In the air conditioner according to the present embodiment, during the cooling operation, the left motor 76 'is driven to rotate the left blower fan 74, and the left wind direction regulating motor 38' is driven forward and backward. Rotate the wind direction control member 36 'between the fully open position and the minimum open position, and the right wind direction control motor 48' is driven to move the right wind direction control member 46 'to the fully open position and then stop. Let's do it.

The indoor air A gathers to the right side of the air conditioner by the negative pressure formed by the rotation of the left blower fan 74 'and passes through the right side combined air inlet 4' and passes through the main chassis 12. And between the front panel assembly 20.

The sucked air (A) is deprived of heat by the refrigerant passing through the heat exchanger (18) while passing between the main chassis (12 ') and the front panel assembly (20), and then cooled to the left blower (74'). Passed through and blown to the left.

The cold air A 'blown to the left is controlled by the left wind direction adjusting member 36 while passing through the left side combined air inlet 2', and as shown in FIG. Discharged to the front left.

The cold air A ′ discharged to the front left side of the air conditioner spreads widely to the left side of the room, and first cools the left side of the room based on the air conditioner, and then diffuses to the right side of the room to the right of the air conditioner. And then continue cooling / cooling the left side of the room more strongly than the right side.

On the other hand, during the heating operation of the air conditioner, the right motor 86 'is driven to rotate the right blowing fan 84', and the right wind direction regulating motor 48 'is driven forward and backward. The right wind direction control member 46 'is rotated between the fully open position and the minimum open position, and the left wind direction control motor 38' moves the left wind direction control member 36 'to the fully open position and then stops. .
