Patent ID: 7296308

Claim:
A swimming pool water circulating apparatus for the circulation of substantially all water in an above-ground pool having a floor and a continuously curved side wall with a pressurized water inlet and a water outlet both in the side wall and proximate to the surface of the pool water with the outlet in the direction of circulation being downstream of the inlet, the apparatus comprising: a rigid hollow jet tube at least partially submerged in the water and in fluid communication with the water inlet, the jet tube being adjacent to a portion of a pool side wall and extending substantially vertically in the pool and substantially entirely along the side wall from the water surface to the pool floor; means defining a plurality of nozzles penetrating said tube along substantially the entire length of the jet tube that is under the surface of the water and through which water from the water inlet flows through the nozzles directly into the pool water to cause a current that circulates the pool water and any debris along the side wall to the water outlet to discharge the debris from the pool, the nozzles being disposed along a vertical centerline aligned with the vertical jet tube and directed to produce jets of water from the water inlet parallel to and substantially along the entire periphery of the side wall to the water outlet; means defining at least one slot at the bottom end of the jet tube and proximate to the pool floor, the slot being directed to produce a water jet substantially horizontally along the pool floor toward the center of the pool to cause any debris on the pool floor to be picked up by the current caused by the nozzles; and means providing water-tight connections enabling water from the water inlet to flow only through the nozzles and the slot, the water-tight means comprising an end cap at the bottom end of the jet tube and a rigid elbow-shaped water-tight adaptor connecting the top of the jet tube to the water inlet.
