Es wird üblicherweise eine federnde Aufhängung des Laugengehäuses gegenüber dem Gehäuse der Waschmaschine berücksichtigt.The invention relates to a washing machine, or washer-dryer od. Like., With a washing drum in a lye housing, wherein the washing drum is rotatably mounted in the lye housing, that the lye housing against an outer housing of the washing machine, is guided or suspended, and that the washing machine a first drive for rotation of the drum with respect to the lye housing. It is usually considered a resilient suspension of the lye housing relative to the housing of the washing machine.
Bei Waschmaschinen gibt es grundlegende Betrachtungen, wie eine zugrunde zu legende Waschzeit, die Menge und Art der einzubringenden Waschmittel, auch mit Stichwort Chemie zu bezeichnen, die zugrunde zu legende Temperatur, also die einzubringende Energie sowie die auszulösende mechanische Bewegung der Wäsche in einer Waschtrommei, auch beschrieben mit dem Stichwort eingebrachte Mechanik, in Beziehung zueinander zu bringen sind, um eine optimales Waschergebnis bzw eine gewünschte Waschperformance zu erreichen. Im Fachgebiet wird dies mit dem so genannten Sinnerschen Kreis beschrieben, wonach es gilt, dass ein Gleichgewicht aus Waschzeit, eingebrachter Mechanik Chemie und Temperatur bzw. Energie bestehen muss, um eine gleich gute Waschperformance zu erreichen.In washing machines, there are fundamental considerations, such as an underlying washing time, the amount and type of detergent to be introduced, also referred to by chemistry, the underlying temperature, so the energy to be introduced as well as the triggering mechanical movement of the laundry in a Waschtrommei, also described with the keyword introduced mechanics, are related to each other in order to achieve an optimal washing result or a desired washing performance. In the field, this is described by the so-called Sinner's Circle, which states that a balance of washing time, applied chemistry mechanics and temperature or energy must exist in order to achieve an equally good wash performance.
Es ist auch bekannt, dass bei in der Waschtrommel wegen ungleich verteilter Wäsche, insbesondere bei einem Schleudervorgang, Gegenmaßnahmen ergriffen werden müssen, damit eine in einem Haushalt aufgestellte Waschmaschine nicht so stark zu schwingen beginnt, dass sie sozusagen wegwandert.It is also known that in the washing drum because of unequally distributed laundry, especially in a spin process, countermeasures must be taken so that a set up in a household washing machine does not begin to vibrate so strong that they walk away, so to speak.

Eine Aufhängevorrichtung für ein elastisch gelagertes Trommelgehäuse einer Wascheinrichtung ist aus
Im Vorfeld der Erfindung wurden Überlegungen angestellt, welche Möglichkeiten bestehen könnten, die Waschperformance zu verbessern, ohne dabei die Waschzeit, die eingebrachte Chemie oder die eingebrachte Energie in ungünstigem Sinne verändern zu müssen.In the run-up to the invention considerations were made as to which possibilities could exist for improving the washing performance without having to change the washing time, the introduced chemistry or the introduced energy in an unfavorable sense.
Die Aufgabe der Erfindung besteht daher darin, eine Waschmaschine, auch Waschtrockner od. dgl. anzugeben, die die so genannte eingebrachte Mechanik zur Verbesserung der Waschperformance heranzieht. Ebenso soll ein hierzu gehörendes Verfahren zählen, nach dem eine solche Waschmaschine zu betreiben ist.The object of the invention is therefore to provide a washing machine, also a washer-dryer or the like, which uses the so-called introduced mechanism to improve the washing performance. Likewise, a belonging to this process is to operate according to such a washing machine.
Bezüglich der Vorrichtung wird diese Aufgabe dadurch gelöst, dass ein mindestens zweiter Antrieb für eine lineare Bewegung des Laugengehäuses und der Trommel in Bezug auf das Gehäuse der Waschmaschine vorgesehen ist.With regard to the device, this object is achieved in that an at least second drive is provided for a linear movement of the lye housing and the drum with respect to the housing of the washing machine.
Mit einem solchen zweiten Antrieb kann hinzukommend zu der Bewegung, die die Wäsche durch die, auch reversierende, Drehung der Waschtrommel mit deren Rippen erhält und zu einem laufenden Hinabfallen der Wäschestücke in die Wäschelauge des Laugenbehälters führt, eine weitere Bewegung erhalten werden, die nach erster gefundener Erklärung sich als Beschleunigung des Fallvorganges der Wäschestücke in die Lauge erweisen dürfte. Auch wenn im Wesentlichen vertikale (in Bezug auf die im Wesentlichen auf horizontal Bodenfläche aufgestellte Waschmaschine) Bewegungen, durch den mindesten zweiten Antrieb ausgelöst werden, so können auch quer dazu auftretende Bewegungen einen Beitrag zum beschleunigten Waschergebnis liefern, da jede Bewegung zwischen Wäschestück und Lauge für das Reinigungsergebnis der Wäsche förderlich ist.With such a second drive may be added to the movement, which receives the laundry by the, even reversing, rotation of the washing drum with their ribs and leads to a continuous falling of the laundry items in the washing liquor of the tub, a further movement can be obtained after the first found explanation is likely to accelerate the fall of the laundry items in the liquor. Even if substantially vertical (in relation to the substantially horizontal floor surface mounted washing machine) movements are triggered by the least second drive, as well as transversely occurring movements can contribute to the accelerated washing result, since any movement between the laundry and lye for the cleaning result of the laundry is conducive.
Die so stattfindende Beschleunigung des Waschvorganges kann beispielsweise sich in einer Verkürzung der Waschzeit niederschlagen. Jedoch ist es bei gleicher Waschzeit auch möglich den Anteil von Chemie und/oder einen Anteil teurer elektrische Energie zum Aufheizen der Waschlauge zu vermindern. Auf jeden Fall wird erfindungsgemäß die Waschperformance erhöht und zwar um bis zu 30 Prozent.The thus occurring acceleration of the washing process, for example, can be reflected in a shortening of the washing time. However, it is also possible with the same washing time to reduce the proportion of chemistry and / or a share of expensive electrical energy for heating the wash liquor. In any case, the washing performance is increased according to the invention by up to 30 percent.
Da zwar eine Linearbewegung durch eine Umsetzung einer Drehbewegung von einem elektrischen Antrieb, wie einem Elektromotor mit sich drehender Ausgangswelle, in eine Linearbewegung erfolgen kann, wozu eine getriebliche Exzenteranordnung oder ein Ritzel mit zugeordneter Zahnstange dienen könnte, hat es sich als vorteilhaft erwiesen, einen Linearmotor für den mindestens zweiten Antrieb einzusetzen. Dies kann dann entweder ein Tauchanker innerhalb einer diesen umgebenden Magnetspule sein, oder es kann eine Magnetspulen-Anordnung gewählt werden, mit der sich ein sich linear bewegendes Feld (vgl. Transrapid) erzeugen lässt. Mit dieser aufwändigeren Anordnung lassen sich in besonders exakter Weise vorbestimmte Linearbewegungen des Laugenbehälters auslösen. Besteht die Führung des Laugenbehälters innerhalb der Gehäuses der Waschmaschine darin, dass eine federnde Aufhängung des Laugenbehälters gewählt wird, so wird durch den mindestens zweiten Antrieb eine Linearbewegung unter Erhöhung und Herabsetzung der Kraft von Federn der Anordnung zur Aufhängung des Laugengehäuses gegenüber dem Waschmaschinengehäuse ausgeübt.Since a linear movement can take place by a conversion of a rotational movement of an electric drive, such as an electric motor with rotating output shaft in a linear movement, which could serve a geared eccentric or a pinion with associated rack, it has proved to be advantageous to a linear motor for the at least second drive. This can then either be a plunger anchor within a surrounding magnet coil, or a magnet coil arrangement can be selected with which a linearly moving field (see Transrapid) can be generated. With this more complex arrangement can be in particular accurately trigger predetermined linear movements of the tub. Is the leadership of the tub within the housing of the washing machine in that a resilient suspension of the tub is selected, then by the at least second drive a linear movement under increasing and decreasing the force of springs of the arrangement for suspending the tub against the washing machine housing exerted.
Es wird noch darauf hingewiesen, dass ein Antrieb, der zum Beispiel lediglich einen Exzenter aufweist und körperlich mit dem Laugenbehälter verbunden ist, jedoch keine getriebliche Verbindung zu dem Gehäuse der Waschmaschine aufweist, auch schon geeignet ist, die beanspruchte erfindungsgemäße Lehre realisieren zu können, da auch dann eine lineare Bewegung des Laugengehäuses und der Trommel in Bezug auf das Waschmaschinengehäuse sich ausbilden lässt.It should also be noted that a drive which has, for example, only one eccentric and is physically connected to the tub, but has no geared connection to the housing of the washing machine, is also already suitable to realize the claimed teaching of the invention, as even then a linear movement of the tub body and the drum with respect to the washing machine housing can be formed.
