Description

Die vorliegende Erfindung betrifft ein Wäschepflegegerät mit einer Steuerung.The present invention relates to a laundry care device with a controller.

In einem Wäschepflegegerät mit Umpumpsystem wird Waschflüssigkeit aus dem Laugenbehälter mittels einer Laugenpumpe abgepumpt, und die abgepumpte Waschflüssigkeit mittels der Laugenpumpe dem Laugenbehälter durch das Umpumpsystem erneut zugeführt, um die Wäsche in der Waschtrommel erneut mit Waschflüssigkeit zu benetzen. Nicht wassersaugende Wäschestücke neigen dazu in der Waschtrommel auf der Waschflüssigkeit zu schwimmen, wodurch die schwimmenden Wäschestücke durch die rotierende Waschtrommel nicht ausreichend bewegt werden. Dadurch können die nicht wassersaugenden und auf der Waschflüssigkeit schwimmenden Wäschestücke während eines Wäschepflegevorgangs unter Umständen nicht ausreichend gereinigt werden.In a laundry care device with a pumping system, washing liquid is pumped out of the tub by means of a drain pump, and the pumped washing liquid is fed back to the tub by the pumping system in order to rewet the laundry in the washing drum with washing fluid. Laundry items that do not absorb water tend to float on the washing liquid in the washing drum, as a result of which the floating laundry items are not sufficiently moved by the rotating washing drum. As a result, the items of laundry that do not absorb water and float on the washing liquid may not be adequately cleaned during a laundry care process.

Es ist die der Erfindung zugrundeliegende Aufgabe, ein Wäschepflegegerät anzugeben, bei dem ein wirksamer Wäschepflegeprozess der gesamten Wäsche ermöglicht wird.The object on which the invention is based is to provide a laundry care device in which an effective laundry care process for the entire laundry is made possible.

Diese Aufgabe wird durch die Gegenstände mit den Merkmalen nach den unabhängigen Ansprüchen gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche, der Beschreibung und der Zeichnungen.This object is achieved by the objects with the features according to the independent claims. Advantageous embodiments are the subject matter of the dependent claims, the description and the drawings.

Gemäß einem Aspekt wird die erfindungsgemäße Aufgabe durch ein Wäschepflegegerät mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit, einer Waschtrommel zur Aufnahme von Wäsche, einem Trommelantrieb zum Rotieren der Waschtrommel, wobei der Laugenbehälter eine Ablassöffnung und eine Einlassöffnung umfasst, wobei die Ablassöffnung mit der Einlassöffnung durch eine Leitung fluidtechnisch verbunden ist, wobei in der Leitung eine Laugenpumpe zum Pumpen von Waschflüssigkeit angeordnet ist, und einer Steuerung zum Steuern des Trommelantriebs und der Laugenpumpe, gelöst, wobei die Steuerung ausgebildet ist, die Laugenpumpe während eines Umpumpvorgangs zu aktivieren, um Waschflüssigkeit durch die Ablassöffnung aus dem Laugenbehälter in die Leitung zu pumpen, und die abgepumpte Waschflüssigkeit durch die Leitung und durch die Einlassöffnung erneut dem Laugenbehälter zuzuführen, und wobei die Steuerung ausgebildet ist, den Trommelantrieb während des Umpumpvorgangs zu aktivieren, um die Waschtrommel während eines Rotationszeitintervalls zu rotieren und die Wäsche mit der Waschtrommel in Kontakt zu bringen.According to one aspect, the object according to the invention is provided by a laundry care device with a tub for receiving washing liquid, a washing drum for receiving laundry, a drum drive for rotating the washing drum, the tub comprising a drain opening and an inlet opening, the drain opening being connected to the inlet opening by a Line is fluidically connected, a drain pump for pumping washing liquid being arranged in the line, and a control for controlling the drum drive and the drain pump, solved, the controller being designed to activate the drain pump during a pumping over process to wash liquid through the drain opening to pump from the tub into the line, and the pumped out washing liquid through feed the line and through the inlet opening again to the tub, and wherein the control is designed to activate the drum drive during the pumping over process in order to rotate the washing drum during a rotation time interval and to bring the laundry into contact with the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch das Rotieren der Waschtrommel während des Umpumpvorgangs auch nicht wassersaugende und damit schwimmende Wäscheteile mit der Waschtrommel in Kontakt gebracht werden. Dadurch kommt es zu einer vorteilhaften Benetzung, Durchfeuchtung und Verbesserung der Waschwirkung von nicht wassersaugenden Wäscheteilen, wie z.B. Wäschestücken aus Wolle oder Seide.This has the technical advantage that by rotating the washing drum during the pumping over process, laundry parts that are not water-sucking and therefore floating are also brought into contact with the washing drum. This results in beneficial wetting, moisture penetration and improvement of the washing effect of non-water-absorbent laundry items such as items made of wool or silk.

Bei der Aktivierung der Laugenpumpe durch die Steuerung wird zu Beginn des Umpumpvorgangs Waschflüssigkeit aus dem Laugenbehälter in die Leitung abgepumpt, so dass der Stand der Waschflüssigkeit in dem Laugenbehälter absinkt. Bei einem absinkenden Stand der Waschflüssigkeit in dem Laugenbehälter werden auch nicht wassersaugende und damit schwimmende Wäscheteile mit der Waschtrommel in Kontakt gebracht und anschließend die Wäscheteile während des Rotationszeitintervalls durch die rotierende Waschtrommel bewegt. Hierbei kann das Rotationszeitintervall ein beliebiges Zeitintervall des Umpumpvorgangs umfassen, wobei das Rotationszeitintervall alternativ die gesamte Dauer des Umpumpvorgangs umfassen kann. Die mit der rotierenden Waschtrommel in Kontakt stehenden Wäschestücke können somit von allen Seiten gleichmäßig befeuchtet werden.When the drain pump is activated by the control, washing liquid is pumped out of the tub into the line at the beginning of the pumping process, so that the level of the washing liquid in the tub drops. When the washing liquid level in the tub drops, even non-water-absorbent and therefore floating laundry items are brought into contact with the washing drum and the laundry items are then moved through the rotating washing drum during the rotation time interval. Here, the rotation time interval can comprise any time interval of the pumping over process, wherein the rotation time interval can alternatively comprise the entire duration of the pumping over process. The laundry items in contact with the rotating washing drum can thus be moistened evenly from all sides.

Die durch die Laugenpumpe in die Leitung abgepumpte Waschflüssigkeit wird durch die Einlassöffnung während des Umpumpens wieder erneut in den Laugenbehälter gepumpt, um die abgepumpte Waschflüssigkeit der Wäsche in der Waschtrommel erneut zuzuführen. Hierbei kann die erneut zugeführte Waschflüssigkeit, die mit der rotierenden Waschtrommel in Kontakt stehenden Wäscheteile besonders wirksam benetzen, da die Waschflüssigkeit die durch die rotierende Waschtrommel wirksam bewegten Wäscheteile von verschiedenen Seiten vorteilhaft benetzt kann. Dadurch kommt es zu einer verbesserten Durchfeuchtung der Wäscheteile und zu einer verbesserten Waschwirkung aufgrund einer verbesserten Durchflutung der Wäscheteile.The washing liquid pumped out into the line by the drain pump is pumped back into the tub again through the inlet opening during pumping in order to supply the pumped washing liquid to the laundry in the washing drum again. Here, the newly supplied washing liquid can particularly effectively wet the laundry items in contact with the rotating washing drum, since the washing liquid can advantageously wet the laundry items effectively moved by the rotating washing drum from different sides. This results in an improved moisture penetration of the laundry items and an improved washing effect due to an improved flow through the laundry items.

