Description

Technical Field

[0001] The present application relates to the field of software control technology, and in particular to a regeneration control method and device for a water softener. Background Art

[0002] At present, with the improvement of people's living standards, various water softener products have emerged on the market. Water softeners use ion exchange resins to absorb calcium and magnesium ions in water to soften water and reduce scale. When the exchange capacity of the exchange resin is saturated, it is necessary to backwash the softening resin with brine to exchange the calcium and magnesium ions adsorbed on the resin with sodium ions, so that the resin can regain the ability to soften water.

[0003] However, how to ensure that the resin can be regenerated in time when it is saturated or close to saturation is a very critical issue. At present, traditional water softeners adjust the regeneration time by calculating the user's water consumption (flow regeneration), the maximum number of days between regenerations, and the amount of water that can be adjusted according to the number of people. The above methods may have the following disadvantages:

[0004] (1) The calculation is based on the user's water consumption, which is calculated based on the flow meter of the water softener. However, the flow meter may be at risk of attenuation and failure after long-term use.

[0005] (2) Adjusting according to the maximum regeneration interval and the number of people is not very accurate and will affect the user's water experience. Summary of the invention

[0006] In response to the above-mentioned problems, the present application provides a water softener regeneration control scheme, which adds a periodic self-learning regeneration interval regeneration based on the user's water usage habits on the basis of traditional flow regeneration and maximum regeneration interval regeneration. It can automatically determine the appropriate regeneration interval days in traditional flow regeneration, maximum regeneration interval regeneration and self-learning regeneration interval regeneration according to the error of the water softener flow meter.

[0010] Determining the regeneration interval of the water softener according to the self-learning regeneration interval and the flow regeneration interval; and

[0011] When the regeneration interval of the water softener is reached, the regeneration process of the water softener is started.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] Figure 1 Schematic diagram of the structure of a water softener according to an embodiment of the present application. Figure 1As shown, the water softener includes a control valve assembly, a resin tank assembly, a salt box system, a flow meter, an operation display module, etc. The control valve assembly has a main control board, a flow detection module and a water circuit switching module. The control valve assembly can switch the water circuit through flow triggering, time setting and manual operation under program setting conditions. The switching water circuit described in the present invention is that when the water softener is in normal water production and regeneration, the water circuit system in the machine needs to be changed to meet the functional requirements. The resin tank assembly is a tank body that holds the regenerated resin. The direction of water flow in the tank body is opposite during regeneration and water production. The flow meter is located at the water inlet end or the water outlet end, and is used to measure the flow of water. The operation display module is an operation display interface that interacts with people, and users can input parameters and observe the operating status of the machine. The salt box system is a barrel assembly that provides regenerated brine to the resin.

[0034] In an embodiment of the present application, a regeneration control program is run in the control valve assembly, and the regeneration interval days are obtained by grabbing the flow measured by the flow meter and self-learning based on the periodic water usage habits of the user, and the error rate of the flow meter is taken into consideration. The regeneration interval days of the water softener are determined based on the self-learning regeneration interval days and the flow regeneration interval days or the self-learning regeneration interval days and the preset maximum regeneration interval days. When the regeneration interval days of the water softener are reached, the regeneration process of the water softener is started.

[0035] For regenerative control schemes operating in control valve assemblies, the Figure 2 The illustrated embodiments are described in detail.

[0036] According to one aspect of the present application, a regeneration control method for a water softener is provided. Figure 2 Flowchart of the regeneration control method of the water softener according to the embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0037] Step S201, calculating the number of days between self-learning and regeneration according to the flow rate measured by the flow meter of the water softener within a predetermined time period;

[0038] Step S202, when the error rate of the flow meter is less than a preset value, determining the flow regeneration interval days according to the flow currently measured by the flow meter, and determining the regeneration interval days of the water softener according to the self-learning regeneration interval days and the flow regeneration interval days; and

[0039] Step S203, when the regeneration interval of the water softener is reached, starting the regeneration process of the water softener.

[0040] Since the self-learning regeneration interval is determined based on the flow rate measured by the flow meter of the water softener, according to some embodiments, it is necessary to first determine the time to ensure the reliable accuracy of the flow meter. During the reliable accuracy time of the flow meter, the regeneration interval is continuously determined and adjusted by the flow rate measured by the meter; outside the reliable accuracy time of the flow meter, the regeneration interval is determined based on the regeneration interval obtained during the reliable accuracy period.

