Description

Die Erfindung betrifft ein Verfahren zum Waschen von Wäsche in einer Waschmaschine mit einem Laugenbehälter zum Bevorraten von Waschflüssigkeit, in dem eine Trommel drehbar gelagert ist, mit den Phasen Waschen, in der zumindest eine vorgegebene Wassermenge in den Laugenbehälter eingelassen und auf eine vorgegebene Temperatur erwärmt wird, wobei die Phase Waschen zumindest einen oder mehrere zeitliche Abschnitte umfasst, die anhand von einem kombinierten Parametersatz, der einzelne Parameter enthält, die den Temperaturverlauf, die Behandlungsdauer und die Intensität der Trommeldrehung eines zeitlichen Abschnitts bestimmt, festgelegt wird, wobei der kombinierte Parametersatz mittels Parametern aus zumindest zwei spezifischen Parametersätzen erstellt wird, wobei die spezifischen Parametersätze jeweils für eine vom Benutzer ausgewählte spezifische Fleckenart bzw. Verschmutzungsart vorgesehen sind.The invention relates to a method for washing laundry in a washing machine with a tub for storing washing liquid, in which a drum is rotatably mounted, with the washing phases in which at least a predetermined amount of water is introduced into the tub and heated to a predetermined temperature wherein the washing phase comprises at least one or more temporal sections determined from a combined parameter set containing individual parameters that governs the temperature history, duration of treatment, and intensity of drum rotation of a time segment, the combined parameter set using parameters is created from at least two specific parameter sets, wherein the specific parameter sets are each provided for a user-selected specific Fleckenart or pollution type.

Zum Waschen von Wäsche in einer Waschmaschine wird die Wäsche in einer ersten Phase mit erwärmtem Wasser unter Zugabe von Waschmittel mit starker oder weniger starker Trommelbewegung bewegt. Dieser Behandlungsablauf führt zur Ablösung und Entfernung von Schmutz aus der Wäsche. Um eine gute Entfaltung des Waschmittels und eine gute Schmutzlösung zu erreichen, wird die Wäsche in der Regel für etwa 20 bis 30 Minuten in der Waschflüssigkeit bewegt, wobei abhängig von der zu waschenden Wäsche die Waschflüssigkeit auf eine vorbestimmte Temperatur erwärmt wird. Anhand des ausgewählten Waschprogramms und einiger optional wählbaren Zusatzparameter wird der Behandlungsablauf für die Wäsche festgelegt bzw. das in der Steuerung ablaufende Programm konfiguriert.For washing laundry in a washing machine, the laundry is moved in a first phase with heated water with the addition of detergent with strong or less strong drum motion. This treatment procedure leads to the detachment and removal of dirt from the laundry. In order to achieve a good development of the detergent and a good soil solution, the laundry is usually moved for about 20 to 30 minutes in the washing liquid, depending on the laundry to be washed, the washing liquid is heated to a predetermined temperature. Based on the selected wash program and some optionally selectable additional parameters, the treatment procedure for the laundry is defined or the program running in the controller is configured.

Für besonders hartnäckige Verschmutzungen bzw. zur Entfernung von Flecken wird eine besondere Behandlung benötigt. So ist es aus dem Dokument Hausgeräte Plus, Ausgabe Okt. 2002 bekannt, eine Zusatzfunktion für ein Waschprogramm bereitzustellen, die eine Entfernung von Flecken begünstigt. Bei dieser bekannten Funktion wird eine intensive Behandlung durch längere Waschdauer und ein dem Waschmittel optimiert angepasster Ablauf des Aufheizens der Waschflüssigkeit erreicht. Diese Maßnahme kann jedoch nur für bestimmte Flecken bzw. Verschmutzungsarten eine verbesserte Reinigungswirkung erzielen.For particularly stubborn dirt or to remove stains special treatment is needed. So it is from the Document Hausgeräte Plus, edition Oct. 2002 known to provide an additional function for a washing program that favors a removal of stains. In this known function, an intensive treatment is achieved by a longer washing time and an optimized washing of the optimized flow of heating the washing liquid. However, this measure can only achieve an improved cleaning effect for certain spots or types of soiling.

