  • the wiping body thus moistened is guided over a surface to be cleaned during a wiping operation, the wiping body taking up dirt from the surface to be cleaned.
  • the wiping body is increasingly covered with dirt, so that regeneration of the wiping body is necessary.
  • the wiper body is lifted off the surface to be cleaned, surrounded with a housing and sprayed with unused cleaning fluid.
  • the wiper body rotates so that cleaning fluid and / or dirt are expelled from the wiper body, meet the inside of the housing and are transferred to a receiving tank.
  • the disadvantage here is that a large amount of cleaning fluid is required for cleaning the wiper body during regeneration operation in order to be able to throw off dirt accumulated on the wiper body by the centrifugal forces acting on the dirt or the cleaning fluid during rotation of the wiper body.

  • the regeneration of the cleaning coating of the cleaning roller is no longer carried out exclusively by spinning off liquid and / or dirt from the fibers of the cleaning coating pointing radially outward due to the rotation of the cleaning roller.
  • the cleaning roller in particular the fibers of the cleaning pad, is now assigned a braking element and a guide element, the braking element being designed to brake the fibers of the cleaning pad rotating about the roller axis, so that these are abruptly braked by the braking element and with their free ends bend the impact edge of the braking element away, and wherein the guide element is designed and arranged in such a way that the liquid or the thrown-off dirt thrown off by the bent fibers is guided to a liquid channel.
  • the central component of the invention is the braking element with the following guide element for removing the liquid or dirt removed from the fibers by means of the braking element.
  • the braking element is lowered into the cleaning surface of the rotating cleaning roller.
  • the fibers of the cleaning pad stand up in front of the braking element due to the action of the centrifugal force (by stretching the fibers) and move around the roller axis at the angular speed of the cleaning roller.
  • the fibers on the braking element are stopped abruptly, the free ends of the fibers moving at an increased angular velocity around the new center of rotation on the braking element.
  • the free ends of the fibers bend around the impact edge in the direction of the guide element, the forces acting on the fibers due to the stopping on the braking element being many times higher than the centrifugal force due solely to the rotation of the cleaning roller around the roller axis (without Braking element).
  • Dirt contained in the cleaning covering is loosened and thrown out by the impact, namely in the direction of the guide element, which then supplies the liquid and the dirt to a liquid channel which, for example, opens into a dirty water tank.
  • the fibers of the cleaning covering are drawn under the braking element. By pulling back, the fibers are additionally stripped off and pressed out on the braking element. Finally, the fibers can line up behind the braking element and, if necessary, throw off any adhering liquid or adhering dirt.
  • the liquid or dirt detached by the bending of the free ends of the fibers has a kinetic energy which leads to a throwing off onto the guide element.
  • the guide element guides the liquid and the dirt to the liquid channel and, on the other hand, prevents them from dripping onto the cleaning surface again.
  • the braking element is arranged relative to the cleaning pad of the cleaning roller in such a way that on the one hand there is a free distance between the braking element and the roots of the fibers, and on the other hand there is a free distance between the impact edge and the outermost end region of the free ends of the fibers. It is thereby achieved that the free ends of the fibers have a freedom of movement in order to bend over the impact edge in the event of an impact on the impact edge of the braking element, and that the fibers are pulled away from the impact edge in the opposite direction as the rotation of the cleaning roller progresses and between the cleaning roller and can be passed through the braking element.
  • the braking element be immovably arranged on the wet cleaning device during the regeneration operation.
  • the braking element is thus stationary relative to the wet cleaning device, while the fibers of the cleaning pad are moved against the braking element by the rotation of the cleaning roller.
  • the braking element is moved during the regeneration operation in a direction which is opposite to the direction of rotation of the cleaning roller. As a result, the speed at which the fibers of the cleaning pad strike the braking element can be increased further.
  • the braking element and the guide element are designed as a common element.
  • the braking element and the guide element are formed together as an arcuate element which is convexly curved on a side facing away from the cleaning roller and is concavely curved on a side pointing towards the cleaning roller.
  • the arcuate configuration of the common element is particularly suitable for allowing the bent free ends of the fibers to impact the guide element on the convex curved side facing away from the cleaning roller and thus to achieve an additional cleaning effect by the free ends hitting the guide element .
  • the convex curvature also ensures that the liquid or the dirt can be guided to the liquid channel along the negative slope of the surface, following the force of gravity.
  • the opposite, concavely curved side of the common element, which points towards the cleaning roller, is preferably concavely curved so that the free ends of the fibers can straighten up again as early as possible under the common element when the cleaning roller continues to rotate.
  • the impact edge of the braking element is convexly curved.
  • the fibers of the cleaning pad are guided as gently as possible around the braking element or the impact edge, so that the service life of the cleaning pad is increased and, on the other hand, it facilitates deflecting the free ends of the fibers in the direction of the guide element.
  • the impact edge of the braking element preferably has a height of approximately one third of a fiber length of the fibers. As a result, a sufficient distance can be achieved in the radial direction (based on the roller axis) both below and above the impact edge, which distance is suitable for retracting the fibers under the braking element or for deflecting the free ends of the fibers over the braking element.
  • the impact edge be at a distance from the fiber roots of the fibers of a quarter to a half of a fiber length of the fibers in the radial direction with respect to the roller axis. This distance is sufficient to pull the fibers between the braking element and the fiber roots of the fibers without causing damage to the cleaning pad. On the other hand, this distance is so small that an additional wiping effect of the fibers between the cleaning roller and the braking element can be achieved.
  • the guide element extends in the direction of rotation of the cleaning roller, starting from the braking element to the liquid channel, in particular forming an extension of a channel wall of the liquid channel.
  • This configuration enables loss-free transportation of the liquid or dirt from the braking element into the liquid channel.

  • the braking element or the guide element is usually only required during the regeneration operation of the cleaning roller. It is therefore advisable to remove the braking element from the cleaning surface of the cleaning roller before carrying out a wiping operation, ie to move it away from the cleaning roller. Accordingly, the guide element should also be moved away from the cleaning roller. If the braking element and the guide element are designed as a common element, the displacement accordingly takes place simultaneously.

  • the braking element and / or the guide element now provides a guide surface on which liquid flows from a nozzle to the cleaning roller can flow.
  • the guide surface of the braking element or of the guide element faces the cleaning roller and thus also the cleaning covering.
  • the liquid emerging from the nozzle is no longer applied directly to the cleaning roller, but rather first to the braking element and / or the guide element and from there to the cleaning roller.
  • the term liquid is also understood to mean a vapor, liquid drop, spray mist or the like.

  • the liquid generates a liquid spot on the braking element or the guide element, from which portions of the liquid move essentially radially in all directions, for example also against gravity. As the distance to the nozzle increases, the liquid orientates itself more and more vertically following the direction of gravity, as a result of which the liquid is fanned out.

Der Wischkörper rotiert, so dass Reinigungsflüssigkeit und/oder Schmutz aus dem Wischkörper ausgetrieben werden, auf die Innenseite des Gehäuses treffen und in einen Aufnahmetank überführt werden. Nachteilig ist dabei, dass während des Regenerationsbetriebs eine große Menge Reinigungsflüssigkeit zur Reinigung des Wischkörpers erforderlich ist, um auf dem Wischkörper angelagerten Schmutz durch die bei der Rotation des Wischkörpers an dem Schmutz bzw. der Reinigungsflüssigkeit angreifenden Zentrifugalkräfte abschleudern zu können.During the wiping operation, the wiping body is increasingly covered with dirt, so that regeneration of the wiping body is necessary. For this purpose, the wiper body is lifted off the surface to be cleaned, surrounded with a housing and sprayed with unused cleaning fluid. The wiper body rotates so that cleaning fluid and / or dirt are expelled from the wiper body, meet the inside of the housing and are transferred to a receiving tank. The disadvantage here is that a large amount of cleaning fluid is required for cleaning the wiper body during regeneration operation in order to be able to throw off dirt accumulated on the wiper body by the centrifugal forces acting on the dirt or the cleaning fluid during rotation of the wiper body.

