Abstract

A refrigeration device includes a frame and a door that surround a cooling chamber as well as a water pipe that extends inside the frame and the door. A coupling that is separated when the door is open while being connected when the door is closed is disposed between a section of the water pipe extending in the frame and a section of the water pipe extending in the door.

Description

Die vorliegende Erfindung betrifft ein Kältegerät mit einer sich zwischen Korpus und Tür des Kältegeräts erstreckenden Wasserleitung, insbesondere ein Kältegerät, bei dem eine solche Wasserleitung eine an der Tür gebildete Zapfstelle zum Abzapfen von gekühltem Trinkwasser speist.The present invention relates to a refrigeration device with a water pipe extending between the body and the door of the refrigerator, in particular a refrigerator, in which such a water pipe feeds a tapping point formed at the door for tapping cooled drinking water.

Es ist bekannt, bei Kältegeräten dieses Typs die Wasserleitung vom Korpus in die Tür mit Hilfe eines flexiblen Schlauches zu führen, der sich durch ein Schutzrohr eines die Tür mit dem Korpus verbindenden Scharniers entlang der Schwenkachse des Scharniers erstreckt. Ein Kättegerät gemäß dem Oberbegriff vom Anspruch 1 ist bekannt aus US 2004/206106 .It is known, in refrigerators of this type, to guide the water conduit from the body into the door by means of a flexible hose which extends along the pivot axis of the hinge through a protective tube of a hinge connecting the door to the body. A Kättegerät according to the preamble of claim 1 is known from US 2004/206106 ,

Diese Technik ist nur geeignet für Kältegeräte, bei denen Korpus und Tür durch ein einachsiges Scharnier verbunden sind. Bei Mehrgelenkscharnieren, wie sie insbesondere bei Einbaukältegeräten verwendet werden, um eine Tür mit fest aufmontierter Möbelplatte zu führen, ist diese Lösung nicht anwendbar, weil im allgemeinen keine stationäre körperliche Achse der Schwenkbewegung der Tür existiert, entlang derer der Schlauch geführt werden könnte. Es wäre zwar grundsätzlich denkbar, einen Schlauch in der Umgebung eines Mehrgelenkscharniers frei vom Korpus zur Tür zu führen, doch benötigt ein solcher Schlauch viel Platz, und die Gefahr, dass der Schlauch beim Öffnen und Schließen der Tür eingeklemmt und verletzt wird, ist hoch.This technique is only suitable for refrigerators where the body and door are connected by a single-axis hinge. In multi-joint hinges, such as those used in built-in refrigerators to guide a door with permanently mounted furniture panel, this solution is not applicable, because in general there is no stationary physical axis of the pivotal movement of the door, along which the hose could be performed. Although it would be conceivable in principle to guide a hose in the vicinity of a multi-joint hinge freely from the body to the door, but such a hose requires a lot of space, and the risk that the hose is pinched and injured when opening and closing the door, is high.

Ein genereller Nachteil des Führens eines Schlauchs über das Gelenk zwischen Korpus und Tür ist ferner, dass ein Anschlagwechsel der Tür nur möglich ist, wenn die Möglichkeit besteht, den Verlauf der Wasserleitung im Korpus nachträglich zu verändern, so dass der Austritt der Wasserleitung aus dem Korpus bei einer Verlegung des Türscharniers nachgeführt werden kann.A general disadvantage of passing a hose over the joint between the body and door is further that an attack change of the door is only possible if there is a possibility to subsequently change the course of the water pipe in the body, so that the outlet of the water pipe from the body can be tracked at a laying of the door hinge.

Aufgabe der vorliegenden Erfindung ist daher, eine andere Lösung zum Führen einer Wasserleitung zwischen Korpus und Tür eines Kältegerätes zu finden, die keinen Einschränkungen hinsichtlich des Typs des zwischen Korpus und Tür verwendeten Scharniers unterliegt und eine kompakte Bauform des Geräts ermöglicht.Object of the present invention is therefore to find another solution for guiding a water pipe between the body and door of a refrigerator, which is not subject to restrictions on the type of hinge used between the carcass and door and allows a compact design of the device.

