[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 Figure 1 The display device includes a panel assembly 31, a mounting bracket 33, a first display screen 34, and a knob assembly 1.

[0060] The knob assembly 1 and the first display screen 34 are arranged adjacent to each other in a first direction.

[0061] 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.

[0062] The panel assembly 31 has a first side and a second side opposite to the first side in its thickness direction, wherein the surface of the second side faces the appearance surface of the display device, and the first side is the side opposite to the appearance surface.

[0063] The panel assembly 31 is generally plate-shaped, and when the display device is installed on the home appliance, the surface of the second side of the panel assembly 31 constitutes part of the appearance surface of the home appliance.

[0064] The mounting bracket 33 is disposed on one side of the panel assembly 31. Specifically, the mounting bracket 33 is disposed on the first side of the panel assembly 31 in the thickness direction.

[0065] The first display screen 34 is disposed between the mounting bracket 33 and the panel assembly 31. The mounting bracket 33 provides mounting support for other components of the display device.

[0066] It should be noted that the area of ​​the panel assembly 31 used for display is the light-transmitting part, while the remaining parts 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 part of the panel assembly 31 corresponding to the first display screen 34 to realize touch control.

[0067] The knob assembly 1 includes a knob operating part 10 and a second display screen 11” disposed radially inside the knob operating part 10. The knob operating part 10 is located on the side of the panel assembly 31 away from the mounting bracket 33 and can rotate relative to the panel assembly 31. That is, the knob operating part 10 is disposed on the second side of the panel assembly 31, that is, the side facing the exterior surface. The knob operating part 10 and the mounting bracket 33 are located on opposite sides of the panel assembly 31, and the knob operating part 10 and the first display screen 34 are located on opposite sides of the panel assembly 31.

[0068] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 4 The knob operating portion 10 has an appropriate extension length in the direction of its rotation axis for easy gripping by the user. For example, the knob operating portion 10 is generally cylindrical, with an annular circumferential outer surface for the user to grip.

[0069] Since the first display screen 34 is located radially inside the knob operation section 10, the second display screen 11" can make full use of the space radially inside the knob operation section 10 to display images, which is beneficial to improving the compactness of the display device's structural layout.

[0070] Please see Figure 2 In a plane perpendicular to the axis of the knob operation section 10, the knob assembly 1 and the first display screen 34 have an overlapping area. Figure 2 The shaded area indicated by the diagonal line represents the overlapping area of ​​the knob assembly 1 and the first display screen 34. It should be noted that when the display device is in the off state, the first display screen 34 is almost invisible from the outer surface of the panel assembly 31. Figure 2 The dashed outline in the diagram is only an example to illustrate the projection relationship between the first display screen 34 and the knob assembly 1.

[0071] In other words, in conjunction with reference Figure 4 A portion of the knob operating section 10 overlaps with 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 section 2 (see reference 10) in a portion of the panel assembly 31. Figures 7 to 9 That is, the display area presented on the outer surface of the display device by the second display screen 11" constitutes the second display section 11.

[0072] The aforementioned overlapping area can also be understood as follows: In a planar projection 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. The first convex arc segment and the first concave arc segment coincide, and the area of ​​the first display screen 34 located on the concave side of the first concave arc segment belongs to the aforementioned overlapping area. Please refer to [link / reference]. Figure 8The outer periphery of the knob operation part 10, located between the positions of arrow B1 and arrow B2, is a first convex arc segment, and the boundary of the first display part 2, located between the positions of arrow B1 and arrow B2, is a first concave arc segment.

[0073] 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. Please refer to [link to relevant documentation]. Figures 11 to 14 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, and makes the appearance of the knob operation section 10 and the first display section 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.

[0074] For example, please refer to Figure 1 , Figures 4 to 6 The mounting bracket 33 has a through hole 33b, and a portion of the knob assembly is accommodated in the through hole 33b. The through hole 33b facilitates the avoidance of a portion of the structure of the knob assembly 1 and also facilitates the passage of wiring for connection with the knob assembly 1. The wiring can be used for transmitting electrical energy, communication, etc.

