Definitions

  • the invention relates to a cleaning device, in particular a floor cleaning device, with a rotatably mounted cleaning roller for cleaning a surface, which cleaning roller is assigned a Walzenmitauer for rotational cooperation with a device side driven shaft, which Walzenmit supplements is at least partially inserted into an axial roller recess of the cleaning roller, and wherein the Walzenmitauer and the roller recess can be brought into cooperation engageable coupling means.
  • Cleaning devices of the aforementioned type are known. These have one or more cleaning rollers, which are usually acted upon with liquid and are used for damp mopping a surface to be cleaned.
  • the cleaning roller is rotatably mounted within the cleaning device.
  • the publication WO 1997/045052 A1 discloses, for example, a cleaning device with a tubular brush body, in which a shaft of the cleaning device can be inserted.
  • the non-rotatable coupling of the brush body on the shaft via a rotationally fixed content Erten on the shaft driver, which cooperates with radially inwardly projecting driving projections of the brush body.
  • the corresponding projections are designed for a torque transmission so that these together in the circumferential direction as possible without play lie. This results in a relatively high production cost and the risk of tilting of the projections when connecting the cleaning roller to the shaft.
  • the Walzenmit screening has a Walzenmit paradefeder by which the coupling means in an assembled state for transmitting torque against each other are securable.
  • the torque-transmitting coupling between the Walzenmit Vietnamese and the cleaning roller is no longer (at least not exclusively) via an engagement of the coupling means in the circumferential direction. Rather, the Walzenmit choir a Walzenmit leisurefeder is assigned, the restoring force presses the coupling means of the Walzenmit supplementss in the axial direction of the cleaning roller against the coupling agent of the cleaning roller, or vice versa. As a result, the torque transmission takes place essentially by the Walzenmit FIFAfeder.
  • the interconnected coupling means serve as abutment surfaces against which the restoring force of the Walzenmit repertoire acts.
  • the Walzenmit recruitingfeder is coaxially arranged on the Walzenmit hormonal coil spring.
  • the Walzenmit livelyfeder is pushed over the Walzenmit supplement, so that the turns of the Walzenmit increasingly rest against the outer surface of the Walzenmit demandss.
  • the inner diameter of the Walzenmit recruitingfeder corresponds to the outer diameter of the Walzenmit facilities, automatically results in a centering of Walzenmit increasingly to the Walzenmit alone and within the roll recess of the cleaning roller, so that the restoring force of Walzenmit increasingly is distributed in the circumferential direction of the Walzenmit ceremonies substantially equal and thus - depending on the geometric shape of the coupling agent - can act evenly against the coupling agent in the circumferential direction.
  • the torque can optionally be transmitted over the entire circumference of the Walzenmit disorders on the cleaning roller. This is particularly true when both the coupling means of Walzenmit Vietnameses and the coupling means of the cleaning roller are annular with respect to a radial cross-section.
  • a coupling means of the cleaning roller is arranged in the assembled state relative to an axial direction of the cleaning roller between a coupling means of the Walzenmit disorders and the Walzenmit leisurefeder.
  • the Walzenmit FIFAfeder acts from the coupling means of Walzenmit disorders opposite side against the coupling agent of the cleaning roller, so that the tensioned Walzenmit increasinglyfeder acts on the one hand to transmit torque against the corresponding coupling means, and on the other presses the Walzenmitauer against a coupling device of the device side driven shaft and thus allowing the rotation of the cleaning roller.
  • This training also allows a particularly convenient assembly and disassembly of the cleaning roller inside the cleaning device.
  • the roller driver For mounting the cleaning roller, the roller driver is inserted into the roller recess until the coupling means of the roller carrier engages behind the coupling means of the cleaning roller in the axial direction of the cleaning roller.
  • the Walzenmit supportivefeder is tensioned so that the axial total length of the cleaning roller including Walzenmit supplements reduced and a comfortable assembly for torque-transmitting coupling of the cleaning roller with the shaft is possible.
  • the user grasps the cleaning roller and displaces it against the restoring force of the roller driving spring.
