Abstract

A method for drying clothes in a device comprising a rotatable drum for agitating the clothes. Following a drying program, an anti-crease cycle is provided during which the clothes are intermittently agitated. Said anti-crease cycle protects the clothes from permanent creases by regularly agitating them. In order to save energy and to save the clothes and the device, the clothes are only agitated to such a degree during the anti-crease cycle that crease-formation is avoided.

Description

Beschreibung Verfahren und Vorrichtung zum Trocken von Wäsche Description Method and device for drying laundry
[001] Die vorliegende Erfindung betrifft ein Verfahren und eine Vomchtung zum Trocknen von Wäsdie.The present invention relates to a method and a device for drying washes.
[002] Beim Trocknen von Wäsche mit einem Wäschetrockner, der eine drehbare Trommel zur Aufnahme der Wäsche hat, wird am Ende eines Trocknungsprogramms bzw. einer Trocknungsphase eine Knitterschutzphase angefügt. Ein Trocknungsprogramm hat üblidierweise anfänglich eine sogenannte Aufheizphase, eine sich daran anschließende eigentliche Trocknungsphase und eine sich daran anschließende Abkühlphase. Während all dieser zu einem Trocknungsprogramm gehörenden Phasen wird die Trommel üblicherweise ständig gedreht. Dies gilt auch während der Abkühlphase, bei der lediglich die Heizung abgeschaltet ist. Wird am Ende eines Trocknungsprogramms die getrocknete Wäsche nicht sofort a s der Trommel genommen, so können sich Knitter in die Wäsche fixieren. Um dies zu verhindern, wird während einer sich anschließenden Knitterschitzphase entweder kontinuierlich die Trommel weitergedreht oder die Trommel intermittierend gedreht.When drying laundry with a tumble dryer that has a rotatable drum for receiving the laundry, a crease protection phase is added at the end of a drying program or a drying phase. A drying program usually has a so-called heating phase, a subsequent actual drying phase and a subsequent cooling phase. During all of these phases of a drying program, the drum is usually rotated continuously. This also applies during the cooling phase, when only the heating is switched off. If the dried laundry is not immediately removed from the drum at the end of a drying program, creases can become entangled in the laundry. To prevent this, the drum is either continuously rotated during a subsequent crease phase or the drum is rotated intermittently.
[003] Durch das ständige Drehen der Trommel oder durch das intermittierende Drehen der Trommel während der Knitterschitzphase wird die in der Trommel befindliche Wäsche immer wieder aufgelockert, so dass sich keine Knitter in der Wäsche fixieren können. Das intermittierende Drehen der Trommel erfolgt üblicherweise nach einem festen Muster, wie bspw. zwei Minuten Trommelstillstand und daran anschließen fünfzehn Sekunden Trommeldrehen. Dieses Intermittieren dauert entweder bis zum Ende der Knitterschutzphase, die bis zu drei oder fünf Stunden dauern kann oder bis zu dem Zeitpunkt, an dem die Wäsche aus der Trommel entnommen wird. Nachteilig an dieser Knitterschutzphase ist die Tatsache, dass die Wäsche durch die Trommelbewegung einer weiteren Belastung aisgesetzt wird. Durch das ständige Ein- und Ausschalten wird weiterhin der Antriebsmotor und die Schaltelemente zum Ein- und Ausschalten des Antriebsmotors belastet.By constantly rotating the drum or by intermittently rotating the drum during the crease phase, the laundry in the drum is loosened again and again, so that no creases can be fixed in the laundry. The intermittent rotation of the drum is usually carried out according to a fixed pattern, such as, for example, two minutes of drum stoppage and then fifteen seconds of drum rotation. This intermittent lasts either until the end of the anti-crease phase, which can take up to three or five hours, or until the laundry is removed from the drum. A disadvantage of this anti-crease phase is the fact that the laundry is subjected to a further load due to the drum movement. Due to the constant switching on and off, the drive motor and the switching elements for switching the drive motor on and off are still loaded.