[0075] Please see Figure 2 The axis of knob assembly 1 ( Figure 2 Point O in the diagram represents the distance L2 from the axis of the knob assembly 1 to the wall of the through hole 33b on the side closer to the first display screen 34. This distance L2 is less than the distance L1 from the axis of the knob assembly 1 to the wall of the through hole 33b on the side farther from the first display screen 34. <L1。

[0076] It should be noted that the distances L1 and L2 mentioned above are both distances on a straight line parallel to the first direction and passing through the axis of the knob assembly 1 (for example, this straight line is parallel to the axis of the knob assembly 1). Figure 2 The cutting lines of AA in the diagram are in the same position.

[0077] In this embodiment, the holes 33b have asymmetrical walls at opposite ends in the first direction, and the size of the hole closer to the first display screen 34 is smaller. Compared with circular or rectangular through holes, when the sizes of the knob assembly 1 and the first display screen 34 remain unchanged, the through hole 33b of this embodiment is advantageous in bringing the knob assembly 1 and the first display screen 34 closer together in the first direction, occupying less mounting bracket 33 in the first direction, which is beneficial for the compact structure of the display device.

[0078] 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.

[0079] 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.

[0080] In some embodiments, the second display screen 11" overlaps with the first display screen 34 in an orthographic projection onto a plane perpendicular to the axis of the knob operation section 10 (which can also be understood as a projection onto the plane where the display interface of the first display screen 34 is located). In this embodiment, since the first display screen 34 and the second display screen 11" overlap in this projection plane, their display interfaces are close to each other, which is more conducive to the visual continuity of the display screen of the first display screen 34 and the display screen of the second display screen 11" and the effect of multi-screen display is better.

[0081] For example, please refer to Figures 7 to 10 , Figures 12 to 14 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 12 to 14 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.

[0082] Indicator ring 12 refers to the area used to display a ring of light. In other words, the user can see indicator ring 12.

[0083] For example, please refer to Figures 12 to 14 The indicator light ring 12 and the knob operation part 10 are arranged radially at a distance from each other on the knob operation part 10, and the interval area between the indicator light ring 12 and the knob operation part 10 is a non-display area.

[0084] For example, please refer to Figures 12 to 14 The indicator light ring 12 and the first display part 2 are arranged radially at a distance from each other in the knob operation part 10, and the interval area between the indicator light ring 12 and the first display part 2 is a non-display area.

[0085] For example, please refer to Figure 11When the knob assembly 1 is in the power-off or standby state (which can be understood as the screen-off state), the non-display area and the first display unit 2 are displayed in roughly the same color, for example, both are black. This improves the consistency of appearance when the device is powered off or in standby state.

[0086] 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.

[0087] In other words, the color of the indicator ring 12 can change; for example, the color of the indicator ring 12 can change according to the screen of the second display unit 11.

[0088] In this embodiment, the indicator light ring 12 can further enhance the overall display coordination of the display device and improve the display effect.

[0089] It should be noted that, in the embodiments of this application, unless otherwise specified or otherwise, the terms "same color," "matching color," and "coordinated color" refer to the colors presented when the device is powered on and displayed.

[0090] For example, please refer to Figure 1 The first display screen 34 extends along a first direction, that is, the first display unit 2 extends along a first direction; the knob operation unit 10 is arranged adjacent to the first display screen 34 in the first direction. That is, the knob operation unit 10 is located at one end of the first display screen 34 in the first direction. Since 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.

[0091] For example, the first display screen 34 is rectangular. The long side of the rectangle is approximately parallel to a first direction, and the short side of the rectangle is parallel to a second direction. It is understood that since the knob assembly 1 and the first display screen 34 have an overlapping area, the junction between the first display part 2 and the knob assembly 1 has an arc-shaped boundary. However, while forming an arc-shaped boundary, the shape of the first display screen 34 can be a regular rectangle, which facilitates manufacturing and reduces costs.

