Abstract
A swimming pool water sanitizing unit with an ozone generator and a separate ultraviolet (UV) reactor chamber within the same housing unit. The ozone generator may include a water jacket gap between the ozone generator chamber and the outer casing that passes pool water through the gap for cooling. Either of the ozone generator and the UV reactor chamber may include UV intensity sensors to help predict the life of the UV bulb therein. The UV reactor chamber may include rotating water paddle blades to stir up the water within the chamber for enhanced exposure to the UV light. A diverter valve enables diversion of ozone enriched fluid to the pool pump in addition to the UV reactor chamber.

A swimming pool water sanitizing unit comprising:
- a pool water inlet and a pool water outlet extending from a sanitizing unit housing;
- a sanitizing unit control center on or within the sanitizing unit housing;
- an ozone generator within the sanitizing unit housing and comprising an outer casing, an ozone generator chamber configured to receive a first ultraviolet (UV) light source within the ozone generator chamber and to generate ozone enriched fluid and output the ozone enriched fluid through an ozone output of the ozone generator chamber, the ozone generator chamber surrounded by a plurality of heat sink fins extending from the ozone generator chamber, and a water jacket gap between the ozone generator chamber and the outer casing, the water jacket gap fluidly coupled to both an ozone generator water inlet and an ozone generator water outlet, the ozone generator chamber further comprising a first UV intensity sensor within the ozone generator chamber, the first UV intensity sensor configured to send first UV intensity data to the sanitizing unit control center to indicate when the first UV light source drops below a predetermined first UV intensity level as measured at the first UV intensity sensor;
- an UV reactor chamber within the sanitizing unit housing and configured to receive and enclose a second UV light source within the UV reactor chamber, the UV reactor chamber fluidly coupled to both an UV reactor chamber water inlet and an UV reactor chamber water outlet such that fluid flowing through the UV reactor chamber from the UV reactor chamber water inlet to the UV reactor chamber water outlet passes by the second UV light source when the second UV light source is received in the UV reactor chamber, the UV reactor chamber further comprising a second UV intensity sensor within the UV reactor chamber, the second UV intensity sensor configured to send second UV intensity data to the sanitizing unit control center to indicate when the second UV light source drops below a predetermined second UV intensity level as measured at the second UV intensity sensor, the UV reactor chamber further comprising a plurality of water paddle blades extending radially about an axial center of the UV reactor chamber adjacent the UV reactor chamber water inlet and configured to rotate about the axial center of the UV reactor chamber;
- an ozone injector within the sanitizing unit housing and fluidly coupled to the ozone output of the ozone generator and to the UV reactor chamber water inlet;
- and
- a diverter valve fluidly coupled to the ozone output of the ozone generator and an ozone system output, the diverter valve adjustable to regulate an amount of the ozone enriched fluid diverted from the ozone generator to a suction side of a swimming pool pump.
