According to some embodiments of the present invention, on the flow direction of air-flow, the second wind wheel 6 is located at the upper of the first wind wheel 4
Trip.It is understood that can control when air-conditioner outdoor unit 100 switches to off-mode from open state positioned at the second wind
The first wind wheel 4 rotation in 6 downstreams is taken turns, to realize the removing of the dust stratification on heat exchanging device 9.
According to some embodiments of the present invention, as shown in Figure 2 and Figure 4, on the flow direction of air-flow, the second wind wheel 6
In the downstream of the first wind wheel 4.It, can be with it is understood that when air-conditioner outdoor unit 100 switches to off-mode from open state
The first wind wheel 4 that control is located at 6 upstream of the second wind wheel rotates, to realize the removing of the dust stratification on heat exchanging device 9.
According to some embodiments of the present invention, as shown in figure 4, the direction of rotation of the first wind wheel 4 and the second wind wheel 6 is opposite.
Thus, it is possible to promote the first wind wheel 4 and the second wind wheel 6, work efficiency is high, reduces the work of the first wind wheel 4 and the second wind wheel 6
Energy consumption can reduce the operating power of the first wind wheel 4 and the second wind wheel 6, advantageously reduce in the case where discharge quantity of fan is certain
The work noise of first wind wheel 4 and the second wind wheel 6.
It should be noted that when air-conditioner outdoor unit 100 is in and works normally, the rotation of the first wind wheel 4 and the second wind wheel 6
Contrary, when air-conditioner outdoor unit 100 is in deashing state, the direction of rotation of the first wind wheel 4 and the second wind wheel 6 is also opposite.
Specifically, the first wind wheel 4 and the second wind wheel 6 are along air flow direction use front and back arrangement, under the premise of flow is constant
Can be with hoisting wind pressure, and then promote air supplying distance.
For example, in some examples of the invention, the blade of the inclined direction of the blade of the first wind wheel 4 and the second wind wheel 6
Inclined direction on the contrary, and the direction of rotation of the first wind wheel 4 and the direction of rotation of the second wind wheel 6 it is opposite.
It is understood that the inclined direction phase of the blade of the inclined direction of the blade of the first wind wheel 4 and the second wind wheel 6
Instead, the first wind wheel 4 and the second wind wheel 6 guide vane each other on the direction that air flows, reduces that (the first wind wheel 4 and the second wind wheel 6 exist
In the case where different revolving speeds) or to eliminate (the first wind wheel 4 and the second wind wheel 6 are in the case where identical revolving speed) air-flow tangential
Rotation speed (static pressure is converted by dynamic pressure), improve the mechanical efficiency to whirlwind wheel to air, and pass through two wind
The air-flow of wheel is flowed towards the direction of air outlet 1212, to realize the effect blown at a distance.
It should be noted that compared to single cross flow fan, axial flow blower or diagonal flow fan, to the first wind in whirlwind wheel
Wheel 4 and either reverse rotation or the identical velocity reversal rotation at different rates of the second wind wheel 6, can to whirlwind wheel
Realize more air-supply at a distance.
According to some embodiments of the present invention, as shown in Figure 2 and Figure 4, air-conditioner outdoor unit 100 (referring to Fig.1) further includes
One wind collecting unit 7, the first wind collecting unit 7 are set in the outside of the second wind wheel 6 (referring to Fig. 3).First wind collecting unit 7 has collection wind to air-flow
With the effect of rectification, under the action of the first wind collecting unit 7, the flow direction of the air-flow of the outer edge of the second wind wheel 6 can be more
The rule added, while the leakage vortex of the outer edge of the second wind wheel 6 can also be weakened, so as to promote the smooth of air-flow flowing
Property, and then the working efficiency of air-conditioner outdoor unit 100 is promoted, the work noise of air-conditioner outdoor unit 100 is reduced, promotes what user used
Comfort.
Further, as shown in Figure 2 and Figure 4, the diameter of the second wind wheel 6 is D1 (D1 as shown in Figure 2), the first wind collecting unit
The minimum spacing of 7 inner wall and the second wind wheel 6 is L1 (L1 as shown in Figure 2), and L1 meets: 0.01≤L1/D1≤0.03.It can
It is D1 by the diameter of the minimum spacing L1 and the second wind wheel 6 of the inner wall of the first wind collecting unit 7 and the second wind wheel 6 with understanding
Ratio be set between 0.01-0.03, not only can to avoid the second wind wheel 6 in the course of rotation with the first wind collecting unit 7 send out
Raw interference, can also further weaken the blade tip leakage vortex of the second wind wheel 6, to further weaken pneumatic noise, further
Promote the reliability that air-conditioner outdoor unit 100 works.
It should be noted that meeting when the minimum spacing L1 of the inner wall of the first wind collecting unit 7 and the second wind wheel 6 is greater than 0.03D1
Leaf top leakage vortices breakdown is caused to become larger, aerodynamic noise can also increase with it；When the inner wall and the second wind wheel 6 of the first wind collecting unit 7
The gap minimum spacing L1 it is smaller when, the first wind collecting unit 7 then be easy collides with the second wind wheel 6, while influence collection wind effect.
For example, shell 1 includes front panel 13 in Fig. 1 and embodiment shown in Fig. 2, the first wind collecting unit 7 is fixed on front
