Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a housing and an air conditioner. Background Technology

[0002] During the operation of an air conditioner, if a short circuit occurs in the components inside the control box, causing the temperature inside the control box to rise sharply and the gas to expand, it can easily cause the control box cover to separate and then hit the frame or panel, resulting in deformation or even cracking of the frame or panel. Flames will also burst out and burn, increasing the risk of fire. Utility Model Content

[0003] The main purpose of this utility model is to propose a housing and an air conditioner that increases the structural strength of the parts of the air conditioner housing that are subjected to impact, thereby reducing the risk of fire caused by flames escaping from the electrical control box.

[0004] To achieve the above objectives, the housing proposed in this utility model is applied to an air conditioner, the housing comprising:

[0005] The main body includes side walls and a support plate connected to the side walls. The support plate is positioned opposite the fireproof plate of the electrical control box when the housing is mounted on the air conditioner. The support plate is provided with a reinforcing structure connected to the side walls.

[0006] A limiting protrusion is provided on the support plate to correspond with the fireproof plate of the electrical control box, thereby restricting the movement of the fireproof plate toward the support plate.

[0007] In one embodiment, the reinforcing structure includes a main reinforcing rib and a plurality of first secondary reinforcing ribs. The main reinforcing rib is disposed on the support plate and extends parallel to the adjacent sidewall. The first secondary reinforcing ribs are distributed along the extension direction of the main reinforcing rib and are connected between the main reinforcing rib and the sidewall.

[0008] In one embodiment, the height of the first reinforcing secondary rib at the connection point with the sidewall is greater than the protrusion height of the reinforcing main rib.

[0009] In one embodiment, the distance between the reinforcing main rib and the limiting protrusion is greater than the distance between the reinforcing main rib and the sidewall.

[0010] In one embodiment, the support plate has a reinforcing protrusion on its side where it intersects the sidewall, and the end of the reinforcing main rib is connected to the reinforcing protrusion.

[0011] In one embodiment, the reinforcing structure further includes a plurality of second reinforcing ribs, which are distributed around the periphery where the limiting protrusion connects to the support plate.

[0012] In one embodiment, on the side of the limiting protrusion opposite to the main reinforcing rib, the second reinforcing secondary rib is connected between the limiting protrusion and the main reinforcing rib.

[0013] In one embodiment, on the side of the limiting protrusion away from the main reinforcing rib, the edge of the support plate is provided with a reinforcing protrusion, and the second reinforcing secondary rib is connected between the limiting protrusion and the reinforcing protrusion.

[0014] In one embodiment, the limiting protrusion and the support plate are integrally formed.

[0015] In one embodiment, the main body is configured as the face frame or panel of the air conditioner.

[0016] In one embodiment, the limiting protrusion includes a support column connected to the support plate and a limiting column away from the support plate. The support column is hollow and extends through the main body on the side away from the limiting column, and / or the limiting column is hollow and extends through the end away from the support column.

[0017] This utility model also proposes an air conditioner, which includes an electrical control box and a housing as described above, wherein the electrical control box is provided with a fireproof plate.

[0018] In one embodiment, the fireproof plate has a groove on the side opposite to the limiting protrusion, and the gap between the limiting protrusion and the bottom of the groove is between 2mm and 5mm.

[0019] In one embodiment, the electrical control box includes a box body with an open side, and the fireproof plate includes a fireproof cover plate. The edge of the fireproof cover plate is provided with a limiting flange. The fireproof cover plate is provided corresponding to the open side of the box body and abuts against the side of the box body through the limiting flange. The distance between the edge of the limiting flange and the open side of the box body is greater than the distance between the limiting protrusion and the fireproof cover plate.

[0020] In one embodiment, the box body includes an inner box portion and an outer box portion, and the fireproof board further includes a protective inner plate. The openings of the inner box portion and the outer box portion are arranged on the same side. The protective inner plate is fastened to the opening side of the inner box portion. The outer box portion covers the inner box portion. The fireproof cover is located on the side of the protective inner plate away from the inner box portion and covers the opening side of the outer box portion. The limiting flange abuts against the outer side wall of the outer box portion.

