Description

Control method of washing machine, washing machine and readable storage medium
Technical Field
The present application relates to the technical field of washing machines, and in particular, to a control method of a washing machine, and a readable storage medium.
Background
In the related art, there are several rinsing and dehydrating stages of the pulsator washing machine during the washing process, wherein the dehydrating stages are performed according to a set program, parameters such as a dehydrating time and a dehydrating rotation speed are fixed, and when the tub is eccentric, the operation according to the fixed dehydrating rotation speed causes an increase of dehydrating noise, thereby affecting the experience.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems existing in the prior art or 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 proposes a readable storage medium.
In view of the above, a first aspect of the present invention provides a control method of a washing machine including a tub and a dehydrating tub, the control method of the washing machine including: acquiring a dehydration rotating speed of the dehydration barrel, and acquiring the amplitude of the water holding barrel under the condition that the dehydration rotating speed is greater than or equal to a first rotating speed threshold value; and when the amplitude is larger than the amplitude threshold value, reducing the dehydration rotating speed until the dehydration is finished.
In the technical scheme, the washing machine firstly obtains the rotation speed of the dewatering barrel, namely the dewatering rotation speed, in the dewatering process. If the dehydration rotation speed is greater than the first rotation speed threshold value, further acquiring the amplitude of the water containing bucket, and adjusting the dehydration rotation speed of the dehydration bucket according to the amplitude of the water containing bucket.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the spin speed increases to a certain threshold, specifically a first spin speed threshold, it means that the spin state of the washing machine has reached the maximum spin speed, and the amplitude of the tub is obtained at this time.
Wherein, in the dehydration process, water adsorbed by clothes in the dehydration barrel is 'thrown' out and finally falls into the water containing barrel, so as the water in the dehydration barrel enters the water containing barrel, the quality of the dehydration barrel is reduced, the quality of the water containing barrel is increased, the quality change can lead to unbalanced movement of the water containing barrel, and the phenomenon of amplitude change is caused, thereby noise is formed. While a higher spin rate represents a spin process closer to the tail while being more prone to noise.
Therefore, the embodiment of the application can judge whether the water holding barrel generates extra noise in the dewatering ending stage according to the amplitude of the water holding barrel, dynamically adjust the dewatering rotating speed of the dewatering barrel according to the real-time amplitude of the water holding barrel, and avoid the noise of the water holding barrel by adjusting the dewatering rotating speed when the amplitude is larger, thereby being beneficial to realizing mute dewatering.
In addition, the control method of the washing machine in the technical scheme provided by the application can also have the following additional technical characteristics:
in the above technical solution, the control method of the washing machine further includes: and under the condition that the dehydration rotating speed is larger than or equal to the second rotating speed threshold value and smaller than the first rotating speed threshold value, 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 rotation speed of the dewatering barrel, namely the dewatering rotation speed, in the dewatering process. If the dehydration rotation speed is greater than the second rotation speed threshold value but less than the first rotation speed threshold value, further acquiring the amplitude of the water bucket, and adjusting the dehydration rotation speed of the dehydration bucket according to the variation of the amplitude of the water bucket.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the dehydration rotation speed is increased to the second rotation speed threshold value, it represents that the dehydration process has been started for a while, and the variation of the amplitude of the tub is acquired.
In the dehydration process, water adsorbed by clothes in the dehydration barrel is thrown out and finally falls into the water containing barrel, so that the quality of the dehydration barrel is reduced as the water of the dehydration barrel enters the water containing barrel, the quality of the water containing barrel is increased, and the quality is changed, so that movement is unbalanced, and the amplitude of the water containing barrel is unbalanced, namely, the amplitude of the water containing barrel is changed.
Therefore, the change in the mass of the tub can be observed based on the change in the amplitude of the tub. Specifically, when the amplitude of the tub is in a trend of variation, it is indicated that the quality of both the tub and the dehydrating tub is changed, and at this time, the water of the laundry in the dehydrating tub is not "spin-dried", so that the progress of the dehydration can be maintained. When the amplitude of the water holding barrel tends to be gentle, the quality of the water holding barrel and the quality of the dewatering barrel are approximately unchanged, namely, under the current dewatering rotating speed, no water enters the water holding barrel from the dewatering barrel, so that the gear of the dewatering rotating speed can be increased, the next dewatering stage can be advanced, the phenomenon that the washing machine wastes time in the current dewatering stage, namely, 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 application, the dehydration rotating speed of the dehydration barrel is regulated according to the amplitude change of the water containing barrel, so that the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water 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 any of the above embodiments, determining the amount of change in the amplitude includes: acquiring a first amplitude at a first moment; acquiring a second amplitude at a second time interval which is a preset duration from the first time interval; the amount of change is determined based on the difference between the second amplitude and the first amplitude.
