Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to a waterproof heat dissipation structure of an electric control box and an air conditioner having the same. Background Art

[0002] With economic development, the use of air conditioners is becoming increasingly common. The outdoor unit is typically placed outdoors. The outdoor unit's electrical control box houses electrical components such as an integrated circuit board and terminal block, which connect and control the indoor unit. These components also function as a power interface for an external power source. When the air conditioner is operating, these components generate heat. If the air conditioner runs for extended periods, this heat accumulates in the components. If this heat cannot be dissipated promptly, the air conditioner may malfunction, shorten the life of the control board, and severely impact its performance.

[0003] In order to achieve the purpose of heat dissipation of electrical components, the electrical control box is usually provided with openings to facilitate timely heat dissipation. However, if rainwater seeps into the unit during rainy days, it will seriously affect the life and safety of the air conditioner. Summary of the Invention

[0004] The problem solved by the present invention is that, in the prior art, in order to ensure the heat dissipation of electrical components, an opening is provided on the electric control box, and rainwater easily penetrates into the electric control box through the opening, affecting the life and safety of the air conditioner.

[0005] To solve the above problems, the present invention discloses a waterproof heat dissipation structure for an electric control box, comprising an electric control box body, wherein the electric control box body comprises a cavity formed by two box body side walls, a bottom plate and a back plate, wherein the top ends of the two box body side walls of the electric control box body are higher than the top end of the back plate, and a top cover is provided at the top ends of the two box body side walls, forming a first gap between the top cover and the top end of the back plate.

[0006] The hot air generated after heat exchange in the electric control box body is discharged outward from the first gap. This arrangement does not require an exhaust hole on the top cover, and therefore does not require a cover plate. Compared with the prior art, a component is saved on the top of the electric control box body, which simplifies the assembly process and reduces production costs.

[0007] Furthermore, the top cover includes a top cover body, a brim structure extending downward is provided on the circumference of the top cover body, and a second gap is maintained between the brim structure on the rear side of the electric control box body and the rear plate.

[0008] The provision of the second gap enables the brim structure to have a certain waterproof effect on the first gap, while also ensuring that the first gap can be smoothly vented.

[0009] Furthermore, a rear cover is provided on the rear side of the electric control box body, the rear cover includes a rear cover body, a rear cover top is provided on the upper side of the rear cover body, the brim structure is sleeved on the rear cover top, and first side folds are provided on both sides of the rear cover body, the first side folds are connected to the side walls of the box body, and a third gap is maintained between the rear cover body and the rear plate, and the first gap, the second gap, and the third gap are connected to form an air flow channel.

[0010] The arrangement of the rear cover can effectively protect the first gap and the second gap, thereby preventing rainwater from entering the electric control box through the first gap and the second gap, and significantly improving the waterproof performance of the electric control box.

[0011] Furthermore, a plurality of exhaust ports are provided on the rear cover body, and a lower sealing plate is provided on the lower side of the rear cover body. The lower sealing plate extends toward the rear plate and is fitted with the rear plate.

[0012] This arrangement enables the gas in the air flow channel to be discharged from the exhaust port in a dispersed manner, so that the exhaust gas is more evenly dispersed, and the heat dissipation effect is significantly improved.

[0013] Furthermore, the opening angle of the exhaust port is downward.

[0014] This arrangement can prevent rainwater from penetrating into the interior of the electric control box through the exhaust port, thereby ensuring the waterproof effect of the electric control box.

[0015] Furthermore, the rear cover plate also includes a second folded edge, which is arranged on the lower side of the rear cover plate body. The front side of the second folded edge is arranged in contact with the rear plate and extends away from the rear plate. At the tail end of the extension direction of the second folded edge, an upward second folded edge is provided.

[0016] The provision of the second flange allows the collected water to be discharged only through the two ends of the second flange, which helps to provide a unified drainage structure on the lower side.

[0017] Furthermore, a radiator is provided on the rear plate. The radiator is provided on the lower side of the second folded edge. The length of the second folded edge is greater than the length of the radiator.

[0018] This arrangement prevents water discharged from both ends of the second folded edge from dripping onto the radiator, thereby effectively protecting the radiator.

[0019] Furthermore, a top folded edge extending toward the interior of the electronic control box body is provided at the top end of the side wall of the box body.

[0020] The provision of the top fold can increase the contact area between the side wall of the box body and the top cover, thereby improving the supporting strength thereof.

