Definitions
- the invention relates to a washing machine with a program control device which controls a rinse water supply device for the purpose of rinsing and the specified duration of the rinse cycle as a function of time and / or water level.
- this object is achieved in that the duration of the rinse cycle begins with the last rinse water supply.
- the invention is based on the observation that highly absorbent laundry (by type or quantity) absorbs so much water after a so-called intermediate spin cycle that the rinse water supply must be switched on at least a second time in each rinse cycle in order to satisfy the total rinse water requirement . Until this rinse water is supplemented, however, part of the rinse cycle already takes place in the known washing machines without full effect, so that the rinse action of each rinse cycle remains inadequate. If, on the other hand, the duration of each rinse cycle according to the invention is only calculated from the last rinse water inlet, then it can be assumed with a high degree of probability that sufficient rinse water was available for the laundry during the entire intended duration of the rinse cycle.
- the total time from the first rinse water inlet to the end of the rinse cycle does not exceed a predetermined maximum duration. In this way, any errors that may be present, which could possibly cause endless rinsing, can be transferred.
- the progress of the program disk controlling each wash cycle can be interrupted and this program disk can be moved back to its starting position by driving over it when a solenoid valve is switched on again for the purpose of the rinse water supply.
- a rinse cycle control according to the invention can be accomplished with considerably less effort by means of an electronic program control device, because the electronic resetting of a time-dependent counter when registering a renewed solenoid valve circuit can be carried out practically without a time delay.
- the start of the rinse cycle is particularly advantageously placed at the end of the last rinse water inlet.
- the rinse cycle can begin exactly when the solenoid valve is switched off.
- the inflow time which can also be subject to fluctuations, is not included in the rinse cycle.

Abstract
Description
- Die Erfindung betrifft eine Waschmaschine mit einer Programmsteuereinrichtung, die zum Zwecke des Spülens eine Spülwasserzulaufeinrichtung und die festgelegte Dauer des Spülganges zeit- und/oder wasserstandabhängig steuert.
- Bei modernen Waschmaschinen, die mit niedrigem Wasserstand waschen und spülen und zwischen zwei oder mehreren Spülgängen Spülwasser aus der Wäsche ausschleudern, 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 Schwankungsbreite unterworfen.
- Der Erfindung liegt die Aufgabe zugrunde, für immer gleich gute Spülergebnisse unter Vermeidung großer Schwankungsbreiten zu sorgen.
- 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 Spülwassers 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 ausgegangen werden, daß während der gesamten vorgesehenen Dauer des Spülganges genügend Spülwasser für die Wäsche vorhanden war.
- Gemäß einer besonders vorteilhaften Ausbildung der Erfindung überschreitet die Gesamtzeit vom ersten Spülwasserzulauf bis zum Ende des Spülganges eine vorbestimmte Maximaldauer nicht. Hierdurch können gegebenenfalls vorliegende Fehler überspielt werden, die möglicherweise ein endloses Spülen verursachen würden.
- Bei elektromechanischen Programmsteuereinrichtungen kann der Fortlauf der jeden Spülgang steuernden Programmscheibe unterbrochen werden und diese Programmscheibe durch ein Überfahren wieder in ihre Anfangsposition bewegt werden, wenn ein Magnetventil zum Zwecke des Spülwasserzulaufes erneut eingeschaltet wird.
- Mit erheblich weniger Aufwand kann eine erfindungsgemäße Spülgang-Steuerung mittels einer elektronischen Programmsteuereinrichtung bewerkstelligt werden, weil das elektronische Rücksetzen eines zeitabhängig steuernden Zählers beim Registrieren einer erneuten Magnetventil-Schaltung praktisch ohne Zeitverzögerung vorgenommen werden kann.
- 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.
