Description

Die Erfindung betrifft einen Zyklonabscheider für einen Staubsauger und einen Staubsauger. Staubsauger gemäß dem Oberbegriff von Anspruch 1. Ein derartiger Staubsauger ist aus der US-2,566,153 bekannt. Bei einem Zyklonabscheider kann ein Feinstaubfilter erforderlich sein. Der Feinstaubfilter kann durch Feinstaub zugesetzt werden, was zu einem Saugkraftverlust führen kann.
Der Erfindung stellt sich die Aufgabe, einen verbesserten Zyklonabscheider für einen Staubsauger und einen verbesserten Staubsauger zu schaffen.
Erfindungsgemäß wird diese Aufgabe durch einen Zyklonabscheider für einen Staubsauger sowie einen Staubsauger mit den Merkmalen der Hauptansprüche gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.
Ein Feinstaubfilter kann ausgewaschen, abgerüttelt oder ausgeklopft werden. Wenn der Feinstaubfilter abgerüttelt oder ausgeklopft wird, wird anhaftender Feinstaub aufgrund seiner Massenträgheit aus einem Filtermedium des Feinstaubfilters geschleudert und Poren des Filtermediums werden wieder freigegeben. Der abgerüttelte oder abgeklopfte Feinstaub kann mit gröberem Sauggut entsorgt werden.
Das Ausklopfen des Feinstaubfilters kann durch eine Ausklopfeinrichtung auf einer Luftaustrittsseite des Feinstaubfilters ausgeführt werden. Der anhaftende Feinstaub verbleibt dabei auf einer Lufteintrittsseite des Feinstaubfilters. Die Ausklopfeinrichtung kann eine lokale elastische Verformung des Filtermediums hervorrufen. Wenn das Filtermedium zurückfedert, bewirkt die resultierende ruckartige Beschleunigung das Abklopfen des Feinstaubs.
Die Verformung des Filtermediums kann bei einem zylinderförmigen Feinstaubfilter durch eine Drehbewegung hervorgerufen werden. Die Drehbewegung kann von einem von außen zugänglichen Zyklonbehälter des Zyklonabscheiders auf den Feinstaubfilter übertragen werden.
Bei der hier vorgestellten Lösung zum Reinigen des Feinstaubfilters ist es nicht erforderlich, in den Schmutzbereich zu fassen. Ebenso ist es nicht erforderlich, einen verschmutzten Schaumfilter in die Hand zu nehmen, um diesen auszuwaschen. Der hier vorgestellte Ansatz ist darüber hinaus technisch einfach, da kein Elektromotor und/oder Getriebe erforderlich ist. Das Abreinigen des Feinstaubfilters zwischendurch ist einfach und hygienisch. Der Kontakt mit Schmutz wird vermieden. Die Reinigung ist während des Saugens möglich, ohne das Gerät auseinanderzubauen. Der Saugvorgang wird durch das Reinigen des Feinstaubfilters nicht unterbrochen. Das Abreinigen ist einfach.The invention relates to a cyclone separator for a vacuum cleaner and a vacuum cleaner. Vacuum cleaner according to the preamble of claim 1. Such a vacuum cleaner is from the US 2,566,153 known. In a cyclone separator, a particulate matter filter may be required. The fine dust filter can be added by fine dust, which can lead to a loss of suction power.
The invention has as its object to provide an improved cyclone separator for a vacuum cleaner and an improved vacuum cleaner.
According to the invention this object is achieved by a cyclone separator for a vacuum cleaner and a vacuum cleaner with the features of the main claims. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
A fine dust filter can be washed out, shaken off or knocked out. If the fine dust filter is shaken or knocked out, adhering fine dust is hurled out of a filter medium of the fine dust filter due to its inertia and pores of the filter medium are released again. The shaken or knocked-off fine dust can be disposed of with coarser material.
The knocking out of the fine dust filter can be carried out by a knockout device on an air outlet side of the fine dust filter. The adhering fine dust remains on an air inlet side of the fine dust filter. The knockout device may cause a local elastic deformation of the filter medium. When the filter medium springs back, the resulting jerky acceleration causes the fine dust to knock off.
The deformation of the filter medium can be caused by a rotary movement in a cylindrical particulate filter. The rotary motion can be transmitted from an externally accessible cyclone tank of the cyclone separator to the fine dust filter.
In the solution presented here for cleaning the fine dust filter, it is not necessary to grasp in the dirt area. Likewise, it is not necessary to pick up a soiled foam filter to wash it out. The approach presented here is also technically simple, since no electric motor and / or transmission is required. Cleaning the fine dust filter in between is easy and hygienic. Contact with dirt is avoided. The cleaning is possible while sucking, without that Disassemble device. The suction process is not interrupted by the cleaning of the fine dust filter. Cleaning is easy.