[0021] The present invention also discloses an air conditioner, comprising the above-mentioned waterproof heat dissipation structure of the electric control box. The air conditioner comprises a crossbeam, and a connecting plate is provided on the upper side of the top cover. The connecting plate is assembled in cooperation with the crossbeam.

[0022] The connecting plate is fixedly connected to the crossbeam in the unit, and the provision of the connecting plate can further enhance the assembly stability of the electric control box and the unit.

[0023] Furthermore, the connecting plate includes a connecting plate body, a third folding edge is provided on the connecting plate body, the third folding edge is assembled with the crossbeam of the unit, and a sixth connecting hole is also provided on the connecting plate body, the sixth connecting hole is used for fixed connection with the crossbeam.

[0024] The third folded edge is used to be hooked and positioned with the crossbeam so as to facilitate fixed connection after the sixth connecting hole is aligned.

[0025] Compared with the prior art, the waterproof heat dissipation structure of the electric control box and the air conditioner having the same described in the present invention have the following advantages:

[0026] The present invention provides a first gap between the top opening of the electric control box body and the top cover, so that the air outlet structure of the electric control box can be formed by only providing a top cover. The provision of the rear cover effectively prevents rainwater from entering the interior of the electric control box through the first gap, thereby improving the waterproof effect of the electric control box. The provision of the exhaust port ensures the heat dissipation effect of the electric control box. The provision of the second folded edge and the second through hole allows condensation water or rainwater flowing down the rear cover to be smoothly discharged, thereby preventing water accumulation inside the rear cover. The present invention has a simple structure and is easy to install. It greatly improves the waterproof effect while ensuring the heat dissipation effect of the electric control box.

DETAILED DESCRIPTION

[0055] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. It should be noted that, unless there is a conflict, the features in the embodiments and embodiments of the present invention may be combined with each other.

[0056] In the prior art, the electrical control box is equipped with many electrical components, which generate heat during operation. If the heat is not dissipated in time, it is easy to shorten the life of the control board and seriously affect the performance of the air conditioner. In order to achieve the purpose of heat dissipation of the air conditioner, the air conditioner is usually provided with an air inlet and an exhaust hole to facilitate the timely discharge of heat. Due to the action of the unit fan, the circulating air inside the air conditioner flows from the outside to the inside and from the bottom to the top. Therefore, the exhaust hole is usually set on the top cover 5 of the air conditioner. Considering that rainwater can easily enter the interior of the electrical control box through the exhaust hole on the top cover 5 when it invades, the prior art usually provides a sealed cover plate on the upper side of the top cover 5, and maintains a certain distance between the cover plate and the top cover 5, thereby forming an air duct to discharge the heat exchanged gas. However, at the rear side of the electrical control box, the gap between the top cover 5 and the cover plate is still easily invaded by rainwater, resulting in poor waterproof effect. In addition, the structure of the top cover 5 and the cover plate is relatively complicated, which affects the assembly speed of the air conditioner and increases the cost of the electrical control box.

[0057] A waterproof heat dissipation structure of an electric control box and an air conditioner having the same according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] Example 1

[0059] This embodiment provides a waterproof heat dissipation structure of an electric control box, such as Figure 1 、 Figure 13-Figure 25As shown, the electronic control box 1 includes an electrical control box 1 comprising a cavity enclosed by two side walls 11, a bottom plate 17, and a rear plate 15. The tops of the two side walls 11 of the electronic control box 1 are higher than the top of the rear plate 15. A top cover 5 is provided at the tops 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 within the electronic control box 1 to be discharged outward through the first gap 8, eliminating the need for exhaust holes in the top cover 5 and, consequently, a cover plate. Furthermore, compared to the prior art, this eliminates a component at the top of the electronic control box 1, simplifying the assembly process and reducing production costs. It should be noted that the top cover 5 can be integrally provided with the electric control box body 1 or separately provided. When it is integrally provided, since the top end of the box body side wall 11 is higher than the top end of the rear plate 15, a first gap 8 is formed between the top cover 5 and the top end of the rear plate 15; when it is separately provided, a top end opening 16 is formed at the top end of the electric control box body 1, and the top cover 5 is covered on the top end opening 16. Since the top end of the box body side wall 11 is higher than the top end of the rear plate 15, a first gap 8 is formed between the top cover 5 and the top end of the rear plate 15.

