[0054] Of course, the laundry treatment apparatus can further be configured with an electrolysis assembly for electrolyzing water required for washing and treating clothes to achieve sterilization and color protection.

[0055] The laundry treatment apparatus can further be configured with a steam assembly for deodorizing and wrinkle removing clothes.

[0056] The control mainboard is used to control the operation of the whole machine.

[0057] Please refer to Figures 1 to 4 , the display device comprises a first display part 2, a second display part 3 and a knob assembly 1 arranged adjacent along a first direction, and the knob assembly 1 is located between the first display part 2 and the second display part 3.

[0058] It should be noted that, taking the left-right direction of the household appliance as the first direction, the second display part 3 can be located on the right side of the first display part 2, or on the left side of the first display part 2.

[0059] Exemplarily, the first display part 2 can be used to display dynamic pictures.

[0060] Exemplarily, at least part of the display background of the first display part 2 and at least part of the display background of the second display part 3 are coordinated.

[0061] It should be noted that, the coordination of the display background can include, for example, the coordination of background colors and / or the coordination of display graphics.

[0062] Exemplarily, the display background comprises background colors, and the background colors of the first display part 2 and the second display part 3 are matched. Here, the matching is mainly to make the background or display of the first display part 2 and the second display part 3 visually coordinated in color, so that the user feels comfortable in color, and the specific means is not limited.

[0063] Exemplarily, at least part of the display background of the first display part 2 can include the display of the whole background, or the display of part of the background, such as lines, patterns or images, etc.

[0064] In some embodiments, please refer to Figure 1 , the background color of the second display part 3 is red, and the color of the end of the first display part 2 close to the knob assembly is also red, except that the first display part 2 as a whole adopts a gradient color. Please refer to Figure 2, the color system of the background color of the second display part 3 is purple, and the color system of the end of the first display part 2 close to the knob assembly is also purple, but the first display part 2 as a whole adopts a gradient color. Please refer to Figure 3 , the color system of the background color of the second display part 3 is blue, and the color system of the end of the first display part 2 close to the knob assembly is also blue.

[0065] In the above embodiment, since the display background of the first display part 2 and the display background of the second display part 3 are coordinated, it is beneficial to further improve the overall display effect of the display device to form a coordinated, unified or visually strong contrast display effect.

[0066] It should be noted that the display background of the first display part 2 or the display background of the second display part 3 can be a solid color or a change. For example, when the first display part 2 displays a dynamic picture, the color of the most eye-catching or largest area or the image or animation with special meaning can be taken as a reference part, so that the display background of the second display part 3 is coordinated with the display background of the cover part. In some embodiments, when the first display part 2 displays part of the background, the background of the edge area of the second display part 2 can be included.

[0067] Exemplarily, the knob assembly 1 includes a knob operation ring 10 and a third display part 11 arranged radially inside the knob operation ring 10. It should be noted that the first display part 2 and the second display part 3 are both located radially outside the knob operation ring 10. The third display part 11 can fully utilize the space radially inside the knob operation ring 10 to display the interface, which is beneficial to improve the compactness of the structure layout of the display device.

[0068] Exemplarily, the third display part 11 can be used to play a dynamic picture.

[0069] Exemplarily, the display background of the third display part, the display background of the first display part, and the display background of the second display part are coordinated.

[0070] For example, please refer to Figure 1 , the color system of the background color of the second display part 3 and the third display part 11 is red, and the color system of the end of the first display part 2 close to the knob assembly 1 is also red, but the first display part 2 as a whole adopts a gradient color. Please refer to Figure 2 , the color system of the background color of the second display part 3 and the third display part 11 is purple, and the color system of the end of the first display part 2 close to the knob assembly is also purple, but the first display part 2 as a whole adopts a gradient color. Please refer to Figure 3 , the color system of the background color of the second display part 3 and the third display part 11 is blue, and the color system of the end of the first display part 2 close to the knob assembly 1 is also blue.

[0071] Exemplarily, the display pattern of the third display part 11 and the first display part are coordinated. The pattern of the first display part 2 can be continuously moved from the edge of the first display part 2 close to the third display part 11 to the third display part 11 for display; and / or, the pattern of the third display part 11 can be continuously moved from the edge of the third display part 11 close to the first display part 2 to the first display part 2 for display.

