Description

Technical Field

[0001] The present application relates to the field of intelligent control technology. Specifically, it relates to a boiling point adaptive heating control method, device and water dispenser for a water dispenser. Background Art

[0002] Existing water dispensers usually use a fixed boiling point temperature for heating control. However, the boiling point of water changes with the ambient air pressure. The heating method with a fixed boiling point temperature may cause inaccurate heating temperature in different air pressure environments. For example, in a low air pressure environment, the actual boiling point of water decreases. If the fixed boiling point temperature is still used for heating, it will result in insufficient heating. On the contrary, in a high air pressure environment, the actual boiling point of water increases. If the fixed boiling point temperature is still used for heating, it will cause overheating. In addition, existing water dispensers often use a full-power heating mode. Although it can quickly heat the water to boiling, the full-power heating method easily promotes the precipitation of minerals in the water, generating a large amount of scale, and also causing waste of energy.

[0003] In response to the above problems, there is currently no effective technical solution. Summary of the Invention

[0004] The purpose of the present application is to provide a boiling point adaptive heating control method, device and water dispenser for a water dispenser, to overcome the defect of the fixed boiling point temperature of traditional water dispensers, reduce energy waste and reduce the generation of scale.

[0005] In a first aspect, the present application provides a boiling point adaptive heating control method for a water dispenser, which is applied to a water dispenser having a barometric pressure detection component for collecting the ambient air pressure value. The method includes the following steps:

[0007] S2. Control the heating device to heat the drinking water in a high-power mode until the temperature of the drinking water reaches a preset first temperature threshold;

[0008] S3. After the temperature of the drinking water reaches the first temperature threshold, control the heating device to continue heating the drinking water in a low-power mode until the temperature of the drinking water reaches the boiling point temperature.

[0009] The boiling point adaptive heating control method of the water dispenser in this application first obtains the ambient air pressure value to adaptively determine the boiling point temperature of the drinking water according to the ambient air pressure value, overcoming the defect of the fixed boiling point temperature of the traditional water dispenser and ensuring the accuracy of the boiling point temperature in different air pressure environments. In terms of the heating process control, the boiling point adaptive heating control method of the water dispenser in this application adopts a two-stage heating strategy. This two-stage heating control method reduces energy consumption while ensuring the heating efficiency and reduces the scale generated due to violent boiling, thus realizing more accurate, efficient and healthy heating control of the water dispenser.

[0012] S22. Adjust the first temperature threshold according to the water quality hardness data, wherein the water quality hardness data is negatively correlated with the adjusted first temperature threshold;

[0013] S23. Heat the drinking water in the high-power mode until the temperature of the drinking water reaches the adjusted first temperature threshold.

[0014] By introducing the water quality hardness data in step S2, the first temperature threshold can be dynamically compensated and adjusted based on the water quality hardness data, enabling the heating control method to adapt to different water quality conditions to further reduce the generation of scale.

[0015] The described boiling point adaptive heating control method of the water dispenser, wherein step S22 includes:

[0016] S221. Determine the water quality hardness level corresponding to the water quality hardness data, and determine the corresponding first temperature threshold adjustment amount according to the water quality hardness level;

[0017] S222. Adjust the first temperature threshold according to the first temperature threshold adjustment amount.

[0018] The boiling point adaptive heating control method of the water dispenser in this application converts the water quality hardness data into the water quality hardness level through step S221, and then determines the first temperature threshold adjustment amount based on the water quality hardness level. This processing method can discretize the continuous water quality hardness data, making the adjustment of the temperature threshold more refined and controllable, making the adjustment process clearer and controllable, improving the accuracy and efficiency of the adjustment, and thus enhancing the performance of the heating control of the water dispenser.

[0033] Judge whether the absolute value of the difference between the updated first temperature threshold adjustment amount and the initial first temperature threshold adjustment amount exceeds a preset threshold;

[0034] If it exceeds the preset threshold, use the updated first temperature threshold adjustment amount to adjust the first temperature threshold, otherwise adjust the first temperature threshold with the initial first temperature threshold adjustment amount.

