Abstract

Die Erfindung betrifft eine programmgesteuerte Waschmaschine (1), insbesondere eine Haushaltswaschmaschine, mit einer Programmwahleinrichtung (18) zur Anwahl von Waschprogrammen, welche verschiedenen Wäschearten zugeordnet sind, mit einem Laugenbehälter (2), in welchem eine Trommel (3) drehbar gelagert ist, mit einer Waschmitteleinspülkammer (9) mit mindestens einem Fach (11) zur Aufnahme von Waschmittel, mit einer Einrichtung (16) zur Ermittlung des Gewichts der in der Trommel (3) befindlichen Wäsche (4), und mit einer Mikroprozessor-Steuerung (MC) zur Berechnung einer vom Gewicht der Wäsche (4) abhängigen Waschmittel-Sollmenge für das jeweilige Waschprogramm. Um die Dosierung von Waschmittel für den jeweiligen Waschgang zu erleichtern, werden folgende Mittel vorgeschlagen:

  • Eine Einrichtung (17) zur Ermittlung eines Signals, welches der in das Fach (11) eingegebenen Waschmittel-Istmenge entspricht, und zur Weiterleitung des Signals an die Mikroprozessor-Steuerung (MC)
  • eine Vergleichseinrichtung in der Mikroprozessor-Steuerung (MC) zum Vergleich der Waschmittel-Istmenge und der für das jeweilige Programm berechneten Waschmittel-Sollmenge
  • eine durch die Mikroprozessor-Steuerung (MC) bei Erreichen der berechneten Waschmittel-Sollmenge aktivierbare Signaleinrichtung (20).

The invention relates to a program-controlled washing machine (1), in particular a household washing machine, with a program selection device (18) for selecting washing programs which are assigned to different types of laundry, with a tub (2) in which a drum (3) is rotatably mounted a detergent dispensing chamber (9) with at least one compartment (11) for holding detergent, with a device (16) for determining the weight of the laundry (4) in the drum (3), and with a microprocessor control (MC) for Calculation of a target detergent quantity depending on the weight of the laundry (4) for the respective washing program. In order to facilitate the dosing of detergent for the respective wash cycle, the following agents are proposed:
  • A device (17) for determining a signal which corresponds to the actual detergent quantity entered in the compartment (11) and for forwarding the signal to the microprocessor control (MC)
  • a comparison device in the microprocessor control (MC) for comparing the actual detergent quantity and the desired detergent quantity calculated for the respective program
  • a signal device (20) which can be activated by the microprocessor control (MC) when the calculated detergent target quantity is reached.
