DEVICE FOR DISINFECTING WATER USING OZONE AND ULTRAVIOLET LIGHT
The invention relates to a device for disinfecting water of a swimming pool, comprising an inlet for water from the swimming pool, an ozonation device, and a mixing section for ozone-containing water. The ozonation device comprises at least one UV light source ( 3 ) for generating ozone and an admixing unit ( 10 ) for admixing the generated ozone to the water of the inlet. The mixing section comprises a housing ( 1 ) which is connected to the inlet, and the at least one UV light source ( 3 ) is arranged on the housing ( 1 ) or within the housing ( 1 ) so as to emit the UV light into the housing interior. The housing ( 1 ) is provided with a transparent panel ( 11 ) for visually inspecting the housing interior. According to the invention, the housing ( 1 ) forms deflecting surfaces ( 2 ) for the water, said surfaces protruding into the housing interior and ensuring a meandering flow within the housing ( 1 ). The device according to the invention allows an improved disinfection and can be designed so as to be space-saving and more visually pleasing than conventional devices. Encasements ( 5 ) of successive UV light sources ( 3 ) are connected to one another via an air flow channel ( 8 ).
1 . A device for disinfecting water of a swimming pool, comprising an inlet for water from the swimming pool, an ozonation device, and a mixing section for ozone-containing water, wherein the ozonation device comprises at least one UV light source ( 3 ) for generating ozone, and an admixing unit ( 10 ) for admixing the generated ozone to the water of the inlet, and the mixing section comprises a housing ( 1 ) which is connected to the inlet, wherein the at least one UV light source ( 3 ) is arranged on the housing ( 1 ) or within the housing ( 1 ) so as to emit UV light directed into the housing interior, and the housing ( 1 ) is provided with a transparent panel ( 11 ) for visually inspecting the housing interior, characterized in that the housing ( 1 ) forms deflecting surfaces ( 2 ) for the water, said surfaces protruding into the housing interior and ensuring a meandering flow within the housing ( 1 ).
2 . A device according to claim 1 , characterized in that the at least one UV light source ( 3 ) which is arranged within the housing ( 1 ) comprises a casing ( 5 ) which is arranged on a deflecting surface ( 2 ) or forms a portion of the deflecting surface ( 2 ).
3 . A device according to claim 2 , characterized in that a sequence of deflecting surfaces ( 2 ) which are arranged in parallel and are each provided with a UV light source ( 3 ) is provided within the housing ( 1 ).
4 . A device according to claim 3 , characterized in that the casings ( 5 ) of successive UV light sources ( 3 ) are connected to each other via an air flow channel ( 8 ), and the housing ( 1 ) comprises an intake opening ( 6 ) for air and a discharge opening ( 9 ) which is connected to the admixing unit ( 10 ).
5 . A device according to one of the claims 2 to 4 , characterized in that the casing ( 5 ) of the at least one UV light source ( 3 ) which is arranged within the housing ( 1 ) is arranged in a water-proof manner within the housing ( 1 ), and the UV light source ( 3 ) is exchangeably arranged within the casing ( 5 ).
6 . A device according to one of the claims 1 to 5 , characterized in that the housing ( 1 ) is formed in a mirrored manner in the direction of the transparent panel ( 11 ) at least on the side opposite the transparent panel ( 11 ).
7 . A device according to one of the claims 1 to 6 , characterized in that a swirling plate ( 7 ) is arranged within the housing ( 1 ), said swirling plate crossing the water flow formed by the deflecting surfaces ( 2 ) and being provided with water passage openings in the crossing regions.
8 . A swimming pool with a device for the disinfection of water of the swimming pool according to one of the claims 1 to 7 .
