Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the invention are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Dish washers are used as equipment in modern kitchens for automatically cleaning items such as bowls, dishes, chopsticks, etc. that need to be cleaned. In the process of cleaning, the dish washer mainly relies on a washing pump to send water softened by the water softener into a washing circulation waterway, and the water is output through a spraying device, a flushing device and the like at the tail end of the washing circulation waterway to clean articles to be cleaned.

So that when the washing pump fails, the normal operation of the dishwasher cannot be ensured. In addition, the water softener in the dish washer mainly performs the softening operation on water by replacing water hardening substances (such as calcium ions, magnesium ions and other metal examples) in tap water by virtue of the replacement substances arranged in the water softener, so that the problems that scale is easily accumulated on a water spray arm, a liner and other parts of the dish washer, a water spray hole of the dish washer is blocked and the washing effect is influenced due to the fact that the dish washer is washed by tap water which is not softened for a long time are avoided.

In order to solve the problems, the application provides a method for monitoring the operation states of a washing pump and a water softener so as to discover timely and take corresponding measures under the condition that the operation states of the washing pump and the water softener are abnormal.

Since the method for monitoring the running state is applied to the washing device, the washing device is a dishwasher, a water tank with a washing function and the like. First, a structure related to the present application in a washing apparatus will be described, as shown in fig. 1, and fig. 1 is a washing apparatus according to an embodiment of the present application.

As shown in fig. 1, the washing apparatus 10 includes a processing module 101, a washing pump 102, a water softener 103, a washing circulation water path, and a sensor 104 disposed on the circulation water path.

The processing module 101 is, for example, a control circuit, a control chip, or the like having the capability of calculating, analyzing, processing, transmitting instructions, receiving signals, or the like, of signals, data, or the like. The processing module 101 is illustratively a single-chip microcomputer.

The water softener 103 is provided therein with a water softening chamber 1031 and a displacing material receiving chamber 1032, and the water softening chamber 1031 is provided therein with a water softening material such as a resin; the replacement substance storage chamber 1032 is provided with a replacement substance, such as a salt, for replacing the water hardening substance attached to the water softening substance.

The water softener 103 is used to replace metal ions (e.g., sodium ions, magnesium ions, etc.) in tap water by sodium ions in the water softening substance to achieve softening of tap water.

After the water softener 103 softens tap water with the water softening substance for a while, the water softening substance adheres with the metal ions to be replaced, resulting in a decrease in softening ability of tap water, and at this time, the metal ions adhering to the water softening substance need to be replaced again by the replacement substance and discharged to secure the water softening effect of the water softening substance.

The washing pump 102 is used to feed tap water softened by the water softening substances in the water softener 103 into the washing circulation waterway and spray the tap water through a spray device, a flushing device and the like at the end of the washing circulation waterway so as to clean tableware.

A sensor 104 is provided in the wash circulation water path, the sensor 104 being capable of emitting and receiving a spectrum and determining the concentration of the hydraulic substance (i.e. the concentration of the metal ions) from the change in the spectrum. The sensor 104 is, for example, an IR sensor 104.

Based on the structure of the washing apparatus 10 shown in fig. 1, a method for monitoring an operation state provided in the present application will be described with reference to fig. 2, and the method includes the following steps:

Step S20, receiving concentration data sent by the sensor 104, wherein the concentration data is the concentration of the water hardening substance determined by the sensor 104 through detecting the spectrum change condition in the washing circulation waterway;

wherein concentration data transmitted from a sensor 104 provided on the washing circulation line may be received by the processing module 101 in the washing apparatus 10. The concentration data is concentration data determined by the sensor 104 based on the emitted spectrum and the received reflection spectrum, based on the difference between the emitted spectrum and the received spectrum. The concentration data may be single data or may be a collection of multiple data, as not limited in this application.

The sensor 104 may send the collected concentration data to the processing module 101 at any time after the washing device 10 is started, or may obtain the concentration data based on an obtaining instruction of the processing module 101, or may send the concentration data to the processing module 101 once at a preset time interval, which is not limited in this application.

With reference to the description of the structure of the washing apparatus 10 of fig. 1, when the washing apparatus 10 is in the washing mode and the operation state of the washing pump 102 is normal, the softened water in the water softener 103 is introduced into the washing circulation water path by the washing pump 102, so that the softened water flows out of the shower head or the like at the end of the washing circulation water path through the washing circulation water path to wash the dishes. In contrast, if the operation state of the wash pump 102 is abnormal, no softened water flows into the wash cycle water path.

