An upper suction port 9 is integrally formed in a grill shape on the upper portion 1A of the main body 1, and a suction grill 11 has an upper end 11A on a front edge portion 1B of the upper portion 1A. The lower end 11B is attached so as to be freely opened from the front surface of the air conditioner main body 1 in a state of being hinge-connected with respect to the center.

Inside the suction grill 11, a suction filter 13 having a filter material is attached so as to be vertically movable.

An air outlet 21 surrounded by a scroll portion 17 and a tongue portion 19 is formed in the lower portion of the air conditioner body 1, and an air direction changing plate 23 is arranged in the air outlet 21. There is. The wind direction changing plate 23 is a narrow lower horizontal plate 24 extending in the lower longitudinal direction of the air outlet 21.
And an upper horizontal plate 25 extending in the upper longitudinal direction of the air outlet 21 and a plurality of left and right flaps 26 extending in the shorter direction of the air outlet 21. An ion generator 27 is attached to the most narrow upstream position in the air outlet 21.

As shown in FIG. 2, the lower horizontal plate 24 is composed of a single narrow and narrow flap 24.
5 is composed of two flaps 25A, 25B which are wider than the lower horizontal plate 24 and are divided in the longitudinal direction.

Each flap 24, 25A, 25B
Are connected to independent DC stepping motors, and for example, as shown in FIG. 3, each of them is configured to be capable of swing control up and down independently with their phases shifted.

As shown in FIG. 4, a plurality of left and right flaps 26 are rotatably mounted on a single elongated plate 34, and the left and right flaps 26 are connected to each other by respective bars 32. Then, of the left and right flaps 26 connected to each other, the right and left flaps 26A at the right end in the figure
Is connected to the drive shaft of a DC stepping motor (not shown), and the left and right flaps 26 are synchronously controlled in posture by the forward and reverse rotations of the motor.

By the way, as shown in FIG. 5, the air conditioner main body 1 is installed in the substantially center of the conditioned room 41 (air conditioner main body 1X) or on the right side in the conditioned room 41. (Air conditioner body 1Y), installed on the left side in the conditioned room 41 (air conditioner body 1Y)
Z), and where in the conditioned room 41 to be installed changes depending on the conditions at the time of installation.

In this embodiment, no matter where the air conditioner body 1 is installed in the conditioned chamber 41, such as in the center, on the right side, or on the left side, the air flow Y blown out from the air outlet 21.
However, the postures of the left and right flaps 26 are controlled in synchronization so that the left and right flaps 26 reach the inside of the conditioned room 41 evenly.

FIG. 6 shows a control flow.

First, it is determined whether it is a cooling operation or a heating operation (S1). During the cooling operation, as shown in FIG. 7, the swing width W0 of the left and right flaps is the swing width W1 during the heating operation.
Correction control is performed narrower than that (S2). However, the swing width W0 during the cooling operation varies depending on the model of the air conditioner.

Regardless of the swing widths W0 and W1, as shown in FIG. 8A, the swing width of the left and right flaps is divided into four equal parts, and the first swing is equally distributed from the center of the air outlet 21 to the left and right. Five blowing positions C to C are set within the width W1 (during heating operation) (S3).

The five blowing positions C to C indicate the directions of the air flow. For example, in the position C,
The postures of all the left and right flaps 26 are controlled in synchronization with each other in a direction substantially parallel to the direction indicated by C.

Next, it is determined whether the automatic mode or the swing mode is set (S4).
The swing mode is a mode in which all the left and right flaps 26 are synchronized and always swings in the horizontal direction without stopping. The automatic mode is a mode in which the swing is performed in the horizontal direction, but depending on the conditions on the air conditioner side. Is a mode that also includes a stop operation.

When the automatic or swing mode is set in S4, the installation position of the air conditioner body 1 is determined (S5).

This installation position is as shown in FIG.
The determination is made by distinguishing between the center of the conditioned room 41, the right side, and the left side.

For example, an installation switch (not shown) such as a DIP switch which is switched according to the installation position is installed in the air conditioner main body 1, and an installation contractor or the like installs the air conditioner main body 1 in accordance with the installation position. ,
When the installation switch is switched, an installation position signal is output from this signal, and this signal is used to determine whether the room to be conditioned 41 is at the approximate center, right side, or left side.

When the installation position of the air conditioner main body 1 is substantially in the center of the conditioned room 41, the respective positions shown in FIG. 8A are not corrected (S6), and the five blowout positions C to C initially determined are set. It is used as it is, and the control according to this position is executed (S7). In S4, if the mode is not the automatic mode or the swing mode, it is a manual mode, and in this case also, the correction of each position shown in FIG. Then, the control according to this position is executed (S7).

According to this, within the first swing width W1 (during the heating operation) shown in FIG. 8A, which is evenly distributed from the center of the air outlet 21, all the left and right flaps 26.
Because the air conditioner is swung, the conditioned air can reach the inside of the conditioned room 41 evenly.

When the installation position is on the right side of the conditioned room 41, each position is corrected as shown in FIG. 8B (S8).

That is, the second swing width W2 on the right side of the first swing width W1 is masked and excluded, and the remaining third swing width W3 is divided into four equal parts, and the third swing width W3 is divided into four parts. , 5 new blowing positions RR
Is set, and control according to this position is executed (S9). The second swing width W2 is approximately 1/4 of the first swing width W1.

According to this, within the third swing width W3,
Since all the left and right flaps 26 are swung, the conditioned air is not supplied to the masked second swing width W2 but is supplied to the left of the conditioned room 41, so that the conditioned air is supplied to the conditioned room 41. It is possible to reach every corner evenly. Masked second swing width W2
Is too large or too small, unevenness occurs in the blowing of the conditioned air. Here, since the second swing width W2 is set to a width of about ¼ of the first swing width W1, it is possible to blow air evenly.

When the installation position is on the left side of the conditioned room 41, as shown in FIG. 8C, each position is corrected (S10).

That is, the left fifth swing width W4 in the first swing width W1 is masked, and the remaining fifth swing width W5, which is excluded from the mask, is divided into four equal parts and is included in the fifth swing width W5. , 5 new blowing positions LL
Is set, and control according to this position is executed (S11). The fourth swing width W4 is approximately 1/4 of the first swing width W1.

According to this, within the fifth swing width W5,
Since all the left and right flaps 26 are swung, the conditioned air is not supplied to the masked fourth swing width W4 but is supplied to the right of the conditioned room 41, so that the conditioned air is supplied to the conditioned room 41. It is possible to reach every corner evenly. Masked fourth swing width W4
Is too large or too small, unevenness occurs in the blowing of the conditioned air. Here, since the fourth swing width W4 is set to a width that is approximately ¼ of the first swing width W1, it is possible to blow air evenly.
