The element that same or similar label represents same or similar element or has same or like function.Below with reference to attached
The embodiment of figure description is exemplary it is intended to be used for explaining the present invention, and is not considered as limiting the invention.
The axial-flow windwheel 100 of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Figure 17.
As shown in figure 1, the axial-flow windwheel 100 of embodiment according to a first aspect of the present invention, including:Outer wheel hub 11, inner wheel hub
12nd, multiple outer leafs and multiple intra vane 3.Here, it should be noted that " interior " can be understood as towards axial-flow windwheel 100
The direction of center of rotation, its rightabout is defined as " outward ", that is, away from the direction of axial-flow windwheel 100 center of rotation.
With reference to Fig. 1, inner wheel hub 12 is located in outer wheel hub 11, and multiple outer leafs are located on the periphery wall of outer wheel hub 11, and many
Along the circumferentially spaced arrangement of outer wheel hub 11, multiple intra vanes 3 are located at the internal perisporium of inner wheel hub 12 and outer wheel hub 11 to individual outer leafs
Between, and multiple intra vane 3 is along the circumferentially spaced arrangement of inner wheel hub 12.Alternatively, the center of inner wheel hub 12 and outer wheel hub 11
Dead in line, thus the wind wheel being made up of intra vane 3 and inner wheel hub 12 and the wind wheel being made up of outer leafs and outer wheel hub 11
Center of rotation identical so that the air-supply of axial-flow windwheel 100 is more concentrated.
Specifically, as shown in figure 1, inner wheel hub 12 generally open at one end, the cylindrical shape of other end closing, outer wheel hub 11 is big
Body is the cylindrical shape of both ends open, and inner wheel hub 12 is contained in outer wheel hub 11, and multiple outer leafs are from the periphery wall edge of outer wheel hub 11
Extending radially outwardly of outer wheel hub 11, the inner end edge of multiple intra vanes 3 and the outer end edges periphery with inner wheel hub 12 respectively
Wall be connected with the inner circumferential wall of outer wheel hub 11 that is to say, that multiple intra vane 3 from the periphery wall of inner wheel hub 12 along lubrication groove
The periphery wall extending radially outwardly to outer wheel hub 11 of hub 12, outer wheel hub 11 is connected with inner wheel hub 12 by multiple intra vanes 3.
Thus, inner wheel hub 12 is directly connected using intra vane 3 with outer wheel hub 11, reduces axial-flow windwheel 100 complex structure
Degree, is easy to process and assembles, and improve the intensity of axial-flow windwheel 100, and in addition it also avoid may using other attachment structures
Impact to the flow field of axial-flow windwheel 100 is it is ensured that axial-flow windwheel 100 has excellent aeroperformance.In addition, axial-flow windwheel 100
Compact conformation, good integrity, shared structure space is less so that axial-flow windwheel 100 be particularly well-suited to air-supply away from
Have, from to shared structure space, the occasion being distinctly claimed, for example, be applied to air-conditioner outdoor unit 1001 or indoor apparatus of air conditioner 1002
Deng.
Certainly, the invention is not restricted to this, intra vane 3 can also be only connected with the periphery wall of inner wheel hub 12, and not with outward
The inner circumferential wall of wheel hub 11 be connected that is to say, that multiple intra vanes 3 from the periphery wall of inner wheel hub 12 along the footpath of inner wheel hub 12
To stretching out and the inner circumferential wall of outer end edges and outer wheel hub 11 of intra vane 3 keeps certain interval (not shown).
Further, with reference to Fig. 1, multiple outer leafs can be evenly distributed on the periphery wall of outer wheel hub 11, also
It is to say, the angle between two outer leafs of arbitrary neighborhood can be equal, and multiple intra vane 3 can be evenly distributed in lubrication groove
That is to say, that the angle between two intra vanes 3 of arbitrary neighborhood can be equal on the periphery wall of hub 12.
Certainly, the invention is not restricted to this, multiple outer leafs can also be non-uniformly distributed on the periphery wall of outer wheel hub 11
(not shown) is that is to say, that the angle between two outer leafs of arbitrary neighborhood can be unequal, and multiple intra vane 3
The folder that is to say, that between the two of arbitrary neighborhood intra vanes 3 can be unevenly distributed on the periphery wall of inner wheel hub 12
Angle can be unequal.
