Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the dehydration process, the vibration amplitude of the laundry treating device is large due to the uneven placement of the laundry treating device or the uneven distribution position of the laundry. In the prior art, the laundry treating apparatus implements vibration control by establishing a system model, analyzing the position and size of eccentricity according to vibration signals such as measured force, rotational speed, rotational angle, acceleration, displacement, and the like, and the established system model. However, in practical use, it is found that the laundry treating apparatus is a complex system, the accuracy of the established system model is low, and a long time is consumed in the model calculation, so that the effect of controlling the vibration is not ideal, and the vibration of the laundry treating apparatus is still large during the dewatering process.

In order to solve the problem that the balance control effect of the clothes treatment device in the prior art is not ideal, in the balance control method of the clothes treatment device provided in the embodiment of the application, the clothes treatment device is controlled to execute a dehydration process, water is injected into each chamber of the balance device one by one during the dehydration process, a vibration signal for indicating the vibration degree of the clothes treatment device is further acquired, and when the vibration signal indicates that the vibration degree is smaller than a first threshold value or the water injection into each chamber of the balance device is finished, the step of injecting water into each chamber of the balance device one by one is stopped.

A balance control method of a laundry treatment apparatus according to an embodiment of the present application is described below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a balance control method of a laundry treatment apparatus according to an embodiment of the present disclosure.

As an example, the laundry treating apparatus performing the balance control method shown in fig. 1 may be constructed as shown in fig. 2,

fig. 2 is a schematic structural diagram of a laundry treatment apparatus with an active balance control function according to the present application. Wherein, the laundry treating apparatus includes: the device comprises a box body 20, a water containing unit 12, a washing unit 13, a driving motor 14, a first balancing device 15, a second balancing device 16, a first water supply part 17, a second water supply part 18, a first detection unit 21 and a second detection unit 22.

Wherein, the washing unit 13, for receiving the laundry, is supported by a horizontal or inclined rotation shaft to rotate; a driving motor 14 for driving the washing unit 13 to rotate; a water containing unit 12 for receiving the washing unit 13; the first balancing device 15 and the second balancing device 16 are both hollow and are divided into a plurality of chambers, the first balancing device 15 is arranged at the front end of the washing unit 13, and the second balancing device 16 is arranged at the rear end of the washing unit 13; the first water supply part 17 is arranged at the front end of the water containing unit 12, and the second water supply part 18 is arranged at the rear end of the water containing unit 12; the first detecting unit 21 is disposed at the front end of the water containing unit 12, and the second detecting unit 22 is disposed at the rear end of the water containing unit 12, and detects the vibration of the front end and the rear end of the water containing unit 12.

As shown in fig. 1, the balance control method of the laundry treating apparatus includes the steps of:

step 101, controlling the clothes treatment device to perform a dehydration process.

Specifically, the laundry treating apparatus is in a washing or rinsing state before the dehydration process is performed, and therefore, after the washing and rinsing process is finished, the drain pump starts to operate to drain the water containing unit 12, and after the drainage is finished, the driving motor 14 is controlled to rotate the washing unit 13 from a low speed to a high speed, and the dehydration process is started.

To explain, in the initial stage of the dehydration process, the driving motor 14 is at a low rotation speed to drive the washing unit 13 to perform the laundry scattering process, the laundry treatment apparatus scatters the laundry by beating or the like at the low rotation speed, and then the rotation speed of the motor is increased to another low rotation speed, so that the laundry is more uniformly attached to the inner tub wall of the laundry treatment apparatus. If the clothes are unevenly distributed, the clothes are forcibly dried at high speed, so that the vibration amplitude of the clothes treatment device is too large or the clothes treatment device is displaced, and the clothes treatment device and surrounding articles are damaged. The drive motor 14 can be designed, among other things, as a direct drive motor or as a belt drive.

