Abstract

Registering programme control parameters for household washing machines using revolution speed electronics a reversibly driven drum, a water supply system regulated irrespective of operational pressure, and a level control system. At the start of the programme and when the drum is stationary and has been loaded, the time span (t1) until the working level (NA) has been reached for the first time is measured. After the reaching of the working level (Na), the first laundry absorption time (tS1) until the level is lowered to the reconnection level (NE) is measured. For the now reversing drum, the process involves measuring the directly succeeding second absorption time (tS2). Temporal difference between the second and the first times (tS2-tS1) is determined. Number of all replenishing processes from the reconnection level to the working level are registered. ADVANTAGE - Machine automatically determines whether a programme is required for small or large volumes of washing while taking into account the type of washing.

Description

Die Erfindung betrifft ein Verfahren zur Ermittlung von Programmsteuerungs-Parametern für Haushalt-Waschmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for determining Program control parameters for household washing machines after Preamble of claim 1.

Am Markt erhältliche Haushalt-Waschmaschinen der in Rede stehenden Art besitzen durchwegs eine gesonderte Benutzertaste für kleinere Wäschemengen. Diese Taste ist allgemein unter der Bezeichnung "1/2 Taste" bekannt und bewirkt einen speziellen, für kleine Füllmengen optimierten Wasch-, Spül- und Schleuder-Programmablauf. (AEG Prospekt 1991 "Waschautomaten,Trockner, Schleudern").Household washing machines of the type in question available on the market consistently have a separate user button for smaller ones Lots of laundry. This button is commonly called "1/2 button" known and causes a special, for small amounts optimized washing, rinsing and spinning program sequence. (AEG brochure 1991 "washing machines, dryers, spinners").

Vergißt nun der Benutzer das Betätigen der "1/2 Taste" wird zwangsläufig mit unnötig viel Wasser und mit zu hohem Energieverbrauch eine kleine Wäschemenge behandelt.If the user now forgets to press the "1/2 button", it is inevitable with unnecessarily much water and with too high energy consumption a small one Amount of laundry treated.

Der Erfindung liegt die Aufgabe zugrunde, wäschespezifische Kenngrößen zu erfassen, mit deren Hilfe das Gerät selbsttätig, d. h. ohne Benutzerführung erkennt, ob ein Arbeitsprogramm für kleine oder große Wäschemengen erforderlich ist und zugleich die Wäscheart mitberücksichtigt.The invention has for its object, laundry-specific parameters to detect, with the help of which the device automatically, d. H. without User guidance recognizes whether a work program for small or large Amount of laundry is required and at the same time the type of laundry also taken into account.

Diese Aufgabe gemäß der Erfindung wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.This object according to the invention is characterized by the Features of claim 1 solved. Further advantageous configurations the invention can be found in the subclaims.

Die durch das erfindungsgemäße Verfahren erzielbaren Vorteile ergeben sich bereits teilweise aus der Aufgabenstellung. Es sind dies in erster Linie Wasser-und Energieeinsparungen. Als weiterer Vorteil ist anzusehen, daß ein Entfall der "1/2 Taste" ermöglicht wird. Hieraus resultiert ein erhöhter Bedienungskomfort des Gerätes.The advantages which can be achieved by the method according to the invention result  already partially out of the task. They are first Line water and energy savings. Another advantage is to see that the omission of the "1/2 button" is made possible. Out of this this results in an increased ease of use of the device.

Wasch- und Schleuderprogramme werden jeder Wäschemenge und Wäscheart optimal angepaßt. Die Restfeuchte der ausgeschleuderten Wäsche ist immer konstant.Washing and spin programs are available for all laundry quantities and laundry types optimally adapted. The residual moisture of the spun laundry is always constant.

Das Verfahren wird nachfolgend anhand eines Diagramms beschrieben. Die dargestellte Kurve veranschaulicht das geregelte Wasser- oder Laugenniveau N der Wäschetrommel in Abhängigkeit von der Wasserzulaufzeit bzw. der Wäschesaugzeit ts.The procedure is described below using a diagram. The curve shown illustrates the regulated water or alkali level N of the laundry drum as a function of the water intake time or the laundry suction time t s .

Innerhalb der Zeitspanne t1 (min) werde eine stillstehende, mit trockener Wäsche beladene Trommel bis zum Abschalten eines Druckwächters erstmals auf das Arbeitsniveau NA befüllt. Da die Zulaufgeschwindigkeit Q (Liter pro Minute) mengengeregelt und damit unabhängig vom Wasserleitungsdruck konstant ist, bestimmt besagte Zeitspanne t1 das Maß für die zum Programmbeginn in der Trommel befindliche erstmalige Wassermenge (t1 x Q = Wassermenge in Litern). Die Zulaufgeschwindigkeit Q ist herstellerseits durch den Einsatz genau kalibrierter Durchflußmengenregler vorgegeben. Das Waschgut wird nun je nach Menge und wäscheartspezifischer Saugfähigkeit innerhalb einer bestimmten Zeitspanne den Wasserstand erstmals vom Arbeitsniveau NA auf das Wiedereinschaltniveau NE des Druckwächters absenken. Dieser Vorgang spielt sich innerhalb der Zeitspanne tS1, der ersten Wäschesaugzeit ab. Die Länge der Zeitspanne tS1 stellt bei stillstehender Trommel ein Maß für die Wäschesaugfähigkeit und somit für die Wäscheart dar.Within the time period t 1 (min) will a stationary charged with dry laundry drum up to the switching off of a pressure switch for the first time filled to the operating level N A. Since the feed rate Q (liters per minute) is quantity-controlled and therefore constant regardless of the water pipe pressure, said time period t 1 determines the measure of the first amount of water in the drum at the start of the program (t 1 x Q = amount of water in liters). The inlet speed Q is predetermined by the manufacturer through the use of precisely calibrated flow rate controllers. Depending on the quantity and the type of laundry-specific absorbency, the laundry will lower the water level for the first time from working level N A to the restart level N E of the pressure switch. This process takes place within the time period t S1 , the first laundry suction time. The length of the time period t S1 is a measure of the laundry absorbency and thus the type of laundry when the drum is at a standstill.

