In addition, the air discharged through the auxiliary discharge port 164 is discharged to the existing blind spot formed between the four directions. As such, the auxiliary discharge port 164 directly discharges air into a blind spot where air is not previously discharged, so that the air in the room is cooled or heated more quickly, thereby reaching a desired temperature more quickly. Therefore, it is possible to reduce the operating time of the air conditioner can reduce the energy loss by the air conditioner.

In addition, by forming the auxiliary discharge port 164, more flow rate than the existing discharge flow rate is discharged to the room to further increase the cooling and heating efficiency, thereby enabling the air conditioner to operate more efficiently.

Meanwhile, as illustrated in FIG. 8, the auxiliary discharge port 164 corresponding to the corner portion of the internal flow path 138 (see FIG. 4) blocked by the partition wall 136 is an extension rib of the drain pan 180. It communicates with the internal flow path 138 through the communication hole 188 formed in the (187), the air flow of the internal flow path 138 (see Fig. 4) through the communication hole (188) of the auxiliary discharge port (160) 164 is discharged. Therefore, while discharging airflow through the four auxiliary discharge ports 164, the noise generated from the coolant pipe 110 can be prevented from being transferred to the room, thereby further improving the reliability and productability of the product.

It is communicated by the connecting duct 388 formed on the upper surface of the.

Referring to FIG. 12, according to the fourth embodiment of the present invention, the auxiliary outlet 464 is connected to an adjacent main outlet 462. With this structure, the airflow discharged through the discharge ports 462 and 464 is discharged more uniformly in the room.

According to the present invention as described above, by forming the auxiliary discharge port in the corner portion of the front panel, the air flow passing through the heat exchanger is more uniformly discharged into the room, thereby improving the cooling and heating efficiency of the air conditioner.

In addition, the flow rate of the air discharged into the room by the auxiliary discharge port can be increased, thereby increasing the flow rate through the heat exchanger, thereby further improving the cooling and heating efficiency.

As such, by improving the cooling and heating efficiency of the air conditioner, it is possible to cool or heat the room in a short time, thereby reducing the operating time of the air conditioner, thereby reducing energy consumption of the air conditioner.

In addition, by blocking the corner portion and the room where the refrigerant pipe is noisy connected to the partition wall and the drain pan, it is possible to reduce the noise transmitted to the room.

As a result, according to the present invention it is possible to improve the reliability and product value of the product by improving the energy efficiency by improving the heating and cooling efficiency while maintaining the quiet of the room.
