12. Principle of washing in agitator washing machines:
Answer: When the agitator rotates in both directions under the drive of the motor, the washing liquid inside the drum experiences horizontal and vertical forces. Due to friction between the washing liquid and clothes and between the drum wall and clothes, the direction and magnitude of these forces change continuously, generating two vortices horizontally and vertically. Near the agitator, the vortex is stronger, while around the bucket walls, the vortex is gentler. Their combined effect creates strong turbulence of clothes inside the drum, resulting in friction and impact between clothes themselves and between clothes and the drum wall. This repeated mechanical motion simulates hand-washing effects like rubbing and beating, achieving cleaning purposes.
