The fluid present in the outdoor unit 10, for example, the purified water of the heat exchanger 130, or water (rainwater, etc.) flowing from the outside can be positioned or stored in the base body 210. The fluid can be discharged to the lower side of the base 210 through the first drain hole 217 formed in the base body 210. Accordingly, the base body 210 or the base 200 may be referred to as a "drain pan ".

Meanwhile, the first seating part 215 is configured to protrude upward from the base body 210. Since the compressors 51 and 52, the oil separators 61 and 62 and the gas-liquid separator 80 are supported by the first seating part 215, the compressors 51 and 52, the oil separators 61 and 62, The lower part of the gas-liquid separator 80 is spaced upward from the base body 210.

The oil separators 61 and 62 and the gas-liquid separator 80 and the like are influenced by the fluid existing in the base body 210 and the like due to the structure of the first seat 215 I can not accept.

The rim portion 220 extends along the circumference of the base body 210 and is configured to be stepped upward from the base body 210. That is, the upper surface of the rim 220 is formed at a position higher than the upper surface of the base body 210.

A step portion 219 (see FIG. 5) defining a step is formed between the base body 210 and the rim portion 220. The rim portion 220 may be disposed at a position higher than the base body 210 by the step portion 219.

The rim 220 may extend a predetermined length from the step portion 219 to the outside of the base body 210.

The rim 220 is provided with a frame main body 221 located on the upper side of the base body 210 and a second seating part protruding upward from the rim main body 221 and on which the heat exchanger 130 is seated 225).

The fluid present in the outdoor unit 10, for example, the purified water of the heat exchanger 130, or water (rainwater or the like) flowing from the outside can be positioned or stored in the frame body 221. The lower part of the heat exchanger 130 is spaced upward from the rim body 221 so that the second seat part 225 is spaced upward from the rim body 221, 130 may not be affected by the fluid existing in the rim body 221 or the like.

The base 200 includes a plurality of drain holes 217, 222, 227, and 228. The plurality of drain holes 217 are formed with a first drain hole 217 formed in the base body 210 and a second drain hole 222 formed in the edge body 221, And third and fourth drain holes 227 and 228 formed in the seating part 225. [ The first to fourth drain holes 217, 222, 227 and 228 may be formed through the base body 210, the rim body 221 and the second seat 225,

A plurality of the first to fourth drain holes 217, 222, 227, and 228 may be provided, and a plurality of drain holes may be spaced apart from each other.

The third drain hole 227 and the fourth drain hole 228 are formed at the same height by the height difference between the base body 210, the rim body 221 and the second seating portion 225, The third drain hole 227 may be formed at a position higher than the second drain hole 222 and the second drain hole 222 may be formed at a position higher than the first drain hole 217.

That is, the direction in which the third drain hole 227 extends may be formed to cross the direction in which the heat exchange fin 133 extends.

The base 200, that is, the base body 210 and the rim 220 functions as a drain pan for draining the dewatered water and the like. A plurality of drain holes may be formed in the base 200 to improve the drainage function.

However, when too much drain holes are formed, particularly when the drain 220 is formed with too many drain holes, the area that can support the heat exchanger 130, that is, the heat exchange pins 133, The second seating portion 225 can be reduced in area and thus the stable support of the heat exchanger 130 is limited and the rigidity of the second seating portion 225 may be reduced .

Therefore, in this embodiment, the third drain hole 227 is formed in the extension of the heat exchange fin 133 so that the drainage can be easily performed while the area for supporting the heat exchanger 130 is maintained at a set area or more. In the direction perpendicular to the longitudinal direction.

The third drain hole 227 extends obliquely so that the outer circumferential length of the third drain hole 227 becomes longer so that the heat exchange fins 133 Can be increased.

Meanwhile, since the fourth drain hole 228 is formed on at least one side of the third drain hole 227, the drainage function can be further improved.

The blocking portion 250 defines a step between the rim body 221 and the second seating portion 225. In detail, the blocking portion 250 is configured to extend upward from the rim body 221 toward the second seating portion 225. The height of the cut-off portion 250 may be such that the fluid present in the rim body 221 may be blocked to prevent the fluid from flowing into the base body 210.

The step portion 219 forms a step between the base body 210 and the rim portion 220, specifically, a step between the base body 210 and the second seat portion 225. The blocking part 250 forms a step between the rim body 221 and the second seating part 225. The step portion 219 may be referred to as a "first step portion", and the blocking portion 250 may be referred to as a "second step portion".

The lower part of the heat exchanger 130 is placed in the second seating part 225 and is disposed at a position spaced upward from the second drain hole 222.

The blocking part 250 may be installed outside the second drain hole 222 and adjacent to the second drain hole 222. For example, the blocking portion 250 may be disposed to surround at least a portion of the second drain hole 222 at a predetermined distance from the second drain hole 222.

For example, the rim body 221 may include defrost water generated in the heat exchanger 130 or rainwater flowing into the outdoor unit 10. In addition, the fluid can be discharged downward through the second drain hole (222).

The fluid present in the rim body 221 is restricted from flowing into the base body 210 and can be guided by the second drain hole 222 .

The base body 210 has a set capability for draining. When the fluid of the rim body 221 flows into the base body 210, the fluid having the predetermined capacity or more can exist in the base body 210, so that drainage may not be performed smoothly . If the undisplaced fluid is still present in the base body 210, freezing may occur depending on the ambient environment.

The present embodiment can solve the above-mentioned problem by constituting the blocking portion 250 and allowing the fluid present in the rim body 221 to be drained smoothly through the second to fourth drain holes 222, 227 and 228 .
