Summary of the Invention

[0003] In view of this, the present invention provides a water purification equipment flushing control method, device, water purification equipment and storage medium to solve the problem that the flow sensor is abnormal and cannot monitor the statistical changes of the water flow, resulting in the whole machine not performing flushing, accelerating the reverse osmosis filter element to be blocked and the water flow is rapidly attenuated, extending the user's quantitative water extraction time, shortening the core replacement cycle, increasing the user's usage cost, and affecting the user's daily use.

[0004] In a first aspect, the present invention provides a method for controlling flushing of a water purification device, the method comprising: obtaining a current water production flow rate of the water purification device collected by a flow collection device;

[0005] When it is determined that the current water flow rate is within a first preset flow rate range, the water purification device is controlled to perform abnormal flushing, and the number of abnormal flushing times currently recorded is increased, and it is determined whether the increased number of abnormal flushing times is greater than a preset number threshold, wherein the first preset flow rate range represents a flow rate range corresponding to when the water flow of the water purification device is abnormal;

While being able to bring more accurate water production volume calculation, it also improves the system fault tolerance, avoids the failure of the entire machine function due to the failure of key materials, and affects the user experience.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying 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 making creative efforts shall fall within the scope of protection of the present invention.

[0034] For water purifiers that rely on flow sensors to calculate water production, during the normal ice-making process, the Hall sensor on the PCB board inside the water flow sensor and the magnetic rotor assembly need to meet specific sensing distance requirements. When the PCB board assembly of the flow meter sensor is floating (that is, the sensing distance becomes larger) or the magnetization of the magnetic rotor is too low, the Hall sensor cannot monitor the rotation speed of the magnetic rotor assembly. As a result, the pulse signal detected by the MCU is lower than the set value or is 0, and the number of liters of water produced is not calculated. As a result, the entire machine will not be flushed, which will accelerate the clogging of the reverse osmosis filter element, rapidly decay the purified water flow, extend the user's quantitative water extraction time, shorten the filter element replacement cycle, increase the user's usage cost, and affect the user's daily use.

[0035] The basic water system for water purifiers that rely on flowmeters to calculate flow rate consists of the following key components: a composite filter element, an inlet solenoid valve, a booster pump, a flow sensor, an RO filter element, a wastewater valve, a post-composite filter element, and finally a water tap. Under the existing water system configuration, the present invention determines the water flow rate and flushing logic based on the liters of water flowing through the flow sensor. After a certain number of liters of water have been produced cumulatively or continuously, the RO filter element must be flushed. Otherwise, the RO filter element is susceptible to fouling and clogging, causing a rapid decrease in the water flow rate.

[0036] The present invention collects and detects the rotation speed of the flow sensor under normal water production conditions of the whole machine, compares and judges with the normal flow rate threshold, and then determines whether the rotation of the flow sensor is abnormal. Under abnormal circumstances, the water flow calculation method of the water purifier is switched, and the running time of the booster pump in the water production state is used to convert the water flow, thereby avoiding problems such as filter element blockage caused by inaccurate flow statistics of the whole machine due to abnormal calculation of the flow sensor, and realizing accurate calculation of the water production of the filter element, thereby increasing user usage time and reducing the cost of replacing the filter element.

[0037] According to an embodiment of the present invention, an embodiment of a water purification equipment flushing control 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.

[0038] In this embodiment, a water purification equipment flushing control method is provided, which can be used for the above-mentioned water purification equipment. Figure 1 Flowchart of a water purification equipment flushing control method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0039] Step S101: obtaining the current water production flow rate of the water purification equipment collected by the flow collection device.

[0040] The embodiment of the present invention does not limit the type of flow collection device, which can be installed on the water purification equipment to collect the water flow rate, such as a flow sensor. After the water purification equipment is powered on and the user turns on the faucet, the entire machine starts to produce water, and the flow collection device, that is, the flow sensor, starts to collect the number of pulses, which represents the water flow rate of the water purification equipment.

[0041] Step S102, when it is determined that the current water flow rate is within the first preset flow rate range, the water purification equipment is controlled to perform abnormal flushing, and the currently recorded abnormal flushing times are increased, and it is determined whether the increased abnormal flushing times are greater than the preset times threshold.

