Description

Die Erfindung betrifft eine Waschmaschine. Insbesondere betrifft die Erfindung eine Waschmaschine, welche mindestens einen Speicher aufweist, in dem mindestens ein Sonderprogramm, mindestens ein Waschprogramm und mindestens eine dem Sonderprogramm und/oder dem Waschprogramm zuordnbare Programmoption hinterlegt sind.The invention relates to a washing machine. In particular, the invention relates to a washing machine which has at least one memory in which at least one special program, at least one washing program and at least one program option that can be assigned to the special program and / or the washing program are stored.

Das Sonderprogramm ist ausgelegt, wäschefrei durchgeführt zu werden, während das Waschprogramm zum Waschen von Wäsche ausgelegt ist. D.h., bei der Durchführung des Sonderprogramms soll eine Trommel der Waschmaschine nicht mit Wäsche beladen sein, während bei der Durchführung des Waschprogramms die Trommel mit Wäsche beladen sein soll. Während das Sonderprogramm und das Waschprogramm nur alternativ anwählbar sind, ist die mindestens eine Programmoption zusammen mit dem Sonderprogramm und/oder dem Waschprogramm anwählbar. Daher ist die mindestens eine Programmoption dem Sonder- und/oder Waschprogramm zuordnbar. Jede Programmoption ist ausgelegt, bei ihrer Anwahl mit dem Sonder- oder Waschprogramm mindestens einen Prozessparameter des angewählten Sonder- oder Waschprogramms zu ändern.The special program is designed to be carried out without laundry, while the washing program is designed to wash laundry. This means that a drum of the washing machine should not be loaded with laundry when executing the special program, while the drum should be loaded with laundry when executing the washing program. While the special program and the washing program can only be selected alternatively, the at least one program option can be selected together with the special program and / or the washing program. The at least one program option can therefore be assigned to the special and / or washing program. Each program option is designed to change at least one process parameter of the selected special or wash program when selected with the special or wash program.

Ferner weist die Waschmaschine eine Bedieneinrichtung auf, über die das mindestens eine Sonderprogramm, das mindestens eine Waschprogramm und die mindestens eine Programmoption anwählbar sind, und eine Regel- und/oder Steuereinrichtung auf, welche ausgebildet ist, eine Durchführung des mindestens einen Sonderprogramms und/oder Waschprogramms nach seiner Anwahl zu regeln und/oder zu steuern.Furthermore, the washing machine has an operating device via which the at least one special program, the at least one washing program and the at least one program option can be selected, and a regulating and / or control device which is designed to carry out the at least one special program and / or Regulate and / or control the washing program according to its selection.

Das Sonderprogramm wie beispielsweise ein Kalibrierprogramm muss ohne Beladung einer Trommel der Waschmaschine mit Wäsche durchgeführt werden. Solch ein Sonderprogramm kann eine Unterstützung einer oder mehrerer Programmoptionen zum Verändern eines oder mehrerer Prozessparameter des Sonderprogramms bieten. Die Ausführung von einer oder mehreren angewählten Programmoptionen während des Sonderprogramms führt jedoch zu einem nicht optimalen Programmablauf des Sonderprogramms und kann zu einer fehlerhaften Kalibrierung und insbesondere zu einer fehlerhaften Beladungsmessung führen. Nachfolgend ablaufende Waschprogramme weisen dann aufgrund der fehlerhaften Beladungsmessung ebenfalls einen nicht optimalen Programmablauf auf.The special program, such as a calibration program, must be carried out without loading a drum of the washing machine with laundry. Such a special program can offer support for one or more program options for changing one or more process parameters of the special program. However, the execution of one or more selected program options during the special program leads to a non-optimal program sequence of the special program and can lead to an incorrect calibration and in particular to an incorrect load measurement. Subsequent washing programs then also have a non-optimal program sequence due to the incorrect load measurement.

Die DE 198 50 860 A1 , DE 10 2010 016672 B3 und CN 102 234 901 A beschreiben Waschmaschinen mit einer Programmsteuerung.The DE 198 50 860 A1 , DE 10 2010 016672 B3 and CN 102 234 901 A describe washing machines with a program control.

Der Erfindung stellt sich somit das Problem, eine Waschmaschine und ein Verfahren zum Betreiben einer Waschmaschine bereitzustellen, die einen optimierten Programmablauf ermöglichen.The invention thus poses the problem of providing a washing machine and a method for operating a washing machine which enable an optimized program sequence.

