Interior through-flow fan blade 1, air channel 2 include the first training wall 4 and the second training wall 5 being oppositely arranged, and air channel 2 has air outlet 3, passed through
The length for flowing fan blade 1 is L1, and the length of air outlet 3 is L2, and the width of air outlet 3 is a1, and the width of air outlet 3 is the first water conservancy diversion
Minimum range between the internal face of the internal face of wall 4 and the second training wall 5, the relation between L1, L2 and a1 meet：L1=a*
L2-b*a1+c, wherein a scope are 1.151~1.165, it is preferable that a 1.15883；B scope is 1.449~1.459,
Preferably, b 1.45414；C scope is 41.11~41.21, it is preferable that c 41.16452；L1 ＞ L2 ＞ a1.
By above-mentioned mode, can reasonably limit through-flow fan blade 1 length and air outlet 3 length and width it
Between relativeness so that indoor set can have a more rational air exhausting structure, on the basis of reducing air inlet/outlet loss
It can ensure that air-conditioning from air-out performance, reduces wind noise.
Preferably, the relation between L1 and L2 meets：15≤L1-L2≤25mm, the length of air outlet can be effectively prevented from
The difference spent between L2 and the length L1 of through-flow fan blade 1 is excessive, and causes the air-supply efficiency of through-flow fan blade 1 to reduce so that through-flow
The air-out of fan blade 1 more efficiently can flow out through air outlet 3, improve the air-out efficiency of air outlet, while can reduce air-out
Resistance, reduce wind noise.
Preferably, the relation between L2 and a1 meets：0.1257≤a1/L2≤0.1284, enable to the length of air outlet 3
Wide ratio is arranged in a rational scope so that air outlet 3 has the air exhausting structure of more Aspect Ratio, ensures air outlet
3 air-out performance, reduce fan resistance of the air outlet 3 to through-flow fan blade 1.
Preferably, the length range of through-flow fan blade 1 is 900~950mm.
Preferably, the width range of air outlet 3 is 110~120mm.
Preferably, the air-out passage in air channel 2 is incremented by along air-out direction section, air along air-out passage flow out when, go out
Demeanour encloses gradual increase, each place of interior can be more rapidly reached after air outlet 3 is left so that indoor temperature
It can quickly be adjusted, improve temperature adjustment efficiency.
Preferably, a diameter of D of through-flow fan blade 1, L1*D/ (L2*a1)=1.016~1.029, can make through-flow fan blade 1
Air output and air outlet air-out area between form good matching relationship so that the air-out of through-flow fan blade all the time can be most
Blown out from air outlet to big degree, reduce air outlet to through-flow fan blade.
Preferably, on the section of through-flow fan blade 1, the center of through-flow fan blade 1 is with the first training wall 4 away from through-flow fan blade 1
The distance of the inward flange of side is the inward flange of L3, the center of through-flow fan blade 1 and the second training wall 5 close to the side of through-flow fan blade 1
Distance be L4, inward flange of second training wall 5 close to the side of through-flow fan blade 1 is the second training wall 5 relative to the first training wall 4
