Wherein the first threshold value and the second threshold value are determined according to a motor rotation speed of the laundry treating apparatus. When the number of the balancing devices is plural, the plurality of balancing devices have corresponding first and second threshold values, respectively.
Fig. 1 is a flowchart illustrating a balanced water injection control method of a laundry treatment apparatus according to an embodiment of the present application.

The clothes treatment device comprises a balancing device, the balancing device comprises a plurality of chambers, for example, the number of the chambers of the marking balancing device is n, and n is a positive integer greater than or equal to 2. Alternatively, in order to achieve a reduction in the vibration level of the laundry treating apparatus during the dehydration process, the number of the balancing means may be at least one.
As an example, when the number of the balancing devices is 2, referring to fig. 2, fig. 2 is a schematic structural diagram of the laundry treating device according to the embodiment of the present application. Wherein, the laundry treating apparatus includes: the water supply device comprises a box body 10, 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, a second detection unit 22, a third detection unit 23, a plurality of water path switches 24 and a water supply pipeline 25.
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 arranged in a hollow manner 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; a first water supply part 17 disposed at the front end of the water containing unit 12 for supplying water to each chamber of the first balancing device 15, and a second water supply part 18 disposed at the rear end of the water containing unit 12 for supplying water to each chamber of the second balancing device 16; the first detection unit 21 is arranged at the front end of the water containing unit 12 and is used for detecting the vibration degree of the front end of the water containing unit 12, and the second detection unit 22 is arranged at the rear end of the water containing unit 12 and is used for detecting the vibration degree of the rear end of the water containing unit 12; the third detection unit 23 is connected with the plurality of waterway switches 24, and the third detection unit 23 is used for detecting the waterway flow; a plurality of water path switches 24 are connected to the first and second water supply parts 17 and 18 through a water supply line 25 for controlling the supply of water to the first and second water supply parts 17 and 18.
For convenience of explanation, the number of the balancing devices in the embodiments of the present application is 2 examples.
As shown in fig. 1, the equilibrium water injection control method of the laundry treating apparatus includes the steps of:
In the embodiment of the present application, before the dehydration process is performed, the laundry treatment apparatus is in the washing state or the rinsing state, and therefore, after the washing process or the rinsing process is completed, the drainage pump starts to operate to drain the water from the water containing unit 12, and after the drainage is completed, the driving motor 14 is controlled to drive the washing unit 13 to rotate from the low speed to the high speed, so as to start the dehydration process.
Further, 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 clothes shaking process, and the clothes is shaken and redistributed by the clothes treatment device through actions such as beating and the like at the low rotation speed, so that the existence of a large eccentric mass is avoided, and then the rotation speed of the driving motor 14 is increased to another low rotation speed, so that the clothes are uniformly attached to the inner barrel wall of the clothes treatment device.
It can be understood that, in the initial stage of the dehydration process, due to the uneven distribution of the laundry, if the rotation speed of the driving motor 14 is too high, the laundry will be forcibly spin-dried at a high speed, causing the vibration amplitude of the laundry treating apparatus to be too large or displaced, possibly causing damage to the laundry treating apparatus and surrounding articles. The drive motor 14 can be designed as a direct drive motor or as a belt drive. And, the rotation speed of the driving motor 14 should not be lower than the preset threshold, for example, the preset threshold may be 100r/min, so that it can be ensured that water injected into each chamber of the balancing device can completely enter the inside of the chamber under the action of centrifugal force during the dehydration process of the laundry treatment device, thereby avoiding water overflow, on one hand, the balancing effect and the response speed of the balancing device can be improved, and on the other hand, the accuracy of the detection result of the third detection unit 23 can be improved.
In the embodiment of the application, the preset water amount is the water amount which enables the vibration degree to reach the ideal effect and is preset by the control panel of the clothes treatment device, and can be determined according to the motor rotating speed of the clothes treatment device, and the preset water amount is different due to different motor rotating speeds.
