Abstract

A household washing machine dispenses detergent automatically in the appropriate amount.

Description

Umweltbewußtsein, Wassermangel, Energiekosten und zunehmende von Waschmittelresten hervorgerufene Allergien verlangen nach einer technologisch weiterentwickelten Waschmaschine. Bisherige Neuentwick­ lungen von Waschmaschinen konzentrieren sich auf eine Reduzierung von Wasser- und Energieverbrauch, was zwar die Betriebskosten senkt, aber der Umwelt nur sekundär zugute kommt, da die Hauptbelastung durch chemische Rückstände nicht signifikant reduziert wird.Environmental awareness, water shortages, energy costs and increasing Allergies caused by detergent residues require one technologically advanced washing machine. Previous new developments lungs of washing machines focus on a reduction of water and energy consumption, which reduces operating costs but the environment benefits only secondarily, since the main pollution is not significantly reduced by chemical residues.

Der Waschprozeß wird maßgebend durch folgende Parameter beeinflußt: Grad und Art der Verschmutzung der Wäsche einerseits, sowie Waschmittelkonzentration, mechanische Energie, Temperatur und Zeit­ dauer andrerseits. Bisherige Waschmaschinen registrieren weder Ver­ schmutzungsgrad noch Waschmittelwirksamkeit, so daß in der Regel das Waschmittel in einer erheblichen Überdosis zugeführt wird.The washing process is significantly influenced by the following parameters: Degree and type of soiling on the one hand, as well as Detergent concentration, mechanical energy, temperature and time duration on the other hand. Previous washing machines do not register Ver degree of soiling still detergent effectiveness, so that usually Detergent is supplied in a significant overdose.

Der Erfindung liegt die Aufgabe zugrunde, beim Waschen nur so viel Waschmittel (komponentenweise) hinzuzudosieren, wie tatsächlich erfor­ derlich ist, und den Waschprozeß ökologisch zu optimieren.The invention is based, so much only when washing Add detergent (component by component) as actually required is necessary, and to optimize the washing process ecologically.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß zunächst auf­ grund gemessener Wäschemenge und Wasseraufnahmefähigkeit der Wä­ sche eine Mindestmenge des (Flüssig-)Waschmittels zudosiert wird, dann der Waschprozeß beginnt und anhand dessen Ablaufs (Veränderung der Konzentration der Waschlaugenkomponenten und der Verschmutzung) entschieden wird, ob und wieviel Waschmittel nachdo­ siert wird, ob die Wassertemperatur innerhalb der vorgegebenen Gren­ zen verändert werden soll oder ob es sinnvoller ist, die Waschlauge gänzlich zu erneuern.The object is achieved in that initially on due to measured amount of laundry and water absorption capacity of the laundry a minimum amount of (liquid) detergent is added, then the washing process begins and based on its sequence (Change in the concentration of the detergent components and the Pollution) it is decided whether and how much detergent afterdo It is determined whether the water temperature is within the specified limits zen should be changed or whether it makes more sense, the wash liquor to renew completely.

Die zur Regelung bzw. Steuerung des Waschprozesses erforderliche Sensorik wird gleichzeitig dazu verwendet, die notwendige Art der Spülung zu optimieren. Durch Ermittlung der Waschmittelrückstände im Spülwasser und der individuellen Vorgabe (z. B. Allergieempfindlichkeit, hautberührende Wäsche etc.) wird auch die Anzahl der Spülgänge und die dabei verwendete Wassermenge durch die in der Software abgelegte Intelligenz bestimmt.The necessary to regulate or control the washing process Sensor technology is used at the same time, the necessary type of To optimize flushing. By determining the detergent residues in the Rinsing water and individual requirements (e.g. allergy sensitivity, skin-touching laundry etc.) will also include the number of rinses and the amount of water used by the amount stored in the software Intelligence determines.
