Description

筐体１の下方に取り付けられたパネル２の中央部には、室内から空気を取り込むグリル２０１が配置されており、その上方に空気中の塵埃を取り除くためのフィルタ２０２が備え付けられている。また、グリル２０１の外周には、４つの細長い矩形開口部である吹出口２１１が形成されている。吹出口２１１からは、室内ユニット９０によって温度を調節された空気を室内に送り出される。それぞれの吹出口２１１には、空気の吹出方向を調整するためのルーバー２０３が設けられている。 A grill 201 for taking in air from the room is disposed at the center of the panel 2 attached to the lower side of the housing 1, and a filter 202 for removing dust in the air is provided above the grill 201. Further, on the outer periphery of the grill 201, four outlets 211 that are four elongated rectangular openings are formed. From the blower outlet 211, the air whose temperature is adjusted by the indoor unit 90 is sent out indoors. Each air outlet 211 is provided with a louver 203 for adjusting the air blowing direction.
