Embodiment 1
The present embodiment provides a kind of specific embodiments of ducting assembly, as shown in Figures 1 to 5, including shell 1, wind wheel
4, volute tongue 5, deflector 6.
First side of shell 1 is equipped with air inlet 2, and air-inlet grille 9 is equipped at air inlet 2, and second side is equipped with air outlet 3,
Wind deflector 10 is equipped at air outlet 3, first side is oppositely arranged with described second side；Wind wheel 4 is arranged in the shell 1
It is interior, and between the air inlet 2 and the air outlet 3；Volute tongue 5 be set to the air outlet 3 at, the volute tongue 5 with it is described
There is gap between wind wheel 4；Deflector 6 is set to the downstream position in the airflow reflux direction of the volute tongue 5, and by described second side
Extend to the inside of the shell 1.
In the present embodiment, as shown in Figure 1, the deflector 6 is set to the lower section of the volute tongue 5.Interchangeable real
It applies in mode, deflector 6 is located at the top of volute tongue 5, and air outlet 3 is located at the lower section of volute tongue 5.
As shown in Figure 1, having gap between the deflector 6 and the volute tongue 5, setting in this way will not make the thickness of volute tongue 5
It spends greatly, to will not reduce the angle of air inlet, under the premise of guaranteeing air intake, the power of the ducting assembly is smaller.Can
In the embodiment of replacement, deflector 6 is directly contacted with volute tongue 5, very close to each other, and setting in this way can equally change incoming flow and reflux
The position that crosses, but the air-flow that will lead to reflux is too long, and wind loss is larger, and the angle of air inlet is smaller, thus to guarantee
Under the premise of same intake, spent power is larger.
As shown in Fig. 2, the volute tongue 5 close to the wind wheel 4 lower extreme point and the wind wheel 4 center line and
The angle of the line at the center of the endpoint and wind wheel 4 close to the wind wheel 4 of the deflector 6 is α, 20 °≤α≤50 °.
Such as Fig. 5, incoming flow is influenced by deflector 6, impacts the change of 6 downside rear path of deflector, far from volute tongue 5, is flowed back through deflector 6
Water conservancy diversion, the position that crosses with incoming flow is far from volute tongue 5, so as to reduce noise.
As preferred embodiment, α is 45 °.
The deflector 6 has the first face far from the volute tongue 5, the second face close to the volute tongue 5, first face
With the thickness at a distance from second face being the deflector 6, the length in first face is greater than the length in second face.From
The direction in the second face to the first face, the length of deflector 6 are gradually increased, to keep deflector 6 oblique close to the side of wind wheel 4
Face.6 pairs of reflux of deflector carry out water conservancy diversion, and making to flow back is directed away from the direction flowing of volute tongue 5, while carrying out water conservancy diversion to incoming flow,
The position that crosses for changing incoming flow and reflux, reduces the impact of air-flow, is effectively improved howling.
The length in first face is h1, and the length in second face is h2,0.25≤h2/h1≤0.5.
Further is to reduce noise, and second face is close to one end of the wind wheel 4 and the spacing of the wind wheel 4
D1, the diameter of the wind wheel 4 are D, 0.125D≤d1≤0.25D.
Using the diameter D=120mm of wind wheel 4 as specific embodiment, the difference of h1 < 60mm, h1 and h2 is C, 10mm≤
C≤15mm, the deflector 6 and the spacing of the volute tongue 5 are L1, and 40mm < L1 < 60mm will not make the thickness mistake of volute tongue 5
Greatly, to will not reduce the angle of air inlet, under the premise of guaranteeing air intake, the power of the ducting assembly is smaller.
It is equipped with air duct board 7 in the shell 1, the air duct board 7 extends close to the air outlet 3 by the air inlet 2
The air duct board 7 is the first side close to one end of the air inlet 2, and the position positioned at the surface of the wind wheel 4 is top,
It is the second side positioned at one end of the air outlet 3, the air duct board 7 is at a distance from the center of rotation of the wind wheel 4, described in
First side to the top is gradually increased.
In the rotation of the line and the top and the wind wheel 4 of the center of rotation of first side and the wind wheel 4
The angle of the line of the heart is 1≤120 ° of 1,80 °≤θ of θ, can guarantee the high efficiency outlet air of the ducting assembly.
The spacing of first side and the wind wheel 4 is a1, and the diameter of the wind wheel 4 is D, 0.03≤a1/D≤
0.09。
To guarantee that outlet air is smooth, plane, and the plane and the top are formed between the top and second side
The arc surface formed with first side is tangent.
The volute tongue 5 is top end face close to one end of the plane, and one end far from the plane is bottom face, the top
End face is inclined-plane, and from one end to the direction close to one end of the wind wheel 4 of the close air outlet 3, tilts upward and set
It sets, the angle of the inclined-plane and the plane is 2≤30 ° of 2,15 °≤θ of θ, and setting in this way keeps the angle of outlet air larger, and can
Reduce the air quantity of reflux.
The spacing of the top end face and the wind wheel 4 is a2, and the spacing of the bottom face and the wind wheel 4 is a3, a2 >
A3 can reduce the air quantity returned from the gap of volute tongue 5 and wind wheel 4, simultaneously because the spacing of top end face and wind wheel 4 is larger, energy
Enough reduce noise.
As preferred embodiment, the spacing of the volute tongue 5 and the wind wheel 4, from the top end face to the bottom end
The direction in face, is gradually reduced, and the spacing between volute tongue 5 and wind wheel 4 constantly changes, and when air-flow passes through volute tongue 5, pressure artery is different
It causes, can effectively inhibit air-flow by generating harshness when volute tongue 5, can reduce noise, and can reduce from volute tongue 5 and wind
The air quantity that the gap of wheel 4 returns.
To guarantee air intake, the company of the center of rotation of one end and wind wheel 4 close to the wind wheel 4 of the bottom face
The angle of the line of the center of rotation of line and first side and the wind wheel 4 is 3≤180 ° of 3,120 °≤θ of θ.
It is equipped with wet curtain 8 at the air inlet 2, the spacing of first side and the wet curtain 8 is L2,15mm≤L2≤
40mm, both can guarantee air intake efficiency, also can guarantee into the air in air duct without steam.
When ducting assembly in the prior art is run, as shown in figure 4, air can directly flow to the lower section of volute tongue 5, thus
It can cross near volute tongue 5 with reflux, generate howling.And the ducting assembly run when, air cools down after wet curtain 8, through into
Air port 2 enters in air duct, blows out under the action of wind wheel 4 through air outlet 3, air is filled after entering in air duct in shell 1, part
Air cannot be directly impinging the lower section of volute tongue 5 by the blocking of deflector 6, and deflector 6 carries out water conservancy diversion to the air of the part,
Make it away from volute tongue 5, at the same have partial air can the clearance backflow through volute tongue 5 Yu wind wheel 4, deflector 6 can to reflux carry out
Water conservancy diversion makes the position that crosses of reflux and incoming flow far from volute tongue 5, so as to reduce noise.
Embodiment 2
