Description

Wasserführendes Hausgerät mit einer Wasservorlageeinrichtung  Water-carrying household appliance with a water supply device
Die Erfindung betrifft ein wasserführendes Hausgerät, insbesondere ein Wäschebehandlungsgerät zum Waschen und Trocknen von Wäsche. Speziell betrifft die Erfindung das Gebiet der Waschtrockner, bei denen die Funktion des Waschens und Trocknens in einem Gerät integriert sind. The invention relates to a water-conducting household appliance, in particular a laundry treatment appliance for washing and drying laundry. Specifically, the invention relates to the field of laundry dryers in which the function of washing and drying are integrated in one device.
Bei einem Waschtrockner kann während eines Waschvorgangs Frischwasser, das gegebenenfalls Wäschebehandlungsmittel mitführt, über einen Zulaufstrang in einen Laugenbehälter geführt werden. Dabei besteht das Problem, dass während eines Wasch- oder Trocknungsgangs Dampf über den Zulaufstrang austreten kann. In a washer-dryer, during a washing process, fresh water, which optionally carries laundry treatment agent, can be led via a feed line into a suds container. There is the problem that during a washing or drying cycle steam can escape via the intake line.
Denkbar ist es, dass in den Zulaufstrang ein gebogenes Rohrstück integriert wird, das eine gewisse Menge an Wasser aufnimmt, wodurch eine Dampfsperre gebildet ist. Solch eine Dampfsperre hat allerdings den Nachteil, dass durch Erschütterungen oder dergleichen Wasser überschwappt, wodurch während des Trocknungsvorgangs Wasser in den Behandlungsbereich gelangt. It is conceivable that in the inlet strand a bent pipe section is integrated, which absorbs a certain amount of water, whereby a vapor barrier is formed. However, such a vapor barrier has the disadvantage that spills over by vibrations or the like water, whereby water enters the treatment area during the drying process.
Aufgabe der Erfindung ist es, ein wasserführendes Hausgerät zu schaffen, das einen verbesserten Aufbau aufweist. Speziell ist es eine Aufgabe der Erfindung, ein wasserführendes Hausgerät anzugeben, bei dem eine vorteilhafte Dampfsperre verwirklicht ist. Eine weitere Aufgabe der Erfindung ist es, ein wasserführendes Hausgerät zu schaffen, bei dem eine zuverlässige Dampfsperre für den Behandlungsbereich geschaffen ist, wobei ein unerwünschter Eintrag von Wasser aus der Dampfsperre in den Behandlungsbereich verhindert ist. The object of the invention is to provide a water-conducting domestic appliance, which has an improved structure. Specifically, it is an object of the invention to provide a water-conducting household appliance, in which an advantageous vapor barrier is realized. A further object of the invention is to provide a water-conducting household appliance, in which a reliable vapor barrier is provided for the treatment area, wherein an undesirable entry of water from the vapor barrier is prevented in the treatment area.
Die Aufgabe wird durch ein wasserführendes Hausgerät, insbesondere ein Wäschebehandlungsgerät zum Waschen und Trocknen von Wäsche, gelöst, bei dem ein Behandlungsbereich, der zumindest eine Zulaufstelle aufweist, und eine Wasservorlageeinrichtung vorgesehen sind, die zumindest mittelbar mit der Zulaufstelle des Behandlungsbereichs verbunden ist, wobei die Wasservorlageeinrichtung einen Saugheber aufweist. Durch die in den abhängigen Patentansprüchen sowie nachfolgender Beschreibung aufgeführten Maßnahmen sind bevorzugte und vorteilhafte Weiterbildungen des erfindungsgemäßen wasserführenden Hausgeräts möglich. The object is achieved by a water-conducting domestic appliance, in particular a laundry treatment appliance for washing and drying laundry, in which a treatment area having at least one inlet point, and a water supply device are provided, which is at least indirectly connected to the feed point of the treatment area, wherein the Water supply device has a siphon. The measures listed in the dependent claims and the following description, preferred and advantageous developments of the water-conducting household appliance according to the invention are possible.
