Description

Die Erfindung betrifft eine Waschmaschine gemäss Oberbegriff von Anspruch 1.The invention relates to a washing machine according to the preamble of claim 1.

Eine derartige Waschmaschine wird z.B. in DE 43 13 819 und US 3 235 082 beschrieben. Sie besitzt an einer Stirnseite der Trommel mehrere Füllringe, von denen jeder mit einem an der Peripherie der Trommel angeordneten Tank verbunden ist. Eine stationäre Einspritzvorrichtung dient dazu, in die Füllringe eine Flüssigkeit einzuspritzen, so dass die Tanks einzeln und gezielt gefüllt werden können, um so eine Unwucht in der Trommel zu kompensieren. Damit kann ein ruhigerer Schleuderbetrieb der Maschine erreicht werden.Such a washing machine is eg in DE 43 13 819 and US 3,235,082 described. It has on one end face of the drum a plurality of filling rings, each of which is connected to a arranged at the periphery of the drum tank. A stationary injector serves to inject a liquid into the filling rings, so that the tanks can be filled individually and selectively, so as to compensate for an imbalance in the drum. This allows a quieter spin operation of the machine can be achieved.

Der vorliegenden Erfindung stellt sich die Aufgabe, eine Waschmaschine mit Tanks zur Unwuchtkompensation möglichst einfach aufzubauen.The object of the present invention is to build a washing machine with tanks for unbalance compensation as simple as possible.

Diese Aufgabe wird von der Waschmaschine gemäss unabhängigen Anspruch 1 gelöst. Demgemäss besitzt die Waschmaschine mehrere, an sich bekannte Spülvorrichtungen zum Spülen mehrerer Kammern, wobei die Kammern zur Aufnahme unterschiedlicher Waschreagenzien dienen. Zudem besitzt sie mehrere Zuführvorrichtungen, wobei mit jeder Zuführvorrichtung Flüssigkeit in einen der Tanks zugeführt werden kann. Zum Steuern der Flüssigkeitszufuhr sind Ventile vorgesehen. Anspruchsgemäss speist mindestens ein Teil der Ventile eine der Spülvorrichtungen und eine der Zuführvorrichtungen. Damit können z.B. mit einem Satz von nur drei Ventilen insgesamt drei Tanks und drei Kammern gezielt mit Wasser beliefert werden.This object is achieved by the washing machine according to independent claim 1. Accordingly, the washing machine has a plurality of known rinsing devices for rinsing a plurality of chambers, wherein the chambers serve to accommodate different washing reagents. In addition, it has a plurality of feeding devices, wherein liquid can be supplied to one of the tanks with each feeding device. For controlling the liquid supply valves are provided. According to the claim, at least a part of the valves feeds one of the rinsing devices and one of the feeding devices. Thus, e.g. with a set of only three valves a total of three tanks and three chambers will be specifically supplied with water.

In einer bevorzugten Ausführung der Erfindung stellt sich die Aufgabe, eine Maschine dieser Art bereitzustellen, deren Nutzraum möglichst gross ist.In a preferred embodiment of the invention, the object is to provide a machine of this type, the usable space is as large as possible.

Diese Aufgabe wird durch die Waschmaschine nach Anspruch 7 gelöst. Demgemäss besitzen die Füllringe unterschiedliche Durchmesser, so dass sie in Achsialrichtung überlappend angeordnet werden können, z.B. "ineinander". Auf diese Weise kann in achsialer Richtung Platz eingespart werden.This object is achieved by the washing machine according to claim 7. Accordingly, the filling rings have different diameters, so that they can be arranged overlapping in the axial direction, for example "in one another". In this way space can be saved in the axial direction.

Vorzugsweise ist die Maschine so ausgestaltet, dass bei Überlauf eines Füllrings das Wasser nicht in die äusseren Füllringe fällt, sondern radial nach aussen z.B. bis zur Bottichwand fallen kann. Dadurch kann verhindert werden, dass überlaufendes Wasser in die falschen Tanks läuft und so eine fehlerhafte Unwuchtkompensation bewirkt.Preferably, the machine is designed so that when overflow of a filling ring, the water does not fall into the outer packing rings, but radially outward, for example. can fall to the tub wall. This can prevent overflowing water from running into the wrong tanks, causing erroneous unbalance compensation.

