kann. Auch liegt die Elastizität des Hakens hauptsächlich in dem Schenkel 3b begründet.In the lower part, the plastic cage 1 consists of a closed ring 6. This closed ring 6 has on each side a support portion 9 which bears against the inside of the carrier and prevents the carrier can escape by the pressure of the hook 3 inwards. The hook 3 is divided into 3 parts. With the leg 3a, which projects approximately perpendicularly from the plastic cage 1, the hook is attached to this. The leg 3b extends approximately parallel to the closed ring 6 of the plastic cage 1 and, together with the leg 3a, serves to guide the hook around the carrier 4 so that the hook tip 3c can engage in the recess 5 of the carrier 4 from the outside. Also, the elasticity of the hook is mainly due to the leg 3b.

Beim Aufschieben des Kunststoffkäfigs 1 gleitet zuerst die Hakenspitze 3c auf dem vorderen Teil des Trägers 4. Sobald der Kunststoffkäfig 1 in der richtigen Position ist, rastet die Hakenspitze 3c in die Ausnehmung 5 des Trägers 4 ein und verhindert so, dass der Kunststoffkäfig 1 wieder abgezogen werden kann. Während des Aufschiebens wird der Träger 4 durch die untere Doppelführung 7, die obere Führung 8 sowie dem Haken 3 an der Außenseite und dem Stützbereich 9 des geschlossenen Rings 6 an der Innenseite geführt.When pushing the plastic cage 1, first the hook tip 3c slides on the front part of the carrier 4. As soon as the plastic cage 1 is in the correct position, the hook tip 3c snaps into the recess 5 of the carrier 4 and prevents the plastic cage 1 from being pulled off again can be. During the sliding of the support 4 is guided by the lower double guide 7, the upper guide 8 and the hook 3 on the outside and the support portion 9 of the closed ring 6 on the inside.

Durch größere Temperaturunterschiede zwischen der Außen- und der Innenseite des Kunststoffkäfigs 1 kann es zu gewissen Verformungen kommen. Doch selbst wenn sich der geschlossene Ring 6 ausdehnt und dabei mit den Stützbereichen 9 die Träger 4 nach außen drückt, wird die Verrastung nicht gelöst, da der Träger 4 dem Haken 3 entgegengedrückt wird. Auf den Haken 3 wirkt zu keinem Zeitpunkt eine Kraft, die ihn aus der Ausnehmung 5 herausdrücken würde.Larger temperature differences between the outside and the inside of the plastic cage 1 can lead to certain deformations. But even if the closed ring 6 expands and presses with the support portions 9, the carrier 4 to the outside, the latching is not solved, since the carrier 4 is pressed against the hook 3. At no time acts on the hook 3, a force that would push him out of the recess 5.

Durch die erfindungsgemäße Konstruktion ist daher gewährleistet, dass sich der Kunststoffkäfig 1 auch bei größeren Temperaturunterschieden, die durch einen heißen Gebläsemotor in seinem Inneren und die vorbeistreichende Kühlluft an seinem Äußeren nicht aus seiner Verrasterung lösen kann. Auch durch das Gebläse bedingte Schwingungen können die Verrasterung des Kunststoffkäfigs 1 nicht lösen und den Haken 3 aus der Ausnehmung 5 drücken.The construction according to the invention therefore ensures that the plastic cage 1 can not be released from its latching even with larger temperature differences, which can not be removed from its exterior by a hot blower motor in its interior and the passing cooling air on its exterior. Also caused by the fan vibrations can not solve the Verrasterung the plastic cage 1 and press the hook 3 from the recess 5.
