Description

Die Erfindung betrifft eine Trommelwaschmaschine gemäß Oberbegriff des Anspruchs 1.The invention relates to a drum washing machine according to the preamble of claim 1.

Bei Waschmaschinen der im Oberbegriff genannten Art besteht ein besonderes Problemfeld darin, die während des bei hohen Drehzahlen durchgeführten Schleuderprogramms zwangsläufig auftretenden Unwuchten zu beherrschen.In washing machines of the type mentioned in the preamble, a particular problem area is to control the imbalances inevitably occurring during the centrifugal program carried out at high speeds.

In der Praxis sind die Waschmaschinen mit einer Steuerung ausgestattet, die Unwuchten erkennt und über die Beeinflussung der Drehzahl des Antriebsmotors den Hochlauf der Wäschetrommel steuert. Mit diesem seit langem eingesetzten Steuerungsverfahren soll eine bessere Verteilung der Wäsche erreicht werden. Da dieser Prozess aber nicht immer erfolgreich durchgeführt werden kann, wird dann häufig der Schleudervorgang nicht mit einer optimalen Drehzahl beendet.In practice, the washing machines are equipped with a control that detects imbalances and controls the acceleration of the laundry drum by influencing the speed of the drive motor. With this long-established control method, a better distribution of the laundry should be achieved. However, since this process can not always be carried out successfully, then often the spinning process is not terminated with an optimal speed.

Es sind weiterhin Lösungen für Unwuchtausgleichssysteme bekannt geworden, bei denen die Wäschetrommel mit Ausgleichsbehältern ausgerüstet wird, in die Flüssigkeit in einem geregelten Prozess eingeleitet werden kann, um den auftretenden Unwuchten entgegen zu wirken. Eine derartige Ausführungsform ist beispielsweise aus der DE 10 2009 044 709 bekannt.There are also known solutions for balancing systems, in which the laundry drum is equipped with expansion tanks, can be introduced into the liquid in a controlled process to counteract the occurring imbalances. Such an embodiment is for example from the DE 10 2009 044 709 known.

Weiterhin werden im praktischen Einsatz bei Waschmaschinen so genannte Umflutungssysteme verwendet, um eine bessere und schnellere Durchfeuchtung des Wäschepostens zu erreichen ( DE 10 2008 046 465 A1 ). Außerdem lässt sich mit einer Umflutungseinrichtung insgesamt die Waschwirkung verbessern und der Wasserverbrauch reduzieren.Furthermore, so-called flooding systems are used in practical use in washing machines in order to achieve a better and faster moisture penetration of the laundry item ( DE 10 2008 046 465 A1 ). In addition, with a flooding device overall, the washing effect can be improved and water consumption reduced.

Der Nachteil dieser beiden bei Waschmaschinen seit langem bekannten Arbeitsverfahren besteht darin, dass jeweils für die einzelnen getrennt arbeitenden Systeme eigene Bauteilkomponenten eingesetzt werden müssen, was den aparativen Aufwand nicht unerheblich erhöht. Beide Systeme erfordern unter anderem Pumpen, Verbindungsleitungen für die Wasserführung sowie Ventile, Düsen, Filter und spezielle Steuereinrichtungen.The disadvantage of these two long-known in washing machines working method is that in each case for the individual separately operating systems own component components must be used, which increases the aparativen expenditure not insignificant. Both systems require, among other things, pumps, connecting lines for the water supply and valves, nozzles, filters and special control devices.

Weiterhin erfordert das Ausgleichssystem mit Ausgleichsbehältern an der Trommel einen zusätzlichen Wasserverbrauch, der nicht am Wasch- und Spülprozess teilnimmt.Furthermore, the compensation system with expansion tanks on the drum requires additional water consumption, which does not participate in the washing and rinsing process.

