Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Waschmaschine und eine Waschmaschine mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit, einer drehbar in dem Laugenbehälter gelagerten Trommel zur Aufnahme von Wäsche und einer eine Umflutpumpe aufweisenden Umfluteinrichtung zum Fördern der Waschflüssigkeit aus einem ersten Bereich des Laugenbehälters in einen zweiten Bereich des Laugenbehälters, wobei ein oder mehrere Waschmittel aus einer oder mehreren Dosiereinrichtungen in die Umfluteinrichtung in einer jeweils vorbestimmten Dosierung eingespeist werden können. Ein solches Verfahren bzw. eine solche Waschmaschine ist in der DE102014105711A1 beschrieben.The invention relates to a method for operating a washing machine and a washing machine with a tub for holding washing liquid, a drum rotatably mounted in the tub for holding laundry and a flooding device with a flooding pump for conveying the washing liquid from a first area of the tub into a second Area of the tub, wherein one or more detergents from one or more metering devices can be fed into the flooding device in a respectively predetermined dosage. Such a method or such a washing machine is in the DE102014105711A1 described.

Neben Einkomponenten-Waschmitteln, die als eine Komponente bzw. unverändert in den Laugenbehälter der Waschmaschine zum Waschen von Wäsche eingespeist werden, gibt es Mehrkomponenten-Waschmittel, bei denen mehreren Komponenten erst unmittelbar vor oder bei dem Einführen des Waschmittels in den Laugenbehälter zum Waschen von Wäsche gemischt werden. Es hat sich gezeigt, dass es vorteilhaft ist, verschiedene Komponenten eines Mehrkomponenten-Waschmittels erst unmittelbar vor dem Einsatz des Waschmittels zu mischen, um so eine Ausbeute an Aktivsubstanzen wie beispielsweise Bleichmittel zu erhöhen. Für ein Mischen von verschiedenen Waschmittel-Komponenten in konzentrierter Form ist es wünschenswert, dass die Waschmaschine eine Mischvorrichtung aufweist. Denkbar ist beispielsweise eine Mischstrecke oder eine Mischkammer für die mehreren Waschmittel-Komponenten. Dafür sind aber extra Bauteile nötig, und die Kosten werden erhöht. Es besteht daher ein Bedarf an einem Verfahren und einer Waschmaschine, die geeignet sind, konzentrierte Waschmittel-Komponenten zu mischen.In addition to single-component detergents, which are fed as one component or unchanged into the tub of the washing machine for washing laundry, there are multi-component detergents in which several components are only used immediately before or when the detergent is introduced into the tub for washing laundry be mixed. It has been shown that it is advantageous to mix various components of a multicomponent detergent only immediately before using the detergent in order to increase the yield of active substances such as bleach. For mixing different detergent components in concentrated form, it is desirable that the washing machine has a mixing device. For example, a mixing section or a mixing chamber for the multiple detergent components is conceivable. For this, however, extra components are required and the costs are increased. There is therefore a need for a method and a washing machine that are suitable for mixing concentrated detergent components.

Der Erfindung stellt sich somit das Problem ein Verfahren zum Betreiben einer Waschmaschine und eine Waschmaschine bereitzustellen, bei denen mehrere Waschmittel-Komponenten in der Waschmaschine mischbar sind.The problem addressed by the invention is thus to provide a method for operating a washing machine and a washing machine in which a plurality of detergent components can be mixed in the washing machine.

Erfindungsgemäß wird dieses Problem durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 und eine Waschmaschine mit den Merkmalen des Patentanspruchs 5 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a method with the features of patent claim 1 and a washing machine with the features of patent claim 5. Advantageous refinements and developments of the invention emerge from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen neben der Nutzung vorhandener Bauteile zur Herstellung des Waschmittels in situ in der Waschmaschine bzw. zum Mischen von Waschmittel-Komponenten darin, dass diese Lösung verfahrenstechnisch flexibel einsetzbar ist und an unterschiedlichen Waschmaschinen bzw. Waschmaschinenbauarten angepasst werden kann. Zudem sind keine weiteren wesentlichen raumbeanspruchenden Bauteile für die Waschmaschine als Mischkammer notwendig. Daher ist die Lösung kostengünstig.The advantages that can be achieved with the invention are, in addition to the use of existing components for producing the detergent in situ in the washing machine or for mixing detergent components, that this solution is flexible in terms of process technology can be used and adapted to different washing machines or washing machine types. In addition, no other essential space-consuming components for the washing machine as a mixing chamber are necessary. Hence the solution is inexpensive.