[0041] According to a specific embodiment, the time when the accuracy of the flow meter is reliable is one year (corresponding to the preset regeneration learning time), and 21 consecutive days in one year are a period (corresponding to the first preset time period). The flow measured by the flow meter in the consecutive 21 days is determined and the average daily flow (daily water consumption) is determined. Then, the regeneration interval days are calculated according to the expected water production (corresponding to the first self-learning regeneration interval days). Subsequently, the average daily water consumption in the previous 21 days is calculated once a day (that is, the flow measured by the flow meter of the water softener from the current time to the first preset time period is calculated), and the regeneration interval days are calculated and adjusted. In this way, the machine is allowed to learn for one year (corresponding to the preset regeneration learning time). During the time when the accuracy of the flow meter is reliable, the regeneration interval days of the water softener are determined by the first self-learning regeneration interval days and the flow regeneration interval days.

[0042] According to a specific embodiment, outside the time when the accuracy of the flow meter is reliable, when it reaches one year, the flow meter of the water softener measures the flow rate for half a year (corresponding to the second preset time period) and determines the average daily flow rate (daily water consumption), and then calculates the regeneration interval days (corresponding to the second self-learning regeneration interval days) according to the expected water production. Among them, the second preset time period is any time period within the preset regeneration learning time, and the length can be arbitrary, usually greater than the first preset time period. For example, on the 365th day (corresponding to the day when the preset regeneration learning time is reached), trace back the flow rate measured by the flow meter of the water softener for half a year (corresponding to the second preset time period) and determine the average daily flow rate (daily water consumption), and then calculate the regeneration interval days (corresponding to the second self-learning regeneration interval days) according to the expected water production. When selecting the second preset time period, you can choose a period of time later in the preset regeneration learning time, because this period is closer to the user's current water use habits. Outside the time when the accuracy of the flow meter is reliable, the regeneration interval days of the water softener are determined by the second self-learning regeneration interval days and the flow regeneration interval days.

[0043] Thus, step S201 may include:

[0044] Within the preset regeneration learning time, calculating the first self-learning regeneration interval days according to the flow rate measured by the flow meter of the water softener currently traced back to the first preset time period; and

[0045] When the preset regeneration learning time is reached, the second self-learning regeneration interval days are calculated according to the flow rate measured by the flow meter of the water softener within a second preset time period, wherein the second preset time period is longer than the first preset time period.

[0046] Step S202 may include:

[0047] Determining the regeneration interval of the water softener according to the first self-learning regeneration interval and the flow rate regeneration interval within the preset regeneration learning time;

[0048] When the preset regeneration learning time is reached, the regeneration interval days of the water softener are determined according to the second self-learning regeneration interval days and the flow regeneration interval days.

[0049] In the above embodiment, when the preset regeneration learning time is reached, learning is no longer performed based on the flow rate measured by the flow meter. According to other embodiments, when the preset regeneration learning time is reached, learning can also continue based on the flow rate measured by the flow meter.

[0050] According to a specific embodiment, within the preset regeneration learning time (such as one year), multiple preset time periods (corresponding to the third preset time period), such as 60 days, are determined, and the flow rate measured by the flow meter of the water softener within 60 days is counted and the average daily flow rate (daily water consumption) is determined. Then, the regeneration interval days (corresponding to the third self-learning regeneration interval days) are calculated according to the expected water production, so that multiple third self-learning regeneration interval days can be obtained. The smallest interval days among these multiple third self-learning regeneration interval days are determined as the alternative interval days. Then, when the preset regeneration learning time is reached, the average daily flow rate (daily water consumption) is determined based on the flow rate measured by the flow meter of the water softener within 60 days (corresponding to the third preset time period) from the current, and the regeneration interval days are calculated according to the expected water production (corresponding to the current third self-learning regeneration interval days). Finally, the interval days with the smallest value between the alternative interval days and the current third self-learning regeneration interval days are determined as the self-learning regeneration interval days. In this way, within the preset regeneration learning time, the self-learning regeneration interval days obtained within the preset regeneration learning time participate in determining the regeneration interval days of the water softener; after the preset regeneration learning time expires, the self-learning regeneration interval days obtained after the expiration participate in determining the regeneration interval days of the water softener.

