Description

Kältegerät The refrigerator
Die Erfindung betrifft ein Kältegerät nach dem Oberbegriff von Anspruch 1.The invention relates to a refrigerator according to the preamble of claim 1.
Kältegeräte bestehen in der Regel aus einer Außenschale und einer Innenschale, die einen Innenraum umgibt. Die Außenschale weist einen Boden, einen Deckel, zwei Seitenteile und eine Rückwand auf. Das Innengehäuse ist in der Regel aus einem thermoplastischen Kunststoff gefertigt und tiefgezogen. Die Außenabmessungen der Innenschale sind kleiner als die Innenabmessungen der Außenschale. Die beiden Schalen sind so dimensioniert, dass zwischen den Schalen bei der Montage ein Hohlraum entsteht. Damit dieser Hohlraum zwischen Außen- und Innenschale ausgeschäumt werden kann, müssen alle Verbindungen so gestaltet sein, dass der expandierende Isolierschaum weder in den Innenraum eindringen, noch aus der Außenschale herausgedrückt werden kann.Refrigerators are usually made of an outer shell and an inner shell surrounding an interior. The outer shell has a bottom, a lid, two side parts and a rear wall. The inner housing is usually made of a thermoplastic material and deep drawn. The outer dimensions of the inner shell are smaller than the inner dimensions of the outer shell. The two shells are dimensioned so that a cavity is created between the shells during assembly. For this cavity between the outer and inner shell can be filled with foam, all compounds must be designed so that the expanding insulating foam can neither penetrate into the interior, nor can be pushed out of the outer shell.
Kabel, die in dem oder durch den Hohlraum verlaufen, werden vor dem Einbringen des Isolierschaums eingezogen. Da zumindest ein Teil der Kabel in der Nähe des Maschinenraums durch die Rückwand der Außenschale geführt werden muss, müssen diese Kabeldurchführungen abgedichtet werden, damit kein Isolierschaum austritt. Hierzu ist als Kabeldurchführung ein Rohrstutzen vorgesehen. Der Rohrstutzen ist fest mit dem Außengehäuse verbunden. Durch diesen Rohrstutzen wird das Kabel gefädelt. Anschließend wird die verbleibende Rohröffnung mit einem Schaumstoffteil verschlossen, das um das Kabel montiert ist und das Kabel an der richtigen Position fixiert. Der Rohrstutzen ist nach der Montage des Kabels folglich gegen ein Austreten des Isolierschaums gesichert. Es hat sich jedoch gezeigt, dass das Durchfädeln der Kabel durch die Rohrstutzen zeitaufwändig ist. Die Rohrstutzen besitzen an der Innenseite einen Kragen, der als Anschlag für das Schaumstoffteil dient. An diesem Kragen bleiben beim Durchfädeln die mit Kontakten versehenen Adern der Kabel oft hängen. Nach dem zeitaufwändigen Durchfädeln muss dann - in einem zusätzlichen Arbeitsschritt - noch das Schaumstoffteil zur Abdichtung des Rohrstutzens montiert werden.Cables running in or through the cavity are retracted prior to introduction of the insulating foam. Since at least some of the cables near the engine room must be routed through the rear wall of the outer shell, these cable glands must be sealed so that no insulating foam escapes. For this purpose, a pipe socket is provided as a cable bushing. The pipe socket is firmly connected to the outer housing. Through this pipe socket, the cable is threaded. Subsequently, the remaining tube opening is closed with a foam part which is mounted around the cable and fixes the cable in the correct position. The pipe socket is thus secured after the installation of the cable against leakage of Isolierschaums. However, it has been shown that the threading through the cable through the pipe socket is time consuming. The pipe sockets have on the inside a collar which serves as a stop for the foam part. At this collar, the wires of the cables, which are provided with contacts, often remain hanging during threading. After the time-consuming threading - then in an additional step - the foam part must be mounted to seal the pipe socket.
