Description

Technical Field

[0001] This invention relates to the field of data analysis and control technology, and in particular to a boiling water control method and apparatus based on water volume analysis. Background Technology

[0002] As people's living standards improve and their pace of life accelerates, their demand for efficient access to beverages (such as water, hot drinks, and milk tea) is constantly increasing. Especially for hot drinks, the efficiency of boiling water often determines the final efficiency of the water-based products. Take, for example, young parents preparing formula for their infants. Because different infants have different needs, the preparation time is not fixed, especially in the newborn stage, where this inconsistency is more pronounced. Furthermore, infants' needs for formula are often not only unpredictable but also urgent. Therefore, when preparing formula for an infant on short notice, heating the water to around 40-50 degrees Celsius to maximize boiling efficiency is crucial.

[0003] Therefore, it is particularly important to propose a technical solution to improve the efficiency of water boiling control. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0090] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0091] This invention discloses a water boiling control method and apparatus based on water volume analysis. During the continuous heating of target water at maximum heating power, it analyzes the target heating time required to heat the target water to the target temperature under the current water volume. Based on the maximum heating power and the target heating time, it continues to heat the target water, effectively improving boiling efficiency. Furthermore, since the variables used to calculate the target heating time are based on actual temperature changes and corresponding durations, it eliminates the influence of errors such as heating efficiency and power fluctuations under different environments. This further improves the accuracy of determining the target heating time required to heat the target water to the target temperature under different target water volumes, thereby improving the accuracy of controlling the heating of the target water to the target temperature during the boiling process. Detailed descriptions follow.

[0092] Example 1

[0093] Please see Figure 1 , Figure 1 This is a schematic flowchart of a water boiling control method based on water volume analysis disclosed in an embodiment of the present invention. Figure 1 The described water-based boiling control method can be applied to electrical appliances capable of heating / cooking / preparing water and other edible liquid products containing water. These electrical appliances may include, but are not limited to, kettles, formula makers, teapots, etc., and the embodiments of this invention are not limited thereto. Figure 1 As shown, the water boiling control method based on water volume analysis may include the following operations:

[0094] 101. Determine the first temperature difference obtained by heating the target water under the maximum heating power and preset heating time.

[0095] 102. Determine the second temperature difference between the current temperature of the target water and the target temperature.

[0096] 103. Based on the preset heating time, the first temperature difference, and the second temperature difference, determine the target heating time required to heat the target water to the target temperature.

[0097] 104. Heat the target water according to the maximum heating power and the target heating time.

[0098] The formula for determining the target heating time mentioned above can be:

[0099]

[0100] And, t 目 Used to represent the target heating time, t 预 ΔT2 is used to represent the preset heating time, ΔT1 is used to represent the second temperature difference, and ΔT1 is used to represent the first temperature difference.

[0101] According to the formula for determining the target heating time described above, by executing steps 101-103 as described in the embodiments of the present invention, the target heating time required to heat the target water to the target temperature under the current water volume can be analyzed, and the target water can be continuously heated under the maximum heating power and the target heating time.

[0102] For example, if the target water is heated using 800W for 60 seconds, the target water temperature will rise by 10 degrees Celsius, resulting in a first temperature difference of 10 degrees Celsius. Furthermore, if the current target water temperature is 30 degrees Celsius and the target temperature is 55 degrees Celsius, then the second temperature difference is 25 degrees Celsius. Based on the preset heating time of 60 seconds, the first temperature difference of 10 degrees Celsius, and the second temperature difference of 25 degrees Celsius, the target heating time can be calculated to be 150 seconds.

[0103] As can be seen, implementing the embodiments of the present invention can analyze the target heating time required to heat the target water to the target temperature under the current water volume during the continuous heating of the target water using the maximum heating power, and continue to heat the target water according to the maximum heating power and the target heating time, which can effectively improve the water boiling efficiency. Furthermore, since the variables for calculating the target heating time are all based on actual temperature changes and corresponding durations, the influence of errors such as heating efficiency and power fluctuations under different environments is eliminated, which can further improve the accuracy of determining the target heating time required to heat the target water to the target temperature under different target water volumes, thereby improving the accuracy of controlling the heating of the target water to the target temperature during the water boiling process.

[0104] Optionally, after heating the target water according to the maximum heating power and target heating time, the following operations may also be included:

[0105] It determines whether the current temperature of the target water is greater than the preset cooling threshold. If it is determined that the current temperature of the target water is greater than the preset cooling threshold, it controls the preset cooling unit to cool the target water to the target temperature.

