Description

Die Erfindung geht aus von einer Waschmitteleinspüleinrichtung für eine Wäschebe­handlungsmaschine, die ein einseitig offenes Gehäuse und eine durch diese Öffnung bewegbare Schublade mit mehreren oben offenen Kammern für Waschmittel und Waschhilfsmittel enthält, wobei im Deckel des Gehäuses über jeder Kammer der eingeschobenen Schublade ein an eine Frischwasserdüse anschließender, mit bodensei­tigen Abflußlöchern versehener Wasserführungskanal angeordnet ist, dessen erster, im wesentlichen mit der Frischwasserdüse fluchtender Abschnitt sich an seinem Ende in zwei weitere Abschnitte mit gegen die Hauptfließrichtung des Zulaufwassers gerich­teter Fließrichtung verzweigt.The invention relates to a detergent dispenser for a laundry treatment machine, which contains a housing that is open on one side and a drawer that can be moved through this opening and has a plurality of compartments for detergents and washing aids that are open at the top is arranged, provided with bottom-side drainage holes, the first section, which is essentially aligned with the fresh water nozzle, branches at its end into two further sections with a flow direction directed against the main flow direction of the feed water.

Eine derartige Waschmitteleinspüleinrichtung ist aus der DE-OS 28 13 366 bekannt. In den beiden weiteren Abschnitten jedes Wasserführungskanals in der bekannten Waschmitteleinspüleinrichtung entstehen nicht klar definierbare Einzelströmungen, die zudem noch in ihrem Berührungsbereich zur Hauptströmung dieses Abschnittes eine Wirbelzone bilden. Diese Einzelströmungen formieren sich zum großen Teil zu einer Gegenströmung in diesem weiteren Abschnitt, die einen Teil der Energie in der Hauptströmung aufzehrt, so daß die Strahlenergie der aus den seitlichen Abflußlö­chern austretenden, auf die Kammerwände gerichteten Wasserstrahlen teilweise nicht ausreicht, um das Waschmittel aus der zugeordneten Kammer zufriedenstellend aus­zuspülen.Such a detergent dispenser is known from DE-OS 28 13 366. In the two further sections of each water guide channel in the known detergent dispensing device, individual flows which are not clearly definable arise and which also form a vortex zone in their contact area with the main flow of this section. These individual flows largely form a counterflow in this further section, which consumes part of the energy in the main flow, so that the jet energy of the water jets emerging from the lateral drain holes and directed onto the chamber walls is sometimes insufficient to detergent from the Rinsing out the assigned chamber satisfactorily.

Der Erfindung liegt die Aufgabe zugrunde, bei einer eingangs beschriebenen Wasch­mitteleinspüleinrichtung eine gegenseitig störende Beeinflussung von Hauptströmung und Einzelströmungen so zu verbessern, daß die erforderliche Strahlenergie zum zu­friedenstellenden Ausspülen des Waschmittels erhalten bleibt.The invention has for its object to improve a mutually interfering influence of the main flow and individual flows in a detergent dispenser described above so that the necessary beam energy for satisfactory rinsing of the detergent is maintained.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß am Ende der weiteren Ka­nalabschnitte je ein dritter Kanalabschnitt anschließt, dessen Strömungsrichtung im wesentlichen der des ersten Kanalabschnittes entspricht. Hierdurch können die ge­fürchteten Einzelströmungen im dritten Kanalabschnitt zu einer Gesamtströmung zu­sammengefaßt werden, die mit der Hauptströmung des weiteren Abschnitts nicht mehr in Berührung kommt. Ein hieraus herrührender Energieverzehr dieser Haupt­strömung ist daher ausgeschlossen. Es ist von besonderem Vorteil, im dritten Ab­schnitt ebenfalls Abflußlöcher vorzusehen, damit die Strömung in der Reihenschal­tung aller Kanalabschnitte erhalten bleibt und nicht etwa ein Stau verursacht wird, der wiederum zur Wirbelbildung führen würde.According to the invention, this object is achieved in that at the end of the further channel sections there is a third channel section, the flow direction of which essentially corresponds to that of the first channel section. As a result, the dreaded individual flows in the third channel section can be combined to form an overall flow which no longer comes into contact with the main flow of the further section. A resulting energy consumption of this main flow is therefore excluded. It is particularly advantageous to also provide drainage holes in the third section, so that the flow is maintained in the series connection of all the channel sections and does not cause a congestion, which in turn would lead to the formation of eddies.

Damit möglichst viel Strömungsenergie den ausspülenden Wasserstrahlen für die Kammerwände zur Verfügung steht, ist eine Weiterbildung der Erfindung besonders vorteilhaft, bei der der dritte Kanalabschnitt zwischen dem ersten und dem weiteren Kanalabschnitt gelegen ist.In order that as much flow energy as possible is available for the rinsing water jets for the chamber walls, a further development of the invention is particularly advantageous in which the third channel section is located between the first and the further channel section.

