Abstract
An air conditioner includes a case accommodating an evaporator having a core portion and a lower tan disposed at a bottom of the core portion. The case has a recess portion disposed at an upstream air side of the evaporator, and a covering wall is formed to extend upwardly from the bottom of the recess portion to cover only the lower tank at an immediately upstream air side. When air passes through the evaporator, alien substances contained in air collide with the evaporator and fall to be deposited in the recess portion. Therefore, the deposition of the alien substances do not directly adhere to the lower tank of the evaporator to prevent the evaporator from being corroded.