It should be noted that, in the whole process of controlling the laundry treatment apparatus to perform dehydration, the vibration degree of the laundry treatment apparatus, which is determined according to the structural gap between the water containing unit and the box body, is large, and when the water containing unit impacts the box body, the motor should be controlled to reduce the speed immediately to avoid the water containing unit impacting the box body.

And 102, in the dehydration process, injecting water into each chamber of the balancing device one by one.

In the embodiment of the present application, the number of the balancing devices included in the laundry treating apparatus is not limited, and only one balancing device may be included, or two or more balancing devices may be included. Each balancing device is provided with a corresponding vibration signal and comprises n chambers, wherein n is a natural number greater than or equal to 2.

As a possible scenario, in this embodiment n is chosen to be 3, i.e. each balancing device comprises 3 chambers. Specifically, in performing the dehydration process, 3 chambers of the balancing device are filled with water one by one before. Firstly, determining whether the vibration degree of the clothes treatment device is greater than or equal to a second threshold value or not according to a vibration signal obtained before water injection of the balancing device; wherein the second threshold is greater than or equal to the first threshold, and the second threshold is determined according to a motor rotation speed of the laundry treating apparatus.

Furthermore, for at least two balancing devices, the vibration degrees indicated by the corresponding vibration signals are compared, and the water injection sequence of the corresponding at least two balancing devices is determined according to the magnitude relation between the vibration degrees indicated by the corresponding vibration signals. When the number of the balancing devices is at least two, the at least two balancing devices respectively have corresponding second threshold values.

If the vibration degree indicated by the vibration signal corresponding to the first balancing device is larger than the vibration degree indicated by the vibration signal corresponding to the second balancing device, determining that the water injection sequence of the first balancing device is prior to that of the second balancing device, and injecting water quantity corresponding to the rotating speed of the motor into a first cavity of the first balancing device by the first water supply part; if the vibration degree indicated by the vibration signal corresponding to the second balancing device is larger than the vibration degree indicated by the vibration signal corresponding to the first balancing device, the water injection sequence of the second balancing device is determined to be prior to that of the first balancing device, and the second water supply part firstly injects water quantity corresponding to the rotating speed of the motor into the first cavity of the second balancing device.

As an example, the laundry treating apparatus performing the balance control method of the present embodiment is provided with two balancing devices, as shown in fig. 2, including a first balancing device 15 disposed at a front end of the washing unit 13 of the laundry treating apparatus, and a second balancing device 16 disposed at a rear end of the washing unit 13 of the laundry treating apparatus, each balancing device being hollow inside and including n chambers, where n is a natural number greater than or equal to 2. Meanwhile, the clothes processing device comprises a first water supply part 17 and a second water supply part 18 which are used for injecting water into each cavity of the two balancing devices, wherein the first water supply part 17 is arranged at the front end of the water containing unit 12 and is used for injecting water into each cavity of the first balancing device 15; the second water supply part 18 is disposed at the rear end of the water containing unit 12, and is used to supply water to each chamber of the second balancing device 16.

Specifically, the number of the balancing devices of the clothes treating apparatus in the embodiment is at least two, and each balancing device has a corresponding vibration signal. In the course of executing the dehydration, water is filled into each chamber of the balancing device one by one, firstly, at least two balancing devices of the clothes processing device are compared with the vibration degree indicated by the corresponding vibration signal. The first and second detecting

units

21 and 22 of the laundry washing device detect the vibration levels of the front and rear ends of the water containing unit 12, and then compare the vibration levels of the vibration signals corresponding to the two balancing devices. Further, according to the magnitude relation between the vibration degrees indicated by the corresponding vibration signals, the water injection sequence of the at least two corresponding balancing devices is determined. It should be noted that the amount of water injected into the at least two balancing devices is determined according to the rotation speed of the motor of the laundry treating apparatus. The initial rotation speed of the motor in the water injection process can be controlled to be not less than 120r/min at different motor rotation speed stages, so that the water injection process is set to be performed once at 120r/min, once at 170r/min, once at 240r/min, once at 340r/min and once at 500 r/min. It should be noted that the rotation speed phase of the motor for filling water into the clothes treatment device is only an example, and is not limited to these rotation speeds, the selection of the rotation speed of the motor can be adjusted according to the vibration degree of the clothes treatment device, and if the vibration degree is low, the water filling link can be skipped to directly perform the dehydration process.

