Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more specifically, to an electrical control box assembly structure and an air conditioner having the same. Background Technology

[0002] With economic development, air conditioners are becoming increasingly common. The outdoor unit of an air conditioner is typically placed outdoors. Inside the outdoor unit's electrical control box are integrated circuit boards and terminal boards, which connect to and control the indoor unit, and also provide a power interface for connecting to an external power source. The integrated circuit board is a crucial component for the air conditioner's operation; if damaged, the unit will not be able to start. Rainwater seeping into the unit during rainy weather will severely impact the air conditioner's lifespan and safety; therefore, a waterproof electrical control box is essential.

[0003] Traditionally, electrical control boxes are fixed by spot welding a mounting plate to the left side, which is then secured to the left side panel. The right side of the control box is fixed to the central column. Some products use two mounting plates on the left and right sides of the control box, resulting in more parts and significantly reducing production efficiency. Summary of the Invention

[0004] The problem solved by this invention is that, in the prior art, the electrical control box is prone to water ingress, which seriously affects the safety of electrical components. At the same time, the electrical control box has a complex assembly structure with many parts, which affects production efficiency.

[0005] To address the aforementioned problems, this invention discloses an electrical control box assembly structure, comprising an electrical control box body and a box cover. The electrical control box body includes a side wall, on which a folding structure with a groove is provided. The groove is recessed away from the box cover. A third folded edge is provided on the box cover, and the groove and the third folded edge are fitted together. A snap-fit ​​structure is provided between the groove and the box cover, and the snap-fit ​​structure is used for limiting the connection between the box cover and the electrical control box body.

[0006] The groove is assembled with the third folded edge. Because there is a distance difference in the front and back directions between the first sidewall and the second sidewall of the groove and the folded surface of the folded structure, rainwater cannot enter the interior of the electrical control box, and the rainwater can be discharged along the groove, thereby effectively improving the waterproof effect of the electrical control box.

[0007] Furthermore, the folding structure also includes at least a first folded edge, which is disposed on the side of the groove away from the side wall of the box. A first fixing structure is disposed on the first folded edge, which is used for the fixed assembly of the electrical control box in the unit.

[0008] This design eliminates the need for a mounting plate during the installation of the electrical control box, significantly reducing the number of parts required for installation and improving production efficiency.

[0009] Furthermore, the lower end of the cover is lower than the bottom plate of the electrical control box, and a first folding edge is provided at the lower end of the cover. The first folding edge extends toward the electrical control box, and an upwardly extending first folding edge is provided at the end of the extension direction of the first folding edge.

[0010] The first folded edge can serve to catch water, further improving the waterproof effect of the electrical control box. At the same time, the first folded edge ensures that water entering the first folded edge can only flow out from both sides, which helps to simplify the drainage structure on the base of the casing.

[0011] Furthermore, the snap-fit ​​structure includes a snap-fit ​​hole and a snap-fit ​​hook, with the snap-fit ​​hook extending into the snap-fit ​​hole to form a snap-fit.

[0012] The snap-fit ​​structure is designed to quickly and securely connect the cover to the electrical control box, thereby facilitating the subsequent fixed connection between the cover and the electrical control box.

[0013] Furthermore, the card hole is provided on the bottom surface of the groove, and the card hook is provided on the box cover.

[0014] This design makes the fitting and assembly of the hooks and holes simpler and faster. At the same time, rainwater that seeps in along the fitting gap of the snap-fit ​​structure can only enter the groove and be discharged along the groove, further improving the waterproof effect of the electrical control box.

[0015] Furthermore, the opening of the hook faces upward.

[0016] This design ensures that the hook and the hole are engaged and positioned from bottom to top, aligning with the assembly direction of the lid and the brim structure, thus facilitating the smooth assembly of the lid.

[0017] Furthermore, the folding structure also includes a second folded edge, which is disposed on the side of the groove near the side wall of the box body. A second fixing structure is disposed on the second folded edge, and a third fixing structure is disposed on the box cover. The second fixing structure and the third fixing structure are configured to cooperate with each other for the fixed connection of the electrical control box body and the box cover.

[0018] The electrical control box and the cover are fixedly connected after being limited by a snap-fit ​​structure, which can eliminate the step of alignment during the fixed connection, thereby speeding up the assembly speed of the fixed connection and improving production efficiency.

[0019] Furthermore, a top cover is provided on the upper end of the electrical control box, and a brim structure is provided on the circumference of the top cover, the brim structure being fitted onto the upper end of the box cover.

