Abstract
The utility model discloses a through-flow fan blade for an air conditioner, comprising a disc-shaped impeller and fan blades vertically welded on the outer periphery of the impeller, wherein the fan blades divide the outer periphery of the impeller into a plurality of arc sections, and arc length of the two adjacent arc sections is not equal. In the utility model, the fan blades are unevenly distributed on the impeller, so that the probability of forming vortex is reduced, wind dryness is further reduced, the wind efficiency is improved, the outlet air is more uniform, the noise of the air conditioner is lower, and a user feels more comfortable.
Description
Technical field
The utility model relates to a kind of through-flow fan blade, is specifically related to a kind of through-flow fan blade of idle call.
Background technique
Existing through-flow fan blade comprises a discoid impeller and vertically is welded in blade on the described impeller outer circumference, all blades are evenly distributed on the excircle of described impeller, that is: blade evenly has been divided into a plurality of arc sections with the excircle of impeller, and the length of each arc section is identical.
According to the fluidics principle, above-mentioned through-flow fan blade structure is easy to form eddy current in spiral case, thereby makes wind-dryness bigger.
The model utility content
In order to solve the existing bigger problem of through-flow fan blade wind-dryness, the utility model purpose has been to provide a kind of wind-dryness littler through-flow fan blade.
For achieving the above object, the technical solution of the utility model is:
A kind of through-flow fan blade comprises a discoid impeller and vertically is welded in blade on the described impeller outer circumference that described blade is divided into a plurality of arc sections with the excircle of impeller, and the arc length of two described arc sections that all are adjacent is unequal.Promptly be: the angle between the two adjacent radiuses is unequal, and described radius is that the point of same position on all blades is with the formed radius of the line in the impeller center of circle.
Preferably, the length of all arc sections is 1/36～13/360 of described impeller outer circumference, that is to say: the angle between the two adjacent radiuses is between 10 degree～13 degree, and described radius is that the point of same position on all blades is with the formed radius of the line in the impeller center of circle.
Best, the number of described arc section is 30 sections, promptly be: the lobe numbers that is distributed on the impeller inner peripheral wall is 31, that is to say: the angle between the two adjacent radiuses is about 12 degree, and described radius is that the point of same position on all blades is with the formed radius of the line in the impeller center of circle.
The utility model employing blade is non-uniformly distributed in the structure on the impeller, thereby has reduced the possibility that eddy current forms, and then reduces wind-dryness, raising wind effect, can make air-out more even, and the air-conditioning noise is lower, allows the user feel more comfortable.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is a plan view of the present utility model.
Among the figure:
1, impeller 2, blade
3, arc section
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
As shown in Figure 1, the utility model discloses a kind of through-flow fan blade, comprise a discoid impeller 1 and vertically be welded in blade 2 on described impeller 1 excircle, described blade 2 is divided into a plurality of arc sections 3 with the excircle of impeller 1, and the arc length of two described arc sections 3 that all are adjacent is unequal.That is to say: the angle difference between the two adjacent radiuses, as α among the figure and β angle, described radius is the line formed radius of the point of same position on all blades 2 with impeller 1 center of circle.
As shown in Figure 1, in order both to guarantee the advantage of existing through-flow fan blade, overcome the big problem of its wind-dryness again, the length of all arc sections 3 is 1/36～13/360 of described impeller 1 outer circumference.That is to say: the angle between the two adjacent radiuses is between 10 degree～13 degree, and described radius is the line formed radius of the point of same position on all blades 2 with impeller 1 center of circle.
As preferred forms of the present utility model, as shown in Figure 1, the number of described arc section 3 is 30 sections, promptly be: blade 2 numbers that are distributed on impeller 1 inner peripheral wall are 31, that is to say: the angle between the two adjacent radiuses changes about 12 degree, and described radius is the line formed radius of the point of same position on all blades 2 with impeller 1 center of circle.
As shown in Figure 1, blade 2 of the present utility model is non-uniformly distributed on the impeller 1, thereby has reduced the possibility that eddy current forms, and then reduces wind-dryness, raising wind effect, can make air-out more even, and the air-conditioning noise is lower, allows the user feel more comfortable.
More than technological scheme that the utility model embodiment is provided be described in detail, used specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as restriction of the present utility model.