Zusammenfassung der ErfindungSummary of the invention

Ausgehend von dem vorgenannten Stand der Technik ist es Aufgabe der Erfindung, ein Feuchtreinigungsgerät der vorgenannten Art zu schaffen, bei welchem eine Regeneration der Reinigungswalze mit bestmöglichem Ergebnis und insbesondere mit einem möglichst geringen Einsatz von Flüssigkeit und kurzer Regenerationszeit möglich ist.Starting from the aforementioned prior art, it is an object of the invention to provide a wet cleaning device of the aforementioned type in which regeneration of the cleaning roller is possible with the best possible result and in particular with the least possible use of liquid and a short regeneration time.

Zur Lösung der vorgenannten Aufgabe wird zunächst ein Feuchtreinigungsgerät vorgeschlagen, welches ein Abbremselement und ein Führungselement zum Unterstützen des Entfernens und Ableitens von Flüssigkeit und/oder Schmutz von der Reinigungswalze zu einem Flüssigkeitskanal aufweist, wobei das Abbremselement eine den Fasern des rotierenden Reinigungsbelages entgegenstehende Aufprallkante aufweist, wobei das Führungselement in Rotationseinrichtung der Reinigungswalze hinter der Aufprallkante angeordnet ist, und wobei die Aufprallkante während eines Regenerationsbetriebs des Feuchtreinigungsgerätes soweit zwischen den Fasern des Reinigungsbelags angeordnet ist, dass freie Ende der Fasern in radialer Richtung nach außen über die Aufprallkante hinwegragen und bei einem Aufprall auf die Aufprallkante in Richtung des Führungselementes umgelenkt werden.To solve the aforementioned task, a wet cleaning device is first proposed, which has a braking element and a guide element for supporting the removal and discharge of liquid and / or dirt from the cleaning roller to a liquid channel, the braking element having an impact edge opposite the fibers of the rotating cleaning pad, the guide element in the rotating device of the cleaning roller behind the Impact edge is arranged, and wherein the impact edge during a regeneration operation of the wet cleaning device so far between the fibers of the cleaning surface is arranged that the free ends of the fibers protrude radially outward beyond the impact edge and are deflected in the event of an impact on the impact edge in the direction of the guide element.

Erfindungsgemäß erfolgt die Regeneration des Reinigungsbelages der Reinigungswalze nun nicht mehr ausschließlich durch Abschleudern von Flüssigkeit und/oder Schmutz von den durch die Rotation der Reinigungswalze radial nach außen weisenden Fasern des Reinigungsbelages. Vielmehr sind der Reinigungswalze, insbesondere den Fasern des Reinigungsbelages, nun ein Abbremselement und ein Führungselement zugeordnet, wobei das Abbremselement ausgebildet ist, die Fasern des um die Walzenachse rotierenden Reinigungsbelages abzubremsen, so dass diese abrupt von dem Abbremselement gebremst werden und mit ihren freien Enden über die Aufprallkante des Abbremselements hinweg abknicken, und wobei das Führungselement so ausgebildet und angeordnet ist, dass die von den umgeknickten Fasern abgeschleuderte Flüssigkeit bzw. der abgeschleuderte Schmutz zu einem Flüssigkeitskanal geleitet wird. Durch die Massenträgheit der abrupt abgebremsten Fasern und den neuen Rotationsmittelpunkt der Fasern an dem Abbremselement, entsteht ein Peitscheneffekt, bei welchem zwischen den Fasern des Reinigungsbelages anhaftende Flüssigkeit und/oder anhaftender Schmutz herausgerissen werden und über das Führungselement zu dem Flüssigkeitskanal gelangen. Die über die Aufprallkante des Abbremselements umgeknickten freien Enden der Fasen können Beschleunigungen erreichen, welche mehr als siebenmal so groß sind wie die alleine aufgrund der Zentrifugalkraft um die Walzenachse erreichte Beschleunigung.According to the invention, the regeneration of the cleaning coating of the cleaning roller is no longer carried out exclusively by spinning off liquid and / or dirt from the fibers of the cleaning coating pointing radially outward due to the rotation of the cleaning roller. Rather, the cleaning roller, in particular the fibers of the cleaning pad, is now assigned a braking element and a guide element, the braking element being designed to brake the fibers of the cleaning pad rotating about the roller axis, so that these are abruptly braked by the braking element and with their free ends bend the impact edge of the braking element away, and wherein the guide element is designed and arranged in such a way that the liquid or the thrown-off dirt thrown off by the bent fibers is guided to a liquid channel. Due to the inertia of the abruptly decelerated fibers and the new center of rotation of the fibers on the decelerating element, a whip effect arises in which adhering liquid and / or adhering dirt are torn out between the fibers of the cleaning covering and reach the liquid channel via the guide element. The free ends of the bevels which are bent over the impact edge of the braking element can reach accelerations which are more than seven times as great as the acceleration achieved solely due to the centrifugal force around the roller axis.

Zentraler Bestandteil der Erfindung ist das Abbremselement mit dem nachfolgenden Führungselement zum Abführen der mittels des Abbremselementes von den Fasern entfernten Flüssigkeit bzw. des Schmutzes. Zum Lösen der Flüssigkeit bzw. des Schmutzes wird das Abbremselement in den Reinigungsbelag der rotierenden Reinigungswalze abgesenkt. Die Fasern des Reinigungsbelages stellen sich durch die Wirkung der Zentrifugalkraft vor dem Abbremselement auf (durch ein Strecken der Fasern) und bewegen sich mit der Winkelgeschwindigkeit der Reinigungswalze um die Walzenachse. An dem Abbremselement werden die Fasern schlagartig gestoppt, wobei sich die freien Enden der Fasern mit erhöhter Winkelgeschwindigkeit um den neuen Rotationsmittelpunkt an dem Abbremselement bewegen. Die freien Enden der Fasern knicken um die Aufprallkante in Richtung des Führungselementes ab, wobei die Kräfte, die durch das Stoppen an dem Abbremselement auf die Fasern wirken, um ein Vielfaches höher sind als die Zentrifugalkraft durch ausschließlich die Rotation der Reinigungswalze um die Walzenachse (ohne Abbremselement). In dem Reinigungsbelag enthaltener Schmutz wird durch den Aufprall gelöst und herausgeschleudert, nämlich in Richtung des Führungselementes, welches die Flüssigkeit und den Schmutz anschließend einem Flüssigkeitskanal zuführt, welcher bspw. in einen Schmutzwassertank mündet. Bei fortgeführter Rotation der Reinigungswalze werden die Fasern des Reinigungsbelages unter dem Abbremselement hindurchgezogen. Durch das Zurückziehen werden die Fasern zusätzlich an dem Abbremselement abgestreift und ausgepresst. Schließlich können sich die Fasern hinter dem Abbremselement wieder aufstellen und ggf. noch anhaftende Flüssigkeit bzw. anhaftenden Schmutz abschleudern.The central component of the invention is the braking element with the following guide element for removing the liquid or dirt removed from the fibers by means of the braking element. To solve the liquid or dirt, the braking element is lowered into the cleaning surface of the rotating cleaning roller. The fibers of the cleaning pad stand up in front of the braking element due to the action of the centrifugal force (by stretching the fibers) and move around the roller axis at the angular speed of the cleaning roller. The fibers on the braking element are stopped abruptly, the free ends of the fibers moving at an increased angular velocity around the new center of rotation on the braking element. The free ends of the fibers bend around the impact edge in the direction of the guide element, the forces acting on the fibers due to the stopping on the braking element being many times higher than the centrifugal force due solely to the rotation of the cleaning roller around the roller axis (without Braking element). Dirt contained in the cleaning covering is loosened and thrown out by the impact, namely in the direction of the guide element, which then supplies the liquid and the dirt to a liquid channel which, for example, opens into a dirty water tank. As the cleaning roller continues to rotate, the fibers of the cleaning covering are drawn under the braking element. By pulling back, the fibers are additionally stripped off and pressed out on the braking element. Finally, the fibers can line up behind the braking element and, if necessary, throw off any adhering liquid or adhering dirt.

