Therefore, in actual design, due to cost and space constraints, the number of temperature measuring elements is strictly controlled, which results in some areas becoming temperature measuring blind areas, making it impossible to achieve full coverage, thereby increasing the risk of panel breakage due to failure to timely detect and handle high-temperature points.

[0036] The technical scheme in the embodiments of the utility model will be clearly and completely described below by combining with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0037] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, if the certain posture changes, the directional indications also change accordingly.

Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, if "and / or" or "and / or" appears throughout the text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, also not within the protection scope required by the utility model.

[0039] Please refer to 1 to Figure 3 In the prior art, due to the internal structure of the electromagnetic oven, especially the existing electromagnetic coil structure 1', which is usually arranged in two layers of circular rings with a gap therebetween, the temperature measuring element 2' needs to be arranged in the gap between the coils and avoid the magnetic strip and other components installed at the bottom of the coil. Therefore, in actual design, due to the cost and space limitations, the number of temperature measuring elements 2' is strictly controlled, which leads to some areas becoming temperature measuring blind area a', which cannot be fully covered, thereby increasing the risk of panel rupture due to the failure to timely discover and handle high temperature points.

[0040] The utility model provides a kind of electromagnetic cooking utensil, to solve the problem that the temperature measuring blind area exists in the existing electromagnetic cooking utensil, and panel is prone to rupture due to the failure to timely discover high temperature point.

[0041] Please refer to Figures 4 to 9 In an embodiment of the utility model, the electromagnetic cooking utensil includes a bottom shell, a panel, an electromagnetic heating device 100 and a temperature measuring assembly 2, the panel is arranged at the upper end of the bottom shell;The electromagnetic heating device 100 is installed on the bottom shell, and the electromagnetic heating device 100 includes a mounting bracket and an electromagnetic coil structure 1 installed on the mounting bracket, the electromagnetic coil structure 1 has a plurality of arc-shaped protrusions 10 located at the circumference and arranged outward;The temperature measuring assembly 2 includes a plurality of first temperature measuring portions 21 abutting against the panel, and each first temperature measuring portion 21 is arranged on the inner side of the corresponding arc-shaped protrusion 10.

[0042] It should be noted that, in the electromagnetic heating pot, in order to ensure that the electromagnetic heating device 100 works normally, the pot containing iron or containing iron is used to work with the electromagnetic heating device 100, and the eddy current is induced in the pot through the changing magnetic field to generate resistance heat, so that the pot is rapidly heated. Therefore, the pot usually adopts a double-bottom pot, and the double-bottom pot is composed of multiple layers of materials to improve the heat conductivity, durability and heat convection performance. The general double-bottom structure includes a stainless steel outer layer, an aluminum intermediate layer and a stainless steel bottom layer. In the production or use process, if there is a hollow or incomplete contact between the double-bottom layer and the aluminum layer, the heat conduction will be uneven, and then a local overheating area will be generated.

[0043] It should also be noted that, in the related art, the temperature measuring element 2' is in abutment with the panel, and the temperature of the pot is indirectly measured by measuring the temperature of the panel. However, when the material properties of some panels are good in the vertical direction, but the heat conduction performance in the horizontal direction is poor, if the pot bottom exists uneven heating and local overheating, and the area exceeds the temperature range of the panel's high temperature resistance, and the area is just in the detection blind area of the temperature measuring element 2', the panel will have a risk of rupture.

[0044] In the technical scheme of the utility model, the electromagnetic heating device 100 is arranged in the bottom shell, the electromagnetic heating device 100 includes a mounting bracket and an electromagnetic coil structure 1 mounted on the mounting bracket, the electromagnetic coil structure 1 has a plurality of arc-shaped protrusions 10 located at the periphery and arranged outward, and the temperature measuring assembly 2 includes a plurality of first temperature measuring portions 21 in abutment with the panel. Each first temperature measuring portion 21 is arranged on the inner side of the corresponding arc-shaped protrusion 10. Since each first temperature measuring portion 21 is arranged on the inner side of the corresponding arc-shaped protrusion 10, the temperature in the corresponding circular area of the panel centered on the first temperature measuring portion 21 can be monitored. By arranging the electromagnetic coil structure 1 in the form of the arc-shaped protrusion 10, the heating area formed by electromagnetic induction also presents an arc shape. Therefore, the circular area that can be detected by the plurality of first temperature measuring portions 21 covers and matches a plurality of arc-shaped heating areas, and the temperature of the corresponding arc-shaped heating area can be accurately monitored, so that the temperature control during the entire heating process is more accurate, thereby reducing the risk of panel rupture caused by local overheating due to the heating area formed by the electromagnetic coil structure 1 and the pot electromagnetic induction exceeding the detection range of the temperature measuring portion and forming a detection blind area.