Specifically, in performing the dehydration process, a preset amount of water may be sequentially injected into each chamber of the balancing device. For example, in the course of performing the dehydration, after the first water supply part 17 sequentially injects a predetermined amount of water into each chamber of the first balancing means 15, then the second water supply part 18 injects preset water quantity into each chamber of the second balancing device 16 in sequence, alternatively, after the second water supply part 18 injects a preset amount of water into each chamber of the second balancing device 16 in sequence, then, the first water supply part 17 injects a preset amount of water into each chamber of the first balancing device 15 in sequence, or, in the course of performing the dehydration, the vibration degree of the front end of the water containing unit 12 can be detected by the first detecting unit 21, a vibration signal is obtained, and the second detection unit 22 detects the vibration degree of the rear end of the water containing unit 12, obtains a vibration signal, the vibration signals corresponding to the first and second balancing means 15, 16 are compared to determine the water injection sequence of the first and second balancing means 15, 16.
Specifically, if the vibration degree indicated by the vibration signal of the first balancing means 15 is greater than the vibration degree indicated by the vibration signal of the second balancing means 16, it is determined that the water injection sequence of the first balancing means 15 precedes the second balancing means 16, and the first water supply part 17 sequentially injects a preset amount of water into each chamber of the first balancing means 15. And if the vibration degree indicated by the vibration signal corresponding to the second balancing means 16 is greater than the vibration degree indicated by the vibration signal corresponding to the first balancing means 15, it is determined that the water injection sequence of the second balancing means 16 is prior to that of the first balancing means 15, and the second water supply part 18 sequentially injects a preset amount of water into each chamber of the second balancing means 16.
It should be noted that the water filling process can be performed at different motor rotation speed stages, and the water filling 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 500r/min in this embodiment, and the motor rotation speed stages for filling water into the laundry treatment apparatus are only an example and are not limited to these rotation speeds. Whether to skip the water filling process for a certain rotation speed stage may be determined according to the vibration degree of the laundry treating apparatus. For example, if the vibration level is low, the water injection step can be skipped to continuously increase the motor speed.
It should be noted that, because the volume of the balancing device is limited, the balancing capability of the laundry treatment device has a certain upper limit, and after each chamber of the balancing device is filled, the active balancing control capability of the laundry treatment device cannot be exerted, and even the vibration degree of the laundry treatment device may be deteriorated.
Specifically, the laundry treating apparatus may include a vibration detecting unit, by which a vibration level of the laundry treating apparatus may be detected to obtain a vibration signal, for example, the vibration detecting unit may be an acceleration sensor, a velocity sensor, a displacement sensor, a force sensor, or the like, to detect the vibration level of the laundry treating apparatus to obtain the vibration signal. Wherein, the vibration signal may be an acceleration signal or a displacement signal for indicating a vibration degree of the laundry treating apparatus.
Therefore, in the present application, the vibration degree of the laundry treating apparatus before and after the preset amount of water is injected into each chamber may be determined by the vibration detecting unit. Specifically, the vibration detection unit comprises a first detection unit 21 and a second detection unit 22, before the preset water amount is injected into each chamber, the first detection unit 21 detects the acceleration or displacement of the front end of the water containing unit 12 to obtain the vibration signal of the front end of the water containing unit 12, the second detection unit 22 detects the acceleration or displacement of the rear end of the water containing unit 12 to obtain the vibration signal of the rear end of the water containing unit 12, the first detection unit 21 and the second detection unit 22 upload the detected vibration signal to the control panel, the control panel carries out final calculation, and the vibration condition of the clothes treatment device can be determined.
Similarly, after the preset amount of water is injected into each chamber, the first and second detecting units 21 and 22 continue to detect the acceleration or displacement of the front and rear ends of the water containing unit 12, and upload the detected vibration signals to the control board, which performs final calculation to determine the vibration condition of the laundry treatment apparatus. By comparing the vibration conditions of the clothes treatment device before and after the preset water amount is injected into each chamber, the vibration degree of the clothes treatment device before and after the preset water amount is injected into each chamber and the vibration change degree of each chamber of the balancing device before and after water injection can be determined.