Der Erfindung liegt die Aufgabe zugrunde, ein Kältegerät so zu gestalten, dass durch die Innen- oder Außenschale zu führende Kabel schneller montiert werden können. Ebenso soll auf die zusätzliche Montage einer Dichtung verzichtet werden. Zudem soll die Lösung kostengünstig realisierbar sein.The invention has for its object to make a refrigeration device so that through the inner or outer shell to lead cable can be mounted faster. Likewise, should be dispensed with the additional installation of a seal. In addition, the solution should be inexpensive to implement.
Gelöst wird die Aufgabe gemäß der Erfindung durch ein Kältegerät mit den Merkmalen von Anspruch 1. Erfindungsgemäß ist die Kabelführung als offene Halbschale ausgebildet, die in ihrem Inneren eine Dichtung und Mittel zum Fixieren eines Kabels aufweist, zwischen die das Kabel eindrückbar ist. Zudem ist die Kabelführung so montiert, dass die offene Seite der Halbschale durch einen Teil der Innen- oder Außenschale verschließbar ist. Mit dieser erfindungsgemäßen Ausformung der Kabelführung ist es nun möglich, das Kabel in die Dichtung, die Bestandteil der offenen Halbschale ist, einzudrücken. Um das Eindrücken des Kabels durchzuführen, ist die Halbschale während der Montage von ihrer offenen Seite her zugänglich. Nach der Montage wird die offene Seite dagegen verschlossen, damit kein Isolierschaum durch die Kabelführung nach Außen dringen kann.The object is achieved according to the invention by a refrigerator with the features of claim 1. According to the cable guide is formed as an open half-shell, which has in its interior a seal and means for fixing a cable, between which the cable is pressed. In addition, the cable guide is mounted so that the open side of the half-shell can be closed by a part of the inner or outer shell. With this inventive design of the cable guide, it is now possible to press the cable into the seal, which is part of the open half-shell. To carry out the insertion of the cable, the half-shell is accessible from its open side during assembly. After installation, however, the open side is closed, so that no insulating foam can penetrate through the cable guide to the outside.
Damit das Kabel nach dem Eindrücken in die Kabelführung in axialer Richtung nicht bewegt werden kann, wird es mit Mitteln fixiert, die sich erfindungsgemäß im Inneren der offenen Halbschale befinden. Eine axiale Bewegung der Kabel ist unerwünscht, da die Kabel ansonsten einen Zug auf die elektrischen oder elektronischen Komponenten ausüben könnten, an denen sie montiert sind. Werden die Kabel in dieser belasteten Stellung durch den ausgehärteten Isolierschaum fixiert, kann dieser Zug in Verbindung mit den im Betrieb durch den Kältemittelverdichter erzeugten Vibrationen zu einem Ausfall der elektrischen oder elektronischen Komponenten führen.So that the cable can not be moved in the axial direction after being pressed into the cable guide, it is fixed by means which, according to the invention, are located inside the open half-shell. An axial movement of the cables is undesirable because otherwise the cables could exert a pull on the electrical or electronic components to which they are mounted. If the cables are fixed in this loaded position by the hardened insulating foam, this train can be used in conjunction with cause the vibrations generated during operation by the refrigerant compressor to failure of the electrical or electronic components.
