トラブルが多く、コストが高くつく欠点があった。Conventionally, a looper (blade) that changes the blowing direction of air in an air conditioner up and down is a type that has a blade that is rotatable in the vertical direction at the outlet of a casing, and the angle of the blade can be changed manually or automatically. Some automatic systems use bellows to change the angle of the blow-off looper in response to changes in refrigerant gas pressure, but these have the disadvantage of being expensive and prone to problems such as gas leaks from the bellows.

。On the other hand, the blowing direction of the blowing air changes discontinuously into two stages, upward and downward, and the temporal change in the blowing direction is 0N.
-OFF In this so-called two-stage switching type device, which has a pulse wave-like characteristic, the upward blowing direction and the downward blowing direction are alternately repeated at regular intervals, and emphasis is placed on the near side where air conditioning is difficult to achieve with the downward blowing. At the same time, the upward airflow extends the reach of the airflow to provide cooling and heating over long distances.Furthermore, these airflows and convection also effectively cool and heat the middle area, thereby efficiently and uniformly heating and cooling the entire room. It produces the effect that it can.

できる。As explained above, according to the present invention, blades are provided at the outlet of the casing so as to be rotatable in the vertical direction, and the blades and the casing are formed by a driving member made of a shape memory alloy whose shape changes with temperature changes. An electric heater is connected to the drive member to heat the drive member, and the electric heater is alternately turned on or off at regular intervals to change the shape of the drive member and rotate the blades up and down, Since the blowing direction of the blown air is changed periodically in three directions, up and down, the upward blowing direction and the downward blowing direction are repeated alternately at fixed time intervals, and the downward blowing blows out the front of the room. While heating and cooling is focused on the sides, the upward airflow also cools and heats far parts of the room, and together with these airflows, the middle part of the room is also effectively cooled and heated by convection, thereby efficiently and evenly heating and cooling the entire room. be able to.