[0035] The described boiling point adaptive heating control method for a water dispenser, wherein in step S22, the first temperature threshold before adjustment is determined based on the following method:

[0036] Determine the first temperature threshold according to the water quality hardness data, the boiling point temperature, and a preset temperature mapping relationship. The temperature mapping relationship is the mapping relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water quality hardness data. Among them, the water quality hardness is positively correlated with the temperature difference between the boiling point temperature and the first temperature threshold.

[0037] The described boiling point adaptive heating control method for a water dispenser, wherein the boiling point adaptive heating control method for the water dispenser further includes a step executed after step S3:

[0038] S4. Control the heating device to maintain heating in a low power mode so that the drinking water boils at the boiling point temperature for a preset duration, where the preset duration increases as the boiling point temperature decreases.

[0039] In a second aspect, the present application also provides a boiling point adaptive heating control device for a water dispenser, which is applied to a water dispenser having a pressure detection component for collecting ambient air pressure values. The device includes:

[0040] An air pressure acquisition module for acquiring the ambient air pressure value;

[0041] A boiling point determination module for determining the boiling point temperature of the drinking water according to the ambient air pressure value;

[0042] A first heating module for controlling the heating device to heat the drinking water in a high power mode until the temperature of the drinking water reaches a preset first temperature threshold;

[0043] A second heating module for, after the temperature of the drinking water reaches the first temperature threshold, controlling the heating device to continue heating the drinking water in a low power mode until the temperature of the drinking water reaches the boiling point temperature.

[0044] The boiling point adaptive heating control device for the water dispenser of the present application first acquires the ambient air pressure value to adaptively determine the boiling point temperature of the drinking water according to the ambient air pressure value, overcomes the defect of the fixed boiling point temperature of the traditional water dispenser, and ensures the accuracy of the boiling point temperature in different air pressure environments. In terms of the heating process control, the boiling point adaptive heating control device for the water dispenser of the present application adopts a two-stage heating strategy. This two-stage heating control method ensures the heating efficiency while reducing energy consumption and reducing the scale generated due to violent boiling, thereby realizing more accurate, more efficient, and healthier heating control of the water dispenser.

[0045] In a third aspect, the present application also provides a water dispenser, which includes:

[0046] A heating device for heating drinking water;

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0058] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for differential description and cannot be understood as indicating or implying relative importance.

[0059] In a first aspect, please refer to Figure 1 and Figure 2 , some embodiments of the present application provide a boiling point adaptive heating control method for a water dispenser, which is applied to a water dispenser having a barometric pressure detection component for collecting ambient barometric pressure values. The method includes the following steps:

[0060] S1. Determine the boiling point temperature of the drinking water according to the ambient barometric pressure value;

[0061] S2. Control the heating device to heat the drinking water in a high-power mode until the temperature of the drinking water reaches a preset first temperature threshold;

[0062] S3. After the temperature of the drinking water reaches the first temperature threshold, control the heating device to continue heating the drinking water in a low-power mode until the temperature of the drinking water reaches the boiling point temperature.

[0063] Specifically, the ambient barometric pressure value is obtained based on the collection by the barometric pressure detection component, and the barometric pressure detection component can be a barometric pressure sensor installed inside or outside the water dispenser.

[0064] More specifically, in step S1, the determination of the boiling point temperature is based on the known physical relationship between barometric pressure and boiling point temperature. The step of determining the boiling point temperature of the drinking water can look up the boiling point temperature according to the ambient barometric pressure value based on a pre-established barometric pressure-boiling point correspondence table, or can calculate the boiling point temperature according to the ambient barometric pressure value based on a pre-established mathematical model (such as the Clausius-Clapeyron equation).

[0065] It should be noted that a water dispenser generally comes with a temperature sensor. Steps S2 and S3 are based on the actual temperature of the drinking water collected in real time by the temperature sensor to determine whether the heating device needs to switch the heating mode.

