Description

Die Erfindung betrifft ein wasserführendes Hausgerät, insbesondere ein Wäschebehandlungsgerät zum Waschen von Wäsche. Speziell betrifft die Erfindung das Gebiet der Waschmaschinen und Waschtrockner.The invention relates to a water-bearing domestic appliance, in particular a laundry treatment appliance for washing laundry. In particular, the invention relates to the field of washing machines and washer-dryers.

Aus der DE 29 49 254 A1 sind ein Verfahren und eine Vorrichtung zum Überwachen und Steuern eines Programms, insbesondere des Wasserzulaufs und der Reinigungszugabe, bei automatischen Waschmaschinen bekannt. Hierbei wird zum Überwachen und Steuern des Programms in Abhängigkeit bestimmter Konzentrationsgehalte von in der Spülflüssigkeit gelösten Reinigungszusätzen die Zahl der Spülgänge und die Dosierung der Reinigungszugabe gesteuert. Beispielsweise werden die Spülgänge beendet, wenn die Konzentration eines optischen Aufhellers des Reinigungsmittels in der Spülflüssigkeit auf einen Mindestgehalt gesunken ist. Hierbei überwacht ein Sensor die optischen Eigenschaften der Reinigungs- beziehungsweise Spülflüssigkeit oder deren Bestandteile, wobei über eine Auswerteschaltung Steuerimpulse für die nötige Zahl der Spülgänge an ein Programmschaltwerk und an eine Dosiereinrichtung zur Dosierung der noch erforderlichen Reinigungs- beziehungsweise Spülmittelmenge geliefert werden.From the DE 29 49 254 A1 a method and a device for monitoring and controlling a program, in particular the water supply and the addition of cleaning agents, are known in automatic washing machines. In order to monitor and control the program, the number of wash cycles and the dosage of the cleaning additive are controlled as a function of certain concentration levels of cleaning additives dissolved in the washing liquid. For example, the wash cycles are ended when the concentration of an optical brightener in the cleaning agent in the wash liquid has dropped to a minimum level. Here, a sensor monitors the optical properties of the cleaning or rinsing liquid or its components, with control pulses for the required number of rinsing cycles being supplied to a program switch and to a metering device for metering the amount of cleaning or rinsing agent still required via an evaluation circuit.

Aufgabe der Erfindung ist es, ein wasserführendes Hausgerät zu schaffen, bei dem die Bedienbarkeit verbessert ist und gegebenenfalls eine ressourcenschonende Programmdurchführung erzielbar ist.The object of the invention is to create a water-bearing domestic appliance in which the operability is improved and, if necessary, a resource-saving program execution can be achieved.

Die Aufgabe wird durch ein wasserführendes Hausgerät, insbesondere ein Wäschebehandlungsgerät zum Waschen von Wäsche, gemäß Anspruch 1 gelöst. Bei dem wasserführenden Hausgerät sind ein Behandlungsbereich, ein Behandlungsmittelbehälter, der zum Bevorraten zumindest eines Behandlungsmittels dient, eine Dosiereinrichtung, die zum Zumessen des Behandlungsmittels für den Behandlungsbereich dient, und eine Steuerung vorgesehen, wobei die Steuerung mehrere Behandlungsprogramme aufweist und zum Ansteuern der Dosiereinrichtung entsprechend einem von einem Benutzer aus den Behandlungsprogrammen ausgewählten Behandlungsprogramm dient, wobei zumindest ein Behandlungsmittelparameter vorgesehen ist, der von einem Benutzer einstellbar ist, und wobei die Steuerung das ausgewählte Behandlungsprogramm in Abhängigkeit von dem Behandlungsmittelparameter ausführt.The object is achieved by a water-conducting domestic appliance, in particular a laundry treatment appliance for washing laundry, according to claim 1. In the case of the water-bearing domestic appliance, there is a treatment area, a treatment agent container, which is used to store at least a treatment agent is used, a metering device which is used to meter the treatment agent for the treatment area, and a controller is provided, the controller having several treatment programs and serving to control the metering device in accordance with a treatment program selected by a user from the treatment programs, at least one treatment agent parameter being provided which is adjustable by a user, and wherein the controller executes the selected treatment program as a function of the treatment agent parameter.

Durch die in den abhängigen Patentansprüchen aufgeführten Maßnahmen sind bevorzugte und vorteilhafte Weiterbildungen des erfindungsgemäßen wasserführenden Hausgeräts möglich.The measures listed in the dependent claims allow preferred and advantageous developments of the water-bearing domestic appliance according to the invention.

In vorteilhafter Weise kann ein Benutzer eine bedarfsgerechte Anpassung des Behandlungsprogramms über den Behandlungsmittelparameter erzielen. Beispielsweise kann eine bedarfsgerechte Anpassung der Behandlungsmitteldosiermenge bei Sicherstellung der gewünschten Behandlungswirkung und eines optimierten Behandlungsmittelverbrauchs erfolgen. Speziell kann eine bedarfsgerechte Anpassung der Waschmitteldosiermenge bei Sicherstellung der gewünschten Waschleistung und des Waschmittelverbrauchs erzielt werden. Beispielsweise kann ein Benutzer in Abhängigkeit von dem Verschmutzungsgrad der Wäsche den Behandlungsmittelparameter einstellen. Hierbei kann der Benutzer auch die Art der Wäsche, insbesondere die Empfindlichkeit des Gewebes, berücksichtigen.In an advantageous manner, a user can achieve a needs-based adaptation of the treatment program via the treatment agent parameter. For example, the treatment agent dosage amount can be adjusted as required while ensuring the desired treatment effect and an optimized treatment agent consumption. In particular, a need-based adjustment of the detergent dosage can be achieved while ensuring the desired washing performance and detergent consumption. For example, a user can set the treatment agent parameter as a function of the degree of soiling of the laundry. The user can also take into account the type of laundry, in particular the sensitivity of the fabric.

