  • Patent number: 10596439
    Abstract: An improved swim spa is described which has a tank having a head end and a foot end filled with water. A forward current is created by pumping equipment which directs the forward current from a head end of the tank, past a swimmer in the water to a foot end of the tank. The pumping equipment may be attached to a removable wall insert to which may be removed to allow easy repair and maintenance. The forward current allows the swimmer to swim in place. The width of the forward current is chosen to be at least twice its depth. A diverter at the foot end of the tank has a curved surface for redirecting the forward current toward the sidewalls and then back toward the head wall in a horizontal plane and downward and back toward the head wall in a vertical plane.

  • Patent number: 8905625
    Abstract: The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber.

  • Patent number: 8392027
    Abstract: A spa control system that measures the flow of water through the heater and accurately reports water temperature in the spa using only one solid-state sensor in the heater. The rate of flow is determined by energizing the pump, with the heater still de-energized, and observing the rate in which the moving water cools the inside of the heater. If there is no circulation of water through the heater, the temperature of the sensor will continue to rise from the energy applied when the heater was briefly energized. This rise will be quite significant and a clear indication of a flow problem. If the flow is found to be adequate, the heater will be energized for a normal period of time. The sensor is now carefully monitored for a sudden increase in temperature, which would indicate loss of a normal flow of water.

  • Publication number: 20110004993
    Abstract: A swimming pool designed for stationary swimming uses Venturi-based eductor jets to generate a forceful water flow augmented by entrained pool water drawn from within the pool enclosure. The eductor jets use the kinetic energy of the inlet flow to entrain the low-pressure pool water, completely mix the two, and then discharge the mixture as an augmented outlet flow. The energy from the motive inlet flow is transferred to the entrained pool water via the Venturi effect. As the motive inlet water passes through a tapered nozzle in the eductor jet, kinetic energy increases and pressure decreases. This produces a Venturi effect which draws surrounding pool water into the Venturi orifice of the eductor jet. Consequently, the volume of the outlet flow from the eductor jets is 3 to 5 times the volume of the inlet flow. A larger and more powerful stream of water is thereby discharged into the pool enclosure and provides optimal resistance for in-place swimming in an energy-efficient manner.

  • Publication number: 20090293188
    Abstract: A hydrotherapy apparatus used with a pool includes a hydrotherapy jet having an inlet and an outlet through which a pressurized water jet is expelled. A mounting structure immerses the hydrotherapy jet into water in the pool and is adjustable for moving the hydrotherapy jet into different positions to direct a water jet against different parts of the body of a person in the pool. A floating recliner supports a user of almost any size in a seated or reclining position while at least partially immersed in the water in the pool. A water circulation system pumps water in the pool into the inlet and out the outlet of the hydrotherapy jet to provide the pressurized water jet.

  • Publication number: 20090133187
    Abstract: Disclosed herein is a wakeboard-only artificial pool system. The system includes an artificial pool. A model boat is installed at a front position in the artificial pool and is rotatably coupled at a lower end and both sides thereof to support members such that an inclination of the model boat can be adjusted and the adjusted angle can be maintained, while the model boat is supported during wakeboarding. A high-speed injection means produces a wake under the lower portion of the model boat as if water were colliding with the front of the operating model boat, and sprays water on the lower end of a bow of the model boat at high speed, thus creating a current on the surface of the artificial pool so as to help a user float on water. A circulation means circulates water fed into and discharged from the artificial pool.

  • Patent number: 7526820
    Abstract: The Invention is a swimming machine operated by a hydraulic pump and hydraulic motor. A first and a second tubular rail support the swimming machine in a swimming pool and are configured to resemble a swimming pool ladder and thus disguise the swimming machine. The configuration of the tubular rails substantially prevents use of the swimming machine as a ladder. A radio-operated remote control proportional relief valve selectably bleeds hydraulic fluid from the high pressure side to the low pressure side of the hydraulic pump, allowing remote control of the velocity of water in the pool.

  • Patent number: 7296308
    Abstract: The invention comprises, in one form thereof, a water circulator that connects to the pressurized water inlet in a swimming pool. Water from the pool is pumped through the pool's filter system and into the water circulator through the pool inlet. The water circulator includes a jet tube that is vertically oriented and proximate to the pool's side wall. The pressurized water exits the jet tube through several nozzles in the jet tube. The nozzles direct the pressurized water along the side wall to thereby direct debris toward the pool outlet. The pool outlet carries the debris and water to the pool's filter system. The nozzles direct the water away from the pool outlet so that the water current travels along the majority of the side wall before reaching the pool outlet. Thus, more debris may be picked up in the current and slower moving water passes the pool outlet. The jet tube further includes one or more outlets proximate to the pool floor.

  • Patent number: 7160446
    Abstract: A filter housing for a portable spa utilizes a coaxial channel structure at the flow output of the filter housing to separate the water flow from the filter housing. In one embodiment, the water from the filter housing, exiting at the bottom of the housing, is piped by way of a high pressure pump, to the jets in the spa. The water from the filter housing taken at about halfway between the top and bottom of the filter housing is piped, by way of a circulation pump to a heater and a water purifier system back into the spa, preferably to a return aperture in the footwell of the spa. In another embodiment water exiting the filter housing is split into separate flow paths at the bottom of the filter housing, to the jets in the spa and into the circulation loop back into the spa.