In this aspect, the amplitude variation amount of the tub may be determined according to a difference in amplitude of the tub at the first time and at the second time.
Specifically, when the dehydration rotation speed is greater than the second rotation speed threshold, the first amplitude is acquired at a first moment, wherein the "first moment" can be any moment in the dehydration process or any moment, but is not a fixed time point, and the specific time of the first moment is not limited by the present application.
After the first amplitude is obtained, the second amplitude is obtained at a second moment after a delay preset time, wherein the second moment can be any moment in the dehydration process or any moment, but is not a fixed time point, and the specific time of the second moment is not limited by the application.
According to the difference value of the first amplitude and the second amplitude, the variation of the amplitude of the water holding barrel in the preset time period is calculated, the dehydration rotating speed of the dehydration barrel is regulated according to the variation, and the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water is avoided, so that the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and energy sources can be effectively saved.
It can be understood that the amplitude at more time points can be obtained, the amplitude difference value is calculated for a plurality of times, and the variation of the amplitude is determined according to the average value of the obtained plurality of difference values.
In any of the above technical solutions, adjusting the dehydration rotation speed according to the variation includes: and controlling the dewatering barrel to increase the dewatering rotating speed according to the comparison result of the variation and the preset variation threshold.
In the technical scheme, the dehydration barrel is controlled to increase the dehydration rotating speed by setting a variation threshold and according to the obtained variation of the amplitude of the water barrel and the comparison result of the variation threshold. Specifically, when the variation of the amplitude meets the interval of a certain variation threshold, the quality area of the current water holding barrel is considered to be stable, the dewatering effect of the current dewatering stage is judged to be met, and the dewatering rotation speed is increased at the moment, so that the washing machine enters the next dewatering stage in advance, the dewatering rotation speed of the washing machine is increased, and the dewatering time is effectively saved.
In any one 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 variable quantity and a preset rotation speed threshold, the dewatering barrel is controlled to increase the dewatering rotation speed, which specifically includes:
in the technical scheme, under the condition that the variation is smaller than a first threshold value and larger than or equal to a second threshold value, the dehydration rotating speed is regulated to be a first rotating speed; when the variation is smaller than the second threshold value and larger than or equal to the third threshold value, the dehydration rotating speed is adjusted to be the second rotating speed; when the variation is smaller than the third threshold value and larger than or equal to the fourth threshold value, the dehydration rotating speed is adjusted to be the third rotating speed; the first rotation speed threshold value is equal to a third rotation speed, the third rotation speed is larger than the second rotation speed, and the second rotation speed is larger than the first rotation speed.
In the technical scheme, the rotation speeds of the first rotation speed, the second rotation speed and the third rotation speed are in an increasing trend, and under the condition that the variation is between the second threshold value and the first threshold value, the dehydration work is satisfied in 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 water holding barrel is continuously obtained.
If the variation is further between the third threshold value and the second threshold value, the dehydration rotating speed of the dehydration barrel is continuously increased, specifically to the second rotating speed, the rotating speed gear lifting of the dehydration barrel is controlled again, and the variation of the amplitude of the water containing barrel is continuously obtained.
When the variation is smaller than the third threshold value but larger than the fourth threshold value, the dehydration rotating speed of the dehydration barrel is increased to the third rotating speed of the highest gear, and the dehydration barrel rotates at a high speed at the moment so as to ensure the final dehydration 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 variation of the amplitude of the water containing bucket, and the next dehydration stage is advanced after the effect is achieved, so that the total dehydration time is reduced, and the time and energy conservation are realized.
