Description

Air conditioner {AIR CONDITIONER}

The present disclosure relates to air conditioners, and more specifically, to air conditioners that generate condensate.

An air conditioner is a device that cools, heats, or purifies sucked indoor air and supplies it indoors.

An air conditioner is installed on a window and can suck in indoor air, exchange heat with it, supply it indoors, and suck in outdoor air, exchange heat with it, and then discharge it outdoors. In the case of such a window-type air conditioner, an indoor fan through which indoor air flows and an indoor heat exchanger are disposed on the indoor side of the case, and an outdoor fan through which outdoor air flows and an outdoor heat exchanger are disposed on the outdoor side of the case.

However, conventional air conditioners had a problem in that it was difficult to remove condensate generated in the heat exchanger. In particular, in the case of air conditioners installed in windows, there was a problem in that it was difficult to discharge condensate to the outside of the case because the case was located between the indoor space and the outdoor space. Accordingly, the condensate remaining inside the case reduced the performance of the air conditioner and caused a bad smell.

In addition, conventional air conditioners have a problem in that heat exchange performance deteriorates due to overheating of the condenser while operation continues. Conventional air conditioners had a problem in that they could not prevent a decrease in heat exchange performance due to the absence of a structure to lower the temperature of the overheated condenser.
