Description

Die Erfindung betrifft einen Staubsauger mit einem walzenförmig ausgebildeten Gehäuse, an dessen beiden Stirnseiten Laufräder drehbar angeordnet sind, in dem das Gebläseaggregat des Staubsaugers eingebaut ist und das einen Aufnahmeraum für einen Filterbeutel aufweist, wobei eine Führungsstange an das Gehäuse angekoppelt und eine Lufteintrittsöffnung vorgesehen ist, mit der ein Staubsaugermundstück koppelbar ist.The invention relates to a vacuum cleaner with a roller-shaped housing, impellers are rotatably arranged on its two end faces, in which the Blower unit of the vacuum cleaner is installed and that is a receiving space for one Has filter bag, a guide rod coupled to the housing and one Air inlet opening is provided, with which a vacuum cleaner mouthpiece can be coupled.

Ein solcher Staubsauger ist durch die DE-C-637 173 bekannt. Bei diesem bekannten Staubsauger ist an der in Bezug auf die Arbeitsrichtung des Staubsaugers vorderen Gehäuseseite ein die Lufteintrittsöffnung des Staubsaugers bildender Anschlussstutzen vorgesehen. An diesen Anschlussstutzen kann ein Staubsaugermundstück direkt angesteckt oder ein Saugschlauch angeschlossen werden. Mit dem Saugschlauch kann ein mit einem Saugmundstück bestücktes Saugrohr verbunden werden, so dass das Saugmundstück mittels des Saugrohres über eine zu reinigende Fläche geführt werden kann. Mit dem Staubsaugergehäuse ist ferner eine Führungsstange verbunden, durch die der Staubsauger bei direkt angestecktem Staubsaugermundstück über die zu reinigende Fläche bewegbar ist. Auf Grund der konstruktiven Gestaltung des Staubsaugers ergibt sich bei direkt angestecktem Staubsaugermundstück durch die auf das Staubsaugergehäuse ausgeübte Schiebekraft eine hohe Anpresskraft des Staubsaugermundstückes an die zu reinigende Fläche, wodurch die aufzubringende Schiebekraft nochmals erhöht wird. Will der Benutzer eines solchen Staubsaugers mit an dem Saugrohr angesteckten Staubsaugermundstück arbeiten, dann muss er erst eine Demontage des direkt angesteckten Staubsaugermundstückes vornehmen und danach den Saugschlauch an den Anschlussstutzen anschließen.Such a vacuum cleaner is known from DE-C-637 173. In this well-known Vacuum cleaner is on the front in relation to the working direction of the vacuum cleaner A connection piece forming the air inlet opening of the vacuum cleaner on the housing side intended. A vacuum cleaner nozzle can be connected directly to this connection plugged in or a suction hose connected. With the suction hose a suction pipe equipped with a suction nozzle can be connected so that the Suction mouthpiece are guided over a surface to be cleaned by means of the suction pipe can. A guide rod is also connected to the vacuum cleaner housing, through which the vacuum cleaner with the vacuum cleaner mouthpiece plugged in directly over the one to be cleaned Surface is movable. Due to the design of the vacuum cleaner results with a directly attached vacuum cleaner mouthpiece through the on the Vacuum cleaner housing exerted pushing force a high contact pressure of the Vacuum cleaner mouthpiece on the surface to be cleaned, which means the to be applied Pushing force is increased again. Does the user of such a vacuum cleaner want to vacuum cleaner mouthpiece attached, then he must first Disassemble the directly attached vacuum cleaner mouthpiece and then Connect the suction hose to the connecting piece.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art so weiterzubilden, dass seine Benutzung wesentlich vereinfacht und erleichtert ist.The invention has for its object a vacuum cleaner of the beginning further described type so that its use is significantly simplified and is relieved.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Staubsaugermundstück zur Drehachse der Laufräder parallel verschwenkbar am Staubsaugergehäuse angeordnet ist.According to the invention, this object is achieved in that the vacuum cleaner mouthpiece can be pivoted parallel to the axis of rotation of the impellers on the vacuum cleaner housing is arranged.

Hierdurch ist das Staubsaugermundstück von der auf das Staubsaugergehäuse ausgeübten Schiebekraft entkoppelt, so dass zum Fortbewegen des Staubsaugers weniger Kraftaufwand erforderlich ist. As a result, the vacuum cleaner mouthpiece is from the to the vacuum cleaner housing exerted pushing force decouples, so that to move the vacuum cleaner less effort is required.