[0060] As one of the preferred embodiments, Figure 10 、 Figure 22 、 Figure 24 As shown, the top cover 5 includes a top cover body 51, with a downwardly extending brim structure 52 disposed around 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 body 1 and the rear plate 15. In this embodiment, the brim structure 52 is sleeved around the circumferential outer side of the top of the electrical control box body 1 to prevent rainwater from invading the electrical control box. In this arrangement, the provision of the second gap ensures that the brim structure 52 provides a certain waterproof effect for the first gap 8, while also ensuring smooth air discharge from the first gap 8.

[0061] As an optional embodiment, Figure 15 、 Figure 16 、 Figure 25As shown, a rear cover plate 6 is further provided on the rear side of the electric control box body 1. The rear cover plate 6 includes a rear cover plate body 62. A rear cover top 61 is provided on the upper side of the rear cover plate body 62. The brim structure 52 is sleeved on the rear cover top 61. First side folds 64 are provided on both sides of the rear cover plate body 62. The first side folds 64 are connected to the box body sidewalls 11. 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 air flow channel 10. The provision of the rear cover plate 6 can effectively protect the first gap 8 and the second gap, preventing rainwater from entering the electric control box through the first gap 8 and the second gap, significantly improving the waterproof performance of the electric control box.

[0062] As one of the preferred embodiments, Figure 16 、 Figure 20 、 Figure 23 As shown, a plurality of exhaust ports 621 are provided on the rear cover body 62, and a lower sealing plate 65 is provided on the lower side of the rear cover body 62. The lower sealing plate 65 extends toward the rear plate 15 and is positioned in close contact with the rear plate 15. When the lower sealing plate 65 and the exhaust ports 621 are not provided, the gas after heat exchange will all be discharged from the lower opening of the rear cover 6. On the one hand, the concentrated exhaust gas is not conducive to dispersed heat dissipation. On the other hand, the exhaust of hot air through a single opening will cause an abnormal temperature rise near the opening, which can easily affect the normal operation of the unit. Therefore, by providing the lower sealing plate 65 and the exhaust ports 621, the gas in the airflow channel 10 is discharged from the exhaust ports 621 in a dispersed manner, making the exhaust more evenly dispersed and significantly improving the heat dissipation effect.

[0063] In one of the optional embodiments, Figure 20 As shown, the opening angle of the exhaust port 621 is downward. This arrangement can prevent rainwater from penetrating into the electric control box through the exhaust port 621, thereby ensuring the waterproof effect of the electric control box.

[0064] Better, such as Figure 16 、 Figure 23As 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 electric control box, condensation water is easily formed along the inner and outer walls of the rear cover body 62. Due to the presence of the lower sealing plate 65, the condensation water formed on the inner wall of the rear cover body 62 cannot be smoothly drained. Long-term retention will not only produce odor, but also easily cause the electric control box to rust, shortening its service life. The provision of the second through holes 651 allows the condensation water to be smoothly drained, keeping the airflow channel 10 in a dry state at all times. At the same time, the second through holes 651 can also discharge some of the heat-exchanged gas, thereby increasing the exhaust efficiency of the rear cover 6.

[0065] As one of the preferred embodiments, Figure 15 、 Figure 16 、 Figure 23 As shown, the rear cover 6 also includes a second folded edge 63, which is disposed on the underside of the rear cover body 62. The front side of the second folded edge 63 is in contact with the rear panel 15 and extends away from the rear panel 15. A second upward-facing flange is disposed at the trailing end of the second folded edge 63. The second folded edge 63 is used to collect condensed water or rainwater from the rear cover body 62 to prevent it from falling onto the components below. The provision of the second flange ensures that the collected water can only be discharged through the two ends of the second folded edge 63, facilitating the provision of a unified drainage structure on the underside.

[0066] As an embodiment of the present invention, Figure 25 As shown, a radiator 9 is further provided on the rear panel 15. The radiator 9 is provided on the lower side of the second folded edge 63. 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 the two ends of the second folded edge 63 in the left-right direction. The length of the radiator 9 also refers to the distance between the two ends of the radiator 9 in the left-right direction. This arrangement prevents water discharged from the two ends of the second folded edge 63 from dripping onto the radiator 9, thereby effectively protecting the radiator 9.

[0067] As an optional embodiment, Figure 2 、 Figure 3 As shown, a top fold 113 extending toward the interior of the electric control box body 1 is provided at the top of the box body side wall 11. The provision of the top fold 113 can increase the contact area between the box body side wall 11 and the top cover 5, thereby improving its supporting strength.

