Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. No. 60/892,921 filed 5 Mar. 2007, the entire contents and substance of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a cleaning system and, more particularly, to a cleaning system for treating water and the removal of floating debris for above-ground swimming pools or other above-ground fluid containers. The present invention further relates to an integrated above-ground swimming pool pump-filter-skimmer system, and to an improved side wall-mounted housing and replaceable cartridge filter for such integral systems.
2. Description of Related Art
Cleaning systems for swimming pools are known in the art. Some existing integrated swimming pool cleaning systems include a pump, skimmer, and filter for cleaning the water contained within the pool. Most such cleaning systems for above-ground pools are supported using a ground level base beside the pool wall, due to their heavy weight.
Such designs present a potential safety hazard in use, because cleaning systems are often misused as a step for pool entry or exit, particularly by children. In addition to safety risks, use of the cleaning system housing for ingress and egress places a significant physical strain on the mounting and plumbing connections, and can lead to functional leaks or failures. Moreover, existing integrated swimming pool cleaning systems for above-ground pools are applicable only for use on rigid wall pool designs with straight vertical side walls.
An exemplary conventional cleaning system is shown in FIG. 1A. A conventional cleaning system 20, which is fully supported by a base 10, is in communication with the above-ground pool 100.
What is needed, therefore, is an improved cleaning system for above-ground pools, wherein the cleaning system is fully supported by the pool, and there is no need for a base. It is to such a device that the present invention is primarily directed.

BRIEF SUMMARY OF THE INVENTION

Briefly described, in preferred form, the present invention relates to an above-ground swimming pool having a base, a side wall, and a portion of a cleaning system. The portion of the cleaning system for cleaning the water of the above-ground swimming pool is fully supportable upon the side wall. Specifically, the cleaning system for cleaning water of the above-ground swimming pool is solely supported by the side wall. The cleaning system can include various portions, including a housing, a filter assembly, a skimmer assembly, and a pump assembly.
The cleaning system cleans water in the pool. Specifically, the pump assembly can draw water from the pool into the housing. The water drawn from the pool can contain debris. Larger debris is captured by the skimmer assembly, while debris not captured by the skimmer assembly is filtered by the filter assembly. The pump assembly can then pump the clean water back into the pool via a return line.
In one embodiment, the present invention relates to an above-ground container capable of holding a fluid, and comprises a base; at least one side wall in communication with the base; and a cleaning system solely supported by a portion of the side wall. The cleaning system can include a housing defining a hollow cavity, wherein the housing is fully supported by the side wall of the above-ground container, such that no portion of the cleaning system is supported by a ground surface upon which the base is supported. Further, a filter assembly of the cleaning system can be disposed within the hollow cavity of the housing. The filter assembly is adapted to filter debris in the fluid of the above-ground container. Moreover, a skimmer assembly of the cleaning system disposed within the hollow cavity of the housing. The skimmer assembly is adapted to gather debris off a top surface of fluid of the above-ground container. In addition, a pump assembly of the cleaning system can be removably secured to a first end of the housing. The pump assembly is adapted to control the filter assembly and the skimmer assembly. The pump assembly can be further adapted to extract and/or circulate fluid and debris of the above-ground container to be filtered by the filter assembly and be gathered by the skimmer assembly. A return line is coupled to the side wall of the above-ground container and the pump assembly can permit fluid extracted from the above-ground container to be inserted into the above-ground container.

In addition to the definitions of terms provided below, it is to be understood that as used in the specification and in the claims, “a” or “an” can mean one or more, depending upon the context in which it is used.
As used herein, the term “pool” shall refer to and include any above ground or free-standing swimming pool, spa, water tank, or other above-ground liquid containment enclosure.
Embodiments of the present invention are directed towards devices combining swimming pool filters, skimmers, and pumps into integral, sidewall-mounted systems for above-ground pools, and methods for the use of such systems to remove both larger floating debris and smaller particulate matter to maintain water clarity and hygienic safety within said pools.
To facilitate an understanding of the principles and features of the invention, it is explained hereinafter with reference to its implementation in an illustrative embodiment. In particular, the invention is described in the context of being a cleaning system for an above-ground swimming pool. Because of its light weight, the cleaning system can be solely supported by a side wall of the container.
The invention, however, is not limited to its use as a cleaning system for an above-ground swimming pool. Rather, the invention can be used to clean many different above-ground containers capable of holding a fluid that is needed or desired. Thus, the cleaning system for filtering and skimming the water in a swimming pool described herein after can also find utility as a cleaning system for a cleaning a variety of fluids contained in various above-ground containers.
The material described hereinafter as making up the various elements of the container of the invention are intended to be illustrative and not restrictive. Many suitable materials that would perform the same or a similar function as the materials described herein are intended to be embraced within the scope of the invention. Such other materials not described herein can include, but are not limited to, materials that are developed after the time of the development of the invention, for example.
An environment of the present invention is illustrated in FIG. 1B. An above-ground pool 100 can solely support a cleaning system 200 for cleaning the water in the pool. Specifically, a base is not needed to support the cleaning system 200; rather, a side wall of the pool is adapted to fully support the cleaning system 200.

