Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic heater technology, and in particular to a multi-point temperature measurement structure for an all-glass IH heating health pot. Background Technology
[0002] Induction heating (IH) technology has been widely used in small kitchen appliances such as electric kettles and rice cookers due to its advantages of high efficiency, precision, and safety. In recent years, all-glass kettles have become a new market favorite due to their aesthetic appeal, chemical stability, and ease of cleaning. Applying IH technology to all-glass kettles typically requires coating the bottom of the glass with a magnetically conductive film layer (such as stainless steel or ferrite) to generate an eddy current effect for heating.
[0003] However, this structure presents significant technical challenges and safety risks:
[0004] 1. Mismatch in thermal stress between materials: The significant difference in thermal expansion coefficients between the glass and the magnetic film layer makes the interfacial stress highly susceptible to causing the glass to crack or the film layer to peel off under rapid heating, cooling, or high-temperature conditions. In the absence of water or with insufficient water (dry burning), the heat generated by the magnetic film layer cannot be absorbed by the liquid, and the temperature will rise sharply to over 600℃, far exceeding the tolerance limit of high borosilicate glass (usually around 450℃), causing the kettle to shatter instantly.
[0005] 2. Risk of dry burning and cracking: In the absence of water or with insufficient water (dry burning), the heat generated by the magnetic film layer cannot be absorbed by the liquid, and the temperature will rise sharply to over 600℃, far exceeding the tolerance limit of high borosilicate glass (usually about 450℃), causing the kettle to crack instantly.
[0006] 3. Risk of operating on an inclined surface: When the kettle is placed on an unstable inclined surface for heating, the liquid will pool on one side, causing part of the heating area to be exposed to the air, resulting in "localized dry burning". Traditional single-point or dual-point temperature measurement cannot fully detect this uneven temperature field and cannot trigger the protection in time, posing a risk of explosion.
[0007] Existing technologies for all-glass IH heating health pots typically employ a single temperature sensor at the center of the pot's bottom for protection, or a capacitive water level sensor on the side of the pot to monitor water level and prevent dry burning, thus preventing explosions. However, this approach cannot effectively address the issue of localized overheating caused by inclined heating, resulting in insufficient protection. Furthermore, the presence of water droplets on the inner wall of the pot can lead to misjudgments or delayed monitoring, compromising safety.
[0008] Therefore, there is an urgent need for an innovative solution to overcome the above-mentioned defects and ensure the absolute safety of IH heating all-glass kettles. Utility Model Content
[0009] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-point temperature measurement structure for an all-glass IH heating health pot.
[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a multi-point temperature measurement structure for an all-glass IH heating health pot, including: an all-glass pot body, a base and a main control unit;
[0011] The bottom of the all-glass kettle body is provided with a magnetic conductive film layer; the magnetic conductive film layer is arranged in a ring around the bottom of the all-glass kettle to form a heating zone; a low-temperature zone is formed in the area of the bottom of the all-glass kettle where no magnetic conductive film layer is provided; the base is provided with a working area; an electromagnetic heating module is provided below the working area; the working area is provided with a first temperature detection unit and a second temperature detection unit;
[0012] The first temperature detection unit includes at least three first temperature sensors corresponding to the heating zone; the first temperature sensors are asymmetrically distributed to monitor the temperature at different locations on the heating zone; the second temperature detection unit includes at least one second temperature sensor corresponding to the low temperature zone; the second temperature sensor is used to detect the temperature of the all-glass kettle body.
[0013] The main control unit is electrically connected to the electromagnetic heating module, the first temperature detection unit, and the second temperature detection unit; the main control unit can control the electromagnetic heating module to stop supplying power or reduce its heating power according to the temperature detected by the first temperature detection unit and / or the second temperature detection unit.
[0014] Optionally, the low-temperature zone is a circular region.
[0015] Optionally, the diameter of the low-temperature zone is not less than 35 mm.
[0016] Optionally, the base is provided with a microcrystalline plate in the working area; the first temperature sensor is embedded in the microcrystalline plate; the second temperature sensor passes through the microcrystalline plate, extends upwards, and can abut against the low temperature zone of the all-glass pot body.
[0017] Optionally, the low-temperature zone is provided with an upward-facing recessed temperature measuring part; the top of the second temperature sensor extends into the recessed temperature measuring part.
[0018] Optionally, a ceramic sleeve is provided at the top of the second temperature sensor.
[0019] Optionally, the second temperature sensor is provided with a telescopic spring and an elastic rubber cover; the ceramic sleeve is embedded in the ceramic sleeve; the telescopic spring is positioned against the bottom of the ceramic sleeve to push the second temperature sensor upward.
