Definitions

  • the invention relates to a wet cleaning device with a cleaning roller rotatably mounted about a roller axis and a roller cover at least partially surrounding the cleaning roller in the circumferential direction.
  • the invention also relates to a device for regenerating a cleaning roller of a damp cleaning device, in particular a base station for receiving a partial area of a damp cleaning device having a cleaning roller, the device having a roller cover for at least partially surrounding the cleaning roller in the circumferential direction.
  • the invention also relates to a system consisting of such a device and such a wet cleaning device.
  • the invention also relates to a method for regenerating a cleaning roller of a damp cleaning device, the cleaning roller being surrounded at least in the circumferential direction with a roller cover for a regeneration operation and being rotated around a roller axis, with liquid being thrown from the cleaning roller onto an inner wall of the roller cover.
  • Damp cleaning devices of the aforementioned type are known in the prior art.
  • the DE 102 29 611 B3 discloses, for example, a wet cleaning device with a wiping body which can be driven to rotate about an axis of rotation, in which a cleaning liquid is taken from a storage tank and sprayed onto the surface of the wiping body by means of spray nozzles arranged in the direction of the axis of rotation of the wiping body.
  • the wiping body moistened in this way is guided over a surface to be cleaned during a wiping operation, the wiping body picking up dirt from the surface to be cleaned.
  • the wiping body is increasingly covered with dirt, so that regeneration is necessary.
  • the wiping body is lifted from the surface to be cleaned, surrounded by a housing and sprayed with unused cleaning fluid.
  • the wiper body rotates so that cleaning liquid and dirt are expelled from the wiper body, hit the inside of the housing and are transferred to a collecting container for dirty liquid.
  • the object of the invention is to further develop a damp cleaning device in such a way that the transport of liquid within the roller cover is improved, in particular also with regard to faster drainage of the liquid.
  • the roller cover at least on a partial area of an inner wall of the Roller cover has a partial section of a flow guide structure which winds helically in the axial direction.
  • the roller cover now has a flow guide structure on the inside, which guides the liquid in a targeted manner within the roller cover.
  • the flow guide structure follows a helical shape with a plurality of turns, which merge into one another and can thus convey liquid within the flow guide structure.
  • the liquid discharged by the cleaning roller now receives an impulse in a conveying direction when it hits the windings, which impulse corresponds to the course of the windings in the axial direction of the roller cover.
  • the liquid can thus be drained off in a more directed and faster manner than in the prior art, so that the regeneration of the cleaning roller can take place overall faster and with a better regeneration result.
  • the flow guide structure Since the flow guide structure is wound helically around the roller axis, the directional transport of the liquid takes place parallel to the roller axis.
  • the slope of the helically winding flow guide structure is advantageously constant in a direction parallel to the roller axis.
  • the flow guide structure on the inner wall of the roller cover is also designed so that the partial section of the flow guide structure is formed with a corresponding Flow structure of a second roller cover, which is provided for example by a base station for the wet cleaning device, can supplement the screw shape.
  • the roller cover completely surrounding the cleaning roller in the circumferential direction is composed of a plurality of parts which each provide parts of the turns of the flow guide structure.
  • the damp-cleaning device it is also possible for the damp-cleaning device to provide the entire roller cover, for example in the form of two semi-cylinders that can be displaced relative to one another.
  • wet cleaning device is to be understood as meaning devices which exclusively or among other things also enable wet cleaning. These include, on the one hand, hand-held and automatically movable damp cleaning devices, in particular cleaning robots, and, on the other hand, combined dry and damp cleaning devices which can also perform dry cleaning in addition to damp cleaning.
  • wet cleaning devices for cleaning above-floor surfaces are also meant. These include, for example, devices for cleaning windows, cleaning shelves, steps, baseboards, edges and the like.
  • the cleaning roller can be a roller surrounded by a cleaning lining, the cleaning lining in particular having a microfiber.
