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

[0027] In daily life, the treatment and heating of drinking water is an unavoidable part. With the development of technology and people's pursuit of a healthy and convenient life, water purifiers, as devices that integrate water purification, heating, and cooling functions, are gradually gaining popularity in the market. Among them, the boiled water purifier with cooled boiled water, due to its special purification process and instant hot and cold water function, better meets the requirements of modern people for a healthy life and has become a star product in the water purifier market.

[0028] Traditional water purifiers only purify water. To get the desired temperature of cooled boiled water, users still need to go through multiple steps: filling the container, boiling the water, and letting it cool. This is not only inconvenient but also time-consuming and laborious. Furthermore, even in water purifiers with temperature control, the traditional method of adjusting the temperature by mixing boiling and cold water under user control of a valve lacks precision and requires manual valve adjustment. Therefore, the accuracy of the water temperature from traditional water purifiers depends on user operation, resulting in low accuracy and automation, and failing to meet users' specific temperature requirements for cooled boiled water.

[0029] This specification provides a method for adjusting the outlet water temperature of a boil-water purifier. It should be noted that the executing entity in this specification can be a server or any device with data processing capabilities. Figure 1 This is a flowchart illustrating a method for adjusting the outlet water temperature of a boil-and-cool water purifier, as provided in the embodiments of this specification. Figure 1 As shown, the main steps include the following:

[0030] Step S101: Obtain the target outlet water temperature and the actual inlet water temperature set by the user, and determine the heat exchange performance parameters of the boiled water purifier.

[0031] In one embodiment of this specification, the user sets a target water temperature on the control panel of the boiled water purifier. This target water temperature is the desired temperature of the boiled water the user wants to drink. The user-set target water temperature is obtained through a trigger operation on the control panel. Additionally, the boiled water purifier is connected to a water supply source and is equipped with a temperature sensor to collect the actual inlet water temperature.

[0032] Figure 2 This is a schematic diagram of the water circuit structure of a boil-water purifier provided in the embodiments of this specification, as shown below. Figure 2 As shown, the boiled water purifier includes a water supply module. A water pump draws water from the water supply module, and a temperature sensor 1, located between the water supply module and the water pump, reads the actual inlet water temperature. After passing through the water pump, the water enters the first water path of the heat exchange module, and then enters the instant heating element, where it is heated to boiling water. When the proportional control valve's valve opening angle is adjusted to 0 degrees, the proportional control valve only opens inlet 1. At this time, the heated boiling water passes through the proportional control valve and exits from the outlet. When the proportional control valve's valve opening angle is adjusted to the maximum angle (let's call it A), the proportional control valve only opens inlet 2. Since inlet 1 is closed, the boiling water flows to the second water path of the heat exchange module. The boiling water in the second water path of the heat exchange module exchanges temperature with the room temperature water in the first water path of the heat exchange module. After the boiling water temperature decreases, it flows out of the heat exchange module, flows to inlet 2, and passes through the proportional control valve before exiting from the outlet. When the opening angle of the proportional control valve is adjusted to a certain intermediate angle (denoted as 'a'), the proportional control valve opens inlet 1 and inlet 2 according to a certain ratio. Part of the boiling water flows to inlet 1, and the other part flows to the second water path of the heat exchange module. After cooling down in the second water path, it flows back to inlet 2 of the proportional control valve. At this point, the boiling water and the cooled boiling water mix and adjust their temperature within the proportional control valve before flowing out from the outlet. It should be noted that the first water path can also be called the cold water path or the normal temperature water path, and the second water path can also be called the boiling water path. The pipe corresponding to the second water path is located inside the pipe corresponding to the first water path; that is, the second water path is enclosed by the first water path. By making the water flow directions in the first and second water paths opposite—that is, during the heat exchange process, the cold water in the cold water path and the hot water in the hot water pipe flow in opposite directions—compared to the co-current flow heat exchange method, the opposite flow allows for more complete heat exchange between the hot and cold water, resulting in higher heat exchange efficiency and faster cooling of the hot water.

[0033] In practical applications, different boiled water purifiers have varying heat exchange performance due to limitations imposed by their proportional control valves. Before controlling the outlet water temperature, it is necessary to determine the heat exchange parameters of the current boiled water purifier.

