INDOOR UNIT AND AIR-CONDITIONING APPARATUS

摘要

An indoor unit includes at least one air outlet including an inner air-passage wall and an outer air-passage wall located outwardly of the inner air-passage wall, and at least one outlet vane disposed in the air outlet. The outlet vane is rotated about a rotation axis and deflects air blown from the air outlet at an angle of rotation. While the indoor unit is in an operating state, the outer air-passage wall and the outlet vane define therebetween an outer air passage through which the blown air passes, and the inner air-passage wall and the outlet vane define therebetween an inner air passage through which the blown air passes. The outlet vane is rotatable to an upward position at which the outer air passage between the outer air-passage wall and the outlet vane is narrowed to have a higher air flow resistance than the inner air passage.

主权项

1. An indoor unit comprising:
at least one air outlet having formed therein an inner air-passage wall and an outer air-passage wall located at outside of the inner air-passage wall, the outer air-passage wall being between an installation surface of the indoor unit and the inner air-passage wall; and at least one air flow direction louver disposed in the air outlet, the air flow direction louver being rotatable about a rotation axis and configured to deflect air blown from the air outlet by an angular position thereof in rotation, wherein while the indoor unit is in an operating state, the outer air-passage wall and the air flow direction louver define therebetween an outer air passage through which the blown air passes, and the inner air-passage wall and the air flow direction louver define therebetween an inner air passage through which the blown air passes, and the air flow direction louver is rotatable to an upward position, being the angular position, at which
the outer air passage between the outer air-passage wall and the air flow direction louver andthe inner air passage between the inner air-passage wall and the air flow direction louverare narrowed, and the outer air-passage has a higher air flow resistance than the inner air passage.
