ーとして動作する換気扇カバー。 The ventilation fan cover body 1 has side plates 2 on the left and right sides, and a movable plate 3 with an upper part 4 which acts as a cover and a fire damper, and a space between the plate 3 and the cover body 1 is provided. Connected by an arm 5 that is bent at the center, a closed shape 8 is formed between the bend at the center of the arm 5 and the cover body 1.
The shape memory alloy that has been memorized is always fixed in the open shape 7, and due to the property of the shape memory alloy returning to the memorized shape from 7 to 8 when the temperature rises when a fire occurs, the central bent part of the arm 5 The ventilation fan cover operates as a fire prevention damper by pulling up the plate 3 which has been closed by the magnet 6 and completely closing the plate 3.
