Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to a water purifier and a control method, device and computer-readable storage medium thereof. Background Art

[0002] The water purifier filters tap water through a composite filter element and an RO membrane filter element. The composite filter element can filter impurities, sediment, and suspended matter in tap water, and the RO membrane filter element can filter some ions and bacteria in the water, reducing the organic content in the water. However, the filter element has a service life. The filtering effect of the composite filter element and the RO membrane filter element will deteriorate after filtering a certain amount of water or using it for a certain period of time. At this time, the user needs to replace the filter element. At present, water purifiers have the function of calculating the service life of the filter element. When the service life of the filter element expires, the corresponding light on the panel will flash to remind the user that the filter element has expired and needs to be replaced. After replacing the filter element, the user needs to manually reset the filter element. Resetting the filter element has two functions. The first is to make the panel light no longer flash (the flashing light means that the service life of the filter element has expired), and the second is to let the water purifier restart the calculation of the service life of the replaced filter element.

[0003] At present, most water purifiers on the market require users to actively reset the filter cartridge on the entire machine after replacing the filter cartridge, which increases the user's operation steps. When the user forgets to reset the filter cartridge, the entire machine will not calculate the service life of the newly replaced filter cartridge in time, resulting in inaccurate calculation of the filter cartridge service life. Summary of the invention

[0004] In view of this, the present invention provides a water purifier and its control method, device and computer-readable storage medium to solve the problem that the existing water purifier requires the user to manually reset the filter element after replacing the filter element, which increases the user's operation steps. When the user forgets to reset the filter element, the whole machine will not calculate the service life of the newly replaced filter element in time, resulting in inaccurate calculation of the filter element service life.

[0005] A first aspect of the present invention provides a water purifier, comprising a filter element assembly, a flow rate detection assembly, a control panel and a reset unit, wherein the flow rate detection assembly is used to detect the water flow rate of the filter element assembly, the control panel is connected to both the filter element assembly and the flow rate detection assembly, the control panel can detect the life of the filter element assembly, the reset unit is communicatively connected to the control panel, the reset unit is used to execute a reset procedure, based on the control panel detecting that the life of the filter element assembly has expired and the flow rate detection assembly detecting that the water flow rate of the filter element assembly has suddenly increased, the control panel controls the reset unit to execute the reset procedure so that the control panel recalculates the life of the replaced filter element assembly.

[0006] Beneficial effect: The water purifier of the present application can detect the expiration of the life of the filter element assembly through the control panel when the life of the filter element assembly expires, and at this time, if the flow rate detection assembly detects that the water flow rate through the filter element assembly suddenly increases, the control panel controls the reset unit to execute the reset program, so that the control panel recalculates the life of the replaced filter element assembly. Therefore, the water purifier of the present application can automatically reset after replacing the filter element assembly without manual operation by the user, thereby improving the user experience and avoiding the problem that the user forgets to manually reset, resulting in the whole machine failing to calculate the service life of the newly replaced filter element in time, resulting in inaccurate calculation of the filter element service life.

[0007] In some embodiments, the water purifier further includes a water purification pipeline, the filter element assembly and the flow rate detection assembly are both arranged in the water purification pipeline, and the flow rate detection assembly is located downstream of the filter element assembly.

[0008] Beneficial effect: By connecting the filter element assembly and the flow rate detection assembly in series to the water purification pipeline, and the flow rate detection assembly is located downstream of the filter element assembly, it is convenient for the flow rate detection assembly to detect the water flow rate of the filter element assembly.

[0009] In some embodiments, the clean water pipeline includes a raw water pipeline and a coarse filtration pipeline, the filter element assembly includes a pre-filter element, the first water inlet of the pre-filter element is connected to the raw water pipeline, the first water outlet of the pre-filter element is connected to the coarse filtration pipeline, and the flow rate detection assembly includes a first flow rate detection element, and the first flow rate detection element is arranged in the coarse filtration pipeline.

[0010] Beneficial effect: raw water flows into the pre-filter through the raw water pipeline and the first water inlet for coarse filtration. The raw water after coarse filtration flows into the coarse filtration pipeline from the first water outlet. The first flow rate detection component arranged on the coarse filtration pipeline can detect the flow rate of the outflowing raw water, which is the water flow rate of the pre-filter.

