With reference to Fig. 1, Fig. 2 and Fig. 8, in the utility model embodiment, centrifugal wind wheel 10 includes blade seat 11, air inducing circle
12 and two ends multiple blades 13 of being connected with described blade seat 11 and described air inducing circle 12 of correspondence, described blade 13 has company
Meet the interior lateral margin 13a and lateral border 13b of the two ends setting of described blade 13, the thickness of described blade 13 is in described interior lateral margin 13a
It is in tapered setting towards on the direction of described lateral border 13b.
Specifically, when this centrifugal wind wheel 10 rotates, air enters from air inducing circle 12, then by the blade 13 rotating by sky
Conductance goes out.Air by blade 13 interior lateral margin 13a towards in the lateral border 13b moving process of blade 13, due to blade 13 this
Plant tapered setting, blade 13 has guide effect to air, so that the rate travel of air is faster, resistance is less；Identical
In time, more air can be derived by this centrifugal wind wheel 10 from blower fan.Thus increasing the air output of blower fan.
The technical solution of the utility model is passed through to make improvements the blade 13 of centrifugal wind wheel 10, so that the thickness of this blade 13 is existed
In it, lateral margin 13a is in tapered setting towards on the direction of its lateral border 13b, and blade 13 has to the air entering air inducing circle 12 leads
To effect, so that the resistance of Air blowing is reduced, such that it is able to improve the air output of blower fan, and then can improve this is installed
The air output of the cabinet air-conditioner of centrifugal wind wheel 10.
With reference to Fig. 3 and Fig. 8, blade 13 lateral margin 13a from it is in the tool of tapered setting towards on the direction of its lateral border 13b
Body embodiment can be：Blade 13 from it lateral margin 13a towards the curved setting of lateral border 13b, or blade 13 is from it
Lateral margin 13a is linearly arranged towards lateral border 13b.In one embodiment, in order to reduce further centrifugal wind wheel 10 windage,
Described blade 13 extends straight from described interior lateral margin 13a towards described lateral border 13b.So, air is in two plates of blade 13
Can flow directly out on face, two plate faces the movement of this air will not bring resistance.
See figures.1.and.2, due to because blade 13 combination of odd number can bring more property than blade 13 combination of even number
Can advantage.If once blade 13 quantity designs for even slice, and if forming symmetrical arrangement mode, then not only make leaf
Piece 13 balance of itself is difficult to adjust, and blade 13 can produce more resonance, thus leading to blade 13 long-time
Bear the fatigue that resonance produces, blade 13 finally occurs and ruptures.Therefore, in the present embodiment, the quantity of blade 13 is odd number.Separately
Outward, the quantity of usual blade 13 can not be excessive, nor very few.Blade 13 excessively can lead to spacing between two blades 13 too
Little, the speed that impact air flows through between two blades 13；Blade 13 is very few, and the vacuum that blade 13 inner side is formed is inadequate, air
The amount entering air inducing circle 12 is less, thus affecting air output.In one embodiment, the quantity of blade 13 is preferable at 7 to 15
Embodiment.
With reference to Fig. 6 and Fig. 7 it is contemplated that blade 13 can directly affect air output with the radial direction corner dimension of air inducing circle 12, folder
Angle is excessive, and it is less that blade 13 rotates the vacuum producing；Angle is too small, and the spacing between blade 13 is less.Therefore, angle bigger than normal or
Less than normal all can lead to air output reduce.In a further preferred embodiment, in order that the air output of centrifugal wind wheel 10 is sufficiently large, described
Blade 13 is 20 ° to 25 ° with the radial direction angle α of described air inducing circle 12.
Under table 1 same rotational speed, the corresponding air output of different α value
As shown in Table 1, when 10 ° to 15 °, air output is in 1203～1233m for α value3Between/h, air output is relatively low.When α value
When 20 ° to 25 °, air output is in 1386～1422m3Between/h, air output is higher.When α value is at 30 ° to 35 °, air output exists
992～1230m3Between/h, air output relatively low it can be seen that, only α be 20 ° to 25 ° when, air output can be maximized.
In the case that the external diameter of air inducing circle 12 is certain, the width of blade 13 can not be excessive, nor too small.This be because
For if blade 13 width is excessive, on the one hand larger resistance, another aspect air can be caused to the rotation of whole centrifugal wind wheel 10
Can not flow out between two blades 13 rapidly, this also can cause to the flowing of air to hinder.If the width of blade 13 is too small, leaf
It is less that piece 13 rotates the vacuum producing.Therefore, above-mentioned two situations all can reduce the air output of centrifugal wind wheel 10.Preferable one
In embodiment, equally in order to increase the air output of centrifugal wind wheel 10, the external diameter of described air inducing circle 12 is D, including described blade 13
The span (namely width of blade 13) of lateral margin 13a to lateral border 13b is 0.15D to 0.25D.
With reference to Fig. 2, in a further preferred embodiment, in order to increase the air output of centrifugal wind wheel 10, described blade further
Seat 11 includes connecting the base plate 11a of described blade 13, and is located at the axle connecting portion 11b in the middle part of described base plate 11a, described air inducing
Circle 12 includes outer ring and inner ring, the distance between described outer ring and described base plate 11a less than described inner ring and described base plate 11a it
Between distance.So, between the end of interior lateral margin 13a of each blade 13 and the inner surface of air inducing circle 12, there is gap, centrifugation
During wind wheel 10 rotation, air not only can flow to lateral border 13b between the interior lateral margin 13a of two blades 13, can also be from blade
13 end flows between two blades 13, so that air can flow through rapidly between two blades 13, increased air output.
See figures.1.and.2, on the basis of a upper embodiment, in order to increase the air output of centrifugal wind wheel 10, institute further
State air inducing circle 12 in described outer ring towards curved setting on the direction of described inner ring.So, the interior lateral margin 13a of each blade 13
End and the inner surface of air inducing circle 12 between space bigger, more air can be accommodated and enter, such that it is able to improve this
The air output of centrifugal wind wheel 10.
With reference to Fig. 5, in the case that the race diameter of air inducing circle 12 is certain, the inner ring diameter of air inducing circle 12 is crossed conference and is led to
Blower effect is poor；The inner ring diameter of air inducing circle 12 is too small, and the amount that air enters can be led to inadequate.In the present embodiment, in order to
Ensure the blower effect of air inducing circle 12, a diameter of D of the outer ring of described air inducing circle 12, inner ring diameter is 0.7D to 0.8D.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
Change, or directly/be indirectly used in other related technical fields and be included in scope of patent protection of the present utility model.
