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.
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.

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.

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, vacuum hose 112 is stored in a substantially linear configuration within storage tube 111, as shown.
Preferably, storage tube 111 (at least embodying herein at least one tubular sleeve adapted to removably store at least one substantial portion of the at least one vacuum hose) extents outwardly from swimming pool 102 in a linear or near-linear configuration most accomodating to the physical arrangements of the site.

Preferably, storage tube 111 extents underground from aperture connection 123 of housing 120 (at least embodying herein at least one second passage adapted to provide fluid communication between such at least one hollow interior and such at least one tubular sleeve) at a substantially constant elevation, as shown. Preferably, the interior of storage tube 111 is in fluid communication with the interior of housing 120 and therefore contains a continuous supply of the water of swimming pool 102 (at least embodying herein wherein such at least one tubular sleeve comprises at least one first open end in fluid communication with the at least one pool of water).

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.

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 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.
