Description
Technical Field
The invention relates to the technical field of washing equipment, and particularly provides a control method for washing equipment.
Background
Washing machines are common home laundry washing apparatuses, which are classified according to washing modes, and may be broadly classified into pulsator washing machines and drum washing machines. Taking a pulsator washing machine as an example, when washing operation is performed, clothes are generally washed in a forward and reverse alternate rotation mode, the clothes are entangled together in the washing tub and distributed unevenly, and when the washing machine performs dewatering operation, uneven distribution of the clothes can generate asymmetric centrifugal force on the washing tub, so that the washing tub is severely rocked due to uneven stress, and therefore the washing machine is caused to generate tub collision phenomenon, and noise is generated.
In order to solve the above problems, in the prior art, a balance correction program is set in the pulsator washing machine, and balance water flow instructions are set in the washing program and the balance correction program, and in order to ensure the stability of dehydration before the washing is finished, the clothes in the washing barrel are dispersed and shaken up by running the balance water flow instructions; under the condition that the washing machine collides with the tub, balance correction operation is executed, water is fed to the balance water level, and a balance water flow command is operated to disperse and shake clothes in the washing tub. However, the parameters of the balance water flow instruction in the balance correction process are the same as those of the balance water flow instruction in the washing process, and are fixed, and are not distinguished by the water level or the like, if the balance water flow instruction is used in the washing operation, but the washing machine still generates a tub collision phenomenon when the dewatering operation is performed after the washing operation, which means that the balance water flow instruction in the washing operation does not effectively play a role in washing and shaking the clothes, when the balance correction operation is performed, the balance water flow instruction which continuously adopts the same parameters cannot effectively wash and shake the clothes, and the washing machine may also generate the tub collision phenomenon when the dewatering operation is performed this time after the balance correction operation, thereby influencing the use experience of users.

In a preferred embodiment of the above control method, the step of adjusting the parameter of the balance water flow when the washing apparatus performs the balance operation this time according to the first water level and the second water level further includes: if the second water level interval is higher than the first water level interval, the strength of the balance water flow when the washing equipment executes the balance operation at this time is improved, and the balance time of the balance water flow when the washing equipment executes the balance operation at this time is prolonged.
In the preferred technical scheme of the control method, the washing equipment comprises an inner barrel and a pulsator arranged at the bottom of the inner barrel; the step of improving the strength of the balanced water flow when the washing equipment executes the balancing operation at this time specifically comprises the following steps: when the washing equipment executes the balancing operation, the rotation stop ratio of the pulsator is increased and/or the rotation speed of the pulsator is increased.

Further, if the second water level interval is lower than the first water level interval, it indicates that the water level interval corresponding to the water level of the washing machine when the balancing operation is executed last time and the current balancing operation is changed, and because the parameter requirement of the relatively lower water level interval for the balancing water flow is lower than the parameter requirement of the relatively higher water level interval for the balancing water flow, and the tub bumping phenomenon has occurred after the washing machine executed the balancing operation last time under the condition of the higher first water level interval, it indicates that the parameter of the balancing water flow of the washing machine executed the balancing operation last time is not suitable, if the parameter of the balancing water flow of the washing machine executed the balancing operation this time is adjusted by the relatively lower second water level interval, the adjusted parameter is likely not much changed from the parameter before adjustment, or it is difficult to break up and shake the clothes, and in order to achieve the better balancing effect, the parameter of the balancing water flow of the washing machine executed the current balancing operation is adjusted according to the higher first water level interval.
Further, if the second water level interval is higher than the first water level interval, it indicates that the water level interval corresponding to the water level when the washing machine performs the balancing operation last time and the current performing the balancing operation changes, and because the parameter requirement of the relatively higher water level interval on the balanced water flow is higher than the parameter requirement of the relatively lower water level interval on the balanced water flow, in order to achieve a better balancing effect, the strength of the balanced water flow when the washing machine performs the balancing operation this time is directly improved, and the balancing time of the balanced water flow when the washing machine performs the balancing operation this time is prolonged.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. For example, although the present invention has been described in connection with a washing machine, the technical solution of the present invention is not limited thereto, and the control method may obviously be applied to other washing apparatuses such as a washing and drying machine.
