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.
The application mainly aims at the technical problems that a large amount of water resources and electric power resources are consumed and the total actual washing time of a user is prolonged in the prior art, and provides a dehydration balance control method.
According to the dehydration balance control method, the clothes treatment device is controlled to dehydrate, when the dehydration imbalance is determined, the load indication information of the clothes treatment device is obtained, if the load indication information indicates a small load state, the dehydration curve is updated, dehydration is performed according to the updated dehydration curve, and if the load indication information indicates a large load state, water injection washing is performed to perform dehydration after balance adjustment. From this, to different loads, adopt different processing methods to dewater, can reduce and hit the bucket number of times, and improve power consumptive, water consumption, the condition consuming time, improve user's use and experience.
A balance control method of dehydration, an apparatus, a laundry treating apparatus, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a dehydration equilibrium control method according to an embodiment of the present application.
As shown in fig. 1, the equilibrium control method of dehydration may include the steps of:
the dehydration balance control method of the embodiment of the present application can be applied to a laundry processing apparatus, which can be a drum washing machine, a pulsator washing machine, a washing and drying all-in-one machine, or can be other types of laundry processing apparatuses, and is not limited thereto.
At present, the execution process of the washing program is as follows: the method comprises the steps of starting, feeding water, washing, draining, dewatering, rinsing 1, draining, dewatering, rinsing 2, draining, dewatering and finishing. The above-mentioned washing process of the washing program is only exemplified as two times, and in practical application, the number of times of rinsing is not limited in the present application, for example, the number of times of rinsing may also be 1 time, 3 times, and the like.
Therefore, in the embodiment of the present application, the laundry treatment device may be controlled to be dehydrated after the washing stage is finished, the laundry treatment device may be controlled to be dehydrated after the rinsing process of the rinsing stage is finished, and the laundry treatment device may be controlled to be dehydrated in the final dehydration stage after the rinsing stage.
In the embodiment of the present application, when the laundry treating device dehydrates, the laundry treating device may be controlled to dehydrate according to an initial dehydration curve, or the laundry treating device may be controlled to dehydrate according to a corresponding dehydration curve when the laundry treating device dehydrates for the previous time, which is not limited in the present application.
The dehydration curve may indicate a corresponding dehydration beat, for example, the dehydration curve may indicate a rotation-stop period of the motor, such as indicating a rotation time period corresponding to the rotation period of the motor, a stop time period corresponding to the stop period of the motor, a ratio of the rotation time period and the stop time period of the motor (or referred to as a rotation-stop ratio of the motor), and indicate a change of speed and/or acceleration of the motor with time in each period, such as indicating a change of speed and/or acceleration of the motor with time in the rotation period.
And 102, if the dehydration imbalance is determined, acquiring load indication information of the clothes treatment device.
In the embodiment of the application, whether the clothes treatment device is unbalanced in dehydration can be detected through the related sensor, namely whether the washing tub of the clothes treatment device collides with the washing tub is determined. As an example, referring to fig. 2, a clothes treating apparatus is exemplified as a pulsator washing machine. Wherein, clothing processing apparatus is at the operation in-process, if the clothing after the drainage is inhomogeneous in the washtub distribution, then at the dehydration in-process, washtub (or inner tube) can produce the rocking of certain degree, when the eccentric degree of washtub is higher, the continuous rocking of washtub can trigger and hit a bucket sensor (or hit a bucket switch), and then according to hitting the data of bucket sensor output, can confirm that the dehydration is uneven.
In the embodiment of the present application, when the dehydration imbalance is determined, the load indication information of the laundry treating apparatus may be acquired.
As one possible implementation manner of the embodiment of the present application, the laundry treating apparatus may include a weighing unit, and the load indication information may be determined according to data output by the weighing unit. Specifically, the weighing unit may weigh the laundry in the washing tub when the laundry treating apparatus is started for washing, and when the data output from the weighing unit is greater than or equal to a preset threshold, it may be determined that the load indicating information indicates a large load state, and when the data output from the weighing unit is less than the preset threshold, it is determined that the load indicating information indicates a small load state. The preset threshold may be preset for a built-in program of the laundry treatment apparatus, or may be set by a user to improve flexibility and applicability of the method, which is not limited thereto.
