[0039] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0040] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0041] Please refer to the following Figure 1-Figure 10 An air conditioner outdoor unit 100 according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, the outdoor unit 100 of the air conditioner according to the embodiment of the utility model includes a casing 10, an outdoor heat exchanger, an outdoor fan assembly 20 and an electric control box 30.

[0043] The casing 10 is arranged in an outdoor environment, so that outdoor air can enter the casing 10, which is convenient for the outdoor air to exchange heat with the outdoor heat exchanger. The casing 10 is provided with an air inlet and an air outlet. The outdoor heat exchanger is arranged in the casing 10. The outdoor fan assembly 20 is arranged in the casing 10 and is located on one side of the outdoor heat exchanger. The outdoor fan assembly 20 drives the outdoor air to enter the casing 10 from the air inlet, and the outdoor air exchanges heat with the outdoor heat exchanger to form a heat exchange airflow, and then is driven by the fan assembly to flow out of the casing 10 from the air outlet.

[0044] In this way, the air conditioner outdoor unit 100 can selectively control the outdoor air to enter the casing 10 through the air inlet, and the outdoor air can form a heat exchange airflow after heat exchange with the outdoor heat exchanger, and then be driven by the fan assembly to flow out of the casing 10 from the air outlet, thereby realizing indoor cooling or heating.

[0045] The electric control box 30 is disposed in the housing 10 , and the housing 10 can protect the electric control box 30 to prevent outdoor dust and rainwater from entering the electric control box 30 , thereby ensuring the working safety of the electric control box 30 .

[0046] Combination Figure 2-Figure 12 As shown, the electric control box 30 includes a box body 31 , a heat sink 32 and a control circuit board 33 .

[0047] There are heat dissipation holes 311 on one side of the box body 31 in the first direction. This is because the electric control box 30 generates heat during operation. If the electric control box 30 is not dissipated in time, the heat accumulated in the electric control box 30 is too high, which will cause the electrical components 332 in the electric control box 30 to fail due to heat. In more serious cases, the electrical components 332 will burn out, causing damage to the air conditioner outdoor unit 100.

[0048] It can be understood that the heat dissipation holes 311 are provided on the electric control box 30 to ensure that the air inside the electric control box 30 and the air outside the electric control box 30 circulate with each other, so that the heat inside the electric control box 30 can be dissipated to the outside of the electric control box 30 along with the flow of air, thereby reducing the heat inside the electric control box 30 and lowering the temperature inside the electric control box 30, so as to prevent the electrical components 332 inside the electric control box 30 from accumulating too much heat and failing or even burning.

[0049] It is understandable that when the electric control box 30 is provided with the heat dissipation holes 311, the air inside the electric control box 30 and the air outside the electric control box 30 can circulate with each other. However, on rainy days, water outside the electric control box 30 can enter the inside of the electric control box 30 through the heat dissipation holes 311.

[0050] When rainwater enters the electric control box 30 through the heat dissipation holes 311, the rainwater will splash onto the electric control box 30, thereby causing the electric control box 30 to burn. To ensure the working safety of the electric control box 30, it is necessary to prevent rainwater from entering the electric control box 30 while ensuring the heat dissipation of the electric control box 30.

[0051] The heat dissipation hole 311 is provided with a water retaining rib 312, which can partially cover the heat dissipation hole 311, but will not completely block the circulation of air. When air flows through the water retaining rib 312, rainwater will not directly enter the interior of the electric control box 30, but will be mostly blocked by the water retaining rib 312. This arrangement can prevent rainwater from entering the electric control box 30.

[0052] The control circuit board 33 is arranged in the box body 31 , so that the box body 31 of the electric control box 30 can protect the control circuit board 33 and prevent outdoor dust, rain and other substances from affecting the normal operation of the control circuit board 33 .

[0053] The control circuit board 33 is spaced apart and arranged on one side of the radiator 32 in the first direction away from the water retaining rib 312. Such arrangement not only enables the radiator 32 to quickly transfer the heat on the control circuit board 33 to the electric control box 30, but also enables the control circuit board 33 to be arranged away from the heat dissipation hole 311, thereby further preventing rainwater outside the electric control box 30 from splashing onto the control circuit board 33.

