How to wire the inside of a mechanical rice cooker without a circuit board?
There are a total of 11 threads, two white threads of the insulation sheet.
Three 220-volt power cables, one is a red wire [live wire], the other is a blue wire [neutral wire], and one is a yellow and green wire [ground wire].
There is a three-pin micro switch on the two-color light board, with characters facing itself, arranged from left to right [as shown in Figure 4],
A total of two in-line color ring resistors are installed on the two-color indicator board, two in-line indicators [the cooking indicator is bright red, and the heat preservation indicator is bright yellow], a micro switch, and an in-line diode, a total of 6 wires, two red wires [the in-line insulation indicator has two pins, the first red wire is connected to a pin of the thermal insulation indicator] [the second red wire is connected to the first pin of the micro switch, and then the first in-line color ring resistor is connected to any pin, Then connect the negative pole of an in-line diode], three blue wires [the third blue wire and the fourth blue wire should be connected to the third pin of the micro switch at the same time] [the fifth blue wire should be connected to one pin of the in-line cooking indicator, and then connect the remaining positive pole of the in-line diode], and the last one is a white wire [connect any pin of the second in-line color ring resistor].
220 volts, a red wire [live wire] from the pinzi socket, connected to one end of a temperature protection, the other end of the temperature protection is connected to the left pin of the heating plate [the bimetal sheet of the contact switch is facing forward] [as shown in Figure 1] [the left pin of the heating plate is only connected to two wires], and then connected to a red wire from a pin of the thermal insulation indicator light],
Connect two wires on the right side of the heating plate (as shown in Figure 1), a red wire from the first pin of the micro switch, and any white wire from the insulation sheet, and screw the pins on the right side of the heating plate together.
The right binding post of the contact switch is connected with only one wire, and the left binding post is connected with a total of three wires.
Two blue wires connected together are drawn from the light board, the other end of one blue is connected to any pin of the thermostat, and the other blue end is the binding post on the right side of the contact point switch.
The binding post on the left side of the contact switch is connected to the white wire left by a thermal insulation sheet, and a white wire is connected from the lamp board [a white wire is connected to any pin of the second in-line color ring resistor], and then a blue wire is connected from the binding post of the 220 volt word socket [zero wire, no need to distinguish between positive and negative poles].
The ground wire binding post of the 220 volt socket is connected to a yellow and green two-color wire, and the other end of the ground wire is connected to the shell of the rice cooker [as shown in Figure 1].
