Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically providing a control method for a water purification device and the water purification device itself. Background Technology

[0002] As people's living standards improve, water purifiers have gradually become one of the indispensable household appliances in people's daily lives.

[0003] A countertop water purifier is a type of water purifier, typically placed on a countertop for users to dispense water. It features a storage tank to store raw water. This raw water is filtered through the purifier's filter cartridges to produce purified water for drinking. The concentrated water produced by the filter cartridges returns to the storage tank. Water purifiers are usually made of translucent materials. Because they are placed on a countertop, sunlight directly shines on the storage tank. Under sunlight, the water in the tank is prone to the growth of algae, bacteria, and other microorganisms, leading to water contamination. If not cleaned promptly, this can even cause water safety issues.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of algae growth in the water storage tank of existing water purification equipment under sunlight.

[0006] In a first aspect, the present invention provides a control method for a water purification device, characterized in that the water purification device includes a water storage tank, a filter element, a booster pump, and an electrolysis device. The water storage tank has an outlet and a return outlet. The raw water inlet of the filter element is connected to the outlet through a first pipeline, and the concentrated water outlet of the filter element is connected to the return outlet through a second pipeline. The booster pump is installed on the first pipeline, and the electrolysis device is installed in the second pipeline. The electrolysis device is capable of electrolyzing oxidizing substances that kill microorganisms from the concentrated water. The control method includes: obtaining the concentration of the oxidizing substances in the water storage tank, denoted as a first concentration; and selectively activating the electrolysis device according to the first concentration.

[0007] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively activating the electrolysis device according to the first concentration" specifically includes: comparing the first concentration with a preset concentration; and selectively activating the electrolysis device according to the comparison result.

[0008] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively starting the electrolysis device according to the comparison result" specifically includes: if the first concentration is not less than the preset concentration, then the electrolysis device is not started.

[0009] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively starting the electrolysis device according to the comparison result" specifically includes: if the first concentration is less than the preset concentration, then the electrolysis device is started.

[0010] In a preferred embodiment of the control method for the above-mentioned water purification equipment, when it is necessary to start the electrolysis device, the control method further includes: determining whether the booster pump is in the on state; if the booster pump is in the on state, then directly starting the electrolysis device; if the booster pump is in the off state, then starting the booster pump first, and then starting the electrolysis device.

[0011] In a preferred embodiment of the control method for the above-mentioned water purification equipment, after the electrolysis device is started, the control method further includes: after the electrolysis device has been running for a preset time, re-acquiring the concentration of the oxidizing substance in the water storage tank and recording it as a second concentration; and selectively causing the water purification equipment to issue a malfunction warning for the electrolysis device based on the second concentration.

[0012] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively causing the water purification equipment to issue a prompt that the electrolysis device has malfunctioned based on the second concentration" specifically includes: comparing the second concentration with the preset concentration; and selectively causing the water purification equipment to issue a prompt that the electrolysis device has malfunctioned based on the comparison result.

[0013] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively causing the water purification equipment to issue a prompt that the electrolysis device has malfunctioned based on the comparison results" specifically includes: if the second concentration is not less than the preset concentration, then the water purification equipment is not prompted to issue a prompt that the electrolysis device has malfunctioned; if the second concentration is less than the preset concentration, then the water purification equipment is prompted to issue a prompt that the electrolysis device has malfunctioned.

[0014] In a second aspect, the present invention also provides a water purification device, the water purification device including a controller.

[0015] In the preferred embodiment of the above-mentioned water purification equipment, the water purification equipment of the present invention is a tabletop water purifier.

[0016] Those skilled in the art will understand that, in the preferred embodiment of the present invention, the water purification device of the present invention obtains the concentration of oxidizing substances in the water storage tank, i.e., the first concentration, and compares the first concentration with the preset concentration. When the first concentration is less than the preset concentration, it indicates that the oxidizing substances in the water storage tank are consumed in large quantities due to reduction reactions or decomposition, and the efficiency of the oxidizing substances in killing microorganisms is greatly reduced. At this time, the electrolysis device is turned on, and the electrolysis device can electrolyze residual chlorine and other oxidizing substances from the dissolved substances in the concentrated water. The residual chlorine and other oxides can enter the water storage tank through the second pipeline pump, thereby inhibiting the growth of algae and other microorganisms in the water storage tank.

