[0001] The utility model relates to the technical field of household appliances, in particular to a computer board mounting structure and clothing processing equipment. Background Art

[0002] In modern household appliances, especially high-power, highly integrated products like clothes dryers, the computer board (PCB) serves as the core control component of the entire system. Its stability and reliability are directly related to the overall performance and lifespan of the device. PCBs typically consist of complex circuits, including processors, memory, interface circuits, and various sensors and control circuits. These components generate significant heat during operation. If this heat cannot be dissipated promptly and effectively, the board temperature will rise, affecting the performance of circuit components and even causing circuit failures, shortening the lifespan of the device.

[0003] Traditional computer board mounting structures often focus on securing and protecting the circuit board, while neglecting the importance of heat dissipation. While some designs do take heat dissipation into account, they often rely on natural cooling methods, such as adding heat sinks to the circuit board, convection between the heat sink and the surrounding air, or using materials with improved thermal conductivity for the circuit board substrate. However, these measures are still unable to meet the demand for rapid heat dissipation under high loads. Utility Model Content

[0042] 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.

[0043] like Figure 1 and Figure 2 As shown, the computer board 200 installation structure includes a mounting box 100 , a computer board 200 and a cooling fan 300 .

[0044] The installation box 100 includes a box body 110 and a box cover 120 located on one side of the box body 110. The box body 110 and the box cover 120 are fastened together to form a space for installing the computer board 200. A fan installation portion 1111 is provided on the installation box 100.

[0045] Computer board 200 is installed within mounting box 100. It contains components such as a processor, memory, and interface circuits, and is responsible for controlling the device. A heat sink 220 is mounted on computer board 200. Heat sink 220 is in close contact with the main heat-generating components on board 200 (such as the processor). Heat sink 220 is equipped with multiple fins to increase the heat dissipation area and improve heat dissipation efficiency.

[0046] The cooling fan 300 is mounted on the fan mounting portion 1111 and is located at one end of the heat sink 220 for driving air flow through the heat sink 220 .

[0047] like Figure 3 As shown, a heat dissipation vent 1110 is provided on the mounting box 100 near the other end of the radiator 220. Heat dissipation vent 1110 can be single or multiple. Heat dissipation vent 1110 is located at the other end of the radiator 220 to ensure smooth airflow through the radiator 220 and out of the mounting box 100. The size and shape of heat dissipation vent 1110 are optimized based on heat dissipation requirements and fan performance to ensure optimal heat dissipation.

[0048] When the cooling fan 300 is started, air is blown through the cooling fins of the radiator 220 to remove the heat generated by the computer board 200. The hot air is then discharged from the mounting box 100 through the heat dissipation vents 1110, thereby achieving an efficient heat dissipation effect.

[0049] The above-mentioned computer board 200 installation structure accelerates air flow and heat exchange of the radiator 220 by adding a cooling fan 300 to the installation box 100. At the same time, a heat dissipation port 1110 is opened at the other end of the radiator 220 to ensure that the airflow can pass through the radiator 220 smoothly and quickly and be effectively discharged outside the installation box 100, thereby significantly improving the heat dissipation efficiency.

[0050] In some embodiments, as Figure 1 The box body 110 is provided with openings 111 at both ends along its length. The connection terminals 230 on the computer board 200 can be arranged close to the openings 111 to facilitate wiring operations. At the same time, the openings 111 at both ends of the installation box 100 can further improve the heat dissipation effect.

[0051] In some embodiments, as Figure 2 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.

[0052] In some embodiments, see Figure 8 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 fixed by the fan clip structure. The design of the plug-in port 1112 and the fan clip structure allows for convenient installation of the cooling fan 300.

[0053] 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 heat dissipation fan 300. After the heat dissipation fan 300 is pushed into the fan mounting portion 1111 and into place, the elastic claw 1113 engages with the engaging hole 310.

[0054] See also Figure 9 The elastic claw 1113 is provided with an inclined surface at the position where it cooperates with the card hole 310 to facilitate the advancement of the cooling fan 300.

[0055] In order to securely install the cooling fan 300 , screw holes 1114 may be provided on the housing of the cooling fan 300 and the fan mounting portion 1111 , and the cooling fan 300 may be fastened to the fan mounting portion 1111 by screwing in a fastener (such as a screw).

[0056] 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 .

[0057] like Figure 5 As shown, since the cooling fan 300 is symmetrical in design, except for the wire opening, it is very easy to install it upside down. Therefore, a structure is designed on the installation box 100 to prevent the cooling fan 300 from being inserted incorrectly. Specifically, the plug-in port 1112 of the fan mounting portion 1111 is arranged toward the box cover 120. A baffle portion 124 is provided on the top of the box cover 120. When the box cover 120 is fastened to the box body 110, the baffle portion 124 covers the outside of the plug-in port 1112 and leaves space at one end of the plug-in port 1112 for routing the cooling fan wire harness ( Figure 5 The wire opening on the cooling fan 300 faces this space, allowing the wiring harness to pass through it. However, if the cooling fan 300 is installed upside down, the wire opening will be inside the baffle 124, preventing the cover 120 from closing. This serves as a reminder to the installer that the cooling fan 300 has been installed upside down.

[0058] When openings 111 are provided at both ends of the box body 110, the risk of water vapor and detergent splashing into the box body 110 is increased. In some embodiments, to enhance the waterproof performance, such as Figure 3 As shown, 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.

[0059] 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 .

[0060] In some embodiments, 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. That is, 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 interior of 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.

[0061] 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.

[0062] In some embodiments, as Figure 4 As shown, to further enhance the waterproof and drainage capabilities of the mounting box 100, one or more drain holes 121 are provided on the bottom surface of the box body 110 or the box cover 120. The design of the drain holes 121, combined with the inclined surface structure, effectively prevents moisture from accumulating within the box body 110, thereby improving the protection of the mounting box 100 in humid environments and the safety of the computer board 200.

[0063] In some embodiments, as Figure 5As 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.

[0064] In some embodiments, some wiring harnesses connected to computer board 200 can be routed inside innermost bottom water barrier 113 to prevent the wiring harnesses from being exposed to the outside. Mounting holes 1151 are located outside innermost bottom water barrier 113. Bottom water barrier 113 prevents the wiring harnesses from drifting into mounting holes 1151 and crushing them when tightening the screws.

[0065] 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.

[0066] A wire fixing buckle 116 may be provided on the installation box 100 to fix the wire harness.

[0067] 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.

[0068] In some embodiments, as Figure 7 As shown, at least two screw posts 118 are provided on the box body 110 for securing the computer board 200. Multiple positioning protrusions 117 are provided along the periphery 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. This not only limits the computer board 200 but also maintains a gap between the computer board 200 and the side of the box body 110 to facilitate glue filling later.

[0069] In some embodiments, in order to prevent the computer board 200 from being installed upside down, Figure 6As shown, a raised portion 119 is provided at one corner of the housing 110, and a clearance notch 210 is provided at one corner of the computer board 200 corresponding to the raised portion 119. If the computer board 200 is incorrectly placed upside down, the raised portion 119 will not align with the clearance notch 210, thus immediately alerting the installer and preventing problems such as incorrect circuit connections, functional failures, and even hardware damage caused by reverse installation, thereby improving installation efficiency and accuracy.

[0070] 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.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
