Description
Technical field
The present invention relates to a kind of electric fan, especially relate to a kind of blade-free electric fan.
Background technique
Blade-free electric fan is that blade is located to internal body, and draws air-flow by connected wind channel.This fan be can't see fan blade from the teeth outwards, makes people in use, foreign matter or finger etc. can not be contacted with fan blade.The Chinese patent that is CN101713414A as publication number discloses a kind of blade-free electric fan, comprises base, casing, fan motor, centrifugation blade, blowing head, the small motor of shaking the head.Casing is connected with a blowing consubstantiality, in blowing four circle, it is hollow air channel, inferior surface of machine case has intake opening, and Fan casing is installed internal side of shell, and fan motor is arranged on casing the inside, Fan casing the inside is centrifugation blade, centrifugation blade is coaxially connected with fan motor, and jam nut is equipped with at the spindle nose place that fan motor is connected with centrifugation blade, and bottom of shell center is connected with shell axle bed, bearing is equipped with in shell axle bed the inside, and bearing inner race is connected with central shaft.Central shaft is arranged on above base, head-shaking motor is arranged on above base bottom inside, the small gear of shaking the head is connected with head-shaking motor output shaft by key pin, the gearwheel of shaking the head engages with the large small gear of shaking the head, and the gearwheel of shaking the head is arranged on above axle by pivot pin, and the other end of axle is also equipped with bearing, bearing outer ring is arranged on bearing the inside, bearing is connected with base bottom inside, and swing arm is equipped with at the gearwheel center of radius of shaking the head place, and the upper end of swing arm is flexibly connected with bottom of shell.But existing blade-free electric fan due to air channel, exhaust outlet with and the design problem of seat etc., can only be confined to bracker fan, cannot be designed to floor model structure.Cause it in family is used, to there is the inconvenience of putting, bad adaptability.And in daily life, stand fan is the most easily in children contact, the most easily there is the danger that brings because of the fan blade in motion, therefore the blade-free electric fan of floor model has more wide market prospects.
Summary of the invention
The present invention solves that prior art is existing only has mesa structure, causes the technical problem of putting inconvenience, bad adaptability, provides a kind of adaptability good, longitudinal distribution of wind is large, lateral comparison is concentrated, and air quantity is large, vertical blade-free electric fan simple in structure.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of vertical blade-free electric fan, comprise that inside is provided with the support of blower fan, the upside that it is characterized in that support is provided with inverted U air channel, this inverted U air channel is made up of both sides main wind passage and upside transition air channel, between the main wind passage of both sides, form front openings large, " eight " font structure that rear openings is little, the two ends in described transition air channel are connected with both sides main wind passage respectively, the normal direction that transition air channel is transitioned into gradually inner side surface from two ends to middle part forms an elevation angle forward and with respect to substantially horizontal, the inside back in described inverted U air channel is distributed with the exhaust outlet that is affixed on inverted U air channel madial wall.This inverted U air channel forms a long strip air-out region, and this long strip air-out region makes longitudinal distribution of air-out longer, and transverse air is to comparatively concentrated.Transition air channel is transitioned into gradually the normal direction of inner side surface and forward and with respect to the structure at an elevation angle of substantially horizontal formation wind-force is upwards drawn from two ends to middle part, further increases longitudinal distribution of wind direction.On this structure collectivity, both realize longitudinal distribution of wind direction, also ensured the air inducing length of air-flow in air channel, avoided drawing the problem cause a large amount of losses of energy because air channel is long.Both sides main wind passage "eight" shape structure, makes exhaust outlet wind out have Coanda effect, the amplification of maximum flow air-out ratio.
As preferably, described exhaust outlet is located at both sides main wind passage part.Both sides main wind passage is provided with exhaust outlet, and transition air channel does not set out the design in air port, makes air-out relatively concentrated, be conducive to amplify air output, convection action has been played in transition air channel simultaneously, and the air quantity of both sides main wind passage is supplemented mutually, has ensured that the air-out of two crosswind outlets is stable, even.Moreover this transition air channel band has played the effect of noise reduction, greatly reduce the noise of this setting.
As preferably, the exhaust outlet on the main wind passage of described every side is arranged and is formed in turn by several long strip exhaust vents, between exhaust vent spacing be 2-5mm.This structure reduces the stream effect of breathing heavily in the air channel at exhaust outlet place, has reduced noise and energy loss, has improved efficiency.
As preferably, the downside spacing of described both sides main wind passage is little, and upside spacing is little.The wind blowing out due to each position of exhaust outlet is uniformly substantially, and the downside spacing of both sides main wind passage is little, and upside spacing is large, in the case of the magnification ratio of air-out is identical, upside to go out density less, therefore, the air-out of downside must be gone up partially, can blow to the position that has that user enjoys the cool.It is too high that this structure makes that support of the present invention do not need to do, and the stability of structure is better.
As preferably, the lower end in described inverted U air channel is connected with a U-shaped bearing, inverted U air channel and U-shaped bearing integrative-structure, and the both sides of common and described support will connect, support both sides are connected with described both sides main wind passage by this connection part.Because inverted U air channel is subject to the impact of air-flow, have certain shake, and the inverted U air channel of this programme and U-shaped bearing global design, the power that inverted U air channel is impacted is direct by U-shaped bearing transmission ground, make it in use more stable, this structure is more more stable than traditional structure, and noise is also less.
As preferably, the angle before described both sides main wind passage is 20-30 °, and the normal direction of middle part, transition air channel inner side surface is with respect to the 10-15 degree at the elevation angle of substantially horizontal.
As preferably, the height overall of this fan is 50-120CM, and wherein inverted U air channel accounts for the 1/2-3/4 of fan height overall.
The beneficial effect that the present invention brings is, solved that prior art is existing only has mesa structure, causes the technical problem of putting inconvenience, bad adaptability, realized a kind of adaptability good, longitudinal distribution of wind is large, and lateral comparison is concentrated, and air quantity is large, vertical blade-free electric fan simple in structure.
