Definitions
- the invention relates to a hand-held cyclone vacuum cleaner which, for the sake of simplicity, is referred to below as a vacuum cleaner.
- the invention relates to a vacuum cleaner which has a suction material container for receiving suction material and a device body which can be detachably connected to the suction material container and which has a drive unit which is designed to generate a suction air flow.
- a cyclone vacuum cleaner it is necessary that it has a removable suction material container so that the suction material can be removed from the suction material container.
- at least one sealing point When attaching and detaching the suction material container from the device body, at least one sealing point must be contacted or released.
- This at least one sealing point relates in particular to the intake and exhaust air suction stream of the separation system, which is connected upstream of the suction material container.
- this at least one sealing point it is necessary for this at least one sealing point to be optimally pressed during operation, so that losses due to secondary air in addition to the suction air flow are minimized.
- the invention thus poses the problem of providing a vacuum cleaner which has an optimized sealing effect between the suction material container and the device body.
- the advantages that can be achieved with the invention are, in addition to an optimized sealing effect, that a user of the vacuum cleaner is enabled to apply this sealing effect with a relatively low expenditure of force and also to release it again easily.
- a simple, non-destructive overcoming of the mechanism e.g. possible for assembly purposes.
- a pressing force is provided by means of the concept described. During operation, sealing areas pull towards the sealing point. This results in an improved seal when the vacuum cleaner is in operation. This optimizes the sealing effect between the suction material container and the device body.
- the invention relates to a hand-held cyclone vacuum cleaner, having a suction material container for receiving suction material and a device body which can be detachably connected to the suction material container and has a drive unit which is designed to generate a suction air flow, with an air duct located in the suction material container and a suction channel located in the housing body in a connected state of the suction material container and the housing body have an air path of the suction air flow during operation, which is aligned along a flow axis that is parallel to an axis of movement when connecting the suction material container and the device body.
- the vacuum cleaner is operated by hand by the user.
- the vacuum cleaner preferably also has a handle which can be connected to the suction material container and which is connected to it during operation.
- the vacuum cleaner can have a suction tube which can be connected to the suction material container and / or the device body and, during operation, is connected to one of them if necessary.
- the suction tube can still be connected to the handle; this embodiment is advantageous if the suction pipe is connected to the suction material container during operation.
- the suction pipe can also be connected to a floor nozzle; this embodiment is advantageous if the suction tube is connected to the device body during operation and the suction material container is connected to the handle.
- cyclone vacuum cleaner is to be understood as meaning a vacuum cleaner which is bagless and in which eddies and possible turbulences are generated in an air flow entering the vacuum cleaner, whereby the suction material, e.g. Dust particles are pushed and deposited in a predetermined direction due to centrifugal force.
- bagless means that the suction material in the vacuum cleaner is collected directly in the suction material container without a bag or similar replaceable filter medium for receiving suction material being arranged in it, so that the user has to empty the suction material from the suction material container does not remove a bag or the like from the suction material container.
- the vacuum cleaner can, however, have one or more filter media which prevent sucked-up material from reaching the drive unit arranged in the device body. Both the suction material container and the device body are preferably made of plastic.
- the vacuum cleaner is preferably a cordless vacuum cleaner. That is, the vacuum cleaner has an accumulator and is designed to be operated by means of 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.
- the suction material container In an operational working position, the suction material container is located on a back or at the 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.
- the suction channel located in the device body goes into the during operation located in the suction material container via the air duct, that is, the suction air flow flows during operation first through the suction duct and then through the air duct.
- the suction material container is separated from the device body for emptying.
- the suction material container is connected to the device body.
- it is placed on the device body and a suction air flow is generated by the drive unit, which flows through the suction channel of the device body and then through the air channel of the suction material container.
- a prevailing negative pressure pulls the device body and the suction material container towards one another, since the air path of the suction air flow is aligned during operation along the flow axis which is parallel to an axis of movement when connecting the suction material container and the device body. This achieves a high sealing effect between the two components.
