Abstract

A high-efficient energy-saving switch circuit comprises an infrared receiver, a single chip microcomputer, a current detecting module, a driver, a relay, a power source management module and the like. The current detecting module is used for detecting current in a power input circuit of an electric appliance and transmitting a detection signal to the single chip when the current is lower than a preset threshold value (or when the current drops suddenly). The single chip microcomputer leads the relay to be cut off through the driver after receiving the signal so as to lead the electric appliance to be completely disconnected with a power grid. After being disconnected with the power grid, the power source management module supplies power for the infrared receiver, the single chip microcomputer and the driver (power consumption is about 0.01W), and when needing to use again, a power source can be started to supply power for the electric appliance by pressing an optional key of an infrared remote controller (or a set switch key of a designed remote controller. A battery can be charged while the electric appliance is used, and a charging management module stops charging when the battery is filled. The single chip microcomputer begins to time (0 to 9999s) when receiving a standby signal of the electric appliance and optionally sets time for cutting off the power grid. The high-efficient energy-saving switch circuit is adaptable to any household electric appliance.

Description

Efficient energy-saving switch circuit
Technical field
The utility model relates to appliance field, relates in particular to a kind of appliance switch circuit with power saving function.
Background technology