Zur Fixierung des Kabels sind verschiedene Methoden bekannt geworden. So könnte das Kabel beispielsweise in der Kabelführung mäanderförmig geführt werden. Dies ließe die Kabelführung aber relativ breit bauen. Auch könnte das Kabel durch das Aufstecken eines Clips, der mit der Kabelführung verrastet, fixiert werden. In besonders vorteilhafter Weise sind die Mittel zum Fixieren des Kabels hier deshalb als Rippen ausgeformt. Jede dieser Rippen ist fest mit der Halbschale verbunden und weist an der Stelle, an der nach der Montage das Kabel verläuft, eine U-förmige Aussparung auf. Der Abstand der beiden Schenkel ist geringer als der Kabeldurchmesser. Somit kommt es beim Eindrücken des Kabels zwischen die Rippen zu einer radialen Quetschung des Kabels. Dies führt zu der gewünschten axialen Fixierung, ohne dass zusätzliche Komponenten benötigt werden oder die Kabelführung unverhältnismäßig groß baut.For fixing the cable, various methods have become known. For example, the cable could be meandered in the cable guide. This would make the cable management but relatively wide. Also, the cable could be fixed by attaching a clip that locks with the cable guide. In a particularly advantageous manner, the means for fixing the cable are therefore formed here as ribs. Each of these ribs is fixedly connected to the half shell and has a U-shaped recess at the point where the cable runs after installation. The distance between the two legs is less than the cable diameter. Thus, when the cable is forced in between the ribs, there is a radial crushing of the cable. This leads to the desired axial fixation without the need for additional components or disproportionate cable routing.
In besonders vorteilhafter Weise ist die Dichtung als eine Membran an dem in denIn a particularly advantageous manner, the seal is used as a membrane on the in the
Hohlraum ragenden Ende der Kabelführung ausgeführt. Damit kann das der Membran gegenüberliegende Ende, entsprechend den Erfordernissen an die Befestigung, frei gestaltet werden, ohne dass damit die Dichtfunktion der Membran durch die Befestigungsart beeinträchtigt wird. Befestigungsmöglichkeiten sind z. B. Verrasten, Schrauben oder Stecken. Andererseits wird durch die erfindungsgemäße Lage derCavity projecting end of the cable guide executed. Thus, the membrane opposite end, according to the requirements of the attachment, be designed freely, without affecting the sealing function of the membrane is affected by the fastening. Mounting options are z. B. latching, screwing or plugging. On the other hand, by the inventive situation of
Membran sichergestellt, dass evtl. durch die Membran hindurchtretende kleinere Mengen an Isolierschaum in der Kabelführung gefangen und nicht nach Außen herausgedrückt werden.Membrane ensures that any smaller amounts of insulating foam passing through the membrane are trapped in the cable guide and not pushed outwards.
Damit das Kabel in die Kabelführung eindrückbar ist, ist die Membran vorteilhafterweise mit einem Schlitz versehen. Hierdurch kann nun das Kabel im gleichen Arbeitsgang, in dem das Kabel zwischen die Rippen gedrückt wird, auch in die Dichtung eingedrückt werden. Auch hier zeigt sich, wie vorteilhaft die Verwendung einer Membran als Dichtung ist, da diese während des Eindrückens nachgibt und damit keinen erhöhten Kraftaufwand erfordert.Thus, the cable is pressed into the cable guide, the membrane is advantageously provided with a slot. In this way, the cable can now be pressed into the seal in the same operation in which the cable is pressed between the ribs. Again, it shows how advantageous the use of a membrane as a seal, as this yields during the depression and thus no increased effort requires.
In vorteilhafter Weise weist die Membran in ihrer Mitte eine Öffnung auf, die so dimensioniert ist, dass die Membran das Kabel spaltfrei umschließt. Dadurch wird das Eindringen von Schaum in die Kabelführung größtenteils verhindert. Durch ihre Elastizität kann sich die Membran in radialer Richtung an die Form des Kabels hervorragend anpassen.Advantageously, the membrane has in its center an opening which is dimensioned so that the membrane surrounds the cable gap-free. This largely prevents the ingress of foam into the cable duct. Due to their elasticity, the membrane can adapt itself in the radial direction to the shape of the cable outstanding.
