Abstract

The method involves evacuating industrial water over a sewage system in a housing of a washing machine (1). An outlet pump (9) i.e. rotation speed-controllable pump, is driven with respect to rotation speed based on flow of intended fresh water for steam generation and predetermined water level (H0) is reached by which portion of the water in a caustic solution container (3) is carried into voids of the sewage system. A water level sensor (5) is connected with a control device (13) to set predetermined water level (H1) for the steam generation through a heating element (6).

Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Waschmaschine, insbesondere einer Trommelwaschmaschine, umfassend eine Wäschetrommel zur Aufnahme der zu waschenden Wäsche, eine Zuführvorrichtung für das in den Laugenbehälter einzuleitende Frischwasser, ein im Laugenbehälter angeordneter Heizkörper für das Aufheizen des Waschwassers, der ebenfalls als Heizvorrichtung zur Dampferzeugung für das Behandeln der Wäsche mit Dampf dient, eine Ablaufpumpe für das Abpumpen des Brauchwassers über das im Gehäuse der Waschmaschine angeordnete Abwassersystem, eine Steuerungsvorrichtung, durch die in Verbindung mit einem Wasserstandssensor die programmgemäß vorgesehenen Wasserstände in der Maschine eingestellt werden.The invention relates to a method for operating a washing machine, in particular a drum washing machine, comprising a laundry drum for receiving the laundry to be washed, a feeding device for the fresh water to be introduced into the tub, a heating body arranged in the tub for heating the wash water, which also serves as a heating device for Steam generation for treating the laundry with steam is used, a drain pump for pumping out the process water through the arranged in the housing of the washing machine sewer system, a control device, are set in accordance with the program according to water levels in the machine in conjunction with a water level sensor.

Bei Waschmaschinen ist es allgemein bekannt, zur Verbesserung der erzielbaren Behandlungsergebnisse, die zu behandelnde Wäsche mit Dampf zu beaufschlagen. Durch den Einsatz von Dampf soll die Knitterbildung in der Wäsche verhindert werden oder es sollen am Ende des Programms eventuell vorhandene Knitter aus der Wäsche entfernt werden.In washing machines, it is generally known, in order to improve the achievable treatment results, to apply the laundry to be treated with steam. The use of steam is intended to prevent creasing in the laundry or to remove any creases from the laundry at the end of the program.

Aus EP 2 381 029 A1 ist es beispielsweise bekannt, bei einer Waschmaschine die für das Aufheizen des Waschwassers vorhandene Heizvorrichtung auch zur Erzeugung von Dampf zu nutzen. Der Heizkörper der Maschine wird dabei knapp überflutet und das Wasser um den Heizkörper so stark erhitzt, dass Dampf entstehen kann. Durch den natürlichen Auftrieb kann dieser Dampf dann in die Wäschetrommel und in Kontakt mit der Wäsche gelangen.Out EP 2 381 029 A1 For example, it is known to use the existing for heating the washing water heater for generating steam in a washing machine. The radiator of the machine is just flooded and the water around the radiator heated so much that steam can occur. Due to the natural buoyancy of this steam can then get into the laundry drum and in contact with the laundry.

Bei einem Dampferzeugungssystem in der vorgenannten Art bereitet es Schwierigkeiten, die Wasserstandshöhe so einzuregeln, dass es zu einer optimalen Dampfentwicklung kommen kann. Befindet sich der im Laugenbehälter angeordnete Heizkörper zu tief im Wasser, so kann kein Dampf mit ausreichender Intensität erzeugt werden. Er darf aber während des Einschaltbetriebes auch nicht längere Zeit aus dem Wasser herausragen, da dann die Gefahr einer Überhitzung gegeben sein kann.In a steam generating system in the aforementioned type, it is difficult to regulate the water level so that it can come to an optimal vapor development. If the radiator located in the tub is too deep in the water, steam of sufficient intensity can not be generated. However, during the switch-on mode, it must not protrude out of the water for a longer period of time, because then the danger of overheating may exist.

