Description

Vorrichtung zur Verbindung einer externen Wasserzuführung mit einer internen Wasserführung einer Waschmaschine Device for connecting an external water supply with an internal water supply of a washing machine
Die Erfindung betrifft eine Vorrichtung zur Verbindung einer externen Wasserzuführung mit einer internen Wasserführung eines Hausgeräts zur Pflege von Wäschestücken, insbesondere einer Waschmaschine oder eines Waschtrockners.The invention relates to a device for connecting an external water supply with an internal water supply of a household appliance for the care of laundry items, in particular a washing machine or a washer dryer.
Bei Waschmaschinen ist es bekannt, dass sie einen externen Zulaufschlauch aufweisen, über den Wasser von einer Hauswasserversorgung zur Waschmaschine geleitet werden kann. Darüber hinaus ist es bekannt, dass derartige Waschmaschinen ein Sicherheitsventil aufweisen, um die Wasserzuführung absperren oder freigeben zu können, und eine Aqua-Stop-Funktionalität aufweisen.In washing machines, it is known that they have an external inlet hose, can be passed through the water from a domestic water supply to the washing machine. In addition, it is known that such washing machines have a safety valve to shut off or release the water supply, and have an aqua-stop functionality.
Bei bekannten Geräten ist die Anbringung bzw. Montage des Sicherheitsventils und des Wasserleitsystems separiert und erfordert daher einen erheblichen Aufwand. Darüber hinaus sind dadurch unterschiedliche Geräteanschlüsse gegeben. Nicht zuletzt wird durch die getrennte Montage des Sicherheitsventils und des Wasserleitsystems ein erheblicher Platzbedarf benötigt.In known devices, the attachment or assembly of the safety valve and the water supply system is separated and therefore requires considerable effort. In addition, this gives different device connections. Last but not least, a considerable amount of space is required due to the separate installation of the safety valve and the water supply system.
Daher ist es Aufgabe der vorliegenden Erfindung, eine Vorrichtung zu schaffen, mit der die Montage von Komponenten eines wasserführenden Zweigs eines Hausgeräts vereinfacht werden kann.It is therefore an object of the present invention to provide a device with which the assembly of components of a water-bearing branch of a domestic appliance can be simplified.
Diese Aufgabe wird durch eine Vorrichtung, welche die Merkmale nach Anspruch 1 auf- weist, gelöst.This object is achieved by a device which has the features according to claim 1.
Eine erfindungsgemäße Vorrichtung zur Verbindung einer externen Wasserzuführung mit einer internen Wasserführung eines Hausgeräts zur Pflege von Wäschestücken, insbesondere einer Waschmaschine oder einem Waschtrockner, umfasst ein Gehäuse, indem ein Ende einer externen Wasserzuführleitung angeordnet ist. Darüber hinaus umfasst die Vorrichtung ein Sicherheitsventil zum Absperren oder Freigeben zumindest einer geräteinternen Wasserführung, welches ebenfalls zumindest bereichsweise in dem Gehäuse angeordnet ist. Die Schnittstelle zwischen der externen Wasserzuführung und der internen Wasserführung des Hausgeräts ist in dem Gehäuse realisiert. Das Gehäuse weist darüber hinaus eine Öffnung zur Abführung von Leckagewasser auf. Durch die erfindungsgemäße Vorrichtung kann eine kompakte und bauraumminimierte Ausgestaltung ermöglicht werden, indem eine gehäuseinterne Positionierung von Komponenten für die externe Wasserzuführung, der internen Wasserführung, dem Sicherheitsventil und einem internen Leckagewasserleitsystem integriert sind. Diese Ausgestaltung gewährleistet neben einer bauraumminimierten Anordnung auch eine Bauteilreduzierung, da die gesamte Vorrichtung als Gesamtes montiert werden kann und nicht mehr das Sicherheitsventil und das Wasserleitsystem getrennt am Gerät montiert werden müssen.A device according to the invention for connecting an external water supply with an internal water supply of a domestic appliance for the care of laundry items, in particular a washing machine or a washer-dryer, comprises a housing in which one end of an external water supply line is arranged. In addition, the device comprises a safety valve for shutting off or releasing at least one device-internal water supply, which also at least partially in the housing is arranged. The interface between the external water supply and the internal water supply of the domestic appliance is realized in the housing. The housing also has an opening for removing leakage water. By the device according to the invention a compact and space-minimized design can be made possible by an in-house positioning of components for the external water supply, the internal water supply, the safety valve and an internal leakage water control system are integrated. This design ensures next to a space-minimized arrangement and a component reduction, since the entire device can be mounted as a whole and no longer the safety valve and the water supply system must be mounted separately on the device.
