door lock switch 220 of the secondary door 80.
[0074] As shown in FIGS. 5A and 5B, the wire 300 may connect the
first and second electronic parts. Specifically, the wire 300 may
pass the hinge assembly 100 to connect the first and second
electronic parts. In other words, the wire 300 may penetrate the
hinge assembly 100 to connect the first and second electronic
parts.
[0075] In the process of connecting the first and second electronic
parts, at least a part of the wire 300 may be arranged along the
circumferential direction of the door 20. For example, at least a
part of the wire 300 placed in the door 20 may be arranged along
the circumferential direction of the door 20.
[0076] Furthermore, the wire 300 may be arranged between a first
shaft 140 (see FIG. 7) and a second shaft 150 (see FIG. 7) in the
process of passing the hinge assembly 100.
[0077] The second electronic part may be placed in the door 20.
Specifically, the second electronic part may be provided in the
door frame 21. For example, the second electronic part may be
equipped in the door 20 to be adjacent to the fixing hole of the
door 20 into which the locking part 81 of the secondary door 80 is
inserted. The open/close detection sensor 210 and the door lock
switch 220 may be arranged in the door frame 21 to face each other
with the fixing hole between them. The open/close detection sensor
210 and the door lock switch 220 may be placed on an inner side of
the door frame 21 corresponding to one side of the secondary door
80 facing the other side of the secondary door 80 hinged with the
door 20. For example, in a case that the bottom side of the
secondary door 80 is hinged with the door 20, the open/close
detection sensor 210 and the door lock switch 220 may be placed on
an inner side of the door frame 21 corresponding to the top side of
the secondary door 80.
[0078] The door 20 may further include a through hole 23 (see FIG.
11). The through hole 23 may be formed on the back of the door 20
facing the opening 16. In other words, the through hole 23 may be
formed on the back of the door frame 21 facing the opening 16.
[0079] The wire 300 connected to the open/close detection sensor
210 and the door lock switch 220 passes the through hole 23 to
reach the hinge assembly 100, and the wire 300 that reaches the
hinge assembly 100 passes the hinge assembly 100 to be connected to
the first electronic part equipped in the cabinet 10. In other
words, one end of the wire 300 may be connected to the open/close
detection sensor 210 and the door lock switch 220 and the other end
of the wire 300 may pass the through hole 23 to the hinge assembly
100 and then to the first electronic part. As such, the first and
second electronic parts may be connected by the wire 300 passing
through the hinge assembly 100, which may prevent most of the wire
300 from being exposed to the outside and thus from harming the
aesthetic appearance of the washing machine 1. Details of how the
wire 300 passes through the hinge assembly 100 will be described
later.
[0080] FIG. 6 shows a hinge assembly-coupled structure of a washing
machine, according to an embodiment of the present disclosure, and
FIG. 7 is an exploded view of a hinge assembly of a washing
machine, according to an embodiment of the present disclosure. FIG.

[0082] The first bracket 110 may be combined with the cabinet 10.
The second bracket 120 may be combined with the door 20. The link
unit 130 may be pivotally coupled to each of the first bracket 110
and the second bracket 120. In other words, the link unit 130 may
be arranged to connect the gap between the first bracket 110 and
the second bracket 120, thus allowing the door 20 to pivot forward
from the cabinet 10.
[0083] The first bracket 110 may be combined through the hinge
assembly installation part 19 formed on the front frame 11 of the
cabinet 10.
[0084] The hinge assembly installation part 19 may be arranged on
one side of the door contact 17. The hinge assembly installation
part 19 may include a first installation part 19a and a second
installation part 19b. The first installation part 19a may be
formed for the link unit 130 to penetrate. The second installation
part 19b may be formed for the first bracket 110 to be coupled and
fixed thereto.
[0085] It is preferable for the first installation part 19a to be
formed in a size equal to or larger than the size of the link unit
130 in order for the link unit 130 to penetrate and pivot.
[0086] The second installation part 19b may be arranged for the
first bracket 110 to be coupled with the front frame 11, and may be
formed on each of the top side and the bottom side of the first
installation part 19a. The second installation part 19b may have
the form of a hole.
[0087] The first bracket 110 may include an assembly hole 111. A
screw B passing through the second installation part 19b and the
assembly hole 111 may fix the first bracket 110 to the front frame
11.
[0088] The first bracket 110 may further include a first shaft hole
112 coupled to the first shaft 140.
[0089] The second bracket 120 may include a door supporter 121. The
second bracket 120 may support the door 20 by the door supporter
121 combined with the door frame 21.
[0090] The second bracket 120 may further include a second shaft
hole 122. The second shaft 150 may be coupled to the second shaft
hole 122 to pivotally support the door 20.
