When detection support 3 detects that the pot is placed on the microcrystalline plate, heating wire 2 heats again. Among them, the detection principle of detection support 3 can be the same as the working principle of piezoelectric sensor, or other sensors such as weight sensor can be used. When the pot is placed on the microcrystalline plate, detection support 3 detects that the signal changes, therefore, the detected signal is transmitted to the external PCB controller, and the heating of heating wire 2 is controlled by the controller;When detection support 3 does not detect the pot, the signal does not change, at this time, the controller controls the heating of heating wire 2. The on-off of the PCB controller to control the heating wire belongs to the prior art, which will not be repeated here.

[0026] The connector 41 is provided with a through hole 411, which facilitates the insertion of one end of the detection support 42 into the through hole 411; after the one end of the detection support 42 penetrates the side wall of the heat insulation ring 1, it is inserted into the through hole 411, and through the connector 41, the fixation of the detection support 42 is facilitated.

[0027] The connecting device 4 further comprises a connecting wire 43, the detection support 3 is electrically connected with the connecting wire 43, and one end of the connecting wire 43 is fixed on the connector 41. One end of the connecting wire 43 extends into the through hole 411 of the connector 41, and in the through hole 411, the connecting wire 43 is directly connected with one end of the detection support 3. Through the connecting wire 43, the detection support 3 is facilitated to be electrically connected with the external PCB controller through the connecting wire 43, and signal transmission is facilitated.

[0028] Therefore, through the connecting device 4, the fixation of the detection support 42 on the heat insulation ring 1 is realized, and the electrical connection between the detection support 42 and the corresponding structure outside is facilitated, and the installation is convenient.

[0029] The side wall of the heat insulation ring 1 is provided with mounting holes 11, the number of the mounting holes 11 is greater than or equal to three, and the two ends of the detection support 3 are respectively fixed in the corresponding mounting holes 11.

[0030] As shown in Figures 4-9 in actual use, according to different use requirements, the detection support 3 can be triangular, circular, polygonal or elliptical, or other special-shaped structures, the shape of the detection support 3 can be regular or irregular, other shapes, so that the entire detection support 3 can cover a wider range, facilitating detection. When the detection support 3 is installed, the number of mounting holes 11 is correspondingly provided according to the top points of each side of the detection support 3, which facilitates the insertion of the top points of each side of the detection support 3 into the corresponding mounting holes 11, and realizes the installation and fixation of the detection support 3.

[0031] In the following, the detection support 3 in Figure 2 is taken as an example for description, which is as follows:

[0032] The detection support 3 comprises a first support 31 and a second support 32, and the connecting wire 43 is two, which is respectively electrically connected with the first support 31 and the second support 32, and the first support 31 and the second support 32 are symmetrically arranged. Therefore, the through hole 411 on the connector 41 is also correspondingly two, which facilitates the fixation of the first support 31 and the second support 32, and the connection with the connecting wire 43.

[0033] The side wall of the heat insulation ring 1 is provided with three mounting holes 11.

[0034] The first support 31 comprises a first vertical part 311, a first inclined part 312, a second vertical part 313 and a second inclined part 314 connected in sequence, the first vertical part 311 is connected with the connecting wire 43 through the heat insulation ring 1, the first inclined part 312, the second vertical part 313 and the second inclined part 314 are all located in the heat insulation ring 1, the inclined directions of the first inclined part 312 and the second inclined part 314 are opposite, one end of the first vertical part 311 of the first support 31 and the second support 32 is respectively inserted into the corresponding mounting hole 11, and the two second inclined parts 312 are respectively inserted into the corresponding mounting hole 11. Wherein, each part of the first support 31 is an integral molding structure, and each part of the second support 32 is an integral molding structure, so that the molding processing of the support 3 can be conveniently detected. Therefore, by providing each corresponding inclined part and vertical part, the distribution range of the first support and the second support can be increased, which is beneficial to detecting the placement of the pot in all directions and improving the detection accuracy.

[0035] The first inclined part 312 is inclined to the side away from the second support 32, and the second inclined part 314 of the first support 31 intersects with the second inclined part 314 of the second support 32. Therefore, by setting the inclined directions of the first inclined part and the second inclined part, the distribution range of the detection support on the heat insulation ring can be further improved, and the distribution is more reasonable.

[0036] Wherein, the two mounting holes 11 near the connector 41 pass through the heat insulation ring 1, so that one end of the first support 31 and the second support 32 can be conveniently extended out of the corresponding mounting hole 11 and then extended to the connector 41. During installation, the other end of the first support 31 and the second support 32 is inserted into the corresponding mounting hole 11 in the side wall of the heat insulation ring 1, so that the installation and fixation of the entire detection support 3 on the heat insulation ring 1 is realized, the movement of the detection support 3 is prevented, and the stability during detection is ensured.

[0038] In actual use, the outer end of the second inclined part 314 abuts against the inner wall of the heat insulation ring 1, and the first support 31 and the second support 32 are extended from one side of the inner wall of the heat insulation ring 1 to the opposite side of the inner wall of the heat insulation ring 1, so that the distribution range of the entire detection support 3 is wider, the placement of the pot above the entire heating disc can be better detected, and the detection is more accurate.

[0039] The temperature detection device 5 is a thermocouple, and the thermocouple is located in the middle of the heat insulation ring 1 and extends to one side of the heating wire 2. Therefore, by providing the thermocouple, the heating temperature of the heating wire 2 can be detected, and the corresponding use requirements can be met.

[0040] Thus, the electric ceramic stove heating disc with pot detection of the utility model, through the connecting device 4, can conveniently detect the installation of the support 3 and the connection with the corresponding controller of the outside world; through the detection support 3, whether the pot is placed on the whole heating disc can be detected, when the pot is not placed, the heating wire 2 does not heat; when the pot is detected to be placed, the heating wire 2 heats again, thereby effectively avoiding the risk of touching the high-temperature heating area in the prior art, improving the safety during use and ensuring the use safety of the operator.

[0041] In actual use, the shape of the detection support 3 can be adjusted accordingly, one end of the first support 31 and the second support 32 respectively extends out to be close to the mounting hole 11 of the connector 41. The other end of the first support 31 and the second support 32 can be separated and respectively inserted into the other two mounting holes 11; the other end of the first support 31 and the second support 32 can also be close together, then only need to be inserted into a corresponding mounting hole 11.
