冷却能力が低下するという問題がある。2. Description of the Related Art An integrated air conditioner, as shown in FIG. 1, is provided with a partition plate 2 on a main body base 1 to divide it into an outdoor side and an indoor side, and an outdoor heat exchanger 3 on the outdoor side. , The slinger ring-equipped propeller fan 4 and the outdoor heat exchanger 3 and the slinger ring-equipped propeller fan 4 facing each other.
An air guide plate 5 having a bell mouth 6 surrounding the room is provided, an indoor heat exchanger 10 is provided on the indoor side, and an axial fan 11 is provided opposite to the indoor heat exchanger 10, and the indoor heat exchanger 10 is provided during cooling operation. The condensed water generated in 1 is guided to the outdoor-side base 1, and the condensed water is scraped up by the rotation of the propeller fan 4 with a slinger ring and splashed in the outdoor heat exchanger to improve the cooling effect. By the way, regarding the positional relationship between the propeller fan 4 and the bell mouth 6, it is desirable that the rear end of the propeller fan 4 is slightly projected from the suction side of the bell mouth 6 in order to maximize the air volume. Due to
The water droplets that have been scraped up by the rotation of the propeller fan 4 and that have adhered to the propeller fan 4 are generated by the centrifugal force.
Since it is blown in the rotational direction from the rear end and jumps out through the louver 13 of the outer case 12 as it is, a water shield plate 7 is provided on the baffle plate 5 to prevent water droplets from jumping out of the outer case. However, since the water shield plate 7 is located on the suction side of the bell mouth 6 as described above, the flow of wind sucked along the bell mouth 6 is blocked by the water shield plate 7 and the outdoor heat There is a problem that the cooling capacity of the exchanger 3 decreases.
