Description

Die Erfindung richtet sich auf eine Vorrichtung zur portionierten Bevorratung und allmählichen Abgabe von Flüssigprodukt, insbe­sondere Flüssigwaschmittel, in das Waschwasser einer Waschma­schine sowie ein Verfahren zu dessen Anwendung.The invention relates to a device for portioned storage and gradual dispensing of liquid product, in particular liquid detergent, into the washing water of a washing machine and a method for its use.

Da die Einspülrinnen handelsüblicher Waschmaschinen heutzutage für die Aufnahme von Waschpulver ausgelegt sind, ergeben sich für die Anwendung von Flüssigprodukten, insbesondere Flüssig­waschmitteln, in Waschmaschinen erhebliche Schwierigkeiten. Im Gegensatz zu Waschpulver, das in den Einspülrinnen von Wasch­maschinen allmählich mit dem einlaufenden Wasser in die Wasch­trommel gespült wird und sich auch dort noch gleichmäßig verteilt auflöst, fließt flüssiges Waschmittel entweder sogleich in die Waschmachine oder wird sofort mit dem einlaufenden Wasser in die Waschmaschine gespült. Dies beeinträchtigt in erheblichem Maße das Waschergebnis, da sich das Flüssigwaschmittel nicht gleichmäßig in der Waschmaschinentrommel verteilt, sondern in großem Maße am Boden oder in der Ablaufvorrichtung der Wasch­maschine anreichert. Dies kann weiterhin zur Folge haben, daß von den Anwendern mehr Flüssigwaschmittel als notwendig in die Einspülrinne eindosiert wird, was das Waschverfahren weniger wirtschaftlich und weniger umweltverträglich werden läßt.Since the induction troughs of commercially available washing machines are now designed to hold washing powder, considerable difficulties arise for the use of liquid products, in particular liquid detergents, in washing machines. In contrast to washing powder, which is gradually rinsed into the washing drum with the incoming water in the induction troughs of washing machines and also dissolves evenly there, liquid detergent either flows immediately into the washing machine or is immediately rinsed into the washing machine with the incoming water. This affects the washing result to a considerable extent, since the liquid detergent is not distributed evenly in the washing machine drum, but rather accumulates to a large extent on the floor or in the drain device of the washing machine. This can also have the consequence that more liquid detergent than necessary is metered into the induction channel by the users, which makes the washing process less economical and less environmentally compatible.

Ferner läßt sich Flüssigwaschmittel in den üblichen Einspülrinnen von Waschmaschinen im Gegensatz zu Waschpulver nicht für den Vor- und Hauptwaschgang bevorraten bzw. speichern.Furthermore, liquid detergents can be found in the usual induction channels washing machines, in contrast to washing powder, do not store or store them for the pre-wash and main wash cycle.

Zur Beseitigung dieser Schwierigkeiten ist in der DE-OS 35 12 083 eine kugelförmige Vorrichtung vorgeschlagen worden, die auf die Wäsche in der Waschmaschinentrommel gegeben wird und während des Waschvorganges nach und nach das Waschmittel abgibt. Diese Vorrichtung weist die Nachteile auf, daß zum einen die Wäsche mit dem konzentrierten Flüssigwaschmittel in Berührung kommt, so­daß die Gefahr besteht, daß nach Beendigung des Waschvorgan­ges Waschmittelreste in der Wäsche verbleiben oder fleckartig aufgehellte Stellen auf den gewaschenen Textilien entstehen. Zum anderen ist diese Vorrichtung für die Verwendung bei Zweilau­genverfahren, beispielsweise bei Vor- und anschließendem Klar­waschgang, nicht geeignet, da aufgrund der unverschlossenen Vorrichtung immer Flüssigwaschmittel aus der Vorrichtung in die Waschtrommel austritt, solange in der Vorrichtung noch Flüssig­waschmittel enthalten ist.To eliminate these difficulties, a spherical device has been proposed in DE-OS 35 12 083, which is placed on the laundry in the washing machine drum and gradually releases the detergent during the washing process. This device has the disadvantages that, on the one hand, the laundry comes into contact with the concentrated liquid detergent, so that there is the risk that after the washing process, detergent residues remain in the laundry or spots that are lightened like spots on the washed textiles. On the other hand, this device is not suitable for use in two-eye processes, for example in the case of a preliminary and subsequent rinse cycle, since liquid detergent always escapes from the device into the washing drum due to the unlocked device, as long as liquid detergent is still contained in the device.