Die Erfindung betrifft ein Verfahren zum Betreiben einer Waschmaschine mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit und einer eine Umflutpumpe aufweisenden Umfluteinrichtung zum Fördern der Waschflüssigkeit aus einem ersten Bereich des Laugenbehälters in einen zweiten Bereich des Laugenbehälters, bei dem mindestens zwei Waschmittel-Komponenten aus einer oder mehreren Dosiereinrichtungen in die Umflutpumpe in einer jeweils vorbestimmten Dosierung eingespeist werden, und bei dem die Umflutpumpe bei und/oder nach dem Einspeisen der mindestens zwei Waschmittel-Komponenten bei einer Drehzahl unterhalb einer Förderdrehzahl betrieben wird, bei der die Waschflüssigkeit aus dem ersten Bereich des Laugenbehälters in den zweiten Bereich des Laugenbehälters gefördert wird, und bei dem die Umflutpumpe anschließend bei einer Drehzahl gleich zu oder oberhalb der Förderdrehzahl betrieben wird. Mittels Betreiben der Umflutpumpe bei und/oder nach dem Einspeisen der mindestens zwei Waschmittel-Komponenten bei einer Drehzahl unterhalb einer Förderdrehzahl wird ein Mischvorgang bewirkt, und mittels Betreiben der Umflutpumpe bei einer Drehzahl gleich zu oder oberhalb der Förderdrehzahl wird ein Umflutvorgang erwirkt. Durch die Nutzung der Umflutpumpe als Mischkammer kann die Mischkammer während des Umflutvorgangs gespült und die Waschmittellösung sicher in die Wäsche eingebracht werden.The invention relates to a method for operating a washing machine with a tub for receiving washing liquid and a circulating device having a circulating pump for conveying the washing liquid from a first area of the tub into a second area of the tub, in which at least two detergent components are composed of one or more Dosing devices are fed into the circulation pump in a predetermined dosage, and in which the circulation pump is operated during and / or after the at least two detergent components are fed in at a speed below a delivery speed at which the washing liquid from the first area of the tub in the second area of the tub is promoted, and in which the circulation pump is then operated at a speed equal to or above the delivery speed. By operating the circulating pump during and / or after feeding the at least two detergent components at a speed below a delivery speed, a mixing process is effected, and by operating the circulating pump at a speed equal to or above the delivery speed, a flooding process is achieved. By using the circulating pump as a mixing chamber, the mixing chamber can be rinsed during the circulating process and the detergent solution can be safely introduced into the laundry.

Dadurch, dass die Waschmittel-Komponenten in die Umflutpumpe dosiert werden und die Umflutpumpe bei einer Drehzahl unterhalb der Förderdrehzahl betrieben wird, werden die Waschmittel-Komponenten gemischt und anschließend wird das so erzeugte Komponenten-Gemisch durch Betreiben der Umflutpumpe bei einer Drehzahl gleich oder oberhalb der Förderdrehzahl ggf. zusammen mit sich in dem Laugenbehälter befindender Waschflüssigkeit in die Wäsche gefördert. Auf diese Weise können einerseits konzentrierte Waschmittel-Komponenten gemischt werden.Because the detergent components are dosed into the circulating pump and the circulating pump is operated at a speed below the delivery speed, the detergent components are mixed and then the component mixture thus generated is generated by operating the circulating pump at a speed equal to or above the Conveying speed, if necessary, conveyed into the laundry together with washing liquid in the tub. In this way, on the one hand, concentrated detergent components can be mixed.