Further, since the sensor 104 is provided in the washing cycle water path of the present application, whether or not the operation state of the washing pump 102 is normal can be determined by whether or not the sensor 104 detects the concentration data of the softened water.

Based on the above principle, the processing module 101 may send an acquisition instruction to the sensor 104 when the washing apparatus 10 is in the washing mode, and receive the concentration data sent by the sensor 104 based on the acquisition instruction after a preset period of time, so as to determine the operation state of the washing pump 102 according to the concentration data. The processing module 101 may also be configured to receive the concentration data sent by the sensor 104 from time to time or intermittently while the washing apparatus 10 is in the washing mode, and determine the operation state of the washing pump 102 based on the concentration data.

Illustratively, the user a turns on the washing device 10 at 12:30 and adjusts the washing device 10 to a dish washing mode by touching the buttons, and the processing module 101 sends an acquisition instruction to the sensor 104 when determining that the washing device 10 is in the dish washing mode, and receives the concentration data sent by the sensor 104 at 12:31.

Step S30 of determining whether the operation state of the washing pump 102 in the washing apparatus 10 is normal or not based on the concentration data;

the processing module 101 may determine whether the operation state of the wash pump 102 in the washing device 10 is normal by calculating, analyzing, comparing, etc. the processing result after receiving the concentration data sent by the sensor 104. For example, the processing module 101 determines that the operation state of the wash pump 102 is normal in the case where it is determined that the concentration data portion is empty; on the contrary, if the concentration data is determined to be empty, the operation state of the washing pump 102 is determined to be abnormal.

In one embodiment, as shown in fig. 3, fig. 3 is an alternative method embodiment for determining whether the operation state of the wash pump 102 is normal according to an exemplary embodiment of the present application, where the method embodiment includes the following steps:

step S301, comparing the concentration data with a concentration threshold;

the concentration threshold may be one obtained from a test or one obtained from an empirical value, which is not limited in this application.

The concentration threshold may be stored in a memory address of the processing module 101, and when the processing module 101 receives the concentration data sent by the sensor 104, the concentration threshold may be read from the corresponding memory address, and the concentration data is compared with the concentration threshold.

The method of comparing the concentration data to the concentration threshold includes at least one of comparing the concentration data to the concentration threshold, differencing, comparing, calculating a mean, calculating a variance, and the like, which is not limited in this application.

Step S302, if the concentration data is smaller than the concentration threshold value, determining that the operation state of the washing pump 102 is abnormal;

after comparing the concentration data with the concentration threshold, the processing module 101 compares the concentration data with the concentration threshold, where the comparison result includes that the concentration data is smaller than the concentration threshold and the concentration data is greater than or equal to the concentration threshold, and then the application may determine that the operation state of the wash pump 102 is abnormal if the comparison result is that the concentration data is smaller than the concentration threshold.

In step S303, if the concentration data is equal to or greater than the concentration threshold, it is determined that the operation state of the wash pump 102 is normal.

Likewise, based on the second comparison result, the processing module 101 may determine that the operation state of the wash pump 102 is normal.

The present application provides a method for determining whether the operation state of the wash pump 102 is normal, as shown in fig. 4, comprising the steps of:

step S401, calculating an average value of a plurality of sub-concentration data;

in order that the processing module 101 may determine whether the operation state of the wash pump 102 is normal according to the plurality of data, and based on the above description, the concentration data received by the processing module 101 from the sensor 104 may include a plurality of sub-concentration data, and after receiving the plurality of sub-concentration data, the processing module 101 may calculate an average value of the plurality of sub-concentration data first, so as to determine the operation state of the wash pump 102 according to the concentration average value, so that a one-cut determination manner may be avoided, and the determination may be more accurate.

Step S402, if the average value is smaller than the concentration threshold value, determining that the running state of the washing pump 102 is abnormal;

the concentration threshold is the same as the concentration threshold appearing above, and is not described herein, and may be obtained by a test, or may be set according to an empirical value, which is not limited in this application. When the processing module 101 calculates the average value of the plurality of sub-concentration data, the average value of the plurality of sub-concentration data may be obtained by reading the concentration threshold value from the corresponding memory address, and comparing the average value with the concentration threshold value, where the comparison method may still be at least one of comparison, difference making, comparison, calculation method, and absolute value calculation.

