AIR OUTLET PORT STRUCTURE FOR REGULATING INDOOR AIR

PURPOSE: To provide an air outlet port case, capable of precluding the invasion of indoor dust through an opening and closing cover and utilizing it effectively as a part of a wall when the case is not used while capable of utilizing the opening and closing cover as the guide member of air when the case is used. CONSTITUTION: An air outlet port case 11 is buried into a wall and an opening and closing cover 12, covering the whole surface of the front surface, is arranged at the front opening of the air outlet port case 11 while the opening and closing cover 12 is supported by the air outlet port case 11 pivotally into fore-and-rear direction utilizing the upper and lower ends of the cover 12 as supporting points. The opening and closing cover 12 is attached so as to be changeable in the pivoting position between a closed position, whereat the cover 12 is flushed substantially with the wall surface and blockading the front opening of the case, and an opened position, whereat the other end of the opening and closing cover 12 is slanted forward by a given angle about the supporting point of one end, by a driving actuator in the outlet port case 11. The opening and closing cover 12 is opened upwardly upon sending out cold air while the same cover 12 is opened downward upon sending out warm-air whereby the conditioning of indoor air is improved efficiently.