[0017] Furthermore, when the electrolysis device needs to be started, the water purification device of the present invention determines whether the booster pump is in the on state and turns the booster pump on, so that the water in the second pipeline is in a flowing state, thereby enabling the oxidized substances electrolyzed by the electrolysis device to enter the water storage tank more quickly, thereby more effectively inhibiting the growth of algae and other microorganisms in the water storage tank.

[0018] Furthermore, after the electrolysis device has been running for a preset time, the water purification device of the present invention re-obtains the concentration of oxidizing substances in the water storage tank, i.e., the second concentration, and compares the second concentration with the preset concentration. When the second concentration is less than the preset concentration, the electrolysis efficiency of the electrolysis device is greatly reduced due to the large consumption of the electrodes by oxidation and other reasons. At this time, the water purification device issues a fault warning for the electrolysis device, thereby prompting the user to carry out maintenance, thus ensuring the concentration of oxidizing substances in the water storage tank and inhibiting the growth of algae and other microorganisms in the water storage tank.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Based on the background technology, existing water purification equipment's storage tanks suffer from algae growth under sunlight. This invention provides a control method and equipment for a water purification system. The aim is to obtain the concentration of oxidizing substances in the storage tank, i.e., a first concentration, and compare it with a preset concentration. When the first concentration is less than the preset concentration, it indicates that the oxidizing substances in the storage tank have been largely consumed due to reduction reactions or decomposition, significantly reducing their efficiency in killing microorganisms. At this point, an electrolysis device is activated. This device electrolyzes residual chlorine and other oxides from the dissolved substances in the concentrated water. A booster pump then pumps the residual chlorine and other oxidizing substances into the storage tank through a second pipeline, thereby inhibiting the growth of algae and other microorganisms in the storage tank.

[0037] Specifically, such as Figure 1 As shown, the present invention provides a water purification device, which includes a water storage tank 1, a filter element 2, a booster pump 5, and an electrolysis device 3. The water storage tank 1 has an outlet and a return outlet. The raw water inlet and outlet of the filter element 2 are connected through a first pipeline 41, and the concentrated water outlet and return outlet of the filter element 2 are connected through a second pipeline 42. The booster pump 5 is installed on the first pipeline 41, and the electrolysis device 3 is installed in the second pipeline 42. The electrolysis device 3 can electrolyze oxidizing substances that kill microorganisms from the concentrated water.

[0038] For example, such as Figure 1 As shown, the water storage tank 1 of the present invention is vertically arranged and installed on the water purification equipment. The outlet and return water inlet are spaced apart at the bottom of the water storage tank 1, with the outlet on the left and the return water inlet on the right. The outlet of the water storage tank 1 is connected to the raw water inlet of the filter element 2 via a first pipe 41, and the return water inlet of the water storage tank 1 is connected to the concentrated water outlet of the filter element 2 via a second pipe 42. The raw water in the water storage tank 1 enters the raw water inlet of the filter element 2 through the first pipe 41. Under the filtration of the filter element 2, the raw water is filtered into pure water and flows out from the pure water outlet of the filter element 2. The filter element 2 produces... The concentrated water flows back to the storage tank 1 through the concentrated water outlet and the second pipeline 42. The booster pump 5 is installed on the first pipeline 41, and the electrolysis device 3 is installed in the second pipeline 42. The concentrated water contains a large amount of dissolved solids. Through the electrolysis of the electrolysis device 3, the dissolved solids can be electrolyzed to produce oxides such as residual chlorine. The booster pump 5 can pump the oxides such as residual chlorine into the storage tank 1 through the second pipeline 42. The oxides such as residual chlorine can kill algae, bacteria and other microorganisms in the water of the storage tank 1, thereby achieving a sterilization effect and ensuring the safety of the water quality in the storage tank 1.

