Description

Die Erfindung betrifft ein Verfahren zur Erkennung der Geschirrmenge im Spülbehälter einer Geschirrspülmaschine sowie eine Geschirrspülmaschine zur Durchführung dieses Verfahrens.The invention relates to a method for detecting the amount of dishes in the washing container of a dishwasher and a dishwasher for carrying out this method.

Bei der Entwicklung von neuen Geschirrspülmaschinen und Spülprogrammen wird in besonderem Maße eine Reduktion des Energieverbrauchs angestrebt, da Haushaltsgeräte, insbesondere Geschirrspülmaschinen, aufgrund ihres Energieverbrauchs kategorisiert werden.In the development of new dishwashers and washing programs, a particular aim is to reduce energy consumption, since domestic appliances, in particular dishwashers, are categorized on the basis of their energy consumption.

Ein wesentlicher Bestandteil des Energieverbrauchs wird bei der Aufheizung der Spülflotte aufgewandt, da, abhängig von dem gewählten Spülprogramm in jedem Teilprogrammabschnitt eine Flüssigkeitsmenge von etwa 3 bis 6 Liter um eine Temperaturdifferenz von bis zu 50° C aufgeheizt werden muß. Um den Energieverbrauch während eines Spülprogramms zu reduzieren, gibt es bei herkömmlichen Geschirrspülmaschinen die Möglichkeit, ein Sparprogramm manuell vorzuwählen, durch das der Wasserverbrauch wesentlich reduziert oder durch Auswahl eines sogenannten Einzelkorbspülens durch das der Wasserverbrauch bis etwa halbiert, jedenfalls ebenfalls wesentlich reduziert werden kann.An essential part of the energy consumption is expended in the heating of the wash liquor, since, depending on the selected wash program in each part program section, a liquid amount of about 3 to 6 liters must be heated by a temperature difference of up to 50 ° C. To reduce the energy consumption during a wash program, there is the possibility in conventional dishwashers to preselect a savings program by which the water consumption significantly reduced or by choosing a so-called Einzelkorbspülens by the water consumption to about half, in any case can also be substantially reduced.

Ziel dieser Wahlmöglichkeiten ist es, das jeweilige Spülprogramm und damit die notwendige Wassermenge, auf die jeweilige Geschirrmenge optimal anzupassen. Die oben erläuterten, bekannten Einsparungsmöglichkeiten, das Sparprogramm oder das Einzelkorbspülen, muß der Benutzer selbst vorwählen. Bei einer ungünstigen Beladung der einzelnen Geschirrkörbe (zum Beispiel durch größere Töpfe) kann ein Einzelkorbspülen jedoch nicht auswählt werden, da trotz geringer Anzahl von Geschirr dieses aufgrund der Größe der einzelnen Geschirrteile auf zwei Geschirrkörbe im Spülbehälter verteilt ist. Da die Geschirrmenge nicht genau eingestellbar und lediglich zwischen groben Geschirrzuständen unterschieden werden kann, wird eine größere Flüssigkeitsmenge aufgewandt, als aufgrund der Geschirrmenge notwendig ist.The aim of these options is to optimally adapt the respective wash program and thus the necessary amount of water to the respective amount of dishes. The above explained, known saving options, the economy program or the Einzelkorbspülen, the user must select himself. In an unfavorable loading of the individual baskets (for example, by larger pots) a Einzelkorbspülen can not be selected, however, because despite the small number of dishes this is distributed due to the size of the individual dishes on two baskets in the washing. Since the amount of dishes can not be precisely adjusted and can only be distinguished between coarse dish conditions, a larger amount of liquid is used than is necessary due to the amount of dishes.

Beim Verfahren nach EP-A-0 727 179 wird ein beladungs abhängiger Benetzungswert entsprechend der für das Benetzen des Spülgutes erforderlichen Wassermenge ermittelt, um eine beladungs abhängige Änderung des Spülprogramms durchzuführen.In the process after EP-A-0 727 179 a load-dependent wetting value is determined according to the amount of water required for wetting the items to be washed in order to carry out a loading-dependent change of the wash program.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren, welches dazu geeignet ist, die Geschirrmenge im Spülbehälter einer Geschirrspülmaschine so zu erkennen, dass eine Programmsteuerung das Spülprogramm an die jeweilige Geschirrmenge anpasst sowie eine Geschirrspülmaschine zur Durchführung dieses Verfahrens bereitzustellen.The object of the present invention is therefore to provide a method which is suitable for detecting the quantity of dishes in the washing container of a dishwasher in such a way that a program control adapts the washing program to the respective quantity of dishes and to provide a dishwasher for carrying out this method.

Diese Aufgabe wird durch das erfindungsgemäße Verfahren mit den Merkmalen gemäß Anspruch 1 sowie durch die Geschirrspülmaschine mit den Merkmalen gemäß des weiteren unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind in den Unteransprüchen gekennzeichnet.This object is achieved by the method according to the invention with the features according to claim 1 and by the dishwasher with the features according to the further independent claim. Advantageous developments of the method according to the invention are characterized in the subclaims.

Beim erfindungsgemäßen Verfahren zur Erkennung der Geschirrmenge im Spülbehälter einer Geschirrspülmaschine werden sowohl die Motorbetriebsdaten einer Umwälzpumpe als auch die Heizungssteigung in der Geschirrspülmaschine wenigstens in einer Vorspülphase und in einer Aufheizphase erfasst und die erfassten Ist-Werte mit hinterlegten Soll-Werte verglichen, aufgrund dieses Soll-Ist-Wert-Vergleichs wird die im Spülbehälter befindliche Geschirrmenge festgestellt und das Spülprogramm aufgrund der festgestellten Geschirrmenge entsprechend angepasst.In the inventive method for detecting the amount of dishes in the washing compartment of a dishwasher, both the engine operating data of a circulating pump and the heating gradient in the dishwasher are detected at least in a pre-purge phase and in a heating phase, and the detected actual values are compared with stored desired values, on the basis of this setpoint value. Actual value comparison, the amount of dishes located in the washing container is determined and the washing program adjusted accordingly due to the detected amount of dishes.

Vorteilhafterweise erfolgt die Messung der Motorbetriebsdaten und Heizsteigung in bestimmten Zeitintervallen.Advantageously, the measurement of the engine operating data and heating slope takes place at specific time intervals.

Anhand der Motorbetriebsdaten ist es möglich, die durch die Umwälzpumpe gepumpte Wassermenge zu bestimmen und so zum Beispiel fehlende Wassermengen, die sich im Geschirr sammeln oder am Geschirr anhaften, zu messen. Diese Messgröße kann Aufschluss über die im Spülbehälter befindliche Geschirrmenge geben.Based on the engine operating data, it is possible to determine the amount of water pumped by the circulation pump and thus to measure, for example, missing amounts of water that collect in the dishes or adhere to the dishes. This measured variable can provide information about the amount of dishes in the washing container.

Erfindungsgemäß werden jedoch nicht nur die Motorbetriebsdaten zur Erkennung der Geschirrmenge im Spülbehälter verwendet, sondern auch der Temperaturwert, der für die Aufheizung der Spülflotte notwendig ist. Dieser als Heizsteigung bekannte Wert misst über einen Temperaturfühler, der zum Beispiel an einem Ausgang des Durchlauferhitzers oder einer anderen Heizquelle, die zur Aufheizung der Spülflotte bestimmt ist, angeordnet ist, die Temperaturänderung des durchströmenden Wassers.According to the invention, however, not only the engine operating data are used to detect the amount of dishes in the washing, but also the temperature value that is necessary for the heating of the rinsing liquor. This known as Heizsteigung value measures via a temperature sensor, which is located for example at an outlet of the water heater or other heating source, which is intended for heating the rinsing water, the temperature change of the water flowing through.

