Drain pump

Provided is a drain pump. Rotating blades (70) adopted by the drain pump comprise multiple plate-shaped large-diameter blades (60), which are extended towards the radial direction from a shaft part (52) in connection with an output shaft of an electric motor; multiple plate-shaped small-diameter bla...

description	Provided is a drain pump. Rotating blades (70) adopted by the drain pump comprise multiple plate-shaped large-diameter blades (60), which are extended towards the radial direction from a shaft part (52) in connection with an output shaft of an electric motor; multiple plate-shaped small-diameter blades (54), which are connected with lower edge parts of the large-diameter blades (60); and auxiliary blades (68) between the adjacent large-diameter blades (60). Step parts (72, 74, 82 and 84) are arranged at the peripheries of the large-diameter blades and the auxiliary blades to guide the water that is stirred by the blades to the outer sides of the blades. By means of the step parts, the space into which the drain water flows behind the blades is suppressed. In this way, the discharge ability is improved, while vibration and noise are suppressed. By the drain pump of the invention, improvement of the discharge ability and the mute property during operation can be realized at the same time.
