The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings it is described in detail ducting assembly according to embodiments of the present invention.
As shown in Fig. 2 ducting assembly according to embodiments of the present invention, including：Spiral case 10, centrifugal blower 20 and annular wind-guiding
Pipe 30.
Specifically, centrifugal blower 20 is located in spiral case 10.Advantageously, the molded line of spiral case 10 is spiral of Archimedes.
Annular guide duct 30 has main air inlet 301 and main air outlet 302.The air outlet of main air inlet 301 and spiral case 10
101 connections.Advantageously, main air inlet 301 and main air outlet are relative about 302.Arranged for interval is additionally provided with annular guide duct 30
Multiple secondary air outlets 305.
Ducting assembly according to embodiments of the present invention, centrifugal blower realizes the speed-raising pressurization of air-flow in spiral case, warp
Spiral case diffusion and laggard promoting the circulation of qi stream circulation conveying is stablized in flow field, can effectively reduce aerodynamic noise, lift users' satisfaction degree.
According to the example of the present invention, the part structure of the inner ring of annular guide duct 30 towards the air outlet 101 of spiral case 10
Cause the first bending wind deflector 303 bent outwardly.Thus, it is possible to be carried out to the air-flow exported by the air outlet 101 of spiral case 10
Distribution.
Advantageously, as shown in Fig. 2 in the horizontal plane, the projection of the bending part of the first bending wind deflector 301 and centrifugal blower
The projection interval predetermined distance d at 20 center.Further, the predetermined distance d can be 10mm.
That is, the position on the top of the first bending wind deflector 301 has important to the ratio of distribution of air flow and direction
Influence.In view of the offset characteristic of the air-out direction of centrifugal blower 20, the position on the top of the first bending wind deflector 301 should be with centrifugation
The center of blower fan 20 is offset slightly from.As shown in Fig. 2 centrifugal blower 20 is according to rotationally clockwise, then the first bending wind deflector
The position on 301 top is located at the left side 10mm at the center of centrifugal blower 20.
According to the example of the present invention, the inner ring of annular guide duct 30 is configured to court towards the part of main air outlet 302
Second bending wind deflector 304 of outer bending.Advantageously, center of the bending part of the second bending wind deflector 304 just to main air outlet.
Thus, air-flow enters after being distributed at main air inlet 301 through the first bending wind deflector 302 in the main body of annular guide duct 30, portion
Air-flow is divided to be flowed out at secondary air outlet 305.When residual gas stream is reached at main air outlet 302, through the second bending wind deflector 304
Collect again, flowed out from main air outlet 302.
Ducting assembly according to embodiments of the present invention, centrifugal blower realizes the speed-raising pressurization of air-flow in spiral case, warp
Enter after spiral case diffusion and flow field stabilization in annular guide duct, through main air outlet and secondary air outlet progress air-flow conveying, and pass through
First bending wind deflector, the second bending wind deflector, the reasonable Arrangement of main air outlet and secondary air outlet realize effective distribution of air-flow,
Distribution of air flow and reduction aerodynamic noise can be effectively improved.
When ducting assembly according to embodiments of the present invention is arranged on the refrigeration plants such as refrigerator, refrigerator, showcase,
Aerodynamic noise is low, and distribution of air flow rationally, greatly improves the user satisfaction of user.