Wird beispielsweise eine bestimmte Menge Wasser im Durchlauferhitzer aufgeheizt und mittels wenigstens einer Sprühvorrichtung auf das Geschirr gelenkt, so findet ein Temperaturausgleich zwischen Geschirr und der Spülflotte statt, wobei die Temperaturänderung bzw. die Geschwindigkeit der Temperaturänderung abhängig von der jeweiligen Menge an Geschirr im Spülbehälter ist. Je mehr Geschirr im Spülbehälter angeordnet ist, desto langsamer heizt sich die Spülflotte während der Aufheizphase auf, da stets aufgrund der Aufheizung des Geschirrs eine entsprechende Abkühlung der Spülflotte stattfindet. Während der Aufheizphase wird die Spülflotte mittels Umwälzpumpe mehrmals durch die Heizeinrichtung, zum Beispiel den Durchlauferhitzer, gepumpt, so dass ein Messen der Wassertemperatur zum Beispiel am Durchlauferhitzeraus- oder -eingang sinnvoll ist.For example, if a certain amount of water is heated in the water heater and directed by at least one sprayer on the dishes, a temperature compensation between dishes and the rinsing takes place, the temperature change or the rate of change in temperature is dependent on the amount of crockery in the washing. The more dishes are arranged in the washing, the slower the washing liquor heats up during the heating phase, as always due to the heating of the dishes, a corresponding cooling of the wash liquor takes place. During the heating phase, the rinsing liquor is pumped by circulation pump several times through the heater, for example, the water heater, so that a measurement of the water temperature, for example, at the water heater outlet or input makes sense.

Die alleinige Verwendung der Daten zur Heizsteigung zur Erkennung der Geschirrmenge im Spülbehälter ist indes nicht ausreichend zuverlässig, da aufgrund der stets vorhandenen Spannungsunterschiede im öffentlichen Stromnetz die Heizsteigungsdaten wesentlich verfälscht werden können. Wird zum Beispiel die Geschirrspülmaschine bei einer Spannung von 250 Volt anstatt 230 Volt Wechselspannung betrieben, so würde die Heizsteigungsmessung alleine aufgrund der hohen, zur Verfügung stehenden, elektrischen Leistung auch bei einem Spülbehälter, der mit Spülgut beladen ist, den Beladungszustand unterschätzen und ein Signal an das Programmsteuergerät weitergeben, dass die Geschirrspülmaschine leer sei.However, the sole use of the data for Heizsteigung to detect the amount of dishes in the washing is not sufficiently reliable, since due to the ever-present voltage differences in the public grid, the Heizsteigungsdaten can be significantly distorted. For example, if the dishwasher is operated at a voltage of 250 volts instead of 230 volts AC, then the Heizsteigungsmessung would underestimate the loading state and a signal even due to the high, available electrical power even in a washing container, which is loaded with dishes Pass the program control unit that the dishwasher is empty.

Die Betriebsdaten des Motors hingegen verändern sich ebenfalls mit der Spannung, d.h. die Änderung der Spannung bzw. Spannungsschwankungen werden gemessen und können somit in die Beurteilung der Heizsteigungswerte einfließen bzw. diese verifizieren.The operating data of the motor, on the other hand, also varies with the voltage, i. the change in the voltage or voltage fluctuations are measured and can thus be incorporated in the assessment of the Heizsteigungswerte or verify.

Erst durch die Verknüpfung der beiden Messdaten, Motorbetriebsdaten und Heizsteigung läßt sich erfindungsgemäß zuverlässig die Geschirrmenge im Spülbehälter bestimmen, da eine Abweichung der Motorbetriebsdaten aufgrund von Spannungsänderungen ermittelt und ausgeglichen werden kann.Only by linking the two measured data, engine operating data and heating gradient can be inventively reliably determine the amount of dishes in the washing, since a deviation of the engine operating data due to voltage changes can be determined and compensated.

