Description

Technical Field

[0001] The present disclosure relates to the technical field of water purifiers, and in particular to a control method, system, device, medium, and program product for a water purifier. Background Art

[0002] The ambient temperature in different seasons will cause the water inlet temperature of the water purifier to vary. When dealing with different water inlet temperatures, its filtration effect will be affected. However, the existing water purifiers do not consider the impact of water inlet temperature on filtration effect in the water purification control.

[0003] When the inlet water temperature is low, the water purifier's efficiency in filtering impurities decreases. When the inlet water temperature is too high, it affects the activated carbon's adsorption capacity, also adversely affecting the filtration effect. Unstable filtration results can also lead to a mismatch in the sterilization power of the filtered water, resulting in unstable water quality under different environments, excessive wear and tear on the water purifier's filter elements, and shortening the water purifier's service life.

[0042] The present disclosure is further illustrated below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0043] In the embodiments of the present disclosure, prefixes such as "first" and "second" are used only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. In the embodiments of the present disclosure, the use of prefixes such as ordinal numbers to distinguish description objects does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitations should be constituted due to the use of such prefixes. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0044] Example 1

[0045] This embodiment provides a method for controlling a water purifier. Figure 1 As shown, the water purifier includes a sterilization unit and a filtration unit, and the control method includes:

[0046] S101, obtaining water inlet temperature and reference temperature;

[0047] S102, obtaining a sterilization power of the sterilization unit based on the inlet water temperature and the reference temperature;

[0048] S103 , sterilizing the purified water filtered by the filtration unit based on the sterilization power.

[0049] In step S101, a water inlet temperature sensor is provided at the water inlet of the water purifier, and the water inlet temperature is obtained based on the water inlet temperature sensor, and the water inlet temperature is obtained periodically to ensure the timeliness of the water inlet temperature; the reference temperature can be based on the preset reference temperature corresponding to the receiving address of the water purifier, or can be based on the preset reference temperature selected by the user to match the installation address of the water purifier.

[0050] In step S102, the reference temperature reflects the water quality of the water source in the area where the water purifier is located. Higher water temperatures typically accelerate bacterial growth and metabolism, causing them to multiply more rapidly. For tap water, residual chlorine, which has a bactericidal effect, decomposes rapidly at high temperatures, reducing its bactericidal capacity and increasing the bacterial content in the water. Combining the real-time inlet water temperature with the corresponding reference temperature yields a sterilization solution tailored to the water source.

[0051] In step S103, based on the sterilization power obtained from the water inlet temperature and the reference temperature, the water purifier can achieve refined sterilization of the purified water, thereby improving the sterilization efficiency of the water purifier and ensuring the stability of the water quality of the water purifier.

[0052] In this solution, the sterilization power of the water purifier for filtered water is adjusted in real time through the water inlet temperature and reference temperature of the water purifier, so as to achieve timely response to changes in the water inlet temperature, ensure the water quality of the water purifier, and improve the user experience.

[0053] As a feasible way, Figure 2 As shown, step S101 includes:

[0054] S1011, obtaining the location information of the water purifier;

[0055] S1012. Acquire the water temperature of the corresponding water supply site based on the location information;

[0056] S1013: Determine the reference temperature according to the water temperature of the water supply site.

[0057] In this solution, the location information of the water purifier can be based on the user information bound to the water purifier, and the location information of the user can be used as the location information of the water purifier; or, the order information of the water purifier can be obtained, and the delivery address or installation address in the order information can be used as the location information of the water purifier; or, the location information of the water purifier can be obtained based on the positioning service integrated in the Internet of Things to which the water purifier is connected; or, a positioning unit can be integrated into the water purifier to obtain the location information of the water purifier. According to the location information of the water purifier, the relevant hydrological data of the water supply site can be obtained through the location information of the water purifier, and the water temperature of the corresponding water supply site can be determined by the hydrological data, and the matching reference temperature can be obtained by the water temperature of the water supply site. The water purifier can automatically sterilize the water according to the different water temperatures in different places, ensure the water quality of the water outlet, and improve the user experience.

[0058] As an implementable manner, step S1012 includes:

[0059] Acquire water temperatures of at least two reference water supply locations closest to the location information based on the location information;

[0060] The water temperature of the water supply site is calculated based on the water temperature of the reference water supply site.

[0061] In this solution, a water supply typically has multiple hydrometric measurement points at different locations, corresponding to multiple water temperatures. Using the water purifier's location as the origin, several reference water temperatures within a preset radius can be obtained. Alternatively, water temperature data from at least two hydrometric measurement points closest to the water purifier's location, corresponding to the same period or season, can be obtained as reference water temperatures. The average, median, or weighted average of the water temperatures of at least two of these reference water temperatures is used as the water purifier's water temperature. This allows the water purifier to automatically adjust its sterilization power based on the water temperature at different times and seasons, ensuring water quality and improving the user experience.

