Description

Technical Field

[0002] As people pay more attention to water safety, water purifiers with purification function are gradually accepted by the market. Among them, reverse osmosis water purifiers are popular among consumers due to their extremely high water purification accuracy. The core reverse osmosis (RO) filter element plays a filtering role by achieving deep water purification through the nanochannels on the polyamide separation layer on the surface of the reverse osmosis membrane. However, the polyamide separation layer has poor tolerance to oxidizing substances, and its pleated structure is easily damaged. In order to effectively extend the life of the RO filter element, the industry often uses pretreatment to ensure the quality of its inlet water. The water quality requirements mainly include turbidity, SDI15, and residual chlorine.

[0003] The PP cotton and ultrafiltration in the existing water purifier pretreatment filter can effectively reduce the turbidity, SDI15, etc. of water, but only the carbon material filter can effectively remove residual chlorine. Therefore, the carbon filter is an indispensable component of the water purifier pretreatment filter. The water purification performance can be improved to a certain extent from the material, production method and increased dosage of the activated carbon filter. However, the existing technology lacks a general technical solution to how to extend the life of the activated carbon filter and reduce the number of core changes. After the long-term use of the current activated carbon causes the water purification function to completely fail, the generally used technology is to replace the activated carbon or remove the activated carbon and install it, which is costly and requires manual operation and has low efficiency. Summary of the invention

After the long-term use of the current activated carbon causes the water purification function to completely fail, the general method is to replace the activated carbon or remove the activated carbon and install the technology, which is costly, requires manual operation and has low efficiency.

[0005] In a first aspect, the present invention provides a method for regenerating a filter element by hot water, which is applied to a drinking water purification device having a filter element, the method comprising: controlling the drinking water purification device to perform a water replenishment operation of a water storage device until the water volume of the water storage device is greater than a preset water volume threshold, and heating the water in the heating device to a preset temperature value, wherein the water in the heating device is the water in the water storage device flowing out to the heating device; using the water heated to the preset temperature value in the heating device to perform a flushing operation on the filter element, and discharging the water after the flushing operation.

[0006] The filter element hot water regeneration method provided by the present invention controls the water purification equipment to perform the water replenishment operation of the water storage device until the water volume of the water storage device is greater than a preset water volume threshold, and heats the water in the heating device to a preset temperature value, and then uses the reverse flow of the water heated to the preset temperature value in the heating device to perform a flushing operation on the filter element, thereby realizing fully automatic in-situ hot water regeneration without manual operation, thereby increasing the service life of the activated carbon filter element, extending the element replacement cycle, and during the water replenishment operation and the heating of the water to the preset temperature value, it does not restrict the user's normal use, thereby improving the user experience.

[0010] The present invention sets the filter element cleanable time period by combining usage scenarios and user experience. Only when the moment after the water replenishment and heating operation is completed is within the preset filter element cleanable time period, the water storage device will perform water replenishment and heating, and then the subsequent filter element flushing operation will be performed, thereby ensuring that the filter element flushing operation will not affect the user's normal use of the drinking water purification device, thereby improving the user experience.

[0030] 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.

[0031] According to the sanitary standards for drinking water, a certain concentration of residual chlorine must be retained in the tap water before it leaves the factory to ensure the safety of the water quality during transportation. After being disinfected with chlorine, the tap water can ensure the safety of the water quality to a certain extent. However, the complex water supply network and auxiliary equipment such as water storage equipment will inevitably contain pollution such as rust, sediment and organic matter. Therefore, the chlorine disinfectant will continue to react and transform, which is very likely to cause secondary pollution. As people pay more attention to water quality safety, water purifiers with purification functions are gradually accepted by the market. Among them, reverse osmosis water purifiers are favored by consumers because of their extremely high water purification accuracy. Its core reverse osmosis (RO) filter element, the mechanism of its filtering effect is to achieve deep water purification through the nanochannels on the polyamide separation layer on the surface of the reverse osmosis membrane, but the polyamide separation layer has poor tolerance to oxidizing substances, and its pleated structure is easily damaged. In order to effectively extend the life of the RO filter element, the industry often uses pretreatment to ensure its inlet water quality. The water quality requirements mainly include turbidity, SDI15, and residual chlorine.

