[0023] The adaptive method for the output voltage of a water purifier controller provided in the embodiment of the present disclosure may be performed by a water purifier, and the device may be understood as any water purification device that uses a filter membrane to filter water.

[0024] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in conjunction with exemplary embodiments.

[0025] Figure 1 is a flow chart of a method for self-adapting the output voltage of a water purifier controller provided by an embodiment of the present disclosure, such as Figure 1As shown, the self-adaptive method for the output voltage of the water purifier controller provided in this embodiment includes the following steps:

[0026] Step 110: In response to receiving the water purification instruction, the water purifier starts a water purification program and monitors the pressure before the membrane of the filter membrane of the water purifier.

[0027] In the disclosed embodiment, the water purifier is provided with at least a controller, a water pump and a filter membrane. The controller is used to provide voltage to the water pump. The water pump pressurizes the water using the voltage and then transports the water to the filter membrane. The filter membrane filters the water. Therefore, the voltage provided by the controller to the water pump is crucial to the purification effect of the water purifier.

[0028] In the embodiment of the present disclosure, upon receiving the water purification instruction, the water purifier may start the water purification program and monitor the pressure in front of the filter membrane of the water purifier. For example, the pressure in front of the filter membrane may be monitored by a pressure detector disposed between the controller and the filter membrane.

[0029] Step 120, when the pre-membrane pressure is within the normal working pressure range of the filter membrane, obtain the output voltage provided by the target controller in the water purifier to the target water pump under the pre-membrane pressure, as well as the pure water flow and wastewater flow of the water purifier under the output voltage.

[0030] In the embodiment of the present disclosure, when the pre-membrane pressure of the filter membrane is in the normal working pressure range, the water purifier can obtain the output voltage provided to the target water pump by the target controller in the water purifier under the pre-membrane pressure, as well as the pure water flow and wastewater flow of the water purifier under the output voltage.

[0031] For example, the pure water flow rate can be obtained by a flow meter set at the pure water outlet, and the pure water flow rate can be obtained by a flow meter set at the waste water outlet.

[0032] Among them, the normal working pressure range can be understood as the range of pressure in front of the membrane when the filter membrane is working normally, for example, it can be 0.3Mpa-0.5Mpa, 0.6-0.8Mpa, 0.9-1.1Mpa, or 0.3Mpa-1.1Mpa, and the normal working pressure range is determined by the properties of the filter membrane itself; and / or, when the pressure in front of the membrane of the filter membrane is in the normal working pressure range of the filter membrane, the output voltage provided by the corresponding target controller to the target water pump can be 23V-36V.

[0033] Pure water flow can be understood as the flow of clean water after filtering through the filter membrane, and wastewater flow can be understood as the flow of wastewater generated by filtering through the filter membrane.

[0034] In some embodiments, when the pressure in front of the filter membrane is less than the minimum pressure value of the normal working pressure interval of the filter membrane, the water purifier can boost the output voltage provided by the target controller to the target water pump so that the pressure in front of the filter membrane is in the normal working pressure interval. When the pressure in front of the filter membrane is equal to the maximum pressure value of the normal working pressure interval of the filter membrane, the water purifier can stop boosting to avoid damage to the filter membrane due to too high pressure in front of the membrane.

[0035] In other embodiments, when the pre-membrane pressure is greater than the maximum pressure value of the normal working pressure range of the filter membrane, the water purifier can reduce the output voltage provided by the target controller to the target water pump so that the pre-membrane pressure of the filter membrane is in the normal working pressure range. After reducing the output voltage, if the pre-membrane pressure is still greater than the maximum pressure value of the normal working pressure range, it means that there may be a problem with the water purifier components other than the target controller and the target water pump. The water purifier can shut down the water purification program and issue an alarm message that the pre-membrane pressure of the filter membrane is too high.

[0036] Step 130, determine the target output voltage of the target controller according to the pure water flow, the wastewater flow and the output voltage, wherein the ratio of the pure water flow to the wastewater flow is the pure-to-waste ratio, and the target output voltage is the output voltage of the target controller that satisfies both the set flux of the water purifier and the set pure-to-waste ratio.

[0037] In the disclosed embodiment, after obtaining the pure water flow, wastewater flow and output voltage under the output voltage, the water purifier can determine the target output voltage of the target controller based on the pure water flow, wastewater flow and output voltage, wherein the ratio of the pure water flow to the wastewater flow is the pure-waste ratio, and the target output voltage is the output voltage of the target controller that simultaneously satisfies the set flux and the set pure-waste ratio of the water purifier.

