Definitions

  • 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.
  • Electric cleaning apparatuses such as for example vacuum cleaners, electric brushes, crumb vacuumers or suchlike, used in household cleaning.
  • Such known apparatuses normally comprise an outer structure provided inside with a drive unit which creates the suction, and outside with a plurality of accessories, such as suction pipes, handles, grips, suction brushes or otherwise, arranged according to the specific function of the electric cleaning apparatus used.
  • the drive units normally assembled in known-type apparatuses generally have an electric motor, a unit to command the latter, and a connection portion with the suction body.
  • 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.
  • One purpose of the present invention is to achieve a drive unit for an electric cleaning apparatus which is of the substantially universal type, that is, which can be assembled on any electric cleaning apparatus, irrespective of the shape thereof.
  • Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art, to achieve this purpose and to obtain other purposes and advantages.
  • a drive unit is able to be assembled inside a structure of an electric cleaning apparatus, and comprises at least an electric motor associated with suction means, that create a suction flow inside the structure, and command means, that selectively command the functioning parameters of the electric motor.
  • the electric motor, the suction means and the command means are assembled together and integrated in a single body, so as to be arranged unitarily inside the aforesaid structure, irrespective of the shape thereof.
  • the drive unit according to the present invention also comprises flange means removably attached on a box-like containing body for the electric motor, which allow to connect the single body, pre-assembled, with the structure of the apparatus.
  • Such flange means comprise adaptor means that allow to center the single body with respect to the structure, according to the shape of the latter.
  • This advantage leads to designing a single drive unit, substantially irrespective of the electric cleaning apparatus, with a consequent reduction in both the design and production costs of the electric cleaning apparatuses.
  • 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.
  • FIG. 1 is an exploded perspective view of an electric cleaning apparatus in which a drive unit according to the present invention is assembled;
  • FIG. 2 is a three-dimensional view of the drive unit in FIG. 1 ;
  • FIG. 3 is an exploded perspective view of the drive unit in FIG. 1 .
  • a drive unit 10 is arranged inside an outer structure 11 of an electric cleaning apparatus 12 .
  • an electric cleaning apparatus 12 such as a crumb vacuumer
  • 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.
  • 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 .
  • 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 .
  • a filter is arranged, of a known type and not shown in the drawings, which allows to filter the air sucked in and to retain the dirt.
  • the shell 13 also comprises an automatic coupling element 19 able to cooperate with a mating attachment seating 20 made on the shell 15 to maintain the two shells 13 and 15 selectively coupled in removable manner.
  • the shell 15 comprises an inner housing seating 21 , inside which the drive unit 10 is arranged, and an outer gripping handle 22 , by means of which the user can comfortably handle the electric cleaning apparatus 12 .
  • the drive unit 10 comprises a connection flange 23 and a box-like containing body 25 , inside which an electric motor 32 is arranged ( FIG. 3 ), of a known type, connected to a suction fan 33 which causes a suction flow inside the electric cleaning apparatus 12 .
  • the drive unit 10 also comprises a command unit 26 for the electric motor 32 .
  • connection flange 23 is substantially circular in shape and comprises, in a central zone, a grid 27 for the passage of air and two attachment fins 29 for the filter that retains the dirt.
  • connection flange 23 also comprises a shaped crown 24 , with a profile mating with that of the housing seating 21 , so as to allow to center the drive unit 10 with respect to the relative housing seating 21 .
  • the shaped crown 24 is made in a piece on the connection flange 23 , even if the shaped crown 24 can be removable with respect to the connection flange 23 and temporarily attached to the latter by means of screws or other suitable means.
  • connection flange 23 is connected in removable manner to the box-like containing body 25 by means of hooks 30 , screws, bayonet type couplings, or otherwise, so as to allow possible inspection of the functional part of the drive unit 10 in a simple and rapid manner.
  • the box-like containing body 25 is also provided with a lead-in element 31 to facilitate the insertion of the drive unit 10 into the relative housing seating 21 .
  • An annular shock-absorber packing 34 is located between the suction fan 33 and the grid 27 of the connection flange 23 , and also guarantees a pneumatic seal.
  • the lead-in element 31 can also be autonomous with respect to the box-like containing body 25 , and can be assembled and dis-assembled independently with respect to the latter.
  • the command unit 26 is attached to the rear part of the box-like containing body 25 .
  • the command unit 26 is also of a substantially known type and comprises a command knob 35 and a connection interface 36 with an electric cable in turn connected to the electric energy distribution network.
  • the command knob 35 is able both to switch on the electric motor 32 , and also to regulate the functioning parameters thereof, such as the power and the number of revolutions.
  • the command knob 35 is able to protrude, during use, from the upper part of the shell 13 through a suitable aperture, not shown in the drawings, made on the latter. In this way the command knob 35 is constantly accessible to the user for all the steps wherein the electric cleaning apparatus 12 is used.
  • the command unit 26 is thus integrated with the box-like containing body 25 of the electric motor 32 , and contributes to making the entire drive unit 10 compact. The latter is therefore not constrained by the shape of the shells 13 and 15 and consequently that of the electric cleaning apparatus 12 on which it is installed.
  • the drive unit 10 can be assembled substantially on any type of electric cleaning apparatus 12 .
