[0048] Please refer to Figure 1 and Figure 2 , the knob operation part 10 surrounds the outer periphery of the support structure 13 and can rotate relative to the support structure 13. It can be understood that the knob operation part 10 can rotate relative to the shell. For example, the knob operation part 10 rotates under the twisting operation of the user, and in addition, the support structure 13, the first display part 11 and the ring-shaped display part 12 do not rotate with the knob operation part 10 in the rotation process of the knob operation part 10.

[0049] Exemplarily, the knob operation part 10 can realize the selection of a program or the adjustment of a parameter and the like in the rotation process.

[0050] Please refer to Figure 10 , the first display part 11 is used for displaying a picture.

[0051] Please refer to Figure 1 and Figure 2 , the first display part 11 is located on the radial inner side of the knob operation part 10, that is, the knob operation part 10 surrounds the outer periphery of the first display part 11.

[0052] Please refer to Figure 1 , the ring-shaped display part 12 surrounds the outer periphery of the first display part 11 and is located on the radial inner side of the knob operation part 10, and the ring-shaped display part 12 is used for guiding light to the outside view of the knob assembly 1. That is, in the radial direction of the knob operation part 10, the ring-shaped display part 12 is located between the knob operation part 10 and the first display part 11.

[0053] The ring-shaped display part 12 refers to an area for displaying a ring of bright light. That is, the user can see the ring-shaped display part 12.

[0054] The knob assembly of the embodiment of the present application, since the annular display part 12 is located between the first display part 11 and the knob operation part 10, please refer to Figure 10 When the first display part 11 displays a picture, the bright light of the annular display part 12 can play a visual transition effect between the first display part 11 and the knob operation part 10, which is also conducive to improving the layout rationality of the knob assembly 1.

[0055] Exemplarily, please refer to Figure 1 The annular display part 12 and the knob operation part 10 are radially spaced apart, please refer to Figure 10 The spacing area between the annular display part 12 and the knob operation part 10 is a non-display area.

[0056] Exemplarily, please refer to Figure 1 The annular display part 12 and the first display part 11 are radially spaced apart, and the spacing area between the annular display part 12 and the first display part 11 is a non-display area.

[0057] Exemplarily, in the off or standby state of the knob assembly, the non-display area and the first display part 11 present the same color, for example, both are black. In this way, the appearance consistency in the off or standby state can be improved.

[0058] It should be noted that the above-mentioned position relationship of the annular display part 12, the knob operation part 10 and the first display part 11 in the radial direction is the appearance projection in the plane of the first display part 11, which can also be understood as the position relationship of the three observed by the user on the appearance of the knob assembly.

[0059] The specific contour shape of the first display part 11 is not limited, for example, it can be an oval, a polygon, etc.

[0060] Exemplarily, please refer to Figure 1 and Figure 10 The first display part 11 is circular, the annular display part 12 is circular ring-shaped, and the first display part 11, the annular display part 12 and the knob operation part 10 are concentrically arranged. In this way, the overall layout is relatively reasonable, and the appearance consistency is good. It should be noted that the above-mentioned shape refers to the shape of the orthographic projection in the plane perpendicular to the rotation axis of the knob operation part 10.

[0061] It should be noted that the knob operation part 10 has a proper extension length on its rotation axis, which is convenient for the user to hold. That is, the knob operation part 10 is substantially cylindrical. The circumferential outer surface of the circular ring shape is used for the user to hold.

[0062] Exemplarily, please refer to Figure 1In the case that the first display part 11 is circular, the outer diameter D1 of the first display part 11 is 1 / 3-2 / 3 of the inner diameter D2 of the knob operation part 10, i.e. D2*1 / 3≤D1≤D2*2 / 3. The size ratio of the first display part 11 and the knob operation part 10 is moderate and reasonable, and in the case that the size of the knob operation part 10 is convenient for the user to hold, the first display part 11 has a proper area to display the picture.

[0063] In some embodiments, D2*1 / 2≤D1≤D2*2 / 3, and the first display part 11 has a larger area to display the picture.

[0064] Exemplarily, the annular display part 12 comprises a light emitting structure 14 and an annular light emitting area, the annular light emitting area surrounds the outer periphery of the first display part 11, and the annular light emitting area is used to guide the light emitted by the light emitting structure 14 to the outside field of view of the knob assembly 1. The light emitting structure 14 serves as a light source to generate the required light. The annular light emitting area refers to the light emitting position of the light emitting structure 14, from which the light exits the knob assembly 1.

[0065] It should be noted that in the appearance projection of the plane where the first display part 11 is located, the appearance profile of the annular display part 12 and the appearance profile of the annular light emitting area are the same.

[0066] In the related art, a plurality of lamp beads are arranged inside the light emitting position of the annular display part, the area between two adjacent lamp beads has a lower brightness, the lamp beads have a higher brightness, and the user can observe the graininess presented by the lamp beads, which affects the appearance.

