Abstract
A washing machine provided with recirculation with controlled flow. It further presents a method to control the level of the washing liquid, associated to the said machine, providing economy of resources such as water and cleaning products, guaranteeing an effective washing of clothes and similar articles, still associated with a decreases foam formation and lower nose emissions during the process, thus improving the operation of the equipment. The washing machine is provided with a washing tub (2), a basket (3), a two-way pump (7), level sensor (5), pool (6), recirculation hose (9), drainage hose (8) and control circuit.
Claims9
A washing and water recirculation method for a washing machine comprising:
- supplying liquid to a tub until it reaches a predefined level;
- continuously recirculating the liquid inside the tub with higher outflow out of the tub than a liquid drain basket's outflow to the tub;
- monitoring a liquid level in a pool of the tub, wherein the pool is formed as a recess in the bottom of the tub;
- recirculating the liquid with a constant outflow out of the tub until the liquid level in the pool reaches a minimum liquid level and a liquid level of the liquid drain basket reaches a maximum liquid level;
- in response to determining the liquid level in the pool is at a minimum liquid level, controlling a speed of a pump for recirculating the liquid to continuously recirculate liquid in the tub so that the outflow out of the tub is equal to the liquid drain basket's outflow to the tub;
- moving agitator elements to effect a washing operation;
- draining the liquid from the tub;
- and
- spinning the liquid drain basket to effect centrifugation.
