Door lock device of drum washing machine and washing machine having the same
First Claim
1. A drum washing machine comprising:
- a body having an opening;
a door to open or close the opening;
a door switch to lock the door; and
a door lock device coupled to the door switch,wherein the door lock device includes a door lever pivotally installed to the door and selectively inserted into or separated from the door switch and a door handle in contact with the door lever,wherein the door lever includes a hook portion having a holding protrusion selectively caught by or released from the body, a rotating portion rotatably coupled to the door and having a rotation center, and a handle contact portion coming into contact with the door handle and a bent portion formed between the hook portion and the rotating portion to enable release of coupling between the door and the body by force of a predetermined magnitude or greater applied to the door, andwherein the holding protrusion extends from the hook portion in a first direction, the handle contact portion extends from the rotating portion in a second direction, and the bent portion is bent in a third direction between the first direction and the second direction while protruding toward a center of the door.

Abstract
Disclosed herein are a door lock device of a drum washing machine and a drum washing machine having the same, a door of which is opened by force of a predetermined magnitude or greater. The door opening is accomplished by providing a door lever of the door lock device with a bent portion. The bent portion formed at the door lever creates a predetermined angle X° between a contact point between a holding protrusion of the door lever and a raised portion of a body of the washing machine, a center point of a door lever shaft, and a contact point between a handle contact portion of the door lever and a door handle, allowing the door to be opened upon receiving force of a predetermined magnitude or greater.

8. A door lock device of a drum washing machine, the door lock device comprising:
-
a door lever inserted into a body of the drum washing machine; and a door handle in contact with the door lever and rotatablv coupled to the door, wherein the door lever includes a hook portion having a holding protrusion selectively caught by or released from the body, a rotating portion rotatably coupled to the door and having a rotation center, and a handle contact portion coming into contact with the door handle and a bent portion formed at a position thereof to enable release of coupling between the door and the body by force of a predetermined magnitude or greater applied to the door, wherein the holding protrusion extends from the hook portion in a first direction, the handle contact portion extends from the rotating portion in a second direction, and the bent portion is bent in a third direction between the first direction and the second direction while protruding toward a center of the door, and wherein an angle defined between an end of the hook portion, the rotation center of the rotating portion, and a contact point between the handle contact portion and the door handle is between about 35°
to about 75°

15. A door lock device of a drum washing machine, the door lock device comprising:
-
a door lever inserted into a body of the drum washing machine; and a door handle in contact with the door lever, wherein the door lever includes a hook portion having a holding protrusion selectively caught by or released from the body, a rotating portion rotatably coupled to the door and having a rotation center, a handle contact portion coming into contact with the door handle and a connecting portion to connect the hook portion and rotating portion to each other, wherein an end of the hook portion and the rotation center of the rotating portion are spaced apart from each other at opposite sides of the connecting portion, to enable release of coupling between the door and the body by force of a predetermined magnitude or greater applied to the door, and wherein a horizontal distance D1 between the holding protrusion and the rotation center of the rotating portion is larger than a horizontal distance D2 between one end of the handle contact portion and the rotation center. - View Dependent Claims (16, 17)
