Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.

A laundry treating apparatus, a balance control method, a balance control apparatus, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.

The embodiment of the application provides a balance control method of clothes treatment equipment, which is characterized in that when a barrel collision event occurs in the dehydration process, the severity of the barrel collision is determined according to the displacement of a washing barrel in a plurality of moments within a first preset time before the barrel collision event, and then the balance control is carried out on the washing barrel according to the severity. Because the severity of the barrel collision is determined, the balance control is carried out according to the severity, the precision is high, the washing barrel can be ensured to be adjusted to be in a balanced state, the success rate of dehydration is improved, the dehydration effect is good, and the use experience of a user is improved.

The execution subject of the method is a laundry treatment apparatus, which may be a washing machine, a dry cleaning machine, or the like. The clothes treating apparatus is provided with a displacement detecting apparatus, and the clothes treating apparatus determines the displacement of the washing tub according to the detection data of the displacement detecting apparatus. The displacement detection device may be a gyroscope, an image pickup device, a direction sensor, or the like. The gyroscope or the direction sensor may be installed on an outer sidewall of the tub. The image pickup apparatus may be an infrared camera, and the image pickup apparatus may be installed inside a door cover of the laundry treating apparatus.

When a user washes a load through the laundry treatment apparatus, the user places the load in the washing tub and starts the laundry treatment apparatus to start washing. When the laundry treating apparatus detects that the current washing course is started, detection data of the displacement detecting apparatus at this time is acquired. Judging whether the detection data meets the preset unbalance condition, if so, indicating that the current clothes treatment equipment is in a balanced state, and controlling to execute the current washing program. If the detection data meets the preset unbalance condition, the current clothes treatment equipment is in an unbalance state, and at the moment, if the current washing program is directly executed, a bucket collision event is easy to occur in the washing process, and the noise is high. In this case, therefore, the laundry treating apparatus emits alarm information for prompting that the laundry treating apparatus is in an unbalanced state. After receiving the alarm information, the user can manually adjust the support legs of the clothes treatment device so as to restore the clothes treatment device to the balance state.

After determining that the detection data meets the preset unbalance condition, the clothes treatment device can further determine the inclination direction of the clothes treatment device according to the detection data and send out alarm information comprising the inclination direction, so that a user can know the inclination direction of the clothes treatment device, and further the user can conveniently adjust the support legs of the clothes treatment device in the direction opposite to the inclination direction, and the clothes treatment device is restored to the balance state.

The displacement detection device is exemplified as a gyroscope. The gyroscope can detect the angle of the washing barrel relative to the ground, and detected detection data at least comprise a roll angle and a pitch angle. When the displacement detection device is a gyroscope, a roll angle interval in which a roll angle is defined when the clothes treatment device is in an unbalanced state and a pitch angle interval in which a pitch angle is defined when the clothes treatment device is in an unbalanced state in the unbalanced condition are correspondingly preset, and a preset angle threshold value which is larger than the sum of the roll angle and the pitch angle when the clothes treatment device is in the unbalanced state is also defined.

Wherein the roll angle is used for detecting whether the laundry treating apparatus is balanced in the left-right direction, and the pitch angle is used for detecting whether the laundry treating apparatus is balanced in the front-rear direction. The rolling angle interval can be (-90 degrees, -15 degrees) U.S. 15 degrees, 90 degrees), the pitching angle interval can be (-90 degrees, -15 degrees) U.S. 15 degrees, 90 degrees, and the preset angle threshold can be 10 degrees. The embodiment of the application is not limited to specific values of the roll angle interval, the pitch angle interval and the preset angle threshold, and other values can be set in practical application.

The preset unbalance condition may also define a mapping relationship between an angle interval to which the roll angle belongs and an inclination direction of the laundry treating apparatus in the left-right direction, if the roll angle belongs to (-90 °, -15 ° ], the laundry treating apparatus is inclined to the right, and if the roll angle belongs to [15 °,90 °), the laundry treating apparatus is inclined to the left. The preset unbalance condition can also define the mapping relation between the angle interval of the pitch angle and the inclination direction of the clothes treatment equipment in the front-back direction, if the pitch angle belongs to (-90 degrees, -15 degrees), the clothes treatment equipment is inclined backwards, and if the pitch angle belongs to [15 degrees, 90 degrees), the clothes treatment equipment is inclined forwards. The above-described leftward tilting, rightward tilting, forward tilting, and backward tilting may be tilting directions of the laundry treating apparatus as seen with the user facing the laundry treating apparatus.