Die Aufgabe wird dadurch gelöst, dass bei einem Kältegerät mit einem Korpus und einer Tür, die einen Kühlraum umschließen, und mit einer sich in dem Korpus und der Tür erstreckenden Wasserleitung zwischen einem im Korpus verlaufenden Stück der Wasserleitung und einem in der Tür verlaufenden Stück derselben eine bei offener Tür getrennte und bei geschlossener Tür verbundene Kupplung angeordnet ist.The object is achieved in that in a refrigerator with a body and a door which enclose a refrigerator, and with a extending in the body and the door water pipe between a running in the body piece of the water pipe and a running in the door piece of the same a separate door open and connected with the door closed coupling is arranged.

Um im getrennten Zustand der Kupplung den Austritt von Wasser zu vermeiden, weist die Kupplung vorzugsweise an einer stromaufwärtigen Seite ein selbstschließendes Ventil auf.In order to avoid the escape of water in the disconnected state of the coupling, the coupling preferably has a self-closing valve on an upstream side.

Dieses Ventil kann zweckmäßigerweise einen gegen einen Sitz beaufschlagten Dichtkörper aufweisen, der bei geschlossener Tür durch einen an die stromabwärtige Seite der Kupplung gekoppelten Vorsprung von dem Sitz ferngehalten ist, um so das Ventil offen zu halten und das Fließen von Wasser zu ermöglichen.This valve may conveniently comprise a seated sealing member which, with the door closed, is kept away from the seat by a projection coupled to the downstream side of the coupling so as to keep the valve open and allow water to flow.

An der stromabwärtigen Seite der Kupplung ist vorzugsweise ein Rückschlagventil vorgesehen, um auch dort einen Austritt von Wasser beim Trennen der Kupplung zu vermeiden.On the downstream side of the clutch, a check valve is preferably provided in order to avoid leakage of water when disconnecting the clutch there.

Einer zweckmäßigen Weiterbildung zufolge umfasst die Kupplung ein Stiftteil und ein Buchsenteil, die bei geschlossener Tür steckverbunden sind und von denen wenigstens eines quer zur Steckrichtung verschieblich ist. Die Verschieblichkeit erhöht zum einen die Toleranzen bei der Montage von Korpus und Tür aneinander, zum anderen ermöglicht sie eine selbsttätige Anpassung der Positionen der Kupplungsteile in Bezug aufeinander, wenn sich, sei es durch mechanische Belastung, Alterung oder andere Ursachen, die Tür in Bezug auf den Korpus quer zur Richtung ihrer Öffnungs- und Schließbewegung verlagert.According to an expedient development, the coupling comprises a pin part and a socket part which are plug-connected with the door closed and of which at least one is displaceable transversely to the plug-in direction. The mobility increases on the one hand, the tolerances in the assembly of the body and door together, on the other hand, it allows an automatic adjustment of the positions of the coupling parts with respect to each other, if, due to mechanical stress, aging or other causes, the door in relation to displaced the body transversely to the direction of its opening and closing movement.

Eine zur Eingangsseite hin aufgeweitete Aufnahmebohrung für das Stiftteil in dem Buchsenteil erleichtert ein selbsttätiges Ausrichten der Kupplungsteile in Bezug aufeinander beim Schließen der Tür, wenn eine Verlagerung der Tür in Bezug auf den Korpus aufgetreten ist.A receiving bore for the pin part in the socket part widened toward the input side facilitates automatic alignment of the coupling parts with respect to one another when closing the door when a displacement of the door with respect to the body has occurred.

Wenn die Wasserleitung genutzt ist, um damit eine Zapfstelle an der Tür zu speisen, so ist zweckmäßigerweise ein Auslassventil der Wasserleitung an der Zapfstelle eingerichtet, um nur bei geschlossener Tür zu öffnen. Auf diese Weise wird vermieden, dass bei geöffneter Tür aus dem in dieser verlaufenden Stück der Wasserleitung das Wasser abgelassen wird, was bei einem späteren Schließen der Tür dazu führen würde, dass in der Leitung befindliche Luft durch den Druck des Wassers komprimiert wird und bei einem späteren Zapfvorgang unter Spritzen und Geräuschentwicklung austritt.If the water pipe is used to feed a tapping point on the door, it is expediently an outlet valve of the water pipe at the tap set up to open only when the door is closed. In this way it is avoided that when the door is open from the running in this piece of water pipe, the water is drained, which would lead to a subsequent closing of the door to air in the line is compressed by the pressure of the water and at a later tapping under spraying and noise escapes.