Anschließend wird innerhalb der Zeitspanne tK, der Nachfüllzeit wiederum bis zum Arbeitsniveau NA nachgefüllt. Ein erneutes Absinken auf das Wiedereinschaltniveau NE erfolgt innerhalb der Zeitspanne tS2, der zweiten Wäschesaugzeit, wobei nun die Zeitspanne tS2 und die nachfolgenden Zeitspannen tS3 bis tS gegenüber der ersten Wäschesaugzeit tS1 mit zunehmender Wäschesättigung immer länger währen. Die Nachfüllzeiten tK sind konstant und werden von der Schaltdifferenz des Druckwächters bestimmt. Das Nachsaugen und das Regelspiel des Druckwächters dauern solange an bis die Wäsche mit Lauge gesättigt ist und das Maß ihrer gebundenen Flotte erreicht hat. Die Anzahl der Nachtaktungen oder die Gesamtzahl der Nachfüllzeiten tK sind ein Kriterium für die Größe der eingefüllten Wäschemenge.The refill time is then refilled up to the working level N A within the time period t K. Again falls to the reclosure level N E is within the time period t S2, the second Wäschesaugzeit, wherein the time period is now t S2 and the subsequent periods T S3 to t S with respect to the first Wäschesaugzeit t S1 with increasing wash saturation always longer During. The refill times t K are constant and are determined by the switching differential of the pressure switch. The suction and control play of the pressure switch continue until the laundry is saturated with lye and has reached the level of its bound liquor. The number of night cycles or the total number of refill times t K are a criterion for the size of the amount of laundry that is filled.

Die Wäschemenge kann auch bei reversierender Trommel aus der Zeitdifferenz zwischen der zweiten Wäschesaugzeit tS2 und der ersten Wäschesaugzeit tS1 ermittelt werden (ΔtS21=tS2-tS1).The amount of laundry can also be determined in the case of a reversing drum from the time difference between the second laundry suction time t S2 and the first laundry suction time t S1 (Δt S21 = t S2 -t S1 ).

Mit Hilfe der zu Programmbeginn erfaßten und bereits erwähnten wäschespezifischen Parametern:With the help of those recorded at the beginning of the program and already mentioned laundry-specific parameters:

Erstmalig zulaufende Wassermenge aufgrund der Zeitspanne t1
Wäscheart aufgrund der ersten Wäschesaugzeit tS1 bei stillstehender Trommel,
Wäschemenge aufgrund der Anzahl der Nachfüllvorgänge (bzw. Gesamtzahl der Nachfüllzeiten tK oder Gesamtzahl der Wäschesaugzeiten tSn) und alternativ
Wäschemenge aufgrund der zeitlichen Differenz ΔtS21 bei reversierender Trommel
wird nun die erforderliche Wassermenge und die Anzahl der Waschgänge für den Programmabschnitt "Waschen", die erforderliche Wassermenge und die Anzahl der Spülgänge für den Programmabschnitt "Spülen" ermittelt und das Drehzahlprofil (stufenweise Veränderung und zeitliche Vorgabe der Trommelumdrehungszahlen) im Programmabschnitt "Schleudern" dem jeweiligen Waschgut nach Art und Menge optimal angepaßt. Solcherart gesteuerte Schleudergänge erbringen eine konstante Wäscherestfeuchte (Prozent).Amount of water flowing in for the first time due to the time period t 1
Type of laundry due to the first laundry suction time t S1 with the drum at a standstill,
Amount of laundry based on the number of refill processes (or total number of refill times t K or total number of laundry suction times t Sn ) and alternatively
Amount of laundry due to the time difference Δt S21 with reversing drum
the required amount of water and the number of wash cycles for the program section "washing", the required amount of water and the number of rinse cycles for the program section "rinsing" are now determined and the speed profile (gradual change and timing of the drum revolutions) in the program section "spin" each item to be optimally adjusted according to type and quantity. Spin cycles controlled in this way provide a constant residual moisture in the laundry (percent).

Arbeitsprogramme, bei welchen selbsttätig Wassermengen und Waschprogrammabläufe bestimmt werden, steuert man mit sogenannter "Fuzzy"-Control bzw. "Fuzzy"-Logic.Work programs in which water quantities and Wash program sequences are determined, controlled with so-called "Fuzzy" control or "Fuzzy" logic.