[0106] As can be seen, implementing this optional embodiment can further adjust the current temperature of the target water to the target temperature based on the actual heating of the target water. The adjustment method may include cooling. While improving the water boiling efficiency and further controlling the accuracy of the water boiling temperature, it can flexibly control the water boiling temperature to be adjusted multiple times according to the user's actual needs.

[0107] In an optional embodiment, after determining the first temperature difference obtained by heating the target water at the maximum heating power and preset heating time, the method may further include the following operations:

[0108] Based on the preset water volume analysis algorithm and the first temperature difference, the target water volume for the target water use is determined.

[0109] And, based on the preset heating time, the first temperature difference, and the second temperature difference, determine the target heating time for heating the target water to the target temperature, including:

[0110] Based on the preset target heating algorithm, target water volume, and second temperature difference, the target heating time required to heat the target water to the target temperature is determined.

[0111] The preset target heating algorithm is derived from the preset water volume analysis algorithm.

[0112] Furthermore, the formula for determining the target water volume mentioned above can be:

[0113]

[0114] Where m represents the target water volume, Q represents the heat, c represents the isobaric specific heat of water and is a constant of 4.2, and ΔT1 represents the first temperature difference.

[0115] Furthermore, the formula for determining the aforementioned heat can be:

[0116] Q = P max t 预 η 当前 ;

[0117] Among them, P max Used to represent maximum heating power, t 预 η is used to represent the preset heating time. 当前 Used to indicate the current heating efficiency.

[0118] As can be seen, implementing this optional embodiment can determine the target heating time for heating the target water to the target temperature based on the different target water volumes, which can improve the efficiency of boiling water and further improve the accuracy of heating the target water to the target temperature under different target water volumes.

[0119] In this optional embodiment, as an optional implementation method, before determining the target water volume based on the preset water volume analysis algorithm and the first temperature difference, the method may further include the following operations:

[0120] The current heating efficiency corresponding to the current altitude environment is determined based on the rate of temperature change per unit time of the first temperature difference.

[0121] Determine if the current heating efficiency is less than the preset heating efficiency. If the current heating efficiency is less than the preset temperature change rate, increase the boiling water pressure until the current heating efficiency is greater than or equal to the preset heating efficiency.

[0122] Additionally, if the current heating efficiency is greater than the preset heating efficiency, the preset heating efficiency is updated to the current heating efficiency.

[0123] The formula for determining the target heating time mentioned above can be:

[0124]

[0125] Furthermore, t 目 The target heating time is represented by c, which represents the isobaric specific heat of water and is a constant of 4.2. The target water volume is represented by m, ΔT2 represents the second temperature difference, and P represents the target heating time. max η is used to represent the maximum heating power. 预 Used to indicate the preset heating efficiency.

[0126] It is evident that implementing this optional embodiment can adjust the boiling pressure of the target water according to the influence of different atmospheric pressure environments corresponding to different altitudes on the target water, thereby adjusting the heating efficiency of the target water. Furthermore, while improving the heating efficiency of the target water, it can prevent the phenomenon of mismatch between the subsequently determined target heating time and the final desired target temperature, i.e., the failure to effectively improve the technical effect of heating the target water to the target temperature under different target water volumes. It can improve the richness of application scenarios and the robustness of water boiling control based on water volume analysis.

[0127] Example 2

[0128] Please see Figure 2 , Figure 2 This is a schematic flowchart of another water boiling control method based on water volume analysis disclosed in an embodiment of the present invention. Figure 2 The described water-based boiling control method can be applied to electrical appliances capable of heating / cooking / preparing water and other edible liquid products containing water. These electrical appliances may include, but are not limited to, kettles, formula makers, teapots, etc., and the embodiments of this invention are not limited thereto. Figure 2 As shown, the water boiling control method based on water volume analysis may include the following operations:

[0129] 201. Determine the first temperature difference obtained by heating the target water under the maximum heating power and preset heating time.

[0130] 202. Determine whether the current heating power corresponding to the target water is less than the maximum heating power. If it is determined that the current heating power is less than the maximum heating power, then proceed to step 203.

[0131] 203. Determine the compensation coefficient corresponding to the preset heating efficiency based on the difference between the maximum heating power and the current heating power.

[0132] 204. Update the preset heating efficiency based on the compensation coefficient;

[0133] 205. Increase the boiling water pressure based on the updated preset heating efficiency.