Um eine solche Kopplung der Ventilfunktion an die Stellung der Tür zu erzielen, ist vorzugsweise zwischen Korpus und Tür ein elektrischer Schalter angeordnet, der bei geöffneter Tür offen und bei geschlossener Tür geschlossen ist, und das Auslassventil ist ein elektrisch geschaltetes Ventil, das über den Schalter mit Betriebsenergie versorgt wird.In order to achieve such a coupling of the valve function to the position of the door, an electrical switch is preferably arranged between the body and door, which is open with the door open and closed with the door closed, and the outlet valve is an electrically switched valve, which via the switch is supplied with operating energy.

Eine mittige Anordnung der Kupplung zwischen zwei Seitenwänden des Korpus erleichtert einen Anschlagwechsel der Tür, da es nicht erforderlich ist, den Verlauf der Wasserleitung bei einem Anschlagwechsel anzupassen.A central arrangement of the coupling between two side walls of the body facilitates an attack change of the door, since it is not necessary to adjust the course of the water pipe in a stop change.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Es zeigen:Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Fig. 5 einen Schnitt durch die Kupplung bei geschlossener Tür. Fig. 5 a section through the clutch with the door closed.

Das in Fig. 1 gezeigte Kältegerät hat einen Korpus 1 und eine Tür 2, die gemeinsam einen Kühlraum 3 begrenzen und miteinander durch schematisch dargestellte Mehrgelenkscharniere 4 verbunden sind.This in Fig. 1 shown refrigeration device has a body 1 and a door 2, which together define a cooling space 3 and are connected to each other by schematically illustrated multi-joint hinges 4.

Am Oberteil des der Tür zugewandten Rahmens 5 des Korpus 1 ist ein elektrischer Schalter 6 angeordnet, von dem ein über die Vorderseite des Rahmens 5 überstehender, durch die Tür 2 betätigbarer Stift in der Fig. zu sehen ist. Der Schalter 6 schaltet zwei Kontakte, und zwar einen für die Innenraumbeleuchtung des Kühlraums 3, der in bekannter Weise bei offener Tür 2 geschlossen und bei geschlossener Tür offen ist, und einen zweiten Kontakt, der bei offener Tür offen und bei geschlossener Tür geschlossen ist.On the upper part of the door-facing frame 5 of the body 1, an electrical switch 6 is arranged, from which an over the front of the frame 5 projecting, actuated by the door 2 pin in the Fig. Can be seen. The switch 6 switches two contacts, one for the interior lighting of the refrigerator compartment 3, which is closed in a known manner with the door open 2 and open with the door closed, and a second contact which is open with the door open and closed when the door is closed.

