[0040] This application provides a display device. The display device can be used in household appliances.

[0041] This application provides a household appliance, including a housing and a display device according to any embodiment of this application. The display device is disposed in the housing, meaning that the user can see the display device.

[0042] There are no restrictions on the type of household appliances; for example, they can be cooking appliances, clothing processing equipment, etc.

[0043] In this application embodiment, a household appliance is used as an example to describe a clothing processing device. The clothing processing device includes a housing, a door assembly, a clothing processing drum, a control motherboard, and a display device in any embodiment of this application.

[0044] The garment handling drum is rotatably mounted inside the housing. The garment handling drum has a garment handling chamber. The housing also has a garment loading / unloading port communicating with the garment handling chamber, and a door assembly is used to open or close the garment loading / unloading port.

[0045] Of course, clothing treatment equipment can also be equipped with an electrolysis component to electrolyze and sterilize the water used for washing and caring for clothes, thereby achieving sterilization and colorfastness prevention.

[0046] The garment treatment equipment can also be equipped with a steam unit for deodorizing, wrinkle removal and other care of garments.

[0047] The control motherboard is used to control the operation of the entire machine.

[0048] Please see Figures 1 to 3 The display device includes a first display unit 2 and a knob assembly 1.

[0049] The first display section 2 extends along a first direction. The knob assembly 1 is arranged adjacent to the first display section 2 in the first direction. That is, the knob operation section 10 is provided at one end of the first display section 2 in the first direction.

[0050] It should be noted that, taking the first direction as the left and right direction of the household appliance as an example, the knob assembly 1 can be located on the right side of the first display unit 2 or on the left side of the first display unit 2.

[0051] Please continue reading. Figures 1 to 3 The knob assembly 1 includes a knob operation section 10 and a second display section 11 disposed radially inside the knob operation section 10. That is, the second display section 11 is located radially inside the knob operation section 10, and the first display section 2 is located radially outside the knob operation section 10. In this way, the second display section 11 can fully utilize the space radially inside the knob operation section 10 to display an image, which helps to improve the compactness of the display device's structural layout.

[0052] Furthermore, since the knob assembly 1 and the first display unit 2 are arranged adjacent to each other in the first direction, it is beneficial to make the screens of the first display unit 2 and the second display unit 11 form a unified visual effect.

[0053] For example, the first display unit 2 can also be used to play dynamic images (i.e., animations).

[0054] The type of the first display unit 2 is not limited. For example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0055] Exemplarily, the second display unit 11 can also be used to play dynamic pictures (i.e., animations).

[0056] The type of the second display unit 11 is not limited. For example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0057] It should be noted that, please refer to Figure 7 , the knob operation part 10 has an appropriate extension length in the direction of its rotation axis, which is convenient for the user to hold. That is, the knob operation part 10 is generally cylindrical. The circumferential outer surface in a circular ring shape is used for the user to hold.

[0058] Exemplarily, please refer to Figure 1 , the dimension D1 of the first display unit 2 in the second direction is not less than the dimension D2 of the second display unit 11 in the second direction, and not greater than the outer diameter D3 of the knob operation part 10; wherein, the first direction and the second direction are perpendicular. That is, D2≤D1≤D3. It should be noted that, D2, D1, and D3 are not equal at the same time. For example, when D2 = D1, D1 < D3; when D3 = D1, D2 < D1. In this embodiment, the outer diameter of the knob operation part 10 can be set to a size suitable for holding, and the display size of the second display unit 11 in the second direction is between the size of the second display unit 11 in the second direction and the outer diameter of the knob operation part 10. Thus, the second display unit 11 has a suitable size to match the knob operation part 10, and the overall size is more in line with ergonomics, which is beneficial to improving the overall layout rationality and visual effect of the display device.

[0059] Exemplarily, the second display unit 11 is circular, and the second display unit 11 and the knob operation part 10 are concentrically arranged. Thus, the shapes of the second display unit 11 and the knob operation part 10 can be better matched, the visual effect is better, and the space utilization rate is better.

[0060] Exemplarily, the outer diameter D2 of the second display unit 11 is 1 / 3 to 2 / 3 of the outer diameter D3 of the knob operation part 10. That is, D3*1 / 3≤D2≤D3*2 / 3. The size ratio of the second display unit 11 and the knob operation part 10 is relatively moderate and reasonable. When the size of the knob operation part 10 is convenient for the user to hold, the first display unit 2 has a suitable area to display the picture.