[0011] In some embodiments, the water purification pipeline includes a fine filtration pipeline, the filter element assembly also includes a fine filter element, the fine filter element has a fine filter element water inlet and a pure water inlet, the fine filter element water inlet is connected to the coarse filtration pipeline, the pure water inlet is connected to the fine filtration pipeline, and the flow rate detection assembly includes a second flow rate detection element, and the second flow rate detection element is arranged in the fine filtration pipeline.

[0012] Beneficial effect: the raw water after coarse filtration flows into the fine filter element through the coarse filtration pipeline and the water inlet of the fine filter element for deep filtration, and the filtered pure water flows into the fine filtration pipeline from the pure water inlet. The second flow rate detection component arranged on the fine filtration pipeline can detect the flow rate of the outflowing pure water, which is the water flow rate of the fine filter element.

[0013] In some embodiments, the clean water pipeline also includes a pure water pipeline, and the filter element assembly also includes a post-filter element, the second water inlet of the post-filter element is connected to the fine filtration pipeline, and the second water outlet of the post-filter element is connected to the pure water pipeline.

[0014] Beneficial effect: the pure water flowing out of the fine filter element flows into the post-filter element through the fine filtration pipeline and the second water inlet for re-filtration, and the filtered pure water flows into the pure water pipeline through the second water outlet for use by users.

[0015] In some embodiments, the first flow rate detecting component and / or the second flow rate detecting component is a flow meter.

[0016] Beneficial effect: It is very convenient to use a flow meter to detect the water flow rate of the pre-filter and / or fine filter. Specifically, the flow meter is used to count the number of pulses f per second, and the flow meter calculation formula is used to determine how many liters of water flow through the pre-filter and / or fine filter per second, thereby determining the water flow rate of the pre-filter and / or fine filter.

[0017] A second aspect of the present invention provides a control method for controlling the water purifier of the present invention, the control method comprising:

[0018] Determine whether the life of the filter element assembly has expired;

[0019] If yes, obtaining the water flow rate of the filter element assembly;

[0020] Determining whether the water flow rate of the filter element assembly suddenly increases;

[0021] If so, perform a reset procedure to recalculate the life of the replaced filter element assembly.

[0022] Since the control method of the present application is used to control the water purifier of the present application, it has the same technical effect as the water purifier, and the present application will not repeat it here.

[0023] In some embodiments, the filter element assembly includes a pre-filter element and / or a fine filter element, and the step of determining whether the life of the filter element assembly has expired includes: determining whether the life of the pre-filter element and / or the fine filter element has expired.

[0024] Beneficial effect: By judging whether the service life of the pre-filter element and / or the fine filter element has expired, the pre-filter element and / or the fine filter element can be replaced in time when the service life of the pre-filter element and / or the fine filter element has expired to ensure the quality of purified water.

[0025] In some embodiments, if yes, the step of obtaining the water flow rate of the filter element assembly includes: if yes, obtaining the water flow rate of the pre-filter element and / or the fine filter element.

[0026] Beneficial effect: Since the filter element assembly includes a pre-filter element and / or a fine filter element, obtaining the water flow rate of the filter element assembly includes obtaining the water flow rate of the pre-filter element and / or the fine filter element to further determine whether the pre-filter element and / or the fine filter element needs to be replaced.

[0027] In some embodiments, the step of determining whether the water flow rate of the filter element assembly suddenly increases includes: determining whether the real-time water flow rate of the filter element assembly is greater than the water flow rate of the filter element assembly in the previous second.

[0028] Beneficial effect: If it is determined that the real-time water flow rate of the filter element assembly is greater than the water flow rate of the filter element assembly in the previous second, it is concluded that the water flow rate of the filter element assembly has suddenly increased, and it is concluded that the filter element assembly has been replaced, and the next step can be performed.

[0029] In some embodiments, if yes, the step of performing a reset procedure to recalculate the life of the replaced filter element assembly includes:

[0030] If yes, determining whether the water flow rate of the filter element assembly is greater than or equal to a preset flow rate;

[0031] If so, perform a reset procedure to recalculate the life of the replaced filter element assembly.

[0032] Beneficial effect: Since whether to replace the filter element assembly is determined only by judging whether the water flow rate of the filter element assembly suddenly increases, there may be misjudgment. Therefore, in order to improve the accuracy of the judgment, a judgment condition is added under the condition that the water flow rate of the filter element assembly suddenly increases, that is, to further judge whether the water flow rate of the filter element assembly is greater than or equal to the preset flow rate. If so, the reset procedure is executed to recalculate the life of the replaced filter element assembly.

[0033] In some embodiments, if yes, in the step of determining whether the water flow rate of the filter element assembly is greater than or equal to a preset flow rate, the preset flow rate is the average water flow rate of the unused filter element assembly within a preset time period.

[0034] Beneficial effect: When the water flow rate of the filter element assembly is greater than or equal to the average water flow rate of the unused filter element assembly within a preset time period, it can be determined that the filter element assembly has been replaced, and a reset procedure can be executed to facilitate the calculation of the life of the replaced filter element assembly.

[0035] In some embodiments, the step of determining whether the life of the filter element assembly has expired includes: determining whether the usage time of the filter element assembly has reached a preset time.

[0036] Beneficial effect: It is very convenient to judge whether the service life of the filter element assembly has expired by judging whether the service life of the filter element assembly has reached a preset time.

[0037] A third aspect of the present invention provides a control device, which is used to implement the above control method, and the control device includes:

[0038] A judgment module, used to judge whether the service life of the filter element assembly has expired and whether the water flow rate of the filter element assembly has suddenly increased;

[0039] An acquisition module, used for acquiring the water flow rate of the filter element assembly;

[0040] The reset module is used to execute the reset procedure.

[0041] Since the control device of the present application is used to implement the control method of the present application, it has the same technical effect as the control method, and the present application will not elaborate on it here.

[0042] A fourth aspect of the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and when the computer instructions are executed, the above-mentioned control method is implemented.

[0043] Since the computer-readable storage medium of the present application stores computer instructions, when the computer instructions are executed, the above-mentioned control method is implemented, and thus has the same technical effect as the control method, and the present application will not repeat them here.

[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0061] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0064] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0065] like Figures 1 to 3 As shown, according to an embodiment of the present invention, on the one hand, a water purifier is disclosed, including a filter element assembly, a flow rate detection assembly, a control panel and a reset unit, wherein the flow rate detection assembly is used to detect the water flow rate of the filter element assembly, the control panel is connected to both the filter element assembly and the flow rate detection assembly, the control panel can detect the life of the filter element assembly, the reset unit is communicatively connected to the control panel, the reset unit is used to execute a reset program, based on the control panel detecting that the life of the filter element assembly has expired, and the flow rate detection assembly detecting that the water flow rate of the filter element assembly has suddenly increased, the control panel controls the reset unit to execute the reset program, so that the control panel recalculates the life of the replaced filter element assembly.

[0066] The water purifier of the present application can detect the expiration of the life of the filter element assembly through the control panel when the life of the filter element assembly expires, and at this time, if the flow rate detection assembly detects that the water flow rate through the filter element assembly suddenly increases, the control panel controls the reset unit to execute the reset program, so that the control panel recalculates the life of the replaced filter element assembly. Therefore, the water purifier of the present application can automatically reset after replacing the filter element assembly without manual operation by the user, thereby improving the user experience and avoiding the problem that the user forgets to manually reset, resulting in the whole machine failing to calculate the service life of the newly replaced filter element in time, resulting in inaccurate calculation of the filter element service life.

[0067] It should be noted that the water flow rate is the speed of water flowing through the filter element assembly. The control panel detects the life of the filter element assembly and the reset unit performs the reset procedure and other technologies are common knowledge in the art and will not be elaborated in this embodiment.

[0068] In some embodiments, the water purifier further includes a water purification pipeline, the filter element assembly and the flow rate detection assembly are both arranged in the water purification pipeline, and the flow rate detection assembly is located downstream of the filter element assembly.

