Definitions

  • the invention relates to a cleaning device, in particular a floor cleaning device, with a rotatable around a rotation axis cleaning roller for processing a surface to be cleaned, wherein the cleaning roller is at least partially formed as a liquid-permeable hollow body with an internal liquid space, wherein the hollow body openings for the discharge of liquid from the liquid space having on the surface of the hollow body.
  • Cleaning devices of the aforementioned type are known in the art.
  • the document DE 20 2007 017 026 Ul discloses, for example, a floor cleaning device with a cleaning roller designed as a wiping roller, which is supplied from the inside with cleaning liquid. For this purpose, the cleaning roller on a liquid-permeable sleeve body.
  • This is provided for moistening an externally applied to the cleaning roller cleaning cloth with openings, for example.
  • openings for example.
  • the cleaning cloth and / or a possibly arranged between the sleeve body and the cleaning cloth sponge body is formed absorbent, so that permanently liquid is sucked from the sleeve body through the openings.
  • the liquid is transferred from the cleaning cloth or the sponge body to the surface to be cleaned.
  • the disadvantage here is that from the liquid space of the cleaning roller permanently liquid to the surface of the hollow body, ie, the cleaning cloth and / or the sponge body, is discharged.
  • liquid is dispensed even when the cleaning roller is not currently used for a cleaning process, but, for example, is only transported. It is therefore an object of the invention to provide a cleaning device in which liquid only under certain conditions from the liquid space to the Surface of the hollow body is conveyed, so that it can not come to an undesirable leakage or dripping.
  • the invention proposes that the cleaning roller is designed to block below a force equilibrium between a force acting on the liquid capillary force and centrifugal force minimum speed leakage of liquid from the liquid space, and from reaching the minimum speed, a leakage of liquid release from the liquid space.
  • the cleaning device may initially be designed in the sense of a hand-held, preferably guided over a handle cleaning device. It may also alternatively or additionally be a floor care appliance.
  • the floor care or floor cleaning device can also be designed as a self-propelled device. As such, it may be preprogrammed or by cleaning a surface or space independently by finding a cleaning path. It may also be about a window cleaning device.
  • the device In the case of training as a self-propelled device, the device may have an orientation device, such as in the form of a laser scanner, or cooperate with this. It can also have a control device, in particular a microcomputer for storing and / or executing control programs.
  • the capillary force acts on the liquid in the liquid space on the one hand, and on the other hand - on rotation of the cleaning roll - on a centrifugal force.
  • the capillary force causes the liquid present in the liquid space to rise under certain conditions into the openings of the hollow body formed as capillaries and thus reach the surface of the hollow body. This effect is determined by the surface tension of the liquid and the interfacial tension tion between the liquid and the inner wall of the opening caused. For liquids that wet the surface material, the liquid inside the capillary rises to form a concave interface (meniscus).
  • F K ⁇ ⁇ ⁇ xdx cos (0), where ⁇ is the surface tension of the water, d the diameter of the capillary and ⁇ the contact angle.
  • a centrifugal force upon rotation of the cleaning roller about the axis of rotation, a centrifugal force also acts on the liquid located within the liquid space.
  • the centrifugal force acts radially from the axis of rotation to the outside, i. in the direction of the openings of the hollow body, so that the liquid can escape under certain conditions from the liquid space to the surface.
  • the centrifugal force depends here on the diameter d of the opening, the water level h within the liquid space (during rotation), the density p of the liquid, the rotation speed v and the center of gravity r of the liquid. Assuming that here only the liquid level under the opening is considered, the centrifugal force results
  • the capillary force and the centrifugal force point in the same direction, ie radially outward.
  • the liquid does not wet the material of the hollow body, oppose the capillary force and the centrifugal force, so that based on the balance of forces between the capillary force and the centrifugal force a minimum speed can be calculated, which is required for the centrifugal force exceeds the radially inwardly acting capillary force and thus the liquid can pass from the liquid space to the surface of the hollow body.
  • Diameter of the opening, the contact angle, the center of gravity of the liquid within the liquid space, the liquid level within the liquid space (with rotation of the cleaning roller) and the density of the liquid for each constellation calculate a minimum speed of the cleaning roller, from which an exit of liquid from the liquid space is possible. If this minimum speed is not reached, ie the cleaning roller rotates at a lower speed, the liquid can not get out of the liquid space to the surface of the hollow body. Thus, it can be specifically controlled by the speed setting of the cleaning roller when liquid emerges and when not. During a mere transport of the cleaning device, in which the cleaning roller usually does not rotate, the discharge of liquid can thus be effectively prevented. In contrast, the cleaning roller for a Cleaning operation, which requires the use of liquid, rotates at a speed exceeding the minimum speed, so that the centrifugal force exceeds the capillary force and liquid can be discharged to the surface to be cleaned.
