Description

Technical Field

[0001] This application relates to the field of washing machines, and more particularly to a button structure for a washing machine. Background Technology

[0002] The button structure for washing machines mainly involves the control panel of the washing machine, and these buttons are typically used to control various functions of the washing machine.

[0003] Currently, button installation typically involves creating several cavities on the panel and fixing the button to the inner wall of the cavity using two spring contacts. All of these are integrated structures, making it inconvenient to replace the button or spring contacts when they are damaged, which increases replacement costs. Utility Model Content

[0004] To address the issue of inconvenience in replacing buttons and springs when the button, spring, and panel are integrated into one unit, this application provides a button structure for a washing machine.

[0005] The button structure for a washing machine provided in this application adopts the following technical solution:

[0006] A button structure for a washing machine includes several cavities formed on the top of the panel. Each of the cavities is equipped with a button assembly. The button assembly includes a sleeve disposed in the cavity. A pair of spring contacts are fixedly connected to the bottom of the sleeve. A conical block is fixedly connected to the bottom of each pair of spring contacts. A ring with a conical top is fixedly connected to the inner wall of the cavity. When the conical block slides down the inner wall of the cavity to the ring, it tends to converge toward the center under the action of the spring contacts. A pair of conical grooves are provided at the bottom of the ring.

[0007] A positioning block is fixed to the surface of the sleeve. The top of the panel is provided with a positioning groove and a through groove that are adapted to the shape of the positioning block. The positioning groove and the through groove are connected to the cavity. The inner wall of the cavity is provided with a rotating groove that is connected to the positioning groove and the through groove and allows the positioning block to rotate 90° clockwise. After the positioning block is inserted from the positioning groove into the rotating groove and rotated 90° clockwise, it corresponds to the through groove.

[0008] By adopting the above technical solution, the sleeve is inserted into the cavity. When the conical block slides down the inner wall of the cavity with the sleeve to the ring, the ring exerts an inward squeezing force on the conical block. This squeezing force causes the conical block to be subjected to a force that converges towards the center. As a result, the spring plate undergoes elastic deformation, causing the conical block to converge towards the center. Thus, the sleeve can be smoothly installed in the cavity. When the conical block slides down to the bottom of the ring, the squeezing force exerted by the ring on the conical block disappears. The spring plate causes the conical block to spring back to its original state, and the ring acts as a limiter for the conical block, restricting its upward movement. Thus, the sleeve is fixed in the cavity, making installation convenient and quick.

[0009] The installation of the sleeve is aided by setting a positioning block and a positioning groove.

[0010] Preferably, the conical block corresponds exactly to the conical groove when rotated 90° clockwise.

[0011] By adopting the above technical solution, the conical block can only rotate 90° clockwise with the cooperation of the positioning block and the rotating groove, which can just correspond to the conical groove.

[0012] Preferably, the arc length of the conical groove is equal to the arc length of the conical block.

[0013] By adopting the above technical solution, the arc length of the sector of the conical block is equal to the arc length of the sector of the conical groove. When the sleeve needs to be disassembled, when the sleeve is pulled upward, the conical surface of the conical groove abuts against the surface of the conical block, which will generate an inward squeezing force on the conical block. This squeezing force will cause the conical block to be subjected to a force that converges towards the center. Then, when the spring undergoes elastic deformation, it will drive the conical block to converge towards the center, and the sleeve can be pulled out from the cavity, making disassembly convenient and quick.

[0014] Preferably, when the pair of conical blocks are relaxed, they are distributed in a conical structure and the diameter of the top of the cone is equal to the inner diameter of the cavity.

[0015] By adopting the above technical solution, when the sleeve is installed in the cavity, the conical block is in a relaxed state and distributed in a conical structure. The top diameter of the conical block is equal to the inner diameter of the cavity, and the top edge of the conical block abuts against the inner wall of the cavity, avoiding the generation of play, so that the conical block cannot wobble and improving the overall stability.

[0016] Preferably, when the conical block slides down to the bottom and abuts against the bottom of the cavity, its top abuts against the bottom of the ring.

[0017] By adopting the above technical solution, the top and bottom of the conical block abut against the bottom of the ring and the bottom of the cavity, respectively, to avoid misalignment and further prevent the sleeve from sliding up and down in the cavity.

