Speed, unit are rev/min (rpm)；D is the blade tip diameter of fan 12, and unit is millimeter (mm).Wherein, 90 ° of 67 °≤γ <, L >=
0.019m, n >=31000rpm, d≤82mm, when meeting above-mentioned condition, output wind energy of the fan 12 in unit flow area
Ability K be more than or equal to 480.
K is the ability of output wind energy of the fan 12 in unit flow area herein, obtains K about above four by experiment
Function K=f (γ, L, n, d) of a parameter.In other words, the ability K of output wind energy of the fan 12 in unit flow area with
Flabellum maximum established angle γ, flabellum maximum chord length L, rotation speed of the fan n are related to blade tip diameter d.As shown in Figure 5, Figure 6, flabellum string
The intersection length that a length of flabellum coaxially intersects with imaginary entity of the diameter between fan hub diameter and blade tip diameter, herein
Imaginary entity structure is identical as the structure of fan hub, is of different sizes, the diameter difference of imaginary entity with fan hub,
Also different with the intersection length that flabellum coaxially intersects, flabellum maximum chord length L is the maximum value of multiple intersection length, this implementation
Flabellum maximum chord length L is the intersection length of flabellum root and hub surface in example；Blade tip diameter d is the highest of the flabellum of fan 12
Locate the diameter of position.Flabellum root to form connecting line with connecting with hub surface, and flabellum established angle is the connecting line each point
This is perpendicular to sharp between the tangent line of central axis 101 on the tangent line and hub surface in the plane perpendicular to hub radius
Angle, flabellum maximum established angle γ are the maximum value of flabellum established angle；Rotation speed of the fan n is the rotation of the fan 12 driven by motor 13
Speed, in the present embodiment, motor 13 and fan 12 are co-axially mounted, and rotation speed of the fan n is substantially equal with the revolving speed of motor 13, specifically
The revolving speed of ground, motor 13 and fan 12 is all larger than equal to 31000 revs/min.It should be understood that in other embodiments of the present invention,
The revolving speed of rotation speed of the fan n and motor 13 can also be unequal.
Fig. 7 show fan 12 in the ability K of the output wind energy in unit flow area, hair dryer 100 at air outlet B
100 main screw lift G of output wind speed V and hair dryer between functional relation curve graph.In fact, main screw lift G be about
The function of blade tip diameter d, output wind speed V are about flabellum maximum established angle γ, flabellum maximum chord length L and rotation speed of the fan n tri-
The function of person.As shown in Figure 7, when the ability K of the output wind energy when the fan of design 12 in unit flow area is equal to 480,
Output wind speed V of the hair dryer 100 at air outlet B reaches 150MPH(mile perhour), while the complete machine weight of hair dryer 100
Amount is about 2.00 kg；When the ability K of output wind energy of the fan 12 in unit flow area is greater than 480, hair dryer 100 exists
Output wind speed V at air outlet B is greater than 150MPH, while 100 main screw lift G of hair dryer is less than 2.00 kg；Further, when
The ability K of output wind energy of the fan 12 in unit flow area is greater than 0 and when less than 480, and hair dryer 100 is at air outlet B
Output wind speed V be greater than 0 and be less than 150MPH, while 100 main screw lift G of hair dryer be greater than 2.00 kg；When fan 12 is in unit
When the ability K > 510 of the output wind energy in flow area, output wind speed V of the hair dryer 100 at air outlet B is greater than 170MPH,
100 main screw lift G of hair dryer is less than 1.85 kg simultaneously.Therefore, the output wind by control fan 12 in unit flow area
The ability K of energy, so that it may obtain corresponding main screw lift G and output wind speed V.It certainly, fundamentally will be improved by setting
The performance of the specific structure of fan 12 and motor 13 adjusts the ability K of output wind energy of the fan 12 in unit flow area
's.
To sum up, exist by adjusting the radial dimension of 11 different parts of air duct portion of this hair dryer 100 and control fan 12
The ability K of output wind energy in unit flow area makes hair dryer 100 have service performance more outstanding and more preferably
Structure design, specially has less energy loss, higher output wind speed V and more compact light complete machine structure.