[0020] The design of the brim structure allows the seam between the box cover and the top cover to face downwards, which more effectively prevents rainwater from seeping in along the seam and enhances the waterproof performance of the electrical control box.

[0021] Furthermore, a fourth folded edge is provided on both sides of the box cover near the upper end. The fourth folded edge bends towards the electrical control box body and is inclined in the left-right direction. The end of the fourth folded edge near the electrical control box body is higher than the end near the groove.

[0022] This design allows rainwater intruding from the brim structure to flow into the groove along the inclined surface of the fourth fold, thus preventing it from entering the interior of the electrical control box and effectively improving the waterproof performance of the electrical control box.

[0023] The present invention also discloses an air conditioner, including the electrical control box assembly structure as described above. The air conditioner includes a unit side plate and a condenser. A fixed folded edge is provided on the unit side plate, and a side plate is provided on the condenser. A first connecting hole is provided on the first folded edge of the folding structure, a seventh connecting hole is provided on the fixed folded edge, and an eighth connecting hole is provided on the side plate. The first connecting hole cooperates with the seventh connecting hole and / or the eighth connecting hole.

[0024] The advantages of the air conditioner and the aforementioned electrical control box assembly structure compared to the prior art are the same, and will not be repeated here.

[0025] Compared with the prior art, the electrical control box assembly structure and the air conditioner having the same structure described in this invention have the following advantages:

[0026] This invention utilizes a folding structure with grooves on the electrical control box. During installation, the third fold on the box cover mates with this grooved folding structure, effectively waterproofing the electrical control box. Simultaneously, the folding structure can also be used to secure the electrical control box to the air conditioner housing, significantly reducing the number of parts required for fixing the box and improving production efficiency. This invention features a simple structure, convenient operation, and greatly improves the waterproof performance and assembly efficiency of the electrical control box. Attached Figure Description

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0056] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: an electrical control box assembly structure and an air conditioner having the same.

[0057] Example 1

[0058] This embodiment provides an electrical control box assembly structure, such as... Figures 1-6 , Figure 26As shown, the device includes an electrical control box body 1 and a box cover 2. The electrical control box body 1 includes a box body side wall 11. A folding structure with a groove 13 is provided on the box body side wall 11. The groove 13 is recessed in a direction away from the box cover 2. A third folded edge 22 is provided on the box cover 2. The groove 13 and the third folded edge 22 are fitted together. In existing technologies, most electrical control boxes are assembled by abutting a single flat surface when the box body 1 and cover 2 are joined. This method easily allows rainwater to seep into the box through gaps in the flat surface, affecting the operation of the internal electrical components. In this embodiment, the electrical control box body 1 includes two side walls 11. Each side wall 11 has a folding structure with a groove 13 on the side near the cover 2. The groove 13 mates with the third folded edge 22. Due to the distance difference between the first side wall 133 and the second side wall 134 of the groove 13 and the folding surface of the folding structure in the front-to-back direction, rainwater cannot enter the box and can drain out along the groove 13, thus effectively improving the waterproof effect of the electrical control box. It should be understood that the third folded edge 22 extends towards the electrical control box body 1 in the front-to-back direction. During assembly, the bottom surface 131 of the groove 13 abuts against the end of the third folded edge 22, forming a good sealing structure and further improving the waterproof effect of the electrical control box. Preferably, the second sidewall 134 of the groove 13 near the sidewall 11 of the box body is fitted to the inner surface of the third folded edge 22, which can more effectively prevent rainwater from entering the electrical control box from the side.

[0059] As one of the preferred embodiments, such as Figure 1 , Figure 2As shown, the folding structure further includes at least a first folded edge 12, which is disposed on the side of the groove 13 away from the side wall 11 of the box. A first fixing structure is provided on the first folded edge 12, which is used for the fixed assembly of the electrical control box in the unit. In an optional embodiment, the unit is an outdoor unit of an air conditioner. The first fixing structure can be fixedly connected to the housing of the unit and / or the device inside the unit. The housing of the unit includes a front panel and / or a side panel 3. A fixing folded edge 31 is provided on the side panel 3. A seventh connecting hole (not shown in the figure) is provided on the fixing folded edge 31. The device inside the unit may include a condenser. A side panel (not shown in the figure) is provided on the condenser. An eighth connecting hole (not shown in the figure) is provided on the side panel. The first connecting hole 121 cooperates with the seventh connecting hole and / or the eighth connecting hole to realize the fixed connection between the fixing folded edge 31 and / or the side panel and the first folded edge 12. This design eliminates the need for a fixing plate during the installation of the electrical control box, significantly reducing the number of parts required for the installation of the electrical control box 1 and improving production efficiency. In one embodiment, the first fixing structure is a first connecting hole 121, through which screws are used to fix the electrical control box. In an optional embodiment, the first folded edge 12 is simultaneously fixed with the side panel and condenser side panel of the air conditioner outdoor unit, improving the installation stability of the electrical control box, reducing the number of parts in the electrical control box fixing assembly structure, lowering production costs, and increasing production efficiency.

