Dyson could be about to launch a bladeless desk fan to keep you cool based on technology it has previously used in its hand driers and vacuum cleaners.

The details of a new patent and trademark have been filed for a "Dyson Air Multiplier" that suggests a new range of personal cooling products are on their way.

According to a forum post on a vacuum cleaner site (exciting, we know) the patent describes:

"A bladeless fan assembly (100) comprising a nozzle (1) mounted on a base (16) housing means for creating an air flow through the nozzle (1)".

"The fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan - i.e. air flow is created by a bladeless fan".

"These arrangements create a fan assembly with a compact structure."

Why would you want a bladeless fan? It's all about noise and cost according to the forum post.

"We file hundreds of patents every year to protect our ideas. Some make it, some don't", a Dyson spokesperson told us.

  • Anyone with a modicum of knowledge about fans knows that to make a fan quieter you use larger blades so they can move more slowly. You could try channelling through some conduit as Dyson does but then there will obviously be unpleasant draught noise. In contrast to his cyclone vacs, this appear to be second-rate tech. Profit multiplier more like. I can only suppose that Mr Dyson is struggling to make ends meet with his limited supply of billions. Posted by robin Clarke, uk
