BACKGROUND
[0002] 1. Field
[0003] A laundry treating apparatus is disclosed herein.
[0004] 2. Background
[0005] Typically, laundry treating apparatuses include a dryer to
dry laundry and a washing machine to wash the laundry. The washing
machine uses a detergent to wash laundry, and is generally provided
with a detergent storage device into which the detergent is
introduced.
[0006] Hereinafter, a conventional detergent storage device will be
briefly described with reference to FIG. 1. FIG. 1 shows a
conventional laundry treating apparatus. As shown in FIG. 1, the
conventional laundry treating apparatus 1 may include a cabinet 10
that forms an external appearance of the laundry treating apparatus
1 and provided with a door 12 through which laundry may be
introduced, a tub 20 provided in the cabinet 10 to contain washing
water, a drum 30 rotatably provided in the tub 20 to accommodate
the introduced laundry, a water supply device 40 with valve 44 to
supply washing water into the tub 20, and a drainage device 60 to
discharge the washing water after completion of washing. Such a
laundry treating apparatus may be provided with a detergent storage
device 50 to simultaneously introduce washing water and a detergent
into the tub 20 and the drum 30 to improve the effect of washing of
the laundry by the drum 30.
[0007] The detergent storage device 50 may be provided with a
detergent introduction portion 52 formed in the shape of a drawer
partially withdrawable in a forward direction from the laundry
treating apparatus 1. When detergent is placed in the withdrawn
detergent introduction portion 52 and then the detergent
introduction portion 52 is placed back in the detergent storage
device 50, the detergent may be supplied to the tub 20 and the drum
30 together with washing water, and the laundry may be washed by
the drum 30.
[0008] The detergent storage device 50 may be located at one side
of an upper portion of the laundry treating apparatus 1.
Accordingly, a user must uncomfortably lift the detergent up to the
upper portion of the laundry treating apparatus 1 to introduce the
detergent into the detergent introduction portion 52.
[0009] In recent years, a prop to support a lower surface of the
laundry treating apparatus 1 has sometimes further been provided to
increase a height of a position of a clothing introduction port
(specifically, the door 12). However, adding a prop to the laundry
treating apparatus 1 may further heighten the position of the
detergent introduction portion, thereby increasing user
inconvenience.

schematic views of a detergent supply module according to an
embodiment.
[0020] A laundry treating apparatus 100 according to an embodiment
may be provided with only a first treating apparatus 100a to treat
laundry (such as washing and drying), or may be provided with the
first treating apparatus 100a and a second treating apparatus 100b
arranged at a lower portion of the first treating apparatus 100a to
treat laundry (such as washing and drying), as shown in FIG. 2.
Hereinafter, a description will be given of the laundry treating
apparatus 100 provided with both the first treating apparatus 100a
and the second treating apparatus 100b.
[0021] It is noted that the second treating apparatus 100b may be
arranged at a position other than at the lower portion of the first
treating apparatus 100a. The second treating apparatus 100b may be
a device to wash or dry a small amount of laundry. Alternatively,
the second treating apparatus 100b may simply be an accommodation
space to store laundry or a detergent needed to wash the laundry,
or may be a simple prop to increase a height of the first treating
apparatus 100a.
[0022] The first treating apparatus 100a may include a cabinet 110
that forms an external appearance of the first treating apparatus
100a, a tub 130 provided in the cabinet 110 to contain washing
water, a drum 140 rotatably provided in the tub 130 to accommodate
the laundry, a drive 170 arranged at a back of a tub 130 to rotate
the drum 140, a water supply device 160 to supply washing water to
the tub 130, a drainage device 180 to discharge washing water from
the tub 130, and a detergent supply module 200 to store a detergent
and supply the store detergent to the tub 130.
[0023] As shown in FIG. 3, the cabinet 110 may include a front
panel 112, a back panel (not shown), a side panel 116, and an upper
panel 119. In addition, the cabinet 110 may further include a frame
111 by which the panels may be supported. The frame 111 may not be
visible from the outside due to the panels 112, 116, and 119.
[0024] The frame 111 may be provided with an upper installation
surface 111a to which the front panel 112 may be fixed, and a lower
installation surface 111b to which the detergent supply module 200
may be fixed. The upper installation surface 111a may be positioned
at an upper portion of the frame 111, and the lower installation
surface 111b may be positioned at a lower portion of the frame
111.
[0025] The front panel 112 may be provided with an introduction
port 113 to allow laundry to be introduced into the tub 130
therethrough. The introduction port 113 may be opened and closed by
a door 120. The door 120 may be provided with a control panel 122
for manipulation of the laundry treating apparatus 100.
[0026] The front panel 112 may be inclined in a direction away from
the frame 111. That is, the front panel 112 may be arranged such
that an upper surface of the front panel 112 may be fixed to the
upper installation surface 111a, and a lower surface of the front
panel 112 may be spaced a predetermined distance from the frame
111.