[0038] Pure water flow can be understood as the flow of water that reaches the preset cleanliness level after the water purifier filters the raw water; wastewater flow can be understood as the flow of water that does not reach the preset cleanliness level after the water purifier filters the raw water. The larger the pure-to-waste ratio, the more pure water the water purifier produces, the less waste water, and the higher the filtration efficiency of the water purifier; the smaller the pure-to-waste ratio, the less pure water the water purifier produces, the more waste water, and the lower the filtration efficiency of the water purifier.

[0039] The target output voltage can be understood as the output voltage of the target controller that simultaneously satisfies the set flux and the set pure-waste ratio of the water purifier, that is, when the pure water flow rate of the water purifier is greater than or equal to the set flux of the water purifier and the pure-waste ratio of the water purifier is greater than or equal to the set pure-waste ratio of the water purifier, the corresponding target controller provides the output voltage to the target water pump.

[0040] The set flux of the water purifier can be understood as the minimum flux required by the water purifier, and the set pure waste ratio of the water purifier can be understood as the minimum pure waste ratio required by the water purifier. The set flux and the set pure waste ratio can be set as needed and are not specifically limited here.

[0041] In some embodiments, when the pure water flow rate is greater than or equal to the set flux of the water purifier and the pure-waste ratio is greater than or equal to the set pure-waste ratio of the water purifier, it means that the pure water flow rate obtained by the filter membrane filtration and the wastewater flow rate generated at this time both meet the minimum requirements of the water purifier. The water purifier can determine the output voltage provided by the target controller to the target water pump at this time as the target output voltage of the target controller.

[0042] In other embodiments, when the pure water flow rate is less than the set flux of the water purifier or the pure-to-waste ratio is less than the set pure-to-waste ratio of the water purifier, it means that the pure water flow rate obtained by the filter membrane filtration or the wastewater flow rate generated at this time does not meet the minimum requirement of the water purifier. At this time, the water purifier can boost the output voltage provided by the target controller to the target water pump until the pure water flow rate is greater than or equal to the set flux of the water purifier and the pure-to-waste ratio is greater than or equal to the set pure-to-waste ratio of the water purifier, and then stop boosting, and determine the output voltage provided by the target controller to the target water pump when stopping boosting as the target output voltage of the target controller.

[0043] In the disclosed embodiment, in response to receiving a water purification instruction, the water purifier starts a water purification program and monitors the pre-membrane pressure of the filter membrane of the water purifier; when the pre-membrane pressure is in the normal working pressure range of the filter membrane, the output voltage provided to the target water pump by the target controller in the water purifier under the pre-membrane pressure, as well as the pure water flow and wastewater flow of the water purifier under the output voltage are obtained; according to the pure water flow, the wastewater flow and the output voltage, the target output voltage of the target controller is determined, wherein the ratio of the pure water flow to the wastewater flow is the pure-waste ratio, and the target output voltage is the voltage that satisfies both the set flux and the set pure-waste ratio of the water purifier. The output voltage of the corresponding target controller can determine the actual output voltage provided by the controller in the water purifier to the water pump according to the pure water flow, wastewater flow generated by the water purifier and the output voltage provided by the controller to the water pump, and then control the water pressure output by the water pump to the filter membrane to achieve the set flux and set pure-waste ratio of the water purifier. The controller can adapt to the water purification voltage requirements of water purifiers with different fluxes. A controller and water pump of one specification can meet the set flux and set pure-waste ratio of multiple water purifiers with different fluxes, which can reduce the number of specifications of controllers and water pumps required for water purifiers with different fluxes and reduce costs.

[0044] Figure 2 is a flow chart of a method for self-adapting the output voltage of a water purifier controller provided by an embodiment of the present disclosure, such as Figure 2 As shown, the self-adaptive method for the output voltage of the water purifier controller provided in this embodiment includes the following steps:

[0045] Step 201. In response to receiving a water purification instruction, the water purifier starts a water purification program, boosts the output voltage provided by the target controller in the water purifier to the target water pump to a first voltage, and obtains a first relationship curve between the output voltage of the target controller and the pre-membrane pressure of the filter membrane during the boosting process. The first voltage is less than the output voltage of the controller corresponding to a preset minimum flux, and the preset minimum flux is less than the set flux of the water purifier.

[0046] In the embodiment of the present disclosure, the water purifier can start a water purification program in response to receiving a water purification instruction, boost the output voltage provided by the target controller in the water purifier to the target water pump to a first voltage, and obtain a first relationship curve between the output voltage of the target controller and the pre-membrane pressure of the filter membrane during the boosting process.

