BLOWER UNIT FOR AIR CONDITIONER FOR IMPROVING BLOWING EFFICIENCY BY CHANGING SECTIONAL SHAPE OF BLOWING BLADE AXIALLY

摘要

PURPOSE: A blower unit is provided to increase the discharged amount of air while reducing a ventilation resistance of an air inlet and to minimize the flowing loss through a blowing blade face. CONSTITUTION: The sectional shape of a blowing blade(31) in a blowing fan is changed toward an axial direction. A maximum chamber value of the blowing blade is reduced from the upper part to the lower part. A cord length of the blowing blade is increased from the upper part to the lower part through the axial direction. An installation angle of the blowing blade is reduced from the upper part to the lower part through the axial direction. Thereby, the flowing in the upper part of the blowing fan is improved by reducing a ventilation resistance in an air inlet. Moreover, the airflow is increased by increasing an air speed under the blowing fan.