[0091] The link unit 130 may include a first coupling hole 131 and
a second coupling hole 132. The first coupling hole 131 may be
formed at one end of the link unit 130 for the first shaft 140 to
be combined therewith. The second coupling hole 132 may be formed
at another end of the link unit 130 for the second shaft 150 to be
combined therewith. The one end of the link unit 130 may be
connected with the first bracket 110 by the first shaft 140, and
the other end of the link unit 130 may be connected with the second
bracket 120 by the second shaft 150.
[0092] The link unit 130 may further include a wire guide 133. The
wire guide 133 may be formed in the link unit 130 for the wire 300
to be arranged along at least a part of the link unit 130. In other
words, the wire guide 133 may be concavely formed along a side of
the link unit 130 for the wire 300 to be inserted thereto.
Specifically, the wire guide 133 may be concavely formed along the
bottom side of the link unit 130.
[0093] The link unit 130 may further include a link unit cover 190.
The link unit cover 190 may be detachably combined with the link
unit 130 for the wire 300 to be arranged between the link unit
cover 190 and the link unit 130. That is, the link unit cover 190
may be detachably combined with the wire guide 133. The link unit
cover 190 may play a role to prevent foreign materials from being
brought into the wire guide 133. Furthermore, the link unit cover
190 may serve to prevent the wire 300 inserted to the wire guide
133 from being exposed to the outside. The link unit cover 190 may
be detachably combined with the wire guide 133 to form a portion of
the exterior of the link unit 130. As such, with the link unit
cover 190 to be detachably combined with the wire guide 133, the
link unit cover 190 may be removed in the process of inserting the
wire 300 to the wire guide 133, thereby improving the working
efficiency, and the link unit cover 190 may be coupled to the wire
guide 133 once the wire 300 is inserted to the wire guide 133,
thereby enabling the wire 300 to be stably received in the wire
receiving space 400.
[0094] The link unit cover 190 may include a recessed part 191. The
recessed part 191 may be formed on a side of the link unit cover
190. Specifically, the recessed part 191 may be formed on a side of
the link unit cover 190 that faces the wire guide 133. The recessed
part 191 may form a wire receiver to receive the wire 300 together
with the wire guide 133 once the link unit cover 190 is coupled to
the wire guide 133. The recessed part 191 may be continuously
formed on a side of the link unit cover 190 that faces the wire
guide 133 to correspond to the wire guide 133.
[0095] The link unit cover 190 may further include couplers 192,
193. The couplers 192, 193 may be formed at an end of the link unit
cover 190. The couplers 192, 193 may be formed on the link unit
cover 190 to extend upwards. The couplers 192,193 may include a
first coupler 192 and a second coupler 193. The first and second
couplers 192 and 193 may face each other with a wire outlet 138
between them. The extents to which the first and second couplers
192 and 193 extend upwards may differ. The first coupler 192 may
face the inner wall of the link unit 130, and the second coupler
193 may face the outer wall of the link unit 130. When the hinge
assembly 100 is installed between the door 20 and the cabinet 10,
the outer wall of the link unit 130 may be directed to the inner
side of the cabinet 10. From another perspective, the outer wall of
the link unit 130 may face the opening 16 or the door glass 22.
When the hinge assembly 100 is installed between the door 20 and
the cabinet 10, the inner wall of the link unit 130 may be directed
to the outer side of the cabinet 10. In the first coupler 192,
there may be a first fixing hole 194 formed to be coupled with a
first fixing protrusion 134 formed on the inner wall of the link
unit 130. In the second coupler 193, there may be a second fixing
hole 195 formed to be coupled with a second fixing protrusion 135
formed on the outer wall of the link unit 130. The link unit cover
190 may be combined with the link unit 130 to cover the wire guide
133 by the couplers 192, 193. Firstly, the second fixing protrusion
135 of the link unit 130 is caught in the second fixing hole 195 of
the second coupler 193, and secondly, the first fixing protrusion
134 of the link unit 130 is fit into the first fixing hole 194 of
the first coupler 192.
[0096] The link unit cover 190 may further include a coupling
protrusion 196. The coupling protrusion 196 enables the link unit
cover 190 to be more stably combined with the link unit 130. The
coupling protrusion 196 may be formed at another end of the link
unit cover 190. The coupling protrusion 196 may be formed at
another end of the link unit cover 190 near a wire inlet 137. The
coupling protrusion 196 may be combined with the coupling hole 136
formed on the inner wall of the link unit 130. Specifically, the
coupling protrusion 196 may be fit into the coupling hole 136.
[0097] The link unit cover 190 may be stably combined with the link
unit 130 by the coupling between the coupling protrusion 196 and
the coupling hole 136, the coupling between the first fixing
protrusion 134 and the first fixing hole 194, and the coupling
between the second fixing protrusion 135 and the second fixing hole
195.
