The present invention relates to a dehumidification damper, more specifically, to remove the toxic gas or smoke generated in the fire of the building as well as to prevent the expansion of toxic gas or smoke in the fire zone through the air supply or exhaust wind. The present invention relates to an automated damper that can sense temperature in the event of a fire.

In general, dehumidification dampers are used as a dehumidification facility to minimize human injury by removing toxic gases or smoke generated in a fire at places such as emergency passages, stairs, and platforms of buildings.

These smoke dampers are connected to the building's air temperature, that is, the air supply duct or the exhaust duct, respectively, to smoothly remove the air, and the air supply duct supplies outside air to the room in case of fire to dilute smoke or toxic gas. In case of fire, indoor smoke or toxic gas is discharged to the outside of the building to remove it.

And the ventilation damper installed in the air supply duct or the exhaust duct to open and close at various angles of the blade to maintain a comfortable atmosphere of the room, as well as automatically open the blades in case of fire or smoke or toxic gas along the duct Ensure the supply or discharge is smooth.

An example of such a damping damper is described in the registered utility model No. 0312620, the damping damper according to this technology is a damper blade 200 is rotatably arranged in the damper housing 100, as shown in Figure 6 ), A driving unit 300 for opening or blocking the damper housing 100 while rotating the damper blades 200, a control unit 400 for controlling driving of the driving unit 300, and the control unit 400. Regardless of the sensing of the) characterized in that consisting of a blocking device 500 to automatically close the damper blades 200 according to the temperature.

In the conventional regeneration damper according to the above configuration, when a fire detects a temperature or smoke exceeding the allowable range by a sensor installed inside the building, a signal transmitted from the sensor is sent to the control unit so that the motor of the driving unit is controlled by the control unit. When driven, when the rotary rod connected to each gear connected to the motor rotates, at the same time the main link and the auxiliary link is rotated at a predetermined angle to open the damper blade, the fire is gradually enlarged to increase the room temperature to form the rotating rod When molten lead is melted between the fixing hole and the gear and the connection state is separated from the rotation shaft of the damper blade fixed to the fixing hole, the damper blade is blocked as the rotation shaft is freely rotated by the elastic force of the elastic member connected to the main link.

However, the conventional smoke control damper has a problem in that a malfunction occurs due to lead as the molten lead is melted between the fixing hole formed in the rotating rod and the gear in the fire to close the damper blade.

In addition, lead has a problem that adversely affects environmental pollution.

Therefore, the present invention is designed to solve the above problems, and by installing the sensing unit and the damper control unit in a place that does not affect the operation of the damper, it is possible to detect the temperature that can exhibit the optimum blocking effect without malfunction.