[0021] The technical solution of this utility model involves setting a limiting protrusion on the support plate of the fireproof plate of the main body relative to the electrical control box, and setting a reinforcing structure on the support plate. The reinforcing structure can be connected to the side wall of the main body together with the support plate, thereby strengthening the integrity of the side wall of the main body and the support plate, as well as the structural strength of the main body. Thus, during the process of combustion inside the electrical control box leading to the fireproof plate being pushed up, the limiting protrusion on the support plate will abut against the fireproof plate to restrict its movement. The support plate and its reinforcing structure effectively transfer the impact force of the fireproof plate on the limiting protrusion to the side wall of the main body. This achieves the goal of using the structurally strong and integral main body to resist the impact of the fireproof plate, reducing the risk of shell damage and ensuring the limiting protrusion's limiting effect on the fireproof plate. This ensures that the fireproof plate can be stably maintained in a good protective position, thereby reducing the probability of flames inside the electrical control box escaping due to the protective plate detaching, and thus reducing the risk of fire.

[0039] This utility model proposes a shell.

[0040] Please refer to Figure 1 , Figure 2 and Figure 5 In one embodiment of this utility model, the housing is applied to an air conditioner, and the housing includes:

[0041] The main body 100 includes a side wall 120 and a support plate 110 connecting the side wall 120. The support plate 110 is positioned opposite the fireproof plate 310 of the electrical control box 300 when the housing is installed on the air conditioner. The support plate 110 is provided with a reinforcing structure 130, which is connected to the side wall 120.

[0042] A limiting protrusion 200 is provided on the support plate 110 to correspond to the fireproof plate 310 of the electrical control box 300, so as to restrict the movement of the fireproof plate 310 toward the support plate 110.

[0043] The technical solution of this utility model is to provide a limiting protrusion 200 on the support plate 110 of the fireproof plate 310 of the main body 100 relative to the electrical control box 300, and to provide a reinforcing structure 130 on the support plate 110. The reinforcing structure 130 can be connected to the side wall 120 on the main body 100 together with the support plate 110, thereby strengthening the integrity of the side wall 120 and the support plate 110 of the main body 100 and the structural strength of the main body 100. Thus, during the process of combustion occurring inside the electrical control box 300 and the fireproof plate 310 being lifted, the limiting protrusion 200 on the support plate 110 will abut against the fireproof plate 310 to restrict its movement. The support plate 110 and its reinforcing structure 130 effectively transfer the impact force of the fireproof plate 310 on the limiting protrusion 200 to the side wall 120 of the main body 100. This allows the main body 100, with its superior structural strength and integrity, to withstand the impact of the fireproof plate 310, reducing the risk of shell damage. This ensures that the limiting protrusion 200 effectively limits the fireproof plate 310, ensuring that the fireproof plate 310 can be stably maintained in a better protective position. This reduces the probability of flames inside the electrical control box 300 escaping due to the protective plate falling off, thereby reducing the risk of a fire.

[0044] The reinforcing structure 130 includes a portion connected to the support plate 110 and a portion connected to the side wall 120. The side wall 120 of the main body 100 is connected to at least one edge of the support plate 110 and is set at an angle to the support plate 110, such as the side wall 120 being perpendicular to the support plate 110 or connected at an obtuse angle. The reinforcing structure 130 can be connected to the support plate 110 where the limiting protrusion 200 is provided, or it can be at a certain distance from the limiting protrusion 200, but it at least connects the edge where the support plate 110 and the side wall 120 are connected. This improves the ability of the support plate 110 to resist the impact of the limiting protrusion 200, and also enhances the efficiency of the support plate 110 in distributing the impact force to the side wall 120, so that the main body 100 as a whole can more evenly bear the impact of the fireproof board 310. It should be noted that the reinforcing structure 130 is located on the side of the support plate 110 facing the fireproof board 310. It can be configured as a reinforcing rib, such as a mesh or multiple parallel ribs, or it can be configured to give the surface of the support plate 110 a textured surface. It can also be a reinforcing plate or rib embedded within the support plate 110 and partially connected to the side wall 120. Furthermore, the reinforcing structure 130 is adapted to the distribution position of the side wall 120 around the support plate 110. The reinforcing structure 130 can be distributed throughout the support plate 110, or it can be located in the area between the corresponding limiting protrusion 200 and the side wall 120 of the support plate 110.

