Abstract

Fresh water stored in a reservoir is provided for flushing out the active-substance collecting channel. This reservoir is self-contained and is arranged above the working vessel (for example, the tub of a washing machine). The controllable fresh-water connecting line opens at the highest point into the fresh-water reservoir, at the bottom of which is connected the suction line leading to the collecting channel. Moreover, guided on the reservoir is an overflow line, the downwardly open mouth of which is arranged so far below the mouth of the fresh-water connecting line that the space in the reservoir above the mouth of the overflow orifice is so large that the volume of the overflow line can fill it only to a maximum of 20 mm below the mouth of the fresh-water connecting line. <IMAGE>

Description

Die Erfindung geht aus von einem Frischwasser-Vorratsbehälter für eine Vorrichtung zum einzelnen, dosierten Fördern von mehreren pumpbaren Wirkstoffen aus je einem Vorratsbehälter in einen gemeinsamen Arbeitsbehälter und zum Mischen der geförderten Wirkstoffe in einem Sammelkanal mit einem Arbeitsmedium, das über eine steuerbare Frischwasser-Anschlußleitung in den Frischwasser-Vorratsbehälter geführt wurde und aus einer an diesen Behälter angeschlossenen Ansaugleitung entnommen wird, wobei insbesondere die Wirkstoffe Waschmittel-Wirkstoffe, das Arbeitsmedium Wasser und der Arbeitsbehälter der Laugenbehälter einer Waschmaschine sind.The invention relates to a fresh water storage container for a device for the individual, metered delivery of several pumpable active substances from each storage container into a common working container and for mixing the conveyed active substances in a collecting channel with a working medium which is connected to a controllable fresh water connection line the fresh water storage container has been guided and is removed from a suction line connected to this container, the active substances in particular being detergent substances, the working medium water and the working container being the detergent solution container of a washing machine.

Ein derartiger Vorratsbehälter ist aus der DE-PS 32 37 785 bekannt. Er ist durch einen Nebenweg der Frischwasser-Anschlußleitung füllbar und hat ein Be- und Entlüftungsventil, das den Durchtritt von Wasser sperrt, so daß der Vorratsbehälter vollständig gefüllt werden kann, ohne überzulaufen. Sein Volumen ist so bemessen, daß die darin gespeicherte Frischwassermenge ausreicht, die Wirkstoffe aller für einen Waschprozeß benötigten Einzeldosen vollständig in den Arbeitsbehälter zu spülen. Allerdings ist das wassersperrende Be- und Entlüftungsventil einigermaßen kostspielig und auch störanfällig. DVGW-Forderungen nach Rücksaugsicherheit sind überhaupt nicht beachtet worden.Such a storage container is known from DE-PS 32 37 785. It can be filled by a bypass of the fresh water connection line and has a ventilation valve that blocks the passage of water so that the reservoir can be filled completely without overflowing. Its volume is such that the amount of fresh water stored therein is sufficient to completely flush the active ingredients of all the individual doses required for a washing process into the working container. However, the water-blocking ventilation valve is somewhat expensive and also prone to failure. DVGW requirements for back suction safety have not been observed at all.

Der Erfindung liegt die Aufgabe zugrunde, einen Frischwasser-Vorratsbehälter der eingangs genannten Art anzugeben, der billig und funktionssicher ist und außerdem die hohen Anforderungen des DVGW hinsichtlich der Rücksaugsicherheit erfüllt.The invention has for its object to provide a fresh water reservoir of the type mentioned, which is cheap and reliable and also meets the high requirements of the DVGW with regard to safety against suction.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der an sich geschlossene Frischwasser-Vorratsbehälter oberhalb des Arbeitsbehälters angeordnet ist, daß die steuerbare Frischwasser-Anschlußleitung an der höchsten Stelle in den Frischwasser-Vorratsbehälter mündet, daß die Ansaugleitung am Boden des Frischwasser-Vorratsbehälters angeschlossen ist und daß eine nach unten offene Mündung einer über eine freie Luftstrecke in den Arbeitsbehälter geführten Überlaufleitung so weit unterhalb der Mündung der Frischwasser-Anschlußleitung angeordnet ist, daß der Raum im Frischwasser-Vorratsbehälter oberhalb der Mündung der Überlaufleitung so groß ist, daß ihn das Volumen der Überlaufleitung nur bis maximal 20 mm unterhalb der Mündung der Frischwasser-Anschlußleitung auffüllen kann.According to the invention, this object is achieved in that the closed fresh water storage container is arranged above the working container, that the controllable fresh water connection line opens at the highest point in the fresh water storage container, that the suction line is connected to the bottom of the fresh water storage container and that a downwardly open mouth of an overflow line led through a free air gap into the working container is arranged so far below the mouth of the fresh water connection line that the space in the fresh water storage container above the mouth of the overflow line is so large that the volume of the overflow line can only fill up to a maximum of 20 mm below the mouth of the fresh water connection pipe.