[0027] The front panel 112 may be coupled to the frame 111 such
that a lower space 115 (opening) of an inner space of the first
treating apparatus 100a may be exposed to the outside. The
detergent supply module 200 may be provided in the exposed lower
space of the front panel 112. Accordingly, a front surface of the
first treating apparatus 100a may be defined by the front panel 112
and the detergent supply module 200.
[0028] The side panel 116 may be fastened to both side surfaces of
the frame 111, defining the side surfaces of the first treating
apparatus 100a. The side panel 116 may be formed in the shape of a
rectangular plate. A surface of the side panel 116 that contacts
the front panel 112 may be inclined to support the front panel
112.
[0029] In the case that the side panel 116 is formed in the shape
of a rectangular plate, a support panel 117 to support the front
panel 112 may be further provided between the side panel 116 and
the front panel 112. The support panel 117 may be coupled to both
sides of the front panel 112 to define a space to accommodate the
door 120 and a space (opening 115) to accommodate the detergent
supply module 200.
[0030] The support panel 117 may define a surface that extends
parallel with a surface defined by the side panel 116 and may be
coupled to both side surfaces of the front panel 112.
Alternatively, the support panel 117 and the front panel 112 may be
integrated with one another. In this case, the front panel 112 and
the support panel 117 may be simultaneously coupled to the frame
111 by a reinforcement member 114, thereby simplifying an
assembling process. The reinforcement member 114 may be provided on
or at both side surfaces of the front panel 112 to maintain the
inclination angle of the front panel 112 and to reinforce
attachment of the front panel 112. In this case, the support panel
117 may be fixed to the reinforcement member 114.
[0031] As shown in FIG. 4, the tub 130 may be provided with a tub
introduction port 132 corresponding to the introduction port 113,
and the drum 140 may be provided with a drum introduction port 142
corresponding to the introduction port 113 and the tub introduction
port 132. Accordingly, the user may open the introduction port 113
by opening the door 120 and then introduce laundry into or
withdrawn the same from the drum 140 through the tub introduction
port 132 and the drum introduction port 142.
[0032] A gasket 150 may be provided between the introduction port
113 and the tub introduction port 132. The gasket 150 may not only
prevent transfer of vibration of the tub 130 to the cabinet 110,
but also prevent washing water from leaking from the tub 130.
[0033] To facilitate introduction and withdrawal of the laundry,
the tub 130 and the drum 140 may be arranged to be inclined at a
predetermined angle in the cabinet 110. In this case, the tub
introduction port 132, the drum introduction port 142, and the
introduction port 113 may be arranged to extend parallel with the
inclined surface of the front panel 112. In the case that the
inclined surface of the front panel is perpendicular to the
rotating shaft of the drum, the inclination angle of the tub 130
and the drum 140 with respect to the ground (or a horizontal line)
may be equal to the inclination angle of the front panel 112 with
respect to a line perpendicular to the ground.
[0034] The door 120 may be rotatably provided to, at, or on the
front panel 112 to open and close the introduction port 113, the
tub introduction port 132, and the drum introduction port 142.
[0035] The drive 170 to rotate the drum 140 may be arranged at the
back of the tub 130. The drive 170 may be provided with a stator
fixed to a rear surface of the tub 130, a rotor arranged to
surround the stator, and a rotating shaft arranged to penetrate the
back of the tub 130 to connect the drum 140 with the rotor.
[0036] A detergent storage module 190 to store the detergent and to
supply the stored detergent to the tub 130 when the water supply
device 160 supplies washing water may be further provided in the
cabinet 110. The detergent storage module 190 may be provided with
a storage body 194 arranged at an upper portion of the introduction
port 132 to store the detergent, and a tub supply conduit 196 that
allows the storage body 194 to communicate with the tub 130
therethrough. In this case, the water supply device 160 may be
provided with a water supply channel 162 to connect a water supply
source located outside of the laundry treating apparatus 100 with
the storage body 194, and a water supply valve 164 to open and
close the water supply channel 162.
[0037] The detergent storage module 190 may be formed in the shape
of a drawer that allows the storage body 194 to be withdrawable
from the cabinet. In this case, the tub supply conduit 196 may need
to be formed of a structure or a material that allows a length of
the tub supply conduit 196 to be varied.
[0038] In the case that the storage body 194 is fixed to an
interior of the cabinet 110 and thus is not withdrawable from the
cabinet, the upper panel 119 may be provided with a door 192 (see
FIG. 3) to open and close the storage body 194.
[0039] The detergent storage module 190 may be distinguished from
the detergent supply module 200 with regard to installation
position and manner of supply of the detergent. That is, the
detergent storage module 190 may be positioned at the upper portion
of the introduction port 113, while the detergent supply module 200
may be positioned at a lower portion of the introduction port 113.
