Abstract

A ventilating fan including a ventilating fan body provided with a motor, a frame having ventilating air outlets, and fan blades, an adapter and an electric element box. The ventilating air outlets include a top air outlet provided on a top face of the frame of the ventilating fan and a side air outlet provided on a side face of the frame of the ventilating fan which are communicated with each other. The adapter is provided with a raised structure adapted to the ventilating air outlet. With this structure, the height of the ventilating fan is reduced while air volume is ensured, so that the ventilating fan is adapted to be mounted onto various ceilings, and the cost can be saved while mounting of the adapter is simplified.

First claim

What is claimed is:

1. A ventilating fan, comprising:
a ventilating fan body provided with a motor, a frame having ventilating air outlets and fan blades;
an adapter; and
an electric element box,
wherein the ventilating air outlets comprise a top air outlet provided on a top face of the frame of the ventilating fan and a side air outlet provided on a side face of the frame of the ventilating fan which are communicated with each other, and the adapter is provided with a raised structure adapted to the ventilating air outlets; and
wherein an engaging structure integrally formed with the frame and engaged with the adapter is provided at a side of the top air outlet closer to the electric element box, and the engaging structure is a bending piece provided at a side of the top air outlet closer to the electric element box and engaged with the adapter, and the upper end of the bending piece is provided with a first oblique face and the lower end of the bending piece is provided with a first vertical face perpendicular to the top face of the frame, and
wherein an upper portion of a fixing section of the adapter is provided at a ventilating air-passageway side of the raised structure thereof with a structure, the upper end of which is provided with a second oblique face and the lower end of which is provided with a second vertical face perpendicular to the top face of the frame, and the second oblique face and the second vertical face fit to the first oblique face and the first vertical face, respectively.

2. The ventilating fan according to claim 1 , wherein: the raised structure is formed by enclosing the top air outlet by the upper portion of the fixing section of the adapter and is gradually inclined upward, and the height of the raised structure is less than or equal to the height of the electric element box.

3. The ventilating fan according to claim 1 , wherein: the raised structure is made of resin material.

4. The ventilating fan according to claim 1 , wherein: the top face of the frame is provided with a reinforcement rib.

5. The ventilating fan according to claim 1 , wherein: the fixing section of the adapter has a shape adapted for mounting to the frame, and comprises a horizontal portion enclosing the periphery of the top air outlet and a vertical portion enclosing the periphery of the side air outlet, and the lower end of the vertical portion is provided with protrusion pieces which are inserted into a flange of the frame and the upper portion of the vertical portion is provided with a mounting portion configured to fix the fixing section of the adapter to the frame.
