Definitions

the invention relates to a removable muffler for hair dryer and a hairdryer equipped with such a muffler.
the invention relates to the technical field of accessories for hair dryers (or dryers) and more particularly the removable silencers to reduce their noise.
the hair dryers generally comprise at least one housing 10 comprising an inlet end 11, an outlet end 12.
a motor M disposed inside the housing 10, rotates at least one propeller T (or fan , or turbine) sucking air through at least one inlet 110 at the inlet end 11, upstream of said propeller and expelling it downstream, by at least one outlet orifice 120 at the outlet end level 12.
Resistance type heating means (not shown) is disposed downstream of the helix T, so as to heat the expelled air through the outlet port 120.
the black arrows schematize the circulation of the air flow.
a cover 3 is fixed at the inlet end 11, upstream of the inlet orifice 110. This cover 3 makes it possible to avoid access to the rotating parts of the propeller T and to protect the dryer. hair from fouling due to dust and hair.
the cover 3 usually includes a filter 30 for retaining all or part of the dust and hair.
the cover 3 can be fixed or removable, allowing in the latter case its disassembly and quick reassembly to facilitate the cleaning and / or replacement of the filter 30.
a problem in the field of hairdryers relates to the often high noise level of the motor M and the propeller T.
the noise generated by such devices is a source of significant harm to the user.
the main objective of the invention is to provide a muffler whose installation / uninstallation is easier and faster than the mufflers known from the prior art.
the solution proposed by the invention is a hair dryer silencer, comprising a chamber provided with at least one air inlet orifice and at least one air outlet orifice, one or more elements of attenuation being arranged in said chamber to attenuate the sound vibrations associated with a flow of air between said inlet port and said outlet port.
This muffler is remarkable in that it comprises fixing means configured so that said muffler can be fixed on the filter hood of a hair dryer, said fixing means being removable fixing means.
the removable fixing means are arranged around the air outlet orifice of the chamber.
the muffler comprises fixing means configured so that said muffler can be fixed on the filter hood of a hair dryer, said fixing means being removable fixing means.
the silencer object of the invention is intended to equip a hair dryer or a dryer, whether used by an individual or a professional. It reduces the noise generated by such a device.
the hair dryer is of the type described above with reference to the figure 1 . It is provided with a filtration cover 3 fixed at the inlet end 11, upstream of the inlet orifice 110.
the cover 3 is generally made of plastic. It comprises an opening 31 for the passage of air, disposed opposite the inlet orifice 110, said opening being protected by a filter 30.
the latter is for example formed of a grid and / or an open cell foam filter material.
the cover 3 is preferably removably attached to facilitate the cleaning and / or the replacement of the filter 30.
the cover 3 is for example fixed by clipping, screwing or interlocking on the housing 10, at the inlet end 11
the means for removably attaching the cover 3 to the housing 10 are different from the means for removably attaching the muffler 2 to said cover, as described later in the description.
the cover 3 can however be permanently attached to the housing 10.
the silencer 2 which is the subject of the invention is in particular formed of a hollow envelope 200 comprising a lateral wall, a front wall and a bottom wall delimiting an internal chamber 20.
the casing 200 is made of a relatively rigid plastic material of the type High Density Polyethylene, Polyvinyl Chloride, Polycarbonate, or any other material suitable for the skilled person.
the chamber 20 may have a substantially cylindrical, frustoconical, spherical, or other shape, and a substantially circular, oval, polygonal, and so on.
the chamber 20 has a substantially frustoconical shape and a substantially circular section.
the chamber 20 is provided with at least one air inlet port 210 and at least one air outlet port 220.
the air outlet orifice 220 is a circular opening made in the front wall of the casing 200, said orifice being coaxial with the axis X of the chamber 20.
the air outlet orifice 220 is arranged so as to be arranged vis-à-vis the opening 31 of the cover 3 when the muffler 2 is mounted on the hair dryer.
the air outlet orifice 220 of the silencer 2, the opening 31 of the cover 3 and the inlet orifice 110 of the casing 10 are coaxial and have substantially the same shape.
