The drum washing machine imitates the principle of hitting clothes with the mallet and is controlled by the mechanization program. When the drum rotates, centrifugal force generates, which drives detergent and water to clean clothes.
There will be a circular pulsator at the bottom of the washing machine. Driven by the wheel, the water in the bucket rotates left and right to form an eddy current, which drives the clothes inside the washing machine to rotate and roll, and remove the stains on the clothes.
