<p>In an indoor unit (13) installed on a ceiling, a filter (41) is arranged along an upper surface of a suction grille (28). The filter (41) is attached to a transfer belt (58), and moves as pulleys (56, 57) rotate. A rotating brush (51) is in contact with the filter (41). Dust trapped on the filter (41) is removed by the rotating brush (51) as the filter (41) moves. A dust container (60) is provided below the rotating brush (51), and the dust removed from the filter (41) accumulates in the dust container (60). The dust container (60) is attached to a suction grille (28) which can be lifted/lowered. When the suction grille (28) is lowered, the dust container (60) is lowered together with the suction grille (28).</p> |