The obtained comparison result can still comprise two types: the average value is greater than the concentration threshold and the average value is less than or equal to the concentration threshold.

The processing module 101 may determine that the operating state of the wash pump 102 is abnormal if the average value is less than the concentration threshold value.

In step S403, if the average value is equal to or greater than the concentration threshold value, it is determined that the operation state of the wash pump 102 is normal.

Likewise, the processing module 101 may determine that the operation state of the wash pump 102 is normal in the case where it is determined that the average value is equal to or greater than the concentration threshold value.

In another embodiment, if the processing module 101 determines that the operation state of the wash pump 102 is abnormal, the following operations may be performed, as shown in fig. 5:

step S501, if the operation state of the washing pump 102 is determined to be abnormal, the number of times of recording the operation state abnormality of the washing pump 102 is automatically increased;

the processing module 101 may store a record of the abnormal operation state of the washing pump 102, where the record may include a time and a number of times when the processing module 101 determines that the abnormal operation state of the washing pump 102 occurs. If the processing module 101 determines that the operation state of the wash pump 102 is abnormal for multiple times within a preset period of time, the operation state of the wash pump 102 may be automatically increased by recording the number of abnormal times each time the operation state of the wash pump 102 is determined, or may be automatically increased in a sequentially increasing order or in an interval increasing order, which is not limited in this application.

Illustratively, the record table includes the following:

in step S502, if the number of times of abnormal operation of the washing pump 102 reaches the threshold number of times, an alarm message is generated and the washing pump 102 is controlled to stop working.

The frequency threshold may be one data obtained by experiment, or one data obtained by experience, which is not limited in this application. The frequency threshold is stored in a memory address fixed by the processing module 101, and the processing module 101 may acquire the total number of abnormal running states of the washing pump 102 after each update of the record table, then read the frequency threshold from the corresponding memory address, compare the frequency with the frequency threshold, and determine an operation to be executed according to the comparison result.

The processing module 101 may generate an alarm message and control the wash pump 102 to stop operating when the determined number of times reaches the number of times threshold.

Further, the processing module 101 may send the alarm information to the terminal device corresponding to the user through the network, so that the user can timely find the abnormal state of the washing pump 102 and perform operations such as maintenance, replacement, etc., thereby ensuring the normal use of the washing device 10.

Here, the recording table in the processing module 101 may be recorded in units of months or in units of years, and the present application is not limited thereto. This facilitates viewing by the user or during repair.

The above is an operation step in which the processing module 101 determines whether the operation state of the wash pump 102 is normal based on the concentration data transmitted from the sensor 104, and the above operation steps can be obtained without requiring a complicated calculation process, so that the efficiency of the processing module 101 in determining whether the operation state of the wash pump 102 is normal can be improved.

When the processing module 101 determines that the operation state of the washing pump 102 is normal according to the above steps, no further data need to be acquired, and the operation state of the water softener 103 in the washing device 10 can be further determined by means of the concentration data sent by the sensor 104, which is described in detail in the following steps.

In step S40, in the case where it is determined that the operation state of the washing pump 102 is normal, the operation state of the water softener 103 in the washing device 10 is determined based on the concentration data.

In the case where the processing module 101 determines that the concentration data is equal to or greater than the concentration threshold value, it may be determined that the operation state of the wash pump 102 is normal. That is, the wash pump 102 can send the water in the water softener 103 to the wash circulation water path. Then, the water introduced into the washing cycle water is softened by the water softener 103.

Since the sensor 104 is capable of determining the concentration of the water hardening substance in the water, the effect of the water softener 103 on the softening of the tap water, i.e. the operating state of the water softener 103, can be determined by the concentration of the water hardening substance.

For example, the processing module 101 may determine that the water softener 103 is in an abnormal state when the concentration data is determined to be greater than the concentration threshold, that is, the hardness of the tap water softened by the water softener 103 is still relatively high and the softening requirement cannot be met. Otherwise, it is determined that the operation state of the water softener 103 is normal.

