PROBLEM TO BE SOLVED: To collectively discharge drain water from a plurality of discharge hole by one discharging pipe.SOLUTION: A plurality of discharge holes 10 for discharging drain water are formed in a bottom plate 4 on which a heat exchanger is mounted. Forming positions of the respective discharge holes 10 are gradually lowered. Drain caps 20 are fitted into the discharge holes 10. The drain caps themselves 20 are coupled and a water discharging pipe 21 is connected to the most downstream drain cap 20. A water discharge channel connecting the plurality of discharge holes 10 and the water discharge pipe 21 is formed by the plurality of drain caps 20. |
