Description

Die Erfindung geht aus von einer Wasch- oder Spülmaschine mit Einrichtungen zum automatischen Dosieren von flüssigen Wasch- oder Spülmittel-Wirkstoffen aus einer Mehrzahl von diese Wirkstoffe bevorratenden Behältern, die über Nachfüll-Öffnungen aus Transportbehältern bestimmter Volumina befüllt werden können.The invention relates to a washing machine or dishwasher with devices for the automatic dosing of liquid detergent or dishwashing agents from a plurality of containers storing these agents, which can be filled via refill openings from transport containers of certain volumes.

Eine derartige Waschmaschine ist aus der DE-OS 25 54 592 bekannt. Darin ist vor­gesehen, die Volumina der Vorratsbehälter in einem Maß zu staffeln, das dem durchschnittlichen Anteil an der Benutzungshäufigkeit der darin bevorrateten Wirk­stoffe entsprechen soll. Als ein Beispiel der Staffelung ist dort angegeben, 8 : 4 : 2 : 1 : 1 : 1. Die Häufigkeit der Benutzung von einzelnen Wirkstoffen be­mißt sich im Durchschnitt an je Waschgang unterschiedlichen Mengen. Diese Mengen sind abhängig von der Konzentration und dem Effekt der einzelnen Wirkstoffe sowie dem Aufbau des gesamten Wirkstoffsystems, der Art der gewählten Waschprogram­me, der Wasserhärte und den Waschgewohnheiten im jeweiligen Haushalt.Such a washing machine is known from DE-OS 25 54 592. It is provided that the volumes of the storage containers are staggered to such an extent that they should correspond to the average share in the frequency of use of the active ingredients stored therein. As an example of the staggering, 8: 4: 2: 1: 1: 1 is given there. The frequency of the use of individual active substances is measured on average by different amounts per washing cycle. These amounts depend on the concentration and the effect of the individual active ingredients as well as the structure of the entire active ingredient system, the type of washing program selected, the water hardness and the washing habits in the respective household.

Indessen hat es sich als nicht sehr sinnvoll erwiesen, die Abstufung der Behälter-­Volumina nach dieser Überlegung vorzunehmen. Infolge einiger der vorstehend be­schriebenen Einflußgrößen sind die Verbrauchswerte der einzelnen Wirkstoffe von Haushalt zu Haushalt gewissen Schwankungen unterworfen. Einen hierfür zugrundege­legten durchschnittlichen Haushalt gibt es daher nur theoretisch. D.h., in der Praxis führt die vorgesehene Abstufung fast nie zum gewünschten gleichzeitigen Verbrauch aller Wirkstoffe, die entsprechend gleichzeitig in vollem Umfange zu ersetzen wären.However, it has not proven to be very sensible to graduate the container volumes after this consideration. As a result of some of the influencing variables described above, the consumption values of the individual active ingredients are subject to certain fluctuations from household to household. An average household on which this is based is therefore only theoretical. That is, in practice, the intended gradation almost never leads to the desired simultaneous consumption of all active substances, which would accordingly have to be replaced in full at the same time.

Der Erfindung liegt die Aufgabe zugrunde, bei einer eingangs genannten Waschma­schine eine sinnvollere Bemessung der Behälter-Volumina vorzunehmen.The invention is based, to make a more sensible dimensioning of the container volumes in a washing machine mentioned at the outset.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Behälter-Volumina ein einfaches oder ein ganzzahliges Vielfaches des Volumens des jeweils zugeordneten Transportbehälters betragen.According to the invention, this object is achieved in that the container volumes are a single or an integral multiple of the volume of the respectively assigned transport container.

Die erfindungsgemäße Bemessung hat den Vorteil, daß bei einer Mangelmeldung aus einem Vorratsbehälter immer mindestens ein Transportbehälter vollständig in den Vorratsbehälter entleert werden kann. Dadurch bleiben im Haushalt keine teilweise gefüllten Transportbehälter im Wege stehen. Weiterer Vorteil ist eine einfachere Lagerung der Transportbehälter, die in Größe und Form normiert sein können und sich daher sowohl bei der Befüllung im Herstellerwerk für die Wirkstoffbehälter, wie auch beim Transport und der Lagerung auf den einzelnen Vertriebswegen platzspa­rend lagern und einfach handhaben lassen. Gleich große Transportbehälter sind au­ßerdem billiger in der Herstellung und belasten kostenmäßig daher den Wirkstoff­preis weniger.The dimensioning according to the invention has the advantage that in the event of a deficiency report from a storage container, at least one transport container can always be completely emptied into the storage container. This means that there are no partially filled transport containers in the way of the household. Another advantage is a simpler storage of the transport containers, which can be standardized in size and shape and can therefore be stored in a space-saving manner and easily handled both during filling in the manufacturer's plant for the active substance containers and during transport and storage on the individual distribution channels. Transport containers of the same size are also cheaper to manufacture and therefore cost less the drug price.

Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung weisen die Be­hälter zusätzlich ein Reserve-Volumen von etwa 1/10 ihres Hauptvolumens auf. Ein solches Reserve-Volumen ermöglicht dem Haushalt den rechtzeitigen Nachschub von Wirkstoffen, bevor ein Vorratsbehälter endgültig geleert ist.According to a particularly advantageous embodiment of the invention, the containers additionally have a reserve volume of approximately 1/10 of their main volume. Such a reserve volume enables the household to replenish active ingredients in good time before a storage container is finally emptied.

Eine weitere vorteilhafte Weiterbildung der Erfindung ergibt sich bei einer Wasch­maschine mit Behältern für Vollwaschmittel, Bleichmittel, Feinwaschmittel und Weichspülmittel dadurch, daß das Hauptvolumen der Behälter für Vollwaschmittel, Bleichmittel und Feinwaschmittel jeweils doppelt so groß und das Hauptvolumen des Behälters für Weichspülmittel so groß ist wie das des zugeordneten Transportbehäl­ters. Da der Unterbringung von Vorratsbehältern in einer Waschmaschine oder in ei­nem der Waschmaschine beistellbaren Dosiergerät gewisse räumliche Grenzen gesetzt sind, ist der Hersteller gehalten, den zur Verfügung stehenden Raum möglichst öko­nomisch auszunutzen. Dies kann am ehesten dadurch erreicht werden, daß möglichst viele der Vorratsbehälter gleich großes Volumen haben. Aneinandergereihte Behälter dieser Art ergeben dann einen quaderartigen Block, der beispielsweise in einem Bei­stellgerät sehr raumökonomisch unterbringbar ist. Außerdem ist auch hierbei die Herstellung gleich großer Vorratsbehälter mit einem Preisvorteil verbunden. Den Be­hälter für Weichspülmittel kann man allerdings kleiner ausführen, weil erfahrungs­gemäß Weichspülmittel weniger häufig benutzt wird. Bei einer größeren Lagermenge von Weichspülmittel als vorstehend beansprucht, wäre die Gefahr des Gelierens oder Kristallisierens während der dadurch verlängerten Lagerzeit zu groß.Another advantageous development of the invention results in a washing machine with containers for heavy-duty detergents, bleaches, mild detergents and Fabric softener in that the main volume of the container for heavy-duty detergent, bleach and mild detergent is twice as large and the main volume of the container for fabric softener is as large as that of the assigned transport container. Since the storage of storage containers in a washing machine or in a metering device which can be provided with the washing machine has certain spatial limits, the manufacturer is obliged to use the available space as economically as possible. This can best be achieved by having as many of the storage containers as possible have the same volume. Lined-up containers of this type then result in a cuboid block, which can be accommodated in a space-saving device, for example, in a very space-efficient manner. In addition, the production of storage containers of the same size is also associated with a price advantage. The container for fabric softener can be made smaller, however, because experience has shown that fabric softener is used less frequently. If the amount of fabric softener stored was greater than that claimed above, the risk of gelation or crystallization would be too great during the prolonged storage time.

Brauchbare Abmessungen für die Vorratsbehälter und für die Transportbehälter erge­ben sich dann, wenn gemäß einer weiteren vorteilhaften Ausbildung der Erfindung die Transportbehälter ein einheitliches Volumen von jeweils 3 l haben. Dann er­gibt sich für die Behälter für Vollwaschmittel, Bleichmittel und Feinwaschmittel ein Hauptvolumen von jeweils 6 l plus einem Reserve-Volumen von 1/10, also 0,6 l, ins­gesamt also 6,6 l. Das Hauptvolumen des Weichspülmittel-Behälters beträgt dann 3 l, das Gesamtvolumen (vermehrt um das Reserve-Volumen von 0,3 l) demnach 3,3 l. Ein einzelner Behälter, z.B. der Weichspülmittel-Vorratsbehälter, kann auch ein um einen Anteil des Transportbehälter-Volumens größeres Hauptvolumen haben. Bei­spielsweise kann das Hauptvolumen dieses Behälters 4 l betragen, also 3 l Trans­portbehälter-Volumen + 1/3 dieses Volumens. Bei einer Mangelmeldung aus diesem Vorratsbehälter würde dann in jedem Fall ein ganzer Transportbehälter in den Vor­ratsbehälter entleert werden können.Usable dimensions for the storage containers and for the transport containers result when, according to a further advantageous embodiment of the invention, the transport containers have a uniform volume of 3 l each. This results in a main volume of 6 l each plus a reserve volume of 1/10, i.e. 0.6 l, for a total of 6.6 l, for the containers for heavy-duty detergent, bleach and mild detergent. The main volume of the fabric softener container is then 3 l, the total volume (increased by the reserve volume of 0.3 l) accordingly 3.3 l. A single container, e.g. the fabric softener reservoir, can also have a larger main volume by a proportion of the transport container volume. For example, the main volume of this container can be 4 l, ie 3 l transport container volume + 1/3 of this volume. In the event of a deficiency report from this storage container, an entire transport container would then be able to be emptied into the storage container.
