Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a dehydration control mode, wherein whether to carry out eccentricity detection on the washing machine is determined according to the rotating speed during pause recovery, so that the restart time after pause is greatly shortened.

The washing machine is an essential tool in life of people, great convenience is brought to life of people, starting and pausing are inevitably caused by pressing a start-stop key in the washing process, two situations generally occur when the washing machine on the market is restarted after pausing at present, firstly, the operation is continued to leave a flow, eccentric detection is not carried out again, but the washing machine is easy to generate deviation when the rotating speed is reduced below a certain rotating speed, so that the operation greatly improves the possibility of barrel collision; secondly, the eccentricity detection is carried out again, and the dehydration process is operated again, so that the dehydration time is greatly increased. For example, if the washing machine is restarted when the dehydration is suspended, and the speed is not reduced to 0 at the moment, the restarting is very time-consuming and resource-wasting due to the adoption of the method of re-eccentricity detection and the need of stopping; however, if the laundry is decelerated to 80 f or less, the laundry may be deviated, and at this time, if the eccentricity detection is not performed, the tub collision may be easily caused. Therefore, the scheme provides a new dehydration control mode, and the control is carried out according to the rotating speed of the washing machine during the pause and the recovery.

The present embodiment proposes a dehydration control method of a washing machine, as shown in a control flowchart of fig. 1, the control method including:

when the washing machine is restarted after being suspended in the dehydration process, acquiring the current rotating speed n of the washing machine;

and judging whether the washing machine carries out eccentricity detection again or not and whether the dehydration process is continued or not according to the current rotating speed n of the washing machine.

By adopting the method, in the dehydration process, after the washing machine is paused and restarted, whether the clothes in the washing machine have the possibility of deviation or not is judged according to the existing rotating speed of the washing machine, whether the eccentric detection is needed again or not is judged, the restarting time after pausing is greatly shortened, and the user experience is also improved.

The washing machine is started after being suspended, is not controlled by single logic and is controlled by different conditions. As shown in the control logic diagram of figure 2,

one of the cases is that when the rotation speed n after the washing machine is restarted satisfies: n is more than or equal to a first set rotating speed n1, the washing machine is controlled to slow down to the next rotating speed, the speed is increased again after the first set time is maintained, and the dehydration process before pause is resumed.

The washing machine is started after being suspended in the dewatering process, at the moment, when a user finds that the barrel is just decelerated to a middle-high speed (the rotating speed is greater than or equal to n1, and the rotating speed of n1 is 300 revolutions optionally), the user can press the starting key again due to misoperation or other reasons, the rotating speed in the barrel is high enough, the clothes are not displaced, if the user waits for complete stop and then carries out eccentric detection again, the dewatering process is carried out, the user time is greatly wasted, and electricity is wasted. Therefore, at this time, an operation is adopted, namely, the rotating speed of the washing machine is reduced to the first set time of the next gear rotating speed, the first set time is optionally 10s (the waiting time in the first set time is the time reserved for the stable operation of the motors and can be modified according to the performance of each motor), the rotating speed is increased again to the rotating speed before suspension, and the dewatering process is continued to operate. The washing machine is started after being suspended, if the rotating speed in the barrel is still more than or equal to n1 at the moment, the barrel is not stopped, the rotating speed is maintained at the next gear of rotating speed for a certain time, if 10s later, the rotating speed is increased again, the original dehydration process is recovered, and the time is saved; the rotating speed is firstly reduced to the next gear of rotating speed, so that the motor can be better stabilized, and the direct speed increase is possible to cause the fault due to the fact that the motor cannot react in time.

The second case is that when the rotation speed n after the washing machine is restarted satisfies: and n is more than 0 and less than the first set rotating speed n1, the eccentricity detection is carried out again, and whether the washing machine is controlled to continue to operate or not is determined according to the eccentricity detection result and the rotating speed before pause.

The washing machine is started after being suspended in the dehydration process, the barrel may not be completely stopped (the rotating speed is more than 0) at the moment, but the rotating speed is less than n1 (namely the rotating speed n is more than 0 and less than or equal to n1), the dehydration process is directly continued to be operated after the next rotating speed is maintained at the moment, clothes are likely to deviate, therefore, the eccentricity detection is carried out again, then the classification control is carried out according to the eccentricity result and the rotating speed before suspension, whether the operation is continued or not is judged, and the eccentricity detection is needed to be carried out again; since the laundry may be shifted during the eccentricity detection of the laundry, and the maximum rotational speed after the eccentricity detection may be different from that before the pause, the determination needs to be performed in combination with the rotational speed before the pause.

Further optionally, the determining whether to control the washing machine to continue to operate according to the eccentricity detection result includes

Acquiring the rotating speed n2 of the washing machine before pause and the highest rotating speed n3 of the washing machine after eccentricity detection;

whether the washing machine is controlled to continue to operate is jointly determined by judging whether the spinning rotating speed n2 before pause meets the spinning completion condition and comparing the rotating speed n2 before pause with the highest rotating speed n3 after eccentricity detection.

