Description

Die Erfindung betrifft eine Basisstation zum Reinigen und/oder Entleeren eines Saugerstaubraumes eines ersten Staubsaugers, welche Basisstation eine Basisstaubkammer, einen mit der Basisstaubkammer in Strömungsverbindung stehenden ersten Lufteintritt und einen mit der Basisstaubkammer in Strömungsverbindung stehenden ersten Luftaustritt aufweist, wobei der Lufteintritt und der Luftaustritt strömungstechnisch mit einem Luftkanal des ersten Staubsaugers verbindbar sind, so dass in dem Saugerstaubraum des ersten Staubsaugers enthaltener Staub mittels eines Gebläses des ersten Staubsaugers in die Basisstaubkammer förderbar ist.The invention relates to a base station for cleaning and / or emptying a suction dust chamber of a first vacuum cleaner, which base station has a base dust chamber, a first air inlet in fluid communication with the base dust chamber and a first air outlet in fluid communication with the base dust chamber, the air inlet and the air outlet fluidically can be connected to an air duct of the first vacuum cleaner, so that dust contained in the suction dust chamber of the first vacuum cleaner by means of a blower of the first vacuum cleaner is conveyed into the base dust chamber.

Basisstationen der vorgenannten Art sind im Stand der Technik hinreichend bekannt. Diese werden insbesondere in Kombination mit Staubsaugern verwendet, welche einen sogenannten Dauerfilter aufweisen, der bei vollständiger Füllung mit Staub nicht ersetzt wird, sondern mittels eines Spülluftstromes in eine der üblichen Saugrichtung entgegengesetzte Spülrichtung von Staub befreit wird. Zu diesem Zweck wird der Saugerstaubraum des Staubsaugers entweder an ein Gebläse der Basisstation angeschlossen oder mittels einer Strömungsumleitung an das eigene Gebläse des Staubsaugers.Base stations of the aforementioned type are well known in the art. These are used in particular in combination with vacuum cleaners which have a so-called permanent filter which is not replaced when completely filled with dust, but is freed of dust by means of a scavenging air flow in a direction opposite to the usual suction direction. For this purpose, the suction dust chamber of the vacuum cleaner is either connected to a blower of the base station or by means of a flow diversion to the fan of the vacuum cleaner own.

Die Druckschrift EP 1 243 218 B1 offenbart beispielsweise eine Basisstation zum Reinigen und/oder Entleeren eines Saugerstaubraumes, welche Basisstation eine Basisstaubkammer umfasst, in die der Schmutz/Staub aus dem Saugerstaubraum überführbar ist, wobei ein von dem eigenen Gebläse des zu reinigenden Staubsaugers erzeugter Saugluftstrom via der Basisstaubkammer in den Saugerstaubraum umlenkbar ist, wobei mittels des dadurch in der Basisstaubkammer entstehenden Unterdrucks der Schmutz aus dem Saugerstaubraum in die Basisstaubkammer einsaugbar ist.The publication EP 1 243 218 B1 For example, discloses a base station for cleaning and / or emptying a Saugstaubraumes, which base station comprises a base dust chamber into which the dirt / dust from the Saugerstaubraum can be transferred, wherein a generated by the own blower of the vacuum cleaner to be cleaned suction air flow via the base dust chamber in the Saugerstaubraum deflected is, by means of the resulting negative pressure in the base dust chamber, the dirt from the Saugerstaubraum in the base dust chamber is sucked.

Obwohl sich diese Art der Basisstation bewährt hat, ist diese jeweils nur zum Reinigen eines einzelnen Staubsaugers ausgebildet. Darüber hinaus steht limitierend nur das eigene Gebläse des Staubsaugers für die Reinigung zur Verfügung.Although this type of base station has proven itself, this is only designed to clean a single vacuum cleaner. In addition, only the own blower of the vacuum cleaner is available for cleaning.

Eine andere Basisstation ist ebenfalls in EP-A-2407074 offenbart. Es ist daher Aufgabe der Erfindung, eine Basisstation zu schaffen, an welcher mehrere Staubsauger gleichzeitig angeschlossen werden können. Vorteilhaft sollen die Staubsauger dabei zusätzlich an der Reinigung eines anderen Staubsaugers mitwirken können.Another base station is also in EP-A-2407074 disclosed. It is therefore an object of the invention to provide a base station to which a plurality of vacuum cleaners can be connected simultaneously. Advantageously, the vacuum cleaner should also participate in the cleaning of another vacuum cleaner.

Zur Lösung der Aufgabe schlägt die Erfindung vor, dass die Basisstation einen mit der Basisstaubkammer strömungstechnisch verbindbaren zweiten Lufteintritt und einen mit der Basisstaubkammer strömungstechnisch verbindbaren zweiten Luftaustritt aufweist, wobei der zweite Lufteintritt und der zweite Luftaustritt strömungstechnisch so mit einem Luftkanal eines zweiten Staubsaugers verbindbar sind, dass in einem Saugerstaubraum des zweiten Staubsaugers enthaltener Staub mittels des Gebläses des ersten Staubsaugers in die Basisstaubkammer förderbar ist.To achieve the object, the invention proposes that the base station has a second air inlet fluidically connectable to the base dust chamber and a second air outlet fluidically connectable to the base dust chamber, wherein the second air inlet and the second air outlet are fluidically connectable to an air duct of a second vacuum cleaner, in that dust contained in a suction dust chamber of the second vacuum cleaner can be conveyed into the base dust chamber by means of the blower of the first vacuum cleaner.

