Thus, the present invention provides a method for eliminating or reducing the whirlwind (or vortex) phenomenon which is generated when a traditional electric fan works by using a plurality of vanes, and designs the electric fan of natural wind with a plurality of vanes. The present invention causes the wind which is generated by the electric fan of natural wind to be close to the motion state of the natural wind, and then the comfort and the safety of the temperature drop of people by using the electric fan are improved.
Description
The present invention relates to a kind of electric fan of natural wind.
Electric fan is the essential electrical equipment of modern house, also is the main path that China resident was rely and self lowered the temperature and avoid heat in scorching summer.We usually use electric fan, however when using it, we often have such sensation-when the wind of electric fan on one's body, let us has been experienced nice and cool, also let us has been experienced a kind of feel embarrassed to mention uncomfortable.The uncomfortable sensation that produces during this use electric fan because of may causing ill symptomses such as " pyretic colds ", and has reduced the helpfulness of electric fan when reality is lowered the temperature thus.Air-conditioning temperature-reducing also has its negative effect, because indoor air is stale, indoor/outdoor temperature-difference is big, causes the human immunologic function easily and descends human body illness such as functional disturbance.Adopt air-conditioning temperature-reducing, the added value during the not only price height of air-conditioning, and use own is also high, and the use of air-conditioning simultaneously also is subjected to the restriction of room condition, does not have so be not preferably common people.For this reason, most of people express electric fan to hope, wish that it, can be safer, more comfortable when generation is nice and cool.
When people use electric fan, usually feel under the weather, the time has been grown, can make the people feel the headache, weak, sometimes also with sore-throat, arthralgia and symptoms such as functional disturbances of gastrointestinal tract in various degree.This mainly is because wind that electric fan produced and the natural cool breeze that we are sayed, due to both motion state differences.The motion state that both are different is again to be determined by the various environmental factors differences that form them.The wind that electric fan is produced by the fan blade high speed rotating, the proal while also with inevitably entad rotatablely moving, be wind be revolving proal, often tens times or hundred times are in the proal space rate of wind for its angular velocity that rotatablely moves, and we claim that usually this wind is whirlwind (or eddy current).The rotation direction of whirlwind that electric fan produces is identical with the fan blade rotation direction.We is out of doors the time in summer, and the natural cool breeze of being experienced belongs to the large size (for the wind that electric fan produced) that gas produces owing to the temperature difference and moves, and in this moving process, does not have the existence of obvious whirlwind phenomenon.As from the foregoing, when the whirlwind with high angular velocity of rotation and natural wind blow to our body surface respectively, difference to some extent in impression.This species diversity is the wind that the traditional electrical fan forms, and causes people to suffer from the reason of above-mentioned many pathological symptoms.These, be not found by people, understanding also gives profound understanding, because when making the three pieces type fan blade of traditional electrical fan, people consider that normally the area of each blade will try one's best greatly, the inclination angle is also big as far as possible, because air quantity and wind speed that such blade produces are big, and that the air flows of so big air quantity and wind speed can produce in people's customary sense of is directly proportional with it, cooling-down effect fast, do not recognize completely such blade also can form one same big, whirlwind with high angular velocity, big whirlwind also be big with health hazard with people.In view of above situation, need a kind of method of invention and propose technological scheme corresponding with it, make wind that electric fan produces be similar to natural wind.
The objective of the invention is to disclose a kind of method of the approximate natural wind of the formed wind of electric fan and electric fan of natural wind made from the method feature.
The present invention is a kind of method that makes the approximate natural wind of the formed wind of electric fan, it is characterized in that using Multiblade vane to eliminate or reduce whirlwind (or eddy current) phenomenon of traditional electrical fan generation when work, make the formed wind of electric fan more approach the motion state of natural wind, thereby improve the travelling comfort of people's electricity consumption fan for cooling.
For realizing the method for above-mentioned formation natural wind, the present invention proposes a kind of electric fan of natural wind of being made up of motor, Multiblade vane and control system etc., it is characterized in that Multiblade vane have five to tens, hundreds of sheet blade.

Figure 10 is traditional large size leaf area division figure.
Below in conjunction with accompanying drawing, describe disclosed method and electric fan of natural wind working principle in detail with Multiblade vane.
Electric fan of natural wind is made up of motor, Multiblade vane and control system etc.Multiblade vane is a kind of of fan blade.
