[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following is for reference. Figures 1-14 The electronic control component 10 according to a first aspect embodiment of the present invention is described.

[0047] like Figures 6-14 As shown, the electronic control assembly 10 according to the first aspect of the present invention includes: an electronic control box 11 and an electronic control unit 12.

[0048] Specifically, the control box 11 has a receiving cavity 111, the control unit 12 is disposed in the receiving cavity 111, and the control box 11 has a first air inlet 13 and an air outlet 14 communicating with the receiving cavity 111. The control unit 12 is located between the first air inlet 13 and the air outlet 14, and the first air inlet 13 and the control unit 12 are connected in a first direction (e.g., in the first direction). Figure 8 The air inlet 13 is provided with an air guide 131 at intervals in the left and right directions shown in the figure. In the direction from the outside to the inside of the first air inlet 13, the air guide 131 is configured to guide the air at the first air inlet 13 away from the direction of the control unit 12.

[0049] During the operation of the outdoor unit 1 of the air conditioner, the airflow enters the electrical control box 11 from the first air inlet 13, then blows over the electrical control component 12 and flows out of the electrical control box 11 from the air outlet 14. During the process of the airflow blowing over the electrical control component 12, it will exchange heat with the electrical control component 12. During the process of the airflow flowing in the receiving cavity 111, it will exchange heat with the electrical control box 11 and other components in the receiving cavity 111. Thus, the heat dissipation of the electrical control component 10 is achieved.

[0050] During rainy or snowy weather, the airflow entering the outdoor unit 1 housing 20 of the air conditioner inevitably carries rainwater. Part of the airflow entering the electrical control box 11 from the first air inlet 13 also carries rainwater. As those skilled in the art will understand, the electrical control component 10, the control element 12, and the connection between the control element 12 and the control board 15 require high levels of waterproofing.

[0051] In this embodiment, the first air inlet 13 and the electrical control 12 are arranged at a distance in the first direction, and there is a buffer distance between the first air inlet 13 and the electrical control 12. When the airflow enters the electrical control box 11 from the first air inlet 13 and flows toward the electrical control 12, some of the rainwater carried in the airflow will fall into the receiving cavity 111 under the action of gravity. In this way, the water content in the airflow blowing past the electrical control 12 can be reduced.

[0052] Meanwhile, a guide 131 is provided at the first air inlet 13. The guide 131 directs the air at the first air inlet 13 away from the direction of the control unit 12. In this way, the airflow entering from the first air inlet 13 needs to be guided by the inner wall of the receiving cavity 111 and change direction before blowing over the control unit 12. On the one hand, this can increase the flow distance of the airflow before it blows over the control unit 12 in the receiving cavity 111, increase the dripping time of the rainwater carried in the airflow, and thus reduce the water content in the airflow that blows over the control unit 12. On the other hand, it can be understood that when the airflow comes into contact with the inner wall of the receiving cavity 111 and changes the flow direction, the rainwater carried in the airflow will be more likely to remain on the inner wall of the receiving cavity 111. Therefore, when the airflow blows over the control unit 12, the water content in the airflow can be further reduced.

[0053] According to the first aspect embodiment of the present invention, the first air inlet 13 and the control unit 12 are arranged at a distance in a first direction, and the air guide 131 guides the air at the position of the first air inlet 13 away from the direction of the control unit 12, which can reduce the moisture content in the airflow blowing through the control unit 12, thereby improving the waterproof performance of the electronic control component 10 and thus improving the reliability of the electronic control component 10 during operation.

[0054] In some embodiments of this utility model, such as Figure 6 , Figure 7 , Figure 8 , Figure 11 , Figure 12 and Figure 13 As shown, the air guide 131 is a plate extending along the second direction. In the direction from the outside to the inside of the first air inlet 13, the air guide 131 extends obliquely away from the electrical control 12. The second direction is perpendicular to the first direction.

[0055] During the operation of the outdoor unit 1 of the air conditioner, the airflow blown in from the outside of the first air inlet 13 flows along the surface of the air guide 131 as it passes through it. Thus, the air guide 131 directs the air at the first air inlet 13 away from the direction of the electrical control 12. Furthermore, the air guide 131 has a relatively simple structure, making it less difficult to design and manufacture. During product design, parameters such as the size of the air guide 131, its position in the first air inlet 13, or the air guide angle can be adjusted to meet more product design needs.

