PROBLEM TO BE SOLVED: To improve efficiency and reduce pressure resistance of a front grill so as to reduce noise by forming a leading edge into almost an arc, maintaining a cross section width of a furring of the front grill, and decreasing the ratio of a center distance of the furring toward the direction of a suction port. SOLUTION: In an air conditioner having a front grill formed by a furring, an indoor unit of the air conditioner comprises a front grill 101 having a horizontal furring 102, a bell mouth 103, a fan 104, a heat exchanger 107 and the like. A distance between the furring 102 increases toward the center of a suction opening of the fan 104. It is desirable to arrange the ratio D/W of the maximum width D of the furring of the front grill to the center distance W of the furring to be approximately 0.1 to 0.2. According to this arrangement, pressure resistance is reduced, the air flow from an exhaust port is caused to be difficult to be sucked by the front grill, as a result of which, the noise level is reduced, and the efficiency of the air conditioner is improved. |
