Abstract

A washing machine includes: a cabinet having a first opening and a washing space formed therein; and a door assembly provided to open and close the first opening, wherein the door assembly includes: a door body having a second opening and corresponding to the first opening and provided to rotate relative to the cabinet; door glass having a glass hole communicating with the inside of the cabinet and coupled with the rear surface of the door body; a guide duct that connects the second opening and the glass hole; and a sealing member. The sealing member can prevent washing water or internal air from escaping from the door assembly.

First claim

What is claimed is:

1. A washing machine comprising:
a cabinet having a first opening and having a washing space formed therein; and
a door assembly provided to open and close the first opening, wherein the door assembly includes:
a door body having a second opening,
a door glass having a glass hole,
a guide duct configured to connect to the second opening of the door body and the glass hole of the door glass; and
a sealing member configured to couple the glass hole and the guide duct.

2. The washing machine of claim 1 , further comprising an auxiliary door configured to open and close the second opening.

3. The washing machine of claim 1 , wherein the sealing member includes a sealing cap having one end connected with one end of the guide duct and an other end connected with the glass hole.

4. The washing machine of claim 3 , wherein the sealing cap includes a coupling groove formed to be concave along a circumference of the one end of the sealing cap, and the one end of the guide duct is inserted into and coupled to the coupling groove.

5. The washing machine of claim 3 , wherein:
the sealing cap includes a catcher extending from the sealing cap along a circumference of the other end of the sealing cap; and
the guide duct includes a catching protrusion protruding from the one end of the guide duct along an outer circumferential surface thereof to catch a catching groove.

6. The washing machine of claim 4 , wherein the sealing member includes a sealing ring having a ring shape and located between the coupling groove and a coupling protrusion.

7. The washing machine of claim 3 , wherein the sealing member further includes a sealing agent configured to attach the other end of the sealing cap to the door glass.

8. The washing machine of claim 7 , wherein the sealing cap further includes a sealing cap contact surface which faces the door glass and to which the sealing agent is applied.

9. The washing machine of claim 8 , wherein the sealing cap includes a contact rib protruding farther from an outer edge of the sealing cap contact surface than the sealing cap contact surface to prevent the sealing agent from being leaked.

10. The washing machine of claim 9 , wherein the contact rib includes:
a first contact rib which is adjacent to the sealing cap contact surface; and
a second contact rib formed to be separated a predetermined distance from the first contact rib.

11. The washing machine of claim 10 , wherein the sealing member further includes a rib contact ring disposed between the first contact rib and the second contact rib to seal a gap between the sealing cap and the door glass.

12. The washing machine of claim 3 , wherein the door glass includes an introduction preventing protrusion formed around the sealing member and formed to protrude toward an inside of the cabinet.