In einer Aussparung 7, die wie der Schalter 6 in etwa mittig an dem Oberteil des Rahmens 5 angeordnet ist, ist ein Buchsenteil 8 angeordnet, welches das stromabwärtige Ende eines durch die Wand des Korpus 1 verlaufenden Stücks einer Wasserleitung bildet. Das Buchsenteil 8 ist vorgesehen, um bei geschlossener Tür 2 ein an der Tür 2 vorspringendes Stiftteil 9 aufzunehmen, welches das stromaufwärtige Ende eines in der Tür 2 verlaufenden Teils der Wasserleitung bildet. Die Wasserleitung erstreckt sich - in der Figur nicht sichtbar - in der Tür 2 bis zu einer an deren Vorderseite gebildeten Nische 10 (siehe Fig. 2). In der Nische 10 befindet sich ein in der Perspektive der Fig. 2 verdecktes Auslassventil und ein Taster 11, der, z.B. mit einem unter das Auslassventil gehaltenen Becher, gedrückt werden kann, um das Auslassventil aufzuschalten und Wasser zu zapfen. Das Auslassventil ist ein elektrisch betätigtes Ventil, z. B. ein Magnetventil, das im stromlosen Zustand geschlossen ist. Es ist über den zweiten Kontakt des Schalters 6 mit Betriebsspannung versorgt, so dass es bei offener Tür 2 unabhängig von einer Betätigung oder Nichtbetätigung des Tasters 11 stets sperrt und nur bei geschlossener Tür 2 geöffnet werden kann.In a recess 7, which is like the switch 6 is arranged approximately centrally on the upper part of the frame 5, a socket part 8 is arranged, which forms the downstream end of a running through the wall of the body 1 piece of a water pipe. The female part 8 is provided to receive a door part 2 projecting pin part 9 with the door closed 2, which forms the upstream end of a running in the door 2 part of the water pipe. The water pipe extends - not visible in the figure - in the door 2 to a niche 10 formed at the front (see Fig. 2 ). In the niche 10 is a in the perspective of Fig. 2 concealed exhaust valve and a button 11, which can be pressed, for example with a held under the exhaust valve cup, to turn on the exhaust valve and tap water. The exhaust valve is an electrically operated valve, e.g. B. a solenoid valve which is closed in the de-energized state. It is supplied via the second contact of the switch 6 with operating voltage, so that it always locks with an open door 2 regardless of an operation or non-actuation of the button 11 and can be opened only when the door 2 is closed.

Fig. 3 zeigt einen axialen Schnitt durch das Buchsenteil 8 und das Stiftteil 9 bei geöffneter Tür 2. Das Stiftteil 9 umfasst ein Rohrstück 12, das an seinem Einlassende verengt ist, um einen Ventilsitz 13 für einen Ventilkörper 14 zu bilden, der auf einem Stab 15 verschiebbar geführt ist. Ein erstes Ende des Stabs 15 ist im Innern des Rohrstücks 12 verankert; das andere steht über das Ende des Rohrstücks 12 hinaus vor. Eine auf den Stab 15 aufgesteckte Schraubenfeder 16 hält den Ventilkörper 14 gegen den Ventilsitz 13 gedrückt, so dass kein Wasser aus dem Rohrstück 12 austreten kann. Fig. 3 shows an axial section through the socket part 8 and the pin part 9 with the door 2 open. The pin part 9 comprises a tube piece 12 which is narrowed at its inlet end to form a valve seat 13 for a valve body 14, which guided on a rod 15 slidably is. A first end of the rod 15 is anchored in the interior of the pipe section 12; the other protrudes beyond the end of the pipe section 12. A plugged onto the rod 15 coil spring 16 holds the valve body 14 pressed against the valve seat 13, so that no water can escape from the pipe section 12.

Dem Rohrstück 8 liegt nicht exakt fluchtend das Buchsenteil 8 gegenüber. Das Buchsenteil hat einen im wesentlichen zylindrischen Körper 17, in dem eine zu ihrer Eingangsseite hin kegelförmig aufgeweitete Aufnahmebohrung 18 für das Stiftteil 9 gebildet ist. In die Wand der Aufnahmebohrung 18 sind Dichtringe 19 eingelassen.The pipe section 8 is not exactly aligned with the female part 8. The female part has a substantially cylindrical body 17, in which a receiving bore 18 which is widened conically towards its input side is formed for the pin part 9. In the wall of the receiving bore 18 sealing rings 19 are inserted.

Ein von dem zylindrischen Körper 17 ringförmig abstehender Flansch 20 greift zwischen zwei parallele Wände 21 des Rahmens 5 ein und ist zwischen diesen reibschlüssig aber verschieblich gehalten.One of the cylindrical body 17 annularly projecting flange 20 engages between two parallel walls 21 of the frame 5 and is frictionally but slidably held between them.

