Each of the four motors is adjacent to each other and drives two blades which are installed at different discharge ports.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. 1 is a plan view showing a ceiling panel in the air conditioner according to the present invention, Figure 2 is a cross-sectional view showing the configuration of the air conditioner according to the present invention.

As shown in Figure 1 and 2, the air conditioner according to the present invention, the lower portion of the main body 10 is embedded in the ceiling (1) and the ceiling panel coupled to the open lower portion of the main body 10 20 is provided.

      In the main body 10, a circulation fan 11 providing power for circulation of indoor air, a fan motor 12 for driving the circulation fan, and indoor air installed and sucked around the circulation fan 11. Heat exchanger 13 for cooling or heating the indoor air by heat exchange with is installed. The fan motor 12 is fixed to the center of the upper surface of the main body 10, the heat exchanger 13 is arranged in a structure surrounding the circumference of the circulation fan (11). In addition, the lower part of the heat exchanger 13 is provided with a condensate receiver 14 to collect and discharge the condensate generated during the heat exchange process.

      In the ceiling panel 20, a suction port 21 is formed at a central portion of the ceiling panel 20 so that indoor air can be sucked into the main body 10 by suction force generated by the circulation fan 11. The filter 22 for filtering foreign matter in the air sucked into the inside of the 10) is provided.

      Outside the inlet 21, that is, the outer portion of the ceiling panel 20, a plurality of outlets are formed so that the air heat-exchanged in the main body 10 can be discharged back to the interior. In this embodiment, four discharge ports 31, 32, 33, and 34 are arranged to discharge air in four different directions.

      Four discharge ports 31, 32, 33, 34 are provided with a blade 40 to adjust the direction of the discharge air. Particularly, in the present invention, the discharge ports 31, 32, 33, and 34 are rotated independently of each other and are separated from each other along the longitudinal direction of the discharge ports 31, 32, 33, and 34 so as to adjust the direction of the discharge air. Blades 41a, 42a, 43a, 44a and second blades 41b, 42b, 43b, 44b are provided, respectively. At this time, the pair of first blades 41a and the second blades 41b installed at one discharge port, for example, the discharge port 31, are rotated at different rotational speeds and angles without being influenced by each other. It is connected to different motors. The configuration for this is described in more detail as follows.

      3 is a perspective view schematically illustrating an extract of a first blade and a second blade installed in one of four discharge ports and a motor for driving the same; 3 illustrates the first blade 41a and the second blade 41b installed in the discharge port 31 for convenience. As shown in FIGS. 1 and 3, four motors 51, 52, 53, and 54 are installed between the four discharge ports 31, 32, 33, and 34 to drive the blades 40, respectively. Each of the four motors 51, 52, 53, and 54 are adjacent to each other and simultaneously drive two blades installed at different discharge ports. For example, the motor 51 drives the first blade 41a and the second blade 44b, and in a similar manner, the motor 52 drives the second blade 41b and the first blade 42a. . Then, as shown in FIG. 3, the first blade 41a and the second blade 41b installed in one discharge port 31 are driven by different motors 51 and 52, respectively.

      4 is a view for explaining the operation of the air conditioner according to the present invention. Hereinafter, the operation of the air conditioner according to the present invention will be described with reference to FIGS. 1 to 4.

When the circulation fan 11 is rotated by the fan motor 12, the indoor air is introduced into the main body 10 through the suction port 21 of the ceiling panel 20. The introduced indoor air is discharged in the radial direction of the circulation fan 11 and passes through the heat exchanger 13, whereby the air is cooled or heated. The air that has been heat-exchanged as described above is supplied to the room again through the discharge ports 31, 32, 33, and 34. At this time, the wind direction is controlled by the blades 40 installed at the discharge ports 31, 32, 33, and 34.

      In particular, in the present invention, the first blades 41a, 42a, 43a, 44a and the second blades 41b, 42b, 43b, 44b, which are driven by different motors, are installed in the discharge ports 31, 32, 33, 34, respectively. Therefore, the wind direction of the discharged air can be variously adjusted. That is, as shown in FIG. 4A, when the motors 51 and 52 are controlled to rotate while the first blade 41a and the second blade 41b have the same phase and speed, one of the conventional air conditioners is one. Air is discharged in the same direction from the discharge port 31 of. However, as shown in FIG. 4B, when the two motors 51 and 52 are rotated at different speeds, the first blade 41a and the second blade 41b discharge air in different directions, respectively. The airflow of air is irregularly formed, so the air diffuses more smoothly and mixes indoors. In addition, even when the two motors 51 and 52 rotate the first blade 41a and the second blade 42b at the same rotational speed as shown in FIG. Mixing of the discharged air is made more effective. In the above description, the first blade 41a and the second blade 41b installed in one discharge port 31 are described for convenience. However, the rotational speed and the rotational direction of the four motors 51, 52, 53, and 54 may be properly adjusted. By adjusting, the wind direction of the air discharged into the room according to each combination can be realized in various forms.

      As described above, the present invention has the effect of allowing the air having different directionality from one discharge port at the same time to be discharged at the same time to effectively diffuse and mix the air-conditioning airflow in the room.