Es hat sich als vorteilhaft erwiesen, wenn durch eine Steuerung des weiter oben erwähnten Linearmotors bewirkt wird, dass die Trommel in nahezu vertikaler Richtung um 3 bis 40 mm, vorzugsweise 25 bis 35 mm bezogen auf deren Ruhelage in positivem und negativem Richtungssinn ausgelenkt wird.It has proved to be advantageous if it is effected by a control of the above-mentioned linear motor, that the drum is deflected in a nearly vertical direction by 3 to 40 mm, preferably 25 to 35 mm relative to the rest position in a positive and negative sense.
Ferner hat es sich gezeigt, dass ein Frequenzbereich für die erfindungsgemäße Bewegung der Trommel in nahezu vertikaler Richtung von 0,05 bis 10 Hz, vorzugsweise von 0,1 bis 5 Hz als besonders günstig infrage kommt.Furthermore, it has been shown that a frequency range for the movement of the drum according to the invention in the nearly vertical direction from 0.05 to 10 Hz, preferably from 0.1 to 5 Hz, is considered particularly favorable.
Obwohl der Focus der Erfindung darauf ausgerichtet ist, die Waschperformance zu erhöhen, hat es sich in ganz überraschender Weise gezeigt, dass es für die Beherrschung der Schleuderbetriebsphase dem Grunde nach nicht erforderlich ist Dämpfer (vgl. auch Bezugszeichen 6 der
Die erfinderische Lehre ist auch verwirklicht, wenn der mindestens zweite Antrieb als eine Anordnung von mehreren Linearmotoren, also als ein zweites Antriebssystem zur linearen Auslenkung des Laugengehäuses ausgebildet ist, wobei die mehreren Linearmotoren ausschließlich zur trieblichen Verbindung zwischen dem Laugengehäuse und dem Gehäuse der Waschmaschine vorgesehen sind. Dann erübrigt es sich den Laugenbehälter gegenüber dem Gehäuse der Waschmaschine federnd aufzuhängen, da eine Führung des Laugenbehälters in Bezug auf das Gehäuse der Waschmaschine über den beweglichen Teil bzw. Anker der Linearmotoren erfolgen kann, wobei deren Stationärteil am Gehäuse der Waschmaschine befestigt, insbesondere, bevorzugt mit mehr als einem Freiheitsgrad, drehbeweglich befestigt ist. Bei der Steuerung der Linearmotoren, im Übrigen in dem Auslenkungs- und Frequenzbereich wie auch zuvor angegeben, können sich dann Vorteile ergaben, da die Eigenschaften der ansonsten zur Aufhängung erforderlichen Federn nicht zu berücksichtigen sind.The inventive teaching is also realized when the at least second drive is designed as an arrangement of a plurality of linear motors, that is, as a second drive system for linear deflection of the lye housing, wherein the plurality of linear motors are provided exclusively for driving connection between the lye housing and the housing of the washing machine , Then it is unnecessary to resiliently suspend the tub relative to the housing of the washing machine, since a guide of the tub in relation to the housing of the washing machine via the movable part or anchor of the linear motors can be done, the stationary part attached to the housing of the washing machine, in particular, preferred with more than one degree of freedom, is rotatably mounted. In the control of the linear motors, incidentally in the deflection and frequency range as previously stated, then benefits can be gained because the properties of the springs otherwise required for suspension are not taken into account.
Ebenso ist es möglich, dass bei Einnahme der Schleuder-Betriebsphase durch die Waschmaschine, die Linearmotoren derart steuerbar sind, dass eine Dämpfung der beim Schleudervorgang entstehenden Schwingung von Laugenbehälter und Trommel bewirkt wird. Bei der Steuerung der Linearmotoren ist es vorteilhaft, dass die Charakteristik der ansonsten zur Aufhängung des Laugengehäuses erforderlichen Federn nicht zu berücksichtigen ist. Es wird wiederum ein aktive Dämpfung durch die Steuerung der Linearmotoren bewirkt, so dass dem Grunde nach die herkömmlichen Dämpfer entfallen können. Es steht hier wiederum auch die Möglichkeit einer Energierückspeisung in das Versorgungsnetz an.It is also possible that when taking the spin phase of operation by the washing machine, the linear motors are controlled so that a damping of the resulting during the spinning oscillation of tub and drum is effected. In the control of the linear motors, it is advantageous that the characteristic of the springs otherwise required for suspending the lye housing is not taken into account. In turn, active damping is effected by the control of the linear motors, so that basically the conventional dampers can be dispensed with. Again, there is also the possibility of energy recovery in the supply network.
