The present invention is directed to solving at least one of the problems of the prior art or the related art.
To this end, a first aspect of the present invention proposes a control method of a washing machine.
A second aspect of the present invention proposes a washing machine.
A third aspect of the invention is directed to a readable storage medium.
In view of this, a first aspect of the present invention provides a control method of a washing machine including a tub and a dehydration tub, the control method of the washing machine including: acquiring the dehydration rotating speed of a dehydration barrel, and acquiring the amplitude of the water containing barrel under the condition that the dehydration rotating speed is greater than a first rotating speed threshold value; and determining the variation of the amplitude, and adjusting the dehydration rotating speed according to the variation.
In the technical scheme, the washing machine firstly obtains the rotating speed of the dewatering barrel, namely the dewatering rotating speed, in the dewatering process. And if the dehydration rotating speed is larger than the first rotating speed threshold value, further acquiring the amplitude of the water containing barrel, and adjusting the dehydration rotating speed of the dehydration barrel according to the variable quantity of the amplitude of the water containing barrel.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the dehydration rotation speed rises to a certain threshold value, specifically the first rotation speed threshold value, it represents that the dehydration process has started for a period of time, and at this time, the variation of the amplitude of the water tub is obtained.
In the dewatering process, water adsorbed by clothes in the dewatering barrel is thrown out and finally falls into the water barrel, so that the mass of the dewatering barrel is reduced along with the water in the dewatering barrel entering the water barrel, the mass of the water barrel is increased, the mass change can cause unbalanced motion, and the amplitude of the water barrel is unbalanced, namely the amplitude of the water barrel can show a changed state.
Therefore, according to the amplitude change of the tub, the mass change of the tub can be observed. Specifically, when the amplitude of the water barrel is in a changing trend, the mass of the water barrel and the mass of the dehydration barrel are changed, and the water of the clothes in the dehydration barrel is not dried, so that the dehydration can be kept. And when the amplitude of the water containing barrel tends to be gentle, the quality of the water containing barrel and the quality of the dewatering barrel are approximately unchanged, namely at the current dewatering rotating speed, no water enters the water containing barrel from the dewatering barrel any more, so that the gear of the dewatering rotating speed can be increased at the moment, the next dewatering stage is entered in advance, the phenomenon that the washing machine wastes time at the current dewatering stage, namely at the current dewatering rotating speed, is avoided, and the purpose of saving the dewatering time is achieved.
By applying the technical scheme provided by the invention, after the dehydration rotating speed reaches a certain first rotating speed threshold value, the dehydration rotating speed of the dehydration barrel is adjusted according to the amplitude change of the water containing barrel, so that the time waste caused by the fact that the washing machine maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water out is avoided, the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and the energy can be effectively saved.
In addition, the control method of the washing machine in the above technical solution provided by the present invention may further have the following additional technical features:
in the above technical solution, determining the variation of the amplitude includes: acquiring a first amplitude at a first time; acquiring a second amplitude at a second time which is separated from the first time by a preset time length; the variation is determined based on the difference between the second amplitude and the first amplitude.
In this embodiment, the amplitude variation of the tub may be determined according to a difference between the amplitudes of the tub at the first time and the second time.
Specifically, after the dehydration rotation speed is greater than the first rotation speed threshold, the first amplitude is obtained at the first time, where the "first time" may be any time in the dehydration process, or any time, rather than a fixed time point, and the application does not limit the specific time of the first time.
After the first amplitude is obtained, a second amplitude is obtained at a second time after delaying for a preset time, wherein the second time may be any time or any time in the dehydration process instead of a fixed time point, and the specific time of the second time is not limited in the present application.
According to the difference value of the first amplitude and the second amplitude, the variation of the amplitude of the water containing barrel in the preset time length is obtained through calculation, the dehydration rotating speed of the dehydration barrel is adjusted according to the variation, and the time waste caused by the fact that the washing machine maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw out more water is avoided, so that the dehydration time is effectively shortened, the washing speed and the dehydration speed of the washing machine are improved on the one hand, and on the other hand, energy can be effectively saved.
It can be understood that the amplitude at more time points can be obtained, the amplitude difference values are calculated for a plurality of times, and the variation of the amplitude is determined according to the average value of the difference values finally obtained.
