Abstract
Description
Die Erfindung geht aus von einer Haushalt-Waschmaschine mit Leitungen für die verteilt geschaltete Zuführung von Frischwasser, für die Abführung von gebrauchter Lauge und für die Führung von Druckausgleichs-Luft.The invention relates to a household washing machine with lines for the distributed switched supply of fresh water, for the discharge of used Alkali and for the guidance of pressure equalization air.
Derartige Waschmaschinen sind bekannt und gebräuchlich (DE 37 34 117 A1) und benutzen für die besagten Leitungen regelmäßig mehr oder weniger flexible Rohroder Schlauchabschnitte zur jeweiligen Verbindung von Stutzen an unterschiedlichen Orten in der Waschmaschine angeordneter Wasser- oder Luft-Behandlungseinrichtungen. So werden regelmäßig flexible Schlauchleitungen zwischen den Stutzen von elektrisch geschalteten Magnetventilen und den Einlaßstutzen einer Waschmittel-Einspüleinrichtung wie auch eine ebenfalls flexible Schlauchleitung vom Druckausgleichsstutzen eines Überlaufbogens an der Laugenablaufleitung mit einem entsprechenden Stutzen beispielsweise an der Waschmittel-Einspüleinrichtung zum Ausgleichen von Druckunterschieden benutzt. Ferner werden auch einzelne Steigleitungen aus flexiblen Schläuchen zwischen einer Laugenpumpe und einem zumeist aus Kunststoff hergestellten Überlaufbogen geführt und - sofern vorhanden - eine Falleitung vom Ablaufstutzen einer Waschmittel-Einspülschale zum Gehäuse der Laugenpumpe in Form einer flexiblen Schlauchleitung.Such washing machines are known and used (DE 37 34 117 A1) and regularly use more or less flexible pipe or pipe for the said pipes Hose sections for the respective connection of nozzles at different Locations of water or air treatment facilities located in the washing machine. For example, flexible hose lines between the nozzles of electrically switched solenoid valves and the inlet port of a detergent dispenser as well as an equally flexible hose line from the pressure compensation connection an overflow bend on the drain line with a corresponding one For example, sockets on the detergent dispenser to compensate used by pressure differences. Furthermore, individual risers mostly made of flexible hoses between a drain pump and one Plastic overflow bend and - if available - a downpipe from the drain socket of a detergent dispenser to the drain pump housing in the form of a flexible hose line.
Abgesehen von der verhältnismäßig teuren Herstellung jeweils besonderer Leitungsteile für die Frischwasserzuführung, den Druckluftausgleich und die Laugenabführung ist deren Lagerhaltung und gegebenenfalls logistische Behandlung zusätzlich zeit- und kostenintensiv. Ebenfalls zeit- und kostenintensiv ist die Montage all dieser Einzelteile im Fertigungsprozeß einer Waschmaschine.Apart from the relatively expensive manufacture of special line parts for fresh water supply, compressed air compensation and lye discharge is their storage and, if necessary, logistical treatment additional time and expensive. The assembly of all these individual parts is also time and cost intensive in the manufacturing process of a washing machine.
Der Erfindung liegt die Aufgabe zugrunde, bei einer eingangs beschriebenen Haushalt-Waschmaschine ein möglichst kostengünstiges System für die Wasserführung innerhalb der Waschmaschine anzugeben. Dabei soll darauf geachtet werden, daß die für das System benötigten Einzelteile zahlenmäßig und fertigungstechnisch geringste Aufwendungen erfordern.The invention has for its object in a household washing machine described above the most cost-effective system for water supply within the washing machine. It should be ensured that the for the system required individual parts in terms of numbers and manufacturing technology Require expenses.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zum Hinführen der Leitungen von ihren Zuleitungsorten zu ihren Ableitungsorten ein gemeinsamer Kunststoff-Leitungskörper vorgesehen ist, dessen Zuführungsleitungs-Mündungen über elastische Dichtungshülsen mit den Zu- und Ableitungsorten dichtend verbunden und mechanisch gehalten sind.According to the invention, this object is achieved in that for leading the lines a common plastic cable body from their supply points to their discharge points is provided, the feed line mouths via elastic Sealing sleeves sealingly connected to the supply and discharge locations and mechanically are held.
Die erfindungsgemäße Ausgestaltung einer Haushalt-Waschmaschine der eingangs genannten Art ermöglicht eine wesentliche Verringerung der Bauteilanzahl. Ferner entfallen diverse Halteelemente aufgrund der starren Konstruktion des Kunststoff-Leitungskörpers, der zwischen all den Leitungsmündungen über Dichtungshülsen mit starr innerhalb des Waschmaschinen-Gehäuses angeordneten Wasserbehandlungs-Baugruppen montiert ist.The inventive design of a household washing machine at the outset mentioned type enables a substantial reduction in the number of components. Further Various holding elements are eliminated due to the rigid construction of the plastic cable body, the between all the pipe openings with sealing sleeves Water treatment assemblies arranged rigidly within the washing machine housing is mounted.