[0034] In one embodiment of this specification, determining the heat exchange performance parameters of a boil-water purifier specifically includes the following steps:

[0035] First, obtain the valve adjustment range of the proportional control valve. This range can be obtained from the inherent parameters of the proportional control valve. Then, based on the valve adjustment range, determine the maximum opening angle of the proportional control valve. It should be noted that when the proportional control valve is at its maximum opening angle, the boiling water in the second water circuit of the heat exchange module and the room temperature water in the first water circuit of the heat exchange module exchange temperatures. Therefore, the maximum opening angle represents the heat exchange performance of the heat exchange module.

[0036] The opening angle of the proportional control valve is controlled to its maximum, and the corresponding outlet water temperature is collected. Based on this outlet water temperature and the pre-acquired current inlet water temperature, the heat exchange performance parameter is generated. Specifically, the valve plate opening angle is adjusted to its maximum, allowing all boiling water to pass through the heat exchange module for cooling before exiting the outlet. The cooled water temperature (outlet temperature) is compared with the inlet water temperature to determine the difference, which is then used as the heat exchange performance parameter of the boiled water purifier. This technical solution considers the differences in heat exchange performance caused by different proportional control valves in different boiled water purifiers, ensuring the accuracy and specificity of the heat exchange performance parameters.

[0037] Step S102: Determine the adjustment index of the water output ratio regulating valve of the boiled water purifier by using the target outlet water temperature, the actual inlet water temperature, and the cold and heat exchange performance parameters.

[0038] In one embodiment of this specification, the adjustment index of the water output ratio regulating valve of the boiled water purifier is determined by the target outlet water temperature, the actual inlet water temperature, and the heat exchange performance parameters. The adjustment index of the water output ratio regulating valve here includes the valve plate opening angle or the valve plate opening ratio of the water output ratio regulating valve. The valve plate opening ratio is the proportion of the current valve plate opening angle to the maximum opening angle.

[0039] The adjustment parameters of the water output ratio regulating valve of the boiled water purifier are determined by using the target outlet water temperature, the actual inlet water temperature, and the heat exchange performance parameters. The specific steps include:

[0040] First, based on the target outlet water temperature T2 and the pre-obtained actual boiling point temperature T, the first required temperature value for heat exchange of the boiled water purifier is determined, i.e., T2-T. Then, using the actual inlet water temperature T0 and the heat exchange performance parameter ΔT, the actual exchange temperature value T1 after heat exchange of the boiled water purifier is determined, i.e., T1 = ΔT + T0. Finally, using the actual exchange temperature value T1 and the actual boiling point temperature T, the second required temperature value for heat exchange of the boiled water purifier is determined, i.e., T1-T.

[0041] Finally, based on the first and second required temperatures for heat exchange (T2-T) and heat exchange (T1-T), the adjustment index of the proportional control valve corresponding to the target outlet water temperature is determined. The calculation method for the adjustment index varies depending on the specific adjustment index.

[0042] When the adjustment index is the valve plate opening angle, based on the pre-acquired maximum opening angle A of the outlet proportional control valve and the second required temperature value for heat exchange (T1-T), the opening angle corresponding to a unit temperature value is determined, that is, the ratio of the maximum opening angle A to the second required temperature value for heat exchange (T1-T); using the opening angle corresponding to the unit temperature value and the first required temperature value for heat exchange (T2-T), the valve plate opening angle α of the outlet proportional control valve is determined, and the calculation formula is as follows:

[0043]

[0044] Where a is the valve plate opening angle, A is the maximum opening angle of the proportional control valve, T2 is the target outlet water temperature, T is the actual boiling point temperature, T1 is the actual exchange temperature value, and T2 is the sum of the actual inlet water temperature T0 and the heat exchange performance parameter ΔT. Figure 3 This is a schematic diagram illustrating the relationship between the valve plate opening angle and the outlet water temperature of a proportional regulating valve provided in an embodiment of this specification. Figure 3 As shown, when the valve plate of the proportional control valve is open at 0 degrees, the corresponding outlet water temperature is the boiling water temperature. As the valve plate of the proportional control valve increases, the outlet water temperature gradually decreases. When the valve plate of the proportional control valve is at its maximum opening angle, the outlet water temperature is the actual inlet water temperature.