Dadurch wird eine passive Basisstation, d. h. eine Basisstation ohne eigenes Gebläse, geschaffen, welche zur Reinigung und/ oder Entleerung eines Saugerstaubraumes mehrerer gleichzeitig an die Basisstation angeschlossener Staubsauger dienen kann. Zu diesem Zweck stellt die Basisstation Lufteintritte und Luftaustritte für mehrere Staubsauger zur Verfügung, beispielsweise einen ersten Lufteintritt und ersten Luftaustritt für einen ersten Staubsauger, einen zweiten Lufteintritt und zweiten Luftaustritt für einen zweiten Staubsauger usw. Die Anzahl der Lufteintritte und Luftaustritte ist grundsätzlich nicht limitiert. Die Strömungsverbindungen zwischen der Basisstaubkammer und den Saugerstaubräumen der Staubsauger sind dabei so schaltbar, dass in Bezug auf beispielsweise einen ersten und einen zweiten angeschlossenen Staubsauger entweder der Saugerstaubraum des ersten Staubsaugers mittels des eigenen Gebläses des ersten Staubsaugers gereinigt wird oder dass der Saugerstaubraum des zweiten Staubsaugers mittels des Gebläses des ersten Staubsaugers gereinigt wird. Grundsätzlich ist es selbstverständlich auch möglich, dass der Saugerstaubraum des zweiten oder eines weiteren Staubsaugers mittels seines eigenen Gebläses gereinigt wird.As a result, a passive base station, ie a base station without its own fan, created, which can serve to clean and / or emptying a Saugstaubraumes several simultaneously connected to the base station vacuum cleaner. For this purpose, the base station provides air inlets and outlets for a plurality of vacuum cleaners, such as a first air inlet and first air outlet for a first vacuum cleaner, a second air inlet and second air outlet for a second vacuum cleaner, etc. The number of air inlets and outlets is generally not limited. The flow connections between the base dust chamber and the Saugerstaubräumen the vacuum cleaner are so switchable that is cleaned in terms of, for example, a first and a second vacuum cleaner connected either the Saugstaubraum the first vacuum cleaner by means of the fan of the first vacuum cleaner or that the Saugerstaubraum the second vacuum cleaner means the blower of the first vacuum cleaner is cleaned. Basically, it is also possible that the Suction dust chamber of the second or another vacuum cleaner is cleaned by means of its own blower.

Für eine Reinigung des Saugerstaubraumes des ersten Staubsaugers mittels seines eigenen Gebläses wird eine Strömungsverbindung zwischen dem ersten Staubsauger und der Basisstation in der Art geschaffen, dass das Gebläse des ersten Staubsaugers via des ersten Luftaustritts Luft aus der Basisstaubkammer der Basisstation ansaugt. Dabei strömt via des ersten Lufteintritts Luft aus dem Saugerstaubraum des ersten Staubsaugers in die Basisstaubkammer nach. Um einen geschlossenen Strömungskreislauf zu bilden, kann der Saugerstaubraum wiederum an das Gebläse des ersten Staubsaugers angeschlossen sein. Durch die so ausgebildete Strömungsverbindung gelangt in dem Saugerstaubraum des ersten Staubsaugers enthaltener Staub in die Basisstaubkammer und wird dort mittels eines in der Basisstaubkammer angeordneten Filterbeutels oder ähnlichem herausgefiltert, so dass die zu dem Gebläse strömende Luft von Staub befreit ist. Die Basisstaubkammer kann - beispielsweise bei vollständiger Belegung des Filters mit Staub - aus der Basisstation entfernt und geleert bzw. gereinigt werden. Insgesamt ist es somit nicht mehr erforderlich, dass der Staubsauger selbst einen herausnehmbaren Filter aufweist. Vielmehr kann der Luftfilter des Staubsaugers als Dauerfilter ausgebildet sein.For a cleaning of the suction dust chamber of the first vacuum cleaner by means of its own blower, a flow connection between the first vacuum cleaner and the base station is created in such a way that the blower of the first vacuum sucks air from the base dust chamber of the base station via the first air outlet. Air flows from the suction air space of the first vacuum cleaner into the base dust chamber via the first air inlet. In order to form a closed flow circuit, the suction dust space can in turn be connected to the blower of the first vacuum cleaner. Due to the flow connection thus formed, dust contained in the suction dust space of the first vacuum cleaner enters the base dust chamber and is filtered out there by means of a filter bag or the like arranged in the base dust chamber, so that the air flowing to the blower is freed from dust. The base dust chamber can be removed from the base station and emptied or cleaned, for example when the filter is completely covered with dust. Overall, it is thus no longer necessary that the vacuum cleaner itself has a removable filter. Rather, the air filter of the vacuum cleaner can be designed as a permanent filter.

Es wird vorgeschlagen, dass dem ersten Lufteintritt und dem zweiten Lufteintritt ein Ventil zugeordnet ist, welches ausgebildet ist, die Basisstaubkammer wahlweise mit dem Saugerstaubraum des ersten Staubsaugers oder dem Saugerstaubraum des zweiten Staubsaugers zu verbinden. Mittels des Ventils können somit diejenigen Strömungsverbindungen hergestellt werden, welche zur Reinigung/Entleerung des Saugerstaubraumes des ersten bzw. zweiten Staubsaugers notwendig sind. Dafür ist das Ventil an einer zentralen Stelle angeordnet, nämlich strömungstechnisch zwischen dem ersten Lufteintritt und dem zweiten Lufteintritt der Basisstation. Vorteilhaft ist das Ventil als Klappenventil ausgebildet, wobei grundsätzlich auch andere Bauformen des Ventils denkbar sind. Das Ventil stellt wahlweise entweder eine Verbindung zwischen der Basisstaubkammer und dem ersten Lufteintritt oder zwischen der Basisstaubkammer und dem zweiten Lufteintritt her. Sofern beispielsweise nur ein erster Staubsauger an die Basisstation angeschlossen ist, bleibt das Ventil in einer Stellung, in welcher der erste Lufteintritt mit der Basisstaubkammer verbunden ist und der zweite Lufteintritt von der Basisstaubkammer getrennt, so dass die Basisstaubkammer ausschließlich mit dem Saugerstaubraum des ersten Staubsaugers verbunden ist.It is proposed that the first air inlet and the second air inlet is associated with a valve which is adapted to selectively connect the base dust chamber with the suction dust chamber of the first vacuum cleaner or the suction dust chamber of the second vacuum cleaner. By means of the valve thus those flow connections can be made, which are necessary for cleaning / emptying of the suction dust chamber of the first and second vacuum cleaner. For this purpose, the valve is arranged at a central point, namely fluidically between the first air inlet and the second air inlet of the base station. Advantageously, the valve is designed as a flap valve, in principle, other designs of the valve are conceivable. The valve provides either a connection between the base dust chamber and the first air inlet or between the base dust chamber and the second air inlet ago. For example, if only a first vacuum cleaner is connected to the base station, the valve remains in a position in which the first air inlet is connected to the base dust chamber and the second air inlet is separated from the base dust chamber, so that the base dust chamber is connected exclusively to the suction dust chamber of the first vacuum cleaner is.