In any one of the above technical solutions, adjusting the dehydration rotation speed according to the variation includes: and controlling the dewatering barrel to improve the dewatering rotating speed according to the comparison result of the variation and a preset variation threshold.
In the technical scheme, the dewatering speed of the dewatering barrel is controlled to be increased by setting a variable quantity threshold value and according to the obtained variable quantity of the amplitude of the water barrel and the comparison result of the variable quantity threshold value. Specifically, when the variation of amplitude satisfies the interval of certain variation threshold, the quality region of current water holding bucket is determined to be stable, then the dehydration effect of the current dehydration stage is judged to have been satisfied, the dehydration rotational speed is improved at this moment, the washing machine is made to enter the next dehydration stage in advance, so that the dehydration rotational speed of the washing machine is improved, and the dehydration time is effectively saved.
In any of the above technical solutions, the rotation speed threshold includes a first threshold, a second threshold and a third threshold, and according to a comparison result between the variation and the preset rotation speed threshold, the spin drying tub is controlled to increase the spin drying speed, which specifically includes:
in the technical scheme, under the condition that the variation is smaller than a first threshold value and is larger than or equal to a second threshold value, the dehydration rotating speed is adjusted to be a first rotating speed; regulating the dehydration rotating speed to a second rotating speed under the condition that the variation is smaller than a second threshold and is larger than or equal to a third threshold; regulating the dehydration rotating speed to a third rotating speed under the condition that the variation is smaller than a third threshold and is larger than or equal to a fourth threshold; the third rotating speed is greater than the second rotating speed, and the second rotating speed is greater than the first rotating speed.
In the technical scheme, the rotation speeds of the first rotation speed, the second rotation speed and the third rotation speed are in increasing trends, under the condition that the variation is between the second threshold and the first threshold, the dehydration work is proved to meet the current stage, the dehydration rotation speed of the current dehydration barrel is increased to the first rotation speed, namely the dehydration rotation speed of the dehydration barrel is controlled to be increased by one gear, and the variation of the amplitude of the dehydration barrel is continuously obtained.
And if the variable quantity is further between the third threshold value and the second threshold value, continuously increasing the dehydration rotating speed of the dehydration barrel, specifically increasing the dehydration rotating speed to the second rotating speed, controlling the rotating speed gear of the dehydration barrel to be increased again, and continuously obtaining the variable quantity of the amplitude of the water barrel.
When the variation is smaller than the third threshold but larger than the fourth threshold, the dewatering speed of the dewatering barrel is increased to the third speed of the highest gear, and the dewatering barrel rotates at a high speed at the moment to ensure the final dewatering effect.
According to the embodiment of the invention, whether the effect of the current dehydration stage is achieved is judged in real time according to the variable quantity of the amplitude of the water containing barrel, and the next dehydration stage is started in advance after the effect is achieved, so that the total dehydration time is shortened, and the time and the energy are saved.
In any of the above technical solutions, the washing machine is controlled to end the dehydration stage when the variation is smaller than the fourth threshold.
In the technical scheme, if the variation of the amplitude of the water containing barrel is smaller than the fourth threshold, the quality of the water containing barrel is basically not changed any more, the dewatering effect can be judged to be achieved at the moment, and the dewatering stage of the washing machine is controlled to be finished, so that the dewatering time can be shortened, the time can be saved, the continuous work of the dewatering barrel of the washing machine under the condition that clothes in the dewatering barrel are dried is avoided, the energy can be saved, and the mechanical loss can be reduced.
In any of the above technical solutions, the washing machine is controlled to end the dehydration stage when the dehydration rotation speed is greater than the first rotation speed threshold and the amplitude is greater than the amplitude threshold.
In the technical scheme, if the dehydration rotating speed of the dehydration barrel is higher than a first rotating speed threshold value and the obtained amplitude of the water containing barrel is larger than a preset amplitude threshold value, the program of the dehydration stage is ended. Specifically, at the beginning of the spin-drying phase, the spin-drying tub is operated at a lower rotation speed, and the spin-drying speed of the spin-drying tub is gradually increased, during which water in the laundry is gradually thrown out and into the tub, which now changes in mass faster, so that the amplitude of the tub is larger.