Am Boden der Aufnahmebohrung 18 ist ein selbstschließendes Ventil 22 angeordnet. Es umfasst einen Ventilkörper 23, der durch eine Schraubenfeder 24 gegen einen Ventilsitz 25 gedrückt gehalten ist. Stromaufwärts von dem Ventil 22 ist ein flexibler Schlauch 26 an dem Körper 17 befestigt. Körper 17 und Schlauch 26 sind in einem Hohlraum 27 aufgenommen, der aus einer ansonsten die Wände des Korpus 1 ausfüllenden Isoliermaterialschicht 28 ausgespart ist. Der Schlauch 26 bildet einen beweglichen Übergang zu einem nicht dargestellten, starren Rohrstück, das in die Isoliermaterialschicht 28 eingebettet ist. Wenn dieses Rohrstück an eine externe Frischwasserleitung angeschlossen ist, wirkt der Druck des Frischwassers unterstützend zur Kraft der Schraubenfeder 24 auf den Ventilkörper 23 und hält diesen dicht gegen den Sitz 25 gepresst.At the bottom of the receiving bore 18, a self-closing valve 22 is arranged. It comprises a valve body 23, which is held pressed by a coil spring 24 against a valve seat 25. Upstream of the valve 22, a flexible hose 26 is attached to the body 17. Body 17 and tube 26 are received in a cavity 27 which is recessed from an otherwise filling the walls of the body 1 insulating material layer 28. The tube 26 forms a movable transition to a non-illustrated, rigid tube piece which is embedded in the insulating material layer 28. If this piece of pipe is connected to an external fresh water line, the pressure of the fresh water acts in support of the force of the coil spring 24 on the valve body 23 and keeps it pressed tightly against the seat 25.

Fig. 4 zeigt einen zweiten Schnitt durch das Buchsenteil 8 und das Stiftteil 9 in einem Stadium, in dem sich diese beim Schließen der Tür 2 erstmalig berühren. Das Stiftteil 9 stößt an den kegelartig aufgeweiteten Einlassbereich der Aufnahmebohrung 18 des Buchsenteils 8 und schiebt dieses, während es vordringt, beiseite, so dass es schließlich exakt zentriert in die Aufnahmebohrung 18 hineingleitet. Fig. 4 shows a second section through the socket part 8 and the pin part 9 in a state in which they touch the first time when closing the door 2. The pin member 9 abuts the conically widened inlet portion of the receiving bore 18 of the female part 8 and pushes this while it penetrates, aside, so that it finally slides exactly centered in the receiving bore 18.

Fig. 5 zeigt das Stiftteil 9 bis zum Anschlag in das Buchsenteil 8 eingerückt, bei geschlossener Tür 2. In dieser Stellung ist der Ventilkörper 23 des Ventils 22 durch die über das Rohrstück 12 vorstehende Spitze des Stabs 15 zurückgedrückt, so dass das Ventil 22 offen ist. Die von dem Rohrstück 12 umgebogenen, einwärts gerichteten Lippen 29 der Dichtringe 19 werden vom Wasserdruck gegen das Rohrstück 12 gedrückt und dichten die Kupplung nach außen ab. Fig. 5 In this position, the valve body 23 of the valve 22 is pushed back by the projecting over the pipe section 12 tip of the rod 15 so that the valve 22 is open. The bent of the pipe section 12, inward directed lips 29 of the sealing rings 19 are pressed by the water pressure against the pipe section 12 and seal the coupling to the outside.

Wenn an der Zapfstelle das Auslassventil geöffnet wird und dadurch der Wasserdruck zwischen dem Auslassventil und dem Stiftteil 9 zusammenbricht, wird der der Ventilkörper 14 vom Ventilsitz 13 zurückgedrängt, und Frischwasser strömt nach. Sobald das Auslassventil geschlossen wird, drückt die Schraubenfeder 16 den Ventilkörper 14 wieder gegen seinen Sitz 13, und das durch die Tür 2 verlaufende Stück der Wasserleitung ist an beiden Enden geschlossen.When the outlet valve is opened at the tapping point and thereby the water pressure between the outlet valve and the pin part 9 collapses, the valve body 14 is pushed back from the valve seat 13, and fresh water flows after. Once the exhaust valve is closed, the coil spring 16 presses the valve body 14 against its seat 13 again, and the piece of water pipe passing through the door 2 is closed at both ends.
