heated air, and into which air that has passed through the inside of the drum 30 is
re-introduced.
[0108] Referring to FIG. 4, the heater 50 may include an air passage 51 in communication
with the inside of the drum 30. Air containing water vapor generated by evaporation
of moisture present in the laundry may exist inside the drum 30, and air inside the
drum 30 may be discharged from the drum 30 and flow into the air passage 51. For example,
air discharged from the inside of the drum 30 to the outside of the drum 30 via the
drum inlet 32 may flow into the air passage 51 and flow along the air passage 51.
[0109] In one example, the heater 50 may include a dehumidifying unit 52. The dehumidifying
unit 52 may come into contact with air flowing along the air passage 51 to condense
water vapor in air and remove water vapor from air. Accordingly, air flowing along
the air passage 51 may be dehumidified such that water vapor is greatly reduced as
it passes through the dehumidifying unit 52.
[0110] The heater 50 may include a temperature increasing unit 53. The temperature increasing
unit 53 may be in direct contact with air flowing along the air passage 51 or may
be in thermal contact with air to heat air. Air flowing along the air passage 51 may
be dried at a high temperature while passing through the dehumidifying unit 52 and
the temperature increasing unit 53.
[0111] The heater 50 may include a fluid system forming the dehumidifying unit 52 and the
temperature increasing unit 53. The fluid system may include a compressor, a condenser,
a diffusion valve, and an expander, the dehumidifying unit 52 may correspond to the
expander, and the temperature increasing unit 53 may correspond to the condenser.
[0112] However, in an embodiment of the present disclosure, the heater 50 is not limited
to including the fluid system, and the dehumidifying unit 52 and the temperature increasing
unit 53 may be in various schemes.
[0113] The heater 50 may include an air fan 54. The air fan 54 may be located in a space
in communication with the air passage 51, for example, on the air passage 51 to generate
a flow of air. By operating the air fan 54, air inside the drum 30 may flow and circulate
through the air passage 51.
[0114] That is, in an embodiment of the present disclosure, the heater 50 dehumidifies and
heats air flowing along the air passage 51 in communication with the inside of the
drum 30 and supplies air back to the inside of the drum 30, thereby providing high-temperature
dry air into the drum 30 and removing moisture contained in the laundry.
[0115] However, the heater 50 in FIG. 4 is only an example of the heater 50 for performing
the drying course. In the present disclosure, a scheme or a type of the heater 50
for providing high-temperature air to the laundry is not necessarily limited as above.
[0116] For example, the heater 50 may be of an exhaust type that allows air from outside
the cabinet 10 to be introduced and flow into the drum 30, and discharges air inside
the drum 30 to the outside. Additionally, the heater 50 may also be of a static type
that heats and dehumidifies air inside the drum 30 while not causing the flow of air.
[0117] In addition, the laundry treating apparatus 1 shown in FIG. 3 and the laundry treating
apparatus 1 shown in FIG. 4 are shown separately for convenience of description, and
it goes without saying that the respective components cannot coexist with each other.
[0118] For example, an embodiment of the present disclosure may include the water supplier
60, the tub 20, the detergent supplier 40, and the like to perform the washing course
of the laundry, and at the same time, include the heater 50 of various types to perform
the drying course of the laundry.
[0119] FIG. 5 schematically shows various communication environments that may be established
by the laundry treating apparatus 1 according to an embodiment of the present disclosure.
[0120] Referring to FIG. 5, the laundry treating apparatus 1 according to an embodiment
of the present disclosure may activate the pairing mode with the at least one external
device 2. For example, the laundry treating apparatus 1 according to an embodiment
of the present disclosure may activate the pairing mode via mutual communication with
the external device 2 disposed outside the cabinet 10.
[0121] That is, the controller 90 may activate the pairing mode via the communication with
the further controller 90 of the external device 2. The controller 90 may activate
the pairing mode while exchanging the information with the further controller 90 or
the further communication unit of the external device 2 via the communication unit.
[0122] FIG. 5 shows a connection to the two external devices 2 according to an embodiment
of the present disclosure, but the number of external devices 2 that may be connected
to the laundry treating apparatus 1 according to an embodiment of the present disclosure
may vary.
