Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment control, and in particular to a method, device, equipment, storage medium and program product for identifying the life of a filter element. Background Art

[0002] As people's living standards are getting higher and higher, the requirements for drinking water are also getting higher and higher. Water purifiers have become one of the basic appliances in people's homes. The filter element is the core material for purifying water quality, and it needs to be replaced on time to ensure excellent filtering effects. The life of the filter element is generally determined by a flow meter to detect the flow rate flowing through the filter element or the water production time. The former will not report the filter element life when the flow meter is damaged. The latter water production time judgment leaves a large margin when setting parameters for the sake of insurance, which may cause waste in places with good water quality. The above two judgment methods will lead to inaccurate identification of the filter element life, and when the user's water consumption is small or not used for a long time, the filter element expiration condition may not be met for a long time. Not prompting to change the element for too long will cause confusion to the user and affect the user experience. Summary of the invention

[0003] In view of this, the present invention provides a method, device, equipment, storage medium and program product for identifying the life of a filter element to solve the problem of inaccurate identification of the life of a filter element.

[0004] In a first aspect, the present invention provides a method for identifying the life of a filter element, the method comprising:

[0005] During the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element;

[0006] Check whether the flow meter is abnormal;

[0007] If the flow meter does not show any abnormality, the filter element life is determined based on the water flow rate and the power-on time of the whole machine.

[0008] If the flow meter is abnormal, the filter element life will be determined based on the water production time and the machine power-on time.

[0009] The method for identifying the life of the filter element provided by the embodiment of the present invention detects whether the flow meter is abnormal during the operation of the filter element. If no abnormality occurs, the life of the filter element is determined based on the obtained water flow rate and the power-on time of the whole machine. If an abnormality occurs, the life of the filter element is determined based on the obtained water production time and the power-on time of the whole machine. The present invention can accurately identify the life of the filter element by combining the water flow rate, water production time, power-on time of the whole machine and the state of the flow meter, avoid the waste of the filter element due to the unexpired life or the water quality affected by the long use time, and improve the user experience and satisfaction.

[0010] In an optional embodiment, judging whether the life of the filter element has expired is performed based on the water flow rate and the power-on time of the whole machine, including: obtaining the rated water flow rate and the rated power-on time of the filter element; judging whether the water flow rate reaches the rated water flow rate, and if so, judging that the life of the filter element has expired; if not, determining the remaining water production time based on the rated water flow rate, the water flow rate and the water production time, and judging whether the power-on time of the whole machine reaches the rated power-on time, and if so, judging that the life of the filter element has expired.

[0011] The present invention can accurately monitor the water purification condition of the filter element by identifying the filter element life according to the water flow rate and the power-on time of the whole machine when there is no abnormality in the flow meter, and intuitively reflect the impact of the water purification work on the filter element. At the same time, combined with the power-on time of the whole machine, it can avoid the situation where the water is not purified but the power is on for a long time, causing bacteria to grow and affecting the water quality.

[0012] In an optional embodiment, whether the life of the filter element has expired is determined based on the water production time and the whole machine power-on time, including: obtaining the remaining water production time; determining whether the water production time reaches the remaining water production time, and if so, determining that the life of the filter element has expired; if not, determining whether the whole machine power-on time reaches the rated power-on time, and if so, determining that the life of the filter element has expired.

[0013] The present invention can avoid the situation where the flow meter is damaged and the filter element life cannot be identified by identifying the filter element life according to the water production time and the whole machine power-on time when the flow meter is abnormal, thereby improving the user experience.

[0014] In an optional embodiment, the remaining water production time is determined based on the rated water flow, the water flow rate and the water production time, including: calculating the difference between the rated water flow and the water flow rate to obtain the remaining water flow; calculating the ratio of the water production time and the water flow rate to obtain the unit water production time; calculating the product of the remaining water flow and the unit water production time to obtain the remaining water production time.

[0015] The present invention uses a flow meter to assist in monitoring the unit water production time of the filter element, and can take into account the situation that the operating capacity of the pump will be reduced during long-term operation, so as to update the remaining water production time and reduce the calculation deviation of the flow meter caused by the reduction of the pump operating capacity.

[0016] In an optional embodiment, the rated water flow rate of the filter element is obtained, including: obtaining the initial water flow rate, the minimum water flow rate and the preset attenuation slope of the filter element; calculating the flow rate difference between the initial water flow rate and the minimum water flow rate, and taking the ratio of the flow rate difference to the attenuation slope as the rated water flow rate.

