Abstract

The utility model relates to the technical field of electric appliance products, in particular to an electric circuit control device of an electromagnetic induction heating product, thereby reducing the power consumption of switch power supplies. The device comprises a switch power supply circuit and a CPU and a main return circuit which are controlled by the switch power supply circuit, wherein a low power consumption electronic control device is connected into the input end of the switch power supply circuit, and the low power consumption electronic control device outputs control signals to control the work of the switch power supply circuit. The device utilizes the switching function of the lower power consumption electronic control device to enable the switch power supply circuit to be in a controlled state, even if a power supply plug is not cut off, the switch power supply circuit can not be in a power consumption standby state, then the depletion of the part can not occur, thereby realizing the efficacies of saving energy and protecting environment, simultaneously false operation of the switch power supply circuit can be avoided, the safety is good, and the efficacy of the standby power consumption of the switch power supply is reduced.

Description

Reduce the device of the Switching Power Supply power consumption of electromagnetic induction heating product

Technical field:

The utility model relates to the electric equipment products technical field, refers in particular to a kind of circuit control device of electromagnetic induction heating product, reduces the Switching Power Supply power consumption to reach.

Background technology:

Traditional electric equipment products are as the electromagnetic induction heating product, under the situation of not extracting attaching plug, though do not start electrical work, but owing to the rectification circuit on electrical equipment switch inside power circuit and the major loop, filter circuit etc. all are in the stand-by operation state, produce power consumption, promptly cause the electric equipment products stand-by power consumption, the waste electric energy, if so long-time, power consumption is bigger, concerning the whole country and even the whole society, the significant wastage energy is so improve for being necessary in fact.

The applicant is because the problem of the Switching Power Supply power consumption of above-mentioned known electric equipment products, the spirit of adhering to the research innovation, keeping on improving, utilize its professional eye and professional knowledge, work out a kind of applied range, meet the circuit arrangement of reduced stand-by power consumption of the social desirability of energy-conserving and environment-protective.

Summary of the invention:

It is a kind of simple in structure, novel that the purpose of this utility model is to provide, the convenient use, and the device of the Switching Power Supply power consumption of the reduction electromagnetic induction heating product of working stability.

For achieving the above object, the utility model adopts following technical scheme:

Reduce the device of the Switching Power Supply power consumption of electromagnetic induction heating product, include the CPU and the major loop of the control of switching power circuit and switching power circuit, input at switching power circuit inserts a low power dissipation electron control device, the work that low power dissipation electron control device output control signal is come the control switching circuit.

The utility model mainly is that the input at switching power circuit inserts a low power dissipation electron control device, the work that low power dissipation electron control device output control signal is come the control switching circuit; Make switching power circuit be in a kind of slave mode, even without the plug of cutting off the electricity supply, switching power circuit can not be in the state of power consumption standby, this part loss can not taken place, reach the effect of energy-saving and environmental protection, guarantee that simultaneously switching power circuit misoperation can not occur, fail safe is good, reaches the effect that reduces the Switching Power Supply stand-by power consumption.

Description of drawings:

Accompanying drawing 1 is a functional-block diagram of the present utility model.

Embodiment:

Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:

See also shown in Figure 1, it is the structural representation of preferred embodiment of the present utility model, the utility model is the relevant circuit arrangement that reduces the Switching Power Supply power consumption, include the CPU 20 and the major loop 30 of the control of switching power circuit 10 and switching power circuit, at the input of the switching power circuit 10 low power dissipation electron control device 40 that inserts in parallel, the work that low power dissipation electron control device 40 output control signals are come control switching circuit 10; Low power dissipation electron control device 40 is provided with a switch 41, is used to control. and low power dissipation electron control device 40 can be bistable state control device etc., and the output control signal is to reach the work of opening or closing corresponding controlled part.

Operation principle is as follows:

When low power dissipation electron control device 40 electric back output inhibition signal causes switching power circuit 10 and quits work, as export a low level or high level signal, can cause switching power circuit 10 quits work, like this, even without the plug of cutting off the electricity supply, switching power circuit 10 can not be in the state of power consumption standby, self no current not only, idling consumption can not take place, and also no-voltage output, CPU 20 and major loop 30 no starting resistors quit work, make the partial circuit that comprises in the electric equipment products in switching power circuit 10 and the major loop 30 all idling consumption can not take place, reach energy-conservation, the effect of environmental protection.

When pressing switch 41, make low power dissipation electron control device 40 output signals cause switching power circuit 10 startup work, output voltage is given CPU 20 and major loop 30, makes CPU 20 and major loop 30 get electric work, electrical equipment operate as normal.

Certainly, electrical equipment self also has conventional starting switch, when stopping electrical work, can close this starting switch earlier, and off switch 41 then, and 10 work of shutdown switch power circuit can reach and reduce the Switching Power Supply stand-by power consumption.Though low power dissipation electron control device 40 self also has idling consumption, comparatively speaking, the idling consumption of low power dissipation electron control device 40 is then much smaller relatively, has also just reached the effect of energy-saving and environmental protection.

Above embodiment is the utility model preferred embodiment only, is not to limit practical range of the present utility model with this, so every principle according to the utility model is done the equivalence variation or modified, and all should be covered by in the protection range of the present utility model.