The current dehydration rotating speed n2 before pause is more than or equal to a second set rotating speed n4, and the dehydration is continued for a second set time, which is regarded as meeting the dehydration finishing condition, wherein the second set rotating speed n4 is more than or equal to the highest rotating speed before pause.

When the dehydration rotation speed n2 before pause meets the dehydration completion condition, if n2 is not more than n3, the washing machine is controlled to recover to the dehydration rotation speed before pause, and the rest dehydration process is continuously operated. If n2 is more than n3, the dewatering process is stopped, and the washing machine is finished.

Specifically, if the dewatering rotating speed before pause meets the dewatering finishing condition (namely the dewatering rotating speed n2 before pause is more than or equal to a second set rotating speed n4 and lasts for a second set time, and the second set rotating speed n4 is less than or equal to the highest rotating speed before pause, optionally, the dewatering finishing condition is that the dewatering rotating speed n2 before pause is more than or equal to 1000 and the second set time is more than 10s), the method is divided into two conditions that firstly, the highest rotating speed n3 after re-eccentricity detection is the same as or higher than the rotating speed n2 before pause, the rotating speed of the previous dewatering process is recovered, namely the rotating speed n2 before pause is recovered, and as the dewatering rotating speed before pause meets the dewatering finishing condition, the residual dewatering process is continuously run for deep dewatering in a shorter time, and the dewatering effect is improved; secondly, if the highest rotating speed n3 after re-eccentricity detection is lower than the rotating speed n2 before pause, the dehydration process can be directly stopped, and the operation is finished. Because the rotating speed before pause reaches the dewatering finishing condition, if deep dewatering needs to be carried out, eccentricity detection is carried out again, and the dewatering is directly stopped under the condition that the dewatering condition is met in consideration of the power consumption problem and the overlong eccentricity detection time.

When the dehydration rotation speed n2 before pause does not meet the dehydration completion condition, if n2 is not more than n3, the washing machine is controlled to recover the dehydration rotation speed before pause, and the residual dehydration process is continuously operated. If n2 is more than n3, the eccentricity detection is carried out again until the highest rotating speed n3 after the eccentricity detection is more than or equal to the rotating speed n2 before the pause, the washing machine is controlled to recover the dehydrating rotating speed before the pause, and the residual dehydrating process is continuously operated

If the dewatering rotating speed before pause does not meet the dewatering finishing condition (namely the dewatering rotating speed n2 before pause is less than the second set rotating speed n4, the two conditions are divided into two conditions, namely, the highest rotating speed n3 after re-eccentricity detection is the same as or higher than the second set rotating speed n4, which indicates that the rotating speed after re-eccentricity detection can reach the rotating speed n4 of the dewatering finishing condition, the rotating speed n2 of the previous dewatering process is recovered, the dewatering process is continuously operated, and secondly, the highest rotating speed n3 after re-eccentricity detection is lower than the second set rotating speed n4, the eccentricity detection is performed again, until the highest rotating speed n3 is higher than or equal to the second set rotating speed n4, which indicates that the rotating speed after re-eccentricity detection can reach the rotating speed n4 of the dewatering finishing condition, the rotating speed of the previous dewatering process is recovered, and the dewatering process is continuously operated.

For example:

firstly, the highest rotating speed is 1300 before pause, the rotating speed is 1200 at the moment, the pause is pressed, the dewatering completion condition is determined to be met, and after the restart, if the highest rotating speed is 1000 after the eccentricity detection, the dewatering process is ended;

secondly, the highest rotating speed is 1300 before pause, the rotating speed is 1200 at the moment, the pause is pressed, the condition that the dehydration is finished is determined to be met, after the restart, if the highest rotating speed is 1300 after the eccentricity detection, the dehydration rotating speed before the pause is recovered, and the dehydration process is continuously finished;

thirdly, the highest rotating speed is 1300 before pause, the rotating speed is 800 at the moment, the pause is pressed, the condition that the dewatering finishing is not met is determined, after the restart, if the highest rotating speed is 1300 after the eccentricity detection, the dewatering rotating speed before the pause is recovered, and the dewatering process is continuously operated;

and fourthly, the highest rotating speed is 1300 before pause, the rotating speed is 800 at the moment, the pause is pressed, the condition that the dewatering completion is not met is determined, after the restart, if the highest rotating speed is 600 after the eccentricity detection, the eccentricity detection is carried out again until the highest rotating speed is more than or equal to 800, and the previous dewatering process is continued.

In the third case, when n is 0, the eccentricity detection is performed again, and the dehydration process is re-run. If the washing machine is suspended during the dehydration process and the rotation speed is reduced to 0, the eccentricity detection is performed again and the whole dehydration process is operated again in consideration of the fact that the user may add or subtract clothes in the washing machine.

The present embodiment also proposes a washing machine that employs the dehydration control method of any one of the above.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