[004] Die Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Vorrichtung zum Trocknen von Wäsche zur Verfügung zu stellen, die eine Knitterschutzphase hat, bei der die Wäsche und auch die Bauteile der Vorrichtung geschont wird, und bei der die Knitterbildung optimal vermieden wird und der Energieverbrauch gesenkt wird.The object of the present invention is to provide a method and a device for drying laundry, which has an anti-crease phase, in which the laundry and also the components of the device are protected, and in which the formation of creases is optimally avoided and energy consumption is reduced.
[005] Diese Aufgabe wird bzgl. des Verfahrens jeweils durch die Merkmale des Patentanspruchs 1, 2, 3 oder 4 gelöst. Diese Aufgabe wird bzgl. der Vorrichtung durch die Merkmale des Patentanspruchs 14 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved with respect to the method by the features of claim 1, 2, 3 or 4. This task is performed by the device Features of claim 14 solved. Advantageous refinements and developments of the invention result from the subclaims.
[006] Bei einem Verfahren zum Trocknen von Wäsche in einer Vorrichtung mit einer drehbaren Trommel zum Bewegen der Wäsdie schließt sich an ein Trocknungsprogramm eine Knitterschitzphase, bei der die Wäsche zeitweise bewegt und zeitweise nicht bewegt wird.In a method for drying laundry in a device with a rotatable drum for moving the laundry, a drying program is followed by a crease phase in which the laundry is moved at times and is not moved at times.
[007] Indem im Verlauf der Knitterschitzphase die Bewegung der Wäsche mit fortschreitender Zeit abnimmt, oder indem die Bewegung der Wäsche während der Knitterschitzphase mit Abnehmen der Temperatur der Wäsche und/oder mit Abnehmen der Restfeuchte der Wäsche abnimmt, oder indem die Bewegung der Wäsche während der Knitterschitzphase abhängig vom vorgewählten Trocknungsprogramm und/oder vom vorgewählten Trocknungsgrad und/oder der vorgewählten Wäscheart erfolgt, oder indem die Bewegung der Wäsche während der Knittersdiitzphase abhängig von der durch einen Benutzer voreingestellten Wäschemenge und/oder der durch die Vorrichtung ermittelten Wäschemenge erfolgt, wird erreicht, dass die Wäsche während der Knitterschitzphase nur soviel bewegt, um eine Knitterbildung zu vermeiden. Dadurch wird die Wäsdie während der Knittersdiitzphase nur minimal bewegt bzw. aufgelockert und somit sehr schonend behandelt, wobei Knitterbildung optimal vermieden werden kann. Weiterhin wird der Motor zum Drehen der Trommel weniger häufig ein- und ausgeschaltet, insbesondere gegen Ende der Knittersdiitzphase wird die Einschaltzeit der Trommelbewegung stark verringert, so dass die Bauteile zur Trommelbewegung, wie Motor, Relais zum Ein- und Ausschalten des Motors und Trommellagerung weniger beansprucht werden und damit die Lebensdauer und die Zuverlässigkeit der Vorrichtung erhöht wird. Weiterhin wird Energie gespart, da sich die Einschaltdauer der Trommelbewegung während und im Verlauf der Knittersdiitzphase insgesamt stark verkürzt.By decreasing the movement of the laundry over time in the course of the crease phase, or by the movement of the laundry during the crease phase with a decrease in the temperature of the laundry and / or with a decrease in the residual moisture of the laundry, or by the movement of the laundry during the crease phase depends on the preselected drying program and / or on the preselected degree of dryness and / or on the preselected type of laundry, or by moving the laundry during the crease phase depending on the amount of laundry preset by a user and / or the amount of laundry determined by the device that the laundry only moves so much during the crease phase to avoid creasing. As a result, the water is only minimally agitated or loosened during the wrinkling phase and is therefore treated very gently, and wrinkling can be optimally avoided. Furthermore, the motor for rotating the drum is switched on and off less frequently, in particular towards the end of the knitting phase, the switch-on time of the drum movement is greatly reduced, so that the components for drum movement, such as the motor, relays for switching the motor on and off, and drum mounting are less stressed be and thus the life and reliability of the device is increased. Furthermore, energy is saved because the on-time of the drum movement is greatly reduced overall during and during the knitting phase.
