The limitation of novel protected range.
Fig. 1-Fig. 4 is please referred to, one aspect according to the present utility model provides a kind of electric fan, comprising: hub 2；It is more
A arc-shaped flabellum 1, flabellum 1 are connect along the root that the circumferential direction of hub 2 is successively spaced setting and flabellum 1 with the side of hub 2,
Wherein；Flabellum diameter 14 is 198~201mm, and each flabellum rotation interior angle A is 39~42 °, each flabellum rotation exterior angle B is 9~
12°。
Refering to fig. 1 with Fig. 4, in a preferred embodiment, flabellum diameter 11 is 200mm.It should be noted that as schemed
Shown in 1, flabellum diameter 11 refers to hub center to twice of distance of limb of flabellum, by increasing flabellum diameter 11, one
Aspect makes the increase air output of evaporating fan, on the other hand can improve the wind-out range of evaporating fan, so that air-out effect
More preferably.
Refering to fig. 1, Fig. 2 and Fig. 3, in a preferred embodiment, each flabellum rotation interior angle A is 41 °, each flabellum
Rotating exterior angle B is 10 °.Specifically, each flabellum 1 is inclined on the side of hub 1, and each flabellum 1 divides for interior outside
Two parts；As shown in Figures 1 and 2, on the basis of hub 2, the upper surface 21 of 13 whole tendency hubs 2 on the inside of flabellum, outside flabellum
12 entirety of side is inclined to the lower surface of hub 2, and flabellum rotation interior angle A and flabellum rotation exterior angle B are exactly in flabellum outside 12 and flabellum
The angle that side 13 is reversed for this datum plane of hub 2；As shown in Figure 1 and Figure 2, using hub 2 as initial plane,
The angle formed between 13 entirety and the upper surface 21 of hub 2 on the inside of flabellum is flabellum rotation interior angle A, that is to say, that on the inside of flabellum
The degree that 13 whole opposite hubs 2 are reversed to the upper surface of hub is 41 °；The 12 whole lower surface 23 with hub 2 on the outside of flabellum
Between the angle that is formed be flabellum rotation exterior angle B, that is to say, that the degree that the lower surface of 12 whole opposite hubs 2 is reversed on the outside of flabellum
Number is 10 °.As shown in Figures 1 and 3, by rotating the angle adjustment of interior angle 12, flabellum rotation exterior angle 11 to flabellum, so that evaporation
Fan intake and air output in rotation increase, and wind-out range is wider, and air inlet/outlet effect as shown in Figure 3 thus increases
Disengagement area in big evaporator, can satisfy the heat transfer requirements of evaporator, improves the heat transfer effect of evaporator.
Refering to fig. 1, it is preferable that circumferential spaced set of the flabellum 1 along hub 2.Setting purpose in this way is, in evaporating fan
During rotation, the centrifugal force for the fan rotation that hub 2 is born is close to zero, and is theoretically solely subjected to the gravity of evaporating fan,
There can be during rotation excessive vibration to avoid flabellum and the bearing of hub 2 is damaged, be able to extend entire evaporation
The service life of fan.
Refering to fig. 1, it is preferable that the quantity of flabellum 1 is 5.Specifically, 1 quantity of flabellum increases, can in effective axis
To height it is certain in the case where, increase the torsional angle of each flabellum 1, to achieve the purpose that increase into and out of air quantity and wind velocity out.
It should be noted that flabellum 1 may be set to be the odd numbers pieces such as 3,7, the purpose of the application may be implemented, herein no longer
It repeats, as long as objective is not detached from the design philosophy of the utility model, both is within the protection scope of the present invention.
Preferably, flabellum 1 is integrally formed with hub 2.Specifically, flabellum 1 and hub 2 using aluminium material and pass through mould
Have die casting to be integrally formed, on the one hand reinforces the structural strength of flabellum 1, be on the other hand integrally formed easy to produce, the production of raising
Efficiency no longer needs to carry out installation fixation, saves the set-up time there are also being exactly integrally formed flabellum 1 and hub 2.
Other side according to the present utility model also provides a kind of evaporating fan, including above-mentioned electric fan, and
One driving motor, hub 2 are mounted in the drive shaft of driving motor.The output with driving motor drive shaft is provided on hub 2
The connecting hole 22 being fixedly connected is held, it is that evaporator passes through wind-force that driving motor rotation, which drives the rotation of flabellum 1 of fan,.
It is straight to increase flabellum by adding the quantity of flabellum for a kind of electric fan and evaporating fan provided by the utility model
Diameter, so that the air output of fan entirety becomes larger, wind velocity lift；Exterior angle is rotated additionally by adjustment flabellum rotation interior angle and flabellum,
While increasing into and out of air quantity wind-out range is expanded, so that the disengagement area in steamer increases, improves and evaporate
The heat transfer effect of device.
It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality
