As shown in Figure 1, according to the utility model first aspect embodiment's axial-flow windwheel 100, comprising: outer wheel hub 11, inner wheel hub 12, multiple outer leafs and multiple intra vane 3.Here, it should be noted that, " interior " can be understood as the direction towards axial-flow windwheel 100 rotating centers, and its opposite direction is defined as " outward ", away from the direction of axial-flow windwheel 100 rotating centers.
With reference to Fig. 1, inner wheel hub 12 is located in outer wheel hub 11, multiple outer leafs are located on the periphery wall of outer wheel hub 11, and multiple outer leafs are circumferentially arranged spaced apart along outer wheel hub 11, multiple intra vanes 3 are located between inner wheel hub 12 and the inner circle wall of outer wheel hub 11, and circumferentially arranged spaced apart along inner wheel hub 12 of multiple intra vane 3.Alternatively, the central axes of inner wheel hub 12 and outer wheel hub 11, thus the wind wheel being made up of with inner wheel hub 12 intra vane 3 is identical with the rotating center of the wind wheel being made up of outer leafs and outer wheel hub 11, makes the air-supply of axial-flow windwheel 100 more concentrated.
Particularly, as shown in Figure 1, inner wheel hub 12 is roughly one end and opens wide, the cylindrical shape of the other end sealing, outer wheel hub 11 is roughly the cylindrical shape of both ends open, inner wheel hub 12 is contained in outer wheel hub 11, multiple outer leafs are from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11, the inner end edge of multiple intra vanes 3 is connected with the periphery wall of inner wheel hub 12 and the inner circle wall face of outer wheel hub 11 respectively with outer end edges, that is to say, the periphery wall that extend radially outwardly to outer wheel hub 11 of multiple intra vanes 3 from the periphery wall of inner wheel hub 12 along inner wheel hub 12, outer wheel hub 11 is connected with inner wheel hub 12 by multiple intra vanes 3.
Thus, inner wheel hub 12 directly adopts intra vane 3 to be connected with outer wheel hub 11, axial-flow windwheel 100 structure complexities are reduced, be convenient to processing and assembling, and improve the intensity of axial-flow windwheel 100, also avoided in addition adopting other linkage structures may be on the impact in the flow field of axial-flow windwheel 100, ensured that axial-flow windwheel 100 has excellent aeroperformance.In addition, the compact structure of axial-flow windwheel 100, good integrity, shared structure space is less, thereby makes axial-flow windwheel 100 be specially adapted to have to air supplying distance with to shared structure space the occasion explicitly calling for, for example, be applicable to air conditioner outdoor machine 1001 or indoor apparatus of air conditioner 1002 etc.
Certainly, the utility model is not limited to this, intra vane 3 can also only be connected with the periphery wall of inner wheel hub 12, and be not connected with the inner circle wall face of outer wheel hub 11, that is to say, multiple intra vanes 3 are from periphery wall the extending radially outwardly and the outer end edges of intra vane 3 and the inner circle wall face of outer wheel hub 11 maintenance certain interval (scheming not shown) along inner wheel hub 12 of inner wheel hub 12.
Further, with reference to Fig. 1, multiple outer leafs can be evenly distributed on the periphery wall of outer wheel hub 11, that is to say, angle between two outer leafs of arbitrary neighborhood can equate, and multiple intra vanes 3 can be evenly distributed on the periphery wall of inner wheel hub 12, that is to say, the angle between two intra vanes 3 of arbitrary neighborhood can equate.
Certainly, the utility model is not limited to this, multiple outer leafs can also anisotropically be distributed on the periphery wall of outer wheel hub 11 (scheming not shown), that is to say, angle between two outer leafs of arbitrary neighborhood can be unequal, and multiple intra vanes 3 also can be distributed on the periphery wall of inner wheel hub 12 unevenly, that is to say, the angle between two intra vanes 3 of arbitrary neighborhood can be unequal.
Like this, due to inside and outside intra vane 3 and the outer leafs distributing can be set on axial-flow windwheel 100 simultaneously, thereby intra vane 3 and outer leafs can be arranged to respectively to different types, to improve the air-supply effect of axial-flow windwheel 100.

Further, with reference to Fig. 2 and Fig. 3, along the axial direction of axial-flow windwheel 100, the plane of rotation of intra vane 3 and outer leafs can be similar in same plane, thereby intra vane 3 can carry out in same plane inter-sync with air intake and the air-out of outer leafs, there is not the air-flow interference problem causing due to intra vane 3 and the range difference of outer leafs in the axial direction of axial-flow windwheel 100, thereby do not exist due to the intra vane 3 off-design operating mode work impact that externally blade working produces, there is not the impact that may produce intra vane 3 work due to the work of outer leafs off-design operating mode yet, and then improve the stability of the aeroperformance of axial-flow windwheel 100, and in the time of axial-flow windwheel 100 off-design operating mode, still can obtain good air-supply effect, make axial-flow windwheel 100 more be beneficial to applying in Practical Project.In addition, reduce design difficulty, reduced cost of production.
