Definitions

  • the invention relates to a vacuum cleaner dust including a first compartment, delimited by a shell of which a front part presents a rigid structure, and which contains a powered turbine by a motor, and a second compartment, constituting a vacuum chamber, which communicates with the first compartment by an air passage formed in the part front, a cover pivotally mounted on the part anterior delimiting with it the second compartment when said cover is in the closed position such that external faces of the rigid front part cooperate with internal faces of the cover.
  • the seal between the vacuum chamber and the exterior is generally carried out by an attached and arranged seal on the external faces of the anterior part of the shell intended to cooperate with the internal faces of the cover, so that this seal is slightly crushed when closing the cover on the hull; such a joint is an expensive piece because it must be made in one soft material resistant to crushing and wear.
  • the cover is manufactured in a rigid material, generally identical to the material which composes the front part of the hull, or even the shell as a whole.
  • the main object of the invention is to remedy this drawback, namely to seal the vacuum chamber by reducing the number of parts component of the device.
  • the cover is made in a plastic material with elasticity substantially greater than that of the material forming the rigid front part, and the assembly of the hood on the rigid front part constitutes a press fit.
  • the cover can significantly deform under the effect of depression created in the second compartment, so that the external faces of the rigid front part and the internal faces of the cover cooperate in a connection adherent reinforcing friction, and therefore perfectly waterproof, without the need for the addition of a seal.
  • FIG. 1 shows a dust extractor 1 according to the invention, which comprises a first compartment 2, delimited by a 2 'shell, part of which front 3 has a rigid structure.
  • This shell has a housing 5 intended to receive a turbine powered by an electric motor, not shown.
  • the vacuum cleaner has a second compartment 6 constituting the vacuum chamber, which can contain a dust bag - not shown - which communicates with the outside by a mouth (E) and with the first compartment 2 by an air passage 7 formed in the rigid front part 3.
  • This second compartment 6 is delimited by a cover 8 pivotally mounted on the part rigid anterior 3 and by a separation face 4 of this rigid front part, when the cover 8 is in closed position. In this position, the cover 8 fits on the rigid front part 3, so that faces external 9 of the rigid front part 3 cooperate with internal faces 10 of the cover.
  • the cover 8 is produced in a plastic material with elasticity substantially greater than that of the material forming the rigid front part 3, and the assembly of the cover 8 on the front part rigid 3 constitutes a press fit.
  • the cover 8 undergoes a slight deformation under the effect of which its internal faces 10 in contact with the external walls 9 of the rigid front part 3, are pressed against the latter forming with they an adherent and perfectly waterproof connection.
  • the relative rigidity of the materials constituting the cover 8 on the one hand, and the rigid front part 3 on the other part, as well as the tight connection between the two parts, allow to obtain such a seal quality, necessary for reliable operation of the device, without however, use a seal. It follows a reduction in the number of parts making up the device, and therefore the manufacturing cost.
  • the assembly is of the conical type and the external faces 9 for this purpose have a slope 9 ' interlocking shape complementary to that of the faces internal 10 of cover 8.
  • FIG 2 the same vacuum cleaner is shown dust, cover 8 being in its closed position on the rigid front part 3, position in which the edge 12 of the cover 8 is in abutment on a shoulder peripheral 11 of the rigid front part 3.
  • a protruding member 13 formed on the rigid front part 3 has a housing 18 intended to receive an organ locking elastic - not shown and known in soi -, which, by cooperating with a cavity 14 formed on a wall of the cover 8, makes it possible to secure the closing of the cover, before switching on the device.
  • the front part rigid 3 is for example made of Acrylonitrile Butadiene Styrene, also designated by the acronym ABS, which important features in this type of manufacturing are rigidity, lightness and impact resistance.
  • the cover 8 and the shell 2 ' are preferably made of polypropylene copolymer, a material which more of its relative elasticity characteristics, has a lower cost than ABS.
  • a vacuum cleaner of the type proposed by the invention therefore combines equivalent efficiency compared to prior art devices at a cost of significantly lower manufacturing due to the elimination of the seal, also due to the replacement in the composition of the cover, of ABS by one more material low price.
  • Figures 3 and 4 show the device according to the invention, according to simplified sections in the plan longitudinal symmetry of the device, within hood open and closed positions respectively.
  • the protruding member 13 ensures continuity sealing by cooperation of its external face 15 with the internal face of the cover, in its part comprising the cavity 14; said projecting member 13 also includes a shoulder 16 intended, cooperating with the edge 17 of the part of the cover comprising the cavity 14, to be limited the nesting of the latter.
  • a vacuum cleaner according to the present invention presents a reduced cost and more reliability constant over time, due to the removal of the joint which constitutes a part liable to deterioration.