[0045] When the adjustment index is the valve opening / closing ratio, the valve opening / closing ratio β of the proportional control valve corresponding to the target outlet water temperature is determined based on the ratio of the first and second required temperatures for heat exchange. The calculation formula is as follows:

[0046]

[0047] Where β is the valve opening / closing angle. Figure 4This is a schematic diagram illustrating the relationship between the valve plate opening angle and the outlet water temperature of a proportional regulating valve provided in an embodiment of this specification. Figure 4 As shown, when the valve plate of the outlet proportional control valve is open at 0 degrees, the corresponding outlet water temperature is the boiling water temperature. As the valve plate of the outlet proportional control valve increases, the outlet water temperature gradually decreases. When the valve plate of the outlet proportional control valve is open at 1 degree, the outlet water temperature is the actual inlet water temperature.

[0048] By quantifying the relationship between the adjustment index of the proportional control valve and the outlet water temperature through the above technical solution, the adjustment index corresponding to the target outlet water temperature can be accurately obtained, thereby achieving precise control of the outlet water temperature and ensuring the accuracy and precision of water temperature control.

[0049] Furthermore, in practical applications, boiling point temperatures differ at different altitudes and atmospheric pressures. Therefore, the actual boiling point temperature can be obtained through self-learning. Before determining the adjustment parameters of the water output ratio regulating valve of the boiled water purifier using the target outlet water temperature, the actual inlet water temperature, and the heat exchange performance parameters, the method includes: triggering a user's power-on operation, performing boiling point temperature self-learning according to a preset self-learning timing indicator to determine the actual boiling point temperature corresponding to the current environment. That is, when the user needs to use the boiled water purifier, they turn on the switch to power on the device. Triggered by the user's power-on operation, the boiling point temperature is self-learned in the current environment according to the preset self-learning timing indicator to determine the actual boiling point temperature. Here, the self-learning timing indicator is the boiling point temperature recording time during the self-learning process.

[0050] The heating parameters of the boiled water purifier are obtained, and the heat output per unit time of the boiled water purifier is calculated based on the heating parameters, wherein the heating parameters include the heating element power and heating element efficiency; the heat required for temperature rise is determined according to the specified boiling point temperature and the actual inlet water temperature; the heating time required to heat to the specified boiling point temperature is determined according to the heat required for temperature rise and the heat output per unit time, and the self-learning timing index is determined by the heating time.

[0051] Specifically, the self-learning timing index can be determined using the following formula:

[0052]

[0053] Where t is the heating time required to reach the specified boiling point temperature, c is the specific heat capacity of water, m is the water flow rate per second, and T xTo specify the boiling point temperature, the highest boiling point temperature of 100℃ can be taken. T0 is the actual inlet water temperature, η is the efficiency of the heating element in the instant heating element of the water purifier, and P is the heating element efficiency. The time calculated according to the above formula is the heating time required to heat to the highest boiling point temperature. Since the boiling point temperature decreases with increasing altitude, the obtained heating time is the maximum heating time. That is, heating according to the maximum heating time can theoretically reach the boiling point temperature at various altitudes. To ensure the accuracy of boiling point temperature learning, a correction time can be added to the maximum heating time to obtain a self-learning timing index. The correction time here can be determined based on user experience, for example, set to ten seconds, to ensure that the boiling point temperature can be reached at various altitudes under the time corresponding to the self-learning timing index.

[0054] According to the self-learning timing index, boiling point temperature is learned. During the self-learning process, the boiling point temperature recording time is the time after which the actual water temperature is continuously monitored. When the actual water temperature no longer changes, the fixed temperature value is taken as the actual boiling point temperature, thus completing the boiling point temperature self-learning. By learning the boiling point temperature of water through the program, the usage needs of water purifiers at different altitudes and atmospheric pressures can be met, expanding the application scenarios of the boiled water purifier.

[0055] Step S103: According to the adjustment index of the water output ratio regulating valve, the actual water output temperature of the boiled water purifier is controlled by controlling the water output ratio regulating valve to achieve water output temperature adjustment.