In addition, the detergent storage module 190 may supply the stored
detergent to the tub 130 through the water supply device 160, while
the detergent supply module 200 may supply the stored detergent to
the tub 130 through detergent pumps 211 and 213. Accordingly,
detergent may remain in the detergent storage module 190 for a very
short time, while the detergent supply module 200 may be capable of
storing detergent for a long time. Moreover, the detergent storage
module 190 may allow both liquid detergent and powdered detergent
to be stored therein, while the detergent supply module 200 may
allow only liquid detergent to be stored therein unless a separate
detergent dissolving device is provided.
[0040] The drainage device 180 may serve to discharge the washing
water contained in the tub 130 from the cabinet 110. The drainage
device 180 may be provided with a first drainage channel 181 to
connect the tub 130 with a drainage pump 185, and a second drainage
channel 183 to guide the washing water discharged from the drainage
pump 185 outside of the cabinet 110. The first drainage channel 181
may be provided with a filter 189 to filter the washing water
flowing to the drainage pump 185. To allow the user to easily
remove impurities remaining in the filter 189, the filter 189 may
be detachably provided in the first drainage channel 181. Moreover,
to allow the user to easily replace the filter 189, the filter 189
may be positioned at or in the opening 115 where the detergent
supply module 200 is positioned, a detailed description of which
will be provided hereinbelow.
[0041] As shown in FIGS. 5A-5B, the detergent supply module 200 may
be arranged at or in the opening 115 to store the detergent therein
and to supply the stored detergent to the tub 130 through the
detergent storage module 190. Alternatively, the detergent supply
module 200 may be arranged to directly supply the detergent to the
tub 130.
[0042] The opening 115 may be defined as the space formed by the
support panel 117 provided on or at both side surfaces of the front
panel 112 and a lower surface of the front panel 112. In this case,
a front surface of the first treating apparatus 100a may be formed
by the front panel 112 and the detergent supply module 200. In the
case that the front surface of the cabinet 110 is formed only by
the front panel 112, the opening 115 may be defined as a hole
(provided separately from the introduction port 113) formed at the
lower portion of the introduction port 113 to penetrate the front
panel 112, unlike the view in FIG. 5. That is, the front panel 112
may be provided with a first region having the introduction port
113 and a second region positioned at a lower portion of the first
region and provided with the opening 115. In this case, the door
120 to open and close the introduction port 113 may be rotatably
provided in the first region, and the detergent supply module 200
may be provided in the second region.
[0043] In any of the above cases, the detergent supply module 200
may be arranged at the lower portion of the introduction port 113
to open and close the opening 115. Further, the detergent supply
module 200 may be provided with a module panel 210 coupled to the
lower installation surface 111b of the frame 111, a module door 220
rotatably provided to, at, or in the module panel 210, and a
container 230 provided to the module door 220 to provide a space in
which the detergent may be stored. As the detergent supply module
200 is fixed to the first treating apparatus 100a through coupling
of the module panel 210 to the frame 111, assembly of the detergent
supply module 200 may be simplified.
[0044] The module door 220, which may serve to open and close the
opening 115, may include an accommodation frame 221 coupled to a
hinge 227 of the module panel 210 and adapted to accommodate the
container 230. The hinge 227 may be provided to couple a lower
surface of the module door 220 to the module panel 210, and the
module door 220 may be detachable from the cabinet 110 through a
first fixing portion 223. The first fixing portion 223 may include
with a lock 223a provided to or at one of the module door 220 or
the cabinet 110, and a lock groove 223b provided to or at the other
one of the module door 220 or the cabinet 110 to accommodate the
lock 223a. The lock 223a and the lock groove 223b may be in the
form of a push button.
[0045] The lock 223a and the lock groove 223b may be arranged at
any position on the module door 220 so long as the above functions
are possible. In FIGS. 5A-5B, the lock 223a and the lock groove
223b are arranged at an upper portion of the module door 220 as an
example.
[0046] The module door 220 may further include a second fixing
portion 225 to adjust an angle of rotation of the module door 220.
The second fixing portion 225 may also be arranged at any position
on the module door 220 so long as the above function is possible.
In FIGS. 5A-5B, the second fixing portion 225 is arranged on both
side surfaces of the module door 220, as an example.
[0047] The second fixing portion 225 may be provided with an
extension bar 225a (see FIG. 6) that extends from a side surface of
the module door 220 toward the opening 115, a protrusion 225b that
protrudes from the extension bar 225a, and a stopper 225c provided
to, at, or in the cabinet 110 that allows the protrusion 225b to be
detachably coupled thereto.
