Definitions

  • the invention relates to a wet cleaning device, in particular a wet wiping device, with a cleaning roller which can be rotated about a roller axis and which has a cleaning coating, the wet cleaning device (1) comprising a braking element and a guide element for supporting the removal and removal of liquid and / or dirt from the cleaning roller has a liquid channel, the braking element having an impact edge opposite the fibers of the rotating cleaning pad.
  • the invention relates to a method for operating a wet cleaning device, in particular a wet wiping device, in which liquid and / or dirt are removed from a cleaning coating of a cleaning roller of the wet cleaning device rotating about a roller axis during a regeneration operation.
  • the DE 10129 611 B3 discloses a wet cleaning device with a wiper body which can be driven to rotate about an axis of rotation, in which a cleaning liquid is removed from a storage tank and sprayed onto the wiping means by means of spray nozzles arranged in the direction of the axis of rotation of the wiper body Surface of the wiper body is sprayed.
  • 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.
  • US 1,536,687 A. . US 5 657 504 A and US 2007 / 011838A1 also disclose wet cleaning devices with a rotating roller.
  • a wet cleaning device 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.
  • 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 guide element is thus preferably an end region of a channel wall which, as previously proposed, has an arc shape.
  • 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.
  • a swivel arm can be provided accordingly.
  • the displacement 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.
  • 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.
  • 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.
  • 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 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.
  • the cleaning roller 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.
  • 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 °.
  • an angle greater than 105 ° leads to a relevant reduction in the fanned-out width of the liquid jet.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • wet cleaning devices are to be understood as all those devices which can exclusively or, among other things, carry out wet cleaning.
  • 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.

  • 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.
  • 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.
  • 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.
  • the Figures 2 to 4 each show the cleaning roller 3 with the cleaning covering 4, which has a multiplicity of fibers 6.

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.

  • 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.