Ebenso empfiehlt es sich, dass dem ersten Luftaustritt und dem zweiten Luftaustritt ein Ventil zugeordnet ist, welches ausgebildet ist, das Gebläse des ersten Staubsaugers wahlweise mit dem Saugerstaubraum des ersten Staubsaugers oder dem Saugerstaubraum des zweiten Staubsaugers zu verbinden. Durch diese Ausgestaltung lässt sich das Ventil beispielsweise so schalten, dass entweder der Saugerstaubraum des ersten Staubsaugers oder der des zweiten Staubsaugers mittels des Gebläses des ersten Staubsaugers gereinigt wird. Für eine Reinigung des Saugerstaubraumes des zweiten Staubsaugers beispielsweise wird das zwischen dem ersten Luftaustritt und dem zweiten Luftaustritt angeordnete Ventil so geschaltet, dass der Saugerstaubraum des zweiten Staubsaugers mit dem Gebläse des ersten Staubsaugers in Strömungsverbindung steht. Durch diese Verbindung saugt das Gebläse des ersten Staubsaugers Staub aus dem Saugerstaubraum des zweiten Staubsaugers in die Basisstaubkammer der Basisstation. Das Ventil kann auch in diesem Fall ein Klappenventil oder ähnliches sein.Likewise, it is recommended that the first air outlet and the second air outlet is associated with a valve which is adapted to connect the blower of the first vacuum cleaner either with the Saugstaubraum the first vacuum cleaner or the Saugstaubraum the second vacuum cleaner. By means of this configuration, the valve can be switched, for example, so that either the suction dust chamber of the first vacuum cleaner or that of the second vacuum cleaner is cleaned by means of the blower of the first vacuum cleaner. For a cleaning of the suction dust chamber of the second vacuum cleaner, for example, the valve disposed between the first air outlet and the second air outlet is switched so that the vacuum cleaner chamber of the second vacuum cleaner is in flow communication with the blower of the first vacuum cleaner. Through this connection, the blower of the first vacuum sucks dust from the suction dust chamber of the second vacuum cleaner in the base dust chamber of the base station. The valve may also be a flap valve or the like in this case.

Des Weiteren wird vorgeschlagen, dass das Ventil eingerichtet ist, bei einem Anschluss des Luftkanals des zweiten Staubsaugers an den zweiten Lufteintritt und den zweiten Luftaustritt eine Strömungsverbindung zwischen dem Luftkanal des zweiten Staubsaugers und der Basisstaubkammer freizugeben. Gemäß dieser Ausgestaltung muss der Nutzer der Basisstation die Ventile im Bereich der Lufteintritte und Luftaustritte nicht manuell verstellen. Vielmehr werden die Ventile automatisch bei dem Anschluss eines zweiten Staubsaugers an die Basisstation so geschaltet, dass eine Strömungsverbindung zwischen dem zweiten Staubsauger und der Basisstation bzw. auch zu dem ersten Staubsauger gegeben ist.Furthermore, it is proposed that the valve is set up to release a flow connection between the air duct of the second vacuum cleaner and the base dust chamber when connecting the air duct of the second vacuum cleaner to the second air inlet and the second air outlet. According to this embodiment, the user of the base station does not have to manually adjust the valves in the area of the air inlets and air outlets. Rather, the valves are automatically switched to the connection of a second vacuum cleaner to the base station so that a flow connection between the second vacuum cleaner and the base station and also to the first vacuum cleaner is given.

Es wird vorgeschlagen, dass das Ventil beispielsweise durch mechanische Einwirkung eines Teilbereiches des zweiten Staubsaugers schaltbar ist. Der Teilbereich des zweiten Staubsaugers kann beispielsweise ein Saugkanalendbereich sein, welcher mechanisch auf das Ventil einwirkt. Die mechanische Einwirkung kann dabei sowohl das Ventil im Bereich der Lufteintritte als auch das Ventil im Bereich der Luftaustritte betreffen. Denkbar ist beispielsweise ein ausschließlich mechanisches Aufdrücken oder Aufstoßen einer Ventilklappe oder ähnliches.It is proposed that the valve is switchable, for example, by mechanical action of a portion of the second vacuum cleaner. The subregion of the second vacuum cleaner may be, for example, a Saugkanalendbereich which acts mechanically on the valve. The mechanical action can affect both the valve in the air inlet and the valve in the air outlet. It is conceivable, for example, an exclusively mechanical pressing or regurgitation of a valve flap or the like.