Die durch das Umknicken der freien Enden der Fasern abgelöste Flüssigkeit bzw. Schmutz haben durch die Rotation der Reinigungswalze eine Bewegungsenergie, die zu einem Abschleudern auf das Führungselement führt. Das Führungselement leitet die Flüssigkeit und den Schmutz zu dem Flüssigkeitskanal und verhindert andererseits, dass diese wieder auf den Reinigungsbelag abtropfen können.Due to the rotation of the cleaning roller, the liquid or dirt detached by the bending of the free ends of the fibers has a kinetic energy which leads to a throwing off onto the guide element. The guide element guides the liquid and the dirt to the liquid channel and, on the other hand, prevents them from dripping onto the cleaning surface again.

Das Abbremselement ist relativ zu dem Reinigungsbelag der Reinigungswalze derart angeordnet, dass einerseits ein freier Abstand zwischen dem Abbremselement und den Wurzeln der Fasern besteht, sowie zum anderen ein freier Abstand zwischen der Aufprallkante und dem äußersten Endbereich der freien Enden der Fasern. Dadurch wird erreicht, dass die freien Enden der Fasern einen Bewegungsspielraum haben, um bei dem Aufprall auf die Aufprallkante des Abbremselementes über die Aufprallkante umzuknicken, und dass die Fasern bei fortschreitender Rotation der Reinigungswalze in dem Umknicken entgegengesetzter Richtung von der Aufprallkante weggezogen und zwischen der Reinigungswalze und dem Abbremselement hindurchgeführt werden können.The braking element is arranged relative to the cleaning pad of the cleaning roller in such a way that on the one hand there is a free distance between the braking element and the roots of the fibers, and on the other hand there is a free distance between the impact edge and the outermost end region of the free ends of the fibers. It is thereby achieved that the free ends of the fibers have a freedom of movement in order to bend over the impact edge in the event of an impact on the impact edge of the braking element, and that the fibers are pulled away from the impact edge in the opposite direction as the rotation of the cleaning roller progresses and between the cleaning roller and can be passed through the braking element.

Es wird vorgeschlagen, dass das Abbremselement während des Regenerationsbetriebs unbeweglich an dem Feuchtreinigungsgerät angeordnet ist. Somit steht das Abbremselement relativ zu dem Feuchtreinigungsgerät ortsfest, während die Fasern des Reinigungsbelages durch die Rotation der Reinigungswalze gegen das Abbremselement bewegt werden. Alternativ kann es jedoch auch vorgesehen sein, dass das Abbremselement während des Regenerationsbetriebs in eine Richtung bewegt wird, welche der Rotationsrichtung der Reinigungswalze entgegengesetzt ist. Dadurch kann die Geschwindigkeit, mit welcher die Fasern des Reinigungsbelages auf das Abbremselement prallen, zusätzlich erhöht werden.It is proposed that the braking element be immovably arranged on the wet cleaning device during the regeneration operation. The braking element is thus stationary relative to the wet cleaning device, while the fibers of the cleaning pad are moved against the braking element by the rotation of the cleaning roller. Alternatively, however, it can also be provided that the braking element is moved during the regeneration operation in a direction which is opposite to the direction of rotation of the cleaning roller. As a result, the speed at which the fibers of the cleaning pad strike the braking element can be increased further.

Des Weiteren wird vorgeschlagen, dass das Abbremselement und das Führungselement als ein gemeinsames Element ausgebildet sind. Insbesondere wird vorgeschlagen, dass das Abbremselement und das Führungselement gemeinsam als bogenförmiges Element ausgebildet sind, welches auf einer von der Reinigungswalze weg weisenden Seite konvex gekrümmt ist und auf einer zu der Reinigungswalze hin weisenden Seite konkav gekrümmt ist. Durch die einteilige Ausbildung des Abbremselementes mit dem Führungselement wird ein fluiddichter Verbund zwischen dem Abbremselement und dem Führungselement geschaffen, sodass an dem Abbremselement von den Fasern des Reinigungsbelags abgeschleuderte Flüssigkeit nicht zwischen dem Abbremselement und dem Führungselement durchströmen, insbesondere auf die Reinigungswalze abtropfen, kann. Darüber hinaus bietet die einteilige Ausgestaltung auch Vorteile bei der Montage des Abbremselementes bzw. des Führungselementes an dem Feuchtreinigungsgerät. Es sind weniger Montagemittel und weniger Handgriffe notwendig, um das gemeinsame Element zu montieren. Die bogenförmige Ausgestaltung des gemeinsamen Elementes eignet sich insbesondere, um auf der von der Reinigungswalze weg weisenden konvex gekrümmten Seite einen Aufprall der umgeknickten freien Enden der Fasern auf das Führungselement zu ermöglichen und somit durch das Aufprallen der freien Enden auf dem Führungselement einen zusätzlichen Reinigungseffekt zu erzielen. Die konvexe Krümmung sorgt darüber hinaus dafür, dass die Flüssigkeit bzw. der Schmutz der Schwerkraft folgend entlang der negativen Steigung der Fläche zu dem Flüssigkeitskanal geführt werden kann. Die entgegengesetzte, konkav gekrümmte Seite des gemeinsamen Elementes, welche zu der Reinigungswalze hinweist, ist vorzugsweise konkav gekrümmt, damit sich die freien Enden der Fasern bei weitergeführter Rotation der Reinigungswalze wieder möglichst frühzeitig unter dem gemeinsamen Element aufrichten können.Furthermore, it is proposed that the braking element and the guide element are designed as a common element. In particular, it is proposed that the braking element and the guide element are formed together as an arcuate element which is convexly curved on a side facing away from the cleaning roller and is concavely curved on a side pointing towards the cleaning roller. Through the One-piece design of the braking element with the guide element creates a fluid-tight connection between the braking element and the guide element, so that liquid thrown off at the braking element by the fibers of the cleaning pad cannot flow between the braking element and the guide element, in particular dripping onto the cleaning roller. In addition, the one-piece design also offers advantages when mounting the braking element or the guide element on the wet cleaning device. Fewer assembly means and fewer handles are required to assemble the common element. The arcuate configuration of the common element is particularly suitable for allowing the bent free ends of the fibers to impact the guide element on the convex curved side facing away from the cleaning roller and thus to achieve an additional cleaning effect by the free ends hitting the guide element . The convex curvature also ensures that the liquid or the dirt can be guided to the liquid channel along the negative slope of the surface, following the force of gravity. The opposite, concavely curved side of the common element, which points towards the cleaning roller, is preferably concavely curved so that the free ends of the fibers can straighten up again as early as possible under the common element when the cleaning roller continues to rotate.

Des Weiteren wird vorgeschlagen, dass die Aufprallkante des Abbremselementes konvex gekrümmt ist. Dadurch werden die Fasern des Reinigungsbelages zum einen möglichst schonend um das Abbremselement bzw. die Aufprallkante geführt, sodass die Lebensdauer des Reinigungsbelags erhöht ist, und zum anderen ein Umlenken der freien Enden der Fasern in Richtung des Führungselementes erleichtert.It is also proposed that the impact edge of the braking element is convexly curved. As a result, the fibers of the cleaning pad are guided as gently as possible around the braking element or the impact edge, so that the service life of the cleaning pad is increased and, on the other hand, it facilitates deflecting the free ends of the fibers in the direction of the guide element.

Die Aufprallkante des Abbremselementes weist vorzugsweise eine Höhe von ungefähr einem Drittel einer Faserlänge der Fasern auf. Dadurch kann in radialer Richtung (bezogen auf die Walzenachse) sowohl unter als auch über der Aufprallkante ein ausreichender Abstand erreicht werden, welcher zum Zurückziehen der Fasern unter dem Abbremselement bzw. zum Umlenken der freien Enden der Fasern über dem Abbremselement geeignet ist.The impact edge of the braking element preferably has a height of approximately one third of a fiber length of the fibers. As a result, a sufficient distance can be achieved in the radial direction (based on the roller axis) both below and above the impact edge, which distance is suitable for retracting the fibers under the braking element or for deflecting the free ends of the fibers over the braking element.

