The heating assembly is arranged around the first temperature detection piece; and the at least two second temperature detection pieces are arranged in the heating assembly and / or on the outer side of the heating assembly, and the second temperature detection pieces are used for detecting the temperature of the heating assembly. According to the heating device, due to the fact that the number of the second temperature detection pieces is at least two, even if part of the second temperature detection pieces are interfered by the cookware, the other part of the second temperature detection pieces can accurately detect the temperature of the heating assembly, and even if all the second temperature detection pieces are interfered by the cookware, the temperature of the heating assembly can be accurately detected.

Description

TECHNICAL FIELD

[0001] The utility model relates to cooking equipment technical field, specifically to a kind of heating device and cooking equipment. BACKGROUND

[0002] In related art, for coil disc type heating device, usually only one thermocouple is arranged at the center of coil disc for testing the temperature of winding of coil disc, when the temperature of winding reaches the use temperature limit, power is reduced to handle, so that the temperature of winding is maintained at use temperature limit.

[0003] However, when the pot covers the temperature measuring thermocouple arranged at the center of coil disc, the thermocouple cannot accurately measure the area of the highest temperature of the winding, which may cause the risk of damage to the heating device. SUMMARY

[0004] The utility model aims at at least solving or improving the technical problem that the temperature detection member on the heating device in the prior art cannot accurately detect the temperature of the heating assembly.

[0005] Therefore, the first aspect of the utility model provides a kind of heating device.

[0006] The second aspect of the utility model provides a kind of cooking equipment.

[0007] Therefore, according to the first aspect of the utility model, the utility model provides a kind of heating device, comprising: a first temperature detection member; heating assembly, which is arranged around the first temperature detection member; at least two second temperature detection members, which are arranged in the heating assembly and / or outside the second heating assembly, and are used for detecting the temperature of the heating assembly.

[0008] The heating device provided by the utility model comprises a first temperature detection member and a heating assembly, and the heating assembly is arranged around the first temperature detection member, so that the heating assembly can heat the pot.

[0009] In addition, the heating device further comprises a second temperature detection member, and the number of the second temperature detection member is at least two, and the at least two second temperature detection members are arranged in the heating assembly and / or outside the heating assembly, so as to detect the temperature of the heating assembly.

[0010] In addition, the heating device according to the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0011] In some embodiments, optionally, the number of second temperature sensors is at least three, and the at least three second temperature sensors are disposed on the outside of the heating assembly.

[0012] In this embodiment, the number of second temperature detection elements is at least three. The at least three second temperature detection elements are arranged on the outside of the heating assembly. Since the heating assembly has a large area, using at least three second temperature detection elements to detect its temperature reduces the possibility that all the second temperature detection elements will be affected by the cookware, thereby improving the accuracy of temperature detection of the heating assembly.

[0013] In some embodiments, optionally, at least three second temperature sensing elements are evenly distributed on the outside of the heating assembly.

[0014] In this embodiment, at least three second temperature sensors are evenly distributed on the outside of the heating assembly, thereby further reducing the possibility that all the second temperature sensors are affected by the cookware and improving the accuracy of temperature detection of the heating assembly.

[0015] In some embodiments, the heating assembly may optionally include: a first heating assembly disposed around a first temperature sensing element; and a second heating assembly disposed around the first heating assembly; wherein at least one second temperature sensing element is disposed between the first heating assembly and the second heating assembly, and at least one second temperature sensing element is disposed outside the second heating assembly.

[0016] In this embodiment, the heating assembly includes a first heating assembly and a second heating assembly. The first heating assembly is disposed around a first temperature sensing element, and the second heating assembly is disposed around the first heating assembly. The first heating assembly and the second heating assembly are spaced apart to provide installation space for the second temperature sensing element. At least one second temperature sensing element is disposed between the first heating assembly and the second heating assembly, and at least one second temperature sensing element is disposed outside the second heating assembly. This allows the second temperature sensing element to detect the temperature of the first heating assembly and / or the second heating assembly at multiple locations. Even if some of the second temperature sensing elements are affected by the cookware, another second temperature sensing element can still accurately detect the temperature of the first heating assembly and / or the second heating assembly.

[0017] In some embodiments, optionally, the number of second temperature sensors is two, with the first temperature sensor located between the two second temperature sensors.