Hierdurch läßt sich ein solcher Vorratsbehälter durch eine steuerbare Frischwasser-Anschlußleitung derartig füllen, daß diese Anschlußleitung für eine vorgegebene Zeit durchlässig gesteuert wird, die mit Sicherheit ausreicht, bei gegebener Durchströmgeschwindigkeit den Vorratsbehälter zu füllen. Zuviel in den Behälter eingefülltes Frischwasser wird über die Überlaufleitung in den ohnehin mit Wasser aufzufüllenden Arbeitsbehälter gedrückt. Ein solchermaßen gefüllter Vorratsbehälter kann trotzdem nicht seinen Inhalt wieder durch die Frischwasser-Anschlußleitung abgeben, wenn bei geöffnetem Ventil der Anschlußleitung im Frischwasser-Speisenetz ein Unterdruck entstünde. Dann würde nämlich das sich in der Überlaufleitung befindliche Wasservolumen in den Vorratsbehälter ziehen, die Überlaufleitung sodann Luft ansaugen und der Wasserspiegel im Vorratsbehälter nur bis zu einer Höhe 20 mm unterhalb der Mündung der Frischwasser-Anschlußleitung ansteigen. Bei weiterem Saugen durch die Anschlußleitung würde dann nur noch über die Überlaufleitung angesaugte Luft aufgenommen werden.In this way, such a storage container can be filled by a controllable fresh water connection line in such a way that this connection line is controlled permeably for a predetermined time, which is certainly sufficient to fill the storage container at a given flow rate. Too much fresh water poured into the tank is pressed into the work tank, which is to be filled with water anyway, via the overflow line. A reservoir filled in this way can still not release its contents through the fresh water connection line if a vacuum would be created in the fresh water supply network when the valve of the connection line is open. Then the water volume in the overflow line would pull into the storage tank, the overflow line would then suck in air and the water level in the storage tank would only rise up to a height of 20 mm below the mouth of the fresh water connection line. With further suction through the connecting line, only air sucked in via the overflow line would then be taken up.

Bei einer Haushalt-Waschmaschine kann der erfindungsgemäße Vorratsbehälter dadurch vorteilhaft weitergebildet werden, daß die Überlaufleitung über eine Waschmittel-Einspülschale geführt ist. In diesem Falle kann nämlich der Vorratsbehälter so dicht bei der Waschmittel-Einspülschale angeordnet werden, daß das Volumen der Überlaufleitung ihrer Kürze wegen sehr gering ist. Dies hat eine vorteilhafte Auswirkung auf die Gestaltung des Vorratsbehälters dadurch, daß der "tote" Raum zwischen den Mündungen der Frischwasser-Anschlußleitung und der Überlaufleitung sehr klein gehalten werden kann.In the case of a household washing machine, the storage container according to the invention can advantageously be further developed in that the overflow line is guided over a detergent dispenser. In this case, the reservoir can be so close to the detergent dispenser that the volume the overflow line is very small because of its brevity. This has an advantageous effect on the design of the storage container in that the "dead" space between the mouths of the fresh water connection line and the overflow line can be kept very small.

