Definitions

  • the present invention relates to a floor cleaning machine with a chassis for moving the floor cleaning machine over a floor surface to be cleaned.
  • two or more spray nozzles are usually provided on the brush element in the prior art, in order to ideally humidify the work area depending on the respective direction of rotation of the brush element.
  • one of the two spray nozzles moistens that area located in front of the brush element in the cleaning direction, in which the free ends of the bristles of the brush element due to its inclination come into contact with the bottom surface.
  • the other of the two spray nozzles points laterally out of the work area and does not effectively contribute to the humidification of the relevant work area.
  • a floor cleaning machine with a vehicle frame, on which a chassis is provided for moving the floor cleaning machine on a floor surface to be cleaned, with a support arm extending between a first and a second end, wherein the support arm with the first End movable on the vehicle frame is mounted so that the second end extends away from the vehicle frame, with a brush member having a brush body from which extend one or more engagement elements, the free ends are arranged in a cleaning plane and which are provided with the to be cleaned Engages the brush body about a perpendicular to the cleaning plane extending axis of rotation rotatably mounted on the second end of the support arm, wherein the brush body on the pointing away from the cleaning surface top has a in a plane perpendicular to the axis of rotation about this rotating ring portion, with a drive means for rotating drive of the brush body about the axis of rotation, with a extending between a first and a second end of the pivot arm which is pivotally mounted at its first end about a pivot
  • the pivotable pivot arm is pivoted upon rotation of the brush member in that of the two end positions in which the spray nozzle moistening that area of the floor surface to be cleaned, seen in the cleaning direction before the section of Bottom surface is below the brush element, in which the free ends of the engagement or bristle elements are in contact with the bottom surface.
  • the spray nozzle provided on the swivel arm always automatically acts on the section which in the further course of the Cleaning process comes into contact with the brush element.
  • the system thus reacts automatically, without the user having to intervene, to a change in the direction of rotation of the brush element.
  • the brush element is arranged together with swivel arm and spray nozzle, now for example moved from the left edge of the track of the floor cleaning machine to the right edge and is automatically changed if necessary, the direction of rotation of the brush element, the Dirt continues to the center of the machine and into the sweeping area.
  • the pivoting arm also moves away from the one end position toward the other end position as the direction of rotation changes due to the frictional engagement of the contact element with the ring section. In this way, when the direction of rotation of the brush element changes in a purely mechanical manner, it is ensured that the one spray nozzle returns to a position in which it humidifies the section of the bottom surface which comes into contact with the brush element later in the cleaning process.
  • the invention is not limited to such arrangements of brush elements and spray nozzles in which the spray nozzles are used for wetting the surface for dust binding, but the Invention can also be used where spray nozzles for applying cleaning liquid is used.
  • the one or more engaging elements may be formed in particular as bristle elements, in which context it is also clear that the term "bristle elements" in the context of the present invention is to be interpreted broadly and should not only include bristles in the strict sense, but thereby also, for example, strip-shaped elements elastic material to be detected, which have a cleaning effect. However, it is also possible for an integrally formed engagement element of an elastic material to extend away from the brush body.

  • the holding arm can in particular be mounted on the vehicle frame in such a way that it is pivotably mounted in front of the vehicle frame in the direction of cleaning, so that edge regions lying in the direction of travel in front of the floor cleaning machine can be grasped by the brush element. The pivoting thereby makes it possible for the holding arm with the brush element attached thereto to be moved easily between the left and right edge regions of the travel path.
  • the support arm comprises a first and a second arm member, wherein the two arm members are pivotally connected to each other about a second axis which is parallel to the first axis.
