Description

Technical Field

[0001] This invention relates to the field of intelligent electrical appliance technology, and in particular to a temperature-measuring cookware and stove linkage system and method. Background Technology

[0002] Existing cookware with temperature measurement functions typically embeds temperature sensors in the covering or interlayer to accurately measure the pot's temperature, and these sensors are led out via leads to ensure the effectiveness of the temperature measurement function. However, temperature sensors often have a certain size, and embedding them in the pot body increases the thickness of the interlayer or covering, which is detrimental to heat conduction. Secondly, the leads of temperature sensors are generally short, requiring lead wires to be connected. This necessitates that the lead wire connection withstand temperatures above 500°C, but the strength of riveting or welding at this connection point is relatively weak at high temperatures, making it difficult to meet the strength requirements. Furthermore, the lead wires used to meet both high temperature resistance and high connection strength are very expensive. Summary of the Invention

[0005] Furthermore, the iron-based alloy material includes an alloy of austenitic stainless steel and a doped material, wherein the doped material includes at least one of silicon, aluminum, chromium, and nickel.

[0006] Furthermore, the temperature coefficient of resistance of the temperature sensing element is 0.0060℃. -1 ~0.0075℃ -1 The resistance temperature coefficient is the ratio of the resistance change of the temperature measuring element to the preset resistance value and the temperature difference. The resistance change is the difference between the current resistance value of the temperature measuring element at the current temperature and the preset resistance value of the temperature measuring element at the preset temperature. The temperature difference is the difference between the current temperature and the preset temperature.

[0007] Furthermore, the temperature measuring range of the temperature measuring element is 0℃~800℃.

The cookware control terminal sends the temperature information to the stove control terminal, so that the stove control terminal controls the fire intensity of the stove according to the temperature information.

[0013] Implementing this invention has the following beneficial effects: This invention employs a temperature sensing element made of iron-based alloy material, embedded inside the pot body for direct temperature measurement. The resistivity of this element changes with temperature, resulting in accurate and sensitive temperature measurement. Furthermore, the iron-based alloy material exhibits excellent heat resistance, solving the problem of traditional temperature sensors being unable to withstand high temperatures within the pot body. Moreover, the temperature sensing element is processed into a filament or sheet shape, resulting in a small thickness and minimal space occupation, without altering the original dimensions of the covering layer and / or intermediate layer within the pot body, which is beneficial for mass production and uniformity. Additionally, the low price of iron-based alloy material also helps reduce the production cost of this temperature-measuring cookware. Attached Figure Description

[0019] To address at least one of the problems of insufficient heat resistance of temperature sensors embedded in existing temperature-measuring cookware, which can easily lead to increased pot thickness, this invention provides a temperature-measuring cookware and stove linkage system and method. The temperature-measuring cookware includes a pot body and at least one temperature-measuring element. This element is made of iron-based alloy material, processed into a filament or sheet shape, and embedded in the pot body's covering layer and / or intermediate layer. Its resistivity changes with the pot body's temperature, thus accurately detecting the temperature within the pot body without affecting the thickness of the existing pot body's covering layer. It also exhibits good heat resistance, improving durability and stability, and is cost-effective. The stove linkage system includes the temperature-measuring cookware and the stove, enabling control of the stove's heat intensity based on the pot body temperature measured by the temperature-measuring element. This results in high linkage reliability and significantly improves the intelligent user experience.

[0020] The following combination Figure 1 This invention provides a detailed description of a temperature-measuring cookware according to an embodiment of the present invention.

[0021] Specifically, such as Figure 1 As shown, the temperature-measuring cookware includes a pot body 1 and at least one temperature-measuring element 2. The pot body 1 includes a layered covering layer, an intermediate layer, and a bottom pot body 1. The temperature-measuring element 2 is made of an iron-based alloy material, which is inexpensive. The resistivity of the temperature-measuring element 2 can change with the temperature of the pot body 1, thereby improving the accuracy and reliability of temperature detection. At the same time, the temperature-measuring element 2 uses the iron-based alloy material itself as a temperature sensor, which has good overall heat resistance, uniform heat resistance, and good oxidation resistance, effectively improving the durability and stability of the temperature-measuring element 2. In addition, the temperature-measuring element 2 is formed into a filament or sheet shape by addition of iron-based alloy material, with a very small overall thickness. The temperature-measuring element 2 is embedded in the covering layer and / or the intermediate layer, which does not affect the thickness of the existing covering layer and / or the intermediate layer. The improvement cost is low, and there is no need to customize the covering layer and / or the intermediate layer, which is conducive to large-scale uniform production.