  • the regeneration operation of the wet cleaning device for regenerating the cleaning roller can preferably take place autonomously, so that no additional work is caused for the user of the wet cleaning device.
  • a sensor system of the wet cleaning device can preferably detect a degree of soiling of the cleaning roller and, depending on this, initiate a regeneration operation if necessary. If the regeneration operation is carried out completely only in the wet cleaning device itself, the amount of available liquid is limited in order not to increase the size of the wet cleaning device excessively.
  • the size of the external device is less relevant and the stored liquid volume can be larger.
  • the damp cleaning device can preferably also be retracted with a partial area into the device and / or placed on a partial area of the device, so that the cleaning roller can be housed in a combination of a roller cover of the device and the roller cover of the damp cleaning device.
  • the roller cover of the wet cleaning device has a displaceable cover element for optionally closing and / or exposing an opening area of the roller cover, an inner wall of the cover element having a partial section of the flow guide structure.
  • the roller cover of the wet cleaning device consists of two or more roller cover parts, of which a first roller cover part can be fixedly arranged on a housing of the wet cleaning device and a further roller cover part is a displaceable cover element which can be displaced relative to the fixed roller cover part.
  • the roller cover can thus be closed or released by moving the cover element either in the circumferential direction, on the one hand to enable the cleaning roller to be placed on a surface to be cleaned during a wiping operation and on the other hand to enclose the cleaning roller completely in the circumferential direction by means of the roller cover for a regeneration operation to reach.
  • the cover element is preferably moved by pivoting. Alternatively, however, a linear displacement, for example along a rail or the like, is also possible. All roller cover parts and thus also the displaceable cover element with their partial cutouts form a common flow guide structure for guiding the liquid discharged from the cleaning roller on the inner wall of the roller cover.
  • the damp cleaning device can carry out the regeneration operation without the aid of a base station or other device for regeneration.
  • the damp cleaning device itself has its own device for regenerating the cleaning roller, including possibly further components, such as a liquid application device for moistening the cleaning roller, in particular liquid nozzles, waste water channel, waste water tank and the like.
  • the roller cover preferably has a liquid outlet opening at its end relative to an axial direction, which in particular has a flow connection to a liquid tank. Since the flow guide structure conveys the liquid located inside the roller cover parallel to the roller axis, the conveyance also takes place in the direction of the liquid outlet opening and can be transferred from there to a liquid tank, in particular a dirty liquid tank. The liquid thus reaches a liquid tank proceeding from the roller cover, so that a user of the wet cleaning device does not have to come into contact with the liquid. In addition, leakage of liquid on the freshly cleaned surface is also avoided.
  • an air inlet opening can be provided on the end faces of the cleaning roller, so that the rotation of the cleaning roller generates an air flow which can support the liquid thrown off by the cleaning roller to the liquid outlet opening of the roller cover.
  • the liquid outlet opening is arranged on that end side of the roller cover which corresponds to the conveying direction of the flow guide structure which is dependent on the direction of rotation of the cleaning roller. If the cleaning roller can be rotated in opposite directions of rotation during the regeneration operation (or possibly also during the wiping operation), liquid outlet openings on both end sides of the roller cover are recommended.
  • a displaceable adjusting element is arranged at least between two turns of the flow guiding structure, which can be displaced from an open position that releases one turn for the continuous flow into a subsequent turn into a disconnected position preventing the continuous flow, the adjusting element in particular being rotatable and / or is pivotable.
  • the proposed adjusting element can switch over a flow path of the liquid within the flow guide structure like a switch.
  • the continuous, helically wound flow guide structure can either be interrupted or released.
  • liquid flowing within a turn can be guided in such a way that it remains within the same turn, for example, without advancing in the axial direction.
  • the adjusting element In a first position, the open position, the adjusting element is preferably aligned parallel to the direction of flow of the liquid within the respective turn, so that the liquid can flow along the flow guide structure unimpeded following the course of the turn.
