Description

Technical Field

[0001] This invention relates to the field of button technology, specifically to a button anti-light leakage device, an operation panel, and a washing machine. Background Technology

[0002] A button is a manually controlled electrical control device, mainly used to issue operating commands, connect or disconnect control circuits, and control the operation of mechanical and electrical equipment. With the development of society and changing needs, washing machines have become increasingly feature-rich. Some models use two or more physical buttons, each with its own light source. Pressing a button illuminates the corresponding light source.

[0003] Because of the limited space in a washing machine, the buttons are very close together. This means that when one button is lit, due to the nature of light propagation, the light source will also be visible in adjacent buttons, a phenomenon known as light leakage. Light leakage seriously affects the user experience. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a button light leakage prevention device, an operation panel, and a washing machine, thereby solving the problems of light leakage and cross-contamination at adjacent buttons when there are multiple buttons.

[0005] The first technical solution adopted by the present invention to solve the technical problem is a button anti-light leakage device, including a button body, a button is provided on the button body, the button is mounted on a button plate, and LED beads are provided on the button plate around the button. The button is provided with a first light-shielding member on its outer periphery, and the LED beads on the outer periphery of the button are surrounded within the first light-shielding member; The button body is provided with at least two buttons, and a second light-shielding member is provided between adjacent buttons to separate adjacent buttons. The outer end of the button is covered with a third light-shielding member, which is disposed between the button and the panel. Furthermore, the button body includes a box with an opening at one end, the opening of which is closed by a panel, and the panel has a plurality of button holes, each corresponding to a button.

[0006] Furthermore, the keypad is fixed inside the box, a button is installed on the outer end of the keypad, the button is sleeved in the button hole, the third light-shielding member is sleeved on the button, and the third light-shielding member is fixed on the inner side of the panel.

[0007] Furthermore, the button is mounted on a bracket, which is installed inside the box. The second light-shielding component includes an inner light-shielding partition and an outer light-shielding partition. The inner light-shielding partition is disposed on the side of the bracket facing the button panel, and the outer light-shielding partition is disposed on the side of the bracket away from the button panel.

[0008] Furthermore, the side of the bracket facing away from the button panel is covered with a transparent decorative sheet, and the side of the bracket facing the button panel is covered with a button film. The button film separates the button from the key. The transparent decorative sheet is provided with a sleeve portion, which is fitted onto the button. A third light-shielding member is fitted over the sleeve portion.

[0009] Furthermore, each button is individually fitted with a transparent decorative piece.

[0010] Furthermore, a transparent decorative sheet is provided, on which several sleeve portions are provided, with each sleeve portion corresponding to a button, and a clearance hole is provided between adjacent sleeve portions for the outer light-shielding partition to pass through.

[0011] Furthermore, the first light-shielding component includes an outer light-shielding ring and an inner light-shielding ring, with the outer light-shielding ring and the inner light-shielding ring forming an area for accommodating the lamp bead, and both the outer light-shielding ring and the inner light-shielding ring are mounted on a bracket.

[0012] The second technical solution adopted by the present invention to solve the technical problem is to provide an operation panel, including the above-mentioned button light leakage prevention device. The third technical solution adopted by the present invention to solve the technical problem is to provide a washing machine including the above-mentioned button anti-light leakage device.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The first light-shielding component can block the light emitted by the LED beads, preventing it from spreading in all directions and avoiding mutual interference between the light sources. The second light-shielding component separates adjacent buttons, which can reduce the light diffraction problem between adjacent buttons; The third light-shielding component is placed between the button and the panel to block light diffraction within the gap between the button and the panel. This device uses multiple physical barriers to block the light emitted by the LED beads layer by layer, continuously reducing the light propagation effect, thereby solving the problems of light leakage and crosstalk between buttons.

Detailed Implementation

[0020] Preferred embodiments of the invention are described in more detail below; however, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the invention.

[0021] Because of the limited space in a washing machine, the buttons are very close together. This means that when one button is lit, due to the nature of light propagation, the light source will also be visible in adjacent buttons, a phenomenon known as light leakage. Light leakage seriously affects the user experience.

[0022] Example 1: To address the aforementioned issues, Embodiment 1 provides a button light leakage prevention device to solve the problems of light leakage and cross-contamination at adjacent buttons in the case of multiple buttons.

[0023] like Figure 1-4 As shown, a button light leakage prevention device includes a button body, on which a button 72 is provided, the button 72 is mounted on a button plate 7, and LED beads 71 ​​are provided on the button plate 7 around the button 72. The button 72 is provided with a first light-shielding member 6 around its outer periphery, and the LED beads 71 ​​around the button 72 are surrounded by the first light-shielding member 6; the first light-shielding member 6 can block the light emitted by the LED beads 71 ​​to prevent it from spreading to the surroundings and to prevent the light sources from interfering with each other. The button body is provided with at least two buttons 72, and a second light-shielding member is provided between adjacent buttons 72; the second light-shielding member separates adjacent buttons, which is used to reduce the light diffraction problem between adjacent buttons 72, reduce the light diffraction problem in the gap between the button film 5 and the internal components of the box 4, and block the light diffraction problem at the decorative piece 2. The outer end of the button 72 is covered with a third light-shielding member 11, which is disposed between the button and the panel. The third light-shielding member 11 is used to block the light diffraction problem in the gap between the button 72 and the panel 1. In use, through the light-shielding effect of the first light-shielding member 6, the second light-shielding member, and the third light-shielding member 11, the light emitted by the LED bead 71 can only be focused on the top of the button 72 through diffraction. This device blocks the light emitted by the LED bead 71 layer by layer through multiple physical shielding, continuously weakening the light propagation effect, thereby solving the problem of light leakage and cross-contamination between the buttons 72.

