Problems solved by technology

[0002] The temperature limit switch used in the existing electric rice cooker is to manually press the lever to turn on the power supply and start cooking. After the rice is cooked, the temperature limit switch switches the circuit from the heating state to the heat preservation state through the lever connection mechanism. Many, the accumulation of dimensional deviations of each component, coupled with improper assembly process, or user misoperation and other factors, make the rice cooker often appear uncooked rice, sandwiched raw rice, burnt rice and other phenomena in the actual use of the user, and even burn out the heating plate and cause a fire tragedy.

technical field [0001] The invention relates to a temperature control switch, in particular to a fully automatic temperature-limiting center switch for an electric rice cooker. Background technique [0002] The temperature limit switch used in the existing electric rice cooker is to manually press the lever to turn on the power supply and start cooking. After the rice is cooked, the temperature limit switch switches the circuit from the heating state to the heat preservation state through the lever connection mechanism. Many, the accumulation of dimensional deviation of each component, coupled with improper assembly process, or user misoperation and other factors, make the rice cooker often appear uncooked rice, sandwiched raw rice, burnt rice and other phenomena in the actual use of the user, and even burn out the heating plate and cause a fire tragedy. Contents of the invention [0003] The object of the present invention is to provide a fully automatic temperature-limit...
