It is connect with third air duct part 950.Thus, it is possible to multiple air ducts be arranged on same air duct mounting plate 920, so as to increase wind
Road quantity promotes air output.
According to some embodiments of the present invention, on air-out direction, the first fan assembly 9101 is located at the second fan assembly
9102 downstream, the depth that the motor 9103 of the first fan assembly 9101 is located at corresponding installation cavity 911 are greater than the second blower fan group
The motor 9103 of part 9102 is located at the depth of corresponding installation cavity 911.It should be noted that can be according in air conditioner 9100
Portion's structure selects reasonable evacuation, for example, different fitting depths is arranged in two motors on air-out direction, on the one hand may be used
So that be located at the motor of upstream has reasonable evacuation inside the motor 9103 and air conditioner 9100 of the second fan assembly 9102
On the other hand space can also shorten motor positioned at downstream in the fitting depth of the motor 9103 of the second fan assembly 9102
(" depth " here refers to the distance that motor is located in installation cavity 911 on air-out direction), so as to save installation space.
As shown in Figure 8, Figure 9, air conditioner 9100 according to an embodiment of the present invention, including ducting part as described above 900.
Specifically, air conditioner 9100 may include casing 9110, and casing 9110 is equipped with air inlet and air outlet, air duct portion
Part 900 can be located at air outlet.
Air conditioner 9100 according to an embodiment of the present invention, by installation cavity 911 being arranged on wheel hub 91 to be used to accommodate electricity
Machine 9103, that is to say, that on the axis direction of wheel hub 91, motor 9103 is at least partly overlapped with wheel hub 91, it is possible thereby to
Reduce size of the fan assembly 910 on 91 axis direction of wheel hub to keep away so as to reduce the overall volume of ducting part 900
Exempt from that motor 9103 is excessive to be exposed to inside air duct 923, and then the wind noise of air conditioner 9100 can be reduced, promotes air conditioner
9100 air output.
Air conditioner 9100 according to an embodiment of the present invention is described in detail with specific embodiment below.It should be noted that
It is described below to be merely illustrative, rather than to specific restriction of the invention.
Embodiment 1
In this embodiment, on the direction of the rotation axis of wheel hub 91, the height of blade 92 is H, on blade 92 with wheel
The point of the rotation axis lie farthest away of hub 91 is located on circle of reference, is D1 with reference to diameter of a circle.It is test H and D1 to air conditioner
The influence of 9100 air quantity noises is tested by taking D1=360mm, 800 side's air quantity as an example, is tested as follows:
Table 1
As seen from the above table, as 0.05≤H/D1≤0.5, the wind noise of air conditioner 9100 is small, low energy consumption.When 0.05≤
When H/D1≤0.5, the volume of fan blade 9 can also be reduced.
Embodiment 2
In this embodiment, on the direction of the rotation axis of wheel hub 91, the height of blade 92 is H, on blade 92 with wheel
The point of the rotation axis lie farthest away of hub 91 is located on circle of reference, is D1, the first fan assembly 9101 and the with reference to diameter of a circle
Vertical range between two fan assemblies 9102 is L4.Influence for test L4 to 9100 noise of air conditioner, with D1=360mm, H
It tests, tests as follows for=44mm, 1200 side's air quantity:
Table 2
As seen from the above table, as 0.025≤L4/D1≤0.16, the wind noise of air conditioner 9100 is small, low energy consumption.
Embodiment 3
In this embodiment, on the direction of the rotation axis of wheel hub 91, the height of blade 92 is H, on blade 92 with wheel
The point of the rotation axis lie farthest away of hub 91 is located on circle of reference, is D1 with reference to diameter of a circle, blade 92 and electric machine support 921 it
Between minimum range be L3.
Influence for test L3 to 9100 noise of air conditioner, carries out by taking D1=360mm, H=44mm, 1200 side's air quantity as an example
Test is tested as follows:
Table 3
For L3, verified by theoretical and test, L3 is smaller, and the air quantity with the fan assembly of revolving speed is bigger, same to wind
It is lower to measure lower fan noise, it is contemplated that assembly, transport and fan operation error that may be present or deformation, in order to avoid wind
Leaf and air duct inner wall are interfered, and L3 should not be too large, also unsuitable too small.
Due to 360mm 921 manufacturing tolerance of electric machine support be ± 2mm, so, as L3=2mm, be easy to cause fan blade with
It is interfered between 921 inner wall of electric machine support.In consideration of it, in the present embodiment, L3 >=3mm.
From table 3 it can be seen that corresponding level of noise is 51.3dB as L3=15mm, it is very close to 50dB, so
This, L3 is preferred values within the scope of 3mm to 15mm.
In addition, level of noise rises slowly during it can also be seen that L3 is gradually increased to 10mm by 2mm in table 4, and
When L3 increases to 10mm by 8mm, level of noise increases comparatively fast, is based on this, preferably 6mm≤L3≤10mm, mm, most preferably 7mm.
Further, as 0.025≤L3/D1≤0.15, it on the one hand can reduce ducting part 900 in 91 axis of wheel hub
Thickness on direction；On the other hand, it can also avoid interfering or colliding between blade 92 and electric machine support 921, so as to
To reduce the operation noise of ducting part 900.Further, wherein 0.025≤L3/D1≤0.15.It as a result, on the one hand can be with
Reduce thickness of the ducting part 900 on 91 axis direction of wheel hub；On the other hand, blade 92 and electric machine support can also be avoided
It interferes or collides between 921, so as to reduce the operation noise of ducting part 900.
