[0035] The following will elaborate on the specific implementation manners of the present invention in conjunction with the drawings of the specification. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Referring to Figures 1 - 3 , the key module 200 in an embodiment of the present invention is installed on the cabinet 100 of the washing machine, and the key module 200 is installed and arranged on the front end face of the cabinet 100. As Figure 7 and Figure 8As shown, the button module 200 includes a button bracket 210, a button board 220, and a circuit board 230. The button bracket 210 is embedded in the installation card slot of the box body 100. Touch buttons are provided on the circuit board 230, and the circuit board 230 is arranged on the inner side surface of the button bracket 210. The button board 220 is arranged on the outer side surface of the button bracket 210. Among them, the inside of the box body 100 is defined as the inner side direction, and the outside is defined as the outer side direction. A first clamping structure is provided between the button bracket 210 and the box body 100, and the button bracket 210 is clamped on the box body 100 through the first clamping structure. In order to further prevent the button module 200 from falling off during vibration or transportation, as Figures 3 - 5 shown, the button module 200 further includes a support cover 300. The support cover 300 is buckled outside the button bracket 210 and abuts against the inner side surface of the box body 100. A second clamping structure is provided between the support cover 300 and the button bracket 210, and the button bracket 210 is clamped on the box body 100 through the support cover 300 and the second clamping structure. Through the supporting effect of the support cover 300, the button bracket 210 is tightened, and together with the first clamping structure, a double insurance is formed to prevent the button module 200 from falling out of the installation card slot.

[0037] The above-mentioned button module 200 has a simple structure. Through the cooperation of the first clamping structure, the support cover 300 and the second clamping structure, double clamping fixation of the button bracket 210 is achieved, which can effectively prevent the button module 200 from falling out of the installation card slot during vibration or transportation; and the clamping structure is easy to assemble and operate.

[0038] Specifically, as Figure 6 、 Figure 9 and Figure 10As shown, a mounting slot is provided on the box 100. The first clamping structure includes a plug-in portion 212, a first clamping buckle 213 provided on the plug-in portion 212, and a slot flange 110 bent inwardly along the mounting slot. The button bracket 210 is embedded in the mounting slot, and the plug-in portion 212 is inserted into the mounting slot, and the first clamping buckle 213 is engaged with the slot flange 110. A groove 211 is provided around the button bracket 210, and the outer side of the groove 211 is higher than the inner side of the groove 211. Therefore, when the button bracket 210 is installed and embedded in the mounting slot of the box 100 from the outside, the outer side of the groove 211 abuts against the box 100 to ensure that the button module 200 will not fall out from the inside. Then, the outer side of the first clamping buckle 213 abuts against the slot flange 110 to fix the button bracket 210. In this embodiment, the shape of the key board 220 is preferably a rounded rectangle, and the plug-in portion 212 is arranged perpendicular to the front side of the key bracket 210. There are two plug-in portions 212, which are arranged on the upper and lower sides respectively. The upper and lower plug-in portions 212 are arranged staggered along the left and right directions, which can improve the clamping firmness of the plug-in portions 212. In other embodiments, the plug-in portions 212 can be arranged on the left and right sides or all around.

[0039] Specifically, Figure 6 As shown, the second snap-fit ​​structure includes a second snap 214 arranged on the plug-in portion 212, and the second snap 214 is arranged on the inner side of the first snap 213, that is, arranged at an end away from the front end surface of the box body 100. The support cover 300 is provided with an abutment portion 311 that cooperates with the second snap 214, and the second snap 214 abuts against the outer side of the abutment portion 311. The key bracket 210 is tightened by the support of the support cover 300, and together with the first snap-fit ​​structure, it constitutes a double insurance to prevent the key module 200 from falling off from the installation slot. The support cover 300 is an injection-molded integrated structure, and an extension portion 310 extending to the rear side is arranged on the support cover 300 along its side, and the abutment portion 311 is arranged on the extension portion 310. An opening is provided on the bottom surface of the support cover 300 at a position corresponding to the extension portion 310 for inserting the plug-in portion 212 of the key bracket 210 so that the second buckle 214 of the plug-in portion 212 is fixedly engaged with the abutment portion 311 of the extension portion 310. Both the first buckle 213 and the second buckle 214 are inverted buckle structures, so that the key module 200 is not easy to fall out.

[0040] Specifically, Figure 6 An opening is provided on the rear side of the support cover 300, and two upper and lower openings are provided on the rear side of the support cover. An extension portion 310 is provided on the upper side of the upper opening and the lower side of the lower opening, and the abutment portion 311 is provided on the extension portion 310. The plug-in portion 212 of the button bracket 210 extends out of the opening of the support cover 300, and the second buckle 214 is fixedly engaged with the abutment portion 311.

