[0002] Pulsator washing machines are the most popular washing machines on the market. They are easy to use, simple in structure and inexpensive. The washing agitation is achieved by the rotation of the impeller disc set at the bottom of the washing drum.

However, in the actual use of the pulsator washing machine, the clothes are easily entangled with each other when tumbling in the inner drum because the vortex driven by the impeller is too single, which will not only cause the center of gravity of the inner drum to shift, but also increase the chance of wear and tear on the clothes.
