The terminology used herein is for the purpose of describing embodiments of the 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, a dish washer 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 application can be realized by a computer program, and each step in the control method provided by the embodiment of the application is completed when the computer program is executed. In some embodiments, the computer program may be executed by a control device in the laundry treatment apparatus. Fig. 1 is a schematic flow chart of an implementation of a control method according to an embodiment of the present application, which is applied to a laundry treatment apparatus. As shown in fig. 1, the control method includes the steps of:

Step S101, determining that the laundry treating apparatus is in a non-operating state, and acquiring a first water level in a tub of the laundry treating apparatus.

The control method of the embodiment of the application is applied to the household appliances such as a washing machine, a washing and drying integrated machine, a dish washer and the like. The laundry treating apparatus will be described below as an example of a washing machine.

In practical applications, when the washing machine is in a non-working state, i.e. a standby state or a shutdown state, the water inlet device of the washing machine may malfunction, resulting in more than water inlet. Here, when the user presses the "power" button on the control panel of the washing machine, the washing machine is in a standby state, and when the user does not press the "power" button, or presses the "power" button again in the standby state, the washing machine is in a shutdown state, and the control device of the washing machine is powered on. The washing machine is in a power-off state different from a power-off state.

When the washing machine is in a non-working state and the water level in the barrel exceeds the height of the lowest point of the door body, if the door body is in an open state, water overflows from the barrel body and flows to the ground, articles in the home are damaged slightly, economic loss is caused, and safety accidents such as electric shock and the like can be caused if the door body is heavy. In order to solve the problem in the related art, a water level sensor detects the water level in the barrel body, judges whether the water level in the barrel body exceeds the lowest point of the door body, and if so, opens a drain valve to drain. Although the related art can prevent water from overflowing from the door body to some extent, when some malfunction occurs in the water level sensor, the water level sensor can detect the water level parameter value, but the detected water level parameter value may deviate from the actual value. For example, when water remains in the barrel for a long time, the accuracy of the air pressure sensor is deviated, or the accuracy of the crystal oscillation frequency of the chip is deviated, or the accuracy of the air pressure sensor is deviated due to the influence of the ambient temperature on the atmospheric pressure, the detected water level parameter value is smaller than the actual value, that is, the actual water level is already beyond the lowest point of the door body, but the water level parameter detected by the water level sensor does not reach the water level parameter corresponding to the water level at the lowest point of the door body, so that water overflows from the barrel body.

In order to solve the problem that in the related art, accuracy deviation occurs in a water level sensor and a chip crystal oscillator frequency, and water in a barrel overflows due to the influence of ambient temperature, in the embodiment of the application, when the clothes treatment equipment is determined to be in a non-working state, a water level detection device is controlled to detect a first water level parameter in the barrel, and the first water level is obtained based on the first water level parameter.

In one implementation, the water level detecting device may be a water level sensor, such as an air pressure sensor, where the obtaining the first water level by using the first water level parameter detected by the water level detecting device may be implemented as: the water level sensor senses a first water level frequency value based on the pressure of water, sends the first water level frequency value to a control device of the clothes treatment equipment, and the control device inquires a corresponding water level in a first relation table stored in a storage space of the clothes treatment equipment in advance based on the first water level frequency value to obtain a first water level, wherein the first relation table comprises the water level frequency value and the water level with corresponding relation.

In another implementation, the water level detecting device may be a weight sensor, and the acquiring the first water level by using the first water level parameter detected by the water level detecting device may be implemented as: the weight sensor senses a first water level weight value based on the gravity of water, sends the first water level weight value to a control device of the clothes treatment equipment, and queries a corresponding water level in a second relation table stored in a storage space of the clothes treatment equipment in advance based on the first water level weight value to obtain a first water level, wherein the second relation table comprises the water level weight value and the water level with corresponding relation.

Step S102, under the condition that the first water level is higher than the preset water level threshold value, obtaining the second water level in the barrel body.

After the first water level is obtained in step S101, it is determined whether the first water level is higher than a preset water level threshold, so as to determine whether water exists in the tub. When the first water level is determined to be higher than the preset water level threshold, water is considered to exist in the barrel body, and the water level detection device is controlled again to detect a second water level parameter in the barrel body to obtain a second water level. And determining whether the water level in the barrel body changes or not by comparing the water levels in the barrel body at different moments, namely comparing the first water level and the second water level.