Zur Beruhigung der Strömungen in den Kanalabschnitten und zur Verminderung des Strömungsgeräusches trägt insb. eine weitere Ausbildung der Erfindung bei, in der sich zwischen dem ersten und dem dritten sowie zwischen dem dritten und dem weiteren Kanalabschnitt jeweils Trennwände befinden, die im Verzweigungsbereich am Ende des ersten Kanalabschnitts durch eine bogenförmige Wand miteinander ver­bunden sind, die etwa parallel zur Zweigströmung im Umlenkbereich geformt ist.A further embodiment of the invention, in particular, contributes to calming the flows in the channel sections and reducing the flow noise, in which there are partition walls between the first and the third and between the third and the further channel section, which are in the branching area at the end of the first Channel section are connected to each other by an arcuate wall which is shaped approximately parallel to the branch flow in the deflection area.

Anhand von in der Zeichnung dargestellten Ausführungsbeispielen ist die Erfindung zusammen mit weiteren vorteilhaften Merkmalen nachstehend erläutert.On the basis of exemplary embodiments shown in the drawing, the invention is explained below together with further advantageous features.

Das als Deckel für das Gehäuse einer Waschmitteleinspüleinrichtung ausgebildete Wasserführungsbauteil 1 trägt an seiner Rückwand Frischwasserdüsen 2, 3 und 4. Sie münden in eine Vorkammer 5, die zum Abführen des Tropfwassers in den Waschbe­hälter und zur Rückflußverhinderung bereits in die Waschmitteleinspülkammer gelangten Wassers dient. In einem flachen, kastenförmigen Teil des Wasserführungs­bauteiles sind gegenüber den Frischwasserdüsen 2 bis 4 Öffnungen 6, 7 und 8 ange­ordnet, von denen die Öffnungen 6 und 8 zu ersten Abschnitten 9 und 10 der zu den mit Waschpulver füllbaren Waschmittelkammern führenden Wasserführungskanäle ge­ hören. In diesen ersten Abschnitten 9 und 10 sind bereits zu den darunter liegenden Waschmittelkammern führende Abflußlöcher 11 und 12 vorgesehen. Falls es be­stimmte Bedingungen ermöglichen, kann auf diese Abflußlöcher 11 und 12 auch ver­zichtet werden.The water guiding component 1 designed as a cover for the housing of a detergent dispenser has fresh water nozzles 2, 3 and 4 on its rear wall. They open into a prechamber 5 which serves to discharge the dripping water into the wash container and to prevent backflow of water that has already entered the detergent dispenser chamber. In a flat, box-shaped part of the water guide component 2 to 4 openings 6, 7 and 8 are arranged opposite the fresh water nozzles, of which the openings 6 and 8 to first sections 9 and 10 of the water supply channels leading to the detergent chambers fillable with washing powder Listen. In these first sections 9 and 10 drainage holes 11 and 12 leading to the detergent chambers below are already provided. If certain conditions allow, these drain holes 11 and 12 can also be omitted.

Die der Frischwasserdüse 3 gegenüberliegende Öffnung 7 gehört zu einem Wasserfüh­rungskanal 13, der zur Zuführung des für die Entleerung der unter den Abflußlöchern 14 angeordneten Weichspülmittel-Kammer (nicht dargestellt) benötigten Zulaufwas­sers dient. Am Ende der durch die Trennwände 15 bis 18 begrenzten ersten Ab­schnitte 9 und 10 verzweigt sich der jeweilige Wasserführungskanal, wobei die weiteren Abschnitte als Kanalzweige 19 bis 22 parallel zum jeweils ersten Abschnitt 9 bzw. 10 liegen, vom Zulaufwasser jedoch in Gegenrichtung durchströmt werden.The opening 7 opposite the fresh water nozzle 3 belongs to a water guide channel 13 which serves to supply the inlet water (not shown) required for emptying the fabric softener chamber arranged under the drain holes 14. At the end of the first sections 9 and 10 delimited by the partition walls 15 to 18, the respective water guide channel branches, the further sections as channel branches 19 to 22 lying parallel to the first section 9 and 10, respectively, but through which the supply water flows in the opposite direction.

In den äußeren Randbereichen der Kanalzweige 19 bis 22 sind in einer Reihe hin­tereinander angeordnete Abflußlöcher 23 bzw. 24 vorgesehen. Das in den nicht dargestellten Waschmittelkammern lagernde Waschpulver wird von den die Abflußlö­cher 23 bzw. 24 durchfließenden Wasserstrahlen unterspült und vom Zulaufwasser durch die Vorkammer 5 in den Waschbehälter befördert.In the outer edge regions of the channel branches 19 to 22, drain holes 23 and 24 are provided in a row one behind the other. The washing powder which is stored in the detergent compartments (not shown) is rinsed by the water jets flowing through the drain holes 23 and 24 and is conveyed from the feed water through the antechamber 5 into the washing container.