Es wird ein Zyklonabscheider für einen Staubsauger vorgestellt, wobei der Zyklonabscheider die folgenden Merkmale aufweist:

  • einen um ein zentrales Lufteintrittsrohr des Zyklonabscheiders drehbaren, abnehmbaren Zyklonbehälter; und
  • einen um das Lufteintrittsrohr drehbaren und mit dem Lufteintrittsrohr verbundenen Feinstaubfilter, der lösbar mit dem Zyklonbehälter gekoppelt ist.
A cyclone separator for a vacuum cleaner is presented, the cyclone separator having the following features:
  • a removable cyclone container rotatable about a central air inlet tube of the cyclone separator; and
  • a fine dust filter rotatable about the air inlet tube and connected to the air inlet tube, which is releasably coupled to the cyclone container.

Unter einem Zyklonabscheider kann ein Fliehkraftabscheider beziehungsweise eine Abscheideeinrichtung für Feststoffe und/oder Flüssigkeiten aus einem Luftstrom verstanden werden. Im Zyklonabscheider wird der einströmende Luftstrom dazu in Rotation versetzt. Die Rotation kann als Zyklon bezeichnet werden. Durch die Rotation wirkt auf Teilchen im Luftstrom eine Fliehkraft, die die Teilchen an eine Wand des Zyklonabscheiders drängt. Dort werden die Teilchen abgebremst und rieseln aus dem Luftstrom aus. Ein Zyklonbehälter ist im Wesentlichen zylindrisch. Der Zyklonbehälter kann auch leicht konisch sein. Das Lufteintrittsrohr ist zentral entlang einer Hauptachse des Zyklonbehälters angeordnet und an einem oberen Ende des Zyklonabscheiders zu der Wand des Zyklonbehälters gebogen, um den Luftstrom zur Wand zu leiten und in die Rotation zu versetzen. Ein Feinstaubfilter weist eine geringe Porengröße und eine große Oberfläche zum Zurückhalten von Feinstaub aus dem Luftstrom auf. Der Feinstaubfilter ist ebenfalls zylindrisch und konzentrisch zu dem Zyklonbehälter sowie dem Lufteintrittsrohr angeordnet.A cyclone separator can be understood as meaning a centrifugal separator or a separating device for solids and / or liquids from an air stream. In the cyclone separator, the inflowing air flow is set into rotation. The rotation can be called a cyclone. As a result of the rotation, a centrifugal force acts on particles in the air flow, forcing the particles against a wall of the cyclone separator. There, the particles are slowed down and trickle out of the air stream. A cyclone container is substantially cylindrical. The cyclone container can also be slightly conical. The air inlet tube is centrally located along a major axis of the cyclone vessel and bent at an upper end of the cyclone to the wall of the cyclone vessel to direct and direct the flow of air to the wall. A particulate matter filter has a small pore size and a large surface area for retaining particulate matter from the airflow. The fine dust filter is also cylindrical and arranged concentrically to the cyclone container and the air inlet tube.

Der Feinstaubfilter kann Lamellen aufweisen. Zwischen dem Feinstaubfilter und dem Lufteintrittsrohr kann ein Luftaustrittskanal des Zyklonabscheiders ausgebildet sein. Das Lufteintrittsrohr kann in dem Luftaustrittskanal angeordnete Reinigungspaddel zum Abklopfen der Lamellen des Feinstaubfilters aufweisen. Durch Lamellen kann der Feinstaubfilter eine große Oberfläche bereitstellen. Reinigungspaddel können eine Innenseite des Feinstaubfilters berühren. Durch eine Drehbewegung zwischen dem Lufteinlassrohr und dem Feinstaubfilter kann der Feinstaubfilter ausgeklopft werden.The fine dust filter may have lamellae. An air outlet channel of the cyclone separator can be formed between the fine dust filter and the air inlet tube. The air inlet tube may have cleaning paddles arranged in the air outlet channel for tapping the fins of the fine dust filter. Slats allow the fine dust filter to provide a large surface area. Cleaning paddles may touch an inside of the particulate filter. The fine dust filter can be knocked out by a rotary movement between the air inlet tube and the fine dust filter.

