Dyson provides vacuum cleaners. It offers upright, canister, and handheld vacuum cleaners. The company also provides accessories, such as asthma and allergy kits, carpet cleaning kits, pet clean-up kits, soft dusting brushes, stiff bristle brushes, multi-angle brushes, home cleaning kits, mattress tools, and spot cleaners, as well as bladeless table, tower and pedestal fans. In addition, it offers spare parts, animal vacuums, cleaners, car cleaning kits, and hand dryers. Dyson sells its products through retailers, as well as online. Dyson employs more than 8,500 people worldwide.
Dyson has developed various technologies in their products, such as the dual cyclone used in vacuum cleaners and their Airblade hand dryers.
Airblade hand dryer:
The Dyson Airblade is a hand dryer for commercial customers, typically made available in public hand-washing facilities. The Airblade uses Dyson’s Digital Motor to produce a stream of air that flows at up to 430 mph (700 km/h) and is claimed to dry the hands in 10 to 12 seconds. The Airblade uses a HEPA filter to remove bacteria and mould from the air. The Dyson Airblade is the world’s first hygienic commercial hand dryer according to NSF International; it is accredited by the British Skin Foundation and the Royal Institute of Public Health as well. The Dyson Airblade is HACCP approved. The first Dyson Airblade was launched in 2006.
Air Multiplier Fans:
The Dyson Air Multiplier was announced on 18 October 2009 as an electric fan, intended to provide smoother airflow and, having no exposed rotating blades, operating in a safer manner than conventional bladed fans. Like other bladeless fans, the apparatus itself has no visible external blades, as the fan blades are concealed within the body of the product. The fan works by drawing 27 litres of air per second in through an inlet in the base pillar and forcing it through an outlet in the upper ring. The jet of air travels over the airfoil shape of the ring, creating local low pressure, thereby pulling air from behind it as it decelerates in a process known as inducement, a property of Bernoulli’s principle. Once the air exits the ring it entrains the air in front and alongside, producing an airflow of 405 l/second. Using this process, a small brushless impeller in the fan’s base can power a much larger air outlet without exposing any blades.
Dyson stated that the initially generated air flow is multiplied between 15 and 18 times for the models AM01, AM02 and AM03, projecting a smooth stream of uninterrupted air. In March 2014, the second-generation models of the Air Multiplier were acoustically re-engineered so that the bladeless fans were quieter than their predecessors by improved airflow and a Helmholtz resonator to cancel a 10 kHz whine.
Since the original release, Dyson has produced combination electrical heater and cooling fans based on its Air Multiplier design. In addition, some newer designs have the ability to shift between a wider and shallower or a narrower but farther-reaching stream of air, under user control. Most of the Dyson fans and heaters are controlled by small infrared remote controls, which can be adhered magnetically to the appliance when not in use. A more limited set of control switches is available on the body of the appliance.
The design for a bladeless fan was patented by Toshiba in 1981, but was never manufactured as Dyson thought is was not suitable for the market he wanted to pave. The initial patent claim by Dyson was rejected by the Intellectual Property Office, ruling that it “cannot be considered novel or cannot be considered to involve an inventive step” compared to the Japanese version.
The Air Multiplier fan received the Good Design Award in 2010.
In September 2011, Dyson announced the Dyson Hot fan heater (AM04), using Air Multiplier technology. Like most fan heaters it has a thermostat to control the temperature, and can also be used as a fan. All AM04 models made prior to 1 April 2014 were subject to a no-charge product recall for repairs because of a fire risk.
In March 2015, Dyson released their new Air Multiplier Humidifier. It uses Ultraviolet Cleanse technology to clean water by running it through ultraviolet light twice before it is released. A piezoelectric transducer in the base vibrates up to 1.7 million times a second to break the water down into small particles which are drawn up and added to the air with air multiplier technology.
In January 2016, Dyson released the Dyson Pure Cool air purifier. It uses the same air multiplier technology to blow air as well as a .99 micron HEPA filter to trap air particles. Along with the filter to trap slow particles the unit uses low-force velocity to trap fine particles within the filter as well.
Contrarotator washing machine:
The discontinued Dyson CR01 Contrarotator is a washing machine with two counter-rotating drums, the first of its type. Each drum had 5,000 spin perforations to help evacuate water. The machine was first available in November 2000. Dyson’s next washing machine, in 2004, was the CR02, with “Flowcheck” and “Allergy” models. The company later stopped making washing machines the same year, as they were unprofitable for the company. As of November 2012, Dyson no longer supports or services the Contrarotator washing machines, which it has officially declared obsolete.
On 27 April 2016, Dyson introduced the Supersonic handheld hair dryer. The digital motor V9 is housed in the handle.
In 2015 Dyson introduced the “Csys” range of LED lamps. The lamps incorporate heat pipe technology designed to extend the life of the product.
Root Cyclone technology:
The Dyson Root Cyclone technology is used in all Dyson vacuum cleaners from DC07. The DC17, DC22, and DC23 use the improved Root Cyclone & Core Separator, also called Radix Cyclone, Intermediary Cyclone, or Level 3 Root Cyclone Technology.