The fan blade of traditional electrical fan adopts three pieces type, and the blade quantity of fan blade is the to the utmost for rare of four or five, and electric fan of natural wind is five to tens with the blade quantity of Multiblade vane, as Fig. 1～shown in Figure 9.When the blade of fan blade was three, the area of each blade was big with respect to the Multiblade vane blade area with tens blades.Is large-area blade man-made division A, B, four zones of C, D, as shown in figure 10.Large-area blade is when high speed rotating, and the air molecule in contact blade four zones air one by one is made up of the gas molecule of numerous species (or atom etc.), can be subjected to violent bump simultaneously, after they are stressed, and also while setting in motion.The motion air molecule that blade D district the excites blade of at first overflowing rotates forward.The air molecule in blade C district owing to also be lower than the blade rotational speed in its movement velocity of stressed back, can't be overflowed, in the proal while, continuous and impacted by the blade in D district, excited acceleration once more, could overflow then, its effusion speed is greater than D district air molecule effusion speed.According to this reason, blade B district air molecule is overflowed after C, D district quicken, and is that A district air molecule is overflowed after B, C, D district repeatedly quicken at last, so the angular velocity that A district air molecule rotates is the highest.The air molecule that excites with rear blade repeats the motion of A district air molecule continuously.As known from the above, factors such as the blade area size of fan blade have determined the angular velocity size that is rotated by the wind that fan blade forms.Electric fan of natural wind is many with the blade quantity of Multiblade vane, and blade area is comparatively speaking little, and the angular velocity that the air molecule that excites rotates is little.Like this, Multiblade vane is when producing moving air, and it is not obvious that the whirlwind phenomenon just becomes.Because the blade quantity of Multiblade vane is many, the air quantity of stirring forward simultaneously is big, so the wind that forms is in a kind of state of pushing ahead layer by layer near horizontal moving type, thus the wind that Multiblade vane produces not only soft and do not have the traditional electrical fan the sort of a burst of extremely strong extremely hard frequent variations of not having again for a moment of wind make us uncomfortable feeling.In sum, using the electric fan of natural wind Multiblade vane to eliminate or reduce whirlwind (or eddy current) phenomenon of traditional electrical fan generation when work, is a kind of method very reliably.
Fig. 1～Fig. 8 is an electric fan of natural wind Multiblade vane structural drawing, and Fig. 9 is the sectional drawing after the blade A-A in Fig. 1～Fig. 8 Multiblade vane structural drawing amplifies.The feature of Multiblade vane is that blade quantity is many, be five to tens, the hundreds of sheet.Electric fan of natural wind because blade view shape resembles big stick-means of intimidation, is excellent type so it is characterized in that blade with Multiblade vane A type structural drawing as shown in Figure 1.Multiblade vane Type B structural drawing because blade view shape resembles reaping hook, is a sickle so it is characterized in that blade as shown in Figure 2.Multiblade vane C type structural drawing as shown in Figure 3, blade view shape resembles letter " V ", is " V " type so it is characterized in that blade.Multiblade vane D type structural drawing because blade view shape resembles snakelike or serpentine, is snake type (or serpentine) so it is characterized in that blade as shown in Figure 4.Multiblade vane E type structural drawing because blade view shape resembles bent moon, is a curved month type so it is characterized in that blade as shown in Figure 5.The Multiblade vane structural drawing of Fig. 6～Fig. 8 is characterized in that having the setting of some ring-type stiffening rings on the basis of Fig. 1～Fig. 5 Multiblade vane structural drawing.Blade is oblique in Fig. 9 sectional drawing, shows that blade has certain angle of inclination, and certainly, this true dip direction and angle change with the rotation direction of electric fan of natural wind Multiblade vane and the conditions such as diverse location of blade.
The electric fan of natural wind Multiblade vane has multi-disc small size blade, and the motion air quantity that every blade is stirred is little, and air is difficult for forming higher angle of rotation motion.The little air motion that these monolithic small size blades form is done simultaneously by many blades, and the moving air amount of generation can be than not the lacking of large size fan blade, by comparison, and but at double minimizing of the former whirlwind (or eddy current).Electric fan of natural wind has not only improved people and has used the validity of its heat with temperature, and increased comfortable and safety owing to effectively reduced the formation of whirlwind.