Herkömmlicherweise kann die Waschmitteldosierung über vom Waschmittelhersteller vorgegebene Anpassungen an die Verschmutzung, die Wasserhärte und die zugegebene Menge an zu behandelnden Textilien erfolgen. Zur Vereinfachung der Dosierung für den Benutzer ist es erfindungsgemäß, dass die Steuerung eine Beladung des Behandlungsbereichs erfasst und dass die Steuerung die Dosiereinrichtung in Abhängigkeit von zumindest dem Behandlungsparameter und der erfassten Beladung des Behandlungsbereichs entsprechend dem ausgewählten Behandlungsprogramm ansteuert. Ferner kann eine Wasserhärte hinterlegt sein, die von der Steuerung beim Ansteuern der Dosiereinrichtung berücksichtigt wird.Conventionally, the detergent dosage can take place via adjustments specified by the detergent manufacturer to the soiling, the water hardness and the added amount of textiles to be treated. To simplify the dosing for the user, it is according to the invention that the controller detects a loading of the treatment area and that the controller controls the dosing device depending on at least the treatment parameter and the detected loading of the treatment area in accordance with the selected treatment program. Furthermore, a water hardness can be stored that is taken into account by the control when activating the metering device.

Erfindungsgemäß ist es, dass eine mit der Steuerung verbundene Eingabeeinrichtung vorgesehen ist und dass die Eingabeeinrichtung eine Änderung des Behandlungsmittelparameters zum Einstellen des Behandlungsmittelparameters durch den Benutzer ermöglicht. Dadurch wird die Einstellung des Behandlungsmittelparameters für den Benutzer erleichtert. Außerdem können bestimmte Bereiche oder bestimmte Werte für den Behandlungsmittelparameter vorgegeben sein, um eine Fehlbedienung zu vermeiden und das Einstellen weiter zu erleichtern.According to the invention, an input device connected to the control is provided and that the input device enables the treatment agent parameter to be changed by the user in order to set the treatment agent parameter. This makes it easier for the user to set the treatment agent parameter. In addition, certain ranges or certain values can be specified for the treatment agent parameter in order to avoid incorrect operation and to further facilitate the setting.

Erfindungsgemäß ist es ferner, dass eine mit der Steuerung verbundene Anzeigeeinrichtung vorgesehen ist, dass die Steuerung beim Ändern des Behandlungsmittelparameters zumindest eine charakteristische Programmeigenschaft des ausgewählten Behandlungsprogramms, die von dem Behandlungsmittelparameter abhängt, in Bezug auf den geänderten Behandlungsmittelparameter bestimmt und dass die Anzeigeeinrichtung die von der Steuerung bestimmte charakteristische Programmeigenschaft des ausgewählten Behandlungsprogramms anzeigt. Speziell ist es erfindungsgemäß, dass eine von der Anzeigeeinrichtung anzeigbare charakteristische Programmeigenschaft des ausgewählten Behandlungsprogramms eine erwartete Programmdauer, ein erwarteter Energiebedarf, oder ein erwarteter Wasserbedarf ist. Beispielsweise kann der Benutzer durch den Behandlungsmittelparameter die Dosiermenge eines Behandlungsmittels verändern. Durch eine erhöhte Menge des Behandlungsmittels kann beispielsweise die Programmdauer reduziert werden, was dem Benutzer dann unmittelbar angezeigt werden kann. Somit kann der Benutzer den Programmablauf in vorteilhafter Weise beeinflussen.According to the invention, it is furthermore that a display device connected to the control is provided, that when the treatment agent parameter is changed, the control determines at least one characteristic program property of the selected treatment program, which depends on the treatment agent parameter, in relation to the changed treatment agent parameter, and that the display device determines the treatment agent parameter Control displays certain characteristic program property of the selected treatment program. In particular, it is according to the invention that a characteristic program property of the selected treatment program that can be displayed by the display device is an expected program duration, an expected energy requirement, or an expected water requirement. For example, the user can use the treatment agent parameter to change the dosage amount of a treatment agent. By increasing the amount of treatment agent, for example, the program duration can be reduced, which can then be displayed to the user immediately. The user can thus advantageously influence the program sequence.