Based on the technical problems in the background art, the invention provides a control method for a washing machine, which aims to adjust parameters of balance water flow when the washing machine executes the balance operation at this time according to a first water level when the washing machine executes the balance operation at last time and a second water level when the washing machine executes the balance operation at this time, so that the balance water flow when the washing machine executes the balance operation at this time can effectively disperse and shake clothes uniformly, the clothes are uniformly distributed in a washing barrel, the phenomenon of barrel collision when the dewatering operation is executed again after the balance operation at this time is avoided, the aim of providing the most reasonable balance water flow for the washing machine executing the balance operation at this time is fulfilled, and further user experience is improved.
Referring to fig. 1 and 2, fig. 1 is a main flow chart of the control method of the present invention; fig. 2 is a complete flow chart of the control method of the present invention.
As shown in fig. 1 and 2, the control method of the present invention includes the steps of:
s100, judging whether the washing machine collides with a barrel or not in the process of executing the dewatering operation of the washing machine;
s200, under the condition that the washing machine collides with a barrel, controlling the washing machine to enter a balancing operation, and acquiring a first water level when the washing machine executes the balancing operation last time and a second water level when the washing machine executes the balancing operation last time;
s300, adjusting parameters of balance water flow when the washing machine executes balance operation at the present time according to the first water level and the second water level.
The balancing operation may be a washing balancing operation in the previous washing operation, a rinsing balancing operation in the previous rinsing operation, or a balancing operation performed after the previous tub collision, or the like.
Preferably, the washing machine includes a cabinet, a washing tub provided in the cabinet, and a safety switch, the washing tub including an outer tub and an inner tub rotatably provided in the outer tub, the safety switch being turned off when the outer tub collides with a control lever of the safety switch.
In step S100, the specific way to determine whether the washing machine collides with the tub may be: acquiring a state of a safety switch, wherein the state of the safety switch comprises an opening state and a closing state of the safety switch; judging whether the safety switch is disconnected; if the safety switch is disconnected, the outer barrel collides with a control rod of the safety switch, so that the safety switch is disconnected, and the washing machine is judged to collide with the barrel; if the safety switch is not opened, the outer barrel is not collided with a control rod of the safety switch, and the safety switch is in a closed state, and the washing machine is judged to be in collision with the barrel.
Or, in an alternative manner, the specific manner of judging whether the washing machine collides with the tub may be: acquiring a first eccentric value of an outer barrel; judging whether the first eccentricity value of the outer barrel is larger than or equal to a first preset eccentricity threshold value; if the first eccentricity value is larger than or equal to a first preset eccentricity threshold value, the eccentricity of the outer barrel is larger, so that the outer barrel collides with the control rod or the box body, and the washing machine is judged to collide with the barrel; if the first eccentricity value is smaller than a first preset eccentricity threshold value, the washing machine is judged to be not collided, and the first eccentricity threshold value is the minimum eccentricity value of the outer barrel, which is judged to be collided with the control rod or the box body, of the outer barrel of the washing machine.
Or, in yet another alternative, the specific way of judging whether the washing machine collides with the tub may be: acquiring a second eccentric value of the rotation of the inner barrel; judging whether the second eccentricity value is larger than or equal to a second preset eccentricity threshold value; because the relative position between the inner barrel and the outer barrel is fixed, the outer barrel is deviated along with the deviation of the inner barrel, when the second eccentric value is larger than or equal to a second preset eccentric threshold value, the rotating eccentric of the inner barrel is larger, and the inner barrel can drive the whole washing barrel to collide with the control rod or the box body; and when the second eccentricity value is smaller than a second preset eccentricity threshold value, judging that the washing machine is not collided, wherein the second eccentricity threshold value is the minimum rotation eccentricity value of the inner barrel of the washing machine, which is used for judging that the inner barrel of the washing machine drives the whole washing body to collide with the control rod or the box body.