[0045] In one embodiment, please refer to Figure 5 and Figure 7The main body 100 is configured as the face frame or panel of an air conditioner. Thus, when assembling the face frame or panel of the air conditioner, the lower protrusion can be simultaneously aligned with the fireproof plate 310 without the need for a separate limiting protrusion 200, improving assembly efficiency. In this embodiment, the main body 100 is configured as the face frame, and the side wall 120 is the side wall 120 of the face frame. Regarding the connection between the limiting protrusion 200 and the support plate 110, in this embodiment, the limiting protrusion 200 and the support plate 110 are integrally formed, making relative displacement between them difficult. When the limiting protrusion 200 itself is impacted by the fireproof plate 310, the impact force can be effectively and promptly dispersed into the main body 100, preventing displacement of the limiting protrusion 200 and thus avoiding increased impact force on the main body 100. This ensures the stability of the shell's limiting and supporting function against the fireproof plate 310. Of course, in other embodiments, the main body 100 can also be set independently, and the face frame or panel can be assembled after installation; or, the limiting protrusion 200 and the support plate 110 can be formed separately and then connected by welding or screwing.

[0046] In one embodiment, please refer to Figure 2 and Figure 4 The reinforcing structure 130 includes a main reinforcing rib 131 and multiple first secondary reinforcing ribs 132. The main reinforcing rib 131 is disposed on the support plate 110 and extends parallel to the adjacent sidewall 120. The first secondary reinforcing ribs 132 are distributed along the extension direction of the main reinforcing rib 131 and connected between the main reinforcing rib 131 and the sidewall 120. The main reinforcing rib 131 can concentrate the internal stress at any point of the support plate 110 adjacent to the sidewall 120, so that the impact force transmitted from the limiting protrusion 200 to the support plate 110 can be re-evented at the main reinforcing rib 131, reducing the probability of excessive stress at a single point between the support plate 110 and the sidewall 120, thereby reducing the risk of cracking or other damage at the connection between the support plate 110 and the sidewall 120. Furthermore, multiple first reinforcing secondary ribs 132 are evenly distributed along the direction of the reinforcing main rib 131 and connect the main rib to the side wall 120. This effectively forms a stable load-bearing structure with the reinforcing main rib 131, the support plate 110, and the side wall 120. This helps to rationally transfer the pressure from the support plate 110 to the relatively more stable structural parts such as the side wall 120, thereby avoiding stress concentration at a certain point and structural failure. Thus, when a short circuit occurs and a fire breaks out in the internal components of the electrical control box 300, a momentary pressure shock wave may be generated, causing the fireproof plate 310 to be pushed open or even ejected. The main body 100, reinforced by the main rib 131 and the first reinforcing secondary ribs 132, has good impact resistance, allowing the shell to withstand higher internal pressure in a short time, delaying or even preventing the lid from flying out, thereby reducing the risk of fire. Of course, in other embodiments, the reinforcing structure 130 can also be set as a mesh of reinforcing ribs, distributed throughout the support plate 110 and connected to the side wall 120.

[0047] Furthermore, in this embodiment, please refer to Figures 2 to 4 The height of the first reinforcing secondary rib 132 at the connection point with the side wall 120 is greater than the protrusion height of the reinforcing main rib 131. It can be understood that by making the height of the first reinforcing secondary rib 132 at the connection point with the side wall 120 higher than the protrusion height of the reinforcing main rib 131, a stepped reinforcing structure 130 can be formed between the support plate 110 and the side wall 120. This more effectively disperses the impact force to the side wall 120 when the support plate 110 is under stress, preventing excessive concentration of impact force on the support plate 110 and reducing the risk of deformation and breakage. Meanwhile, the height of the first reinforcing secondary rib 132 at the side wall 120 is greater than the protrusion height of the reinforcing main rib 131. From the reinforcing main rib 131 to the side wall 120, the height of the first reinforcing secondary rib 132 gradually increases, thus providing stronger support along the extension direction of the reinforcing main rib 131. This makes the reinforced structure 130 more stable, thereby enhancing the bending strength of the support plate 110 and its connection with the side wall 120. Furthermore, compared to the first reinforcing secondary rib 132 being a single piece, the arrangement of the first reinforcing secondary rib 132 and the reinforcing main rib 131 in this embodiment not only facilitates the forming of the main body 100 but also prevents deformation and breakage at the connection between the reinforced structure 130 and the support plate 110 and side wall 120. Of course, in other embodiments, the height of the first reinforcing secondary rib 132 at the side wall 120 can also be the same as the protrusion height of the reinforcing main rib 131.