[0060] In this embodiment, as Figure 5 , Figure 18 As shown, the lower end of the cover 2 is lower than the bottom plate 17 of the electrical control box 1, and a first folding edge 25 is provided at the lower end of the cover 2. The first folding edge 25 extends toward the electrical control box 1, and an upwardly extending first folding edge is provided at the end of the extension direction of the first folding edge 25. In the prior art, the air inlet of the electrical control box is often located on the bottom plate 17 of the electrical control box body 1. If the lower end of the box cover 2 is flush with or higher than the bottom plate 17, rainwater flowing down the front side of the box cover 2 is likely to flow to the lower surface of the bottom plate 17. This will cause rainwater to be easily brought into the electrical control box when air is introduced. The setting of the first folding edge 25 can prevent this part of the rainwater from flowing to the bottom plate 17, thereby improving the waterproof effect of the electrical control box. In addition, the amount of water flowing down the groove 13 is large and it is easier to enter the area of ​​the bottom plate 17. The setting of the first folding edge 25 can play the role of catching water, further improving the waterproof effect of the electrical control box. At the same time, the setting of the first folding edge ensures that the water entering the first folding edge 25 can only flow out from both sides, which helps to simplify the drainage structure on the base of the casing.

[0061] As one of the alternative embodiments, such as Figure 2 , Figure 5 As shown, a snap-fit ​​structure is also provided between the groove 13 and the cover 2. The snap-fit ​​structure is used to quickly and securely connect the cover 2 to the electrical control box 1, thereby facilitating the subsequent fixed connection between the cover 2 and the electrical control box 1.

[0062] In this embodiment, as Figure 2 , Figure 5 As shown, the snap-fit ​​structure includes a snap-fit ​​hole 132 and a snap-fit ​​hook 21, with the hook 21 extending into the snap-fit ​​hole 132 to form a snap-fit. The hook 21 and snap-fit ​​hole 132 have a simple structure, are easy to manufacture, and have a good limiting effect. It should be understood that there is more than one snap-fit ​​structure to obtain a better limiting effect. The snap-fit ​​hole 132 can be entirely set on the groove 13, in which case the hook 21 is correspondingly set on the lid 2; or the snap-fit ​​hole 132 can be entirely set on the lid 2, in which case the hook 21 is correspondingly set on the groove 13; or the snap-fit ​​hole 132 can be partially set on the groove 13 and partially set on the lid 2, with the hook 21 and snap-fit ​​hole 132 correspondingly set on the lid 2 or the groove 13. It should be noted that the card hole 132 and / or card hook 21 provided on the groove 13 can be provided on any one of the groove bottom surface 131, the first side wall 133 and the second side wall 134 of the groove 13, and a good limiting effect can be obtained.

[0063] As a preferred embodiment, such as Figure 2 , Figure 5 As shown, the locking hole 132 is disposed on the bottom surface 131 of the groove 13, and the locking hook 21 is disposed on the cover 2. It should be understood that when the locking hole 132 is disposed on the cover 2, rainwater on the surface of the cover 2 can easily seep in through the fitting gap of the locking structure and seep into the inside of the electrical control box along the inner surface of the cover 2, affecting the waterproof effect of the electrical control box. This design makes the fitting and assembly of the locking hook 21 and locking hole 132 simpler and faster. At the same time, rainwater that seeps in along the fitting gap of the locking structure can only enter the groove 13 and be discharged along the groove 13, further improving the waterproof effect of the electrical control box.

[0064] As another embodiment, such as Figure 1 , Figure 6As shown, the folding structure further includes a second folded edge 14, which is disposed on the side of the groove 13 near the side wall 11 of the box body. A second fixing structure is provided on the second folded edge 14, and a third fixing structure is provided on the box cover 2. The second fixing structure and the third fixing structure are configured to cooperate for the fixed connection of the electrical control box body 1 and the box cover 2. As one optional embodiment, the second fixing structure is a third connecting hole 142, and the third fixing structure is a fourth connecting hole 23. The third connecting hole 142 and the fourth connecting hole 23 are fixedly connected by screws. It should be understood that the electrical control box body 1 and the box cover 2 are fixedly connected after being limited by the snap-fit ​​structure, which can eliminate the step of alignment during the fixed connection, thereby speeding up the assembly speed of the fixed connection and improving production efficiency.