[0134] 206. Determine the target water volume based on the preset water volume analysis algorithm and the first temperature difference.

[0135] 207. Determine the second temperature difference between the current temperature of the target water and the target temperature.

[0136] 208. Based on the preset target heating algorithm, target water volume, and second temperature difference, determine the target heating time required to heat the target water to the target temperature.

[0137] 209. Heat the target water according to the maximum heating power and the target heating time.

[0138] The aforementioned preset target heating algorithm is derived from the aforementioned preset water volume analysis algorithm.

[0139] Furthermore, the formula for determining the target heating time mentioned above can be:

[0140]

[0141] Furthermore, t 目 The target heating time is represented by c, which represents the isobaric specific heat of water and is a constant of 4.2. The target water volume is represented by m, ΔT2 represents the second temperature difference, and P represents the target heating time. max η is used to represent the maximum heating power. 预 Used to indicate the preset heating efficiency.

[0142] As can be seen, implementing this optional embodiment enables water boiling control based on water volume analysis. It can adjust the heating efficiency in real time by adjusting the boiling gas pressure based on the fluctuation of the current power, thereby compensating for the fluctuation of power. While effectively improving the water boiling efficiency, it reduces the impact of errors such as heating efficiency and power fluctuation under different environments. It can further improve the accuracy of determining the target heating time required to heat the target water to the target temperature under different target water volumes, thereby improving the accuracy of controlling the heating of the target water to the target temperature during the water boiling process. It can further improve the application scenarios and control robustness of water boiling control based on water volume analysis.

[0143] In an optional embodiment, the method may further include the following operations:

[0144] During the process of heating the target water, the first temperature of the target water is collected, and it is determined whether the first temperature is greater than the preset temperature threshold. When it is determined that the first temperature is greater than the preset temperature threshold, the target water is heated to the target temperature according to the preset heating power.

[0145] In addition, after heating the target water to the target temperature, the second temperature of the target water is collected, and it is determined whether the second temperature is lower than the target temperature. When it is determined that the second temperature is lower than the target temperature, the operation of determining the first temperature difference obtained by heating the target water under the maximum heating power and preset heating time is executed.

[0146] The first and second temperatures mentioned above can be collected in real time or periodically or non-periodically at a predetermined time point; the preset heating power mentioned above can be a preset non-maximum heating power.

[0147] As can be seen, implementing this optional embodiment can detect the temperature of the target water during the heating process. When the temperature reaches a certain preset threshold, it can be continuously heated with low power to achieve the purpose of heating compensation, rather than using coarse full-power heating, which further improves the accuracy of heating the target water to the target temperature under different target water volumes.

[0148] Meanwhile, the optional implementation can also detect the temperature of the target water after heating it to the target temperature. If the temperature of the target water is lower than the target temperature, step 201 of the present invention and its corresponding subsequent steps are re-executed. This can further improve the water boiling efficiency and the accuracy of heating the target water to the target temperature under different target water volumes, so as to ensure that the target water continuously maintains the target temperature required by the user, and improve the humanization, application scenario richness, control robustness and intelligence of the solution.

[0149] In this optional embodiment, as an optional implementation method, the above-mentioned method for determining the preset heating power may include the following operations:

[0150] Determine the difference between the first temperature and the target temperature mentioned above;

[0151] Determine the target difference interval that matches the above difference in the preset difference interval set;

[0152] Based on the target difference range mentioned above, the corresponding preset heating power is determined.

[0153] Each of the aforementioned preset difference intervals corresponds to a preset heating power, and the aforementioned difference intervals include multiple differences.

[0154] As can be seen, implementing this optional embodiment can provide different low-power heating compensation for the target water according to the different temperatures of the target water collected, so as to ensure the accuracy of heating the target water to the target temperature under different target water volumes, while further improving the boiling efficiency, and achieving mutual promotion of heating efficiency and heating accuracy.

[0164] According to the above formula for determining the target heating time, the determination module 301 and the heating module 302 described in this embodiment of the invention can analyze the target heating time required to heat the target water to the target temperature under the current water volume, and continuously heat the target water under the maximum heating power and the target heating time.

[0165] For example, if the target water is heated using 800W for 60 seconds, the target water temperature will rise by 10 degrees Celsius, resulting in a first temperature difference of 10 degrees Celsius. Furthermore, if the current target water temperature is 30 degrees Celsius and the target temperature is 55 degrees Celsius, then the second temperature difference is 25 degrees Celsius. Based on the preset heating time of 60 seconds, the first temperature difference of 10 degrees Celsius, and the second temperature difference of 25 degrees Celsius, the target heating time can be calculated to be 150 seconds.

