Abstract
Description
Die Erfindung betrifft eine programmgesteuerte Waschmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a program-controlled Washing machine according to the preamble of claim 1.
In dem Patent . . . (Patentanmeldung P 195 00 370.5) ist eine Waschmaschine beschrieben, bei der das Waschgut in der Wäschetrommel über eine Besprühungseinrichtung unmittelbar mit Frischwasser beaufschlagt wird. Diese Besprühungseinrichtung wird über einen am Frischwasserleitungsnetz angeschlossenen Frischwasserzulauf entsprechend versorgt.In the patent. . . (Patent application P 195 00 370.5) is one Washing machine described in which the laundry in the Laundry drum directly via a spray device is supplied with fresh water. These Spraying device is on a Fresh water supply network connected fresh water supply appropriately supplied.
Die vorliegende Erfindung bezweckt eine Weiterbildung des Gegenstandes nach dem Patent . . . (Patentanmeldung P 195 00 370.5), um dessen Funktion und Betriebssicherheit zu verbessern.The present invention aims to develop the Item according to the patent. . . (Patent application P 195 00 370.5) in order to ensure its function and operational safety improve.
Die Lösung gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruchs 1 zu entnehmen.The solution according to the invention is the characteristic part of claim 1.
Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further refinements of the subject of Invention are specified in the subclaims.
Durch die vorgeschlagenen Maßnahmen wird verhindert, daß verunreinigtes Wasser bzw. Lauge aus der Waschmaschine bzw. deren Waschbottich in das Frischwasserleitungsnetz gelangen kann.The proposed measures prevent contaminated water or lye from the washing machine or whose wash tub get into the fresh water supply network can.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung rein schematisch dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is in the drawing shown purely schematically and is based on this described in more detail below.
Die in der Zeichnung dargestellte Waschmittel-Einspülwanne 5 für eine Waschmaschine hat einen bodenseitigen Ablauf 20. Über einen Faltenbalg 21 ist dieser Ablauf mit einem Waschbottich (Laugenbehälter) verbindbar. Der Waschmittel- Einspülwanne 5 ist ein am Wasserleitungsnetz angeschlossener Frischwasserzulauf 7 zugeordnet, der mit seiner Auslaufdüse 8 in einem Aufnahmetrichter 9 mündet. Dieser Aufnahmetrichter geht in eine Flüssigkeitsleitung 11 über, deren Austritt 11′ in einer Düsenanordnung in einer Faltenbalgdichtungsmanschette des Laugenbehälters endet, wie im Patent . . . . (Patentanmeldung P 195 00 370.5) dargestellt und beschrieben ist.The detergent dispenser 5 for a washing machine shown in the drawing has a bottom drain 20 . This drain can be connected to a washing tub (tub) via a bellows 21 . The detergent dispenser trough 5 is assigned a fresh water inlet 7 connected to the water supply network, which ends with its outlet nozzle 8 in a receiving funnel 9 . This receiving funnel merges into a liquid line 11 , the outlet 11 'ends in a nozzle arrangement in a bellows sealing sleeve of the tub, as in the patent. . . . (Patent application P 195 00 370.5) is shown and described.
Um nun zu verhindern, daß verunreinigtes Wasser/Lauge aus dem Laugenbehälter der Waschmaschine über den Frischwasserzulauf 7 in das Wasserleitungsnetz zurückgesaugt wird, ist im Frischwasserzulauf 7 neben einer Zulaufdüse 22 ein sogenannter Rückflußverhinderer 23 vorgesehen. Dieser Rückflußverhinderer besteht aus einer freien Fließstrecke 24, die durch eine im unteren oder über dem gesamten Rohrwandungsbereich des Frischwasserzulaufs 7 vorgesehene Rohrunterbrechung 25 vor dem Austritt der Düse 22 ausgebildet ist. Diese Rohrunterbrechung 25 ist zweckmäßig mit einem Auffangkörper 26 dicht verkleidet, der über einen Wasserablauf 27 mit der Einspülwanne 5 in Verbindung steht, so daß Auffangwasser (Leckwasser) in die Einspülwanne 5 und von dort in den Laugenbehälter zurückfließen kann. Als weitere Sicherheitsmaßnahme ist der Aufnahmetrichter 9, in den die Auslaufdüse 8 des Frischwasserzulaufs 7 endet, über eine seitliche Überlauf- bzw. Austrittsöffnung 28 ebenfalls mit der Einspülwanne 5 in Verbindung gebracht, so daß bei Überfüllung des Laugenbehälters in die Flüssigkeitsleitung 11 zurückgedrängte Lauge in die Einspülwanne 5 und von dort wieder in den Laugenbehälter der Waschmaschine zurückgelangen kann. Dadurch wird verhindert, daß in einem solchen Überlauffall kein verunreinigtes Wasser in den Frischwasserzulauf 7 gedrückt wird.In order to prevent contaminated water / liquor is sucked from the tub of the washing machine through the fresh water inlet 7 in the water mains, in the fresh water inlet 7 a so-called return valve 23 in addition to a inlet nozzle 22 is provided. This backflow preventer consists of a free flow section 24 which is formed by a pipe interruption 25 provided in the lower or over the entire pipe wall area of the fresh water inlet 7 before the nozzle 22 emerges. This pipe interruption 25 is expediently clad tightly with a collecting body 26 which is connected to the induction pan 5 via a water outlet 27 , so that collecting water (leak water) can flow back into the induction pan 5 and from there into the tub. As a further safety measure, the receiving funnel 9 , into which the outlet nozzle 8 of the fresh water inlet 7 ends, is also connected to the induction trough 5 via a lateral overflow or outlet opening 28 , so that when the suds container is overfilled, the alkali pushed back into the liquid line 11 into the Einspülwanne 5 and from there back into the washing machine tub. This prevents that in such an overflow situation, no contaminated water is pressed into the fresh water inlet 7 .
