Abstract
The present invention relates to a method for causing wind which is generated by an electric fan to be similar to natural wind, and an electric fan of natural wind. When people use an electric fan, people frequently feel uncomfortableness; because the wind which is generated by the electric fan has high a centripetal rotational angular velocity, people can generate symptoms, such as headaches, weakness, etc., when the electric fan is used for a long time. Thus, the present invention provides a method for eliminating or reducing a whirlwind (or vortex) phenomenon which is generated when a traditional electric fan operates by using combined blades, and provides the electric fan of natural wind with combined blades; the present invention causes the wind which is generated by the electric fan of natural wind to be more close to the motion state of natural wind, and then, the comfort and the safety of temperature drop of the people by using the electric fan are improved.
Description
The present invention relates to the electric fan of natural wind that a kind of wind that electric fan is formed is similar to 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, yet 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 is 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, so can not be had by the somebody of institute.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 are 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 people's that whirlwind brings health hazard also is big.In view of above situation, need a kind of method of invention and propose technological scheme corresponding with it, electric fan is produced be similar to natural wind.
The purpose of this invention is to provide the electric fan that a kind of wind that electric fan is formed is similar to natural wind, eliminate or reduce whirlwind (or eddy current) phenomenon of conventional fan generation when work, make the formed wind of electric fan more approach the motion state of natural wind, thereby improve travelling comfort, the Security that people use the electric fan cooling.
The object of the present invention is achieved like this:
A kind of electric fan of natural wind is made up of motor, combination fan blade and control system, it is characterized in that: a little fan blade is arranged a big fan blade the inside in the described combination fan blade.
The combination fan blade is when being the wind-force kind of drive, and initiatively the blade of fan blade is having envelope profile to driven fan blade with the mutually close zone of driven fan blade.
The driven blade shaft architecture of described combination fan blade is divided into bearing fixing three kinds of forms on the endoporus of an end, two ends and the blade shaft of guard.
Positive beneficial effect of the present invention:
The traditional electrical fan has a fan blade, formation be the whirlwind of a no external interference.Electric fan of natural wind is with making up fan blade, because a plurality of fan blades are arranged, each fan blade forms a whirlwind when rotated respectively.These whirlwind are in when contact, because the moving direction difference of local air molecule, each whirlwind just can interfere in the motion of circumferencial direction separately.The intensity of this interference can become with the angular velocity of the different whirlwind of several circumferential movement states in regional area and aggravate greatly.Because the existence of countless like this regional areas makes the circumferential movement of each whirlwind have mutual disturbance.After the rotatablely moving of some whirlwind of electric fan of natural wind combination fan blade takes place to pin down mutually to each other, just reduced the angular velocity of rotation of each whirlwind.The wind that the combination fan blade forms, the proal trend of wind can not weaken to each other.Institute's preface to sum up, use the combination fan blade to eliminate or reduce whirlwind (or eddy current) phenomenon of traditional electrical fan generation when work, it is a kind of effective measure, can make the wind of electric fan of natural wind institute shape more approach the motion state of natural wind, the travelling comfort, the Security that improve people's electricity consumption fan for cooling.
