Stand der TechnikState of the art

Reinigungsgeräte der vorgenannten Art sind im Stand der Technik hinreichend bekannt. Diese sind beispielsweise als Feuchtwischgeräte ausgebildet, deren Reinigungswalze einen Flüssigkeit aufnehmenden Walzenbelag aufweist.Cleaning devices of the aforementioned type are well known in the art. These are, for example, designed as wet wiping devices, the cleaning roller has a liquid receiving roll surface.

Die Druckschrift DE 102 29 611 B3 offenbart beispielsweise ein Reinigungsgerät mit einer befeuchteten Reinigungswalze, welche während eines Reinigungsvorgangs Schmutz von einer zu reinigenden Fläche aufnimmt. Anschließend wird die Reinigungswalze während eines Regenerationsprozesses mit einer gegenüber dem Reinigungsvorgang erhöhten Drehzahl rotiert, so dass die verschmutzte Flüssigkeit aus der Reinigungswalze ausgetrieben wird.The publication DE 102 29 611 B3 discloses, for example, a cleaning device with a moistened cleaning roller which receives dirt from a surface to be cleaned during a cleaning process. Subsequently, the cleaning roller is rotated during a regeneration process at a higher speed compared to the cleaning process, so that the contaminated liquid is expelled from the cleaning roller.

Für das Abschleudern des Schmutzwassers von der Reinigungswalze kann die Drehzahl der Reinigungswalze einstellbar sein. Dazu ist üblicherweise ein umschaltbares Gerätegetriebe erforderlich, welches die Drehzahl der Reinigungswalze während des Reinigungsvorgangs bzw. des Regenerationsvorgangs ändert.For the centrifuging of the dirty water from the cleaning roller, the speed of the cleaning roller can be adjustable. For this purpose, a switchable gear unit is usually required, which changes the rotational speed of the cleaning roller during the cleaning process or the regeneration process.

Nachteilig sind dabei der relativ hohe Platzbedarf und das Gewicht des Getriebes, welche auch die Größe und das Gewicht des Reinigungsgerätes negativ beeinflussen.Disadvantages are the relatively high space requirements and the weight of the transmission, which also adversely affect the size and weight of the cleaning device.

Aus der DE 102008018511 A1 ist ein Reinigungsgerät bekannt, bei welchem die Reinigungsbürsten entweder selbst nicht angetrieben sind oder aber zur Regeneration ohne antriebsmäßige Zuhilfenahme der Basisstation angetrieben werden. Soweit die Reinigungswalzen mit Hilfe der Basisstation zur Regeneration angetrieben werden, werden hierzu die in der Basisstation vorgesehenen Elektromotoren genutzt. Diese Elektromotoren wirken dann unmittelbar über die Antriebszahnräder mit den Abtriebszahnrädern der Reinigungsbürsten zusammen.From the DE 102008018511 A1 a cleaning device is known in which the cleaning brushes are either not driven by themselves or are driven for regeneration without driving assistance of the base station.

Die Bürste kann zum Austrieb von Reinigungsflüssigkeit mit dem Elektromotor drehangetrieben werden.From the DE 10229611 B3 is a cleaning device known with a rotary drivable brush.

By means of the external gear, the speed of the cleaning roller is increased so that dirt can be thrown off optimally by the cleaning roller.

Gemäß der Erfindung ist das Reinigungsgerät zur Interaktion mit einem externen Getriebe, beispielsweise einem Getriebe einer Basisstation, ausgebildet, wobei das Getriebe der Basisstation so mit dem Motor und der Reinigungswalze des Reinigungsgerätes koppelbar ist, dass der Antrieb der Reinigungswalze während eines Reinigungsvorgangs wie üblich mittels des Gerätegetriebes erfolgt und während eines Regenerationsvorgangs wie üblich mittels des Basisstationsgetriebes. Somit kann das externe Getriebe, welches zur Bereitstellung einer für die Regeneration der Reinigungswalze erforderlichen Drehzahl geeignet ist, beispielsweise in eine Basisstation integriert sein, so dass das Reinigungsgerät selbst kein zusätzliches Getriebe und auch kein umschaltbares Getriebe mit mehreren Getriebestufen aufweisen muss. Das Reinigungsgerät kann somit kostengünstig hergestellt werden.According to the invention, the cleaning device is designed to interact with an external transmission, for example a transmission of a base station, wherein the transmission of the base station can be coupled to the motor and the cleaning roller of the cleaning device, that the drive of the cleaning roller during a cleaning operation as usual by means of Gearbox takes place and during a regeneration process as usual by means of the base station transmission. Thus, the external gear, which is suitable for providing a required for the regeneration of the cleaning roller speed, for example, be integrated into a base station, so that the cleaning device itself must have no additional gear and also no switchable gearbox with multiple gear stages. The cleaning device can thus be manufactured inexpensively.