Vorteilhaft ist es, dass der Saugheber durch einen Saugheberkanal gebildet ist. Ferner ist es vorteilhaft, dass die Wasservorlageeinrichtung zumindest ein gebogenes Rohrstück aufweist und dass der Saugheberkanal in das gebogene Rohrstück der Wasservorlageeinrichtung integriert ist. Während des Zuführens von Wasser in den Behandlungsbereich wird das gebogene Rohrstück zusammen mit dem Saugheberkanal von dem zugeführten Wasser durchspült. Wenn die Zufuhr von Wasser unterbrochen wird, dann senkt der Saugheber ein Wasserniveau in der Wasservorlageeinrichtung ab. Dadurch kann das Niveau der Wasservorlage vorgegeben werden. Hierdurch kann zum einen eine ausreichende Menge an Wasser in der Wasservorlageeinrichtung verbleiben, um eine zuverlässige Dampfsperre für einen Wasch- und/oder Trocknungsgang zu bilden. Zum anderen wird ein unerwünschtes Abfließen von Wasser aus der Wasservorlageeinrichtung verhindert. Dies gewährleistet ein konstantes Wasserniveau der Wasservorlage in der Wasservorlageeinrichtung, so dass auch beim Auftreten von Erschütterungen oder dergleichen die Funktion der Dampfsperre erhalten bleibt. Außerdem wird verhindert, dass beispielsweise beim Öffnen der Tür des wasserführenden Hausgeräts oder dergleichen Wasser aufgrund des Druckausgleichs aus der Wasservorlageeinrichtung austritt und in den Behandlungsbereich gelangt. Hierdurch kann ein Benetzen von Wäsche oder dergleichen sowie ein von dem Benutzer gegebenenfalls wahrnehmbares Wasserrinnsal verhindert werden. Ferner kann auch während des Betriebs, insbesondere bei einem Trocknungsvorgang, ein Austreten von Wasser aus der Wasservorlageeinrichtung in den Behandlungsbereich verhindert werden. It is advantageous that the siphon is formed by a siphon channel. Furthermore, it is advantageous that the water supply device has at least one curved pipe section and that the siphon channel is integrated into the curved pipe section of the water supply device. During the supply of water into the treatment area, the bent pipe section is flushed through by the supplied water together with the siphon channel. When the supply of water is interrupted, the siphon lowers a water level in the water supply device. This allows you to set the level of the water template. In this way, on the one hand, a sufficient amount of water in the water supply device remain to form a reliable vapor barrier for a washing and / or drying cycle. On the other hand, an undesirable outflow of water from the water supply device is prevented. This ensures a constant water level of the water reservoir in the water supply device, so that the function of the vapor barrier is maintained even when vibrations or the like occur. In addition, it is prevented that, for example, when opening the door of the water-bearing household appliance or the like water exits due to the pressure equalization of the water supply device and enters the treatment area. As a result, wetting of laundry or the like as well as a water trough which may possibly be perceived by the user can be prevented. Furthermore, even during operation, in particular during a drying process, leakage of water from the water supply device into the treatment area can be prevented.
