Description

Die Erfindung betrifft eine Waschmaschine oder einen Waschtrockner mit Einrichtungen für die programmgemäße Zugabe von flüssigen und/oder pulverförmigen Wäschebehandlungsmitteln in den Laugenbehälter, einer Bedienblende, einem im Blendenbereich der Maschine angeordneten Waschmitteleinspülkasten und mit einem an anderer Stelle der Maschine angeordneten Vorratsbehälter für flüssige Wäschebehandlungsmittel.The invention relates to a washing machine or a washer-dryer with devices for the program-based addition of liquid and / or powdered laundry treatment agents into the tub, an operating panel, a detergent dispenser box arranged in the panel area of the machine and with a storage container for liquid laundry treatment agents arranged elsewhere on the machine.

Die vorgegebene Dosiereinrichtung soll die automatische Zugabe von flüssigen Wäschebehandlungsmitteln während des Waschgangs ermöglichen.The specified metering device is intended to enable the automatic addition of liquid laundry treatment agents during the washing cycle.

Es ist bereits bekannt, zur Erfüllung dieser Erfordernisse eine Wäschebehandlungsmaschine mit einem Vorratsbehälter und einer Dosierpumpe für die Zugabe von Wäschebehandlungsmitteln auszurüsten.To meet these requirements, it is already known to equip a laundry treatment machine with a storage container and a metering pump for the addition of laundry treatment agents.

Aus der DE-U 70 22 325 ist beispielsweise eine Dosiereinrichtung für Weichspülmittel bekannt, wodurch die für den Spülgang benötigte Menge Weichspülmittel automatisch in den Laugenbehälter oder in die Waschmitteleinspülkammer dosiert wird.
Weiterhin ist aus der DE-OS 34 47 303 eine Waschmaschine bekannt, bei der ein Vorratsbehälter für Flüssigmittel über einen Einfüllstutzen im Einspülkasten befüllt werden kann. Das Flüssigmittel wird aus dem Vorratsbehälter direkt in den Laugenbehälter gepumpt.From DE-U 70 22 325, for example, a dosing device for fabric softener is known, whereby the amount of fabric softener required for the rinse cycle is automatically dosed into the tub or into the detergent dispensing chamber.
Furthermore, a washing machine is known from DE-OS 34 47 303, in which a reservoir for liquid medium can be filled via a filler neck in the dispenser case. The liquid medium is pumped directly from the storage container into the tub.

Bei den bekannten Dosiereinrichtungen ist der Vorratsbehälter jeweils nur für eine Art von Wäschebehandlungsmitteln vorgesehen - z. B. nur für Weichspülmittel oder Flüssigwaschmittel. Der Benutzer des Gerätes kann nicht individuell festlegen, welche Wäschebehandlungsmittel er dem Waschprozeß automatisch zuführen will.In the known metering devices, the storage container is only provided for one type of laundry treatment agent - e.g. B. only for fabric softener or liquid detergent. The user of the device cannot individually determine which laundry treatment agents he wants to feed the washing process automatically.

Aufgabe der Erfindung ist es daher, eine Waschmaschine oder einen Waschtrockner mit einer Einrichtung für die Zugabe flüssiger Wäschebehandlungsmittel so zu gestalten, daß der Benutzer je nach Bedarf unterschiedliche Wäschebehandlungsmittel in dem Vorratsbehälter bevorraten kann und daß die jeweils erforderliche Dosiermenge des eingefüllten Mittels automatisch an der richtigen Stelle des Waschprogrammablaufs direkt in den Laugenbehälter dosiert wird.The object of the invention is therefore to design a washing machine or a washer-dryer with a device for adding liquid laundry treatment agents in such a way that the user can store different laundry treatment agents in the storage container as required and that the respectively required dosage amount of the agent added is automatically correct Point of the washing program is dosed directly into the tub.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Ansprüchen.This object is achieved by the features of claim 1. Advantageous refinements and developments of the invention result from the following claims.

Die mit der Erfindung erzielbaren Vorteile liegen insbesondere darin, daß aus einem Vorratsbehälter je nach Bedarf bzw. Waschgewohnheiten der Benutzer wahlweise flüssige Wäschebehandlungsmittel wie Flüssigwaschmittel, Enthärtungsmittel und flüssige Chlorbleiche in den Vor- und/oder Hauptwaschgang oder Weichspülmittel in den letzten Spülgang dosiert werden können.