And step 104, stopping the subsequent water injection process if the vibration degree is not reduced after the preset water amount is injected into each chamber.
In the embodiment of the application, when the vibration degree is not reduced after the preset water amount is injected into each chamber, the balancing device is determined to have the filled chamber, at the moment, in order to avoid the vibration degree deterioration and other conditions of the clothes treatment device, water injection can be stopped for each chamber of the balancing device, and therefore the situation that the vibration degree deterioration of the clothes treatment device is caused due to the fact that water is continuously injected after each chamber is full can be avoided.
The balance water injection control method of the clothes treatment device, disclosed by the embodiment of the application, executes a dehydration process by controlling the clothes treatment device, then injects a preset water amount into each chamber of the balance device in the dehydration process, simultaneously monitors the vibration degree of the clothes treatment device before and after the preset water amount is injected into each chamber, and finally stops a subsequent water injection process if the vibration degree is not reduced after the preset water amount is injected into each chamber. In this application, through pouring into preset water yield to each cavity of balancing unit, can reduce clothing processing apparatus's vibration degree for among the solution prior art clothing processing apparatus when high-speed dehydration, the great technical problem of clothing processing apparatus's vibration degree. And, can realize the full cavity state of every cavity in the balancing unit is discerned, when the vibration degree is not reduced after every cavity pours into the water volume of presetting into, confirm to exist the cavity in full cavity state, at this moment, can stop the subsequent water injection course, namely stop filling water to every cavity of the balancing unit, on one hand, can avoid the situation that the water injection continues after every cavity is full, cause the waterflow to spill over to other cavities and cause the vibration degree of the processing unit of the clothes to worsen, on the other hand, if the water injection continues after every cavity is full, although can reduce the rotational speed of the electrical machinery through other control means, thus reduce the vibration degree of the processing unit of the clothes, but the more steps among the control program, the control time is longer, in this application, when discerning the cavity in full cavity state, stop filling water to every cavity of the balancing unit immediately, the steps between the control programs can be optimized, and the control time length can be shortened.
In the embodiment of the application, if the chamber with the reduced vibration degree after the preset water amount is injected exists, the chamber in the state of not being full of the chamber is indicated, and at the moment, in order to optimize the vibration degree, the subsequent water injection process can be continuously executed.
Wherein, follow-up water injection process includes: and according to the vibration degree of the clothes treatment device after water is filled into each chamber, selecting a target chamber from each chamber of the balancing device, and filling water into the target chamber to reduce the vibration of the clothes treatment device.
Specifically, the vibration condition of the clothes treatment device and the vibration change degree of each chamber of the balancing device before and after water injection can be determined by detecting the vibration signal at the front end of the water containing unit 12 by the first detection unit 21, detecting the vibration signal at the rear end of the water containing unit 12 by the second detection unit 22 and comparing the vibration degrees of the vibration signals corresponding to the first detection unit 21 and the second detection unit 22. After the vibration change degree before and after water injection of each cavity is determined, at most (n-1) cavities beneficial to vibration attenuation can be selected as target cavities from the n cavities according to the vibration change degree before and after water injection of the n cavities of the balancing device. For example, in the case where the balancing device includes 3 chambers, at most 2 of them are selected as target chambers.
It should be noted that after a preset amount of water is injected into n chambers of the balancing device in sequence, according to the vibration change degree before and after water injection into the n chambers of the balancing device, a chamber beneficial to vibration attenuation is selected from the n chambers as a target chamber, and at most (n-1) chambers, at least two chambers are selected as the target chambers. If n chambers of the balancing device are selected as target chambers, not only the water injection efficiency is reduced, but also the effect of reducing the vibration degree is not ideal, so that only (n-1) target chambers can be selected at most. And the vibration reduction degree of at most (n-1) target chambers after water injection is greater than or equal to the vibration reduction degree of unselected chambers after water injection.
In the embodiment of the application, after the target chamber is selected, water can be injected into the target chamber so as to reduce the vibration of the clothes treatment device. For example, after selecting up to (n-1) target chambers, each of the up to (n-1) target chambers may be sequentially filled with water.
