Dyson's New Tap Does Both Wet And Dry
Dyson has unveiled three new products - including a tap that washes a person's hands and then dries them.
The company claims the Airblade Tap, along with two new versions of its existing Airblade dryers, are the fastest and most hygienic way for a person to dry their hands.
The tap uses infrared sensors to pinpoint the hand positions and release water from the tap stem.
Two branches off the tap stem have air outlets which blow high-velocity sheets of unheated air over the hands to dry them.
Tech website Wired, which tested the device, said the main benefit was that the washing and drying operations both took place over the washbasin, meaning water would not be blown onto the bathroom floor.
While Dyson said hands could be dried in 12 seconds, Wired's testers reported a drying time of 13 to 14 seconds.
The Airblade Tap may not appeal to everyone, though, as it has a price tag of £999.99.
The other devices released by the firm are the Airblade V hand dryer, which is 60% smaller than the existing dryer, and a re-engineered Airblade made from polycarbonate, weighing 1.1kg less than the original.
Conventional hand dryers use one column of air to evaporate the water from a person's hands, accompanied by hand rubbing.
In contrast, Dyson says its Airblade devices force air through tiny apertures at 430mph, quickly scraping water from a person's hands like a windscreen wiper, leaving them fully dry.
The company singles out two technologies that are key to the process.
The new dryers use the V4 brushless motor, which is made of a bonded magnet encased in a carbon fibre sleeve.
It says the V4 is one of the world's smallest and fully integrated 1600W motors. Using digital pulse technology, it accelerates from 0-90,000rpm in less than 0.7 seconds.
The company said it cost £26.9m to develop, but in its lifetime each motor would shift around 162,000 cubic metres of air - enough to fill 26 million balloons.
The Dyson hand dryers also use high-efficiency particulate (HEPA) air filters to remove 99.9% of bacteria from the air in a bathroom before it is blown onto the user's hands.
