Definitions

  • the present invention relates to the field of vacuum cleaners making it possible to vacuum up dust and waste present on a surface to be cleaned, which may for example be tiles, parquet, laminate, carpet or a rug.
  • a vacuum cleaner and more particularly a portable vacuum cleaner, comprises in a known manner a main body equipped with a suction duct, a waste separation and collection device mounted on the main body, and a suction motor housed in the main body, the suction motor having a motor shaft and being configured to generate an air flow through the suction duct and the waste separation and collection device.
  • the main body further comprises an air exhaust circuit through which the air flow generated by the suction motor is exhausted to the outside of the main body.
  • the air exhaust circuit is equipped with a filter configured to filter the air flow flowing through the air exhaust circuit.
  • the noise generated during the operation of such a portable vacuum cleaner may, however, be significant, which may make the use of such a portable vacuum cleaner unpleasant.
  • the document FR 309 4622 discloses such a portable vacuum cleaner.
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a portable vacuum cleaner which is simple and economical in structure, while significantly reducing the noise generated by the portable vacuum cleaner during its use.
  • the present invention relates to a portable vacuum cleaner comprising a main body equipped with a suction duct, a separation device and waste collection mounted on the main body, and a suction motor housed in the main body, the suction motor having a motor shaft and being configured to generate a flow of air through the suction duct and the waste separation and collection device, the main body further comprising an air evacuation circuit by which the air flow generated by the suction motor is evacuated to the outside of the main body, the circuit the air exhaust being equipped with a filter configured to filter the air flow flowing through the air exhaust circuit.
  • the filter has a generally cylindrical shape and has an internal surface delimiting an internal chamber which is fluidly connected to an air discharge port of the suction motor, and the air exhaust circuit includes a sound absorption wall which extends at least partly into the internal chamber of the filter, the internal surface of the filter and the acoustic absorption wall delimiting a first air vein and a second air vein in each of which is intended to circulate a part of air flow.
  • filter having a generally cylindrical shape
  • the filter could possibly have a substantially frustoconical shape or a generally cylindrical shape with a C-shaped section or a section having the shape of a horseshoe.
  • the internal chamber also adopts a generally cylindrical shape.
  • the specific configuration of the filter according to the present invention makes it possible to reduce the noise generated by the portable vacuum cleaner while generating low pressure losses. Indeed, the fact of separating the internal chamber of the filter into two makes it possible to significantly reduce the amplitudes of the acoustic waves passing through the internal chamber of the filter. The amplitudes of the acoustic waves are generally halved. This reduction in acoustic amplitudes significantly reduces the acoustic emissions of the air flow passing through the filter. Thus, such a configuration of the portable vacuum cleaner makes the use of the latter much more pleasant without significantly reducing the suction performance of the portable vacuum cleaner.

  • the pressure losses induced by the air flows circulating in the two air streams, the amplitudes and frequencies of the acoustic waves passing through the air streams are then substantially identical, which makes it possible to further optimize the sound absorption in the configuration according to the invention where the sound absorption wall is arranged in the internal chamber of a generally cylindrical filter.
  • an off-centered sound absorption wall inside the internal chamber or several sound absorption walls arranged parallel in the internal chamber do not make it possible to obtain optimal results because the passage sections would be different either in terms of section surfaces or section shapes.
