Abstract

PURPOSE: To guarantee a smooth flow of cold air and prevent dewing on a turning-up air rectifier plate, by holding the plate by supports so as not to warp downward due to the on weight when the plate rotates almost horizontally and making the supports rotatable to interlock with right and left air rectifier plates. CONSTITUTION: The indoor machine body of an airconditioner is provided with a heatexchanger for the sucked air from an air suction opening and a fan 4 sending out the heatexchanged air to a discharge opening 5. A plurality of synthetic resin support plates 8 are arranged at the discharge opening 5 to support a turning-up air rectifier plate so that the plate 7 arranged at the discharge opening does not warp downward due to the own weight when rotated almost horizontally. In these support plates 8, support shafts 9, 10 protruding at both upper and lower sides are rotatably pivotted in bearing holes 5a, 5b provided at both upper and lower parts of the discharge opening 5 and respective supports are connected to mutually interlock, to the right and left air rectifier plates 6 through connecting members 13.
