[0051] This application provides a display device. The display device can be used in household appliances.

[0052] 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.

[0053] There are no restrictions on the type of household appliances; for example, they can be cooking appliances, clothing processing equipment, etc.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] The garment treatment equipment can also be equipped with a steam unit for deodorizing, wrinkle removal and other care of garments.

[0058] The control motherboard is used to control the operation of the entire machine.

[0059] Please see Figures 1 to 3 The display device includes a first display unit 2 and a knob assembly 1. The knob assembly 1 and the first display unit 2 are in a first direction (refer to...). Figure 5 Adjacent arrangement on the top.

[0060] 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.

[0061] The knob assembly 1 includes a knob operation section 10 and a second display section 11 disposed radially inside the knob operation section 10. It should be noted that 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 the interface, which helps to improve the compactness of the display device's structural layout.

[0062] Since the knob assembly 1 and the first display unit 2 are arranged adjacent to each other in the first direction, it is advantageous to make the screens of the first display unit 2 and the second display unit 11 display as a whole.

[0063] It should be noted that you should refer to [link / reference]. Figures 9 to 12 The knob operating portion 10 has an appropriate extension length in the direction of its rotation axis for easy gripping by the user. Exemplarily, the knob operating portion 10 is generally cylindrical, with an annular circumferential outer surface for the user to grip.

[0064] For example, the first display unit 2 can be used to play dynamic images, that is, the first display unit 2 uses a display screen for display.

[0065] For example, the second display unit 11 can be used to play dynamic images, that is, the second display unit 11 uses a display screen for display.

[0066] For example, please refer to Figures 1 to 3 The background of the display interface of the first display unit 2 is coordinated with the background of the display interface of the second display unit 11.

[0067] It should be noted that background coordination can include background color coordination and / or graphic coordination and / or background animation coordination.

[0068] The background can be, for example, the color of the image or animation of the most eye-catching, largest, or most meaningful part of the display interface. For instance, the background color (or animation) of the entire display interface of the second display 11 can be used as a reference part, and the background color (or animation) of the display interface of the first display 2 can be coordinated with the reference part.

[0069] In this way, the overall visual effect of the first display unit 2 and the second display unit 11 can be further enhanced, so as to form a visually harmonious, unified or visually strong contrast display effect, resulting in a better visual effect.

[0070] For example, please see Figure 1 The background color of the second display unit 11 is red, and the color of the first display unit 2 near the second display unit 11 is also almost the same red, except that the first display unit 2 uses a gradient color overall. Please refer to... Figure 2 The background color of the second display unit 11 is purple, and the color of the first display unit 2 near the end of the second display unit 11 is also purple, except that the first display unit 2 uses a gradient color throughout. Please refer to [link / reference]. Figure 3 The background color of the second display unit 11 is blue, and the color of the end of the first display unit 2 near the second display unit 11 is also blue.

[0071] In the above embodiments, the background of the display interface of the first display unit 2 and the background of the display interface of the second display unit 11 are coordinated and unified, which is conducive to further improving the overall visual effect of the display device.

[0072] For example, both the first display unit 2 and the second display unit 11 are used to display dynamic images, for example, both of which use a display screen. The images of the first display unit 2 and the second display unit 11 are coordinated so that the first display unit 2 and the first display unit 11 jointly display visually coherent images or animations, which can also be understood as a continuous screen effect.

[0073] The image coordination includes, but is not limited to, one or more of the following situations: the image displayed on the first display unit 2 and the image displayed on the first display unit 11 constitute a complete image; the graphics or animation move dynamically and coherently on the first display unit 2 and the second display unit 11, and the visuals are coherent animations.

[0074] For example, background coordination includes graphic coordination. The graphic on the first display unit 2 and the graphic on the second display unit 11 can move continuously between the first display unit 2 and the second display unit 11; or, the first display unit 2 and the second display unit 11 can collaboratively display different parts of the same dynamic image. For example, the graphic on the first display unit 2 can move continuously from the edge of the first display unit 2 near the second display unit 11 to the second display unit 11 for display; and / or, the graphic on the second display unit 11 can move continuously from the edge of the second display unit 11 near the first display unit 2 to the first display unit 2 for display. Alternatively, the same image can be partially displayed on the first display unit 2 and partially displayed on the second display unit 11, with the first display unit 2 and the second display unit 11 constituting a complete image.

[0075] Please see Figure 2 When the displayed graphics move between the first display unit 2 and the second display unit 11, the edges of the graphics on the first display unit 2 and the second display unit 11 that are close to each other are also coordinated. In this way, the display coordination and interactivity of the first display unit 2 and the second display unit 11 can be improved, giving the display device a better sense of technology and helping to improve the user experience.

[0076] For example, the first display section 2 extends along a first direction, that is, the first display section 2 is generally elongated, and the knob operation section 10 is disposed at one end of the first display section 2 in the first direction.

[0077] For example, in the orthographic projection of a plane perpendicular to the axis of the knob operation section 10, the outer periphery of the knob operation section 10 has a first convex arc segment, and the boundary of the first display section 2 has a first concave arc segment, with the first convex arc segment and the first concave arc segment coinciding.

[0078] Please see Figure 6 and Figure 8 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.

[0079] 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]. Figures 1 to 3 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.

[0080] It should be noted that a portion of the knob operation part 10 is located on the outside of the first display part 2, so that the knob operation part 10 blocks a portion of the display screen corresponding to the first display part 2, thereby forming the aforementioned first convex arc segment and first concave arc segment on the projection surface.

[0081] For example, please refer to Figures 1 to 8 The display device also includes a third display unit 3.

[0082] For example, the third display unit 3, the knob assembly 1, and the first display unit 2 are arranged adjacent to each other in the first direction, with the knob assembly 1 located between the first display unit 2 and the third display unit 3. Alternatively, it can be understood that, in orthographic projection onto a plane perpendicular to the axis of the knob operation unit 10, the second display unit 11 is located between the first display unit 2 and the third display unit 3. Thus, the third display unit 3, the knob operation unit 10, and the first display unit 2 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.

[0083] 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).

[0084] For example, in orthographic projection onto a plane perpendicular to the axis of the knob operation portion 10, the outer periphery of the knob operation portion 10 has a second convex arc segment, and the boundary of the third display portion 3 has a second concave arc segment, with the second convex arc segment and the second concave arc segment coinciding. Please refer to [link / reference]. Figure 6 and Figure 8 The 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.

[0085] It should be noted that a portion of the knob operation part 10 is located outside the third display part 3, so that the knob operation part 10 blocks a portion of the display structure corresponding to the third display part 3, thereby forming the aforementioned second convex arc segment and second concave arc segment on the projection surface.

[0086] 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.

[0087] For example, please refer to Figures 5 to 8 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.

[0088] 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.

[0089] 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.

[0090] In this way, the power button and pause button can be integrated into the display device, improving the integration level of the display device.

[0091] 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 4 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.

[0092] For example, the outline of the area jointly formed by the first display unit 2 and the third display unit 3 is roughly rectangular. However, it should be noted that the long side of the rectangle is discontinuous and is broken at the knob assembly 1.

[0093] For example, please refer to Figures 1 to 3 , Figures 5 to 8 The knob assembly 1 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. Since the indicator light ring 12 is located between the first display portion 2 and the knob operating portion 10, please refer to... Figures 1 to 3 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.

[0094] Indicator ring 12 refers to the area used to display a ring of light. In other words, the user can see indicator ring 12.

[0095] For example, the color of the indicator light ring 12 is coordinated with or substantially consistent with the colors of the first display unit 2 and the second display unit 11. It should be noted that the colors of the indicator light ring 12, the first display unit 2, and the second display unit 11 may only be coordinated with or substantially consistent during certain periods, or they may be coordinated with or substantially consistent throughout the entire process.

[0096] That is to say, the color of the indicator light ring 12 can change. For example, the color of the indicator light ring 12 changes following the screen of the second display unit 11.

[0097] In this embodiment, the indicator light ring 12 can further enhance the overall display coordination of the display device, and the display effect is better.

[0098] Exemplarily, 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.

[0099] Exemplarily, the indicator light ring 12 and the first display unit 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 unit 2 is a non-display area.

[0100] Exemplarily, please refer to Figure 4 , when the knob assembly 1 is in the shutdown or standby state, the colors presented by the above non-display area and the first display unit 2 are substantially the same. For example, they are both black. In this way, the appearance consistency in the shutdown or standby state can be improved.