[0061] In some specific embodiments, D3*1 / 2≤D2≤D3*2 / 3, and the second display unit 11 has a larger area to display the screen.

[0062] For example, please refer to Figures 1 to 4 , Figure 6 The knob assembly 1 also includes an indicator light ring 12, which is located radially inside the knob operating portion 10 and surrounds the outer periphery of the second display portion 11. That is, radially, the indicator light ring 12 is located between the knob operating portion 10 and the first display portion 2. The indicator light ring 12 illuminates when the household appliance is turned on, enhancing the visual effect of the display device.

[0063] Since the indicator light ring 12 is located between the first display section 2 and the knob operation section 10, please refer to... Figure 6 When the first display unit 2 displays a screen, the light from the indicator ring 12 can provide a visual transition between the first display unit 2 and the knob operation unit 10, and also helps to improve the layout rationality of the knob assembly 1.

[0064] Indicator ring 12 refers to the area used to display a ring of light. In other words, the user can see indicator ring 12.

[0065] For example, please refer to Figure 6 The indicator light ring 12 and the knob operation part 10 are arranged radially at a distance from each other on the knob operation part 10, and the interval area between the indicator light ring 12 and the knob operation part 10 is a non-display area.

[0066] For example, please refer to Figure 6 The indicator light ring 12 and the first display part 2 are arranged radially at a distance from each other in the knob operation part 10, and the interval area between the indicator light ring 12 and the first display part 2 is a non-display area.

[0067] For example, please refer to Figure 5 When the knob assembly 1 is in the off or standby state, the non-display area and the first display section 2 display approximately the same color, for example, both are black. This improves the consistency of appearance when the device is off or in standby state.

[0068] For example, please refer to Figure 1 The dimension D1 of the first display unit 2 in the second direction does not exceed the outer diameter D4 of the indicator ring 12. Thus, the outer diameter of the indicator ring 12 is relatively large, resulting in a better visual transition effect.

[0069] For example, please refer to Figures 2 to 4 , Figure 6The first display unit 2 is used to display a first interface, which includes multiple selectable function items. It should be noted that the first display unit 2 can display the first interface at any time, and can display different interfaces under different conditions.

[0070] Functional items can be displayed in text and / or graphic form; there are no restrictions on this. For example, please refer to... Figures 2 to 4 , Figure 6 In some specific implementations, functional items are displayed in text form.

[0071] The specific content of the functional items on the first interface can be set according to the functions of home appliances.

[0072] For garment processing equipment, the functional items are the main washing and care programs. These may include, for example, color protection wash, mixed wash, wool wash, anti-color bleeding wash, down jacket wash, bath towel wash, plush wash, steam wash, and mixed wash. It should be noted that different main washing and care programs differ in at least one aspect, such as the rotation speed of the garment drum, temperature, water volume, and washing duration, to allow for the use of different washing and care parameters based on the different materials of the garments.

[0073] It should be noted that not all functions of a home appliance need to be displayed on the first screen at the same time. For example, if a laundry detergent has seven main programs, but fewer than seven functions are displayed on the first screen at any given time, the remaining functions can be displayed on the first screen as needed using a loop.

[0074] For example, the display device includes a control unit, which responds to a selection command to select one of a plurality of function items on a first interface, causing the second display unit 11 to display the selected function item. In this embodiment, the user can intuitively see the function items to be selected on the first interface and can see the currently selected function item on the second display unit 11, which facilitates a prominent prompt to the user; in addition, the interaction between the first display unit 2 and the second display unit 11 is enhanced, which is beneficial to improving the user experience.

[0075] For example, please see Figure 2 The first interface displays four function items: color protection wash, mixed, wool, and anti-bleeding wash. If you select the color protection wash function, please refer to [link / reference]. Figure 3If the color-protecting wash function item leaves the first display unit 2, that is, the first interface of the first display unit 2 does not display the color-protecting wash function item, and the color-protecting wash function item jumps to the second display unit 11 for display. It should be noted that when the color-protecting wash function item leaves the first display unit 2, other function items not displayed on the first interface can be added to the first interface, such as the aforementioned wool or steam wash function items can be added to the first interface. That is, from Figure 2 The display status shown has switched to Figure 3 The display status is shown below.

