Abstract

Disclosed herein are a washing machine, which includes a main body in which a main entrance is formed at a front thereof, a tub that is provided inside the main body, and a main door that is coupled to the main body to open and close the main entrance and includes a glass member and a holder member. The glass member includes a flange portion that is coupled to the holder member, and a body portion that protrudes toward an inside of the tub and has an auxiliary entrance formed therein for inputting laundry to the inside of the tub while the main door is closed. With this configuration, opening the auxiliary door and additionally inputting laundry is possible during a washing cycle.

First claim

What is claimed is:

1. A washing machine, comprising:
a main body having a main entrance provided at a front side of the main body;
a tub disposed inside the main body; and
a main door configured to open and close, respectively, the main entrance, the main door including
a holder member,
a glass member including
a flange portion coupled to the holder member so that the glass member is supported by the holder member,
a body portion that, while the main door is closed, protrudes toward an inside of the tub, and
an auxiliary entrance provided at the body portion to input laundry inside the tub while the main door is closed;

an auxiliary door that opens and closes the auxiliary entrance;
a frame unit coupled to the glass member to frame the auxiliary entrance; and
a packing member coupled to the glass member to provide a seal between the glass member and the frame unit.

2. The washing machine of claim 1 , wherein the auxiliary door rotates to open and close the auxiliary entrance.

3. The washing machine of claim 1 , wherein the frame unit includes a hinge portion rotatably supporting the auxiliary door so that the auxiliary door rotates to open and close the auxiliary entrance.

4. The washing machine of claim 1 , wherein the frame unit includes:
a catch portion that, while the auxiliary door closes the auxiliary entrance, keeps the auxiliary door in a closed state unless a force exceeding a predetermined level is applied to the auxiliary door.

5. The washing machine of claim 1 , wherein the frame unit includes:
a front frame at a front side of the glass member, and
a rear frame at a rear side of the glass member and coupled to the front frame.

6. The washing machine of claim 5 , further comprising:
an engaging member that couples the front frame and the rear frame together.

7. The washing machine of claim 1 , further comprising a locking unit that locks the auxiliary door in a closed state.

8. The washing machine of claim 1 , wherein the auxiliary door includes a sealing member that closely contacts the frame unit.

9. The washing machine of claim 1 , further comprising:
a hinge member coupled to the glass member to support the auxiliary door so that the auxiliary door rotates to open and close the auxiliary entrance.

10. The washing machine of claim 9 , wherein a through hole is formed in the glass member to couple with the hinge member.

11. A washing machine comprising:
a main body having a main entrance provided at a front side of the main body;
a tub disposed inside the main body; and
a main door configured to open and close, respectively, the main entrance, the main door including
a holder member,
a glass member including
a flange portion coupled to the holder member so that the glass member is supported by the holder member,
a body portion that, while the main door is closed, protrudes toward an inside of the tub, the body portion including a slanted upper portion, a slanted lower portion, and an intermediate portion that is vertically arranged between the slanted upper portion and the slanted lower portion, and
an auxiliary entrance provided at the intermediate portion of the body portion to input laundry inside the tub while the main door is closed.

12. A washing machine comprising:
a main body having a main entrance provided at a front side of the main body;
a tub disposed inside the main body; and
a door assembly including
a main door configured to open and close, respectively, the main entrance,
a holder member,
a glass member including
a flange portion coupled to the holder member so that the glass member is supported by the holder member,
a body portion that, while the main door is closed, protrudes toward an inside of the tub, and
an auxiliary entrance disposed in the body portion to input laundry inside the tub while the main door is closed;

an auxiliary door to open and close the auxiliary entrance; and
a frame unit including
a front frame at a front side of the glass member, and
a rear frame at a rear side of the glass member and coupled to the front frame,
