VENTILATING FAN

摘要

A ventilating fan (10) comprises: a ventilating fan body disposed with fan blades, a motor, and a frame (100); a joint (200); and an electrical part box (300). Ventilating air outlets (110) comprises a top air outlet (111) disposed on the top of the frame of the ventilating fan and a side air outlet (112) disposed on the side of the frame of the ventilating fan, which are connected together. The joint (200) is disposed with a protruding structure (211) matching the ventilating air outlets (110). Therefore, the air volume is guaranteed; the height of the ventilating fan is reduced so that the ventilating fan can be mounted on different ceilings; and the installation of the joint is simplified, so the cost is saved.