Aus der bereits verkauften Waschmaschine Siemens WM 16S740 ist es bekannt, zur Entfernung von Flecken das Waschprogramm anhand des zu entfernenden Fleckens optimal anzupassen. Der Benutzer wählt mit der Bedienhandhabe ein gewünschtes Waschprogramm aus und kann als Option eine Fleckenbehandlung hinzuzählen. Hierbei kann aus einer Vielzahl von Verschmutzungsarten oder Fleckenarten eine Fleckenart ausgewählt werden, wodurch das ausgewählte Waschprogramm hinsichtlich der geeigneten Parameter zur ausgewählten Fleckenentfernung angepasst wird. Diese Möglichkeit hat den Vorteil, dass die zu entfernende Verschmutzung nicht im Gewebe der Wäsche fixiert wird, wenn die sonst übliche einheitliche Fleckenoption so etwas verursachen würde. Für den Fall, dass Wäschestücke mit unterschiedlichen Fleckarten oder Verschmutzungsarten optimal gewaschen werden sollen, sind mehrere Waschgänge durchzuführen, da das Waschprogramm nur auf eine einzige Fleckenart angepasst werden kann.From the already sold washing machine Siemens WM 16S740 it is known to adjust the removal of stains the washing program on the basis of the stain to be removed. The user selects a desired washing program with the operating handle and can optionally add stain treatment. Hereby, one type of speckle can be selected from a variety of types of soiling or types of stains, thereby tailoring the selected washing program for the appropriate stain removal parameter. This possibility has the advantage that the dirt to be removed is not fixed in the fabric of the laundry, if the usual uniform stain option would cause something like this. In the event that items of laundry with different types of stains or types of contamination are to be washed optimally, several washes must be carried out, since the washing program can only be adapted to a single type of stain.

Eine Waschmaschine, die ein ähnliches Verfahren bereitstellt, ist aus der US 2003/0154560 A1 bekannt.A washing machine that provides a similar method is out of the US 2003/0154560 A1 known.

Die US 2008/0276655 A1 beschreibt ein Verfahren der eingangs genannten Art.The US 2008/0276655 A1 describes a method of the type mentioned.

Der Erfindung liegt deshalb die Aufgabe zu Grunde, ein Verfahren zum Waschen von Wäsche mit der Möglichkeit zur Entfernung von Flecken oder hartnäckigen Verschmutzungsarten in einem Waschgang zu verbessern.The invention is therefore based on the object to improve a method for washing laundry with the ability to remove stains or stubborn soiling in a wash cycle.

Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungen ergeben sich aus den abhängigen Ansprüchen.The object is achieved by a method having the features of claim 1. Advantageous embodiments will be apparent from the dependent claims.

Der wesentliche Vorteil des erfindungsgemäßen Verfahrens ist, dass eine zuverlässige Entfernung von unterschiedlichen Fleckenarten in einem einzigen Waschgang erreicht wird. Ferner wird dem Benutzer eine einfache und übersichtliche Möglichkeit zum Konfigurieren des Waschprogramms bereitgestellt, wobei das Waschprogramm hinsichtlich des Ablaufs und der Parameter durch die Auswahl der Fleckenarten konfiguriert wird.The main advantage of the method according to the invention is that a reliable removal of different types of stains is achieved in a single wash cycle. Furthermore, the user is provided with a simple and clear possibility for configuring the wash program, wherein the wash program is configured with regard to the sequence and the parameters by selecting the types of stains.