[0065] Specifically in this embodiment, such as Figure 6 , Figure 10 As shown, a top cover 5 is provided on the upper end of the electrical control box 1, and a brim structure 52 is provided around the top cover 5. The brim structure 52 is fitted onto the upper end of the box cover 2. The brim structure 52 is designed so that the joint between the box cover 2 and the top cover 5 faces downward. Compared with the existing technology where the joint faces upward, this more effectively prevents rainwater from seeping in along the joint, thus enhancing the waterproof performance of the electrical control box.

[0066] In some optional embodiments, such as Figure 6 As shown, a fourth folded edge 24 is provided on both sides of the cover 2 near the upper end in the left-right direction. The fourth folded edge 24 bends towards the electrical control box 1 and is inclined in the left-right direction. The end of the fourth folded edge 24 near the electrical control box 1 is higher than the end near the groove 13. This arrangement allows rainwater entering from the brim structure 52 to flow into the groove 13 along the inclined surface of the fourth folded edge 24, thus preventing it from entering the interior of the electrical control box and effectively improving the waterproof performance of the electrical control box.

[0067] As one example, such as Figure 5 As shown, the hook 21 is disposed on the lid 2, and the opening of the hook 21 faces upward. It should be understood that, due to the setting of the brim structure 52 on the top cover 5 in this application, the lid 2 needs to be assembled from bottom to top during assembly. If the opening of the hook 21 faces downward, it will cause interference between the lid 2 and the brim structure 52, making assembly impossible. This setting ensures that when the hook 21 cooperates with the locking hole 132 for limiting, it is installed from bottom to top, which is consistent with the assembly direction of the lid 2 and the brim structure 52, thereby facilitating the smooth assembly of the lid 2.

[0068] As an optional embodiment, such as Figure 4As shown, a plurality of reinforcing moldings 122 are provided at the connection between the first folded edge 12 and the groove 13, and / or at the connection between the second folded edge 14 and the groove 13. The reinforcing moldings 122 are used to enhance the strength of the folded structure. Because the folded structure has many connecting structures, the reinforcing moldings 122 can effectively prevent these connecting structures from causing deformation of the folded structure, thus avoiding affecting the waterproof performance of the electrical control box. The reinforcing moldings 122 are either protrusions or recesses; preferably, they are V-shaped protrusions or recesses.

[0069] In existing technologies, components such as drive boards, filter boards, and reactors are typically fixed inside an electrical control box. Meanwhile, a main control board and terminal boards are mounted on a separate electrical control mounting plate 4 for easy external power supply wiring. The electrical control mounting plate 4 is usually located inside the electrical control box near the box cover 2, concealing the drive boards, filter boards, reactors, and other components within the box. Furthermore, the electrical control mounting plate 4 is fixed to the electrical control box body 1 with screws. When components inside the electrical control box are damaged, the entire electrical control mounting plate 4 must be removed before repair operations can be performed, which is complex and significantly impacts repair efficiency.

[0070] In this embodiment, as Figures 7-12 As shown, the device includes an electrical control box 1 and an electrical control mounting plate 4. A rotatable connection structure is provided between the electrical control box 1 and the electrical control mounting plate 4, allowing the electrical control mounting plate 4 to be rotatably connected to the electrical control box 1. This rotatable connection allows the electrical control mounting plate 4 to be rotatably opened relative to the electrical control box 1. Therefore, when it is necessary to repair or replace the components inside the electrical control box, it is not necessary to completely remove the electrical control mounting plate 4; simply rotating it open exposes the internal components, facilitating repair and replacement, reducing the disassembly and assembly time of the electrical control mounting plate 4, and simplifying the installation, repair, and replacement of the internal components of the electrical control box.

[0071] In one embodiment, such as Figure 11 , Figure 12 As shown, the electrical control box 1 includes a box side wall 11, and the electrical control mounting plate 4 includes a mounting plate side wall 41. The rotating connection structure is disposed between the box side wall 11 and the mounting plate side wall 41. Normally, the electrical control mounting plate 4 is perpendicular to the box side wall 11. Directly placing the rotating connection structure between them would affect the installation space for the main control board and terminal board on the electrical control mounting plate 4. The mounting plate side wall 41 allows the rotating connection structure to be placed between two connecting surfaces, thus providing sufficient installation space without affecting the installation of the main control board and terminal board on the electrical control mounting plate 4.

