Dyson patent shows wash-dry of hands from same fixture

Dec 04, 2012 by Nancy Owano report

(Phys.org)—Dyson, the British design and manufacturing company known for its vacuum cleaners, fans, and hand dryers, has yet another innovative cleaning design on the burner. This time Dyson has come up with the idea of providing a tap that washes and dries your hands from one and the same device. There would be no need to move away from the sink and use a hand towel if at home or to stand in line to wait for a free hand dryer at a public restroom. The idea is that a single faucet on the sink can behave as air blower and water spout for cleansing hands. Dyson, a British company, filed the patent in the U.S. on May 17.

Sensors play a role in this invention, releasing water to clean your hands and recognizing when you place open palms under ducts that they are ready for a blast of air for drying. The patent filing proposes a "dual-purpose fixture for a sink or wash basin, incorporating both a water tap and a hand dryer. The water tap has a spout arranged to project over the basin of the sink, and the hand dryer incorporates two or more hand-dryer nozzles—at least one for each of a user's hands. The left-hand nozzle is located on the left-hand side of the spout and the right-hand nozzle is located on the right-hand side of the spout, specifically so that the spout acts as a dividing partition between the two hand-dryer nozzles. This encourages correct usage of the hand-dryer. The fixture may be fitted to a sink or wall-mounted above the sink."

Patent filings such as this quickly catch buzz because the Dyson name is associated with inventiveness and good engineering; James Dyson, after graduating from London's Royal College of Art, began designing gadgets and machines with an early milestone becoming the bagless vacuum cleaner that eventually became a UK best-seller. Dyson machines are in the permanent collections of the and London's Victoria and Albert Museum, among other places.

As for drying machinery, Dyson engineers have been brainstorming better designs and technologies for hand drying, with their Airblade hand dryer. Energy efficiency and good hygiene are some of the promotion points driving the product. Dyson engineers, according to the company, and scientists spent three years developing, testing and refining the Airblade for drying hands. They quoted a study that said that paper towels and warm air hand dryers generate 70 percent or more carbon emissions than the Dyson Airblade hand dryer. Rather than warm air, the Dyson Airblade uses sheets of cool cleaned air to scrape water from hands. Air is forced through two apertures described as the width of an eyelash, creating sheets of travelling at 400 mph. Water is scraped from hands in twelve seconds.

Blowing air from a public restroom across one's hands has never struck me as particularly hygienic.

"Airblade hand dryer uses sheets of cool cleaned air..."

Not exactly what I'd want in the middle of winter.

However, if it cuts the time spent in those odiferous environs even for a few seconds, it's ingenious.

There have been numerous studies showing that hand air dryers are very un hygienic and notorious for effectively spreading bacteria and virus's. I prefer paper towels and using it to open the door out behind the guy who did not wash his hands after taking a crap.

The AirBlade hand dryer is here some time already and from its construction follows, it's very hygienic - all water droplets are trapped inside it. IMO it belongs into best Dyson's inventions.

If Dyson's track record with vacuum cleaners is any indication; there are two drawbacks to his products. First, they are way more expensive than the competitors; second, as soon as he comes out with a new design he obsoletes the previous designs. I bought a Phantom Fury back a few years. When it broke down I found there was no way to get it fixed. The company does not make replacement parts, and nobody will service it. So, after a couple years, my not-cheap vacuum was a pile of junk. I would have done better buying a cheaper vacuum that could be serviced. I will never buy another Dyson product. For those prices, I can do better buying a professional product with replacement parts and continued service.