Darüber hinaus kann das Ventil mit einer elektromechanischen Ventilsteuerung verbunden sein, welche das Ventil in Abhängigkeit von einem Verbindungsstatus des zweiten Staubsaugers an dem zweiten Lufteintritt und/ oder dem zweiten Luftaustritt steuert. Die Ventilsteuerung umfasst dabei beispielsweise ein Sensorsystem, welches die Anordnung eines zweiten Staubsaugers an der Basisstation erkennt. In diesem Fall wird ein entsprechendes Schaltsignal an das Ventil oder die Ventile übermittelt. In diesem Sinne kann die Basisstation zum Beispiel elektrische Berührungskontakte aufweisen, welche eine insbesondere formkorrespondierende Anlage eines Teilbereiches des zweiten Staubsaugers an der Basisstation erkennen, so dass beispielsweise nicht nur darüber entschieden werden kann, ob ein zweiter Staubsauger an die Basisstation angeschlossen wurde, sondern auch, ob der zweite Staubsauger einem bestimmten Saugertyp entspricht, der von der Basisstation abgesaugt werden kann.In addition, the valve may be connected to an electromechanical valve control which controls the valve in response to a connection status of the second vacuum cleaner to the second air inlet and / or the second air outlet. The valve control includes, for example, a sensor system which detects the arrangement of a second vacuum cleaner to the base station. In this case, a corresponding switching signal is transmitted to the valve or the valves. In this sense, the base station may, for example, have electrical contacts which detect a particular shape corresponding installation of a portion of the second vacuum cleaner to the base station, so that, for example, not only can be decided whether a second vacuum cleaner has been connected to the base station, but also whether the second vacuum cleaner corresponds to a certain suction type, which can be sucked by the base station.

Die Basisstation kann ebenfalls ausgebildet sein, zwischen dem ersten Staubsauger und der Basisstation und/oder zwischen dem ersten Staubsauger und dem zweiten Staubsauger einen geschlossenen Strömungskreislauf herzustellen. Der geschlossene Strömungskreislauf wird dadurch ausgebildet, dass das Gebläse (Saugseite) des ersten Staubsaugers Luft aus der Basisstaubkammer bzw. dem daran angeschlossenen Saugerstaubraum des ersten oder zweiten Staubsaugers ansaugt, welcher Saugerstaubraum wiederum an das Gebläse (Druckseite) des ersten Staubsaugers angeschlossen ist.The base station may also be configured to establish a closed flow circuit between the first vacuum cleaner and the base station and / or between the first vacuum cleaner and the second vacuum cleaner. The closed flow circuit is formed by the fact that the fan (suction side) of the first vacuum sucks air from the base dust chamber or the attached Saugerstaubraum the first or second vacuum cleaner, which Saugerstaubraum is in turn connected to the fan (pressure side) of the first vacuum cleaner.

Um den Nutzen der Basisstation für den Nutzer zu steigern, wird ergänzend vorgeschlagen, dass die Basisstation ein elektrisches Ladegerät aufweist, welches mit einem Akkumulator des ersten Staubsaugers und/oder des zweiten Staubsaugers verbindbar ist. Somit können die an der Basisstation angeordneten Staubsauger nicht nur gereinigt/entleert werden, sondern zeitgleich auch in Bezug auf ihre Akkumulatoren aufgeladen werden. Der Nutzer muss den oder die Staubsauger somit nicht für mehrere aufeinanderfolgende Wartungsarbeiten entbehren, vielmehr werden verschiedene Wartungsaufgaben, nämlich Entleeren und Laden des Akkumulators, zeitgleich durchgeführt.In order to increase the usefulness of the base station for the user, it is additionally proposed that the base station has an electric charger which can be connected to an accumulator of the first vacuum cleaner and / or of the second vacuum cleaner. Thus, the vacuum cleaner arranged at the base station can not only be cleaned / emptied, but at the same time be charged with respect to their accumulators. The user does not need to dispense the vacuum cleaner or vacuum cleaners for several consecutive maintenance work, but rather various maintenance tasks, namely emptying and charging the battery, carried out at the same time.

Neben der zuvor dargestellten Basisstation wird mit der Erfindung ebenfalls ein Staubsaugersystem mit einer erfindungsgemäßen Basisstation, einem dazu korrespondierenden ersten Staubsauger und einem dazu ebenfalls korrespondierenden zweiten Staubsauger vorgeschlagen. Die Staubsauger korrespondieren mit der Basisstation in dem Sinne, dass sie kompatible Luftanschlüsse zueinander aufweisen. Das Staubsaugersystem kann beispielsweise als ersten Staubsauger einen Handstaubsauger aufweisen und als zweiten Staubsauger einen Saugroboter. Die Basisstation ist nach einer der zuvor erläuterten Ausführungsformen so ausgestaltet, dass die Luftkanäle der Staubsauger so an die Basisstaubkammer der Basisstation anschließbar sind, dass ein geschlossener Strömungskreislauf zwischen dem ersten Staubsauger und der Basisstation und zwischen dem ersten Staubsauger und dem zweiten Staubsauger hergestellt ist. Das Staubsaugersystem kann somit unterschiedliche Staubsauger reinigen, beispielsweise kann nur ein erster Staubsauger an die Basisstation angeschlossen sein, so dass nur dessen Saugerstaubraum mittels seines Gebläses geleert wird, oder es können sowohl ein erster als auch ein zweiter Staubsauger an die Basisstation angeschlossen sein, wobei auch der Saugerstaubraum des zweiten Staubsaugers durch das Gebläse des ersten Staubsaugers gereinigt wird. Selbstverständlich kann das Staubsaugersystem neben dem ersten und dem zweiten Staubsauger noch weitere Staubsauger aufweisen. Diese sind dann im Sinne der Erfindung ebenfalls als zweite Staubsauger definiert. Grundsätzlich kann selbstverständlich auch ein Saugerstaubraum eines zweiten Staubsaugers mittels des eigenen Gebläses des zweiten Staubsaugers gereinigt werden. Es handelt sich in dem Sinne dann um einen ersten Staubsauger.In addition to the base station described above, the invention also proposes a vacuum cleaner system with a base station according to the invention, a first vacuum cleaner corresponding thereto and a second vacuum cleaner likewise corresponding thereto. The vacuum cleaners correspond to the base station in the sense that they have compatible air connections to each other. The vacuum cleaner system, for example, as a first vacuum cleaner have a hand vacuum cleaner and a vacuum cleaner as the second vacuum cleaner. The base station according to one of the previously explained embodiments is configured such that the air ducts of the vacuum cleaner are connectable to the base dust chamber of the base station, that a closed flow circuit between the first vacuum cleaner and the base station and between the first vacuum cleaner and the second vacuum cleaner is made. The vacuum cleaner system can thus clean different vacuum cleaners, for example, only a first vacuum cleaner may be connected to the base station, so that only its Saugerstaubraum is emptied by means of its fan, or both a first and a second vacuum cleaner may be connected to the base station, also The suction dust chamber of the second vacuum cleaner is cleaned by the blower of the first vacuum cleaner. Of course, the vacuum cleaner system in addition to the first and the second vacuum cleaner still have more vacuum cleaners. These are then defined in the context of the invention also as a second vacuum cleaner. Basically, of course, a suction dust chamber of a second vacuum cleaner by means of the own blower of the second Vacuum cleaner to be cleaned. It is in the sense then a first vacuum cleaner.

