Definitions
- the present invention relates to the field of fluid reservoirs, such as swimming pools. More specifically, the present invention relates to an apparatus for cleaning contaminants from the bottom of such reservoirs.
- a leaf skimmer In swimming pools, a leaf skimmer is typically utilized to skim off leaves and other such contaminants that float on the surface and that are pulled into the skimmer by the currents of the recirculating water in the pool. Unfortunately, some debris often sinks to the bottom before it has an opportunity to be caught in the skimmer. In reservoirs, such as ponds, decorative pools, fountains and so forth that do not have a skimmer in them, contaminants blown in or dropped in the reservoirs ultimately sink to the bottom of the reservoir. Contaminants that accumulate on the bottom of a pool are unsightly. Moreover, such contaminants also accelerate the formation and growth of algae, and as the contaminants decompose, the water can become cloudy.
- filter system bypass vacuums to differentiate them from the pool vacuums, discussed above, that are coupled to the water intake of a recirculating water supply for a pool.
- filter system bypass vacuums use the addition of water into the pool to effect their operation. More specifically, water under pressure is supplied to the pool through a hose to force a stream of water through nozzles in the filter system bypass vacuum that are directed toward a debris pickup bag. The high pressure water creates a vacuum to suck up debris from the bottom of a pool.
- Reservoirs such as swimming pools, ponds, decorative pools, fountains, and so forth, can collect large amounts of leaves, rocks, dirt, and other contaminants through severe intentional or unintentional neglect. Additionally, large quantities of contaminants can rapidly collect in the bottom of a reservoir during a severe rainstorm and/or dust storm.
- a filter system bypass vacuum may satisfactorily suck up small amounts of debris, or lightweight debris, such as leaves, grass, and so forth, such a vacuum cannot effectively pick up the large quantities of contaminants found in a neglected or storm ravaged pool. That is, the filter system bypass vacuums tend to generate insufficient suction to pick up large quantities of contaminants and/or heavy contaminants, such as rocks. In addition, tiny particulates, such as dust, may be sucked up by the filter system bypass vacuum only to be released back into the pool through the filter bag of the vacuum. If the filter system bypass vacuum is able to pick up the contaminants, the filter bag of a filter system bypass vacuum rapidly fills with debris, thus necessitating frequent and inconvenient cleaning.
- Another advantage of the present invention is that a vacuum apparatus is provided that effectively removes contaminants in a severely soiled pool.
- Another advantage of the present invention is that a vacuum apparatus is provided that removes contaminants from the submerged surface of a reservoir while producing minimal kick.
- Yet another advantage of the present invention is that a vacuum apparatus is provided that is of simple construction and is easy to use.
- the above and other advantages of the present invention are carried out in one form by a vacuum apparatus for removing contaminants from a submerged surface of a reservoir.
- the vacuum apparatus includes an inlet section having a first inlet end and a second inlet end.
- An intermediate chamber has a first chamber end and a second chamber end, the first chamber end being in fluid communication with the second inlet end.
- the intermediate chamber exhibits a first inner diameter.
- An outlet section has a first outlet end in fluid communication with the second chamber end.
- the outlet section exhibits a second inner diameter that is less than the first inner diameter.
- a fluid supply pipe resides inside the intermediate chamber and has a fluid port directed toward the outlet section. The fluid supply pipe supplies fresh fluid under pressure from the fluid port toward the outlet section to induce a flow of fluid and the contaminants from the reservoir into the first inlet end of the inlet section and through the intermediate chamber and the outlet section.

Abstract
A vacuum apparatus (20) includes an intermediate chamber (30) interposed between inlet and outlet sections (28, 32). A fluid supply pipe (46) resides inside the intermediate chamber (30) and supplies fluid (62) under pressure toward the outlet section (32). An inner diameter (96) the outlet section (32) is smaller than an inner diameter (94) of the intermediate chamber (30). The introduction of the high pressure fluid (62) and the inner diameter of the outlet section (32) relative to the inner diameter of the intermediate chamber (30) creates a partial vacuum to induce a flow of water (98) and contaminants (22) from a submerged surface (24) of a reservoir (26) through the vacuum apparatus (20). The water (98) and contaminants (22) are subsequently discharged from the reservoir (26) through a discharge hose (44) coupled to the outlet section (32).
Description
- The present invention relates to the field of fluid reservoirs, such as swimming pools. More specifically, the present invention relates to an apparatus for cleaning contaminants from the bottom of such reservoirs.