[0072] Please refer to Figure 2 When the display pattern moves between the first display part 2 and the third display part 11, the pattern is also coordinated at the edges of the first display part 2 and the third display part 11 close to each other. In this way, the display coordination and interactivity of the first display part 2 and the third display part 11 can be improved, the display device presents a better sense of technology, and the user experience is improved.

[0073] Exemplarily, the third display part 11 is circular, and the third display part 11 is concentrically arranged with the knob operating ring 10. In this way, the shapes of the third display part 11 and the knob operating ring 10 can be better matched, the display effect is better, and the space utilization is better.

[0074] Exemplarily, in the orthographic projection in the plane perpendicular to the axis of the knob assembly (which can also be understood as the orthographic projection in the plane where the first display part 2 is located), the outer periphery of the knob operating ring 10 has a first convex arc segment, the boundary of the first display part 2 has a first concave arc segment, and the first convex arc segment and the first concave arc segment coincide.

[0075] Please refer to Figure 6 and Figure 8 The arc line between the B1 arrow position and the B2 arrow position of the outer periphery of the knob operating ring 10 is the first convex arc segment, and the arc line between the B1 arrow position and the B2 arrow position of the boundary of the first display part 2 is the first concave arc segment.

[0076] In this way, the contour of part of the outer periphery of the knob operating ring 10 defines the display boundary of the first display part 2. Please refer to Figures 1 to 3 There is almost no non-display area gap between the knob operating ring 10 and the first display part 2, which is conducive to further improving the display connection effect between the first display part 2 and the knob operating ring 10 and the third display part 11.

[0077] It should be noted that the above-mentioned first display part 2, third display part 11, and second display part 3 refer to the area that can be displayed on the appearance (observed by the user).

[0078] Exemplarily, in the orthographic projection in the plane perpendicular to the axis of the knob operating ring 10, the outer periphery of the knob operating ring 10 has a second convex arc segment, the boundary of the second display part 3 has a second concave arc segment, and the second convex arc segment and the second concave arc segment coincide. Please refer to Figure 6 andFigure 8 The outer periphery of the knob operating ring 10 between the B3 arrow position and the B4 arrow position is a second convex arc segment, and the boundary of the second display part 3 between the B3 arrow position and the B4 arrow position is a second concave arc segment.

[0079] In this way, the contour of the part of the outer periphery of the knob operating ring 10 defines the display boundary of the second display part 3, and there is almost no non-display area gap between the knob operating ring 10 and the second display part 3, which is conducive to further improving the display connection effect between the second display part 3 and the knob operating ring 10 and the third display part 11.

[0080] Exemplarily, please refer to Figures 5 to 8 The second display part 3 is provided with a switch operating area 3A, and / or the second display part 3 is provided with an on / off operating area 3B.

[0081] The switch operating area 3A inputs the start instruction or the shutdown instruction of the household appliance by detecting the pressing operation acting on the switch operating area 3A. The switch operating area 3A can also be understood as the on key of the household appliance, and the on key can also be called the power key.

[0082] The on / off operating area 3B inputs the start instruction / stop instruction of the household appliance by detecting the pressing operation acting on the on / off operating area 3B. The on / off operating area 3B can also be called the pause key.

[0083] In this way, the on key and the pause key can be integrated in the display device, improving the integration of the display device.

[0084] Exemplarily, the on key mark is also provided at the position of the switch operating area 3A. The on / off key mark is also provided at the position of the on / off operating area 3B, please refer to Figure 4 Even in the case that the second display part 3 is turned off (the state of the household appliance in standby or shutdown), the on key mark and the on / off key mark can still be recognized, so that the user can quickly identify the positions of the switch operating area 3A and the on / off operating area 3B, and the operation is convenient. Of course, the on key mark and the on / off key mark can also be recognized when the second display part 3 is in a display state.

[0085] Exemplarily, please refer to Figures 1 to 3 、 Figures 5 to 8 An indicator light ring 12 is also provided between the knob operating ring 10 and the third display part 11. The indicator light ring 12 is located on the radially inner side of the knob operating ring 10 and surrounds the outer periphery of the third display part 11. Since the indicator light ring 12 is located between the first display part 2 and the knob operating ring 10, please refer to Figures 1 to 3When the first display part 2 displays a picture, the light of the indicator ring 12 can play a transition effect between the first display part 2 and the knob operating ring 10, and it is also beneficial to improve the layout rationality of the knob assembly 1.