In an alternative embodiment, as shown in fig. 6, fig. 6 is an alternative method embodiment of determining the operational status of the water softener 103 provided in an embodiment of the present application, the method embodiment comprising the steps of:

step S601, determining a first hardness value of water in a washing circulating waterway according to concentration data and a first corresponding relation information table, wherein the first corresponding relation information table comprises a plurality of concentration data and hardness values corresponding to the concentration data;

the first correspondence information table may be pre-stored in a memory address corresponding to the processing module 101; the first correspondence information table may be obtained according to a method such as historical data and test, which is not limited in this application.

The first correspondence information table is exemplary:

since the sensor 104 is disposed in the washing circulation waterway, and water in the washing circulation waterway is flowed from the water softener 103 by the washing pump 102, the softening capacity, i.e., the operating state of the water softener 103 can be determined by the hardness value of the water in the washing circulation waterway.

Therefore, when the processing module 101 receives the concentration data transmitted from the sensor 104 and determines that the operation state of the wash pump 102 is normal according to the concentration data, the concentration data is matched with the first correspondence information table, and a hardness value (to distinguish from other hardness values of the subsequent water, referred to herein as a first hardness value) matched with the concentration data in the wash cycle water path is obtained.

Step S602, if the first hardness value is larger than a first hardness threshold value, determining that the operation state of the water softener 103 is abnormal;

the first hardness threshold may be determined empirically, experimentally, by historical data, etc., and stored in a corresponding memory address of the processing module 101. After the processing module 101 obtains the first hardness value of the water in the washing circulation waterway through the method, the first hardness threshold value is read from the corresponding memory address, the first hardness value is compared with the first hardness threshold value, and the abnormal running state of the water softener 103 is determined under the condition that the comparison result is that the first hardness value is larger than the first hardness threshold value.

In step S603, if the first hardness value is equal to or less than the first hardness threshold value, it is determined that the operation state of the water softener 103 is normal.

Wherein, based on the comparison relationship between the first hardness value and the first hardness threshold, if the first hardness value is less than or equal to the first hardness threshold, the processing module 101 determines that the operation state of the water softener 103 is normal.

According to the method for monitoring the running state, the hardness value of water softened by the water softener 103 is determined through the concentration data collected by the sensor 104, the running state of the water softener 103 is further determined according to the hardness value of the water, the determination process is simple, complex calculation, analysis or judgment is not needed, the number of needed data types is small, and therefore the determination efficiency is high.

In another embodiment, as shown in FIG. 7, FIG. 7 is another alternative method embodiment for determining the operational status of the water softener 103 provided in an embodiment of the present application, the method embodiment comprising the steps of:

step S701, determining a target voltage value according to the concentration data and a second corresponding relation information table, wherein the second corresponding relation information table comprises a plurality of concentration data and voltage values corresponding to the concentration data;

The processing module 101 may further store a second correspondence information table, where the second correspondence information table includes a plurality of density data and voltage values corresponding to the respective density data. The second correspondence information table may be determined based on experience, experiment, history data, etc., which is not limited in this application.

The second correspondence information table is exemplary:

therefore, when the processing module 101 receives the concentration data sent by the sensor 104 and determines that the operation state of the washing pump 102 is normal according to the concentration data, the concentration data is matched with the second correspondence information table, and a voltage value with successful matching is obtained.

For example, if the processing module 101 receives that the concentration data sent by the sensor 104 is concentration data 1, the concentration data 1 is matched with each concentration data in the second correspondence information, and a voltage value 1 matched with the concentration data 1 is obtained.

Step S702, determining a second hardness value of water in the washing circulation waterway according to a target voltage value and a third corresponding relation information table, wherein the third corresponding relation information table comprises a plurality of voltage values and hardness values corresponding to the voltage values;

wherein, the third correspondence table may be pre-stored in a memory address corresponding to the processing module 101; the third correspondence information table may be obtained according to an empirical value, historical data, a test, or the like, which is not limited in this application.

The third correspondence information table includes a plurality of voltage values and hardness values of water corresponding to the respective voltage values.

The third correspondence information table is exemplary:

since the sensor 104 is disposed in the washing circulation waterway, and water in the washing circulation waterway is flowed from the water softener 103 by the washing pump 102, the softening capacity of the water softener 103, i.e., the operation state of the water softener 103, can be determined by the hardness value of the water in the washing circulation waterway. For convenience of distinction, the hardness value obtained by the processing module 101 according to the target voltage value is referred to herein as a second hardness value, which may be the same value as the first hardness value or a different value, which is not limited in this application.