In the embodiment of the application, the preset water level threshold value may be the lowest water level at which the water level detection device can detect that water exists in the barrel body; or a preset lower water level, such as a preset heating protection water level according to the position of the heating pipe; and the water level can be any water level which is not higher than the lowest point of the door body.

Step S103, in the case that the laundry treatment apparatus is determined to be faulty based on the first water level and the second water level, the water draining device of the laundry treatment apparatus is controlled to be opened to drain water in the tub.

If the washing machine is in a non-working state and the washing machine does not have water inlet failure and water outlet failure, the water level in the barrel body is unchanged, and the first water level and the second water level obtained twice are the same; if the washing machine has water inlet faults (such as a water inlet valve faults), the water level in the barrel body rises due to water inlet, and the second water level acquired for the second time is higher than the first water level acquired for the first time; if the washing machine has a drainage failure (such as a drainage valve failure), the water level in the barrel body is reduced due to the drainage, and the second water level acquired for the second time is lower than the first water level acquired for the first time. Based on the above, in the embodiment of the application, after the first water level and the second water level are obtained, whether the water level in the barrel body changes or not is determined by comparing the water levels at different moments, and when the water level in the barrel body changes, the laundry treatment equipment is determined to be faulty.

Since the control means is energized when the laundry treating apparatus is in the non-operating state, other means of the laundry treating apparatus can be controlled to operate. When the clothes treatment equipment is determined to be faulty, the water draining device is controlled to be started, water in the barrel body is drained, and water in the barrel body can be prevented from overflowing. The drain device may be a drain valve.

In the embodiment of the present application, if the water inlet device and the water outlet device of the laundry treatment apparatus do not fail, even if the water level detecting device fails, the deviation values of the two measurements are equal, that is, the deviation between the actual value of the first water level and the measured value of the first water level obtained at the first time is equal to the deviation between the actual value of the second water level and the measured value of the second water level obtained at the second time. Under the same environment, when the water level detection device is unchanged, the precision deviation is unchanged, the first water level and the second water level are compared, and the comparison is equivalent to the comparison of the actual value of the water level at the first moment and the actual value of the water level at the second moment, so that the deviation can be counteracted, and the problem that water in the barrel is prevented from overflowing when the water level detection device is deviated is solved.

According to the control method provided by the embodiment of the application, when the clothes treatment equipment is determined to be in a non-working state, a first water level in a barrel body of the clothes treatment equipment is obtained; under the condition that the first water level is higher than a preset water level threshold value, obtaining a second water level in the barrel body; in case that the laundry treating apparatus is determined to be malfunctioning based on the first water level and the second water level, a drain device of the laundry treating apparatus is controlled to be opened to drain water in the tub. Therefore, when the first water level is higher than the preset water level threshold value, the water exists in the barrel body, whether the clothes treatment equipment breaks down or not can be determined as early as possible by comparing the change conditions of the first water level and the second water level, the water draining device is started immediately when the occurrence of the faults is determined, the water in the barrel body is drained in time, the occurrence probability of water leakage faults can be reduced as much as possible, potential safety hazards are eliminated, and the safety of using the clothes treatment equipment is improved.

On the basis of the embodiment shown in fig. 1, the embodiment of the present application further provides a control method applied to a laundry treatment apparatus, and fig. 2 is a schematic flow chart of another implementation of the control method provided by the embodiment of the present application, as shown in fig. 2, where the control method includes the following steps:

step S201, determining that the laundry treating apparatus is in a non-operating state, and acquiring a first water level in a tub of the laundry treating apparatus.

Here, the first water level parameter may be detected by the water level detecting means, and the first water level may be determined according to the first water level parameter. The water level detection device can be a water level sensor, and the control device determines a first water level through a first water level frequency value detected by the water level sensor; the water level detecting means may be a weight sensor, and the control means may determine the first water level from a first water level weight value detected by the weight sensor.

The following steps S202 to S205 are one implementation manner of obtaining the second water level in the tub in the case that the first water level is determined to be higher than the preset water level threshold in the step S102.

Step S202, judging whether the first water level is higher than a preset water level threshold.

Under the condition that the first water level is higher than a preset water level threshold value, indicating that water exists in the barrel body, and entering step S203; and under the condition that the first water level is lower than or equal to the preset water level threshold value, the water is not present in the barrel body, and the step S201 is returned to continue detection.

