Washing machine
Disclosed is a washing machine having an improved wire connection structure for electrically connecting electrical components. The washing machine includes a cabinet which has a first electrical component, forms an exterior, and has an opening through which laundry is inserted; a door provided with a second electrical component, and configured to open and close the opening; a wire which electrically connects the first electrical component and the second electrical component; and a hinge which has a wire guide portion for coupling the door to the cabinet so as to be rotatable about a rotating axis and for guiding the wire.
1. A washing machine comprising:
a cabinet having an opening at a front side;
a drum rotatably disposed inside the cabinet;
a door configured to open or close the opening;
a hinge configured to pivotably couple the door to the cabinet; and
a wire extending from an inside of the cabinet to the door,
wherein the hinge comprises:
a hinge body coupled to the cabinet,
a first hinge arm,
a second hinge arm that is spaced apart from the first hinge arm along a direction of a rotating axis, and
a wire guide portion formed at the first hinge arm to accommodate the wire,
wherein the first hinge arm includes a first surface facing the second hinge arm and a second surface opposite the first surface, and
wherein the wire guide portion is formed to be recessed at the second surface.
2. The washing machine of claim 1 , wherein the hinge further comprises a protrusion protruding from the first hinge arm to form the rotating axis of the door.
3. The washing machine of claim 2 , wherein the hinge further comprises a hinge cover coupled to the first hinge arm and the protrusion to cover the wire guide portion.
4. The washing machine of claim 3 , wherein the hinge further comprises a fixing ring configured to enclose the protrusion and an end portion of the hinge cover to couple the end portion of the hinge cover to the protrusion.
5. The washing machine of claim 4 , wherein the wire passes through the fixing ring.
6. The washing machine of claim 4 , wherein the protrusion includes an incised portion extending from the first hinge arm along an exterior surface of the protrusion.
7. The washing machine of claim 6 , wherein the door includes an accommodating recess configured to accommodate the fixing ring enclosing the protrusion and the end portion of the hinge cover.
8. The washing machine of claim 7 , wherein the accommodating recess allows the fixing ring to rotate about the rotation axis of the protrusion.
9. The washing machine of claim 7 , wherein the wire passes through the accommodating recess when the fixing ring is inserted to provide power to an electrical component in the door.
10. The washing machine of claim 6 , wherein the end portion of the hinge cover completes an outer circumference of the protrusion at the incised portion.
11. The washing machine of claim 2 , wherein the protrusion includes an incised portion extending from the first hinge arm along an exterior surface of the protrusion.
12. The washing machine of claim 11 , wherein the incised portion forms a wire inlet together with an end portion of the hinge cover.
13. The washing machine of claim 2 , wherein the protrusion includes:
a first protrusion formed to protrude in a first direction from the first hinge arm, and
a second protrusion formed to protrude in a second direction opposite to the first direction.
14. The washing machine of claim 13 , wherein the hinge further includes a protrusion cover configured to be coupled to the second protrusion to protect the second protrusion.
15. The washing machine of claim 1 , wherein the first hinge arm extends from the hinge body toward the front side of the cabinet.
16. The washing machine of claim 1 , wherein the wire is disposed in the recessed wire guide portion.
17. The washing machine of claim 1 , further comprising:
a first electrical component provided at the cabinet; and
a second electrical component provided at the door,
wherein the wire connects the first electrical component and the second electrical component.
18. The washing machine of claim 1 , wherein a wire outlet is formed at one surface of the hinge body to allow the wire to exit from the wire guide portion.
19. The washing machine of claim 18 , wherein:
the cabinet includes a through-hole, and
the wire exiting from the wire outlet passes through the through-hole to enter the cabinet.
20. The washing machine of claim 18 , wherein the wire outlet is spaced apart from at least one of the first hinge arm or the second hinge arm.