[0039] Preferably, such as Figure 1 As shown, the water purification device of the present invention also includes a water purification tank 6. The water inlet of the water purification tank 6 is connected to the pure water outlet of the filter element 2 through a third pipe 43, and the water outlet of the water purification tank 6 is connected to the water outlet of the water purification device through a fourth pipe 44.

[0040] For example, such as Figure 1 As shown, the pure water outlet of the filter element 2 of the present invention is connected to the inlet of the water tank 6 through the third pipe 43, and the outlet of the water tank 6 is connected to the outlet of the water purification equipment through the fourth pipe 44. The water storage tank 1 can store the water filtered by the filter element 2, thereby enhancing the pure water storage capacity of the water purification equipment and improving the user's experience.

[0041] It should be noted that when the purified water in the water purification tank 6 reaches its maximum capacity, the booster pump 5 is turned off. When the electrolysis device 3 needs to be turned on for electrolysis, the booster pump 5 is turned on. At this time, the water filtered by the filter element 2 no longer flows into the water purification tank 6, but flows back into the water storage tank 1 through the second pipeline 42. The electrolysis device 3 can electrolyze the water in the second pipeline 42 to produce oxidizing substances that kill microorganisms, and the oxidizing substances flow back into the water storage tank 1, thereby ensuring the concentration of oxidizing substances in the water storage tank 1 and ensuring the safety of the water quality in the water storage tank 1.

[0042] Preferably, such as Figure 1 As shown, the water purification device of the present invention also includes a water pump 7, which is installed on the fourth pipeline 44.

[0043] For example, such as Figure 1 As shown, the fourth pipeline 44 of the present invention is equipped with a water pump 7, which can pump the purified water in the purified water tank 6 into the outlet of the water purification equipment, thereby improving the water output efficiency of the water purification equipment.

[0044] Preferably, such as Figure 1 As shown, the water purification device of the present invention also includes a heating component 8, which is disposed on the fourth pipeline 44 and located downstream of the water pump 7 along the water flow direction.

[0045] For example, such as Figure 1 As shown, the fourth pipe 44 of the present invention is provided with a heating component 8, which can heat the pure water in the fourth pipe 44, thereby enabling the water purification equipment to provide pure water at different temperatures and expanding the functionality of the water purification equipment.

[0046] It should be noted that the present invention does not limit the type of heating element 8. For example, those skilled in the art can set the heating element 8 as a heating plate or heating wire, etc. Such adjustments and changes to the specific type of heating element 8 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0047] Preferably, such as Figure 1 As shown, the electrolysis device 3 of the present invention includes a housing and electrodes installed inside the housing. When the electrodes are connected to a power source in the concentrated water, they can electrolyze the concentrated water to produce oxides.

[0048] For example, such as Figure 1 As shown, the electrodes of the electrolysis device 3 of the present invention are immersed in concentrated water. When the electrodes are energized, they can electrolyze the soluble solids in the concentrated water to produce oxides such as residual chlorine. Then, the oxides such as residual chlorine enter the water storage tank 1 through the second pipeline 42, which can kill algae and other microorganisms in the water storage tank 1.

[0049] On the other hand, based on the water purification equipment described above, the present invention also provides a control method for the water purification equipment, such as... Figure 2 As shown, the control method of the present invention includes the following steps:

[0050] S100: Obtain the concentration of the oxidizing substance in the water storage tank 1, i.e., the first concentration M1.

[0051] For example, the water purification equipment of the present invention is equipped with a concentration detection device, which can detect the concentration of oxidizing substances in the water storage tank 1 and transmit the detection result to the controller of the water purification equipment.

[0052] It should be noted that the present invention does not limit the type of concentration detection device. For example, those skilled in the art can use instruments such as densitometers or concentration testers. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0053] It should also be noted that the present invention does not limit the method for detecting the concentration of oxidizing substances in the water storage tank 1. For example, those skilled in the art can detect it once a day or once every two days, or detect it multiple times within a set time, such as 5 times within 10 minutes, and take the average concentration of the 5 times as the first concentration M1, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0054] S200: Selectively start the electrolysis unit 3 according to the first concentration M1.