In step S203, it is determined whether the first water level is lower than the critical water level.

Under the condition that the first water level is lower than the critical water level, the water is indicated to exist in the barrel body, but the water level is lower than the height of the lowest point of the door body (namely the height of the lowest point of the water which can overflow from the door body), the water in the barrel body cannot overflow from the door body at the moment, and step S204 is carried out to further judge whether the water level changes or not; when the first water level is higher than or equal to the critical water level, which indicates that the water in the barrel body exceeds the height of the lowest point of the door body, the water in the barrel body may overflow from the door body at the moment, and the step S207 is performed, and the water draining device is immediately started to drain water.

The critical water level is the lowest water level at which water can overflow from the barrel body, and is determined based on the lowest point of the door body, and the critical water level is stored in the storage space after being determined so as to be convenient for subsequent judgment of the water level.

In step S204, the water level detection device is controlled to detect the water level parameter.

The water level parameter includes at least one of a water level frequency value and a water level weight value.

Step S205, determining a second water level based on the water level parameter.

In the embodiment of the present application, in order to distinguish, the water level parameter detected when the first water level is obtained in step S201 is used as the first water level parameter, and the water level parameter detected when the second water level is obtained in step S204 is used as the second water level parameter.

In order to avoid different measurement accuracy deviation of different detection devices, in the embodiment of the application, a first water level parameter detected when a first water level is acquired and a second water level parameter detected when a second water level is acquired are acquired, wherein the water level detection devices are the same device, namely when the first water level parameter is a first water level frequency value detected by a water level sensor, the second water level parameter is a second water level frequency value detected by the water level sensor; when the first water level parameter is the first water level weight value detected by the weight sensor, the second water level parameter is the second water level weight value detected by the weight sensor.

Step S206, judging whether the laundry treating apparatus is malfunctioning based on the first water level and the second water level.

When it is determined that the laundry treating apparatus is malfunctioning based on the first water level and the second water level, in order to prevent the overflow condition from occurring at this time, step S207 is entered; when it is determined that the laundry treating apparatus has not failed based on the first water level and the second water level, it may be actually failed, but since the time interval is short, the first water level and the second water level are less different, and it is impossible to detect that the failure has occurred, or it may be actually not occurred, so it is necessary to return to step S204 for continuous detection.

In step S207, the drain device of the laundry treating apparatus is controlled to be turned on to drain the water in the tub.

According to the control method provided by the embodiment of the application, under the condition that the first water level is higher than the preset water level threshold, whether the first water level is lower than the critical water level is judged first, so that when the water in the barrel body exceeds the height of the lowest point of the door body, the water draining device is started immediately to drain water, and the water is drained as soon as possible, so that the overflow water quantity is reduced as much as possible. When the water in the barrel body does not exceed the height of the lowest point of the door body, whether the clothes treatment equipment fails or not can be determined as early as possible by determining the change condition of the water level, the water draining device is started immediately when the failure is determined, the water in the barrel body is drained in time, the probability of water leakage failure can be reduced as much as possible, potential safety hazards are eliminated, and the safety of using the clothes treatment equipment is improved.

In some embodiments, the step S206 "determining whether the laundry treating apparatus is malfunctioning based on the first water level and the second water level" in the embodiment shown in fig. 2 may be implemented by:

in step S2061, a water level change value is determined from the first water level and the second water level.

In the embodiment of the application, the water level change value can be determined according to the acquired first water level and second water level, and the difference value between the second water level and the first water level is determined as the water level change value. When the water level rises, the second water level is larger than the first water level, and the water level change value is a positive value; when the water level is reduced, the second water level is smaller than the first water level, and the water level change value is a negative value.

In step S2062, it is determined whether the water level change value is greater than a first preset threshold.

The first preset threshold is a preset value capable of representing the rise of the water level. The first preset threshold is a preset positive number. Comparing the water level change value with a first preset threshold, and when the water level change value is greater than the first preset threshold, indicating that the water level in the barrel body rises, entering step S2063; when the water level variation value is not greater than the first preset threshold value, indicating that the water level in the tub has not risen, it may be determined that the water inlet failure has not occurred in the laundry treating apparatus at this time, and step S2066 is continuously performed to determine whether the water level has fallen to determine whether the water discharge failure has occurred.

