Description

[0001] This application is a divisional application of the patent application filed on November 17, 2017, with application number 201780090985.3 and entitled "Washing Machine". Technical Field

[0002] This disclosure relates to a washing machine having multiple washing units. Background Technology

[0003] Generally, a washing machine includes a washing unit (washing tub) and is a device that uses water and detergent to remove contaminants from clothes. The washing machine uses a motor as its main power source to perform the washing of clothes through a series of operations such as washing, rinsing, and spin-drying processes. In modern times, washing machines are also configured to have a drying function, allowing them to perform the drying process for clothes after spin-drying.

[0004] During washing, a washing machine may not be able to wash multiple garments contained in one washing unit simultaneously, based on their type or material. Because a conventional washing machine has only one washing unit, the user must sort the multiple garments into different types before the washing machine starts operating, and select only those garments that cannot be washed in one washing machine at the same time.

[0005] In this situation, users may experience inconvenience because they must select only a few items from their entire wardrobe for a separate wash cycle, and the washing machine must be run several times (e.g., twice), resulting in wasted energy and time. Furthermore, even if users expect to use the washing machine to wash a small number of clothes, unnecessary power consumption can occur if the washing machine has a large-capacity drum. Summary of the Invention

[0045] Additionally, the washing machine 1 may include a control panel 50 disposed on the front cover 40 for operating the washing machine 1. The control panel 50 is provided with a user interface 400 for receiving washing setting information related to the operation of the washing machine 1 and displaying various information to the user. The user interface 400 may include: an input device for receiving user commands from the user; and a display for displaying various operating information of the washing machine 1 to the user based on the input user commands. For user convenience, the user interface 400 may be provided on the front of the washing machine 1. (Refer to...) Figure 2 Describe the user interface 400.

[0046] Figure 2 This is a view showing the control panel of a washing machine according to one embodiment of the present disclosure.

[0047] Reference Figure 2 The user interface 400 can be provided in the control panel 50 for user interaction. For example, the user interface 400 can receive user input for the first washing device 100 and the second washing device 200, and can display user input or operation information corresponding to the process status.

[0048] The user interface 400 may include: a first user interface 401 provided in the lower area of ​​the control panel 50 and configured to receive a first control command for controlling the first washing device 100; and a second user interface 401 provided in the upper area of ​​the control panel 50 and configured to receive a second control command for controlling the second washing device 200.

[0049] The first user interface 401 and the second user interface 402 can operate in active mode and sleep mode. In active mode, the first washing device 100 and the second washing device 200 are controlled according to the first control command and the second control command, respectively. In sleep mode, the first washing device 100 and the second washing device 200 are not controlled according to the first control command and the second control command, respectively.

[0050] The first user interface 401 and the second user interface 402 may include multiple buttons (e.g., appointment, wash water temperature, number of rinses, wash, rinse, spin-dry, water level selection, etc.), and user commands related to the operation of the washing machine 1 are input through these multiple buttons. The multiple buttons may include a wash water temperature button for selecting the wash water temperature, a number of rinses button for selecting the number of rinses, and a process selection button for selecting the washing process (such as standard process, wool process, boiling process, drying process, etc.) according to the type of clothing.

[0051] Additionally, the first user interface 401 and the second user interface 402 may include extra option buttons for simultaneously controlling the first washing device 100 and the second washing device 200.

[0052] The user interface 400 may also include a third user interface 403, which is provided in the lower area of ​​the control panel 50 and receives third control commands for switching the first user interface 401 and the second user interface 402 from hibernation mode to active mode.

[0053] The third user interface 403 may include an integrated power button 403-1 (hereinafter referred to as the "power button") for simultaneously controlling the power supply of the first washing device 100 and the second washing device 200, a first start button 403-2 (START / PAUSE button) for starting or pausing the operation of the first washing device 100, and a second start button 403-3 (START / PAUSE button) for starting or pausing the operation of the second washing device 200.

[0054] The power button 403-1 is configured to simultaneously turn the power to the first washing device 100 and the second washing device 200 on or off with a single button.

[0055] The first start button 403-2 and the second start button 403-3 are configured separately because there are no separate power buttons for the first washing device 100 and the second washing device 200.

[0056] Figure 3 This is a control block diagram of a washing machine according to one embodiment of the present disclosure.

[0057] Reference Figure 3 The washing machine 1 may also include a user interface 400, a controller 500, a storage unit 510, a drive 520, and a sound output device 530.

[0058] The user interface 400 can interact with the user. For example, the user interface 400 can receive user input for the first washing device 100 and the second washing device 200, and can display the user input or operation information corresponding to the process status.

[0059] For user convenience, the user interface 400 can be installed at the front of the washing machine 1. For example, as Figure 1 As shown, the user interface 400 can be installed in the control panel 50. In the following text, the installation of the user interface 400 on the control panel 50 is used as an example, but the installation location of the user interface 400 is not limited to this. For example, the user interface 400 can be installed anywhere the user can operate and view it.

