Next, its operation will be described using FIGS. 3 to 11 . 3 to 11 are cross-sectional views showing the blowing operation of the air conditioner of this embodiment.

First, the operation up to horizontal blowing will be described. In this embodiment, the so-called horizontal blowing refers to sending the blown air to a remote place in the room, and is mainly used for blowing out cold air (cooling operation mode).

FIG. 3 shows the stopped state of the air conditioning device, and FIG. 6 shows the horizontal blowing state.

The horizontal blowing action starts from the state shown in FIG. 3 , passes through the state shown in FIG. 4 , the state shown in FIG. 5 , and reaches the state shown in FIG. 6 .

As shown in FIG. 3 , when the air conditioner is in a stopped state, the panel 20 , the wind direction changing blade 30 and the middle blade 40 are all in a closed state.

After the blowing direction mode is set to horizontal blowing (for example, cooling operation) and the operation of the air conditioner is started, as shown in FIG. In addition, the arm 31 is operated together with the panel drive mechanism 21 by the arm motor 34 , and the wind direction changing blade 30 is operated in a direction away from the air outlet 6 .

Then, as shown in FIG. 6 , by the operation of the middle blade driving mechanism 41 , the middle blade 40 moves to a position where the upper end thereof abuts or substantially abuts the panel 20 . On the other hand, the airflow direction changing blade 30 is rotated by the blade motor 35 , and the end of the airflow direction changing blade 30 on the main body side of the air conditioner 10 abuts or substantially abuts against the lower end of the downstream end 6 a of the air outlet 6 .

In the state shown in FIG. 6 , blowing is performed horizontally or obliquely upward.

The air blown out from the air outlet 6 is guided horizontally by the wind direction changing blade 30, and since the downstream side end of the wind direction changing blade 30 is bent upward so that the air does not flow obliquely downward, the air can be effectively sent to the air. to the far side of the room.

Therefore, the cold air that tends to stay below the room is sent horizontally or obliquely upward in the room, and the cooling operation can be performed efficiently without making the user feel the cold wind, so that the room can be efficiently cooled.

In addition, since the upper part of the air outlet 6, that is, the lower part of the panel 20 is closed by the middle vane 40, a part of the air blown out from the air outlet 6 can be prevented from being guided to the air inlet 5, and a short circuit can be eliminated.

In addition, the air sucked into the main body of the air conditioner 10 is introduced from the suction port 5 on the top of the main body of the air conditioner 10, and is drawn from the suction port 5 on the front of the main body through the space on the upper part and both sides of the panel 20. import.

The action of transitioning from the horizontal blowing state to the stop state starts from the horizontal blowing state shown in Figure 6, and reaches the stop state shown in Figure 3 through the state shown in Figure 5 and the state shown in Figure 4. Each operation is opposite to the operation for transitioning from the stop state to the horizontal blowing state, so description thereof will be omitted.

On the other hand, the arm portion 31 is further moved by the motor 34 for the arm portion, so that the wind direction changing blade 30 is moved to the position farthest from the air outlet 6, and at this position, the wind direction changing blade 30 is rotated by the blade motor 35, Thereby, the wind direction changing blade 30 is set in an oblique blowing direction. Middle blade driving mechanism 41 is motionless.

Then, as shown in FIG. 10 , the wind direction changing blade 30 is swung at a predetermined angle by the motor 35 for the blade, and blowing is performed in an oblique direction.

The air blown out from the air outlet 6 is guided in an oblique direction by the wind direction changing blade 30, and since the downstream side end of the wind direction changing blade 30 is bent downward, the air does not flow in the horizontal direction, thereby effectively blowing air to the human body. .

In addition, since the top of the air outlet 6, that is, the bottom of the panel 20 is not closed by the middle blade 40, the air sucked into the main body of the air conditioner 10 is not only from the upper part and both sides of the panel 20, but also passes through the lower space. It is introduced from the suction port 5 on the front of the main body. In addition, the air blown out from the air outlet 6 is guided obliquely downward by the wind direction changing blade 30, so even though the air inlet 5 is not closed by the middle blade 40, a part of the air blown out from the air outlet 6 is not introduced into the air inlet 5.
