Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment one shown in Fig. 1, this low noise air-conditioning internal machine includes tubular axial-flow fan 1, the end of described axial-flow fan 1 has fresh air inlet 10, along axis, there is rotating shaft 11, this axial-flow fan 1 is driven by fan electromotor (in Fig. 1 not shown), when axial-flow fan rotates, air-flow enters inside axial-flow fan from end, and radially discharges；Described axial-flow fan 1 is provided externally with opening cylinder 2 coaxial with axial-flow fan, with axial cut-outs 20, and the air-flow that described axial-flow fan 1 is radially discharged is discharged from the axial cut-outs 20 of described opening cylinder 2；Described opening cylinder 2, by steering control system control, makes opening cylinder 2 can rotate around the axis that opening cylinder 2 and axial-flow fan 1 are common.
It addition, the outside turnup of lower edges of the axial cut-outs 20 of described opening cylinder 2, forming arc crimping 201, so that the air-flow that axial-flow fan 1 is discharged flows through sleekly from described axial cut-outs 20, namely air-flow is not formed sharp keen otch by axial cut-outs 20.
Above-mentioned low noise air-conditioning internal machine is when outside air-out, described axial-flow fan 1 air-flow discharged can only be discharged from the axial cut-outs 20 of described opening cylinder 2, therefore, by regulating the corner of opening cylinder 2, can realize the adjustment of wind direction；Regardless of whether what kind of angle is axial cut-outs 20 be rotated in, the lower edges of axial cut-outs 20 is symmetrical (air-out of axial-flow fan 1 is uniform about its axis circumference) all the time for exhaust airstream, is therefore absent from the vibrating noise caused by asymmetry；On the other hand, due to the lower edges not object gas flow all the time of axial cut-outs 20, therefore axial cut-outs 20 to air-flow substantially without the effect of isolating, so being substantially free of air-flow to tear noise；So that this air-conditioning internal machine remains relatively low wind noise.