Hier den genau passenden Wasserstand für den Dampferzeugungsprozess einregeln zu können, gestaltet sich insofern schwierig, da der Wassereinlauf sehr dynamisch abläuft und das Wassereinlaufsystem einem gewissen Trägheitsmoment unterliegt. Nach dem Abschalten des Einlaufventils durch den Wasserstandssensor kann eine nicht immer genau bestimmbare Wassermenge in den Laugenbehälter nachlaufen.Here, to be able to adjust the exact water level for the steam generation process, so far difficult, since the water inlet is very dynamic and the water inlet system is subject to a certain moment of inertia. After switching off the inlet valve by the water level sensor, a not always determinable amount of water can run into the tub.

Der Erfindung stellt sich somit das Problem, für eine Waschmaschine ein Verfahren bereitzustellen, mit dem Dampf durch den im Laugenbehälter angeordneten Heizkörper in ausreichender Menge und hoher Intensität erzeugt werden kann.The invention thus raises the problem of providing for a washing machine, a method by which steam can be generated by the arranged in the tub radiator in a sufficient amount and high intensity.

Erfindungsgemäß wird dieses Problem durch ein Verfahren mit den Merkmalen desAccording to the invention, this problem is solved by a method having the features of

Patentanspruchs 1 oder mit den Merkmalen des unabhängigen (nebengeordneten)Patent claim 1 or with the characteristics of the independent (sibling)

Patentanspruchs 2 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Patent claim 2 solved. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die im Patentanspruch 1 und 2 vorgeschlagenen Ausführungsformen unterscheiden sich dadurch, dass der eingeschaltete Heizkörper während der Dampferzeugung einmal vom Wasser umgeben ist, während er bei der zweiten Ausführungsform lediglich mit Wasser benetzt ist. Beide Varianten basieren aber auf dem gemeinsamen Gedanken, eine drehzahlregelbare Ablaufpumpe zu verwenden, mit der es durch eine gezielte Steuerung der Drehzahl möglich wird, eine Teilmenge des im Laugenbehälter vorhandenen Wassers in des Abwassersystem zu verlagern, ohne das dieses Wasser nach außen abgepumpt wird. Dadurch können im Laugenbehälter definierte Wasserstände für den Verdampfungsprozess eingeregelt werden.The proposed in claim 1 and 2 embodiments differ in that the activated radiator is once surrounded by the water during steam generation, while it is wetted in the second embodiment only with water. However, both variants are based on the common idea to use a variable speed drain pump, with which it is possible by targeted control of the speed to shift a subset of existing in the tub water in the sewer system, without this water is pumped to the outside. As a result, defined water levels for the evaporation process can be adjusted in the tub.

Die im Patentanspruch 1 angegebene Erfindung beruht auf der Ausgangsüberlegung, die Regelung des für die Dampferzeugung vorteilhaften Wasserstandes erst dann einzuleiten, nachdem der anfängliche Tankvorgang abgeschlossen ist. Dadurch lassen sich Messungenauigkeiten vermeiden, die durch eventuell nachlaufendes Wasser oder durch im Laugenbehälter noch nicht zur Ruhe gekommene Wasserbewegungen hervorgerufen werden.The specified in claim 1 invention is based on the initial idea to initiate the regulation of the advantageous for steam generation water level only after the initial refueling is completed. As a result, measurement inaccuracies can be avoided, which are caused by any trailing water or by water movements that have not yet settled in the tub.

Die mit der Erfindung erreichbaren Vorteile bestehen somit insbesondere darin, dass das Einregeln eines für den Verdampfungsprozess definierten Wasserstandes durch ohnehin vorhandene Bauelemente und Steuerungsvorrichtungen ermöglicht wird und damit eine effiziente Dampferzeugung durch den im Laugenbehälter vorhandenen Heizkörper erzielt werden kann. Somit kann eine prozessoptimierte Dampferzeugung in der Waschmaschine realisiert werden.The advantages achievable with the invention thus consist in particular in the fact that the adjustment of a water level defined for the evaporation process is made possible by already existing components and control devices and thus an efficient steam generation can be achieved by the radiator present in the tub. Thus, a process-optimized steam generation can be realized in the washing machine.

In der Figur 1 ist eine Waschmaschine 1 mit den zur Erläuterung der Erfindung notwendigen Bauteilen dargestellt. Der Zulauf des Frischwassers erfolgt wie üblich über die Einlassventile 2 und den Waschmitteleinspülkasten 21 in den Laugenbehälter 3, in dem die Wäschetrommel 4 drehbar gelagert ist. Das innerhalb des Waschmaschinengehäuses angeordnete Abwassersystem wird hier von der als Faltenbalg ausgebildeten Ablaufleitung 7, dem Filtergehäuse 8, der Ablaufpumpe 9, der Verbindungsleitung 10 sowie der Rücklaufsicherung 11 gebildet. Über den außen an der Waschmaschine 1 angeschlossenen Ablaufschlauch 12 kann das Abwasser in die Kanalisation befördert werden.In the FIG. 1 is a washing machine 1 shown with the necessary components for explaining the invention. The feed of the fresh water is carried out as usual via the inlet valves 2 and the Waschmitteleinspülkasten 21 in the tub 3, in which the laundry drum 4 is rotatably mounted. The arranged within the washing machine housing Sewage system is here formed by the bellows designed as a drain line 7, the filter housing 8, the drain pump 9, the connecting line 10 and the return valve 11. About the outside connected to the washing machine 1 drain hose 12, the wastewater can be transported to the sewer.

Im unteren Bereich des Laugenbehälters 3 ist der Heizkörper 6 der Heizvorrichtung angeordnet, mit dem sowohl das Waschwasser als auch das für die Dampferzeugung vorgesehene Frischwasser aufgeheizt werden kann.In the lower part of the tub 3, the heating element 6 of the heating device is arranged, with which both the washing water and the steam provided for generating fresh water can be heated.

Der symbolisch dargestellte Wasserstandssensor 5 sorgt in Verbindung mit der angeordneten Steuervorrichtung 13 dafür, dass die für das jeweilige Programm benötigten Wasserstände im Laugenbehälter 3 eingestellt werden können.The symbolically represented water level sensor 5, in conjunction with the arranged control device 13, ensures that the water levels required for the respective program can be set in the tub 3.

Nachfolgend wird zunächst die erste Ausführungsform des erfindungsgemäßen Verfahrens für die Dampferzeugung durch den Heizkörper 6 beschrieben.Hereinafter, first, the first embodiment of the method according to the invention for the generation of steam by the radiator 6 will be described.

Einen wesentlichen Bestandteil bildet dabei die Ablaufpumpe 9, die als drehzahlregelbare Pumpe ausgebildet sein muss. Zuerst wird das für die Dampferzeugung vorgesehene Frischwasser in den Laugenbehälter 3 geleitet, bis z.B. ein vorbestimmter Wasserstand Ho erreicht ist, der oberhalb der Oberkante des Heizkörpers 6 liegt.An essential part of this is the drain pump 9, which must be designed as variable speed pump. First, the fresh water intended for steam generation is led into the tub 3, until e.g. a predetermined water level Ho is reached, which is above the upper edge of the radiator 6.

Wenn sich dieser Wasserstand nach dem Einlaufvorgang eingepegelt hat, wird die Drehzahl der Ablaufpumpe 9 langsam bis auf eine Drehzahlstufe erhöht bzw. mit einer gegenüber der Abpumpdrehzahl niedrigeren Drehzahl angetrieben. Diese Drehzahlstufe wird dabei so bemessen, dass ein Teil des im Laugenbehälter 3 befindlichen Wassers in die vorhandenen Leerräume des Abwassersystems befördert werden kann, ohne dass aber ein Abpumpen nach außen erfolgt. Als Leerraum im Abwassersystem kommt z.B. die übliche Rücklaufsicherung 11 in Frage, die nach dem Abschalten der Ablaufpumpe 9 zum Teil nicht vollständig gefüllt ist.If this level has leveled after the inlet process, the speed of the drain pump 9 is slowly increased to a speed level or driven at a lower speed compared to the Abpumpdrehzahl. This speed level is thereby dimensioned so that a portion of the water in the tub 3 can be conveyed into the existing voids of the sewer system, but without an outward pumping. As a white space in the sewage system is e.g. the usual return valve 11 in question, which is not completely filled after switching off the drain pump 9 in part.

