Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to an electromagnetic cooking appliance. Background Technology

[0002] Current electromagnetic cooking appliances, such as induction cookers, primarily rely on sensors located beneath the cooktop to indirectly infer the pot's temperature by monitoring the cooktop's surface temperature. This method is limited by factors such as the cooktop material and heat loss, resulting in inaccurate and untimely temperature measurements. This affects temperature control during cooking, making it unsuitable for ingredients requiring high-temperature cooking and ultimately leading to unsatisfactory results. Furthermore, to prevent the cooktop supporting the pot from cracking due to inaccurate or untimely temperature measurements, high-temperature resistant microcrystalline glass is typically used, increasing production costs. Therefore, existing induction cookers face problems such as inaccurate temperature measurement and easily cracked cooktops, necessitating the search for effective solutions. Utility Model Content

[0003] The main purpose of this invention is to propose an electromagnetic cooking appliance that can accurately detect the temperature of the cookware and reduce costs.

[0004] To achieve the above objectives, the electromagnetic cooking appliance proposed in this utility model includes:

[0005] Bottom shell;

[0006] An electromagnetic heating device is installed inside the bottom shell;

[0007] A panel, located at the upper end of the bottom shell, is used to place cookware, and the panel has at least one through hole;

[0008] A temperature measuring unit is disposed on the lower side of the panel; and,

[0009] A heat-conducting bracket includes at least one heat-conducting element that passes through the through hole. The upper end of the heat-conducting element protrudes from the panel to have a heat-conducting surface for contacting a cookware placed on the panel. The lower end of the heat-conducting element is in contact with the temperature measuring part. The thermal conductivity of the heat-conducting bracket is set to be greater than that of the panel.

[0010] In one embodiment, a plurality of heat-conducting elements are provided, and the plurality of heat-conducting elements are arranged at intervals along the circumference of the panel.

[0011] In one embodiment, a plurality of the heat-conducting elements are disposed around the temperature measuring part.

[0012] In one embodiment, the temperature measuring unit is located at the middle position of the electromagnetic heating device; and / or,

[0013] The temperature measuring part elastically abuts against the panel.

[0014] In one embodiment, a portion of the panel is recessed upward to form a protrusion on the upper side of the panel, the protrusion being used to support a cookware placed on the panel;

[0015] The temperature measuring part abuts against the recessed area of ​​the panel.

[0016] In one embodiment, the heat-conducting element includes a metal heat-conducting strip.

[0017] In one embodiment, the metal heat-conducting strip includes an aluminum strip.

[0018] In one embodiment, the heat-conducting component includes a first heat-conducting section and a second heat-conducting section disposed on the upper and lower sides of the panel, and a connecting heat-conducting section connecting the first heat-conducting section and the second heat-conducting section. The first heat-conducting section is disposed covering the upper edge of the through hole, the second heat-conducting section extends from the lower edge of the through hole toward the temperature measuring part, and the connecting heat-conducting section passes through the through hole.

[0019] In one embodiment, the thermally conductive element is bonded to the panel.

[0020] In one embodiment, the panel comprises a borosilicate panel; and / or,

[0021] The temperature measuring unit includes a thermistor.

[0022] In the technical solution of this utility model, the electromagnetic heating device disposed within the bottom shell heats the cookware placed on the panel. The panel has at least one through hole, and the heat-conducting bracket includes at least one heat-conducting element. The heat-conducting element passes through the through hole. By protruding the upper end of the heat-conducting element from the panel, the cookware placed on the panel can not only contact the upper end of the heat-conducting element for heat conduction, but the heat-conducting element can also support the cookware, preventing direct contact between the cookware and the panel. When the cookware experiences localized abnormally high temperatures, the heat is not directly transferred to the panel, but rather transferred through the heat-conducting element to the temperature measuring part that is in contact with the lower end of the heat-conducting element. The panel does not require the use of a high-cost, high-temperature resistant microcrystalline glass panel. Furthermore, when the cookware experiences localized abnormally high temperatures, because the thermal conductivity of the heat-conducting bracket is set to be greater than that of the panel, the heat-conducting element can quickly transfer heat to the temperature measuring part. The electromagnetic heating device can adjust in a timely manner according to the detection information from the detection part to improve the accuracy of the detection. Attached Figure Description

[0036] Current electromagnetic cooking appliances, such as induction cookers, primarily rely on sensors located beneath the cooktop to indirectly infer the pot's temperature by monitoring the cooktop's surface temperature. This method is limited by factors such as the cooktop material and heat loss, resulting in inaccurate and untimely temperature measurements. This affects temperature control during cooking, making it unsuitable for ingredients requiring high-temperature cooking and ultimately leading to unsatisfactory results. Furthermore, to prevent the cooktop supporting the pot from cracking due to inaccurate or untimely temperature measurements, high-temperature resistant microcrystalline glass is typically used, increasing production costs. Therefore, existing induction cookers face problems such as inaccurate temperature measurement and easily cracked cooktops, necessitating the search for effective solutions.