In the embodiment of the present application, the first preset threshold may take a value of 5mm (millimeters), and when the difference between the second water level and the first water level is greater than 5mm, step S2063 is entered.

In step S2063, a duration in which the water level variation value is greater than the first preset threshold is acquired.

Step S2064, determining whether the duration reaches a preset duration threshold.

When the duration time is greater than or equal to the preset duration time threshold, that is, the water level change value in the barrel body is always greater than the first preset threshold during the duration time, measurement errors can be eliminated, at this time, it can be determined that the water level in the barrel body is indeed rising, and step S2065 is entered; when the duration is less than the preset duration threshold, it cannot be determined whether the water level in the tub actually rises, and the step S204 is returned to continue the detection until the water level change value is greater than the first preset threshold and the duration reaches the preset duration threshold.

In the embodiment of the application, the preset duration threshold value can take any value between 1s (second) and 5s, for example, the value is 2s.

In step S2065, it is determined that the laundry treating apparatus has a water intake failure.

In some embodiments, when it is determined that the laundry treating apparatus has a water inlet failure, in order to avoid overflow caused by an increase in the water level in the tub, the steps of: detecting the state of a door body, wherein the state of the door body comprises an opening state and a closing state; when the state of the door body is determined to be an open state, the alarm device is controlled to output alarm information, the alarm information is used for prompting a user that the clothes treatment equipment has water inlet faults and the door body is in the open state, the risk of overflow exists, and the user can be prompted to close the door body as soon as possible through the alarm information, so that the overflow water quantity is reduced as much as possible. After determining that the water inlet failure of the laundry treating apparatus occurs, the step S207 is continuously performed to drain water.

In step S2066, it is determined whether the water level change value is smaller than the second preset threshold.

The second preset threshold is a preset value capable of representing the water level drop. The second preset threshold is a preset negative number. Comparing the water level change value with a second preset threshold, and when the water level change value is smaller than the second preset threshold, indicating that the water level in the barrel body is reduced, entering step S2067; when the water level change value is greater than or equal to the second preset threshold value, the water level in the tub body is not raised or lowered, and it can be determined that the laundry treatment apparatus has neither water inlet failure nor water outlet failure, and the process returns to step S204 to continue detection.

In the embodiment of the present application, the second preset threshold may take a value of-5 mm, and when the difference between the second water level and the first water level is less than-5 mm, step S2067 is entered.

In step S2067, it is determined that the laundry treating apparatus has failed in drainage.

After determining that the water discharge failure occurs in the laundry treating apparatus, the step S207 is continuously performed, and the water discharge device is controlled to be opened to discharge water in the tub, so that water discharge is not required when the user maintains the water discharge device, and maintenance time is shortened.

According to the control method provided by the embodiment of the application, whether the water level changes is judged through the first water level and the second water level, and when the water level changes, the failure of the clothes treatment equipment is determined, and water drainage is started; further, whether water inlet faults or water outlet faults occur is determined according to the water level change value, so that maintenance personnel can maintain the water inlet faults or the water outlet faults conveniently, the probability of water leakage faults is reduced as much as possible, potential safety hazards are eliminated, and the safety of using clothes treatment equipment is improved.

In other embodiments, after the control device receives the water level parameter detected by the water level detection device, the control device may directly determine the change value of the water level parameter according to the first water level parameter and the second water level parameter detected by the water level detection device without acquiring the corresponding water level based on the water level parameter, and determine whether the water level in the tub is actually rising based on the change value of the water level parameter, where step S206 "determine whether the laundry treatment apparatus is faulty based on the first water level and the second water level" in the embodiment shown in fig. 2 may be implemented by:

Step S2061', determining a variation value of the water level parameter according to the first water level parameter and the second water level parameter.

In this implementation, the water level parameter includes at least one of a water level frequency value and a water level weight value.

When the water level detection device is a water level sensor, the first water level parameter is a first water level frequency value, and the second water level parameter is a second water level frequency value. Here, the water level sensor may be an air pressure sensor. The higher the water level in the barrel body, the higher the pressure of water to the water level sensor, the larger the inductance of an inductance coil in the water level sensor, the smaller the parallel resonance frequency (namely the water level frequency value) of the inductance and the capacitance, and the smaller the water level frequency value received by the control device. The determining the change value of the water level parameter according to the first water level parameter and the second water level parameter, that is, the determining the change value of the water level frequency according to the first water level frequency value and the second water level frequency value, may be implemented as: and determining the difference value of the first water level frequency value and the second water level frequency value as a change value of the water level frequency. When the water level rises, the water level frequency value is reduced, the first water level frequency value is larger than the second water level frequency value, and the change value of the water level parameter is a positive number. When the water level is lowered, the water level frequency value is increased, the first water level frequency value is smaller than the second water level frequency value, and the change value of the water level parameter is a negative number.

When the water level detection device is a weight sensor, the first water level parameter is a first water level weight value, and the second water level parameter is a second water level weight value. The higher the water level in the barrel body, the greater the gravity of the water to the weight sensor, the greater the inductance of the inductance coil in the weight sensor, and the greater the water level weight value received by the control device. The determining of the change value of the water level parameter according to the first water level parameter and the second water level parameter, i.e. the determining of the change value of the water level weight according to the first water level weight value and the second water level weight value, may be implemented as: and determining the difference value between the second water level weight value and the first water level weight value as a change value of the water level weight. When the water level rises, the water level weight value is increased, the first water level weight value is smaller than the second water level weight value, and the change value of the water level parameter is a positive number. When the water level is lowered, the water level weight value is reduced, the first water level weight value is larger than the second water level weight value, and the change value of the water level parameter is a negative number.

Step S2062', determine whether the variation value of the water level parameter is greater than a third preset threshold.

The third preset threshold is a preset value capable of representing the change of the water level parameter. The third preset threshold is a preset positive number.

Based on the foregoing embodiments, an embodiment of the present application further provides a control method applied to a laundry treatment apparatus, and fig. 3 is a schematic flow chart of still another implementation of the control method provided by the embodiment of the present application, as shown in fig. 3, where the control method includes the following steps:

in step S301, it is determined that the laundry treating apparatus is in a non-operating state, the water level detecting device is controlled to detect a first water level parameter, and the first water level is determined based on the first water level parameter.

The first water level parameter includes at least one of a first water level frequency value and a first water level weight value.

In step S302, it is determined whether the first water level is higher than a preset water level threshold.

Under the condition that the first water level is higher than the preset water level threshold, indicating that water exists in the barrel body, and at the moment, entering step S303; and under the condition that the first water level is lower than or equal to the preset water level threshold value, the water is not present in the barrel body, and the step S301 is returned to continue detection.

In step S303, it is determined whether the first water level is lower than the critical water level.

The critical water level is the lowest water level at which water can overflow from the tub. Under the condition that the first water level is lower than the critical water level, the water in the barrel body is indicated to exist, but the water level is lower than the height of the lowest point of the door body, the water in the barrel body cannot overflow from the door body at the moment, and step S304 is carried out to further judge whether the water level changes or not; when the first water level is higher than or equal to the critical water level, which indicates that the water in the tank body exceeds the height of the lowest point of the door body, the water in the tank body may overflow from the door body at this moment, and the process proceeds to step S312 to drain.

Step S304, the water level detection device is controlled to detect a second water level parameter, and the second water level is determined based on the second water level parameter.

The second water level parameter includes at least one of a second water level frequency value and a second water level weight value.

Step S305, determining a water level variation value according to the first water level and the second water level.

Step S306, judging whether the water level change value is larger than a first preset threshold value.

The first preset threshold is a preset value capable of representing the rise of the water level. The first preset threshold is a preset positive number. Comparing the water level change value with a first preset threshold, and when the water level change value is larger than the first preset threshold, indicating that the water level in the barrel body rises, entering step S307; when the water level change value is not greater than the first preset threshold, it is indicated that the water level in the tub is not rising, and it may be determined that the water inlet failure does not occur in the laundry treating apparatus at this time, step S310 is continuously performed, and it is determined whether the water level is lowered to determine whether the water discharge failure occurs.

Step S307, a duration time when the water level variation value is greater than the first preset threshold value is acquired.

Step S308, judging whether the duration reaches a preset duration threshold.