Neben der Basisstation und dem Staubsaugersystem wird ebenfalls noch ein Verfahren zum Reinigen und/oder Entleeren eines Saugerstaubraumes eines zweiten Staubsaugers mittels eines erfindungsgemäßen Staubsaugersystems vorgeschlagen, wobei der erste Lufteintritt und der erste Luftaustritt der Basisstation an den Luftkanal des ersten Staubsaugers angeschlossen werden, und dass der zweite Lufteintritt und der zweite Luftaustritt der Basisstation an den Luftkanal des zweiten Staubsaugers angeschlossen werden, wobei anschließend in dem Saugerstaubraum des zweiten Staubsaugers enthaltener Staub mittels des Gebläses des ersten Staubsaugers in die Basisstaubkammer gefördert wird. Das erfindungsgemäße Verfahren ermöglicht es somit, den Saugerstaubraum eines zweiten Staubsaugers mittels des Gebläses eines ersten Staubsaugers zu reinigen. Vorteilhaft kann es sich bei dem ersten Staubsauger um einen handgeführten Staubsauger handeln und bei dem zweiten Staubsauger um einen Saugroboter, dessen Saugerstaubraum regelmäßig ein geringeres Volumen aufweist und somit häufiger zu reinigen ist.In addition to the base station and the vacuum cleaner system, a method for cleaning and / or emptying a vacuum cleaner room of a second vacuum cleaner by means of a vacuum cleaner system according to the invention is also proposed, wherein the first air inlet and the first air outlet of the base station are connected to the air duct of the first vacuum cleaner, and that second air inlet and the second air outlet of the base station to be connected to the air duct of the second vacuum cleaner, wherein subsequently in the suction dust chamber of the second vacuum cleaner dust is conveyed by means of the blower of the first vacuum cleaner in the base dust chamber. The inventive method thus makes it possible to clean the suction dust chamber of a second vacuum cleaner by means of the blower of a first vacuum cleaner. Advantageously, the first vacuum cleaner may be a hand-held vacuum cleaner, and the second vacuum cleaner may be a vacuum cleaner, the suction dust chamber of which has a smaller volume on a regular basis and is thus more frequently cleaned.

Figur 1 zeigt ein Staubsaugersystem 19 bestehend aus einer Basisstation 1, einem ersten Staubsauger 3 und einem zweiten Staubsauger 4. Der erste Staubsauger 3 ist beispielsweise ein handgeführter Akkusauger, während der zweite Staubsauger beispielsweise ein selbstverfahrender Reinigungsroboter ist. Die Basisstation 1 weist ein Gehäuse auf, in welches zumindest Teilbereiche des ersten und zweiten Staubsaugers 3, 4 formschlüssig aufgenommen werden können, so dass insgesamt eine kleinstmögliche Bauform des Staubsaugersystems 19 in zusammengesetztem Zustand erreicht wird. FIG. 1 shows a vacuum cleaner system 19 consisting of a base station 1, a first vacuum cleaner 3 and a second vacuum cleaner 4. The first vacuum cleaner 3, for example, a hand-held vacuum cleaner, while the second vacuum cleaner is, for example, a self-propelled cleaning robot. The base station 1 has a housing, in which at least partial areas of the first and second vacuum cleaners 3, 4 can be received in a form-fitting manner, so that a total of the smallest possible design of the vacuum cleaner system 19 is achieved in the assembled state.

Die Figur 2 zeigt den mit der Basisstation 1 verbundenen ersten Staubsauger 3, wobei dieser formschlüssig in Teilbereiche des Gehäuses der Basisstation 1 aufgenommen ist.The FIG. 2 shows the first vacuum cleaner 3 connected to the base station 1, wherein the latter is received in a form-fitting manner in partial areas of the housing of the base station 1.

Die Figur 3 zeigt die Basisstation 1 mit dem daran angeschlossenen ersten und zweiten Staubsauger 3, 4, wobei der zweite Staubsauger 4 selbsttätig unter einen korrespondierenden Teilbereich der Basisstation 1 gefahren ist.The FIG. 3 shows the base station 1 with the connected first and second vacuum cleaner 3, 4, wherein the second vacuum cleaner 4 is driven automatically under a corresponding portion of the base station 1.