[0076] It should be noted that the first display unit 2 displays the function items to be selected, and the second display unit 11 displays the currently selected function item. When the home appliance is started (i.e. when the start command is entered), the program corresponding to the currently selected function item displayed on the second display unit 11 is executed, and the program corresponding to the function items to be selected on the first display unit 2 is not executed.

[0077] The control unit is used to operate the screens of the first display unit 2 and the second display unit 11. For example, in some embodiments, the control unit may include a first circuit board and a second circuit board, wherein the first circuit board is used to operate the screens of the first display unit 2 and the second circuit board is used to operate the screens of the second display unit 11.

[0078] It should be noted that the first circuit board (or the second circuit board) includes not only the rigid board, but also the circuits, electronic components, etc. integrated on the rigid board.

[0079] For example, the first circuit board and the second circuit board are electrically connected, meaning there is information interaction between them, allowing the first display unit 2 and the second display unit 11 to collaboratively display the screen. For example, while the control unit, according to a selection command, causes the second display unit 11 to display the selected function item, the first display unit 2 displays the remaining function items besides the selected one. This allows the user to intuitively see which function items are available for selection besides the currently selected one, facilitating user operation if a reselection is needed.

[0080] For example, when the first display unit 2 displays all function items except the selected function item, and the second display unit 11 displays the selected function item, the control unit is further configured to control the first display unit 2 and / or the second display unit 11 to switch display interfaces according to the start command of the home appliance. It should be noted that the start command of the home appliance refers to the start command that initiates the execution of the program corresponding to the function item. That is, when the second display unit 11 displays the currently selected function item, and the first display unit 2 displays the remaining function items, the home appliance can directly start the program corresponding to the currently selected function item displayed on the second display unit 11, making operation simple.

[0081] For example, if the second display unit 11 displays the color-protecting wash function and the first display unit 2 displays the other function items, and the user inputs a start command, the garment handling equipment will begin executing the washing and care program corresponding to the color-protecting wash function. At this time, the first display unit 2 and / or the second display unit 11 switch interfaces. For example, the first display unit 2 switches to an interface related to the color-protecting wash function, such as an interface displaying the washing and care progress of the color-protecting wash function. The second display unit 11 can also switch interfaces.

[0082] There are no restrictions on how input selection commands can be made. For example, it can be input remotely (such as through a mobile app or a remote control), input via buttons, or voice input.

[0083] For example, in some embodiments, the knob assembly includes a rotation detection unit for detecting the rotation of the knob operation unit to input a selection command, i.e., the user can input a selection command by rotating the knob operation unit 10. Specifically, the rotation angle of the knob operation unit 10 can be detected by the rotation detection unit, and the rotation angle of the knob operation unit 10 is associated with the function items on the first interface, so the selection command can be input based on the rotation angle of the knob operation unit 10. For example, every time the knob operation unit 10 rotates 30°, one function item on the first interface jumps to the second display unit 11 for display, and when the knob operation unit 10 rotates another 30°, another function item jumps to the second display unit 11 for display. If the knob operation unit 10 rotates 60° continuously, the second display unit 11 displays two function items sequentially, presenting a scrolling display effect; it can be understood that if the knob operation unit 10 rotates 60° continuously at a very fast speed, the second display unit 11 may not have time to display the first selected function item, and directly displays the second selected function item.

[0084] In other embodiments, the first display unit 2 includes a first touch-sensitive detection unit, which inputs a selection command by detecting operations such as tapping on a function item on the first interface or dragging the first interface on the first display unit 2. Specifically, for example, when a user slides or clicks on the surface of the first touch-sensitive detection unit, the function item on the first interface of the first display unit 2 can move, and the movement effect of the function item is related to the sliding distance or the number of clicks.

[0085] The first touch-sensitive detection unit can be a designated area on the first interface, or the entire first interface can be used as the first touch-sensitive detection unit. For example, the first display unit 2 is a touch screen as a whole.

[0086] In some embodiments, the second display unit 11 includes a second touch-sensitive detection unit, which inputs a selection command by detecting a sliding operation or a clicking operation performed on the second touch-sensitive detection unit.

[0087] The working principles of the first and second touch-sensitive detection units are the same, and will not be elaborated here.

[0088] For example, multiple function items on the first interface are arranged along a first direction. The multiple function items on the first interface are used to move synchronously along the first direction when a selection command is input, and the first function item located in the movement direction is jumped to the second display unit 11 for display.