Above-Ground Swimming Pools

Referring now to the drawings, wherein like reference numerals represent like parts throughout, the cleaning system is securable and supported by a container, or portable swimming pool, constructed in accordance with the following description. Four different containers can be seen in the perspective views illustrated in FIGS. 2A-2D. As shown in FIGS. 2A-2D, an above-ground swimming pool 100 has a base 110 and a side wall 120, which is made from a physical material and is formed in a particular shape.
The pool 100 can be a frame pool or a pop-up type of pool, both of which being collapsible in nature. First, the frame pool is typically pre-fabricated and includes a plurality of external vertical braces or frames for supporting the frame pool above the ground (see FIGS. 2A and 2B). The frame pool can be made of metal, plastic, and the like. Second, the pop-up pool is adapted to rise with the amount of water inserted into pool (see FIG. 2C), and can also be outfitted with external braces or frames for additional support (see FIG. 2D). As one skilled in the art would appreciate, other types of pools can be used with the present invention.
The shape of the pool 100 can be circular, oval, and the like. The pool 100 can be made in a variety of shapes, including, but not limited to, rectangular, square, oblong, oval-shaped, elliptical, rectangular with rounded corners, and the like. Thus, it will be apparent to one skilled in the art that the configuration of the pool 100 can be many shapes. Different shapes can result in the pool 100 having more than one side wall 120 forming the perimeter of the pool 100. Additionally, the pool 100 can be made in a variety of sizes, depending upon the desired use.
The pool 100 is formed with the base 110 and side wall 120. The base 110 and side wall 120 can be manufactured out of many different materials and can be formed of the same materials or each a different material. For example, the base 110 and side wall 120 of the swimming pool 100 can be formed from a textile (e.g., burlap, etc.) or synthetic material (e.g., plastics, polyurethane, PVC, nylon, etc). Many materials (especially water-permeable textiles, etc.) can be used to construct a pool; the materials, however, should be treated to retain water. For example, such materials could be adhered to, laminated with, coated with, or bonded to a material impermeable to water. In accordance with a preferred embodiment, the base 110 can be formed from a nylon shell, which can be laminated or otherwise treated to hold water. For example, the nylon shell might be bonded to another material, such as polyurethane, PVC, vinyl, or other suitable impermeable lining to provide the desirable waterproof qualities, and to provide a more pleasing tactile quality to the interior of the pool 100. Similarly, the wall 120 of the pool 100 can be constructed from these materials, or other materials having similar suitable qualities. Many of the materials that are used can be selected for their durability.
For example, the base 110 can be formed from materials that can be more durable than the side wall 120, as this section of the pool 100 would likely be subjected to more wear than that experienced by the side wall 120. Also, as described, the base 110 and side wall 120 can be formed from a combination of materials, which can be adhered or bonded together. The materials used for the various portions of the pool 100, including, for example, the base 110 and the side wall 120, can be joined by way of a number of commonly known suitable techniques, such as sewing, adhesives, bonding, lamination, RF welding, other suitable joining techniques, and the like. The connection of the base 110 to the side wall 120 can be along the bottom 122 of the side wall 120. The base 110 includes a perimeter, wherein the side wall 120 can be connected about the perimeter of the base 110.
The side wall 120 can include an inner wall 126 and an outer wall 128. The inner wall 126 is sealable to the outer wall 128. The side wall 120 is preferably non-inflatable. Further, the side wall 120 is preferably non-spring activated.