In any of the above embodiments, the washing machine is controlled to end the dehydration stage if 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 value, the quality of the water containing barrel is basically not changed, at the moment, the dewatering effect can be judged to be achieved, and the washing machine is controlled to finish the dewatering stage, so that on one hand, the dewatering time can be reduced, on the other hand, the time can be saved, on the other hand, the condition that the dewatering barrel of the washing machine continuously works under the condition that clothes in the dewatering barrel are dried is avoided, and energy can be saved and mechanical loss can be reduced.
In any of the above technical solutions, when the dehydration rotation speed is greater than the second rotation speed threshold value and the amplitude is greater than the amplitude threshold value, the washing machine is controlled to end the dehydration stage.
In the technical scheme, if the dehydration rotation speed of the dehydration barrel is higher than the second rotation speed threshold value, and the amplitude of the water containing barrel is obtained to be larger than the preset amplitude threshold value, ending the dehydration stage. Specifically, at the beginning of the dehydration stage, the dehydration tub is operated at a lower rotational speed, and the dehydration rotational speed of the dehydration tub is gradually increased, in which process water in laundry is gradually thrown out and enters the tub, and the tub is rapidly changed in mass at this time, so that the amplitude of the tub is large.
However, as the dehydration speed increases gradually, for example, when the dehydration speed increases above the second speed threshold, it means that the dehydration process has entered a steady state in which a certain mass of water has been accumulated in the tub, and the total mass increases, so that the mass increase ratio decreases, and the amplitude of the tub should be less than the amplitude threshold. If the amplitude of the water bucket is still higher than the amplitude threshold after the dehydration rotating speed is increased to be higher than the second rotating speed threshold, the serious eccentricity of the water bucket is indicated, so that the washing machine is controlled to finish the dehydration process and the dehydration stage, thereby ensuring the use safety of the washing machine, preventing the washing machine from being damaged, avoiding the noise increase caused by the large eccentricity, and being beneficial to realizing silence.
It can be appreciated that the washing machine may start the dehydration again according to the program setting after the end of the dehydration phase, or restart the dehydration after at least one rinsing phase. In some embodiments, if the eccentricity of the tub occurs continuously, a corresponding alarm prompt may be issued while recording a fault log for reference by a serviceman.
In any of the above technical solutions, when the dehydration rotation speed is less than the second rotation speed threshold and the amplitude is greater than or equal to the amplitude threshold, water is replenished to the water tub; and under the condition that the dehydration rotating speed is smaller than the first rotating speed threshold value and the amplitude is smaller than the amplitude threshold value, stopping water supplementing to the water bucket and increasing the dehydration rotating speed until the dehydration rotating speed is larger than or equal to the second rotating speed threshold value.
In the technical scheme, after the dehydration rotation speed is greater than the third rotation speed threshold, namely the dehydration state is entered and the first dehydration gear is reached, if the dehydration rotation speed does not reach the second rotation speed threshold, the water can be supplemented to the water bucket according to the amplitude of the water bucket.
Specifically, the vibration of the tub is mainly due to the mass change caused when water enters the tub, so the lighter the tub, the more remarkable the mass change, and the larger the resulting vibration amplitude. When the dehydration rotation speed does not reach the second rotation speed threshold value at the beginning of the dehydration stage, because the dehydration stage has short beginning time, enough water is not accumulated in the water bucket, so the water bucket has lighter weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, the water bucket is subjected to water supplementing operation according to the amplitude of the water bucket, so that the mass of the water bucket can be effectively increased in the initial stage of dehydration, the amplitude of the water bucket is reduced, excessive noise generated by vibration of the water bucket is avoided, and mute dehydration is facilitated.
Since the vibration of the tub is mainly due to the mass change caused when water enters the tub, the lighter the tub, the more remarkable the mass change, and the larger the resulting vibration amplitude. When the dehydration rotation speed does not reach the second rotation speed threshold value at the beginning of the dehydration stage, because the dehydration stage has short beginning time, enough water is not accumulated in the water bucket, so the water bucket has lighter weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, when the amplitude of the water holding barrel exceeds the amplitude threshold value, clean water is injected into the water holding barrel according to a certain flow through a water supplementing algorithm, so that the quality of the water holding barrel is improved, the vibration of the water holding barrel caused by the change of the quality is reduced, the excessive noise generated by the vibration of the water holding barrel is avoided, and the mute dehydration is facilitated.
When the amplitude of the water holding bucket is smaller than the amplitude threshold value, the water holding bucket is considered to be stable, excessive noise is not generated, water replenishing is stopped at the moment, the dehydration rotating speed is increased, dehydration enters the next dehydration stage, on one hand, the dehydration time is reduced, and on the other hand, energy sources can be effectively saved.
In any of the above technical solutions, an acceleration sensor is provided on the tub, to obtain an amplitude of the tub, including: acceleration information in at least three directions is acquired through an acceleration sensor, and the amplitude is determined according to the acceleration information.
In this technical solution, an acceleration sensor is provided on the tub, wherein the acceleration sensor may be provided as a MEMS (Micro-Electro-Mechanical System ) acceleration sensor, and may be specifically provided at the bottom of the tub. It can be understood that the acceleration sensor may be other types of acceleration sensors, the number of the acceleration sensors may be one or more, and the setting positions may be at the bottom, the side wall, etc. of the tub, which is not limited in the embodiment of the present application.
In the process of acquiring the amplitude of the tub, the first acceleration, the second acceleration and the third acceleration in three different directions are acquired through the acceleration sensor, and it is assumed that the three different directions are an x direction, a y direction and a z direction, respectively, wherein the x direction, the y direction and the z direction may be two straight line directions perpendicular to each other, and an xyz coordinate system may be established according to the x direction, the y direction and the z direction.
The acceleration sensor is used for acquiring the acceleration in the x direction, the acceleration in the y direction and the acceleration in the z direction, and the vibration amplitude in the three directions can be calculated according to the acceleration, so that the amplitude of the water holding barrel is determined, the dehydration rotating speed of the dehydration barrel is regulated according to the amplitude change of the water holding barrel, the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water is avoided, the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and the energy is effectively saved.

It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.
Control methods of a washing machine, and a readable storage medium according to some embodiments of the present application are described below with reference to fig. 1 to 7.
Example 1
In some embodiments of the present application, fig. 1 shows one of flowcharts of a control method of a washing machine including a tub and a dehydrating tub according to an embodiment of the present application, the control method of the washing machine including the steps of:
102, acquiring a dehydration rotating speed of a dehydration barrel, and acquiring an amplitude of the water holding barrel under the condition that the dehydration rotating speed is greater than or equal to a first rotating speed threshold value;
And 104, when the amplitude is larger than the amplitude threshold value, reducing the dehydration rotating speed until the dehydration is finished.
In the embodiment of the invention, the rotation speed of the dewatering barrel, namely the dewatering rotation speed, is firstly obtained in the dewatering process of the washing machine. If the dehydration rotation speed is greater than the first rotation speed threshold value, further acquiring the amplitude of the water containing bucket, and adjusting the dehydration rotation speed of the dehydration bucket according to the amplitude of the water containing bucket.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the spin speed increases to a certain threshold, specifically a first spin speed threshold, it means that the spin state of the washing machine has reached the maximum spin speed, and the amplitude of the tub is obtained at this time.
Wherein, in the dehydration process, water adsorbed by clothes in the dehydration barrel is 'thrown' out and finally falls into the water containing barrel, so as the water in the dehydration barrel enters the water containing barrel, the quality of the dehydration barrel is reduced, the quality of the water containing barrel is increased, the quality change can lead to unbalanced movement of the water containing barrel, and the phenomenon of amplitude change is caused, thereby noise is formed. While a higher spin rate represents a spin process closer to the tail while being more prone to noise.
Therefore, the method can judge whether the water holding barrel generates extra noise in the dewatering ending stage according to the amplitude of the water holding barrel, dynamically adjust the dewatering rotating speed of the dewatering barrel according to the real-time amplitude of the water holding barrel, and avoid the noise of the water holding barrel by adjusting the dewatering rotating speed when the amplitude is large, thereby being beneficial to realizing mute dewatering.
Example two
In some embodiments of the present invention, the control method of a washing machine further includes: and under the condition that the dehydration rotating speed is larger than or equal to the second rotating speed threshold value and smaller than the first rotating speed threshold value, determining the variation of the amplitude, and adjusting the dehydration rotating speed according to the variation.
In the embodiment of the invention, the rotation speed of the dewatering barrel, namely the dewatering rotation speed, is firstly obtained in the dewatering process of the washing machine. If the dehydration rotation speed is greater than the second rotation speed threshold value but less than the first rotation speed threshold value, further acquiring the amplitude of the water bucket, and adjusting the dehydration rotation speed of the dehydration bucket according to the variation of the amplitude of the water bucket.
