Description

Automatisch gesteuerte Waschmaschine Automatically controlled washing machine
[0001 ] Die Erfindung betrifft eine automatisch gesteuerte Waschmaschine mit einer im oberen Maschinenraum angeordneten Waschmitteleinspüleinrichtung, die eine von vorn zugängli- che Schublade mit mindestens einer Kammer für eine handdosierte Zugabe einer Waschpulveroder Waschflüssigkeitsportion enthält, mit mindestens einer im oberen Maschinenraum angebrachten Vorratseinrichtung für flüssige oder gelförmige Waschhilfsmittel und mit je einer Einrichtung zum automatischen Dosieren jedes bevorrateten Waschhilfsmittels.[0001] The invention relates to an automatically controlled washing machine having a detergent dispensing device arranged in the upper machine room, which contains a drawer accessible from the front and having at least one chamber for a hand-dose addition of a washing powder or washing liquid portion, with at least one storage device for liquid or liquid in the upper machine room gel detergent and each with a means for automatically dosing each stored detergent.
[0002] Eine solche Waschmaschine ist aus der DE 32 34 058 A1 bekannt. Darin mündet die mit einer Dosiereinrichtung versehene Ablaufleitung der Vorratseinrichtung in eine Vor- mischkammer, die im unteren Maschinenraum in eine Umflutleitung integriert ist, in der bei bewegter Wäschetrommel Waschflüssigkeit von einem unteren Laugenbehälter-Ablauf ständig zu einer wenig höher liegenden Öffnung des Laugenbehälters transportiert wird. Unabhängig zu diesem dosierbaren Waschhilfsmittel kann von Hand dosiertes Waschmittel in bekannter Weise aus einer ebenfalls im oberen Maschinenraum untergebrachten Waschmitteleinspüleinrichtung dem Wäschebehandlungsprozess zugeführt werden.Such a washing machine is known from DE 32 34 058 A1. Therein, the drainage line of the storage device, which is provided with a metering device, opens into a premixing chamber, which is integrated in the lower machine room into a circulating line in which washing liquid is continuously transported from a lower tub outlet to a slightly higher opening of the tub when the washing drum is moved. Regardless of this metered detergent, manually metered detergent can be supplied to the laundry treatment process in a known manner from a likewise housed in the upper machine room Waschmitteleinspüleinrichtung.
[0003] In einer anderen bekannten Waschmaschine (DE 34 03 622 A1 ) ist in Zugrichtung einer Schublade hinter notorischen Waschmittelkammern, die zum Befüllen mit einzelnen Dosen von Waschpulvern oder Waschflüssigkeiten oben offen und von oben mittels Wasserstrah- len ausspülbar sind, ein Vorratsraum für flüssige Waschhilfsmittel angeordnet, der nach dem Aufbrauchen des Vorrats wieder befüllt werden muss. Dazu ist im Deckelbereich des Vorratsraumes eine Füllöffnung vorgesehen. Bei jeder Bewegung der Waschmittel-Schublade in eine Position zum Befüllen der Kammern wird mittels einer an der Schublade und ihrem Gehäuse angebrachten Mechanik eine bestimmte Dosis des bevorrateten Waschhilfsmittels aus dem Vorratsraum in eine Dosierkammer befördert, von wo sie während eines darauf folgendenIn another known washing machine (DE 34 03 622 A1) is in the direction of a drawer behind notorious detergent chambers, which are open for filling with individual doses of washing powders or washing liquids and rinsed from above by means of Wasserstrah- len, a reservoir for liquid Washing aid arranged, which must be refilled after the consumption of the stock. For this purpose, a filling opening is provided in the lid region of the storage space. With each movement of the detergent drawer to a position for filling the chambers, a certain dose of the stored washing aid is conveyed from the storage space into a metering chamber by means of a mechanism attached to the drawer and its housing, from where it is during a following
Waschprogrammablaufs mittels Wasser in den Laugenbehälter der Waschmaschine überführt werden kann.Washing program sequence can be converted by means of water in the tub of the washing machine.
