Abstract

Method for the program control of a washing machine with a water inflow of regulated water level, in which the water quantity which flowed into the tub at the start of the washing program is detected by a measuring device, and in which different washing-process criteria, such as the water level, number of washing or rinsing cycles, washing-agent metering and the like, can be fixed in dependence on this inflow quantity. The measured values detected by the measuring device and dependent on the water level are fed to an evaluator and are processed by this in such a way that the measured level fluctuations per filling cycle (filling step) in the tub and the number of counter-recorded tub water refillings per washing stage are communicated to a computer. The communicated measured and signalled values are a measure of the absorbency of the type of laundry entered in the program control. The individual washing-program parameters for the particular type of laundry introduced are then determined from these in the computer.

Verfahren und Anordnung zur Programmsteuerung einer Waschmaschine Method and arrangement for program control of a washing machine

Die Erfindung betrifft ein Verfahren und eine Anordnung zur Programmsteuerung einer Waschmaschine nach dem Oberbegriff des PatentanspruchesThe invention relates to a method and an arrangement for program control a washing machine according to the preamble of claim

Bei den Waschmaschinen dieser Art läuft der Waschprozeß in der Regel nach einem festgeschriebenen Programm ab, welches im Hinblick auf den Wassereinsatz, Zeit der mechanischen Einwirkung, Temperatur und Waschmitteldosierung auf maximale Anforderungen abgestellt ist. Wünschenswert wäre jedoch die Durchführung eines Waschprogrammes, in dem der tatsächliche Zustand des Wäschepostens durch direkte oder indirekte Meßeinrichtungen erfaßt und berücksichtigt wird. So ist z.B. neben dem Verschmutzungsgrad des Waschgutes vor allem ihre Saugfähigkeit eine wesentliche Eigenschaft, die für den erforderlichen Wasser- und Waschmitteleinsatz beachtet werden muß.In washing machines of this type, the washing process usually continues a fixed program, which with regard to the use of water, time of mechanical action, temperature and detergent dosage is geared towards maximum requirements. However, it would be desirable to carry out a washing program in which the actual Condition of the batch of laundry is detected and taken into account by direct or indirect measuring devices. For example, in addition to the degree of soiling of the Items to be washed, especially their absorbency, an essential property for the required water and detergent use must be observed.

Es sind bereits eine Reihe von Vorschlägen gemacht worden, bei denen die vorgenannten Kriterien durch Meßeinrichtungen festgestellt werden, um wasser- und waschmittelsparend zu waschen.A number of proposals have already been made in which the The aforementioned criteria are determined by measuring devices in order to wash in a water- and detergent-saving manner.

So ist z.B. aus der DE-OS 29 20 492 ein Verfahren bekannt geworden, bei dem zunächst die Masse der Wäschefüllung direkt über Meßfühler ermittelt und aus diesem Wert das vorzugebene Niveau berechnet wird, um dann dasFor example, from DE-OS 29 20 492 a method has become known in which firstly determines the mass of the laundry filling directly via a measuring probe and from this value the specified level is calculated, in order to then use the

Dieses Verfahren erfordert ein aufwendiges Meßwert-Erfassungssystem. to record the actual level in the wash tub and based on it select the following washing process criteria based on the measured values obtained in this way. This method requires a complex data acquisition system.

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile beim Stand der Technik so weit wie möglich zu beseitigen und eine Waschprogrammoptimierung durch volle Ausnutzung der durch die Sensortechnik gegebenen Möglichkeiten zu erreichen, die wesentlich über das bei Waschmaschinen dieser Art bisher Übliche liegen soll.The invention is based on the object of addressing the disadvantages of the prior art Eliminate technology as much as possible and optimize the washing program by making full use of the possibilities provided by sensor technology to achieve, which should be significantly above what has been customary in washing machines of this type.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruches 1 zu entnehmen.The solution to this problem according to the invention is the characterizing part of claim 1 can be found.

Zweckmäßige Weiterbildungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Appropriate developments of the subject matter of the invention are in the Subclaims indicated.

Die von der Meßeinrichtung erfaßten wasserniveauabhangigen Meßwerte und die Anzahl der über einen Zähler registrierten Waschbottich-Wassernachfüllungen werden als Hinweisgröße für die Saugfähigkeit des Waschgutes ausgenutzt. Daraus werden dann im Rechner für eine in der Programmsteuerung eingegebene bestimmte Wäscheart die optimalsten Waschprogrammparameter eine Waschmittelzugabe, Spülwassermenge, Unwuchtgrenze, Waschmechanik, Waschtrommeldrehzahl, Schleuderdurchlaufzeit u.a. für den folgenden Wasch- und Schleudergang bestimmt.The water level-dependent measured values and recorded by the measuring device the number of wash tub water refills registered via a counter are used as an indicator for the absorbency of the items to be washed exploited. From this, the most optimal washing program parameters are then generated in the computer for a certain type of laundry entered in the program control Adding detergent, amount of rinse water, unbalance limit, washing mechanics, washing drum speed, spin cycle time, etc. for the determined for the following wash and spin cycle.