Vorteilhaft ist es auch, dass ein von dem Benutzer einstellbarer Behandlungsmittelparameter ein Behandlungsmitteltyp ist. Hierbei ist es ferner vorteilhaft, dass die Steuerung mehrere Behandlungsmitteltypen vorgibt, aus denen der Benutzer zum Einstellen des Behandlungsmitteltyps einen auswählt, wobei die Behandlungsmitteltypen ein Vollwaschmittel und/oder ein Feinwaschmittel und/oder ein Vollwaschmittelkonzentrat und/oder ein Feinwaschmittelkonzentrat und/oder ein Buntwaschmittel und/oder ein Buntwaschmittelkonzentrat umfassen. Hierbei ist es außerdem vorteilhaft, dass der Behandlungsmittelbehälter mehrere Kammern aufweist, die zum Aufnehmen mehrerer Behandlungsmittel dienen, dass die Dosiereinrichtung mehrere Dosierpumpen aufweist, die den Kammern des Behandlungsmittelbehälters zugeordnet sind, und dass die Steuerung beim Ausführen des ausgewählten Behandlungsprogramms in Abhängigkeit von dem eingestellten Behandlungsmitteltyp die einzelnen Dosierpumpen der Dosiereinrichtung ansteuert. Beispielsweise kann für ein bestimmtes Behandlungsprogramm, das vom Benutzer ausgewählt wird, ein Feinwaschmittel vorgesehen sein. Der Benutzer kann dann anstelle des Feinwaschmittels beispielsweise auch ein Buntwaschmittel auswählen, wodurch sich gegebenenfalls aufgrund einer erhöhten Reinigungswirkung die erwartete Programmdauer verkürzt, ein erwarteter Energiebedarf verringert und/oder ein erwarteter Wasserbedarf reduziert ist. Somit ist eine vorteilhafte Anpassung an die Wünsche des Benutzers möglich. Hierbei kann der Benutzer bestimmen, welche Ressource, insbesondere Zeit, Material, Energie, Wasserbedarf, ihm am wichtigsten ist. Hierbei kann in vorteilhafter Weise eine Anpassung an sich zeitlich ändernde Bedürfnisse des Benutzers ermöglicht werden.It is also advantageous that a treatment agent parameter that can be set by the user is a treatment agent type. It is also advantageous here that the controller specifies several types of treatment agents, from which the user selects one for setting the treatment agent type, the treatment agent types being a heavy duty detergent and / or a mild detergent and / or a heavy duty detergent concentrate and / or a mild detergent concentrate and / or a colored detergent and / or a colored detergent concentrate. It is also advantageous here that the treatment agent container has several chambers which are used to hold several treatment agents, that the metering device has several metering pumps that form the chambers of the treatment agent container are assigned, and that the controller controls the individual metering pumps of the metering device when executing the selected treatment program as a function of the type of treatment agent set. For example, a mild detergent can be provided for a specific treatment program that is selected by the user. Instead of the mild detergent, the user can, for example, also select a colored detergent, which may shorten the expected program duration due to an increased cleaning effect, reduce an expected energy requirement and / or reduce an expected water requirement. An advantageous adaptation to the wishes of the user is thus possible. The user can determine which resource, in particular time, material, energy, water requirement, is most important to him. Here, an adaptation to the needs of the user that changes over time can be made possible in an advantageous manner.

Erfindungsgemäß erfasst die Steuerung eine Beladung des Behandlungsbereichs, wobei die Steuerung die Dosiereinrichtung in Abhängigkeit von zumindest dem Behandlungsmittelparameter und der erfassten Beladung des Behandlungsbereichs entsprechend dem ausgewählten Behandlungsprogramm ansteuert.According to the invention, the controller detects a loading of the treatment area, the controller activating the metering device as a function of at least the treatment agent parameter and the detected loading of the treatment area in accordance with the selected treatment program.

Vorteilhaft ist es auch, dass ein von dem Benutzer einstellbarer Behandlungsmittelparameter eine Behandlungsmittelmenge ist. Hierbei ist es ferner erfindungsgemäß, dass die Steuerung eine Behandlungsmittelbasismenge für die Behandlungsmittelmenge vorgibt und dass die Steuerung zum Einstellen der Behandlungsmittelmenge eine relative oder absolute Erhöhung oder Verringerung der Behandlungsmittelmenge ausgehend von der vorgegebenen Behandlungsmittelbasismenge ermöglicht. Hierbei kann in vorteilhafter Weise in der Anzeigeeinrichtung der momentan eingestellte Wert für die Behandlungsmittelmenge als absolute oder relative Größe angezeigt werden. Beispielsweise kann die Behandlungsmittelmenge relativ in Bezug auf die Behandlungsmittelbasismenge in Prozent angezeigt werden. Ausgehend von 100% kann der Benutzer dann beispielsweise eine Behandlungsmittelmenge von 120% der Behandlungsmittelbasismenge einstellen. Hierdurch ist eine einfache Bedienbarkeit gewährleistet.It is also advantageous that a treatment agent parameter that can be set by the user is an amount of treatment agent. Here, it is also according to the invention that the controller specifies a basic amount of treatment agent for the amount of treatment agent and that the controller for setting the amount of treatment agent enables a relative or absolute increase or decrease in the amount of treatment agent based on the predetermined amount of treatment agent. Here, the currently set value for the amount of treatment agent can advantageously be displayed as an absolute or relative variable in the display device. For example, the amount of treatment agent can be displayed in percent relative to the base amount of treatment agent. Starting from 100%, the user can then, for example, set an amount of treatment agent of 120% of the base amount of treatment agent. This ensures simple operability.

Somit können in vorteilhafter Weise Ressourcen geschont werden. Hierbei kann auch eine minimale Behandlungsmittelmenge vorgegeben werden, um die Ressource Waschmittel zu schonen. Für die Erhöhung oder Verringerung der Behandlungsmittelmenge ist vorzugsweise ein gewisser Bereich vorgegeben, um unerwünschte Über- oder Unterdosierungen zu verhindern und insbesondere zuverlässig ein erfolgreiches Behandlungsergebnis zu erzielen.Resources can thus be saved in an advantageous manner. A minimum amount of treatment agent can also be specified in order to conserve the detergent resource. A certain range is preferably specified for increasing or reducing the amount of treatment agent in order to prevent undesired overdosing or underdosing and in particular to reliably achieve a successful treatment result.