[0166] As can be seen, implementing the embodiments of the present invention can analyze the target heating time required to heat the target water to the target temperature under the current water volume during the continuous heating of the target water using the maximum heating power, and continue to heat the target water according to the maximum heating power and the target heating time, which can effectively improve the water boiling efficiency. Furthermore, since the variables for calculating the target heating time are all based on actual temperature changes and corresponding durations, the influence of errors such as heating efficiency and power fluctuations under different environments is eliminated, which can further improve the accuracy of determining the target heating time required to heat the target water to the target temperature under different target water volumes, thereby improving the accuracy of controlling the heating of the target water to the target temperature during the water boiling process.

[0167] In an optional embodiment, the determining module 301 described above is further configured to determine the target water volume of the target water based on a preset water volume analysis algorithm and the first temperature difference after determining the first temperature difference obtained by heating the target water under the maximum heating power and preset heating time.

[0168] Furthermore, the method by which the determining module 301 determines the target heating time for heating the target water to the target temperature based on the preset heating time, the first temperature difference, and the second temperature difference includes:

[0169] Based on the preset target heating algorithm, target water volume, and second temperature difference, the target heating time required to heat the target water to the target temperature is determined.

[0170] The preset target heating algorithm is derived from the preset water volume analysis algorithm.

[0171] Furthermore, the formula for determining the target water volume mentioned above can be:

[0172]

[0173] Where m represents the target water volume, Q represents the heat, c represents the isobaric specific heat of water and is a constant of 4.2, and ΔT1 represents the first temperature difference.

[0174] Furthermore, the formula for determining the aforementioned heat can be:

[0175] Q = P max t 预 η 当前 ;

[0176] Among them, P max Used to represent maximum heating power, t 预 η is used to represent the preset heating time. 当前 Used to indicate the current heating efficiency.

[0177] As can be seen, implementing this optional embodiment can determine the target heating time for heating the target water to the target temperature based on the different target water volumes, which can improve the efficiency of boiling water and further improve the accuracy of heating the target water to the target temperature under different target water volumes.

[0178] In this optional embodiment, as an optional implementation method, the determination module 301 is further configured to determine the current heating efficiency corresponding to the current altitude environment based on the unit time temperature change rate of the first temperature difference before determining the target water volume of the target water use according to the preset water volume analysis algorithm and the first temperature difference.

[0179] like Figure 4 As shown, the water boiling control device based on water volume analysis may further include:

[0180] The first judgment module 303 is used to determine whether the current heating efficiency is less than the preset heating efficiency.

[0181] The pressurization module 304 is used to increase the boiling water pressure when the first judgment module 303 determines that the current heating efficiency is less than the preset temperature change rate, until the current heating efficiency is greater than or equal to the preset heating efficiency.

[0182] The update module 305 is used to update the preset heating efficiency to the current heating efficiency when the current heating efficiency is greater than the preset heating efficiency.

[0183] The formula for determining the target heating time mentioned above can be:

[0184]

[0185] Furthermore, t 目 The target heating time is represented by c, which represents the isobaric specific heat of water and is a constant of 4.2. The target water volume is represented by m, ΔT2 represents the second temperature difference, and P represents the target heating time. max η is used to represent the maximum heating power. 预 Used to indicate the preset heating efficiency.

[0186] It is evident that implementing this optional embodiment can adjust the boiling pressure of the target water according to the influence of different atmospheric pressure environments corresponding to different altitudes on the target water, thereby adjusting the heating efficiency of the target water. Furthermore, while improving the heating efficiency of the target water, it can prevent the phenomenon of mismatch between the subsequently determined target heating time and the final desired target temperature, i.e., the failure to effectively improve the technical effect of heating the target water to the target temperature under different target water volumes. It can improve the richness of application scenarios and the robustness of water boiling control based on water volume analysis.

[0187] In this optional embodiment, as another optional implementation, such as Figure 4 As shown, the water boiling control device based on water volume analysis may further include:

[0188] The first judgment module 303 is used to determine whether the current heating power corresponding to the target water use is less than the maximum heating power before the determination module 301 determines the target water use volume based on the preset water volume analysis algorithm and the first temperature difference.

[0189] The aforementioned determining module 301 is also used to determine the compensation coefficient corresponding to the preset heating efficiency based on the difference between the maximum heating power and the current heating power when the first determining module 303 determines that the current heating power is less than the maximum heating power.

