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-described problem by constituting the cut-off portion 250 to allow the fluid present in the rim body 221 to be drained smoothly through the second drain hole 222.

The fluid introduced into the base body 310 is guided by the drain hole 340 of the base body 310 and can be easily discharged to the lower side of the base 300. That is, the inclined surface 321 can be understood as a configuration for guiding the flow of the fluid to the drain hole 340 of the base body 310.

The central portion 311 having the convex portion, the central portion 411 having the concave portion and the inclined surface 321 of the rim portion 320 described in each of the above embodiments are arranged such that the water existing in the outdoor unit flows into the drain hole Guide device "in that it is guided so as to be able to flow toward the " guide device ".
