DRAIN HOSE FOR SEPARATE TYPE AIR-CONDITIONER

摘要

PROBLEM TO BE SOLVED: To contribute to efficient installation work of an air-conditioner by forming a drain path around an electric wiring path formed at the hollow part of a drain hose. SOLUTION: A tubular passage 131 of liquidtight structure is arranged along the central part in the hose body 130 while being supported by a plurality of supporting parts 132 extending radially and a drain path 133 is formed around the passage 131 thus obtaining an integrally molded drain hose 13. A control signal is delivered from an indoor unit through an electric wiring 14 in the passage 131 arranged in the center of the hose body 130 to an outdoor unit and drain is discharged from the indoor unit through the drain path 133 to the outside. Since only the coolant tube and the drain hose 13 is required to be routed at the time of installing an air-conditioner, installation work is simplified.