[0004] Eine weitere bekannte Waschmaschine (DE 100 29 505 A1 ) enthält im oberen Maschinenraum unabhängig von der auf der anderen Seite eingebauten Waschmitteleinspülein- richtung einen Vorratsbehälter mit einer Dosierpumpe, die eine jeweils nach Messung der[0004] Another known washing machine (DE 100 29 505 A1) contains in the upper machine room, independently of the detergent dispensing device installed on the other side, a storage container with a metering pump, which in each case after measurement of the
Waschmittelkonzentration in der Waschflüssigkeit bemessene Menge von flüssigem Waschmittel unmittelbar in den Laugenbehälter überführt. Dabei ist vorgesehen, dass bei Beginn des Wasch prozesses etwa 50 % der benötigten Waschmittelmenge als Pulver oder Flüssigkeit aus der Waschmitteleinspüleinrichtung zusammen mit dem Zulaufwasser in den Laugenbehälter eingefüllt wird, ehe nach der oben erwähnten Messung mindestens eine zweite Menge Waschmittel aus dem Vorratsbehälter zugeführt wird.Detergent concentration in the washing liquid measured amount of liquid detergent transferred directly into the tub. It is envisaged that at the beginning of the washing process about 50% of the required amount of detergent as a powder or liquid the Waschmitteleinspüleinrichtung is filled together with the feed water in the tub, before after the above-mentioned measurement at least a second amount of detergent is supplied from the reservoir.
[0005] Ferner ist eine Waschmaschine bekannt (DE 25 54 592 C1 ), bei der anstelle einer konventionellen Waschmitteleinspüleinrichtung im oberen Maschinenraum eine Reihe von Vorratsbehältern für einzelne Komponenten von Waschmitteln bevorratet werden, aus denen sich die Steuerung der Waschmaschine für den aktuellen Waschprozess die jeweils benötigten Waschmittel-Komponenten selbsttätig bemisst und dem Waschprozess zu geeigneten Zeitpunkten zuführt. [0006] Solche Bevorratungen von Waschmitteln oder deren Komponenten und deren automatische Bemessung und Zuführung bedeuten für den Kunden eine erhebliche Arbeitserleichterung hinsichtlich des Nachschubs von Waschhilfsmitteln. In einigen bekannten Waschmaschinen ist die Füllöffnung zum Nachfüllen des Waschhilfsmittels an weniger gut zugänglichen Orten der Waschmaschine, z. B. unmittelbar oberhalb des Vorratsraumes, angeordnet, weshalb die gelegentlich erforderliche Wiederbefüllung beschwerlich ist, zumal die Füllöffnung des Vorratsraumes wegen der Gefahr des Überschwappens von Waschhilfsmittel während der Bewegung der Schublade nicht beliebig groß sein sollte, wenn die Füllöffnung nicht verschließbar ist. In anderen bekannten Waschmaschinen wird ein Austausch von Behältern gefordert, ohne dass besondere Aufmerksamkeit auf Lecks von Waschmittelresten gelegt wird. [0007] Der Erfindung liegt daher die Aufgabe zugrunde, eine eingangs genannte Waschmaschine so auszustatten, dass dem Kunden einerseits die Wahl für eine Handdosierung oder eine automatische Dosierung verbleibt, andererseits aber möglichst kurze Wege für ein automatisch dosiertes Waschhilfsmittel und Wartungsfreiheit für die Vorratseinrichtung bei Vermeidung von oben angesprochenen Nachteilen angestrebt werden. [0008] Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Kennzeichens im Anspruch 1 dadurch gelöst, dass die Vorratseinrichtung aus einer Aufnahmeeinrichtung für Waschhilfsmittel aus transportablen Vorratsbehältern gebildet ist, die an die Einrichtung zum automatischen Dosieren eines Waschhilfsmittels aus einem Vorratsbehälter fluidisch ankoppelbar ist, deren Austrittsöffnung in eine feststehende Kammer der Waschmitteleinspüleinrichtung mündet. Dadurch sind die Einrichtungen für die Bevorratung und Dosierung von flüssigem oder gelartigem Waschhilfsmittel konstruktiv so eng beieinander zu realisieren, dass die Forderungen der Aufgabenstellung erfüllt werden können. Gleichzeitig wird der Kunde auf diese Weise vom unmittelbaren Umgang und der Berührung mit dem Waschhilfsmittel befreit. [0009] Dadurch, dass die Austrittsöffnung in einer vorteilhaften Weiterbildung der Erfindung mittels einer Dosiereinrichtung in die feststehende Kammer