[0098] The link unit 130 may further include the wire inlet 137.
The wire inlet 137 may be formed to be adjacent to the second
bracket 120 in order for the wire 300 passing through the through
hole 23 to be brought into the wire guide 133, i. e., to be
inserted to the wire guide 133. The link unit cover 190 may be
combined with the wire guide 133 such that a portion of the wire
guide 133 adjacent to the second bracket 120 is opened, and the
wire inlet 137 may be formed in the opened portion of the wire
guide 133.
[0099] The link unit 130 may further include the wire outlet 138.
The wire outlet 138 may be formed on a side of the link unit cover
190 near the first bracket 110. The wire outlet 138 may be formed
between the first coupler 192 and the second coupler 193. The wire
300 inserted to the wire guide 133 through the wire inlet 137 may
be pulled out of the wire receiving space 400 through the wire
outlet 138.
[0100] A second bracket installation part 24 may be formed on the
door frame 21 of the door 20 for installation of the second bracket
120. Specifically, the second bracket installation part 24 may be
formed on the back face of the door frame 21 facing the opening
16.
[0101] The hinge assembly 100 may further include a plurality of
shafts 140, 150. The plurality of shafts 140, 150 may include the
first shaft connecting the first bracket 110 and one end of the
link unit 130 and the second shaft 150 connecting the second
bracket 120 and the other end of the link unit 130. The link unit
130 may further include the first coupling hole 131 coupled with
the first shaft 140 and the second coupling hole 132 coupled with
the second shaft 150.
[0102] The door 20 may pivot on the first shaft 140 and the second
shaft 150.
[0103] The door 20 is able to open or close the opening 16 by
pivoting forward and backward from the opening 16 by the link unit
130 that moves horizontally around the first shaft 140 of the hinge
assembly 100.
[0104] The hinge assembly 100 may further include fixing rings 181,
182. The fixing rings 181, 182 may be coupled to at least one of
the first shaft 140 and the second shaft 150 to prevent separation
of the at least of the first shaft 140 and the second shaft 150.
Preferably, the fixing rings 181, 182 may include the first fixing
ring 181 coupled with the first shaft 140 and the second fixing
ring 182 coupled with the second shaft 150.
[0105] The first fixing ring 181 may be coupled to a lower portion
of the first shaft 140 to prevent separation of the first shaft 140
passing a shaft coupling hole 172 of a reinforcing member 170, the
first shaft hole 112 of the first bracket 110, and the first
coupling hole 131 of the link unit 130. Specifically, a stopper 141
formed in the upper portion of the first shaft 140 and the first
fixing ring 181 coupled to a lower portion of the first shaft 140
may prevent the first shaft from being separated from the shaft
coupling hole 172 of the reinforcing member 170, the first shaft
hole 112 of the first bracket 110, and the first coupling hole 131
of the link unit 130.
[0106] The second fixing ring 182 may be coupled to a middle
portion of the second shaft 150 to prevent separation of the second
shaft 150 passing the second shaft hole 122 of the second bracket
120 and the second coupling hole 132 of the link unit 130. The
second fixing ring 182 may be coupled to a middle portion of the
second shaft 150 instead of a lower portion of the second shaft 150
to prevent the wire 300 inserted to the wire inlet 137 from being
damaged by friction with the second fixing ring 182. A stopper 151
formed in the upper portion of the second shaft 150 and the second
fixing ring 182 coupled to a middle portion of the second shaft 150
may prevent the second shaft 150 from being separated from the
second shaft hole 122 of the second bracket 120 and the second
coupling hole 132 of the link unit 130. A coupling position of the
first fixing ring 181 for the first shaft 140 and a coupling
position of the second fixing ring 182 for the second shaft 150 may
not be limited to the above examples but may be variously
changed.
[0107] The hinge assembly 100 may further include an elastic member
160. The elastic member 160 may be provided on the outer side of
the first shaft 140 to enclose the first shaft 140. The elastic
member 160 may be arranged to guide the motion of the link unit 130
by supporting the gap between the first shaft 140 and the link unit
130. The elastic member 160 may include a spring.
[0108] The hinge assembly 100 may further include the reinforcing
member 170. The reinforcing member 170 may be arranged on the first
shaft 140 to support the gap between the cabinet 10 and the hinge
assembly 100.
[0109] The reinforcing member 170 is pivotally coupled to the first
shaft 140 of the hinge assembly 100 at one end, and is supported
and fixed by the rear face 11a of the cabinet 10.