[0045] It can be understood that the specific structure of the electromagnetic coil structure 1 has various forms, such as being composed of multiple independent small coils, and the multiple coils can work independently or cooperatively; it can also be an overall structure with a special shape (such as petal shape), so that the coil has several outwardly protruding parts; it can also be a combined electromagnetic coil, that is, a combination of a central large coil plus several small coils or petal-shaped segmented coils around it. The specific form of the electromagnetic coil structure 1 is not limited to the above examples, and other changes can be made by those skilled in the art under the inspiration of the technical essence of the embodiments of the present application, as long as the functions and effects achieved are the same or similar to those of the embodiments of the present application, which should be covered within the protection scope of the embodiments of the present application.

[0046] Further, please continue to refer to Figures 4 to 9 In some embodiments, the first temperature measuring part 21 is arranged at the center of the arc-shaped protruding part 10.

[0047] Since each of the first temperature measuring parts 21 is placed at the center of the arc-shaped protruding part 10 corresponding thereto. Since the heating area generated by the arc-shaped protruding part 10 of the electromagnetic coil structure 1 also expands outwardly with the arc-shaped protruding part 10 as the center, by placing the first temperature measuring part 21 at the center corresponding to the arc-shaped protruding part 10, the temperature change detected by the first temperature measuring part 21 can accurately reflect the actual temperature condition of the heating area corresponding to the arc-shaped protruding part 10.

[0048] It can be understood that the detection area of the first temperature measuring part 21 is circular, which matches the shape of the heating area corresponding to the arc-shaped protruding part 10. When the electromagnetic coil structure 1 is heated, since the shape and size of the detection area of the first temperature measuring part 21 and the heating area corresponding to the arc-shaped protruding part 10 are coordinated and consistent, the detection range of the first temperature measuring part 21 exactly covers the main heating area generated by the arc-shaped protruding part 10, thereby realizing efficient and accurate temperature monitoring.

[0049] Please refer to Figures 4 to 6 In the first embodiment, the electromagnetic coil structure 1 includes multiple first electromagnetic coils 11, and the multiple first electromagnetic coils 11 are arranged along the circumference of the mounting bracket, and the multiple first electromagnetic coils 11 are arranged close to one side of the circumference of the mounting bracket to form the arc-shaped protruding part 10.

[0050] It can be understood that the electromagnetic coil structure 1 is arranged along the circular edge (i.e. the circumference) of the mounting bracket by multiple independent first electromagnetic coils 11. When viewed from the top, the multiple first electromagnetic coils 11 present an outwardly protruding arc-shaped structure at the position close to the edge of the mounting bracket to form the arc-shaped protruding part 10.

[0051] The first electromagnetic coils 11 can be controlled individually or in combination according to actual needs, so as to achieve precise heating of different areas. Therefore, the number of the first electromagnetic coils 11 in operation and the location of the first electromagnetic coils 11 in operation can be adjusted according to the size of the pot placed on the panel. For example, for a small milk pot, only one first electromagnetic coil 11 needs to be controlled; for a large soup pot or frying pan, multiple first electromagnetic coils 11 can be controlled to cover a larger area.

[0052] By locating the first temperature measuring part 21 at the center of each independent first electromagnetic coil 11, each corresponding first temperature measuring part 21 can more accurately monitor the temperature change of a specific area, facilitating temperature adjustment and reducing the risk of temperature fluctuations.

[0053] Specifically, in this embodiment, the diameter of the first electromagnetic coil 11 is D, and 30mm≤D≤80mm.

