Abstract:
1. A toilet bowl water purifier adapted to be mounted within a water tank of a conventional flush toilet having a standpipe in fluid communication with the toilet bowl, a flapper valve for passing water to the toilet bowl from the water tank and a water fill tube extending from a valve mechanism responsive to the water level in the water tank for filling the tank, said water purifier comprising in combination: a) a plenum for accommodating a flow of air therethrough; b) a UV lamp disposed in said plenum for irradiating air within said plenum to kill microorganisms and to selectively convert oxygen molecules into ozone molecules and produce ozone enriched air for oxidizing organic matter present in the air and to kill bacteria and viruses that may be present in the air; c) a fan for urging a flow of air through said plenum; d) a conduit interconnecting the stand pipe with said plenum, whereby said fan draws air from the toilet bowl through the stand pipe into said plenum to subject the drawn air to radiation from said UV lamp; e) a further conduit extending from said plenum downwardly to a point below the normal water level within the water tank to convey the irradiated and ozone enriched gases into the water; and f) a device for automatically sensing a flush mode of the flush toilet and for causing the purifier to be energized only during the flush mode.
