Submergence-detecting power-window apparatus

A submergence-detecting power-window apparatus comprising:

• 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.