Ein unteres Ende des Feinstaubfilters kann an dem Lufteintrittsrohr drehbar gelagert sein, um ein unteres Ende des Luftaustrittskanals auszubilden. Ein oberes Ende des Feinstaubfilters kann an einer Außenseite des Luftaustrittskanals drehbar gelagert sein. Der Feinstaubfilter kann an zwei Lagerstellen drehbar gelagert sein. Die Lagerstellen können die Drehbewegung ermöglichen, jedoch eine axiale Bewegung verhindern. Dadurch ist der Feinstaubfilter fest mit dem Lufteinlassrohr verbunden.A lower end of the particulate matter filter may be rotatably supported on the air inlet tube to form a lower end of the air outlet channel. An upper end of the fine dust filter may be rotatably mounted on an outer side of the air outlet channel. The fine dust filter can be rotatably mounted on two bearings. The bearings can allow rotational movement but prevent axial movement. As a result, the fine dust filter is firmly connected to the air inlet tube.

Der Zyklonbehälter und der Feinstaubfilter können miteinander verzahnt sein. Durch eine Verzahnung kann die Drehbewegung übertragen werden.The cyclone tank and the fine dust filter can be interlocked. By a toothing, the rotational movement can be transmitted.

Der Zyklonbehälter und der Feinstaubfilter können je zumindest einen Zahn und eine Zahnlücke aufweisen. Der Zahn kann eine geringere Breite, als die Zahnlücke aufweisen. Durch schmale Zähne kann ein Zusammenfügen des Zyklonfilters vereinfacht sein.The cyclone container and the fine dust filter can each have at least one tooth and one tooth gap. The tooth may have a smaller width than the tooth gap. Narrow teeth can simplify the joining of the cyclone filter.

Die Zahnlücke kann an zumindest einem Übergang zu einer Zahnflanke eine geringere Tiefe aufweisen, als eine Zahnhöhe des Zahns an dem Übergang. Durch im Randbereich flachere Zahnlücken kann eine axiale Bewegung zwischen dem Feinstaubfilter und dem Zyklonbehälter bewirkt werden. Da der Feinstaubfilter axial unbeweglich ist, wird der Zyklonbehälter um einen geringen Weg von dem Feinstaubfilter weggedrückt. Dieser geringe Weg erleichtert die Drehbewegung des Zyklonbehälters gegen seine Dichtungen.The tooth gap may have a smaller depth at at least one transition to a tooth flank than a tooth height of the tooth at the transition. By shallower tooth gaps in the edge region, an axial movement between the fine dust filter and the cyclone container can be effected. Since the fine dust filter is axially immovable, the cyclone container is pushed away by a small distance from the fine dust filter. This small path facilitates the rotational movement of the cyclone tank against its seals.

Weiterhin wird ein Staubsauger mit einem Zyklonabscheider gemäß dem hier vorgestellten Ansatz vorgestellt.Furthermore, a vacuum cleaner is presented with a cyclone according to the approach presented here.

In der nachfolgenden Beschreibung günstiger Ausführungsbeispiele der vorliegenden Erfindung werden für die in den verschiedenen Figuren dargestellten und ähnlich wirkenden Elemente gleiche oder ähnliche Bezugszeichen verwendet, wobei auf eine wiederholte Beschreibung dieser Elemente verzichtet wird.In the following description of favorable embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and similar acting, with a repeated description of these elements is omitted.