According to the utility model embodiment's axial-flow windwheel 100, by intra vane 3 and outer leafs are set on axial-flow windwheel 100 simultaneously, thereby can carry out effective cutting to the air-out air trajectory of axial-flow windwheel 100 entirety, thereby effectively improve the air-out effect of axial-flow windwheel 100, made axial-flow windwheel 100 can take into account air supplying distance and air-supply power.
In an embodiment of the present utility model, multiple outer leafs comprise multiple the first outer leafs 21 and multiple the second outer leafs 22.With reference to Fig. 1, multiple the first outer leafs 21 are from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11, and the shape of multiple the first outer leafs 21, size are all identical, established angle on outer wheel hub 11 is also identical, preferably, in the time that multiple the first outer leafs 21 are evenly distributed on outer wheel hub 11, multiple the first outer leafs 21 can be obtained by first outer leafs 21 axle, annular array centered by the central axis of outer wheel hub 11, and now multiple the first outer leafs 21 distribute with respect to the central axis of coaxial inner wheel hub 12 and outer wheel hub 11 with being centrosymmetric.
With reference to Fig. 1, multiple the second outer leafs 22 are from periphery wall the extending radially outwardly along outer wheel hub 11 of outer wheel hub 11, and the shape of multiple the second outer leafs 22, size are all identical, established angle on outer wheel hub 11 is also identical, preferably, in the time that multiple the second outer leafs 22 are evenly distributed on outer wheel hub 11, multiple the second outer leafs 22 can be obtained by second outer leafs 22 axle, annular array centered by the central axis of outer wheel hub 11, and now multiple the second outer leafs 22 distribute with respect to the central axis of coaxial inner wheel hub 12 and outer wheel hub 11 with being centrosymmetric.
Here it should be noted that, as shown in Figure 1, the rotor diameter that multiple the first outer leafs 21 and outer wheel hub 11 form can equal the rotor diameter that multiple the second outer leafs 22 and outer wheel hub 11 form, that is to say, the radial length of the first outer leafs 21 equates with the radial length of the second outer leafs 22.Certainly, multiple the first outer leafs 21 can also be unequal with the rotor diameter that outer wheel hub 11 forms with rotor diameter and multiple the second outer leafs 22 that outer wheel hub 11 forms, and the radial length of the radial length of the first outer leafs 21 and the second outer leafs 22 is unequal.
Preferably, the blade shape of the blade shape of the first outer leafs 21 and the second outer leafs 22 differs from one another.For example, the first outer leafs 21 is different from the type of the second outer leafs 22, or the first outer leafs 21 is identical with the type of the second outer leafs 22, and the first outer leafs 21 is different from the aerodynamic configuration of the second outer leafs 22.Here, it should be noted that, according to the technical term of wind wheel design, " type of blade is identical " can be understood as the value of " specific speed " of blade place wind wheel roughly in identical numerical value interval, such as all in 100 magnitudes, 200 magnitudes etc., and " the aerodynamic configuration difference " of blade can be understood as the value of " specific speed " of blade place wind wheel roughly in identical numerical value interval, but because the difference of blade structure details, and make the concrete value difference of " specific speed " of wind wheel.
In the time that the vane type of the first outer leafs 21 and the second outer leafs 22 is different, preferably, with reference to Fig. 1, the first outer leafs 21 is that the conventional small hub that lacks blade is than propeller type axial blade 2000, the second outer leafs 22 is that multiple-blade big hub is than axial blade 3000, wherein, with reference to Fig. 9, " small hub is than propeller type axial blade " refers to the blade of the axial-flow windwheel with small hub ratio, wherein small hub is than referring to the smaller of the hub diameter of wind wheel and wind wheel integral diameter, ratio range is generally and is less than or equal to 0.2, such axial-flow windwheel generally has less blade, and can under relatively low motor speed, provide enough air circulation flows when the blade working of such axial-flow windwheel, with reference to Figure 10, " big hub is than axial blade " refers to the blade of the axial-flow windwheel with big hub ratio, wherein big hub is than referring to the larger of the hub diameter of wind wheel and wind wheel integral diameter, ratio range is generally and is more than or equal to 0.4, such axial-flow windwheel generally has more blade, and the blade of such axial-flow windwheel can improve the total head of delivery air under relatively low motor speed.