[0048] The stopper 225c may be formed to protrude from an inner
circumferential surface of the support panel 117, and the extension
bar 225a and the protrusion 225b may be integrated with one
another. At least one of the extension bar 225a, the protrusion
225b, or the stopper 225c may be formed of an elastically
deformable material. The extension bar 225a may be formed of an
elastically deformable material. When the user pushes the module
door 220 toward the opening 115 such that the module door 220
closes the opening 115 (for example, with the lock 223a coupled to
the lock groove 223b), coupling between the lock 223a and the lock
groove 223b may be released and the module door 220 may rotate away
from the cabinet 110. When the module door 220 rotates away from
the cabinet 110, the extension bar 225a and protrusion 225b of the
second fixing portion may also move away from the cabinet 110. Once
the protrusion 225b is coupled to the stopper 225c, rotation of the
module door 220 may be stopped, and thus, the module door 220 may
maintain a first angle of rotation (a first operation of the module
door). The first angle may be set to an angle at which an upper
surface of the container 230 provided to, at, or in the module door
220 may remain exposed outside of the opening 115 (see FIG. 5A).
When the user pulls the module door 220 away from the cabinet 110
with the first operation of the module door 220 completed, the
module door 220 may perform a second operation (see FIG. 5B). When
the module door 220 is pulled by the user, the extension bar 225a
may be elastically deformed, and thereby coupling between the
protrusion 225b and the stopper 225c may be released. Once coupling
between the protrusion 225b and the stopper 225c is released, the
module door 220 may be rotated by or to a second angle. The second
angle may be set to an angle at which the filter 189 detachably
provided to or in the module panel 210 is exposed. In this case,
the first treating apparatus 100a may be further provided with a
second stopper (not shown) to support the module door 220, such
that the module door 220 may be maintained at the second angle. The
second stopper may be provided to or on the hinge 227 which couples
the module door 220 with the module panel 210, or may be provided
to or on a plate to support the module door 220 on a lower surface
of the cabinet 110. FIG. 5B exemplarily shows the second angle set
to an angle at which the module door 220 extends substantially
parallel to ground.
[0049] Meanwhile, to prevent the module door 220 from abruptly
rotating during the first operation and the second operation, the
first treating apparatus 100a may be further provided with a damper
(not shown). The damper may be a cylinder or an elastic member. In
the case that detergent is contained in the container 230, the
module door 220 may be abruptly rotated due to a weight of the
detergent and the container 230. In this case, there may be a risk
of the container 230 being separated from the module door 220. The
damper serves to address this risk.
[0050] When the module door 220 is rotated to the first angle (by
the first operation), the container 230 may be exposed to the
outside of the first treating apparatus 100a, and accordingly, the
user may check an amount of the detergent stored in the container
230 or a necessity of cleaning of the container. If necessary, the
container 230 may be separated from the first treating apparatus
100a. If the module door 220 is rotated to the second angle (by the
second operation), the filter 189 may be exposed to the outside of
the first treating apparatus 100a, and accordingly, the user may
replace or rinse the filter 189.
[0051] The container 230 provided to, at, or in the module door 220
may be adapted to contain only one kind of detergent.
Alternatively, the container 230 may be adapted to contain two or
more kinds of detergents. That is, as shown in FIG. 6, the
container 230 may be provided with a first container 231 to store a
first detergent, and a second container 233 to store a second
detergent, which may be a detergent of a different kind than the
first detergent, or may be provided with three or more containers.
In this case, the accommodation frame 221 may be provided with a
first accommodation portion 221a to accommodate the first container
231, and a second accommodation portion 221b to accommodate the
second container 233. The first accommodation portion 221a and the
second accommodation portion 221b may be separated from each other
by a partition wall that divides an inner space provided by the
accommodation frame 221.
[0052] The first container 231 and the second container 233 may be
detachably provided to the respective accommodation portions 221a
and 221b. In this case, each of the containers 231 and 233 may be
provided with a detergent discharge conduit 235 to discharge the
detergent stored in the container 231, 233 to the accommodation
portion 221a, 221b.
[0053] That is, a bottom surface 236 of the first container 231 may
be provided with a first detergent discharge conduit 235a to
discharge the detergent stored in the first container 231 to the
first accommodation portion 221a, and a bottom surface of the
second container 233 may be provided with a second detergent
discharge conduit 235b to discharge the detergent stored in the
second container 233 to the second accommodation portion 221b. The
first detergent discharge conduit 235a and the second detergent
discharge conduit 235b may be provided with a structure to
discharge the detergent stored in the container 231, 233 to each of
the accommodation portions 221a and 221b when the containers 231
and 233 are respectively inserted into the accommodation portions
221a and 221b.
[0054] An upper surface 232 of the first container 231 may be
provided with a first detergent introduction port 232a for supply
of the first detergent and a lid 232b to open and close the first
detergent introduction port 232a. The upper surface 234 of the
second container 233 may be provided with a second detergent
introduction port 234a for supply of the second detergent and a lid
234b to open and close the second detergent introduction port
234a.