  • the Walzenmit vide pushes further into the cleaning roller until the coupling means of the Walzenmit ceremoniess by a certain amount of the coupling means of Cleaning roller is spaced. In this position, the total length of cleaning roller and Walzenmit diversity is reduced so that the cleaning roller can be removed from the cleaning device.
  • the coupling agents can be brought together in the manner of a latching connection. This allows the previously described, in particular captive, coupling of the coupling agent.
  • the coupling agent of the cleaning roller is annular.
  • the coupling means of the roller follower slides over the coupling means of the cleaning roller until the coupling means of the roller follower snaps behind the coupling means of the cleaning roller.
  • the coupling means of Walzenmit followss this elastic material properties and the shape of a hook.
  • a coupling device of the device-side driven shaft and the Walzenmit supplements have corresponding coupling elements for torque-transmitting connection, wherein a coupling element of the Walzenmit supplementss is formed on the end remote from a coupling means of Walzenmit disorders end of the Walzenmit demandss.
  • the Walzenmit disruptive is thus separable from the coupling device or the device-side driven shaft, so that a particularly simple removal of the Walzenmit disorders or the cleaning roller from the cleaning device is possible.
  • To remove the Walzenmitauer is axially displaced into the cleaning roller, so that in addition to the cleaning roller creates a free space, which allows a convenient removal of the cleaning roller including Walzenmit diversity.
  • the corresponding ones Coupling elements may be formed according to the type of projections projecting in the axial direction of the roller driver, which projections can mesh with one another in a corresponding shape and thus effect the transmission of torque.
  • a cleaning device 1 in the form of a wet cleaning device for the wet cleaning of a surface to be cleaned.
  • the cleaning device 1 has an attachment 13, which is in a cleaning operation in contact with the surface to be cleaned.
  • the attachment 13 in this case has, for example, two cleaning rollers 2, which can be acted upon with liquid, such as water.
  • the cleaning rollers 2 can be sprayed, for example, with the liquid or coated with a moist roll coating 15.
  • the cleaning device 1 is supported by the two cleaning rollers 2 on the surface to be cleaned.
  • the cleaning rollers 2 extend transversely to a usual direction of travel r of the cleaning device 1, which results from a normal working movement of a user of the cleaning device 1, namely generally alternately back and forth, this possibly further while evading into a nearest, parallel cleaning track.
  • the cleaning rollers 2 extend here approximately over the entire transverse to the direction of travel r width of the cleaning device 1.
  • a cleaning roller 2 at a movement of the cleaning device 1 in the direction of travel r front or rear of the attachment 13 is arranged.
  • the cleaning rollers 2 are driven by an electric motor, that is rotatable about a rotation axis. During a conventional movement of the cleaning device 1, without processing a surface to be cleaned, the cleaning rollers 2 are advantageously not actively driven.
  • a passive rotation of the cleaning rollers 2 then results solely from the frictional engagement with the surface to be cleaned.
  • they are actively rotated by means of the electric motor.
  • a wiping edge is established along the contact line between the cleaning roller 2 and the surface to be cleaned. This wiper edge makes it possible to clean the surface by moving it relative to the surface, which dissolves dirt.
  • FIG. 2 shows a cleaning roller 2, which is connected to a Walzenmit legislative 3, which serves for transmitting a torque from a shaft (not shown) of the electric motor to the cleaning roller 2.
  • the Walzenmit clergy 3 is connected to a coupling device 4, which in turn via a toothed belt 14 with the shaft of the electric motor is coupled.
  • a bearing 5 is arranged, which serves together with the coupling device 4 for holding the cleaning roller 2 in the cleaning device 1.
  • the Walzenmitmony 3 is inserted into the cleaning roller 2.
  • FIG. 3 shows the cleaning roller 2, the Walzenmitauer 3, the coupling device 4 and the bearing 5 in a longitudinal section.
  • the Walzenmit comedy 3 has at its free end to a backdrop of a plurality of coupling means 8, which are arranged in the circumferential direction of the Walzenmit supplementss 3 side by side and spaced by free spaces 10 from each other.
  • the coupling means 8 are hook-shaped and have radially outwards, ie in the direction of the Walzenmitauer 3 coaxially surrounding cleaning roller 2.
  • the cleaning roller 2 has a Walzenmitauer 3 receiving roller recess 6, which is at least partially formed in the axial direction within the cleaning roller 2.
  • the roller recess 6 has an annular, radially inward, ie in the direction of Walzenmit disorders 3, facing coupling means 7.
  • the coupling means 8 of the Walzenmit disorders 3 engage behind the coupling means 7 of the cleaning roller 2, so that the Walzenmitauer 3 is captively connected to the cleaning roller 2.
  • the Walzenmitauer 3 carries on its peripheral surface a Walzenmitauerfeder 9, which is designed here as a helical spring.
  • the Walzenmit comedyfeder 9 is form-fitting to the Walzenmitterrorism 3, so that a coaxial centering is given.
  • the coupling elements 11, 12 are as formcorresponding Formed projections, so that a torque can be transmitted from the coupling device 4 on the Walzenmit Vietnamese 3.
  • the coupling device 4 is connected by means of the toothed belt 14 with the electric motor of the cleaning device 1, so that upon rotation of the shaft of the electric motor also the coupling device 4 and thus also the associated Walzenmit parade 3 rotates.
  • the cleaning roller 2 is connected to a bearing 5, which is designed here for example as a ball bearing and thus enables the rotation of the cleaning roller 2.
  • a roller covering 15 is arranged, which may be formed as a sponge body and / or cleaning cloth or the like.
  • FIG. 4 shows the coupling device 4, which serves for the torque-transmitting connection with the Walzenmit Vietnamese 3.
  • the coupling device 4 shown is only an example. In principle, other types of coupling devices 4 may be provided, which allow a torque transfer and are also suitable as a bearing for the Walzenmit repertoire 3 in the cleaning device.
  • FIGS. 5 and 6 show two different views of Walzenmit interventions 3rd
  • FIG. 5 shows in particular the four coupling means 8, which are arranged in a cross section of the Walzenmit ceremonies 3 substantially on a circular path.
  • FIG. 6 shows, in particular, the end portion of the roller cam 3 facing away from the link, on which the coupling elements 12 are arranged for torque-transmitting connection with the coupling elements 11 of the coupling device 4.
  • the invention now works so that a user of the cleaning device 1 for installation of a cleaning roller 2 in the cleaning device 1, the Walzenmit supplements 3 in the roller recess 6 of the cleaning roller 2 introduces.
  • the Walzenmit supportivefeder 9 surrounding the Walzenmit clergy 3 is tensioned, so that the restoring force increases as the axial movement of the Walzenmit disorders 3 progresses.
  • the axial displacement is continued until the coupling means 8 of the Walzenmit supplementss 3 slide over the coupling means 7 of the cleaning roller 2 and finally lock behind it.
  • the coupling means 8 of the Walzenmit ceremonies 3 an arrow-shaped edge to facilitate the overcoming of the coupling means 7 of the cleaning roller 2.
  • the coupling means 7 of the cleaning roller 2 is in the axial direction of the cleaning roller 2 between the Walzenmit supportivefeder 9 and the corresponding coupling means 8 of the Walzenmit demandss 3.
  • the Walzenmitauerfeder 9 presses with its restoring force against the coupling means 7 of the cleaning roller 2 and at the opposite end of Walzenmit interventionss 3 in the direction of the coupling device 4, so that the coupling elements 11, 12 are ready for torque transmission.
  • the cleaning roller 2 can now be rotated by means of the shaft of the electric motor.
  • the user of the cleaning device 1 takes the cleaning roller 2 and moves it axially in the direction of the coupling device 4, so that the Walzenmit autismfeder 9 is further compressed and the Walzenmit hormonal 3 deeper moved into the roller recess 6 of the cleaning roller 2.
  • the coupling means 8 of the Walzenmit parentss 3 is spaced from the coupling means 7 of the cleaning roller 2, so that the total length of cleaning roller 2 and Walzenmit protagonist 3 is reduced and the cleaning roller 2 together with the Walzenmit skills 3 can be removed from the cleaning device 1. This is done in the direction of the restoring force of Walzenmit repertoire 9.