So, due to intra vane 3 and the outer leafs of inside and outside distribution can be arranged on axial-flow windwheel 100 simultaneously, such that it is able to
Intra vane 3 and outer leafs are arranged respectively to different types, to improve the air-supply effect of axial-flow windwheel 100.
For example in an example of the present invention, the leaf of intra vane 3 can be under relatively low motor speed
The blade (small hub for example hereinafter described is than propeller type axial blade 2000) of enough air circulation flows can be provided, outward
The leaf of blade can be from blade (the such as hereafter institute that can improve delivery air total head under relatively low motor speed
The big hub stated is than axial blade 3000), thus the air-supply air-flow of intra vane 3 and outer leafs can be under axial-flow windwheel 100 air-supply
Cross at trip, the air-flow that this crosses has being more favorably oriented property, and will not dissipate, and then effectively increase air supplying distance,
Additionally do not improve motor speed, on the premise of additionally not improving the air-supply power of axial-flow windwheel 100, effectively improve axle stream
The aeroperformance of wind wheel 100.Wherein, the concept such as motor speed is well known to those skilled in the art, and I will not elaborate.
Further, with reference to Fig. 2 and Fig. 3, along the axial direction of axial-flow windwheel 100, the rotation of intra vane 3 and outer leafs
Plane can be approximately in same plane, thus intra vane 3 can be same in the same plane with the air intake of outer leafs and air-out
Step is carried out, and there is not the air-flow causing due to range difference in the axial direction of axial-flow windwheel 100 of intra vane 3 and outer leafs and interferes
Problem, thus not existing due to the possible impact that externally blade working produces of intra vane 3 off-design operating mode work, does not also exist
The impact that intra vane 3 work may be produced due to the work of outer leafs off-design operating mode, and then improve axial-flow windwheel 100
The stability of aeroperformance, and remain to obtain good air-supply effect so that axle stream in axial-flow windwheel 100 off-design operating mode
Wind wheel 100 is more favorable for the popularization and application in Practical Project.In addition, reducing design difficulty, reduce production cost.
Axial-flow windwheel 100 according to embodiments of the present invention, by arranging intra vane 3 with outward on axial-flow windwheel 100 simultaneously
Blade, such that it is able to carry out effective cutting to the air-out air trajectory of axial-flow windwheel 100 entirety, thus effectively improve axle stream
The air-out effect of wind wheel 100 is so that axial-flow windwheel 100 can take into account air supplying distance and air-supply power.
In one embodiment of the invention, multiple outer leafs include multiple first outer leafs 21 and multiple second outer leafs
22.With reference to Fig. 1, multiple first outer leafs 21 are from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11 and many
The shape of individual first outer leafs 21, size all same, the established angle on outer wheel hub 11 also identical it is preferable that work as multiple first
When outer leafs 21 are evenly distributed on outer wheel hub 11, multiple first outer leafs 21 can be by first outer leafs 21 with foreign steamer
Centered on the central axis of hub 11, axle, annular array obtain, and now multiple first outer leafs 21 are with respect to coaxial inner wheel hub 12
It is distributed with being centrosymmetric with the central axis of outer wheel hub 11.
With reference to Fig. 1, multiple second outer leafs 22 from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11,
And the shape of multiple second outer leafs 22, size all same, the established angle on outer wheel hub 11 also identical it is preferable that when multiple
When second outer leafs 22 are evenly distributed on outer wheel hub 11, multiple second outer leafs 22 can by second outer leafs 22 with
Centered on the central axis of outer wheel hub 11, axle, annular array obtain, and now multiple second outer leafs 22 are with respect to coaxial lubrication groove
The central axis of hub 12 and outer wheel hub 11 is distributed with being centrosymmetric.