Specifically, after the washing machine enters the dehydration stage, the dehydration rotation speed gradually increases as the dehydration progresses. When the dehydration rotation speed is increased to the second rotation speed threshold value, it represents that the dehydration process has been started for a while, and the variation of the amplitude of the tub is acquired.
In the dehydration process, water adsorbed by clothes in the dehydration barrel is thrown out and finally falls into the water containing barrel, so that the quality of the dehydration barrel is reduced as the water of the dehydration barrel enters the water containing barrel, the quality of the water containing barrel is increased, and the quality is changed, so that movement is unbalanced, and the amplitude of the water containing barrel is unbalanced, namely, the amplitude of the water containing barrel is changed.
Therefore, the change in the mass of the tub can be observed based on the change in the amplitude of the tub. Specifically, when the amplitude of the tub is in a trend of variation, it is indicated that the quality of both the tub and the dehydrating tub is changed, and at this time, the water of the laundry in the dehydrating tub is not "spin-dried", so that the progress of the dehydration can be maintained. When the amplitude of the water holding barrel tends to be gentle, the quality of the water holding barrel and the quality of the dewatering barrel are approximately unchanged, namely, under the current dewatering rotating speed, no water enters the water holding barrel from the dewatering barrel, so that the gear of the dewatering rotating speed can be increased, the next dewatering stage can be advanced, the phenomenon that the washing machine wastes time in the current dewatering stage, namely, the current dewatering rotating speed is avoided, and the purpose of saving the dewatering time is achieved.
By applying the embodiment of the application, the dehydration rotating speed of the dehydration barrel is regulated according to the amplitude change of the water containing barrel, so that the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water 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.
Example III
In some embodiments of the present application, fig. 2 shows a second flowchart of a control method of a washing machine according to an embodiment of the present application, specifically, a process of determining a variation amount of amplitude, specifically, comprising the steps of:
step 202, obtaining a first amplitude at a first moment;
step 204, obtaining a second amplitude at a second time interval of a preset duration from the first time interval;
in step 206, the variation is determined according to the difference between the second amplitude and the first amplitude.
In the embodiment of the present application, the amplitude variation amount of the tub may be determined according to a difference in amplitude of the tub at the first time and at the second time.
Specifically, when the dehydration rotation speed is greater than the second rotation speed threshold, the first amplitude is acquired at a first moment, wherein the "first moment" can be any moment in the dehydration process or any moment, but is not a fixed time point, and the specific time of the first moment is not limited by the present application.
After the first amplitude is obtained, the second amplitude is obtained at a second moment after a delay preset time, wherein the second moment can be any moment in the dehydration process or any moment, but is not a fixed time point, and the specific time of the second moment is not limited by the application.
According to the difference value of the first amplitude and the second amplitude, the variation of the amplitude of the water holding barrel in the preset time period is calculated, the dehydration rotating speed of the dehydration barrel is regulated according to the variation, and the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water is avoided, so that the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and energy sources can be effectively saved.

Specifically, when the variation of the amplitude meets the interval of a certain variation threshold, the quality area of the current water holding barrel is considered to be stable, the dewatering effect of the current dewatering stage is judged to be met, and the dewatering rotation speed is increased at the moment, so that the washing machine enters the next dewatering stage in advance, the dewatering rotation speed of the washing machine is increased, and the dewatering time is effectively saved.
Example five
In some embodiments of the present invention, fig. 3 illustrates a third flowchart of a control method of a washing machine according to an embodiment of the present invention, specifically, the rotation speed threshold includes a first threshold, a second threshold, and a third threshold, and according to a comparison result of the variation amount and a preset rotation speed threshold, controlling the dehydration tub to increase the dehydration rotation speed may include the steps of:
step 302, adjusting the dehydration rotating speed to be a first rotating speed under the condition that the variation is smaller than a first threshold value and larger than or equal to a second threshold value;
step 304, adjusting the dehydration rotating speed to a second rotating speed under the condition that the variation is smaller than a second threshold value and larger than or equal to a third threshold value;
And 306, adjusting the dehydration rotating speed to be a third rotating speed when the variation is smaller than the third threshold value and larger than or equal to the fourth threshold value.
