Abstract

In this process for controlling the spin programme of a washing machine, a microcomputer control having an unbalance recognition device, a speed-regulating device and a timing device is used. In a run-up phase predetermined in the spin programme, the unbalance and the time required for the run-up phase are measured. By comparison with stored reference values, the further speed trend of the spinning operation is then determined.

Description

Verfahren zur Steuerung des SchleuderprogrammsProcedure for controlling the spin program

einer Waschmaschine Die Erfindung bezieht sich auf ein Verfahren zur Steuerung des Schleuderprogramms einer Waschmaschine unter Verwendung einer Mikrocomputer-Steuerung, einer Unwuchterkennungseinrichtung sowie einer Drehzahlregelungseinrichtung für den Antriebsmotor der Wäschetrommel und auf eine Anordnung zur Durchführung dieses Verfahrens.a washing machine The invention relates to a method for Controlling the spin program of a washing machine using a microcomputer controller, an imbalance detection device and a speed control device for the drive motor of the laundry drum and an arrangement for performing this Procedure.

Aus der DE-OS 26 20 464 ist ein Verfahren zur Steuerung des Schleuderprogramms einer Waschmaschine bekannt, bei dem eine Unwuchtmessung durchgeführt wird, die dann den weiteren Ablauf des Schleuderprogramms bestimmt. Hierbei werden die Schwankungen der Stromaufnahme oder der Drehzahl des Antriebsmotors als Indiz für eine eventuell vorliegende Unwucht ausgewertet.From DE-OS 26 20 464 a method for controlling the spin program is a washing machine known in which an unbalance measurement is carried out, the then determines the further sequence of the spin program. Here are the fluctuations the power consumption or the speed of the drive motor as an indication of a possibly present imbalance evaluated.

Ein Nachteil des vorbeschriebenen Meßverfahrens besteht jedoch darin, daß die Unwuchterfassung nur sehr ungenau erfolgt und nicht bei allen möglichen Betriebsbedingungen einen optimalen Schleuderablauf gewährleistet.However, a disadvantage of the above-described measuring method is that that the unbalance detection takes place only very imprecisely and not with all possible Operating conditions guarantee an optimal spin process.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art und eine Anordnung zur Durchführung des Verfahrens zu schaffen, bei der eine ziemlich genaue Erfassung von Unwuchtzuständen während des Schleuderbetriebs möglich ist, wobei der weitere Schleuderablauf in Abhängigkeit von den gemessenen Augenblickswerten optimal gesteuert werden kann.The invention is therefore based on the object of a method of to create the type mentioned at the beginning and an arrangement for carrying out the method, in which a fairly accurate detection of unbalance conditions during the spin operation is possible, the further spin cycle depending on the measured Instantaneous values can be optimally controlled.

Die Lösung dieser Aufgabe wird durch die im Hauptanspruch gekennzeichneten Merkmale erreicht. Weitere Merkmale und Ausgestaltungen der Erfindung ergeben sich aus den nachgestellten Unteransprüchen.The solution to this problem is characterized by that in the main claim Features achieved. Further features and configurations of the invention result from the subsequent subclaims.

Durch das erfindungsgemäße Verfahren und die entsprechende Anordnung zur Durchführung des Verfahrens läßt sich in einer Waschmaschine mit einer Mikrocomputer-Steuerung das Schleuderverfahren in Abhängigkeit von einer eventuell vorliegenden Unwucht optimal durchführen. Unterschiedliche Beladungsmengen als auch unterschiedlich vorliegende Versorgungsspannungen werden erfasst und bei der weiteren Drehzahlsteuerung des Antriebsmotors berücksichtigt.By the method according to the invention and the corresponding arrangement to carry out the method can be in a washing machine with a microcomputer control the centrifugal process depending on any imbalance that may be present perform optimally. Different loads as well as different ones Supply voltages are recorded and during the further speed control of the Drive motor taken into account.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt. Es zeigen: Fig. 1 ein Drehzahl/Zeitdiagramm der Wäschetrommel einer haushaltsüblichen Waschmaschine, Fig. 2 ein Blockschaltbild für die Drehzahlsteuerung des Antriebsmotors der Waschmaschine mit den wesentlichen, zur Erläuterung der Erfindung notwendigen Schaltungsbausteinen einer Programmsteuerung.An embodiment of the invention is shown schematically in the drawings shown. 1 shows a speed / time diagram of the laundry drum of a household washing machine, Fig. 2 is a block diagram for the speed control of the drive motor of the washing machine with the essentials to explain the invention necessary circuit components of a program control.

In der Figur 1 ist der Drehzahlverlauf einer Waschmaschine zu Beginn des Schleuderprogramms dargestellt. Die das Schleuderverfahren beeinflussenden überwachungseinrichtungen ergeben sich aus dem Blockschaltbild nach der Figur 2.In FIG. 1, the speed curve of a washing machine is at the beginning of the spin program. The monitoring devices influencing the centrifugal process result from the block diagram according to FIG. 2.

tiblicherweise wird die Wäschetrommel der Waschmaschine von der Waschgangsdrehzahl nu (50 U min-l) auf eine Anliegedrehzahl nA (95 U min 1) gebracht. Im Anliegedrehzahlbereich (75-95 U min 1) wird nun durch eine Unwuchterkennungseinrichtung U das Drehzahl- oder Stromaufnahmeverhalten des Antriebsmotors während dieser Phase ausgewertet und einem Mikrocomputer MC zugeführt.Typically, the washing machine's drum is controlled by the wash cycle speed nu (50 rpm) brought to an applied speed nA (95 rpm). In the applied speed range (75-95 U min 1) an unbalance detection device U is used to determine the speed or the current consumption behavior of the drive motor is evaluated during this phase and supplied to a microcomputer MC.

