ABSTRACT:
A self-filling bottled-water cooler dispenses pure water from a transparent water bottle mounted on the top of a free-standing cabinet body. The cooler attaches to a tap-water or other continuous water source and provides a continuous supply of pure water without need to change the water bottle The free-standing cabinet body includes a water tank located within the upper portion of the cabinet body and at least one tap for dispensing water from the water tank. The water bottle is securely attached on the top of the cabinet body to the water tank such that water freely flows between the bottle and the tank. Water from the tap water or other source is purified in a reverse osmosis, carbon block or other water purifier and is routed to the water tank. An inlet valve connected to a float mechanism within the water bottle regulates the flow of purified water into the water tank. The fload mechanism closes the inlet valve only when the purified water in the water bottle is at or above a desired full level. A venting system prevents overfilling of the water bottle and a change in air pressure within the bottle whenever the level of purified water in the bottle changes.