[0066] More specifically, in step S2, the first temperature threshold can be a preset value or a value dynamically adjusted according to the boiling point temperature. It can be set to a value slightly lower than the boiling point temperature, and its specific value can be adjusted according to actual needs. The boiling point adaptive heating control method of the water dispenser in the embodiment of the present application is based on the first temperature threshold as the mode switching benchmark between the high-power mode for rapid heating and the low-power mode for reducing the amount of scale caused by violent boiling, which can reduce energy consumption and reduce the scale generated by violent boiling while ensuring efficient heating.

[0067] More specifically, heating the drinking water in the low-power mode in step S3 can slow down the heating rate, avoid overshoot of the water temperature, and also help reduce the generation of scale.

[0068] More specifically, the high-power mode and the power mode are preset heating modes that can be selected by the heating device in the water dispenser. The main difference between the two is the selected heating power. Among them, the heating power selected in the high-power mode is higher than the heating power selected in the power mode, and its specific power parameters can be selected and adjusted according to actual needs and the water dispenser model.

[0069] The boiling point adaptive heating control method of the water dispenser in the embodiment of the present application first obtains the ambient air pressure value to adaptively determine the boiling point temperature of the drinking water according to the ambient air pressure value, overcomes the defect of the fixed boiling point temperature of the traditional water dispenser, and ensures the accuracy of the boiling point temperature in different air pressure environments. In terms of heating process control, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application adopts a two-stage heating strategy: First, quickly heat the drinking water to the preset first temperature threshold in the high-power mode to achieve rapid heating. After reaching the first temperature threshold, switch to the low-power mode and continue heating to the boiling point temperature. This two-stage heating control method reduces energy consumption and reduces the scale generated by violent boiling while ensuring the heating efficiency, thus realizing more accurate, efficient, and healthy heating control of the water dispenser.

[0070] In some preferred embodiments, step S1 includes:

[0071] Query the preset air pressure-boiling point correspondence table according to the ambient air pressure value;

[0072] In the air pressure-boiling point correspondence table, find the boiling point temperature matching the ambient air pressure value;

[0073] If there is no air pressure value in the air pressure - boiling point correspondence table that exactly matches the ambient air pressure value, the linear interpolation method is used to calculate the boiling point temperature.

[0074] Specifically, the preset air pressure - boiling point correspondence table represents the correspondence between the air pressure value and the boiling point temperature of drinking water. When the boiling point temperature needs to be determined, first, the current ambient air pressure value is obtained. Then, the system performs a query operation. If a completely matching air pressure value is found, the corresponding boiling point temperature in the table is directly read, and thus, the boiling point temperature can be quickly determined. Considering that in practical applications, the ambient air pressure value may change continuously, and it is impossible for the table to contain all possible air pressure values. Therefore, when no record that exactly matches the current ambient air pressure value is found in the air pressure - boiling point correspondence table, the boiling point adaptive heating control method for the water dispenser in the embodiments of the present application uses the linear interpolation method to calculate the boiling point temperature. The specific process may be: select two air pressure values adjacent to the current ambient air pressure value in the air pressure - boiling point correspondence table, and obtain the boiling point temperatures corresponding to these two air pressure values respectively. Then, based on the linear interpolation formula, use these four values to calculate the boiling point temperature corresponding to the current ambient air pressure value.

[0075] More specifically, the boiling point adaptive heating control method for the water dispenser in the embodiments of the present application can quickly obtain the boiling point temperature for the existing ambient air pressure value through the table - lookup method, and can still obtain the boiling point temperature when the air pressure value is not accurately recorded in the table through the linear interpolation method. Thus, the accuracy and efficiency of determining the boiling point temperature are ensured. This processing method combines the advantages of the quickness of table - lookup and the accuracy of linear interpolation, and can effectively and accurately determine the boiling point temperature of drinking water according to the ambient air pressure value, providing accurate boiling point temperature parameters for the subsequent heating control of the water dispenser.

