Description

Technical Field

[0001] The present disclosure relates to a washing machine capable of providing a plurality of washing modes for washing laundry and a method of controlling the same. Background Art

[0002] A washing machine is a device for washing clothes by rotating its cylindrical rotating drum. Generally, washing machines are divided into two types: a washing machine that washes clothes by rotating the rotating drum with a horizontal axis as a rotating axis so that the clothes rise and fall along the inner wall of the rotating drum; and a washing machine that rotates the rotating drum with a vertical axis as a rotating axis and washes clothes by utilizing a water flow generated by a pulsator.

[0003] Washing machines with a horizontal rotation axis are called front-loading washing machines because the laundry inlet is formed at the front, while washing machines with a vertical rotation axis are called top-loading washing machines because the laundry inlet is formed at the top. In addition, there are washing machines that include multiple washing devices driven by different means to take advantage of the above two types.

[0004] In order to wash clothes, the washing machine performs a washing operation to remove contamination of the clothes with water (particularly washing water) in which detergent is dissolved, a rinsing operation to rinse the clothes with water (particularly rinsing water) without detergent, and a dehydration operation to remove moisture contained in the clothes through high-speed spinning.

[0005] Meanwhile, a top-loading washing machine may include a washing rod mounted to a pulsator. The washing rod may be referred to as an agitator. The washing rod may promote the generation of water flow and friction with the clothes to improve washing efficiency. However, when the pulsator is coupled to the washing rod, a large amount of clothes may not be loaded. Summary of the invention

The washing rod sensor 210 may be configured as a near field communication (NFC) reader, and the identifier 220 may be configured as an NFC tag. In response to the pulsator 110 being coupled to the washing rod 120, the washing rod sensor 210 may detect the NFC tag, and send a detection signal to the controller 400 based on the detection of the NFC tag.

[0094] The wash rod sensor 210 is not limited to the above example, and any type of sensor capable of detecting the coupling of the pulsator 110 and the wash rod 120 may be adopted.

[0095] Figure 6 A control panel of a washing machine according to an embodiment of the present disclosure is illustrated.

[0096] refer to Figure 6 The control panel 70 may obtain various user inputs for operating the washing machine 1. The control panel 70 may also display information related to the operation of the washing machine 1. For example, the control panel 70 may include an adjustment dial 71 and a display 73. The control panel 70 may also include a plurality of buttons and / or a touch screen.

[0097] For example, the control panel 70 may include a power button P for turning on / off the washing machine 1. The washing machine 1 may be turned on or off based on a user pushing or touching the power button P. When a power-on command is input by pushing or touching the power button P, the control panel 70 may display various selectable user interface UI elements.

[0098] The control panel 70 may further include various buttons, such as a start / stop button SP for starting or stopping the operation of the washing machine 1, a water level button WL for selecting a water level, a washing time button WT for selecting a washing time, a rinse number button RT for selecting a rinse number, a spin time button ST for selecting a spin time, a water temperature button (not shown) for selecting a water temperature, and the like. The buttons described above may be provided as physical buttons or touch buttons.

[0099] The control panel 70 may include a rotatable adjustment disk 71 for selecting a washing mode and an indicator 72 for indicating the selected washing mode. The indicator 72 may be implemented as a light emitting diode (LED). The adjustment disk 71 may be provided in a circular shape, and a plurality of LEDs may be provided along the circumference of the adjustment disk 71.

[0100] The user can select one of the plurality of washing modes M by rotating the adjustment dial 71. The indicator 72 can be illuminated according to the rotation of the adjustment dial 71. In addition, the position of the illuminated indicator 72 can change with the rotation of the adjustment dial 71. As the adjustment dial 71 rotates clockwise, the position of the indicator 72 can change to indicate one of the plurality of washing modes M.

[0101] As the adjustment disk 71 rotates, one of the plurality of washing modes M can be sequentially selected. For example, by rotating the adjustment disk 71 clockwise, the first mode, the second mode, the third mode, the fourth mode, the fifth mode, the sixth mode, the seventh mode, the eighth mode, the ninth mode, the tenth mode, the eleventh mode and the twelfth mode can be sequentially selected.

[0102] The plurality of washing modes M illustrated by the first to twelfth modes may include a standard mode, a strong mode, a fast mode, a gentle mode, a soaking mode, a color clothes mode, a bedding mode, a large volume mode, a rinsing mode, a dehydration mode, a water saving mode, and a tub cleaning mode. The washing modes are not limited thereto, and various washing modes may be provided by design.