As a possible scenario, as shown in fig. 2, if the vibration level indicated by the first balancing means 15 corresponding to the vibration signal is greater than the vibration level indicated by the second balancing means 16 corresponding to the vibration signal, the water injection sequence of the first balancing means 15 is determined to precede that of the second balancing means 16, and the first water supply portion 17 first injects a water amount corresponding to the rotation speed of the motor into the first chamber of the first balancing means 15.

As another possible scenario, if the vibration level indicated by the vibration signal of the second balancing apparatus 16 is greater than the vibration level indicated by the vibration signal of the first balancing apparatus 15, it is determined that the water injection sequence of the second balancing apparatus 16 is prior to that of the first balancing apparatus 15, and the second water supply portion 18 first injects water into the first chamber of the second balancing apparatus 16 at a rate corresponding to the rotation speed of the motor, which is different from the rotation speed of the motor, and the injected water amount is also different from each other.

It should be noted that, if it is determined that the vibration degree of the laundry treatment device is smaller than the second threshold value according to the vibration signal acquired before the balancing device is filled with water, the rotation speed of the motor of the laundry treatment device is increased. And continuously acquiring a vibration signal of the balancing device after the rotating speed of the motor is increased, and performing balance control on each chamber of the balancing device when the vibration degree of the clothes processing device is determined to be greater than or equal to a second threshold value according to the acquired vibration signal of the balancing device.

Step 103, acquiring a vibration signal for indicating the vibration degree of the clothes treatment device.

Wherein the vibration signal is obtained by detecting acceleration or displacement through a vibration detection unit of the clothes treatment device and is used for indicating the vibration degree of the clothes treatment device.

In the embodiment of the present application, the vibration detection unit includes a first detection unit 21 and a second detection unit 22, the acceleration or the displacement of the front end and the rear end of the water containing unit 12 is detected by an acceleration sensor or a displacement sensor, the detection unit uploads the detected data to the control board, and the control board performs final calculation to determine the vibration condition of the laundry treatment device and the vibration variation degree of the laundry treatment device before and after water injection in each chamber of the balancing device.

And 104, stopping executing the step of injecting water into the chambers of the balancing device one by one when the vibration degree indicated by the vibration signal is smaller than the first threshold value or the water injection of each chamber is finished.

The first threshold is determined according to the rotating speed of the motor of the clothes treatment device and is a value which is satisfied by the vibration degree indicated by the vibration signal after water is filled in each chamber. And, when there are at least two balancing devices, the at least two balancing devices have corresponding first thresholds, respectively.

As a possible implementation manner, in the process of injecting water into each chamber, a vibration signal is monitored, and whether the vibration degree is smaller than a first threshold corresponding to a balancing device to which the chamber belongs is judged according to the vibration signal. If the water injection amount is smaller than the first threshold value, stopping executing water injection to the balancing device to which the chamber belongs one by one; if the vibration degree is larger than or equal to the first threshold value, whether the vibration degree is enhanced or not compared with that before water injection is further judged according to the vibration signal. When the vibration degree is weakened compared with that before water injection, water injection is continuously carried out on the current cavity; on the contrary, when the vibration degree is enhanced compared with that before water injection, whether other cavities needing water injection exist in the balancing device is further determined, that is, whether the current water injection cavity is the last cavity in the water injection process of the cavities one by one is judged, if the current water injection cavity is the last cavity, water injection of the balancing device to which the cavity belongs is stopped one by one, and if the current cavity is not the last cavity, that is, other cavities needing water injection still exist, water injection of the current cavity is stopped, and water injection is performed on the other cavities needing water injection instead.

