[0047] This application provides a display device. The display device can be used in household appliances.

[0048] 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.

[0049] There are no restrictions on the type of household appliances; for example, they can be cooking appliances, clothing processing equipment, etc.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The garment treatment equipment can also be equipped with a steam unit for deodorizing, wrinkle removal and other care of garments.

[0054] The control motherboard is used to control the operation of the entire machine.

[0055] Please see Figures 1 to 4 The display device includes a first display unit 2, a second display unit 11, and a control unit.

[0056] The 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. For example, the second display unit can display the selected function item and / or other parameters matching the function item.

[0057] For example, the first display unit 2 can also be used to play dynamic images or display images or pictures that match the selected function items.

[0058] For example, the second display unit 11 can also be used to play dynamic images or display images or pictures that match the selected function items.

[0059] 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 5 , Figures 6 to 8 In some specific implementations, functional items are displayed in text form.

[0060] The specific content of the functional items on the first interface can be set according to the functions of home appliances.

[0061] For garment processing equipment, the functional items are the main washing and care programs. These may include, for example, color protection wash, silk, wool, colorfastness protection, down jacket, bath towel, plush, steam wash, and silk 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.

[0062] 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.

[0063] The control unit is used to operate the functions or 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 screen of the first display unit 2 and the second circuit board is used to operate the screen of the second display unit 11.

[0064] 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.

[0065] For example, the first circuit board and the second circuit board are electrically connected, that is, there is information interaction between the first circuit board and the second circuit board, so that the first display unit 2 and the second display unit 11 can display the screen together.

[0066] The control unit is used to synchronously move multiple function items on the first interface based on selection commands, and to move one or more of these function items from the first display unit 2 to the second display unit 11 along the movement direction. The second display unit 11 is used to display the currently selected function item. It should be noted that the selection command can be implemented by clicking on a function item on the first display unit or dragging the interface of the first display unit, or it can be implemented through the second display unit; no specific limitation is made here. It should also be noted that the phrase "one or more of the multiple function items move from the first display unit 2 to the second display unit 11 along the movement direction" means that if a single input selection command only moves one function item from the first display unit 2 to the second display unit 11, then only one function item leaves the first display unit 2 and moves to the second display unit 11. If a single input selection command moves multiple function items from the first display unit 2 to the second display unit 11, the multiple function items sequentially leave the first display unit 2 and are sequentially displayed on the second display unit 11. However, since the multiple function items are displayed sequentially on the second display unit 11, when a later function item moves to the second display unit 11, the previous function item will leave the second display unit 11. For example, please refer to... Figure 2 The first interface displays four function items: color protection wash, silk, wool, and anti-color bleeding. 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, meaning the first interface of the first display unit 2 does not display the color-protecting wash function item, it moves 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; for example, the aforementioned quick wash function item 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.

[0067] 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.

[0068] In related technologies, when the function item on the first display unit 2 needs to be selected by moving the selection icon to the corresponding candidate function item, a further confirmation operation is required before the selected function item can be displayed on the second display unit 11, which is cumbersome.

[0069] In this embodiment, when a function item on the first interface of the first display unit 2 is moved to the second display unit 11 for display, it becomes the currently selected function item, which is convenient to operate.

[0070] The display device of this application embodiment allows the user to intuitively see the selectable function items on the first interface and the currently selected function item on the second display unit 11, facilitating a prominent prompt to the user. Furthermore, it enhances the interaction between the first display unit 2 and the second display unit 11, improving the user experience. In addition, inputting a selection command allows multiple function items on the first interface to move synchronously, for example, along a straight path or a curved path, creating an overall sliding effect, resulting in better visual appeal and human-computer interaction.

[0071] It should be noted that the movement in the embodiments of this application refers to the visual movement of functional items. The display content of the second display unit 11 is visually connected with the content of the first display unit 2, and the physical structure and position of the second display unit 11 and the first display unit 2 remain unchanged.

[0072] For example, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 8The control unit is also configured to, when the first function item in the direction of movement moves from the first display unit 2 to the second display unit 11, cause the first display unit 2 to display the remaining function items besides the selected function item. This allows the user to intuitively see which function items are available for selection besides the currently selected function item, facilitating user operation if a reselection is needed.