[0086] The indicator ring 12 refers to an area for displaying a ring of light. That is, the user can see the indicator ring 12.

[0087] Exemplarily, the indicator ring 12 and the knob operating ring 10 are arranged radially apart from each other, and the spacing area between the indicator ring 12 and the knob operating ring 10 is a non-display area.

[0088] Exemplarily, the indicator ring 12 and the first display part 2 are arranged radially apart from each other, and the spacing area between the indicator ring 12 and the first display part 2 is a non-display area.

[0089] Exemplarily, referring to Figure 4 , in the off or standby state of the knob assembly 1, the above-mentioned non-display area and the color presented by the first display part 2 are substantially the same, for example, both are black. In this way, the appearance consistency in the off or standby state can be improved.

[0090] Exemplarily, referring to Figure 5 , the size D1 of the first display part 2 in the second direction is not less than the size D2 of the third display part 11 in the second direction, and not greater than the outer diameter D3 of the knob operating ring 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 operating ring 10 can be set to a size suitable for holding, and the display size of the third display part 11 in the second direction is between the size of the third display part 11 in the second direction and the outer diameter of the knob operating ring 10. In this way, the third display part 11 has a suitable size to match the knob operating ring 10, the overall size is more in line with ergonomics, and it is beneficial to improve the overall layout rationality and display effect of the display device.

[0091] Exemplarily, referring to Figure 5 , the outer diameter D of the third display part 11 is 1 / 3~2 / 3 of the outer diameter D3 of the knob operating ring 10. That is, D3*1 / 3≤D2≤D3*2 / 3. The size ratio of the third display part 11 and the knob operating ring 10 is relatively moderate and reasonable. In the case that the size of the knob operating ring 10 is convenient for the user to hold, the first display part 2 has a suitable area to display a picture.

[0092] In some specific embodiments, D3*1 / 2≤D2≤D3*2 / 3, and the third display part 11 has a larger area to display a picture.

[0093] Exemplarily, the first display part 2 and the second display part 3 have the same size in the second direction. In this way, the display coordination of the first display part 2 and the second display part 3 is better.

[0094] Exemplarily, referring to Figure 5 , the size W1 of the first display part 2 in the first direction is greater than the size W2 of the second display part 3 in the first direction. The size of the second display part 3 in the first direction is relatively short, and in the case that the installation space of the household appliance is unchanged, a larger size can be left for the first display part 2 to display the picture.

[0095] Exemplarily, the size of the first display part in the first direction is 2-5 times, for example, 2 times, 3 times, 4 times, 5 times, of the length of the second display part in the first direction. In this way, in the case that the size of the display device is determined, the second display part has a relatively large display area to display the relevant information.

[0096] Exemplarily, the outline formed by the first display part 2 and the second display part 3 is substantially rectangular, but it should be noted that the long side of the rectangle is discontinuous and is disconnected at the knob assembly 1.

[0097] The size of the rectangle in the first direction is greater than the size in the second direction, and the outer diameter of the knob assembly 1 is greater than the size of the rectangle in the second direction, wherein the first direction and the second direction are perpendicular. That is, the parts on the opposite sides of the knob assembly 1 in the second direction exceed the edges of the rectangle in the second direction. It can also be understood that the outer diameter of the knob assembly 1 is greater than the size of the first display part 2 in the second direction, and the outer diameter of the knob assembly 1 is greater than the size of the second display part 3 in the second direction. In this way, the knob assembly 1 has a larger outer diameter for the user to hold.

[0098] Exemplarily, referring to Figure 5 , the size D1 of the first display part 2 in the second direction does not exceed the outer diameter D4 of the indicator light ring 12. In this way, the outer diameter of the indicator light ring 12 is relatively large, and a better display transition effect is achieved.

[0099] The first display part 2 is used to display a first interface, and the first interface includes a plurality of function items that can be selected. It should be noted that the timing of the first display part 2 displaying the first interface is not limited, and the first display part 2 can display different interfaces under different conditions.

[0100] The function items can be displayed in the form of text and / or graphics, which is not limited here. For example, referring to Figures 1 to 3 , Figures 6 to 8 , in some specific embodiments, the function items are displayed in the form of text.

[0101] The specific content of the function item on the first interface can be set according to the function of the household appliance.

