Description

Multifunctional-noise fan Technical Field The present invention relates to a fan generating the air flow control means and, more particularly, to ultra quiet fan blades without multifunction electronic remote control of the fan. Background technique

A fan to allow air circulation and flow through to take away the heat of the cooling device, is a traditional, environmentally friendly indoor appliances. Fan according to the way the wind different types can be divided into three types, one is directly driven by the motor disturbance axial fan air flow around the axis of rotation a plurality of blades, the fan is a conventional common fan forms, including a fan and fan desk fan like configuration, this multi-fan blades exposed to the outside, preventing the blade from falling to wounding, or to prevent access to the blade outside the object, some of the protective sheath is generally provided around the blade Alternatively isolation device, or a high fan hanging up, away from the crowd. Such perturbations to direct air through the fan blades usually conventional AC motor is driven, and the use of large knife-like blades, which produces a loud noise. For example, Chinese Patent Applications

200 820 002 255. If a protective sheath is provided on the outside of the blade, the more prone to noise, and obstruct the gas flow, the effect of reducing the flow of the wind. For example, Chinese patent 200 420 066 811, 200 620 054 116 Chinese patent. And, whether or not such a fan installed protective sleeve or isolation device, they require relatively large blades can make indoor air flow together, so that also needs greater motor power, not only take up much interior space, but also consumes a lot of power, because such fans bulky, manufacturing cost, neither economical nor savings. And these fans in the indoor environment, prone to loud noise. And blowing uneven.

Another fan is a centrifugal fan air generated by a fan, which is mainly a centrifugal fan wind structure, the wind is achieved by centrifugal fans, such as China patent CN283669Y, CN2833186Y and so on, which is a centrifugal fan is almost deformation fan rotation mechanism, but such a multi-drive wind fan disposed within the housing, the fan will not be hurt, such additional fan blades disposed uniformly small amplitude swing, to avoid the wear of the motor and other components, smooth operation, noise is relatively small, the life is relatively large, however, it is a centrifugal, more complex internal structure of this fan, when the dust and other contaminants into the fan, the more difficult to clean easily attached, which is detrimental to clean. Chinese patent CN2740815Y, the design of such a fan housing such that the wind direction is constrained, such that the blowing angle range is limited. Further, since the arrangement relationship in the fan member, which is difficult to cause a change in the angle of the blowing. In U.S. Patent No. US60 / 641804, although with the new changes to the design of such a turbine, saves space, but such long fan outlet, the air inlet is limited, resulting in an uneven vertical wind, It can not be a simple cleaning. And the fan in an indoor environment, is easy to produce large noise, blowing uneven.

A fan then, the housing is changed by axial fan wind fan, the fan is improved using a conventional fan-sheet structure, usually similar type of centrifugal fan, for example, Japanese Patent Publication JP 56-167897A, this patent such a fan is substantially fan earlier apparatus employs an air motor and fan blades disposed within the housing, a non-centrifugal type. For example Chinese patent application No. 200810177844. 8, 200910175867. X, 200810177843. 3, U.S. Patent US5881685A, US20080247881A1, the fan blades are driven by a brushless motor wind is generated, by a specific case, the internal structure and outlet disposed to achieve the wind, the fan can have a larger angle of the outlet air, although this fan blades disposed therein, ensure the safety of the fan, but the fan inlets disposed only in the lower portion of the base , the small air, even before and after the gas flow during operation of the convection fan outlet formed therein is formed around the base of the fan of a different pressure difference, caused by the flowing gas stream is not uniform, the noise is formed. This fan with a circular or oval outlet, may be provided, although any proportion between the outlet (nozzle) and the base, but, in practice, a specific proportional relationship is likely to cause instability of the fan is placed, and these proportional to the wind can not be effectively more distance. Such fan outlet to use more commonly used in the fluidics Ke Enda surface is provided, but the fan outlet using this surface strictly binding to the entire wind flow fan system to produce good results, otherwise the wind uniform, and noise is low efficiency. And this fan is directed through the Ke Enda surface, in fact, the application of Ke Enda effect Coanda effec also known as the Coanda effect). By a fluid (water or air flow) would have to leave the direction of flow, with a tendency to a convex surface of the flow of the object, when there is friction between the object surface and the surface of the fluid as it flows through the fluid flow rate will slow down , as long as not too large curvature of the object surface, based on the Bernoulli principle of fluid mechanics, the flow rate of the slow flow will cause fluid to be adsorbed on the object surface. Thus this use of the Ke Enda effect of the fan outlet air tightly attached to the surface of the outlet, but the wind is easily dispersed, and focused on an object can not be blown from the blower is not long enough, and the noise, the combined effect of not ideal. These types of fans are mechanical control, not smart enough.

The present invention is achieved by a set of three kinds of the advantages of the prior art fan, a structure in a simple design, multiple functions may be uniformity of the wind, but also long-distance transport of wind fan, a large angle of wind, and the small volume of the fan, super silent, easy to clean fan.