Hierzu sind im Programmsteuergerät eine Vielzahl von Kurven- oder Meßdatenszenarien hinterlegt, die jeweils eine bestimmte Geschirrmenge zum Ergebnis haben und entsprechend charakteristische Kurvenverläufe von Motorbetriebsdaten und Heizsteigung, Soll-Werte, aufweisen. Anhand dieser "ermittelten" Geschirrmenge ist es möglich den Wasserbedarf für das ausgewählte Spülprogramm optimiert auf die jeweilige Geschirrmenge einzustellen.For this purpose, a plurality of curve or Meßdatenszenarien are stored in the program control unit, each of which has a certain amount of dishes result and corresponding characteristic curves of engine operating data and Heizsteigung, target values, have. Based on this "determined" amount of dishes, it is possible the need for water optimized for the selected wash program to the respective set of dishes.

Das erfindungsgemäße Verfahren verknüpft somit zwei voneinander unabhängig gewonnene Messwerte, die auf unterschiedliche Eingangsgrößen, Ist-Werte, zurückzuführen sind. Nachdem das erfindungsgemäße Verfahren die Geschirrmenge im Spülbehälter erkannt hat, kann die für diese bestimmte Geschirrmenge ausreichende Wassermenge, die ebenfalls durch empirische Messdaten ermittelt worden ist und im Programmsteuergerät hinterlegt wurden, bestimmt werden, so dass der Wasserverbrauch aufgrund der automatischen Wassermengenanpassung wesentlich reduziert werden kann.The method according to the invention thus combines two measured values obtained independently of one another, which can be attributed to different input variables, actual values. After the method according to the invention has recognized the amount of dishes in the washing container, the amount of water sufficient for this particular set of dishes, which has also been determined by empirical measurement data and stored in the program control unit, can be determined, so that the water consumption can be substantially reduced due to the automatic water quantity adjustment.

Mit der vorliegenden Erfindung ist es gelungen, ein Verfahren, welches dazu geeignet ist, die Geschirrmenge im Spülbehälter einer Geschirrspülmaschine so zu erkennen, dass eine Programmsteuerung das Spülprogramm an die jeweilige Geschirrmenge anpasst, bereitzustellen.With the present invention, it has been possible to provide a method which is suitable for detecting the quantity of dishes in the washing container of a dishwasher so that a program control adapts the washing program to the respective quantity of dishes.

In der erfindungsgemäßen Geschirrspülmaschine zur Durchführung des erfindungsgemäßen, vorgeschilderten Verfahrens werden sowohl die Motorbetriebsdaten der Umwälzpumpe als auch die Heizungssteigung mittels geeigneter Sensoren wenigstens in einer Vorspülphase und in einer Aufheizphase erfasst, wobei die Geschirrspülmaschine eine Programmsteuerung aufweist, in der die erfassten Ist-Werte mit hinterlegten Soll-Werte verglichen werden, aufgrund dieses Soll-Ist-Wert-Vergleichs die im Spülbehälter befindliche Geschirrmenge festgestellt und das Spülprogramm aufgrund der festgestellten Geschirrmenge entsprechend angepasst wird. Damit werden die oben geschilderten Vorteile des erfindungsgemäßen Verfahrens in der erfindungsgemäßen Geschirrspülmaschine genutzt.In the dishwasher according to the invention for carrying out the method according to the invention, both the motor operating data of the circulation pump and the heating gradient are detected by means of suitable sensors at least in a pre-purge phase and in a heating phase, wherein the dishwasher has a program control in which the detected actual values are stored Target values are compared, determined based on this target-actual value comparison, the amount of dishes located in the washing and the wash program is adjusted accordingly due to the detected amount of dishes. Thus, the above-described advantages of the method according to the invention in the dishwasher according to the invention are used.

Mit der vorliegenden Erfindung ist es weiterhin gelungen, eine Geschirrspülmaschine zur Durchführung dieses Verfahrens bereitzustellen.With the present invention, it has furthermore been possible to provide a dishwasher for carrying out this method.