Hierzu können die Füllringe so gestaltet werden, dass die innersten Füllringe die jeweils äusseren Füllringe in achsialer Richtung überragen. Mit anderen Worten erstreckt sich der innerste Füllring also achsial am weitesten von der Trommel weg, der nächst Äussere etwas weniger, etc. Eine weitere Möglichkeit um zu verhindern, dass überlaufendes Wasser in die falschen Tanks läuft, besteht darin, die von der Trommel abgewandten Wände der Füllringe so auszugestalten, dass der Innenrand jeder Wand achsial näher zur Trommel hin liegt als der Aussenrand des radial nächst inneren Füllrings. Hierzu kann z.B. mindestens ein Teil jeder Wand schräg oder gebogen ausgestaltet sein, so dass er an seinem radial inneren Rand mehr gegen die Trommel hin versetzt ist als an seinem radial äusseren Rand.For this purpose, the filling rings can be designed so that the innermost packing rings project beyond the respective outer packing rings in the axial direction. In other words, the innermost filler ring thus extends axially furthest away from the drum, the next outer somewhat less, etc. Another way to prevent overflowing water from running into the wrong tanks is through the walls away from the drum the filler rings so that the inner edge of each wall is axially closer to the drum than the outer edge of the radially next inner filler ring. For this, e.g. at least a portion of each wall be configured obliquely or curved, so that it is offset at its radially inner edge more towards the drum than at its radially outer edge.

Um die Flüssigkeit insbesondere auch bei relativ geringen Drehgeschwindigkeiten möglichst gut in den Füllringen zu halten, sollte die in einen Füllring eintretende Flüssigkeit möglichst schnell in Tangentialrichtung beschleunigt werden. Hierzu können in den Füllringen sich quer zur Tangentialrichtung erstreckende Mitnehmer angeordnet sein.In order to keep the liquid as well as possible in the filling rings even at relatively low rotational speeds, the liquid entering a filling ring should be accelerated as quickly as possible in the tangential direction. For this purpose, can be arranged transversely to the tangential direction driver in the filling rings.

Ebenfalls um die Flüssigkeit insbesondere auch bei relativ geringen Drehgeschwindigkeiten gut in den Füllringen zu halten, kann die trommelseitige Wand der Füllringe derart schräg oder gebogen zur Radialrichtung verlaufen, dass die Flüssigkeit radial nach aussen beschleunigt wird. Wird die Einspritzvorrichtung so angeordnet, dass sie die Flüssigkeit mindestens teilweise gegen diese trommelseitige Wand spritzt, so wird die Flüssigkeit von dort radial nach aussen umgelenkt, so dass sie automatisch zum radial äusserten Bereich der Füllrinne gelenkt wird.Also, in order to keep the liquid well in the filling rings, especially at relatively low rotational speeds, the drum-side wall of the filling rings can run obliquely or bent to the radial direction such that the liquid is accelerated radially outwards. If the injector is arranged so that it injects the liquid at least partially against this drum-side wall, the liquid is deflected from there radially outwards, so that it is automatically directed to the radially outer region of the filling trough.

Vorzugsweise werden die Füllrinnen radial nach aussen zunehmend schmaler. Damit kann dem Umstand Rechnung getragen werden, dass die inneren Füllringe wegen ihres geringen Radius bei konstanter Breite der Füllrinnen ein wesentlich kleineres Fassungsvermögen hätten als die äusseren Füllringe.Preferably, the filling grooves become increasingly narrow radially outwards. This can take into account the fact that the inner packing rings, because of their small radius with a constant width of the filling troughs, would have a much smaller capacity than the outer packing rings.

Vorzugsweise sind die Tanks in den Rippen der Trommel angeordnet. Um ein Hin- und Herschwappen der Flüssigkeit in Längsrichtung der Tanks zu verhindern, sind in den Tanks eine achsiale Strömung der Flüssigkeit behindernde Dämpfungselemente angeordnet.Preferably, the tanks are arranged in the ribs of the drum. In order to prevent a back and forth sloshing of the liquid in the longitudinal direction of the tanks, an axial flow of the liquid obstructing damping elements are arranged in the tanks.