Need exist for illustrating, as shown in figure 1, the rotor diameter that multiple first outer leafs 21 are constituted with outer wheel hub 11
The rotor diameter that multiple second outer leafs 22 are constituted can be equal to outer wheel hub 11 that is to say, that the footpath of the first outer leafs 21
Equal with the radical length of the second outer leafs 22 to length.Certainly, the wind that multiple first outer leafs 21 are constituted with outer wheel hub 11
Wheel diameter can also be without equal, i.e. the first outer leafs 21 with multiple second outer leafs 22 and the rotor diameter that outer wheel hub 11 is constituted
Radical length unequal with the radical length of the second outer leafs 22.
Preferably, the blade shape of the first outer leafs 21 is different from each other with the blade shape of the second outer leafs 22.For example,
One outer leafs 21 are different from the type of the second outer leafs 22, or, the first outer leafs 21 are identical with the type of the second outer leafs 22,
And the first outer leafs 21 are different from the aerodynamic configuration of the second outer leafs 22.Here, it should be noted that according to wind wheel design special
Industry term, " type of blade is identical " can be understood as the value of " specific speed " of blade place wind wheel substantially in identical numerical value
Interval, such as all in 100 magnitudes, 200 magnitudes etc., and " aerodynamic configuration is different " of blade can be understood as blade place wind wheel
" specific speed " value substantially in identical numerical intervals, but because the difference of blade construction details, and make wind wheel " than turning
The concrete value of speed " is different.
When the vane type of the first outer leafs 21 and the second outer leafs 22 is not it is preferred that with reference to Fig. 1, the first siphonal lobe
Piece 21 is that routine lacks the small hub of blade than propeller type axial blade 2000, and the second outer leafs 22 compare axle for multiple-blade big hub
Stream blade 3000, wherein, with reference to Fig. 9, " small hub ratio propeller type axial blade " refers to the axle stream wind with small hub ratio
The blade of wheel, wherein small hub is more general than referring to the hub diameter of wind wheel and the smaller of wind wheel integral diameter, ratio range
It is less than or equal to 0.2, such axial-flow windwheel typically has less blade, and can be during the blade working of such axial-flow windwheel
Enough air circulation flows are provided under relatively low motor speed;With reference to Figure 10, " big hub is than axial blade " refers to
There is the blade of the axial-flow windwheel of big hub ratio, wherein big hub than refer to wind wheel hub diameter and wind wheel integral diameter it
Ratio is larger, and ratio range is typically greater than equal to 0.4, and such axial-flow windwheel typically has more blade, and such axle stream wind
The blade of wheel can improve the total head of delivery air under relatively low motor speed.
When the first outer leafs 21 are identical with the type of the second outer leafs 22, but the first outer leafs 21 and the second outer leafs 22
Aerodynamic configuration different when, alternatively, the first outer leafs 21 and the second outer leafs 22 are conventional small hub than propeller type axle
Stream blade 2000, or it is the blade tip portion (will be described below) that conventional small hub is than propeller type axial blade 2000,
Or alternatively, the first outer leafs 21 and the second outer leafs 22 are big hub than axial blade 3000, but, the first outer leafs
21 can be different from the concrete aerodynamic configuration of the second outer leafs 22.Here, it should be noted that outside the first outer leafs 21 and second
The species of blade 22, aerodynamic configuration and constituted mode are not limited to mentioned above.
As shown in Figure 1-Figure 3, when the first outer leafs 21 be conventional small hub than propeller type axial blade 2000, and second
Outer leafs 22 be big hub than axial blade 3000 when, the first outer leafs 21 can be conventional small hub than propeller type axle stream leaf
The blade tip portion of piece 2000.During specific configuration, small hub can be from the periphery wall of inner wheel hub 12 than propeller type axial blade 2000
Face extends radially outwardly along inner wheel hub 12, and extends to the outside of outer wheel hub 11, by small hub than propeller type axle stream leaf
The part between outer wheel hub 11 and inner wheel hub 12 of piece 2000 is considered as the leaf that small hub is than propeller type axial blade 2000
Root, by small hub, than propeller type axial blade 2000, the part positioned at outer wheel hub 11 outside is considered as small hub and compares propeller
The blade tip portion of formula axial blade 2000, gives up the blade root that small hub is than propeller type axial blade 2000, and retains small hub
Than propeller type axial blade 2000 blade tip portion as the first outer leafs 21, such that it is able under relatively low motor speed
Enough air circulation flows are provided.