Die Reinigungswalze des Reinigungsgerätes kann während eines Reinigungsvorgangs mit einer ersten Drehzahl rotieren, und während eines Regenerationsvorgangs mit einer zweiten Drehzahl. Beispielsweise kann das Gerätegetriebe ein Übersetzungsverhältnis von 20:1 aufweisen, während das Basisstationsgetriebe ein Übersetzungsverhältnis von 1:20 aufweist. Bei einer Hintereinanderschaltung des Gerätegetriebes und des externen Getriebes entspricht die Drehzahl während des Regenerationsvorgangs somit der Motordrehzahl. Während des Reinigungsvorgangs entspricht die Drehzahl der Reinigungswalze hingegen einem Zwanzigstel der Motordrehzahl. Bei einer Motordrehzahl von beispielsweise 6.000 U/min beträgt die Abtriebsdrehzahl des Gerätegetriebes 300 U/min, was für die Reinigung einer Fläche vorteilhaft ist. Für den Regenerationsvorgang wird diese Abtriebsdrehzahl des Gerätegetriebes von 300 U/ min mittels des nachgeschalteten Basisstationsgetriebes wieder erhöht, nämlich mit einem Übersetzungsverhältnis von 1:20 auf eine Drehzahl von 6.000 U/min, was hier der Drehzahl des Motors entspricht. Die Leistung des Motors bleibt dabei im Wesentlichen gleich, da die Rotation der Reinigungswalze während des Reinigungsvorgangs ein hohes Drehmoment und eine niedrige Drehzahl erfordert, während die Rotation der Reinigungswalze während des Regenerationsvorgangs ein niedriges Drehmoment und eine hohe Drehzahl erfordert. Beide Vorgänge, d. h. sowohl Reinigung als auch Regeneration, können somit mit demselben Motor durchgeführt werden. Der Getriebemotor kann gemäß der Erfindung somit nur eine einzige Drehzahl aufweisen, wenngleich es auch nicht ausgeschlossen ist, dass der Motor mehrere unterschiedliche Drehzahlen aufweist.The cleaning roller of the cleaning device may rotate at a first speed during a cleaning operation, and at a second speed during a regeneration operation. For example, the gearbox may have a gear ratio of 20: 1, while the base station gearbox has a gear ratio of 1:20. In a series connection of the gear unit and the external transmission, the speed during the regeneration process thus corresponds to the engine speed. During the cleaning process, however, the speed of the cleaning roller corresponds to one twentieth of the engine speed. At an engine speed of, for example, 6,000 rpm, the output speed of the gearbox is 300 rpm, which is advantageous for cleaning a surface. For the regeneration process, this output speed of the gear unit of 300 U / min is increased again by means of the downstream base station transmission, namely with a gear ratio of 1:20 to a speed of 6,000 rpm, which here corresponds to the speed of the motor. The power of the motor remains essentially the same because the rotation of the cleaning roller during the cleaning process requires a high torque and a low speed, while the rotation of the cleaning roller during the regeneration process requires a low torque and high speed. Both processes, d. H. both cleaning and regeneration can thus be carried out with the same engine. The geared motor can thus according to the invention thus have only a single speed, although it is not excluded that the engine has several different speeds.

Durch die Rotation der Reinigungswalze mit entgegen dem üblichen Reinigungsvorgang erhöhter Drehzahl kann der an der Reinigungswalze haftende Schmutz effektiv abgeschleudert werden. Vorteilhaft weist eine mit dem Reinigungsgerät verbindbare Basisstation einen die Reinigungswalze zumindest teilweise umgebenden Auffangbehälter auf, in welchem der von der rotierenden Reinigungswalze weggeschleuderte Schmutz aufgefangen wird.By rotating the cleaning roller with contrary to the usual cleaning process increased speed of the adhering to the cleaning roller dirt can be effectively thrown off. Advantageously, a base station which can be connected to the cleaning device has a collecting container which at least partially surrounds the cleaning roller and in which the dirt thrown away by the rotating cleaning roller is collected.

Des Weiteren wird vorgeschlagen, dass zwischen der Reinigungswalze und dem Motor ein Freilauf ausgebildet ist. Der Antriebstrang des Reinigungsgerätes beinhaltet somit neben dem Motor und dem Gerätegetriebe einen Freilauf, welcher das Gerätegetriebe entweder kraftübertragend mit der Reinigungswalze verbindet oder das Gerätegetriebe von der Reinigungswalze trennt. Der Freilauf ist dabei in einer besonders einfachen Art und Weise als Rutschkupplung ausgebildet, welche in einer ersten Drehrichtung eine kraftübertragende Verbindung herstellt und in einer zweiten, entgegengesetzten Drehrichtung eine Verbindung verhindert. Dabei überbrückt eine zu dem Antriebsstrang des Reinigungsgerätes parallele Verbindung, welche das externe Getriebe aufweist, den Freilauf und die Reinigungswalze, so dass bei aktiviertem Freilauf der Motor bzw. das Gerätegetriebe des Reinigungsgerätes über das externe Getriebe mit der Reinigungswalze verbunden werden kann. Erfindungsgemäß ist somit durch einen Wechsel der Drehrichtung des Freilaufes ein Wechsel zwischen der Drehzahl des externen Getriebes und der Drehzahl des Gerätegetriebes möglich.Furthermore, it is proposed that a freewheel is formed between the cleaning roller and the motor. The drive train of the cleaning device thus includes in addition to the engine and the gearbox a freewheel, which connects the gearbox either force-transmitting with the cleaning roller or separates the gearbox from the cleaning roller. The freewheel is designed in a particularly simple manner as a slip clutch, which produces a force-transmitting connection in a first direction of rotation and prevents a connection in a second, opposite direction of rotation. In this case, a parallel to the drive train of the cleaning device connection, which has the external transmission, the freewheel and the cleaning roller, so that when activated freewheel, the engine or the gearbox of the cleaning device can be connected via the external transmission with the cleaning roller. According to the invention is thus by changing the direction of the Freewheeling a change between the speed of the external gear and the speed of the gearbox possible.

