Abstract
The utility model relates to a centrifugal wind wheel which increases the amount of input air of the wind wheel by adding an inlet opening. The prior centrifugal wind wheel adopts the technology of unilateral inlet opening. The technical proposal provided by the utility model is that the centrifugal wind wheel is a bilateral wind absorption wind wheel, which comprises a hub, a spoke and a plurality of main blades, wherein, the outer edge of the spoke is extended to form an interconnecting piece which supports one ends of the main blades. The utility model is characterized in that a plurality of auxiliary blades, which are distributed annularly and arrayed in the same direction as the main blades, are positioned on the other side of the interconnecting piece of the spoke. By adopting the structure of the utility model, the auxiliary blades are positioned on the bottom of the prior wind wheel, and wind current can enter a wind wheel chamber from the inlet opening formed by the auxiliary blades. Compared with the design of the unilateral inlet opening of prior art, the utility model is expanded to the structure with the bilateral wind inlet openings, thus increasing the input air parameter of the wind wheel on even ground.
Description
[affiliated technical field]
The utility model relates to a kind of member of air-stream generating device, centrifugal wind wheel specifically.
[background technique]
The working principle of the blower fan that centrifugal wind wheel is housed of prior art is: prime mover drives the centrifugal wind wheel high speed rotating by axle, air-flow is axially entered the centrifugal wind wheel chamber of high speed rotating by the single admission mouth, thereafter air-flow is accelerated and radially flows out the centrifugal wind wheel chamber, and for example the disclosed scheme of the model utility of publication number CN2580159Y is exactly to adopt the technology of this single admission mouth.
[summary of the invention]
In order to make wind wheel that bigger air quantity parameter is arranged under the identical condition of wind wheel volume, it is a kind of by increasing the centrifugal wind wheel that intake grill improves the wind wheel air quantity that the utility model provides.
The technological scheme that the utility model adopted is: a kind of bilateral air draught wind wheel, comprise wheel hub, spoke and some primary blades, the spoke outer rim is radially extending into the joint that supports primary blades one end, it is characterized in that the auxiliary blade that the opposite side of spoke joint is provided with some annular distribution and arranges in the same way with primary blades.After adopting such structure, owing to be provided with auxiliary blade in original wind wheel bottom, distinguished and admirablely also can enter the wind wheel chamber from the intake grill that this auxiliary blade forms, the folk prescription of original technology of comparing is just expanded as the bilateral air inlet structure to the intake grill design, thereby has under equal conditions improved the air quantity parameter of wind wheel.
As preferred scheme, auxiliary blade primary blades with opposite side on the spoke joint is spaced; Auxiliary blade is corresponding one by one with primary blades.
It is bowl-shape that spoke is, and its recess is towards the auxiliary blade end; And offer six through holes on the spoke, also be formed with radial stiffening rib on it.Adopt this structure just effectively to strengthen the structural strength of spoke.
In addition, for the centrifugal wind wheel of unidirectional rotation, its primary blades and auxiliary blade are in the same way and arrange.For the centrifugal wind wheel of two-way rotation, its primary blades and auxiliary blade are divided into forward blade and backward vane.
The beneficial effects of the utility model: be provided with auxiliary blade in original wind wheel bottom, distinguished and admirablely also can enter the wind wheel chamber from the intake grill that this auxiliary blade forms, the folk prescription of original technology of comparing is just expanded as the bilateral air inlet structure to the intake grill design, thereby has under equal conditions improved wind wheel air quantity parameter.

[embodiment]
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail:
A kind of bilateral air draught wind wheel shown in Fig. 1,2,3,4,5,6,7, comprise wheel hub 1, spoke 2 and primary blades 3, spoke 2 outer rims are radially extending into the joint 4 that supports primary blades 3 one ends, the other end of primary blades 3 is fixed on the bracing ring 5, the opposite side of spoke 2 joints 4 be provided with some annular distribution and with primary blades arrange in the same way auxiliary blade 6.It is bowl-shape that spoke is, and its recess is towards the auxiliary blade end; And offer six through holes 7 on the spoke, also be formed with radial stiffening rib 8 on it.After adopting such structure, owing to be provided with auxiliary blade in original wind wheel bottom, air-flow also can enter the wind wheel chamber from the intake grill that this auxiliary blade forms, the folk prescription of original technology of comparing is just expanded as the bilateral air inlet structure to the intake grill design, thereby has under equal conditions improved the air quantity parameter of wind wheel.
In addition, auxiliary blade 6 is spaced with the blade 3 of opposite side on spoke 2 joints 4.The spaced benefit of auxiliary blade is that the air-flow that enters the wind wheel chamber from the bottom is steadily mixed with the air-flow that top enters.
Owing to be unidirectional rotation, the primary blades of centrifugal wind wheel and auxiliary blade are in the same way and arrange thus for present embodiment.Centrifugal wind wheel is the structure of two-way rotation in the actual conditions, and primary blades and auxiliary blade include forward blade and backward vane (also can be forward working surface and reverse operation face).