[0037] This invention proposes an electromagnetic cooking appliance, aiming to provide an electromagnetic cooking appliance that can accurately detect the temperature of the cookware and reduce costs.

[0038] Please see Figures 1 to 4In one embodiment of this utility model, the electromagnetic cooking appliance 100 includes a bottom shell 1, an electromagnetic heating device 2, a panel 3, a temperature measuring part 4, and a heat-conducting bracket; the electromagnetic heating device 2 is disposed inside the bottom shell 1; the panel 3 is disposed at the upper end of the bottom shell 1 for placing a pot, and the panel 3 is provided with at least one through hole a; the temperature measuring part 4 is disposed on the lower side of the panel 3; the heat-conducting bracket includes at least one heat-conducting element 5, the heat-conducting element 5 passes through the through hole a, the upper end of the heat-conducting element 5 protrudes from the panel 3 to have a heat-conducting surface for contacting the pot placed on the panel 3, the lower end of the heat-conducting element 5 is in contact with the temperature measuring part 4, and the thermal conductivity of the heat-conducting bracket is set to be greater than the thermal conductivity of the panel 3.

[0039] It should be noted that when using electromagnetically heated cookware, to ensure the normal operation of the electromagnetic heating device 2, cookware containing iron or iron-containing materials is used. The changing magnetic field induces eddy currents in the cookware, generating resistance heat and causing the cookware to heat up rapidly. Therefore, multi-layered cookware is typically used, consisting of multiple layers of materials to improve thermal conductivity, durability, and heat convection performance. A typical multi-layered bottom structure includes a stainless steel outer layer, an aluminum middle layer, and a stainless steel bottom layer. During production or use, if there are gaps or incomplete contact between the bottom layer and the aluminum layer, it will lead to uneven heat conduction, resulting in localized overheating areas. Furthermore, unevenness or incomplete contact between the bottom of the cookware and the cooktop will also affect heat transfer. Even small gaps can cause uneven heat distribution at the bottom of the cookware.

[0040] It should also be noted that in related technologies, the temperature measuring part is in contact with the panel, and the temperature of the cookware is indirectly measured by measuring the temperature of the panel. However, some panel materials have good heat transfer performance in the vertical direction but poor heat transfer performance in the horizontal direction. If there is uneven heating at the bottom of the cookware, the panel may crack when the temperature exceeds the high temperature tolerance range of panel 3.

[0041] In the technical solution of this utility model, the electromagnetic heating device 2, disposed within the bottom shell 1, heats the cookware placed on the panel 3. The panel 3 has at least one through hole a. The heat-conducting support includes at least one heat-conducting element 5, which passes through the through hole a. By protruding the upper end of the heat-conducting element 5 from the panel 3, the cookware placed on the panel 3 can not only contact the upper end of the heat-conducting element 5 for heat conduction, but the heat-conducting element 5 can also support the cookware, preventing direct contact between the cookware and the panel 3. When the temperature of a part of the cookware is abnormally high, the heat will not be directly transferred to the panel 3, but will be transferred through the heat-conducting component 5 to the temperature measuring part 4 which is attached to the lower end of the heat-conducting component 5. The panel 3 does not need to use a high-cost high-temperature resistant microcrystalline glass panel 3. Furthermore, when the local temperature of the cookware is abnormally high, because the thermal conductivity of the heat-conducting bracket is set to be greater than that of the panel 3, the heat-conducting component 5 can quickly transfer the heat to the temperature measuring part 4. The electromagnetic heating device 2 can be adjusted in a timely manner according to the detection information of the detection unit to improve the accuracy of the detection.

[0042] It should be noted that the bottom shell 1 serves as the outer shell structure of the electromagnetic heating device 2, providing support for the internal components. The bottom shell 1 is generally assembled from a base and a top cover, with the electromagnetic heating device 2, fan, and electrical control device, among other components, located between the base and the top cover.