[0101] Exemplarily, please refer to Figure 5 , the size D1 of the first display unit 2 in the second direction is not less than the size 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. In this way, 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.

[0102] Exemplarily, the second display unit 11 is circular, and the second display unit 11 is concentrically arranged with the knob operation part 10. In this way, 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.

[0103] Exemplarily, please refer to Figure 5The outer diameter D of the second display section 11 is 1 / 3 to 2 / 3 of the outer diameter D3 of the knob operation section 10. That is, D3*1 / 3≤D2≤D3*2 / 3. The size ratio of the second display section 11 and the knob operation section 10 is relatively moderate and reasonable. While the size of the knob operation section 10 is convenient for the user to hold, the first display section 2 has a suitable area to display the screen.

[0104] 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.

[0105] 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.

[0106] For example, please refer to Figure 5 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.

[0107] For example, please refer to Figure 5 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.

[0108] 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.

[0109] Functional items can be displayed in text and / or graphic form; there are no restrictions on this. For example, please refer to... Figures 1 to 3 , Figures 6 to 8 In some specific implementations, functional items are displayed in text form.

[0110] The specific content of the functional items on the first interface can be set according to the functions of home appliances.

[0111] 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.

[0112] 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.

[0113] The display device includes a control unit for operating 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 screen of the first display unit 2 and the second circuit board is used to operate the screen of the second display unit 11.

[0114] 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.

[0115] 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.

[0116] The control unit is used to control the second display unit 11 to display the selected function item based on the selection command, wherein the selection command includes selecting one of a plurality of function items on the first interface.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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, which is convenient to prompt the user in a prominent way; 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.

[0121] For example, please refer to Figures 1 to 3 , Figures 6 to 8 The control unit is also used to control the first display unit 2 to display the remaining function items besides the selected function item when the second display unit 11 displays 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.

[0122] For example, the control unit is also used to control multiple function items on the first interface to move synchronously based on the selection command, and to move one or more of the multiple function items from the first display unit 2 to the second display unit 11 for display along the movement direction, and the second display unit 11 is used to display the currently selected function item.

[0123] It should be noted that when one or more of the multiple function items move from the first display unit 2 to the second display unit 11 along the moving direction, it means that if a single input selection command moves only 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, then the multiple function items leave the first display unit 2 sequentially and are displayed sequentially 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 6 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 7 If 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 6 The display status shown has switched to Figure 7 The display status is shown below.

[0124] In this embodiment, inputting a selection command can cause multiple functional items on the first interface to move synchronously. For example, they can move along a straight path or along a curved path, forming an overall sliding effect, which improves the visual effect and human-computer interaction.

[0125] For example, multiple function items move synchronously along a first direction when a selection command is input. For instance, 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 can be either moving towards the second display unit 11 or moving away from the second display unit 11.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] For example, in some embodiments, the knob operation unit 10 inputs a selection command by rotating it. Specifically, the rotation angle of the knob operation unit 10 can be detected by a detection structure, and the rotation angle of the knob operation unit 10 is associated with a function item on the first interface, so that a selection command can be input based on the rotation angle of the knob operation unit 10.

[0131] For example, every time the knob operation unit 10 is rotated 30°, one of the function items on the first interface moves to the second display unit 11 for display. When the knob operation unit 10 is rotated another 30°, the other function item moves to the second display unit 11 for display. If the knob operation unit 10 is rotated continuously by 60°, the second display unit 11 displays the two function items sequentially, presenting a scrolling display effect. It can be understood that if the knob operation unit 10 is rotated continuously by 60° 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] The working principles of the first and second touch-sensitive detection units are the same, and will not be elaborated here.

[0136] 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.

[0137] 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.

[0138] For example, please refer to Figures 1 to 3 , Figures 6 to 8 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.

[0139] In some embodiments, multiple functional items are used to move synchronously in multiple graphic sub-regions 2a when a selection command is input, and the position of the graphic sub-regions 2a remains unchanged.

[0140] In other embodiments, please refer to the figure, the graphic sub-area 2a and the functional items located within the graphic sub-area 2a move synchronously when a selection command is input.

[0141] For example, with Figure 6 Taking 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 quick wash function is displayed in the fourth graphic sub-area 2a, i.e., from... Figure 6 The displayed status is directly switched to Figure 7 The status is shown below.

