Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner in which a shape of tongue of a stabilizer opposing to an outer circumference of a cross-flow fan is improved so as to improve a flow rate characteristic of air as well as a noise characteristic. SOLUTION: This air conditioner is constructed such that an air passage connecting a suction port arranged at a front surface and/or an upper surface of a main body with an outlet port 5 arranged at a front surface lower segment is provided with a heat exchanger 3 and a cross-flow fan 4. A stabilizer is arranged in a continuous manner at the upper part of the air blowing casing constituting the outlet port. A rear part of the stabilizer is formed with a tongue segment 6 opposing against an outer circumference of the cross-flow fan 4. With such an arrangement as above, the tongue segment is spaced apart by a predetermined distance from the cross-flow fan 4 and formed in a substantial coaxial curved surface shape with the cross-flow fan 4 and at the same time the substantial curved surface shape is provided with a projection 6a extending in a lateral direction while being opposite against the cross-flow fan 4.