In one embodiment, the inner wall 126 can be made of pliable plastic, while the outer wall 128 is made of hard plastic. Then, inner wall 126 can limit leakage of fluid should the outer wall 128 crack. Likewise, the material of the inner wall 126 can be made of hard plastic, and the material of the outer wall 128 can be made of pliable material to protect from potential leakage should the hard plastic crack.
In another embodiment, the inner wall 126 can be made of hard plastic, while the outer wall 128 can also be made of hard plastic.
The pool 100, as illustrated in FIGS. 2C-2D, can further include a floatation device 130, which is formed in the shape of the pool 100, attached to the top 124 of the side wall 120. According to an exemplary embodiment shown in FIGS. 2C-2D, the floatation device 130 can be an inflatable ring 132. This inflatable ring 132, when inflated, can provide some stiffness at the top 124 of the side wall 120, and can help maintain the overall shape of the pool 100. Moreover, the inflatable ring 132 can provide padding for those entering and exiting the pool 100, and can also provide a manner by which the pool 100 changes from a collapsed to an expanded configuration with the addition of water within the pool 100. Additionally, as the floatation device 130 can be buoyant, it can be made to rise with the level of water within the pool 100, such that as water is deposited in the pool 100 and the floatation device 130 rises with the level of that water, the side wall 120 is automatically erected as the pool 100 is filled.
The floatation device 130 can be made from a variety of materials. For example, the floatation device 130 can be a standard inflatable polyurethane casing, or similar casing that is suitable for retaining air or other gas in an inflated state. Additionally, the floatation device 130 can make use of a variety of chemical or other reactions that would automatically inflate it. The floatation device 130 can be inflated by conventional means, for example by a valve configured for oral inflation or for inflation by a device such as a pump, and the like.
The floatation device 130 can also be made from material that does not require inflation, but provides adequate buoyancy and floats on the water contained within the pool 100 (or other fluid when the pool is used as a general container). For example, special foams, polystyrene, or other materials can be used to create a floatation device 130, which would float with the water line contained in the pool 100, and cause the walls 120 to be erected as the pool 100 fills. In this manner, the pool 100 can automatically change from a collapsed to an expanded configuration. As the pool 100 is a collapsible pool, and adapted to be folded, the floatation device 130 can be made of a material that can be subjected to folding, without becoming damaged. Those skilled in the art will appreciate that, although some potential materials from which the floatation device 130 can be formed have been mentioned above, other materials including, but not limited to, newly developed materials can be incorporated within the design of the invention, and used to form the floatation device 130 without departing from the invention.
It will be appreciated by those skilled in the art that the floatation device 130 can be of a nature other than an inflatable ring. For example, this floatation device 130 can be made of a material that floats, and is bendable, such that it can be folded or bent.
The pool 100 can be conveniently collapsed for storage and/or transport by deflating the inflatable ring 132 and folding onto itself along with the base 110 and side wall 120 material in a manner that is well known.
Additionally, as illustrated in FIG. 2C, the pool 100 can comprise a porthole 150, or a plurality thereof. The portholes 150 are translucent sections of the side wall 120, either integrally formed in/with the side wall 120, or separate elements. The portholes 150 are adapted like a window permitting one to see into the pool 100. Similarly, the portholes 150 enable one within the pool to see outside the pool 100. The portholes 150 can further enable determining the level of fluid within the pool 100.
