[0002] Currently, the outdoor unit of a household air conditioner contains an electrical control box. To ensure the normal operation of the electrical control box, ventilation openings need to be made on the electrical control box to allow for ventilation and heat dissipation.

[0003] In the existing technology, the electrical control box uses a single air inlet and outlet, which has poor waterproof performance. If a waterproof structure is required, it will increase the cost of parts and the assembly process. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide an outdoor unit for an air conditioner. This outdoor unit has a second air inlet on the front cover, which is connected to a third air inlet on the electrical control box. It also has a second air outlet on the front cover, which is connected to a third air outlet on the electrical control box. This dual air inlet and dual air outlet design not only ensures ventilation and heat dissipation for the electrical control box but also improves its waterproofness.

[0005] To achieve the above objectives, an outdoor unit of an air conditioner is provided according to an embodiment of the present invention, comprising: a casing, wherein a first air inlet is provided on the circumferential side wall of the casing and a first air outlet is provided on the top; a compressor, wherein the compressor is disposed within the casing; an outdoor heat exchanger, wherein the outdoor heat exchanger is disposed within the casing and connected to the compressor; an outdoor fan, wherein the outdoor fan is used to introduce airflow from outside the casing into the casing through the first air inlet, and after heat exchange by the outdoor heat exchanger, output it to the outside through the first air outlet; and an electrical control box, wherein the electrical control box is provided with... The device is located within the housing; characterized in that the housing comprises: a main housing, the front side of which is at least partially open; a front cover, which is disposed in the open portion on the front side of the main housing, and the electrical control box is disposed within the front cover; wherein the front cover has a second air inlet and a second air outlet communicating with the interior of the housing, the electrical control box has a third air inlet and a third air outlet, the second air inlet and the third air inlet are both downwardly open and correspondingly connected, and the second air outlet and the third air outlet are both rearwardly open and correspondingly connected.

[0006] The above technical solution has the following advantages or beneficial effects: by setting corresponding air inlets and corresponding air outlets on the front cover and the electrical control box, this dual air inlet and dual air outlet design can effectively prevent water from splashing into the electrical control box, thereby enabling the electrical control box of the outdoor unit of the air conditioner to not only ventilate and dissipate heat, but also improve its waterproofness.

[0007] According to some embodiments of the present invention, the front cover includes: a plate body, the plate body being disposed in the open portion at the front side of the main housing; a cover body, the cover body being disposed on the front side of the plate body and defining an accommodating space between the cover body and the plate body, the electrical control box being disposed in the accommodating space and connected to the plate body, and the second air inlet and the second air outlet being both opened on the plate body.

[0008] The above technical solution has the following advantages or beneficial effects: the accommodating space formed between the plate and the cover is connected to the interior of the main shell. In this way, the heat exchange airflow inside the main shell can flow into the accommodating space through the second air inlet, and the airflow in the accommodating space can flow into the main shell through the second air outlet, and then flow out of the outdoor unit of the air conditioner through the air outlet. This can dissipate heat from the electrical control box.

[0009] According to some embodiments of the present invention, a plane perpendicular to the vertical direction is defined as a horizontal plane, and the orthographic projection of the second air inlet on the horizontal plane and the orthographic projection of the third air inlet on the horizontal plane are at least partially offset from each other in the front-back direction.

[0010] The above technical solution has the following advantages or beneficial effects: Since the heat exchange airflow direction is from the second air inlet to the third air inlet, this can prevent water in the main shell from directly entering the electrical control box through the third air inlet. Thus, the staggered arrangement of the second and third air inlets can effectively block water from entering the electrical control box.

[0011] According to some embodiments of the present invention, the orthographic projection of the third air inlet on the horizontal plane is at least partially located in front of the orthographic projection of the second air inlet on the horizontal plane.

[0012] The above technical solution has the following advantages or beneficial effects: On the one hand, under the premise of ensuring that the second air inlet and the third air inlet are connected, the third air inlet and the second air inlet can be staggered as much as possible, which can improve the waterproof effect of the electrical control box. On the other hand, compared with the third air inlet, the second air inlet is closer to the heat exchange airflow of the main shell in the front-back direction, which helps to reduce the resistance of the heat exchange airflow from the main shell to the electrical control box and can ensure the flow of heat exchange airflow.

