Description

Programmsteuerungsverfahren für ein wasserführendes Haushaltsgerät, insbesondere einen Geschirrspüler.Program control method for a water-bearing household appliance, especially a dishwasher.

Die Steuerungen heutiger wasserführender Haushaltsgeräte wie Waschmaschinen und Geschirrspülmaschinen sind nur bedingt auf Warmwasseranschlüsse ausgelegt. Sie reagieren nicht auf unterschiedliche Wassereinlauftemperaturen und den sich dabei einstellenden Temperaturen im Haushaltsgerät. Bei Warmwasseranschluß erhöht sich nach jedem Wasch- oder Spülschritt, d.h. nach jedem Wasserwechsel, die Temperatur im Geschirrspüler oder in der Waschmaschine solange bis maximal die Zulauftemperatur erreicht ist. Durch die Erhöhung der Temperatur in den Wasch- oder Spülschritten verkürzen sich die Aufheizzeiten der warmen Spülgänge wie Reinigen und Klarspülen. Die Reinigungs- und Klarspülzeiten sind damit nicht mehr sichergestellt bzw. die Einwirkzeiten für das Reinigungs- und Klarspülmittel sind zu kurz. Ein schlechtes Reinigungs- und Trockenergebnis können die Folge sein.The controls of today's water-bearing household appliances such as Washing machines and dishwashers are only limited Hot water connections designed. They don't respond to different ones Water inlet temperatures and the resulting ones Temperatures in the household appliance. With hot water connection increases after each washing or rinsing step, i.e. after every water change, the temperature in the dishwasher or in the washing machine until the maximum inlet temperature is reached. By increasing the temperature in the washing or rinsing steps shorten the warm-up times of the warm ones Rinse cycles such as cleaning and rinsing. The cleaning and Rinse aid times are no longer ensured or Exposure times for the detergent and rinse aid are too short. Poor cleaning and drying results can Be consequence.

In der DE 40 41 108 wird ein Verfahren zum Betrieb eines programmgesteuerten Haushaltsgeräts, insbesondere einer Geschirr spülmaschine mit einem Programmschalter beschrieben, die wenigstens die Schritte Reinigen und Klarspülen mit Warmwasser umfassen. Die Programmsteuerung des Gerätes ist dabei um eine anwählbare Programmvariante ergänzt, durch welche die geräteeigene Heizung bei mindestens einem mit Warmwasser durchzuführenden Spülprogramm ständig ausgeschaltet wird.DE 40 41 108 describes a method for operating a program-controlled Household appliances, especially dishes Dishwasher with a program switch described, at least include the steps of cleaning and rinsing with hot water. The program control of the device is a selectable one Program variant supplemented by which the device's own Heating at least one to be carried out with hot water Washing program is constantly switched off.

Die Erfindung der DE 43 04 382 beschreibt wasserführende Haushaltgeräte mit einer Programmsteuereinrichtung mit einer Programmwahleinrichtung, mit Bedienelementen zur Anwahl eines Wasch- oder Spülprogramms und mit Anschlüssen für die Wasserversorgung. Die Anschlüsse für die Wasserversorgung sind sehr variabel, z. B. für Warmwasser, Recyclingwasser, Regenwasser usw. Die Programmsteuereinrichtung ist an das angeschlossene zusätzliche Wasserversorgungssystem anpassbar.The invention of DE 43 04 382 describes water-carrying household appliances with a program control device with a program selection device, with controls for selecting one Washing or rinsing program and with connections for the water supply. The connections for the water supply are very variable, e.g. B. for hot water, recycling water, rain water etc. The program control device is connected to the additional water supply system customizable.