[0092] For example, please refer to Figure 2, the outer diameter of the knob operation part 10 is greater than the length of the first display screen 34 in the second direction, and the knob assembly 1 at least blocks the short side of the rectangle near the end of the rectangle close to the knob assembly 1. It can be understood that the knob assembly 1 can just completely block the short side of the rectangle without blocking a part of the long side of the rectangle; the knob assembly 1 can also completely block the short side of the rectangle and also block a part of the long side of the rectangle. In this embodiment, the knob assembly 1 completely blocks the short side of the rectangle, which is beneficial to further improving the appearance visual effect.

[0093] Exemplarily, the second display screen 11" is circular, and the second display part 2 is also circular; and they are concentrically arranged with the knob operation part 10. In this way, it can make the shapes of the second display screen 11" and the knob operation part 10 more matched, with better visual effect and better space utilization.

[0094] Exemplarily, the size of the panel assembly 31 in the second direction is greater than the outer diameter of the knob operation part 10.

[0095] Exemplarily, please refer to Figure 7 , 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. In this way, 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.

[0096] Exemplarily, please refer to Figure 7 , 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 22 has a suitable area to display the picture.

[0097] In some specific embodiments, D3*1 / 2≤D2≤D3*2 / 3, and the second display part 11 has a larger area to display the picture.

[0098] Exemplarily, please refer to Figure 7The 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.

[0099] For example, please refer to Figure 5 and Figure 6 The mounting bracket 33 has grooves 33c arranged adjacent to each other in a first direction, and at least a portion of the first display screen 34 in the thickness direction is accommodated in the grooves 33c. Thus, the grooves 33c facilitate the positioning of the first display screen 34 and reduce the probability of the first display screen 34 shifting.

[0100] For example, please refer to Figure 5 and Figure 6 The wall of the through hole 33b includes an arc-shaped wall, and the circular trajectory of the arc-shaped wall overlaps with the groove 33c. That is to say, the shape of the through hole 33b is not a complete circular hole. This helps to shorten the distance between the center of the first display screen 34 and the center of the arc-shaped wall, and facilitates the stacking of the first display screen 34 and the knob assembly 1 in the thickness direction.

[0101] For example, please refer to Figure 5 and Figure 6 The mounting bracket 33 includes a spacer wall 331, a groove 33c and a through hole 33b located on opposite sides of the spacer wall 331 in a first direction, and both ends of the arc-shaped wall are connected to the spacer wall 331, with the spacer wall 331 serving as part of the groove wall of the groove 33c. This makes the structure of the mounting bracket 33 compact.

[0102] For example, please refer to Figures 4 to 6 The mounting bracket 33 has a lamp cavity 33a. The display device includes a light source assembly 32, which is disposed in the lamp cavity 33a. The light from the light source assembly 32 passes through the panel assembly 31 to form a display area on the panel assembly 31. This display area can be referred to as the third display section 3.

[0103] In other words, the third display unit 3 can display corresponding colors, enriching the display effect of the display device.

[0104] For example, when projected onto a plane perpendicular to the axis of the knob operation section 10, the knob assembly 1 and the lamp cavity 33a have an overlapping area.

[0105] Thus, in the orthographic projection onto a plane perpendicular to the axis of the knob operation section 10, the outer periphery of the knob operation section 10 has a second convex arc segment, and the boundary of the third display section 3 has a second concave arc segment, with the second convex arc segment and the second concave arc segment coinciding.

[0106] Specifically, please refer to Figure 8The outer periphery of the knob operating part 10, located between the positions of arrow B3 and arrow B4, forms a second convex arc segment, and the boundary of the third display part 3, located between the positions of arrow B3 and arrow B4, forms a second concave arc segment. The area of ​​the third display part 3 located on the concave side of the second concave arc segment is an overlapping area.