[0123] In an embodiment of the present disclosure, the external device 2 may perform the
external treatment course to treat the laundry. For example, the external device 2
may include a drum 30 to accommodate the laundry therein. The external device 2 may
be equipped with the further controller 90 for controlling various devices disposed
in the external device 2, separately from the controller 90 of the laundry treating
apparatus 1 according to an embodiment of the present disclosure.
[0124] Additionally, the external device 2 may include a further output device 130 that
outputs a screen to provide information related to an operation situation, a laundry
treatment state, or the like controlled by the further controller 90.
[0125] The laundry treating apparatus 1 according to an embodiment of the present disclosure
may perform the washing course of the laundry, and the external device 2 may perform
the drying course of the laundry.
[0126] The opposite case may also be possible, and both the laundry treating apparatus 1
according to an embodiment of the present disclosure and the external device 2 may
perform the laundry washing course or the drying course.
[0127] In an embodiment of the present disclosure, a communication scheme by which the controller
90 and the external device 2 exchange the information may vary. For example, controller
90 may be in direct communication with the further communication unit of the external
device 2 via the communication unit in a scheme, such as Bluetooth.
[0128] In addition, the controller 90 or the communication unit may be equipped separately
from the laundry treating apparatus 1 according to an embodiment of the present disclosure
and the external device 2, and may exchange the information via an external communication
medium 96 that provides signals for communication.
[0129] For example, the external communication medium 96 may generate a Wi-Fi signal, the
controller 90 may exchange information with the external communication medium 96 based
on the Wi-Fi signal, and the further controller 90, which is disposed in the external
device 2 and is distinct from the controller 90 of the laundry treating apparatus
1 according to an embodiment of the present disclosure, may receive a signal transmitted
from the controller 90 via the information exchange with the external communication
medium 96.
[0130] When the controller 90 directly generates the signal as above and when the external
communication medium 96 is used as the signal generation means, a collection path
of the information transmitted externally from the controller 90 or the information
received by the controller 90 may also vary.
[0131] For example, even when the controller 90 directly transmits or receives the signal,
the controller 90 may directly transmit the signal to the further controller 90 of
the external device 2, or a scheme of transmitting the signal to the external server
97 such that the further controller 90 receives the signal from the server 97 may
be used.
[0132] Even when the controller 90 uses the external communication medium 96, the information
transmitted from the controller 90 to the external communication medium 96 may be
directly transmitted to the external device 2, or the information transmitted to the
external communication medium 96 may be transmitted to the server 97 and then the
further controller 90 of the external device 2 may receive the information from the
server 97.
[0133] In one example, a relationship between a sender and a receiver may be changed between
the controller 90 disposed in the laundry treating apparatus 1 according to an embodiment
of the present disclosure and the further controller 3 of the external device 2.
[0134] In one example, the laundry treating apparatus 1 according to an embodiment of the
present disclosure may also be permitted to be in communication with the user's terminal
95 described above. For example, the controller 90 may provide information related
to the current operating state to the user via the terminal 95, and a remote control
mode controlled based on a command transmitted from the terminal 95 may be activated
via the information exchange with the terminal 95.
[0135] Communication or a scheme of exchanging information between the controller 90 and
the terminal 95 may be the same as the communication or the scheme of exchanging the
information between the controller 90 and the further controller 90 described above.
For example, the controller 90 may exchange the information directly with the terminal
95 or may exchange the information via the external communication medium 96 and/or
the server 97.
[0136] FIG. 6 is a diagram showing an add-on setting screen P500 output from the output
device 130 or the terminal 95 according to an embodiment of the present disclosure.
(a) in FIG. 6 shows the add-on setting screen P500 output from the output device 130,
and (b) in FIG. 6 shows the add-on setting screen P500 output from the terminal 95.
[0137] Referring to FIG. 6, the laundry treating apparatus 1 according to an embodiment
of the present disclosure may support a remote control mode of the user. That is,
the controller 90 may set and perform the treatment course of the laundry by receiving
a command from the user distant from the laundry treating apparatus 1 via the remote
control mode.
[0138] In the remote control mode, the controller 90 may be permitted to be in communication
with the user's terminal 95 or the like, and may receive the command of the user from
the terminal 95 or the like. For example, the user's terminal 95 may be registered
in advance on the laundry treating apparatus 1 and be permitted to be in communication,
and when the remote control mode is applied, the terminal 95 or the like may be in
communication with the controller 90 via the external communication medium 96 or directly
to transmit the input signal generated from the terminal 95 to the controller 90.