It should be understood that the larger the load of the laundry in the washing tub, the more the amount of water to be injected for washing or rinsing, and the smaller the load of the laundry, the less the amount of water to be injected for washing or rinsing, in order to enhance the washing effect of the laundry, so that, as another possible implementation manner of the present application, when it is determined that there is a dehydration imbalance, the load indication information may be determined according to the water filling level of the laundry treatment apparatus, which is referred to as a target water filling level in the present application. Specifically, when the target fill water level is greater than or equal to the threshold water level, it may be determined that the load indication information indicates a large load state, and when the target fill water level is less than the threshold water level, it may be determined that the load indication information indicates a small load state. The threshold water level may be preset by a built-in program of the laundry treatment apparatus, or the threshold water level may be set by a user, which is not limited thereto. For example, the threshold water level may be an L-range water level.
And 103, if the load indication information indicates a small load state, updating the dehydration curve, and dehydrating according to the updated dehydration curve.
In the embodiment of the application, the balance state of the clothes treatment device for dehydration or the influence on the difference of hitting the bucket can be determined in advance by experimental simulation under different direction unbalance loading conditions and different loading conditions when dehydration is performed at different dehydration beats, the best preset number of dehydration curves in the balance state are determined according to the experimental result, or the preset number of dehydration curves with the lowest probability of hitting the bucket are determined, and the dehydration curves are stored. That is to say, the dehydration is carried out by utilizing different dehydration beats under different azimuth unbalance loading conditions and different loading conditions through experiments, the bucket collision conditions under different dehydration beats are analyzed, and the dehydration curves with the preset number, which have the lowest bucket collision probability, are selected from the dehydration curves. Wherein, the corresponding dehydration beats of different dehydration curves are different.
In this embodiment, when the load indication information indicates a low load state, at this time, the current dehydration curve may be updated according to the stored dehydration curves, for example, a dehydration curve may be randomly selected from the stored dehydration curves, or the dehydration curves may be sequentially selected from the stored dehydration curves, the current dehydration curve may be updated according to the selected dehydration curve, and dehydration may be performed according to the updated dehydration curve.
For example, the dehydration process mainly includes: intermittent dewatering, continuous dewatering, inertia dewatering and braking, however, in the intermittent dewatering stage, the rotating speed of the washing barrel is increased from low speed to high speed under the driving of the motor, at the moment, the condition of unbalanced dewatering is easy to occur, when the dewatering is unbalanced and the clothes processing device is in a small load state, at the moment, the acceleration and/or the speed of the motor can be reduced, so that the eccentricity degree of the washing barrel is improved, and the probability of barrel collision is reduced. And, need not to carry out water injection washing and dewater after balancing adjustment, can the using water wisely to and shorten dehydration duration, improve user's use experience.
And 104, if the load indication information indicates a large load state, performing water injection washing to perform dehydration after balance adjustment.
The applicant analyzes the root cause of tub collision caused by eccentricity of the washing tub, determines that the dewatering beat has an important influence on the tub collision, changes the dewatering curve to effectively improve the tub collision problem when the tub collision occurs due to unbalance loading under the condition of small load, and changes the dewatering curve to have an unobvious effect on improving the condition of tub collision caused by eccentricity of the washing tub under the condition of large load. Therefore, in the present application, in order to improve the tub collision problem, when the load indication information indicates a large load state, the water injection washing may be directly performed to perform the dehydration after the balance adjustment. Therefore, different processing modes are adopted for dehydration aiming at different loads, the barrel collision times can be reduced, the power consumption, the water consumption and the time consumption are improved, and the use experience of a user is improved.
According to the dehydration balance control method, the clothes treatment device is controlled to dehydrate, when the dehydration imbalance is determined, the load indication information of the clothes treatment device is obtained, if the load indication information indicates a small load state, the dehydration curve is updated, dehydration is performed according to the updated dehydration curve, and if the load indication information indicates a large load state, water injection washing is performed to perform dehydration after balance adjustment. From this, to different loads, adopt different processing methods to dewater, can reduce and hit the bucket number of times, and improve power consumptive, water consumption, the condition consuming time, improve user's use and experience.
