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

[0043] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure 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 limitation should be constituted due to the use of such prefixes. In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0044] Example 1

[0045] This embodiment provides a control method for a water purifier, such as 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 water inlet temperature and the reference temperature;

[0048] S103, sterilizing the purified water filtered by the filtering 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. 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 is used to reflect the water quality of the water source in the area where the water purifier is located. The increase in water source temperature usually accelerates the growth and metabolism rate of bacteria, making the bacteria reproduce faster. When tap water is used as the water source, tap water often contains residual chlorine, which has a bactericidal effect, but it will decompose quickly at high temperatures, resulting in a decrease in bactericidal ability and an increase in the bacterial content of tap water. Combined with the real-time inlet water temperature and the corresponding reference temperature, a sterilization solution that matches the water source is obtained.

[0051] In step S103, based on the sterilization power obtained from the water inlet temperature and the reference temperature, the water purifier can sterilize the purified water in a refined manner, thereby improving the sterilization efficiency of the water purifier and ensuring the stability of the water quality of the water purifier's outlet water.

[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 approach, Figure 2 As shown, step S101 includes:

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

[0055] S1012, acquiring 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 is integrated in 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 corresponding water temperature of the 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 output water, and improve the user experience.

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

[0059] Based on the location information, obtain water temperatures of at least two reference water supply locations closest to 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, the water supply site usually has multiple hydrological measurement points at different locations, and corresponding to multiple water temperatures at the water supply site, the water temperatures of several reference water supply sites within a preset radius can be obtained based on the location information of the water purifier as the origin; or, at least two hydrological measurement points closest to the location information of the water purifier are obtained, and the water temperature data corresponding to the same period or season are obtained as the reference water supply site water temperature. The average, median or weighted average of the water temperatures of at least two reference water supplies is used as the water temperature of the water supply site of the water purifier. The water purifier can automatically sterilize the water according to the different water temperatures in different periods and seasons in different places, ensure the water quality of the output water, and improve the user experience.

[0062] As an achievable 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, and 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 UV germicidal lamp is adjusted based on the intensity of the UV germicidal lamp output by the PID controller. The sterilization efficiency under different water quality conditions is ensured by accurately adjusting the sterilization power.

[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 a pumping pressure based on the target rotation speed, and pumps water to the filter unit for filtering at the pumping pressure.

[0072] In this scheme, if Figure 3As shown, the filter unit of the water purifier includes a front composite filter element and a rear composite filter element, the booster pump is arranged between the front composite filter element and the rear composite filter element, and a sterilization lamp and a flow meter are arranged after the filter unit, wherein the booster pump adopts an adjustable variable speed booster pump, and the rear composite filter element includes a reverse osmosis membrane. Since the change of the inlet water temperature will affect the filtration efficiency of the filter unit, and as the water temperature increases, the calcium and magnesium ions in the water are more likely to form scale, which has a negative impact on the filtration performance and service life of the filter unit, the algorithm of the PID controller is used to adjust the target speed of the booster pump in real time according to the inlet water temperature and the reference temperature, so as to accurately adjust the water pressure and flow of the filter unit, ensure the filtration efficiency under different water temperature conditions, guarantee the performance temperature of the filter unit, and improve the service life of the filter 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 clean water flow rate 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 speed of the booster pump 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 speed of the booster pump and the characteristic curve of the booster pump, and the resistance of the filter unit to the water flow is obtained according to 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; or, the water outlet flow rate obtained by the flowmeter set 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 boost pump can also 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.