[0013] According to some embodiments of the present invention, the electrical control box is provided with an inclined wall surface, the inclined wall surface is inclined relative to the horizontal plane, and the third air inlet is opened on the inclined wall surface.

[0014] The above technical solution has the following advantages or beneficial effects: Under the premise of ensuring that the third air inlet is connected to the second air inlet, the third air inlet can be opened in the front-back direction to the side away from the second air inlet. In this way, even if water enters the containment space through the second air inlet during the operation of the outdoor unit of the air conditioner, it is difficult for water to enter the electrical control box through the third air inlet, which can further improve the waterproof performance of the electrical control box.

[0015] According to some embodiments of this utility model, a plane perpendicular to the front-back direction is defined as a vertical plane, and the orthographic projection of the second air outlet on the vertical plane and the orthographic projection of the third air outlet on the vertical plane are at least partially offset from each other in the vertical direction.

[0016] The above technical solution has the following advantages or beneficial effects: it can at least partially block the third air outlet, so that when the outdoor unit of the air conditioner is working, the panel can block water from passing through the third air outlet, thereby preventing water from splashing into the electrical control box through the second and third air outlets, and effectively improving the waterproof capability of the electrical control box.

[0017] According to some embodiments of the present invention, the orthographic projection of the third air outlet on the vertical plane is at least partially located above the orthographic projection of the second air outlet on the vertical plane.

[0018] The above technical solution has the following advantages or beneficial effects: the second air outlet is positioned below the third air outlet on the control box. In this way, even if water splashes inside the main housing and enters the containment space through the second air outlet, the water will move downwards under the action of gravity. Since the third air outlet is located above the second air outlet, it will be difficult for water entering the containment space through the second air outlet to enter the control box through the third air outlet. This effectively prevents water from entering the control box through the third air outlet and improves the waterproof capability of the control box.

[0019] According to some embodiments of the present invention, the orthographic projection of the second air outlet on the vertical plane is spaced below the orthographic projection of the outdoor fan on the vertical plane.

[0020] The above technical solution has the following advantages or beneficial effects: the heat exchange airflow in the accommodating space and the electrical control box flows into the main housing from the second air outlet. Setting the second air outlet at the lowest point of the outdoor fan on the plate can ensure that the heat exchange airflow in the accommodating space and the electrical control box flows into the main housing through the second air outlet, and together with the heat exchange airflow in the main housing, flows out from the air outlet at the top of the main housing under the action of the heat exchange fan.

[0021] According to some embodiments of this utility model, the electrical control box is provided with a horizontal wall and a vertical wall. The vertical wall extends in the vertical direction, and the third air outlet is disposed on the vertical wall. The horizontal wall extends in the front-back direction and its rear end is connected to the lower end of the vertical wall. The horizontal wall has a fourth air outlet, which is connected to the second air outlet. The above technical solution has the following advantages or beneficial effects: the horizontal wall is connected to the vertical wall, the fourth air outlet is set on the horizontal wall, and the third air outlet is set on the vertical wall. In this way, the area of ​​the air outlet can be increased above the electrical control box, which can increase the flow rate of heat exchange air from the electrical control box, thereby accelerating the heat dissipation of the electrical control box and improving the heat dissipation efficiency of the electrical control box.

[0022] According to some embodiments of the present invention, the electrical control box further includes a heat dissipation section, which passes through the plate and extends into the interior of the housing. The heat dissipation section is located below and adjacent to the second air outlet.

[0023] The above technical solution has the following advantages or beneficial effects: the heat dissipation part is used to dissipate the heat in the electrical control box, the heat exchange airflow inside the casing can flow through the heat dissipation part to carry away the heat on the heat dissipation part, and the air flowing out of the second air outlet partially carries away the heat on the heat dissipation part to improve the heat dissipation efficiency of the electrical control box.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0030] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0031] The following is based on Figures 1-10 This invention describes an embodiment of an air conditioner outdoor unit 100.

