The second temperature sensor 22 and the third temperature sensor 24 can each be electrically connected to the control circuit board 16. As shown in fig. 13, the main body assembly 1b is correspondingly provided with a lower coupler 15 capable of being matched with the upper coupler 213, and the lower coupler 15 is electrically connected to the control circuit board 16. When the food processing barrel 2b is disposed in the accommodating barrel 111, the second temperature sensor 22 and the third temperature sensor 24 are electrically connected to the control circuit board 16 through the upper coupler 213 and the lower coupler 15.

Accordingly, the temperature controller 25 electrically disconnects the heat generating member 214 from the upper coupler 213, which may be considered as electrically disconnecting the heat generating member 214 from the control circuit board 16. In the above embodiment, since the heat generating member 214 is disposed at the bottom of the tub 20, heating efficiency is high for faster heating. In addition, the temperature controller 25 is installed at the bottom of the barrel 20, so that temperature measurement is accurate, and whether disconnection occurs is determined according to a measured temperature value and a threshold value, so that dry burning can be prevented.

The control circuit board 16 can determine whether to output current to the heat generating member 214 according to the temperature value detected by the second temperature sensor 22. In case of outputting the current, the current is transmitted to the heat generating member 214 through the lower coupler 15, the upper coupler 213 and the thermostat 25. The third temperature sensor 24 detects the temperature of the bottom of the tub 20, and the detected temperature value is transmitted to the control circuit board 16 through the upper coupler 213 and the lower coupler 15. The control circuit board 16 determines whether to output a current to the heat generating member 214 according to the temperature value measured by the third temperature sensor 24. In case of outputting the current, the current is transmitted to the heat generating member 214 through the lower coupler 15, the upper coupler 213 and the thermostat 25. In the above embodiment of the present application, the second temperature sensor 22 measures temperature when the liquid is present in the barrel 20, and the temperature measurement is more accurate. The third temperature sensor 24 is mainly used for measuring the temperature of liquid-free food materials during operation such as cooking with a cooking barrel or dough kneading and fermenting, and therefore more food materials can be processed by the two temperature measuring elements, and the temperature is controlled more accurately, so that more delicious food can be obtained.

It should be noted that, during the operation of the food processor, the control circuit board 16 can select one of the first temperature sensor 363, the second temperature sensor 22 and the third temperature sensor 24 to obtain a temperature value according to the operation state of the food processor, such as the function selected by the user, the temperature values obtained by the first temperature sensor 363, the second temperature sensor 22 and the third temperature sensor 24, and control the heat generating component 214 and other components of the food processor. For example, the cooking function selected by the user is to cook or the control circuit board detects that the cooking machine is currently in the working state of cooking, the temperature in the cooking barrel measured by the first temperature sensor and the second temperature sensor is lower, the temperature at the bottom of the barrel measured by the third temperature sensor 24 is higher, and the control circuit board 16 controls the cooking machine by taking the temperature value measured by the third temperature sensor 24 as a reference, such as adjusting the heating power of the heating element, and controlling the heating element to be turned off or to start working.

It should be noted that only one of the second temperature sensor 22 and the third temperature sensor 24 may be provided in the cooking bucket, or no temperature sensor may be provided. The application does not limit the method, and the method can be set according to specific conditions. For the embodiment that one of the second temperature sensor 22 and the third temperature sensor 24 can be disposed in the food processing barrel, the control circuit board can control the operation of the food processing machine according to the temperature values obtained by the first temperature sensor 363 and the control circuit board, and reference can be specifically made to the above description.