[0032] The PP cotton and ultrafiltration in the existing water purifier pre-treatment filter can effectively reduce the turbidity, SDI15, etc. of water, but only the carbon material filter can effectively remove residual chlorine. Therefore, the carbon filter is an indispensable component of the water purifier pre-treatment filter. The activated carbon filter material, production method and increased dosage can improve its water purification performance and life to a certain extent, but there are always failure points. Due to the development trend of long life and less replacement of water purifier filter elements, the industry has developed a variety of life extension technologies around ultrafiltration filter elements and reverse osmosis filter elements, but the relevant technology does not have a general technology for extending the life of carbon filter elements. Therefore, it is necessary to find a more effective general technology for extending the life of carbon filter elements.

[0033] The survey results show that the process of activated carbon adsorbing pollutants includes physical adsorption and chemical adsorption. Physical adsorption is the main mechanism of activated carbon in removing pollutants. Changing the conditions can break the adsorption equilibrium and cause the adsorbate to be resolved and detached. The chemical adsorption process is irreversible. In essence, the functional groups on the surface of activated carbon form a stable complex with the pollutant molecules. In the specific process, activated carbon first acts mainly on physical adsorption. When the physical adsorption is close to saturation, chemical adsorption intervenes until it completely fails. In view of the above characteristics, finding external force to break the balance between activated carbon and adsorbate, so that physical adsorption proceeds in the opposite direction, and at the same time slowing down the reaction process of chemical adsorption, so that the activated carbon can be regenerated and the adsorption capacity can be restored, so as to achieve the purpose of extending the service life.

[0034] According to an embodiment of the present invention, an embodiment of a filter element hot water regeneration method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] In this embodiment, a filter element hot water regeneration method is provided, which can be used for the above-mentioned drinking water purification equipment with a filter element. The material of the filter element and the type of drinking water purification equipment are not limited and can be determined according to the actual installation type. In the embodiment of the present invention, the pre-carbon filter element is taken as an example. When the pre-carbon filter element is regenerated by hot water, it is still assembled in the system of the drinking water purification equipment. This is just an example. Figure 1 is a flow chart of a filter element hot water regeneration method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0036] Step S101, controlling the drinking water purification device to perform a water replenishment operation on the water storage device until the water volume in the water storage device is greater than a preset water volume threshold, and heating the water in the heating device to a preset temperature value.

[0037] The water in the heating device is the water in the water storage device flowing out to the heating device.

[0038] The drinking water purification device of the embodiment of the present invention generally displays two states, namely heating and keeping warm. The heating state generally indicates but is not limited to that after the water storage device performs the cold water replenishment operation, the water in the water storage device needs to flow through the heating device and be heated to a preset temperature value. The keeping warm state generally indicates but is not limited to that the water storage device is full of water and the water temperature has been heated to a preset temperature value by the heating device. This is only an example and can be set according to the type of drinking water purification device actually used. When the drinking water purification device responds to executing the filter element cleaning operation, it can pre-determine whether the water volume in the water storage device of the drinking water purification device is greater than the water volume threshold value, and the water in the water storage device flows out of the heating device for heating, and judge whether the water temperature in the heating device reaches the preset temperature value, wherein the water volume threshold value and the preset temperature value are not limited, and can be set according to the use time or material of the filter element. Generally, the water volume threshold value is set to take the water storage device as full as an example, and the preset temperature value is generally between 35-60°C. As an example only, the above judgment method is not limited, and can be determined according to the current status displayed by the drinking water purification device. If it is in the insulation state, it means that the water storage device is full of water and the water temperature of the water in the heating device reaches the preset temperature value, and the subsequent filter element cleaning operation can be performed. As an example only.

