When the temperature sensor 6 is rotated relative to the pot body 1 by the mounting bracket 5, the lower end of the thermometer 6 can be inserted into the pot 2 through the through hole 4, and The temperature can be detected by direct contact with the food in the pot 2, and the temperature sensor 6 transmits the detected temperature signal to the controller, which receives the signal and controls the heating device.

When in use, the thermometer 6 is rotated relative to the pot body 1 by the mounting frame 5, and the lower end of the thermometer 6 is inserted into the pot 2 through the through hole 4, and is directly in contact with the food in the pot 2 for temperature measurement, and the temperature is sensed. The meter 6 is directly electrically connected to the controller in the pot body 1, thereby transmitting the detected temperature signal to the controller, the controller receiving the signal, and controlling the working state of the heating device according to the received signal, thereby enabling the pot to Run at a pre-set temperature to ensure the quality of the cooking and make the food more delicious.

Wherein, the heating device may adopt a heating plate heating method or an IH electromagnetic heating method, and is not limited herein. The material of the pot 2 can be iron, aluminum, stainless steel, ceramics, and the like.

In the present invention, the thermometer 6 can enter the pot 2 through the through hole 4 in the lid 3, thereby directly contacting the food in the pot 2 for temperature measurement, and the method of contact type temperature measurement overcomes the deficiencies of the prior art. The temperature difference caused by heat conduction is avoided, the temperature detection is more accurate, and the cooked food is more delicious. In addition, the thermometer 6 is rotatably connected to the pot body 1 through the mounting frame 5, and the thermometer 6 can be installed. The frame 5 is inserted into the pot 2 through the through hole 4 or taken out from the pot 2, and has a simple structure and reasonable design, and can avoid the loss of the thermometer 6 and is convenient to use.

When the pot is used for low temperature cooking below 99 °C, the maximum water level of the pot 2 should be at least 2 mm lower than the lower end of the thermometer 6, that is, when the thermometer 6 is inserted into the pot 2, the lower end of the thermometer 6 is at least Located 2mm below the maximum water level of the pot 2, at this time, the thermometer 6 can fully contact the food in the pot 2, and the detected temperature error is about 0.5 °C.
