The wind-guiding component of indoor environment is delivered to including centrifugal blower and with the air flow guiding for blowing out centrifugal blower.This field skill
Knownly, centrifugal blower includes spiral case and the impeller 2211 that is arranged in spiral case to art personnel.Wherein spiral case includes common limits
Go out the spiral case peripheral wall of two spiral case side walls 2212 of two spiral case side walls 2212 and connection in spiral case air duct.Spiral case peripheral wall includes opposite
Volute section 2213a in 2211 outer profile flaring of impeller and the volute tongue that is each extended over out from the both ends of volute section 2213a
Section 2213b and exit zone 2213c, and the wind turbine of centrifugal blower is formed between volute tongue section 2213b and exit zone 2213c
Air outlet.
Wind-guiding component is defined from fan outlet to the diversion air duct extended away from the direction of impeller 2211, and is configured to
The air-flow blown out from fan outlet is exported forward.Particularly, the exit zone 2213c of centrifugal blower is located at its volute tongue section
The front side of 2213b.The forward direction side wall and backward side wall of diversion air duct be set as respectively along the preceding crest curve that protrudes backward and to
The rear crest curve group protruded afterwards extends, and two lateral sidewalls are set as vertically extending, to reduce noise and wind-guiding wind
The center of the air outlet in road and the air-flow velocity difference of edge.
Before making the present invention, those skilled in the art think, centrifugal blower, to air work, makes gas by impeller 2211
Body is rotated and is moved out under the influence of centrifugal force, and therefore, the diversion air duct being connected to the spiral case air duct of centrifugal blower only has
Can just it make gas in air duct relative to the extension of the outer profile flaring of impeller 2211 identically as the extending direction in spiral case air duct
Flowing is more smooth, reduces the noise because of air-flow and the collision generation of air duct inner wall.However, present inventor passes through to water conservancy diversion
The geomery in air duct has carried out a large amount of debugging, creatively finds, diversion air duct is designed as prolonging for elder generation and spiral case air duct
Direction is stretched in the same manner again reversely to prolong relative to the outer profile flaring of impeller 2211 relative to the extension of the outer profile flaring of impeller 2211
It stretches, flowing stroke of the gas in diversion air duct can extended, keeping the gas blown out from centrifugal blower abundant in diversion air duct
While mixing, keep the flowing of gas smooth, not only have lower noise, but also from the center of the air outlet in wind-guiding air duct with
The flow velocity difference of the air-flow of edge blowout is smaller, has preferable user experience.
In some preferred embodiments, centrifugal blower preferably uses Double suction type centrifugal wind motor, i.e. two spiral case side walls 2212

Angle (volute tongue angle) α of 2213b2For 50 °~70 °, and/or the angle α of volute tongue section 2213b and fan outlet3For 53 °~
63 ° of centrifugal blower.For example, the angle α of volute tongue section 2213b and exit zone 2213c1For 19 °, volute section 2213a
The angle α of the tangent line and volute tongue section 2213b most nearby of pivot center away from impeller 22112For 57 °, volute tongue section 2213b
With the angle α of fan outlet3It is 58 °.
Referring to Fig. 1, in some currently preferred embodiments of the present invention, diversion air duct 223 can be set to from centrifugal blower 221
Fan outlet extends to the direction flaring far from impeller 2211, to improve the static pressure for the air-flow for flowing through diversion air duct 223, to
Improve the flow rate of gas.Preceding crest curve can be included at least puts down from close to impeller 2211 to far from 2211 direction of impeller successively
It slips over and crosses connection and circular arc on front side of the first front side circular arc, the second front side circular arc and third that radius is sequentially reduced.Crest curve afterwards
Can include at least from close to impeller 2211 to far from 2211 direction of impeller be successively smoothly connected and radius is sequentially reduced the
Circular arc on rear side of one rear side circular arc, the second rear side circular arc and third improves the stream of gas with the smoothness that further gas flows
Dynamic rate.Wherein the first front side circular arc and the first rear side circular arc may be configured as to the direction away from impeller 2211 and extend back.
Circular arc may be configured as to away from impeller 2211 on front side of circular arc, the second front side circular arc and third on front side of second front side circular arc, third