[0018] In this embodiment, there are two second temperature sensors, with the first temperature sensor located between the two second temperature sensors. This reduces the number of second temperature sensors, lowers production costs, and increases the distance between the two second temperature sensors, reducing the possibility that both second temperature sensors will be affected by the cookware at the same time.

[0019] In some embodiments, optionally, with the first temperature sensor as the vertex, the included angle formed by the first temperature sensor and the two second temperature sensors is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0020] In this embodiment, with the first temperature sensor as the vertex, the angle formed by the first temperature sensor and the two second temperature sensors is greater than or equal to 90 degrees and less than or equal to 180 degrees, thereby ensuring that the distance between the two first temperature sensors is relatively large, further reducing the possibility that the two second temperature sensors will be affected by the cookware at the same time.

[0021] In some embodiments, the first temperature sensing element is optionally a thermistor; the second temperature sensing element is a thermocouple.

[0022] In this embodiment, the first temperature detection element is a thermistor, which has high sensitivity and can better detect the temperature of the cookware. The second temperature detection element is a thermocouple, which has high reliability, thereby improving the accuracy of temperature detection of the heating component.

[0023] In some embodiments, the heating element may be a heating coil wound in a circular shape.

[0024] In this embodiment, the heating element is a heating coil, which is wound in a circular shape to obtain a circular heating element. The circular heating element can better adapt to the cookware.

[0025] In some embodiments, optionally, the heating element further includes: a heat insulation layer disposed on one side of the heating assembly, the heat insulation layer having at least three through holes, and a first temperature sensing element and a second temperature sensing element being disposed corresponding to the through holes.

[0026] In this embodiment, the heating device further includes a heat insulation layer disposed on one side of the heating component, and at least three through holes are provided corresponding to the first temperature detection element and the second temperature detection element. One through hole corresponds to the first temperature detection element, and at least two through holes correspond to at least two second temperature detection elements. The heat insulation layer reduces the impact of the heating component on other components of the heating device.

[0027] In some embodiments, the insulation layer may optionally have a boss, a first temperature sensor disposed on the boss, and a second temperature sensor located outside the boss.

[0028] In this embodiment, the heat insulation layer has a boss, and a first temperature detection element is disposed on the boss to better detect the temperature of the cookware. A second temperature detection element is located outside the boss and is farther away from the cookware, so it can better detect the temperature of the heating element.

[0029] According to a second aspect of the present invention, a cooking device is provided, comprising: a heating device as described in the first aspect embodiment.

[0030] The cooking device proposed in this utility model includes the heating device as described in the first aspect embodiment, and therefore has all the beneficial effects of the heating device as described in the first aspect embodiment, which will not be described in detail here.

[0050] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0052] The following reference Figures 1 to 15 This invention describes a heating device 100 and a cooking apparatus provided according to some embodiments of the present invention.

[0053] like Figure 1 andFigure 8 As shown, according to a first aspect of the present invention, the present invention provides a heating device 100, comprising: a first temperature detection element 110, a heating assembly 120, and a second temperature detection element 130. The heating assembly 120 is arranged around the first temperature detection element 110. The number of second temperature detection elements 130 is at least two. The at least two second temperature detection elements 130 are arranged in the heating assembly 120 and / or on the outside of the second heating assembly 120, thereby realizing the detection of the temperature of the heating assembly 120 through the second temperature detection elements 130.

[0054] The heating device 100 provided by this utility model includes a first temperature detection element 110 and a heating component 120. The heating component 120 is arranged around the first temperature detection element 110 and can heat the cookware.

[0055] Furthermore, the heating device 100 also includes a second temperature detection element 130. The number of second temperature detection elements 130 is at least two. The at least two second temperature detection elements 130 are respectively disposed in the heating component 120 and / or on the outside of the heating component 120, thereby realizing the detection of the temperature of the heating component 120. Since there are at least two second temperature detection elements 130, even if some second temperature detection elements 130 are interfered with by the pot, there are still other second temperature detection elements 130 that can accurately detect the temperature of the heating component 120. Even if all the second temperature detection elements 130 are interfered with by the pot, the large number of second temperature detection elements 130 allows for detection at multiple locations, thereby reflecting the current temperature status of the heating component 120, improving the accuracy of temperature detection of the heating component 120, and reducing the possibility of damage to the heating device 100.

[0056] The heating component 120 has both electromagnetic heating and infrared heating functions. That is, the heating component 120 can be heated by electromagnetic heating, infrared heating, or both simultaneously. Furthermore, by setting multiple second temperature detectors 130, it is ensured that even when the pot is offset relative to the heating component 120, the second temperature detectors 130 can still measure the maximum temperature of the heating component 120, thus ensuring the normal operation of the heating component 120.