[0068] It should be noted that, in this embodiment, the top cover 5 is mounted on the top of the rear cover 6, the electric control box body 1, and the box cover 2, and the brim structure 52 covers the top of the rear cover 6, the electric control box body 1, and the box cover 2, and covers the gaps at their connections, thereby greatly improving the waterproof performance of the electric control box.

[0069] In some optional embodiments, Figure 20 As shown, the rear cover body 62, the lower cover plate 65, and the second folding edge 63 are integrally formed. At the same time, one side of the lower cover plate 65 and the second folding edge 63 is in contact with the rear plate 15, which simplifies the production and assembly steps of the rear cover 6.

[0070] In the prior art, components such as the driver board, filter board, and reactor are typically fixed within the electrical control box, while a main control board and terminal board are mounted on a separate electrical control mounting plate 4 to facilitate external power connections. The electrical control mounting plate 4 is typically located within the electrical control box near the box cover 2, shielding the driver board, filter board, reactor, and other components within the box. The electrical control mounting plate 4 is secured to the electrical control box body 1 with screws. If components within the electrical control box are damaged, the entire electrical control mounting plate 4 must be removed before repairs can be performed. This makes disassembly and assembly complex and significantly impacts repair efficiency.

[0071] In this embodiment, if Figure 7-12 As shown, the electric control mounting plate 4 is included. A rotating connection structure is provided between the electric control box body 1 and the electric control mounting plate 4. The electric control mounting plate 4 is rotatably connected to the electric control box body 1 via the rotating connection structure. The rotatable connection between the electric control mounting plate 4 and the electric control box body 1 allows the electric control mounting plate 4 to be rotated and opened relative to the electric control box body 1. Therefore, when it is necessary to repair or replace the components inside the electric control box, there is no need to completely remove the electric control mounting plate 4. By rotating it open, the internal components can be exposed, which facilitates repair and replacement. This reduces the time required to disassemble and assemble the electric control mounting plate 4 and also facilitates the installation, repair, and replacement of the internal components of the electric control box.

[0072] In one embodiment, Figure 11 、 Figure 12 As shown, the electric control box body 1 includes a box body side wall 11, the electric control mounting plate 4 includes a mounting plate side wall 41, and the rotating connection structure is arranged between the box body side wall 11 and the mounting plate side wall 41. Generally, the electric control mounting plate 4 and the box body side wall 11 are arranged perpendicularly. If the rotating connection structure is directly arranged between the two, it will affect the installation space of the main control board and the terminal board on the electric control mounting plate 4. The provision of the mounting plate side wall 41 allows the rotating connection structure to be arranged between the two connection surfaces, thereby providing sufficient installation space for them, while not affecting the installation of the main control board and the terminal board on the electric control mounting plate 4.

[0073] As an embodiment of the present invention, Figure 11 、 Figure 12 As shown, the rotational connection structure includes a connection slot and a connection shaft 114. The connection shaft 114 extends into the connection slot to form a rotational connection. In this arrangement, the connection shaft 114 serves as the rotational axis of the electrical control mounting plate 4. When components within the electrical control box require repair or replacement, the electrical control mounting plate 4 is simply rotated open around the connection shaft 114, exposing the components behind it. This is a simple and convenient method. It should be understood that the connection slot can be provided on the electrical control box body 1 or on the mounting plate sidewall 41, and the connection shaft 114 can be correspondingly provided on the mounting plate sidewall 41 or on the electrical control box body 1.

[0074] As one of the preferred embodiments, Figure 11 、 Figure 12 As shown, the connecting groove is provided on the mounting plate side wall 41, and the connecting shaft 114 is provided on the electric control box body 1. It should be understood that when the connecting groove is provided on the electric control box body 1, a through hole will appear on the box body side wall 11, which will easily lead to rainwater intrusion and is not conducive to the waterproofing of the electric control box. Providing the connecting groove on the mounting plate side wall 41 and the connecting shaft 114 on the box body side wall 11 can effectively avoid the above problem and ensure the waterproofing of the electric control box.

[0075] Specifically in this embodiment, Figure 3 As shown, a first recessed platform 111 is provided on the side wall 11 of the box body, a first through-hole 112 is provided in the first recessed platform 111, and 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, which 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 toward the interior of the electric control box, and is used to cooperate with the connecting groove to realize the rotational connection between the electric control mounting plate 4 and the electric control box body 1.

[0076] In some optional embodiments, Figure 7As shown, the connecting groove includes a first opening groove and a second opening groove. The open end of the second opening groove is connected to the rear end of the first opening groove. The extension direction of the second opening groove forms an angle with the extension direction of the first opening groove. The open end of the first opening groove forms the entrance of the connecting shaft 114. In this embodiment, the first opening groove is used to position the electrical control mounting plate 4 when fixedly connected to the electrical control box body 1, and the second opening groove is used to prevent the electrical control mounting plate 4 from falling off the electrical control box body 1 when it is rotated and opened relative to the electrical control box body 1. Specifically, the connecting shaft 114 enters from the open end of the first opening slot and can move relatively in the first opening slot and the second opening slot. In this arrangement, the connecting shaft 114 enters from the open end of the first opening slot, which can realize the rapid assembly of the electric control installation plate 4. At the same time, through the connection arrangement of the open end of the second opening slot and the tail end of the first opening slot, the connecting shaft 114 moves in different directions after entering the second opening slot. This arrangement can move the connecting shaft 114 to the second opening slot when rotating to open, so that the electric control installation plate 4 is not easy to fall out of the connecting slot when rotating to open, thereby avoiding the electric control installation plate 4 from being separated from the electric control box body 1 when rotating to open, to ensure that the electric control installation plate 4 can be quickly restored after the components in the electric control box are repaired.

[0077] In some optional embodiments, Figure 7 As shown, the first opening slot is an open vertical slot 411, and the second opening slot corresponds to an open horizontal slot 412. This arrangement makes the extension directions of the first opening slot and the second opening slot distinctly different, which helps to select the moving direction of the electric control mounting plate 4 during component maintenance. The electric control mounting plate 4 can be moved along the second opening slot and then rotated to open, effectively preventing the electric control mounting plate 4 from being disengaged from the electric control box body 1.

[0078] In one optional embodiment, Figure 7 As shown, the open vertical slot 411 is arranged on the lower side of the open transverse slot 412. It should be understood that if the open vertical slot 411 is arranged on the upper side of the open transverse slot 412, then when the electric control mounting plate 4 is fixedly connected, it is necessary to manually support the electric control mounting plate 4 so that its fixing structure can be installed on it. This arrangement helps to support the connecting shaft 114 at the connection between the open transverse slot 412 and the open vertical slot 411, avoiding the problem of manual support by the assembler and improving the assembly efficiency of the product.

[0079] As one of the preferred embodiments, Figure 7As shown, the angle between the vertical opening slot 411 and the horizontal opening slot 412 is between 75° and 85°. This arrangement allows the vertical opening slot 411 to be positioned below the horizontal opening slot 412, creating a high point at the tail end of the first opening slot and the open end of the second opening slot, facilitating rapid positioning of the electrical control mounting plate 4 and the electrical control box body 1 when they are fixedly connected. Preferably, the angle is 80°.

[0080] In an optional embodiment, a folding structure is provided on the front side of the box body side wall 11, a fourth fixing structure is provided on the folding structure, and a fifth fixing structure is provided on the mounting plate side wall 41. The fourth fixing structure cooperates with the fifth fixing structure for fixed connection. It should be understood that the rotational connection structure is primarily used for the rotational connection between the electrical control mounting plate 4 and the electrical control box body 1. Therefore, additional fixed connection structures are required to prevent the electrical control mounting plate 4 from moving within the electrical control box and ensure the installation stability of the electrical control mounting plate 4.

[0081] Specifically in this embodiment, Figure 3 、 Figure 7 、 Figure 8 As shown, the fourth fixing structure includes a second sunken platform 141 and a second connecting hole 1411 provided on the second sunken platform 141, and the fifth fixing structure includes a fifth folded edge 413 provided on the side wall 41 of the mounting plate, and a fifth connecting hole 4131 provided on the fifth folded edge 413. The second sunken platform 141 is provided in cooperation with the fifth folded edge 413, and the second connecting hole 1411 is connected in cooperation with the fifth connecting hole 4131. 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 electric control mounting plate 4 and the electric control box body 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 sink 141 cooperates with the fifth fold 413, and the second connecting hole 1411 cooperates with the fifth connecting hole 4131. This setting can utilize the supporting effect of the connecting shaft 114 to achieve alignment between the fourth fixing structure and the fifth fixing structure, making its fixing process simple and quick. At the same time, when it is necessary to open the electric control installation board 4, the screw is unscrewed, and the electric control installation board 4 is moved so that the connecting shaft 114 enters the second open groove. At this time, the electric control installation board 4 will not fall off when it is rotated. The connecting shaft 114 is limitedly abutted against the tail end face of the second open groove. It should be understood that when the second open groove is an open transverse groove 412, the tail end face is the transverse groove tail face 4121. The setting of the second sink 141 can ensure that the box cover 2 cooperates with the second fold 14 when it is installed, and will not be bulged due to the presence of the fifth fold 413, thereby ensuring the waterproof effect of the electric control box.

[0082] As a preferred embodiment, Figure 8 、 Figure 12 As shown, a notch 414 is provided on the lower side of the fifth fold 413. The notch 414 is used to prevent the fifth fold 413 from interfering with the bottom plate 17 of the electric control box body 1. Figure 12 As shown, the rotation radius of the electric control installation board 4 can be effectively increased, thereby completely exposing the components on its rear side, which is beneficial to the maintenance and replacement of components.

[0083] like Figure 10 When the electric control installation board 4 needs to be opened, first unscrew the screw in the fifth connecting hole 4131, then pull the electric control installation board 4 outward to allow the connecting shaft 114 to enter the open transverse groove 412, and then rotate the electric control installation board 4 downward to open it, so that the components on its rear side can be repaired or replaced.

[0084] like Figures 1-6 、 Figure 26 As shown, it also includes a box cover 2, and a folding structure with a groove 13 is provided on the side wall 11 of the box body. The groove 13 is recessed in the direction away from the box cover 2, and a third folding edge 22 is provided on the box cover 2. The groove 13 is assembled with the third folding edge 22. In the prior art, most electronic control boxes utilize a flat surface to abut against the control box body 1 and the cover 2. This easily allows rainwater to seep into the control box through gaps in the surface, affecting the operation of the electronic control components within the control box. In this embodiment, the control box body 1 includes two side walls 11. Each side wall 11, located near the cover 2, is provided with a folded structure having a groove 13. The groove 13 is assembled with a third folded edge 22. Due to the distance difference between the first and second side walls 133, 134 of the groove 13 and the folded surface of the folded structure in the front-to-back direction, rainwater cannot enter the control box and can be drained along the groove 13, thereby effectively improving the waterproofing of the control box. It should be understood that the third folded edge 22 extends in the front-to-back direction toward the control box body 1. During assembly, the bottom surface 131 of the groove 13 abuts against the end of the third folded edge 22, thereby forming a good sealing structure and further improving the waterproofing of the control box. Preferably, the second side wall 134 of the groove 13 close to the box body side wall 11 is arranged to fit the inner surface of the third folded edge 22, which can more effectively prevent rainwater from entering from the side into the interior of the electric control box.

[0085] As one of the preferred embodiments, Figure 1 、 Figure 2As shown, the folding structure further includes at least a first folding edge 12, which is arranged on the side of the groove 13 away from the box body side wall 11, and a first fixing structure is provided on the first folding edge 12, and the first fixing structure is used for fixing the electric control box in the unit. In an optional embodiment, the unit is an air conditioner outdoor unit, and the first fixing structure can be fixedly connected to the unit shell and / or the device inside the unit, the unit shell includes a front panel and / or a unit side panel 3, a fixed folding edge 31 is provided on the unit side panel 3, and a seventh connection hole (not shown in the figure) is provided on the fixed folding edge 31, and the device inside the unit can include a condenser, a side plate (not shown in the figure) is provided on the condenser, and an eighth connection hole (not shown in the figure) is provided on the side plate, and the first connection hole 121 cooperates with the seventh connection hole and / or the eighth connection hole to achieve a fixed connection between the fixed folding edge 31 and / or the side plate and the first folding edge 12. This arrangement eliminates the need for a fixing plate when securing the electrical control box, significantly reducing the number of parts required for securing the electrical control box body 1 and improving product production efficiency. In one embodiment, the first fixing structure is a first connecting hole 121, through which screws are passed to secure the electrical control box. In an optional embodiment, the first folded edge 12 is synchronously secured to the side panel of the air conditioner outdoor unit and the condenser side panel, thereby improving the installation stability of the electrical control box, reducing the number of parts required for securing the electrical control box assembly, reducing production costs, and improving production efficiency.