[0060] Additionally, the user interface 400 may include a wake-up function that is automatically activated when a user approaches within a certain range. For example, the user interface 400 can be activated when a user approaches within a certain range. In other words, the user interface 400 can be turned on. On the other hand, the user interface 400 can be deactivated when the user leaves the certain range. In other words, the user interface 400 can be turned off.

[0061] The controller 500 can control all operations of the washing machine 1, such as the washing process, rinsing process and spin-drying process, based on the washing operation information input from the user interface 400, and may include a microprocessor 501, a memory 502 and a timer 503.

[0062] The timer 503 can count the operating time of the first washing device 100 and the second washing device 200.

[0063] After the power button 401 is turned on, if there is no button input from any of the multiple washing devices 100 and 200 after a predetermined time (approximately 3 minutes), the controller 500 can control the user interface 400 to enter a sleep mode. The controller 500 can minimize power consumption by entering sleep mode and clearly distinguish between the running washing device 100 or 200 and the non-running washing device 200 or 100.

[0064] In addition, after entering sleep mode, the controller 500 can release the sleep mode by inputting the wake-up button or by inputting all the buttons on the user interface 400.

[0065] After the power button 401 is turned on, the controller 500 can turn off the washing machine 1 if no button input is made at the two washing units 100 and 200 after a predetermined time (approximately 3 minutes).

[0066] In addition, the controller 500 can control the drive of the user interface 400 to display washing operation information based on the user's operation commands.

[0067] The storage unit 510 can store control programs and control data for controlling the operation of the washing machine 1, as well as various application programs and application data for performing various functions based on user input.

[0068] The driver 520 can drive the water supply device 310, detergent supply device 320, first drain pump 170 and second drain pump 270, as well as the first drive motor 140 and second drive motor 240 related to the operation of the washing machine 1, according to the drive control signal of the controller 500.

[0069] The sound output device 530 may include a speaker 531 that converts electrical signals into sound. Here, the sound output device 530 can receive electro-sound signals from the controller 500 and output sound corresponding to the received electro-sound signals.

[0070] The operation process and effects of the washing machine according to the embodiments of this disclosure will be described in detail below.

[0071] First, refer to Figures 4 to 7 The process of turning the control panel 50 of the first washing device 100 and the second washing device 200 on and off using an integrated power supply, and canceling the first washing device 100 or the second washing device 200 by means of the wash cancellation buttons 404 and 405 is described.

[0072] Figure 4 This is a flowchart illustrating an integrated power mode control algorithm for a washing machine according to an embodiment of the present disclosure. Figure 5 This is a view showing the control panel of a washing machine with multiple washing devices in a state where the integrated power supply is turned off, according to an embodiment of the present disclosure. Figure 6 This is a view showing the control panel of a washing machine with multiple washing devices in an embodiment of the present disclosure in a state where the integrated power supply is turned on. Figure 7 This is a view showing the state in which the wash cancel button in a washing machine according to an embodiment of the present disclosure is activated on the right side of the control panel.

[0073] Reference Figure 4 Users can turn on the power button 403-1 (700) provided on the third user interface 403 on the control panel 50.

[0074] When the power button 403-1 is turned on, in the already... Figure 5 The closed user interface 400 is shown. Figure 6 As shown, when the device is turned on, the first washing device 100 and the second washing device 200 are turned on simultaneously.

[0075] When the power supplies to the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 can determine whether the power supply to the first washing device 100 is turned on (802).

[0076] When the power supply to the first washing device 100 is turned on, the first washing device 100 can enter the operation ready state (804).

[0077] When the first washing device 100 enters the operation-ready state, the user can use the first user interface 401 to select the washing process and options of the first washing device 100 (806). The washing process may include standard process, gentle process, wool process, towel process, bedding process, etc., and the options may include washing water temperature, number of rinses, spin-drying intensity, etc.

[0078] Subsequently, the controller 500 can determine whether the washing process and option selection of the first washing device 100 have been completed (808).

[0079] As a result of operation 808, if the selection of the washing process and options of the first washing device 100 is not completed, the controller 500 can return to operation 806 to perform subsequent operations.

[0080] In operation 808, when the washing process and options of the first washing device 100 are selected, the user can select the first start button 403-2 (810) of the first washing device 100.

[0081] When the first start button 403-2 is selected, the first washing device 100 can start operation and perform the washing process, rinsing process and dehydration process (812) according to the selected washing process and option.

[0082] When the operation of the first washing device 100 is started, such as Figure 7 As shown, the first wash cancel button 404 and the second wash cancel button 405 can be activated in the user interface 400.