[0057] Specifically, the first temperature detector 110 can be used to detect the temperature of a pot placed on the heating device 100 for heating, and the second temperature detector 130 can be used to detect the temperature of the heating assembly 120.

[0058] like Figure 1As shown, in some embodiments, optionally, the number of second temperature sensors 130 is at least three, and at least three second temperature sensors 130 are disposed on the outside of the heating assembly 120.

[0059] In this embodiment, the number of second temperature detection elements 130 is at least three. At least three second temperature detection elements 130 are arranged on the outside of the heating assembly 120. Since the heating assembly 120 has a large area, at least three second temperature detection elements 130 are used to detect its temperature, which reduces the possibility that all the second temperature detection elements 130 are affected by the cookware and improves the accuracy of temperature detection of the heating assembly 120.

[0060] The number of the second temperature detection elements 130 can be three, four, five, six, or seven, etc.

[0061] like Figure 1 As shown, in some embodiments, optionally, at least three second temperature sensing elements 130 are evenly distributed on the outside of the heating assembly 120.

[0062] In this embodiment, at least three second temperature sensors 130 are evenly distributed on the outside of the heating assembly 120, thereby further reducing the possibility that all the second temperature sensors 130 are affected by the cookware and improving the accuracy of temperature detection of the heating assembly 120.

[0063] Of course, in other embodiments of this application, at least three second temperature sensing elements 130 may also be unevenly distributed on the outside of the heating assembly 120.

[0064] Specifically, such as Figure 3 As shown, if the pot is large enough and placed in the center of the heating element 120, covering both the heating element 120 and the three second temperature sensors 130, the heating element 120 exchanges heat with the pot quickly, resulting in uniform temperature distribution. All three second temperature sensors 130 can detect the temperature of the heating element 120 and determine whether to reduce its power. For example, if the temperature of the heating element 120 reaches a preset temperature threshold, its power is reduced; if the temperature is below the preset temperature threshold, its power is not reduced. The preset temperature threshold can be the operating limit temperature of the heating element 120, or a temperature slightly lower than its operating limit temperature.

[0065] like Figure 4As shown, the area covered by cookware 1 or cookware 2 does not have the second temperature detection element 130, that is, the second temperature detection element 130 is not covered by cookware 1 or cookware 2. At this time, the temperature of the heating element 120 outside the area covered by cookware 1 or cookware 2 is higher than the temperature within the area covered by cookware 1 or cookware 2. However, all three second temperature detection elements 130 can detect the temperature of the heating element 120 outside the area covered by cookware 1 or cookware 2. One of the second temperature detection elements 130 detects that the temperature of the heating element 120 exceeds the preset temperature threshold T0, that is, reduces the power of the heating element 120 so that the maximum temperature of the heating element 120 remains below the preset temperature threshold T0.

[0066] like Figure 5 As shown, the area covered by the cookware has only one second temperature detection element 130, and two second temperature detection elements 130 are located outside the area covered by the cookware. Among them, one of the two second temperature detection elements 130 located outside the area covered by the cookware detects that the temperature of the heating element 120 exceeds the preset temperature threshold T0, that is, reduces the power of the heating element 120 so that the maximum temperature of the heating element 120 is kept below the preset temperature threshold T0.

[0067] like Figure 6 As shown, there are two second temperature detection elements 130 in the area covered by the cookware. One second temperature detection element 130 is located outside the area covered by the cookware. When the second temperature detection element 130 outside the area covered by the cookware detects that the temperature of the heating element 120 exceeds the preset temperature threshold T0, it reduces the power of the heating element 120 so that the maximum temperature of the heating element 120 remains below the preset temperature threshold T0.

[0068] like Figure 7 As shown, the area covered by the cookware has three second temperature sensors 130, but they do not completely cover all heating elements 120. At this time, the temperature of the heating elements 120 outside the area covered by the cookware is higher than the temperature of the heating elements 120 within the area covered by the cookware. However, the heating elements 120 outside the area covered by the cookware are only at the edge of the heating elements 120. Therefore, the temperatures of the three second temperature sensors 130 and the edge of the heating elements 120 will be similar. Thus, the temperature of the second temperature sensors 130 can be regarded as the highest temperature of the heating elements 120. This method has a low risk of damage to the heating elements 120.