[0102] For the laundry treatment device, the function item is a washing and caring main program of the laundry treatment device, which can include, for example, color protection washing, silk, wool, anti-color bleeding, down jacket, bath towel, plush, steam washing, silk washing, and the like. It should be noted that different washing and caring main programs differ in at least one of the rotation speed of the laundry treatment drum, the temperature, the water consumption, the washing and caring time length, and the like, and are used to adopt different washing and caring parameters according to different materials of the laundry.

[0103] It should be noted that all the function items of the household appliance do not have to be displayed on the first interface at the same time. For example, if the washing and caring main program of the laundry treatment device has seven, but when the number of function items displayed on the first interface at each time is less than seven, the other function items can be displayed on the first interface as needed in a cyclic manner.

[0104] The display device includes a control portion for running the screens of the first display portion 2 and the third display portion 11. For example, in some embodiments, the control portion can include a first circuit board for running the screen of the first display portion 2 and a second circuit board for running the screen of the third display portion 11.

[0105] It should be noted that the first circuit board (or the second circuit board) not only includes a hard board, but also includes circuits, electronic components, and the like integrated on the hard board.

[0106] Exemplarily, 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 portion 2 and the third display portion 11 can display the screen in coordination.

[0107] The control portion is used for a selection instruction corresponding to selecting one of the plurality of function items on the first interface, so that the third display portion 11 displays the selected function item.

[0108] It should be noted that the first display portion 2 displays a function item to be selected, and the third display portion 11 displays a currently selected function item. When the household appliance is started (that is, when a start instruction is input), the program corresponding to the currently selected function item displayed by the third display portion 11 is executed, and the program corresponding to the function item to be selected on the first display portion 2 is not executed.

[0109] It should be noted that the display background of the first display portion 2 is different for different currently selected function items of the third display portion 11, and the display background of the first display portion 2, the display background of the second display portion 3, and the display background of the third display portion 11 are coordinated according to the background of the currently selected function item.

[0110] In the related art, when the function item on the first display part 2 needs to be displayed on the third display part 11, a further confirmation operation is needed after the selection icon is moved to the corresponding function item to be selected, which is complicated.

[0111] In the embodiment of the present application, when the function item on the first interface of the first display part 2 is moved to the third display part 11 to be displayed as the currently selected function item, the operation is convenient.

[0112] The display device of the embodiment of the present application can intuitively show the function item to be selected on the first interface and the currently selected function item on the third display part 11, which is convenient for attracting the user's attention and enhancing the interaction between the first display part 2 and the third display part 11, thereby improving the user experience.

[0113] Exemplarily, please refer to Figures 1 to 3 , Figures 6 to 8 , the control part is further configured to display the rest of the function items except the selected function item on the first display part 2 when the selected function item is displayed on the third display part 11. In this way, the user can intuitively see which function items are to be selected in addition to the currently selected function item, and if the user needs to reselect, the user can operate conveniently.

[0114] Exemplarily, the control part is further configured to move the multiple function items on the first interface synchronously in response to the selection instruction, and move one or more of the multiple function items from the first display part 2 to the third display part 11 in the moving direction, and the third display part 11 is configured to display the currently selected function item.

[0115] It should be noted that the one or more of the multiple function items are moved from the first display part 2 to the third display part 11 in the moving direction, which means that if the single input selection instruction only moves one function item from the first display part 2 to the third display part 11, only one function item leaves the first display part 2 and moves to the third display part 11. If the single input selection instruction moves multiple function items from the first display part 2 to the third display part 11, the multiple function items leave the first display part 2 in sequence and are displayed on the third display part 11 in sequence, but the last function item moves to the third display part 11 and the previous function item leaves the third display part 11. For example, please refer to Figure 6 , four function items are displayed on the first interface, which are color protection washing, silk, wool, and color protection, and if the selected instruction selects the color protection washing function item, please refer to Figure 7The color protection washing function item moves away from the first display part 2, i.e., the first interface of the first display part 2 does not display the color protection washing function item, and the color protection washing function item moves to the third display part 11 for display. It should be noted that when the color protection washing function item moves away from the first display part 2, other function items that are not displayed on the first interface can be additionally displayed on the first interface, for example, the above-mentioned quick washing function item can be additionally displayed on the first interface. That is, from the display state shown in FIG. 8A, the first interface of the first display part 2 switches to the display state shown in FIG. 8B. Figure 6 Figure 7

[0116] In this embodiment, the input selection instruction can cause the plurality of function items on the first interface to move synchronously, for example, can move along a straight path, can move along a curved path, form an overall sliding effect, and the display effect and human-computer interaction are better.