[0032] According to an embodiment of the present invention, the outdoor unit 100 of the air conditioner includes a casing 10, a compressor 20, an outdoor heat exchanger 30, and an outdoor fan 40. The casing 10 is provided with a first air inlet 11 and a first air outlet 12. Outdoor air enters the outdoor unit 100 of the air conditioner through the first air inlet 11. After entering the outdoor unit 100, the outdoor air can exchange heat with the outdoor heat exchanger 30 to change the temperature of the refrigerant in the outdoor heat exchanger 30.

[0033] According to an embodiment of the present invention, the outdoor unit 100 of the air conditioner further includes a refrigerant circulation loop, an outdoor fan 40, a power consumption sensor, and a controller.

[0034] In an embodiment of this utility model, the air conditioner includes an outdoor unit 100 and an indoor unit. The refrigerant circulation loop of the air conditioner consists of a compressor 20, a condenser, an expansion valve, and an evaporator. The refrigerant circulates between the compressor 20, the condenser, the expansion valve, and the evaporator, thereby forming a refrigerant circulation loop.

[0035] The compressor 20 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant. This heat can be exchanged with indoor air to heat the indoor air, or with outdoor air to cool the indoor air. In addition, the compressor 20 provides power for the circulation of the refrigerant.

[0036] One of the condensers and evaporator is the outdoor heat exchanger 30, and the other is the indoor heat exchanger. When the refrigerant enters the outdoor heat exchanger 30, it exchanges heat with the outdoor air. When the refrigerant enters the indoor heat exchanger, it exchanges heat with the indoor air.

[0037] When the air conditioner is in cooling mode, heat in the outdoor heat exchanger 30 is transferred from the refrigerant to the outdoor air, and heat in the indoor heat exchanger is transferred from the indoor air to the refrigerant. This allows the refrigerant to dissipate indoor heat to the outdoor environment, thereby lowering the indoor temperature.

[0038] When the air conditioner is in heating mode, heat is transferred from the outdoor air to the refrigerant in the outdoor heat exchanger 30, and heat is transferred from the refrigerant to the indoor air in the indoor heat exchanger. This allows the refrigerant to absorb heat from the outdoor environment and transfer the heat to the indoor environment, thereby raising the indoor temperature.

[0039] An expansion valve can change the pressure of the refrigerant in the refrigerant circulation loop. By throttling and reducing pressure, the expansion valve converts the medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, which then absorbs heat in the evaporator to achieve a cooling effect.

[0040] Furthermore, the expansion valve can automatically adjust the flow rate based on the superheat of the gaseous refrigerant at the evaporator outlet, maintaining a stable indoor temperature and meeting the requirements of refrigerant circulation. More importantly, the expansion valve can prevent liquid refrigerant from entering the compressor 20, avoiding liquid hammer and protecting the compressor 20 from damage.

[0041] The fan assembly is used to drive indoor air into the indoor unit of the air conditioner by rotation, and the air passes through the indoor heat exchanger to exchange heat between the refrigerant and the indoor air. The fan assembly accelerates the flow of indoor air to the indoor heat exchanger, thereby speeding up the heat exchange between the indoor air and the refrigerant.

[0042] The outdoor fan 40 is used to drive outdoor air through the outdoor heat exchanger 30 by rotation, so that the refrigerant and the outdoor air can exchange heat. Under the action of the outdoor fan 40, the flow of outdoor air to the outdoor heat exchanger 30 can be accelerated, thereby accelerating the heat exchange between the outdoor air and the refrigerant. Finally, the air that has undergone heat exchange can be blown into the room through the first air outlet 12.

[0043] A refrigerant pipe connects the outdoor heat exchanger 30 and the compressor 20. The refrigerant pipe is used to transfer the refrigerant between the compressor 20 and the outdoor heat exchanger 30, so as to realize the transfer of heat between the compressor 20 and the outdoor heat exchanger 30.

[0044] Furthermore, the outdoor unit 100 of the air conditioner also includes an electrical control box 50, which contains a control chip to realize the control function of the outdoor unit 100 of the air conditioner.

