In addition, the indoor air I sucked into the rear air inlet 102c is cooled by the refrigerant while passing through the second inclined portion 134c of the indoor heat exchanger 134.

The indoor air (I ′) cooled as described above is guided by the louver 123 and the vane 124 of the discharge grill 120 after passing through the blower fan 132 and opens the air outlet 122. It is discharged to the room through.

Meanwhile, during the cooling operation, moisture in the air is condensed on the surface of the indoor heat exchanger 134, and some of the condensed water flows down to the left and right drain portions 108 of the first drain portion 106, The rest flows down to the second drain portion 121.

The condensed water flowing down the left and right drain portions 108 of the first drain portion 106 is moved to the front and rear drain portions 109, and is moved back and forth by the inclined portion 109a while passing through the front and rear drain portions 109. It is collected to the right of the drain 109, and then flows downward along the third guide rib 166 and the heat exchanger support 170.

The condensed water flows down to the second drain portion 121, merges with the condensed water flowing down the second drain portion 121, and is drained out of the air conditioner through the drain hose 126.

Meanwhile, part of the condensed water dropped from the front and rear drain portions 109 flows along the third guide rib 166 and the first guide rib 164.

Condensed water flowing between the third guide rib 166 and the first guide rib 164 is blocked by the first guide rib 164 and does not flow to the left end of the heat exchanger supporter 105. It is blocked by the inclined portion 165a and the vertical portion 165b of the second guide rib 165 and does not flow toward the upper fastening member 161, but is blocked by the inclined portion 164a of the first guide rib 164. The first guide rib 164 and the third guide rib 166 pass through the lower end of the second drain portion 121 without passing through the lower fastening member 162.

The condensate drainage structure of the air conditioner according to the present invention configured as described above has a first drain portion for receiving and condensing the condensate flowed down from the indoor heat exchanger in the chassis, the condensate flowed down from the indoor heat exchanger in the lower front of the chassis A discharge grill having a second drain portion for receiving and draining is installed, and a guide rib for guiding condensate dropped from the first condensate drain portion to the second condensate drain portion is formed in a heat exchanger supporter for supporting an indoor heat exchanger. There is an advantage that can prevent condensate generated at the surface falling to the bottom of the indoor unit.