[0048] In one embodiment, please refer to Figure 2 and Figure 4 The distance between the reinforcing main rib 131 and the limiting protrusion 200 is greater than the distance between the reinforcing main rib 131 and the side wall 120. This means that the reinforcing main rib 131 is positioned closer to the side wall 120 than the limiting protrusion 200, allowing it to concentrate the impact force from the limiting protrusion 200 distributed by the support plate 110 and quickly and evenly transfer it to the side wall 120. This reduces the dispersion of the impact force of the fireproof plate 310 on the side wall 120, promoting the use of the overall integrity of the main body 100 to resist the impact of the fireproof plate 310. Simultaneously, a larger distance between the limiting protrusion 200 and the reinforcing main rib 131 facilitates demolding of the shell. Of course, in other embodiments, the distance between the reinforcing main rib 131 and the limiting protrusion 200 can also be equal to its distance to the side wall 120, or secondary ribs can be provided on both sides of the reinforcing main rib 131, so that reinforcing ribs are provided between the limiting protrusion 200 and the side wall 120.

[0049] Regarding the connection structure of the reinforcing main rib 131, in one embodiment, please refer to... Figures 2 to 4A reinforcing protrusion 111 is provided on the side of the support plate 110 where it intersects with the side wall 120, and the end of the reinforcing main rib 131 is connected to the reinforcing protrusion 111. It should be noted that the side of the support plate 110 where it intersects with the side wall 120 typically intersects with the reinforcing main rib 131, with the reinforcing protrusion 111 located near the support plate 110 but not abutting against the edge of the side wall 120. Combined with the fact that the reinforcing main rib 131 is positioned near the side wall 120 relative to the limiting protrusion 200, the reinforcing protrusion 111 can also be partially connected to the side wall 120, so that the reinforcing main rib 131, the reinforcing protrusion 111, and the side wall 120 form a closed ring structure, thereby improving the connection stability between the support plate 110 and the side wall 120. Simultaneously, the reinforcing main rib 131 can also obtain support through the reinforcing protrusion 111 at its end, allowing the load borne by the reinforcing main rib 131 to be more smoothly transferred to the side wall 120, avoiding stress concentration and breakage due to weak connections. In this embodiment, one end of the reinforcing main rib 131 may have a reinforcing protrusion 111, while the other end has a wall structure similar to that of the side wall 120. Alternatively, both ends of the reinforcing main rib 131 may have reinforcing protrusions 111. Of course, in other embodiments, at least one of the first reinforcing secondary ribs 132 may be connected to the side wall 120 at the end of the reinforcing main rib 131.

[0050] Regarding the force transmission between the limiting protrusion 200 and the support plate 110, in one embodiment, please refer to... Figures 1 to 4 The reinforcing structure 130 also includes multiple second reinforcing ribs 133, which are distributed around the periphery where the limiting protrusion 200 connects to the support plate 110. The second reinforcing ribs 133 can limit the displacement or deformation of the limiting protrusion 200 under external force, ensuring that the limiting protrusion 200 remains in a predetermined position, thereby restricting the movement of the fireproof plate 310. Simultaneously, the second reinforcing ribs 133 also help to evenly distribute the pressure borne by the limiting protrusion 200 onto the support plate 110, preventing structural damage due to excessive local pressure on the support plate 110. The second reinforcing ribs 133, distributed around the periphery of the limiting protrusion 200, form a balanced support around the periphery of the limiting protrusion 200, reducing the risk of tilting of the limiting protrusion 200 and thus ensuring the stability of the limiting support of the limiting protrusion 200 on the fireproof plate 310, thereby reducing the probability of a fire caused by flames escaping from the electrical control box 300. Of course, in other embodiments, the end of the limiting protrusion 200 connected to the support plate 110 can be set as a flared part to increase the basic coverage area of ​​the limiting protrusion 200, thereby improving the stability of the limiting protrusion 200 and the structural stability of the support plate 110.

[0051] Furthermore, in this embodiment, please refer to Figure 3 and Figure 4On the side of the limiting protrusion 200 opposite to the main reinforcing rib 131, a second reinforcing rib 133 connects the limiting protrusion 200 and the main reinforcing rib 131. By setting the second reinforcing rib 133, a structurally stable force transmission path is created between the main reinforcing rib 131 and the limiting protrusion 200. This not only strengthens the limiting protrusion 200 itself but also improves its bonding force with the overall structure of the main body 100, reducing the risk of partial cracking and damage to the support plate 110 between the main reinforcing rib 131 and the limiting protrusion 200. Specifically, when high-pressure gas is generated inside the electrical control box 300 to attempt to move the fireproof plate 310, the second reinforcing rib 133, located between the limiting protrusion 200 and the main reinforcing rib 131, provides a transmission guide for the impact force, promoting the efficiency of dispersing the impact force to the side wall 120 through the reinforcing structure 130, and reducing the risk of damage to the support plate 110.

