Technical Field

The present disclosure relates to a washing machine having a plurality of washing devices.

Background

Generally, a washing machine includes a washing device (washing tub), and is a device for removing contaminants from laundry using water and detergent. The washing machine performs washing of laundry through a series of operations such as a washing course, a rinsing course, and a dehydrating course using a motor as a main power. In the modern times, the washing machine is configured to have a drying function so that the washing machine can also perform a drying process of drying the dehydrated laundry.

When washing, the washing machine may not be able to simultaneously wash a plurality of laundry accommodated in one washing device according to the type or material of the laundry. Since the conventional washing machine has one washing device, a user must directly classify a plurality of laundry into various types of laundry before the washing machine is operated, and select only some laundry that cannot be simultaneously washed in one washing machine from among all the laundry.

In this case, the user may feel inconvenience because the user must select some laundry to be washed in a separate washing course from among the entire laundry and the washing machine must be driven several times (e.g., twice), thereby causing waste of energy and time. In addition, although a user desires to wash a small amount of laundry using the washing machine, unnecessary power consumption occurs if the drum of the washing machine is a large-capacity drum.

Fig. 4 is a flowchart illustrating an integrated power mode control algorithm of a washing machine according to an embodiment of the present disclosure, fig. 5 is a view illustrating a state in which control panels of a plurality of washing devices are turned off as an integrated power in the washing machine according to an embodiment of the present disclosure, fig. 6 is a view illustrating a state in which control panels of a plurality of washing devices are turned on as an integrated power in the washing machine according to an embodiment of the present disclosure, and fig. 7 is a view illustrating a state in which a washing cancel button is activated at a right side of the control panel in the washing machine according to an embodiment of the present disclosure.

Referring to fig. 4, the user may turn on a power button 403-1(700) of the third user interface 403 provided on the control panel 50.

When the power button 403-1 is turned on, the first washing device 100 and the second washing device 200 are simultaneously turned on while the user interface 400, which has been turned off as shown in fig. 5, is turned on as shown in fig. 6.

In a state where the power of the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 may determine whether the power of the first washing device 100 is turned on (802).

When the power of the first washing device 100 is turned on, the first washing device 100 may enter an operation ready state (804).

When the first washing device 100 enters the operation ready state, the user may select a washing course and options of the first washing device 100 using the first user interface 401 (806). The wash course may include a standard course, a gentle course, a wool course, a towel course, a bedding course, etc., and the options may include wash water temperature, rinsing times, dehydration strength, etc.

Subsequently, the controller 500 may determine whether the selection of the wash course and option of the first washing device 100 is completed (808).

As a result of the determination of operation 808, when the selection of the washing course and option of the first washing device 100 is not completed, the controller 500 may return to operation 806 for a subsequent operation.

In operation 808, when the selection of the washing course and option of the first washing device 100 is completed, the user may select the first start button 403-2(810) of the first washing device 100.

When the first start button 403-2 is selected, the first washing device 100 may start an operation according to the selected wash course and option and perform a washing course, a rinsing course, and a dehydrating course (812).

When the operation of the first washing device 100 is initiated, as shown in fig. 7, the first and second washing cancel buttons 404 and 405 may be activated in the user interface 400.

As such, when the user selects the first washing cancellation button 404 of the first washing device 100 while the washing, rinsing, and spinning processes of the first washing device 100 are performed, the controller 500 may determine whether the first washing cancellation button 404 is selected (814).

As a result of the determination of operation 814, when the first washing cancel button 404 is not selected, the controller 500 may return to operation 812 to continue the process of the first washing device 100.

In operation 814, when the first wash cancel button 404 is selected, the controller 500 may cancel the process of the first washing device 100 (816).

Subsequently, the controller 500 may count the time at which the course of the first washing device 100 is canceled by using the built-in timer 503, and determine whether the counted time has elapsed a predetermined time (N minutes; about 3 minutes as a reference time for determining whether the course of the first washing device is canceled) (818). This is to determine whether a predetermined time (about 3 minutes) has elapsed since the first wash cancel button 404 was selected, because the user may erroneously press the first wash cancel button 404.

