PURPOSE:To make easy and quick piping work without damaging the outer appearance of a building by disposing drain pipes for an air-conditioner along gaps among pillars and walls, and holding lower portions of the drain pipes on the pillars in a state where they are bundled to be further extendable by a predetermined length than lower ends of the gaps among the pillars and walls. CONSTITUTION:An indoor air conditioner 1 of an air conditioner is mounted on a second floor unit 20, through a pillar of which unit 20 a first hole 8 is formed for leading a drain pipe 4 into the pillar. Likewise, a second hole 13 is formed through a pillar 12 of a first floor unit for leading the drain pipe 4 led into the pillar to the outside of the same. The drain pipe 4 includes one end on the upper side thereof connected to a joint 5 and the other end disposed downwardly along the inner surface 9 of the pillar 21 through the first hole 8. The drain pipe 4 is bundled at the lower side thereof so as to be further extendable by a predetermined lengths than the lower end of the pillar 21 and held in a hollow part in the pillar 21. More specifically, the drain pipe 4 is bundled, having its length which at least allows the pipe 4 extends to an indoor feeding drain pipe 30. Further, a weight W is mounted, as required, at the lower end of the drain pipe 4. |