[0056] In some embodiments of this utility model, such as Figure 8 and Figure 13 As shown, there are multiple air guides 131. For example, there can be two, three, four or ten air guides 131 arranged sequentially in the first direction.

[0057] Therefore, multiple air guides 131 guide the airflow of the first air inlet 13 at multiple positions, which can make the airflow distribution of the first air inlet 13 more uniform, thereby making the cooling airflow in the accommodating cavity 111 more uniform, thus improving the cooling uniformity of the electronic control component 10. In addition, when each air guide 131 comes into contact with the airflow, it can block some of the rainwater carried in the airflow, thereby further reducing the moisture content in the airflow blowing through the electronic control component 12 and improving the reliability of the electronic control component 10 during operation.

[0058] During the product design process, the number of air guides 131 or the distribution of air guides 131 at the first air inlet 13 can be adjusted to meet more product design needs.

[0059] In some embodiments of this utility model, such as Figures 6-10 As shown, the electronic control assembly 10 also includes a heat sink 16 and an electronic control board 15. Both the heat sink 16 and the electronic control unit 12 are connected to the electronic control board 15. Both the heat sink 16 and the electronic control board 15 are located within the receiving cavity 111, with the heat sink 16 positioned between the electronic control unit 12 and the air outlet 14. During operation of the electronic control assembly 10, heat from the electronic control board 15 and the electronic control unit 12 can be transferred to the heat sink 16. It is understood that the heat sink 16 has a high heat exchange efficiency. When airflow passes over the heat sink 16, the heat sink 16 can exchange heat with the airflow more efficiently, thereby further improving the heat dissipation efficiency of the electronic control assembly 10.

[0060] In some embodiments of this utility model, such as Figure 7 and Figure 9As shown, the control box 11 also has a second air inlet 17 that communicates with the receiving cavity 111. The first air inlet 13 and the second air inlet 17 are located on the same side of the control board 15 in the third direction, and the second air inlet 17 is opposite to the heat sink 16 in the third direction. The third direction is the thickness direction of the control board 15, and the first direction is perpendicular to the third direction.

[0061] During the operation of the outdoor unit 1 of the air conditioner, the airflow entering the control box 11 from the first air inlet 13 is guided by the air guide 131 and flows towards the control component 12 under the action of the inner wall of the receiving cavity 111. The airflow blows over the control component 12 and flows towards the radiator 16. At the same time, the airflow entering the control box 11 from the second air inlet 17 blows directly towards the radiator 16. Subsequently, the airflow blown in from the first air inlet 13 and the airflow blown in from the second air inlet 17 flow towards the air outlet 14 after passing through the radiator 16 and flows out from the air outlet 14. Thus, the heat dissipation efficiency of the radiator 16 can be further improved, thereby further improving the heat dissipation efficiency of the control component 10.

[0062] The heat sink 16 is located between the electronic control component 12 and the air outlet 14. The airflow blown into the second air inlet 17, which is opposite to the heat sink 16, is less likely to blow towards the electronic control component 12 after passing through the heat sink 16. In addition, the heat sink 16 will also filter out some of the rainwater carried in the airflow. Therefore, the second air inlet 17 has a low impact on the waterproof performance of the electronic control component 10, which can improve the waterproof performance of the electronic control component 10.

[0063] In some embodiments of this utility model, such as Figure 8 , Figure 9 , Figure 11 and Figure 13 As shown, the receiving cavity 111 includes a heat dissipation duct 112, which includes a first section 113 and a second section 114. The first section 113 is along a first direction (e.g., Figure 11 Extending in the left-right direction shown in the diagram, one end of the first segment 113 is connected to the first air inlet 13, one end of the second segment 114 is connected to the other end of the first segment 113, and the other end of the second segment 114 extends along the second direction (e.g., in the left-right direction). Figure 11 The second direction extends in the vertical direction shown in the figure and connects to the air outlet 14. The second direction is perpendicular to the first direction. The electrical control 12 is located in the first section 113 and the heat sink 16 is located in the second section 114.

[0064] During the operation of the outdoor unit 1 of the air conditioner, the airflow entering through the first air inlet 13 passes through the first section 113 and blows over the electrical control 12, then changes direction and enters the second section 114 and blows over the radiator 16, and then flows out from the air outlet 14. The airflow entering through the second air inlet 17 blows over the radiator 16 and enters the second section 114, and then flows out from the air outlet 14.