Somit lässt sich die Kombination des Umpumpvorgangs mit einem in Kontakt bringen der Wäscheteile an die Waschtrommel während der Rotation der Waschtrommel vorteilhaft zur schonenden und wirksamen Wäschepflege von empfindlichen und wenig benetzbaren Wäscheteilen, z.B. aus Wolle oder Seide, einsetzen.Thus, the combination of the pumping over process with bringing the laundry items into contact with the washing drum during the rotation of the washing drum can advantageously be used for gentle and effective laundry care of sensitive and less wettable laundry items, e.g. made of wool or silk.

Unter einem Wäschepflegegerät wird ein Gerät verstanden, welches zur Wäschepflege eingesetzt wird, wie z.B. eine Waschmaschine oder ein Wäschetrockner. Insbesondere wird unter solch einem Wäschepflegegerät ein Haushaltswäschepflegegerät verstanden. Also ein Wäschepflegegerät, welches im Rahmen der Haushaltsführung verwendet wird, und mit dem Wäsche in haushaltsüblichen Mengen behandelt wird.A laundry care device is understood to mean a device that is used for laundry care, such as a washing machine or a tumble dryer. In particular, such a laundry care device is understood to mean a household laundry care device. So a laundry care device, which is used in the context of housekeeping, and with which laundry is treated in household quantities.

In einer vorteilhaften Ausführungsform des Wäschepflegegeräts weist das Wäschepflegegerät eine Einspülschale zum Bereitstellen von Waschflüssigkeit auf, wobei die Einspülschale durch eine Zuführleitung mit dem Laugenbehälter fluidtechnisch verbunden ist, wobei die Steuerung ausgebildet ist, die Einspülschale zu aktivieren, um Waschflüssigkeit von der Einspülschale durch die Zuführleitung dem Laugenbehälter zuzuführen.In an advantageous embodiment of the laundry care device, the laundry care device has a dispensing bowl for providing washing liquid, the dispensing bowl being fluidically connected to the tub by a supply line, the control being designed to activate the washing-in bowl in order to transfer washing liquid from the washing-in bowl through the supply line Supply tub.

Dadurch wird der technische Vorteil erreicht, dass durch die mit dem Laugenbehälter fluidtechnisch verbundene Einspülschale ein wirksames Zuführen von Waschflüssigkeit aus der Einspülschale in den Laugenbehälter ermöglicht wird.This achieves the technical advantage that the induction bowl, which is fluidically connected to the tub, enables washing liquid to be effectively fed from the induction bowl into the tub.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist die Steuerung ausgebildet, die Einspülschale vor dem Umpumpvorgang und dem Rotationszeitintervall zu aktivieren, um Waschflüssigkeit dem Laugenbehälter bis zu einem Zuführpegel zuzuführen, wobei der Zuführpegel oberhalb einer Trommelunterseite der Waschtrommel angeordnet ist.In a further advantageous embodiment of the laundry care device, the control is designed to activate the dispensing bowl before the pumping over process and the rotation time interval in order to supply washing liquid to the tub up to a supply level, the supply level being arranged above a drum underside of the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch das Zuführen von Waschflüssigkeit bis zu dem Zuführpegel sichergestellt wird, dass die Waschtrommel bis zu einer ausreichenden Höhe mit Waschflüssigkeit in Kontakt steht. Der Zuführpegel der Waschflüssigkeit, welcher oberhalb der Trommelunterseite der Waschtrommel angeordnet ist, stellt somit sicher, dass die sich in der Waschtrommel befindende Wäsche bei einer Rotation der Waschtrommel ausreichend benetzt wird.This achieves the technical advantage that, by supplying washing liquid up to the supply level, it is ensured that the washing drum is in contact with washing liquid up to a sufficient height. The feed level of the washing liquid, which is arranged above the underside of the drum of the washing drum, thus ensures that the laundry located in the washing drum is sufficiently wetted when the washing drum rotates.

Gemäß der Erfindung ist die Steuerung ausgebildet, den Trommelantrieb zu aktivieren, um die Waschtrommel während des Rotationszeitintervalls zu rotieren, wenn die Waschflüssigkeit in dem Laugenbehälter einen Umpumppegel erreicht hat, wobei der Umpumppegel unterhalb einer Trommelunterseite der Waschtrommel angeordnet ist.According to the invention, the controller is designed to activate the drum drive in order to rotate the washing drum during the rotation time interval when the washing liquid in the tub has reached a pumped-over level, the pumped-over level being arranged below a drum underside of the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch die zeitlich verzögerte Aktivierung des Rotationszeitintervalls nach der Aktivierung des Umpumpvorgangs eine während des Rotationszeitintervalls bei hohen Rotationsdrehzahlen der Waschtrommel auftretende mechanische Belastung des Wäschepflegegeräts reduziert werden kann. Nach der Aktivierung des Umpumpvorgangs sinkt der Stand der Waschflüssigkeit in dem Laugenbehälter bis zu dem Umpumppegel unterhalb der Trommelunterseite der Waschtrommel ab, bevor anschließend das Rotationszeitintervall beginnt. Dadurch steht sowohl die Waschtrommel als auch die sich darin befindende Wäsche während des Rotationszeitintervalls nicht mehr mit der Waschflüssigkeit in Kontakt. Insbesondere sinkt dabei auch schwimmende Wäsche durch den sinkenden Waschflüssigkeitsstand in der Waschtrommel ab und kommt mit der Waschtrommel in Kontakt.This achieves the technical advantage that the delayed activation of the rotation time interval after activation of the pumping over process can reduce a mechanical load on the laundry care device occurring during the rotation time interval at high rotational speeds of the washing drum. After the activation of the pumping over process, the level of the washing liquid in the tub drops to the pumping over level below the drum underside of the washing drum, before the rotation time interval then begins. As a result, both the washing drum and the laundry located therein are no longer in contact with the washing liquid during the rotation time interval. In particular, floating laundry also sinks due to the falling washing liquid level in the washing drum and comes into contact with the washing drum.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist der Trommelantrieb ausgebildet, die Waschtrommel während des Rotationszeitintervalls mit einer Anlagedrehzahl anzutreiben, um die Wäsche mit der Waschtrommel in Anlage zu bringen, wobei die Anlagedrehzahl insbesondere einen Bereich von 50 U/min bis 150 U/min umfasst.In a further advantageous embodiment of the laundry care device, the drum drive is designed to drive the washing drum during the rotation time interval at a system speed in order to bring the laundry into contact with the washing drum, the system speed in particular encompassing a range from 50 rpm to 150 rpm .

Dadurch wird der technische Vorteil erreicht, dass bei einem Umpumppegel, welcher unterhalb einer Trommelunterseite der Waschtrommel angeordnet ist, die Waschtrommel mit einer Anlagedrehzahl angetrieben werden kann, ohne dass mechanische Belastungen durch den Kontakt der rotierenden Waschtrommel mit Waschflüssigkeit auftreten können, und somit mechanische Belastungen in dem Wäschepflegegerät reduziert werden können. Hierbei ist die Anlagedrehzahl ausreichend, um auch schwimmende Wäschestücke durch die während des Rotationsvorhangs auftretende Fliehkraft, wirksam mit der Waschtrommel in Anlage zu bringen. Dadurch kann die an der Waschtrommel anliegende Wäsche besonders wirksam durch die rotierende Waschtrommel mitgeführt werden, um eine vollständige Benetzung der Wäschestücke während des Umpumpvorgangs zu gewährleisten.This achieves the technical advantage that at a pump circulation level which is arranged below the underside of the drum of the washing drum, the washing drum can be driven at a system speed without mechanical loads occurring due to the contact of the rotating washing drum with washing liquid, and thus mechanical loads in the laundry care device can be reduced. Here, the system speed is sufficient to bring even floating items of laundry effectively into contact with the washing drum due to the centrifugal force occurring during the rotating curtain. As a result, the laundry lying on the washing drum can be carried along particularly effectively by the rotating washing drum to ensure complete wetting of the laundry during the pumping over process.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist die Steuerung ausgebildet, das Rotationszeitintervall zu beenden, wenn die zugeführte Waschflüssigkeit in dem Laugenbehälter einen Oberpegel erreicht hat, wobei der Oberpegel oberhalb der Trommelunterseite der Waschtrommel angeordnet ist.In a further advantageous embodiment of the laundry care device, the control is designed to end the rotation time interval when the supplied washing liquid has reached an upper level in the tub, the upper level being arranged above the underside of the washing drum.

