Document Type and Number:
Japanese Patent JP3035934
Kind Code:
B2
Abstract:
PURPOSE:To suppress damage for cloth in a washing tank or the generation of an impact sound when restarting a dehydrating operation and to prevent the reliability of a change gear mechanism from being lowered by detecting the falling of an output signal from the ON/OFF detector of a power supply switch, inhibiting a driving signal to a motor and a drainage valve, outputting the driving signal to the drainage valve when the rising is detected with the output signal more than a prescribed value, and afterwards outputting the driving signal of the motor after the lapse of fixed time. CONSTITUTION:A microcomputer 12 detects the A point of the falling when the output signal of an ON/OFF detector 11 is lowered, turns OFF switching elements 13 and 15 and stops the drive of a drainage valve 8 and a motor 6. Next, when a power supply switch 9 is turned ON with a voltage more than a B point, the microcomputer 12 detects that the output signal reaches a C point as the start, and conducts the switching element 15 in order to return to a state before turning OFF the power supply switch 9, namely, in order to continue a dehydrating state. Then, the drainage valve 8 is driven. However, since the drainage valve 8 is geared motor type, time delay is generated until the operation is completely finished. The microcomputer 12 drives the motor 6 after the drainage valve 8 is completely operated, namely, after the lapse of the fixed time.