Durch die vorbeschriebene Maßnahme kann der Wasserstand im Laugenbehälter 3 durch den Wasserstandssensor 5 in Verbindung mit der Steuervorrichtung 13 auf einen neuen Wasserstand H1 soweit abgesenkt werden, dass der Heizkörper 6 nur noch soeben mit Wasser bedeckt ist. Wenn nun der Heizkörper 6 programmgemäß eingeschaltet wird, kann sich durch diese nur noch geringfügig oberhalb des Heizkörpers 6 vorhandene Wasserschicht eine intensive Dampfentwicklung ergeben. Der aufsteigende Dampf gelangt dann durch den natürlichen Auftrieb in die in der Wäschetrommel 4 befindliche Wäsche.By the measure described above, the water level in the tub 3 can be lowered so far by the water level sensor 5 in conjunction with the control device 13 to a new water level H1 that the radiator 6 is just covered with water. Now, if the radiator 6 is switched on according to the program, this can only be found slightly above the radiator 6 existing water layer an intense vapor evolution. The rising steam then passes through the natural buoyancy in the laundry located in the laundry drum 4.

Um Dampf in ausreichender Menge und mit geeigneter Intensität zu erzeugen, sind die Heizleistung des Heizkörpers und der Wasserstand H1 während des Heizbetriebes entsprechend aufeinander abzustimmen. Die Steuerung des Systems kann so eingerichtet werden, dass der Ausgleich für das verdampfte Wasser über die einzustellende Drehzahl an der Ablaufpumpe erfolgt, wodurch mehr oder weniger Wasser in den Leerraum des Abwassersystems verlagert wird. Weiterhin kann die evtl. fehlende Wassermenge auch über einen Nachtankvorgang ausgeglichen werden.In order to generate steam in sufficient quantity and with suitable intensity, the heating power of the radiator and the water level H1 during heating operation are matched accordingly. The control of the system can be set up so that the compensation for the evaporated water over the set speed the drain pump takes place, whereby more or less water is displaced into the empty space of the sewage system. Furthermore, the possibly missing amount of water can also be compensated by a Nachankvorgang.

Durch die vorhandene Sensorik in der Waschmaschine - Drehzahlregelung der Pumpe, das Einstellen der Drehzahl auf ein bestimmtes Drehzahl-Plateau, die Wasserstandsregelung durch den Druckwächter - kann somit eine für den Dampferzeugungsprozess optimale Wasserstandshöhe eingeregelt werden, was zu einer schnellen Dampferzeugung führt.By the existing sensors in the washing machine - speed control of the pump, setting the speed to a certain speed plateau, the level control by the pressure switch - can thus be adjusted for the steam generation process optimum water level, resulting in rapid steam generation.

Eine zweite erfindungsgemäße Ausführungsform wird im Folgenden zusätzlich mit Figur 3 erläutert.A second embodiment according to the invention is additionally described below FIG. 3 explained.

Einen wesentlichen Bestandteil bildet auch hier die drehzahlregelbare Ablaufpumpe 9, durch die mit einer niedrig einstellbaren Drehzahl eine gewisse Wassermenge aus dem Laugenbehälter 3 in das Abwassersystem verlagert werden kann. In diesem Fall wird jedoch ein Wasserstand H2 angesteuert, bei dem sich der Heizkörper 6 nicht mehr oder zumindest nur noch teilweise im Wasser befindet. Wenn die Ablaufpumpe 9 nun intermittierend betrieben wird, wie dies in den Figuren 3 und 4 sinnbildlich dargestellt ist, kann man einen Wechsel zwischen einem freiliegenden und einen mit Wasser bedeckten Heizkörper 6 erzeugen. Dieser Wechsel kann so abgestimmt werden, dass das den freiliegenden Heizkörper 6 noch benetzende Restwasser schnell verdampft und ein Überhitzen des Heizkörpers 6 durch das den Heizkörper 6 anschließend umflutende Wasser vermieden wird.An essential part here too is the variable-speed drainage pump 9, through which a certain amount of water can be displaced from the tub 3 into the sewage system at a low adjustable speed. In this case, however, a water level H2 is controlled, in which the radiator 6 is no longer or at least only partially in the water. When the drain pump 9 is now operated intermittently, as shown in the Figures 3 and Fig. 4 is symbolically illustrated, one can create a change between an exposed and a water-covered radiator 6. This change can be adjusted so that the exposed radiator 6 still wetting residual water evaporates quickly and overheating of the radiator 6 is avoided by the radiator 6 then flooding water.