- the generated eddies and any eddies in the suction air flow are not taken into account, rather the path of the main flow direction of the suction air flow is meant.
- the device body has a base plate and a nozzle extending away from the base plate and the suction material container has a housing part and a prefilter with a sleeve-like part which is arranged in the housing part, one end of the housing part and an edge of the Device body have a complementary contour and the sleeve-like part can be placed on the socket.
- the suction air flow also flows through the pre-filter and the nozzle, so that the suction air flow first flows through the suction channel, then the air channel, and then through a channel formed by the pre-filter and the nozzle.
- the flow axis of the suction channel and the air channel is preferably parallel to the flow axis of the channel formed by the prefilter and the nozzle. This further improves the sealing effect between the suction material container and the device body.
- the air duct and the duct formed by the nozzle and the prefilter are preferably connected by a connecting duct.
- the flow axes of the suction channel and the air channel are parallel to the flow axis of the channel formed by the connector and the pre-filter, but the main flow direction of the suction air flow flowing through the suction channel and the air channel is opposite to the main flow direction of the channel formed by the connector and the pre-filter, whereby the main flow direction is to be understood as a flow direction in which the eddies and any eddies are disregarded.
- Due to the negative pressure prevailing at the connection during operation the suction material container is additionally drawn towards the device body, which results in an optimized sealing effect at this point.
- connection piece is preferably upstream of the drive unit, for example, in the direction of flow of the suction flow arranged in the form of a fan.
- the sleeve-like part of the prefilter preferably engages over the nozzle when the suction material container is placed on the device body.
- the socket preferably has several locking cams and the pre-filter has several locking geometries, each of which is designed and designed to receive 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 each has a locking part extending away from the respective slot, which is closed in the direction of the base plate and extends at an angle away from the respective slot in the direction opposite to the base plate.
- Each slot of each locking geometry is preferably designed to allow a latching cam of the connector to be at least partially inserted into the sleeve-like part of the prefilter when the suction material container is placed on the device body. This allows the suction material container to be placed on the device body without any additional force being applied. The way for placing is limited by a stop on the respective slot.
- Each locking geometry preferably has a geometry such that the suction material container can be placed in a predetermined position. The system is thereby coded.
- Each locking geometry has the one slot and the one locking part extending away from the respective slot.
- the locking parts are closed in the direction of the base plate and extend at an angle from the respective slot in the direction opposite to the base plate. They therefore have a slope with respect to the respective slot.
- the slots of the locking geometries are each designed in such a way that the locking cams are guided in the slots when the prefilter is placed on the socket. This placement is done by the user without any effort. From this position, the sleeve-like part of the prefilter can be rotated in such a way that the locking cams can be inserted into the respective locking part.
- the sleeve-like part of the prefilter and the connector are preferably designed in such a way that the suction material container pulls onto the connector via the locking cams when the locking cams are turned in the respective locking part via the incline of the locking part located in the prefilter.
- a stroke resulting therefrom is preferably in the range of 2 to 4 mm. Due to this thread-like construction, a high sealing force can be applied with comparatively little manual force.
- connection piece and the prefilter are preferably each at least partially conical.
- the connecting piece is preferably equipped with a conical geometry which is designed to come into contact with the prefilter via a sealing area during the stroke when the Suction material container is connected to the device body.
- the prefilter is preferably also conical in the sealing area, ie the sleeve-like part is preferably at least partially conical.
- the locking cams are preferably distributed at a uniform angle over the circumference of the connecting piece and the locking geometries are distributed uniformly over the circumference of the pre-filter. This results in a uniform distribution of a force when locking the suction material container on the device body.
- the connector has three locking cams and the prefilter has three locking geometries.
- the vacuum cleaner has an operating element which is connected to the suction material container in such a way that the suction material container is arranged between the operating element and the device body and that the operating element is designed to be rotatable from an open position to a closed position and vice versa.
- the operating element is preferably designed to lock or release the suction material container on the device body.