[0089] It should be noted that the function items can move continuously or in jumps on the first interface. For example, taking the function items of the aforementioned garment processing equipment as an example, if the first interface displays four function items, sequentially from the direction closest to the knob assembly 1 to the direction furthest from the knob assembly 1: Color Protection Wash, Mixed Wash, Wool Wash, and Anti-Color Bleeding Wash. When the first touch-sensitive detection unit is clicked for the first time, all four function items move synchronously towards the knob assembly 1, and the Color Protection Wash function item leaves the first display unit 2 and jumps to the second display unit 11 for display. If the first touch-sensitive detection unit is clicked a second time, the Mixed Wash function item leaves the first display unit 2 and jumps to the second display unit 11 for display. At this time, the second display unit 11 displays the Mixed Wash function item and does not display the Color Protection Wash function item. That is to say, when the next function item jumps to the second display unit 11 for display, it will automatically overwrite the function item previously displayed on the second display unit 11, and so on.

[0090] It should be noted that when the color protection wash function item leaves the first display unit 2, the next function item can be added and displayed on the first display unit 2.

[0091] For example, please refer to Figures 2 to 4 , Figure 6The first interface includes multiple graphic sub-areas 2a arranged along a first direction. Each graphic sub-area 2a is used to display a function item. The multiple function items on the first interface are used to jump synchronously among the multiple graphic sub-areas 2a when a selection command is input, and the position of the graphic sub-areas 2a remains unchanged.

[0092] For example, graphic sub-region 2a is circular.

[0093] For example, please see Figure 2 The first interface displays four graphic sub-areas side-by-side (2a). The color-protecting wash function is displayed in the first graphic sub-area (2a), the mixed function function in the second graphic sub-area (2a), the wool function function in the third graphic sub-area (2a), and the anti-color bleeding function function in the fourth graphic sub-area (2a). Please refer to [link / reference] when you first navigate to the interface. Figure 2 The color-protecting wash function jumps from the first graphic sub-area 2a to the second display section 11; the mixed function jumps from the second graphic sub-area 2a to the first graphic sub-area 2a; the wool function jumps from the third graphic sub-area 2a to the second graphic sub-area 2a; the anti-color bleeding function jumps from the fourth graphic sub-area 2a to the third graphic sub-area 2a; simultaneously, the down jacket function is displayed in the fourth graphic sub-area 2a, i.e., from... Figure 2 The displayed status has switched to Figure 3 The displayed status is shown below. Similarly, the next selection command input will start from... Figure 3 The displayed status has switched to Figure 4 The status is shown below.

[0094] For example, the various graphic sub-regions have the same shape and the same area.

[0095] Of course, in other embodiments, the area of ​​some graphic sub-regions may be larger than the area of ​​the other graphic sub-regions.

[0096] For example, the area of ​​the second display unit 11 is larger than the area of ​​any graphic sub-area 2a. Thus, when the function item icon jumps to the second display unit 11, it has the effect of enlarging the screen and highlighting key points.

[0097] It should be noted that the names of the functional items in the above embodiments of this application are described using a washing machine as an example. The clothing processing device in the embodiments of this application can also be a dryer or a washer-dryer combo. For different types or models of clothing processing devices, the names of the functional items are adaptively varied according to the main program required by the clothing processing device. For example, the functional items for a dryer can be steam washing, quick drying, odor removal, etc., and there is no limitation here.

[0098] For example, please refer to Figures 2 to 4 , Figure 6 The display device also includes a third display unit 3.

[0099] The third display unit 3 is provided with a switch operation area 3A, and / or, the third display unit 3 is provided with a start / stop operation area 3B.

[0100] The switch operation area 3A detects pressing operations applied to it to input power-on or power-off commands for household appliances. The switch operation area 3A can also be understood as the on / off switch for the household appliance, also known as the power button.

[0101] The start / stop operation area 3B detects press operations applied to it to input start / stop commands for home appliances. The start / stop operation area 3B can also be referred to as the pause button.

[0102] In this way, the power button and pause button can be integrated into the display device, improving the integration level of the display device.

[0103] For example, an on / off switch indicator is also present in the location of the switch operation area 3A. An on / off switch indicator is also present in the location of the start / stop operation area 3B; please refer to [link / reference]. Figure 5 Even when the third display unit 3 is off, the power button and start / stop button indicators can still be identified, allowing users to quickly locate the power switch area 3A and the start / stop operation area 3B for easier operation. Of course, the power button and start / stop button indicators can also be identified when the third display unit 3 is in display mode.

