Dyson Bladeless Fan – The New it Gadget
Dyson well known for its innovation and popular vacuum line has come up with a new fan concept. The fan is not only more efficient, it is also stylish. The fan is quickly becoming next summers it gadget. The fan is also safer than conventional fans. You can stick your head right in the middle and not receive a nick. Now available for $300 for the 10-inch model and $330 for the 12-inch.
The benefits of this tech are that there are no nasty blades to get fingers caught up in, but also that there’s no “buffeting” — that on-off gush of air caused by fan blades unceremoniously chopping up the air into inelegant segments.
“We realised that this inducement, or amplification, effect could be further enhanced by passing airflow over a ramp,” says Dyson. “And of course this was the point where the idea of a bladeless fan became a real possibility. Here was a way to create turbulent-free air and finally do away with blades.”
How it works: inducement and entrainment
Air is drawn into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil- shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air.
The design is a little funny looking but innovative at the same time. I don’t see homes using these fans in 10 years but who knows, tech is changing constantly.
