The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

Based on the potential safety hazard problem of clothes treatment equipment in the related art, such as a washing machine, a washing and drying integrated machine and the like, the embodiment of the application provides a control method applied to the clothes treatment equipment. The method provided by the embodiment of the present application can be implemented by a computer program, and when the computer program is executed, each step in the control method provided by the embodiment of the present application is completed. In some embodiments, the computer program may be executed by a control device in a laundry treatment apparatus. Fig. 1 is a schematic flow chart of an implementation of a control method provided in an embodiment of the present application, and is applied to a clothes treatment apparatus. As shown in fig. 1, the control method includes the steps of:

step S101, controlling the clothes processing equipment to execute a dehydration program under the condition that the water level in the barrel body of the clothes processing equipment is higher than a first water level threshold value and the duration time reaches a first time threshold value.

The control method of the embodiment of the application is applied to clothes treatment equipment, in particular to clothes treatment equipment with a water retaining function, such as household appliances like washing machines and washing and drying integrated machines. In the embodiment of the present application, a laundry treatment apparatus is taken as an example of a washing machine.

In practical application, the water retaining function is selected when a user washes clothes, or more water is remained in the washing machine barrel due to other reasons (such as drain valve faults), and if the user does not discharge the remained water in time, the water level detection device is always in a high-pressure state, so that the precision of the water level sensor is influenced. In order to avoid that the water level detection device is in a high-pressure state for a long time, in the embodiment of the application, when the water level in the washing machine is higher than a first water level threshold and the duration time reaches a first time threshold, the washing machine is controlled to start to execute a dehydration program. When the dewatering program is executed, the drainage valve is controlled to be opened to drain water, and dewatering is carried out after the drainage is finished.

After the dewatering program is executed and completed, residual water in the barrel body of the washing machine is completely discharged, and only washing clothes are left in the barrel body, so that the water level detection device is no longer in a high-pressure state, the condition that the washing machine is soaked in water for a long time to damage the clothes and even the residual water is deteriorated is avoided, and meanwhile, the mechanical fault of the washing machine caused by the long-time water can be avoided, the water level detection device is not in the high-pressure state for a long time, and the accuracy of a water level value detected by the water level detection device is ensured.

In the embodiment of the application, the water level detection device can be a water level sensor and can also be other devices capable of detecting water quantity.

Through step S101, although the water level detection apparatus is no longer in a high pressure state, it is still in a high pressure state until then, and the accuracy of the water level detection apparatus may have been affected. In order to ensure the accuracy of the water level value detected by the water level detecting device, after the dehydration process is completed, the determining step is continuously performed to determine whether the water level detecting device is in a normal state.

And S102, determining water filling parameters according to the weight of the clothes to be treated in the barrel.

The weight of the laundry to be treated is the weight of the laundry to be treated after dehydration.

Here, the washing machine may acquire the weight of the laundry dehydrated in the tub by a built-in weight detecting device (e.g., a weight sensor), or may acquire the weight of the laundry dehydrated in the tub by a fuzzy weighing method, and then determine the water filling parameter according to the weight of the laundry. The fuzzy weighing principle comprises the following steps: after a start key of the washing machine is pressed, the motor starts to rotate, resistance exists between the barrel body and clothes due to contact friction, the weight of the clothes is in direct proportion to the resistance, the resistance is larger when the clothes are more, and then the weight of the clothes is roughly judged by judging current from the clutch to the motor.

In one implementation, the water filling parameter may be a water filling time, and the water filling time is determined according to the weight of the laundry to be treated in the tub, and may be implemented as: determining the volume of the clothes to be treated according to the weight of the clothes to be treated in the barrel, determining the water quantity to be injected according to the water level reference value and the volume of the clothes to be treated, and calculating the water injection duration according to the water quantity to be injected and the water injection speed.

In another implementation manner, the water filling parameter may be a water filling level value, and the water filling level value is determined according to the weight of the laundry to be treated in the tub, and may be implemented as follows: the volume of the clothes to be treated is determined according to the weight of the clothes to be treated in the barrel, the water filling amount is calculated according to the preset water filling duration and the water filling speed, and the water filling level value is calculated according to the water filling amount and the volume of the clothes to be treated.

Step S103, determining the state of the water level detection device of the clothes treatment equipment based on the water filling parameter.