[0017] The present invention can determine the upper limit of the filtering capacity of the filter element by calculating the rated water flow rate of the filter element, thereby providing a comparison basis for the water flow rate and accurately identifying whether the service life of the filter element has expired.

[0018] In an optional embodiment, the detecting whether the flow meter is abnormal includes: obtaining the number of pulses of the flow meter, if the number of pulses is less than a preset pulse value, determining that the flow meter is abnormal, otherwise determining that the flow meter is not abnormal.

[0019] The present invention detects whether the flow meter is abnormal according to its working state, which can avoid the situation where the filter element life cannot be identified due to the abnormality of the flow meter, resulting in no prompt for element replacement for a long time, and provides users with accurate and reliable element replacement prompts to improve user experience.

[0020] In an optional embodiment, if an abnormality occurs in the flow meter, whether the life of the filter element has expired is determined based on the water production time and the power-on time of the entire machine. The process also includes: if the flow meter returns to normal, the process returns to the step of detecting whether the flow meter has an abnormality; if the flow meter does not have an abnormality, whether the life of the filter element has expired is determined based on the water flow rate and the power-on time of the entire machine.

[0021] The present invention identifies the filter element life by the water flow rate when the flow meter returns to normal, and can select a relatively more intuitive and accurate identification method, thereby avoiding errors caused by reduced pump operating capacity due to long-term water production and improving the accuracy of filter element life identification.

[0038] 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.

[0039] The embodiment of the present invention is applicable to the scenario of identifying the life of the filter element during the water purification process of the water purification equipment, so as to provide the user with a prompt for changing the filter element in a timely manner. Taking the water purifier as an example, the embodiment of the present invention provides a method for identifying the life of the filter element, which achieves the effect of accurately identifying the life of the filter element by comprehensively analyzing the water flow rate, water production time, whole machine power-on time and flow meter status.

[0040] According to an embodiment of the present invention, an embodiment of a method for identifying the life of a filter element 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.

[0041] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 1 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0042] Step S101, during the operation of the filter element, obtaining the water flow rate, water production time and whole machine power-on time of the filter element.

[0043] Specifically, in an embodiment of the present invention, the water purifier implements physical filtration and chemical filtration through a filter element, thereby removing impurities, odors or harmful substances in the water. As an important component of the water purifier, the filter element will gradually reduce its filtering effect as the water purification time increases, and may also cause blockages, increase the risk of bacterial growth, etc., so it is necessary to remind the user to replace it in time. By deploying a flow meter on the water purifier, the embodiment of the present invention can measure the water flow through the filter element during the operation of the filter element, which is used to control the water output on the one hand and measure the water flow through the filter element on the other hand. At the same time, after the water purifier is powered on, regardless of whether water purification is performed, the power-on time of the whole machine is recorded, and when the filter element filters the water flow to make water, the water making time is recorded, so the power-on time of the whole machine must be greater than the water making time.

[0044] Step S102, detecting whether the flow meter is abnormal.

[0045] Specifically, in an embodiment of the present invention, the flowmeter, as an electronic device, will inevitably cause abnormal conditions due to various reasons, including flowmeter damage, blockage, water source switch problems, accessory failure, insufficient water pump boost, pipe bending or deformation, low water temperature, insufficient output power of the power adapter, etc. In this case, if the water purifier can still prepare purified water normally, the water flow rate of the filter element is still increasing, but the flowmeter cannot measure it, resulting in the inability to accurately identify whether the life of the filter element has expired. Therefore, the embodiment of the present invention obtains the number of pulses of the flowmeter according to the working status of the flowmeter. If the number of pulses is less than the preset pulse value, it is determined that the flowmeter is abnormal, otherwise it is determined that the flowmeter is not abnormal. Then, when an abnormality occurs or no abnormality occurs, the life of the filter element is identified by comprehensively considering the water flow rate of the filter element, the water production time and the power-on time of the whole machine.

[0046] Step S103: If the flow meter is normal, determine whether the life of the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0047] Specifically, in the embodiment of the present invention, because the water flow rate can intuitively reflect the current working condition of the water purifier filter element, the greater the water flow rate, the shorter the life of the filter element. Therefore, when there is no abnormality in the flow meter, it is preferred to judge whether the life of the filter element has expired based on the water flow rate. At the same time, considering that the water purifier may have a small user water consumption or is not used for a long time, at this time, although the water flow rate of the filter element is not large, the filter element may breed bacteria if it is used for too long, thereby affecting the water quality and being harmful to the health of the user. Therefore, while identifying the life according to the water flow rate, judging whether the life of the filter element has expired based on the power-on time of the water purifier can further improve the accuracy of the filter element life identification.

