PROBLEM TO BE SOLVED: To facilitate operation of a connection portion between a drain pan and a drain pipe in a drain structure where water is drained from the laterally elongated drain water pan of an indoor machine. SOLUTION: There are provided a laterally elongated heat exchanger 2 in a frame structure 1 of an indoor machine and a laterally elongated drain water pan 3 on a lower portion of the heat exchanger 3. There are formed connection ports 4 with the same configuration as float of a drain hose on the left and right of the drain water pan 3, on each of which connection ports the drain hose can be mounted. A flexible connection port cover 5 having the configuration of a bottomed cylinder and having an outer diameter in close vicinity with an inner diameter is mounted on the one connection port 4, and a drain hose is mounted on the other connection port 4. A flange 5a larger than an outer diameter of the connection port 4 is formed along an opening edge portion of the connection port cover 5, and a center pin 5b is provided on a bottom plate of the connection port cover 5, which center pin passes through an internal space of the connection port cover 5 and extends to be taller than the flange 5a. The connection port cover 5 is mounted or demounted using the flange 5a while pushing time center pin 5b. |