The states of the water level detection apparatus include an abnormal state and a normal state. After water is injected into the barrel body based on water injection parameters, a water level measuring value is detected by using a water level detecting device, the water level measuring value is compared with a water level reference value, and if water is left for a long time without influencing the precision of the water level detecting device, the difference between the water level detecting value and the water level reference value is smaller; if the accuracy of the water level detection device is affected by the long-time water retention, the difference between the water level detection value and the water level reference value is large, and therefore the state of the water level detection device is determined.

The principle of measuring water level by a water level sensor in the washing machine is as follows: the washing machine is internally provided with a plastic pipe, the top end of the pipe is a pressure sensor, a U-shaped pipe is arranged between the plastic pipe and the washing bucket, when the washing machine is filled with water, the water level in the bucket body rises, the water level in the plastic pipe also rises, air in the plastic pipe is compressed, the pressure sensor detects the air pressure value in the pipe, and the water level is measured through the size of the pressure value. When the pressure sensor measures the pressure value, the water level frequency value is actually measured, namely when the water level sensor detects the water level measurement value, the water level frequency measurement value is actually measured, and the water level frequency measurement value is compared with the water level frequency reference value at the same water level to determine whether the precision of the water level sensor is normal or not.

The control method provided by the embodiment of the application comprises the following steps: controlling the clothes treatment equipment to execute a dehydration program under the condition that the water level in a barrel body of the clothes treatment equipment is higher than a first water level threshold value and the duration time reaches a first time threshold value; determining water injection parameters according to the weight of the clothes to be treated in the barrel, wherein the weight is the weight of the clothes to be treated after dehydration; the state of the water level detection device of the laundry treating apparatus is determined based on the water filling parameter, and the state includes an abnormal state and a normal state. In this way, when the user does not discharge the residual water in the barrel of the clothes treatment equipment for a long time, the clothes treatment equipment is controlled to automatically execute the dehydration program, so that the clothes are not soaked in the water for a long time, and the water level sensor is not always in a high-pressure state; and after the dehydration program is finished, determining water filling parameters according to the weight of the clothes in the barrel body, and determining whether the precision of the water level detection device is normal according to the water filling parameters, so that the water level detection device is repaired when the water level detection device is abnormal, and the detection precision of the water level detection device is ensured.

In some embodiments, the step S102 "determining the water filling parameter according to the weight of the laundry to be treated in the tub" in the embodiment shown in fig. 1 can be implemented by the following steps:

step S1021, acquiring the water filling speed of the clothes treatment equipment and the weight of the clothes to be treated in the barrel body.

The water filling rate may be the amount of water filled into the tub of the washing machine in a unit time, for example, the unit time is per minute, and the physical unit of the water filling rate is L/min (liters per minute); the fill rate may also be the length of time required to fill a unit volume of water, such as liters per unit volume, where the fill rate is in physical units of min/L (minutes per liter).

Here, the weight of the laundry to be treated is the weight of the laundry to be treated after dehydration. The washing machine can acquire the weight of the clothes dehydrated in the barrel body through a fuzzy weighing method, and then determine water filling parameters according to the weight of the clothes. The fuzzy weighing principle comprises the following steps: after a start key of the washing machine is pressed, the motor starts to rotate, resistance exists between the barrel body and clothes due to contact friction, the weight of the clothes is in direct proportion to the resistance, the resistance is larger when the clothes are more, and then the weight of the clothes is roughly judged by judging current from the clutch to the motor.

In step S1022, the volume of the laundry to be treated is determined based on the first relation table and the weight stored in advance.

The first relation table stores the corresponding relation between the weight and the volume of the clothes to be processed. The storage space of the washing machine is stored with a first relation table, the first relation table is a corresponding relation between the weight and the volume of the clothes measured according to a large amount of laboratory data, and the approximate volume of the clothes can be obtained by inquiring the first relation table according to the weight.

And S1023, determining the water injection time required for injecting water to a preset water level reference value according to the water injection speed and the volume.

Here, the water level reference value may be determined according to the capacity of the tub of the washing machine, and generally, the more the amount of water, the smaller the error of the water level detecting device, and thus, the water level reference value may be set to the maximum capacity of the washing machine, which is denoted as C1 in the embodiment of the present application.