Dadurch wird der technische Vorteil erreicht, dass während des Rotationszeitintervalls bei hohen Rotationsdrehzahlen auftretende mechanische Belastungen des Wäschepflegegeräts reduziert werden können. Ein ansteigender Waschflüssigkeitsstand in dem Laugenbehälter resultiert in einer erhöhten mechanischen Belastung des Wäschepflegegeräts bei einem Rotieren der Waschtrommel durch stehende Waschflüssigkeit.This has the technical advantage that mechanical loads on the laundry care appliance that occur during the rotation time interval at high rotation speeds can be reduced. A rising washing liquid level in the tub results in an increased mechanical load on the laundry care appliance when the washing drum rotates due to standing washing liquid.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts erfolgt das in Kontakt bringen der Wäsche mit der Waschtrommel während des Rotationszeitintervalls durch ein Absinken der Waschflüssigkeit in dem Laugenbehälter während des Umpumpvorgangs.In a further advantageous embodiment of the laundry care device, the laundry is brought into contact with the washing drum during the rotation time interval by the washing liquid falling in the tub during the pumping over process.

Dadurch wird der technische Vorteil erreicht, dass durch das Absinken der Waschflüssigkeit in dem Laugenbehälter auf der Waschflüssigkeit schwimmende Wäschestücke mit der Waschtrommel in Kontakt gebracht werden, ohne dass die Waschtrommel während des Rotationszeitintervalls mit einer hohen Rotationsdrehzahl rotiert wird. Während des Umpumpvorgangs wird Waschflüssigkeit aus dem Laugenbehälter abgepumpt, wodurch der Waschflüssigkeitstand in dem Laugenbehälter absinkt, so dass auf der Waschflüssigkeit schwimmende Wäschestücke mit der Waschtrommel in Kontakt gebracht werden. Wenn die Waschtrommel mit einer geringen Rotationsdrehzahl rotiert wird, dann werden die Wäschestücke vorteilhaft mit der Waschtrommel in Kontakt gebracht und dadurch wirksam gewendet. Im Rahmen des Umpumpvorgangs wird die abgepumpte Waschflüssigkeit dem Laugenbehälter erneut zugeführt, wodurch die mit der Waschtrommel in Kontakt stehenden und durch die Waschtrommel bewegten Wäschestücke wirksam von allen Seiten benetzt werden können.This achieves the technical advantage that items of laundry floating on the washing liquid are brought into contact with the washing drum due to the sinking of the washing liquid in the tub without the washing drum rotating at a high rotational speed during the rotation time interval. During the pumping over process, washing liquid is pumped out of the tub, as a result of which the washing liquid level in the tub drops so that items of laundry floating on the washing liquid are brought into contact with the washing drum. When the washing drum is rotated at a low rotational speed, the items of laundry are advantageously brought into contact with the washing drum and thereby effectively turned. As part of the pumping over process, the pumped-out washing liquid is fed back to the tub, whereby the items of laundry that are in contact with the washing drum and moved through the washing drum can be effectively wetted from all sides.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist die Steuerung ausgebildet, die Laugenpumpe und den Trommelantrieb gleichzeitig zu aktivieren, um den Umpumpvorgang und das Rotationszeitintervall gleichzeitig durchzuführen.In a further advantageous embodiment of the laundry care device, the control is designed to activate the drain pump and the drum drive at the same time in order to carry out the pumping over process and the rotation time interval at the same time.

Dadurch wird der technische Vorteil erreicht, dass durch das gleichzeitige Durchführen des Umpumpvorgangs und des Rotationszeitintervalls die Wäschestücke mit der Waschtrommel in Kontakt kommen und gleichzeitig wirksam durchfeuchtet werden, da zu Beginn des Umpumpvorgangs die Waschflüssigkeit noch in dem Laugenbehälter steht. Hierbei wird das Rotationszeitintervall insbesondere mit einer geringen Rotationsdrehzahl der Waschtrommel durchgeführt, um eine Beschädigung des Wäschepflegegeräts durch eine zu schnelle Rotation der Waschtrommel durch zu Beginn des Umpumpvorgangs noch mit der Waschtrommel in Kontakt stehender Waschflüssigkeit zu verhindern. Das gleichzeitig mit dem Umpumpvorgang gestartete Rotationszeitintervall kann die gesamte Dauer des Umpumpvorgangs umfassen, kann jedoch alternativ auch nur einen Teil des Umpumpvorgangs umfassen.This achieves the technical advantage that by simultaneously performing the pumping over process and the rotation time interval, the items of laundry come into contact with the washing drum and are effectively moistened at the same time, since the washing liquid is still in the tub at the beginning of the pumping over process. Here, the rotation time interval is carried out, in particular, with a low rotational speed of the washing drum in order to prevent damage to the laundry care device due to too fast rotation of the washing drum due to washing liquid still in contact with the washing drum at the beginning of the pumping over process. The rotation time interval started at the same time as the pumping process can encompass the entire duration of the pumping process, but can alternatively also comprise only a part of the pumping process.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist die Steuerung ausgebildet, nach Abschluss des Umpumpvorgangs und des Rotationszeitintervalls, die Einspülschale während eines Füllvorgangs zu aktivieren, um Waschflüssigkeit dem Laugenbehälter zuzuführen, wobei die Steuerung ausgebildet ist, den Trommelantrieb während des Füllvorgangs zu deaktivieren.In a further advantageous embodiment of the laundry care device, the control is designed to activate the dispensing bowl during a filling process after the pumping over process and the rotation time interval have been completed, in order to supply washing liquid to the tub, the control being designed to deactivate the drum drive during the filling process.

Dadurch wird der technische Vorteil erreicht, dass durch das Zuführen von zusätzlicher Waschflüssigkeit während des Füllvorgangs ein besonders wirksames Benetzen der Wäsche in der Waschtrommel sichergestellt wird, da der Pegel der Waschflüssigkeit in dem Laugenbehälter ansteigt. Durch das Deaktivieren des Trommelantriebs während des Füllvorgangs wird sichergestellt, dass die Waschtrommel bei einem ansteigenden Pegel der Waschflüssigkeit in dem Laugenbehälter nicht rotiert wird oder nur mit einer geringen Rotationsdrehzahl rotiert wird, wodurch durch mechanische Belastungen auftretende Beschädigungen des Wäschepflegegeräts verhindert werden können.This achieves the technical advantage that by supplying additional washing liquid during the filling process, particularly effective wetting of the laundry in the washing drum is ensured, since the level of the washing liquid in the tub increases. Deactivating the drum drive during the filling process ensures that the washing drum is not rotated when the washing liquid level rises in the tub or is only rotated at a low rotational speed, which can prevent damage to the laundry care device caused by mechanical loads.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist der Trommelantrieb ausgebildet, die Waschtrommel während des Rotationszeitintervalls um mindestens eine halbe Trommeldrehung zu rotieren, insbesondere um eine halbe oder eine volle Trommeldrehung zu rotieren.In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the washing drum by at least half a drum rotation during the rotation time interval, in particular to rotate a half or a full drum rotation.

