Description
Die Erfindung betrifft eine Trommelwaschmaschine gemäß dem
Oberbegriff des Anspruches 1 sowie ein Verfahren zum Betreiben
einer Trommelwaschmaschine während des Spülbetriebes.The invention relates to a drum washing machine according to the
Preamble of
Moderne Trommelwaschmaschinen sind insbesondere aus Umweltschutzgründen, aber auch aus Energie- und Verbrauchergründen äußerst sparsam in ihrem Wässerverbrauch auszulegen. Das heißt, bei den wasserverbrauchenden Schritten soll die benötigte Wassermenge möglichst gering sein. Einen derartigen Schritt stellt der Spülbetrieb, im Rahmen dessen nach Durchführung des eigentlichen Waschbetriebs die in der Trommel angeordnete Wäsche, die Waschmittelreste beinhaltet, reingespült werden soll, dar. Trotz versuchter Minimierung des Brauchwassers darf dabei aber das Spülergebnis nicht minderwertig sein, das heißt, es muß sichergestellt werden, daß sämtliches rückständiges Waschmittel und natürlich etwaiger Schmutz aus der Wäsche ausgespült wird. Hierfür sind unterschiedliche Spülarten bekannt. Diese beinhalten sowohl Spülverfahren mit freier Flotte, als auch solche ohne freier Flotte.Modern drum washing machines are particularly for environmental reasons, but also for energy and consumer reasons extremely economical in their water consumption. That means that in the water-consuming steps required amount of water should be as small as possible. Such The rinsing operation adjusts to this step Carrying out the actual washing operation in the Drum arranged laundry containing detergent residues should be rinsed in. Despite attempted minimization of the process water, however, the washing result not be inferior, that is, it must be ensured be that any residual detergent and of course any dirt is washed out of the laundry. Therefor different types of flushing are known. These include both flushing process with free liquor, as well as such without a free fleet.
Beispielsweise lassen sich über die Art der Einbringung des Wassers sowohl der Wasserverbrauch beim Spülen als auch das Spülergebnis beeinflussen. So offenbart die EP 0 644 290 A1 eine Waschmaschine, bei der ein Teil des Spülwassers in die Trommel eingesprüht oder eingespritzt wird und erst nach dem damit erreichten ersten Durchfeuchten die restliche Frischwassermenge mittels einer Einspüleinrichtung zugeführt wird.For example, the type of introduction of the Water both the water consumption when rinsing and that Influence the washing result. For example, EP 0 644 290 A1 discloses a washing machine, in which a part of the rinse water in the Drum is sprayed or injected and only after the rest of the first moisturization achieved Fresh water quantity supplied by means of a flushing device becomes.
Die GB 2 276 394 offenbart eine Waschmaschine bei der für
den Spülvorgang abhängig von der Wäschemenge bzw. deren
Verschmutzung und/oder der Beschaffenheit der Wäsche einer
von zwei verschiedenen Spülmodi ausgewählt wird. Dabei wird
bei einer geringen Wäschemenge bzw. bei weniger stark verschmutzter
Wäsche ein Spülmodus gewählt, bei dem das Spülen
bei gleichzeitigem Wasserentzug durch Schleudern erfolgt
und hierdurch im Vergleich zu einem Spülbetrieb mit freier
Flotte die Spülwassermenge verringert wird.
Aus der GB 2 219 603 ist ein Spülverfahren einer Waschmaschine bekannt, bei dem zunächst ein Wäschering durch Einstellen einer Schleuderdrehzahl an der Wäschetrommel erzeugt und anschließend die Innenseite dieses Wäscheringes mit Spülflüssigkeit mittels einer Einsprühvorrichtung besprüht wird. Die aufgebrachte Spülflüssigkeit wird durch den Wäschering hindurch geschleudert und nimmt dabei Waschmittel- und Schmutzreste aus dem Wäschering mit. Die hindurch geschleuderte und mit Waschmittel- und Schmutzresten angereicherte Spülflüssigkeit wird kontinuierlich abgepumpt.GB 2 219 603 describes a washing process for a washing machine known, in which first a laundry ring by adjusting a spin speed generated on the laundry drum and then the inside of this laundry ring sprayed with rinsing liquid using a spray device becomes. The applied rinsing liquid is washed through hurled through the laundry ring, taking detergent and dirt residues from the laundry ring. The through flung and with detergent and dirt residues Enriched rinsing liquid is pumped out continuously.
Der Erfindung liegt das Problem zugrunde, eine Trommelwaschmaschine und ein Verfahren zum Betreiben einer Trommelwaschmaschine während eines Spülbetriebes anzugeben, durch die ein besonders niedriger Wasserverbrauch bei gleichzeitig guter Spülwirkung eingestellt ist.The invention is based on the problem of a drum washing machine and a method of operating a drum washing machine to indicate during a flushing operation through which a particularly low water consumption good rinsing effect is set at the same time.
