Therefore, they should not be construed as limitations on the embodiments of this application.

[0030] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings, so as to understand in detail how to solve the problems raised in the background art.

[0031] It should be noted that: In this embodiment, the electrical appliance has a casing, which includes a top cover and four side panels connected to each other. The display panel 1 can be installed on the top cover or the four side panels as needed. At the same time, a notch is made at the location where the display panel 1 is installed. The top cover or the four side panels can be formed by stamping metal sheets. The following is a detailed explanation using the example of the display panel 1 being fixed to the top cover.

[0032] like Figures 1 to 5 As shown, a display panel 1 structure for an electrical appliance includes a display panel 1 fixed to a top cover. The display panel 1 includes a mounting box 2 fixedly installed with the top cover and an operation panel 3 installed in the mounting box 2. The top surface of the mounting box 2 is provided with a protruding ring 21, a first groove 22 formed by the protruding ring 21, and a glue applicator 23 located below the first groove 22. The first groove 22 and the glue applicator 23 are connected. The glue applicator 23 is used to hold glue. The distance between the bottom surface of the first groove 22 and the top surface of the protruding ring 21 is less than the thickness of the operation panel 3. The protruding ring 21 is provided with a second groove 24. A sealing ring 4 is located in the second groove 24. The operation panel 3 is covered by the first groove 22. The sealing ring 4 is tightly fitted to the top cover.

[0033] With the above solution, in practical application, glue can be applied to the glue application groove 23 first, and then the operation panel 3 can be placed in the first groove 22 and pressed tightly, so that the operation panel 3 and the glue in the glue application groove 23 are bonded and sealed, that is, the operation panel 3 and the mounting box 2 are sealed and connected, improving the sealing performance of the display panel 1. Then, a sealing ring 4 can be placed in the second groove 24 of the convex ring 21. The sealing ring 4 can be a silicone strip. Based on the elastic force of the sealing ring 4, the sealing ring 4 is fitted onto the outer wall of the operation panel 3. When the mounting box 2 is fixed to the top cover, the convex ring 21 and the top cover can press the sealing ring 4 tightly from top to bottom, realizing the connection between the display panel 1 and the electrical housing. Regarding the sealing performance, it is worth noting that since the sealing ring 4 is a silicone synthetic elastomer, it will deform when subjected to external forces of clamping from above and below. In order to maintain its overall volume unchanged or approximately unchanged, the sealing ring 4 will expand in the left and right directions, strengthening the tight fit between the sealing ring 4 and the operation panel 3. This achieves initial sealing of the gap between the display panel 1 and the top cover, further enhancing the sealing performance between the display panel 1 and the top cover, and also preventing dust from entering. After the external force is removed, the sealing ring 4 can return to its original shape. This significantly improves the waterproof effect of the electrical appliance, avoids short circuits in the display panel 1, and ensures the service life of the electrical appliance.

[0034] In this embodiment, the mounting box 2 is embedded into the outer wall surface of the top cover from the inner wall surface. The mounting box 2 can be injection molded from plastic material, and the glue is injected by a glue applicator. At the same time, the glue can be a waterproof fixing glue, which can play a fixing and sealing role. The protruding ring 21, the first groove 22, the glue applicator groove 23 and the second groove 24 are all formed by sequentially slotting after setting a rectangular protrusion on the upper surface of the mounting box 2. The first groove 22 is a rectangular groove, the glue applicator groove 23 is an annular groove, and the second groove 24 is an arc groove, so that the side of the mounting box 2 and the protruding ring 21 form a flange edge, which is conducive to the fitting of the mounting box 2 with the inner wall surface of the top cover.

[0035] like Figure 2 As shown, in one specific embodiment of the improvement, a plurality of overflow grooves 25 are provided between the glue dispensing groove 23 and the inner wall of the convex ring 21. The overflow grooves 25 are respectively connected to the glue dispensing groove 23 and the first groove 22. Specifically, the overflow grooves 25 can be rectangular, arc-shaped, or trapezoidal. After the glue dispensing machine dispenses glue, some glue can enter the overflow grooves 25, which can further enhance the firmness between the operation panel 3 and the mounting box 2, so as to ensure the sealing of the display panel 1.

[0036] like Figure 2 As shown, in one specific embodiment of the improvement, the mounting box 2 is provided with multiple screw slots 26. Specifically, the screw slots 26 are provided in the flange plate of the mounting box 2, and there are 6 screw slots 26 distributed at the four corners and the center. The screw slots 26 have screw holes 322 that penetrate the flange edge. Correspondingly, the bottom surface of the top cover can be provided with 6 corresponding cylindrical structures, and the cylindrical structures are also provided with screw holes 322. When the mounting box 2 needs to be fixed to the top cover, the cylindrical structures can be inserted into the screw slots 26 to achieve precise positioning, and then the two can be fixedly connected by screws. This facilitates the precise insertion of the operation panel 3 into the notch of the top cover and is beneficial for the quick assembly and disassembly of the display panel 1.

[0037] like Figure 2As shown, in one specific embodiment of the improvement, the mounting box 2 is further provided with a receiving groove 27 placed in the glue application groove 23, and the receiving groove 27 is connected to the first groove 22. The operation panel 3 includes a tempered glass film 31 and a light guide bracket 32 ​​connected vertically. The tempered glass film 31 covers the first groove 22, and the light guide bracket 32 ​​is received in the receiving groove 27. Specifically, the tempered glass screen protector 31 can be made of tempered glass, thus making it resistant to aging. The light guide bracket 32 ​​can be made of plastic. The receiving groove 27 is also located below the first groove 22, and the top surfaces of the receiving groove 27 and the glue application groove 23 are coplanar, and the top surfaces of both are coplanar with the bottom surface of the first groove 22. This ensures the stability of the tempered glass screen protector 31 when placed horizontally, and also ensures the adhesive area between the tempered glass screen protector 31 and the mounting box 2. It is worth noting that the glue application groove 23 has a flat section between it and the receiving groove and the inner wall of the convex ring, which can prevent the glue from spreading when the tempered glass screen protector 31 is pressed into the first groove 22, and can prevent the glue from entering the interior of the mounting box 2.

[0038] like Figure 3 and Figure 4 As shown, in one specific embodiment of the improvement, the light guide bracket 32 ​​is provided with a plurality of light guide holes 321 at intervals. Specifically, the light guide holes can be rectangular or triangular. Based on the connection between the circuit board 5 and the light guide bracket 32, different colored light beads are set on the circuit board 5 at the corresponding light guide holes 321, which can reduce the interference of strong light. The interval arrangement of adjacent light guide holes can prevent light diffusion, avoid mutual interference between adjacent light guide holes, and improve the practicality of the display panel 1.

[0039] like Figures 3 to 5 As shown, in one specific embodiment of the improvement, the display panel 1 also includes a circuit board 5 disposed below the operation panel 3. The circuit board 5 is housed in a receiving groove 27 and has multiple through holes 51. The light guide bracket 32 ​​has multiple screw holes 322, and the receiving groove 27 has multiple screw posts 28. The screw holes 322, through holes 51, and screw posts 28 are arranged coaxially. Specifically, the circuit board 5 can be configured such that electronic components are mounted on one side and the other side is bonded to tempered glass. In this case, the light guide bracket 32 ​​can be bonded to the tempered glass, avoiding damage to the electronic components by squeezing. The tempered glass also has through holes 51. There are six screw holes 322, six through holes 51, and six screw posts 28. The screw posts 28 have through holes, so that screws can pass through the screw posts 28 and through holes 51 in sequence and then be fixed in the screw holes 322. This achieves the fixed installation of the light guide bracket 32 ​​and the circuit board 5, which is beneficial for the quick disassembly and assembly and subsequent maintenance of the display panel 1.

[0040] like Figures 3 to 5As shown, in one specific embodiment of the improvement, the light guide bracket 32 ​​is further provided with a positioning post 323, and the circuit board 5 is further provided with a positioning hole 52. The positioning post 323 and the positioning hole 52 correspond vertically. Specifically, the positioning post 323 is a cylindrical rod, and the connection and position setting of the positioning post 323 and the positioning hole 52 are corresponding. When the circuit board 5 and the light guide bracket 32 ​​are fixed, the positioning post 323 can be inserted into the positioning hole 52 first to achieve precise positioning, ensuring that each light bead can correspond to the corresponding light guide hole 321, and the screws can be fixed.

[0041] like Figure 1 and Figure 3 As shown, in one specific embodiment of the improvement, there is a gap 6 between the bottom surface of the receiving groove 27 and the circuit board 5. Specifically, the mounting shell can be made of high-temperature resistant plastic material, such as polyphenylene sulfide (PPS) and polyethersulfone (PES). The gap 6 can effectively insulate against heat and prevent damage to the circuit board 5. At the same time, the circuit board 5 is housed in the mounting box 2, and the receiving groove 27 of the mounting box 2 has openings on both sides for cable insertion, which can also facilitate ventilation and heat dissipation.

[0042] It is worth noting that the display panel 1 in this embodiment is used in the dryer, that is, it is installed in the outer shell of the dryer. In real life, most people often place the dryer or washing machine on the balcony, which makes the dryer prone to water ingress after rain. The structure of the display panel 1 in this application solves the above problem well.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
