Background technique
Fan is a kind of by allowing air circulation and flow and take away the cooling device of heat, is a kind of indoor electric appliance of traditional, environmental protection.Fan is according to the mode type difference of air-out; can be divided into three kinds of forms; a kind of is by the axial flow fan of motor drives around the direct disturbance wind flow of a plurality of flabellums of rotational; this fan is traditional common electric fan form; comprise the isostructural fan of ceiling fan and desk fan; the flabellum of this fan is exposed to the outside more; hurt sb.'s feelings in order to prevent that flabellum from coming off; the object that perhaps prevents the outside touches flabellum; some protecting jackets or isolation mounting are set around flabellum usually; perhaps, be far from the crowd high the slinging of fan.Thisly directly come the fan of disturbance wind to adopt common Wechselstrommotor to drive usually by flabellum, and adopt large stretch of cutter shape flabellum, can produce huge noise like this, this fan is shown in Chinese patent application 200820002255.1.If protecting jacket is set in the flabellum outside, the noise that more is easy to generate, and hinder gas flow, reduced the flow effect of wind.For example, Chinese patent 200420066811.3, Chinese patent 200620054116.4; and; no matter whether this fan install protecting jacket or isolation mounting, all needs bigger flabellum, could allow indoor air flows; the more powerful motor of so same needs; not only take the very big interior space, also consumed a large amount of electric energy, because this electric fan volume is big; manufacture cost is big, does not both uneconomically also save.And these fans are easy to generate big noise in indoor environment.And uneven air.
Another kind of fan is a kind of fan that produces wind by centrifugal fan, this fan mainly adopts centrifugal air-out structure, air-out is to realize by centrifugal blower, Chinese patent CN283669Y for example, CN2833186Y etc., this fan almost is the distortion of centrifugal fan, but this fan drives the rotating mechanism of wind more and is arranged in the housing, can not hurt sb.'s feelings because of flabellum, that even amplitude of fluctuation is set is little for the blade of this fan in addition, has avoided the wearing and tearing of motor and miscellaneous part, and running steadily, noise is relatively little, life-span is big relatively, still, this fan be centrifugal, the internal structure more complicated, when pollutants such as dust enter in the blower fan, strengthen attached to cleaning difficulty easily, be unfavorable for keeping clean.In Chinese patent CN2740815Y, the housing designs of this fan makes air-out direction suffer restraints, and makes that the scope of wind direction is limited to.And, because of the relation that is provided with of parts, cause it to be difficult to realize the variation of wind direction in the fan.In U.S. Pat 60/641804, though the design of this turbine has been had new variation, saved the space,, the exhaust outlet of this fan is long, and is subjected to the restriction of wind inlet, causes the inhomogeneous up and down of air-out, also can't simply clean.And these fans are easy to generate big noise, uneven air in indoor environment.
Another fan, change the fan of axial fan air-out by shell, it is exactly the improved type fan that adopts tradition fan chip architecture, usually adopt the type of similar centrifugal fan, the clear 56-167897A of Japan Patent JP for example, fan in this patent be basically in this class fan early employing the flabellum of motor and fan is placed in the housing, right and wrong are centrifugal goes out wind apparatus.For example Chinese patent application 200810177844.8,200910175867.X, 200810177843.3, U.S. Pat 5881685A, US20080247881A 1, these fans all are to adopt brushless electric machine to drive flabellum to produce wind, realize air-out by specific housing, internal structure and exhaust outlet setting, the exhaust outlet of this fan can be realized the wide-angle air-supply.Though this fan is arranged on inside with flabellum, utilize the draught head of exhaust outlet to drive the air-flow that the surrounding atmosphere generation continues, this fan only has one group of impeller, therefore, have the phenomenon of blast deficiency during use, wind is disperseed easily, can not concentrate object of aligning to blow, the distance of air-supply also falls short of, and having limited exhaust outlet must be very narrow, reduces air-out area, could guarantee pressure, form huge noise, therefore, the General of this fan is unsatisfactory.
Chinese patent 200910175867.X discloses a kind of on-bladed fan component that is used to form air-flow, this fan component comprises device and the nozzle that is used to form air-flow, this nozzle comprises the mouth inner passage and that be used to launch air-flow that is used to receive air-flow, nozzle extends around an axis, to limit an opening, dragged suction from the fan component air outside from the air-flow of described mouth emission and passed through opening, nozzle comprises a surface, mouth is set on this surface with steering flow, this surface comprises diffusion section and guide portion, this diffusion section is taperedly away from described axis, and this guide portion is also angled with it in the diffusion section downstream.For another example, Chinese patent 201010130004.3,201010129573.6,201010129802.4 etc., the design deficiency of these patents is to be provided with little inlet air hole around the cylindrical shape blower-casting, also can form the rotary air noise, also be difficult to clean, fan electromotor needs very high rotating speed, forms bigger set noise or machine vibration, and expends very big electric energy.
Chinese patent 201020129722.4 relates to a kind of no flabellum fan, comprises fuselage, is provided with motor in fuselage, the fuselage below is provided with base, in fuselage, and above motor, be provided with fan, be provided with the cloth vane at body upper, its advantage is simple in structure, safe in utilization, volume is little, is blown by fuselage, the wind of sending is softer, and noise is little.But this fan also produces set noise and vibration because of high motor speed.And for example, Chinese patent 201010223705.1 discloses a kind of multifunctional super-silent fan, and fan comprises power supply, base, supporting base, first wind component, second wind component.Wherein, the acute angle of the formed angle in plane that forms between the interior ring of first wind component and the outer shroud and plane, fan place is the 65-80 degree; The diameter in the hole of intake grill increases from top to bottom successively on the base, have exhaust outlet on second wind component, second exhaust outlet identical big or small identical with first wind component distance, but still adopted high-revolving motor in this patent, the set noise and the vibration that still exist motor rotation itself to produce.Therefore, fan of the prior art exist noise big, be difficult to clean and the shortcoming of high energy consumption.