Die in Fig. 1 dargestellte Waschmaschine besitzt eine Trommel 1 mit horizontaler Drehachse 2. Die Trommel 1 ist in einem Bottich 3 angeordnet. Am Bottich 3 ist ein Motor 4 befestigt, der über einen Riemen 5 und ein Riemenrad 6 die Trommel in bekannter Weise zur Drehung antriebt. Der Bottich 3 ist mit einer Federung schwingend in der Waschmaschine gelagert.In the Fig. 1 The washing machine shown has a drum 1 with a horizontal axis of rotation 2. The drum 1 is arranged in a tub 3. On the tub 3, a motor 4 is fixed, which drives the drum via a belt 5 and a pulley 6 in a known manner for rotation. The tub 3 is mounted with a suspension swinging in the washing machine.

Am Bottich sind Beschleunigungssensoren 7 befestigt, welche es erlauben, beim Schwingen der Wäsche eine Unwucht der Trommel festzustellen. Anstelle von oder Zusätzlich zu den Beschleunigungssensoren 7 können z.B. Winkelgeschwindigkeitssensoren und/oder Abstandssensoren verwendet werden.At the tub acceleration sensors 7 are fixed, which allow it to determine when swinging the laundry an imbalance of the drum. Instead of or in addition to the acceleration sensors 7, e.g. Angular velocity sensors and / or distance sensors are used.

Wie z.B. in DE 43 13 819 beschrieben, wird einer Unwucht in der Trommel entgegengewirkt, indem in spezielle, an der Trommel angebrachte Tanks gezielt eine Flüssigkeit, im vorliegenden Fall Wasser, eingespritzt wird.Like in DE 43 13 819 described, an imbalance in the drum is counteracted by specifically in a specific, attached to the drum tanks, a liquid, in the present case water, is injected.

In der dargestellten Ausführung sind drei Tanks 10 vorgesehen, welche in den Rippen 11 der Trommel 1 angeordnet sind. Jeder Tank 10 erstreckt sich z.B. mit seiner Längsachse über die ganze achsiale Länge der Trommel 1. An der hinteren Stirnseite 12 der Trommel 1 sind drei Füllringe 13a, b und c angeordnet. Die Füllringe sind koaxial, wobei Füllring 13a den kleinsten Durchmesser, Füllring 13b den nächst grösseren Durchmesser und Füllring 13c den grössten Durchmesser aufweist.In the illustrated embodiment, three tanks 10 are provided, which are arranged in the ribs 11 of the drum 1. Each tank 10 extends e.g. with its longitudinal axis over the entire axial length of the drum 1. At the rear end face 12 of the drum 1, three filling rings 13a, b and c are arranged. The filling rings are coaxial, wherein filling ring 13a has the smallest diameter, filling ring 13b has the next largest diameter and filling ring 13c has the largest diameter.

Jeder der Füllringe steht über ein Füllrohr 14 mit je einem der Tanks 10 in Verbindung.Each of the filling rings is connected via a filling tube 14 with one of the tanks 10 in combination.

Eine stationäre Einspritzvorrichtung 16 ist vorgesehen, um Wasser in die Füllringe einzuspritzen. Sie umfasst einen Wasserzulauf 17, der Wasser an drei Ventile 18 liefert. Von den Ventilen 18 gelangt das Wasser über eine Fallstrecke 19 zu je einem Schlauch 20, wobei die Fallstrecke 19 ein Rückfliessen von Wasser in den Wasserzulauf 17 verhindert. Die Schläuche 20 enden in Düsen 21, von denen das Wasser in die einzelnen Füllringe 13a,b,c gespritzt wird. Die Düsen 21 sind am Bottich 3 bzw. am schwingenden System der Waschmaschine angebracht.A stationary injector 16 is provided to inject water into the packing rings. It comprises a water inlet 17 which supplies water to three valves 18. From the valves 18, the water passes through a drop section 19 to a respective tube 20, wherein the drop section 19 prevents backflow of water into the water inlet 17. The hoses 20 terminate in nozzles 21, of which the water in the individual packing rings 13a, b, c is injected. The nozzles 21 are mounted on the tub 3 and on the oscillating system of the washing machine.

