Abstract
Description
- The present application is a continuation of U.S. patent application Ser. No. 13/681,899, filed on Nov. 20, 2012, which is hereby incorporated by reference in its entirety.
- 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.
- A pool cleaning vehicle is provided comprising a body mounted on wheels such that it can roll over a surface. The body carries a water inlet port and a water outlet port with the inlet port being located on the bottom of the body. It also has a filter mechanism interposed between the inlet and outlet ports. An electric motor mounted is on the body between the two sides of the body with a shaft extending out of it with a propeller mounted on the shaft. The motor is mounted such that the propeller expels water out of the outlet port. A roller brush extends between the same two sides of the body generally transverse to the direction of travel of the vehicle and the roller brush is rotated by the electric motor via a linkage. In another embodiment, a pool cleaning vehicle includes a body mounted on wheels such that it can roll over a surface. The body includes water inlets and outlet ports. The inlet ports are located on the bottom of the body, and the outlet ports direct water flow in two opposing directions. A filter mechanism is interposed between the inlet and outlet ports. An electric motor is mounted on the body between the two sides of the body operatively rotating a propeller. The motor is mounted such that the propeller expels water out of one of the outlet ports. A roller brush extends between the same two sides of the body generally transverse to the direction of travel of the vehicle. The roller brush is rotated by the electric motor via a linkage.

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. - Referring to
FIG. 1 , there is shown one embodiment of a cleaning vehicle 10 with a poweredroller brush 20. It is suspended onfront wheels 30 andback wheels 40 at a height such that thescraping members 29 of its poweredroller brush 20 contact the surface on which thewheels members 29 just make contact with the surface on which thewheels - 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 inFIG. 3 ) receives power frompower cord 60 which connects to a remote power source. The vehicle is propelled by the expulsion of the liquid from one of itsoutlet 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 itsinlet ports 72 visible inFIG. 2 and expelling it out one of itsoutlet ports 70 visible inFIGS. 1 and 4 . The water movement is effected by electric motor 80 visible inFIG. 3 turning itspropellers 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 viafloating cable 60. Thepropellers 82 and 84 are driven by the motor 80 to expel liquid out of either theoutlet port 70 above the front wheels 30 (visible inFIG. 1 ) or the outlet port 70 (visible inFIG. 4 ) above theback 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 theroller brush 20. The electric motor 80 is equipped with a gear box 86 which translates the rotation of the electric motor 80 by 90.degrees, 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 apulley 22 on adrive transfer shaft 23. Thisdrive transfer shaft 23 is supported by anelongated bushing 24. Thisdrive transfer shaft 23 carries anotherpulley 25 at its other end which transmits force to a second drive belt 26. This drive belt 26 is looped over afourth pulley 27 which is free to rotate. This drive belt 26 frictionally engages theaxle 28 of theroller brush 20. This facilitates slippage between theroller 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 theroller 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 thefront wheels 30 are both mounted to the vehicle 10 viasuspension brackets 34. This arrangement allows thefront wheels 30 to be mounted without a transverse axle, thereby facilitating the mounting of theroller brush 20 between thefront wheels 30. Among other advantages this positions theroller brush 20 to aid the vehicle in climbing the side walls of the reservoir being cleaned. The suction created through theinlet ports 72 by the action of thepropellers 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 anoutlet port 70 will propel the vehicle up the side wall but the roller brush 20 aids in this climbing operation. - Referring to
FIG. 4 , atelescoping handle 50 makes it easier to place thevehicle 20 into and withdraw it from the reservoir in which it is to operate. The handle comprises twoside arms 52 and across arm 54, which can be readily grasped. Theside arms 52 are accommodated inreceiver shafts 56 which have ends 58. Theshafts 56 are long enough that thehandle 50 may be fully retracted so that it is flush with the vehicle as can be seen inFIG. 1 . Theside arms 52 and theshafts 56 interact such that thehandle 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 theside arms 52 out of theshafts 56. - Referring to
FIG. 4 , the design of the vehicle with longitudinal filters 90 readily accommodates theshafts 56. The vehicle 10 serves its cleaning function by drawing fluid containing dirt and debris into itsinlet ports 72 and subjecting this fluid to a filtering action before expelling it out of itsoutlet ports 70. The positioning of the electric motor 80 and itspropellers 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 theshafts 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.
