[0051] The present application is further illustrated by the following examples without thereby limiting the present application to the scope of the examples.

[0052] Embodiment 1

[0053] The present embodiment provides a filter core life monitoring correction method applied to a water purifier with a hot water tank, referring to Figure 1 , the filter core life monitoring correction method comprises:

[0054] S1, after the water purifier is powered on, the cumulative use time of the filter core, the last power-on time of the water purifier, the last power-on water temperature of the hot water tank, and the current temperature of the hot water tank are obtained.

[0055] S2, according to the last power-on time, the last power-on water temperature, and the current temperature, the correction time of the filter core life is determined.

[0056] The current temperature includes the current water temperature and the current tank temperature.

[0057] In an optional embodiment, the step of obtaining the current temperature of the hot water tank in step S1 comprises:

[0058] S11, the water level of the hot water tank is obtained.

[0059] S12, if the water level is greater than the water level threshold, the current water temperature of the hot water tank is obtained.

[0060] The water level threshold is set according to actual needs.

[0061] Step S2 comprises:

[0062] S21, according to the last power-on time, the last power-on water temperature, and the current water temperature, the correction time of the filter core life is determined.

[0063] In an optional embodiment, after step S11 comprises:

[0064] S111, if the water level is less than or equal to the water level threshold, the current tank temperature in the hot water tank is obtained.

[0065] Step S2 comprises:

[0066] S22, according to the last power-on time, the last power-on water temperature, and the current tank temperature, the correction time of the filter core life is determined.

[0067] S3, according to the sum of the cumulative use time of the filter core and the correction time, the used life of the filter core is determined.

[0068] The embodiment is used for a water purifier with a hot water tank. The service life of a filter core is corrected and compensated according to the temperature characteristics that the temperature in the hot water tank slowly decreases with the increase of the power-off time, the last power-on duration of the water purifier, the last power-on water temperature of the hot water tank and the current temperature of the hot water tank. The used service life of the filter core is determined according to the sum of the cumulative use duration of the filter core and the corrected duration of the filter core, so as to reduce the error between the predicted used service life of the filter core and the real used service life, provide a more accurate filter core replacement time node without networking and increasing the cost, ensure the water safety of the product and improve the user experience.

[0069] In an optional embodiment, step S21 comprises:

[0070] When the last power-on duration is less than the first preset duration, or when the time difference between the product and the first preset threshold is greater than the preset time difference, the product is determined as the corrected duration of the filter core. The product is the product of the difference value, the temperature drop coefficient and the water level coefficient, and the difference value is the difference between the last power-on water temperature and the current water temperature.

[0071] The temperature drop coefficient is the time consumed for the temperature to drop by one degree under the full water state. The water level coefficient is the constant value of the heat dissipation speed under different water level states. Generally, the full water is 1, the medium water level is 0.7, and the low water level is 0.5.

[0072] When the last power-on duration is greater than or equal to the first preset duration, and the time difference between the product and the first preset threshold is less than or equal to the preset time difference, the first preset threshold is determined as the corrected duration of the filter core. When the last power-on duration is greater than or equal to the first preset duration, it is extremely possible that the user's power-off habit is to power off every night or every weekend.

[0073] The first preset duration, the first preset threshold and the preset time difference are set according to the actual situation.

[0074] The following introduces an example of the flow steps for determining the corrected duration of the filter core when the water level in the hot water tank of the water purifier before the last power-off is greater than the water level threshold. It should be noted that the values in the example are only empirical values, and the values of the embodiment are not limited to these empirical values. For example, Figure 2 As shown in the following table:

[0075] S201, it is judged whether the last power-on duration is less than 8 hours. If yes, it is indicated that the use time of the water purifier is irregular, the used service life of the filter core needs to be corrected and compensated according to the temperature characteristics that the temperature in the hot water tank slowly decreases with the increase of the power-off time, step S202 is executed, otherwise, step S205 is executed.

[0076] S202, the corrected duration of the filter core is calculated according to the temperature characteristics formula.

[0077] The temperature characteristic formula used in this example is as follows:

[0078] The correction period for filter cartridge life = (last power-on water temperature - current water temperature) * cooling coefficient * water level coefficient.

[0079] The cooling coefficient is the time it takes for the temperature to drop by one degree Celsius when the water is full. The water level coefficient is a constant value for the heat dissipation rate under different water levels. Generally, it is taken as 1 for full water, 0.7 for medium water level, and 0.5 for low water level.

[0080] S203. Determine the service life of the filter element based on the sum of the cumulative usage time and the correction time.

[0081] S204. Set the power-on flag of the water purifier to 1, indicating that the water purifier has been powered on for a period of time after being powered off, and end this example process.