Gemäß den Figuren 1 bis 3 weisen sowohl der erste Staubsauger 3 als auch der zweite Staubsauger 4 Saugöffnungen 17 und Ausblasöffnungen 18 auf, wobei die Saugöffnungen 17 zum Einsaugen von Staub in einen Saugerstaubraum 5, 6 des Staubsaugers 3, 4 dienen und die Auslassöffnungen 18 zum Ausblasen von mittels eines Luftfilters 16 gereinigter Luft aus dem Staubsauger 3, 4 dienen.According to the FIGS. 1 to 3 Both the first vacuum cleaner 3 and the second vacuum cleaner 4 suction openings 17 and exhaust openings 18, wherein the suction openings 17 for sucking dust into a suction dust chamber 5, 6 of the vacuum cleaner 3, 4 serve and the outlet openings 18 for blowing out by means of an air filter 16th cleaned air from the vacuum cleaner 3, 4 serve.

Figur 4 zeigt ein erstes Ausführungsbeispiel der Erfindung, bei welchem nur ein erster Staubsauger 3 an die Basisstation 1 angeschlossen ist. Die schematische Querschnittsansicht zeigt, dass die Basisstation 1 eine Basisstaubkammer 2 aufweist, sowie einen ersten Lufteintritt 7 und einen ersten Luftaustritt 8, welche strömungstechnisch mit der Basisstaubkammer 2 verbunden sind und Anschlüsse für den ersten Staubsauger 3 zur Verfügung stellen. In der Basisstaubkammer 2 ist vorteilhaft ein Filterbeutel angeordnet, in welchem der in den Saugerstaubraum 5 gelangende Staub gesammelt werden kann. Neben dem ersten Lufteintritt 7 und dem ersten Luftaustritt 8 weist die Basisstation 1 zusätzlich einen zweiten Lufteintritt 12 und einen zweiten Luftaustritt 13 auf, welche zum Anschluss an einen zweiten Staubsauger 4 dienen. In dem Strömungsweg zwischen dem ersten Lufteintritt 7 und dem zweiten Lufteintritt 12 sowie zwischen dem ersten Luftaustritt 8 und dem zweiten Luftaustritt 13 ist jeweils ein Ventil 14,15 angeordnet, welches von einer ersten Stellung in eine zweite Stellung verschwenkbar ist, wenn ein zweiter Staubsauger 4 an die Basisstation 1 angeschlossen ist und gereinigt werden soll. FIG. 4 shows a first embodiment of the invention, in which only a first vacuum cleaner 3 is connected to the base station 1. The schematic cross-sectional view shows that the base station 1 has a base dust chamber 2, and a first air inlet 7 and a first air outlet 8, which are fluidically connected to the base dust chamber 2 and provide connections for the first vacuum cleaner 3 available. In the base dust chamber 2, a filter bag is advantageously arranged, in which the reaching into the suction dust chamber 5 dust can be collected. In addition to the first air inlet 7 and the first air outlet 8, the base station 1 additionally has a second air inlet 12 and a second air outlet 13, which serve for connection to a second vacuum cleaner 4. In the flow path between the first air inlet 7 and the second air inlet 12 and between the first air outlet 8 and the second air outlet 13, a valve 14,15 is in each case arranged, which is pivotable from a first position to a second position when a second vacuum cleaner. 4 is connected to the base station 1 and should be cleaned.

Der erste Staubsauger 3 ist mittels seiner Saugöffnung 17, der Auslassöffnung 18 und einer zusätzlichen Reinigungsöffnung 21 an die Strömungswege der Basisstation 1 angeschlossen. Darüber hinaus verfügt der erste Staubsauger 13 über einen Saugerstaubraum 5, in welchen ein Luftfilter 16, hier ein Dauerfilter, eingesetzt ist. Der Saugerstaubraum 5 ist mittels eines Luftkanals 9 mit einem Gebläse 11 des ersten Staubsaugers 3 verbunden, welches während eines üblichen Saugbetriebs des ersten Staubsaugers 3 Luft von der Saugöffnung 17 durch den Luftfilter 16 zu dem Gebläse 11 fördert. Dabei gelangt in der angesaugten Luft enthaltener Staub in den Luftfilter 16 und wird in dem Saugerstaubraum 5 gesammelt. Somit strömt ausschließlich von Staub gereinigte Luft zu dem Gebläse 11 und aus der Auslassöffnung 18 heraus.The first vacuum cleaner 3 is connected by means of its suction opening 17, the outlet opening 18 and an additional cleaning opening 21 to the flow paths of the base station 1. In addition, the first vacuum cleaner 13 has a suction dust chamber 5, in which an air filter 16, here a permanent filter, is used. The suction dust chamber 5 is connected by means of an air channel 9 with a blower 11 of the first vacuum cleaner 3, which promotes 3 air from the suction port 17 through the air filter 16 to the blower 11 during a conventional suction operation of the first vacuum cleaner. In this case, dust contained in the sucked air enters the air filter 16 and is collected in the suction dust chamber 5. Thus, only dust-purified air flows out to the blower 11 and out the discharge port 18.

Die Basisstaubkammer 2 ist auch über eine Anschlussleitung 22 mit dem Luftkanal 9 verbunden. Mittels des Gebläses 11 kann hierüber ein Unterdruck in der Basisstaubkammer 2 erzeugt werden. Die Anschlussleitung 22 kreuzt auch eine die Auslassöffnung 18 mit dem ersten Luftaustritt 8 verbindende Verbindungsleitung 23 (wenn sich das Ventil 15 in der Stellung gemäß Figur 4 befindet). Hierbei ist jedoch zwischen der Anschlussleitung 22 und der Verbindungsleitung 23 keine strömungsmäßige Verbindung gegeben.The base dust chamber 2 is also connected via a connecting line 22 to the air duct 9. By means of the blower 11, a negative pressure in the base dust chamber 2 can be generated via this. The connecting line 22 also crosses a connecting line 23 connecting the outlet opening 18 with the first air outlet 8 (when the valve 15 is in the position according to FIG FIG. 4 located). However, this is between the connecting line 22 and the connecting line 23 is given no fluid connection.