[0083] Accordingly, when the user selects the first wash cancel button 404 of the first washing device 100 during the washing process, rinsing process and spin-drying process of the first washing device 100, the controller 500 can determine whether the first wash cancel button 404 has been selected (814).

[0084] As a result of operation 814, when the first wash cancel button 404 is not selected, the controller 500 can return to operation 812 to continue the process of the first wash device 100.

[0085] In operation 814, when the first wash cancel button 404 is selected, the controller 500 can cancel the process of the first wash device 100 (816).

[0086] Subsequently, the controller 500 can count the time during which the process of the first washing device 100 has been cancelled using the built-in timer 503, and determine whether the counted time has elapsed for a predetermined time (N minutes; a reference time for determining whether the process of the first washing device has been cancelled, approximately 3 minutes) (818). This is to determine whether a predetermined time (approximately 3 minutes) has elapsed since the first wash cancellation button 404 was selected, as the user may accidentally press the first wash cancellation button 404.

[0087] As a result of operation 818, when the time for canceling the process of the first washing device 100 has elapsed after a predetermined time (N minutes), the controller 500 can determine that a predetermined time has elapsed since the first washing cancellation button 404 was selected.

[0088] Therefore, after a predetermined time has elapsed since the first wash cancel button 404 was selected, the controller 500 can turn off the power (820) of the first washing device 100 and terminate the operation.

[0089] Meanwhile, when the power supply to the first washing device 100 and the second washing device 200 is simultaneously turned on due to the power button 403-1 being turned on during operation 700, the controller 500 can determine whether the power supply to the second washing device 200 is turned on (902).

[0090] When the power supply to the second washing device 200 is turned on, the second washing device 200 can enter the operation ready state (904).

[0091] When the second washing device 200 enters the operation-ready state, the user can use the second user interface 402 to select the washing process and options of the second washing device 200 (906). Subsequently, the controller 500 can determine whether the selection of the washing process and options of the second washing device 200 is complete (908).

[0092] As a result of operation 908, if the selection of the washing process and options of the second washing device 200 is not completed, the controller 500 can return to operation 906 to perform subsequent operations.

[0093] In operation 908, when the washing process and options of the second washing device 200 are selected, the user can select the second start button 403-3 (910) of the second washing device 200.

[0094] When the second start button 403-3 is selected, the second washing device 200 can start operation and perform the washing process, rinsing process and dehydration process (912) according to the selected washing process and option.

[0095] When the operation of the second washing device 200 is started, such as Figure 9 As shown, the first wash cancel button 404 and the second wash cancel button 405 can be activated in the user interface 400.

[0096] Accordingly, when the user selects the second wash cancel button 405 of the second washing device 200 during the washing process, rinsing process and spin-drying process of the second washing device 200, the controller 500 can determine whether the second wash cancel button 405 has been selected (914).

[0097] As a result of operation 914, when the second wash cancel button 405 is not selected, the controller 500 can return to operation 912 to continue the process of the second washing device 200.

[0098] In operation 914, when the second wash cancel button 405 is selected, the controller 500 can cancel the process of the second wash device 200 (916).

[0099] Subsequently, the controller 500 can count the time during which the process of the second washing device 200 has been cancelled using the built-in timer 503, and determine whether the counted time has elapsed for a predetermined time (N minutes; a reference time for determining whether the process of the second washing device has been cancelled, approximately 3 minutes) (918). This is to determine whether a predetermined time (approximately 3 minutes) has elapsed since the second washing cancellation button 405 was selected, as the user may accidentally press the second washing cancellation button 405.

[0100] As a result of operation 918, when the time for canceling the process of the second washing device 200 has elapsed after a predetermined time (N minutes), the controller 500 can determine that a predetermined time has elapsed since the second washing cancellation button 405 was selected.

[0101] Therefore, after a predetermined time has elapsed since the second wash cancel button 405 has been selected, the controller 500 can turn off the power (920) of the second washing device 200 and terminate the operation.

[0102] On the other hand, during operations 812 and 912, during the process of the first washing device 100 and the second washing device 200 (washing process, rinsing process and spin-drying process), when the user turns off the power button 403-1, the controller 500 can determine whether the power button 403-1 is turned off (702).

[0103] As a result of operation 702, when the power button 403-1 is not turned off, the controller 500 can return to operations 812 and 912 to continue the process of the first washing device 100 and the second washing device 200.

[0104] On the other hand, as a result of operation 702, when the power button 403-1 is turned off, the controller 500 can perform operations 816 and 916 to cancel the process of the first washing device 100 and the second washing device 200 and perform subsequent operations.

[0105] Accordingly, the washing machine 1 according to one embodiment of this disclosure can simultaneously turn the power to the first washing unit 100 and the second washing unit 200 on or off using a power button 403-1 provided on the control panel 50. That is, one power button 403-1 can perform the function of an integrated power supply. Next, reference will be made to... Figure 8 Describes the process of entering sleep mode when no button input is made to the first user interface 401 or the second user interface 402 after a predetermined time.

