[0007] A first display unit is located radially inside the knob operation unit, and the first display unit is used to display a screen.

[0008] A ring-shaped display portion surrounds the outer periphery of the first display portion and is located radially inside the knob operation portion. The ring-shaped display portion is used to guide the light emitted by the light-emitting structure to the external field of view of the knob assembly.

[0009] In some embodiments, the first display portion is circular, the annular display portion is ring-shaped, and the first display portion, the annular display portion, and the knob operation portion are concentrically arranged.

[0010] In some embodiments, the outer diameter of the first display part is 1 / 3 to 2 / 3 of the inner diameter of the knob operation part.

[0011] In some embodiments, the annular display includes a light-emitting structure and an annular light-emitting area surrounding the outer periphery of the first display, the annular light-emitting area being used to direct the light emitted by the light-emitting structure to the external field of view of the knob assembly.

[0012] In some implementations, in the orthographic projection of the plane containing the first display unit, the light-emitting structure and the annular light-emitting area do not overlap, and the support structure blocks the light-emitting structure.

[0013] In some embodiments, the knob assembly includes a circuit board, and the light-emitting structure includes a plurality of RGB LEDs disposed on the circuit board. The plurality of RGB LEDs are arranged circumferentially on the circuit board along the annular light-emitting area, and the circuit board is used to control the light emission color of the plurality of RGB LEDs.

[0014] In some implementations, the first display unit is electrically connected to the circuit board, which is used to run the image displayed on the first display unit.

[0015] In some embodiments, the support structure includes an end cap and a first support, the end cap being disposed on one side of the first support along the axial direction of the knob operating portion, the first support having an annular groove, the knob assembly including a light guide ring, at least a portion of the light guide ring being accommodated in the annular groove, the light guide ring being used to guide the light from the light-emitting structure to the end cap.

[0016] In some embodiments, the light-emitting structure is located radially inside or radially outside the light guide ring, so that the light-emitting structure is radially offset from the annular light-emitting area.

[0017] In some embodiments, the first bracket has a mounting groove, the annular groove surrounds the outer periphery of the mounting groove, and the first display portion is disposed in the mounting groove.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0042] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0043] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0044] This application provides a knob assembly. The application scenarios for the knob assembly are not limited. This application describes the knob assembly as being used in a garment processing device, but it is understood that the knob assembly can also be used in cooking equipment, refrigerators, and other household appliances.

[0045] This application provides a garment processing device, including a housing and a knob assembly 1 according to any embodiment of this application. The specific type of garment processing device is not limited, and may include, for example, a washing machine, a dryer, a washer-dryer combo, etc., and is not limited herein.

[0046] The knob assembly 1 is located on the housing and exposed on the outer surface of the housing. That is, the user can see the knob assembly 1.

[0047] Please refer to Figure 1 and Figure 2 The knob assembly 1 includes a support structure 13, a knob operation part 10, a first display part 11, and a ring-shaped display part 12.

[0048] Please refer to Figure 1 and Figure 2 The knob operating part 10 surrounds the outer periphery of the bracket structure 13 and is rotatable relative to the bracket structure 13. It is understood that the knob operating part 10 can rotate relative to the outer casing. For example, the knob operating part 10 rotates under the user's turning operation; furthermore, during the rotation of the knob operating part 10, the bracket structure 13, the first display part 11, and the annular display part 12 do not rotate with the knob operating part 10.

[0049] For example, the knob operation unit 10 can be used to select programs or adjust parameters during rotation.

[0050] Please see Figure 10 The first display unit 11 is used to display the screen.

[0051] Please refer to Figure 1 and Figure 2 The first display section 11 is located radially inside the knob operation section 10, that is, the knob operation section 10 surrounds the outer periphery of the first display section 11.

[0052] Please refer to Figure 1 The annular display portion 12 surrounds the outer periphery of the first display portion 11 and is located radially inside the knob operation portion 10. The annular display portion 12 is used to guide light to the external field of view of the knob assembly 1. That is, in the radial direction of the knob operation portion 10, the annular display portion 12 is located between the knob operation portion 10 and the first display portion 11.

[0053] The ring-shaped display section 12 refers to the area used to display a ring of bright light. In other words, the user can see the ring-shaped display section 12.

[0054] In this embodiment of the rotary assembly, since the annular display portion 12 is located between the first display portion 11 and the rotary operation portion 10, please refer to... Figure 10When the first display unit 11 displays a screen, the light from the ring display unit 12 can provide a visual transition between the first display unit 11 and the knob operation unit 10, which also helps to improve the layout rationality of the knob assembly 1.

[0055] For example, please refer to Figure 1 The annular display section 12 and the knob operation section 10 are arranged radially spaced apart on the knob operation section 10. Please refer to the attached document. Figure 10 The area between the ring-shaped display section 12 and the knob operation section 10 is a non-display area.