Zudem wird vorgeschlagen, dass die Aufprallkante in bezogen auf die Walzenachse radialer Richtung einen Abstand zu Faserwurzeln der Fasern von einem Viertel bis ein halb einer Faserlänge der Fasern aufweist. Dieser Abstand ist ausreichend, um die Fasern zwischen dem Abbremselement und den Faserwurzeln der Fasern hindurchzuziehen, ohne dass eine Beschädigung an dem Reinigungsbelag hervorgerufen wird. Andererseits ist dieser Abstand so gering, dass eine zusätzliche Abstreifwirkung der Fasern zwischen Reinigungswalze und Abbremselement erreicht werden kann.In addition, it is proposed that the impact edge be at a distance from the fiber roots of the fibers of a quarter to a half of a fiber length of the fibers in the radial direction with respect to the roller axis. This distance is sufficient to pull the fibers between the braking element and the fiber roots of the fibers without causing damage to the cleaning pad. On the other hand, this distance is so small that an additional wiping effect of the fibers between the cleaning roller and the braking element can be achieved.

Es wird zudem vorgeschlagen, dass sich das Führungselement in Rotationsrichtung der Reinigungswalze ausgehend von dem Abbremselement zu dem Flüssigkeitskanal erstreckt, insbesondere eine Verlängerung einer Kanalwandung des Flüssigkeitskanals bildet. Durch diese Ausgestaltung ist ein verlustfreier Transport der Flüssigkeit bzw. des Schmutzes von dem Abbremselement in den Flüssigkeitskanal möglich. Das Führungselement ist somit vorzugsweise ein Endbereich einer Kanalwandung, welcher wie zuvor vorgeschlagen eine Bogenform aufweist.It is also proposed that the guide element extends in the direction of rotation of the cleaning roller, starting from the braking element to the liquid channel, in particular forming an extension of a channel wall of the liquid channel. This configuration enables loss-free transportation of the liquid or dirt from the braking element into the liquid channel. The guide element is thus preferably an end region of a channel wall which, as previously proposed, has an arc shape.

Des Weiteren wird vorgeschlagen, dass das Führungselement und/oder das Abbremselement relativ zu der Reinigungswalze verlagerbar, insbesondere schwenkbar, gelagert ist, insbesondere an einer Kanalwandung des Flüssigkeitskanals gelagert ist. Das Abbremselement bzw. das Führungselement wird üblicherweise nur während des Regenerationsbetriebs der Reinigungswalze benötigt. Daher empfiehlt es sich, das Abbremselement vor dem Durchführen eines Wischbetriebs aus dem Reinigungsbelag der Reinigungswalze zu entfernen, d.h. von der Reinigungswalze weg zu verlagern. Das Führungselement sollte dementsprechend ebenfalls von der Reinigungswalze weg verlagert werden. Sofern das Abbremselement und das Führungselement als gemeinsames Element ausgebildet sind, erfolgt die Verlagerung entsprechend gleichzeitig. Das Abbremselement und/oder das Führungselement ist verlagerbar an dem Feuchtreinigungsgerät angeordnet, sodass dieses bspw. zu der Reinigungswalze hin geschwenkt und von der Reinigungswalze weg geschwenkt werden kann. Hierzu kann entsprechend ein Schwenkarm vorgesehen sein. Alternativ ist es selbstverständlich auch möglich, dass die Verlagerung auf andere Art und Weise erfolgt, bspw. durch eine lineare Verschiebung des Abbremselementes bzw. des Führungselementes. In dem Fall, dass das Führungselement und das Abbremselement wie zuvor vorgeschlagen als gemeinsames Element ausgebildet sind, genügt selbstverständlich eine einzige Verlagerungsbewegung, um sowohl das Führungselement als auch das Abbremselement relativ zu der Reinigungswalze zu verlagern.Furthermore, it is proposed that the guide element and / or the braking element is mounted such that it can be displaced, in particular pivoted, relative to the cleaning roller, in particular is mounted on a channel wall of the liquid channel. The braking element or the guide element is usually only required during the regeneration operation of the cleaning roller. It is therefore advisable to remove the braking element from the cleaning surface of the cleaning roller before carrying out a wiping operation, ie to move it away from the cleaning roller. Accordingly, the guide element should also be moved away from the cleaning roller. If the braking element and the guide element are designed as a common element, the displacement accordingly takes place simultaneously. The braking element and / or the guide element is displaceably arranged on the wet cleaning device, so that it can be pivoted, for example, towards the cleaning roller and pivoted away from the cleaning roller. For this purpose, a swivel arm can be provided accordingly. Alternatively, it is of course also possible for the displacement to take place in a different way, for example by a linear displacement of the braking element or of the guide element. In the event that the guide element and the braking element are designed as a common element as previously proposed, a single displacement movement is of course sufficient to move both the guide element and the braking element relative to the cleaning roller.

Des Weiteren wird vorgeschlagen, dass dem Abbremselement und/oder dem Führungselement mindestens eine Düse zum Ausbringen von Flüssigkeit auf die Reinigungswalze zugeordnet ist, wobei das Abbremselement und/oder das Führungselement relativ zu einer Flüssigkeitsaustrittsrichtung der Düse in einem Winkel zwischen 90° und 170°, insbesondere zwischen 90° und 105° anordbar ist, so dass aus der Düse beschleunigt gegen das Abbremselement und/oder das Führungselement ausgebrachte Flüssigkeit der Schwerkraft folgend an dem Abbremselement und/oder dem Führungselement entlang die Reinigungswalze erreicht. Durch diese vorzugsweise Ausgestaltung stellt das Abbremselement und/oder das Führungselement nun eine Führungsfläche zur Verfügung, an welcher Flüssigkeit von einer Düse zu der Reinigungswalze strömen kann. Die Führungsfläche des Abbremselementes bzw. des Führungselementes ist der Reinigungswalze und damit auch dem Reinigungsbelag zugewandt. Die aus der Düse austretende Flüssigkeit wird dadurch nicht mehr direkt auf die Reinigungswalze aufgetragen, sondern vielmehr zunächst auf das Abbremselement und/oder das Führungselement und von dort aus auf die Reinigungswalze. Unter dem Begriff Flüssigkeit wird dabei auch ein Dampf, Flüssigkeitstropfen, Sprühnebel oder dergleichen verstanden. Vorzugsweise ist die Düse relativ zu dem Abbremselement bzw. dem Führungselement so angeordnet, dass die die Düse in eine Flüssigkeitsaustrittsrichtung beschleunigt verlassende Flüssigkeit auf das Abbremselement und/oder das Führungselement trifft und dort in Richtung der Reinigungswalze fließt, wobei die Flüssigkeit nach dem Auftreffen auf das Abbremselement bzw. das Führungselement in einem Flüssigkeitsfilm aufgefächert wird. Die die Düse verlassende Flüssigkeit ist vorteilhaft mittels einer Pumpe beschleunigt und tritt in eine Flüssigkeitsaustrittsrichtung aus der Düse aus, welche von einer senkrechten Richtung abweicht. Die Flüssigkeit trifft im Wesentlichen in dieser Richtung auf das Abbremselement und/oder das Führungselement auf, wobei die von der Pumpe auf die Flüssigkeit ausgeübte Kraft ausreicht, damit die Flüssigkeit das Abbremselement bzw. das Führungselement erreichen kann. An dem Abbremselement bzw. dem Führungselement erzeugt die Flüssigkeit einen Flüssigkeitsfleck von welchem ausgehend sich Anteile der Flüssigkeit im Wesentlichen radial in alle Richtungen bewegen, bspw. auch entgegen der Schwerkraft. Die Flüssigkeit orientiert sich mit größer werdendem Abstand zu der Düse der Richtung der Schwerkraft folgend zunehmend senkrechter, wodurch die Auffächerung der Flüssigkeit erfolgt. Durch die Auffächerung des Flüssigkeitsstrahls lässt sich die Reinigungswalze über ihre gesamte Längserstreckung homogen befeuchten. Während der Befeuchtung rotiert die Reinigungswalze bevorzugt, so dass eine homogene Befeuchtung über die gesamte Umfangsfläche der Reinigungswalze erreicht werden kann. Damit sich die auf das Abbremselement und/oder das Führungselement aufgebrachte Flüssigkeit möglichst breit auffächert und somit eine möglichst breite Fläche der Reinigungswalze befeuchten kann, sollte die Flüssigkeit bevorzugt nahezu senkrecht auf das Abbremselement und/oder das Führungselement aufgebracht werden. Zwischen dem Abbremselement bzw. dem Führungselement und der Flüssigkeitsaustrittsrichtung der Düse empfiehlt sich ein Winkel zwischen 90° und 170°, insbesondere jedoch zwischen 90° und 105°. In der Praxis hat sich herausgestellt, dass ein Winkel größer als 105° zu einer relevanten Verkleinerung der aufgefächerten Breite des Flüssigkeitsstrahls führt. Insbesondere in Kombination mit einer zuvor vorgeschlagenen Verlagerbarkeit des Abbremselementes und/oder des Führungselementes relativ zu der Reinigungswalze lässt sich ein geeigneter Winkel und ein geeigneter Abstand zwischen der Oberfläche der Reinigungswalze und dem Abbremselement bzw. dem Führungselement einstellen.Furthermore, it is proposed that at least one nozzle for dispensing liquid onto the cleaning roller is assigned to the braking element and / or the guide element, the braking element and / or the guide element being at an angle between 90 ° and 170 ° relative to a liquid outlet direction of the nozzle, can be arranged in particular between 90 ° and 105 °, so that liquid discharged from the nozzle against the braking element and / or the guide element, following gravity, reaches the cleaning roller along the braking element and / or the guide element. With this preferred configuration, the braking element and / or the guide element now provides a guide surface on which liquid flows from a nozzle to the cleaning roller can flow. The guide surface of the braking element or of the guide element faces the cleaning roller and thus also the cleaning covering. As a result, the liquid emerging from the nozzle is no longer applied directly to the cleaning roller, but rather first to the braking element and / or the guide element and from there to the cleaning roller. The term liquid is also understood to mean a vapor, liquid drop, spray mist or the like. The nozzle is preferably arranged relative to the braking element or the guide element in such a way that the liquid leaving the nozzle accelerating in a liquid exit direction hits the braking element and / or the guide element and flows there in the direction of the cleaning roller, the liquid after impinging on the Braking element or the guide element is fanned out in a liquid film. The liquid leaving the nozzle is advantageously accelerated by means of a pump and emerges from the nozzle in a liquid exit direction which deviates from a vertical direction. The liquid essentially strikes the braking element and / or the guide element in this direction, the force exerted by the pump on the liquid being sufficient for the liquid to reach the braking element or the guide element. The liquid generates a liquid spot on the braking element or the guide element, from which portions of the liquid move essentially radially in all directions, for example also against gravity. As the distance to the nozzle increases, the liquid orientates itself more and more vertically following the direction of gravity, as a result of which the liquid is fanned out. By fanning out the liquid jet, the cleaning roller can be moistened homogeneously over its entire longitudinal extent. The cleaning roller preferably rotates during the moistening, so that homogeneous moistening can be achieved over the entire circumferential surface of the cleaning roller. So that the liquid applied to the braking element and / or the guide element fanned out as widely as possible and thus can moisten the widest possible area of the cleaning roller, the liquid should preferably be applied almost perpendicularly to the braking element and / or the guide element. An angle between 90 ° and 170 ° is recommended between the braking element or the guide element and the liquid outlet direction of the nozzle, but in particular between 90 ° and 105 °. In practice it has been found that an angle greater than 105 ° leads to a relevant reduction in the fanned-out width of the liquid jet. In particular in combination with a previously proposed displaceability of the braking element and / or the guide element relative to the cleaning roller, a suitable angle and a suitable distance between the surface of the cleaning roller and the braking element or the guide element can be set.

