運転停止時は吹出口31と吹出用通路32は風向板5で覆われて視認されない。この時、化粧パネル3は明色に形成された吸込グリル40とコーナーパネル41とパネルカバー42と風向板5が視認されることで、全体に明色となり空調室Kの天井面T1に馴染んだ意匠となる。この様に本発明の明色とは空調室Kや天井面T1の色に馴染む白色に近い明るい色である。   When the operation is stopped, the outlet 31 and the outlet passage 32 are covered with the wind direction plate 5 and are not visually recognized. At this time, the decorative panel 3 is lightly colored as a whole by being visually recognized by the suction grill 40, the corner panel 41, the panel cover 42, and the wind direction plate 5 formed in a light color, and is adapted to the ceiling surface T1 of the air conditioning room K. Become a design. In this way, the light color of the present invention is a bright color close to white that is adapted to the colors of the air conditioning room K and the ceiling surface T1.

運転が開始されると風向板5が回動する。この時、吹出通路32は連続した暗色の溝として視認されることで、内部部品が目立たずに全方位吹出を印象づける意匠となる。この様に本発明の暗色とは上記の明色より暗い色である。さらに化粧パネル本体30をパネルカバー42とコーナーパネル41で覆うことで化粧パネル本体30の背面にリブを多く設けることができて化粧パネル本体30の剛性を上げることができるものとなる。   When the operation is started, the wind direction plate 5 rotates. At this time, the blowout passage 32 is visually recognized as a continuous dark groove, so that the internal parts become inconspicuous and the design impresses the omnidirectional blowout. Thus, the dark color of the present invention is a color darker than the light color. Further, by covering the decorative panel main body 30 with the panel cover 42 and the corner panel 41, many ribs can be provided on the back surface of the decorative panel main body 30, and the rigidity of the decorative panel main body 30 can be increased.
