Abstract

Programme-controlled washing machine or dishwasher with an ion exchanger (15) for water softening and with a salt-supply container (14) for regenerating the ion-exchanger mass. The salt-supply container (14) is connected to the fresh-water feedline via a branch line controlled by a valve switched by the programme control unit of the machine. Inserted in the branch line (13) is a water-supply container (20) which, while the ion exchanger (15) is in operation, is filled in a specific period of time with a specific dispensed quantity of leaking water from its fresh-water supply line (10'). The water-supply container (20) is assigned a filling-level monitoring device (21) which, when a specific filling level is reached, gives the programme control unit a signal for initiating the operation of regenerating the ion exchanger (15). <IMAGE>

Description

Die Erfindung betrifft eine programmgesteuerte Wasch- oder Geschirrspülmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a program-controlled washing machine or dishwasher according to the preamble of claim 1.

Es ist z. B. bei gewerblichen Waschmaschinen bekannt, die Waschlauge mit enthärtetem Wasser anzusetzen, das zu diesem Zweck über einen Ionenaustauscher (Wasser-Enthärter) geführt wird. Solche Ionenaustauscher müssen nun des öftern regeneriert werden, was durch Zuführen einer entsprechenden Solemenge aus einem dem Ionenaustauscher vorgeschalteten Salzvorratsbehälter bewirkt wird.It is Z. B. known in commercial washing machines, the wash liquor apply softened water, which is done for this purpose via an ion exchanger (Water softener) is performed. Such ion exchangers must now are often regenerated, which is done by supplying an appropriate Amount of brine from a salt reservoir upstream of the ion exchanger is effected.

Aufgabe der Erfindung ist es nun, einen Weg aufzuzeigen, durch den sichergestellt ist, daß der Regenerierungsvorgang für den Ionenaustauscher erst nach dessen vollständiger Ausnutzung eingeleitet wird.The object of the invention is now to show a way by which ensured is that the regeneration process for the ion exchanger only after full utilization of which is initiated.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruches 1 zu entnehmen.The solution to this problem according to the invention is the characterizing part of claim 1.

Zweckmäßige weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further developments of the subject matter of the invention are in specified in the subclaims.

Durch die Erfindung wird erreicht, daß über eine Füllstandsüberwachungseinrichtung, die Bestandteil eines während einer genau festgelegten Zeitdauer gefüllten Wasservorratsbehälters ist, dem Programmschaltwerk der betreffenden Haushaltsmaschine ein Signal zum Einleiten des Regenerierungsvorganges für den Ionenaustauscher gegeben wird. Die Füllung des Wasservorratsbehälters dient damit als Maß zur Einleitung des Regenerierungsvorganges.It is achieved by the invention that, via a fill level monitoring device,  the component of a during a precisely defined period of time filled water reservoir, the program switch of concerned household machine a signal to initiate the regeneration process is given for the ion exchanger. The filling of the water reservoir thus serves as a measure to initiate the regeneration process.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend näher beschrieben. Der Beschreibung liegt dabei ein in der Zeichnung dargestellter Wasserführungsplan für eine Waschmaschine als bevorzugtes Ausführungsbeispiel zugrunde.An embodiment of the invention is described in more detail below. The description is one shown in the drawing Water routing plan for a washing machine as a preferred embodiment underlying.