[0067] Therefore, in some embodiments of the present application, in the orthographic projection of the plane where the first display part 11 is located, the light emitting structure 14 and the annular light emitting area do not overlap, and the support structure 13 blocks the light emitting structure 14. In this way, the light emitting structure 14 is blocked by the support structure 13 and cannot be observed from the appearance surface of the knob assembly 1, which is conducive to improving the graininess of the lamp beads in the related art.

[0068] In some embodiments, please refer to Figure 2 and Figure 3 The knob assembly 1 comprises a circuit board 15, the light emitting structure 14 comprises a plurality of RGB lamp beads 141 arranged on the circuit board 15, and the plurality of RGB lamp beads 141 are arranged at intervals along the circumferential direction of the annular light emitting area on the circuit board 15. The circuit board 15 is used to control the light emitting color of the plurality of RGB lamp beads 141. The working principle of the RGB lamp bead 141 is to change the brightness by controlling the current size of the red, green and blue lamp beads, and then to realize the color effect by combining different colors.

[0069] In this embodiment, the RGB lamp beads 141 are driven and controlled by the circuit board 15, which can realize the diversification of the appearance color of the annular display part 11.

[0070] It should be noted that the specific number of RGB lamp beads 141 is not limited.

[0071] The specific form of the circuit board 15 is not limited, for example, the circuit board 15 is substantially circular, facilitating assembly in the knob operating part 10.

[0072] The specific type of the first display part 11 is not limited, for example, it can be an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0073] The first display part 11 can be partially a touch-sensitive screen, and the remaining part constitutes a non-touch-sensitive screen. The first display part 11 can also be entirely a touch-sensitive screen. The touch-sensitive screen can also be referred to as a sensor screen or a touch screen.

[0074] Exemplarily, the first display part 11 is electrically connected with the circuit board 15, and the circuit board 15 is used to run the picture of the first display part 11. That is, the RGB lamp beads 141 and the first display part 11 share the same circuit board 15, improving the integration of the knob assembly 1 and facilitating compact structure.

[0075] In some embodiments, the circuit board 15 is used to cooperatively control the light-emitting color of the plurality of RGB lamp beads 141 and the picture of the first display part 11.

[0076] Exemplarily, please refer to Figure 2 , Figure 4 and Figure 5 , the support structure 13 includes an end cover 131 and a first support 132, and the end cover 131 is arranged at one side of the first support 132 along the axial direction of the knob operating part 10.

[0077] The end cover 131 serves as the appearance surface of the knob assembly 1.

[0078] Exemplarily, the first support 132 has a ring groove 132a, and the knob assembly 1 includes a light guide ring 17, at least a part of the light guide ring 17 is accommodated in the ring groove 132a, and the light guide ring 17 is used to guide the light of the light-emitting structure 14 to the end cover 131. It can be understood that after the light of the light-emitting structure 14 enters the light guide ring 17, the light is refracted and / or reflected in the light guide ring 17, so that the light emitted from the light guide ring 17 is more uniform, which is beneficial to making the light of the annular display part 12 more soft and uniform.

[0079] In this embodiment, in the embodiment in which the light-emitting structure 14 includes a plurality of lamp beads, the light guide ring 17 can convert the point light source emitted by the plurality of lamp beads into a surface light source, improving the uniformity of the light.

[0080] Exemplarily, please refer to Figure 4The sawtooth structure 17a can diversify the reflection angle of the light rays, reduce the concentration of the reflected light rays, and improve the uniformity of the light distribution.

[0081] For example, refer to Figure 2 The support structure 13 includes a second support 133, which is arranged on the second side of the first support 132 along the axial direction of the knob operation part 10, i.e., the side of the first support 132 away from the end cover 131. The circuit board 15 is clamped between the first support 132 and the second support 133 to improve the mounting stability of the circuit board 15.

[0082] For example, refer to Figure 2 The knob assembly 1 further includes a light-blocking film layer 23 arranged on the side of the end cover 131 close to the light guide ring 17. The light-blocking film layer 23 is used to block light, i.e., the light-blocking film layer 23 is not transparent to light. The end cover 131 can be made of a light-transmitting material as a whole. The uncovered part of the end cover 131 defines the annular light-emitting area and the first display part 11. In this way, the annular display part 12 and the first display part 11 presented on the end cover 131 have obvious boundaries in vision, which is beneficial to improving the visual enjoyment of the user.

[0083] It should be noted that the specific type of the light-blocking film layer 23 is not limited, for example, it can be a light-blocking film.

[0084] For example, refer to Figure 5 to Figure 7 The light-emitting structure 14 is located on the radial inner side or the radial outer side of the light guide ring 17, so that the light-emitting structure 14 is arranged radially offset from the annular light-emitting area. In this way, in the orthographic projection on the plane of the first display part 11, the light-emitting structure 14 and the annular light-emitting area do not overlap.

