の熱交換作用を図３を参照して簡略に説明する。2. Description of the Related Art Generally, an air conditioner is a compressor, a condenser,
The room temperature is adjusted to an appropriate temperature through a refrigerant cycle composed of a capillary tube and an evaporator. During the circulation of the refrigerant cycle, the refrigerant exchanges heat with the air passing through the evaporator to cool the indoor air. The heat exchange between the room air and the refrigerant will be briefly described with reference to FIG.

いる。FIG. 3 is a sectional view showing an indoor unit of a general package type air conditioner in which an indoor unit and an outdoor unit are separated. As shown, the evaporator 1 is provided at the lower part of the cabinet 2 so as to be inclined forward and upward. The lower end of the evaporator 1 is supported on the rear side of the drain panel 3. A blower 4 is provided above the evaporator 1.

される。When the blower 4 is operated, the air in the room is sucked into the cabinet 2 through the suction port 2a on the lower side of the cabinet 2. The air sucked into the cabinet 2 passes through the evaporator 1, and in this process, exchanges heat with the low-temperature and low-pressure refrigerant passing through the evaporator 1. Therefore, the hot air sucked into the cabinet 2 is cooled cold, and the refrigerant is vaporized. The cooled air is discharged into the room through the discharge port 2b on the upper side of the cabinet 2.

And then flows downward by its own weight and accumulates in the drain panel 3. The water accumulated in the drain panel 3 is discharged to the outside through a drain pipe 5 connected to one side in front of the drain panel 3.

る問題点が発生する。However, since the suction negative pressure due to the operation of the blower 4 acts on the upper side of the drain panel 3, the pressure on the upper side of the drain panel 3 is lower than the atmospheric pressure. Therefore, if a part of the drain pipe 5 is bent upward, the water inside the drain panel 3 may not be correctly discharged and may accumulate. In this case, as shown in FIG. 4, the lower portion of the evaporator 1 is immersed in the water accumulated in the drain panel 3, and the performance of the evaporator 1 is degraded.

上端より低い。The drain portion 22 has a bottom surface formed to be lower than the lower end of the evaporator 11, and a drain hole 22 a communicating with the lower drain pipe 15 is formed on one side of the bottom surface.
The drain part 22 is formed lower than the support part 21. And the front wall 22b and both side walls 22c of the drain part 22 are
As shown in FIGS. 1 and 2, the upper end is lower than the upper end of the support claw 23.

排出させる。According to the present invention as described above, since the bottom of the drain portion is located below the lower end of the evaporator, the suction negative pressure of the blower is hardly applied to the drain portion.
Therefore, even if a part of the drainage pipe is bent upward, there is an advantage that the drainage is performed smoothly. Further, since the upper end of the side wall of the drain portion is formed lower than the upper end of the support portion, water overflowing from the drain portion is prevented from flowing into the support portion. Accordingly, there is an advantage that the lower part of the evaporator can be prevented from being immersed in water. On the other hand, the upper end of the side wall of the drain portion may be formed at the same height as the upper end of the support claw, and the notch portion may be formed on the side wall of the drain portion. This notch allows water overflowing from the drain to drain out before it flows into the support.