[0056] For example, please refer to Figure 1 The annular display section 12 and the first display section 11 are arranged radially apart on the knob operation section 10, and the interval area between the annular display section 12 and the first display section 11 is a non-display area.

[0057] For example, when the knob assembly is in the off or standby state, the non-display area and the first display section 11 are displayed in approximately the same color, for example, both are black. This improves the consistency of appearance when the device is off or in standby state.

[0058] It should be noted that the above-mentioned radial positional relationship of the annular display section 12, the knob operation section 10, and the first display section 11 is the appearance projection of the plane where the first display section 11 is located, and can also be understood as the positional relationship of the three as observed from the appearance of the user's external knob assembly.

[0059] The specific outline shape of the first display unit 11 is not limited; for example, it can be elliptical, polygonal, etc.

[0060] For example, please refer to Figure 1 and Figure 10 The first display section 11 is circular, and the annular display section 12 is ring-shaped. The first display section 11, the annular display section 12, and the knob operation section 10 are concentrically arranged. This results in a more reasonable overall layout and better aesthetic consistency. It should be noted that the shapes described above refer to the shapes projected onto a plane perpendicular to the rotation axis of the knob operation section 10.

[0061] It should be noted that the knob operating part 10 has an appropriate extension length along 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 designed for user gripping.

[0062] For example, please refer to Figure 1When the first display part 11 is circular, its outer diameter D1 is 1 / 3 to 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 between the first display part 11 and the knob operation part 10 is relatively moderate and reasonable. With the knob operation part 10 being sized to be easy for the user to hold, the first display part 11 has a suitable area to display the image.

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

[0064] For example, the annular display unit 12 includes a light-emitting structure 14 and an annular light-emitting area. The annular light-emitting area surrounds the outer periphery of the first display unit 11 and is used to guide the light emitted by the light-emitting structure 14 to the external field of view of the knob assembly 1. The light-emitting structure 14 serves as a light source to generate the desired light. The annular light-emitting area refers to the position where the light from the light-emitting structure 14 leaves the light-emitting position of the knob assembly 1.

[0065] It should be noted that, in the external projection of the plane where the first display section 11 is located, the external outline of the annular display section 12 is the same as the external outline of the annular light-emitting area.

[0066] In related technologies, multiple LEDs are arranged inside the light-emitting position of the ring-shaped display section. The area between two adjacent LEDs has lower brightness, while the LEDs themselves have higher brightness. Users can observe the graininess of the LEDs, which affects the appearance.

[0067] Therefore, in some embodiments of this application, in the orthographic projection of the plane where the first display unit 11 is located, the light-emitting structure 14 and the annular light-emitting area do not overlap, and the bracket structure 13 blocks the light-emitting structure 14. In this way, the light-emitting structure 14 is blocked by the bracket structure 13, and the light-emitting structure 14 cannot be observed from the external surface of the knob assembly 1, which helps to improve the particle appearance of the LED beads in the related art.

[0068] In some embodiments, please refer to Figure 2 and Figure 3 The knob assembly 1 includes a circuit board 15, and the light-emitting structure 14 includes multiple RGB LED beads 141 disposed on the circuit board 15. The multiple RGB LED beads 141 are arranged circumferentially on the circuit board 15 along the annular light-emitting area. The circuit board 15 is used to control the light emission color of the multiple RGB LED beads 141. The working principle of the RGB LED beads 141 is to change the brightness by controlling the current of the red, green, and blue LED beads, and thus achieve a color effect through the combination of different colors.

[0069] In this embodiment, the RGB LED beads 141 are driven and controlled by the circuit board 15, which can diversify the appearance colors of the ring-shaped display section 11.

[0070] It should be noted that there is no limit to the specific number of RGB LEDs (141).

[0071] The specific form of the circuit board 15 is not limited. For example, the circuit board 15 is generally circular, which facilitates its assembly into the knob operation part 10.

[0072] The specific type of the first display unit 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 unit 11 may have a portion that is a touch-sensitive screen, and the remaining portion that constitutes a non-touch-sensitive screen. Alternatively, the first display unit 11 may be entirely a touch-sensitive screen. A touch-sensitive screen may also be referred to as a sensor screen or a touchscreen.

[0074] For example, the first display unit 11 is electrically connected to the circuit board 15, which is used to display the screen of the first display unit 11. That is, the RGB LED 141 and the first display unit 11 share the same circuit board 15, which improves the integration of the knob assembly 1 and makes the structure more compact.

[0075] In some embodiments, the circuit board 15 is used to coordinate the emission colors of multiple RGB LED beads 141 and the image displayed on the first display unit 11.