Figur 1 zeigt eine Darstellung eines Staubsaugers 100 gemäß einem Ausführungsbeispiel. Der dargestellte Staubsauger 100 weist oben einen Gerätekorpus 102, in der Mitte einen Zyklonabscheider 104 und unten einen Anschluss 106 für eine Saugdüse auf. Dabei ist der Zyklonabscheider 104 in Verlängerung des Gerätekorpus 102 angeordnet. Der Anschluss 106 ist auf einer dem Gerätekorpus 102 gegenüberliegenden Seite des Zyklonabscheiders 104 angeordnet. Damit ist der Anschluss 106 an einer Unterseite des Staubsaugers 100 angeordnet. An dem Anschluss 106 kann beispielsweise eine Bodendüse angeschlossen werden. Der Zyklonabscheider 104 ist ein Zyklonabscheider mit koaxialen Luftwegen und Lamellen-Feinstaubfilter 108. Im Gerätekorpus 102 sind ein Antrieb und ein Ansauggebläse des Staubsaugers 100 angeordnet. Angesaugte Luft wird von dem Anschluss 106 durch ein zentrales Lufteintrittsrohr 110 nach oben in den Zyklonabscheider 104 gesaugt. An einer dem Gerätekorpus 102 zugewandten Seite des Zyklonabscheiders wird der Luftstrom in Rotation um das Lufteintrittsrohr 110 versetzt und tritt in einen Zyklonbehälter 112 des Zyklonabscheiders 104 ein. Im Zyklonbehälter 112 wird Grobstaub aus dem Luftstrom abgeschieden und setzt sich in einem Sammelbereich 114 an einer vom Gerätekorpus 102 abgewandten Seite des Zyklonbehälters 112 ab. Die Luft wird durch den koaxial zu dem Lufteintrittsrohr 110 angeordneten Feinstaubfilter 108 in ein zum Gerätekorpus 102 und dem Gebläse führendes Luftaustrittsrohr 116 abgesaugt. FIG. 1 shows a representation of a vacuum cleaner 100 according to an embodiment. The illustrated vacuum cleaner 100 has a device body 102 at the top, a cyclone separator 104 in the middle and a connection 106 for a suction nozzle at the bottom. In this case, the cyclone separator 104 is arranged in extension of the device body 102. The connection 106 is arranged on a side of the cyclone separator 104 opposite the device body 102. Thus, the terminal 106 is disposed on an underside of the vacuum cleaner 100. For example, a floor nozzle can be connected to the connection 106. The cyclone separator 104 is a cyclone separator with coaxial air paths and fin particulate filter 108. In the apparatus body 102, a driver and an aspirator of the vacuum cleaner 100 are arranged. Sucked air is drawn from the port 106 up through a central air inlet tube 110 into the cyclone 104. On a side of the cyclone separator facing the apparatus body 102, the air flow is set in rotation about the air inlet pipe 110 and enters a cyclone tank 112 of the cyclone separator 104. In the cyclone container 112, coarse dust is separated from the air stream and settles in a collecting region 114 on a side remote from the device body 102 of the cyclone container 112 from. The air is sucked through the coaxial with the air inlet tube 110 arranged particulate matter filter 108 in a device body 102 and the fan leading air outlet pipe 116.

In Figur 1 ist ein Detailbereich 118 zwischen dem Feinstaubfilter 108 und dem Sammelbereich 114 markiert. Der Detailbereich 118 ist in Figur 2 dargestellt.In FIG. 1 a detail area 118 is marked between the particulate matter filter 108 and the collection area 114. The detail area 118 is in FIG. 2 shown.

Mit anderen Worten zeigt Figur 1 ein Bodenpflegegerät 100 mit einem Lamellenfilter 108 mit innenliegender Abreinigungsmechanik. Zyklonstaubsauger 100 ohne Multizyklonsystem benötigen zusätzlich zum Zyklonabscheider 104 immer auch einen Feinstaubfilter 108 zum Anscheiden kleinster Partikel. Dieser hat die Eigenschaft, mit der Zeit zu verstopfen, was wiederum zu einem Saugkraftverlust des Staubsaugers 100 führt. Um die Reinigungsleistung des Staubsaugers 100 wieder vollständig wiederherzustellen, kann der Filter 108 in regelmäßigen Abständen gereinigt werden. Es gibt verschiedene Ansätze zur Feinstaubfilterreinigung, wie Auswaschen, Rütteln und Klopfen. Das Ausklopfen kann manuell oder automatisch erfolgen.In other words shows FIG. 1 a floor care appliance 100 with a lamellar filter 108 with internal cleaning mechanism. Cyclonic vacuum cleaner 100 without multi-cyclone system In addition to the cyclone separator 104, a particulate filter 108 is always required for the separation of very small particles. This has the property of clogging with time, which in turn leads to a loss of suction of the vacuum cleaner 100. To fully restore the cleaning performance of the vacuum cleaner 100, the filter 108 may be cleaned at regular intervals. There are several approaches to fine dust filter cleaning, such as washing, shaking and tapping. The knocking can be done manually or automatically.