In Fig. 2 und 3 sind insbesondere die drei Tanks 10 ersichtlich, welche die Rippen 11 der Trommel 1 bilden. Wie dargestellt, sind die Aussenseiten dieser Rippen 11 nicht glatt, sondern weisen eine Vielzahl von Erhöhungen 25 bzw. dazwischen liegenden Vertiefungen 26 auf. Die Erhöhungen überragen die durchschnittliche Oberfläche z.B. um 1 bis 5 mm und besitzen typische Breiten von z.B. 5 bis 20 mm. Im vorliegenden Ausführungsbeispiel sind die Erhöhungen etwa rund, sie können jedoch z.B. auch länglich oder gratförmig sein, wobei in diesem Fall die Längsachse möglichst in tangentialer Richtung der Trommel angeordnet sein sollte. Die Erhöhungen 25 bzw. Vertiefungen 26 begünstigen einen Abfluss der aus der Wäsche austretenden Flüssigkeit, indem dank der Unregelmässigkeit der Rippenoberfläche Staus von Wasser zwischen Oberfläche und Rippe vermieden werden.In Fig. 2 and 3 In particular, the three tanks 10 can be seen, which form the ribs 11 of the drum 1. As shown, the outer sides of these ribs 11 are not smooth, but have a plurality of elevations 25 or intermediate depressions 26. The elevations project beyond the average surface, for example by 1 to 5 mm and have typical widths of eg 5 to 20 mm. In the present embodiment, the elevations are approximately round, but they may, for example, be oblong or conical, in which case the longitudinal axis should be arranged as far as possible in the tangential direction of the drum. The elevations 25 or depressions 26 favor a drainage of the liquid emerging from the laundry, in that congestion of water between the surface and the rib is avoided, due to the irregularity of the ribbed surface.

Wie aus Fig. 6 ersichtlich, sind in den Tanks 10 Dämpfungselemente 28 angeordnet. Diese besitzen die Form von Wänden, welche quer zur Längsrichtung der Tanks angeordnet sind. Sie behindern ein freies Strömen des Wassers in Längsrichtung der Tanks und dämpfen so ein Hin- und Herschwappen der Flüssigkeit.How out Fig. 6 can be seen, 10 damping elements 28 are arranged in the tanks. These have the form of walls, which are arranged transversely to the longitudinal direction of the tanks. They hinder a free flow of water in the longitudinal direction of the tanks, thus dampening a back and forth sloshing of the liquid.

Die Füllrohre 14, über welche die Tanks 10 mit ihrem jeweiligen Füllring 13a, 13b bzw. 13c verbunden werden, sind insbesondere aus Fig. 2 und 3 ersichtlich. Parallel zu den Füllrohren 14 verlaufen Entlüftungsrohre 28, welche sich ausgehend von den Tanks 10 in radialer Richtung nach innen erstrecken und in Öffnungen 29 münden. Sie erlauben ein Entweichen von Luft aus den Tanks 10 wenn Wasser eingefüllt wird und helfen auch beim Entleeren der Tanks 10. Die Öffnungen 29 sind dabei so weit entfernt von der Peripherie der Trommel 1 angeordnet, dass sie im normalen Waschbetrieb immer über dem Spiegel der Waschlauge liegen. So wird verhindert, dass sich die Tanks 1 mit Waschlauge füllen.The filling tubes 14, via which the tanks 10 are connected to their respective filling ring 13a, 13b or 13c, are in particular made Fig. 2 and 3 seen. Vent tubes 28, which extend inwards in the radial direction from the tanks 10 and open into openings 29 run parallel to the filling tubes 14. They allow escape of air from the tanks 10 when water is filled and also help to empty the tanks 10. The openings 29 are arranged so far away from the periphery of the drum 1, that they are always above the level of the wash liquor in the normal washing operation. This prevents the tanks 1 from filling with wash liquor.

Der Aufbau der Füllringe 13a, 13b, 13c ist am besten aus Fig. 3 - 5 und 7 ersichtlich. Sie werden von einem Ringkörper 30 gebildet, der an der hinteren Stirnseite der Trommel 1 anliegt. Jeder Füllring bildet eine Rinne 31 (Fig. 5), welche auf ihrer der Trommel 1 abgewandten Seite von einem Rand bestehend aus einer sich ungefähr radial nach oben erstreckenden Wand 32 begrenzt wird.The structure of the filling rings 13a, 13b, 13c is best Fig. 3-5 and 7 seen. They are formed by an annular body 30, which bears against the rear end side of the drum 1. Each filler ring forms a groove 31 ( Fig. 5 ), which is bounded on its side facing away from the drum 1 by an edge consisting of an approximately radially upwardly extending wall 32.

