BACKGROUND

This invention relates to providing pool-cleaning systems. More particularly, this invention relates to providing a system for improved storage and deployment of pool vacuuming components.
Typically, a random-motion pool vacuum is coupled to a hose that is coupled to the central pool vacuum pump. The pool vacuum pump and hose are placed in the pool, primed for use, and must be removed from the pool and drained of water so that the pool can be used for swimming. This is very labor-intensive and time-consuming.
In addition, it is highly preferred to store the vacuum hose in an uncoiled rather than a coiled configuration. Storing the hose in an uncoiled configuration improves in-service performance by limiting hose hysteresis, which is the tendency of the hose to retain a coiled shape once deployed. Some manufacturers of pool cleaning heads specifically void the operational warranty of the device if the vacuum hose is stored in a coiled configuration. Currently, uncoiled storage of a vacuum hose is, at best, haphazard, requiring the hose to be stored within the general area of the pool, for example, uncoiled on the surface of the pool deck or nearby landscape area.
Therefore, a need exists for a system that can deploy a pool vacuum and hose automatically, and retract the pool vacuum and hose automatically. Further, a need exists for a vacuum system that remains continuously primed, preferably storing the hose in an uncoiled or semi-linear configuration.

OBJECTS AND FEATURES OF THE INVENTION

A primary object and feature of the present invention is to provide pool-cleaning systems to overcome the above-described problems. A further primary object and feature of the present invention is to provide a pool-cleaning system that automatically deploys a pool vacuum, and automatically retracts the pool vacuum.
It is a further object and feature of the present invention to provide such a system that can be run entirely on waterpower provided by a connection to the low-pressure side of a pool circulation pump. It is yet another object and feature of the present invention to provide such a system that is stored underwater, to maintain the vacuum hose in a primed (water-filled) state.
It is another object and feature of the present invention to provide such a system that stores an underwater hose in an uncoiled and substantially linear arrangement. It is yet another object and feature of the present invention to provide such a system having an underwater hose reel as an alternate preferred embodiment.
It is an additional object and feature of the present invention to provide such a system including methods of cleaning pools.
A further primary object and feature of the present invention is to provide such a system that is efficient, inexpensive, and handy. Other objects and features of this invention will become apparent with reference to the following descriptions.

DETAILED DESCRIPTION OF THE BEST MODES AND PREFERRED EMBODIMENTS OF THE INVENTION

FIG. 1 shows a side view, in partial section, of automatic vacuum assembly 110 of pool-cleaning system 100, retracted into pool-wall housing 120, according to a preferred embodiment of the present invention. FIG. 2 shows a plan view of a water-filled swimming pool 102 incorporating pool-cleaning system 100 of FIG. 1.
In the following specification, the terms “suction” and “vacuum” are used interchangeably to define conditions of decreased fluid pressure within the fluid (water) transporting interstices of pool-cleaning system 100 (generally associated with plumbing assemblies on the “suction side” (low-pressure side) of a water circulation pump). In the present disclosure, “suction side” refers to the pipes and fittings that draw water out of swimming pool 102 to be filtered
Preferably, pool-cleaning system 100 comprises an automatic vacuum-cleaning system that automatically deploys swimming pool vacuum hose 112 with an attached pool vacuum head 113, to clean the interior of the pool of debris, and automatically retracts pool vacuum head 113 after sufficient cleaning has taking place.
Automatic vacuum assembly 110 is preferably organized around three principal components comprising housing 120, which is preferably installed in the side of swimming pool 102 at the time of pool construction, control assembly 108, which is placed in main housing 120 by the user, and a long storage tube 111 (connected to main housing 120) that is preferably used to store the swimming pool vacuum hose 112 when it is not in use.