The water filling speed obtained in the step S1021 is recorded as V, the volume of the laundry determined in the step S1022 is recorded as C2, and the water filling time period T1 is calculated according to the water filling speed V, the volume C2 and the water level reference value C1. When the water injection speed V represents the time length required for injecting water with unit volume, the water injection time length T1 is (C1-C2) multiplied by V; when the water injection speed V represents the amount of water injected per unit time, the water injection time period T1 is (C1-C2) ÷ V.

And step S1024, determining water injection duration as a water injection parameter.

When the quantity of the clothes in the barrel body is large, the volume of the clothes is large, and the time for injecting water to reach the water level reference value is short; when the quantity of the clothes in the barrel body is small, the volume of the clothes is small, and the time required for filling water to the water level reference value is long.

In some embodiments, the water filling rate of the clothes treating apparatus obtained in step S1021 may be obtained from a storage space of the clothes treating apparatus, and the water filling rate may be a default value or an actual measurement value. One way to actually measure the water injection rate is:

and S001, responding to an operation instruction for triggering execution of a barrel self-cleaning program, and controlling a water injection device of the clothes treatment equipment to be opened for water injection.

Here, when the washing machine performs the tub self-cleaning process, there is no laundry in the tub and only water exists in the tub. And when the washing machine executes the tub self-cleaning program, the water level detecting device is in a normal state, and the detected water level measurement value is within the measurement error range.

And S002, detecting that the water level in the barrel body rises to a preset water level reference value, and controlling the water injection device to be closed.

Here, the water level reference value may be determined according to the capacity of the tub of the washing machine, and generally, the more the amount of water, the smaller the error of the water level detecting device, and thus, the water level reference value may be set to the maximum capacity C1 of the washing machine in the embodiment of the present application.

And S003, acquiring a first starting time of the water injection device.

The first starting time of the water injection device is the time of injecting water into the barrel body, namely the time required for injecting water to the water level reference value.

And step S004, determining the water injection speed according to the first opening time and the water level reference value.

In one implementation, the quotient of the first opening time and the water level reference value may be determined as the water filling speed, such as calculating the water filling speed V according to the first starting time T2 and the water level reference value C1. When the water injection speed V represents the time length required for injecting unit volume of water, V is T2 ÷ C1; when the water injection rate V characterizes the amount of water injected per unit time, V ═ C1 ÷ T2.

In another implementation, for more accurate measurement of the water injection rate, multiple measurements may be taken, and the average of the multiple measurements is determined as the water injection rate. Taking the example of determining the water injection rate by two measurements, the step S004 can be implemented as the following steps: controlling the clothes treatment equipment to operate a barrel self-cleaning stage, wherein the barrel self-cleaning stage at least comprises a washing process and a drainage process; after the operation of the self-cleaning stage of the barrel is determined to be finished, controlling the water injection device to be started again to inject water; detecting that the water level in the barrel body rises to a preset water level reference value, controlling the water injection device to be closed, and acquiring second opening time for opening the water injection device again; and determining the water injection speed according to the first opening time length, the second opening time length and the water level reference value.

In this implementation manner, a quotient of the first opening duration and the water level reference value may be used as a first speed obtained by the first measurement, a quotient of the second opening duration and the water level reference value may be used as a second speed obtained by the second measurement, and an average value of the first speed and the second speed may be determined as the water injection speed.

The water filling rate V is calculated as a function of the first start time period T2, the second opening time period T3, and the water level reference value C1. When the water injection velocity V characterizes the time required to inject a unit volume of water, V ═ V (T2 ÷ C1+ T3 ÷ C1) ÷ 2 ═ T2+ T3 ÷ C1 ÷ 2; when the water injection rate V characterizes the amount of water injected per unit time, V ═ C1 ÷ T2+ C1 ÷ T3) ÷ 2.

Step S005 of storing the water filling rate into the storage space of the laundry treating apparatus.

After the water filling speed is actually measured, the water filling speed is stored in the storage space of the washing machine, so that the water filling speed can be acquired from the storage space when the water level detection device is automatically repaired later. Here, in the storage, the default value of the water filling rate stored in the storage space may be replaced with the actual measurement value, or the default value of the water filling rate and the actual measurement value may be stored at the same time.

In the embodiment of the application, the water injection speed is determined when the washing machine executes the self-cleaning program of the barrel, so that the error of the volume of clothes can be eliminated, and the accurate measurement of the water injection speed is realized. And when the water injection speed is determined, the self-cleaning program of the barrel can be executed for many times, the average value of the determined water injection speeds is used as the water injection speed, objective special conditions such as low water pressure and the like are eliminated, and the measured water injection speed is more accurate.