[0022] Specifically, in some exemplary embodiments, the iron-based alloy material used to process the temperature measuring element 2 includes stainless steel, specifically austenitic stainless steel, which is mainly composed of elements such as chromium and nickel, and also includes a small amount of carbon. This austenitic stainless steel has a stable austenitic microstructure exhibiting a face-centered cubic lattice, is inexpensive, and has a large change in resistivity with temperature, which is beneficial to improving temperature measurement sensitivity and accuracy. At the same time, as the main processing material of the temperature measuring element 2, this austenitic stainless steel has good high-temperature resistance, that is, it deforms less at high temperatures and is not easily oxidized, so as to avoid accidental contact with oxygen and oxidation during the sintering process of cookware. It will not release harmful substances during use, and both processing safety and usage safety can be effectively improved.

[0023] For example, in some alternative embodiments, the austenitic stainless steel includes at least one of 304 stainless steel and 316 stainless steel. The upper limit of the high temperature for the linear change of resistivity of the austenitic stainless steel is 400°C, while the high temperature threshold for dry burning protection of cookware is generally around 300°C. The temperature measuring element 2 can meet the temperature measurement accuracy of the cookware within the effective detection temperature range.

[0024] Specifically, in some exemplary embodiments, the iron-based alloy material includes an alloy of austenitic stainless steel and doped materials. The doped materials include at least one of silicon, aluminum, chromium and nickel, which can improve the upper limit of the linear change in resistivity of the temperature measuring element 2 at high temperatures to a certain extent, which is beneficial to improving the temperature measurement accuracy and temperature measurement stability of the temperature measuring element 2.

[0025] For example, in some embodiments, the material of the temperature measuring element 2 is an alloy of austenitic stainless steel, silicon, and aluminum. Silicon and aluminum can form stable oxides with chromium in austenitic stainless steel, such as Cr2SiO5 and Al2O3. These oxides can suppress the disordered vibration of the metal lattice at high temperatures, slow down the nonlinear increase of resistivity with temperature, and expand the range of linear increase of resistivity with temperature. At the same time, silicon material can improve the high-temperature oxidation resistance of the temperature measuring element 2, prevent the temperature measuring element 2 from oxidizing and forming an oxide layer that would damage the resistance stability, and help improve the reliability of temperature measurement.

[0026] The silicon content in the temperature sensing element material is 0.8%–1.5% by mass, and the aluminum content is 0.3%–0.6% by mass. Understandably, the silicon content can be any value between 0.8% and 1.5%, and the aluminum content can be any value between 0.3% and 0.6%. For example, the silicon content can be 0.8%, 0.9%, 1.0%, 1.2%, 1.25%, 1.5%, etc., and the aluminum content can be 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 0.6%, etc. Thus, by doping with silicon and aluminum, the upper limit of the linear resistivity change of the temperature sensing element 2 can be generally increased to 600℃–650℃, effectively improving the temperature measurement accuracy and stability of the temperature sensing element 2 within a wider temperature measurement range.

[0027] In some preferred embodiments, the mass percentage of silicon in the temperature sensing element material is 1.0% to 1.3%, and the mass percentage of aluminum in the temperature sensing element material is 0.4% to 0.5%. This enables the temperature sensing element 2 to maintain a linear change in resistivity for a short time even at high temperatures up to 700°C, further improving the temperature measurement range and the accuracy of temperature measurement within the range.

[0028] Specifically, the temperature measuring range of the temperature measuring element 2 is 0℃~800℃. It should be noted that the temperature measuring range here refers to the temperature range in which the resistivity of the temperature measuring element 2 can change linearly. Within this temperature range, the resistivity of the temperature measuring element 2 can change linearly, thereby effectively improving the accuracy of temperature measurement. However, if the temperature measuring range exceeds this linearly changing resistivity range, the resistance of the temperature measuring element 2 will change abruptly. In the actual measurement process, the upper limit of this temperature measuring range can also be used as the threshold for judging high temperature anomalies. If a sudden change in the resistance value of the temperature measuring element 2 is detected, it is determined that the temperature measuring pot is in a severely high temperature state, so as to control the stove to stop heating the temperature measuring pot.

[0029] Understandably, the temperature measuring range of the temperature measuring element 2 can be any point value from 0℃ to 800℃; for example, the temperature measuring range of the temperature measuring element 2 can be 0℃, 10℃, 100℃, 500℃, 550℃, 600℃, 700℃, 750℃, 800℃, etc.; within this temperature measuring range, the resistivity of the temperature measuring element 2 changes linearly with temperature, resulting in high temperature measurement accuracy and good temperature measurement stability; for example, in some specific embodiments, for example, conventional 304 stainless steel is used as the temperature measuring element 2, and the temperature range of the linear change of resistivity of the temperature measuring element 2 is less than 400℃. Accordingly, the temperature measuring range of the temperature measuring element 2 can be selected from 0℃ to 400℃, that is, it can accurately measure the temperature even at 400℃.

