Abstract

The embodiment of the disclosure provides a dehydration control method, an electronic device and a clothes treatment device. The method comprises the steps of conducting eccentric detection on an inner cylinder at a second preset rotating speed to obtain a first eccentric detection value, starting a water inlet valve to feed water to an outer cylinder in response to the fact that the first eccentric detection value is smaller than or equal to the preset eccentric value, enabling the preset eccentric value to be an allowable eccentric value of the inner cylinder at a third preset rotating speed, enabling the third preset rotating speed to be larger than the second preset rotating speed, controlling the water inlet valve to be closed in response to the fact that preset conditions are met, controlling the inner cylinder to rotate at the third preset rotating speed and maintaining the first preset time, and adopting different dewatering execution strategies according to the water level change value of the outer cylinder and the water level of the outer cylinder at the closing time of the water inlet valve after the rotating speed of the inner cylinder is increased to the third preset rotating speed. According to the method and the device, the diagonal eccentricity can be identified through the water level change value, so that different dewatering strategies are adopted, and the phenomenon of cylinder collision caused by the diagonal eccentricity is avoided.
