Abstract

Washing machine has a program control with functional control through the program steps, has a time component coupled to each step which is ended by the program control on completion of the program step. USE/ADVANTAGE - The system is for washing machine, and the like, where the program has a number of steps for the various functions within the whole program. The operation allows the overall program to compensate for faults and worse case situations to bring the program step timining into line with the actual situation.

Description

Die Erfindung betrifft eine Waschmaschine oder dgl. mit einer Programmablaufsteuerung, durch die Programmschritte eines Programmablaufs funktionsabhängig steuerbar sind.The invention relates to a washing machine or the like. With a Program sequence control, through the program steps of a program sequence are controllable depending on the function.

Bei bekannten Waschmaschinen werden beispielsweise einzelne Programmschritte eines Programmablaufs zeitabhängig gesteuert, d. h. die Dauer eines Programmschrittes ist bei einer elektromechanischen Programmablaufsteuerung von deren Schrittschaltwerk vorgegeben. Dagegen ist bei einer funktions- bzw. prozeßabhängigen Steuerung eines Programmschrittes dieser dann beendet, wenn beispielsweise eine bestimmte Temperatur, Drehzahl oder ein bestimmtes Wasserniveau erreicht worden ist. Eine funktions- bzw. prozeßabhängige Steuerung eines Programmschrittes hat nun aber den Nachteil, daß im Fehler- oder im sogenannten "worst-case-Fall" die funktions- bzw. prozeßabhängige Zeitspanne zu lang ist oder sogar unendlich werden kann. Dies kann zu einer Schädigung des Waschgutes führen oder im Extremfall sogar eine Gefahr für die Waschmaschine darstellen.In known washing machines, for example, individual program steps of a program run controlled time-dependent, d. H. the duration of a The program step is for an electromechanical program sequence control specified by their stepper. In contrast, with a functional or process-dependent control of a program step this ends when for example a certain temperature, speed or a certain one Water level has been reached. A function or process dependent Controlling a program step has the disadvantage, however, that in the error or in the so-called "worst case" the function or process dependent Period is too long or can even become infinite. This can lead to a Damage to the items to be washed or, in extreme cases, even a danger to them Show washing machine.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den aufgezeigten Nachteil zu vermeiden und eine weitere Optimierung des Programmablaufs zu erreichen.The invention is therefore based on the object to the disadvantage shown avoid and achieve further optimization of the program flow.

Die Lösung dieser Aufgabe gemäß der Erfindung besteht darin, daß den Programmschritten eine Zeit überlagert ist, nach deren Ablauf der betreffende Programmschritt durch die Programmablaufsteuerung beendet wird bzw. daß die Programmablaufsteuerung zeitabhängig gesteuerte Schaltschritte aufweist, die den funktionsabhängig gesteuerten Programmschritten überlagert sind derart, daß nach Ablauf einer bestimmten Zeitdauer durch diese Schaltschritte eine Beendigung der funktionsabhängig gesteuerten Programmschritte herbeigeführt wird. Durch diese Maßnahme wird erreicht, daß beispielsweise bei einer zu langen Aufheizzeit für die Waschflotte (Thermostat ist falsch eingestellt oder defekt) der betreffende Programmschritt unabhängig von der thermischen Funktion automatisch vom Schrittschaltwerk der Programmablaufsteuerung zeitabhängig beendet wird und damit unter Umständen eine Schädigung des Waschgutes oder der Waschmaschine verhindert bzw. vorgebeugt wird.The solution to this problem according to the invention is that Program steps a time is superimposed, after which the relevant one Program step is ended by the program sequence control or that the Program sequence control has time-controlled switching steps that the function-controlled program steps are superimposed in such a way that after a certain period of time through these switching steps Function-controlled program steps ended becomes. This measure ensures that, for example, at a too long heating-up time for the wash liquor (thermostat is wrong set or defective) the relevant program step regardless of  the thermal function automatically from the step switch of the Program sequence control is ended time-dependent and thus under Damage to the laundry or the washing machine is prevented or prevented.

Bei dem Ausführungsbeispiel gemäß der Schaltskizze ist mit 1 ein Kupplungsmagnet, mit 2 ein Timermotor und mit 3 ein Thermostat mit Kontakt 4 bezeichnet, wobei der Timermotor den Kupplungsmagneten 1 überlagert ist. Im Normalfall wird ein bestimmter Programmschritt funktionsabhängig, d. h. thermisch beendet, während im anderen Fall der betreffende Programmschritt mit Hilfe des den Kupplungsmagneten 1 überlagerten Timermotors 3 beendet wird.In the exemplary embodiment according to the circuit diagram, 1 denotes a clutch magnet, 2 denotes a timer motor and 3 denotes a thermostat with contact 4 , the timer motor being superimposed on the clutch magnet 1 . In the normal case, a certain program step is ended functionally, ie thermally, while in the other case the program step in question is ended with the aid of the timer motor 3 superimposed on the clutch magnet 1 .

Der gleiche Steuerungsablauf trifft auch bei niveau- oder drehzahlabhängig gesteuerten Programmschritten zu.The same control sequence also applies program steps controlled depending on level or speed.