mündet, kann die flüssige Waschhilfsmitteldosis ohne Leckverluste und Berührungsmöglichkeit durch den Kunden zwischengelagert und anschließend zu einem geeigneten Zeitpunkt durch zugeführtes Frischwasser wei- testgehend aus dieser Kammer ausgespült und dem Laugenbehälter der Waschmaschine auf konventionelle Weise zugeführt werden.Furthermore, a washing machine is known (DE 25 54 592 C1), in which instead of a conventional Waschmitteleinspüleinrichtung in the upper engine room a number of storage containers for individual components of detergents are stored, which make up the control of the washing machine for the current washing process each required detergent components automatically measures and feeds the washing process at appropriate times. Such inventories of detergents or their components and their automatic dimensioning and feeding mean a considerable amount of work for the customer with regard to the replenishment of washing aids. In some known washing machines, the filling opening for refilling the washing aid in less accessible places of the washing machine, for. B. immediately above the pantry, which is why the occasionally required refilling is cumbersome, especially since the filling opening of the pantry should not be arbitrarily large due to the risk of overflow of detergent during the movement of the drawer, if the filling opening is not closed. In other known washing machines, an exchange of containers is required without paying particular attention to leaks of detergent residues. The invention is therefore based on the object to equip a washing machine mentioned above so that the customer on the one hand the choice for a manual dosing or automatic dosing remains, but on the other hand, the shortest possible paths for an automatically metered detergent and maintenance freedom for the storage device while avoiding be sought from above disadvantages. According to the invention this object is achieved by the features of the characterizing part of claim 1, characterized in that the storage device is formed from a receiving device for washing aids from portable storage containers, which is fluidically coupled to the device for automatically dosing a washing aid from a reservoir, the outlet opening opens into a fixed chamber of Waschmitteleinspüleinrichtung. As a result, the facilities for the storage and dosage of liquid or gel detergent are structurally so close to realize that the requirements of the task can be met. At the same time, the customer is freed in this way from direct handling and contact with the washing aid. Characterized in that the outlet opening opens in an advantageous development of the invention by means of a metering device in the fixed chamber, the liquid detergent additive can be stored without leakage and touch possibility by the customer and then at a suitable time by supplied fresh water as far as possible from this chamber rinsed and supplied to the tub of the washing machine in a conventional manner.
[0010] In einer weiteren Fortbildung der Erfindung ist die Dosiereinrichtung in den Aufnahmeraum eingebaut. Vorteilhafterweise kann der Aufnahmeraum dann nämlich zugleich als ein Depot für transportfähige Vorratsbehälter dienen und die jeweilige Waschhilfsmitteldosis aus dem deponierten Vorratsbehälter leckfrei in die feststehende Kammer transportiert werden. Auf diese Weise wird keine Gefahr von Verschüttungen, Verunreinigungen, Verklebungen und nachfolgender Notwendigkeit der Reinigung gegeben sein, und der Kunde wird die erfindungsgemäße Waschmaschine ungetrübt gebrauchen können.In a further development of the invention, the metering device is installed in the receiving space. Advantageously, the receiving space can then serve at the same time as a depot for transportable storage containers and the respective detergent additive dose from the stored storage container can be transported leak-free into the fixed chamber. In this way, there will be no danger of spills, contamination, adhesions and subsequent need for cleaning, and the customer will be able to use the washing machine according to the invention without any obstruction.