- In swimming pools, a leaf skimmer is typically utilized to skim off leaves and other such contaminants that float on the surface and that are pulled into the skimmer by the currents of the recirculating water in the pool. Unfortunately, some debris often sinks to the bottom before it has an opportunity to be caught in the skimmer. In reservoirs, such as ponds, decorative pools, fountains and so forth that do not have a skimmer in them, contaminants blown in or dropped in the reservoirs ultimately sink to the bottom of the reservoir. Contaminants that accumulate on the bottom of a pool are unsightly. Moreover, such contaminants also accelerate the formation and growth of algae, and as the contaminants decompose, the water can become cloudy.
- Various devices are available for removing sediment, leaves, grass, rocks, and other contaminants from reservoirs, such as swimming pools, ponds, decorative pools, fountains, and so forth. Many devices are removably connected to the water intake of a pool recirculating system. The devices then vacuum the contaminants from the bottom of the pool and deliver the contaminants to the pool filter from which contaminants may be removed or backwashed.
- While removal of contaminants from the bottom of the pool in this manner may be effective, such an apparatus often necessitates the disassembly of part of the skimmer in order to connect the vacuum hose to the water return for the pool circulation system. In addition, since such devices only function when the reservoir includes a recirculating water supply, these vacuum devices cannot be utilized in reservoirs that do not have a recirculating water supply. Yet another problem is that the contaminants sucked up by the vacuum device can clog the pool filter, decrease filter effectiveness, and eventually damage filtration and pump system components, especially when backwashing is not performed on a regular basis.
- To circumvent the problems of the aforementioned vacuum devices, some prior art pool vacuum systems have been developed that do not couple to the swimming pool recirculating water supply. These pool vacuum systems are referred to herein as filter system bypass vacuums to differentiate them from the pool vacuums, discussed above, that are coupled to the water intake of a recirculating water supply for a pool. These filter system bypass vacuums use the addition of water into the pool to effect their operation. More specifically, water under pressure is supplied to the pool through a hose to force a stream of water through nozzles in the filter system bypass vacuum that are directed toward a debris pickup bag. The high pressure water creates a vacuum to suck up debris from the bottom of a pool. This debris passes through the filter system bypass vacuum and into a basket, filter, or other such debris pickup bag through the exit end of the vacuum. The filtered water then returns to the pool. In pools of all types, it is typically necessary to add additional water to replace water that has evaporated from the pool and/or has been splashed out of the pool. Thus, systems like this can serve the purpose of concurrently supplying the needed water to the pool while functioning to pick up debris from the bottom of the pool.
- Reservoirs, such as swimming pools, ponds, decorative pools, fountains, and so forth, can collect large amounts of leaves, rocks, dirt, and other contaminants through severe intentional or unintentional neglect. Additionally, large quantities of contaminants can rapidly collect in the bottom of a reservoir during a severe rainstorm and/or dust storm.
- Pool vacuums that are coupled to the water intake of a recirculating water supply for a pool may be able to pick up some of the debris. However, contaminants from a very dirty pool can rapidly clog the filter of a recirculating water supply system. Thus, an individual may have to stop frequently during the cleanup process to backwash the pool when the pool has large quantities of contaminants. Frequent backwashing during a single cleaning process is highly undesirable in terms of inconvenience, as well as wear and tear on the pump and filter system components.
- While a filter system bypass vacuum may satisfactorily suck up small amounts of debris, or lightweight debris, such as leaves, grass, and so forth, such a vacuum cannot effectively pick up the large quantities of contaminants found in a neglected or storm ravaged pool. That is, the filter system bypass vacuums tend to generate insufficient suction to pick up large quantities of contaminants and/or heavy contaminants, such as rocks. In addition, tiny particulates, such as dust, may be sucked up by the filter system bypass vacuum only to be released back into the pool through the filter bag of the vacuum. If the filter system bypass vacuum is able to pick up the contaminants, the filter bag of a filter system bypass vacuum rapidly fills with debris, thus necessitating frequent and inconvenient cleaning.
- Both filter system vacuums and filter system bypass vacuums tend to cause significant “kick” in very dirty pools. The term “kick” is referred to herein as the action in which dirt and dust is stirred up from the bottom in a cloud about the vacuum as the vacuum travels across the bottom of the pool. The kick results from the contact of the vacuum head with the bottom of the pool combined with insufficient suction of the vacuum. Contact occurs from the wheels of the vacuum head rolling on the bottom of the pool, as well as, from the conventional stiff bristles of the vacuum head rubbing across the bottom of the pool. Unfortunately, if the dirt and dust floats up from the bottom of the pool, it is less likely that the vacuum will be able to effectively suck up the dirt.