[0106] Figure 8 This is a flowchart illustrating a sleep mode control algorithm for a washing machine according to an embodiment of the present disclosure.

[0107] Reference Figure 8 Users can turn on the power button 403-1 (1000) provided in the user interface 400 in the control panel 50.

[0108] When the power button 403-1 is turned on, the previously closed user interface 400 is turned on (see...). Figure 5 and Figure 6 At the same time, the first washing device 100 and the second washing device 200 are turned on simultaneously.

[0109] When the power supplies to the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 can determine whether the power supply to the first washing device 100 is turned on (1102).

[0110] When the power supply to the first washing device 100 is turned on, the first washing device 100 can enter the activation mode (1104) as an operation-ready state.

[0111] When the first washing device 100 enters the operation-ready state, the user can use the user interface 400 to input buttons for selecting the washing process and options of the first washing device 100.

[0112] Therefore, the controller 500 can determine whether there is a button input (1106) on the first user interface 401 corresponding to the first washing device 100.

[0113] As a result of operation 1106, when there is button input on the first user interface 401, the first washing device 100 can perform subsequent operations while maintaining the active mode as an operation-ready state.

[0114] Meanwhile, in operation 1106, when there is no button input on the first user interface 401, the first washing device 100 can enter a sleep mode (1110). The time for entering the sleep mode can be when there is no button input on the first user interface 401 corresponding to the first washing device 100 for a predetermined time (N minutes), and the time for entering the sleep mode is not limited to this.

[0115] When the first washing device 100 enters 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 lighting except for the LED light of the first start button 403-2 gradually dims and turns off.

[0116] As described above, when the first washing device 100 is in sleep mode, the controller 500 can determine whether there is button input (1112) on the first user interface 401 corresponding to the first washing device 100.

[0117] As a result of operation 1112, when there is no button input on the first user interface 401, the first washing device 100 can return to operation 1110 and perform subsequent operations while maintaining the sleep mode.

[0118] Meanwhile, during operation 1112, when there is button input on the first user interface 401, the first washing device 100 can perform operation 1108 to re-enter the activation mode as an operation-ready state.

[0119] Meanwhile, when the power supply to the first washing device 100 and the second washing device 200 is turned on simultaneously due to the power button 403-1 being turned on during operation 1000, the controller 500 can determine whether the power supply to the second washing device 200 is turned on (1122).

[0120] When the power supply to the second washing device 200 is turned on, the second washing device 200 can enter the operation ready state (1124).

[0121] When the second washing device 200 enters the operation-ready state, the user can use the user interface 400 to input buttons for selecting the washing process and options of the second washing device 200.

[0122] Therefore, the controller 500 can determine whether there is a button input (1126) on the second user interface 402 corresponding to the second washing device 200.

[0123] As a result of operation 1126, when there is button input on the second user interface 402, the second washing device 200 can perform subsequent operations while maintaining the active mode as an operation-ready state.

[0124] Meanwhile, in operation 1126, when there is no button input on the second user interface 402, the second washing device 200 can enter a sleep mode (1130). The time for entering the sleep mode can be when there is no button input on the second user interface 402 corresponding to the second washing device 200 for a predetermined time (N minutes), and the time for entering the sleep mode is not limited to this.

[0125] When the second washing device 200 enters 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 lighting except for the LED light of the second start button 403-3 gradually dims and turns off. As described above, when the second washing device 200 is in sleep mode, the controller 500 can determine whether there is button input (1132) on the second user interface 402 corresponding to the second washing device 200.

[0126] As a result of operation 1132, when there is no button input on the second user interface 402, the second washing device 200 can return to operation 1130 and perform subsequent operations while maintaining the sleep mode.

[0127] Meanwhile, during operation 1132, when there is button input on the second user interface 402, the second washing device 200 can perform operation 1128 to re-enter the activation mode as an operation-ready state.

[0128] Next, when the first washing device 100 or the second washing device 200 enters sleep mode after a predetermined time without button input, the first washing device 100 or the second washing device 200 can provide various display screens for the sleep mode.

[0129] For example, if the second washing device 200 enters a sleep mode in either the first washing device 100 or the second washing device 200, after entering the sleep mode, the second washing device 200 may display a screen with the phrase "touch wake-up" on the upper part of the second user interface 402 corresponding to the second washing device 200.

[0130] In addition, when the second washing device 200 enters a sleep mode, it can display a screen after entering the sleep mode, on which the LED light of the second start button 403-3 corresponding to the second washing device 200 slowly and repeatedly brightens and then dims.

