The detection unit 41 detects the presence or absence of a person, for example, in four front, rear, left, and right regions in FIG. 17, and it is assumed that the air conditioner main body 1 is located at the contact point of the four regions, that is, substantially at the center of the entire detection region. When it is detected that there is a person in one area at the beginning of operation, for example, the front left side of FIG. 17, the first vane 8
The wind direction is directed to the suction port 3 by a and 8b, and a short circuit in which a part of the blown wind is sucked from the suction port 3 is formed. This causes the temperature of the blowing air to rise rapidly,
The room warms up quickly. On the other hand, since the blowout temperature is higher than the set temperature at the beginning of the operation, the second vane 9
a and 9b direct the wind direction of the blowing air toward the person, and the left and right wind direction changing plates A31a and 31b, the left and right wind direction changing plates B32a and 32b.
Also turn the direction of the wind toward people. As a result, people inside the room feel warmer faster than they warm inside. In addition, when the temperature difference between the room temperature and the set temperature is small at the beginning of the operation, and it is sufficient that the wind direction is not directed to the suction port 3 by both of the first vanes, it is possible to reduce the temperature on the side far from the area where the person is 1 vane 8b
Only the first vane 8a on the side closer to the person

方を向く。In the beginning of the operation, when there are people in a plurality of areas, such as the front left side and the back right side in FIG. 17, and when the temperature difference between the room temperature and the set temperature is large, both the first vanes are sucked into the suction port. To the 3 side, the second vane 9a, the left and right wind direction changing plate A31a, the left and right wind direction changing plate B32a to the front left person, the second vane 9b, the left and right wind direction changing plate A31b, the left and right wind direction changing plate B32b on the far right side. You can turn it to someone. If the temperature difference between the room temperature and the set temperature is small and it is sufficient not to direct both the first vanes to the suction port 3, the area farther from the air conditioner body 1 or the one with a large number of people By directing the first vane closer to the area to the person, this area approaches the set temperature faster than other areas. Further, at the beginning of operation, when there are people in a plurality of areas, for example, the front left side and the back left side in FIG. 17, the left / right airflow direction changing plate A31
a and the left / right airflow direction changing plate B32a may be divided into front and rear regions, respectively. Thus, when it is not necessary for both of the first vanes to direct the wind toward the suction port 3 in the initial state of operation, the first vane farther from the area where the person is present faces the suction port 3. , The first vane closer to the person faces the person.

変更板Ｂが人のいない方へ向くよう動作させてもよい。In the steady operation state, the room temperature is appropriately raised and lowered across the set temperature as shown in FIG. 18a, and the room temperature is maintained by reciprocating within this temperature difference. Here, the blowout temperature is in the heating state in the solid line portion in FIG. 18b, which is higher than the set temperature, and in the blown state in the broken line portion, which is substantially equal to the room temperature. Therefore, the first vanes 8a and 8b operate in the same manner as at the beginning of the operation in this solid line portion, and in the broken line portion,
Direct the wind direction along the ceiling surface in the same way as in steady operation.
The vanes, the left / right airflow direction changing plate A, and the left / right airflow direction changing plate B operate so as to face the direction where there is no person. When the blowing temperature is low, the direction of the wind is not directed at the person, so the person does not feel chills and can always be in a comfortable state. In the state of the broken line, the blowing wind whose wind direction is determined by the first vane is affected by the left and right wind direction changing plate immediately after blowing,
In reality, the wind direction is slightly higher than parallel to the ceiling surface. In addition, since the blowout temperature is higher than the set temperature immediately after the end of the heating state, that is, immediately after the state of the solid line is changed to the state of the broken line until the room temperature falls to the set temperature, the broken line portion of FIG. As in 18c, the blowout temperature in the solid line portion is higher than the set temperature, and the blowout temperature in the broken line portion is lower than the set temperature. Therefore, FIG.
In the state of the solid line part of c, operate like the beginning of operation,
In the state of the broken line portion, the wind direction may be directed so that the first vane is along the ceiling surface, and the second vane, the left-right airflow direction changing plate A, and the left-right airflow direction changing plate B may be operated so as to face the direction where there is no person.

Here, the blowout temperature is in the heating state in the solid line portion in FIG. 18b, which is higher than the set temperature, and in the blown state in the broken line portion, which is substantially equal to the room temperature. Therefore, the vanes 8a, 8b on the suction port side operate in the same manner as at the beginning of the operation in this solid line portion, and in the broken line portion, they operate together with the left / right airflow direction changing plate A and the left / right airflow direction changing plate B so as to face the direction without a person. And the outer vane 9
By a and 9b, the wind is directed so that the blown wind is along the ceiling surface. With such an operation, the wind direction does not face the person when the blowing temperature is low, so that the person does not feel chills and can always be in a comfortable state. Further, in the state of the broken line portion, the blowing air whose wind direction is determined by the first vane as in the fifth embodiment is not affected by the left and right wind direction changing plates immediately after the blowing, so that the air circulation in the room is efficient. It is often done.