It should be noted that, as just one possible implementation manner, one skilled in the art may know that the determining of whether the vibration degree is smaller than the first threshold corresponding to the balancing device to which the chamber belongs, the determining of whether the vibration degree is enhanced compared to before water injection, and the determining of whether the currently water-injected chamber is the execution sequence of the last chamber in the water injection process of each chamber, and is not limited to the aforementioned sequence.

In this embodiment, the number of the balancing devices included in the laundry treating apparatus is not limited, and only one balancing device may be included, or two or more balancing devices may be included. The foregoing water injection process has been described with respect to how water injection is performed in the case of one balancing device, and the water injection process in the case of two or more balancing devices will be described in detail below.

Specifically, the foregoing water injection process may be performed in parallel or sequentially for each balancing device.

The specific manner of sequentially executing the water injection process will be described in detail in the following embodiments, and in this embodiment, a specific example will be briefly described. As a possible scenario, the vibration detection unit detects the vibration level, and if the vibration level of the currently filled chamber in the first balancing device 15 is increased after water filling, the water filling of the current chamber is stopped, and water filling to the next chamber of the first balancing device 15 is selected, and if the vibration level of the laundry treatment apparatus is decreased after water filling to the next chamber, water filling to the chamber is continued. When detecting that the vibration degree indicated by the vibration signal of the clothes treatment device is less than the first threshold value, stopping the step of filling water into each chamber of the first balancing device 15 one by one, and entering a water filling control link of the second balancing device 16. The vibration detection unit detects that the vibration degree of the clothes treatment device changes in the water injection process of the second balancing device 16, if the vibration degree of the current cavity of the second balancing device 16 after water injection is enhanced, water injection to the cavity is stopped, water injection to the next cavity of the second balancing device 16 is selected, if the vibration degree of the next cavity after water injection is continuously enhanced, water injection to the next cavity is stopped, water injection to the subsequent cavity is continuously selected, the water injection process to the cavities one by one is repeatedly executed until all the cavities of the second balancing device 16 are completely injected, or the vibration degree indicated by the vibration signal of the clothes treatment device is smaller than a first threshold value, the water injection step to the cavities of the balancing device is stopped one by one.

Further, after water is injected into each chamber of at least two balancing devices of the clothes treatment device one by one, the vibration signals corresponding to the balancing devices are obtained again, the vibration degree of the vibration signals is judged according to the vibration signals obtained again, and then whether the balancing control process is successful or not is determined according to whether the vibration signals corresponding to the at least two balancing devices are all smaller than the corresponding third threshold value or not.

Specifically, after the at least two balancing devices stop executing water injection of each chamber one by one, when the vibration signals corresponding to the at least two balancing devices are smaller than the corresponding third threshold, the balance control process is successful. After the at least two balancing devices stop executing water injection of each chamber one by one, when the vibration signals corresponding to the at least two balancing devices are larger than the corresponding third threshold value, the current round of balancing control process is not successful, the rotating speed of the motor of the clothes treatment device is maintained, and the current round of balancing control process is executed again.

Wherein the third threshold may be greater than or equal to the first threshold. Because the water injection sequence of each chamber of at least two balancing devices is different, the vibration signal of the balancing device which injects water first can be influenced by the balancing device which injects water later, therefore, the third threshold value corresponding to the balancing device is larger than the first threshold value, so as to avoid the strict requirement that the third threshold value is equal to the first threshold value, the balancing control process of the current stage is continuously carried out, the situation that the balancing control process cannot enter the next round occurs, and the balancing control efficiency of the clothes treatment device is reduced.

It should be noted that the balance control process includes: according to the motor rotating speed of the clothes treatment device, water is injected into each chamber of a balancing device of the clothes treatment device one by one, a vibration signal used for indicating the vibration degree of the clothes treatment device is obtained after water is injected into each chamber, and when the vibration signal indicates that the vibration degree is smaller than a first threshold value or water injection into each chamber is finished, the step of injecting water into each chamber of the current balancing device one by one is stopped.