[0020] Optionally, at least three of the first temperature sensors are uniformly arranged circumferentially on the microcrystalline plate.
[0021] Optionally, the first temperature sensor and the second temperature sensor are NTC thermistors.
[0022] In this embodiment, the main control unit is electrically connected to the electromagnetic heating module, the first temperature detection unit, and the second temperature detection unit; the main control unit is configured to control the electromagnetic heating module to stop supplying power or reduce its heating power when the temperature value detected by any one of the temperature sensors in the first temperature detection unit reaches a first set threshold T1, or the temperature value detected by the second temperature detection unit reaches a second set threshold T2.
[0023] The beneficial effects of this utility model are:
[0024] 1. This invention achieves comprehensive and multi-layered active temperature protection, fundamentally eliminating the risk of explosion. It innovatively adopts the core concept of "zoned monitoring and multi-point linkage," constructing a redundant and comprehensive temperature monitoring network by arranging multiple asymmetrically distributed first temperature sensors in the first heating zone and independently setting second temperature sensors in the second low-temperature zone. The main control unit uses "OR" logic for control; as long as the temperature at any monitoring point reaches its set threshold, a protection action (power off or power reduction) is immediately triggered. This design ensures rapid and accurate response to various dangerous conditions such as dry burning, localized dry burning (e.g., inclined heating), and overall overheating, providing comprehensive protection and greatly enhancing the inherent safety of the product.
[0025] 2. Effectively solves the problem of localized overheating under conditions such as inclined surface heating. Addressing the limitation of traditional single-point temperature measurement in detecting uneven heating surface temperatures, this invention asymmetrically arranges at least three temperature monitoring points in a large heating area. When the kettle is placed on an inclined surface, liquid displacement causes some heating areas to be exposed and rapidly heat up. The sensor closest to this high-temperature point will detect the anomaly first and trigger protection, effectively preventing glass thermal stress cracking caused by localized overheating.
[0026] 3. It eliminates the reliance on easily interfered water level sensors, greatly enhancing reliability. This invention is entirely based on direct temperature detection for protection, completely avoiding the risks of false alarms, missed alarms, or delayed judgments caused by water vapor, mist, or droplets on the inner and outer sides of the kettle wall, which are common with traditional capacitive water level sensors. The temperature measurement method is unaffected by ambient humidity, resulting in a more direct and reliable response, achieving true dry-boil protection.
[0027] 4. The ingenious use of the glass kettle's structure enables efficient and accurate temperature sampling. By reserving a non-magnetic layer area at the center of the kettle's bottom to create a low-temperature zone, and directly placing a second temperature sensor there, the actual temperature changes of the kettle's body can be detected directly and quickly. The temperature in this area more sensitively reflects the overall heat accumulation inside the kettle, complementing the multi-point monitoring in the heating zone, together forming a rapid-response and comprehensive temperature protection system.

[0038] Example
[0039] Reference Figure 1 and Figure 2 The present invention proposes a multi-point temperature measurement structure for an all-glass IH heating health pot, comprising: an all-glass pot body 10, a base 20, and a main control unit;
[0040] The bottom of the all-glass kettle body 10 is provided with a magnetic conductive film layer 11; the magnetic conductive film layer 11 is arranged in a ring around the bottom of the all-glass kettle to form a heating zone 12; a low temperature zone 13 is formed in the area of the bottom of the all-glass kettle where the magnetic conductive film layer 11 is not provided; the base 20 is provided with a working area; an electromagnetic heating module 21 is provided below the working area; the working area is provided with a first temperature detection unit and a second temperature detection unit.
[0041] The first temperature detection unit includes at least three first temperature sensors 22 corresponding to the heating zone 12; the first temperature sensors 22 are distributed asymmetrically to monitor the temperature at different locations on the heating zone 12; the second temperature detection unit includes at least one second temperature sensor 23 corresponding to the low temperature zone 13; the second temperature sensor 23 is used to detect the temperature of the all-glass pot body 10.
[0042] The main control unit is electrically connected to the electromagnetic heating module 21, the first temperature detection unit, and the second temperature detection unit. The main control unit is configured to control the electromagnetic heating module 21 to stop supplying power or reduce its heating power when the temperature value detected by any temperature sensor in the first temperature detection unit reaches the first set threshold T1, or the temperature value detected by the second temperature detection unit reaches the second set threshold T2.