In dem beispielhaft dargestellten Reinigungsmodus des ersten Staubsaugers 3 ist die Auslassöffnung 18 des ersten Staubsaugers 3 mit dem ersten Luftaustritt 8 der Basisstation 1 verbunden, während die Saugöffnung 17 des ersten Staubsaugers 3 mit dem ersten Lufteintritt 7 der Basisstation 1 in Strömungsverbindung steht. Der zweite Lufteintritt 12 und der zweite Luftaustritt 13 der Basisstation 1 sind durch die Ventile 14,15 verschlossen, so dass keine Umgebungsluft durch den zweiten Lufteintritt 12 bzw. zweiten Luftaustritt 13 in die Basisstation 1 bzw. den ersten Staubsauger 3 gelangen kann.In the exemplified cleaning mode of the first vacuum cleaner 3, the outlet opening 18 of the first vacuum cleaner 3 is connected to the first air outlet 8 of the base station 1, while the suction opening 17 of the first vacuum cleaner 3 is in fluid communication with the first air inlet 7 of the base station 1. The second air inlet 12 and the second air outlet 13 of the base station 1 are closed by the valves 14, 15, so that no ambient air can reach the base station 1 or the first vacuum cleaner 3 through the second air inlet 12 or second air outlet 13.

Die Reinigung des ersten Staubsaugers 3 kann manuell durch den Nutzer gestartet werden oder alternativ automatisch, wenn beispielsweise ein an der Basisstation 1 angeordneter Sensor (nicht dargestellt) erkennt, dass ein erster Staubsauger 3 mit der Basisstation 1 verbunden wurde. Sodann wird das Gebläse 11 gestartet und ein in dem Luftkanal 9 des ersten Staubsaugers 3 angeordnetes Saugerventil 20 geschlossen, so dass der Luftkanal 9 strömungstechnisch unterbrochen ist und das Gebläse 11 keine direkte Strömungsverbindung mehr zu dem Saugerstaubraum 5 aufweist. Die von dem Gebläse 11 geförderte Luft strömt durch die Auslassöffnung 18 des ersten Staubsaugers 3 und gelangt durch einen in der Basisstation 1 ausgebildeten Strömungskanal in den Saugerstaubraum 5, wobei die Luft dem Luftfilter 16 von innen zugeführt wird, so dass dieser entgegen der üblichen Strömungsrichtung für einen Saugbetrieb des ersten Staubsaugers 3 durchströmt wird. Der außen an dem Luftfilter 16 abgelagerte Staub und Schmutz wird von der von innen nach außen strömenden Luft mitgerissen und gelangt durch die Saugöffnung 17 des ersten Staubsaugers 3 zu dem ersten Lufteintritt 7 der Basisstation 1. Von dort aus gelangt die staubbeladene Luft anschließend in die Basisstaubkammer 2, wird von einem in der Basisstaubkammer 2 angeordneten Filter, beispielsweise Filtertüte, gefiltert und strömt als gereinigte Luft aus der Basisstaubkammer 2 zurück zu dem Gebläse 11 des ersten Staubsaugers 3. Damit ist der Strömungskreislauf geschlossen.The cleaning of the first vacuum cleaner 3 can be started manually by the user or, alternatively, automatically if, for example, a sensor (not shown) arranged on the base station 1 recognizes that a first vacuum cleaner 3 has been connected to the base station 1. Then, the blower 11 is started and arranged in the air duct 9 of the first vacuum cleaner 3 suction valve 20 is closed, so that the air duct 9 is fluidically interrupted and the fan 11 has no direct flow connection to the Saugerstaubraum 5. The air conveyed by the blower 11 flows through the outlet opening 18 of the first vacuum cleaner 3 and passes through a formed in the base station 1 flow channel in the suction dust chamber 5, wherein the air is supplied to the air filter 16 from the inside, so that this contrary to the usual flow direction for a suction operation of the first vacuum cleaner 3 is flowed through. The dust and dirt deposited on the outside of the air filter 16 are entrained by the air flowing in from inside to outside and pass through the suction opening 17 of the first vacuum cleaner 3 to the first air inlet 7 of the base station 1. From there, the dust-laden air subsequently enters the base dust chamber 2, is filtered by a arranged in the base dust chamber 2 filter, such as filter bag, and flows as purified air from the base dust chamber 2 back to the blower 11 of the first vacuum cleaner 3. Thus, the flow loop is closed.

Figur 5 zeigt ein zweites Ausführungsbeispiel der Erfindung, bei welchem sowohl ein erster Staubsauger 3 als auch ein zweiter Staubsauger 4 an die Basisstation 1 angeschlossen 1. Der erste Staubsauger 3 ist wie gemäß Figur 4 erläutert an die Basisstation 1 angeschlossen. Zusätzlich sind der zweite Lufteintritt 12 und der zweite Luftaustritt 13 der Basisstation 1 nun mit Luftanschlüssen des zweiten Staubsaugers 4, hier dem Saugroboter, verbunden. FIG. 5 shows a second embodiment of the invention, in which both a first vacuum cleaner 3 and a second vacuum cleaner 4 connected to the base station 1. The first vacuum cleaner 3 is as in accordance with FIG. 4 explained connected to the base station 1. In addition, the second air inlet 12 and the second air outlet 13 of the base station 1 are now connected to air connections of the second vacuum cleaner 4, in this case the vacuum robot.

Der zweite Staubsauger 4 weist ebenfalls einen Saugerstaubraum 6 mit einem Luftfilter 16 sowie ein Gebläse 11 auf. Der Saugerstaubraum 6 und das Gebläse 11 sind über einen Luftkanal 10 miteinander verbunden.The second vacuum cleaner 4 also has a suction dust chamber 6 with an air filter 16 and a fan 11. The suction dust chamber 6 and the blower 11 are connected to each other via an air duct 10.

Die Basisstation 1 kann eine Sensorik (nicht dargestellt) aufweisen, welche die Präsenz des zweiten Staubsaugers 4 an dem zweiten Lufteintritt 12 und dem zweiten Luftaustritt 13 erkennt, beispielsweise einen Berührungssensor. Eine Ventilsteuerung (nicht dargestellt) kann die Ventile 14,15 so steuern, dass der Saugkanal 10 des zweiten Staubsaugers 4 strömungstechnisch an die Basisstaubkammer 2 und das Gebläse 11 des ersten Staubsauger 3, angeschlossen wird. Das Ventil 14 wird so geschaltet, dass eine Strömungsverbindung zwischen dem zweiten Lufteintritt 12 und der Basisstaubkammer 2 besteht. Das Ventil 15 wird entsprechend so geschaltet, dass eine Strömungsverbindung zwischen dem zweiten Luftaustritt 13 und dem Gebläse 11 des ersten Staubsaugers 3 besteht. Vorteilhaft wird ebenfalls das Saugerventil 20 innerhalb des Luftkanals 9 des ersten Staubsaugers 3 automatisch geschlossen.The base station 1 may have a sensor system (not shown) which detects the presence of the second vacuum cleaner 4 at the second air inlet 12 and the second air outlet 13, for example a touch sensor. A valve control (not shown) may control the valves 14,15 so that the suction channel 10 of the second vacuum cleaner 4 is fluidly connected to the base dust chamber 2 and the blower 11 of the first vacuum cleaner 3. The valve 14 is switched so that there is a flow connection between the second air inlet 12 and the base dust chamber 2. The valve 15 is correspondingly switched so that there is a flow connection between the second air outlet 13 and the blower 11 of the first vacuum cleaner 3. Advantageously, the suction valve 20 is automatically closed within the air duct 9 of the first vacuum cleaner 3.

Für eine Reinigung bzw. Entleerung des Saugerstaubraumes 6 des zweiten Staubsaugers 4 wird das Gebläse 11 des ersten Staubsaugers 3 gestartet. Durch die entsprechend geschalteten Ventile 14,15 sowie das Saugerventil 20 ist ein geschlossener Strömungskreislauf zwischen dem Gebläse 11 des ersten Staubsaugers 3, der Auslassöffnung 18 des ersten Staubsaugers 3, dem zweiten Luftaustritt 13 der Basisstation 1, dem Luftkanal 10 des zweiten Staubsaugers 4, dem zweiten Lufteintritt 12 der Basisstation 1, der Basisstaubkammer 2 und schließlich wieder dem Gebläse 11 des ersten Staubsaugers 3 hergestellt. Insofern wirken das Gebläse 11 des ersten Staubsaugers 3 und der Saugerstaubraum 6 des zweiten Staubsaugers 4 so zusammen, dass in dem Saugerstaubraum 6 des zweiten Staubsaugers 4 enthaltener Staub mittels des Gebläses 11 des ersten Staubsaugers 3 in die Basisstaubkammer 2 der Basisstation 1 gefördert wird, wo der gesammelte Staub schließlich entsorgt werden kann. Die Basisstation 1 selbst benötigt kein eigenes Gebläse, da sowohl für die Reinigung des Saugerstaubraums 5 des ersten Staubsaugers 3 als auch für die Reinigung des Saugerstaubraums 6 des zweiten Staubsaugers 4 jeweils nur das Gebläse 11 des ersten Staubsaugers 3 verwendet wird.For cleaning or emptying of the suction dust chamber 6 of the second vacuum cleaner 4, the blower 11 of the first vacuum cleaner 3 is started. By the correspondingly switched valves 14,15 and the suction valve 20 is a closed flow circuit between the blower 11 of the first vacuum cleaner 3, the outlet port 18 of the first vacuum cleaner 3, the second air outlet 13 of the base station 1, the air duct 10 of the second vacuum cleaner 4, the second air inlet 12 of the base station 1, the base dust chamber 2 and finally the blower 11 of the first vacuum cleaner 3 again. In this respect, the blower 11 of the first vacuum cleaner act 3 and the suction dust chamber 6 of the second vacuum cleaner 4 together so that dust contained in the suction dust chamber 6 of the second vacuum cleaner 4 is conveyed by means of the blower 11 of the first vacuum cleaner 3 into the base dust chamber 2 of the base station 1, where the collected dust can be finally disposed of. The base station 1 itself does not require its own blower, since only the blower 11 of the first vacuum cleaner 3 is used both for the cleaning of the suction dust chamber 5 of the first vacuum cleaner 3 and for the cleaning of the suction dust chamber 6 of the second vacuum cleaner 4.

Neben den gezeigten Ausführungsbeispielen sind selbstverständlich Variationen möglich, welche beispielsweise eine andere Form des Schaltens der Ventile 14,15, 20 eine andere Art der Ventile 14, 15, 20 oder andere örtliche Positionen der Lufteintritte 7, 12 und Luftaustritte 8, 13 innerhalb der Basisstation 1 vorsehen. Darüber hinaus kann die Basisstation 1 durch manuelle oder elektromechanische Ventilsteuerungen ergänzt werden oder ähnliches. Die gezeigten Ausführungsbeispiele sind insofern keineswegs beschränkend.In addition to the embodiments shown, of course, variations are possible, such as another form of switching the valves 14,15, 20 another type of valves 14, 15, 20 or other local positions of the air inlets 7, 12 and air outlets 8, 13 within the base station Provide 1. In addition, the base station 1 can be supplemented by manual or electromechanical valve controls or the like. The embodiments shown are far from limiting.
