Abstract

A ventilating fan comprises: a ventilating fan body (11) and a mask (19) mounted on the ventilating fan body. The ventilating fan body is formed of a ventilating fan frame, a fan motor, and a cylinder (12) that is integrally formed with the ventilating fan frame and connects the inside and the outside of a room to form an air path. Also provided is shutter (13) that opens or closes the air path. The shutter of the ventilating fan consists of multiple shutter plates, and an upper end of the shutter plate is provided with a fold-over structure that prevents rainwater from flowing in a direction to the room. This ventilating fan can effectively prevent rainwater from entering the room.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation fan. Background technique [0002] Such as Figure 1A with Figure 1B Shown is a known ventilation fan 1, which can be installed in a predetermined opening formed in a flat wall member or window glass, comprising: a ventilation fan main body 2 and a mask 3 installed on the above-mentioned ventilation fan main body 2, the ventilation fan main body 2 is composed of The ventilating fan frame, the fan motor, and the cylinder 4 which is integrally formed with the ventilating fan frame and communicates with the indoor and outdoor as an air passage are formed. The above-mentioned cylinder 4 is arranged on the outside of the outdoor. The blinds 5. [0003] Like the structure of the prior art mentioned above, since the cylinder 4 as the air path communicating with the indoor and outdoor is arranged on the outdoor side, when the fan motor of the ventilation fan main body 2 is running...
