DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as examples. FIG. 1 is a cross-sectional view of an air conditioner according to the present invention, FIG. 2 is an exploded perspective view of the air conditioner according to the present invention, and FIG. Is an exploded perspective view, (B)
Is a perspective view.

As shown in the figure, a main body case A of an air conditioner according to the present invention includes a base 1 having an open front surface, a suction port 2 on an upper surface portion, and an upper portion attached to an upper front side of the base 1. A panel 3 and a blow-out port 4 on a bottom surface curved so as to rise upward from the rear side to the front side.
And a lower panel 5 joined to the upper panel 3 so that the height dimension is equal to the depth dimension or the height dimension is slightly thinner than the depth dimension.

An air passage connecting the suction port 2 and the air outlet 4 has a heat exchanger 7 provided with a drain pan 6 at a lower portion thereof.
A blower fan 8 is provided, and the condensed water dropped from the heat exchanger 7 is received by the drain pan 6. Then, the suction air sucked from the suction port 2 is subjected to heat exchange by the heat exchanger 7 and is blown out from the blowout port 4 to the room to be air-conditioned by the blower fan 8.

An electrical component box 9 is provided on one side of the base 1 adjacent to the rear of one side of the drain pan 6. Drain water in the drain pan 6 is filled with a drain hose 10.
Is discharged by a drain pump 11 provided with

[0013] The drain pump 11 is
It is mounted so that the space inside the drain pan 6 can be used effectively and the drain water accumulated in the drain pan 6 can be forcibly discharged with sufficient mounting strength.

That is, FIG. 2, FIG. 3A and FIG.