Bei Zugabe von Flüssigwaschmittel wird die entsprechende Waschmittelmenge im Zwei-Laugenprogramm automatisch fachgerecht in 1/4 für die Vorwäsche und 3/4 für die Hauptwäsche aufgeteilt und dem Laugenbehälter zugeführt. Durch die Betätigung einer Verstelleinrichtung im Bereich des Vorratsbehälters legt der Benutzer fest, welches Wäschebehandlungsmittel in dem Vorratsbehälter bevorratet wird und gibt dadurch der Programmsteuerung ein Signal, wann die programmgemäße Zugabe des Behandlungsmittels erfolgen muß.
Die Dosiermenge kann vom Benutzer vorgewählt werden und wird für die folgenden Waschgänge gespeichert, damit nicht vor jedem weiteren Waschgang mit gleichem Wäschebehandlungsmittel eine erneute Festlegung der Dosiermenge erfolgen muß.
In einer vorteilhaften Weiterbildung der Erfindung ist eine Dosierautomatik vorgesehen, die den Wert der Dosiermenge in Abhängigkeit der zu Beginn des ersten Waschganges zugelaufenen Wassermenge berechnet. Dadurch ist eine Dosiermengenanpassung für unterschiedliche Gewebearten und Wäschemengen möglich.The advantages that can be achieved with the invention are in particular that, depending on the needs or washing habits of the user, liquid laundry treatment agents such as liquid detergents, softening agents and liquid chlorine bleach can be metered into the pre-wash and / or main wash cycle or fabric softener into the last rinse cycle.
When adding liquid detergent, the corresponding amount of detergent in the two-lye program is automatically professionally divided into 1/4 for the prewash and 3/4 for the main wash and fed to the tub. By actuating an adjusting device in the area of the storage container, the user determines which laundry treatment agent is stored in the storage container and thereby gives the program control a signal when the treatment agent must be added according to the program.
The dosing amount can be preselected by the user and is saved for the following wash cycles, so that the dosing amount does not have to be determined again before each further wash cycle with the same laundry treatment agent.
In an advantageous development of the invention, an automatic dosing system is provided, which calculates the value of the dosing quantity as a function of the quantity of water that has flowed in at the beginning of the first washing cycle. This makes it possible to adjust the dosage for different types of fabrics and laundry.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Wäschebehandlungsmaschine mit schematisch dargestelltem Vorratsbehälter (3),
  • Fig. 2 eine schematische Darstellung der Wäschebehandlungsmaschine
  • Fig. 3 die Anzeigeeinrichtung (11) der Bedienblende (1),
  • Fig. 4 den Vorratsbehälter (3) mit Füllstutzen (21) in der Seitenansicht im Schnitt.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • 1 is a laundry treatment machine with a schematically illustrated storage container (3),
  • Fig. 2 is a schematic representation of the laundry treatment machine
  • 3 the display device (11) of the control panel (1),
  • Fig. 4 shows the storage container (3) with filler neck (21) in a side view in section.

In der Fig. 1 ist die Bedienblende einer Wäschebehandlungsmaschine mit 1 bezeichnet.
