The condensed water collected into the guide passage 132 is collected by the water collecting unit 136 and then forced upward by the condensate pump 372. The condensed water forced upward by the condensate pump 372 is a guide hose. Guided by 374 is introduced into the first collecting space 152.

While repeating this process, the outdoor heat exchanger 320 is water-cooled with cold condensed water generated from the outer surface of the indoor heat exchanger 210.

In addition, even if the condensate pump 372 sends a large amount of condensed water to the first catchment space 152 by using the air conditioner 100 for a long time, the catch tank ( Since the water is collected at 350, condensate is prevented from overflowing the water collecting unit 136.

While the condensate flow means 370 is operating, the steam generating means 400 is also operated to cool the outdoor heat exchanger 320. That is, as illustrated in FIG. 7, the steam generating means 400 flows along the outdoor heat exchanger 320 to generate ultrasonic waves when the condensed water collected in the guide passage 132 flows into the mounting space 139. Phase changes to water vapor.

At this time, the condensed water evaporated by the steam generating means 400 is located in the right space of the outdoor heat exchanger 320, the outdoor air blower 330 is generated outdoors by the air flow (from right to left) It is mixed with air to absorb heat by contacting the outer surface of the outdoor heat exchanger (320).

Subsequently, gaseous condensate that absorbs heat of the outdoor heat exchanger 320 is guided by the outdoor orifice 336 through the outdoor air flow hole 338 ′ to the outside through the outdoor air outlet 124. Discharged.

By the above process, the outdoor heat exchanger 320 may be further cooled by the condensate flow means 370 and the steam generating means 400.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the air conditioner according to the present invention as described in detail above, the steam generating means for evaporating the condensed water collected on the upper surface of the base to cool the outdoor heat exchanger.

Therefore, the temperature reduction amount of the outdoor heat exchanger is significantly increased, thereby improving the heat exchange efficiency of the air conditioner.

In addition, the condensed water in the steam state that absorbs the heat of the steam generating means is discharged to the outside to reduce the remaining amount of condensed water in the air conditioner has the advantage that the user does not have to empty the water collection frequently to improve the ease of use.

In addition, there is an advantage that a safety accident such as an electric shock, which may occur due to the full amount of condensate, is prevented in advance.