[0107] 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.

[0108] In this embodiment, the knob operation portion 10 blocks the light projected from the light source assembly 32 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 of ​​the lamp cavity 33a 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.

[0109] For example, please refer to Figure 1 and Figure 4 The light source assembly 32 includes an RGB circuit board 322 and an RGB light group 321, with the RGB light group 321 positioned on the side of the RGB circuit board 322 facing the panel assembly 31. The RGB light group 321 works by controlling the current of the red, green, and blue LEDs to change the brightness, thereby 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 and does not need to present animations or other visuals. This helps reduce the cost of the third display unit 3.

[0110] For example, the panel assembly 31 has a switch operation area 3A covering the lamp cavity 33a. The switch operation area 3A receives a power-on / power-off command by detecting input operations applied to it; for example, this power-on / power-off command is a power-on / power-off command for a household appliance. The switch operation area 3A can also be understood as the on / off switch of a household appliance, which can also be called a power button. And / or, the panel assembly 31 has a start / stop operation area 3B covering the lamp cavity 33a. The start / stop operation area 3B receives a start / stop command by detecting input operations applied to it; for example, this start / stop command is a start / stop command for a household appliance. The start / stop operation area 3B can also be called a pause button. It should be noted that the input operation can include pressing or touching operations, but specific limitations are not provided here.

[0111] In this way, the power button and pause button can be integrated into the display device, improving the integration level of the display device.

[0112] For example, a switch touch sensor and corresponding circuitry can be installed on the film layer by applying a film layer; and / or, a start / stop touch sensor and corresponding circuitry can be installed on the film layer.

[0113] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0114] 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.

[0115] 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 11 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.

[0116] For example, please refer to Figure 1 The display device also includes a light-diffusing sheet 35, which is disposed between the light-emitting side of the light source assembly 32 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.

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] For example, please refer to Figure 7 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.

[0122] 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.

[0123] For example, please refer to Figure 4 The knob assembly 1 includes a mounting component 13. 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.

[0124] It should be noted that you should refer to [link / reference]. Figure 1 The panel assembly 31 has a clearance hole 31a through which a portion of the mounting assembly 13 passes.

[0125] For example, please continue reading Figure 4 The knob assembly 1 includes an end cap 14, which is located radially inside the knob operation section 10 and is disposed on the axial side of the mounting assembly 13 away from the panel assembly 31. The second display screen 11" is disposed between the end cap 14 and the mounting assembly 13. The end cap 14 serves as the outer surface of the knob assembly 1.

[0126] It should be noted that the area of ​​the end cap 14 to be used for display is a light-transmitting part, while the other 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 jointly defined by the end cap 14 and the second display screen 11" can be understood as the aforementioned second display part 11.

[0127] For example, please refer to Figure 3 and Figure 4A hollow cylindrical structure 311 is formed on the side of the panel assembly 31 facing the mounting bracket 33. The mounting bracket 33 has a through hole 33b, and the 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.

[0128] For example, please refer to Figures 12 to 14 The background color of the display interface of the first display screen 34, the background color of the display interface of the second display screen 11", and the color of the RGB light group 321 on the panel assembly 31 are coordinated.

[0129] The background color of the first display screen 34 and the color displayed on the panel assembly 31 by the RGB light group 321 can both be changed according to the change of the background color of the second display screen 11".

[0130] For example, please see Figure 12 The background color of the second display screen 11" (which can be understood as 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 screen 34 is also approximately red. For another example, please refer to... Figure 13 All three are roughly purple in color. Please refer to [link / reference]. Figure 14 All three are dark blue.

[0131] In the above embodiments, the three elements present a relatively harmonious and unified color tone, which is conducive to further improving the overall visual effect of the display device.

[0132] For example, the background of the display interface of the first display screen 34 is coordinated with the background of the display interface of the second display screen 11".