Wie insbesondere aus Fig. 5 ersichtlich, erstreckt sich der innerste Füllring 13a in achsialer Richtung am weitesten von der Trommel weg, während die äusseren Füllringe 13b, 13c zunehmend zurückversetzt sind. Tritt Wasser aus dem innersten Füllring 13a über die Wand 32 aus, so tropft es radial nach aussen, ohne dass es in einen den äusseren Füllringe fällt. Um ein gutes Abtropfen sicherzustellen, ist an der äusseren, unteren Kante des Füllrings 13a eine Tropfnase 33 vorgesehen, ebenso an den zwei äusseren Füllringen 13b, 13c.As in particular from Fig. 5 As can be seen, the innermost Füllring 13a extends in the axial direction furthest away from the drum, while the outer packing rings 13b, 13c are increasingly recessed. If water exits the innermost filling ring 13a via the wall 32, it drips radially outwards without falling into an outer filling ring. In order to ensure a good dripping, a drip nose 33 is provided on the outer, lower edge of the filling ring 13a, as well as on the two outer filling rings 13b, 13c.

Wie ebenfalls aus Fig. 5 gut ersichtlich, ist der innerste Füllring 13a in achsialer Richtung am breitesten. In der dargestellten Ausführung überragt jeder der beiden inneren Füllringe 13a, 13b die jeweils äusseren Füllringe 13b bzw. 13c in beiden achsialen Richtungen. Vorzugsweise sind die Grössen so gewählt, dass der Radius des jeweiligen Füllrings multipliziert mit der Breite der vom Füllring gebildeten Füllrinne ungefähr konstant ist.Like also out Fig. 5 clearly visible, the innermost filler ring 13a is widest in the axial direction. In the illustrated embodiment, each of the two inner filling rings 13a, 13b projects beyond the respective outer filling rings 13b or 13c in both axial directions. Preferably, the sizes are selected so that the radius of the respective filling ring multiplied by the width of the filling trough formed by the filling ring is approximately constant.

In den Füllringen 13a, 13b, 13c sind Mitnehmer 35 in Form von im wesentlichen radial und quer zur Tangentialrichtung angeordneten Wänden angeordnet (siehe Fig. 5 und 7), welche jede Füllrinne in eine Vielzahl von Kompartiment-artige Rinnenabschnitte 36 unterteilen, siehe insbesondere Fig. 7. Die Rinnenabschnitte 36 stehen miteinander über Verbindungsöffnungen 37 in Verbindung. Diese Verbindungsöffnungen 37, welche am besten aus Fig. 5 ersichtlich sind, werden am tiefsten, d.h. radial äussersten Bereich der Füllrinnen angeordnet, so dass unabhängig vom Wasserstand das Wasser zwischen den Rinnenabschnitten 36 hin- und her fliessen kann.In the filling rings 13a, 13b, 13c drivers 35 are arranged in the form of substantially radially and transversely to the tangential direction arranged walls (see Fig. 5 and 7 ), which divide each filling channel into a plurality of compartment-like channel sections 36, see in particular Fig. 7 , The channel sections 36 communicate with each other via connection openings 37. These connection openings 37, which is best Fig. 5 are visible, are arranged at the lowest, ie radially outermost region of the Füllrinnen so that regardless of the water level, the water between the channel sections 36 can flow back and forth.

Trommelseitig sind die Füllringe von je einer Wand 40 begrenzt. Die Einspritzvorrichtung 16 bzw. die Düsen 21 sind so angeordnet, dass das Wasser gegen diese Wand 40 gespritzt wird. Wie aus Fig. 5 ersichtlich, verläuft Wand 40 abgebogen zur Radialrichtung, und zwar so, dass das von der Düse 21 auf die Wand 40 spritzende Wasser radial nach aussen beschleunigt wird und so in den radial äussersten Bereich der Füllrinne gelangt. Damit wird der Verlust durch wegspritzendes Wasser minimiert.On the drum side, the filling rings are each bounded by a wall 40. The injection device 16 or the nozzles 21 are arranged so that the water is sprayed against this wall 40. How out Fig. 5 As can be seen, wall 40 is bent away from the radial direction, in such a way that the splashing from the nozzle 21 to the wall 40 water is accelerated radially outwards and thus enters the radially outermost region of the filling channel. Thus, the loss is minimized by wegspritzendes water.