[0043] The beneficial effects of this utility model are:
[0044] 1. This invention achieves comprehensive and multi-layered active temperature protection, fundamentally eliminating the risk of explosion. It innovatively adopts the core concept of "zoned monitoring and multi-point linkage," constructing a redundant and comprehensive temperature monitoring network by arranging multiple asymmetrically distributed first temperature sensors 22 in the first heating zone 12 and independently setting second temperature sensors 23 in the second low-temperature zone 13. The main control unit uses "OR" logic for control; as long as the temperature at any monitoring point reaches its set threshold, a protection action (power off or power reduction) is immediately triggered. This design ensures rapid and accurate response to various dangerous conditions such as dry burning, localized dry burning (e.g., inclined surface heating), and overall overheating, providing comprehensive protection and greatly enhancing the inherent safety of the product.
[0045] 2. Effectively solves the problem of localized overheating under conditions such as inclined surface heating. Addressing the limitation of traditional single-point temperature measurement in detecting uneven heating surface temperatures, this invention asymmetrically arranges at least three temperature monitoring points in the larger heating area 12. When the kettle is placed on an inclined surface, liquid displacement causes some areas of the heating area 12 to be exposed and rapidly heat up. The sensor closest to this high-temperature point will detect the anomaly first and trigger protection, effectively preventing glass thermal stress cracking caused by localized overheating.
[0046] 3. It eliminates the reliance on easily interfered water level sensors, greatly enhancing reliability. This invention is entirely based on direct temperature detection for protection, completely avoiding the risks of false alarms, missed alarms, or delayed judgments caused by water vapor, mist, or droplets on the inner and outer sides of the kettle wall, which are common with traditional capacitive water level sensors. The temperature measurement method is unaffected by ambient humidity, resulting in a more direct and reliable response, achieving true dry-boil protection.
[0047] 4. The ingenious use of the glass kettle's structure enables efficient and accurate temperature sampling. By reserving a non-magnetic layer area at the center of the glass kettle's bottom to form a low-temperature zone 13, and directly placing a second temperature sensor 23 there, the actual temperature changes of the glass kettle body can be detected directly and quickly. The temperature in this area can more sensitively reflect the overall heat accumulation inside the kettle, complementing the multi-point monitoring in the heating zone 12, together forming a rapid-response and comprehensive temperature protection system.
[0048] In this embodiment, the first set threshold T1 is a high-temperature protection threshold set for dry burning and localized overheating, and the second set threshold T2 is a low-temperature protection threshold set for overall water boiling, with T1 > T2. This achieves precise temperature protection based on different levels and conditions. By setting two different thresholds, T1 > T2, the system can distinguish between the normal operating condition of "overall water boiling" and the dangerous operating condition of "dry burning without water or localized overheating." T2 is used to cut off the power (to prevent overflow or enter the heat preservation mode) when the water is boiling normally, while T1 is specifically used to prevent the glass from shattering at abnormally high temperatures. This design avoids misinterpreting boiling as dry burning and frequently triggering the protection, ensuring safety without affecting the normal user experience, making the product more intelligent and practical.
[0049] Specifically, the first threshold value T1 is set between 380℃ and 450℃; the second threshold value T2 is set between 105℃ and 120℃. Setting T1 between 380℃ and 450℃ ensures it is well above the boiling point of water, accurately identifying dry burning, while remaining below the critical temperature for softening, deformation, or cracking of borosilicate glass, providing ample safety margin for protection. Setting T2 between 105℃ and 120℃ reliably detects water boiling (considering atmospheric pressure and overheating), promptly cutting off heating to prevent continued boiling and overflow. These specific value ranges ensure the accuracy and effectiveness of the protection action.
[0050] In this embodiment, the low-temperature zone 13 is a circular area. The circular design ensures symmetry around the center of the pot's bottom, providing the most uniform reflection of the overall temperature in the central area of the pot and avoiding distortions or blind spots in temperature monitoring caused by irregular shapes. The circular shape also facilitates processing and quality control during production and plating, ensuring product consistency and reliability.
[0051] Specifically, the diameter of the low-temperature zone 13 is not less than 35mm. Specifying a diameter of not less than 35mm ensures that the low-temperature zone 13 has a sufficiently large area to truly form an effective low-temperature zone 13 region. This avoids excessive influence from the radiant and conductive heat generated by the surrounding high-temperature heating zone 12 during the heating process, thus ensuring that the second temperature sensor 23 reads the temperature that truly represents the kettle body itself, rather than the temperature "heated" by the heating zone 12, improving the authenticity and accuracy of the monitoring data.