[0133] It should be noted that background coordination can include background color coordination and / or graphic coordination and / or background animation coordination.

[0134] The background can be, for example, the color of the most eye-catching, largest, or most meaningful part of the display interface, such as the image or animation color. For instance, the overall background color (or animation) of the second display 11" can be used as a reference part, and the background color (or animation) of the first display 34 can be coordinated with the reference part.

[0135] In this way, the overall visual appeal of the first display screen 34 and the second display screen 11" can be further enhanced. The first display screen 34 and the second display screen 11" together display visually coherent images or animations, which can also be understood as screen-to-screen dynamic effects, so as to form a visually coordinated, unified or visually contrasting display effect, resulting in a better visual effect.

[0136] Background coordination includes, but is not limited to, one or more of the following: the image displayed on the first display unit 2 and the image displayed on the first display unit 11 constitute a complete image; graphics or animations move dynamically and coherently on the first display unit 2 and the second display unit 11, and the visuals are coherent animations.

[0137] For example, background coordination includes graphic coordination, where the graphics on the first display screen 34 and the graphics on the second display screen 11" can move continuously between the first display screen 34 and the second display screen 11"; or, the first display screen 34 and the second display screen 11" can collaboratively display different parts of the same dynamic image, i.e., the same image, with one part displayed on the first display screen 34 and the other part displayed on the second display screen 11" and the first display screen 34 and the second display screen 11" constitute a complete image.

[0138] For example, the display screen 34 can be continuously moved from the edge of the first display screen 34 near the knob assembly 1 to the second display screen 11 for display. For example, please refer to Figure 7 When the following functional items and the following graphic sub-area 2a are continuously moved on the first display screen 34, the part of the graphic that disappears from the first display screen 34 will be displayed on the second display screen 11". In this way, the continuity of the picture can be presented, further enhancing the interaction and technological feel of the first display screen 34 and the second display screen 11", and improving the visual effect.

[0139] For example, the first display screen 34 is used to display a first interface, wherein the first interface includes a plurality of selectable functional items. It should be noted that the first display screen 34 can display the first interface at any time; the first display screen 34 can display different interfaces under different conditions. Similarly, the second display screen 11" can display different interfaces under different conditions.

[0140] Functional items can be displayed in text and / or graphic form; there are no restrictions on this. For example, please refer to... Figures 8 to 10 , Figures 12 to 14 In some specific implementations, functional items are displayed in text form.

[0141] The specific content of the functional items on the first interface can be set according to the functions of home appliances.

[0142] 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.

[0143] 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.

[0144] For example, the display device includes a control unit, which responds to a selection command to select one of a plurality of function items on a first interface, causing the second display screen 11" to display the selected function item. In this embodiment, the user can intuitively see the function items to be selected on the first interface and can see the currently selected function item on the second display screen 11", which facilitates a prominent prompt to the user; in addition, the interaction between the first display screen 34 and the second display screen 11" is enhanced, which helps to improve the user experience.

[0145] It should be noted that the first display screen 34 displays the selectable function items, while the second display screen 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 screen 11" is executed, and the program corresponding to the selectable function item on the first display screen 34 is not executed.

[0146] For example, please refer to Figures 8 to 10 , Figures 12 to 14 The control unit is also used to display the remaining function items on the first display screen 34 when the selected function item is displayed on the second display screen 11". This allows the user to intuitively see which function items are available for selection in addition to the currently selected function item, and facilitates user operation if the user needs to reselect.

[0147] 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.

[0148] 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.

[0149] 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 screen 11" for display. When the knob operation unit 10 is rotated another 30°, the other function item moves to the second display screen 11" for display. If the knob operation unit 10 is rotated 60° continuously, the two function items are displayed sequentially on the second display screen 11", presenting a scrolling display effect. It can be understood that if the knob operation unit 10 is rotated 60° continuously at a very fast speed, the second display screen 11" may not have time to display the first selected function item and will directly display the second selected function item.

