Definitions

  • the invention relates to a surface cleaning utensil, such as a robot (vacuum) cleaner or a nozzle for a canister or stick vacuum cleaner.
  • a surface cleaning utensil such as a robot (vacuum) cleaner or a nozzle for a canister or stick vacuum cleaner.
  • the invention also relates to a vacuum cleaner provided with the nozzle.
  • US9414729 discloses a robotic vacuum cleaner that includes a driving mechanism, a fan, an electronic control, sweeping brushes and a housing with a front side extending in the transverse direction and a longitudinal direction perpendicular thereto.
  • An underside of the housing has a suction opening that extends in the transverse direction.
  • At least four sweeping brushes are provided, where at least two of the four sweeping brushes are disposed on each side of the suction opening such that at least one sub-region of the suction opening remains free from sweeping brushes, as viewed from the front side.
  • the at least two of the four sweeping brushes provided on each of the two sides of the suction opening are driven in an identical direction of rotation.
  • the bristles are mounted on the underside of a sweeping disk.
  • a surface cleaning utensil comprising a wet cleaning unit having a wetting unit and a brush unit for brushing a surface wetted by the wetting unit, the brush unit having brush having a plurality of brush elements (e.g. bristles) substantially perpendicular, i.e. at an angle of at least 45°, and preferably at least 70°, to a surface to be cleaned, and a driving unit for driving the brush to move in a plane substantially parallel, i.e. at an angle of at most 45°, and preferably at most 20°, to the surface.
  • Embodiments of such a surface cleaning utensil are particularly suitable for cleaning stains on the surface to be cleaned.
  • the brush unit comprises a plurality of rotating brushes having a rotation axis at an angle of at least 45°, and preferably at least 70°, to the surface to be cleaned, wherein at least 50% of an area defined by a circumference of each brush is provided with brush elements.
  • adjacent brushes have opposite rotation directions.
  • the brushes comprise gear-shaped elements.
  • the driving unit is arranged for causing a translational movement of the brush with respect to the surface cleaning utensil.
  • the wet cleaning unit further comprises a drying pad, the brush unit being positioned between the wetting unit and the drying pad.
  • the surface cleaning utensil further comprises an air inlet located before the wet cleaning unit in a motion direction of the surface cleaning utensil.
  • a vacuum cleaner comprising a nozzle formed by such a surface cleaning utensil, a suction unit for generating an air flow through the air inlet, and a dirt separation unit for separating dirt from the air flow.
  • Fig. 1 shows an embodiment of a surface cleaning utensil in accordance with the present invention.
  • the embodiment is a robot vacuum cleaner having an air inlet at the front, formed by a vacuuming nozzle N.
  • the embodiment further comprises a brush unit BU comprising a plurality of adjacent brushes B each having multiple brush elements. Preferably, the adjacent brushes B do not leave gaps between adjacent brushes.
  • the brush unit BU is part of a wet cleaning unit WCU that further comprises a wetting unit WP formed by a wetting pad.
  • the wet cleaning unit WCU may include a drying pad DP.
  • the wetting pad WP is before the brush unit BU, while the drying pad DP is behind the brush unit BU, so that the brushes B act on a surface that has been wetted by the wetting pad WP.
  • the surface may alternatively be wetted by a wetting unit WP that sprays a cleaning fluid on the surface and/or on the brush B.
  • the wetting pad WP and the drying pad DP are preferably made as described in WO2018/153706 (attorneys' reference 2017P01665WO), incorporated herein by reference, which also describes a single tank that can be simultaneously used for clean water and dirty water, which single tank is preferably used in the surface cleaning utensil of the present invention.
  • the brushes B rotate. They may rotate in a continuous rotation. Alternatively, they may regularly reverse the rotation direction. Adjacent brushes B may have opposite rotation directions. While each brush B may be driven by a separate motor, it is alternatively possible that only one or two motors are used for driving the brush unit BU, while the other brushes B are driven by gears, e.g. as shown in Fig. 3 , which shows adjacent brushes B having gear-shaped elements G. In the embodiment of Fig. 2 , it would be possible that only brushes B2 and B5 are directly driven by respective motors, while the rotation of the other brushes B1, B3, B4, B6 results from the gear-shaped elements G.
  • the rotation speed is preferably at least 100, and more preferably at least 800, rotations per minute.
  • each brush B has at least 10,000 nylon bristles BE, e.g. at least 15,000.
  • the length of the bristles BE is preferably between 3 and 5 mm, e.g. 4.2 mm.
  • the brushes B are driven to carry out a translational movement compared to the surface cleaning utensil, e.g. by a laterally moving magnet.
  • the magnets result in an oscillation frequency of at least 100 Hz.
  • the brushes B have respective rotation axes substantially vertical to the surface to be cleaned, i.e. each rotation axis is at an angle of less than 45°, and preferably less than 30°, from an angle perpendicular to a surface to be cleaned.
  • each brush B has a plurality of brush elements BE substantially parallel to the rotation axis.
  • substantially parallel allows for a small deviation of up to 30°, and preferably not more than 20°.
  • the brush elements BE may be bristles, like shown in Fig. 3 , or they may have a shape like shown in Fig. 1 .
  • a front end of the wet cleaning unit WCU has a ramp R for thresholds to easier cope with thresholds. For the same reason, also a front end of the vacuuming nozzle N is slanted.
  • Fig. 2 shows an embodiment of a brush unit BU for use in a surface cleaning utensil in accordance with the present invention, having 6 adjacent brushes B1, B2, B3, B4, B5 and B6 mounted at distances less than the maximum diameter of each brush.
  • a vacuum cleaner comprising a nozzle formed by a surface cleaning utensil having a wet cleaning unit with a plurality of brushes as described above, and an air inlet, a suction unit (e.g. a fan) for generating an air flow through the air inlet, and a dirt separation unit (e.g. a cyclone or dust bag) for separating dirt from the air flow.
  • a suction unit e.g. a fan
  • a dirt separation unit e.g. a cyclone or dust bag
  • the brush may have a rectangular shape, e.g. when it is only subject to a translation movement. If a control unit inside the robot cleaner is able to recognize the presence, and preferably also the severity of stains on the surface to be cleaned, the driving unit can be controlled in dependence of the result of this recognition.
  • any reference signs placed between parentheses shall not be construed as limiting the claim.
  • the word "comprising" does not exclude the presence of elements or steps other than those listed in a claim.