[0048] Step S104: If the flow meter is abnormal, determine whether the life of the filter element has expired based on the water production time and the power-on time of the whole machine.

[0049] Specifically, in the embodiment of the present invention, although the water production time recorded by the filter element during the water purification process cannot directly reflect the working state of the filter element compared with the water flow rate, it can also indirectly reflect the current state of the filter element, that is, the longer the water production time, the greater the usage of the filter element, and the shorter the life of the filter element. Therefore, in the embodiment of the present invention, when an abnormality occurs in the flow meter, the filter element life is judged based on the water production time to determine whether the life of the filter element has expired, which can avoid the situation where the flow meter abnormality cannot be identified and the filter element life cannot be prompted. At the same time, it is still considered that the water purifier may have a small user water consumption or is not used for a long time. At this time, although the water production time of the filter element does not increase much, the filter element has been used for too long. Therefore, while the life is identified based on the water production time, the accuracy of the filter element life identification can be further improved by judging whether the life of the filter element has expired based on the power-on time of the water purifier.

[0050] The method for identifying the life of the filter element provided by the embodiment of the present invention detects whether the flow meter is abnormal during the operation of the filter element. If no abnormality occurs, the life of the filter element is determined based on the obtained water flow rate and the power-on time of the whole machine. If an abnormality occurs, the life of the filter element is determined based on the obtained water production time and the power-on time of the whole machine. The present invention can accurately identify the life of the filter element by combining the water flow rate, water production time, power-on time of the whole machine and the state of the flow meter, avoid the waste of the filter element due to the unexpired life or the water quality affected by the long use time, and improve the user experience and satisfaction.

[0051] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 2 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0052] Step S201, during the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0053] Step S202: Check whether the flow meter is abnormal. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0054] Step S203: If the flow meter is normal, determine whether the life of the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0055] Specifically, the above step S203 includes:

[0056] Step S2031, obtaining the rated water flow rate and rated power-on time of the filter element.

[0057] Specifically, in the embodiment of the present invention, after each filter element is produced, the rated water flow rate and rated power-on time can be determined according to the filtering capacity of the filter element. The maximum use time of the filter element after power-on is set according to the requirements of the filter element drawing, that is, the rated power-on time of the filter element is determined; the attenuation of the water flow rate QB of the filter element is tested according to the material and area of ​​the filter element in combination with the whole system under the standard solution working condition to obtain the attenuation slope k, and at the same time obtain the initial water flow rate QB of the filter element 初始 and minimum water flow rate QB 终止 , initial water flow rate QB 初始 The minimum water flow rate QB is the water flow rate of the new filter element. 终止 The minimum flow rate required by the water purifier system is used to calculate the initial water flow rate QB 初始 and minimum water flow rate QB 终止The flow rate difference ΔQB between the two is taken, and the ratio of the flow rate difference ΔQB to the attenuation slope k is taken as the rated water flow L. The calculation formula is as follows:

[0058] L=(QB 初始 -QB 终止 ) / k=ΔQB / k

[0059] Step S2032, determining whether the water flow rate reaches the rated water flow rate, and if so, determining that the filter element has expired.

[0060] Specifically, in the embodiment of the present invention, Figure 3 As shown, the real-time water flow rate l of the filter element is measured by the flow meter, and it is determined whether the water flow rate l exceeds the rated water flow rate L. If it exceeds, it is determined that the filter element has expired, and a reminder to replace the filter element is issued to the user.

[0061] Step S2033, if not reached, determine the remaining water production time according to the rated water flow, water flow rate and water production time, and judge whether the whole machine power-on time reaches the rated power-on time. If reached, determine that the filter element life expires.

[0062] Specifically, in the embodiment of the present invention, if the water flow rate l of the filter element does not exceed the rated water flow rate L, it proves that the filter element can still work normally at this time. However, due to the differences in water use patterns of different users, some users have a large water consumption, so the power-on time of the whole machine is relatively short, while some users have a small water consumption, or may not be used for a long time, in which case the power-on time of the whole machine is relatively long. As long as the filter element is powered on and starts working, regardless of whether the water volume is large or small, the probability of bacteria breeding will increase with the increase of time. Therefore, if Figure 3 As shown, in the embodiment of the present invention, when the water flow rate l does not exceed the rated water flow rate L, the whole machine power-on time t of the water purifier is 上电 If the power-on time of the whole machine reaches the rated power-on time t 通电 , it is determined that the filter element life has expired. If not, it is operating normally.