[0086] In this embodiment, if Figure 5 、 Figure 18 As shown, the lower end of the box cover 2 is lower than the bottom plate 17 of the electric control box body 1, and a first flange 25 is provided at the lower end of the box cover 2, the first flange 25 extending toward the direction of the electric control box body 1, and a first flange extending upward is provided at the tail end of the extension direction of the first flange 25. In the prior art, the air inlet of the electric control box is often arranged on the bottom plate 17 of the electric control box body 1. If the lower end of the box cover 2 is flush with or higher than the bottom plate 17, the rainwater flowing down along the front side of the box cover 2 will easily flow to the lower surface of the bottom plate 17, which will cause the rainwater to be easily brought into the electric control box when the air enters. The setting of the first folded edge 25 can prevent this part of the rainwater from flowing to the bottom plate 17, thereby improving the waterproof effect of the electric control box. In addition, the amount of water flowing downward along the groove 13 is large and it is easier to enter the area of the bottom plate 17. The setting of the first folded edge 25 can play a role in collecting water, further improving the waterproof effect of the electric control box. At the same time, the setting of the first folded edge makes it possible for the water entering the first folded edge 25 to flow out only from both sides, which is conducive to simplifying the drainage structure on the base of the casing.

[0087] As one of the optional embodiments, Figure 2 、 Figure 5 As shown, a snap-fit structure is provided between the groove 13 and the box cover 2. The snap-fit structure is used to quickly limit the connection between the box cover 2 and the electric control box body 1, thereby facilitating the subsequent fixed connection between the box cover 2 and the electric control box body 1.

[0088] In this embodiment, if Figure 2 、 Figure 5 As shown, the snap-fit structure includes a snap-fit hole 132 and a snap-fit hook 21, and the snap-fit hook 21 extends into the snap-fit hole 132 to form a snap-fit. The structures of the snap-fit hook 21 and the snap-fit hole 132 are simple, easy to produce, and have a good limiting effect. It should be understood that there is more than one snap-fit structure in order to obtain a better limiting effect. The snap-fit hole 132 can be entirely set on the groove 13. In this case, the snap-fit hook 21 is correspondingly set on the box cover 2. The snap-fit hole 132 can also be entirely set on the box cover 2. In this case, the snap-fit hook 21 is correspondingly set on the groove 13. The snap-fit hole 132 can be partially set on the groove 13 and partially set on the box cover 2. The snap-fit hook 21 and the snap-fit hole 132 can be correspondingly set on the box cover 2 or the groove 13. It should be noted that the latch hole 132 and / or the latch 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 achieved.

[0089] As a preferred embodiment, Figure 2 、 Figure 5 As shown, the latch hole 132 is provided on the bottom surface 131 of the groove 13, and the latch hook 21 is provided on the box cover 2. It should be understood that when the latch hole 132 is provided on the box cover 2, rainwater on the surface of the box cover 2 is likely to penetrate through the fitting gap of the latch structure and penetrate into the interior of the electric control box along the inner surface of the box cover 2, thereby affecting the waterproof effect of the electric control box. This arrangement makes the fitting and assembly of the latch hook 21 and the latch hole 132 simpler and faster. At the same time, rainwater that penetrates along the fitting gap of the latch structure can only enter the groove 13 and be discharged along the groove 13, further improving the waterproof effect of the electric control box.

[0090] As another embodiment, Figure 1 、 Figure 6As shown, the folding structure also includes a second folding edge 14, which is provided on the side of the groove 13 close to the box body side wall 11. A second fixing structure is provided on the second folding edge 14, and a third fixing structure is provided on the box cover 2. The second fixing structure and the third fixing structure are provided in conjunction with each other to securely connect the electric control box body 1 and the box cover 2. As one of the optional embodiments of this invention, 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 securely connected by screws. It should be understood that by limiting the position of the electric control box body 1 and the box cover 2 by the snap-fit structure before securely connecting them, the step of securing them during secure connection can be omitted, thereby speeding up the assembly speed of the secure connection and improving production efficiency.

[0091] Specifically in this embodiment, Figure 6 、 Figure 10 As shown, the top cover 5 is provided on the upper end of the electric control box body 1. A brim structure 52 is provided circumferentially on the top cover 5. The brim structure 52 is sleeved on the upper end of the box cover 2. The arrangement of the brim structure 52 allows the connection seam between the box cover 2 and the top cover 5 to face downward. Compared with the prior art solution in which the connection seam faces upward, this more effectively prevents rainwater from seeping through the connection seam and enhances the waterproof performance of the electric control box.

