Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to an outdoor unit for an air conditioner. Background Technology

[0002] An air conditioner outdoor unit typically includes core components such as a casing, outdoor fan, compressor, and electrical control box. The internal space of the casing is divided into a compressor chamber and a fan chamber. The outdoor fan is located in the fan chamber and is responsible for driving airflow to enhance heat exchange. The compressor and electrical control box are located in the compressor chamber and are used to compress the refrigerant and control the operation of the entire unit, respectively.

[0003] As a crucial component of the outdoor unit of an air conditioner, the electrical control box is primarily used to integrate and install various control electrical components required for the operation of the air conditioner. The electrical control box typically consists of two parts: the electrical control assembly and the mounting structure. The electrical control assembly houses the various electrical components, enabling the system's electrical control functions; the mounting structure secures the electrical control assembly within the compressor chamber, ensuring its stability and safety during operation.

[0004] To improve heat exchange efficiency and meet higher airflow requirements, some single-fan air conditioner outdoor units employ large-size outdoor fans, resulting in an increased fan cavity volume while the compressor cavity volume is simultaneously compressed. To adapt to installation environments with limited compressor cavity height, related technologies have proposed a technical solution using a foldable installation structure for the electrical control box. However, existing foldable installation structures have significant drawbacks: firstly, the sharp points of screws and other fasteners are easily exposed during folding, posing a risk of puncturing folded electrical components or wiring harnesses, potentially causing short circuits, insulation failures, and other safety hazards; secondly, the foldable structure increases the use of fasteners, hindering production efficiency.

[0032] The outdoor unit 100 of the air conditioner provided in this utility model can have various implementation forms, as detailed below. Figures 1-16 Describe the outdoor unit 100 of the air conditioner.

[0033] It should be noted that the outdoor unit 100, as the outdoor unit of the air conditioner, is usually located outdoors and exchanges heat with the outdoor environment to carry indoor heat to the outside. The air conditioner also includes an indoor unit, which is located indoors and exchanges heat with the indoor environment.

[0034] refer to Figure 1 In one illustrative embodiment of the air conditioner outdoor unit 100 provided by this utility model, the air conditioner outdoor unit 100 includes a housing 1, which is installed outdoors and forms the overall appearance of the air conditioner outdoor unit 100.

[0035] The housing 1 defines an internal space for installing and securing the various components of the outdoor unit 100 of the air conditioner. The housing 1 has a top end and a bottom end, which are the two ends of the housing 1 that are positioned opposite each other in the height direction.

[0036] Continue to refer to Figure 1 , Figure 3The housing 1 may include an air inlet 11. The air inlet 11 is connected to the receiving space and serves as the inlet for external air to flow into the housing 1.

[0037] The housing 1 may include an air outlet 12. The air outlet 12 is connected to the receiving space and serves as the outlet for the heat-exchanged air to flow out of the housing 1.

[0038] Outdoor air from outside the casing 1 enters the casing 1 through the air inlet 11 and is finally exhausted to the outside through the air outlet 12.

[0039] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an air outlet grille connected to the housing 1. The air outlet grille is located at the air outlet 12 to serve both air rectification and safety protection purposes.

[0040] It should be noted that the directions described in the text are based on the direction in which the user faces the outdoor unit 100 of the air conditioner. Specifically, the side of the outdoor unit 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction in which the user faces the outdoor unit 100 of the air conditioner.

[0041] refer to Figure 3 The outdoor unit 100 of the air conditioner may include a partition 2. The partition 2 is disposed in the housing 1 and is used to divide the housing 1 into a fan chamber 14 and a compressor chamber 15.

[0042] The partition 2 is disposed inside the housing 1 along the height direction of the housing. In this embodiment, the fan chamber 14 and the compressor chamber 15 are located on the left and right sides of the housing 1, respectively.

[0043] In some embodiments of this application, the air inlet 11 may be located on the rear side of the housing 1, and the air outlet 12 may be located on the front side of the housing 1.

[0044] Continue to refer to Figure 3 The housing 1 may include a front panel 18, which forms the front end of the housing 1. The air outlet 12 is provided on the front panel 18 of the housing 1.