[0085] The position of the light-emitting structure 14 includes the following types: first, the light-emitting structure 14 is located on the radial inner side of the light guide ring 17. Second, the light-emitting structure 14 is located on the radial outer side of the light guide ring 17. Third, part of the light-emitting structure 14 is located on the radial outer side of the light guide ring 17, and the other part is located on the radial inner side of the light guide ring 17.

[0086] For example, refer to Figure 5 The first support 132 has a mounting groove 132b, and the ring groove 132a surrounds the outer periphery of the mounting groove 132b. The first display part 11 is arranged in the mounting groove 132b. In this embodiment, the mounting groove 132b is used to accommodate the first display part 11, which facilitates the positioning and mounting of the first display part 11.

[0087] For example, refer toFigure 2 、 Figure 5 and Figure 6 The knob assembly 1 further comprises a connecting piece 24 connected with the support structure 13, and the connecting piece 24 is used to mount the knob assembly 1 on a housing or other structure.

[0088] In the embodiment in which the support structure 13 comprises the second support 133, the connecting piece 24 is arranged on the side of the second support 133 away from the circuit board 15, and the connecting piece 24 is connected with the second support 133.

[0089] Exemplarily, one end of the connecting piece 24 is provided with a plurality of elastic hooks 241, and the connecting piece 24 is connected with the housing or other structure through the elastic hooks 241.

[0090] In some embodiments, the knob operation part 10 is used to input a scroll instruction by rotation, and the first display part 11 is used to scroll and display a function item corresponding to the scroll instruction in the case that the scroll instruction is input.

[0091] For the laundry treating apparatus, please refer to Figure 10 The function item can be a washing and treating main program, which can include, for example, intelligent washing, color protection washing, chemical fiber, bath towel, plush, wool, steam washing, etc. The icon is only used to distinguish different functions. The icon can be at least one of a text and a figure. The text can be Chinese, alphabets, etc.

[0092] After the knob operation part 10 rotates to input a scroll instruction, the function items of intelligent washing, color protection washing, chemical fiber, bath towel, plush, wool, steam washing, etc. are scrolled and displayed on the first display part 11. It should be noted that the function item displayed on the first display part 11 is the currently selected function item, and the program corresponding to the function item can be executed after the laundry treating apparatus is started.

[0093] For example, the knob operation part 10 rotates by a preset angle each time, and the first display part 11 switches to display the next function item from the current function item.

[0094] Exemplarily, please refer to Figure 1 、 Figure 9 、 Figure 10 The laundry treating apparatus further comprises a second display part 2, and the second display part 2 extends along a first direction. The second display part 2 is substantially in a strip shape.

[0095] The specific type of the second display part 2 is not limited, which can be, for example, an LCD screen (Liquid Crystal Display), an LED screen (Light Emitting Diode), etc.

[0096] For example, the knob assembly 1 is arranged at the front side of the laundry treating apparatus, and the first direction can be the left-right direction of the laundry treating apparatus. For another example, the knob assembly 1 is arranged at the left side or the right side of the laundry treating apparatus, and the first direction can be the front-rear direction of the laundry treating apparatus.

[0097] The knob assembly 1 and the second display part 2 are arranged adjacent to each other in the first direction. That is, the knob assembly 1 is arranged at one end of the second display part 2 in the first direction and adjacent to the second display part 2.

[0098] For example, the knob operating part 10 protrudes from the second display part 2 in the axial direction, that is, the first display part 11 and the second display part 2 are not in the same plane, and the first display part 11 protrudes from the second display part 2 in the axial direction.

[0099] The second display part 2 is configured to display a plurality of function items that can be selected. The specific content of the function items can be set according to the function of the laundry treating apparatus.

[0100] For example, in the case that the knob operating part 10 inputs a scroll instruction by rotation, the plurality of function items displayed on the second display part 2 move in the first direction and are displayed one by one on the first display part 11.

[0101] It should be noted that the plurality of function items on the second display part 2 can move continuously or jump in the first direction. For example, referring to Figure 10 , taking the function items of the above laundry treating apparatus as an example, assuming that the first interface can only display four function items, from the direction close to the knob assembly 1 to the direction away from the knob assembly 1, the four function items of color protection washing, mixing, wool, and color protection are displayed in turn, and the four function items move synchronously in the direction close to the knob assembly 1, when the color protection washing moves away from the second display part 2 and jumps to the first display part 11 for display, then the mixing moves away from the second display part 2 and jumps to the first display part 11 for display (at this time, the color protection washing will not be displayed on the first display part 11, that is, when the next function item jumps to the first display part 11 for display, the previous function item on the first display part 11 will be automatically covered), and so on.

[0102] It should be noted that when the color protection washing moves away from the second display part 2, the next function item can be displayed on the second display part 2.

[0103] In the above embodiment, the first display part 11 and the second display part 2 cooperatively display the function items, which can increase the dynamic effect.

[0104] It should be noted that the names of the functional items in the above embodiments of the present application are described taking a washing machine as an example. The laundry treatment apparatus of the embodiments of the present application can also be a drying machine or a washer-dryer.