Das wasserführende Hausgerät 1 kann insbesondere als Wäschebehandlungsgerät ausgestaltet sein und zum Waschen sowie gegebenenfalls zum Trocknen von Wäsche dienen. Speziell kann das wasserführende Hausgerät 1 als Waschmaschine oder Waschtrockner ausgestaltet sein. Das wasserführende Hausgerät 1 eignet sich in entsprechend angepasster Abwandlung allerdings auch für andere Anwendungsfälle, insbesondere kann es als Geschirrspüler ausgestaltet sein. Fig. 1 shows a water-bearing domestic appliance 1 in a partial, schematic representation according to an embodiment. The water-bearing domestic appliance 1 can in particular be designed as a laundry treatment appliance and can be used for washing and, if necessary, drying laundry. The water-bearing domestic appliance 1 can specifically be designed as a washing machine or washer-dryer. The water-bearing domestic appliance 1 is, however, also suitable in a correspondingly adapted modification for other applications, in particular it can be designed as a dishwasher.

Das wasserführende Hausgerät 1 weist eine Frischwasserleitung 2 auf, die an einem Anschluss 3 mit einem Rohrsystem einer Hausinstallation oder dergleichen verbunden werden kann. In der Frischwasserleitung 2 ist ein Sperrventil 4 angeordnet. Hierbei weist das wasserführende Hausgerät 1 eine Steuerung 5 auf, die das Sperrventil 4 entsprechend einem Programmablauf eines Behandlungsprogramms ansteuert. Bei geöffnetem Sperrventil 4 fließt Frischwasser aus der Frischwasserleitung 2 über eine freie Luftstrecke in einen Einspülbehälter 6.The water-carrying household appliance 1 has a fresh water line 2 which can be connected at a connection 3 to a pipe system of a house installation or the like. A shut-off valve 4 is arranged in the fresh water line 2. Here, the water-bearing domestic appliance 1 has a controller 5 which controls the shut-off valve 4 in accordance with a program sequence of a treatment program. When the shut-off valve 4 is open, fresh water flows from the fresh water line 2 via a free air path into a induction bowl 6.

Das wasserführende Hausgerät 1 weist außerdem eine Dosiereinrichtung 7 mit einer oder mehreren Dosierpumpen 8, 9 auf. In diesem Ausführungsbeispiel sind zur Vereinfachung der Darstellung zwei Dosierpumpen 8, 9 dargestellt. Die Dosiereinrichtung 7 dient zum Fördern eines oder mehrerer Behandlungsmittel aus einem Behandlungsmittelbehälter 10 über eine oder mehrere Leitungen 11, 12 in den Einspülbehälter 6. In diesem Ausführungsbeispiel weist der Behandlungsmittelbehälter 10 Kammern 13, 14 auf, die mit unterschiedlichen Behandlungsmitteln von einem Benutzer aufgefüllt werden können. Dabei bevorraten die Kammern 13 oder 14 des Behandlungsmittelbehälters 10 jeweils eine größere Menge an dem eingefüllten Behandlungsmittel, so dass für mehrere Programmdurchführungen ausreichende Behandlungsmittel bereitgestellt sind. Die Dosiereinrichtung 7 dient hierbei zum Zumessen der jeweils für das Programm erforderlichen Mengen an Wäschebehandlungsmitteln.The water-bearing domestic appliance 1 also has a metering device 7 with one or more metering pumps 8, 9. In this embodiment, two metering pumps 8, 9 are shown to simplify the illustration. The metering device 7 serves to convey one or more treatment agents from a treatment agent container 10 via one or more lines 11, 12 into the induction bowl 6. In this embodiment, the treatment agent container 10 has chambers 13, 14 that can be filled with different treatment agents by a user . In this case, the chambers 13 or 14 of the treatment agent container 10 each store a larger amount of the treatment agent filled in, so that sufficient treatment agents are provided for several program executions. The The metering device 7 serves to meter the quantities of laundry treatment agents required in each case for the program.

Die von der Dosiereinrichtung 7 in den Einspülbehälter 6 geförderten Behandlungsmittel werden von dem durch den Einspülbehälter 6 laufenden Frischwasser über einen Verbindungsstutzen 15 in einen Behandlungsbereich 16 des wasserführenden Hausgeräts 1 gespült. In diesem Ausführungsbeispiel ist der Behandlungsbereich 16 zumindest im Wesentlichen von einem Laugenbehälter 17 umgeben. Ein Ausgang des Laugenbehälters 17 ist mit einer Abflussleitung 18 verbunden, die an einem Ausgang 19 des wasserführenden Hausgeräts 1 mit einer Abwasserleitung der Hausinstallation oder dergleichen verbindbar ist. Hierbei ist in der Abflussleitung 18 eine Laugenpumpe 20 angeordnet, die von der Steuerung 5 entsprechend dem Programmablauf angesteuert wird, um eine Lauge oder dergleichen aus dem Behandlungsbereich 16 abzupumpen.The treatment agents conveyed by the dosing device 7 into the induction bowl 6 are flushed by the fresh water flowing through the induction bowl 6 via a connecting piece 15 into a treatment area 16 of the water-carrying domestic appliance 1. In this exemplary embodiment, the treatment area 16 is at least essentially surrounded by a tub 17. An outlet of the tub 17 is connected to a drain line 18, which can be connected at an outlet 19 of the water-bearing domestic appliance 1 to a sewer pipe of the domestic installation or the like. In this case, a lye pump 20 is arranged in the drain line 18, which is activated by the controller 5 in accordance with the program sequence in order to pump a lye or the like out of the treatment area 16.

