Embodiment Construction

[0080] refer to figure 1 , which shows a first embodiment of a hand-held vacuum cleaner 2 comprising: a main body 4; a handle 6 connected to the main body 4; a cyclonic separation device 8 mounted on the main body and transversely across the main body; and a dirty air channel 10 having a dirty air inlet 12 at one end. The vacuum cleaner includes: an electric motor that engages a fan for generating air flow through the vacuum cleaner; and a rechargeable battery (not shown) Provides electrical energy to the motor when electrically connected to the motor.

[0081] refer to Figure 2 to Figure 8 , which shows a structure including a motor 16, a fan 18 and a cyclonic separation device 8. The electric motor has a drive shaft 20 with a central axis 21 . The fan is a centrifugal fan 18 with an axial inlet 22 facing the motor and a tangential outlet 24 . The diameter of the fan is 68mm. The fan is mounted on the drive shaft that sits on top of the motor. In use, an electric moto...

Abstract

A vacuum cleaner (802) comprising: a motor coupled to a fan for generating air flow; a dirt separation means (8) located in a path of the air flow generated by the fan; a cleaner head (812) located in the path of the air flow upstream of the dirt separation means; at least one support wheel (807) for supporting the vacuum cleaner upon a floor; and an elongate body (804) with a handle (806) at a longitudinal end, wherein the motor, the fan, the cleaner head, the dirt separation means and the at least one support wheel are arranged about an opposite longitudinal end of the elongate body to the handle, wherein the elongate body is telescopically extendible to alter the length of the vacuum cleaner between a compact position and an extended position and wherein the extended position is at least double the length of the compact position.

Description

technical field [0001] The present invention relates to a vacuum cleaner. Background technique [0002] Vacuum cleaners are well known for collecting dust and dirt, but wet and dry variant vacuum cleaners capable of collecting liquids are also known. Typically vacuum cleaners are intended for use in residential environments, but they may also be used in other environments such as construction sites or gardens. Typically, they are powered by electricity and thus include: an electric motor; a fan connected to the output shaft of the motor; an inlet for dirty air; an outlet for clean air; and for dust, dirt (and possibly liquids) collection chamber. Power for the motor may be provided by mains power, in which case the vacuum cleaner will also include a power cord; by a removable and replaceable battery pack; or by one or more built-in rechargeable batteries , in which case the vacuum cleaner also comprises some means for connecting the vacuum cleaner to the charging unit, su...
