Embodiment
For making the purpose of this utility model, feature, advantage can be more obvious and understandable, below in conjunction with the accompanying drawing in this specific embodiment, technological scheme in the utility model is clearly and completely described, obviously, the embodiments described below are only the utility model part embodiments, and the embodiment of not all.Based on the embodiment in this patent, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of this patent protection.
Present embodiments provide a kind of centrifugal wind wheel of air cleaner, refer to Fig. 1 and shown in composition graphs 2, comprising: base plate 1, cover plate 2 and multiple blade 3; Multiple blade 3 is located on base plate 1, cover plate 2 is covered on multiple blade 3, the center of base plate 1 is provided with the axis hole 4 for mounted motor axle, and multiple blade 3 to be equally spaced spread configuration along the circumference of base plate 1, and the give vent to anger exit angle β scope of face and base plate 1 tangent direction of blade 3 is 90 ° ~ 160 °.
Like this because the give vent to anger exit angle β of face and base plate 1 tangent direction of blade 3 increases, the resistance going out one's intention as revealed in what one says reduces, and air quantity increases, and air-out efficiency increases, and then reduces noise.
Larger exit angle β, makes the wind-force of blade 3 in flow process, and loss reduces, best results when exit angle β selects 137 °.
In an embodiment, the structural design of blade arc shape, the thickness of blade 3 intermediate portion is greater than the thickness of airflow outlet end and the thickness of airflow inlet end respectively.The thickness of such blade 3 intermediate portion can give the integrally-built support of blade 3, prevents blade 3 to be in use out of shape, also reduces the frictional loss of impeller passage, reduces energy consumption.Through contrast test, this structure air quantity under equal energy consumption adds the air quantity of 20% than common blade 3.
In an embodiment, the distance of the airflow inlet end of the blade 3 that two positions are relative and the ratio of base plate 1 diameter are close to one.Concrete, refer to the distance that D1 in shown in Fig. 1 is the airflow inlet end of the relative blade 3 in two positions, D2 is base plate 1 diameter, here according to formula:
known: to adopt higher diameter to compare D
1/ D
2, can guarantee that the angle of attack change of airintake direction is little, reduce the impact loss caused because the air-flow angle of attack does not wait.
Such as: base plate 1 diameter D
2for 282.6mm, D
1design is decided to be 243.7mm.β selects 137 °, goes out by above-mentioned formulae discovery the optimum value that blade 3 is about 40, can reduce exit flow deflection like this, improve theory and the actual pressure of wind wheel, reduces the impact of relative eddy.