The first rotation speed threshold value is equal to a third rotation speed, the third rotation speed is larger than the second rotation speed, and the second rotation speed is larger than the first rotation speed.
In the embodiment of the invention, the rotation speeds of the first rotation speed, the second rotation speed and the third rotation speed are in an increasing trend, and when the variation is between the second threshold value and the first threshold value, the dehydration work is described as meeting 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 water holding barrel is continuously obtained.
If the variation is further between the third threshold value and the second threshold value, the dehydration rotating speed of the dehydration barrel is continuously increased, specifically to the second rotating speed, the rotating speed gear lifting of the dehydration barrel is controlled again, and the variation of the amplitude of the water containing barrel is continuously obtained.
When the variation is smaller than the third threshold value but larger than the fourth threshold value, the dehydration rotating speed of the dehydration barrel is increased to the third rotating speed of the highest gear, and the dehydration barrel rotates at a high speed at the moment so as to ensure the final dehydration 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 variation of the amplitude of the water containing bucket, and the next dehydration stage is advanced after the effect is achieved, so that the total dehydration time is reduced, and the time and energy conservation are realized.
Example six
In some embodiments of the invention, the washing machine is controlled to end the spin-drying phase if the amount of change is less than a fourth threshold.
In the embodiment of the invention, if the variation of the amplitude of the water containing barrel is smaller than the fourth threshold value, the quality of the water containing barrel is basically not changed, at the moment, the dewatering effect can be judged to be achieved, and the washing machine is controlled to finish the dewatering stage, so that on one hand, the dewatering time can be reduced, the time saving is realized, and on the other hand, the condition that the dewatering barrel of the washing machine continuously works under the condition that the clothes in the dewatering barrel are 'spin-dried' is avoided, and the energy sources can be saved and the mechanical loss can be reduced.
Example seven
In some embodiments of the invention, the washing machine is controlled to end the spin phase in the event that the spin speed is greater than a second speed threshold and the amplitude is greater than an amplitude threshold.
In the embodiment of the invention, if the dehydration rotation speed of the dehydration barrel is higher than the second rotation speed threshold value, and the amplitude of the water containing barrel is obtained to be larger than the preset amplitude threshold value, the dehydration stage is ended. Specifically, at the beginning of the dehydration stage, the dehydration tub is operated at a lower rotational speed, and the dehydration rotational speed of the dehydration tub is gradually increased, in which process water in laundry is gradually thrown out and enters the tub, and the tub is rapidly changed in mass at this time, so that the amplitude of the tub is large.
However, as the dehydration speed increases gradually, for example, when the dehydration speed increases above the second speed threshold, it means that the dehydration process has entered a steady state in which a certain mass of water has been accumulated in the tub, and the total mass increases, so that the mass increase ratio decreases, and the amplitude of the tub should be less than the amplitude threshold. If the amplitude of the water bucket is still higher than the amplitude threshold after the dehydration rotating speed is increased to be higher than the second rotating speed threshold, the serious eccentricity of the water bucket is indicated, so that the washing machine is controlled to finish the dehydration process and the dehydration stage, thereby ensuring the use safety of the washing machine, preventing the washing machine from being damaged, avoiding the noise increase caused by the large eccentricity, and being beneficial to realizing silence.
It can be appreciated that the washing machine may start the dehydration again according to the program setting after the end of the dehydration phase, or restart the dehydration after at least one rinsing phase. In some embodiments, if the eccentricity of the tub occurs continuously, a corresponding alarm prompt may be issued while recording a fault log for reference by a serviceman.
Example eight
In some embodiments of the present invention, fig. 4 shows a fourth flowchart of a control method of a washing machine according to an embodiment of the present invention, specifically, the control method of a washing machine further includes the steps of:
Step 402, obtaining a dehydration rotating speed;
and step 404, when the dehydration rotating speed is greater than or equal to the third rotating speed threshold value and less than the second rotating speed threshold value, supplementing water to the water bucket according to the amplitude.
In the embodiment of the invention, after the dehydration rotation speed is greater than the third rotation speed threshold, namely, the dehydration state is entered and the first dehydration gear is reached, if the dehydration rotation speed does not reach the second rotation speed threshold, the water holding barrel can be supplemented according to the amplitude of the water holding barrel.
