Description
Technical field
The present invention relates to a kind of fan and control gear thereof that can produce air-flow, especially relate to super-silent and do not have the multifunction electronic telecontrol fan of electric fan.
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, and adopt large stretch of cutter shape flabellum, can produce huge noise like this by flabellum.For example, Chinese patent application 200820002255.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, Chinese patent 200620054116.And; no matter whether this fan install protecting jacket or isolation mounting; all need bigger flabellum; could allow indoor air flows, the more powerful motor of so same needs not only takies 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, US20080247881A1, these fans all are to adopt brushless electric machine to drive flabellum to produce wind, by specific housing, internal structure and exhaust outlet setting are realized air-out, the exhaust outlet of this fan can be realized the wide-angle air-supply, though this fan is arranged on inside with flabellum, guaranteed the safety of fan, but this fan only has been arranged on wind inlet the lower middle portion of pedestal, inlet air is young, and front and back are even, and the airflow convection that wherein exhaust outlet forms in the fan work process forms different draught heads around fan base, cause flowing of air-flow also inconsistent, form noise.This fan has adopted circular or oval-shaped exhaust outlet, exhaust outlet (nozzle) though and between the base any proportionate relationship can be set, but, in the practice, specific proportionate relationship causes the placement instability of fan easily, and these proportionate relationships can not effectively be delivered to wind distance comparatively far away.The coanda surface that this class fan outlet adopts in the fluidics more and used always is provided with, but adopt this surface must strict running system to combine at the exhaust outlet of fan and could produce good effect with wind whole fan, otherwise air-out is inhomogeneous, and noise is big, and efficient is low.And in the relating to of this fan by the coanda surface, in fact used Coanda effect Coanda effect(and be also referred to as Coanda effect).Be to have by fluid (current or air-flow) to leave original flow direction, change the mobile tendency of protruding with work of body surface into, when having surface friction between the body surface that fluid and it are flow through, flow rate of fluid can slow down, as long as the curvature of body surface is not too big, according to the bernoulli principle in the fluid mechanics, the slowing down of flow velocity can cause fluid to be attracted on the body surface flowing.Therefore this wind that utilizes the fan outlet of Coanda effect tightly is attached to the surface of outlet, but wind is disperseed easily, can not concentrate to aim at an object and blow, and the distance of air-supply also falls short of, and noise is big, and General is unsatisfactory.These several fans all are machinery control, intelligence inadequately.
The present invention is by gathering the advantage of three kinds of fans of the prior art, designs a kind of simple in structurely, and function is many, and is can air-out even, can carry the fan of wind again at a distance, and wide-angle air-out, and the fan volume is little is super-silent, easily the fan that cleans.