[008] Da zu Beginn der Knittersdiitzphase die Wäschetemperatur und auch die Restfeuchte noch erhöht ist, ist zu Beginn der Knitterschitzphase die Gefahr der Fixierung von Knittern in der Wäsche höher als gegen Ende der Knitterschitzphase, so dass zu Beginn der Knittersdiitzphase zur optimalen Vermeidung von Knitterbildung in der Wäsche ein höherer Bewegungsanteil der Wäsche erforderlich ist als gegen Ende der Knitterschitzphase. Weiterhin kann der Bewegungsanteil optimal an das vorgewählte Trocknungsprogramm oder an den vorgewählten Trocknungsgrad oder die vorgewählte Wäscheart angepasst werden. Beispielsweise benötigt ein Trocknun s ro ramm "Bü elfeucht" ins esamt einen etwa höheren Bewe un santeil als ein Trocknungsprogramm "Schranktrocken" oder "Sehr Trocken". Weiterhin kann der Bewegungsanteil optimal an die in der Trommel befindliche Wäschemenge angepasst werden. Für jeden Betriebszustand kann daher der Bewegungsanteil der Wäsche derart minimiert werden, so dass die Wäsche und die Bauteile der Vorrichtung geschont werden und der Energieverbrauch reduziert wird.Since the laundry temperature and the residual moisture is still increased at the beginning of the crease phase, the risk of wrinkles being fixed in the laundry at the start of the crease phase is higher than towards the end of the crease phase, so that at the start of the crease phase to optimally avoid crease formation in the laundry a higher proportion of movement of the laundry is required than towards the end of the crease phase. Furthermore, the movement component can be optimally adapted to the preselected drying program or to the preselected degree of dryness or the selected type of laundry. For example, a "Büelfeucht" drying ram needs a slightly higher weight percentage than one Drying program "Cupboard dry" or "Very dry". Furthermore, the amount of movement can be optimally adapted to the amount of laundry in the drum. For each operating state, the amount of movement of the laundry can therefore be minimized so that the laundry and the components of the device are protected and the energy consumption is reduced.
[009] In einer vorteilhaften Ausführung werden daher zum Erreichen dieser Ziele die Bewegung der Wäsche während der Knitterschitzphase in Abhängigkeit von Messg rößen und Parametern durchgeführt, die in vorausgehenden Phasen eines Trocknungsprogramms und/oder während der Knittersdiitzphase erfasst werden.In an advantageous embodiment, therefore, to achieve these goals, the movement of the laundry during the crease phase is carried out as a function of measured variables and parameters, which are recorded in previous phases of a drying program and / or during the crease phase.
[010] Hierbei können auch Messgrößen und Parameter berücksichtigt werden, die während einer Aufheizphase zu Beginn eines Trocknungsprogramms und/oder während einer Abkühlphase zum Schluss eines Trocknungsprogramms erfasst werden.Measured variables and parameters can also be taken into account here, which are recorded during a heating phase at the beginning of a drying program and / or during a cooling phase at the end of a drying program.
[011] In einer vorteilhaften Ausführung können daher zum Erreichen der vorstehenden Ziele als Messgrößen und als Parameter insbesondere die Wäschemasse und/oder die Aufheizdauer und/oder die Wäschefeuchtigkeit und/oder der Wäschefeuchtigkeitsverlauf und/oder Wäscheleitwert und/oder der Verlauf des Wäscheleitwerts und/ oder der Feuchtigkeitsgehalt und/oder der Feuchtigkeitsverlauf und/oder die Temperatur der Wäsdie und/oder der Temperaturverlauf der Wäsdie und/oder der Temperatur der Trocknungsluft und/oder der Temperaturverlauf der Trocknungsluft in der Trommel des Trockners und/oder der Vergleich von Feuchtigkeitsgehalt und/oder Feuchtigkeitsverlauf und/oder der Temperatur der Trocknungsluft und/oder der Temperaturverlauf der Trocknungsluft in der Trommel des Trockners zwischen Eintritt in die Trommel und Austritt aus der Trommel und/oder die Zeitdauer bis zum Erreichen eines Trockenziels verwendet werden.In an advantageous embodiment, therefore, in order to achieve the above goals as measurement variables and as parameters, in particular the laundry mass and / or the heating-up time and / or the laundry moisture content and / or the laundry moisture profile and / or the laundry conductivity value and / or the laundry conductivity value profile and / or the moisture content and / or the moisture profile and / or the temperature of the washer and / or the temperature profile of the washer and / or the temperature of the drying air and / or the temperature profile of the drying air in the drum of the dryer and / or the comparison of moisture content and / or the moisture profile and / or the temperature of the drying air and / or the temperature profile of the drying air in the drum of the dryer between entry into the drum and exit from the drum and / or the period of time until a drying target is reached.