[0043] The panel 3 is located at the upper end of the bottom shell 1 and is used to place cookware. The panel 3 can be made of various materials. When the high temperature resistance requirement is high, the panel 3 can be made of a higher cost microcrystalline glass panel 3, while when the high temperature resistance requirement is low, the panel 3 can be made of a lower cost borosilicate glass panel 3. Of course, other lower cost materials can also be selected. In this solution, since the high temperature resistance requirement of the panel 3 is low, a lower cost material can be selected to make it, thereby reducing the overall cost of the electromagnetic cooking appliance 100.

[0044] It should also be noted that the heat-conducting component 5 has a heat-conducting surface that is in contact with the cookware. When there is one heat-conducting component 5, the size and shape of the heat-conducting surface can be set according to the type and shape of the cookware. When the cookware to be adapted is a round-bottomed pot, the heat-conducting surface can be set as a large arc surface that can fit the area to be detected on the bottom of the pot, or it can be set as an irregular curved surface.

[0045] When multiple heat-conducting elements 5 are provided, each heat-conducting surface can be respectively arranged in the area to be detected and supported. By providing heat-conducting elements 5, it is also possible to support irregularly shaped cookware and cookware with uneven bottoms.

[0046] It is understandable that thermal conductivity represents the amount of heat passing through a unit area per unit time under a unit temperature gradient. The higher the thermal conductivity, the more efficient the material is at conducting heat. "The thermal conductivity of the heat-conducting bracket is set to be greater than that of the panel 3," meaning that the heat transfer capacity of the heat-conducting component 5 is greater than that of the panel 3. Therefore, when a localized high temperature is generated in the cookware, the heat-conducting component 5 can quickly transfer heat to the temperature measuring unit 4, thereby improving the sensitivity and accuracy of the detection.

[0047] Specifically, in order to make the heat transfer between the cookware and the temperature measuring unit 4 more even, please refer to... Figure 1 In this embodiment, multiple heat-conducting elements 5 are provided, and the multiple heat-conducting elements 5 are arranged at intervals along the circumference of the panel 3.

[0048] Thus, the multiple heat-conducting elements 5 can form multiple heat conduction paths between the cookware and the temperature measuring unit 4, which can better detect temperature changes of the cookware at different locations and reduce temperature measurement errors caused by excessively high or low local temperatures.

[0049] It is also understandable that different cookware shapes and materials lead to uneven heating. By setting multiple heat-conducting elements 5, it is possible to better adapt to the shapes and thermal characteristics of various cookware, expand the temperature measurement range, and ensure that heat is effectively transferred to the temperature measuring unit 4 under different conditions, thereby improving the accuracy of temperature measurement. The multiple heat-conducting elements 5 can be set to a relatively uniform shape, which is easier to manufacture. Compared with irregularly shaped heat-conducting elements 5, this can reduce production difficulty and production costs.

[0050] By setting multiple heat-conducting elements 5 on the panel 3 and arranging them at intervals along the circumference, the uniformity, response speed and adaptability of heat conduction can be effectively improved, thereby further enhancing the temperature measurement accuracy of the electromagnetic cooking appliance 100.

[0051] Specifically, please refer to Figure 4 In this embodiment, a plurality of the heat-conducting elements 5 are disposed around the temperature measuring part 4.

[0052] It should be noted that, under normal circumstances, the high-temperature area of ​​the electromagnetic heating device 2 is mainly concentrated in the middle ring. When measuring temperature, the heat-conducting element 5 is used. The heat-conducting element 5 can cover multiple locations on the bottom of the pot, and can collect temperature data from multiple points on the bottom of the pot. This effectively expands the temperature measurement range, enabling the detection of the temperature distribution of the pot during the heating process, thereby improving the accuracy and reliability of temperature measurement.

[0053] In this way, multiple heat-conducting elements 5 are arranged around the temperature measuring unit 4, with one end of each element 5 directly attached to the temperature measuring unit 4. This allows heat from different locations on the bottom of the pot to be more concentratedly transferred to the temperature measuring unit 4. The temperature measuring unit 4 can detect heat information from various locations on the bottom of the pot, thereby achieving uniform monitoring of the temperature of the entire bottom of the pot. Furthermore, the number of heat conduction paths can be maximized within a limited space without occupying too much additional space.

[0054] In this embodiment, the temperature measuring unit 4 is located in the middle of the electromagnetic heating device 2.

[0055] The electromagnetic heating device 2 includes a mounting bracket and an electromagnetic coil disposed on the mounting bracket. It can be understood that the temperature measuring part 4 is mounted on the mounting bracket and is positioned corresponding to the center position of the mounting bracket.