[0069] By connecting the filter element assembly and the flow rate detection assembly in series to the water purification pipeline, and locating the flow rate detection assembly downstream of the filter element assembly, the flow rate detection assembly can conveniently detect the water flow rate of the filter element assembly.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the clean water pipeline includes a raw water pipeline 100 and a coarse filtration pipeline 200, the filter element assembly includes a pre-filter element 11, the first water inlet 13 of the pre-filter element 11 is connected to the raw water pipeline 100, the first water outlet 14 of the pre-filter element 11 is connected to the coarse filtration pipeline 200, and the flow rate detection assembly includes a first flow rate detection element 3, and the first flow rate detection element 3 is arranged in the coarse filtration pipeline 200.

[0071] The raw water flows into the pre-filter element 11 through the raw water pipeline 100 and the first water inlet 13 for coarse filtration. The raw water after coarse filtration flows into the coarse filtration pipeline 200 from the first water outlet 14. The first flow rate detection element 3 arranged on the coarse filtration pipeline 200 can detect the flow rate of the outflowing raw water, which is the water flow rate of the pre-filter element 11.

[0072] In this embodiment, the raw water pipeline 100 is connected to tap water, and the raw water is tap water, but it is not limited to this. For example, the raw water pipeline 100 can also be connected to well water, and the raw water is well water in this case.

[0073] like Figure 1 and Figure 3 As shown, in some embodiments, the water purification pipeline includes a fine filtration pipeline 300, the filter element assembly also includes a fine filter element 2, the fine filter element 2 has a fine filter element water inlet 21 and a pure water inlet 22, the fine filter element water inlet 21 is connected to the coarse filtration pipeline 200, the pure water inlet 22 is connected to the fine filtration pipeline 300, and the flow rate detection assembly includes a second flow rate detection element 4, and the second flow rate detection element 4 is arranged in the fine filtration pipeline 300.

[0074] The raw water after coarse filtration flows into the fine filter element 2 through the coarse filtration pipeline 200 and the fine filter element water inlet 21 for deep filtration, and the filtered pure water flows into the fine filtration pipeline 300 from the pure water inlet 22. The second flow rate detection component 4 arranged on the fine filtration pipeline 300 can detect the flow rate of the outflowing pure water, which is the water flow rate of the fine filter element 2.

[0075] In some embodiments, the clean water pipeline also includes a pure water pipeline 400, and the filter element assembly also includes a post-filter element 12, the second water inlet 15 of the post-filter element 12 is connected to the fine filtration pipeline 300, and the second water outlet 16 of the post-filter element 12 is connected to the pure water pipeline 400.

[0076] The pure water flowing out of the fine filter element 2 flows into the post-filter element 12 through the fine filtration pipeline 300 and the second water inlet 15 for re-filtration, and the filtered pure water flows into the pure water pipeline 400 through the second water outlet 16 for use by users.

[0077] Specifically, the pre-filter element 11 can be a filter element synthesized from PP cotton, activated carbon, and ultrafiltration, which can adsorb impurities such as mud and sand in the raw water, and can also remove residual chlorine in the raw water to achieve coarse filtration of the raw water.

[0078] The post-filter 12 can filter the pure water again to remove trace elements, adjust the pH value and drinking taste. For example, the post-filter 12 can be a filter containing activated carbon components.

[0079] Preferably, the pre-filter element 11 and the post-filter element 12 can be integrated to form a composite filter element 1, so as to reduce the volume of the water purifier and make the structure of the whole machine highly integrated. Specifically, the composite filter element 1 has a filter housing, and the pre-filter element 11 and the post-filter element 12 are independently arranged in the filter housing.

[0080] The fine filter element 2 has a higher filtering accuracy than the pre-filter element 11. The fine filter element 2 is arranged downstream of the pre-filter element 11 and can further deeply purify the raw water filtered by the pre-filter element 11. It is the core processing filter element of the water purifier.

[0081] The specific form, for example, the fine filter element 2 can be a reverse osmosis membrane filter element (RO filter element), a nanofiltration membrane filter element or a ceramic filter element, etc., which is selected according to the filtering requirements and is not specifically limited in this embodiment.

[0082] Since the particle size of the fine filter element 2 is very small and the resistance of raw water passing through is relatively large, a pressure-stabilizing pump 6 is provided on the coarse filtration pipeline 200. The pressure-stabilizing pump 6 is located downstream of the first flow velocity detection element 3. The pressure-stabilizing pump 6 is used to increase the pressure of the raw water so that it can pass through the fine filter element 2 more easily, thereby improving the filtration efficiency.