Das wasserführende Hausgerät 1 weist eine Anzeigeeinrichtung 25 und eine Eingabeeinrichtung 26 mit Tastelementen 27, 28, 29, 30 auf. Hierbei können die Anzeigeeinrichtung 25 und die Eingabeeinrichtung 26 auch durch eine kombinierte Anzeige- und Eingabeeinrichtung 25, 26 realisiert sein. Die Anzeigeeinrichtung 25 und die Eingabeeinrichtung 26 sind mit der Steuerung 5 verbunden. Die Steuerung ist außerdem mit einem Speicherelement 31 verbunden, das zum Speichern veränderbarer Parameter dient.The water-bearing domestic appliance 1 has a display device 25 and an input device 26 with touch elements 27, 28, 29, 30. Here, the display device 25 and the input device 26 can also be implemented by a combined display and input device 25, 26. The display device 25 and the input device 26 are connected to the controller 5. The control is also connected to a memory element 31 which is used to store changeable parameters.

Die Steuerung 5 weist mehrere Behandlungsprogramme auf. Hierbei bietet die Steuerung 5 einem Benutzer die Auswahl eines der Behandlungsprogramme aus den mehreren Behandlungsprogrammen an. Hierbei wird in der Anzeigeeinrichtung 25 ein mögliches Behandlungsprogramm angezeigt, wobei über die Tastelemente 27, 28 der Eingabeeinrichtung 26 eine Änderung des Behandlungsprogramms durch den Benutzer möglich ist. Speziell kann ein Benutzer ein Waschprogramm für Feinwäsche, ein Waschprogramm für Buntwäsche oder ein Waschprogramm für Kochwäsche auswählen. Solch einem Waschprogramm kann eine bestimmte Waschtemperatur und ein bestimmter Behandlungsmitteltyp, beispielsweise ein Vollwaschmittel, ein Feinwaschmittel, ein Vollwaschmittelkonzentrat, ein Feinwaschmittelkonzentrat, ein Buntwaschmittel oder ein Buntwaschmittelkonzentrat, zugeordnet sein. Ein Beispiel ist ein Programm für Feinwäsche, dem eine Waschtemperatur von 30°C und ein Feinwaschmittel zugeordnet sein kann.The controller 5 has several treatment programs. In this case, the controller 5 offers a user the choice of one of the treatment programs from the multiple treatment programs. In this case, a possible treatment program is displayed in the display device 25, with the user being able to change the treatment program via the touch elements 27, 28 of the input device 26. In particular, a user can select a washing program for delicates, a washing program for coloreds or a washing program for whites. Such a washing program can be assigned a specific washing temperature and a specific type of treatment agent, for example a heavy duty detergent, a mild detergent, a heavy duty detergent concentrate, a mild detergent concentrate, a colored detergent or a colored detergent concentrate. An example is a program for Delicates, which can be assigned a washing temperature of 30 ° C and a mild detergent.

Nach der Auswahl des Behandlungsprogramms durch den Benutzer können noch ein oder mehrere Behandlungsmittelparameter eingestellt werden. Die Einstellung der Behandlungsmittelparameter erfolgt vorzugsweise durch eine Auswahl des gewünschten Behandlungsmittelparameters aus einer vorgegebenen Liste oder aus einem vorgegebenen Bereich. Speziell kann die Steuerung 5 einen bestimmten Wert für den Behandlungsmittelparameter vorgeben, der von dem gewählten Behandlungsprogramm abhängen kann. Dieser vorgegebene Behandlungsmittelparameter kann dem Benutzer durch die Anzeigeeinrichtung 25 angezeigt werden. Beispielsweise ist durch das gewählte Behandlungsprogramm ein Behandlungsmitteltyp vorgegeben. Bei der Auswahl eines Programms für Feinwäsche ist beispielsweise ein Feinwaschmittel als Behandlungsmitteltyp vorgegeben. Diesen Programmparameter, nämlich den Behandlungsmitteltyp Feinwaschmittel, kann der Benutzer durch die Tastelemente 29, 30 abändern. Hierdurch kann der Benutzer beispielsweise anstelle des Feinwaschmittels ein Buntwaschmittel als Behandlungsmitteltyp für das gewählte Behandlungsprogramm auswählen. Nach der möglichen Einstellung weiterer Behandlungsmittelparameter wird dann das Behandlungsprogramm, beispielsweise das Programm für Feinwäsche, mit dem gewählten Behandlungsmitteltyp, beispielsweise dem Buntwaschmittel, durchgeführt.After the selection of the treatment program by the user, one or more treatment agent parameters can also be set. The treatment agent parameters are preferably set by selecting the desired treatment agent parameter from a predefined list or from a predefined range. In particular, the controller 5 can predetermine a specific value for the treatment agent parameter, which can depend on the selected treatment program. This predetermined treatment agent parameter can be displayed to the user by the display device 25. For example, a treatment agent type is predetermined by the selected treatment program. When selecting a program for delicates, for example, a mild detergent is specified as the type of treatment agent. The user can change this program parameter, namely the type of treatment agent for mild detergents, using the tactile elements 29, 30. As a result, the user can, for example, instead of the mild detergent, select a colored detergent as the treatment agent type for the selected treatment program. After the possible setting of further treatment agent parameters, the treatment program, for example the program for delicates, is then carried out with the selected treatment agent type, for example the colored detergent.

Die Steuerung 5 führt das ausgewählte Behandlungsprogramm aus. Hierbei steuert die Steuerung 5 unter anderem die Dosiereinrichtung 7 entsprechend dem ausgewählten Behandlungsprogramm an. Die Steuerung 5 berücksichtigt bei der Ausführung des ausgewählten Behandlungsprogramms die von dem Benutzer eingestellten Behandlungsmittelparameter, die gegebenenfalls gegenüber vorgegebenen Behandlungsmittelparametern geändert sind.The controller 5 executes the selected treatment program. Here, the controller 5 controls, among other things, the metering device 7 in accordance with the selected treatment program. When executing the selected treatment program, the controller 5 takes into account the treatment agent parameters set by the user, which may have been changed with respect to predetermined treatment agent parameters.