The portholes 150 can be of a particular shape. For instance, the shape of the portholes 150 can be oval. Alternatively, the shape of the portholes 150 can be round or circular. As will, however, be apparent to one skilled in the art, the configuration of the porthole 150 can be many shapes. In a preferred embodiment, the locations of the portholes 150 can be placed symmetrically about the side wall.
The portholes 150 can aid in safety, as the portholes 150 can enable viewing into the pool 100 through the side wall 120. If the portholes 150 are removably designed by suitable means, the porthole 150 can also be used as a drainage device, enabling quick emptying of the fluid of the pool 100. The portholes 150 can be integrally formed during manufacturing of the side wall 120, or removable, wherein they are attached via a waterproof/leak resistant means. The portholes 150 can also be included via a non-removable method, wherein the portholes are secured within the side wall 120.
The portholes 150 can be secured in different ways within the side wall 120. In one embodiment, the portholes 150 can be flush with the side wall 120, such as enabling a drainage device. In another embodiment, the portholes 150 can be insertable between the inner wall 126 and the outer wall 128 of the side wall 120. Preferably, the portholes 150 are sealed between the inner wall 126 and the outer wall 128, wherein there is a hole between the inner wall 126 and the out wall 128, whereby the porthole seals the hole. The porthole 150, thus, can be sandwiched between the inner wall 126 and the outer wall 128. The porthole 150 can be sealed by conventional compression or heat sealed methods.
FIGS. 2A, 2B and 2D also illustrate the pool 100 having a one or more braces or structural support members 160. The support member 160 can include vertical rib supports, and can be coupled proximate to the side wall 120 of the pool 100. For example, the support member 160 can be inserted within the material making up the side wall 120. The support member 160 can comprise at least a portion of the floatation device 130, and can have at least a portion coupled to the top of the side wall 120 and vertically along the side wall 120 to provide buoyancy and/or rigidity to the side wall 120. The support member 160 can comprise, for example, one or more inflatable bladders, collapsible foam, removable support members, or the like.
One skilled in the art would appreciate that the support members 160 can be used on a frame pool, as well as a pop-up pool for supporting the pool above the ground. In an exemplary embodiment, the support member 160 are positioned outside the pool 100.
The pool 100 can include a ladder (not shown) to enable one to enter and/or exit the pool 100. The ladder can be integral with the support member 160, or not. The ladder can further be insertable into the pool 100, enabling one to exit the pool 100. Because a rim of the pool 100 is above the ground, the ladder is preferably flush with the rim for easy entry/exit from the pool 100.
Because the pool 100 is collapsible, the fluid in the pool 100 should be drainable. Preferably, a drainage assembly 180, as illustrated in FIG. 2D, is integral with the pool 100. In an exemplary embodiment, the drainage assembly 180 is a cork or like device, that is removeable from the pool 100, such that, when removed the water from the pool 100 can be drained. The drainage assembly 180 can also be a valve enabling control of draining the pool 100. One skilled in the art would appreciate that the drainage assembly 180 can be many devices enabling easy draining of the pool 100, safely and environmentally.
From the foregoing, it can be seen that the above-ground container provides a number of different collapsible containers, which can be used as swimming pool. The various embodiments described above provide collapsible swimming pool that are foldable, enable easy storage, and increase portability when compared with prior approaches. Additionally, according to various embodiments, the collapsible swimming pool can be provided with a pop-up mechanism that automatically erects the pool to its full-sized, expanded configuration. The swimming pool can be constructed from durable, lightweight, foldable materials which are not easily damaged, and therefore contribute to their long life.

