Description

    BACKGROUND
  • There are robotic cleaning vehicles which traverse the bottom of swimming pools and other large liquid containers submerged in the contained liquid, drawing in liquid from ports in their bottoms, passing this liquid through filters in the body of the vehicle and expelling the filtered liquid back into the large container, typically a swimming pool. These vehicles typically travel on wheels which suspend the body of the vehicle above the bottom of the container.

  • FIG. 1 is a perspective view of a cleaning vehicle.
  • FIG. 2 is a perspective view of the bottom of a cleaning vehicle.
  • FIG. 3 is a perspective view of the interior drive train elements of the powered roller brush of a cleaning vehicle.
  • FIG. 4 is a perspective view of a partial cut away of a cleaning vehicle with an extended telescoping handle.
  • DETAILED DESCRIPTION
  • Referring to FIG. 1, there is shown one embodiment of a cleaning vehicle 10 with a powered roller brush 20. It is suspended on front wheels 30 and back wheels 40 at a height such that the scrapping members 29 of its powered roller brush 20 contact the surface on which the wheels 30 and 40 travel. In one embodiment, then distal ends of members 29 just make contact with the surface on which the wheels 30 and 40 travel, to minimize the load on the motor as will be discussed below.
  • In one embodiment the vehicle may be placed in and removed from its use environment by a telescoping handle 50. Its internal electric motor 80 (shown in FIG. 3) receives power from power cord 60 which connects to a remote power source. The vehicle is propelled by the expulsion of the liquid from one of its outlet ports 70. The vehicle 10 functions to clean the surfaces of a large liquid reservoir, such as a swimming pool, which are covered by the liquid stored in the reservoir. The vehicle 10 is submerged in the stored liquid and is then propelled by taking in liquid through its inlet ports 72 visible in FIG. 2 and expelling it out one of its outlet ports 70 visible in FIGS. 1 and 4. The water movement is effected by electric motor 80 visible in FIG. 3 turning its propellers 82 and 84. The direction in which the vehicle 10 is propelled is determined by the direction of rotation of the electric motor 80 which is in turn controlled by signals received from the power supply via floating cable 60. The propellers 82 and 84 are driven by the motor 80 to expel liquid out of either the outlet port 70 above the front wheels 30 (visible in FIG. 1) or the outlet port 70 (visible in FIG. 4) above the back wheels 40. In accordance with the well known physics concept of action and reaction the vehicle 10 will be propelled in a direction opposite to that in which the liquid is expelled.
  • As can be seen in FIG. 3, the electric motor 80 is also used to power the roller brush 20. The electric motor 80 is equipped with a gear box 86 which translates the rotation of the electric motor 80 by 90° or some other angle and also reduces the number of rotations in some fixed ratio such as 1:30 or any other ratio. A common way to effect these changes is with a combination of a combination of a worm gear with a spur gear. However other types of mechanical connection may be used. The gear box has a takeoff spindle 88 which carries a pulley 89 which transmits force to a gear train or drive belt system 21. The drive belt 21 in turn transmits this force to a pulley 22 on a drive transfer shaft 23. This drive transfer shaft 23 is supported by an elongated bushing 24. This drive transfer shaft 23 carries another pulley 25 at its other end which transmits force to a second drive belt 26. This drive belt 26 is looped over a fourth pulley 27 which is free to rotate. This drive belt 26 frictionally engages the axle 28 of the roller brush 20. This facilitates slippage between the roller brush 20 and ultimately the electric motor 80, should the roller brush encounter some type of obstacle like a large piece of debris on the surface being cleaned. This avoids the vehicle 10 becoming stalled by such obstacles and allows the vehicle 10 to pass over them. Where a gear train is used in place of a drive belts, a clutch may be positioned between the motor and the roller brush 20. The clutch will allow the motor continue to rotate the propellers if the roller brush is obstructed from rotating by debris within the pool.
  • The roller brush 20 and the front wheels 30 are both mounted to the vehicle 10 via suspension brackets 34. This arrangement allows the front wheels 30 to be mounted without a transverse axle, thereby facilitating the mounting of the roller brush 20 between the front wheels 30. Among other advantages this positions the roller brush 20 to aid the vehicle in climbing the side walls of the reservoir being cleaned. The suction created through the inlet ports 72 by the action of the propellers 82 and 84 tends to hold the vehicle to non-horizontal and even vertical side walls so long as these side walls are submerged in liquid. The expulsion of liquid from an outlet port 70 will propel the vehicle up the side wall but the roller brush 20 aids in this climbing operation.
  • Referring to FIG. 4, a telescoping handle 50 makes it easier to place the vehicle 20 into and withdraw it from the reservoir in which it is to operate. The handle comprises two side arms 52 and a cross arm 54, which can be readily grasped. The side arms 52 are accommodated in receiver shafts 56 which have ends 58. The shafts 56 are long enough that the handle 50 may be fully retracted so that it is flush with the vehicle as can be seen in FIG. 1. The side arms 52 and the shafts 56 interact such that the handle 50 can support the free air weight of the vehicle 10. This is accomplished by providing one or the other or both with locking mechanisms to limit the travel of the side arms 52 out of the shafts 56.
  • Referring to FIG. 4, the design of the vehicle with longitudinal filters 90 readily accommodates the shafts 56. The vehicle 10 serves its cleaning function by drawing fluid containing dirt and debris into its inlet ports 72 and subjecting this fluid to a filtering action before expelling it out of its outlet ports 70. The positioning of the electric motor 80 and its propellers 82 and 84 longitudinally above the centerline of the vehicle allows the placement of the filters 90 parallel to this centerline and in one embodiment filters 90 are angled to accommodate the shafts 56.
  • The outlet ports 70 are angled a bit upward from horizontal. This provides a downward force on the vehicle which aids in the vehicle climbing the side walls of the reservoir being cleaned.
  • While only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