[0065] In this design, the heat dissipation duct 112 is configured as a first segment 113 and a second segment 114 that are perpendicular to each other. The electronic control component 12 and the heat sink 16 are respectively located in the first segment 113 and the second segment 114. The size of the electronic control component 10 in the first direction and the second direction will not be too large. In this way, the structure of the electronic control component 10 is relatively compact, which can reduce the difficulty of product design and assembly during the product design and assembly process.

[0066] In some embodiments of this utility model, the heat sink 16 is located at the end of the second segment 114 that is away from the first segment 113 in the second direction. Therefore, the distance between the heat sink 16 and the control component 12 is relatively large, and the distance between the second air inlet 17 opposite to the heat sink 16 and the control component 12 is also relatively large. This further reduces the probability that the airflow blown in through the second air inlet 17 will flow towards the control component 12, thereby further improving the waterproof performance of the control component 10 and increasing the reliability of the control component 10 during operation.

[0067] In some embodiments of this utility model, the air outlet 14 is formed on one side of the other end of the second segment 114 in the first direction, and the distance between the electronic control board 15 and the inner wall of the second segment 114 on the side away from the first segment 113 in the second direction is 5mm-20mm. For example, the distance between the electronic control board 15 and the inner wall of the second segment 114 on the side away from the first segment 113 in the second direction can be 5mm, 6mm, 7mm, 9mm, 14mm, 16mm, 19mm or 20mm.

[0068] In this way, there will be a buffer space between the electronic control board 15 and the inner wall of the second section 114 on the side away from the first section 113 in the second direction. It can be understood that when the airflow entering from the second air inlet 17 flows out towards the air outlet 14, part of the airflow changes its flow direction under the action of negative pressure and flows out of the air outlet 14. The other part of the airflow changes its direction after colliding with the inner wall of the second section 114 on the side away from the first section 113 in the second direction. By setting the buffer space, the airflow that changes its flow direction after the collision can be buffered in the buffer space, thereby reducing the airflow that moves in the opposite direction towards the radiator 16, so that the airflow entering from the second air inlet 17 can flow out more smoothly and improve the heat dissipation efficiency of the electronic control component 10.

[0069] In some embodiments of this utility model, such as Figure 7 , Figure 11 and Figure 14 As shown, the electrical control box 11 also has an open opening 18 that communicates with the first section 113. The open opening 18 and the first air inlet 13 are in a third direction (e.g., Figure 11The front and rear directions shown are opposite each other, and the first, second, and third directions are perpendicular to each other. After the electronic control assembly 10 is assembled into the housing 20, the opening 18 can be aligned with the inner wall of the housing 20. In this way, the inner wall of the housing 20 can cooperate with the inner wall of the receiving cavity 111 to restrict the flow path of airflow, thereby saving materials for the production of the electronic control box 11 and reducing production costs. During the operation of the outdoor unit 1 of the air conditioner, when the airflow rate in the electronic control box 11 is large and the air pressure in the electronic control box 11 is high, some airflow can flow out from the gap between the edge of the opening 18 and the inner wall of the housing 20, so that the airflow can enter and exit the electronic control box 11 normally.

[0070] In some embodiments of this utility model, such as Figure 10 As shown, the electrical control component 12 includes an inductor 121 and a capacitor 122, both of which are connected to the control board 15. The inductor 121 and capacitor 122 are spaced apart from the opening 18 in the first direction. It is understood that during the operation of the outdoor unit 1, airflow will blow towards the electrical control component 10 from inside the housing 20. When the airflow inside the housing 20 is large, some airflow will enter the opening 18 through the gap between the inner wall of the housing 20 and the side of the control box 11 with the opening 18. Because the inductor 121 and capacitor 122 are spaced apart in the first direction, when the airflow enters the control box 11 from the opening 18, the airflow will not directly blow towards the electrical control component 12. Thus, even if the airflow carries rainwater, the water content of the airflow entering from the opening 18 is low when it passes over the inductor 121 and capacitor 122. This improves the waterproof performance of the electrical control component 10, thereby increasing its reliability during operation.

