8, a supply duct, which supplies the air outside the second cabinet 8 to the second
tub, and a heat exchanger provided in the supply duct to heat the air introduced into
the supply duct.
[0038] In the case in which the second treatment device T is configured only to dry laundry,
on the other hand, the second tub may be omitted from the second treatment device
T. In this case, the second treatment device T additionally requires means for rotatably
supporting the drum. In addition, the second hot air supply unit is configured to
supply hot air to the second drum.
[0039] As shown in FIG. 2, the first laundry treatment device L of the present invention
includes a cabinet 1, a drawer 21, 23, and 25 removably provided in the cabinet 1,
and a laundry accommodation unit 3 and 4 provided in the drawer to provide a laundry
treatment space.
[0040] The cabinet 1 may have an entrance 11, and the drawer 2 may be removed from or inserted
into the cabinet 1 through the entrance 11. The cabinet 1 may have a longer length
in the width direction (X-axis direction) than in the height direction (Y-axis direction)
(i.e. the drawer may have a longer length in the width direction than in the height
direction).
[0041] The drawer includes a drawer body 21 having an open upper surface and a drawer cover
25 provided in the open surface of the drawer body. That is, the drawer body 21 may
have a hollow hexahedral shape, and the drawer cover 25 may be fixed to the drawer
body 21 so as to form the upper surface of the drawer body 21.
[0042] The drawer body 21 may be removed from or inserted into the cabinet 1 via a slider
27. The slider 27 may include a slider body 271, which is fixed to one of the cabinet
1 and the drawer body 21, and a slider housing 273, which is fixed to the other of
the cabinet and the drawer body to define the movement path of the slider body 271.
FIG. 2 shows the case in which the slider housing 273 is fixed to the cabinet 1 and
the slider body 271 is fixed to the drawer body 21 by way of example.
[0043] A drawer panel 23 is provided on the front surface of the drawer body 21. The drawer
panel 23 serves to open and close the entrance 11 in the cabinet.
[0044] As shown in FIG. 1, the drawer panel 23 may be provided with a control panel 231
to control the operation of the first treatment device L. The drawer panel 23 may
include a front panel surface 23a formed so as to be parallel to one surface of the
cabinet having the entrance, a first side surface 23b and a second side surface 23c
extending from opposite side surfaces of the front panel surface toward the cabinet,
and an upper panel surface 23d extending from the upper part of the front panel surface
toward the cabinet. In this case, the control panel 231 may be provided on the upper
panel surface 23d.
[0045] The control panel 231 includes means (a controller of the first treatment device)
for controlling, for example, means (a water supply unit and a drainage unit) for
supplying water to the laundry accommodation unit 3 and 4 and discharging the water
therefrom, means (a driving unit) for rotating laundry, and means (a hot air supply
unit and a moisture supply unit) for supplying steam or hot air to laundry.
[0046] In addition, the control panel 231 may include an input unit (not shown), which allows
a user to input a control command to the first treatment device L, and a display unit
(not shown) (means for displaying information on the operation of the first treatment
device L), which allows the user to check the control command input via the input
unit or which notifies the user of the process of executing the control command input
by the user.
[0047] The drawer cover 25 may be provided with a first cover through-hole 251 and a second
cover through-hole 253, which are formed through the drawer cover 25 for communication
of the inside of the drawer body 21 with the outside.
[0048] The laundry accommodation unit 3 and 4, provided in the drawer 2, may include a tub
3, which is provided in the drawer body 21 to provide the space in which water is
stored, and a drum 4, which is rotatably provided in the tub to store laundry therein.
The tub 3 is fixed inside the drawer 2 via a tub support unit 31.
[0049] The tub 3 is provided in the upper surface thereof with a tub opening 33 for communication
of the inside of the tub 3 with the outside of the tub. The tub opening 33 is opened
and closed by a door 35.
[0050] The door 35 is rotatably provided on the upper surface of the tub 3 (and is configured
to open and close a portion of the upper surface of the tub). The door 35 may be rotated
to the outside of the drawer 2 through the first cover through-hole 251, which is
formed in the drawer cover 25. That is, the door 35 is provided so as to be located
in a region in which the first cover through-hole 251 is projected on the upper surface
of the tub 3. Consequently, the user may introduce laundry into the tub 3 by opening
the door 35 after removing the drawer 2 from the cabinet 1.
[0051] Meanwhile, the tub 3 is provided in the upper surface thereof with an introduction
hole 37, through which water is introduced into the tub 3. The introduction hole 37
is connected to a water supply pipe 511, a description of which will follow.