Cleaning System

Generally, and as illustrated in FIG. 3, the present invention is a cleaning system for cleaning the fluid of debris in the above-ground container. More specifically, the present invention is a cleaning system for cleaning, filtering, and skimming the water in an above-ground swimming pool. The cleaning system is lightweight enough such that the side wall of the above-ground swimming pool can support the entire system. As a result, a ground level base beside the pool wall is not needed.
FIG. 3 is a perspective view of the cleaning system 200. The cleaning system 200 is capable of removing debris from the above-ground container or swimming pool 100.
The cleaning system can comprise a housing, a filter assembly, a skimmer assembly, a pump assembly, and a return line. The housing defines a hollow cavity, and is supported by the side wall of the above-ground container. The filter assembly is disposed within the hollow cavity, and is adapted to filter debris in the fluid of the above-ground container. The skimmer assembly is also disposed within the hollow cavity, and is adapted to gather debris off a top surface of fluid contained within the above-ground container. The pump assembly is removably securable to a first end of the housing, and is adapted to control the filter assembly and the skimmer assembly. The pump assembly is further adapted to extract fluid and debris from the above-ground container to be filtered by the filter assembly and be gathered by the skimmer assembly. The return line is coupled to the side wall as well as the pump assembly, and is adapted to permit fluid extracted from the above-ground container to be inserted into the above-ground container.
The housing is supported to the side wall of the above-ground container by an attachment assembly. Preferably, the housing is connected to the above-ground container by gaskets, such that no element penetrates the side wall. The return line is coupled to the side wall via a return line pool connector assembly.
FIG. 3 illustrates the cleaning system 200 comprising housing 205 and the pump assembly 300. The housing 205 defines a hollow cavity 210 for housing the filter assembly 400 (see FIG. 4) and skimmer assembly 500 (see FIG. 4).
The housing 205 includes a bottom portion 215 and a top portion 220. The pump assembly 300 is preferably coupled to the bottom portion 215 of the housing 205. While the exemplary housing that is illustrated the figures is generally cylindrical, housings in various embodiments of the present invention can take many shapes, for example and not limitation, rectangular, rounded, non-rounded, polygonal, and the like.
Referring now to FIG. 4, an exploded view of the cleaning system 200 is illustrated. As mentioned, the cleaning system 200 includes a housing 205, a pump assembly 300 coupled to the bottom 215 of the housing 205, a filter assembly 400, and a skimmer assembly 500. FIG. 4 also shows the attachment assembly 600 by which the cleaning system 200 is secured to the pool 100, and the return line pool connection assembly 700, by which the return line 350 is coupled to the side wall 120.
The top portion 220 of the housing 205 can be configured to receive a lock top 225, which can be received by threads, locking detents, or other securely engaging retaining means within said housing top portion 220, preferably at the top end 220 t. The lock top 225 can be removable, enabling access into the hollow cavity 210.
The filter assembly 400 and skimmer assembly 500 can be disposed in the defined hollow cavity 210 of the housing 205.
The filter assembly 400 positioned within the housing 205 can include a removable filter cartridge 405. The filter cartridge 405 can be sized and provided to filter water-borne particulate matter, for example and not limitation, debris too small to be first retained by the skimmer assembly 500.
The skimmer assembly 500 is preferably positioned above the filter assembly, and first catches the debris. Specifically, adjacent to the housing top end 220 t, a skimmer port 505 can be in open fluid communication with the interior of the housing 205. A removable strainer basket 510 is provided to be retained within the housing 205. Preferably, the strainer basket 510 is positioned below water level 170 of the pool 100, such that water entering the housing 205 through the skimmer port 505 first drains through the removable strainer basket 510.
The filter assembly 400 and the skimmer assembly 500 are controlled by the pump assembly 300. Preferably, the pump assembly 300 is positioned at the bottom end 215 b of the housing 205. The bottom end 215 b includes an aperture 230 which is sized and situated to directly connect with the pump assembly 300.
The pump assembly 300 includes a pump 305 without the need for intervening pipes or other intervening connections. The pump 305 includes a pump inlet 310 and a pump outlet 315, and can be secured to the housing 205 by a pump retainer 235. As shown in both FIGS. 4 and 7, the retainer 235 can be received into threads, locking detents, or other securely engaging retaining means on the inlet 310 of the pump 305. In addition, an optional O-ring 320 or other washer or gasket can be interposed between said pump inlet 310 and the pump retainer 235 ensuring a watertight connection therebetween. Similarly, an O-ring 320 or other washer or gasket can be interposed between the pump outlet 315 and a return hose 350. The pump inlet 310 and the return hose 350 can be connected by a hose clamp 355 or other connector to ensure a watertight connection therebetween.
Still referring to FIG. 4, the return hose 350 can extend a desired distance away from the housing 205 to allow adequate separation between the water intake through the skimmer assembly 500 and a connection assembly 700, or more specifically a fitting 705 of the connection assembly 700. The return hose 350 connects to the return pool wall fitting 705 through a series of watertight connections.