Wenn nun mehrere Kabel durch die Innen- oder Außenschale geführt werden müssen, ist es möglich, für jedes Kabel eine eigene Kabelführung in Form einer Halbschale zu montieren. Dies bedeutet einen nicht unerheblichen Arbeitsaufwand bei der Montage. Wenn nun auch noch mehrere Kabeldurchmesser und damit unterschiedliche Kabelführungen verwendet werden, besteht Verwechslungsgefahr. Ein zu dickes Kabel lässt sich dann in die Kabelführung nicht eindrücken und die Kabelführung muss getauscht werden. Nachteiliger ist es jedoch, wenn sich ein zu dünnes Kabel in die nicht passende Kabelführung eindrücken lässt, sich aber die Membran nicht spaltfrei um das Kabel legt, so dass es beim darauf folgenden Schäumprozess zu einem Schaumdurchtritt kommt.If several cables have to be routed through the inner or outer shell, it is possible to mount a separate cable guide in the form of a half shell for each cable. This means a considerable amount of work during installation. If now even more cable diameters and thus different cable guides are used, there is a risk of confusion. An excessively thick cable can then not be pressed into the cable guide and the cable guide must be replaced. However, it is more disadvantageous if a cable which is too thin can be pressed into the cable guide which is not suitable, but the membrane does not wrap around the cable without a gap, so that foaming occurs during the subsequent foaming process.
In vorteilhafter weise werden deshalb mehrere Halbschalen nebeneinander zu einer Kabelführung angeordnet. Besonders vorteilhaft ist es zudem, dass die nebeneinander liegenden Halbschalen für unterschiedliche Kabeldurchmesser ausgelegt sind. Somit kann jede Halbschale auf das Kabel, das sie später aufnehmen soll, optimiert werden. Da alle vorhandenen Kabel in diesen miteinander verbundenen Halbschalen untergebracht werden müssen, wird die Verwechslungsgefahr enorm reduziert. Auch lässt sich so Materialverschwendung vermeiden und die Kabelführung erfährt eine sehr kompakte Ausführung.Advantageously, therefore, several half shells are arranged side by side to a cable guide. It is also particularly advantageous that the adjacent half-shells are designed for different cable diameters. Thus, each half-shell can be optimized for the cable which it is to receive later. Since all existing cables must be accommodated in these interconnected half-shells, the likelihood of confusion is enormously reduced. This also avoids wasting of material and the cable routing is very compact.
In vorteilhafter Weise sind zwei Halbschalen für die Aufnahme von Kabeln über einen Steg miteinander verbunden. Auf diesem Steg kann ein Kabel mit kleinem Durchmesser befestigt werden. Auf diese Weise erhöht sich der Materialaufwand für eine Kabelführung zur Aufnahme von drei Kabeln nur unmerklich gegenüber einer Kabelführung zur Aufnahme von zwei Kabeln.Advantageously, two half shells for receiving cables over a Footbridge interconnected. A small diameter cable can be attached to this bridge. In this way, the cost of materials for a cable guide for receiving three cables increases only imperceptibly compared to a cable guide for receiving two cables.
Die Kabelführung mit der Dichtung und den Rippen wird vorteilhaft aus dem selbenThe cable guide with the seal and the ribs is advantageously made of the same
Material hergestellt. Hierdurch ist es möglich, die Kabelführung einstückig auszubilden. Ein weiterer Fertigungsschritt, um die Funktionstüchtigkeit der Kabelführung herzustellen, wie z. B. das Einkleben der Dichtung entfällt dadurch. Besonders vorteilhaft ist es, die Kabelführung als Kunststoffspritzteil auszubilden, da sich Kunststoffspritzteile in großer Menge sehr preiswert fertigen lassen.Material produced. This makes it possible to form the cable guide in one piece. Another manufacturing step to make the functionality of the cable guide, such. B. the gluing of the seal is eliminated. It is particularly advantageous to design the cable guide as a plastic injection-molded part, since plastic injection-molded parts can be produced very inexpensively in large quantities.
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.