Erfindungsgemäß wird dieses Problem durch eine Waschmaschine mit den Merkmalen des Patentanspruchs 1 und ein Verfahren mit den Merkmalen des Patentanspruchs 7 gelöst.According to the invention, this problem is solved by a washing machine with the features of patent claim 1 and a method with the features of patent claim 7.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.Advantageous refinements and developments of the invention emerge from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen neben einen optimierten Programmablauf darin, dass ein Nutzer der Waschmaschine nicht irritiert ist, dass er keine Programmoption(en) bei Anwahl des Sonderprogramms anwählen kann. Schlimmstenfalls kann der Nutzer, wenn er keine Programmoption anwählen kann, denken, dass die Waschmaschine nicht funktionstüchtig sei. Daher ist es vorteilhaft, ihm die Anwahl der Programmoption(en) zu ermöglichen. Die Bedienung wird hierdurch erleichtert. Erfindungsgemäß ist vorgesehen, dass die Regel- und/oder Steuereinrichtung ausgelegt ist, das Sonderprogramm nach Anwahl des Sonderprogramms und der mindestens einen Programmoption derart zu steuern und/oder zu regeln, dass die Programmoption unberücksichtigt bleibt oder zu einem geringeren Maß berücksichtigt wird als bei einer Regelung und/oder Steuerung des Waschprogramms nach Anwahl des Waschprogramms und der mindestens einen Programmoption.The advantages that can be achieved with the invention, in addition to an optimized program sequence, consist in the fact that a user of the washing machine is not confused that he cannot select any program option (s) when selecting the special program. In the worst case, if the user cannot select a program option, he may think that the washing machine is not functional. It is therefore advantageous to enable him to select the program option (s). This makes operation easier. According to the invention it is provided that the regulating and / or control device is designed to control and / or regulate the special program after the special program and the at least one program option have been selected in such a way that the program option is not taken into account or is taken into account to a lesser extent than with one Regulation and / or control of the washing program after selecting the washing program and the at least one program option.

Dadurch kann ein ordnungsgemäßer Ablauf des Sonderprogramms sichergestellt werden, während dem Nutzer ein einheitliches Erscheinungsbild geboten wird.This can ensure that the special program runs properly, while the user is offered a uniform appearance.

Erfindungsgemäß ist die Regel- und/oder Steuereinrichtung ausgelegt, das Sonderprogramm, wenn die Programmoption unberücksichtigt bleibt, derart zu steuern und/oder regeln, wie es in dem Speicher der Waschmaschine hinterlegt ist. D.h., die Regel- und Steuereinrichtung ist ausgelegt, die angewählte(n) Programmoption(en) zu ignorieren und das Sonderprogramm derart zu regeln und/oder zu steuern, als wäre(n) die Programmoption(en) nicht angewählt. Die Regel- und/oder Steuereinrichtung ist daher ausgelegt, das Sonderprogramm in diesem Fall prozessparameteränderungsfrei durchzuführen. Wenn z.B. die angewählte Programmoption eine Wasser plus Funktion ist, mit der als Prozessparameter ein Wasserstand in einem Laugenbehälter der Waschmaschine im Vergleich zur ausschließlichen Anwahl des Sonder- oder Waschprogramms angehoben wird, ist die Regel- und/oder Steuereinrichtung ausgelegt, die Wasserstandsanhebung bei Anwahl des Sonderprogramms und der Wasser plus Funktion nicht auszuführen.According to the invention, the regulating and / or control device is designed to control and / or regulate the special program in such a way as it is stored in the memory of the washing machine, if the program option is not taken into account. That is, the regulating and control device is designed to ignore the selected program option (s) and to regulate and / or control the special program as if the program option (s) were not selected. The regulating and / or control device is therefore designed to carry out the special program without any process parameter changes in this case. If, for example, the selected program option is a water plus function with which, as a process parameter, the water level in a tub of the washing machine is raised compared to the exclusive selection of the special or washing program, the regulating and / or control device is designed to increase the water level when the Special program and the water plus function cannot be executed.

Erfindungsgemäß ist die Regel- und/oder Steuereinrichtung ausgelegt, das Sonderprogramm, wenn die mindestens eine angewählte Programmoption bei der Regelung und/oder Steuerung des Sonderprogramms zu einem geringeren Maß berücksichtigt wird als bei einer Regelung und/oder Steuerung des Waschprogramms nach Anwahl des Waschprogramms und der mindestens einen Programmoption, derart zu steuern und/oder zu regeln, dass der mindestens eine Prozessparameter des Sonderprogramms, der von einer Änderung durch die mindestens eine angewählte Programmoption betroffen ist, einen Bruchteil eines Werts beträgt, der dem mindestens einen Prozessparametern des Waschprogramms zugeordnet ist, wenn das mindestens eine Waschprogramm und die mindestens eine Programmoption angewählt sind. Wenn z.B. die angewählte Programmoption die vorstehend erwähnte Wasser plus Funktion ist, mit der der Wasserstand in dem Laugenbehälter als Prozessparameter im Vergleich zur ausschließlichen Anwahl des Sonder- oder Waschprogramms angehoben wird, ist die Regel- und/oder Steuereinrichtung ausgelegt, die Wasserstandsanhebung bei Anwahl des Sonderprogramms und der Wasser plus Funktion nur mit einem geringeren Wasser-Offset-Wert im Vergleich zur Anwahl des Waschprogramms und der Wasser plus Funktion auszuführen.According to the invention, the regulating and / or control device is designed, the special program if the at least one selected program option is taken into account to a lesser extent in the regulation and / or control of the special program than in a regulation and / or control of the washing program after the washing program has been selected and to control and / or regulate the at least one program option in such a way that the at least one process parameter of the special program that is affected by a change by the at least one selected program option is a fraction of a value that is assigned to the at least one process parameter of the washing program if the at least one wash program and the at least one program option have been selected. If e.g. the selected program option is the aforementioned water plus function, with which the water level in the suds container is raised as a process parameter compared to the exclusive selection of the special or washing program, the regulation and / or control device is designed, the water level increase when the special program is selected and the water plus function can only be executed with a lower water offset value compared to the selection of the washing program and the water plus function.