Of course, the method for judging whether the washing machine collides with the barrel is not limited to the three listed methods, the instantaneous noise value generated by the washing machine when the washing machine executes the dewatering program can be collected, whether the instantaneous noise value is larger than or equal to the preset noise threshold value is judged, when the instantaneous noise value is larger than or equal to the preset noise threshold value, the collision of the outer barrel with the control rod or the box body is indicated, and huge noise is generated, so that the washing machine is judged to collide with the barrel; when the instantaneous noise value is smaller than a preset noise threshold, the washing machine is judged not to collide with the tub, and the preset noise threshold is the minimum noise, such as 80 dB, generated by the washing machine, for judging that the washing machine collides with the tub. In any case, it is only required to determine that the washing machine collides with the tub.
It should be noted that, the first decentration threshold, the second decentration threshold, and the preset noise threshold are not limited to the above-listed thresholds, but may be decentration thresholds and noise thresholds obtained by a person skilled in the art according to experiments under specific working conditions, or decentration thresholds and noise thresholds obtained according to experience, and no matter what decentration threshold and noise threshold are adopted, it is only required to determine that the washing machine collides with the tub.
In a preferred embodiment, as shown in fig. 2, before the step S100 of "the washing machine performs the dehydration operation", the control method further includes:
s010, enabling the washing machine to execute washing operation;
s020, after the washing machine executes the washing operation, the washing machine is made to execute the dewatering operation.
The washing machine comprises ten-gear water levels, the ten-gear water levels are divided into three water level intervals, wherein the first-gear water level to the third-gear water level are low water level intervals, the fourth-gear water level to the sixth-gear water level are medium water level intervals, and the seventh-gear water level to the ten-gear water level are high water level intervals. Of course, the number of water levels and the division of the water level intervals included in the washing machine are not limited to the above-mentioned cases, and the ten-gear water level may be divided into four water level intervals, the first-gear water level to the second-gear water level are extremely low water level intervals, the third-gear water level to the fourth-gear water level are low water level intervals, the fifth-gear water level to the sixth-gear water level are medium water level intervals, and the seventh-gear water level to the ten-gear water level are high water level intervals; the washing machine may also include eight-gear water levels, dividing the eight-gear water levels into three water level intervals, etc., and those skilled in the art may flexibly adjust and set the number of water levels and the division of the water level intervals in practical applications.
Preferably, the washing machine further comprises a driving motor and a pulsator arranged at the bottom of the inner barrel, wherein the driving motor drives the pulsator to rotate through a clutch, or drives the inner barrel to rotate through the clutch and synchronously drives the pulsator to rotate, and the rotating speeds of the inner barrel and the pulsator are the same.
In step S010, the step of "causing the washing machine to perform the washing operation" specifically includes: in the process of executing the washing operation of the washing machine, for example, before the washing operation is finished, the washing machine executes the washing balance operation according to the parameters of the preset balance water flow, wherein the parameters of the preset balance water flow comprise the intensity of the balance water flow and the balance time, the intensity of the preset balance water flow and the balance time are determined according to the washing water level of the washing machine, for example, the intensity of the balance water flow of the washing machine can be reflected through the rotation stop ratio of the pulsator, and when the washing water level is in a low water level interval, the rotation stop ratio of the pulsator is 0.3/0.5, and the balance time is 30s; when the washing water level is in the middle water level interval, the rotation stop ratio of the pulsator is 0.4/0.5, and the balancing time is 40s; when the washing water level is in the high water level interval, the rotation stop ratio of the pulsator is 0.5/0.5, and the balancing time is 60s. The intensity of the balance water flow of the washing machine can be reflected by the rotating speed of the pulsator, and when the washing water level is in a low water level interval, the rotating speed of the pulsator is 90rpm; when the washing water level is in the middle water level interval, the rotating speed of the pulsator is 95rpm; when the washing water level is in the high water level interval, the rotation speed of the pulsator is 100rpm. The above-described rotation stop ratio, rotation speed, and balancing time of the pulsator are only exemplary, and not restrictive, and those skilled in the art can adjust the intensity of the balancing water flow and the balancing time according to the washing water level in practical applications. Of course, the parameters may also include only the intensity of the balanced water flow or the balancing time, and the person skilled in the art can flexibly adjust and set the parameters.