[0103] The control panel 70 may include an LED for displaying a plurality of washing modes M. Light may be emitted from the LED to display each of the plurality of washing modes M. In other words, the controller 400 may control the control panel 70 so that each of the plurality of washing modes M is illuminated. For example, the controller 400 may control the control panel 70 to display at least one washing mode from among the plurality of washing modes M corresponding to the coupled state of the washing rod 120 or the separated state of the washing rod 120.

[0104] As another example, the adjustment dial 71 may be replaced by a button, and each time the user presses the button, the selection of the washing mode M may be changed. As yet another example, each of the plurality of washing modes M may be provided as a button, and each of the plurality of washing modes M may be selected by each button.

[0105] The display 73 may display various information related to the operation of the washing machine 1. The display 73 may display information input by a user or information provided to a user as various screens. The display 73 may also display a graphical user interface (GUI) that enables control of the washing machine 1.

[0106] For example, the display 73 may display information about detailed options of the washing mode (e.g., water level, washing time, number of rinses, degree of spin drying). The display 73 may also display at least one washing mode corresponding to the connection state of the washing rod 120 or the separation state of the washing rod 120 from among the plurality of washing modes M.

[0107] The control panel 70 is not limited thereto and may have various designs.

[0108] Figure 7 is a block diagram illustrating constituent elements of a washing machine according to an embodiment of the present disclosure.

[0109] refer to Figure 7 The washing machine 1 may include a water supply valve 18, a drain valve 22, a motor 25, a water level sensor 60, a control panel 70, a wash rod sensor 210, a communication interface 300, and a controller 400. The controller 400 may be electrically connected to the components of the washing machine 1 and may control the operations of the components of the washing machine 1.

[0110] The water supply valve 18 may open or close the water supply pipe 17 that supplies water to the tub 11. That is, the supply of water may be controlled by opening or closing the water supply valve 18. The controller 400 may control the opening or closing of the water supply valve 18. The controller 400 may open the water supply valve 18 in response to starting a washing operation or a rinsing operation.

[0111] The drain valve 22 may open or close the drain pipes 21 and 23 to discharge water in the tub 11 to the outside. The controller 400 may control the opening or closing of the drain valve 22. The controller 400 may open the drain valve 22 in response to completion of a washing operation or a rinsing operation.

[0112] The motor 25 can rotate the rotating tub 12 and the pulsator 110 under the control of the controller 400. The rotating tub 12 and the pulsator 110 can rotate alternately in a forward direction and a reverse direction by the operation of the motor 25. The controller 400 can control the rotation speed of the motor 25 by adjusting the magnitude of the current applied to the motor 25. The controller 400 can change the rotation direction of the motor 25.

[0113] The water level sensor 60 may detect the water level in the tub 11. The water level sensor 60 may detect a frequency that varies with the water level. The water level sensor 60 may detect the water level in the tub 11 based on a frequency corresponding to the internal pressure of the tub 11. For example, as the water level increases, the pressure in the tub 11 increases, and the frequency decreases. Conversely, as the water level decreases, the pressure in the tub 11 decreases, and the frequency increases. The water level sensor 60 may send an electrical signal corresponding to the water level in the tub 11 to the controller 400.

[0114] The control panel 70 may include a rotatable dial 71 and buttons for obtaining user input, and a display 73 for displaying information related to the operation of the washing machine 1. The control panel 70 may provide a user interface for interaction between the user and the washing machine 1. The control panel 70 may be provided at various positions on the washing machine 1 in various forms depending on the design.

[0115] The controller 400 may obtain a washing mode selection input through the adjustment dial 71. The controller 400 may control the display 73 to display detailed options (e.g., water level, washing time, number of rinses, degree of spin drying) of the selected washing mode. The controller 400 may obtain an execution command for the selected washing mode via the start / stop button SP, and the controller 400 may perform an operation corresponding to the selected washing mode.

[0116] Detailed options of the washing mode may be set differently for each of the plurality of washing modes M. For example, for a washing mode that requires the use of the washing rod 120, the amount of laundry may be set relatively small, the water level may be set relatively high, the washing time may be set relatively short, and the operating speed of the motor 25 may be set relatively low. The operating speed of the motor 25 may refer to the rotation speed of the motor 25 and / or the number of direction changes of the motor 25.

[0117] When the amount of laundry is small, less friction may occur between the laundry, resulting in a decrease in washing efficiency. The washing rod 120 may be used to increase the friction applied to a small amount of laundry. The use of the washing rod 120 is suitable for washing a relatively small amount of laundry because when the washing rod 120 is installed, the loading space of the rotating tub 12 is reduced.