When the first outer leafs 21 identical with the type of the second outer leafs 22, when but the aerodynamic configuration of the first outer leafs 21 and the second outer leafs 22 is different, alternatively, the first outer leafs 21 and the second outer leafs 22 are conventional small hub than propeller type axial blade 2000, or be conventional small hub than the blade tip portion of propeller type axial blade 2000 (will describe in detail hereinafter), 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, kind, aerodynamic configuration and the constituted mode of the first outer leafs 21 and the second outer leafs 22 are all not limited to mentioned above.
As shown in Figure 1-Figure 3, when the first outer leafs 21 is that conventional small hub is than propeller type axial blade 2000, and the second outer leafs 22 is big hub during than axial blade 3000, and the first outer leafs 21 can be that conventional small hub is than the blade tip portion of propeller type axial blade 2000.When concrete structure, small hub can be from periphery wall the extending radially outwardly along inner wheel hub 12 of inner wheel hub 12 than propeller type axial blade 2000, and extend to the outside of outer wheel hub 11, small hub is considered as to small hub than the blade root of propeller type axial blade 2000 than the part between outer wheel hub 11 and inner wheel hub 12 of propeller type axial blade 2000, small hub is considered as to small hub than the blade tip portion of propeller type axial blade 2000 than the part that is positioned at outer wheel hub 11 outsides of propeller type axial blade 2000, give up small hub than the blade root of propeller type axial blade 2000, and retain small hub than the blade tip portion of propeller type axial blade 2000 as the first outer leafs 21, thereby can under relatively low motor speed, provide enough air circulation flows.
But, the second outer leafs 22 can be that big hub is than the entirety of axial blade 3000, when concrete structure, with reference to Fig. 1, big hub can extending radially outwardly from the periphery wall of outer wheel hub 11 along outer wheel hub 11 than axial blade 3000, like this big hub is considered as to the second outer leafs 22 than the entirety of axial blade 3000.
Thus, when the first outer leafs 21 is that conventional small hub is than the blade tip portion of propeller type axial blade 2000, and when the second outer leafs 22 is big hub than axial blade 3000 overall, when the radial length of the first outer leafs 21 and the second outer leafs 22 can be identical, that is to say, the rotor diameter of the wind wheel that the first outer leafs 21 and outer wheel hub 11 form can be identical with the rotor diameter of the wind wheel that the second outer leafs 22 and outer wheel hub 11 form.Thus, by adopt big hub than axial blade 3000 as the second outer leafs 22, and the second outer leafs 22 is arranged on the periphery wall of the outer wheel hub 11 that peripheral velocity is the highest, thereby under relatively low motor speed, can improve the total head of delivery air, and can not cause that air-supply noise increases, also can not cause frictional loss increase, the increase of output power of air-flow, and then can reduce air-supply noise and the power of axial-flow windwheel 100.
Further, with reference to Fig. 1, the first outer leafs 21 and the second outer leafs 22 are circumferentially alternately arranged along outer wheel hub 11.Specifically alternatively, between two the first outer leafs 21 of arbitrary neighborhood, be provided with at least one second outer leafs 22, and the quantity of the second outer leafs 22 between every two adjacent the first outer leafs 21 can be different.
Alternatively, the quantity of the second outer leafs 22 be the first outer leafs 21 quantity N doubly, wherein N is more than or equal to 1 positive integer.That is to say, the quantity of the second outer leafs 22 equates with the quantity of the first outer leafs 21, or the quantity of the second outer leafs 22 is positive integers times of the quantity of the first outer leafs 21, now, when the first outer leafs 21 and the second outer leafs 22 are during along circumferentially alternately the arranging equably of outer wheel hub 11, the quantity of the second outer leafs 22 being provided with between two the first outer leafs 21 of arbitrary neighborhood is identical, further, when the shape of multiple the first outer leafs 21 all identical, and the shape homogeneous phase of multiple the second outer leafs 22 simultaneously, outer leafs entirety is centrosymmetric about the central axis of outer wheel hub 11.
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, between every two adjacent the first outer leafs 21, be provided with two the second outer leafs 22, now the quantity of the second outer leafs 22 is two times of quantity of the first outer leafs 21, in the time that three the first outer leafs 21 and six the second outer leafs 22 are centrosymmetric about the central axis of outer wheel hub 11 respectively, outer leafs entirety is centrosymmetric about the central axis of outer wheel hub 11, thereby has improved the run stability of wind wheel.
Certainly, the utility model is not limited to this, the first outer leafs 21 and the second outer leafs 22 can also alternately not arranged along the circumferential of outer wheel hub 11, that is to say, between two the first outer leafs 21 of arbitrary neighborhood, can not be provided with the second outer leafs 22 or be provided with at least one second outer leafs 22.