Es wird vorgeschlagen, dass der Freilauf ausgebildet ist, den Motor ohne Beteiligung der Geräteschnittstelle in einer ersten Drehrichtung mit der Reinigungswalze zu koppeln und in einer zweiten Drehrichtung von der Reinigungswalze zu entkoppeln. Somit dient der Motor des Reinigungsgerätes nicht nur zum Antrieb der Reinigungswalze, sondern vielmehr auch zur drehrichtungsabhängigen Verbindung der Reinigungswalze mit entweder dem Gerätegetriebe oder dem externen Getriebe, wobei durch die Wahl des Getriebes gleichzeitig auch die Drehzahl der Rotationswalze bestimmt wird.It is proposed that the freewheel is designed to couple the motor with the cleaning roller in a first rotational direction without involvement of the device interface and to decouple it from the cleaning roller in a second rotational direction. Thus, the motor of the cleaning device is not only used to drive the cleaning roller, but also to the direction of rotation dependent connection of the cleaning roller with either the gearbox or the external gear, which is determined by the choice of the gear at the same time the rotational speed of the rotating roller.

Neben dem zuvor erläuterten Reinigungsgerät wird mit der Erfindung ebenso auch eine Basisstation für ein Reinigungsgerät vorgeschlagen, welche eine Basisstationsschnittstelle und ein Basisstationsgetriebe aufweist, wobei das Basisstationsgetriebe mittels der Basisstationsschnittstelle kraftübertragend mit einem Motor und einer Reinigungswalze eines Reinigungsgerätes verbindbar ist.In addition to the above-described cleaning device, the invention also proposes a base station for a cleaning device, which has a base station interface and a base station transmission, wherein the base station transmission by means of the base station interface force-transmitting with a motor and a cleaning roller of a cleaning device is connectable.

Des Weiteren wird auch ein System aus einem Reinigungsgerät und einer Basisstation vorgeschlagen, insbesondere einem zuvor beschriebenen erfindungsgemäßen Reinigungsgerät und einer zuvor beschriebenen erfindungsgemäßen Basisstation, wobei das Reinigungsgerät eine um eine Drehachse rotierbare Reinigungswalze, einen die Reinigungswalze antreibenden Motor und ein zwischen der Reinigungswalze und dem Motor angeordnetes Gerätegetriebe aufweist, wobei die Reinigungswalze mittels des Motors rotierbar ist, wobei das Reinigungsgerät eine Geräteschnittstelle aufweist, die mit einer Basisstationsschnittstelle der Basisstation zur kraftübertragenden Verbindung des Motors und der Reinigungswalze über ein Basisstationsgetriebe der Basisstation verbindbar ist. Das Reinigungsgerät und die Basisstation weisen somit korrespondierende Schnittstellen auf, über welche der Motor des Reinigungsgerätes mit dem Basisstationsgetriebe der Basisstation verbindbar ist. Dadurch entstehen die zuvor in Bezug auf das Reinigungsgerät erläuterten Vorteile.Furthermore, a system comprising a cleaning device and a base station is proposed, in particular a cleaning device according to the invention described above and a base station according to the invention described above, wherein the cleaning device rotatable about a rotation axis cleaning roller, a cleaning roller driving motor and between the cleaning roller and the motor arranged gear device, wherein the cleaning roller is rotatable by means of the motor, wherein the cleaning device has a device interface, which is connectable to a base station interface of the base station for force-transmitting connection of the motor and the cleaning roller via a base station transmission of the base station. The cleaning device and the base station thus have corresponding interfaces via which the motor of the cleaning device can be connected to the base station transmission of the base station is. This results in the advantages explained above with respect to the cleaning device.

Darüber hinaus wird vorgeschlagen, dass die Geräteschnittstelle des Reinigungsgerätes ein erstes Geräteschnittstellenelement, insbesondere ein Zahnrad, aufweist, welches mit einem ersten Basisschnittstellenelement, insbesondere einem Zahnrad des Basisstationsgetriebes, verbindbar ist, und dass die Geräteschnittstelle ein zweites Geräteschnittstellenelement, insbesondere ein Zahnrad, aufweist, welches mit einem zweiten Basisschnittstellenelement, insbesondere einem Zahnrad des Basisstationsgetriebes, verbindbar ist. Sowohl die Geräteschnittstelle als auch die Basisstationsschnittstelle weisen somit Elemente zur Verbindung mit der Basisstation bzw. dem Reinigungsgerät auf, so dass der Motor des Reinigungsgerätes im Sinne der Erfindung besonders einfach mit dem Basisstationsgetriebe verbindbar ist bzw. von diesem entkoppelbar ist.In addition, it is proposed that the device interface of the cleaning device has a first device interface element, in particular a gear, which is connectable to a first base interface element, in particular a gear of the base station, and that the device interface, a second device interface element, in particular a gear, which with a second base interface element, in particular a gear of the base station transmission, is connectable. Both the device interface and the base station interface thus have elements for connection to the base station or the cleaning device, so that the motor of the cleaning device within the meaning of the invention is particularly easy to connect to the base station transmission or can be decoupled from this.

