The invention discloses an electronic thermometric pan with the function of electric generation by temperature differences of a semiconductor refrigeration piece, which mainly consists of a pan body, a handle, a temperature difference power generating system and a thermometric system. The temperature difference power generating system comprises the semiconductor refrigeration piece, a pressure-rising and voltage-stabilizing electronic component and an electric energy storage device. The thermometric system consists of a temperature sensor, a microprocessor, a circuit board and a liquid crystal piece. The temperature sensor is directly arranged at the bottom part of the pan body and the circuit board is arranged in a cavity of the handle. A cavity of the joint of the handle and the pan body is internally provided with the semiconductor refrigeration piece that is in contact with the pan body. The other surface of the semiconductor refrigeration piece is in close contact with a metal radiator. The temperature difference power generating system, the thermometric system and the liquid crystal piece are respectively connected with the circuit board. By utilizing cooking residual heat to generate power, the electronic thermometric pan of the invention realizes the temperature measurement for the bottom of the pan without battery drive, thereby not only becoming a healthy, hygienic and safe cook utensil, but also meeting the requirements of the times of environmental protection and economy; furthermore, the electronic thermometric pan of the invention also has convenient and reliable use, thereby having quite broad application prospect.
