Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, specifically to an air conditioner control box assembly and an air conditioner outdoor unit. Background Technology

[0002] As the "control center" of the outdoor unit, the electrical control box assembly integrates key electrical components such as the compressor controller, fan controller, relays, and capacitors, and is one of the core components that ensure the normal operation of the air conditioner. The electrical control box assembly of the outdoor unit of the existing air conditioner is usually installed on the windproof panel. The windproof panel divides the interior of the outdoor unit into the compressor chamber (which houses the compressor, refrigerant pipes, etc.) and the fan chamber (which houses the fan, heat exchanger, etc.). The electrical control box assembly must be kept in close contact with and parallel to the windproof panel to ensure the heat dissipation effect of the electrical components and the coordination with other components.

[0003] However, the relevant technology has at least one of the following problems: In order to adapt to the limited installation space inside the outdoor unit, the existing protective plates are generally designed as thin flat structures, with a thickness of only 2-3mm, and no special gripping structure is provided; when maintenance personnel remove the protective plates, they need to use tools such as flathead screwdrivers, fingernails, or body parts to pry the edges of the protective plates, which is not only cumbersome and time-consuming (an average of 3-5 minutes for a single removal and placement operation), but also very likely to cause cracks on the edges of the protective plates, peeling off the surface coating, or even deformation of the protective plates, affecting the protective performance of the electrical control box (such as dustproof and waterproof); when installing the protective plates, due to the lack of gripping points, it is difficult to accurately align with the installation opening of the base, which easily leads to installation misalignment, further prolonging maintenance time. Utility Model Content

[0004] This invention solves the technical problem that, during the disassembly and installation of protective plates, the lack of gripping points can easily lead to misalignment and deformation of the protective plates.

[0005] To address the aforementioned problems, this utility model provides an electrical control box assembly for an air conditioner, applied to an outdoor unit. The outdoor unit includes: a windproof panel that divides the internal cavity of the outdoor unit into a compressor cavity and a fan cavity. The electrical control box assembly includes: a base with an opening on one side; a protective plate that is detachably mounted on the base via the opening, and a clamping space for clamping the upper section of a refrigerant pipe is formed between the protective plate and the base; and a handle structure located on the side of the protective plate away from the base, specifically at the top of the protective plate.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: The base is the core component connecting the electrical control box assembly and the windproof upright plate, and it also provides an installation foundation for the protective plate, electrical components, and refrigerant pipes. The handle structure is located on the top of the protective plate on the side (back) away from the base, and it protrudes outward relative to the back of the protective plate, providing users with a clear gripping point. No tools are needed for removal and placement; only manual gripping is required, solving the problem of difficult removal and placement of the protective plate, while also preventing damage such as cracking and deformation of the protective plate edges. Users can accurately align the handle structure with the base opening, significantly reducing the installation misalignment rate. At the same time, it retains clamping space for the upper section of the refrigerant pipe, ensuring that the refrigerant pipe does not shift under vibration, thus meeting the dual requirements of "easy disassembly and assembly" and "pipeline fixation."

[0007] In one embodiment of this utility model, the handle structure includes a wiring channel, which is formed in the top area of ​​the handle structure and the opening of the wiring channel faces upward, for storing the relevant wiring of the electrical control box assembly.

[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: The wiring trough is located at the handle structure with an upward opening, used to store the relevant wiring of the electrical control box components, solving the problem of messy wiring. The wiring is stably limited within the wiring trough, avoiding noise caused by vibration and friction between the wiring and other components during air conditioner operation. The wiring trough also plays a role in centralized storage and limiting of the wiring, preventing the wiring from being scattered between the protective plate and the base or resting on the refrigerant pipes. At the same time, the upward opening design of the wiring trough makes it easy for maintenance personnel to check the status of the wiring at any time and troubleshoot wiring faults.

[0009] In one embodiment of this utility model, the handle structure further includes a stop portion, which is located in the area of ​​the handle structure where the wiring groove is provided, and is located in the top area of ​​the handle structure.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: during the operation of the air conditioner, the stop part can prevent the wires from coming off or moving due to vibration, ensuring stable wire connection and improving the stability of wire storage.

[0011] In one embodiment of this utility model, the electrical control box assembly further includes a reinforcing part, which is located in the bottom area of ​​the handle structure and connects the handle structure and the guard plate.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the reinforcement can distribute the stress of the handle structure to the entire guard plate, improve the connection strength, enhance the fracture resistance of the handle structure, and extend the service life.

[0013] In one embodiment of this utility model, the electrical control box assembly further includes: a folded edge structure, which is disposed in the bottom area of ​​the protective plate, and the folded edge structure includes: a first flange, which is disposed on the side of the protective plate away from the base and extends along the side away from the base; and a second flange, which is connected to the first flange and extends along the direction away from the handle structure.