- the locking geometries are preferably designed in such a way that, in the connected state of the suction material container and the housing body, the latching cams are inserted into the respective locking part when the operating element is in the closed position and, when the operating element is in the open position, in are inserted into the respective slot.
- the vacuum cleaner is designed in such a way that when the operating element is turned into the closed position, the suction material container pulls itself over the slope in the pre-filter in the locking geometry, ie the locking part, via the locking cams onto the socket.
- the stroke resulting therefrom is preferably in the range from 2 to 4 mm.
- the vacuum cleaner has inlet bevels which are each arranged on the pre-filter adjacent to one of the locking parts and adjacent to the slot assigned to the respective locking part, the locking cams each having a bevel on their bevel when the suction material container is placed on the device body Side.
- the prefilter When the prefilter is placed on the nozzle, it springs open through contact between the locking cams and the inlet bevels and the locking cams jump into the locking parts of the locking geometries in an end position. This allows the pre-filter to be placed on the nozzle without the locking cams having to be guided in the slots. This prevents the components from being destroyed if the user makes a mistake when placing the suction material container on the device body.
- the suction material container does not have to be rotated in order to connect it to the device body.
- the suction material container can be connected to the device body, even when the control element is in the closed position.

Description
Die Erfindung betrifft einen handgeführten Zyklon-Staubsauger, der nachfolgend der Einfachheit halber als Staubsauger bezeichnet wird. Insbesondere betrifft die Erfindung einen Staubsauger, der einen Sauggutbehälter zur Aufnahme von Sauggut und einen Gerätekorpus aufweist, der lösbar mit dem Sauggutbehälter verbindbar ist und ein Antriebsaggregat aufweist, das ausgebildet ist, einen Saugluftstrom zu erzeugen.The invention relates to a hand-held cyclone vacuum cleaner which, for the sake of simplicity, is referred to below as a vacuum cleaner. In particular, the invention relates to a vacuum cleaner which has a suction material container for receiving suction material and a device body which can be detachably connected to the suction material container and which has a drive unit which is designed to generate a suction air flow.
Bei einem Zyklon-Staubsauger ist es notwendig, dass er einen abnehmbaren Sauggutbehälter aufweist, damit das aufgesaugte Sauggut aus dem Sauggutbehälter entfernt werden kann. Beim Aufsetzen und Lösen des Sauggutbehälters von dem Gerätekorpus muss mindestens eine Dichtstelle kontaktiert bzw. gelöst werden. Diese mindestens eine Dichtstelle betrifft insbesondere den Zu- und Abluft-Saugstrom des Abscheidesystems, das dem Sauggutbehälter vorgeschaltet ist. Zudem ist es aber notwendig, dass bei dieser mindestens einen Dichtstelle bei Betrieb eine optimale Anpressung erfolgt, so dass Verluste durch Nebenluft neben dem Saugluftstrom minimiert werden.In the case of a cyclone vacuum cleaner, it is necessary that it has a removable suction material container so that the suction material can be removed from the suction material container. When attaching and detaching the suction material container from the device body, at least one sealing point must be contacted or released. This at least one sealing point relates in particular to the intake and exhaust air suction stream of the separation system, which is connected upstream of the suction material container. In addition, however, it is necessary for this at least one sealing point to be optimally pressed during operation, so that losses due to secondary air in addition to the suction air flow are minimized.
Der Erfindung stellt sich somit das Problem, einen Staubsauger bereitzustellen, der eine optimierte Dichtwirkung zwischen dem Sauggutbehälter und dem Gerätekorpus aufweist.The invention thus poses the problem of providing a vacuum cleaner which has an optimized sealing effect between the suction material container and the device body.