[0117] Exemplarily, the plurality of function items move synchronously in the first direction when the input selection instruction is input. For example, the third display part 11 is located at the first end of the first display part 2 in the first direction, and the plurality of function items move synchronously in the first direction, which can be moving towards the third display part 11 or moving away from the third display part 11.

[0118] In some embodiments, the plurality of function items can only move synchronously in the first direction and towards the third display part 11, and cannot move synchronously away from the third display part 11. In other embodiments, the plurality of function items can only move synchronously in the first direction and away from the third display part 11, and cannot move synchronously towards the third display part 11. In yet other embodiments, according to the direction of the selection instruction, the plurality of function items can move synchronously in the first direction and towards the third display part 11, and can also move synchronously away from the third display part 11.

[0119] It should be noted that the names of the function items in the above embodiments of the present application are described by taking the washing machine as an example. The laundry treatment equipment of the embodiments of the present application can also be a dryer or a washing-drying integrated machine. For different types or different models of laundry treatment equipment, the names of the function items are adaptively changed according to the main programs required by the laundry treatment equipment. For example, the function items for the dryer can be steam washing, fast drying, odor removal, etc., which are not limited herein.

[0120] It should be noted that before the function items on the first interface move to the third display part 11, the interface displayed on the third display part 11 is not limited, for example, the start-up interface of the third display part 11 can include a default function item.

[0121] ​​The inputting of the selection instruction is not limited, for example, remote control input (for example, a small program on a mobile phone is used to remotely input, or a remote controller is used to remotely input), key input, voice input, etc., which are not limited herein.

[0122] For example, in some embodiments, the knob operating ring 10 inputs the selection instruction by rotating. Specifically, the rotation angle of the knob operating ring 10 can be detected by the detection structure, and the rotation angle of the knob operating ring 10 is associated with the function item on the first interface, and the selection instruction can be input based on the rotation angle of the knob operating ring 10.

[0123] For example, the knob operating ring 10 rotates by 30°, and one of the function items on the first interface moves to the third display part 11 to be displayed. When the knob operating ring 10 rotates by another 30°, another function item moves to the third display part 11 to be displayed. If the knob operating ring 10 continuously rotates by 60°, the two function items are displayed on the third display part 11 in sequence, which presents a scrolling display effect. It can be understood that if the knob operating ring 10 continuously rotates by 60° at a very fast speed, the third display part 11 may not have enough time to display the first selected function item, and directly displays the second selected function item.

[0124] In some other embodiments, the first display part 2 includes a first touch-sensitive detection part, and the first touch-sensitive detection part inputs the selection instruction by detecting a sliding operation or a clicking operation acting on the first touch-sensitive detection part. Specifically, for example, when the user slides or clicks on the surface of the first touch-sensitive detection part, the function item on the first interface of the first display part 2 can have a moving effect, and the moving effect of the function item is related to the sliding distance or the number of clicks.

[0125] The first touch-sensitive detection part can be a specified area on the first interface, or the entire first interface can be used as the first touch-sensitive detection part, for example, the first display part 2 is a touch screen.

[0126] In some embodiments, the third display part 11 includes a second touch-sensitive detection part, and the second touch-sensitive detection part inputs the selection instruction by detecting a sliding operation or a clicking operation acting on the second touch-sensitive detection part.

[0127] The working principles of the first touch-sensitive detection part and the second touch-sensitive detection part can be the same, which will not be repeated here.

[0128] It should be noted that the function items can be moved continuously or jumpingly on the first interface. For example, taking the function items of the clothes treatment device as an example, assuming that the first interface displays four function items, from the direction close to the knob assembly 1 to the direction far from the knob assembly 1, the four function items are color protection washing, silk, wool, and color protection, respectively. When the first touch-sensitive detection portion is clicked for the first time, the four function items are moved synchronously towards the direction close to the knob assembly 1, and the color protection washing function item is moved away from the first display portion 2 and displayed on the third display portion 11. If the first touch-sensitive detection portion is clicked for the second time, the silk function item is moved away from the first display portion 2 and displayed on the third display portion 11, at this time, the third display portion 11 displays the silk function item and does not display the color protection washing function item, that is, when the next function item is moved to the third display portion 11 for display, the last function item displayed on the third display portion 11 is automatically covered, and so on.