[0045] Of course, in some other embodiments, the air inlet 11 may also be located on the side of the housing 1, that is, the air inlet 11 may be located on the rear side and / or the side of the housing 1. The air inlet 11 is connected to the fan cavity 14.

[0046] refer to Figure 2 , Figure 3 The housing 1 may include a first side plate 13, which is used to form a press cavity 15. The first side plate 13 forms one end of the housing 1 in the length direction.

[0047] The housing 1 may include a second side plate 17, which forms the other end of the housing 1 in the length direction. The air inlet 11 on the side is formed on the second side plate 17, which is used to form a fan cavity 14.

[0048] In some embodiments of this application, reference continues to be made to Figure 3 The outdoor unit 100 of the air conditioner may include an outdoor heat exchanger 4, which is disposed in the casing 1 and is used to exchange heat with the air entering the casing 1 through the air inlet 11. The outdoor heat exchanger 4 is located inside the air inlet 11.

[0049] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an outdoor fan 3, which is disposed within the fan cavity 14. The outdoor fan 3 may be an axial flow fan.

[0050] refer to Figure 3 The outdoor fan 3 is positioned relative to the outdoor heat exchanger 4 near the air outlet 12. In other words, the outdoor fan 3 is located on the side of the outdoor heat exchanger 4 away from the air inlet 11.

[0051] In this embodiment, the outdoor fan 3 is installed between the outdoor heat exchanger 4 and the air outlet 12. Under the action of the outdoor fan 3, outdoor air enters the casing 1 through the air inlet 11. The outdoor air exchanges heat with the outdoor heat exchanger 4 inside the casing. The outdoor air after heat exchange is discharged from the casing 1 through the air outlet 12 under the drive of the outdoor fan 3.

[0052] The outdoor unit 100 of the air conditioner may include a compressor, which is located in the compressor chamber 15.

[0053] The air conditioner may include a throttling device for limiting airflow. The throttling device may be located in the outdoor unit 100 or the indoor unit of the air conditioner.

[0054] An air conditioner may include a refrigerant circuit. A refrigerant circuit is formed by connecting pipes between the indoor unit and the outdoor unit 100 of the air conditioner. Through this refrigerant circuit, the air conditioner allows the refrigerant to circulate sequentially through the compressor, condenser, throttling device, and evaporator, enabling it to perform indoor cooling or heating.

[0055] An air conditioner may include an indoor unit, which includes an indoor heat exchanger.

[0056] The indoor heat exchanger and outdoor heat exchanger 4 are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0057] Refrigeration and heating cycles include compression, condensation, expansion, and evaporation processes. They provide cooling or heating to the indoor space through the heat absorption and release processes of the refrigerant, thereby regulating the temperature of the indoor space.

[0058] The compressor compresses the refrigerant gas into a high-temperature, high-pressure state and discharges the compressed refrigerant gas, which then flows into the condenser.

[0059] The condenser condenses the compressed, high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.

[0060] The liquid refrigerant flowing out of the condenser enters the throttling device, which expands the high-temperature, high-pressure liquid refrigerant after condensation in the condenser into a low-pressure liquid refrigerant.

[0061] The low-pressure liquid refrigerant flowing out of the throttling device enters the evaporator. As the liquid refrigerant flows through the evaporator, it absorbs heat and evaporates into a low-temperature, low-pressure refrigerant gas. The low-temperature, low-pressure refrigerant gas returns to the compressor.

[0062] The evaporator achieves its cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout this entire cycle, the air conditioner regulates the temperature of the indoor space.

[0063] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an electrical control box, which is vertically arranged in the compressor chamber 15. This not only reduces dust accumulation in the electrical control box, but also, in the event of a fire in the electrical control box, the compressor chamber 15 is a sealed metal chamber that can effectively prevent the spread of flames, improve the fire resistance rating, and effectively ensure dustproof and fireproof performance.

[0064] In some embodiments of this application, the electrical control box may include an electrical control component, which is located above the compressor and is used to control the operating status of multiple components in the outdoor unit 100 of the air conditioner.