In der DE 10 2011 054 446 A1 wird zwar bereits eine Waschmaschine beschrieben, die sowohl ein Unwuchtausgleichssystem mit Ausgleichsbehältern als auch eine Umflutungseinrichtung besitzt, jedoch wird darin in erster Linie die Neugestaltung der an der Trommel angebrachten Ausgleichsbehälter detailliert behandelt, die Umflutungseinrichtung wird lediglich nur beiläufig angedeutet. Im übrigen weist die hier beschriebene Ausführungsform die gleichen Nachteile auf, die zuvor genannt wurden.In the DE 10 2011 054 446 A1 Although a washing machine is already described, which has both an imbalance compensation system with surge tanks and a flooding device, but it is primarily the redesign of the mounted on the drum Reservoir treated in detail, the Umflutungseinrichtung is only hinted at casually. Otherwise, the embodiment described here has the same disadvantages as mentioned above.

Der Erfindung stellt sich somit das Problem, bei einer Waschmaschine der eingangs genannten Art die vorstehend genannten Nachteile zu vermeiden und eine Waschmaschine bereit zu stellen, bei der ein Unwuchtausgleichssystem sowie ein Umflutungssystem mit einem verringertem Aufwand und reduzierten Kosten gleichzeitig betrieben werden kann.The invention thus raises the problem of avoiding the aforementioned disadvantages in a washing machine of the type mentioned above and to provide a washing machine, in which an imbalance compensation system and a Umflutungssystem can be operated simultaneously with a reduced effort and reduced costs.

Erfindungsgemäß wird dieses Problem durch eine Trommelwaschmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a drum washing machine having the features of patent claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen insbesondere darin, dass eine Kostenreduzierung durch den Wegfall von Bauteilen ermöglicht wird. Weiterhin kann eine Verringerung des Wasserverbrauchs erzielt werden.The achievable with the present invention consist in particular that a cost reduction is made possible by the elimination of components. Furthermore, a reduction in water consumption can be achieved.

Ferner ist es vorstellbar, dass neue Programme und Verfahrenstechniken sowie Synergieeffekte durch die Kombination der beiden unterschiedlichen Systeme realisiert werden können.It is also conceivable that new programs and techniques as well as synergy effects can be realized by combining the two different systems.

Ein Ausführungsbeispiel der Erfindung ist in der einzigen Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigt

Figur 1
die Prinzipskizze einer Trommelwaschmaschine mit den zur Erläuterung der Erfindung notwendigen Bauteile.
An embodiment of the invention is shown purely schematically in the single drawings and will be described in more detail below. It shows
FIG. 1
the schematic diagram of a drum washing machine with the necessary components for explaining the invention.

Die in der Zeichnung ihrer Gesamtheit nicht dargestellte Trommelwachmaschine zeigt den Laugenbehälter 1 mit der darin drehbar gelagerten Wäschetrommel 2. Über den hier nicht gezeichneten Antriebsmotor wird die Wäschetrommel 2 während des Wasch- und Schleuderganges angetrieben.The drum winder, not shown in the drawing of its entirety, shows the tub 1 with the laundry drum 2 rotatably mounted therein. The laundry drum 2 is driven during the wash and spin cycle via the drive motor not shown here.

Im unteren Bereich des Laugenbehälters 1 weist die Waschmaschine in diesem Ausführungsbeispiel ein steuerbares Ablaufventil 3 auf, durch das die Behandlungsflüssigkeit über die Ablaufleitung 19 in das Abwassernetz abgelassen werden kann. Wenn das Ablaufventil 3 in die in der Zeichnung dargestellten Position geschaltet wird, kann das Umflutungssystem aktiviert werden. Während des Umflutvorganges wird die Flüssigkeit aus dem Laugenbehälter 1 durch die Umflutpumpe 4 und die im Bereich der Beschickungsöffnung 6 angeordnete Einspritzdüse 5 in das innere der Wäschetrommel 2 eingeleitet, um hier eine schnelle Durchfeuchtung und intensive Durchdringung der Wäsche mit der Waschlauge zu erreichen.In the lower region of the tub 1, the washing machine in this embodiment, a controllable drain valve 3, through which the treatment liquid can be discharged via the drain line 19 into the sewer network. When the drain valve 3 is switched to the position shown in the drawing, the flooding system can be activated. During the Umflutvorganges the liquid from the tub 1 through the circulating pump 4 and arranged in the region of the feed opening 6 injector 5 is introduced into the interior of the laundry drum 2 to achieve a rapid moisture penetration and intensive penetration of the laundry with the wash liquor.