Sensor 2 vorgesehen, dessen Meßleitung 3 am Ablauf 4 des Waschbottichs angeschlossen ist. Im Ablauf 4 ist eine übliche Entleerungspumpe 5 angeordnet. Der Zulauf des Frischwassers erfolgt über eine Zuleitung 6, in der sich ein Ventil 7 (Magnetventil) befindet, dessen jeweilige Offenstellungen zum Zwecke des Wasserzulaufes in den Waschbottich 1 von einem Zähler 8 (Zählelektronik) registriert und die Zählwerte an einen Rechner 9 weitergegeben werden. Die vom Niveau-Sensor 2 erfaßten Wasserniveaumeßwerte werden einem elektronischen Auswerter 10 gemeldet und gehen nach entsprechender Auswertung in den Rechner 9 ein. Im Ausgang 11 des Rechners ist eine elektronische Referenzschaltung 12 für den Auswerter 10 gelegt. Durch diese Referenzschaltung werden Störgrößen dem Auswerter 10 durch den Rechner 9 aufgeschaltet. Solche Störgrößen können sich z.B. aus der Waschtrommelbeschleunigung und der Wasser-Zulaufzeit bis zum Erreichen des vorgegebenen Sollniveaus beim ersten Einlauf ergeben. Über eine Programmeingabe 13 wird die Wäscheart (Waschgut), mit der die WäschetrommelSensor 2 is provided, the measuring line 3 of which is connected to the outlet 4 of the wash tub. A conventional drain pump 5 is arranged in the outlet 4. The fresh water is supplied via a supply line 6 in which there is a valve 7 (solenoid valve), the respective open positions of which are registered by a counter 8 (electronic counting device) for the purpose of the water supply to the washing tub 1 and the counted values are passed on to a computer 9. The measured water level values detected by the level sensor 2 are reported to an electronic evaluator 10 and are entered in the computer 9 after a corresponding evaluation. An electronic reference circuit 12 for the evaluator 10 is placed in the output 11 of the computer. By means of this reference circuit, disturbance variables are applied to the evaluator 10 by the computer 9. Such disturbance variables can result, for example, from the washing drum acceleration and the water inflow time until the predetermined target level is reached during the first run-in. Via a program input 13, the type of laundry (items to be washed) with which the laundry drum

beladen ist, ausgewählt bzw. eingegeben. 'is loaded, selected or entered. '

Die Funktionsweise der beschriebenen Anordnung ist folgende:The described arrangement works as follows:

Es wird angenommen, daß die Wäschetrommel im Waschbottich mit einem bestimmten Waschgut beladen ist und die Art dieses Waschgutes in der Programmeingabe 13 entsprechend eingegeben worden ist. Mit Starten des Waschprogrammes wird das Einlaß-Ventil 7 geöffnet und der Wassereinlauf erfolgt, bis der Schaltpunkt für das vorgegebene Sollniveau im Waschbottich erreicht ist. Nunmehr wird das Einlaß-Ventil 7 wieder geschlossen und gleichzeitig beginnt die Waschbewegung der Wäschetrommel. Durch die übliche reversierende Bewegung der Wäschetrommel wird die Wäsche mehr und mehr durch-flutet, und sie nimmt je nach Saugfähigkeit der Gewebeart des betreffenden Waschgutes Wasser auf. Dies hat zur Folge, daß der Wasserstand im Waschbottich 1 sinkt und unterhalb des Sollniveau fällt. Das Einlaß-Ventil 7 wird erneut geöffnet, um durch weiteren Wassereinlauf das vorgegebene Sollniveau im Waschbottich wieder herzustellen. Dieser Nachfüllvorgang kann sich je nach der Saugfähigkeit des Waschgutes mehrmals wiederholen. DieIt is assumed that the laundry drum in the wash tub with a certain items are loaded and the type of items to be washed in the program input 13 has been entered accordingly. When the washing program starts, the inlet valve 7 is opened and the water inlet takes place until the switching point for the specified target level in the wash tub is reached. Now the inlet valve 7 is closed again and at the same time the washing movement of the washing drum begins. Due to the usual reversing movement of the laundry drum, the laundry becomes more and more through-floods, and it increases depending on the absorbency of the tissue type of the concerned Wash good water on. This has the consequence that the water level in the wash tub 1 drops and falls below the target level. The inlet valve 7 is opened again in order to restore the specified target level in the wash tub by further running in the water. This refilling process can repeat several times depending on the absorbency of the laundry. the
