Abstract

A swimming pool circulation and cleaning system includes a first zone with a plurality of stationary wall inlet nozzles and a second zone with a plurality of pop-up nozzles. The stationary wall inlet nozzles are strategically located in the walls of the swimming pool. Each stationary wall inlet nozzle comprises several tangential openings for directing the forced water flows downwardly towards the pool floor. The pop-up nozzles are strategically located in the pool floor to work in conjunction with the stationary wall inlet nozzles to continue the water flow from the stationary wall inlet nozzles in a direction towards the main pool drain. The pop-up nozzles may be non-rotating or rotating only about 90 degrees. A water recirculation system can be operated to re-circulate and deliver the swimming pool water either sequentially or simultaneously to the stationary wall inlet nozzles and the floor pop-up nozzles.

Claims

exact text as granted — not AI-modified
1 . A swimming pool circulation and cleaning system, comprising:
 at least a first zone located in the wall of a swimming pool and comprising a plurality of stationary wall inlet nozzles, each stationary wall inlet nozzle including at least one tangential opening for delivering a forced water flow in a downward direction toward the pool floor; and   at least a second zone located in the floor of the swimming pool and comprising a plurality of pop-up nozzles, each pop-up nozzle having at least one tangential opening for delivering a forced water flow along the floor to continue the direction of the forced water flow from each wall inlet nozzle towards the main pool drain.   
     
     
         2 . The system of  claim 1 , further comprising a water recirculation system for selectively operating the stationary wall inlet nozzles of the first zone and the pop-up nozzles of the second zone in a sequential manner or in a simultaneous manner. 
     
     
         3 . The system of  claim 2 , wherein the water recirculation system comprises a variable speed pump and a valve device for operating the stationary wall inlet nozzles and the pop-up nozzles in a sequential or simultaneous manner. 
     
     
         4 . The system of  claim 2 , wherein the water recirculation system comprises a variable speed pump and a water distribution valve for operating the stationary wall inlet nozzles and the pop-up nozzles in a sequential or simultaneous manner. 
     
     
         5 . The system of  claim 1 , wherein the pop-up nozzles are non-rotating pop-up nozzles. 
     
     
         6 . The system of  claim 1 , wherein the pop-up nozzles are rotating pop-nozzles. 
     
     
         7 . The system of  claim 5 , wherein the rotating pop-up nozzles rotate at about 90 degrees or less. 
     
     
         8 . The system of  claim 1 , wherein at least the first zone of stationary wall inlet nozzles comprises at least one row of stationary wall inlet nozzles around the wall of the swimming pool. 
     
     
         9 . The system of  claim 1 , wherein at least the second zone of pop-up nozzles comprises at least one row of pop-up nozzles along the floor of the swimming pool. 
     
     
         10 . A method for circulating water and cleaning a swimming pool, comprising:
 strategically locating at least a first zone in the walls of the swimming pool comprising a plurality of stationary wall inlet nozzles, each stationary wall inlet nozzle including at least one tangential opening for delivering a forced water flow in a downward direction toward the pool floor;   strategically locating at least a second zone in the floor of the swimming pool comprising a plurality of pop-up nozzles, each pop-up nozzle having at least one tangential opening for delivering a forced water flow along the floor to continue the direction of the forced water flow from each stationary wall inlet nozzle towards the main pool drain;   providing a water recirculation system in association with the stationary wall inlet nozzles of the first zone and the pop-up nozzles of the second zone; and   selectively operating the water recirculation system for supplying water to the stationary wall inlet nozzles and to the pop-up nozzles either sequentially or simultaneously.   
     
     
         11 . The method of  claim 10 , further comprising:
 providing non-rotating pop-up nozzles in the second zone.   
     
     
         12 . The method of  claim 10 , further comprising:
 providing rotating pop-up nozzles in the second zone.   
     
     
         13 . The method of  claim 12 , wherein the rotating pop-up nozzles rotate no greater than 90 degrees. 
     
     
         14 . The method of  claim 10 , the steps further comprising:
 providing at least one row of the stationary wall inlet nozzles around the walls of the swimming pool.   
     
     
         15 . The method of  claim 10 , the steps further comprising:
 providing at least one row of the pop-up nozzles along the floor of the swimming pool.