As a result of the determination of operation 818, when a predetermined time (N minutes) elapses while the process of the first washing device 100 is canceled, the controller 500 may determine that the predetermined time elapses after the first washing cancel button 404 is selected.

Accordingly, after a predetermined time elapses after the first washing cancel button 404 is selected, the controller 500 may turn off the power of the first washing device 100 (820) and terminate the operation.

Meanwhile, in a state where the power of the first and second washing devices 100 and 200 is simultaneously turned on due to the power button 403-1 being turned on in the operation 700, the controller 500 may determine whether the power of the second washing device 200 is turned on (902).

When the power of the second washing device 200 is turned on, the second washing device 200 may enter an operation ready state (904).

When the second washing device 200 enters the operation ready state, the user may select a washing course and options of the second washing device 200 using the second user interface 402 (906). Subsequently, the controller 500 may determine whether the washing course and selection of the option of the second washing device 200 are completed (908).

As a result of the determination of operation 908, when the selection of the washing course and option of the second washing device 200 is not completed, the controller 500 may return to operation 906 for a subsequent operation.

In operation 908, when the selection of the wash course and option of the second washing device 200 is completed, the user may select the second start button 403-3(910) of the second washing device 200.

When the second start button 403-3 is selected, the second washing device 200 may start an operation according to the selected wash course and option and perform a washing course, a rinsing course, and a dehydrating course (912).

When the operation of the second washing device 200 is initiated, as shown in fig. 9, the first and second washing cancel buttons 404 and 405 may be activated in the user interface 400.

As such, when the user selects the second washing cancellation button 405 of the second washing device 200 while the washing, rinsing, and spinning processes of the second washing device 200 are performed, the controller 500 may determine whether the second washing cancellation button 405 is selected (914).

As a result of the determination of operation 914, when the second washing cancel button 405 is not selected, the controller 500 may return to operation 912 to continue the process of the second washing device 200.

In operation 914, when the second washing cancel button 405 is selected, the controller 500 may cancel the process of the second washing device 200 (916).

Subsequently, the controller 500 may count the time at which the course of the second washing device 200 is canceled by using the built-in timer 503, and determine whether the counted time has elapsed a predetermined time (N minutes; about 3 minutes as a reference time for determining whether the course of the second washing device is canceled) (918). This is to determine whether a predetermined time (about 3 minutes) has elapsed since the second wash cancel button 405 was selected, because the user may erroneously press the second wash cancel button 405.

As a result of the determination of operation 918, when a predetermined time (N minutes) elapses while the process of the second washing device 200 is canceled, the controller 500 may determine that the predetermined time elapses after the second washing cancel button 405 is selected.

Accordingly, after a predetermined time elapses after the second washing cancel button 405 is selected, the controller 500 may turn off the power of the second washing device 200 (920) and terminate the operation.

On the other hand, when the user turns off the power button 403-1 during the processes (the washing process, the rinsing process, and the dehydrating process) of the first and second washing devices 100 and 200 in operations 812 and 912, the controller 500 may determine whether the power button 403-1 is turned off (702).

As a result of the determination of operation 702, when the power button 403-1 is not turned off, the controller 500 may return to operations 812 and 912 to continue the processes of the first and second washing devices 100 and 200.

On the other hand, as the determination result of operation 702, when the power button 403-1 is turned off, the controller 500 may perform operations 816 and 916 to cancel the processes of the first and second washing devices 100 and 200 and perform subsequent operations.

As such, the washing machine 1 according to an embodiment of the present disclosure may simultaneously turn on or off the power of the first and second washing devices 100 and 200 using the power button 403-1 provided on the control panel 50. That is, one power button 403-1 may perform the function of an integrated power supply. Next, a process of entering the sleep mode when a predetermined time elapses without a button input to the first user interface 401 or the second user interface 402 will be described with reference to fig. 8.

Fig. 8 is a flowchart illustrating a sleep mode control algorithm of a washing machine according to an embodiment of the present disclosure.

Referring to fig. 8, the user may turn on a power button 403-1(1000) of the user interface 400 provided in the control panel 50.