Im Bereich der Bedienblende (1) ist ein Waschmitteleinspülkasten (2) für die manuelle Zugabe von Wäschebehandlungsmitteln vorgesehen. Der Vorratsbehälter (3) für flüssige Wäschebehandlungsmittel ist im unteren Bereich der Maschine hinter einer Montageklappe herausnehmbar angeordnet. Der Vorratsbehälter (3) kann z. B. in Führungsnuten (4) in das Gehäuse einschiebbar gelagert sein. Im Bereich des Vorratsbehälters (3) ist eine Verstelleinrichtung (5) vorgesehen, an der der Benutzer vorgeben muß, welche Art von Wäschebehandlungsmittel in den Vorratsbehälter (3) eingefüllt wurde. Die Verstelleinrichtung (5) kann z. B. als Einschubsperre für den Vorratsbehälter (3) ausgebildet sein. Der Vorratsbehälter (3) weist dabei vorzugsweise zur Einschubrichtung des Behälters schräg verlaufende Führungsnuten (6, 7) auf, in denen der als Einschubsperre ausgebildete Verstellhebel der Verstelleinrichtung (5) geführt wird. Soll der Vorratsbehälter (3) in das Gehäuse der Maschine eingeschoben werden, muß zunächst der Verstellhebel in die Richtung einer Führungsnut (6 oder 7) gelegt werden, damit der Vorratsbehälter (3) in das Gehäuse eingeschoben werden kann. Die Führungsnuten (6, 7) sind mit Symbolen (8, 9) für verschiedene Wäschebehandlungsmittel versehen. Je nachdem, welche Art von Wäschebehandlungsmittel in den Vorratsbehälter (3) gefüllt wurde, muß der Verstellhebel in die entsprechende Winkelstellung zur Einschubrichtung gebracht werden. Die Verstelleinrichtung (5) ist schaltungstechnisch mit der Programmsteuereinrichtung (10) der Maschine verbunden. Je nach Winkelstellung des Verstellhebels erfolgt die automatische programmgemäße Zugabe des flüssigen Wäschebehandlungsmittels. Wurde z. B. Weichspülmittel in den Vorratsbehälter (3) eingefüllt, muß der Verstellhebel der Verstelleinrichtung (5) in die Richtung der Position des Symbols (9) zeigen. Entsprechend der Winkelstellung des Verstellhebels erfolgt die automatische Dosierung des Weichspülmittels im letzten Spülgang. Wenn Flüssigwaschmittel in den Vorratsbehälter (3) eingefüllt wurde, muß der Benutzer den Verstellhebel in Richtung der Position des Symbols (8) umlegen, damit der Programmsteuereinrichtung (10) signalisiert wird, daß die Zugabe des Mittels in den Vor- bzw. Hauptwaschgang erfolgen muß. Dabei wird die Dosiermenge automatisch fachgerecht in 1/4 für den Vorwaschgang und 3/4 für den Hauptwaschgang aufgeteilt. Wenn ein Waschprogramm ohne Vorwäsche angewählt wurde, erfolgt die Zugabe der gesamten Dosiermenge allein in den Hauptwaschgang. Im Bereich des Vorratsbehälters (3) können noch zusätzliche Einstellungen für weitere Wäschebehandlungsmittel vorgesehen werden.
Durch die als Einschubsperre ausgebildete Verstelleinrichtung (5) wird der Benutzer nach dem Befüllen des Vorratsbehälters (3) gezwungen, der Programmsteuerung (10) zu signalisieren, welche Art von Wäschebehandlungsmittel in den Behälter gefüllt wurde. Eine Fehldosierung aufgrund einer falschen Mittelangabe des Benutzers bei der Programmwahl ist somit ausgeschlossen.
Innerhalb der Anzeigeeinrichtung (11) der Bedienblende (1) der Maschine wird über die Mittelanzeige (12, 13) angezeigt, welches Wäschebehandlungsmittel in den Behälter gefüllt wurde. Für die Anzeige der Art des Wäschebehandlungsmittels kann z. B. jedem Symbol der Anzeigeeinrichtung (11) eine LED zugeordnet sein, die bei Anwahl der Einrichtung für die automatische Zugabe der flüssigen Wäschebehandlungsmittel über die Schalteinrichtung (14) als Dauerlicht aufleuchtet.
Entsprechend der Anzahl der Einstellmöglichkeiten im Bereich des Vorratsbehälters (3) für unterschiedliche Wäschebehandlungsmittel sind in der Anzeigeeinrichtung (11) Symbole und LEDs für die Mittelanzeige (12, 13) vorhanden. Für den Vorratsbehälter (3) ist eine Flüssigkeitsniveaumeßeinrichtung (15) vorgesehen. Der Wert des Flüssigkeitsstandes kann über die Anzeigeeinrichtung (11) der Bedienblende (1) angezeigt werden. Es wäre aber auch möglich, ein Restniveau oder einen leeren Vorratsbehälter (3) durch Blinken einer LED zu signalisieren.
Die Anwahl der Einrichtung für die automatische Zugabe der flüssigen Wäschebehandlungsmittel kann über eine Schalteinrichtung (14) erfolgen. Die Mittelanzeige (12, 13) leuchtet dann als Dauerlicht auf.
