Description

Die Erfindung betrifft ein Verfahren zum Einbauen eines Motorkompressors in eine Nische eines Kühlgerätes, sowie ein Kühlgerät mit Mittel zur Durchführung dieses Verfahrens.The invention relates to a method for installing a motor compressor in a niche of a cooling device, and a cooling device with means for performing this method.

Bei einem bekannten Kühlgerät (US-A-2 743 891) wird beim Einbau des Motorkompressors in der Weise verfahren, daß der Motorkompressor in einer Schublade angeordnet wird, die in stabilen seitlichen, U-förmigen Schienen in einer Nische des Kühlgerätes angeordnet ist. Diese sich gegenüberliegenden, U-förmigen Schienen verhindern beim Herausziehen des darin geführten Schubes aus der Nische, daß bei einem Übergewicht des herausgezogen Teils des Schubes derselbe nicht nach unten wegkippt. Diese U-förmigen Schienen und der als Halteplatte für den Motorkompressor dienende Schub mit seinen in die Schienen eingreifenden, angepaßten Führungsleisten erfordern einen erheblichen technischen Aufwand. Dabei müssen die Schienen und die Führungsleisten so stabil ausgebildet sein, daß sie bei teilweise herausgezogenem Schub die dabei auftretenden Knickkräfte aufnehmen können. Zudem verbleibt bei diesem Aufbau der gesamte Schub auch bei eingebautem Motorkompressor in der Nische.In a known cooling device (US-A-2 743 891) the motor compressor is installed in such a way that the motor compressor is arranged in a drawer which is arranged in stable side, U-shaped rails in a niche of the cooling device. These opposing, U-shaped rails prevent the drawer guided therein from being pulled out of the niche, so that if the part of the drawer that is pulled out is overweight, it does not tip down. These U-shaped rails and the thrust serving as a holding plate for the motor compressor with its adapted guide rails engaging in the rails require considerable technical effort. The rails and the guide strips must be so stable that they can absorb the buckling forces that occur when the thrust is partially pulled out. With this design, the entire thrust remains in the niche even when the motor compressor is installed.

Bei einem weiteren bekannten Kühlgerät (US-A-2 637 178) befinden sich in einer Nische waagrecht verlauende Winkelschienen als Führungen für eine Halteplatte, auf welcher ein Motorkompressor festgesetzt ist. Die Halteplatte greift in ihrer in die Nische eingebauten Lage unter einen gehäusefesten Vorsprung, während ihr der Öffnungsseite der Nische zugewandtes Ende am Gehäuse des Kühlgerätes festgespannt ist. Soll bei diesem Aufbau der Motorkompressors montiert werden, dann muß die Halteplatte aus der Nische des Kühlgerätes zumindest weitgehend herausgezogen sein. Dann steht die Halteplatte jedoch nicht mehr in Eingriff mit dem gehäusefesten Vorsprung, so daß sie durch das Gewicht, des außerhalb der Nische aufgesetzten Motorkompressors nach unten wegkippt. Die Halteplatte muß daher während der Montage des Motors, insbesondere bei der Verbindung seiner Kältemittelleitungen mit den Kältemittelleitungen des Kältemittelkreislaufs durch äußere Stützen gehalten werden. Dabei müssen diese Stützen bei der Montage an einem Fließband von jeder Arbeitsstation zur nächsten mittransportiert werden, wenn sich der Einbau des Motorkompressors nicht an einem Arbeitsplatz ausführen läßt. Auch bei diesem Aufbau und der daraus folgenden Verfahrensweise verbleibt die Halteplatte bei eingebauten Motorkompressor in der Nische.In another known cooling device (US-A-2 637 178) there are horizontally extending angle rails in a niche as guides for a holding plate on which a motor compressor is fixed. The holding plate engages in its position in the recess under a housing-fixed projection, while its end facing the opening side of the recess is clamped to the housing of the cooling device. If the motor compressor is to be mounted in this construction, then the holding plate must be at least largely pulled out of the niche of the cooling device. Then the holding plate is no longer in engagement with the housing-fixed projection, so that it tilts downward due to the weight of the motor compressor placed outside the niche. The holding plate must therefore be held by external supports during the assembly of the engine, especially when connecting its refrigerant lines to the refrigerant lines of the refrigerant circuit. These supports must be transported from each workstation to the next when they are assembled on an assembly line if the installation of the motor compressor cannot be carried out at one workstation. With this construction and the resulting procedure, the holding plate remains in the niche when the motor compressor is installed.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen zu treffen, durch die ein verminderter Aufwand für den Einbau des Motorkompressors in die Nische des Gerätes erforderlich ist.The invention has for its object to take measures by which a reduced effort for the installation of the motor compressor in the niche of the device is required.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die im Schutzbegehren angebenenen Maßnahmen.This object is achieved according to the invention by the measures specified in the request for protection.