When the power button 403-1 is turned on, the first washing device 100 and the second washing device 200 are simultaneously turned on while the turned-off user interface 400 is turned on (see fig. 5 and 6).

In a state where the power of the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 may determine whether the power of the first washing device 100 is turned on (1102).

When the power of the first washing device 100 is turned on, the first washing device 100 may enter an active mode as an operation ready state (1104).

When the first washing device 100 enters the operation ready state, the user may input buttons for selecting a washing course and options of the first washing device 100 using the user interface 400.

Accordingly, the controller 500 may determine whether there is a button input of the first user interface 401 corresponding to the first washing device 100 (1106).

As a result of the determination of operation 1106, when there is a button input of the first user interface 401, the first washing device 100 may perform a subsequent operation while maintaining the activation mode as an operation ready state.

Meanwhile, in operation 1106, when there is no button input of the first user interface 401, the first washing device 100 may enter a sleep mode (1110). The time to enter the sleep mode may be when no button input of the first user interface 401 corresponding to the first washing device 100 is continued for a predetermined time (N minutes), and the time to enter the sleep mode is not limited thereto.

When the first washing device 100 enters the sleep mode, the first user interface 401 corresponding to the first washing device 100 is turned off. When the first user interface 401 is turned off, this means that the screen of the first user interface 401 displays an operation screen in which all illumination except the LED lamp of the first start button 403-2 is slowly dimmed and turned off.

As described above, in a state where the first washing device 100 enters the sleep mode, the controller 500 may determine whether there is a button input of the first user interface 401 corresponding to the first washing device 100 (1112).

As a result of the determination of operation 1112, when there is no button input of the first user interface 401, the first washing device 100 may return to operation 1110 and perform a subsequent operation while maintaining the sleep mode.

Meanwhile, in operation 1112, when there is a button input of the first user interface 401, the first washing device 100 may perform operation 1108 to re-enter the activation mode as the operation ready state.

Meanwhile, in a state where the power of the first washing device 100 and the second washing device 200 are simultaneously turned on due to the power button 403-1 being turned on in the operation 1000, the controller 500 may determine whether the power of the second washing device 200 is turned on (1122).

When the power of the second washing device 200 is turned on, the second washing device 200 may enter an operation ready state (1124).

When the second washing device 200 enters the operation ready state, the user may input buttons for selecting a washing course and options of the second washing device 200 using the user interface 400.

Accordingly, the controller 500 may determine if there is a button input of the second user interface 402 corresponding to the second washing device 200 (1126).

As a result of the determination of the operation 1126, when there is a button input of the second user interface 402, the second washing device 200 may perform a subsequent operation while maintaining the activation mode as an operation ready state.

Meanwhile, in operation 1126, when there is no button input of the second user interface 402, the second washing device 200 may enter the sleep mode (1130). The time to enter the sleep mode may be when no button input of the second user interface 402 corresponding to the second washing device 200 is continued for a predetermined time (N minutes), and the time to enter the sleep mode is not limited thereto.

When the second washing device 200 enters the sleep mode, the second user interface 402 corresponding to the second washing device 200 is turned off. When the second user interface 402 is turned off, this means that the screen of the second user interface 402 displays an operation screen in which all illumination except the LED lamp of the second start button 403-3 is slowly dimmed and turned off. As described above, in a state where the second washing device 200 enters the sleep mode, the controller 500 may determine whether there is a button input of the second user interface 402 corresponding to the second washing device 200 (1132).

As a result of the determination of operation 1132, when there is no button input of the second user interface 402, the second washing device 200 may return to operation 1130 and perform a subsequent operation while maintaining the sleep mode.

Meanwhile, in operation 1132, when there is a button input of the second user interface 402, the second washing device 200 may perform operation 1128 to re-enter the activation mode as an operation-ready state.

Next, when the first washing device 100 or the second washing device 200 enters the sleep mode after a predetermined time without a button input, the first washing device 100 or the second washing device 200 may provide various display screens of the sleep mode.

