Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) In FIGS. 1 to 5, a special tool 2 to be connected to the lower part of a bent heat exchanger 1 is provided, and the special tool 2 is connected to a copper tube 1c of the heat exchanger 1. It has a system mating portion 2a and a system stop side 2b that contacts the water receiving tray 3.

According to this embodiment, the heat exchanger does not rise from the water tray in any installed state, so that water leakage can be prevented.

(Embodiment 2) In addition, the system side 2b of the special tool 2
By providing the protruding portion 2c, the dew water attached to the special tool 2 itself can be reliably led to the water receiving tray 3.

(Embodiment 3) Further, by providing the inclined portion 2d in front of the special tool 2, it is possible to reliably guide the dew water attached to the special tool 2 itself to the water receiving tray 3.

(Embodiment 4) In addition, the inverted V
By providing the character-shaped inclined portion 2e, even the dew water attached to the special tool 2 itself can be surely guided to the water receiving tray 3.

(Embodiment 5) Further, by providing a cutout portion 2f on the front of the special tool 2, the dew condensation on the special tool 2 itself can be reduced.

[0020]

As is apparent from the above embodiment, the invention according to claim 1 is provided with a bent heat exchanger in the air conditioner body, and the heat exchanger exchanges heat with a copper tube through which a refrigerant flows. A water receiving tray for receiving moisture generated when heat is exchanged is provided at a lower portion of the heat exchanger; and a special tool connected to the heat exchanger is provided at a lower portion of the heat exchanger.
