Abstract
In einer Waschmaschine wird bekanntermaßen am Meßort eines optischen Trübungssensors 5, 6 die Trübung einer Spülflüssigkeit 7 gemessen und der weitere Spülprozeß anhand des gemessenen Trübungswertes von einer Programmsteuereinrichtung festgelegt. Zur verbesserten Überwachung und Steuerung des Spülprozesses wird der Trübungssensor 5, 6 außerdem zur Schaumerkennung verwendet, wenn sich keine Spülflüssigkeit 7 an seinem Meßort befindet. Wenn Schaum 8 am Meßort des Trübungssensors 5, 6 erkannt wird, können beispielsweise weitere Spülgange vorgesehen werden. In einem solchen Fall kann auch der Spülprozeß intensiviert oder können die Schaumbildung fördernde Einflüsse ausgeschaltet oder verringert werden. As is known, the turbidity of a rinsing liquid 7 is measured in a washing machine at the measuring location of an optical turbidity sensor 5, 6 and the further rinsing process is determined by a program control device on the basis of the measured turbidity value. For improved monitoring and control of the washing process, the turbidity sensor 5, 6 is also used for foam detection when there is no washing liquid 7 at its measuring location. If foam 8 is detected at the measurement location of the turbidity sensor 5, 6, further rinse cycles can be provided, for example. In such a case, the rinsing process can also be intensified, or influences that promote foam formation can be switched off or reduced.