Mit 10 ist eine Frischwasserzuleitung bezeichnet, die Bestandteil einer nicht dargestellten Haushalts-Waschmaschine üblicher Bauart mit einer zusätzlichen Wasserenthärtungs-Einrichtung ist. Von der Frischwasserzuleitung 10 geht eine Abzweigung 11 mit Ventil V 7 zu einem Waschmitteleinspülbehälter 12. Ein solcher Waschmitteleinspülbehälter 12 besitzt üblicher Weise drei Behandlungsmittel- Einspülkammern, von denen eine das Mittel für die Vorwäsche (Vorwaschgang), eine das Mittel für die Hauptwäsche (Hauptwaschgang) und eine das Mittel für den Weichspülgang enthält. Jeder Einspülkammer ist ein Wasserzulauf mit einem Ventil V 3, V 4, V 5 (Magnetventil) zugeordnet. Eine weitere Abzweigleitung 13 mit Ventil V 1 führt zu einem Salzvorratsbehälter, der einem Ionenaustauscher 15 (Wasser-Enthärter) vorgeschaltet ist. Beide Teile (14, 15) sind durch eine Leitung 16 miteinander verbunden, in der sich ein die Leitung 16 in Richtung zum Salzvorratsbehälter 14 hin verschließendes Rückschlagventil 17 befindet. Der Ionenaustauscher 15 ist wiederum dem Waschmitteleinspülbehälter 12 vorgeschaltet, wobei von dessen Verbindungsleitung 18 eine zur Entleerungspumpe führende Ausspülleitung 19 mit Ventil V 6 abgeht. Die Frischwasserzuleitung 10 endet am Ionenaustauscher 15, wobei ein Ventil V 2 den Weg zum Ionenaustauscher 15 beherrscht.With 10 a fresh water supply line is designated, which is part of a household washing machine of the usual type, not shown, with an additional water softening device. A branch 11 with valve V 7 leads from the fresh water supply line 10 to a detergent dispenser container 12 . Such a detergent dispenser container 12 usually has three treatment agent dispensing chambers, one of which contains the agent for the prewash (prewash cycle), one contains the agent for the main wash (main wash cycle) and one contains the agent for the fabric softener cycle. A water inlet with a valve V 3 , V 4 , V 5 (solenoid valve) is assigned to each induction chamber. Another branch line 13 with valve V 1 leads to a salt reservoir, which is connected upstream of an ion exchanger 15 (water softener). Both parts ( 14, 15 ) are connected to one another by a line 16 in which there is a check valve 17 which closes the line 16 in the direction of the salt reservoir 14 . The ion exchanger 15 is in turn connected upstream of the detergent dispenser 12 , from whose connecting line 18 a flushing line 19 leading to the drain pump with valve V 6 goes out. The fresh water supply line 10 ends at the ion exchanger 15 , a valve V 2 controlling the path to the ion exchanger 15 .

In der Abzweigleitung 13 ist ein Wasservorratsbehälter 20 mit bodenseitigem Rückschlagventil zwischengeschaltet, der während der Inbetriebnahme des Ionenaustauschers 15 durch eine definiert abgegebene Leckwassermenge aus der Frischwasserzuführleitung 10′ des Ionenaustauschers in einer bestimmten Zeitdauer gefüllt wird. Dem Wasservorratsbehälter 20 ist eine Füllstandsüberwachungseinrichtung 21 zugeordnet, durch die mit Erreichen einer bestimmten Füllstandshöhe dem Programmschaltwerk ein Signal zur Einleitung des Regenerierungsvorganges für den Ionenaustauscher 15 gegeben wird. Der Regenerierungsvorgang beginnt mit Öffnen des Ventils V 1. Dabei wird gleichzeitig der Wasservorrat aus dem Behälter 20 in den Salzvorratsbehälter 14 gefördert. Die dem Wasservorrat entsprechende Solemenge wird über die Leitung 16 in und damit durch den Ionenaustauscher 15 gefördert. Zur Förderung des Wasservorrats in den Salzvorratsbehälter 14 ist eine entsprechende Pumpe vorgesehen.In the branch line 13 , a water reservoir 20 with a bottom-side check valve is interposed, which is filled during the commissioning of the ion exchanger 15 by a defined amount of leaked water from the fresh water supply line 10 'of the ion exchanger. A fill level monitoring device 21 is assigned to the water storage container 20 , by means of which a signal to initiate the regeneration process for the ion exchanger 15 is given to the program switch when a certain fill level is reached. The regeneration process begins when valve V 1 is opened . At the same time, the water supply is conveyed from the container 20 into the salt storage container 14 . The amount of brine corresponding to the water supply is conveyed via the line 16 into and thus through the ion exchanger 15 . A corresponding pump is provided to convey the water supply into the salt storage container 14 .
