Definitions

  • the invention relates to the field of household appliances vacuum cleaners and more particularly the structure of a vacuum cleaner.
  • the present invention aims to provide a device for reducing the noise related to the operation of the vacuum cleaner.
  • Many documents address this issue, including proposing engine containment solutions, associated or not with an extension of the air path from the engine to the outlet openings in the frame of the vacuum cleaner.
  • the documents EP1665972A1 , DE3402603A1 and WO97 / 41631 give examples for noise reduction.
  • the document EP 0345699 has an extension of the air path after the engine with baffles. Such a device is however bulky and therefore bulky.
  • the present invention thus proposes a device for reducing noise in a vacuum cleaner according to claim 1.
  • Said vacuum cleaner comprising a frame, inside which is housed an electric motor associated with a fan for creating, in operation, a suction of air from a pipe, upstream of the engine, terminated by a nozzle, to an air outlet of the frame located downstream of the engine, a filtration device being arranged on the air flow path, preferably upstream of the engine, this last being arranged in a specific fairing.
  • this fairing is pierced with a plurality of air exhaust openings, representing in total an area of at least 10 cm 2 , each opening of the fairing having an area of between 0.75 mm 2 and 40 mm 2 .
  • the fairing allows, by the screen thus formed, to limit the noise.
  • the realization of a multitude of openings makes it possible to distribute the flow of air at the motor output, avoiding that it concentrates in certain privileged zones, a frequent situation when the opening is unique, and which leads to locally high speeds and a passage noise consequent.
  • This new flow distribution is conducive to reducing the air velocities higher by uniformizing the air velocities over the entire perforated surface, thereby reducing noise.
  • the openings total a surface area of at least 10 cm 2 .
  • the apertures of the fairing each have an area of between 0.75 mm 2 and 40 mm 2 .
  • the openings of the fairing are provided in one or more walls of the fairing located opposite the air outlet of the vacuum cleaner frame, thus making it possible not to transmit the noise directly to the outlet without a specific duct or additional room.
  • an absorbent material facing the openings of the fairing, outside said fairing. This material, according to its nature and its dimensions, will absorb some of the acoustic energy coming from these openings at certain frequencies and at a certain level of efficiency.
  • the air speeds at the exit of the fairing are not the same depending on the position of the opening, this fluctuation depending on the configuration of the engine air outlet relative to the openings of the fairing, as well as the air outlet position of the vacuum cleaner frame.
  • the air passage section downstream of an opening of the fairing, and defined by the wall of the fairing and the absorbent material, is all the more important. that the air outlet of the vacuum cleaner frame is close to said opening.
  • the air passage section downstream of the outlet openings of the shroud possibly comprising an absorbent material, has an increasing air flow section in the direction of the flow downstream of the outlet openings. fairing. In this way the passage section of the air thus formed provides a more uniform air velocity.
  • This increase in section is advantageously proportional to the increase in section generated by the fairing outlet openings encountered on the air path, in order to maintain a uniform air velocity between the air velocity at the openings of the air ducts. fairing outlet and the air velocity in this section of airflow just downstream of these openings.
  • the section of passage of the air near an opening is all the more important that the opening is close to the air outlet of the vacuum cleaner frame, in order to reduce the speed of the air in this section of passage of air relative to the air velocity at the outlet openings of the fairing.
  • the absorbent material used is a foam, the pore density of which is preferably greater than 75 pores per inch.
  • an additional sound insulation shroud in which are arranged the part of the fairing comprising the openings, as well as the absorbent material.
  • At least one of the fairings is made of polypropylene
  • the frame can be made, for the most part, expanded polypropylene (EPP).
  • EPP expanded polypropylene
  • the advantages of the realization of the body of the apparatus in this matter are numerous: lightness, respect for the environment, robustness.
  • the body of the vacuum cleaner, or part of the body of the vacuum cleaner, of EPP the expanded nature of the material can be used to pierce said body with a tip. If such an operation takes place, for example during a shock with a metal rod, such as a knitting needle, it is necessary to prevent the latter from coming into contact with the electrically active parts that constitute the electrical connections of the motor.
  • the engine fairing in addition to the acoustic properties described above, protects the active parts of the engine by surrounding them with a specific protection made of a rigid material.
  • rigid material is meant a material resistant to mechanical stresses, this resistance may however cause some deformation of the material, in particular a material passing the standard 60-335-1 Art 30 in relation to the standard IEC 60-695-10-2 which provides for a penetration resistance test of a 2.5mm diameter ball under 20 Newton force to leave an impression smaller than 2mm.
  • the hardness of this material is greater than or equal to 5 Hv.
  • Polypropylene (PP) will be advantageously used for the realization of the fairing.
  • PP and PEP also reduces the diversity of plastics used and facilitates the recycling of the device at the end of its life.