[0056] In one embodiment of this specification, when a user takes water, the system calculates the theoretical adjustment index of the proportional control valve based on the user-set water temperature, and automatically adjusts the adjustment index of the proportional control valve to quickly bring the water temperature close to the user-set water temperature.

[0057] In actual use, due to the power consumption of the water purifier, the water temperature may be inaccurate after dispensing. In this case, a temperature sensor at the water outlet monitors the actual water temperature in real time. The temperature deviation between the actual and target water temperatures is compared, and the adjustment parameters of the proportional control valve are adjusted to determine the specified adjustment parameters. Based on these parameters, the actual water temperature is adjusted to ensure that the absolute value of the temperature deviation does not exceed a preset temperature difference threshold, thus achieving the user-set water temperature.

[0058] In the above process, the adjustment index of the outlet water proportional control valve is adjusted based on the actual outlet water temperature to determine the adjusted specified adjustment index. This specifically includes the following steps:

[0059] The following explanation uses the valve opening angle of a proportional control valve as an example. Using the actual inlet water temperature T0 and the heat exchange performance parameter ΔT, the actual heat exchange temperature after the water purifier is determined, i.e., T1 = ΔT + T0. Based on the actual heat exchange temperature T1, the pre-obtained actual boiling point temperature T, and the pre-obtained maximum opening angle A of the proportional control valve, the unit adjustable temperature corresponding to the unit adjustment index of the proportional control valve is determined, i.e., the adjustable unit temperature corresponding to each degree of opening / closing. Based on the ratio of the temperature deviation value to the unit adjustable temperature, the adjusted specified adjustment index is determined. This specified adjustment index includes the valve adjustment index value and the valve adjustment direction, and the corresponding calculation formula is shown below:

[0060]

[0061] Where Δa is the corresponding fine-tuning angle, T2 is the target outlet water temperature, T3 is the actual outlet water temperature, T is the actual boiling point temperature, T1 is the actual exchange temperature, and A is the maximum opening angle of the proportional control valve. It should be noted that when the opening angle of the proportional control valve is 0 degrees, the corresponding outlet water temperature is the boiling point; when the opening angle is at its maximum, the outlet water temperature is the actual inlet water temperature. Therefore, when the actual outlet water temperature is greater than the target outlet water temperature (T3 > T2), the resulting Δa is negative, and the proportional control valve is adjusted towards the maximum opening angle; when the actual outlet water temperature is less than the target outlet water temperature (T2 > T3), the resulting Δa is positive, and the proportional control valve is adjusted towards 0 degrees. The resulting Δa value is used as the valve adjustment index value. Throughout the water intake process, the control valve continuously fine-tunes its opening angle according to the actual water temperature at the outlet, keeping the outlet water temperature stable. During operation, it can learn and record the preset angle of the regulating valve in real time, and the outlet water temperature can quickly and accurately reach the temperature set by the user.

[0062] The above technical solution first determines the heat exchange performance parameters of the boiled water purifier, taking into account the differences in heat exchange performance caused by different proportional control valves in different boiled water purifiers, ensuring the accuracy and specificity of the heat exchange performance parameters. The relationship between the proportional control valve's adjustment index and the outlet water temperature is quantified, allowing for accurate determination of the adjustment index corresponding to the target outlet water temperature, achieving precise control of the outlet water temperature and ensuring the accuracy and precision of water temperature control. By automatically controlling the outlet proportional control valve, the actual outlet water temperature of the boiled water purifier is controlled, avoiding manual operation by the user, enabling rapid adjustment of the outlet water temperature, and improving the accuracy and precision of the outlet water temperature.

[0063] This specification also provides an embodiment of a device for adjusting the outlet water temperature of a boil-water purifier, such as...

[0064] The system obtains the user-set target outlet water temperature and actual inlet water temperature, and determines the heat exchange performance parameters of the boiled water purifier. Based on the target outlet water temperature, the actual inlet water temperature, and the heat exchange performance parameters, it determines the adjustment index of the water output ratio regulating valve of the boiled water purifier. According to the adjustment index of the water output ratio regulating valve, the system controls the actual outlet water temperature of the boiled water purifier by controlling the water output ratio regulating valve, thereby achieving water temperature regulation.
