<p>In a ceiling-mounted indoor unit (13), a filter (41) is placed along the upper surface of a suction grill (29). The filter (41) is attached to a power transmission belt (58) and moves with the rotation of pulleys (56, 57). A rotating brush (51) is in contact with the filter (41). When the filter (41) moves, dust collected on the filter (41) is removed by the brush (51). A dust receiving container (60) is placed below the rotating brush (51), and the dust removed from the filter (41) collects in the container (60). The dust receiving container (60) is attached to the liftable suction grill (29). When the suction grill (29) is lowered, the dust receiving container (60) descends together with the suction grill (29).</p> |