Des Weiteren wird vorgeschlagen, dass das Reinigungsgerät zwischen dem Motor und der Reinigungswalze einen Freilauf aufweist, welcher ausgebildet ist, den Motor ohne Beteiligung der Basisstation in einer ersten Drehrichtung mit der Reinigungswalze zu koppeln und in einer zweiten Drehrichtung von der Reinigungswalze zu entkoppeln.Furthermore, it is proposed that the cleaning device between the motor and the cleaning roller has a freewheel, which is designed to couple the motor without involvement of the base station in a first rotational direction with the cleaning roller and to decouple in a second rotational direction of the cleaning roller.

Des Weiteren wird vorgeschlagen, dass das Reinigungsgerät und die Basisstation im Bereich der Geräteschnittstelle und der Basisstationsschnittstelle zueinander formkorrespondierend ausgebildet sind, so dass die Schnittstellen durch eine Anordnung des Reinigungsgerätes an der Basisstation miteinander verbindbar sind. Dadurch erfolgt erfindungsgemäß bereits durch die Anordnung des Reinigungsgerätes an der Basisstation eine Ausrichtung der Schnittstellen zueinander, so dass der Nutzer das Reinigungsgerät wie üblich in die Basisstation hineinstellt, an der Basisstation aufhängt oder ähnliches. Die Basisstation kann beispielsweise auch dazu dienen, einen Akkumulator des Reinigungsgerätes aufzuladen, eine Schmutzkammer des Reinigungsgerätes zu entleeren oder ähnliches. Dabei ist vorteilhaft vorgesehen, dass das Reinigungsgerät durch einen Formschluss stets in der gleichen Stellung an der Basisstation angeordnet ist, so dass automatisch auch die für die Nutzung des Basisstationsgetriebes verwendeten Schnittstellen miteinander verbunden sind. Der Nutzer muss somit nicht separat darauf achten, dass die Geräteschnittstelle und die Basisstationsschnittstelle korrekt zueinander ausgerichtet sind.Furthermore, it is proposed that the cleaning device and the base station in the area of the device interface and the base station interface are designed to correspond in shape to each other, so that the interfaces can be connected to one another by an arrangement of the cleaning device at the base station. As a result, according to the invention, the arrangement of the cleaning device at the base station already aligns the interfaces with one another, so that the user places the cleaning device in the base station as usual, hangs up on the base station or the like. The base station can for example also serve to charge an accumulator of the cleaning device, a dirt chamber of the cleaning device to empty or similar. It is advantageously provided that the cleaning device is always arranged in the same position on the base station by a positive connection, so that automatically also the interfaces used for the use of the base station transmission are interconnected. The user therefore does not have to make sure that the device interface and the base station interface are correctly aligned with each other.

Schließlich wird mit der Erfindung auch ein Verfahren zum Betrieb eines Reinigungsgerätes mit einer um eine Drehachse rotierbaren Reinigungswalze, einem die Reinigungswalze antreibenden Motor und einem zwischen der Reinigungswalze und dem Motor angeordneten Gerätegetriebe vorgeschlagen, wobei die Reinigungswalze während eines Reinigungsvorgangs mittels des Motors rotiert wird, wobei das Reinigungsgerät für einen Regenerationsvorgang zur Regeneration der Reinigungswalze mit einer Basisstation verbunden wird, wobei die Reinigungswalze während der Regeneration über ein mit dem Motor des Reinigungsgerätes verbundenes Basisstationsgetriebe der Basisstation angetrieben wird.Finally, the invention also proposes a method for operating a cleaning device with a cleaning roller rotatable about a rotation axis, a motor driving the cleaning roller and a device gear arranged between the cleaning roller and the motor, wherein the cleaning roller is rotated during a cleaning operation by means of the motor the cleaning device for a regeneration process for the regeneration of the cleaning roller is connected to a base station, wherein the cleaning roller is driven during the regeneration via a base station transmission of the base station connected to the motor of the cleaning device.

