Definitions
- the invention relates to a washing machine according to the preamble of claim 1.
- 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.
- the object of the present invention is to build a washing machine with tanks for unbalance compensation as simple as possible.
- 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.
- the chambers serve to accommodate different washing reagents.
- it has a plurality of feeding devices, wherein liquid can be supplied to one of the tanks with each feeding device.
- liquid supply valves are provided.
- at least a part of the valves feeds one of the rinsing devices and one of the feeding devices.
- the object is to provide a machine of this type, the usable space is as large as possible.
- 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.
- 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.
- the filling rings can be designed so that the innermost packing rings project beyond the respective outer packing rings in the axial direction.
- 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.
- 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.
- the liquid entering a filling ring should be accelerated as quickly as possible in the tangential direction.
- the liquid entering a filling ring should be accelerated as quickly as possible in the tangential direction.
- 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.
- 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.
- the tanks are arranged in the ribs of the drum.
- an axial flow of the liquid obstructing damping elements are arranged in the tanks.
- the washing machine shown has a drum 1 with a horizontal axis of rotation 2.
- the drum 1 is arranged in a 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.
- 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.
- 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.
- three filling rings 13a, b and c are arranged at the rear end face 12 of the drum 1.
- 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.
- Each of the filling rings is connected via a filling tube 14 with one of the tanks 10 in combination.
- 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.
- the three tanks 10 can be seen, which form the ribs 11 of the drum 1.
- 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.
- 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.
- 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.
- 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.
- 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.
- the innermost Golfring 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.
- the innermost filler ring 13a is widest in the axial direction.
- each of the two inner filling rings 13a, 13b projects beyond the respective outer filling rings 13b or 13c in both axial directions.
- 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.
- 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.
- connection openings 37 which is best Fig. 5 are visible, are arranged at the lowest, ie radially outermost region of the Grerinnen so that regardless of the water level, the water between the channel sections 36 can flow back and forth.
- 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.
- 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.
- the loss is minimized by wegspritzendes water.
- the wall 40 may also be tapered rather than curved.
- 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.
- 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.
- 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.
- 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.
- 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.
- the vestibule 55 has at least one second outlet 60, through which the water can flow into the chamber 50.
- 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.
- 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.
- 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.
- 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 ,
- 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.
- 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.
- both outputs 56, 60 are 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.
- valves 18 may 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.
- 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 shows another way to achieve the same effect with a more compact design.
- 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.
- an innermost part 72 of the outside of each wall 32 is tapered (or bent) towards the drum 1.

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
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
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.

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.