Die Durchführung von Saugarbeiten mittels eines gegenüber dem Staubsaugergehäuse gesondert handhabbaren Saugmundstückes wird dadurch erleichtert, dass die Führungsstange als Saugrohr ausgebildet und innerhalb des Staubsaugergehäuses eine Umschalteinrichtung vorgesehen ist, mittels derer der Strömungsweg der Saugluft zwischen dem mit der Lufteintrittsöffnung gekoppelten Staubsaugermundstück und einem mit der als Saugrohr ausgebildeten Führungsstange verbundenen Saugmundstück umschaltbar ist. Somit können ohne aufwendiges Umstecken eines Saugschlauches oder Saugrohres Arbeiten mit einem weiteren Saugmundstück durchgeführt werden.The execution of suction work by means of a vacuum cleaner housing separately manageable suction mouthpiece is facilitated in that the Guide rod designed as a suction tube and inside the vacuum cleaner housing Switching device is provided, by means of which the flow path of the suction air between the vacuum cleaner mouthpiece coupled to the air inlet opening and one with the suction mouthpiece connected as a suction tube is switchable. Thus, without having to re-plug a suction hose or Suction tube work can be carried out with another suction mouthpiece.

Vorteilhaft ist es, dass das Staubsaugermundstück um die Drehachse der Laufräder verschwenkbar an den Lagerachsen der Laufräder angeordnet ist.It is advantageous that the vacuum cleaner nozzle around the axis of rotation of the wheels is pivotally arranged on the bearing axles of the impellers.

Bei einer um die Drehachse der Laufräder verschwenkbaren Anordnung des Staubsaugermundstückes kann vorteilhafterweise mindestens die Lagerachse eines Laufrades hohl ausgebildet sein und als Lufteintrittsöffnung dienen.With an arrangement of the pivotable about the axis of rotation of the impellers Vacuum cleaner mouthpiece can advantageously at least the bearing axis Impeller be hollow and serve as an air inlet opening.

Für die Durchführung von verschiedenen Saugarbeiten ist nur ein einziges Staubsaugermundstück erforderlich, wenn das Staubsaugermundstück aus seiner Verschwenkverbindung mit dem Staubsaugergehäuse lösbar und strömungsmäßig mit einer als Saugrohr ausgebildeten Führungsstange gekoppelt ist, die selbst über einen Saugschlauch mit der Lufteintrittsöffnung des Staubsaugergehäuses verbunden ist. Mittels der Führungsstange kann das Staubsaugermundstück aus seiner Verschwenkverbindung mit dem Staubsaugergehäuse gelöst werden und dann unmittelbar mittels der Führungsstange über eine zu reinigende Fläche bewegt werden.There is only one for performing various suction work Vacuum cleaner mouthpiece required when the vacuum cleaner mouthpiece comes out of its Swivel connection with the vacuum cleaner housing detachable and with flow a guide rod designed as a suction tube is coupled, which itself via a Suction hose is connected to the air inlet opening of the vacuum cleaner housing. By means of the guide rod, the vacuum cleaner nozzle can Pivot connection with the vacuum cleaner housing can be released and then be moved directly by means of the guide rod over a surface to be cleaned.

Eine stabile Lage des Staubsaugergehäuses wird dadurch erreicht, dass auf der in bezug auf die Arbeitsrichtung des Staubsaugers hinten liegenden Rückseite des Staubsaugergehäuses ein Abstützelement angeordnet ist.A stable position of the vacuum cleaner housing is achieved by the fact that the on the working direction of the rear of the vacuum cleaner Vacuum cleaner housing a support element is arranged.

