Abstract
The utility model relates to a circuit reducing whole machine standby power consumption. The circuit comprises a 12V voltage output module, a 5V voltage output module and an intelligent control unit. The 5V voltage output module is used for supplying working voltage to the intelligent control unit and other 5V-system loads. The circuit is characterized in that the 12V voltage output module supplies input voltage to the 5V voltage output module via a switch device. The intelligent control unit controls turn-off of the switch device, and the switch device is maintained in the closed state through control. A 5V power supply turn-off and wake-up control module is respectively connected with the intelligent control unit and the switch device. The 5V power supply turn-off and wake-up control module comprises a switch module. The utility model also provides a method adopting the aforementioned circuit. The control circuit which is simple and low in cost is designed. Turn-off and turn-on of the whole machine 5V working voltage are realized via a chip control and button wake-up method. After all the 5V-system loads (including the intelligent control unit) are turned off, the whole machine standby power consumption can be greatly reduced.
Description
Technical field
The utility model relates to a kind of circuit that reduces complete machine stand-by power consumption, belongs to household electrical appliances economize on electricity field.
Background technology
Which part electric equipment products power circuit, as the vitals of electric equipment products, does not have do not need power supply to arrange.Because increasing electric equipment products enter family and all trades and professions, there is the electrical equipment of quite a few for a long time in holding state.So, the power consumption of the huge electric appliance standby of these quantity just must be taken seriously.The LCD televisor of current family expenses of take is example, is produced in the type before 2008, and stand-by power consumption is greater than 10W; The type stand-by power consumption of later producing for 2008 is not less than 3W; The product stand-by power consumption of producing before 2011 is not less than 1W.In order to address the above problem, circuit design can be become to the circuit that stand-by power consumption is very low, as replacing triode, metal-oxide-semiconductor makees switch, and power supply is made the scheme of low-power consumption, can reduce to a certain extent stand-by power consumption, but inevitably can increase circuit cost.
At present according to news, country is in the standard of studying and defining about household electrical appliances complete machine stand-by power consumption, and stand-by power consumption when following meeting mandatory requirement machine is not worked can not surpass 1W.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of method that reduces the circuit of complete machine stand-by power consumption and adopt this circuit.
In order to solve the problems of the technologies described above, a technical scheme of the present utility model has been to provide a kind of circuit that reduces complete machine stand-by power consumption, comprise 12V Voltage-output module, 5V Voltage-output module and intelligent control unit, 5V Voltage-output module for intelligent control unit and other 5V be that load provides operating voltage, it is characterized in that: 12V Voltage-output module provides input voltage via switching device for 5V Voltage-output module, the shutoff of intelligent control unit gauge tap device, and gauge tap device remains on closure state, 5V power supply is turn-offed and is waken control module up and be connected respectively intelligent control unit and switching device, 5V power supply is turn-offed and is waken control module up and comprises switch module, by the action of switch module, by 5V power supply, turn-off and wake control module up and provide switching device cut-off signals to intelligent control unit, simultaneously, action by switch module is closed by switching device.
Preferably, also comprise 5V power supply off state indicating member, by the action that switch module in control module was turn-offed and woke up in power supply according to 5V of described intelligent control unit by 5V power voltage output end conducting or the cut-off of off state indicating member and described 12V Voltage-output module.
The utility model has been designed one simply and control circuit cheaply, by chip controls and button awakening method, is realized the shutoff of complete machine 5V operating voltage and is opened.After 5V is the whole power-off of load (comprising intelligent control unit), can significantly reduce the stand-by power consumption of complete machine.
Accompanying drawing explanation
A kind of block diagram that reduces the circuit of complete machine stand-by power consumption that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 1, the utility model provides a kind of circuit that reduces complete machine stand-by power consumption, comprise 12V Voltage-output module, 5V Voltage-output module and intelligent control unit, 5V Voltage-output module provides operating voltage for intelligent control unit and working cell, 12V Voltage-output module provides input voltage via switching device for 5V Voltage-output module, the shutoff of intelligent control unit gauge tap device, and gauge tap device remains on closure state, 5V power supply is turn-offed and is waken control module up and be connected respectively intelligent control unit and switching device, 5V power supply is turn-offed and is waken control module up and comprises switch module, by the action of switch module, by 5V power supply, turn-off and wake control module up and provide switching device cut-off signals to intelligent control unit, simultaneously, action by switch module is closed by switching device.
For the ease of operation, the utility model also comprises 5V power supply off state indicating member, by the action that switch module in control module was turn-offed and woke up in power supply according to 5V of described intelligent control unit by 5V power voltage output end conducting or the cut-off of off state indicating member and described 12V Voltage-output module.
The method of the reduction complete machine stand-by power consumption of foregoing circuit, the steps include:
When complete machine works, closure state by intelligent control unit maintained switch device, 12V Voltage-output module is to offer 5V Voltage-output module after 12V voltage by the 220V voltage transitions of input, by 5V Voltage-output module, provide operating voltage for intelligent control unit, now, the voltage output end cut-off of 5V power supply off state indicating member and described 12V Voltage-output module;
When complete machine enters standby, the switch module that is turn-offed and waken up in control module by operation 5V power supply provides cut-off signals to intelligent control unit, after intelligent control unit obtains this cut-off signals, gauge tap device makes its shutoff, the voltage output end conducting of off state indicating member and the described 12V Voltage-output module of simultaneously 5V being powered, by 5V power supply off state indicating member, to operating personnel, provide indicator signal, after 5V Voltage-output module dead electricity, intelligent control unit and the working cell voltage of losing the job quits work, and complete machine enters holding state;
When complete machine is waken up by holding state, the switch module that turn-offs and wake up in control module by operation 5V power supply makes switching device moment closure, 5V Voltage-output module obtains electric work, for intelligent control unit provides operating voltage, by intelligent control unit, switching device is remained on to closure state, complete machine enters duty.