[0042] The first preset flow rate range indicates the flow rate range corresponding to abnormal water flow in the water purification equipment.

[0043] The water flow rate of the water purification equipment in the embodiment of the present invention is mainly affected by three factors, including but not limited to water shortage and flow interruption (if water shortage and flow interruption abnormality occurs, the water flow rate of the corresponding water purification equipment will be very small); the filter element of the water purification equipment is clogged, the flow rate is small, resulting in a low speed; the flow sensor sensing distance is abnormal, resulting in the speed fed back to the sensor being less than the actual speed. Therefore, the flow rate range corresponding to the water flow abnormality of the water purification equipment can be set, which can be expressed by [R0, R1], as an example only.

[0044] In the embodiment of the present invention, when it is determined that the current water production flow rate collected by the current flow collection device is within the flow rate range corresponding to the water flow abnormality in the set water purification equipment, it can indicate that there is a problem in the water production of the current water purification equipment, but the specific abnormal factor cannot be determined. The water purification equipment can be controlled to perform abnormal flushing, and the abnormal flushing can be performed for a certain period of time. After completing the flushing for a certain period of time, the water purification equipment can be switched back to the water production state, and the flow collection device can be controlled to re-collect the water production flow rate. At the same time, the number of abnormal flushing times recorded currently can be increased, generally by accumulating the number of abnormal flushing times recorded currently under the condition of low rotation speed. For example only, it can be determined whether the abnormal flushing data after the increase is greater than the preset number threshold, wherein the preset number threshold The setting is not limited and can be set according to actual needs. It can be represented by Ntemp. As an example only, after the abnormal flushing is performed in the embodiment of the present invention, it is determined whether the number of consecutive abnormal flushing is greater than the number threshold. If after the abnormal flushing, the number of consecutive abnormal flushing is less than the preset number threshold and the water flow rate of the water purification equipment is detected to be within the normal flow rate after the abnormal flushing, it means that the factor for the low water flow rate is filter element congestion. After the corresponding abnormal flushing is performed, the problem of filter element congestion can be solved. If the number of consecutive abnormal flushing is greater than the preset number threshold, it means that the reason for the low water flow rate is an abnormality in the flow collection device, which can avoid the misjudgment of the flow sensor abnormality due to the low water flow rate caused by filter element congestion.

[0045] In step S103, if the increased number of abnormal flushing times is greater than the preset number threshold, the flow collection device is determined to be abnormal, and the running time of the booster pump in the water purification equipment is started. When the running time of the booster pump reaches the preset time, the water purification equipment is controlled to flush.

[0046] The embodiment of the present invention is based on the judgment that the increased number of abnormal flushing times is greater than the preset number threshold, indicating that the reason for the low water flow speed is that there is an abnormality in the flow collection. The water flow rate can be calculated by the running time of the booster pump installed on the water purification equipment. The running time of the booster pump in the water purification equipment is started to be counted, and the water flow rate of the whole machine is counted by the running time of the booster pump. When it is detected that the cumulative running time or the continuous running time of the whole machine reaches the preset time T1 set by the system, the water purification equipment is controlled to be flushed. This flushing is generally a normal flushing operation, which is only used as an example and is not limited.

[0047] In an optional embodiment, the embodiment of the present invention may further install a backup flow sensor in the water purification equipment. After determining that the flow collection device is abnormal, the backup flow sensor is controlled to detect the water production flow rate, which is only an example.

[0048] The water purification equipment flushing control method provided by the present invention can determine that the flow acquisition device is abnormal by judging the flow rate range corresponding to the water flow abnormality in the water purification equipment, and the number of abnormal flushing is greater than the preset threshold number. In the case of an abnormal flow sensor, it can timely switch to calculating the number of liters of water flowing through the water purification equipment by the running time of the booster pump. While being able to bring more accurate water production volume calculation, it also improves the system fault tolerance, avoids the failure of the entire machine function due to the failure of key materials, and affects the user experience.

