Referring to fig. 1 and 2, fig. 1 is a flow chart of a balance correction method of the present invention; fig. 2 is a flow chart of a balance correction method according to an embodiment of the present invention. As shown in fig. 1, the balance correction method of the present invention includes the following steps:
s1, acquiring a washing water level gear of a washing machine;

s3, determining a balance correction water level gear of the washing machine according to the washing water level gear and the current balance correction times;
and S4, selectively executing a balance correction program of the washing machine according to the balance correction water level gear and the current balance correction times.
Preferably, in the process of obtaining the current balance correction times of the washing machine and obtaining the washing water level gear of the washing machine, the current balance correction times of the washing machine can be obtained first, and then the washing water level gear of the washing machine can be obtained; or the washing water level gear of the washing machine can be obtained first, and then the current balance correction times of the washing machine can be obtained; the present balance correction times and the washing water level steps of the washing machine can be obtained simultaneously, and those skilled in the art can flexibly adjust and set the current balance correction times and the washing water level step obtaining sequence of the washing machine in practical application, without departing from the principle and scope of the present invention.
In a preferred embodiment, in the step S1, the step of "acquiring a washing water level gear of the washing machine" includes:
s11, obtaining the weight of an object to be cleaned;
and S12, determining a washing water level gear according to the weight of the objects to be washed.
Of course, the determination method of the wash water level step is not limited to the above-mentioned method, and the water level frequency of the wash water may be directly obtained by the water level sensor, and the wash water level step may be determined by the water level frequency, or the wash water level step directly selected by the user.
In a preferred embodiment, before the step S3 "determining the balance correction water level shift of the washing machine according to the washing water level shift and the current balance correction times", the balance correction method further includes:
s13, comparing the washing water level gear with a preset gear threshold;
and S14, determining the total balance correction times of the washing machine according to the comparison result of the washing water level gear and the preset gear threshold.
Preferably, the washing water level gears are divided into a plurality of water level gears, and the balance correction times of the washing machine are reasonably determined according to different water level gears, so that the most reasonable balance correction times can be provided for the washing machine when the washing machine runs washing programs of different washing water level gears, the waste of water resources is avoided, and the use experience of a user is improved. Further, the water level gears are divided into three levels, namely a low water level gear, a medium water level gear and a high water level gear, wherein the division of the water level gears can be flexibly adjusted and set according to actual conditions, for example, experimental water level gears obtained by a person skilled in the art according to experiments under specific working conditions or empirical water level gears obtained according to experiments can be only required to meet the requirement of determining the balance correction times of the washing machine according to the water level gears.
The preset gear threshold comprises a first preset gear threshold and a second preset gear threshold.
Preferably, in the step S14, the step of determining the total balance correction times of the washing machine according to the comparison result between the washing water level gear and the preset gear threshold specifically includes:
s141, if the washing water level gear is less than or equal to a first preset gear threshold, judging that the total balance correction frequency is a first total correction frequency;
s142, if the washing water level gear is larger than the first preset gear threshold but smaller than or equal to the second preset gear threshold, determining that the total balance correction times is a second total correction times;
s143, if the washing water level gear is larger than a second preset gear threshold, judging that the total balance correction times are third total correction times;
the first total correction times are larger than the second total correction times, and the second total correction times are larger than the third total correction times.
Specifically, in step S141, if the wash water level is less than or equal to the first preset level threshold, which indicates that the water level in the washing tub is low, and the consumption of the wash water is small each time the water filling balance operation is performed, the total consumption of the wash water is small for the multiple water filling balance operations, and the total balance correction number of the washing machine is determined as the first total correction number.
Further, in step S142, if the water level is greater than the first preset water level threshold but less than or equal to the second preset water level threshold, which indicates that the water level in the washing tub is moderate, and the consumption of the washing water is moderate each time the water filling balance operation is performed, the total consumption of the washing water for the multiple water filling balance operations is moderate, in order to reduce the total consumption of the washing water, the total balance correction frequency of the washing machine is determined to be the second total correction frequency, which is less than the first total correction frequency, so as to reduce the number of balance corrections of the washing machine, thereby reducing the total consumption of the washing water.