For example, in case that the second washing device 200 enters the sleep mode among the first and second washing devices 100 and 200, after entering the sleep mode, the second washing device 200 may display a screen providing the phrase "wake-on-touch" on an upper portion of the second user interface 402 corresponding to the second washing device 200.

In addition, in case that the second washing device 200 enters the sleep mode among the first and second washing devices 100 and 200, after entering the sleep mode, the second washing device 200 may display a screen on which the LED lamp of the second actuating button 403-3 corresponding to the second washing device 200 is slowly and repeatedly turned on and then turned off.

In case that the second washing device 200 enters the sleep mode among the first and second washing devices 100 and 200, after entering the sleep mode, the second washing device 200 may display a screen providing the phrase "sleep" on the 7 th segment 18:88 of the second user interface 402 corresponding to the second washing device 200.

Further, in case that the second washing device 200 enters the sleep mode among the first and second washing devices 100 and 200, after entering the sleep mode, the second washing device 200 may display a screen for notifying the entering of the sleep mode as an icon on an upper portion of the second user interface 402 corresponding to the second washing device 200.

Next, in a state in which the first or second washing device 100 or 200 enters the sleep mode after a predetermined time without a button input, the first or second washing device 100 or 200 may provide various display screens for releasing the sleep mode by waking up.

For example, in case that the sleep mode of the second washing device 200 is released among the first and second washing devices 100 and 200, the second washing device 200 may display a screen for releasing the sleep mode by touching a "wake-on-touch" provided on an upper portion of the user interface 402 corresponding to the second washing device 200 in the sleep mode of the second washing device 200.

In this case, the sleep mode may be released by selecting any button of the second user interface 402 corresponding to the second washing device 200, but is not limited thereto.

In addition, in case that the sleep mode of the second washing device 200 is released among the first and second washing devices 100 and 200, when the user performs a wake-up in the sleep mode of the second washing device 200, the second washing device 200 may display an operation screen in which illumination is sequentially turned on from the center of the second user interface 402 to both sides.

In addition, in case that the sleep mode of the second washing device 200 is released among the first and second washing devices 100 and 200, when the user wakes up the sleep mode of the second washing device 200, the second washing device 200 may display an operation screen in which illumination is sequentially turned on from the left side to the right side of the second user interface 402.

In case that the sleep mode of the second washing device 200 is released among the first and second washing devices 100 and 200, when the user wakes up the sleep mode of the second washing device 200, the second washing device 200 may display an operation screen in which illumination is sequentially turned on to the left and right from a position where the second user interface 402 is touched.

In addition, in case that the sleep mode of the second washing device 200 is released among the first and second washing devices 100 and 200, when the user wakes up the sleep mode of the second washing device 200, the second washing device 200 may display an operation screen in which the overall illumination is slowly brightened.

Next, a procedure of switching the first user interface 401 or the second user interface 402 to the active mode by opening the first door 160 or the second door 260 when operating in the sleep mode after a predetermined time has elapsed without a button input to the first user interface 401 or the second user interface 402 will be described with reference to fig. 9.

Fig. 9 is a flowchart illustrating an active mode switching control algorithm of a washing machine according to an embodiment of the present disclosure.

Referring to fig. 9, the user turns on a power button 403-1(1200) of the user interface 400 provided on the control panel 50.

When the power button 403-1 is turned on, the first washing device 100 and the second washing device 200 are simultaneously turned on while the turned-off user interface 400 is turned on (see fig. 5 and 6).

In a state where the power of the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 may determine whether the power of the first washing device 100 is turned on (1202).

When the power of the first washing device 100 is turned on, the first washing device 100 may enter an operation ready state (1204).

When the first washing device 100 enters the operation ready state, the user may input buttons for selecting a washing course and options of the first washing device 100 using the first user interface 401.

Accordingly, the controller 500 may determine whether there is a button input corresponding to the first washing device 100 (1206).

As a result of the determination of operation 1206, when the button is input, the first washing device 100 may perform a subsequent operation while maintaining the operation ready state.

Meanwhile, in operation 1206, when there is no button input of the first user interface 401, the first washing device 100 may enter the sleep mode (1210). The time to enter the sleep mode may be when no button input of the first user interface 401 corresponding to the first washing device 100 is continued for a predetermined time (N minutes), and the time to enter the sleep mode is not limited thereto.