[0076] In some preferred embodiments, step S2 includes:

[0077] S21. Obtain the water quality hardness data of the drinking water;

[0078] S22. Adjust the first temperature threshold according to the water quality hardness data, where the water quality hardness data is negatively correlated with the adjusted first temperature threshold;

[0079] S23. Heat the drinking water in the high - power mode until the temperature of the drinking water reaches the adjusted first temperature threshold.

[0080] Specifically, the water quality hardness data can be collected by a water quality hardness sensor installed inside the water dispenser. The water quality hardness sensor can be installed in the water tank of the drinking water to measure the water quality hardness data of the heated or to-be-heated drinking water. It can also be installed in the water delivery pipeline of the drinking water to measure the water quality hardness data of the transported drinking water. Its specific type selection can be a conductivity sensor or a dedicated water quality hardness sensor, etc.; in some other embodiments, the water quality hardness data can also be data input by the user.

[0081] More specifically, drinking water with higher water quality hardness is more likely to produce scale under the same heating conditions. In order to further reduce the formation of scale, the boiling point adaptive heating control method of the water dispenser according to the embodiments of the present application compensates and adjusts the first temperature threshold based on the water quality hardness data of the drinking water to further optimize the heating quality of the drinking water and improve the user experience. The specific process is as follows: in step S22, when the water quality hardness is high, the first temperature threshold is lowered; when the water quality hardness is low, the first temperature threshold is raised or kept unchanged; thus, by introducing the water quality hardness data in step S2, the first temperature threshold can be dynamically compensated and adjusted based on the water quality hardness data, so that the heating control method can adapt to different water quality conditions to further reduce the formation of scale.

[0082] More specifically, the adjustment process of the first temperature threshold in step S22 can be implemented through a preset query table or mathematical model, so that the target temperature during the high-power heating process in step S23 is no longer a fixed value, but the first temperature threshold dynamically compensated and adjusted according to the water quality hardness, enabling the water dispenser to adaptively adjust the upper limit of the high-power heating temperature according to different water quality hardnesses, so as to inhibit the formation of scale to a certain extent, optimize the heating efficiency, and improve the user experience.

[0083] In some preferred embodiments, step S22 includes:

[0084] S221. Determine the water quality hardness level corresponding to the water quality hardness data, and determine the corresponding first temperature threshold adjustment amount according to the water quality hardness level;

[0085] S222. Adjust the first temperature threshold according to the first temperature threshold adjustment amount.

[0086] Specifically, in step S221, the water quality hardness data is first converted into a water quality hardness level, and this conversion process can be implemented through a preset grading standard. For example, the water quality hardness data can be divided into multiple levels such as soft, medium, hard, and extremely hard, and each water quality hardness level is preset with a corresponding first temperature threshold adjustment amount.

[0087] More specifically, in the boiling point adaptive heating control method of the water dispenser according to the embodiments of the present application, the water quality hardness data is converted into a water quality hardness level through step S221, and then the first temperature threshold adjustment amount is determined based on the water quality hardness level. This processing method can discretize the continuous water quality hardness data, making the adjustment of the temperature threshold more refined and controllable, making the adjustment process clearer and controllable, improving the accuracy and efficiency of the adjustment, and thus enhancing the performance of the water dispenser heating control.

[0088] In some preferred embodiments, step S222 includes:

[0089] S2211. Based on the initial water quality hardness data obtained at the start of heating, determine the initial water quality hardness level;

[0090] S2212. Based on the initial water quality hardness level, determine the initial first temperature threshold adjustment amount;

[0091] S2213. During the heating process, obtain the water quality hardness data again at a preset time interval or a preset temperature interval;

[0092] S2214. Based on the water quality hardness data obtained again, determine the updated water quality hardness level;

[0093] S2215. Based on the updated water quality hardness level, determine the updated first temperature threshold adjustment amount;

[0094] S2216. Based on the initial first temperature threshold adjustment amount or the updated first temperature threshold adjustment amount, adjust the first temperature threshold.

