The water cooler has a water inlet (4) for receiving treated water from a piped drinking water supply which feeds a thermally insulated chamber (2) containing a cooling element (12) to provide a volume of cooling medium. Residual sanitizing chemicals in the water supply prevent bacterial growth within the chamber (2). Water leaves the chamber (2) via an outlet coupling (10) and enters a filter cartridge (7) which is engaged on a seat (6) incorporating a well (11). The cartridge contains a water filter (20) within a filter housing (17) which is received in the well (11) surrounded by the cooling medium. A manifold (16) in thermal contact with the seat (6), incorporates a connector (19) which sealably engages the coupling (10), flow passages, and a dispense outlet (18). The filter cartridge is cooled to ensure that cooled water can be dispensed on demand, and periodic replacement of the filter cartridge ensures that the filtration components remain sanitized. |
