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 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 document US 4,015,683 thus describes a device consisting of a connecting tube connected to the vacuum air outlet. At its opposite end is disposed a tube of the same diameter lined with foam by providing a central duct star section, grooves to accentuate the effect of attenuation sounds. At the end of this tube is positioned a plastic plate incorporating the star section of the central duct.
  • This arrangement represents a prominence on the device that can cause a certain fragility of the device during movement of the device.
  • the sound attenuation effect is only related to the path in the foam-filled conduit and the specific star structure of said foam. The inevitable temporal degradation of the foam therefore does not guarantee the durability of the effect.
  • the document US 4,418,443 discloses a vacuum cleaner having a filter bag disposed after the engine, a conduit from the engine entering the bag through a noise attenuation device consisting of a sequence of tubes of different diameters.
  • This noise attenuation device is entirely inside the vacuum bag, and therefore the vacuum cleaner, which makes the device bulky, while making it difficult to access the dust contained in the bag.
  • the present invention proposes to remedy the drawbacks cited by proposing a vacuum cleaner comprising a frame, inside which is housed a 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 device filtering device being disposed on the air flow path, preferably upstream of the engine, and a noise attenuation device disposed downstream of the engine, characterized in that said noise attenuation device comprises a cavity defined by a part of the frame and comprising, in the central part, an air outlet duct of the vacuum cleaner substantially vertical and opening, at one of its ends, outside the vacuum cleaner, its other end being disposed at the inside the cavity, said duct being free of any filtering member or deflection of the air.
  • the combination of a cavity and a duct free of any filtration or air deflection device makes it possible, in particular by changing the air passage section, but also by the continuous shape of the duct, achieve significant noise reduction efficiency.
  • the present invention thus goes against the ideas and achievements of air outlet of the vacuum cleaner where invariably, a grid and a filter called “finisher" are housed at the air outlet of the frame of the vacuum.
  • the air outlet duct is straight and has a length greater than 30 mm.
  • a linear duct and having a substantial length is favorable to calm the air flow to make the airflow as laminar as possible.
  • the air outlet duct is tubular having a diameter of between 20 and 55 mm.
  • the air outlet duct of the vacuum cleaner is preceded by an expansion chamber whose air passage surface is at least 10 times greater than the passage surface. air in the air outlet duct.
  • the duct section is constant, to keep the laminar flow.
  • the absence of a step or abrupt section break avoids the detachment of the air knives that can be source of swirls and therefore noise.
  • the flow of air entering the air outlet duct is guided, so that the channelization of the flow is gradual and soft.
  • the inlet of the air outlet duct is flared by having one or more curvatures whose radius is greater than 15 mm.
  • the portion of the frame defining the cavity comprises an inner lining of a foam-type absorbent material.
  • This efficiency is improved by arranging the absorbent material between the part of the frame and a rigid internal structure, which makes it possible, in addition to avoiding any vibration, to increase overall the wall thickness of the device, thus limiting the transparency of the walls. .
  • the frame portion delimiting the cavity is of substantially concave shape.
  • the concave shape seen with respect to the path of the air flow, makes it possible to avoid frontal shocks to said flow with respect to the walls delimiting the cavity, which limits the effects of resonance.
  • the outer air outlet mouth of the duct has an edge whose radius of curvature is less than 2 mm.
  • the architecture of the vacuum cleaner is designed so that the air outlet of the motor is substantially disposed in the extension of the air outlet duct of the vacuum cleaner.
  • the vacuum cleaner 1 consists of a vacuum cleaner body consisting of a lower body 2, an upper body 4, a lid 6 closing the housing 8 of a vacuum bag.
  • the housing 8 comprises, on its rear face, airflow communication openings with the engine compartment.
  • the lid 6 also carries the connector 10 allowing the connection between a suction pipe and the housing of the air filtration bag and storage of the vacuumed waste.
  • the rounded portion at the front of the upper body is configured as a handle 11.
  • organs 12, 14 and 16 respectively controlling the start and stop of the motor, the rewinding of the power cord, and the power of the engine.