- Due to the problems incurred with both the pool vacuums that are coupled to the water intake and the filter system bypass vacuums, an individual may be compelled to drain their pool to clean the bottom of their severely soiled pool. The individual may then be required to shovel out the accumulated contaminants from the bottom of the empty pool. Such action is highly undesirable because such extreme action is time consuming, labor intensive, and wastes significant quantities of water. Thus, what is needed is a pool vacuum apparatus that is effective for removing large quantities of contaminants found in a neglected or storm ravaged pool.
- Accordingly, it is an advantage of the present invention that an improved vacuum apparatus for cleaning a submerged surface of a reservoir is provided.
- It is another advantage of the present invention that a vacuum apparatus is provided that cleans the pool using an external water source to generate suction.
- Another advantage of the present invention is that a vacuum apparatus is provided that effectively removes contaminants in a severely soiled pool.
- Another advantage of the present invention is that a vacuum apparatus is provided that removes contaminants from the submerged surface of a reservoir while producing minimal kick.
- Yet another advantage of the present invention is that a vacuum apparatus is provided that is of simple construction and is easy to use.
- The above and other advantages of the present invention are carried out in one form by a vacuum apparatus for removing contaminants from a submerged surface of a reservoir. The vacuum apparatus includes an inlet section having a first inlet end and a second inlet end. An intermediate chamber has a first chamber end and a second chamber end, the first chamber end being in fluid communication with the second inlet end. The intermediate chamber exhibits a first inner diameter. An outlet section has a first outlet end in fluid communication with the second chamber end. The outlet section exhibits a second inner diameter that is less than the first inner diameter. A fluid supply pipe resides inside the intermediate chamber and has a fluid port directed toward the outlet section. The fluid supply pipe supplies fresh fluid under pressure from the fluid port toward the outlet section to induce a flow of fluid and the contaminants from the reservoir into the first inlet end of the inlet section and through the intermediate chamber and the outlet section.

Inlet section 28 includes ahead 70 that formsfirst inlet end 34, and aflexible tubular member 72 that terminates atsecond inlet end 36.Second inlet end 36 connects withfirst chamber end 38 ofintermediate chamber 30 via aflanged coupling 74. By way of example,flanged coupling 74 includes afirst segment 76 that extends intosecond inlet end 36 and asecond segment 78 that extends intofirst chamber end 38.Flanged coupling 74 may be press-fit, glued, bolted or otherwise secured to each of flexibletubular member 72 andintermediate chamber 30 per conventional techniques. - In a preferred embodiment, flexible
tubular member 72 is formed from flexible polyvinylchloride (PVC) tubing. Alternatively, flexibletubular member 72 may be formed from polyethylene, polypropylene, polyurethane, nylon, and so forth. In addition,head 70 may be formed from a flexible material, such as PVC, polyethylene, polypropylene, polyurethane, nylon, and so forth, so thathead 70 will also flex to accommodate non-uniformities of submergedsurface 24. -
Head 70 includes anextension member 80 formed atfirst inlet end 36 that is oriented transverse toinlet section 28. In use,extension member 80 is brushed against submergedsurface 24.Extension member 80 may be approximately ten inches in length, so as to sweep an approximate ten inch swath along submergedsurface 24. Aflexible rubber member 79 is coupled to arear edge 81 ofhead 70 along the length ofextension member 80, and apile material 82 is secured toflexible rubber member 79.Pile material 82 may be a synthetic felt that is durable, odor resistant, mildew resistant, and will not break down from moisture. Alternatively,pile material 82 may be another fabric, such as chenille, having a fiber of wool, cotton, nylon, and the like, that stands up from the weave.Pile material 82 may be optionally removably coupled toflexible rubber member 79.Pile material 82 is made removable by use, for example, of hook and loop fasteners so thatpile material 82 can be replaced as it wears out.Flexible rubber member 79 andpile material 82 serve to sweep ordirect contaminants 22 toward an opening 84 (see FIG. 3) ininlet section 28. The use offlexible rubber member 79 andpile material 82 combined with the suction created using vacuum apparatus 20 (discussed below) results in a system that is effective at removing a thick coating of dust from submergedsurface 24 with minimal kick, i.e. minimal generation of a cloud of dust in the water. In addition, the flexibility ofmember 79 enables effective cleaning of the vertical walls of the sides and, if present, stairs, ofreservoir 26. -
