Description

Technical Field

[0001] This application relates to the field of heating control technology, and in particular to a heating base and its heating control method, device, computer equipment, storage medium and computer program product. Background Technology

[0002] Resistance wire heating bases are widely used for heating containers made of various materials such as iron, ceramic, and glass, and are commonly found in appliances such as electric kettles, tea makers, and warming stoves. Traditional heating control methods typically use a fixed power supply to continuously power the resistance wire to maintain stable heating.

[0003] In typical applications such as heating bases for cast iron kettles, poor heat conduction can easily occur over time. As a result, some heat cannot be effectively transferred to the kettle body and instead accumulates in and around the resistance wire, causing localized overheating. Prolonged exposure to this localized overheating accelerates the aging process of the resistance wire and significantly reduces its lifespan. Traditional power heating control methods lack mechanisms to address these changes in heat conduction, making it difficult to effectively prevent localized overheating.

[0004] Therefore, there is an urgent need to provide a heating control method that can effectively prevent local overheating of the heating base in order to extend the service life of the resistance wire. Summary of the Invention

[0005] Therefore, it is necessary to provide a heating base that can effectively avoid local overheating, as well as its heating control method, device, computer equipment, storage medium, and computer program product, in response to the above-mentioned technical problems.

[0006] Firstly, this application provides a heating control method for a heating base. The method includes:

[0007] In response to the start of the heating operation, the heating base is controlled to heat at the initial heating power for the initial heating time;

[0008] Obtain the heating rate corresponding to the initial heating time;

[0009] If the heating rate is not less than the preset heating rate threshold, the heating base is controlled to heat at the preset second heating power.

[0010] If the temperature is heated to the preset first temperature using the second heating power, then the heating base is controlled to heat using the preset fourth heating power.

[0011] Among them, the preset heating rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; and the preset first temperature is determined based on the protection temperature T of the heating component in the heating base.

[0021] In one embodiment, the preset third temperature is equal to the protection temperature T minus n1; the preset fourth temperature is equal to the protection temperature T minus n3; the value of n1 ranges from 5 to 30°C; and the value of n3 ranges from 50 to 80°C.

[0022] Secondly, this application also provides a heating control device for a heating base. The device includes:

[0023] The initialization module is used to respond to the start heating operation and control the heating base to heat at the initial heating power for the initial heating time;

[0024] The heating rate acquisition module is used to acquire the heating rate corresponding to the initial heating time;

[0025] The control module is used to control the heating base to heat at a preset second heating power if the heating rate is not less than a preset heating rate threshold; and to control the heating base to heat at a preset fourth heating power if the heating rate is heated to a preset first temperature at the second heating power.

[0026] Among them, the preset heating rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; and the preset first temperature is determined based on the protection temperature T of the heating component in the heating base.

[0027] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0028] In response to the start of the heating operation, the heating base is controlled to heat at the initial heating power for the initial heating time;

[0029] Obtain the heating rate corresponding to the initial heating time;

[0030] If the heating rate is not less than the preset heating rate threshold, the heating base is controlled to heat at the preset second heating power.

[0031] If the temperature is heated to the preset first temperature using the second heating power, then the heating base is controlled to heat using the preset fourth heating power.

[0032] Among them, the preset heating rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; and the preset first temperature is determined based on the protection temperature T of the heating component in the heating base.

[0033] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0034] In response to the start of the heating operation, the heating base is controlled to heat at the initial heating power for the initial heating time;

[0035] Obtain the heating rate corresponding to the initial heating time;

[0036] If the heating rate is not less than the preset heating rate threshold, the heating base is controlled to heat at the preset second heating power.

[0037] If the temperature is heated to the preset first temperature using the second heating power, then the heating base is controlled to heat using the preset fourth heating power.

[0038] Among them, the preset heating rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; and the preset first temperature is determined based on the protection temperature T of the heating component in the heating base.

[0039] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, performs the following steps:

[0040] In response to the start of the heating operation, the heating base is controlled to heat at the initial heating power for the initial heating time;

[0041] Obtain the heating rate corresponding to the initial heating time;

[0042] If the heating rate is not less than the preset heating rate threshold, the heating base is controlled to heat at the preset second heating power.

[0043] If the temperature is heated to the preset first temperature using the second heating power, then the heating base is controlled to heat using the preset fourth heating power.

[0044] Among them, the preset heating rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; and the preset first temperature is determined based on the protection temperature T of the heating component in the heating base.

[0045] Sixthly, this application also provides a heating base, including a heating base body and a controller, wherein the controller uses the above-described method to control the heating of the heating base body.