[0014] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Since the bottom of the thin protective plate is prone to sagging due to gravity or vibration, the folded edge structure is set up to enhance the rigidity of the bottom of the protective plate through the "L-shaped" folded edge design, preventing the protective plate from sagging and deforming; at the same time, the second folded edge can serve as a "positioning reference" when installing the protective plate, making it easier to align with the bottom installation structure of the base, and further improving the installation accuracy.

[0015] In one embodiment of this utility model, the base is fitted to the windproof upright.

[0016] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: increasing the contact area between the base and the windproof upright, improving the installation stability of the base, preventing the base from shaking during vibration, and improving the overall structural stability.

[0017] In one embodiment of this utility model, the base includes: a mounting plate; a support portion, the support portion connecting the mounting plate and the windproof upright plate; wherein, a through hole is provided on the windproof upright plate, and the support portion passes through the through hole and is secured to the lower edge of the through hole.

[0018] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the support part is a bottom locking structure located at the bottom of the mounting plate, and its extension direction is away from the handle structure; a locking hole is provided through the lower position of the windproof upright plate, and the support part is inserted and matched with the windproof upright plate. The support part passes through the locking hole and holds the lower edge of the locking hole. The windproof upright plate provides upward support for the base of the electrical control box assembly at the locking hole. The locking structure between the support part and the locking hole realizes "one-click positioning" of the base.

[0019] In one embodiment of this utility model, the electrical control box assembly further includes a buffer pad, which is fitted onto the side of the protective plate near the base, and the shape of the buffer pad is adapted to the shape of the clamping space.

[0020] Compared with existing technologies, the technical effects achieved by this solution are as follows: setting up buffer pads can prevent the refrigerant pipe from directly contacting the protective plate, prevent the edge of the protective plate from scratching the galvanized layer on the surface of the refrigerant pipe, and reduce the risk of refrigerant leakage; it can also absorb a large amount of refrigerant pipe vibration energy and block the transmission of refrigerant pipe vibration to the base, thereby reducing operating noise and meeting indoor environmental noise standards.

[0021] In one embodiment of this utility model, a gap is left between the two ends of the handle structure and the side of the guard plate to prevent the handle structure from interfering with the outdoor unit of the air conditioner.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the gap design is designed to accommodate two fingers for a comfortable grip; at the same time, it ensures that the handle structure does not collide with components such as the outdoor unit side panel and fan bracket.

[0023] On the other hand, this utility model also provides an outdoor unit for an air conditioner, including: an electrical control box assembly of the air conditioner as described in Embodiment 1 above; a housing assembly, the housing assembly having a receiving cavity, and the housing assembly including a chassis and a right side plate; a windproof upright plate, the windproof upright plate being installed on the chassis, the windproof upright plate dividing the receiving cavity into a first cavity and a second cavity, and the first cavity having a compressor and a base, the compressor being located on the lower side of the base, and the second cavity having a fan and a protective plate.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the windproof upright plate divides the housing cavity into a first cavity and a second cavity, making the layout of the outdoor unit of the air conditioner neater.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) The handle structure is located on the top of the side of the guard plate away from the base (back side) and is convex relative to the back of the guard plate, providing a clear gripping point for the user. No tools are needed when taking it out or putting it in, only manual gripping is required, which solves the problem of difficult removal and placement of the guard plate, and avoids damage such as cracking or deformation of the guard plate edges. (2) The wiring trough is located at the handle structure with the opening facing upward. It is used to store the relevant wiring of the electrical control box assembly, solving the problem of messy wiring. The wiring is stably limited in the wiring trough, avoiding the noise generated by the wiring due to vibration and friction with other components during the operation of the air conditioner. (3) The stop part can prevent the line from coming off or moving due to vibration, ensuring the line connection is stable and improving the stability of line storage. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1 See Figure 1 This utility model provides an electrical control box assembly for an air conditioner, applied to an outdoor unit 1. The outdoor unit 1 includes a windbreak panel 20, which divides the internal cavity of the outdoor unit 1 into a compressor cavity and a fan cavity. Figures 2-3 The electrical control box assembly includes: a base 210, a protective plate 220, and a handle structure 230. The base 210 has an opening structure on one side. The protective plate 220 is detachably installed on the base 210 through the opening structure, and a clamping space for clamping the upper section 30 of the refrigerant pipe is formed between the protective plate 220 and the base 210. The handle structure 230 is located on the side of the protective plate 220 away from the base 210, and the handle structure 230 is located in the top area of ​​the protective plate 220.