Die Erfindung wird in verfahrensmäßiger Hinsicht dadurch gelöst, dass bei Vorhandensein eines weiteren Antriebssystems zur linearen Auslenkung des Laugengehäuses und der Trommel gegenüber dem Gehäuse der Waschmaschine das Verfahren bewirkt, dass ein Waschvorgang wirkungsvoller bzw. mit höherer Performance durchgeführt werden kann.In terms of the method, the invention is achieved in that, in the presence of a further drive system for the linear deflection of the lye housing and the drum relative to the housing of the washing machine, the method causes a washing process to be carried out more effectively or with higher performance.
Mit einem solchen zweiten Antriebssystem kann hinzukommend zu der Bewegung, die die Wäsche durch die, auch reversierende, Drehung der Waschtrommel mit deren Rippen erhält und zu einem laufenden Hinabfallen der Wäschestücke in die Wäschelauge des Laugenbehälters führt, eine weitere Bewegung erhalten werden.With such a second drive system can be added to the movement that the laundry through the, even reversing, rotation of the washing drum with the ribs receives and leads to a continuous falling down of the laundry items in the washing liquor of the tub, a further movement can be obtained.
Die durch die weitere Bewegung sich ergebende Beschleunigung des Waschvorganges kann beispielsweise sich in einer Verkürzung der Waschzeit niederschlagen. Jedoch ist es bei gleicher Waschzeit auch möglich den Anteil von Chemie und/oder einen Anteil teurer elektrische Energie zum Aufheizen der Waschlauge zu vermindern. Auf jeden Fall wird erfindungsgemäß die Waschperformance erhöht.The acceleration of the washing process resulting from the further movement can, for example, be reflected in a shortening of the washing time. However, it is also possible with the same washing time to reduce the proportion of chemistry and / or a share of expensive electrical energy for heating the wash liquor. In any case, the washing performance is increased according to the invention.
Es ist dabei vorgesehen, dass die Trommel in einer Richtung quer zu deren Drehachse, insbesondere nahezu vertikaler Richtung, um 3 bis 40 mm, vorzugsweise 25 bis 35 mm bezogen auf deren Ruhelage in positivem und negativem Richtungssinn ausgelenkt wird, wobei ein Frequenzbereich von 0,05 bis 35 Hz, wobei eine Frequenz von 35 Hz eine Trommeldrehzahl von 2100 1/min entspricht. Vorzugsweise wird für einen Betrieb der Waschmaschine bei einem Waschvorgang ein Frequenzbereich von 0,05 Hz bis 10 Hz, insbesondere von 0,1 bis 5 Hz, und bei einem Schleudervorgang eine Frequenz von bis zu 35 Hz vorgesehen.It is provided that the drum is deflected in a direction transverse to its axis of rotation, in particular nearly vertical direction, by 3 to 40 mm, preferably 25 to 35 mm relative to its rest position in a positive and negative sense, wherein a frequency range of 0, 05 to 35 Hz, with a frequency of 35 Hz corresponds to a drum speed of 2100 1 / min. Preferably, for operation of the washing machine in a washing process, a frequency range of 0.05 Hz to 10 Hz, in particular from 0.1 to 5 Hz, and provided in a spin operation, a frequency of up to 35 Hz.

Die bei der Schwingung entstehende Energie kann in das Versorgungsnetz zurückgeführt werden.When the washing machine, the washer-dryer.

