PURPOSE:To secure a sufficient discharge port area without causing a defect in structural strength and to obtain an air conditioning machine equipped with a fan having highly static pressure and a large airflow capacity, by a method wherein a vane wheel and a motor are housed in a space surrounded by a top plate, a bottom plate, a heat exchanger, a stepped side plate having an air guider as a unitary structure and a fan cover covering the recessed portion of said side plate, and then the fan cover is detachably fastened to the top plate or to the side plate. CONSTITUTION:A space surrounded by a top plate 11, a bottom plate 12, a side plate 13 and a heat exchanger 4 houses a motor 6 and a vane wheel 15 therein. The side plate 13 integrally incorporated with an air guider 17 is fabricated in a step form and the recessed portion of the side plate is provided with a bell mouth. A fan cover 19 is detachably fastened to the side plate so as to cover the recessed portion thereof. A casing is constituted by the top plate, the bottom plate, the heat exchanger and the side plate with the air guider as the unitary structure, therefore, even if wide openings are provided on the fan cover 19, there is no possibility of causing a defect in structural strength. In addition, since the fan cover 19 is detachably fastened, the vane wheel can be easily cleaned and replaced. |