In some embodiments, when the water filling parameter is water filling duration, the step S103 "determining the state of the water level detecting means of the laundry treating apparatus based on the water filling parameter" in the embodiment shown in fig. 1 can be implemented by:

and a step S1031 of controlling the laundry treating apparatus to perform a water supply process based on the water supply time period.

After the water filling procedure is performed based on the water filling parameter, the water level in the tub is a water level reference value, which is an actual value.

Step S1032 is to detect the water level in the tub by the water level detecting device to obtain a water level measurement value.

The water level inside the tub is detected by a water level detecting device to obtain a water level measurement value, which is a measurement value, which is actually a water level frequency value in hertz (Hz).

And step S1033, acquiring a water level deviation value according to the water level measured value and a preset water level reference value.

Recording the water level frequency measurement value corresponding to the water level measurement value as A, and inquiring the water level frequency reference value corresponding to the water level reference value C1 from the memory space to obtain a water level deviation value D (A-B), wherein | represents an absolute value, by calculating the water level frequency reference value corresponding to the water level reference value C1 as B. The water level measurement value is lower than the water level reference value or higher than the water level reference value, and the water level is deviated.

Step S1034, whether the water level deviation value is larger than a preset deviation threshold value is judged.

When the water level deviation value is greater than the preset deviation threshold value, it indicates that the difference between the water level measurement value detected by the water level detection device and the actual water level reference value is large, and at this time, the water level detection device is considered to be abnormal, and the process goes to step S1035; when the water level deviation value is less than or equal to the preset deviation threshold value, it indicates that the difference between the detected water level value detected by the water level detection device and the actual water level reference value is not large, and at this time, the water level detection precision is considered to be within the normal range, and the process proceeds to step S1036.

In the embodiment of the present application, the preset deviation threshold may be set according to the type of the laundry processing apparatus and the precision requirement, for example, may be set to any value between 30Hz and 60Hz, such as 50 Hz. When D > 50Hz, go to step S1035; when D is less than or equal to 50Hz, the process goes to step S1036.

In step S1035, the state of the water level detection apparatus is determined to be an abnormal state.

In step S1036, it is determined that the state of the water level detecting apparatus is a normal state.

In the embodiment of the application, the state of the water level detection device is determined through the water injection parameters, and the automatic judgment of the state of the water level detection device is realized, so that the automatic repair of the water level detection device can be realized without user operation.

In some embodiments, after determining the state of the water level detection device in step S103, the method may further include a repairing step S104 of repairing the water level detection device in case that the state of the water level detection device is an abnormal state. And when the accuracy that the water level detection device is influenced by the long-time water retention is determined, controlling the washing machine to carry out automatic repair.

In one implementation, the "repairing the water level detection device" in step S104 may be implemented by:

step S1041, controlling the laundry treating apparatus to enter a rinsing process.

The water level sensor is always in a high-pressure state in the long-time water retaining process, the water level in the plastic pipe is higher than the water level in the barrel body, and the water level in the plastic pipe and the water level in the barrel body are rebalanced in the rinsing process in a vibration mode and the like, so that the automatic repair of the water level sensor is realized.

Step S1042, the rinsing duration is monitored.

Step S1043, determining whether the rinsing duration reaches a second duration threshold.

When the rinsing time reaches the second time threshold, the water level in the plastic pipe and the water level in the barrel body are considered to be balanced again, and then the step S1044 is executed; when the rinsing time does not reach the second time threshold, the water level in the plastic pipe and the water level in the barrel body are not balanced, and the step S1042 is returned to obtain the rinsing time again.

In this embodiment of the application, the second duration threshold may be preset by a user, or may be a default value. The second duration threshold value may be any value between 30s (seconds) and 3min (minutes), for example, 60 s.

In step S1044, the laundry treating apparatus is controlled to perform the dehydration process.

And after rinsing for a second time threshold, controlling the washing machine to drain water and dewater, and determining that the water level detection device finishes an automatic repair process.

In some embodiments, the laundry to be treated in the tub may be entangled and stacked together before the dehydration process is performed, and if the dehydration process is directly performed, the tub may be bumped due to a load imbalance. Based on this, in the embodiment of the application, before the dehydration program is executed, the clothes in the barrel body can be shaken to balance the gravity center of the clothes, so that the barrel collision frequency is reduced. In one implementation, shaking away the underwear in the barrel body can be realized through the following steps:

step S11, the laundry treating apparatus is controlled to enter a washing process.

In step S12, the first washing duration is monitored.

In step S13, it is determined whether the first washing duration reaches the third duration threshold.

When the first washing time period reaches the third time period threshold value, it is considered that the laundry in the washing machine is shaken, and then, the process proceeds to step S14; when the first washing time period does not reach the third time period threshold, it is determined that the laundry in the washing machine is not shaken, and at this time, the washing is continued, and the step S12 is returned to acquire the first washing time period again.

In this embodiment of the application, the third duration threshold may be preset by a user, or may be a default value. The third duration threshold may take any value between 30s and 3min, for example, take 60 s.

And step S14, controlling the laundry treating apparatus to stop the washing process.

After the third time threshold value is used for washing, the fact that the clothes in the barrel body are shaken up is determined, at the moment, the washing machine is controlled to drain water and dewater, and the number of times of collision of the barrel body can be reduced.

In practical application, if the staving internal water is when more, the clothing floats on water, and after washing was long for the time, trembled the effect and probably not good, can partly discharge the staving internal water this moment, wash again and tremble the scattering.

When implemented, after the above step S14, the following steps are continuously performed:

and step S15, controlling the drainage device of the clothes processing equipment to be opened for drainage.

And step S16, detecting that the water level in the barrel body drops to a second water level threshold value, and controlling the drainage device to be closed.

The second water level threshold is lower than the water level reference value.

Step S17, the laundry treating apparatus is controlled to enter a washing process.

After the water in the barrel body of the washing machine is discharged to a low water level, the washing process is carried out again, and the clothes in the barrel body are shaken and dispersed continuously.

In step S18, the second washing period is monitored.

In step S19, it is determined whether the second washing time period reaches the fourth time period threshold.

When the second washing time period reaches the fourth time period threshold value, it is considered that the laundry in the washing machine is sufficiently shaken, and then, the flow proceeds to step S20; when the second washing time period does not reach the fourth time period threshold, it is determined that the laundry in the washing machine is not shaken out sufficiently, and at this time, the washing is continued, and the step S18 is returned to acquire the second washing time period again.

In this embodiment of the application, the fourth time threshold may be preset by a user, or may be a default value. The fourth time threshold value may be any value between 15s and 1min, for example, 30 s.

And step S20, controlling the laundry treating apparatus to stop the washing process.

In the embodiment of the application, before the dehydration, control washing machine twice gets into the washing process, can make the internal clothing of staving fully tremble and scatter, reduces the number of times that the staving bumps.

Based on the method shown in fig. 1, an embodiment of the present application further provides a control method for repairing a water level detection device. Fig. 2 is a schematic flow chart of another implementation of the control method provided in the embodiment of the present application, and as shown in fig. 2, the method includes the following steps:

step S201, under the condition that the water level in the barrel body of the clothes treatment equipment is determined to be higher than a first water level threshold value, the duration of the water level higher than the first water level threshold value is obtained.

In order to avoid that the water level detection device is in a high-pressure state for a long time, in the embodiment of the present application, when the water level in the washing machine is higher than the first water level threshold, the duration of the water level higher than the first water level threshold is obtained.

The first water level threshold may be the lowest water level, i.e. the duration is obtained when water is detected in the tub.

Step S202, judging whether the duration of the water level higher than the first water level threshold reaches a first time threshold.

When the duration of the water level higher than the first water level threshold reaches the first time threshold, determining to start a water retention protection function, and avoiding the residual water from being stored in the barrel body all the time, and then entering step S203; and returning to the step S201 to continue water retention when the duration of the water level higher than the first water level threshold does not reach the first time threshold.

Step S203, controlling the laundry treating apparatus to perform a dehydration process.

In the embodiment of the application, when the water level in the washing machine is higher than the first water level threshold and the duration time reaches the first duration threshold, the washing machine is controlled to start to execute the dehydration program. When the dewatering program is executed, the drainage valve is controlled to be opened to drain water, and dewatering is carried out after the drainage is finished.

Step S204, determining water filling parameters according to the weight of the clothes to be processed in the barrel body.

Here, the weight of the laundry to be treated is the weight of the laundry to be treated after dehydration.

Here, the washing machine may acquire the weight of the laundry, which has been dehydrated in the tub, through a fuzzy weighing method, and then determine a water filling parameter according to the weight of the laundry.

Step S205, determining the state of the water level detection device of the clothes treatment apparatus based on the water filling parameter.

In step S206, it is determined whether the state of the water level detection device is abnormal.

When the state of the water level detection device is abnormal, the water level detection device needs to be repaired, and the process goes to step S207; when the state of the water level detection apparatus is normal, the water level detection apparatus does not need to be repaired, and the process proceeds to step S210.

And step S207, repairing the water level detection device.

For an implementation manner of repairing the water level detection device, refer to step S1041 to step S1044.

In step S208, the number of times of repairing the water level detection device is acquired.

The number of repairs is increased by 1 every time the automatic repair process is completed, i.e., every time step S207 is performed.

Step S209, determine whether the repair time is less than a preset threshold.

When the repairing times are smaller than the preset threshold value, returning to the step S205, and determining the state of the repaired water level detection device based on the water injection parameters; when the number of times of repair reaches the preset threshold, whether the abnormality of the water level detection apparatus has been repaired or not, the repair is considered to be completed, and then the process proceeds to step S210.

In another implementation manner, when the repair frequency reaches the preset threshold, returning to step S205, determining the state of the water level detection device after performing the repair for the preset threshold again based on the water injection parameter, and when the state of the water level detection device is still an abnormal state, controlling the alarm device to output a prompt message that the water level detection device has a fault to prompt a user to perform maintenance in time, and then entering step S210; when the state of the water level detection apparatus is normal, which indicates that the state of the water level detection apparatus is restored to normal after the last repair, the process proceeds to step S210.

In the embodiment of the present application, the preset threshold may be preset by a user, or may be a default value. The preset threshold value can be any value of 3, 5, 10 and the like, for example, 3, and after 3 times of automatic repair, the repair is considered to be completed no matter whether the state of the water level detection device is repaired to a normal state or not.

Step S210, controlling the laundry treating apparatus to perform a dehydration process.

According to the method provided by the embodiment of the application, when a user does not discharge the residual water in the barrel of the clothes treatment equipment for a long time, the clothes treatment equipment is controlled to automatically execute a dehydration program, so that the clothes are not soaked in the water for a long time, and the water level sensor is not always in a high-pressure state; and after the dehydration program is finished, determining water injection parameters according to the weight of clothes in the barrel body, determining whether the state of the water level detection device is normal or not according to the water injection parameters, automatically repairing the water level detection device when the state of the water level detection device is abnormal, and continuing repairing if the repair frequency is smaller than a preset threshold value and if the water level detection device is still in the abnormal state until the water level detection device is restored to the normal state or the repair frequency reaches the preset threshold value, and further ensuring the detection precision of the water level detection device.

Next, an exemplary application of the embodiment of the present application in a practical application scenario will be described.

Among the current technical scheme, to the control mode of washing machine's the protection of remaining water, constantly acquire latency through the current water that remains, the user can start the drainage function in latency, and after the latency, then automatic drainage improves the laundry efficiency. However, in the related art, in order to improve the clothes washing experience after water retention and accelerate the clothes washing efficiency, the following two points are not considered: 1) the damage to the washing machine itself after water is left in the washing machine due to the water retention function or other reasons; 2) after long-time water retention, the water is directly drained, and the barrel collision frequency is increased due to no swinging process. The long-time water retention may cause the increase of the failure alarm times of the washing machine, seriously affect the use experience of users and even cause the permanent failure of the washing machine.

Based on the above problem, an embodiment of the present application provides a method for controlling water retention protection of a washing machine, and fig. 3 is a schematic diagram of an implementation flow of the method for controlling water retention protection provided by the embodiment of the present application, as shown in fig. 3, the method includes the following steps:

in step S301, a large amount of residual water is left in the washing machine due to water retention, suspension, or other reasons.

Step S302, judging whether the water retention time reaches 24 hours or not under the normal state of the washing machine.

When it is reached, the process proceeds to step S303; if not, the process returns to step S301.

And step S303, carrying out balance washing for 60S, draining to 4 grades, carrying out balance washing for 30S, and emptying for dehydration.