Specifically, the vibration of the tub is mainly due to the mass change caused when water enters the tub, so the lighter the tub, the more remarkable the mass change, and the larger the resulting vibration amplitude. When the dehydration rotation speed does not reach the second rotation speed threshold value at the beginning of the dehydration stage, because the dehydration stage has short beginning time, enough water is not accumulated in the water bucket, so the water bucket has lighter weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, the water bucket is subjected to water supplementing operation according to the amplitude of the water bucket, so that the mass of the water bucket can be effectively increased in the initial stage of dehydration, the amplitude of the water bucket is reduced, excessive noise generated by vibration of the water bucket is avoided, and mute dehydration is facilitated.
Example nine
In some embodiments of the present invention, fig. 5 shows a fifth flowchart of a control method of a washing machine according to an embodiment of the present invention, specifically, replenishing water to a tub according to an amplitude, comprising the steps of:
step 502, under the condition that the amplitude is larger than the amplitude threshold value, water is supplemented to the water bucket;
and 504, stopping water supplementing to the water bucket and increasing the dehydration rotating speed until the dehydration rotating speed is greater than or equal to a second rotating speed threshold value under the condition that the amplitude is smaller than the amplitude threshold value.
In the embodiment of the invention, since the vibration of the tub is mainly from the mass change caused when water enters the tub, the lighter the tub, the more remarkable the mass change, and the larger the resulting vibration amplitude. When the dehydration rotation speed does not reach the second rotation speed threshold value at the beginning of the dehydration stage, because the dehydration stage has short beginning time, enough water is not accumulated in the water bucket, so the water bucket has lighter weight, and the condition of overlarge amplitude is easy to occur at the moment.
Therefore, when the amplitude of the water holding barrel exceeds the amplitude threshold value, clean water is injected into the water holding barrel according to a certain flow through a water supplementing algorithm, so that the quality of the water holding barrel is improved, the vibration of the water holding barrel caused by the change of the quality is reduced, the excessive noise generated by the vibration of the water holding barrel is avoided, and the mute dehydration is facilitated.
When the amplitude of the water holding bucket is smaller than the amplitude threshold value, the water holding bucket is considered to be stable, excessive noise is not generated, water replenishing is stopped at the moment, the dehydration rotating speed is increased, dehydration enters the next dehydration stage, on one hand, the dehydration time is reduced, and on the other hand, energy sources can be effectively saved.

It can be understood that the acceleration sensor may be other types of acceleration sensors, the number of the acceleration sensors may be one or more, and the setting positions may be at the bottom, the side wall, etc. of the tub, which is not limited in the embodiment of the present application.

The acceleration sensor is used for acquiring the acceleration in the x direction, the acceleration in the y direction and the acceleration in the z direction, and the vibration amplitude in the three directions can be calculated according to the acceleration, so that the amplitude of the water holding barrel is determined, the dehydration rotating speed of the dehydration barrel is regulated according to the amplitude change of the water holding barrel, the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water is avoided, the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and the energy is effectively saved.
Example eleven
In some embodiments of the present invention, the dehydration process of the washing machine includes 6 dehydration stages, each corresponding to one dehydration speed, the dehydration speeds of the 6 dehydration stages being increased step by step. Specifically, for example, the dehydration rotational speed includes the following phases:
180rpm phase, 300rpm phase, 400rpm phase, 500rpm phase, 600rpm phase and 700rpm phase.
Fig. 6 illustrates a sixth flowchart of a control method of a washing machine according to an embodiment of the present invention, and in particular, a dehydration process includes:
Step 602, entering a 180rpm stage;
step 604, judging whether the amplitude of the water bucket exceeds an amplitude threshold; if yes, go to step 610, otherwise go to step 606;
step 606, entering a 300rpm stage;
step 608, judging whether the amplitude of the water bucket exceeds an amplitude threshold; if yes, go to step 610, otherwise go to step 612;
step 610, make up water, enter the next stage;
step 612, entering a 400rpm stage;
step 614, determining whether the amplitude variation is smaller than a first threshold, if yes, proceeding to step 616, otherwise returning to step 612;
step 616, go to 500rpm stage;
step 618, judging whether the amplitude variation is smaller than the second threshold, if yes, proceeding to step 620, otherwise returning to step 616;
step 620, entering 600rpm stage;
step 622, determining whether the amplitude variation is smaller than a third threshold, if yes, proceeding to step 624, otherwise returning to step 620;
step 624, entering a 700rpm stage;
step 626, determining whether the amplitude variation is smaller than the fourth threshold, if yes, proceeding to step 628, otherwise returning to step 624;
step 628, determining whether the amplitude exceeds an amplitude threshold; if yes, go to step 630, otherwise return to step 624;
step 630, downshift to 650rpm stage;
Step 632, determining if the amplitude exceeds an amplitude threshold; if yes, go to step 634, otherwise repeat step 632;
step 634, downshift to 600rpm stage.
