Abstract
A water recreational apparatus has a water basin, a pump, a filter and a filter opening. The water basin has side walls and a bottom wall. The water recreational apparatus further includes one or more downwardly directed sweep jets disposed within the water basin proximate to the side walls. The sweep jets are disposed above the bottom wall by a distance of less than 10 inches. The sweep jets are in fluid tight communication with the discharge side of the pump so that water can be pumped through the sweep jets to roil water at the bottom of the water basin. By roiling the water at the bottom of the water basin, debris which tends to collect along the bottom of the water basin is moved upward within the water basin to where it can be removed via the filter opening and the filter.
Description
- Water recreational apparatuses, such as portable spas, hot tubs, above ground pools and water recirculating bath tubs have become very popular. Many such water recreational apparatuses have water filters wherein a portion of the water within the basin is withdrawn via a filter opening, filtered to remove suspended debris and reintroduced into the water basin.
- A problem with the use of water recreational apparatuses of the prior art concerns the tendency of debris to collect at the bottom of the apparatus where the water at the bottom of the apparatus is relatively stagnant, compared to water disposed high above the bottom of the basin. Because the water is relatively stagnant, the debris is not easily moved to the filter opening. The debris therefore tends to accumulate at the bottom of the basin.
- Accordingly, there is a need for a water recreational apparatus which avoids this problem in the prior art.
- The invention satisfies this need. The invention is a water recreational apparatus comprising (a) a water basin having side walls and a bottom wall, (b) a pump having a suction side and a discharge side, and (c) one or more downwardly directed sweep jets disposed within the water basin proximate to the side walls, the sweep jets being disposed above the bottom wall by a distance of less than 10 inches, the one or more downwardly directed sweep jets being in fluid tight communication with the discharge side of the pump.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description, appended claims and accompanying drawings where:
- FIG. 1 is a cross-sectional side view of a water apparatus having features of the invention;
- FIG. 2 is a diagrammatic isometric view of a water recreational apparatus having features of the invention;
- FIG. 3 is a diagrammatic plan view of the water recreational apparatus illustrated in FIG. 2;
- FIG. 4 is a cross-sectional side view of another water recreational apparatus having features of the invention;
- FIG. 5 is a cross-sectional side view of still another water recreational apparatus having features of the invention; and
- FIG. 6 is a cross-sectional side view of still another water recreational apparatus having features of the invention.
- The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well.
- The invention comprises a water
recreational apparatus 10, such as a portable spa, hot tub, above ground pool or water recirculating bath tub. The waterrecreational apparatus 10 comprises awater basin 12, afilter 14, a pump and one or more downwardly directedsweep jets 18. - The
water basin 12 typically has a plurality of generallyvertical side walls 20 and a generallyhorizontal bottom wall 22. Thewater basin 12 also typically comprises one or moreuser seat locations 24 and a plurality of recreational jets (not shown) disposed in theupper portions 26 of theside walls 20. The water recreational jets provide an inlet stream of pressurized and aerated water to massage, amuse and otherwise impact the upper torsos of users disposed at theuser seat locations 24. The recreational jets are disposed so as to project pressurized and aerated water in a generally horizontal direction within thewater basin 12. The recreational jets are disposed more than 10 inches above thebottom wall 22 of thewater basin 12. - The
water basin 12 further comprises at least one filter opening 28 for allowing a slip stream ofwater 29 to flow from thewater basin 12 and into thefilter 14, thefilter 14 typically being disposed external of thewater basin 12. In the embodiments illustrated in the drawings, thefilter opening 28 is disposed in theupper portions 26 of theside walls 20. Additional filter openings (not shown) can also be provided disposed, for example, in thebottom wall 22 of thewater basin 12. - The