For example, as shown in the exemplary embodiment of the present invention in FIGS. 3-4 and 9-10, the return hose 350 can connect to an elbow fitting 710 using an interposed O-ring 320 or other washer or gasket and a hose clamp 355 or other connector to ensure a watertight connection therebetween. The elbow fitting 710 can connect the return pool wall fitting 705 through a return aperture 715 in the side wall 120 of the pool 100. A watertight connection between the elbow fitting 710 and the return pool wall fitting 705 can be achieved using a pipe nut 720 and a thrust washer 725 on the outer side wall 120 of the pool 100. Furthermore, a gasket 730 between the return pool wall fitting 705 and the inner side wall 120 of the pool 100. The return pool wall fitting 705 can be fitted with a diverter fitting 735 secured by a locking ring 740 to divert return water flow away from the skimmer port 505.
Referring back to the skimmer port 505, it can be attached to the side wall 120 of the pool 100 through the aperture 190 (see FIG. 2C). The attachment assembly 600 includes an outer skimmer gasket 605 that can be positioned between the outer surface of the side wall 120 of the pool 100 and an inner gasket 610 and a skimmer face plate 615 on the inner side wall 120 of the pool 100. The skimmer port 505 can be attached flush to the outer skimmer gasket 605. The skimmer face plate 615 can also be flush to the inner gasket 610, without the need of a flange, lip, or other projection of the skimmer port 605 or skimmer face plate 615 extending through the sidewall 120 of the pool 100. The skimmer port 505, outer skimmer gasket 605, inner gasket 610, and skimmer face plate 615 can be attached through the side wall 120 using a plurality of securing mechanisms 620, such as screws or other fasteners to achieve a watertight connection between the skimmer port 505 and the skimmer face plate 615.
As shown in FIGS. 4 and 8, in various exemplary embodiments of the present invention, the connection of the skimmer port 505 to the skimmer face plate 615 as shown above through the side wall 120 of an above-ground pool 100 can suffice as the only needed physical support to mount and maintain the entire cleaning system. In some embodiments of the present invention and as shown in FIG. 3, the housing 205 can further be provided with a stabilizing foot 240 that can rest against or be attached to the outer surface of the side wall 120. In other embodiments of the present invention not shown in the figures, additional support connections can be employed between the housing 205 and the vertical and/or horizontal frame elements that support the liner of an above-ground pool 100.
The skimmer face plate 615 is shown in FIGS. 4 and 8 to be provided with a weir 625. The weir 625 is pivotally attached to the skimmer face plate 615 in such a manner to restrict movement of the weir 625, such that water flow can be admitted through the skimmer port 505, but the weir 625 is close enough against the skimmer face plate 615 to restrict water egress through the skimmer port 505. The weir 625 can further be provided with one or more weir foam elements 630 to assist the weir 625 in restricting water flow when the pump assembly 300 is not operating.
In operation, in the exemplary embodiment shown in FIG. 4, the pump 305 of the pump assembly 300 can draw water from the pool 100 by the weir 625 into the skimmer port 505. Large particulate matter suspended in the water is collected by the strainer basket 510. The filter cartridge 405 can be provided with a space to contain chlorine tablets or other chemical delivery devices to maintain a desired antimicrobial chemical level within the water. Smaller particulate matter within the pool water not removed by the skimmer basket 510 is then removed by the filter cartridge 405 as the water is drawn through the hollow cavity 210 of the housing 205 and into the pump inlet 310. Water flow then exits the pump 305 through the pump outlet 315, and enters the return hose 350 to return to the pool 100 through the pool wall fitting 705.
Access for emptying the strainer basket 510 and replacement of the filter cartridge 405 is achieved through removal of the lock top 225 by a user, whereupon the strainer basket 510 and the filter cartridge 405 can be readily removed from the housing 205 and replaced as desired or needed.
As shown in FIGS. 4 and 8, if desired, a user can connect a pool vacuum connector 245 which is sized and configured to fit through the weir 625 and skimmer port 505 to sealably fit atop the strainer basket 510 within housing 205 below water level 170. Embodiments of such a pool vacuum connector 245 according to the present invention can be provided with a connector for a vacuum hose connecting to a vacuum device (not shown). In such embodiments, when the pool vacuum connector 245 is attached, negative water pressure from the pump assembly 300 can be used to power a pool vacuum device to remove debris on the bottom of the pool (e.g., sitting on the base 110), with debris collected by the strainer basket 510 and removable filter cartridge 405.
In use, the pump assembly 300 can be controlled by an electrical timer or other electrical or electronic control means (not shown) to allow intermittent or continuous pump operation as desired by a user.
In essence, the cleaning system is adapted to remove debris via the skimmer assembly and the filter assembly, by pulling water into the housing via the pump assembly. The cleaning assembly is lightweight enough to be fully supported by the side wall of the pool, such that a base or other mechanism is not needed to properly position the cleaning system.