Beim erfindungsgemäßen Verfahren umfasst die Phase Waschen zumindest einen oder mehrere zeitliche Abschnitte, die anhand von einem kombinierten Parametersatz, der einzelne Parameter enthält, die den Temperaturverlauf, die Behandlungsdauer und die Intensität der Trommeldrehung eines zeitlichen Abschnitts bestimmt, festgelegt wird. Der kombinierte Parametersatz wird mittels Parametern aus spezifischen Parametersätzen erstellt, wobei die spezifischen Parametersätze jeweils für eine spezifische Fleckenart bzw. Verschmutzungsart vorgesehen sind. Auf diese Weise wird die Phase Waschen abhängig von mehreren ausgewählten Verschmutzungsarten bzw. Fleckenarten hinsichtlich ihrer Abfolge und Parameter, die das Verhalten der Heizung, den Wasserstand und die Trommelbewegung bestimmen, zusammengestellt bzw. konfiguriert. Die Verschmutzungsarten können mit Hilfe einer Bedienhandhabe der Steuerung zugeführt werden, so dass anhand dieser Information die Zusammenstellung der Parameter für den abzulaufenden Programmteil erfolgt. Es wird der kombinierte Parametersatz aus zumindest zwei spezifischen Parametersätzen erstellt, so dass der Benutzer zumindest zwei unterschiedlich Fleckenarten auswählen bzw. einstellen kann, die aus der Wäsche entfernt werden sollen. Somit werden die einzelnen zeitlichen Phasen anhand der Parameter so erstellt, dass in der Waschphase für die ausgewählten Flecken das optimale Reinigungsergebnis erzielt wird. In weiteren Ausführungen sind auch mehr als zwei unterschiedliche Fleckenarten auswählbar, wobei die Zusammenstellung der zeitlichen Abschnitte entsprechend erfolgt. Außerdem ist jedem Parameter in dem jeweiligen spezifischen Parametersatz eine Rangkennung zugeordnet, die festlegt, aus welchem spezifischen Parametersatz der in den kombinierten Parametersatz einzutragende Parameter übernommen wird. Dadurch werden aus mehreren Parametersätzen nur die höchstrangigen Parameter in den kombinierten Parametersatz aufgenommen, die entsprechenden Parameter mit niedrigerem Rang aus anderen spezifischen Parametersätzen werden dann entsprechend nicht in den kombinierten Parametersatz übernommen. Dadurch wird eine Aneinanderreihung der zeitlichen Abschnitte vermieden, so dass sich die Dauer der Waschphase nicht so sehr erhöht, wenn mehrere unterschiedliche Fleckenarten oder Verschmutzungsarten ausgewählt werden.In the method according to the invention, the washing phase comprises at least one or more temporal sections determined on the basis of a combined parameter set containing individual parameters which determines the temperature profile, the duration of treatment and the intensity of drum rotation of a temporal section. The combined parameter set is created by means of parameters from specific parameter sets, the specific parameter sets being provided in each case for a specific type of stain or type of soiling. In this way, the washing phase is compiled or configured depending on several selected types of soils or types of stains with regard to their sequence and parameters that govern the behavior of the heater, water level and drum movement. The types of contamination can be supplied by means of an operating handle of the controller, so that based This information is the compilation of the parameters for the program part to be run. The combined parameter set is created from at least two specific parameter sets so that the user can select or set at least two different types of stains to be removed from the laundry. Thus, the individual time phases are created based on the parameters so that the optimum cleaning result is achieved in the washing phase for the selected spots. In further embodiments, more than two different types of stains are selectable, the compilation of the temporal sections is carried out accordingly. In addition, each parameter in the respective specific parameter set is assigned a rank identifier which determines from which specific parameter set the parameter to be entered into the combined parameter set is taken. As a result, only the highest-ranking parameters are included in the combined parameter set from several parameter sets, the corresponding lower-ranking parameters from other specific parameter sets are then not correspondingly adopted in the combined parameter set. This avoids a juxtaposition of the temporal sections, so that the duration of the washing phase does not increase so much when several different types of stains or types of soiling are selected.

Hierbei ist es zweckmäßig, dass der kombinierte Parametersatz für jeweils einen zeitlichen Abschnitt den/die Parameter mit dem jeweils höchsten Rang erhält, so dass die zeitlichen Abschnitte für das Entfernen aller ausgewählten Fleckenarten bzw. Verschmutzungsarten geeignet sind. Auf diese Weise wird sichergestellt, dass die zeitlichen Abschnitte so zusammengestellt werden, dass alle ausgewählten Flecken aus den Fasern der Wäsche optimal gelöst und entfernt werden, ohne dass es zu einer Fixierung einer Fleckenart kommt, wenn sie beispielsweise zu Beginn der Waschphase mit falschen Parametern behandelt wurde.In this case, it is expedient for the combined parameter set to receive the parameter (s) with the respectively highest rank for one temporal section in each case, so that the time segments are suitable for removing all selected types of stain or types of contamination. In this way it is ensured that the temporal sections are assembled in such a way that all selected spots of the fibers of the laundry are optimally loosened and removed without there being any fixation of a stain type, for example if it is treated with incorrect parameters at the beginning of the washing phase has been.

Insgesamt ist es zweckmäßig, für einen zeitlichen Abschnitt jeweils eine Dauer von etwa 6 bis 30 Min vorzusehen, wobei die Dauer anhand des jeweils vorgesehenen Parameters im kombinierten Parametersatz festgelegt ist. Diese Behandlungszeiten, in denen die Wäsche in der Waschflüssigkeit bewegt und die Waschflüssigkeit anhand der Parameter erwärmt wird, sind einerseits lang genug, um die hartnäckige Verschmutzung zu lösen und aus der Wäsche zu entfernen und andererseits nicht zu lang, dass die gesamte Waschphase zu lang wird und evtl. Rückverschmutzungen auftreten können, wenn der gelöste Schmutz in anderen in der Waschflüssigkeit befindlichen Wäschestücken aufgenommen wird.Overall, it is expedient to provide a duration of approximately 6 to 30 minutes for each time period, the duration being determined on the basis of the respectively provided parameter in the combined parameter set. These treatment times, in which the laundry moves in the washing liquid and the washing liquid is heated by the parameters, on the one hand long enough to solve the stubborn dirt and to remove from the laundry and on the other hand not too long that the entire washing phase is too long and possibly recontaminations may occur when the dissolved dirt is absorbed in other laundry items located in the washing liquid.