Mit 1 ist das walzenförmig ausgebildete Gehäuse eines Staubsaugers bezeichnet. An seinen beiden Stirnseiten ist dieses Gehäuse 1 mit drehbar gelagerten Laufrädern 2 versehen. An der in Bezug auf die Arbeitsrichtung des Staubsaugers hinteren Seite des Staubsaugergehäuses, also an dessen Rückseite, ist ein Gehäuseansatz 3 angeformt, an dem ein der Lagestabilisierung dienendes Abstützelement 4 angebracht ist. Dieser Gehäuseansatz 3 ist außerdem als Luftführungskanal ausgebildet, der mit dem im Staubsaugegehäuse eingebauten Gebläseaggregat des Staubsaugers in Strömungsverbindung bringbar ist. An dem Gehäuseansatz 3 ist eine als Saugrohr ausgebildete Führungsstange 5 verschwenkbar angekoppelt, die außerdem strömungsmäßig mit dem Luftführungskanal verbunden ist. Innerhalb des Staubsaugergehäuses ist eine über eine Tritthebel 6 betätigbare Umschalteinrichtung vorgesehen, mittels derer der Luftströmungsweg zwischen einem an der Vorderseite des Staubsaugergehäuses 1 angeordneten Staubsaugermundstückes 7 und dem Luftführungskanal des Gehäuseansatzes 3 umgeschaltet werden kann. Das Staubsaugermundstück 7 ist in Umfangsrichtung des walzenförmigen Gehäuses verschwenkbar angeordnet. Es kann somit parallel zur Drehachse der Laufräder 2 verschwenkt werden. Damit liegt das Staubsaugermundstück 7 nur durch sein eigenes Gewicht auf der abzusaugenden Fläche auf. Über die Führungsstange 5 auf das Staubsaugergehäuse 1 ausgeübte Kräfte wirken sich daher nicht als Andrückkräfte auf das Staubsaugermundstück 7 aus.The roller-shaped housing of a vacuum cleaner is designated by 1. On its two end faces is this housing 1 with rotatably mounted impellers 2 Mistake. On the rear side of the vacuum cleaner in relation to the working direction Vacuum cleaner housing, that is, on the back, a housing extension 3 is formed on to which a support element 4 serving to stabilize the position is attached. This Housing approach 3 is also designed as an air duct, which with the Vacuum cleaner housing built-in blower unit of the vacuum cleaner in Flow connection can be brought. On the housing attachment 3 is a suction pipe trained guide rod 5 pivotally coupled, which also is fluidly connected to the air duct. Within the Vacuum cleaner housing is a switching device which can be actuated via a step lever 6 provided by means of which the air flow path between one at the front of the Vacuum cleaner housing 1 arranged vacuum cleaner mouthpiece 7 and Air duct of the housing approach 3 can be switched. The Vacuum cleaner mouthpiece 7 is in the circumferential direction of the cylindrical housing arranged pivotable. It can thus be parallel to the axis of rotation of the impellers 2 be pivoted. So that the vacuum cleaner mouthpiece 7 is only by its own Weight on the surface to be extracted. About the guide rod 5 on the Forces exerted by vacuum cleaner 1 therefore do not act as pressure forces the vacuum cleaner mouthpiece 7.

Wie bereits erwähnt kann mittels des Tritthebels 6 eine Umschalteinrichtung betätigt werden, durch die der Strömungsweg der Saugluft zu dem Staubsaugermundstück 7 abgesperrt und zu dem Luftführungskanal in dem Gehäuseansatz 3 freigegeben wird. Damit ist dann die Führungsstange 5 strömungsmäßig mit dem Gebläseaggregat des Staubsaugers verbunden. Zweckmäßigerweise wird an das freie Ende der Führungsstange 5 über einen Saugschlauch ein weiteres Saugmundstück angeschlossen, beispielsweise eine Polster- oder Möbeldüse, mit denen spezielle Saugarbeiten durchgeführt werden können. Zur Aktivierung eines solchen weiteren Saugmundstückes muß also lediglich über den Tritthebel 6 die Umschalteinrichtung betätigt werden undAs already mentioned, a switching device can be actuated by means of the pedal lever 6 through which the flow path of the suction air to the vacuum cleaner mouthpiece 7 blocked and released to the air duct in the housing approach 3. So that the guide rod 5 is then in terms of flow with the blower unit Vacuum cleaner connected. Appropriately, the free end of the Guide rod 5 connected to another suction mouthpiece via a suction hose, For example, an upholstery or furniture nozzle with which special suction work can be carried out. To activate such a further suction mouthpiece So the switching device must only be operated via the pedal lever 6 and

gegebenenfalls der Saugschlauch mit dem weiteren Saugmundstück an die Führungsstange 5 angeschlossen werden.if necessary, the suction hose with the further suction mouthpiece to the Guide rod 5 can be connected.

Bei dem weiteren Ausführungsbeispiel eines Staubsaugers gemäß Fig. 3 und 4 ist das Staubsaugermundstück 7 um die Drehachse der Laufräder 2 verschwenkbar an deren Lagerachsen angelenkt. Dabei kann beispielsweise mindestens die Lagerachse eines der Laufräder 2 hohl ausgebildet sein und somit als Lufteintrittsöffnung für das Staubsaugermundstück 7 dienen. Dadurch wird ein axialer Lufteintritt in den im Staubsaugergehäuse 1 vorgesehenen Staubraum erreicht.In the further embodiment of a vacuum cleaner according to FIGS. 3 and 4, this is Vacuum cleaner mouthpiece 7 pivotable about the axis of rotation of the impellers 2 on the latter Bearing axles articulated. For example, at least the bearing axis can be one of the Impellers 2 can be hollow and thus as an air inlet opening for the Serve vacuum cleaner mouthpiece 7. This will prevent axial air from entering the Vacuum cleaner housing 1 provided dust space is reached.

