Description

TECHNICAL FIELD

The present application relates to the field of laundry washing, and more particularly to a washing control method and device for a washing apparatus, an apparatus, and a storage medium.

BACKGROUND

In the related art, the drum washing machine uses the lifting ribs provided on the inner tub to lift up the laundry from the bottom of the tub through the rotation of the inner tub. Under the action of gravity, the laundry falls from a high location to achieve beating washing, so as to clean the laundry. In this washing mode of beating washing, the rotation velocity of the inner tub is generally about 50 rpm. With the advancement of the washing machine control technology, some washing machine products have begun to increase the rotation velocity. Through the high-speed rotation of the inner tub, the laundry is clung to the wall of the inner tub and rotates with the rotation of the inner tub, thereby driving the laundry to be squeezed and flushed in the inner tub, to achieve high-speed rotary tub washing and improve the washing cleaning effect of the washing machine. In this washing mode of the high-speed rotary tub washing, the rotation velocity of the inner tub can reach 200 rpm or even higher. In high-speed rotary tub washing, if the center of gravity of the laundry is unstable, the phenomenon of large vibration or even displacement of the washing machine is prone to occur, which, on the one hand, affects the effect of the washing machine, and on the other hand, may also cause the falling off of the pipe, leak water, and even personal injury.

DETAILED DESCRIPTION

Hereinafter, the present application will be further described in detail in combination with the accompanying drawings and embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to limit the present application.
The embodiments of the present application provide a washing control method for a washing apparatus. The washing apparatus may be a washing machine or a washing and drying machine. For example, the washing apparatus may be a drum type washing machine or a pulsator type washing machine. As shown in FIG.1, the method includes:
In step 101, at least one rotation velocity fluctuation value in a process of increasing a rotation velocity of an inner tub of the washing apparatus to a first set rotation velocity is acquired.
The first set rotation velocity is greater than a critical rotation velocity at which laundry is tightly clung to an inner wall of the inner tub and rotates with a rotation of the inner tub. In the first washing mode, the inner tub of the washing apparatus is controlled to operate at a second set rotation velocity. The second set rotation velocity is greater than the first set rotation velocity, so that the laundry rotates with the rotation of the inner tub, to achieve high-speed washing.
In practical applications, the washing apparatus often works in a second washing mode (also known as a beating washing mode). The second washing mode refers to a mode in which the inner tub of the washing apparatus is controlled to operate at a fourth set rotation velocity, which is less than the critical rotation velocity. At this time, the rotation velocity of the inner tub is generally about 50 rpm. Since the laundry is not tightly clung to the inner wall of the inner tub, it may be necessary to use the lifting ribs provided on the inner tub to lift up the laundry from the bottom of the inner tub. Under the action of gravity, the laundry falls from a high location to achieve beating washing. The washing efficiency is limited by the rotation velocity of the inner tub. In order to improve the washing efficiency, in the related art, the washing apparatus is often controlled to operate alternately in the first washing mode and in the second washing mode. For example, the corresponding operating period for the first washing mode and the second washing mode may be set by programs, so as to achieve the alternate operation of the washing modes.
In the embodiments of the present application, when it is determined that the washing apparatus needs to be switched to the first washing mode, the washing apparatus may acquire at least one rotation velocity fluctuation value in a process of increasing a rotation velocity of an inner tub to a first set rotation velocity. The washing apparatus may determine whether the washing apparatus needs to be switched to the first washing mode according to whether the operating period corresponding to the second washing mode ends. If the operating period for the second washing mode ends, it is determined that the washing apparatus needs to be switched to the first washing mode. At this time, the washing apparatus controls the inner tub to be accelerated, and acquires at least one rotation velocity fluctuation value in a process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity.
Here, the washing apparatus may determine the rotation velocity fluctuation value by collecting a current signal and/or a voltage signal for reflecting the rotation velocity fluctuation of the motor.
In practical applications, the washing apparatus controls the rotation velocity of the inner tub to be increased to the first set rotation velocity, and at least one rotation velocity increasing stage may be set. For example, the rotation velocity of the inner tub is firstly controlled to be increased to a third set rotation velocity, and is maintained at the third set rotation velocity for a certain period of time, and the rotation velocity is then controlled to be increased from the third set rotation velocity to the first set rotation velocity. The third set rotation velocity is less than the first set rotation velocity. The rotation velocity fluctuation value may be the rotation velocity fluctuation value in the rotation velocity increasing process, or the rotation velocity fluctuation value in the rotation velocity maintaining stage.
In step 102, it is determined that the at least one rotation velocity fluctuation value is less than a corresponding rotation velocity fluctuation threshold, and an amount of eccentricity corresponding to the first set rotation velocity is acquired.
In an example, the washing apparatus firstly controls the rotation velocity of the inner tub to be increased to the third set rotation velocity, and to be maintained at the third set rotation velocity for a certain period of time, and then controls the rotation velocity to be increased from the third set rotation velocity to the first set rotation velocity.
Accordingly, the operation that at least one rotation velocity fluctuation value in the process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity is acquired includes:

a first rotation velocity fluctuation value in an acceleration process of increasing the rotation velocity of the inner tub of the washing apparatus to a third set rotation velocity is acquired, wherein the third set rotation velocity is greater than the critical rotation velocity and less than the first set rotation velocity;
a second rotation velocity fluctuation value in a stage of maintaining the rotation velocity of the inner tub of the washing apparatus at the third set rotation velocity is acquired;
a third rotation velocity fluctuation value in an acceleration process of increasing the rotation velocity of the inner tub of the washing apparatus from the third set rotation velocity to the first set rotation velocity is acquired;
a fourth rotation velocity fluctuation value in a stage of maintaining the rotation velocity of the inner tub of the washing apparatus at the first set rotation velocity is acquired.

The operation that it is determined that the at least one rotation velocity fluctuation value is less than the corresponding rotation velocity fluctuation threshold may include:
it is determined that the first rotation velocity fluctuation value is less than the first rotation velocity fluctuation threshold; the second rotation velocity fluctuation value is less than the second rotation velocity fluctuation threshold; the third rotation velocity fluctuation value is less than the third rotation velocity fluctuation threshold; and the fourth rotation velocity fluctuation value is less than the fourth rotation velocity fluctuation threshold.
Here, the first rotation velocity fluctuation threshold, the second rotation velocity fluctuation threshold, the third rotation velocity fluctuation threshold and the fourth rotation velocity fluctuation threshold may be determined based on experiments.
In practical applications, it is possible to select whether the rotation velocity fluctuation value in the increasing process corresponding to each rotation velocity increasing stage and the rotation velocity fluctuation value in the rotation velocity maintaining stage are acquired according to the needs. For example, the operation of acquiring the aforementioned third rotation velocity fluctuation value may be omitted, and the process of judging based on the comparison between the third rotation velocity fluctuation value and the third rotation velocity fluctuation threshold is omitted accordingl y.
In practical applications, the process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity may include one, two or even more rotation velocity increasing stages. The specific number of times of rotation velocity increasing stages may be set according to the capacity and structural strength of the washing apparatus, which is not specifically limited in the embodiments of the present application. It can be appreciated that the more the number of times of rotation velocity increasing stages, the more rotation velocity fluctuation values can be acquire, and the higher the reliability of control is, but the complexity of control also increases.
In some embodiments, it is determined that one of the at least one rotation velocity fluctuation value is greater than or equal to the corresponding rotation velocity fluctuation threshold, the inner tub is controlled to stop rotating, and the operation of acquiring the at least one rotation velocity fluctuation value in the process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity is returned, so as to continue trying to be switched to the first washing mode.
For example, the first rotation velocity fluctuation value in an acceleration process of increasing the rotation velocity of the inner tub of the washing apparatus to a third set rotation velocity is acquired. It is determined that the first rotation velocity fluctuation value is greater than or equal to the first rotation velocity fluctuation threshold. The rotation velocity of the inner tub is then controlled to be returned to zero, and re-controlled to be increased. The first rotation velocity fluctuation value in an acceleration process of increasing the rotation velocity to the third set rotation velocity is acquired, so as to continue trying to be switched to the first washing mode.
In some embodiments, after controlling the inner tub to stop rotating and/or before returning to the operation of acquiring the at least one rotation velocity fluctuation value in the process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity, the method further includes:
the washing apparatus is controlled to disperse the laundry.
Here, the inner tub of the washing apparatus may be controlled to rotate in forward and reverse directions with a set number of rotations, so as to disperse the laundry in the inner tub. Then, the operation of acquiring the at least one rotation velocity fluctuation value in the process of increasing the rotation velocity of the inner tub of the washing apparatus to the first set rotation velocity is returned, so as to continue trying to be switched to the first washing mode. In this way, the success probability of switching the washing apparatus to the first washing mode may be increased.
In some embodiments, the method further includes:

the number of times of controlling the inner tub to stop rotating is counted;
it is determined that the counted number reaches a set value, and the washing apparatus is controlled to skip switching to the first washing mode.

In an example, the number of times of controlling the inner tub to stop rotating may be counted by a counter. If the number of times reaches to the set value n (n is positive integer), the operation of trying to be switched to the first washing mode will be abandoned, that is, the corresponding first washing mode in the program will be skipped, and the subsequent second washing mode will be performed. In practical application, the washing apparatus may also return to step 101 when it is determined that the washing apparatus needs to be switched to the first washing mode in the subsequent operation process.
In this way, the washing apparatus may avoid trying to be switched to the first washing mode in several times, which results in an excessively long operating period.
In step 103, it is determined that the amount of eccentricity is less than a first eccentricity threshold, and the washing apparatus is controlled to be switched to a first washing mode.
Here, it is controlled whether the washing apparatus is switched to the first washing mode based on the comparison result between the amount of eccentricity of the washing apparatus at the first set rotation velocity and the first eccentricity threshold. Here, the first eccentricity threshold may be determined based on experiments.
The embodiments of the present application may avoid the phenomenon of vibration and displacement of the washing apparatus in the first washing mode by judging the at least one rotation velocity fluctuation value in a process of increasing the rotation velocity to the first set rotation velocity as well as the amount of eccentricity corresponding to the first set rotation velocity, before switching the washing apparatus to the first washing mode. Therefore, it is possible to ensure effectively that the washing apparatus is switched to the first washing mode on the premise that the washing apparatus operates reliably and stably, thereby improving the washing efficiency.
In some embodiments, the second set rotation velocity includes at least two rotation velocities greater than the first set rotation velocity. The operation that the washing apparatus is controlled to be switched to the first washing mode includes:

a corresponding rotation velocity of the washing apparatus is determined based on the amount of eccentricity;
the washing apparatus is controlled to operate at the corresponding rotation velocity.