[012] Hierzu hat die drehbar Trommel während der Knitterschitzphase Drehbewegungszeitabschnitte und Stillstandszeitabschnitte. Während der Drehbewegungszeitabschnitte der Trommel kann die Trommel in eine Drehrichtung gedreht werden und/ oder reversierend in unterschiedliche Drehrichtungen gedreht werden. Die Dauer einer Knitterschutzphase beträgt bevorzugt ein bis fünf Stunden.For this purpose, the rotatable drum has rotational movement periods and standstill periods during the crease phase. During the rotational movement periods of the drum, the drum can be rotated in one direction of rotation and / or reversely rotated in different directions of rotation. The duration of an anti-crease phase is preferably one to five hours.
[013] In einer bevorzugten Ausführung ist die Dauer der Knitterschitzphase in vier Zeitabschnitte unterteilt, wobei in einem ersten Zeitabschnitt die Bewegungsanteile zwischen 20% und 90% und in einem zweiten Zeitabschnitt die Bewegungsanteile zwischen 10% und 70% liegen und in einem dritten Bewegungsabschnitt die Bewegungsanteile zwisdien 1% und 60% liegen und in einem vierten Zeitabschnitt die Bewegungsanteile zwischen 1% und 30% liegen.

[018] Darin zeigen:Therein show:
[019] Figur 1 eine Vorrichtung zum Trocknen von Wäsche.Figure 1 shows a device for drying laundry.
[020] Gemäß Figur 1 hat eine Vorrichtung zum Trocknen von Wäsche ein Gehäuse 1, in der eine Trommel 2 drehbar gelagert ist, eine Beschickungstür 3, ein vorderes Lagerschild 4, einen Zufuhrkanal 5 für Trocknungsluft, in der eine Heizeinrichtung 6 angeordnet ist, einen Auslasskanal 7 für Trocknungsluft, in dem ein Gebläse 8 angeordnet ist und einen Motor 9, der über einen Riemen 10 die Trommel 2 antreibt. Weiterhin ist eine Steuerungseinrichlung 11 vorgesehen, die eine Eingabeeinrichtung 12 und eine Zeitglied 13 umfasst. Ein erster Temperaturfühler 14 ist im Zuluftkanal 5 benachbart zum Eintritt in die Trommel 2 angeordnet, ein zweiter Temperaturfühler 15 ist im Auslasskanal 7 benachbart zur Trommel 2 angeordnet. Am vorderen Lagerschild 4 sind zwei Elektroden 16 zum Erfassen des Leitwerts der Wäsche und oder der Trocknungsluft angeordnet. Der erste Temperaturfühler 14, der zweite Temperaturfühler 15 und die Elektroden sind mit der Steuerungseinrichtung 11 verbunden, die in der Lage ist, die Signale von den Sensoren und der Eingabeeinrichtung 12 zu verarbeiten. Die vorstehend dargestellte Vorrichtung zum Trocknen von Wäsche kann als Ablufttrockner oder als Kondensationstrockner ausgebildet sein.According to Figure 1, a device for drying laundry has a housing 1, in which a drum 2 is rotatably mounted, a loading door 3, a front end plate 4, a supply channel 5 for drying air, in which a heating device 6 is arranged, one Outlet duct 7 for drying air, in which a blower 8 is arranged and a motor 9, which drives the drum 2 via a belt 10. Furthermore, a control device 11 is provided, which comprises an input device 12 and a timer 13. A first temperature sensor 14 is arranged in the supply air duct 5 adjacent to the entry into the drum 2, a second temperature sensor 15 is arranged in the outlet duct 7 adjacent to the drum 2. Two electrodes 16 for detecting the conductivity of the laundry and or the drying air are arranged on the front bearing plate 4. The first temperature sensor 14, the second temperature sensor 15 and the electrodes are connected to the control device 11, which is able to process the signals from the sensors and the input device 12. The device for drying laundry shown above can be designed as an exhaust air dryer or as a condensation dryer.
