An air discharge apparatus usable with an air conditioner includes a body formed with a suction opening and a discharge opening, a blowing fan arranged in the body to circulate air, and a partition to separate a suction path defined between the suction opening and the blowing fan from a discharge path defined between the blowing fan and the discharge opening. The partition has a vortex-restraint portion, which protrudes into the discharge path to occupy a portion of a bottom region of the cross sectional area of the discharge path, thereby serving to prevent generation of a vortex of air in the discharge path.
