Description

Die Erfindung geht aus von einer Waschmittel-Einspüleinrichtung mit über Waschmittel-Kammern in Betriebsposition angeordneten Frischwasser-Verteilungskanälen, die zum Zwecke der Zuführung des Frischwassers zu den Kammern am Boden mit Abflußlöchern versehen sind.The invention is based on a detergent dispenser arranged in the operating position via detergent compartments Fresh water distribution channels used for the purpose of Supply of fresh water to the chambers on the floor with drainage holes are provided.

Eine derartige Waschmittel-Einspüleinrichtung ist aus der DE 28 13 366 A1 bekannt. Darin haben die Abflußlöcher einen kreisförmigen Abflußquerschnitt geringer Größe, weil die Fachwelt bisher davon ausging, daß die Ausspülung von pulverförmigem Waschmittel aus der darunterliegenden Waschmittel-Kammer mittels scharfer Strahlen am besten zu bewerkstelligen sei. Dabei wurde angenommen, daß Waschpulver-Portionen am besten von der Seite her zu unterspülen und als kompakte Portion dem Laugenbehälter der Waschmaschine zuzuführen sind. Such a detergent dispenser is from the DE 28 13 366 A1 known. The drain holes have one in it circular drain cross-section of small size because the Experts previously assumed that the rinsing of powder Detergent from the detergent compartment below best done with sharp rays be. It was assumed that washing powder portions best to wash from the side and as to supply a compact portion to the washing machine tub are.

In der bekannten Waschmittel-Einspüleinrichtung sind außerdem Wasserzuführungs-Kanäle vorgesehen, die für eine möglichst bis zum Ende der Kanäle voll zu erhaltende Druckverteilung sorgen sollen, damit auch das in Strömungsrichtung letzte Abflußloch mit möglichst großem Druck beaufschlagt wird.In the known detergent dispenser are also Water supply channels provided for as possible pressure distribution to be fully maintained up to the end of the channels should ensure that this also in the direction of flow last drain hole with the greatest possible pressure becomes.

Es hat sich aber gezeigt, daß gerade hierbei nicht alle Wand- und Bodenbereiche der Waschmittel-Kammer von den Strahlen voll erfaßt werden und rückständige Waschpulver-Reste haften bleiben. Unter Verbindung mit der zugeführten Feuchtigkeit verkrusten solche Reste auf Dauer und behindern spätere Waschmittel-Einspülvorgänge.However, it has been shown that not all of them do just that Wall and floor areas of the detergent dispenser Rays are fully captured and residual washing powder residues stick. In connection with the supplied Moisture will crust over such residues in the long term and hinder them later detergent dispensing processes.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Waschmittel-Einspüleinrichtung der eingangs genannten Art die Ausspülung der Waschmittel-Kammer noch weiter zu verbessern.The invention has for its object in a detergent dispenser of the type mentioned at the beginning Rinsing the detergent chamber to improve even further.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß mindestens ein Teil der Abflußlöcher einen gegenüber den in Hauptströmungsrichtung des zufließenden Frischwassers seitlich angeordneten Löchern vergrößerten Abflußquerschnitt aufweist und daß in Hauptströmungsrichtung vor den vergrößerten Abflußlöchern ein Strömungsteiler angeordnet ist, der die Strömung hauptsächlich zu den seitlich angeordneten Löchern lenkt. Dadurch werden zunächst die seitlich angeordneten Löcher mit Zulaufwasser beaufschlagt, das mit verhältnismäßig geringem Druck durch die Löcher hindurch auf die Wandungen der darunterliegenden Kammer auftrifft und die Waschmittel-Portion unterspült. Zusätzlich gelangt aber überschüssiges Zuflußwasser über die seitlich angeordneten Löcher hinweg zum Ende des Verteilungskanals und wird dort von hinten her durch den mittleren Bereich des Verteilungskanals zurückgelenkt, in dem die Abflußlöcher mit vergrößertem Abflußquerschnitt angeordnet sind. Hier trifft das umgelenkte Zuflußwasser auf Strömungsverwirbelungen, die von vorn her am Strömungsteiler entstehen. Dadurch wird eine erhebliche Menge des Zuflußwassers auch über die Abflußlöcher mit vergrößerten Abflußquerschnitt auf die Waschmittel-Portion geführt, die dadurch von allen Seiten her stark mit Zuflußwasser vermischt und als Wasser-Pulver-Gemisch über einen Schacht dem Laugenbehälter zugeführt wird.According to the invention this object is achieved in that at least some of the drainage holes are opposite the in Main flow direction of the incoming fresh water laterally arranged holes enlarged drain cross section has and that in the main flow direction before the enlarged Drainage holes a flow divider is arranged, the the flow mainly to the laterally arranged holes directs. As a result, the sides are initially arranged Holes with inflow water acted on, the proportionately low pressure through the holes on the Walls of the chamber below and the Washed-in detergent portion. In addition, however excess inflow water over the side Holes away to the end of the distribution channel and is there from behind through the middle area of the distribution channel directed back in which the drain holes with enlarged Drain cross section are arranged. This is where the redirected hits Inflow water on swirling currents caused by arise at the front of the flow divider. This will be a significant one Amount of inflow water also through the drain holes with enlarged drain cross-section on the detergent portion led, which is strong from all sides with inflow water mixed and over as a water-powder mixture a shaft is fed to the tub.