[0039] If the embodiment of the present invention determines that the water storage device is in a heating state, it can be determined that the water volume in the water storage device of the drinking water purification device is not greater than the water volume threshold and / or the water temperature in the heating device has not reached the preset temperature value. The drinking water purification device can then be controlled to perform a water replenishment operation on the water storage device until the water volume in the water storage device is greater than the preset water volume threshold. The water temperature can then be heated to the preset temperature value through the heating device in the drinking water purification device. The state of the water storage device in the water replenishment operation or the heating operation may not be displayed on the user end, indicating that the user can still use the drinking water purification device normally under this operation, as an example only.

[0040] Step S102, using water heated to a preset temperature in a heating device to flush the filter element, and draining the water after the flushing operation.

[0041] The embodiment of the present invention determines that the water volume of the water storage device is greater than a preset water volume threshold, and the water in the water storage device flows through the heating device and is heated until the water temperature reaches a preset temperature value. The hot water in the heating device can then be used to reversely flow and flush and regenerate the pre-carbon filter element to restore its adsorption performance and extend its life. Finally, the waste water from flushing the filter element can be discharged through a pipeline.

[0042] The filter element hot water regeneration method provided in the present embodiment controls the water purification equipment to perform the water replenishment operation of the water storage device until the water volume of the water storage device is greater than the preset water volume threshold, and heats the water in the heating device to a preset temperature value, and then uses the water heated to the preset temperature value in the heating device to flow in reverse to perform a flushing operation on the filter element, thereby realizing fully automatic in-situ hot water regeneration without manual operation, thereby increasing the service life of the activated carbon filter element, extending the element replacement cycle, and during the water replenishment operation and the process of heating the water to the preset temperature value, it does not restrict the user's normal use, thereby improving the user experience.

[0043] In this embodiment, a filter element hot water regeneration method is provided, which can be used in the above-mentioned drinking water purification device with a filter element. Figure 2 is a flow chart of a filter element hot water regeneration method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0044] Step S201, obtaining the cumulative purified water volume of the filter element in the current drinking water purification device; judging whether the cumulative purified water volume of the filter element reaches the preset cycle purified water volume value.

[0045] The preset cycle net water volume value is the product of the preset single cycle net water volume and the cycle value.

[0046] The embodiment of the present invention can obtain the cumulative clean water volume Q of the filter element in the current drinking water purification device through methods such as the pump running time or flow meter in the drinking water purification device, and can determine whether the obtained cumulative clean water volume of the filter element reaches the preset cycle clean water volume value, that is, the preset hot water regeneration point of the filter element, wherein the preset cycle clean water volume value is represented by S=X*n, X represents the corresponding filter element clean water volume when the pre-carbon filter element undergoes a hot water regeneration cycle, and n represents the cycle value, that is, the number of hot water regeneration times, for example only.

[0047] Step S202, if the cumulative purified water volume of the filter element reaches the preset cycle purified water volume value, control the drinking water purification equipment to perform the water storage device water replenishment operation until the water volume of the water storage device is greater than the preset water volume threshold, and heat the water in the heating device to the preset temperature value.

[0048] The water in the heating device is the water in the water storage device flowing out to the heating device.

[0049] If the embodiment of the present invention determines that the current cumulative clean water volume of the filter element reaches the clean water volume value corresponding to a certain period, the pre-carbon filter element is controlled to enter the regeneration state, and the drinking water purification equipment can be controlled to execute the water storage device to perform a water replenishment operation until the water volume in the water storage device is greater than the preset water volume threshold. The water flowing out of the water storage device is heated to the preset temperature value by the heating device, and the subsequent filter element cleaning operation is performed.

[0050] The present invention obtains the cumulative water purification volume of the filter element of the drinking water purification equipment, and when the cumulative water purification volume of the filter element reaches a preset period water purification volume value, triggers the flushing operation of the filter element, thereby realizing the filter element flushing function fully automatically without the need for manual operation settings.

[0051] In an optional embodiment, the current operating time of the drinking water purification device is obtained; based on the operation time of performing the water storage device water replenishment operation and heating the water in the heating device to a preset temperature and the current operating time of the drinking water purification device, the operation completion time is determined; it is determined whether the operation completion time is within the preset filter element cleanable time period; if the operation completion time is within the preset filter element cleanable time period, the step of controlling the drinking water purification device to perform the water storage device water replenishment operation is executed.