Dadurch wird der technische Vorteil erreicht, dass durch die mindestens halbe Trommeldrehung, insbesondere eine halbe oder eine volle Trommeldrehung, der Waschtrommel während des Rotationszeitintervalls ein besonders wirksames Benetzen der mit der Waschtrommel in Kontakt stehenden Wäschestücke erreicht wird. Hierbei ist eine halbe Trommelumdrehung ausreichend, damit ein mit der Waschtrommel in Kontakt stehendes Wäschestück während eines Umpumpens von Waschlauge in dem Wäschepflegegerät von beiden Seiten benetzt werden kann.This achieves the technical advantage that particularly effective wetting of the laundry items in contact with the washing drum is achieved by the at least half a drum rotation, in particular a half or a full drum rotation, of the washing drum during the rotation time interval. Half a drum revolution is sufficient here so that an item of laundry that is in contact with the washing drum can be wetted from both sides while washing liquor is being pumped around in the laundry care appliance.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist der Trommelantrieb ausgebildet, die Waschtrommel während des Rotationszeitintervalls in einer Rotationsdrehrichtung oder reversierend zu rotieren.In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the washing drum in a rotational direction of rotation or in a reversing manner during the rotation time interval.

Dadurch wird der technische Vorteil erreicht, dass durch das Rotieren der Waschtrommel in der Rotationsdrehrichtung oder das reversierende Rotieren der Waschtrommel entgegen der Rotationsdrehrichtung an der Waschtrommel anliegende Wäsche während des Rotationszeitintervalls und während des Umpumpvorgangs wirksam benetzt werden kann.This has the technical advantage that by rotating the washing drum in the rotational direction of rotation or by rotating the washing drum reversely against the rotational direction of rotation, laundry lying on the washing drum can be effectively wetted during the rotation time interval and during the pumping over process.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist an der Einlassöffnung eine Zuführdüse angeordnet, wobei die Zuführdüse ausgebildet ist, durch die Einlassöffnung in den Laugenbehälter gepumpte Waschflüssigkeit über die Wäsche in der Waschtrommel zu streuen.In a further advantageous embodiment of the laundry care device, a feed nozzle is arranged at the inlet opening, the feed nozzle being designed to sprinkle washing liquid pumped into the tub through the inlet opening over the laundry in the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch die an der Einlassöffnung angeordnete Zuführdüse Waschflüssigkeit, welche durch die Leitung umgepumpt wird, wirksam über die Wäsche in der Waschtrommel gestreut werden kann. Während des Umpumpvorgangs stellt sich hierbei eine kontinuierliche Waschflüssigkeitszirkulation in dem Wäschepflegegerät ein, wodurch die umgepumpte Waschflüssigkeit an der Zuführdüse gestreut wird, und damit insbesondere breit gefächert die an der Waschtrommel anliegende Wäsche benetzen kann.This achieves the technical advantage that washing liquid, which is arranged at the inlet opening and which is pumped around through the line, can be effectively scattered over the laundry in the washing drum. During the pumping over process, a continuous washing liquid circulation is established in the laundry care device, whereby the pumping over washing liquid on the Feed nozzle is scattered, and thus in particular can wet the laundry lying on the washing drum in a wide range.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist die Steuerung ausgebildet, den Umpumpvorgang und das Rotationszeitintervall mehrmals zu wiederholen, insbesondere einmal, zweimal oder dreimal zu wiederholen.In a further advantageous embodiment of the laundry care device, the control is designed to repeat the pumping over process and the rotation time interval several times, in particular to repeat once, twice or three times.

Dadurch wird der technische Vorteil erreicht, dass durch das mehrmalige Wiederholen des Umpumpvorgangs und des Rotationszeitintervalls sichergestellt wird, dass alle in der Waschtrommel vorhandenen schwimmenden Wäschestücke mit der Waschtrommel in Kontakt kommen, und somit eine ausreichende Benetzung der schwimmenden Wäschestücke sichergestellt wird.This has the technical advantage that by repeating the pumping over process and the rotation time interval several times, it is ensured that all the floating items of laundry in the washing drum come into contact with the washing drum, thus ensuring adequate wetting of the floating items of laundry.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts umfasst die in der Waschtrommel aufgenommene Wäsche empfindliche Wäschestücke, insbesondere Wäschestücke aus Wolle und/oder aus Seide.In a further advantageous embodiment of the laundry care device, the laundry received in the washing drum comprises delicate laundry items, in particular laundry items made of wool and / or silk.

Dadurch wird der technische Vorteil erreicht, dass Wäschestücke aus Wolle und/oder Seide aufgrund deren Textileigenschaften auf der Waschflüssigkeit aufschwimmen, so dass während des Umpumpvorgangs und des Rotationszeitintervalls ein wirksamer Kontakt der Wäschestücke mit der Waschtrommel sichergestellt wird.This has the technical advantage that laundry items made of wool and / or silk float on the washing liquid due to their textile properties, so that effective contact of the laundry items with the washing drum is ensured during the pumping over process and the rotation time interval.

In einer weiteren vorteilhaften Ausführungsform des Wäschepflegegeräts ist in der Waschtrommel eine Anzahl von Vorsprüngen angeordnet, welche ausgebildet sind, die Wäsche während einer Rotation der Waschtrommel in der Waschtrommel zu bewegen.In a further advantageous embodiment of the laundry care device, a number of projections are arranged in the washing drum, which are designed to move the laundry in the washing drum during a rotation of the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch die Vorsprünge, welche insbesondere als Wäschemitnehmer ausgebildet sind, ein wirksames Bewegen von Wäschestücken in der rotierenden Waschtrommel sichergestellt wird. Die Vorsprünge sind insbesondere ausgebildet mit der Waschtrommel in Kontakt stehende Wäschestücke während des Rotationszeitintervalls wirksam zu bewegen.This achieves the technical advantage that the projections, which are designed in particular as laundry drivers, ensure that items of laundry are effectively moved in the rotating washing drum. The projections are in particular designed to move items of laundry in contact with the washing drum effectively during the rotation time interval.

Gemäß einem zweiten Aspekt der Erfindung wird die Aufgabe durch ein Verfahren zum Waschen von Wäsche in einem Wäschepflegegerät gelöst, mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit, mit einer Waschtrommel zur Aufnahme von Wäsche, mit einem Trommelantrieb zum Rotieren der Waschtrommel, wobei der Laugenbehälter eine Ablassöffnung und eine Einlassöffnung umfasst, wobei die Ablassöffnung mit der Einlassöffnung durch eine Leitung fluidtechnisch verbunden ist, wobei in der Leitung eine Laugenpumpe zum Pumpen von Waschflüssigkeit angeordnet ist, und mit einer Steuerung zum Steuern des Trommelantriebs und der Laugenpumpe, und wobei das Verfahren, das Aktivieren der Laugenpumpe während eines Umpumpvorgangs umfasst, um Waschflüssigkeit durch die Ablassöffnung aus dem Laugenbehälter in die Leitung zu pumpen, und die abgepumpte Waschflüssigkeit durch die Leitung und durch die Einlassöffnung erneut dem Laugenbehälter zuzuführen, und das Aktivieren des Trommelantriebs, um die Waschtrommel während eines Rotationszeitintervalls zu rotieren und die Wäsche mit der Waschtrommel in Kontakt zu bringen, umfasst.According to a second aspect of the invention, the object is achieved by a method for washing laundry in a laundry care device, with a tub for Receiving washing liquid, with a washing drum for receiving laundry, with a drum drive for rotating the washing drum, wherein the tub comprises a drain opening and an inlet opening, the drain opening being fluidically connected to the inlet opening by a line, wherein a drain pump for Pumping washing liquid is arranged, and with a controller for controlling the drum drive and the drain pump, and wherein the method comprises activating the drain pump during a pumping over process in order to pump washing liquid through the drain opening from the tub into the line, and the pumped washing liquid through the conduit and through the inlet opening again to the tub, and activating the drum drive to rotate the washing drum during a rotation time interval and to bring the laundry into contact with the washing drum.