the air inlet orifice or openings 210 are arranged radially around the chamber 20, around the circumference of the envelope 200. Such an arrangement makes it possible to obtain an air inlet surface greater than that obtained with a axial arrangement of the type described in the patent document WO 2009/112690 (VELECTA PARAMOUNT).
the air inlet ports 210 are formed in the side wall of the casing 200. They can be made in the form of rectangular slots, circular openings, or other.
the air inlet in the chamber 20 is radial.
the bottom wall of the casing 200 preferably has a concave shape oriented towards the inside of the chamber 20, so that the flow of air penetrating radially through the orifices 210 is channeled longitudinally along the X axis. towards the air outlet orifice 220 ( figure 2 ).
each attenuation element 24 is in the form of an annular ring of acoustic absorbing material and has a central hole 240 whose shape comprises a plurality of radial points 241 equidistant angularly from each other. These radial points 241 are directed towards the center of the chamber 20, providing the passage of the air flow a larger contact area.
the outer diameter of the annular ring 24 is substantially equal to the internal diameter of the chamber 20 and the diameter of the central hole 240 substantially equal to the diameter of the air outlet orifice 220.
Stoppers 201 can be provided on the inner walls. of the chamber 1 to ensure the proper positioning of the attenuation element 24.
the latter are preferably made of a porous material of the polyurethane foam type. Their dimensions and / or the material used, are tuned to the sound frequencies to be attenuated. The user can thus have at his disposal several attenuation elements 24 of different design, each element being intended for a model of hairdryer.
the attenuation elements 24 can easily be introduced into the chamber 20 via the air outlet orifice 220, especially in the case where they are made of a flexible and deformable material.
the inner wall of the chamber 20 may be directly shaped to attenuate the sound vibrations associated with the air flow therethrough.
the muffler 2 comprises means 23 for removable attachment configured so that said muffler can easily be attached to the hood 3 of the hair dryer.
the cover 3 is now interposed between the casing 10 and the silencer 2.
the means 23 for fixing the silencer 2 are advantageously arranged around the air outlet orifice 220 and are configured to cooperate with complementary fixing means 33 arranged around the opening 31 of the cover 3.
Other configurations are of course conceivable.
the means 23 for fixing the silencer 2 are in the form of one or more tabs projecting outwardly from the chamber 20 and each having a bead 230 configured to be removably housed in a recess 33 made on the around the inner wall of the opening 31 of the cover 3 and forming complementary fixing means.
the section of the recess 33 is complementary to the section of the beads 230, so that said beads engage in said recess when the user pushes the silencer 2 against the cover 3 and said beads disengage said recess when the user exerts traction on said silencer.
Other means of fastening equivalent by clipping for example clipping couplings activated by snap, can obviously be used by those skilled in the art.
the fixing means 23 may also be in the form of a threaded tubular portion 230 'adapted to be screwed into a complementary threaded tubular portion 33' of the opening 31 of the cover 3, or vice versa.
This screw connection can for example be configured so that the user can assemble / disassemble the muffler 2 of the cover 3, by manipulating said muffler 1 ⁇ 4 or 1 ⁇ 2 turn.
Other equivalent fastening means by screwing can obviously be used by those skilled in the art.
the muffler 2 can still be fixed by interlocking on the cover 3, for example by providing a bayonet type connection for securing said muffler to said cover.
the envelope 200 may also comprise a portion 230 "shaped to fit snug against an outer wall of the hood 3 ( figure 5 ).
Other equivalent fastening means by interlocking can obviously be used by those skilled in the art
the silencer 2 is advantageously provided with a skirt 21 extending beyond the air outlet orifice 220 of the chamber 20 and surrounding the envelope 200.
this skirt 21 is configured to form a seal between the air outlet orifice 220 and the housing 10. In this way, all (or almost all) of the air flow from the chamber 20 enters the housing 10 through the air inlet 110.
the skirt 21 is preferably made of a material different from that of the casing 200 and in particular a softer material.
the skirt 21 may for example be made of flexible rubber or silicone. The use of a flexible material allows the skirt 21 to perfectly match the shape of the housing 10 when the muffler 2 is fixed on the cover 3 and form a sealed connection.
the skirt 21 can be fixed by gluing, clipping, screwing, interlocking, or other, on the envelope 200.