Die Wand 40 kann auch abgeschrägt anstatt gebogen verlaufen.The wall 40 may also be tapered rather than curved.

Wie insbesondere aus Fig. 5 ersichtlich, wird der radial äusserste Bereich der beiden inneren Füllringe 13a, 13b von der trommelseitigen Wand 40 der jeweils nächst äusseren Füllrings 13b bzw. 13c begrenzt. Damit ergibt sich trotz der grossen radialen Tiefe der Füllrinnen ein kompakter Aufbau.As in particular from Fig. 5 can be seen, the radially outermost region of the two inner Füllringe 13a, 13b bounded by the drum-side wall 40 of each next outer Füllrings 13b and 13c. This results in spite of the large radial depth of the Füllrinnen a compact design.

Fig. 8 zeigt eine vorteilhafte Ausgestaltung der Wasserzuführungen, wie sie z.B. für die oben beschriebene Waschmaschine, aber auch für andere Waschmaschinen mit Tanks zum Ausgleichen einer Unwucht eingesetzt werden kann. Fig. 8 shows an advantageous embodiment of the water supplies, as can be used for example for the washing machine described above, but also for other washing machines with tanks to compensate for an imbalance.

Bei der in Fig. 8 gezeigten Vorrichtung handelt es sich um die Wasserzuführung für einen der Tanks 10 und für eine Kammer 50. Die Kammer 50 dient dabei zur Aufnahme eines Waschreagens. In der Regel besitzen Waschmaschinen drei derartige Kammern, eine davon zur Aufnahme des im Vorspülgang zuzugebenden Waschmittels, eine zur Aufnahme des im Hauptspülgang zuzugebenden Waschmittels und eine zur Aufnahme des im Weichspülgang zuzugebenden Weichspülers. Jede dieser Kammern muss einzeln gespült werden können, so dass das jeweilige Waschreagens über eine Leitung 51 dem Bottich 3 zugeführt werden kann.At the in Fig. 8 The device shown is the water supply for one of the tanks 10 and for a chamber 50. The chamber 50 serves to receive a washing reagent. In general, washing machines have three such chambers, one of them for receiving the detergent to be added in the pre-rinse cycle, one for receiving the detergent to be added in the main rinse and one for receiving the softener to be added softener. Each of these chambers must be rinsed individually can be, so that the respective washing reagent can be supplied via a line 51 to the tub 3.

Wie im folgenden beschrieben wird, kann mit der Anordnung nach Fig. 8 mit nur einem Ventil eine der Kammern 50 und einer der Tanks 10 mit Wasser versorgt werden.As will be described below, with the arrangement according to Fig. 8 with only one valve one of the chambers 50 and one of the tanks 10 are supplied with water.

Das entsprechende Ventil 18 sitzt in einem Ventilsitz 52 und kann über einen Magneten 53 betätigt werden. Wird das Ventil 18 zurückgezogen, so kann Wasser von einer Zufuhrleitung 54 in einen Vorraum 55 strömen.The corresponding valve 18 is seated in a valve seat 52 and can be actuated by a magnet 53. If the valve 18 is withdrawn, water can flow from a supply line 54 into an antechamber 55.

Der Vorraum 55 hat mindestens einen ersten Ausgang 56, welcher im Luftspalt 19 mündet (vgl. auch Fig. 1). Das aus dem Ausgang 56 und durch den Luftspalt 19 fallende Wasser wird von einem Trichter 57 aufgefangen und in einen der Schläuche 20 geführt, die das Wasser in die Füllringe 13a, 13b, 13c eintragen.The antechamber 55 has at least one first outlet 56, which opens in the air gap 19 (see also Fig. 1 ). The water falling from the outlet 56 and through the air gap 19 is collected by a funnel 57 and led into one of the hoses 20, which enter the water in the filling rings 13a, 13b, 13c.

Weiter besitzt der Vorraum 55 mindestens einen zweiten Ausgang 60, durch welchen das Wasser in die Kammer 50 fliessen kann. In der in Fig. 8 dargestellten Ausführung, tritt das durch den Ausgang 60 austretende Wasser in eine Brause 61 über der Kammer 50. Die Brause 61 besitzt Öffnungen 62, durch welche das Wasser in die Kammer 50 fliesst.Next, the vestibule 55 has at least one second outlet 60, through which the water can flow into the chamber 50. In the in Fig. 8 In the illustrated embodiment, the water exiting through the outlet 60 enters a shower 61 above the chamber 50. The shower 61 has openings 62 through which the water flows into the chamber 50.

Vorzugsweise ist der erste Ausgang 56 tiefer als der zweite Ausgang 60 angeordnet, so dass durch das Ventil 18 in den Vorraum 55 eintretendes Wasser zuerst nur durch den ersten Ausgang 56 fliesst. Der erste Ausgang 56 sollte aber so bemessen sein, dass er bei den normalerweise im Vorraum 55 auftretenden Druckverhältnissen nicht alles des bei offenem Ventil 18 einfliessenden Wassers abzuführen vermag, so dass der Wasserspiegel 65 im Vorraum 55 ansteigt, bis entweder das Ventil 18 abgeschaltet wird oder das Wasser den zweiten Ausgang 60 erreicht.Preferably, the first exit 56 is located lower than the second exit 60, so that water entering the vestibule 55 through the valve 18 first flows through the first exit 56 only. The first output 56 should, however, be dimensioned such that it can not dissipate all of the water flowing in with the valve 18 open during the pressure conditions normally occurring in the antechamber 55, so that the water level 65 in the antechamber 55 rises until either the valve 18 is switched off or the water reaches the second exit 60.

Die Waschmaschine ist nun so ausgestaltet, dass sie das Ventil 18 nur teilweise oder nur stossweise öffnet, wenn das Wasser zur Unwuchtkompensation eingesetzt werden soll. Dabei wird die Wassermenge pro Zeiteinheit so eingestellt, dass der Wasserspiegel 65 im Vorraum 55 die Höhe des zweiten Ausgangs 60 nicht erreicht, so dass alles Wasser über die erste Öffnung 56 abfliesst. Soll das Wasser zum Spülen der Kammer 50 verwendet werden, so wird das Ventil 18 voll bzw. dauernd geöffnet. In diesem Fall erreicht der Wasserspiegel 65 nach kurzer Zeit auch den zweiten Ausgang, so dass die Kammer 50 gespült wird. Zwar tritt dann das Wasser immer noch auch durch den ersten Ausgang aus, was jedoch während der Spülphase der Kammer 50 nicht weiter stört.The washing machine is now designed so that it opens the valve 18 only partially or only in blocks, when the water used for unbalance compensation shall be. The amount of water per unit of time is adjusted so that the water level 65 in the antechamber 55 does not reach the height of the second outlet 60, so that all water flows off via the first opening 56. If the water is used to flush the chamber 50, the valve 18 is fully opened. In this case, the water level 65 reaches after a short time, the second output, so that the chamber 50 is purged. Although then the water still exits through the first output, but this does not interfere during the rinsing phase of the chamber 50.

Vorzugsweise besitzt der erste Ausgang 56 einen wesentlich kleineren Querschnitt (z.B. 5 x kleiner) als der zweite Ausgang 60, so dass bei voll geöffnetem Ventil 18 verhältnismässig wenig Wasser durch die erste Öffnung 56 austritt und möglichst viel Wasser zum Spülen der Kammer 50 zur Verfügung steht.Preferably, the first outlet 56 has a substantially smaller cross-section (eg, 5 times smaller) than the second outlet 60, so that when the valve 18 is fully open, relatively little water exits through the first opening 56 and as much water as possible is available to rinse the chamber 50 ,