[0073] For example, the first display unit 2 and the second display unit 11 are arranged along a first direction, and multiple function items move synchronously along the first direction according to the input selection command. For example, the second display unit 11 is located at the first end of the first display unit 2 in the first direction, and the synchronous movement of multiple function items along the first direction may be towards the second display unit 11 or away from the second display unit 11.

[0074] It should be noted that, taking the first direction as the left-right direction of the household appliance as an example, the second display unit 11 can be located to the right of the first display unit 2 or to the left of the first display unit 2.

[0075] In some embodiments, multiple functional items can only move synchronously in a first direction and towards the second display unit 11, and cannot move synchronously in a direction away from the second display unit 11. In other embodiments, multiple functional items can only move synchronously in a first direction and away from the second display unit 11, and cannot move synchronously towards the second display unit 11. In still other embodiments, depending on the direction of the selection instruction, multiple functional items can move synchronously in both the first direction and towards the second display unit 11, and also synchronously in a direction away from the second display unit 11.

[0076] It should be noted that before the function items on the first interface are moved to the second display unit 11, the interface displayed on the second display unit 11 is not limited. For example, the startup interface of the second display unit 11 may include a default function item.

[0077] For example, the display screens of the first display unit 2 and the second display unit 11 are matched so that the display screen of the first display unit 2 can be continuously moved from the edge of the first display unit 2 near the second display unit 11 to the second display unit 11 for display. For example, please refer to Figure 7 When the function items and the graphic sub-areas described below are continuously moved on the first interface, the part of the graphic that disappears from the first interface will be displayed on the second display unit 11. In this way, the continuity of the screen can be presented, further enhancing the interactivity and technological feel of the first display unit 2 and the second display unit 11, and improving the visual effect.

[0078] For example, please refer to Figures 1 to 8The display device includes a knob operation section 10, a second display section 11 located radially inner to the knob operation section 10, and a first display section 2 located radially outer to the knob operation section 10. The knob operation section 10 and the first display section 2 are arranged adjacent to each other. In this way, the second display section 11 can make full use of the space radially inner to the knob operation section 10 to display the currently selected function, which helps to improve the compactness of the display device's structural layout.

[0079] It should be noted that you should refer to [link / reference]. Figure 9 The knob operating part 10 has an appropriate extension length in the direction of its rotation axis for easy gripping by the user. That is, the knob operating part 10 is generally cylindrical. The annular circumferential outer surface is for the user to grip.

[0080] For example, both the second circuit board and the second display unit 11 are disposed radially inside the knob operation unit 10. This makes full use of the space radially inside the knob operation unit 10 and also facilitates the circuit arrangement between the second circuit board and the second display unit 11.

[0081] It is understandable that the second display unit 11 and the knob operation unit 10 can be components of the knob assembly 1.

[0082] For example, please refer to Figure 1 The first display unit 2 extends along a first direction, and the knob operation unit 10 is arranged adjacent to the first display unit 2 in the first direction. That is, the knob operation unit 10 is located at one end of the first display unit 2 in the first direction. Because the two are arranged adjacent to each other, it is beneficial to make the screens of the first display unit 2 and the second display unit 11 form a unified visual effect.

[0083] For example, please refer to Figures 1 to 4 , Figures 6 to 8 The second display section 11 is circular and arranged concentrically with the knob operation section 10. This allows the shapes of the second display section 11 and the knob operation section 10 to match better, resulting in a better visual effect and better space utilization.

[0084] For example, please refer to Figures 1 to 4 , Figures 6 to 8 An indicator light ring 12 is also provided between the knob operation section 10 and the second display section 11. The indicator light ring 12 is located radially inside the knob operation section 10 and surrounds the outer periphery of the second display section 11. Since the indicator light ring 12 is located between the first display section 2 and the knob operation section 10, please refer to... Figures 6 to 8 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.

[0085] The indicator light ring 12 refers to the area for displaying a circular bright light. That is, the user can see the indicator light ring 12.

[0086] Exemplarily, please refer to Figures 6 to 8 , the indicator light ring 12 and the knob operation part 10 are arranged at a radial interval of 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.

[0087] Exemplarily, please refer to Figures 6 to 8 , the indicator light ring 12 and the first display part 2 are arranged at a radial interval of 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.

[0088] Exemplarily, please refer to Figure 5 , when the knob assembly 1 is in the shutdown or standby state, the above non-display area and the first display part 2 show substantially the same color, for example, both are black. Thus, the appearance consistency in the shutdown or standby state can be improved.

[0089] Exemplarily, please refer to Figure 1 , the size D1 of the first display part 2 in the second direction is not less than the size D2 of the second display part 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 all 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 part 11 in the second direction is between the size of the second display part 11 in the second direction and the outer diameter of the knob operation part 10. Thus, the second display part 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.

[0090] Exemplarily, the second display part 11 is circular, and the second display part 11 is concentrically arranged with the knob operation part 10. Thus, the shapes of the second display part 11 and the knob operation part 10 can be better matched, the visual effect is good, and the space utilization rate is better.

[0091] Exemplarily, please refer to Figure 1 , the outer diameter D2 of the second display part 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 between the second display part 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 part 2 has a suitable area to display the picture.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] For example, in some embodiments, the knob operation unit 10 inputs a selection command by rotation. Specifically, the rotation angle of the knob operation ring 10 can be detected by a detection structure. The rotation angle of the knob operation ring 10 is associated with the function item on the first interface, and the selection command can be input based on the rotation angle of the knob operation ring 10. For example, every time the knob operation ring 10 rotates 30°, one function item on the first interface moves to the second display unit 11 for display. When the knob operation ring 10 rotates another 30°, another function item moves to the second display unit 11 for display. If the knob operation ring 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 ring 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 will directly display the second selected function item.

[0096] In other embodiments, the first display unit 2 includes a first touch-sensitive detection unit, which inputs a selection command by detecting a sliding or clicking operation performed on the first touch-sensitive detection unit. Specifically, for example, when a user slides or clicks on the surface of the first touch-sensitive detection unit, the function items on the first interface of the first display unit 2 can move, and the movement of the function items is related to the sliding distance or the number of clicks.

[0097] 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.

[0098] 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.

[0099] The working principles of the first and second touch-sensitive detection units are the same, and will not be elaborated here.

[0100] It should be noted that the function items can move continuously or in leaps 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, silk, wool, 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 moves from the first display unit 2 to the second display unit 11 for display. If the first touch-sensitive detection unit is clicked a second time, the silk function item moves from the first display unit 2 to the second display unit 11 for display. At this time, the second display unit 11 displays the silk function item and does not display the color protection wash function item. That is to say, when the next function item moves to the second display unit 11 for display, it will automatically overwrite the previous function item displayed on the second display unit 11, and so on.

[0101] 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.

[0102] For example, please refer to Figures 2 to 4 The first interface includes multiple graphic sub-areas 2a, each of which displays a functional item. For example, the graphic sub-area 2a is circular.

[0103] In some embodiments, multiple functional items are used to move synchronously in multiple graphic sub-regions 2a according to input selection instructions, and the position of the graphic sub-regions 2a remains unchanged.

[0104] In other embodiments, please refer to Figure 7 The graphic sub-area 2a and the functional items located within it move synchronously when a selection command is input.

[0105] For example, with Figure 2Taking the displayed state as an example, the first interface displays four graphic sub-areas 2a side by side. The color-protecting wash function is displayed in the first graphic sub-area 2a, the silk function is displayed in the second graphic sub-area 2a, the wool function is displayed in the third graphic sub-area 2a, and the anti-color-bleeding function is displayed in the fourth graphic sub-area 2a. During the first movement, the color-protecting wash function moves from the first graphic sub-area 2a to the second display section 11, the silk function moves from the second graphic sub-area 2a to the first graphic sub-area 2a, the wool function moves from the third graphic sub-area 2a to the second graphic sub-area 2a, and the anti-color-bleeding function moves 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 is directly switched to Figure 3 The status is shown below.

[0106] For example, with Figure 4 Taking the displayed state as an example, the first interface displays four graphic sub-areas 2a side by side. The silk function item is displayed in the first graphic sub-area 2a, the wool function item is displayed in the second graphic sub-area 2a, the anti-color bleeding function item is displayed in the third graphic sub-area 2a, and the quick wash function item is displayed in the fourth graphic sub-area 2a. During the first movement, each graphic sub-area 2a and its corresponding function item moves continuously. See [link to movement state] for one of the movement states. Figure 7 The silk feature item moves from the second graphic sub-area 2a to the first graphic sub-area 2a, that is, from... Figure 6 The display shows the status and experience. Figure 7 The intermediate display state shown in Figure 8 will be switched to the display state shown in Figure 8.