Preferably, pool-cleaning system 100 operates utilizing fluid pressure generated by the circulation of water within the plumbing/filter system of swimming pool 102. Preferably, pool-cleaning system 100 operates by utilizing the force of moving water generated by a coupling to the suction side of the plumbing/filter system of swimming pool 102. The device most often used in pool plumbing/filter systems to circulate water within swimming pools is an electrically driven pump, identified herein as circulation pump 130, as shown (and embodying herein wherein the at least one low-pressure fluid source comprises at least one fluid circulation pump adapted to circulate the water of such at least one pool of water). It should be noted that in the diagrammatic illustration of FIG. 2, a residential size pool having a single circulation pump 130 is shown, however, larger pools, such as competition pools, municipal pools, etc., may comprise multiple pumps and/or multiple automatic vacuum assemblies 110.
Automatic vacuum assembly 110 is shown in FIG. 1 in a retracted (stored state) where the operational components of automatic vacuum assembly 110 are contained substantially within main housing 120 and storage tube 111 as shown. Preferably, the operational components of automatic vacuum assembly 110 are contained substantially within housing 120 when circulation pump 130 is off, as shown, and automatically deploy into pool 102 through door 122 when circulation pump 130 is operating. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as advances in technology, user preference, etc., other automatic vacuum assembly components, such as timers, sensors, remote controls, chemical addition systems, etc., may suffice.
Preferably, housing 120 (at least embodying herein at least one second housing comprising at least one hollow interior adapted to house such at least one first housing) is constructed as an integral structure of swimming pool 102, preferably position under a portion of pool deck 103 adjacent the peripheral wall 105 of swimming pool 102, as shown (at least embodying herein wherein such at least one second housing is prepositionally fixed relative to the at least one pool of water). Preferably, the interior of housing 120 is in fluid communication with the water contained within swimming pool 102, as shown. Preferably, automatic vacuum assembly 110 is located within housing 120 at a position submerged below the waterline of the pool, as shown. Similarly, storage tube 11I preferably extends outwardly from swimming pool 102 at an elevation adapted to maintain vacuum hose 112 below the waterline of the pool (at least embodying herein wherein such at least one tubular sleeve is adapted to maintain the at least one substantial portion of the at least one vacuum hose submerged within water from such at least one pool of water). Preferably maintaining automatic vacuum assembly 110 (including vacuum hose 120) in a submerged condition eliminates the need to physically prime (fill with water to remove air) vacuum hose 112 prior to each use, as typically required to properly operate liquid circulation pumps. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as advances in technology, user preference, etc., other arrangements, such as placing the housing underneath the pool, having a dry housing, and keeping the hoses filled with water by other means, other housing dimensions, etc., may suffice.
Preferably, the interior of housing 120 extends through peripheral wall 105, as shown (at least embodying herein at least one first passage adapted to provide fluid communication between such at least one hollow interior and the at least one pool of water). Preferably, the opening formed by the extension of housing 120 through peripheral wall 105 is covered by a pivoting door 122, as shown.

A problem common in the use of plastic vacuum hoses used in maintaining swimming pools is hose hysteresis. Hose hysteresis is the tendency of the hose material to retain the shape in which it was stored prior to use. For example, if a hose is stored in a conventional coiled arrangement, on deployment, the hose will have a tendency to retain the coiled shape thus reducing the ability of the hose to move freely with the operation of the pool equipment (e.g. pool vacuum head 113). To significantly reduce hose hysteresis problems, storage tube 111 is preferably adapted to store vacuum hose 112 in an uncoiled and substantially linear configuration, as shown.

Preferably, distal end 117 comprises removable cap 119 for service access to the interior of storage tube 111, as shown (at least embodying herein wherein such at least one second open end comprises at least one removable cover adapted to removably cover such at least one second open end). To further ensure that no hose memory problems arise, the hose is mechanically turned slightly with each deployment so that it is stored in a different position after each use.
