Commercially available washing machines may be roughly classified into vortex washing machines, agitated washing machines and drum washing machines according to their washing methods.

When the washing machine called agitator, which is rotatably mounted and fixed in the center of the washing machine, rotates regularly, the stirring wing formed on the side of the washing machine forms a stream of water. The laundry is washed while rubbing against the wall.

Such a washing machine is less damaging to the laundry than the vortex washing machine, the laundry is not tangled well, the washing capacity is large, but it consumes a lot of power and is suitable for washing bulky laundry due to the laundry rod formed in the center of the washing tank. Not.

Vortex washing machine is one of the most widely used method of rotating the laundry by rotating the pulsator is rotatably mounted on the lower end of the washing tank to generate a swirl-like water flow.

In addition, the drum type washing machine has a cylindrical cylindrical drum having a plurality of water holes formed horizontally in the water tank and rotates it, thereby pulling the laundry to the upper space in the drum by the projections in the drum and falling downward by gravity.