Bei einem Einbau eines Motorkompressors in der durch die Erfindung angegebenen Weise können die Verbindungen der Anschlüsse des Kompressors mit den von außen herangeführten Leitungen außerhalb der Nische vorgenommen werden, so daß ein freier Zugang zu den Lötstellen gegeben ist. Der Motorkompressors braucht danach lediglich in die Nische eingeschoben und darin festgesetzt zu werden. Hierzu kann zwischen dem Motorkompressor und dem rückwärtigen Teil der Nische eine mechanische Steckverbindung vorgesehen werden, so daß Arbeiten innerhalb der Nische für das Festlegen nicht erforderlich sind. Die Befestigung im vorderen Teil der Nische kann dann insbesondere am Öffnungsrand in einfacher Weise mittels Schrauben erfolgen. Um den Motorkompressor in einfacher Weise im Bereich vor der Nische arbeitsgerecht bereitstellen zu können, ist im Bereich des Bodens der Nische eine Halteplatte festgesetzt, die über die Öffnungsebene der Nische vorsteht. Auf den vorstehenden Teil wird zumindest teilweise der Motorkompressor aufgesetze, so daß seine Anschlüsse unbehindert zugänglich sind. Dabei ist der Motorkompressor nur lose auf die Halteplatte aufgesetzt und kann daher auf der Halteplatte nach dem Verlöten der Anschlüsse in die endgültige Position innerhalb der Nische eingeschoben werden. Die Halteplatte ist dagegen lösbar in die Nische eingesetzt und wird vor dem Festsetzen des Motorkompressors herausgezogen. Sie steht dann für weitere Montagevorgänge zur VerfügungWhen installing a motor compressor in the manner specified by the invention, the connections of the compressor connections can be made outside the niche with the lines leading from the outside, so that there is free access to the soldering points. The motor compressor then only needs to be pushed into the niche and fixed in it. For this purpose, a mechanical plug connection can be provided between the motor compressor and the rear part of the niche, so that work within the niche is not necessary for fixing. The attachment in the front part of the niche can then be carried out in a simple manner, in particular at the opening edge, by means of screws. In order to be able to provide the motor compressor in a simple manner in the area in front of the niche, a holding plate is fixed in the area of the bottom of the niche, which protrudes beyond the opening level of the niche. The motor compressor is at least partially placed on the above part, so that its connections are freely accessible. The motor compressor is only loosely placed on the holding plate and can therefore be pushed into the final position within the niche after the connections have been soldered. The holding plate, on the other hand, is detachably inserted in the niche and is pulled out before the motor compressor is fixed. It is then available for further assembly processes

Vorteilhafte Ausgestaltungen sind in den weiteren Ansprüchen angegeben.Advantageous refinements are specified in the further claims.

Die Erfindung ist nachfolgend an Hand der Zeichnungen eines Ausführungsbeispiel näher erläutert.The invention is explained below with reference to the drawings of an embodiment.

Es zeigen:

  • Fig. 1 eine Arbeitsgerätschaft für den Einbau eines Motorkompressors in eine Nische,
  • Fig. 2 die Zuordnung einer Halteplatte zu Aufnahmen in der Nische und
  • Fig. 3 eine Schiene für die Halterung des Kompressors.
Show it:
  • 1 is a work tool for installing a motor compressor in a niche,
  • Fig. 2 shows the assignment of a holding plate to recordings in the niche and
  • Fig. 3 is a rail for holding the compressor.