[0055] At least one of the upper surface 232, 234, and the lid
232b, 234b of each container may be formed of a transparent
material. In the case that the upper surface 232, 234 of each
container is formed of a transparent material, an entire upper
surface need not be formed of the transparent material. That is, at
least one area of the upper surface 232, 234 may be formed of the
transparent material.
[0056] Further, the upper portion of each container 231, 233 may
have a larger cross-sectional area than a lower portion of each
container 231, 233. In addition, each container may be formed such
that a cross-sectional area thereof decreases from the upper
surface 232, 234 to the bottom surface 236.
[0057] Accordingly, the user may check an amount of the detergent
stored in each container 231, 233 and a degree of contamination of
an interior of each container through the transparent upper surface
232, 234 or lid 232b, 234b. In addition, as the upper portion of
each container has a greater cross-sectional area than the lower
portion thereof, the user may check an entire interior of each
container 231, 233 at a glance through the transparent upper
surface 232, 234 or lid 232b, 234b, and thus, invisible zones in
the inner space of the container may be eliminated. Further, the
upper surface 232, 234 of each container may be detachably provided
to each container. This allows rinsing of the interior of each
container 231, 233 without separating each accommodation portion
221a, 221b from the corresponding container.
[0058] In the case that a liquid detergent (the first detergent) to
remove contaminants from the laundry is stored in the first
container 231, and a fabric softener (the second detergent) is
stored in the second container 233, a volume of the second
container 233 may be smaller than a volume of the first container
231.
[0059] As consumption of the second detergent may generally be less
than consumption of the first detergent, a volume of the detergent
supply module 200 may be minimized where the filter 189 is coupled
to the module panel 210, such that it is positioned at the lower
portion of the second container 233.
[0060] Detergent pumps 211 and 213 to supply the detergents stored
in the container 230 to the detergent storage module 190 may be
fixed to the module panel 210, to which the module door 220 may be
rotatably coupled. Further, the module panel 210 may be provided
with a filter attaching hole 219 in which the filter 189 may be
detachably accommodated.
[0061] The module panel 210 may have any shape which allows the
module panel 210 to be coupled to the lower installation surface
111b. As the filter attaching hole 219 supports the filter 189 by
penetrating the module panel 210, the user may separate the filter
189 from or couple the same to the drainage device 180 through the
filter attaching hole 219.
[0062] The detergents stored in the respective containers 231 and
233 may be introduced into the detergent pumps 211, 213 through
pump connection conduits 215 and 217. The detergents discharged
from the detergent pumps are guided to the detergent storage module
190 through detergent supply conduits 212 and 214. In the case that
the container includes the first container 231 and the second
container 233, the detergent pumps may include first detergent pump
211, which may communicate with the first container 231, and second
detergent pump 213, which may communicate with the second container
233.
[0063] The first detergent pump 211 may be connected to the first
accommodation portion 221a through the first pump connection
conduit 215, and the second detergent pump 213 may be connected to
the second accommodation portion 221b through the second pump
connection conduit 217. As the containers 231 and 233 are
respectively provided with the detergent discharge conduits 235a
and 235b to discharge the detergents to the accommodation portions
221a and 221b, the detergents discharged from the containers to the
accommodation portions 221a and 221b may be respectively supplied
to the detergent pumps 211 and 213 through the pump connection
conduits 215 and 217.
[0064] The detergent discharge conduits 235a and 235b may be
arranged to directly discharge the detergents to the pump
connection conduits 215 and 217. In this case, the detergent
discharge conduits 235a and 235b may discharge the detergents to
the pump connection conduits 215 and 217 when the containers 231
and 233 are respectively inserted into the accommodation portions
221a and 221b.
[0065] The detergent introduced into the first detergent pump 211
may be supplied to the detergent storage module 190 through the
first detergent supply conduit 212, while the detergent introduced
into the second detergent pump 213 may be supplied to the detergent
storage module 190 through the second detergent supply conduit 214.
Unlike the configuration described above, the first detergent
supply conduit 212 may connect the first detergent pump 211 to the
tub 130, and the second detergent supply conduit 214 may connect
the second detergent pump 213 to the tub 130.
[0066] The module panel 210 may be provided with a connection
conduit hole 218 which the pump connection conduits 215 and 217 may
penetrate. The connection conduit hole 218 may be formed at a lower
end of the module panel 210.
[0067] The detergent pumps 211 and 213 may be fixed to, on, or at a
rear surface of the module panel 210, and the container 230 may be
positioned to, on, or at a front surface of the module panel 210
(in the space between the module panel 210 and the module door
220). Accordingly, the connection conduit hole 218 may serve to
prevent the pump connection conduits 215 and 217 from being
separated from the detergent pumps 211 and 213 when the module door
220 rotates.
[0068] In addition, the pump connection conduits 215 and 217 may be
formed of a flexible material. The pump connection conduits 215 and
217 may be sufficiently long to connect the detergent pumps 211 and
213, respectively, to the accommodation portions 221a and 221b even
when the module door 220 is rotated to the second angle.