[0069] As mentioned above, when the cookware is arbitrarily offset, the three second temperature detection elements 130 can basically cover various cookware offset states and can identify the highest temperature state of the heating element 120. This is used to determine the highest temperature of the heating element 120, and it can be used to determine whether the heating element 120 needs to reduce its power.

[0070] like Figure 1 and Figure 8As shown, in some embodiments, optionally, the heating component 120 includes a first heating component 122 and a second heating component 124, the first heating component 122 being disposed around the first temperature sensing element 110, and the second heating component 124 being disposed around the first heating component 122.

[0071] In this embodiment, the heating component 120 includes a first heating component 122 and a second heating component 124. The first heating component 122 is arranged around the first temperature detection element 110, and the second heating component 124 is arranged around the first heating component 122. The first heating component 122 and the second heating component 124 are spaced apart, thereby expanding the effective range of the heating component 120 and improving the adaptability of the heating component 120 to cookware.

[0072] At least two second temperature sensing elements 130 are disposed between the first heating assembly 122 and the second heating assembly 124 and / or on the outside of the second heating assembly 124.

[0073] Optionally, the first heating component 122 and the second heating component 124 are connected in series in terms of electrical connection. They can be formed by winding one or a group of wires, and during the winding process, they are separated into two parts, one part being the first heating component 122 and the other part being the second heating component 124.

[0074] like Figure 8 As shown, in some embodiments, optionally, the heating component 120 includes a first heating component 122 and a second heating component 124. The first heating component 122 is disposed around the first temperature sensing element 110, and the second heating component 124 is disposed around the first heating component 122. At least one second temperature sensing element 130 is disposed between the first heating component 122 and the second heating component 124, and at least one second temperature sensing element 130 is disposed outside the second heating component 124.

[0075] In this embodiment, the heating assembly 120 includes a first heating assembly 122 and a second heating assembly 124. The first heating assembly 122 is disposed around the first temperature detection element 110, and the second heating assembly 124 is disposed around the first heating assembly 122. The first heating assembly 122 and the second heating assembly 124 are spaced apart to provide installation space for the second temperature detection element 130. At least one second temperature detection element 130 is disposed between the first heating assembly 122 and the second heating assembly 124, and at least one second temperature detection element 130 is disposed outside the second heating assembly 124. This allows the second temperature detection element 130 to detect the temperature of the first heating assembly 122 and / or the second heating assembly 124 at multiple locations. Even if some of the second temperature detection elements 130 are affected by the cookware, another second temperature detection element 130 can still accurately detect the temperature of the first heating assembly 122 and / or the second heating assembly 124.

[0076] like Figure 8 As shown, in some embodiments, optionally, there are two second temperature detection elements 130, with the first temperature detection element 110 located between the two second temperature detection elements 130.

[0077] In this embodiment, there are two second temperature detection elements 130, and the first temperature detection element 110 is located between the two second temperature detection elements 130, thereby reducing the number of second temperature detection elements 130, reducing production costs, and increasing the distance between the two second temperature detection elements 130, reducing the possibility that the two second temperature detection elements 130 are simultaneously affected by the cookware.

[0078] like Figure 8 As shown, the first temperature detection element 110 is disposed at the center of the heating assembly 120, and two second temperature detection elements 130 are disposed between the first heating assembly 122 and the second heating assembly 124, and on the outside of the second heating assembly 124.

[0079] In this process, axis 1 and axis 2 are established on the heating device 100, and a first line is established between the two second temperature detection elements 130. Axis 1 and axis 2 are perpendicular to each other, and the two second temperature detection elements 130 are located on both sides of axis 2 and on the same side of axis 1.

[0080] The two second temperature detection elements 130 are distributed roughly on opposite sides of axis 2, and the straight-line distance between the two second temperature detection elements 130 is maximized. Based on the two second temperature detection elements 130, their temperature difference and the temperature rise rate of the second temperature detection elements 130, it is determined whether the heating component 120 has reached the preset temperature threshold.

[0081] like Figure 9As shown, in some embodiments, optionally, with the first temperature sensor 110 as the vertex, the included angle R formed by the first temperature sensor 110 and the two second temperature sensors 130 is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0082] In this embodiment, with the first temperature sensor 110 as the vertex, the included angle R formed by the first temperature sensor 110 and the two second temperature sensors 130 is greater than or equal to 90 degrees and less than or equal to 180 degrees, thereby ensuring that the distance between the two first temperature sensors 110 is relatively large, further reducing the possibility that the two second temperature sensors 130 will be affected by the cookware at the same time.

