<p>The present invention prevents corrosion to air conditioners caused by stagnant condensed water. The invention solves the defects of known room air conditioners through movement of a conveniently located manually operable lever which controls the placement of a piston in a cylinder located on the bottom of a fluid drain pan inside the outdoor portion of the air conditioner. The cylinder contains slots which, when the lever has so positioned the piston, may alternatively be opened or closed. When the slots in the cylinder are open, the stagnant water may drain from the fluid drain pan.</p> |