Die hier gezeigte Trommelwaschmaschine ist weiterhin mit einem Unwuchtausgleichssystem ausgestattet, wobei an der vorderen und der hinteren Stirnseite der Wäschetrommel 2 jeweilsThe drum washing machine shown here is further equipped with an imbalance compensation system, wherein at the front and the rear end face of the laundry drum 2 respectively

Ausgleichsbehälter 11 und 12 angeordnet sind, die Flüssigkeit für den Unwuchtausgleich aufnehmen können. Dies erfolgt im Bedarfsfall jeweils über die in der vorderen und in der hinteren Wand des Laugenbehälters 1 angeordneten Einspritzdüsen 9 und 10.Expansion tank 11 and 12 are arranged to receive the liquid for balancing. This is done in each case via the arranged in the front and in the rear wall of the tub 1 injectors 9 and 10, if necessary.

In einer vorteilhaften Weiterbildung sind im vorliegenden Ausführungsbeispiel zwischen dem Laugenbehälter 1 und der Wäschetrommel 2 im Bereich der Einspritzdüsen 9, 10 so genannte Regulierungsscheiben 15, 16 vorgesehen. Diese Regulierungsscheiben 15, 16 werden durch Stellvorrichtungen 13, 14, z. B. in Form eines Stellmotors angetrieben. Die Regulierungsscheiben 15, 16 sind vorzugsweise kreisförmig ausgebildet und weisen auf ihrer Fläche partiell geschlossene und geöffnete Segmente auf.In an advantageous development, in the present exemplary embodiment, so-called regulating discs 15, 16 are provided between the tub 1 and the laundry drum 2 in the region of the injection nozzles 9, 10. These regulation discs 15, 16 are controlled by adjusting devices 13, 14, z. B. driven in the form of a servomotor. The regulation discs 15, 16 are preferably circular in shape and have on their surface partially closed and opened segments.

Je nach Stellposition können sie den Durchlass zu den gegenüberliegenden Einlassöffnungen in den Ausgleichsbehältern 11, 12 blockieren oder freigeben. Die Einspritzdüsen 9, 10 spritzen kontinuierlich Wasser auf die Regulierungsscheiben 15, 16. Im blockierten Zustand leiten die Regulierungsscheiben 15, 16 das Wasser ab und es fließt zum Beispiel wieder in den Laugenbehälter zurück. Im freigegeben Zustand kann das Wasser durch die offenen Segmente der Regulierungsscheiben 15, 16 in die Ausgleichsbehältern 11, 12 gelangen.Depending on the setting position, they can block or release the passage to the opposite inlet openings in the expansion tanks 11, 12. The injection nozzles 9, 10 continuously inject water onto the regulation discs 15, 16. In the blocked state, the regulation discs 15, 16 discharge the water and it flows, for example, back into the tub. In the released state, the water can pass through the open segments of the regulation discs 15, 16 in the surge tanks 11, 12.

Die Lageposition der Regulierungsscheiben 15, 16 wird in Abhängigkeit von der auftretenden Unwucht durch die Steuereinrichtung 21 in Verbindung mit der zentralen, elektronischen Programmsteuereinrichtung 20 sowie durch die Aktivierung des jeweiligen Stellmotors 13 oder 14 eingestellt.The positional position of the regulation discs 15, 16 is set by the control device 21 in conjunction with the central electronic program control device 20 as well as by the activation of the respective servomotor 13 or 14 as a function of the imbalance that occurs.

Je nach Lage der Unwucht wird dann der vordere oder der hintere Ausgleichsbehälter 11, 12 mit mehr oder weniger Flüssigkeit beaufschlagt. Darüber hinaus kann über die Drehgeschwindigkeit der Stellmotoren die relative Lage der offenen Segmente beeinflusst werden, sodass diese im zum Unwuchtausgleich nötigen richtigen Moment den Weg in die Ausgleichsbehälter 11, 12 öffnen.Depending on the position of the imbalance then the front or the rear reservoir 11, 12 is acted upon with more or less liquid. In addition, can be influenced by the rotational speed of the servomotors, the relative position of the open segments, so that they open in the balancing necessary right moment the way into the expansion tank 11, 12.