Here, in the first washing mode, levels corresponding to different rotation velocities may be set, and each level has a preset eccentricity threshold interval. The washing apparatus may, determine the eccentricity threshold interval into which the amount of eccentricity is fallen, based on the acquired amount of eccentricity, and determine the operating rotation velocity of the washing apparatus in the first washing mode according to the level corresponding to the eccentricity threshold interval.
Here, in the first washing mode, there may be two or more levels of rotation velocity to finely control the washing apparatus to operate at the corresponding level of rotation velocity, so as to effectively reduce the phenomenon of vibration and displacement in the washing process and improve washing efficiency.
In some embodiments, the method further includes:
it is determined that the washing apparatus operates for a set period in the first washing mode, and the washing apparatus is controlled to be switched to a second washing mode.
In the second washing mode, the inner tub is controlled to operate at a fourth set rotation velocity, which is less than the critical rotation velocity.
In this way, the washing apparatus may operate alternately in the first washing mode and in the second washing mode, until the washing period of the washing apparatus is reached.
In some embodiments, the method further includes:
it is determined that the washing period of the washing apparatus is reached, and the washing apparatus is controlled for rinsing and spinning.
Here, the washing period of the washing apparatus may be set by the user or determined according to the weight of the laundry or adopt a default period. When it is determined that the washing period of the washing apparatus is reached, the washing apparatus is controlled to perform subsequent rinsing and spinning, until the operation of washing apparatus ends.
The present application will be further described in detail in combination with embodiments.
In the embodiments, the washing apparatus is a drum washing machine. The washing apparatus has a low-speed beating washing stage and a high-speed washing stage which operate alternately. The low-speed beating washing stage is the aforementioned second washing mode, and the high-speed washing stage allows the washing apparatus to operate in the aforementioned first washing mode. The first washing mode includes a low level and a high level, in which the rotation velocity corresponding to the low level is lower than the rotation velocity corresponding to the high level.
As shown in FIG.2 and FIG.3, in the embodiments, the control method in the high-speed washing stage includes the following steps.
In step 201, the rotation velocity of the inner tub of the washing apparatus is controlled to be increased to the rotation velocity r1 (i.e. the aforementioned third set rotation velocity), and the rotation velocity fluctuation value w1 in the increasing process is acquired.
Here, when the washing apparatus determines that the operating period in the current second washing mode ends, the rotation velocity of the inner tub of the washing apparatus is controlled to be increased to the rotation velocity r1, and the rotation velocity fluctuation value w1 in the process of increasing the rotation velocity to the rotation velocity r1 is acquired (i.e. the detection of the first rotation velocity fluctuation in FIG.3). The rotation velocity r1 is greater than the critical rotation velocity. For example, the rotation velocity r1 may be 80 rpm (rpm/min).
In step 202, it is judged whether the rotation velocity fluctuation value w1 is less than the rotation velocity fluctuation threshold y1. If the rotation velocity fluctuation value w1 is less than the rotation velocity fluctuation threshold y1, step 203 is performed; if the rotation velocity fluctuation value w1 is not less than the rotation velocity fluctuation threshold y1, step 204 is performed.
If the rotation velocity fluctuation value w1 is less than the rotation velocity fluctuation threshold y1, step 203 is performed; if the rotation velocity fluctuation value w1 is greater than or equal to the rotation velocity fluctuation threshold y1, it is indicated that the washing apparatus does not meet the condition for continuing to increase the rotation velocity, and step 204 is performed.
In step 203, the rotation velocity fluctuation value w2 in a stage of maintaining the rotation velocity of the inner tub at the rotation velocity r1 is acquired.
The washing apparatus acquires the rotation velocity fluctuation value w2 in the process of maintaining the rotation velocity of the inner tub at the rotation velocity r1 for the first set period t1 (i.e. the detection of the second rotation velocity fluctuation in FIG.3). Here, the first set period t1 may be set reasonably according to the rotation velocity r1.
In step 204, the rotation velocity of the inner tub is controlled to be returned to zero, the laundry is dispersed and organized, and step 201 is returned.
The washing apparatus controls the inner tub to stop rotating, and controls the inner tub to rotate in forward and reverse directions with a set number of rotations, so as to disperse the laundry in the inner tub. Then, step 201 is returned to retry to be switched to the first washing mode.