When the first washing device 100 enters the sleep mode, the first user interface 401 corresponding to the first washing device 100 is turned off. When the first user interface 401 is turned off, this means that the screen of the first user interface 401 displays an operation screen in which all illumination except the LED lamp of the first start button 403-2 is slowly dimmed and turned off.

As described above, in a state where the first washing device 100 enters the sleep mode, the controller 500 may determine whether the first door 160 of the first washing device 100 is opened (1212).

As a result of the determination of operation 1212, when the first door 160 of the first washing device 100 is not opened, the first washing device 100 may return to operation 1210 and perform a subsequent operation while maintaining the sleep mode.

Meanwhile, in operation 1212, when the first door 160 of the first washing device 100 is opened, the first washing device 100 may perform operation 1308 to re-enter the active mode as an operation-ready state.

Meanwhile, in a state where the power of the first and second washing devices 100 and 200 is simultaneously turned on due to the power button 403-1 being turned on in the operation 1300, the controller 500 may determine whether the power of the second washing device 200 is turned on (1222).

When the power of the second washing device 200 is turned on, the second washing device 200 may enter an operation ready state (1224).

When the second washing device 200 enters the operation ready state, the user may input buttons for selecting a washing course and options of the second washing device 200 using the user interface 400.

Accordingly, the controller 500 may determine whether there is a button input of the second user interface 402 corresponding to the second washing device 200 (1226).

As a result of the determination of operation 1226, when there is a button input of the second user interface 402, the second washing device 200 may perform a subsequent operation while maintaining the activation mode as an operation ready state.

Meanwhile, when there is no button input of the second user interface 402, the second washing device 200 may enter the sleep mode in operation 1226 (1230). The time to enter the sleep mode may be when no button input of the second user interface 402 corresponding to the second washing device 200 is continued for a predetermined time (N minutes), and the time to enter the sleep mode is not limited thereto.

When the second washing device 200 enters the sleep mode, the second user interface 402 corresponding to the second washing device 200 is turned off.

As described above, in the state where the second washing device 200 enters the sleep mode, the controller 500 may determine whether the second door 260 of the second washing device 200 is opened (1232).

As a result of the determination of operation 1232, when the second door 260 of the second washing device 200 is not opened, the second washing device 200 may return to operation 1230 and perform a subsequent operation while maintaining the sleep mode.

Meanwhile, in operation 1232, when the second door 260 of the second washing device 200 is opened, the second washing device 200 may perform operation 1328 to re-enter the active mode as the operation ready state.

Meanwhile, in an embodiment of the present disclosure, in the case where the first and second doors 160 and 260 are opened while the first and second user interfaces 401 and 402 are operated in the sleep mode, the first and second user interfaces 401 and 402 are switched to the active mode, but the present disclosure is not limited thereto. The first and second user interfaces 401 and 402 may be configured to switch to the active mode even when the first and second doors 160 and 260 are closed while the first and second user interfaces 401 and 402 are operated in the sleep mode.

Next, a method of switching the first and second user interfaces 406 and 407 from the sleep mode to the active mode by using the first and second power buttons 406-1 and 407-1 when the first and second power buttons 406-1 and 407-1 are formed in the first and second user interfaces 406 and 407, respectively, will be described with reference to fig. 10 to 19.

Fig. 10 is a view illustrating a control panel of a washing machine according to another embodiment of the present disclosure.

Referring to fig. 10, a user interface 400 may be provided in the control panel 50 to interact with a user. For example, the user interface 400 may receive user inputs for the first and second washing devices 100 and 200 from a user, and may display the user inputs or operation information corresponding to the process status.

Referring to fig. 11, the user may turn on a first power button 406-1(1800) of a first user interface 406 provided on the control panel 50.

When the first power button 406-1 is turned on, the first washing device 100 is turned on at the same time as the first user interface 406, which has been turned off as shown in fig. 12, is turned on as shown in fig. 13.

