[0042] This application provides a display device. The display device can be used in household appliances.

[0043] 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.

[0044] There are no restrictions on the type of household appliances; for example, they can be cooking appliances, clothing processing equipment, etc.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] The garment treatment equipment can also be equipped with a steam unit for deodorizing, wrinkle removal and other care of garments.

[0049] The control motherboard is used to control the operation of the entire machine.

[0050] Please see Figures 1 to 5 The display device includes a first display unit 2, a second display unit 11, and a control unit.

[0051] 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.

[0052] For example, the first display unit 2 can also be used to play dynamic images.

[0053] The type of the first display unit 2 is not limited; for example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0054] For example, the second display unit 11 can also be used to play dynamic images.

[0055] The type of the second display unit 11 is not limited; for example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0056] 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 , Figure 5 In some specific implementations, functional items are displayed in text form.

[0057] The specific content of the functional items on the first interface can be set according to the functions of home appliances.

[0058] For garment processing equipment, the functional items are the main washing and care programs. These may include, for example, color protection wash, mixed wash, wool wash, anti-color bleeding wash, down jacket wash, bath towel wash, plush wash, steam wash, and mixed wash. It should be noted that different main washing and care programs differ in at least one aspect, such as the rotation speed of the garment drum, temperature, water volume, and washing duration, to allow for the use of different washing and care parameters based on the different materials of the garments.

[0059] 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.

[0060] The control unit is used to operate the screens of the first display unit 2 and the second display unit 11. For example, in some embodiments, the control unit may include a first circuit board and a second circuit board, wherein the first circuit board is used to operate the screens of the first display unit 2 and the second circuit board is used to operate the screens of the second display unit 11.

[0061] 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.

[0062] 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.

[0063] The control unit is used to respond to the selection command, causing the second display unit 11 to display the selected function item, and causing the first display unit 2 to display the remaining function items other than the selected function item, wherein the selection command includes selecting one of the multiple function items on the first interface.

[0064] For example, please see Figure 1The first interface displays four function items: color protection wash, mixed, wool, and anti-bleeding wash. If you select the color protection wash function, please refer to [link / reference]. Figure 2 If the color-protecting wash function leaves the first display unit 2, it will not be displayed on the first interface of the first display unit 2. Instead, it will be displayed on the second display unit 11, while the remaining blending, wool, and anti-bleeding wash functions will remain on the first interface. It should be noted that when the color-protecting wash function leaves the first display unit 2, other functions not currently displayed on the first interface can be added to it. For example, the aforementioned wool or steam wash functions can be added to the first interface. Figure 1 The display status shown has switched to Figure 2 The display status is shown below.

[0065] 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.

[0066] 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.

[0067] For example, when the first display unit 2 displays all function items except the selected function item, and the second display unit 11 displays the selected function item, the control unit is further configured to control the first display unit 2 and / or the second display unit 11 to switch display interfaces according to the start command of the home appliance. It should be noted that the start command of the home appliance refers to the start command that initiates the execution of the program corresponding to the function item. That is, when the second display unit 11 displays the currently selected function item, and the first display unit 2 displays the remaining function items, the home appliance can directly start the program corresponding to the currently selected function item displayed on the second display unit 11, making operation simple.

[0068] For example, if the second display unit 11 displays the color-protecting wash function and the first display unit 2 displays the other function items, and the user inputs a start command, the garment handling equipment will begin executing the washing and care program corresponding to the color-protecting wash function. At this time, the first display unit 2 and / or the second display unit 11 switch interfaces. For example, the first display unit 2 switches to an interface related to the color-protecting wash function, such as an interface displaying the washing and care progress of the color-protecting wash function. The second display unit 11 can also switch interfaces.

[0069] For example, please refer to Figures 1 to 3 , Figure 5 The display device includes a knob operation section 10, a second display section 11 located radially inner to the knob operation section 10, and a first display section 2 located radially outer to the knob operation section 10. In this way, the second display section 11 can fully utilize the space radially inner to the knob operation section 10 to display the currently selected function, which helps to improve the compactness of the display device's structural layout.

[0070] It should be noted that you should refer to [link / reference]. Figure 6 The knob operating part 10 has an appropriate extension length in the direction of its rotation axis for easy gripping by the user. That is, the knob operating part 10 is generally cylindrical. The annular circumferential outer surface is for the user to grip.

[0071] For example, both the second circuit board and the second display unit 11 are disposed radially inside the knob operation unit 10. This makes full use of the space radially inside the knob operation unit 10 and also facilitates the circuit arrangement between the second circuit board and the second display unit 11.

