Abstract

PURPOSE:To reduce the impact noise of a solenoid by providing a rectifier for rectifying an AC input voltage, a comparator for comparing a rectified voltage and means for varying the threshold voltage level of the comparator by sequentially measuring the voltage inputted to the comparator and using the threshold voltage at the time when the comparator becomes ON as the AC input voltage of the solenoid. CONSTITUTION:A solenoid driving device provided at a water exhaust valve or a water feed valve in a washing machine has a rectifier 1 for rectifying an AC input voltage, a DC stabilizer 2, a voltage comparator 3, microcomputer 4, a bidirectional 3-terminal controlled rectifier 5, a solenoid 6, and resistors R1-R4 for setting the threshold level of the comparator 3 connected to the output terminal of a computer 4. With this construction, the voltage of the rectifier is sequentially measured by the program of the computer 4, resistors R1-R4 are sequentially closed ON by the combination of binary number to vary the threshold voltage of the comparator 3, and the voltage level when the comparator 3 becomes ON is used as an AC input voltage for the solenoid 6.