In a state where the power of the first washing device 100 is turned on, the controller 500 may determine whether the power of the first washing device 100 is turned on (1802).

When the power of the first washing device 100 is turned on, the first washing device 100 may enter an operation ready state (1804).

When the first washing device 100 enters the operation ready state, the user may select a washing course and an option of the first washing device 100 using the first user interface 406 (1806).

Subsequently, the controller 500 may determine whether the washing course and selection of the option of the first washing device 100 are completed (1808).

As a result of the determination of the operation 1808, when the selection of the washing course and the option of the first washing device 100 is not completed, the controller 500 may return to the operation 1806 for a subsequent operation.

In operation 1808, when the selection of the wash course and option of the first washing device 100 is completed, the user may select the first start button 406-2(1810) of the first washing device 100.

When the first start button 406-2 is selected, the first washing device 100 may start an operation according to the selected wash course and option, and perform a washing course, a rinsing course, and a dehydrating course (1812).

When the operation of the first washing device 100 is initiated, as shown in fig. 14, a first cancel button 406-3 may be activated in the first user interface 406.

As such, when the user selects the first washing cancellation button 406-3 of the first washing device 100 while the washing, rinsing, and spinning processes of the first washing device 100 are performed, the controller 500 may determine whether the first washing cancellation button 406-3 is selected (1814).

As a result of the determination of operation 1814, when the first washing cancel button 406-3 is not selected, the controller 500 may return to operation 1812 to continue the process of the first washing device 100.

In operation 1814, when the first washing cancel button 406-3 is selected, the controller 500 may cancel the process of the first washing device 100 (1816).

Subsequently, the controller 500 may count the time at which the process of the first washing device 100 is cancelled by using the built-in timer 503, and determine whether the counted time has elapsed a predetermined time (N minutes; about 3 minutes as a reference time for determining whether the process of the first washing device is cancelled) (1818). This is to determine whether a predetermined time (about 3 minutes) has elapsed since the first wash cancel button 406-3 was selected, because the user may erroneously press the first wash cancel button 406-3.

As a result of the determination of operation 1818, when a predetermined time (N minutes) elapses while the process of the first washing device 100 is canceled, the controller 500 may determine that the predetermined time elapses after the first washing cancel button 406-3 is selected.

Accordingly, after a predetermined time elapses after the first washing cancel button 406-3 is selected, the controller 500 may turn off the power of the first washing device 100 (1820) and terminate the operation.

On the other hand, when the user turns off the first power button 406-1 during the processes (the washing process, the rinsing process, and the dehydrating process) of the first washing device 100 in operation 1812, the controller 500 may determine whether the first power button 406-1 is turned off (1815).

As a result of the determination in operation 1815, when the first power button 406-1 is not turned off, the controller 500 may return to operation 1812 to continue the process of the first washing device 100.

On the other hand, as a result of the determination of the operation 1815, when the first power button 406-1 is turned off, the controller 500 may perform an operation 1816 to cancel the course of the first washing device 100 and perform a subsequent operation.

Meanwhile, the user may turn on the second power button 407-1(1900) of the second user interface 407 provided on the control panel 50.

When the second power button 407-1 is turned on, the second washing device 200 is turned on while the second user interface 407, which has been turned off as shown in fig. 15, is turned on as shown in fig. 16.

In a state where the power of the second washing device 200 is turned on, the controller 500 may determine whether the power of the second washing device 200 is turned on (1902).

When the power of the second washing device 200 is turned on, the second washing device 200 may enter an operation ready state (1904).

When the second washing device 200 enters the operation ready state, the user may select a washing course and options of the second washing device 200 using the second user interface 407 (1906).

Subsequently, the controller 500 may determine whether the washing course and selection of the option of the second washing device 200 are completed (1908).

As a result of the determination of operation 1908, when the selection of the washing course and option of the second washing device 200 is not completed, the controller 500 may return to operation 1906 for a subsequent operation.

In operation 1908, when the selection of the wash course and option of the second washing device 200 is completed, the user may select the second start button 407-2(1910) of the second washing device 200.

