Abstract:
A washing machine drainage apparatus, a washing machine, and a control method. The drainage apparatus comprises a drain valve body (1), a water inlet (2), and a water outlet (3). The water inlet (2) is in communication with a drainage outlet of an outer drum of the washing machine. The drain valve body (1) is provided therein with a granule accommodating/releasing cavity (5) in communication with the water inlet (2) and also comprises a water storage mechanism provided therein with a water storage cavity (10). The water storage mechanism is in communication respectively with the water inlet (2) and the granule accommodating/releasing cavity (5) and used for storing water and releasing water to the granule accommodating/releasing cavity (5). The apparatus allows water to be introduced slowly into the granule accommodating/releasing cavity during a spin-drying process of the washing machine, thus preventing cleaning granules from colliding and bouncing between inner and outer drums and thus generating loud noises, also preventing damages to the surfaces of the cleaning granules, and ensuring cleaning effects.
