In general, air conditioners can change a room into a pleasant condition by sucking air through an air intake port, changing the temperature, humidity, cleanliness or the like, and then discharging the air into the room through an air discharge port.
A heat exchanger where a refrigerant and air exchange heat, and a blower that sucks air and blows the air to be discharged outside through the heat exchanger may be installed in air conditioners.
Air conditioners can form various air flows in a room, depending on the shapes of the air intake port and the air discharge port or the direction of the number of the openings.
Recently, it is the tendency to discharge air through as large area as possible while exposing the air intake port and the air discharge port to the outside as less as possible for safety and quality enhancement.
It is an object of the present invention to provide an air conditioner that can widely disperse and discharge air and keep a discharge body clean.
The above objects of the present invention are achieved by the inventions defined in the claims.

Preferably, an air discharge port is arranged along the periphery of the opening to allow air to be discharged to the opening.
Further, the opening may be open at both front and rear of the air conditioner.
Furthermore, the discharge body may comprise a plurality of air intake ports which introduce heat exchanged air from the main body to the discharge body.
Moreover, the plurality of air intake ports may be an upper air intake port and a lower air intake port which are respectively formed at the upper and lower portions and of the discharge body.
An air guide flow path for supplying heat exchanged air to the plurality of air intake ports may be provided between the main body and the discharge body.
Preferably, the discharge body includes air guides formed at the plurality of intake ports, for guiding air to an air dispersion flow path inside the discharge body. Further, the air dispersion flow path may deliver air to the air discharge port. Furthermore, the air guides may have dispersion ribs for dispersing air.
Moreover, a line connecting the plurality of intake ports may form a rotational axis of the discharge body.
In addition, the air conditioner may further comprise a rotating mechanism that rotates the discharge body about its rotational axis.

The rotating mechanisms 260 and 262 may be installed at the discharge body housing 38. A plurality of rotating mechanisms 260 and 262 may rotate the discharge body 5. The rotating mechanisms 260 and 262 may include an upper rotating mechanism 260 that rotates the upper portion of the discharge body 5 and a lower rotating mechanism 262 that rotates the lower portion of the discharge body 5. The upper portion of the discharge body 5 may be rotated by the upper rotating mechanism 260. The lower portion of the discharge body 5 may be rotated by the lower rotating mechanism 262. Both of the upper and lower portions of the discharge body 5 may stably rotate.
The rotating mechanisms 260 and 262 may include a motor 264, a pinion 266 that is installed at the motor 264, and a rack 268 that is engaged with the pinion 266. The motor 264 may be installed at the discharge body housing 38. The rack 268 may be formed at the discharge body 5. The rack 268 may be rounded at the outer body 200. The rack 268 may be rounded on the outer circumferences of the air guides 206 and 208 of the outer body 200. The rack 268 of the upper rotating mechanism 260 may be formed on the outer circumference of the upper air guide 206 and the rack 268 of the lower rotating mechanism 262 may be formed on the outer circumference of the lower air guide 208.
The operation of the air conditioner having the configuration described above is described hereafter.
First, when the blower 10 is driven, the air in the room may sequentially pass through the air intake port 2 and the heat exchanger 8 and then blown to the discharge body housing 38 by the blower 10. The air blown to the discharge body housing 38 is sucked into the discharge body housing 38 through the intake port 30. Some of the air sucked in the discharge body housing 38 flows to the lower portion in the air dispersion flow path P2 through the lower air intake port 204 of the lower air guide 208 and the other is dispersed to the left and right of the air guide flow path P1 and then flows to the upper portion in the air dispersion flow path P2 through the upper air intake port 202 of the upper air guide 206.
The air flowing to the lower portion in the air dispersion flow path P2 passes through the lower portion of the air discharge port L while being dispersed left and right, while the air flowing to the upper portion in the air dispersion flow path P2 passes through the upper portion of the air discharge port L while being dispersed left and right. The air passing through the air discharge port L may be discharged forward through the space G.
Meanwhile, the rotating mechanism 260 and 262 may rotate the discharge body 5 to any one direction of the left and the right and then stop the discharge body 200. The rotating mechanism 260 and 262 may keep the discharge body 5 swinging to the left and right.
When the motors 264 of the rotating mechanisms 260 and 262 are driven, the pinion 266 is rotated, and the upper air guide 206 with the rack 268 and the lower air guide 208 with the rack 268 rotate together. When the upper air guide 206 and the lower air guide 208 rotate, the left outer body 214 and the right outer body 216 rotate with the upper air guide 206 and the lower air guide 208. Further, the front body 6 and the rear body 7 rotate with the outer body 200. In the discharge body 5, while the front body 6, the rear body 7, and the outer body 200 all rotate, the air is dispersed through the upper air intake port 202 formed at the upper air guide 206 and the lower air intake port 204 formed at the lower air guide 208, and then discharged to the opening G through the air discharge port L from the air dispersion flow path P2. The air discharged to the opening G is discharged in the direction that the opening G is arranged, through the discharge space.
Meanwhile, in the air conditioner, when the discharge body 5 is rotated by the rotating mechanism 260 and 262, the light emitting mechanism 112 may emit light and radiate the light forward from the discharge body 5 while rotating with the discharge body 5. That is, in the air conditioner, when the discharge body 5 generates three-dimensional airflow in the room, the light radiated on the discharge body 5 rotates with the discharge body 5 and the three-dimensional discharging of the discharge body 5 may be visualized by the light radiated on the discharge body 5.
FIG. 20 is a plan view showing when the discharge body shown in FIGS. 12 to 14 is rotated.
When the discharge body 5 rotates, the discharge body 5 may discharge air in the direction in which the front of the discharge space is arranged, while being rotatably supported by the discharge body housing 38.
FIG. 20A is a plan view showing when the front of the discharge space of the discharge body faces forward, in which the discharge body 5 may discharges air forward from the air conditioner.
FIG. 20B is a plan view showing when the front of the discharge space of the discharge body faces forward and right, in which the discharge body 5 may discharges air forward and right from the air conditioner.
FIG. 20C is a plan view showing when the front of the discharge space of the discharge body faces forward and left, in which the discharge body 5 may discharges air forward and left from the air conditioner.
The discharge body 5 may discharge the air discharged from the discharge body widely forward to the left and right from the discharge body housing 38, such that three-dimensional airflow may be generated in the room.