[0072] As one embodiment of the present invention, such as Figure 11, Figure 12 As shown, the rotating connection structure includes a connecting groove and a connecting shaft 114, with the connecting shaft 114 extending into the connecting groove to form a rotating connection. In this configuration, the connecting shaft 114 serves as the rotation shaft of the electrical control mounting plate 4. When components inside the electrical control box need repair or replacement, the electrical control mounting plate 4 rotates around the connecting shaft 114 to open, exposing the components behind it, which is simple and convenient. It should be understood that the connecting groove can be located on the electrical control box body 1 or on the side wall 41 of the mounting plate, and the connecting shaft 114 can be correspondingly located on either the side wall 41 of the mounting plate or the electrical control box body 1.

[0073] As one of the preferred embodiments, such as Figure 11 , Figure 12 As shown, the connecting groove is disposed on the side wall 41 of the mounting plate, and the connecting shaft 114 is disposed on the electrical control box 1. It should be understood that when the connecting groove is disposed on the electrical control box 1, a through hole will appear on the side wall 11 of the box, which can easily lead to rainwater intrusion and is detrimental to the waterproofing of the electrical control box. Disposing the connecting groove on the side wall 41 of the mounting plate and the connecting shaft 114 on the side wall 11 of the box can effectively avoid the above problems and ensure the waterproofing effect of the electrical control box.

[0074] Specifically in this embodiment, such as Figure 3 As shown, a first recessed platform 111 is provided on the side wall 11 of the box body, and a first through hole 112 is provided in the first recessed platform 111. The connecting shaft 114 is provided on the side wall 11 of the box body through the first recessed platform 111 and the first through hole 112. As one optional embodiment, the connecting shaft 114 is a pump foot bolt. The pump foot bolt is fixedly provided on the side wall 11 of the box body through the first recessed platform 111 and the first through hole 112. The head end of the pump foot bolt extends into the interior of the electrical control box to cooperate with the connecting groove to realize the rotational connection between the electrical control mounting plate 4 and the electrical control box body 1.

[0075] In some optional embodiments, such as Figure 7As shown, the connecting groove includes a first opening groove and a second opening groove. The opening end of the second opening groove is connected to the tail end of the first opening groove. The extending direction of the second opening groove forms an angle with the extending direction of the first opening groove. The opening end of the first opening groove forms the entrance of the connecting shaft 114. In this embodiment, the first opening groove is used for positioning when the electrical control mounting plate 4 is fixedly connected to the electrical control box 1, and the second opening groove is used to prevent the electrical control mounting plate 4 from falling off the electrical control box 1 when it is rotated open relative to the electrical control box 1. Specifically, the connecting shaft 114 enters from the open end of the first slot and can move relative to the first and second slots. In this configuration, the connecting shaft 114 entering from the open end of the first slot enables the rapid assembly of the electrical control mounting plate 4. At the same time, the connection between the open end of the second slot and the tail end of the first slot allows the connecting shaft 114 to move in different directions after entering the second slot. This configuration allows the connecting shaft 114 to be moved into the second slot when the device is rotated open, thus preventing the electrical control mounting plate 4 from easily detaching from the connecting slot when rotated open. This prevents the electrical control mounting plate 4 from separating from the electrical control box 1 when rotated open, ensuring that the electrical control mounting plate 4 can be quickly restored after the components inside the electrical control box have been repaired.

[0076] In some of the optional embodiments, such as Figure 7 As shown, the first opening slot is a vertical opening slot 411, and the second opening slot is a horizontal opening slot 412. This arrangement makes the extension directions of the first and second opening slots significantly different, which helps to select the moving direction of the electrical control mounting plate 4 during component maintenance. By moving it along the second opening slot and then rotating it to open, the electrical control mounting plate 4 can be effectively prevented from detaching from the electrical control box 1.

[0077] In one of the alternative embodiments, such as Figure 7 As shown, the vertical slot 411 is located below the horizontal slot 412. It should be understood that if the vertical slot 411 were located above the horizontal slot 412, the electrical control mounting plate 4 would require manual support during its fixed connection to ensure proper installation. This arrangement helps the connecting shaft 114 to provide support at the connection point between the horizontal slot 412 and the vertical slot 411, avoiding the need for manual support by assembly personnel and improving product assembly efficiency.

[0078] As one of the preferred embodiments, such as Figure 7As shown, the included angle between the vertical opening groove 411 and the horizontal opening groove 412 is between 75° and 85°. This arrangement allows the vertical opening groove 411 to be positioned below the horizontal opening groove 412, creating a high point at the tail end of the first opening groove and the opening end of the second opening groove, which facilitates rapid positioning when the electrical control mounting plate 4 and the electrical control box 1 are fixedly connected. Preferably, the included angle is 80°.

