Question 2: Who invented the washing machine? 1874, the "era of hand washing" is facing unprecedented challenges. Black invented the wooden hand washing machine 1880, and the steam washing machine appeared in the United States, and steam power began to replace manpower. 19 10, Fisher Company of the United States successfully trial-produced the world's first electric washing machine in Chicago. The appearance of electric washing machine marks the beginning of human housework automation. 1922, Matayiger Company of the United States reformed the washing structure of the washing machine, changing the drag type into the stirring type, so that the structure of the washing machine was fixed, and this was the birth of the first stirring washing machine. 1932, Bendex Airlines announced that they had successfully developed the first front drum washing machine, in which washing, rinsing and dehydration were completed in the same drum. This means that the type of electric washing machine has jumped to a new level and taken a big step towards automation!
Question 3: Which country invented the washing machine? United States of America
This is the history of washing machines.
From ancient times to the present, washing clothes is an inevitable housework. Before the washing machine appeared, for many people, it was not as full of fun as described in pastoral poems. These repetitive simple manual labor often leave people with the feeling of hard work.
1874, the "hand washing era" was challenged as never before ―― someone invented a wooden hand washer. Inventor is American Bill? Black people. The structure of Blake's washing machine is very simple, that is, six blades are installed in a barrel, which is driven by a handle and a gear to turn clothes over in the barrel, thus achieving the purpose of "washing clothes". The appearance of this device greatly encouraged people who are trying to improve their living efficiency, and the improvement process of washing machines began to be greatly accelerated.
1880, steam washing machines appeared in the United States, and steam power began to replace manpower.
After that, hydraulic washing machines and internal combustion engine washing machines also appeared one after another. By 19 1 1, the United States has successfully trial-produced the world's first electric washing machine. The appearance of electric washing machine marks the beginning of human housework automation.
After several improvements, the electric washing machine ushered in a brand-new washing method "mixing" at 1922. The stirring washing machine was successfully developed by Maytag Company in the United States. This washing machine is equipped with a vertical shaft in the center of the drum and a stirring wing at the lower end of the vertical shaft. The motor drives the vertical shaft to swing back and forth periodically, so that clothes and water are constantly rolling and rubbing, thus washing away dirt. The invention has scientific and reasonable structure and is widely welcomed by people. However, after 10 years, Bendex Airlines announced that they had successfully developed the first front drum washing machine, in which washing, rinsing and dehydration were completed in the same drum. This means that the type of electric washing machine has jumped to a new level and taken a big step towards automation! Until today, drum washing machines are still widely used in European and American countries.
With the acceleration of industrialization, countries all over the world have also accelerated the development of washing machines. First of all, the jet washing machine was developed and introduced from Britain. It relies on the powerful vortex generated by the impeller running on one side of the drum to make the clothes and washing liquid roll constantly in the drum to wash the clothes. 1955, Japan developed a unique pulsator washing machine based on the introduction of jet washing machine from Britain, which has been popular ever since. At this point, the situation that pulsator, drum and stirring are divided into three parts in the production field of washing machines has initially taken shape.
After the 1960s, washing machines began to form a series in the consumer market of some developed countries, and the household penetration rate rose rapidly. The development of washing machines in Japan has attracted much attention. In 1960s, a double-barrel washing machine with a dry barrel appeared in Japan, which was called "semi-automatic washing machine". In the 1970s, a fully automatic pulsator washing machine was produced. At the end of 1970s, the automatic washing machine controlled by microcomputer was born, which was refreshing. In the 1980s, the application of "fuzzy control" made the washing machine easier to operate, more perfect in function, more convenient in washing procedure and more fashionable in appearance ... In the 1990s, due to the improvement of motor speed regulation technology, the washing machine realized a wide range of speed conversion and adjustment, and many new water washing machines were born. Since then, with the development and perfection of motor-driven technology, Japan has produced a motor-driven washing machine, canceling gear transmission and speed change mechanism, which has triggered a huge revolution in the driving mode of washing machines.
In China, due to historical reasons, the washing machine industry started late, and it was not until 1978 that household washing machines were officially produced. However, with the development of people's understanding, especially the deepening of reform and opening up, the washing machine industry has not stopped as some people expected, but has maintained a vigorous development momentum. 1983, the output of washing machines soared from 400 in 1978 to 3.65 million. Since then, a large-scale upsurge of technology introduction has been set off all over the country. About 40 manufacturers have introduced more than 60 technologies from advanced countries such as Japan, Britain, France, Italy and Australia. The introduction, absorption and innovation of technology have greatly improved the industrial quality and production capacity of domestic washing machines and shortened the gap with developed countries. Today, the annual output of washing machines in China accounts for about a quarter of the world's annual output, ranking first in the world. In addition to meeting the domestic market in quantity and variety, it is also exported to North America, Europe, Southeast Asia and other places, ranking among the top competitors in the international washing machine market ...