[0052] After determining that the cumulative water purification volume of the filter element has reached the preset cycle water purification volume value, the embodiment of the present invention can determine that the hot water regeneration function needs to be started during the idle time of the day. Since the water purification device cannot start water production normally when executing the hot water regeneration function of the pre-carbon filter element, it will have a certain impact on the user experience. Therefore, in order to optimize the experience, a preset filter element cleanable time period can be set, wherein the filter element cleanable time period can be set by the user based on the actual use of the drink purification device, and can also be automatically collected and learned by the intelligent system. The general filter element cleanable time period can be a certain time period or an idle time point, such as the idle time from 1 am to 5 am, or the actual product application defaults to 2 am as the idle time point, as an example only.

[0053] The embodiment of the present invention can obtain the current operating time of the drinking water purification device, sum the current operating time of the drinking water purification device and the operation time T of currently executing the water storage device water replenishment operation and heating the water in the heating device to a preset temperature, and obtain the time after the water replenishment and heating operation is completed, and then it can be judged whether the time after the water replenishment and heating operation is completed is within the preset filter element cleanable time period or whether it reaches the preset idle time point. If it is within the preset filter element cleanable time period or reaches the preset display time point, the step of controlling the drinking water purification device to execute the water storage device water replenishment operation can be executed, wherein, the method for determining the operation time of currently executing the water storage device water replenishment operation and heating the water in the heating device to the preset temperature is to first obtain the water storage capacity and temperature of the current water storage device, and determine the corresponding operation time based on the water storage capacity and temperature. If it is determined that the current state of the drinking water purification device is a heat preservation state, the operation time is determined to be zero, that is, when the current operating time of the drinking water purification device reaches the preset idle time point, the operation of controlling the water in the water storage device to flush the filter element can be executed, which is only used as an example.

[0054] The present invention sets the filter element cleanable time period by combining usage scenarios and user experience. Only when the moment after the water replenishment and heating operation is completed is within the preset filter element cleanable time period, the water storage device will perform water replenishment and heating, and then the subsequent filter element flushing operation will be performed, thereby ensuring that the filter element flushing operation will not affect the user's normal use of the drinking water purification device, thereby improving the user experience.

[0055] Step S203, use the water heated to a preset temperature in the heating device to rinse the filter element, and drain the water after the rinsing operation. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0056] In some optional embodiments, it is monitored whether the user performs a water extraction operation on the drinking water purification device; if it is responded that the user performs a water extraction operation on the drinking water purification device, the flushing operation on the filter element is ended, and the process returns to the step of obtaining the current operating time of the drinking water purification device until the flushing operation on the filter element is completed.

[0057] During the filter cartridge flushing operation, the embodiment of the present invention can monitor in real time whether the user performs a water extraction operation on the drinking water purification device. If the user does not operate the drinking water purification device during the entire filter cartridge reoperation process, the filter cartridge flushing operation can be completed. If it is responded that the user performs a water extraction operation on the drinking water purification device, the current filter cartridge flushing operation can be ended, and the next filter cartridge cleanable time period identification can be entered. Generally, the filter cartridge hot water regeneration operation is started one day later, that is, the filter cartridge flushing operation is performed within the filter cartridge cleanable time period of the next day until the filter cartridge flushing operation is successfully completed.

[0058] The present invention monitors in real time whether the user is taking water during the filter element cleaning process. If it responds to the user performing the water taking operation, the flushing operation of the filter element is terminated to allow the user to take water normally and ensure the user's normal use. The filter element hot water regeneration operation can be started one day later to ensure the successful completion of the current filter element flushing operation.

[0059] In this embodiment, a filter element hot water regeneration method is provided, which can be used in the above-mentioned drinking water purification device with a filter element. Figure 3 is a flow chart of a filter element hot water regeneration method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0060] Step S301, control the water purifier to perform a water replenishment operation on the water storage device until the water volume in the water storage device exceeds a preset water volume threshold, and heat the water in the heating device to a preset temperature value. The water in the heating device is the water in the water storage device flowing out to the heating device. For detailed description, please refer to Figure 2 Step S201 and step S202 of the illustrated embodiment are not described in detail here.