[0072] It is understandable that the second display unit 11 and the knob operation unit 10 can be components of the knob assembly 1.

[0073] For example, please refer to Figures 1 to 3 The first display unit 2 extends along a first direction, and the knob operation unit 10 is arranged adjacent to the first display unit 2 in the first direction. That is, the knob operation unit 10 is located at one end of the first display unit 2 in the first direction. Because the two are arranged adjacent to each other, it is beneficial to make the screens of the first display unit 2 and the second display unit 11 form a unified visual effect.

[0074] It should be noted that, taking the first direction as the left and right direction of the household appliance as an example, the knob operation part 10 can be located on the right side of the first display part 2 or on the left side of the first display part 2.

[0075] For example, please refer to Figures 1 to 5 The second display section 11 is circular and arranged concentrically with the knob operation section 10. This allows the shapes of the second display section 11 and the knob operation section 10 to match better, resulting in a better visual effect and better space utilization.

[0076] For example, please refer to Figures 1 to 3 , Figure 5 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. The indicator light ring 12 can illuminate when the household appliance is turned on, enhancing the visual effect of the display device.

[0077] 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.

[0078] 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.

[0079] For example, every time the knob operation unit 10 is rotated 30°, one of the function items on the first interface jumps to the second display unit 11 for display. When the knob operation unit 10 is rotated another 30°, the other function item jumps 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 two function items sequentially, presenting a scrolling display effect.

[0080] In other embodiments, the first display unit 2 includes a first touch-sensitive detection unit, which inputs selection commands by detecting sliding or clicking operations 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.

[0081] 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.

[0082] 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.

[0083] The working principles of the first and second touch-sensitive detection units are the same, and will not be elaborated here.

[0084] For example, multiple function items on the first interface are arranged along a first direction. The multiple function items on the first interface are used to move synchronously along the first direction when a selection command is input, and the first function item located in the movement direction is jumped to the second display unit 11 for display.

[0085] It should be noted that the function items can move continuously or in jumps on the first interface. For example, taking the function items of the aforementioned garment processing equipment as an example, if the first interface displays four function items, sequentially from the direction closest to the knob assembly 1 to the direction furthest from the knob assembly 1: Color Protection Wash, Mixed Wash, Wool Wash, and Anti-Color Bleeding Wash. When the first touch-sensitive detection unit is clicked for the first time, all four function items move synchronously towards the knob assembly 1, and the Color Protection Wash function item leaves the first display unit 2 and jumps to the second display unit 11 for display. If the first touch-sensitive detection unit is clicked a second time, the Mixed Wash function item leaves the first display unit 2 and jumps to the second display unit 11 for display. At this time, the second display unit 11 displays the Mixed Wash function item and does not display the Color Protection Wash function item. That is to say, when the next function item jumps to the second display unit 11 for display, it will automatically overwrite the function item previously displayed on the second display unit 11, and so on.

[0086] 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.

[0087] For example, please refer to Figures 1 to 3 , Figure 5 The first interface includes multiple graphic sub-areas 2a arranged along a first direction. Each graphic sub-area 2a is used to display a function item. The multiple function items on the first interface are used to jump synchronously among the multiple graphic sub-areas 2a when a selection command is input, and the position of the graphic sub-areas 2a remains unchanged.

[0088] For example, graphic sub-region 2a is circular.

[0089] For example, please see Figure 1 The first interface displays four graphic sub-areas side-by-side (2a). The color-protecting wash function is displayed in the first graphic sub-area (2a), the mixed function function in the second graphic sub-area (2a), the wool function function in the third graphic sub-area (2a), and the anti-color bleeding function function in the fourth graphic sub-area (2a). Please refer to [link / reference] when you first navigate to the interface. Figure 2 The color-protecting wash function jumps from the first graphic sub-area 2a to the second display section 11; the mixed function jumps from the second graphic sub-area 2a to the first graphic sub-area 2a; the wool function jumps from the third graphic sub-area 2a to the second graphic sub-area 2a; the anti-color bleeding function jumps from the fourth graphic sub-area 2a to the third graphic sub-area 2a; simultaneously, the down jacket function is displayed in the fourth graphic sub-area 2a, i.e., from... Figure 1 The displayed status has switched to Figure 2 The status is shown below. And so on.

[0090] 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.

[0091] For example, the various graphic sub-regions have the same shape and the same area.

