The bladeless fan was originally invented by the British man James. Invented by James Dyson, it was originally called the "Air Multiplier". This new invention reduces energy consumption by one third compared to common electric fans. Moreover, it disposes of the blade components of traditional electric fans and innovates the fan's design, making the fan safer, more energy-efficient and more environmentally friendly. However, the first-generation bladeless fan had a relatively low wind force under the premise of energy conservation. Therefore, the products it was put on the market had to increase power consumption in order to enhance the wind force.
Dyson said their fluid power engineers spent four years simulating hundreds of times before they were able to accurately measure the required aperture of the machine and the propeller-shaped engine base, and optimize both, while the fluctuations of the air were mapped by a device called Laser Doppler Annometry.
The bladeless fan, also known as the air multiplier, can generate a natural and continuous cool breeze. As it has no blades, it won't cover with dust or hurt children's inserted fingers. Even more amazing is its unique shape, with a streamlined and refreshing appearance. Inspired by air blade hand dryers. The principle of a hand dryer is to force air through a small opening to "brush" dry the water on your hands. An air multiplier, on the other hand, blows air out through a 1.3-millimeter-wide cut that rotates around a circular ring. As the air is forcibly blown out of this circle, the volume of air passing through can be increased by 15 times, and the maximum speed can be raised to 35 kilometers per hour. The bladeless fan was first introduced in the UK on October 12, 2009. The second generation was launched in Hong Kong in February 2011. Bladeless fans can be classified into countertop bladeless fans and suspended bladeless fans (bladeless ceiling fan lamps).
