The suction material container can be detached from the device body via a rotary movement of the suction material container relative to the device body. Due to the size and weight of the suction material container and the body of the device, such a removal of the suction material container is disadvantageous from the point of view of operator ergonomics.

Der Erfindung stellt sich somit das Problem, einen handgeführten Zyklon-Staubsauger bereitzustellen, bei dem die Entnahme und Bedienung des Sauggutbehälters einfach sind.The invention therefore addresses the problem of providing a hand-held cyclone vacuum cleaner in which the removal and operation of the suction material container are simple.

Erfindungsgemäß wird dieses Problem durch einen handgeführten Zyklon-Staubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a hand-held cyclone vacuum cleaner with the features of claim 1. Advantageous refinements and developments of the invention result from the following dependent claims.

Die mit der Erfindung erreichbaren Vorteile bestehen neben einer einfachen Handhabbarkeit des Sauggutbehälters des Staubsaugers darin, dass die Entnahme und Entleerung mittels eines einzigen Bedienelements durchführbar sind. Dadurch wird dem Nutzer ermöglicht, alle relevanten Handhabungsschritte über ein intuitiv zu bedienendes Drehelement durchzuführen. Das drehbare Bedienelement ist gut in ein Design des Staubsaugers integrierbar, wobei eine gestalterische Freiheit erzielt wird.The advantages that can be achieved with the invention are, in addition to simple handling of the suction material container of the vacuum cleaner, that removal and emptying can be carried out using a single operating element. This enables the user to carry out all relevant handling steps via an intuitively operated rotary element. The rotatable operating element can be easily integrated into the design of the vacuum cleaner, with creative freedom being achieved.

Die Erfindung betrifft einen handgeführten Zyklon-Staubsauger, aufweisend einen Gerätekorpus, der ein Antriebsaggregat aufweist, das ausgebildet ist, einen Saugluftstrom zu erzeugen, einen Sauggutbehälter zur Aufnahme von Sauggut, der mit dem Gerätekorpus verbunden ist, ein Bedienelement, das an einem Ende des Sauggutbehälters angeordnet ist, das dem Ende des Sauggutbehälters gegenüberliegt, an dem der Gerätekorpus angeordnet ist, wobei das Bedienelement von einer ersten Stellung in eine zweite Stellung und umgekehrt drehbar ist, wobei der Gerätekorpus in der ersten Stellung mit dem Sauggutbehälter untrennbar verbunden ist und der Gerätekorpus mit dem Sauggutbehälter in der zweiten Stellung trennbar verbunden ist.The invention relates to a hand-held cyclone vacuum cleaner, having an appliance body which has a drive unit which is designed to generate a suction air flow, a suction material container for receiving suction material, which is connected to the device body, a control element which is located at one end of the suction material container is arranged, which is opposite the end of the suction material container on which the device body is arranged, wherein the control element moves from a first position to a second position and is reversely rotatable, wherein the device body is inseparably connected to the suction material container in the first position and the device body is separably connected to the suction material container in the second position.

Unter dem Ausdruck "handgeführt" ist zu verstehen, dass der Staubsauger per Hand von dem Nutzer bei Betrieb geführt wird. Dazu weist der Staubsauger bevorzugt weiterhin einen Handgriff auf, der mit dem Sauggutbehälter verbindbar ist und bei Betrieb mit ihm verbunden ist. Weiterhin kann der Staubsauger ein Saugrohr aufweisen, das mit dem Sauggutbehälter und/oder dem Gerätekorpus verbindbar ist und bei Betrieb, wenn erforderlich mit einem von ihnen verbunden ist.The term "hand-held" means that the vacuum cleaner is operated manually by the user. For this purpose, the vacuum cleaner preferably also has a handle which can be connected to the suction material container and is connected to it during operation. Furthermore, the vacuum cleaner can have a suction pipe, which can be connected to the suction material container and/or the device body and, if necessary, is connected to one of them during operation.