Neben dem vorgeschlagenen Feuchtreinigungsgerät wird mit der Erfindung ebenso ein Verfahren zum Betrieb eines Feuchtreinigungsgerätes vorgeschlagen, bei welchem Flüssigkeit und/oder Schmutz während eines Regenerationsbetriebs von einem Reinigungsbelag einer um eine Walzenachse rotierenden Reinigungswalze des Feuchtreinigungsgerätes entfernt werden, und wobei ein Abbremselement und ein in Rotationsrichtung der Reinigungswalze hinter dem Abbremselement angeordnetes Führungselement zum Entfernen und Zuführen der Flüssigkeit und/oder des Schmutzes von der Reinigungswalze zu einem Flüssigkeitskanal so relativ zu der Reinigungswalze angeordnet werden, dass eine Aufprallkante des Abbremselementes soweit zwischen Fasern des Reinigungsbelages ragt, dass freie Enden der Fasern in radialer Richtung nach außen über die Aufprallkante hinwegragen und bei einem Aufprall auf die Aufprallkante in Richtung des Führungselementes umgelenkt werden. Die Merkmale und Vorteile des erfindungsgemäßen Verfahrens ergeben sich wie zuvor in Bezug auf das Feuchtreinigungsgerät beschrieben.In addition to the proposed wet cleaning device, the invention also proposes a method for operating a wet cleaning device in which liquid and / or dirt are removed from a cleaning pad of a cleaning roller of the wet cleaning device rotating about a roller axis during a regeneration operation, and wherein a braking element and one in the direction of rotation of the Cleaning roller arranged behind the braking element for removing and supplying the liquid and / or dirt from the cleaning roller to a liquid channel relative to the cleaning roller such that an impact edge of the braking element protrudes so far between the fibers of the cleaning pad that free ends of the fibers are radial Project outwards beyond the impact edge and be deflected in the direction of the guide element in the event of an impact on the impact edge. The features and advantages of the method according to the invention result as previously described in relation to the wet cleaning device.

Insbesondere wird vorgeschlagen, dass die an der Aufprallkante umgelenkten freien Enden der Fasern auf das Führungselement prallen, wodurch sich neben dem Abschleudern durch das Stoppen der Fasern an der Aufprallkante zudem eine Reinigungswirkung durch das Aufschlagen der freien Enden auf dem Führungselement ergibt.In particular, it is proposed that the free ends of the fibers deflected at the impact edge collide with the guide element, which, in addition to being thrown off by stopping the fibers at the impact edge, also results in a cleaning effect by hitting the free ends on the guide element.

Schließlich wird vorgeschlagen, dass durch den Aufprall auf die Aufprallkante und/oder auf das Führungselement von den Fasern abgeschleuderte Flüssigkeit und/oder Schmutz entlang des Führungselementes in den Flüssigkeitskanal geleitet werden. Insbesondere durch eine zuvor vorgeschlagene einteilige Ausbildung des Abbremselementes mit dem Führungselement und ggf. sogar eine fluiddichte Verbindung des Führungselementes mit dem Flüssigkeitskanal kann ein Abtropfen der abgeschleuderten Flüssigkeit und/oder des Schmutzes zurück auf die Reinigungswalze verhindert werden, sodass die Flüssigkeit bzw. der Schmutz ausschließlich von der Aufprallkante über das Führungselement zu dem Flüssigkeitskanal strömt.Finally, it is proposed that liquid and / or dirt thrown off the fibers by the impact on the impact edge and / or on the guide element be guided along the guide element into the liquid channel. In particular, a previously proposed one-piece design of the braking element with the guide element and possibly even a fluid-tight connection of the guide element with the liquid channel can prevent the spun off liquid and / or the dirt dripping back onto the cleaning roller, so that the liquid or the dirt only flows from the impact edge over the guide element to the liquid channel.

Grundsätzlich sind im Sinne der Erfindung als Feuchtreinigungsgeräte alle solchen Geräte zu verstehen, welche ausschließlich oder unter anderem eine Feuchtreinigung durchführen können. Hierzu zählen zum einen die handgeführten und selbsttätig verfahrbaren Feuchtreinigungsgeräte, insbesondere auch Reinigungsroboter, und zum anderen kombinierte Trocken- und FeuchtReinigungsgeräte, welche sowohl eine Feuchtreinigung als auch eine Trockenreinigung durchführen können. Darüber hinaus sind neben üblichen Bodenreinigungsgeräten zur Reinigung eines Fußbodens auch Feuchtreinigungsgeräte zur Reinigung von Überbodenflächen im Sinne der Erfindung gemeint. Zu diesen gehören bspw. Geräte zum Fenster putzen und dergleichen.Basically, in the sense of the invention, wet cleaning devices are to be understood as all those devices which can exclusively or, among other things, carry out wet cleaning. On the one hand, this includes the hand-held and automatically movable wet cleaning devices, in particular also cleaning robots, and on the other hand combined dry and wet cleaning devices, which can perform both wet cleaning and dry cleaning. In addition to conventional floor cleaning devices for cleaning a floor, this also means wet cleaning devices for cleaning surface areas in the sense of the invention. These include, for example, devices for cleaning windows and the like.