Andererseits kann das erhaltene konzentrierte Gemisch durch Betreiben der Umflutpumpe bei einer Drehzahl gleich oder oberhalb der Förderdrehzahl in die Wäsche eingebracht werden und vorteilhaft mit sich in dem Laugenbehälter befindender Waschflüssigkeit wie beispielsweise Wasser verdünnt und so eine Anwendungslösung erzeugt werden, die in die Wäsche eingebracht wird. Die Anbindung der Dosierstelle an die Umflutpumpe hat den weiteren Vorteil, dass die Dosierstelle an ein nicht schwingendes Bauteil angebunden ist und eine feste diffusionsdichte Verrohrung möglich ist.On the other hand, the concentrated mixture obtained can be introduced into the laundry by operating the circulating pump at a speed equal to or above the delivery speed and advantageously diluted with washing liquid in the tub, such as water, to generate an application solution that is introduced into the laundry. The connection of the metering point to the circulation pump has the further advantage that the metering point is connected to a non-vibrating component and fixed, diffusion-tight piping is possible.

Vorzugsweise weist die Waschmaschine einen Wasserzulauf auf, der ausgelegt ist, bei Aktivierung Wasser in den Laugenbehälter einzuspeisen. Die Umfluteinrichtung ist von dem Wasserzulauf der Waschmaschine nicht direkt abhängig und mit diesem nicht direkt verbunden sondern nur indirekt über den Laugenbehälter verbunden, so dass eine Einspeisung der Waschmittel-Komponenten ohne Starten des Wasserzulaufs möglich ist.The washing machine preferably has a water inlet which is designed to feed water into the tub when activated. The flooding device is not directly dependent on the water supply to the washing machine and is not directly connected to it, but only indirectly via the tub, so that the detergent components can be fed in without starting the water supply.

Vorzugsweise wird zeitlich vor dem Einspeisen der Waschmittel-Komponenten der Wasserzulauf aktiviert, sodass Waschflüssigkeit in Form von Wasser in den Laugenbehälter gefüllt wird. Dadurch wird sich in der Trommel befindliche Wäsche durchfeuchtet. Diese Ausführungsform ermöglicht das Mischen von konzentrierten Waschmittel-Komponenten zur Erhöhung der Ausbeute von Aktivsubstanzen wie z.B. Bleichmittel und anschließendem Verdünnen zur Erzeugung einer Anwendungslösung bzw. Waschflotte und Einbringen der Anwendungslösung in die Wäsche, da bei Betreiben der Umflutpumpe bei einer Drehzahl gleich oder größer der Förderdrehzahl die sich in dem Laugenbehälter befindende Waschflüssigkeit mit dem bei Betreiben der Umflutpumpe bei einer Drehzahl unterhalb der Förderdrehzahl erzeugten Waschmittel-Komponenten-Gemisch gemischt wird. Durch das Verdünnen kann verhindert werden, dass die Wäsche einer hohen WaschmittelKonzentration ausgesetzt wird.The water inlet is preferably activated before the detergent components are fed in, so that washing liquid is filled into the tub in the form of water. This means that laundry in the drum is soaked through. This embodiment enables the mixing of concentrated detergent components to increase the yield of active substances such as e.g. Bleach and subsequent dilution to generate an application solution or wash liquor and introduction of the application solution into the laundry, since when the circulating pump is operated at a speed equal to or greater than the delivery speed, the washing liquid in the tub is compared with that when the circulating pump is operated at a speed below the Delivery speed generated detergent component mixture is mixed. Thinning can prevent the laundry from being exposed to a high concentration of detergent.