[0045] Furthermore, in the embodiments of this utility model, the outdoor unit 100 of the air conditioner includes, but is not limited to, a top-discharge type outdoor unit 100 of the air conditioner, with the first air inlet 11 disposed on the circumferential side wall of the casing 10 and the first air outlet 12 located at the top of the casing 10.

[0046] Specifically, when the outdoor unit 100 of the top-discharge air conditioner is running, under the action of the outdoor fan 40, outdoor air enters the outdoor unit 100 through the first air inlet 11 provided on the circumferential side wall of the casing 10. This allows the outdoor air to flow directly to the outdoor heat exchanger 30, so that the outdoor air can directly exchange heat with the outdoor heat exchanger 30. The outdoor heat exchanger 30 is arranged circumferentially along the inner wall of the casing 10. This makes the structural arrangement of the outdoor unit 100 more compact and helps to improve the space utilization rate inside the casing 10. With this arrangement, the flow path of outdoor air in the outdoor unit 100 is shorter, and the heat exchange is more sufficient, thereby improving the working efficiency of the outdoor unit 100.

[0047] Furthermore, the outdoor unit 100 of the air conditioner in this embodiment of the present invention also includes a maintenance panel and a refrigerant connector, wherein the refrigerant connector is disposed on the outside of the casing 10.

[0048] Specifically, the refrigerant connector is a key structure in the refrigerant circulation loop that connects the indoor unit and the outdoor unit 100 of the air conditioner. One end of the refrigerant connector is connected to the compressor 20, and the other end is connected to the indoor unit of the air conditioner. This allows the refrigerant to circulate between the outdoor unit 100 and the indoor unit of the air conditioner to achieve heat transfer and exchange.

[0049] According to an embodiment of the present invention, the housing 10 includes a main housing 13 and a front cover 14, wherein the front side of the main housing 13 is at least partially open, and the front cover 14 is disposed on the open portion of the front side of the main housing 13.

[0050] Specifically, in the embodiments of this utility model, the front side of the main housing 13 of the outdoor unit 100 of the air conditioner is connected to the front cover 14, and the front side of the main housing 13 is at least partially open, which is suitable for providing the front cover 14 on the front side of the main housing 13.

[0051] This design not only protects the front of the outdoor unit 100 of the air conditioner, but also ensures that the front cover 14 is reliably installed on the front of the outdoor unit 100 of the air conditioner, so that the front cover 14 provides stable and reliable support for other structural components installed on it, thereby improving the reliability of the outdoor unit 100 of the air conditioner.

[0052] Furthermore, the main housing 13 also includes a mesh cover that covers the air inlet on the main housing 13. This can filter the outdoor air entering the outdoor unit 100 of the air conditioner through the air inlet to reduce dust entering the outdoor unit 100 of the air conditioner. This can reduce dust accumulation inside the outdoor unit 100 of the air conditioner. In addition, the mesh cover also has the function of preventing rodents and insects, which can prevent large organisms from entering the outdoor unit 100 of the air conditioner and causing the outdoor fan 40 to jam or produce abnormal noise.

[0053] To facilitate cleaning of the mesh cover, during installation, the circumferential edge of the mesh cover is directly pressed onto the chassis and main housing 13.

[0054] Furthermore, the front cover 14 is installed over the open portion of the main housing 13, and the front cover 14 has an access port.

[0055] Specifically, the open portion of the main housing 13 can be used to pass through a refrigerant connector so that the end of the refrigerant connector away from the indoor unit of the air conditioner can be connected to the compressor 20.

[0056] Furthermore, the electrical control box 50 is located inside the front cover 14, so that the front cover 14 can protect the electrical control box 50 in the outdoor unit 100 of the air conditioner, thereby ensuring the structural safety and operational reliability of the electrical control box 50 and its internal electrical components.

[0057] Furthermore, the front cover 14 has a second air inlet 1411 and a second air outlet 1412 that communicate with the interior of the housing 10.

[0058] Specifically, in this way, the airflow inside the casing 10 can flow into the front cover 14 through the second air inlet 1411, and the airflow inside the casing 10 can also flow out of the casing 10 through the second air outlet 1412. This allows the heat exchange airflow in the outdoor unit 100 of the air conditioner to flow through the electrical control box 50 inside the front cover 14, so as to achieve air cooling of the electrical control box 50.

