Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to the accompanying drawings axial-flow windwheel 1 according to the utility model embodiment is described.
As shown in Figure 1-Figure 3, wheel hub 100, multiple first blade 200 and multiple second blade 300 is comprised according to the axial-flow windwheel 1 of the utility model embodiment.
Multiple first blade 200 and multiple second blade 300 are crisscross arranged on wheel hub 100, multiple first blade 200 and multiple second blade 300 uniform intervals are arranged, the shape of the first blade 200 and the leaf identical of the second blade 300, and the size of the first blade 200 is less than the size of the second blade 300.
According to the axial-flow windwheel 1 of the utility model embodiment, by multiple first blade 200 and multiple second blade 300 are crisscross arranged on wheel hub 100, can when multiple first blade 200 and multiple second blade 300 rotate with wheel hub 100, first blade 200 and the second blade 300 are kept out the wind mutually when rotating, and be less than the size of the second blade 300 due to the size of the first blade 200, the resistance of air be subject to when axial-flow windwheel 1 rotates can be reduced on the one hand, thus reduce the noise that axial-flow windwheel 1 sends when rotating, axial-flow windwheel 1 can be made to blow on the other hand more even, prevent from producing different sound because local air flow is uneven, thus the tonequality improved when axial-flow windwheel 1 rotates.
And, because multiple first blade 200 is disposed in an evenly spaced relation on wheel hub 100 with the leaf identical of multiple second blade 300, the resistance of air be subject to when axial-flow windwheel 1 can be made to rotate is more even, thus improve the uniformity of axial-flow windwheel 1 air-supply further, improve tonequality when axial-flow windwheel 1 rotates further.
Therefore, according to the axial-flow windwheel 1 of the utility model embodiment have air-supply evenly, rotate time noise low, can the advantages such as tonequality be improved.
Below with reference to the accompanying drawings axial-flow windwheel 1 according to the utility model specific embodiment is described.
In specific embodiments more of the present utility model, as shown in Figure 1-Figure 3, wheel hub 100, multiple first blade 200 and multiple second blade 300 is comprised according to the axial-flow windwheel 1 of the utility model embodiment.
Particularly, as shown in Figure 2, for the second blade 300, each first blade 200 and the second blade 300 can include blade root 310, blade tip 320, leading edge 330, trailing edge 340.
Advantageously, as shown in Figure 3, the blade root 310 of multiple first blade 200 can be in the same plane with the joint of leading edge 330 with the blade root 310 of the joint of leading edge 330 and multiple second blade 300.Not only can ensure the mutual windproof effect of the first blade 200 and the second blade 300 thus, and the uniformity of axial-flow windwheel 1 air-supply can be improved further.
Alternatively, the ratio range of the size of the first blade 200 and the size of the second blade 300 can be 1:1 ~ 0.1:1.The resistance of air be subject to when axial-flow windwheel 1 rotates can be reduced thus when the windproof effect of guarantee first blade 200 to the second blade 300.
Fig. 1-Fig. 3 shows the axial-flow windwheel 1 according to the utility model concrete example.As depicted in figs. 1 and 2, in the axial direction, the part of the contiguous blade tip 210 of each first blade 200 can have projection on the second adjacent blade 300.The air-supply air quantity of axial-flow windwheel 1 can be improved thus, ensure the air-supply effect of axial-flow windwheel 1.
Particularly, as depicted in figs. 1 and 2, the cross section of the outer circumferential face of wheel hub 100 can be circular.Not only so that the installation of the first blade 200 and the second blade 300, the manufacture of wheel hub 100 can be convenient to, and the resistance of air be subject to when wheel hub 100 rotates can be reduced thus, when preventing wheel hub 100 from rotating, interference is produced to air-flow.
Alternatively, Fig. 1-Fig. 3 shows the embodiment that the first blade 200 and the second blade 300 are three.When the first blade 200 and the second blade 300 are three, angle (as shown in fig. ia) between the first adjacent blade 200 and the second blade 300 is equal and be 60 degree, angle (as shown in fig. ib) between adjacent two the first blades 200 is equal and be 120 degree, and the angle (as shown in the c in Fig. 1) between adjacent two the second blades is equal and be 120 degree.