For example, if the processing module 101 determines that the target voltage value is a voltage value of 1 according to the concentration data sent by the sensor 104. And then the hardness value of the water in the circulating waterway is 1 after the voltage value 1 is matched with the third corresponding relation information table.

Step S703, if the second hardness value is greater than the second hardness threshold value, determining that the operation state of the water softener 103 is abnormal;

in step S704, if the second hardness value is equal to or less than the second hardness threshold value, it is determined that the operation state of the water softener 103 is normal.

The second hardness threshold may be the same as the first hardness threshold, or may be a different threshold from the first hardness threshold, which is not limited in the present application. The second hardness threshold may also be a threshold set based on experience, historical data, experimentation, etc. to define the softening function of the water softener 103, i.e., whether the operating condition is normal.

Wherein, after determining the second hardness value of the water in the washing circulation waterway according to the two corresponding relation information tables, the processing module 101 determines that the operation state of the water softener 103 is abnormal when the second hardness value is greater than the second hardness threshold value, and determines that the operation state of the water softener 103 is normal when the second hardness value is less than or equal to the second hardness threshold value.

According to the method for monitoring the running state, the voltage value is determined through the concentration data collected by the sensor 104, the hardness value of water softened by the water softener 103 is determined according to the voltage value, the running state of the water softener 103 is determined according to the hardness value of water, the determination process is simple, the voltage data is added, the running state of the water softener 103 is determined from different data angles, the situation that inaccuracy is caused by single data determination is avoided, however, complex calculation, analysis or judgment is not needed in the whole process, and therefore the determination efficiency can be improved.

Based on the above description of the respective structures and functions of the respective structures in the washing apparatus 10, the water softener 103 replaces the water hardening substances in the tap water with the replacement substances disposed therein, and after the replacement substances in the water softener 103 are replaced for a period of time, the replacement effects (i.e., softening effects) of the replacement substances may be reduced due to the fact that the replaced water hardening substances are more adhered to the replacement substances, the replacement substances consume, the replacement substances age, etc., and the water hardening substances in the replacement substances may be replaced by the replacement substances disposed in the replacement substance receiving chamber 1032 in the water softener 103, so that the purpose of recovering the softening capacity of the water softener 1031 may be achieved. In colloquial terms, the resin flushing operation with brine is performed.

So in the case where the processing module 101 determines that the operation state of the water softener 103 is abnormal, it may be to perform the following operations:

if it is determined that the operation state of the water softener 103 is abnormal, a regeneration operation instruction for performing a regeneration operation on the water softener 103 is generated, the regeneration operation including an ion replacement operation on the water hardening substances in the water softener 103.

Wherein the regeneration operation instruction may be generated in a case where the processing module 101 determines that the operation state of the water softener 103 is abnormal. To instruct the water softening substance in the water softening chamber 1031 to be subjected to a displacing operation by the displacing substance in the water softener 103. Illustratively, it may be that the inlet water flows into the water softening chamber 1031 after being controlled to flow to the displacing material receiving chamber 1032.

In another embodiment, as shown in fig. 8, fig. 8 is an alternative method embodiment provided in the embodiment of the present application after performing a regeneration operation, where the method embodiment includes the following steps:

step S801, after the regeneration operation of the water softener 103, obtaining a third hardness value of the water in the water softener 103;

wherein, the third hardness value of the water in the water softener 103 can be obtained by means of the concentration data of the water in the washing circulation water path obtained by the sensor 104 after the regeneration operation of the water softener 103;

for example, the processing module 101 may obtain the current water hardness value, that is, obtain the third water hardness value, by matching the concentration data obtained after the receiving sensor 104 performs the regeneration operation on the water softener 103 with the first correspondence information table;

The processing module 101 may also match the concentration data with the second correspondence information table to obtain a voltage value, and then match the voltage value with the third correspondence information table to obtain a third hardness value, which is not limited in this application.

Step S802, if the third hardness value is greater than the first hardness threshold value or the second hardness threshold value, detecting whether the water softener 103 lacks a replacement substance;

wherein, the first hardness threshold value may be the same threshold value as the second hardness threshold value or may be a different threshold value, and the threshold value may be a threshold value for determining the softening capacity of the water softener 103, so when the processing module 101 obtains the third hardness value based on any method, the third hardness value is compared with the first hardness threshold value or the second hardness threshold value, and whether the effect of the regeneration operation is poor or not due to the lack of replacement substances or insufficient number of regeneration operations in the water softener 103 is determined according to the comparison result. The displacing substance is for example a salt.