Dadurch wird der technische Vorteil erreicht, dass durch das in Kontakt bringen der Wäsche mit der Waschtrommel während des Rotationszeitintervalls und des Umpumpens von Waschflüssigkeit während des Umpumpvorgangs, ein besonders wirksames Benetzen von in der Waschtrommel befindlichen auf der Waschflüssigkeit aufschwimmenden Wäschestücken erreicht wird.This has the technical advantage that by bringing the laundry into contact with the washing drum during the rotation time interval and pumping washing liquid during the pumping over process, particularly effective wetting of items of laundry in the washing drum floating on the washing liquid is achieved.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden näher beschrieben.Embodiments of the invention are shown in the drawings and are described in more detail below.

Fig. 1 zeigt eine schematische Ansicht eines allgemeinen Wäschepflegegeräts 100, wie z.B. eine Waschmaschine. Das Wäschepflegegerät 100 umfasst eine Einspülschale 101, in die Waschmittel oder andere flüssige Substanzen eingefüllt werden können. Das Wäschepflegegerät 100 umfasst eine Tür 103 zum Beladen des Wäschepflegegerätes 100 mit Wäsche. Fig. 1 FIG. 11 shows a schematic view of a general laundry care device 100, such as a washing machine. The laundry care device 100 comprises a rinsing bowl 101 into which detergent or other liquid substances can be filled. The laundry care device 100 comprises a door 103 for loading the laundry care device 100 with laundry.

Fig. 2 zeigt eine Ansicht eines Umpumpsystems in einem Wäschepflegegerät 100 mit einem Laugenbehälter 105 zur Aufnahme von Waschflüssigkeit, und mit einer Waschtrommel 107 zur Aufnahme von Wäsche. Die Waschtrommel 107 weist eine Trommelunterseite 109 auf und wird durch einen Trommelantrieb 111 angetrieben. Das Wäschepflegegerät 100 umfasst ferner eine Einspülschale 101 zur Aufnahme von Waschmittel oder anderen flüssigen Substanzen, welche mit dem Laugenbehälter 105 durch eine Zuführleitung 113 fluidtechnisch verbunden ist, um Waschflüssigkeit dem Laugenbehälter 105 zuzuführen. Fig. 2 shows a view of a pumping system in a laundry care device 100 with a tub 105 for receiving washing liquid, and with a washing drum 107 for receiving laundry. The washing drum 107 has an underside 109 of the drum and is driven by a drum drive 111. The laundry care device 100 further comprises a dispensing bowl 101 for receiving detergent or other liquid substances, which is fluidically connected to the tub 105 by a feed line 113 in order to feed washing liquid to the tub 105.

Der Laugenbehälter 105 weist eine Ablassöffnung 115 und eine Einlassöffnung 117 auf, welche durch eine Leitung 119 des Umpumpsystems fluidtechnisch verbunden sind, wobei in der Leitung 119 eine Laugenpumpe 121 zum Pumpen von Waschflüssigkeit durch die Leitung 119 angeordnet ist. Die Laugenpumpe 121 kann Waschflüssigkeit durch die Ablassöffnung 115 aus dem Laugenbehälter 105 während eines in Fig. 2 nicht dargestellten Umpumpvorgangs in die Leitung 119 abpumpen und die abgepumpte Waschflüssigkeit durch die Leitung 119 und durch die Einlassöffnung 117 dem Laugenbehälter 105 erneut zuführen. Dadurch kann die frische Waschflüssigkeit während eines Wäschepflegeprozesses wirksam durch die Leitung 119 umgepumpt werden und der Wäsche in der Waschtrommel 107 erneut zugeführt werden. Dadurch kann der Wäschepflegeerfolg während eines Wäschepflegeprozesses verbessert werden.The tub 105 has a drain opening 115 and an inlet opening 117, which are fluidically connected by a line 119 of the pumping system, a drain pump 121 for pumping washing liquid through the line 119 being arranged in the line 119. The drain pump 121 can dispense washing liquid through the drain opening 115 from the tub 105 during an in Fig. 2 Pump the pumping over process, not shown, into the line 119 and feed the pumped washing liquid through the line 119 and through the inlet opening 117 to the tub 105 again. As a result, the fresh washing liquid can be effectively pumped around through the line 119 during a laundry care process and fed back to the laundry in the washing drum 107. As a result, the laundry care success can be improved during a laundry care process.

Das Wäschepflegegerät 100 umfasst ferner eine Steuerung 123, welche mit der Laugenpumpe 121 durch eine erste Steuerverbindung 125 verbunden ist, welche mit dem Trommelantrieb 111 durch eine zweite Steuerverbindung 127 verbunden ist, und welche mit der Einspülschale 101 durch eine dritte Steuerverbindung 129 verbunden ist, um die Laugenpumpe 121, den Trommelantrieb 111 und die Einspülschale 101 zu aktivieren, bzw. zu deaktivieren. Die Steuerung 123 ist ausgebildet, die Laugenpumpe 121 während eines Umpumpvorgangs zu aktivieren, und den Trommelantrieb 111 während eines Rotationszeitintervalls zu aktivieren.The laundry care device 100 further comprises a controller 123, which is connected to the drain pump 121 by a first control connection 125, which is connected to the drum drive 111 by a second control connection 127, and which is connected to the dispensing bowl 101 by a third control connection 129 in order to activate or deactivate the drain pump 121, the drum drive 111 and the dispensing bowl 101. The controller 123 is designed to activate the drain pump 121 during a pumping over process and to activate the drum drive 111 during a rotation time interval.

Fig. 3 zeigt eine graphische Darstellung eines Waschvorgangs in einem Wäschepflegegerät gemäß einer Ausführungsform. Fig. 3 zeigt eine zeitliche Darstellung der Temperatur von Waschflüssigkeit, des zugeführten Volumens der Waschflüssigkeit, der Rotationsgeschwindigkeit der Waschtrommel 107, und der Pumpleistung der Laugenpumpe 121, welche alle entlang der Ordinatenachse 131 in Abhängigkeit der Zeit, welche entlang der Abszissenachse 133 angegeben ist, aufgetragen sind. Fig. 3 shows a graphic representation of a washing process in a laundry care device according to an embodiment. Fig. 3 shows a time representation of the temperature of washing liquid, the supplied volume of washing liquid, the speed of rotation of the washing drum 107, and the pumping capacity of the drain pump 121, all of which are plotted along the ordinate axis 131 as a function of the time indicated along the abscissa axis 133.

Die erste Kurve 135 zeigt den Verlauf der Temperatur der Waschflüssigkeit in dem Umpumpsystem des Wäschepflegegeräts 100. Die zweite Kurve 137 zeigt den Verlauf des zugeführten Volumens von Waschflüssigkeit in das Umpumpsystem des Wäschepflegegeräts 100. Die dritte Kurve 139 zeigt den Verlauf der Rotationsgeschwindigkeit der Waschtrommel 107. Die vierte Kurve 141 zeigt den Verlauf der Pumpleistung der Laugenpumpe 121.The first curve 135 shows the profile of the temperature of the washing liquid in the pumping system of the laundry care device 100. The second curve 137 shows the profile of the volume of washing liquid supplied into the pumping system of the laundry care device 100. The third curve 139 shows the profile of the speed of rotation of the washing drum 107. The fourth curve 141 shows the course of the pumping capacity of the drain pump 121.