[0054] The diameter of the first electromagnetic coil 11 is between 30mm and 80mm to ensure that the heat generated by the first electromagnetic coil 11 can be effectively monitored by the corresponding first temperature measuring part 21. If the diameter of the first electromagnetic coil 11 is too large, greater than 80mm, it exceeds the effective detection range of the first temperature measuring part 21, resulting in a temperature monitoring blind area in part of the area; if the diameter of the first electromagnetic coil 11 is too small, less than 30mm, more first electromagnetic coils 11 need to be set to cover the entire heating area to achieve the required heating range of the user. For the first temperature measuring part 21, two adjacent first temperature measuring parts 21 detect overlapping areas, which is redundant.

[0055] It can be understood that since the bottom of the pot is the main cooking and heating point, especially for some applications that require concentrated heating (such as boiling, rapid heating, etc.), the heating efficiency and temperature control of the central area are more important.

[0056] Further, in this embodiment, the electromagnetic coil structure 1 further comprises a second electromagnetic coil 12, and the plurality of first electromagnetic coils 11 are arranged around the periphery of the second electromagnetic coil 12; the temperature measuring assembly 2 further comprises a second temperature measuring part 22, and the second temperature measuring part 22 is arranged at the center of the second electromagnetic coil 12.

[0057] Therefore, the second electromagnetic coil 12 is located at the center of the electromagnetic coil structure 1, which can be used to heat the central area of the pot, ensuring that this area can obtain sufficient heat. Moreover, the second temperature measuring part 22 is arranged at the middle of the second electromagnetic coil 12, i.e., the position corresponding to the center of the bottom of the pot. In this way, the second temperature measuring part 22 can directly and accurately detect the actual temperature of the central area of the pot.

[0058] In addition to the circumferential direction, the first temperature measuring part 21 can realize multi-point temperature measurement. The second temperature measuring part 22 increases the detection points and more comprehensively monitors more detection points, thereby reducing the risk of local overheating.

[0059] Specifically, please refer to Figures 7 to 9 In the second embodiment, the electromagnetic coil structure 1 further comprises a third electromagnetic coil 13, which is arranged in a ring shape along the circumferential direction of the bracket, and the periphery thereof partially protrudes outward to form the arc-shaped protruding part 10.

[0060] It can be understood that the third electromagnetic coil 13 is a complete coil, and the arc-shaped protruding part 10 is formed by partially protruding the periphery of the third electromagnetic coil 13 outward. The two arc-shaped protruding parts 10 arranged adjacently are connected by an arc-shaped recess. Therefore, continuous heating in the circumferential direction of the mounting bracket can be realized. Therefore, for the application scenario in which the heating of the edge of the pot needs to be strengthened, the third electromagnetic coil 13 is more suitable.

[0061] It should be further pointed out that by reasonably setting the shape of the third electromagnetic coil 13, such as the position and size of the arc-shaped protruding part 10, the heat distribution can be better controlled, and the entire pot bottom can be ensured to obtain more uniform heating effect, thereby avoiding the problem of uneven food cooking caused by overheating or insufficient heating in some areas.

[0062] Compared with arranging multiple independent first electromagnetic coils 11, the third electromagnetic coil 13 can simplify the overall design, reduce the number of parts, and thus reduce the production cost and assembly difficulty.

[0063] Since the two arc-shaped protruding parts 10 arranged adjacently are connected by an arc-shaped recess, each first temperature measuring part 21 can cover the heating area corresponding to the arc-shaped protruding part 10, and the area corresponding to the arc-shaped recess can also cover most of the area. Therefore, compared with the prior art, the arrangement form provided in the embodiment can also reduce the detection blind area as much as possible.

[0064] Further, in this embodiment, the electromagnetic coil structure 1 further comprises a fourth electromagnetic coil 14, and the third electromagnetic coil 13 is arranged around the fourth electromagnetic coil 14; the temperature measuring assembly 2 further comprises a third temperature measuring part 23, and the third temperature measuring part 23 is arranged at the middle part of the fourth electromagnetic coil 14.

[0065] Similarly, the fourth electromagnetic coil 14 is arranged at the center of the electromagnetic coil structure 1, so as to ensure that sufficient heat can be provided when the central area of the pot is heated.