[0104] For example, the third display unit 3, the first display unit 2, and the second display unit 11 are arranged adjacent to each other in the first direction, with the second display unit 11 located between the first display unit 2 and the third display unit 3. Thus, the third display unit 3, the first display unit 2, and the second display unit 11 are arranged in a generally elongated shape in the first direction. For example, arranging them in an elongated shape along the left-right direction on the front surface of a household appliance is beneficial for presenting an overall elongated visual display effect.

[0105] It should be noted that the first display unit 2, the second display unit 11, and the third display unit 3 mentioned above refer to areas that can be displayed visually (observed by the user).

[0106] For example, the first display unit 2 and the third display unit 3 have the same size in the second direction. This makes the visual coordination between the first display unit 2 and the third display unit 3 better.

[0107] For example, please refer to Figure 1 The size W1 of the first display unit 2 in the first direction is larger than the size W2 of the third display unit 3 in the first direction. The size of the third display unit 3 in the first direction is relatively shorter, so that a larger size can be left for the first display unit 2 to display the image without changing the installation space of the household appliance.

[0108] For example, the outlines of the first display unit 2 and the third display unit 3 are generally rectangular, but it should be noted that the long side of the rectangle is discontinuous and is broken at the knob assembly 1.

[0109] For example, please refer to Figure 7 The display device includes a mounting bracket 33 and a panel assembly 31. The mounting bracket 33 provides mounting support for other components of the display device, and the panel assembly 31 is disposed on the first side of the mounting bracket 33. The panel assembly 31 is generally flat, and when the display device is installed on the household appliance, the panel assembly 31 serves as the exterior surface of the display device and also constitutes part of the exterior surface of the household appliance.

[0110] For example, please refer to Figure 7 and Figure 9 The display device includes a first display screen 34, which is disposed between the mounting bracket 33 and the panel assembly 31. The first display screen 34 integrates display and circuit driving components; that is, the aforementioned first circuit board also constitutes part of the first display screen 34. The panel assembly 31 provides protection for the first display screen 34.

[0111] It should be noted that the area of ​​the panel assembly 31 used for display is a light-transmitting part, while another part can be light-shielded. The panel assembly 31 can transmit the display image of the first display screen 34 while also blocking other surrounding structures. For example, a touch sensor and circuit layer can be provided on the panel assembly 31 to realize touch control. That is to say, the display area defined by a part of the panel assembly 31 and the first display screen 34 can be understood as the aforementioned first display part 2.

[0112] The panel assembly 31 can protect the first display screen 34.

[0113] It should be noted that the area of ​​the panel assembly 31 used for display is the light-transmitting part, while another part can be light-shielded. The panel assembly 31 can transmit the display image of the second display screen 11" while also blocking other surrounding structures. For example, a touch sensor and circuit layer can be provided on the panel assembly 31 to realize touch control. That is to say, the display area defined by a part of the panel assembly 31 and the second display screen 11" can be understood as the aforementioned second display part 11.

[0114] For example, please refer to Figure 9The knob assembly 1 includes a support structure 13, a second display screen 11", and an end cap 14. The support structure 13 is connected to the end cap 14. The knob operating part 10 surrounds the outer periphery of the support structure 13 and can rotate relative to the support structure 13. The end cap 14 is located radially inside the knob operating part 10 and is disposed on the axial side of the support structure 13 on the knob operating part 10. The second display screen 11" is disposed between the end cap 14 and the support structure 13.

[0115] For example, the mounting bracket 33 has a through hole 33b, through which a portion of the structure of the knob assembly 1 passes.

[0116] For example, please refer to Figure 7 and Figure 9 The mounting bracket 33 has a lamp cavity 33a, and the display device also includes an RGB lamp group 32. The RGB lamp group 32 is disposed in the lamp cavity 33a, and the panel assembly 31 at least covers the lamp cavity 33a. The light from the RGB lamp group 32 acts on the panel assembly 31, so that a portion of the panel assembly 31 defines the third display unit 3. The working principle of the RGB lamps is to change the brightness by controlling the current of the red, green, and blue lamps, thereby achieving a color effect through different color combinations. In other words, the third display unit 3 does not need a screen; it only needs to display the corresponding colors, without needing to present animations or other visuals. This helps to reduce the cost of the third display unit 3.

[0117] The panel assembly 31 is provided with a switch touch sensor, and / or the panel assembly 31 is provided with a start / stop touch sensor.