[0054] However, during the rain test under the simulated storm condition, the external wind volume is too large, which causes the fan in the outdoor fan assembly 20 to reverse. At this time, the wind field around the electric control box 30 is more complicated, and a small amount of rainwater will still enter through the water retaining rib 312 and then through the fins of the radiator 32, and then enter the electric control box 30. Under the effect of the fan reversal, rainwater will splash onto the control circuit board 33 inside the electric control box 30, which will still cause the control circuit board 33 to burn out.

[0055] In an embodiment of the utility model, the electric control box 30 further includes a water baffle 34 , which is disposed in the box body 31 . The water baffle 34 can be used to prevent rainwater from splashing onto the control circuit board 33 in the electric control box 30 .

[0056] Furthermore, the water retaining plate 34 includes a first plate body 341 , the first plate body 341 is connected to a side of the radiator 32 away from the water retaining rib 312 in the first direction, and the first plate body 341 is extended in the first direction.

[0057] Specifically, in order to ensure the heat dissipation effect of the electric control box 30, the radiator 32 is arranged near the heat dissipation hole 311, and the first plate body 341 is connected to the side of the radiator 32 in the first direction away from the water retaining rib 312, that is, the radiator 32 is arranged between the first plate body 341 and the heat dissipation hole 311. In this way, the first plate body 341 can be arranged closer to the control circuit board 33, which can enhance the protection effect of the water retaining plate 34 on the control circuit board 33.

[0058] In addition, the first plate body 341 is connected to the radiator 32, and the first plate body 341 is extended in the first direction. This not only allows the first plate body 341 to extend toward the control circuit board 33 and the water baffle 34 to be close to the control circuit board 33, but also ensures the structural reliability and stability of the first plate body 341 between the radiator 32 and the control circuit board 33, thereby ensuring the water-blocking effect of the water baffle 34.

[0059] The water baffle 34 includes a second plate body 342, which is connected to one end of the first plate body 341 away from the radiator 32 in the first direction, and the second plate body 342 extends toward one side in the second direction. The second plate body 342 is located between the control circuit board 33 and the radiator 32 in the first direction, wherein the first direction and the second direction are perpendicular to each other.

[0060] Specifically, the second plate 342 is disposed closer to the control circuit board 33 than the first plate 341 to prevent rainwater from splashing onto the control circuit board 33. The second plate 342 is connected to the first plate 341 to ensure the position stability and structural reliability of the second plate 342 in the electric control box 30.

[0061] The second plate body 342 extends in the second direction, and the second direction is perpendicular to the first direction. This can increase the water blocking area of ​​the water baffle plate 34 for the control circuit board 33, improve the water blocking reliability of the water baffle plate 34, and effectively prevent rainwater from splashing onto the control circuit board 33 from the heat dissipation hole 311 along the first direction.

[0062] Therefore, by setting a water retaining plate 34 between the radiator 32 and the control circuit board 33, after rainwater enters the electrical control box 30 through the water retaining rib 312, it can effectively prevent water from splashing onto the control circuit board 33, and can prevent the control circuit board 33 from burning, thereby improving the safety of the air conditioner outdoor unit 100.

[0063] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6 and Fig.11 As shown, the control circuit board 33 includes a board body 331 and electrical components 332 .

[0064] The plate member 331 is a whole and can be used to arrange a plurality of electrical components 332. The plate member 331 is arranged at intervals on one side of the second direction of the heat sink 32. In the embodiment of the utility model, the plate member 331 and the heat sink 32 at least partially overlap in the first direction, so that the heat on the plate member 331 can be directly transferred to the heat sink 32, so that the heat in the control circuit board 33 can be transferred out through the heat sink 32, so as to accelerate the heat dissipation efficiency of the control circuit board 33.

[0065] A plurality of electrical components 332 are arranged on one side of the plate body 331 in the second direction, and are extended in the second direction, so that part of the plurality of electrical components 332 can correspond to the radiator 32, which not only allows the heat generated by this part of the electrical components 332 to be directly transferred to the radiator 32, which is beneficial to accelerate the heat dissipation of this part of the electrical components 332, but also saves the layout space of the control circuit board 33 while ensuring the structural integrity of the control circuit board 33, and can improve the compactness of the structure inside the electric control box 30.

[0066] It is understandable that the multiple electrical components 332 also include larger electrical components 332. If the larger electrical components 332 are arranged at a position corresponding to the heat sink 32 in the second direction of the plate body 331, the distance between the plate body 331 and the heat sink 32 will increase, which will increase the size of the control circuit board 33 in the second direction, and further increase the size of the electrical control box 30, which is not conducive to the arrangement of the electrical control box 30 in the casing 10.

