Description

Technical Field

[0001] The present application relates to the field of intelligent control technology, and in particular to a method and device for adaptively controlling boiling point heating of a water dispenser, and 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 will change with the change of ambient air pressure. The heating method with a fixed boiling point temperature will lead to inaccurate heating temperature under different air pressure environments. For example, in a low-pressure environment, the actual boiling point of water decreases. If a fixed boiling point temperature is still used for heating, it will lead to insufficient heating; conversely, in a high-pressure environment, the actual boiling point of water increases. If a fixed boiling point temperature is still used for heating, it will lead to overheating. In addition, existing water dispensers often use a full-power heating mode. Although it can quickly heat water to boiling, the full-power heating method easily causes minerals to precipitate in the water, generating a large amount of scale, and also causes energy waste.

[0003] There is currently no effective technical solution to the above problems. Summary of the invention

[0004] The purpose of the present application is to provide a method, device and water dispenser for adaptively controlling boiling point heating of a water dispenser, so as to overcome the defects of fixed boiling point temperature of traditional water dispensers, reduce energy waste and reduce scale formation.

[0005] In a first aspect, the present application provides a method for adaptively controlling boiling point heating of a water dispenser, which is applied to a water dispenser having an air pressure detection component for collecting ambient air pressure values, and the method comprises the following steps: S1. Determine the boiling point of drinking water according to the ambient air pressure value; S2, 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; 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.

[0006] The water dispenser boiling point adaptive heating control method of the present application first obtains the ambient air pressure value to adaptively determine the boiling point temperature of 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 under different air pressure environments. In terms of heating process control, the water dispenser boiling point adaptive heating control method of the present application adopts a two-stage heating strategy. This two-stage heating control method reduces energy consumption while ensuring heating efficiency, and reduces scale generated by violent boiling, thereby achieving more accurate, more efficient, and healthier water dispenser heating control.

[0007] The water dispenser boiling point adaptive heating control method, wherein step S2 comprises: S21.

[0010] The water dispenser boiling point adaptive heating control method of the present application converts the water hardness data into a water hardness level through step S221, and then determines the first temperature threshold adjustment amount based on the water hardness level. This processing method can discretize the continuous water 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 thereby improving the performance of the water dispenser heating control.

[0012] The water dispenser boiling point adaptive heating control method, wherein step S2213 comprises: Get the current heating power; Determining whether the current heating power is greater than a preset power threshold; If the current heating power is greater than the preset power threshold, setting the preset time interval or preset temperature interval as a first interval; If the current heating power is not greater than the preset power threshold, setting the preset time interval or the preset temperature interval to a second interval, the first interval and the second interval are of the same type, and the second interval is greater than the first interval; The water hardness data is obtained again according to the preset time interval or preset temperature interval.

[0013] The water dispenser boiling point adaptive heating control method, wherein step S2216 comprises: Determining 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; If the temperature 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.

[0014] In the water dispenser boiling point adaptive heating control method, in step S22, the first temperature threshold before adjustment is determined based on the following method: A first temperature threshold is determined based on the water hardness data, boiling point temperature and a preset temperature mapping relationship, wherein the temperature mapping relationship is a mapping relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water hardness data, wherein the water hardness is positively correlated with the temperature difference between the boiling point temperature and the first temperature threshold.

[0015] The water dispenser boiling point adaptive heating control method, wherein the water dispenser boiling point adaptive heating control method further includes the following steps performed after step S3: 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 time, wherein the preset time increases as the boiling point temperature decreases.

[0016] In a second aspect, the present application further provides a water dispenser boiling point adaptive heating control device, which is applied to a water dispenser having an air pressure detection component for collecting ambient air pressure values, and the device comprises: Air pressure acquisition module, used to obtain the ambient air pressure value; A boiling point determination module, used to determine the boiling point temperature of drinking water according to the ambient air pressure value; a first heating module, used to 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; The second heating module is used to control the heating device to continue heating the drinking water in a low power mode after the temperature of the drinking water reaches the first temperature threshold, until the temperature of the drinking water reaches the boiling point.