Erfindungsgemäß wird dieses Problem durch einen 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 vacuum cleaner having the features of
Die mit der Erfindung erreichbaren Vorteile bestehen neben einer optimierten Dichtwirkung darin, dass einem Nutzer des Staubsaugers ermöglicht wird, diese Dichtwirkung mit einem relativ geringen Kraftaufwand aufzubringen und aber auch leicht wieder zu lösen. Zudem ist ein einfaches, zerstörungsfreies Überwinden des Mechanismus z.B. für Montagezwecke möglich. Mittels des beschriebenen Konzepts wird eine Anpresskraft bereitgestellt. Bei Betrieb ziehen sich Dichtbereiche an der Dichtstelle heran. Dadurch erfolgt beim Betrieb des Staubsaugers eine verbesserte Abdichtung. Dadurch wird die Dichtwirkung zwischen dem Sauggutbehälter und dem Gerätekorpus optimiert.The advantages that can be achieved with the invention are, in addition to an optimized sealing effect, that a user of the vacuum cleaner is enabled to apply this sealing effect with a relatively low expenditure of force and also to release it again easily. In addition, a simple, non-destructive overcoming of the mechanism e.g. possible for assembly purposes. A pressing force is provided by means of the concept described. During operation, sealing areas pull towards the sealing point. This results in an improved seal when the vacuum cleaner is in operation. This optimizes the sealing effect between the suction material container and the device body.

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.The expression “hand-held” means that the vacuum cleaner is operated by hand by the user. For this purpose, the vacuum cleaner preferably also has a handle which can be connected to the suction material container and which is connected to it during operation.
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. Optional kann das Saugrohr weiterhin mit dem Handgriff verbunden sein; diese Ausführungsform ist vorteilhaft, wenn das Saugrohr bei Betrieb mit dem Sauggutbehälter verbunden ist. Das Saugrohr kann weiterhin mit einer Bodendüse verbunden sein; diese Ausführungsform ist vorteilhaft, wenn das Saugrohr bei Betrieb mit dem Gerätekorpus verbunden ist und der Sauggutbehälter mit dem Handgriff verbunden ist.Furthermore, the vacuum cleaner can have a suction tube which can be connected to the suction material container and / or the device body and, during operation, is connected to one of them if necessary.

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" is to be understood as meaning a vacuum cleaner which is bagless and in which eddies and possible turbulences are generated in an air flow entering the vacuum cleaner, whereby the suction material, e.g. Dust particles are pushed and deposited in a predetermined direction due to centrifugal force. The expression "bagless" means that the suction material in the vacuum cleaner is collected directly in the suction material container without a bag or similar replaceable filter medium for receiving suction material being arranged in it, so that the user has to empty the suction material from the suction material container does not remove a bag or the like from the suction material container. The vacuum cleaner can, however, have one or more filter media which prevent sucked-up material from reaching 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 by means of 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.
In einer betriebsgemäßen Arbeitsposition befindet sich der Sauggutbehälter an einer Rückseite bzw. am hinterem Ende des Staubsaugers, womit gemeint ist, dass er näher an der Hand des Nutzers und weiter von dem zu saugenden Untergrund entfernt ist als der Gerätekorpus. Der sich in dem Gerätekorpus befindende Saugkanal geht bei Betrieb in den sich in dem Sauggutbehälter befindenden Luftkanal über, d.h., der Saugluftstrom strömt bei Betrieb zuerst durch den Saugkanal und dann durch den Luftkanal.In an operational working position, the suction material container is located on a back or at the 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. The suction channel located in the device body goes into the during operation located in the suction material container via the air duct, that is, the suction air flow flows during operation first through the suction duct and then through the air duct.