[0069] The connection conduit hole 218 may be further provided with
a holder (not shown) to fix the pump connection conduits 215 and
217 to the module panel 210. This may serve to keep lengths of
portions of the pump connection conduits 215 and 217 positioned
between the connection conduit hole 218 and the detergent pumps 211
and 213 constant to prevent tangling of the pump connection
conduits 215 and 217 during rotation of the module door 220.
[0070] FIG. 7 is a schematic view of a detergent supply module
according to another embodiment. In the first treating apparatus
100a provided with the detergent supply module 200, the filter 189
may be separated from the drainage device 180 only when the module
door 220 is opened. FIG. 7 illustrates a case in which the filter
189 is separable from the drainage device 180 without opening the
module door 220.
[0071] The detergent supply module 200 of FIG. 7 may further
include a communication hole 228 formed to penetrate the module
door 220 and arranged at a position corresponding to that of the
filter 189, and a communication hole lid 229 to open and close the
communication hole 228. To minimize a volume of the detergent
supply module 200, the filter 189 may be positioned at the lower
portion of the second container 233. The communication hole 228 may
be arranged to penetrate the module door 220 positioned at the
lower portion of the second container 233.
[0072] In this embodiment, the filter 189 may be exposed through
the communication hole 228 when the communication hole lid 229 is
separated from the module door 220. Accordingly, the user may
separate the filter 189 from the drainage device 180 without
opening the module door 220.
[0073] While the container 230 is illustrated as being detachably
provided to, at, or on the module door 220, the container 230 may
be detachably provided to, at, or on the module panel 210 or the
cabinet 110. In the case that the container 230 is detachably
provided to, at, or on the module panel 210, the accommodation
frame 221 may be provided to, at, or on the module panel 210.
However, in the case that the container 230 is detachably provided
to, at, or on the cabinet 110, the lower installation surface 111b
of the cabinet 110 may perform the function of the module panel
210, and the module panel 210 may be omitted. That is, the
accommodation frame 221 and the detergent pumps 211 and 213 may be
provided to, at, or on the lower installation surface 111b (or the
cabinet 110), and the filter 189 may be detachably fixed to the
lower installation surface 111b.
[0074] Further, the container 230 may be fixed to one of the module
door 220, the module panel 210, or the cabinet 110. In the case
that the container 230 is fixed to either the module door 220 or
the module panel 210, the accommodation frame 221 may be omitted
and the detergent pumps 211 and 213 may be respectively fixed to
the containers 231 and 233. On the other hand, in the case that the
container 230 is fixed to the cabinet 110, the module panel 210 may
be omitted, and the container 230 may be fixed to the lower
installation surface 111b of the cabinet 110. In this case, the
accommodation frame 221 may be omitted, and the detergent pumps 211
and 213 may be respectively fixed to the containers 231 and
233.
[0075] The detergent pumps 211 and 213 provided to or for the
detergent supply module 200 may have any shape which allows the
detergent pumps 211 and 213 to supply the detergent stored in the
container 230 to the tub 130 or the detergent storage module 190.
That is, the detergent pumps 211 and 213 may move a fluid by
rotation of an impeller, or move the fluid by inducing a change of
cross-sectional area in the detergent supply channel (as in a
peristaltic pump). Alternatively, the detergent pump may move the
fluid by two gears rotating by being engaged with one another.
[0076] In addition, while the first detergent and the second
detergent are illustrated as being supplied to the tub 130 through
the first detergent supply conduit 212 and the second detergent
supply conduit 214, the first detergent supply conduit and the
second detergent supply conduit may be formed as one supply
conduit. In this case, the supply conduit connected to the tub 130
or the detergent storage module 190 may be branched to be connected
to the first detergent pump and the second detergent pump, and a
valve may be provided at the branch point of the supply
conduit.
[0077] Hereinafter, an assembly process of the first treating
apparatus 100a will be described with reference to FIGS. 3 and 8.
FIG. 8 is a flow chart of a process of assembling a detergent
supply module and cabinet according to an embodiment. In the
assembly process of the first treating apparatus 100a, first, the
tub 130, the drum 140, a controller (not shown), and the drive
device 170 may be installed in the frame 111, in step S110.
Thereafter, the side panel 116 may be installed on or at both side
surfaces of the frame 111, in step S120, and the module panel 210
may be fixed to the lower installation surface 111b, in step S130.
Fixing the module panel 210 to the lower installation surface 111b
may be performed with the detergent pumps 211 and 213, the drainage
pump 185, and the drainage filter 189 pre-connected to the module
panel 210 through a separate assembly process.
[0078] After assembly of the module panel 210 is completed, the
front panel 112 may be coupled to the upper installation surface
111a, in step S140. In this case, the upper surface of the front
panel 112 may be coupled to the upper installation surface 11a, and
the lower surface of the front panel 112 may be fixed to the upper
portion of the module panel 210 by a separate fastening means or
fastener (not shown).
