Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Waschmaschine, insbesondere einer Trommelwaschmaschine, umfassend eine Wäschetrommel (4) zur Aufnahme der zu waschenden Wäsche, eine Zuführvorrichtung für das in den Laugenbehälter (3) einzuleitende Frischwasser, ein im Laugenbehälter (3) angeordneter Heizkörper (6) für das Aufheizen des Waschwassers, der ebenfalls als Heizvorrichtung zur Dampferzeugung für das Behandeln der Wäsche mit Dampf dient, eine Ablaufpumpe (9) für das Abpumpen des Brauchwassers über das im Gehäuse der Waschmaschine (1) angeordnete Abwassersystem, eine Steuerungsvorrichtung (13), durch die in Verbindung mit einem Wasserstandssensor (5) die programmgemäß vorgesehenen Wasserstände in der Maschine eingestellt werden.The invention relates to a method for operating a washing machine, in particular a drum washing machine, comprising a laundry drum (4) for receiving the laundry to be washed, a supply device for the fresh water to be introduced into the tub (3), a heating element (6) arranged in the tub (3) ) for the heating of the wash water, which also serves as a heater for steam generation for treating the laundry with steam, a drain pump (9) for pumping out the process water via the in the housing of the washing machine (1) arranged wastewater system, a control device (13), through which, in conjunction with a water level sensor (5) the water levels are set in the machine according to the program.

Erfindungsgemäß ist in einer ersten Ausführungsform vorgesehen, dass als Ablaufpumpe (9) eine drehzahlregelbare Pumpe verwendet wird, deren Drehzahl so gesteuert werden kann, dass ein Teil des im Laugenbehälter (3) befindlichen Wassers in Leerräume des innerhalb der Waschmaschine vorhandenen Abwassersystems befördert werden kann ohne dass dies nach außen abgepumpt wird. Durch einen Wasserstandssensor (5) in Verbindung mit einer Steuerungsvorrichtung (13) dadurch ein definierter Wasserstand (H1) eingestellt werden, mit dem eine effiziente Dampferzeugung ermöglicht wird.According to the invention, it is provided in a first embodiment that a speed-controllable pump is used as drain pump (9), whose speed can be controlled so that a part of the water in the tub (3) can be transported in voids of existing within the washing machine sewer system without that this is pumped outwards. By a water level sensor (5) in conjunction with a control device (13) thereby a defined water level (H1) can be adjusted, with which an efficient steam generation is made possible.

Bei der zweiten Ausführungsform befindet sich der Heizkörper durch intermittierendes Ein- und Ausschalten Ablaufpumpe (9) kurzzeitig und wechselweise einmal im und einmal außerhalb des Wassers. Dadurch kommt es zu einem impulsweise ablaufenden Verdampfungsprozess des am Heizkörper (6) anhaftenden Restwassers.

Figure imgaf001
In the second embodiment, the radiator is by intermittent switching on and off drain pump (9) for a short time and alternately once in and once outside the water. This leads to a pulsed running evaporation process of the radiator (6) adhering residual water.