[0052] For the side of the limiting protrusion 200 that is away from the reinforcing main rib 131 or the side wall 120, in this embodiment, please continue to refer to... Figure 2 and Figure 4 On the side of the limiting protrusion 200 facing away from the reinforcing main rib 131, the edge of the support plate 110 is provided with a reinforcing protrusion 111, and a second reinforcing secondary rib 133 connects the limiting protrusion 200 and the reinforcing protrusion 111. Referring to the above description regarding the connection of the end of the reinforcing main rib 131 to the reinforcing protrusion 111, the arrangement of the reinforcing protrusion 111 in this embodiment is consistent with the above description and will not be repeated here. Thus, the two ends of the first reinforcing secondary rib 132 on the side of the limiting protrusion 200 facing away from the reinforcing main rib 131 can be connected to the limiting protrusion 200 and the reinforcing protrusion 111 respectively, which can enhance the boundary constraint conditions of the limiting protrusion 200 and prevent it from shifting or tilting. At the same time, the reinforcing protrusion 111 can locally thicken and strengthen the edge structure of the support plate 110, improving its load-bearing capacity and durability. Among them, the second reinforcing rib 133 forms an approximately triangular structural frame between the limiting protrusion 200 and the reinforcing protrusion 111, so as to effectively resist the complex loads such as bending and shearing that the limiting protrusion 200 is subjected to, and ensure the stability and reliability of the limiting support of the fireproof board 310.

[0053] Regarding the structural form of the limiting protrusion 200 itself, in one embodiment, please refer to... Figures 6 to 8The limiting protrusion 200 includes a support column 210 connected to the support plate 110 and a limiting column 220 away from the support plate 110; the support column 210 is hollow and is disposed through the side of the main body 100 away from the limiting column 220, or the limiting column 220 is hollow and is disposed through the end away from the support column 210, or both the support column 210 and the limiting column 220 are hollow and are disposed through the corresponding ends opposite to each other. It is understandable that the hollow end of the support column 210, which is connected to the support plate 110, penetrates through the support plate 110. This avoids excessive stress concentration at the connection between the support column 210 and the support plate 110, making the transition between the support plate 110 and the support column 210 less prone to deformation and breakage. Similarly, the limiting column 220 can also evenly transmit the impact force from the fireproof plate 310 to the support column 210 in the circumferential direction, and then evenly transmit it to the side wall 120 at the edge of the support plate 110 around the limiting protrusion 200. This disperses the impact force from the fireproof plate 310, reduces the risk of cracking and damage to the shell due to excessive stress concentration at a single point, and thus ensures the effectiveness and stability of the fireproof plate 310 in the shell. In addition, having both ends of the limiting protrusion 200 penetrate through the support plate 110 facilitates the integral molding of the limiting protrusion 200 and the support plate 110, making it easier to manufacture the mold for the shell. Of course, in other embodiments, a mesh internal support structure can also be provided inside the hollow part of the limiting protrusion 200.

[0054] This utility model also proposes an air conditioner, such as Figure 5 As shown, the air conditioner includes an electrical control box 300 and a housing as described above. The specific structure of the housing is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the electrical control box 300 is provided with a fireproof plate 310 as described above.

[0055] In one embodiment, please refer to Figures 6 to 8The fireproof plate 310 has a groove 314 on the side opposite the limiting protrusion 200, and the gap between the limiting protrusion 200 and the bottom of the groove 314 is between 2mm and 5mm. It can be understood that when the fireproof plate 310 contacts the limiting protrusion 200, the groove 314 and the end of the limiting protrusion 200 serve to reinforce and limit the movement, ensuring the stress stability between the limiting protrusion 200 and the fireproof plate 310. Furthermore, a gap of greater than or equal to 2mm and less than or equal to 5mm is reserved between the groove 314 and the limiting protrusion 200. During air conditioner operation, the internal fan or motor will inevitably vibrate; this gap prevents the limiting protrusion 200 and the fireproof plate 310 from colliding and generating noise. Combined with the reinforcing structure 130 on the housing, which limits the range of the gap, when the fireproof plate 310 is subjected to impact, the limiting protrusion 200 can quickly limit the fireproof plate 310 and withstand the large impact of the fireproof plate 310 on the limiting protrusion 200, thereby reducing the probability of the fireproof plate 310 detaching from the electrical control box 300, and thus reducing the possibility of flames escaping from the electrical control box 300 or burning other components. The gap between the limiting protrusion 200 and the bottom of the groove 314 can be 2mm, 3mm, 4mm, or 5mm. Of course, in other embodiments, the area of ​​the fireproof plate 310 relative to the limiting protrusion 200 can also be flat, and the gap between the fireproof plate 310 and the limiting protrusion 200 can also be 6mm or 7mm, etc., where a shock-absorbing pad, such as foam or rubber, can be provided in the gap.