Dadurch ergibt sich gleichzeitig eine vereinfachte Montage, weil alle Leitungsteile innerhalb des einen Kunststoff-Leitungskörpers zusammengefaßt sind und dadurch die Montage einzelner Schlauchteile mit jeweils zwei Schlauchschellen entbehrlich ist. Außerdem ergibt sich in dichtungstechnischer Hinsicht eine Qualitätsverbesserung, weil nicht mehr auf einen optimalen Sitz von Schellen an den Schlauchverbindungen geachtet werden muß. Die Montage des kompakten Leitungskörpers muß hingegen wegen der festen Abmessungen zwischen den zu verbindenden Baugruppen selbsttätig dichtend erfolgen. Schließlich läßt sich durch den Kunststoff-Leitungskörper eine einzige, aus recyclingfähigem Polypropylen bestehende Baugruppe als Ersatz für viele einzelne, aus unterschiedlichen Werkstoffen bestehende Bauteile verwenden.This results in a simplified assembly at the same time, because all line parts within of a plastic line body are summarized and thereby the Assembly of individual hose parts with two hose clamps is unnecessary. Moreover In terms of sealing technology, there is an improvement in quality because no longer paid attention to an optimal fit of clamps on the hose connections must become. The assembly of the compact line body, however, must be the fixed dimensions between the modules to be connected automatically sealing. Finally, a single, assembly made of recyclable polypropylene as a replacement for many use individual components made of different materials.
Gemäß einer vorteilhaften Ausführungsform der Erfindung sind die Leitungen für die Zuführung von Frischwasser eingangsseitig unmittelbar mit den Ausgängen von Magnetventilen verbunden. In diesem Zusammenhang vorteilhaft ist auch die unmittelbare ausgangsseitige Verbindung der Leitungen für die Zuführung von Frischwasser mit den Eingängen einer Waschmittel-Einspülschale. Dadurch lassen sich zumeist zwei oder drei einzelne Schlauchleitungen zwischen den Magnetventilen und der Waschmittel-Einspüleinrichtung zusammen mit ihren zur Abdichtung benötigten Schlauchschellen vermeiden.According to an advantageous embodiment of the invention, the lines for the Fresh water supply on the input side directly through the outputs of solenoid valves connected. The immediate one is also advantageous in this context output connection of the lines for the supply of fresh water with the inputs of a detergent dispenser. This usually allows two or three individual hose lines between the solenoid valves and the Detergent dispenser along with those needed for sealing Avoid hose clips.
In besonders vorteilhafter Weise enthält der Leitungskörper auch eine Leitung zur Führung von Überlaufwasser. Überlaufwasser kann beispielsweise über die Waschmittel-Einspüleinrichtung und von dort über eine gerichtete Ableitung zu einer Auffangwanne geführt werden, in der zur Überlaufsicherung niveausensorische Schalteinrichtungen angeordnet sind. Auch hierbei ist die unmittelbare Verbindung der Leitung zur Führung von Überlaufwasser eingangsseitig mit einem Überlaufstutzen der Waschmittel-Einspüleinrichtung von besonderem Vorteil.In a particularly advantageous manner, the line body also contains a line for guidance of overflow water. Overflow water can, for example, via the detergent dispenser and from there via a directional drain to a drip pan be guided in the level sensor switchgear for overflow protection are arranged. Here, too, is the direct connection between the line and the management of overflow water on the inlet side with an overflow nozzle of the detergent dispenser of particular advantage.
In besonders vorteilhafter Weise ist in den Leitungskörper auch eine Druckausgleichsleitung zum Führen von Druckausgleichs-Luft integrierbar, die eingangsseitig mit einem Entlüftungsstutzen der Waschmittel-Einspüleinrichtung und ausgangsseitig mit einem Überlaufbogen unmittelbar verbunden ist.A pressure compensation line is also particularly advantageous in the line body can be integrated to guide pressure equalization air, the input side with a Vent pipe of the detergent dispenser and on the outlet side with a Overflow bend is directly connected.