Preferably, storage tube 111 is constructed from a plurality of interconnectable tubular sections, preferably tubular segments having individual lengths of about five feet and an interior diameter of about four inches (at least embodying herein wherein such at least one tubular sleeve comprises at least one plurality of interconnectable segments adapted to provide segmented assembly of such at least one tubular sleeve). Preferably, the builder of pool 102 assembles the segments to form a continuous and substantially watertight underground storage tube, as shown. Preferably, tube 111 is constructed from at least one durable material suitable for direct burial within soil 106, as shown. Tube 111 is preferably constructed from a plastic material with Acrylonitrile Butadiene Styrene (ABS) being most preferred. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as user preference, intended use, etc., other storage pipe materials, such as Poly Vinyl Chloride (PVC), High Density Polyethylene (HDPE), low and medium density polyethylenes (PE), etc., may suffice. Preferably, the individual segments of tube 111 of are permanently joined during construction, most preferably by chemical bonding. Preferably, to further ensure no hose memory problems arise; vacuum hose 112 is mechanically turned slightly with each deployment so that on retraction it is stored in a different position after each use.

FIG. 7 shows a top view of hydraulic drive turbine 240 of control assembly 108 according to the preferred embodiment of FIG. 1. FIG. 8 shows a side view of turbine housing 144 of hydraulic drive turbine 240. FIG. 9 shows a front view of turbine impeller 146 while FIG. 10 shows a top view of turbine impeller 146 of hydraulic drive turbine 240. The following teachings of the specification make particular reference to FIG. 7 through FIG. 10 and general reference to the prior figures. Hydraulic drive turbine 240 is preferably adapted to convert a flow circulating pool water to a usable mechanical rotation. Preferably, hydraulic drive turbine 240 comprises a rotating turbine impeller 146 situate within hollow circular cavity 143 of ducted turbine housing 144, as shown. Preferably, turbine housing 144 comprises at least one, preferably six funnel-shaped inlets 145, adapted conduct pool water to hollow circular cavity 143, as shown. Preferably, a first side of each funnel-shaped inlet 145 is aligned approximately tangent to the inner diameter B of hollow circular cavity 143, as shown. The opposite side is preferably set at an angle about 10-degrees divergent from the first, as shown. Each funnel-shaped inlet 145 of the example turbine of FIG. 7 comprises a minimum passage size of about one-quarter square inch. The example turbine housing of FIG. 7 comprises an outer diameter A of about six inches and an inner cavity diameter B of about 4½ inches.
Preferably, the outer diameter of turbine impeller 146 is sized to fit closely within hollow circular cavity 143 while maintaining appropriate rotational clearances during operation. In the example turbine impeller of FIG. 7, the backing disk 147 of turbine impeller 146 comprises a thickness C of about one-eighth inch. Preferably, the front face of backing disk 147 comprises an array of projecting impeller blades 148, preferably about 18 impeller blades 148, spaced equally about the periphery of the impeller and generally aligned along radius lines of the disk, as shown. Preferably, each planar side of impeller blade 148 comprises a surface area of slightly less than about one-half square inch.
Preferably, hub 149 of turbine impeller 146 is adapted to receive drive shaft 203 (as best illustrated in FIG. 11). Preferably, drive shaft 203 is rigidly fixed to hub 149 by set screw 205, as shown. A rear cover plate 207 is bolted to turbine housing 144 to complete the assembly, as shown.
In use, hollow circular cavity 143 of hydraulic drive turbine 240 is coupled to suction (vacuum) originating at suction connection 134 of control valve assembly 136 by means of vacuum transfer conduit 206, as shown. When circulation pump 130 is initially activated, a low-pressure condition is generated within hollow circular cavity 143 preferably drawing jets of water through funnel-shaped inlets 145. Preferably, turbine impeller 146 is forcefully rotated by the impact of the incoming water against impeller blades 148. Preferably, rotation of turbine impeller 146 results in mechanical rotation of drive shaft 203. Thus, hydraulic drive turbine 240 of such at least one hose deployer at least embodies herein at least one hydraulic motor adapted to power the deploying of the at least one first hose end of the at least one vacuum hose by such at least one hose deployer; such at least one hydraulic motor is in fluid communication with the at least one low-pressure fluid source; and such at least one hydraulic motor is adapted to operate by directing at least one movement of the water of the at least one pool of water toward the at least one low-pressure fluid source
FIG. 11 shows a cut away end view diagrammatically illustrating the interior drive gear arrangements of control assembly 108. FIG. 12 shows a side view of a representative drive wheel 242 of control assembly 108. FIG. 13 shows a side view diagrammatically illustrating the drive gear arrangements of control assembly 108 of FIG. 1.