Die Lösung dieses Problems erfolgt bei einer Trommelwaschmaschine
gemäß den Merkmalen des Oberbegriffs von Anspruch
1 durch die kennzeichnenden Merkmale dieses Anspruchs.
Die Lösung hinsichtlich des Verfahrens erfolgt
durch die Merkmale des Anspruchs 8.This problem is solved in a drum washing machine
according to the features of the preamble of
Die erfindungsgemäße Trommelwaschmaschine realisiert also mit besonderem Vorteil die Möglichkeit eines selektiven Spülbetriebs. Es hat sich nämlich als für eine Wassereinsparung bei gleichzeitiger Gewährleistung einer guten Spülwirkung als vorteilhaft erwiesen, wenn abhängig von der eingeladenen Wäschemenge bzw. der Wäscheart und der numerischen Anzahl des anstehenden Spülgangs die Auswahl des Spülprogramms erfolgt, wobei dieses dann den entsprechenden Parametern hinsichtlich des einzuspülenden Wassers und beispielsweise der Spüldauer entsprechend angepaßt ist. Denn beispielsweise bei großer Wäschemenge sind etwas größere Frischwassermengen erforderlich, wobei aber bei beispielsweise dem zweiten Spülgang die Wäsche ohnehin bereits benetzt ist, so daß hierfür kein weiteres Wasser einzubringen ist und infolgedessen der diesem Spülgang entsprechende Wasserverbrauch gesenkt werden kann. Damit wird mit der erfindungsgemäßen Trommelwaschmaschine ein höchst selektives, weil den tatsächlichen Gegebenheiten angepaßtes Spülen ermöglicht.The drum washing machine according to the invention thus realizes with particular advantage the possibility of a selective Rinsing. It has turned out to be for saving water while ensuring a good rinsing effect proven to be advantageous when depending on the Loaded laundry quantity or the laundry type and the numerical Number of pending rinse the selection of Washing program takes place, this then the corresponding Parameters regarding the water to be flushed in and for example the flushing time is adjusted accordingly. Because for example, with a large amount of laundry are slightly larger Amounts of fresh water required, but for example the laundry is already wetted after the second rinse cycle is so that no further water can be introduced for this and is consequently the one corresponding to this rinse cycle Water consumption can be reduced. This is with the invention Drum washing machine a highly selective, because rinsing is adapted to the actual conditions.
In weiterer Erfindungsausgestaltung ist vorgesehen, daß zumindest ein erstes Spülprogramm derart ausgebildet ist, daß ein Teil des einzubringenden Frischwassers mittels der Einsprüheinrichtung direkt auf die mit hoher Geschwindigkeit rotierende, an der Trommelwandung haftende Wäsche eingebracht wird, und daß nach Einbringen eines Teils des Frischwassers das restliche Frischwasser nach Reduzierung der Drehzahl auf eine niedrige Waschdrehzahl über die Einspüleinrichtung zur Bildung einer freien Flotte eingebracht wird. Dieses Programm, das zweckmäßigerweise im ersten Spülgang eingesetzt wird, ist insbesondere zur Vermeidung von Anreicherungsproblemen, die bei einem Spülen nur ohne freier Flotte gegeben sind, von Vorteil. Ferner ist vorteilhaft hierdurch eine schnelle Befeuchtung möglich, da infolge der Trommelrotation das auf die Innenseite des sich bildenden Wäscherings aufgebrachte Wasser schnell nach außen unter Mitnahme etwaiger Verunreinigungen.transportiert wird. Vorteilhaft ist ferner, daß infolge der Bildung einer freien Flotte auch ein Weichspüler oder dergleichen eingespült werden kann.In a further embodiment of the invention it is provided that at least a first washing program is designed such that part of the fresh water to be introduced by means of the spray device directly on the at high speed rotating laundry stuck to the drum wall will, and that after introducing part of the Fresh water the remaining fresh water after reduction the speed to a low washing speed via the induction unit introduced to form a free fleet becomes. This program, which is conveniently in the first Rinse cycle is used in particular to avoid of enrichment problems that only occur with a rinse without free fleet are given, an advantage. It is also advantageous this enables rapid humidification, since due to the rotation of the drum on the inside of the water quickly forming to the outside with any contaminants becomes. It is also advantageous that due to the formation of a free liquor also washed in a fabric softener or the like can be.