[0071] In some embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 14 As shown, the second direction is the vertical direction, and the lower end of the opening 18 is also provided with a first flange 181 extending vertically. The electronic control component 10 is located at the top inside the housing 20. Inside the housing 20, airflow can easily enter the opening 18 from the gap between the lower end of the electronic control box 11 and the inner wall of the housing 20. By providing the first flange 181 extending vertically along the lower end of the opening 18, the first flange 181 can prevent a portion of the airflow from flowing into the opening 18 from the gap between the lower end of the electronic control box 11 and the inner wall of the housing 20, thereby further improving the waterproof performance of the electronic control component 10 and further improving the reliability of the electronic control component 10 during operation.

[0072] In some embodiments of this utility model, the electrical control box 11 also has a third air inlet on one side wall in the first direction, which communicates with the receiving cavity 111. In the first direction, the first air inlet 13 is located between the electrical control box 12 and the third air inlet.

[0073] Therefore, during the operation of the outdoor unit 1 of the air conditioner, the airflow can also enter the electrical control box 11 from the third air inlet, which can increase the heat dissipation air volume in the electrical control box 11, thereby further improving the heat dissipation efficiency of the electrical control component 10.

[0074] Furthermore, the first air inlet 13 is located between the electronic control unit 12 and the third air inlet. The distance between the third air inlet and the electronic control unit 12 is relatively large. As the airflow flowing into the third air inlet travels towards the electronic control unit 12, the rainwater droplets carried in the airflow travel a longer distance, which can reduce the moisture content of the airflow when it reaches the electronic control unit 12. At the same time, the air guide 131 guides the airflow blown in by the first air inlet 13 to the third air inlet. The interaction between the two airflows allows the airflow to better contact the inner wall of the receiving cavity 111, thereby leaving more rainwater carried in the airflow on the inner wall of the receiving cavity 111. This can further reduce the moisture content of the airflow when it reaches the electronic control unit 12 and improve the reliability of the electronic control component 10 during operation.

[0075] Preferably, the third air inlet is provided with louvers, which can make the airflow entering the third air inlet more uniform and can adjust the airflow direction of the third air inlet.

[0076] The following is for reference. Figures 1-14 The outdoor unit 1 of an air conditioner according to a second aspect embodiment of the present invention is described.

[0077] According to the second aspect embodiment of the present utility model, the outdoor unit 1 of the air conditioner is as follows: Figures 1-5 As shown, it includes: housing 20 and the electronic control component 10 according to the first aspect of the present invention.

[0078] Specifically, the housing 20 is provided with a partition 24, which separates the impeller compartment 21 and the compressor compartment 22 within the housing 20. The partition 24 is provided with a connecting port connecting the impeller compartment 21 and the compressor compartment 22. The electrical control component 10 is located in the compressor compartment 22, and the air outlet 14 is connected to the impeller compartment 21 through the connecting port.

[0079] The wind turbine compartment 21 contains a wind turbine 23, the compressor compartment 22 contains a compressor and other components, and the housing 20 includes a housing body 26, a first panel 27, a second panel 28 and a top cover 29. The front and top sides of the housing body 26 are open, the top cover 29 covers the top side of the housing body 26, the first panel 27 covers the front side of the housing body 26 and seals the wind turbine compartment 21, and the second panel 28 covers the front side of the housing body 26 and seals the compressor compartment 22. During the operation of the outdoor unit 1 of the air conditioner, the fan wheel 23 rotates and generates negative pressure in the fan wheel chamber 21. Airflow enters the fan wheel chamber 21 from the rear side and blows it out of the fan wheel chamber 21. At the same time, the airflow in the compressor chamber 22 enters the electrical control box 11. The airflow blows out the electrical control component 12 and the radiator 16 in sequence in the receiving cavity 111, and then enters the fan wheel chamber 21 through the middle partition 24 from the air outlet 14. In the fan wheel chamber 21, it blows out of the fan wheel chamber 21 together with the airflow in the front and rear directions. In this way, heat dissipation of the electrical control component 10 can be achieved.

[0080] When the airflow in the compressor compartment 22 enters the electrical control box 11 and blows through the electrical control component 12, the water content in the airflow is low, the waterproof performance of the electrical control component 10 is good, and the probability of short circuit of the electrical control component 10 during the operation of the outdoor unit 1 of the air conditioner is low, which can improve the reliability of the outdoor unit 1 of the air conditioner during operation.

[0081] According to the second aspect embodiment of the present invention, the reliability of the air conditioner outdoor unit 1 can be improved by setting the electronic control component 10 according to the first aspect embodiment of the present invention.