[0052] In this embodiment, a microcrystalline plate 24 is provided in the working area of the base 20; a first temperature sensor 22 is embedded in the microcrystalline plate 24; a second temperature sensor 23 is inserted through the microcrystalline plate 24, extending upwards and abutting against the low-temperature zone 13 of the all-glass pot body 10. The microcrystalline plate 24 serves as heat insulation, insulation, and support, providing a stable and reliable working platform for the sensors. Embedding the first temperature sensor 22 in the microcrystalline plate 24 allows for accurate sensing of the temperature transmitted from the heating zone 12 without affecting the placement of the pot body. Inserting the second temperature sensor 23 through and protruding from the microcrystalline plate 24 allows it to directly and closely contact the low-temperature zone 13 at the bottom of the pot, greatly reducing thermal resistance and improving the response speed and control sensitivity to temperature changes in the glass body.
[0053] Specifically, the low-temperature zone 13 is provided with an upward-facing recessed temperature measuring part 14; the tip of the second temperature sensor 23 extends into the recessed temperature measuring part 14. The recessed part forms a positioning structure, which facilitates automatic alignment of the second temperature sensor 23 when the pot is placed, preventing misalignment. Secondly, the recessed part surrounds the sensor head, reducing airflow and heat dissipation in this area, forming a tiny "thermal chamber," which makes the temperature measured by the sensor more accurately reflect the temperature of the glass pot, avoiding temperature measurement fluctuations or inaccuracies caused by ambient airflow, and further improving the stability and accuracy of temperature measurement.
[0054] In this embodiment, a ceramic sleeve 231 is provided at the top of the second temperature sensor 23. Ceramic material has excellent insulation, high temperature resistance, and thermal conductivity. Using the ceramic sleeve 231 to wrap the top of the sensor can, on the one hand, protect the temperature sensor from the direct effects of long-term tight friction and high-temperature aging, thus extending its service life; on the other hand, it can ensure good heat conduction efficiency, ensuring that the temperature signal is transmitted to the sensor quickly and without loss, thus taking into account both durability and response speed.
[0055] Furthermore, the second temperature sensor 23 is equipped with a telescopic spring 232 and an elastic rubber cap 233; a ceramic sleeve 231 is embedded in the ceramic sleeve 231; the telescopic spring 232 is positioned below the ceramic sleeve 231 to lift the second temperature sensor 23 upwards. The combination of the telescopic spring 232 and the elastic rubber cap 233 provides a continuous, adaptive, and flexible clamping force for the second temperature sensor 23. This ensures that regardless of minor unevenness at the bottom of the kettle, the sensor tip maintains a tight and stable physical contact with the recessed area at the bottom of the kettle under the action of the spring, minimizing contact thermal resistance and avoiding temperature measurement lag or inaccuracy caused by poor contact, thus guaranteeing the immediacy and reliability of the protection. The elastic rubber cap 233 serves to seal against dust and protect the internal structure.
[0056] In this embodiment, at least three first temperature sensors 22 are evenly arranged circumferentially on the microcrystalline plate 24. This provides equally divided, comprehensive thermal monitoring of the entire annular heating zone 12. This layout most effectively captures any potential localized overheating anomalies on the heating ring. Regardless of the location of the hot spot, at least one sensor will detect it closest and fastest, achieving the most balanced and comprehensive monitoring coverage of the heating zone 12. This is the optimal layout strategy for effective localized protection.
[0057] In this embodiment, the first temperature sensor 22 and the second temperature sensor 23 are NTC thermistors.
[0058] In this embodiment, the workflow is as follows:
[0059] Normal heating state: The main control unit drives the electromagnetic heating module 21 to work, so that the magnetic film layer 11 of the all-glass pot body 10 generates heat, heating the pot and the liquid inside.
[0060] Anti-tilt dry-boil protection: If the kettle is placed on an incline or tilted, the liquid will flow to one side, exposing the heating zone 12 on the other side. The temperature of the heating zone 12 in this area and the temperature detected by the first temperature sensor 22 will rise sharply first. When the main control unit detects that the temperature of one of the first temperature sensors 22 reaches T1 (e.g., 400°C), it immediately cuts off the power to the electromagnetic heating module 21.
[0061] Anti-dry-burning protection: If the kettle body experiences dry burning, the temperature detected by the heating zone 12 and the first temperature sensor 22 will rise sharply. When the main control unit detects that the temperature of one of the first temperature sensors 22 reaches T1 (e.g., 400℃), it will immediately cut off the power supply to the electromagnetic heating module 21.
[0062] Boiling protection: After the liquid in the kettle boils, the heat is conducted to the low temperature zone 13. When the main control unit detects that the temperature has reached T2 (e.g., 108°C) by the second temperature sensor 23, it indicates that the water has boiled or dried up. The main control unit will also immediately cut off the power or reduce the power of the electromagnetic heating module 21.
[0063] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