In der Rückseite eines nur teilweise dargestellten Gehäuses 1 eines Kühlgerätes, insbesondere eines Haushaltkühl- und/oder Gefriergerätes ist eine Nische 2 für die Unterbringung eines Motorkompressors 3 vorgesehen. Auf dem Boden 4 der Nische 2 liegt eine Halteplatte 5 auf, die in der Nische 2 lösbar festgesetzt ist. Die Halteplatte 5 ragt über die Öffnungsebene der Nische 2 nach außen, wobei auf den nach außen ragenden Teil der Halteplatte der Motorkompressor 3 zumindest teilweise aufgesetzt ist. Die durch sein Gehäuse herausgeführten Anschlüsse 8 können daher ohne Beengung durch die Wände der Nische 2 mit Kältemittelleitungen 7 verbunden werden, die dem Kältemittelkreislauf des Kühlgeräten zugehören. An der Unterseite des Motorkompressors 3 sind zwei parallel zueinander verlaufende Schienen 8 festgesetzt, die im Querschnitt U-förmig mit senkrecht abgewinkelten Schenkelenden 9 ausgebildet sind. Die abgewinkelten Schenkelenden liegen auf den in die Tiefe der Nische 2 laufenden Längskanten 10 der Halteplatte 5 lose auf. Nach der Verbindung der Anschlüsse 6 mit den Kältemittelleitungen 7 und gegebenenfalls anderer auszuführender Arbeiten, wie die Herstellung der elektrischen Anschlüsse, kann dann der Kompressor unter entsprechender Verformung der Kältemittelleitungen 7 auf der feststehenden Halteplatte 5 durch den gleitenden Eingriff der Schenkelenden 9 mit den Längskanten 10 in die Nische 2 eingeschoben werden.In the back of a housing 1 of a refrigerator, only a household refrigerator and / or freezer, only partially shown, a niche 2 is provided for accommodating a motor compressor 3. On the bottom 4 of the niche 2 there is a holding plate 5 which is detachably fixed in the niche 2. The holding plate 5 projects outward beyond the opening level of the recess 2, the motor compressor 3 being at least partially placed on the outwardly projecting part of the holding plate. The connections 8 led out through its housing can therefore be connected without restriction through the walls of the recess 2 with refrigerant lines 7, which are the refrigerant circuit of the cooling devices To belong. On the underside of the motor compressor 3, two rails 8 running parallel to each other are fixed, which are U-shaped in cross section with vertically angled leg ends 9. The angled leg ends lie loosely on the longitudinal edges 10 of the holding plate 5 which run into the depth of the recess 2. After the connections 6 have been connected to the refrigerant lines 7 and, if necessary, other work to be carried out, such as the production of the electrical connections, the compressor can then deform the refrigerant lines 7 accordingly on the fixed holding plate 5 by the sliding engagement of the leg ends 9 with the longitudinal edges 10 in the niche 2 can be inserted.

Bei in die Nische 2 eingesetzter Halteplatte 5 greift das in der Nische 2 liegende Ende 11 der Halteplatte 5 in eine waagerecht verlaufende Steckaufnahme, die als eine in die Rückwand 12 der Nische 2 eingeformte Tasche 13 ausgebildet ist. Die Halteplatte 5 kann daher auch bei Belastung ihres den Öffnungsrand 14 der Nische 2 überragenden Teils durch den Kompressor oder andere Kräfte nicht nach unten wegkippen. Die Steckaufnahme kann jedoch auch durch Tatzen 15 gebildet werden, die an der Rückwand 12 mit Abstand über dem Boden 4 angeordnet sind. Die Tatzen 15 reichen jedoch in jedem Fall seitlich über die Längskanten 10 hinaus, so daß zur Rückwand 12 gerichtete Enden 16 der Schienen 8 Platz finden. Die so ausgebildeten Steckaufnahmen für die Schienen 16 im rückwärtigen Teil der Nische 2 erfordern bei eingeschobenen Kompressor somit keine zusätzlichen Befestigungsmittel. Es genügt dann an dem der Öffnung der Nische 2 zugewandten Ende der Schienen 8 jeweils eine nach unten abgekantete Lasche 17, welche vor den Öffnungsrand 14 greift und damit verschraubt werden kann. Die Enden 16 weisen dabei im übrigen eine dem Abstand zwischen dem Boden 4 und den Tatzen 15 angepaßte Stärke auf und sind vorzugsweise gegen seitliches Verschieben durch einen entsprechenden Formschluß gesichert. Zum Festschrauben der Schienen 8 sind dabei Bohrungen 18 im Öffnungsrand 14 vorgesehen.When the holding plate 5 is inserted into the recess 2, the end 11 of the holding plate 5 lying in the recess 2 engages in a horizontally extending plug-in receptacle which is designed as a pocket 13 molded into the rear wall 12 of the recess 2. The holding plate 5 can therefore not tip downwards even when its part projecting beyond the opening edge 14 of the niche 2 is loaded by the compressor or other forces. However, the plug receptacle can also be formed by paws 15, which are arranged on the rear wall 12 at a distance above the floor 4. However, the paws 15 in any case extend laterally beyond the longitudinal edges 10, so that ends 16 of the rails 8 directed towards the rear wall 12 can be accommodated. The plug receptacles designed in this way for the rails 16 in the rear part of the recess 2 therefore do not require any additional fastening means when the compressor is inserted. It is then sufficient at the end of the rails 8 facing the opening of the recess 2 in each case a tab 17 bent downwards which engages in front of the opening edge 14 and can thus be screwed together. The ends 16 have a thickness adapted to the distance between the floor 4 and the paws 15 and are preferably secured against lateral displacement by a corresponding positive engagement. For screwing the rails 8, holes 18 are provided in the opening edge 14.

