Abstract

A bladeless fan (sometimes called an air multiplier) blows air from a ring with no external blades. Its blades are hidden in its base. The first concept was created by Toshiba in 1981.Dyson claims that its bladeless fans (U.S. Patent 8,454,322) produce a more constant airflow than traditional fans.The air is drawn in by a fan in the base and then directed up into a ring. It comes out of a crack all around the ring and passes over a shape like that of an aircraft wing. Industrial designer Sir James Dyson named his fan the Air Multiplier.Dyson sued Chinese companies because they began selling bladeless fans for much less than Dyson.The Chinese responded that Dyson cannot patent an invention that has already been invented, that Toshiba invented the fan in 1981 and its patent expired after 20 years.

A fan without a scalpel (sometimes called an air multiplier) expels air from a ring without external blades. Its blades are hidden in its base. The first concept was created by Toshiba in 1981. Dyson states that its paddleless fans (US Patent 8,454,322) produce a more constant airflow than traditional fans. The air is attracted by a compressor at the base and then directed towards a ring. It comes out of a slit around the ring and passes over a shape like the wing of an airplane. Industrial designer Sir James Dyson named his fan the Air Multiplier. Dyson sued Chinese companies because they started selling non-scalpel fans for much less than Dyson.

There are no moving leaves visible in this fan. The blade is hidden inside the fan pedestal. In 2009, James Dyson first introduced a new innovation in the no-scalpel fan by adding air multiplication technology. This Dyson air multiplier fan generates an air flow of up to 55 mph. The fan contains a brushless electric motor and this motor rotates nine aligned asymmetric blades that join with a rotor. Usually, the upper frame of this fan has a ring shape. The frame is not flat; it is made in such a way that the edge can create a curve of an angle slope of 16 degrees. Air flows through the channel in the fan pedestal when the engine is started. After that, the air flows through the hollow tube. Then, air is fired through 16 mm slits. This air flows smoothly, rather than turbulently as with a blade fan. The curvature of the inner wall of the fan creates a negative pressure area, like the wing of an airplane, to attract more air to the flow and, therefore, "multiply" it. This property of the air is called incentive. In addition, the air that surrounds the edges of the fan also begins to flow with the direction of the breeze or is "dragged" towards it. Dyson says that air multiplication technology increases the output of air flowing through the tube at least 15 times compared to the air flow emitted by a traditional fan.