[0017] The boiling point adaptive heating control device of the water dispenser 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, thus overcoming the defect of the fixed boiling point temperature of the traditional water dispenser and ensuring the accuracy of the boiling point temperature under different air pressure environments. In terms of heating process control, the boiling point adaptive heating control device of the water dispenser of the present application adopts a two-stage heating strategy. This two-stage heating control method reduces energy consumption while ensuring heating efficiency, and reduces scale generated by violent boiling, thereby achieving more accurate, more efficient and healthier heating control of the water dispenser.

[0018] In a third aspect, the present application further provides a water dispenser, comprising: Heating device for heating drinking water; Air pressure detection component, used to collect ambient air pressure values; The controller is electrically connected to the heating device and the air pressure detection component, and is used to execute the steps in the boiling point adaptive heating control method of the water dispenser provided in the first aspect to control the heating device to heat the drinking water.

[0019] The water dispenser of the present application can automatically adapt to the boiling point to heat drinking water, overcoming the defect of the traditional water dispenser with a fixed boiling point temperature, ensuring the accuracy of the boiling point temperature under different air pressure environments, and heating through a two-stage heating control method, thereby achieving more accurate, more efficient and healthier water dispenser heating control.

[0020] From the above, it can be seen that the present application provides a method, device and water dispenser for adaptively controlling the boiling point of a water dispenser, wherein the method for adaptively controlling the boiling point of a water dispenser can adaptively determine the boiling point temperature of drinking water according to the ambient air pressure value, thereby overcoming the defect of the fixed boiling point temperature of traditional water dispensers, and ensuring the accuracy of the boiling point temperature under different air pressure environments. At the same time, a two-stage heating strategy is adopted, which can reduce energy consumption while ensuring heating efficiency, and reduce scale generated by violent boiling, thereby achieving more accurate, more efficient and healthier heating control of water dispensers.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the 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 of the embodiments. The components of the embodiments of the present application described and shown in the 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 drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so 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 this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0029] First, please refer to Figure 1 and Figure 2 Some embodiments of the present application provide a method for controlling boiling point of a water dispenser by adaptive heating, which is applied to a water dispenser having an air pressure detection component for collecting ambient air pressure values, and the method comprises the following steps: S1. Determine the boiling point of drinking water according to the ambient air pressure value; S2, 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; 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.

[0030] Specifically, the ambient air pressure value is acquired based on the air pressure detection component, and the air pressure detection component can be an air pressure sensor installed inside or outside the water dispenser.

[0031] More specifically, in step S1, the boiling point temperature is determined based on the known physical relationship between air pressure and boiling point temperature. The step of determining the boiling point temperature of drinking water can look up the boiling point temperature based on the ambient air pressure value based on a pre-established air pressure-boiling point correspondence table, and can also calculate the boiling point temperature based on the ambient air pressure value based on a pre-established mathematical model (such as the Clausius-Clapeyron equation).

[0032] It should be noted that the water dispenser generally has a temperature sensor. Steps S2 and S3 are based on the temperature sensor to collect the actual temperature of the drinking water in real time to determine whether the heating device needs to switch the heating mode.

[0033] 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 for the water dispenser of the embodiment of the present application is based on the first temperature threshold for a high-power mode for rapid heating and a low-power mode for slowing down the amount of scale caused by violent boiling. The mode switching benchmark can reduce energy consumption and reduce scale caused by violent boiling while ensuring efficient heating.

[0034] More specifically, heating drinking water in low-power mode in step S3 can slow down the heating rate and avoid water temperature overshoot, while also helping to reduce the generation of scale.

[0035] More specifically, the high-power mode and the power mode are preset heating modes that can be selected for the heating device in the water dispenser. The main difference between the two is that different heating powers are selected. Among them, the heating power selected in the high-power mode is higher than the heating power selected in the power mode. The specific power parameters can be selected and adjusted according to actual needs and the water dispenser model.

[0036] The boiling point adaptive heating control method for a water dispenser in an 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, thereby overcoming the defect of the fixed boiling point temperature of a traditional water dispenser and ensuring the accuracy of the boiling point temperature under different air pressure environments. In terms of heating process control, the boiling point adaptive heating control method for a water dispenser in an embodiment of the present application adopts a two-stage heating strategy: first, the drinking water is quickly heated to a preset first temperature threshold in a high-power mode to achieve rapid temperature rise, and after reaching the first temperature threshold, it is switched to a low-power mode to continue heating to the boiling point temperature. This two-stage heating control method reduces energy consumption while ensuring heating efficiency, and reduces scale generated by violent boiling, thereby achieving more accurate, efficient, and healthier heating control of a water dispenser.

[0037] In some preferred embodiments, step S1 comprises: Query the preset pressure-boiling point correspondence table according to the ambient pressure value; In the pressure-boiling point correspondence table, find the boiling point temperature that matches the ambient pressure value; If there is no pressure value that exactly matches the ambient pressure value in the pressure-boiling point correspondence table, the boiling point temperature is calculated using linear interpolation.

[0038] Specifically, the preset air pressure-boiling point correspondence table characterizes 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, thereby quickly determining the boiling point temperature. Considering that in practical applications, the ambient air pressure value may change continuously, it is impossible for the table to contain all possible air pressure values. Therefore, when no record that completely matches the current ambient air pressure value is found in the air pressure-boiling point correspondence table, the boiling point adaptive heating control method of the drinking machine of the embodiment of the present application adopts a linear interpolation method to calculate the boiling point temperature, and the specific process can 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 each of the two air pressure values, and then calculate the boiling point temperature corresponding to the current ambient air pressure value using these four values ​​based on the linear interpolation formula.

[0039] More specifically, the boiling point adaptive heating control method for the water dispenser of the embodiment of the present application can quickly obtain the boiling point temperature for the existing ambient air pressure value by table lookup, and can still obtain the boiling point temperature by linear interpolation even if the air pressure value is not accurately recorded in the table, thereby ensuring the accuracy and efficiency of the boiling point temperature determination; this processing method combines the advantages of the rapidity 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, thereby providing accurate boiling point temperature parameters for subsequent water dispenser control heating.

[0040] In some preferred embodiments, step S2 comprises: S21. Obtaining water hardness data of drinking water; S22, adjusting the first temperature threshold according to the water hardness data, wherein the water hardness data is negatively correlated with the adjusted first temperature threshold; S23: Heat the drinking water in a high power mode until the temperature of the drinking water reaches the adjusted first temperature threshold.

[0041] Specifically, the water hardness data can be collected by a water hardness sensor installed inside the water dispenser. The water hardness sensor can be installed in a drinking water tank to measure the water hardness data of drinking water that is heated or to be heated. It can also be installed in a drinking water delivery pipeline to measure the water hardness data of drinking water in delivery. The specific type selected can be a conductivity sensor or a special water hardness sensor, etc.; in some other embodiments, the water hardness data can also be data entered by the user.

[0042] More specifically, drinking water with higher water hardness data is more likely to produce scale under the same heating conditions. In order to further reduce the formation of scale, the drinking water dispenser boiling point adaptive heating control method of the embodiment of the present application compensates and adjusts the first temperature threshold based on the water 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: in step S22, when the water hardness is higher, the first temperature threshold is lowered, and when the water hardness is lower, the first temperature threshold is increased or maintained unchanged; thus, by introducing water hardness data in step S2, the first temperature threshold can be dynamically compensated and adjusted based on the water hardness data, so that the heating control method can adapt to different water quality conditions to further reduce the formation of scale.

[0043] 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 of the heating in the high-power heating process in step S23 is no longer a fixed value, but the first temperature threshold adjusted according to dynamic compensation of the water hardness, so that the water dispenser can adaptively adjust the upper temperature limit of high-power heating according to different water hardness, so as to inhibit the formation of scale to a certain extent, optimize the heating efficiency, and improve the user experience.

[0044] In some preferred embodiments, step S22 includes: S221, determining a water hardness level corresponding to the water hardness data, and determining a corresponding first temperature threshold adjustment amount according to the water hardness level; S222: Adjust the first temperature threshold according to the first temperature threshold adjustment amount.

[0045] Specifically, in step S221, the water hardness data is first converted into water hardness levels. The conversion process can be achieved through a preset grade classification standard. For example, the water hardness data can be divided into multiple levels such as soft, medium, hard and extremely hard. Each water hardness level is pre-set with a corresponding first temperature threshold adjustment amount.

[0046] More specifically, the water dispenser boiling point adaptive heating control method of the embodiment of the present application converts the water hardness data into a water hardness level through step S221, and then determines the first temperature threshold adjustment amount based on the water hardness level. This processing method can discretize the continuous water 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 thereby improving the performance of the water dispenser heating control.

[0047] In some preferred embodiments, step S222 includes: S2211, determining an initial water hardness level based on the initial water hardness data obtained when heating starts; S2212, determining an initial first temperature threshold adjustment amount based on an initial water hardness level; S2213, during the heating process, obtaining water hardness data again at a preset time interval or a preset temperature interval; S2214, determining an updated water hardness level based on the water hardness data acquired again; S2215, determining an updated first temperature threshold adjustment amount based on the updated water hardness level; S2216: Adjust the first temperature threshold based on the initial first temperature threshold adjustment amount or the updated first temperature threshold adjustment amount.

[0048] Specifically, the process of obtaining the water hardness level in step S2211 and step S2214 is consistent with the above content, so it will not be repeated here; the mapping relationship between the water hardness level and the water hardness data can be nonlinear, so as to more finely distinguish the water quality in different hardness ranges.

[0049] More specifically, in step S2212, the initial first temperature threshold adjustment amount can be determined according to the initial water hardness level by searching a preset correspondence table, which records the mapping relationship between the water hardness level and the first temperature threshold adjustment amount; similarly, in step S2215, the updated first temperature threshold adjustment amount can be determined according to the updated water hardness level by searching a preset correspondence table.

[0050] 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.

[0051] More specifically, in step S2216, adjusting the first temperature threshold may be adding the initial first temperature threshold to the initial first temperature threshold adjustment amount, or adding the initial first temperature threshold to the updated first temperature threshold adjustment amount.

[0052] As a preferred implementation, step S2216 can compare whether the difference between the updated first temperature threshold adjustment amount and the initial first temperature threshold adjustment amount is too large. If the difference is too large, it indicates that the water hardness has changed significantly. At this time, the updated first temperature threshold adjustment amount is used to adjust the first temperature threshold. Otherwise, it is considered that the water hardness has not changed much, and the initial first temperature threshold adjustment amount is still used for adjustment. In this way, small fluctuations in the water hardness data can be effectively filtered out, and overly sensitive reactions due to slight fluctuations in water hardness and frequent adjustments of the temperature threshold can be avoided, thereby ensuring the stability and reliability of the heating control process.

[0053] The adaptive heating control method for boiling point of a water dispenser in the embodiment of the present application can effectively solve the problem of inaccurate adjustment of the first temperature threshold due to changes in water hardness by dynamically monitoring the water hardness during the heating process and dynamically adjusting the first temperature threshold according to changes in water hardness, thereby ensuring the accuracy of heating control and realizing dynamic adjustment of the first temperature threshold according to changes in water hardness, thereby further optimizing the heating control process.

[0054] In some preferred embodiments, step S2212 includes: The initial first temperature threshold adjustment amount is calculated based on the preset adjustment value function according to the initial water hardness level, and the adjustment value function is: ΔT1 = k * HL + b (1) Among them, ΔT1 is the first temperature threshold adjustment amount, HL is the water hardness level, k is the slope coefficient, which represents the change amplitude of the water hardness level on the initial first temperature threshold adjustment amount, and b is the intercept, which represents the first temperature threshold adjustment amount when the water hardness level is 0.

[0055] Specifically, the slope coefficient k and the intercept b are pre-set parameters and can be set according to usage requirements; the slope coefficient k determines the degree of influence of the water 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 hardness level, the smaller the corresponding first temperature threshold, which can make the adjusted first temperature threshold smaller.

[0056] More specifically, the intercept b is a reference value of the initial first temperature threshold adjustment amount when the water hardness level HL is 0.

[0057] More specifically, the first temperature threshold adjustment amount is set with a lower limit value, which can effectively prevent the adjustment amount of the first temperature threshold from being too large, causing the high power mode to switch to the low power mode too early and affecting the heating process efficiency.