However, as the spin-drying speed increases, for example, when the spin-drying speed increases above the first spin-drying threshold, it means that the spin-drying process has entered a steady state in which a certain mass of water has been accumulated in the tub, the total mass increases, and therefore the mass increase rate decreases, and the amplitude of the tub should be smaller than the above-mentioned amplitude threshold. And if the amplitude of the water containing barrel is still higher than the amplitude threshold value after the dehydration rotating speed is increased to be higher than the first rotating speed threshold value, the water containing barrel is seriously eccentric, so that the dehydration process of the washing machine is controlled to be finished, and the dehydration stage is finished, so that the use safety of the washing machine is ensured, the washing machine is prevented from being damaged, the noise caused by large eccentricity is avoided, and the mute is favorably realized.
It can be appreciated that after the dehydration stage is finished, the washing machine may start the dehydration again according to the program setting, or after at least one rinsing stage. In some embodiments, if the tub eccentricity continuously occurs, a corresponding alarm prompt may be issued while recording a fault log for reference by a serviceman.
In any of the above technical solutions, the control method of the washing machine further includes: under the conditions that the dehydration rotating speed is less than a first rotating speed threshold value and the amplitude is greater than or equal to an amplitude threshold value, water is supplemented to the water containing barrel; stopping water replenishing to the water containing barrel and improving the dehydration rotating speed under the conditions that the dehydration rotating speed is less than the first rotating speed threshold value and the amplitude is less than the amplitude threshold value until the dehydration rotating speed is more than or equal to the first rotating speed threshold value
In the technical scheme, after the dehydration rotating speed is greater than the second rotating speed threshold value, namely the dehydration state is entered and the first dehydration gear is reached, if the dehydration rotating speed does not reach the first rotating speed threshold value, water can be supplemented to the water containing barrel according to the amplitude of the water containing barrel.
Specifically, the vibration of the tub mainly results from a mass change caused when water enters the tub, and thus the lighter the tub, the more significant the mass change, and the greater the amplitude of the resulting vibration. When the dehydration stage begins and the dehydration speed does not reach the first rotation speed threshold value, because the dehydration stage begins for a short time and enough water is not accumulated in the water barrel, the water barrel is light in weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, according to the amplitude of the water containing barrel, the water supplementing operation is carried out on the water containing barrel, the mass of the water containing barrel can be effectively increased in the initial stage of dehydration, the amplitude of the water containing barrel is reduced, the water containing barrel is prevented from vibrating to emit excessive noise, and the mute dehydration is favorably realized.
Since the vibration of the tub mainly comes from the mass change caused when water enters the tub, the lighter the tub, the more significant the mass change, and the greater the amplitude of the vibration caused. When the dehydration stage begins and the dehydration speed does not reach the first rotation speed threshold value, because the dehydration stage begins for a short time and enough water is not accumulated in the water barrel, the water barrel is light in weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, when the amplitude of the water containing barrel exceeds the amplitude threshold value, the water is filled into the water containing barrel according to a certain flow through a water supplementing algorithm, so that the quality of the water containing barrel is improved, the vibration of the water containing barrel caused by the change of the quality is reduced, the water containing barrel is prevented from vibrating to emit excessive noise, and the mute dehydration is favorably realized.
When the amplitude of water holding bucket was less than the amplitude threshold value, then think that the water holding bucket is comparatively steady, can not produce too big noise, stopped the moisturizing this moment to improve the dehydration rotational speed, make the dehydration get into next dehydration stage, reduce the dehydration time on the one hand, on the other hand can effective energy saving.
In any one of the above technical solutions, the tub is provided with an acceleration sensor to obtain the amplitude of the tub, including: acceleration information in at least three directions is obtained through the acceleration sensor, and the amplitude is determined according to the acceleration information.
In the technical scheme, an acceleration sensor is arranged on the water tub, wherein the acceleration sensor can be an MEMS (Micro-Electro-Mechanical System) acceleration sensor, and can be specifically arranged at the bottom of the water tub. It is to be understood that the acceleration sensor may be another type of acceleration sensor, the number of the acceleration sensors may be one or more, and the set position may be at a position such as a bottom, a side wall, or the like of the tub, which is not limited in the embodiment of the present application.