It should be noted that, in order to improve the accuracy and the real-time performance of the full cavity state identification, a preset water amount may be injected into each cavity of the balancing device, and/or during the water injection process of the target cavity, the full cavity state of each cavity may be detected in real time according to the third detection unit 23, so as to determine whether each cavity is full. The above-described identification process is described in detail below with reference to fig. 3.
Fig. 3 is a flowchart illustrating a balanced water injection control method of a laundry treatment apparatus according to a second embodiment of the present application.
As shown in fig. 3, the equilibrium water filling control method of the laundry treating apparatus may include the steps of:
In step 202, a preset amount of water is injected into each chamber of the balancing device during the dehydration process.
The execution process of steps 201 to 202 may refer to the execution process of steps 101 to 102 in the above embodiments, which is not described herein again.
It should be noted that, in order to improve the accuracy and real-time performance of the full-chamber state identification, step 206 may be performed simultaneously during the process of injecting the preset amount of water into each chamber of the balancing apparatus. That is, in the stage of the water injection trial, after each chamber is filled with water, it is required to determine whether each chamber is filled with water, that is, when step 202 is executed, the chamber full determination process needs to be executed synchronously.
The process of step 203 may refer to the process of step 103 in the above embodiments, which is not described herein again.
And step 205, selecting a target chamber from each chamber of the balancing device according to the vibration degree of the clothes treatment device after water is filled into each chamber, and filling water into the target chamber to reduce the vibration of the clothes treatment device.
In the embodiment of the present application, in order to improve the accuracy and the real-time performance of the full cavity state identification, step 206 may be synchronously performed during the water injection process of the target cavity. That is, in the stage of equilibrium water filling, water is not continuously filled into the target chambers, but in the process of filling water into each target chamber, whether the vibration degree of the clothes treatment device meets the requirement is determined, that is, whether the vibration degree of the clothes treatment device is smaller than the first threshold value is determined, if yes, water filling is stopped, if no, water filling into the target chambers is continued, and whether each target chamber is filled with water is monitored simultaneously in the process of water filling. That is, the full cavity judgment process needs to be performed simultaneously when step 205 is performed.
In step 206, a full cavity determination process is performed.
Specifically, the third detecting unit 23 may count the amount of water injected into each chamber to determine whether each chamber is full, and when it is detected that there is a full chamber, the water injection into each chamber of the balancing device is stopped, so as to avoid the situation that the vibration degree of the laundry processing device is deteriorated due to the fact that the water flows overflow to other chambers because the water injection continues after each chamber is full.
As a possible implementation manner, the third detecting unit 23 may be a flow meter, and the number of pulses corresponding to each chamber in the water filling time period may be counted by the flow meter to determine whether each chamber is full. In particular, referring to fig. 4, step 206 may specifically include the following sub-steps:
In the embodiment of the present application, when the third detecting unit 23 is a flow meter and the waterway switch 24 is an electromagnetic valve, the connection relationship of the flow meter, the electromagnetic valve, and the balancing device may be as shown in fig. 5. The positions of the flow meters and the electromagnetic valves can be changed, the number of the flow meters is 1, the number of the electromagnetic valves is multiple, and each electromagnetic valve is connected with one chamber of the balancing device.
Specifically, in the water injection process, water is injected into only one chamber during single water injection, the electromagnetic valve can open the valve corresponding to the designated chamber according to a control instruction, and meanwhile, the water flow injected into the designated chamber can be counted through the flowmeter to determine the corresponding pulse number. Therefore, in the process of controlling the electromagnetic valve to carry out water injection on each chamber of the balancing device one by one, the corresponding pulse number of each chamber in the water injection time period can be counted through the flow meter. It should be noted that, in order to improve the accuracy of the full cavity state identification, if water is injected into the same cavity for multiple times, the number of pulses corresponding to the cavity determined by the flow meter in the multiple water injection process needs to be accumulated to obtain an accumulated value, and the accumulated value is used as the number of pulses determined by water injection into the corresponding cavity.
