Water circulating apparatus and method for a swimming pool

Abstract

A water circulating apparatus and method for using in a built swimming pool or a swimming pool during building. The apparatus includes: a container disposed in the swimming pool and the container has a water outlet and a water inlet respectively on a front end and a rear end, the water outlet and inlet are under the water level in the swimming pool, and a water circulation actuating mechanism provided on the front end of the container for pushing and lifting water from the front end of the container and controlling flow rate of water to flow out from the water outlet to the other end of the swimming pool, and to cause the water in the rear end of the swimming pool to flow into the container from the water inlet, and to flow toward the water outlet through the container, thus effecting water circulation in the swimming pool.

1 . A water circulating apparatus adapted for use in a small swimming pool, comprising:
 a container, disposed in said swimming pool, having a water outlet and a water inlet respectively on its front end and its rear end, said water outlet and said water inlet being under the water level of said swimming pool; and   a water circulation actuating mechanism provided on a front end of said container for pushing and lifting water from the front end of said container and controlling flow rate of water to flow out from said water outlet to the other end of said swimming pool, and to cause the water in the rear end of the swimming pool to flow into said container from said water inlet of said container, and to flow toward said water outlet through the container, thus effecting water circulation in the swimming pool.   
   
   
       2 . The water circulating apparatus as in  claim 1 , wherein said container includes a bottom case, a front case and a rear case extended upwards respectively from two ends of said bottom case, said bottom case, front case and rear case being communicated with each other, said water outlet being formed on the top of the inner side of said front case and said water inlet being formed on the top of the inner side of said rear case. 
   
   
       3 . The water circulating apparatus as in  claim 2 , wherein the position of said water outlet of said front case is higher than that of said water inlet of said rear case. 
   
   
       4 . The water circulating apparatus as in  claim 2 , wherein the width of said water outlet of said front case is narrower than that of said water inlet of said rear case. 
   
   
       5 . The water circulating apparatus as in  claim 2 , wherein said water circulation actuating mechanism includes at least one electric motor, a plurality of gearing members and a plurality of turbine vane sets for pushing and lifting water from the front end of the bottom case and discharging said water out of said water outlet. 
   
   
       6 . The water circulating apparatus as in  claim 5 , wherein said water circulation actuating mechanism further includes a plurality of guiding tubes, said guiding tubes enclose said turbine vane sets respectively. 
   
   
       7 . The water circulating apparatus as in  claim 6 , wherein said guiding tubes are divided into a front guiding tube group and a rear guiding tube group, and the top end of said rear guiding tube group is higher than that of said front guiding tube group. 
   
   
       8 . The water circulating apparatus as in  claim 6 , wherein said water circulation actuating mechanism further includes a guiding plate disposed on the top of said guiding tubes. 
   
   
       9 . The water circulating apparatus as in  claim 5 , wherein said water circulation actuating mechanism is provided inside said front case. 
   
   
       10 . The water circulating apparatus as in  claim 5 , wherein said turbine vane sets of said water circulation actuating mechanism are provided inside said front case, while said electric motor is disposed outside said front case. 
   
   
       11 . The water circulating apparatus as in  claim 1 , wherein said container is attached to and circles the inner peripheries of said swimming pool. 
   
   
       12 . The water circulating apparatus as in  claim 1 , wherein said water circulation actuating mechanism comprises an air blower and a plurality of nozzles piped with said air blower. 
   
   
       13 . The water circulating apparatus as in  claim 1 , wherein said water circulating apparatus is provided with a detector in electric connection with said water circulation actuating mechanism to detect the speed of a swimmer for adjusting output power of said water circulation actuating mechanism to control flow rate of water in said swimming pool in response to the speed of the swimmer. 
   
   
       14 . A water circulating method comprising the following steps:
 a. providing a container in a swimming pool, wherein said container has a water outlet and a water inlet respectively on the front end and the real end of the swimming pool, and said water outlet and said water inlet are under water level of said swimming pool; and   b. providing a water circulation actuating mechanism on the front end of said container for pushing and lifting water from the front end of said container and controlling flow rate of water to flow out from said water outlet to the other end of said swimming pool, and to cause the water in the rear end of the swimming pool to flow into said container from said water inlet of said container, and to flow toward said water outlet through the container, thus effecting water circulation in the swimming pool.
