摘要： A power-saving apparatus comprises: a heater; a control unit for detecting at least two power-saving commands, and for outputting a first power-saving control signal and a second power-saving control signal; a power supply unit for supplying rated voltages required for peripheral devices; a power switching circuit for cutting off all rated voltages supplied to the peripheral devices, including the heater but excluding the control unit, when the first power-saving control signal is generated, and for starting the supply of all rated voltages cut off when the second power-saving control signal is generated; and a quick start circuit for supplying, to the heater, a quick start voltage for a certain time period when the start control signal is generated. A power-saving method comprises performing a power-saving mode by cutting off the voltages supplied to the peripheral devices when the power-saving control signal or command is received, determining whether a recovery command is detected, and recovering to a normal mode when a recovery command is detected.