[0142] For example, with Figure 1 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 2 The silk feature item moves from the second graphic sub-area 2a to the first graphic sub-area 2a, that is, from... Figure 1 The display shows the status and experience. Figure 2 The intermediate display state shown has been switched to... Figure 3 The status is shown below.

[0143] For example, each graphic sub-region 2a has the same shape and the same area.

[0144] 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.

[0145] 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.

[0146] For example, multiple graphic sub-regions 2a are arranged at intervals along a first direction.

[0147] For example, please refer to Figure 9 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 knob operating part 10 is located on the side of the panel assembly 31 away from the mounting bracket 33.

[0148] The panel assembly 31 is flat in shape. 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 forms part of the exterior surface of the home appliance.

[0149] 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.

[0150] 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.

[0151] The light from the first display screen 34 passes through the panel assembly 31 to define the first display section 2 in a portion of the panel assembly 31.

[0152] For example, in orthographic projection onto a plane perpendicular to the axis of the knob operation portion 10, the projection of the knob assembly 1 overlaps with the first display screen 34, that is, a portion of the knob operation portion 10 is superimposed on the side of the first display screen 34 facing the exterior. Light from the first display screen 34 outside the overlapping area passes through the panel assembly 31 to define the first display portion 2 in a portion of the panel assembly 31.

[0153] 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 blocked by the knob operation part 10 is not exposed on the exterior surface of the display device. That is, the user cannot see the area of ​​the first display screen 34 blocked 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, making the appearance of the knob operation part 10 and the first display part 2 more coordinated and / or matched. In addition, the first display screen 34 can adopt a regular rectangular shape, without the need for an irregular shape, which helps to reduce the cost and manufacturing difficulty of the first display screen 34. In this embodiment, since the knob operation part 10 blocks a portion of the display area of ​​the first display screen 34, the aforementioned first convex arc segment and first concave arc segment can be formed.

[0154] For example, please refer to Figure 11 and Figure 12 The knob assembly 1 includes a mounting component 13, a second display screen 11", and an end cap 14. The mounting component 13 is connected to the panel assembly 31. The knob operating part 10 surrounds the outer periphery of the mounting component 13 and is rotatable relative to the mounting component 13. The knob assembly 1 is connected to the panel assembly 31 through the mounting component 13. That is, the panel assembly 31 provides mounting support and positioning for the knob assembly 1.

[0155] It should be noted that you should refer to [link / reference]. Figure 9 The panel assembly 31 has a clearance hole 31a through which a portion of the mounting assembly 13 passes.

[0156] End cap 14 is located radially inside knob operating part 10, and end cap 14 is disposed on the axial side of mounting assembly 13 on knob operating part 10. Second display screen 11" is disposed between end cap 14 and mounting assembly 13. End cap 14 serves as the outer surface of knob assembly 1.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] For example, the mounting bracket 33 has a through hole 33b, through which a portion of the structure of the knob assembly 1 passes.

[0161] For example, the display device includes an RGB light group 321 and a mounting bracket 33 having a light cavity 33a; the RGB light group 321 is disposed in the light cavity 33a, and the panel assembly 31 at least covers the light cavity 33a; the light from the RGB light group 321 passes through the panel assembly 31 to define a third display section 3 in a portion of the panel assembly 31.

[0162] For example, the RGB light group 321 is disposed on the RGB circuit board 322.

[0163] The RGB light group 321 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.

[0164] 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.

[0165] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0166] 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.

[0167] 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 31. The light-diffusing sheet 35 is used to perform light-diffusing processing to make the light more uniform and softer.

[0168] For example, the colors of the third display unit 3, the background color of the first display unit 2, and the background color of the second display unit 11 are coordinated or substantially the same. See, for example, [link to relevant documentation]. Figure 1 The background color of the second display unit 11 is red, and the RGB light group 321 also displays a red color on the panel assembly 31. Meanwhile, the background color of the first display unit 2 is also approximately red. For another example, please refer to... Figure 2All three are roughly purple in color. Please refer to [link / reference]. Figure 3 All three elements are dark blue. In the above embodiment, the three elements present a relatively harmonious and unified color tone, which is conducive to further enhancing the overall visual effect of the display device.