[0030] In one specific embodiment, the electrical control box assembly specifically includes: a base 210 with an opening structure on one side, a protective plate 220 that is detachably installed on the base 210 through the opening structure and forms a clamping space for the upper section 30 of the refrigerant pipe with the base 210, and a handle structure 230 located on the side of the protective plate 220 away from the base 210 and in the top region of the protective plate 220. The base 210 is the core component connecting the electrical control box assembly and the windproof upright plate 20, and also provides an installation base for the protective plate 220, electrical components, and refrigerant pipes. The protective plate 220 can be detachably installed through the opening structure of the base 210 (such as snap-fit ​​or slot fit). The protective plate 220 and the base 210 form a closed space to protect the internal electrical components, and at the same time form a "clamping space"—this space is used to clamp the upper section of the refrigerant pipe (the section of the refrigerant pipe near the windproof upright plate 20). The clamping force of the protective plate 220 and the base 210 is used to fix the refrigerant pipe and prevent the refrigerant pipe from vibrating and shifting. The handle structure 230 is located on the top of the side (back) of the protective plate 220 away from the base 210, and is convex relative to the back of the protective plate 220, providing the user with a clear grip point. No tools are needed when picking up and putting down the protective plate 220; only manual gripping is required. This solves the problem of difficult picking up and putting down the protective plate 220, and also prevents damage such as cracking or deformation of the protective plate 220 edges. Users can accurately align the handle structure 230 with the opening of the base 210 by holding it, which significantly reduces the installation misalignment rate; at the same time, the upper section 30 of the refrigerant pipe is reserved to ensure that the refrigerant pipe does not shift under vibration, thus meeting the dual requirements of "easy disassembly and assembly" and "pipe fixation".

[0031] Further, see Figure 3 The handle structure 230 includes a wiring channel 231, which is located in the top area of ​​the handle structure 230 and has an upward opening, for storing the relevant wiring of the electrical control box assembly.

[0032] Specifically, the cable tray 231 is located in the top area of ​​the handle structure 230, specifically at the top of the arc-shaped convex surface of the handle structure 230, and is set along the length of the handle structure 230. The upward-opening cable tray 231 allows for centralized storage of cables, avoiding direct contact between cables and refrigerant pipes (preventing accelerated aging of the insulation layer due to high and low temperatures), and also preventing cables from tangling (reducing friction noise and the risk of breakage). Integrating the cable tray 231 into the handle structure 230 eliminates the need for additional space in the outdoor unit, achieving a combination of "grip function" and "cable storage function". At the same time, the upward-facing opening of the cable tray 231 makes it easy for maintenance personnel to directly place or remove cables from the cable tray 231 during installation or maintenance, making the operation convenient and eliminating the need to disassemble the protective plate 220 or other components.

[0033] Preferably, the side of the protective plate 220 is provided with a wiring channel 221, which is connected to the wiring trough 231. The wiring channel 221 and the wiring trough 231 are connected to improve the wiring storage function.

[0034] Furthermore, the handle structure 230 also includes a stop portion 232, which is located in the area of ​​the handle structure 230 where the cable routing groove 231 is provided, and the stop portion 232 is located in the top area of ​​the handle structure 230.

[0035] Specifically, the stop part 232 is provided in the area where the cable tray 231 is opened in the handle structure 230, and is located in the top area of ​​the handle structure 230 (i.e., the edge of the slot of the cable tray 231). Its function is to prevent the cable from coming out of the slot of the cable tray 231. Especially when the outdoor unit is installed at an angle (such as 30-45° on the roof) or under severe vibration, the stop part 232 can effectively limit the displacement of the cable and ensure that the cable is always within the cable tray 231.

[0036] Preferably, the stop portion 232 is semi-circular or rectangular in shape, with a height of 3-5mm, and is spaced apart along the length of the cable tray 231 (spacing 20-30mm), or is continuously arranged as a "stop edge".

[0037] Furthermore, the electronic control box assembly also includes a reinforcing part 240, which is located in the bottom region of the handle structure 230 and connects the handle structure 230 and the guard plate 220.

[0038] Specifically, because the handle structure 230 is subjected to stress for a long time (such as the pulling force during disassembly and assembly, and the pressure when gripping), it is prone to breakage at the connection with the guard plate 220. The reinforcing part 240 can distribute the stress on the handle structure 230 to the entire guard plate 220, improve the connection strength, increase the fracture resistance of the handle structure 230, and extend its service life.

[0039] Preferably, the reinforcing part 240 is shaped like a triangular rib or a rectangular boss, with a thickness of 4-6 mm and a quantity of 2-3 (evenly distributed along the length of the handle structure 230); the material of the reinforcing part 240 is the same as that of the handle structure 230 and the guard plate 220, and it is integrally injection molded.