Von diesem Maschinenraum 1 werden Kabel 2 und 3 durch Eintrittslöcher 4 geführt, die sich in einem Teil der Außenschale 5 befinden und zum Rand 6 hin offen sind. Der nach der Montage des Kältegeräts abgeschlossene Hohlraum 7 ist im fertigen Produkt mit Isolierschaum gefüllt.Figure 1 shows a section of a refrigerator in the vicinity of the engine room 1, which accommodates, inter alia, the refrigerant compressor, not shown here. From this machine room 1 cables 2 and 3 are guided through inlet holes 4, which are located in a part of the outer shell 5 and the edge 6 are open. The after assembly the refrigerator finished cavity 7 is filled in the finished product with insulating foam.
Die Kabel 2 und 3 sind in eine Kabelführung 8 eingedrückt. Diese Kabelführung 8 ist an einer ihrer Stirnseiten mit der Außenschale 5 verbunden. Ihre offene Seite schließt mit dem Rand 6 bündig ab, so dass durch das Aufsetzen einer zu der Außenschale 5 gehörenden Seitenwand die offene Seite der Kabelführung 8 dicht verschlossen werden kann. Die Kabelführung 8 weist die Form von zwei offenen Halbzylindern 9 auf, die durch einen Steg 10 fest miteinander verbunden sind. Dieser Steg 10 weist eine ebenfalls offene Rinne 14 zur Aufnahme des dünnen Kabels 3 auf. Um die offene Seite der Kabelführung 8 verläuft der Dichtrand 12. Wenn die Seitenwand montiert wird, liegt sie auf dem Dichtrand 12 auf und verschließt so die offene Seite der Kabelführung 8.The cables 2 and 3 are pressed into a cable guide 8. This cable guide 8 is connected at one of its end faces with the outer shell 5. Their open side is flush with the edge 6, so that the open side of the cable guide 8 can be tightly closed by placing a side wall belonging to the outer shell 5. The cable guide 8 has the shape of two open half-cylinders 9, which are connected by a web 10 firmly together. This web 10 has an also open channel 14 for receiving the thin cable 3. When the side wall is mounted, it rests on the sealing edge 12 and thus closes the open side of the cable guide eighth
Innerhalb eines jeden Halbzylinders 9 befinden sich drei Rippen 13, die senkrecht zur Innenwandung des Halbzylinders 9 stehen. Jede in den Zylinderhälften verlaufende Rippe 13 ist mittig U-förmig ausgespart. Der Abstand der U-Schenkel zueinander ist so dimensioniert, dass das Kabel 2 zuverlässig fixiert wird. Die Rippen 13 sind bis in den Bereich des Stegs 10 verlängert. Die Verlängerungen 1 1 verlaufen schräg in die vom Rand 6 weg weisende Richtung. Somit bildet jeweils ein Paar der Verlängerungen 1 1 eine trichterförmige Führung. In der Mitte des Stegs 10 verläuft die Rinne 14. Die Rinne 14 ist so geformt, dass sie den unteren Teil des dünnen Kabels 3 aufnimmt. Der obere Teil des Kabels 3 wird durch die Verlängerungen 1 1 zuverlässig fixiert. Die Rippen 13 und die Verlängerungen 1 1 sind so hoch gezogen, dass sie bündig mit der durch die Oberkante des Dichtrandes 12 aufgespannten Ebene abschließen.Within each half-cylinder 9 are three ribs 13 which are perpendicular to the inner wall of the half-cylinder 9. Each extending in the cylinder halves rib 13 is recessed centrally U-shaped. The distance between the U-legs to each other is dimensioned so that the cable 2 is reliably fixed. The ribs 13 are extended into the region of the web 10. The extensions 1 1 extend obliquely in the direction away from the edge 6 direction. Thus, each pair of extensions 11 forms a funnel-shaped guide. In the middle of the web 10, the groove 14 extends. The groove 14 is shaped so that it receives the lower part of the thin cable 3. The upper part of the cable 3 is reliably fixed by the extensions 1 1. The ribs 13 and the extensions 1 1 are pulled so high that they are flush with the plane defined by the upper edge of the sealing edge 12 plane.

