Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most identical
Or similar label represents same or similar element or has the element of same or like function.Retouch below with reference to accompanying drawing
The embodiment stated is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
Describing air draft assembly 100 according to embodiments of the present invention referring to Fig. 1-Fig. 2, this air draft assembly 100 generallys include:
Exhaust duct 10 and resonance silencer 20.Wherein, the entrance of the exhaust duct 10 of air draft assembly 100 is connected with spiral case 40, with
Exhaust duct 10 is made to turn on spiral case 40.
Defining chamber in spiral case 40, spiral case 40 is provided with the air inlet with chamber conducting and air outlet, exhaust duct 10 and air-out
Mouth is connected.Being provided with impeller in chamber, impeller rotates under the driving of motor and flows to air outlet direction from air inlet to be formed
Air-flow, and discharged by exhaust duct 10.
As it is shown in figure 1, be formed with vent 11 on the tube wall of exhaust duct 10, the tube wall of the through exhaust duct of vent 11 10.
Resonance silencer 20 is the closed cavity shape with opening, and the opening of resonance silencer 20 is connected with vent 11 so that being total to
The deafener 20 that shakes turns on exhaust duct 10, and resonance silencer 20 seals vent 11, resonance silencer 20 and exhaust duct
10 combinations form the ventilating noise reduction knot of the sealing making air-flow be entered and to be discharged by the outlet of exhaust duct 10 by the entrance of exhaust duct 10
Structure.
It is to say, the import of the vent 11 of exhaust duct 10 is connected with the air outlet of spiral case 40, resonance silencer 20
Opening communicates with vent 11, and air-flow flows out from the outlet of vent 11, does not flows out from resonance silencer 20, when air-flow stream
When moving resonance silencer 20 with exhaust duct 10 junction, owing to acoustic impedance suddenlys change, resonance silencer 20 can eliminate air-flow
The acoustic energy that middle frequency of sound wave is identical or close with the natural frequency of resonance silencer 20, fraction acoustic energy and resonance silencer 20
Inwall frictional damping be converted into heat energy and disappear, only small part acoustic energy continue propagate forward.
Thus, air draft assembly 100 according to embodiments of the present invention, by arranging and being total to that the vent 11 of exhaust duct 10 is connected
Shake deafener 20, so that resonance silencer 20 and exhaust duct 10 combination form ventilating noise reduction structure, ventilating noise reduction structure
Can effectively eliminate major part sound wave produced by air current flow, thus reduce the purpose that air-flow wind is made an uproar.
In some embodiments of the invention, air draft assembly 100 also includes connecting tube 30, and one end week of connecting tube 30 is along with logical
The week in air port 11 is along being tightly connected, and the week of the other end of connecting tube 30 is along the opening week with resonance silencer 20 along the company of sealing
Connect.
The noise reduction principle of the air draft assembly 100 of above-described embodiment is as follows, and resonance silencer 20 is regarded as a lumped parameter
System, and ignore the acoustic wave movement in resonance silencer 20.Former in order to be more clearly understood from the work of resonance silencer 20
Reason, can regard as piston by the air in connecting tube 30, and it has certain acoustic mass；Resonance silencing cavity is regarded as air bullet
Spring, it has certain acoustic compliance；Air vibrate in connecting tube 30 and and connecting tube 30 wall between produce friction and damping
Effect, it has certain acoustic resistance.Thus acoustic mass, acoustic compliance and acoustic resistance just constitute acoustic vibration system at gas channel.Work as air draft
When in pipe 10, air-flow flows in vent 11, when the sound wave in air-flow arrives the junction of connecting tube 30 and exhaust duct 10,
Air in connecting tube 30 has the trend (can regard as air slide compressed air spring) to resonance silencing cavity internal vibration,
When the frequency of sound wave in air-flow with contain the natural frequency of vibrational system close to time, acoustic impedance is undergone mutation so that big in air-flow
Part acoustic energy is reflected back, and the inwall frictional damping of fraction acoustic energy and resonance silencer 20 is converted into heat energy and disappears,
Only have small part acoustic energy to continue to propagate forward.In other words, acoustic vibration system can consume identical with its natural frequency with air-flow
The acoustic energy of sound wave, thus play and reduce the purpose that air-flow wind is made an uproar.
Wherein, connecting tube 30 can be welded with resonance silencer 20, bolt is connected, threaded or one-body molded.I.e. connect
Adapter 30 can be connected by welding manner is fixing with resonance silencer 20, and connecting tube 30 and resonance silencer 20 can also
Detachably connected by bolt or engagement thread.Certainly, connecting tube 30 can also be by integrally becoming with resonance silencer 20
Type mode is fixing to be connected, thus meets the demand of various processes.
Additionally, connecting tube 30 and exhaust duct 10 can also be connected by welding, bolt, threaded or one-body molded.I.e.
Connecting tube 30 and exhaust duct 10 can be connected by welding manner is fixing, connecting tube 30 and exhaust duct 10 can also bolt or
Screw thread removably connects, or connecting tube 30 can also be connected by one-body molded mode is fixing with exhaust duct 10, from
And meet the demand of various processes.
In some embodiments of the invention, the shape that resonance silencer 20 is little in opening size and interior space dimension is big.I.e.
From the opening internally direction in space of resonance silencer 20, air-flow is less than the stream in inner space in the circulation area of opening part
Logical area.The change of circulation area makes acoustic impedance undergo mutation, such that it is able to by frequency of sound wave in air-flow and resonance silencer
Identical or the close acoustic emission of the natural frequency of 20 goes back, and then reaches to eliminate the purpose that air-flow wind is made an uproar.
Alternatively, in the plane being perpendicular to opening axis, the area of the inner space of resonance silencer 20 and aperture area
Ratio is in the range of 1 to 10.Thus, it is possible to the sound wave in guarantee air-flow can be gone back by effectively launching, thus enter one
Step reduces the operating noise of air draft assembly 100.
In one particular embodiment of the present invention, on the direction away from exhaust duct 10 of the axis along opening, resonance silencer
The area of the inner space in 20 cross sections being perpendicular to opening axis is gradually increased, is gradually reduced, first increases and then decreases or first reduce
Rear increase.I.e. the ventilation area of resonance silencer 20 can be gradually increased, be gradually reduced, first increases and then decreases or first subtract
The gradual change type modes such as little rear increase change.As long as can ensure that the acoustic energy effectively consumed in sound wave reduces air-flow in exhaustor
Noise.
Alternatively, on resonance silencer 20, arbitrary place is perpendicular to area and the aperture area of the inner space in the cross section of opening axis
Ratio be all higher than two points to three.The i.e. ventilation area of opening part and the air circulating face of resonance silencer 20 inner space
Long-pending change is in sudden change formula change, as long as can ensure that the acoustic energy effectively consumed in sound wave reduces the noise of air-flow in exhaustor
?.It is only illustrative it is understood that above-mentioned, is not the restriction to the embodiment of the present invention, the face of inner space
Long-pending and aperture area ratio can also be other ratios.
Additionally, resonance silencer 20 can cylinder body shape in hollow, the rectangular shape of hollow, the spherical or hollow of hollow
Irregularly shaped.It is only signal it is understood that above-mentioned, is not the restriction to the embodiment of the present invention.