In the process of acquiring the amplitude of the water tub, the acceleration sensor is used for acquiring a first acceleration, a second acceleration and a third acceleration in three different directions, wherein the three different directions are assumed to be an x direction, a y direction and a z direction respectively, the x direction, the y direction and the z direction can be two linear directions which are mutually perpendicular in pairs, and an xyz coordinate system can be established according to the x direction, the y direction and the z direction.
Through acceleration sensor, acquire acceleration in the x direction, acceleration in the y direction and acceleration in the z direction, can calculate the vibration range in three direction according to above-mentioned acceleration, thereby determine the amplitude of ladle, according to the amplitude change of ladle, adjust the dehydration rotational speed of dehydration bucket, when avoiding that current dehydration rotational speed has can't throw away more water, washing machine still maintains the time waste that current dehydration rotational speed leads to according to fixed procedure, thereby dehydration time has been shortened effectively, improve washing machine's washing on the one hand, dehydration speed, on the other hand can effective energy saving.

When the variation is smaller than the third threshold but larger than the fourth threshold, the dewatering speed of the dewatering barrel is increased to the third speed of the highest gear, and the dewatering barrel rotates at a high speed at the moment to ensure the final dewatering effect.
According to the embodiment of the invention, whether the effect of the current dehydration stage is achieved is judged in real time according to the variable quantity of the amplitude of the water containing barrel, and the next dehydration stage is started in advance after the effect is achieved, so that the total dehydration time is shortened, and the time and the energy are saved.
EXAMPLE five
In some embodiments of the present invention, in case the variation amount is less than the fourth threshold, the washing machine is controlled to end the dehydration stage.
In the embodiment of the invention, if the variation of the amplitude of the water barrel is smaller than the fourth threshold, the quality of the water barrel is basically not changed any more, and at this time, the dewatering effect can be judged to be achieved, and the washing machine is controlled to finish the dewatering stage, so that the dewatering time can be reduced, the time can be saved, the continuous operation of the dewatering barrel of the washing machine under the condition that clothes in the dewatering barrel are dried is avoided, the energy can be saved, and the mechanical loss can be reduced.
EXAMPLE six
In some embodiments of the present invention, the washing machine is controlled to end the spin-drying phase in case the spin-drying speed is greater than the first spin-speed threshold and the amplitude is greater than the amplitude threshold.
In the embodiment of the invention, if the dehydration rotation speed of the dehydration barrel is higher than the first rotation speed threshold value, and the amplitude of the water barrel is obtained to be larger than the preset amplitude threshold value, the dehydration stage process is ended. Specifically, at the beginning of the spin-drying phase, the spin-drying tub is operated at a lower rotation speed, and the spin-drying speed of the spin-drying tub is gradually increased, during which water in the laundry is gradually thrown out and into the tub, which now changes in mass faster, so that the amplitude of the tub is larger.
However, as the spin-drying speed increases, for example, when the spin-drying speed increases above the first spin-drying threshold, it means that the spin-drying process has entered a steady state in which a certain mass of water has been accumulated in the tub, the total mass increases, and therefore the mass increase rate decreases, and the amplitude of the tub should be smaller than the above-mentioned amplitude threshold. And if the amplitude of the water containing barrel is still higher than the amplitude threshold value after the dehydration rotating speed is increased to be higher than the first rotating speed threshold value, the water containing barrel is seriously eccentric, so that the dehydration process of the washing machine is controlled to be finished, and the dehydration stage is finished, so that the use safety of the washing machine is ensured, the washing machine is prevented from being damaged, the noise caused by large eccentricity is avoided, and the mute is favorably realized.
It can be appreciated that the washing machine may start the spinning again according to the program setting after finishing the spinning phase, or restart the spinning after passing at least one rinsing phase. In some embodiments, if the tub eccentricity continuously occurs, a corresponding alarm prompt may be issued while recording a fault log for reference by a serviceman.

In some embodiments of the present invention, fig. 4 illustrates a fourth flowchart of a control method of a washing machine according to an embodiment of the present invention, and specifically, the control method of a washing machine further includes the steps of:
and 404, under the condition that the dehydration rotation speed is greater than or equal to the second rotation speed threshold and smaller than the first rotation speed threshold, replenishing water to the water barrel according to the amplitude.