Anhand des in der Zeichnung dargestellten Ausführungsbeispiels ist die Erfindung nachstehend erläutert. Es zeigen:

The invention is explained below using the exemplary embodiment shown in the drawing. Show it:
Fig. 1
a diagram for the device provided for the storage and metered conveying of active ingredients with a fresh water reservoir according to the invention and
Fig. 2
is a schematic view of a storage container arranged next to a detergent dispenser.

Die Wirkstoffbehälter 1 bis 5 sind über Leitungen 6 bis 10 an die einzeln ansteuerbaren Ventile 13 bis 17 angeschlossen. Zusätzlich zu den Vorratsbehältern 1 bis 5 ist ein weiterer Vorratsbehälter 40 für Wasser vorgesehen, der über die Arbeitsmedium-Ansaugleitung 11 mit dem Ventil 12 verbunden ist. In diesen Vorratsbehälter 40 mündet die Frischwasser-Zulaufleitung 402, die über das Magnetventil 403 mit der Frischwasser-Anschlußleitung 406 verbunden ist.The active substance containers 1 to 5 are connected via lines 6 to 10 to the individually controllable valves 13 to 17. In addition to the storage containers 1 to 5, a further storage container 40 for water is provided, which is connected to the valve 12 via the working medium suction line 11. The fresh water supply line 402, which is connected to the fresh water connection line 406 via the solenoid valve 403, opens into this storage container 40.

Die Ventile 12 bis 17 münden jeweils in den Sammelkanal 19, dessen Ausgang 20 über eine Pumpe 21 und eine Leitung 22 im Arbeitsbehälter 35 mündet. Der Ventilblock, in dem alle Ventile angeordnet sind, enthält auch eine hier nicht näher dargestellte Steuereinrichtung für die Ventile. Der Sammelkanal 19 ist so gestaltet, daß eine gute Durchspülung gewährleistet ist und daß während der Stillstandzeiten der Pumpe 21 aus den Ventilen 13 bis 17 evtl. nachlaufende geringe Wirkstoffmengen sich nicht miteinander vermischen können. Dies kann bei einem gestreckt dargestellten Sammelkanal 19 durch eine eingefügte Schnecke erreicht werden, die den Sammelkanal 19 quasi in einzelne Kammern unterteilt, die jedoch in Reihenschaltung untereinander so verbunden sind, daß bei offenem Ventil 12 und laufender Pumpe 21 das Frischwasser in Richtung auf den Ausgang 20 mit hoher Durchflußgeschwindigkeit durch den Sammelkanal 19 fließt.The valves 12 to 17 each open into the collecting channel 19, the outlet 20 of which opens into the working container 35 via a pump 21 and a line 22. The valve block, in which all the valves are arranged, also contains a control device for the valves, which is not shown here. The collecting channel 19 is designed in such a way that a good flushing is ensured and that possibly small amounts of active substance that are running in from the valves 13 to 17 cannot mix with one another during the down times of the pump 21. This can be achieved in a stretched collection channel 19 by an inserted screw, which divides the collection channel 19 into individual chambers, but which are connected in series so that the fresh water in the direction of the exit with the valve 12 open and the pump 21 running 20 flows through the collecting channel 19 at a high flow rate.