In einem besonders vorteilhaften Ausführungsbeispiel der Erfindung ist der Strömungsteiler pfeilförmig gestaltet und mit seiner Pfeilspitze gegen die Strömung gerichtet. Eine pfeilförmige Gestaltung des Strömungsteilers kann am wirksamsten für eine Ausrichtung des Zulaufwassers auf die seitlich angeordneten Löcher dienen und ist am ehesten geeignet, durch Gestaltung seiner Form und/oder Anordnung die Strömung zielgerichtet abzulenken.In a particularly advantageous embodiment of the invention the flow divider is arrow-shaped and with its arrowhead directed against the current. A Arrow-shaped design of the flow divider can be most effective for aligning the inlet water to the side arranged holes serve and is most suitable the flow by designing its shape and / or arrangement to distract purposefully.

In vorteilhafter Weiterbildung der Erfindung weist der Strömungsteiler ein federartiges Ende auf, dessen Rückseite zu den vergrößerten Abflußlöchern weist. Dieses federartige Ende des Strömungsteilers kann deutlich zu einer druckmindernden Verwirbelung des zulaufenden Wassser beitragen, das in den Mittelteil des Verteilungskanals gelenkt und sich der zurückströmenden Zuflußmenge entgegenstellen soll. Damit wird die Bewässerung der Pulverportion in der darunterliegenden Kammer von oben her und deren Durchmischung intensiver.In an advantageous development of the invention, the flow divider a feathery end on the back of it the enlarged drain holes. That feathery end the flow divider can clearly become a pressure reducing Turbulence of the incoming water contribute to the directed the middle part of the distribution channel and the back flow to counter flow. In order to will irrigate the powder portion in the one below Chamber from above and their mixing more intensely.

In Weiterbildung der Erfindung ist wenigstens die Pfeilspitze und/oder die Feder unsymmetrisch zur Hauptströmungsrichtung gestaltet und/oder angebracht. Dies sind Mittel, um die Strömung entsprechend den Wünschen der Verteilung im Verteilungskanal wirksam abzulenken.A further development of the invention is at least the arrowhead and / or the spring asymmetrical to the main flow direction designed and / or attached. These are the means to Flow according to the wishes of the distribution in the distribution channel distract effectively.

In weiterer vorteilhafter Ausbildung der Erfindung sind in Hauptströmungsrichtung vor dem Strömungsteiler quer zur Hauptströmungsrichtung orientierte, schlitzartige Abflußlöcher über einer in der Waschmittel-Kammer angebrachten Schüttbegrenzungswand angeordnet. Hier kann in einem Bereich hoher Durchflußgeschwindigkeit ein Teil des Zuflußwassers bereits abgezweigt werden, um ein besonderes Bauteil der darunterliegenden Kammer zu bespülen, nämlich die Schüttbegrenzungswand, die verhindert, daß eine trockene Waschmittel-Portion vorzeitig über den Kammerausgang und einen Schacht zum Laugenbehälter hin abfließt. Diese Schüttbegrenzungswand kann Waschpulverteile über den Ausspülvorgang hinaus aufhalten, wenn sie lediglich feucht, aber nicht wirkungsvoll bespült wird.In a further advantageous embodiment of the invention are in Main flow direction upstream of the flow divider Main flow direction oriented, slit-like drain holes above one in the detergent dispenser Bulk boundary wall arranged. Here in one area high flow rate part of the inflow water already branched off to a special component of the to flush the chamber underneath, namely the bulkhead wall, which prevents a dry detergent portion ahead of the chamber exit and one Shaft flows down to the tub. This bulkhead wall can wash powder parts beyond the rinsing process stop if they are just damp but not effective is rinsed.

a in the main flow direction of the fresh water supplied and schematically shown detergent dispenser and
Fig. 2
a view of the bottom of a fresh water distribution channel in the upper part of the detergent dispenser according to an embodiment.