Das Reinigungsgerät kann somit zum einen während eines üblichen Reinigungsvorgangs genutzt werden, um Schmutz von einer zu reinigenden Fläche aufzunehmen. Dazu wird die Reinigungswalze mit einer relativ geringen Drehzahl, beispielsweise 300 U/min, rotiert. Während eines Regenerationsvorgangs wird die Reinigungswalze sodann von dem aufgenommenen Schmutz gereinigt. Dazu wird die Reinigungswalze mit einer gegenüber dem üblichen Reinigungsvorgang erhöhten Drehzahl rotiert, so dass der an der Reinigungswalze anhaftende Schmutz vorteilhaft in einen Auffangbehälter geschleudert wird. Die Reinigungswalze steht dann für einen erneuten Reinigungsvorgang und/oder eine Konditionierung mit Reinigungsflüssigkeit zur Verfügung. Da sich die Drehzahlen während des Reinigungsvorgangs und des Regenerationsvorgangs unterscheiden, sind unterschiedliche Getriebe in Kombination mit dem Motor des Reinigungsgerätes erforderlich. Erfindungsgemäß erfolgt die Regeneration der Reinigungswalze mittels des Basisstationsgetriebes der Basisstation, so dass das Reinigungsgerät selbst keine Veränderung in Bezug auf den Motor und/oder das Gerätegetriebe erfordert. Vielmehr wird nach dem erfindungsgemäßen Verfahren die Reinigungswalze mittels des Motors des Reinigungsgerätes und mittels des Basisstationsgetriebes angetrieben. Das Basisstationsgetriebe weist dabei vorteilhaft eine Übersetzung auf, welche bei konstanter Motorleistung des Motors des Reinigungsgerätes zu einer erhöhten Drehzahl, bei gegenüber dem Reinigungsvorgang verringertem Drehmoment führt. Beispielsweise kann die Reinigungswalze während des Reinigungsvorgangs eine Drehzahl von 300 U/min aufweisen und während des Regenerationsvorgangs eine Drehzahl von 6.000 U/min.The cleaning device can thus be used on the one hand during a conventional cleaning process to absorb dirt from a surface to be cleaned. For this purpose, the cleaning roller is rotated at a relatively low speed, for example 300 rpm. During a regeneration process, the cleaning roller is then cleaned of the collected dirt. For this purpose, the cleaning roller is rotated with respect to the usual cleaning process increased speed, so that the adhering to the cleaning roller dirt is advantageously thrown into a receptacle. The cleaning roller is then available for a renewed cleaning process and / or conditioning with cleaning fluid. Since the speeds differ during the cleaning process and the regeneration process, different transmissions are required in combination with the motor of the cleaning device. According to the invention the regeneration of the cleaning roller is effected by means of the base station transmission of the base station, so that the cleaning device itself does not require any change with respect to the engine and / or the gearbox. Rather, the cleaning roller is driven by the motor of the cleaning device and by means of the base station transmission according to the inventive method. The base station transmission in this case advantageously has a ratio which, with a constant engine power of the engine of the cleaning device, leads to an increased rotational speed, with reduced torque compared to the cleaning process. For example, the cleaning roller during the cleaning process have a speed of 300 rev / min and during the regeneration process, a speed of 6,000 rev / min.

Es wird vorgeschlagen, dass die Reinigungswalze mittels eines zwischen dem Motor und der Reinigungswalze angeordneten drehrichtungsabhängigen Freilaufes mit dem Basisstationsgetriebe verbunden und/oder von dem Basisstationsgetriebe getrennt wird, wobei der Motor in Bezug auf eine erste Drehrichtung mit dem Basisstationsgetriebe gekoppelt wird und in Bezug auf eine zweite Drehrichtung von dem Basisstationsgetriebe entkoppelt wird. Der Freilauf schaltet somit in Abhängigkeit von der Drehrichtung des Motors des Reinigungsgerätes den Antriebsstrang für die Reinigungswalze. Bei einer ersten Drehrichtung des Motors ermöglicht der Freilauf ohne Mitwirkung der Basisstation keine kraftübertragende Verbindung zwischen der Reinigungswalze und dem Motor des Reinigungsgerätes bzw. dem Gerätegetriebe. Sofern der Motor in eine dazu entgegengesetzte, zweite Drehrichtung rotiert, stellt der Freilauf eine direkte kraftübertragende Verbindung zwischen dem Motor bzw. dem Getriebe des Reinigungsgerätes und der Reinigungswalze her, so dass ausschließlich der Antriebstrang des Reinigungsgerätes, ohne Beteiligung der Basisstation, zur Rotation der Reinigungswalze beiträgt.It is proposed that the cleaning roller is connected to the base station transmission and / or separated from the base station transmission by means of a direction-dependent freewheel disposed between the motor and the cleaning roller, the motor being coupled to the base station transmission with respect to a first rotational direction and with respect to a second direction of rotation is decoupled from the base station transmission. The freewheel thus switches the drive train for the cleaning roller depending on the direction of rotation of the motor of the cleaning device. In a first direction of rotation of the motor, the freewheel without the cooperation of the base station allows no force-transmitting connection between the cleaning roller and the motor of the cleaning device or the gear unit. If the motor rotates in an opposite, second rotational direction, the freewheel establishes a direct force-transmitting connection between the motor or the transmission of the cleaning device and the cleaning roller, so that only the drive train of the cleaning device, without involvement of the base station, for rotation of the cleaning roller contributes.

Beschreibung der AusführungsformenDescription of the embodiments

Figur 1 zeigt ein Reinigungsgerät 1 sowie eine Basisstation 8 in einem nicht miteinander verbundenen Zustand. FIG. 1 shows a cleaning device 1 and a base station 8 in an unconnected state.

Das Reinigungsgerät 1 ist hier beispielhaft als Feuchtwischgerät ausgebildet. Dieses beinhaltet eine um eine Drehachse 2 rotierbare Reinigungswalze 3, welche einen Reinigungsbelag 16 aufweist. Der Reinigungsbelag 16 kann beispielsweise Mikrofasern aufweisen oder als Schwamm ausgebildet sein. Der Reinigungsbelag 16 ist geeignet, Schmutz von einer zu reinigenden Fläche zu lösen, aufzunehmen und/oder Schmutzwasser aufgrund des Kapillareffekts zu speichern.The cleaning device 1 is here exemplified as a wet wiper. This includes a rotatable around a rotation axis 2 cleaning roller 3, which has a cleaning pad 16. The cleaning pad 16 may for example comprise microfibers or be formed as a sponge. The cleaning pad 16 is adapted to solve dirt from a surface to be cleaned, to absorb and / or to store dirty water due to the capillary effect.

