The wall socket circuit provided by the invention has the specific working principle that:
firstly connecting a live wire L and a zero wire N to a 220V commercial power, then connecting a power plug of the electric cooker to a CZ1 socket, pressing a button switch AN1 (closing the button switch AN1), switching on the 220V voltage of the live wire L through the button switch AN1, then reducing the voltage through a capacitor C1, outputting a direct current voltage through a bridge rectifier circuit consisting of diodes D1-D4, stabilizing the voltage through a voltage stabilizing diode VD1, filtering the voltage through the capacitor C5, outputting a 12V direct current voltage, charging the capacitor C2 through a resistor R3, simultaneously connecting the voltage to a base electrode of a triode Q1 through a resistor R4, reducing the base electrode voltage of the triode Q1 while charging the capacitor C2, conducting the triode Q1, positively conducting the 12V direct current voltage through a diode D6, outputting a 12V voltage, connecting the voltage to AN emitter electrode of the triode Q1, outputting a high level after the collector electrode of the triode Q1 is conducted, connecting the base electrode to a base electrode of a triode Q2 through a resistor R5, conducting the Q2, the collector outputs low level to electrify the coil of the relay J1 to make the normally open contact J1-1 attract and be connected, after the coil of the relay J1 is electrified and works, the normally open contact J1-1 attracts, 220V voltage of the live wire L is connected through the normally open contact J1-1 to output 220V voltage to supply power for the CZ1 socket, so that the electric cooker connected to the CZ1 socket is electrified and works.
After the electric cooker is powered on to work, the coil 1 and the coil 2 of the reed switch current transformer LT1 connected in series on the live wire L generate an alternating current magnetic field, so that the reed switch 3 and the reed switch 4 inside the reed switch current transformer LT1 enter a closed state from an original normally open state, and 12V voltage on the positive electrode of the capacitor C5 is output to 12V voltage through the switch 3 inside the closed reed switch current transformer LT1 and is divided into two paths: one path of the current is used for charging a capacitor C4, the other path of the current is positively conducted through a diode D12 and then outputs a high level which is connected to the base electrode of a triode Q4 through a resistor R10, so that the triode Q4 is conducted, the collector electrode outputs a low level which is connected to the base electrode of a triode Q3 through a resistor R7, the voltage of the base electrode of the triode Q3 is pulled down, the triode Q3 is conducted, the high level output by the collector electrode keeps the triode Q2 conducted through a resistor R5, a relay J1 keeps an electric working state, a normally open contact of the relay J1 keeps a pull-in connection state, a CZ1 socket keeps a commercial power 220V output state, and the electric rice cooker keeps an electric working state; at this time, the button switch AN1 is pressed again, when not pressed, namely in the off state, the capacitor C2 is fully charged after 2 minutes, so that the base voltage of the triode Q1 is at 12V, the triode Q1 is cut off, no high level output is generated at the collector, when the button switch AN1 is cut off, the triode Q1 is cut off, but after the electric cooker connected to the CZ1 socket is electrified and operated, a magnetic field is still generated at the coil of the reed switch type current transformer LT1 to keep the reed switch in the on state, so that the diode D12 is kept in the on state, the triode Q4 is kept in the on state, the triode Q3 is still kept in the on state, the triode Q2 is kept in the on state, the relay J1 is kept in the electric operating state, and the normally open contact J1-1 is kept in the on state, so that the CZ1 socket is kept at 220V voltage for power supply, and the electric cooker is kept in the electric operating state.
When the electric cooker is in a heat preservation state after being electrified, the power of the electric cooker is about 50W, an alternating current magnetic field cannot be generated at pins 1 and 2 of a reed switch current transformer LT1 to disconnect pins 3 and 4, no 12V voltage is output at pin 3, the voltage charged on a capacitor C4 is discharged from a diode D12 to the emitter to the cathode through a resistor R10 to a base electrode of a triode Q4, the triode Q4 is kept on, the triode Q3 is kept on, the triode Q5 is kept on, the relay J1 is kept in a pull-in working state, the CZ1 socket electric cooker is kept at 220V voltage, and the electric cooker is still in an electrified heat preservation state. When the capacitor C4 discharges for 10 minutes, the charged voltage on the capacitor C4 is discharged, at the moment, the diode D12 is cut off, the triode Q4 is cut off, the triode Q3 is cut off, the triode Q2 is cut off, the coil of the relay J1 loses power and does not work, the normally open contact J1-1 is in a normally open and disconnected state by closing, 220V voltage output does not exist on the CZ1 socket, and therefore the power supply of the electric cooker is disconnected, the electric cooker is automatically powered off after cooking is finished, and electricity is saved.
In addition, when the electric cooker is in a heat preservation state within 10 minutes after cooking and is in a heat preservation state, if the heat preservation time needs to be prolonged, after the button switch AN2 is pressed, 12V voltage is divided into two paths, one path is connected to a 2-pin trigger pin of the one-way silicon controlled rectifier VT1 through a diode D7 forward conduction resistor R9, the one-way silicon controlled rectifier VT1 is conducted, a 3-pin output high level is connected to the anode of a red light emitting diode LED1 through a resistor R8 in a voltage reduction mode, the cathode of the red light emitting diode LED1 is connected to the cathode of a 12V power supply, the red light emitting diode LED1 is powered to emit light, the other path of the 12V voltage is conducted through a button switch AN2 in a forward conduction diode D8 and then outputs 12V voltage to rapidly charge a capacitor C3, after the button switch AN2 is disconnected, the diode D8 is cut off, at the moment, the voltage charged on the capacitor C3 is discharged to the base of a triode Q4 to the cathode of the emitter through the triode Q4 through the resistor R10 after the button switch AN 35 10 is conducted, and the triode Q4 is kept conducted, the triode Q3 is kept on, the triode Q2 is kept on, the relay J1 is kept in an electrified working state, the normally open contact J1-1 is kept in an attraction state, 220V voltage is still connected to the CZ1 socket, the electric rice cooker is still kept in an electrified heat preservation state, after 1 hour, after the charged voltage on the capacitor C3 is discharged, the diode D10 is cut off, the triode Q4 is cut off, the triodes Q3 and Q4 are both cut off, the relay J1 is not powered off, the normally open contact J1-1 is cut off, 220V voltage does not exist in the CZ1 socket, the power supply of the electric rice cooker is powered off, the electric rice cooker is powered off after the heat preservation is carried out for 1 hour, the function of automatically powering off after the electric rice cooker is not used is achieved, and the fire safety hazard caused by the fact that the electric rice cooker is powered on and burnt dry when the electric rice cooker is not used is prevented.
The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