Konkret kann z.B. das Ventil zum Füllen eines der Tanks 10 während Pulsen von 30 bis 50 ms geöffnet werden, wobei es so bemessen ist, dass dabei pro Puls eine Wassermenge von z.B. 70 ml in den Vorraum 55 einfliesst. Der Vorraum 55 ist so ausgestaltet, dass bei dieser Wassermenge der Wasserpegel 65 den oberen Ausgang 60 noch nicht erreicht. Der erste Ausgang 56 ist so dimensioniert, dass er bei Normaldruck eine Wassermenge von ca. 0.8 1/min passieren lässt, so dass die in einem Puls in den Vorraum 55 eingetragene Wassermenge in rund 100 ms abgeführt wird. Sodann kann, falls nötig, der nächste Puls des Ventils 18 erfolgen. Soll die Kammer 50 geflutet werden, so wird das Ventil 18 dauernd geöffnet, in welchem Fall z.B. eine Wassermenge 10 1/min in den Vorraum 55 einfliesst. Diese Wassermenge kann vom ersten Ausgang 56 nicht abgeführt werden, so dass der Wasserpegel 65 steigt, bis Wasser durch den wesentlich grösseren zweiten Ausgang 60 austreten kann.Concretely, e.g. the valve for filling one of the tanks 10 is opened during pulses of 30 to 50 ms, wherein it is dimensioned such that per pulse a quantity of water of e.g. 70 ml flows into the vestibule 55. The vestibule 55 is designed so that at this amount of water, the water level 65 does not reach the upper output 60 yet. The first output 56 is dimensioned so that it can pass at atmospheric pressure, an amount of water of about 0.8 1 / min, so that the registered in a pulse in the vestibule 55 amount of water is discharged in about 100 ms. Then, if necessary, the next pulse of the valve 18 take place. If the chamber 50 is to be flooded, the valve 18 is opened permanently, in which case e.g. an amount of water 10 1 / min flows into the vestibule 55. This amount of water can not be removed from the first output 56, so that the water level 65 increases until water can escape through the much larger second outlet 60.

Es ist auch denkbar, beide Ausgänge 56, 60 auf etwa gleicher Höhe anzuordnen, in welchem Fall das Wasser entsprechend der Durchmesser der Ausgänge auf den Tank 10 und die Kammer 50 verteilt wird.It is also conceivable to arrange both outputs 56, 60 at approximately the same height, in which case the Water according to the diameter of the outputs to the tank 10 and the chamber 50 is distributed.

Weiter ist es auch möglich, den Ventilen 18 eine für alle Ventile gemeinsam betätigbare Steuerklappe nachzuschalten, die das Wasser gezielt entweder in die Kammern 50 oder die Tanks 10 leitet.Furthermore, it is also possible for the valves 18 to be followed by a control flap that can be actuated jointly for all valves, which directs the water selectively into either the chambers 50 or the tanks 10.

In der insbesondere in Fig. 5 dargestellten Ausführung, erstrecken sich die Füllringe achsial weiter von der Trommel weg, je weiter innen sie liegen, damit ein Überlaufen von Wasser auf einem Füllring nicht zu einem Füllen eines nächst äusseren Füllrings führt.In particular in Fig. 5 illustrated embodiment, the filling rings extend axially away from the drum, the further inside they lie so that overflow of water on a filling ring does not lead to a filling of a next outer filler ring.

Fig. 9 zeigt eine andere Möglichkeit, den gleichen Effekt mit einem kompakteren Aufbau zu erreichen. Hier sind die von der Trommel abgewandten Ränder bzw. Wände 32 der Füllringe so ausgestaltet, dass der Innenrand 70 jeder Wand 32 (d.h. der in radialer Richtung innere Rand der Wand 32) achsial näher zur Trommel 1 hin liegt als der Aussenrand 70 des radial nächst inneren Füllrings. Um dies zu erreichen, ist in Fig. 9 ein innerster Teil 72 der Aussenseite jeder Wand 32 zur Trommel 1 hin abgeschrägt (oder gebogen) ausgestaltet. Fig. 9 shows another way to achieve the same effect with a more compact design. Here are the edges facing away from the drum or walls 32 of the filling rings configured so that the inner edge 70 of each wall 32 (ie the radially inner edge of the wall 32) is axially closer to the drum 1 out as the outer edge 70 of the radially next inner filler ring. To achieve this is in Fig. 9 an innermost part 72 of the outside of each wall 32 is tapered (or bent) towards the drum 1.