[0110] The reinforcing member 170 may include a body 171, a first
shaft through hole 23 formed at an end of the body 171 for the
first shaft 140 to penetrate, and a fixing part 173 formed at the
other end of the body 171 to be fixed to the cabinet 10.
[0111] A supporting rib 174 may be formed on the outside of the
body 171 to make better contact with the rear face 11a of the
cabinet 10. The supporting rib 174 may reinforce strength of the
reinforcing member 170.
[0112] The fixing part 173 of the reinforcing member 170 may be
formed at an end of the body 171, and may be fixed by a fixing
member 177 such as a bolt passing through a fixing hole 11b formed
on the front frame 11 of the cabinet 10.
[0113] Although an example of the fixing part 173 of the
reinforcing member 170 fixed to the cabinet 10 by the fixing member
177 passing through the fixing hole 11b is illustrated, how to fix
the fixing part 173 is not limited thereto. The fixing part 173 of
the reinforcing member 170 may be fixed in a method such as
screwing, riveting, soldering, cocking, thermosetting, etc.
[0114] The reinforcing member 170 may be provided in the top and
bottom portions of the first shaft 140 as a pair. Separation and
removal of the reinforcing member 170 may be prevented by the
stopper 141 formed in an upper portion of the first shaft 140 and
the first fixing ring 181 coupled in a lower portion of the first
shaft 140.
[0115] The stopper 141 formed on the first shaft 140 may have a
form that protrudes to the outer direction or to the radial
direction of the first shaft 140, and the stopper 151 formed on the
second shaft 150 may have a form that protrudes to the outer
direction or to the radial direction of the second shaft 150.
[0116] The washing machine 1 may further include a protective
member 90 coupled to at least one of the wire inlet 137 and the
wire outlet 138 while enclosing the wire 300 to prevent snapping of
the wire 300. The protective member 90 may have an elastic

least one of rubber and silicon.
[0117] The washing machine 1 may further include the wire receiving
space 400. The wire receiving space 400 may be provided between the
cabinet 10 and the door 20 to receive at least a part of the wire
300. The wire receiving space 400 may be located in the hinge
assembly 100. The recessed part 191 of the link unit cover 190 may
form the wire receiving space 400 together with the wire guide
133.
[0118] FIG. 10 shows wires inserted to a hinge assembly in a
washing machine, according to an embodiment of the present
disclosure, and FIG. 11 shows wires passing a through hole of the
door of a washing machine, according to an embodiment of the
present disclosure. The first bracket 110 is omitted in FIG.
11.
[0119] As shown in FIGS. 10 and 11, the wire 300 may pass the hinge
assembly 100 to connect the first and second electronic parts. The
wire 300 may penetrate the link unit 130 to connect the first and
second electronic parts.
[0120] The wire 300 connected to the second electronic part
equipped in the door 20 at one end is inserted to the hinge
assembly 100 after passing the through hole 23 formed on the rear
side of the door 20. Specifically, the wire 300 passing the through
hole 23 is connected to the first electronic part arranged in the
cabinet 10 through the wire guide 133 formed in the link unit 130.
The wire 300 inserted to the wire guide 133 through the wire inlet
137 is pulled out of the hinge assembly 100 through the wire outlet
138.
[0121] FIG. 12 is an exploded view of a hinge assembly of a washing
machine, according to another embodiment of the present disclosure.
What are overlapped with FIGS. 1 to 11 will be omitted in the
following description.
[0122] As shown in FIG. 12, the wire 300 may be received between
the link unit 130 and link unit cover 190. In other words, the wire
300 may be received in a wire receiving space 900. The recessed
part 191 (see FIG. 7) of the link unit cover 190 may form the wire
receiving space 900 together with one side, preferably, the bottom
side of the link unit 130. The side of the link unit 130 forming
the wire receiving space 900 with the recessed part 191 of the link
unit cover 190 may be a flat plane. In other words, there is no
recess such as the wire guide 133 (see FIG. 8) formed on the side
of the link unit 130 that forms the wire receiving space 900 with
the recessed part 191 of the link unit cover 190. In this case, the
wire 300 received in the wire receiving space 900 may be settled in
the recessed part 191 of the link unit cover 190.
[0123] While a case where the wire 300 passes the link unit 130 of
the hinge assembly 100 in the process of connecting the second
electronic part placed outside the cabinet 10 and the first
electronic part placed inside the cabinet 10 is focused in the
above description, it is also possible for the wire 300 to pass at
least one element of the hinge assembly 100 to connect the first
and second electronic parts.
[0124] Several embodiments have been described above, but a person
of ordinary skill in the art will understand and appreciate that
various modifications can be made without departing the scope of
the present disclosure. Thus, it will be apparent to those ordinary
skilled in the art that the true scope of technical protection is
only defined by the following claims.
