Turbine-Powered Pool Scrubber

Abstract

A pool cleaning tool includes a front housing and a rear housing coupled together, an intake, an outlet, a turbine disposed within the front and rear housings, and a three-way diverter valve proximate the intake. The tool includes an abrasive member, rigidly coupled to the turbine, mounted outside the front and rear housings for rotation with the turbine. The three-way diverter valve has an on position in which water drawn into the intake is communicated into the tool, up to the turbine, and then out the outlet, thereby imparting rotation to the turbine and to the abrasive member.

DETAILED DESCRIPTION

(6) Reference is now made to the drawings, in which the same reference characters are used throughout the different figures to designate the same elements. FIGS. 1-4 illustrate a new and improved hand-held cleaning tool 12 which uses available hydro power of the pool pump and filter system and a detachable abrasive member 6. As identified in the description of the drawings, the tool includes a front housing 1, a rear housing 2, a three-way diverter valve 3 (such as a ball valve, butterfly valve, spear valve, gate valve, diaphragm valve, globe valve, check valve, and solenoid valve), a hydro or water turbine 4 (such as react turbines including a VLH turbine, Kaplan turbine, propeller turbine, bulb turbine, Straflo turbine, Tyson turbine, and Gorlov turbine, or impulse turbines including a waterwheel turbine, Pelton turbine, Turgo turbine, Crossflo turbine, Michell turbine, Banki turbine, Ossberger turbine, Jonval turbine, reverse overshot turbine, Archimedes screw turbine, and Barkh turbine), a grommet 5, a detachable abrasive member 6, a rear turbine bearing 7, a front turbine bearing 7A, a silicone rubber seal 8, and self-tapping screw pilot holes 9 and 9A. The abrasive member 6 is adapted to be and is actually connected to the shaft 11 of the hydro turbine 4. In this preferred embodiment, the abrasive member 6 is threaded directly into the hydro turbine 4 shaft 11 housed in the handheld tool 12. The abrasive member 6 may use various grades of abrasion and has a substantially cylindrical and/or flat outer surface. The abrasive member 6 is mounted on the drive shaft 11 of the hydro turbine 4 and/or a chuck to secure the detachable abrasive member 6. This embodiment of the invention is effective for removing especially thick solid deposits of calcium and plaster stains which do not respond to treatment with a bristle-type brush.

(7) To use the tool 12 for cleaning the vertical side tile walls of a swimming pool, it is most beneficial for the operator to stand in the pool in order for the abrasive member 6 to have direct contact with the surface being cleaned. It is preferred that the abrasive member 6 be above pool water level. The operator actuates the hydro powered turbine 4 by controlling the three-way diverter valve 3 on the device in order to rotate the abrasive member 6. FIG. 1 illustrates the three-way diverter valve 3 in the ON position; when a suction hose extending from the pool pump and filter system is applied to the outlet 16 and the pump system is activated, the water is drawn up through the pool water intake 15. Water is drawn up through the intake 15, into the tool 12 between the front and rear housings 1 and 2, up to an end of the tool 12 which is opposite the intake 15 (and which is where the turbine 4 is located), and then back down and out the outlet 16, moving substantially parallel to and in an opposite direction to the water drawn into the tool 12 at the intake 15. This movement of water activates the rotation of the turbine 4. The operator may control the RPM or revolutionary speed of the turbine with the three-way diverter valve 3, moving from a diverted position, in which the water is not passed up to the turbine The operator may then move the tool 12 slowly around the perimeter of the pool until the desired perimeter of the pool has been cleaned. In order to clean different types of surfaces, the operator may substitute different types of abrasive members 6 and may hold the tool handle 14 (as shown in hand in FIG. 4) in different positions relative to the surface. The interchangeable abrasive members 6 include various grade types for the removal of calcium build-up to polishing pool tile.