[0058] It should be noted that, in step S2215, the updated water hardness level may be substituted into equation (1) to determine the updated first temperature threshold adjustment amount.

[0059] More specifically, the water dispenser boiling point adaptive heating control method of the embodiment of the present application utilizes an adjustment value function with linear characteristics to calculate the initial first temperature threshold adjustment amount and the updated first temperature threshold adjustment amount, which can efficiently determine the dynamic adjustment value required for the first temperature threshold and provide a basis for subsequent first temperature threshold adjustments.

[0060] In some preferred embodiments, step S2213 includes: Get the current heating power; Determine whether the current heating power is greater than a preset power threshold; If the current heating power is greater than the preset power threshold, setting the preset time interval or the preset temperature interval as the first interval; If the current heating power is not greater than the preset power threshold, the preset time interval or the preset temperature interval is set 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; The water hardness data is obtained again at the preset time interval or preset temperature interval.

[0061] Specifically, the current heating power is the heating power used in the currently used high power mode, which can be obtained in real time through a power detection device such as a current sensor or a voltage sensor; More specifically, the process of setting a preset time interval or a preset temperature interval as a first interval is to assign the value amplitude 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 a second interval is to assign the value amplitude of the preset second interval to the preset time interval or the preset temperature interval. Therefore, these steps actually configure one of the preset first interval and second interval values ​​to the preset time interval or the preset temperature interval.

[0062] More specifically, in actual use, the heating power of the high-power mode may change due to the environment, power supply environment, equipment loss, etc., and is generally lower than the rated thermal power preset at the factory; and in the heating process of the water dispenser, the size of the heating power will affect the speed of change of the water hardness. When the water dispenser is in a high-power heating state, the water temperature rises rapidly, the precipitation rate of minerals in the water is accelerated, scale is easily generated quickly, and the water hardness changes relatively quickly. Relatively speaking, when the water dispenser is in a low-power heating state, the water temperature rises slowly, and the water hardness changes relatively slowly; therefore, in order to obtain water hardness data more efficiently and accurately, the above steps dynamically adjust the acquisition interval of the water hardness data according to the size relationship between the current heating power and the preset power threshold; wherein the preset power threshold is a pre-set reference value, which can be the rated thermal power preset at the factory for the high-power mode, or it can be slightly less than the rated power, such as set to 90% of the rated power, preferably the latter; the specific implementation process of the above adjustment process: obtaining the water hardness data The current heating power of the water dispenser, and then, determine whether the current heating power is greater than the preset power threshold, so as to determine whether the heating power of 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 a high-power heating state. At this time, a shorter first interval is set as the interval for obtaining the water hardness data again, so as to obtain the water hardness data relatively frequently and reflect the changes in water hardness in time; conversely, if the current heating power is not greater than the preset power threshold, it indicates that the heating power of the high-power mode of the water dispenser is in an under-power state. At this time, a longer second interval is set as the interval for obtaining the water hardness data again, so as to reduce the frequency of obtaining water hardness data and reduce system resource consumption; therefore, the boiling point adaptive heating control method of the water dispenser in the embodiment of the present application can dynamically adjust the frequency of obtaining water hardness data according to the actual use of the high-power mode, and improve data acquisition efficiency, optimize system performance, and reduce unnecessary system resource occupation while ensuring the timeliness of updating the water hardness data.

[0063] More specifically, the specific type of 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, the temperature interval can be selected; in a scenario where high time response requirements are required, the time interval can be selected.

[0064] In some preferred embodiments, step S2216 includes: Determining 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; If the temperature 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.

[0065] Specifically, the above steps introduce a preset threshold as a selection basis 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 hardness has changed significantly, and step S2216 will use the updated first temperature threshold adjustment amount to adjust the first temperature threshold; conversely, if the absolute value of the difference does not exceed the preset threshold, it indicates that the water hardness has not changed much. In order to ensure the stability of heating control, the water dispenser boiling point adaptive heating control method of the embodiment of the present application will maintain the use of the initial first temperature threshold adjustment amount to adjust the first temperature threshold; through this processing method, the water dispenser boiling point adaptive heating control method of the embodiment of the present application can effectively avoid frequent adjustments to the temperature threshold due to slight fluctuations in water hardness data, thereby improving the stability of heating control.