Unter dem Begriff "Zyklon-Staubsauger" ist ein Staubsauger zu verstehen, der beutellos ist und bei dem in einem in den Staubsauger eintretenden Luftstrom Wirbel und etwaige Verwirbelungen erzeugt werden, wodurch das Sauggut wie z.B. Staubteilchen aufgrund von Fliehkraft in eine vorbestimmte Richtung gedrückt und abgeschieden werden. Unter dem Ausdruck "beutellos" ist zu verstehen, dass das Sauggut in dem Staubsauger direkt im Sauggutbehälter gesammelt wird, ohne dass in diesem ein Beutel oder ein ähnliches Wechselfiltermedium zur Aufnahme von Sauggut angeordnet ist, so dass der Nutzer zur Entleerung des Saugguts aus dem Sauggutbehälter keinen Beutel oder dgl. aus dem Sauggutbehälter entnimmt. Der Staubsauger kann aber ein oder mehrere Filtermedien aufweisen, die verhindern, dass aufgesaugtes Sauggut in das in dem Gerätekorpus angeordneten Antriebsaggregat gelangt. Sowohl der Sauggutbehälter als auch der Gerätekorpus sind bevorzugt aus Kunststoff gebildet.The term "cyclone vacuum cleaner" means a vacuum cleaner that is bagless and in which eddies and any eddies are generated in an air flow entering the vacuum cleaner, whereby the suction material such as dust particles is pressed in a predetermined direction due to centrifugal force and separated become. The term "bagless" means that the suction material in the vacuum cleaner is collected directly in the suction material container, without a bag or a similar exchangeable filter medium for receiving suction material being arranged in it, so that the user can empty the suction material from the suction material container does not remove a bag or the like from the suction material container. However, the vacuum cleaner can have one or more filter media which prevent the vacuumed material from getting into the drive unit arranged in the device body. Both the suction material container and the device body are preferably made of plastic.

Der Staubsauger ist bevorzugt ein Akkustaubsauger. D.h., der Staubsauger weist einen Akkumulator auf und ist ausgelegt, mittels des Akkumulators als Stromquelle betrieben zu werden. Der Akkumulator ist mit dem Sauggutbehälter und/oder dem Gerätekorpus bevorzugt dem Gerätekorpus verbindbar.The vacuum cleaner is preferably a cordless vacuum cleaner. That is, the vacuum cleaner has an accumulator and is designed to be operated using the accumulator as a power source. The accumulator can be connected to the suction material container and/or the device body, preferably the device body.

Der Sauggutbehälter ist bevorzugt formschlüssig am Gerätekorpus geführt. Dadurch wird sichergestellt, dass er sich nicht beim Drehen des Bedienelements am Gerätekorpus verdreht. Das Bedienelement ist in den Sauggutbehälter bevorzugt integriert. Bevorzugt sind der Sauggutbehälter und der Gerätekorpus derart ausgebildet, dass sie nur in der zweiten Stellung trennbar sind; d.h. sie sind in einer anderen als der zweiten Stellung nicht trennbar, wenn sie verbunden sein sollten.The suction material container is preferably guided in a form-fitting manner on the device body. This ensures that it does not twist when turning the control element on the device body. The operating element is preferably integrated into the suction material container. The suction material container and the device body are preferably designed in such a way that they can only be separated in the second position; i.e. they are not separable in any position other than the second when they should be connected.

Unter dem Ausdruck "untrennbar verbunden" ist zu verstehen, dass der Sauggutbehälter und der Gerätekorpus nicht durch ein Auseinanderziehen trennbar sind. Unter dem Ausdruck "trennbar verbunden" ist zu verstehen, der Sauggutbehälter und der Gerätekorpus durch ein Auseinanderziehen trennbar sind.The term "inseparably connected" is to be understood as meaning that the suction material container and the device body cannot be separated by pulling them apart. The term "removably connected" is to be understood as meaning that the suction material container and the device body can be separated by pulling them apart.

In einer betriebsgemäßen Arbeitsposition befindet sich der Sauggutbehälter an einer Rückseite bzw. hinterem Ende des Staubsaugers, womit gemeint ist, dass er ist näher an der Hand des Nutzers und weiter von dem zu saugenden Untergrund entfernt ist als der Gerätekorpus. Dadurch ist das Bedienelement leicht handhabbar.In an operational working position, the suction material container is located at a rear or rear end of the vacuum cleaner, which means that it is closer to the user's hand and further away from the surface to be vacuumed than the device body. As a result, the control element is easy to handle.