[0040] Furthermore, the electrical control box assembly also includes: a folded edge structure 250, which is disposed in the bottom area of ​​the guard plate 220, and the folded edge structure 250 includes: a first flange 251 and a second flange 252. The first flange 251 is disposed on the side of the guard plate 220 away from the base 210 and extends along the side away from the base 210; the second flange 252 is connected to the first flange 251 and extends in the direction away from the handle structure 230.

[0041] Specifically, the first flange 251 is located on the side of the guard plate 220 away from the base 210 and extends in a direction away from the base 210; the second flange 252 is perpendicularly connected to the first flange 251 (with an included angle of 90°) and extends in a direction away from the handle structure 230; since the bottom of the thin guard plate 220 is prone to sagging due to gravity or vibration, the flange structure 250 is set to enhance the rigidity of the bottom of the guard plate 220 through the "L-shaped" flange design to prevent the guard plate 220 from sagging and deforming; at the same time, the second flange 252 can serve as a "positioning reference" when installing the guard plate 220, making it easier to align with the bottom mounting structure of the base 210 and further improving the installation accuracy.

[0042] Furthermore, the base 210 is fitted to the windproof upright plate 20.

[0043] Specifically, the base 210 serves as the fixed foundation for the electrical control box assembly, and is fitted closely to the windproof upright plate 20, providing stable support for the entire assembly. Simultaneously, in conjunction with the refrigerant pipe clamping structure, the electrical control box assembly and the outdoor unit 1 of the air conditioner work in close coordination, increasing the contact area between the base 210 and the windproof upright plate 20, improving the installation stability of the base 210, preventing the base 210 from shaking during vibration, and enhancing the overall structural stability. Fitting the base 210 closely to the windproof upright plate 20 also utilizes the heat dissipation performance of the windproof upright plate 20 to assist in heat dissipation of the internal electrical components of the base 210, extending the component lifespan.

[0044] Furthermore, the base 210 includes: a mounting plate 211 and a support part 212, the support part 212 connecting the mounting plate 211 and the windproof upright plate 20; wherein, a through hole is provided on the windproof upright plate 20, and the support part 212 passes through the through hole and is locked at the lower edge of the through hole.

[0045] Specifically, the support part 212 is a bottom locking structure located at the bottom of the mounting plate 211, and its extension direction is away from the handle structure 230; a through hole is provided at the lower position of the windproof upright plate 20, and the support part 212 is inserted and engaged with the windproof upright plate 20. The support part 212 passes through the through hole and holds the lower edge of the through hole. The windproof upright plate 20 provides upward support for the base 210 of the electrical control box assembly at the through hole. The engagement structure between the support part 212 and the through hole realizes the "one-click positioning" of the base 210.

[0046] Furthermore, the electrical control box assembly also includes a buffer pad 260, which is attached to the side of the protective plate 220 near the base 210, and the shape of the buffer pad 260 is adapted to the clamping space.

[0047] Specifically, the buffer pad 260 can prevent the refrigerant pipe from directly contacting the protective plate 220, prevent the edge of the protective plate 220 from scratching the galvanized layer on the surface of the refrigerant pipe, and reduce the risk of refrigerant leakage; it can also absorb a large amount of refrigerant pipe vibration energy and block the transmission of refrigerant pipe vibration to the base 210, thereby reducing operating noise and meeting indoor environmental noise standards; at the same time, the buffer pad 260 can also fill the gap between the refrigerant pipe and the protective plate 220, and improve clamping stability.

[0048] Furthermore, gaps are left between the two ends of the handle structure 230 and the side of the guard plate 220 to prevent the handle structure 230 from interfering with the outdoor unit 1 of the air conditioner.

[0049] Specifically, the gap design is designed to accommodate two fingers for a comfortable grip; at the same time, it ensures that the handle structure 230 does not collide with components such as the outdoor unit side panel and fan bracket.

[0050]

Example 2

[0051] Specifically, the outer casing assembly includes a right side plate 11, a left side plate 12, a back plate 13, and a chassis 14. The back plate 13 connects the left side plate 12 and the right side plate 11, and the right side plate 11, the back plate 13, the left side plate 12, and the chassis 14 form a receiving cavity. The outer casing assembly is provided with a windproof upright plate 20, which divides the receiving cavity into a first cavity 141 and a second cavity 142. The chassis 14 is inserted into the windproof upright plate 20. The first cavity 141 is provided with a compressor and a base 210, with the compressor located on the lower side of the base 210. The second cavity 142 is provided with a heat exchanger, which is installed on the chassis 14 and adjacent to the windproof upright plate 20. The heat exchanger is provided with a receiving groove, and a fan and a protective plate 220 are provided in the receiving groove.