[0118] A high water level may be required in consideration of the length of the wash rod 120. The motor 25 may be set to a low operating speed to reduce damage to the laundry due to friction between the wash rod 120 and the laundry. Since the use of the wash rod 120 improves washing efficiency, a shorter washing time may be set.

[0119] In contrast, for a washing mode that does not require the use of the wash rod 120, the water level may be set relatively low, the washing time may be set relatively long, and the operating speed of the motor 25 may be set relatively high.

[0120] The controller 400 may control the control panel 70 to display at least one washing mode corresponding to the coupled state of the wash rod 120 or the separated state of the wash rod 120 from among the plurality of washing modes M. In addition, the controller 400 may control the control panel 70 to display guide information recommending the coupling or separation of the wash rod 120 through the display 73.

[0121] The display 73 may include various types of display panels. For example, the display 73 may include a liquid crystal display (LCD) panel, a light emitting diode (LED) panel, an organic LED (OLED) panel, or a micro LED panel. The display 73 may be used as an input device by including a touch screen.

[0122] The wash rod sensor 210 may detect the coupling or separation of the pulsator 110 and the wash rod 120. The wash rod sensor 210 may transmit a detection signal corresponding to the coupling or separation of the wash rod 120 to the controller 400. The controller 400 may recognize the coupling or separation of the pulsator 110 and the wash rod 120 based on the signal transmitted from the wash rod sensor 210.

[0123] Based on the pulsator 110 and the washing rod 120 being connected, the washing rod sensor 210 and the identifier 220 may contact each other or face each other at adjacent positions. Therefore, the washing rod sensor 210 may detect the identifier 220. The washing rod sensor 210 may send a detection signal corresponding to the connection of the pulsator 110 and the washing rod 120 to the controller 400. Based on the pulsator 110 and the washing rod 120 being separated, the washing rod sensor 210 may send an electrical signal corresponding to the separation of the pulsator 110 and the washing rod 120 to the controller 400.

[0124] The communication interface 300 can perform communication with an external device. For example, the communication interface 300 can support the establishment of a communication channel or a wireless communication channel between the external mobile device 2 or an external server (not shown), and can support communication through the established communication channel. The communication interface 300 can be implemented with various communication technologies. For example, the communication interface 300 may include a wireless communication module and / or a wired communication module. The wireless communication module may support wireless local area network (WLAN), home radio frequency (RF), infrared communication, ultra-wideband (UWB) communication, Wi-Fi, Wi-Fi Direct, Bluetooth, AD-HOC and / or Zigbee.

[0125] The external mobile device 2 may acquire a user input and transmit a control signal corresponding to the user input to the washing machine 1. The washing machine 1 may receive the control signal transmitted from the external mobile device 2 and perform an operation corresponding to the control signal. The external mobile device 2 may include an application for controlling the washing machine 1. The external mobile device 2 may display a graphical user interface (GUI) capable of controlling the washing machine 1. The user may operate the washing machine 1 using the external mobile device 2. The external mobile device 2 may transmit a control signal to the washing machine 1 based on the user input acquired after executing the application.

[0126] The controller 400 may include a processor 410 for generating a control signal for controlling the operation of the washing machine 1 and a memory 420 for storing programs, applications, instructions and data for controlling the operation of the washing machine 1. The processor 410 and the memory 420 may be implemented in separate semiconductor devices or in a single semiconductor device. In addition, the controller 400 may include a plurality of processors and a plurality of memories. The controller 400 may be disposed at various locations inside the washing machine 1. For example, the controller 400 may be included in a printed circuit board disposed inside the control panel 70.

[0127] The processor 410 may include an operation circuit, a memory circuit, and a control circuit. The processor 410 may include a single chip or multiple chips. In addition, the processor 410 may include a single core or multiple cores.

[0128] The processor 410 may process data and / or signals using a program provided from the memory 420, and transmit a control signal to each component of the washing machine 1 based on the processing result. For example, the processor 410 may obtain a user input through the control panel 70 or the communication interface 300. The processor 410 may output a control signal for controlling the motor 25, the water supply valve 18, and the drain valve 22 to perform operations according to the washing mode.

[0129] The memory 420 may store a program for performing operations according to the washing mode of the washing machine 1, and data including settings for operations performed according to the washing mode. The memory 420 may include a volatile memory (e.g., a static random access memory (SRAM) or a dynamic random access memory (DRAM)) and a nonvolatile memory (e.g., a read-only memory (ROM) or an erasable programmable read-only memory (EPROM)). The memory 420 may include a single memory device, or may include a plurality of memory devices.