[0065] The electrical control box may include a mounting structure 7 for mounting electrical control components to ensure that the electrical control box is vertically mounted on the top of the press chamber 15.

[0066] Driven by multiple factors such as rising energy efficiency standards, cost control, and installation space constraints, single-fan, small-casing models with high energy efficiency (36 kW·h) to low energy efficiency (48 kW·h) capacity have become the mainstream specifications for export to the Middle East, Africa, ASEAN, and Eastern Europe in recent years. To achieve higher air volume limits, outdoor units 100 in this capacity range generally use large-sized outdoor fans 3, resulting in an increase in the volume of the fan cavity 14, while the volume of the compressor cavity 15 is simultaneously compressed, posing unprecedented space challenges to the layout of the compressor and its associated electronic control system.

[0067] To address the aforementioned technical issues, in some embodiments of this application, a foldable mounting structure 7 is used to install the electronic control components, simultaneously satisfying dustproof, fireproof, high component density, and ease of production within a height-constrained housing 1.

[0068] Specifically, reference Figure 4 The mounting structure 7 may include a first mounting plate 71, which extends along the height direction of the housing 1 and is connected between the partition 2 and the first side plate 13.

[0069] In this embodiment, the existing partition 2 and the first side plate 13 are used as fulcrums to install the electrical control box, eliminating the need for additional brackets and reducing the number of parts. Furthermore, the two ends of the first mounting plate 71 are fixed to form a "bridge" structure, which has higher vibration resistance than a single-end cantilever structure.

[0070] The electronic control assembly may include a first electronic control assembly 5, which is mounted on a first mounting plate 71. The first mounting plate 71 has a first mounting surface 714, which provides a mounting position for the first electronic control assembly 5. (See reference) Figure 5 The first electrical control component 5 is installed on the first mounting surface 714.

[0071] refer to Figure 4 The mounting structure 7 may include a second mounting plate 72, which is foldably connected to the first mounting plate 71. The second mounting plate 72 can provide mounting positions for electronic control components.

[0072] Specifically, reference Figures 6-9 One end of the second mounting plate 72 is rotatably connected to the first mounting plate 71, and the other end of the second mounting plate 72 is detachably connected to the first mounting plate 71, so that the second mounting plate 72 can switch between an unfolded position and a folded position relative to the first mounting plate 71.

[0073] refer to Figure 7 When folded, the orthographic projection of the second mounting plate 72 along the width direction of the housing 1 at least partially falls into the first mounting surface 714. The second mounting plate 72 has a second mounting surface 725.

[0074] The electronic control assembly may include a second electronic control assembly 6, which is mounted on the second mounting surface 725. (Continue to refer to...) Figure 7 When the second mounting plate 72 is in the folded position, the second mounting surface 725 is the side of the second mounting plate 72 that is away from the first mounting surface 714.

[0075] In this embodiment, by distributing the electrical control components on the foldable first mounting plate 71 and the second mounting plate 72, a three-dimensional and foldable layout of the electrical control box can be achieved in the height direction of the housing 1. This allows for the arrangement of more electrical components within the limited height space of the press cavity 15 without increasing the overall height of the housing 1, and simultaneously meets the requirements of dustproof, fireproof and convenient production and installation.

[0076] In some embodiments of this application, the mounting structure 7 may include a plurality of first fasteners 91 for fixing the second electronic control component 6 to the second mounting surface 725. The first fasteners 91 pass through the second mounting plate 72.

[0077] For example, the first fastener 91 can be a screw, and the second mounting plate 72 is provided with a first mounting hole 74 for the first fastener 91 to pass through and connect.

[0078] When the first fastener 91 secures the second electronic control component 6, its pointed tip will protrude from the back of the second mounting plate 72, which can easily puncture the corresponding first electronic control component 5 during installation, transportation or vibration.

[0079] To address the aforementioned technical solutions, in some embodiments of this application, reference is made to... Figure 9 , Figure 10 The outdoor unit 100 of the air conditioner may include a protective plate 8, which is disposed on the side of the second mounting plate 72 opposite to the second electronic control component 6, and is used to cover the first fastener 91.

