The temperature sensor 17 is used for detecting the temperature of the food in the cup 12, and the control component controls the heating power of the heating pipe according to the temperature detected by the temperature sensor 17, so as to control the heating process of the food. Because the heating component adopts a plurality of heating pipes 13, the heating pipes 13 are distributed at intervals along the circumferential direction of the heat conducting disc and are arranged radially oppositely, when the heating is carried out through the heating pipes 13, the whole cup body 12 is heated more uniformly, and the problem of accumulation of food caused by uneven heating is greatly reduced.
According to the technical scheme, the main machine 200 and the cup body assembly 100 supported on the stirrer are arranged, so that the cooking electric appliance is formed, wherein the cup body assembly 100 comprises a cup body 12, a temperature sensor 17, a heat conducting disc and a heating pipe assembly. The heating pipe assembly comprises at least two heating pipes 13, and the at least two heating pipes 13 in the heating pipe assembly are distributed at intervals along the circumferential direction of the heat conducting disc and are symmetrically arranged. When the cooking appliance is heating, the control assembly controls the heating pipe 13 to heat the cup body assembly 100, and food flows from the high-temperature side to the low-temperature side during heating, so that the food in the cup body assembly 100 is fully heated in the cup body 12, accumulation of the food is avoided, the food is heated more uniformly, and the taste of the food is improved.
Specifically, the wall breaking machine comprises a cup body assembly 100 and a host 200 arranged below the cup body assembly 100, wherein the cup body 12 assembly 100 comprises a cup body 12 and a cup cover 11 covered on the cup body 12, a motor 21 and a circuit board 22 are arranged in the host 200, and two heating pipes 13, a temperature sensor 17, a first temperature controller 15, a second temperature controller 16 and a stirring knife 18 are arranged in the cup body assembly 100; the controller, resistor, capacitor and other electronic components are integrated on the circuit board 22; one heating pipe is electrically connected with the circuit board 21 through the first temperature controller 15, the other heating pipe is electrically connected with the circuit board 22 through the second temperature controller 16, and the thermistor 16 is electrically connected with the circuit board 21; the motor 21 is connected to the stirring blade 18 through a transmission shaft (not shown) to rotate the motor 21.
In particular, at least two of said heating pipes 13 are distributed on the same circumference. The heating pipe 13 may be horseshoe-shaped, circular ring-shaped, circular arc-shaped extending along the circumferential direction of the heat conducting disc, etc.
In this embodiment, the heating pipes 13 are all arc-shaped, and the arc radii of the heating pipes 13 are the same as the circumference radii of the heating pipes 13, and a circumferential gap is provided between adjacent heating pipes 13.
Furthermore, the heating pipes 13 can also be distributed over different circumferences. The plurality of heating pipes 13 are all arc-shaped, and the arc radius of at least one heating pipe 13 is different from the arc radius of other heating pipes 13, and the heating pipes 13 are distributed on the same circumference as the arc radius. The end of the heating pipe 13 with small arc radius extends to the sector area surrounded by the heating pipe 13 with large arc radius adjacent to the end.

Generally, the number of heating pipes is set within a reasonable range due to cost and size constraints. In this embodiment, the number of heating pipes 13 of the cooking appliance is preferably set to 2 to 4.
In the embodiment of the invention, an even number of heating pipes 13 are preferably adopted, and each heating pipe 13 is a heating pipe 13 with the same power, so that food in the cooking appliance is heated more uniformly during heating. In this embodiment, the power range of the heating tube 13 is 500w to 1500w, and the total power range of the heating tube assembly is 800w to 2000w.

In this embodiment, the number of heating pipes can be flexibly set according to the size of the heat conducting plate and the size of the heating pipes. Compared with two heating pipes, the three heating pipes are arranged, so that the heating uniformity can be further improved, and the heated food has better taste.