[0082] S205. Determine whether the duration of the last power-on was greater than or equal to 8 hours and less than or equal to 16 hours, that is, determine whether the user's power-off habit is to cut off the power every night. If so, proceed to step S206; otherwise, proceed to step S207.

[0083] S206, Proceed to the process step of determining the correction duration of the filter cartridge life based on the user's nightly power outage habits, and return to S203.

[0084] S207. Determine whether the last power-on duration is greater than or equal to 4.5 days and less than or equal to 7 days. If so, determine whether the user's power-off habit is to cut off power every weekend. Then proceed to step S208. Otherwise, return to step S202.

[0085] S208, Proceed to the process step of determining the correction period for filter life based on the user's power outage habits every weekend, and return to S203.

[0086] The process steps for determining the adjustment period for filter life based on the user's nightly power outage habits are as follows: Figure 3 As shown:

[0087] S301. The difference between 24 hours and the last power-on time is determined as the first correction time for the filter life.

[0088] S302. Calculate the second correction duration of the filter element life based on the temperature characteristic formula.

[0089] S303. Determine whether the difference between the first correction duration and the second correction duration is greater than 2 hours. If yes, proceed to step S304; otherwise, proceed to step S305.

[0090] S304. The second correction duration is determined as the correction duration for the filter element life.

[0091] S305, determining the first correction duration as the correction duration of the filter life.

[0092] The process of determining the correction duration of the filter life according to the power-off habit of the user every weekend is shown in the following steps: Figure 4

[0093] S401, determining the difference between 168 hours and the last power-on duration as the first correction duration of the filter life.

[0094] S402, calculating the second correction duration of the filter life according to the temperature characteristic formula.

[0095] S403, determining whether the difference between the first correction duration and the second correction duration is greater than 8 hours, if yes, executing step S404, otherwise, executing step S405.

[0096] S404, determining the second correction duration as the correction duration of the filter life.

[0097] S405, determining the first correction duration as the correction duration of the filter life.

[0098] In the embodiment, the water in the hot water tank is not discharged before the last power-off of the water purifier, the power-off duration of the water purifier is calculated according to the characteristic that the water temperature in the hot water tank slowly decreases with the increase of the power-off time and the power-off habit of the user, and the use duration of the filter is compensated according to the actual situation, so that the correction duration of the filter life is determined from multiple angles, and the determined used life of the filter is more accurate and reliable.

[0099] In an optional embodiment, step S22 includes:

[0100] When the current tank temperature is less than the first temperature threshold, and the last power-on water temperature is greater than the second temperature threshold, if the last power-on duration is less than or equal to the second preset duration, the second preset threshold is determined as the correction duration of the filter life.

[0101] When the current tank temperature is less than the first temperature threshold, and the last power-on water temperature is less than or equal to the second temperature threshold, if the last power-on duration is greater than the second preset duration, the third preset threshold is determined as the correction duration of the filter life.

[0102] If the last power-on duration is greater than the second preset duration, it means that the power-off habit of the user is most likely to be power-off every night or every weekend.

[0103] The first temperature threshold, the second temperature threshold, the second preset duration, the second preset threshold and the third preset threshold are set according to the actual situation.

[0104] ​A flowchart example of determining the corrected service life of the filter cartridge when the water level in the hot water tank before the last power-off is less than or equal to the water level threshold is introduced below. It should be noted that the values in the example are only empirical values, and the values of the present embodiment are not limited to these empirical values. For example, Figure 5

[0105] S501, determine whether the current tank temperature is less than 40 degrees, if not, it means that the power-off time of the water purifier is short, for example, within 2 hours, execute step S502, if yes, execute step S503.

[0106] S502, mark the power-on flag of the water purifier as 1, indicating that the water purifier has been powered on for a period of time after power-off, and end the example flow.

[0107] S503, determine whether the last power-on water temperature is greater than 80 degrees, if yes, it means that the power-off time of the water purifier is long, and the temperature in the hot water tank has approached room temperature, execute step S504, otherwise, execute step S509.

[0108] S504, determine whether the last power-on duration is less than 8 hours, if yes, it means that the use time of the water purifier is irregular, and the used service life of the filter cartridge needs to be corrected and compensated according to the temperature characteristics that the water temperature in the hot water tank will slowly decrease with the increase of the power-off time, execute step S505, otherwise, execute step S507.

[0109] S505, determine 12 hours as the corrected service life of the filter cartridge.

[0110] S506, determine the used service life of the filter cartridge according to the sum of the cumulative use duration of the filter cartridge and the corrected duration, and return to step S502.

[0111] S507, determine whether the last power-on duration is greater than or equal to 8 hours and less than or equal to 16 hours, i.e., whether the power-off habit of the user is to power off every night, if yes, execute step S510; otherwise, execute step S508.