Question 4: Who is the inventor of TV refrigerator, washing machine and air conditioner? Refrigerator: Domelre, which was born in Chicago in 2003, was the first one. It is widely said that Swedish engineers Balser von Plantan and Karl Mont took the lead in making the first refrigerator and sold the patent right to the American company Ronghua Company. However, they invented the refrigerator in 192 1, 1923, 1926 respectively.
Washing machine: Hamilton? Smith, the inventor of washing machine. 1858, Hamilton? Smith made the world's first washing machine in Pittsburgh, USA.
Air conditioning: American inventor Willis? Haviland? Carrier designed and installed the first air conditioning system in 1902. The air conditioning system was designed for a printer in new york, USA. He found that the change of temperature would cause the deformation of paper, which would lead to the imbalance of color ink. Carrier registered the patent 1906.

Question 7: Is the washing machine the greatest invention in the world? Yes, it is called the greatest invention, because it effectively frees women's time to do housework and more time to engage in social work, and has made great contributions to promoting women's social status and equality between men and women.
Question 8: How was the washing machine invented? From ancient times to the present, washing clothes is an inevitable housework. Before the washing machine appeared, for many people, it was not as full of fun as described in pastoral poems. These simple manual labors, which are repeated repeatedly, often leave people with a hard feeling.

Jet washing machine, double-barrel semi-automatic washing machine, pulsator barrel automatic washing machine ... appeared one after another. I believe that in the near future, there will be more changes in washing machines, which will bring more convenience to our lives.
1858, American Smith made the first washing machine in the world.
The main part of the washing machine is a drum with a straight shaft with blades. Shake the crank connected to the shaft and the shaft will turn. In the same year, Smith obtained the patent right of this washing machine. This kind of washing machine is laborious to use and damages clothes, so it is not popular, but it marks the beginning of washing clothes with machines.
The following year, a washing machine with a pestle as a stirrer appeared in Germany. When the pestle moves up and down, the wooden nail with spring constantly acts on the clothes. At the end of 0/9, the washing machine was developed again. The octagonal washing cylinder is rotated by the handle, and hot soapy water is put into the cylinder when washing. After washing clothes, squeeze them dry with a liquid roller.
The first electric washing machine was made in Chicago in 19 10 by Fisher of the United States. However, after this electric washing machine entered the market, the sales volume was not good. The washing machine was really accepted by people after the First World War.
1922, Snyder of the United States invented the stirring electric washing machine, which was mass-produced in Iowa, USA. This washing machine was welcomed by people as soon as it was put into the market because of its greatly improved performance. The following year, a German manufacturer also produced a washing machine heated by a coal stove. This washing machine has a container with a small hole. After clothes are put in, the shaft connected with the container is driven by the motor, so that the container moves forward and backward continuously. 1937 the first automatic washing machine came out. This is a front automatic washing machine. The washing tub is driven by a horizontal shaft and can hold 4000 grams of clothes. Clothes keep rolling up and down in a sink filled with water to purify and remove dirt. In the 1940s, a modern overhead automatic washing machine appeared.
Question 9: The inventor of washing machine? Fisher, R.
Ronald Aylmer Fisher (1890~ 1962)
British statistician and geneticist. 1890 was born in London in February of 17, and 1962 died in Adelaide, Australia on July 29th. 19 12 graduated from the mathematics department of Cambridge university and studied statistical mechanics with British mathematical statistician J. Jones for one year. He used to be a middle school math teacher, 19 18 years, and the director of the statistical laboratory of Rottenstein Agricultural Experimental Station. 1933, because of his outstanding achievements in biostatistics and genetics research, was hired as a professor of eugenics at London University. Professor of Genetics, Cambridge University. 1957 retired. From 65438 to 0959, he went to Australia to do research work in the Department of Mathematical Statistics of the Federal Scientific and Industrial Research Organization.
His main contributions are as follows: ① The correlation of kinship shows that the traits of continuous variation can be explained by Mendel's law, thus solving the debate between Mendel school and biostatistics school in genetics. ② The principle and method of variance analysis are demonstrated and applied to experimental design. This paper expounds the maximum likelihood method and the theories of randomization, repeatability and statistical control, and points out the importance of freedom as a statistical table for testing K. Pearson. In addition, the sampling distribution of various correlation coefficients is expounded and the significance test is carried out. ③ Some mathematical principles and methods put forward by him have great influence on the basic concepts of human genetics, evolution and quantitative genetics, as well as experiments in agriculture and medicine. For example, the concept of heritability is based on the theory that his traits can be decomposed into additive effects, non-additive (dominant) effects and environmental effects. The main works include: genetic relationship based on Mendel's genetic model, statistical methods used by researchers, genetic theory of natural selection, experimental design, inbreeding theory, statistical methods and scientific reasoning. He is an extreme selector in evolutionary genetics and thinks that neutral traits are difficult to exist. He has made outstanding achievements in statistical biology all his life.
