A combination water and coffee dispenser includes a hollow housing having an interior chamber. A water supply line extends from a domestic water source into the interior chamber for supplying fresh water to a cold water storage tank, a hot water storage tank and possibly to a raw water dispensing nozzle on the exterior of the housing. A liquid coffee concentrate storage container is received within the interior chamber and is in liquid communication with a pump. A discharge tube extends from the pump to a mixing chamber. Hot water is routed from the hot water storage tank to the mixing chamber wherein the hot water is mixed with liquid coffee concentrate to produce coffee having a predetermined concentration. The pump speed and thus the concentration of coffee produced in the mixing chamber is controlled by a potentiometer. The device is also equipped with a chilled compartment for storing refrigerated liquid coffee concentrate formulations.

What is claimed is: 1. A combination water and coffee dispenser comprising: a hollow housing having at least one exterior wall and an interior chamber; a chilled water storage tank received within said interior chamber, said chilled water storage tank in fluid communication with an external water source; a heated water storage tank received within the housing interior chamber, said heated water storage tank in fluid communication with an external water source; a liquid coffee concentrate storage container received within said housing interior chamber; said container having liquid coffee concentrate stored therein; a mixing chamber received within said interior chamber, said mixing chamber in fluid communication with said heated storage tank and said liquid coffee concentrate storage container whereby hot water and liquid coffee concentrate are mixed therein to produce coffee having a desired concentration; means for automatically delivering coffee concentrate from said liquid coffee storage container to said mixing chamber; means for priming and flushing said means for automatically delivering coffee concentrate from said liquid coffee storage container to said mixing chamber; a chilled coffee storage compartment received within the interior chamber of said housing for storing containers of unstable liquid coffee concentrate, said chilled water storage tank includes an outer wall with a substantial portion encapsulated by an insulating skirt with a portion of said skirt extending a predetermined distance beyond the chilled water tank outer wall forming a space therebetween, said space defining said chilled coffee storage compartment. 2. The combination according to claim 1 further comprising a supply line routed from a domestic water source to said heated water storage tank and said chilled water storage tank. 3. The combination according to claim 2 whereby said supply line includes a filter for removing contaminants from said domestic water source. 4. The combination according to claim 1 wherein said means for automatically delivering coffee concentrate from said liquid coffee storage container to said mixing chamber comprises a pump received within said interior chamber, said pump in fluid communication with said liquid coffee concentrate storage container and said mixing chamber for automatically delivering coffee concentrate from said liquid coffee storage container to said mixing chamber. 5. The combination according to claim 4 further comprising a potentiometer electrically connected to said pump for varying the speed of said pump to modify the concentration of coffee produced in said mixing chamber. 6. The combination according to claim 5 further comprising a first switch means for activating said pump. 7. The combination according to claim 6 wherein said means for priming and flushing said means for automatically delivering coffee concentrate from said liquid coffee storage container to said mixing chamber comprises a second switch means for bypassing said potentiometer whereby said pump operates at a maximum operating speed for priming and flushing.