[0130] As described above, the controller 400 may identify whether the pulsator 110 is coupled to the wash rod 120 based on the detection signal of the wash rod sensor 210. The controller 400 may control the control panel 70 to display at least one wash mode corresponding to the coupled state of the wash rod 120 or the separated state of the wash rod 120 among the plurality of wash modes M. The controller 400 may also control the communication interface 300 to transmit display information about at least one wash mode to the external mobile device 2.

[0131] For example, the controller 400 may control the control panel 70 to display at least one first washing mode requiring the use of the washing rod 120 in an identifiable manner based on the connection state of the washing rod 120. The controller 400 may control the control panel 70 to display other washing modes in addition to the at least one first washing mode requiring the use of the washing rod 120 in an identifiable manner based on the separation state of the washing rod 120.

[0132] In addition, in the connected state of the wash rod 120, the controller 400 may control the control panel 70 to display the first guide information recommending the separation of the wash rod 120 based on the second washing mode selected by the user input that does not require the use of the wash rod 120. In the separated state of the wash rod 120, the controller 400 may control the control panel 70 to display the second guide information recommending the connection of the wash rod 120 based on one of the at least one first washing modes that require the use of the wash rod 120 selected by the user input.

[0133] Meanwhile, the controller 400 may receive an execution command of a washing mode that can be executed both in the coupled state of the washing rod 120 and in the separated state of the washing rod 120 through the control panel 70 or the external mobile device 2. At least one washing mode corresponding to the coupled state of the washing rod 120 or the separated state of the washing rod 120 may include a washing mode that can be executed both in the coupled state of the washing rod 120 and in the separated state of the washing rod 120.

[0134] For example, the standard mode and the rinsing mode may be performed in the coupled state of the wash rod 120 or the separated state of the wash rod 120. Washing modes that can be performed in both the coupled state of the wash rod 120 and the separated state of the wash rod 120 may be set during design. Whether the wash rod 120 is coupled or not, the soaking mode, the dehydration mode, and the tub cleaning mode may be performed.

[0135] The controller 400 may detect the weight and / or amount of laundry contained in the rotary tub 12 based on input of an execution command of a washing mode executable both in the coupled state of the washing rod 120 and in the separated state of the washing rod 120. Various known methods may be used to detect the weight and / or amount of laundry.

[0136] The weight of the laundry can be divided into different levels. For example, when the maximum capacity of the washing machine 1 is 10 kg, the weight of the laundry can be divided into four levels. The first level can be defined as a light load, ranging from 0 kg to 2.5 kg. The second level can be defined as a medium load, ranging from 2.6 kg to 5 kg. The third level can be defined as a large load, ranging from 5.1 kg to 7.5 kg. The fourth level can be defined as a maximum load, ranging from 7.6 kg to 10 kg.

[0137] The controller 400 may control the control panel 70 to display first guide information recommending separation of the wash rod 120 or second guide information recommending connection of the wash rod 120 based on the weight of the laundry.

[0138] For example, the controller 400 may control the control panel 70 to display a first guide message recommending separation of the washing rod 120 based on the weight of the laundry detected in the coupled state of the washing rod 120 exceeding a predetermined reference level. The reference level may refer to a first level indicating a light load. The reference level may vary depending on the design. The weight of the laundry exceeding a predetermined reference level indicates that the amount of laundry is relatively large. In response to accommodating a large amount of laundry, a larger internal space of the rotating tub 12 may be ensured by removing the washing rod 120.

[0139] In addition, the controller 400 may control the control panel 70 to display the second guide information recommending the connection of the washing rod 120 based on the detected laundry weight being equal to or less than a predetermined reference level in the separated state of the washing rod 120. The laundry weight being equal to or less than the predetermined reference level indicates that the amount of laundry is relatively small. In response to accommodating a small amount of laundry, the washing efficiency may be improved by using the washing rod 120.

[0140] The user may also be provided with guidance information recommending separation or coupling of the wash rod 120 through the external mobile device 2. After the guidance information is provided, the user may input a confirmation command for separation or coupling of the wash rod 120 through the control panel 70 or the external mobile device 2. The controller 400 of the washing machine 1 may determine to separate or couple the wash rod 120 based on the input confirmation command.