[021] Die gemäß Figur 1 dargestellte Vorrichtung zum Trocknen von Wäsche kann mit weiteren Sensoren, wie bspw. einem Wäschetemperaturfühler oder dergleichen versehen sein, die erforderlich sind, um die nachstehend dargelegten Verfahrensabläufe und Verfahrensschritte durchzuführen.The device for drying laundry shown in Figure 1 can with further sensors, such as a laundry temperature sensor or the like, which are required to carry out the method sequences and method steps set out below.
[022] Mit der vorstehend dargelegten Vorrichtung zum Trocknen von Wäsche können nachstehend erläuterte Verfahrensabläufe und Verfahrensschritte durchgeführt werden.Processes and process steps explained below can be carried out with the above-described device for drying laundry.
[023] Indem im Verlauf der Knitterschitzphase die Bewegung der Wäsche mit fortschreitender Zeit abnimmt, oder indem die Bewegung der Wäsche während der Knitterschitzphase mit Abnehmen der Temperatur der Wäsche und/oder mit Abnehmen der Restfeuchte der Wäsche abnimmt, oder indem die Bewegung der Wäsche während der Knitterschitzphase abhängig vom vorgewählten Trocknungsprogramm und/oder vom vorgewählten Trocknungsgrad und/oder der vorgewählten Wäscheart erfolgt, oder indem die Bewegung der Wäsche während der Knittersdiitzphase abhängig von der durch einen Benutzer voreingestellten Wäschemenge und/oder der durch die Vorrichtung ermittelten Wäschemenge erfolgt, wird erreicht, dass die Wäsche während der Knitterschitzphase nur soviel bewegt, um eine Knitterbildung zu vermeiden. Dadurch wird die Wäsche während der Knitterschitzphase nur minimal bewegt bzw. aufgelockert und somit sehr schonend behandelt, wobei Knitterbildung optimal vermieden werden kann. Weiterhin wird der Motor zum Drehen der Trommel weniger häufig ein- und ausgeschaltet, insbesondere gegen Ende der Knitterschutzphase wird die Einschaltzeit der Trommelbewegung stark verringert, so dass die Bauteile zur Trommelbewegung, wie Motor, Relais zum Ein- und Ausschalten des Motors und Trommellagerung weniger beansprucht werden und damit die Lebensdauer und die Zuverlässigkeit der Vorrichtung erhöht wird. Weiterhin wird Energie gespart, da sich die Einschaltdauer der Trommelbewegung während und im Verlauf der Knitterschitzphase insgesamt stark verkürzt.By decreasing the movement of the laundry over time in the course of the crease phase, or by the movement of the laundry during the crease phase decreasing as the temperature of the laundry and / or the residual moisture of the laundry decreases, or by the movement of the laundry during the crease phase depends on the preselected drying program and / or on the preselected degree of dryness and / or on the preselected type of laundry, or by moving the laundry during the crease phase depending on the amount of laundry preset by a user and / or the amount of laundry determined by the device that the laundry only moves so much during the crease phase to avoid creasing. As a result, the laundry is only minimally agitated or loosened during the crease phase and is therefore treated very gently, and crease formation can be optimally avoided. Furthermore, the motor for rotating the drum is switched on and off less frequently, in particular towards the end of the anti-crease phase, the switch-on time of the drum movement is greatly reduced, so that the components for drum movement, such as motor, relay for switching the motor on and off and drum mounting are less stressed be and thus the life and reliability of the device is increased. Furthermore, energy is saved because the on-time of the drum movement is greatly reduced overall during and in the course of the crease phase.
