Document Type and Number:
Japanese Patent JP2506235
Kind Code:
B2
Abstract:
A power-off control circuit for a household appliance, including a manually operating momentary switch having conductive and non-conductive states. The switch is connected to a source of electric power so when the switch is momentarily manually operated into the conductive state, power flows into the power-off control circuit. There is a power regulator connected to the manually operating switch for receiving the power during the conductive state and for converting the received power into a voltage. A timer is connected to the power regulator and when activated, initiates a predetermined time period in which the household appliance operates. The circuit also includes a relay connected to the timer and the source of electrical power so as to be in parallel with the manually operating switch. The relay operates in a conductive and non-conductive state and is in the non-conductive state until receiving a signal from the timer at which time the relay changes to the conductive state. Now, the power regulator receives power through the relay until the relay changes to the non-conductive state and power is prevented from flowing through the power-off circuit.
