The inventor of the washing machine was American hamilton smith. He made the world's first washing machine in Pittsburgh. This washing machine has only one main part. The barrel is equipped with a belt-shaped straight shaft, and then the crank connected with the straight shaft is shaken to rotate. This is a manual washing machine. Although this is the 1 washing machine, it has not been widely used because it needs manual rotation. Next, Bian Xiao will give you a detailed introduction to the development of washing machines.
In addition to the above-mentioned hamilton smith made the first washing machine in the world, 1874, American Bill Black invented the wooden manual washing machine. Although it is not so convenient, on the basis of the previous washing machine, the invention of this washing machine is one step closer to our present washing machine. Then in 1880, the United States invented the steam washing machine, which made our life more convenient than before. Then in 19 10, Fisher of the United States invented the world's first electric washing machine, which is very close to the automatic washing machine we use today. Then, after several generations of inventions, Japan developed various washing machines on the basis of 1955 British jet washing machine, such as pulsator, drum type, stirring type and so on. Up to now, our automatic washing machine doesn't need us to wash it by hand at all. Turn on the washing machine, then plug it in, pour the washing powder in, and throw the clothes in, as long as we take it out to dry every once in a while.
I have to say that the washing machine is really a great invention, because it makes our household affairs an automatic process, and it can save us a lot of time without washing clothes manually.