Vorteilhaft ist es, dass die Wasservorlageeinrichtung einen Vorlagenabschnitt und einen oberen Bogenabschnitt, der über dem Vorlagenabschnitt angeordnet ist, aufweist und dass eine Saugseite des Saughebers unter einem Überlaufniveau des Bogenabschnitts in den Vorlagenabschnitt mündet. Ferner ist es vorteilhaft, dass der Vorlagenabschnitt durch ein gebogenes Rohrstück gebildet ist und/oder dass der obere Bogenabschnitt durch ein gebogenes Rohrstück gebildet ist. Dadurch ist während des Einspülens von Wasser in den Behandlungsbereich eine vorteilhafte Führung des Wasserstroms, der gegebenenfalls Wäschebehandlungsmittel oder dergleichen mitnimmt, gewährleistet. Die Wasservorlageeinrichtung kann ein oder mehrteilig, insbesondere zweiteilig, ausgestaltet sein. Speziell ist es vorteilhaft, dass der Vorlagenabschnitt aus einem Weichmaterial, insbesondere einem weichen Kunststoff, gebildet ist und/oder dass der obere Bogenabschnitt aus einem Hartmaterial, insbesondere einem harten Kunststoff, gebildet ist. Speziell wenn der Saugheber als Saugheberkanal oder dergleichen in den oberen Bogenabschnitt integriert ist, dann wird durch die Ausgestaltung des oberen Bogenabschnitts mit dem Saugheberkanal aus dem Hartmaterial eine zuverlässige Funktionsweise der Wasservorlageeinrichtung gewährleistet. Durch die Ausgestaltung des Vorlagenabschnitts aus dem Weichmaterial kann ein gewisser Ausgleich gegenüber Erschütterungen oder dergleichen und eine einfachere Montage gewährleistet werden. It is advantageous that the water supply device has a master section and an upper arc section, which is arranged above the master section, and that a suction side of the suction lifter opens into the master section under an overflow level of the curved section. Further, it is advantageous that the template portion is formed by a bent pipe piece and / or that the upper arc portion is formed by a bent pipe section. As a result, during the flushing of water into the treatment area, an advantageous guidance of the water flow, which optionally entrains laundry treatment means or the like, is ensured. The Water supply device may be one or more parts, in particular two parts, configured. Specifically, it is advantageous that the template portion of a soft material, in particular a soft plastic, is formed and / or that the upper arc portion of a hard material, in particular a hard plastic, is formed. Specifically, if the siphon is integrated as Saugheberkanal or the like in the upper arc portion, then the design of the upper arc portion with the Saugheberkanal from the hard material ensures reliable operation of the water supply device. Due to the design of the template section of the soft material, a certain balance against vibration or the like and a simpler installation can be ensured.
Vorteilhaft ist es auch, dass ein Zulaufniveau eines Eingangs des Vorlagenabschnitts höher als die Saugseite des Saughebers angeordnet ist. Dadurch nimmt der Vorlagenabschnitt der Wasservorlageeinrichtung die gespeicherte Wassermenge vollständig auf, wobei das Wasserniveau der Wasservorlage nicht über eine Anschlussstelle oder dergleichen am Eingang des Vorlagenabschnitts hinaussteht. Hierdurch wird auch beim Auftreten von Erschütterungen oder dergleichen über die Lebensdauer das Auftreten einer unerwünschten Leckstelle von vornherein verhindert. Außerdem ist hierdurch die Menge des gespeicherten Wassers unabhängig von den Anschlussgegebenheiten. It is also advantageous that an inlet level of an inlet of the master section is arranged higher than the suction side of the siphon. As a result, the master portion of the water supply means completely absorbs the stored amount of water, and the water level of the water supply does not protrude beyond a junction or the like at the entrance of the original portion. As a result, the occurrence of shocks or the like over the life of the occurrence of an undesirable leak is prevented from the outset. In addition, this is the amount of stored water regardless of the connection conditions.
In vorteilhafter Weise ist der Behandlungsbereich von einem Behälter umgeben, wobei eine mit dem Behälter verbundene, flexible Manschette vorgesehen ist, wobei die Zulaufstelle des Behandlungsbereichs an der flexiblen Manschette vorgesehen ist und wobei die Wasservorlageeinrichtung direkt oder mittels eines Rohrstücks an der Zulaufstelle mit der flexiblen Manschette verbunden ist. Hierdurch kann die Übertragung von Erschütterungen oder dergleichen von der Trommel auf die Wasservorlageeinrichtung weiter gedämpft werden. Außerdem vereinfacht sich die Montage. Advantageously, the treatment area is surrounded by a container, wherein a flexible sleeve connected to the container is provided, wherein the feed point of the treatment area is provided on the flexible sleeve and wherein the water supply device directly or by means of a piece of pipe at the inlet point with the flexible sleeve connected is. As a result, the transmission of vibrations or the like from the drum to the water supply device can be further damped. In addition, the assembly is simplified.
