[0003] To this end, technicians in this field have devoted themselves to researching electric ceramic stoves with anti-dry burning function, for example, by weighing to determine the amount of water evaporation, and then determine whether it is dry burning. However, when using this method to determine, the weight parameter must be reset every time a heating container is changed, the operation is complicated and not easily widely accepted by users.

DETAILED DESCRIPTION

[0023] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present embodiment provides an anti-burn-dry electric ceramic stove, including a stove body, which specifically includes a microcrystalline panel 1 and a heating plate 2 arranged up and down and bolted together, a heating wire is arranged on the top of the heating plate 2, and the heating wire heats the microcrystalline panel 1 after being energized, so that the microcrystalline panel 1 is heated to evenly heat the pot placed on the microcrystalline panel 1.

[0027] The anti-dry-burn electric ceramic stove of this embodiment also includes a temperature measuring device, which is used to detect the temperature of the bottom of the pot, so as to facilitate the judgment of whether the pot is in a dry-burning state. Under normal circumstances, when the electric ceramic stove is working, the working temperature of the surface of the microcrystalline panel 1 is about 600°C, and the temperature of the bottom of the pot in contact with it will fluctuate between 250°C and 350°C depending on the different materials. When the water in the pot is gradually dried up, the temperature of the bottom of the pot will gradually rise. When the temperature rises to 400°C, it can be determined that the pot is in a dry-burning state. Therefore, as long as the temperature of the bottom of the pot can be monitored in real time, it is possible to accurately judge whether the pot is in a dry-burning state by the change in temperature.

[0028] The temperature measuring device includes a mounting seat 3, which is connected to the stove body. Specifically, the mounting seat 3 includes a sleeve 31, the top of the sleeve 31 is protruding outwardly provided with a baffle 311, and the inner circumference of the sleeve 31 is provided with a mounting hole 312. A countersunk hole 11 with a larger top and a smaller bottom is provided in the middle of the microcrystalline panel 1, the sleeve 31 is inserted into the countersunk hole 11, and the baffle 311 abuts against the step surface of the countersunk hole 11. The mounting seat 3 also includes a nut 32, which is threadedly connected to the outer circumference of the sleeve 31 to limit the axial relative position of the sleeve 31 and the stove body. In this embodiment, the nut 32 is specifically located between the microcrystalline panel 1 and the heating plate 2, so that the microcrystalline panel 1 is sandwiched between the nut 32 and the baffle 311, so as to achieve a fixed connection between the mounting seat 3 and the stove body.

[0029] The temperature measuring device further comprises a telescopic member 4, which is slidably assembled in the mounting hole 312. A thermocouple 5 is penetrated through the inner periphery of the telescopic member 4, and a limiting structure for limiting the axial position of the thermocouple 5 is also provided on the telescopic member 4. The top of the thermocouple 5 extends out of the telescopic member 4, and an elastic member 6 is provided between the telescopic member 4 and the mounting seat 3. The telescopic member 4 can slide relative to the mounting seat 3 under the action of an axial external force. When the telescopic member 4 is not subject to an axial external force, the top of the thermocouple 5 is higher than the top of the microcrystalline panel 1. In this embodiment, the thermocouple 5 extends out from the top of the microcrystalline panel 1 when not affected by external force. After the cookware is placed on the top of the microcrystalline panel 1, the thermocouple 5 will move downward under the action of the gravity of the cookware until the cookware is stably placed on the top of the microcrystalline panel 1. The design of this telescopic thermocouple can adapt to cookware with bottom surfaces of different flatnesses, so that cookware with bottom surfaces of various shapes can be stably placed on the microcrystalline panel 1. At the same time, the bottom of the cookware can also maintain contact with the thermocouple 5, and the design of the elastic member 6 makes the thermocouple 5 have a tendency to move upward, so that the thermocouple 5 can be in close contact with the bottom of the cookware, ensuring that the temperature measurement of the thermocouple 5 is reliable.

[0030] Specifically, the telescopic member 4 includes a limiting sleeve 41 and a connecting member 42 which are sleeved on the outer periphery of the thermocouple 5, and the limiting sleeve 41 is located above the connecting member 42. The connecting member 42 includes a limiting portion 421 and a connecting portion 422, the limiting portion 421 abuts against the bottom of the sleeve 31, the connecting portion 422 is penetrated in the mounting hole 312 and is threadedly connected to the limiting sleeve 41, and a threaded hole 411 threadedly connected to the connecting portion 422 is provided at the bottom of the limiting sleeve 41.

[0031] The mounting hole 312 is a countersunk hole with a larger top and a smaller bottom. The elastic member 6 is a compression spring. The elastic member 6 is sleeved on the outer periphery of the connecting portion 422 , and the elastic member 6 is compressed and abutted between the bottom of the limiting sleeve 41 and the step surface of the mounting hole 312 .

[0032] In this embodiment, the limiting portion 421 cooperates with the bottom of the sleeve 31 to form an upper limit to limit the maximum extension position of the telescopic member 4 relative to the mounting seat 3, and the bottom of the limiting sleeve 41 cooperates with the step surface of the mounting hole 312 to form a lower limit to limit the maximum retracted position of the telescopic member 4 relative to the mounting seat 3, so as to prevent the telescopic member 4 from falling downward out of the mounting hole 312.

[0033] Furthermore, a limiting structure for limiting the axial position of the thermocouple 5 is provided on the limiting sleeve 41, and the limiting structure includes a fastening hole 412 provided on the limiting sleeve 41 along the radial direction, and a fastener (not shown in the figure) is connected to the inner thread of the fastening hole 412. In this embodiment, the fastener is a set screw, which can be tightened under the action of an external force and tightly abut against the outer surface of the thermocouple 5, thereby locking the thermocouple 5, preventing the axial relative movement between the thermocouple 5 and the telescopic member 4, and thus enabling the thermocouple 5 to move synchronously with the telescopic member 4.

[0034] The anti-dry-burn electric ceramic stove of this embodiment can judge whether the pot is in a dry-burning state according to the change of the bottom temperature of the pot fed back by the thermocouple 5. The judgment process is more real and reliable, and the user does not need to set parameters, which is easy to operate. In practice, when the control system of the electric ceramic stove judges that the pot is in a dry-burning state, it can start the protection action to cut off the heating function, so that the electric ceramic stove is in a power-off standby state.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
