Well, to be fair Dyson haven't announced this product, as per their usual policy of not mentioning new products in development until they're ready to hit the market.
The proposed dishwasher doesn't require hydrogen peroxide, it makes it internally from the pre-salted tap water.
As with Airblade, in patents the devil is in the detail. Other manufacturers already have hand driers of a similar form factor. Dyson hope to improve on the efficiency based on 1) Dyson Digital Motor 2) Outlet design 3) No need for drainage (some others have a drawer which needs to periodically empted of waste water or plumbed in).
Look at the dishwasher patent - it goes in to detail about the properties of hydrogen peroxide, it's short effective chemical life and how a system could be developed to ensure a supply is available each time a wash is required.
Initially, I did wonder if a dishwasher using hydrogen perioxide could be as effective as the detergents on the market. It's no good bring an expensive new product to market if it's not as good as the competition, even if it doesn't use water. However, the patent write up goes on to mention that the use of hydrogen perioxide is *particularly* good at cleaning glassware.
To mention that Dyson have other dishwasher patents, including one that details using a highly efficient motor (DDM?) to create a pressure vacuum to aid the dry cycle, so that metalware is cool to touch straight after the cycle is complete.
Venson, thanks for the links. Presumably the Sharp method is an improvement on the Dyson method as is it is ready to go at a moment's notice?
The ultrasonic dishwasher that requires no water sounds very interesting. But I wonder how well it does glassware?
As to if Dyson ever launch a dishwasher, it's impossible to say. They might have played around with the technology, evaluated the competition and decided to leave it for the time being.
But like all R&D projects, spin off uses can come to the fore. The Dishwasher patent mentions that a hydrogen perioxide producing unit could be used as part of a handwash dispenser. This would give Dyson another string to their bow in washroom equipment supply. The airblade being environmentally friendly in replacing paper towel / hot air driers and a washroom hand sanitizer that doesn't need to be replenished and the residue that breaks down in to a harmless substance.