Das Reinigungsgerät 1 weist des Weiteren einen Motor 4 zum Antrieb der Reinigungswalze 3 auf. Der Motor 4 ist über ein Gerätegetriebe 5 und einen drehrichtungsgebundenen Freilauf 11 mit der Reinigungswalze 3 verbunden.The cleaning device 1 further comprises a motor 4 for driving the cleaning roller 3. The motor 4 is connected via a gearbox 5 and a directional freewheel 11 with the cleaning roller 3.

Das Reinigungsgerät 1 weist darüber hinaus eine Geräteschnittstelle 6 zur Verbindung des Reinigungsgerätes 1 mit der Basisstation 8 auf. Die Geräteschnittstelle 6 verfügt dazu über ein erstes Geräteschnittstellenelement 9 und ein zweites Geräteschnittstellenelement 10.The cleaning device 1 also has a device interface 6 for connecting the cleaning device 1 to the base station 8. For this purpose, the device interface 6 has a first device interface element 9 and a second device interface element 10.

Die Basisstation 8 weist ein Basisstationsgetriebe 7 auf, sowie eine Basisstationsschnittstelle 13 mit einem ersten Basisschnittstellenelement 14 und einem zweiten Basisschnittstellenelement 15. Die Basisstationsschnittstelle 13 und das Basisstationsgetriebe 7 stellen eine Parallelverbindung 12 bereit, welche im miteinander verbundenen Zustand des Reinigungsgerätes 1 und der Basisstation 8 geeignet ist, den Freilauf 11 des Reinigungsgerätes 1 zu überbrücken.The base station 8 has a base station transmission 7, and a base station interface 13 with a first base interface element 14 and a second base interface element 15. The base station interface 13 and the base station transmission 7 provide a parallel connection 12 which is suitable in the connected state of the cleaning device 1 and the base station 8 is to bridge the freewheel 11 of the cleaning device 1.

Figur 2 zeigt eine Schaltskizze des Reinigungsgerätes 1 und der Basisstation 8 gemäß Figur 1. Dabei ist der Antriebstrang des Reinigungsgerätes 1 vollständig von der Basisstation 8 entkoppelt. Dieser Zustand entspricht einem üblichen Reinigungsvorgang des Reinigungsgerätes 1, bei welchem die Reinigungswalze 3 genutzt wird, um eine zu reinigende Fläche von Schmutz zu befreien. FIG. 2 shows a circuit diagram of the cleaning device 1 and the base station 8 according to FIG. 1 , The drive train of the cleaning device 1 is completely decoupled from the base station 8. This state corresponds to a conventional cleaning operation of the cleaning device 1, in which the cleaning roller 3 is used to rid a surface to be cleaned of dirt.

Während des Reinigungsvorgangs wird die Reinigungswalze 3 des Reinigungsgerätes 1 über die zu reinigende Fläche geführt. Dabei treibt der Motor 4 die Reinigungswalze 3 an, so dass diese um die Drehachse 2 rotiert. Der Motor 4 weist beispielsweise eine Drehzahl von 6.000 U/min auf, wobei dessen Abtriebswelle in eine erste Richtung rotiert. Die Abtriebsseite des Motors 4 ist mit dem Gerätegetriebe 5 verbunden, welches hier beispielsweise ein Übersetzungsverhältnis von 20:1 aufweist, so dass die Abtriebsdrehzahl des Gerätegetriebes 5 300 U/min beträgt. Die Abtriebsseite des Gerätegetriebes 5 ist über den Freilauf 11 mit der Reinigungswalze 3 verbunden, wobei der Freilauf 11 die Rotationsbewegung des Motors 4 auf die Reinigungswalze 3 überträgt. Der Freilauf 11 ist eine nur in eine Drehrichtung wirkende Kupplung, welche das Drehmoment des Motors 4 bei der gezeigten ersten Drehrichtung auf die Reinigungswalze 3 überträgt.During the cleaning process, the cleaning roller 3 of the cleaning device 1 is guided over the surface to be cleaned. In this case, the motor 4 drives the cleaning roller 3, so that it rotates about the rotation axis 2. For example, the engine 4 has a speed of 6,000 rpm, with its output shaft rotating in a first direction. The output side of the motor 4 is connected to the gear unit 5, which here, for example, a transmission ratio of 20: 1, so that the output speed of the gearbox transmission is 5 300 U / min. The output side of the gearbox 5 is connected via the freewheel 11 with the cleaning roller 3, wherein the freewheel 11, the rotational movement of the motor 4 transmits to the cleaning roller 3. The freewheel 11 is acting only in one direction of rotation clutch, which is the torque of the motor 4 in the first rotational direction shown transfers to the cleaning roller 3.

Der Motor 4 ist für einen üblichen Reinigungsvorgang ausgelegt, welcher ein hohes Drehmoment bei niedrigen Drehzahlen erfordert. Die Motorleistung kann beispielsweise 50 Watt betragen.The engine 4 is designed for a conventional cleaning operation which requires high torque at low speeds. The engine power can be for example 50 watts.

Die Basisstation 8 ist während des gezeigten Reinigungsvorgangs noch nicht beteiligt, d. h. dass die Geräteschnittstelle 6 noch nicht mit der Basisstationsschnittstelle 13 verbunden ist.The base station 8 is not yet involved during the cleaning process shown, d. H. the device interface 6 is not yet connected to the base station interface 13.

