Development process of electric fan

At the time of the industrial revolution, electric fans were a great invention and important to everyone. Over time, they are improved smartly and more conveniently.

Development history of electric fans

Learn about general electric fans

Electric fans (fans) are an electric drive device and a scientific invention . They are used to create winds to serve human interests (reduce body heat, cool down, help people feel cool, comfortable), ventilation, exhaust, cooling, or any period of impact related to air in the living environment.

Electric fans are a great invention of human history

When operating, the electric fan consists of fast rotating rotors that create air currents . Manufacturers design each electric fan with varying degrees of rotation from the highest to the lowest. The operating principle of electric fans is greatly utilized in everyday life such as wind speed meters (wind meters) and wind turbines.

Some of the most typical applications include air conditioning, temperature reduction systems, human utilities (such as electric table fans), ventilation (such as exhaust fans), screening (as used for separating grain grain), remove dust (like vacuum cleaner). People often use electric fans to dry clothes, hair, scarves .

History of electric fan, air conditioner

Before electric fans were invented, people could only use paper fans

The origin of the electric fan was created according to the mechanism that works like a pull fan in the Middle East in the early 19th century . It was a system consisting of a silver fabric frame connected to a wire that pulled back and forth to create a wind flow.

After the industrial revolution in the late 19th century, hydraulic plants created a belt driven fan.One of the first fan builders was Omar-Rajeen Jumala in 1832 . He called his invention a centrifugal fan, which works like an air pump.

Ceiling fans were invented in 1882

These centrifugal fans were successfully used in factories in 1832-1834. When Thomas Alva Edison and Nikola Tesla discovered electricity for the world at the end of the nineteenth and early twentieth centuries, mechanical fans evolved into electric fans.Between 1882 and 1886, Dr. Schuyler Skaats Wheeler developed a personal fan and electric fan.

An electric motor company in the US Crocker & Curtis bought this product and put it on the market for users.In 1882, Philip Diehl introduced the electric ceiling fan and Diehl is considered the father of today's modern electric fan. At the end of the 19th century, electric fans were used by households. Heat convection fans are run by alcohol, oil, or kerosene that has spread throughout the world in the 20th century.

In the late 1890s and early 1920s, electric fans were introduced to the United States. Their protective fan cage is not safe because the people at that time did not know, the distance between the nets in the fan cage was very large, wide open so many people, especially children, were injured at hand or arm caused by propeller.

In the 1920s, due to the reform and industrial progress in production, the price of fans was reduced so that many houses could afford to buy. By 1930, fan art was born (Swan Fan). In 1950, fans were produced and painted in all kinds of eye-catching colors.When an air conditioner was introduced in 1960, it was the end of the golden era of electric fans . In the 1970s, Queen Victoria's ceiling fan was popular in the world.

Electric fans today have many new technical improvements

In the 20th century, electric fans became more practical. In the 2000s, the choice of buying a home-compatible aesthetic fan became a big concern for everyone. Electric fans play a big part in everyday life in some countries like Japan, Spain and some other countries. Today, there will be no more electric fans in offices, but instead of air conditioners, but they are very popular in every Vietnamese family.