[0139] In the remote control mode, the user may select one of the plurality of treatment
courses for treating the laundry, set an option for one treatment course, or control
the controller 90 to perform one treatment course, using the terminal 95 or the like.
[0140] Accordingly, the user may conveniently use the laundry treating apparatus 1 even
when the user is not located adjacent to the laundry treating apparatus 1 according
to an embodiment of the present disclosure.
[0141] In one example, in an embodiment of the present disclosure, the output device 130
and/or the terminal 95 may output a settings list including a remote control setting
item C200 for setting the remote control mode on the screen.
[0142] That is, the output device 130 and/or the terminal 95 may output the add-on setting
screen P500 including the settings list in which the remote control setting item C200
is displayed. The add-on setting screen P500 may be provided such that the user may
select the remote control setting item C200 via the input device 110 or the terminal
95.
[0143] The user may select the remote control setting item C200 on the add-on setting screen
P500 and set the application of the remote control mode, so that the controller 90
may activate the remote control mode.
[0144] In one example, the laundry treating apparatus 1 according to an embodiment of the
present disclosure may activate a remote control maintenance mode in which the remote
control mode is continuously maintained. That is, in an embodiment of the present
disclosure, the controller 90 may activate the remote control maintenance mode to
maintain the remote control mode.
[0145] In an embodiment of the present disclosure, when the remote control maintenance mode
is not applied, the controller 90 may enter the standby state after the treatment
course for treating the laundry is ended.
[0146] As described above, in the standby state, the power consumption may be minimized
by preventing the power from being provided to the remaining power consuming devices
except for the power standby unit. The standby state corresponds to a power-off state
in which the power is not applied from a user's perspective.
[0147] Accordingly, an embodiment of the present disclosure may allow the user to conveniently
use the treatment course of the laundry treating apparatus 1 remotely via the remote
control mode, and further, may prevent unnecessary power consumption as the laundry
treating apparatus 1 that has finished operating automatically enters the standby
state.
[0148] However, the user may, when necessary, request performance of an additional treatment
course after performing the one treatment course. For example, depending on a user's
tendency, the user may request the remote control of the controller 90 even after
the one treatment course has ended, such as wishing to additionally perform the rinsing
course after the washing course or wishing to additionally perform the drying course
after the washing course.
[0149] When maintenance of the remote control mode is required as above, even after the
course performing process in which the treatment course for treating the laundry is
performed via the remote control maintenance mode by the user, the laundry treating
apparatus 1 according to an embodiment of the present disclosure may activate the
remote control mode while maintaining the power-on state.
[0150] FIG. 7 shows an operational flowchart comparing a case in which a remote control
maintenance mode is applied and a case in which the remote control maintenance mode
is released. (a) in FIG. 7 shows a control sequence of the controller 90 or an operation
sequence of the laundry treating apparatus 1 with the remote control maintenance mode
released, and (b) in FIG. 7 shows a control sequence of the controller 90 or an operation
sequence of the laundry treating apparatus 1 with the remote control maintenance mode
applied.
[0151] Referring to FIG. 7, the laundry treating apparatus 1 according to an embodiment
of the present disclosure may maintain the standby state before the use by the user
and may be switched to the power-on state based on the input signal of the user such
as the power button 111.
[0152] In one example, as a general operation sequence, a course selection process in which
the user selects one of the plurality of treatment courses and sets an option may
be performed, and a course performing process in which the laundry treatment is performed
via the treatment course determined in the course selection process.
[0153] In one example, after the course performing process, when the remote control maintenance
mode is released, the operation of the laundry treating apparatus 1 according to an
embodiment of the present disclosure may be ended and the standby state may be entered.
[0154] On the other hand, when the remote control maintenance mode is applied, the power-on
state of the laundry treating apparatus 1 may be maintained, and additional course
selection process and course performing process may be performed based on the input
signal of the user.
[0155] Specifically, the laundry treating apparatus 1 according to an embodiment of the
present disclosure may include the cabinet 10, the drum 30 that is rotatably disposed
inside the cabinet 10 and accommodates the laundry therein, and the controller 90
that is disposed in the cabinet 10 and performs the treatment course of the laundry
accommodated in the drum 30.