The mapping relationship between the angle interval to which the roll angle belongs and the inclination direction, the mapping relationship between the angle interval to which the pitch angle belongs and the inclination direction, and the respective inclination directions are referred to as positional relationships of the user facing the laundry treating apparatus, which are examples, and the embodiment of the present application is not limited thereto.

After the current washing program is started and the roll angle and the pitch angle detected by the gyroscope are obtained, whether the roll angle is in a roll angle interval included by a preset unbalanced condition is determined, and if so, the clothes treatment equipment is determined to be in an unbalanced state. Further, a first inclination direction of the laundry treating apparatus, which is an inclination direction in the left-right direction, is determined according to an angle section to which the current roll angle belongs.

If the roll angle is determined not to be within the roll angle interval, further determining whether the current pitch angle is within a pitch angle interval included in the preset unbalance condition, and if so, determining that the laundry treating apparatus is in an unbalance state. Further, a second inclination direction of the laundry treating apparatus, which is an inclination direction in the front-rear direction, is determined according to an angle section to which the pitch angle belongs.

If the roll angle is determined not to be in the roll angle interval and the pitch angle is determined not to be in the pitch angle interval, calculating the sum of the current roll angle and the pitch angle. Judging whether the sum is larger than a preset angle threshold included in a preset unbalance condition, and if so, determining that the clothes treating equipment is in an unbalance state. Further, an inclination direction of the laundry treating apparatus in the left-right direction is determined according to an angle section to which the roll angle belongs, and an inclination direction in the front-rear direction is determined according to an angle section to which the current pitch angle belongs, and a third inclination direction of the laundry treating apparatus is determined according to the inclination direction in the left-right direction and the inclination direction in the front-rear direction.

For example, assuming that the current roll angle is 7 °, the pitch angle is 5 °, and the preset angle threshold is 10 °, the sum of the roll angle and the pitch angle is 12 ° greater than the preset angle threshold by 10 °. And assuming that the roll angle 7 is located in the angle section 0, 90, the laundry treating apparatus is inclined rightward. The pitch angle of 5 ° is located at an angle interval of 0 °,90 °), the laundry treating apparatus is tilted forward. It may be determined that the laundry treating apparatus is inclined to the right front.

For the case where the laundry treating apparatus is judged to be in an unbalanced state by the sum value between the roll angle and the pitch angle, it is also possible to determine the inclination direction of the laundry treating apparatus and only send out alarm information prompting the unbalance.

After determining the inclination direction of the laundry treatment apparatus in the above manner, the adjustment direction required for adjusting the laundry treatment apparatus to balance may be determined according to the inclination direction, and the adjustment direction may be a direction opposite to the inclination direction of the laundry treatment apparatus, if the inclination direction of the laundry treatment apparatus is inclined to the left, the adjustment direction may be adjusted to the right. After the adjustment direction is determined, if the clothes processing equipment establishes communication connection with the user terminal such as the mobile phone or the computer of the user, the clothes processing equipment also sends suggestion information comprising the adjustment direction to the user terminal. The user terminal receives the suggestion information and displays the suggestion information, and after the user sees the suggestion information, the user can manually adjust the support legs of the clothes treatment equipment according to the adjustment direction suggested by the suggestion information so as to enable the clothes treatment equipment to restore to the balance state.

The clothes treatment equipment sends out alarm information after determining that the clothes treatment equipment is in an unbalanced state in the mode, and the specific clothes treatment equipment can be provided with an indicator lamp for indicating the unbalanced state and can send out alarm information by lighting the indicator lamp. Further, the laundry treating apparatus may be provided with indication lamps corresponding to different inclination directions, and the indication lamps corresponding to the inclination directions may be lighted when the inclination directions of the laundry treating apparatus are determined.

In another implementation, the laundry treatment apparatus may display an alarm message in the display screen, which may be "the laundry treatment apparatus is currently in an unbalanced state, the adjustment foot is set to restore balance". When the inclination direction of the laundry treating apparatus is determined, alarm information including the inclination direction is displayed, and further the suggested adjustment direction may be included in the displayed alarm information. For example, the displayed alarm information may be "the laundry treating apparatus is inclined rightward, please be adjusted leftward to restore the laundry treating apparatus to the balanced state".