When the second start button 407-2 is selected, the second washing device 200 may start an operation according to the selected wash course and option, and perform a washing course, a rinsing course, and a dehydrating course (1912).

When the operation of the second washing device 200 is initiated, as shown in fig. 17, a second cancel button 407-3 may be activated in the second user interface 407.

As such, when the user selects the second washing cancellation button 406-3 of the second washing device 200 while the washing process, the rinsing process, and the dehydrating process of the second washing device 200 are performed, the controller 500 may determine whether the second washing cancellation button 407-3 is selected (1914).

As a result of the determination of operation 1914, when the second washing cancel button 407-3 is not selected, the controller 500 may return to operation 1912 to continue the process of the second washing device 200.

In operation 1914, when the second washing cancel button 407-3 is selected, the controller 500 may cancel the process of the second washing device 200 (1916).

Subsequently, the controller 500 may count the time at which the process of the second washing device 200 is cancelled by using the built-in timer 503, and determine whether the counted time has elapsed a predetermined time (N minutes; about 3 minutes as a reference time for determining whether the process of the second washing device is cancelled) (1918). This is to determine whether a predetermined time (about 3 minutes) has elapsed since the second washing cancel button 407-3 was selected, because the user may erroneously press the second washing cancel button 407-3.

As a result of the determination of operation 1918, when a predetermined time (N minutes) elapses while the process of the second washing device 200 is cancelled, the controller 500 may determine that the predetermined time elapses after the second washing cancel button 407-3 is selected.

Accordingly, after a predetermined time elapses after the second washing cancel button 407-3 is selected, the controller 500 may turn off the power of the second washing device 200 (1920) and terminate the operation.

On the other hand, when the user turns off the second power button 407-1 during the course of the second washing device 200 (the washing course, the rinsing course, and the spinning course) in operation 1912, the controller 500 may determine whether the second power button 407-1 is turned off (1915).

As a result of the determination in operation 1915, when the second power button 407-1 is not turned off, the controller 500 may return to operation 1912 to continue the course of the second washing device 200.

On the other hand, as a result of the determination of the operation 1915, when the second power button 407-1 is turned off, the controller 500 may perform an operation 1916 to cancel the course of the second washing device 200 and perform a subsequent operation.

Next, a process of entering the sleep mode when a predetermined time elapses without an input to the button of the first user interface 406 or the second user interface 407 will be described with reference to fig. 18.

Fig. 18 is a flowchart illustrating a sleep mode control algorithm of a washing machine according to another embodiment of the present disclosure.

Referring to fig. 18, the user may turn on a first power button 406-1(2100) of the first user interface 406 provided in the control panel 50.

When the first power button 406-1 is turned on, the first washing device 100 is turned on at the same time as the first user interface 406 (see fig. 14 and 15) that has been turned off is turned on.

When the power of the first washing device 100 is turned on, the controller 500 may determine whether the power of the first washing device 100 is turned on (2102).

When the power of the first washing device 100 is turned on, the first washing device 100 may enter an activation mode as an operation ready state (2104).

When the first washing device 100 enters the operation ready state, the controller 500 may determine whether there is a button input of the first user interface 406 corresponding to the first washing device 100 (2106).

As a result of the determination of operation 2106, when there is a button input of the first user interface 406, the first washing device 100 may perform a subsequent operation while maintaining the activation mode as the operation ready state.

Meanwhile, in operation 2106, when there is no button input of the first user interface 406, the first washing device 100 may enter the sleep mode (2110). The time to enter the sleep mode may be when no button input of the first user interface 406 corresponding to the first washing device 100 is continued for a predetermined time (N minutes), and the time to enter the sleep mode is not limited thereto.

When the first washing device 100 enters the sleep mode, the first user interface 406 corresponding to the first washing device 100 is turned off. When the first user interface 406 is turned off, this means that the screen of the first user interface 406 displays an operation screen in which all illumination except the LED lamp of the first start button 406-2 is slowly dimmed and turned off.

As described above, in a state where the first washing device 100 enters the sleep mode, the controller 500 may determine whether there is a button input of the first user interface 406 corresponding to the first washing device 100 (2112).