In einer bevorzugten Ausführungsform weist der Gerätekorpus eine Basisplatte und einen sich von der Basisplatte weg erstreckenden Stutzen mit einer Rastnocke auf und weist der Sauggutbehälter einen Vorfilter mit einer Verriegelungsgeometrie auf, die derart ausgebildet ist, dass sie die Rastnocke in der ersten Stellung des Bedienelements festhält und in der zweiten Stellung des Bedienelements frei gibt, so dass der Gerätekorpus in der ersten Stellung des Bedienelements mit dem Sauggutbehälter unabziehbar verbunden ist und in der zweiten Stellung mit dem Sauggutbehälter von diesem abziehbar verbunden ist.In a preferred embodiment, the device body has a base plate and a connecting piece with a locking cam that extends away from the base plate, and the suction material container has a prefilter with a locking geometry that is designed in such a way that it holds the locking cam in the first position of the operating element and releases in the second position of the control element, so that the device body is permanently connected to the suction material container in the first position of the control element and is connected to the suction material container in a removable manner in the second position.

In einer bevorzugten Ausführungsform weist der Sauggutbehälter ein Gehäuse und einen Vorfilter mit einem hülsenartigen Teil auf, der in dem Gehäuse angeordnet ist, wobei ein Ende des Gehäuse und ein Ende einer sich von der Basisplatte weg erstreckenden Wand des Gerätekorpus eine komplementäre Kontur aufweisen und der hülsenartige Teil auf den Stutzen aufsetzbar ist. Dadurch sind der Sauggutbehälter und der Gerätekorpus miteinander verbindbar.In a preferred embodiment, the suction material container has a housing and a pre-filter with a sleeve-like part which is arranged in the housing, one end of the housing and one end of a wall of the device body extending away from the base plate having a complementary contour and the sleeve-like part Part can be placed on the nozzle. As a result, the suction material container and the device body can be connected to one another.

Bevorzugt weist der Stutzen mehrere Rastnocken auf und weist der Vorfilter mehrere Verriegelungsgeometrien auf, die jeweils ausgebildet und ausgelegt sind, jeweils eine Rastnocke aufzunehmen, wobei jede Verriegelungsgeometrie einen Schlitz, der beim Aufsetzen des Sauggutbehälters auf den Gerätekorpus in Richtung der Basisplatte hin offen ist, sowie jeweils einen sich von dem jeweiligen Schlitz weg erstreckenden Verriegelungsteil aufweist, der in Richtung der Basisplatte hin geschlossen ist und sich winklig von dem jeweiligen Schlitz in die zu der Basisplatte entgegengesetzte Richtung weg erstreckt. Bevorzugt sind die Rastnocken um den Umfang des Stutzens gleichmäßig verteilt, und bevorzugt sind die Verriegelungsgeometrien um den Umfang des hülsenartigen Teils des Vorfilters gleichmäßig verteilt.The connecting piece preferably has a plurality of locking cams and the pre-filter has a plurality of locking geometries, each of which is designed and designed to accommodate a locking cam, each locking geometry having a slot which is open in the direction of the base plate when the suction material container is placed on the device body, and each having a locking portion extending away from the respective slot, closed towards the base plate and extending angularly away from the respective slot in the direction opposite to the base plate. The locking cams are preferably evenly distributed around the circumference of the connecting piece, and the locking geometries are preferably evenly distributed around the circumference of the sleeve-like part of the prefilter.