  • the constituent material of the vacuum cleaner ie at least the upper body 4, and preferably also the lower body 2 and the rear part 50, is expanded polypropylene (EPP). ).
  • the rear piece 50 has an unexpanded PP core allowing the piece 50 to be mechanically resistant to a possible violent impact on said handle.
  • the low mechanical strength of the EPP required considerably increase the thickness of the walls to have sufficient strength. Surprisingly, however, even if the volume of material required then causes a larger vacuum cleaner than normal, the mass of plastic material can be greatly reduced, and the weight of the final vacuum can be halved.
  • the high flexibility of the EPP allows for improved shock absorption compared to other plastics traditionally used to make vacuum cleaners.
  • This great flexibility is associated, depending on the degree of expansion, an elastic memory of the material, which also has significant advantages in terms of assembly of the different complementary parts fitted to the body of the device. Indeed, it is thus possible to articulate for example the different lids without hinge and lock simply by deforming the material. This curious particularity also makes it possible to fix inserts, by interlocking, without difficulty.
  • a cover 80 is made of expanded polypropylene and is disposed on the upper body.
  • the mechanical strength of the cover on the upper body 4 of the vacuum cleaner is obtained by interlocking, by deforming the material, as previously explained.
  • This lid allows the closure of the dust bag housing and directs air from the bag to the engine block.
  • this cover can receive, in its thickness, various suction accessories such as small brush, suction lolly, etc.
  • the holding of the upper body on the lower body is provided by rods 12, 13 bearing under the lower body 2.
  • the rods 12 engage with the rear piece 50, while the rod 13 is linked to a rigid piece 90 disposed on the upper body 4.
  • the supports of the rods 12 and 13 under the lower body 2 are preferably associated with the wheels, not shown, of the vacuum cleaner.
  • the latter is associated with a platform 11 for refocusing the wheel relative to the entire vacuum cleaner.
  • the actual assembly of the upper body on the lower body consists, according to the example shown, to screw the rods 12 and 13 in corresponding tubes from the parts 90 and 50, the tubes and / or rods passing through a portion of of the upper body 4.
  • the figure 2 shows in particular such a tube 14 from the part 90, this tube receiving the rod 13 which passes through the lower body 2 through the orifice 24.
  • the screwing thus makes it possible to compress, by means of the parts 90 and 50, the upper body on the lower body, the relatively large deformation of the PPE, as previously described, making it possible to seal between the lower and upper bodies, without a specific seal.
  • the rigid part 90 may have very different shapes and conformations, ranging from a piece covering substantially the entire width of the upper body, as shown, behind the dust bag compartment, to a more indented part. It is even possible to consider the realization of several independent parts.
  • the support surface under the lower body can be provided by a plate more or less extended, like the rigid part 11. It is then possible to have a rigid part under the lower body and more punctual support points on the upper body.
  • the rigid part 90 disposed on the upper body offers the advantage of being able to perform other functions.
  • the rigid part 90 presents the locations of the on / off control button 60, in relation to a switch, as well as that of the rewind button 68 of the electric cable on the reel 10.
  • the rigid piece 90 also has a housing 92 for a housing 94 containing a pleated filter HEPA type, for filtering the air from the dust bag, before entering the engine.
  • the lights, control and operating members 60, 68, as well as the rigid piece 90, the tubes 12, 13 and the rollers, will preferably be made of unexpanded polypropylene.
  • the electrical circuit supplying the motor from an electrical outlet Domestic begins with the power cord of the vacuum cleaner, mounted on the winder 10. Electrical son out of the fixed part of the winder to connect to two terminals 72 of an electronic card 70. Two other terminals 72 of the electronic card 70 are used for connection with the on / off button. Finally two other terminals 72 allow the connection of the motor in the electrical circuit.
  • the vacuum cleaner 1 comprises protections of the active parts of the apparatus, that is to say electrical connections of the various elements of the motor supply circuit.
  • the winder 10 comprises a casing 100 covering the rear part of the winder. This housing thus covers the connection of the electrical wires at the level of the reel.
  • the motor is, according to the invention, contained in a housing 120 whose cover 122 has a chimney 124.
  • the casing 120 is advantageously made of rigid parts made of unexpanded polypropylene.

Such a foam makes it possible to absorb the noise of impact of the air against the vertical wall of the upper body, before reaching the exit 26 of the lower body 2.
  • the round shape of the fairing and the associated foam makes it possible to limit the noise of impact of the air and fluidifies the flow of the air at the exit of the fairing.
  • This outlet is advantageously made opposite the openings 132 in order to extend the air circuit, which is favorable to the reduction of noise.
  • An improvement of this acoustic reduction also consists in arranging a foam 136 in a support 138, in front of the air outlet 26, as presented to FIG. figure 4 .