[0076] For example, please refer to Figure 2 , Figure 4 and Figure 5 The bracket structure 13 includes an end cap 131 and a first bracket 132. The end cap 131 is disposed on one side of the first bracket 132 along the axial direction of the knob operation part 10.

[0077] End cap 131 serves as the exterior surface of knob assembly 1.

[0078] Exemplarily, the first bracket 132 has an annular groove 132a, and the knob assembly 1 includes a light guide ring 17, at least a portion of which is accommodated in the annular groove 132a. The light guide ring 17 is used to guide the light from the light-emitting structure 14 to the end cap 131. It is understood that after the light from the light-emitting structure 14 enters the light guide ring 17, the light is refracted and / or reflected within the light guide ring 17, making the light emitted from the light guide ring 17 more uniform, which is beneficial for making the light from the annular display section 12 softer and more uniform.

[0079] In this embodiment, where the light-emitting structure 14 includes multiple LEDs, the light guide ring 17 can convert the point light source emitted by the multiple LEDs into a surface light source, thereby improving the uniformity of the light.

[0080] For example, please refer to Figure 4The light guide ring 17 has a serrated structure 17a on the side near the light-emitting structure 14. After the light emitted by the light-emitting structure 14 enters the light guide ring 17, the serrated structure 17a can diversify the reflection angle of the light, reduce the concentration of the reflected light, and improve the uniformity of the light distribution.

[0081] For example, please refer to Figure 2 The bracket structure 13 includes a second bracket 133, which is disposed on the second side of the first bracket 132 along the axial direction of the knob operation part 10, that is, on the side of the first bracket 132 away from the end cover 131. The circuit board 15 is sandwiched between the first bracket 132 and the second bracket 133 to improve the installation stability of the circuit board 15.

[0082] For example, please refer to Figure 2 The knob assembly 1 also includes a light-shielding film layer 23, which is disposed on the side of the end cover 131 near the light guide ring 17. The light-shielding film layer 23 is used to block light, that is, the light-shielding film layer 23 is opaque. The end cover 131 can be made entirely of a light-transmitting material, and the area of ​​the end cover 131 not covered by the light-shielding film layer 23 defines an annular light-emitting area and a first display part 11. In this way, through the blocking of the light-shielding film layer 23, the annular display part 12 and the first display part 11 presented on the end cover 131 have a clear visual boundary, which helps to improve the user's visual viewing experience.

[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, please refer to Figures 5 to 7 The light-emitting structure 14 is located radially inside or radially outside the light guide ring 17, so that the light-emitting structure 14 and the annular light-emitting area are arranged radially offset. In this way, in the orthographic projection of the plane where the first display section 11 is located, the light-emitting structure 14 and the annular light-emitting area do not overlap.

[0085] The positions of the light-emitting structure 14 can be one of the following: First, the light-emitting structure 14 is located radially inside the light guide ring 17. Second, the light-emitting structure 14 is located radially outside the light guide ring 17. Third, a portion of the light-emitting structure 14 is located radially outside the light guide ring 17, and another portion is located radially inside the light guide ring 17.

[0086] For example, please refer to Figure 5 The first bracket 132 has a mounting groove 132b, and an annular groove 132a surrounds the outer periphery of the mounting groove 132b. The first display part 11 is disposed in the mounting groove 132b. In this embodiment, the first display part 11 is accommodated by the mounting groove 132b, which facilitates the positioning and installation of the first display part 11.

[0087] For example, please refer to Figure 2 , Figure 5 and Figure 6 The knob assembly 1 also includes a connector 24, which is connected to the bracket structure 13 and is used to mount the knob assembly 1 onto the housing or other structure.

[0088] In an embodiment where the support structure 13 includes a second support 133, a connector 24 is disposed on the side of the second support 133 away from the circuit board 15, and the connector 24 is connected to the second support 133.

[0089] For example, one end of the connector 24 has a plurality of resilient hooks 241, which are used to connect to the housing or other structures.

[0090] In some embodiments, the knob operation unit 10 is used to input a scroll command by rotating it, and the first display unit 11 is used to scroll and display the function item corresponding to the scroll command when the scroll command is input.

[0091] For garment processing equipment, please refer to Figure 10 The functional items can be the main washing and care program, such as: smart wash, color protection wash, synthetic fiber wash, bath towel wash, plush wash, wool wash, steam wash, etc. The icons are only for distinguishing different functions. Icons can be at least one of text or graphics. Text can be Chinese characters, letters, etc.

[0092] After the rotary knob 10 is rotated to input the scrolling command, functions such as smart wash, color protection wash, synthetic fiber, bath towel, plush, wool, and steam wash will be scrolled on the first display 11. It should be noted that the function displayed on the first display 11 is the currently selected function. When the garment processing equipment is started, the program corresponding to that function can be executed.

