A control circuit of the electric cooker, including cooking normally open touch switch, relay, the heating plate and the sudden jump temperature limiter, heating plate with jump type temperature limiter, relays with three terminals, a terminal of a first terminal group relay coil is connected with the second sets of relay contacts. After the end of the boiling switch connecting the power supply, the other end is another terminal contacts are connected to power supply the first group of the relay coil another terminal and the second terminal end of a relay group, third groups of relay contacts often Kaijing by jump type temperature limiter is connected with the heating disk and a terminal the power supply, another terminal connected to another terminal of the heating plate. The utility model can also comprise an insulating sheet, and the relay can also be provided with fourth sets of terminal posts, wherein, the fourth groups of relays are normally closed, and a terminal post of the static contact is suspended, and the other terminal is connected with a terminal of the heating disc through the heat insulating piece. The utility model ensures the normal work of the rice cooker and has good cooking effect, and the assembly is simple and convenient.