Die im linken Teil der Fig. 3 in den Kanalabschnitten 10, 20 und 22 eingetragenen Symbole weisen entsprechend den Pfeilen in Fig. 1 und 2 auf die jeweilige Fließ­richtung des Zulaufwassers hin. In Fig. 3 sind ferner durch die Seitenwände 25 und die Trennwände 26 die unter den Kanalabschnitten angeordneten Waschmittelkam­mern angedeutet.The symbols entered in the left-hand part of FIG. 3 in the channel sections 10, 20 and 22 indicate, in accordance with the arrows in FIGS. 1 and 2, the respective direction of flow of the inlet water. In FIG. 3, the detergent chambers arranged under the channel sections are also indicated by the side walls 25 and the partition walls 26.

Die erfindungsgemäße Ausgestaltung der Wasserführungskanäle umfaßt am Ende der ersten Kanalabschnitte 9 und 10 im Verzweigungsbereich bogenförmige Wandab­schnitte 27, durch welche die Trennwände 15 bis 18 im Umlenkbereich verlängert sind. An die bogenförmigen Wandabschnitte 27 schließen sich weitere, parallel zu den ersten Trennwänden 15 bis 18 liegende Trennwände 28 an. Hierdurch werden jeweils dritte Kanalabschnitte 29 gebildet, die an das jeweilige Ende der weiteren Kanalabschnitte 19 bis 22 anschließen. Am Boden dieser dritten Kanalabschnitte 29 sind ebenfalls Abflußlöcher 30 angeordnet, durch die das in die dritten Kanalab­schnitte 29 gelangte Zulaufwasser in die darunter befindliche Waschmittelkammer abfließen kann. Im Verzweigungsbereich am Ende des jeweils ersten Kanalabschnittes 9 bzw. 10 ist noch ein Keil 31 angeordnet, der die Bildung von laminaren Strömun­gen im Umlenkbereich unterstützt.The configuration of the water guide channels according to the invention comprises, at the end of the first channel sections 9 and 10 in the branching area, arcuate wall sections 27, by means of which the partition walls 15 to 18 are extended in the deflection area. The arch-shaped wall sections 27 are followed by further partition walls 28 lying parallel to the first partition walls 15 to 18. In this way, third channel sections 29 are formed in each case, which connect to the respective end of the further channel sections 19 to 22. At the bottom of these third channel sections 29 there are also drain holes 30 through which the inlet water which has entered the third channel sections 29 can flow into the detergent chamber located below. In the branching area at the end of the first channel section 9 or 10 there is also a wedge 31 which supports the formation of laminar flows in the deflection area.

Die gezeigte Anordnung von in Reihe geschalteten und ineinander gefalteten Kanal­abschnitten führt zu einer Beruhigung und Vergleichmäßigung der Strömungen in den einzelnen Kanalabschnitten, in denen Wirbelbildungen und Stauungen weitgehend ver­mieden werden. Die Rundungen innerhalb der Strömungsbereiche führen außerdem zu einer erheblichen Geräuschminderung, weil in der Strömung enthaltene Luftbläschen ebenfalls beruhigt mitschwimmen, ohne durch unstete Richtungsänderungen zu Schwingungen angeregt zu werden.The arrangement of channel sections which are connected in series and which are folded into one another leads to a calming and equalization of the currents in the individual channel sections, in which vortex formation and congestion are largely avoided. The curvatures within the flow areas also lead to a considerable reduction in noise, because air bubbles contained in the flow also swim comfortably without being stimulated to vibrate due to irregular changes in direction.

Aus Fig. 3 sind anhand der Symbole noch die Strömungsrichtungen innerhalb der dritten Kanalabschnitte 29 zu entnehmen. Daraus ist erkennbar, daß die Strömung in jedem dieser Kanalabschnitte mit der Strömung in den ersten Kanalabschnitten 9 und 10 gleichgerichtet sind.The flow directions within the third channel sections 29 can also be seen from FIG. 3 using the symbols. It can be seen from this that the flow in each of these channel sections is rectified with the flow in the first channel sections 9 and 10.

In Fig. 4 ist anhand einer Einzelheit IV aus Fig. 2 eine andere Ausgestaltung des Umlenkbereiches ersichtlich. Hierin sind die bogenförmigen Trennwand-Abschnitte 27 kegelförmig gestaltet als kegelmantelförmige Abschnitte 32. Wie sich nämlich ge­zeigt hat, kann die Strömungsenergie durch eine derartige Maßnahme in die Bereiche der Abflußlöcher konzentriert werden. Zur geeigneten Entformbarkeit von entspre­chend gestalteten Kunststoffteilen des Wasserführungsbauteils ist im Beispiel der Fig. 4 die Trennlinie in den Bodenbereich der Wasserführungskanäle zu legen.4, another embodiment of the deflection area can be seen on the basis of a detail IV from FIG. 2. In this, the arcuate partition sections 27 are conical as conical sections 32. As has been shown, the flow energy can be concentrated in the areas of the drain holes by such a measure. In the example of FIG. 4, the dividing line is to be placed in the bottom region of the water guide channels in order to be able to demold appropriately designed plastic parts of the water guide component.