Weiterhin kann die entsprechende Dosiermenge innerhalb der Anzeigeeinrichtung (11) angezeigt werden. Hierzu ist es möglich, verschiedenen Zahlenwerten für die Dosiermengen LEDs zuzuordnen, die entsprechend der eingestellten Dosiermenge aufleuchten oder den genauen Zahlenwert in einem Display anzeigen zu lassen. Wird während der Entnahme des Wäschebehandlungsmittels ein Restniveau erreicht, blinkt die Mittelanzeige (12 oder 13) oder eine Restniveauanzeige (16), um den Benutzer auf das erforderliche Nachfüllen des Vorratsbehälters (3) aufmerksam zu machen. Die Vorwahl der Dosiermenge erfolgt über Eingabetasten (17) innerhalb der Anzeigeeinrichtung (11). Mit der Taste "+" und der Taste "-" wird das Volumen nach Herstellerangabe für das Wäschebehandlungsmittel angewählt und in einem Memory-Speicher der Programmsteuereinrichtung (10) für die nachfolgenden Waschgänge festgehalten. Eine Veränderung des abgespeicherten Wertes kann ebenfalls über die Eingabetasten (17) erfolgen. Wenn ein Waschgang mit automatischer Dosierung angewählt wurde, leuchten die LEDs der Mittel- und Mengenanzeige (12 oder 13 und 18) mit dem Start des Programms als Dauerlicht auf. Dabei wird die abgespeicherte Dosiermenge und die Art des in dem Vorratsbehälter (3) bevorrateten Wäschebehandlungsmittels angezeigt. Für eine Umstellung auf ein anderes Wäschebehandlungsmittel - z. B. von Weichspülmittel auf Flüssigwaschmittel - ist die Reinigung des Vorratsbehälters (3) erforderlich und ein Reinigungsprogrammschritt für die Zufuhrleitung (19) der Dosiereinrichtung vorgesehen. Dazu muß die Zufuhrleitung (19) für das Wäschebehandlungsmittel vom Vorratsbehälter (3) gelöst werden. Der Vorratsbehälter (3) sollte gereinigt und mit Wasser gefüllt wieder mit der Zufuhrleitung (19) verbunden und in das Gehäuse eingeschoben werden. Die Zufuhrleitung (19) für das Wäschebehandlungsmittel ist vom Vorratsbehälter (3) bis zum Einspülpunkt (20) in den Laugenbehälter noch mit dem vorhergehenden Wäschebehandlungsmittel gefüllt. Diese Restmenge kann durch ein Durchspülen mit dem Wasser aus dem Vorratsbehälter (3) entfernt werden. Das Durchspülen der Zufuhrleitung (19) wird durch ein gleichzeitiges Drücken der Tasten "+" und "-" (17) eingeleitet. Dabei wird Wasser entsprechend der angezeigten Dosiermenge durch die Zufuhrleitung (19) gepumpt. Zweckmäßigerweise kann vor dem Durchspülen die maximale Dosiermenge angwählt werden. Nach dem Durchspülen der Zufuhrleitung (19) kann das Wasser aus dem Vorratsbehälter (3) entfernt und das neue Wäschebehandlungsmittel eingefüllt werden.In Fig. 1, the control panel of a laundry treatment machine is designated 1.
A detergent dispenser drawer (2) is provided in the area of the control panel (1) for the manual addition of laundry treatment agents. The storage container (3) for Liquid laundry treatment agent is removably arranged in the lower area of the machine behind an assembly flap. The reservoir (3) can, for. B. in guide grooves (4) can be inserted in the housing. An adjustment device (5) is provided in the area of the storage container (3), on which the user must specify which type of laundry treatment agent has been filled into the storage container (3). The adjusting device (5) can, for. B. be designed as a slide-in lock for the reservoir (3). The storage container (3) preferably has guide grooves (6, 7) which run obliquely with respect to the insertion direction of the container and in which the adjustment lever of the adjustment device (5), which is designed as an insertion lock, is guided. If the storage container (3) is to be inserted into the housing of the machine, the adjusting lever must first be placed in the direction of a guide groove (6 or 7) so that the storage container (3) can be inserted into the housing. The guide grooves (6, 7) are provided with symbols (8, 9) for different laundry treatment agents. Depending on the type of laundry treatment agent that has been filled into the storage container (3), the adjusting lever must be brought into the corresponding angular position to the direction of insertion. In terms of circuitry, the adjustment device (5) is connected to the program control device (10) of the machine. Depending on the angular position of the adjustment lever, the liquid laundry treatment agent is automatically added according to the program. Has z. B. Filled with fabric softener in the storage container (3), the adjusting lever of the adjusting device (5) must point in the direction of the position of the symbol (9). Depending on the angular position of the adjustment lever, the softener is dosed automatically in the last rinse. If liquid detergent has been poured into the storage container (3), the user flips the adjusting lever in the direction of the position of the symbol (8) so that the program control device (10) is signaled that the agent must be added to the pre-wash or main wash cycle. The dosing quantity is automatically divided professionally into 1/4 for the pre-wash and 3/4 for the main wash. If a wash program without prewash has been selected, the entire dosage is added to the main wash cycle alone. Additional settings for further laundry treatment agents can be provided in the area of the storage container (3).