Vorzugsweise umfasst das Gehäuse eine erste Kammer, in welcher das Ende der externen Wasserzuführleitung angeordnet ist. Des Weiteren umfasst das Gehäuse vorzugsweise eine zweite Kammer, in welcher das Sicherheitsventil zumindest bereichsweise angeordnet ist. Durch ein derartiges Kammersystem im Gehäuse kann auch ein Dichtsys- tem im Hinblick auf Austreten des Leckagewassers generiert werden. In einer Kammer auftretendes Leckagewasser kann somit nicht in die andere Kammer gelangen und dort angeordnete Komponenten benetzen und gegebenenfalls in ihrer Funktionalität beeinträchtigen.Preferably, the housing comprises a first chamber in which the end of the external water supply line is arranged. Furthermore, the housing preferably comprises a second chamber, in which the safety valve is arranged at least in regions. By means of such a chamber system in the housing, it is also possible to generate a sealing system with regard to leakage water leakage. Leakage water occurring in one chamber can thus not get into the other chamber and moisten components arranged there and possibly impair their functionality.
Vorzugsweise sind die beiden Kammern durch eine Trennwand separiert, in welcher eine Verbindungsöffnung ausgebildet ist. In dieser Verbindungsöffnung ist vorzugsweise das Sicherheitsventil eingesetzt. Insbesondere ist vorgesehen, dass das Sicherheitsventil passgenau in der Verbindungsöffnung angeordnet ist und diese Verbindungsöffnung durch den Einsatz des Sicherheitsventils ohne ein zusätzliches Dichtelement abgedichtet ist. Somit wird durch ein derartiges Zweikammeranschlussgehäuse und einer entsprechend großen Öffnung zur Abführung von Leckagewasser eine ausreichende Dichtfunktion in das Anschlussgehäuse integriert. Durch die Integration der Leckagewasserableitung wird auch eine gezielte Abführung einer derartigen Wasserbildung erreicht.Preferably, the two chambers are separated by a partition, in which a connection opening is formed. In this connection opening, the safety valve is preferably used. In particular, it is provided that the safety valve is arranged precisely in the connection opening and this connection opening is sealed by the use of the safety valve without an additional sealing element. Thus, a sufficient sealing function is integrated into the connection housing by such a two-chamber connection housing and a correspondingly large opening for the removal of leakage water. Through the integration of the leakage water discharge and a targeted discharge of such water formation is achieved.
Durch diese passgenaue Anordnung des Sicherheitsventils in die Verbindungsöffnung kann somit auch ein zusätzliches Dichtelement eingespart werden. Beide Kammern münden vorzugsweise separat in die Leckageöffnung und insbesondere erstreckt sich die Trennwand auch in die Leckageöffnung hinein. Dadurch kann das in einer Kammer auftretende Leckagewasser sicher und zuverlässig abgeführt werden ohne dass es in die andere Kammer gelangen kann. Bevorzugt mündet die Leckageöffnung seitlich aus dem Gehäuse. Insbesondere ist die Leckageöffnung in einem Gehäuseunter- teil integriert und mündet seitlich aus diesem Gehäuseunterteil. Insbesondere ist vorgesehen, dass die Leckageöffnung ein rohrartiger Stutzen ist. Durch diese Ausgestaltung kann das Leckagewasser zuverlässig und zielgeführt aus dem Gehäuse abgeführt werden. Ein zusätzlicher Leckagewasserschlauch ist nicht mehr erforderlich.As a result of this precisely fitting arrangement of the safety valve in the connection opening, it is thus also possible to save an additional sealing element. Both chambers preferably open separately into the leakage opening and, in particular, the dividing wall also extends into the leakage opening. As a result, the leakage water occurring in a chamber can be safely and reliably removed without it being able to get into the other chamber. Preferably, the leakage opening opens laterally out of the housing. In particular, the leakage opening is integrated in a housing lower part and opens laterally out of this housing lower part. In particular, it is provided that the leakage opening is a tube-like nozzle. With this configuration, the leakage water can be reliably and effectively removed from the housing. An additional leakage water hose is no longer required.
Durch die Kammerbildung in der Gehäusevorrichtung wird insbesondere verhindert, dass das Leckagewasser zu den elektrischen Anschlüssen gelangt. Dies kann insbesondere auch dann verhindert werden, wenn das Volumen der ersten Kammer, in der das Ende der externen Wasserzuführleitung angeordnet ist, nicht ausreichend sein sollte.The formation of a chamber in the housing device prevents, in particular, the leakage water from reaching the electrical connections. This can be prevented in particular even if the volume of the first chamber, in which the end of the external water supply is arranged, should not be sufficient.