[024] Da zu Beginn der Knitterschutzphase die Wäschetemperatur und auch die Restfeuchte noch erhöht ist, ist zu Beginn der Knittersdiitzphase die Gefahr der Fixierung von Knittern in der Wäsche höher als gegen Ende der Knitterschitzphase, so dass zu Beginn der Knitterschitzphase zur optimalen Vermeidung von Knitterbildung in der Wäsche ein höherer Bewegungsanteil der Wäsche erforderlich ist als gegen Ende der Knitterschutzphase. Weiterhin kann der Bewegungsanteil optimal an das vorgewählte Trocknungsprogramm oder an den vorgewählten Trocknungsgrad oder die vorgewählte Wäscheart angepasst werden. Beispielsweise benötigt ein Trocknungsprogramm "Bügelfeucht" insgesamt einen etwa höheren Bewegungsanteil als ein Trocknungsprogramm "Schranktrocken" oder "Sehr Trocken". Weiterhin kann der Be- wegungsanteil optimal an die in der Trommel befindliche Wäschemenge angepasst werden. Für jeden Betriebszustand kann daher der Bewegungsanteil der Wäsche derart minimiert werden, so dass die Wäsche und die Bauteile der Vorrichtung geschont werden und der Energieverbrauch reduziert wird.Since at the beginning of the anti-crease phase the laundry temperature and also the residual moisture is still increased, the risk of wrinkles being fixed in the laundry is higher at the beginning of the anti-crease phase than at the end of the crease phase, so that at the beginning of the crease phase to optimally avoid crease formation in the laundry a higher proportion of the laundry movement is required than towards the end of the anti-crease phase. Furthermore, the movement component can be optimally adapted to the preselected drying program or to the preselected degree of dryness or the selected type of laundry. For example, a drying program called "ironing moisture" requires a somewhat higher proportion of movement than a drying program "cupboard dry" or "very dry". Furthermore, the loading movement proportion can be optimally adapted to the amount of laundry in the drum. For each operating state, the amount of movement of the laundry can therefore be minimized, so that the laundry and the components of the device are protected and the energy consumption is reduced.
[025] Daher kann zum Erreichen dieser Ziele die Bewegung der Wäsche während der Knitterschitzphase in Abhängigkeit von Messgrößen und Parametern durchgeführt werden, die in vorausgehenden Phasen eines Trocknungsprogramms und/oder während der Knitterschitzphase erfasst werden.[025] Therefore, to achieve these goals, the movement of the laundry during the crease phase can be carried out as a function of measurement variables and parameters that are recorded in previous phases of a drying program and / or during the crease phase.
[026] Hierbei können auch Messgrößen und Parameter berücksichtigt werden, die während einer Aufheizphase zu Beginn eines Trocknungsprogramms und/oder während einer Abkühlphase zum Schluss eines Trocknungsprogramms erfasst werden.Measured variables and parameters can also be taken into account here, which are recorded during a heating phase at the beginning of a drying program and / or during a cooling phase at the end of a drying program.
[027] Zum Erreichen der vorstehenden Ziele können als Messgrößen und als Parameter insbesondere die Wäschemasse und/oder die Aufheizdauer und/oder die Wäschefeuchtigkeit und/oder der Wäschefeuchtigkeitsverlauf und/oder Wäscheleitwert und/ oder der Verlauf des Wäscheleitwerts und/oder der Feuchtigkeitsgehalt und/oder der Feuchtigkeitsverlauf und/oder die Temperatur der Wäsche und/oder der Tempera- urverlaif der Wäsche und/oder der Temperatur der Trocknungsluft und/oder der Tem- peraturverlauf der Trocknungsluft in der Trommel des Wäschetrockners und/oder der Vergleich von Feuchtigkeitsgehalt und/oder Feuchtigkeitsverlauf und/oder der Temperatur der Trocknungsluft und/oder der Temperaturverlauf der Trocknungsluft in der Trommel des Wäschetrockners zwischen Eintritt in die Trommel und Austritt aus der Trommel und/oder die Zeitdauer bis zum Erreichen eines Trockenziels verwendet werden.[027] To achieve the above goals, the laundry mass and / or the heating-up time and / or the laundry moisture content and / or the laundry moisture profile and / or the laundry conductivity value and / or the laundry conductivity value profile and / or the moisture content profile and / or the moisture content and / or or the course of moisture and / or the temperature of the laundry and / or the temperature profile of the laundry and / or the temperature of the drying air and / or the temperature course of the drying air in the drum of the tumble dryer and / or the comparison of the moisture content and / or Moisture profile and / or the temperature of the drying air and / or the temperature profile of the drying air in the drum of the tumble dryer between entry into the drum and exit from the drum and / or the period of time until a drying target is reached.