[0052] The drum 4 may be configured to have a cylindrical shape. The drum 4 may be provided
in the upper surface thereof with a drum opening. In the circumferential surface and
the bottom surface of the drum 4 are provided drum through-holes 41, which are formed
through the drum for communication between the inside of the tub and the inside of
the drum.
[0053] The drum 4 may be rotated in the tub 3 by a driving unit 43 provided outside the
tub 3.
[0054] The driving unit 43 may include a stator 431, which is fixed to the tub 3 and generates
a rotating field, a rotor 433, which is rotated by the rotating field, and a rotary
shaft 435, which extends through the tub 3 to interconnect a drum bottom surface and
the rotor 433.
[0055] As shown in the figure, the rotary shaft 435 may be oriented at a right angle relative
to the tub opening 33 (at a right relative to the ground).
[0056] The reason that the laundry accommodation unit is constituted by the tub 3 and the
drum 4 is to enable the first treatment device L of the present invention to perform
a washing function. In order to enable the first treatment device L to further perform
a laundry-drying function, therefore, a hot air supply unit (not shown) may be further
provided in the cabinet 1 to supply hot air to the tub 3.
[0057] The hot air supply unit (not shown), provided in the first treatment device L, may
include a circulation duct configured to circulate the air in the tub 3 and a heat
exchanger provided in the circulation duct for dehumidification and heating of the
air discharged from the first tub.
[0058] Alternatively, the hot air supply unit (not shown), provided in the first treatment
device, may include a discharge duct, which discharges the air in the tub to the outside
of the cabinet 1, a supply duct, which supplies the air outside the tub to the tub
3, and a heat exchanger, which heats the air introduced into the supply duct.
[0059] In the case in which the first treatment device L is configured only to dry laundry,
on the other hand, the tub 3 may be omitted from the first treatment device L. In
this case, the first treatment device L additionally requires means for rotatably
supporting the drum. In addition, the hot air supply unit is configured to supply
hot air to the drum 4.
[0060] In the case in which the first treatment device L is configured to perform a laundry-washing
function, the first treatment device L further requires a water supply unit 51 and
a drainage unit 54.
[0061] The water supply unit 51 may include a water supply pipe 511, which interconnects
a water source and the introduction hole 37, a water supply hole 37, and a valve 513,
which opens and closes the water supply pipe 511 under the control of the controller
of the first treatment device.
[0062] The water supply pipe 511 extends through the drawer cover 25 via the second cover
through-hole 253. The water supply pipe may have a flexible structure, or may be formed
of an elastic material in consideration of the movement range of the drawer.
[0063] The drainage unit 54 serves to discharge the water stored in the tub 3 to the outside
of the cabinet 1. The drainage unit 54 may include a drainage pipe 541, which guides
the water in the tub 3 to the outside of the cabinet 1, and a pump 543, which is provided
in the drainage pipe 541 to discharge the water from the tub 3. The drainage pipe
may have a flexible structure, or may be formed of an elastic material.
[0064] The first treatment device L having the above structure is configured to have a structure
in which, when the drum 4 is rotated by the driving unit 43, vibration generated in
the drum or the tub is transferred to the drawer 2.
[0065] When the vibration of the drum 4 or the tub 3 is transferred to the drawer 2, noise
or vibration may be generated due to a collision between the drawer 2 and the cabinet
1. Furthermore, the drawer 2 may escape from the cabinet 1 during the rotation of
the drum 4.
[0066] In order to solve the above problems, the laundry treatment apparatus 100 according
to the present invention may further include a fixing unit 6 to detachably fix the
drawer 2 to the cabinet 1.
[0067] As shown in FIG. 3, the fixing unit 6 of the present invention may include a fastening
unit 61, provided at one of the cabinet 1 and the drawer 2, and a detachment unit
65, provided at the other of the cabinet 1 and the drawer 2 such that the fastening
unit is detachably coupled to the detachment unit 65.
[0068] The detachment unit 65 is characterized in that, whenever external force is applied
to the detachment unit 6 via the fastening unit 61, the state in which the detachment
unit 65 is coupled to the fastening unit 61 and the state in which the detachment
unit 65 is separable from the fastening unit 61 are alternately achieved. That is,
the fixing unit 6 of the present invention is characterized in that additional means
(e.g. a handle) for coupling or decoupling between the fastening unit 61 and the detachment
unit 65 is unnecessary.
[0069] The laundry treatment apparatus according to the present invention may be configured
to have a structure in which means, such as a handle, is provided at the drawer panel
23 such that, when a user applies external force to the handle, the fixing unit 6
is operated. However, no means for operating the fixing unit 6 may be provided for
the following reason.