In einer bevorzugten Ausführungsform wird vor dem Einspeisen der mindestens zwei Waschmittel-Komponenten in die Umflutpumpe sich in dem Laugenbehälter befindende Waschflüssigkeit in Form von Wasser durch die Umfluteinrichtung aus dem ersten Bereich des Laugenbehälters in den zweiten Bereich des Laugenbehälters gefördert. Das Fördern wird vorzugsweise beendet, wenn mit dem Einspeisen der mindestens zwei Waschmittel-Komponenten in die Umflutpumpe begonnen wird. Dadurch kann erreicht werden, dass die Umflutpumpe möglichst wenig Waschflüssigkeit in Form von Wasser während des Einspeisens der Waschmittel-Komponenten enthält. So können einerseits konzentrierte Waschmittel-Komponenten gemischt werden. Andererseits kann das erhaltene konzentrierte Waschmittel-Komponenten-Gemisch durch Betreiben der Umflutpumpe bei einer Drehzahl gleich oder oberhalb der Förderdrehzahl anschließend verdünnt und so eine Anwendungslösung erzeugt werden, die in die Wäsche eingebracht wird.In a preferred embodiment, before the at least two detergent components are fed into the circulation pump, washing liquid located in the tub is conveyed in the form of water through the circulation device from the first area of the tub to the second area of the tub. The pumping is preferably ended when the at least two detergent components are started to be fed into the circulation pump. It can thereby be achieved that the circulation pump contains as little washing liquid as possible in the form of water while the washing agent components are being fed in. On the one hand, concentrated detergent components can be mixed. On the other hand, the concentrated detergent-component mixture obtained can then be diluted by operating the circulating pump at a speed equal to or above the delivery speed and thus an application solution can be generated which is introduced into the laundry.

In einer bevorzugten Ausführungsform werden die Waschmittel-Komponenten in einen Saugbereich der Umflutpumpe eingespeist. Die Umflutpumpe ist in dieser Ausgestaltung des Verfahrens aktiviert und wird bei einer Drehzahl unterhalb der Förderdrehzahl betrieben. Nach Mischung der Waschmittel-Komponenten in der Umflutpumpe wird die Umflutpumpe bei einer Drehzahl gleich oder oberhalb der Förderdrehzahl betrieben und fördert das Waschmittel-Komponenten-Gemisch in den zweiten Bereich des Laugenbehälters. Das Waschmittel-Komponenten-Gemisch wird vorzugsweise direkt auf die Wäsche gesprüht, so dass ein kurzer Weg bis zur Wirkstelle des Waschmittel-Komponenten-Gemischs möglich ist.In a preferred embodiment, the detergent components are fed into a suction area of the circulation pump. The circulation pump is activated in this embodiment of the method and is operated at a speed below the delivery speed. After the detergent components have been mixed in the circulation pump, the circulation pump is operated at a speed equal to or above the delivery speed and conveys the detergent-component mixture into the second area of the tub. The The detergent-component mixture is preferably sprayed directly onto the laundry so that a short path to the point of action of the detergent-component mixture is possible.

Vorzugsweise wird die Umflutpumpe bei einer Drehzahl unterhalb der Förderdrehzahl für eine vorbestimmte Misch-Zeit betrieben. Die vorbestimmte Misch-Zeit ist vorzugsweise derart gewählt, dass sie eine vollständige Mischung der Waschmittel-Komponenten erlaubt. Vorzugsweise wird anschließend die Umflutpumpe bei einer Drehzahl gleich oder oberhalb der Förderdrehzahl für eine vorbestimmte Umflut-Zeit betrieben
Vorzugsweise wird zwischen dem Betreiben der Umflutpumpe bei einer Drehzahl unterhalb einer Förderdrehzahl und anschließend bei einer Drehzahl gleich zu oder oberhalb der Förderdrehzahl die in dem Laugenbehälter drehbar gelagerte Trommel zur Aufnahme von Wäsche bei einer Drehzahl zum Schleudern der Wäsche gedreht. Durch das Schleudern der Wäsche kann das durch Mischen in der Umflutpumpe erhaltene Waschmittel-Komponenten-Gemisch weiterhin mit zusätzlicher Waschflüssigkeit verdünnt werden.The circulating pump is preferably operated at a speed below the delivery speed for a predetermined mixing time. The predetermined mixing time is preferably selected such that it allows complete mixing of the detergent components. The circulation pump is then preferably operated at a speed equal to or above the delivery speed for a predetermined circulation time
Preferably, between the operation of the circulation pump at a speed below a delivery speed and then at a speed equal to or above the delivery speed, the drum rotatably mounted in the tub for receiving laundry is rotated at a speed for spinning the laundry. By spinning the laundry, the detergent-component mixture obtained by mixing in the circulation pump can be further diluted with additional washing liquid.