[0107] For example, each graphic sub-region 2a has the same shape and the same area.

[0108] Of course, in other embodiments, the area of ​​individual graphic sub-regions 2a may be larger than the area of ​​the other graphic sub-regions 2a.

[0109] For example, the area of ​​the second display unit 11 is larger than the area of ​​any graphic sub-area 2a. Thus, when a function item icon is moved to the second display unit 11, it has the effect of enlarging the screen and highlighting key points.

[0110] For example, multiple graphic sub-regions 2a are arranged at intervals along a first direction.

[0111] 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.

[0112] For example, please refer to Figures 1 to 8 The display device also includes a third display unit 3.

[0113] 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.

[0114] The switch operation area 3A detects the operations performed on 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.

[0115] The start / stop operation area 3B detects the operations performed on it to input start / stop commands for home appliances. The start / stop operation area 3B can also be referred to as the pause button.

[0116] In this way, the power button and pause button can be integrated into the display device, improving the integration level of the display device.

[0117] For example, an on / off switch indicator is also present in the switch operation area 3A. An on / off switch indicator is also present in the start / stop operation area 3B; please refer to [link / reference]. Figure 5 Even when the third display unit 3 is off (when the household appliance is in standby or off state), the power button and start / stop button indicators can still be identified. This allows users to quickly identify the locations of the power switch operation area 3A and the start / stop operation area 3B, facilitating 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.

[0118] For example, the third display unit 3, the knob operation unit 10 and the first display unit 2 are arranged adjacent to each other in the first direction, and the knob operation unit 10 is located between the first display unit 2 and the third display unit 3. It can also be understood that the second display unit 11 is located between the first display unit 2 and the third display unit 3.

[0119] Thus, the third display unit 3, the knob operation unit 10, 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.

[0120] 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).

[0121] 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.

[0122] 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.

[0123] 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.

[0124] For example, in the orthographic projection of the plane where the first display part 2 is located, that is, in the orthographic projection of the plane perpendicular to the axis of the knob operation part 10, the outer periphery of the knob operation part 10 has a first convex arc segment, and the boundary of the first display part 2 has a first concave arc segment, and the first convex arc segment and the first concave arc segment coincide.

[0125] Please see Figure 2 The outer periphery of the knob operation part 10, located between the positions of arrows B1 and B2, forms a first convex arc segment, and the boundary of the first display part 2, located between the positions of arrows B1 and B2, forms a first concave arc segment.

[0126] Thus, the outline of the outer periphery of the knob operation section 10 defines the display boundary of the first display section 2. Please refer to [link / reference]. Figure 6 Paper Figure 8 There is almost no gap between the knob operation section 10 and the first display section 2, which helps to further improve the visual connection between the first display section 2, the knob operation section 10, and the second display section 11.

[0127] For example, in the orthographic projection of the plane where the first display part 2 is located, that is, in the orthographic projection of the plane perpendicular to the axis of the knob operation part 10, the outer periphery of the knob operation part 10 has a second convex arc segment, and the boundary of the third display part 3 has a second concave arc segment, and the second convex arc segment and the second concave arc segment coincide.

[0128] Please see Figure 2The outer periphery of the knob operation section 10, located between the positions of arrows B3 and B4, forms a second convex arc segment, and the boundary of the third display section 3, located between the positions of arrows B3 and B4, forms a second concave arc segment.

[0129] Thus, the outline of the outer periphery of the knob operation section 10 defines the display boundary of the third display section 3, and there is almost no gap of non-display area between the knob operation section 10 and the third display section 3, which is conducive to further improving the visual connection effect between the third display section 3, the knob operation section 10, and the second display section 11.

[0130] For example, please refer to Figure 9 and Figure 11 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 one side of the mounting bracket 33. The panel assembly 31 is generally flat, and when the display device is installed on the home appliance, the panel assembly 31 serves as the exterior surface of the display device and also constitutes part of the exterior surface of the home appliance.