In addition, the third threshold should also be less than the second threshold. By setting the third threshold to be smaller than the second threshold, the vibration degree after the preset amount of water is injected into each chamber should be smaller than the vibration degree before the preset amount of water is injected, so that after the step of injecting the preset amount of water into each chamber, although a certain time is consumed, the vibration degree is further optimized.

According to the balance control method of the clothes treatment device, the clothes treatment device is controlled to execute the dehydration process, water is injected into each chamber of the balance device one by one in the dehydration process, the vibration signal used for indicating the vibration degree of the clothes treatment device is further acquired, and when the vibration degree indicated by the vibration signal is smaller than the first threshold value or water injection of each chamber is finished, the step of injecting water into each chamber of the balance device one by one is stopped. According to the method, water is injected into each chamber of the balancing device one by one, so that the vibration degree of the clothes treatment device is weakened, the small vibration amplitude of the clothes treatment device in the whole dehydration process is guaranteed, and the technical problem that the clothes treatment device vibrates greatly in the high-speed dehydration process in the prior art is solved.

For clearly explaining the sequence of the water injection process performed by the balancing devices, referring to fig. 3, a detailed description will be given of a control process for performing balanced water injection on the chambers of the two balancing devices one by one in the foregoing embodiment, and specific steps are as follows:

step 201, determining whether the vibration degree of the laundry treating apparatus is greater than or equal to a second threshold.

Specifically, the rotating speed of the driving motor is increased to drive the rotating speed of the washing unit to a set low rotating speed, before water is injected into each chamber of the balancing device one by one, a vibration signal corresponding to each balancing device is obtained, and whether the vibration degree of the clothes treatment device is larger than or equal to a second threshold value or not is judged according to the vibration signal obtained before water is injected into the balancing device.

If the vibration degree of the laundry treating apparatus is greater than or equal to the second threshold, the balancing control of the laundry treating apparatus is performed in step 202. If the vibration degree of the laundry treating apparatus is less than the second threshold, the vibration control of the laundry treating apparatus is not required, the vibration control step may be skipped directly, the rotation speed of the motor of the laundry treating apparatus is continuously increased, and it is continuously determined whether the balance control is required after the rotation speed of the motor is increased, that is, step 201 is repeatedly performed.

In step 202, the vibration signals of the front and rear balancing devices are compared to indicate the vibration degree.

As a possible implementation manner, at the current rotation speed of the motor of the clothes treatment device, the vibration signals of the two balancing devices at the front end and the rear end of the water containing unit are detected, the vibration degrees indicated by the corresponding vibration signals are compared, and the water injection sequence of the two corresponding balancing devices is determined according to the magnitude relation between the vibration degrees indicated by the corresponding vibration signals.

The two balancing devices comprise a first balancing device arranged at the front end of a washing unit of the clothes treatment device and a second balancing device arranged at the rear end of the washing unit of the clothes treatment device. If the vibration degree indicated by the vibration signal corresponding to the first balancing device is greater than the vibration degree indicated by the vibration signal corresponding to the second balancing device, determining that the water injection sequence of the first balancing device is prior to that of the second balancing device; and if the vibration degree indicated by the vibration signal corresponding to the second balancing device is greater than the vibration degree indicated by the vibration signal corresponding to the first balancing device, determining that the water injection sequence of the second balancing device precedes that of the first balancing device.

Otherwise, the rotation speed of the motor of the clothes processing device is maintained, and the balance control process is executed again.

Wherein, the balance control process comprises: according to the motor rotating speed of the clothes treatment device, water is injected into each chamber of a balancing device of the clothes treatment device one by one, a vibration signal used for indicating the vibration degree of the clothes treatment device is obtained after water is injected into each chamber, and when the vibration signal indicates that the vibration degree is smaller than a first threshold value or water injection into each chamber is finished, the step of injecting water into each chamber of the current balancing device one by one is stopped.