Jeder Schlitz jeder Verriegelungsgeometrie ist bevorzugt ausgebildet, eine Rastnocke des Stutzens beim Aufsetzen des Sauggutbehälters auf den Gerätekorpus zumindest teilweise in den hülsenartigen Teil des Vorfilters einführen zu lassen. Dadurch kann das Aufsetzen des Sauggutbehälters auf den Gerätekorpus ohne zusätzliche Krafteinwirkung erfolgen. Der Weg für das Aufsetzen ist limitiert durch einen Anschlag des jeweiligen Schlitzes. Jede Verriegelungsgeometrie weist bevorzugt eine derartige Geometrie auf, dass der Sauggutbehälter in einer vorgegebenen Position aufsetzbar ist. Dadurch ist das System kodiert.Each slot of each locking geometry is preferably designed to allow a locking cam of the connecting piece to be inserted at least partially into the sleeve-like part of the pre-filter when the suction material container is placed on the device body. As a result, the suction material container can be placed on the device body without additional force being applied. The way for the placement is limited by a stop of the respective slot. Each locking geometry preferably has a geometry such that the suction material container can be placed in a predetermined position. This encodes the system.

Bevorzugt sind die Rastnocken und die Verriegelungsgeometrien derart ausgelegt, dass die Rastnocken in dem jeweilig zugeordneten Verriegelungsteil angeordnet sind, wenn sich das Bedienelement in der ersten Stellung befindet und dass die Rastnocken in dem jeweilig zugeordneten Schlitz angeordnet sind, wenn sich das Bedienelement in der zweiten Stellung befindet. Die Rastnocken sind bevorzugt derart ausgelegt, dass sie durch Drehen des Bedienelements in die Schlitze bzw. Verriegelungsteile geführt werden, wenn das Bedienelement von der ersten in die zweite Stellung gedreht wird und umgekehrt. Dadurch sind der Gerätekorpus und der Sauggutbehälter in der ersten Stellung nicht durch Auseinander- bzw. Voneinanderwegziehen trennbar und in der zweiten Stellung durch Auseinanderziehen trennbar. In einer bevorzugten Ausführungsform sind die Schlitze schraubenförmig angeordnet, wodurch der Sauggutbehälter beim Bewegen des Bedienelementes in eine zweite Stellung leicht vom Gerätekorpus abgehoben wird.The locking cams and the locking geometries are preferably designed in such a way that the locking cams are arranged in the respectively assigned locking part when the operating element is in the first position and that the locking cams are arranged in the respectively assigned slot when the operating element is in the second position located. The latching cams are preferably designed in such a way that they are guided into the slots or locking parts by rotating the operating element when the operating element is rotated from the first to the second position and vice versa. As a result, the body of the device and the suction material container cannot be separated in the first position by being pulled apart or pulled away from one another, and can be separated in the second position by being pulled apart. In a preferred embodiment, the slits are arranged in a helical shape, as a result of which the suction material container is lifted off the device body slightly when the operating element is moved into a second position.

Bevorzugt weist der Sauggutbehälter das Gehäuse, den in dem Gehäuse angeordneten Vorfilter, einen in dem Vorfilter angeordneten Zentralfilter und eine Klappe auf, die an dem Ende des Sauggutbehälters angeordnet ist, an dem der Gerätekorpus angeordnet ist. Bevorzugt ist das Bedienelement weiterhin in eine dritte, vierte und/oder fünfte Stellung und umgekehrt drehbar, wobei die Klappe in der dritten Stellung öffenbar ist, der Zentralfilter in der vierten Stellung aus dem Vorfilter und damit aus dem Gehäuse entnehmbar ist und der Vorfilter in der fünften Stellung aus dem Gehäuse entnehmbar ist. Dadurch sind die Entnahme, Entleerung und Service weiterhin mittels eines einzigen Bedienelements durchführbar.The suction material container preferably has the housing, the pre-filter arranged in the housing, a central filter arranged in the pre-filter and a flap which is arranged at the end of the suction material container on which the device body is arranged. Preferably, the operating element can also be rotated into a third, fourth and/or fifth position and vice versa, with the flap being openable in the third position, the central filter being removable from the pre-filter and thus the housing in the fourth position, and the pre-filter being in the fifth position can be removed from the housing. As a result, removal, emptying and service can still be carried out using a single operating element.

Bevorzugt ist das Bedienelement ausgebildet, in die dritte, vierte und fünfte Stellung und umgekehrt drehbar zu sein. Bevorzugt ist das Bedienelement derart ausgebildet, dass es von der ersten in die zweite, von der zweiten in die dritte, von der dritten in die vierte und von der vierten in die fünfte Stellung drehbar ist und umgekehrt.The operating element is preferably designed to be rotatable into the third, fourth and fifth position and vice versa. The operating element is preferably designed in such a way that it can be rotated from the first to the second, from the second to the third, from the third to the fourth and from the fourth to the fifth position and vice versa.