[0030] Specifically, the upper limit of the temperature resistance of the temperature measuring element 2 is 600℃~1000℃; it can be understood that the upper limit of the temperature resistance of the temperature measuring element 2 can be any value within 600℃~1000℃; for example, the upper limit of the temperature resistance of the temperature measuring element 2 can be 600℃, 650℃, 700℃, 750℃, 800℃, 900℃, 1000℃, etc.; wherein, the metal wire material is considered to be resistant to high temperature if the softening or melting temperature is above 350℃, and the temperature resistance of the temperature measuring element 2 is much higher than 350℃, above 500℃, with good high temperature resistance performance, and can effectively maintain the temperature measuring element 2 without abnormality for a short time when the pot body 1 is empty, with good temperature measurement reliability; for example, in some exemplary embodiments, the upper limit of the temperature resistance of the temperature measuring element 2 is 500℃~800℃; in other exemplary embodiments, the temperature resistance range of the temperature measuring element 2 is 350℃~800℃.

[0031] Specifically, the temperature coefficient of resistance of temperature measuring element 2 is 0.0060℃. -1 ~0.0075℃ -1 Understandably, the temperature coefficient of resistance of the temperature sensing element 2 can be 0.0060℃. -1 ~0.0075℃ -1 The value at any point in the range; for example, the temperature coefficient of resistance of the temperature measuring element 2 can be 0.0060℃. -1 0.0060℃-1 0.0060℃ -1 0.0060℃ -1 0.0060℃ -1 0.0075℃ -1 Within this temperature coefficient of resistance range, the temperature coefficient of resistance is relatively large, so that for every 1°C increase in the temperature of the pot body 1, the resistance value of the temperature measuring element 2 can change significantly, thereby improving the sensitivity and accuracy of temperature detection; in some preferred embodiments, the temperature coefficient of resistance of the temperature measuring element 2 is 0.0062°C. -1 ~0.0070℃ -1 .

[0032] Specifically, the resistance temperature coefficient is the resistance temperature coefficient at a preset temperature. This resistance temperature coefficient is related to the material of the temperature measuring element 2, that is, the resistance temperature coefficient is determined by the material of the temperature measuring element 2. The resistance temperature coefficient is the ratio of the resistance change value of the temperature measuring element 2 to the preset resistance value and the temperature difference. The resistance change value is the difference between the current resistance value of the temperature measuring element 2 at the current temperature and the preset resistance value of the temperature measuring element 2 at the preset temperature. The temperature difference is the difference between the current temperature and the preset temperature.

[0033] As the current temperature of the pot body 1 changes, the current resistance value of the temperature measuring element 2 can be expressed by the following formula:

[0034] in, The current resistance value of temperature measuring element 2 at the current temperature. The preset resistance value of temperature measuring element 2 at a preset temperature. The temperature coefficient of resistance of the temperature measuring element 2 at the preset temperature. This represents the current temperature of pot body 1. This is the preset temperature for pot body 1.

[0035] For example, in one specific embodiment, if the preset temperature is 20°C, then the current resistance value of the temperature measuring element 2 can be specifically described as follows:

[0036] in, The current resistance value of temperature measuring element 2 at the current temperature. The preset resistance value of temperature measuring element 2 at 20℃. The temperature coefficient of resistance of temperature measuring element 2 at 20℃. This is the current temperature of pot body 1.

[0037] Specifically, in some preferred embodiments, the temperature measuring element 2 is embedded in the covering layer, which is an insulating material. This avoids direct contact between the temperature measuring element 2 and the metal parts of the pot body 1, reducing the risk of short circuits caused by electromagnetic induction or high-temperature oxidation, and improving safety. Furthermore, the fact that the temperature measuring element 2 is located in the covering layer also allows the environment in which the temperature measuring element 2 is located to be closer to the internal temperature of the pot, reducing the interference of the external temperature below the bottom pot body 1 on temperature detection. This allows the change in the resistance value of the temperature measuring element 2 to more accurately reflect the actual temperature change inside the pot, improving the accuracy and reliability of temperature detection.

[0038] Specifically, the covering layer includes at least one of ceramic coating and Teflon coating. During the processing and manufacturing of the temperature measuring cookware, the insulating material of the covering layer is coated on the surface of the pot body 1 in a liquid gel form, and then sintered and cured, so that the temperature measuring element 2 can be embedded in the gel-like insulating material of the covering layer before sintering. The sintered covering layer has a high viscosity gel, which isolates the temperature measuring element 2 and the metal material of the pot body 1 from each other and prevents them from contacting each other, greatly improving the insulation reliability.