[0055] For example, the first concentration M1 can be compared with the preset concentration M, or the first concentration M1 can be divided by the preset concentration M to obtain a ratio, and then the ratio can be compared with the preset value, and so on.

[0056] For example, such as Figure 3 As shown, step S200 includes steps S210 to S230.

[0057] S210: Compare the first concentration M1 with the preset concentration M.

[0058] In other words, the first concentration M1 is compared with the preset concentration M, and the electrolysis device 3 is started based on the comparison result.

[0059] S220: If the first concentration M1 is not less than the preset concentration M, then the electrolysis device 3 will not be started.

[0060] For example, the concentration M1 detected by the concentration detection device is 0.6 ppm, the preset concentration M is 0.5 ppm, and M1 > M, indicating that the concentration of oxidizing substances in the water storage tank 1 is within a suitable range and can effectively kill microorganisms in the water storage tank 1. At this time, it is not necessary to start the electrolysis device 3 to electrolyze the oxidizing substances.

[0061] S230: If the first concentration M1 is less than the preset concentration M, then start the electrolysis device 3.

[0062] For example, the concentration M1 detected by the concentration detection device is 0.05 ppm, the preset concentration M is 0.5 ppm, M1 < M, indicating that the concentration of oxidizing substances in the water storage tank 1 is low and cannot effectively kill the microorganisms in the water storage tank 1. At this time, it is necessary to start the electrolysis device 3 to electrolyze the oxidizing substances.

[0063] It should be noted that the present invention does not limit the value of the preset concentration M. For example, those skilled in the art can directly set the preset concentration M to a value between 0.2 ppm and 2 ppm. Of course, the higher the value of the preset concentration M, the better the effect of the oxidizing substance in killing microorganisms. However, when the preset concentration M is too high, the filtration efficiency of the filter element 2 will be greatly reduced when the filter element 2 of the water purification device does not have activated carbon. Therefore, those skilled in the art can set it according to the actual situation. Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0064] Preferably, when it is necessary to start the electrolysis unit, the control method further includes the following steps:

[0065] S300: Determine whether booster pump 5 is in the on state.

[0066] In other words, the booster pump 5 can increase the water pressure in the pipeline, thereby enabling the oxidized substances electrolyzed by the electrolysis device 3 to be delivered into the water storage tank 1 more quickly.

[0067] S400: If the booster pump 5 is in the on state, the electrolysis device 3 will be started directly.

[0068] In other words, when the booster pump 5 is turned on, it can increase the water pressure in the pipeline, pump the water in the water storage tank 1 into the filter element 2 for filtration, and pump the concentrated water into the water storage tank 1. When the water in the purified water tank 6 reaches its maximum capacity, the booster pump 5 can pump the water in the water storage tank 1 into the filter element 2 and then pump it back into the water storage tank 1. The electrolysis device 3 can electrolyze the water in the second pipeline 42 to produce oxidizing substances that kill microorganisms, and send the oxidizing substances into the water storage tank 1 through the booster pump 5, thereby inhibiting the growth of algae and other microorganisms in the water storage tank 1.

[0069] S500: If booster pump 5 is in the off state, start booster pump 5 first, and then start electrolysis device 3.

[0070] In other words, when the booster pump 5 is off, the water in the second pipeline 42 is in a state of slight flow or no flow. At this time, the electrolysis efficiency of the electrolysis device 3 will gradually decrease, and only a small amount of oxidizing substances can enter the water storage tank 1. Before turning on the electrolysis device 3, the booster pump 5 needs to be turned on to improve the electrolysis efficiency and to send the oxidizing substances electrolyzed by the electrolysis device 3 into the water storage tank 1 more quickly, thereby ensuring the effect of the oxidizing substances in killing algae and other microorganisms in the water storage tank 1.

[0071] It should be noted that the electrolysis device 3 can also produce residual chlorine and other oxides when electrolyzing water that has not been filtered by the filter element 2. However, the total dissolved solids (TDS) content in the concentrated water is high. The electrolysis device 3 can electrolyze more residual chlorine by electrolyzing the concentrated water. Residual chlorine has a strong ability to inhibit the growth of algae, thus killing algae and other microorganisms in the water storage tank 1 more efficiently.