[0129] It should be noted that when the color protection washing function item is moved away from the first display portion 2, the next function item can be displayed on the first display portion 2.

[0130] Exemplarily, referring to Figures 1 to 3 , Figures 6 to 8 , the first interface includes a plurality of graphic sub-regions 2a, each of which is used to display a function item. For example, the graphic sub-regions 2a are circular.

[0131] In some embodiments, the plurality of function items are used to move synchronously in the plurality of graphic sub-regions 2a when a selection instruction is input, and the positions of the graphic sub-regions 2a remain unchanged.

[0132] In other embodiments, the graphic sub-regions 2a and the function items located in the graphic sub-regions 2a move synchronously when a selection instruction is input.

[0133] For example, taking the display state shown in Figure 6 as an example, the first interface displays four graphic sub-regions 2a side by side, the color protection washing function item is displayed in the first graphic sub-region 2a, the silk function item is displayed in the second graphic sub-region 2a, the wool function item is displayed in the third graphic sub-region 2a, and the color protection function item is displayed in the fourth graphic sub-region 2a. When moved for the first time, the color protection washing function item is moved from the first graphic sub-region 2a to the third display portion 11, the silk function item is moved from the second graphic sub-region 2a to the first graphic sub-region 2a, the wool function item is moved from the third graphic sub-region 2a to the second graphic sub-region 2a, and the color protection function item is moved from the fourth graphic sub-region 2a to the third graphic sub-region 2a, at the same time, the quick washing function item is displayed in the fourth graphic sub-region 2a, that is, the display state shown in Figure 6 is directly switched to the display state shown in Figure 7 .

[0134] 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.

[0135] For example, each graphic sub-region 2a has the same shape and the same area.

[0136] 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.

[0137] For example, the area of ​​the third display unit 11 is larger than the area of ​​any graphic sub-area 2a. Thus, when a function item icon is moved to the third display unit 11, it has the effect of enlarging the screen and highlighting key points.

[0138] For example, multiple graphic sub-regions 2a are arranged at intervals along a first direction.

[0139] 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 operation ring 10 is located on the side of the panel assembly 31 away from the mounting bracket 33.

[0140] 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.

[0141] 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.

[0142] It should be noted that the area of the panel assembly 31 required for display is the light-transmissive part, and the other part can be light-shielded. The panel assembly 31 can transmit the display of the first display screen 34 and shield other structures in the periphery. For example, the panel assembly 31 can be provided with a touch sensor and a circuit layer for realizing touch control.

[0143] The light of the first display screen 34 transmits through the panel assembly 31 to define the first display part 2 in a part of the panel assembly 31.

[0144] For example, in the orthographic projection of the plane perpendicular to the axial direction of the knob operating ring 10, the projection of the knob assembly 1 has an overlapping area with the first display screen 34, that is, a part of the knob operating ring 10 is superimposed on the side of the first display screen 34 facing the appearance surface. The light of the first display screen 34 located outside the overlapping area transmits through the panel assembly 31 to define the first display part 2 in a part of the panel assembly 31.

[0145] In this embodiment, the knob operating ring 10 blocks a part of the display area of the first display screen 34, and the display area of the first display screen 34 blocked by the knob operating ring 10 is not exposed to the appearance surface of the display device, that is, the user cannot see the area of the first display screen 34 blocked by the knob operating ring 10. In this way, the part of the peripheral contour of the knob operating ring 10 can serve as the boundary of the first display part 2, so that the appearance of the knob operating ring 10 and the first display part 2 is more coordinated and / or better matched. In addition, the first display screen 34 can adopt a rectangular regular shape, and does not need to adopt a special-shaped form, which is beneficial to reducing the cost and manufacturing difficulty of the first display screen 34.

[0146] For example, referring to Figure 11 and Figure 12 , the knob assembly 1 comprises a mounting assembly 13, a second display screen 11" and an end cover 14. The mounting assembly 13 is connected with the panel assembly 31, and the knob operating ring 10 is wrapped around the outer periphery of the mounting assembly 13 and can rotate relative to the mounting assembly 13. The knob assembly 1 is connected to the panel assembly 31 through the mounting assembly 13. That is, the panel assembly 31 provides mounting support and positioning for the knob assembly 1.

