Next, the operation of the integrated air conditioner configured as described above will be explained.

11i1 Indoor air sucked in from the indoor side suction port 29 of the main body 21 passes through the front part of the heat exchanger 22 which functions as an evaporator, and then is blown indoors as cool air from the indoor side outlet 30 by the cross flow fan 23. be done.

On the other hand, the outside air taken in from the outdoor side suction port on the side surface of the main body 21 passes through the rear part of the heat exchanger 22 which functions as a condenser, and then is discharged outdoors from the outdoor side outlet 32 by the cross flow fan 23.

By the way, by arranging the heat exchanger 22 diagonally inside the main body 21 in such a way that the indoor side is higher and the outdoor side is lower, the front part of the heat exchanger 22 acts as an evaporator, and condensation occurs on the fin surface. The drain water can be dripped through the fins to the rear of the heat exchanger 22, which functions as a condenser. In this way, by dripping drain water into the heat exchanger 22, the condensation capacity can be increased. In addition, the condensed water generated in the U-bend etc. is the indoor space 2.
The water is received by the water tray 33 at the bottom of the container 6 and flows out of the room.

The first embodiment has been described above, and next the second embodiment shown in FIG. 7 will be described.

The water tray 33 used in the first embodiment described above has a length to receive the heat exchanger 22 in the indoor ventilation circuit, but the water tray 33 shown in FIG. The heat exchanger 22 has a length that extends from the indoor ventilation circuit to the outdoor ventilation circuit, and functions as a condenser by receiving condensed water generated at the U-bend etc. in the water tray 33. The U-pen at the rear can be cooled and flowed outside.

Effects of the Invention As described above, according to the present invention, there is no need to provide separate heat exchangers and cross-flow fans for the indoor side and outdoor side, and one heat exchanger and one cross-flow fan can provide the indoor and outdoor sides. The function can be performed on the outdoor side, thereby making it possible to provide an easy-to-assemble and inexpensive integrated air conditioner.

In addition, by arranging the heat exchanger diagonally on the main body, the heat exchanger can be installed by making maximum use of the limited space, and the heat exchanger can be tilted lower toward the outdoor side. By doing so, the drain water naturally flows toward the end of the heat exchanger facing the outdoor side, so that it drips into the heat exchanger that acts as a condenser, increasing the condensing capacity. Therefore, there is no need to sprinkle drain water onto the heat exchanger using a provera fan with a slinger ring, and there is also no abnormal noise generated when drain water is sprinkled on the heat exchanger. Furthermore, since the machined heat exchanger is fitted into the water tray and supported, the assembly work is simplified compared to the conventional case where the heat exchanger is fixed to the vessel with screws.
Cost reduction can be achieved.