[0059] Furthermore, the electrical control box 50 has a third air inlet 511 and a third air outlet 521, the second air inlet 1411 and the third air inlet 511 are connected to each other, and the second air outlet 1412 and the third air outlet 521 are connected to each other.

[0060] Specifically, the heat exchange airflow outside the control box 50 can flow into the control box 50 through the third air inlet 511, and the airflow inside the control box 50 can flow out of the control box 50 through the third air outlet 521. This allows the airflow to flow inside the control box 50 and enables the control box 50 to be cooled by air.

[0061] Meanwhile, in the outdoor unit 100 of the air conditioner, when the heat exchange airflow flows into the control box 50, it first passes through the second air inlet 1411 and then through the third air inlet 511. The arrangement of the two air inlets can effectively prevent water from the outside of the control box 50 from splashing into the inside of the control box 50. When the heat exchange airflow flows out of the control box 50, it first passes through the third air outlet 521 and then through the second air outlet 1412. The arrangement of the two air outlets can effectively prevent water from the outside of the control box 50 from splashing into the inside of the control box 50.

[0062] Furthermore, the second air inlet 1411 and the third air inlet 511 are both downwardly open, and the second air outlet 1412 and the third air outlet 521 are both rearwardly open.

[0063] Specifically, in the outdoor unit 100 of the air conditioner, the air inlet is located below the air outlet. The heat exchange airflow flows from bottom to top under the action of the outdoor fan 40. The second air inlet 1411 and the third air inlet 511 are both open downwards. This allows the openings of the second air inlet 1411 and the third air inlet 511 to face the direction of the heat exchange airflow, thereby reducing the resistance of the heat exchange airflow when passing through the second air inlet 1411 and the third air inlet 511.

[0064] Furthermore, the second air outlet 1412 and the third air outlet 521 are both set to open upwards. This allows the heat exchange airflow inside the control box 50 to flow out of the control box 50 under the action of the outdoor fan 40 above, so as to remove the heat inside the control box 50. This enables the control box 50 to be cooled by air, ensuring that the control box 50 works normally in the outdoor unit 100 of the air conditioner.

[0065] Therefore, by providing corresponding air inlets and corresponding air outlets on the front cover 14 and the electrical control box 50, this embodiment of the utility model can effectively prevent water from splashing into the electrical control box 50, thereby enabling the electrical control box 50 of the outdoor unit 100 of the air conditioner to not only ventilate and dissipate heat, but also improve its waterproofness.

[0066] Combination Figure 3 As shown, the front cover 14 includes a plate 141 and a cover 142, wherein the plate 141 is disposed in the open portion on the front side of the main housing 13.

[0067] Specifically, the front cover 14 is located on the front side of the main housing 13. The plate 141 of the front cover 14 is located in the open portion on the front side of the main housing 13 to cover the front side of the main housing 13. This can prevent air leakage on the front side of the main housing 13 and ensure the structural integrity of the outdoor unit 100 of the air conditioner.

[0068] Furthermore, the cover 142 is placed on the front side of the plate 141 and defines an accommodating space 143 between the cover 142 and the plate 141. In this way, the electrical control box 50 is placed in the accommodating space 143 and connected to the plate 141. This not only ensures the stability of the electrical control box 50 in the outdoor unit 100 of the air conditioner, but also allows the cover 142 to protect the electrical control box 50, preventing water and dust from entering the electrical control box 50. This ensures the normal operation of the electrical control box 50.

[0069] Furthermore, the second air inlet 1411 and the second air outlet 1412 are both located on the plate 141. This arrangement allows the accommodating space 143 formed between the plate 141 and the cover 142 to communicate with the interior of the main housing 13. In this way, the heat exchange airflow inside the main housing 13 can flow into the accommodating space 143 through the second air inlet 1411, and the airflow in the accommodating space 143 can flow into the main housing 13 through the second air outlet 1412, and then flow out of the outdoor unit 100 of the air conditioner through the air outlet. This can dissipate heat from the electrical control box 50.

