Abstract:
A spa cooling fan assembly having an exhaust/inlet fitting mounted in a wall of a spa cabinet, a spa cabinet wall having an opening therein, said spa cabinet enclosing a water circulating pump, said spa cooling fan and spa cabinet wall comprising:a fan motor frame secured within an interior of said spa cabinet wall; an air flow passageway formed within said fan motor frame, said air flow passageway having an air exit opening and an air entrance opening; a plurality of louvers held by said exhaust/inlet fitting, said plurality of louvers including means for closing and opening said plurality of louvers to open or close the flow of air through said exhaust/inlet fitting; a turbine water inlet held by said fan motor frame, said turbine water inlet being connected to a water inlet flow path and to a water outlet line of said water circulating pump; a turbine held by said fan motor frame, said turbine having a turbine inlet connected to said turbine water inlet and said turbine having a turbine outlet and said water flow path passing a plurality of turbine blades said turbine having an output shaft coaxially mounted with respect to said air flow passageway; a turbine water outlet held by said fan motor frame, said turbine water outlet being connected to said water flow path and said water outlet being connected to a water inlet of said water circulating pump; and a fan connected to said turbine output shaft, said fan extending over a majority of said air flow passageway, whereby when said water circulating pump is operating, water enters said turbine water inlet, passes over said plurality of turbine blades and exits said turbine water outlet causing said fan to turn and causes air to pass through said exhaust/inlet fitting in said spa wall when said louvers are in an open configuration in said air flow passageway.