[0079] In one optional embodiment, a folding structure is provided on the front side of the box sidewall 11, a fourth fixing structure is provided on the folding structure, and a fifth fixing structure is provided on the mounting plate sidewall 41. The fourth fixing structure and the fifth fixing structure are fixedly connected in cooperation. It should be understood that the rotating connection structure is mainly used for the rotating connection between the electrical control mounting plate 4 and the electrical control box 1. Therefore, it is necessary to provide other fixing connection structures to prevent the electrical control mounting plate 4 from moving in the electrical control box and to ensure the installation stability of the electrical control mounting plate 4.

[0080] Specifically in this embodiment, such as Figure 3 , Figure 7 , Figure 8 As shown, the fourth fixing structure includes a second recessed platform 141 and a second connecting hole 1411 disposed on the second recessed platform 141. The fifth fixing structure includes a fifth folded edge 413 disposed on the side wall 41 of the mounting plate and a fifth connecting hole 4131 disposed in the fifth folded edge 413. The second recessed platform 141 and the fifth folded edge 413 are fitted together, and the second connecting hole 1411 and the fifth connecting hole 4131 are fitted together. In this embodiment, the second connecting hole 1411 and the fifth connecting hole 4131 are fixedly connected by screws to achieve a fixed connection between the electrical control mounting plate 4 and the electrical control box 1. In some preferred embodiments, when the connecting shaft 114 is located at the connection between the first open end and the second open end, the second countersunk 141 cooperates with the fifth folded edge 413, and the second connecting hole 1411 cooperates with the fifth connecting hole 4131. This arrangement can utilize the supporting effect of the connecting shaft 114 to achieve alignment between the fourth and fifth fixing structures, making the fixing process simple and quick. At the same time, when it is necessary to open the electrical control mounting plate 4, the screws are unscrewed, and the electrical control mounting plate 4 is moved so that the connecting shaft 114 enters the second open groove. At this time, rotating the electrical control mounting plate 4 will not cause it to fall off. The connecting shaft 114 is limited and abuts against the tail end face of the second open groove. It should be understood that when the second open groove is an open horizontal groove 412, the tail end face is the horizontal groove tail face 4121.

[0081] As a preferred embodiment, such as Figure 8 , Figure 12As shown, a notch 414 is provided on the lower side of the fifth fold 413. The notch 414 is provided to prevent the fifth fold 413 from interfering with the bottom plate 17 of the electrical control box 1, such as... Figure 12 As shown, the rotation radius of the electronic control mounting plate 4 can be effectively increased, thereby completely exposing the components on its rear side, which is beneficial for the maintenance and replacement of components.

[0082] like Figure 10 As described above, when it is necessary to open the electrical control mounting plate 4, first unscrew the screw in the fifth connecting hole 4131, then pull the electrical control mounting plate 4 outward so that the connecting shaft 114 enters the open transverse groove 412, and then rotate the electrical control mounting plate 4 downward to open it, so that the components on the back can be repaired or replaced.

[0083] In existing technology, the electrical control box contains numerous electrical components that generate heat during operation. If this heat is not dissipated in time, it can shorten the lifespan of the control board and severely affect the performance of the air conditioner. To achieve heat dissipation, air conditioners typically have air inlets and outlets to facilitate timely heat removal. Due to the action of the unit's fan, the internal circulating air flows from the outside to the inside and from bottom to top. Therefore, the outlet is usually located on the top cover 5 of the air conditioner. Considering that rainwater can easily enter the electrical control box through the outlet on the top cover 5, existing technology usually adds a sealed cover plate on the top cover 5, maintaining a certain distance between the cover plate and the top cover 5 to form an air duct to exhaust the heat-exchanged gas. However, the gap between the top cover 5 and the cover plate at the rear of the electrical control box is still easily invaded by rainwater, resulting in poor waterproofing. In addition, the structure of the top cover 5 and the cover plate is relatively complex, affecting the assembly speed of the air conditioner and increasing the cost of the electrical control box.