Pump Assembly

FIG. 5 illustrates an exploded view of the pump assembly 300. As noted, the pump assembly 300 is adapted to control the operation of the cleaning system 200. Specifically, the pump assembly 300 can pull fluid, typically water, from the above-ground container, preferably the above-ground swimming pool, to be skimmed by the skimmer assembly 500, and then filtered by the filter assembly 400.
The pump assembly 300 includes the pump 305, which is the device that pulls the fluid towards, and ultimately into, the housing 205. The pump assembly includes a pump body 325 to contain the pump 305. A rotor assembly 800 (shown in more detail in FIG. 6, and described more below) can be coupled to the pump body 325. A pump gasket 330 is positioned atop the top portion 325 t of the pump body. A volute housing 335 provides the pump inlet 310 and pump outlet 315 for fluid to enter/exit the pump assembly 300.
Preferably, the volute housing 335, pump gasket 330 and rotor assembly 800 are secured to the top portion 325 t of the pump body 325 with securing members 340, such as screws, bolts, and the like.

Rotor Assembly

Referring now to FIG. 6, the rotor assembly 800 of the pump assembly 300 is illustrated in a perspective view. The rotor assembly 800 includes an elongated shaft 805 having a first end 807 and a second end 809. The shaft 805 can be received by the axle 810, and connected the impeller 815 via an end cap 820 and washer 825 at the shaft's first end 807. The axle 810 is preferably magnetic. At the both ends 807 and 809 of the shaft 805 are positioned with an end cap 820 and washer 825.
The pump assembly 300 is adapted to rotate the rotor assembly. Specifically, the pump 305 rotates the shaft 805, which rotates the impeller 815. Together with the pump assembly 300, the rotor assembly 800 enables water to be pulled into the housing 205 of the cleaning system.

Method of Installation

The present invention includes a method of installing the cleaning system 200. Preferably, the cleaning system 200 can be secured to the swimming pool 100, and does not need the assistance of a separate base to be supported.
Due to risk of electrical shock, it is preferred that the cleaning system 200 be connected to a grounding type receptacle protected by a ground fault circuit interrupter (GFCI). The receptacle is preferably at least ten feet away from the pool 100.
To install the cleaning system, the lock top 225, strainer basket 510, and filter cartridge 405 can be first be removed from the housing 205. Then, the O-ring 320 for the pump assembly 300 can then be lubricated, preferably with petroleum jelly.
Subsequently, the pump assembly 300 can be connected to the bottom portion 215 of the housing 205. The pump assembly 300 is preferably connected, such that the volute housing 335 extends out to a side of the housing 205, as illustrated in FIG. 7. The pump assembly 300 can be inserted until it bottoms out, and the ribs on the volute housing 335 insert into two slots on the bottom of the housing 205. The retainer 235 can be then be tightened to the volute housing 335, specifically to the pump inlet 310.
Installation continues by locating the mounting location for the cleaning system 200 on the side wall 120 of the pool 100. The inner gasket 610 and the face plate 615 are installed on the inner side wall 126 (inside the pool 100) by securing mechanisms, preferably screws and the like, as shown in FIG. 4. The outer skimmer gasket 605 can be secured to the outer side wall 128 (outside the pool 100), and secured also by securing mechanisms. The housing 205 can be coupled to the outer skimmer gasket 605.
The connection assembly 700 for the return line can be installed. The gasket 730 can be lubricated, and then installed over the threads of the return pool wall fitting 705. The return pool wall fitting 705 can be inserted through an aperture 715 of the side wall 120. A thrust washer 725 can be placed over the return pool wall fitting 705, and then a pipe nut 720 can be threaded until the return pool wall fitting 705 is hand tight. It is preferable that the return pool wall fitting 705 not be over tightened, as this can cause wrinkles in the side wall, which could ultimately compromise the integrity of the side wall 120. Next, tape, such as Teflon® tape, can be applied to the thread of the elbow fitting 710, and it can be installed to the return pool wall fitting 705.
Next, the return hose 350 can be secured to the pump assembly 300 and the return connection assembly 700. As shown in FIG. 9, the return hose 350 has a first end 352 connected to the pump assembly 300, and a second end 354 connected to the connection assembly 700.
The first end 352 of the return hose 350 is connected to the pump assembly 300 by a hose clamp 355. The hose clamp 355 can first be loosened before sliding it over the first end of the return hose 350. It is preferable to lubricate the O-rings 320 on the volute housing 335, and on the elbow fitting 710 before installing the O-ring 320 on the return hose 350. Specifically, the first end 352 of the return hose 350 can be connected to the volute housing 335 of the pump assembly 300. The second end 354 of the return hose 350 can be connected to the elbow fitting 710 of the connection assembly 700. Both of the hose clamps 355 can then be tightened.
The filter assembly 400 and skimmer assembly 500, including the filter cartridge 405 and the strainer basket 510, can be re-inserted back into the housing 205. The filter cartridge 405 can slip over the retainer 235, and preferably seals at the bottom of the housing 205. Accordingly, the strainer basket 510 can then sit in a groove in the hollow cavity 210 of the housing 205. The lock top 225 can then be twisted back into place until locked.
The weir foam element 630 can be inserted into the weir 625, and under weir tabs to secure the weir foam element 630 in place. The weir 625 can be slid into grooves inside the pool 100, and once inside can be flipped over to be locked into place. The weir 625 can be pushed in the grooves, as shown by Arrow #1 of FIG. 8. After the pool 100 is filled with water, it is preferable that all hose connections and fittings are checked to ensure that there is no leakage.

