[0039] Reference Figures 1-9 , which are some embodiments of the computer board mounting structure of the present invention. The computer board mounting structure is an important part of the main control board assembly of clothes processing equipment such as washing machines and clothes dryers, and is installed behind the main control board of the equipment.

[0040] like Figure 1 and Figure 2 As shown, the computer board 200 installation structure includes a mounting box 100 and a computer board 200 .

[0041] The installation box 100 consists of a box body 110 and a box cover 120, which snap together to form an enclosed space for installing the computer board 200. The installation box 100 is generally a rectangular parallelepiped structure, with the box cover 120 located on one side of the box body 110. When the installation box 100 is installed on the clothing processing device, the side where the box cover 120 is located is the front side, and the side where the box body 110 is located is the rear side.

[0042] At least one end of the box body 110 along the length direction is provided with an opening 111 for easy access of wires. To facilitate wiring, openings 111 may be provided at both ends of the box body 110 .

[0043] To enhance waterproof performance, a downwardly extending water retaining eave 112 is provided on the outer side of the upper portion of the opening 111. When water flows to the top surface of the installation box 100, it will flow outward through the water retaining eaves 112 on both sides. At the same time, at least one bottom water retaining rib 113 extending along the width direction of the installation box 100 is provided at the lower portion of the opening 111 to play a water retaining role.

[0044] The computer board 200 is fixed on the side of the box body 110 facing the box cover 120 and is located inside the water retaining eaves 112 and the bottom water retaining ribs 113, that is, within the protection range of the water retaining eaves 112 and the bottom water retaining ribs 113. The wiring terminals 230 on the computer board 200 are arranged near the opening 111 to facilitate wiring operation.

[0045] In the above-mentioned computer installation structure, the upper edge of the opening 111 of the installation box 100 is provided with a downward water retaining eaves 112 structure, which can effectively intercept and guide water droplets dripping from above, preventing them from entering the box body 110 through the opening 111 and causing damage to the computer board 200; at the same time, the setting of the bottom water retaining rib 113 blocks the water flow from the bottom into the box body 110, further enhancing the overall waterproof performance and ensuring the stable operation of the computer board 200 in a humid working environment.

[0046] In some embodiments, as Figure 3 As shown, the top of the box body 110 is provided with a top water retaining rib 114, which is arranged along the top edge of the box body 110 and the edge of the water retaining eave 112. In other words, the top water retaining rib 114 is arranged along the top edge of the box body 110, passes through the entire top of the box body 110, and extends to the edge of the water retaining eave 112. The top water retaining rib 114 can prevent the top water flow from flowing into the box body 110 along the connecting gap between the box body 110 and the box cover 120, and guide the water flow along the top of the box body 110 and the water retaining eave 112 to flow to both sides, further enhancing the overall waterproof performance of the installation box 100. At the same time, the top water retaining rib 114 also further enhances the structural stability of the box body 110.

[0047] In some embodiments, to ensure that accumulated water inside the box body 110 can be drained smoothly, the bottom surface of the box body 110 is designed as an inclined surface a that is inclined toward the box cover 120. This inclined design can guide the accumulated water in the box body 110 to flow naturally to one side, preventing water from accumulating inside the box body 110, thereby further improving the waterproof performance of the computer board 200.

[0048] In some embodiments, in order to further enhance the waterproof and drainage function of the installation box 100, as shown in FIG. Figure 4As shown, one or more drain ports 121 are provided on the bottom surface of the box cover 120. The design of the drain ports 121, combined with the inclined surface structure, effectively prevents moisture from accumulating within the box body 110, enhancing the protection of the mounting box 100 in humid environments and the safety of the computer board 200. In other embodiments, the drain ports may be provided on the box body 110.

[0049] In some embodiments, as Figure 5 As shown, outwardly extending bosses 115 are provided at both ends of the bottom of the box body 110, and mounting holes 1151 are provided on the bosses 115 for securing the installation box 100. The bosses 115 not only enhance the stability of the installation box 100 but also further improve the structural strength of the bottom, ensuring that the installation box 100 will not easily deform or loosen during installation. Furthermore, bottom water retaining ribs 113 are provided on the bosses 115 to prevent water from flowing from the bosses 115 into the interior of the box body 110.

[0050] In some embodiments, the portion of the wiring harness connecting to computer board 200 (the red harness on the right) can be routed inside the innermost bottom water barrier 113 to prevent exposure. Mounting holes 1151 are located outside the innermost bottom water barrier 113. This prevents the wiring harness from drifting into the area around mounting holes 1151 and potentially crushing it when tightening the screws.

[0051] The dual function of bottom water retaining rib 113 significantly improves the reliability of the device. On the one hand, it blocks the intrusion of moisture or detergent residue; on the other hand, it effectively isolates the wiring harness from the mounting hole 1151 area, ensuring that the wiring harness is away from the mounting hole 1151 and preventing damage caused by screw manipulation.

[0052] A wire fastening buckle 116 can be provided on the installation box 100 to fix the wiring harness. Specifically, the wire fastening buckle 116 can be provided on the inner side of the water retaining eaves, which can provide a certain degree of protection for the wiring harness.

