Abstract
The utility model relates to an electric heating cooking utensil. The electric heating cooking utensil comprises a pot body and an electronic temperature sensing rod connected with the pot body in an inserting mode. The pot body is provided with a heater. The electronic temperature sensing rod comprises a shell, a circuit board and a probe, wherein the circuit board is arranged in the shell and electrically connected with the heater, and the probe is connected with the shell and detects the temperature of the pot body. A temperature sensor electrically connected with the circuit board is arranged in the probe. A thermal breaker is further arranged in the probe and electrically connected with the circuit board, and when the temperature of the pot body exceeds a preset value, the thermal breaker automatically cuts off a power supply of the heater. According to the electric heating cooking utensil, when the temperature sensor has a fault and can not accurately detect the temperature, for example, when the temperature of the pot body has been higher than the preset temperature but the temperature detected by the temperature sensor is lower than the preset temperature, the power supply of the heater will be cut off by the thermal breaker electrically connected with the circuit board, and thus safety accidents caused by the situation that the heater works continuously in the high power state are avoided.