[0067] Therefore, at least some of the multiple electrical components 332 are spaced apart on one side of the radiator 32 away from the water retaining rib 312 in the first direction, so that the larger electrical components 332 among the multiple electrical components 332 can avoid the arrangement of the radiator 32, thereby facilitating the improvement of the compactness of the structure inside the electrical control box 30.

[0068] In the embodiment of the present utility model, combined with Figure 5 As shown, the electrical components 332 closer to the water retaining plate 34 include but are not limited to the electrolytic capacitor 3321, the capacitor 3322 and the wiring harness 3323. The water retaining plate 34 can shield the electrical components 332 closer to the position thereof, and can prevent water from splashing to the electrolytic capacitor 3321, the capacitor 3322 and the wiring harness 3323. According to the test, the electrical components 332 on the plate body 331 that are farther from the water retaining plate 34 do not need to be shielded.

[0069] The first plate 341 is spaced apart from the electrical device 332 in the first direction, and the first plate 341 is spaced apart from the plate member 331 in the second direction, so that the first plate 341 can avoid the arrangement of the electrical device 332 on the plate member 331. The second plate 342 is extended toward a side away from the plate member 331 in the second direction, so that the shielding area of ​​the second plate 342 on the control circuit board 33 in the second direction can be increased.

[0070] It can be understood that the larger electrical component 332 extends along the second direction on the plate body 331, and the extension direction of the second plate body 342 in the second direction is the same as the extension direction of the larger electrical component 332 in the second direction, so that the second plate body 342 can shield the larger electrical component 332, thereby improving the water-blocking reliability of the water baffle plate 34 for the control circuit board 33.

[0071] In some embodiments of the present invention, Figure 7 and Figure 8 , Fig.11 and Fig.12 As shown, the water baffle 34 also includes a third plate body 343, one end of which is connected to a side of the radiator 32 away from the water baffle 312 in the first direction, so that the third plate body 343 can be arranged between the radiator 32 and the control circuit board 33, thereby preventing the water baffle 34 from blocking the heat dissipation hole 311 and ensuring air circulation at the heat dissipation hole 311.

[0072] One end of the third plate body 343 is connected to an end of the radiator 32 that is closer to the plate body part 331 in the second direction. In this way, the third plate body 343 can be arranged close to the plate body part 331 in the second direction, which can not only ensure the structural reliability of the water baffle plate 34 in the electrical control box 30, but also help to increase the size of the water baffle plate 34 in the second direction, thereby increasing the water-blocking area of ​​the water baffle plate 34, which is beneficial to improving the water-blocking effect of the water baffle plate 34.

[0073] The third plate body 343 is extended toward a side away from the plate body member 331 in the second direction, so that the water baffle plate 34 can be extended in the second direction to increase the size of the water baffle plate 34 in the second direction.

[0074] The distance between the third plate body 343 and the radiator 32 gradually increases in the second direction away from the plate body 331, so that a heat dissipation space can be left between the third plate body 343 and the radiator 32, which is beneficial to air flow and can increase the contact area between the fins of the radiator 32 and the air, thereby facilitating the improvement of the heat dissipation efficiency of the radiator 32.

[0075] The first plate 341 is connected to one end of the third plate 343 in the second direction away from the plate member 331, so that the first plate 341 can be fixed on the third plate 343. In this way, the first plate 341 can maintain an unchanged position relative to the radiator 32, thereby ensuring the structural reliability of the first plate 341 between the radiator 32 and the control circuit board 33.

[0076] In some embodiments of the present invention, Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.12 As shown, the water retaining plate 34 also includes a fourth plate body 344, which is arranged on a side of the radiator 32 that is further away from the water retaining rib 312 in the first direction and is connected to the fourth plate body 344 and an end of the radiator 32 that is closer to the plate body member 331 in the second direction. They are fitted together and connected to each other.

[0077] Specifically, the fourth plate body 344 is the contact portion between the water baffle plate 34 and the radiator 32. This arrangement can not only ensure that the fourth plate body 344 is arranged between the radiator 32 and the control circuit board 33, but also increase the contact area between the fourth plate body 344 and the radiator 32 in the second direction, thereby improving the connection reliability between the water baffle plate 34 and the radiator 32, and ensuring the water-blocking reliability of the water baffle plate 34 for the control circuit board 33.