When the duration time is greater than or equal to the preset duration time threshold, that is, the water level change value in the barrel body is always greater than the first preset threshold during the duration time, measurement errors can be eliminated, at this time, it can be determined that the water level in the barrel body has indeed risen, and step S309 is entered; and when the duration is smaller than the preset duration threshold, whether the water level in the barrel body is actually raised cannot be determined, and returning to the step S304 to continue detection until the water level change value is larger than the first preset threshold and the duration reaches the preset duration threshold.

Step S309, determining that the laundry treating apparatus has a water inlet failure.

After the laundry treating apparatus has a water inlet failure, step S312 is performed to drain water.

Step S310, judging whether the water level change value is smaller than a second preset threshold.

The second preset threshold is a preset value capable of representing the water level drop. The second preset threshold is a preset negative number. Comparing the water level change value with a second preset threshold, and when the water level change value is smaller than the second preset threshold, indicating that the water level in the barrel body is reduced, entering step S311; when the water level change value is greater than or equal to the second preset threshold value, the water level in the barrel body does not rise or fall, at this time, it can be determined that the laundry treatment device has no water inlet failure or no water outlet failure, and the step S304 is returned to continue detection.

Step S311, determining that the laundry treating apparatus has a drain failure.

In step S312, the drain device of the laundry treating apparatus is controlled to be opened to drain the water in the tub.

Step S313, generating corresponding fault information according to the fault of the laundry treating apparatus.

When the fault of the clothes treatment equipment is a water inlet fault, generating fault information corresponding to the water inlet fault, such as generating a water inlet fault code E1; when the failure of the laundry treating apparatus is a drain failure, failure information corresponding to the drain failure is generated, such as a drain failure code "E2" is generated.

Step S314, the control alarm device outputs alarm information corresponding to the fault information.

In the embodiment of the application, when the clothes treatment equipment breaks down, the alarm device is controlled to output alarm information corresponding to the fault information, so that a user can know the faults of the clothes treatment equipment in time and know what kind of faults occur according to different alarm information corresponding to different faults, and the clothes treatment equipment can be maintained in time based on the faults, thereby reducing the occurrence probability of water leakage faults as much as possible, eliminating potential safety hazards and improving the safety of using the clothes treatment equipment.

In the embodiment of the application, the alarm information can comprise at least one of alarm sound, alarm prompt information and alarm fault codes. Controlling the alarm device of the laundry treating apparatus to output alarm information may include: the sounding module of the control alarm device sounds an alarm; and/or a first display module of the control alarm device displays alarm prompt information; and/or a second display module controlling the alarm device displays an alarm fault code. Here, the sounding module may be a sound output module such as a loudspeaker, the alarm sound may be intermittent buzzing sound, and the intermittent duration of the alarm sound corresponding to different faults may be different; the first display module can be an indicator light such as a light emitting diode (LED, light Emitting Diode) light, the alarm prompt information can flash for the LED light, and the flash frequency of the alarm prompt information corresponding to different faults can be different; the second display module may be an output module capable of displaying a code or a number, such as a digital tube, and the alarm fault code may be a fault code, such as preset fault codes "E1" and "E2" corresponding to a fault, and a user may determine that the fault occurring in the laundry treatment apparatus according to the fault code is: water inlet failure and water discharge failure.

Step S315, a prompt message is sent to a terminal having a connection relationship with the laundry processing apparatus.

The prompt message at least carries fault information, so that a user can check the terminal to know what kind of fault occurs in the clothes treatment equipment.

In some embodiments, when the laundry treatment apparatus is capable of being connected to the terminal and transmitting information, the laundry treatment apparatus is controlled to generate a prompt message to the terminal, for example, a transmission module of the alarm device is controlled to transmit an alarm fault code to the terminal.

In practical application, the prompt message may also carry correction information for how to remove the fault, where the correction information may be stored in a storage space of the laundry treatment device, and the corresponding correction information is obtained from the storage space according to the fault information, and the fault information and the corresponding correction information are carried in the prompt message and sent to the terminal. Or when the correction information corresponding to the fault information is not stored in the storage space of the clothes treatment device, the clothes treatment device or the terminal can acquire the correction information from the server according to the fault information, so that a user can timely learn that the clothes treatment device is faulty, and timely maintain the clothes treatment device based on the fault.