Zum Auffüllen und zum Entleeren des Frischwasser-Vorratsbehälters ist eine Ent- und Belüftung erforderlich. Hierzu ist die Überlaufleitung 401 vorgesehen, deren nach unten offene Mündung soweit in den Vorratsbehälter 40 ragt, daß der Raum im Vorratsbehälter 40 oberhalb dieser Mündung um so viel größer ist, daß ihn das Volumen der Überlaufleitung nur bis maximal 20 mm unterhalb der Mündung der Frischwasser-Anschlußleitung 402 auffüllen kann. In anderen Worten ist das Maß 407 so groß, daß der oberhalb der Mündung der Überlaufleitung 401 liegende Raum des Vorratsbehälters so groß ist, daß er einerseits den gesamten Inhalt der Überlaufleitung 401 in sich aufnehmen kann und dann das im Vorratsbehälter 40 sich einstellende Niveau der aufgenommenen Flüssigkeit noch 20 mm unterhalb der Mündung der Frischwasser-Anschlußleitung 402 steht. Die Überlaufleitung 401 mündet entweder direkt - wie in Fig. 1 dargestellt - in den Arbeitsbehälter 35, wobei dieser Anschluß über eine freie Luftstrecke 405 hergestellt ist, damit beim Rücksaugen von Wasser aus der Überlaufleitung in den Vorratsbehälter 40 aus dem Arbeitsbehälter 35 keine Lauge angesaugt werden kann.Venting and ventilation is required to fill and empty the fresh water reservoir. For this purpose, the overflow line 401 is provided, the downwardly open mouth of which extends so far into the reservoir 40 that the space in the reservoir 40 above this mouth is so much larger that the volume of the overflow line is only up to a maximum of 20 mm below the mouth of the fresh water Connection line 402 can fill up. In other words, the dimension 407 is so large that the space of the storage container above the mouth of the overflow line 401 is so large that on the one hand it can absorb the entire contents of the overflow line 401 and then the level of the received in the storage container 40 Liquid is still 20 mm below the mouth of the fresh water connection line 402. The overflow line 401 either opens directly - as shown in FIG. 1 - into the working container 35, this connection being made via a free air gap 405 so that no lye is sucked out of the working container 35 when water is sucked back from the overflow line into the reservoir 40 can.

Eine besonders vorteilhafte Ausführungsform eines Vorratsbehälters für Waschmaschinen, die außer der in Fig. 1 dargestellten Einrichtung mit einer Waschmittel-Einspülschale zum Bevorraten von handdosierten Waschmittelmengen ausgestattet ist, ist in Fig. 2 dargestellt. Die Waschmittel-Einspüleinrichtung 5 hat am Boden eine Öffnung 50, die über eine nicht dargestellte Schlauchleitung mit dem Arbeitsbehälter 35 der Waschmaschine verbunden ist. Die im einzelnen nicht näher dargestellte Waschmittel-Einspüleinrichtung 5 hat noch Wasserzuleitungen, die über weitere Magnetventile 51 und 52 gesteuert werden, deren Eingänge ebenfalls an die Frischwasser-Anschlußleitung 406 angeschlossen sind. An einem hohen Punkt der Waschmittel-Einspüleinrichtung ist die Überlaufleitung 401 des Frischwasser-Vorratsbehälters 40 angekoppelt. Da dieser Vorratsbehälter 40 in nächster Nähe zur Waschmittel-Einspüleinrichtung 5 angeordnet sein kann, ist auch seine Überlaufleitung 401 sehr kurz. Ihr Inhalt ist dementsprechend gering, so daß die Raumhöhe 407 zwischen der nach unten gerichteten Mündung der Überlaufleitung 401 und der Mündung der Frischwasser-Anschlußleitung 402 entsprechend klein sein kann. Die zu Fig. 1 bereits genannten Bedingungen für die Eintauchtiefe der Überlaufleitung in den Vorratsbehälter 40 bleiben jedoch auch hier erhalten.A particularly advantageous embodiment of a storage container for washing machines, which, in addition to the device shown in FIG. 1, is equipped with a detergent dispenser tray for storing hand-dosed amounts of detergent, is shown in FIG. 2. The detergent dispenser 5 has an opening 50 on the bottom, which is connected to the working container 35 of the washing machine via a hose line (not shown). The detergent dispenser 5, not shown in detail, also has water supply lines which are controlled by further solenoid valves 51 and 52, the inputs of which are also connected to the fresh water connection line 406. The overflow line 401 of the fresh water storage container 40 is coupled to a high point of the detergent dispenser. Since this storage container 40 can be arranged in close proximity to the detergent dispenser 5, its overflow line 401 is also very short. Their content is accordingly low, so that the room height 407 between the downward mouth of the overflow line 401 and the mouth of the fresh water connection line 402 can be correspondingly small. The conditions already mentioned for FIG. 1 for the immersion depth of the overflow line in the reservoir 40 are, however, also retained here.