Ferner ist aus der DE-PS 21 50 586 eine Vorrichtung zum Kon­ditionieren von Geweben in Trommeltrockenmaschinen bekannt. Hierbei handelt es sich aber um ein anwendungstechnisch völlig anderes Gebiet, da hier Konditionierungsmittel, wie Weich­macherverbindungen, der Wäsche zugegeben werden sollen, ohne daß diese Konditionierungsmittel dem Wasch- oder Spülwasser zugeführt oder in diesem gleichmäßig verteilt werden sollen. Insbesondere sieht diese Vorrichtung keinen innenliegenden Hohlraum zur Aufnahme von Flüssigprodukt vor, aus dem dann das Flüssigprodukt durch die Wandung hindurch aus der Vor­richtung abgegeben wird.Furthermore, from DE-PS 21 50 586 a device for conditioning fabrics in drum drying machines is known. However, this is a completely different field in terms of application technology, since conditioning agents, such as plasticizer compounds, are to be added to the laundry without these conditioning agents being added to the washing or rinsing water or being evenly distributed therein. In particular, this device does not provide an internal cavity for receiving liquid product, from which the liquid product is then discharged through the wall out of the device.

Aufgabe der Erfindung ist die Schaffung einer Lösung, die eine portionierte Bevorratung von Flüssigprodukt, insbesondere Flüssigwaschmittel, in der Einspülrinne von Waschmaschinen und dessen allmähliche und gleichmäßige Abgabe in das in eine Wasch­maschine einfließende Wasser ermöglicht.The object of the invention is to provide a solution which provides a portioned storage of liquid product, in particular liquid detergent, in the washing machine's washing trough allows its gradual and even release into the water flowing into a washing machine.

Bei einer Vorrichtung der eingangs bezeichneten Art wird die Aufgabe gemäß der Erfindung durch einen porösen, insbesondere wannen- oder tütenförmigen Einsatz zum Einbringen in die Ein­spülrinne von Waschmaschinen gelöst.In the case of a device of the type described at the outset, the object is achieved according to the invention by a porous, in particular trough-shaped or bag-shaped insert for insertion into the washing machine's washing trough.

Mit der erfindungsgemäßen Vorrichtung wird eine Dosierhilfe ge­schaffen, die nach Befüllung mit dem Flüssigprodukt dieses all­mählich und gleichmäßig an das einfließende Waschwasser abgibt. Dadurch wird das Flüssigprodukt gleichmäßig in der Waschlauge verteilt, und es besteht nicht mehr die Gefahr, daß sich Flüssig­produkt am Boden oder in der Ablaufvorrichtung der Waschmaschine absetzt. Weiterhin gelangt die Wäsche nicht mit Flüssigwaschmittel in konzentrierter Form in Berührung, so daß keine aufgehellten Flecken entstehen können, und kann die Vorrichtung mit einer Produktmenge, die ausreichend für ein Zweilaugenverfahren ist, befüllt werden. Durch die Ausbildung und Anordnung der erfin­dungsgemäßen Vorrichtung in der Einspülrinne einer Waschmaschine gelangt nur noch Flüssigprodukt in die Waschtrommel, wenn auch Waschwasser zufließt. Somit ist auch eine für die Durchführung eines Zweilaugenverfahrens ausreichende Bevorratung von Flüssig­waschmittel möglich.With the device according to the invention, a dosing aid is created which, after filling with the liquid product, releases it gradually and uniformly into the inflowing washing water. As a result, the liquid product is evenly distributed in the wash liquor and there is no longer any risk that liquid product will settle on the floor or in the drain device of the washing machine. Furthermore, the laundry does not come into contact with liquid detergent in a concentrated form, so that no brightened stains can occur, and the device can be filled with a product quantity which is sufficient for a two-eye process. Due to the design and arrangement of the device according to the invention in the induction channel of a washing machine, only liquid product gets into the washing drum when washing water also flows in. This means that a sufficient amount of liquid detergent can be stored to carry out a two-eye process.

In Ausgestaltung sieht die Erfindung vor, daß die Wandungen des Einsatzes aus offenzelligem Schaumstoff, Filterpapier oder Vlies­stoff bestehen. Diese Materialien besitzen eine ausreichend große Eigensteifigkeit zur Bildung des wannen- oder tütenförmigen Ein­satzes und weisen eine Porosität auf, die das allmähliche und gleichmäßige Durchdringen und Ausfließen des Flüssigproduktes gewährleisten.In an embodiment, the invention provides that the walls of the insert consist of open-cell foam, filter paper or nonwoven. These materials have a sufficiently high inherent stiffness to form the trough-shaped or bag-shaped insert and have a porosity which ensures the gradual and uniform penetration and outflow of the liquid product.