[0066] The third temperature measuring part 23 is arranged at the middle part of the fourth electromagnetic coil 14, so as to directly and accurately detect the actual temperature of the central area of the pot, thereby more comprehensively monitoring more detection points and reducing the risk degree of local overheating.

[0067] Further, in this embodiment, the first temperature measuring part 21 is elastically abutted against the panel.

[0068] The "elastically abutting" means that the first temperature measuring part 21 can be mounted on the bottom shell through an elastic member, and the elastic member can be a spring, a rubber member or a silica gel member, and of course other possible structures can also be adopted, and the specific structure can be determined according to the actual situation, and the embodiment of the present application does not limit the same.

[0069] During the use of the electromagnetic cooking utensil, the panel will expand due to heating or deform due to changes in the external environment, and by elastically abutting the first temperature measuring part 21 against the panel, the first temperature measuring part 21 can adapt to the slight changes of the panel, and the contact pressure between the first temperature measuring part 21 and the panel can be flexibly adjusted, so as to always maintain the close contact degree, reduce the thermal resistance in the heat conduction process, ensure that the heat can be quickly and effectively transferred to the first temperature measuring part 21, so that the first temperature measuring part 21 can sense the temperature change of the panel in real time, and avoid the temperature measurement error caused by poor contact.

[0070] Specifically, in this embodiment, the temperature measuring assembly 2 further comprises an elastic support 24, and the first temperature measuring part 21 is mounted on the mounting support through the elastic support 24.

[0071] It should be noted that the elastic support 24 can be a support made of a material with elastic characteristics, and the elastic support 24 serves as a mounting and connecting part on one hand and provides elasticity on the other hand, thereby reducing the number of components and reducing the production cost.

[0072] Specifically, the elastic support 24 can be made of silica gel material, which has good elasticity and flexibility and can adapt to different shapes and sizes. In addition, silica gel is generally resistant to high temperature and suitable for use in high temperature environments.

[0073] It should be noted that the elastic support 24 is used for mounting the first temperature measuring part 21, and the structures of the plurality of elastic supports 24 can be the same or different. The elastic support 24 can be designed in terms of structure, quantity and form according to the actual mounting support and the position of the first temperature measuring part 21 required to measure the temperature.

[0074] Specifically, in the embodiment, the panel includes a high borosilicate glass panel.

[0075] It should be noted that high borosilicate glass is a kind of glass containing boron oxide (B2O3) component, which has good high temperature resistance and can withstand temperature changes. The surface of high borosilicate glass is smooth and easy to clean, and oil stains and food residues are not easy to adhere.

[0076] In related technologies, the panel uses a microcrystalline glass panel, but the production and raw materials of microcrystalline glass have high cost. High borosilicate glass has good performance, but when the pot appears a special abnormal continuous heating unevenness, the risk of high borosilicate glass breaking is slightly greater than that of microcrystalline glass panel, so the cost is relatively low.

[0077] By providing the plurality of first temperature measuring parts 21, the abnormal condition of the pot can be detected in time, so that the panel does not exist the condition of abnormal high temperature continuous generation, and therefore the use of high borosilicate glass material can greatly reduce the production cost.

[0078] In the embodiment, the first temperature measuring part 21 includes a thermistor.

[0079] It should be noted that the resistance value of the thermistor changes significantly with temperature. The thermistor includes NTC (negative temperature coefficient) thermistor and PTC (positive temperature coefficient) thermistor. By measuring the resistance value of the thermistor, the current temperature can be indirectly calculated.

[0080] Because the thermistor is very sensitive to temperature changes, compared with other temperature sensors, the thermistor can provide higher measurement accuracy in a specific temperature range, and is suitable for cooking scenes such as frying and frying. The thermistor has small volume and is easy to integrate on the mounting support, and does not occupy too much space, so the thermistor is selected as the temperature measuring element, which is suitable for the use scene and the structure characteristics of the electromagnetic cooking utensil.

[0081] It also needs to be explained that the temperature measuring assembly 2 includes the second temperature measuring part 22 and the third temperature measuring part 23, and the second temperature measuring part 22 and the third temperature measuring part 23 can be set as thermistors, of course, can also be set as other forms of temperature measuring elements, and the specific can be determined according to the actual situation, and the embodiment of the present application is not limited.

[0082] The above is only an exemplary embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