[001 1] Vorzugsweise ist dazu die Saugseite der Dosiereinrichtung mit einem Kupplungsteil ver- sehen ist, das mit einem kongruenten Kupplungsteil am Vorratsbehälter verbindbar ist, wenn der Vorratsbehälter in den Aufnahmeraum eingesetzt wird. Die Druckseite der Dosiereinrichtung ist mit einer Verbindungsleitung zur feststehenden Kammer fest verbunden. Auf diese Weise kann der Kunde einen leeren Vorratsbehälter schadlos entnehmen und gegen einen neuen, noch vollen Vorratsbehälter austauschen. Es müssen dazu keine flexiblen Leitungen miteinan- der verbunden werden, deren Öffnungen vor dem Verbinden mit Waschhilfsmittelresten belastet sind. So wird der Kunde am besten vor der Kontamination durch Waschhilfsmittel geschützt, und außerdem können keine solchen Reste in die Waschmaschine tropfen und dadurch etwa Schäden auslösen.For this purpose, the suction side of the metering device is preferably provided with a coupling part which can be connected to a congruent coupling part on the storage container when the storage container is inserted into the receiving space. The pressure side of the metering device is firmly connected to a connecting line to the fixed chamber. In this way, the customer can remove an empty reservoir harmless and replace it with a new, still full reservoir. For this purpose, no flexible lines must be connected to one another, the openings of which are loaded with washing agent residues before being connected. Thus, the customer is best protected from contamination by detergents, and also can not drip such residues in the washing machine and thereby cause damage.
[0012] Vorteilhafterweise ist die feststehende Kammer ähnlich den mit der Schublade bewegli- chen Kammern von der Deckelseite des Gehäuses her mit Frischwasser beschickbar. Auf diese Weise kann die automatisch dosierte Menge an Waschhilfsmittel hervorragend zwischengelagert werden, bis die Steuereinrichtung der Waschmaschine durch Öffnen des zugeordneten Ventils diese Kammer mittels Frischwasser ausspülen lässt und über den allen Kammern gemeinsamen Ablaufschacht in den Laugenbehälter führt. [0013] Der oder die Vorratsbehälter sind gemäß einer Fortbildung der Erfindung in der Vorratseinrichtung unterhalb einer Deckplatte der Waschmaschine angeordnet, die zum Zwecke der Ergänzung des Vorrats an Waschhilfsmitteln angehoben werden kann. Diese Deckplatte kann die Arbeitsplatte der Waschmaschine an sich sein oder als Teil der Arbeitplatte eine Klappe bilden, die an einem Ausschnitt der Arbeitsplatte scharniert ist. [0014] Andernfalls kann die Vorratseinrichtung stattdessen eine Füllleitung aufweisen, die zum Zwecke des Nachfüllens von Wasch hilfsmittel an der Frontseite der Waschmaschine, vorzugsweise im Bereich der Bedienungsblende, mündet. Alternativ kann der Zugang zur Vorratseinrichtung durch eine Tür oder Klappe ermöglicht werden, die in der Frontseite angeordnet ist und zum Zwecke des Austauschens von Vorratsbehältern geöffnet werden kann.Advantageously, similar to the chambers movable with the drawer, the fixed chamber can be charged with fresh water from the cover side of the housing. In this way, the automatically metered amount of detergent can be stored well until the control device of the washing machine can be rinsed by opening the associated valve, this chamber using fresh water and over the common chambers all the way down the drain into the tub. The one or more reservoirs are arranged according to a development of the invention in the storage device below a cover plate of the washing machine, which can be raised for the purpose of supplementing the supply of washing aids. This cover plate may be the worktop of the washing machine itself or form part of the worktop a flap which is hinged to a section of the worktop. Otherwise, the storage device may instead have a filling line, the aid for the purpose of refilling of washing on the front of the washing machine, preferably in the region of the control panel, opens. Alternatively, access to the storage means may be provided by a door or flap located in the front and openable for the purpose of exchanging storage containers.