[0079] The reinforcement member 114 provided on both side surfaces
of the front panel 112 may be fixed to the frame 111. In this case,
the front panel 112 may be securely fixed to the frame 111 by the
reinforcement member 114 and the inclination angle of the front
panel 112 may be maintainable.
[0080] After installation of the front panel 112 is completed, the
support panel 117 may be installed, in step S150. The support panel
117 may be fixed to the reinforcement member 114, or to the frame
111. The support panel 117 may close the space defined between the
front panel 112 and the side panel 116.
[0081] After installation of the support panel 117, the upper panel
119 may be installed at the frame 111, in step S160. Installation
of the tub 130, the drum 140, the drive 170, the water supply
device 160, the drainage device 180, and the detergent storage
module 190 in the frame 111 may be completed before installation of
the upper panel 119. In addition, installation of the detergent
supply conduits 212 and 214 provided between the detergent pumps
211 and 213 and the detergent storage module 190 may also be
completed before installation of the upper panel 119.
[0082] Coupling of the module door 220 to the module panel 210, in
step S170, may precede installation of the upper panel 119.
Installing the module door 220, in step S170 may be performed by
coupling the module panel 210 to the module door 220 through the
hinge 227. Thereafter, the door 120 may be installed at the front
panel 112, in step S180, and assembly of the first treating
apparatus may be completed.
[0083] Hereinafter, a process of supply of a detergent by the
detergent supply module 200 will be described with reference to
FIG. 9. FIG. 9 is a schematic view of a flow channel through which
detergent stored in a detergent supply module may be supplied to a
tub.
[0084] When the detergent pumps 211 and 213 operate, the detergents
stored in the containers 231 and 233 may be supplied to the
detergent pumps 211 and 213 through the pump connection conduits
215 and 217, and the detergents supplied to the detergent pumps 211
and 213 may be moved to the storage body 194 provided to, at, or on
the detergent storage module 190 through the detergent supply
conduits 212 and 214. As the storage body 194 communicates with the
tub 130 through the tub supply conduit 196, the detergents moved
from the detergent supply module 200 to the storage body 194 may be
supplied to the tub 130.
[0085] In the above case, the detergents may not be stored in the
detergent storage module 190. The user may supply a separate
detergent to the storage body 194, if necessary. In this case, the
detergent in the storage body 194 may be supplied to the tub 130 by
the washing water supplied through the water supply device 160. The
detergent supplied to the storage body 194 through the detergent
supply module 200 may be supplied regardless of when the washing
water is supplied. The detergent may be supplied to the storage
body 194 before the washing water is supplied or at the same time
as when the washing water is supplied.
[0086] In the case of the first treating apparatus 100a configured
as shown in FIG. 9, the detergent supply conduits 212 and 214 may
become clogged by the detergents. In the structures shown in FIG.
10, clogging of the detergent supply conduits 212 and 214 may be
addressed.
[0087] FIGS. 10A-10D and 11 are schematic views of a laundry
treating apparatus that provides for rinsing of a detergent supply
conduit according to an embodiment. FIG. 10A illustrates a
structure that allows rinsing of the detergent supply conduits 212
and 214 in the case that the detergent storage module 190 is not
provided. In this embodiment, the detergent supply conduits 212 and
214 may be arranged to connect the detergent pumps 211 and 213 to
an upper surface of the tub 130, and the water supply device 160
may supply washing water to the tub 130 through the detergent
supply conduits 212 and 214.
[0088] During the washing operation, the detergent and washing
water may be typically supplied to the tub 130. Accordingly, by
controlling the water supply device 160 and the detergent supply
module 200 to perform supply of the detergent stored in the
detergent storage module 200 upon or after supply of the washing
water to the tub 130, the detergent may be prevented from clogging
the detergent supply conduits 212 and 214.
[0089] FIGS. 10B, 10C and 10D show structures that allow rinsing of
the detergent supply conduits 212 and 214 in the case that the
detergent storage module 190 is provided. In the embodiment shown
in FIG. 10B, the detergent supply conduits 212 and 214 may be
arranged to connect the detergent pumps 211 and 213 with the
storage body 194. In this embodiment, the washing water supplied
from the water supply device 160 may always be supplied to the tub
130 via the detergent supply conduits 212 and 214 and the storage
body 194. Accordingly, it may be possible to supply the detergent
stored in the detergent storage module 190 to the tub 130 and
prevent the detergent from clogging the detergent supply conduits
212 and 214.
[0090] In the embodiment shown in FIG. 10C, the water supply
channel 162 provided to or at the water supply device 160 may
include a first water supply channel 162a to supply washing water
to the storage body 194 and a second water supply channel 162b to
supply washing water to the detergent supply conduits 212 and 214.