[0051] Thus, step S201 may further include:

[0052] During the preset regeneration learning time, a plurality of third self-learning regeneration interval days are calculated accordingly according to the flow rate measured by the flow meter of the water softener within a plurality of third preset time periods;

[0053] Determine the smallest interval number of days among the plurality of three-self-learning regeneration interval numbers of days as the candidate interval number of days;

[0054] When the preset regeneration learning time is reached, calculating the current third self-learning regeneration interval days according to the flow rate measured by the flow meter of the water softener from the current traceback to the third preset time period; and

[0055] The interval number with the smallest value between the alternative interval number of days and the current third self-learning regeneration interval number of days is determined as the self-learning regeneration interval number of days.

[0056] In the above embodiment, the situation of not learning according to the flow rate measured by the flow meter and continuing to learn according to the flow rate measured by the flow meter when the preset regeneration learning time is reached is described. According to other embodiments, regardless of whether the preset regeneration learning time is reached, the regeneration interval days are continuously learned in multiple preset time periods, and when a new regeneration interval days is obtained, the new regeneration interval days are compared with the previously obtained regeneration interval days, and the minimum regeneration interval days are determined as the self-learning regeneration interval days.

[0057] According to a specific embodiment, the preset time period is 60 days (corresponding to the fourth preset time period). As the water softener starts to run, there are one or more fourth preset time periods. For each fourth preset time period, the flow rate measured by the flow meter of the water softener within 60 days can be counted and the average daily flow rate (daily water consumption) can be determined. Then, the regeneration interval days (corresponding to the fourth self-learning regeneration interval days) are calculated according to the expected water production. In this way, a fourth self-learning regeneration interval days can be determined for each fourth preset time period, and one or more fourth self-learning regeneration interval days can be obtained. Next, based on the flow rate measured by the flow meter of the water softener within 60 days from the current traceback and the average daily flow rate (daily water consumption), the regeneration interval days (corresponding to the current fourth self-learning regeneration interval days) are calculated according to the expected water production. Finally, the interval days with the smallest value between one or more fourth self-learning regeneration interval days and the current fourth self-learning regeneration interval days are determined as the self-learning regeneration interval days. In this way, the self-learning regeneration interval days are continuously updated and determined, and the latest updated self-learning regeneration interval days are involved in determining the regeneration interval days of the water softener.

[0058] Thus, step S201 may include:

[0059] Calculate the current fourth self-learning regeneration interval days according to the flow rate measured by the flow meter of the water softener from the current time to the fourth preset time period;

[0060] When there are one or more fourth self-learning regeneration interval days corresponding to the fourth preset time period, the interval with the smallest value between the one or more fourth self-learning regeneration interval days and the current fourth self-learning regeneration interval days is determined as the self-learning regeneration interval days.

[0061] It can be understood that in the above embodiment, the lengths of the preset time periods, including the first preset time period, the second preset time period, the third preset time period and the fourth preset time period, can be set arbitrarily, and the preset time periods can be isolated or overlapped.

[0062] The water softener has a flow calculation module, which can calculate in real time the total actual water consumption L1 of the machine when the new machine is used or since the last regeneration; the water softener has an estimated water production L0 based on the hardness of the user's raw water, and flow regeneration is to determine whether the machine is regenerated by determining whether the actual water consumption L1 reaches the estimated water production L0 set by the program. According to some embodiments, in the process of determining the number of days between flow regeneration based on the flow currently measured by the flow meter, the basis is the estimated water production, that is, whether the flow currently measured by the flow meter reaches the estimated water production. If it does not reach the estimated water production, then in terms of flow regeneration, the regeneration conditions have not been met. For example, since the last regeneration, the water softener has been producing water for 7 days. If the flow currently measured by the flow meter does not reach the estimated water production, it means that the number of days between flow regeneration is greater than 7 days; if the flow currently measured by the flow meter reaches the estimated water production, it means that the number of days between flow regeneration is 7 days.