Den größten Vorteil bildet eine Weiterbildung der Erfindung, in der der Leitungskörper ein Steigrohr und ein Fallrohr für die Abführung der gebrauchten Lauge sowie einen diese beiden Rohre verbindenden Überlaufbogen enthält. Von besonderem Vorteil ist dabei, daß der Überlaufbogen an einen im Zuge des Steigrohrs liegenden Rücklaufbehälter für den Rückhalt einer zum Rückspülen benötigten Menge von Lauge angeschlossen ist. Die Integration der Laugenabführungsmittel in den Leitungskörper bietet gegenüber der Herstellung, der Logistik und der Montage von einzelnen Leitungsteilen und Schläuchen mit ihren Verbindungselementen den größten Vorteil bei der integralen Gestaltung des Leitungskörpers.The greatest advantage is a further development of the invention, in which the line body a standpipe and a downpipe for the discharge of the used lye and one contains these two pipes connecting overflow bend. Is of particular advantage thereby that the overflow bend to a return tank lying in the course of the riser pipe connected to retain an amount of lye required for backwashing is. The integration of lye laxatives into the line body offers compared to the manufacture, logistics and assembly of individual line parts and hoses with their connecting elements have the greatest advantage in the integral Design of the management body.
Fertigungstechnisch in einfacher Weise läßt sich der Leitungskörper dadurch gestalten, daß er aus einem Kunststoff-Blasteil geformt ist.In terms of production technology, the line body can be designed in a simple manner by that it is molded from a plastic blow molded part.
Für die Montage eines solchen Leitungskörpers ist es von besonderem Vorteil, wenn an den Leitungskörper mindestens eine Lasche zum provisorischen Halten des Leitungskörpers vor der Montage der Leitungsverbindungen angeformt ist. Solche Laschen können zum provisorischen Halten des Leitungskörpers über hierfür vorgesehene Kanten oder Schlitze in Gehäuseteilen der Waschmaschine gehängt werden.For the assembly of such a line body, it is particularly advantageous if at least one tab on the lead body for provisionally holding the lead body is molded on before installing the cable connections. Such tabs can be used for provisional holding of the line body Edges or slits are hung in the housing parts of the washing machine.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels ist die Erfindung nachstehend erläutert.The invention is based on an exemplary embodiment shown in the drawing explained below.

In einem Waschmaschinengehäuse 1 sind beispielsweise an der Rückwand 2 ein Magnetventilblock
3 mit zwei Ausgängen und eine Waschmittel-Einspüleinrichtung 4 angebracht.
Die Waschmittel-Einspüleinrichtung 4 hat an ihrer rückwärtigen Unterseite
(nicht sichtbar) zwei Eingangsstutzen für die Zuführung von Frischwasser und einen
Überlaufstutzen für die Abführung von aus dem nicht dargestellten Laugenbehälter
über die Waschmittel-Zuführungsleitung (ebenfalls nicht dargestellt) und die Waschmittel-Einspüleinrichtung
4 überlaufendem Wasser. Ferner hat die Waschmittel-Einspüleinrichtung
4 noch einen Belüftungsstutzen, der mit der freien Atmosphäre Verbindung
hat. Dieser Belüftungsstutzen dient regelmäßig dazu, Luft aus der freien Atmosphäre
in einen Überlaufbogen des Laugenablaufsystems zu führen, damit bei Förderunterbrechung
der Laugenpumpe die Wassersäule im Steigrohr des Laugen-Abführungssystems
abreißt und nicht etwa per Saugheberprinzip den Inhalt des Laugenbehälters
absaugt.In a
Für all diese Leitungs-Aufgaben ist zwischen den wassertechnischen Behandlungs-Baugruppen
ein Leitungskörper 5 vorgesehen, an dessen Steigrohr 6 eine Wasserleitung
7 (einzelnes Bauteil) angeschlossen ist, die von einer nicht dargestellten Laugenpumpe
her abzupumpende Lauge führen kann. Die Integration der Leitung 7 in den
Leitungskörper 5 wäre technisch zwar möglich, ist aus Handhabungsgründen bei der
Montage jedoch nicht empfehlenswert, weil die Laugenpumpe sehr weit entfernt von
der Rückwand, nämlich möglichst weit an der Frontwand der Waschmaschine angeordnet
sein sollte. Daher wäre der Leitungskörper 5 viel zu ausladend und würde aus
diesem Grunde bei der logistischen Behandlung sowie bei der Montage Handhabungsschwierigkeiten
bereiten. An den Ausgangsstutzen des Fallrohres 8 des Leitungskörpers
5 ist eine Schlauchleitung 9 angeschlossen, die an einer hier nicht näher
dargestellten Stelle aus dem Maschinengehäuse 1 herausgeführt und daher auf einem
Teil ihrer Länge gestrichelt dargestellt ist. Der Rücklaufbehälter 10 liegt leitungstechnisch
