Definitions

  • the present invention relates to a machine for washing floors.
  • a known type comprises a washing unit, which houses a motor for actuating one or more circular brushes, acting on a surface to be cleaned, typically a floor, and means for releasing a cleaning liquid with a relative filling tank, means for sucking in the cleaning liquid after being rubbed onto said surface and a relative collection tank.
  • Such machines further comprise a support frame to which the washing unit is connected, allowing the movements thereof by means of wheels.
  • a handlebar or handle is also connected to the machine body for an operator to command and control the machine.
  • the motor drives a pair of brushes, wherein each of the brushes is symmetrically coupled to a respective conveying apparatus for conveying the dirt into the container to form a respective mechanical recovery unit for the solid and liquid dirt.
  • each conveying apparatus for conveying the dirt into the container comprises a conveyor belt driven by the motor.
  • a further important advantage of the described solution is that it allows excellent washing performance, also on carpets.
  • a further advantage given by the mechanical recovery for the dirt is that it also offers a pre-brushing function, thus allowing the drying function of the rubber blades to be maintained, which, as happens with traditional washer-driers, is constantly challenged by solid particles of dirt lodged between the blades, with a consequent loss in the drying performance.
  • the machine 10 comprises a support structure 14 for a washing unit 12.
  • the support structure 14 comprises an adjustable handle 15 provided with a handgrip 20.
  • the handle 15 can take different inclined positions, exploiting the presence of the hinge 17.
  • a suction unit 40 is positioned on the handle 15.
  • the suction unit 40 is connected to a suction recovery tank 50 by means of a suction tube 45.
  • a battery 30 is positioned on the handle 15 to provide the washing machine 10 with operational autonomy.
  • the washing unit 12 comprises a motor 100, which drives at least one brush 72,74 and at least one apparatus 92,94 for conveying the solid or liquid dirt.
  • Each rotating brush 72,74 lifts both the liquid dirt and the solid dirt and projects it onto the conveying apparatus 92,94, which rotates in the opposite direction to the brush 72,74 and takes said dirt, by means of a centrifugal force, into a container 90 associated with the washing unit 12.
  • the washing unit 12 has a symmetrical structure formed by a pair of brushes 72,74 each of the brushes 72,74 is coupled to a respective conveying apparatus 92,94 for conveying the dirt into the container 90 to allow the washing machine 10 to function in both directions of travel.
  • the conveying apparatus 92,94 for conveying the dirt into the container 90 comprises a conveyor belt driven by the motor 100.
  • Each conveyor belt 92,94 is associated with a respective scraping member 102,104 adapted to recover the solid or liquid dirt and convey it into the container 90.
  • FIGS 4 and 7 offer additional views of the machine 10 from different angles to better appreciate the overall structure thereof.
  • the washing unit 12 further comprises a tank 80 for containing a liquid detergent, in particular an aqueous solution of a detergent for floors ( figures 5 and 6 ).
  • the dispensing of the detergent during operation of the machine 10 allows the dirty liquid to be collected, in an immediately successive step, by means of the rotating brushes 72,74, and deposited on the active surfaces of the conveyor belts 92,94, and then collected by the respective scraping members 102,104 and finally deposited in the container 90.
  • the suction unit 40 is designed to allow a bi-directional suction function, enabling the machine 10 to work in both directions since the operator can adjust the handle 15, exploiting the hinge 17.
  • This feature allows the opposite ends of areas where the floor is being cleaned to be reached easily.
  • the motor 100 is placed below the container 90 and it is placed between two symmetrical mechanical recovery units for the solid and liquid dirt, each comprising a respective conveying apparatus 92,94 associated with the relative brush 72,74.
  • This element complex is contained inside the washing unit 12 so that the suction unit 40 can act symmetrically on the elements of the washing unit 12, allowing the machine 10 to work in both directions.
  • the washing unit 12 also comprises a squeegee 60, or wiping member, which cooperates with the washing unit 12 to increase the performance of the machine 10.
  • the machine 10 concentrates the concept of mechanical recovery for dirt with the concept of bi-directional suction into highly reduced dimensions with respect to the market standard.
  • the configuration of the machine 10 allows a significant reduction in the maintenance of the suction blades.