[0112] S508, determine whether the last power-on duration is greater than or equal to 4.5 days and less than or equal to 7 days, if yes, i.e., whether the power-off habit of the user is to power off every weekend, execute step S511; otherwise, return to step S505.

[0113] S509, determine whether the last power-on duration is greater than 8 hours, if yes, it means that the water purifier is used a lot before the last power-off, and the power-off time is long, return to step S504; otherwise, it means that the water purifier is powered off during maintenance, and the power-off time is short, return to step S502.

[0114] S510, execute Figure 3 ​The process steps of determining the modified length of filter core life according to the power-off habit of the user powering off every night are executed, and the process returns to step S506.

[0115] S511, the process steps of determining the modified length of filter core life according to the power-off habit of the user powering off every weekend are executed, and the process returns to step S506. Figure 4

[0116] In the present embodiment, the water in the hot water tank is drained before the last power-off of the water purifier, so the length of power-off of the water purifier can only be roughly estimated according to the current tank temperature of the hot water tank. The present embodiment further estimates the length of power-off of the water purifier according to the power-off habit of the user, and further compensates the length of use of the filter core according to the actual situation, so as to determine the modified length of filter core life from multiple angles, and ensure that the determined used life of the filter core is more accurate and reliable.

[0117] In an optional embodiment, the filter core life monitoring and modifying method further comprises:

[0118] S4, after the water purifier is powered on, the storage time is determined according to the user water taking time difference.

It should be noted that the values in the example are only empirical values, and the values of the present embodiment are not limited to these empirical values.

[0122] As shown in Figure 6

[0123] S601, it is judged whether someone takes water, if yes, step S602 is executed, otherwise, step S607 is executed.

[0124] S602, mark the present water taking as the first water taking within a day, and start timing.

[0125] S603, it is judged whether someone takes water again, if yes, step S604 is executed, otherwise, step S607 is executed.

[0126] S604, it is judged whether the water taking time difference is greater than 6 hours, if yes, it is explained that the water taking between the two times is at night, so the second water taking is the first water taking in the daytime, and the process returns to step S602. Otherwise, it is explained that it is daytime, continue timing, and execute step S605.

[0127] ​​S605, determining whether the time is greater than 8 hours, if yes, it means that the current time is probably in the evening, the user may power off the water purifier at any time, and step S606 is executed; otherwise, step S604 is returned.

[0128] S606, storing the current water temperature and water level of the hot water tank at the current storage time.

[0129] S607, waiting for someone to take water. In the embodiment, in order to reduce the occupation of storage memory, the best storage time of storing the water temperature and water level of the hot water tank is determined according to the time difference when the user takes water on the premise of meeting the user's power-off habits. The storage efficiency is improved, and the waste of storage resources is reduced.

[0130] In an optional embodiment, the filter core life monitoring correction method further comprises:

[0131] S6, if the difference between the current water temperature of the hot water tank and the water temperature at the storage time exceeds the preset temperature difference, the current water temperature of the hot water tank is stored.

[0132] The preset temperature difference is set according to the actual situation.

[0133] In the embodiment, the water temperature of the hot water tank stored at the storage time may be greatly different from the current water temperature. At this time, the current water temperature of the hot water tank is re-stored to further improve the accuracy of the filter core service life inferred according to the temperature characteristics.

[0134] In an optional embodiment, the filter core life monitoring correction method further comprises:

[0135] S7, if the difference between the current water level of the hot water tank and the water level at the storage time exceeds the preset water level difference, the current water level of the hot water tank is stored.

[0136] The preset water level difference is set according to the actual situation.

[0137] The following introduces a process step of updating the storage of the water temperature and water level of the hot water tank at a better frequency. It should be noted that the numerical values in the example are only empirical values, and the numerical values of the embodiment are not limited to these empirical values.

[0138] As shown in Figure 7 , the following introduces a process step of updating the storage of the water temperature and water level of the hot water tank at a better frequency. It should be noted that the numerical values in the example are only empirical values, and the numerical values of the embodiment are not limited to these empirical values.

[0139] S701, determining whether the difference between the current water temperature and the water temperature at the storage time is greater than 5 degrees, if yes, step S702 is executed, otherwise, step S703 is executed.

[0144] In the present embodiment, the water level of the hot water tank stored at the storage time can be greatly different from the current water level, at this time, the current water level of the hot water tank is newly stored, since the current water level is related to the inferred service life of the filter element, so the accuracy of the filter element service life inferred according to the temperature characteristics can be improved.

[0145] Next, an example of a filter element service life monitoring correction method of a water purifier with a hot water tank is introduced, Figure 8 is a flowchart of the example.

[0146] S801, the water purifier is powered on.

[0147] S802, the power-on flag of the water purifier is marked as 0, and the last power-on duration is read.