Der intermittierende Betrieb der Ablaufpumpe 9 lässt sich durch das wechselnde Ein- und Ausschalten oder durch Betreiben der Ablaufpumpe 9 mit unterschiedlichen Drehzahlstufen realisieren, um den kurzzeitigen Wechsel der Wasserstände H1 und H2 herbeizuführen.The intermittent operation of the drain pump 9 can be realized by the alternating switching on and off or by operating the drain pump 9 with different speed levels to bring about the short-term change of water levels H1 and H2.

Mit dieser Variante lässt sich eine wirksame Impulsbedampfung erzeugen, durch die für verschiedene Situationen gute Behandlungsergebnisse für die Wäsche erzielt werden können. Wie das Diagramm in der Figur 3 verdeutlicht, bestimmen die Parameter Wasserstand H1 und H2 sowie die durch das Ein- und Ausschalten der Ablaufpumpe 9 sich ergebende Impulsbreite tA den Dampferzeugungsvorgang. Dabei sind die Parameter so einzustellen, dass sich quasi eine oszillierende Bewegung des Wasserstandes ergibt, wobei im ständigen Wechsel eine Stoßverdampfungsphase und eine Abkühlungsphase für den Heizkörper erhalten wird.With this variant, an effective impulse vaporization can be produced, by which good treatment results for the laundry can be achieved for different situations. Like the diagram in the FIG. 3 clarifies the parameters determine water level H1 and H2 as well as the resulting by turning on and off the drain pump 9 pulse width t A the steam generating process. In this case, the parameters are to be adjusted so that there is an oscillating movement of the water level as it were, with a continuous vaporization phase and a cooling phase for the heating element being obtained.

Die zur Durchführung der vorbeschriebenen Verfahren anzusteuernden Drehzahlstufen sind je nach den konkreten Gegebenheiten in der Waschmaschine empirisch zu ermitteln. Die jeweilige Drehzahl wird dabei unterhalb der Drehzahl liegen, die für den Abpumpvorgang des Abwassers eingestellt ist. Wesentlich ist es dabei, dass durch die angesteuerte Drehzahlstufe eine bestimmte Teilmenge des Wassers in vorhandene Leerräume des Ablaufsystems befördert werden kann, ohne dass das Wasser nach außen abgeführt wird. Wenn eine gewisse Wassermenge verdampft ist, kann dies natürlich auch hier durch einen entsprechenden Nachtankvorgang ausgeglichen werden.The speed stages to be controlled for carrying out the above-described methods are to be determined empirically depending on the specific conditions in the washing machine. The respective speed will be below the speed, which is set for the Abpumpvorgang the wastewater. It is essential that a specific subset of the water can be transported into existing voids of the drain system by the controlled speed level, without the water is discharged to the outside. If a certain Volume of water has evaporated, this can of course be compensated here by a corresponding Nachtankvorgang.

Weiterhin sieht eine zweckmäßige Ausgestaltung für beide Varianten des erfindungsgemäßen Verfahrens vor, die Ablaufpumpe 9 in der Art einer Sanftanlauffunktion langsam auf das vorgesehene Drehzahl-Plateau hoch laufen zu lassen, damit nicht schon durch den Einschaltimpuls Wasser aus dem Abwassersystem der Maschine herausschwappen kann.Furthermore, an expedient embodiment provides for both variants of the method according to the invention, the drain pump 9 to run slowly in the manner of a soft start function on the intended speed plateau, so that can not spill out by the switch-on water from the sewer system of the machine.
