s2, judging whether the washing barrel is eccentric or not, if so, entering the next step;
and S3, controlling the washing barrel to stop at a position deviating from the dehydration starting position by a preset angle, and then continuing the dehydration.
Further, in the step S3, the dehydration is continued, and the process returns to the step S2.
Further, the step S2 includes detecting the eccentricity of the washing tub and counting the number of the eccentricity; and comparing the eccentric times with a preset threshold value, and executing subsequent steps according to a comparison result.
Further, if it is judged that the number of decentering times is less than the preset threshold value, the process proceeds to step S3.

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, and it will be understood by those skilled in the art that the following embodiments are only for explaining the technical principles of the present invention and are not intended to limit the scope of the present invention.
For example, although the present application describes the steps of the method of the invention in a particular order, these orders are not limiting, and one skilled in the art can perform the steps in a different order without departing from the underlying principles of the invention.
Next, the control method will be further described.
As an embodiment of the present invention, the present embodiment provides an eccentricity correction method for correcting eccentricity of a washing machine, wherein a flowchart of the eccentricity correction method is shown in fig. 1, and the method comprises the following steps:
s1, determining the dehydration starting position of the washing barrel and starting dehydration;
s2, judging whether the washing barrel is eccentric or not, if so, entering the next step;
and S3, controlling the washing barrel to stop at a position deviating from the dehydration starting position by a preset angle, and then continuing the dehydration.
Specifically, a dehydration start position of the washing tub is determined before dehydration is started, and during the dehydration, the balance detection device detects the operation balance of the washing tub, and if the washing tub is always in a balanced state, dehydration is performed according to a set dehydration program.
If the balance detecting means detects the eccentricity of the washing tub in step S2, the process proceeds to step S3, specifically: and controlling the washing barrel to stop rotating, turning the washing barrel to a dehydration starting position, turning the washing barrel to a position deviating from the dehydration starting position and presetting an angle, and then continuing to dehydrate.
After the steps are finished, if the eccentricity still exists, entering an alarm program or a deviation rectifying program, prompting a user that the washing machine generates the eccentricity through the machine or the mobile terminal and prompting the user to process; or prompting the user to correct the eccentricity according to a set program.
As another embodiment of the present invention, the present embodiment provides an eccentricity correction method for performing eccentricity correction on a pulsator washing machine.
In this embodiment, the sensor determines the dehydration start position of the washing tub before the dehydration starts, and the balance detection device detects the operation balance of the washing tub during the dehydration, and if the washing tub is always in a balanced state, the dehydration is performed according to the set dehydration program.
If the balance detecting means detects that the washing tub is eccentric, the process proceeds to step S3, and the controller controls the washing tub to stop rotating, rotates the washing tub to a dehydration start position, rotates the washing tub to a position deviated from the dehydration start position by a preset angle, continues to dehydrate, and returns to step S2.
Based on the above technical solution, further, in step S2, the washing machine detects the eccentricity of the washing tub, and the counter counts the eccentricity times; and comparing the eccentric times with a preset threshold value, and executing subsequent steps according to a comparison result.
And when the eccentric times are smaller than the preset threshold value, the step S3 is carried out, the controller controls the washing barrel to stop rotating, the washing barrel is rotated to the dehydration starting position at a low speed, then the washing barrel is rotated to the position deviating from the dehydration starting position by the preset angle, and then the dehydration is continued.
Or, firstly controlling the washing barrel to stop at the dehydration starting position; and then controlling the washing barrel to rotate to a position deviating from the preset angle of the dehydration starting position.
Further, returning to step S2 after step S3 is completed, if the balance detecting means does not detect the eccentricity of the washing tub, the dehydrating step is normally performed, and the counter is reset;
if the eccentricity of the washing barrel is still detected, the counter is increased by one, the controller compares the eccentricity times with a preset threshold value, and the subsequent steps are determined according to the comparison result.
If the count of the counter is still less than the preset threshold, the flow proceeds to step S3 again, and returns to step S2 after step S3 is completed.
In the above scheme, the preset angle in step S3 increases at the same speed as the number of eccentricities increases, and the preset angle is smaller than 360 °.
Preferably, the degree of increase of each preset angle is the same and is 90 degrees.
In the above scheme, the preset threshold is an integer part of a result obtained by dividing 360 ° by a preset angle increase degree.
As an alternative to the above, in step S3, the controller controls the washing tub to stop rotating, rotates the washing tub to the dehydration start position, rotates the washing tub to a position deviated from the dehydration start position by a preset angle, positions the current position as a new dehydration start position, and then continues to dehydrate.
Or, the washing barrel is controlled to stop at the dehydration starting position, then the washing barrel is controlled to rotate to a position deviating from the dehydration starting position by a preset angle, the current position is positioned to be used as a new dehydration starting position, and then dehydration is continued.
In the above alternative scheme, by positioning the new dehydration starting position, the problem that the washing tub cannot be accurately stopped at the position deviating from the preset angle of the dehydration starting position due to the overlarge preset angle is avoided, and the accuracy of eccentric correction is improved.
Preferably, the angle of rotation is 90 ° per one time on the basis of the dehydration start position.
Furthermore, if the eccentric times recorded by the counter are equal to the preset threshold value, the counter is reset, and the controller controls the washing machine to execute an alarm program or a deviation correcting program;
the deviation rectifying program specifically comprises the following steps: and injecting a certain amount of water into the washing barrel, controlling the washing barrel to rotate positively and negatively to uniformly disperse the washings, and then continuously dehydrating.
The alarm program is as follows: the washing machine gives an alarm to the user through the washing machine or the mobile terminal of the user to prompt the user to process the eccentricity.
In the above scheme, the preset threshold is an integer part of a result of dividing 360 ° by a preset angle.
Further, the preset angle may also be one or a group of angles set by the user.
In this embodiment, as an alternative to the above, the time consumed for the eccentricity correction may be measured in step S2, and the time consumed for the eccentricity correction may be compared with a preset time threshold range, so as to determine the subsequent step according to the comparison result.
If the time consumed for the eccentricity correction falls within the preset time threshold range, the process proceeds to step S3.
After the step S3 is finished, returning to the step S2, if the eccentricity is not detected, clearing the timer, and continuing the dehydration step; if the eccentricity is still detected, the time consumed for the eccentricity correction is again compared with the preset time threshold range, and if the time consumed for the eccentricity correction falls within the preset time threshold range, the process proceeds to step S3 again.
If the time consumed by the eccentricity correction exceeds the preset time threshold range, the timer is reset, and an alarm program or a deviation correction program is executed.
According to the scheme, the washing efficiency is prevented from being reduced and the user experience is prevented from being reduced due to the fact that the eccentric correction time is too long by limiting the eccentric correction time.
