One end of 12a, described blade root 12b connects described wheel hub 11, and the other end of described blade root 12b connects described blade portion 12a,
The thickness of described blade root 12b is gradually reduced on the direction towards described blade portion 12a.
Specifically, it is provided with axial flow blower in cabinet air-conditioner, axial flow blower has motor, movable vane wind wheel, outer cover, movable vane wind
Wheel is installed on the air intake of outer cover, and stator blade wind wheel 10 is installed on the outlet air end of outer cover, motor connection movable vane wind wheel.Work as axial flow blower
During operation, motor drives the rotation of movable vane wind wheel, and the air outside cabinet air-conditioner is guided stator blade wind wheel 10, Jing Guojing by movable vane wind wheel
The rectification after-blow of blade wind-wheel 10, to the outlet frame of cabinet air-conditioner, is finally derived by outlet frame.
Because the space between two adjacent blade root 12b is less, so air-flow, when blade root 12b, is also easy to produce and makes an uproar
Sound；Especially when air is after being guided out by movable vane wind wheel, air-flow is in disorder, when the flow velocity of air-flow is between two blade root 12b
Little when big, when flow velocity is excessive, noise will be produced.And in the present embodiment, with reference to Fig. 3, the blade root 12b due to fan blade 12 is
In tapered setting, when air-flow flows through fan blade 12, fan blade 12 has collecting effect to air, and air has towards blade root
The trend of the junction flowing of 12b and blade portion 12a, so, this fan blade 12 1 aspect can by air-flow in disorder for flow direction,
And the inconsistent air-flow extremely of flow velocity reintegrates, so that air-flow is when stator blade wind wheel 10 flows out, flow velocity is more uniform, direction one
Cause, so, the noise that air-flow produces also accordingly reduces；On the other hand, by the backstop action of fan blade 12, the outlet air end of outer cover
Effectively air-out area is less, is equivalent to fan blade 12 and air-flow is pressurized, thus blowing farther by the air-flow that stator blade wind wheel 10 is derived.
For proving the noise reduction of this fan blade 12, make following Experimental comparison：
Table 1 is that existing stator blade wind wheel is arranged at each experiment parameter contrast table in air-conditioner

Unrelated.In addition, the power even with the cabinet air-conditioner of stator blade wind wheel in the utility model is larger, the little all the better (ginseng of its noise
According to Tables 1 and 2).
The technical solution of the utility model is passed through to set up a blade root between the blade portion 12a and wheel hub 11 of fan blade 12
12b, and, the thickness of described blade root 12b is gradually reduced on the bearing of trend of fan blade 12, and air-flow flows to two blade root 12b
Between when, progressively towards the junction flowing of blade root 12b and blade portion 12a, stator blade wind wheel 10 is reintegrated to air-flow, makes axle
Flow fan air-out evenly property, noise is lower.
With continued reference to Fig. 3, on the basis of above-described embodiment, in order that fan blade 12 is bigger to the integration dynamics of air-flow, with
Make the flow velocity of air-flow evenly, in the present embodiment, the thickness of described blade portion 12a is being directed away from described blade root 12b's
It is gradually increased on direction.So, when movable vane wind wheel is by air-flow guiding stator blade wind wheel 10, air-flow is in stator blade wind wheel 10 radially
It is divided into two parts, a part is located between two adjacent blade portion 12a, a part is located between two adjacent blade root 12b, two
Air between blade root 12b can be towards the junction flowing of blade root 12b and blade portion 12a, between two blade portion 12a
Air can also flow towards this junction, so that the rectification effect of this fan blade 12 is more preferably.

So with the vibration of fan blade 12, the junction of blade portion 12a and blade root 12b is easy to rupture.But if blade portion 12a
Span less, the span of blade root 12b is larger, then it is just less that the thickness of blade root 12b reduces gradient, is so unfavorable for whole
Stream.In the present embodiment, on the one hand in order to improve the bulk strength of fan blade 12, on the other hand also for the rectification ensureing fan blade 12
Effect, the radial span of this stator blade wind wheel 10 is L, and blade root 12b is 0.2L～0.4L in the radial span of this stator blade wind wheel 10.
With continued reference to Fig. 4 it is contemplated that expanding with heat and contract with cold, the end of fan blade 12 can not be too near with wheel cover 13, and leaf must not be too far away, too
Closely may result in fan blade 12 to abut with wheel cover 13, cause wheel cover 13 to deform；Wheel cover 13 and fan blade 12 end far may be led to very much
Between leak out, thus affecting rectification effect.In the present embodiment, a diameter of D of the wheel cover 13 of described stator blade wind wheel 10, described wheel
The distance between the axis of hub 11 and end of described fan blade 12 areSo, even if fan blade 12 is heated
Expand, the end of fan blade 12 also will not be abutted with the inwall of wheel cover 13；In addition, fan blade 12 end with will not be with wheel cover 13 inwall