[0046] The aforementioned heating base and its heating control method, device, computer equipment, storage medium, and computer program product, after starting heating, first heat at the initial heating power for an initial heating time and obtain the temperature rise rate during this period. The preset temperature rise rate threshold is determined based on the standard flatness of the heating base. When the actual flatness of the base deviates from the standard flatness due to manufacturing tolerances or deformation during use, the contact thermal resistance increases, heat conduction is hindered, and the temperature of the heating element rises rapidly, making it easy for the actual temperature rise rate to reach or exceed the threshold. When the detected temperature rise rate is not less than the preset temperature rise rate threshold, it indicates that the flatness of the base has deviated from the standard state, and the heat transfer conditions have deteriorated. The heating base is then controlled to operate at a preset second heating power lower than the initial heating power to actively reduce heat output and suppress local heat accumulation. When the second heating power heats to a preset first temperature determined based on the heating element protection temperature T, it further switches to an even lower preset fourth heating power. The entire solution sensitively detects the deterioration of the base's flatness by comparing the heating rate with a threshold determined based on standard flatness, and dynamically reduces the power at different heating stages to promptly block the heat accumulation path, fundamentally avoiding local overheating.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] The heating control method for the heating base provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, the heating base is for an electric kettle. The entire electric kettle heating base includes a heating base body 102 and a controller 104. The controller 104 is located on the heating base body 102. The controller 104 responds to the start of the heating operation, controls the heating base to heat at an initial heating power for an initial heating time; obtains the corresponding temperature rise rate within the initial heating time; if the temperature rise rate is not less than a preset temperature rise rate threshold, controls the heating base to heat at a preset second heating power; if the temperature is heated to a preset first temperature at the second heating power, controls the heating base to heat at a preset fourth heating power; wherein, the preset temperature rise rate threshold is determined based on the standard flatness of the heating base; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; the preset first temperature is determined based on the protection temperature T of the heating element in the heating base.

[0054] In one embodiment, such as Figure 2 As shown, a heating control method for a heating base is provided, which is applied to... Figure 1 Taking controller 104 as an example, the following steps are included:

[0055] S200: In response to the start of the heating operation, control the heating base to heat the initial heating time with the initial heating power.

[0056] Initiating the heating operation refers to the user triggering the heating base to start working via a switch, button, touch screen, or remote command. In response to this operation, the controller activates the heating element in the heating base to provide a preset initial heating power. The specific value of the initial heating power P can be determined based on the rated power P of the heating base. 额定 The power rating P is typically set based on factors such as the type of container being used and the desired heating rate. 额定 Or a higher power value close to the rated power is used to achieve rapid heating. The initial heating time refers to a preset duration from the start of heating, the purpose of which is to provide a fixed observation window for obtaining the subsequent heating rate, so as to evaluate the speed of heating behavior under a unified benchmark. The length of the initial heating time can be reasonably selected according to the response characteristics of the temperature sensing element and the system sampling period, for example, it can be set to about 1 to 4 minutes.

[0057] S400: Obtain the heating rate corresponding to the initial heating time.

[0058] During the initial heating period, the controller collects temperature signals in real time from the heating element or its vicinity in the heating base via a temperature detection unit, and calculates the heating rate during this period based on the collected temperature data. The temperature detection unit can be any device capable of sensing temperature changes, such as a thermistor, thermocouple, or temperature sensor. Its placement can be determined according to actual needs, such as at the center of the heating element, near the heating element, or below the base's supporting surface—locations that easily reflect the degree of heat accumulation. The heating rate can be calculated by dividing the difference between the temperature at the end of the initial heating time and the temperature at the beginning by the initial heating time, or by obtaining the slope after linear fitting of multiple sets of sampled data; there are no restrictions on this method.

[0059] S600: If the heating rate is not less than the preset heating rate threshold, the heating base is controlled to heat with the preset second heating power; the preset heating rate threshold is determined based on the standard flatness of the heating base.

[0060] The standard flatness of a heating base refers to the flatness index of the base's bearing surface under normal working conditions. Its specific value can be preset according to product design requirements or industry standards. When the actual flatness of the heating base deviates from the standard flatness due to manufacturing tolerances, wear and tear, or thermal deformation, the contact state between the base and the bottom surface of the container will change, the contact thermal resistance will increase accordingly, and the path of heat transfer from the heating element to the container will be blocked, leading to a faster temperature rise near the heating element. Based on the above technical principle, this application indirectly identifies the flatness status of the base by monitoring the heating rate during the initial heating time and comparing it with a preset heating rate threshold determined based on the standard flatness. The preset heating rate threshold can be obtained through experimental calibration or theoretical calculation, and its specific value can be determined comprehensively based on factors such as the power of the heating element, the material and structure of the base, and the position and accuracy of the temperature sensing element. Specifically, the standard flatness of the heating base can be 1mm or 2mm.