Head 70 and flexibletubular member 72 are described as separate parts ofinlet section 28. However, the present invention is not limited to such a configuration. Rather,head 70 and flexibletubular member 72 may be formed as a single, integral unit utilizing fabrication and molding techniques known to those skilled in the art. - FIG. 3 shows a sectional view of
vacuum apparatus 20 along a longitudinal dimension. FIG. 3 draws attention to the variances of the inner diameters ofinlet section 28,intermediate chamber 30, andoutlet section 32. These changes in inner diameter generate a Venturi effect that results in a high level of suction atfirst inlet end 34. This high level of suction is particularly advantageous for removing contaminants from a severely soiled reservoir 26 (FIG. 1).Discharge hose 44, handle 64, andextension member 80, shown in FIGS. 1-2, are not shown in FIG. 3 for simplicity of illustration. - As mentioned briefly above,
interior portion 48 offluid supply pipe 46 resides withinintermediate chamber 30 withfluid port 54 ofinterior portion 48 being located proximatesecond chamber end 40 ofintermediate chamber 30. More specifically,interior portion 48 is approximately axially aligned withintermediate chamber 30. In addition,interior portion 48 of fluid supply pipe 45 is radially positioned toward a center,longitudinal axis 88 ofintermediate chamber 30. In a preferred embodiment,fluid supply pipe 46 is formed from one quarter inch copper tube with the length ofpipe 46 from anelbow 90 tofluid port 54 being approximately two and one half inches. -
Inlet section 28 exhibits a first inner diameter 92.Intermediate chamber 30 exhibits a second inner diameter 94, andoutlet section 32 exhibits a thirdinner diameter 96. First and second inner diameters 92 and 94, respectively, are roughly equivalent, and thirdinner diameter 96 is smaller than second inner diameter 94. In addition, discharge hose 44 (FIGS. 1-2) has a diameter that is smaller than second inner diameter 94. With particular regard to thirdinner diameter 96, thirdinner diameter 96 ofoutlet section 32 is in a range of twenty-five to fifty percent smaller than second inner diameter 94 ofoutlet section 32. - In an exemplary embodiment, first and second inner diameters92 and 94, respectively, are approximately one and one half inches, and third
inner diameter 96 is approximately one inch.Discharge hose 44 friction fits ontooutlet section 32. Thus, in the exemplary embodiment, discharge hose 44 (FIG. 2) may have an inner diameter of approximately one and a quarter inches. This configuration, combined with the one quarter inchfluid supply pipe 46 supplyingfresh water 62, generates suction atfirst inlet end 34 ofinlet section 28. - The suction results from a Venturi effect. That is, as fluid flows past a constricted opening or through a constricted pipe, the velocity of the fluid increases, and the pressure in the system decreases. Accordingly, a Venturi effect occurs when
fresh water 62 entersintermediate chamber 30 atsecond chamber end 40 and immediately flows into the constrictedoutlet section 32. The Venturi effect occurring atoutlet section 32 results in a corresponding pressure decrease ininlet section 28 relative to the pressure outside ofvacuum apparatus 20. Consequently, this pressure decrease results in suction which induces a flow ofwater 98 mixed withcontaminants 22 fromreservoir 26 intofirst inlet end 34 ofinlet section 28. The relatively large size of first and second diameters 92 and 94, respectively, allow large profile contaminants, such as leaves, to be drawing intovacuum apparatus 20. Accordingly,water 98 andcontaminants 22 are effectively drawn throughintermediate chamber 30 andoutlet section 32.Water 98 andcontaminants 22 are subsequently discharged fromreservoir 26 throughdischarge hose 44. - To use
vacuum apparatus 20, a user attaches fluid supply hose 60 (FIG. 1) tocoupling 58 and attachespole 68 toquick change handle 64.Vacuum apparatus 20 is submerged intoreservoir 26, with a distal end ofdischarge hose 44 remaining outside ofreservoir 26. A water source coupled tofluid supply hose 60 is turned on to supplyfresh water 62 fromfluid port 54 to intointermediate chamber 30 and out ofoutlet section 32. When pressure drops sufficiently,vacuum apparatus 20 will begin to drawwater 98 combined withcontaminants 22 from submergedsurface 24. The user then sweepshead 70 across submerged surface 24 (FIG. 2) withtubular member 72 andrubber member 79 flexing to accommodate non-uniformities in submergedsurface 24, changes in depth ofreservoir 26, and distance from the edge ofreservoir 26. Once submergedsurface 24 is clean, the suction can be stopped merely by turning off the water source supplyingfresh water 62. Although some ofwater 98 is removed fromreservoir 26 through vacuum apparatus 20 (roughly nine gallons per minute),reservoir 26 need not be completely drained in order to clean a very soiled pool. Thus, significant savings in terms of time, labor, and water is achieved usingvacuum apparatus 20. - Referring to FIGS.4-5, FIG. 4 shows an-exploded perspective view of a
vacuum apparatus 100 in accordance with an alternative embodiment of the present invention, and FIG. 5 shows a perspective view ofvacuum apparatus 100.Vacuum apparatus 100 operates on the same principle as vacuum apparatus 20 (FIG. 1) to removecontaminants 22 from submergedsurface 24 ofreservoir 26. -
