PROBLEM TO BE SOLVED: To suppress occurrence of noise caused by blowing out air-conditioning air from an indoor machine.SOLUTION: A blowout structure 11 of an indoor machine includes a plurality of louvers 7 provided in a blowout port 6 of the indoor machine and controlling a flow direction of air-conditioning air. Then, each louver 7 has a different thickness from an adjacent louver 7. Consequently, since a vortex state of air-conditioning air blown out from the blowout port 6 is made ununiform, a frequency of a vortex is dispersed, and sound pressure level of a specific frequency generating noise resulting from the fact that the vortex state is made uniform can be reduced.SELECTED DRAWING: Figure 2 |