  • the air exhaust of the engine is achieved through the subassembly 300 disposed at the rear of the apparatus, on the upper body 4.
  • the motor 20 of the vacuum cleaner is disposed in a shroud 22 in connection with an air outlet opening of the housing 8 of the bag.
  • the figure 5 shows more precisely the structure of the engine zone, in an exploded view.
  • the motor 20 is thus disposed in a shroud 22 comprising an upstream portion 202 covering the engine air inlet, made through openings 203 of the upper part 202, and a downstream part 210 covering the air outlet of the engine.
  • the fairing thus completely surrounds the engine and thus reduces the noise by the confinement thus generated.
  • a seal 216 makes it possible to seal the air inlet of the engine inside the fairing, while a seal 218 makes it possible to seal the ventilation link between the compartment 8 containing the garbage bag and the motor zone.
  • a seal 214 seals between the two parts of the fairing.
  • the lower part 210 of the fairing is pierced with a multitude openings 212 allowing the air out of the fairing. Faced with these openings is an absorbent member 230, such as a foam. This foam is disposed over substantially the entire path of the air from the fairing outlet to the outlet of the frame of the vacuum cleaner, this outlet being preceded by a passage through a filter 240, HEPA type and of the subassembly 300.
  • the lower fairing 210 of the engine, as well as the foam 230 and the HEPA filter 240 are arranged in a support 220 which is fixed on the upper fairing 202, said support thus constituting a second fairing, which, by the presented wall, makes it possible to further reduce perceived noise outside the device.
  • the openings 212 total a surface area of at least 10 cm 2 , each having an area of between 0.75 mm 2 and 40 mm 2 .
  • These openings, as shown in figure 4 are advantageously arranged in a network and located on the rear and bottom faces of the lower part of the fairing, that is to say opposite to the air outlet opening of the frame of the apparatus.
  • the vacuum cleaner comprises a device 300 for attenuating the air outlet noise of the vacuum cleaner, comprising an outer fairing 310, an inner foam 320, and an inner profile 330.
  • the shroud 310 includes clips 312 cooperating with a portion of the upper housing 4 for its maintenance vacuum.
  • the noise attenuation device 300 comprises a central duct 350 opening out of the aspirator through an opening 340 and defined by the joining of the parts 310 and 330.
  • the fairing 310 comprises a portion of the duct 314 to the duct 314. end of which are provided retaining lugs 316, six in number for the embodiment shown.
  • the fairing 310 has a dome shape 318 at the duct, reinforcing its mechanical strength.
  • the inner profile 330 has, for its part, a duct portion 332 comprising two annular ducts: a duct 3320 cooperating with the duct portion 314, and a duct 3322 of larger diameter than the duct 3320, these two ducts being connected to each other by a curved and flared portion 334 defining the inlet of the outlet duct 350.
  • conduit 3320 has an external recess for adjusting the retaining lugs 316.
  • the inner profile 330 includes holding hooks 336, cooperating with flats in the piece 310 (not shown).
  • the intermediate piece 320 is an absorbent material, such as a foam, whose shape is closest to the inner envelope of the outer fairing 310, thus providing a central opening and a dome 322, so that its attenuation effect Noise is as effective as possible by limiting uncovered areas.
  • the Figures 9 and 10 show the device 300 noise attenuation when the three parts 310, 320 and 330 are mounted.
  • the foam 320 is pressed against the inner surface of the outer fairing 310 by the inner profile 330 which is locked on the workpiece 310 by means of the hooks 336.
  • the internal profile 330 has an architecture similar to the inner envelope of the part 310, leading to the realization of the double annular conduit 3320, 3322 as previously explained.
  • the retaining lugs 316 are positioned on the outer step of the duct 3320, thus allowing the duct 350 thus formed to have a smooth internal surface, without breaking the section, which avoids generating noise.
  • the radius of curvature of the flared form 334 of air inlet in the duct 350 is of the order of 20 mm.
  • the height of the duct is approximately 45 mm, comprising a straight portion of height h close to 35 mm, and a curved portion 334.
