The front ends 42A are close to each other. Each of the movable panel 41 and the upper wind direction plate 42 is disposed at a position where the front upper opening 28 is closed by being rotated as described above. Similarly, by rotating each of the movable panel 41 and the lower wind direction plate 43, the back surface of the movable panel 41 and the front end 43A of the lower wind direction plate 43 are close to each other. Each of the movable panel 41 and the lower wind direction plate 43 is disposed at a position to close the front lower lower opening 29 by being rotated as described above.

(In the case of the air-conditioning operation or the air-sending operation) FIGS. 8 and 9 are a perspective view and a side view showing a state in which the air conditioner 100 is in a state in which the air-conditioning operation or the air-sending operation is being performed. Fig. 10 is a cross-sectional view showing a state in which the air conditioner 100 is in a state in which a cooling operation or a blowing operation is being performed, corresponding to Fig. 3.

As shown in FIG. 8 to FIG. 10, when the air conditioner 100 is switched to the air-cooling operation or the air blowing operation (that is, during the cooling operation or the air blowing operation), the movable panel 41 and the lower wind direction plate 43 are rotated downward. The rear surface of the movable panel 41 faces the front end 25B (FIG. 9) on the lower side of the side wall 25, the front end (not shown) on the lower side of the side wall 26 having the same configuration, and the lower wind direction plate 43 so that the front lower opening 29 is provided. (Fig. 10) is blocked.

On the other hand, the movable panel 41 is rotated to the lower side and the upper wind direction plate 42 is swung upward, and the front upper opening 28 of the opening 27 is opened. A front upper blowing portion 28H is formed between the upper end 41A of the movable panel 41 and the front end 42A of the upper wind direction plate 42 (upward in front of the casing 20). The details will be described later, and in this state, the following front lower blowing portion 29H (Figs. 13 and 14) is closed. In this state, a plurality of multi-wing telecentric fans 35 are rotated by the drive motor 34 (Fig. 5).

The air is taken into the inside of the casing 20 through the suction port 22H, the air filter 31, and the air cleaning filter 32. The air passes through the heat exchanger 38 and the opening (the front upper opening 28), and is adjusted in the wind direction by the wind direction adjusting portion 40 (here, the movable panel 41 and the upper wind direction plate 42), and is formed in the upper portion of the wind direction adjusting portion 40. The front upper upper blowing portion 28H is blown out of the machine (arrow DR10 shown in Fig. 9).

As shown in FIG. 11, the air blown from the front upper blowing portion 28H travels along the ceiling 11, and then moves downward along the side walls 14 to 16 opposed to the air conditioner 100. The air further travels back to the side of the air conditioner 100 along the floor surface 13. The air rises along the side wall 12 toward the suction port 22H provided at the lower surface 22 of the air conditioner 100. During the cooling operation, the entire room 10 is cooled by the flow of air as described above. In the air conditioner 100, the circulating airflow as described above can be formed in the room 10, and an efficient cold air (cold room) effect or a blowing effect can be obtained.

(When the heating operation is performed) FIGS. 12 and 13 are respectively a perspective view and a side view showing a state in which the air conditioner 100 is in a state in which the heating operation is being performed. Fig. 14 is a cross-sectional view showing a state in which the air conditioner 100 is in a state in which the air conditioner is being operated, corresponding to Fig. 3.

As shown in FIG. 12 to FIG. 14 , when the air conditioner 100 is switched to the heating operation state (that is, during the heating operation), the movable panel 41 and the upper wind direction plate 42 are rotated upward. The rear surface of the movable panel 41 is closer to the front end 25A (FIG. 13) on the upper side of the side wall 25, the front end (not shown) on the upper side of the side wall 26 having the same configuration, and the upper wind direction plate 42 so that the front upper opening 28 is provided. (Fig. 14) is blocked.

On the other hand, the movable panel 41 is swung upward and the lower wind direction plate 43 is rotated downward, and the front lower lower opening 29 of the opening 27 is opened. A front lower blowing portion 29H is formed between the lower end 41B of the movable panel 41 and the front end 43A of the lower wind direction plate 43 (below the front side of the casing 20). In this state, the above-described front upper blowing portion 28H (FIGS. 9 and 10) is closed. In this state, a plurality of multi-wing telecentric fans 35 are rotated by the drive motor 34 (Fig. 5).

The air is taken into the inside of the casing 20 through the suction port 22H, the air filter 31, and the air cleaning filter 32. The air passes through the heat exchanger 38 and the opening (the front lower opening 29), and is adjusted in the wind direction by the wind direction adjusting portion 40 (here, the movable panel 41 and the lower wind direction plate 43), and is formed in the lower portion of the wind direction adjusting portion 40. The front lower front blowing portion 29H is blown out of the machine (arrow DR20 shown in Fig. 13).

As shown in FIG. 15, the air blown out from the front lower blowing part 29H moves down along the side wall 12, and follows the floor surface 13. The air further moves up the side walls 14-16. The whole of the room 10 is warmed by the flow of air as described above. In the air conditioner 100, the airflow as described above can be formed in the room 10, and an efficient heating (warm room) effect can be obtained.

(Operation and Effect) According to the air conditioner 100, the suction port 22H is formed in the lower surface 22 of the casing 20, and the air taken in from the suction port 22H passes through the air filter 31 and the air cleaning filter 32. Therefore, it is possible to perform air conditioning with less energy consumption while always purifying the air. Further, the blower 33 realizes air blowing by arranging a plurality of multi-wing telecentric fans 35 arranged in the horizontal direction. Therefore, by reducing the depth dimension, it is possible to reduce the size compared to the prior art, and it is possible to reduce the pressure feeling and to reduce the restriction on the indoor environment or the appearance.

Further, in the air conditioner 100 of the present embodiment, the movable panel 41 is pivotally supported by the shaft support portion 41T at a substantially central position in the horizontal direction and the (vertical direction) of the casing 20. According to this configuration, the movable panel 41 can form the upper and lower split type air outlets in the upper side and the lower side of the front and rear sides of the casing 20, and can be constructed by, for example, not switching the vertical shaft or using a complicated structure such as a lock mechanism.