[0015] Die Merkmale der Unteransprüche können in beliebiger Kombination untereinander oder mit den Merkmalen des Hauptanspruches kombiniert werden, ohne die Erfindung zu verlassen.The features of the subclaims can be combined in any combination with each other or with the features of the main claim, without departing from the invention.
[0016] Anhand von in der Zeichnung dargestellten Ausführungsbeispielen ist die Erfindung näher erläutert.

Die Weichspülkammer 10 hat noch einen Saugheber 11 (schematisch dargestellt). Die hinteren Enden der Kammern 8 und 9 sowie der Saugheber 1 1 münden in einen gemeinsamen Ablaufschacht 12, der die Gemische aus Waschhilfsmittel und Wasser, das von oben in die Kammern geleitet werden kann, in nicht dargestellter Weise zum Laugenbehälter 2 führt. In diesen Raum kann eine oder können mehrere Dosierleitungen 23, 24 aus Vorratsbehältern 19, 20 für Waschhilfsmittel münden (hier nicht dargestellt), die im oberen Raum der Waschmaschine außerhalb der Waschmitteleinspüleinrichtung angeordnet sind. Für eine solche Anbringung von Vorratsbehältern 19, 20 ist diese Lösung vorteilhaft, weil keine weiteren Einrichtungen für die Führung der Waschhilfsmitteldosen vorgesehen sein müssen.Fig. 2 shows another single storage device for a washing machine according to the invention equipped with a device for automatically dosing a portion of the stored amount of washing aid. The housing 1 of the washing machine surrounds a tub 2, which extends in the housing 1 so far up that for the Waschmitteleinspüleinrichtung 3 is only the upper side remaining space within the housing 1 is available. The Waschmitteleinspüleinrichtung 3 has its own housing box 4, which extends from the front panel 1.1 of the housing 1 to its rear wall 1.2 and in which the drawer 5 is guided freely movable in the pulling direction 6 and in the direction of thrust 7. The drawer 5 has three open-top detergent chambers 8, 9 and 10 for pre-wash (8), main wash (9) and fabric softener (10). The fabric softening chamber 10 also has a siphon 11 (shown schematically). The rear ends of the chambers 8 and 9 and the siphon 1 1 open into a common downcomer 12, which leads the mixtures of washing aid and water, which can be passed from above into the chambers in a manner not shown to the tub 2. In this space, one or more dosing lines 23, 24 from reservoirs 19, 20 open for washing aids (not shown here), which are arranged in the upper space of the washing machine outside the Waschmitteleinspüleinrichtung. For such an attachment of storage containers 19, 20, this solution is advantageous because no further means for the guidance of the detergent additive cans must be provided.
[0018] Eine andere Lösung zeigt Fig. 1 . Darin ist hinter dem Schacht 12 außerhalb der Schublade mindestens eine feststehende Kammer 13 für eine Dosis eines flüssigen oder gelförmigen Waschhilfsmittels im Gehäuse 4 der Waschmitteleinspüleinrichtung 3 integriert. Die Kammer bzw. Kammern 13 sind in ihrer Form und Größe dem jeweiligen hinter den Kammern 8 bis 10 der Schublade 5 noch zur Verfügung stehenden Raum angepasst und bleiben im Gehäuse 4 in jedem Falle ortsfest, auch wenn die Schublade 5 bewegt wird. Bei Unterbringung einer einzigen Kammer 13 im Gehäuse 4 kann eine Dosis von bis zu 500 ml Waschhilfsmittel bevorratet wer- den.Another solution is shown in FIG. 1. Therein, at least one fixed chamber 13 for a dose of a liquid or gel detergent in the housing 4 of the Waschmitteleinspüleinrichtung 3 is integrated behind the shaft 12 outside the drawer. The chamber or chambers 13 are adapted in their shape and size to the respective behind the chambers 8 to 10 of the drawer 5 still available space and remain stationary in the housing 4 in any case, even if the drawer 5 is moved. When accommodating a single chamber 13 in the housing 4, a dose of up to 500 ml of washing aid can be stored.