[0095] Specifically, the process of obtaining the water quality hardness level in steps S2211 and S2214 is the same as the foregoing content, so it will not be elaborated here; the mapping relationship between the water quality hardness level and the water quality hardness data can be non-linear to more finely distinguish the water quality in different hardness intervals.

[0096] More specifically, in step S2212, the initial first temperature threshold adjustment amount can be determined by looking up a preset corresponding relationship table according to the initial water quality hardness level. The corresponding relationship table records the mapping relationship between the water quality hardness level and the first temperature threshold adjustment amount; similarly, in step S2215, the updated first temperature threshold adjustment amount can be determined by looking up a preset corresponding relationship table according to the updated water quality hardness level.

[0097] More specifically, in step S2213, the preset time interval can be set to 1 minute, 2 minutes, etc., and the preset temperature interval can be set to 10 degrees Celsius, 20 degrees Celsius, etc.

[0098] More specifically, in step S2216, adjusting the first temperature threshold may be adding the initial first temperature threshold adjustment amount to the initial first temperature threshold, or adding the updated first temperature threshold adjustment amount to the initial first temperature threshold.

[0099] As a preferred embodiment, step S2216 may compare whether the difference between the updated first temperature threshold adjustment amount and the initial first temperature threshold adjustment amount is too large. If it exceeds the difference, it indicates that the change in water quality hardness is relatively obvious. At this time, the updated first temperature threshold adjustment amount is used to adjust the first temperature threshold. Otherwise, it is considered that the change in water quality hardness is not significant, and the initial first temperature threshold adjustment amount is still used for adjustment. Thus, the minor fluctuations in the water quality hardness data can be effectively filtered out, and it is possible to avoid making overly sensitive responses and frequently adjusting the temperature threshold due to slight fluctuations in water quality hardness, thereby ensuring the stability and reliability of the heating control process.

[0100] The boiling point adaptive heating control method for the water dispenser according to the embodiment of the present application can effectively solve the problem of inaccurate adjustment of the first temperature threshold due to changes in water quality hardness by dynamically monitoring the water quality hardness during the heating process and dynamically adjusting the first temperature threshold according to the change in water quality hardness, ensuring the accuracy of heating control, realizing the dynamic adjustment of the first temperature threshold according to the change in water quality hardness, and further optimizing the heating control process.

[0101] In some preferred embodiments, step S2212 includes:

[0102] Calculating an initial first temperature threshold adjustment amount based on a preset adjustment value function according to the initial water quality hardness level. The adjustment value function is:

[0103] ΔT1 = k * HL + b (1)

[0104] Wherein, ΔT1 is the first temperature threshold adjustment amount, HL is the water quality hardness level, k is the slope coefficient, indicating the change amplitude of the water quality hardness level acting on the initial first temperature threshold adjustment amount, and b is the intercept, indicating the first temperature threshold adjustment amount when the water quality hardness level is 0.

[0105] Specifically, the slope coefficient k and the intercept b are preset parameters and can be set according to usage requirements; the slope coefficient k determines the influence degree of the water quality hardness level on the first temperature threshold adjustment amount ΔT1. In the embodiment of the present application, the slope coefficient k is preferably a negative value, and the corresponding first temperature threshold is also a negative value. Therefore, the higher the water quality hardness level, the smaller the corresponding determined first temperature threshold, and the adjusted first temperature threshold can be made smaller.

[0106] More specifically, the intercept b is the reference value of the initial first temperature threshold adjustment amount when the water quality hardness level HL is 0.

[0107] More specifically, the first temperature threshold adjustment amount is provided with a lower limit value, which can effectively prevent the adjustment amount of the first temperature threshold from being too large, resulting in the premature switching of the high-power mode to the low-power mode and affecting the heating treatment efficiency.

[0108] It should be noted that in step S2215, the updated water quality hardness level can be substituted into formula (1) to determine the updated first temperature threshold adjustment amount.

[0109] More specifically, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application uses an adjustment value function with linear characteristics to calculate the initial first temperature threshold adjustment amount and the updated first temperature threshold adjustment amount, and can efficiently determine the dynamic adjustment value required for the first temperature threshold, providing a basis for the subsequent adjustment of the first temperature threshold.

