AIR CONDITIONER AND FAN ASSEMBLY THEREOF

摘要

An air-conditioner and a fan assembly of the same are provided to reinforce the intensity of a ventilation fan and a hub by making a lower end of the hub incline downward. A fan assembly of an air-conditioner comprises: a hub(161) in which the wider its diameter is the closer it goes to a lower end; a plurality of blades(162) arranged at the circumference of the hub; and a bell mouth(163) settled on an upper end of the blade. The top end thickness and the lower end thickness of the hub are different each other. The external diameter of the hub lower end is smaller than the inside diameter of the bell mouth. It is more than 90° that the angle of a tangent line passing the low end of the hub and a rotation center axis of the hub.
