Abstract

An indoor unit for an air conditioner, in which a gap at a joint between a panel and a body is set small, so that aesthetic design of the indoor unit is not impaired. In the indoor unit (1) of a ceiling mounting air conditioner, an indoor air suction opening (21) is located at a decorative panel (2b) forming the lower surface of the body (2). The indoor unit (1) has a flat panel (3) and a panel drive section (7). The flat panel (3) can take a closed position for closing the suction opening (21) and an open position for opening the suction opening (21) by tilting relative to the closed position. When the flat panel (3) moves from the closed position to the open position, the panel drive part (7) operates the flat panel (3) so that the flat panel (3) pivots about a predetermined pivot point(P3) after descending to a predetermined position.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of a ceiling-mounted air conditioner in which a suction port for indoor air is located on a lower surface of a main body. Background technique [0002] Conventionally, as an indoor unit of an air conditioner installed on a ceiling, for example, as disclosed in Patent Document 1, an indoor unit having an air outlet on the lower surface of a main body is widely known. In the indoor unit of Patent Document 1, a horizontal damper for changing the airflow direction of the air blown out from the air outlet is provided in the vicinity of the air outlet. Furthermore, in this indoor unit, the horizontal damper is rotated around two different points so as to extend the reach distance of blown air from the air outlet, thereby ensuring a sufficient volume of air blown out in the horizontal direction.