Zur weiteren Erhöhung der Selektivität kann vorgesehen sein, daß wenigstens ein Spülprogramm ein Spülen mit freier Flotte und wenigstens ein weiteres Spülprogramm ein Spülen ohne freie Flotte vorsieht. Denn beispielsweise im Rahmen des ersten Spülgangs ist es zweckmäßig, wenn mit mehr Wasser, also mit einer freien Flotte gespült wird, da bei diesem Spülgang die höchste auszuspülende Waschmittelkonzentration vorliegt. Die nachfolgenden Spülgänge können dann mit einem Spülprogramm ohne freier Flotte erfolgen, wobei beispielsweise der letzte Spülgang dann wieder im Hinblick auf ein Klarspülen mit freier Flotte durchgeführt werden kann. To further increase the selectivity can be provided be that at least one wash program is a wash with free Brisk and at least one additional wash program without a free fleet. Because, for example, in the frame the first rinse it is advisable to use more water, So it is rinsed with a free liquor, because with this Rinse cycle the highest detergent concentration to be rinsed out is present. The subsequent rinses can then with a washing program without a free liquor, whereby for example, the last rinse is again in view be carried out on a rinse aid with free liquor can.
In weiterer Erfindungsausgestaltung kann vorgesehen sein, daß zumindest ein zweites Spülprogramm derart ausgebildet ist, daß zumindest ein Teil des einzubringenden Frischwassers mittels der Einsprüheinrichtung direkt auf die mit niedriger Waschdrehzahl rotierende Wäsche eingebracht wird, so daß hierdurch ein Verfahren ohne freie Flotte realisiert ist.In a further embodiment of the invention, that at least a second washing program is designed in this way is that at least part of the fresh water to be introduced by means of the spray device directly onto the low washing speed rotating laundry is introduced, so that this realizes a process without a free fleet is.
Als weitere zweckmäßige Erfindungsausgestaltung hat es sich erwiesen, wenn die Anzahl der Spülgänge abhängig von der Wäschemenge und/oder -art wählbar ist, denn bei nur geringer Beladung ist vor allem dann, wenn bereits der erste Spülgang unter Verwendung einer freien Flotte erfolgt, lediglich ein weiterer Spülgang erforderlich, um eine hinreichende Durchspülung zu gewährleisten. Bei großen Wäschemengen wird dann mit besonderem Vorteil eine entsprechend höhere Anzahl an Spülgängen gewählt.It has proven to be a further expedient embodiment of the invention proven if the number of rinse cycles depends on the Amount and / or type of laundry can be selected, because only a small amount Loading is especially when the first Rinse cycle is done using a free liquor, only Another rinse is required to achieve an adequate To ensure flushing. With large amounts of laundry will then, with particular advantage, be a correspondingly higher one Number of rinses selected.
Um neben der optimierten, den tatsächlichen Gegebenheiten angepaßten Auswahl des spülgangspezifisch anzuwendenden Spülprogramms auch eine den tatsächlichen Gegebenheiten gerechtwerdende Frischwassermenge zuführen zu können, kann im Rahmen der Erfindung ferner vorgesehen sein, daß die Menge an zuzuführendem Frischwasser in Abhängigkeit der Wäschemenge und/oder -art zumindest zu Beginn des Spülbetriebs, vorzugsweise für jeden Spülgang vorbestimmbar ist, um so möglichst wenig Wasser bei Gewährleistung einer ausreichenden Spülung einzusetzen. Da bei dem vorgeschlagenen ersten Spülprogramm eine Aufteilung des einzubringenden Frischwassers, dergestalt vorgesehen ist, daß ein erster Teil mittels der Einsprüheinrichtung, und der Rest mittels der Einspüleinrichtung eingebracht werden kann, kann erfindungsgemäß ferner vorgesehen sein, daß zumindest im Rahmen des ersten Spülprogramms die Menge an mittels der Einsprüheinrichtung einbringbaren Frischwassers vorbestimmbar ist.In addition to the optimized, the actual circumstances adapted selection of the specific rinse cycle to be used Rinsing program also takes into account the actual circumstances Being able to supply fresh water can in Within the scope of the invention it is further provided that the amount of fresh water to be supplied depending on the amount of laundry and / or type, at least at the beginning of the flushing operation, is preferably predeterminable for each wash cycle, so as little water as possible while ensuring sufficient Use flushing. As with the proposed first Rinsing program a division of the fresh water to be introduced, is provided such that a first part by means of the injection device, and the rest by means of the injection device can be introduced can according to the invention further be provided that at least in the context of the first Washing program the amount of by means of the spray device introducible fresh water can be predetermined.
Als besonders zweckmäßig hat es sich ferner erwiesen, wenn die Programmsteuerung zum Auswählen des jeweiligen Sprühprogramms und zum Bestimmen der Frischwassermengen ausgebildet ist.It has also proven to be particularly useful if the program control for selecting the respective spray program and designed to determine the amount of fresh water is.