In the embodiment of the application, after dewatering according to the updated dewatering curve, whether the updated dewatering curve is used for dewatering is required to be detected, when the dewatering balance is determined, the updated dewatering curve can be used for continuing dewatering until the dewatering is finished, when the dewatering imbalance is determined, the dewatering curve can be updated again, the dewatering curve which is updated again is used for dewatering, and whether the dewatering balance is detected. That is, in the present application, when the dehydration is unbalanced, the dehydration curve update and the dehydration may be performed a plurality of times until the dehydration balance is determined. Therefore, the dewatering curve can be continuously updated when the dewatering is unbalanced, so that the load eccentricity condition of the washing barrel is optimized, and the barrel collision probability is reduced. The above process is described in detail with reference to example two.
Fig. 3 is a schematic flow chart of a dehydration equilibrium control method according to a second embodiment of the present application.
As shown in fig. 3, the equilibrium control method of dehydration may include the steps of:
The execution process of step 201 may refer to the execution process of step 101 in the above embodiment, and is not described again.
In step 202, the dewatering imbalance is determined, and the load indication information of the clothes treatment device is obtained.
It should be noted that the execution process of the dehydration process mainly includes: the method comprises the steps of intermittent dehydration, continuous dehydration, inertial dehydration and braking, wherein a collision barrel is mainly generated in an intermittent dehydration stage because in the intermittent dehydration stage, a washing barrel is driven by a motor, the rotating speed of the washing barrel is increased from a low speed to a high speed, and at the moment, the condition of unbalanced dehydration is easy to generate, so that a collision barrel sensor can be adopted to detect whether the dehydration is unbalanced or not in the process that the motor of the clothes treatment device drives the washing barrel to operate intermittently, when the dehydration is determined to be unbalanced, the target water injection level of the clothes treatment device can be obtained as load indication information, and if the target water injection level is greater than or equal to a threshold water level, the load indication information is determined to indicate a large load state; and if the target water filling level is less than the threshold water level, determining that the load indication information indicates a small load state.
In step 203, if the load indication information indicates a low load state, the dewatering curve is updated for each time according to each set candidate curve.
In the embodiment of the application, the influence on the difference of collision of the buckets when dehydration is carried out at different dehydration beats can be determined by experimental simulation in advance under different azimuth unbalance loading conditions and different loading conditions, and the preset number of dehydration curves with the lowest probability of collision of the buckets can be determined according to the experimental result, so that the selected preset number of dehydration curves can be used as the set candidate curves.
In the embodiment of the present application, when it is determined that the dewatering is unbalanced and the load indication information indicates a small load state, each time of dewatering curve updating may be performed correspondingly, for example, each candidate curve may be sequentially or sequentially read, and according to the candidate curve read each time, the corresponding dewatering curve updating may be performed.
And step 204, every time the dehydration curve is updated, detecting whether the dehydration by adopting the updated dehydration curve is balanced.
In the embodiment of the present application, the dewatering curve is updated once each time, whether the dewatering curve updated this time is balanced or not may be detected, for example, whether the dewatering curve updated this time is balanced or not may be detected by using a bucket collision sensor, when the dewatering balance is determined, the dewatering curve updated this time may be used to continue dewatering until the dewatering is completed, and when the dewatering is determined to be unbalanced, step 205 may be executed.
And step 205, if the dehydration imbalance is determined, continuing to update the next dehydration curve.
In the embodiment of the application, when the unbalanced dehydration is determined, the next dehydration curve updating can be continued to improve the eccentricity degree of the washing barrel, so that the probability of barrel collision is reduced.
And step 206, if the load indication information indicates a large load state, performing water injection washing to perform dehydration after balance adjustment.
The process of executing step 206 may refer to the process of executing step 206 in the above embodiments, which is not described herein again.