At step 2062, it is determined whether each chamber is full based on the number of pulses.
In the embodiment of the application, the pulse number limit value corresponding to the full cavity state of each cavity can be set in advance according to the capacity of each cavity of the balancing device, and after the pulse number corresponding to each cavity is determined, the obtained pulse number can be compared with the pulse number limit value corresponding to the full cavity state of each cavity to determine whether each cavity is filled.

As a possible implementation manner, referring to fig. 6, after the target chamber is filled with water, the balanced water filling control method of the laundry treating device may further include the steps of:
In the embodiment of the application, the vibration signal of the clothes treatment device can be collected in real time through the vibration detection unit, and when the vibration degree of the clothes treatment device is determined to be smaller than the first threshold value according to the vibration signal, at the moment, because the vibration degree of the clothes treatment device is lower, water injection to the target cavity can be stopped.
And step 302, increasing the rotating speed of the motor.
In the embodiment of the application, when the vibration degree of the clothes treatment device is low, the water injection link can be skipped, the motor rotating speed of the clothes treatment device is increased to high rotating speed for dehydration, and the dehydration efficiency is improved.
And 303, storing the pulse number of each chamber before the rotating speed of the motor is increased so as to be used for accumulating the pulse number of each chamber determined by the flow meter with the stored pulse number of the corresponding chamber after the rotating speed of the motor is increased, and determining whether each chamber of the balancing device is filled according to the accumulated pulse number of each chamber.
In the embodiment of the application, in order to improve the accuracy of full cavity state identification, before the rotating speed of the motor is increased, the pulse number of each cavity of the balancing device needs to be stored, after the rotating speed of the motor is increased, if water is injected into each cavity again, the pulse number of each cavity determined by the flow meter and the stored pulse number of the corresponding cavity can be accumulated, and whether each cavity of the balancing device is full or not is determined according to the accumulated pulse number of each cavity so as to improve the accuracy of full cavity state identification of each cavity.
Further, after stopping filling water into each chamber of the balancing device, it may be detected whether the vibration degree of the laundry treating device is greater than or equal to a second threshold, and if the vibration degree of the laundry treating device is greater than or equal to the second threshold, the water may be drained from each chamber of the balancing device, and the laundry treating device may be controlled to perform the dehydration process again, and during the dehydration process, the water may be filled into each chamber of the balancing device to reduce the vibration of the laundry treating device. It should be noted that, since the time of the dehydration process is limited, the number of times of the repeated execution should not be higher than a threshold number of times, wherein the threshold number of times is preset, for example, preset for a built-in program of the laundry treating apparatus. And when the dewatering process is executed again, water is injected into each chamber of the balancing device so as to reduce the frequency of the step of reducing the vibration of the clothes treatment device to reach the threshold frequency, if the filled chambers are determined to exist again and the vibration degree of the clothes treatment device is greater than or equal to the second threshold value, the dewatering process is ended after the current rotating speed is maintained to operate for the preset time. Wherein the preset duration is preset.

Specifically, if the current water injection balancing device is a balancing device that injects water first, the next action may be a water injection link of the balancing device that injects water later. If the current water injection balancing device is a balancing device for water injection at the back, the next action can be to increase the rotating speed of the motor, namely, the rotating speed of the motor of the clothes treatment device is increased to a higher rotating speed for dehydration, so that the dehydration efficiency is improved.
For example, assuming that the first balancing means 15 is filled with water in a sequence prior to the second balancing means 16, if the balancing means currently filled with water is the first balancing means 15, a water filling process of the second balancing means 16 may be performed, and if the balancing means currently filled with water is the second balancing means 16, the motor rotation speed of the laundry treating apparatus may be increased to a higher rotation speed for dehydration, thereby improving the dehydration efficiency.
It should be noted that, after the filling and draining are monitored, the stored pulse numbers of the chambers need to be deleted, and the pulse numbers of the chambers can be counted again to improve the accuracy of the full-chamber state identification of the chambers when the clothes treatment device is controlled to execute the dehydration process again.