[0061] Specifically, a temperature sensor can be placed at the center of the heating wire to detect temperature changes during the heating process. In the initial heating stage, if the bottom of the container is relatively flat and in good contact with the base, heat can be smoothly transferred upwards to the entire kettle body, and the temperature rise at the sensor will be relatively slow. Conversely, if the bottom of the container is uneven, heat conduction is uneven, and the heat generated by the heating wire cannot be effectively transferred upwards and accumulates at the bottom, the sensor will detect a faster temperature rise. Therefore, the contact condition between the base and the bottom of the container can be judged based on the heating rate of the sensor during the initial heating time. For example, a preset heating rate threshold can be set to 80℃ / min. When the heating rate of the sensor is not less than 80℃ / min, it is judged as poor flatness, indicating poor heat transfer conditions and a risk of localized overheating; when the heating rate of the sensor is less than 80℃ / min, it is judged as excellent flatness, indicating good heat transfer conditions.

[0062] When the heating rate is not less than the preset heating rate threshold, it indicates that the flatness of the base has deviated from the standard state, and the heat transfer conditions have deteriorated. Continuing to operate at the initial heating power at this time will exacerbate local heat accumulation. Therefore, step S600 controls the heating base to heat at a preset second heating power, which is less than the initial heating power. By actively reducing the heating power, the amount of heat generated per unit time is reduced, thereby suppressing the excessively rapid rise in the local temperature of the heating element. It can be understood that the specific value of the preset second heating power can be set according to actual needs. As an optional method, the preset second heating power P2 can be set to between 0.5 and 1 times the initial heating power P, i.e., P2 = 0.5P~P.

[0063] S800: If the second heating power is used to heat to the preset first temperature, the heating base is controlled to heat with a preset fourth heating power; the preset second heating power is greater than the preset fourth heating power; both the preset second heating power and the preset fourth heating power are less than the initial heating power; the preset first temperature and the protection temperature T based on the heating component in the heating base are determined.

[0064] The protection temperature T refers to the highest temperature limit that the heating element can reach under safe operating conditions. Its specific value can be determined based on the heat resistance rating, insulation requirements, and reliability test data of the heating element material. The preset first temperature can be set to a temperature value lower than the protection temperature T, and the preset second temperature can be set to another temperature value lower than the preset first temperature. When heating to the preset first temperature with the second heating power, it indicates that the heating element temperature is approaching the upper limit of the protection temperature, and the heating power needs to be further reduced to avoid overheating. At this time, the heating base is controlled to heat with a preset fourth heating power, where the preset fourth heating power is less than the preset second heating power, and both are less than the initial heating power.

[0065] Furthermore, the heating base temperature can be maintained between a preset second temperature and a preset first temperature using a preset fourth heating power, wherein the preset first temperature is higher than the preset second temperature, and the preset second temperature is determined based on the protection temperature T of the heating component in the heating base.

[0066] In a specific application example, the preset first temperature T1 is T-n2℃, and the preset second temperature T2 is T-n4℃, where n2 and n4 are preset values, and n2 is less than n4. For example, n2 can be 10~30℃, and n4 can be 55~80℃. The preset fourth heating power P4 can be set to 0.3 to 0.7 times the initial heating power P, i.e., P4 = 0.3P~0.7P. When the temperature of the sensing element reaches T-n2℃, heating is performed at the heating power P4, and the temperature of the sensing element is maintained within the temperature range of [T-n4, T-n2]℃ until heating ends. Through the above method, while ensuring continuous heating, the temperature of the heating element can be kept within a safe range below the protection temperature T.

[0067] The aforementioned heating base and its heating control method, after starting heating, first heats at the initial heating power for an initial heating time and obtains the heating rate during this period. The preset heating rate threshold is determined based on the standard flatness of the heating base. When the actual flatness of the base deviates from the standard flatness due to manufacturing tolerances or deformation during use, the contact thermal resistance increases, heat conduction is hindered, and the temperature of the heating element rises rapidly, making it easy for the actual heating rate to reach or exceed the threshold. When the heating rate is detected to be not less than the preset heating rate threshold, it indicates that the flatness of the base has deviated from the standard state, and the heat transfer conditions have deteriorated. The heating base is then controlled to operate at a preset second heating power lower than the initial heating power, actively reducing heat output and suppressing local heat accumulation. When the second heating power heats to a preset first temperature determined based on the heating element protection temperature T, it further switches to an even lower preset fourth heating power. The entire scheme, by comparing the heating rate with the threshold determined based on the standard flatness, sensitively detects the deterioration of the base's flatness and dynamically reduces the power at different heating stages, promptly blocking the heat accumulation path and fundamentally avoiding local overheating.