And step S304, weighing the wet cloth to obtain a wet cloth pulse value P1.

In step S305, the 8-stage water intake time T1 is calculated to be T1 (C1-C2).

Wherein: t1 is the water inlet time per liter of water (corresponding to the water injection speed V in the above); c1 is water capacity L of 8 steps (according to actual capacity of washing machine); c2 is the capacity L occupied by laundry obtained from the wet cloth weight value P1 (C2 is proportional to P1).

And S306, reading the current water level frequency value H1 when water enters 8 grades according to the water inlet time T1.

In step S307, it is determined whether the water level sensor has failed.

When a failure occurs, the process proceeds to step S309, and when a failure does not occur, the process proceeds to step S308.

And step S308, carrying out balance washing for 60S, draining to 4 grades, carrying out balance washing for 30S, and emptying for dehydration.

And step S309, rinsing for 1 minute, carrying out balanced washing for 60S, draining to 4 grades, carrying out balanced washing for 30S, and emptying for dewatering.

In step S310, whether dehydration is achieved 3 times or not is judged.

When 3 times, go to step S311; if not, the process returns to step S306.

Step S311 ends.

And judging whether to start the water retention protection function or not according to the water retention duration of the washing machine. Whether the water level sensor fails or not is judged by presetting water inlet time and a water level frequency value, and the working performance of the water level sensor can be effectively recovered by multiple times of water inlet dehydration; meanwhile, the clothes are downshifted and leveled in the draining process with the water retention protection function, so that the blockage of a draining pump and a draining valve can be effectively reduced, and the failure frequency of the washing machine is reduced; on the other hand can effectively reduce and hit the bucket probability, both can improve user's laundry and experience and reduce complaining, also can guarantee simultaneously that washing machine has good operating mode.

And (5) running detection in a water retention state.

2) Firstly, judging whether the washing machine is in a normal state (the door is closed and no alarm is given), if so, judging whether water is left for 24h (hours), and if the water is left for more than 24h, operating downshift and leveling; after dehydration, wet cloth is weighed, a pulse value P1 is reserved, and the water inlet time required by 8 grades of water is calculated; after water enters 8 grades according to the water inlet time T1, reading the current water level frequency value H1, and then judging whether the water level sensor is in fault; if the fault occurs, downshifting and leveling and dehydration are performed 3 times.

3) The water inlet time estimation principle is as follows: weighing wet cloths (corresponding to the clothes to be treated in the above) by fuzzy weighing, wherein weighing data is P1 (corresponding to the weight of the clothes to be treated in the above), making a curve of the weighing data P1 and the capacity C2 (corresponding to the volume of the clothes to be treated in the above) occupied by the wet cloths according to a large amount of laboratory data, obtaining C2 by a table look-up method according to a P1 value, and calculating 8-grade water inlet time T1-T1 (C1-C2) by water inlet time T1 (estimated value at the beginning and actual value of a user washing machine after one-time barrel self-cleaning is executed) and C1 (constant value is determined according to the capacity of the barrel).

4) Judging whether the water level sensor has a fault principle: and according to the fixed water inlet time, after water enters to 8 grades, measuring the water level frequency value A (corresponding to the water level frequency measured value in the previous step), and if the water level frequency value | A-2170| is more than 50, judging that the water level sensor is in fault. (data are specific model values for reference.)

Water level (Standard)	Frequency (KHz) (corresponding to the above water level frequency reference)
		First gear	25.00
Second gear	24.50
		Third gear	24.10
Fourth gear	23.60
		Fifth gear	23.20
Sixth gear	22.70
		Seventh gear	22.20
Eighth gear	21.70

And S404, water is fed to the 8 th gear, and the opening time T3 of the water inlet valve is recorded.

In step S405, the required water intake time temp _ t for 1 liter of water is calculated.

Wherein: temp _ T1 ═ T2+ T3)/2C 1; the unit of time is seconds(s). Overriding the default value t1 in the memory space.

Step S406, washing-draining-dehydrating.

Step S407 ends.

1) The evaluation is performed when the user performs the bucket self-cleaning procedure.

2) Since the washing machine is empty and the water inlet amount to the 8 th level is fixed, such as C1, when the self-cleaning program is executed, the water inlet time per unit water amount can be estimated by recording the opening time of the water inlet valve from the water inlet to the 8 th level.