It should be noted that, the above-mentioned process of performing balanced water injection control on each chamber of the balancing apparatus may not include all possible situations, and is only one possible implementation scenario, and those skilled in the art may also implement balanced water injection control on each chamber of the balancing apparatus in other manners, which is not limited herein.

The balance control method of the clothes treatment device comprises the steps of controlling the water injection process of each cavity of the balancing device of the clothes treatment device, obtaining vibration signals after water injection of each cavity, stopping executing the step of injecting water into each cavity of the balancing device one by one when the vibration signals indicate that the vibration degree is smaller than a first threshold value or the water injection of each cavity is finished, stopping executing the step of injecting water into each cavity of the balancing device one by one, and determining whether the balance control process is successful or not according to whether the vibration signals corresponding to at least two balancing devices are smaller than a corresponding third threshold value or not after at least two balancing devices stop executing water injection one by one. According to the method, water is injected into each chamber of the balancing device one by one, so that the vibration degree of the clothes treatment device is weakened, the clothes treatment device is guaranteed to keep smaller vibration amplitude in the whole dehydration process, and the technical problem that the clothes treatment device vibrates greatly in the high-speed dehydration process in the prior art is solved.

In order to further understand the dehydration process of the laundry treatment apparatus, the present embodiment provides another balancing control method, fig. 4 is a flowchart illustrating the balancing control method of the laundry treatment apparatus provided in the third embodiment of the present application, and as shown in fig. 4, the balancing control method of the laundry treatment apparatus may include the following steps:

in step 301, dewatering begins.

Specifically, the laundry treating apparatus is in a washing or rinsing state before performing the dehydration process, and thus, after the washing and rinsing process is finished, the drain pump starts to operate to drain the water containing unit, and after the drainage is finished, the driving motor is controlled to drive the washing unit to rotate from a low speed to a high speed to start the dehydration process.

Step 302, collecting vibration signals.

Specifically, the vibration signal is obtained by detecting acceleration or displacement by a vibration detection unit of the laundry treatment apparatus, and indicates a degree of vibration of the laundry treatment apparatus. The vibration detection is to detect the acceleration or the displacement of the front end and the rear end of a water containing unit of the clothes treatment device through an acceleration sensor or a displacement sensor, the detection unit uploads the detected data to a control board, and the control board carries out final calculation to determine the vibration condition of the clothes treatment device.

Step 303, the low-speed clothes are shaken up and distributed.

Specifically, when the driving motor is in a low-rotation-speed stage, the washing unit is driven to rotate, and the clothes are shaken out and redistributed by the clothes treatment device through actions such as beating and the like under the condition of low rotation speed, so that the existence of large eccentric mass is avoided. If the clothes are not uniformly distributed, the high-speed spin drying is forced, which can cause the vibration amplitude of the clothes treatment device to be too large or to be displaced, and damage is brought to the clothes treatment device and surrounding articles. The driving motor can be designed into a direct-drive motor or a belt transmission driving mode.

Further, when the rotation speed of the driving motor is increased to a certain low rotation speed level and the laundry in the washing unit is more uniformly attached to the inner tub wall, step 304 is performed.

And step 304, judging and controlling the vibration at low rotating speed.

If the vibration level of the laundry treating apparatus is greater than or equal to the second threshold, the balancing control of the laundry treating apparatus is continuously performed in step 305. If the vibration degree of the laundry treating apparatus is less than the second threshold, the vibration control of the laundry treating apparatus is not required, the vibration control step may be skipped directly, the rotation speed of the motor of the laundry treating apparatus is continuously increased, and it is continuously determined whether the balance control is required after the rotation speed of the motor is increased, that is, the step 304 is repeatedly performed.

And step 305, comparing the vibration signals of the front balancing device and the rear balancing device.