Beschreibung der AusführungsformenDescription of the embodiments

Figur 1 zeigt ein Feuchtreinigungsgerät 1, welches hier als handgeführtes Feuchtreinigungsgerät 1 mit einem Basisgerät 12 und einem Vorsatzgerät 13 ausgebildet ist. Das Vorsatzgerät 13 ist abnehmbar an dem Basisgerät 12 gehalten. Das Basisgerät 12 weist zudem einen Stiel 14 auf, welcher hier bspw. teleskopierbar ausgebildet ist, sodass ein Nutzer des Feuchtreinigungsgerätes 1 die Länge des Stiels 14 an seine Körpergröße anpassen kann. An dem Stiel 14 ist des Weiteren ein Handgriff 15 angeordnet, an welchem der Nutzer das Feuchtreinigungsgerät 1 während eines üblichen Wischbetriebs führen, d.h. über eine zu reinigende Fläche schieben, kann. Während des Wischbetriebs führt der Nutzer das Feuchtreinigungsgerät 1 üblicher Weise in entgegengesetzten Bewegungsrichtungen x über die zu reinigende Fläche. Dabei schiebt er das Feuchtreinigungsgerät 1 abwechselnd von sich weg bzw. zieht dieses zu sich hin. Figure 1 shows a wet cleaning device 1, which is designed here as a hand-held wet cleaning device 1 with a basic device 12 and an attachment device 13. The attachment 13 is detachably held on the base device 12. The base device 12 also has a handle 14, which here is, for example, telescopic, so that a user of the wet cleaning device 1 can adapt the length of the handle 14 to his body size. A handle 15 is also arranged on the handle 14, on which the user can guide the wet cleaning device 1 during a normal wiping operation, ie slide it over a surface to be cleaned. During the wiping operation, the user usually guides the wet cleaning device 1 in opposite directions of movement x over the surface to be cleaned. He alternately pushes the wet cleaning device 1 away from him or pulls it towards himself.

Das Vorsatzgerät 13 weist eine Reinigungswalze 3 auf sowie einen Einfüllstutzen 16 auf, durch welchen Flüssigkeit in einen Flüssigkeitstank (nicht dargestellt) eingefüllt werden kann. Die in dem Flüssigkeitstank gespeicherte Flüssigkeit dient zur äußeren Befeuchtung der Reinigungswalze 3.The attachment 13 has a cleaning roller 3 and a filler neck 16, through which liquid can be filled into a liquid tank (not shown). The liquid stored in the liquid tank serves for the external moistening of the cleaning roller 3.

Die Reinigungswalze 3 ist um eine Walzenachse 2 rotierbar innerhalb des Vorsatzgerätes 13 gelagert. Während eines Wischbetriebs rotiert die Reinigungswalze 3 um die Walzenachse 2, sodass die Umfangsfläche der Reinigungswalze 3 fortlaufend auf der zu reinigenden Fläche abrollt. Die Reinigungswalze 3 ist üblicher Weise mit einem Reinigungsbelag 4 umwickelt, ggf. unter Zwischenlage eines zusätzlich flüssigkeitsspeichernden Schwammkörpers. Der Reinigungsbelag 4 ist hier bspw. ein textiles Reinigungstuch, zwischen dessen Fasern 6 Flüssigkeit aufgenommen werden kann.The cleaning roller 3 is rotatably mounted about a roller axis 2 within the attachment 13. During a wiping operation, the cleaning roller 3 rotates about the roller axis 2, so that the peripheral surface of the cleaning roller 3 continuously rolls on the surface to be cleaned. The cleaning roller 3 is usually wrapped with a cleaning covering 4, possibly with the interposition of an additional liquid-storing sponge body. The cleaning covering 4 is here, for example, a textile cleaning cloth, between whose fibers 6 liquid can be taken up.

Während des Wischbetriebs lagert sich fortwährend Schmutz an der Reinigungswalze 3, d.h. insbesondere dem Reinigungsbelag 4, an. Daher kann nach einer gewissen Betriebsdauer eine Regeneration der Reinigungswalze 3 erforderlich sein, wobei während eines Regenerationsbetriebs Schmutz und mit Schmutz beaufschlagte Flüssigkeit von der Reinigungswalze 3 entfernt werden.During the wiping operation, dirt is continuously deposited on the cleaning roller 3, i.e. especially the cleaning surface 4. It may therefore be necessary to regenerate the cleaning roller 3 after a certain operating time, dirt and contaminated liquid being removed from the cleaning roller 3 during a regeneration operation.

Die Figuren 2 bis 4 zeigen jeweils die Reinigungswalze 3 mit dem Reinigungsbelag 4, welcher eine Vielzahl von Fasern 6 aufweist. Die Fasern 6 sind zu Anschauungszwecken nur skizziert, da die Anzahl der Fasern 6 in der Praxis selbstverständlich deutlich größer ist. Der Reinigungsbelag 4 ist hier bspw. ein Mikrofasertextil. Zwischen die Fasern 6 des Reinigungsbelags 4 greift ein einteilig ausgebildetes Element aus einem Abbremselement 5 und einem Führungselement 9 ein. Das Abbremselement 5 weist eine Aufprallkante 7 auf, welche gekrümmt ausgebildet ist. Die Aufprallkante 7 steht einer Rotationsrichtung r der Reinigungswalze 3 im Wesentlichen frontal entgegen, sodass die sich um die Walzenachse 2 bewegenden Fasern 6 gegen den gekrümmten Stirnbereich des Abbremselementes 5 prallen. In eine ausgehend von der Walzenachse 2 radiale Richtung weist die Aufprallkante 7 des Abbremselementes 5 eine Höhe auf, welche ungefähr einem Drittel einer Faserlänger L der Fasern 6 entspricht. Zu den Faserwurzeln 19 der Fasern 6, welche in dem Reinigungsbelag 4 befestigt sind, weist das Abbremselement 5 in radialer Richtung ungefähr einen Abstand z von ebenfalls einem Drittel einer Faserlänge L der Fasern 6 auf. Schließlich verbleibt in radialer Richtung ausgehend von der Walzenachse 2 ein freies Ende 8 der Fasern 6, welches über die Aufprallkante 7 des Abbremselementes 5 hinausragt. Das Führungselement 9 ist einteilig mit dem Abbremselement 5 ausgebildet, wobei das Abbremselement 5 einen in die Fasern 6 ragenden Endbereich bildet und das Führungselement 9 sich in Richtung eines Flüssigkeitskanals 10 des Feuchtreinigungsgerätes 1 erstreckt, wie später noch zu den Figuren 5 bis 8 erläutert wird. Das Abbremselement 5 und das Führungselement 9 bilden gemeinsam ein bogenförmiges Element, welches auf einer von der Reinigungswalze 3 weg weisenden Seite konvex gekrümmt ist und auf einer zu der Reinigungswalze 3 hin weisenden Seite konkav gekrümmt ist.The Figures 2 to 4 each show the cleaning roller 3 with the cleaning covering 4, which has a multiplicity of fibers 6. The fibers 6 are only outlined for illustrative purposes, since the number of fibers 6 is of course significantly larger in practice. The cleaning covering 4 is here, for example, a microfiber textile. Between the fibers 6 of the cleaning covering 4, a one-piece element consisting of a braking element 5 and a guide element 9 engages. The braking element 5 has an impact edge 7 which is curved. The impact edge 7 essentially opposes a direction of rotation r of the cleaning roller 3 so that the fibers 6 moving about the roller axis 2 collide with the curved end region of the braking element 5. In a radial direction starting from the roller axis 2, the impact edge 7 of the braking element 5 has a height which corresponds to approximately one third of a fiber length L of the fibers 6. To the fiber roots 19 of the fibers 6, which are fastened in the cleaning covering 4, the braking element 5 has a radial distance z of approximately one third of a fiber length L of the fibers 6. Finally, in the radial direction, starting from the roller axis 2, there remains a free end 8 of the fibers 6, which projects beyond the impact edge 7 of the braking element 5. The guide element 9 is formed in one piece with the braking element 5, the braking element 5 forming an end region protruding into the fibers 6 and the guide element 9 extending in the direction of a liquid channel 10 of the wet cleaning device 1, as will be explained later on Figures 5 to 8 is explained. The braking element 5 and the guide element 9 together form an arcuate element, which on one of the cleaning roller 3 facing side is convexly curved and is concave on a side facing the cleaning roller 3.