[0019] Am Boden hat die Kammer 13 eine Ablauföffnung 14 mit einem Saugheber 15 wie die Kammer 10 für Weichspülmittel. Bei der Anordnung mehrerer Kammern 13 sind natürlich entsprechend viele Saugheber 15 mit Ablauföffnungen 14 vorzusehen, die alle in denselben Ablaufschacht 12 münden. [0020] Im rückwärtigen Bereich des Gehäusekastens 4 kann noch eine Magnetventil- Baugruppe 16 für die Beschickung der Kammern 8 bis 10 und 12 angeordnet sein. Für die Beschickung aller Kammern mit Frischwasser aus dem jeweils zugehörigen Magnetventil sind in bekannter Weise im Deckenbereich des Gehäuses 4 der Waschmitteleinspüleinrichtung 3 Führungskanäle und Sprühdüsen angeordnet (nicht dargestellt), so dass immer nur die jeweilige Kammer mit dem zugeordneten Frischwasserstrom beaufschlagt wird. Die Magnetventil- Baugruppe 16 wird dazu über einen zentralen Zulauf 17 aus einem nicht dargestellten Hauswassernetz mit Frischwasser versorgt.At the bottom, the chamber 13 has a drain opening 14 with a siphon 15 as the chamber 10 for fabric softener. In the arrangement of several chambers 13, of course, a corresponding number of siphon 15 are provided with drain openings 14, all of which open into the same downcomer 12. In the rear region of the housing box 4, a solenoid valve assembly 16 may still be arranged for the loading of the chambers 8 to 10 and 12. For the loading of all chambers with fresh water from the respectively associated solenoid valve 3 guide channels and spray nozzles are arranged in a known manner in the ceiling region of the housing 4 of the Waschmitteleinspüleinrichtung (not shown), so that only the respective chamber with the associated fresh water flow is applied. The solenoid valve assembly 16 is supplied via a central inlet 17 from a domestic water supply, not shown, with fresh water.
[0021] Auf der rechten Seite des oberen Bauraums innerhalb des Maschinengehäuses 1 wird der dort vorhandene freie Raum von einer Vorratseinrichtung 18 ausgefüllt, die einen oder - wie hier dargestellt - zwei Vorratsbehälter 19 und 20 beherbergen kann. Jedem Vorratsbehälter ist eine Dosiereinrichtung 21 , 22 zugeordnet, die im Wesentlichen eine Pumpe umfasst. Die Saugseite jeder Pumpe kommuniziert mit dem Innenraum des zugeordneten Vorratsbehälters 19, 20 und die Druckseite jeder Pumpe mit einer zugeordneten Verbindungsleitung 23 bzw. 24. Diese Leitungen 23 und 24 münden - hier gemeinsam - in die Kammer 13, was unschädlich ist, wenn die zweite Dosiereinrichtung 22 erst angesprochen wird, nachdem die in der Kammer 13 zwischengelagerte Dosis des Waschhilfsmittels aus dem ersten Vorratsbehälter 19 schon ausgespült worden ist. Sind dagegen zwei feststehende Kammern vorgesehen, dann kann jede der Verbindungsleitungen 23 und 24 in je einer der Kammern münden.On the right side of the upper space within the machine housing 1 of the available space there is filled by a storage device 18, the one or - as shown here - can accommodate two reservoirs 19 and 20. Each storage container is associated with a metering device 21, 22, which essentially comprises a pump. The suction side of each pump communicates with the interior of the associated reservoir 19, 20 and the pressure side of each pump with an associated connecting line 23 and 24. These lines 23 and 24 open - here together - in the chamber 13, which is harmless when the second Dosing 22 is addressed only after the intermediate stored in the chamber 13 dose of the washing aid from the first reservoir 19 has already been rinsed. If, on the other hand, two fixed chambers are provided, then each of the connecting lines 23 and 24 can open into one of the chambers.
