Abstract

The invention discloses an automatic power-off energy-saving circuit comprising an external circuit. The external circuit comprises a single-chip microcomputer, a normally open all-pole-disconnectable power switch, a connector, a PCB, and a single-pole double-throw relay. Both the single-pole double-throw relay and the connector are disposed on the PCB. The normally open all-pole-disconnectable power switch is electrically connected with the connector. The single-pole double-throw relay is electrically connected. A power management module is disposed before all power-consuming electric parts (including a filter) and capable of controlling machine power. The normally open all-pole-disconnectable power switch is used to perform one action to trigger two independently-isolated circuits in the same time, namely a power interlocking circuit and a power switch detection circuit, so that machine cost and standby power consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of automatic power-off of household appliances and similar appliances, in particular to an automatic power-off energy-saving circuit. Background technique [0002] At present, household electrical appliances require users to cut off the power supply of the whole machine by pressing a power switch or unplugging the power supply, so as to realize the effect of power saving. However, most users forget to turn off the power supply, so that the home appliances or appliances themselves are always charged, wasting electric energy; and the European Union has also strengthened the supervision of energy consumption, taking into account the energy consumption in standby and shutdown states, and improving Energy consumption requirements for home appliances. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to overcome the above disadvantages, aimi...