Wie in der zweiten Kurve 137 dargestellt ist, wird die Einspülschale 101 vor einem Umpumpvorgang und vor einem Rotationszeitintervall der Waschtrommel 107 durch die Steuerung 123 aktiviert, um Waschflüssigkeit dem Laugenbehälter 105 zuzuführen. Hierbei wird Waschflüssigkeit dem Laugenbehälter 105 so lange zugeführt, bis die Waschflüssigkeit in dem Laugenbehälter 105 einen Zuführpegel aufweist, wobei der Zuführpegel höher als eine Trommelunterseite 109 der Waschtrommel 107 ist, und wobei der Zuführpegel ausreichend ist um den Laugensumpf unterhalb des Laugenbehälters 105 zu bedecken und insbesondere 1 cm bis 3 cm höher als die Trommelunterseite 109 ist.As shown in the second curve 137, the induction bowl 101 is activated by the controller 123 before a pumping over process and before a rotation time interval of the washing drum 107 in order to supply washing liquid to the tub 105. In this case, washing liquid is fed to the tub 105 until the washing liquid in the tub 105 has a feed level, the feed level being higher than a drum bottom 109 of the washing drum 107, and the feed level being sufficient to cover the tub below the tub 105 and in particular 1 cm to 3 cm higher than the underside of the drum 109.

Wie in der vierten Kurve 141 dargestellt ist, wird zu Beginn des Umpumpvorgangs die Laugenpumpe 121 durch die Steuerung 123 aktiviert, wodurch Waschflüssigkeit aus dem Laugenbehälter 105 abgepumpt wird, und der Waschflüssigkeitsstand in dem Laugenbehälter 105 sinkt. Hierbei erreicht der Waschflüssigkeitsstand nach dem Aktivieren der Laugenpumpe 121 einen Umpumppegel, wobei der Umpumppegel unterhalb der Trommelunterseite 109 der Waschtrommel 107 in dem Laugenbehälter 105 angeordnet ist, so dass die Wäsche in der Waschtrommel 107 nicht mehr mit Waschflüssigkeit in Kontakt steht.As shown in fourth curve 141, at the beginning of the pumping over process, the drain pump 121 is activated by the controller 123, whereby washing liquid is pumped out of the tub 105 and the washing liquid level in the tub 105 drops. Here, the washing liquid level reaches after Activate the drain pump 121 to a pump circulation level, the pump circulation level being arranged below the drum underside 109 of the washing drum 107 in the solution container 105, so that the laundry in the washing drum 107 is no longer in contact with washing liquid.

Wie in der dritten Kurve 139 dargestellt ist, wird nach dem Aktivieren der Laugenpumpe 121, wenn der Waschflüssigkeitsstand in dem Laugenbehälter 105 den Umpumppegel erreicht hat, der Trommelantrieb 111 durch die Steuerung 123 aktiviert, um die Waschtrommel 107 mit einer Anlagedrehzahl zu rotieren, und die Wäsche an der Waschtrommel 107 in Anlage zu bringen. Hierbei kann die Anlagedrehzahl insbesondere in einem Bereich zwischen 50 U/min und 150 U/min liegen, wodurch aufgrund der dabei auftretenden Fliehkräfte eine wirksame Zwischenentwässerung der an der Waschtrommel 107 anliegenden Wäsche während des Rotationszeitintervalls herbeigeführt werden kann.As shown in the third curve 139, after activating the drain pump 121, when the washing liquid level in the tub 105 has reached the pumping over level, the drum drive 111 is activated by the controller 123 in order to rotate the washing drum 107 at a system speed, and the Bringing laundry to the washing drum 107 in the plant. The system speed can in particular be in a range between 50 rpm and 150 rpm, whereby, due to the centrifugal forces that occur, effective intermediate drainage of the laundry lying against the washing drum 107 can be brought about during the rotation time interval.

In dem Wäschepflegegerät 100 mit Umpumpsystem wird durch ein kurzzeitiges Rotieren der Waschtrommel 107 mit der Anlegedrehzahl die Wäsche dazu gebracht an der Waschtrommel 107 anzuliegen, um eine Zwischenentwässerung im Waschen herbeizuführen.In the laundry care device 100 with a pumping system, the laundry is caused to lie against the washing drum 107 by briefly rotating the washing drum 107 at the application speed in order to bring about intermediate drainage during washing.

Während des Umpumpvorgangs wird die durch die Laugenpumpe 121 aus dem Laugenbehälter 105 in die Leitung 119 abgepumpte Waschflüssigkeit dem Laugenbehälter 105 durch die Einlassöffnung 117 erneut zugeführt, so dass sich in der Leitung 119 während des Umpumpvorgangs eine kontinuierliche Waschflüssigkeitszirkulation einstellt. Hierbei wird die durch die Einlassöffnung 117 in den Laugenbehälter 105 gepumpte Waschflüssigkeit als ein Wasserstrahl auf die an der Waschtrommel 107 während des Rotationszeitintervalls anliegenden Wäscheteile geleitet, wobei der Wasserstrahl insbesondere breit über den Mantel der Waschtrommel 107 gefächert wird, um die Textilien wirksam zu benetzen. Somit kommt es zu einer optimierten Durchfeuchtung der an der Waschtrommel 107 anliegenden Wäsche und zu einer Verbesserung der Waschwirkung durch eine wirksame Durchflutung der Wäsche.During the pumping over process, the washing liquid pumped out of the tub 105 into the line 119 by the drain pump 121 is again supplied to the tub 105 through the inlet opening 117, so that a continuous washing liquid circulation is established in the line 119 during the pumping over process. The washing liquid pumped through the inlet opening 117 into the tub 105 is directed as a water jet onto the laundry items resting on the washing drum 107 during the rotation time interval, the water jet being particularly fanned out over the jacket of the washing drum 107 in order to effectively wet the textiles. This results in an optimized moisture penetration of the laundry lying against the washing drum 107 and an improvement in the washing effect through effective flooding of the laundry.

Wie in der dritten Kurve 139 und der vierten Kurve 141 zu erkennen ist, wird anschließend die Rotationsgeschwindigkeit der Waschtrommel 107 wieder reduziert, um das Rotationszeitintervall zu beenden. Anschließend wird die Laugenpumpe 121 deaktiviert, um den Umpumpvorgang zu beenden. Die Dauer des Umpumpvorgangs und des Rotationszeitintervalls kann in Abhängigkeit von der Wäschemenge, der Wäscheart und/oder des gewählten Wäschepflegeprogramms zeitlich flexibel ausgeführt werden, und gegebenenfalls ein, zwei oder dreimal wiederholt werden.As can be seen in the third curve 139 and the fourth curve 141, the rotation speed of the washing drum 107 is then reduced again in order to end the rotation time interval. The drain pump 121 is then deactivated, to end the pumping process. Depending on the amount of laundry, the type of laundry and / or the selected laundry care program, the duration of the pumping over process and the rotation time interval can be carried out flexibly in terms of time, and if necessary repeated one, two or three times.