Der Zyklonabscheider 104 mit koaxialen Luftwegen weist zentral den Lamellenfilter 108 auf. Dieser ist um die Längstachse drehbar gelagert und am unteren Ende lösbar an den zylindrischen Zyklonbehälter 112 gekoppelt. Innerhalb des Lamellenfilters 108 befindet sich starr am Gerät angekoppelt der lange Lufteintrittskanal 110 mit seitlich angeformten Paddeln. Durch Drehen des Zyklonbehälters 112 um die Längsachse von außen mit der Hand dreht sich der Lamellenfilter 108 um den innenliegenden Lufteintrittskanal 110, wobei die Paddel über die einzelnen Lamellen streifen und diese dadurch abklopfen. Die mechanische Einwirkung auf den Lamellenfilter 108 bewirkt, dass der festsitzende Feinstaub aus den Poren herausgeschleudert wird und in den Zyklonbehälter 112 fällt. Dieser Feinstaub wird dann mit der nächsten Entleerung entsorgt.The cyclone separator 104 with coaxial airways centrally has the lamellar filter 108. This is rotatably mounted about the longitudinal axis and at the lower end releasably coupled to the cylindrical cyclone container 112. Inside the lamellar filter 108, the long air inlet channel 110 is rigidly coupled to the device with laterally formed paddles. By turning the cyclone container 112 around the longitudinal axis from the outside by hand, the lamellar filter 108 rotates about the inner air inlet channel 110, wherein the paddles strip over the individual lamellae and thereby knock them off. The mechanical action on the lamellar filter 108 causes the stuck particulate matter is ejected from the pores and falls into the cyclone tank 112. This fine dust is then disposed of with the next emptying.

Figur 2 zeigt zwei Detaildarstellungen einer axialen Verzahnung 200 gemäß einem Ausführungsbeispiel. Hier ist jeweils der Detailbereich 118 aus Figur 1 dargestellt. Die Verzahnung 200 besteht aus Zähnen 202, die in Zahnlücken 204 eingreifen. Sowohl der Feinstaubfilter 108 beziehungsweise ein Träger 206 des Feinstaubfilters 108, als auch der Zyklonbehälter 112 weisen dabei gleichartige Zähne 202 und Zahnlücken 204 auf. Dabei sind die Zahnlücken 204 breiter, als die Zähne 202. Die Zähne 202 sind also in den Zahnlücken 204 seitlich beweglich. Die Verzahnung 200 ist trennbar. Der Träger 206 ist um einen, durch die Breite der Zahnlücken 204 definierten Winkel relativ zu dem Zyklonbehälter 112 verdrehbar, bevor die Zahnflanken von zwei Zähnen aneinander anliegen. FIG. 2 shows two detailed views of an axial toothing 200 according to an embodiment. Here is the detail area 118 from FIG. 1 shown. The toothing 200 consists of teeth 202 which engage in tooth gaps 204. Both the fine dust filter 108 and a carrier 206 of the particulate matter filter 108, as well as the cyclone container 112 in this case have similar teeth 202 and tooth spaces 204. The tooth gaps 204 are wider than the teeth 202. The teeth 202 are thus laterally movable in the tooth spaces 204. The toothing 200 is separable. The carrier 206 is rotatable about an angle defined by the width of the tooth gaps 204 relative to the cyclone container 112 before the tooth flanks of two teeth abut each other.

Die Zahnlücken 204 weisen im Bereich der Zahnflanken eine geringere Tiefe auf, als in einer Mitte der Zahnlücken 204.The tooth gaps 204 have a smaller depth in the region of the tooth flanks than in a middle of the tooth gaps 204.

In der ersten Detaildarstellung sind die Zähne 202 mittig in den Zahnlücken 204 angeordnet. Die Verzahnung weist so eine minimale Höhe auf.In the first detailed illustration, the teeth 202 are arranged centrally in the tooth spaces 204. The teeth thus has a minimum height.

In der zweiten Detaildarstellung ist der Träger 206 zu einer verdreht, bis die Zahnflanken aneinander anliegen. Dadurch sind die Zähne 202 über eine Schräge Ebene in den erhöhten Bereich gerutscht. Die Verzahnung 200 weist jetzt eine größere Höhe auf, als in der ersten Detaildarstellung.In the second detail view, the carrier 206 is turned to one until the tooth flanks abut each other. As a result, the teeth 202 have slid over a slanted plane in the raised area. The toothing 200 now has a greater height than in the first detailed representation.