The two balancing devices comprise a first balancing device arranged at the front end of a washing unit of the clothes treatment device and a second balancing device arranged at the rear end of the washing unit of the clothes treatment device. If the vibration degree indicated by the vibration signal corresponding to the first balancing device is greater than the vibration degree indicated by the vibration signal corresponding to the second balancing device, determining that the water injection sequence of the first balancing device is prior to that of the second balancing device; and if the vibration degree indicated by the vibration signal corresponding to the second balancing device is greater than the vibration degree indicated by the vibration signal corresponding to the first balancing device, determining that the water injection sequence of the second balancing device precedes that of the first balancing device. After the water injection sequence of the two balancing devices is determined according to the vibration level, step 306 is performed.

And step 306, sequentially injecting water into each chamber of the balancing device in the first order one by one.

In this embodiment of the present application, it is first determined whether the vibration degree corresponding to the balancing apparatus in the previous order is smaller than the corresponding third threshold, and if the current vibration degree of the balancing apparatus is smaller than the corresponding third threshold, the balancing control link of the balancing apparatus is skipped, and step 307 is executed, that is, the balancing control is performed on the balancing apparatus in the next order. And if the current vibration degree of the balancing device is larger than the corresponding third threshold value, carrying out balance control on each chamber of the balancing device.

Specifically, a preset amount of water is injected into a first chamber of a balancing device in a previous sequence, a vibration detection unit detects the change of the vibration degree of the clothes treatment device before and after water is injected into the first chamber, if the vibration degree is increased after water is injected into the first chamber, water injection into the first chamber is stopped, and water injection into a second chamber is selected. Further, the vibration detection unit detects the change of the vibration degree of the clothes treatment device before and after water is filled into the second chamber, if the vibration degree is reduced after water is filled into the second chamber, water is continuously filled into the chamber until the vibration degree indicated by the vibration signal of the clothes treatment device is detected to be smaller than the first threshold value or the vibration level is increased, water is stopped being filled into the second chamber, further, water is stopped being filled into each chamber of the balancing device in the prior sequence one by one, and then the step 307 is continuously executed.

It should be noted that when the vibration degree is increased after the water injection into the second chamber and the water injection into the second chamber is stopped, the water injection into the third chamber is continuously selected, and if the vibration degree is decreased after the water injection into the third chamber, the water injection into the third chamber is continuously performed, and the stop condition of the water injection is the same as the stop condition of the water injection into the second chamber. And if the vibration degree indicated by the vibration signal of the clothes treatment device is still greater than the first threshold when the third chamber stops injecting water, continuing to inject water into the next chamber, and keeping the subsequent water injection process of each chamber the same until all the chambers stop injecting water or the vibration degree in the middle water injection process is less than the first threshold. The balancing control process for the balancing apparatus is then terminated, and the process proceeds to step 307.

And 307, injecting water into each chamber of the balancing device in the last sequence one by one.

In this embodiment of the present application, it is first determined whether the vibration degree corresponding to the balancing device in the subsequent sequence is smaller than the corresponding third threshold, and if the current vibration degree of the balancing device is smaller than the corresponding third threshold, the balancing control link of the balancing device is skipped, and step 308 is executed. And if the current vibration degree of the balancing device is larger than the corresponding third threshold value, carrying out balance control on each chamber of the balancing device.

Specifically, a preset water amount is injected into a first chamber of a balancing device which is arranged in sequence, the vibration detection unit detects the vibration degree change of the clothes treatment device before and after water injection into the first chamber, if the vibration degree is increased after water injection into the first chamber, water injection into the first chamber is stopped, and water injection into a second chamber is selected. Further, the vibration detection unit detects the change of the vibration degree of the clothes treatment device before and after water is filled into the second chamber, if the vibration degree is reduced after water is filled into the second chamber, water is continuously filled into the second chamber until the vibration degree indicated by the vibration signal of the clothes treatment device is detected to be smaller than the first threshold value or the vibration level is increased, water filling into the second chamber is stopped, further, water filling into each chamber of the sequential rear balancing device is stopped one by one, and then step 308 is continuously executed.