[0150] In other embodiments, the portion of the panel assembly 31 corresponding to the first display screen 34 includes a first touch-sensitive detection unit. The first touch-sensitive detection unit 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 screen 34 can move, and the movement of the function items is related to the sliding distance or the number of clicks.

[0151] 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 screen 34 is a touch screen as a whole.

[0152] In some embodiments, the end cap 14 includes a second touch-sensitive detection unit at the location corresponding to the second display screen 11". The second touch-sensitive detection unit inputs a selection command by detecting a sliding operation or a clicking operation performed on the second touch-sensitive detection unit.

[0153] The working principles of the first and second touch-sensitive detection units are the same, and will not be elaborated here.

[0154] 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 direction closest to the knob assembly 1, and the color protection wash function item leaves the first display screen 34 and moves to the second display screen 11". If the first touch-sensitive detection unit is clicked a second time, the silk function item leaves the first display screen 34 and moves to the second display screen 11". At this time, the second display screen 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 screen 11", it will automatically overwrite the previous function item displayed on the second display screen 11", and so on.

[0155] It should be noted that when the color protection wash function item leaves the first display screen 34, the next function item can be added to the first display screen 34.

[0156] For example, please refer to Figures 8 to 10 , Figures 12 to 14 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.

[0157] 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.

[0158] In other embodiments, please refer to Figure 13 The graphic sub-area 2a and the functional items located within it move synchronously when a selection command is input.

[0159] For example, with Figure 8 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 screen 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 8The displayed status is directly switched to Figure 9 The status is shown below.

[0160] For example, with Figure 12 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 13 The silk feature item moves from the second graphic sub-area 2a to the first graphic sub-area 2a, that is, from... Figure 12 The display shows the status and experience. Figure 13 The intermediate display state shown has been switched to... Figure 14 The status is shown below.

[0161] For example, each graphic sub-region 2a has the same shape and the same area.

[0162] 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.

[0163] For example, the area of ​​the second display screen 11" is larger than the area of ​​any graphic sub-area 2a. In this way, when the function item icon is moved to the second display screen 11", it has the effect of enlarging the screen and highlighting the key points.

[0164] For example, multiple graphic sub-regions 2a are arranged at intervals along a first direction.

[0165] 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.

[0166] This application provides a control method for a household appliance, which can be applied to any of the household appliances described above.

[0167] In some embodiments, please refer to Figure 15 The display control method includes the following steps S1 and S2.

[0168] S1. The first display unit 2 displays a first interface, which includes multiple selectable function items.

[0169] S2. 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 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.

[0170] 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.

[0171] For example, the 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.

[0172] 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.

[0173] For example, the start / stop operation area 3B described above inputs a start command by detecting the input operation applied to the start / stop operation area 3B.

[0174] 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.

[0175] 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.

[0176] For example, before the first display unit 2 displays the first interface, the 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.

[0177] 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.

[0178] For example, the aforementioned switch operation area 3A inputs a power-on command by detecting a pressing operation performed on the switch operation area 3A.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] For example, the display control method further includes matching the background image of the first display unit 2 with the background image of the second display unit 11 when the selected function item is displayed on 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.

[0183] In this embodiment, the background image includes at least one of color, pattern coherence, and animation coherence.

[0184] 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.

[0185] 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.

[0186] For example, prior to the steps before responding to the selection command, the 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.

[0187] 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.

[0188] Please see Figure 16 The following describes a method for controlling a household appliance according to a specific embodiment.

[0189] It should be noted that in standby mode, please refer to [link / reference]. Figure 11 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.

[0190] Step S31, in response to a power-on command. For example, the user presses the switch operation area 3A3A to input a power-on command.

[0191] 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.

[0192] The third display unit 3 lights up and displays the corresponding color. The boot screen can be an animated display or a static image.

[0193] 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.

[0194] 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.

[0195] 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.