Um das Kabel 2 in die Öffnung 16 der Membran 15 eindrücken zu können, weist die Membran 15 einen Schlitz 17 auf, der sich von der Öffnung 16 bis zu dem Dichtrand 12 erstreckt. Eine solche Membran ist auch auf dem Steg 10 zur Abdichtung des Kabels 3 vorhanden.Membrane 15 closed, which has a circular opening 16 in its center. The diameter of the opening 16 is dimensioned such that the membrane 15 encloses the pressed-cable 2 gap-free. In order to push the cable 2 into the opening 16 of the membrane 15, the membrane 15 has a slot 17 extending from the Opening 16 extends to the sealing edge 12. Such a membrane is also present on the web 10 for sealing the cable 3.
Natürlich ist es auch möglich, die Kabelführung 8 unter Berücksichtigung der oben beschrieben Merkmale so zu gestalten, dass mehr oder weniger Kabel als hier gezeigt nebeneinander Platz finden. Auch können die Durchmesser der Kabel 2 untereinander variieren.Of course, it is also possible to make the cable guide 8 taking into account the features described above so that more or less cable as shown here side by side place. Also, the diameter of the cable 2 can vary with each other.
Zur Montage wird das Kabel 2 bzw. 3 von dem Eintrittsloch 4 im Rand 6 der Außenschale 5 bis zu der Membran 15 über die Kabelführung 8 gelegt und eingedrückt. Da es sich bei dem zum Rand 6 offenen Eintrittsloch 4 nicht um eine geschlossene Durchführung durch die Außenschale handelt, müssen die Kabel nicht mühsam eingefädelt werden. Durch die Rippen 13 bzw. die Verlängerungen 1 1 wird das Kabel 2 bzw. 3 radial etwas eingeschnürt, so dass es in axialer Richtung zuverlässig fixiert ist.For installation, the cable 2 and 3 is placed and pressed from the inlet hole 4 in the edge 6 of the outer shell 5 to the membrane 15 via the cable guide 8. Since it is not a closed passage through the outer shell at the edge 6 open to the entrance hole 4, the cables do not have to be laboriously threaded. Through the ribs 13 and the extensions 1 1, the cable 2 or 3 is radially constricted something, so that it is reliably fixed in the axial direction.
Nach der Montage der Kabel wird die Seitenwand montiert. Dadurch werden die Kabel 2, 3 auch in radialer Richtung fixiert und können aus der nun allseitig geschlossenen Kabelführung nicht mehr heraus rutschen.After mounting the cables, the sidewall is mounted. As a result, the cables 2, 3 are fixed in the radial direction and can no longer slip out of the now closed on all sides cable guide.
In einem späteren Arbeitsschritt wird der Isolierschaum in den Hohlraum 7 eingespritzt. Da die Kabelführung 8 nun allseitig geschlossen ist, kann praktisch kein Isolierschaum eindringen. Sollte trotzdem eine kleinere Menge Isolierschaum durch die Membran 15 hindurchgedrückt werden, verfängt sich der Schaum an den Rippen 13 und gelangt so nicht bis zum Eintrittsloch 4. Ein Austritt von Isolierschaum in den Maschinenraum 1 ist damit ausgeschlossen. Die Kabelführung 8 ist als ein einstückiges Kunststoffspritzteil ausgebildet und damit kostengünstig herstellbar. In a later step, the insulating foam is injected into the cavity 7. Since the cable guide 8 is now closed on all sides, virtually no insulating foam can penetrate. Should nevertheless a smaller amount of insulating foam be forced through the membrane 15, the foam gets caught on the ribs 13 and thus does not reach the inlet hole 4. An outlet of insulating foam in the engine room 1 is thus excluded. The cable guide 8 is formed as a one-piece plastic injection molded part and thus inexpensive to produce.
