Definitions

  • the invention relates to a dust vacuum cleaner comprising a first compartment, delimited by a shell of which a front part has a rigid structure, and which contains a turbine powered by a motor, and a second compartment, constituting a vacuum chamber, which communicates with the first compartment by an air passage formed in the front part, a cover pivotally mounted on the front part defining with it the second compartment when said cover is in the closed position such that external faces of the rigid front part cooperate with of the internal faces of the cover.
  • the seal between the vacuum chamber and the outside is generally produced by an attached gasket and disposed on the external faces of the front part of the shell intended to cooperate with the internal faces of the cover, so that this seal is slightly crushed when the cover is closed on the hull; such a seal is an expensive piece because it must be made of a flexible material resistant to crushing and wear.
  • the cover is made of a rigid material, generally identical to the material that makes up the front part of the shell, 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 making up the device.
  • the cover is made of a plastic material of elasticity substantially greater than that of the material forming the rigid front part, and the assembly of the cover on the rigid front part constitutes a press fit.
  • the cover can be substantially deformed under the effect of the vacuum created in the second compartment, so that the external faces of the rigid front part and the internal faces of the cover cooperate in an adhesive connection reinforcing friction, and therefore perfectly waterproof, without the need for the addition of a seal.
  • FIG. 1 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the open position;
  • FIG. 2 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the closed position;
  • FIG. 3 is a partial sectional view of a vacuum cleaner according to the invention, the cover being in the open position;
  • - Figure 4 is a partial sectional view of a vacuum cleaner according to the invention, the cover being in the closed position;
  • FIG. 1 shows a dust vacuum cleaner 1 according to the invention, which comprises a first compartment 2, delimited by a shell 2 'of which a front part 3 has a rigid structure.
  • This shell has a housing 5 for receiving a turbine actuated by a motor power, not shown.
  • the vacuum cleaner has a second compartment 6 constituting the vacuum chamber, which can contain a dust bag - not shown - and 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 rigid front part 3 and by a separation face 4 of this rigid front part, when the cover 8 is in the closed position. In this position, the cover 8 fits onto the rigid front part 3, so that external faces 9 of the rigid front part 3 cooperate with internal faces 10 of the cover.
  • the cover 8 is made of a plastic material of elasticity substantially greater than that of the material forming the rigid front part 3, and the assembly of the cover 8 on the rigid front part 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 them 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 hand, as well as the tight connection between _.es two parts, allow to obtain such a quality of sealing, necessary reliable operation of the device, without resorting to a gasket. This results in a reduction in the number of parts making up the device, and consequently in the manufacturing cost.
  • the assembly is of the conical type and the external faces 9 for this purpose have a nesting slope 9 ′ of shape complementary to that of the internal faces 10 of the cover 8.
  • FIG. 2 the same dust vacuum cleaner is shown, the 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 peripheral shoulder 11 of the front part rigid 3.
  • a projecting member 13 formed on the rigid front part 3 has a housing 18 intended to receive an elastic locking member - not shown and known per se - which, by cooperating with a cavity 14 formed on a wall of the cover 8, secures the closing of the cover, before powering up the device.
  • the rigid front part 3 is for example made of Acrylonit ⁇ le Butadiene Styrene, also designated by the acronym ABS, whose important characteristics in this type of manufacture are rigidity, lightness and impact resistance.
  • the cover 8 and the shell 2 ′ are preferably made of copolymer polypropylene, a material which, in addition to its characteristics of relative elasticity, has a lower cost than that of ABS.
  • a vacuum cleaner of the type proposed by the invention therefore combines equivalent efficiency with respect to the devices of the prior art, with a significantly lower manufacturing cost due to the removal of the seal, also due to the replacement in the composition of the cover, of ABS by a material of lower price.
  • Figures 3 and 4 show the device according to the invention, according to simplified sections in the longitudinal plane of symmetry of the device, in the respectively open and closed positions of the cover.
  • the protruding member 13 ensures the continuity of 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 comprises a shoulder 16 intended, by cooperating with the edge 17 of the part of the cover comprising the cavity 14, to limit the nesting of the latter.
  • a dust vacuum cleaner according to the present invention has a reduced cost and a more constant reliability over time, due to the removal of the seal which constitutes a part liable to deterioration.