Bevorzugt ist die Klappe nur in der dritten Stellung öffenbar; d.h. sie ist in einer anderen als der dritten Stellung nicht öffenbar ausgebildet. Bevorzugt ist der Zentralfilter nur in der vierten Stellung aus dem Vorfilter entnehmbar; d.h. er ist in einer anderen als der vierten Stellung nicht aus dem Vorfilter entnehmbar ausgebildet. Bevorzugt ist der Vorfilter nur in der fünften Stellung aus dem Gehäuse entnehmbar; d.h., er ist in einer anderen als der fünften Stellung nicht aus dem Gehäuse entnehmbar ausgebildet.The flap can preferably only be opened in the third position; i.e. it is not designed to be openable in a position other than the third position. The central filter can preferably only be removed from the pre-filter in the fourth position; i.e. it is not designed to be removable from the pre-filter in any position other than the fourth position. The pre-filter can preferably only be removed from the housing in the fifth position; that is, it is non-removable from the housing in any position other than the fifth position.

Bevorzugt ist der Sauggutbehälter derart ausgelegt, dass der Nutzer unverschmutzte Bereiche des Zentralfilters und des Vorfilters anfasst, um den Zentralfilter und/oder den Vorfilter zu entnehmen. Dies wird dadurch realisiert, dass vom Nutzer zum Entnehmen zu greifende Bereich des Zentral- und Vorfilters bevorzugt nicht in einem Abscheideraum angeordnet sind, in dem sich Partikel aus einem Saugstrom bei Betrieb abscheiden. D.h., sie befinden sich nicht in einem Sauggutsammelraum, in dem das Sauggut bei Betrieb gesammelt wird.The suction material container is preferably designed in such a way that the user touches unpolluted areas of the central filter and the pre-filter in order to remove the central filter and/or the pre-filter. This is achieved by the fact that the area of the central and pre-filter that the user has to grip for removal is preferably not arranged in a separation space in which particles from a suction flow are separated during operation. Ie, her are not located in a suction material collection chamber in which the suction material is collected during operation.

Bevorzugt ist die Rastnocke des Stutzens in der zweiten Stellung angrenzend zu einem Anschlag der Verriegelungsgeometrie angeordnet, so dass bei einer Drehung des Bedienelements von der ersten Stellung in die zweite Stellung ein weiteres Drehen des Bedienelements über die zweite Stellung hinaus in die dritte Stellung unterbunden wird, solange der Sauggutbehälter auf dem Gerätekorpus angeordnet ist. Dadurch wird sichergestellt, dass die Klappe erst öffenbar ist, wenn der Gerätekorpus von dem Sauggutbehälter getrennt ist.In the second position, the latching cam of the connecting piece is preferably arranged adjacent to a stop of the locking geometry, so that when the operating element is rotated from the first position into the second position, further rotation of the operating element beyond the second position into the third position is prevented, as long as the suction material container is placed on the device body. This ensures that the flap can only be opened when the device body is separated from the suction material container.

