Embodiment Construction

[0049] Like reference numerals denote like parts throughout the specification.

[0050] figure 1 A surface treatment device is shown, which in this example is a vacuum cleaner 1 . The vacuum cleaner 1 comprises a main body 2 and a rolling support structure 4 mounted on the main body 2 for maneuvering the vacuum cleaner across a surface to be cleaned. The cleaning head 6 is pivotally mounted on the lower end of the rolling support structure 4, and the dirty air inlet 8 is arranged on the lower side of the cleaning head 6 facing the surface to be cleaned. A separation device 10 is removably provided on the body 2 and a conduit 12 provides communication between the dirty air inlet 8 and the separation device 10 . A wand and handle assembly 14 is mounted on the main body 2, behind the separation device 10.

[0051] During use, a motor and fan unit (not shown) located within the rolling support structure 4 draws dust laden air into the vacuum cleaner 1 through the dirty air inl...

Abstract

A surface treating appliance includes a plurality of frusto-conical cyclones arranged in parallel. Each cyclone has a relatively wide, rigid frusto-conical portion and a relatively narrow, flexible frusto-conical portion connected to the relatively wide portion. The relatively wide portion includes at least one dirty air inlet, and the relatively narrow portion includes a dirt outlet. The relatively narrow portion vibrates during use of the appliance is dislodged dirt from the inner surface of the relatively narrow portion, the dislodged dirt being expelled from the dirt outlet.

Description

technical field [0001] The present invention relates to a surface treating appliance, in particular a vacuum cleaner comprising at least one cyclone. Background technique [0002] Surface treatment appliances such as vacuum cleaners can separate dirt and dust from the air stream without the use of filter bags. These so-called bagless vacuums are very popular. Most bagless vacuums use a cyclone or centrifugal separator to spin out dirt and dust from the air stream. By avoiding the use of filter bags as the primary form of separator, it has been found possible to maintain a consistently high level of suction, even when the collection chamber is full of dirt. [0003] The principle of cyclonic separation for domestic vacuum cleaners is described in several publications, including EP 0 042 723 . Generally, the air flow entrained with dirt and dust enters the first cyclone separator through a tangential inlet which causes the air flow to follow a spiral or helical path within ...