[0131] When the second washing device 200 enters a sleep mode, it can display a screen that provides the phrase "sleep" on the 7th segment (18:88) of the second user interface 402 corresponding to the second washing device 200 after entering the sleep mode.

[0132] Furthermore, when the second washing device 200 enters a sleep mode, after entering the sleep mode, the second washing device 200 can display a screen as an icon at the top of the second user interface 402 corresponding to the second washing device 200 to notify that it has entered the sleep mode.

[0133] Next, when the first washing device 100 or the second washing device 200 enters a sleep mode after a predetermined time without button input, the first washing device 100 or the second washing device 200 can provide various display screens for releasing the sleep mode by waking up.

[0134] For example, when the sleep mode of the second washing device 200 is released between the first washing device 100 and the second washing device 200, the second washing device 200 may display a screen for releasing the sleep mode by touching "touch wake-up", which is provided on the upper part of the user interface 402 corresponding to the second washing device 200 in the sleep mode of the second washing device 200.

[0135] In this case, the sleep mode can be released by selecting any button on the second user interface 402 corresponding to the second washing device 200, but is not limited to this.

[0136] In addition, when the second washing device 200 is released from its sleep mode in the first washing device 100 and the second washing device 200, when the user wakes the second washing device 200 from its sleep mode, the second washing device 200 can display an operation screen in which the lighting is turned on sequentially from the center of the second user interface 402 to both sides.

[0137] In addition, when the second washing device 200 is released from its sleep mode between the first washing device 100 and the second washing device 200, when the user wakes up the second washing device 200 from its sleep mode, the second washing device 200 can display an operation screen in which the lighting is turned on sequentially from the left to the right of the second user interface 402.

[0138] When the second washing device 200 is released from its sleep mode in the first washing device 100 and the second washing device 200, when the user wakes the second washing device 200 from its sleep mode, the second washing device 200 can display an operation screen in which the lighting is turned on sequentially from the position where the second user interface 402 is touched to the left and right.

[0139] Furthermore, when the second washing device 200 is released from its sleep mode between the first washing device 100 and the second washing device 200, the second washing device 200 can display an operation screen in which the overall lighting gradually brightens when the user wakes up the sleep mode of the second washing device 200.

[0140] Next, we will refer to Figure 9 The process describes how, when the user is in sleep mode after a predetermined time has elapsed without any button input to the first user interface 401 or the second user interface 402, the first user interface 401 or the second user interface 402 is switched to active mode by opening the first door 160 or the second door 260.

[0141] Figure 9 This is a flowchart illustrating an activation mode switching control algorithm for a washing machine according to one embodiment of the present disclosure.

[0142] Reference Figure 9 The user turns on the power button 403-1 (1200) provided on the user interface 400 on the control panel 50.

[0143] When the power button 403-1 is turned on, the previously closed user interface 400 is activated (see [link]). Figure 5 and Figure 6 At the same time, the first washing device 100 and the second washing device 200 are turned on simultaneously.

[0144] When the power supplies to the first washing device 100 and the second washing device 200 are simultaneously turned on, the controller 500 can determine whether the power supply to the first washing device 100 is turned on (1202).

[0145] When the power supply to the first washing device 100 is turned on, the first washing device 100 can enter the operation ready state (1204).

[0146] When the first washing device 100 enters the operation-ready state, the user can use the first user interface 401 to input buttons for selecting the washing process and options of the first washing device 100.

[0147] Therefore, the controller 500 can determine whether there is a button input (1206) corresponding to the first washing device 100.

[0148] As a result of operation 1206, when a button is input, the first washing device 100 can perform subsequent operations while maintaining the operation-ready state.

[0149] Meanwhile, in operation 1206, when there is no button input on the first user interface 401, the first washing device 100 can enter a sleep mode (1210). The time for entering the sleep mode can be when there is no button input on the first user interface 401 corresponding to the first washing device 100 for a predetermined time (N minutes), and the time for entering the sleep mode is not limited to this.

[0150] When the first washing device 100 enters 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 lighting except for the LED light of the first start button 403-2 gradually dims and turns off.

[0151] As described above, when the first washing device 100 is in sleep mode, the controller 500 can determine whether the first door 160 of the first washing device 100 is opened (1212).

[0152] As a result of operation 1212, when the first door 160 of the first washing device 100 is not opened, the first washing device 100 can return to operation 1210 and perform subsequent operations while maintaining the sleep mode.

[0153] Meanwhile, in operation 1212, when the first door 160 of the first washing device 100 is opened, the first washing device 100 can perform operation 1308 to re-enter the activation mode as an operation-ready state.

[0154] Meanwhile, when the power supply to the first washing device 100 and the second washing device 200 is turned on simultaneously due to the power button 403-1 being turned on during operation 1300, the controller 500 can determine whether the power supply to the second washing device 200 is turned on (1222).