[0078] Furthermore, the third plate body 343 is connected to the side of the fourth plate body 344 away from the plate body member 331 in the second direction, so that the third plate body 343 is connected to the fourth plate body 344. In this way, the second direction of the water retaining plate 34 is sequentially set as the fourth plate body 344, the third plate body 343, the first plate body 341 and the second plate body 342 from the side of the radiator 32 away from the water retaining rib 312.

[0079] In some embodiments of the present invention, Fig.12 As shown, the fourth plate 344 , the third plate 343 and the first plate 341 together define an escape space 40 , and the escape space 40 is used to escape at least part of the plurality of electrical components 332 .

[0080] Specifically, the fourth plate body 344 and the third plate body 343 both extend toward the same side of the second direction, and the first plate body 341 extends along the first direction. In this way, an avoidance space 40 can be defined between the radiator 32 and the control circuit board 33 toward the plate body member 331, so that the water baffle 34 can avoid the setting of some electrical components 332 on the plate body member 331, so as to facilitate the arrangement of multiple electrical components 332 on the plate body member 331.

[0081] Furthermore, the fourth plate 344, the third plate 343 and the first plate 341 can jointly shield the avoidance space 40 to prevent rainwater from passing through the fins of the radiator 32 and splashing onto the electrical components 332 in the avoidance space 40, thereby ensuring the safety of the electrical components 332 in the avoidance space 40.

[0082] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.12 As shown, a first through hole 3441 is provided on the fourth plate 344 , and a second through hole 321 is provided on the heat sink 32 . The first through hole 3441 and the second through hole 321 correspond to each other and are connected and fixed by a fastener 60 .

[0083] Specifically, the structures of the first through hole 3441 and the second through hole 321 are relatively simple, and are easy to process during the production process of the air conditioner outdoor unit 100. The first through hole 3441 is located on the fourth plate 344, and the second through hole 321 is located on the radiator 32.

[0084] With such arrangement, the fastener 60 can be used to pass through the first through hole 3441 and the second through hole 321 in sequence, and then the fastener 60 can be tightened, so that the fourth plate body 344 can be connected and fixed to the radiator 32, thereby fixing the water baffle 34 to the radiator 32.

[0085] Furthermore, when installing the water baffle 34 and the radiator 32, after the fourth perforation 3441 and the radiator 32 are fitted together and the fourth plate body 344 is moved to a suitable position, the first perforation 3441 and the second perforation 321 can correspond to each other, so that the fastener 60 can pass through the first perforation 3441 and the second perforation 321 in sequence, which can improve the assembly convenience of the water baffle 34 and the radiator 32.

[0086] In some embodiments of the present invention, Figure 8 and Fig.11 As shown, the size of the third plate body 343 in the third direction is smaller than the size of the fourth plate body 344 in the third direction, so that a heat dissipation vent 50 can be formed between the third plate body 343 and the fourth plate body 344 in the third direction, so that air can pass through the heat dissipation vent 50, which can enhance the flow of the wind field between the water baffle plate 34 and the radiator 32, and is beneficial to enhance the heat dissipation effect of the radiator 32.

[0087] According to some embodiments of the utility model, the size of the first plate body 341 in the third direction is smaller than the size of the third plate body 343 in the third direction, so that a heat dissipation passage 50 can be formed between the first plate body 341 and the third plate body 343 in the third direction to increase the air circulation rate between the first plate body 341 and the radiator 32. This can improve the flow of the wind field between the water baffle 34 and the radiator 32, which is beneficial to improving the heat dissipation effect of the radiator 32.

[0088] According to other embodiments of the present invention, the size of the second plate body 342 in the third direction is smaller than the size of the third plate body 343 in the third direction, so that a heat dissipation vent 50 can be formed between the second plate body 342 and the third plate body 343 in the third direction to increase the air circulation rate between the second plate body 342 and the radiator 32. This can improve the flow of the wind field between the water baffle 34 and the radiator 32, which is beneficial to improving the heat dissipation effect of the radiator 32.

[0089] According to some other embodiments of the utility model, the size of the first plate 341 in the third direction is smaller than the size of the third plate 343 in the third direction, and the size of the second plate 342 in the third direction is smaller than the size of the third plate 343 in the third direction. In this way, the area of ​​the heat dissipation opening 50 on the water baffle 34 can be increased, and the air circulation rate between the water baffle 34 and the radiator 32 can be further increased, thereby improving the flow of the wind field between the water baffle 34 and the radiator 32, which is conducive to improving the heat dissipation effect of the radiator 32.

