Abstract

The invention discloses a spin drying control method and device of a washing machine and the washing machine. The method comprises the following steps: when a spin drying procedure is executed, collecting the speed of a spin drying drum and the acceleration of the spin drying drum in the vibration direction in real time; calculating the vibration displacement of the spin drying drum in the vibration direction according to the speed and the acceleration; when the speed of the spin drying drum reaches the resonance point speed, judging whether the vibration displacement is greater than a preset displacement threshold corresponding to the resonance point speed; if so, controlling the washing machine to perform loose shaking work; otherwise, controlling to increase the speed of the spin drying drum to the stable-gear speed, and judging whether the vibration displacement is greater than the preset displacement threshold corresponding to the stable-gear speed; and if the vibration displacement is less than or equal to the preset displacement threshold corresponding to the stable-gear speed, controlling to continuously increase the speed of the spin drying drum to the next stable-gear speed. By adopting the method disclosed by the invention, high-speed vibration of the spin drying drum can be effectively reduced, and the spin drying time is shortened while the spin drying effect is improved.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a washing machine dehydration control method, a washing machine dehydration control device and a washing machine. Background technique [0002] When the drum washing machine is dehydrating, when the clothes in the drum are not evenly distributed, it will cause a large vibration of the drum washing machine, which seriously affects the user experience and reduces the service life of the drum washing machine. The drum washing machine motor has the function of detecting load unbalance. When the unbalance is detected, the vibration can be reduced when the drum washing machine dehydrates by adjusting the speed or readjusting the load distribution. [0003] At present, there are two methods for detecting the dehydration vibration of the drum washing machine: 1. During the dehydration low-speed stage (rotation speed ≤ 150 rpm), detect the speed fluctuation of the steady-state ...
