Problems solved by technology
[0006] One of the main disadvantages of the known drive units is that, due to their specific shape, they cannot be installed in structures whose shape differs from that of the structures designed and made for them
[0007] This disadvantage makes it necessary to design and produce a special drive unit with a specific shape each time according to the shape and size of the electric cleaning device, thus increasing the design and production costs of the electric cleaning device
[0008] In addition, due to this disadvantage, for each electric cleaning device, different types of individual components must be produced, which increases storage costs and distribution costs.
[0009] Another disadvantage is that known drive units of this type have a high number of parts, which, in addition to increasing the overall cost, are prone to vibrations once assembled, making the electric cleaning device noisy

Embodiment Construction
[0024] Referring to FIG. 1 , a driving unit 10 of the present invention is disposed in an external structure 11 of an electric cleaning device 12 .
[0025] In this case we will specifically describe an electric cleaning device 12 such as a vacuum cleaner, but obviously the drive unit 10 may be mounted on any type of electric cleaning device such as a vacuum cleaner, electric brush or the like.
[0026] The outer structure 11 comprises two housings 13 and 15 which are selectively detachable from each other to allow easy access to the drive unit 10 .
[0027] In use, the housing 13 is disposed on the front side and includes a suction hole 16 connected to the driving unit 10 through a suction pipe 17 so that actuation of the driving unit 10 makes it possible to suck dirt and dust through the suction hole 16 . Between the suction pipe 17 and the drive unit 10 in the housing 13 is arranged a filter of a known type not shown in the figures, which filters the sucked-in air and retai...

Drive unit ( 10 ) assembled inside a structure ( 11 ) of an electric cleaning apparatus ( 12 ), which comprises an electric motor associated with suction members ( 33 ), that create a suction flow inside the structure ( 11 ), and command members ( 26 ), that selectively command the functioning parameters of the electric motor. The electric motor, the suction members ( 33 ) and the command members ( 26 ) are assembled and integrated together to form a single body, so as to be able to be arranged unitarily inside the structure ( 11 ).
Description
technical field [0001] The invention relates to a drive unit for electric cleaning devices such as vacuum cleaners, brushes, crumb vacuumers and the like. The driving unit of the present invention includes a motor, a suction blower, and a control unit of the motor, and can be installed in the external structure of the electric cleaning device regardless of the appearance of the electric cleaning device. Background technique [0002] Electric cleaning devices such as vacuum cleaners, electric brushes, vacuum cleaners etc. are known for household cleaning. [0003] Known devices of this type generally consist of an external structure in which a drive unit for actuating the suction is arranged, externally provided with a plurality of accessories such as suction pipes, handles, grippers, suction brushes, etc. arranged according to the specific function of the electric cleaning device used . [0004] The drive unit usually installed in the known cleaning device generally compri...