[0018] Preferably, the inner diameter of the ring is equal to the outer diameter of the sleeve.

[0019] By adopting the above technical solution, when the sleeve is installed in the cavity, the outer surface of the spring contact with the inner surface of the ring circumference, avoiding misalignment and preventing the sleeve from shaking in the cavity, thus further improving the stability of the device.

[0020] Preferably, the button body is fixed to the top of the inner wall of the sleeve by a pair of spring contacts.

[0021] By adopting the above technical solution, a pair of spring contacts are used to automatically reset the button body after the pressing force is removed.

[0022] Preferably, the bottom of the button body extends through the side wall of the panel and outwards.

[0023] By adopting the above technical solution, the force applied to the button body is transmitted to the mechanical button, thereby triggering the mechanical button to light up and activate it.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The button is installed inside the sleeve via a spring contact. The sleeve is detachably installed within the cavity. During installation, simply insert the sleeve into the cavity. The sleeve is limited by the cooperation of the conical block and the ring, restricting its sliding within the cavity, thus completing the button installation. Installation is convenient and quick. During disassembly, rotate the sleeve 90° clockwise. The pair of conical blocks will then align with the pair of conical grooves, allowing the conical blocks to be pulled out. This allows the sleeve to be pulled out of the cavity, completing the disassembly. The operation is simple and quick. When the button is damaged and needs replacement, it can be quickly replaced, thereby reducing costs. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] This application discloses a button structure for a washing machine.

[0037] Reference Figures 1-3 A button structure for a washing machine includes several cavities 2 formed at the top of a panel 1. A button assembly 3 is detachably installed in the cavity 2. The button assembly 3 includes a sleeve 31 disposed in the cavity 2. A pair of spring contacts 32 are stacked and fixedly connected to the top of the inner wall of the sleeve 31. A button body 34 is fixedly connected to the end of the spring contacts 32 away from the sleeve 31. The bottom of the button body 34 movably penetrates the side wall of the panel 1 and abuts against the top of the mechanical button. A pair of spring contacts 35 are symmetrically fixedly installed at the bottom of the sleeve 31. The pair of spring contacts 35 are distributed with a diameter equal to that of the sleeve 31. The cylinder 31 has a cylindrical structure with an equal outer diameter. A pair of conical blocks 36 are fixedly connected to the bottom of the corresponding spring piece 35. The pair of conical blocks 36 are distributed in a conical structure with a top diameter greater than the bottom diameter. The surface of the ring 4 is fixedly connected to the surface of the inner cavity of the cavity 2. The top of the ring 4 is set as a conical surface that matches the shape of the pair of conical blocks 36. The distance between the bottom of the ring 4 and the bottom of the inner cavity of the cavity 2 is equal to the height of the conical blocks 36. When the bottom of the conical blocks 36 abuts against the bottom of the inner cavity of the cavity 2, the outer circumferential surface of the spring piece 35 abuts against the inner circumferential surface of the ring 4.

[0038] The positioning block 33 is fixedly installed on the surface of the sleeve 31. The positioning groove 37 and the through groove 39, which communicate with the cavity 2, are both located on the top of the panel 1. The positioning block 33 is located within the positioning groove 37 and slides longitudinally. The outer circumferential surface of the positioning block 33 abuts against the inner circumferential wall of the positioning groove 37. A rotating groove 38, which communicates with the positioning groove 37 and the through groove 39, is located on the inner wall of the cavity 2. After passing through the positioning groove 37, the positioning block 33 is located within the rotating groove 38. Side A abuts against side A of the inner cavity of the rotating groove 38. The circumferential surface of the positioning block 33 abuts against the inner circumferential wall of the rotating groove 38. The top and bottom of the positioning block 33 abut against the top and bottom of the inner cavity of the rotating groove 38. When the positioning block 33 rotates 90° clockwise, side B of the positioning block 33 abuts against side B of the inner cavity of the rotating groove 38. The through groove 39 and the positioning groove 37 are adapted to the shape of the positioning block 33, and the side of the through groove 39 closest to side B of the rotating groove 38 is flush with side B of the inner cavity of the rotating groove 38.