[0080] The protective plate 8 and the second electronic control assembly 6 are respectively disposed on opposite sides of the second mounting plate 72. When the second mounting plate 72 is in the folded position, the protective plate 8 is located on the side of the second mounting plate 72 facing the first mounting surface 714 to protect the tip of the first fastener 91 from piercing the electrical components in the first electronic control assembly 5.

[0081] In this embodiment, by setting a protective plate 8 to cover the tip of the first fastener 91, a physical barrier is formed between the first fastener 91 and its corresponding first electronic control component 5, completely eliminating the risk of the first fastener 91 on the second mounting plate 72 puncturing the first electronic control component 5, and significantly improving the long-term reliability and safety of the product.

[0082] For example, the protective plate 8 can selectively cover the portion of the first fastener 91 corresponding to the first electronic control component 5 to eliminate the harmful effect of the tip of the first fastener 91 on the first electronic control component 5, while the remaining first fasteners 91 located in the harmless area can be left uncovered by the protective plate 8, which can save material costs to a certain extent.

[0083] In some other embodiments, the second mounting plate 72 can be rotated and unfolded or folded relative to the first mounting plate 71, and the orthographic projection of the folded second mounting plate 72 along the width direction of the housing 1 at least partially falls onto the first mounting plate 71. The first electronic control component 5 is arranged on the first mounting plate 71, and the second electronic control component 6 and the protective plate 8 are respectively arranged on the two sides of the second mounting plate 72. When the second mounting plate 72 is folded, the first electronic control component 5 and the protective plate 8 are respectively arranged on the mutually facing sides of the first mounting plate 71 and the second mounting plate 72.

[0084] In this embodiment, the first electronic control component 5 and the protective plate 8 are respectively disposed on the mutually facing sides of the first mounting plate 71 and the second mounting plate 72, which completely eliminates the risk of the tip of the first fastener 91 piercing the first electronic control component 5 and significantly improves the overall operational reliability.

[0085] In some embodiments of this application, the second mounting plate 72 is disposed at the bottom of the first mounting plate 71. When installing the first electronic control component 5, the second mounting plate 72 can be directly fixed by simply rotating it open, and then rotated back after fixing. This ensures that the installation of electronic control components with different folding directions does not affect each other, and also ensures that the second mounting plate 72 is fixed in the optimal way after the first electronic control component 5 is fixed, thus ensuring production efficiency.

[0086] In the event of a refrigerant leak, a flammable mixture may form within the compressor chamber 15. Simultaneously, relays, fuses, or circuit boards in the electrical control components may generate electrical sparks sufficient to ignite the flammable gas during normal switching operations, posing an explosion risk. Therefore, in some embodiments of this application, an explosion-proof box 52 is provided within the compressor chamber 15.

[0087] In this embodiment, electrical components in the electronic control assembly that may generate sparks are placed inside the explosion-proof box 52 to reduce the possibility of electrical sparks coming into contact with refrigerant and improve the safety of the air conditioner.

[0088] Reference image Figure 9 , Figure 11 The first electronic control component 5 may include an explosion-proof box 52. The first mounting surface 714 is recessed in a direction away from the second mounting plate 72 to form a receiving portion 717, which is located above the second mounting plate 72, and the explosion-proof box 52 is housed in the receiving portion 717.

[0089] In this embodiment, by providing a receiving portion 717, the first mounting plate 71 protrudes partially, and the explosion-proof box 52 is embedded in the receiving portion 717. This not only effectively avoids the increased cost caused by the first mounting plate 71 being deepened as a whole, but also avoids the problem of interference between the first mounting plate 71 and the four-way valve on its rear side.

[0090] In some embodiments of this application, reference is made to Figure 12The first electronic control component 5 may include a capacitor 51, which is located at the bottom of the first mounting surface 714.

[0091] The second electrical control component 6 may include a terminal block 61, and the capacitor 51 and the terminal block 61 are folded together in the height direction of the housing 1.