[0083] In some embodiments, a water inlet solenoid valve 5 is further provided on the coarse filtration pipeline 200 , and the water inlet solenoid valve 5 is located between the pressure-stabilizing pump 6 and the first flow rate detection component 3 .

[0084] The water inlet solenoid valve 5 can control and regulate the raw water flowing to the fine filter element 2, and can also cut off the coarse filter pipeline 200 when the water purifier stops working, so as to prevent the raw water from continuing to flow into the fine filter element 2 and causing damage to the filter element.

[0085] In some embodiments, the fine filter element 2 further has a wastewater port 23 , and the clean water pipeline further includes a wastewater pipeline 600 , and the wastewater pipeline 600 is connected to the wastewater port 23 .

[0086] When the fine filter element 2 is filtering, corresponding waste water will be generated. The waste water will flow into the waste water pipeline 600 through the waste water port 23 and will be discharged to the outside through the waste water pipeline 600.

[0087] A wastewater solenoid valve 7 is provided on the wastewater pipeline 600 , and the wastewater solenoid valve 7 is used to control the connection or disconnection of the wastewater pipeline 600 .

[0088] In some embodiments, the first flow rate detecting component 3 and / or the second flow rate detecting component 4 is a flow meter.

[0089] It is very convenient to use a flow meter to detect the water flow rate of the pre-filter element 11 and / or the fine filter element 2. Specifically, the flow meter is used to count the number of pulses f per second, and the flow meter calculation formula is used to determine how many liters of water flow through the pre-filter element 11 and / or the fine filter element 2 per second, thereby determining the water flow rate of the pre-filter element 11 and / or the fine filter element 2.

[0090] In addition to the above-mentioned configuration, the water purifier of this embodiment further includes a water purification branch 500, which is connected to the coarse filtration pipeline 200. Part of the raw water in the coarse filtration pipeline 200 can flow out through the water purification branch 500 for user use (washing vegetables, washing dishes, etc.).

[0091] Specifically, the connection point between the clean water branch 500 and the coarse filtration pipeline 200 is located between the first flow velocity detection component 3 and the water inlet solenoid valve 5, but it is not limited thereto.

[0092] For example, in other embodiments, the connection between the clean water branch 500 and the coarse filtration pipeline 200 can also be located upstream of the first flow rate detection component 3, or between the water inlet solenoid valve 5 and the pressure-stabilizing pump 6, or downstream of the pressure-stabilizing pump 6.

[0093] To facilitate understanding of the water purifier of this embodiment, its working principle is now introduced as follows:

[0094] In normal water purification of the water purifier, raw water (such as tap water) flows into the pre-filter element 11 through the raw water pipeline 100 and the first water inlet 13 for coarse filtration to remove impurities such as mud and sand in the raw water and to remove residual chlorine in the raw water. The filtered raw water flows into the coarse filtration pipeline 200 through the first water outlet 14, and part of the raw water flows into the purified water branch 500 along the coarse filtration pipeline 200 and flows out for user use (washing vegetables, washing dishes, etc.). Part of the raw water flows through the first flow rate detection component 3, the water inlet solenoid valve 5, and the pressure regulating pump in sequence. 6. The water flows into the fine filter element 2 from the water inlet 21 for deep purification to remove organic matter, pigments and other substances in the raw water. The waste water formed flows into the waste water pipeline 600 through the waste water outlet 23 for discharge. The pure water formed flows through the pure water outlet 22, the fine filtration pipeline 300 and the second water inlet 15 in turn and then flows into the post-filter element 12 for further filtration to remove trace elements in the pure water, adjust the pH value and the drinking taste. The filtered pure water flows through the second water outlet 16 and the pure water pipeline 400 for users to use.

[0095] When the control panel detects that the life of the pre-filter element 11 has expired, the first flow velocity detection component 3 starts to detect the water flow rate of the pre-filter element 11. Due to the expiration of its life, the water flow rate of the pre-filter element 11 tends to decrease. When the first flow velocity detection component 3 detects that the water flow rate of the pre-filter element 11 suddenly increases, it means that the pre-filter element 11 has been replaced. The control panel controls the reset unit to execute the reset program to recalculate the life of the replaced pre-filter element 11.