[0155] When the power supply to the second washing device 200 is turned on, the second washing device 200 can enter the operation ready state (1224).

[0156] When the second washing device 200 enters the operation-ready state, the user can use the user interface 400 to input buttons for selecting the washing process and options of the second washing device 200.

[0157] Therefore, the controller 500 can determine whether there is a button input (1226) on the second user interface 402 corresponding to the second washing device 200.

[0158] As a result of operation 1226, when there is button input on the second user interface 402, the second washing device 200 can perform subsequent operations while maintaining the active mode as an operation-ready state.

[0159] Meanwhile, in operation 1226, when there is no button input on the second user interface 402, the second washing device 200 can enter a sleep mode (1230). The time for entering the sleep mode can be when there is no button input on the second user interface 402 corresponding to the second washing device 200 for a predetermined time (N minutes), and the time for entering the sleep mode is not limited to this.

[0160] When the second washing device 200 enters sleep mode, the second user interface 402 corresponding to the second washing device 200 is turned off.

[0161] As described above, when the second washing device 200 is in sleep mode, the controller 500 can determine whether the second door 260 of the second washing device 200 is opened (1232).

[0162] As a result of operation 1232, when the second door 260 of the second washing device 200 is not opened, the second washing device 200 can return to operation 1230 and perform subsequent operations while maintaining the sleep mode.

[0163] Meanwhile, in operation 1232, when the second door 260 of the second washing device 200 is opened, the second washing device 200 can perform operation 1328 to re-enter the activation mode as an operation-ready state.

[0164] Meanwhile, in one embodiment of this disclosure, when the first door 160 and the second door 260 are opened while the first user interface 401 and the second user interface 402 are operating in sleep mode, the first user interface 401 and the second user interface 402 switch to active mode, but this disclosure is not limited thereto. Even if the first door 160 and the second door 260 are closed while the first user interface 401 and the second user interface 402 are operating in sleep mode, the first user interface 401 and the second user interface 402 can still be configured to switch to active mode.

[0165] Next, we will refer to Figures 10 to 19 The method describes a method for switching the first user interface 406 and the second user interface 407 from sleep mode to active mode by using the first power button 406-1 and the second power button 407-1 when the first power button 406-1 and the second power button 407-1 are formed in the first user interface 406 and the second user interface 407 respectively.

[0166] Figure 10 This is a view showing the control panel of a washing machine according to another embodiment of the present disclosure.

[0167] Reference Figure 10 The user interface 400 can be provided in the control panel 50 for user interaction. For example, the user interface 400 can receive user input for the first washing device 100 and the second washing device 200, and can display user input or operation information corresponding to the process status.

[0168] The user interface 400 may include: a first user interface 406 provided in the lower area of ​​the control panel 50 and configured to receive a first control command for controlling the first washing device 100; and a second user interface 407 provided in the lower area of ​​the control panel 50 and configured to receive a second control command for controlling the second washing device 200.

[0169] The first user interface 406 and the second user interface 407 can operate in active mode and sleep mode. In active mode, the first washing device 100 and the second washing device 200 are controlled according to the first control command and the second control command, respectively. In sleep mode, the first washing device 100 and the second washing device 200 are not controlled according to the first control command and the second control command, respectively.

[0170] The first user interface 406 and the second user interface 407 may include multiple buttons (e.g., preset, wash water temperature, rinse cycles, wash, rinse, spin-dry, water level selection, etc.) through which user commands related to the operation of the washing machine 1 are input. Additionally, the first user interface 406 and the second user interface 407 may include extra option buttons for simultaneously controlling the first washing unit 100 and the second washing unit 200.

[0171] In addition, the first user interface 406 and the second user interface 407 may respectively include a first power button 406-1 and a second power button 407-1, and the first power button 406-1 and the second power button 407-1 are configured to receive a first mode switching command and a second mode switching command for switching the first user interface 406 and the second user interface 407 from sleep mode to active mode.

[0172] Additionally, the first user interface 406 and the second user interface 407 may include a first start button 406-2 and a second start button 407-2 for starting or pausing the operation of the first washing device 100 and the second washing device 200.

[0173] The operation process and effects of a washing machine according to another embodiment of the present disclosure, as well as a method for controlling the washing machine, will be described in detail below.

[0174] Figure 11 This is a flowchart illustrating a separate power mode control algorithm for a washing machine according to another embodiment of the present disclosure. Figure 12 This is a view showing the control panel of the first washing device in a washing machine according to another embodiment of the present disclosure in a state where the power supply is turned off separately. Figure 13 This is a view showing the control panel of the first washing device in a washing machine according to another embodiment of the present disclosure in a state where a separate power supply is turned on. Figure 14 This is a view showing the state in which the wash cancel button in a washing machine according to another embodiment of the present disclosure is activated on the control panel of the first washing unit. Figure 15 This is a view showing the control panel of the second washing device in a washing machine according to another embodiment of the present disclosure in a state where the power supply is turned off separately. Figure 16 This is a view showing the control panel of the second washing device in a washing machine according to another embodiment of the present disclosure in a state where it is turned on as a separate power source. Figure 17 This is a view showing the state in which the wash cancel button in a washing machine according to another embodiment of the present disclosure is activated on the control panel of the second washing unit.