However, the second outer leafs 22 can be the entirety that big hub is than axial blade 3000, during specific configuration, with reference to Fig. 1,
Big hub can so will from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11 than axial blade 3000
Big hub is than collectively regarded as second outer leafs 22 of axial blade 3000.
Thus, when the first outer leafs 21 are the blade tip portion that conventional small hub is than propeller type axial blade 2000, and second
Outer leafs 22 be big hub than axial blade 3000 entirety when, the radical length of the first outer leafs 21 and the second outer leafs 22 can
With identical when that is to say, that the rotor diameter of wind wheel that constituted of the first outer leafs 21 and outer wheel hub 11 and the second outer leafs 22
Can be identical with the rotor diameter of the wind wheel that outer wheel hub 11 is constituted.Thus, by being made than axial blade 3000 using big hub
For the second outer leafs 22, and the second outer leafs 22 are arranged on the periphery wall of peripheral speed highest outer wheel hub 11, thus
The total head of delivery air can be improved under relatively low motor speed, and air-supply noise will not be caused to increase, also will not lead
The frictional dissipation increase of air-flow, power is caused to increase, and then air-supply noise and the power of axial-flow windwheel 100 can be reduced.
Further, reference Fig. 1, the first outer leafs 21 and the second outer leafs 22 are alternately arranged along the circumference of outer wheel hub 11.
Specifically alternatively, it is provided with least one second outer leafs 22 between two the first outer leafs 21 of arbitrary neighborhood, and often adjacent
The quantity of the second outer leafs 22 between two the first outer leafs 21 can be different.
Alternatively, the quantity of the second outer leafs 22 is N times of the quantity of the first outer leafs 21, and wherein N is more than or equal to 1
Positive integer.That is, the quantity of the second outer leafs 22 is equal with the quantity of the first outer leafs 21, or the second outer leafs 22
Quantity is the positive integer times of the quantity of the first outer leafs 21, now, when the first outer leafs 21 and the second outer leafs 22 are along outer wheel hub
When 11 circumference is equably alternately arranged, the number of the second outer leafs 22 being provided between two the first outer leafs 21 of arbitrary neighborhood
Amount is identical, further, when the shape all same of multiple first outer leafs 21, and the shape all same of multiple second outer leafs 22
When, the overall central axis with regard to outer wheel hub 11 of outer leafs is centrosymmetric.
For example in the example of fig. 1, outer wheel hub 11 is provided with three the first outer leafs 21 and six the second outer leafs 22, often
It is provided with two the second outer leafs 22, now the quantity of the second outer leafs 22 is outside first between two adjacent the first outer leafs 21
Two times of the quantity of blade 21, when three the first outer leafs 21 and six the second outer leafs 22 are respectively about in outer wheel hub 11
When heart axis is centrosymmetric, the overall central axis with regard to outer wheel hub 11 of outer leafs is centrosymmetric, thus improve wind wheel
Run stability.
Certainly, the invention is not restricted to this, the first outer leafs 21 and the second outer leafs 22 can also be without the week along outer wheel hub 11
To be alternately arranged that is to say, that can be not provided between two the first outer leafs 21 of arbitrary neighborhood the second outer leafs 22 or
It is provided with least one second outer leafs 22.
Thus, by setting small hub on the periphery wall of outer wheel hub 11 than propeller type axial blade 2000 and big
The two kinds of blade of hub ratio axial blade 3000, and two kinds of blades are alternately arranged along the circumference of outer wheel hub 11, due to slight
Hub ratio propeller type axial blade 2000 is more identical than the center of rotation of axial blade 3000 with big hub but respective exit flow
Velocity differ, thus along air conveying direction, the air-flow that two kinds of blades drive can be handed at axial-flow windwheel 100 downstream
Converge and common discharge so that the directionality of the air-flow that crosses are more preferable forward, it is to avoid the Divergent Phenomenon of air-flow, effectively increase and send
Wind distance.
