Method for controlling a spin cycle of a washing machine and washing machine

Method for controlling a spin cycle of a washing machine, the washing machine comprising:

• a suspended group including a rotative drum contained in a dampened enclosure supported on a suspension mechanism, the rotative drum being connected to the dampened enclosure through a driving shaft actuated through a variable-speed motor to produce a rotation of the rotative drum around a rotation axis;
• a two axes accelerometer connected to an electronic control and supported on the suspended group to determine an acceleration of the rotative drum in two orthogonal axes perpendicular to the rotation axis;
• wherein the method comprises:
• performing a centrifugal cycle by accelerating the rotative drum to a centrifugal speed adjusted to retain clothes contained in the rotative drum against an inner perimeter of the rotative drum by a centrifugal force and by draining water from the dampened enclosure;
• capturing, during the centrifugal cycle by said two-axis accelerometer, vibration data relative to the vibration of the suspended group, produced by weight offset of the clothes;
• analyzing, during the centrifugal cycle and by the electronic control unit, the vibration data, provided by the two axes accelerometer, detecting a vibration data variation over time, indicative of a weight reduction of the clothes due to the loss of water;
• analyzing, during the centrifugal cycle and by the electronic control unit, the vibration data variation to determine a stabilization of the vibration data variation over time when the vibration data decreases at a pace below a predefined stabilization threshold, indicative of the steadiness of the weight reduction of the clothes due to end of the loss of water;
• and
• triggering an end of the centrifugal cycle in response to the stabilization of the vibration data variation.
