摘要

Of four corner covers (40) in an indoor unit(10), a horizontal length of an outer surface in a second corner cover (41) is the same as a horizontal length of an outer surface in a first corner cover(41), a horizontal length of an outer surface in a third corner cover (43) and a horizontal length of an outer surface in a fourth corner cover (44) are the same and are smaller than the horizontal length of the outer surface of the first corner cover(41). Opening dimensions (LA, LB, LC, LD) of four air outlet ports (14) in a horizontal direction are the same.

主权项

1. An indoor unit, comprising:
a casing having a rectangular shape in bottom plan view, and having air outlet ports for blowing out air laterally that are provided respectively in four sides thereof, and having four corner covers demarcating the air outlet ports, wherein the lengths of the four sides of the casing are the same; and a heat exchanger disposed inside the casing, wherein the four corner covers include:
a first corner cover disposed in a corner section where a piping space for refrigerant piping connected to the heat exchanger is provided;a second corner cover positioned diagonally opposite the first corner cover;a third corner cover positioned adjacently to the first corner cover; anda fourth corner cover positioned diagonally opposite the third corner cover; a total length in a horizontal plane of an outer surface of the second corner cover is the same as a total length in the horizontal plane of an outer surface of the first corner cover; a total length in the horizontal plane of an outer surface in the third corner cover and a total length in the horizontal plane of an outer surface of the fourth corner cover are the same, and are smaller than the total length in the horizontal plane of the outer surface of the first corner cover; opening dimensions of the four air outlet ports in a horizontal direction which are defined by the corner covers which are positioned on both sides of the air outlet port are the same; and the outer surface of each of the first, second, third and fourth corner covers includes first and second side surfaces that extend in the horizontal plane toward respective ones of the adjacent corner covers, wherein a length in the horizontal plane of each of the first and second side surfaces is half of the total length in the horizontal plane of the outer surface of the respective corner cover.