In einer weiteren vorteilhaften Ausführung ist für 10 oder mehr unterschiedliche Fleckenarten oder Verschmutzungsarten jeweils ein spezifischer Parametersatz vorhanden. Damit können die im Haushalt am häufigsten vorkommenden Fleckenarten zu deren Beseitigung auf einfache Weise an der Waschmaschine ausgewählt werden. Dies sind unter anderem Flecken die aus Babynahrung, Blut, Ei, Erde/Sand, Gras, Kaffee, Kosmetik, Obst, Rotwein, Schokolade, Schweiß, Sonnenschutz, Speisefett, Tee oder Tomaten entstanden sind.In a further advantageous embodiment, a specific parameter set is available for each of 10 or more different types of stains or types of soiling. Thus, the most commonly occurring in the household types of stains to their disposal to simple Be selected at the washing machine. These include stains from baby food, blood, egg, earth / sand, grass, coffee, cosmetics, fruit, red wine, chocolate, sweat, sunscreen, edible fat, tea or tomatoes.

In einer weiteren, vorteilhaften Ausführung wird anhand der Rangkennung eine Unverträglichkeit eines Parameters aus einem ersten ausgewählten Parametersatz mit einem Parameter aus einem zweiten ausgewählten Parametersatz festgestellt. Bei einer festgestellten Unverträglichkeit, also wenn eine Zusammenstellung des kombinierten Parametersatzes nicht möglich ist, wird der Parameter aus dem zuerst ausgewählten Parametersatz in den kombinierten Parametersatz übernommen und die Unverträglichkeit dem Benutzer gemeldet, so dass dieser die Wäschestücke mit der zuletzt genannten Verschmutzungsart aus dem Wäscheposten entfernen kann. Dadurch wird sichergestellt, dass eine Fixierung einer Verschmutzung durch eine falsche Behandlung vermieden wird.In a further advantageous embodiment, an incompatibility of a parameter from a first selected parameter set with a parameter from a second selected parameter set is determined on the basis of the rank identifier. If an incompatibility is detected, ie if a combination of the combined parameter set is not possible, the parameter is taken from the first selected parameter set into the combined parameter set and the incompatibility is reported to the user, so that he removes the laundry items from the laundry item with the last-mentioned type of contamination can. This ensures that a fixation of a contamination by a wrong treatment is avoided.

Der Parameter TSoll gibt die Temperatur der Waschflüssigkeit für den nachfolgenden Zeitabschnitt Waschen WS an, wobei hierbei die vom Benutzer gewählte Temperatur eingestellt wird. Der Parameter "Waschen Zeitfaktor" legt die Dauer des Zeitabschnitts für Waschen WS fest. Der Parameter "T Verlauf" legt das Heizverhalten in zeitlicher Erstreckung fest, in diesem Beispiel soll kein Nachheizen nach Erreichen der vom Benutzer vorgegebenen Temperatur erfolgen. Für jeden Parameter in den jeweiligen spezifischen Parametersätzen ist eine Rangkennung zugeordnet, anhand derer die Auswahl der einzelnen Parameter aus mehreren Parametersätzen für den Eintrag in den kombinierten Parametersatz erfolgt.In Fig. 3 is exemplified by a tabular representation of the selection process for the compilation of the combined parameter set clarified. In this case, a specific parameter set Stain 1, Stain 2, Stain 3 is provided for each type of pollutant or stain type to be selected. In the parameter set for spot 3, which is suitable for the removal of blood, a parameter "prewash time factor" for determining the duration of the time interval for the pre-wash VW is determined, a parameter "prewash heat" determines the activation of the radiator 7 during the Prewash, the parameter "Preserve time factor" determines the duration of the time interval for a pretreatment, which may differ from the pre-wash with regard to duration, drum movement or water level. For the spot 3, the time factor = 0 is given for the pretreatment, so that there is no pretreatment for this spot per se. The parameter TSoll indicates the temperature of the washing liquid for the subsequent washing WS period, in which case the temperature selected by the user is set. The parameter "Washing time factor" determines the duration of the period for washing WS. The parameter "T gradient" determines the heating behavior in temporal extension, in this example, no reheating should take place after reaching the temperature specified by the user. For each parameter in the respective specific parameter sets, a rank identifier is assigned, on the basis of which the selection of the individual parameters from several parameter sets for the entry in the combined parameter set takes place.

