FIG. 14 , in order to prevent water flowing into thefilter device 200 from passing through thefilter 227, the second a (2a)filter driving device 236 may drive thefirst damper 236a to allow the water flowing into thefilter device 200 to be directed to thebypass flow path 210a of thefilter housing 210, and the second b (2b)filter driving device 237 may drive thesecond damper 237a to allow water passing through thebypass flow path 210a to be discharged to the outside of thefilter device 200. - Accordingly, in response to the wash cycle, the rinse cycle, or the spin-dry cycle, the
filter device 200 shown inFIGS. 12 to 14 may allow water, which is discharged from thedrain pump 80, to pass through the circulation flow path or to pass through the drain flow path, thereby collecting various sizes of foreign substances. -
FIG. 15 illustrates a washing machine according to another embodiment of the disclosure. - Referring to
FIG. 15 , awashing machine 2 according to another embodiment of the disclosure will be described. The same reference numerals designate the same components as those of thewashing machine 1 shown inFIG. 2 , and detailed descriptions thereof may be omitted. - Referring to
FIG. 15 , thewashing machine 2 may include thesame filter device 100 as thefilter device 100 shown inFIG. 2 . Thefilter device 100 may be located at the upper rear side of thetub 20. Thedrain pump 80 may pump the water, which flows from thetub 20, to thefilter device 100. With this configuration, thewashing machine 2 shown inFIG. 15 may efficiently arrange thefilter device 100 in a limited space inside thecabinet 10. - As is apparent from the above description, a washing machine and a clothing treatment apparatus may collect various sizes of foreign substances by including a filter provided with a plurality of filter members.
- Further, a washing machine and a clothing treatment apparatus may include a controller configured to change a flow path, thereby allowing washing water to selectively pass through one filter member among a plurality of filter members of a filter.
- Further, a washing machine and a clothing treatment apparatus may include a filter including a plurality of filter members provided to collect various sizes of foreign substances, thereby reducing a space occupied by the filter while maintaining a performance of the filter.
- Although a few embodiments of the disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