Neben der erfindungsgemäßen Trommelwaschmaschine betrifft die Erfindung ferner ein Verfahren zum Betrieb einer Trommelwaschmaschine während des Spülbetriebs, welcher aus wenigstens zwei separaten Spülgängen besteht, wobei die Trommelwaschmaschine eine den Spülbetrieb steuernde Programmsteuerung, eine in einem Laugenbehälter drehbar angeordnete Wäschetrommel, wenigstens eine Einspüleinrichtung für gegebenenfalls ein Behandlungsmittel führendes Frischwasser in den Trommelbereich, wenigstens eine Einsprüheinrichtung zum Einsprühen von Frischwasser in das Trommelinnere, und ein den Frischwasserzulauf gegebenenfalls wasserstandsabhängig steuerndes Mittel aufweist.In addition to the drum washing machine according to the invention relates the invention further a method for operating a drum washing machine during the flushing operation, which consists of at least there are two separate rinses, the drum washing machine a program control that controls the flushing operation, one rotatably arranged in a tub Laundry drum, at least one washing device for, if necessary a treatment agent carrying fresh water in the drum area, at least one injection device for Spraying fresh water into the inside of the drum, and a the fresh water supply may depend on the water level controlling agent.
Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß im Rahmen des ersten Spülgangs die Wäschetrommel mit einer einem Schleuderbetrieb entsprechenden Drehzahl rotiert, wonach über die Einsprüheinrichtung ein vorbestimmter Teil am Frischwasser in das Trommelinnere gesprüht, anschließend die Drehzahl auf eine Waschdrehzahl erniedrigt und das restliche Frischwasser über die Einsprüheinrichtung oder die Einspüleinrichtung zur Bildung einer freien Flotte zugegeben wird, und daß der nachfolgende Spülgang entweder in gleicher Weise erfolgt, oder über die Einsprüheinrichtung eine vorbestimmte Wassermenge ohne Bildung einer freien Flotte eingebracht wird, wobei nach jedem Spülgang freies Wasser abgepumpt wird.The method according to the invention is characterized in that that as part of the first rinse with the laundry drum rotates at a speed corresponding to a spin operation, after which a predetermined Part of the fresh water sprayed into the inside of the drum, then the speed is reduced to a washing speed and the remaining fresh water via the injection device or the flushing device to form a free liquor is added, and that the subsequent rinse either done in the same way, or via the injection device a predetermined amount of water without forming a free one Brisk is introduced, with free after each rinse Water is pumped out.
Bei dem erfindungsgemäßen Verfahren erfolgt also vorteilhaft im Rahmen des ersten Spülgangs unabhängig von der Art der Beladung stets ein Spülen mit freier Flotte, wobei sich die bereits genannten, aus der Schleuderbenetzung ergebenden Vorteile erzielen lassen. Erst bei den nachfolgenden Spülgängen besteht die Wahlmöglichkeit hinsichtlich eines Spülens mit oder ohne freier Flotte, wobei das bei diesen Spülgängen verwendete Spülverfahren (freie Flotte - ohne freie Flotte) erfindungsgemäß in Abhängigkeit der beladenen Wäschemenge und/oder -art und/oder der numerischen Anzahl des Spülgangs gewählt wird.The method according to the invention is therefore advantageous as part of the first wash cycle regardless of the type the load always a rinse with free liquor, whereby those already mentioned, resulting from spin wetting Allow advantages. Only with the following Rinse cycles have the option of one Rinsing with or without a free fleet, this being the case with these Rinsing processes used (free fleet - without free fleet) according to the invention depending on the loaded Amount and / or type of laundry and / or the numerical number the wash cycle is selected.
Erfindungsgemäß kann die Spülzeit nach Beendigung der Einbringung des restlichen Wassers im Rahmen des Spülens mit freier Flotte weniger als 5 Minuten, vorzugsweise weniger als 4 Minuten betragen. Die Einwirkzeit nach Beendigung der Einbringung von Frischwasser bei dem Spülgang ohne freie Flotte kann erfindungsgemäß ca. 2 Minuten, vorzugsweise ca. 1 Minute betragen.According to the rinse time after the end of the introduction the remaining water as part of the rinsing free liquor less than 5 minutes, preferably less be more than 4 minutes. The exposure time after the end of Introducing fresh water in the rinse cycle without free The liquor can, according to the invention, be about 2 minutes, preferably about 1 minute.
Um beim letzten Spülgang die Sicherheit zu haben, daß tatsächlich sämtliches auszuspülendes Mittel entfernt wird, kann im Rahmen der Erfindung ferner vorgesehen sein, daß beim letzten Spülgang das Spülverfahren mit freier Flotte verwendet wird.In order to have the certainty of the last rinse that it actually does all rinsing agent is removed, can also be provided within the scope of the invention that in the last rinse, the rinsing process with free liquor is used.