Further, in step S143, if the water level gear is greater than the second preset water level gear threshold, it indicates that the water level gear in the washing tub is high, and the consumption of the washing water is also high when performing the water filling balance operation each time, the total consumption of the washing water for performing the water filling balance operation for multiple times will be very large, and in order to reduce the total consumption of the washing water, the total balance correction number of the washing machine is determined to be a third total correction number, which is smaller than the second total correction number, so as to reduce the number of balance corrections of the washing machine, thereby reducing the total consumption of the washing water, and achieving the purpose of determining the total balance correction number of the washing machine according to the water level gear, so that the washing machine can provide the most reasonable total balance correction number for the washing machine when running the washing programs of different water level gears, thereby avoiding the waste of water resources, and further improving the use experience of the user.
In the above steps, by setting the first preset gear threshold and the second preset gear threshold, a conclusion of determining whether the total balance correction frequency of the washing machine is the first total correction frequency and determining whether the total balance correction frequency of the washing machine is the second total correction frequency can be given, so that the washing machine adopts the optimal balance correction frequency under different conditions, waste of water resources is avoided, and use experience of a user is improved. The setting of the first preset gear threshold and the second preset gear threshold can be flexibly adjusted and set according to actual conditions, for example, the first preset gear threshold is the highest water level of the low water level gear, the second preset gear threshold is the highest water level of the medium water level gear, and the requirement that the total balance correction times of the washing machine are determined by the first preset gear threshold and the second preset gear threshold is met.
In a preferred embodiment, in the step S3, the step of determining the balance correction water level shift of the washing machine according to the washing water level shift and the current balance correction times includes:
s31, determining a basic gear of a balance correction water level gear according to a washing water level gear;
s32, determining gears needing to be added to the basic gears according to the current balance correction times;
s33, determining a balance correction water level gear according to the basic gear and the gear needing to be added to the basic gear;
wherein, the balance correction water level gear is less than or equal to the maximum water level gear of the washing machine.
Specifically, since the washing water level steps are related to the weight of the objects to be washed, in order to uniformly distribute the objects to be washed with the weight in the washing tub, the basic steps of the balance correction water level steps can be determined according to the washing water level steps, that is, the washing water level steps are equal to the basic steps; and because the objects to be cleaned are unevenly distributed in the washing barrel under the action of the washing water at the washing water level gear, in order to ensure that the objects to be cleaned are evenly distributed in the washing barrel, the gear required to be added at the basic gear is determined according to the current balance correction times, and the balance correction water level gear is determined according to the sum of the gear required to be added at the basic gear and the gear required to be added at the basic gear, so that the balance correction water level gear is improved, the balance correction water level gear is larger than the washing water level gear, the objects to be cleaned can be quickly and evenly distributed under the action of the washing water at the higher balance correction water level gear, the balance correction effect of the washing machine is improved, the most reasonable balance correction program is provided for the washing machine, and the use experience of a user is improved.
Preferably, in the case where it is determined that the total balance correction count is the first total correction count, the maximum gear to be added to the base gear is the first maximum gear. For example, the first total correction number is five, the first maximum gear is third gear, and the basic gear is fourth gear; when the water injection balance correction is executed for the first time, the gear needing to be added to the basic gear is the first gear, and the balance correction water level gear is the fifth gear; when the water injection balance correction is executed for the second time, the gear needing to be added to the basic gear is two gears, and the balance correction water level gear is six gears; when water injection balance correction is executed for the third time, the gear needing to be added to the basic gear is the third gear, and the balance correction water level gear is the seventh gear; and when the water injection balance correction is executed for the fourth time and the fifth time, the gear needing to be added to the basic gear is still the third gear, and the balance correction water level gear is the seventh gear.
Preferably, in a case where it is determined that the total balance correction count is a second total correction count, the maximum gear to be added to the base gear is a second maximum gear, and the first maximum gear is larger than the second maximum gear. For example, the second total correction number is four, the second maximum gear is two, and the basic gear is five; when water injection balance correction is executed for the first time, the gear needing to be added to the basic gear is the first gear, and the balance correction water level gear is the sixth gear; when the water injection balance correction is executed for the second time, the gear needing to be added to the basic gear is two gears, and the gear of the balance correction water level is seven gears; and when the water injection balance correction is executed for the third time and the fourth time, the gear needing to be added to the basic gear is still two gears, and the gear of the balance correction water level is seven gears.