[0070] Combination Figure 6 , Figure 7 and Figure 8As shown, the plane perpendicular to the vertical direction is defined as the horizontal plane, and the orthographic projection of the second air inlet 1411 on the horizontal plane and the orthographic projection of the third air inlet 511 on the horizontal plane are at least partially offset from each other in the front-back direction.

[0071] Specifically, in this embodiment of the present invention, the second air inlet 1411 is located at the bottom of the cover, and the third air inlet 511 is located at the bottom of the electrical control box 50. The orthographic projections of the second air inlet 1411 and the third air inlet 511 on the horizontal plane are at least partially offset from each other. This can prevent water in the main housing 13 from directly entering the electrical control box 50 through the third air inlet 511. Thus, the offset arrangement of the second air inlet 1411 and the third air inlet 511 can effectively block water from entering the electrical control box 50.

[0072] Combination Figure 7 and Figure 8 As shown, the orthographic projection of the third air inlet 511 on the horizontal plane is at least partially located in front of the orthographic projection of the second air inlet 1411 on the horizontal plane.

[0073] Specifically, in the embodiment of the utility model, the third air inlet 511 is located in front of the second air inlet 1411. This arrangement serves two purposes: firstly, while ensuring that the second air inlet 1411 and the third air inlet 511 are connected, the third air inlet 511 and the second air inlet 1411 can be staggered as much as possible to improve the waterproof effect of the electrical control box 50; secondly, compared to the third air inlet 511, the second air inlet 1411 is closer to the heat exchange airflow of the main housing 13 in the front-back direction. This helps to reduce the resistance of the heat exchange airflow from the main housing 13 to the electrical control box 50 and can ensure the flow of the heat exchange airflow.

[0074] Combination Figure 8 As shown, the electrical control box 50 is provided with an inclined wall 51, which is inclined relative to the horizontal plane, and the third air inlet 511 is opened on the inclined wall 51.

[0075] Specifically, the third air inlet 511 is set on the inclined surface of the electrical control box 50, which is inclined relative to the horizontal plane. This allows the third air inlet 511 to be inclined relative to the second air inlet 1411, and the third air inlet 511 to be inclined toward the side away from the second air inlet 1411. In this way, while ensuring that the third air inlet 511 and the second air inlet 1411 are connected, the third air inlet 511 can be opened in the front-back direction toward the side away from the second air inlet 1411.

[0076] In this way, even if water enters the containment space 143 through the second air inlet 1411 during the operation of the outdoor unit 100 of the air conditioner, it is difficult for water to enter the electrical control box 50 through the third air inlet 511, which can further improve the waterproof performance of the electrical control box 50.

[0077] Combination Figure 6 , Figure 7 and Figure 9 As shown, the plane perpendicular to the front-back direction is defined as the vertical plane, and the orthographic projection of the second air outlet 1412 on the vertical plane and the orthographic projection of the third air outlet 521 on the vertical plane are at least partially offset from each other in the vertical direction.

[0078] Specifically, in the embodiments of this utility model, the second air outlet 1412 and the third air outlet 521 are staggered in the vertical direction. This not only allows the second air outlet 1412 to be positioned adjacent to the third air outlet 521 so that the third air outlet 521 and the second air outlet 1412 are correspondingly connected, ensuring that the heat exchange airflow in the electrical control box 50 can smoothly flow out of the accommodating space 143 through the third air outlet 521 and the second air outlet 1412 to remove the heat in the electrical control box 50, but also avoids the third air outlet 521 and the second air outlet 1412 being completely corresponding in the vertical direction.

[0079] This configuration allows the panel 141 to at least partially block the third air outlet 521. When the outdoor unit 100 of the air conditioner is working, the panel 141 can block water from passing through the third air outlet 521, thereby preventing water from splashing into the electrical control box 50 through the second air outlet 1412 and the third air outlet 521, which can effectively improve the waterproof capability of the electrical control box 50.

[0080] Combination Figure 6 , Figure 7 and Figure 9 As shown, the orthographic projection of the third air outlet 521 on the vertical plane is at least partially located above the orthographic projection of the second air outlet 1412 on the vertical plane.

[0081] Specifically, in the embodiments of this utility model, the third air outlet 521 is located above the box body of the electrical control box 50, and the second air outlet 1412 is located on the plate 141 below the position of the third air outlet 521 on the electrical control box 50.