[0063] According to some embodiments, the preset maximum regeneration interval is the number of days for regeneration isolation to ensure the normal operation of the water softener. The reasons for setting the maximum regeneration interval include: (1) the user does not use the water softener for a long time, and the resin inside the machine is prone to bacteria growth and yellow water, and needs to be regenerated and flushed regularly; (2) the resin of the machine is not regenerated for a long time, and the resin performance will decline, and regular regeneration is required to activate the resin. According to a specific embodiment, the preset maximum regeneration interval can be 14 days.

[0064] Regarding how to determine the regeneration interval of a water softener based on the flow regeneration interval, the preset maximum regeneration interval and the self-learning regeneration interval, the present application takes into account the error rate of the flow meter and sets a preset value, such as 20%, 25%, etc. When the error rate of the flow meter is less than the preset value, the flow regeneration interval is determined based on the flow currently measured by the flow meter, and then the regeneration interval of the water softener is determined based on the self-learning regeneration interval and the flow regeneration interval.

[0065] The error rate of the flow meter and the reliable time of the flow meter accuracy are different ways of evaluating the performance of the flow meter from different aspects. The reliable time of the flow meter accuracy, such as one year, is the reliable time of the flow meter accuracy determined based on experience, while the error rate of the flow meter is determined by measurement and calculation. According to some embodiments, the error rate of the flow meter is calculated and determined during the regeneration process of the water softener. The error rate determined during this regeneration process will be used as a basis for determining whether to include the flow regeneration in the next regeneration interval of the water softener. For determining the first regeneration interval, the error rate of the flow meter can be set to 0% or set to an error less than a preset value.

[0066] According to some embodiments, when the error rate of the flow meter is less than a preset value, after determining the self-learning regeneration interval and the flow regeneration interval, the interval with the smallest value between the two is determined as the regeneration interval of the water softener, and when the regeneration interval of the water softener is reached, the regeneration process of the water softener is started.

[0067] Figure 3 is a flow chart of a regeneration control method for a water softener according to another embodiment of the present application. Figure 2 compared to, Figure 3 Steps S301 to S303 and Figure 2 The steps S201 to S203 are the same as above, except that: Figure 3 The method shown also includes:

[0068] Step S304, when the error rate is not less than the preset value, determining the regeneration interval of the water softener according to the self-learning regeneration interval and the preset maximum regeneration interval.

[0069] According to some embodiments, when the error rate of the flow meter is not less than a preset value, the regeneration interval of the water softener is determined according to the self-learning regeneration interval and the preset maximum regeneration interval. When the error rate of the flow meter is not less than a preset value, after determining the self-learning regeneration interval and the preset maximum regeneration interval, the interval with the smallest value between the two is determined as the regeneration interval of the water softener, and when the regeneration interval of the water softener is reached, the regeneration process of the water softener is started.

[0070] Step S304 may include:

[0071] Determining the regeneration interval of the water softener according to the first self-learning regeneration interval and the preset maximum regeneration interval within the preset regeneration learning time;

[0072] When the preset regeneration learning time is reached, the regeneration interval days of the water softener are determined according to the second self-learning regeneration interval days and the preset maximum regeneration interval days.

[0073] Figure 4 FIG. 1 is a flow chart of a regeneration control method for a water softener according to another embodiment of the present application. Figure 2 compared to, Figure 4 Steps S401 to S403 are Figure 2 The steps S201 to S203 are the same, except that: Figure 4 The method shown also includes:

[0074] Step S404, during the process of starting the regeneration process of the water softener, calculating the current error rate of the flow meter.

[0075] According to some embodiments, the flowmeter can be located at the water inlet of the water softener. During the regeneration process of the water softener, the water path of the water softener is: water inlet → flowmeter → control valve assembly → resin tank → control valve assembly → wastewater outlet. Since the control valve assembly has a flow limiting module, and the water softener program has corresponding wastewater flow rates for different water pressures (for example, different water pressures have corresponding wastewater flow rates per unit time), the wastewater flow rate during regeneration can be obtained. Moreover, for the salt absorption from the salt tank, different water pressures also have corresponding flow rates. At the same time, the water softener program can capture the flowmeter flow, compare the captured flowmeter flow Q with the difference between the wastewater flow Q1 and the salt absorption Q2, for example, it can be [Q-(Q1-Q2)] / (Q1-Q2), and the error rate of the flowmeter can be calculated.

