<p>An apparatus for controlling ventilation of an exhaust duct and a method for displaying a state of charged voltage in the same are provided to detect a voltage state of a charging unit and display the result to the outside so that a user recognizes the voltage state. A motor(20) drives an interrupting plate opening and shutting a ventilation path in accordance with power supplied from a power supply unit(10). A charging unit(30) charges with power in case the motor is stopped after rotation, and supplies charged power to the motor if the power supplied to the motor is cut off. A control unit(50) detects a power supply state, detects a voltage state of the charging unit in case the charging unit charges with power or supplies power to the motor, and outputs a control signal in accordance with a result of detection. A display unit(60) displays the detected voltage state of the charging unit in accordance with the control signal outputted from the control unit.</p> |