im Zuge eines Überlaufbogens (Fig. 2) und ist recht flach gestaltet und vor einer
rückwärtigen Gehäusekante 11 um diese Kante geführt, um einerseits möglichst viel
Inhalt zu bieten, andererseits aber möglichst wenig vom durch das schwingende Laugenbehälteraggregat
benötigten Schwingraum zu belegen.For all these pipeline tasks is between the water treatment modules
a
Zur provisorischen Fixierung des Leitungskörpers 5 vor der Herstellung der Leitungsverbindungen
sind am Leitungskörper 5 Laschen 12 und 13 angebracht, die durch zugeordnete
Schlitze in der Gehäuserückwand gesteckt werden können und dem Leitungskörper
5 einen in Längsrichtung der Leitungen beweglichen Halt geben.For the provisional fixation of the
Der in Fig. 2 in Einzelheiten dargestellte Leitungskörper 5 enthält die bereits erörterten
Steig- und Fallrohre 6 und 8 und den im Zuge des Überlaufbogens 14 angeordneten
Rücklaufbehälter 10. Die abzupumpende Lauge aus dem Verbindungsrohr 7 füllt über
den Stutzen 15 und das Steigrohr 6 den Rücklaufbehälter 10, bevor sie über den
Überlaufbogen 14 und das Fallrohr 8 zum Ablaufschlauch 9 gelangt. Sobald der Pumpendruck
in der Steigleitung 6 nachläßt, fließt aus dem Stutzen 16 atmosphärische
Luft in den Überlaufbogen 14 und läßt die Laugensäulen aufreißen. Damit wird vermieden,
daß nach Erreichen des Überlaufbogens 14 der Laugenbehälter auch bei ausgeschalteter
Pumpe selbsttätig leergesaugt werden kann.The
Der Leitungskörper 5 enthält weiterhin Frischwasserzuführungsleitungen 17 und 18,
deren eingangsseitige Stutzen 19 und 20 über elastische Dichtungshülsen 21 und 22
mit nicht näher dargestellten Ausgangsstutzen der Magnetventile 3, (Fig. 1) verbunden
sind. In gleicher Weise sind die Ausgangsstutzen 23 und 24 der Leitungen 17 und 18
über Dichtungshülsen 25 und 26 mit den nicht dargestellten Eingangsstutzen der
Waschmittel-Einspüleinrichtung 4 verbunden. Zwischen den Zuführungsleitungen 17
und 18 ist im Leitungskörper 5 eine Leitung 27 zur Führung von Überlaufwasser angeordnet.
An ihren Eingangsstutzen 28 ist über eine Dichtungshülse 29 der ebenfalls
nicht sichtbare Überlaufstutzen in der Waschmittel-Einspüleinrichtung 4 angeschlossen.
Der ausgangsseitige Stutzen 30 der Leitung 27 kann entweder frei oder über eine
Dichtungshülse 31 in eine Wasserführungseinrichtung münden, die das abgeführte
Überlaufwasser in eine Bodenwanne 32 (Fig. 1) führt, wo nicht dargestellte Sicherheitsschalteinrichtungen
das Vorhandensein von Überlaufwasser ggf. signalisieren.The
Wie bereits zu Fig. 1 beschrieben, werden zur provisorischen Anbringung des Leitungskörpers
5 an der Rückwand der Waschmaschine die Laschen 12 und 13 in entsprechende
Schlitze eingeführt. Danach werden die Verbindungen der Leitungsstutzen
16, 19, 20, 23, 24, 28 und 30 über ihre zugeordneten Dichtungshülsen mit den fest in
der Waschmaschine angeordneten Baugruppen 3 und 4 verbunden. Zur Abstandhaltung
des Leitungskörpers an der Rückwand dienen Laschen 33 und 34, die in Richtung
auf die Rückwand hin abgeknickt sind und über die äußere Kontur des Leitungskörpers
hinausragen.As already described for FIG. 1, are used for the provisional attachment of the
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Insbesondere
sind die Leitungsführungen an die jeweiligen Gegebenheiten in einer Waschmaschine
anzupassen, was auch die Position und die Stellung der Anschlußstutzen betrifft.
Weiterhin können in dem Leitungskörper weitere Leitungen vorgesehen sein, beispielsweise
eine Frisch-Leckwasser-Leitung gemäß DE 37 34 117 A1. Sollte die Zuführung
von Frischwasser und Waschmittel aus der Waschmittel-Einspüleinrichtung 4
nicht im oberen Teil des Laugenbehälters angeschlossen sein, sondern über eine längere
Leitung in irgendeinen unten im Laugenbehälter liegenden Bereich einmünden,
dann empfiehlt sich ebenfalls die Integration der Wasser-Waschmittel-Leitung in den
Leitungskörper 5.The invention is not restricted to the exemplary embodiment shown. In particular
are the cable routing to the particular circumstances in a washing machine
adapt, which also affects the position and position of the connecting piece.
Furthermore, further lines can be provided in the line body, for example
a fresh leakage water line according to DE 37 34 117 A1. Should the feeder
of fresh water and detergent from the detergent dispenser 4
not be connected in the upper part of the tub, but over a longer one
Open the line into any area below in the tub,
then it is also recommended to integrate the water / detergent line into the