[0024] In this embodiment, the button body includes a box 4 with one open end. The open end of the box 4 is closed by a panel 1. The box and the panel 1 are locked together by screws. To facilitate pressing operation, a plurality of button holes 12 are provided on the panel 1. The button holes 12 are arranged one-to-one with the buttons 72.

[0025] In this embodiment, the button plate 7 is fixed inside the box 4, the button 72 is equipped with a button 3 at its outer end, the button 3 is sleeved in the button hole 12, the third light-shielding member 11 is sleeved on the button 3, the third light-shielding member 11 is fixed on the inner side of the panel 1, the third light-shielding member 11 can be integrally formed with the panel 1 or snap-fit ​​connected, specifically, the third light-shielding member 11 is in the shape of a ring.

[0026] In this embodiment, the button 3 is mounted on the bracket 33. The button is connected to the bracket via an elastic wall. By pressing, the elastic wall deforms, allowing the button to be activated by pressing and moving. The bracket 33 is installed inside the housing 4 and is snapped to the panel 1. The second light-shielding component includes an inner light-shielding partition 32 and an outer light-shielding partition 31. The inner light-shielding partition 32 is disposed on the side of the bracket 33 facing the button plate 7, and the outer light-shielding partition 31 is disposed on the side of the bracket 33 away from the button plate 7.

[0027] In this embodiment, a transparent decorative sheet 2 is covered on the side of the bracket 33 facing away from the button plate 7, and a button film 5 is covered on the side of the bracket 33 facing the button plate 7. The button film 5 separates the button 3 from the button 72. To improve installation stability, a sleeve portion is provided on the transparent decorative sheet 2, and the sleeve portion is fitted onto the button 3. A third light-shielding member 11 is fitted outside the sleeve portion of the transparent decorative sheet 2 to provide light shielding for this part.

[0028] In this embodiment, the inner light-shielding partition 32 is located in the middle of the adjacent button 72. To ensure the light-shielding effect, both ends of it are located outside the first light-shielding member 6. The minimum distance between the inner light-shielding partition 32 and the button film 5 is 0mm-1.2mm, which has the best light-shielding effect. The inner light-shielding partition 32, as the second light-shielding barrier, reduces the light diffraction problem in the gap between the button film 5 and the internal components of the box 4.

[0029] In this embodiment, the outer light-shielding partition 31 is located in the middle of the adjacent button 3. To ensure the light-shielding effect, both ends of it are located outside the first light-shielding member 6. The distance between the outer light-shielding partition 31 and the panel 1 is 0mm-0.4mm for the best light-shielding effect. The distance between the third light-shielding member 11 and the decorative piece 2 is 0-0.4mm for the best light-shielding effect. Since the decorative piece 2 is a transparent piece, light can propagate inside it. The outer light-shielding partition 31, as the third light-shielding barrier, can further block the diffraction of light at the decorative piece 2. The outer light-shielding partition 31 and the third light-shielding member 11 work together as the fourth light-shielding barrier to block the light diffraction problem in the gap between the button 3 and the panel 1. Through the four barriers, the light leakage problem of the adjacent button 72 can be solved.

[0030] In practical applications, one assembly structure is to independently mount a transparent decorative piece 2 on each button 3.

[0031] In practical applications, another assembly structure is to set a transparent decorative piece 2 with several sleeve parts on it. The sleeve parts are set one-to-one with the button 3. Each adjacent sleeve part is provided with a clearance hole 21 for the outer light-shielding partition 31 to pass through.

[0032] In this embodiment, the first light-shielding member 6 includes an outer light-shielding ring 61 and an inner light-shielding ring 62. The outer light-shielding ring 61 and the inner light-shielding ring 62 form an area for accommodating the lamp bead 71. The outer light-shielding ring 61 and the inner light-shielding ring 62 are both mounted on the bracket 33. The lamp bead 71 is surrounded by the outer light-shielding ring 61 and the inner light-shielding ring 62. The outer light-shielding ring 61 and the inner light-shielding ring 62 serve as the first light-shielding barrier to prevent the light sources from interfering with each other. To ensure the light-shielding effect, the distance between the outer light-shielding ring 61, the inner light-shielding ring 62 and the control panel is less than the height of the light-emitting part of the lamp bead 71.

[0034] In this embodiment, the operation panel includes the button light leakage prevention device of embodiment 1.

[0035] Example 3: Example 3 provides a washing machine based on Example 1.