Ein Schwerpunkt 14 des Laugenbehälter-Schwingungssystems resultiert aus der Massenverteilung im Laugebehälter 3, wobei durch die Konstruktion der Waschmaschine meist erreicht wird, dass der Schwerpunkt 14 bevorzugt auf der Drehachse 13 der Trommel 8 und einer von den Anbindungspunkten der Federn 9, 9' und des bzw. der Linearmotore 6, 6' gebildeten Ebene liegt.In
A center of
Die Waschmaschine 1 verfügt auch über eine Programmsteuerung 10, der Signale von mehreren Messstellen, wie auch einer Messeinrichtung 2, die Lage- Veränderungen des Laugenbehälters 3 in Bezug auf die Waschmaschine 1 bzw. deren Gehäuse zu erfassen vermag, zugeführt werden.The washing machine 1 also has a
Die Programmsteuerung 10 steht auch über eine oder mehrere Signalleitungen 10' mit einer Antriebssteuerung 20 in Verbindung, die nach Vorgaben der Programmsteuerung 10 die an den ersten Antrieb 5 zur Drehung der Wäschetrommel und an den mindestens zweiten Antrieb, insbesondere an Linearmotore 6 und 6' zur Erreichung einer unterschiedlichen Lage des Laugenbehälters 3 in Bezug auf die Waschmaschine 1 bzw. deren Gehäuse 1 a, erforderliche Leistung über Leitungen 21 und 22 bzw. 22' auszugeben vermag.The
Der erste Antrieb 5 zur Drehung der Wäschetrommel 8 erhält die erforderliche Leistung in üblicher Weise durch das Zusammenwirken von Programmsteuerung 10 und der Antriebsteuerung, wie hier mit 20 bezeichnet. Es werden insbesondere die Drehzahlen der Trommel 8 für Phasen des Waschvorganges und die Phasen von Schleudervorgängen eingestellt bzw. geregelt. Da dies grundsätzlich bekannt ist, wird dies nicht weiter erläutert.The first drive 5 for rotating the
Der mindestens zweite Antrieb, also Linearmotore 6 und 6' die geometrisch örtlich, wie obig dargestellt, die Lage der sonst üblichen Dämpfer einnehmen, soll bei einem Waschvorgang eine zusätzliche, lineare Bewegung der Wäschetrommel auslösen.The at least second drive, so linear motors 6 and 6 'occupy the geometric local, as shown above, the location of the usual damper, to trigger in a washing process, an additional, linear movement of the laundry drum.
Obwohl Linearmotore sich sehr einfach durch einen in einen ringzylindrischen Stator mit eintauchbarem Weicheisenanker aufbauen lassen, ist nachfolgend bevorzugt vorgesehen, dass Linearmotore durch ein mehrphasiges Ständermagnetfeld gebildet werden, so dass dessen Anker entsprechend dem linearen Wandern des Ständermagnetfeldes eine ziemlich genaue, über die Steuerung vorgegebene Stellung einnehmen kann. Durch entsprechende Abstimmung/ größenmäßige Auslegung der Linearmotore 6, 6' ist es also auch möglich, über die Antriebssteuerung 20, die über Steuerungsteile mit abgehenden Leitungen 22, 22' für die Speisung der Linearmotore 6, 6' verfügt, im Betrieb der Waschmaschine bei einem Waschvorgang das obige herausgestellte schwingungsfähige Laugenbehältersystem, so in Schwingung zu versetzen, dass in ungefährer vertikaler Richtung bzw. z-Richtung eine Amplitude von 3 bis 40 mm, vorzugsweise von 25 bis 35 mm der Schwingung entsteht, während dabei eine Frequenz von 0,05 Hz bis 10 Hz, bevorzugt von 0,1 bis 5 Hz ausbildet. Auslenkungen in y-Richtung - soweit die Konstruktion der Waschmaschine es zulässt - werden zwar nicht primär angestrebt, tragen jedoch, wenn sie auftreten, auch zum Waschvorgang bei. Dabei wird auch berücksichtigt, dass die Dynamik der Schwingung über die Messeinrichtung 2 am Laugenbehälter sich in hervorragender Weise auf die Erfordernisse des über die Programmsteuerung 10 ausgewählten Waschprogramms abstimmen lässt. Es versteht sich von selbst, dass die Elastomer-Manschette 7 zwischen dem Laugenbehälter 3 und dem Gehäuse 1 a der Waschmaschine 1 bezüglich der Dimensionierung und der Materialwahl auf diese Schwingungssituation hin auszulegen ist. Im Übrigen wird festgestellt, dass die Waschperformance sich die durch die über die Linearmotoren 6 und 6' eingebrachte bzw. angeregte Schwingung des schwingungsfähigen Laugenbehältersystems, in vorbestimmter Weise beeinflussen bzw. erhöhen lässt und zwar um bis zu 30%. Es kann also bei gleich verschmutzten Wäschestücken ein Waschvorgang in kürzerer Zeit durchgeführt werden oder es können Teile der Waschmittelmenge oder eingebrachte elektrische Energie für das Aufheizen der Waschlauge eingespart werden. Dabei darf man sich auch darauf stützen, dass der Einsatz elektrischer Energie zum Erhalt elektromotorisch ausgelöster Bewegungen stets äußerst energieeffizient abläuft.Although linear motors can be easily constructed by a in a ring cylindrical stator with immersed soft iron anchor, it is preferably provided below that linear motors are formed by a multi-phase stator magnetic field, so that its armature in accordance with the linear migration of the stator magnetic field a fairly accurate, predetermined by the control position can take. By appropriate vote / size design of the linear motors 6, 6 'so it is also possible, via the