Vorteilhaft ist es auch, dass die Wasservorlageeinrichtung in einem Zulaufstrang angeordnet ist, über den Frischwasser in den Behandlungsbereich führbar ist. Je nach Programmablauf kann das Frischwasser hierbei auch ein oder mehrere Behandlungsmittel in den Behandlungsbereich spülen. Die Wasservorlageeinrichtung kann allerdings auch an einer anderen Stelle des wasserführenden Hausgeräts angeordnet sein, um eine zuverlässige Dampfsperre zu bilden. It is also advantageous that the water supply device is arranged in a supply line, via the fresh water in the treatment area can be guided. Depending on the program sequence, the fresh water can also flush one or more treatment agents into the treatment area. The water supply device However, it may also be located elsewhere in the water-bearing household appliance to form a reliable vapor barrier.

In this case, a feed point 16 is provided on the sleeve 15, which serves as a feed point 16 for the treatment area 3. The pipe section 12 opens at the feed point 16 in the treatment area 3. Thus, fresh water and optionally a mixture of fresh water and a laundry treatment agent in the treatment area 3 can be performed on the feed line 4.
Das wasserführende Hausgerät 1 weist außerdem einen Abpumpstrang 17 auf, der eine Verschlussklappe 18, eine Laugenpumpe 19 und eine Leitung 20 umfasst. Bei geöffneter Verschlussklappe 18 kann die in dem Behälter 2 vorgesehene Lauge durch Betätigen der Laugenpumpe 19 über die Leitung 20 zu einem Ausgang 21 gepumpt werden. Der Ausgang 21 kann hierbei mit einem geeigneten Abfluss einer Hausinstallation oder dergleichen verbunden werden. The water-bearing domestic appliance 1 also has a pumping line 17 which comprises a closure flap 18, a drain pump 19 and a line 20. When the closure flap 18 is open, the liquor provided in the container 2 can be pumped via the line 20 to an outlet 21 by actuating the drain pump 19. The output 21 can in this case be connected to a suitable outflow of a domestic installation or the like.
Die Wasservorlageeinrichtung 10 weist einen Vorlagenabschnitt 22 und einen oberen Bogenabschnitt 23 auf. Der obere Bogenabschnitt 23 ist an einer Verbindungsstelle 24 mit dem Vorlagenabschnitt 22 verbunden, wobei der obere Bogenabschnitt 23 an der Verbindungsstelle 24 über dem Vorlagenabschnitt 22 angeordnet ist. Der Vorlagenabschnitt 22 ist durch ein gebogenes Rohrstück 25 gebildet. Außerdem ist der obere Bogenabschnitt 23 durch ein gebogenes Rohrstück 26 gebildet. Hierbei ist das gebogene Rohrstück 25 aus einem Weichmaterial gebildet. Das gebogene Rohrstück 26 ist aus einem Hartmaterial gebildet. Das aus dem Hartmaterial gebildete gebogene Rohrstück 26 weist einen Saugheber 27 auf. In diesem Ausführungsbeispiel ist der Saugheber 27 durch einen Saugheberkanal 28 gebildet, der neben einem Durchlaufkanal 29 in dem gebogenen Rohrstück 26 des oberen Bogenabschnitts 23 ausgestaltet ist. Der Saugheber 27 weist eine Saugseite 30 und einen Auslass 31 auf. Dabei ist der Auslass 31 des Saughebers 27 unter der Saugseite 30 angeordnet. Durch die Saugseite 30 des Saughebers 27 ist ein Vorlagenniveau 32 vorgegeben. The water supply device 10 has a master section 22 and an upper arch section 23. The upper arcuate portion 23 is connected at a junction 24 to the master portion 22 with the upper arcuate portion 23 disposed at the junction 24 above the master portion 22. The master section 22 is formed by a bent pipe section 25. In addition, the upper arc portion 23 is formed by a bent pipe section 26. Here, the bent pipe section 25 is formed of a soft material. The bent pipe piece 26 is formed of a hard material. The curved formed from the hard material Pipe piece 26 has a siphon 27. In this embodiment, the siphon 27 is formed by a siphon channel 28, which is configured next to a passage channel 29 in the bent pipe section 26 of the upper arc portion 23. The siphon 27 has a suction side 30 and an outlet 31. In this case, the outlet 31 of the siphon 27 is arranged below the suction side 30. Through the suction side 30 of the siphon 27 a template level 32 is specified.
