Abstract
The utility model relate to an air conditioner the accessory. A cross -flow fan blade, includes the blade of a plurality of connections, and the well festival is moulded plastics by ring form rim plate and polylith blade an organic whole and is constituted, and blade one end is even as an organic whole with ring form rim plate, and the blade divide into cross sectional shape different blade no. 1 and blade no. 2, and the cross sectional shape between the arbitrary adjacent blade is different, promptly blade no. 1 and two staggered arrangement in the blade, cross -flow fan blade's diameter is A, and the inner arc size of blade no. 1 is 0.1~0.13A, and the outer arc size of blade no. 1 is 0.08~0.12A, and the inner arc size of blade no. 2 is 0.1~0.14A, and the outer arc size of blade no. 2 is 0.09~0.13A. This cross -flow fan blade's advantage is novel structure, and the effectual elimination sound of the wind of surging uses the noise low.
Description
Technical field
The utility model relates to a kind of air conditioner parts, especially a kind of through-flow fan blade.
Background technique
Through-flow fan blade is one of accessory important in air-conditioning, process by saving ultrasonic welding in multiple, middle joint is made up of circular wheel disc and polylith blade integrated injection molding, blade one end and the circular wheel disc back side are connected as a single entity, circular wheel disc front is provided with multiple blades installation groove, and the quantity of blades installation groove is identical with blade quantity.The sectional shape of vaned leaf i.e. blade be all identical, its deficiency is the surge sound pitch that through-flow fan blade produces, and namely noise is large.
Summary of the invention
The purpose of this utility model is to solve existing through-flow fan blade above shortcomings, providing a kind of novel structure, the through-flow fan blade that noise is low.
In order to realize above-mentioned object, the utility model have employed following technological scheme:
A kind of through-flow fan blade, comprise the blade of multiple connection, middle joint is made up of circular wheel disc and polylith blade integrated injection molding, blade one end and circular wheel disc are connected as a single entity, the blade one that blade is divided into sectional shape different and blade two, sectional shape between arbitrary neighborhood blade is different, and namely blade one and blade two are staggered; The diameter of described through-flow fan blade is A, and the inner arc size of blade one is 0.1 ~ 0.13A, and the outer arc size of blade one is 0.08 ~ 0.12A, and the inner arc size of blade two is 0.1 ~ 0.14A, and the outer arc size of blade two is 0.09 ~ 0.13A.
As preferably, the distance between not all adjacent blades is all identical, further eliminates surge sound of the wind.
Have employed a kind of through-flow fan blade of above-mentioned technological scheme, sectional shape between arbitrary neighborhood blade is different, the diameter of through-flow fan blade is A, the inner arc size of blade one is 0.1 ~ 0.13A, the outer arc size of blade one is 0.08 ~ 0.12A, the inner arc size of blade two is 0.1 ~ 0.14A, and the outer arc size of blade two is 0.09 ~ 0.13A.Leaf different blade one and blade two is utilized to be staggered, air inlet/outlet angle curve is changed and recombinates, the surge sound produced by traditional fan blade effectively reduces or eliminates, and the change of leaf two can be utilized suitably to increase blowing area, can keep air quantity constant or increase, and effective elimination surge sound of the wind, reduces air-out sound further.The advantage of this through-flow fan blade is novel structure, and effective elimination surge sound of the wind, uses noise low.

Fig. 3: the enlarged diagram of the utility model embodiment Leaf two.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, embodiment of the present utility model is made a detailed explanation.
A kind of through-flow fan blade as shown in Figure 1, Figure 2 and Figure 3, is connected and composed by multiple middle joint, and middle joint is made up of circular wheel disc 2 and polylith blade 1 integrated injection molding, and blade 1 one end and circular wheel disc 2 are connected as a single entity.During production, in the blades installation groove saved in the blade insertion next one saved in upper, carry out ultrasonic welding.
The blade 1 that blade is divided into sectional shape different and blade 2 12, the sectional shape between arbitrary neighborhood blade is different, and namely blade 1 and blade 2 12 are staggered.Distance between not all adjacent blades 1 is all identical, and blade 1 and blade 2 12 are Unequal distance arrangements.
The diameter of through-flow fan blade is A, and the inner arc R1 size of blade 1 is 0.1 ~ 0.13A, and the outer arc R2 size of blade 1 is 0.08 ~ 0.12A, and the inner arc R3 size of blade 2 12 is 0.1 ~ 0.14A, and the outer arc R4 size of blade 2 12 is 0.09 ~ 0.13A.
Take model as through-flow fan blade Φ 94-35-608 be example, through-flow fan blade diameter A is Φ 94mm, and length is 608mm, and blade quantity is 35, and weight is 485g.Existing conventional through-flow fan blade leaf identical, circular runout 0.4mm, axial runout 0.35mm; Amount of unbalance: left side is 0.08g, right side is 0.12g, and air quantity is 560m3/h, and noise is 43dB.Adopt the through-flow fan blade of the art of this patent, the inner arc R1 size of blade 1 is 9.4 ~ 12.22mm, the outer arc R2 size of blade 1 is 7.52 ~ 11.28mm, and the inner arc R3 size of blade 2 12 is 9.4 ~ 13.16mm, and the outer arc R4 size of blade 2 12 is 7.52 ~ 11.22mm.Circular runout 0.35mm, axial runout 0.3mm; Amount of unbalance: left side is 0.1g, right side is 0.07g, and air quantity is 580m3/h, and noise is 41dB, and basic elimination surge sound of the wind, further optimization sound of the wind sound.