[0175] Reference Figure 11 The user can turn on the first power button 406-1 (1800) provided on the first user interface 406 on the control panel 50.

[0176] When the first power button 406-1 is turned on, the first washing device 100 is already in operation. Figure 12 The first user interface 406 shown is closed. Figure 13 It is enabled at the same time as shown.

[0177] When the power supply to the first washing device 100 is turned on, the controller 500 can determine whether the power supply to the first washing device 100 is turned on (1802).

[0178] When the power supply to the first washing device 100 is turned on, the first washing device 100 can enter the operation ready state (1804).

[0179] When the first washing device 100 enters the operation ready state, the user can use the first user interface 406 to select the washing process and options of the first washing device 100 (1806).

[0180] Subsequently, the controller 500 can determine whether the washing process and option selection of the first washing device 100 have been completed (1808).

[0181] As a result of operation 1808, if the selection of the washing process and options of the first washing device 100 is not completed, the controller 500 can return to operation 1806 to perform subsequent operations.

[0182] In operation 1808, when the washing process and options of the first washing device 100 are selected, the user can select the first start button 406-2 (1810) of the first washing device 100.

[0183] When the first start button 406-2 is selected, the first washing device 100 can start operation according to the selected washing process and option, and perform the washing process, rinsing process and dehydration process (1812).

[0184] When the operation of the first washing device 100 is started, such as Figure 14 As shown, the first cancel button 406-3 can be activated in the first user interface 406.

[0185] Accordingly, when the user selects the first wash cancel button 406-3 of the first washing device 100 during the washing process, rinsing process and spin-drying process of the first washing device 100, the controller 500 can determine whether the first wash cancel button 406-3 has been selected (1814).

[0186] As a result of operation 1814, when the first wash cancel button 406-3 is not selected, the controller 500 can return to operation 1812 to continue the process of the first wash device 100.

[0187] In operation 1814, when the first wash cancel button 406-3 is selected, the controller 500 can cancel the process of the first wash device 100 (1816).

[0188] Subsequently, the controller 500 can count the time during which the process of the first washing device 100 has been cancelled using the built-in timer 503, and determine whether the counted time has elapsed for a predetermined time (N minutes; a reference time for determining whether the process of the first washing device has been cancelled, approximately 3 minutes) (1818). This is to determine whether a predetermined time (approximately 3 minutes) has elapsed since the first wash cancellation button 406-3 was selected, as the user may mistakenly press the first wash cancellation button 406-3.

[0189] As a result of operation 1818, when the time for canceling the process of the first washing device 100 has elapsed after a predetermined time (N minutes), the controller 500 can determine that a predetermined time has elapsed since the first washing cancellation button 406-3 was selected.

[0190] Therefore, after a predetermined time has elapsed since the first wash cancel button 406-3 has been selected, the controller 500 can turn off the power (1820) of the first washing device 100 and terminate the operation.

[0191] On the other hand, during operation 1812, during the process of the first washing device 100 (washing process, rinsing process and spin-drying process), when the user turns off the first power button 406-1, the controller 500 can determine whether the first power button 406-1 is turned off (1815).

[0192] As a result of operation 1815, if the first power button 406-1 is not turned off, the controller 500 can return to operation 1812 to continue the process of the first washing device 100.

[0193] On the other hand, as a result of operation 1815, when the first power button 406-1 is turned off, the controller 500 can perform operation 1816 to cancel the process of the first washing device 100 and perform subsequent operations.

[0194] At the same time, the user can turn on the second power button 407-1 (1900) provided on the second user interface 407 on the control panel 50.

[0195] When the second power button 407-1 is turned on, the second washing device 200 is already in operation. Figure 15 The second user interface 407 shown is closed. Figure 16 It is enabled at the same time as shown.

[0196] When the power supply to the second washing device 200 is turned on, the controller 500 can determine whether the power supply to the second washing device 200 is turned on (1902).

[0197] When the power supply to the second washing device 200 is turned on, the second washing device 200 can enter the operation ready state (1904).

[0198] When the second washing device 200 enters the operation-ready state, the user can use the second user interface 407 to select the washing process and options of the second washing device 200 (1906).

[0199] Subsequently, the controller 500 can determine whether the washing process and option selection of the second washing device 200 have been completed (1908).

[0200] As a result of operation 1908, if the selection of the washing process and options of the second washing device 200 is not completed, the controller 500 can return to operation 1906 to perform subsequent operations.

