Abstract

The revolution speed of the pump is regulated during the filling of the appliance in accordance with the rising water volume.

Description

Die Erfindung betrifft ein wasserführendes Haushaltsgerät, insbesondere eine Haushalt- Geschirrspülmaschine, mit einer Umwälzpumpe, die zumindestens zeitweise beim Befüllen des Haushaltsgerätes betrieben wird.The invention relates to a water-bearing household appliance, in particular a household Dishwasher, with a circulation pump, which at least at times when filling of the household appliance is operated.

Wasserführende Haushaltsgeräte der eingangs genannten Art sind bekannt, z. B. aus der DE-OS 40 26 868, die eine Haushalt-Geschirrspülmaschine beschreibt, bei der das Befüllen der Haushalt-Geschirrspülmaschine so lange andauert, bis der Rundlauf der Umwälzpumpe erreicht ist, d. h. bis genügend Flüssigkeit eingefüllt ist, daß bei voller Pumpenleistung der Normalbetrieb gewährleistet ist. Diese Vorgehensweise wird üblicherweise dynamisches Befüllen genannt.Water-bearing household appliances of the type mentioned are known, for. B. from the DE-OS 40 26 868, which describes a household dishwasher in which the filling the household dishwasher continues until the circulation pump runs smoothly is reached, d. H. until enough liquid is filled in that the full pump capacity Normal operation is guaranteed. This approach is usually dynamic Called filling.

Da die Umwälzpumpe bei einer dynamischen Befüllung z. B. nach der DE-OS 40 26 868 ständig mit voller Pumpenleistung betrieben wird, wird so lange der Rundlauf der Umwälz­ pumpe noch nicht erreicht ist, ein wesentlich höheres Geräusch, insbesondere durch Ge­ räuschspitzen, entwickelt, als im Normalbetrieb mit ausreichender Flüssigkeitsmenge. Der Erfindung liegt daher die Aufgabe zugrunde, bei einem wasserführenden Haushaltsgerät der eingangs genannten Art beim Befüllen auf einfache Art und Weise eine erhöhte Geräu­ schentwicklung zu vermeiden.Since the circulation pump with a dynamic filling z. B. according to DE-OS 40 26 868 is continuously operated with full pump capacity, the circulation runs as long as pump has not yet been reached, a much higher noise, especially by Ge noise peaks, developed as in normal operation with sufficient amount of liquid. The invention is therefore based on the object in a water-carrying household appliance of the type mentioned at the outset when filling in a simple manner an increased noise to avoid development.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehzahl der Umwälzpumpe regelbar ist, wobei die Drehzahl der Umwälzpumpe während des Befüllens entsprechend der ansteigenden Wassermenge auf Vollastbetrieb geregelt wird.This object is achieved in that the speed of the circulation pump is adjustable, the speed of the circulation pump during filling according to the increasing amount of water is regulated to full load operation.

Dadurch, daß die Drehzahl und damit die Förderleistung der Umwälzpumpe dem Wasser­ stand angepaßt wird, kommt es nicht zum Ansaugen von Luft und anderen denkbaren Stö­ rungen, die unweigerlich zu den genannten Geräuschspitzen führen und eine erhöhte Ge­ räuschentwicklung während des Befüllens des erfindungsgemäßen wasserführenden Haus­ haltsgerätes verursachen. Mit der Erfindung wird bei einem wasserführenden Haushaltsgerät der eingangs genannten Art beim Befüllen auf einfache Art und Weise eine erhöhte Geräusch­ entwicklung vermieden.The fact that the speed and thus the delivery rate of the circulation pump to the water was adjusted, there is no suction of air and other conceivable disturbances stances that inevitably lead to the noise peaks mentioned and an increased Ge Noise development during the filling of the water-bearing house according to the invention cause holding device. With the invention is in a water-bearing household appliance  of the type mentioned at the beginning of filling in a simple manner an increased noise development avoided.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles einer Haushalt- Geschirrspülmaschine erläutert.The invention is described below using an exemplary embodiment of a household Dishwasher explained.

Eine erfindungsgemäße Haushalt-Geschirrspülmaschine weist eine Umwälzpumpe auf, die zumindestens zeitweise beim Befüllen der Haushalt-Geschirrspülmaschine betrieben wird. Dies erfolgt im Ausführungsbeispiel dadurch, daß die Haushalt-Geschirrspülmaschine zu Beginn eines Reinigungsprogrammabschnittes mit Flüssigkeitseinsatz bei nicht betriebener Umwälzpumpe mit etwa 3 Liter Wasser gefüllt wird, was üblicherweise als statisches Befül­ len bezeichnet wird. Nun wird die Umwälzpumpe eingeschaltet und bei einer Drehzahl be­ trieben, die bei etwa 3 Liter Wasser einen Vollastbetrieb der Pumpe bedeutet. Entsprechend der während der Fortdauer des Befüllvorganges der Haushalt-Geschirrspülmaschine anstei­ genden Wassermenge wird nun die Drehzahl der Umwälzpumpe so geregelt, daß sich im­ mer ein Vollastbetrieb einstellt. Diese wird so lange fortgesetzt, bis die maximale Drehzahl der Umwälzpumpe erreicht ist. Da sich dann der Vollastbetrieb am eigentlichen Arbeitspunkt der Umwälzpumpe eingestellt hat, kann auch das Befüllen der Haushalt-Geschirrspül­ maschine beendet werden.A household dishwasher according to the invention has a circulation pump which is operated at least temporarily when filling the household dishwasher. In the exemplary embodiment, this takes place in that the household dishwasher is closed Start of a cleaning program section with the use of liquid when not in use Circulation pump is filled with about 3 liters of water, which is usually a static fill len is called. Now the circulation pump is switched on and at a speed driven, which means full load operation of the pump at about 3 liters of water. Corresponding which increases during the filling process of the household dishwasher The amount of water is now regulated the speed of the circulation pump so that always a full load operation. This continues until the maximum speed the circulation pump is reached. Since then the full load operation at the actual working point of the circulation pump can also be used to fill the household dishwasher machine are stopped.

Dadurch, daß die Drehzahl und damit die Förderleistung der Umwälzpumpe dem Wasser­ stand angepaßt wird, kommt es nicht zum Ansaugen von Luft und anderen denkbaren Stö­ rungen, die unweigerlich zu den genannten Geräuschspitzen führen und eine erhöhte Ge­ räuschentwicklung während des Befüllens des erfindungsgemäßen wasserführenden Haus­ haltsgerätes verursachen. Mit der Erfindung wird bei einem wasserführenden Haushaltsgerät der eingangs genannten Art beim Befüllen auf einfache Art und Weise eine erhöhte Geräusch­ entwicklung vermieden.The fact that the speed and thus the delivery rate of the circulation pump to the water was adjusted, there is no suction of air and other conceivable disturbances stances that inevitably lead to the noise peaks mentioned and an increased Ge Noise development during the filling of the water-bearing house according to the invention cause holding device. With the invention is in a water-bearing household appliance of the type mentioned at the beginning of filling in a simple manner an increased noise development avoided.