[0110] In some preferred embodiments, step S2213 includes:

[0111] Obtain the current heating power;

[0112] Judge whether the current heating power is greater than the preset power threshold;

[0113] If the current heating power is greater than the preset power threshold, set the preset time interval or the preset temperature interval as the first interval;

[0114] If the current heating power is not greater than the preset power threshold, set the preset time interval or the preset temperature interval as the second interval. The first interval and the second interval are of the same type, and the second interval is greater than the first interval;

[0115] Obtain the water quality hardness data again according to the set preset time interval or preset temperature interval.

[0116] Specifically, the current heating power is the heating power used in the current high-power mode, which can be obtained in real time through a power detection device such as a current sensor or a voltage sensor;

[0117] More specifically, the process of setting the preset time interval or the preset temperature interval as the first interval is to assign the value of the preset first interval to the preset time interval or the preset temperature interval, and the process of setting the preset time interval or the preset temperature interval as the second interval is to assign the value of the preset second interval to the preset time interval or the preset temperature interval. Therefore, these steps are actually to configure one of the preset first interval and the second interval to the preset time interval or the preset temperature interval.

[0118] More specifically, during actual use, the heating power in the high-power mode may vary due to environmental conditions, power supply conditions, and device losses, generally showing a value lower than the rated thermal power preset at the factory. During the heating process of the water dispenser, the magnitude of the heating power affects the rate of change of water quality hardness. When the water dispenser is in the high-power heating state, the water temperature rises rapidly, the precipitation rate of minerals in the water accelerates, and scale is likely to form quickly, resulting in a relatively rapid change in water quality hardness. Conversely, when the water dispenser is in the low-power heating state, the rate of water temperature rise slows down, and the change in water quality hardness is relatively slow. Therefore, to obtain water quality hardness data more efficiently and accurately, the above steps dynamically adjust the acquisition interval of water quality hardness data according to the relationship between the current heating power and the preset power threshold. The preset power threshold is a pre-set reference value, which can be the rated thermal power preset at the factory in the high-power mode, or slightly less than this rated power, such as set to 90% of the rated power, preferably the latter. The specific implementation process of the above adjustment process: obtain the current heating power of the water dispenser, and then determine whether the current heating power is greater than the preset power threshold to judge whether the heating power in the high-power mode of the water dispenser meets the rated power. If the current heating power is greater than the preset power threshold, it indicates that the water dispenser is in the high-power heating state. At this time, set a shorter first interval as the interval for obtaining water quality hardness data again to obtain water quality hardness data relatively frequently and timely reflect the change in water quality hardness. On the contrary, if the current heating power is not greater than the preset power threshold, it indicates that the heating power in the high-power mode of the water dispenser is in an underpower state. At this time, set a longer second interval as the interval for obtaining water quality hardness data again to reduce the acquisition frequency of water quality hardness data and reduce system resource consumption. Thus, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application can dynamically adjust the acquisition frequency of water quality hardness data according to the actual use situation in the high-power mode, improve the data acquisition efficiency, optimize the system performance, and reduce unnecessary system resource occupation on the premise of ensuring the timeliness of water quality hardness data update.

[0119] More specifically, the specific type of the time interval or temperature interval can be selected according to the actual application scenario and system requirements. For example, in a scenario where precise control of the heating process is required, a temperature interval can be selected; in a scenario with high requirements for time response, a time interval can be selected.

[0120] In some preferred embodiments, step S2216 includes:

[0121] Determine whether the absolute value of the difference between the updated first temperature threshold adjustment amount and the initial first temperature threshold adjustment amount exceeds a preset threshold;

[0122] If it exceeds the preset threshold, the first temperature threshold is adjusted using the updated first temperature threshold adjustment amount; otherwise, the first temperature threshold is adjusted using the initial first temperature threshold adjustment amount.

