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.

In the above embodiment, the second temperature sensor 22 detects the temperature inside the tub 20 (i.e., inside the processing space 200), and can transmit the detected temperature value to the control circuit board 16 through the upper coupler 213 and the lower coupler 15 in sequence. The control circuit board 16 can determine whether to output current to the heat generating member 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 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 current to the heat generating member 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 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, so as to control the heat generating component 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. To the implementation that does not set up temperature sensor in the cooking bucket, control circuit board can directly control the work of cooking machine according to the temperature value that first temperature sensor 363 obtained. Of course, in some other embodiments, the food processor may not be provided with the first temperature sensor, and one of the second temperature sensor and the third temperature sensor may be provided to obtain the corresponding temperature value.

In addition, the bottom of the receiving barrel 111 is located in the notch 1133, so that the food processor can be miniaturized, because the notch 1133 extends from the side wall (the edge of the first side wall 1132 extends into the first side wall 1132, and the side wall is vertically placed, the overall height of the food processor can be reduced, one part of the receiving barrel 111 is located above the motor receiving cavity 113, and the other part is located above the driving board receiving cavity 114, so that the overall width of the food processor can be reduced, and in sum, the height and the width can be smaller, so that the product is miniaturized, of course, the skilled person can understand that the driving board heat dissipation air duct and the motor heat dissipation air duct can be arranged in other ways, in this case, the receiving barrel 111 is located in the receiving barrel 115 to form the motor heat dissipation air duct with the cavity wall of the motor receiving cavity 113, the part of the receiving barrel 111 located above the motor receiving cavity 113, and the part of the main body middle cover 11, at least the wall of the drive board accommodating cavity 114 and the part of the main body middle cover 11b above the drive board accommodating cavity 114 constitute a drive board heat dissipation air duct, for example, the first side wall 1132 common to the motor accommodating cavity 113 and the drive board accommodating cavity 114 is not provided with the notch 1133 and is directly connected to the side wall of the opening of the bottom of the accommodating barrel 115, for example, in fig. 15, the first side wall 1132 is moved to the right to be connected to the side wall of the opening of the bottom of the accommodating barrel 115 of the main body middle cover 11b, so that the drive board heat dissipation air duct is only enclosed by the wall of the drive board accommodating cavity 114 and the corresponding part of the main body middle cover, and in this embodiment, the food processor is wider than the embodiment illustrated in fig. 14 to 16.

Referring to fig. 16, in some embodiments, in order to prevent the water in the cooking barrel 2b from overflowing and accumulating inside the main body assembly 1b, the bottom of the accommodating barrel 111 of the main body upper cover 11a of the main body assembly 1b is provided with an upper cover hollow column 118 communicated with the inside of the accommodating barrel 111, and the main body lower cover 11c is provided with a lower cover hollow column 119 inserted into the upper cover hollow column 118. Thus, the lower cap hollow column 119 and the upper cap hollow column 118 constitute a drainage channel through which water flows toward the bottom of the accommodating tub 111 along the sidewall of the accommodating tub 111 and is drained in case that the cooking tub 2b overflows with water.

It should be noted that, in other embodiments, the upper cover assembly may be mounted on the main body assembly without being reversible, and directly covers the main body assembly and the cooking barrel, and accordingly, the upper cover assembly and the main body assembly are independent assemblies.