Weiterhin ist es vorteilhaft, wenn die Wandungen des Einsatzes in ihrer Porosität derart ausgelegt sind, daß die porösen Wandungen sowohl von Wasser als auch von verdünntem Flüssigprodukt durchdringbar sind, wie dies die Erfindung weiterhin vorsieht. Durch das in den porösen Einsatz eindringende Wasser wird die Viskosität des in dem Einsatz befindlichen Flüssigproduktes herabgesetzt, so daß ein allmähliches und restloses Austreten des Flüssigproduktes aus dem Einsatz erfolgen kann.Furthermore, it is advantageous if the walls of the insert are designed in their porosity in such a way that the porous walls Both water and dilute liquid product can be penetrated, as the invention further provides. The viscosity of the liquid product in the insert is reduced by the water penetrating into the porous insert, so that the liquid product can gradually and completely emerge from the insert.

Zweckmäßig ist es hierbei, daß der offenzellige Schaumstoff eine Rohdichte von 10 bis 100 kg/m³ und ein Porenvolumen von über 80 % aufweist, wie dies die Erfindung ebenfalls vorsieht.It is expedient here that the open-cell foam has a bulk density of 10 to 100 kg / m³ and a pore volume of over 80%, as is also provided by the invention.

Zweckmäßig ist es weiterhin, daß die Wandungen ganzheitlich porös ausgebildet sind, wie dies die Erfindung ebenfalls vorsieht. Durch diese Ausbildung wird die größtmögliche Austrittsfläche für das Flüssigprodukt geschaffen.It is furthermore expedient for the walls to be designed to be entirely porous, as is also provided by the invention. This design creates the largest possible outlet area for the liquid product.

Bei einem Verfahren zur portionierten Bevorratung und allmäh­lichen Abgabe von Flüssigprodukt, insbesondere Flüssigwasch­mittel, in das Waschwasser einer Waschmaschine wird die oben genannte Aufgabe gemäß der Erfindung dadurch gelöst, daß in die Einspürinne einer Waschmaschine ein poröser, wannen- oder tütenförmiger Einsatz eingebracht und mit Flüssigprodukt gefüllt sowie anschließend der Waschvorgang gestartet wird.In a method for portioned storage and gradual release of liquid product, in particular liquid detergent, into the washing water of a washing machine, the above-mentioned object is achieved according to the invention in that a porous, tub-shaped or bag-shaped insert is introduced into the washing machine groove and filled with liquid product and then the washing process is started.

In Ausgestaltung sieht die Erfindung vor, daß ein wannenförmiger Einsatz mit Wandungen aus offenzelligem Schaumstoff oder ein tütenförmiger Einsatz mit Wandungen aus Filterpapier oder Vliesstoff eingebracht wird. Zum einen sind aus fertigungstech­nischen Gründen aus offenzelligem Schaumstoff wannenförmige und aus Vliesstoff oder Filterpapier tütenförmige Einsätze besonders geeignet, da diese jeweils ohne großen und komplizierten tech­nischen Aufwand herstellbar sind und in der beschriebenen räumlichen Form die notwendige Eigensteife und Widerstands­fähigkeit gegen das Waschwasser aufweisen. Zum anderen sind diese Raumformen zum Einbringen in die Einspülrinnen von Wasch­maschinen besonders geeignet.In an embodiment, the invention provides that a trough-shaped insert with walls made of open-cell foam or a bag-shaped insert with walls made of filter paper or nonwoven is introduced. On the one hand, tub-shaped inserts made of open-cell foam and bag-shaped inserts made of nonwoven fabric or filter paper are particularly suitable for production-technical reasons, since they can each be produced without great and complicated technical effort and, in the spatial form described, have the necessary inherent stiffness and resistance to the wash water. On the other hand these spatial shapes are particularly suitable for insertion into the washing machine's washing troughs.

Schließlich sieht die Erfindung zweckmäßigerweise vor, daß Einsätze mit Wandungen aus offenzelligem Schaumstoff oder Vliesstoff mehrfach wiederverwendet werden.Finally, the invention expediently provides that inserts with walls made of open-cell foam or nonwoven are reused several times.