[0156] The controller 90 may activate the remote control mode of receiving the command via
the user's terminal 95 and performing the treatment course, and the controller 90
may activate the remote control maintenance mode in which the remote control mode
is maintained in the power-on state even after the treatment course is ended in the
remote control mode.
[0157] FIG. 8 shows a process of applying the remote control mode via the add-on setting
screen P500. Referring to FIG. 8, in an embodiment of the present disclosure, the
remote control mode may be applied or released via the input device 110, which is
disposed on the cabinet 10 and receives the command of the user, or the terminal 95.
[0158] Specifically, in an embodiment of the present disclosure, when the user manipulates
a settings button for setting the add-on, the output device 130 may output the add-on
setting screen P500 as shown in (a) in FIG. 8, and the remote control setting item
C200 may be displayed on the add-on setting screen P500.
[0159] When the user selects the remote control setting item C200 via the manipulation of
the input device 110, the output device 130 may display 'applied' and 'released' items
as setting values for the remote control mode, as shown in (b) in FIG. 8.
[0160] The 'applied' and the 'released' may be changed to other phrases that may express
the application and the release of the remote control mode. (b) in FIG. 8 shows items
named 'on' and 'off'.
[0161] In one example, when the user selects to apply the remote control mode, the output
device 130 may return to the add-on setting screen P500 as shown in (c) in FIG. 8.
However, the output device 130 may return to the add-on setting screen P500, and simultaneously
display a remote control indicator M50 to notify the user that the remote control
mode has been applied on the add-on setting screen P500.
[0162] The remote control indicator M50 may be displayed in a pop-up form on the add-on
setting screen P500, may disappear after being displayed for a preset time or may
disappear based on the input signal of the user, may include a phrase informing the
user of the application of the remote control mode, and may include a phrase informing
the user of features of the remote control mode.
[0163] In one example, when the remote control indicator M50 disappears, the output device
130 may output the add-on setting screen P500 again as shown in (d) in FIG. 8, but
the remote control setting item C200 of the add-on setting screen P500 may display
that the remote control mode is being applied.
[0164] FIG. 8 shows the add-on setting screen P500 output from the output device 130, but
a process of setting the remote control mode via the add-on setting screen P500 using
the terminal 95 is also not much different from the description above.
[0165] FIG. 9 shows the add-on setting screen P500 displaying a remote control maintenance
setting item C220 according to an embodiment of the present disclosure. (a) in FIG.
9 corresponds to the add-on setting screen P500 output from the output device 130,
and (b) in FIG. 9 corresponds to the add-on setting screen P500 output from the terminal
95.
[0166] Referring to FIG. 9, in an embodiment of the present disclosure, the add-on setting
screen P500 may display the remote control maintenance setting item C220 for setting
the remote control maintenance mode. However, the remote control maintenance setting
item C220 may be displayed or activated only when the aforementioned remote control
mode is applied.
[0167] For example, the add-on setting screen P500 output from the output device 130 or
the terminal 95 may display the remote control maintenance setting item C220, and
when the remote control mode is released, entry to the remote control maintenance
setting item C220 may be denied or the remote control maintenance setting item C220
may be treated with low brightness and an input signal for the corresponding item
may be ignored.
[0168] The user may directly select whether to apply or release the remote control maintenance
mode via the manipulation of the remote control maintenance setting item C220. When
the remote control maintenance mode is applied, the power-on state of the laundry
treating apparatus 1 may be maintained even after the course performing process as
described above.
[0169] In the remote control maintenance mode, the controller 90 may maintain the power-on
state indefinitely, but when the input signal of the user is not transmitted even
after a preset time has elapsed, may switch to the standby state or notify the user
that the current state is the power-on state by the remote control maintenance mode.
[0170] FIG. 10 shows the course selection screen P200 and the course performance screen
P300 that may be output from the output device 130. (a) in FIG. 10 corresponds to
the course selection screen P200 on which one of the plurality of treatment courses
may be selected and the option may be set, and (b) in FIG. 10 corresponds to the course
performance screen P300 displaying the process in which the treatment course determined
in the course selection screen P200 is performed.