[0118] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0119] It is understood that the area occupied by the switch touch sensor on the panel assembly 31 can be understood as the aforementioned switch operation area 3A. The area occupied by the start / stop touch sensor on the panel assembly 31 can be understood as the aforementioned start / stop operation area 3B.

[0120] For example, please refer to Figure 7 The display device also includes a light-diffusing sheet 35, which is disposed between the light-emitting side of the lamp group and the corresponding panel assembly 31. The light-diffusing sheet 35 is used to perform light-diffusing processing to make the light more uniform and softer.

[0121] This application provides a display control method. This display control method can be applied to the display devices described in any of the above embodiments.

[0122] In some embodiments, please refer to Figure 10 The display control method includes the following steps S1 and S2.

[0123] S1. The first display unit 2 displays a first interface, which includes multiple selectable function items arranged along a first direction.

[0124] S2. In response to a selection instruction that selects one of the multiple function items on the first interface, the second display unit 11 displays the selected function item.

[0125] In this embodiment, the user can intuitively see the selectable function items on the first interface and the currently selected function item on the second display unit 11. In addition, the interaction between the first display unit 2 and the second display unit 11 is enhanced, which helps to improve the user experience.

[0126] For example, the display control method includes: when the second display unit 11 displays the selected function item, the first display unit 2 displays the remaining function items other than the selected function item.

[0127] This allows users to intuitively see which other features are available besides the currently selected one, making it easier for them to make a new selection if needed.

[0128] For example, the steps described above, which involve displaying the selected function item on the second display unit 11 and displaying the remaining function items on the first display unit 2, include: moving multiple function items arranged along a first direction on the first interface synchronously along the first direction, and transferring the first function item located in the direction of movement to the second display unit 11 for display. This facilitates a better dynamic interactive effect for the multiple function items on the first interface.

[0129] For example, the display control method further includes: when the selected function item is displayed on the second display unit 11, coordinating the background image of the first display unit 2 with the background image of the second display unit 11. This further enhances the overall visual appeal of the first display unit 2 and the second display unit 11, resulting in a better visual effect.

[0130] In this embodiment, the background image includes at least one of color, pattern coherence, and animation coherence.

[0131] For example, when both the second display unit 11 and the first display unit 2 are displaying animations, the first display unit 2 and the second display unit 11 play continuous animations. Specifically, the animation on the first display unit 2 extends to the second display unit 11.

[0132] It should be noted that when the first interface has the aforementioned graphic sub-area 2a, the display area outside the graphic sub-area 2a belongs to the background screen, while the area inside the graphic sub-area 2a does not belong to the background screen.

[0133] For example, please see Figure 6 The background colors of the first display unit 11 and the second display unit 2 are both black, and the background colors of the first display unit 11 and the second display unit 2 play the animation in harmony.

[0134] The following description uses the working process of a garment processing device as an example.

[0135] It should be noted that in standby mode, please refer to [link / reference]. Figure 5 The first display unit 2, the second display unit 11, and the third display unit 3 will not display anything, and the overall display will appear mostly black. The power button and start / stop button markings on the third display unit 3 are visible.

[0136] Press the switch on operating area 3A to turn on the garment processing equipment.

[0137] After powering on, the first display unit 2 and the second display unit 11 display their respective boot screens. The third display unit 3 lights up and displays the corresponding color. The boot screen can be an animated display or a static image.

[0138] Please see Figure 6 The second display unit 11 displays default function items on its startup screen. The startup screen of the first display unit 2 is not limited and may include the aforementioned first screen; that is, multiple function options appear on the startup screen of the first display unit 2. Alternatively, the startup screen of the first display unit 2 may not be the first screen, meaning that multiple function options do not appear on the startup screen of the first display unit 2. In this case, if the first screen needs to be displayed, the first screen can be activated by rotating the knob 10 in any direction, touching the first display unit 2, or touching the second display unit 11, thus switching the first display unit 2 from the startup screen to the first screen.

[0139] If the user wants the garment processing device to use the default function on the second display unit 11 for washing and care, they can directly press the start / stop operation area 3B, and the garment processing device will enter the washing and care program corresponding to the default function. If the user wants a specific function on the first display unit 2, they can rotate the knob operation unit 10, or slide or click on the first display unit 2, or slide or click on the second display unit 11, until the desired function is displayed on the second display unit 11. At this time, the remaining functions will still be displayed on the first interface of the first display unit 2.