Zunächst wird in Bezug auf die Figuren 2 bis 4 die Funktion des Abbremselementes 5 und des Führungselementes 9 bei einem Kontakt der Fasern 6 mit dem Abbremselement 5 erläutert, wobei die Figuren 2 bis 4 unterschiedliche Zeitpunkte während eines Regenerationsbetriebs des Feuchtreinigungsgerätes 1 zeigen, in welchen die Reinigungswalze 3 in Rotationsrichtung r aufeinanderfolgende Rotationsstellungen einnimmt.First, in terms of Figures 2 to 4 the function of the braking element 5 and the guide element 9 explained when the fibers 6 come into contact with the braking element 5, the Figures 2 to 4 show different times during a regeneration operation of the wet cleaning device 1, in which the cleaning roller 3 assumes successive rotational positions in the direction of rotation r.

Figur 2 zeigt einen ersten Zeitpunkt, zu welchem eine Faser 6, welche noch annähernd gestreckt ist (bezogen auf eine radiale Richtung ausgehend von der Walzenachse 2) gerade auf die Aufprallkante 7 des Abbremselementes 5 aufprallt. Andere Fasern 6 des Reinigungsbelages 4 befinden sich darüber hinaus zu demselben Zeitpunkt unterhalb des Führungselementes 9 (in Rotationsrichtung r hinter dem Abbremselement 5) bzw. in mechanisch unbelasteter gestreckter Form in Rotationsrichtung r vor dem Abbremselement 5. Figure 2 shows a first point in time at which a fiber 6, which is still approximately stretched (in relation to a radial direction starting from the roller axis 2), just hits the impact edge 7 of the braking element 5. Other fibers 6 of the cleaning pad 4 are also located at the same time below the guide element 9 (in the direction of rotation r behind the braking element 5) or in a mechanically unloaded stretched form in the direction of rotation r in front of the braking element 5.

Die aktuell auf die Aufprallkante 7 aufprallende Faser 6 wird wie in Figur 3 dargestellt mit ihrem freien Ende 8 um die Aufprallkante 7 umgelenkt, wobei das freie Ende 8 der Faser 6 nun nicht mehr mit einer ersten Rotationsgeschwindigkeit um die Walzenachse 2 rotiert, sondern demgegenüber beschleunigt um ein neues Rotationszentrum, welches nun durch die radial nach außen weisende Seite der Aufprallkante 7 gebildet ist. Da der Rotationsradius der Faser 6 nunmehr auf die Länge des freien Endes 8 der Faser 6 reduziert wurde, rotiert das freie Ende 8 mit erhöhter Geschwindigkeit um den neuen Rotationsmittelpunkt und wird peitschenartig in Rotationsrichtung r umgelenkt, d.h. auf das Führungselement 9 zu. In einem Endstadium dieser Bewegung schlägt das freie Ende 8 der Faser 6 auf die konvex gekrümmte Oberfläche des Führungselementes 9 auf und schleudert dabei zusätzlich Flüssigkeit und/oder Schmutz von der Faser 6 ab. Die Flüssigkeit bzw. der Schmutz wird durch die Bewegungsenergie in Rotationsrichtung r entlang der konvexen Oberseite des Führungselementes 9 geführt, wobei die Strömung in Richtung des Flüssigkeitskanals 10 des Feuchtreinigungsgerätes 1 durch die abfallende Flanke des Führungselementes 9 begünstigt ist.The fiber 6 currently impacting on the impact edge 7 is as in Figure 3 shown with its free end 8 deflected around the impact edge 7, the free end 8 of the fiber 6 no longer rotating at a first rotational speed about the roller axis 2, but instead accelerating around a new center of rotation, which is now through the radially outward-facing side the impact edge 7 is formed. Since the radius of rotation of the fiber 6 has now been reduced to the length of the free end 8 of the fiber 6, the free end 8 rotates at an increased speed around the new center of rotation and is deflected like a whip in the direction of rotation r, ie towards the guide element 9. In an end stage of this movement, the free end 8 of the fiber 6 strikes the convexly curved surface of the guide element 9 and additionally throws off liquid and / or dirt from the fiber 6. The liquid or the dirt is guided by the kinetic energy in the direction of rotation r along the convex upper side of the guide element 9, the flow in the direction of the liquid channel 10 of the wet cleaning device 1 being favored by the falling flank of the guide element 9.

Figur 4 zeigt einen nachfolgenden Zeitpunkt, zu welchem die zuvor auf das Führungselement 9 aufgeschlagene Faser 6 bei fortgeschrittener Rotation der Reinigungswalze 3 wieder von dem Abbremselement 5 zurückgezogen wird und nun zwischen dem Abbremselement 5 und dem Bereich der Faserwurzeln 19 hindurchgezogen wird. Dadurch ergibt sich ein zusätzlicher Abstreifeffekt, welcher ggf. noch auf der Faser 6 befindliche Flüssigkeit bzw. Schmutz abstreift. Bei ausgehend von Figur 4 weiter geführter Rotation stellt sich die Faser 6 unter dem Führungselement 9 wieder auf, wobei die konkave Krümmung der zu der Reinigungswalze 3 gewandten Seite des Führungselementes 9 einen entsprechenden Freiraum für das Aufrichten der Fasern 6 bietet. Figure 4 shows a subsequent point in time at which the fiber 6 previously struck on the guide element 9 is withdrawn again from the braking element 5 when the cleaning roller 3 rotates and is now pulled through between the braking element 5 and the region of the fiber roots 19. This results in an additional wiping effect, which wipes off any liquid or dirt still on the fiber 6. Starting from Figure 4 Continued rotation, the fiber 6 rises again under the guide element 9, the concave curvature of the side of the guide element 9 facing the cleaning roller 3 providing adequate space for straightening the fibers 6.

Die Figuren 5 und 6 zeigen die Anordnung des Führungselementes 9 innerhalb des Vorsatzgerätes 13 des Feuchtreinigungsgerätes 1. Das Führungselement 9 ist mit seinem dem Abbremselement 5 abgewandten Endbereich an einer Kanalwandung 11 des Flüssigkeitskanals 10 schwenkbar gelagert, nämlich um eine Schwenkachse 17. Das Führungselement 9 und somit auch das einteilig mit dem Führungselement 9 ausgebildete Abbremselement 5 können dadurch um die Schwenkachse 17 relativ zu der Reinigungswalze 3 verlagert werden. In Abhängigkeit von dem jeweiligen Betriebsmodus des Feuchtreinigungsgerätes 1 können das Abbremselement 5 und das Führungselement 9 somit entweder zwischen die Fasern 6 des Reinigungsbelages 4 eintauchen oder von der Reinigungswalze 3 weggeschwenkt sein.The Figures 5 and 6 show the arrangement of the guide element 9 within the attachment 13 of the wet cleaning device 1. The guide element 9 is pivotally mounted with its end region facing away from the braking element 5 on a channel wall 11 of the liquid channel 10, namely about a pivot axis 17. The guide element 9 and thus also in one piece the braking element 5 formed in the guide element 9 can thereby be displaced relative to the cleaning roller 3 about the pivot axis 17. Depending on the respective operating mode of the wet cleaning device 1, the braking element 5 and the guide element 9 can thus either be immersed between the fibers 6 of the cleaning pad 4 or pivoted away from the cleaning roller 3.

Während eines Regenerationsbetriebs des Feuchtreinigungsgerätes 1, bei welchem Flüssigkeit und/oder Schmutz von der Reinigungswalze 3 entfernt und in den Flüssigkeitskanal 10 abgeleitet werden sollen, ist das Abbremselement 5 wie in den Figuren 5 und 6 dargestellt zwischen die Fasern 6 des Reinigungsbelages 4 geschoben, sodass der zuvor in Bezug auf die Figuren 2 bis 4 dargestellte Regenerationsvorgang zur Reinigung des Reinigungsbelags 4 stattfinden kann.During a regeneration operation of the wet cleaning device 1, in which liquid and / or dirt are to be removed from the cleaning roller 3 and discharged into the liquid channel 10, the braking element 5 is as in FIGS Figures 5 and 6 Shown between the fibers 6 of the cleaning pad 4, so that the previously in relation to the Figures 2 to 4 shown regeneration process for cleaning the cleaning surface 4 can take place.

Während eines üblichen Wischbetriebs des Feuchtreinigungsgerätes 1, bei welchem die Reinigungswalze 3 auf eine zu reinigende Fläche aufgesetzt ist und Schmutz von der zu reinigenden Fläche aufnimmt, sind das Abbremselement 5 und das Führungselement 9 hingegen von der Reinigungswalze 3 weggeschwenkt, wobei es sich insbesondere anbietet, dass das Führungselement 9 dabei - wie später noch in Bezug auf Figur 8 dargestellt - den Flüssigkeitskanal 10 verschließt, sodass Schmutz und/oder Flüssigkeit nicht aus dem Flüssigkeitskanal 10 zurück in Richtung der Reinigungswalze 3 gelangen können.During a normal wiping operation of the wet cleaning device 1, in which the cleaning roller 3 is placed on a surface to be cleaned and picks up dirt from the surface to be cleaned, the braking element 5 and the guide element 9, on the other hand, are pivoted away from the cleaning roller 3, which is particularly useful, that the guide element 9 - as later with reference to Figure 8 shown - closes the liquid channel 10 so that dirt and / or liquid cannot get back out of the liquid channel 10 in the direction of the cleaning roller 3.

Während des Regenerationsbetriebs ist das Abbremselement 5 unbeweglich zwischen den Fasern 6 des Reinigungsbelags 4 angeordnet und die Fasern 6 bewegen sich relativ zu dem Abbremselement 5. Das Führungselement 9 bildet dabei eine Verlängerung der Kanalwandung 11, sodass von den Fasern 6 abgeschleuderte Flüssigkeit direkt und im Wesentlichen ohne Verluste von dem Abbremselement 5 in den Flüssigkeitskanal 10 gelangen kann. Ein Abtropfen von Flüssigkeit zurück auf die Reinigungswalze 3 ist somit wirksam verhindert.During the regeneration operation, the braking element 5 is immovably arranged between the fibers 6 of the cleaning pad 4 and the fibers 6 move relative to the braking element 5. The guide element 9 forms an extension of the channel wall 11, so that liquid flung off by the fibers 6 is direct and essentially can get into the liquid channel 10 without losses from the braking element 5. Dripping of liquid back onto the cleaning roller 3 is thus effectively prevented.

Zur Verlagerung des Führungselementes 9 relativ zu der Reinigungswalze 3 greift ein Hebel 20 an dem Führungselement 9 an. Ein Nutzer des Feuchtreinigungsgerätes 1 kann bspw. manuell an dem Hebel 20 angreifen und eine Verlagerung des Führungselementes 9 bewirken. Alternativ ist es jedoch auch möglich, dass eine automatische Betätigung des Hebels 20 bspw. mittels eines Stellmotors, erfolgt, wenn von einem Wischbetrieb in einen Regenerationsbetrieb des Feuchtreinigungsgerätes 1 geschaltet wird.To move the guide element 9 relative to the cleaning roller 3, a lever 20 engages the guide element 9. A user of the wet cleaning device 1 can, for example, manually engage the lever 20 and cause the guide element 9 to be displaced. However, it is an alternative it is also possible for the lever 20 to be actuated automatically, for example by means of a servomotor, when switching from a wiping operation to a regeneration operation of the wet cleaning device 1.

Wie in Figur 6 dargestellt, ist der Reinigungswalze 3 hier eine Mehrzahl von Düsen 21 zugeordnet, mit deren Hilfe Flüssigkeit auf den Reinigungsbelag 4 der Reinigungswalze 3 gespritzt werden kann. Das Auftragen der Flüssigkeit auf die Reinigungswalze 3 erfolgt vorzugsweise direkt während und/oder nach Abschluss eines Regenerationsbetriebs. Die aus den Düsen 21 austretende Flüssigkeit trifft gegen die konkav ausgebildete Fläche des Führungselementes 9 und strömt daran entlang zu dem Reinigungsbelag 4, sodass die Flüssigkeit mittels des Führungselementes 9 bzw. des Abbremselementes 5 zwischen die Fasern 6 geleitet werden kann.As in Figure 6 shown, the cleaning roller 3 is assigned a plurality of nozzles 21, with the help of which liquid can be sprayed onto the cleaning pad 4 of the cleaning roller 3. The liquid is preferably applied to the cleaning roller 3 directly during and / or after completion of a regeneration operation. The liquid emerging from the nozzles 21 strikes the concave surface of the guide element 9 and flows along it to the cleaning pad 4, so that the liquid can be passed between the fibers 6 by means of the guide element 9 or the braking element 5.

Die Figuren 7 und 8 zeigen schließlich eine perspektivische Ansicht der Reinigungswalze 3 und eines die Reinigungswalze 3 umgebenden Gehäuses 18, welches ein feststehendes (in den Figuren oberes) Gehäuseteil aufweist und ein relativ zu dem feststehenden Gehäuseteil bewegliches Gehäuseteil, das für einen Wischbetrieb in Umfangsrichtung der Reinigungswalze 3 verschoben werden kann, sodass die Reinigungswalze 3 auf eine zu reinigende Fläche abgesenkt werden kann. Während des Regenerationsbetriebs bilden die beiden Gehäuseteile hingegen ein in Umfangsrichtung vollständig geschlossenes Gehäuse 18, sodass von der Reinigungswalze 3 abgeschleuderte Flüssigkeit nicht nach außerhalb des Feuchtreinigungsgerätes 1 gelangen kann.The Figures 7 and 8th finally show a perspective view of the cleaning roller 3 and a housing 18 surrounding the cleaning roller 3, which has a fixed (upper in the figures) housing part and a housing part which is movable relative to the fixed housing part and which can be displaced in the circumferential direction of the cleaning roller 3 for wiping operation , so that the cleaning roller 3 can be lowered onto a surface to be cleaned. During the regeneration operation, however, the two housing parts form a housing 18 which is completely closed in the circumferential direction, so that liquid thrown off by the cleaning roller 3 cannot get outside of the wet cleaning device 1.

Figur 7 zeigt einen Zustand, bei welchem das Abbremselement 5 zwischen die Fasern 6 des Reinigungsbelages 4 geschoben ist, sodass Flüssigkeit bzw. Schmutz wie zuvor erläutert von den Fasern 6 zu dem Flüssigkeitskanal 10 gelangen kann. Figure 7 shows a state in which the braking element 5 is pushed between the fibers 6 of the cleaning pad 4, so that liquid or dirt can reach the liquid channel 10 from the fibers 6 as previously explained.

Figur 8 zeigt einen von der Reinigungswalze 3 weg geschwenkten Zustand des Abbremselementes 5 und des Führungselementes 9, wobei das Führungselement 9 so vor dem Flüssigkeitskanal 10 angeordnet ist, dass der Flüssigkeitskanal 10 fluiddicht verschlossen ist und Schmutz bzw. Flüssigkeit nicht aus dem Flüssigkeitskanal 10 zurück zu der Reinigungswalze 3 gelangen kann. Figure 8 shows a state of the braking element 5 and the guide element 9 pivoted away from the cleaning roller 3, the guide element 9 being arranged in front of the liquid channel 10 in such a way that the liquid channel 10 is closed in a fluid-tight manner and dirt or liquid is not returned from the liquid channel 10 back to the cleaning roller 3 can reach.