[0053] In some embodiments, a wire opening 122 is provided at the bottom side of the cover 120 of the installation box 100, allowing the wiring harness to be routed laterally along the length of the installation box 100. This side-exit arrangement avoids the risk of friction with the device enclosure during forward exit, effectively protecting the integrity of the wiring harness. It also prevents the wiring harness from making sharp 90° bends during exit, preventing damage to the wires due to excessive bending.

[0054] In some embodiments, see Figure 8The box body 110 is provided with one or more screw columns 118 for fixing the computer board 200. A plurality of positioning protrusions 117 are provided along the edge of the side of the box body 110 facing the box cover 120. The computer board 200 is positioned and supported on the positioning protrusions 117. On the one hand, it has a limiting effect on the computer board 200, and on the other hand, it maintains a gap between the computer board 200 and the side of the box body 110 to facilitate the subsequent glue filling.

[0055] In some embodiments, as Figure 7 To prevent computer board 200 from being installed upside down, a raised portion 119 is provided on one corner of case 110, and a clearance notch 210 is provided on one corner of computer board 200 corresponding to raised portion 119. If computer board 200 is incorrectly placed upside down, raised portion 119 will not align with clearance notch 210, immediately alerting the installer. This prevents potential problems such as incorrect circuit connections, functional failures, and even hardware damage caused by reversed installation, improving installation efficiency and accuracy.

[0056] In order to improve the heat dissipation performance of the mounting box 100, see Figure 1-Figure 3 In some embodiments, a cooling fan 300 is further provided on the installation box 100. A fan mounting portion 1111 is provided on the installation box 100. The computer board 200 is provided with a radiator 220. The cooling fan 300 is installed on the fan mounting portion 1111 and is located at one end of the radiator 220 to drive air flow through the radiator 220. Figure 3 A heat dissipation vent 1110 is provided on the mounting box 100 near the other end of the radiator 220. This vent 1110 can be single or multiple. Located at the other end of the radiator 220, this vent ensures smooth airflow through the radiator 220 and out of the mounting box 100. When the cooling fan 300 is activated, it blows air through the fins of the radiator 220, removing heat generated by the computer board 200. The hot air is then discharged from the mounting box 100 through the heat dissipation vent 1110, achieving efficient heat dissipation.

[0057] In some embodiments, the openings 111 at both ends of the mounting box 100 not only facilitate wiring but also further improve heat dissipation.

[0058] In some embodiments, as Figure 2 As shown, a relatively large notch 123 is provided on the side of the box cover 120 facing the box body 110. By providing the relatively large notch 123, the heat blocking effect of the box cover 120 is greatly weakened, thereby further improving the heat dissipation effect.

[0059] See also Figure 8To facilitate installation and removal of the cooling fan 300, in some embodiments, a plug-in port 1112 is provided on one side of the fan mounting portion 1111. The cooling fan 300 is inserted into the fan mounting portion 1111 through the plug-in port 1112 and secured therein via a fan snap-fit ​​structure. The design of the plug-in port 1112 and the fan snap-fit ​​structure facilitates convenient installation of the cooling fan 300.

[0060] Specifically, the fan engaging structure includes an elastic claw 1113 provided on the fan mounting portion 1111 and a corresponding engaging hole 310 provided on the housing of the cooling fan 300. After the cooling fan 300 is pushed into the fan mounting portion 1111, the elastic claw 1113 engages with the engaging hole 310. The engaging hole 310 can be a screw fixing hole originally provided on the cooling fan.

[0061] See also Figure 9 The elastic claw 1113 is provided with an inclined surface b at a position matching the clamping hole 310 to facilitate the advancement of the cooling fan 300.

[0062] To ensure secure installation of the cooling fan 300, screw holes 1114 can be provided on the housing of the cooling fan 300 and on the fan mounting portion 1111. By inserting a fastener (e.g., a screw), the cooling fan 300 can be fastened to the fan mounting portion 1111. The cooling fan's fan clamping structure and a single fastener can secure the fan, making installation and removal convenient.

[0063] In some embodiments, the heat dissipation vent 1110 is located at the bottom of the box body 110 , and the fan mounting portion 1111 is disposed at the top of the box body 110 .

[0064] Since the cooling fan 300 is symmetrical in design except for the wire port, it is very easy to install it upside down. Therefore, a structure for preventing the cooling fan 300 from being inserted incorrectly is designed on the installation box 100. Specifically, Figure 5 As described, the plug port 1112 of the fan mounting portion 1111 faces the cover 120. A baffle 124 is located on top of the cover 120. When the cover 120 is engaged with the housing 110, the baffle 124 covers the outside of the plug port 1112. A space (circled in gray) is left at one end of the plug port 1112 for routing the cooling fan wiring harness. The wire opening on the cooling fan 300 faces this space, allowing the wiring harness to pass through it. If the cooling fan 300 is installed upside down, the wire opening will be on the inside of the baffle 124, preventing the cover 120 from engaging, thus providing a timely reminder to the installer that the cooling fan 300 has been installed upside down.

[0065] The present invention also includes a clothes processing device including the computer board mounting structure. The clothes processing device includes but is not limited to a clothes dryer, a washing machine, a shoe washer, etc.