[0092] Of course, in other embodiments, the area of ​​some graphic sub-regions may be larger than the area of ​​the other graphic sub-regions.

[0093] For example, the area of ​​the second display unit 11 is larger than the area of ​​any graphic sub-area 2a. Thus, when the function item icon jumps to the second display unit 11, it has the effect of enlarging the screen and highlighting key points.

[0094] For example, please refer to Figures 1 to 3 , Figure 5 The display device also includes a third display unit 3.

[0095] 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.

[0096] The switch operation area 3A detects pressing operations applied to it to input power-on or power-off commands for household appliances. The switch operation area 3A can also be understood as the on / off switch for the household appliance, also known as the power button.

[0097] The start / stop operation area 3B detects press operations applied to it to input start / stop commands for home appliances. The start / stop operation area can also be referred to as the pause button.

[0098] In this way, the power button and pause button can be integrated into the display device, improving the integration level of the display device.

[0099] For example, a power switch indicator is also present in the location of the switch operation area 3A. A start / stop button indicator is also present in the location of the start / stop operation area; please refer to [link / reference]. Figure 4 Even when the third display unit 33 is off, the power button and start / stop button indicators can still be identified, allowing users to quickly locate the power switch area 3A and the start / stop operation area 3B for easier operation. Of course, the power button and start / stop button indicators can also be identified when the third display unit 33 is in display mode.

[0100] For example, the third display unit 3, the first display unit 2, and the second display unit 11 are arranged adjacent to each other in the first direction, with the second display unit 11 located between the first display unit 2 and the third display unit 3. Thus, the third display unit 3, the first display unit 2, and the second display unit 11 are arranged in a generally elongated shape in the first direction. For example, arranging them in an elongated shape along the left-right direction on the front surface of a household appliance is beneficial for presenting an overall elongated visual display effect.

[0101] 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).

[0102] For example, please refer to Figure 6 The display device includes a mounting bracket 33 and a panel assembly 31. The mounting bracket 33 provides mounting support for other components of the display device, and the panel assembly 31 is disposed on the first side of the mounting bracket 33. The panel assembly 31 is generally flat, and when the display device is installed on the household appliance, the panel assembly 31 serves as the exterior surface of the display device and also constitutes part of the exterior surface of the household appliance.

[0103] For example, please refer to Figure 6 and Figure 8 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.

[0104] It should be noted that the area of ​​the panel assembly 31 used for display is a light-transmitting part, while another part can be light-shielded. The panel assembly 31 can transmit the display image of the first display screen 34 while also blocking other surrounding structures. For example, a touch sensor and circuit layer can be provided on the panel assembly 31 to realize touch control. That is to say, the display area defined by a part of the panel assembly 31 and the first display screen 34 can be understood as the aforementioned first display part 2.

[0105] For example, please refer to Figure 8 The knob assembly 1 includes a support structure 13, a second display screen 11", and an end cap 14. The support structure 13 is connected to the panel assembly 31. The knob operating part 13 surrounds the outer periphery of the support structure 13 and can rotate relative to the support structure 13. The end cap 14 is located radially inside the knob operating part 13 and is disposed on the axial side of the support structure 13 on the knob operating part 13. The second display screen 11" is disposed between the end cap 14 and the support structure 13.

[0106] The panel assembly 31 can protect the first display screen 34.

[0107] It should be noted that the area of ​​the panel assembly 31 used for display is the light-transmitting part, while another part can be light-shielded. The panel assembly 31 can transmit the display image of the second display screen 11" while also blocking other surrounding structures. For example, a touch sensor and circuit layer can be provided on the panel assembly 31 to realize touch control. That is to say, the display area defined by a part of the panel assembly 31 and the second display screen 11" can be understood as the aforementioned second display part 11.

[0108] For example, the mounting bracket 33 has a through hole 33b, through which a portion of the structure of the knob assembly 1 passes.

[0109] For example, please refer to Figure 6 and Figure 8 The mounting bracket 33 has a lamp cavity 33a, and the display device also includes an RGB lamp group 32. The RGB lamp group 32 is disposed in the lamp cavity 33a, and the panel assembly 31 at least covers the lamp cavity 33a. The light from the RGB lamp group 32 acts on the panel assembly 31, so that a portion of the panel assembly 31 defines the third display unit 3. The RGB lamp group 32 works by controlling the current of 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, without needing to present animations or other visuals. This helps reduce the cost of the third display unit 3.

[0110] 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.

[0111] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0112] 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.