As a possible implementation manner, because there is a difference in functions between the rinsing stage and the final dewatering stage, in the present application, corresponding balance control can be performed in a targeted manner for the tub collision situation of the dewatering processes of the rinsing stage and the final dewatering stage. Specifically, referring to fig. 4, after step 205 or step 103, the equilibrium control method for dehydration may further include the steps of:
In the embodiment of the application, in the rinsing stage, if all the candidate curves are adopted, the situation of unbalanced dehydration still occurs after the dehydration curves are updated, at this time, in order to shorten the total actual washing time of the user, the dehydration in the rinsing stage can be finished, that is, the intermittent dehydration and the continuous dehydration processes in the rinsing stage are directly skipped, and the inertial dehydration process in the rinsing stage is directly entered.
In the dehydration step after the washing step, if all the candidate curves are used and the dehydration curve is updated, the dehydration imbalance still occurs, and in this case, the dehydration after the washing step may be ended.
In the embodiment of the application, in the final dehydration stage, if all the candidate curves are adopted, after the dehydration curves are updated, the situation of unbalanced dehydration still occurs, at this time, if the dehydration in the dehydration stage is finished, more water is remained in clothes, and the use experience of a user is seriously reduced. Therefore, residual moisture in the clothes can be effectively removed, the probability of barrel collision can be reduced, and the use experience of a user is improved.
Further, when water injection washing is performed, after the balance adjustment is performed, and then the dehydration in the dehydration stage is performed again, if the clothes treatment device is determined to maintain the unbalanced dehydration, an alarm prompt can be sent to prompt a user to manually adjust the placing position of the clothes. When the alarm is released, the dehydration process can be executed again.
As a possible implementation manner, because there is a difference in functions between the rinsing stage and the final dewatering stage, in the present application, corresponding balance control can be performed in a targeted manner for the tub collision situation of the dewatering processes of the rinsing stage and the final dewatering stage. In particular, with reference to fig. 5, step 104 or 206 may specifically comprise the following sub-steps:
In the embodiment of the application, when the load indication information indicates a large load state, in the rinsing stage, when the tub collision condition occurs for the first time, namely, when the dehydration is unbalanced, water injection washing can be performed to perform dehydration after balance adjustment, so that the load eccentricity condition is optimized. If the laundry processing device still has the situation of tub collision after the balance adjustment, at this time, in order to shorten the actual washing total time of the user, the motor of the laundry processing device can be directly controlled to stop running, so that the washing tub stops running, namely, the intermittent dehydration and continuous dehydration processes in the rinsing stage are skipped, and the inertial dehydration process in the rinsing stage is directly entered.
In step 402, the load indication information indicates a heavy load state, and water injection washing is performed for a set number of times in the dehydration stage.
In the embodiment of the present application, the set number may be preset by a built-in program of the laundry treatment device, or the set number may be set by a user, which is not limited to this, for example, the set number may be 2, 3, and the like.
And 403, after each water injection washing, draining and dewatering are executed, and whether the dewatering is balanced or not is detected.
In the embodiment of the application, when the load indication information indicates a large load state, in the dewatering stage, when water injection washing is performed for the first time, water drainage and dewatering can be performed after the water injection washing is finished, in the dewatering process, whether the dewatering is balanced can be detected again, if the dewatering is balanced, the dewatering can be continued to the end, and if the dewatering is unbalanced, the water injection washing can be continued to perform the water injection washing so as to perform the dewatering after the balance adjustment until the water injection frequency reaches the set frequency.
Further, after step 403, if the laundry processing apparatus determines that the dewatering imbalance is maintained in each dewatering, an alarm is issued to prompt the user to manually adjust the placement position of the laundry. When the alarm is released, the dehydration process can be executed again.
As an application scenario, in the intermittent dehydration process, dehydration can be performed under different azimuth unbalance loading conditions and different loading conditions through experiments by using different dehydration beats, bucket collision conditions under different dehydration beats are analyzed, and M dehydration curves with the lowest bucket collision probability are selected from the M dehydration curves as set candidate curves.
After the program is started, firstly fuzzy weighing is carried out, different pulse numbers are fed back to the control unit according to the load size, and then the control unit sets different water injection levels according to the different pulse numbers. The large load balancing control process is entered when the control unit determines that the target water filling level of the laundry treating apparatus reaches a threshold level, such as an L-range level, and the small load balancing control process is entered when the control unit determines that the target water filling level of the laundry treating apparatus does not reach the threshold level.