Preferably, in a case where it is determined that the total number of balance corrections is the third total number of corrections, the maximum gear to be added to the basic gear is the third maximum gear, and the second maximum gear is larger than the third maximum gear. For example, the third total correction number is three, the third maximum gear is first gear, and the basic gear is sixth gear; when the water injection balance correction is executed for the first time, the gear needing to be added to the basic gear is the first gear, and the balance correction water level gear is the seventh gear; and when the water injection balance correction is executed for the second time and the third time, the gear needing to be added to the basic gear is still the first gear, and the balance correction water level gear is the seventh gear.
It should be further noted that when the basic level is the same as the maximum water level of the washing machine, the water filling balance operation is performed according to the maximum water level of the washing machine, and the balance correction water level is not required to be increased.
Of course, the first total correction frequency, the second total correction frequency, the third total correction frequency, the first maximum gear, the second maximum gear, the third maximum gear, the basic gear, and the gear to be added to the basic gear each time the water injection balance correction is performed are not limited to the above-mentioned gears, and those skilled in the art can flexibly adjust and set the first total correction frequency, the second total correction frequency, the third total correction frequency, the first maximum gear, the second maximum gear, the third maximum gear, the basic gear, and the gear to be added to the basic gear each time the water injection balance correction is performed in practical application.
In a preferred embodiment, the washing machine includes a washing tub, and the step of "selectively executing the balance correction program of the washing machine according to the balance correction water level step and the current balance correction times" in the step S4 includes:
s41, counting the frequency of tub collision of the washing tub under the condition that the washing machine is in a dehydration stage;
s42, judging whether the counted times are greater than or equal to a preset time threshold value or not;
s43, if the counted times are smaller than a preset time threshold, maintaining the current dehydration operation of the washing machine;
and S44, if the counted times are more than or equal to the preset times threshold, selectively executing water filling balance operation of the washing machine according to the balance correction water level gear and the current balance correction times.
Specifically, in step S43, if the counted number of times is less than the preset number of times threshold, it may be determined that the objects to be washed in the washing tub are uniformly distributed but the washing tub accidentally collides with the washing tub, or that the objects to be washed in the washing tub are not uniformly distributed but cross over the resonance region of the washing machine after colliding with the washing tub for several times, and the washing machine does not need to be subjected to a water injection balancing operation, so that the washing machine maintains the current dewatering operation; in step S44, if the counted number of times is greater than or equal to the preset number of times threshold, it may be considered that the objects to be cleaned in the washing tub are not uniformly distributed and cannot cross the resonance region of the washing machine, and a water injection balancing operation needs to be performed on the washing machine, so that the objects to be cleaned in the washing tub are uniformly distributed, the water injection balancing operation of the washing machine is selectively performed according to the balance correction water level and the current balance correction number, thereby achieving the purpose of selectively performing the water injection balancing operation of the washing machine according to the number of times that the washing tub collides with the washing tub, so that the most reasonable balance correction program can be provided for the washing machine when the washing tub collides with the washing tub for different times, thereby improving the effect of balance correction of the washing machine, and further improving the user experience.
In the above process, through setting the preset time threshold, the conclusion that whether the washing machine selectively executes the water injection balance operation of the washing machine can be further given, so that the washing machine can adopt an optimal balance correction program under different conditions, and the objects to be cleaned in the washing tub can be uniformly distributed in the washing tub. The setting of the preset number threshold may be flexibly adjusted and set according to an actual situation, for example, in a case where it is determined that the total balance correction number is the first total correction number, the preset number threshold is the first preset number threshold, and the first preset number threshold is 1; under the condition that the total balance correction times are judged to be second total correction times, the preset time threshold is a second preset time threshold, the first preset time threshold is smaller than the second preset time threshold, and the second preset time threshold is 2 times; in the case where it is determined that the total balance correction times is the third total correction times, the preset time threshold is a third preset time threshold, the second preset time threshold is smaller than the third preset time threshold, and the third preset time threshold is 3 times, that is, the preset time threshold is gradually increased as the washing water level is increased, and the values of the first preset time threshold, the second preset time threshold, and the third preset time threshold are not limited to the above-listed values as long as the requirement for selectively performing the water injection balance operation of the washing machine, which is determined by the first preset time threshold, the second preset time threshold, and the third preset time threshold, is satisfied.
Preferably, the step of "selectively performing the water filling balance operation of the washing machine according to the balance correction water level step and the current balance correction times" in the step S44 includes:
s441, judging whether the current balance correction times are less than or equal to the total balance correction times;
s442, if the current balance correction times are larger than the total balance correction times, the washing machine is enabled to execute rinsing operation;
and S443, if the current balance correction times are smaller than or equal to the total balance correction times, enabling the washing machine to execute water filling balance operation according to the balance correction water level gears.
Specifically, in step S442, if the current balance correction number is greater than the total balance correction number, which indicates that the washing machine has performed the balance correction by the same number as the total balance correction number, the objects to be washed in the washing tub still cannot be uniformly distributed, and the washing machine is caused to perform the rinsing operation in order to avoid the waste of water resources; in step S443, if the current balance correction frequency is less than or equal to the total balance correction frequency, it is determined that the balance correction can be continued to uniformly distribute the objects to be washed in the washing tub, and the washing machine is operated to perform a water filling balance operation according to the balance correction water level.
Preferably, in step S443, the step of causing the washing machine to perform the water filling balance operation according to the balance correction water level gear includes:
s4431, enabling the washing machine to execute water injection operation according to the balance correction water level gear;
s4432, the washing machine is caused to perform a balancing operation according to a preset time threshold.
Further, the preset time threshold is a first preset time threshold under the condition that the total balance correction times is judged to be a first total correction times. For example, the first preset time threshold is 1min, so that the washing machine performs a 1min balancing operation.
Further, in the case that it is determined that the total number of balance corrections is the second total number of corrections, the preset time threshold is the second preset time threshold, and the first preset time threshold is smaller than the second preset time threshold. For example, the second preset time threshold is 2min, so that the washing machine performs a 2min balancing operation.
Further, in a case where it is determined that the total number of balance corrections is the third total number of corrections, the preset time threshold is a third preset time threshold, and the second preset time threshold is smaller than the third preset time threshold. For example, the third preset time threshold is 3min, the washing machine performs a 1min washing operation, and then performs a 2min balancing operation.
Of course, the first preset time threshold, the second preset time threshold and the third preset time threshold are not limited to the above listed times, and those skilled in the art can flexibly adjust and set the first preset time threshold, the second preset time threshold and the third preset time threshold in practical applications.
Preferably, after the step S442 of causing the washing machine to perform the rinsing operation if the current balance correction times are greater than the total balance correction times, the balance correction method further includes:
s444, enabling the washing machine to perform dehydration operation, and detecting whether the washing barrel collides;
s445, if the washing barrel is detected to be collided, the washing machine is enabled to execute alarm operation;
and S446, if the tub collision of the washing tub is not detected, maintaining the current dehydration operation of the washing machine.
Specifically, in step S445, if it is detected that the washing tub collides with the tub, it indicates that the washing machine still cannot uniformly distribute the objects to be washed in the washing tub after the rinsing balance operation is performed, and in order to ensure the safety of the washing machine, the washing machine is put into an alarm mode to prompt the user that the objects to be washed in the washing tub are not uniformly distributed; in step S446, if it is not detected that the washing tub collides, it is considered that the washing machine has uniformly distributed the objects to be washed in the washing tub after the rinsing balance operation is performed, and the washing tub does not generate an asymmetric centrifugal force, and the balance correction is not required, so that the washing machine maintains the current dehydration operation.
Preferably, the washing machine can send alarm information to the user in the form of voice, characters, pictures, light and the like to prompt the user that the objects to be washed in the washing tub are not uniformly distributed.
