Description of the Related Art Conventionally, an air conditioner of this type constitutes an indoor unit cabinet by mounting a front panel on a rear plate body of the indoor unit. In this indoor unit cabinet, the indoor heat exchanger is housed in a state of being configured in an inverted V shape including a front indoor heat exchanger and a rear indoor heat exchanger.

ビネット内に吸い込まれて、熱交換されずにそのまま吹
出口から吹き出される空気をいわゆる生空気という。However, in such a conventional rear side drain pan, since the drain drain port is simply opened to the rear side of the rear plate body, the operation of the indoor fan causes the inside of the indoor unit cabinet to operate. When the inside of the fan casing has a negative pressure, the outside air is sucked into the fan casing through the drain drain port, and is blown out from the outlet port as it is without being heat-exchanged by the indoor heat exchanger. For this reason, the air-conditioning efficiency is reduced, and dew condensation may occur in the indoor unit cabinet. The air thus sucked into the indoor unit cabinet and directly blown out from the air outlet without heat exchange is called so-called raw air.

An object of the present invention is to provide an air conditioner capable of easily adjusting the size and the like of the drain drain opening according to the flow rate and the like.

ことができる。By the way, in order to increase the drain drainage flow rate, it is necessary to enlarge the drain drainage port 13,
In order to prevent the entry of raw air, it is necessary to make the drain drain port 13 small. Therefore, it is necessary to adjust the size of the drain drain port 13. In that case, according to the present embodiment, the drain port cover 15 provided with the drainage channel 16 having a required opening area may be simply replaced, and the drainage drain port 13 is formed as in the conventional example. The rear plate body 3 itself does not need to be replaced and can be adjusted very easily.