Wie in der zweiten Kurve 137 dargestellt ist, wird bei einer nicht rotierenden Waschtrommel 107 die Einspülschale 101 erneut durch die Steuerung 123 aktiviert, um während eines Füllvorgangs erneut Waschflüssigkeit dem Laugenbehälter 105 zuzuführen. Durch den Füllvorgang steigt hierbei der Waschflüssigkeitspegel in dem Laugenbehälter 105 erneut an, so dass die Waschtrommel 107 und die sich darin befindliche Wäsche erneut mit der Waschflüssigkeit in Kontakt steht. Dabei kann der Stand der Waschflüssigkeit sukzessive durch weitere Füllschritte erhöht werden, und die Laugenpumpe 121 erneut aktiviert werden, um Waschflüssigkeit in dem Wäschepflegegerät 100 umzupumpen. Sobald der Waschflüssigkeitsstand bei der erneuten Aktivierung der Laugenpumpe 121 sich oberhalb der Trommelunterseite 109 der Waschtrommel 107 befindet, und somit die Wäsche mit der Waschflüssigkeit in Kontakt steht, wird der Trommelantrieb 111 durch die Steuerung 123 erneut aktiviert. Hierbei rotiert der Trommelantrieb 111 die Waschtrommel 107 jedoch nicht mit der Anlagedrehzahl, sondern nur mit einer geringen Rotationsdrehzahl. Dadurch wird verhindert, dass das Schwingsystem, welches den Laugenbehälter 105 stabilisiert, sich heftig bewegt, was zu starken mechanischen Belastungen des Wäschepflegegeräts führen kann. Zum anderen wird das Schrumpfen von empfindlichen Wäschestücken aus Wolle vermieden.As shown in the second curve 137, if the washing drum 107 is not rotating, the dispensing bowl 101 is activated again by the controller 123 in order to supply washing liquid to the tub 105 again during a filling process. As a result of the filling process, the washing liquid level in the tub 105 rises again, so that the washing drum 107 and the laundry located therein are again in contact with the washing liquid. The level of the washing liquid can be successively increased by further filling steps, and the drain pump 121 can be activated again in order to pump washing liquid in the laundry care device 100. As soon as the washing liquid level is above the drum underside 109 of the washing drum 107 when the drain pump 121 is activated again, and the laundry is thus in contact with the washing liquid, the drum drive 111 is activated again by the controller 123. In this case, however, the drum drive 111 does not rotate the washing drum 107 at the system speed, but only at a low rotational speed. This prevents the oscillating system, which stabilizes the tub 105, from moving violently, which can lead to strong mechanical loads on the laundry care appliance. On the other hand, the shrinking of delicate items made of wool is avoided.

Fig. 4 zeigt eine graphische Darstellung eines Waschvorgangs in einem Wäschepflegegerät gemäß einer weiteren Ausführungsform. Fig. 4 zeigt eine zeitliche Darstellung der Temperatur von Waschflüssigkeit, des zugeführten Volumens der Waschflüssigkeit, der Rotationsgeschwindigkeit der Waschtrommel 107, und der Pumpleistung der Laugenpumpe 121, welche entlang der Ordinatenachse 131 in Abhängigkeit der Zeit, welche entlang der Abszissenachse 133 angegeben ist, aufgetragen sind. Fig. 4 shows a graphic representation of a washing process in a laundry care device according to a further embodiment. Fig. 4 shows a time representation of the temperature of washing liquid, the supplied volume of washing liquid, the speed of rotation of the washing drum 107, and the pumping power of the drain pump 121, which are plotted along the axis of ordinate 131 as a function of the time indicated along the axis of abscissa 133.

Die erste Kurve 135 zeigt den Verlauf der Temperatur der Waschflüssigkeit in dem Umpumpsystem des Wäschepflegegeräts 100. Die zweite Kurve 137 zeigt den Verlauf des zugeführten Volumens von Waschflüssigkeit in das Umpumpsystem des Wäschepflegegeräts 100. Die dritte Kurve 139 zeigt den Verlauf der Rotationsgeschwindigkeit der Waschtrommel 107. Die vierte Kurve 141 zeigt den Verlauf der Pumpleistung der Laugenpumpe 121.The first curve 135 shows the course of the temperature of the washing liquid in the pumping system of the laundry care device 100. The second curve 137 shows the course of the supplied volume of washing liquid into the pumping system of the laundry care device 100. The third curve 139 shows the course of the rotational speed of the washing drum 107. The fourth curve 141 shows the course of the pumping capacity of the lye pump 121.

Entsprechend der in Fig. 3 dargestellten Ausführungsform wird wie gemäß der zweiten Kurve 137 dargestellt ist, vor einem Umpumpvorgang und vor einem Rotationszeitintervall der Waschtrommel 107 Waschflüssigkeit dem Laugenbehälter 105 so lange zugeführt, bis die Waschflüssigkeit in dem Laugenbehälter 105 einen Zuführpegel aufweist, wobei der Zuführpegel höher als eine Trommelunterseite 109 der Waschtrommel 107 ist, und insbesondere 1 cm bis 3 cm höher als die Trommelunterseite 109 ist.According to the in Fig. 3 As shown in the second curve 137, before a pumping over process and before a rotation time interval of the washing drum 107, washing liquid is supplied to the tub 105 until the washing liquid in the tub 105 has a supply level, the supply level being higher than a drum bottom 109 of the Washing drum 107 is, and in particular 1 cm to 3 cm higher than the drum bottom 109 is.

Wie in der vierten Kurve 141 dargestellt ist, wird zu Beginn des Umpumpvorgangs Waschflüssigkeit aus dem Laugenbehälter 105 abgepumpt. Hierbei sinkt während des Umpumpvorgangs die Waschflüssigkeit in dem Laugenbehälter ab, wobei dadurch auf der Waschflüssigkeit schwimmende Wäschestücke mit der Waschtrommel in Kontakt gebracht werden.As shown in the fourth curve 141, washing liquid is pumped out of the tub 105 at the beginning of the pumping over process. In this case, the washing liquid sinks in the tub during the pumping over process, whereby items of laundry floating on the washing liquid are brought into contact with the washing drum.

Während des Umpumpvorgangs wird der Trommelantrieb 111 durch die Steuerung 123 aktiviert, wodurch die Waschtrommel 107 mit einer geringen Rotationsdrehzahl rotiert wird, um die Wäsche in der Waschtrommel 107 bei geringem Wasserstand zu wenden. In Wäschepflegeprogrammen für typischerweise aufschwimmende Wäscheteile, wie z.B. in einem Programm für Wollstücke, wird somit die Waschtrommel 107 immer dann bewegt, wenn die Laugenpumpe 121 während des Umpumpvorgangs aktiviert ist. Während des Umpumpvorgangs sinkt der Waschflüssigkeitsstand in dem Laugenbehälter 105, die Wäsche steht mit der Waschtrommel 107 in Kontakt, und die Waschtrommel 107 dreht sich mindestens um eine halbe Trommelumdrehung, insbesondere mindestens einmal um 180°, wodurch die Wäsche gewendet wird. In Abhängigkeit von der Empfindlichkeit der Textilien kann auch ein mehrmaliges Wenden der Textilien mit einer Einschaltdauer von 33 % bei Wolle vorzugsweise unidirektional und bei Seide vorzugsweise reversierend genutzt werden.During the pumping over process, the drum drive 111 is activated by the controller 123, whereby the washing drum 107 is rotated at a low rotational speed in order to turn the laundry in the washing drum 107 when the water level is low. In laundry care programs for items of laundry that typically float up, such as, for example, in a program for pieces of wool, the washing drum 107 is therefore always moved when the drain pump 121 is activated during the pumping over process. During the pumping over process, the washing liquid level in the tub 105 sinks, the laundry is in contact with the washing drum 107, and the washing drum 107 rotates at least half a drum revolution, in particular at least once by 180 °, whereby the laundry is turned. Depending on the sensitivity of the textiles, repeated turning of the textiles with a duty cycle of 33% can be used, preferably unidirectional for wool and preferably reversing for silk.

Während des Umpumpvorgangs wird ferner die durch die Laugenpumpe 121 aus dem Laugenbehälter 105 in die Leitung 119 abgepumpte Waschflüssigkeit dem Laugenbehälter 105 durch die Einlassöffnung 117 erneut zugeführt, so dass sich in der Leitung 119 während des Umpumpvorgangs eine kontinuierliche Waschflüssigkeitszirkulation einstellt. Hierbei wird die durch die Einlassöffnung 117 in den Laugenbehälter 105 gepumpte Waschflüssigkeit als ein Wasserstrahl auf die in der Waschtrommel 107 befindlichen Wäscheteile geleitet, wobei der Wasserstrahl insbesondere breit über den Mantel der Waschtrommel 107 gefächert wird, um die Textilien wirksam zu benetzen.During the pumping over process, the washing liquid pumped out of the tub 105 into the line 119 by the drain pump 121 is also dem Lye container 105 is supplied again through the inlet opening 117, so that a continuous washing liquid circulation is established in the line 119 during the pumping over process. The washing liquid pumped through the inlet opening 117 into the tub 105 is directed as a water jet onto the laundry items in the washing drum 107, with the water jet being fanned out over the jacket of the washing drum 107 in order to effectively wet the textiles.