[0083] like Figure 11 As shown, the area covered by cookware 1 or cookware 2 does not have a second temperature detection element 130. That is, both second temperature detection elements 130 are located outside the area covered by cookware 1 or cookware 2. When one second temperature detection element 130 detects that the temperature of heating component 120 exceeds the preset temperature threshold T0, it reduces the power of heating component 120 so that the maximum temperature of heating component 120 remains below the preset temperature threshold T0.

[0084] like Figure 12 As shown, there is only one second temperature detection element 130 in the area covered by cookware 1 or cookware 2. There is also a second temperature detection element 130 located outside the area covered by cookware 1 or cookware 2. At this time, the temperature of the heating element 120 located outside the area covered by cookware 1 or cookware 2 can be detected by the second temperature detection element 130 located outside the area covered by cookware 1 or cookware 2. If the second temperature detection element 130 located outside the area covered by cookware 1 or cookware 2 detects that the temperature of the heating element 120 exceeds the preset temperature threshold T0, the power of the heating element 120 is reduced so that the maximum temperature of the heating element 120 is kept below the preset temperature threshold T0.

[0085] like Figure 13 As shown, if the pot is large enough and placed in the center of the heating element 120, completely covering the heating element 120 and the two second temperature sensors 130, the heating element 120 exchanges heat with the pot quickly, resulting in a uniform temperature. Both second temperature sensors 130 can detect the temperature of the heating element 120 and determine whether to reduce its power. For example, if the temperature of the heating element 120 reaches a preset temperature threshold, its power is reduced; if the temperature of the heating element 120 is below the preset temperature threshold, its power is not reduced. The preset temperature threshold can be the operating limit temperature of the heating element 120, or a temperature slightly lower than its operating limit temperature.

[0086] like Figure 14As shown, the pot offset just covers the two second temperature detectors 130. There is a heating element 120 area on the left side that is not covered by the bottom of the pot. At this time, the temperature difference between the two second temperature detectors 130 can be used to determine whether the preset temperature difference has been reached, and thus whether the temperature of the heating element 120 has reached the preset temperature threshold T0. One of the second temperature detectors 130 is located at the edge of the bottom of the pot, and its detected temperature will be higher than that of the second temperature detector 130 located in the middle of the bottom of the pot. Therefore, the maximum temperature of the heating element 120 can be determined by the temperature difference between the two second temperature detectors 130 based on experience or experiments, thereby reducing the risk of damage to the heating device 100.

[0087] like Figure 15 As shown, the pot offset just covers the two second temperature detectors 130, and the upper part of the heating element 120 is not covered by the pot. Since both second temperature detectors 130 are at the edge of the pot, the first temperature detector 110 is needed to assist in the judgment. At this time, the two second temperature detectors 130 detect similar temperatures, but the area covered by the pot is relatively small. The temperature rise rate of the pot can be detected by the first temperature detector 110. At this time, the area covered by the pot to the heating element 120 is relatively small, and the temperature rise rate is detected to be relatively slow. Therefore, it can be judged that the temperature of the heating element 120 is abnormal and the power is reduced so that the working temperature of the heating element 120 is always below the preset temperature threshold T0.

[0088] As shown above, when the cookware is arbitrarily offset, two second temperature detectors 130 and one first temperature detector 110 are set up, which can basically cover various cookware offset states and identify the highest temperature state of the heating component 120. This is used to determine the highest temperature of the heating component 120 and to determine whether to reduce the power of the heating component 120.

[0089] In some embodiments, the first temperature sensing element 110 may optionally be a thermistor.

[0090] In this embodiment, the first temperature detection element 110 is a thermistor. Thermistors have high sensitivity and can better detect the temperature of the cookware.

[0091] In some embodiments, the second temperature sensing element 130 may optionally be a thermocouple.

[0092] In this embodiment, the second temperature detection element 130 is a temperature measuring thermocouple. The temperature measuring thermocouple has high reliability, thereby improving the accuracy of temperature detection of the heating component 120.

[0093] like Figure 1 and Figure 8 As shown, in some embodiments, the heating component 120 may optionally be a heating coil, and the heating component 120 is wound in a circular shape.

