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 mit einem mehrgängigen Spülprogrammabschnitt und einer Programmsteuereinrichtung, die zum Zwecke des Spülens eine Spülwasserzulaufeinrichtung und die festgelegte Dauer jedes Spülganges zeit- und/oder wasserstandabhängig steuert.The invention relates to a washing machine with a multi-start washing program section and a program control device which controls a washing water supply device for the purpose of washing and the specified duration of each washing cycle as a function of time and / or water level.

Bei modernen Waschmaschinen, z.B. Siemens "Siwamat" Typ 580, 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.In modern washing machines, e.g. Siemens "Siwamat" type 580, who wash and rinse at low water levels and eject rinsing water from the laundry between two or more rinsing cycles, may experience a lack of rinsing water in the laundry when water is drawn into the laundry. The corresponding washing results are therefore subject to a wide range of fluctuation, depending on the type and amount of laundry stored in the drum.

Der Erfindung liegt die Aufgabe zugrunde, für immer gleich gute Spülergebnisse unter Vermeidung großer Schwankungsbreiten zu sorgen.The invention has for its object to ensure consistently good washing results while avoiding large fluctuation ranges.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Dauer jedes Spülganges vom jeweils letzten Spülwasserzulauf an berechnet wird. 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 Maschmaschinen 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.According to the invention, this object is achieved in that the duration of each rinse cycle is calculated from the last rinse water inlet. The invention is based on observation from the fact 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 effect 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.

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.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 does not exceed a predetermined maximum duration. In this way, any errors that may be present, which would possibly cause endless rinsing, can be transferred.

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.In the case of electromechanical program control devices, 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.

Mit erheblich weniger Aufwand kann eine erfindungsgemäße Spülgang-Steuerung mitteils 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.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 with practically no time delay.

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 is particularly advantageously placed at the end of the last rinse water inlet. For example, the rinse cycle can begin exactly when the solenoid valve is switched off. In this case, the inflow time, which may also be subject to fluctuations, is not included in the rinse cycle.

Claims (3)

  1. Washing machine with a multiple rinsing program portion and a program control equipment which controls a rinsing water inflow equipment and the fixed duration of each rinsing run in dependence on time and/or water level for the purpose of the rinsing, characterised, thereby, that the duration of each rinsing run is computed from the respectively last rinsing water inflow.
  2. Washing machine according to claim 1, characterised thereby, that the total time from the first rinsing water inflow to the end of the rinsing run does not exceed a predetermined maximum duration.
  3. Washing machine according to claim 1 or 2, characterised thereby, that the rinsing run begins with the end of the last rinsing water inflow.