[0056] Since the center of the mounting bracket typically corresponds to the hot spot area, which is the main area where food or containers are placed, positioning the temperature measuring unit 4 in the center of the electromagnetic heating device 2 facilitates concentrated measurement of the temperature in the central area, allowing for better acquisition of temperature data for that area and thus better detection of the cookware's temperature.

[0057] Please see Figure 4 and Figure 5 In this embodiment, the temperature measuring unit 4 elastically abuts against the panel 3.

[0058] "Elastic support" means that the temperature measuring part 4 can be installed on the mounting bracket by means of an elastic element. The elastic element can be a spring, a rubber part, or a silicone part, etc. Of course, other possible structural settings can also be adopted. The specific settings can be determined according to the actual situation. This specification does not limit this embodiment.

[0059] The temperature measuring unit 4 measures the temperature of the cookware not only by relying on the heat conduction bracket to conduct heat in the circumferential area of ​​the cookware, but also by directly obtaining the temperature of the central area of ​​the cookware through the temperature of the panel 3 itself.

[0060] The elastic deformation of the temperature measuring part 4 is set between 1mm and 3mm. By elastically abutting the temperature measuring part 4 against the panel 3, the temperature measuring part 4 can adapt to the slight changes of the panel 3 and always maintain a tight fit. This reduces thermal resistance during heat conduction and ensures that heat can be quickly and effectively transferred to the temperature measuring part 4. As a result, the temperature measuring part 4 can sense the temperature changes of the panel 3 in real time and avoid temperature measurement errors caused by poor contact.

[0061] It is understandable that during the use of the electromagnetic cooking appliance 100, the panel 3 may expand due to heating or deform due to changes in the external environment. The temperature measuring part 4 elastically abuts against the panel 3, and the contact pressure between the temperature measuring part 4 and the panel 3 can be flexibly adjusted to ensure that the optimal contact state is always maintained.

[0062] Further, please refer to Figure 5 and Figure 6 In another embodiment, a portion of the panel 3 is recessed upwards to form a protrusion 31 on the upper side of the panel 3, the protrusion 31 being used to support a cookware placed on the panel 3; the temperature measuring part 4 abuts against the recessed area of ​​the panel 3.

[0063] The panel 3 has a partial upward-facing recess, which can be achieved using a hot-press forming process. When the panel 3 is made of borosilicate glass, the borosilicate glass can be heated to its softening temperature, and then pressure is applied to force it into a mold. By applying pressure, it fills the shape of the mold, and after forming, it is gradually cooled to maintain the formed shape. By providing a groove on one side of the mold, when the heated glass is pressed into the groove, the glass will form a recess under pressure.

[0064] The temperature measuring part 4 can be correspondingly provided in the recessed area. The part of the temperature measuring part 4 that extends out of the mounting bracket is accommodated in the recessed area of ​​the panel 3, which can effectively reduce the thickness of the bottom shell 1.

[0065] The protrusion 31 formed on the upper side of the panel 3 can get closer to or directly contact the center of the bottom of the pot. When the protrusion 31 contacts the bottom of the pot, it can support the pot. In this way, the temperature measuring unit 4 can detect the temperature at the center of the pot more accurately, further improving the accuracy of the detection.

[0066] Specifically, in this embodiment, the heat-conducting element 5 includes a metal heat-conducting strip.

[0067] The heat-conducting component 5 is a long strip structure made of metal. Because metal has a high thermal conductivity, it can quickly and effectively conduct heat, rapidly transferring heat from the bottom of the pot to the temperature measuring part 4. Furthermore, the metal material itself has excellent thermal conductivity, avoiding excessive heat loss and improving the accuracy and speed of temperature measurement.

[0068] Meanwhile, since metal materials are easy to process through stamping, cutting and other processes, the metal heat-conducting strip can be processed into different lengths, widths and thicknesses according to actual needs to adapt to the shape of different cookware.

[0069] Specifically, in this embodiment, the metal heat-conducting strip includes an aluminum strip.

[0070] It should be noted that aluminum has a thermal conductivity of approximately 205 W / m·K, which is relatively high. Compared to some other metals, such as steel, aluminum has better thermal conductivity and can respond to temperature changes more quickly. Furthermore, aluminum is significantly less expensive than other high-performance thermally conductive materials such as copper. Therefore, using aluminum strips as the heat-conducting component 5 can reduce manufacturing costs while ensuring good performance.

[0071] Furthermore, aluminum has a low density, making the aluminum strip lighter than other metal materials of the same volume. This allows you to effectively reduce the weight of the electromagnetic cooking appliance 100, facilitating handling and installation.