[0123] Specifically, the above steps introduce a preset threshold as the selection criterion for the initial first temperature threshold adjustment amount and the updated first temperature threshold adjustment amount; if the absolute value of the difference between the updated first temperature threshold adjustment amount and the initial first temperature threshold adjustment amount exceeds the preset threshold, it indicates that the water quality hardness has changed significantly, and step S2216 will adjust the first temperature threshold using the updated first temperature threshold adjustment amount. Conversely, if the absolute value of the difference does not exceed the preset threshold, it indicates that the change in water quality hardness is small. To ensure the stability of heating control, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application will maintain the adjustment of the first temperature threshold using the initial first temperature threshold adjustment amount; through this processing method, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application can effectively avoid frequent adjustment of the temperature threshold caused by slight fluctuations in water quality hardness data, thereby improving the stability of heating control.

[0124] In some preferred embodiments, in step S22, the first temperature threshold before adjustment is determined based on the following method:

[0125] The first temperature threshold is determined according to the water quality hardness data, the boiling point temperature, and a preset temperature mapping relationship. The temperature mapping relationship is the mapping relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water quality hardness data, where the water quality hardness is positively correlated with the temperature difference between the boiling point temperature and the first temperature threshold.

[0126] Specifically, the temperature mapping relationship describes the change relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water quality hardness data; since when the water dispenser is in a high-power heating state, the water temperature rises rapidly, the precipitation rate of minerals in the water accelerates, and scale is easily generated quickly, and the water quality hardness changes relatively fast, and the mineral precipitation rate is faster closer to the boiling point temperature, and the water quality hardness data is more likely to precipitate minerals, so the temperature mapping relationship of the present application sets the temperature difference between the boiling point temperature and the first temperature threshold to be positively correlated with the water quality hardness, that is, the higher the water quality hardness data, the greater the temperature difference between the boiling point temperature and the first temperature threshold. Conversely, the lower the water quality hardness data, the smaller the temperature difference between the boiling point temperature and the first temperature threshold. Thus, for water with a higher water quality hardness, the first temperature threshold will be set relatively lower than the boiling point temperature, so that the water dispenser can switch to the low-power mode earlier when the water quality hardness is high.

[0127] More specifically, the water dispenser can adaptively set the original first temperature threshold that is not compensated and adjusted based on step S2216 according to the water quality hardness, and can accurately obtain a reliable first temperature threshold in combination with step S2216.

[0128] More specifically, in the embodiments of the present application, since the first temperature threshold is set according to the water quality hardness dynamics and the boiling point temperature, for water with a higher water quality hardness, the first temperature threshold will be set to a temperature with a greater difference from the boiling point temperature, so that the water dispenser can switch to the low-power mode earlier, thereby effectively reducing the generation of water scale while ensuring the heating efficiency.

[0129] In some preferred embodiments, the temperature mapping relationship is:

[0130] T diff = c * ln(WH + d) + e (2)

[0131] Wherein, ln is the natural logarithm, c is the coefficient of the logarithmic term, representing the influence degree of the logarithmic term on the temperature difference, c>0; d is the water quality hardness offset, used to adjust the starting point of the logarithmic function, d≥0; e is the temperature difference reference offset, representing the temperature difference reference when the water quality hardness is zero, e≥0, T diff is the temperature difference between the boiling point temperature and the first temperature threshold, WH is the water quality hardness data, and c, d, and e are all preset parameters;

[0132] The process of determining the first temperature threshold according to the water quality hardness data, the boiling point temperature, and the preset temperature mapping relationship includes:

[0133] Calculating and obtaining the temperature difference based on the water quality hardness data and the temperature mapping relationship;

[0134] Calculating and obtaining the first temperature threshold based on the following formula according to the temperature difference and the boiling point temperature:

[0135] T1 = T boil - T diff ,T boil is the boiling point temperature, and T1 is the first temperature threshold.