In other embodiments, a buzzer may be further provided on the laundry treating apparatus, and an alarm prompt may be issued by the buzzer when it is determined that the laundry treating apparatus is in an unbalanced state. Further, the laundry treatment device may further be provided with a voice playing device, and when it is determined that the laundry treatment device is in an unbalanced state, voice prompt information indicating that the device is unbalanced may be played through the voice playing device. If the inclination direction of the clothes treatment equipment is determined, the played voice prompt information can also comprise the inclination direction or comprise the inclination direction and the corresponding adjustment direction.

When the clothes treatment equipment is detected to be adjusted, the detection data of the adjusted displacement detection equipment are acquired again in the mode, whether the clothes treatment equipment is still in an unbalanced state is determined again according to the detection data, and if the clothes treatment equipment is still in the unbalanced state, alarm information is sent to a user again in the mode so as to prompt the user to continuously adjust the supporting legs of the clothes treatment equipment. And the mode is circularly executed until the clothes treatment equipment is determined to be in the balance state, and the current washing program is controlled to be started.

When the current washing program is started, whether the clothes treating apparatus is in an unbalanced state or not is determined according to the detection data of the displacement detecting apparatus, and an alarm message is sent out when the clothes treating apparatus is determined to be in the unbalanced state, so that a user is prompted that the clothes treating apparatus is in the unbalanced state, and the user is enabled to adjust the supporting legs of the clothes treating apparatus. And furthermore, the suggested adjustment direction can be sent to the user, so that the adjustment efficiency of the user is improved. By the method, the clothes treatment equipment is in a balanced state when the current washing program is executed, the problem that the clothes treatment equipment is unbalanced to cause the bucket collision in the washing process is avoided, the equipment loss caused by the bucket collision is reduced, and the noise in the washing process is reduced.

During the operation of the current washing program, when the washing process is performed to the dehydrating process, as shown in fig. 1, the laundry treating apparatus is balance-controlled by the operations of the following steps 101 to 103, which include:

Step 101: determining a barrel collision event in the dehydration process, and acquiring displacement amounts of the washing barrel at a plurality of moments within a first preset time before the barrel collision event occurs.

The first preset duration may be 8s, 10s, 12s, or the like. The embodiment of the application does not limit the specific value of the first preset duration, and can be set according to the requirement in practical application.

The above-mentioned dehydration process may be a first dehydration process or a second dehydration process in the current washing process, etc. When it is detected that the current washing course is performed to the dehydration course, whether a tub collision event occurs is detected in real time through a tub collision switch provided on the washing tub. When a tub collision event occurs, the tub collision switch is closed under the influence of the collision force of the washing tub, a high level is output, and the controller of the laundry processing apparatus receives the high level output by the tub collision switch, and determines that the tub collision event occurs currently.

After the barrel collision event is determined, detection data of the displacement detection device in a first preset time period before the barrel collision event is obtained. And calculating the displacement of the washing barrel every other preset unit time in the first preset time according to the detection data in the first preset time.

The displacement detection device may be a gyroscope or an image capturing device. When the displacement detection device is a gyroscope, detection data of the gyroscope in a first preset time period before a barrel collision event occurs are obtained, and specifically, detection data of every preset unit time period in the first preset time period can be obtained. And then calculating the displacement of the washing barrel at intervals of a preset unit time according to the acquired detection data. The detection data of the gyroscope at least comprise roll angle and pitch angle. The preset unit time length may be 20ms or 30ms, etc. The embodiment of the application is not limited to a specific value of the preset unit time length, and can be set according to the requirements in practical application.

In other embodiments, the displacement detection device may also be a camera device, such as an infrared camera. The image data shot by the camera equipment in the first preset time before the barrel collision event is generated is acquired, and specifically, the image data shot at intervals of preset unit time in the first preset time can be acquired. And then calculating the displacement of the washing barrel at intervals of a preset unit time according to the acquired image data. Specifically, through an image processing technology, the distance of the washing barrel from the center position in the image is analyzed, and the distance is the displacement of the washing barrel.

The displacement of the washing barrel at intervals of a preset unit time length in a first preset time length before the barrel collision event is generated is obtained in the mode, such as the displacement of the washing barrel at intervals of 20ms in 10s before the barrel collision event is generated. The severity of the current barrel collision event is then determined by the operation of step 102 as follows.