[0131] For example, please refer to Figure 9 and Figure 11 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.

[0132] 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-blocking. 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.

[0133] The knob operating part 10 is located on the side of the panel assembly 31 away from the mounting bracket 33. That is, the knob operating part 10 and the mounting bracket 33 are located on opposite sides of the panel assembly 31.

[0134] For example, in the orthographic projection of the plane where the first display unit 2 is located, the projection of the knob operation unit 10 overlaps with the first display screen 34, that is, a portion of the knob operation unit 10 is superimposed on the side of the first display screen 34 facing the exterior. Light outside the overlapping area of ​​the first display screen 34 passes through the panel assembly 31 to define the first display unit 2 in a portion of the panel assembly 31.

[0135] In this embodiment, the knob operation part 10 blocks a portion of the display area of ​​the first display screen 34. The display area of ​​the first display screen 34 covered by the knob operation part 10 is not exposed on the exterior surface of the display device. In other words, the user cannot see the area of ​​the first display screen 34 covered by the knob operation part 10. Thus, a portion of the peripheral contour of the knob operation part 10 can serve as the boundary of the first display part 2, resulting in better aesthetic coordination and / or matching between the knob operation part 10 and the first display part 2. Furthermore, the first display screen 34 can adopt a regular rectangular shape, eliminating the need for an irregular shape, which helps reduce the cost and manufacturing difficulty of the first display screen 34.

[0136] For example, please refer to Figure 11 The 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 panel assembly 31. 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.

[0137] It should be noted that the area of ​​the end cap 14 to be used for display is a light-transmitting part, while another part can be light-blocking. The end cap 14 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 end cap 14 for touch control. That is to say, the display area defined by a part of the end cap 14 and the second display screen 11" can be understood as the aforementioned second display part 11.

[0138] The type of the first display screen 34 is not limited; for example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0139] The type of the second display screen 11” is not limited; for example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0140] For example, the mounting bracket 33 has a through hole 33b, through which a portion of the structure of the knob assembly 1 passes.

[0141] For example, the display device includes an RGB light group, and the mounting bracket 33 has a light cavity 33a; the RGB light group is disposed in the light cavity 33a, and the panel assembly 31 covers at least the light cavity 33a; the light from the RGB light group passes through the panel assembly 31 to define a third display section 3 in a portion of the panel assembly 31.

[0142] The RGB light group works by controlling the current of the red, green, and blue LEDs to change the brightness, and then achieving color effects 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 displaying animations or other visuals. This helps reduce the cost of the third display unit 3.

[0143] 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.

[0144] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0145] 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.

[0146] For example, please refer to Figure 9 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 3131. The light-diffusing sheet 3535 is used to perform light-diffusing processing to make the light more uniform and softer.

[0147] For example, when projected onto a plane perpendicular to the axis of the knob operation portion 10, the projection of the knob operation portion 10 overlaps with the lamp cavity 33a. In this embodiment, the knob operation portion 10 blocks the light projected by the RGB lamp group onto the panel assembly 31. The light blocked by the knob operation portion 10 will not be exposed on the surface of the display device, meaning that the user cannot see the area blocked by the knob operation portion 10. Thus, a portion of the peripheral contour of the knob operation portion 10 can serve as the boundary of the third display portion 3, resulting in better aesthetic coordination and / or matching between the knob operation portion 10 and the third display portion 3.

[0148] This application provides a display control method for a household appliance, which can be applied to any of the household appliances described in the above embodiments.

[0149] In some embodiments, please refer to Figure 12 The display control methods include:

[0150] S1. Based on the selection command, multiple function items on the first interface of the first display unit on the control display device are moved synchronously, and one or more of the multiple function items are moved from the first display unit 2 to the second display unit 11 along the movement direction for display. The second display unit 11 is used to display the currently selected function item.

[0151] 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. Furthermore, the interaction between the first display unit 2 and the second display unit 11 is enhanced, which helps improve the user experience. In addition, inputting a selection command can cause multiple function items on the first interface to move synchronously, for example, along a straight path or a curved path, forming an overall sliding effect, resulting in better visual effects and human-computer interaction.

[0152] For example, the display control method further includes:

[0153] The second display unit 11 is configured to display the currently selected function item;

[0154] Based on the start command of the home appliance, the home appliance is controlled to execute the program corresponding to the function item displayed on the second display unit 11.

