Sir James Dyson may be building a silent hairdryer. He is the brains behind the bladeless fan and bagless vacuum cleaner.
Diagrams seen at the UK's patents office show that Dyson's company has filed patents for a hand-held blower that features an insulating chamber, the Guardian reported.
AdvertisementThe usual hairdryers are extremely loud, and reach up to 75 decibels, which is as noisy as a vacuum cleaner, but is held besides your head.
The patents are surprisingly detailed. The design works by combining air that is pulled in through the motor element and from the sides of the machine that would mean the motor may be smaller and lighter - and, perhaps makes less noise.