Beispielsweise kann durch einen Behandlungsmittelparameter, der ein Behandlungsmitteltyp ist, während des Programmablaufs ein bestimmtes Behandlungsmittel vorgegeben sein. Beispielsweise ist bei der Ausführung eines Programms für Feinwäsche in der Regel als Behandlungsmitteltyp für das Waschmittel ein Feinwaschmittel vorgegeben, so dass die Steuerung 5 die Dosiereinrichtung 7 zum Zumessen des Feinwaschmittels ansteuert. Ist hingegen anstelle des Feinwaschmittels durch den Benutzer ein anderer Behandlungsmitteltyp, beispielsweise ein Buntwaschmittel, eingestellt worden, dann steuert die Steuerung 5 die Dosiereinrichtung 7 zum Zumessen des Buntwaschmittels anstelle des Feinwaschmittels an.For example, a specific treatment agent can be specified during the program sequence by a treatment agent parameter that is a treatment agent type. For example, when executing a program for delicates, a mild detergent is usually specified as the treatment agent type for the detergent, so that the controller 5 controls the metering device 7 for metering the mild detergent. Is instead of the mild detergent If another type of treatment agent has been set by the user, for example a colored detergent, then the controller 5 controls the metering device 7 for metering the colored detergent instead of the mild detergent.

Beispielsweise kann die Kammer 13 zum Aufnehmen von Buntwaschmittel dienen, während die Kammer 14 zum Aufnehmen von Feinwaschmittel dient. Durch Ansteuerung entweder der Dosierpumpe 8 oder der Dosierpumpe 9 der Dosiereinrichtung 7 wird dann entsprechend dem von dem Benutzer eingestellten Behandlungsmitteltyp das Feinwaschmittel oder das Buntwaschmittel zugemessen.For example, the chamber 13 can be used to hold colored detergent, while the chamber 14 is used to hold mild detergent. By controlling either the metering pump 8 or the metering pump 9 of the metering device 7, the mild detergent or the colored detergent is then metered according to the type of treatment agent set by the user.

Beispielsweise kann der Benutzer stark verschmutzte, aber temperaturempfindliche Feinwäsche in den Behandlungsbereich 16 einfüllen. Durch Auswählen des Programms für Feinwäsche und Änderung des Behandlungsmitteltyps von Feinwaschmittel auf Buntwaschmittel kann dann während des Programmablaufs eine erhöhte Reinigungswirkung erzielt werden.For example, the user can pour heavily soiled but temperature-sensitive delicates into the treatment area 16. By selecting the program for delicates and changing the treatment agent type from mild detergent to colored detergent, an increased cleaning effect can be achieved during the program sequence.

Ein weiterer möglicher Behandlungsmittelparameter, der von dem Benutzer eingestellt werden kann, ist eine Behandlungsmittelmenge. Hierbei kann die Steuerung 5 eine Behandlungsmittelbasismenge für jedes der bevorrateten Behandlungsmittel vorgeben. Die Behandlungsmittelbasismenge kann hierbei vom ausgewählten Behandlungsprogramm abhängen. Über die Tastelemente 29, 30 kann die in der Anzeigeeinrichtung 25 angezeigte, vorgegebene Behandlungsmittelmenge erhöht oder verringert werden. Hierbei ist eine relative oder absolute Erhöhung oder Verringerung möglich. Beispielsweise kann die Anzeigeeinrichtung 25 die Behandlungsmittelmenge als Absolutwert in einer Volumeneinheit, insbesondere in Milliliter, anzeigen. Die Anzeigeeinrichtung 25 kann die Behandlungsmittelmenge auch in Prozent der Behandlungsmittelbasismenge anzeigen. Dies ermöglicht eine intuitive Bedienung durch den Benutzer. Somit kann der Benutzer je nach Verschmutzungsgrad eine Erhöhung oder Verringerung der Behandlungsmittelmenge vornehmen.Another possible treatment agent parameter that can be set by the user is an amount of treatment agent. In this case, the controller 5 can specify a basic amount of treatment agent for each of the stored treatment agents. The basic amount of treatment agent can depend on the selected treatment program. The predetermined amount of treatment agent displayed in the display device 25 can be increased or decreased via the feeler elements 29, 30. A relative or absolute increase or decrease is possible here. For example, the display device 25 can display the amount of treatment agent as an absolute value in a volume unit, in particular in milliliters. The display device 25 can also display the amount of treatment agent as a percentage of the base amount of treatment agent. This enables intuitive operation by the user. The user can thus increase or decrease the amount of treatment agent depending on the degree of contamination.