[0136] Specifically, the natural logarithm ln in the formula is used to construct the mapping relationship between the water quality hardness data WH and the temperature difference T diff between them. The parameter c is the coefficient of the logarithmic term, used to adjust the influence degree of the logarithmic term on the temperature difference. The parameter d is the water quality hardness offset, used to adjust the starting point of the logarithmic function. The parameter e is the temperature difference reference offset, representing the temperature difference reference when the water quality hardness is zero. These preset parameters c, d, and e enable the temperature mapping relationship curve to be flexibly adjusted according to the actual application scenario to meet the requirements of different water qualities and water dispenser designs.

[0137] More specifically, the boiling point adaptive heating control method of the water dispenser according to the embodiments of the present application constructs a temperature mapping relationship by using a logarithmic function, and combines the set parameters c, d, and e to accurately describe the influence of water quality hardness on the first temperature threshold, can more accurately describe the influence of water quality hardness data on the first temperature threshold, thereby more accurately determining the first temperature threshold, and further improving the heating control effect of the water dispenser under different water quality conditions. While ensuring the heating efficiency of drinking water, it can also effectively reduce the formation of water scale.

[0138] In some preferred embodiments, the boiling point adaptive heating control method of the water dispenser further includes steps executed after step S3:

[0139] S4. Control the heating device to maintain heating in a low power mode so that the drinking water boils at the boiling point temperature for a preset duration, where the preset duration increases as the boiling point temperature decreases.

[0140] Specifically, for the continuous boiling step, the boiling point adaptive heating control method of the water dispenser according to the embodiments of the present application is carried out in a low power mode, aiming to reduce energy consumption and reduce the generation of water scale while maintaining the boiling state. Among them, the preset duration is set to be associated with the boiling point temperature, mainly manifested as when the boiling point temperature decreases, the preset duration increases; this setting is considered that at a lower boiling point temperature, the boiling degree of water weakens, so a longer boiling time is required to ensure that the drinking water is fully treated. As an implementation method, the preset duration can be determined based on experimental data or empirical formulas. This boiling heating method not only ensures the drinking safety of the drinking water but also avoids the energy waste caused by unnecessary long-term heating.

[0141] In some embodiments, the preset duration is determined by looking up a preset boiling duration adjustment table, and the boiling duration adjustment table records multiple boiling point temperature values and the corresponding preset boiling durations for each boiling point temperature value.

[0142] In some preferred embodiments, step S4 includes:

[0143] S41. Calculate the preset duration required for boiling according to the exponential function model, where the exponential function model is:

[0144] T duration =f⋅exp(g⋅(T boil_ref −T boil ))+T base (3)

[0145] where f is a proportionality coefficient, f > 0, g is an exponential coefficient, g > 0, T base is the basic boiling duration, T base > 0, T boil_refis the reference boiling point temperature, T duration is the preset duration, and exp is the exponential function;

[0146] S42. Based on the preset duration, control the heating device to maintain heating in the low - power mode when the drinking water is in the boiling state.

[0147] Specifically, in step S41, the proportionality coefficient f, the exponential coefficient g, the base boiling duration T base and the reference boiling point temperature T boil_ref are all pre - set parameters; the proportionality coefficient f is used to adjust the amplitude of the exponential function, and the exponential coefficient g is used to control the rate of change of the boiling duration with the boiling point temperature. The base boiling duration T base ensures that there is a minimum boiling time even at relatively high boiling point temperatures. The reference boiling point temperature T boil_ref is a reference value used to compare with the boiling point temperature T boil The exponential function ensures that the boiling duration increases non - linearly as the boiling point temperature decreases, more precisely matching the actual boiling requirements. The specific values of these parameters can be experimentally adjusted and optimized according to the actual water dispenser model, heating performance, and user requirements for the boiling effect.

[0148] More specifically, in this embodiment, the low - power mode is adopted to avoid over - heating and energy waste while maintaining the boiling state. The heating duration for maintaining boiling is determined by T duration which ensures that at different boiling point temperatures, the drinking water can be fully boiled for the preset duration. In this way, the water dispenser can accurately control the boiling duration according to the actual boiling point temperature, ensuring both the drinking safety of the drinking water and avoiding unnecessary energy consumption.