[0169] 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 lamp assembly onto the panel assembly 31. The light blocked by the knob operation portion 10 is not exposed on the surface of the display device; that is, 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. Specifically, since the knob operation portion 10 blocks the light projected by the lamp assembly onto the panel assembly 31, the aforementioned second convex arc and second concave arc can be formed.

[0170] For example, please refer to Figure 9 and Figure 12 The panel assembly 31 has a hollow cylindrical structure 311 formed on the side facing the mounting bracket 33. Please refer to [link / reference]. Figure 13 and Figure 14 The mounting bracket 33 has a through hole 33b, and a cylindrical structure 311 is disposed in the through hole 33b. A portion of the mounting assembly 13 is housed within and connected to the cylindrical structure 311. The cylindrical structure 311 improves the connection reliability between the panel assembly 31 and the mounting assembly 13. Using the through hole 33b to house the cylindrical structure 311 also facilitates the positioning of the panel assembly 31, reducing the probability of relative movement between the panel assembly 31 and the mounting bracket 33.

[0171] 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.

[0172] In some embodiments, please refer to Figure 12 The display control method includes the following steps S1 and S2.

[0173] S1. Responding to the power-on command of a household appliance. For example, the aforementioned switch operation area 3A inputs a power-on command by detecting the operation performed on the switch operation area 3A.

[0174] S2, to coordinate the display of the background of the display interface of the first display section 2 located radially outside the knob operation section 10 and the background of the display interface of the second display section 11 located radially inside the knob operation section 10.

[0175] The display interface can be the boot screen or other display interfaces that follow the boot screen, such as the first interface mentioned above.

[0176] In this way, the overall picture quality of the first display unit 2 and the second display unit 11 can be further enhanced, resulting in a better visual effect.

[0177] In some embodiments, the display control method further includes: causing the first display unit 2 to display a first interface, the first interface including a plurality of selectable function items; and, in response to a selection instruction to select one of the plurality of function items on the first interface, causing the second display unit 11 to display the currently 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. 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.

[0178] For example, the display control method further includes: when the second display unit 11 displays a currently selected function item, in response to the start command of the home appliance, causing the home appliance to execute the program corresponding to the function item displayed on the second display unit 11.

[0179] 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.

[0180] 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.

[0181] For example, in some embodiments, the step of displaying the first interface on the first display unit 2 as described above includes: in response to a power-on command from a household appliance, displaying a power-on interface on the first display unit 2, the power-on interface including the first interface. That is, after power-on, multiple function items appear on the power-on interface of the first display unit 2, thus displaying the selectable function items without requiring further operation.

[0182] 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.

[0183] For example, before the first display unit 2 displays the first interface, the display control method further includes: in response to a power-on command from a household appliance, causing the first display unit 2 to display a power-on interface. The step of causing the first display unit 2 to display the first interface includes: in response to a first interface wake-up command, switching the first display unit 2 from the power-on interface to the first interface.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] For example, prior to the steps before responding to the selection command, the display control method further includes: in response to a power-on command from the household appliance, causing the second display unit 11 to display a power-on interface, which 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 currently needs to use the default function item, they can directly input the start command, making operation simpler and more convenient.

[0189] 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.

[0190] Please see Figure 13 The following describes a display control method for a household appliance according to a specific embodiment.

[0191] It should be noted that in standby mode, please refer to [link / reference]. Figure 4 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.

[0192] Step S31, in response to a power-on command. For example, the user switches operation area 3A and inputs a power-on command.

[0193] 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.

[0194] The third display unit 3 lights up and displays the corresponding color. The boot screen can be an animated display or a static image.

[0195] Step S33: In response to the first interface wake-up command, the first display unit 2 is switched from the power-on interface to the first interface, wherein the first interface includes multiple selectable function items.

[0196] In step S34, in response to the selection command, multiple function items on the first interface are moved synchronously, and one or more of the multiple function items are moved along the movement direction from the first display unit 2 to the second display unit 11 for display. The second display unit 11 is used to display the currently selected function item. For example, the desired function item can be displayed on the second display unit 11 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. At this time, the remaining function items are still displayed on the first interface of the first display unit 2.

[0197] In step S35, in response to the start command, the home appliance executes the program corresponding to the function item currently displayed on the second display unit 11.

[0198] It should be noted that in any of the above method steps, the background of the display interface of the first display unit 2 and the background of the display interface of the second display unit 11 can be displayed in a coordinated manner.

[0199] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.