It should be noted that, the person skilled in the art may use not only the parameter of the preset balance water flow as the reference parameter of the balance water flow of the washing balancing operation, but also the parameter of the preset balance water flow as the reference parameter of the balance water flow of the rinsing balancing operation performed after the washing operation, the reference parameter of the balance water flow of the balancing operation performed after the dewatering and the bumping into the tub, or the reference parameter of the balance water flow of the balancing operation performed in other cases, that is, the reference parameter of the balance water flow in any case, is the same. The reference parameter is a parameter before balance water flow adjustment described below.
Or, in an alternative manner, before step S100, the control method further includes: causing the washing machine to perform a rinsing operation; after the washing machine performs the rinsing operation, the washing machine is made to perform the dehydrating operation.
Wherein, the step of "causing the washing machine to perform the rinsing operation" specifically includes: in the course of the rinsing operation performed by the washing machine, for example, before the rinsing operation is finished, the washing machine is made to perform a rinsing balance operation according to a preset balance water flow parameter, wherein the preset balance water flow parameter includes a balance water flow intensity and a balance time, and the preset balance water flow intensity and the balance time are determined according to a rinsing water level of the washing machine. In addition, the specific determination method of the preset balance water flow strength and balance time may refer to the corresponding description in step S010, and will not be described herein.
Similarly to the above, the person skilled in the art may use not only the parameter of the preset balance water flow as the reference parameter of the balance water flow of the rinsing balance operation, but also the parameter of the preset balance water flow as the reference parameter of the balance water flow of the balance operation performed in other cases such as the reference parameter of the balance water flow of the balance operation performed after the dewatering drum collision, that is, the reference parameter of the balance water flow in any case is the same. The reference parameter is a parameter before balance water flow adjustment described below.
Or, in yet another alternative, before step S100, the control method further includes: causing the washing machine to perform a washing operation; after the washing machine performs the washing operation, causing the washing machine to perform a first dehydrating operation; after the washing machine performs the first dehydrating operation, causing the washing machine to perform a rinsing operation; after the washing machine performs the rinsing operation, the washing machine is caused to perform the second dehydrating operation. Wherein the number of the first and second dehydration operations may be one or more times.
The parameters of the preset balance water flow can be determined according to the washing water level of the washing machine, or can be determined according to the rinsing water level of the washing machine, and the parameters of the balance water flow can be determined according to the washing water level or the rinsing water level, so long as the determined parameters of the balance water flow are used as the reference parameters of the balance water flow of the washing balance operation, the reference parameters of the balance water flow of the rinsing balance operation performed after the washing operation, the reference parameters of the balance water flow of the balance operation performed under other conditions such as the reference parameters of the balance water flow of the balance operation performed after the dewatering collision of the tub, and the like, namely, the reference parameters of the balance water flow in any condition are the same.
Of course, the parameter of the balance water flow determined according to the wash water level may be used as a reference parameter of the balance water flow of the wash balancing operation, and a reference parameter of the balance water flow of the balancing operation performed between the wash operation and the rinse operation; the parameter of the balance water flow determined according to the rinsing water level is taken as a reference parameter of the balance water flow of the rinsing balance operation, a reference parameter of the balance water flow of the balance operation performed after the rinsing operation, and the like. The reference parameter is a parameter before balance water flow adjustment described below. In addition, the specific determination method of the parameters of the preset balance water flow (i.e. the strength and the balance time of the balance water flow) may refer to the corresponding description in step S010, and will not be repeated here.
In the above three embodiments, the washing water level and the rinsing water level may be the water level set by the user, or may be the water level determined by the washing machine according to the information such as the weight of the laundry, or may be the water level corresponding to the washing program recommended by the washing machine, which may be flexibly adjusted and set by those skilled in the art in practical application.
The control method of adjusting the parameters of the balance water flow when the washing machine performs the balancing operation this time according to the present invention will be described with reference to fig. 3. Fig. 3 is a flowchart of a control method for adjusting parameters of balance water flow when the washing machine performs a balancing operation at this time according to the present invention. In fig. 3, a ten-gear water level and three water level intervals are taken as examples, namely, a low water level interval from a first-gear water level to a third-gear water level, a medium water level interval from a fourth-gear water level to a sixth-gear water level, and a high water level interval from a seventh-gear water level to a ten-gear water level are taken as examples, so that the control method of the present invention is further described.
In step S300, the step of adjusting the parameters of the balance water flow when the washing machine performs the balancing operation at this time according to the first water level and the second water level specifically includes:
s310, determining a first water level interval where the first water level is located according to the first water level;
s320, determining a second water level interval where the second water level is located according to the second water level;
s330, judging whether the second water level interval is lower than or equal to the first water level interval;
s340, if the second water level interval is higher than the first water level interval, improving the strength of the balanced water flow when the washing machine executes the balancing operation, and prolonging the balancing time of the balanced water flow when the washing machine executes the balancing operation;
and if the second water level interval is lower than or equal to the first water level interval, adjusting parameters of balance water flow when the washing machine executes balance operation according to the first water level interval.
In step S310 and step S320, for example, the first water level is a third water level, and then the first water level is in a low water level interval; the first water level is a five-gear water level, and then the first water level is in a middle water level interval; the first water level is seven-gear, and then the first water level is in a high water level interval; correspondingly, the second water level is a second-gear water level, and then the second water level is in a low water level interval; the second water level is a six-gear water level, and then the second water level is in a middle water level interval; the second water level is an eight-gear water level, and then the second water level is in a high water level interval, namely, the water level interval corresponding to the first water level and the second water level can be determined according to the water level gear corresponding to the first water level and the second water level.
In step S330, the first water level interval in which the first water level is located and the second water level interval in which the second water level is located are compared, for example, if the first water level is in the middle water level interval, the second water level interval in which the second water level is located is determined to be equal to the first water level interval in which the first water level is located if the second water level is also in the middle water level interval; if the second water level is in the low water level interval, judging that the second water level interval in which the second water level is positioned is lower than the first water level interval in which the first water level is positioned; if the second water level is in the high water level interval, the second water level interval in which the second water level is positioned is judged to be higher than the first water level interval in which the first water level is positioned, namely, the low water level interval is lower than the middle water level interval, the middle water level interval is lower than the high water level interval, and the water level intervals are judged to be equal when the second water level is in the same water level interval.
In step S340, if the second water level interval is higher than the first water level interval, for example, the first water level is in the middle water level interval, and the second water level is in the high water level interval, which indicates that the water level interval corresponding to the water level when the balancing operation was performed last time and this time of the balancing operation is changed, and because the parameter requirement of the high water level interval on the balanced water flow is higher than the parameter requirement of the middle water level interval on the balanced water flow, for example, the parameters of the balanced water flow in the middle water level interval are: the rotation-stop ratio of the impeller is 0.4/0.5, and the balancing time is 40s; the parameters of the balanced water flow in the high water level interval are: the rotation stop ratio of the impeller is 0.5/0.5, and the balancing time is 60s. Therefore, in order to achieve better balance effect, the strength of the balance water flow when the washing machine executes the balance operation at this time is directly improved, and the balance time of the balance water flow when the washing machine executes the balance operation at this time is prolonged.
Further, if the second water level interval is equal to the first water level interval, for example, the first water level and the second water level are both in the middle water level interval, which means that the water level intervals corresponding to the water level when the washing machine last performed the balancing operation and the current performed the balancing operation are the same, in the same water level interval, different water levels have little influence on the balancing effect of the balancing water flow, and the parameters of the balancing water flow corresponding to the different water levels are the same, so that the parameters of the balancing water flow when the washing machine currently performed the balancing operation can be adjusted according to the first water level interval. Of course, the parameters of the balance water flow when the washing machine performs the balance operation this time may be adjusted according to the second water level interval.
Further, if the second water level interval is lower than the first water level interval, for example, the first water level is in the middle water level interval, and the second water level is in the low water level interval, which indicates that the water level interval corresponding to the water level when the washing machine last performed the balancing operation and this time performed the balancing operation changes, and because the parameter requirement of the low water level interval on the balanced water flow is lower than the parameter requirement of the middle water level interval on the balanced water flow, for example, the parameters of the balanced water flow in the middle water level interval are: the rotation-stop ratio of the impeller is 0.4/0.5, and the balancing time is 40s; the parameters of the balanced water flow in the low water level interval are: the rotation-stop ratio of the impeller is 0.3/0.5, and the balancing time is 30s; in addition, the phenomenon of barrel collision occurs after the washing machine performs the balancing operation last time under the condition of a higher middle water level interval, which indicates that parameters of the balancing water flow when the washing machine performs the balancing operation last time are unsuitable, and if the parameters of the balancing water flow when the washing machine performs the balancing operation this time are adjusted in a relatively lower low water level interval, the adjusted parameters are likely to have little change with the parameters before adjustment, or the clothes are difficult to be scattered and shaken up. Therefore, in order to achieve a better balancing effect, the parameters of the balancing water flow when the washing machine performs the balancing operation this time are adjusted according to the higher middle water level interval (i.e. the first water level interval).
In the above-described process, the execution sequence of step S310 and step S320 is not limited to the above-described sequence, and step S320 may be executed first and then step S310 may be executed, or step S310 and step S320 may be executed simultaneously, which is not limited in the present invention.
In the above process, "increase the intensity of the balanced water flow when the washing machine performs the balancing operation this time, and extend the balancing time of the balanced water flow when the washing machine performs the balancing operation this time" and "adjust the parameters of the balanced water flow when the washing machine performs the balancing operation this time according to the first water level interval" do not have a sequential order, and are parallel, only related to the determination result of whether the second water level interval is lower than or equal to the first water level interval, and execute the corresponding steps according to different determination results.
Preferably, as shown in fig. 3, the step of adjusting the parameter of the balance water flow when the washing machine performs the balancing operation according to the first water level interval specifically includes:
s351, if the first water level interval is a high water level interval, improving the strength of balanced water flow when the washing machine executes the balancing operation, and prolonging the balancing time of the balanced water flow when the washing machine executes the balancing operation;
S352, if the first water level interval is a middle water level interval, the balance time of the balance water flow when the washing machine executes the balance operation at this time is not adjusted, but the strength of the balance water flow when the washing machine executes the balance operation at this time is improved;
s353, if the first water level interval is a low water level interval, the intensity of the balance water flow when the washing machine performs the balancing operation this time is not adjusted, but the balancing time of the balance water flow when the washing machine performs the balancing operation this time is prolonged.
In step S351, if the first water level interval is a high water level interval, it is indicated that the first water level is higher, the intensity of the balance water flow is insufficient and the balancing time is shorter when the washing machine performs the balancing operation last time, and the laundry is not effectively dispersed and shaken up, so that the washing machine is in a tub collision phenomenon, therefore, the intensity of the rinsing balance water flow needs to be improved, and the balancing time of the rinsing balance water flow needs to be prolonged, so that the adjusted balance water flow can effectively disperse and shake the laundry, and the tub collision phenomenon is avoided when the dewatering operation is performed again after the balancing operation.
In step S352, if the first water level interval is the middle water level interval, it is indicated that the first water level is moderate, the balancing time of the washing machine when the balancing operation is executed last time is enough, but the strength of the balancing water flow is slightly weak, so that most of the clothes can be dispersed and shaken up, or a small part of the clothes can not be dispersed and shaken up, so that the washing machine is in a tub collision phenomenon, and if the strength of the balancing water flow is moderate, the balancing time is prolonged for a long time to effectively disperse and shake up all the clothes, so as to shorten the total running time of the washing machine, the strength of the balancing water flow when the balancing operation is executed this time of the washing machine is improved, but the balancing time of the balancing water flow when the balancing operation is executed this time of the washing machine is not prolonged, so that the adjusted balancing water flow can effectively disperse and shake up the clothes, and the tub collision phenomenon when the dewatering operation is executed again after the balancing operation is executed this time is avoided.
In step S353, if the first water level interval is a low water level interval, it is indicated that the first water level interval is lower, the intensity of the balance water flow when the balancing operation is performed last time by the washing machine is sufficient, but the balancing time is slightly short, so that most of the clothes can be dispersed and shaken up, or a small portion of the clothes can not be dispersed and shaken up, so that the washing machine has a tub collision phenomenon, and in the case of lower water level, the intensity of the balance water flow is increased, the splashing situation is unfavorable for dispersing and shaking up the clothes, therefore, the balancing time of the balance water flow when the balancing operation is performed this time by the washing machine is only required to be prolonged, the intensity of the balance water flow when the balancing operation is performed this time by the washing machine is not required to be adjusted, so that the adjusted balance water flow can effectively disperse and shake up the clothes, and the tub collision phenomenon when the dewatering operation is performed again after the balancing operation is performed this time is avoided.
Further, in the above process, the extended balancing time of the balancing water flow when the washing machine performs the balancing operation at this time may be determined according to the correspondence between the information such as the first water level interval and the extended balancing time, for example, in step S340, the first water level interval is a middle water level interval, the second water level interval is a high water level interval, and the balancing time before adjustment is 60S based on the second water level interval, and at this time, the balancing time of the balancing water flow when the washing machine performs the balancing operation at this time is extended by 10S according to the first water level interval; for another example, in step S351, the first water level interval is a high water level interval, the second water level interval is a high water level interval, and the balancing time before adjustment is 60S based on the second water level interval, and the balancing time of the balancing water flow when the washing machine performs the balancing operation at this time is prolonged by 10S according to the first water level interval; for another example, in step S353, the first water level interval is a low water level interval, and the second water level interval is a low water level interval, and the balancing time before adjustment is 30S, and the balancing time of the balancing water flow when the washing machine performs the balancing operation at this time may be prolonged by 8S according to the first water level interval.
Further, in step S340, step S351 and step S352, the strength of the balanced water flow when the balancing operation is performed this time by increasing the rotation stop ratio of the pulsator, for example, the first water level interval is a middle water level interval, the rotation stop ratio before the pulsator is adjusted is 0.4/0.5, the rotation time of the pulsator is increased, and the rotation stop ratio is adjusted to be 0.5/0.5; or reducing the stop time of the pulsator, and adjusting the rotation stop ratio to 0.4/0.4; or the rotation time of the pulsator is increased, the stop time of the pulsator is reduced, the rotation-stop ratio is adjusted to be 0.5/0.4, and the strength of balanced water flow when the washing machine executes the balancing operation at the time is improved through the mode.
Or, the intensity of the balance water flow when the washing machine performs the balance operation this time is improved by improving the rotation speed of the pulsator, for example, the first water level interval is a low water level interval, the rotation speed before the pulsator is adjusted is 90rpm, and the rotation speed of the pulsator is improved to 94rpm, so that the intensity of the balance water flow when the washing machine performs the balance operation this time is improved.
Or, the intensity of the balanced water flow when the washing machine performs the balancing operation this time is improved by increasing the rotation stop ratio of the pulsator and increasing the rotation speed of the pulsator, for example, the first water level interval is a high water level interval, the rotation stop ratio before the pulsator is adjusted is 0.5/0.5, the rotation speed before the pulsator is adjusted is 100rpm, the rotation time of the pulsator is increased, the rotation stop ratio is adjusted to 0.6/0.5, and the rotation speed of the pulsator is increased to 103rpm; or reducing the stopping time of the pulsator, adjusting the rotation stopping ratio to 0.5/0.4, and increasing the rotating speed of the pulsator to 109rpm; or the rotation time of the pulsator is increased, the stop time of the pulsator is reduced, the rotation-stop ratio is adjusted to be 0.6/0.4, the rotating speed of the pulsator is increased to 106rpm, and the strength of balanced water flow when the washing machine executes the balancing operation at the time is improved through the mode.
It should be noted that, the balancing time before adjustment and the balancing time after adjustment in the above-listed washing machine performing the balancing operation at this time, the rotation stop ratio before adjustment of the pulsator, the rotation speed before adjustment, the rotation stop ratio after adjustment, and the rotation speed after adjustment are merely exemplary, and not limitative, and those skilled in the art can adjust the balancing time and the strength of the washing machine performing the balancing operation at this time according to the first water level interval and the second water level interval in practical applications.
In addition, as will be appreciated by those skilled in the art, since the driving motor is used to drive the pulsator, the intensity of the balancing water flow when the washing machine performs the balancing operation this time may also be adjusted by adjusting the rotation stop ratio and/or the rotation speed of the driving motor, and the specific adjustment manner may refer to the corresponding descriptions in step S010, step S340, step S351 and step S352, which will not be repeated here.
In the above process, the steps S351 to S353 are not sequentially performed, and are parallel, and only the specific water level interval in which the first water level interval is located is related, and the corresponding steps are executed according to different water level intervals.
Referring again to fig. 2 in conjunction with fig. 3, after step S300 in fig. 2, or step S340, step S351 to step S353 in fig. 3, the control method further includes:
S410, in the process of executing the balancing operation of the washing machine, the washing machine executes the balancing operation according to the adjusted parameters of the balancing water flow.
Further, as shown in fig. 2, the control method further includes:
s420, under the condition that the washing machine does not collide with a barrel, when the washing machine executes balancing operation again, the washing machine executes balancing operation according to the parameters of the balancing water flow when the balancing operation is executed last time; the balancing operation performed again by the washing machine may be a rinsing balancing operation, etc., and the balancing operation performed last time by the washing machine may be a washing balancing operation, a balancing operation performed after the spin-drying and the tub-bumping, etc.
In step S420, after the washing balancing operation or the balancing operation performed after the dewatering and bumping operation is performed last time, the parameters of the balancing water flow indicating the washing balancing operation or the balancing operation performed after the dewatering and bumping operation are appropriate, so that the laundry can be effectively dispersed and shaken up.
Or, in an alternative manner, the control method further includes:
when the washing machine executes balancing operation again under the condition that the washing machine does not collide with the barrel, the washing machine executes balancing operation according to the parameters of preset balancing water flow; the balancing operation performed again by the washing machine may be a rinsing balancing operation, the balancing operation performed last time by the washing machine may be a washing balancing operation, etc.
Specifically, in the process of performing the dewatering operation after the washing balance operation is performed last time by the washing machine, the tub collision does not occur, so that the parameters of the preset balance water flow are proper, clothes can be effectively dispersed and shaken up, and the parameters of the preset rinsing balance water flow are the same as those of the preset washing balance water flow, so that when the rinsing balance operation is performed, the clothes can be effectively dispersed and shaken up by adopting the rinsing balance water flow which is the same as that of the washing balance water flow, and the washing machine can directly perform the balance operation according to the parameters of the preset balance water flow.
In the above process, the parameters before the balance water flow adjustment of the balance operation, such as the washing balance operation, the rinsing balance operation, or the balance operation performed under other conditions such as the tub collision operation, may be parameters determined according to the washing water level or the rinsing digit, or parameters of the washing machine itself; if the parameters are parameters of the washing machine, the parameters before balance water flow adjustment of the balance operation, such as the washing balance operation, the rinsing balance operation, the balance operation after the tub collision, and the like are the same, and the parameters are fixed and are not distinguished by the water level, and the like.