Step 102: and determining the severity degree corresponding to the barrel collision event according to the displacement amount of the washing barrel at a plurality of moments.

As shown in fig. 2, a circle a represents an outer tub of the laundry treating apparatus, a circle b represents an inner tub of the laundry treating apparatus, and a circle b is a washing tub of the laundry treating apparatus according to an embodiment of the present application. When the washing barrel circle b is in a balanced state, the circle center of the washing barrel circle b is o, and when the washing barrel is dehydrated, the washing barrel rotates to shake, so that the washing barrel is outwards centrifugal force, and the washing barrel is displaced. The distance between the center of the circle b when deviating from the center position of the circle b and the center o of the circle in the balance state is the displacement of the washing barrel. The maximum displacement of the washing barrel allowed under the condition of ensuring that the washing barrel cannot collide with the barrel is tested through a large number of tests, namely the distance L between the circle centers o' and o in the figure 2. The maximum displacement amount tested in the clothes treatment equipment is configured as a preset threshold value, and the severity degree corresponding to the barrel collision event is determined according to the preset threshold value when the barrel collision event is determined.

After the displacement of the washing barrel is obtained in the first preset time period before the barrel collision event occurs in the step 101, the abnormal times that the displacement exceeds the preset threshold value are determined according to the obtained displacement of the washing barrel at a plurality of moments.

In one implementation, one displacement amount is randomly selected from the obtained plurality of displacement amounts, and the displacement amount is referred to as a first displacement amount. And judging whether the first displacement exceeds a preset threshold value, and if so, adding one to the abnormal times exceeding the preset threshold value. Since the displacement amount of the washing tub may exceed the preset threshold in a short time when the displacement amount of the washing tub exceeds the preset threshold, if it is continuously judged whether the displacement amount of the interval preset unit time exceeds the preset threshold, it is likely that the judgment is repeated, resulting in a larger number of finally determined abnormalities. Therefore, after the first displacement exceeds the preset threshold, the embodiment of the application acquires the second displacement which is spaced for a second preset time period from the obtained displacement of the washing barrel at a plurality of moments and corresponds to the first displacement, and judges whether the second displacement exceeds the preset threshold.

The second preset time period may be 2s or 2.5s, etc. The embodiment of the application does not limit the specific value of the second preset duration, and can be set according to the requirement in practical application.

Further, in order to avoid repeated judgment of displacement amount with shorter interval events, the embodiment of the application can judge the displacement amount of the washing barrel in a first preset time period before the occurrence of the barrel collision event according to time sequence. Specifically, whether the earliest primary displacement amount in the first preset time period exceeds a preset threshold value is judged, if so, the abnormal times are increased by one, and then whether the displacement amount in the second preset time period after the earliest time period exceeds the preset threshold value is judged. If the earliest primary displacement does not exceed the preset threshold, continuing to judge whether the displacement which is preset for a unit time with the earliest time interval exceeds the preset threshold. And judging sequentially according to the sequence from front to back in time to obtain the abnormal times of the displacement exceeding the preset threshold value. The judgment is carried out according to the time sequence, repeated judgment can be effectively avoided, and the obtained abnormal times are higher in accuracy.

In another implementation manner, it may also be determined whether the displacement amounts of the washing tub at the plurality of moments exceed a preset threshold, that is, whether the displacement amounts of the washing tub at every preset unit time within the first preset time period exceed the preset threshold. Deleting the smallest displacement amount of the two displacement amounts with the time interval smaller than the second preset time length and the displacement amount exceeding the preset threshold, namely comparing whether the time interval of any two displacement amounts is smaller than the second preset time length or not for judging all the displacement amounts exceeding the preset threshold, deleting the smaller displacement amount of the two displacement amounts with the time interval smaller than the second preset time length, and repeatedly comparing until no displacement amount with the time interval smaller than the second preset time length exists in all the rest displacement amounts exceeding the preset threshold finally. And finally, determining the number of the residual displacement exceeding the preset threshold as the abnormal times of the displacement exceeding the preset threshold.

Through the implementation manner, whether the displacement amounts at a plurality of moments exceed the preset threshold can be judged in parallel, the efficiency of determining the abnormal times is higher, and the repeated judgment can be effectively avoided by deleting smaller displacement amounts with the interval time smaller than the second preset duration, so that the obtained accuracy of the abnormal times is higher.