[0141] Based on the determination of the separation or connection of the washing rod 120 according to the weight of the laundry, the controller 400 may control the motor 25 to rotate the rotating tub 12 to move the laundry to the side wall of the rotating tub 12. When the laundry is moved to the side wall of the rotating tub 12 by rotating the rotating tub 12 at a predetermined speed, the central space in the rotating tub 12 may be secured, and thus the user may connect or disconnect the washing rod 120 more easily.

[0142] After providing the guide information, the user may also input a cancel command for separating or coupling the wash rod 120. Based on the input of the cancel command for separating or coupling the wash rod 120, the controller 400 may operate the washing machine 1 according to the washing mode selected in the current state regardless of whether the wash rod 120 is coupled.

[0143] Meanwhile, the control panel 70 or the external mobile device 2 may provide a setting option for whether to provide guidance information on the separation or connection of the washing rod 120. The user may select whether to receive the guidance information. The user may operate the control panel 70 or the external mobile device 2 to activate or deactivate the providing function of the guidance information on the separation or connection of the washing rod 120. In response to the providing function of the guidance information being deactivated, the guidance information is not provided via the control panel 70 or the external mobile device 2.

[0144] Hereinafter, various embodiments of the control panel 70 that vary according to a user input and whether the pulsator 110 and the wash rod 120 are coupled are described.

[0145] Figure 8 A first embodiment of a control panel that varies according to user input and whether a pulsator is coupled to a wash rod is illustrated.

[0146] refer to Figure 8 Once the washing machine 1 is turned on or started, the controller 400 can identify the connection state or separation state of the pulsator 110 and the washing rod 120 based on the detection signal sent from the washing rod sensor 210.

[0147] In response to the pulsator 110 being coupled to the washing rod 120, the controller 400 of the washing machine 1 may control the control panel 70 to display at least one first washing mode requiring the use of the washing rod 120 in an identifiable manner. For example, the fifth mode, the sixth mode, and the seventh mode among the plurality of washing modes M may be included in the first washing mode set to require the use of the washing rod 120. The controller 400 of the washing machine 1 may control the control panel 70 so that the fifth mode, the sixth mode, and the seventh mode are illuminated. Therefore, the fifth mode, the sixth mode, and the seventh mode may be highlighted.

[0148] The fifth mode, the sixth mode and the seventh mode may represent a strong mode, a quick mode and a color clothes mode, respectively. The strong mode may be set to require the use of the washing rod 120 to wash clothes strongly. The quick mode may be set to require the use of the washing rod 120 to wash clothes quickly. The color clothes mode may be set to require the use of the washing rod 120 to effectively wash a small amount of color clothes.

[0149] In a state where the pulsator 110 is coupled to the washing rod 120 and the fifth mode, the sixth mode, and the seventh mode are highlighted, the user can select the fifth mode by rotating the adjustment dial 71. The indicator 72 that moves with the rotation of the adjustment dial 71 can light up at a position corresponding to the fifth mode. Therefore, the user can recognize that the fifth mode has been selected.

[0150] Since the fifth mode suitable for the coupled state of the wash rod 120 has been selected, the display 73 of the control panel 70 may display information about the fifth mode (eg, water level, washing time, number of rinsing, degree of spin drying).

[0151] The control panel 70 may be controlled to allow the user to select other washing modes in addition to the fifth mode, the sixth mode, and the seventh mode highlighted in response to the connection state of the washing rod 120. For example, the user may select the third mode by operating the adjustment dial 71 while the fifth mode, the sixth mode, and the seventh mode are highlighted.

[0152] In other words, even if the fifth mode, the sixth mode, and the seventh mode are highlighted, the user may select any other desired washing mode, that is, the user's selection may not be limited to one of the highlighted fifth mode, sixth mode, and seventh mode.

[0153] In another embodiment, the control panel 70 may be controlled so that only the fifth mode, the sixth mode, and the seventh mode corresponding to the connection state of the washing rod 120 are selectable, that is, the fifth mode, the sixth mode, and the seventh mode are activated, and other washing modes are deactivated. The deactivated washing mode may be temporarily set to be unselectable. The user may also activate all washing modes by pressing a separate button (e.g., a start / stop button).

[0154] Fig. 9 A second embodiment of a control panel that varies based on user input and whether a pulsator is coupled to a wash rod is illustrated.

[0155] refer to Fig. 9 In a state where the pulsator 110 is coupled to the washing rod 120, a second washing mode that does not require the use of the washing rod 120 may be selected by user input. For example, the second mode, the third mode, and the fourth mode among the plurality of washing modes M may be included in the second washing mode set to require not using the washing rod 120.