Auch bei diesem Staubsauger kann mittels einer Umschalteinrichtung der Strömungsweg der angesaugten Luft zwischen dem Staubsaugermundstück 7 und dem an der Führungsstange 5 angekoppelten Saugmundstück umgeschaltet werden.In this vacuum cleaner, too, the flow path can be switched the sucked air between the vacuum cleaner mouthpiece 7 and the Guide rod 5 coupled suction mouthpiece can be switched.

Die in den Fig. 5 und 6 dargestellte Ausführungsvariante zeigt einen Staubsauger, bei dem das Staubsaugermundstück 7 wiederum um die Drehachse der Laufräder 2 verschwenkbar ist, wobei das Staubsaugermundstück 7 allerdings aus seiner Verschwenkverbindung mit den Laufrädern 2 gelöst werden kann. Das Staubsaugermundstück 7 kann somit von dem Staubsaugergehäuse 1 abgenommen werden. Die an dem Staubsaugermundstück 7 angesteckte, als Saugrohr dienende Führungsstange 5 ist ständig über einen Saugschlauch 8 mit einer Luftansaugöffnung 9 des Staubsaugergehäuses 1 verbunden. Damit ist stets der gleiche Strömungsweg gegeben egal ob das Staubsaugermundstück 7 an das Staubsaugergehäuse 1 angekoppelt ist oder ob dieses vom Staubsaugergehäuse 1 getrennt benutzt wird. Damit entfällt ein Umschalten des Strömungsweges. Es ist auch kein gesondertes Anstecken der Führungsstange 5 und des Saugschlauches 8 erforderlich. Das Staubsaugermundstück 7 wird lediglich aus seiner Schwenkverbindung mit dem Staubsaugergehäuse 1 gelöst und kann dann unmittelbar zur Durchführung spezieller Saugarbeiten verwendet werden. Solche speziellen Saugarbeiten können z.B. Eckenoder Kantensaugen oder auch Saugarbeiten an Decken oder Wänden sein.The embodiment shown in FIGS. 5 and 6 shows a vacuum cleaner, at which the vacuum cleaner mouthpiece 7 in turn around the axis of rotation of the impellers 2 is pivotable, but the vacuum cleaner mouthpiece 7 from his Pivot connection with the wheels 2 can be solved. The Vacuum cleaner mouthpiece 7 can thus be removed from the vacuum cleaner housing 1 become. The plugged into the vacuum cleaner mouthpiece 7, which serves as a suction pipe Guide rod 5 is always via a suction hose 8 with an air intake opening 9 of the vacuum cleaner housing 1 connected. This is always the same flow path given whether the vacuum cleaner mouthpiece 7 to the vacuum cleaner housing 1 is coupled or whether this is used separately from the vacuum cleaner housing 1. In order to there is no need to switch the flow path. It is also not a separate plug the guide rod 5 and the suction hose 8 required. The Vacuum cleaner mouthpiece 7 is only from its pivot connection with the Vacuum cleaner housing 1 solved and can then immediately carry out special Suction work can be used. Such special suction work can e.g. Or corner Edge suction or suction work on ceilings or walls.

Durch das an der Rückseite des Staubsaugergehäuses 1 angeordnete Abstützelement 4 erhält das Staubsaugergehäuse 1 eine stabile Lage.By means of the support element 4 arranged on the rear of the vacuum cleaner housing 1 the vacuum cleaner housing 1 receives a stable position.

Zur geordneten Aufbewahrung des Anschlusskabels des Staubsaugers ist an der Rückseite des Staubsaugergehäuses 1 eine Kabeltrommel 10 angebracht, auf der das Anschlusskabel während der Ruhezeit des Staubsaugers aufgewickelt ist. Zur Inbetriebnahme des Staubsaugers wird das Anschlusskabel in der erforderlichen Länge von der Kabeltrommel abgezogen.For orderly storage of the connection cable of the vacuum cleaner is on the Rear of the vacuum cleaner housing 1 attached a cable drum 10 on which Connection cable is wound up while the vacuum cleaner is idle. to Commissioning the vacuum cleaner, the connecting cable is of the required length pulled off the cable drum.