[0068] In one embodiment, the preset second heating power is k2 * initial heating power, where k2 ranges from 0.5 to 1; the preset fourth heating power is k4 * initial heating power, where k4 ranges from 0.3 to 0.7. The preset first temperature is the protection temperature T - n2; the preset second temperature is the protection temperature T - n4; where n2 ranges from 10 to 30°C; and where n4 ranges from 55 to 80°C.

[0069] In this embodiment, the preset second heating power P2 = k2 * initial heating power P, where k2 can be 0.5~1, i.e., P2 = 0.5~1P; the preset fourth heating power P4 = k4 * initial heating power P, where k4 can be 0.3~0.7, i.e., P4 = 0.3~0.7P. Additionally, the preset first temperature T1 = protection temperature T - n2, where n2 ranges from 10 to 30℃; and the preset second temperature T2 = protection temperature T - n4, where n4 ranges from 55 to 80℃.

[0070] In one embodiment, such as Figure 3 As shown, the heating control of the aforementioned heating base also includes:

[0071] S700: If the heating rate is less than the preset heating rate threshold, the heating base will be controlled to heat at the initial heating power.

[0072] When the heating rate obtained in step S400 is less than the preset heating rate threshold, it indicates that the actual flatness of the heating base is close to or reaches the standard flatness, the contact between the base and the bottom surface of the container is good, the contact thermal resistance is small, and heat can be smoothly conducted from the heating element to the container, and heat accumulation is unlikely to occur near the heating element. Under this condition, there is no need to reduce the heating power, and the controller continues to control the heating base to maintain the initial heating power to maintain high heating efficiency, so that the medium in the container can be heated quickly. It can be understood that the method of determining the preset heating rate threshold is the same as that in the aforementioned step S600, both based on the standard flatness of the heating base. By comparing the actual heating rate with the threshold, the flatness status of the base is identified and controlled accordingly.

[0073] S900: If the initial heating power is used to heat to the preset third temperature, the heating base is controlled to heat at the preset third heating power and the temperature of the heating base is maintained between the preset fourth temperature and the preset third temperature; wherein the preset third heating power is less than the initial heating power; the preset third heating power is greater than the preset fourth heating power; and the preset third temperature is greater than the preset fourth temperature.

[0074] When heating continues at the initial power, and the temperature of the heating element gradually rises to the preset third temperature, it indicates that the base temperature is approaching the temperature range requiring adjustment. It should be noted that the preset third temperature is determined based on the protection temperature T of the heating element in the heating base, and its meaning is similar to the aforementioned preset first temperature; both are used to indicate that the heating element temperature has reached the control point where the heating power needs to be switched. Specifically, the preset third heating power is lower than the initial heating power to appropriately reduce the heating intensity when the temperature approaches the target range, avoiding temperature overshoot exceeding the safe range. Simultaneously, the preset third heating power is higher than the aforementioned preset fourth heating power because, under conditions of good flatness, heat conduction is smooth, and heat is less likely to accumulate at the heating element. Therefore, a relatively higher maintenance power can be used to ensure continuous heating without causing localized overheating. Maintaining the heating base temperature between the preset fourth and preset third temperatures means that the temperature fluctuates within a temperature range where the preset fourth temperature is the lower limit and the preset third temperature is the upper limit, by adjusting the heating power. The preset fourth temperature is lower than the preset third temperature; together, they define a safe temperature maintenance window.

[0075] In one embodiment, the preset third heating power P3 = k3 * initial heating power P, where the value of k3 ranges from 0.4 to 0.8, i.e., P3 = 0.4 to 0.8P. The preset third temperature T3 = protection temperature T - n1; the preset fourth temperature T4 = protection temperature T - n3; the value of n1 ranges from 5 to 30°C; and the value of n3 ranges from 50 to 80°C.