According to the control method provided by the embodiment of the application, the probability of occurrence of the water leakage fault is reduced, the potential safety hazard is eliminated, the safety of using the clothes treatment equipment is improved, the alarm device is controlled to output alarm information corresponding to the fault information, and a prompt message is further sent to the terminal, so that a user can timely acquire that the clothes treatment equipment is in fault and acquire what kind of fault occurs according to different alarm information corresponding to different faults, the maintenance is timely performed based on the occurring fault, the probability of occurrence of the water leakage fault is further reduced, the maintenance is timely performed when the water inlet fault occurs, and the water is saved.

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

In the drum washing machine, the water inlet valve is damaged occasionally in the market, so that water is not only fed, but also overflows from the drum if the door is not locked, and the user is lost. The washing machine can detect whether the water level exceeds the gate seal or not, and the water is automatically drained after exceeding the gate seal, but the water level detection is influenced by the deviation of the water level sensor, the crystal oscillator frequency deviation of the chip and different environment temperatures, and the actual water level is possibly higher than the detected water level, so that the water cannot be drained in time when water is leaked.

In order to solve the problem of water leakage of the washing machine caused by the occurrence of precision deviation of the water level sensor, the embodiment of the application provides a drum washing machine with a water level monitoring function, and fig. 4 is a schematic flow chart of still another implementation of the control method provided by the embodiment of the application, as shown in fig. 4, the method comprises the following steps:

step S401, detecting a first water level.

In the shutdown state or the standby state, the control device controls the water level sensor to detect a first water level frequency value in the barrel body, and the first water level is determined according to the first water level frequency value.

Step S402, judging whether the first water level is higher than the heating protection water level.

When it is detected that the first water level exceeds the heating protection water level, proceeding to step S402; when it is detected that the first water level does not exceed the heating protection water level, the process returns to step S401 to continue the detection.

Here, the heating protection water level L0 may be an extremely low water level, such as a water level that can be considered to just exceed the heating pipe.

Step S403, determining whether the first water level is higher than the door seal water level.

The gate seal water level is especially the water level L1 at the lowest point of the gate body. When the first water level is higher than the heating protection water level L0, continuing to judge whether the first water level is higher than the gate seal water level L1, and when the first water level is higher than the gate seal water level L1, entering step S408; when the first water level is not higher than the gate seal water level L1, the process proceeds to step S404.

Step S404, detecting the second water level.

Step S405, it is determined whether the water level rises based on the first water level and the second water level.

When it is determined that the water level in the tub rises based on the first water level and the second water level, it proceeds to step S406; when it is determined that the water level in the tub does not rise based on the first water level and the second water level, the process returns to step S404.

Step S406, judging whether the water level frequency difference value is larger than a preset threshold value.

When the water level frequency difference value is larger than the preset threshold value, determining that water inlet faults occur, and entering step S407; when it is determined that the water level in the tub rises based on the first water level and the second water level, but the water level frequency difference is less than or equal to the preset threshold, it is not yet determined whether a water inlet failure occurs, and at this time, the step S404 is returned to continue the detection.

Here, the water level frequency difference is a difference between a first water level frequency value corresponding to the first water level and a second water level frequency value corresponding to the second water level. The preset threshold may take a value of 150Hz.

Step S407, judging whether the duration time when the water level frequency difference value is larger than the preset threshold value reaches the preset duration time threshold value.

When the duration time that the water level frequency difference value is larger than the preset threshold value reaches the preset duration time threshold value, determining that water drainage is needed, and entering step S408; when the duration of the water level frequency difference value greater than the preset threshold value does not reach the preset duration threshold value, step S407 is continuously executed until the duration reaches the preset duration threshold value.

Here, the preset time period threshold may take a value of 2s.

In step S408, the drain pump is started to drain water.

In the embodiment of the application, in the shutdown state or the standby state, the program continuously monitors the water level, when the water level exceeds the extremely low water level L0, if the water level continuously rises, when the change value of the water level frequency value exceeds the set threshold F (e.g. 150 Hz) and the duration exceeds the set time t0 (e.g. 2 seconds), abnormal water inflow is judged, and the drainage pump is started for draining.

According to the method provided by the embodiment of the application, by monitoring the real-time water level and the water level change in real time, when the distance from the door seal position is larger, whether abnormal water inflow exists can be judged in advance, and water overflow is prevented. When abnormal water inflow is monitored, the door is automatically locked, and the prompt message is pushed to the mobile phone of the user through the function of the Internet of things, so that the user can maintain in time.