[0147] It should be noted that referring to Figure 9 , the panel assembly 31 has a clearance hole 31a, and a part of the mounting assembly 13 passes through the clearance hole 31a.

[0148] The end cover 14 is located radially inside the knob operating ring 10, and the end cover 14 is arranged on the axial side of the mounting assembly 13, and the second display screen 11" is arranged between the end cover 14 and the mounting assembly 13. The end cover 14 serves as the appearance surface of the knob assembly 1.

[0149] 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 third display part 11.

[0150] 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.

[0151] 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.

[0152] For example, the mounting bracket 33 has a through hole 33b, through which a portion of the structure of the knob assembly 1 passes.

[0153] For example, the display device includes an RGB light group 321 and a mounting bracket 33 having a lamp cavity 33a; the RGB light group 321 is disposed in the lamp cavity 33a, and the panel assembly 31 at least covers the lamp cavity 33a; the light from the RGB light group 321 passes through the panel assembly 31 to define a second display section 3 in a portion of the panel assembly 31.

[0154] For example, the RGB light group 321 is disposed on the RGB circuit board 322.

[0155] 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 second 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 second display unit 3.

[0156] 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.

[0157] The touch sensor can be a resistive touch sensor, a capacitive touch sensor, etc., and there are no restrictions here.

[0158] 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.

[0159] Exemplarily, please refer to Figure 9 , the display device further comprises a light homogenizing sheet 35, which is arranged between the light-emitting side of the lamp group and the corresponding panel assembly 31, and is used for homogenizing the light so as to make the light more uniform and soft.

[0160] Exemplarily, the color system of the background color of the second display part 3, the background color of the first display part 2 and the background color of the third display part 11 is the same. For example, please refer to Figure 1 , the background color of the third display part 11 is red, the color presented by the RGB lamp group 321 on the panel assembly 31 is also red, and the background color of the first display part 2 is also approximately red. For another example, please refer to Figure 2 , the colors of the three are approximately purple. Please refer to Figure 3 , the colors of the three are dark blue. In the above embodiments, the three present a relatively coordinated and unified color tone, which is beneficial to further improving the overall display effect of the display device.

[0161] Exemplarily, in the vertical projection of the plane perpendicular to the axial direction of the knob operating ring 10, the projection of the knob operating ring 10 has an overlapping area with the lamp cavity 33a. In this embodiment, the knob operating ring 10 blocks the light projected by the lamp group to the panel assembly 31, and the light blocked by the knob operating ring 10 does not appear on the appearance surface of the display device, that is, the user cannot see the area blocked by the knob operating ring 10. In this way, part of the peripheral contour of the knob operating ring 10 can serve as the boundary of the second display part 3, so that the appearance coordination and / or matching of the knob operating ring 10 and the second display part 3 is better.

[0162] Exemplarily, please refer to Figure 9 and Figure 12 , the panel assembly 31 is formed with a hollow cylindrical structure 311 on the side facing the mounting bracket 33, please refer to Figure 13 and Figure 14 , the mounting bracket 33 has a through hole 33b, and the cylindrical structure 311 is arranged in the through hole 33b. Part of the mounting assembly 13 is accommodated in the cylindrical structure 311 and connected with the cylindrical structure 311. The cylindrical structure 311 can improve the connection reliability of the panel assembly 31 and the mounting assembly 13, and the use of the through hole 33b to accommodate the cylindrical structure 311 facilitates the positioning of the panel assembly 31 and reduces the probability of relative movement of the panel assembly 31 and the mounting bracket 33.

[0163] The display control method provided by the embodiments of the present application can be applied to the household appliance of any of the above embodiments.

[0164] In some embodiments, please refer to Figure 12 , the display control method comprises the following steps S1 and S2.

[0165] S1, based on the start-up instruction of the household appliance. For example, the switch operation area 3A described above inputs the start-up instruction by detecting the operation on the switch operation area 3A.

[0166] S2, controlling the display background of the first display part 2 and the second display part 3 located on the opposite sides of the knob assembly 1 in the first direction to be coordinated.

[0167] In this way, the background of the display interface of the first display part 2 and the background of the display interface of the second display part 3 are coordinated and unified, which is conducive to improving the overall display effect of the display device.