Während des Programmablaufs des von dem Benutzer gewählten Behandlungsprogramms steuert die Steuerung 5 dann die Dosiereinrichtung 7 so an, dass die von dem Benutzer eingestellten und gegebenenfalls von den Behandlungsmittelbasismengen abweichenden Behandlungsmittelmengen des jeweiligen Behandlungsmittels zugemessen werden. Hierbei können sich die Behandlungsmittelmengen sowie die Behandlungsmittelbasismengen auf bestimmte Beladungen des Behandlungsbereichs 16, beispielsweise auf eine Beladung von 5 kg Textilien, beziehen. Die tatsächliche Beladung des Behandlungsbereichs 16 mit Textilien kann dann am Anfang des Programmablaufs erfasst werden. Die Steuerung 5 kann dann die Dosiereinrichtung 7 in Abhängigkeit von sowohl den Behandlungsmittelparametern als auch der erfassten Beladung des Behandlungsbereichs 16 entsprechend dem ausgewählten Behandlungsprogramm ansteuern. Möglich ist es hierbei auch, dass die aktuelle Beladung des Behandlungsbereichs 16 bereits beim Anzeigen der Behandlungsmittelbasismenge durch die Anzeigeeinrichtung 25 berücksichtigt wird. Hierdurch kann der Benutzer die für die Textilien im Behandlungsbereich 16 vorgesehene Behandlungsmittelmenge direkt ablesen und gegebenenfalls auf den gewünschten Wert abändern.During the program sequence of the treatment program selected by the user, the controller 5 then controls the metering device 7 in such a way that the treatment agent quantities of the respective treatment agent set by the user and possibly deviating from the treatment agent base quantities Treatment agent are apportioned. The amounts of treatment agent and the base amounts of treatment agent can relate to specific loads of the treatment area 16, for example to a load of 5 kg of textiles. The actual loading of the treatment area 16 with textiles can then be recorded at the beginning of the program sequence. The controller 5 can then control the metering device 7 as a function of both the treatment agent parameters and the detected loading of the treatment area 16 in accordance with the selected treatment program. It is also possible here for the current loading of the treatment area 16 to be taken into account when the display device 25 displays the basic amount of treatment agent. In this way, the user can directly read off the amount of treatment agent provided for the textiles in the treatment area 16 and, if necessary, change it to the desired value.

Die Benutzerfreundlichkeit des wasserführenden Hausgeräts 1 kann durch Anzeigen charakteristischer Programmeigenschaften des ausgewählten Behandlungsprogramms weiter verbessert werden. Speziell ergibt sich eine benutzerfreundliche Ausgestaltung, wenn während der Einstellung der Behandlungsmittelparameter durch den Benutzer eine Anzeige dieser charakteristischen Programmeigenschaften erfolgt. Hierbei werden in der Anzeigeeinrichtung 25 eine oder mehrere charakteristische Programmeigenschaften des ausgewählten Behandlungsprogramms angezeigt, die von den zu verstellenden Behandlungsmittelparametern abhängen. Beim Ändern der Behandlungsmittelparameter erfolgt eine fortlaufende Aktualisierung durch die Steuerung 5. Hierbei bestimmt die Steuerung 5 die charakteristischen Programmeigenschaften in Abhängigkeit von den geänderten Behandlungsmittelparametern.The user friendliness of the water-bearing domestic appliance 1 can be further improved by displaying characteristic program properties of the selected treatment program. In particular, a user-friendly configuration results if these characteristic program properties are displayed while the treatment agent parameters are being set by the user. Here, one or more characteristic program properties of the selected treatment program are displayed in the display device 25, which are dependent on the treatment agent parameters to be adjusted. When the treatment agent parameters are changed, the controller 5 continuously updates them. Here, the controller 5 determines the characteristic program properties as a function of the changed treatment agent parameters.

Charakteristische Programmeigenschaften, die von der Anzeigeeinrichtung 25 angezeigt werden, sind beispielsweise eine erwartete Programmdauer, ein erwarteter Energiebedarf, ein erwarteter Wasserbedarf und ein erwarteter Behandlungsmittelparameter, wobei erfindungsgemäß zumindest die erwartete Programmdauer, der erwartete Energiebedarf oder der erwartete Wasserbedarf angezeigt werden.Characteristic program properties that are displayed by the display device 25 are, for example, an expected program duration, an expected energy requirement, an expected water requirement and an expected treatment agent parameter, with at least the expected program duration, the expected energy requirement or the expected water requirement being displayed according to the invention.

Verändert beispielsweise ein Benutzer den Behandlungsmittelparameter Behandlungsmittelmenge, dann wirkt sich dies auf die erwartete Programmdauer aus. Da die Steuerung 5 die erwartete Programmdauer in Abhängigkeit von der Behandlungsmittelmenge neu bestimmt und der aktualisierte Wert für die erwartete Programmdauer in der Anzeigeeinrichtung 25 angezeigt wird, kann der Benutzer die Auswirkung seiner Auswahl auf den Programmablauf direkt erkennen. Somit kann ein Benutzer beispielsweise durch Erhöhen der Behandlungsmittelmenge die Programmdauer verkürzen.If, for example, a user changes the treatment agent parameter, treatment agent quantity, this affects the expected program duration. Since the controller 5 redetermines the expected program duration as a function of the amount of treatment agent and the updated value for the expected program duration is displayed in the display device 25, the user can see the Recognize the effect of your selection on the program flow directly. Thus, a user can shorten the program duration, for example by increasing the amount of treatment agent.

Somit hat der Benutzer die Möglichkeit, in verschiedener Weise auf die durchzuführende Behandlung der Textilien im Behandlungsbereich 16 einzuwirken. Hierbei kann der Benutzer die zuzuführende Waschmittelmenge und die Waschmittelart beeinflussen. Ferner kann hierbei auch die Waschmechanik, eine Wassermenge, eine Temperaturführung und eine Programmdauer beeinflusst werden. Ferner kann durch Wahl des Waschmitteltyps, beispielsweise eines konzentrierten oder normalen Waschmittels, eines Vollwaschmittels oder eines Feinwaschmittels, ebenfalls Einfluss auf den Programmablauf genommen werden. So kann der Benutzer durch Wahl des Waschmitteltyps beispielsweise eine an das Vorhandensein von Bleiche optimierte Programmgestaltung aktivieren oder deaktivieren. Entsprechendes gilt auch für andere, in den unterschiedlichen Waschmitteltypen vorhandene Inhaltsstoffe.The user thus has the possibility of influencing the treatment to be carried out on the textiles in the treatment area 16 in various ways. The user can influence the amount of detergent to be added and the type of detergent. The washing mechanics, the amount of water, a temperature control and the duration of the program can also be influenced. Furthermore, by choosing the type of detergent, for example a concentrated or normal detergent, a heavy duty detergent or a mild detergent, you can also influence the program sequence. For example, by selecting the type of detergent, the user can activate or deactivate a program configuration optimized for the presence of bleach. The same applies to other ingredients present in the different types of detergent.

