PROBLEM TO BE SOLVED: To provide a drainage device capable of preventing backflow of drain water and entering of dust from the outside.SOLUTION: A drainage device 1 includes: a top plate part; and a side wall part formed along an outer periphery of the top plate part at one side of the top plate part. The side wall part includes: an opening penetrating the side wall part and draining drain water from a bottom of a casing 110 to a draining port 113; and a valve for opening/closing the opening. Further, the valve includes: a shaft member provided on the side wall part above the opening; a tabular valve body whose upper end is swingably supported by the shaft member, and which is formed to be a size of covering the opening when swinging to the opening side; an inclined surface being formed on the side wall part, inclined to a draining port 113 side as it goes toward the bottom of the casing 110 from a lower part of the shaft member, and receiving the tabular valve body when the tabular valve body swings to the opening side; and a packing being provided on the opening side of the tabular valve body, and coming into close contact with the inclined surface on a peripheral edge of the opening when the tabular valve body is received by the inclined surface.SELECTED DRAWING: Figure 1
【課題】ドレン水の逆流と外部からの粉塵の進入とを防止できるドレン排水装置を提供する。【解決手段】ドレン排水装置1は、天板部と、天板部の片面側で天板部の外周に沿って形成される側壁部と、を備える。側壁部は、側壁部を貫通し、ケーシング110の底からドレン排水口113へドレン水を排水する開口部と、開口部を開閉する弁と、を有する。また、弁は、開口部よりも上の、側壁部に設けられた軸部材と、軸部材に上端が揺動可能に支持され、開口部側に揺動した場合に開口部を覆う大きさに形成された板状の弁体と、側壁部に形成され、軸部材の下からケーシング110の底に向かうに従いドレン排水口113側へ傾斜し、板状の弁体が開口部側に揺動した場合に板状の弁体を受け止める傾斜面と、板状の弁体の、開口部側の面に設けられ、板状の弁体が傾斜面に受け止められた場合に開口部の周縁で傾斜面に密着するパッキンと、を有する。【選択図】図1