Im Folgenden wird nun die Auswahl der einzelnen Parameter für den kombinierten Parametersatz erläutert. Der Benutzer hat in diesem Beispiel als erste Fleckenart "Fett" als zweite Fleckenart "Kaffee" und als dritte Fleckenart "Blut" ausgewählt, die aus der Wäsche 8 zu entfernt werden sollen. Der Parameter "Vorbeh. Zeitfaktor=2" im spezifischen Parametersatz für "Fett" hat die Rangkennung 2, der Parameter "Vorbeh. Zeitfaktor" in den anderen spezifischen Parametersätzen hat die Rangkennung 0, so dass hierbei der Parameter "Vorbeh. Zeitfaktor =2" mit der Rangkennung 2 aus dem spezifischen Parametersatz für die Fleckenart "Fett" in den kombinierten Parametersatz übernommen wird, weil er den höchsten Rang hat. Für den nächsten Parameter "T Soll" hat der Parameter im spezifischen Parametersatz für den Fleck 2, der für "Kaffee" vorgesehen ist, den höchsten Rang. Deshalb wird der Parameter "TSoll = TAnwahl +5K" in den kombinierten Parametersatz übernommen. Mit diesem Parameter wird bestimmt, dass die vom Benutzer ausgewählte Temperatur für die Waschflüssigkeit beim Waschen WS um 5 K erhöht wird. Im spezifischen Parametersatz zum Fleck 3, der für "Blut" bestimmt ist, sind zusätzlich Parameter zum Konfigurieren der Vorwäsche vorhanden, wobei in diesem Beispiel der Parameter "Vorwäsche Zeitfaktor" die Dauer und der Parameter "Vorwäsche Heizen" die Aktivität des Heizkörpers und daraus folgend das Temperaturverhalten der Waschflüssigkeit im Zeitabschnitt Vorwäsche bestimmt. Da in den beiden anderen spezifischen Parametersätzen keine Vorwäsche vorgesehen ist, werden diese beiden Parameter aus dem spezifischen Parametersatz für den Fleck 3 (Blut) in den kombinierten Parametersatz übernommen. Der Parameter "Waschen Zeitfaktor = 2" hat im spezifischen Parametersatz für "Blut" die höchste Rangkennung, so dass dieser Parameter in den kombinierten Parametersatz übernommen wird.The following section explains how to select the individual parameters for the combined parameter set. In this example, the user has selected "fat" as the second stain type "coffee" as the first stain type, and "blood" as the third stain type to be removed from the laundry 8. The parameter "Preselected time factor = 2" in the specific parameter set for "Grease" has the rank identifier 2, the parameter "Presumed time factor" in the other specific parameter sets has the rank identifier 0, so that in this case the parameter "Reserved time factor = 2" is taken from the specific parameter set for the "fat" type of speckle in the combined parameter set because it has the highest rank. For the next parameter "T target", the parameter in the specific parameter set for the spot 2 intended for "coffee" has the highest rank. For this reason, the parameter "TSol = TAnwahl + 5K" is adopted in the combined parameter set. This parameter determines that the washing temperature selected by the user when washing WS is increased by 5K. In the specific parameter set for Stain 3, which is intended for "blood", additional parameters for configuring the pre-wash are present, in this example, the parameter "prewash time factor" the duration and the parameter "prewash heating" the activity of the radiator and consequent the temperature behavior of the washing liquid determined during the pre-wash period. Since no prewash is provided in the other two specific parameter sets, these two parameters are taken from the specific parameter set for stain 3 (blood) into the combined parameter set. The parameter "Washing time factor = 2" has the highest rank identifier in the specific parameter set for "blood" so that this parameter is adopted in the combined parameter set.

Wenn der Benutzer die Fleckenauswahl beendet hat und die Zusammenstellung des kombinierten Parametersatzes komplett ist, wird das Waschprogramm WP aktiviert, wobei die Durchführung der Waschphase durch die Parameter aus dem kombinierten Parametersatz festgelegt ist.When the user has finished the spot selection and the combination of the combined parameter set is complete, the washing program WP is activated, whereby the execution of the washing phase is determined by the parameters from the combined parameter set.