Wenn die Wasservorlageeinrichtung 10 mit Frischwasser durchspült wird, dann strömt das Frischwasser sowohl durch den Durchlaufkanal 29 als auch durch den Saugheberkanal 28 des gebogenen Rohrstücks 26. Wenn die Frischwasserzufuhr unterbrochen wird, dann wird über den Saugheberkanal 28 Wasser aus dem Vorlagenabschnitt 22 angesaugt, bis der Wasserpegel das Vorlagenniveau 32 erreicht. Das Vorlagenniveau 32 liegt unterhalb eines Überlaufniveaus 33, ab dem Wasser durch den Durchlaufkanal 29 in den Behandlungsbereich 3 fließt. Außerdem liegt das Vorlagenniveau 32 unterhalb des Eingangs 1 1 des Vorlagenabschnitts 22. When the water supply device 10 is flushed with fresh water, then the fresh water flows through both the flow channel 29 and the siphon channel 28 of the bent pipe section 26. When the fresh water supply is interrupted, then water is sucked from the master section 22 via the siphon channel 28 until the Water level reaches the template level 32. The original level 32 is below an overflow level 33, from which water flows through the flow channel 29 into the treatment area 3. In addition, the original level 32 is below the input 1 1 of the master section 22nd
Während eines Wasch- oder Trockenvorgangs bildet die in dem Vorlagenabschnitt 22 bis zum Vorlagenniveau 32 mit Wasser gefüllte Wasservorlageeinrichtung 10 eine Dampfsperre. Wenn aufgrund von Erschütterungen oder dergleichen das Wasser im Vorlagenabschnitt 22 in Bewegungen versetzt wird, dann wird ein Herausschwappen von Wasser zuverlässig verhindert, da das Vorlagenniveau 32 deutlich niedriger als das Überlaufniveau 33 ist. Somit bleibt die Funktionsfähigkeit der Dampfsperre gewährleistet. Außerdem wird verhindert, dass Wasser aufgrund solcher Bewegungen über das Rohrstück 12 in den Behandlungsbereich 3 fließt. Außerdem kann es beim Öffnen des Behälters 2 aufgrund des Druckausgleichs zu einer gewissen Bewegung des Wassers im Vorlagenabschnitt 22 kommen. Auch bei diesen Bewegungen ist ein Abfließen von Wasser in den Behandlungsbereich 3 verhindert. During a washing or drying operation, the water supply device 10 filled with water in the master section 22 to the original level 32 forms a vapor barrier. If, due to vibrations or the like, the water in the master section 22 is set in motion, then a sloshing of water is reliably prevented because the master level 32 is significantly lower than the overflow level 33. Thus, the functionality of the vapor barrier remains guaranteed. In addition, it is prevented that water flows through the pipe section 12 in the treatment area 3 due to such movements. In addition, there may be some movement of the water in the master section 22 when opening the container 2 due to the pressure equalization. Even with these movements, a flow of water into the treatment area 3 is prevented.
Somit verbleibt das nach dem Einspülen bis zum Vorlagenniveau 32 in der Wasservorlageeinrichtung 10 stehende Wasser zuverlässig in dem Vorlagenabschnitt 22. Je nach Ausgestaltung der Wasservorlageeinrichtung 10 kann der Ausgang 13 auch direkt mit der Zulaufstelle 16 des Behandlungsbereichs 3 verbunden sein. Speziell kann der Ausgang 13 an der Zulaufstelle 16 mit der Manschette 15 verbunden sein. Somit kann das wasserführende Hausgerät 1 eine prozesssichere Manschettenbespülung durch den Zulaufstrang 4 aufweisen, die einen Dampfaustritt aus dem Laugenbehälter 2 während des Wasch- und Trocknungsvorgangs, eines Thermoscheuderns oder dergleichen verhindert und zugleich das Überschwappen von überschüssigem Wasser aus der Wasservorlageeinrichtung 10 beim Öffnen einer Tür, die mit dem Behälter 2 verbunden ist, vermeidet. Hierbei kann eine zumindest näherungsweise hermetische Abschließung des Behandlungsbereichs 3 erzielt werden. Die Wasservorlageeinrichtung 10 übernimmt hierbei den Verschluss auf der Seite des Zulaufstrangs 4. Die Wasservorlageeinrichtung 10 kann dabei ein relativ großes Wasservolumen zum Bilden einer Dampfsperre aufnehmen. Durch den Saugheber 27 ist die Wassermenge und das Vorlagenniveau 32 der Wassermenge vorgegeben. Speziell