It should be noted that when the vibration degree is increased after the water injection into the second chamber and the water injection into the second chamber is stopped, the water injection into the third chamber is continuously selected, and if the vibration degree is decreased after the water injection into the third chamber, the water injection into the third chamber is continuously performed, and the stop condition of the water injection is the same as the stop condition of the water injection into the second chamber. And if the vibration degree indicated by the vibration signal of the clothes treatment device is still greater than the first threshold when the third chamber stops injecting water, continuing to inject water into the next chamber, and keeping the subsequent water injection process of each chamber the same until all the chambers stop injecting water or the vibration degree in the middle water injection process is less than the first threshold. The balancing control process for the balancing apparatus is then terminated, and the process proceeds to step 308.

And 308, comparing and judging whether the balance control of the current round is successful.

Specifically, after water injection of each chamber of the two balancing devices is stopped, whether the vibration signals corresponding to the two balancing devices are smaller than the corresponding third threshold value or not is judged, and then whether the balance control process of the current round is successful or not is determined. Wherein the third threshold is greater than the first threshold.

As a possible implementation manner, if the vibration signals corresponding to the two balancing devices are judged to be smaller than the corresponding third threshold, it is indicated that the balancing control process of the current round is successful, and further, the rotation speed of the motor of the clothes processing device is increased, and the next balancing control process is started.

As another possible implementation manner, if the vibration signals corresponding to the two balancing devices are judged to be greater than the corresponding third threshold, it indicates that the motor rotation speed of the laundry processing device is maintained if the current balancing control process is unsuccessful, and the current balancing control process is executed again, i.e., the process returns to step 304 to execute the balancing control process again.

Wherein, the balance control process includes: according to the motor rotating speed of the clothes treatment device, water is injected into each chamber of a balancing device of the clothes treatment device one by one, a vibration signal used for indicating the vibration degree of the clothes treatment device is obtained after water is injected into each chamber, and when the vibration signal indicates that the vibration degree is smaller than a first threshold value or water injection into each chamber is finished, the step of injecting water into each chamber of the current balancing device one by one is stopped.

And 309, changing the rotating speed for multiple times and controlling according to the vibration degree as required.

Specifically, the rotation speed of the driving motor is increased, vibration signals before water is filled into each chamber of the balancing device of the clothes treatment device again are continuously detected, and whether the vibration degree of the clothes treatment device at the moment is larger than or equal to a second threshold value or not is judged. If the vibration degree is larger than the second threshold value, the rotating speed is kept to enter a balance control link, namely, step 305, step 306, step 307 and step 308 are executed. Until the rotation speed of the motor is increased to the preset maximum rotation speed and the vibration degree of the laundry treating apparatus is less than the second threshold value, step 310 is performed.

At step 310, dewatering is complete.

Specifically, when the rotation speed of the motor is detected to be increased to a preset maximum rotation speed, and the vibration degree of the laundry treating apparatus is less than the second threshold value at this time, the dehydrating process is completed at the rotation speed.

The balance control method of the clothes processing device of the embodiment of the application executes the dehydration process by controlling the clothes processing device; in the dehydration process, before water is injected into each chamber of the balancing device one by one, the front and the rear parts of a water containing unit of the clothes treatment device are detected by vibration level, and the water injection sequence of the balancing device is determined; the effect of balance control is judged by controlling water injection of each chamber of the balance device once, and finally, the dehydration procedure is completed by changing the rotating speed and controlling according to the vibration level as required. According to the method, water is sequentially injected into each chamber of the balancing device, the vibration degree of the clothes treatment device in each stage of the dehydration process is controlled, the small vibration amplitude of the clothes treatment device in the whole dehydration process is guaranteed, and the technical problem that the clothes treatment device in the prior art vibrates greatly in high-speed dehydration is solved.
