Abstract

Programme-controlled washing machine or dishwasher with an ion exchanger for water softening and with a salt-supply container for regenerating the ion-exchanger mass. The ion exchanger is connected to fresh water via a water inflow which is controlled by a valve switched by the programme control unit of the machine. The opening duration of the valve in the water inflow to the ion exchanger is recorded by means of a time meter. The recorded opening duration of the valve serves as a measure for initiating the operation of regenerating the ion exchanger.

Description

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

Es ist z. B. bei gewerblichen Waschmaschinen be­ kannt, die Waschlauge mit enthärtetem Wasser anzuset­ zen, das zu diesem Zweck über einen Ionenaustauscher (Wasser-Enthärter) geführt wird. Solche Ionenaustau­ scher müssen nun des öfteren regeneriert werden, was durch Zuführen einer entsprechenden Solemenge aus einem dem Ionenaustauscher vorgeschalteten Salzvor­ ratsbehälter bewirkt wird.It is Z. B. in commercial washing machines knows to add the detergent solution with softened water zen, for this purpose via an ion exchanger (Water softener) is performed. Such ion exchange shear now have to be regenerated what by supplying an appropriate amount of brine a salt upstream of the ion exchanger advice container is effected.

Aufgabe der Erfindung ist es nun, einen Weg aufzu­ zeigen, durch den sichergestellt ist, daß der Regenerie­ rungsvorgang für den Ionenaustauscher erst nach des­ sen vollständiger Ausnutzung eingeleitet wird.The object of the invention is now to find a way show by which it is ensured that the regeneration process for the ion exchanger only after the full exploitation is initiated.

Die Lösung dieser Aufgabe besteht nun darin, daß die Öffnungsdauer des Ventils im Wasserzulauf zum Ionen­ austauscher mittels eines Zeitmeßgerätes erfaßt und die erfaßte Öffnungsdauer des Ventils als Maß für die Ein­ leitung des Regenerierungsvorganges für den Ionenaus­ tauscher herangezogen wird.The solution to this problem is that the Opening time of the valve in the water supply to the ion exchangers detected by a timepiece and the detected opening time of the valve as a measure of the on Management of the regeneration process for the ion exchanger is used.

Durch diese Maßnahme wird eine optimale Ausnut­ zung des Ionenaustauschers und gleichzeitig eine Ein­ sparung von Regenerierungssalz erreicht, da die Rege­ nerierung des Ionenaustauschers auf die von diesem tat­ sächlich gelieferte Weichwassermenge bzw. auf dessen maximalste Ergiebigkeit abgestellt ist. Als Zeitmeßgerät kann dabei ein mechanisches Zeitschaltwerk üblicher Bauart Verwendung finden, das elektrisch parallel zum Stromkreis für das Ionenaustauscher-Ventil geschaltet ist. Ist die Ergiebigkeit des Ionenaustauschers z. B. für 60 l enthärtetes Wasser (Weichwasser) bei etwa 21 Grad deutscher Härte (21° D. H.) ausgelegt, so gibt bei einem Ventildurchsatz von IO l/min das Zeitmeßgerät dann nach ca. 6 min. ein Signal (Kommando) an das Programmschaltwerk der betreffenden Waschmaschine zur Einleitung des Regenerierungsvorganges ab und bleibt dann selbst stehen. Nach Beendigung des Rege­ nerierungsvorgangs wird das Zeitmeßgerät wieder be­ triebsbereit (zählbereit) geschaltet und zählt wieder die Öffnungsdauer des Ionenaustauscher-Ventils. Wie aus den vorstehenden Ausführungen hervorgeht, wird die Einleitung des Regenerierungsvorgang für den Ionen­ austauscher (Wasserenthärter) zweckmäßig in Abhän­ gigkeit von der durch diesen geförderten Frischwasser­ menge gesteuert. Besonders vorteilhaft ist es, einen mit dem Zeitmeßgerät zusammenwirkenden Eingabeschal­ ter vorzusehen, über den der jeweilige Härtegrad des Frischwassers vorgegeben werden kann. Damit wird er­ reicht, daß auch die Wasserhärte als zusätzliches Maß für die Einleitung des Regenerierungsvorganges beim Ionenaustauscher mit berücksichtigt wird.This measure ensures optimum utilization of the ion exchanger and, at the same time, a saving of regeneration salt, since the regeneration of the ion exchanger is based on the amount of soft water actually supplied by the latter or on its maximum yield. A mechanical time switch of conventional design can be used as the time measuring device, which is electrically connected in parallel to the circuit for the ion exchanger valve. Is the yield of the ion exchanger z. B. designed for 60 l softened water (soft water) at about 21 degrees German hardness ( 21 ° DH), then with a valve throughput of IO l / min the timepiece is then after about 6 min. a signal (command) to the program switch of the washing machine in question to initiate the regeneration process and then stops itself. After completion of the regeneration process, the timepiece is switched back to ready for operation (ready to count) and counts the opening time of the ion exchanger valve again. As can be seen from the above, the initiation of the regeneration process for the ion exchanger (water softener) is expediently controlled as a function of the amount of fresh water conveyed by it. It is particularly advantageous to provide an input switch which interacts with the time measuring device and via which the respective degree of hardness of the fresh water can be predetermined. It is enough that the water hardness is also taken into account as an additional measure for the initiation of the regeneration process in the ion exchanger.
