And an opening is formed in the exterior design surface at a position facing the air outlet of the outlet grill, and the grill is provided at a position corresponding to the interval between the adjacent apertures. To do.
More specifically, it is characterized in that flanges or ribs that project toward the duct and are connected to the duct are formed at upper and lower edges of a portion of the opening of the grill mounting panel corresponding to the gap. Further, a flange or a rib is installed between the upper and lower edges of the portion of the opening of the grill mounting panel and the upper and lower edges of the grill. Further, the grill is a fixed type having a plurality of stages of fins, and the fins of the grill and the fins of the blowing grill are arranged at the same pitch.

The air from the duct is sent from the air outlet of the duct that is not closed by the constricted portion or the like to the plurality of blowing grilles through the opening of the grill mounting panel and is also sent into the space between the blowing grills. on the other hand,
Opening holes are formed in the exterior design surface at positions facing the air blowing ports of the blowing grille, and the grilles are provided at positions corresponding to the intervals between the opening holes. Therefore, the portion of the exterior design surface corresponding to the interval does not serve as a dead space and functions as a grill. As described above, the amount of air blown from the exterior design surface having a constant area can be increased. Since the grill is a fixed type integrally formed on the exterior design surface, the work of inserting the grill becomes unnecessary. Further, by making the pitches of the fins of the blowout grill and the grill of the exterior design surface constant, the both are unified, and the appearance aesthetics can be improved. Further, a flange or rib extending toward the duct side is formed on the grill mounting panel, and a flange or rib reaching the grill mounting panel is formed on the grill, or a flange or rib reaching the grill is formed on the grill mounting panel. By doing either of the above, the air introduced into the grill is directed, and scattering of blown air is prevented.
