Is made (S10). Thereafter, the inflating step (S20) of stirring the washing water dipped in the inner tank 115 and the outer tank 122 to form a stirring water flow is performed. By the stirring water flow formed in the inflating step (S20), foreign matter such as seams buried in the laundry is effectively separated.

Thereafter, the washing water is raised between the outer tub 122 and the inner tub 115 by centrifugal force, and passes through a lint filter 120 provided in the outer tub cover 114 to form a circulating water stream re-watered into the inner tub 115. The filtering step S20 is performed. In the filtering step (S20), foreign substances such as seams contained in the circulation water stream are filtered by the lint filter 120. As the above-mentioned circulating water is continuously filtered while circulating between the inner tank 115 and the outer tank 120, foreign matters such as seams contained in the wash water are effectively filtered, so that the foreign matters such as clean laundry, as well as washing the seams are washed. By draining with water, problems such as clogging of the drain hose 142 or failure of the drain pump 144 are prevented.

On the other hand, since the inflating step (S20) and the filtering step (S30) is sequentially repeated (S40), the foreign matters such as seams attached to the laundry is separated, and the collection of the foreign matters by the lint filter 120 is continuously Iteratively, the filtering efficiency is improved.

For example, when performing only the filtering step (S30), the laundry is stuck to the side of the inner tank 115 by the centrifugal force, the laundry is agglomerated, and thus there is a problem that foreign matters such as seams and the like are not easily separated from the laundry. On the contrary, in the present embodiment, since the foreign matter is separated from the laundry by forming the stirring water stream in the inflating step (S20), the foreign matter is filtered while the circulating water including the separated foreign material passes through the lint filter 120. Therefore, the removal of foreign substances in the wash water is very efficient.

On the other hand, in consideration of the time taken for the circulation passage to complete one cycle, it is preferable that the filtering step S0 is longer than the inflating step S20.