Nach Beendigung des Schleudervorgangs kann dann das für den Unwuchtausgleich verwendete Wasser abgelassen oder für den nächsten Waschvorgang wieder benutzt werden.After completion of the spin operation, the water used for the balancing can then be drained or used again for the next wash.

Die Funktion der gezeigten Anordnung ist wie folgt:

  • Während des Waschvorgangs kann die Umwälzung der Waschflotte in der üblichen Weise erfolgen, in dem die Umflutpumpe 4 die Behandlungsflüssigkeit im Kreislauf aus dem Laugenbehälter 1, über die Zuleitung 17 und die Einspritzdüse 5 in die Wäschetrommel 2 der Maschine befördert.
The function of the arrangement shown is as follows:
  • During the washing process, the circulation of the wash liquor can take place in the usual manner in which the circulating pump 4 conveys the treatment liquid in circulation from the tub 1, via the supply line 17 and the injection nozzle 5 in the washing drum 2 of the machine.

Während des Schleudervorganges wird dann die Abzweigvorrichtung 7 in die Position umgeschaltet, bei der die Zuleitung 18 zum Unwuchtausgleichsystem mit der von der Umflutpumpe 4 kommenden Zuleitung 17 verbunden wird.During the spin process, the branch device 7 is then switched to the position at which the supply line 18 is connected to the balancing system with the coming of the circulating pump 4 supply line 17.

Wenn sich nun während des Schleudervorgangs eine Unwucht in der Wäschetrommel bildet, wird dies von der Steuereinrichtung 21 erkannt und ausgewertet. Durch die Steuereinrichtung 21 wird dann veranlasst, dass die Regulierungsscheiben 15, 16 derart von dem Stellmotor 13 oder 14 betätigt werden, dass das geöffnete Segment in der Regulierungsscheibe mit der Einlassöffnung des der Unwucht gegenüberliegenden Ausgleichsbehälters 11 oder 12 in Deckung steht. Somit kann sich dann der jeweilige Ausgleichsbehälter 11 oder 12 mit Wasser füllen und die Unwucht ausgleichen.If an imbalance forms in the laundry drum during the spinning process, this is detected and evaluated by the control device 21. The control device 21 then causes the regulation disks 15, 16 to be actuated by the servomotor 13 or 14 such that the opened segment in the regulation disk coincides with the inlet opening of the equalization tank 11 or 12 located opposite the unbalance. Thus, then the respective expansion tank 11 or 12 fill with water and compensate for the imbalance.

Durch eine Rotationsbewegung der Regulierscheibe kann der Auswuchtvorgang beschleunigt werden.By a rotational movement of the regulating wheel of the balancing process can be accelerated.

Auf der anderen Seite steht die Regulierungsscheibe dem geschlossenen Segment der Einlassöffnung des anderen Ausgleichsbehälters gegenüber, so dass auf dieser Seite keine Flüssigkeit in den jeweiligen Ausgleichsbehälter 11 oder 12 gelangen kann.On the other hand, the regulation disc faces the closed segment of the inlet opening of the other expansion tank, so that no liquid can get into the respective expansion tank 11 or 12 on this side.

Am Ende des Schleudervorganges wird das für den Unwuchtausgleich in den Ausgleichsbehältern 11, 12 vorhandene Wasser in den Laugenbehälter 1 abgelassen und von da in den Ablauf transportiert. Alternativ kann das relativ saubere Wasser aber auch im Laugenbehälter verbleiben und für den nächsten Waschgang genutzt werden.At the end of the spin process, the existing for the balancing in the expansion tanks 11, 12 water is drained into the tub 1 and transported from there into the process. Alternatively, the relatively clean water but also remain in the tub and be used for the next wash.
