ABSTRACT:
A water transport system replaces the inverted water bottle on a conventional bottled water cooler of the type with a refrigerated, open top water reservoir. The system automatically transfers water from an upright water bottle below the reservoir into the reservoir whenever water in in the reservoir falls below a predetermined level. A water pipe carries water from the bottle, through a sealed closure in the bottle neck and up into the reservoir whenever air pressure in the bottle is elevated. An air pump in a housing atop the reservoir generates air pressure in an air tube passing through the closure and into the bottle. A water level sensor reduces air pressure in the system when the water in the reservoir reaches a predetermined level to thereby automatically control refilling of the reservoir.
