The utility model belongs to the household electrical appliance control technology, and it is specially adapted to family expenses drone version electrical equipment.

Remote control system popularizing in household electrical appliances brings great convenience to the user, and the holding state of blemish in an otherwise perfect thing need consume certain energy.The power consumption of single equipment is insignificant, but huge numbers of families' household electrical appliances accumulate over a long period, and power consumption is just considerable.It is reported, U.S.'s household electrical appliance, the electricity cost of holding state is annual above 1,000,000,000 dollars.The investigation of German federal environment office shows that the power consumption of stand-by power supply accounts for 10% of the electricity charge, and power consumption reaches 20,000,000,000 Kwh, surpasses the Bai Lin whole city power consumption summation of the whole year.In China, GB is not strict to the requirement of family appliance standby power consumption, as the colour TV stand-by power consumption all more than 1.5W, and the Chinese Color TV owning amount is more than 200,000,000, the power consumption of useless stand-by power consumption is considerable, this shows that the power consumption when reducing the household electrical appliance standby is a significant conservation measures.On the other hand, because the backwardness of family appliance standby consumption-reducing technological, China's this technical indicator of outlet family appliance standby power consumption is compared with external household electrical appliances still big gap, and competitiveness is not strong.And in Japan, realize to the whole people's environmental protection and energy saving from government, environmental protection, news media, pay attention to this important indicator of family appliance standby power consumption invariably, the advertisement of businessman is more indicated stand-by power consumption in remarkable position, this is the embodiment of technical strength, also is the important references index of consumer when buying.Therefore, the utility model can also improve this series products competitiveness in the international market greatly.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, power consumption can be reduced to minimum device when a kind of family appliance standby state is provided.

The technical solution of the utility model is finished like this: this built-in family appliance standby loss reducing device, comprise alternating current AC, drone version household electrical appliances and control circuit, it is waited to levy the two ends that are alternating current and is connected with the input of power source special respectively, the output of power source special receives with remote signal and control circuit is connected, remote signal receives and the output of control circuit is connected with K switch, and remote signal receives and the feedback input end of control circuit is electrically connected with remote control man.

The utlity model has following advantage: compare with colour TV stand-by power consumption under the remote-control closedown state, the existing colour TV of China is generally greater than 1.5W, and the best level of Japanese colour TV is 0.25W, and the utility model can realize that then power consumption is less than 30mW; When remote-control closedown, switching power supply and microprocessor CPU, memory EEPROM, adopt the utility model technology then not work, thereby have reduced power consumption still in work with prior art; Because it is minimum that stand-by power consumption is reduced to, minimumly be lower than 10mW, improved product competitiveness in the international market greatly, improved economic benefit, energy savings and capacity to earn foreign exchange through exports for enterprise, for country.

Control line map for the utility model device in Fig. 1, Fig. 3 frame line.

Now further describe embodiment: earlier in conjunction with Fig. 1 in conjunction with Fig. 1, Fig. 3, this built-in family appliance standby loss reducing device, comprise alternating current AC, drone version household electrical appliances and control circuit, it is waited to levy the two ends that are alternating current and is connected with the input of power source special respectively, the output of power source special receives with remote signal and control circuit is connected, and remote signal receives and the output of control circuit is connected with K switch, and remote signal receives and the feedback input end of control circuit is electrically connected with remote control man.

Now further specify its control circuit and operation principle in conjunction with Fig. 3:

After the drone version colour TV being shut down with remote controller, the kickback transformer of colour TV quits work, give the remote signal reception of loss reducing device and the feedback voltage vanishing of control circuit, D3, R12 gives the energy supplement vanishing of loss reducing device power source special, a little less than the load capacity of power source special, the voltage at capacitor C 1 two ends descends gradually, simultaneously because through D4, R13 gives the energy supplement vanishing of C3, C3 is through R8, R9 and Q5 release energy, finally cause Q5 to end, relay R L01 disconnects, and this moment, the alternating current of drone version colour TV was cut off, power consumption is zero, and the power consumption of complete machine is exactly the quiescent dissipation of loss reducing device.After Fig. 3 repeat circuit disconnects, the load of the power source special of loss reducing device has only the remote control receiver window, the quiescent dissipation of remote control receiver window is about 10 milliwatts at present, because the efficient under the state of output 10 milliwatts of the power source special among Fig. 3 can reach 50%, so the quiescent dissipation of loss reducing device is about 20 milliwatts.

Introduce the operation principle of the power source special among Fig. 3 below.

Power source special among Fig. 3 is made up of D1, D2, R1, R2, Q1, Q2, Q3, Q4, ZD1, ZD2, D1, D2 form half-wave rectifying circuit, alternating current is carried out halfwave rectifier, when the half-wave voltage of D2 negative electrode is hanged down, ZD1 ends, and Q4 ends, and alternating current is powered to Q3 through R2, electric current after Q3, Q2, Q1 amplify gives capacitor C 1 charging, makes CP01 obtain operating voltage.When the half-wave voltage of D2 negative electrode rises to certain value, ZD1 conducting, Q4 conducting, DA causes Q1, Q2, Q3 to end.Q7, ZD3 only play the overvoltage protection effect among the figure.Want as seen thus, only in the low-pressure end work of alternating current, and irrelevant with the high pressure of alternating current, the voltage outputting stablizing effect is good, the efficient height for this power source special.Certainly, as long as adopt the circuit structure of this device, selected along with the continuous reduction of remote control receiver window quiescent dissipation and relevant circuit parameter, stand-by power consumption should be reduced to below the 10mW.

Wake up, start

When pressing any key of remote controller, the pulse signal that remote controller sends is received the back by the output of the 3rd pin by remote control receiver window CP01, owing to contain low level in the pulse signal, cause Q6 moment conducting, C3 is recharged, then Q5 conducting, relay R L01 conducting, the alternating current of drone version colour TV is switched on.At this moment, if colour TV directly enters normal operating conditions, then the kickback transformer of colour TV is started working, and feedback voltage is given loss reducing device through D3, R12, D4, R13, and the conducting state of relay is maintained, and colour TV works on; If colour TV enters holding state, the kickback transformer of colour TV quits work during owing to standby, is directed at no feedback signal, and the conducting state of relay can't be kept, and postpones to disconnect after the several seconds, and complete machine enters the holding state of extremely low power dissipation again; If during the colour TV standby, distant pocket sends normal power-on pulse again, and then colour TV can enter normal operating conditions and keep.

The VR of cross-over connection in the alternating current two ends is piezo-resistance among the figure, and protection subtracts the consumption control circuit, avoids the destruction of the abnormal pressure in the alternating current.

For improving antijamming capability, also can meet a miniature CPU after the remote control receiver window CP01, and relay also can be used semiconductor relay instead, specifically depends on practicality and cost requirement.