  • a contact angle between the liquid and an inner wall of the opening is greater than 90 ° up to 270 °.
  • the contact angle between the liquid and the inner wall of the opening is decisive for the exit of the liquid from the liquid space. If the contact angle is greater than 90 °, the cosine of the contact angle influencing the capillary force becomes negative. This means that the liquid does not rise in the opening, but rather displaces liquid in the opposite direction, so that the capillary force opposes the centrifugal force.
  • This effect is exploited by the invention in that material combinations for the liquid and the hollow body are selected in a targeted manner, which lead to a contact angle greater than 90 ° up to 270 °.
  • the capillary force acts accordingly against the centrifugal force of the liquid. If the speed of the cleaning roller is large enough so that the centrifugal force exceeds the capillary force, liquid will escape from the liquid space. Overall, the liquid outlet can thus be regulated by the choice of materials, the speed and the diameter of the openings. Consequently, no pump, valves, fliehkraftchene flaps or the like was needed.
  • the liquid is water and the hollow body has a hydrophobic material, in particular polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the PTFE may be a coating of the hollow body, in particular the openings.
  • the hydrophobic property of the hollow body means that the water within the openings has a contact angle greater than 90 °, so that the capillary force is turned in the direction of the liquid space and thus opposes the centrifugal force. Thus, it may come to the previously explained balance of forces between the capillary force and the centrifugal force.
  • hydrophobic materials conceivable, for example wax or paraffin.
  • the hollow body may consist entirely of the hydrophobic material, or at least within the liquid space, in particular the openings, have a coating of this hydrophobic material.
  • the openings have a diameter of 0.5 ⁇ m to 2 mm. This diameter is sufficiently small so that the liquid located within the liquid space can not pass through the openings from the liquid space due to the gravitational force alone.
  • openings with such a diameter have a sufficiently strong capillary effect, i. a sufficient rise height of the liquid within the opening, in order to enable the operation according to the invention.
  • the openings may advantageously be capillaries which have been drilled in the material of the hollow body.
  • hollow bodies which consist of a capillary-containing material are also suitable. In the latter case, however, in the context of the invention, it is a prerequisite that the diameters of the openings are approximately equal or each have a clearly defined minimum size, so that a common minimum speed for the discharge of liquid from the liquid space can be determined.
  • the hollow body has openings of different diameter with different diameter, wherein an opening with a first diameter is associated with a first minimum speed, and wherein an opening with a second diameter is associated with a second minimum speed.
  • two rotational speeds of the cleaning roller can be defined, from which the respective openings are released for a discharge of liquid.
  • openings with a second, larger diameter first even when reaching the first minimum speed, locked, and are released only upon reaching the second minimum speed for leakage of liquid.
  • two or more groups of openings of different diameters are possible, which are speed-dependent allow only a certain moisture penetration of the cleaning roller and only at increased speed increased release water.
  • the cleaning device is a dry cleaning device, wherein the cleaning roller is formed to block a discharge of liquid from the liquid space of the hollow body at a first speed corresponding to a surface treatment by means of the cleaning roller and at a second, higher speed corresponding to a self-cleaning of the cleaning roller to release a leakage of liquid from the liquid space.
  • the invention is thus in no way limited to wet cleaning appliances. Rather, the invention can also be used particularly advantageously in dry cleaning appliances.
  • the cleaning device is designed so that the speed used for a conventional processing of the surface to be cleaned is less than a required for the discharge of liquid minimum speed. Thus, by means of the cleaning roller, a dry cleaning can be carried out at a first speed without unwanted liquid leaking from the hollow body.
  • the cleaning device is a wet cleaning device, wherein the cleaning roller is designed to release a first amount of liquid from the liquid space of the hollow body at a first speed corresponding to surface treatment by means of the cleaning roller and at a self-cleaning of the cleaning roller appropriate, In particular, higher, second speed to release a leakage of a second amount of liquid from the liquid space.
  • the wet cleaning device has two different speed levels for the rotation of the cleaning roller. During a surface treatment by means of the cleaning roller, the cleaning roller rotates at a first speed, whereupon a quantity of liquid corresponding to the current equilibrium of forces is dispensed from the liquid space.

  • the specified minimum speed of 150 revolutions per minute stands out clearly from only accidental rotation of the cleaning roller during transport of the cleaning device. Likewise, this minimum speed also exceeds the speed of the cleaning roller at a mere displacement of the cleaning device over the surface to be cleaned. Rather, the specified speed range of 150 revolutions per minute to 3,000 revolutions per minute corresponds to the usual rotational speeds of the cleaning roller during a machining operation for cleaning the surface or for self-cleaning of the cleaning roller of adhering dirt.
