Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model air purifier fan assembly lower cover is described in further detail.
As shown in Figure 1, the utility model air purifier fan assembly lower cover, centrifugal blower 30 is arranged in lower cover body 10, lower cover body 10 is also provided with wind deflector 20, wind deflector 20 is arranged around centrifugal blower 30 lower edge, its two ends connect with the inwall of lower cover body 10 both sides and the air outlet of position and lower cover body 10 is relative, after entering the air in clarifier and being centrifuged blower fan 30 discharge, can scatter to surrounding, the effect of wind deflector 20 be exactly like the air of the air outlet of lower cover body 10 dorsad stop by wind deflector 20, and flow towards the air outlet of lower cover body 10 again along the radian of wind deflector 20.
Wherein wind deflector 20 is made up of interconnective arc section 21 and bevel phase 22.Gap between arc section 21 and centrifugal blower 30 is gradual change type design.Gap namely between arc section 21 and centrifugal blower 30 is by the narrow transition structure broadened, and from gap, the less transformation larger to gap is identical with the direction of rotation of turbine centrifugal blower fan 30, namely first the air thrown away from centrifugal blower 30 enters in less gap and discharges from larger gap, along with the gap between arc section 21 and centrifugal blower 30 becomes large gradually, make the speed goes of air slow, going out speed and can not produce more noise finally when reaching outlet.
In addition, the bevel phase 22 of wind deflector 20 opposite side is connected with lower cover body 10 opposite side inwall, when from gap, larger end flows out air, there is the air of part can be back to lower cover body 10 opposite side, at this moment, bevel phase 22 just can by the air " bounce-back " of backflow, and the angle α between the bevel phase 22 of wind deflector 20 and lower cover body 10 sidewall is less than or equal to 45 degree, allow backflow air down cover board body 10 air outlet direction derive, avoid because inwall bounce-back and make wind direction cause the situation of sinuous flow.
Centrifugal blower 30 produce eddy current wind action under, the direction that certainly will the trend of wind will be caused to rotate towards centrifugal blower along the outlet of wind deflector 20 arc section 21 is got rid of, thus cause the throughput of air outlet side to be far longer than the throughput of opposite side, uneven and the sinuous flow of such two sidewinds also will certainly produce noise, in order to reduce noise further, air outlet place on lower cover body 10 is provided with the first wind comb 41 and the second wind comb 42 of two uniform intervals settings, each wind comb place plane respectively and the angle formed between the sidewall of lower cover body 10 can design along the outlet wind direction angle of wind deflector 20 arc section 21.Concrete, angle β between first wind comb 41 and lower cover body 10 sidewall is less than or equal to 45 degree, first wind comb 41 is reverse design with the angle of bevel phase 22, form closed loop whereby, after the eddy current wind that centrifugal wind 30 machine produces collides bevel phase 22 and the closed loops that formed of the first wind comb 41, the air outlet combed between 42 towards the first wind comb 41 and the second wind equably blows out, enable the air quantity that wind deflector 20 arc section 21 exports on average to be cut, form shunting more in order to air can be discharged from lower cover body 10 air outlet as far as possible more fifty-fifty, reduce the possibility producing noise because air mass flow is uneven.
And the end of wind comb is the design of circle lead angle, also ensure that when cutting steam, can not produce windage and air noise, again reduce issuable noise.Certainly, the quantity of wind comb can increase to some extent according to the width of outlet air surface, and length and angle adjust to some extent according to different air outlets.
The utility model air purifier fan assembly lower cover arranges evenly spaced wind comb in the air outlet of lower cover body, not only decile air-flow, water conservancy diversion is carried out to the air of discharging simultaneously, air can more smoothly be discharged from the air outlet of lower cover, thus reduce the generation of noise.And design the wind deflector of circular arc at the lower edge of lower cover centrifugal blower, to allow air concentrate on one end air-out.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