Eine weitergehende Erfindung wird in der DE 43 36 837 beschrieben. Die Erfindung nutzt dabei externe Warmwasserzentralanlagen für die Wasserfüllung des Haushaltsgeräts und die BUS-Technik zur Optimierung des Energieaufwandes für die Warmwasserfüllung im Haushaltsgerät. Dabei wird die Temperatur des aus der Zentralanlage dem Haushaltsgerät zufließenden Warmwassers gemessen, das zufließende Warmwasser mit einer ungenügenden Temperatur verworfen und anderweitig genutzt und erst das zufließende Warmwasser mit einer ausreichenden Temperatur für einen Spül- oder Waschprozess verwendet. Hierbei werden verhältnismäßig komplizierte Berechnungen vorgenommen und Informationen vom vorhanden Wärmeinhalt der Zentralanlage übermittelt, d. h. das Haushaltgerät wird laufend darüber informiert, wieviel Warmwasser mit welcher Temperatur in der Zentralanlage zur Verfügung steht. Aufgrund des vom Benutzer angewählten Wasch- oder Spülvorganges überprüft dann das Haushaltgerät, ob der Einsatz des zur Verfügung stehenden warmen Zulaufwassers einen energetischen Vorteil erbringt. Dies bedingt jedoch die Installation einer kostenaufwendigen Haus-BUS-Technik im Gebäudestandort des Haushaltsgeräts. Das Leitungswasser wird dabei erst bei ausreichend hoher Temperatur für einen Wasch- oder Spülprozeß verwendet.A further invention is described in DE 43 36 837. The invention uses external hot water central systems for water filling the household appliance and BUS technology to optimize the energy consumption for hot water filling in the household appliance. The temperature of the central system hot water flowing to the household appliance is measured, the inflowing hot water with an insufficient temperature discarded and otherwise used and only the inflowing Hot water with a sufficient temperature for a rinse or washing process used. This will be proportionate complicated calculations and information from existing heat content transmitted to the central system, d. H. the Household appliance is continuously informed about how much hot water at what temperature is available in the central system stands. Due to the washing or rinsing process selected by the user then the household appliance checks whether the use of the available warm inlet water an energetic Brings advantage. However, this requires installation an expensive house bus technology in the building location of the Household appliance. The tap water is only sufficient if high temperature used for a washing or rinsing process.

Der Erfindung liegt die Aufgabe zugrunde, die Wasch- oder Spülvorgänge von Haushaltsgeräten abhängig von unterschiedlichen Wassereinlauftemperaturen zu optimieren.The invention is based, the washing or rinsing task of household appliances depending on different To optimize water inlet temperatures.

Diese Aufgabe wird durch ein Programmsteuerungsverfahren für ein wasserführendes Haushaltsgerät erreicht, wobei in Abhängigkeit der Wassereinlauftemperatur die Waschzeiten der einzelnen Waschschritte im Programm automatisch verändert werden und/oder einzelne Waschschritte ein oder aus geblendet werden.This task is accomplished through a program control process for reached a water-bearing household appliance, depending on the water inlet temperature the washing times of the individual Washing steps in the program can be changed automatically and / or individual washing steps can be shown or hidden.

Nach einer vorteilhaften Ausbildung der Erfindung wird am Anfang jedes Waschschrittes die Temperatur des Wassers im Haushaltsgerät gemessen, wobei die ermittelte Temperatur die Dauer des jeweiligen Waschschrittes bestimmt. Bei sogenannten "kalten" Waschschritten werden um so kürzere Waschzeiten eingestellt je höher die Wassertemperatur ist und bei sogenannten "warmen" Waschschritten werden um so längere Waschzeiten eingestellt, je höher die Wassertemperatur ist.After an advantageous embodiment of the invention is at the beginning the temperature of the water in the household appliance in each washing step measured, the determined temperature the duration of the respective washing step. With so-called "cold" Washing steps are set the shorter the washing times the higher the water temperature and so-called "warm" washing steps are set the longer the washing times, the higher the water temperature is.

