The solution to this problem is characterized by that in the main claim Features achieved. Further features and configurations the invention result from the following subclaim and from the description.
Durch Herabsetzung der Anzahl direkter Leitungsverbindungen wird eine übersichtliche Steuerungsanordnung in dem Gerät erhalten, die sich zudem noch universell für die verschiedensten Gerätegruppen einsetzen läßt. Weiterhin sind mit diesem Mikrocomputersteuerungssystem sämtliche Anforderungen erfüllbar, die man heute an eine derartige Gerätesteuerung stellen kann.By reducing the number of direct line connections, one Clear control arrangement in the device, which is also universal can be used for a wide variety of equipment groups. Continue with this Microcomputer control system can meet all the requirements that one has today such a device control can provide.
Darüber hinaus ist es ein weiterer Vorteil, daß zusätzliche Vorkehrungen für die Status-Rettung oder Abspeicherung des Programmzustandes bei Netzausfall nicht erforderlich sind.In addition, there is another advantage to having additional precautions for saving the status or saving the program status in the event of a power failure are not required.
Ein Ausführungsbeispiel der Erfindung wird in der Zeichnung schematisch dargestellt und nachfolgend näher erläutert.An embodiment of the invention is shown schematically in the drawing and explained in more detail below.
Das Blockschaltbild zeigt eine Programmsteuerung für eine Waschmaschine, Kernstück der dargestellten Steuerungskonzeption ist die zentrale Steuereinheit 1, die einen Mikrocomputer enthält.The block diagram shows a program control for a washing machine, The core of the control concept shown is the central control unit 1, which includes a microcomputer.
Die zentrale Steuereinheit 1 erhält ihre Programmsteuerungsbefehle hinsichtlich Programmart, Temperatur, Drehzahl, Waschmitteldosierung und eventueller Zusatzfunktionen von der Eingabeeinheit 2. Die Eingabeeinheit 2 kann durch eine Kurzhubtastatur, Sensortastatur oder mechanische Schalter realisiert sein.The central control unit 1 receives its program control commands with regard to the type of program, temperature, speed, detergent dosage and any Additional functions of the input unit 2. The input unit 2 can by a Short-stroke keyboard, sensor keyboard or mechanical switches can be implemented.
Der zentralen Steuereinheit 1 wird eine motorbetriebene Wasserweiche 3 direkt zugeordnet. Hierbei kann der Synchronmotor 4 mit seinem Lagedetektor 5 auf der gleichen Platine der zentralen Steuere inheit 1 sitzen. Durch diese Maßnahme läßt sich der Lagedetektor 5 der Wasserweiche 3 für die Programmzustandsanzeige und auch für die Status-Rettung bei unvorhergesehenem Netzspannungsausfall ausnutzen.The central control unit 1 is a motorized water switch 3 directly assigned. The synchronous motor 4 with its position detector 5 sit on the same circuit board of the central control unit 1. By this measure the position detector 5 of the water switch 3 for the program status display and can also be used to rescue the status in the event of an unforeseen mains voltage failure.
Über einen Bowdenzug kann in bekannter Weis vom Synchronmotor 4 der Wasserweiche 3 die en.Lernt am Einspülkasten 6 liegende Wasserdüse programmabhängig gesteuert werden.Via a Bowden cable, in a known manner, the synchronous motor 4 can Water switch 3 learns the water nozzle on the dispenser drawer 6 depending on the program being controlled.
Von der zentralen Steuereinheit 1 wird die Anzeigeeinrichtung 7 der Maschine angesteuert. An der Anzeigeeinrichtung 7 können die Restzeit des Programms, die Laugentemperatur, die aktuelle Drehzahl, der Pro~rammzustand oder ein auftretender Betriebsfehler angezeigt werden.From the central control unit 1, the display device 7 is the Machine controlled. On the display device 7, the remaining time of the program, the suds temperature, the current speed, the program status or an occurring one Operating errors are displayed.
Über eine serielle Schnittstelle 8 ist die zentrale Steuereinheit 1 mit einer weiteren Steuereinneit 9 verbunden. Diese enthält ebenfalls ein t#ikrocomputersystern z.B. mit einem Standard-Mikrocomputer, der anwendungsorientiert programmiert ist.The central control unit is via a serial interface 8 1 connected to a further control unit 9. This also contains a microcomputer system e.g. with a standard microcomputer that is programmed in an application-oriented manner.
Diese Steuereinheit 9 übernimmt im wesentlichen die Ansteuerung der Verbraucher und die Auswertung der Sensor-Signale der verschiedensten Zustandsüberwachungen. So wird die Drehzahlregelung für den Antriebsmotor 10 der Waschmaschine, die Reversierung und die Unwuchterfassung von der Steuereinheit 9 durchgeführt. Weiterhin werden entsprechend der Programmfolge die Verbraucher wie Heizung, Laugenpumpe, Magnetventil, Dosierpumpe, und Türverriegelung über entsprechende Leistungsschalter (Relais, Triacs) angesteuert. Die an unterschiedlichen Stellen im Gerät befindlichen Sensoren für die Temperatur, den Wasserstand, das Wäschegewicht und die Laugenverschmutzung geben ihre Signale direkt an die Steuereinheit 9.This control unit 9 essentially takes over the control of the Consumers and the evaluation of the sensor signals of the various condition monitoring. So the speed control for the drive motor 10 of the washing machine, the reversing and the imbalance detection is carried out by the control unit 9. Continue to be according to the program sequence the consumers such as heating, Drain pump, Solenoid valve, dosing pump and door lock via appropriate circuit breakers (Relays, triacs) activated. Those located in different places in the device Sensors for temperature, water level, laundry weight and lye contamination send their signals directly to the control unit 9.
Eine besonders vorteilhafte Ausbildung wird erhalten, wenn man die Steuereinheit 9 mit den entsprechenden Leistungsschaltern direkt dem anzusteuernden Verbraucher -wie hier dem Antriebsmotor - innerhalb des Gerätes örtlich zuordnet. Dadurch wird insgesamt ein übersichtlicher und einfacher Verdrahtungsaufbau erzielt.A particularly advantageous training is obtained when the Control unit 9 with the corresponding circuit breakers directly to the one to be controlled Consumers - as here the drive motor - assigned locally within the device. As a result, a clear and simple wiring structure is achieved overall.