In the embodiment of the invention, after the dehydration rotating speed is greater than the second rotating speed threshold value, namely the dehydration state is entered and the first dehydration gear is reached, if the dehydration rotating speed does not reach the first rotating speed threshold value, water can be supplemented to the water barrel according to the amplitude of the water barrel.
Specifically, the vibration of the tub mainly results from a mass change caused when water enters the tub, and thus the lighter the tub, the more significant the mass change, and the greater the amplitude of the resulting vibration. And when the dehydration stage begins, and the dehydration rotating speed does not reach the first rotating speed threshold value, because the dehydration stage begins for a short time, enough water has not been accumulated in the water bucket, therefore the water bucket quality is lighter, and the condition of too big amplitude is easy to appear at this moment.
Therefore, according to the amplitude of the water containing barrel, the water supplementing operation is carried out on the water containing barrel, the mass of the water containing barrel can be effectively increased in the initial stage of dehydration, the amplitude of the water containing barrel is reduced, the water containing barrel is prevented from vibrating to emit excessive noise, and the mute dehydration is favorably realized.
Example eight
In some embodiments of the present invention, fig. 5 shows a fifth flowchart of a control method of a laundry machine according to an embodiment of the present invention, in particular, water replenishing of a tub according to an amplitude, including the steps of:
and step 504, under the condition that the amplitude is smaller than the amplitude threshold value, stopping water replenishing to the water containing barrel and increasing the dehydration rotating speed until the dehydration rotating speed is larger than or equal to the first rotating speed threshold value.
In the embodiment of the present invention, since the vibration of the tub is mainly derived from the mass change caused when water enters the tub, the lighter the tub, the more significant the mass change, and the greater the amplitude of the resulting vibration. And when the dehydration stage begins, and the dehydration rotating speed does not reach the first rotating speed threshold value, because the dehydration stage begins for a short time, enough water has not been accumulated in the water bucket, therefore the water bucket quality is lighter, and the condition of too big amplitude is easy to appear at this moment.
Therefore, when the amplitude of the water containing barrel exceeds the amplitude threshold value, the water is filled into the water containing barrel according to a certain flow through a water supplementing algorithm, so that the quality of the water containing barrel is improved, the vibration of the water containing barrel caused by the change of the quality is reduced, the water containing barrel is prevented from vibrating to emit excessive noise, and the mute dehydration is favorably realized.
When the amplitude of steel ladle was less than the amplitude threshold value, then think that the steel ladle is comparatively steady, can not produce too big noise, stopped the moisturizing this moment to improve the dehydration rotational speed, make the dehydration get into next dehydration stage, reduce the dehydration time on the one hand, on the other hand can effective energy saving.
Example nine
In some embodiments of the present invention, an acceleration sensor is provided on the tub to acquire an amplitude of the tub, including: acceleration information in at least three directions is obtained through the acceleration sensor, and the amplitude is determined according to the acceleration information.
In an embodiment of the present invention, an acceleration sensor is disposed on the tub, wherein the acceleration sensor may be configured as a MEMS (Micro-Electro-Mechanical System) acceleration sensor, and may be particularly disposed at the bottom of the tub. It is to be understood that the acceleration sensor may be another type of acceleration sensor, the number of the acceleration sensors may be one or more, and the set position may be at a position such as a bottom, a side wall, or the like of the tub, which is not limited in the embodiment of the present application.
In the process of acquiring the amplitude of the water tub, the acceleration sensor is used for acquiring a first acceleration, a second acceleration and a third acceleration in three different directions, wherein the three different directions are assumed to be an x direction, a y direction and a z direction respectively, the x direction, the y direction and the z direction can be two linear directions which are mutually perpendicular in pairs, and an xyz coordinate system can be established according to the x direction, the y direction and the z direction.
Through acceleration sensor, acquire acceleration in the x direction, acceleration in the y direction and acceleration in the z direction, can calculate the vibration range in three direction according to above-mentioned acceleration, thereby determine the amplitude of ladle, according to the amplitude change of ladle, adjust the dehydration rotational speed of dehydration bucket, when avoiding that current dehydration rotational speed has can't throw away more water, washing machine still maintains the time waste that current dehydration rotational speed leads to according to fixed procedure, thereby dehydration time has been shortened effectively, improve washing machine's washing on the one hand, dehydration speed, on the other hand can effective energy saving.