[0190] The update module 305 is used to update the preset heating efficiency based on the compensation coefficient.

[0191] The pressurization module 304 is used to increase the boiling water pressure according to the updated preset heating efficiency.

[0192] As can be seen, implementing this optional embodiment enables water boiling control based on water volume analysis. It can adjust the heating efficiency in real time by adjusting the boiling gas pressure based on the fluctuation of the current power, thereby compensating for the fluctuation of power. While effectively improving the water boiling efficiency, it reduces the impact of errors such as heating efficiency and power fluctuation under different environments. It can further improve the accuracy of determining the target heating time required to heat the target water to the target temperature under different target water volumes, thereby improving the accuracy of controlling the heating of the target water to the target temperature during the water boiling process. It can further improve the application scenarios and control robustness of water boiling control based on water volume analysis.

[0193] In another alternative embodiment, such as Figure 4 As shown, the water boiling control device based on water volume analysis may further include:

[0194] The acquisition module 306 is used to acquire the first temperature of the target water during the heating process;

[0195] The second judgment module 307 is used to determine whether the first temperature is greater than a preset temperature threshold.

[0196] The heating module 302 described above is also used to heat the target water to the target temperature according to the preset heating power when the second judgment module 307 determines that the first temperature is greater than the preset temperature threshold.

[0197] The aforementioned acquisition module 306 is also used to acquire a second temperature of the target water after the heating module 302 heats the target water to the target temperature;

[0198] The second judgment module 307 mentioned above is also used to determine whether the second temperature is lower than the target temperature;

[0199] The aforementioned determining module 301 is also used to determine the first temperature difference obtained by heating the target water under the maximum heating power and preset heating time when the second determining module 307 determines that the second temperature is less than the target temperature.

[0200] The first and second temperatures mentioned above can be collected in real time or periodically or non-periodically at a predetermined time point; the preset heating power mentioned above can be a preset non-maximum heating power.

[0201] As can be seen, implementing this optional embodiment can detect the temperature of the target water during the heating process. When the temperature reaches a certain preset threshold, it can be continuously heated with low power to achieve the purpose of heating compensation, rather than using coarse full-power heating, which further improves the accuracy of heating the target water to the target temperature under different target water volumes.

[0202] Meanwhile, the optional implementation can also detect the temperature of the target water after heating it to the target temperature. If the temperature of the target water is lower than the target temperature, step 201 of the present invention and its corresponding subsequent steps are re-executed. This can further improve the water boiling efficiency and the accuracy of heating the target water to the target temperature under different target water volumes, so as to ensure that the target water continuously maintains the target temperature required by the user, and improve the humanization, application scenario richness, control robustness and intelligence of the solution.

[0203] In this optional embodiment, as one possible implementation, the aforementioned preset heating power is determined by the following method:

[0204] The aforementioned determining module 301 is also used to determine the difference between the aforementioned first temperature and the aforementioned target temperature.

[0205] The aforementioned determining module 301 is also used to determine a target difference interval that matches the aforementioned difference in a preset set of difference intervals.

[0206] The aforementioned determining module 301 is also used to determine the corresponding preset heating power based on the aforementioned target difference range.

[0207] Each of the aforementioned preset difference intervals corresponds to a preset heating power, and the aforementioned difference intervals include multiple differences.

[0208] As can be seen, implementing this optional embodiment can provide different low-power heating compensation for the target water according to the different temperatures of the target water collected, so as to ensure the accuracy of heating the target water to the target temperature under different target water volumes, while further improving the boiling efficiency, and achieving mutual promotion of heating efficiency and heating accuracy.

[0209] In this optional embodiment, as another optional implementation, the above may further include the following operations:

[0210] The second judgment module 307 described above is also used to determine whether the current temperature of the target water is greater than a preset cooling threshold after the heating module 302 heats the target water according to the maximum heating power and the target heating time.

[0211] The heating module 302 described above is also used to control the preset cooling unit to cool the target water to the target temperature when the second judgment module 307 determines that the current temperature of the target water is greater than the preset cooling threshold.

[0212] As can be seen, implementing this optional embodiment can further adjust the current temperature of the target water to the target temperature based on the actual heating of the target water. The adjustment method may include cooling. While improving the water boiling efficiency and further controlling the accuracy of the water boiling temperature, it can flexibly control the water boiling temperature to be adjusted multiple times according to the user's actual needs.
