Method and apparatus for programably treating water in a water cooler

A water dispenser, comprising:

• a) a cabinet having upper and lower end portions;
• b) reservoir contained within the cabinet, the reservoir being capable of holding water;
• c) an anti-spill annular housing
• that is attached to the cabinet above the reservoir,
• the anti-spill annular housing having
• an interior,
• a separating wall that separates the interior from the water contained in the reservoir,
• a central opening surrounded by a bottle support surface that is configured to support an inverted water supply bottle having a neck;
• d) a male water inlet,
• the male water inlet configured to connect to the water supply bottle at the bottle neck and being fluidly connected to the reservoir;
• e) at least one spigot in fluid communication with the reservoir for dispensing water;
• f) a diffuser contained within the reservoir for emitting bubbles into the reservoir;
• characterized by:
• g) an ozone generator
• contained within the annular housing and
• being operably connected to the diffuser;
• h) a controller operably connected to the ozone generator and located in the interior of the anti-spill housing;
• i) the controller being programmable regarding the timing and the duration of ozone generated by the ozone generator and sent to the diffuser;
• j) at least one water detection probe
• operably connected to the controller at a point that is located in the interior of the anti-spill housing,
• the at least one water detection probe at least partially located outside of the interior of the anti-spill housing and
• extending downwardly into the reservoir to detect a water level within the reservoir,
• wherein the at least one water detection probe prevents operation of the ozone generator based on the water level in the reservoir.
