Benefits of technology
[0020] Another advantage of the present invention is that, with the reduction in the number of components to be assembled in sequence, the vibrations and noisiness of the electric cleaning apparatus are consequently reduced.
is that, with the reduction in the number of components to be assembled in sequence, the vibrations and noisiness of the electric cleaning apparatus are consequently reduced.
Problems solved by technology
One of the main disadvantages of known drive units is that, due to their specific conformation, they cannot be assembled in structures having different shapes from those for which they have been expressly designed and made.
This disadvantage entails the need to design and construct, every time, a specific drive unit, with specific components, according to the shapes and sizes of the electric cleaning apparatus, with a consequent increase in both the design and production costs of said electric cleaning apparatuses.
Moreover, again because of this disadvantage, different types of spare parts necessarily have to be produced, for each individual model of apparatus, thus increasing both the storage costs in the warehouse and also the distribution costs.
Another disadvantage is that such known drive units consist of a high number of components which, apart from having higher overall costs, tend once they have been assembled to generate vibrations which produce great noisiness of the electric cleaning apparatus.

Embodiment Construction
[0026] With reference to FIG. 1, a drive unit 10 according to the present invention is arranged inside an outer structure 11 of an electric cleaning apparatus 12.
[0027] In this case, we shall make specific reference to an electric cleaning apparatus 12, such as a crumb vacuumer, but it is clear that the drive unit 10 can be assembled on any type whatsoever of electric cleaning apparatus, such as a vacuum cleaner, an electric brush or otherwise.
[0028] The outer structure 11 comprises two shells 13 and 15, able to be selectively dis-assembled from each other, so as to allow easy access to the drive unit 10.
[0029] The shell 13 is arranged, during use, at the front and comprises a suction hole 16 connected to the drive unit 10 by means of a suction pipe 17, so that the activation of the drive unit 10 determines the suction of dirt and dust through the suction hole 16. Inside the shell 13, located between the suction pipe 17 and the drive unit 10, a filter is arranged, of a known type...

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
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of International Application No. PCT / IB2004 / 001594, filed May 18, 2004, which was published in the English language on Dec. 2, 2004, under International Publication No. WO 2004 / 103143 A1, and the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention concerns a drive unit for an electric cleaning apparatus, such as a vacuum cleaner, an electric brush, a crumb vacuumer or suchlike. The drive unit according to the present invention comprises an electric motor, a suction fan and a unit to command the motor, and is able to be arranged inside an outer structure of the electric cleaning apparatus, irrespective of the aesthetic form of the latter. [0003] Electric cleaning apparatuses are known, such as for example vacuum cleaners, electric brushes, crumb vacuumers or suchlike, used in household cleaning. [0004] Such known apparatuses normally comprise ...
