Wherein 1 is wheel hub, and 2 is wheel disc, and 3 is leaf blade, and 4 is fan blade outer ring.
Embodiment
Further understanding to do the present invention, coordinating accompanying drawing to be further described below:
As shown in Figure 1-2, invention demonstrates a method a kind of Xi Luoke fan blade, comprise wheel disc 2, be provided with the wheel hub 1 to side indent in the intermediate portion of wheel disc, the concave inward structure of this wheel hub is used for mounted motor.On wheel disc with in the outward edge circumference of this phase the same side, wheel hub indent direction, be connected with several leaf blades of evenly arranging, this leaf blade head end side is connected on wheel disc, and the side that leaf blade end is relative is connected with fan blade outer ring.Wheel disc entirety is round structure, and this fan blade outer ring entirety is in circular shape structure, and fan blade outer ring is linked together by leaf blade and wheel disc.
Leaf blade is equal to the distance in the wheel disc center of circle away from the one end in the wheel disc center of circle, and this distance is R1, and one end that leaf blade is connected on wheel disc is also equal to the distance in the described wheel disc center of circle, and this distance is R2.Leaf blade is the arc shaped blade with certain crooked radian, so there is certain angle in the position that leaf blade is connected with fan blade outer ring, in the present invention, be α with the acute angle of described fan blade outer ring tangent line inside the blade of leaf blade outlet port, leaf blade number is Z, and above parameter meets following relation:
.
As preferred scheme, leaf blade quantity
(wherein Z round number), can by the size of R1/R2, and the size of α determines the quantity of Z in conjunction with this parameters relationship.
As another one preferred version, leaf blade number
(wherein Z round number), can by the size of R1/R2, and the size of α determines the quantity of Z in conjunction with this parameters relationship.
As the 3rd preferred version, leaf blade number
(wherein Z round number).Can by the size of R1/R2, and the size of α determines the quantity of Z in conjunction with this parameters relationship.
In the utility model, in conjunction with the actual use size of wall-hanging air conditioner, the angle of the acute angle α of inside the blade of leaf blade outlet port and described fan blade outer ring tangent line is between 60 ° to 80 °, leaf blade away from the one end in the wheel disc center of circle to the length of the distance R1 in the wheel disc center of circle between 260mm to 350mm, leaf blade is connected to the length of the one end on wheel disc to the distance R2 in the wheel disc center of circle at 150mm to 220mm.
In conjunction with the number range of R1/R2 and the number range of α, and Parameter relation formula above, can the very fast number range Z deriving leaf blade number be 13-19 sheet.In conjunction with testing authentication, can show that air blade number is when 13 and 15, the pneumatic travelling comfort of fan blade is best.
According to specifically verifying situation, draw following list data:
Table 1: different exit angle α and R2 test data table:
Table 2: fan blade performance test data table under different number:
Experimentally data are when Z gets 13 or 15, the air quantity of fan blade and power best results.
Xi Luoke fan blade air blade number in the utility model is selected rationally, when ensureing that number of blade quantity is few, frictional loss rate, air port resistance are little, also make the expansion blade of fan blade little as far as possible, make the separation rate of flow boundary layer air can not be too high, good, the pneumatic travelling comfort of air-out effect of this fan blade be strong.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection domain that the utility model requires is defined by appending claims and equivalent thereof.
