Abstract

A water circulation system includes a motor, a plurality of first vanes and a plurality of second vanes. The motor includes a first output shaft and a second output shaft. The first vanes are connected to the first output shaft and driven by the motor to circulate warm water for a warm water pool. The second vanes are connected to the second output shaft and driven by the motor to circulate cold water for a cold water pool

         3 . The water circulation system as claimed in  claim 2 , wherein the heating device comprises at least one electric heating tube. 
     
     
         4 . The water circulation system as claimed in  claim 1 , wherein after drawn out of the warm water pool, a part of the warm water is introduced to the motor, absorbs heat from the motor, and is sent back to the warm water pool. 
     
     
         5 . The water circulation system as claimed in  claim 1 , further comprising:
 a refrigeration device configured to remove heat from the cold water after the cold water is drawn out of the cold water pool and before the cold water is sent back to the cold water pool;   wherein the refrigeration device in operation generates heat that is provided for the warm water after the warm water is drawn out of the warm water pool and before the warm water is sent back to the warm water pool.   
     
     
         6 . The water circulation system as claimed in  claim 5 , wherein:
 the refrigeration device comprises a compressor;   after drawn out of the warm water pool, the warm water is introduced to the compressor, absorbs heat from the compressor, and is sent back to the warm water pool.   
     
     
         7 . The water circulation system as claimed in  claim 6 , further comprising a water pump configured to pump the warm water to the compressor. 
     
     
         8 . The water circulation system as claimed in  claim 1 , further comprising:
 a refrigeration device configured to remove heat from the cold water after the cold water is drawn out of the cold water pool and before the cold water is sent back to the cold water pool;   a multi-way valve;   wherein after drawn out of the warm pool, a part of the warm water flows through the multi-way valve to the motor, absorbs heat from the motor, and is sent back to the warm water pool;   wherein the refrigeration device comprises a compressor;   wherein after drawn out of the warm pool, another part of the warm water flows through the multi-way valve to the compressor, absorbs heat from the compressor, and is sent back to the warm water pool.   
     
     
         9 . The water circulation system as claimed in  claim 1 , further comprising:
 a refrigeration device configured to remove heat from the cold water after the cold water is drawn out of the cold water pool and before the cold water is sent back to the cold water pool;   a fan;   wherein the refrigeration device comprises a compressor, a condenser, an expansion device, and an evaporator which operate to form a refrigeration cycle;   wherein the fan is configured to dissipate heat from the condenser and the compressor.   
     
     
         10 . The water circulation system as claimed in  claim 9 , wherein airflow is generated by the fan, and the airflow absorbs the heat generated by the condenser and the compressor and flows to a surrounding of the circulated warm water. 
     
     
         11 . The water circulation system as claimed in  claim 1 , wherein the warm water pool and the cold water pool are made of stiff or flexible material. 
     
     
         12 . The water circulation system as claimed in  claim 11 , wherein the flexible material comprises foam. 
     
     
         13 . The water circulation system as claimed in  claim 1 , wherein the warm water pool and the cold water pool are inflatable products. 
     
     
         14 . The water circulation system as claimed in  claim 1 , wherein the warm water pool and the cold water pool have a partition wall disposed therebetween. 
     
     
         15 . The water circulation system as claimed in  claim 14 , wherein:
 the partition wall comprises a connecting space for connecting the warm water pool and the cold water pool;   a valve is disposed at the connecting space, allowing or obstructing connection between the warm water pool and the cold water pool.   
     
     
         16 . A water circulation system, comprising:
 a motor comprising a first output shaft and a second output shaft;   a plurality of first vanes fixed to the first output shaft and driven by the motor to circulate warm water for a warm water pool;   a plurality of second vanes fixed to the second output shaft.   
     
     
         17 . The water circulation system as claimed in  claim 16 , further comprising:
