BLOWOUT GRILLE, AND INDOOR UNIT OF AIR CONDITIONING DEVICE IN WHICH SAME IS USED

WIPO Patent Application WO/2021/033263

A1

A blowout opening in an indoor unit of an air conditioning device has a blowout panel as a frame provided to an opening formed in a casing of the indoor unit, and a plurality of blade members that change the direction in which air is blown out are positioned on the blowout panel. Individual blade members are joined to the blowout panel so as to be capable of turning about an extension-direction axial center via respective joining mechanisms. The joining mechanisms each comprise a columnar joining shaft part provided to one of the blowout panel and the blade member, and a cylindrical joining recess provided to the other of the blowout panel and the blade member. A groove in which part of the column is removed along the extension direction is formed in the joining shaft part, a cutout part in which part of the circumference of the joining recess is opened along the extension direction is formed in the joining recess, and the joining shaft part and the joining recess are joined by combining the groove and the cutout part. This makes it possible to easily assemble the blade members to be attached to the casing of the indoor unit without imparting elastic deformation, and to avoid damage when the blade members and the casing of the indoor unit are assembled.
