Abstract

To ensure a good rinsing result, the duration of the rinsing operation commences when rinsing water is fed for the last time.

Description

Die Erfindung betrifft eine Waschmaschine mir einer Programmsteuereinrichtung, die zum Zwecke des Spülens eine Spülwasserzulaufeinrichtung und die festgelegte Dauer des Spülganges zeit- und/oder wasserstandabhängig steuert.The invention relates to a washing machine with a program control device, the for the purpose of rinsing, a rinse water supply device and the specified duration controls the rinse cycle depending on time and / or water level.

Bei modernen Waschmaschinen, die mit niedrigem Wasserstand waschen und spülen und zwischen zwei oder mehreren Spülgängen Spülwasser aus der Wäsche ausschleu­ dern, kann beim Nachziehen von Wasser in die Wäsche ein Spülwassermangel in der Wäsche auftreten. Die entsprechenden Spülergebnisse sind daher abhängig von der Art und der Menge der in die Trommel eingelagerten Wäsche einer großen Schwan­ kungsbreite unterworfen.In modern washing machines that wash and rinse at low water levels and rinse out rinsing water from the laundry between two or more rinse cycles If water is drawn into the laundry, there may be a lack of rinse water in the Laundry occur. The corresponding washing results are therefore dependent on the Type and amount of laundry stored in the drum of a large swan width.

Der Erfindung liegt die Aufgabe zugrunde, für immer gleich gute Spülergebnisse un­ ter Vermeidung großer Schwankungsbreiten zu sorgen.The invention is based, to achieve the same good washing results un to avoid large fluctuations.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Dauer des Spülganges beim letztmaligen Spülwasserzulauf beginnt. Die Erfindung geht von der Beobachtung aus, daß stark saugfähige Wäsche (nach Art oder Menge) nach einem sogenannten Zwischenschleudergang so viel Wasser aufnimmt, daß der Spülwasserzulauf in jedem Spülgang mindestens ein zweites Mal eingeschaltet werden muß, um den insgesamt erforderlichen Spülwasser-Bedarf zu befriedigen. Bis zur Ergänzung dieses Spülwas­ sers läuft in den bekannten Waschmaschinen jedoch bereits ein Teil des Spülganges ohne volle Wirkung ab, so daß die Spülwirkung jedes Spülganges unzureichend bleibt. Wird die Dauer jedes Spülganges gemäß der Erfindung dagegen erst vom letztmaligen Spülwasserzulauf an berechnet, dann kann mit großer Wahrscheinlichkeit davon aus­ gegangen werden, daß während der gesamten vorgesehenen Dauer des Spülganges ge­ nügend Spülwasser für die Wäsche vorhanden war.According to the invention, this object is achieved in that the duration of the rinse cycle starts with the last rinse water supply. The invention is based on observation from that highly absorbent laundry (by type or amount) according to a so-called Intermediate spin cycle absorbs so much water that the rinse water inlet in each Rinse cycle must be switched on at least a second time to make up the total to satisfy the need for rinse water. Until this rinse was added However, part of the rinse cycle is already running in the known washing machines without full effect, so that the rinsing effect of each rinse remains inadequate. However, the duration of each rinse cycle according to the invention is only the last time Rinse water inflow calculated, then it can be assumed with a high probability be gone that ge throughout the intended duration of the rinse cycle there was not enough rinse water for the laundry.

Gemäß einer besonders vorteilhaften Ausbildung der Erfindung überschreitet die Gesamtzeit vom ersten Spülwasserzulauf bis zum Ende des Spülganges eine vorbe­ stimmte Maximaldauer nicht. Hierdurch können gegebenenfalls vorliegende Fehler überspielt werden, die möglicherweise ein endloses Spülen verursachen würden.According to a particularly advantageous embodiment of the invention, the Total time from the first rinse water inlet to the end of the rinse cycle maximum duration was wrong. This may cause errors dubbed, which would possibly cause an endless rinse.

Bei elektromechanischen Programmsteuereinrichtungen kann der Fortlauf der jeden Spülgang steuernden Programmscheibe unterbrochen werden und diese Programm­ scheibe durch ein Überfahren wieder in ihre Anfangsposition bewegt werden, wenn ein Magnetventil zum Zwecke des Spülwasserzulaufes erneut eingeschaltet wird.With electromechanical program control devices, the progress of everyone Program disc controlling the rinse cycle are interrupted and this program can be moved back to their starting position by running over, if a solenoid valve is switched on again for the purpose of flushing water supply.

Mit erheblich weniger Aufwand kann eine erfindungsgemäße Spülgang-Steuerung mit­ tels einer elektronischen Programmsteuereinrichtung bewerkstelligt werden, weil das elektronische Rücksetzen eines zeitabhängig steuernden Zählers beim Registrieren ei­ ner erneuten Magnetventil-Schaltung praktisch ohne Zeitverzögerung vorgenommen werden kann. An inventive rinse control can be carried out with considerably less effort be accomplished by an electronic program control device because that electronic reset of a time-dependent counter when registering ner renewed solenoid valve switching made practically without time delay can be.  

Besonders vorteilhaft wird der Beginn des Spülganges auf das Ende des letztmaligen Spülwasserzulaufs gelegt. Beispielsweise kann der Spülgang exakt zusammen mit dem Abschalten des Magnetventils beginnen. In diesem Falle wird die Zulaufzeit, die ebenfalls Schwankungen unterworfen sein kann, nicht in den Spülgang eingerechnet.The start of the rinse cycle at the end of the last one is particularly advantageous Rinsing water inlet laid. For example, the rinse cycle can be carried out together with the Start switching off the solenoid valve. In this case, the inflow time is the can also be subject to fluctuations, not included in the rinse cycle.
