<p>A submergence-detecting power-window apparatus comprises: a window-opening-and-closing motor; a motor-driving unit for selectively driving the window-opening-and-closing motor; a switch control unit provided with control switches and used for supplying a control voltage to the motor-driving unit; a window-opening-and-closing switch; a control unit for turning on one of the control switches corresponding to an operation carried out on the window-opening-and-closing switch; a submergence-detecting circuit including a submergence-detecting sensor; and a submergence-time window-opening switch, wherein when an operation is carried out on the window-opening-and-closing switch with the submergence-detecting circuit put in an inoperative state, the control unit turns on one of the control switches corresponding to the operation carried out on the window-opening-and-closing switch, the switch control unit applies a control voltage to the motor-driving unit through the turned-on control switch to drive the window-opening-and-closing motor in order to open or close the window; and with the submergence-detecting circuit put in an operative state by the car' s submergence detected by the submergence-detecting sensor, a turned-on state of any one of the control switches is made ineffective and an operation carried out on the submergence-time window-opening switch causes a control voltage to be supplied to the motor-driving unit to drive the window-opening-and-closing motor in order to open the window. <IMAGE></p> |