Method of Cleaning Filter Assembly

The present invention also includes a method of cleaning the filter assembly 400.
Before cleaning the filter assembly 400, power to the cleaning system 200 should be turned off. Also, the strainer basket 510 and the filter cartridge 405 can be removed from the housing 205.
The filter cartridge 405 can be cleansed of coarse direct and debris by pressure washing, ensuring that between the pleats of the cartridge are washed. It has been found that fine particles are more easily removed from the pleats when the cartridge 405 is dry. Therefore, it is preferable that after pressure washing the cartridge 405 it should be allowed to dry and then carefully brushed. The pleats, however, should not be scrubbed. Cleaning or scrubbing the filter cartridge 405, specifically the pleats, too vigorously will wear it much faster than simply hosing it off.
Suntan oils, body oils, algae, and the like can form a coat of film on the pleats of the filter cartridge 405, which oftentimes can not be thoroughly removed by pressure washing. Such films of oils and/or algae can quickly clog the filter's pores, and thus greatly reduce filtration. Therefore, it is preferable to remove such materials from the filter cartridge as soon as possible.
To remove oils, it is preferable to soak the cartridge in a solution of one pound of tri-sodium phosphate (or other strong detergent) to five gallons of water for up to twelve hours. Tri-sodium phosphate is a commonly available detergent solution. After the oils have been removed, it is preferable to rinse the cartridge to remove remaining dirt.
If, however, algae are a problem, it is preferable to add half a pint of pool chlorine or one pint of liquid household bleach to the above cleaning solutions one hour before removing the filter cartridge from the solution. Then, thoroughly rinsing the filter cartridge is recommended before replacing the cartridge.

Method of Diverter Fitting Use

The present invention further provides a method of the using of a diverter fitting in the pool. Using a diverter fitting 735 can divert the direction of return water entering the pool 100. The diverter fitting 735 can be adjusted by loosening the locking ring 740. Then, the diverter fitting 735 can be used to generate clockwise rotation of pool water toward the skimmer assembly 500.
To do so, slightly tighten the locking ring 740 and rotate the diverter fitting 735 upwardly to cause water horizontally under the water surface to point away from the housing 205, or more specifically the skimmer intake area. It is preferable that the diverter fitting 735 not be pointed directly toward the skimmer intake area, as this will decrease the skimming and filtration, because water is not being forced about the pool 100. The locking ring 740 can then be tightened once the desired position of the diverter fitting 735 is determined. The diverter fitting 735 can be positioned downwardly—towards the base 110 of the pool 100—to assist in keeping settlement from building along the bottom of the pool 100.

Method of Vacuum Adapter Use

The present invention also provides a method of using a vacuum adapter with the cleaning system 200. The cleaning system 200 is adapted to receive a vacuum adapter or pool vacuum connector 245, enabling vacuuming of the bottom surface, or base 110, and/or the side wall 120 of the pool 100.
The pool vacuum connector 245 is adapted to be coupled to a pool vacuum (not shown), which can be in communication with a pool handle (not shown), as well as a vacuum hose (not shown).
To install the pool vacuum connector 245, the pump assembly 300 should be initially turned off. The weir 625 can be removed.
The pool vacuum can be connected to its handle, and the lowered into the pool 100. The vacuum hose, which may float, is connected to the pool vacuum at a first end, and the second end, which is loose, can be positioned near the diverter fitting 735. The pump assembly 300 can be turned on, and then by placing the second end of the vacuum hose up to the diverter fitting 735 enables water to fill the hose, which will cause the hose to sink.
Now that the vacuum hose is filled, the pump assembly 300 can again be turned off, and the pool vacuum connector 245 can be slid into the skimmer opening, and the vacuum hose can be connected to the pool vacuum connector 245.
By restarting the pump assembly 300, the pool vacuum will begin to pull debris and other particulates through the vacuum. The user can now vacuum along the desired section of the pool An environment of the present invention is illustrated in FIG. 1B. An above-ground pool 100 can solely support a cleaning system 200 for cleaning the water in the pool 100.
The vacuum hose should not be used alone, that is without the pool vacuum, as liner damage, to the bottom of the pool, can occur. Also, it is preferred that one not vacuum with the strainer basket 510 or with the filter cartridge 405 removed, as pump blockage and/or damage can occur. Further, it is preferred that the vacuum hose not be left hanging out of the pool, as a siphon can occur draining the pool.
When vacuuming is complete, the pump assembly 300, should again be turned off. The pool vacuum connector 245 can be slid out of the hollow cavity 210 and the weir 625 can be reinstalled. The vacuum hose and pool vacuum can then be drained.
Due to the amount of debris gathered, it is recommended that the strainer basket 510 and filter cartridge 405 be removed and cleaned.
