WASHING MACHINE AND METHOD FOR MEASURING OF FOAM AMOUNT FOR THE SAME Russian patent published in 2007 - IPC D06F39/06 D06F33/02 

FIELD: mechanical engineering.

SUBSTANCE: method involves measuring amount of foam in washing machine at water drainage stage using foam flow rate characteristics; said foam measuring process includes steps of determining during water drainage operation whether water level reaches during predetermined water drainage period water level indicative of complete water drainage; determining whether water level reaches the level allowing foam amount to be measured during predetermined foam drainage period by providing controlling of water drainage apparatus in a manner enabling switching on and off of water drainage apparatus if during predetermined water drainage period water level does not reach the level indicative of complete water drainage level, and in a manner enabling measurement of foam amount by controlling water drainage apparatus in a manner enabling switching on and off of water drainage apparatus within predetermined water level range if during predetermined foam drainage period water level reaches the level indicative of level allowing foam amount to be measured.

EFFECT: improved quality of washing cloths.
