Foreign materials filtering apparatus and washing machine having the same
In a foreign materials filtering apparatus and a washing machine having the same, a filter cover is installed at a washing water circulating duct disposed inside a washing tub, and a net filter is installed at an inner side of the filter cover. Accordingly, the net filter is prevented from directly contacting laundry, thereby preventing the not filter and the laundry from being damaged. Furthermore, since the net filter is covered by the filter cover, the entire appearance is enhanced. Additionally, when the net filter is mounted at the filter cover, the filter unit becomes modularized to be facilitate a detachable mounting.
1. A foreign materials filtering apparatus, comprising:
a washing water circulating duct having one or more washing water inlets;
a filter cover mounted so as to cover the washing water inlets; and
a net filter disposed between the washing water circulating duct and the filter cover, for filtering foreign materials from washing water introduced through the washing water inlets,
wherein a filter fixing rib for coupling the net filter for modularization is formed at the filter cover,
wherein the filter cover is provided with drain holes so as to communicate with the washing water inlets, and
wherein an interval protrusion is formed at the periphery of the drain holes so as to separate the net filter from the filter cover.
2. The foreign materials filtering apparatus of claim 1 , wherein the washing water circulating duct is mounted on an inner circumferential surface of a washing tub so as to form a washing water guiding passage together with the inner circumferential surface of the washing tub.
3. The foreign materials filtering apparatus of claim 2 , wherein a washing water guiding protrusion is protrudingly formed in a vertical direction at right and left sides of a rear surface of the washing water circulating duct facing the washing tub, and the one or more washing water inlets are formed inside the washing water guiding passage formed by the washing water guiding protrusion.
4. The foreign materials filtering apparatus of claim 1 , wherein a hook protrusion is formed at one of the washing water circulating duct and the filter cover, and a hook groove for detachably mounting the hook protrusion is formed at the other.
5. The foreign materials filtering apparatus of claim 1 , wherein the washing water circulating duct and the filter cover are coupled to each other by an additional coupling member.
6. The foreign materials filtering apparatus of claim 1 , wherein the filter cover comprises:
a cap for covering the washing water inlet of the washing water circulating duct; and
a handle coupled to the cap thus to be mounted at the washing water circulating duct.
7. The foreign materials filtering apparatus of claim 6 , wherein the cap and the handle are formed of different materials from each other.
8. The foreign materials filtering apparatus of claim 6 , wherein the handle is formed of a material softer than that of the cap.
9. The foreign materials filtering apparatus of claim 1 , wherein the interval protrusion is formed in a belt shape so as to surround the drain holes.
10. The foreign materials filtering apparatus of claim 9 , wherein drain guiding holes or drain guiding grooves for guiding washing water to be introduced into the drain holes are formed at the interval protrusion.
11. The foreign materials filtering apparatus of claim 1 , wherein the interval protrusion is formed in plurality with a certain gap therebetween along the periphery of the drain holes.
12. The foreign materials filtering apparatus of claim 1 , wherein the filter cover comprises:
a cap portion for covering the washing water inlets of the washing water circulating duct; and
a handle portion integrally formed at the cap portion and mounted at the washing water circulating duct.
