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

Along with improving constantly of living standard, various electrical equipment emerge in an endless stream.At present, such as televisor, air-conditioning, set-top box, DVD/VCD machine, remote control electric fan etc., household electrical appliance indispensable in people's daily life have been become.These electrical equipment are conveniently controlled its work by telepilot usually.Most of telepilots have the function of shutdown.With the televisor is example, after people normally finish watching TV, just gets over by the closing key of telepilot.This is worthless in fact.Because this only is that the high voltage in the televisor is partly cut off, the image of having closed machine shows and sound accompaniment, and the part of the power rectifier in the machine, remote signal receiving unit and power supply etc. are still in running order.Just reduced consumption rate, if overlong time, except the power consumption of meaningless ground of televisor also can cause the televisor heating, inner electrical equipment and other component agings influence serviceable life.So remote control transmitter " shutdown " button is that the power switch that can not make colour TV uses, and has only the state that the power switch on the machine is in " wait ", and uses the appliance switch circuit of above-mentioned power saving function to shut TV veritably.Other are such as video recorder, stereo set, remote control fan etc.. the telepilot of all electrical equipment all is a principle of uniformity.

Have only with the power supply on the machine fully with the state of electrical network disconnection, could be with machine shutting truly.But the power switch of a lot of families is arranged on the back of machine, and it is very inconvenient directly to shut power switch.And a lot of people are owing to the effect of inertia, and the custom of not cutting off the electricity supply after using machine is the operation of shutting down by telepilot.There are three big defectives in this operation:
