<p>PURPOSE: An interlock type damper using the magnetism of a solenoid and a magnetic is provided to achieve airtightness by the magnetism, high-speed opening and shutting, and noise reduction by opening and closing of a control plate interlocking with the operation of a fan after installation of separated solenoid and magnetic inside the interlock type damper. CONSTITUTION: An interlock type damper comprises a housing(100), a controller, and a control plate. A projection is formed inside the housing. The projection prevents over-rotation and encourages a sealing by contacting with the outer periphery of the control plate. The control plate comprises upper and lower partitions divided based on a cross section. The upper and lower partitions are separated from each other. The leading edges of the inner part in the lower partition and the outer part in the upper partition based on the exhaustion direction of the air are placed on the same line as a hinge(350) and located close to the projection of the housing on the same line, thereby minimizing a gap.</p> |