[0082] In this way, even if water splashes inside the main housing 13 and enters the receiving space 143 through the second air outlet 1412, the water moves downward under the action of gravity. Since the third air outlet 521 is located above the second air outlet 1412, it will be difficult for the water entering the receiving space 143 through the second air outlet 1412 to enter the electrical control box 50 through the third air outlet 521. This can effectively prevent water from entering the electrical control box 50 through the third air outlet 521 and improve the waterproof capability of the electrical control box 50.

[0083] Combination Figure 6 , Figure 7 and Figure 9 As shown, the orthographic projection of the second air outlet 1412 on the vertical plane is spaced below the orthographic projection of the outdoor fan 40 on the vertical plane.

[0084] Specifically, in this embodiment of the present invention, the outdoor fan 40 is located at the top of the outdoor unit 100 of the air conditioner near the air outlet. Under the action of the outdoor fan 40, outdoor air enters the main housing 13 through the air inlet, then flows upward, and finally flows out of the outdoor unit 100 of the air conditioner from the air outlet at the top of the main housing 13.

[0085] Furthermore, the heat exchange airflow in the accommodating space 143 and the electrical control box 50 both flow into the main housing 13 through the second air outlet 1412. By setting the second air outlet 1412 on the plate 141 at the lowest point corresponding to the outdoor fan 40, it can be ensured that the heat exchange airflow in the accommodating space 143 and the electrical control box 50 both flow into the main housing 13 through the second air outlet 1412, and together with the heat exchange airflow in the main housing 13, they flow out from the air outlet at the top of the main housing 13 under the action of the heat exchange fan.

[0086] Combination Figure 6 , Figure 7 and Figure 10 As shown, the electrical control box 50 is provided with a horizontal wall 53 and a vertical wall 52. The vertical wall 52 extends in the vertical direction, and the third air outlet 521 is provided on the vertical wall 52. The horizontal wall 53 extends in the front-back direction and its rear end is connected to the lower end of the vertical wall 52. The horizontal wall 53 is provided with a fourth air outlet 531, which is connected to the second air outlet 1412.

[0087] Specifically, a third air outlet 521 is opened on the vertical wall 52 of the electrical control box 50, and a fourth air outlet 531 is opened on the horizontal wall 53 connected to the lower end of the vertical wall 52. The horizontal wall 53 is connected to the vertical wall 52. In this way, the area of ​​the air outlets above the box body of the electrical control box 50 can be increased, which can increase the flow rate of heat exchange air from the electrical control box 50, thereby accelerating the heat dissipation of the electrical control box 50 and improving the heat dissipation efficiency of the electrical control box 50.

[0088] Combination Figure 3 , Figure 7 and Figure 9 As shown, the electrical control box 50 also includes a heat dissipation section 54, which passes through the plate 141 and extends into the interior of the housing 10.

[0089] Specifically, the heat dissipation part 54 is used to dissipate the heat in the control box 50. The heat dissipation part 54 on the control box 50 passes through the plate 141 and extends into the housing 10. In this way, the heat exchange airflow inside the housing 10 can flow through the heat dissipation part 54 to carry away the heat on the heat dissipation part 54 and exhaust it to the outside through the air outlet at the top of the outdoor unit 100 of the air conditioner. This can achieve air cooling of the control box 50.

[0090] Furthermore, the heat dissipation unit 54 is located below and adjacent to the second air outlet 1412.

[0091] Specifically, the heat dissipation part 54 passes through the plate 141 and is located below the second air outlet 1412. This allows the heat dissipation part 54 to avoid the second air outlet 1412, so that the air flowing out from the second air outlet 1412 can flow directly to the air outlet. This ensures the heat dissipation efficiency of the electrical control box 50 and reduces the generation of turbulence in the main housing 13.

[0092] Furthermore, the heat dissipation unit 54 is disposed adjacent to the second air outlet 1412, so that the air flowing out of the second air outlet 1412 can partially carry away the heat on the heat dissipation unit 54, thereby improving the heat dissipation efficiency of the electrical control box 50.
