Compared with the prior art, the utility model has the advantages of: the radial stator that this stator formula impeller distributes along the circumferencial direction through the interior week setting at the front end housing in proper order for the inside air current of impeller is more smooth and easy, reduces the turbulent flow, simultaneously because radial stator can rotate and produce the linkage along with the fan, therefore this radial stator can also be in the same direction as bringing the air current acting, thus the whole efficiency of increase fan.
Description
Technical field
The utility model relates to a kind of draught fan impeller, especially relates to a kind of guide-vane impeller.
Background technique
Range hood has become the requisite kitchen appliance of family, and it is primarily of casing and inner multi-wing centrifugal fan composition.Multi-wing centrifugal fan is the core component of range hood, and the impeller of blower fan plays the effect of transformation of energy, and the quality of impeller performance directly affects the performance of range hood.During impeller work, after air-flow enters multi-wing centrifugal fan impeller internal, a segment distance is needed to realize by axial to radial conversion, from impeller front disc to impeller central disc, along with the minimizing that leaf is high, air-flow radial velocity increases gradually, axial velocity reduces gradually, so, cause airflow inlet air horn to increase, the angle of attack reduces.At present, general multi-wing centrifugal fan prismatic blade has airflow breakaway in the blade passage near impeller front disc, causes Flow Field Distribution to be destroyed, and the air quantity of range hood reduces, further, be separated by blade air the important component part that the noise produced also is range hood noise.In addition, traditional multiple wing leaf centrifugal blower, because blade inner and outer diameter ratio (D1/D2) is substantially all between 0.8-0.9, thus causes in blade more chaotic through the air-flow toward interior part, lacks effective combing mode.In sum, need to be done into an improvement the blade wheel structure of existing centrifugal blower.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, provides a kind of and makes impeller internal air-flow more smooth and easy and reduce turbulent guide-vane impeller.
The utility model solves the problems of the technologies described above adopted technological scheme: this guide-vane impeller, comprise the impeller plate, front cover and rear end cover, described front cover is ring and is arranged on the front-end face of the described impeller plate, described rear end cover is ring and is arranged on the ear end face of the described impeller plate, it is characterized in that: the inner circumferential of described front cover is circumferentially distributed with at least 3 radial stators successively.
Preferably, described radial stator has axial extension part and radial extension part, and described axial extension part extends forward from the inner periphery of described front cover, and described radial extension part extends internally from the front side edge of axial extension part.
Preferred further, described radial extension part all produces deflection relative to the end face of described front cover and deflection direction is consistent.
The quantity of radial stator can have multiple choices, and preferably, described radial stator has 4 ~ 6.
In order to effective combing blower interior air-flow, the described impeller plate comprises shroud and middle hub disk, in described hub disk front side card on be circumferentially distributed with the axial stator of a circle, and the length direction of described axial stator is parallel to the rotating shaft of described middle hub disk.
Further preferably, described shroud has shroud blade, and described middle hub disk has mid-game blade and hub disk blade, and described shroud blade and described mid-game blade stagger mutually, and described mid-game blade and hub disk blade stagger mutually.After the blade employing dislocation type design of middle hub disk, when can ensure on the one hand injection moulding, raw materials for plastics production more easily flow into each leaf area, reduce quality problems, the time difference of exit flow can be formed on the other hand on impeller axial direction, reduce the noise that exit flow causes.
Further preferably, described front cover, shroud, middle hub disk and rear end cover are integrated injection molding part, the trailing flank of described front cover has the first draw-in groove inserted for described shroud blade, the trailing flank of described shroud has the second draw-in groove inserted for described mid-game blade, the leading flank of end cap in the rear has the 3rd draw-in groove inserted for described hub disk blade.Like this, between front cover and shroud, between shroud with middle hub disk and middle hub disk can carry out ultrasonic welding easily with between rear end cover or bonding time locate and be connected.
Compared with prior art, the utility model has the advantage of: this guide-vane impeller is by arranging in the inner circumferential of front cover at least 3 radial stators circumferentially distributed successively, make impeller internal air-flow more smooth and easy, reduce turbulent flow, produce interlock because radial stator can rotate along with blower fan simultaneously, thus this radial stator along bringing air-flow acting, thus can also increase the whole efficiency of blower fan.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1 to Figure 3, the guide-vane impeller in the present embodiment comprises the impeller plate, front cover 1 and rear end cover 4, and front cover 1 is ring and is arranged on the front-end face of the impeller plate, and rear end cover 4 is ring and is arranged on the ear end face of the impeller plate.
Particularly, the impeller plate comprises shroud 2 and middle hub disk 3, and the shroud blade 21 of shroud 2 staggers mutually with the mid-game blade 31 of middle hub disk 3, and the mid-game blade 31 of middle hub disk 3 and hub disk blade 32 stagger mutually.After the blade employing dislocation type design of middle hub disk 3, when can ensure on the one hand injection moulding, raw materials for plastics production more easily flow into each leaf area, reduce quality problems, the time difference of exit flow can be formed on the other hand on impeller axial direction, reduce the noise that exit flow causes.
Front cover 1, shroud 2, middle hub disk 3 and rear end cover 4 are integrated injection molding part, the trailing flank of front cover 1 has the first draw-in groove 11 inserted for shroud blade 21, the trailing flank of shroud 2 has the second draw-in groove 22 inserted for mid-game blade 31, the leading flank of rear end cover 4 has the 3rd draw-in groove 41 inserted for hub disk blade 32.During installation, between front cover 1 and shroud 2, can ultra-sonic welded be passed through between shroud 2 and middle hub disk 3 and between middle hub disk 3 and rear end cover 4, also can be connected by cemented in place.
In the present embodiment, 5 radial stators 5 are circumferentially distributed with successively in the inner circumferential of front cover 1, the structure of each radial stator 5 is identical, radial stator 5 has axial extension part 51 and radial extension part 52, axial extension part 51 extends forward from the inner periphery of front cover 1, and radial extension part 52 extends internally from the front side edge of axial extension part 51.Further, each radial extension part 52 relative to front cover 1 end face produce deflection and deflection direction is consistent.Like this, radial stator can coordinate air inlet angle better, and parallels with the main shaft of impeller the guiding of air-flow.