The adjustment device (5), designed as a slide-in lock, forces the user, after filling the storage container (3), to signal to the program controller (10) which type of laundry treatment agent has been filled into the container. Incorrect dosing due to incorrect user information when selecting a program is therefore excluded.
Within the display device (11) of the control panel (1) of the machine, the center display (12, 13) shows which laundry treatment agent has been filled into the container. For the display of the type of laundry treatment agent, for. B. each symbol of the display device (11) can be assigned an LED which lights up as a continuous light when the device for the automatic addition of the liquid laundry treatment agent is selected via the switching device (14).
Depending on the number of setting options in the area of the storage container (3) for different laundry treatment agents, symbols and LEDs for the central display (12, 13) are present in the display device (11). A liquid level measuring device (15) is provided for the storage container (3). The value of the liquid level can be displayed on the display (11) of the control panel (1). However, it would also be possible to signal a residual level or an empty storage container (3) by blinking an LED.
The device for the automatic addition of the liquid laundry treatment agent can be selected via a switching device (14). The center display (12, 13) then lights up as a steady light.
The corresponding metered quantity can also be displayed within the display device (11). For this purpose, it is possible to assign different numerical values for the dosing quantities to LEDs that light up according to the set dosing quantity or to have the exact numerical value shown on a display. If a residual level is reached during the removal of the laundry treatment agent, the middle display (12 or 13) or a residual level display (16) flashes to draw the user's attention to the need to refill the storage container (3). The preselection of the dosing quantity takes place via input keys (17) within the display device (11). With the "+" key and the "-" key, the volume is selected for the laundry treatment agent according to the manufacturer's instructions and stored in a memory of the program control device (10) for the subsequent wash cycles. The stored value can also be changed using the input keys (17). If a wash cycle with automatic dosing has been selected, the LEDs of the medium and quantity display (12 or 13 and 18) light up continuously when the program starts. The stored dosage and the type of laundry treatment agent stored in the storage container (3) are displayed. For a change to another laundry treatment agent - e.g. B. from fabric softener to liquid detergent - the cleaning of the storage container (3) is required and a cleaning program step for the feed line (19) of the metering device is provided. For this purpose, the supply line (19) for the laundry treatment agent from the storage container (3) be solved. The storage container (3) should be cleaned and filled with water, reconnected to the supply line (19) and pushed into the housing. The supply line (19) for the laundry treatment agent is still filled with the previous laundry treatment agent from the storage container (3) to the washing point (20) in the tub. This residual amount can be removed from the storage container (3) by rinsing with the water. Flushing the supply line (19) is initiated by simultaneously pressing the "+" and "-" (17) buttons. Water is pumped through the supply line (19) in accordance with the dosing quantity indicated. The maximum dosing quantity can expediently be selected before rinsing. After flushing the supply line (19), the water can be removed from the storage container (3) and the new laundry treatment agent can be filled in.