[0066] In some preferred embodiments, in step S22, the first temperature threshold before adjustment is determined based on the following method: The first temperature threshold is determined based on the water hardness data, boiling point temperature and a preset temperature mapping relationship. The temperature mapping relationship is a mapping relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water hardness data, wherein the water hardness is positively correlated with the temperature difference between the boiling point temperature and the first temperature threshold.

[0067] Specifically, the temperature mapping relationship describes the changing relationship between the temperature difference between the boiling point temperature and the first temperature threshold and the water hardness data; because when the water dispenser is in a high-power heating state, the water temperature rises rapidly, the mineral precipitation speed in the water is accelerated, scale is easily generated quickly, and the water hardness changes relatively quickly, and the mineral precipitation speed is faster when it is closer to the boiling point temperature, and the water hardness data is easier 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 hardness, that is, the higher the water hardness data, the greater the temperature difference between the boiling point temperature and the first temperature threshold. Conversely, the lower the water hardness data, the smaller the temperature difference between the boiling point temperature and the first temperature threshold. Therefore, for water with higher water hardness, the first temperature threshold will be set lower than the boiling point temperature, so that the water dispenser can switch to low-power mode earlier when the water hardness is high.

[0068] More specifically, the water dispenser can adaptively set the original first temperature threshold value that is not compensated and adjusted based on step S2216 according to the water hardness, which can accurately obtain a reliable first temperature threshold value in combination with step S2216.

[0069] More specifically, in the embodiment of the present application, since the first temperature threshold is set according to the dynamics of water hardness and boiling point temperature, for water with higher water hardness, the first temperature threshold will be set to a temperature that is more different from the boiling point temperature, so that the water dispenser can switch to low power mode earlier, thereby effectively reducing scale formation while ensuring heating efficiency.

[0070] In some preferred embodiments, the temperature mapping relationship is: T diff = c * ln(WH + d) + e (2) Where, ln is the natural logarithm, c is the coefficient of the logarithmic term, which indicates the degree of influence of the logarithmic term on the temperature difference, c>0; d is the water hardness offset, which is used to adjust the starting point of the logarithmic function, d≥0; e is the temperature difference reference offset, which indicates the temperature difference reference when the water hardness is zero, e≥0, T diff is the temperature difference between the boiling point and the first temperature threshold, WH is the water hardness data, c, d and e are all preset parameters; The process of determining the first temperature threshold according to the water hardness data, the boiling point temperature and the preset temperature mapping relationship includes: Calculate and obtain the temperature difference based on the water hardness data and temperature mapping relationship; The first temperature threshold is obtained by calculating the temperature difference and the boiling point based on the following formula: T1 = T boil -T diff , Tboil is the boiling point temperature, and T1 is the first temperature threshold.

[0071] Specifically, the natural logarithm ln in the formula is used to construct the water hardness data WH and the temperature difference T diff Parameter c is the coefficient of the logarithmic term, which is used to adjust the influence of the logarithmic term on the temperature difference. Parameter d is the water hardness offset, which is used to adjust the starting point of the logarithmic function. Parameter e is the temperature difference reference offset, which represents the temperature difference reference when the water hardness is zero. These preset parameters c, d and e allow the temperature mapping relationship curve to be flexibly adjusted according to the actual application scenario to meet the needs of different water qualities and water dispenser designs.

[0072] More specifically, the boiling point adaptive heating control method for the water dispenser of the embodiment of the present application constructs a temperature mapping relationship by adopting a logarithmic function, and combines the set parameters c, d and e to achieve an accurate description of the influence of water hardness on the first temperature threshold. It can more accurately describe the influence of water hardness data on the first temperature threshold, thereby more accurately determining the first temperature threshold, thereby 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 scale.

[0073] In some preferred embodiments, the water dispenser boiling point adaptive heating control method further includes the following steps performed after step S3: S4. Control the heating device to maintain heating in a low power mode, so that the drinking water boils at a boiling point temperature for a preset time, wherein the preset time increases as the boiling point temperature decreases.

