Housework is no longer heavy.

1906 invention of washing machine The first electric washing machine in the world was designed and manufactured by Fisher in Chicago, USA on 1906. In later years, the functions of washing machines were gradually strengthened and improved, and the history of the development of washing machines was also a history in which women were gradually liberated from heavy housework.

Nowadays, in some villages, we occasionally see some women beating their clothes with wooden sticks by the river. This primitive way of washing clothes lasted at least thousands of years. The birth of washing machine really liberated women from heavy housework.

The original washing machines were all made of wood. You need to turn the handle manually, and it takes a lot of time to rinse clothes. For example, in 1874, Bill blackstone of the United States invented a wooden hand washing machine. Six blades were installed at the bottom of a bucket, and the clothes were constantly turned and rubbed in the bucket through the drive of a handle and a gear mechanism, thus achieving the purpose of washing clothes.

1880, the United States made a steam-driven washing machine, which was powered by steam instead of manual shaking handle. Later, hydraulic washing machines, hand washing machines and washing machines driven by gasoline engines appeared one after another. Electricity was invented, and electric washing machines were finally born.

1906, American Chicago Fisher designed and manufactured the world's first electric washing machine. On the basis of the original washing machine, Fisher designed such a device: an engine drives a horizontal drum. This new device greatly reduces manpower.

Later, an American company changed the bucket of washing machine into a cast aluminum bucket, which improved the mechanical strength and service life. Another company in new york has also made an electric washing machine and dryer. When washing clothes, tilt the bucket 45 degrees to match a slow-rotating gear, then lift the bucket full of wet clothes and put it vertically on another fast-rotating transmission shaft to spin the water dry.

In the forties and fifties, automatic washing machines with electric water heaters and pumps, as well as drum dryers came out one after another.

With the development of modern electronic industry, from manual and semi-automatic washing machines to computer-controlled full-automatic washing and drying machines, the soaking, washing, washing and drying of clothes are all controlled by electronic timing switches and sensors for monitoring speed and temperature. When clothes are put in, they can be operated automatically, regardless.

In 1990s, Matsushita Electric Co., Ltd. of Japan developed an automatic washing machine with fuzzy control theory. Its characteristic is that no matter how much clothes are, the washing time can be automatically selected according to the degree of dirty clothes.

An ozone technology company in Florida, USA, pioneered new ideas and successfully developed a new ozone washing machine. Use cold water, no detergent, just 10 minutes. The ozone in this washing machine can remove all organic pollutants and then filter out the pollutants in the washing water. Therefore, this kind of water can be recycled repeatedly. This washing machine can remove 95% dirt from clothes.
