Abstract

The invention discloses an ultralow standby power consumption circuit of an electric appliance. The circuit comprises a monochromatic light sensing circuit, a signal conditioning circuit, a relay driving circuit and a magnetic latching relay, wherein the monochromatic light sensing circuit, the signal conditioning circuit, the relay driving circuit and the magnetic latching relay are connected insequence. The monochromatic light sensing circuit is used for receiving a remote control optical signal and generating a pulse signal under the action of a preset wavelength light. The signal conditioning circuit is used for amplifying the pulse signal. The relay driving circuit is used for controlling the electrification of the magnetic latching relay so as to drive the magnetic latching relay towork. The magnetic latching relay is connected with a remote control circuit of a controlled household electrical appliance and is used for controlling the on and off state of the circuit. The circuit further comprises a power supply circuit for supplying power. Through controlling the standby power supply of the electric appliance, the standby of the electric appliance is realized by the ultralow standby power consumption circuit. Therefore, the original standby power consumption of the electric appliance is saved, and the ultra-low power consumption standby is carried out.

Description

technical field [0001] The invention relates to an electric appliance circuit, in particular to an electric appliance ultra-low standby power consumption circuit. Background technique [0002] With the continuous improvement of people's quality of life and the continuous deepening of office automation and informatization, more and more home and office electrical equipment have remote control functions; while people enjoy the convenience brought by remote control technology, the The problem of standby power consumption of the remote control circuit is also placed in front of people. [0003] The standby power consumption of the remote control circuit (hereinafter referred to as the standby power consumption) refers to the energy consumed by the part of the appliance that still needs to keep working in order to realize the function of remote control at any time after the household appliance is turned off by the remote control. In the total electrical energy consumed by electr...