[0090] In some specific embodiments of the present invention, a distance between an edge of the second plate 342 away from the first plate 341 in the second direction and a side of the box body 31 adjacent to the electrical device 332 in the second direction is L1, 1 mm < L1.

[0091] That is to say, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction cannot be too small. If the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is too small, it will affect the air flow between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction. The air flow between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is reduced, and the heat dissipation effect is poor. Therefore, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is not less than 1 mm.

[0092] Preferably, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is not less than 1.4 mm, so that the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction can be larger, and the air flow between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction can be larger.

[0093] Further preferably, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is not less than 1.8 mm, so that the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction can be larger, the air flow between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction can be larger, the heat dissipation effect of the radiator 32 can be better, and then the heat dissipation effect of the electric control box 30 can be better, which can effectively prevent excessive heat from accumulating in the electric control box 30, thereby improving the working safety of the electric control box 30.

[0094] In some specific embodiments of the present invention, a distance between an edge of the second plate 342 away from the first plate 341 in the second direction and a side of the box body 31 adjacent to the electrical device 332 in the second direction is L1, and L1<3 mm.

[0095] That is to say, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction cannot be too large. If the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is too large, the possibility of rain splashing onto the electrical device 332 will also increase accordingly, and the shielding range of the water retaining plate 34 for rain in a storm will be reduced, the shielding effect will be worse, and the possibility of the control circuit board 33 being burned will also be greater. Therefore, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is not greater than 3 mm.

[0096] Preferably, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is no more than 2.6 mm. In this way, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction can be smaller, the shielding range of the water retaining plate 34 is increased, the possibility of rainwater splashing onto the electrical device 332 is reduced, and the working safety of the control circuit board 33 is improved.

[0097] Further preferably, the distance between the side edge of the second plate body 342 away from the first plate body 341 in the second direction and the side of the box body 31 adjacent to the electrical device 332 in the second direction is not greater than 2.2 mm.

[0126] In some specific embodiments of the present application, the first direction, the second direction and the third direction are perpendicular to each other.

[0127] like Figure 2-Figure 12 As shown, the outdoor unit 100 of the air conditioner according to the embodiment of the utility model includes a casing 10, an outdoor heat exchanger, an outdoor fan assembly 20 and an electric control box 30.

[0128] The casing 10 is arranged in an outdoor environment, so that outdoor air can enter the casing 10, which is convenient for the outdoor air to exchange heat with the outdoor heat exchanger. The casing 10 is provided with an air inlet and an air outlet. The outdoor heat exchanger is arranged in the casing 10. The outdoor fan assembly 20 is arranged in the casing 10 and is located on one side of the outdoor heat exchanger. The outdoor fan assembly 20 drives the outdoor air to enter the casing 10 from the air inlet, and the outdoor air exchanges heat with the outdoor heat exchanger to form a heat exchange airflow, and then is driven by the fan assembly to flow out of the casing 10 from the air outlet.

[0129] The casing 10 may have multiple air inlets, for example, one air inlet is for outdoor heat exchange airflow, and another air inlet is for fresh air. In addition, the outdoor fan assembly 20 may be located on one side of the outdoor heat exchanger adjacent to the air outlet.

[0130] In this way, the air conditioner outdoor unit 100 can selectively control the outdoor air to enter the casing 10 through multiple air inlets, and the outdoor air can form a heat exchange airflow after heat exchange with the outdoor heat exchanger, or be driven by the fan assembly to be introduced into the room from the air outlet, thereby realizing indoor cooling, heating or fresh air.

[0131] The electric control box 30 is disposed in the housing 10 , and the housing 10 can protect the electric control box 30 to prevent outdoor dust and rainwater from entering the electric control box 30 , thereby ensuring the working safety of the electric control box 30 .

[0132] It is understandable that the electric control box 30 can control the working state of the outdoor heat exchanger and the outdoor fan assembly 20 so that the outdoor heat exchanger and the outdoor fan assembly 20 are suitable for corresponding operation under different working conditions of the air conditioner outdoor unit 100.

[0133] Combination Figure 2 As shown, the electric control box 30 includes a box body 31 , a heat sink 32 and a control circuit board 33 .

