Control method of a laundry machine

A method of operating a laundry machine having a drum with an axis of rotation through a center of the drum, the method comprising rotating the drum in a first motion, comprising:

• (a) rotating the drum in a first direction at a first predetermined rotational speed such that a reference point on the drum, initially positioned at an initial position, rotates about the axis of rotation to a first predetermined position, wherein the reference point is any point on a side of the drum;
• (b) when the reference point has reached the first predetermined position, changing the direction of rotation of the drum and rotating the drum in a second direction opposite the first direction at the first predetermined rotational speed such that the reference point of the drum travels back through the initial position toward a second predetermined position;
• (c) when the reference point has reached the second predetermined position, changing the direction of rotation of the drum and rotating the drum in the first direction such that the reference point travels back toward the initial position;
• and
• (d) applying any one or more of the following during at least one of the step (a), step (b) or step (c):
• (i) a rotational speed of the drum in the first and second directions is greater than 45 RPMs;
• or
• (ii) the reference point of the drum is greater than an absolute value of 90 degrees from the initial position at the first and second predetermined positions;
• or
• (iii) changing direction of rotation of the drum comprises braking a motor that drives the drum or changing a rotation direction of the motor to apply a reverse torque to the drum.

A method of operating a laundry machine having a drum with an axis of rotation through a center of the drum, the method comprising rotating the drum in a first motion, comprising:

• rotating the drum at a first predetermined rotational speed such that a first centrifugal force generated by the rotation of the drum at the first predetermined rotational speed causes a laundry item positioned in the drum to cling to an inner surface of the drum as the drum rotates at the first predetermined rotational speed;
• rotating the drum at a second predetermined rotational speed such that a second centrifugal force generated by the rotation of the drum at the second predetermined rotational speed is insufficient for the laundry item to cling to the inner surface of the drum as the drum rotates at the second predetermined rotational speed;
• and
• rotating the drum at a third predetermined rotational speed such that a third centrifugal force generated by the rotation of the drum at the third rotational speed causes the laundry item to be drawn back to the inner surface of the drum and cling to the inner surface of the drum as the drum rotates at the third predetermined rotational speed.
