Abstract

Provided is an indoor unit for a ceiling-embedded or ceiling-suspended air conditioner, having improved degree of design freedom of a lower surface panel. The indoor unit (1) has the lower surface panel (5), a suction opening (6) provided in the lower surface panel (5), a movable panel (7) for closing the suction opening (6) when operation of the unit is stopped, and drive means (10). The drive means (10) moves or rotates the movable panel (7). In operation, the movable panel (7) is moved or rotated and retracted upward from the lower surface of the lower surface panel (5).

Description

technical field [0001] The invention relates to an indoor unit of a ceiling-embedded or ceiling-suspended air-conditioning device provided with an air suction port on the lower surface of the indoor unit. Background technique [0002] Generally, an indoor unit of an air conditioner installed on a ceiling has a lower panel constituting a lower surface of the indoor unit. A suction port for taking in air is provided on the lower panel, and a filter for dust removal is attached to the suction port (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 10-399468 However, the lower panel is a part that is easily seen by human eyes, and the appearance design of the lower panel is an important condition for users to select products. However, for manufacturers, it is necessary to design the lower panel without compromising the basic functions of the suction port and the filter, and the appearance design of the lower panel is...
