Air flow direction changing device for air conditioning device

Abstract

An air flow direction changing device of an air conditioning device according to the present invention includes: a lateral louver which is rotatably provided on the front side of a blowout port of a cabinet; a control section which changes the blowout direction of air sent from a fan by rotatably driving and controlling the lateral louver in the front surface of the blowout port; and a straightening plate which is provided on the rear side of the lateral louver in the blowout port and straighten the air flow from the fan located on the rear side in the passageway, and is configured such that the control section improves the blowing performance by controlling the rotation attitude of the lateral louver in such a manner that, when the lateral louver is held in an upward blowout attitude, an air blowing guide passage longer than the depth length of the lateral louver itself is formed by cooperation of the upper surface of the lateral louver with the upper surface of the straightening plate.

1 . An air flow direction changing device of an air conditioning device, comprising: a blowout port which is formed in a front surface of an air passageway in a cabinet; a lateral louver which is rotatably provided on the front side of the blowout port; a control section which changes the blowout direction of air sent from a fan by rotatably driving and controlling the lateral louver in the front surface of the blowout port; and a straightening plate which is provided on the rear side of the lateral louver in the blowout port and straighten the air flow from the fan located on the rear side in the passageway,
 wherein the control section controls the rotation attitude of the lateral louver so that, when the lateral louver is held in an upward blowout attitude, an air blowing guide passage longer than the depth length of the lateral louver itself is formed by cooperation of the upper surface of the lateral louver with the upper surface of the straightening plate.   
     
     
         2 . The air flow direction changing device of an air conditioning device according to  claim 1 , wherein the lateral louver is configured by one lateral louver member, so as to be arranged to cover the front opening of the cabinet at the time when the lateral louver is held in a closed attitude, and is formed to have a curved surface shape corresponding to the curved surface shape of the front opening of the cabinet. 
     
     
         3 . The air flow direction changing device of an air conditioning device according to  claim 1 , wherein, when the lateral louver is held in the upward blowout attitude, the inner surface side of the lateral louver is formed in a recessed curved surface, and an air blowing guide passage longer than the depth length of the lateral louver itself is formed by cooperation of the inner surface side of the lateral louver with the straightening plate arranged on the rear side of the lateral louver. 
     
     
         4 . The air flow direction changing device of an air conditioning device according to  claim 1 , wherein a plurality of vertical louvers are arranged on the rear side of the lateral louver in a swingable manner so as to enable the direction of the air from the fan to be changed in the left and right direction.
