The path outside shell 10 is passed to out of shell 10, thus prevent noise directly through behind the gap between two blades 2282 from into
Stomata 122 passes to outside pedestal 20.
Referring to Fig. 10, the bladeless fan 100 of embodiment of the present invention includes the pedestal 20 of any of the above-described embodiment.
In the bladeless fan 100 of embodiment of the present invention, due to being provided with the of covering air inlet 214 in shell 10
One acoustical panel 221, and the noise that dynamical system 21 generates can be reflected back in dynamical system 21 by the first cambered surface 222, in this way
The noise that dynamical system 21 issues when working can shift to an earlier date before spreading to air inlet 121 by 221 multiple reflections of the first acoustical panel
And consumed, in this way, the noise that dynamical system 21 issues when working is effectively reduced.
In the bladeless fan 100 of embodiment of the present invention, as shown in figure 12, curve a is that bladeless fan 100 omits noise reduction
Sound pressure level curve when component 22, curve b are sound pressure level curve when bladeless fan 100 is provided with noise reduction component 22.Wherein, it indulges
Coordinate SPL indicates the sound pressure level of the noise of bladeless fan 100, and abscissa f indicates the frequency of the noise of bladeless fan 100.By scheming
12 as can be seen that the sound pressure level of the noise of bladeless fan 100 declines when being provided with noise reduction component 22 in shell 10.
In one embodiment, bladeless fan 100 includes fan head 30.Fan head 30 is formed with air duct (not shown go out) and even
The nozzle 31 of ventilating duct.Fan head 30 be connected to pedestal 20 with dynamical system is generated air-flow feeding air duct in and through nozzle 31 to
Outer injection.
Further, it fans in the air duct of head 30 and is provided with foam.Generated in air duct make an uproar can be absorbed in foam as a result,
Sound, so as to reduce the noise of bladeless fan 100.
The part that fan head 30 upwardly extends is curvilinear, so that air duct is curvilinear, it is possible thereby to when lowering air flowing
The noise of generation.
Incorporated by reference to Figure 11, junction of the air-flow between dynamical system 21 and fan head 30 is leaked in order to prevent, bladeless fan
100 include sealing element 40.Sealing element 40 is tightly connected dynamical system 21 and fan head 30.
Specifically, in order to keep the air-out effect of bladeless fan 100 preferable, fan head 30 is generally long compared with pedestal 20, this makes air-flow
Path to air duct is longer, and resistance is larger, and the curved shape in air duct can make path longer, resistance is bigger.If lacking sealing element
40, it since the path length resistance in air duct is big, can be easy to make reverse flowing of air flows in the cavity of pedestal 20, form very big wind and make an uproar, and
And air-out effect is poor.The setting of sealing element 40 can then solve so that in gluing, sealing state between dynamical system 21 and fan head 30
The above problem.
In one example, between shore A40~60, elasticity is moderate to stretch the hardness of sealing element 40.Preferably,
Sealing element can be silica gel sealing hose.
In one example, sealing element 40 includes upper end 41 and lower end 42.Upper end 41 is tightly connected fan head 30.Lower end 42 is in
Cone expansion structure can be packed into directly outside the rectification circle 21a of dynamical system 21, with the air outlet of sealed motive force system 21
215b.Sealing element 40 is tightly connected dynamical system 21 and fan head 30 by upper and lower ends in this way.
As shown in the dotted arrow of Fig. 2, when bladeless fan 100 works, the motor 213 of dynamical system 21 drives impeller 212
Rotation, air successively pass through air inlet 121 and air inlet 214 and are sucked by impeller 212, after air is accelerated pressurization by impeller 212
High pressure draught is formed, high pressure draught successively enters after gas passage 216a and diffuser 215 in the air duct of fan head 30, finally
It is sprayed from nozzle 31, so that the high pressure draught that nozzle 31 sprays can roll up the air around inhaling, so that wind is formed, to be embodied as using
The effect of family cooling.Diffuser 215 includes the rectification circle 21a and stator blade 215a in rectification circle 21a.
In addition, the revolving speed of motor 213 gradually increases, out of service in bladeless fan 100 when bladeless fan 100 starts
When, the revolving speed of motor 213 gradually decreases, it is possible thereby to make bladeless fan 100 slowly starting and it is out of service, so as to drop
The vibration of low bladeless fan 100, to reduce the generation of noise.
