1858, American hamilton smith made the world's first washing machine in Pittsburgh. The main part of the washing machine is a circular barrel with a straight shaft and blades in it, which is rotated by shaking a crank connected to the straight shaft. In the same year, Smith obtained the patent right of this washing machine. However, this kind of washing machine has not been widely used because of its laborious use, but it marks the beginning of machine washing.
Household washing machines are mainly composed of box, washing and dewatering barrels (some are separated), transmission and control systems, and some are equipped with heating devices. Washing machines generally use water as the main cleaning liquid, which is different from using special cleaning liquid and dry cleaning which is usually handled by special personnel.

Working principle of washing machine
1, drum washing machine
The drum washing machine originated in Europe, and the washing method is designed by imitating the principle that a hammer beats clothes. The drum is driven by the mechanical work of the motor to rotate, and the clothes are constantly raised and lowered in the drum, then raised and lowered, and repeatedly moved. In addition, washing powder works with water to make clothes clean. The pulsator washing machine needs water to float the clothes, and then it is constantly stirred and rubbed to achieve the purpose of cleaning.
2. Washing machine without cleaning impeller
No cleaning, completely using physical means and intelligent cleaning. The "smart ball" used for cleaning work is made of antibacterial polymer rubber and will not be polluted when washing. The cleaning-free working process is carried out in a physical way, which will not cause damage to the washing machine and clothes.
When washing clothes, the wisdom ball pops up from the recovery cabin, and with the movement of the inner tub of the washing machine, it bounces off the inner and outer tub walls and stains without dead ends through high-frequency physical movement; When draining water, the wisdom ball returns to the recovery cabin with the drop of water level, waiting for the next use.