[0094] In this embodiment, the heating component 120 is a heating coil, which is wound in a circular shape to obtain a circular heating component 120. The circular heating component 120 can better adapt to the cookware.

[0095] like Figure 1 , Figure 2 , Figure 8 and Figure 10 As shown, in some embodiments, optionally, it further includes: a heat insulation layer 140 disposed on one side of the heating assembly 120, the heat insulation layer 140 having at least three through holes 142, and the first temperature sensing element 110 and the second temperature sensing element 130 being disposed corresponding to the through holes 142.

[0096] In this embodiment, the heating device 100 further includes a heat insulation layer 140, which is disposed on one side of the heating assembly 120. Corresponding to the first temperature sensor 110 and the second temperature sensor 130, at least three through holes 142 are provided. One through hole 142 corresponds to the first temperature sensor 110, and at least two through holes 142 correspond to at least two second temperature sensors 130. The heat insulation layer 140 reduces the impact of the heating assembly 120 on other components of the heating device 100.

[0097] Two or more through holes 142 for the second temperature sensing element 130 can be provided on the edge of the insulation layer 140. Considering the comprehensiveness and economy of the temperature sensing range coverage, three second temperature sensing elements 130 can be selected to be evenly distributed in a circle on the edge of the insulation layer 140. Of course, the second temperature sensing elements 130 can also be unevenly distributed, but even distribution is better.

[0098] Alternatively, two or more through holes 142 for the second temperature sensing element 130 can be provided in the middle position of the insulation layer 140. Considering the comprehensiveness of the temperature sensing range coverage and economy, two second temperature sensing elements 130 can be set in the middle of the insulation layer 140.

[0099] like Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, the heat insulation layer 140 has a boss 144, a first temperature sensing element 110 is disposed on the boss 144, and a second temperature sensing element 130 is located outside the boss 144.

[0100] In this embodiment, the heat insulation layer 140 has a boss 144, and a first temperature detection element 110 is disposed on the boss 144 so as to better detect the temperature of the cookware. The second temperature detection element 130 is located outside the boss 144. The second temperature detection element 130 is farther away from the cookware, so as to better detect the temperature of the heating component 120.

[0101] like Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, a heat insulation layer 140 is provided on one side of the heating component 120, that is, a metal winding is provided on the heat insulation layer 140, and the metal winding is coiled to form the heating component 120; the heating component 120 includes at least one continuously wound metal winding, the heating component 120 is spiral in plan view, and the cross-section of the metal winding is flat; a first temperature detection element 110 is provided at the center of the heating component 120 for testing the temperature of the cookware; two or more second temperature detection elements 130 are evenly distributed on the outermost ring of the heating component 120, and the heat insulation layer 140 is provided with corresponding through holes 142 for placing the second temperature detection elements 130; or, at least one second temperature detection element 130 is provided between the first heating component 122 and the second heating component 124, and at least one second temperature detection element 130 is provided on the outer side of the second heating component 124, and they are placed on opposite sides of axis 2;

[0102] The area of ​​the cookware covering the heating element 120 experiences rapid heat exchange, and the temperature of the heating element 120 in this area is lower than that of the area of ​​the heating element 120 not covered by the cookware.

[0103] Furthermore, by evenly distributing at least two second temperature detectors 130 along the outer edge of the insulation layer 140, at least one second temperature detector 130 can measure the temperature of the heating element 120 outside the area covered by the cookware under various cookware sizes and when the cookware is placed in the center or in various offset states. This temperature can be used to determine whether the temperature has reached the preset temperature threshold T0 of the heating element 120 and whether power reduction is required.

[0104] Alternatively, by setting two second temperature detectors 130 on opposite sides of the axis 2 of the first heating component 122 and the second heating component 124, and setting a first temperature detector 110 at the center position to detect the temperature of the cookware, the temperature of the heating component 120 outside the coverage area of ​​the cookware can be measured by at least one second temperature detector 130 under various sizes of cookware and under various offset states of the cookware being placed in the center or offset states. The offset position of the cookware can be determined based on the temperature difference between at least two second temperature detectors 130, and the temperature difference of the cookware temperature rise can be determined based on the first temperature detector 110, thereby comprehensively judging whether the temperature rise of the heating component 120 has reached the preset temperature threshold T0.

[0105] The metal winding of the heating component 120 is made of a metal material that can withstand temperatures of 600°C or higher, and the heat insulation layer 140 can be used to place and fix the heating component 120.