[0084] In this embodiment, as Figures 13-25As shown, the device includes an electrical control box 1, which comprises a cavity formed by two side walls 11, a bottom plate 17, and a rear plate 15. The tops of the two side walls 11 are higher than the top of the rear plate 15. A top cover 5 is provided at the top of the two side walls 11, forming a first gap 8 between the top cover 5 and the top of the rear plate 15. This arrangement allows hot air generated after heat exchange in the electrical control box 1 to be discharged outward through the first gap 8, eliminating the need for an exhaust vent on the top cover 5 and thus eliminating the need for a cover plate. Compared with the prior art, this saves a component, simplifies the assembly process, and reduces production costs. It should be noted that the top cover 5 can be integrally formed with the electrical control box 1 or separately. When it is integrally formed, since the top of the side wall 11 of the box is higher than the top of the rear plate 15, a first gap 8 is formed between the top of the top cover 5 and the top of the rear plate 15. When it is separately formed, a top opening 16 is formed at the top of the electrical control box 1, and the top cover 5 is placed on the top opening 16. Since the top of the side wall 11 of the box is higher than the top of the rear plate 15, a first gap 8 is formed between the top of the top cover 5 and the top of the rear plate 15.

[0085] As one of the preferred embodiments, such as Figure 10 , Figure 22 , Figure 24 As shown, the top cover 5 includes a top cover body 51, and a downwardly extending brim structure 52 is provided on the periphery of the top cover body 51. A second gap is maintained between the brim structure 52 on the rear side of the electrical control box 1 and the rear plate 15. In this embodiment, the brim structure 52 is sleeved on the circumferential outer side of the top of the electrical control box 1 to prevent rainwater from intruding into the electrical control box. In this arrangement, the second gap allows the brim structure 52 to have a certain waterproof effect on the first gap 8, while also ensuring that the first gap 8 can be vented smoothly.

[0086] As an optional embodiment, Figure 15 , Figure 16 , Figure 25 As shown, a rear cover plate 6 is also provided on the rear side of the electrical control box 1. The rear cover plate 6 includes a rear cover plate body 62, and a rear cover top 61 is provided on the upper side of the rear cover plate body 62. The cap structure 52 is sleeved on the rear cover top 61. First side flanges 64 are provided on both sides of the rear cover plate body 62. The first side flanges 64 are connected to the side wall 11 of the box body. A third gap is maintained between the rear cover plate body 62 and the rear plate 15. The first gap 8, the second gap, and the third gap are connected to form an airflow channel 10. The rear cover plate 6 can effectively protect the first gap 8 and the second gap, preventing rainwater from entering the electrical control box from the first gap 8 and the second gap, and significantly improving the waterproof performance of the electrical control box.

[0087] As one of the preferred embodiments, such as Figure 16 , Figure 20 , Figure 23 As shown, a plurality of exhaust ports 621 are provided on the rear cover plate body 62, and a lower sealing plate 65 is provided on the lower side of the rear cover plate body 62. The lower sealing plate 65 extends towards the rear plate 15 and is fitted to the rear plate 15. When the lower sealing plate 65 and exhaust ports 621 are not provided, the heat-exchanged gas will be completely discharged from the lower opening of the rear cover plate 6. On the one hand, the concentrated discharge of gas is not conducive to the dispersion of heat dissipation. On the other hand, the discharge of hot air through a single opening will cause the temperature near the opening to rise abnormally, which may easily affect the normal operation of the unit. Therefore, by providing the lower sealing plate 65 and exhaust ports 621, the gas in the airflow channel 10 is dispersedly discharged from the exhaust ports 621, making the exhaust more uniform and significantly improving the heat dissipation effect.

[0088] In one alternative embodiment, such as Figure 20 As shown, the vent 621 has an opening angle facing downwards. This design prevents rainwater from seeping into the electrical control box through the vent 621, ensuring the waterproof effect of the electrical control box.

[0089] Better, such as Figure 16 , Figure 23 As shown, a plurality of second through holes 651 are provided on the lower sealing plate 65. The second through holes 651 are used for exhaust and / or drainage. It should be understood that during the heat dissipation process of the electrical control box, condensation water is easily formed along the inner and outer walls of the rear cover plate body 62. Due to the presence of the lower sealing plate 65, the condensation water formed on the inner wall of the rear cover plate body 62 cannot be discharged smoothly. Long-term retention will produce an odor on the one hand, and easily cause corrosion of the electrical control box on the other hand, affecting the service life of the electrical control box. The setting of the second through holes 651 allows the condensation water to be discharged smoothly, so that the airflow channel 10 is always in a dry state. At the same time, the second through holes 651 can also discharge some of the heat-exchanged gas, increasing the exhaust efficiency of the rear cover plate 6.