Die Erfindung ist nachstehend anhand der Zeichnung beipielsweise näher erläutert. Diese zeigt in perspektivischer Darstellung in

  • Fig. 1 einen wannenförmigen Einsatz und in
  • Fig. 2 einen tütenförmigen Einsatz.
The invention is explained below with reference to the drawing, for example. This shows in perspective in
  • Fig. 1 shows a trough-shaped insert and
  • Fig. 2 shows a bag-shaped insert.

Die fünf den in der Figur 1 insgesamt mit 1 bezeichneten wan­nenförmigen Einsatz bildenden Wandungen 2, 3, 4, 5, 6 bestehend ganzheitlich aus porösem, offenzelligem Schaumstoff. Nach oben hin ist der Einsatz 1 offen. Der offenzellige Schaumstoff kann beispielsweise aus Polyurethan, modifiziertem Polyvinylalkohol, Imidschäumen oder Viskose hergestellt sein. Er weist eine Roh­dichte von 10 bis 100 kg/m³ und ein Porenvolumen von über 80 % auf.The five walls 2, 3, 4, 5, 6 forming the tub-shaped insert, which is denoted overall by 1 in FIG. 1, consist entirely of porous, open-cell foam. Insert 1 is open at the top. The open-cell foam can be made, for example, from polyurethane, modified polyvinyl alcohol, imide foams or viscose. It has a bulk density of 10 to 100 kg / m³ and a pore volume of over 80%.

Die Figur 2 zeigt einen insgesamt mit 7 bezeichneten Einsatz, dessen Wandungen 8, 9 aus Filterpapier bestehen. Die Wandungen 8, 9 sind an den Seitenflächen des tüten- oder couvertförmigen Einsatzes 7 durch Prägestreifen oder Verklebungen miteinander verbunden. Das Filterpapier weist ein Gewicht von 84 g/m² und eine Filtrationszeit von 1500 s (Prüfsystem Herzberg) auf.FIG. 2 shows an insert, designated overall by 7, whose walls 8, 9 consist of filter paper. The walls 8, 9 are connected to one another on the side surfaces of the bag-shaped or envelope-shaped insert 7 by means of embossed strips or adhesives. The filter paper has a weight of 84 g / m² and a filtration time of 1500 s (Herzberg test system).

Sowohl der Einsatz 1 als auch der Einsatz 7 kann auch aus Vliesstoff gefertigt sein.Both the insert 1 and the insert 7 can also be made of nonwoven.

In ihrer Dimensionierung sind die Einsätze 1 und 7 auf die Flüssigproduktmenge, die sie in ihren Innenräumen 11 oder 12 aufnehmen sollen und die Abmessungen üblicher Einspülrinnen von Waschmaschinen, in welche sie eingesetzt werden sollen, abge­stimmt.In terms of their dimensions, the inserts 1 and 7 are matched to the amount of liquid product that they are to hold in their interior spaces 11 or 12 and the dimensions of conventional washing-in troughs in washing machines in which they are to be used.

Die Porosität des Einsatzes 1 oder 7 ist derart auf das Flüssig­produkt abgestimmt, daß unverdünntes oder konzentriertes Flüs­sigprodukt nicht, durch den Eintritt von Wasser verdünntes Flüssigprodukt aber gleichwohl durch die Wandungen austreten kann.The porosity of the insert 1 or 7 is matched to the liquid product in such a way that undiluted or concentrated liquid product cannot, but liquid product diluted by the entry of water can nevertheless escape through the walls.

Die Einsätze 1 oder 7 werden im Anwendungsfall in die Einspül­rinne von Waschmaschinen eingebracht und ihre Innenräume 11 und 12 werden mit Flüssigprodukt befüllt. Nach dem Einschalten des Waschvorganges und dem Eindringen von Wasser in die Innen­räume 11, 12, wodurch das darin befindliche Flüssigwaschmittel verdünnt wird, tritt das Flüssigprodukt dann allmählich und gleichmäßig durch die porösen Wandungen 2 bis 6 bzw. 8 und 9 in das in der Einspülrinne der Waschmaschine fließende Wasch­wasser aus.The inserts 1 or 7 are introduced into the washing machine's washing-in trough and their interiors 11 and 12 are filled with liquid product. After switching on the washing process and the penetration of water into the interior 11, 12, whereby the liquid detergent contained therein is diluted, the liquid product then gradually and evenly through the porous walls 2 to 6 or 8 and 9 in the in the induction channel of Washing machine flowing wash water out.

Die Priorität der Wandungen kann aber auch so ausgelegt sein, daß auch unverdünntes Flüssigwaschmittel langsam und allmählich austreten kann.The priority of the walls can also be designed so that even undiluted liquid detergent can escape slowly and gradually.