The deployment and retraction of vacuum hose 112 by control assembly 108 is performed by an internal drive mechanism that preferably comprises drive assembly 241 operated by gear train assembly 208, as shown. Preferably, rotational torque generated by hydraulic drive turbine 240 is transferred along drive shaft 203 to drive gear 210, as shown. Preferably, drive gear 210 is continuously engaged on pivoting gear assembly 212, as shown. Preferably, pivoting gear assembly 212 comprises two gears, first gear 214 rigidly coupled along a connecting shaft to second gear 216, as shown. Preferably, drive gear 210 is continuouly engaged on first gear 214, as shown. Preferably, pivoting gear assembly 212 is mounted within pivoting armature 218, as shown. Preferably, pivoting armature 218 is adapted to movably engage and disengage second gear 216 with clutch input gear 220, as shown.
When circulation pump 130 is activated, the low-pressure vacuum generated actuates start-stop piston 215 (as further described in FIG. 14). The actuation of start-stop piston 215 moves pivoting armature 218 to a position engaging second gear 216, as shown. Tensioning spring 217 is preferably used to bias pivoting armature 218 to a position of gear disengagement that disengages second gear 216 with clutch input gear 220 when circulation pump 130 is deactivated and vacuum pressure is no longer supplied to start-stop piston 215.
Preferably, torque applied by second gear 216 at clutch input gear 220 is delivered to clutch assembly 226 by means of clutch shaft 224, as shown. Preferably, clutch assembly 226 comprises an arrangement of coaxial clutch disks held in frictional contact by clutch spring 228, as shown. Clutch assembly 226 (at least embodying herein at least one limited-slip coupler adapted to provide limited-slip decoupling of at least one mechanical force transferred between such at least one hydraulic motor, such at least one spring tensioner, and such at least one drive assembly) is preferably adapted to decouple rotational torque applied along clutch shaft 224, from both first spring gear 230 and from primary wheel drive gear 222 (when a maximum predetermined level of torque is acheived). Preferably, pluralities of small clutch disks are rigidly fixed to clutch shaft 224, as shown. Preferably, these small clutch disks are interspersed between and frictionally engage; a first set of larger clutch disks 225 firmly coupled to first spring gear 230; and a second independent set of larger clutch disks 227 firmly coupled to primary wheel drive gear 222. Preferably, torque is transferred across clutch assembly 226 so long as friction between the larger clutch disks and smaller clutch disks is maintained. An application of excess torque within clutch assembly 226 overcomes the frictional transfer of force between the disks thereby decoupling the source of the torque force from the remaining components of the system.
Preferably, first spring gear 230 is adapted to transfer torque from clutch assembly 226 to a larger diameter second spring gear 232, as shown. Preferably, second spring gear 232 is adapted to transfer torque to constant torque spring 141 (located within constant torque spring housing 140) through spring drive shaft 236, as shown.
Similarly, primary wheel drive gear 222 is preferably adapted to transfer torque from clutch assembly 226 to drive assembly 241, as shown. Preferably, drive assembly 241 comprises upper and lower drive wheels 242, pivoting armatures 248, secondary wheel drive gear 238, and tension springs 250, as shown. Preferably, primary wheel drive gear 222 transfers torque from clutch assembly 226 to drive assembly 241 by engaging the peripheral sprocket rings 234 of the upper drive wheels 242, as shown. In addition, primary wheel drive gear 222 is preferably adapted to transfer torque to secondary wheel drive gear 238, as shown. Preferably, secondary wheel drive gear 238 transfers operational torque from primary wheel drive gear 222 to the peripheral sprocket rings 234 of the lower drive wheels 242, as shown.
