Method and apparatus for programably treating water in a water cooler

A water dispenser, comprising:

• (a) a cabinet having a reservoir contained within the cabinet, the reservoir being capable of holding water, and at least one spigot in fluid communication with the reservoir for dispensing water;
• (b) 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;
• (c) 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;
• (d) a diffuser contained within the reservoir for emitting bubbles into the reservoir;
• characterized by:
• (e) an ozone generator
• contained within the annular housing and
• being operably connected to the diffuser;
• (f) a controller operably connected to the ozone generator, the controller being programmable regarding the timing and the duration of ozone generated by the ozone generator and sent to the diffuser;
• (g) 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.