Mit anderen Worten werden der Träger 206 mit dem Feinstaubfilter 208 und der Zyklonbehälter 112 axial geringfügig auseinander gedrückt, wenn der Zyklonbehälter 112 gegenüber dem Träger 206 verdreht wird.In other words, the carrier 206 with the particulate filter 208 and the cyclone container 112 are axially slightly apart when the cyclone container 112 is rotated relative to the carrier 206.

Figur 3 zeigt eine Darstellung eines Lösens eines Zyklonbehälters 112 von einem Zyklonabscheider 104 gemäß einem Ausführungsbeispiel. Der Zyklonabscheider 104 entspricht im Wesentlichen dem Zyklonabscheider in Figur 1. Hier ist der Zyklonbehälter 112 wie in der zweiten Detaildarstellung in Figur 2 geringfügig gegenüber dem Träger 206 verdreht. Dadurch werden Dichtungen 300 des Zyklonbehälters 112 geringfügig auseinander gedrückt, was ein Drehen des Zyklonbehälters 112 mit dem daran gekoppelten Feinstaubfilter 108 gegenüber dem Lufteintrittsrohr 110 aufgrund einer verringerten Reibung erleichtert. FIG. 3 FIG. 3 shows a representation of a release of a cyclone container 112 from a cyclone separator 104 according to one embodiment. The cyclone 104 substantially corresponds to the cyclone separator in FIG FIG. 1 , Here, the cyclone container 112 is as in the second detail illustration in FIG FIG. 2 slightly twisted relative to the carrier 206. As a result, gaskets 300 of the cyclone tank 112 are pushed slightly apart, which facilitates rotation of the cyclone tank 112 with the particulate matter filter 108 coupled thereto against the air inlet pipe 110 due to reduced friction.

Die Kopplung des Lamellenfilters 108 ist dabei so ausgelegt, dass durch die Drehung der feststehende Teil des Abscheiders 104 leicht angehoben wird. Dadurch werden die pressenden Dichtungen 300 gelockert und eine leichtere Drehung mit der Hand ermöglicht.The coupling of the lamellar filter 108 is designed so that is slightly lifted by the rotation of the fixed part of the separator 104. As a result, the pressing seals 300 are loosened and allow easier rotation by hand.

Figur 4 zeigt eine Darstellung eines von einem Zyklonabscheider 104 getrennten Zyklonbehälters 112 gemäß einem Ausführungsbeispiel. Der Zyklonabscheider 104 entspricht im Wesentlichen dem Zyklonabscheider in den Figuren 1 bis 3. Zum Entleeren des Sammelbereichs 114 wird der Feinstaubfilter 108, der drehbar an dem Lufteintrittsrohr 110 gelagert ist, mit seinem Träger 206, dem Lufteintrittsrohr 110 und dem Luftaustrittsrohr 116 axial aus dem Zyklonbehälter 112 entnommen. Dabei wird die Verzahnung 200 gelöst. FIG. 4 shows a representation of a cyclone separated from a cyclone separator 104 cyclone container 112 according to one embodiment. The cyclone separator 104 substantially corresponds to the cyclone separator in FIGS FIGS. 1 to 3 , To empty the collecting area 114, the fine dust filter 108, which is rotatably mounted on the air inlet tube 110, with its carrier 206, the air inlet tube 110 and the air outlet pipe 116 axially removed from the cyclone 112. In this case, the toothing 200 is released.

Figur 5 zeigt eine Schnittdarstellung durch einen Zyklonabscheider 104 gemäß einem Ausführungsbeispiel. Der Zyklonabscheider 104 entspricht im Wesentlichen dem Zyklonabscheider in den Figuren 1 bis 4. Der Zyklonabscheider 104 ist im Wesentlichen rotationssymmetrisch. Nur das Lufteintrittsrohr 110 weist im oberen Teil eine asymmetrische Luftführung auf, um den angesaugten Luftstrom in Rotation zu versetzen. Das Lufteintrittsrohr 110 umhüllt einen Lufteintrittskanal 500 des Zyklonabscheiders 104. Am oberen Ende des Zyklonabscheiders 104 tritt in dem Luftaustrittsrohr 116 ein Luftaustrittskanal 502 koaxial zu dem Lufteintrittskanal 500 aus dem Zyklonabscheider 104 aus. FIG. 5 shows a sectional view through a cyclone 104 according to an embodiment. The cyclone separator 104 substantially corresponds to the cyclone separator in FIGS FIGS. 1 to 4 , The cyclone 104 is substantially rotationally symmetric. Only the air inlet tube 110 has in the upper part of an asymmetric air duct to enable the sucked air flow in rotation. The air inlet tube 110 encloses an air inlet channel 500 of the cyclone separator 104. At the upper end of the cyclone separator 104, an air outlet channel 502 exits the cyclone separator 104 coaxially with the air inlet channel 500 in the air outlet tube 116.