[0049] In this embodiment, a water purification equipment flushing control method is provided, which can be used for the above-mentioned water purification equipment. Figure 2 Flowchart of a water purification equipment flushing control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0050] Step S201: Obtain the current water flow rate of the water purification equipment collected by the flow collection device. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0051] Step S202, when it is determined that the current water production flow rate is within the first preset flow rate range, the water purification equipment is controlled to perform abnormal flushing, and the number of abnormal flushing times currently recorded is increased, and it is determined whether the increased number of abnormal flushing times is greater than the preset number threshold, wherein the first preset flow rate range represents the flow rate range corresponding to the water flow abnormality of the water purification equipment.

[0052] Specifically, the above step S202 includes:

[0053] Step S2021, controlling the water purification equipment to perform abnormal flushing, and starting to count the abnormal flushing time of the water purification equipment.

[0054] Step S2022: After the current abnormal flushing duration reaches a preset abnormal flushing duration threshold, the abnormal flushing of the water purification equipment is stopped.

[0055] The preset abnormal flushing time threshold is greater than the normal flushing time.

[0056] When the embodiment of the present invention determines that the water flow rate is within the flow rate range corresponding to the water flow abnormality in the water purification equipment, it may indicate that the filter element of the water purification equipment may be clogged or the flow sensor is abnormal. Therefore, it can be assumed that the water flow rate of the water purification equipment is low due to the clogged filter element, and the water purification equipment is controlled to perform abnormal flushing. Generally, in order to solve the low flow rate caused by reasons such as filter clogs, the abnormal flushing time threshold is greater than the normal flushing time. For example, under normal water flow rate, a flushing time of 30s can ensure that the filter element is in normal operating conditions. However, when the water flow rate is within the first preset flow rate range, the flushing time will be longer. For example, a flushing time of 60s may solve the problem of filter clogs. This is just an example.

[0057] When the embodiment of the present invention determines that the current water production flow rate is within the first preset flow rate range, it controls the water purification equipment to perform abnormal flushing, and can start timing the abnormal flushing time of the water purification equipment. After the current abnormal flushing duration reaches the preset abnormal flushing duration threshold, the abnormal flushing of the water purification equipment can be stopped, and the water purification equipment can be switched back to the water production state to re-collect the water production flow rate.

[0058] When determining that the water flow rate is low, the present invention can control the water purification equipment to perform abnormal flushing for a longer time to determine whether the low water flow rate is caused by filter blockage, and can accurately and timely judge the cause of the low water flow rate.

[0059] In some optional embodiments, when it is determined that the current water production flow rate is within the second preset flow rate range, the number of liters of water passing through the water purification equipment is counted through a flow sensor, and after the number of liters of water passing through the water purification equipment reaches the set liter threshold, the water purification equipment is controlled to perform normal flushing. The second preset flow rate range represents the flow rate range corresponding to when the water flow of the water purification equipment is normal, and the minimum flow rate value within the second preset flow rate range is not less than the maximum flow rate value within the first preset flow rate range; the currently recorded number of abnormal flushing times is cleared.

[0060] In the embodiment of the present invention, when determining the current water flow rate within the flow rate range corresponding to the normal water flow of the water purification equipment, the normal flow rate range can be represented by [R1, R2]. The minimum flow rate value within the second preset flow rate range is not less than the maximum flow rate value within the first preset flow rate range, and they are generally equal. For example only, the whole machine uses the flow sensor pulse number to count the number of liters of water flowing through. After calculating that the number of liters of water flowing through the water purification equipment reaches the set liter threshold, the water purification equipment can be controlled to perform normal flushing. At this time, regardless of whether the water flow rate re-collected after the abnormal flushing is within the normal flow rate range, or the water flow rate detected at the beginning is within the normal flow rate range, or other situations, the currently recorded number of abnormal flushes can be cleared. When the flow rate is within the normal flow rate range [R1, R2] at any time during the detection process, the cumulative number of flushes with a lower speed N is immediately cleared. When the speed is lower next time, the number of flushes will be accumulated again. For example only.

[0061] When the present invention determines that the water flow rate is within the normal flow rate range, it controls the water purification equipment to perform normal flushing, and the currently recorded abnormal flushing times can be cleared to ensure that the cause of the abnormality is determined in a timely and accurate manner when the water purification flow rate is lower next time.