Vorzugsweise ist die Vorrichtung als vormontierte Baugruppe ausgebildet und als Gesamtsystem zur Montage in dem Hausgerät bereitgestellt. Vorzugsweise kann somit der Zulaufschlauch und das Sicherheitsventil vormontiert und in ein zweiteiliges Gehäuse, mit einem Gehäuseoberteil und einem Gehäuseunterteil, eingelegt und dieses verschlossen werden. Durch dieses vollständig vormontierte Modul kann die Endmontage vereinfacht und auch schneller ermöglicht werden. Darüber hinaus kann eine Kostenreduzierung einerseits durch eine Bauteilreduzierung und der Baugruppenvormontage erreicht werden. Dadurch kann auch eine Kostenersparnis durch die schnellere Endmontage dieses vormontierten Moduls ermöglicht werden. Insbesondere kann auch ein einheitlicher Geräte- anschluss für verschiedene Geräte ermöglicht und ein einheitlicher Geräteanschluss für den Aqua-Stop-Zulaufschlauch ausgebildet werden.Preferably, the device is designed as a preassembled module and provided as an overall system for mounting in the household appliance. Preferably, therefore, the inlet hose and the safety valve can be preassembled and inserted into a two-part housing, with an upper housing part and a lower housing part, and this be closed. This completely pre-assembled module makes final assembly easier and faster. In addition, a cost reduction can be achieved on the one hand by a component reduction and the assembly pre-assembly. As a result, a cost savings through the faster final assembly of this preassembled module can be made possible. In particular, a uniform device connection for various devices can be made possible and a uniform device connection for the aqua-stop supply hose can be formed.
Neben einer Einsparung eines Leckagewasserschlauchs kann auch eine Verkürzung der Zulauflänge bei flexibler Schlauchverlegung außerhalb des Geräts erreicht werden.In addition to saving a leakage water hose, a shortening of the inflow length can be achieved with flexible hose routing outside of the device.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand schematischer Zeichnungen näher erläutert. Es zeigen:An embodiment of the invention will be explained in more detail with reference to schematic drawings. Show it:
Fig. 1 eine perspektivische Darstellung einer erfindungsgemäßen Vorrichtung; und Fig. 2 eine perspektivische Darstellung einer in einer Waschmaschine montierten erfindungsgemäßen Vorrichtung.Fig. 1 is a perspective view of a device according to the invention; and Fig. 2 is a perspective view of a device mounted in a washing machine according to the invention.
In den Figuren werden gleiche oder funktionsgleiche Elemente mit den gleichen Bezugs- zeichen versehen.In the figures, identical or functionally identical elements are provided with the same reference numerals.
In Fig. 1 ist ein Ausführungsbeispiel einer Vorrichtung 1 gezeigt, welche zur Verbindung einer externen Wasserzuführung mit einer internen Wasserführung einer mit Aqua-Stop- Funktionalität ausgeführten Waschmaschine ausgebildet ist. Die Vorrichtung 1 umfasst ein Gehäuse, welches ein Gehäuseunterteil 2 aufweist. In dem Gehäuse ist eine erste Kammer 3 sowie eine zweite Kammer 4 ausgebildet. Ein Sicherheitsventil 5 der Vorrichtung 1 ist mit einem Ventilkörper 6 zumindest bereichsweise in der zweiten Kammer 4 angeordnet. Der Ventilkörper 6 sitzt dichtungselementfrei in dem Gehäuse und ist insbesondere in einer Verbindungsöffnung 10 zwischen den Kammern 3 und 4 ohne zusätzli- ches Dichtungselement, aber dennoch diese Verbindungsöffnung 10 abdichtend, angeordnet. Diese Verbindungsöffnung 10 ist in einer Trennwand 10a ausgebildet, welche die Kammern 3 und 4 separiert.In Fig. 1, an embodiment of a device 1 is shown, which is designed to connect an external water supply to an internal water supply of a running with Aqua Stop functionality washing machine. The device 1 comprises a housing which has a housing lower part 2. In the housing, a first chamber 3 and a second chamber 4 is formed. A safety valve 5 of the device 1 is arranged with a valve body 6 at least partially in the second chamber 4. The valve body 6 sits sealing element-free in the housing and is in particular in a connection opening 10 between the chambers 3 and 4 without additional sealing element, but still sealingly arranged this connection opening 10. This connection opening 10 is formed in a partition wall 10 a, which separates the chambers 3 and 4.