[0070] As shown in FIG. 1, in the case in which the second treatment device T is located
at the upper surface of the first treatment device L, at least a portion of the upper
panel surface 23d is not exposed to the outside by the second cabinet 8 of the second
treatment device T when the drawer body 21 is not removed from the cabinet 1. Consequently,
it is difficult to provide means for operating the fixing unit 6 at the upper panel
surface 23d.
[0071] Meanwhile, means for operating the fixing unit 6 may be provided at the front panel
surface 23a or the first side surface 23b and the second side surface 23c of the panel,
which the user can easily access. In this case, however, the aesthetic appearance
of the laundry treatment apparatus according to the present invention (integrity of
design with the second treatment device) may be deteriorated.
[0072] Consequently, the fixing unit 6 of the present invention may be configured such that
additional means (e.g. a handle) for coupling or decoupling between the fastening
unit 61 and the detachment unit 65 is unnecessary.
[0073] FIG. 3 shows an example of the fixing unit 6, which realizes the above function.
The fastening unit 61 may protrude from the drawer panel 23 toward the entrance 11,
and the detachment unit 65 may be provided at the cabinet 1.
[0074] In this case, the fastening unit 61 may be constituted by a protrusion that protrudes
from the drawer panel 23 toward the entrance 11.
[0075] The detachment unit 65 may include a first body 651 fixed to the cabinet 1 and a
second body 655 provided in the first body 651 so as to perform reciprocating motion,
the fastening unit 61 being detachably coupled to the second body 655.
[0076] The first body 651 includes an insertion hole 652, into which the second body 655
is inserted, a spring 653 to provide elastic force to the second body 655, and a guide
654 to control the position of the second body 655.
[0077] The spring 653 is configured to push the second body 655 toward the insertion hole
652.
[0078] As shown in FIG. 3(b), the guide 654 may include a first path 654a extending from
the direction in which the insertion hole 562 is located toward the rear surface of
the first body 651 (the direction moving away from the insertion hole), a second path
654b extending from one end of the first path toward the insertion hole 562, a third
path 654c extending from the second path in the direction moving away from the insertion
hole 652, and a fourth path 654d extending from the third path 654c toward the insertion
hole 652 so as to be connected to the other end of the first path 654a.
[0079] In this case, the second body 655 may include a bar 655a rotatably coupled to the
second body via a shaft 655b, a protrusion 655c provided on the bar so as to be inserted
into the guide 654, and a first detachment bar 655d and a second detachment bar 655e
rotatably coupled to the second body 655 and exposed outside the first body 651 through
the insertion hole 652.
[0080] In the fixing unit 6 having the above structure, the fastening unit 61 moves the
second body 655 toward the rear surface of the first body 651 when the drawer panel
23 closes the entrance 11.
[0081] When the second body 655 is pushed, the protrusion 655c is located at the connection
(first point) between the second path 654b and the third path 654c via the first path
654a and the second path 654b, and the first detachment bar 655d and the second detachment
bar 655e are rotated toward the fastening unit 61 while being interfered with by the
insertion hole 652.
[0082] When the protrusion 655c, provided on the second body, is located at the first point,
as shown in FIG. 3(b), the fastening unit 61 is fixed between the detachment bars
655d and 655e, whereby the drawer 2 is fixed to the cabinet 2. Consequently, it is
possible to prevent the drawer from escaping from the cabinet during the rotation
of the drum.
[0083] Meanwhile, when the user pushes the drawer panel 23 in the direction in which the
entrance 11 is located one more time in this state, the fastening unit 61 pushes the
second body 655. In this case, the protrusion 655c moves to the connection (second
point) between the fourth path 654d and the first path 654a via the third path 654c
and the fourth path 654d.
[0084] When the protrusion 655c, provided on the second body, is located at the second point,
as shown in FIG. 3(a), the first detachment bar 655d and the second detachment bar
655e move to the outside of the first body 651 through the insertion hole 652, whereby
the fastening unit 61 becomes separable from the second body 655. Consequently, the
state in which the drawer 2 is fixed to the cabinet 1 is released, and therefore the
user may remove the drawer to the outside of the cabinet 1.
[0085] In the above description, the fixing unit 6 is configured such that the fastening
unit 61 is fixed to the drawer panel 23 while the detachment unit 65 is fixed to the
cabinet 1. However, the positions of the fastening unit 61 and the detachment unit
65 may be changed.
[0086] That is, the fastening unit 61 may be fixed to the rear surface of the drawer body
21, and the detachment unit 65 may be fixed to the rear surface of the cabinet 1 such
that the fastening unit 61 is detachably fixed to the detachment unit 65.
