To provide a drainage vane that can effectively improve the drainage efficiency of a drainage motor.SOLUTION: A drainage vane 10 includes a concave disc body 11 and a shaft. The concave disc body has a disc 13 and a ring-shaped wall surface 15. The shaft extends through the disc with a certain distance from the disc, and divided into an upper shaft part and a lower shaft part 25. The upper shaft part is disposed above the disc and has plural supporting ribs 27 extending outwardly along a radial direction. The plural supporting ribs are coupled to the concave disc body. The lower shaft part is a polygonal column body disposed below the disc. The polygonal column body has plural side wall surfaces 261 and a bottom surface 263 corresponding to a cross section of the polygonal column body. The plural side wall surfaces have elongated corner surfaces 265 each formed by combining two adjacent edges with each other. The polygonal column body is twisted from the bottom surface at a certain angle with respect to the disc, slanting the plural side wall surfaces and the plural corner surfaces.SELECTED DRAWING: Figure 2
【課題】排水モーターの排水効率を効果的に向上させることができる排水羽根を提供する。【解決手段】排水羽根１０は凹状円盤体１１およびシャフトを備える。凹状円盤体は円盤１３および環状壁面１５を有する。シャフトは円盤と一定距離を保ちながら円盤を貫通し、軸上部および軸下部２５に分けられる。軸上部は円盤の上方に位置し、複数の径方向に沿って外側へ伸びていく支持リブ２７を有する。複数の支持リブは凹状円盤体に連結される。軸下部は円盤の下方に位置する多辺形柱体である。多辺形柱体は複数の側壁面２６１と、多辺形柱体の断面に対応する底面２６３とを有する。複数の側壁面は二つずつ隣り合う辺縁部が相互に連結されて形成した細長い角面２６５を有する。多辺形柱体は円盤に対して底面から一定角度に至るまで捻じれ、複数の側壁面および複数の角面を傾斜させる。【選択図】図２