[0047] The first voltage is smaller than an output voltage of the controller corresponding to a preset minimum flux, and the preset minimum flux is smaller than a set flux of the water purifier.

[0048] Step 202, obtain the second relationship curve between the output voltage of the controller of each other water purifier and the pre-membrane pressure of the filter membrane among N other water purifiers with different set fluxes, and obtain N second relationship curves, where N is a positive integer, and the model of the controller and the model of the water pump in each other water purifier are the same as the model of the target controller and the model of the target water pump in the water purifier.

[0049] In the embodiment of the present disclosure, the water purifier can obtain the second relationship curve between the output voltage of the controller of each other water purifier and the pre-membrane pressure of the filter membrane among N other water purifiers with different set fluxes, and obtain N second relationship curves.

[0050] Wherein, N is a positive integer and can be set as required and is not limited here.

[0051] The other water purifiers are water purifiers with determined controller models and water pump models, and the controller model and water pump model in each of the other water purifiers are the same as the target controller model and target water pump model in the water purifier.

[0052] For example, Figure 3a A schematic diagram of the relationship between the output voltage of the controller of a water purifier with different fluxes and the pressure before the filter membrane is provided, such as Figure 3aAs shown, the horizontal axis is the pressure in front of the filter membrane, the vertical axis is the output voltage of the controller, N is 3, 300 is the first relationship curve between the output voltage of the target controller of the water purifier in the embodiment of the present disclosure and the pressure in front of the filter membrane, 310 is the second relationship curve between the output voltage of the controller of other water purifier 1 and the pressure in front of the filter membrane, 320 is the second relationship curve between the output voltage of the controller of other water purifier 2 and the pressure in front of the filter membrane, 330 is the second relationship curve between the output voltage of the controller of other water purifier 3 and the pressure in front of the filter membrane, the model of the controller and the model of the water pump in each other water purifier are the same as the model of the target controller and the model of the target water pump in the water purifier, and the set flux of each other water purifier is different.

[0053] Step 203: In the second relationship curve, determine the adjacent relationship curves of the first relationship curve, and select the adjacent relationship curve with the lowest slope as the target curve.

[0054] In the embodiment of the present disclosure, among the second relationship curves corresponding to other water purifiers, the water purifier may determine the adjacent relationship curves of the first relationship curve, and select the adjacent relationship curve with the lowest slope as the target curve.

[0055] For example, Figure 3a As shown, in the second relationship curves 310 , 320 and 330 , the adjacent relationship curves of the first relationship curve 300 are 320 and 330 , wherein the adjacent relationship curve with the lowest slope is 330 , and 330 is the target curve.

[0056] In some embodiments, when the number of adjacent relationship curves of the first relationship curve is one, the water purifier may determine the adjacent relationship curve as the target curve.

[0057] In other embodiments, when there are two adjacent relationship curves, the water purifier may select a curve with a smaller slope from the two adjacent relationship curves as the target curve. Figure 3a As shown, there are two adjacent relationship curves 320 and 330, and the curve with a smaller slope is 330, so 330 is used as the target curve.

[0058] Step 204: for the target curve and other second relationship curves with a slope greater than the slope of the target curve, sort the highest output voltages of the controllers corresponding to the curves in order of slope from small to large, and construct a voltage gradient for the boost process.

[0059] In the disclosed embodiment, for the target curve and other second relationship curves whose slopes are greater than the slope of the target curve, the water purifier can sort the highest output voltages of the controllers corresponding to each curve in order of slope from small to large, and construct a voltage gradient for the boost process.

[0060] In some embodiments, the maximum output voltage of the controller corresponding to each curve can be based on Figure 3b The relationship between the controller output voltage and the boost time is shown in the following figure: Figure 3b As shown in the figure, the relationship curves between the output voltage of the controller and the boost time of other water purifiers 1, other water purifiers 2 and other water purifiers 3 are respectively shown. As the boost time increases, the output voltage of the controller reaches the maximum output voltage. The maximum output voltage of the controller in other water purifier 1 is about 36V, the maximum output voltage of the controller in other water purifier 2 is about 30V, and the maximum output voltage of the controller in other water purifier 3 is about 23V.

[0061] Step 205: monitor the pressure before the membrane of the filter membrane of the water purifier.

[0062] In the disclosed embodiment, the water purifier can monitor the pre-membrane pressure of the filter membrane of the water purifier.

[0063] Step 206: When the pressure before the membrane is less than the minimum pressure value of the normal working pressure range of the filter membrane, the output voltage is boosted in the order of voltage from small to large in the voltage gradient so that the pressure before the membrane of the filter membrane is in the normal working pressure range.

