Full-automatic temperature limiting center switch for electric cooker

Abstract

This invention discloses an electric cooker full-automatic temperature limit center switch, which belongs to the temperature control switch technique filed, the switch includes hull, replacement spring that is fixed in the inner of the hull, temperature-sensitive device that is held in the inner of the hull by the replacement spring, wherein the inner top of the temperature-sensitive device is fixed with the temperature sensing magnet, the bottom of the temperature-sensitive device is fixed with the assembled switch, and there is a permanent magnet is fixed between the temperature-sensitive device and the assembled switch, and the outer of the temperature-sensitive device and the assembled switch is arranged with a spring; and the top of the assembled switch is arranged with an upper contact pole which can affect the switch state and is correspondent with the bottom of the permanent magnet, and the bottom of the assembled switch is arranged with a down contact pole which can affect the switch state and is correspondent with the inner bottom of the hull, and the assembled switch also is arranged with the electric power terminal of the current input end, the heating terminal that induces the switch signal and the heat preservation terminal. The advantage in this invention is that the assembling technology is simple, and it is convenient for use.

Description

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...