And judging the obtained displacement of the washing barrel at a plurality of moments by any implementation mode, so as to obtain the abnormal times that the displacement of the washing barrel exceeds a preset threshold value in a first preset time before the barrel collision event occurs. And determining the abnormal times as the severity degree corresponding to the barrel collision event. I.e., the greater the number of times the displacement amount of the tub exceeds the preset threshold, the greater the severity of the tub collision.

In other embodiments of the present application, the maximum displacement amount among the displacement amounts of the washing tub every preset unit time period within the first preset time period may be also determined as the severity of the tub collision event.

The severity of the barrel collision determined in this step may include only the number of anomalies when the displacement exceeds a preset threshold, or the severity may include only the maximum displacement within a first preset time period before the barrel collision. Or the severity may include the number of anomalies and the maximum amount of displacement, in which case, the number of anomalies that the amount of displacement exceeds a preset threshold within a first preset time period before the barrel collision occurs may be determined in any of the above ways, and then the maximum amount of displacement is determined from the determined amounts of displacement that exceed the preset threshold, so that the time taken to determine the maximum amount of displacement is shortened, and the efficiency of determining the severity is improved.

According to the displacement of the washing barrel in a first preset time interval in a first preset time before the barrel collision event, the serious degree of the barrel collision is quantized, and the washing barrel is balanced and controlled according to the quantized serious degree, so that the balance control is more accurate, the barrel collision times in the dehydration process are reduced, the dehydration efficiency is improved, and a better dehydration effect is obtained.

Step 103: the tub is balance controlled according to the determined severity.

In the embodiment of the application, after a bucket collision event occurs in the washing bucket, the clothes processing equipment controls and executes a preset balance washing program, water is injected into the washing bucket in the preset balance washing program, and the washing is performed for a certain period of time through a certain washing beat, so that the load in the washing bucket is shaken off, and the load is uniformly distributed in the washing bucket, thereby preventing the washing bucket from being influenced by a large centrifugal force when rotating.

Wherein, the washing beat of the balance washing can be 800RPM, and the washing tub rotates forward for 0.5s, stops for 0.5s, and rotates backward for 0.5s. The default execution time of the balance wash may be 60s. The embodiment of the application does not limit the specific values of the washing beat and the default execution time of the balance washing, and can be set according to the requirements in practical application.

After a barrel collision event occurs in a washing barrel and the severity of the barrel collision is determined, the embodiment of the application adjusts the washing beat and the execution time of a preset balance washing program according to the determined severity, increases the rotation time of the washing barrel in the washing beat by corresponding time, and increases the execution time of the preset balance washing program by corresponding time, thereby achieving the aim of accurately balancing and controlling the washing barrel.

In an application scenario in which the severity includes the number of anomalies whose displacement exceeds a preset threshold, the greater the number of anomalies, the greater the severity of the bucket crash. For different abnormal times, the washing beats and the execution time length of the preset balance washing program are adjusted with different forces. The embodiment of the application divides different times in advance, and configures the increment value of the rotation time length in the washing beats corresponding to the different times in advance and the increment value of the execution time length of the preset balance washing program in the clothes treatment equipment.

When the determined severity degree comprises abnormal times of which the displacement exceeds a preset threshold value, determining a time interval to which the abnormal times belong. And controlling and executing a preset balance washing program according to the frequency interval. Specifically, according to the number of times interval, an added value of the execution duration of the balance washing corresponding to the number of times interval is obtained from the preconfigured information, and the added value is called a first duration. And acquiring an added value of the rotation time length of the washing beats of the balanced washing corresponding to the time interval, and calling the added value as a second time length. The execution time length of the preset balance washing program is increased by a first time length corresponding to the time interval, and the rotation time length included in the washing beat of the preset balance washing program is increased by a second time length corresponding to the time interval.

For example, it is assumed that a mapping relationship between a number of times interval and a first time period for which a balance wash execution time period is increased and a second time period for which a rotation time period is increased is preconfigured as shown in table 1. Assume that the washing cycle of the preset balance washing program is 800RPM, and the tub is rotated forward for 0.5s, stopped for 0.5s, reversed for 0.5s, and the default execution time of the balance washing is 60s. The determined severity includes an abnormal number of 4 times, and the washing takt of the adjusted preset balance washing program becomes 800RPM, and the washing tub is rotated forward for 0.7s, stopped for 0.5s, rotated backward for 0.7s, and the execution time of the balance washing is adjusted to 75s.