Zum Entleeren ist der Sauggutbehälter vom dem Gerätekorpus getrennt. Bei Betrieb ist der Sauggutbehälter mit dem Gerätekorpus verbunden. Dazu ist er auf den Gerätekorpus aufgesetzt und durch das Antriebsaggregat wird ein Saugluftstrom erzeugt, der durch den Saugkanal des Gerätekorpus und dann durch den Luftkanal des Sauggutbehälters strömt. Durch einen herrschenden Unterdruck werden der Gerätekorpus und der Sauggutbehälter zueinander gezogen, da der Luftweg des Saugluftstroms bei Betrieb entlang der Strömungsachse ausgerichtet ist, die parallel zu einer Bewegungsachse beim Verbinden des Sauggutbehälters und des Gerätekorpus ist. Dadurch wird eine hohe Dichtwirkung zwischen den beiden Bauteilen erzielt. Bei dem Luftweg bleiben die erzeugten Wirbel und etwaige Verwirbelungen des Saugluftstroms unberücksichtigt, gemeint ist vielmehr der Weg der Hauptströmungsrichtung des Saugluftstroms.The suction material container is separated from the device body for emptying. During operation, the suction material container is connected to the device body. For this purpose, it is placed on the device body and a suction air flow is generated by the drive unit, which flows through the suction channel of the device body and then through the air channel of the suction material container. A prevailing negative pressure pulls the device body and the suction material container towards one another, since the air path of the suction air flow is aligned during operation along the flow axis which is parallel to an axis of movement when connecting the suction material container and the device body. This achieves a high sealing effect between the two components. In the case of the air path, the generated eddies and any eddies in the suction air flow are not taken into account, rather the path of the main flow direction of the suction air flow is meant.
In einer bevorzugten Ausführungsform weist der Gerätekorpus eine Basisplatte und einen sich von der Basisplatte weg erstreckenden Stutzen auf und weist der Sauggutbehälter ein Gehäuseteil und einen Vorfilter mit einem hülsenartigen Teil auf, der in dem Gehäuseteil angeordnet ist, wobei ein Ende des Gehäuseteils und ein Rand des Gerätekorpus eine komplementäre Kontur aufweisen und der hülsenartige Teil auf den Stutzen aufsetzbar ist. Bei Betrieb strömt der Saugluftstrom ebenfalls durch den Vorfilter und den Stutzen, sodass der Saugluftstrom zuerst durch den Saugkanal, dann den Luftkanal, und anschließend durch einen durch den Vorfilter und den Stutzen gebildeten Kanal strömt. Die Strömungsachse des Saugkanals und des Luftkanals ist bevorzugt parallel zu der Strömungsachse des durch den Vorfilter und den Stutzen gebildeten Kanals. Dadurch wird die Dichtwirkung zwischen dem Sauggutbehälter und dem Gerätekorpus weiterhin verbessert.In a preferred embodiment, the device body has a base plate and a nozzle extending away from the base plate and the suction material container has a housing part and a prefilter with a sleeve-like part which is arranged in the housing part, one end of the housing part and an edge of the Device body have a complementary contour and the sleeve-like part can be placed on the socket. During operation, the suction air flow also flows through the pre-filter and the nozzle, so that the suction air flow first flows through the suction channel, then the air channel, and then through a channel formed by the pre-filter and the nozzle. The flow axis of the suction channel and the air channel is preferably parallel to the flow axis of the channel formed by the prefilter and the nozzle. This further improves the sealing effect between the suction material container and the device body.
Der Luftkanal und der durch den Stutzen und den Vorfilter gebildeten Kanal sind bevorzugt durch einen Verbindungskanal verbunden. Die Strömungsachsen des Saugkanals und des Luftkanals sind parallel zu der Strömungsachse des durch den Stutzen und Vorfilters gebildeten Kanals, aber die Hauptströmungsrichtung des durch den Saugkanal und den Luftkanal strömenden Saugluftstroms ist entgegengesetzt zu der Hauptströmungsrichtung des durch den durch den Stutzen und den Vorfilter gebildeten Kanals, wobei unter der Hauptströmungsrichtung eine Strömungsrichtung zu verstehen ist, bei der die Wirbel und etwaige Verwirbelungen außer Acht gelassen werden. Durch den im Betrieb beim Stutzen herrschenden Unterdruck erfolgt zudem ein zusätzliches Heranziehen des Sauggutbehälters an den Gerätekorpus, was eine optimierte Dichtwirkung an dieser Stelle bewirkt. Der Stutzen ist bevorzugt in Strömungsrichtung des Saugstroms vor dem Antriebsaggregat beispielsweise in Form eines Gebläses angeordnet. Bevorzugt greift der hülsenartige Teil des Vorfilters über den Stutzen, wenn der Sauggutbehälter auf den Gerätekorpus aufgesetzt ist.The air duct and the duct formed by the nozzle and the prefilter are preferably connected by a connecting duct. The flow axes of the suction channel and the air channel are parallel to the flow axis of the channel formed by the connector and the pre-filter, but the main flow direction of the suction air flow flowing through the suction channel and the air channel is opposite to the main flow direction of the channel formed by the connector and the pre-filter, whereby the main flow direction is to be understood as a flow direction in which the eddies and any eddies are disregarded. Due to the negative pressure prevailing at the connection during operation, the suction material container is additionally drawn towards the device body, which results in an optimized sealing effect at this point. The connection piece is preferably upstream of the drive unit, for example, in the direction of flow of the suction flow arranged in the form of a fan. The sleeve-like part of the prefilter preferably engages over the nozzle when the suction material container is placed on the device body.
