<p>PROBLEM TO BE SOLVED: To achieve a power source control device for a washing machine and the like which eliminates a power-on switch, turns on the power source by opening/closing of a door, reduces unnecessary power in a standby state without a door opening/closing, and enables a re-operation after recovery from power failure.SOLUTION: A power source control device includes: a control system power source 1 for supplying a voltage to a control circuit such as a microcomputer 11 and the like; a power system power source 2 for driving a power system load 23 such as a washing motor and the like by control of a power system power source relay 20; and a door SW6 for controlling the control system power source 1 interlocked with the opening/closing of the door. In the power source control device, the power system power source 2 starts up by a voltage being supplied to the control circuit from the control system power source 1 by the opening/closing operation of the door SW6, and by a contact point of the power system power source relay 20 being closed by a driving signal from the microcomputer 11. Unnecessary power is reduced in a standby state where there is no door opening/closing, and a re-operation after the recovery from power failure can be achieved.</p> |