[0062] As an implementable manner, the step of calculating the sterilization power of the sterilization unit based on the inlet water temperature and the reference temperature includes:

[0063] determining a calculation coefficient based on the reference temperature;

[0064] The difference between the water inlet temperature and the preset temperature is calculated based on the calculation coefficient to obtain the sterilization power of the sterilization unit.

[0065] In this solution, the sterilization unit of the water purifier is an ultraviolet sterilization lamp. The water purifier is controlled by a PID (Proportion-Integration-Differentiation) controller based on a control algorithm. The control algorithm is as follows:

[0066] U(t)=K p e(t)+K i ∑e(t)+K d (e(t)-e(t-1));

[0067] Among them, U(t) is the intensity of the ultraviolet germicidal lamp, K p , K i and K d It is a setting coefficient obtained based on the water temperature of the water supply site, e(t) is the current inlet water temperature obtained by the inlet water temperature sensor, and e(t-1) is the inlet water temperature obtained by the inlet water temperature sensor in the previous cycle.

[0068] The real-time working power of the ultraviolet germicidal lamp is adjusted based on the intensity of the ultraviolet germicidal lamp output by the PID controller. By accurately adjusting the sterilization power, the sterilization efficiency is ensured under different water quality conditions.

[0069] As an achievable manner, the water purifier further includes a booster pump, characterized in that the control method further includes:

[0070] obtaining a target speed of the boost pump based on the water inlet temperature and the reference temperature;

[0071] The booster pump adjusts the pumping pressure based on the target rotation speed, and pumps water to the filter unit for filtration at the pumping pressure.

[0072] In this program, if Figure 3As shown, the filtration unit of the water purifier includes a pre-composite filter element and a post-composite filter element. A booster pump is positioned between the pre-composite filter element and the post-composite filter element. A sterilizing lamp and a flowmeter are positioned after the filtration unit. The booster pump utilizes an adjustable variable speed booster pump, and the post-composite filter element includes a reverse osmosis membrane. Because changes in inlet water temperature affect the filtration efficiency of the filtration unit, and as water temperature rises, calcium and magnesium ions in the water are more likely to form scale, negatively impacting the filtration performance and service life of the filtration unit, a PID controller algorithm adjusts the target speed of the booster pump in real time based on the inlet water temperature and a reference temperature. This precisely regulates the water pressure and flow rate of the filtration unit, ensuring filtration efficiency under varying water temperature conditions, guaranteeing the performance temperature of the filtration unit, and extending the service life of the filtration unit.

[0073] As an achievable manner, the control method further includes:

[0074] Obtaining a corresponding sterilization flow threshold based on the sterilization power;

[0075] obtaining a flow rate of purified water after filtration by the filtration unit based on the target rotation speed;

[0076] In response to the clean water flow being higher than the sterilization flow threshold, the sterilization power is adjusted based on the clean water flow so that the sterilization flow threshold matches the clean water flow.

[0077] In this solution, the water purifier adjusts the booster pump speed and the sterilization power of the sterilization unit in real time based on the inlet water temperature, which may cause the filtered clean water flow rate to be mismatched with the sterilization power. To avoid excessive filtered clean water flow rate, the theoretical flow rate of the booster pump is obtained based on the booster pump speed and the characteristic curve of the booster pump. The resistance of the filter unit to the water flow is obtained based on the performance parameters of the filter unit, and the corresponding theoretical flow correction parameters are obtained. The filtered clean water flow rate is obtained based on the theoretical flow rate of the booster pump and the theoretical flow correction parameters; alternatively, the outlet flow rate obtained by the flow meter installed after the sterilization unit is used as the filtered clean water flow rate. By comparing the calculated filtered clean water flow rate with the corresponding sterilization flow rate of the sterilization unit, the sterilization power of the sterilization unit is adjusted in real time to ensure the stability of the water quality of the water purifier.

[0078] As a feasible method, when the clean water flow rate is higher than the sterilization flow rate threshold, the speed of the booster pump can be appropriately reduced to match the filtered clean water flow rate with the sterilization flow rate threshold, especially when the sterilization power of the sterilization unit reaches or approaches the maximum operating power.

[0079] The control method of the water purifier provided in this embodiment adjusts the sterilization power of the water purifier for filtered water in real time through the water inlet temperature and reference temperature of the water purifier, so as to achieve timely response to changes in the water inlet temperature, ensure the water quality of the water purifier, and improve the user experience.