Vorzugsweise sind die mindestens zwei Waschmittel-Komponenten derart ausgewählt, dass sie bei Zusammentreffen eine Aktivsubstanz bevorzugter ein Bleichmittel erzeugen. Auf diese Weise kann die Aktivsubstanz bzw. das Bleichmittel in situ erzeugt werden. Dies ist insbesondere im Fall eines Bleichmittels vorteilhaft, da in Flüssigkeiten vorliegende Bleichmittel oftmals wenig lagerstabil sind. Neben dem Erzielen einer hervorragenden Bleichwirkung an der Wäsche ist eine einfache und sichere Handhabung eines Waschmittels mit Bleichmittelwirkung ohne Gefährdung des Nutzers gegeben, da das Bleichmittel in situ in der Waschmaschine erzeugt wird. Vorzugsweise sind werden daher mindestens zwei vorzugsweise zwei oder bevorzugter drei Waschmittel-Komponenten eingesetzt, die geeignet sind, durch Reaktion ein Bleichmittel zu bilden.The at least two detergent components are preferably selected in such a way that when an active substance comes together they produce a bleaching agent. In this way, the active substance or the bleach can be generated in situ. This is particularly advantageous in the case of a bleaching agent, since bleaching agents present in liquids are often not very stable in storage. In addition to achieving an excellent bleaching effect on the laundry, a detergent with a bleaching effect can be handled easily and safely without endangering the user, since the bleaching agent is generated in situ in the washing machine. It is therefore preferable to use at least two, preferably two or more preferably three, detergent components which are suitable for reacting to form a bleaching agent.

Vorzugsweise werden die mehreren Waschmittel-Komponenten gleichzeitig in die Umfutpumpe eingespeist. Alternativ oder zusätzlich bevorzugt werden die Waschmittel-Komponenten zeitversetzt in die Umflutpumpe eingespeist. Beispielsweise ist es möglich, dass eine Waschmittel-Komponente in der Umflutpumpe vorgelegt wird und eine oder mehrere weitere Waschmittel-Komponente/n zu ihr zudosiert wird/werden. Vorzugsweise wird die Umflutpumpe während des Einspeisens einer weiteren Waschmittel-Komponente bei der Drehzahl unterhalb der Förderdrehzahl betrieben.The multiple detergent components are preferably fed into the circulation pump at the same time. Alternatively or in addition, the detergent components are preferably fed into the circulation pump with a time delay. For example, it is possible for a detergent component to be placed in the circulation pump and one or more further detergent components to be added to it. The circulation pump is preferably operated at the speed below the delivery speed while a further detergent component is being fed in.

Es ist auch möglich, dass die Schritte Einspeisen der Waschmittel-Komponenten, Betreiben, der Umflutpumpe bei und/oder nach dem Einspeisen der mindestens zwei Waschmittel-Komponenten bei einer Drehzahl unterhalb einer Förderdrehzahl, optional Schleudern der Wäsche, anschließend Betreiben der Umflutpumpe bei einer Drehzahl gleich zu oder oberhalb der Förderdrehzahl ein- oder mehrmals wiederholt werden, so dass die Waschmittel-Komponenten der Umflutpumpe bzw. ihr Gemisch dem Laugenbehälter portionsweise zugeführt werden.It is also possible that the steps of feeding in the detergent components, operating the circulating pump during and / or after feeding in the at least two detergent components at a speed below a delivery speed, optionally spinning the laundry, then operating the circulating pump at one speed be repeated one or more times equal to or above the conveyor speed, so that the Detergent components of the circulation pump or their mixture are fed to the tub in portions.