In einer bevorzugten Ausführungsform weist die Klappe eine Klappen-Rastnocke auf, die in die Verriegelungsgeometrien des Vorfilters in der zweiten Stellung des Bedienelements eingreift, und die derart ausgebildet ist, dass sie bei einem von dem Gerätekorpus getrennten Sauggutbehälter und einem Drehen des Bedienelements in die dritte Stellung über einer Aussparung in der Verriegelungsgeometrie des Vorfilters liegt, so dass die Klappe öffenbar ist. Dadurch wird sichergestellt, dass die Klappe bei Betrieb des Staubsaugers dicht mit dem Vorfilter verbunden ist. Bevorzugt ist die Klappe durch Schwenken oder Klappen öffenbar. Bevorzugt weist die Klappe mehrere Klappen-Rastnocken auf, die jeweils in eine der mehreren Verriegelungsgeometrien des Vorfilters in der zweiten Stellung des Bedienelements eingreifen. Bevorzugt sind die Klappen-Rastnocken gleichmäßig um einen Umfang der Klappe verteilt angeordnet. Bevorzugt sind die Klappen-Rastnocken zentrisch an der Klappe angeordnet. Dadurch, dass eine Arretierung der Klappe zentrisch und um den Umfang verteilt ausgebildet ist, wird eine weiterhin optimierte Anpressung der Klappe an den Vorfilter und das Gehäuse bereitgestellt.In a preferred embodiment, the flap has a flap latching cam, which engages in the locking geometry of the prefilter when the control element is in the second position, and which is designed in such a way that when the suction material container is separated from the device body and the control element is rotated into the third Position is above a recess in the locking geometry of the pre-filter, so that the flap can be opened. This ensures that the flap is tightly connected to the pre-filter when the vacuum cleaner is in operation. The flap can preferably be opened by pivoting or flaps. The flap preferably has a plurality of flap latching cams, each of which engages in one of the plurality of locking geometries of the prefilter when the operating element is in the second position. The flap locking cams are preferably distributed evenly around the circumference of the flap. The flap locking cams are preferably arranged centrally on the flap. Due to the fact that a locking of the flap is designed centrally and distributed around the circumference, a further optimized pressing of the flap onto the pre-filter and the housing is provided.

Bevorzugt weist der Sauggutbehälter weiterhin eine Feder auf, die ausgebildet ist, die Klappe in der dritten Stellung des Bedienelements von dem Gehäuse und dem Vorfilter weg zu schwenken. Dadurch wird ein Öffnen der Klappe zum Entleeren des Sauggutbehälters automatisiert. Die Feder ist bevorzugt mit dem Vorfilter und der Klappe verbunden. Bevorzugt ist die Feder mit dem Vorfilter über einen Faltenbalg verbunden, der weiterhin eine Bewegung eines mittels einer Trennplatte gebildeten Abluftkanals in Richtung aus dem Sauggutbehälter beim Öffnen der Klappe unterstützt, wobei die Trennplatte, den Abluftkanal von dem Sauggutsammelraum in einer radialen Richtung trennt.The suction material container preferably also has a spring which is designed to pivot the flap away from the housing and the pre-filter when the operating element is in the third position. This automates opening of the flap for emptying the suction material container. The spring is preferably connected to the pre-filter and the flap. The spring is preferably connected to the pre-filter via a bellows, which also supports a movement of an exhaust air duct formed by means of a separating plate in the direction out of the suction material container when the flap is opened, the separating plate separating the exhaust air duct from the suction material collecting chamber in a radial direction.

In einer bevorzugten Ausführungsform weist der Sauggutbehälter weiterhin einen Rasthaken auf, der am Vorfilter angeordnet ist, der den Zentralfilter in dem Vorfilter hält und der derart ausgebildet ist, dass er in einem Betriebszustand kraftfrei ist und nach einem Drehen des Bedienelements in die vierte Stellung einem Federweg freigegeben ist, so dass der Zentralfilter aus dem Vorfilter entnehmbar ist. Dadurch ist sichergestellt, dass der Zentralfilter aus dem Vorfilter bei Bedarf beispielsweise zum Reinigen entnehmbar ist, aber ansonsten mit dem Vorfilter fest verbunden ist.In a preferred embodiment, the suction material container also has a latching hook, which is arranged on the pre-filter, which holds the central filter in the pre-filter and which is designed in such a way that it is force-free in an operating state and has a spring travel after turning the control element into the fourth position is released, so that the central filter can be removed from the pre-filter. This ensures that the central filter can be removed from the pre-filter if required, for example for cleaning, but is otherwise firmly connected to the pre-filter.