  • the adjusting element In a second position, the disconnected position, on the other hand, the adjusting element is shifted into the flow path of the liquid, so that the liquid cannot follow the helical shape further in the axial direction, but rather is guided back into the previous turn and thus essentially annular between two adjacent ones Windings flows.
  • the adjusting element in an open position to allow the liquid to flow in an axially advancing direction, but to switch a flow path in which a turn is skipped. This accelerates the removal of the liquid inside the roller cover.
  • the flow guide structure prefferably has a plurality of adjusting elements which are arranged in adjacent turns.
  • the adjusting elements can be pivoted in the manner of a Be formed flap, or be arranged, for example, on a rotatable rotary element.
  • two or more adjusting elements can be arranged on the same rotary element in order to achieve a desired switch position between the turns.
  • the actuating element can be displaced by means of an actuator, the flow guide structure in particular having a plurality of actuating elements which can be displaced simultaneously by means of a common actuator.
  • the actuator can in particular be an electric motor which can act on all adjusting elements or rotating elements via a mechanism. The more adjusting elements are used within the flow guide structure, the more uniformly the presence or the speed of the liquid can be adjusted over the axial length of the roller cover. The success of the regeneration of the cleaning roller is therefore particularly homogeneous over the longitudinal extent of the cleaning roller.
  • an intensive washing process of the cleaning roller is advantageously triggered during the regeneration operation, since the liquid or the respective liquid components remain in the respective winding and interact several times with the same axial section of the circumferential surface of the cleaning roller. Only when the adjusting elements are moved back into the open position can the liquid be transferred into the subsequent turn and continue to follow the helical flow guide structure.
  • additional liquid can also be poured into the roller housing, for example discharged onto the cleaning roller with the aid of spray nozzles, so that the peripheral surface of the cleaning roller is like in a washing machine is moved through the liquid standing in the roller cover at a lowest point.
  • a width of a turn of the flow guide structure can be changed.
  • the flow guide structure can in particular be formed at least partially from a flexible material and / or can be adjusted with regard to the width of the winding by means of an actuator.
  • the width of the turn By increasing or decreasing the width of the turn, the distance between the adjacent turns can be increased or decreased, which leads to a change in the pitch of the helical shape of the flow guide structure. This affects the speed of the liquid within the flow guide structure.
  • the reduction or enlargement of the flow path within the winding leads to an increase or decrease in the local flow velocity.
  • the inner wall of the roller cover or the roller cover can be made entirely of a flexible material, preferably an elastic plastic, and can be pulled apart or pushed together in the area of certain turns by means of a sliding mechanism, for example, so that the turns concerned are stretched or compressed will.
  • the flow guide structure can also be designed in the manner of a bellows. A sliding mechanism engaging the flow guide structure can either be assigned to only one specific turn or also to several turns.
  • a device for regenerating a cleaning roller of a damp cleaning device is also proposed, which device is in particular a base station for receiving a partial area of a cleaning roller Damp cleaning device is. It is proposed that this device have a roller cover for at least partially surrounding the cleaning roller in the circumferential direction, the roller cover having a partial section of a flow guide structure which winds helically in the axial direction at least on a partial area of an inner wall of the roller cover.
  • the proposed device can, for example, be a device designed separately from the wet cleaning device, or alternatively also a device arranged in the wet cleaning device itself.
  • the device is particularly preferably an independent base station into which a damp cleaning device can be introduced, at least with a partial area.
  • the cleaning roller it is also possible for the cleaning roller to be removed from the damp cleaning device and to be fed to the device, in particular to a device which is separate from the damp cleaning device.
  • the proposed device has a roller cover which either only partially or completely surrounds the cleaning roller in the circumferential direction. This roller cover has, at least in a partial area of its inner wall, a partial section of a flow guide structure previously proposed in relation to the wet cleaning device.
  • the roller cover is made up of the roller cover of the wet cleaning device and the roller cover of the regeneration device, in particular the base station, in the circumferential direction, together.