Die Erfindung betrifft ferner eine Waschmaschine mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit, einer in dem Laugenbehälter drehbar gelagerten Trommel zur Aufnahme von Wäsche, einer Umfluteinrichtung zum Fördern der Waschflüssigkeit von einem ersten Bereich des Laugenbehälters in einen zweiten Bereich des Laugenbehälters und einer Steuer- oder Regeleinrichtung zum Steuern oder Regeln einzelner Phasen von Waschprogrammen, wobei die Umfluteinrichtung eine Umflutpumpe aufweist, die ein Verbindungselement zur Verbindung mit dem ersten Bereich des Laugenbehälters und einen Umflut-Druckstutzen zur Verbindung mit dem zweiten Bereich des Laugenbehälters und einen oder mehrere Umflut-Ansaugstutzen zur Verbindung mit einer oder mehreren Dosiereinrichtungen für Waschmittel-Komponenten aufweist und wobei die Umflutpumpe bei einer Drehzahl zum Bewirken eines Mischvorganges unterhalb einer Förderdrehzahl, bei der die Waschflüssigkeit aus dem ersten Bereich des Laugenbehälters in den zweiten Bereich des Laugenbehälters förderbar ist, und bei einer weiteren Drehzahl zum Erwirken eines Umflutvorganges gleich zu oder oberhalb der Förderdrehzahl betreibbar ist.The invention also relates to a washing machine with a tub for holding washing liquid, a drum rotatably mounted in the tub for holding laundry, a flooding device for conveying the washing liquid from a first area of the tub to a second region of the tub and a control or regulating device for controlling or regulating individual phases of washing programs, the flooding device having a flooding pump which has a connecting element for connection to the first area of the tub and a flooding pressure port for connecting to the second area of the tub and one or more flooding suction ports for connection with having one or more metering devices for detergent components and wherein the circulating pump at a speed for effecting a mixing process below a delivery speed at which the washing liquid from the first area of the tub in the two iten area of the tub can be conveyed, and can be operated at a further speed to effect a flooding process equal to or above the conveying speed.

Vorzugsweise steuert oder regelt die Steuer- oder Regeleinrichtung eine Aktivität der Umflutpumpe. Vorzugsweise ist die Steuer- oder Regeleinrichtung ausgelegt, bei Aktivierung der Umflutpumpe ihre Drehzahl zu steuern oder zu regeln, so dass die Drehzahl bedarfsabhängig unterhalb der Förderdrehzahl oder gleich bzw. höher als die Förderdrehzahl ist. D.h., die Steuer- oder Regeleinrichtung ist vorzugsweise ausgelegt, die Umflutpumpe derart zu steuern oder zu regeln, dass sie je nach Bedarf als Mischkammer oder Fördereinrichtung zum Fördern von Waschflüssigkeit aus dem ersten Bereich des Laugenbehälters in den zweiten Bereich des Laugenbehälters fungieren kann. Vorzugsweise ist die Steuer- oder Regeleinrichtung eingerichtet, ein Betreiben der Umflutpumpe in einem Verfahren gemäß einer oder mehrerer der vorstehend beschriebenen Ausführungsformen zu steuern oder zu regeln.The control or regulating device preferably controls or regulates an activity of the circulation pump. The control or regulating device is preferably designed to control or regulate its speed when the circulating pump is activated, so that the speed is below the delivery speed or equal to or higher than the delivery speed, depending on requirements. That is, the control or regulating device is preferably designed to control or regulate the circulation pump in such a way that it can function as a mixing chamber or conveying device for conveying washing liquid from the first area of the tub to the second area of the tub, as required. The control or regulating device is preferably set up to control or regulate an operation of the circulation pump in a method in accordance with one or more of the embodiments described above.

In einer bevorzugten Ausführungsform weist die Umflutpumpe zwei, drei oder vier Umflut-Ansaugstutzen zur Verbindung mit der oder den Dosiereinrichtungen für die Waschmittel-Komponenten auf. Dadurch ist die Waschmaschine ausgelegt, so dass zwei, drei oder vier Waschmittel-Komponenten in die Umflutpumpe gleichzeitig und/oder nacheinander eingespeist werden können.In a preferred embodiment, the circulation pump has two, three or four circulation suction nozzles for connection to the metering device or devices for the detergent components. As a result, the washing machine is designed so that two, three or four detergent components can be fed into the circulation pump simultaneously and / or one after the other.

