Electric cooking pot enter open state after, user can click on be arranged on operation and display module 80 on function by Key, so that electric cooking pot enters cooking process.
After the cooking time that electric cooking pot cooks completion or sets terminates, the self-starting of timer 15 simultaneously starts timing.When Timing time is not up in preset time, and electric cooking pot is in function and waits holding state.
After the timing time of timer 15 reaches preset time, the output end OUT1 and output end OUT2 of main control unit 13 Output control signal simultaneously, so that the first triode Q1 and the second diode Q2 end simultaneously, and then cause hilted broadsword relay K1 Disconnected with two keys relay K2, electric cooking pot is hence into holding state.
It should be noted that when the first triode Q1 is NPN type, the output end OUT1 output low levels of main control unit 13 Signal, so that the first triode Q1 ends.When the first triode Q1 is positive-negative-positive, the output end OUT1 outputs of main control unit 13 High level signal, so that the first triode Q1 ends.When the second triode Q2 is NPN type, the output end of main control unit 13 OUT2 exports low level signal, so that the second triode Q2 ends.When the second triode Q2 is positive-negative-positive, main control unit 13 Output end OUT2 exports high level signal, so that the second triode Q2 ends.
After the first triode Q1 cut-offs, hilted broadsword relay Relay1 coil KM1 both ends do not have potential difference, coil KM1 Dead electricity, the switch K1 between hilted broadsword relay Relay1 the first contact and the second contact disconnect so that surge detection module 61, Zero passage detection module 62 and voltage sample module 63 power off, and electric cooking pot enters holding state.It should be noted that the one or three The moment of pole pipe Q1 cut-offs, because the electric current in coil KM1 can not sport zero, coil KM1 both ends produce a high voltage Induced electromotive force, induced electromotive force caused by coil KM1 can be discharged by the first diode D1, so as to avoid the one or three Pole pipe Q1 is breakdown, while can eliminate interference of the induced electromotive force to other components.
Meanwhile after the second triode Q2 cut-offs, two keys relay Relay2 coil KM2 both ends do not have potential difference, line KM2 dead electricity is enclosed, the switch K2 between two keys relay Relay2 first to fourth contact disconnects so that synchronized sampling module 40 Power-off, electric cooking pot are in holding state.It should be noted that in the moment of the second triode Q2 cut-offs, due in coil KM2 Electric current can not sport zero, coil KM2 both ends produce the induced electromotive force of a high voltage, sense caused by coil KM2 Electromotive force can be discharged by the second diode D2, so as to avoid the second triode Q2 breakdown, while can eliminate sensing Interference of the electromotive force to other components.
In addition, user when the working time of electric cooking pot being not up to cooking time, can send shutdown by the button that shuts down Instruction, main control unit 13 is after shutdown command is received, its output end OUT1 and output end OUT2 while output control signal, with Make the first triode Q1 and the second diode Q2 while end, electric cooking pot enters holding state.Thus, can forcibly control Electric cooking pot does not continue to perform cooking process.
It should be noted that hilted broadsword relay Relay1 and two keys relay Relay2 in Fig. 4 can be replaced other The relay of type, is specifically no longer limited here.
In order that obtaining those skilled in the art more clearly understands the utility model, as shown in figure 5, of the present utility model be used for Reducing the control method of the stand-by power consumption of electric cooking pot may include following steps:
S101, switch on power, electric cooking pot carries out initial configuration.