[0072] Preferably, after the electrolysis device 3 is turned on, and after the electrolysis device 3 has been running for a preset time t, the control method further includes the following steps:

[0073] S600: Reacquire the concentration of oxidizing substances in water storage tank 1, i.e., the second concentration M2.

[0074] For example, 30 minutes after the electrolysis device 3 is turned on, the concentration detection device re-detects the concentration of oxidants in the water storage tank 1 and transmits the detection result to the controller of the water purification equipment.

[0075] It should be noted that the present invention does not limit the value of the preset time t. For example, those skilled in the art can set the preset time t to a fixed value, such as 30 minutes or 40 minutes, etc. Within the preset time t, the electrolysis device 3 can electrolyze enough oxidizing substances to ensure the concentration of oxidizing substances in the water storage tank 1. Alternatively, the preset time t can be calculated according to the model of different water purification equipment. For example, taking residual chlorine as the oxidizing substance, the amount of residual chlorine y electrolyzed by the electrolysis device 3 under constant current in a unit time is a fixed value, the capacity of the water storage tank 1 is L, the preset concentration of residual chlorine is a, the actual concentration of residual chlorine is a1, and the flow rate of concentrated water in the second pipeline 42 is v. Then, the preset time t = L*(a-a1) / (y*λ*v), where λ is the electrode life coefficient.

[0076] S700: Based on the second concentration M2, selectively cause the water purification equipment to issue a warning that the electrolysis device 3 has malfunctioned.

[0077] For example, the second concentration M2 can be compared with the preset concentration M, or the second concentration M2 can be divided by the preset concentration M to obtain a ratio, and the ratio can be compared with the preset value, etc., so as to determine whether the electrolysis effect of the electrolysis device 3 meets the requirements.

[0078] For example, step S700 includes steps S710 to S730.

[0079] S710: Compare the second concentration M2 with the preset concentration M.

[0080] In other words, when the second concentration M2 is not less than the preset concentration M, it means that the amount of oxidizing substance electrolyzed by the electrolysis device 3 meets the requirements, and the oxidizing substance in the water storage tank 1 can effectively kill the microorganisms in the water storage tank 1. When the second concentration M2 is less than the preset concentration M, it means that the amount of oxidizing substance electrolyzed by the electrolysis device 3 does not meet the requirements, and the concentration of oxidizing substance in the water storage tank 1 is low, which cannot effectively kill the microorganisms in the water storage tank 1.

[0081] S720: If the second concentration M2 is not less than the preset concentration M, the water purification equipment will not issue a warning that the electrolysis device 3 has malfunctioned.

[0082] For example, the concentration M2 detected by the concentration detection device is 0.6 ppm, the preset concentration M is 0.5 ppm, M2 > M, indicating that the amount of oxidizing substance electrolyzed by the electrolysis device 3 meets the requirements, the concentration of oxidizing substance in the water storage tank 1 is within a suitable range, and it can effectively kill the microorganisms in the water storage tank 1. At this time, it is not necessary to start the electrolysis device 3 to electrolyze the oxidizing substance.

[0083] S730: If the second concentration M2 is less than the preset concentration M, the water purification equipment will issue a warning that the electrolysis device 3 has malfunctioned.

[0084] For example, the concentration M2 detected by the concentration detection device is 0.2 ppm, while the preset concentration M is 0.5 ppm. Since M2 < M, it indicates that the amount of oxidizing substance electrolyzed by the electrolysis device 3 does not meet the requirements, the concentration of oxidizing substance in the water storage tank 1 is low, and the electrolysis efficiency of the electrode of the electrolysis device 3 is greatly reduced due to long-term oxidation. At this time, the water purification equipment issues a fault warning for the electrolysis device 3, thereby prompting the user to replace the electrode of the electrolysis device 3 to ensure the electrolysis efficiency of the electrolysis device 3.

[0085] Preferably, the water purification device of the present invention further includes a controller, which is capable of controlling the water purification device to perform any of the control methods described above.

For example, any of the claimed embodiments in the claims of this application can be used in any combination.
