The washing machine was invented by Americans in the middle of19th century. Specifically, it was invented by American James Moses Chet at 185 1, when he obtained a patent. Chet invented a washing machine driven by human power, which used a shaft and a horizontal paddle mounted on a box to wash clothes. Users need to shake the rotating shaft by hand to make the blades of the washing machine rotate in the water, thus washing clothes. This washing machine, called Chet Wheel, was the first machine to wash clothes with rotating shaft and horizontal paddle.
However, the washing machine was not invented by Chet first, and similar machines were invented before him. For example 1829 An Englishman Joseph Blache invented the steam-driven washing machine, but it was not widely used at that time. In addition, Samuel Moran, an American, also invented a washing machine similar to that invented by Chet in 1834, but its horizontal paddle rotates vertically.
In a word, James Moses Chet was the first inventor who patented and popularized the washing machine, but the washing machine was not his first invention.
