When the operation of the air conditioner is started, the air sucked into the indoor unit body 1 from the suction port 4 passes through the indoor heat exchanger 9 to exchange heat with the refrigerant, and is cooled or heated.
The vertical louver 12 and the horizontal louvers 11a and 11b pass through the ventilation path 6 to regulate the orientation in the left-right and up-down directions. The guide plate 23 is retracted from the front of the air outlet 5, and the adjusted air is delivered from the air outlet 5 toward the substantially horizontal direction or the downward direction as shown by an arrow A1.

When the temperature sensor detects that the temperature difference between the room temperature and the set temperature is small, the blower fan 7 is adjusted to gradually reduce the blown air amount. Then, as shown in FIG. 28, the guide plate 23 rotates to block the front of the air outlet 5 and form an air outlet 5 ′ that opens upward.
As a result, the conditioned air flowing through the air passage 6 is guided by the guide plate 2
3 and is guided upward from the air outlet 5'as indicated by arrow A2. Therefore, the same effect as described above can be obtained.
