Method and apparatus for programably treating water in a water cooler

A water dispenser, comprising:

• a) a cabinet having upper and lower end portions and an interior;
• b) reservoir contained within the cabinet, the reservoir having an open top and being capable of holding water;
• c) an annular, hollowed housing that is attached to the cabinet above the reservoir, said housing having an interior and a lower panel including a central opening;
• d) a flow line that supplies water to the reservoir, said flow line supported in part by the housing, the flow line having a discharge that is positioned to discharge water into the reservoir top via the housing central opening;
• 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;
• g) an ozone generator housed within said annular, hollowed housing;
• h) a flow line that enables the transmission of ozone from the ozone generator to the diffuser;
• i) a controller inside said annular housing and operably connected to the ozone generator;
• and
• j) the controller being programmable regarding multiple water dispenser functions, the functions including at least the timing and duration of ozone generated by the ozone generator that is sent to the diffuser, and
• k) further comprising multiple probes that extend from the housing into the reservoir, said probes indicating when the reservoir contains water.
