ENCLOSED COOL-WATER TANK AND COOL-WATER, PURIFING WATER SYSTEM

摘要

PURPOSE: A closed type cold water tank capable of preventing contamination and a cold water purification system using the same are provided to prevent contamination of water by blocking the invasion of small bugs from the outside of the water tank, and have clean drinking water by removing the pollution source which is generated inside the water tank and moving to the clean water outlet. CONSTITUTION: A closed type cold water tank comprises an inlet port in which the clean water is flowed in; and an inside body in which the vent to discharge the cold water is formed integrally; a first housing which is comprised with the inner cap which forms a first screw hole in top, and inserted to the inside body and tightened with the heat sealing or the rotation fusion; a water tank which stores the clean water which is flowed in through a conduit line which is connected in the inlet port and which is accommodated in the first housing; a stopper part in which the screw part corresponding to first screw hole is formed on outer side surface; a refrigerant pipe which changes the clean water of the water tank to the cold water with the refrigerant circulation by being fixed to the stopper part; an external body which surrounds the inside body by forming a penetration hole respectively in the bottom surface in order to penetrate the inlet port and vent; and inserted and tightened in the external body with the heat sealing or the rotation fusion; a second housing which comprises the outer cap in which the second screw hole corresponding to the screw part is combined in the stopper part is formed.
