Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention is described.
As shown in Figure 1-Figure 3, the fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention, comprising: the first wind
Take turns the 21, second wind wheel 22 and driving assembly 3.
Wherein, the first wind wheel 21 includes multiple the first blades 211 being spaced apart in its circumferential direction, the second wind wheel 22
Including multiple the second blades 221 being spaced apart in its circumferential direction.On the circulating direction of air draught, the second wind wheel 22
The downstream of the first wind wheel 21 can be located at and the second wind wheel 22 can be spaced with the first wind wheel 21 and be arranged.Driving assembly 3 can divide
Do not cooperate with the first wind wheel 21 and the second wind wheel 22 to drive the first wind wheel 21 and the second wind wheel 22 to rotate.
Specifically, since the first wind wheel 21 and the second wind wheel 22 can be oppositely arranged on the direction of airflow, the
One wind wheel 21 and the second wind wheel 22 can organize pairs of whirlwind wheel, and the first wind wheel 21 and the second wind wheel 22 all can be axial-flow windwheels.
When fan assembly 2 works, driving assembly 3 can respectively drive the first wind wheel 21 and the rotation of the second wind wheel 22, the first wind wheel 21
Direction of rotation with the second wind wheel 22 can be opposite.The air-flow circumference of the blade exit of multiple first blades 211 is tangentially fast as a result,
It spends opposite with the air-flow circumference tangential velocity of blade exit of multiple second blades 221 and can partly or entirely cancel out each other,
It is hereby achieved that the straight air-flow of approximate pure " axial direction ", i.e., most of or even whole air draughts can be along fan assembly 2
Axial direction blowout, it is possible thereby to increase the air output and air supplying distance of fan assembly 2, and then can promote fan assembly 2
Air supply efficiency.
It is understood that compared to single tubular wine wheel, axial-flow windwheel or oblique flow wind wheel, to first in whirlwind wheel
Wind wheel 21 and the second wind wheel 22 can rotate simultaneously, it is possible thereby under the premise of driving assembly 3 consumes identical power, to whirlwind
Air output maximum, the air supply efficiency highest of wheel.Therefore, under the premise of meeting identical air output requirement, to the consumption of whirlwind wheel
Electricity is also minimum.Therefore, the fan assembly 2 in the present invention can play a dual role of promoting air supply efficiency and reduce energy consumption,
With extremely strong practical performance.
As shown in Fig. 2, the first wind wheel 21 can be along the development length of its axial direction (front-rear direction as shown in Figure 2)
L1, the second wind wheel 22 can be L along the development length of its axial direction2, spacing L between the first wind wheel 21 and the second wind wheel 220
It can satisfy relational expression: 0.2 (L1+L2)≤L0≤1.5(L1+L2).Specifically, when fan assembly 2 is rotated, the first leaf
The tail portion of piece 211 and the second blade 221 is since rotation swing flap will form leaf top leakage whirlpool, wherein the tail portion of the first blade 211 can
To be interpreted as the part close to the second blade 221 of the first blade 211, the tail portion of the second blade 221 can be understood as the second leaf
Part of the piece 221 far from the first blade 211.It the leaf top leakage whirlpool that first blade 211 generates can be with the when passing through the second wind wheel 22
Two blades 221 collide, and thus can generate bigger noise.
It is understood that working as L00.2 (L of <1+L2) when, the spacing between the first wind wheel 21 and the second wind wheel 22 is smaller,
Leaf top leakage whirlpool can be circulated to the second wind wheel 22 after generating in a short period of time, thus act on the second blade 221
Impact force is larger, to generate biggish noise.Work as L01.5 (L of >1+L2) when, between the first wind wheel 21 and the second wind wheel 22
Spacing is excessive, and the velocity of liquid assets loss for the air-flow that the first wind wheel 21 generates is larger, to reduce the air-supply effect of fan assembly 2
Rate.As 0.2 (L1+L2)≤L0≤1.5(L1+L2), the spacing setting between the first wind wheel 21 and the second wind wheel 22 is more reasonable, the
The intensity in the leaf top leakage whirlpool that one blade 211 generates can reduce during being circulated to the second wind wheel 22 from the first wind wheel 21,
It is possible thereby to reduce the impact force acted on the second blade 221, the noise of the generation of fan assembly 2 can be reduced.Moreover, at this time
Spacing between first wind wheel 21 and the second wind wheel 22 is smaller on the influence of the air supply velocity of fan assembly 2, so as to ensure wind
The air supply efficiency of thermomechanical components 2.
In specific example as shown in fig. 8, the development length L along its axial direction of the first wind wheel 211=60mm, the
The development length L along its axial direction of two wind wheels 222=40mm is controlled respectively between the first wind wheel 21 and the second wind wheel 22
Spacing size (L0=20mm, L0=30mm, L0=40mm) and detect the noise content that fan assembly 2 generates under different spacing.From
In chart shown in fig. 8 as can be seen that under the premise of fan assembly 2 generates identical air quantity, L0=20mm, that is, L0=0.2
(L1+L2) when the noise that generates of fan assembly 2 it is maximum, L0=30mm, that is, L0=0.3 (L1+L2) when fan assembly 2 generate noise
Compared to L0=0.2 (L1+L2) when the noise that generates have and significantly reduce, lower noise about 2.0dB (A).L0=40mm, that is, L0
=0.4 (L1+L2) when the noise that generates of fan assembly 2 it is minimum, L0=0.3 (L1+L2) arrive L0=0.4 (L1+L2) between noise drop
Low amplitude is far smaller than L0=0.2 (L1+L2) arrive L0=0.3 (L1+L2) between lower noise amplitude.
The fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention, by being arranged in air draught circulating direction
On the first wind wheel 21 and the second wind wheel 22 that are spaced apart, can play a dual role of promoting air supply efficiency and reduce energy consumption,
The practical performance of fan assembly 2 can be promoted.By controlling 0.2 (L1+L2)≤L0≤1.5(L1+L2), need of blowing can met
The noise that fan assembly 2 generates is reduced under the premise of asking, so as to promote the usage comfort of user.
According to some embodiments of the present invention, the spacing L between the first wind wheel 21 and the second wind wheel 220Can further it expire
Sufficient relational expression: 0.3 (L1+L2)≤L0≤1.5(L1+L2).It is verified through inventor's test of many times, as 0.3 (L1+L2)≤L0≤1.5
(L1+L2) when, fan assembly 2 not only can satisfy air-supply demand, but also fan assembly 2 generates the smaller of noise.Optionally, L0
It can be 0.5 (L1+L2), L0It may be 0.8 (L1+L2), L0It can also be (L1+L2).As shown in figure 3, according to the present invention one