Bevorzugt weist der Vorfilter mindestens drei Kreuzrippen auf und weist das Bedienelement einen Zentrierring mit Nuten auf, in denen die Kreuzrippen laufen. Bevorzugt sind die Nuten derart ausgebildet, dass sie in der fünften Stellung jeweils eine Öffnung aufweisen, so dass der Vorfilter und das Bedienelement senkrecht zur Drehachse des Bedienelements entnommen werden können. Bevorzugt sind die Nuten derart ausgebildet, dass sich bei einer Bewegung des Vorfilters zwischen der dritten und fünften Position der Vorfilter vom Zentralfilter abhebt. Dadurch kann in einem Servicefall ein optimaler Zugang zu allen Bauteilen gewährleistet werden. Die Kreuzrippen sind bevorzugt über den Umfang des Vorfilters verteilt angeordnet. Sie dienen als Führungselemente bei einem Drehvorgang des Bedienelements. In einer alternativen Ausführungsform weist der Vorfilter mindestens drei Zapfen und das Bedienelement einen Zentrierring mit Nuten auf, in denen die Zapfen laufen. Wenn der Zentralfilter in der fünften Stellung des Bedienelements in dem Vorfilter angeordnet ist, ist er zusammen mit diesem und dem Bedienelement in der fünften Stellung entnehmbar. Der Zentralfilter kann aber auch schon in der vierten Stellung des Bedienelements aus dem Vorfilter entnommen worden sein. Es ist in der fünften Stellung unerheblich, ob der Zentralfilter sich in dem Vorfilter befindet oder nicht.The pre-filter preferably has at least three cross ribs and the operating element has a centering ring with grooves in which the cross ribs run. The grooves are preferably designed in such a way that they each have an opening in the fifth position, so that the pre-filter and the operating element can be removed perpendicular to the axis of rotation of the operating element. The grooves are preferably designed in such a way that when the pre-filter moves between the third and fifth position, the pre-filter is lifted off the central filter. This ensures optimal access to all components in the event of service. The crossed ribs are preferably distributed over the circumference of the pre-filter. They serve as guide elements when the operating element is rotated. In an alternative embodiment, the pre-filter has at least three pins and the operating element has a centering ring with grooves in which the pins run. If the central filter is arranged in the fifth position of the operating element in the pre-filter, it can be removed together with this and the operating element in the fifth position. However, the central filter can also have already been removed from the pre-filter when the operating element is in the fourth position. In the fifth position, it is irrelevant whether the central filter is in the pre-filter or not.

Bevorzugt ist der Sauggutbehälter derart ausgebildet, dass das Bedienelement und der Vorfilter in der fünften Stellung nur teilweise entnehmbar sind und erst nach Drehen des Bedienelements in eine sechste Stellung, die zwischen der vierten und fünften Stellung liegt, und anschließendem erneutem Drehen in die fünfte Stellung vollständig aus dem Gehäuse entnehmbar ausgebildet sind. Dies ist vorteilhaft, weil der Nutzer dann das Bedienelement und den Vorfilter nur bewusst entnehmen kann, in dem er das Bedienelement von der fünften Stellung in die sechste Stellung in Richtung der vierten Stellung und dann in die fünfte Stellung bewusst dreht. Dadurch wird sichergestellt, dass der Nutzer nicht plötzlich den Vorfilter in der Hand hält, während ihm das Gehäuse durch die Trennung von dem Vorfilter herunterfällt. Unter dem Ausdruck "teilweise entnehmbar" ist zu verstehen, dass die Verbindung zwischen dem Vorfilter und dem Gehäuse nur teilweise und unvollständig gelöst ist.The suction material container is preferably designed in such a way that the operating element and the pre-filter can only be partially removed in the fifth position and can only be completely removed after turning the operating element into a sixth position, which lies between the fourth and fifth position, and then turning it again into the fifth position are designed to be removable from the housing. This is advantageous because the user can then only deliberately remove the control element and the pre-filter by deliberately rotating the control element from the fifth position to the sixth position in the direction of the fourth position and then into the fifth position. This ensures that the user does not suddenly hold the pre-filter in his hand while the housing falls through the separation from the pre-filter. The expression "partially removable" means that the connection between the pre-filter and the housing is only partially and incompletely detached.