[0062] In some optional implementations, when it is determined that the current water production flow rate is less than the third preset flow rate threshold, it is determined that there is a water shortage abnormality in the water purification equipment, and the currently recorded abnormal flushing times are cleared.

[0063] The third preset flow rate threshold is not greater than the minimum value within the second preset flow rate range.

[0064] The third preset flow rate threshold of the embodiment of the present invention is not greater than the minimum value of the second preset flow rate range. Generally, the third preset flow rate threshold is equal to the minimum value of the second preset flow rate range. If it is determined that the current water production flow rate is less than the third preset flow rate threshold, it can be determined that the water production equipment is short of water and the flow is interrupted. The user can first perform maintenance on the water production equipment. For example, the faucet is not turned on, and the water production flow rate is normal after the faucet is turned on. This is just an example. At this time, the currently recorded number of abnormal flushing times can be cleared.

[0065] The present invention divides the water production flow rate into multiple situations, and handles different situations accordingly, and can specifically determine whether the flow sensor is abnormal. If the flow sensor is abnormal, it is ensured that the flow rate water flow calculation method can be switched in time.

[0066] Step S203: If the increased abnormal flushing times are greater than the preset times threshold, the flow acquisition device is determined to be abnormal, and the running time of the booster pump in the water purification equipment is started. When the running time of the booster pump reaches the preset time, the water purification equipment is controlled to flush. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0067] Step S204: clear the currently recorded number of abnormal flushing times.

[0068] In the embodiment of the present invention, after determining that the current booster pump operation time reaches a preset time, the water purification device can be controlled to perform flushing. After the flushing is completed, the currently recorded number of abnormal flushing times can be cleared.

[0069] In some optional implementations, after determining that the flow collection device is abnormal, a prompt message indicating that the flow collection device is abnormal is sent to the user.

[0070] In the embodiment of the present invention, after determining that the flow collection device is abnormal, the entire device can report the flow sensor abnormality display code and can automatically push the abnormality remotely to the user end and the after-sales service end.

[0071] After determining that the flow collection device is abnormal, the present invention can prompt the user with the abnormal information of the flow collection device, so that the user can repair the flow collection device in time to avoid the failure of the entire machine due to the failure of key materials, which affects the user experience.

[0072] In some optional implementations, the service life of the water purification device is determined based on the number of pulses collected by the flow collection device and the operating time of the booster pump.

[0073] The number of pulses collected by the flow collection device represents the water flow rate of the water purification equipment.

[0074] The filtering effect of the water purification equipment of the embodiment of the present invention depends on the filter element. As the water consumption increases, the filtering performance of the filter element will decline. When the performance indicators of the filter element such as the water outlet flow rate and desalination rate cannot meet the national standards, the filter element is considered to have expired. During the life cycle, the filter element decay can be slowed down by regularly flushing the surface of the filter element by counting a certain number of liters of water flowing through or counting the water production time of the entire machine. The water consumption and flushing entry conditions need to be collected and converted by any of the above two methods. If only the flow sensor is used for calculation, the number of liters of water flowing through cannot be detected when it is abnormal, which in turn affects the normal flushing of the entire machine, accelerates the attenuation of the filter element performance, and affects the service life of the entire machine. Therefore, when using the flow acquisition device to collect the number of pulses, the service life of the water purification equipment is calculated by the number of pulses of the flow sensor. When the number of liters of water flowing through is calculated by the running time of the booster pump, the service life of the water purification equipment is continued to be calculated by the running time of the booster pump.

[0075] Under normal circumstances, the whole machine of the embodiment of the present invention uses a flow meter for statistics. The flow meter statistics of the number of liters of water passing through are more accurate than time estimation. Therefore, the flow meter is used to calculate the number of liters of water passing through the filter element first. Only when the flow meter is abnormal, the operating time of the pressure-stabilizing pump under water production conditions is used to accumulate the number of liters of water passing through.

[0076] The present invention calculates the service life of the water purification equipment based on a calculation method of the number of liters of water currently used, and can accurately calculate the service life of the water purification equipment, making subsequent maintenance convenient.