  • the diameter d of the straight portion is approximately 35 mm.
  • the figure 11 presents, in detail, the air outlet of the duct 350.
  • the duct comprises an edge 352 having a radius of curvature as low as possible given the means used for producing this part.
  • the radius of curvature r is of the order of 1.5 mm.
  • the device 300 for attenuating the air outlet noise is thus disposed on a substantially flat portion of the upper body 4, immediately above the filter 240, thereby providing an air expansion cavity 302.
  • the volume of this cavity is about 700 cm 3 , while the volume of the duct 350 is of the order of 30 cm 3 .
  • the entry into the noise attenuation device 300 comprises an expansion of the air in the lower part of the cavity 302, constituting an expansion chamber 303 marked in dashed lines on the figure 9 .
  • the large difference in volume between the cavity 302 and the duct 350 makes it possible to create, through the cavity 302, a real aeraulic buffer.
  • the insertion of the duct 350 into the cavity, on a height j close to 30 mm, or about 2/3 of the total height of the duct, which also corresponds substantially to 2/3 of the height of the cavity 302, is the result of many attempts to find a good compromise between the size of the device and its effectiveness.
  • the passage surface in the expansion chamber 303 is at least 10 times the passage area in the conduit 350.
  • the air outlet of the engine is substantially aligned with the air outlet duct 350, thus avoiding the turbulence zones, while reducing the length of the ducts and the number of connections.
  • This alignment is conducive to obtaining a laminar flow or at least a flow having a minimum of turbulence.
  • a grid 400 in the duct 350 inserted for example at the level of the meeting.
  • ducts 314 and 3320 providing openings 402 cooperating with the retaining lugs 316.
  • Such a grid must remain acoustically inoperative, providing only a mechanical object retention function from outside the vacuum cleaner. The type of material, the structure of the grid and the mesh will be studied in this sense.
  • Such an air output noise attenuation device is advantageously used in addition to means deployed to limit other sources of noise, for example the use of a specific fairing of the motor, of foams present on the air flow path
  • An increase in the wall thicknesses of the rooms close to the aeraulic path may also be envisaged to limit the transparency of the walls so that the majority of the noise is conveyed by the aeraulic channels in order to make the best use of the device presented.
  • the Figures 13 to 16 show in particular another possible form of noise attenuation device at the air outlet of the frame of the vacuum cleaner.
  • the noise attenuation device 500 retains a generally concave shape, such as the device 300 previously mentioned, and thus has an outer fairing 510 and an inner profile 530 that locks on top of one another. by hooks 516, like the device 300.
  • the fundamental difference is relative to the air outlet opening of the frame, defined by a conduit 550 flared U-shape or smile, as best seen on the figure 15 .
  • This air outlet opening 540 of the frame is therefore devoid of filtration device, as shown in FIG. figure 15 , only a small crossbar, composed of a portion 542 from the shroud 510 and a portion 534 from the inner profile 530, connects the two edges of the conduit 550 in its middle part, to stiffen the structure.
  • This crossbar remains very discreet and affects only very little on the flow of the air flow output.
  • the device 500 with internal foam or grid, such as the elements 320 and 400 of the device 300, their presence may be necessary to improve and protect the device. in the same manner as for the device 300. Their arrangement is substantially identical to that described for the device 300.

  • the length q of the duct is of the order of 200 mm, for a neighboring width r 13 mm, so that the air passage section at the vacuum outlet is of the order of 26 cm 2 .
  • this value makes it possible to reduce the air velocities at the outlet of the vacuum cleaner, which reduces the effect of air blast which can be annoying for the user when the air speeds are high. This reduction in speed is also conducive to a reduction of the ventilation noise.
  • the air passage section of the duct 550 is between 20 and 30 cm 2 .
  • the noise attenuation device 500 also comprises an air expansion cavity 502, whose volume is slightly less than the volume of the cavity 302 of the device 300, but the difference between this volume and the volume of the duct remains sufficiently important for this cavity 502 retains airflow buffer properties as previously mentioned.
