PURPOSE:To discharge drain water, even if a clearance between a ceiling and a floor slab is narrow or even if a distance between an air-conditioner and a pipe shaft is long, by forcibly feeding the drain water from the air-conditioner, using a pump. CONSTITUTION:When the amount of drain water reaches the level of an electrode (d) in a drain tank 16, a pump 17 is automatically started by output from a waterlevel sensor 24 and the drain water is forcibly fed to a flexible tube 20 through a solenoid valve 18 and a check valve 19. Therefore, the drain water fed to the flexible tube 20 is sent from a flange part 33 on a connection pipe 31 to a drain outlet 39, flows together with dirty water, miscellaneous discharge water, rainwater or other drain water through a flowing-down passage 38, and is effectively discharged. |