Nach dem Wechsel des Wäschebehandlungsmittels ist die Zufuhrleitung (19) vom Vorratsbehälter (3) über die Mittelpumpe (21) bis zum Einspülpunkt (20) in den Laugenbehälter noch nicht mit Wäschebehandlungsmittel gefüllt. Ein Vorfüllen der Zufuhrleitung (19) kann ebenfalls durch gleichzeitiges Drücken der Tasten "+" und "-" (17) erfolgen. Während des Pumpvorganges blinkt die Dosiermengenanzeige (18).After changing the laundry treatment agent, the supply line (19) from the storage container (3) via the central pump (21) to the washing point (20) in the tub is not yet filled with laundry treatment agent. The feed line (19) can also be primed by simultaneously pressing the "+" and "-" (17) buttons. The metering quantity indicator (18) flashes during the pumping process.

Zur leichteren Handhabung beim Befüllen des Vorratsbehälters (3) kann der Behälter mit einem Füllstutzen (22) versehen sein. Der Füllstutzen (22) ist in einem Ansatz (23) des Vorratsbehälters (3) einschiebbar gelagert. In der im Ansatz (23) eingeschobenen Stellung verschließt der Füllstutzen (22) den Vorratsbehälter (3). In der ausgezogenen Stellung bietet er eine große Öffnung zum leichten Befüllen des Vorratsbehälters (3). Durch das Herausziehen des Füllstutzens (22) aus dem Ansatz (23) wird der Füllstutzen (22) automatisch geöffnet und vergrößert.
Damit das Wäschebehandlungsmittel beim Einfüllen in den Vorratsbehälter (3) nicht bis in den Füllstuzten (22) steht, ist eine optische "Voll-Anzeige" (24) am Vorratsbehälter (3) vorhanden.
Um den Behälter nach dem Befüllen wieder in das Gehäuse einschieben zu können, muß der Verstellhebel der Verstelleinrichtung (5) wieder entsprechend der Befüllung in die richtige Winkellage zur Einschubrichtung gebracht werden, damit der Programmsteuereinrichtung (10) signalisiert wird, welche Art von Wäschebehandlungsmittel eingefüllt wurde.
In einer vorteilhaften Weiterbildung der Erfindung wird die programmgemäße Zugabe des Wäschebehandlungsmittels von einer Dosierautomatik innerhalb der Programmsteuerung (10) gesteuert. Die Dosiermenge wird dabei in Abhängigkeit der zu Beginn des ersten Waschganges zugelaufenen Wassermenge berechnet. In einer Wertetabelle sind als Grundlage für die Berechnung der Dosiermenge Nennwassermengen für die unterschiedlichen Waschprogramme und Programmabschnitte abgespeichert. Die zu Beginn des ersten Waschganges zugelaufene Wassermenge wird erfaßt und mit den abgespeicherten Nennwassermengen entsprechend der Programmwahl verglichen. Falls nun z. B. aufgrund einer geringeren Beladungsmenge weniger Wasser zugelaufen ist, verringert sich die über die Anzeigeeinrichtung (11) angezeigte und vorgewählte Dosiermenge im gleichen Verhältnis wie die abgespeicherte Nennwassermenge zur zugelaufenen Ist-Wassermenge.For easier handling when filling the storage container (3), the container can be provided with a filler neck (22). The filler neck (22) is mounted so that it can be inserted in an extension (23) of the storage container (3). In the position inserted in the extension (23), the filler neck (22) closes the storage container (3). In the extended position, it offers a large opening for easy filling of the storage container (3). By the Pulling out the filler neck (22) from the extension (23), the filler neck (22) is automatically opened and enlarged.
So that the laundry treatment agent does not reach the filling nozzle (22) when it is filled into the storage container (3), there is an optical "full display" (24) on the storage container (3).
In order to be able to push the container back into the housing after filling, the adjusting lever of the adjusting device (5) must be brought back into the correct angular position in relation to the direction of insertion so that the program control device (10) is signaled which type of laundry treatment agent has been filled .
In an advantageous development of the invention, the program-based addition of the laundry treatment agent is controlled by an automatic dosing within the program control (10). The metered amount is calculated depending on the amount of water that has flowed in at the beginning of the first wash cycle. Nominal water quantities for the different washing programs and program sections are stored in a table of values as the basis for calculating the dosing quantity. The amount of water that flows in at the beginning of the first wash cycle is recorded and compared with the stored nominal amounts of water in accordance with the program selection. If z. B. less water has flowed in due to a lower loading quantity, the indicated and preselected metering quantity via the display device (11) decreases in the same ratio as the stored nominal water quantity to the inflowing actual water quantity.