[0155] In this embodiment, when the second display unit 11 displays the currently selected function item and the first display unit 2 displays the first interface, the home appliance can directly start the program corresponding to the currently selected function item displayed on the second display unit 11, which is simple to operate.

[0156] For example, the start / stop operation area 3B mentioned above inputs a start command by detecting the operation performed on the start / stop operation area 3B.

[0157] For example, in some embodiments, the display control method includes: causing the first display unit 2 to display a first interface based on a power-on command of a household appliance. That is, after power-on, multiple function items appear on the power-on interface of the first display unit 2, so that the selectable function items can be displayed without any other operation.

[0158] It should be noted that the power-on interface in this application embodiment refers to the interface displayed on the display unit after the home appliance is turned on by inputting the power-on command, without the need for user intervention.

[0159] For example, the display control method further includes: causing the first display unit 2 to display a power-on interface based on a power-on command of a household appliance; and controlling the first display unit 2 to switch from the power-on interface to the first interface based on a first interface wake-up command.

[0160] In this embodiment, the selectable function items are not displayed on the boot screen of the first display unit 2, but are woken up by inputting a wake-up command. For example, the boot screen of the first display unit 2 can display an animation or a screensaver, and when a wake-up command is input, the first display unit 2 switches from the boot screen to the first screen.

[0161] For example, the aforementioned switch operation area 3A inputs a power-on command by detecting the operation performed on the switch operation area 3A.

[0162] For example, a wake-up command can be input by turning the knob operation unit 10, touching the first display unit 2, or touching the second display unit 11.

[0163] For example, the display control method includes: when controlling the second display unit 11 to display the selected function item, controlling the first display unit 2 to display the remaining function items other than the selected function item.

[0164] 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.

[0165] For example, the display control method further includes: when controlling the second display unit 11 to display a selected function item, controlling the background image of the first display unit 2 to match 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.

[0166] In this embodiment, the background image includes at least one of color, pattern coherence, and animation coherence.

[0167] 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.

[0168] 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.

[0169] For example, please see Figures 6 to 8 The background colors of the first display unit 2 and the second display unit 11 are both black, and the background colors of the first display unit 2 and the second display unit 11 play the animation in harmony.

[0170] For example, prior to the selection command, the display control method further includes controlling the second display unit 11 to display a power-on interface based on the power-on command of the household appliance, wherein the power-on interface includes a default function item. That is, a default function item is displayed on the power-on interface of the second display unit 11. Thus, if the user needs to use the default function item, they can directly input the start command, making the operation simpler and more convenient.

[0171] The default function items on the second display unit 11 remain unchanged. For example, in some embodiments, they can be system-defined default function items. Thus, the default function items on the startup screen of the second display unit 11 are always the same and will not change each time the device is powered on. In other embodiments, the function item previously used by the household appliance can be used as the default function item for the next use. In still other embodiments, the function item most frequently used by the user is used as the default function item.

[0172] Please see Figure 13 The following describes a display control method for a household appliance according to a specific embodiment.

[0173] 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.

[0174] Step S31, based on the power-on command. For example, the user presses, selects, or touches the switch operation area 3A to input the power-on command.

[0175] Step S32: After powering on, the first display unit 2 and the second display unit 11 respectively display their respective power-on interfaces, wherein the power-on interface of the second display unit 11 includes a default function item.

[0176] The third display unit 3 lights up and displays the corresponding color. The boot screen can be an animated display or a static image.

[0177] Step S33: Based on the first interface wake-up command, the first display unit is switched from the power-on interface to the first interface, wherein the first interface includes multiple selectable function items.

[0178] In step S34, based on the selection command, multiple function items on the first interface are moved synchronously, and one or more of the multiple function items are moved from the first display unit to the second display unit along the movement direction. The second display unit is used to display the currently selected function item. For example, this can be done by rotating the knob operation unit 10, or by sliding or clicking on the first display unit 2, or by sliding or clicking on the second display unit 11, until the desired function item is displayed on the second display unit 11. At this time, the remaining function items are still displayed on the first interface of the first display unit 2.

[0179] Step S35: Based on the start command, the home appliance executes the program corresponding to the function item currently displayed on the second display unit.