[0072] Since the electromagnetic cooking appliance 100 uses electromagnetic heating, if the metal heat-conducting strip could be electromagnetically heated, the temperature detected by the temperature measuring unit 4 would not simply reflect the temperature of the cookware. To avoid detection errors, the metal heat-conducting strip cannot be made of a metal that can be electromagnetically heated. Aluminum strips have extremely high conductivity and exhibit weak eddy currents when placed in an alternating magnetic field, resulting in relatively little heat generation. Therefore, choosing aluminum strips as a material with high thermal conductivity and resistance to electromagnetic heating perfectly meets the requirements of this structure.

[0073] Specifically, please refer to Figure 2 In this embodiment, the heat-conducting component 5 includes a first heat-conducting section 51 and a second heat-conducting section 52 respectively disposed on the upper and lower sides of the panel 3, and a connecting heat-conducting section 53 connecting the first heat-conducting section 51 and the second heat-conducting section 52. The first heat-conducting section 51 is disposed covering the upper edge of the through hole a, the second heat-conducting section 52 extends from the lower edge of the through hole a toward the temperature measuring part 4, and the connecting heat-conducting section 53 passes through the through hole a.

[0074] Thus, by covering the upper edge of the through hole a with the first heat-conducting section 51, oil stains are prevented from entering the bottom shell 1 from the hole wall of the through hole a. Furthermore, the first heat-conducting section 51 covering the through hole a also makes the appearance of the panel 3 more aesthetically pleasing and its overall integrity stronger.

[0075] During installation, the heat-conducting component 5 can be tilted at a certain angle, and the second heat-conducting section 52 can be inserted into the through hole a. Then, the angle of the heat-conducting component 5 can be adjusted so that the connecting heat-conducting section 53 can also be inserted into the through hole a. Since the first heat-conducting section 51 extends beyond the connecting heat-conducting section 53, the first heat-conducting section 51 can completely cover the through hole a.

[0076] Understandably, to facilitate the installation of the heat-conducting component 5, the opening size of the through hole a can be set to be appropriately larger than the size of the second heat-conducting section 52 and the connecting heat-conducting section 53. However, this brings another problem: when the heat-conducting component 5 is installed in place, the heat-conducting component 5 and the through hole a are in a clearance fit, which poses a risk of loosening.

[0077] Furthermore, to prevent the heat-conducting bracket from loosening, the heat-conducting component 5 is bonded to the panel 3.

[0078] Thus, the heat-conducting component 5 is fixed to the panel 3 by adhesive or other types of bonding materials to ensure a stable connection between the heat-conducting component 5 and the panel 3, and to form a good seal between the panel 3 and the heat-conducting component 5, preventing moisture or other liquids from entering the bottom shell 1 and protecting electronic components from the effects of a humid environment.

[0079] Specifically, in this embodiment, the panel 3 includes a borosilicate glass panel 3.

[0080] It should be noted that borosilicate glass is a type of glass containing boron oxide (B2O3). High borosilicate glass has excellent high-temperature resistance and can withstand temperature changes. Its surface is smooth, easy to clean, and oil and food residue do not easily adhere to it.

[0081] In related technologies, panel 3 uses microcrystalline glass, but the production and raw material costs of microcrystalline glass are relatively high. High borosilicate glass has good performance, but when the cookware experiences abnormally uneven and continuous heating, high borosilicate glass has a slightly higher risk of breakage than microcrystalline glass panel 3, therefore its cost is relatively lower.

[0082] By setting multiple temperature measuring units 4, abnormal conditions of the cookware can be detected in a timely manner, thus avoiding the continuous generation of abnormally high temperatures on the panel 3. Therefore, the use of high borosilicate glass material can greatly reduce production costs.

[0083] In this embodiment, the temperature measuring unit 4 includes a thermistor.

[0084] It should be noted that the resistance of a thermistor changes significantly with temperature. Thermistors include NTC (negative temperature coefficient) thermistors and PTC (positive temperature coefficient) thermistors. By measuring the resistance of a thermistor, the current temperature can be indirectly calculated.

[0085] Because the thermistor is highly sensitive to temperature changes, it provides higher measurement accuracy within a specific temperature range compared to other temperature sensors, making it suitable for cooking scenarios involving frying, boiling, and stir-frying. The thermistor is small in size and easily integrated into the mounting bracket, without taking up excessive space. Therefore, choosing the thermistor as the temperature sensing element is suitable for the application scenarios and structural characteristics of the electromagnetic cooking appliance 100.

[0086] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