Die Umfluteinrichtung weist weiterhin ein Umflutrohr, das die Umflutpumpe über ihr Verbindungselement mit dem ersten Bereich des Laugenbehälter verbindet, und eine Umflutleitung auf, die mit der Umflutpumpe über ihren Umflut-Druckstutzen verbunden ist und ausgelegt ist, die Umfluteinrichtung verlassende Waschflüssigkeit in den zweiten Bereich des Laugenbehälters einzubringen. Die Umflutleitung weist vorzugsweise zur besseren Verteilung der Waschflüssigkeit in dem zweiten Bereich des Laugenbehälters vorzugsweise eine Umflut-Düse auf, durch die die Waschflüssigkeit in den Laugenbehälter gesprüht wird.The flooding device also has a flooding pipe which connects the flooding pump to the first area of the tub via its connecting element, and a flooding line which is connected to the flooding pump via its flooding pressure connection and is designed to transfer washing liquid leaving the flooding device into the second area of the Bring the tub. The bypass line preferably points for better distribution of the washing liquid in the second area of the tub preferably has a flood nozzle through which the washing liquid is sprayed into the tub.

Der erste Bereich des Laugenbehälters ist vorzugsweise der untere Bereich des Laugenbehälters, und der zweite Bereich des Laugenbehälters ist vorzugsweise der obere Bereich des Laugenbehälters, bezogen auf die betriebsgemäße Aufstellposition der Waschmaschine. Das Waschmittel-Komponenten-Gemisch wird daher vorzugsweise von oben auf die sich in der Trommel befindenden Wäsche aufgebracht.The first area of the tub is preferably the lower region of the tub, and the second region of the tub is preferably the upper region of the tub, based on the operational position of the washing machine. The detergent-component mixture is therefore preferably applied from above to the laundry in the drum.

Jede Dosiereinrichtung weist vorzugsweise eine automatische Dosiereinheit auf. Die Dosiereinrichtung ist mit der Waschmaschine über mindestens eine Dosierleitung verbunden. Jede Waschmittel-Komponente wird durch die mindestens eine Dosierleitung aus der Dosiereinheit in die Umfluteinrichtung in einer vorbestimmten Dosierung eingespeist. Die Dosierung kann an der Dosiereinrichtung manuell eingestellt werden oder durch Auswählen eines Waschprogramms an der Waschmaschine gesteuert werden. Vorzugsweise ist die Dosiereinrichtung zu der Waschmaschine getrennt ausgebildet. Mindestens eine Dosierleitung ist an die Dosiereinrichtung und jeweils an den mindestens einen Umflut-Ansaugstutzen montiert. Dadurch kann die Zufuhr der Waschmittel-Komponenten direkt vor die Umflutpumpe in ihren Saugbereich erfolgen. Die Dosierleitung verbindet die Dosiereinrichtung direkt mit der Umfluteinrichtung. Die Dosiereinrichtung kann mehrere Kammern zur Aufnahme jeweils einer Waschmittel-Komponente aufweisen. Alternativ oder zusätzlich kann für jede Waschmittel-Komponente eine separate Dosiereinrichtung vorgesehen sein.Each metering device preferably has an automatic metering unit. The metering device is connected to the washing machine via at least one metering line. Each detergent component is fed through the at least one metering line from the metering unit into the flooding device in a predetermined dosage. The dosage can be set manually on the dosing device or controlled by selecting a washing program on the washing machine. The metering device is preferably designed separately from the washing machine. At least one metering line is mounted on the metering device and in each case on the at least one bypass suction nozzle. As a result, the detergent components can be fed into its suction area directly in front of the circulation pump. The dosing line connects the dosing device directly with the flooding device. The metering device can have several chambers for receiving one detergent component each. Alternatively or additionally, a separate metering device can be provided for each detergent component.

Bei der Waschmaschine kann es sich um ein Haushaltsgerät oder ein gewerblich genutztes Gerät handeln. Unter den Begriff "Waschmaschine" fallen auch Kombigeräte wie beispielsweise ein Waschtrockner.The washing machine can be a household appliance or a commercially used appliance. The term "washing machine" also includes combination devices such as a washer-dryer.

Bei den Waschmittel-Komponenten handelt es sich vorzugsweise um flüssige Komponenten. Eine Waschmittel-Komponente kann ein oder mehrere Bestandteile aufweisen. Ein Bestandteil kann dabei zu anderen Bestandteilen einer weiteren Waschmittel-Komponente inert oder reaktiv sein.The detergent components are preferably liquid components. A detergent component can have one or more ingredients. One constituent can be inert or reactive to other constituents of a further detergent component.
