A critical water-controlled type semiautomatic electric heating cooking pot consists of a wireless coupling electric heating cooking pot body and a power coupling seat, wherein an electric heating plate and a heat-conduction connecting plate are arranged on a semi-spherical surface of a non-stick pot bottom; the heat-conduction connecting plate penetrates in a strip-shaped channel in the middle of the electric heating plate and is provided with a temperature sensor; a circular base is arranged on the heat-conduction connecting plate; a rectangular coupling socket is formed in the middle of the circular base; the left end and the right end of the coupling socket are provided with a connecting plate groove and a front and back blade groove; the heat-conduction connecting plate in the connecting plate groove and a front and back electric contact blade in the front and back blade groove are respectively in contact with an earthing spring plate and a front and back power spring plate on a coupling plug of the power coupling seat, so that power wires of the heat-conduction connecting plate and the front and back electric contact blade are in coupling connection with the coupling plug of the power coupling seat; a triangular machine box is arranged on the left side of a control handle; and an operating panel is arranged at the left upper end of the triangular machine box and is respectively provided with a high-temperature button, a high-temperature indicator lamp, a low-temperature button and a low-temperature indicator lamp. The temperatures of different regions of the surface in the pot are correspondingly changed along with change of the quantity of water in the electric heating cooking pot, and are measured and controlled according to change of a critical temperature, the electric heating cooking pot can be switched off automatically during cooking, the circumstance that a user forgets to switch off the cooking pot and food in the cooking pot is burned are avoided, the time is saved, the user does not need to worry about the food in the cooking pot, and troublesome problems are avoided.
