The present invention relates to a condensate drainage structure of an air conditioner, and more particularly, to a condensate drainage structure of an air conditioner capable of preventing condensate generated at the surface of an indoor heat exchanger from falling down to an indoor unit.

In general, the air conditioner is to create a more comfortable indoor environment by cooling / heating the room, and divided into two types (window type) and separate (seperate or split type).

The one-piece type and the separate type are functionally the same, but the one-piece type integrates the function of cooling heat dissipation, and is directly installed by drilling a hole in a wall of a house or by hanging a device on a window. The separate type installs a cooling device on the indoor side and heat dissipation on the outdoor side. And a compression device to connect the two devices separated from each other by a refrigerant pipe.

The separate type of the air conditioner is an indoor unit having an indoor heat exchanger to perform a cooling function largely, an outdoor heat exchanger performing a heat dissipation and compression function, an outdoor unit having a compressor and an expansion device, and an indoor unit and an outdoor unit connected to each other. It consists of refrigerant piping.