Ein Ausführungsbeispiel der Erfindung wird im folgenden näher am Beispiel eines Programmablaufes einer Geschirrspülmaschine beschrieben. Das Steuerungsverfahren des Warmwasserzulaufes und der einzelnen Programme erfolgt in Abhängigkeit der Wassertemperatur nach dem Einlauf in den Geschirrspüler. Die Wassertemperatur wird dabei zweckmäßigerweise im Sumpf des Geschirrspülers gemessen. Entsprechend der gemessenen Spülwassertemperatur werden die Waschzeiten entweder verlängert oder verkürzt und/oder einzelne Spülschritte werden ein- oder ausgeblendet. Vor jedem Spülschritt wie z.B. Vorspülen, Reinigen, Zwischenspülen und Klarspülen, wird die erreichte Wassertemperatur nach Beendigung der Wasseraufnahme ermittelt. Diese Temperatur bestimmt dann die Dauer des jeweiligen Spülschritts. Sogenannte kalte Spülschritte, wie Vorspülen und Zwischenspülen werden zeitlich so eingestellt, daß eine höhere Temperatur die Länge der Spüldauer verkürzt. Bei sogenannten warmen Spülschritten, wie Vorspülen, Reinigen und Klarspülen wird die Spüldauer verlängert, je höher die gemessene Temperatur ist.An embodiment of the invention is described in more detail below using the example of a program sequence of a dishwasher described. The control process of the hot water supply and of the individual programs depends on the water temperature after entering the dishwasher. The water temperature is expediently in the sump of the dishwasher measured. According to the measured rinse water temperature the washing times are either extended or shortened and / or individual rinsing steps are shown or hidden. Before each rinsing step, e.g. Prewash, clean, rinse and rinse, the water temperature reached after End of water intake determined. This temperature determines then the duration of the respective rinsing step. So-called cold rinsing steps, such as pre-rinsing and intermediate rinsing timed so that a higher temperature the length the flushing time is reduced. With so-called warm rinsing steps, like pre-rinsing, cleaning and rinsing, the rinsing time is extended, the higher the measured temperature.

Bei der Nutzung eines Warmwasseranschlusses erhöht sich durch jeden einzelnen Wasserwechsel die Anfangstemperatur im Geschirrspüler bis maximal auf die Wassereinlauftemperatur. Wird beim zweiten Wasserwechsel für den Reinigungsspülgang nicht mindestens die vorgegebene Temperatur, z.B. 50 °C erreicht, so kann weiteres Wasser zugeführt oder sogar ein erneuter Wasserwechsel durchgeführt werden, so lange bis die vorgegebene Temperatur erreicht ist. Erst dann wird der eigentliche Reinigungsvorgang mit der Dosierung des Reinigers gestartet.When using a hot water connection increases by the initial temperature in the dishwasher every time the water is changed up to a maximum of the water inlet temperature. Becomes not with the second water change for the cleaning rinse cycle at least the specified temperature, e.g. Reached 50 ° C, see above can add more water or even change the water again be carried out until the specified temperature is reached. Only then will the actual cleaning process started with the dosage of the cleaner.

Sollte die gewünschte Wassertemperatur auch durch einen erneuten Wasserwechsel nicht erreichbar sein, so kann die Geräteheizung zu geschaltet werden. Mit einer aufwendigen Programmsteuerung könnte beispielsweise die Zunahme der Temperatur pro Zeiteinheit gemessen werden und abhängig von der Geschwindigkeit der Temperaturzunahme die Zuschaltung der Geräteheizung gesteuert werden. Aus einer langsamen Temperaturzunahme könnte z.B. gefolgert werden, daß die gewünschte Temperatur nicht erreichbar ist oder erst nach Verbrauch von zuviel Warmwasser erreichbar ist, so daß es günstiger wäre, die Geräteheizung zuzuschalten. Durch die Möglichkeit der Zuschaltung der Geräteheizung kann aber auch vermieden werden, daß z.B. Wasser mit einer Temperatur von bereits z.B. 48 °C nochmals abgepumpt wird.Should the desired water temperature also be achieved by If the water change cannot be reached, the device heating can to be switched. With complex program control for example, the increase in temperature per Unit of time can be measured and depends on the speed the temperature increase the connection of the device heating to be controlled. From a slow increase in temperature e.g. be concluded that the desired temperature cannot be reached is or can only be reached after too much hot water has been consumed is, so that it would be cheaper to switch on the device heating. Due to the possibility of switching on the device heating can also be avoided that e.g. Water with a Temperature of already e.g. 48 ° C is pumped out again.

Beim Wasserwechsel für das Klarspülen wird ebenfalls in Abhängigkeit der Wassertemperatur Wasser nachgelassen oder ein zusätzlicher Wasserwechsel für das Klarspülen ausgeführt bis etwa 60 °C erreicht sind. Erst dann wird der Klarspüler dosiert.When changing the water for rinsing is also dependent the water temperature water decreased or an additional Water change carried out for rinsing until about 60 ° C are reached. Only then is the rinse aid dispensed.
