Claim Text:
1. A rinsing method that occurs after a washing step in a vertical-axis washing machine having a tub, a basket within a tub for holding textiles, a pump located below the tub, a motor connected to a pulley to rotate the basket, an admission valve, and a spraying device configured to spray water into an upper part of the tub; having finished the washing phase and being the coupling system in centrifuge mode, the method comprising the following steps: a) activating the pump after the washing step and activating the admission valve while the basket is totally stopped; b) spraying water into the basket; c) activating the motor and rotating the pulley at least one revolution generating at least a pulse that rotates the basket at a predetermined angle while the cloth load is sprayed to uniformly hydrate it, therefore soaking textiles contained in the basket; d) deactivating the motor and repeating steps b) and c) until the basket rotates at least one revolution to soak the textiles within the basket; e) once the basket has rotated at least one revolution, deactivating the admission valve, thus stopping the water flow towards the textiles; f) initializing dehydration of the cloth load by activating the motor to initiate a centrifuge ramp until the basket reaches a medium speed oscillating in a range of 200 to 450 rpm, wherein once the centrifuge force is greater than the gravity force the fresh water that soaks the textile passes through the rest of the cloth load diluting and dragging the washing liquor in the textiles towards the basket wall; the diluted washing liquor that passes through the basket wall is collected in the tub bottom and extracted by the pump, draining said diluted washing liquor to the outside of the tub; g) deactivating the motor once the medium speed has been reached; h) sensing the speed of the basket until the speed of the basket reaches a minimum speed of zero rpm or close to zero rpm, therefore reducing centrifuge force such that gravity force is greater than centrifuge force within the basket thus stopping cloth dehydration due to the centrifugal force; i) hydrating and dehydrating the cloth load in order to remove washing liquor contained in the cloth load by repeating steps b) to f) at least once; j) initiating a final dehydration step by activating the motor; k) deactivating the motor after the predetermined time period of step j); until reaching a final speed; l) waiting until the basket reaches a speed equal to zero; and m) deactivating the pump.