Auf dem Boden 4 der Nische 2 ist zwischen den Steckaufnahmen 13, 15 und dem Öffnungsrand 14 der Nische 2 ein Raststeg 19 vorgesehen, für den in der Halteplatte 5 eine entsprechend angepaßte Rastnut 20 vorgesehen ist. Bei in die Nische 2 eingesetzten Halteplatte kommt diese Steckverbindung 19, in Eingriff und sichert die Halteplatte gegen versehentliches Lösen aus der Steckaufnahme 13, 15. Nach dem Einschieben des Motorkompressors 3 wird die Halteplatte 5 soweit angehoben, daß die Rastverbindung 19, 20 gelöst wird und die Halteplatte 5 nach außen gezogen werden kann. Danach kann die Lasche 17 mit dem Rand 14 beispielsweise verschraubt werden.On the bottom 4 of the niche 2 between the plug-in receptacles 13, 15 and the opening edge 14 of the niche 2, a locking web 19 is provided, for which a correspondingly adapted locking groove 20 is provided in the holding plate 5. When inserted into the niche 2, this connector 19 comes into engagement and secures the retaining plate against accidental loosening from the plug receptacle 13, 15. After inserting the motor compressor 3, the holding plate 5 is raised so far that the latching connection 19, 20 is released and the holding plate 5 can be pulled outwards. The tab 17 can then be screwed to the edge 14, for example.

Um den lose auf die Halteplatte 5 aufgesetzten Motorkompressor gegen Abrutschen zu sichern, aber auch, um ihn in die richtige Position zu stellen, die der Länge der Kälteleitungen 6 entspricht, wobei die Länge der Kälteleitungen 6 ursächlich von deren zu erzielenden Endlage bestimmt wird, ist die Halteplatte 5 an ihrem aus der Nische 2 herausragenden Ende mit Anschlagkanten 21 versehen, an welchen die Stirnseiten der Schienen 8 in der Montagestellung anschlagen. Die Schienen 8 sind im Querschnitt symmetrisch ausgebildet, um mit einer Ausführung beide Schienen realisieren zu können. Dabei ist der Raum zwischen den Schenkeln der Schienen 8 für die Anordnung von Schwingungsdämpfungselementen 22 ausgenutzt, auf weichen Befestigungsfüße 23 des Kompressors 3 festgesetzt sindIn order to secure the motor compressor loosely placed on the holding plate 5 against slipping, but also to place it in the correct position, which corresponds to the length of the cooling lines 6, the length of the cooling lines 6 being determined by the end position to be achieved the retaining plate 5 at its end protruding from the niche 2 is provided with stop edges 21, against which the end faces of the rails 8 strike in the assembly position. The rails 8 are symmetrical in cross section in order to be able to implement both rails with one embodiment. The space between the legs of the rails 8 is used for the arrangement of vibration damping elements 22, on which soft fastening feet 23 of the compressor 3 are fixed