The first water supply channel 162a and the second water supply
channel 162b may be branched from one channel 162, and a valve 162c
may be provided at the branch point of each channel.
[0091] The detergent stored in the detergent storage module 190 may
be supplied to the tub 130 by the washing water supplied to the
storage body 194 through the first water supply channel 162a. The
detergent stored in the detergent supply module 200 may be supplied
to the tub 130 through the detergent supply conduits 212 and 214
during operation of the detergent pumps 211 and 213.
[0092] The detergents remaining in the detergent supply conduits
212 and 214 may be discharged to the tub 130 by the washing water
supplied through the second water supply channel 162b. The rinsing
of the detergent supply conduits as discussed above may be
performed every time the detergent pumps 211 and 213 supply the
detergents through the detergent supply conduits 212 and 214, or
may be performed when a number of operations of the detergent pumps
211 and 213 reaches a predetermined reference number.
[0093] In the embodiment shown in FIG. 10D, the detergent supply
conduits 212 and 214 may be arranged to connect the detergent pumps
211 and 213 to the storage body 194. The water supply device 160
may include the first water supply channel 162a to supply washing
water to the storage body 194 and the second water supply channel
162b to supply washing water to the detergent supply conduits 212
and 214. In this embodiment, the first water supply channel 162a
and the second water supply channel 162b may be branched from one
channel 162, and may be provided with a valve 162c at the branch
point. The detergent stored in the detergent storage module 190 may
be supplied to the tub 130 when the first water supply channel 162a
is opened by the valve 162c. The detergent stored in the detergent
supply module 200 may be supplied to the tub 130 through the
detergent supply conduits 212 and 214, the storage body 194, and
the tub supply conduit 196 when the detergent pumps 211 and 213
operate.
[0094] The detergents remaining in the detergent supply conduits
212 and 214 may be discharged to the tub 130 when the washing water
is supplied to the second water supply channel 162b by the valve
162c. Rinsing of the detergent supply conduits may be performed
every time the detergent pumps 211 and 213 operate as discussed
above, or may be performed when a number of operations of the
detergent pumps reaches a predetermined reference number.
[0095] In the first treating apparatus 100a having the structure
shown in FIGS. 10A-10D, the channel 162b (the channel 162 in FIG.
10A) for supply of washing water to the detergent supply conduits
212 and 214 may be arranged to supply the washing water to the
detergent pumps 211 and 213 (to rinse an interior of the detergent
pumps), or may be arranged to supply the washing water to discharge
ports of the detergent pumps.
[0096] The first treating apparatus 100a according to embodiments
may rinse not only the detergent supply conduits 212 and 214, but
also the container 230. In this case, the detergent pumps 211 and
213 may move the washing water toward the detergent supply conduits
212 and 214 or toward the pump connection conduits 215 and 217.
[0097] In the case of the first treating apparatus 100a having the
structure shown in FIG. 9, rinsing of the container 230 may be
performed as the detergent pumps 211 and 213 supply the washing
water introduced into the detergent supply conduits 212 and 214
through the detergent storage module 190 to the container 230. The
washing waster stored in the container 230 may be discharged to the
tub 130 through the detergent supply conduits 212 and 214 by the
detergent pumps 211 and 213.
[0098] The washing water may be discharged from the container 230
to the outside through a branch channel branched from the detergent
supply conduits 212 and 214 to allow the interior of the container
to communicate with the exterior of the cabinet.
[0099] As shown in FIG. 11, the branch channel may be provided with
a first branch conduit 241 that allows the first detergent supply
conduit 212 to communicate with an exterior of the cabinet 110,
that is, the second drainage channel 183, therethrough, and a
second branch conduit 245 that allows the second detergent supply
conduit 214 to communicate with the exterior of the cabinet 110.
The first branch conduit 241 may be provided with a first branch
conduit valve 243, and the second branch conduit 245 may be
provided with a second branch conduit valve 247. The first branch
conduit valve 243 and the second branch conduit valve 247 may close
the branch conduits 241 and 245 when the detergent in the container
is supplied to the detergent storage module 190 or the tub 130, and
open the branch conduits 241 and 245 only when the container is
rinsed.
[0100] In this embodiment, the rinsing water may be supplied to the
detergent pumps 211 and 213 through the detergent storage module
190 and the detergent supply conduits 212 and 214. Alternatively,
rinsing water may be directly supplied to the detergent pumps 211
and 213 from the water supply source. That is, a separate channel
for supply of rinsing water may be further provided between the
water supply source and the detergent pumps 211 and 213.
[0101] In the case of the first treating apparatus 100a having the
structure shown in FIGS. 10A-10D, rinsing of the container 230 may
be performed through supply of the washing water supplied to the
detergent supply conduits 212 and 214 through the water supply
device 160 to the container 230 through the pump connection
conduits 215 and 217 by the detergent pumps 211 and 213, and
