WATER SUPPLY SYSTEM

PROBLEM TO BE SOLVED: To eliminate temperature rising of water in a connection pipe, and to eliminate dew condensation in a connection pipe periphery and a water supply pipe periphery in regard to a water supply system. SOLUTION: A water storage tank 11 is arranged in an inner side of a door 10 of a refrigerator body 9, and the water supply system is composed of the connection pipe 13 moving water stored in the water storage tank 11 to the outside of the door 10 of the refrigerator body 9, having one end connected to the water storage tank 11 and another end arranged outside the door 10, and composed by a heat insulating member, an opening and closing device 14 connected to the other end of the connection pipe 13, a water supply pipe 15 connected to the opening and closing device 14, and a water supply lever 16 carrying out opening and closing of the opening and closing device 14. By this, water in the connection pipe 13 and outside air are thermally insulated, temperature rising of the water in the connection pipe 13 is eliminated, and dew condensation in the connection pipe 13 periphery and the water supply pipe 15 periphery can be eliminated.