Bevorzugt sind die Kreuzrippen kodiert. Bevorzugt sind die Kreuzrippen um einen vorbestimmten Wert versetzt über den Umfang des Vorfilters verteilt angeordnet mit der Ausnahme von einer Kreuzrippe, die um einen anderen Wert als den vorbestimmten Wert versetzt angeordnet ist. Im Fall von drei Kreuzrippe sind zwei Kreuzrippen beispielsweise um 120° versetzt über den Umfang des Vorfilters verteilt angeordnet, während die dritte Kreuzrippe um einen anderen Wert als 120° versetzt angeordnet ist. Dadurch wird die Kodierung bereitgestellt. Bevorzugt weist das Bedienelement Rastpunkte und Einstiegsführungen auf, die dementsprechend kodiert ausgebildet sind. D.h., sie sind bevorzugt um einen vorbestimmten Wert versetzt über den Umfang des Bedienelements verteilt angeordnet mit der Ausnahme von einem Rastpunkt und einer Einstiegsführung, die um einen anderen Wert als den vorbestimmten Wert versetzt angeordnet sind.The cross ribs are preferably encoded. Preferably, the cross ribs are offset by a predetermined amount about the circumference of the prefilter with the exception of one cross rib which is offset by a different amount than the predetermined amount. In the case of three cross ribs, two cross ribs are arranged offset by 120°, for example, over the circumference of the prefilter, while the third cross rib is arranged offset by a value other than 120°. This will make the encoding provided. The control element preferably has latching points and entry guides which are correspondingly encoded. That is, they are preferably offset by a predetermined value distributed over the circumference of the operating element with the exception of a detent point and an entry guide, which are arranged offset by a value other than the predetermined value.

In einer bevorzugten Ausführungsform weist der Zentrierring Rastpunkte auf, die von den Kreuzrippen beim Drehen überwindbar sind, um während des Drehens in die nächste Stellung der ersten, zweiten, dritten, vierten und fünften Stellung zu gelangen. Dadurch wird ein sauberes Positionieren in der jeweiligen Stellung gewährleistet.In a preferred embodiment, the centering ring has latching points which can be overcome by the cross ribs when turning, in order to reach the next position of the first, second, third, fourth and fifth position during turning. This ensures clean positioning in the respective position.

Bevorzugt ist das Bedienelement derart ausgelegt, dass es von der ersten in die zweite Stellung um 20-25° gedreht wird, dass es von der ersten in die dritte Stellung um 42-45° gedreht wird, dass es von der ersten in die vierte Stellung um 77-80° gedreht wird und dass es von der ersten in die fünfte Stellung um 88-90° gedreht wird. bevorzugt ist das Bedienelement derart ausgelegt, dass es von der ersten in die sechste Stellung um 84-86° gedreht wird.The operating element is preferably designed such that it is rotated from the first to the second position by 20-25°, that it is rotated by 42-45° from the first to the third position, that it is rotated from the first to the fourth position is rotated 77-80° and that it is rotated 88-90° from the first to the fifth position. the operating element is preferably designed in such a way that it is rotated by 84-86° from the first to the sixth position.

Bevorzugt ist das Bedienelement derart ausgelegt, dass es zum Öffnen des Sauggutbehälters von der ersten Stellung in die zweite Stellung, von der zweiten Stellung in die dritte Stellung, von der dritten Stellung in die vierte Stellung und von der vierten Stellung in die fünfte Stellung in der angegebenen Reihenfolge drehbar ist. Dadurch wird gewährleistet, dass bei Entnahme des Vorfilters und/oder des Zentralfilters auch der Sauggutsammelraum entleert wird. Darüber hinaus wird hierdurch gewährleistet, dass der Zentralfilter nicht entnommen werden kann, solange sich der Sauggutbehälter noch im Gerätekorpus befindet bzw. der Sauggutbehälter noch nicht entleert wurde. Hierdurch wird verhindert, dass Staub- oder Schmutzpartikel in den Ansaugbereich des Gebläses gelangen.The control element is preferably designed in such a way that it can be used to open the suction material container from the first position to the second position, from the second position to the third position, from the third position to the fourth position and from the fourth position to the fifth position in the specified order can be rotated. This ensures that when the pre-filter and/or the central filter is removed, the suction material collection chamber is also emptied. In addition, this ensures that the central filter cannot be removed as long as the suction material container is still in the device body or the suction material container has not yet been emptied. This prevents dust or dirt particles from getting into the intake area of the fan.