Vacuum apparatus 100 includes aninlet section 102, anintermediate chamber 104 in fluid communication withinlet section 102, and anoutlet section 106 in fluid communication withintermediate chamber 104. Afluid supply pipe 108 resides inintermediate chamber 104, and includes acoupling 110 configured for connection tofluid supply hose 60.Discharge hose 44 is coupled to anoutlet end 112 ofoutlet section 106, and quick change handle 64 is coupled tovacuum apparatus 100 for interconnection withpole 68. -
Inlet section 102 ofvacuum apparatus 100 includes ahead 114 and atubular member 116.Tubular member 116,intermediate chamber 104, andoutlet section 106 are manufactured as an integral unit, and asleeve portion 118 ofhead 114 slides overtubular member 116.Head 114 readily friction fits ontotubular member 116 for engagement with or removal fromtubular member 116. In a preferred embodiment,head 114 includesextension member 80 andpile material 82. However,pile material 82 surroundsinlet section 102 at aninlet end 119 ofhead 114. More specifically,pile material 82 is coupled aboutextension member 80 and an opening (not seen) intoinlet section 102. Due to the friction fit ofhead 114 ontotubular member 116,head 114 may be easily replaced aspile material 82 wears out, or as enhancements to the shape and/or size ofhead 114 evolve. -
Tubular member 116 andhead 114 may be fabricated from a rigid plastic material. Alternatively,tubular member 116 may not be integral withintermediate chamber 104, but may instead be fastened tointermediate chamber 104 through standard manufacturing methods. As such,tubular member 116 andhead 114 can be produced from flexible material for enablingvacuum apparatus 100 to accommodate non-uniformities in the smoothness of submergedsurface 24. - The inner diameters
intermediate chamber 104 andoutlet section 106 correspond respectively to second inner diameter 94 and thirdinner diameter 96, discussed in connection with FIG. 3. However,tubular member 116 exhibits a firstinner diameter 122 that is smaller than the inner diameter ofintermediate chamber 104. Although, suction is achieved due to the reduction of diameter from the larger second inner diameter 94 (FIG. 3) of intermediate chamber 30 (FIG. 3) to the smaller third inner diameter 96 (FIG. 3) of outlet section 32 (FIG. 3), it has been discovered that the smaller firstinner diameter 122 oftubular member 116 relative to the inner diameter ofintermediate chamber 104 further enhances this suction. Such enhanced suction is particularly advantageous when removing fineparticulate contaminants 22, such as, dust, from submergedsurface 24 while producing minimal kick. -
Tubular member 116 forms an elongated neck through which water 120 andcontaminants 22 travel as they are drawn throughvacuum apparatus 100.Vacuum apparatus 100 generates suction in a similar manner to vacuumapparatus 100. However, the elongated neck oftubular member 116 with the smaller inner diameter relative to the inner diameter ofintermediate chamber 104 may serve to further enhance the suction capability ofvacuum apparatus 100. - In summary, the present invention teaches of an improved vacuum apparatus for cleaning a submerged surface of a reservoir, such as a swimming pool. The vacuum apparatus utilizes an external water source that generates suction through a Venturi effect to draw water and contaminants from the reservoir. The constriction of the inlet and outlet sections of the vacuum apparatus relative to the intermediate chamber, and the positioning of a fluid supply pipe within the intermediate chamber proximate the outlet section generates significant suction to effectively remove contaminants from a severely soiled pool. Moreover, unlike conventional apparatuses, the enhanced suction capability of the vacuum apparatus readily removes contaminants from deep reservoirs, such as, eight to ten foot diving pools. In addition, the shape of the vacuum head and the inclusion of the flexible rubber member and the pile material on the vacuum head serve to sweep, or draw in, contaminants from the submerged surface of the reservoir while producing minimal kick. The operation of the vacuum apparatus using an external water source is simpler than connection to the recirculating water supply of a pool, and enables the vacuum apparatus to be used in reservoirs that do not include a recirculating water supply system.
- Although the preferred embodiments of the invention have been illustrated and described in detail, it will be readily apparent to those skilled in the art that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims. For example, the principles of the present invention may be adapted for use to remove particulate contaminants from the submerged surface of a reservoir containing a fluid other than water. In addition, the discharge hose of the vacuum apparatus can be adapted to couple to a water intake of a recirculating water supply for a pool, so that the water introduced into the vacuum apparatus can be returned to the reservoir.
