Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condensed water treatment apparatus for an integrated air conditioner.

[0002]

2. Description of the Related Art A conventional condensed water treatment apparatus for an integrated air conditioner of this type will be described with reference to the drawings.

FIG. 4 shows the configuration of a conventional condensed water treatment apparatus. As shown in the figure, reference numeral 21 is a propeller fan, and a slinger ring 22 is provided at the tip of the fan. Condensed water 24 accumulated on the substrate 23 is scraped up by the slinger ring 22 and scattered to the outdoor heat exchanger 25. Heat exchanger 25
It is evaporated and treated by the heat of.

Reference numeral 26 denotes a water splash prevention ring which is attached to the outdoor fan air guider 27 and is formed so as to surround the propeller fan 21 which is on the suction side from the outdoor fan air guider 27 in a cylindrical shape. When the amount of the condensed water 24 becomes large and cannot be treated by the slinger ring 22, the water level of the condensed water 24 rises, and the condensed water 24 scraped up by the fan tip of the propeller fan 21 comes from the suction opening 29 of the outer case 28. A water splash prevention ring is provided so as to prevent the water splashing out (for example, the actual flatbed 2-
6915).

[0005]

However, in the conventional structure as described above, the propeller fan 21 between the inner and outer partition plates 30 and the outdoor fan air guider 27 is surrounded by the cylindrical water splash prevention ring 26. Therefore, the material cost of the water splash prevention ring 26 is required, and the number of assembling steps is increased.
Furthermore, since the resistance of the air drawn into the propeller fan 21 increases and the air volume decreases, the outdoor heat exchanger must be upsized in order to improve the heat exchange capacity, and the material cost becomes high.