Auf einer Außenseite des Lufteintrittsrohrs 110 sind im Luftaustrittskanal 502 Reinigungspaddel 504 angeordnet. Die Reinigungspaddel 504 sind länger als eine Dicke des Luftaustrittskanals 502 in dem Bereich. Dadurch berühren die Reinigungspaddel 504 die Lamellen des Feinstaubfilters 108, um bei einer relativen Drehbewegung des Lufteintrittsrohrs 110 und des Feinstaubfilters 108 am Feinstaubfilter 108 anhaftenden Feinstaub abzuschlagen. Um die Drehbewegung von dem außen liegenden Zyklonbehälter 112 auf den innenliegenden Feinstaubfilter 108 zu übertragen, ist der Träger 206 mit dem Zyklonbehälter 112 über eine Kupplung 200 wie in Fig. 2 verzahnt. Das Lufteintrittsrohr 110 steckt dabei in einem den Sammelbereich 114 ausbildenden Rohrstumpf des Zyklonbehälters 112. Das Ende des Rohrstumpfs ist verzahnt.On an outer side of the air inlet tube 110 502 cleaning paddle 504 are arranged in the air outlet channel. The cleaning paddles 504 are longer than a thickness of the air outlet channel 502 in the area. As a result, the cleaning paddles 504 touch the fins of the fine dust filter 108 in order to cut off fine dust adhering to the fine dust filter 108 when the air inlet tube 110 and the fine dust filter 108 rotate relative to one another. In order to transfer the rotational movement from the outer cyclone container 112 to the inner particulate filter 108, the carrier 206 is connected to the cyclone container 112 via a coupling 200 as in FIG Fig. 2 toothed. The air inlet tube 110 is inserted in a tube stump of the cyclone container 112 forming the collecting region 114. The end of the tube stub is toothed.

Der Träger 206 weist zwei Lagerstellen 506 auf. Die Lagerstellen 506 ermöglichen eine Rotationsbewegung des Feinstaubfilters 108 und des Trägers 206 um das Lufteintrittsrohr 110. Die Lagerstellen 506 fixieren den Träger 206 und den Feinstaubfilter 108 in axialer Richtung am Lufteintrittsrohr 110 und am Luftaustrittsrohr 116. An einem unteren Ende des Trägers 206 ist der Träger über eine der Lagerstellen 506 direkt am Lufteintrittsrohr 110 abgestützt. An einem oberen Ende ist der Träger 206 an dem Luftaustrittsrohr 116 abgestützt.The carrier 206 has two bearings 506. The bearings 506 allow rotational movement of the particulate matter filter 108 and the carrier 206 about the air inlet tube 110. The bearings 506 fix the carrier 206 and the particulate filter 108 in the axial direction of the air inlet tube 110 and the air outlet tube 116. At a lower end of the carrier 206 is the carrier supported by one of the bearings 506 directly on the air inlet tube 110. At an upper end of the carrier 206 is supported on the air outlet pipe 116.

Der Sammelbereich 114 ist unterhalb einer quer zu dem Lufteintrittsrohr 110 ausgerichteten Platte angeordnet. Die Platte ist durch einen Spalt von einer Innenseite des Zyklonbehälters 112 beabstandet. Grobe Partikel fallen durch den Spalt in den Sammelbereich 114. Die Platte bildet ein unteres Ende des Luftaustrittsrohrs 116 aus.The collecting area 114 is arranged below a plate aligned transversely to the air inlet tube 110. The plate is spaced from the inside of the cyclone container 112 by a gap. Coarse particles fall through the gap into the collecting area 114. The plate forms a lower end of the air outlet pipe 116.