[0201] In operation 1908, when the washing process and options of the second washing device 200 are selected, the user can select the second start button 407-2 (1910) of the second washing device 200.

[0202] When the second start button 407-2 is selected, the second washing device 200 can start operation according to the selected washing process and option, and perform the washing process, rinsing process and dehydration process (1912).

[0203] When the operation of the second washing device 200 is started, such as Figure 17 As shown, the second cancel button 407-3 can be activated in the second user interface 407.

[0204] Accordingly, when the user selects the second wash cancellation button 406-3 of the second washing device 200 during the washing, rinsing and spin-drying processes, the controller 500 can determine whether the second wash cancellation button 407-3 has been selected (1914).

[0205] As a result of operation 1914, when the second wash cancel button 407-3 is not selected, the controller 500 can return to operation 1912 to continue the process of the second wash device 200.

[0206] In operation 1914, when the second wash cancel button 407-3 is selected, the controller 500 can cancel the process of the second wash unit 200 (1916).

[0207] Subsequently, the controller 500 can count the time during which the process of the second washing unit 200 has been cancelled using the built-in timer 503, and determine whether the counted time has elapsed for a predetermined time (N minutes; a reference time for determining whether the process of the second washing unit has been cancelled, approximately 3 minutes) (1918). This is to determine whether a predetermined time (approximately 3 minutes) has elapsed since the second washing cancellation button 407-3 was selected, as the user may mistakenly press the second washing cancellation button 407-3.

[0208] As a result of operation 1918, when the time for canceling the process of the second washing device 200 has elapsed after a predetermined time (N minutes), the controller 500 can determine that a predetermined time has elapsed since the second washing cancellation button 407-3 was selected.

[0209] Therefore, after a predetermined time has elapsed since the second wash cancel button 407-3 has been selected, the controller 500 can turn off the power (1920) of the second washing device 200 and terminate the operation.

[0210] On the other hand, during operation 1912, during the process of the second washing device 200 (washing process, rinsing process and spin-drying process), when the user turns off the second power button 407-1, the controller 500 can determine whether the second power button 407-1 is turned off (1915).

[0211] As a result of operation 1915, if the second power button 407-1 is not turned off, the controller 500 can return to operation 1912 to continue the process of the second washing device 200.

[0212] On the other hand, as a result of operation 1915, when the second power button 407-1 is turned off, the controller 500 can perform operation 1916 to cancel the process of the second washing device 200 and proceed with subsequent operations.

[0213] Next, we will refer to Figure 18 Describes the process of entering sleep mode when no button input is made to the first user interface 406 or the second user interface 407 after a predetermined time has elapsed.

[0214] Figure 18 This is a flowchart illustrating a sleep mode control algorithm for a washing machine according to another embodiment of the present disclosure.

[0215] Reference Figure 18 The user can turn on the first power button 406-1 (2100) provided in the first user interface 406 in the control panel 50.

[0216] When the first power button 406-1 is turned on, the first washing device 100 is activated on the previously closed first user interface 406 (see [link]). Figure 14 and Figure 15 It is activated at the same time.

[0217] When the power supply to the first washing device 100 is turned on, the controller 500 can determine whether the power supply to the first washing device 100 is turned on (2102).

[0218] When the power supply to the first washing device 100 is turned on, the first washing device 100 can enter the activation mode (2104) as an operation-ready state.

[0219] When the first washing device 100 enters the operation ready state, the controller 500 can determine whether there is a button input (2106) on the first user interface 406 corresponding to the first washing device 100.

[0220] As a result of operation 2106, when there is button input on the first user interface 406, the first washing device 100 can perform subsequent operations while maintaining the active mode as an operation-ready state.

[0221] Meanwhile, during operation 2106, when there is no button input on the first user interface 406, the first washing device 100 can enter a sleep mode (2110). The time for entering the sleep mode can be when there has been no button input on the first user interface 406 corresponding to the first washing device 100 for a predetermined time (N minutes), and the time for entering the sleep mode is not limited to this.

[0222] When the first washing device 100 enters 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 lighting except for the LED light of the first start button 406-2 gradually dims and turns off.

[0223] As described above, when the first washing device 100 is in sleep mode, the controller 500 can determine whether there is a button input (2112) on the first user interface 406 corresponding to the first washing device 100.

[0224] As a result of operation 2112, when there is no button input on the first user interface 406, the first washing device 100 can return to operation 2110 and perform subsequent operations while maintaining the sleep mode.

[0225] Meanwhile, during operation 2112, when there is button input on the first user interface 406, the first washing device 100 can perform operation 2108 to re-enter the activation mode as an operation-ready state.

[0226] On the other hand, the user can turn on the second power button 407-1 (2200) provided on the second user interface 407 on the control panel 50.
