Abstract

The washing and rinsing processes are controlled dependent upon the ascertained degree of dirtiness in the water. During the commencement phase of the washing or rinsing processes, a measurement and evaluation process is used during a specific time period to assess the degree of dirtiness in the water and then after a further specific time the measurement and evaluation process is repeated. From each of the two measurement processes a measurement value is deduced of the energy used for a determined operating section. After evaluation of these measurment values the energy-favourable evolution of the washing or rinsing processes is determined and effected. The increase in washing or rinsing water temp. occurs after a firmly predetermined or deduced time point. USE/ADVANTAGE - To automate the washing programme in a washing or dishwashing machines so that energy usage is minimal with optimal washing results.

Description

Die Erfindung betrifft eine Wasch- oder Geschirrspülmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a washing or Dishwasher according to the generic term of Claim 1.

Bei einer bekannten Waschmaschine dieser Art wird durch eine Messung im Vorwaschgang die Schmutzanreicherung im Waschwasser erfaßt. Der ermittelte Sollwert der Schmutzanreicherung wird dann zur entsprechenden automatischen Einregelung der Waschmaschine beispielsweise hinsichtlich der Waschtemperatur oder Waschdauer benutzt (DE-OS 14 35 031). Des weiteren ist ein Waschautomat bekannt, bei dem der Waschprogrammablauf über eine Messung der Trübung der Lauge automatisch entsprechend verlängert oder verkürzt wird. Weiter ist es bekannt, über die erfaßte Trübung der Lauge auf die Anzahl der erforderlichen Spülgänge zu schließen.In a known washing machine of this type is used a measurement in the prewash cycle shows the accumulation of dirt in the Wash water detected. The determined setpoint of Dirt enrichment then becomes the corresponding one automatic regulation of the washing machine for example used in terms of washing temperature or washing time (DE-OS 14 35 031). There is also a washing machine known, in which the washing program sequence via a measurement the cloudiness of the lye is automatically extended accordingly or shortened. It is also known about the captured Cloudiness of the lye to the number of required Close rinse cycles.

Aufgabe der Erfindung ist eine Automatisierung des Waschprogrammablaufs in dem Sinne anzustreben, daß der Energieverbrauch minimal wird bei optimalen Waschergebnissen.The object of the invention is to automate the To strive for the washing program in the sense that the Energy consumption becomes minimal with optimal Washing results.

