Description
Technical field
The utility model relates to blower fan accessory, relates to a kind of two-way taper wind wheel or rather.
Background technique
Blower fan uses comparatively extensive in field of household appliances, such as range hood, air-conditioning, heating device etc.Blower fan is a kind of driven fluid machinery, improves gas pressure to supply gas side by side body by relying on the mechanical energy of input.Wind wheel is the vitals of blower fan, drives ambient air to produce flowing by mechanical energy effect.Traditional wind wheel is one-way windwheel, this one-way windwheel air intake, and air-supply dynamics is less.Bidirection air vane compensate for the deficiency of one-way windwheel, and it is double-faced ventilated, and air-supply dynamics is comparatively large, can realize remote air-supply.
Household electrical appliances can produce noise unavoidably in the process of work, and noise is divided into mechanicalness noise and aerodynamic force noise, solve the operating noise that aerodynamic force noise just can reduce household electrical appliances effectively.At present, person skilled is studied more in ducting system noise reduction from volute of blower, often ignore wind wheel, and wind wheel is also the key working part in ducting system, and therefore the fine or not effect of depth of wind wheel structure the trend of household electrical appliances operating noise.As shown in Figure 1, the Bidirection air vane of prior art comprises wind wheeling cover, windward wheel rim and leeward wheel rim.The diameter of wind wheeling cover, windward wheel rim and leeward wheel rim is all equal.Windward wheel rim is located at the top of wind wheeling cover, is connected between the two by upper blade.Leeward wheel rim is located at the below of wind wheeling cover, is connected between the two by lower blade.Whole wind wheel is drum.There is following defect in the wind wheel of this kind of prior art: due to wind wheel cylindrically, namely every section of parallel girth (L) is all equal, and the wind speed that the parallel impact air of the inclined intermediate section of wind wheel produces is maximum, reduce gradually to wind wheel two ends expansion wind speed, namely expand towards wind wheel upper end, wind speed S1>S11>S12 ... >S1n, expand towards wind wheel lower end, wind speed S1>S21>S22 ... >S2n, this just makes the ratio deviations such as every section of parallel girth of the wind wheel of prior art and wind speed widen gradually, i.e. S1/L>S11/L>S12/LGreatT.GreaT .GT ... >S1n/L and S1/L>S21/L>S22/LGreatT.GreaT .GT ... >S2n/L.The ratio deviations such as every section of parallel girth of above-mentioned wind wheel and wind speed are larger, and air-flow is more unstable, and produce more turbulent flow, distinguished and admirable eccentricity strengthens, and increases noise.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of two-way taper wind wheel, and this two-way taper wind wheel can reduce running resistance, increases work efficiency, thus reduces mechanicalness noise and aerodynamic force noise.
Technical solution of the present utility model is, provides a kind of two-way taper wind wheel with following structure, comprises wind wheeling cover, windward wheel rim and leeward wheel rim that concentric shafts is installed; Described windward wheel rim is located at the top of wind wheeling cover and windward wheel rim is connected by upper blade with between wind wheeling cover; Described leeward wheel rim is located at the below of wind wheeling cover and leeward wheel rim is connected by lower blade with between wind wheeling cover; The diameter of described windward wheel rim and the diameter of leeward wheel rim are all less than the diameter of wind wheeling cover; Described upper blade is connected angle that plane formed for being more than or equal to 45 ° and being less than 90 ° with wind wheeling cover; Described lower blade is connected angle that plane formed for being more than or equal to 45 ° and being less than 90 ° with wind wheeling cover.
After adopting above structure, two-way taper wind wheel of the present utility model, compared with prior art, has the following advantages:
Because the diameter of windward wheel rim of two-way taper wind wheel of the present utility model and the diameter of leeward wheel rim are all less than the diameter of wind wheeling cover, upper half part of wind wheel and lower half portion is made to be taper, make wind wheel intermediate portion parallel perimeter L 1 the longest, reduce gradually to wind wheel two ends expansion parallel girth, namely expand towards wind wheel upper end, parallel L1>L11>L12 ... >L1n, towards the expansion of wind wheel lower end, parallel L1>L21>L22 ... >L2n.And the wind speed that the parallel impact air of the inclined intermediate section of wind wheel produces is maximum, reduce gradually to wind wheel two ends expansion wind speed, namely expand towards wind wheel upper end, wind speed S1>S11>S12 ... >S1n, towards the expansion of wind wheel lower end, wind speed S1>S21>S22 ... >S2n.The trend that above wind wheel parallel girth and wind wheel impact the change of the wind speed that air produces is alike, therefore, hinge structure just can reduce the ratio deviations such as wind wheel every section parallel girth and wind speed, i.e. S1/L1 >=S11/L11 >=S12/L12 >=... >=S1n/L1n and S1/L1 >=S21/L21 >=S22/L22 >=... >=S2n/L2n.The ratio deviations such as every section of parallel girth of wind wheel and wind speed are less, and air-flow is more stable, and the turbulent flow of generation is fewer, and distinguished and admirable eccentricity is less, and the noise of generation is less.
Improve as one of the present utility model, described upper blade is connected the angle that plane formed with wind wheeling cover be 60 °; Described lower blade is connected the angle that plane formed with wind wheeling cover be 60 °.This kind is designed to optimum implementation.
Improve as another kind of the present utility model, the diameter of described windward wheel rim is not less than the diameter of leeward wheel rim.
Also have a kind of improvement as of the present utility model, the diameter of described windward wheel rim equals the diameter of leeward wheel rim.This kind is designed to optimum implementation.
Also have a kind of improvement as of the present utility model, described windward wheel rim is not less than the distance of described leeward wheel rim to wind wheeling cover to the distance of wind wheeling cover.
Also have a kind of improvement as of the present utility model, described windward wheel rim equals the described leeward wheel rim distance to wind wheeling cover to the distance of wind wheeling cover.This kind is designed to optimum implementation.