Figur 3 zeigt das Reinigungsgerät 1 und die Basisstation 8 in einem miteinander verbundenen Zustand. Dabei ist das Reinigungsgerät 1 in einen Teilbereich der Basisstation 8 eingesetzt. Die Geräteschnittstelle 6 ist mit der Basisstationsschnittstelle 13 verbunden, wobei das erste Geräteschnittstellenelement 9 des Reinigungsgerätes 1 mit dem ersten Basisschnittstellenelement 14 der Basisstation 8 verbunden ist und das zweite Basisschnittstellenelement 15 der Basisstation 8 mit dem zweiten Geräteschnittstellenelement 10 des Reinigungsgerätes 1. Die Geräteschnittstellenelemente 9,10 des Reinigungsgerätes 1 und die Basisschnittstellenelemente 14, 15 der Basisstation 8 sind jeweils als Zahnräder ausgebildet, welche für eine Kraftübertragung ineinandergreifen. FIG. 3 shows the cleaning device 1 and the base station 8 in an interconnected state. In this case, the cleaning device 1 is inserted into a partial area of the base station 8. The device interface 6 is connected to the base station interface 13, wherein the first device interface element 9 of the cleaning device 1 is connected to the first base interface element 14 of the base station 8 and the second base interface element 15 of the base station 8 to the second device interface element 10 of the cleaning device 1. The device interface elements 9,10 of the cleaning device 1 and the base interface elements 14, 15 of the base station 8 are each formed as gears, which mesh for a power transmission.

Die Positionierung des Reinigungsgerätes 1 an der Basisstation 8 erfolgt mittels eines Formschlusses der beiderseitigen Gehäuse. Durch den Formschluss werden gleichzeitig auch die Geräteschnittstelle 6 und die Basisstationsschnittstelle 13 in eine zueinander korrespondierende Position gebracht, in welcher sich die Geräteschnittstellenelemente 9, 10 des Reinigungsgerätes 1 und die Basisschnittstellenelemente 14,15 der Basisstation 8 automatisch miteinander verbinden. Über die Geräteschnittstelle 6 und die Basisstationsschnittstelle 13 erfolgt eine kraftübertragende Kopplung des Motors 4 des Reinigungsgerätes 1 über die Parallelverbindung 12 der Basisstation 8 mit der Reinigungswalze 3. Somit treibt der Motor 4 die Reinigungswalze 3 über das Basisstationsgetriebe 7 der Basisstation 8 an. Hierdurch ist ein Regenerationsvorgang der Reinigungswalze 3 mit großer Drehzahl möglich.The positioning of the cleaning device 1 to the base station 8 by means of a positive connection of the mutual housing. As a result of the positive connection, the device interface 6 and the base station interface 13 are simultaneously brought into a mutually corresponding position, in which the device interface elements 9, 10 of the cleaning device 1 and the base interface elements 14, 15 of the base station 8 automatically connect to one another. Via the device interface 6 and the base station interface 13 there is a force-transmitting coupling of the motor 4 of the cleaning device 1 via the parallel connection 12 of the base station 8 with the cleaning roller 3. Thus, the motor 4 drives the cleaning roller 3 over the base station transmission 7 of the base station 8 at. As a result, a regeneration process of the cleaning roller 3 is possible at high speed.

Figur 4 zeigt im Detail die Schaltskizze in Bezug auf den verbundenen Zustand von Reinigungsgerät 1 und Basisstation 8 gemäß Figur 3. Dabei sind das Reinigungsgerät 1 und die Basisstation 8 via der Geräteschnittstelle 6 und der Basisstationsschnittstelle 13 miteinander verbunden. Während des Regenerationsvorgangs rotiert der Motor 4 in eine zweite Richtung, welche der Rotationsrichtung während des Reinigungsvorgangs entgegengesetzt ist. Im Beispiel rotiert die Abtriebswelle des Motors 4 mit einer Drehzahl von 6.000 U/min. Durch das Übersetzungsverhältnis 20:1 des Gerätegetriebes 4 wird diese Drehzahl von 6.000 U/min auf eine Abtriebsdrehzahl von 300 U/min herabgesetzt. Da der Motor 4 bzw. die Abtriebswelle des Gerätegetriebes 5 während der Regeneration jedoch in die zweite Richtung rotiert, kommt es nicht zu einer Kraftübertragung zwischen dem Gerätegetriebe 5 und dem Freilauf 11. Vielmehr ist der Freilauf in dieser zweiten Drehrichtung nicht wirksam, so dass das Drehmoment des Gerätegetriebes 5 ausschließlich über die Geräteschnittstelle 6 und die Basisstationsschnittstelle 13 auf das Basisstationsgetriebe 7 der Basisstation 8 übertragen wird. Dazu ist das erste Geräteschnittstellenelement 9, hier ein erstes Zahnrad, mit dem ersten Basisschnittstellenelement 14 der Basisstation 8, hier ebenfalls einem Zahnrad, verbunden. Es kommt somit zu einer Übertragung des Drehmoments auf das Basisstationsgetriebe 7, welches hier ein Übersetzungsverhältnis von 1:20 aufweist. Dadurch wird die Drehzahl von 300 U/min auf eine Drehzahl von 6.000 U/min übersetzt. Zugleich erfolgt eine Drehrichtungsumkehr. Die Abtriebswelle des Basisstationsgetriebes 7 weist das zweite Basisschnittstellenelement 15 auf, welches mit dem zweiten Geräteschnittstellenelement 10 verbunden ist. Somit wird die Reinigungswalze 3 über die Parallelverbindung 12 der Basisstation 8 in Rotation versetzt. Im Gegensatz zu dem Reinigungsvorgang rotiert die Reinigungswalze 3 nun mit einer Drehzahl von 6.000 U/min (d.h. hier der Drehzahl des Motors 4), wodurch in dem Reinigungsbelag 16 der Reinigungswalze 3 gespeicherter Schmutz und/ oder gespeichertes Schmutzwasser optimal weggeschleudert werden kann, vorteilhaft in einen Auffangbehälter der Basisstation 8. FIG. 4 shows in detail the circuit diagram with respect to the connected state of cleaning device 1 and base station 8 according to FIG. 3 , The cleaning device 1 and the base station 8 are connected to each other via the device interface 6 and the base station interface 13. During the regeneration process, the motor 4 rotates in a second direction, which is opposite to the direction of rotation during the cleaning process. In the example, the output shaft of the motor 4 rotates at a speed of 6,000 rpm. Due to the transmission ratio 20: 1 of the gearbox 4, this speed is reduced from 6,000 rpm to an output speed of 300 rev / min. However, since the engine 4 or the output shaft of the gearbox 5 rotates during the regeneration in the second direction, there is no power transmission between the gearbox 5 and the freewheel 11. Rather, the freewheel in this second direction of rotation is not effective, so that the Torque of the gearbox 5 is transmitted exclusively via the device interface 6 and the base station interface 13 to the base station transmission 7 of the base station 8. For this purpose, the first device interface element 9, here a first gearwheel, is connected to the first base interface element 14 of the base station 8, here likewise a gearwheel. Thus, there is a transfer of torque to the base station transmission 7, which here has a transmission ratio of 1:20. This translates the speed from 300 rpm to a speed of 6,000 rpm. At the same time there is a reversal of direction. The output shaft of the base station transmission 7 has the second base interface element 15, which is connected to the second device interface element 10. Thus, the cleaning roller 3 is set in rotation via the parallel connection 12 of the base station 8. In contrast to the cleaning process, the cleaning roller 3 now rotates at a speed of 6,000 rev / min (ie here the speed of the motor 4), which in the cleaning pad 16 of the cleaning roller 3 stored dirt and / or stored dirty water can be optimally thrown away, advantageously in a collecting container of the base station. 8