[0096] When the control panel detects that the life of the fine filter element 2 has expired, the second flow rate detection component 4 starts to detect the water flow rate of the fine filter element 2. Due to the expiration of the life, the water flow rate of the fine filter element 2 tends to decrease. When the second flow rate detection component 4 detects that the water flow rate of the fine filter element 2 suddenly increases, it means that the fine filter element 2 has been replaced. The control panel controls the reset unit to execute the reset program to recalculate the life of the replaced fine filter element 2.

[0097] It should be noted that the life of the pre-filter element 11 and the life of the fine filter element 2 are different, so the life of the pre-filter element 11 and the life of the fine filter element 2 generally will not expire at the same time, and the control programs of the two are carried out separately and independently without interfering with each other.

[0098] like Figures 4 to 6 As shown, according to an embodiment of the present invention, on the other hand, a control method is also disclosed, which is used to control the water purifier of this embodiment. The control method includes the following steps:

[0099] Determine whether the life of the filter element assembly has expired;

[0100] If yes, obtain the water flow rate of the filter element assembly;

[0101] Determine whether the water flow rate of the filter element assembly suddenly increases;

[0102] If yes, perform the reset procedure to recalculate the life of the replaced filter assembly.

[0103] Since the control method of the present application is used to control the water purifier of the present application, it has the same technical effect as the water purifier, and this embodiment will not be repeated here.

[0104] In some embodiments, the filter element assembly includes a pre-filter element 11 and / or a fine filter element 2, and the step of determining whether the life of the filter element assembly has expired includes: determining whether the life of the pre-filter element 11 and / or the fine filter element 2 has expired.

[0105] By judging whether the service life of the pre-filter element 11 and / or the fine filter element 2 has expired, the pre-filter element 11 and / or the fine filter element 2 can be replaced in time when the service life of the pre-filter element 11 and / or the fine filter element 2 has expired to ensure the quality of purified water.

[0106] In this embodiment, the filter element assembly includes a pre-filter element 11 and a fine filter element 2 .

[0107] In some embodiments, if yes, the step of obtaining the water flow rate of the filter element assembly includes:

[0108] If yes, obtain the water flow rate of the pre-filter element 11 and / or the fine filter element 2.

[0109] Since the filter element assembly includes a pre-filter element 11 and / or a fine filter element 2, obtaining the water flow rate of the filter element assembly includes obtaining the water flow rate of the pre-filter element 11 and / or the fine filter element 2 to further determine whether the pre-filter element 11 and / or the fine filter element 2 need to be replaced.

[0110] In this embodiment, the filter element assembly includes a pre-filter element 11 and a fine filter element 2. The water flow rates of the pre-filter element 11 and the fine filter element 2 are not equal, so the water flow rates include a first water flow rate and a second water flow rate. The first water flow rate is the water flow rate of the pre-filter element 11, and the second water flow rate is the water flow rate of the fine filter element 2. Usually, the first water flow rate is greater than the second water flow rate.

[0111] In some embodiments, the step of determining whether the water flow rate through the filter element assembly suddenly increases includes: determining whether the real-time water flow rate through the filter element assembly is greater than the water flow rate through the filter element assembly in the previous second.

[0112] If it is determined that the real-time water flow rate of the filter element assembly is greater than the water flow rate of the filter element assembly last second, it is concluded that the water flow rate of the filter element assembly has suddenly increased, and it is concluded that the filter element assembly has been replaced, and the next step can be performed.

[0113] In this embodiment, the filter element assembly includes a pre-filter element 11 and a fine filter element 2. Therefore, when it is detected that the life of the pre-filter element 11 has expired, and the real-time water flow rate of the pre-filter element 11 is greater than the water flow rate of the pre-filter element 11 in the previous second, it is concluded that the pre-filter element 11 has been replaced, and the reset procedure of the pre-filter element 11 can be executed to recalculate the life of the replaced pre-filter element 11; when it is detected that the life of the fine filter element 2 has expired, and the real-time water flow rate of the fine filter element 2 is greater than the water flow rate of the fine filter element 2 in the previous second, it is concluded that the fine filter element 2 has been replaced, and the reset procedure of the fine filter element 2 can be executed to recalculate the life of the replaced fine filter element 2.

[0114] In some embodiments, if yes, performing a reset procedure to recalculate the life of the replaced filter element assembly comprises the following steps:

[0115] If yes, determine whether the water flow rate of the filter element assembly is greater than or equal to the preset flow rate;

[0116] If yes, perform the reset procedure to recalculate the life of the replaced filter assembly.

[0117] Since whether to replace the filter element assembly is determined solely by judging whether the water flow rate through the filter element assembly suddenly increases, there may be misjudgment. Therefore, in order to improve the accuracy of the judgment, an additional judgment condition is added under the condition that the water flow rate through the filter element assembly suddenly increases, that is, to further judge whether the water flow rate through the filter element assembly is greater than or equal to the preset flow rate. If so, the reset procedure is executed to recalculate the life of the replaced filter element assembly.

[0118] In some embodiments, if yes, in the step of determining whether the water flow rate of the filter element assembly is greater than or equal to a preset flow rate, the preset flow rate is the average water flow rate of the unused filter element assembly within a preset time period.

[0119] When the water flow rate of the filter element assembly is greater than or equal to the average water flow rate of the unused filter element assembly within a preset time period, it can be determined that the filter element assembly has been replaced, and a reset procedure can be executed to facilitate the calculation of the life of the replaced filter element assembly.

[0120] It should be noted that the unused filter element assembly is a brand new filter element assembly, and the average water flow rate of the brand new filter element assembly within a preset time period can be obtained through experiments, and this embodiment does not impose specific restrictions.

[0121] It is understandable that the preset time period here may be 5 seconds, 10 seconds, 15 seconds or 20 seconds, etc., and this embodiment does not make any specific limitation.

[0122] Of course, in other embodiments, the preset flow rate may also be the average water flow rate of a plurality of unused filter element assemblies.

[0123] The average water flow rate of multiple unused filter element assemblies can be obtained by counting the water flow rates of multiple unused filter element assemblies and calculating the average value. The specific value can be obtained through experiments and will not be described in detail in this embodiment.

[0124] In some embodiments, the step of determining whether the life of the filter element assembly has expired includes: determining whether the usage time of the filter element assembly has reached a preset time.

[0125] It is very convenient to judge whether the service life of the filter element assembly has expired by judging whether the usage time of the filter element assembly reaches the preset time.

[0126] In this embodiment, the filter element assembly includes a pre-filter element 11 and a fine filter element 2. The service life of the pre-filter element 11 and the fine filter element 2 is different. For example, the service life of the fine filter element 2 can reach 300 hours, while the service life of the pre-filter element 11 is often less than 300 hours. The preset time of this embodiment includes a first preset time and a second preset time. The first preset time is 300 hours for the fine filter element 2, and the second preset time is less than 300 hours (determined according to the filter element type) for the pre-filter element 11.

[0127] It should be noted here that the service life of the pre-filter element 11 and the fine filter element 2 are not equal, so the life of the pre-filter element 11 and the fine filter element 2 generally will not expire at the same time. Therefore, the control method for determining the expiration and replacement of the pre-filter element 11 and the fine filter element 2 is carried out separately and independently without interfering with each other.

[0128] According to an embodiment of the present invention, in a third aspect, a control device is disclosed, which is used to implement the above-mentioned control method. The control device includes a judgment module, an acquisition module and a reset module. The judgment module is used to judge whether the life of the filter element assembly has expired and whether the water flow rate of the filter element assembly has suddenly increased. The acquisition module is used to obtain the water flow rate of the filter element assembly. The reset module is used to execute a reset procedure.

[0129] Since the control device of the present application is used to implement the control method of the present application, it has the same technical effect as the control method, and the present application will not elaborate on it here.

[0130] According to an embodiment of the present invention, in a fourth aspect, a computer-readable storage medium is disclosed, wherein the computer-readable storage medium stores computer instructions, and when the computer instructions are executed, the above-mentioned control method is implemented.

[0131] Since the computer-readable storage medium of the present application stores computer instructions, when the computer instructions are executed, the above-mentioned control method is implemented, and thus has the same technical effect as the control method, and the present application will not repeat them here.

[0132] Exemplarily, the computer-readable storage medium may be a storage CD, a hard disk, or a USB flash drive, but is not limited thereto.

[0133] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
