Abstract
The utility model relate to an air conditioner the accessory. An idle call 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 is the thick inner thin airfoil in outer end, the diameter of through -flow fan blade is A, and blade inner arc size is different with blade outer arc size, and blade inner arc size is 0.1~0.12A, and blade outer arc size is 0.1~0.13A, and the blade chord length is 0.2~0.3A, and blade outer end thickness is 0.1~0.15A, and the inner thickness of blade is 0.03~0.06A. The advantage of this through -flow fan blade has increased the amount of wind, and blade intensity has obtained the improvement, has reduced the breakage rate and the noise of product.
Description
Technical field
The utility model relates to a kind of air conditioner parts, especially through-flow fan blade.
Background technique
Idle call fan blade processes 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.Current idle call fan blade vaned interior outer end thickness be basically identical, its deficiency is that air quantity is little, and blade strength is low, and product breakage rate is high.
Summary of the invention
The purpose of this utility model is to solve existing idle call fan blade above shortcomings, providing a kind of novel structure, and air quantity is large, and blade strength is high, product breakage rate and the low idle call fan blade of noise.
In order to realize above-mentioned object, the utility model have employed following technological scheme:
A kind of idle call fan blade, comprise the blade of multiple connection, middle joint is made up of circular wheel disc and polylith blade integrated injection molding, and blade one end and circular wheel disc are connected as a single entity, and blade is the thin airfoil in thick the inner, outer end; The diameter of through-flow fan blade is A, and blade concavity size is different from blade outer arc size, and blade concavity size is 0.1 ~ 0.12A, blade outer arc size is 0.1 ~ 0.13A, blade chord length is 0.2 ~ 0.3A, and blade outer end thickness is 0.1 ~ 0.15A, and the inner thickness of blade is 0.03 ~ 0.06A.
As preferably, the distance between not all adjacent blades is all identical, further eliminates surge sound of the wind.
Have employed the idle call fan blade of above-mentioned technological scheme, blade is the thin airfoil in thick the inner, outer end, blade concavity size is different from blade outer arc size, blade concavity size is 0.1 ~ 0.12A, blade outer arc size is 0.1 ~ 0.13A, blade chord length is 0.2 ~ 0.3A, blade outer end thickness is 0.1 ~ 0.15A, the inner thickness of blade is 0.03 ~ 0.06A, the blade of said structure size adds the air pressure of blade face, reduce the resistance of blade outer arced surface, thus the effective air quantity increasing through-flow fan blade, the advantage of this through-flow fan blade is the increase in air quantity, blade strength is improved, reduce damage percentage and the noise of product.
Accompanying drawing explanation
Fig. 1: the structural representation of the middle joint of the utility model embodiment.
Fig. 2: the enlarged diagram of the utility model embodiment Leaf.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, embodiment of the present utility model is made a detailed explanation.
A kind of idle call fan blade as depicted in figs. 1 and 2, 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.Distance between not all adjacent blades is all identical, and namely blade 1 is not equidistant arrangement, can reduce noise.
The diameter of through-flow fan blade is A, and blade 1 is the thin airfoil in thick the inner, outer end.Inner arc 11 size of blade 1 is different from outer arc 12 size, inner arc 11 size is 0.1 ~ 0.12A, and outer arc 12 size is 0.1 ~ 0.13A, and the chord length L1 of blade is 0.2 ~ 0.3A, the inner thickness L3 of blade 1 is 0.03 ~ 0.06A, and blade 1 outer end thickness L2 is 0.1 ~ 0.15A.
Take model as the through-flow fan blade product of 97.8-35-625.6 be example, diameter is A is 97.8mm, and length is 625.6mm, and blade quantity is 35, and weight is 515g.The vane thickness of existing conventional through-flow fan blade is identical, circular runout 0.45mm, axial runout 0.3mm; Amount of unbalance: left side is 0.09g, right side is 0.07g; Air quantity is 550m3/h, and noise is 43dB, and individual blade intensity is 80N.Adopt the through-flow fan blade of the art of this patent, inner arc 11 size is 9.78 ~ 11.736mm, and outer arc 12 size is 9.78 ~ 12.714mm, the chord length L1 of blade is 19.56 ~ 29.34mm, and the inner thickness L3 of blade 1 is 2.934 ~ 5.868mm, and blade 1 outer end thickness L2 is 9.78 ~ 14.67mm, circular runout 0.35mm, axial runout 0.25mm, amount of unbalance: left side is 0.06g, right side is 0.09g, air quantity is 605m3/h, noise is 42dB, and individual blade intensity is 100N, effectively reduces product breakage.