[0087] In addition, the fastening unit 61 may be fixed to at least one of the opposite side
surfaces of the drawer body 21, and the detachment unit 65 may be fixed to at least
one of the opposite side surfaces of the cabinet 1 such that the fastening unit 61
is detachably fixed to the detachment unit 65.
[0088] Meanwhile, in the laundry treatment apparatus 100 having the above structure, the
drawer 21 may be removed from the cabinet 1 only when the user pulls the drawer panel
23. Consequently, the first treatment device L requires means for enabling the user
to hold the drawer panel 23, such as a handle.
[0089] In the laundry treatment apparatus 100 configured such that the second treatment
device T is located on the first treatment device L, however, the upper surface of
the drawer panel 23 may not be exposed to the outside due to the second treatment
device T. For this reason, the handle may be provided at the side surface or the front
surface of the drawer panel. In the case in which the handle is provided at the front
surface or the side surface of the drawer panel, however, the costs of manufacturing
the laundry treatment apparatus are increased, and the aesthetic appearance of the
laundry treatment apparatus may be deteriorated.
[0090] In order to solve the above problems, a pushing unit 7 for pushing the drawer body
31 toward the entrance 11 may be further provided. That is, the pushing unit 7 may
be configured to push the drawer panel 23 in the direction moving away from the entrance
11.
[0091] As shown in FIG. 4, the pushing unit 7 may include a cylinder 71 fixed to the cabinet
1, a pushing body 73 having a first free end F1 configured to perform reciprocating
motion in the cylinder 71 and a second free end F2 configured to contact the drawer
panel 23 when the drawer panel 23 closes the entrance 11, and a spring 75 provided
in the cylinder 71 to support the first free end F1.
[0092] The spring 75 may be configured to provide force necessary to move the second free
end F2 in the direction in which the entrance 11 is located to the first free end
F1. In order to prevent damage to the drawer panel 23, a damper 77, such as rubber,
may be further provided at the second free end F2 of the pushing body.
[0093] Unlike the above description, the pushing unit 7 may be configured to push at least
one of the rear surface of the drawer body 21 or the side surface of the drawer body
21 toward the entrance 11.
[0094] Hereinafter, the operation of the first treatment device L of the present invention
will be described with reference to FIGs. 2 and 5.
[0095] When the user pushes the drawer panel 23 toward the entrance 11 in the state in which
the drawer body 21 is fixed to the cabinet 1, as shown in FIG. 2, the fastening unit
61, provided at the drawer panel 23, is separated from the detachment unit 65, provided
at the cabinet 1.
[0096] When the fastening unit 61 is separated from the detachment unit 65, the pushing
unit 7 pushes the drawer panel 23 in the direction moving away from the entrance 11,
whereby a predetermined space is formed between the drawer panel 23 and the entrance
11 in the cabinet.
[0097] The user may put his/her hand into the space formed between the drawer panel 23 and
the entrance 11 in order to hold the upper surface of the drawer panel 23, and may
pull the drawer panel 23 in order to remove the drawer body 21 from the cabinet 1.
In the present invention, therefore, it is possible to remove the drawer body 21 from
the cabinet without the provision of an additional handle at the drawer panel 23.
[0098] Meanwhile, in the case in which the drawer body 21 is removed from the cabinet 1,
as shown in FIG. 5, the user may push the drawer panel 23 toward the entrance 11 in
order to couple the fastening unit 61 to the detachment unit 65. As a result, the
drawer body 21 is fixed to the cabinet 1. Consequently, it is possible to prevent
the drawer body 23 from escaping from the cabinet 1 even though vibration is generated
in the drawer 3 when the drum 4 is rotated by the driving unit.
[0099] Although not shown in the drawings, the fixing unit 6 and the pushing unit 7 may
be provided at the slider 27.
[0100] In this case, the fastening unit 61 may be provided at one of the slider body 271
and the housing 273, and the detachment unit 65 may be provided at the other of the
slider body 271 and the housing 273. In addition, the pushing unit 7 may be provided
at the slider 27 so as to provide force necessary to move the drawer panel 23 in the
direction in which the entrance is opened.
[0101] In the case in which the slider body 271 is fixed to the drawer 2 and the housing
273 is fixed to the cabinet 1, as shown in FIG. 5, the pushing unit 7 may be fixed
to the housing 273 in order to provide force necessary to move the drawer toward the
entrance to the slider body 271.
[0102] It will be apparent to those skilled in the art that various modifications and variations
can be made in the present invention without departing from the spirit or scope of
the invention. Thus, it is intended that the present invention cover the modifications