[0064] In the embodiment of the present disclosure, after obtaining the voltage gradient of the boosting process, the water purifier can boost the output voltage provided by the target controller in the water purifier to the target water pump in the order of the voltage gradient from small to large, and monitor the pre-membrane pressure of the filter membrane of the water purifier during the boosting process.

[0065] Step 207, when the pre-membrane pressure is within the normal working pressure range of the filter membrane, obtain the output voltage provided by the target controller in the water purifier to the target water pump under the pre-membrane pressure, as well as the pure water flow and wastewater flow of the water purifier under the output voltage.

[0066] In the embodiment of the present disclosure, when the pressure in front of the filter membrane is in the normal working pressure range of the filter membrane, the water purifier can obtain the output voltage provided to the target water pump by the target controller in the water purifier under the pressure in front of the membrane, as well as the pure water flow and wastewater flow of the water purifier under the output voltage.

[0067] In some embodiments, when the pressure in front of the membrane is less than the minimum pressure value of the normal working pressure range of the preset pressure interval, the water purifier can continue to boost the output voltage from small to large according to the voltage gradient until the pressure in front of the membrane of the filter membrane is in the normal working pressure range of the preset pressure interval, and obtain the output voltage of the water purifier under the pressure in front of the membrane, as well as the pure water flow and wastewater flow of the water purifier under the output voltage.

[0068] Step 208, when the pure water flow rate is greater than or equal to the set flux of the water purifier and the pure-to-waste ratio is greater than or equal to the set pure-to-waste ratio of the water purifier, the output voltage is determined as the target output voltage of the target controller, wherein the ratio of the pure water flow rate to the wastewater flow rate is the pure-to-waste ratio.

[0069] In the embodiment of the present disclosure, when the pure water flow rate is greater than or equal to the set flux of the water purifier and the pure-to-waste ratio is greater than or equal to the set pure-to-waste ratio of the water purifier, the water purifier can determine the output voltage as the target output voltage of the target controller. The ratio of the pure water flow rate to the waste water flow rate is the pure-to-waste ratio.

[0070] Step 209, when the pure water flow rate is less than the set flux of the water purifier or the pure-waste ratio is less than the set pure-waste ratio of the water purifier, the output voltage is boosted in the order of voltage from small to large in the voltage gradient until the pure water flow rate is greater than or equal to the set flux of the water purifier and the pure-waste ratio is greater than or equal to the set pure-waste ratio of the water purifier, then the voltage boost is stopped, wherein the ratio of the pure water flow rate to the waste water flow rate is the pure-waste ratio.

[0071] Step 210: Determine the output voltage when boosting is stopped as the target output voltage of the target controller.

[0072] In the embodiment of the present disclosure, the water purifier may determine the output voltage when the voltage boost is stopped as the target output voltage of the target controller.

[0073] Therefore, according to the relationship curve between the output voltage of the controller in the existing multiple water purifiers with different fluxes and the pre-membrane pressure of the filter membrane, the boost strategy of the target controller in the water purifier can be determined, and the output voltage of the target controller can be boosted smoothly to avoid excessive torque generated by the output voltage being too high, thereby affecting the performance of the filter membrane. According to the pure water flow rate, wastewater flow rate generated by the water purifier and the output voltage provided by the controller to the water pump, the actual output voltage provided by the controller in the water purifier to the water pump can be determined, and then the water pressure output by the water pump to the filter membrane can be controlled to achieve the set flux and set pure-waste ratio of the water purifier. The controller can adapt to the water purification voltage requirements of water purifiers with different fluxes. A controller and a water pump of one specification can meet the set flux and set pure-waste ratio of multiple water purifiers with different fluxes, which can reduce the number of specifications of controllers and water pumps required to be configured for water purifiers with different fluxes and reduce costs.

[0074] In some embodiments of the present disclosure, after determining the target output voltage of the target controller based on the pure water flow, waste water flow and output voltage, the water purifier can control the target controller to provide the target output voltage to the target water pump in response to receiving a water purification instruction, so as to achieve the set flux and set pure-waste ratio of the water purifier based on the target output voltage.

[0075] Figure 41 is a schematic diagram of a structure of a self-adaptive device for output voltage of a water purifier controller provided by an embodiment of the present disclosure. The device can be understood as a partial functional module in the above-mentioned water purifier or the above-mentioned computer device.

[0081] Or, a pressure reduction module is used to reduce the output voltage provided to the target water pump by the target controller in the water purifier when the pressure before the membrane is greater than the maximum pressure value of the normal working pressure range of the filter membrane, so that the pressure before the membrane of the filter membrane is within the normal working pressure range.