Speziell kann der Benutzer eine besonders kurze Waschzeit bei erhöhtem Waschmitteleinsatz oder eine besonders sparsame, aber längere Waschzeit des Waschprogramms bei geringerem Waschmitteleinsatz erzielen. Die tatsächliche Waschmittelzugabe erfolgt hierbei in vorteilhafter Weise durch die Dosiereinrichtung 7, wodurch eine Über- oder Unterdosierung vermieden ist. Hierbei kann die tatsächlich zugemessene Menge der Wäschebehandlungsmittel durch weitere von der Steuerung 5 berücksichtigte Größen beeinflusst sein, beispielsweise durch die Beladung des Behandlungsbereichs 16 oder eine Wasserhärte, die in dem Speicherelement 31 eingestellt sein kann.In particular, the user can achieve a particularly short washing time with an increased use of detergent or a particularly economical but longer washing time of the washing program with less use of detergent. The actual detergent addition takes place here in an advantageous manner by the metering device 7, as a result of which overdosing or underdosing is avoided. Here, the actually metered amount of laundry treatment agents can be influenced by further variables taken into account by the controller 5, for example by the loading of the treatment area 16 or a water hardness that can be set in the storage element 31.

Über die Anzeigeeinrichtung 25 und die Eingabeeinrichtung 26 kann eine benutzerfreundliche Dialogfunktion mit einer Benutzerführung realisiert sein. Hierbei kann in vorteilhafter Weise durch voreingestellte oder durch die Steuerung 5 bestimmte Empfehlungen eine einfache Bedienung erreicht werden. Hierbei kann der Benutzer selbst entscheiden, ob er die vorgegebene Empfehlung für die Behandlungsmittelparameter des ausgewählten Behandlungsprogramms abändern möchte oder nicht.A user-friendly dialog function with user guidance can be implemented via the display device 25 and the input device 26. In this case, simple operation can advantageously be achieved by means of preset recommendations or recommendations determined by the controller 5. The user can decide for himself whether he would like to change the given recommendation for the treatment agent parameters of the selected treatment program or not.

Außerdem kann dem Benutzer auch eine vereinfachte Einstellung ermöglicht werden. Beispielsweise kann die Einstellung des Behandlungsmittelparameters beziehungsweise der Behandlungsmittelparameter auch über vereinfachte Auswahloptionen erfolgen. Hierbei kann dem Benutzer zum Einstellen des oder der Behandlungsmittelparameter in der Anzeigeeinrichtung 25 in Bezug auf die Behandlungsmittel eine Auswahl zwischen "sparsam", "normal" und "schnell" gegeben werden. Wählt der Benutzer beispielsweise die Option "sparsam", dann kann eine Programmdurchführung mit einer reduzierten Behandlungsmittelmenge, mit weniger Energie und weniger Frischwasser bei einer entsprechend längeren Programmdauer durchgeführt werden. Wählt der Benutzer hingegen die Option "schnell", dann kann die Programmdurchführung mit einer erhöhten Behandlungsmittelmenge, mit mehr Energie und mit einer größeren Frischwasserzufuhr erfolgen, wodurch die Programmdauer reduziert ist.In addition, the user can also be given a simplified setting. For example, the setting of the treatment agent parameter or the treatment agent parameters can also take place via simplified selection options. Here, the user can be given a choice between “economical”, “normal” and “fast” for setting the treatment agent parameter (s) in the display device 25 in relation to the treatment agent. If the user selects the “economical” option, for example, then a program can be carried out with a reduced amount of treatment agent, with less energy and less fresh water, with a correspondingly longer program duration. If, on the other hand, the user selects the “fast” option, the program can be carried out with an increased amount of treatment agent, with more energy and with a larger supply of fresh water, which reduces the duration of the program.

In Abhängigkeit von den gewählten Behandlungsmittelparametern kann das Behandlungsprogramm auch in anderer Hinsicht beeinflusst werden. Beispielsweise kann durch die Art des gewählten Behandlungsmitteltyps auch die Temperaturführung beeinflusst werden. Beispielsweise kann für ein Bleichmittel oder den Bestandteil einer Bleiche in einem Waschmittel eine längere Heizperiode erforderlich sein. Auch kann dies eine andere Waschmechanik bedingen. Die Waschtemperatur wird allerdings vorzugsweise nicht verändert, so dass das Programm mit der vorgegebenen oder durch den Benutzer eingestellten Waschtemperatur durchgeführt wird.Depending on the selected treatment agent parameters, the treatment program can also be influenced in other ways. For example, the temperature control can also be influenced by the type of treatment agent selected. For example, a bleach or a bleach ingredient in a laundry detergent may require a longer heating period. This can also require a different washing mechanism. However, the washing temperature is preferably not changed, so that the program is carried out with the washing temperature that is preset or that has been set by the user.

Somit kann speziell durch den Behandlungsmitteltyp und/oder die Behandlungsmittelmenge die Programmdauer durch den Benutzer beeinflusst werden.The program duration can thus be influenced by the user specifically through the type of treatment agent and / or the amount of treatment agent.

Die Erfindung ist nicht auf die beschriebenen Ausführungsbeispiele beschränkt.The invention is not restricted to the exemplary embodiments described.