Die Waschmittel-Einspüleinrichtung 1 besteht aus einem Gehäuse 2 mit einem Oberteil 3 und einer Höhle 4 zum Einführen einer Schublade 5 mit mindestens einer Waschmittel-Kammer 6 zum Bevorraten einer Portion von Waschpulver. Die Schüttbegrenzungswand 7 verhindert, daß eine auf dem schräg auf den Schacht 8 zu geneigten Boden 9 lagernde Waschmittel-Portion vorzeitig dem Schacht 8 zufließt.The detergent dispenser 1 consists of a housing 2 with an upper part 3 and a cavity 4 for insertion a drawer 5 with at least one detergent chamber 6 for storing a portion of washing powder. The bulkhead wall 7 prevents one on the slant on the Chute 8 portion of detergent stored on inclined floor 9 flows to shaft 8 prematurely.

Im Oberteil befindet sich mindestens ein rückseitig angeordneter Frischwasser-Zuführungsstutzen 10, der über die freie Luftstrecke oberhalb des Schachtes 8 auf eine Öffnung 11 eines Frischwasser-Verteilungskanals 12 zielt. Im Boden 13 des Verteilungskanals 17 sind Abflußlöcher 14 angeordnet, die in die darunterliegende Kammer 6 gerichtet sind. Im dargestellten Ausführungsbeispiel liegen diese Abflußlöcher 14 in einem seitwärts angeschrägten Bodenteil. Sie haben teilweise einen kreisrunden und teilweise einen ovalen Abflußquerschnitt, der aber in jedem Fall größer ist als die am Ende des Verteilungskanals 12 angeordneten Abflußlöcher 15. Gemäß Fig.2 sind am Boden 13 des Verteilungskanals 12 weitere Abflußlöcher 16 mit einem kreuzförmigen Abflußquerschnitt angeordnet, der größer ist als der Abflußquerschnitt der runden Abflußlöcher 14. Die kreuzförmigen Abflußlöcher 16 sind in einem Raumbereich des Verteilungskanals 12 angeordnet, der einerseits von zurückfließender Strömung von hinten her und andererseits von vornher mit verwirbelter Strömung beaufschlagt ist. Diese beiden Strömungen treffen sich im Bereich der kreuzförmigen Abflußlöcher 16 und entspannen sich nahe drucklos über die Abflußlöcher in die darunterliegende Kammer.In the upper part there is at least one on the back Fresh water supply nozzle 10, which over the free Air gap above the shaft 8 to an opening 11 of a Fresh water distribution channel 12 targets. In the bottom 13 of the Distribution channel 17 are arranged drain holes 14 which in the underlying chamber 6 are directed. In the illustrated Embodiment, these drain holes 14 are in one sideways sloping bottom part. You have partial a circular and partly an oval drain cross-section, which in any case is larger than that at the end of the distribution channel 12 arranged drain holes 15. According Fig.2 are at the bottom 13 of the distribution channel 12 further drain holes 16 arranged with a cross-shaped discharge cross-section, which is larger than the discharge cross-section of the round Drain holes 14. The cruciform drain holes 16 are arranged in a spatial area of the distribution channel 12, on the one hand, from the backward flowing flow and, on the other hand, subjected to swirling flow from the start is. These two currents meet in the area of cruciform drain holes 16 and relax almost depressurized through the drain holes into the one below Chamber.

Hinter der Zuführungs-Öffnung 11 des Verteilungskanals 12 ist am Boden des Verteilungskanals ein Strömungsteiler 17 angeordnet, dessen Pfeilspitze 18 gegen die Strömung gerichtet ist und auf die Öffnung 11 zeigt. Diese Pfeilspitze 18 teilt die zulaufende Hauptströmung in zwei Zweigströmungen, die über die seitwärts angeschrägten Bodenteile zu den Abflußlöchern 14 streben. Frischwasser-Anteile, die nicht durch die Abflußlöcher 14 die darunterliegende Kammer erreicht haben, fließen teilweise noch über die Abflußlöcher 15 geringeren Querschnitts in die Kammer ab oder treffen sich am Ende des Verteilungskanals 12 wieder, um von dort dem Bereich der kreuzförmigen Abflußlöcher 16 der Hauptströmungsrichtung entgegenzufließen.Behind the feed opening 11 of the distribution channel 12 is a flow divider 17 at the bottom of the distribution channel arranged, the arrowhead 18 directed against the flow and points to the opening 11. This arrowhead 18th divides the incoming main flow into two branch flows, the over the laterally beveled bottom parts to the drain holes 14 strive. Fresh water shares that are not reached through the drain holes 14 the underlying chamber partly still flow through the drain holes 15 smaller cross section in the chamber or hit itself at the end of distribution channel 12 to get from there the area of the cross-shaped drain holes 16 of the main flow direction to flow towards.

