Verfahren zur Kühlung des Ablauf wassers einer Waschmaschine.Process for cooling the drainage water of a washing machine.
Die Erfindung bezieht sich auf ein Verfahren zur Kühlung des Ablaufwassers einer Waschmaschine. ■ -The invention relates to a method for cooling of the drainage water from a washing machine. ■ -
Das während des Waschvorganges aus der Waschmaschine tretende Wasser erreicht bekanntlich in vielen Fällen Temperaturwerte, die zu Verbrühungen führen können. Da .nun bei vielen Waschanlagen das heiße Ablauf wasser inrWaschbecken oder Badewannen abrinnt, besteht für viele Personen Verbrühungsgefahr. Das Wasser läuft plötzlich und gewöhnlich in großer Menge ab. Zur Beseitigung dieses Nachteils wurde bereits vorgeschlagen, dem im Waschabteil der Waschmaschine enthaltenen heißen Wasser vor dem Ablassen desselben eine Menge Kaltwasser hinzuzufügen. Dies hat sich jedoch deshalb als nachteilig und nicht durchführbar erwiesen, weil sich gezeigt hat, daß durch die Abkühlung des im Waschabteil.enthaltenen Wassers ein neuerliches, Absetzen von Stoffen auf der Wäsche hervorgerufen wird, die bei höheren Temperaturen im Wasser aufgelöst sind.That which comes out of the washing machine during the washing process It is well known that in many cases water reaches temperatures that can lead to scalding. There. Now with many car washes the hot drainage water in the washbasin or bathtub runs off, there is a risk of scalding for many people. The water runs suddenly and usually in great abundance away. To eliminate this disadvantage, it has already been proposed to use the hot one contained in the washing compartment of the washing machine Add a lot of cold water to the water before draining it. However, this has therefore been disadvantageous and not proven to be feasible because it has been shown that the cooling of the water in the washing compartment causes a new, Deposition of substances on the laundry is caused, which are dissolved in the water at higher temperatures.
Die Erfindung hat den Zweck, eine Herabsetzung der Ablaufwassertemperatur herbeizuführen, ohne dabei diesen Nachteil hervorzurufen.The purpose of the invention is to lower the outlet water temperature bring about without causing this disadvantage.
Durch die Erfindung wird diese Aufgabe dadurch gelost, daß dem abzulassenden heißen Wasser eine Menge Kaltwasser an ei-The invention solves this problem in that add a lot of cold water to the hot water to be drained

rier Stelle der Abiaufleitung zugesetzt wird, die sich außerhalb und nach dem Waschabteil befindet und daß gleichzeitig die sich bildende Mischung von aus dem Waschabteil kommendem heißem Ablaufwasser und kaltem Wasser ablaufen gelassen wird. Die Vermischung zwischen heißem Wasser und Kaltwasser erfolgt vorzugsweise im Inneren des Filters vor der Ablaufpumpe. Der ! Zulauf des kalten Wassers aus der äußeren Wasserleitung wird W durch ein bei Ablauf des Waschwassers auf geeignete Weise gesteuertes Elektroventil kontrolliert.rier point of the drainage line is added, which is located outside and after the washing compartment and that at the same time the mixture of hot drainage water coming from the washing compartment and cold water is allowed to run off. The mixing between hot water and cold water takes place preferably inside the filter in front of the drain pump. The ! Inlet of cold water from the external water line W is controlled by a controlled in an appropriate manner at the end of the wash water solenoid valve.
In der Zeichnung ist ein Ausfuhrungsbeispiel einer das erfindungsgemäße Verfahren verwirklichenden Einrichtung schematisch dargestellt. In the drawing, an exemplary embodiment is the one according to the invention Process implementing device shown schematically.
Die Waschmaschine besteht aus einem Kasten 1, einem Waschabteil 2 und einer drehbaren Trommel 3. Vom Boden des Waschabteils geht eine axt Filter 5 ausgestattete Ablauf leitung 4 aus, wobei das Filter an der Ansaugstelle der Wasserablaufpumpe angebracht ist. .Ia Filter 5 mündet eine Wasserzulauf leitung 6 mit Elektroventil 7, das den Zulauf von kaltem Wasser in die Leitung 6 steuert. The washing machine consists of a box 1, a washing compartment 2 and a rotatable drum 3. From the bottom of the washing compartment goes an ax filter 5 equipped drain line 4, the filter attached to the suction point of the water drain pump is. .Ia filter 5 opens a water supply line 6 with Solenoid valve 7 that controls the supply of cold water into line 6.
Das Elektroventil 7 kann entweder durch den Stromkreis der j Ablaufpumpe oder vorzugsweise durch eine eigene Schaltung ί gesteuert werden. Im ersteren Fall würde nSmlich während des Ablaufes des Spül wasser s, das normalerweise kalt ist, ein über·» - flüssiger Wasserzulauf durch das Elektroventil 7 und die Leitung 6 stattfinden.The solenoid valve 7 can either through the circuit of the j Drain pump or preferably by means of a separate circuit ί be controlled. In the former case, namely during the The rinsing water, which is normally cold, drains over a · » - liquid water inlet through the solenoid valve 7 and the pipe 6 take place.

Wie eraichtlieh, kann das Kaltwasser keinerlei Einfluß auf die im Waschabteil herrschende Temperatur ausüben ■ und diese daher nicht herabsetzen, wodurch die Gefahr beseitigt ist, daft sich auf der bereite gewaschenen Wasche Stoffe wieder absetzen, die bei höheren Temperaturen in 'der Waschlauge gelöst sind.As it is easy to do, the cold water has no influence whatsoever to exercise the temperature in the washing compartment ■ and therefore do not diminish it, thereby eliminating the risk of getting on the ready-washed laundry Settle again substances that in 'the detergent solution are dissolved.