TABLE 1

The above-mentioned frequency interval and the corresponding first duration and second duration are only examples, and the embodiment of the present application does not specifically limit the values of these parameters, and may be set according to the needs in practical applications.

According to the method, the rotation time length in the washing beat of the preset balance washing program and the execution time length of the preset balance washing program are adjusted according to the times that the displacement of the washing drum exceeds the preset threshold value in the first preset time length before the collision of the washing drum occurs, the preset balance washing program is accurately adjusted according to the quantized severity degree, and the adjusted preset balance washing program is ensured to enable the washing drum to recover the balance state.

In an application scenario in which the severity includes a maximum displacement amount exceeding a preset threshold, the greater the maximum displacement amount, the higher the severity of the barrel collision. For different maximum displacement, the adjustment forces of the washing beats and the execution time length of the preset balance washing program are different. The embodiment of the application divides different proportion intervals in advance according to the proportion that the maximum displacement exceeding the preset threshold exceeds the preset threshold, and configures the increment value of the rotation time length in the washing beat corresponding to the different proportion intervals and the increment value of the execution time length of the preset balance washing program in the clothes processing equipment in advance.

When the determined severity comprises the maximum displacement exceeding the preset threshold, calculating the proportion of the maximum displacement exceeding the preset threshold, and determining the proportion interval to which the proportion belongs. And controlling to execute a preset balance washing program according to the proportion interval. Specifically, according to the proportion interval, an added value of the execution time length of the balance washing corresponding to the proportion interval is obtained from the preconfigured information, and the added value is called a third time length. And acquiring an added value of the rotation time length of the washing beats of the balanced washing corresponding to the time interval, and calling the added value as a fourth time length. And increasing the execution time of the preset balance washing program by a third time corresponding to the proportion interval. And increasing the rotation time length included in the washing beats of the preset balance washing program by a fourth time length corresponding to the proportion interval.

For example, it is assumed that a mapping relationship between the proportional interval and the third time period for which the balance washing execution time period is increased and the fourth time period for which the rotation time period is increased is preconfigured as shown in table 2. Assume that the washing cycle of the preset balance washing program is 800RPM, and the tub is rotated forward for 0.5s, stopped for 0.5s, reversed for 0.5s, and the default execution time of the balance washing is 60s. The determined severity includes a maximum displacement of 7cm, exceeding a preset threshold of 5cm, and the maximum displacement exceeds the preset threshold by 40%. The ratio interval to which this ratio belongs is [30%, ++ infinity a) of the above-mentioned components, the third time period for which the execution time period of the balance wash is increased is 30s and the fourth time period for which the rotation time period is increased in the washing process is 0.2s. The washing cycle of the preset balance washing program after the adjustment becomes 800RPM, and the washing tub is rotated forward for 0.6s, stopped for 0.5s, rotated backward for 0.6s, and the execution time of the balance washing is adjusted to 90s.

TABLE 2

The preset threshold value, the proportional interval, and the corresponding third duration and fourth duration are only taken as an example, and the embodiment of the application does not specifically limit the values of the parameters, and can be set according to the needs in practical application.

According to the method, the rotation time length in the washing beat of the preset balance washing program and the execution time length of the preset balance washing program are adjusted according to the maximum displacement of the washing barrel within the first preset time length before the barrel collision occurs, the preset balance washing program is accurately adjusted according to the quantized severity degree, and the adjusted preset balance washing program is ensured to enable the washing barrel to recover the balance state.

In other embodiments of the present application, the determined severity may include both an abnormal number and a maximum displacement, where the abnormal number and the maximum displacement exceed a preset threshold, and in the application scenario, the added value of the execution duration of the preset balanced washing program is a sum of the added value of the execution duration determined based on the abnormal number and the added value of the execution duration determined based on the maximum displacement. Similarly, the increase value of the rotation time period in the washing tempo of the preset balance washing program is the sum of the increase value of the rotation time period determined based on the number of abnormalities and the increase value of the rotation time period determined based on the maximum displacement amount.