[0134] There are heat dissipation holes 311 on one side of the box body 31 in the first direction. This is because the electric control box 30 generates heat during operation. If the electric control box 30 is not dissipated in time, the heat accumulated in the electric control box 30 is too high, which will cause the electrical components 332 in the electric control box 30 to fail due to heat. In more serious cases, the electrical components 332 will burn out, causing damage to the air conditioner outdoor unit 100.

[0135] It can be understood that the heat dissipation holes 311 are provided on the electric control box 30 to ensure that the air inside the electric control box 30 and the air outside the electric control box 30 circulate with each other, so that the heat inside the electric control box 30 can be dissipated to the outside of the electric control box 30 along with the flow of air, thereby reducing the heat inside the electric control box 30 and lowering the temperature inside the electric control box 30, so as to prevent the electrical components 332 inside the electric control box 30 from accumulating too much heat and failing or even burning.

[0136] It is understandable that when the heat dissipation holes 311 are provided on the electric control box 30, the air inside the electric control box 30 and the air outside the electric control box 30 can circulate with each other, and the water outside the electric control box 30 can enter the electric control box 30 through the heat dissipation holes 311, especially in a rainy environment.

[0137] When rainwater enters the electric control box 30 through the heat dissipation holes 311, the rainwater will splash onto the electric control box 30, thereby causing the electric control box 30 to burn. To ensure the working safety of the electric control box 30, it is necessary to prevent rainwater from entering the electric control box 30 while ensuring the heat dissipation of the electric control box 30.

[0138] The heat dissipation hole 311 is provided with a water retaining rib 312, which can partially cover the heat dissipation hole 311, but will not completely block the circulation of air. When air flows through the water retaining rib 312, the wind field of the air here will be disturbed by the water retaining rib 312, so that rainwater will not directly enter the inside of the electric control box 30, but will be mostly blocked by the water retaining rib 312. In this way, most rainwater can be blocked from entering the electric control box 30.

[0139] The control circuit board 33 is arranged in the box body 31 , so that the box body 31 of the electric control box 30 can protect the control circuit board 33 and prevent outdoor dust, rain and other substances from affecting the normal operation of the control circuit board 33 .

[0140] The control circuit board 33 is spaced apart and arranged on one side of the radiator 32 in the first direction away from the water retaining rib 312. Such arrangement not only enables the radiator 32 to quickly transfer the heat on the control circuit board 33 to the electric control box 30, but also enables the control circuit board 33 to be arranged away from the heat dissipation hole 311, thereby further preventing rainwater outside the electric control box 30 from splashing onto the control circuit board 33.

[0141] However, in the rain test under the simulated storm condition, the external wind volume is too large, which causes the fan in the outdoor fan assembly 20 to reverse. At this time, the wind field around the electric control box 30 is more complicated, and a small amount of rainwater still enters through the water retaining rib 312 and then through the fins of the radiator 32, and then enters the electric control box 30. Under the effect of the fan reversal, rainwater may splash onto the control circuit board 33 inside the electric control box 30, which may still cause the control circuit board 33 to burn out.

[0142] In an embodiment of the utility model, the electric control box 30 further includes a water baffle 34 , which is disposed in the box body 31 . The water baffle 34 can be used to prevent rainwater from splashing onto the control circuit board 33 in the electric control box 30 .

[0143] Furthermore, the water retaining plate 34 is connected to a side of the radiator 32 in the first direction away from the water retaining rib 312 .

[0144] Specifically, in order to ensure the heat dissipation effect of the electric control box 30, the radiator 32 is arranged near the heat dissipation hole 311, and the water baffle 34 is connected to the side of the radiator 32 in the first direction away from the water baffle 312. That is, in the first direction, the radiator 32 is arranged between the water baffle 34 and the heat dissipation hole 311, and the water baffle 34 is arranged between the radiator 32 and the control circuit board 33. In this way, the water baffle 34 can be arranged close to the control circuit board 33, so that the water baffle 34 can have a water-blocking effect on the control circuit board 33, which can prevent rainwater outside the electric control box 30 from entering the inside of the electric control box 30 through the heat dissipation hole 311 and then splashing onto the control circuit board 33 through the fins of the radiator 32, which can prevent the control circuit board 33 from burning, thereby improving the safety of the air conditioner outdoor unit 100.

[0145] Other structures and operations of the air conditioner outdoor unit 100 according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0146] The air conditioner outdoor unit 100 of the present invention performs a refrigeration cycle of the air conditioner outdoor unit 100 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0147] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0148] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner outdoor unit 100 can adjust the temperature and humidity of the indoor space.