Die Regel- und/oder Steuereinrichtung ist bevorzugt ausgelegt, bei Anwahl mehrerer Programmoptionen mit dem Sonderprogramm, jede einzelne Programmoption entweder unberücksichtigt zu lassen oder zu einem geringeren Maß zu berücksichtigen als bei der Regelung und/oder Steuerung des Waschprogramms nach Anwahl des Waschprogramms und der jeweiligen Programmoption.The regulating and / or control device is preferably designed so that when several program options are selected with the special program, each individual program option is either ignored or taken into account to a lesser extent than when regulating and / or controlling the washing program after selecting the washing program and the respective one Program option.

In einer bevorzugten Ausführungsform ist das Sonderprogramm ein Kalibrierprogramm und/oder ein Erstinbetriebnahmeprogramm. Das Kalibrierprogramm ist ausgebildet, die Waschmaschine nach einer Reparatur zu kalibrieren. Das Erstinbetriebnahmeprogramm ist ausgelegt, die Waschmaschine bei ihrer ersten Inbetriebnahme zu kalibrieren. Durch die erfindungsgemäße Ausbildung der Regel- und/oder Steuereinrichtung wird ein korrektes Kalibrierergebnis sichergestellt. Eine genauere Kalibrierung wird dadurch gewährleistet. Das Sonderprogramm kann aber auch ein Waschmaschinenreinigungsprogramm sein, welches ausgelegt ist, die Waschmaschine zu reinigen.In a preferred embodiment, the special program is a calibration program and / or an initial start-up program. The calibration program is designed to calibrate the washing machine after a repair. The initial start-up program is designed to calibrate the washing machine when it is used for the first time. The inventive design of the regulating and / or control device ensures a correct calibration result. This ensures a more precise calibration. The special program can also be a washing machine cleaning program which is designed to clean the washing machine.

Das Waschprogramm weist bevorzugt folgende Programmphasen auf: Zuerst wird eine Erfassungsphase, dann eine Waschphase, dann eine Spülphase und dann eine Schleuderphase durchgeführt. In diesen einzelnen Phasen wird ein Wasserzulauf und -ablauf der Waschmaschine entsprechend geregelt und/oder gesteuert. Zu Beginn des Waschprogramms wird in der Erfassungsphase die sich in der Trommel befindende Wäsche erfasst, um die Beladungsmenge zu ermitteln. Hierbei wird Wasser in den Laugenbehälter der Waschmaschine eingelassen. Anschließend folgt in der Waschphase ein Aufheizabschnitt, in dem das Wasser mittels einer Heizeinrichtung auf eine vorbestimmte Waschtemperatur erhitzt wird, die von dem angewählten Waschprogramm vorgegeben ist. Nach Erreichen der vorgegeben Waschtemperatur wird die Heizeinrichtung abgeschaltet und ein Nachwaschabschnitt folgt. In diesem Nachwaschabschnitt wird die Trommel rotierend bewegt, wobei sich das Wasser abkühlt. Die Waschphase wird mit einem Abpumpen des Wassers aus dem Laugenbehälter beendet. Beim Abpumpen kann optional geschleudert werden. Anschließend folgt die Spülphase mit einem oder mehreren Spülabschnitten, bei denen jeweils frisches Wasser in den Laugenbehälter eingelassen und die Trommel rotiert wird. Zum Ende jedes Spülabschnitts wird das Spülwasser abgepumpt. Anschließend folgt die Schleuderphase. Bei der Schleuderphase wird die Trommel mit einer gegenüber der Waschphase erhöhte Drehzahl gedreht, wobei das Wasser aus dem Laugenbehälter durch Abpumpen entfernt wird.The washing program preferably has the following program phases: First a detection phase, then a washing phase, then a rinsing phase and then a spin phase are carried out. In these individual phases, a water inlet and outlet of the washing machine is regulated and / or controlled accordingly. At the beginning of the washing program, the laundry in the drum is detected in the detection phase in order to determine the load quantity. Here, water is let into the tub of the washing machine. This is followed by a washing phase Heating section in which the water is heated to a predetermined washing temperature by means of a heating device, which is specified by the selected washing program. After reaching the predetermined washing temperature, the heating device is switched off and a post-washing section follows. In this post-washing section, the drum is rotated, and the water cools down. The washing phase ends by pumping the water out of the tub. When pumping, it can optionally be spun. This is followed by the rinsing phase with one or more rinsing sections, in which fresh water is let into the tub and the drum is rotated. At the end of each flushing section, the flushing water is pumped out. This is followed by the spin phase. During the spinning phase, the drum is rotated at a higher speed than in the washing phase, the water being removed from the tub by pumping out.