In some embodiments of the present invention, the dehydration flow of the washing machine includes 6 dehydration stages, each of the dehydration stages corresponds to one dehydration rotation speed, and the dehydration rotation speeds of the 6 dehydration stages are increased step by step. Specifically, for example, the dehydration rotation speed includes the following stages:
a 180rpm phase, a 300rpm phase, a 400rpm phase, a 500rpm phase, a 600rpm phase, and a 700rpm phase.
Fig. 6 shows a sixth flowchart of a control method of a washing machine according to an embodiment of the present invention, and particularly, the flow of dehydration includes:
in step 626, it is determined whether the amplitude variation is smaller than the fourth threshold, if yes, the process is ended, otherwise, the process returns to step 624.
Meanwhile, step 614, step 618, step 622, and step 626 are performed simultaneously to determine whether or not the amplitude exceeds the amplitude threshold, and if the amplitude exceeds the threshold, the process is terminated.
In the embodiment of the invention, the washing machine firstly obtains the rotating speed of the dewatering barrel, namely the dewatering rotating speed in the dewatering process. And if the dehydration rotating speed is larger than the first rotating speed threshold value, further acquiring the amplitude of the water containing barrel, and adjusting the dehydration rotating speed of the dehydration barrel according to the variable quantity of the amplitude of the water containing barrel.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the dehydration rotation speed rises to a certain threshold value, specifically the first rotation speed threshold value, it represents that the dehydration process has started for a period of time, and at this time, the variation of the amplitude of the water tub is obtained.
In the dewatering process, water adsorbed by clothes in the dewatering barrel is thrown out and finally falls into the water barrel, so that the mass of the dewatering barrel is reduced along with the water in the dewatering barrel entering the water barrel, the mass of the water barrel is increased, the mass change can cause unbalanced motion, and the amplitude of the water barrel is unbalanced, namely the amplitude of the water barrel can show a changed state.
Therefore, according to the amplitude change of the tub, the mass change of the tub can be observed. Specifically, when the amplitude of the water barrel is in a changing trend, the mass of the water barrel and the mass of the dehydration barrel are changed, and the water of the clothes in the dehydration barrel is not dried, so that the dehydration can be kept. And when the amplitude of the water containing barrel tends to be gentle, the quality of the water containing barrel and the quality of the dewatering barrel are approximately unchanged, namely, no water enters the water containing barrel from the dewatering barrel at the current dewatering rotating speed, so that the gear of the dewatering rotating speed can be increased at the moment, the next dewatering stage is entered in advance, the phenomenon that the washing machine wastes time at the current dewatering stage, namely, the current dewatering rotating speed is avoided, and the purpose of saving dewatering time is achieved.
Wherein, the rotation speeds of 400rpm, 500rpm, 600rpm and 700rpm are increasing trends, under the condition that the variation is between the second threshold and the first threshold, which indicates that the dewatering work has satisfied the current stage, the dewatering rotation speed of the current dewatering barrel is increased to 500rpm, that is, the dewatering rotation speed of the dewatering barrel is controlled to be increased by one gear, and the variation of the amplitude of the water barrel is continuously obtained.
And if the variable quantity is further between the third threshold value and the second threshold value, continuously increasing the dehydration rotating speed of the dehydration barrel, specifically to 600rpm, controlling the rotating speed gear of the dehydration barrel to be increased again, and continuously acquiring the variable quantity of the amplitude of the water barrel.
When the variation is smaller than the third threshold but larger than the fourth threshold, the dewatering speed of the dewatering barrel is increased to 700rpm of the highest gear, and the dewatering barrel rotates at a high speed at the moment to ensure the final dewatering effect.
According to the embodiment of the invention, whether the effect of the current dehydration stage is achieved is judged in real time according to the variable quantity of the amplitude of the water containing barrel, and the next dehydration stage is started in advance after the effect is achieved, so that the total dehydration time is shortened, and the time and the energy are saved.
By applying the embodiment provided by the invention, after the dehydration rotating speed reaches a certain first rotating speed threshold value, the dehydration rotating speed of the dehydration barrel is adjusted according to the amplitude change of the water containing barrel, so that the time waste caused by the fact that the washing machine maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water out is avoided, the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved on one hand, and the energy can be effectively saved on the other hand.