[0022] Jeder der Vorrastbehälter 19 und 20 hat eine Nachfüllöffnung bzw. -leitung 25 bzw. 26, durch die er bei Bedarf aufgefüllt werden kann. Dazu hat die Waschmaschine oberhalb der Vorratseinrichtung 18 eine hier nicht dargestellte Klappe, die vor dem Nachfüllen geöffnet werden muss. Alternativ kann auch jeder Vorratsbehälter 19 und 20 mit je einer Füllleitung versehen sein, deren Einfüllöffnung hinter einer Tür oder Klappe der frontseitigen Bedienungsblende versteckt ist. Diese Alternative ist hier ebenfalls nicht dargestellt. [0023] Fig. 2 zeigt eine andere Variante der Bevorratung von Waschhilfsmitteln. Dazu ist anstelle eines fest eingebauten Vorratsbehälters 19 oder 20 in Fig. 1 eine Aufnahmeeinrichtung 27 für einen Vorratsbehälter 28 vorgesehen, der ein transport- und handelsfähiger Vorratsbehälter sein und von einem Waschmittelhersteller vertrieben werden kann. In der Aufnahmeeinrichtung 27, die einen kastenförmigen Raum bildet, ist eine Dosiervorrichtung 21 angeordnet, an deren Saugseite 29 ein Kupplungsteil 30 angeschlossen ist. Mit der Druckseite 31 ist die Dosiervorrichtung 21 an die Verbindungsleitung 23 angeschlossen.Each of the Vorrastbehälter 19 and 20 has a refill opening or line 25 and 26, through which it can be filled if necessary. For this purpose, the washing machine above the storage device 18 has a flap, not shown here, which must be opened before refilling. Alternatively, each reservoir 19 and 20 may each be provided with a filling line whose filling opening is hidden behind a door or flap of the front panel. This alternative is also not shown here. Fig. 2 shows another variant of the storage of washing aids. For this purpose, instead of a permanently installed storage container 19 or 20 in FIG. 1, a receiving device 27 is provided for a storage container 28, which can be a transportable and marketable storage container and can be distributed by a detergent manufacturer. In the receiving device 27, which forms a box-shaped space, a metering device 21 is arranged on the suction side 29, a coupling member 30 is connected. With the pressure side 31, the metering device 21 is connected to the connecting line 23.
[0024] Auf das saugseitige Kupplungsteil 30 passt ein an den Boden des Vorratsbehälters 28 angebrachtes Gegenteil 32, das beim Einsetzen des Vorratsbehälters 28 (entsprechend der Bewegung entlang des Pfeils 33) dicht an das Kupplungsteil 30 anschließt. Die größeren flächigen Wandungen des Vorratsbehälters 28 haben versteifende Sicken 34, damit der Vorratsbehälter auf seinem Transportwege eine stabile Form behält. Zum maschinellen Lesen seines Inhaltes und anderer Informationen ist an einer gut zugänglichen Stelle ein Identifikationsschild 35 angebracht. [0025] Die Konstruktion der Dosiereinrichtungen 21 , 22 ist nicht näher dargestellt. Sie kann entweder gemäß dem Stand der Technik aus DE 34 03 622 A1 oder in einer anderen Weise mit Fördereinrichtungen (Magnetventil, Pumpe, Verschlussschieber) für den Waschhilfsmittelvorrat aus dem Vorratsbehälter 19 bzw. 20 (Fig. 1 ) oder 28 (Fig. 2) entweder drucklos oder unter Druckbeaufschlagung ausgebildet sein. On the suction-side coupling part 30 fits an attached to the bottom of the reservoir 28 opposite 32, which connects at the onset of the reservoir 28 (corresponding to the movement along the arrow 33) close to the coupling part 30. The larger planar walls of the reservoir 28 have stiffening beads 34 so that the reservoir retains a stable shape on its transport routes. For machine reading its contents and other information an identification plate 35 is attached to a well-accessible location. The construction of the metering devices 21, 22 is not shown in detail. It can either according to the prior art from DE 34 03 622 A1 or in another way with conveyors (solenoid valve, pump, shutter) for the washing aid supply from the reservoir 19 or 20 (Fig. 1) or 28 (Fig. 2) be designed either pressureless or pressurized.