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. 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.The socket preferably has several locking cams and the pre-filter has several locking geometries, each of which is designed and designed to receive 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 each has a locking part extending away from the respective slot, which is closed in the direction of the base plate and extends at an angle away from the respective slot in the direction opposite to the base plate. Each slot of each locking geometry is preferably designed to allow a latching cam of the connector to be at least partially inserted into the sleeve-like part of the prefilter when the suction material container is placed on the device body. This allows the suction material container to be placed on the device body without any additional force being applied. The way for placing is limited by a stop on the respective slot. Each locking geometry preferably has a geometry such that the suction material container can be placed in a predetermined position. The system is thereby coded.
Jede Verriegelungsgeometrie weist den einen Schlitz und den einen sich von dem jeweiligen Schlitz weg erstreckenden Verriegelungsteil auf. Die Verriegelungsteile sind in Richtung der Basisplatte hin geschlossen und erstrecken sich winklig von dem jeweiligen Schlitz in die zu der Basisplatte entgegengesetzte Richtung. Sie weisen daher eine Steigung in Bezug auf den jeweiligen Schlitz auf.Each locking geometry has the one slot and the one locking part extending away from the respective slot. The locking parts are closed in the direction of the base plate and extend at an angle from the respective slot in the direction opposite to the base plate. They therefore have a slope with respect to the respective slot.
In einer bevorzugten Ausführungsform sind die Schlitze der Verriegelungsgeometrien jeweils derart ausgebildet, dass beim Aufsetzen des Vorfilters auf den Stutzen die Rastnocken in den Schlitzen geführt werden. Dieses Aufsetzen wird vom Nutzer ohne Kraftaufwand realisiert. Von dieser Position aus, ist der hülsenartige Teil des Vorfilters derart drehbar, dass die Rastnocken in den jeweiligen Verriegelungsteil einführbar sind. Der hülsenartige Teil des Vorfilters und der Stutzen sind bevorzugt derart ausgebildet, dass sich der Sauggutbehälter bei Drehen der Rastnocken in den jeweiligen Verriegelungsteil über die im Vorfilter befindliche Steigung des Verriegelungsteils über die Rastnocken auf den Stutzen zieht. Ein Hub, welcher daraus resultiert, ist bevorzugt im Bereich von 2 bis 4 mm. Durch diese gewindeartige Konstruktion kann mit einer vergleichsweisen geringen Handkraft eine hohe Dichtkraft aufgebracht werden.In a preferred embodiment, the slots of the locking geometries are each designed in such a way that the locking cams are guided in the slots when the prefilter is placed on the socket. This placement is done by the user without any effort. From this position, the sleeve-like part of the prefilter can be rotated in such a way that the locking cams can be inserted into the respective locking part. The sleeve-like part of the prefilter and the connector are preferably designed in such a way that the suction material container pulls onto the connector via the locking cams when the locking cams are turned in the respective locking part via the incline of the locking part located in the prefilter. A stroke resulting therefrom is preferably in the range of 2 to 4 mm. Due to this thread-like construction, a high sealing force can be applied with comparatively little manual force.