In one embodiment of the invention, with reference to Fig. 1, multiple intra vanes 3 be connected to outer wheel hub 11 and inner wheel hub 12 it
Between, and the shape of multiple intra vane 3, size all same, the established angle on inner wheel hub 12 also identical it is preferable that when multiple interior
When blade 3 is evenly distributed on inner wheel hub 12, multiple intra vanes 3 can be by an intra vane 3 with the central shaft of inner wheel hub 12
Centered on line, axle, annular array obtain, and now multiple intra vanes 3 are with respect to the central shaft of coaxial inner wheel hub 12 and outer wheel hub 11
Line is distributed with being centrosymmetric.
Alternatively, intra vane 3 is identical with the quantity of the first outer leafs 21.For example in the example of Fig. 1 and Fig. 4, intra vane 3
Identical with the quantity of the first outer leafs 21 and be three.Certainly, intra vane 3 and the quantity of the first outer leafs 21 can also be without phase
With, for example in 5 example, the quantity of intra vane 3 is five, and the quantity of the first outer leafs 21 is three.Thus, by adjusting
The quantity of the first outer leafs 21 of section intra vane 3, such that it is able to improve the air output of axial-flow windwheel 100 entirety, reduces axle stream wind
The power of wheel 100 and noise.Here, it should be noted that the quantity of intra vane 3 is not limited to the quantity of the first outer leafs 21
State citing.
Alternatively, with reference to Fig. 1, when intra vane 3 is identical with the quantity of the first outer leafs 21, intra vane 3 and the first siphonal lobe
Piece 21 corresponds in the circumferential direction of outer wheel hub 11.That is, multiple first outer leafs 21 are in the periphery of outer wheel hub 11
Installation site on the internal perisporium of outer wheel hub 11 of installation site on wall and multiple intra vanes 3, in the circumference side of outer wheel hub 11
Inside and outside one-to-one corresponding upwards.
Or alternatively, with reference to Fig. 4, when intra vane 3 is identical with the quantity of the first outer leafs 21, intra vane 3 and first
Outer leafs 21 offset one from another in the circumference of described outer wheel hub 11.That is, multiple first outer leafs 21 are in outer wheel hub 11
Installation site on the internal perisporium of outer wheel hub 11 of installation site on periphery wall and multiple intra vanes 3, outer wheel hub 11 week
Inside and outside on direction do not correspond to.
For example in the example of fig. 4, multiple intra vanes 3 and multiple first outer leafs 21 are respectively about the center of outer wheel hub 11
Axis is centrosymmetric, but the company at each the first outer leafs 21 installation site on outer wheel hub 11 and outer wheel hub 11 center
Line and that intra vane 3 (i.e. with it on outer wheel hub 11 circumference closest that intra vane 3) closest with it exist
Between the line at the installation site on outer wheel hub 11 and outer wheel hub 11 center, there is certain angle α.So, when intra vane 3 and
One outer leafs 21 stagger certain angle when, intra vane 3 and the first outer leafs 21 circumgyration incision air and the periodic pressure that causes
The waveform of microseismic noise (i.e. the rotational noise of axial-flow windwheel 100) is essentially identical but phase place is different, contributes to reducing further axle
The Pneumatic rotary noise of stream wind wheel 100.
In addition, when the positive integer times of the quantity that the quantity of intra vane 3 is the first outer leafs 21, part intra vane 3 is permissible
Correspond in the circumference of outer wheel hub 11 with the first outer leafs 21.For example, when multiple intra vanes 3 and multiple first outer leafs 21
When being centrosymmetric respectively about the central axis of outer wheel hub 11, each first outer leafs 21 has one with it along foreign steamer
Hub 11 radial direction intra vane 3 relative to each other in inward-outward direction.
Preferably, an intra vane 3 constitutes the complete blade of an aerodynamic configuration with first outer leafs 21.Reference picture
1, an intra vane 3 comes from the complete small hub of same aerodynamic configuration than propeller type axle stream leaf with first outer leafs 21
Piece 2000, and intra vane 3 is the blade root that the complete small hub of aerodynamic configuration is than propeller type axial blade 2000, first
Outer leafs 21 are the blade tip portion that the complete small hub of this aerodynamic configuration is than propeller type axial blade 2000.Thus, by adopting
Small hub than axial blade blade tip portion as intra vane 3, enough such that it is able to provide under relatively low motor speed
Air circulation flow.
