Bladeless fans, also called air multipliers, were invented by James Dyson. This new type of electric fan can give people a cool feeling the same as traditional fans, but its shape is very fashionable and unique. At the same time, the absence of blades reduces safety risks. Besides this, what are the advantages and disadvantages of bladeless fans?
Before answering this question, let's first understand how bladeless fans work. It works a bit in the same way as an airplane engine. It is understood that the design of the bladeless fan is inspired by the bladed hand dryer. The fan blades are installed at the bottom, and the air is sucked in from the bottom of the fan, reinforced several times by the turbine motor, and then pushed to the hollow tubular ring at the bottom.top of the fan with a larger air volume. enhanced airflows will be sprayed along the inner wall of the top of the tubular ring. A cool wind emerges.
This principle seems simple, but it is difficult to implement. Dyson is said to have spent almost four years studying the basis of this fan's motor, optimizing it with the opening required for the machine, and carrying out hundreds of experiments and simulations.
Today, because blade fans have many defects, more and more families choose to buy bladeless fans. First of all, using blade fans is dangerous, especiallyfor children. Blades spinning at high speeds can cause serious injury to children who accidentally touch them. On the other hand, a bladeless fan is very safe because it has no blades and does not present any tesafety risks.
Secondly, blade fans will make a lot of noise when running, especially some fans that have been used for a long time. But bladeless fans are quite quiet at low speeds, producing almost no noise. In addition, the cold air generated by the bladeless fan is 100% natural wind. Unlike traditional fans, the uninterrupted flow of cold air with uniform wind speed cangive consumers a better experience.
But the bladeless fan is not perfect. It also has some flaws, such as difficult cleaning of the air inlet and outlet, unstable chassis, easy tilting, and high power consumption. Finally,air conditioners, blade fans, and bladeless fans all have their pros and cons. So you should compare according to your own needs, combined with performance, price and other aspects, and choose the one that suits you best.