Die Lösung dieser Aufgabe gemäß der Erfindung besteht nun darin, daß während der Anfangsphase des Wasch- oder Spülprozesses durch einen Meß- und Auswertevorgang der während einer gewissen Zeitspanne erreichte Verschmutzungsgrad bzw. die Trübung des Wasch- oder Spülwassers ermittelt wird, daß nach einer gewissen Zeitdauer die Temperatur des Wasch- oder Spülwassers erhöht und der vorgenannte Meß- und Auswertevorgang wiederholt wird und daß aus jedem der beiden Meßvorgänge eine auf die für einen bestimmten Vertriebsabschnitt verbrauchte Energie bezogene Meßgröße (Betriebsgröße) abgeleitet wird und daß nach Auswertung dieser Meßgrößen der energiegünstigste Ablauf des Wasch- oder Spülprozesses festgelegt und durchgeführt wird. Durch die vorgeschlagenen Maßnahmen wird ein auf den jeweiligen Wäscheposten abgestimmter Energieverbrauchs- und Funktionsergebnis optimierter Waschprogrammablauf automatisch ausgewählt und von der Programmsteuereinrichtung abgearbeitet. Zur Messung des Verschmutzungsgrades bzw. der Trübung des Wasch- oder Spülwassers wird ein an sich bekannter Sensor eingesetzt, der fähig ist, eine Aussage über den jeweiligen Zustand bzw. Fortgang des Wasch- oder Spülprozesses zu liefern. Der für eine bestimmte Zeitdauer ermittelte Anstieg der Wasch- oder Spülwassertrübung (Verschmutzung) kann als "Reinigungsgeschwindigkeit" angesehen werden. Die Erhöhung der Wasch- oder Spülwassertemperatur nach dem ersten Meßvorgang wird zweckmäßig nach einem fest vorgegebenen oder abgeleiteten Zeitpunkt vorgenommen. Danach wird durch einen zweiten Meßvorgang durch Ermittlung des Verschmutzungsgrades bzw. der Trübung des Wasch- oder Spülwassers wiederum die "Reinigungsgeschwindigkeit" bestimmt. Aus diesen beiden Messungen wird eine Betriebsgröße abgeleitet, die als "Reinigungsleistung" pro aufgewendeter Energie definiert werden kann. Dabei wird beim ersten Meß- und Auswertevorgang der Antriebsenergieverbrauch während einer bestimmten Zeiteinheit und beim zweiten Meß- und Auswertevorgang der Energieeinsatz zur Erhöhung der Wasch- oder Spülwassertemperatur von einen Ist- auf einen Sollwert berücksichtigt. Durch einen Vergleich beider Meß- bzw. Betriebsgrößen kann nun durch eine entsprechende Steuereinrichtung entschieden werden, ob es energetisch günstiger ist, die "Reinigungsleistung" über eine längere Waschzeit bei gleicher Waschtemperatur oder über eine höhere Waschtemperatur zu erreichen. Bei diesem Auswertungsvorgang können zweckmäßig auch weitere bekannte Parameter wie Wäscheart, Wäschemenge, gebundene Flotte usw. sowie andere Programmwünsche des Benutzers, wie z. B. ein Waschkurzprogramm mit einfließen bzw. berücksichtigt werden. Als Steuereinrichtung für den beschriebenen Zweck kommt in vorteilhafter Weise ein sogenannter Fuzzy- Prozessor mit Fuzzy-Schlußfolgerungs-Einrichtung zur Anwendung. Durch eine kontinuierliche Erfassung und Auswertung der genannten Meß- bzw. Betriebsgrößen kann ein Minimum an elektrischer Energie für eine maximale Reinigungsleistung automatisch erreicht werden. Als selbstverständlich wird dabei vorausgesetzt, daß ein solcher Wasch- oder Spülprozeß durch Grenzwerte, beispielsweise maximale Waschtemperatur, maximale Wasch- oder Spülzeit, überwacht wird. Wenn kein merklicher Gewinn beim Waschergebnis durch Zeitverlängerung oder durch eine Temperaturerhöhung mehr erreicht werden kann, wird der betreffende Wasch- bzw. Spülvorgang abgebrochen.This object is now achieved according to the invention in that during the initial phase of washing or Rinsing process by a measurement and evaluation process reached during a certain period of time  Degree of contamination or the cloudiness of the washing or Rinsing water is determined that after a certain Time the temperature of the washing or rinsing water increases and the above-mentioned measurement and evaluation process is repeated and that from each of the two measuring processes one on the energy consumed for a particular sales stage related measured variable (company variable) is derived and that after evaluating these parameters, the most energy-efficient The course of the washing or rinsing process is determined and is carried out. The proposed measures will one tailored to the respective item of laundry Optimized energy consumption and functional results Washing program sequence automatically selected and by the Program control device processed. To measure the Degree of pollution or the cloudiness of the washing or Rinsing water, a sensor known per se is used, who is able to make a statement about the respective state or to continue the washing or rinsing process. The increase in washing determined for a certain period of time or rinse water turbidity (pollution) can be considered "Cleaning speed" can be viewed. The increase the wash or rinse water temperature after the first Measuring process is expedient after a fixed predetermined or derived time. After that, through a second measurement process by determining the Degree of pollution or the cloudiness of the washing or Rinsing water in turn the "cleaning speed" certainly. These two measurements become one Company size derived as "cleaning performance" per energy used can be defined. Doing so during the first measurement and evaluation process Driving energy consumption during a given Unit of time and in the second measurement and evaluation process Use of energy to increase washing or Rinse water temperature from an actual to a setpoint  considered. By comparing the two measurement or Company sizes can now be determined by a corresponding Control device can be decided whether it is energetic is cheaper, the "cleaning performance" over a longer period Washing time at the same washing temperature or over a to achieve a higher washing temperature. With this Evaluation process can expediently also other known Parameters such as type of laundry, amount of laundry, bound fleet, etc. as well as other program requests of the user, such as. B. a Short washing program included or taken into account will. As a control device for the purpose described a so-called fuzzy Processor with fuzzy reasoning facility for Application. Through continuous recording and Evaluation of the above-mentioned measured and operating variables can be carried out Minimum of electrical energy for a maximum Cleaning performance can be achieved automatically. As of course, it is assumed that a such washing or rinsing process through limit values, for example maximum washing temperature, maximum washing or rinsing time is monitored. If not a noticeable gain in the washing result by lengthening the time or by a Temperature increase can be achieved, the relevant washing or rinsing process canceled.