pump 16 is typically a centrifugal pump driven by anelectric motor 30. The pump has asuction side 32 and a discharge side 34. The discharge side 34 of thepump 16 is disposed in fluid tight communication with thefilter 14 via asuction line 36. The discharge side 34 of thepump 16 is connected viadischarge lines 38 to the recreational jets in theupper portions 26 of theside walls 20 and to thesweep jets 18 disposed in the lower portions 40 of theside walls 20. - In the embodiment illustrated in the drawings, the one or
more sweep jets 18 comprise a plurality ofsweep jets 18. In FIG. 1, twosweep jets 18 are illustrated. In FIGS. 2 and 3, threesweep jets 18 are illustrated. Thesweep jets 18 are downwardly directed openings for allowing the pumping of water from thepump 16 to the bottom of thewater basin 12. Thesweep jets 18 can be disposed so that water discharged from thesweep jets 18 is projected substantially vertically. Thesweep jets 18 can alternatively be disposed at an angle with respect to the vertical. In the embodiment illustrated in FIG. 2, each of the three sweep jets is 18 disposed at an angle with respect to the vertical, such that each of thesweep jets 18 projects downwardly to the right. By this configuration, the discharge of water from the combined threesweep jets 18 tends to the swirl water at the bottom of thewater basin 12 in a counter clockwise direction. - The
sweep jets 18 are disposed above thebottom wall 22 of thewater basin 12 by less than about 10 inches. In a typical embodiment, thesweep jets 18 are disposed between about 3 inches and about 6 inches above thebottom wall 22 of thewater basin 18. In a spa having a water basin capacity of about 100 gallons, 4 to 8 equally spaced apartsweep jets 18 can be used. For such a spa, the total water discharged from eachsweep jet 18 is typically between about 10 gpm and about 400 gpm. Thus, the totality of the water discharged from all of thesweep jets 18 is typically between about 10 gpm and about 60 gpm. - As illustrated in FIG. 1, the
water basin 12, thefilter 14, thepump 16, thesuction lines 36 and thedischarge lines 38 are housed within aspa surround 41. - FIG. 4 illustrates another typical embodiment of the invention. In this embodiment, the
suction lines 36 comprise a sidewall discharge port 43 and thedischarge lines 38 further comprise aheater 42, amain manifold 44 and asweep jet manifold 46. Theheater 42 can be used to heat water circulated through thedischarge lines 38. Themain manifold 44 divides water in thedischarge lines 38 into two streams. In a first stream, the water is routed to the recreational jets in theupper portions 26 of theside walls 20 via recreational jetmain lines 48. The second stream is routed to thesweep jet manifold 44. Thesweep jet manifold 44 separates water into individual streams for each of thesweep jets 18. In the embodiment illustrated in FIG. 4, there are foursweep jets 18, one disposed in each of the fourside walls 20. - FIG. 5 illustrates another embodiment of the invention. In this embodiment of the invention, a portion of the water from the
discharge lines 38 flows to anozone injector 50 disposed along thebottom wall 22 of thewater basin 12. Also, adrain valve 52 is provided in thedischarge lines 38. - FIG. 6 illustrates yet another embodiment of the invention. In this embodiment of the invention, a pair of
pumps 16, driven by asingle motor 30, is used. One of thepumps 16 provides water to thesweep jets 18 while theother pump 16 provides water to theheater 42, the recreational jets and to theozone injector 50. - In operation, debris, such as dirt and other solid materials, typically accumulate along the
bottom wall 22 of thewater basin 12. As explained in the Background Section, this debris along thebottom wall 22 is difficult to move to thefilter opening 28, especially when thefilter opening 28 is disposed in theupper portion 26 of theside walls 20. By use of thesweep jets 18, water discharged from thepump 16 through thesweep jets 18 roils the water at the bottom of thewater basin 12 sufficiently to move debris along thebottom wall 22 of the water basin away from thebottom wall 22. In a preferred embodiment, such roiling of the water in the bottom of thewater basin 12 is sufficient to displace debris at the bottom of thewater basin 12 all the way to the upper water levels in thewater basin 12, where the debris can be withdrawn in theslip stream 29 flowing through afilter opening 28 disposed in theupper portion 26 of theside walls 20. Theslip stream 29 passes to and through thefilter 14 where debris, once disposed along thebottom wall 22 of thewater basin 12, is filtered out. - Thus, the invention provides a simple and inexpensive way of preventing the build-up of unwanted debris at the bottom of the water basin of a water recreational apparatus.
- Having thus described the invention, it should be apparent that numerous structural modifications and adaptations may be resorted to without departing from the scope and fair meaning of the instant invention as set forth hereinabove and as described hereinbelow by the claims.