[0076] In practical applications, the preset third heating power P3 can be obtained based on experimental calibration. Taking an electric kettle heating base as an example, when the temperature sensor reaches the preset third temperature T3 = T - n1 (n1 depends on the kettle body material), the water temperature is generally close to 90℃. At this point, if high-power heating is used, violent boiling may occur, causing water vapor to splash and overflow from the spout, affecting personal safety and user experience. Therefore, P3 can specifically be the power required to heat the maximum amount of water to boiling point without overflowing.

[0077] To illustrate the heating control method of the heating base of this application in detail, the specific control process will be described in detail below using an application example.

[0078] In a specific application example, the initial heating power P = the rated heating power P 额定=2000W; preset heating rate threshold is 80℃ / min, which corresponds to the standard flatness of the heating base of 2mm; protection temperature is 110℃; preset first temperature T1 = protection temperature T - n2; n2 is 20℃, that is, preset first temperature T1 = 90℃; preset second temperature T2 = protection temperature T - n4, n4 is 60℃, that is, preset second temperature T2 = 50℃. Preset second heating power P2 = k2 * initial heating power P, k2 is 0.8, that is, preset second heating power P2 = 0.8 * 2000W = 1600W. Preset fourth heating power P4 = k4 * initial heating power P, k4 is 0.5, that is, preset fourth heating power P4 = 0.5 * 2000W = 1000W. The preset third heating power P3 = k3 * initial heating power P, where k3 is 0.6, meaning the preset third heating power P3 = 0.6 * 2000W = 1200W. The preset third temperature T3 = protection temperature T - n1, where n1 is 15℃, meaning the preset third temperature T3 = 95℃; the preset fourth temperature T4 = protection temperature T - n3, where n3 is 50℃, meaning the preset fourth temperature is 60℃.

[0079] After the user initiates the heating operation, the controller first executes step S200, controlling the heating base to start heating with an initial heating power of 2000W, and the initial heating time is set to 60 seconds. During these 60 seconds, the controller continuously collects temperature data through a temperature sensor located at the center of the heating wire, and executes step S400 to calculate the heating rate during this period.

[0080] Case 1: The heating rate is not less than the preset heating rate threshold (poor flatness).

[0081] If the calculated heating rate is 95℃ / min, which is not less than the preset heating rate threshold of 80℃ / min, it indicates that the flatness of the base deviates from the standard flatness by 2mm, increasing the contact thermal resistance, hindering heat conduction, and posing a risk of localized overheating. At this time, the controller executes step S600, reducing the heating power from the initial 2000W to the preset second heating power of 1600W, actively reducing heat output and suppressing the continuous accumulation of heat at the bottom. During the continued heating at 1600W, the temperature detected by the temperature sensor gradually increases. When the temperature sensor reaches the preset first temperature of 90℃, the controller executes step S800, further reducing the heating power to the preset fourth heating power of 1000W, and enters the temperature maintenance stage. In this stage, the controller adjusts the heating power to maintain the temperature sensor temperature between the preset second temperature of 50℃ and the preset first temperature of 90℃, i.e., within the temperature range of [50℃, 90℃]. This temperature range is entirely below the protection temperature of 110℃.

[0082] Scenario 2: The heating rate is less than the preset heating rate threshold (smoothness is excellent).

[0083] If the calculated heating rate is 75℃ / min, which is less than the preset heating rate threshold of 80℃ / min, it indicates that the flatness of the base is close to or reaches the standard flatness of 2mm, the contact thermal resistance is small, and the heat transfer conditions are good. At this time, the controller executes step S700 to maintain the initial heating power of 2000W to continue heating in order to maintain a high heating efficiency. During the continuous heating at 2000W power, the temperature of the temperature sensing bulb rises rapidly. When the temperature of the temperature sensing bulb reaches the preset third temperature of 95℃, the controller executes step S900 to reduce the heating power from the initial heating power of 2000W to the preset third heating power of 1200W, and enters the temperature maintenance stage. In this stage, the controller adjusts the heating power to maintain the temperature of the temperature sensing bulb between the preset fourth temperature of 60℃ and the preset third temperature of 95℃, that is, within the temperature range of [60℃, 95℃].

[0084] In this specific application example, the preset third heating power of 1200W is greater than the preset fourth heating power of 1000W. This is because when the flatness is good, the heat conduction is smooth and the heat is not easy to accumulate at the heating element. Therefore, a relatively high maintenance power can be used to ensure continuous and stable heating output without causing local overheating.

[0085] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0086] Based on the same inventive concept, this application also provides a heating control device for a heating base to implement the heating control method for the heating base described above. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations of one or more heating control device embodiments for a heating base provided below can be found in the limitations of the heating control method for the heating base described above, and will not be repeated here.
