The filtering member is integrally formed by a frame provided with an engagement that is engaged with the ventilating fan body and a filtering screen located within the frame. The ventilating fan according to the present invention has the advantages that the filtering member can be fixedly mounted to the ventilating fan body in a simple structure manner without using fasteners such as screws, so as to facilitate the operation and save the working time. Moreover, the filtering member is not blown off to fall off when the ventilating fan hood is removed. In addition, the mounting of the filtering member in a reverse order is eliminated.

Ventilating fan

Ventilation device is mounted on inner wall in wind tunnel communicating between indoor and outdoor sides, having a ventilation louver. The ventilation louver includes a louver frame and a movable louver. Horizontal distance from position of gravity center of the movable louver to the inner wall is greater than horizontal distance from the movable louver shaft to the inner wall. A lever is disposed at a lower part of the louver frame to move in a left-right direction along bottom end face of the lower part of the louver frame. A connection element is provided to connect the movable louver with the lever between the movable louver and the louver frame, which is configured to be a slidable structure in the up-down direction, and transform the movement in the left-right direction of the lever to opening and closing movement of the movable louver around the movable louver shaft.
