Definitions

  • the invention relates to a wet cleaning device with a cleaning roller which is mounted such that it can rotate about a roller axis and a roller cover which at least partially surrounds the cleaning roller in the circumferential direction.
  • the invention relates to a device for regenerating a cleaning roller of a damp cleaning device, namely an independent base station designed separately from the damp cleaning device for receiving a partial area of a damp cleaning device that has 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 made up 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, wherein the cleaning roller is surrounded by a roller cover at least in the circumferential direction for regeneration operation and is rotated about a roller axis, liquid being thrown from the cleaning roller onto an inner wall of the roller cover.
  • the DE 102 29 611 B3 discloses, for example, a wet cleaning device with a wiping body that can be driven in rotation 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, with the wiping body picking up dirt from the surface to be cleaned.
  • the wiping body is increasingly covered with dirt, so that regeneration becomes necessary.
  • the wiper body is lifted off the surface to be cleaned, surrounded by a housing and sprayed with unused cleaning fluid.
  • the wiping body rotates so that cleaning liquid and dirt are expelled from the wiping body, hit the inside of the housing and are transferred to a collection container for dirty liquid.
  • the roller cover has, at least on a partial area of an inner wall of the roller cover, a partial section of a flow guidance structure that winds helically in the axial direction, the flow guidance structure having a helical shape with a plurality of turns that merge into one another and thus liquid within the flow guidance structure to a liquid discharge port on an end side of the roller cover can convey, follows, with liquid thrown off the cleaning roller flowing through the windings one after the other, with the flow guidance structure on the inner wall of the roller cover being designed in such a way that the partial section of the flow guidance structure with a corresponding flow structure of a second roller cover of an independent base station designed separately from the wet cleaning device or with other partial areas of the inner wall of the same roll cover can be supplemented to form the helical shape.
  • the roller cover now has a flow guidance structure on the inside, which guides the liquid within the roller cover in a targeted manner.
  • the flow guidance structure follows a helical shape with a plurality of turns that merge into one another and can thus convey liquid within the flow guidance structure.
  • the liquid discharged from the cleaning roller now receives an impulse in a conveying direction when it hits the windings, which 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 cleaning roller can be regenerated more quickly overall and with better regeneration results.
  • the flow guide structure Since the flow guide structure is wound helically around the roll axis, the directional transport of the liquid occurs parallel to the roll axis.
  • the pitch of the helically winding flow guide structure is advantageously constant in a direction parallel to the roll axis.
  • the flow guide structure on the inner wall of the roller cover is also designed in such a way that the partial section of the flow guide structure can complement a corresponding flow structure of a second roller cover, which is provided by a base station for the wet cleaning device, to form the helical shape.
  • the roller cover, which completely surrounds the cleaning roller in the circumferential direction is composed of several parts, each of which provides parts of the windings of the flow guidance structure.
  • the wet cleaning device it is also possible for the wet cleaning device to provide the entire roller cover, for example in the form of two half-cylinders that can be displaced relative to one another.
  • wet cleaning device is to be understood as meaning devices which exclusively or inter alia also allow wet cleaning. These include, on the one hand, the hand-held and automatically movable wet cleaning devices, in particular cleaning robots, and on the other hand, combined dry and wet cleaning devices, which can also carry out dry cleaning in addition to wet cleaning.
  • wet cleaning devices for cleaning above-floor surfaces 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 covering, the cleaning covering having a microfiber in particular.
  • the regeneration operation of the wet cleaning device for regenerating the cleaning roller can preferably be carried out 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 the degree of soiling of the cleaning roller and, depending on this, initiate a regeneration operation if necessary. If the regeneration operation is carried out entirely only in the wet cleaning device itself, the amount of liquid available is limited in order not to excessively increase the size of the wet cleaning device.
  • the cleaning roller arranged in the wet cleaning device is carried out using an external device, preferably a base station for the wet cleaning device, the size of the external device is less relevant and the stored volume of liquid can be larger.
  • the wet cleaning device can preferably also be moved into the device with a partial area and/or placed on a partial area of the device, so that the cleaning roller can be housed in combination with 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 selectively closing and/or releasing an opening area of the roller cover, with an inner wall of the cover element having a partial section of the flow guidance 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 arranged stationary on a housing of the wet cleaning device and a further roller cover part is a movable cover element which can be displaced relative to the stationary roller cover part.
  • the roller cover can thus be closed or released as desired by shifting the cover element in the circumferential direction on the one hand to allow the cleaning roller to be placed on a surface to be cleaned during a wiping operation and on the other hand to achieve a complete housing of the cleaning roller in the circumferential direction by means of the roller cover for a regeneration operation.
  • the cover element is preferably displaced by pivoting. Alternatively, however, a linear displacement, for example along a rail or the like, is also possible. All of the roller cover parts and thus also the displaceable cover element form with their partial cutouts a common flow guidance structure for guiding the liquid discharged from the cleaning roller on the inner wall of the roller cover.
  • the wet cleaning device can carry out the regeneration operation without the aid of a base station or other device for regeneration.
  • the wet cleaning device itself has its own device for regenerating the cleaning roller, possibly including additional components such as a liquid application device for moistening the cleaning roller, in particular liquid nozzles, dirty water channel, dirty water tank and the like.
  • At least a partial area of a peripheral surface of the cleaning roller is in mechanical contact with the flow guidance structure.
  • the cleaning roller rubs completely or with at least a partial area of its peripheral surface on the inner wall of the roller cover.
  • the peripheral surface of the cleaning roller ie the cleaning covering of the cleaning roller, is compressed and relieved again by the windings of the flow guidance structure.
  • This additional action on the peripheral surface, the cleaning roller with a opposite be regenerated with less liquid than the prior art.
  • the total consumption of liquid during the regeneration operation can be as little as 25 ml, for example.
  • the peripheral surface of the cleaning roller is in mechanical contact with the flow guidance structure, it is advisable to have an outer diameter of the cleaning roller or of the cleaning coating which is larger than the inner diameter of the roller cover, so that the flow guidance structure can engage, for example, with the fibers of the cleaning roller.
  • the roller cover has a liquid outlet opening at the end in relation to an axial direction, which opening can in particular have a flow connection to a liquid tank. Since the flow guidance structure conveys the liquid 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 into a liquid tank, in particular a dirty liquid tank. Starting from the roller cover, the liquid thus reaches a liquid tank directly, so that a user of the wet cleaning device does not have to come into contact with the liquid. In addition, leakage of liquid onto the freshly cleaned surface is 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 that can convey the liquid spun 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 guidance structure, which depends on the direction of rotation of the cleaning roller. If the cleaning roller rotates in opposite directions during the regeneration operation (or possibly also during the wiping operation). can be rotated, liquid outlet holes on both end sides of the roller cover are recommended.
  • a displaceable adjusting element is arranged, which can be moved from an open position releasing a winding for the continuous flow into a subsequent winding into a separating position preventing the continuous flow, the adjusting element being rotatable and/or or pivotable.
  • the proposed adjusting element can switch over a flow path of the liquid within the flow guidance structure in the manner of a shunt.
  • the continuous, helically wound flow guide structure can be either interrupted or released. For example, liquid flowing within a turn can be guided such that it remains, for example, within the same turn without advancing in the axial direction.
  • the actuating element In a first position, the open position, the actuating element is preferably aligned parallel to the direction of flow of the liquid within the respective winding, so that the liquid can flow unhindered along the flow guidance structure following the course of the winding. In a second position, the disconnected position, the actuating element is shifted into the flow path of the liquid, so that the liquid can no longer follow the helical shape in the axial direction, but rather is guided back into the previous turn and thus essentially in a ring shape between two adjacent ones turns. It is also possible that the actuating element in an open position enables a flow of the liquid in an axially advancing direction, but switches a flow path in which a turn is skipped. This accelerates the evacuation of the liquid within the roller cover.
  • the flow guidance structure makes sense for the flow guidance structure to have a large number of adjusting elements, which are arranged in adjacent turns.
  • the adjusting elements can be designed in the manner of a pivotable flap or, for example, can be arranged on a rotatable rotary element.
  • two or more adjusting elements can be arranged on the same rotary element in order to achieve a desired switching position between the windings.
  • the actuating element can be displaced by means of an actuator, with the flow guidance structure having in particular a plurality of actuating elements which can be displaced simultaneously by means of a common actuator.
  • This configuration allows several or all of the actuating elements to be displaced simultaneously by a common actuator via a mechanical coupling.
  • the actuator can in particular be an electric motor, which can act on all adjusting elements or rotary elements via a mechanism.
  • the more adjusting elements are used within the flow guidance structure, the more uniformly the presence or the speed of the liquid can be adjusted over the axial length of the roller cover.
  • the regeneration success of the cleaning roller is thus particularly homogeneous over the longitudinal extent of the cleaning roller.
  • the shifting of all actuating elements into the disconnected position advantageously triggers an intensive washing process of the cleaning roller 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 peripheral surface of the cleaning roller.
  • the liquid can only be transferred to the following winding and continue to follow the helical flow guidance structure when the adjusting elements are moved back into the open position.
  • additional liquid can also be filled into the roller housing, for example be discharged onto the cleaning roller with the aid of spray nozzles, so that the circumferential surface of the cleaning roller is moved through the liquid standing at a lowest point in the roller cover, as in a washing machine.
  • a width of a turn of the flow guidance structure can be changed.
  • the flow guidance structure can in particular be formed at least partially from a flexible material and/or be adjustable with respect to the width of the winding by means of an actuator.
  • the width of the coil By increasing or decreasing the width of the coil, the spacing between adjacent coils can be increased or decreased, resulting in a change in the pitch of the helical shape of the flow guide structure. This affects the velocity of the liquid within the flow guide structure.
  • the reduction or enlargement of the flow path within the coil leads to an increase or decrease in the local flow velocity.
  • the inner wall of the roller cover or the roller cover as a whole can be made 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 become.
  • the flow guidance structure can also be designed in the manner of a bellows. A sliding mechanism acting on the flow guidance structure can either only be assigned to a specific winding or also to a number of windings.
  • a device for regenerating a cleaning roller of a wet cleaning device is also proposed, which device is separate from the wet cleaning device is a trained, independent base station for receiving a partial area of a wet cleaning device that has a cleaning roller. It is proposed that this device has 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 winding helically in the axial direction at least on a partial area of an inner wall of the roller cover.
  • the proposed device is a device designed separately from the wet cleaning device, namely an independent base station designed separately from the wet cleaning device, into which a wet cleaning device can be inserted at least with a partial area.
  • the proposed device has a roller cover which only partially surrounds the cleaning roller in the circumferential direction. At least on a partial area of its inner wall, this roller cover has a partial section of a flow guide structure previously proposed with regard to the wet cleaning device. Since the device is a base station, into which a section of the wet cleaning device including the cleaning roller and the roller cover of the wet cleaning device is inserted, the roller cover is composed of the roller cover of the wet cleaning device and the roller cover of the regeneration device, namely the base station, in the circumferential direction .
  • the windings of the flow guidance structure are thus provided partly (in particular an angular range) by the wet cleaning device and partly by the regeneration device. Overall, the cleaning roller is completely enclosed in the circumferential direction.
  • a system consisting of a device, in particular the device described above, and a wet cleaning device of the type mentioned above, with the roller covers of the device and the wet cleaning device corresponding to one another in terms of their shape in such a way that the cleaning roller can be completely surrounded by the roller covers in the circumferential direction and the partial sections of the flow guidance structure on both sides complement each other to form a continuous helically winding overall structure.
  • the wet cleaning device can have all the features explained above, particularly preferably mechanical contact between the peripheral surface of the cleaning roller and the flow guidance structure, a roller cover with liquid outlet openings, adjusting elements and the like. The advantages of the system arise as explained above in relation to the regeneration device or the wet cleaning device.
  • the invention also proposes a method for regenerating a cleaning roller of a wet cleaning device, wherein the cleaning roller is surrounded by a roller cover at least in the circumferential direction for regeneration operation and is rotated about a roller axis, liquid being thrown from the cleaning roller onto an inner wall of the roller cover and there along a helically winding flow guide structure in the axial direction and towards a liquid outlet opening of the roll cover, the flow guide structure following a helical shape with merging turns, the turns conveying liquid within the flow guide structure to the liquid outlet opening at one end face of the roll cover, and wherein from the Liquid thrown off by the cleaning roller flows through the windings one after the other.
  • the liquid thrown off the peripheral surface of the cleaning roller and/or possibly also additionally sprayed liquid onto the surface of the cleaning roller is conveyed to the inner wall of the roller cover by means of the flow guide structure, depending on the direction of rotation of the cleaning roller out and thus promoted specifically within the roll cover, namely in the axial direction, which is defined by the helical helix.
  • the flow guidance structure can additionally serve to act mechanically on the cleaning roller when it comes into contact with the peripheral surface of the cleaning roller, in that the peripheral surface is cyclically compressed and relieved when the cleaning roller rotates.
  • the dwell time of the liquid in individual turns of the flow guidance structure can be influenced by displaceable adjusting elements which force the liquid within the flow guidance structure into specific orbits, for example on a recurring annular path of a turn or by skipping a turn by means of an adjusting element.
  • the gradient of the flow guidance structure be changed with the aid of flexible windings. As already explained above, this can be achieved, for example, by widening or compressing one or more windings.
  • 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 that liquid is additionally introduced into the volume surrounded by the roller cover until the cleaning roller dips into the liquid with a circumferential section that is the deepest in relation to a vertical direction, in particular with an immersion depth of approx. 1mm to 10mm.
  • the cleaning roller thus rotates through the liquid inside the roller cover, which is partially filled with liquid, as is usual, for example, in a washing machine.
  • the cleaning roller can also be sprayed with liquid.
  • 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 possibly increasing the dwell time of the cleaning roller in a specific rotational position.
  • a particularly effective regeneration process for the cleaning roller is thus created.