  • the windings of the flow guiding structure are thus provided for one part (in particular an angular range) by the damp cleaning device and another part by the regeneration device. Overall, the cleaning roller is completely enclosed in the circumferential direction.
  • the invention proposes a system comprising a device, in particular the device described above, and a damp cleaning device of the aforementioned type, the roller covers of the device and the damp cleaning device corresponding to one another in terms of their shape in such a way that the cleaning roller is completely removed from the circumferential direction Roller covers can be surrounded and the partial sections of the flow guide structure on both sides complement one another to form a continuous, helically winding overall structure.
  • the wet cleaning device can have all of the features explained above, particularly preferably a mechanical contact between the peripheral surface of the cleaning roller and the flow guide structure, a roller cover with liquid outlet openings, adjusting elements and the like. The advantages of the system result as explained above with regard to the regeneration device or the wet cleaning device.
  • the invention also proposes a method for regenerating a cleaning roller of a damp cleaning device, the cleaning roller being surrounded at least in the circumferential direction with a roller cover for a regeneration operation and being rotated around a roller axis, with liquid being thrown from the cleaning roller onto an inner wall of the roller cover and there flows along a flow guiding structure which winds helically in the axial direction, in particular towards a liquid outlet opening of the roller cover.
  • the liquid thrown off from the circumferential surface of the cleaning roller and / or optionally also additionally sprayed onto the surface of the cleaning roller is guided on the inner wall of the roller cover depending on the direction of rotation of the cleaning roller by means of the flow guide structure and is thus specifically conveyed within the roller cover, namely in the axial direction, which is given by the helical coil.
  • the flow guide structure can additionally when in contact with the circumferential surface of the cleaning roller, serve to act mechanically on the cleaning roller, in that the circumferential surface is cyclically compressed and relieved when the cleaning roller rotates.
  • the residence time of the liquid in individual turns of the flow guiding structure can be influenced by displaceable adjusting elements, which force the liquid within the flow guiding structure into certain orbits, for example onto a recurring ring-shaped path of a winding or by jumping over a winding using an adjusting element.
  • the flow guide structure be changed in terms of its slope with the aid of flexible windings. This can be achieved, for example - as already explained above - by widening or compressing one or more turns.
  • the stretching or compression can be achieved by the mechanical action of an actuator.
  • the cleaning roller is completely surrounded by the roller cover and liquid is additionally introduced into the volume surrounded by the roller cover until the cleaning roller is immersed in the liquid with a circumferential section that is deepest in relation to a vertical direction, in particular with an immersion depth of approx. 1 mm to 10 mm.
  • the cleaning roller thus rotates within the roller cover, which is partly filled with liquid, through the liquid, as is customary, for example, in a washing machine. If necessary, the cleaning roller can also be sprayed with liquid.
  • Dirt and liquid are thrown by the centrifugal force generated during the rotation of the cleaning roller against the inner wall of the roller cover and thus also against the flow guide structure and, depending on the current position of one or more adjusting elements, are preferably held in a certain axial section of the roller cover for a certain period of time.
  • a peripheral portion of the cleaning roller is immersed in the liquid standing in the roller cover, so that the fibers of a cleaning pad are gradually washed out as the cleaning roller rotates.
  • additional amounts of liquid of approx In order to ensure that the fibers or the circumferential section of the cleaning roller are submerged, additional amounts of liquid of approx.
  • the cleaning roller can be rotated at a rotational speed of, for example, 1500 revolutions per minute to 6000 revolutions per minute, in particular 4500 revolutions per minute.
  • a rotational speed for example, 1500 revolutions per minute to 6000 revolutions per minute, in particular 4500 revolutions per minute.
  • significantly lower rotational speeds for example from 300 revolutions per minute to 450 revolutions per minute, may also be possible by increasing the dwell time of the cleaning roller in a specific rotational position. Overall, a particularly effective regeneration process for the cleaning roller is thus created.