[0074] Specifically, for the continuous boiling step, the boiling point adaptive heating control method for the water dispenser of the embodiment of the present application is performed in a low-power mode, with the purpose of reducing energy consumption and reducing the generation of scale while maintaining the boiling state, wherein the preset duration is set to be associated with the boiling point temperature, which is mainly manifested in that when the boiling point temperature decreases, the preset duration increases; this setting takes into account that at a lower boiling point temperature, the boiling degree of water is weakened, so a longer boiling time is required to ensure that the drinking water is fully processed. 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 drinking water, but also avoids energy waste caused by unnecessary long-term heating.

[0075] In some implementations, the preset duration is determined by looking up a preset boiling duration adjustment table, in which a plurality of boiling point temperature values ​​and a preset boiling duration corresponding to each boiling point temperature value are recorded.

[0076] In some preferred embodiments, step S4 comprises: S41, calculating the preset duration required for boiling according to an exponential function model, wherein the exponential function model is: T duration =f⋅exp(g⋅(T boil_ref −T boil ))+T base (3) Where f is the proportionality coefficient, f>0, g is the exponential coefficient, g>0, T base is the basic boiling time, T base >0,T boil_ref is the reference boiling point temperature, T duration is the preset duration, exp is the exponential function; S42: Based on a preset duration, control the heating device to maintain heating in a low power mode when the drinking water is in a boiling state.

[0077] Specifically, in step S41, the proportional coefficient f, the exponential coefficient g, the basic boiling time T base and reference boiling point temperature T boil_ref are all pre-set parameters; the proportional coefficient f is used to adjust the amplitude of the exponential function, and the exponential coefficient g is used to control the rate at which the boiling time changes with the boiling point temperature. Basic boiling time T base Ensures a minimum boiling time even at higher boiling temperatures. Reference boiling 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 time increases nonlinearly as the boiling temperature decreases, which more accurately matches 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 boiling effect.

[0078] More specifically, in this embodiment, a low power mode is adopted to avoid overheating and energy waste while maintaining a boiling state, and the heating time for maintaining boiling is determined by T duration This ensures that drinking water can be fully boiled for the preset time at different boiling point temperatures. In this way, the water dispenser can accurately control the boiling time according to the actual boiling point temperature, which not only ensures the safety of drinking water, but also avoids unnecessary energy consumption.

[0079] Second, please refer to Figure 3 and Figure 4 Some embodiments of the present application also provide a water dispenser boiling point adaptive heating control device, which is applied to a water dispenser having an air pressure detection component for collecting ambient air pressure values, and the device includes: The boiling point determination module 201 is used to determine the boiling point temperature of drinking water according to the ambient air pressure value; The first heating module 202 is used to 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; The second heating module 203 is used to control the heating device to continue heating the drinking water in a low power mode after the temperature of the drinking water reaches the first temperature threshold, until the temperature of the drinking water reaches the boiling point.

[0080] The boiling point adaptive heating control device for a water dispenser in an 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, thereby overcoming the defect of the fixed boiling point temperature of a traditional water dispenser and ensuring the accuracy of the boiling point temperature under different air pressure environments. In terms of heating process control, the boiling point adaptive heating control device for a water dispenser in an embodiment of the present application adopts a two-stage heating strategy: first, the drinking water is quickly heated to a preset first temperature threshold in a high-power mode to achieve rapid temperature rise, and after reaching the first temperature threshold, it is switched to a low-power mode to continue heating to the boiling point temperature. This two-stage heating control method reduces energy consumption while ensuring heating efficiency, and reduces scale generated by violent boiling, thereby achieving more accurate, efficient, and healthier heating control of a water dispenser.

[0081] In some preferred embodiments, the device further comprises: The boiling maintenance module 204 is used to 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 time, wherein the preset time increases as the boiling point temperature decreases.

[0084] The water dispenser of the embodiment of the present application can automatically adapt to the boiling point to heat drinking water, overcoming the defect of the fixed boiling point temperature of the traditional water dispenser, ensuring the accuracy of the boiling point temperature under different air pressure environments, and at the same time heating through a two-stage heating control method, achieving more accurate, more efficient and healthier water dispenser heating control.
