According to the improvement, performance of the 360-degree fan is improved. In addition, the 360-degree fan has the advantages of low noise, good air outlet effect and the like.
Description
Technical field
The utility model belongs to fan technical field, relates in particular to a kind of low noise 360 ° of fans.
Background technique
Conventional fan often outward appearance is general, does not possess noticeable especially characteristic, also goes up very singlely at air-out direction, often can only blow a direction, cannot ensure 360 ° can both air-out.Or need fan ceaselessly to wave, make each direction have wind, but cannot ensure that synchronization all has wind.
For addressing the above problem, there are on the market at present 360 ° of fans, it not only possesses the performance of modernization fan, has again the outward appearance of Greco-Roman Style simultaneously.Fan merges classic and modern feature.Be not only a fan, or an art work.There is metal net mask outside, plays protective action.360 ° of fans have been realized 360 ° of same moment and can have been dried.Put with on a meeting Office table, everyone can blow and obtain wind.Although current 360 ° of fan noises are less, the leaf top such as on axial leaf top and leaf top radially, causes while rotation ambient gas pulsation cause air-flow unstable due to turbine, increases rotational noise generation probability.
Therefore, consider above-mentioned situation, be badly in need of a kind of 360 ° of fan turbine device of design, when reducing the noise of turbine blade generation, can ensure 360 ° of fan entirety aeroperformances.Also the generation that has reduced in addition resonance may.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of low noise 360 ° of fans, can ensure, in 360 ° of fan entirety aeroperformance situations, to reduce the aerodynamic noise that turbine blade produces.
360 ° of fans of a kind of low noise, comprise motor, rotatingshaft, turbine, motor fixing frame, small-sized fans and netted outer cover; Netted outer cover, by turbine entirety parcel, is provided with motor on motor fixing frame, the output shaft of motor is connected with turbine by transmission shaft, and motor, motor fixing frame, rotating shaft are all arranged in pedestal; Small-sized fans is arranged in pedestal, and is directly installed on rotatingshaft and is connected with rotating shaft concentric fit, utilizes rotating shaft directly to drive this small-sized fans rotation.Described turbine comprises five blades and flat board, the camber of blade is dull and stereotyped radius 0.2 times, thickness is 4mm, blade and dull and stereotyped orthogonal, five blades equidistantly distribute, blade height is consistent with dull and stereotyped diameter, each blade is provided with noise reducing mechanism.
On the each blade of described turbine, have 6～16 blind holes, aperture is 4mm～9mm, the degree of depth of blind hole is 1/4～2/3 of vane thickness, hole pitch is 7mm, blind hole equivalent on each blade is divided into two groups, and the blind hole of every group is two rows, and is parallel to flat board and is distributed in Ye Dingchu, two groups of blind holes are symmetrical as symmetry plane taking flat board, are all 7mm apart from the nearest blind hole of leaf top and blade root and leaf top with the distance of blade root.
The each blade of described turbine is provided with multiple grooves and tongue, groove on each blade and tongue taking flat board as symmetry plane symmetrical, groove and tongue are distributed as above flat board: groove and tongue are spaced apart, the degree of depth of groove and the height of tongue are 1mm, its width is 5mm, between groove and groove, is parallel to each other, and groove and pitch of grooves are 5mm, be 8mm from the nearest groove of flat board and dull and stereotyped beeline, groove, tongue and the dull and stereotyped angle being are below 15 °.
Described small-sized fans is single rotor axial fan, double rotor axial fan or mixed flow fan.
The utlity model has following good effect: in 360 ° of fans, add Wind Volume owing to having added small-sized fans, promote air current flow by the donut of opening bottom base and motor fixing frame simultaneously, thereby improve top turbine air-out volume.The utility model, by making a call to half hole operation, has destroyed blade surface pulsating force, thereby has reduced the noise on axial leaf top, and owing to not getting through hole, thereby do not affect vane tip acting effect.By tongue and groove, change diametrically load and distributed to reduce noise, the Radial Flow that makes spaced apart of tongue and groove is more smooth and easy in addition.