Bekanntlicherweise wird das schwingungsfähige Laugenbehältersystem bei einem Schleudervorgang durch meist ungleich in der Trommel verteilte Wäsche W von selbst sehr stark zum Schwingen angeregt. Es gibt zahlreiche Ansätze, wie diese Unwucht durch geeignete Maßnahmen reduziert werden kann. Es kann zum Beispiel die Trommel 8 bei erkannt (wie durch die Messeinrichtung 2) zu hoher Unwucht abgestoppt werden, und damit eine günstigere Verteilung der Wäsche W erreicht werden. Vorliegend soll davon ausgegangen werden, dass die Verteilung der Wäsche zur Reduzierung der Unwucht durch eine zuvor beschriebene Maßnahme schon primär gelöst ist. Dennoch ist es nach wie vor erforderlich die in der Schleuder-Betriebsphase auftretende Schwingung zu dämpfen. Da es schon betreffend des aggregativen Aufwandes ungünstig wäre, neben den Linearmotoren 6 und 6', die örtlich geometrisch die Lage vormalig eingesetzter Dämpfer einnehmen, zusätzliche Dämpfer einsetzen zu müssen, wurde untersucht, ob durch die Steuerung bzw. Regelung der Linearmotore nicht auch eine Dämpferfunktion nachgebildet werden kann.As is well known, the vibratory tub system is excited to oscillate by itself in a spin process by laundry W, which is generally unevenly distributed in the drum. There are numerous approaches to how this imbalance can be reduced by appropriate measures. It can, for example, the
Dabei wurde herausgefunden, dass über die Linearmotore 6 und 6' bei deren geeigneter Ansteuerung, wobei über die Messeinrichtung 2 die gemessene Werte der Auslenkung mittelbar über die Programmsteuerung herangezogen werden, eine aktive Dämpfung der beim Schleudervorgang entstehenden Schwingung des schwingungsfähigen Laugenbehältersystems erzielt werden kann. Damit ist es also möglich, über die steuerbaren Linearmotore 6 und 6', die gegenüber dem Antrieb der Trommel ein weiteres Antriebssystem bilden, nicht nur die Waschperformance zu erhöhen, sondern auch eine wirksame aktive Dämpfung zu erreichen. Hier würde auch ein Ansatz liegen, die beim Schleudervorgang ungewollt entstehende Energie durch Energierückführung (Rekuperation) mittels der Antriebssteuerung 20 in das Versorgungsnetz zu leiten.It was found that via the linear motors 6 and 6 'with their suitable control, whereby the measurement values of deflection are used indirectly via the program control via the
Darüber hinaus ist es auch möglich, zur Erzielung der aktiven Dämpfung beim Schleudervorgang über die Linearmotore 6 und 6' eine lineare Bewegung des Laugenbehältersystems zu bewirken, wobei die lineare Bewegung der von einer Unwucht verursachten Bewegung des Laugenbehältersystems entgegengerichtet ist. In seltenen Ausnahmefällen könnte es erforderlich werden, eine Dämpfereinrichtung mit einem mechanischen Reibdämpfer hinzuzunehmen, die dann jedoch von ihrer Dämpferwirkung her schaltbar ausgelegt sein müssten, da in der eigentlichen Waschphase über die Linearmotore 6 und 6' ausgelöste Schwingung zur Erhöhung der Waschperformance nicht noch gedämpft werden darf.Moreover, it is also possible to effect linear motion of the tub system to achieve the active damping during the spin operation via the linear motors 6 and 6 ', with the linear motion of the movement of the tub system caused by imbalance being counteracted. In rare exceptional cases, it might be necessary to add a damper device with a mechanical friction damper, which would then have to be designed switchable from its damper effect, as in the actual washing phase on the linear motors 6 and 6 ' triggered vibration to increase the washing performance may not be damped.
Im Unterschied zu dem Ausführungsbeispiel nach
Zur Beschreibung der verfahrensmäßigen Lehre wird von einem ersten Antriebssystem für die Drehung der Trommel und von einem weiteren Antriebssystem zur linearen Auslenkung der Trommel gesprochen. Dies soll für beide Ausführungsbeispiele so gelten.To describe the teaching of the method is spoken by a first drive system for the rotation of the drum and of another drive system for linear deflection of the drum. This should be the case for both embodiments.