[0092] refer to Figure 12 , Figure 13 Terminal block 61 is mounted on the second mounting plate 72. Terminal block 61 is positioned close to the outside of capacitor 51 to facilitate wiring operations. The wire harness of terminal block 61 on the front side of capacitor 51 can be connected to capacitor 51 with the shortest and most direct path, simplifying the wire harness layout and improving production convenience.

[0093] Furthermore, the capacitor 51 is located below the explosion-proof box 52. In the width direction of the housing 1, the capacitor 51 is closer to the explosion-proof box 52 than the terminal block 61, which facilitates the electrical connection between the capacitor 51 and the electrical components inside the explosion-proof box 52 and improves production convenience.

[0094] In some embodiments of this application, reference is made to Figure 14 The height of the terminals of capacitor 51 is higher than the height of the second mounting plate 72 to avoid the second mounting plate 72 obstructing the view and to facilitate wiring.

[0095] In some embodiments of this application, reference is made to Figure 16 The first mounting plate 71 may include a second plate body 712, and a first mounting surface 714 is formed on the second plate body 712.

[0096] The first mounting plate 71 may include a first plate body 711, which is connected to one end of the second plate body 712. (Continue to the previous section) Figure 16 The first plate 711 is connected to the second plate 712 to form an "L" shaped flange, and the first plate 711 is connected and fixed to the partition 2.

[0097] The first mounting plate 71 may include a third plate body 713, which is connected to the other end of the second plate body 712. The third plate body 713 is connected to the first side plate 13.

[0098] Continue to refer to Figure 16 The first mounting plate 711, the second mounting plate 712, and the third mounting plate 713 are connected sequentially. By segmenting the first mounting plate 71, its functions can be divided. This allows each of the first mounting plate 711, the second mounting plate 712, and the third mounting plate 713 to perform the functions of connecting, installing, and connecting electrical control components. This not only solves the problem of installation interference between the connection and fixing structure of the first mounting plate 71 and the partition 2 and the first side plate 13 and the electrical control components, but also ensures the installation area and assembly convenience of the electrical control components.

[0099] In some embodiments of this application, reference is made to Figure 16 One end of the second mounting plate 72 is hinged to the first mounting plate 71 via a hinge 73. The axis of rotation of the second mounting plate 72 extends along the height direction of the housing 1.

[0100] The hinge 73 allows the second mounting plate 72 to rotate and unfold in the horizontal plane, providing operators with a fully unfolded, unobstructed, and easy-to-operate optimal working position when installing electrical components at the bottom of the first mounting plate 71, thus improving the maintainability of the product.

[0101] In this embodiment, when the second mounting plate 72 is rotated to the unfolded position, the entire first electronic control component 5 can be exposed. After unfolding, the explosion-proof box 52, capacitor 51, circuit board, power module, etc. are all visible, and maintenance can be completed in one go, improving maintenance efficiency.

[0102] In some embodiments of this application, a first through hole 724 is provided at the end of the second mounting plate 72 away from the rotating end. The first through hole 724 is used for the second fastener 92 to pass through.

[0103] In this embodiment, the first through hole 724 provides a single-point locking position at the folded position to prevent the second mounting plate 72 from shaking during operation and transportation.

[0104] refer to Figure 12 , Figure 16 The third plate 713 is provided with a second through hole 715, and the second fastener 92 passes through the first through hole 724 and the second through hole 715 in sequence and is connected to the first side plate 13.

[0105] In this embodiment, only one second fastener 92 is used to pass through the second mounting plate 72 and the first mounting plate 71 and lock it to the first side plate 13, realizing "one piece with three fasteners", which significantly saves the number of second fasteners 92 and their corresponding assembly time, and improves production efficiency.

[0106] It is understood that a second mounting hole is provided on the first side plate 13, and the second fastener 92 is installed in the second mounting hole to fix the second mounting plate 72 and the first mounting plate 71 together on the first side plate 13.

[0107] In some embodiments of this application, the second mounting plate 72 may include a fourth plate body 721, which is used to mount the second electronic control component 6 and the protective plate 8.

