Contrast-Healing Water Spa System

US Patent:
4761838, Aug 9, 1988
Filed:
May 4, 1987
Appl. No.:
7/046834
Inventors:
John W. Hargrove - Houston TX
International Classification:
A61H 3302
US Classification:
4542
Abstract:
In one exemplar embodiment, a contrast-healing water spa system is disclosed that includes a single monolithically formed tub having two approximately equal-sized chambers that are separated by an integrally formed insulated structural wall that will provide hot aerated water in one cabinet and cold quiet water in the other chamber. A hot water circulating pump withdraws water from the hot water chamber at a predetermined flow rate, and the water is then passed through a filter and heater before being injected into the hot water chamber through high-pressure injection ports. A cold water circulating pump withdraws water from the cold water chamber at a predetermined flow rate, and the water is then passed through a filter and cooled by a sidestream mounted chiller before being returned to the cold water chamber. A single ozone generator is interconnected between the cold and hot water lines to add disinfectant to both water circulating systems. A cross-feed line and adjustable valve are disposed between the hot and cold water return lines after the ozone disinfectant is added to permit cross-feed of a selected quantity of hot water into the cold water system.