[0039] Specifically, the thickness of the temperature measuring element 2 in the stacking direction is less than the thickness of the cover layer, so as to avoid the temperature measuring element 2 being exposed on the surface of the cover layer and to avoid the traces of the temperature measuring element 2 being visible on the appearance surface of the cover layer, thereby improving the appearance quality of the cover layer.

[0040] Specifically, the thickness of the temperature measuring element 2 in the stacking direction is less than or equal to a preset thickness, which is 25μm to 50μm. Understandably, the preset thickness can be any value within the range of 25μm to 50μm. For example, the preset thickness can be 25μm, 30μm, 35μm, 40μm, 45μm, 50μm, etc. For instance, in a specific embodiment, the preset thickness is 30μm, so the thickness of the temperature measuring element 2 in the stacking direction of the pot body 1 is less than or equal to 30μm. In this way, the thickness of the temperature measuring element 2 in the stacking direction is thin, which effectively avoids the impact on the existing thickness of the pot body 1, eliminates the need for custom intermediate interlayers and / or covering layers, and facilitates mass production with uniformity. In some preferred embodiments, the thickness of the temperature measuring element 2 in the stacking direction is 10nm to 25μm.

[0041] Specifically, such as Figure 1As shown, the temperature measuring cookware also includes a handle 3, which is connected to the pot body 1. The temperature measuring element 2 includes an integrally connected lead-out end 23 and a temperature measuring part 24. The lead-out end 23 extends from the inside of the pot body 1 into the handle 3, and after passing through the handle 3, it can be connected to the control end of the pot body 1, so as to control the fire intensity of the stove according to the temperature measured by the temperature measuring element 2. The temperature measuring part 24 is arranged in a waveform in the pot body 1. The curved waveform of the temperature measuring part 24 can increase the wire length and increase the resistance value of the temperature measuring element 2, so that the resistance value reaches the level of hundreds of ohms. This is beneficial to simplify the sampling circuit and also to increase the amount of resistance change with temperature, thereby improving the detection sensitivity and detection accuracy. In addition, the bending of the temperature measuring part 24 into a waveform winding can also prevent thermal stress damage, avoid short circuits, and improve durability and temperature measurement stability.

[0042] For example, such as Figure 1 As shown, in some optional embodiments, the temperature measuring unit 24 is arranged radially in a waveform pattern within the covering layer; in other optional embodiments, the temperature measuring unit 24 is arranged in a plurality of sub-waveform arrays within the covering layer.

[0043] Specifically, in some exemplary embodiments, the pot body 1 includes an inner ring region and an outer ring region. In the corresponding area of ​​the stove, the inner ring region is located on the inner ring flame of the stove's gas, and the outer ring region is located on the outer ring flame of the stove's gas; in this embodiment, as... Figure 1 As shown, at least one temperature measuring element 2 includes a first temperature measuring element 21 and a second temperature measuring element 22. The second temperature measuring element 22 is located in the inner ring area and is used to detect the current temperature of the inner ring area, that is, to detect the temperature of the inner ring flame of the gas. The first temperature measuring element 21 is located in the outer ring area and is arranged around the second temperature measuring element 22. It is used to detect the current temperature of the outer ring area, that is, to detect the temperature of the outer ring flame of the gas. Thus, the first temperature measuring element 21 and the second temperature measuring element 22 work together to more accurately measure the temperature of different areas of the pot body 1, so as to more efficiently control the fire intensity of the stove, with good controllability, high accuracy and good stability.

[0044] For example, if the first temperature sensor 21 detects that the outer ring area is heating up too quickly and is close to the protection temperature, it is determined that the current state is high-heat cooking, and the gas valve is shut off in advance. As another example, if the first temperature sensor 21 detects that the outer ring area is heating up at a moderate rate, while the second temperature sensor 22 detects that the inner ring area is heating up too quickly, it is determined that the current gas flame is small, and a higher protection temperature threshold can be set.

[0045] In the manufacturing process of this temperature-measuring cookware, a wire-like metal made of iron-based alloy material is embedded as the temperature measuring element 2 in the insulating material of the covering layer. At this time, the insulating material is in a liquid gel state. After sintering and solidification, it forms a gel-like covering layer with high viscosity. The temperature measuring element 2 is then encased inside the covering layer. Through the insulation and isolation between the covering layer and the metal part of the pot body 1, the temperature measuring element 2 and the pot body 1 are efficiently integrated. The temperature measuring element 2 is directly processed into a wire shape and embedded in the covering layer. Its thickness is extremely small, which can effectively avoid affecting the thickness of the existing covering layer of the pot body 1. The improvement cost is low, and it has good high-temperature resistance, which can greatly improve the accuracy and reliability of temperature detection.

