METHOD FOR WASHING AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/036421
Kind Code:
A1
Abstract:
A washing machine includes an outer tub (4) and an inner tub (5) rotatably provided in the outer tub (4), a spray nozzle (12) spraying wash water into the tub, a circulation passage (17) connecting the outer tub (4) to the spray nozzle (12), and a filter (16) provided in series with the circulation passage (17). A first pump (14) directs wash water from the outer tub (4) to the circulation passage (17) and to the spray nozzle (12) so that foreign substances suspended in the wash water can be collected in the filter (16). A drain passage (19) between the filter (16) and spray nozzle (12) connects the outer tub (4) to the circulation passage (17). A second pump (18) directs the wash water supplied to the circulation passage (17) through the drain passage (19) such that the wash water passes through the filter (16) in a reverse direction and thus the foreign substances collected in the filter (16) are exhausted out of the washing machine together with the wash water.
