<P>PROBLEM TO BE SOLVED: To provide an elevator control device capable of preventing it from overheating, reducing the emergency stopping frequency of the elevator to a great extent, and enhancing the user's convenience strikingly while the amount of dust intruding into the control device and the power consumption of a motor-driven fan are minimized. <P>SOLUTION: The elevator control device 10 includes a temperature sensor 13 installed internally, which measures the inside temperature of the control device 10, and on the basis of the measuring result, a main control unit 14 turns the fan 15 into Weak, Middle, or Strong so that the inside temperature of the control device 10 is optimized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