[0041] Further, a support post 320 is provided inside the support cover 300. As Figure 5 shown, the support post 320 abuts against the circuit board 230, pressing the circuit board 230 against the key bracket 210, which can prevent the circuit board 230 from loosening and falling off. In this embodiment, two support posts 320 are provided, which respectively abut against both sides of the circuit board 230.

[0042] As Figure 8 shown, a laser engraving texture 215 is provided on the outer side surface of the key bracket 210 opposite to the touch key. A vacuum plating layer is provided on the laser engraving texture 215. Through the vacuum plating technology, under vacuum conditions, the metal material is organically converted by specific means such as chemistry and physics, so that the metal is converted into particles, deposited or adsorbed on the surface of the key bracket 210, and combined with the laser engraving texture 215 to form a laser engraving texture 215 with a metallic texture. The key plate 220 is made of a transparent material, and the key plate 220 covers the outer side surface of the key bracket 210.

[0043] For the above-mentioned key module 200, the laser engraving texture 215 is provided on the outer side surface of the key bracket 210, and then a laser engraving texture 215 with a metallic texture is formed through vacuum plating. The transparent key plate 220 covers the laser engraving texture 215, which can not only ensure the aesthetic appearance of the metallic texture of the key, but also ensure that the user cannot directly touch the laser engraving texture 215, avoiding the cold feeling of touch and preventing dust from penetrating into the texture, thus improving the user experience.

[0044] Specifically, the key plate 220 includes a pattern part coated with patterns and a blank part. Various textures, patterns, logos, etc. can be coated on the pattern part. The blank part is opposite to the laser engraving texture 215, and the blank part is transparent, so that the laser engraving texture 215 can be prevented from being blocked.

[0045] The key plate 220 is adhesively fixed to the key bracket 210. Preferably, it is adhesively fixed between the key plate 220 and the key bracket 210 by 3M glue.

[0046] The peripheral side surfaces around the front end of the key module 200 are inclined surfaces 216 that gradually expand outward. By setting the peripheral side surfaces around the front end of the key module 200 as inclined surfaces 216 that gradually expand outward, an inclined gap that gradually expands from the inside to the outside is formed between the key module 200 and the installation slot, which is beneficial to reducing the gap between the two; and the gap between the key module 200 and the installation slot is blocked by the key module 200, and the gap is not easily seen from the front, increasing the overall aesthetic effect.

[0047] The area of the front end surface of the key module 200 is larger than the area of the installation slot. By setting the inclined surface 216, the front end surface of the key module 200 is blocked outside the installation slot, hiding the gap between the key module 200 and the installation slot.

[0048] The edge of the installation card slot is provided with a card slot flanging 110 extending inward, and a transition arc surface 111 is connected between the card slot flanging 110 and the box body 100.

[0049] And part or all of the transition arc surface 111 is located at the rear side of the inclined surface 216. The outer end of the inclined surface 216 blocks the gap between the key module 200 and the installation card slot, and the gap between the key module 200 and the box body 100 after being closed cannot be seen when viewed from the front of the washing machine. It is preferably set that part of the transition arc surface 111 is located at the rear side of the inclined surface 216, so that after the key module 200 is closed, the front end surface of the key module 200 is flush with the front end surface of the box body 100 at the installation card slot; wherein the box body 100 at the installation card slot is inclined upward and backward.

[0050] In this embodiment, the card slot flanging 110 has two horizontal card slot flangings located on the upper and lower sides of the installation card slot, and two vertical card slot flangings located on the left and right sides of the installation card slot. By setting the horizontal card slot flanging and the vertical setting, it is beneficial to ensure the pulling of the key module in the front and rear directions, and is beneficial to increasing the limiting and supporting effects.

[0051] The present invention further includes a washing machine, the washing machine includes a box body 100, the front end surface of the box body 100 is an integrated front panel, the installation card slot is opened on the front panel, the above-mentioned key module 200 is provided, and the front panel is an integrated sheet metal part. The integrated front panel can reduce the assembly process, improve the production efficiency, reduce the assembly gap, and improve the appearance beauty of the product.

[0052] In another embodiment, the washing machine includes a box body 100, the front end surface of the box body 100 is a front panel, and a main control panel arranged above the front panel. The installation card slot is arranged on the main control panel, and the above-mentioned key module 200 is provided.

[0053] The above embodiments only express several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention.