[0108] The second mounting plate 72 may include a fifth plate body 722, which is connected to one end of the fourth plate body 721. The fifth plate body 722 is connected to the first mounting plate 71 via a hinge 73.

[0109] By setting the fifth plate 722 to provide an independent and dedicated mounting position for the hinge 73, it avoids drilling holes in the component area (fourth plate 721), ensuring that the fourth plate 721 is intact and flat, and avoiding interference with the installation of the second electronic control component 6.

[0110] The second mounting plate 72 may include a sixth plate 723, which is connected to the other end of the fourth plate 721. The fifth plate 722 is detachably connected to the first mounting plate 71 and the first side plate 13 via a second fastener 92.

[0111] refer to Figure 16 The fifth body, the fourth plate 721 and the sixth plate 723 are integrally formed to form a concave structure, which not only improves the overall rigidity, but also effectively avoids the capacitor 51 at the bottom.

[0112] In some embodiments of this application, at least one positioning part 22 is provided on the partition 2. (See reference...) Figure 15 The positioning part 22 can be a socket structure.

[0113] The first plate 711 is provided with a hook 716, which is adapted to be connected to the positioning part 22 to position the first mounting plate 71 on the partition 2.

[0114] In this embodiment, the first mounting plate 71 is pre-fixed and precisely positioned by the hook 716 engaging with the positioning part 22, which simplifies the installation difficulty of the first mounting plate 71, facilitates subsequent fixing operations, and further improves the assembly speed of the production line.

[0115] Two positioning parts 22 and two hooks 716 are provided respectively. For example, see reference... Figure 16 The first plate 711 has a cutting groove, and two hooks 716 are formed by folding the first plate 711 through the two cutting grooves respectively.

[0116] In this embodiment, by directly folding the hook 716 from the first plate 711, not only is production efficiency improved and structural stability enhanced, but additional material and process requirements are also reduced, production costs are lowered, and design flexibility and appearance quality are improved.

[0117] In some embodiments of this application, reference is made to Figure 15 The partition plate 2 has a mounting part 21 protruding on the side facing the press chamber 15. The third fastener 93 passes through the first plate 711 and is fixed on the mounting part 21 so that the first plate 711 is fixedly connected to the partition plate 2.

[0118] Specifically, a third mounting hole 23 is provided through the mounting part 21, and a connecting part adapted to the mounting part 21 is formed on the second plate 712. A third through hole 718 is provided on the connecting part, and a third fastener 93 passes through the third through hole 718 and is connected to the third mounting hole 23 so that the first mounting plate 71 is fixedly connected to the partition plate 2.

[0119] For example, the mounting part 21 is a pressed structure on the partition 2, that is, the mounting part 21 is integrally formed by the pressing process of the partition 2.

[0120] The mounting part 21 of the pressed structure has high strength. The mounting part 21 of the pressed structure forms a local reinforcement structure on the partition 2, which provides a more solid support point for fixing the first mounting plate 71, ensuring that the fixed connection between the partition 2 and the first plate 711 has sufficient support capacity and structural strength, improving the connection firmness between the first mounting plate 71 and the partition 2, and ensuring the stability of the entire electrical control system of the air conditioner outdoor unit 100.

[0121] In some embodiments of this application, the first electronic control component 5 may include a circuit board. (See reference...) Figure 13 The circuit board is mounted on the first mounting surface 714 via the housing 53, and the circuit board is located above the explosion-proof box 52.

[0122] In some embodiments of this application, a maintenance port 16 is provided on the housing 1, the maintenance port 16 is covered by a maintenance plate 19, and the first mounting surface 714 is the side of the first mounting plate 71 facing the maintenance port 16. For example, see reference... Figure 5 The maintenance port 16 is located on the front side of the housing 1.

[0123] In this embodiment, by setting a maintenance port 16 facing the electronic control component, after the worker removes the maintenance plate 19, removes the second fastener 92 and rotates and unfolds the second mounting plate 72 on site, all electrical components of the first electronic control component 5 can be directly accessed, realizing "front-facing maintenance" without disassembling the entire machine casing 1, thus improving maintenance convenience.