Specifically, if the comparison is that the third hardness value is greater than the first hardness threshold or the second hardness threshold, the processing module 101 needs to determine whether the water softener 103 is devoid of the replacement material.

In the washing device 10, a detection device 1033 for detecting the absence of the replacement substance may be provided in the replacement substance accommodation chamber 1032, and the detection device 1033 may be, for example, the content sensor 104 or the like.

The processing module 101 may send an acquisition instruction to the detection device 1033 after determining that the third hardness value is greater than the first hardness threshold value or the second hardness threshold value, and receive data sent by the detection device 1033 based on the acquisition instruction, to determine whether the replacement material is absent from the water softener 103 based on the data.

Step S803, if the replacement substance is absent, a prompt message is generated, and the prompt message is used for prompting a user to add the replacement substance;

the processing module 101 may send a prompt message to prompt the user to add the replacement material in time when the terminal device of the line user determines that the replacement material is absent based on the above process.

In another embodiment, the processing module 101 may continue to generate a regeneration operation instruction to perform a regeneration operation on the water softening substance after determining that the replacement substance has been added, and continue to acquire the hardness of the water softened by the water softener 103 through the sensor 104 after performing the regeneration operation on the water softening substance, and determine the operation state of the water softener 103 according to the hardness of the water until it is determined that the hardness value of the water in the water softener 103 is less than the first hardness threshold or the second hardness threshold.

If the replacement substance is not missing, the regeneration operation command is generated again until the hardness value of the water in the water softener 103 is smaller than the first hardness threshold value or the second hardness threshold value in step S804.

In the case where the processing module 101 determines that the replacement material is not missing based on the above steps, it may be determined that the regeneration effect of the water softener 103 is not good due to the insufficient number of regeneration operations, and it may be configured to generate the regeneration operation command again and instruct or control the regeneration operation mode to be entered, or control the relevant device or the like to perform the corresponding regeneration operation.

Here, the processing module 101 needs to determine the regeneration effect of the water softener 103 after each regeneration operation, and if the regeneration effect is not expected and the replacement substance is not absent, continue to control the regeneration operation until it is determined that the hardness value of the water in the water softener 103 is less than the first hardness threshold value or the second hardness threshold value, and stop controlling the regeneration operation.

Here, there is also a case where the processing module 101 has not yet achieved the intended effect of the softening effect of the water softener 103 after the control has performed the plurality of regeneration operations, and then the occurrence of this case, which means that the softening effect of the water softener 103 has not been ensured by the regeneration operation, requires the execution of the flow steps as shown in fig. 9:

Step S901, when the number of times of performing the regenerating operation on the water softener 103 reaches a number threshold, obtaining a fourth hardness value of the water in the water softener 103;

the frequency threshold may be determined by experience, history data, experiment, etc., and is not limited in this application, and is, for example, 3, 4, 5, etc.

The processing module 101 may determine the number of times the regeneration operation is performed based on a counter provided thereon, may determine the number of times the regeneration operation is performed based on a record of the execution of the regeneration operation, and the like, which is not limited in this application.

Here, the number of times the processing module 101 counts the regeneration operation may be counted in month units or in year units, which is not limited in this application. For example, the processing module 101 may count the number of regeneration operations performed in 1 year, compare the number of regeneration operations with a threshold number of times, and if the number of regeneration operations has reached the threshold number of times, continuously determine whether the softening effect of the water softener 103 reaches the expected value according to the hardness value of the water softened by the water softener 103 after the last regeneration operation.

The processing module 101 may continuously determine the fourth hardness value of the water in the water softener 103 according to the concentration data transmitted by the sensor 104 disposed in the washing cycle water path, and the method for determining the hardness of the water is described above, which is not repeated herein.

In step S902, if the fourth hardness value is greater than the first hardness threshold value or the second hardness threshold value, a replacement message for prompting replacement of the water softening substance in the water softener 103 is generated.

Wherein, the processing module 101 may send a replacement message to the user's terminal device after determining that the first hardness value is still greater than the first hardness threshold value or the second hardness threshold value, so that the user timely knows that the water softening substance in the water softener 103 should be replaced.
