Simultaneously, Chinese Patent Publication No. CN119164509A also discloses a cooking appliance and its temperature detection method. The cooking appliance includes a first thermocouple and a heating coil; the temperature detection method involves controlling the heating coil to work and simultaneously heating the first thermocouple when the cooking appliance is started; after heating the first thermocouple for a first preset time, obtaining the actual temperature of the first thermocouple; when the actual temperature of the first thermocouple is greater than or equal to the preset temperature, controlling the heating coil to stop working and stopping heating the first thermocouple; this application can effectively alleviate the low temperature detection sensitivity of current cooking appliances.

[0004] In other words, in existing electric ceramic stoves, in addition to relying on the main control unit to control the heating of the inner and outer heating wires and the temperature detection of thermocouples (temperature detection unit, temperature protection device), it is also necessary to ensure the stability of the power supply unit, that is, the connection stability between the inner and outer heating wires and the power supply line. This connection stability is reflected in the structural improvement on the one hand, and the processing process needs to be improved on the other hand, so as to improve the accuracy and efficiency of assembly while meeting the connection stability.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] The direct-insertion type electric ceramic stove described in this application includes a metal bottom shell. An insulating ring and an insulating base are disposed inside the metal bottom shell. A heating element is arranged within the space formed by the insulating ring and the insulating base. Two connection ports of the heating element are respectively connected to a branch terminal and a common terminal.

[0019] The technical solutions described in this application will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, a direct-plug type electric ceramic stove includes a metal bottom shell 4, the inner bottom surface of which is covered with a heat-insulating base 7, and a heat-insulating ring 6 that is higher than the top of the metal bottom shell 4 is provided in the circumferential direction. The top of the heat-insulating ring 6 is in contact with the glass of the whole machine, and the bottom of the heat-insulating ring 6 is connected to the heat-insulating base 7.

[0022] A heating element 5 is installed within the space formed by the heat insulation ring 6 and the heat insulation base 7. The heating element 5 can be a heating plate made of heating wire. The heating element 5 includes two electrically connected ports, one of which is connected to a corresponding branch terminal 2, and the other is electrically connected to a common terminal 10. Both the branch terminal 2 and the common terminal 10 are inserted and fixed in corresponding terminal insertion slots 12. The terminal insertion slots 12 on the terminal connecting ceramic 1 are also used to connect corresponding protective terminals 11. The common terminal 10 and the protective terminal 11 are respectively connected to the output and input terminals of the temperature protection device 3. The temperature protection device 3 also includes a temperature sensor 8, which is located within the space formed by the heat insulation ring 6 and the heat insulation base 7.

[0023] Example 2

[0024] See also Figures 1 to 4A direct-insertion type electric ceramic stove, wherein the temperature sensor 8 is connected to the heat-insulating base 7 via a sensor support 9, and the top of the terminal insertion slot 12 is flush with the top of the heat-insulating ring 6. Multiple heating elements 5 are evenly distributed on the heat-insulating base 7, each heating element 5 has one connection port electrically connected to a corresponding branch terminal 2, and the other connection port of each heating element 5 is electrically connected to the same common terminal 10.

[0025] The structure and connections of the remaining parts are the same as those described in the previous embodiment, and will not be repeated here to avoid redundancy. Those skilled in the art can understand the technical solution described in this embodiment based on the foregoing embodiments.

[0026] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0027] In this application, the terminal connection ceramic 1 includes a plurality of terminal insertion slots 12 for processing. These slots are used to insert and fix corresponding branch terminals 2, common terminals 10, and protection terminals 11. The number of terminal insertion slots 12 is determined based on the number of branch terminals 2, common terminals 10, and protection terminals 11, to achieve fast and accurate power connection. The terminal connection ceramic 1 is connected to the insertion end of a power cord. The insertion end of the power cord has insertion holes corresponding to different terminals. The power cord is inserted into different terminals through these insertion holes, achieving an effective and stable electrical connection. (See the appendix of this application.) Figure 1 As shown, different numerical markings can be provided on the terminal connecting ceramic 1 at the positions corresponding to the terminal insertion slots 12 to clearly identify the insertion and fixing positions of different terminals. The terminal connecting ceramic 1 can be integrally formed with the metal base shell 4 or connected as an integral unit by fasteners.

[0028] In this application, the branch terminal 2 is used to achieve electrical connection with one of the connection ports of the corresponding heating element 5. When there are multiple heating elements 5, there are also multiple branch terminals 2, and their number can be the same as the number of heating elements 5.

[0029] In this application, the temperature protection device 3 is a temperature control device, which is fixed to the metal base 4 by fasteners and uses a temperature sensor 8 to sense the temperature of the heating element 5 within the space formed by the heat insulation ring 6 and the heat insulation base 7. When the temperature in this space is too high, the temperature protection device 3 will disconnect the electrical connection between the common terminal 10 and the protection terminal 11, thereby protecting the overall structure and preventing damage caused by overheating of the heating plate.

[0030] In this application, the metal base shell 4 constitutes the base space of the electric ceramic stove, and a heat-insulating base 7 is laid on the inner bottom surface of the metal base shell 4. The heat-insulating base 7 is used to isolate the heat generated by the heating element 5 and also to prevent the metal base shell 4 from conducting electricity, ensuring electrical safety. A heat-insulating ring 6 is provided at the circumferential edge of the metal base shell 4, and the bottom end of the heat-insulating ring 6 and the heat-insulating base 7 can form an integral structure, thereby achieving thermal and electrical isolation of the internal space of the metal base shell 4.

[0031] In this application, the top of the heat insulation ring 6 is also attached to the microcrystalline glass of the electric ceramic stove, and the heat generated by the heating element 5 can be transferred to the cookware through the microcrystalline glass.

[0032] Apart from the improved structure described above, the structure of the rest of the parts is the same as that of the existing electric ceramic stove.

[0033] Finally, although the technical solutions described in this application are based on the preferred embodiments, those skilled in the art can recombine the technical solutions described in this application based on their prior art. Such recombination should be understood as still within the protection scope of this application and protected by this application.