Thus, by on the periphery wall at outer wheel hub 11, arrange small hub than propeller type axial blade 2000 and big hub than the blade of 3,000 two types of axial blades, and two kinds of blades are along the circumferential alternative arrangement of outer wheel hub 11, due to slight hub ratio propeller type axial blade 2000, than the rotating center of axial blade 3000, velocity vector identical but exit flow separately is not identical with big hub, thereby along air throughput direction, the air-flow of two kinds of vane drive can cross and jointly discharge forward at axial-flow windwheel 100 downstream parts, the directionality of air-flow of making to cross is better, avoid the Divergent Phenomenon of air-flow, effectively increase air supplying distance.
In an embodiment of the present utility model, with reference to Fig. 1, multiple intra vanes 3 are connected between outer wheel hub 11 and inner wheel hub 12, and the shape of multiple intra vanes 3, size are all identical, established angle on inner wheel hub 12 is also identical, preferably, in the time that multiple intra vanes 3 are evenly distributed on inner wheel hub 12, multiple intra vanes 3 can be obtained by an intra vane 3 axle, annular array centered by the central axis of inner wheel hub 12, and now multiple intra vanes 3 distribute with respect to the central axis of coaxial inner wheel hub 12 and outer wheel hub 11 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, the quantity of intra vane 3 and the first outer leafs 21 is identical and be three.Certainly, intra vane 3 can also be not identical with the quantity of the first outer leafs 21, and 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 regulating the quantity of the first outer leafs 21 of intra vane 3, thereby can improve the air output of axial-flow windwheel 100 entirety, reduce power and the noise of axial-flow windwheel 100.Here, it should be noted that, the quantity of the quantity of intra vane 3 and the first outer leafs 21 is not limited to above-mentioned giving an example.
Alternatively, with reference to Fig. 1, in the time that the quantity of intra vane 3 and the first outer leafs 21 is identical, intra vane 3 is corresponding one by one in the circumferential direction of outer wheel hub 11 with the first outer leafs 21.That is to say, multiple the first mounting points of outer leafs 21 on the periphery wall of outer wheel hub 11 are the mounting point on the inner circle wall of outer wheel hub 11, corresponding one by one inside and outside in the circumferential direction of outer wheel hub 11 with multiple intra vanes 3.
Or alternatively,, with reference to Fig. 4, in the time that the quantity of intra vane 3 and the first outer leafs 21 is identical, intra vane 3 and the first outer leafs 21 upwards staggered each other in the week of described outer wheel hub 11.That is to say, multiple the first mounting points of outer leafs 21 on the periphery wall of outer wheel hub 11 are the mounting point on the inner circle wall of outer wheel hub 11, not corresponding inside and outside in the circumferential direction of outer wheel hub 11 with multiple intra vanes 3.
For example, in the example of Fig. 4, multiple intra vanes 3 are centrosymmetric about the central axis of outer wheel hub 11 respectively with multiple the first outer leafs 21, but the line at the mounting point of each the first outer leafs 21 on outer wheel hub 11 and outer wheel hub 11 centers and and the mounting point of its that nearest intra vane 3 (and its at upwards nearest that intra vane 3 of outer wheel hub 11 weeks) on outer wheel hub 11 and the line at outer wheel hub 11 centers between there is certain angle α.Like this, in the time that intra vane 3 and the first outer leafs 21 stagger several angle, the waveform of the periodic pressure microseismic noise (being the rotational noise of axial-flow windwheel 100) that intra vane 3 causes from the first outer leafs 21 circumgyration incision air is basic identical but phase place is different, contributes to further to reduce the Pneumatic rotary noise of axial-flow windwheel 100.
In addition, in the time that the quantity of intra vane 3 is the positive integer times of quantity of the first outer leafs 21, part intra vane 3 can be upwards corresponding one by one in the week of outer wheel hub 11 with the first outer leafs 21.For example, in the time that multiple intra vanes 3 and multiple the first outer leafs 21 are centrosymmetric about the central axis of outer wheel hub 11 respectively, each the first outer leafs 21 have one with it along radially intra vane 3 respect to one another in inward-outward direction of outer wheel hub 11.
Preferably, an intra vane 3 and first outer leafs 21 form a blade that aerodynamic configuration is complete.With reference to Fig. 1, intra vane 3 and first outer leafs 21 come from small hub that same aerodynamic configuration is complete than propeller type axial blade 2000, and intra vane 3 be small hub that aerodynamic configuration is complete than the blade root of propeller type axial blade 2000, the first outer leafs 21 is that small hub that this aerodynamic configuration is complete is than the blade tip portion of propeller type axial blade 2000.Thus, by adopt small hub than the blade tip portion of axial blade as intra vane 3, thereby enough air circulation flows can be provided under relatively low motor speed.