Die Dauer des Umpumpvorgangs mit Wenden kann zeitlich flexibel ausgestaltet werden und dabei gegebenenfalls einmal bis dreimal wiederholt werden. Dabei kann der Stand der Waschflüssigkeit in dem Laugenbehälter 105 durch sukzessive weitere Füllschritte erhöht werden.The duration of the pumping over process with turning can be flexible in terms of time and can be repeated once to three times if necessary. The level of the washing liquid in the tub 105 can be increased by successively further filling steps.

Sobald sich der Waschflüssigkeitsstand sich jedoch mehr als 1 cm bis 3 cm oberhalb der Trommelunterseite 109 der Waschtrommel 107 befindet, und somit die Wäsche mit der Waschflüssigkeit in Kontakt steht, wird jedoch der Trommelantrieb 111 durch die Steuerung 123 so gesteuert, dass keine Rotation der Waschtrommel 107 durchgeführt wird, bzw. nur eine geringe Rotation der Waschtrommel 107 durchgeführt wird. Dadurch wird verhindert, dass empfindliche Wäschestücken aus Wolle, schrumpfen.However, as soon as the washing liquid level is more than 1 cm to 3 cm above the drum bottom 109 of the washing drum 107 and the laundry is in contact with the washing liquid, the drum drive 111 is controlled by the controller 123 so that the washing drum does not rotate 107 is carried out, or only a slight rotation of the washing drum 107 is carried out. This prevents delicate items made of wool from shrinking.

In Wäschepflegegeräten 100 mit Umpumpsystem wird die Waschflüssigkeit durch die Laugenpumpe 121 aus dem Laugenbehälter 105 abgepumpt und die abgepumpte Waschflüssigkeit wird durch die Einlassöffnung 117 von oben wieder der Wäsche in der Waschtrommel 107 zugeführt. Hierbei wird die Laugenpumpe 121 zyklisch eingeschaltet. Während die Laugenpumpe 121 aktiviert ist, sinkt der Waschflüssigkeitsstand in der Waschtrommel 107, so dass bei einer geringen Menge von Waschflüssigkeit in dem Laugenbehälter 105 auch schwimmende Wäscheteile mit der Waschtrommel 107 in Kontakt gebracht werden.In laundry care devices 100 with a pumping system, the washing liquid is pumped out of the tub 105 by the lye pump 121 and the washing liquid pumped out is fed back to the laundry in the washing drum 107 through the inlet opening 117 from above. In this case, the drain pump 121 is switched on cyclically. While the drain pump 121 is activated, the washing liquid level in the washing drum 107 drops, so that when there is a small amount of washing liquid in the tub 105, floating laundry items are also brought into contact with the washing drum 107.

Die Kombination von Umpumpen, welche eine Absenkung des Waschflüssigkeitsstandes in dem Laugenbehälter 105 und eine Befeuchtung der Wäsche in der Waschtrommel 107 durch eine Zirkulation der Waschflüssigkeit in dem Umpumpsystem beinhaltet, mit dem Rotieren der Waschtrommel während des Rotationszeitintervalls, führt zu einer schonenden aber effektiven Bewegung und Reinigung von empfindlichen, wenig benetzbaren Textilien, wie z.B. Wolle oder Seide.The combination of pumping, which includes a lowering of the washing liquid level in the tub 105 and a moistening of the laundry in the washing drum 107 by a circulation of the washing liquid in the pumping system, with the rotation of the washing drum during the rotation time interval, leads to a gentle but effective movement and cleaning of sensitive, less wettable textiles such as wool or silk.

Die Kombination des Umpumpvorgangs und des Rotationszeitintervalls ermöglicht eine verbesserte Durchfeuchtung schlecht benetzbarer Textilien durch eine Befeuchtung der Textilien von allen Seiten durch umgepumpte Waschflüssigkeit. Hier werden insbesondere sich ändernde Füllstände von Waschflüssigkeit in der Waschtrommel 107 genutzt, wodurch auf der Waschflüssigkeit aufschwimmende Wäschestücke mit der Waschtrommel 107 in Kontakt gebracht werden können. Durch eine optimale Modulation der durch die Einführöffnung des Laugenbehälters 105 erneut zugeführten Waschflüssigkeit wird eine vorteilhafte Wäschepflege im Rahmen eines vertikalen Waschvorgangs ermöglicht.The combination of the pumping over process and the rotation time interval enables improved wetting of poorly wettable textiles by moistening the textiles from all sides by pumping washing liquid. Here, in particular, changing fill levels of washing liquid in the washing drum 107 are used, as a result of which laundry items floating on the washing liquid can be brought into contact with the washing drum 107. Optimal modulation of the washing liquid supplied again through the introduction opening of the tub 105 enables advantageous laundry care in the context of a vertical washing process.

Fig. 5 zeigt eine schematische Darstellung eines Verfahrens 200 zum Waschen von Wäsche in einem Wäschepflegegerät 100, welche gemäß der Ausführungsformen der Fig. 3 und Fig. 4 beschrieben ist. Fig. 5 FIG. 14 shows a schematic illustration of a method 200 for washing laundry in a laundry care device 100, which according to the embodiments of FIG Fig. 3 and Fig. 4 is described.

Das Verfahren 200 umfasst das Aktivieren 201 der Laugenpumpe 121 während eines Umpumpvorgangs, um Waschflüssigkeit durch die Ablassöffnung 115 aus dem Laugenbehälter 105 in die Leitung 119 zu pumpen, und die abgepumpte Waschflüssigkeit durch die Leitung 119 und durch die Einlassöffnung 117 erneut dem Laugenbehälter 105 zuzuführen. Das Verfahren 200 umfasst ferner das Aktivieren 203 des Trommelantriebs 111, um die Waschtrommel 107 während eines Rotationszeitintervalls zu rotieren und die Wäsche mit der Waschtrommel 107 in Kontakt zu bringen.The method 200 comprises activating 201 the drain pump 121 during a pumping over process in order to pump washing liquid through the drain opening 115 from the tub 105 into the line 119, and to supply the pumped washing liquid again through the line 119 and through the inlet opening 117 to the tub 105. The method 200 further comprises activating 203 the drum drive 111 in order to rotate the washing drum 107 during a rotation time interval and to bring the laundry into contact with the washing drum 107.

Dadurch kann ein besonders wirksames Waschen von in der Waschflüssigkeit aufschwimmenden Wäschestücken erreicht werden.In this way, particularly effective washing of items of laundry floating in the washing liquid can be achieved.

    the activation (201) of the drum drive (111), in order to rotate the laundry drum (107) during a rotation time interval and to bring the laundry into contact with the laundry drum (107), characterised in that the drum drive (111) is activated, in order to rotate the laundry drum (107) during the rotation time interval, when the washing liquid has reached a recirculating pumping level in the outer tub (105), wherein the recirculating pumping level is arranged below a drum underside (109) of the laundry drum (107), so that following the activation of the recirculating pumping procedure the level of the washing liquid in the outer tub (105) falls to the recirculating pumping level below the drum underside (109) of the washing drum (107) and the floating laundry falls due to the dropping level of the washing liquid in the laundry drum (107), before the rotation time interval then begins.