[0063] In some optional implementations, in order to prevent the flow meter from being abnormal and unable to determine whether the filter element is expired, the water production time t 制水 However, since the pump's operating capacity (water flow per unit time) will decrease during long-term operation, the lower the capacity, the slower the water production speed, resulting in a gradual increase in the time required to produce the same amount of water. Therefore. Figure 3 As shown, in the embodiment of the present invention, the flow meter is used to assist in real-time monitoring of the pump operation time per unit flow rate, that is, the unit water production time t 单位 , correct the flow rate and calculation deviation caused by the reduction of pump operation capacity, that is, when there is no abnormality in the flow meter, update the remaining water production time t of the filter element in real time 剩余The calculation process is as follows: Calculate the difference between the rated water flow L and the water flow l to obtain the remaining water flow L 剩余 ; Calculate water production time t 制水 The ratio of the water flow rate l to obtain the unit water production time t 单位 ; Calculate the remaining water volume L 剩余 and unit water production time t 单位 The remaining water production time t is obtained by multiplying 剩余 , the calculation formula is as follows:

[0064]

[0065] The method for identifying the life of the filter element provided by the embodiment of the present invention detects whether the flow meter is abnormal during the operation of the filter element. If no abnormality occurs, the life of the filter element is determined based on the obtained water flow rate and the power-on time of the whole machine. If an abnormality occurs, the life of the filter element is determined based on the obtained water production time and the power-on time of the whole machine. The present invention can accurately identify the life of the filter element by combining the water flow rate, water production time, power-on time of the whole machine and the state of the flow meter, avoid the waste of the filter element due to the unexpired life or the water quality affected by the long use time, and improve the user experience and satisfaction.

[0066] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 4 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0067] Step S401: During the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0068] Step S402: Check whether the flow meter is abnormal. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0069] Step S403: If the flow meter is abnormal, determine whether the life of the filter element has expired based on the water production time and the power-on time of the whole machine.

[0070] Specifically, the above step S403 includes:

[0071] Step S4031, obtaining the remaining water production time.

[0072] Specifically, in the embodiment of the present invention, when the flow meter is normal, the rated water flow L, the water flow l and the water production time t 制水 Real-time update of remaining water production time t剩余 Therefore, when the flow meter is abnormal, the latest remaining water production time t can be obtained. 剩余 , this time is determined based on the current pump operating capacity.

[0073] Step S4032, determining whether the water production time reaches the remaining water production time, and if so, determining that the filter element has expired.

[0074] Specifically, in the embodiment of the present invention, Figure 3 As shown in the figure, when the filter element life cannot be identified based on the water flow rate, the water production time t 制水 Whether the remaining water production time t is exceeded 剩余 To determine whether the filter element has expired. 制水 Exceeding the remaining water production time t 剩余 , which proves that the filter element has been working for a long time and can no longer meet user needs. The filter element is judged to have expired and the user is prompted to replace the element.

[0075] Step S4033: If not, determine whether the whole machine power-on time has reached the rated power-on time. If so, determine that the filter element life has expired. Figure 2 Step S2033 of the illustrated embodiment will not be described in detail here.

[0076] Step S404, if the flow meter returns to normal, then return to the step of detecting whether the flow meter is abnormal; if the flow meter is not abnormal, then determine whether the life of the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0077] Specifically, in the embodiment of the present invention, if the flow meter is abnormal, the water purifier will remind the user to replace the flow meter. After the flow meter is replaced, the measurement of the water flow rate through the filter element will be restored, so it is switched to judging whether the life of the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0078] The method for identifying the life of the filter element provided by the embodiment of the present invention detects whether the flow meter is abnormal during the operation of the filter element. If no abnormality occurs, the life of the filter element is determined based on the obtained water flow rate and the power-on time of the whole machine. If an abnormality occurs, the life of the filter element is determined based on the obtained water production time and the power-on time of the whole machine. The present invention can accurately identify the life of the filter element by combining the water flow rate, water production time, power-on time of the whole machine and the state of the flow meter, avoid the waste of the filter element due to the unexpired life or the water quality affected by the long use time, and improve the user experience and satisfaction.
