Abstract

In a method for cleaning the foreign materials filtering, foreign materials collected in a foreign materials filtering space can be easily removed under a filter unit is separated from or is mounted at a filter cover unit. As a result, can be solved the conventional problems that a net filter has to be kept inside out at the time of a cleaning process to cause a user's hands to become dirty, and there is a difficulty in removing foreign materials from the net filter due to a fibrous characteristic of the net filter. Accordingly, a cleaning operation for the foreign materials filtering apparatus can be facilitated.

Claims (22)

1. A foreign materials filtering apparatus detachably installed at a washing water circulation duct which circulates washing water, the apparatus comprising:

a handle coupled to the washing water circulation duct, and having a round ring shape;

a front filter mounted to an inner circumferential surface of the handle, and having a mesh;

a rear filter hinge-coupled to the front filter at a lower side, and forming a foreign materials collecting space; and

a cap configured to an outer circumferential surface of the handle.

2. The apparatus of claim 1 , wherein hooks detachably coupled to hook coupling holes of the washing water circulating duct are formed at the handle.

3. The apparatus of claim 2 , wherein coupling protrusions are formed on side surfaces of the front filter, and coupling holes for inserting the coupling protrusions are formed at the handle.

4. The apparatus of claim 1 , wherein coupling protrusions are formed on side surfaces of the rear filter, and coupling holes for inserting the coupling protrusions of the rear filter are formed on side surfaces of the front filter.

5. A washing machine, comprising:

a reservoir disposed in a cabinet, and containing washing water therein;

a washing tube disposed in the reservoir, and accommodating laundry therein;

a pulsator disposed at a bottom of the washing tub, and configured to stir the washing water;

a washing water circulation duct disposed between an inner wall and an outer wall of the washing tub; and

a foreign materials filtering apparatus detachably mounted to the washing water circulation duct, and configured to filter foreign materials from circulating washing water,

wherein the foreign materials filtering apparatus comprises:

a handle coupled to the washing water circulation duct, and having a round ring shape;

a front filter mounted to an inner circumferential surface of the handle, and having a mesh;

a rear filter hinge-coupled to the front filter at a lower side, and forming a foreign materials collecting space; and

a cap configured to an outer circumferential surface of the handle.

6. The washing machine of claim 5 , wherein hooks detachably coupled to hook coupling holes of the circulating duct are formed at the handle.

7. The washing machine of claim 6 , wherein coupling protrusions are formed on side surfaces of the front filter, and coupling holes for inserting the coupling protrusions are formed at the handle.

8. The washing machine of claim 5 , wherein coupling protrusions are formed on side surfaces of the rear filter, and coupling holes for inserting the coupling protrusions of the rear filter are formed on side surfaces of the front filter.