[0056] In one embodiment, please refer to Figures 7 to 9 The electrical control box 300 includes a box body 320 with an open side. The fireproof plate 310 includes a fireproof cover 312. The edge of the fireproof cover 312 is provided with a limiting flange 313. The fireproof cover 312 is provided corresponding to the open side of the box body 320 and abuts against the side of the box body 320 through the limiting flange 313. The distance between the edge of the limiting flange 313 and the open side of the box body 320 is greater than the distance between the limiting protrusion 200 and the fireproof cover 312. It can be understood that the limiting flange 313 bends from the edge of the fireproof cover 312 and abuts against the peripheral wall of the open side of the box body 320. The limiting flange 313 can abut against the outer side of the peripheral wall of the box body 320, or the inner side of the peripheral wall of the box body 320 can abut against the outer side of the limiting flange 313. The distance between the edge of the limiting flange 313 and the opening side of the box body 320 is greater than the distance between the limiting protrusion 200 and the fireproof cover 312, such as Figure 8As shown, this can be understood as follows: when the fireproof cover 312 is normally closed on the box 320, in the direction of the impact of the fireproof cover 312 on the limiting protrusion 200, the distance L1 from the free edge of the limiting flange 313 to the periphery of the opening of the box 320 is greater than the distance L2 from the fireproof cover 312 to the limiting protrusion 200. Thus, when the fireproof plate 310 is subjected to pressure and is restrained by the limiting protrusion 200, the edge of the limiting flange 313 can still abut against the side of the box 320, thereby restricting the flames inside the electrical control box 300 from escaping through the gap between the fireproof cover 312 and the box 320. At the same time, it also ensures the direction of movement of the fireproof cover 312 and prevents the fireproof cover 312 or the fireproof plate 310 from shifting. Therefore, under the restraining action of the limiting protrusion 200, the flames inside the electrical control box 300 can be effectively suppressed from passing through the electrical control box 300 or even the air conditioner, thereby improving the effectiveness and stability of the limiting protrusion 200 in reducing the leakage of flames inside the electrical control box 300.

[0057] Regarding the structural form of the electrical control box 300, in one embodiment, please refer to... Figures 7 to 9 The box body 320 includes an inner box portion 321 and an outer box portion 322. The fireproof plate 310 also includes a protective inner plate 311. The openings of the inner box portion 321 and the outer box portion 322 are located on the same side. The protective inner plate 311 is fastened to the opening side of the inner box portion 321. The outer box portion 322 covers the outer side of the inner box portion 321. The fireproof cover plate 312 is located on the side of the protective inner plate 311 away from the inner box portion 321 and covers the opening side of the outer box portion 322. The limiting flange 313 abuts against the outer side wall of the outer box portion 322. It can be understood that the protective inner plate 311 and the inner box portion 321 are fastened together, which can prevent flames from shooting out in the early stage of a short circuit in the components inside the electrical control box 300. The outer shell and the fireproof cover plate 312 form a second fireproof mechanism, which can effectively delay the tendency of flames to spread even if the inner box portion 321 and the fireproof inner plate are damaged. Without loss of generality, the inner box 321 and the protective interior are made of plastic, while the outer box 322 and the fireproof cover 312 are formed by sheet metal stamping. This not only enhances the fire resistance of the electrical control box 300 but also isolates it from external electromagnetic interference. Furthermore, it strengthens the structural integrity of the electrical control box 300, making it less prone to breakage under internal pressure and improving its resistance to external impacts (such as drops during handling and installation). Both the inner box 321 and the outer box 322 are formed by splicing two half-shells. For the inner box 321, the two half-shells are connected by snap-fitting. For the outer box 322, the two half-shells are formed by overlapping or welding. Of course, in other embodiments, the box body 320 can also be integrally molded from sheet metal using injection molding. Correspondingly, the fireproof cover 310 can be configured similarly to the box body 320.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