Nachdem die Enddrehzahl des Unwuchterkennungsbereiches nach der Zeit tA erreicht ist, wird durch die Drehzahlsteuereinrichtung D der Antriebsmotor M der Wäschetrommel mit einem vorbestimmten Stromflußwinkel (z.B. 900) angesteuert. Dadurch wird die Wäschetrommel auf die höhere Drehzahl nT gebracht. Wie die Drehzahlkurve n1 zeigt, benötigt der Motor für die Beschleunigung der Wäschetrommel auf den höheren Wert nT die Zeit t1-tA. Dieser Zeitwert wird von einer Zeitmeßstufe T erfaßt und dem Mikrocomputer MC zugeführt. Weiterhin wird im Verlaufe des Hochfahrens der augenblickliche Wert der Versorgungsspannung durch die Spannungsmeßstufe V ermittelt und auch dieser Meßwert wird dem Mikrocomputer zugeführt.After the final speed of the imbalance detection area after the time tA is reached, the drive motor M the laundry drum is controlled with a predetermined current flow angle (e.g. 900). This brings the laundry drum to the higher speed nT. Like the speed curve n1 shows the motor needed to accelerate the laundry drum to the higher one Value nT the time t1-tA. This time value is recorded by a time measuring stage T and supplied to the microcomputer MC. Furthermore, in the course of startup, the current one becomes The value of the supply voltage is determined by the voltage measuring stage V and this too The measured value is fed to the microcomputer.

Wie nun die Drehzahlkurve n2 ausweist, wird hier die vorgegegebene höhere Drehzahl nT erst später (t2) erreicht. Die Ursache kann darin bestehen, daß sich zum Zeitpunkt des Schleudervorgangs eine höhere als die übliche Beladungsmenge in der Trommel befand, daß die Netzspannung niedriger als üblich war oder es lagen gar beide Zustandsbedingungen zusammen vor. Diese unterschiedlichen Parameter werden nun aber erkannt und ausgewertet.As the speed curve n2 now shows, the specified one is used here higher speed nT only reached later (t2). The cause may be that at the time of the spinning process a higher than the usual load Inside the drum found the line voltage was or was lower than usual even present both conditions together. These different parameters will be but now recognized and evaluated.

In einem Speicher des Micorcomputers MC ist eine empirisch ermittelte Referenzwerttabelle abgelegt, in der die das Schleuderverfahren beeinflussenden Daten wie Beladungsmenge, Versorgungsspannung und vorher ermittelter Unwuchtwert berücksichtigt sind. Zu Beginn des Schleuderprogramms werden nun wie vorbeschrieben dem Microcomputer MC die entsprechenden Meßwerte des augenblicklichen Schleuderprogramms zugeführt. Innerhalb des Microcomputers MC werden dann die aufgenommenen Daten mit denen der Referenzwerttabelle verglichen und entsprechend ihrer unterschiedlichen Auswirkungen ausgewertet. Das Ergebnis der Auswertung bestimmt dann den weiteren Verlauf des Schleuderverfahrens. So kann bei geringer Unwucht sofort weiter auf die Endschleuderdrehzahl hochgefahren werden, bei einem mittleren Unwuchtwert nur eine reduzierte Drehzahl angefahren werden oder es wird bei einem unzulässigen Unwuchtwert in eine neue Verteilungsphase zurückgeschaltet und der Schleuderhochlauf von neuem gestartet. Andererseits erlauben die heute einsetzbaren Microcomputer-Steuerungen eiecbeliebige Anpassung der Schleuderdrehzahl an die unterschiedlichen Augenblickszustände, wie sie im üblichen Schleuderprogramm einer Waschmaschine auftreten können.In a memory of the microcomputer MC is an empirically determined Reference value table stored in which those influencing the centrifugal process Data such as load quantity, supply voltage and previously determined unbalance value are taken into account. At the beginning of the spin program, the following are now described the microcomputer MC the corresponding measured values of the current spin program fed. The recorded data are then included within the microcomputer MC compared to those of the reference value table and according to their different Impact evaluated. The result of the evaluation then determines the further one Course of the centrifugal process. This means that if there is a slight imbalance, you can continue to open immediately the final spin speed can be increased, with a medium imbalance value only a reduced speed can be approached or if there is an impermissible imbalance value switched back to a new distribution phase and the spin ramp-up again started. On the other hand, the microcomputer controls that can be used today allow Any adjustment of the spin speed to the different momentary conditions, as they can occur in the normal spin program of a washing machine.

Durch das erfindungsgemäße Verfahren wird jedenfalls eine zuverlässige, genaue und sichere Steuerung des Schleuderprogramms ermöglicht.In any case, the method according to the invention provides a reliable, enables precise and safe control of the spin program.