[0039] The sleeve 31 is inserted into the cavity 2, and the positioning block 33 is aligned with the positioning groove 37 so that the positioning block 33 can be inserted into the positioning groove 37. When the sleeve 31, driven by the spring piece 35, slides the conical block 36 down to the ring 4, the ring 4 exerts an inward squeezing force on the pair of conical blocks 36. This squeezing force causes the conical blocks 36 to be subjected to a force that converges towards the center. Consequently, the spring piece 35 undergoes elastic deformation, causing the conical blocks 36 to converge towards the center. Sleeve 31 can be smoothly installed in cavity 2. When conical block 36 slides down to the bottom of ring 4, the squeezing force of ring 4 on conical block 36 disappears. Spring piece 35 drives conical block 36 to spring back to its original state. At this time, the top of conical block 36 abuts against the bottom of ring 4, and the bottom of conical block 36 abuts against the bottom of cavity 2. This limits conical block 36 between the bottom of ring 4 and the bottom of cavity 2, preventing it from sliding up and down, and thus preventing sleeve 31 from sliding up and down.

[0040] Meanwhile, the positioning block 33 is located inside the positioning groove 37, and the surface of the positioning block 33 abuts against the inner wall of the positioning groove 37, which prevents the sleeve 31 from shaking in the cavity 2, improves the stability of the device, and makes installation convenient and quick.

[0041] Reference Figures 3-6 A pair of conical grooves 5, whose fan-shaped arc length is equal to that of the conical block 36, are opened at the bottom of the ring 4, and the pair of conical blocks 36 are located at the position of the pair of conical grooves 5 after being rotated 90° clockwise.

[0042] When it is necessary to disassemble and replace the button body 34, the sleeve 31 needs to be removed from the cavity 2. With the cooperation of the positioning block 33 and the rotating groove 38, the sleeve 31 can only rotate 90° clockwise in the cavity 2. When the sleeve 31 rotates 90° clockwise, a pair of conical blocks 36 just rotate to the position of a pair of conical grooves 5. Then, pull the sleeve 31 upward. The conical surface of the conical groove 5 abuts against the surface of the conical block 36, which will generate an inward squeezing force on the conical block 36. This squeezing force will cause the conical block 36 to be subjected to a force that converges towards the center. As a result, the spring piece 35 undergoes elastic deformation, which drives the conical block 36 to converge towards the center. Then, the sleeve 31 can be pulled out from the cavity 2, making disassembly convenient and quick.

[0043] The implementation principle of a button structure for a washing machine according to an embodiment of this application is as follows: When installing the button, the sleeve 31 is inserted into the cavity 2, and the positioning block 33 is aligned with the positioning groove 37 so that the positioning block 33 can be inserted into the positioning groove 37. When the conical block 36 slides down to the ring 4, the ring 4 will exert an inward squeezing force on the pair of conical blocks 36, and then the spring piece 35 will undergo elastic deformation to drive the conical blocks 36 to converge towards the center, so that the sleeve 31 can be smoothly installed in the cavity 2. When the conical block 36 slides down to the bottom of the ring 4, the squeezing force of the ring 4 on the conical block 36 disappears, and the spring piece 35 drives the conical block 36 to spring back to the original state. At this time, the top of the conical block 36 abuts against the bottom of the ring 4, and the bottom of the conical block 36 abuts against the bottom of the inner cavity of the cavity 2, thereby limiting the conical block 36 between the bottom of the ring 4 and the bottom of the inner cavity of the cavity 2, preventing it from sliding up and down, and thus preventing the sleeve 31 from sliding up and down, thus completing the installation of the button.

[0044] When the button needs to be removed, with the cooperation of the positioning block 33 and the rotating groove 38, the sleeve 31 is rotated 90° clockwise. When the sleeve 31 is rotated 90° clockwise, the pair of conical blocks 36 are rotated to the position of the pair of conical grooves 5. Then, the sleeve 31 is pulled upward. The conical surface of the conical groove 5 abuts against the surface of the conical block 36, which will exert an inward squeezing force on the conical block 36. This squeezing force will cause the conical block 36 to be subjected to a force that converges towards the center. As a result, the spring piece 35 undergoes elastic deformation, which drives the conical block 36 to converge towards the center. Then, the sleeve 31 can be pulled out from the cavity 2, making disassembly convenient and quick.

[0045] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