[0156] The second mode, the third mode and the fourth mode can represent a gentle mode, a large capacity mode and a water saving mode respectively. The gentle mode can be set to require not using the washing rod 120 in order to minimize the damage to delicate clothes such as underwear. The large capacity mode of the washing machine can be set to require not using the washing rod 120 because a large amount of loading space is required. The large capacity mode can include a bedding mode and a blanket mode. The water saving mode can be set to require not using the washing rod 120 in order to use the least water.

[0157] In a state where the fifth mode, the sixth mode, and the seventh mode are highlighted in response to the connection state of the pulsator 110 and the washing rod 120, the user can rotate the adjustment disk 71 to select the third mode. The indicator 72 that moves with the rotation of the adjustment disk 71 can light up at a position corresponding to the third mode. Therefore, the user can recognize that the third mode has been selected. Information about the selected third mode can be displayed on the control panel 70.

[0158] In the current state that the pulsator 110 and the washing rod 120 are coupled, it is inappropriate to apply the third mode that does not require the use of the washing rod 120. Therefore, preferably, the user is guided to separate the washing rod 120. That is, in response to selecting the second washing mode that does not require the use of the washing rod 120 in the coupled state of the washing rod 120, the controller 400 may control the control panel 70 to display the first guide information recommending the separation of the washing rod 120.

[0159] The user may input a confirmation command for separating the wash rod 120 through the control panel 70 or the external mobile device 2. Based on the input of the confirmation command for separating the wash rod 120, the washing machine 1 may be in a standby state until the wash rod 120 is separated from the pulsator 110.

[0160] Unlike the second to seventh modes described above, the first mode and the eighth to twelfth modes may be set to be executed both in the coupled state of the washing rod 120 and in the separated state of the washing rod 120. For example, the first mode and the eighth to twelfth modes may include a standard mode, a rinsing mode, a soaking mode, a dehydration mode, and a tub cleaning mode. Whether the washing rod 120 is used in the first mode and the eighth to twelfth modes may depend on the weight of the laundry.

[0161] When the user selects one of the first mode and the eighth to twelfth modes and inputs an execution command, first guidance information recommending separation of the washing rod 120 or second guidance information recommending connection of the washing rod 120 may be provided according to the weight of the laundry. The user may input a confirmation command or a cancellation command for separating or connecting the washing rod 120. The controller 400 may control the motor 25 to rotate the rotating tub 12 based on the confirmation command. Based on the cancellation command, the controller 400 may operate the washing machine 1 according to the washing mode selected in the current state, regardless of whether the washing rod 120 is connected.

[0162] The washing modes that require or do not use the washing rod 120 are not limited to those described above. The washing modes can be changed according to the design. For example, in contrast to the above, the second mode, the third mode, and the fourth mode can be set to require the use of the washing rod 120, and the fifth mode, the sixth mode, and the seventh mode can be set to not require the use of the washing rod 120.

[0163] Fig.10 A third embodiment of a control panel that varies according to user input and whether a pulsator is coupled to a wash rod is illustrated.

[0164] refer to Fig.10 In a state where the pulsator 110 and the washing rod 120 are separated, the control panel 70 may display other washing modes in an identifiable manner except for at least one washing mode requiring the use of the washing rod 120. For example, other washing modes except for the fifth mode, the sixth mode, and the seventh mode set to require the use of the washing rod 120 may be highlighted.

[0165] In a state where the pulsator 110 is separated from the washing rod 120, one of the at least one washing modes that require the use of the washing rod 120 may be selected by user input. For example, the fifth mode may be selected by selection of the adjustment dial 71. In this case, the controller 400 may control the control panel 70 to display second guidance information that recommends coupling the washing rod 120. Information about the selected fifth mode may also be displayed on the control panel 70.

[0166] In the current state that the pulsator 110 is separated from the washing rod 120, it is inappropriate to apply a washing mode requiring the use of the washing rod 120. Therefore, it is preferred that the user is guided to perform the coupling of the washing rod 120.

[0167] The user may input a confirmation command for coupling the wash rod 120 through the control panel 70 or the external mobile device 2. Based on the input of the confirmation command for coupling the wash rod 120, the washing machine 1 may be in a standby state until the wash rod 120 is coupled to the pulsator 110.

[0168] As another example, in a state where the pulsator 110 and the washing rod 120 are separated and other washing modes except the fifth mode, the sixth mode, and the seventh mode are highlighted, a third mode that does not require the use of the washing rod 120 may be selected.
