PURPOSE: An automatic exhaust device of a double outer cover curtain wall is provided to discharge outer air flowing from the lower part of an outer curtain wall to the upper part and to be easily opened with simple switch operation. CONSTITUTION: An automatic exhaust device of a double outer cover curtain wall comprises a casing, an opening plate(220), a shaft rod, a link unit, a driving unit(300), and a control unit. The opening plate is installed in the inside of the casing and opens an outlet hole. The link unit is connected to the shaft rod, and an interlock link and a rotation link are folded in order to push and pull the shaft rod. When a switch connected to the control unit is pushed, the driving unit pulls or pushes up an operation rod(250). The link unit is folded by the operation rod and moves the shaft rod. The opening plate is rotated so that the outlet hole is opened or is closed. |
