Abstract

The invention discloses a drainage impeller and a drainage pump set therewith, and a washing machine. The drainage impeller comprises: a wheel disc, the wheel disc being at least partially formed as a guiding section, and the cross-sectional area of ​​the guiding section in a direction away from the bottom surface of the roulette Gradually decreasing; a plurality of blades, the plurality of blades having the same shape and circumferentially disposed on the wheel; the front end of the blade being adjacent to the center of the wheel, the trailing end of the blade being adjacent to the edge of the wheel, at the front end of the blade to the trailing end of the blade In the direction, the blade is bent in the rotation direction of the drainage impeller; the lower edge of the blade is fixed to the guiding section, and the upper edge of the blade is offset from the lower edge, and the direction of the deviation is consistent with the bending direction of the blade. According to the drain impeller of the present invention, the flow guiding effect of the drain impeller can be increased, and the drainage flow rate of the drain impeller can be increased.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a drainage impeller, a drainage pump set with the same, and a washing machine. Background technique [0002] The motor of the drain pump set for washing machine in the related art usually adds a starting chamber between the motor shaft and the drain impeller to increase the output torque to drive the drain impeller to rotate. Before the motor drives the drainage impeller to rotate, the motor shaft repeatedly rotates in the forward and reverse directions in the starting chamber to generate noise, which affects the comfort of the user. At the same time, in order to make the flow of the drainage pump equal when the motor rotates forward and reverse, the blades of the drainage impeller are straight, so that the lift of the drainage pump set is low and the drainage flow is small. Contents of the invention [0003] The present invention aims to solve at least one of th...