Bevorzugt sind der Stutzen und der Vorfilter zumindest teilweise jeweils konisch ausgebildet. Bevorzugt ist der Stutzen mit einer konischen Geometrie ausgestattet, die ausgebildet ist, sich bei dem Hub über einen Dichtbereich an den Vorfilter anzulegen, wenn der Sauggutbehälter mit dem Gerätekorpus verbunden wird. Der Vorfilter ist im Dichtbereich bevorzugt ebenfalls konisch ausgebildet, d.h. bevorzugt ist der hülsenartige Teil zumindest teilweise konisch ausgebildet. Durch Anlegen des Sauggutbehälters an den Gerätekorpus wird auch eine Abdichtung zwischen dem Saugkanal und dem Luftkanal bereitgestellt. Die konische Geometrie des Stutzens ist bevorzugt weiterhin derart ausgebildet, dass beim Lösen des Sauggutbehälters von dem Gerätekorpus die Steigung des Verriegelungsteils bewirkt, dass sich der Stutzen und der Vorfilter leicht voneinander trennen lassen. Mittels der konischen Ausgestaltung wird eine Flächendichtung bereitgestellt.The connection piece and the prefilter are preferably each at least partially conical. The connecting piece is preferably equipped with a conical geometry which is designed to come into contact with the prefilter via a sealing area during the stroke when the Suction material container is connected to the device body. The prefilter is preferably also conical in the sealing area, ie the sleeve-like part is preferably at least partially conical. By placing the suction material container on the device body, a seal is also provided between the suction channel and the air channel. The conical geometry of the connector is preferably also designed in such a way that when the suction material container is released from the device body, the slope of the locking part causes the connector and the pre-filter to be easily separated from one another. A surface seal is provided by means of the conical configuration.
Bevorzugt sind die Rastnocken in einem gleichmäßigen Winkel über den Umfang des Stutzens verteilt und sind die Verriegelungsgeometrien gleichmäßig über den Umfang des Vorfilters verteilt. Dadurch ergibt sich eine gleichmäßige Verteilung einer Kraft beim Arretieren des Sauggutbehälters an dem Gerätekorpus. Beispielsweise weist der Stutzen drei Rastnocken und der Vorfilter drei Verriegelungsgeometrien auf.The locking cams are preferably distributed at a uniform angle over the circumference of the connecting piece and the locking geometries are distributed uniformly over the circumference of the pre-filter. This results in a uniform distribution of a force when locking the suction material container on the device body. For example, the connector has three locking cams and the prefilter has three locking geometries.
In einer bevorzugten Ausführungsform weist der Staubsauger ein Bedienelement auf, das mit dem Sauggutbehälter derart verbunden ist, dass der Sauggutbehälter zwischen dem Bedienelement und dem Gerätekorpus angeordnet ist und dass das Bedienelement von einer offenen Stellung in eine geschlossene Stellung und umgekehrt drehbar ausgebildet ist. Das Bedienelement ist bevorzugt ausgebildet, den Sauggutbehälter an dem Gerätekorpus zu arretieren bzw. zu lösen. Wenn das Bedienelement in der offenen Stellung angeordnet ist, ist der Sauggutbehälter von dem Gerätekorpus gelöst oder lösbar verbunden (d.h. der Sauggutbehälter kann von dem Gerätekorpus durch Ziehen weitestgehend kraftfrei von diesem gelöst werden). Wenn das Bedienelement in der geschlossenen Stellung angeordnet ist, ist der Sauggutbehälter mit dem Gerätekorpus verbunden, d.h. er kann von ihm nicht durch Ziehen von diesem gelöst werden. Vielmehr muss das Bedienelement von der geschlossenen Stellung in die offene Stellung gedreht werden, damit der Sauggutbehälter von dem Gerätekorpus mittels Ziehen lösbar ist.In a preferred embodiment, the vacuum cleaner has an operating element which is connected to the suction material container in such a way that the suction material container is arranged between the operating element and the device body and that the operating element is designed to be rotatable from an open position to a closed position and vice versa. The operating element is preferably designed to lock or release the suction material container on the device body. When the control element is arranged in the open position, the suction material container is detached from the device body or detachably connected (i.e. the suction material container can be detached from the device body by pulling it largely without force). When the control element is arranged in the closed position, the suction material container is connected to the device body, i. it cannot be detached from it by pulling it from it. Rather, the operating element must be rotated from the closed position to the open position so that the suction material container can be detached from the device body by means of pulling.