[0092] In some optional embodiments, Figure 6 As shown, fourth folded edges 24 are provided near the upper ends on both sides of the box cover 2 in the left and right directions. The fourth folded edges 24 are bent toward the electrical control box body 1 and are inclined in the left and right directions. The end of the fourth folded edge 24 near the electrical control box body 1 is higher than the end near the groove 13. This arrangement allows rainwater that enters through the brim structure 52 to flow along the inclined surface of the fourth folded edge 24 into the groove 13, thereby preventing it from entering the interior of the electrical control box, effectively improving the waterproof performance of the electrical control box.

[0093] As one example, Figure 5 As shown, the hook 21 is provided on the box cover 2, and the opening of the hook 21 is upward. It should be understood that in the present application, due to the provision of the brim structure 52 on the top cover 5, the box cover 2 needs to be assembled from bottom to top. If the opening of the hook 21 is downward, the box cover 2 and the brim structure 52 will interfere with each other and cannot be assembled. This arrangement allows the hook 21 to be installed from bottom to top when it is limited by the engagement with the locking hole 132, which is consistent with the assembly direction of the box cover 2 and the brim structure 52, thereby facilitating the smooth assembly of the box cover 2.

[0094] As an optional embodiment, Figure 4As shown, several reinforcing profiles 122 are provided at the junction of the first folded edge 12 and the groove 13, and / or at the junction of the second folded edge 14 and the groove 13. The reinforcing profiles 122 are used to enhance the strength of the folding structure. Because the folding structure is provided with a large number of connecting structures, the provision of the reinforcing profiles 122 can effectively prevent these connecting structures from causing deformation of the folding structure, thereby avoiding affecting the waterproof performance of the electrical control box. The reinforcing profiles 122 are convex or concave structures, and preferably, the reinforcing profiles 122 are V-shaped convex or concave structures.

[0095] Example 2

[0096] This embodiment discloses an air conditioner, which includes the waterproof heat dissipation structure of the electric control box described in Example 1.

[0097] The advantages of the air conditioner and the waterproof heat dissipation structure of the electric control box described in Example 1 over the prior art are the same and will not be repeated here.

[0098] In another embodiment of the present invention, Figure 19 、 Figure 20 As shown, the air conditioner includes a crossbeam 32, and a connecting plate 7 is provided on the upper side of the top cover 5. The connecting plate 7 is assembled with the crossbeam 32. In some optional embodiments, the connecting plate 7 is fixedly connected to the crossbeam 32 in the unit. The provision of the connecting plate 7 can further enhance the assembly stability of the electric 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.

[0099] In one embodiment, 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. The connecting plate body 71 is also provided with a sixth connecting hole 73, which is used for fixed connection with the crossbeam 32. The third folded edge 72 is used to hook and position with the crossbeam 32 so that the sixth connecting hole 73 is aligned and fixedly connected.

[0100] In other optional embodiments, such as Figure 17As shown, the connecting plate 7 further includes a horizontal hem 75, which is fixedly connected to the top cover 5. Second side hems 74 are provided at both ends of the connecting plate 7 in the left and right directions. The second side hems 74 at the lower portion of the horizontal hems 75 are disposed in abutment with the box body sidewalls 11. The provision of the horizontal hems 75 increases the connection area between the connecting plate 7 and the top cover 5, thereby helping to increase the strength of the connection and enhance the stability of the connection between the electrical control box and the unit. The provision of the second side hems 74 can cover the gap at the connection between the horizontal hem 75 and the top cover 5, preventing rainwater from accumulating in the gap and ensuring the waterproof performance of the electrical control box.

[0101] In this embodiment, the top cover 5 is integrally formed with one or two of the rear cover plate 6 and the connecting plate 7, or the top cover 5, the rear cover plate 6 and the connecting plate 7 are separately formed. The integral formation of the top cover 5, the rear cover plate 6 and the connecting plate 7 can reduce the number of parts and improve the assembly efficiency of the electric control box. The separate formation of the top cover 5, the rear cover plate 6 and the connecting plate 7 can greatly reduce the difficulty of mold production and manufacturing, and can also significantly reduce the mold opening cost. In some optional embodiments, when the top cover 5, the rear cover plate 6 and the connecting plate 7 are separately formed, the top cover 5 and the rear cover plate 6, and the top cover 5 and the connecting plate 7 can be fixedly connected by welding or riveting, which will not be repeated here.

[0102] It should be noted that the air conditioner also includes conventional components of the air conditioner such as a compressor, an indoor heat exchanger, and an outdoor heat exchanger. Their specific structures and connection relationships can refer to existing technical solutions and will not be limited or elaborated on here.