[0046] On the other hand, this embodiment of the invention also provides a stove linkage system, including a stove and a temperature-measuring pot as described above. The stove includes a stove control terminal, and the temperature-measuring pot includes a pot control terminal. The lead-out end 23 of the temperature measuring element 2 extends into the handle 3 and is connected to the pot control terminal, so that the pot control terminal can obtain the resistance value of the temperature measuring element 2, and thus determine the current temperature in the pot body 1. The stove control terminal and the pot control terminal are communicatively connected, and can send a signal containing the current temperature in the pot body 1 to the stove control terminal via priority or wireless means, so that the stove control terminal can adjust the firepower or turn it on and off, and adjust the cooking status in real time. It has high integration, good linkage sensitivity and reliability, and can greatly improve the intelligent experience.

[0047] On the other hand, an embodiment of the present invention provides a stove linkage method for controlling the stove linkage system described above, such as... Figure 2 As shown, the method includes: S101, the cookware control terminal acquires the resistance value of the temperature measuring element, and the resistance value is related to the temperature of the temperature measuring cookware.

[0048] S103, the cookware control terminal performs temperature conversion based on the resistance value to obtain temperature information, which is used to indicate the temperature of the temperature-measuring cookware.

[0049] The cookware control terminal can directly read the resistance value of the temperature measuring element, or it can obtain the current value of the temperature measuring element by the voltmeter-ammeter method and then calculate it, or it can obtain the resistance value of the temperature measuring element by the constant current source method. The measurement accuracy is high, and this invention does not impose excessive limitations on it.

[0050] Temperature information is used to indicate the temperature of the cookware being measured, specifically the internal temperature of the pot. This temperature is related to the resistance value of the temperature measuring element, and the resistance value reflects the current internal temperature of the pot. The two are linearly correlated, which can greatly improve the accuracy and stability of temperature detection, reduce the risk of misjudgment, and improve the accuracy and reliability of subsequent adjustments to the stove's firepower intensity based on this temperature.

[0051] S105, the cookware control terminal sends the temperature information to the stove control terminal, so that the stove control terminal controls the fire intensity of the stove according to the temperature information.

[0052] By using temperature information, the cooktop control unit can determine the current cooking status and, based on the current cooking status, determine the corresponding firepower intensity of the cooktop at the current temperature. This allows the cooktop to adjust the firepower intensity in a timely and effective manner, avoiding risks such as excessively high firepower and serious overheating, and preventing adverse effects on the kitchen environment and user health.

[0053] Corresponding to the stove linkage method provided in the above embodiments of the present invention, the stove control terminal and pot control terminal in the stove linkage system provided in the embodiments of the present invention can realize the stove linkage method in the above method embodiments, wherein the pot control terminal may include: The acquisition module is used to acquire the resistance value of the temperature measuring element, and the resistance value is related to the temperature of the temperature measuring element; A temperature conversion module is used to perform temperature conversion based on the resistance value to obtain temperature information, which is used to indicate the temperature of the temperature measuring pot. The transmitting module is used to send the temperature information to the stove control terminal, so that the stove control terminal can control the fire intensity of the stove according to the temperature information.

[0054] Accordingly, the stove control terminal may include: The receiving module is used to receive temperature information sent by the cookware control terminal; The firepower adjustment module is used to control the firepower intensity of the stove based on the temperature information.

[0055] It should be noted that the cookware control terminal and stove control terminal provided in the above embodiments are only illustrative examples of the division of the above functional modules. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. In addition, the cookware control terminal and stove control terminal provided in the above embodiments belong to the same concept as the method embodiments, and their specific implementation process can be found in the method embodiments, which will not be repeated here.

[0056] The cooktop linkage system is controlled by a cookware control terminal and a cooktop control terminal. Each of the cookware control terminal and the cooktop control terminal includes a processor and a memory. The processor (or CPU (Central Processing Unit)) is the core component, and its main function is to interpret the memory instructions and process the data fed back by various modules. The processor is roughly divided into an arithmetic logic unit and a register unit. The arithmetic logic unit mainly performs related logical calculations (such as shift operations, logical operations, fixed-point or floating-point arithmetic operations and address operations), while the register unit is used to temporarily store instructions, data and addresses.

[0057] A memory is a storage device used to store software programs and modules.