In some embodiments, before returning to step 201, step 204 further includes the operation of counting the corresponding number of times that the rotation velocity is returned to zero and the laundry is dispersed and organized. If the number of times reaches the set maximum threshold n, the corresponding first washing mode in the washing process is skipped, and the subsequent second washing mode is performed.
In step 205, it is judged whether the rotation velocity fluctuation value w2 is less than the second rotation velocity fluctuation threshold y2.If the rotation velocity fluctuation value w2 is less than the second rotation velocity fluctuation threshold y2, step 206 is performed; if the rotation velocity fluctuation value w2 is not less than the second rotation velocity fluctuation threshold y2, step 204 is returned.
In step 206, the rotation velocity of the inner tub is controlled to be increased from the rotation velocity r1 to the rotation velocity r2 (i.e. the aforementioned first set rotation velocity).
Here, the rotation velocity of the inner tub is controlled to continue to be increased to the rotation velocity r2. For example, r2 may be 95 rpm.
In step 207, the rotation velocity fluctuation value w3 in a stage of maintaining the rotation velocity of the inner tub at the rotation velocity r2 is acquired.
The washing apparatus acquires the rotation velocity fluctuation value w3 in the process of maintaining the rotation velocity of the inner tub at the rotation velocity r2 for a second set period t2 (i.e. the detection of the third rotation velocity fluctuation in FIG.3). Here, the second set period t2 may be set reasonably according to the rotation velocity r2.
In step 208, it is judged whether the rotation velocity fluctuation value w3 is less than the third rotation velocity fluctuation threshold y3. If the rotation velocity fluctuation value w3 is less than the third rotation velocity fluctuation threshold y3, step 209 is performed; if the rotation velocity fluctuation value w3 is not less than the third rotation velocity fluctuation threshold y3, step 204 is returned.
In step 209, the amount of eccentricity in the stage of maintaining the rotation velocity of the inner tub at the rotation velocity r2 is acquired.
After maintaining the washing apparatus at the rotation velocity r2 for the second set period t2, it is maintained for a third set period t3 to acquire the amount of eccentricity of the inner tub during the third set period t3 (i.e. the detection of the amount of eccentricity in FIG.3). Here, the third set period t3 may be set reasonably according to the rotation velocity r2.
In Step 210, it is judged whether the amount of eccentricity is less than the first eccentricity threshold. If the amount of eccentricity is less than the first eccentricity threshold, step 211 is performed; if the amount of eccentricity is not less than the first eccentricity threshold, step 204 is returned.
Here, if the amount of eccentricity is greater than or equal to the first eccentricity threshold L1, it is indicated that the amount of eccentricity of the washing apparatus does not meet the condition for switching to the first washing mode, and step 204 is returned. If the amount of eccentricity is less than the first eccentricity threshold LI, it may be necessary to select the low level or the high level in the first washing mode according to the amount of eccentricity, so as to determine the appropriate rotation velocity at which the washing apparatus operates.
In step 211, the rotation velocity of the washing apparatus in the first washing mode is determined based on the amount of eccentricity.
Here, if the amount of eccentricity is greater than or equal to the second eccentricity threshold L2 and less than the first eccentricity threshold L1, the washing apparatus is controlled to operate at the rotation velocity (for example, 150 rpm) with the low level. If the amount of eccentricity is less than the second eccentricity threshold L2, the washing apparatus is controlled to operate at the rotation velocity (for example, 200 rpm) with the high level. Herein, L2 is less than L1.
In practical application, when the operating period of the washing apparatus during high-speed washing reaches to the set period, it is switched to the second washing mode. After the washing apparatus operates in the second washing mode for a corresponding period, the aforementioned control method in the high-speed washing stage is then performed. The cycle is repeated until the washing period of the washing apparatus ends, and then the subsequent rinsing and spinning are performed to complete the washing process.
The washing control method of the embodiments may avoid the phenomenon of vibration and displacement of the washing apparatus in the high-speed washing by judging the at least one rotation velocity fluctuation value in a process of increasing the rotation velocity to the first set rotation velocity as well as the amount of eccentricity corresponding to the first set rotation velocity, before the washing apparatus enters the high-speed washing (i.e. the first washing mode). The appropriate rotation velocity level is selected based on the amount of eccentricity, so that it is possible to reduce effectively the phenomenon of vibration and displacement during washing and improve the washing and cleaning effect.
In order to implement the method of the embodiments of the present application, the embodiments of the present application further provide a washing control device of a washing apparatus. The washing control device of the washing apparatus corresponds to the aforementioned washing control method for the washing apparatus.