Preferably, each drive wheel 242 comprises a cylindrical hub 244 adjoining two opposing frustoconical side spools, as shown. Preferably, at least one of the two frustoconical side spools comprise sprocket ring 234, as shown. Preferably, a plurality of hose-engaging members 246 project outwardly from hub 244, as shown. Preferably, hose-engaging members 246 are adapted to mechanically manipulate vacuum hose 112 by engaging the circumferentially ridged exterior surface of vacuum hose 112. Preferably, each drive wheel 242 comprises a central axle about which drive wheel 242 rotates. Preferably, upper drive wheels 242 are geared to rotate opposite of lower drive wheels 242, as shown, thus driving vacuum hose 112 (indicated in dash lines) through control assembly 108 in a generally linear manner.
Preferably, each lower drive wheel 242 is mounted within a pivoting armature 248 forming lower articulated drive wheel assembly 330, as shown (and further described in FIG. 24). Preferably, both pivoting armatures 248 rotate about the center axis of secondary wheel drive gear 238, as shown. Preferably, each lower drive wheel 242 is held in operational tension against vacuum hose 112 by a tension spring 250 coupled to each pivoting armature 248, as shown. A manually depressible bar 252 (or similar actuator structure) is used to manually disengage drive wheels 242 from vacuum hose 112, as shown. Preferably, by applying a downward force (indicated by arrow 252A) on each pivoting armature 248, each lower drive wheel 242 is swung away from a position of engagement with vacuum hose 112 (thus allowing removal or repositioning of the hose).
In preferred operation, hydraulic drive turbine 240 is operationally coupled to constant torque spring 141 by clutch assembly 226 of gear train assembly 208. As hydraulic drive turbine 240 operates, drive wheels 242 deploy vacuum hose 112. As vacuum hose 112 is deployed, constant torque spring 141 within constant torque spring housing 140 is simultaneously wound. If vacuum hose 112 is fully deployed before constant torque spring 141 is fully wound, clutch assembly 226 will allow primary wheel drive gear 222 to slip relative to the rotation of shaft 224 until constant torque spring 141 is fully wound. If constant torque spring 141 (at least one spring tensioner) is fully wound before vacuum hose 112 is fully deployed, clutch assembly 226 will allow first spring gear 230 to slip relative to the rotation of shaft 224 until vacuum hose 112 is fully deployed.
When constant torque spring 141 is fully wound and vacuum hose 112 is fully deployed, the system detects the condition (as described in FIG. 14) and switches suction flow from hydraulic drive turbine 240 to vacuum hose 112 and vacuum head 113. Since drive turbine 240 is no longer powered, a gravity actuated ratchet, most preferably a ratchet 253 engaging first gear 214, holds gear train assembly 208, drive wheels 242, and vacuum hose 112 firmly in place during deployment.
When circulation pump 130 (typically the swimming pool filter pump) turns off, start-stop piston 215 is deactivated allowing pivoting gear assembly 212 to disengage hydraulic drive turbine 240 from the balance of the gear train assembly 208, as shown. As this happens, constant torque spring 141 (at least embodying herein wherein such at least one automatic hose retractor comprises at least one spring tensioner adapted to tension at least one retractor spring during deployment of the at least one vacuum hose by such at least one automatic hose deployer) releases its wound up energy through spring drive shaft 236, second spring gear 232, first spring gear 230, clutch assembly 226, primary wheel drive gear 222, and drive wheels 242, as shown. This results in vacuum hose 112 being pulled back into storage tube 111 and vacuum head 113 being drawn back into main housing 120. The above-described arrangements at least embody herein at least one drive assembly comprising at least one first hose-engaging wheel and at least one second hose-engaging wheel each one adapted to physically engage the at least one vacuum hose; wherein, during such physical engagement, the at least one vacuum hose is movably deployed by rotation of such at least one first hose-engaging wheel and such at least one second hose-engaging wheel by such at least one hydraulic motor; and wherein, during such physical engagement, the at least one vacuum hose is movably retracted by counter-rotation of such at least one first hose-engaging wheel and such at least one second hose-engaging wheel by such at least one spring tensioner.
