Abstract

PURPOSE:To prevent fall of air volume so that a diffusion air current may be converged in a main current at a time of the wind deflection by providing a movable rear guide driving together with a wind deflector at a point of the fixed rear guide. CONSTITUTION:A movable rear guide 6 which is interlocked with a joint bar 7 turns upward by turning of a wind deflection 5 to a horizontal direction at the time of air conditioning. The distance l up to a center 8 of a fan 1 becomes longer because the (d) portion of the movable guide 6 turns horizontally toward a diffusive direction. Therefore, the air current (b) flowing on the side of a fixed rear guide 2 is converged in a main current (a). On the other hand, the movable rear guide 6 interlocked with the joint bar 7 is put in rotation by making the wind deflector 5 turn toward a lower direction at the heating time. The distance l up to the center 8 of the fan 1 becomes shorter because the (d) portion of the movable rear guide 6 turns downward, and the width between the wind deflector 5 and the movable rear guide 6 is widened. Therefore, an angle of the downward wind direction can be fully utilized.
