Abstract
The utility model provides an impeller of a cross-flow fan, which comprises an impeller body consisting of single-section wheels. The single-section wheels comprise two circular base plates arranged in parallel and blades, and the blades are arranged between the two base plates along the periphery directions of the base plates; the impeller body comprises one or more double-section wheels, each double-section wheel consists of an upper single-section wheel and a lower single-section wheel, blades of each upper single-section wheel are spirally arranged between an upper base plate and a middle plate clockwise, and blades of each lower single-section wheel are spirally arranged between the corresponding middle plate and a lower base plate anticlockwise. The impeller body consists of the two single-section wheels spirally arranged oppositely, axial airflow in the impeller body is reduced effectively, and accordingly energy consumption is reduced. Each two adjacent blades are axially twisted towards opposite directions, axial airflow caused by non-equidistantly distributed cross-flow fan blades and/or oblique cross flow is counteracted, and noise level is effectively reduced.
Description
Technical field
The utility model relates to a kind of impeller of cross flow fan, relates in particular to the impeller of a kind of indoor apparatus of air conditioner with cross flow fan.
Background technique
For indoor apparatus of air conditioner, its main noise source is the rotational noise of cross flow fan, the bump of air-flow and whirlpool tongue, whirlpool wall and vaporizer etc., and stream swirl noise.Existing cross flow fan extensively adopts not the equidistance vane collocation or adopts oblique through-flow fan blade; Staggered in time in positions such as airflow strikes whirlpool tongue; Can effectively the former Impact energy of certain some frequency of concentrating be dispersed in a certain frequency band; Thereby form sound of the wind a slice, reduced noise to a certain extent.But these measures have also brought distinguished and admirable inside at cross flow fan to form axial flow simultaneously, have increased energy consumption, also be prone to cause simultaneously the decline of tonequality, so its noise abatement still do not reach satisfied effect.
Summary of the invention
The utility model provides a kind of impeller that reduces energy consumption, reduces the cross flow fan of noise to deficiency of the prior art.
For solving the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of impeller of cross flow fan; Comprise the impeller of forming by the single-unit wheel; The single-unit wheel comprises two circular base plate that laterally arrange and blade, and blade is arranged between two chassis along the chassis circumferencial direction, it is characterized in that; Said impeller comprises one or more binodal wheel; Said binodal wheel is made up of last single-unit wheel and following single-unit wheel, and the blade of said upward single-unit wheel spiral along clockwise direction is arranged between top bottom-disc and the mid-game, and the blade of the said wheel of single-unit down is arranged between mid-game and the low bottom-disc along the counter clockwise direction spiral.The impeller of the utility model is made up of the single-unit wheel that two opposite direction spirals are provided with, and has effectively reduced the impeller axis to distinguished and admirable, thereby has reduced energy consumption.
In the technique scheme, the angle between said blade and the mid-game is 75 ° ~ 85 °, and the inside and outside edge of said blade is flexuose or sinusoidal.Utilize adjacent two to save sharfs, offset through-flow fan blade because the axial flow that employing is not equally spaced and/or oblique through-flow causes reaches effective reduction noise level to distortion in the opposite direction.
The utility model obtains following beneficial effect.
1, compared with prior art, the impeller of the utility model is made up of the single-unit wheel that two opposite direction spirals are provided with, and has effectively reduced the impeller axis to distinguished and admirable, thereby has reduced energy consumption.
2, utilize adjacent two to save sharfs, offset impeller because the axial flow that employing is not equally spaced and/or oblique through-flow causes reaches effective reduction noise level to distortion in the opposite direction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be Fig. 1 at A-A to sectional view.
Fig. 3 is another embodiment's of the utility model a structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1; The impeller of a kind of cross flow fan of the utility model, impeller comprise a binodal wheel 10, and binodal wheel 10 is made up of last single-unit wheel 101 and following single-unit wheel 103; Connect through mid-game 302, blade 20 along the circumferential direction is arranged between top bottom-disc 301, mid-game 302 and the low bottom-disc 303.
The blade 20 of last single-unit wheel 101 spiral along clockwise direction is arranged between top bottom-disc 301 and the mid-game 302, and the angle between blade 20 and the mid-game 302 is 75 ° ~ 85 °.
The blade 20 of following single-unit wheel 103 is arranged between mid-game 302 and the low bottom-disc 303 along the counter clockwise direction spiral, and the angle between blade 20 and the mid-game 302 is 75 ° ~ 85 °.
Referring to Fig. 2, as preferably, the inner edge 40 and the outer rim 41 of blade 20 are sinusoidal, also can be flexuose.
Referring to Fig. 3, this impeller comprises the binodal wheel 10 and binodal wheel 10 ' of two series connection, a binodal wheel 10 and binodal wheel a 10 ' public low bottom-disc 303, and blade 20 Hand of spiral of any two adjacent single-unit wheels are opposite.
Compared with prior art, the impeller of the utility model is made up of the single-unit wheel that two opposite direction spirals are provided with, and has effectively reduced the impeller axis to distinguished and admirable, thereby has reduced energy consumption.Utilize adjacent two to save sharfs, offset impeller because the axial flow that employing is not equally spaced and/or oblique through-flow causes reaches effective reduction noise level to distortion in the opposite direction.
