Floating therapy pool

Abstract

A floating therapy apparatus or 'spa' is provided which is adapted to be floating in and to utilize the filtration and heating systems of a conventional swimming pool comprising a substantially water impermeable enclosure, which is immersed and supported in a conventional swimming pool, having only the upper peripheral edge of said enclosure above the surface of said pool. A water supply inlet is used to circulate heated filtered water from said pool filtration system into said enclosure, the spa water may be discharged into the main pool and/or a water return may be used to discharge water from the enclosure. Valving means for channelling substantially all or at least a disproportionately high amount of the capacity of the swimming pool water heater water is used as the feed water for said enclosure. An air discharge means in the lower part of said enclosure is employed to introduce air into the enclosure and create pressure waves in said enclosure with suitable air generating means being used for supplying pressurized air into said enclosure through said air discharge opening. The spa heated water requirements comprise a basically closed circulatory system for the heated water. A certain greater percentage of water must be circulated into the spa enclosure than is pulled out by the suction pump to provide make-up water for leakage and to, therefore, maintain an adequate water supply in the spa enclosure to keep it at the desired fill volume.