For example, assume that the washing cycle of the preset balance washing program is 800RPM, and the tub is rotated forward for 0.5s, stopped for 0.5s, reversed for 0.5s, and the default execution time of the balance washing is 60s. The determined severity included a maximum displacement of 6cm and included 1 anomaly. It is derived from table 1 that the execution period of the balance wash increases by 10s based on the number of anomalies 4 and the rotation period increases by 0.2s in the washing tempo. Assuming that the preset threshold is 5cm, the ratio of the maximum displacement amount exceeding the preset threshold is 20%, the ratio interval is [20%, 30%), the execution time period of the balance washing is increased by 20s based on the maximum displacement amount from table 2, and the rotation time period in the washing beat is increased by 0.1s. The execution time period of the balance washing is increased by 30s and the rotation time period in the washing cycle is increased by 0.3s. After the adjustment, the washing beat of the preset balance washing program becomes 800RPM, and the washing tub is rotated forward for 0.65s, stopped for 0.5s, rotated backward for 0.65s, and the execution time of the balance washing is adjusted to 90s.

In the embodiment of the application, in order to avoid too long time of the preset balance washing after adjustment, a preset value can be preset in the clothes treatment equipment, and when the execution time of the preset balance washing program after adjustment is longer than the preset value, the execution time of the preset balance washing program is determined to be adjusted to the preset value. The preset value may be 100s or 110s, etc., and the embodiment of the present application is not limited to a specific value of the preset value, and may be set according to the needs in practical application.

By setting the preset value, after limiting the execution time length of the preset balance washing program based on the severity of the collision barrel, the execution time length of the preset balance washing program is not longer than the preset value, so that the overlong total time length of the current washing program caused by balance control is avoided, users are prevented from waiting for overlong time, and unnecessary electric energy consumption is reduced.

After the execution time of the preset balance washing program and the rotation time in the washing beat are adjusted according to the severity degree corresponding to the current barrel collision event in the mode, the preset balance washing program is executed, so that loads in the washing barrel are uniformly distributed in the washing barrel, the washing barrel is restored to the balance state, and then the subsequent washing process of the current washing program is continuously operated.

In other embodiments, after determining the maximum displacement amount within the first preset time period before the tub collision in step 102, the laundry treating apparatus may further determine a shaking direction according to the maximum displacement amount, where the shaking direction may be opposite to the maximum displacement amount, and if the direction of the maximum displacement amount is to the right, the determined shaking direction may be to the left. The clothes processing device can send prompt information including the shaking direction to the user terminal through communication connection with the user terminal such as a mobile phone and a computer of the user. The user terminal displays the prompt information to prompt the user to manually drag the load in the shaking direction, so that the load is uniformly distributed in the washing barrel through the intervention of the user, and the washing barrel is restored to the balance state.

In other implementations, after the laundry processing apparatus determines the shake-out direction, a prompt message including the shake-out direction may also be displayed through the display panel, so as to prompt the user to shake out the load. Or the clothes treatment equipment can send out alarm sounds through the buzzer to draw the attention of the user, and then prompt information is displayed, so that the user can see the prompt information when hearing the alarm sounds to the vicinity of the clothes treatment equipment, and the user is prevented from missing the prompt information. Or the clothes processing equipment can play the prompt voice including the shaking direction through the voice player so as to prompt the user to shake the load.

The washing process of the laundry treating apparatus generally includes three dehydration processes: a first dewatering process, a second dewatering process and a last dewatering process (i.e. a last dewatering process). The balance control of the tub is performed according to the operations of the above steps 101 to 103 in both the first dehydration process and the second dehydration process. When the current dehydration process is determined to be the last dehydration process, if the barrel collision event occurs in the last dehydration process, alarm information can be directly sent out, and the alarm information is used for prompting that the clothes treatment equipment is in an unbalanced state. If the current washing process includes more than three dehydration processes, the dehydration processes before the last dehydration process perform balance control on the washing tub through the operations of the above steps 101 to 103.

If a barrel collision event occurs in the last falling process, alarm information is directly sent out, so that the situation that the ending time is suddenly prolonged in the last falling process, and the user cannot feel that the sudden washing time is prolonged when washing is about to end is avoided. And the water content of the load in the last stripping process is probably lower, and the alarm information is directly sent out after the barrel collision is detected, so that the condition that the load is soaked again due to the fact that the preset balance washing program is executed again can be avoided.