An dem Ventilkörper 6 sind zwei Anschlüsse 1 1 und 12 ausgebildet, welche zwei separate Anschlüsse für Schläuche der internen Wasserführung der Waschmaschine darstellen.On the valve body 6, two terminals 1 1 and 12 are formed, which constitute two separate connections for hoses of the internal water flow of the washing machine.
In das Gehäuse der Vorrichtung 1 mündet ein Ende einer externen Wasserzuführleitung, welche einen Wasserschlauch 7 und einen Mantelschlauch 8 umfasst. Diese externe Zuführleitung führt zu einer externen Wasserquelle 9, welche die Hauswasserversorgung sein kann.In the housing of the device 1 opens one end of an external water supply, which comprises a water hose 7 and a jacket tube 8. This external supply line leads to an external water source 9, which may be the domestic water supply.
In dem Gehäuseunterteil 2 ist des Weiteren eine Öffnung 13 zur Abführung von Leckagewasser ausgebildet. Diese Leckageöffnung 13 ist vollständig in das Gehäuseunterteil 2 integriert und mündet seitlich aus dem Gehäuseunterteil 2 heraus.In the lower housing part 2, an opening 13 is further formed for the discharge of leakage water. This leakage opening 13 is completely integrated into the lower housing part 2 and opens laterally out of the lower housing part 2.
Diese Öffnung 13 ist als rohrartiger Stutzen ausgebildet und so angeordnet, dass beide Kammern 3 und 4 in die Öffnung 13 münden. Darüber hinaus ist zu erkennen, dass die Trennwand 10a auch innerhalb dieser Öffnung 13 ausgebildet ist und somit die Kammern 3 und 4 auch innerhalb dieses rohrartigen Stutzens separiert.This opening 13 is formed as a tubular nozzle and arranged so that both chambers 3 and 4 open into the opening 13. In addition, it can be seen that the Partition 10a is also formed within this opening 13 and thus the chambers 3 and 4 also separated within this tubular neck.
Um ventilseitig und somit im Bereich der zweiten Kammer 4 einen Wasseraustritt zu verhindern, wird das dort gegebenenfalls auftretende Leckagewasser über diese seitliche Öffnung 13 abgeführt. Ebenso kann bei einer Undichtigkeit im Wasserzulaufbereich und somit im Bereich der ersten Kammer 3 das gegebenenfalls auftretende Leckagewasser gezielt ins Innere der Waschmaschine abgeführt werden und gelangt über die Innenseite einer Seitenwand 14 (Fig. 2) und einer im Bereich der Bodengruppe der Waschmaschine ausgebildeten Auffangrinne zu einem nicht dargestellten Schwimmerschalter.In order to prevent leakage of water on the valve side and thus in the region of the second chamber 4, the leakage water which may possibly occur there is removed via this lateral opening 13. Likewise, in the event of a leak in the water inlet region and thus in the region of the first chamber 3, any leakage water that occurs may be deliberately removed into the interior of the washing machine and arrives via the inside of a side wall 14 (FIG. 2) and a collecting channel formed in the region of the bottom group of the washing machine a float switch, not shown.
Bei dem vorgeschlagenen System sind somit das Sicherheitsventil 5 bzw. der Ventilkörper 6 und das Wasserleitsystem in einem Gehäuse verbunden. Insbesondere ist die Vorrichtung 1 als vollständig vormontierte Baugruppe bereitgestellt, wobei dazu zunächst der Wasserschlauch 7, der Mantelschlauch 8 und das Sicherheitsventil 5 mit dem Ventilkörper 6 bereichsweise in das Gehäuse entsprechend eingelegt werden und dieses Gehäuse verschlossen wird. Dazu wird dann das in Fig. 2 gezeigte Gehäuseoberteil 15 mit dem Gehäuseunterteil 2 verbunden. Beispielsweise kann eine Verschraubung oder aber auch ein Verrasten oder dergleichen vorgesehen sein. Das dann so bereitgestellte und vormontierte Modul kann dann nachträglich in aufwandsarmer und schneller Weise in dem Haus- gerät endmontiert werden. In the proposed system, therefore, the safety valve 5 and the valve body 6 and the water supply system are connected in a housing. In particular, the device 1 is provided as a completely preassembled subassembly, for which purpose firstly the water hose 7, the jacket hose 8 and the safety valve 5 with the valve body 6 are inserted in certain areas into the housing and this housing is closed. For this purpose, the upper housing part 15 shown in FIG. 2 is then connected to the lower housing part 2. For example, a screw connection or even a latching or the like may be provided. The pre-assembled module, which is then provided, can then be subsequently assembled in the household appliance in a time-consuming and quick manner.