[0093] For example, every time the knob operation unit 10 is rotated by a preset angle, the first display unit 11 switches from displaying the current function item to displaying the next function item.

[0094] For example, please refer to Figure 1 , Figure 9 , Figure 10 The garment processing equipment also includes a second display unit 2, which extends along the first direction. The second display unit 2 is generally elongated.

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

[0096] For example, if the knob assembly 1 is located on the front of the garment processing device, the first direction can be the left-right direction of the garment processing device. Or, for example, if the knob assembly 1 is located on the left or right side of the garment processing device, the first direction can be the front-back direction of the garment processing device.

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

[0098] For example, the knob operation part 10 protrudes axially from the second display part 2, that is, the first display part 11 and the second display part 2 are not on the same plane, and the first display part 11 protrudes axially from the second display part 2.

[0099] The second display unit 2 is used to display multiple selectable function items. The specific content of the function items can be set according to the functions of the garment processing equipment.

[0100] For example, when the knob operation unit 10 inputs a scroll command by rotating, multiple function items displayed on the second display unit 2 move in the first direction and jump to the first display unit 11 one by one for display.

[0101] It should be noted that the movement of multiple function items on the second display unit 2 in the first direction can be continuous or intermittent. For example, please refer to... Figure 10 Taking the above-mentioned garment processing equipment as an example, if the first interface can only display four functional items, the four functional items of color protection wash, blending, wool, and anti-color bleeding are displayed sequentially from the direction closer to the knob assembly 1 to the direction farther away from the knob assembly 1. The four functional items move synchronously towards the direction closer to the knob assembly 1. When color protection wash leaves the second display section 2 and jumps to the first display section 11 for display, then blending leaves the second display section 2 and jumps to the first display section 11 for display (at this time, color protection wash will not be displayed on the first display section 11, that is, when the next functional item jumps to the first display section 11 for display, it will automatically cover the previous functional item on the first display section 11), and so on.

[0102] It should be noted that when the color protection wash leaves the second display unit 2, the next function item can be added and displayed on the second display unit 2.

[0103] In the above embodiments, the first display unit 11 and the second display unit 2 cooperate to display functional items, which can increase the dynamic effect.

[0104] 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.

[0105] For example, please refer to Figure 1 The dimension H1 of the first display unit 11 in the second direction is 4 / 5 to 1 of the dimension H2 of the second display unit 2 in the second direction, i.e., H2*4 / 5 ≤ H1 ≤ H2. For example, when the first display unit 11 is circular, H1 is the outer diameter of the first display unit 11, and the second display unit 2 is approximately rectangular, the outer diameter of the first display unit 11 is 4 / 5 to 1 of the shorter side of the second display unit 2. The first and second directions are perpendicular. Thus, the dimensions of the first display unit 11 and the second display unit 2 in the second direction are relatively close, and the dimension of the first display unit 11 in the second direction is not greater than the dimension of the second display unit 2 in the second direction, resulting in a more harmonious proportion.

[0106] For example, the size of the knob operating portion 10 in the second direction is larger than the size of the second display portion 2 in the second direction. For instance, when the first display portion 11 is circular and the second display portion 2 is approximately rectangular, the outer diameter of the knob operating portion 10 is larger than the short side of the second display portion 2. The outer diameter of the knob operating portion 10 can be relatively large for easy gripping by the user, while the size of the second display portion 2 in the second direction does not exceed the outer diameter of the knob operating portion 10, resulting in a reasonable layout.

[0107] For example, please refer to Figure 1 , Figure 9 , Figure 10 The garment handling device also includes a third display unit 3 arranged adjacent to the knob assembly 1. The second display unit 2, the knob assembly 1, and the third display unit 3 are arranged sequentially along a first direction. That is, the knob assembly 1 is located between the second display unit 2 and the third display unit 3. The second display unit 2 and the third display unit 3 are structurally independent areas.

[0108] For example, the outline defined by the second display unit 2 and the third display unit 3 is a long rectangle. It is understood that the two long sides of the long rectangle are not continuous straight lines, but are broken at the knob assembly 1.

[0109] For example, please refer to Figure 9 , Figure 10The third display unit 3 is equipped with a power switch operation area 3A and / or a start / stop button operation area 3B. In other words, the power switch and start / stop button are located on the third display unit 3. Taking the power switch as an example, it controls whether the garment processing equipment is turned on or off. Taking the start / stop button as an example, it controls whether the garment processing equipment pauses or starts executing a selected program. After powering on, the third display unit 3 lights up, and the power switch icon and start / stop button icon are prominently displayed on the third display unit 3 for easy viewing and operation by the user.
