Patent ID: 7740027

Claim:
Apparatus for applying chemicals to water in an air conditioning condensate tray, the apparatus comprising: an elongate reservoir body having an open upper end, a closed lower end, and a central cavity enclosed by an encircling wall, the central cavity constructed to receive chemicals; a top closure removably connected to the upper end for closing the open upper end of the central cavity; no more than one aperture in the encircling wall; a tubular member operatively connected at a first end to the one aperture and having a second end extending outwardly therefrom; the second end constructed for receiving condensate water from the condensate tray for providing a fluid passage for the water to the central cavity in a first mode of operation when water in the condensate tray is above a preset level; and the second end further constructed for dispensing water from the central cavity in a second mode of operation with chemicals disposed in the water from contact within the central cavity when water in the condensate tray is below a preset level.