Wherein, simultaneously with step 614, step 618, step 622 and step 626, it is synchronously determined whether the amplitude exceeds the amplitude threshold, and if the amplitude exceeds the threshold, it is directly ended.
In the embodiment of the invention, the rotation speed of the dewatering barrel, namely the dewatering rotation speed, is firstly obtained in the dewatering process of the washing machine. If the dehydration rotation speed is greater than the first rotation speed threshold value, further acquiring the amplitude of the water bucket, and adjusting the dehydration rotation speed of the dehydration bucket according to the variation of the amplitude of the water bucket.
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, specifically a first rotation speed threshold, it represents that the dehydration process has started for a period of time, and the variation of the amplitude of the water tub is acquired.
In the dehydration process, water adsorbed by clothes in the dehydration barrel is thrown out and finally falls into the water containing barrel, so that the quality of the dehydration barrel is reduced as the water of the dehydration barrel enters the water containing barrel, the quality of the water containing barrel is increased, and the quality is changed, so that movement is unbalanced, and the amplitude of the water containing barrel is unbalanced, namely, the amplitude of the water containing barrel is changed.
Therefore, the change in the mass of the tub can be observed based on the change in the amplitude of the tub. Specifically, when the amplitude of the tub is in a trend of variation, it is indicated that the quality of both the tub and the dehydrating tub is changed, and at this time, the water of the laundry in the dehydrating tub is not "spin-dried", so that the progress of the dehydration can be maintained. When the amplitude of the water holding barrel tends to be gentle, the quality of the water holding barrel and the quality of the dewatering barrel are approximately unchanged, namely, under the current dewatering rotating speed, no water enters the water holding barrel from the dewatering barrel, so that the gear of the dewatering rotating speed can be increased, the next dewatering stage can be advanced, the phenomenon that the washing machine wastes time in the current dewatering stage, namely, the current dewatering rotating speed is avoided, and the purpose of saving the dewatering time is achieved.
The rotational speeds of 400rpm, 500rpm, 600rpm and 700rpm are in an increasing trend, and under the condition that the variation is between the second threshold value and the first threshold value, the dehydration work is satisfied in the current stage, the dehydration rotational speed of the current dehydration barrel is increased to 500rpm, namely, the dehydration rotational speed of the dehydration barrel is controlled to be increased by one gear, and the variation of the amplitude of the water containing barrel is continuously obtained.
If the variation is further between the third threshold value and the second threshold value, the dehydration rotating speed of the dehydration barrel is continuously increased, specifically to 600rpm, the rotating speed gear lifting of the dehydration barrel is controlled again, and the variation of the amplitude of the water containing barrel is continuously obtained.
When the variation is smaller than the third threshold but larger than the fourth threshold, the dehydration rotating speed of the dehydration barrel is increased to 700rpm of the highest gear, and the dehydration barrel rotates at a high speed at the moment so as to ensure the final dehydration 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 variation of the amplitude of the water containing bucket, and the next dehydration stage is advanced after the effect is achieved, so that the total dehydration time is reduced, and the time and energy conservation are realized.
By applying the embodiment provided by the invention, after the dehydration rotating speed reaches a certain first rotating speed threshold, the dehydration rotating speed of the dehydration barrel is regulated according to the amplitude change of the water containing barrel, so that the time waste caused by the fact that the washing machine still maintains the current dehydration rotating speed according to a fixed program when the current dehydration rotating speed cannot throw more water is avoided, the dehydration time is effectively shortened, the washing and dehydration speeds of the washing machine are improved, and the energy is effectively saved.