[0171] The controller 90 may change the treatment course displayed on the course selection
screen P200 based on the input signal of the user via the input device 110 on the
course selection screen P200, or change an option setting value of the treatment course
displayed on the course selection screen P200.
[0172] When the user manipulates the perform button 112 on the course selection screen P200,
the controller 90 may perform the course performing process of performing the treatment
course determined on the course selection screen P200, and the course performance
screen P300 indicating a progress of the treatment course may be output via the output
device 130.
[0173] In an embodiment of the present disclosure, the controller 90 may automatically active
the remote control mode when performing the treatment course. In other words, the
controller 90 may be applied with an automatic remote control function in which the
remote control mode is automatically applied.
[0174] When the automatic remote control function is applied, the controller 90 may automatically
apply the remote control mode via the terminal 95 or the like at the same time as
it enters the course performing process from the course selection process.
[0175] Therefore, after directly manipulating the input device 110 of the cabinet 10 to
perform the course performing process, even without a separate setting process, the
user may pause the course performing process or may restart the course performing
process by changing the treatment course or the option via the terminal 95 or the
like at a point distant from the laundry treating apparatus 1.
[0176] In one example, in an embodiment of the present disclosure, the input device 110
may include a pause button. The pause button may be the same as the perform button
112 described above, or may be distinguished and separated from the perform button
112.
[0177] The controller 90 may release the remote control mode when the pause button is pressed
while performing the treatment course, and maintain the remote control mode when a
pause command is input via the terminal 95.
[0178] With the remote control mode applied, when the pause button of the input device 110
is manipulated, the controller 90 may identify that a current situation is a situation
in which the user is positioned close to the laundry treating apparatus 1 and directly
manipulates the input device 110, and may release the remote control mode.
[0179] In addition, with the remote control mode applied, when the command to pause the
course performing process is input via the terminal 95 rather than via the pause button
of the input device 110, the controller 90 may identify that the user has an intention
to control the laundry treating apparatus 1 via the remote control mode, and may maintain
the remote control mode.
[0180] In one example, as described above, the remote control maintenance mode may be applied
or released via the terminal 95 or the input device 110 disposed on the cabinet 10
and through which the command of the user is input.
[0181] Additionally, in an embodiment of the present disclosure, the controller 90 may set
the remote control maintenance mode to be released when the remote control mode is
executed.
[0182] When the remote control maintenance mode is applied, the power consumption is expected
as the laundry treating apparatus 1 maintains the power-on state even after the course
performing process, and furthermore, it is expect that it is a common situation for
the user to end the laundry treatment by performing the single treatment course. Therefore,
in an embodiment of the present disclosure, the remote control maintenance mode may
be set to be released by default when applying the remote control mode unless separate
settings are made by the user.
[0183] In one example, in an embodiment of the present disclosure, as described above, the
cabinet 10 may include the laundry inlet that is in communication with the inside
of the drum 30, the laundry door 19 that opens and closes the laundry inlet, and the
door lock 17 that maintains the closed state of the laundry door 19.
[0184] Additionally, in the remote control maintenance mode, the controller 90 may maintain
the laundry door 19 in the closed state by controlling the door lock 17 after the
treatment course ends.
[0185] Specifically, when the drum 30, which rotates at a high speed, is exposed to the
outside, safety problems may occur, and therefore, during the course performing process,
the controller 90 may control the door lock 17 to be locked to keep the laundry inlet
18 in the closed state.
[0186] However, when the course performing process ends, because the laundry inside the
drum 30 needs to be taken out by the user, the controller 90 may control the door
lock 17 to be open after the course performing process ends, so that the laundry door
19 may be manipulated by the user and the laundry inlet 18 may be opened.
[0187] In one example, when the remote control maintenance mode is applied, because it is
expected that the additional course performing processes will be performed via the
remote control of the user after the course performing process, the controller 90
may still keep the door lock 17 locked to stably secure a laundry treatment environment
inside the drum 30.
[0188] For example, the controller 90 may control the door lock 17 to be locked in the remote
control maintenance mode, thereby preventing a dangerous situation in which the laundry
door 19 is open during the additional course performing process, and effectively preventing
an abnormal situation in which the laundry is removed from the inside of the drum
30 or other objects are put into the drum 30.