Bevorzugt sind die Verriegelungsgeometrien derart ausgebildet, dass in dem verbundenen Zustand des Sauggutbehälters und des Gehäusekorpus die Rastnocken, wenn sich das Bedienelement in der geschlossenen Stellung befindet, in den jeweiligen Verriegelungsteil eingeführt sind, und, wenn das Bedienelement in der offenen Stellung angeordnet ist, in den jeweiligen Schlitz eingeführt sind. Der Staubsauger ist derart ausgebildet, dass sich der Sauggutbehälter bei Drehen des Bedienelements in die geschlossene Stellung über die im Vorfilter befindliche Steigung in der Verriegelungsgeometrie, d.h. den Verriegelungsteil, über die Rastnocken auf den Stutzen zieht. Der Hub, welcher daraus resultiert, ist bevorzugt im Bereich von 2 bis 4 mm.The locking geometries are preferably designed in such a way that, in the connected state of the suction material container and the housing body, the latching cams are inserted into the respective locking part when the operating element is in the closed position and, when the operating element is in the open position, in are inserted into the respective slot. The vacuum cleaner is designed in such a way that when the operating element is turned into the closed position, the suction material container pulls itself over the slope in the pre-filter in the locking geometry, ie the locking part, via the locking cams onto the socket. The stroke resulting therefrom is preferably in the range from 2 to 4 mm.
In einer bevorzugten Ausführungsform weist der Staubsauger Einlaufschrägen auf, die jeweils an dem Vorfilter angrenzend zu einem der Verriegelungsteile und benachbart zu dem jeweiligen Verriegelungsteil zugeordnetem Schlitz angeordnet sind, wobei die Rastnocken jeweils eine Fase an ihrer beim Aufsetzen des Sauggutbehälters auf den Gerätekorpus zu der Einlaufschräge gerichteten Seite aufweisen. Beim Aufsetzen des Vorfilters auf den Stutzen federt er durch einen Kontakt zwischen den Rastnocken und den Einlaufschrägen auf und die Rastnocken springen in einer Endposition in die Verriegelungsteile der Verriegelungsgeometrien. Dadurch kann der Vorfilter auf den Stutzen ausgesetzt werden, ohne dass die Rastnocken in den Schlitzen geführt werden müssen. Dadurch wird eine Zerstörung der Bauteile unterbunden, wenn der Nutzer eine Fehlbedienung beim Aufsetzen des Sauggutbehälters auf den Gerätekorpus unterläuft. Zudem muss bei einer Montage in der Fertigung des Staubsaugers der Sauggutbehälter nicht gedreht werden, um ihn mit dem Gerätekorpus zu verbinden. Dadurch kann der Sauggutbehälter mit dem Gerätekorpus verbunden werden, auch wenn sich das Bedienelement in der geschlossenen Stellung befindet.In a preferred embodiment, the vacuum cleaner has inlet bevels which are each arranged on the pre-filter adjacent to one of the locking parts and adjacent to the slot assigned to the respective locking part, the locking cams each having a bevel on their bevel when the suction material container is placed on the device body Side. When the prefilter is placed on the nozzle, it springs open through contact between the locking cams and the inlet bevels and the locking cams jump into the locking parts of the locking geometries in an end position. This allows the pre-filter to be placed on the nozzle without the locking cams having to be guided in the slots. This prevents the components from being destroyed if the user makes a mistake when placing the suction material container on the device body. In addition, during assembly in the production of the vacuum cleaner, the suction material container does not have to be rotated in order to connect it to the device body. As a result, the suction material container can be connected to the device body, even when the control element is in the closed position.
