Examples 1,
Specifically, the present application provides a washing machine control method, as shown in fig. 4, including:
s11, adjusting the clothes load distribution after starting the washing machine and starting the dehydration.
The purpose of adjusting the clothes load distribution is to make the clothes load uniform as much as possible, so that the eccentricity of the clothes load is not too large when the washing machine runs at a high speed, and the outer barrel is prevented from colliding with the box body, shifting and the like.
The number of adjustments may also be limited, and if the uniform distribution of the laundry load is not achieved even after the number of adjustments exceeds a threshold, the dehydration is directly stopped.
And S12, detecting the eccentricity of the clothes load.
The eccentricity of the laundry load may be caused by the uneven distribution of the laundry.
And S13, if the eccentricity is less than or equal to the eccentricity threshold, controlling the washing machine to operate at a first rotating speed or less, and detecting the displacement of the outer tub in the three-dimensional direction.
For example, the first rotational speed may be 400 Revolutions Per Minute (RPM). The three-dimensional directions include X/Y/Z directions, wherein the X direction refers to a direction perpendicular to the front surface of the washing machine, the Y direction refers to a horizontal direction parallel to the front surface of the washing machine, and the Z direction refers to a vertical direction parallel to the front surface of the washing machine.
And S14, if the displacements of the outer barrel in the three-dimensional directions are all smaller than or equal to the corresponding displacement threshold, controlling the washing machine to operate at a second rotating speed.
Wherein the second rotation speed is greater than the first rotation speed. The displacement in the X direction is smaller than the displacement threshold in the X direction, the displacement in the Y direction is smaller than the displacement threshold in the Y direction, and the displacement in the Z direction is smaller than the displacement threshold in the Z direction. For example, the second rotational speed may be 600 RPM.
When the second rotating speed is less than or equal to the first rotating speed, the low-speed operation process can be considered, and the displacement is involved in the logic judgment process.
And S15, detecting the acceleration of the outer barrel in at least one direction in the three-dimensional directions.
Three, any two or any one of the three-dimensional directions may be detected, and at least one of the three-dimensional directions may be a vertical direction (i.e., a Z direction), i.e., an acceleration in the vertical direction is mainly detected.
It should be noted that the detection process is continuously performed in the subsequent steps, and therefore the detected acceleration value also changes from moment to moment.
And S16, controlling the rotating speed of the washing machine in the rotating speed set according to the acceleration, wherein the rotating speed in the rotating speed set is greater than the second rotating speed.
When the rotation speed is higher than the second rotation speed, the high-speed operation process can be considered, and the acceleration is involved in the logic judgment process.
Specifically, referring to fig. 5, step S16 may include:
and S1601, if the acceleration a is smaller than or equal to the first threshold A1, controlling the washing machine to operate at the third rotating speed.
And S1602, if the acceleration a is greater than the first threshold A1 and less than or equal to the second threshold A2, controlling the washing machine to operate at a fourth rotating speed.
S1603, if the acceleration a is greater than the second threshold A2 and less than or equal to the third threshold A3, controlling the washing machine to operate at a fifth rotating speed.
And S1604, if the acceleration a is greater than the third threshold A3 and less than or equal to the fourth threshold A4, controlling the washing machine to operate at a sixth rotating speed.
And S1605, if the acceleration a is larger than the fourth threshold A4, stopping the dehydration.
Wherein the third speed > the fourth speed > the fifth speed > the sixth speed > the second speed. For example, the third speed may be 1400RPM, the fourth speed may be 1200RPM, the fifth speed may be 1000RPM, and the sixth speed may be 800 RPM.
Specifically, referring to fig. 6, step S16 may further include:
and S1606, when the washing machine operates at the fourth rotating speed, if the acceleration a is less than or equal to a fifth threshold A5, controlling the washing machine to operate at the third rotating speed.
Otherwise, the washing machine is kept running at the fourth rotating speed until the dehydration program is finished.
And S1607, when the washing machine operates at the fifth rotating speed, if the acceleration a is less than or equal to the sixth threshold A6, controlling the washing machine to operate at the third rotating speed.
And S1608, if the acceleration a is greater than the sixth threshold A6 and less than or equal to the seventh threshold A7, controlling the washing machine to operate at the fourth rotating speed.
And S1609, if the acceleration a is larger than a seventh threshold A7, keeping the washing machine running at the fifth rotating speed until the dehydration program is finished.
And S1610, when the washing machine operates at the sixth rotating speed, if the acceleration a is less than or equal to the eighth threshold A8, controlling the washing machine to operate at the third rotating speed.
And S1611, if the acceleration a is greater than the eighth threshold A8 and less than or equal to the ninth threshold A9, controlling the washing machine to operate at the fourth rotating speed.
And S1612, if the acceleration a is greater than the ninth threshold a9 and less than or equal to the tenth threshold a10, controlling the washing machine to operate at the fifth rotation speed.
And S1613, if the acceleration a is greater than a tenth threshold A10, keeping the washing machine running at the sixth rotating speed until the dehydration program is finished.
According to the control method of the washing machine, the vibration displacement of the whole machine is easily caused by resonance when the washing machine is dehydrated at a low speed, and the vibration displacement of the washing machine in a low-speed state is violent in expression, obvious in regularity and easy to control; when the washing machine is used for low-speed dehydration, the vibration acceleration of the whole machine is small, the acceleration change is not obvious along with the change of the eccentricity, and the detection result is easily influenced by external interference. So that the rotation speed of the washing machine is controlled by the displacement of the outer tub at a low rotation speed. The vibration displacement of the washing machine is affected and aggravated by the whole machine system (a spring, a damper, a balance weight, assembly factors and the like) during high-speed dehydration, and is not only related to the eccentric size in the barrel; and the vibration that the eccentric mass in the inner tube arouses directly transmits to outer bucket, because acceleration sensor installs on outer bucket, what directly gathered is the acceleration signal of outer bucket, and the eccentric size in the reaction bucket of acceleration signal can be more accurate. The rotation speed of the washing machine is controlled by the acceleration of the outer tub at the time of high rotation speed. Different detection modes are adopted by the low rotating speed and the high rotating speed, so that the rotating speed can be controlled according to the actual moving condition of the outer barrel, and the vibration of the washing machine during dehydration can be reduced.