[0061] Step S302, using water heated to a preset temperature in a heating device to flush the filter element, and draining the water after the flushing operation.

[0062] Step S303, start timing the cooling time of the filter element. After the cooling time of the filter element reaches a preset cooling time threshold, control the drinking water purification device to perform a water making operation, or allow the water in the water storage device to flow into the filter element to reduce the water temperature in the filter element.

[0063] Among them, the preset cooling time threshold is the cooling time when the filter element is cooled to the preset normal temperature.

[0064] After completing the flushing operation of the filter element in the embodiment of the present invention, the filter element cooling operation may be started, wherein the filter element cooling operation is not limited, for example, the filter element may be cooled by natural cooling or room temperature water replacement, etc., as an example only.

[0065] If the natural cooling method is used, the filter element cooling time can be started after the filter element flushing operation is completed. After the filter element cooling time reaches the preset cooling time threshold, the drinking water purification equipment can be controlled to perform the water making operation, wherein the preset cooling time threshold is the cooling time when the filter element is cooled to the preset normal temperature. As an example only, the method for judging whether the drinking water purification equipment has successfully completed the filter element flushing and cooling steps may be to obtain the water volume of the water storage device. Because before the filter element is flushed, the water storage device performs the water replenishment operation and the water volume is full, then after the cooling step, it can be determined whether the filter element flushing and cooling steps are successfully completed by judging whether the water volume of the water storage device is full. If it is full, it means that the filter element flushing operation has not been successfully completed. A prompt message can be sent to the user to enable the user to determine the cause of the problem and then repair the drinking water purification equipment. If the water volume of the water storage device is not full, it can be determined that the filter element flushing operation is successfully completed. As an example only.

[0066] If the method of replacing the filter element with normal temperature water is used to cool the filter element, after the flushing operation of the filter element is completed, the water replenishment operation can be performed in the water storage device until the water volume in the water storage device is greater than the preset water volume threshold, so that the normal temperature water in the water storage device flows into the filter element to replace the high temperature water in the filter element, and then water is made after cooling to prevent the hot water in the front carbon filter element from flowing into the rear end non-high temperature resistant components during normal water making, thereby affecting the life of the components. Among them, after the flushing and cooling of the filter element are completed, it is determined whether the water volume in the water storage device is full. If it is full, it is temporarily determined that the steps of flushing and cooling the filter element are completed normally. If it is not full, that is, it is less than the preset water volume threshold, it can be explained that the flushing and cooling steps are not running normally. A prompt message can be sent to the user to enable the user to determine the cause of the problem and then repair the drinking water purification equipment. As an example only, the cumulative net water volume of the front carbon filter element can continue to be calculated after the flushing and cooling of the filter element are completed.

[0067] The present invention performs a filter element cooling operation after completing the filter element flushing, thereby preventing hot water in the front carbon filter element from flowing into the rear end non-high temperature resistant components during normal water production.

[0068] In some optional embodiments, in response to the user's replacement operation of the filter cartridge in the drinking water purification device, the accumulated water purification volume of the filter cartridge in the current drinking water purification device is reset to zero.

[0069] In response to the user performing a replacement operation on the filter element in the drinking water purification device, the embodiment of the present invention can clean the accumulated purified water volume of the filter element in the drinking water purification device, reset n to 1, and restart the calculation of the purified water volume.

[0070] After responding to the user's operation of replacing the filter element in the drinking water purification device, the present invention resets the accumulated purified water volume of the filter element in the current drinking water purification device to zero, starts calculating the purified water volume of the replaced filter element, and ensures that the flushing operation of the filter element is performed on time.

[0071] In a specific embodiment, Figure 4 As shown, the preset idle time point of the drinking water purification device can be set according to the actual use needs of the user for the drinking water purification device, and the cumulative clean water volume of the pre-carbon filter element can be obtained in real time to determine whether the cumulative clean water volume of the pre-carbon filter element has reached the preset regeneration point, that is, the preset cycle clean water volume value.
