PURPOSE:To automatically deflect the airflow in the oscillating manner by connecting the front and rear edges of one of the airflow deflecting plates to the air guide by a shape memory alloy and an auxiliary spring, said airflow deflecting plates being connected with each other by a connecting rod, and by comprising an air passage between the shape memory alloy and a room air circulation fan between the air guide and heat exchanger. CONSTITUTION:When the outer edge of the airflow deflecting plates 30, 30' is turned toward the adhering wall 25, the hot air having passed the heat exchanger 23 passes near the shape memoy alloy 27. Then, a contracting force is generated in the shape memory alloy 27 to cause the inner edge of the airflow deflecting plate 30 to turn toward the air guide 26. Since the airflow direction is deflected toward the adhering wall 25', and at the same time, part of the cold air from the room air circulation fan 24 is directed to the shape memory alloy 27 by the effect of the air guide plate 34, the temperature near the shape memory alloy 27 is rapidly decreased. As a result, the airflow deflecting plate 30 returns to its original position. Such a motion is automatically repeated thereafter. |