kann eine unerwünschte Benetzung einer getrockneten Wäsche zuverlässig vermieden werden. Thus, the water remaining in the water supply device 10 after flushing up to the original level 32 reliably remains in the master section 22. Depending on the configuration of the water supply device 10, the outlet 13 can also be connected directly to the feed point 16 of the treatment area 3. Specifically, the outlet 13 may be connected to the cuff 15 at the feed point 16. Thus, the water-bearing domestic appliance 1 may have a process-safe cuff flushing through the inlet string 4, which prevents vapor leakage from the tub 2 during the washing and drying process, a thermal washer or the like and at the same time spilling excess water from the water supply device 10 when opening a door, which is connected to the container 2, avoids. In this case, an at least approximately hermetic closure of the treatment area 3 can be achieved. The water supply device 10 takes over the closure on the side of the intake line 4. The water supply device 10 can receive a relatively large volume of water to form a vapor barrier. By the siphon 27, the amount of water and the template level 32 of the amount of water is specified. In particular, unwanted wetting of a dried laundry can be reliably avoided.
Die Wasservorlageeinrichtung 10 kann auch einteilig ausgestaltet sein. Vorteilhaft ist allerdings eine mehrteilige, insbesondere zweiteilige, Ausgestaltung, wobei in vorteilhafter Weise eine Kombination eines Weichmaterials und eines Hartmaterials zum Einsatz kommen kann. Hierbei können die beiden Teile, nämlich der Vorlagenabschnitt 22 und der obere Bogenabschnitt 23, an der Verbindungsstelle 24 durch Ineinanderstecken miteinander verbunden werden. Beispielsweise kann das gebogene Rohrstück 25 aus einem Weichmaterial, insbesondere Gummi oder EPDM, gebildet sein. The water supply device 10 may also be configured in one piece. However, a multi-part, in particular two-part, embodiment is advantageous, wherein advantageously a combination of a soft material and a hard material can be used. Here, the two parts, namely the master section 22 and the upper arc section 23, are connected to each other at the connection point 24 by nesting. For example, the bent pipe section 25 may be formed of a soft material, in particular rubber or EPDM.
Der Saugheberkanal 28 weist vorzugsweise einen relativ kleinen Durchmesser auf. Die Weiterleitung von Frischwasser und gegebenenfalls in dem Frischwasser mitgeführten Behandlungsmitteln kann im Wesentlichen über den Durchlaufkanal 29 erfolgen. Dadurch kann eine ausreichende Durchflussrate erzielt werden. Somit kann das Auftreten eines Leckagewassers im Bereich der Zulaufstelle 16 der flexiblen Manschette 15, insbesondere beim Öffnen des Türkomplexes, vermieden werden. Außerdem ist eine Nachbefeuchtung der Wäsche beim Öffnen des Fensterkomplexes verhindert, da eine prozesssichere Wasservorlage durch die Wasserstandsregulierung mittels des Saughebers 27 gewährleistet ist. Hierbei kann eine Platz sparende Bauraumanordnung und eine kompakte Bauform realisiert werden. Somit ist eine vorteilhafte und zuverlässige Dampfsperre für den Laugenbehälter oder einen anderen Behälter 2 gegeben. BezugszeichenlisteThe siphon channel 28 preferably has a relatively small diameter. The forwarding of fresh water and possibly in the fresh water entrained treatment agents can be carried out substantially via the passage channel 29. This allows a sufficient flow rate can be achieved. Thus, the occurrence of leakage water in the area of the feed point 16 of the flexible sleeve 15, in particular when opening the door complex, can be avoided. In addition, a Nachbefeuchtung the laundry when opening the window complex is prevented because a process-safe water mask is ensured by the water level control by means of the siphon 27. Here, a space-saving installation space and a compact design can be realized. Thus, an advantageous and reliable vapor barrier for the tub or other container 2 is given. LIST OF REFERENCE NUMBERS