Für den gezeigten Regenerationsvorgang sind geringere Drehmomente notwendig als für den Reinigungsvorgang. Daher kann die höhere Drehzahl für den Regenerationsvorgang mittels des Basisstationsgetriebes 7 bei gleicher Motorleistung des Motors 4 erreicht werden. Das Basisstationsgetriebe 7 ist in der Basisstation 8 angeordnet, so dass der Bauraum des Reinigungsgerätes 1 möglichst gering bleibt. Darüber hinaus sind keine Änderungen an dem Motor 4 und dem Gerätegetriebe 5 des Reinigungsgerätes 1 notwendig, um das Abschleudern des Schmutzes/Schmutzwassers von der Reinigungswalze 3 zu erreichen.Lower torques are required for the regeneration process shown than for the cleaning process. Therefore, the higher speed for the regeneration process by means of the base station transmission 7 can be achieved with the same engine power of the engine 4. The base station transmission 7 is arranged in the base station 8, so that the installation space of the cleaning device 1 remains as low as possible. In addition, no changes to the motor 4 and the gearbox 5 of the cleaning device 1 are necessary to achieve the centrifuging of the dirt / dirty water from the cleaning roller 3.

Die Schaltung zwischen dem Antriebsstrang des Reinigungsgerätes 1 für den Reinigungsvorgang und der Parallelverbindung 12 der Basisstation 8 für den Regenerationsvorgang erfolgt mittels der Drehrichtung des Motors 4 sowie dem Freilauf 11 des Reinigungsgerätes 1, welcher so ausgelegt ist, dass bei einer ersten Drehrichtung des Motors eine direkte Kraftübertragung, d. h. ohne Nutzung der Parallelverbindung 12 der Basisstation 8, auf die Reinigungswalze 3, stattfindet, während bei einer zweiten, dazu entgegengesetzten Drehrichtung keine Kraftübertragung über den Freilauf 11 stattfindet. Vielmehr wird das Drehmoment über die Geräteschnittstelle 6 und die Basisstationsschnittstelle 13 auf die Parallelverbindung 12 der Basisstation 8 übertragen, woraufhin eine Erhöhung der Drehzahl mittels des Basisstationsgetriebes 7 stattfindet, so dass die Reinigungswalze 3 des Reinigungsgerätes 1 während des Regenerationsvorgangs mit zu dem Reinigungsvorgang erhöhter Drehzahl rotieren kann.The circuit between the drive train of the cleaning device 1 for the cleaning process and the parallel connection 12 of the base station 8 for the regeneration process by means of the direction of rotation of the motor 4 and the freewheel 11 of the cleaning device 1, which is designed so that at a first rotational direction of the motor direct Power transmission, ie without the use of the parallel connection 12 of the base station 8, on the cleaning roller 3, takes place while at a second, opposite rotational direction no power transmission via the freewheel 11 takes place. Rather, the torque is transmitted via the device interface 6 and the base station interface 13 to the parallel connection 12 of the base station 8, whereupon an increase in the speed takes place by means of the base station 7, so that the cleaning roller 3 of the cleaning device 1 rotate during the regeneration process with increased speed to the cleaning process can.