Preferably, constant torque spring housing 140 comprises a waterproof enclosure for containing constant torque spring 141 in a dry condition. At least one shaft seal is used at the penetration of spring drive shaft 236 with constant torque spring housing 140. Preferably, constant torque spring 141 comprises an output spool having a diameter of about four inches and a supply spool having a diameter of at least two inches. Preferably, a 301 stainless steel spring having a length of about 33 inches, a thickness of about 0.02 inches, and a width of about one inch operates between the two spools. Preferably, constant torque spring 141 is designed for an operational life of at least about 4000 cycles, more preferably about 10,000 cycles.
FIG. 14 shows a diagram illustrating the detection and control components of control assembly 108 of FIG. 1. Control assembly 108 preferably comprises four detection and control components identified herein as spring-fully-wound detector 260, hose deployment detector 262 of vacuum transfer assembly 270, turbine drive controller 264, and control valve assembly 136, as shown. In the prior figures, the general operation of control assembly 108 was discussed in specific regard to the mechanical assemblies directly related to the deployment and retraction of vacuum hose 112. In FIG. 14, the operation of and control of the suction water flow is discussed in further detail.
Preferably, turbine drive controller 264 comprises start-stop piston 215 as previously described in FIG. 13. Preferably, start-stop piston 215 is pressure actuated by a vacuum connection originating at primary vacuum chamber 135 of control valve assembly 136, as shown (preferably coupled directly to vacuum pressure originating at connection 134 of FIG. 5). Preferably, piston 215 a of start-stop piston 215 is drawn into the housing of start-stop piston 215 in the presence of suction pressure at primary vacuum chamber 135.
Preferably, control valve assembly 136 (at least embodying herein at least one automatic switch adapted to automatically switch the coupling of the at least one low-pressure fluid source between such at least one hydraulic motor and such at least one fluid coupler) comprises a plurality of pressure actuated, float actuated, and manually actuated valves, as shown. The primary function of control valve assembly 136 is to switch suction water flow between hydraulic drive turbine 240 and vacuum hose 112. A second function of control valve assembly 136 is to provide a means for manual and automatic low water-level retraction of vacuum hose 112 during operation of circulation pump 130.
The principle component enabling the above-described switch of suction water flow between hydraulic drive turbine 240 and vacuum hose 112 is main diverter valve 266, as shown. Preferably, main diverter valve 266 is adapted to control the flow of water entering primary vacuum chamber 135 from vacuum transfer conduit 206 (coupled to hydraulic drive turbine 240) and/or vacuum hose transfer conduit 268, as shown. Note that vacuum hose transfer conduit 268 of control valve assembly 136 extends to transfer assembly 270, as shown.
Preferably, main diverter valve 266 is movably retained within control valve body of control valve assembly 136, as shown. Preferably, main diverter valve 266 comprises two valve gates rigidly coupled along common shaft 273. Preferably, first valve gate 274 opens and closes a passageway between primary vacuum chamber 135 and vacuum transfer conduit 206. Similarly, second valve gate 276 preferably opens and closes a passageway between primary vacuum chamber 135 and vacuum hose transfer conduit 268. Preferably, main diverter valve 266 is configured such that first valve gate 274 fully opens as second valve gate 276 fully closes (and vice versa). This preferred arrangement provides a means to establish water flow alternately between hydraulic drive turbine 240 and vacuum hose 112. Main diverter valve 266 is preferably biased toward a condition whereby first valve gate 274 (controlling water flow from the turbine) is normally open and second valve gate 276 (controlling water flow from vacuum hose 112) is normally closed. Preferably, a helical spring 280, located along an extension of common shaft 273, provides the appropriate biasing force.
Operation of main diverter valve 266 is preferably automatic. Preferably, operation of main diverter valve 266 is controlled by vacuum actuated bellows 247, as shown. Preferably, common shaft 273 of main diverter valve 266 extends through the wall of vacuum transfer conduit 206 and is fixed to the interior of bellows 247, as shown. Preferably, the interior of vacuum actuated bellows 247 is coupled by pressure transfer passage 278 to primary vacuum chamber 135, as shown. During periods when circulation pump 130 is inactive, bellows 247 is held in an expanded configuration by spring 280, as shown. In this condition, first valve gate 274 is open and second valve gate 276 is closed.
