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. |
