Adaptative washing system for different water and/or load levels

An adaptive washing method implemented in a washing machine, wherein the washing machine includes a cabinet that supports a tub which houses a basket that rotates concentrically inside the tub, the basket being driven by a motor which is mechanically coupled to an agitator and said basket, a clutch that allows coupling and uncoupling between the basket and agitator, a user interface that allows the user to select water levels, type of laundry, washing intensity, rinse mode, and an electronic control that controls actuators by means of drivers, a level sensor and a rotor position sensor inside the motor, and a spray system, said electronic control further comprising a memory and a processor configured to carry out the method, wherein the method comprises:

• a. laundry arrangement sequence, which evenly distributes the objects to be washed inside the basket;
• b. checking, by the electronic control, the water level to determine the water level inside the tub by means of the level sensor that is in communication with the electronic control;
• c. filling, by a valve, the tub to a minimum level, with the reading from step b. the electronic control determines the volume of water to be admitted in the tub in order to carry out step d;
• d. load sensing sequence, wherein the electronic control, by the rotor position sensor inside the motor, determines the amount of objects to be washed arranged in the basket (load) and the type of objects to be washed based on the resistance that said load offers to the movement of the agitator or propeller, wherein the load sensing sequence is carried out with a minimum volume of water or without water on the tub;
• e. sequence of filling the tub to washing level, wherein the water level inside the tub required for step f. is determined according to the user preference of the water level to be used selected in the user interface, as well as with the data of step d;
• f. progressive agitation sequence, wherein according to the user preferences selected in the user interface regarding the level of water to be used, the type of laundry, and wash intensity, together with the data of the load level determined in step d. and based on a table of initial values as well as variance of the agitation patterns, a plurality of progressive agitation patterns are formed, by the electronic control, within an agitation block;
• wherein each of the plurality of progressive agitation patterns comprises a period of time during which the agitator or propeller is operated with a length of arc or paddle stroke in a clockwise and counterclockwise direction, with a paddle stroke frequency that is determined by strokes per minute (spm) that cause agitation on the objects to be washed inside the basket, wherein the period of time during which the agitator or propeller is operated varies incrementally or decrementally for each of the plurality of progressive agitation patterns, wherein a length of the arc or paddle stroke varies incrementally or decrementally for each of the plurality of agitation patterns, wherein the strokes per minute vary incrementally or decrementally for each of the plurality of agitation patterns;
• g. arrangement and balancing agitation sequence, in which the objects to be washed are spread and distributed inside the basket, avoiding excessive imbalance when spinning the basket;
• h. dehydration, wherein the basket is rotated to generate a centrifugal force greater than the force of gravity, which causes the dehydration of the objects to be washed inside the basket;
• i. rinse, wherein the wash liquor residues are removed, hydrating the objects to be washed followed by dehydration.