[0090] As one of the preferred embodiments, such as Figure 15 , Figure 16 , Figure 23As shown, the rear cover plate 6 also includes a second folded edge 63, which is disposed on the lower side of the rear cover plate body 62. The front side of the second folded edge 63 is fitted against the rear plate 15 and extends away from the rear plate 15. At the tail end of the extension direction of the second folded edge 63, an upward second fold is provided. The second folded edge 63 is used to collect condensate or rainwater left on the rear cover plate body 62, preventing it from falling onto the components below. The setting of the second fold ensures that the collected water can only be discharged through both ends of the second folded edge 63, which helps to set a uniform drainage structure on the lower side.

[0091] As one embodiment of the present invention, such as Figure 25 As shown, a radiator 9 is also provided on the rear plate 15. The radiator 9 is located below the second folded edge 63, and the length of the second folded edge 63 is greater than the length of the radiator 9. The length of the second folded edge 63 refers to the distance between its two ends in the left-right direction. The length of the radiator 9 also refers to the distance between its two ends in the left-right direction. This arrangement prevents water draining from the two ends of the second folded edge 63 from dripping onto the radiator 9, thereby effectively protecting the radiator 9.

[0092] In another embodiment of the invention, such as Figure 19 , Figure 20 As shown, a connecting plate 7 is provided on the upper side of the top cover 5, and the connecting plate 7 is used for the fixed assembly of the electrical control box in the unit. In some optional embodiments, the connecting plate 7 is fixedly connected to the crossbeam 32 in the unit. The setting of the connecting plate 7 can further enhance the assembly stability of the electrical control box and the unit. In optional embodiments, the connecting plate 7 is fixedly connected to the top cover 5. In one optional embodiment, the connecting plate 7 and the top cover 5 are fixedly connected by welding.

[0093] In one embodiment, such as Figure 17 As shown, the connecting plate 7 includes a connecting plate body 71, on which a third folded edge 72 is provided. The third folded edge 72 is assembled with the crossbeam 32 of the unit. A sixth connecting hole 73 is also provided on the connecting plate body 71, which is used for fixed connection with the crossbeam 32. The third folded edge 72 is used for hooking and positioning with the crossbeam 32 so that the sixth connecting hole 73 can be aligned for fixed connection.

[0094] In other alternative embodiments, such as Figure 17As shown, the connecting plate 7 also includes a horizontal folded edge 75, which is fixedly connected to the top cover 5. Second side folded edges 74 are provided at both ends of the connecting plate 7 in the left-right direction. The second side folded edges 74 on the lower part of the horizontal folded edge 75 are fitted against the side wall 11 of the box body. The horizontal folded edge 75 increases the connection area between the connecting plate 7 and the top cover 5, thereby increasing their connection strength and enhancing the connection stability between the electrical control box and the unit. The second side folded edge 74 can cover the gap at the connection between the horizontal folded edge 75 and the top cover 5, preventing rainwater accumulation in the gap and ensuring the waterproof performance of the electrical control box.

[0095] As an optional embodiment, such as Figure 2 , Figure 3 As shown, a top flange 113 extending into the interior of the electrical control box 1 is provided at the top of the side wall 11 of the box body. The top flange 113 can increase the contact area between the side wall 11 of the box body and the top cover 5, thereby improving its supporting strength.

[0096] It should be noted that in this embodiment, the top cover 5 is fitted on the top of the rear cover plate 6, the electrical control box body 1, and the box cover 2. The brim structure 52 covers the top of the rear cover plate 6, the electrical control box body 1, and the box cover 2, and covers the gaps at their joints, which greatly improves the waterproof performance of the electrical control box.

[0097] In this embodiment, the top cover 5 is integrally formed with one or both of the rear cover plate 6 and the connecting plate 7, or the top cover 5, rear cover plate 6, and connecting plate 7 are separate components. Integrating the top cover 5 with one or both of the rear cover plate 6 and connecting plate 7 reduces the number of parts and improves the assembly efficiency of the electrical control box. Separating the top cover 5, rear cover plate 6, and connecting plate 7 significantly reduces the difficulty of mold manufacturing and also significantly reduces mold opening costs. In some optional embodiments, when the top cover 5, rear cover plate 6, and connecting plate 7 are separate components, the top cover 5 and rear cover plate 6, and the top cover 5 and connecting plate 7, can be fixedly connected by welding or riveting, which will not be elaborated further here.

[0098] In some optional embodiments, such as Figure 20 As shown, the rear cover body 62, lower sealing plate 65, and second folded edge 63 are integrally formed. Meanwhile, one side of the lower sealing plate 65 and the second folded edge 63 are fitted to the rear plate 15, which simplifies the production and assembly steps of the rear cover 6.