[0168] In some embodiments, the display control method further includes: causing the first display part 2 to display a first interface, the first interface including a plurality of selectable function items; and causing the third display part 11 of the knob assembly 1 to display a currently selected one of the plurality of function items based on a selection instruction selecting one of the plurality of function items on the first interface. 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 third display part 11. In addition, the interaction between the first display part 2 and the third display part 11 is enhanced, which is conducive to improving the user experience.

[0169] For example, the display control method further includes: in the case where the third display part 11 displays the currently selected one of the function items, causing the household appliance to execute a program corresponding to the function item displayed on the third display part 11 based on a start-up instruction of the household appliance.

[0170] In this embodiment, that is, in the case where the third display part 11 displays the currently selected function item and the first display part 2 displays the first interface, the household appliance can directly start the program corresponding to the currently selected function item displayed on the third display part 11, which is simple to operate.

[0171] For example, the start / stop operation area 3B described above inputs the start-up instruction by detecting the pressing operation on the start / stop operation area 3B.

[0172] For example, the display control method further includes: in the case where the third display part 11 displays the currently selected one of the function items, causing the household appliance to execute a program corresponding to the function item displayed on the third display part 11 based on a start-up instruction of the household appliance.

[0173] It should be noted that the start-up interface in the embodiments of the present application refers to the interface displayed on the display part after the start-up instruction is input and the household appliance is started without the need for user intervention.

[0174] For example, before the first display unit 2 displays the first interface, the display control method further includes: causing the first display unit 2 to display a power-on interface based on a power-on command of a household appliance. The step of causing the first display unit 2 to display the first interface includes: switching the first display unit 2 from the power-on interface to the first interface based on a first interface wake-up command.

[0175] 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.

[0176] For example, a wake-up command can be input by turning the knob on the ring 10, touching the first display unit 2, or touching the third display unit 11.

[0177] For example, the display control method includes: when the third display unit 11 displays the selected function item, the first display unit 2 displays the remaining function items other than the selected function item.

[0178] 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.

[0179] For example, prior to the steps based on the selection command, the display control method further includes: based on the power-on command of the household appliance, causing the third 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 third display unit 11. Thus, if the user currently needs to use the default function item, they can directly input the start command, making the operation simpler and more convenient.

[0180] The default function items on the third 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 third display unit 11 remain the same 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.

[0181] Exemplarily, the display backgrounds of the first display part 2 and the second display part 3 located on opposite sides of the knob assembly 1 in the first direction are coordinated, including: coordinating the background color of the first display part 2, the background color of the second display part 3, and the background color of the third display part 11 of the knob assembly. In this way, the three display parts present a relatively coordinated and unified color tone, which is beneficial to further improving the overall display effect of the display device.

[0182] Please refer to Figure 13 The display control method of the household appliance in a specific embodiment is described below.

[0183] It should be noted that in the standby state, please refer to Figure 4 The first display part 2, the third display part 11, and the second display part 3 will not display, and the whole generally presents black. The on key mark and the start / stop key mark on the second display part 3 are visible.

[0184] Step S31, based on the power-on instruction. For example, the user presses the switch operation area 3A to input the power-on instruction.

[0185] Step S32, after power-on, the first display part 2 and the third display part 11 display respective power-on interfaces. The power-on interface of the third display part 11 includes a default function item.

[0186] The second display part 3 is brightened and presents a corresponding color. The power-on interface can be an animated display or a static picture.

[0187] Step S33, based on the first interface wake-up instruction, the first display part 2 is switched from the power-on interface to the first interface, wherein the first interface includes a plurality of selectable function items.

[0188] Step S34, based on the selection instruction, the plurality of function items on the first interface are synchronously moved, and one or more of the plurality of function items are moved from the first display part 2 to the third display part 11 along the moving direction for display, and the third display part 11 is used to display the currently selected function item. For example, the knob operation ring 10 can be rotated, or the first display part 2 can be swiped or clicked, or the third display part 11 can be swiped or clicked, until the desired function item is displayed on the third display part 11. At this time, the remaining function items are still displayed on the first interface of the first display part 2.

[0189] Step S35, based on the start instruction, the household appliance executes a program corresponding to the function item currently displayed by the third display part 11.

[0190] It should be noted that the background of the display interface of the first display part 2 and the background of the display interface of the third display part 11 can be displayed in coordination in any one of the above method steps.