[028] Hierzu hat die drehbar Trommel während der Knitterschitzphase Drehbewegungszeitabschnitte und Stillstandszeitabschnitte. Während der Drehbewegungszeit- absd nitte der Trommel kann die Trommel in eine Drehrichtung gedreht werden und/ oder reversierend in unterschiedliche Drehri htungen gedreht werden. Die Dauer einer Knitterschitzphase beträgt bevorzugt ein bis fünf Stunden.[028] For this purpose, the rotatable drum has rotational movement periods and standstill periods during the crease phase. During the rotational movement time sections of the drum, the drum can be rotated in one direction of rotation and / or reversely rotated in different directions of rotation. The duration of a crease phase is preferably one to five hours.
[029] In einer bevorzugten Ausführung ist die Dauer der Knitterschitzphase in vier Zeitabschnitte unterteilt, wobei in einem ersten Zeitabschnitt die Bewegungsanteile zwischen 20% und 90% und in einem zweiten Zeitabschnitt die Bewegungsanteile zwischen 10% und 70% liegen und in einem dritten Bewegungsabschnitt die Bewegungsanteile zwischen 1% und 60% liegen und in einem vierten Zeitabschnitt die Bewegungsanteile zwischen 1% und 30% liegen. Insbesondere kann in einem ersten Zeitabschnitt die Trommelbewegung für 104 s ausgeschaltet und für 16 s eingeschaltet sein, und in einem zweiten Zeitabschnitt die Trommelbewegung für 284 s ausgeschaltet und für 16 s eingeschaltet sein und in einem dritten Zeitabschnitt die Trommelbewegung für 584 s ausgeschaltet und für 16 s eingeschaltet sein und einem vierten Zeitabschnitt die Trommelbewegung für 584 s ausgeschaltet und für 16 s eingeschaltet sein. Bei einem Verfahren zum Trocknen von Wäsche in einer Vorrichtung mit einer drehbaren Trommel (2) zum Bewegen der Wäsche ist im Anschluss an ein Trocknungsprogramm eine Knitterschitzphase vorgesehen, bei der die Wäsche zeitweise bewegt und zeitweise nicht bewegt wird. Diese Knittersdiitzphase dient dazu, das Fixieren von Knittern in der Wäsche durch regelmäßiges Auflockern der Wäsche zu vermeiden. Um Energie einzusparen und um die Wäsche und auch die Vorrichtung zu schonen wird die Wäsche im Verlauf der Knitterschitzphase minimal bewegt, sodass eine Knitterbildung gerade vermieden wird. [029] In a preferred embodiment, the duration of the crease phase is divided into four time segments, the movement components between 20% and 90% in a first time segment and between 10% and 70% in a second time segment and the movement components in a third time segment Movement shares are between 1% and 60% and in a fourth period the movement shares are between 1% and 30%. In particular, the drum movement can be switched off for 104 s and switched on for 16 s in a first time period be, and in a second period the drum movement is switched off for 284 s and switched on for 16 s and in a third period the drum movement is switched off for 584 s and switched on for 16 s and in a fourth period the drum movement is switched off for 584 s and for 16 s to be on. In a method for drying laundry in a device with a rotatable drum (2) for moving the laundry, a crease phase is provided following a drying program, in which the laundry is temporarily moved and temporarily not moved. This crease phase serves to prevent wrinkles from being fixed in the laundry by loosening the laundry regularly. In order to save energy and to protect the laundry and also the device, the laundry is moved minimally in the course of the crease phase, so that creasing is just avoided.