[0076] According to other embodiments, the flowmeter may also be located at the water outlet of the water softener. According to a specific embodiment, an electrically controlled switch valve may be added between the rear end of the flowmeter at the water outlet of the water softener and the wastewater outlet. The switch valve is closed by default, and when the machine needs to be regenerated, the switch valve is opened. When the water softener needs to be regenerated, the switch valve is opened, and the flow through the flowmeter is the wastewater flow Q. The water softener program has corresponding wastewater flows for different water pressures, so that the wastewater flow Q1 during regeneration can be obtained. The captured flowmeter flow Q is compared with the wastewater flow Q1, for example, it can be (Q-Q1) / Q1, and the error rate of the flowmeter can be calculated.

[0077] Thus, step S404 may include:

[0078] When the flow meter is located at the water inlet of the water softener, the current error rate of the flow meter is calculated according to the flow detected by the flow meter, the flow of the wastewater outlet of the water softener and the salt absorption amount corresponding to the salt tank; and

[0079] In the case where the flow meter is located at the water outlet of the water softener, the current error rate of the flow meter is calculated according to the flow detected by the flow meter and the flow at the wastewater outlet of the water softener.

[0080] According to some embodiments, when it is detected that the error rate of the flow meter exceeds a preset value, an alarm message may be issued, such as emitting an alarm sound or displaying an alarm message on the operation display module of the water softener, or notifying R&D and after-sales service for processing.

[0081] Based on the above-mentioned regeneration control method of a water softener, according to another aspect of the present application, a regeneration control device of a water softener is provided. Figure 5 Schematic diagram of a regeneration control device for a water softener according to an embodiment of the present application. Figure 5 As shown, the device includes a first calculation module 501, a first determination module 502 and a regeneration processing module 503. The first calculation module 501 is used to calculate the self-learning regeneration interval days according to the flow rate measured by the flow meter of the water softener within a predetermined time period; the first determination module 502 is used to determine the flow regeneration interval days according to the flow currently measured by the flow meter when the error rate of the flow meter is less than a preset value, and determine the regeneration interval days of the water softener according to the self-learning regeneration interval days and the flow regeneration interval days; the regeneration processing module 503 is used to start the regeneration processing of the water softener when the regeneration interval days of the water softener are reached.

[0082] According to some optional embodiments, the first calculation module 501 may be used to:

[0084] When the preset regeneration learning time is reached, the second self-learning regeneration interval days are calculated according to the flow rate measured by the flow meter of the water softener within a second preset time period, wherein the second preset time period is longer than the first preset time period.

[0085] The first determination module 502 may be used to:

[0086] Determining the regeneration interval of the water softener according to the first self-learning regeneration interval and the flow rate regeneration interval within the preset regeneration learning time;

[0087] When the preset regeneration learning time is reached, the regeneration interval days of the water softener are determined according to the second self-learning regeneration interval days and the flow regeneration interval days.

[0088] According to some optional embodiments, the first calculation module 501 may also be used for:

[0089] During the preset regeneration learning time, a plurality of third self-learning regeneration interval days are calculated accordingly according to the flow rate measured by the flow meter of the water softener within a plurality of third preset time periods;

[0092] The interval number with the smallest value between the alternative interval number of days and the current third self-learning regeneration interval number of days is determined as the self-learning regeneration interval number of days.

[0093] According to some optional embodiments, the first calculation module 501 may also be used for:

[0094] Calculate the current fourth self-learning regeneration interval days according to the flow rate measured by the flow meter of the water softener from the current time to the fourth preset time period;

[0095] When there are one or more fourth self-learning regeneration interval days corresponding to the fourth preset time period, the interval with the smallest value between the one or more fourth self-learning regeneration interval days and the current fourth self-learning regeneration interval days is determined as the self-learning regeneration interval days.

Figure 5 compared to, Figure 6 Modules 601 to 603 and Figure 5 Modules 501 to 503 are the same except that: Figure 6 The device shown also includes:

In this way, on the one hand, the regeneration interval can be adjusted according to the user's water use habits, so that the regeneration interval is more in line with actual needs, and on the other hand, the problem of failure to regenerate in time due to failure of the flow meter after long-term use can be avoided.