[0189] In one example, in an embodiment of the present disclosure, the input device 110
may include the power button 111 described above, and the remote control maintenance
mode may be released when the power button 111 is pressed after the treatment course
ends.
[0190] Even in the remote control maintenance mode for the user to remotely control the
controller 90 via the terminal 95 or the like, the controller 90 may release the remote
control maintenance mode via the user's manipulation of the input device 110 as needed.
[0191] In one example, a difference between applying and releasing the remote control maintenance
mode after the course performing process may ultimately be seen as a difference between
the standby state and the power-on state for the controller 90 and other power consumption
devices.
[0192] That is, when the remote control maintenance mode is released, the laundry treating
apparatus 1 is scheduled to enter the standby state after the course performing process,
so that the controller 90 may release the remote control maintenance mode based on
the input signal of the power button 111.
[0193] Furthermore, in an embodiment of the present disclosure, the input device 110 may
include a plurality of buttons including the power button 111, and the plurality of
buttons may be deactivated except for the power button 111 in the remote control maintenance
mode after the end of the treatment course.
[0194] That is, in an embodiment of the present disclosure, the controller 90 may maintain
the remote control maintenance mode based on the user's control using the terminal
95 by ignoring manipulation signals of the various buttons included in the input device
110. However, the power button 111 may be activated, and the manipulation of the power
button 111 may be identified as a user's intention to release the remote control maintenance
mode, so that the remote control maintenance mode may be released.
[0195] FIG. 11 shows a screen output from the output device 130 after the end of the course
performing process. Referring to FIG. 11, in an embodiment of the present disclosure,
in the remote control maintenance mode, the output device 130 may output a remote
control maintenance informing screen P520 that informs the user that the remote control
mode is maintained after the end of the treatment course.
[0196] (a) in FIG. 11 shows a course end screen P350, which is output by switching from
the course performance screen P300 when the course performing process ends, and (b)
in FIG. 11 shows the remote control maintenance informing screen P520 output from
the output device 130 after the course end screen P350 is output when the remote control
maintenance mode is applied.
[0197] In an embodiment of the present disclosure, when the power-on state is maintained
in the situation in which the course performing process is ended, the user may suspect
a product failure or experience inconvenience without being aware of the situation
based on the application of the remote control maintenance mode.
[0198] Accordingly, in an embodiment of the present disclosure, the output device 130 may
output the remote control maintenance information screen P520 after the course end
screen P350 such that the user may recognize that the remote control maintenance mode
is being applied.
[0199] In one example, conditions for releasing the remote control maintenance mode may
be displayed on the remote control maintenance informing screen P520. That is, the
remote control maintenance informing screen P520 may include a phrase informing that
the current mode is the remote control maintenance mode and a phrase informing the
release conditions of the remote control maintenance mode.
[0200] As described above, in an embodiment of the present disclosure, the remote control
maintenance mode may be released using the power button 111 of the input device 110.
Additionally, other buttons except for the power button 111 may be deactivated, so
that the input signals may not be generated therefrom or may be ignored.
[0201] That is, in an embodiment of the present disclosure, the release conditions of the
remote control maintenance mode are relatively strict compared to those of other functions
or other modes. Therefore, an embodiment of the present disclosure may guide the release
conditions of the remote control maintenance mode via the input device 110 such that
the user may conveniently release the remote control maintenance mode via the input
device 110.
[0202] However, in an embodiment of the present disclosure, the release conditions of the
remote control maintenance mode may be changed to various schemes, such as using a
button other than the power button 111.
[0203] In one example, the laundry treating apparatus 1 according to an embodiment of the
present disclosure may notify the user via the output device 130 or the terminal 95
that the remote control maintenance mode is being activated when a preset time has
elapsed after the end of the treatment course.
[0204] That is, the controller 90 may identify the elapsed time from the end of the course
performing process to the present, and when the elapsed time exceeds the preset time,

is activated via the output device 130 and/or the terminal 95 to prevent the unnecessary
power consumption.

the controller 90 may output a screen indicating that the remote control maintenance
mode is maintained beyond the preset time via the display 134 of the output device
130, may provide a warning sound via the speaker, and may provide a phrase explaining
the situation in a notification format to the terminal 95.
