Pool water treatment device with simplified hydraulic priming, and pool equipped with such a device

Abstract

Treatment device for treating water of a pool comprising a hydraulic circuit between a suction port and a return port, a pumping device and a treatment unit interposed in the hydraulic circuit, wherein at least one suction port comprises a flap configured so that it is able to create a pressure drop in the return direction of a fluid, and wherein said flap has a reflux orifice allowing fluid to return through the suction port.

1 . A treatment device for treating water of a pool, comprising:
 a water pumping device interposed in a hydraulic circuit in order to generate therein a flow of water between at least one suction port for the water of the pool and at least one return port for the water of the pool,   a water treatment unit interposed in the hydraulic circuit for treating the water circulating therein,   
       wherein
 at least one suction port of said hydraulic circuit having a passage cross-section in the suction direction has, in the return direction, a non-zero passage cross-section smaller than the passage cross-section in the suction direction, 
 the hydraulic circuit further comprises a coupling, called a priming coupling, which forms a water inlet into the hydraulic circuit and is configured to allow the hydraulic circuit to be primed with water. 
 
     
     
         2 . The device as claimed in  claim 1 , wherein at least one suction port is provided with a flap configured for reducing the passage cross-section of said suction port in the return direction without blocking it. 
     
     
         3 . The device as claimed in  claim 1 , wherein the suction port is provided with a non-return flap provided with a reflux orifice having a passage cross-section that is smaller than the passage cross-section of the suction port in the suction direction. 
     
     
         4 . The device as claimed in  claim 3 , wherein the reflux orifice has a passage cross-section in the return direction of between one tenth and one thirtieth of the passage cross-section (Sa) in the suction direction of the suction port. 
     
     
         5 . The device as claimed in  claim 2 , wherein the flap is made of an elastomeric material. 
     
     
         6 . The device as claimed in  claim 1 , wherein said priming coupling is configured so that it can be connected to a standard domestic tap. 
     
     
         7 . The device as claimed in  claim 1 , wherein said priming coupling is mounted on an upstream pipe of the hydraulic circuit extending between a suction port of reduced passage cross-section in the return direction and the pumping device. 
     
     
         8 . The device as claimed in  claim 1 , wherein the hydraulic circuit is further equipped with at least one manual filling port in order to enable the hydraulic circuit to be primed with water manually. 
     
     
         9 . The device as claimed in  claim 1 , wherein said treatment unit is a water heating device. 
     
     
         10 . A pool equipped with at least one treatment device as claimed in  claim 1 . 
     
     
         11 . The pool as claimed in  claim 10 , further comprising a main filtration circuit comprising:
 a main water pumping device interposed in a main hydraulic circuit in order to generate therein a flow of water between at least one pool water recovery port and at least one pool water return port,   at least one main water filtration unit interposed in the main hydraulic circuit for treating the water circulating therein,   
       wherein it further comprises at least one treatment device as claimed in  claim 1  and:
 the main hydraulic circuit of the main filtration circuit is separate from the hydraulic circuit of each treatment device. 
 each recovery port of the main filtration circuit is separate from each suction port of each treatment device, and each return port of the main filtration circuit is separate from each return port of each treatment device, 
 the main pumping device of the main filtration circuit is separate from the pumping device of each treatment device, 
 the main filtration unit of the main filtration circuit is separate from the treatment unit of each treatment device.