Teile der durch die Pfeilspitze 18 geteilten Teilströme fließen schließlich am federartigen Ende 19 des Strömungsteilers 17 entlang und reißen an seinen rückseitigen Abrißkanten 20 ab. Dabei verwirbeln Teile der Teilströme und gelangen von vorn ebenfalls in den Bereich der kreuzförmigen Abflußlöcher 16, wo sie auf die Gegenströmung der Teilstromreste von der Rückseite des Verteilungskanals treffen. Diese aufeinandertreffenden Strömungsreste sind nahezu drucklos und fallen über die kreuzförmigen Löcher 16 von oben auf die darunterlagernde Waschmittel-Portion. Diese wird behutsam durchtränkt und mit dem durch die seitlich angeordneten Abflußlöcher hindurchtretenden Flüssigkeitsstrom dem Ausgang der Kammer 6 und schließlich dem Schacht 8 zugeführt, der das Wasser-Waschmittel-Gemisch schließlich dem Laugenbehälter zuleitet.Parts of the partial streams divided by the arrowhead 18 finally flow at the spring-like end 19 of the flow divider 17 along and tear at its rear tear-off edges 20 from. Parts of the partial flows swirl and reach from the front also in the area of the cruciform Drain holes 16 where they countercurrent the partial flow remnants from the back of the distribution channel. This clashing currents are almost depressurized and fall over the cruciform holes 16 from above serving of detergent underneath. This will be gentle soaked and with the through the side drain holes liquid flow passing through the outlet the chamber 6 and finally the shaft 8, which finally the water / detergent mixture in the tub feeds.

Zur zusätzlichen Unterstützung der Strömungsbildung am Ende des Verteilungskanals 12 dienen noch wandförmige und turmförmige Einbauten 21 und 22 entlang der seitlich angeordneten Abflußlöcher 14.To additionally support the flow formation at the end the distribution channel 12 are still wall-shaped and tower-shaped Baffles 21 and 22 along the side Drain holes 14.

Zwischen der Zuführungs-Öffnung 11 und der Pfeilspitze sind außerdem quer zur Hauptströmungsrichtung liegende, schlitzförmige Abflußlöcher 23 räumlich so angeordnet, daß bei eingeschobener Waschmitteleinspülschale 5 die Schüttbegrenzungswand 7 der unter dem Verteilungskanal 12 angeordneten Kammer 6 unterhalb der schlitzförmigen Abflußlöcher 23 positioniert ist. Dadurch werden Waschmittelreste, die die Schüttbegrenzungswand 7 aufgehalten hat und von der Feuchtigkeit des zugeführten Frischwassers festgehalten werden, in besonderer Weise von oben durch die schlitzartigen Abflußlöcher abgewaschen. Wegen der hohen Strömung des Zulaufwassers an dieser Stelle haben sich schlitzförmige Querschnitte der Ablauflöcher 23 größeren Querschnitts als vorteilhaft erwiesen.Are between the feed opening 11 and the arrowhead also slit-shaped, lying transversely to the main flow direction Drain holes 23 spatially arranged so that when inserted Detergent dispenser 5 the bulkhead wall 7 of the arranged under the distribution channel 12 Chamber 6 positioned below the slot-shaped drain holes 23 is. This will detergent residues that the Bulk boundary wall 7 has stopped and from the moisture of the fresh water supplied are recorded, in a special way from above through the slit-like drain holes washed. Because of the high flow of the inlet water at this point there are slit-shaped cross sections the drain holes 23 larger cross-section than advantageous proven.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Je nach Ausgestaltung der Verteilungskanäle und nach Anordnung von Abflußlöchern mehr oder weniger großen Querschnitts kann der Strömungsteiler eine von dem dargestellten Ausführungsbeispiel abweichende Form haben. Beispielsweise kann der Strömungsteiler aus einem im Querschnitt einem Dreieck ähnlichen, turmartigen Einbau hinter der Frischwasser-Zufluß-Öffnung 11 bestehen. Dabei ist in jedem Fall vorteilhaft, wenn eine Teilungskante dieses Einbaues (Strömungsteilers) gegen die Hauptströmungsrichtung und auf die Öffnung gerichtet ist.The invention is not based on the illustrated embodiment limited. Depending on the design of the distribution channels and after arranging drainage holes more or less large cross section, the flow divider can be one of those illustrated embodiment have a different shape. For example, the flow divider can consist of a cross section a triangular, tower-like installation behind the fresh water inflow opening 11 exist. Here is in in any case advantageous if a dividing edge of this installation (Flow divider) against the main flow direction and is directed towards the opening.