[0082] In some embodiments of this utility model, such as Figures 3-5 As shown, the electronic control component 10 is located at the front of the compressor compartment 22, and the first air inlet 13 is formed at the rear of the electronic control box 11.

[0083] During the operation of the outdoor unit 1 of the air conditioner, the impeller 23 generates negative pressure that causes the airflow to flow forward. In this way, the negative pressure in the impeller compartment 21 is transferred to the compressor compartment 22. Under the action of negative pressure, the airflow in the compressor compartment 22 can flow from back to front and enter the electrical control box 11 from the first air inlet 13. As a result, the airflow in the compressor compartment 22 enters the electrical control box 11 located at the front of the compressor compartment 22 more smoothly. Moreover, the airflow travels a longer distance in the compressor compartment 22 before entering the electrical control box 11, which allows sufficient time for rainwater in the airflow to fall, thereby reducing the moisture content of the airflow entering the electrical control box 11.

[0084] In some embodiments of this utility model, the distance between the upper end of the electrical control box 11 and the top wall of the compressor compartment 22 is less than or equal to 10mm. For example, the distance between the upper end of the electrical control box 11 and the top wall of the compressor compartment 22 can be 1mm, 2mm, 5mm, 6.5mm, 7.7mm, 8.4mm, 9mm or 10mm. As a result, during the operation of the outdoor unit 1, the airflow from the gap between the upper end of the electrical control box 11 and the top wall of the compressor compartment 22 to the front of the electrical control box 11 is less, and the airflow from the open opening 18 at the front of the electrical control box 11 into the receiving cavity 111 is also less. This allows the waterproof performance of the electrical control component 10 to meet the requirements. Furthermore, vibrations are inevitable during the operation of the outdoor unit 1. The aforementioned distance can provide deformation space on the upper side of the electrical control box 11, reducing the probability of the upper end of the electrical control box 11 striking the top wall of the compressor during the operation of the outdoor unit 1, and improving the quietness of the outdoor unit 1 during operation. During the product design process, the distance between the upper end of the electrical control box 11 and the top wall of the compressor compartment 22 can be adjusted to meet more product design needs.

[0085] In some embodiments of this utility model, the front side of the electrical control box 11 is further formed with an open opening 18 communicating with the receiving cavity 111. The distance between the lower edge of the open opening 18 and the front inner wall of the compressor compartment 22 is 2mm-10mm. For example, the distance between the lower edge of the open opening 18 and the front inner wall of the compressor compartment 22 can be 2mm, 3mm, 7mm, 8mm, 9mm, or 10mm. In this way, the airflow into the open opening 18 between the lower edge of the open opening 18 and the front inner wall of the compressor compartment 22 is relatively small, which can ensure that the waterproof performance of the electrical control component 10 meets the requirements. During the product design process, the distance between the lower edge of the open opening 18 and the front inner wall of the compressor compartment 22 can be adjusted to meet more product design needs.

[0086] In some embodiments of this utility model, the distance between the front edge of the upper end of the electrical control box 11 and the front inner wall of the compressor compartment 22 is 3mm-8mm. For example, the distance between the front edge of the upper end of the electrical control box 11 and the front inner wall of the compressor compartment 22 can be 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm. In this way, the airflow into the opening 18 from between the front edge of the upper end of the electrical control box 11 and the front inner wall of the compressor compartment 22 is relatively small, which can ensure that the waterproof performance of the electrical control component 10 meets the requirements. During the product design process, the distance between the front edge of the upper end of the electrical control box 11 and the front inner wall of the compressor compartment 22 can be adjusted to meet more product design needs.

[0087] In some embodiments of this utility model, the front edge of the upper end of the electrical control box 11 is provided with an upwardly folded second flange. By providing the second flange, a portion of the airflow can be prevented from entering the front side of the electrical control box 11 from the gap between the upper end of the electrical control box 11 and the top wall of the compressor compartment 22, and then entering the electrical control box 11 from the opening 18, thereby further improving the waterproof performance of the electrical control component 10.

[0088] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the housing 20 also has an air inlet 25 that communicates with the compressor compartment 22. The air inlet 25 is located at the rear end of the side wall of the compressor compartment 22 away from the impeller compartment 21, and / or the air inlet 25 is located on the rear side wall of the compressor compartment 22.

[0089] In other words, the air inlet 25 can be located at the rear end of the side wall of the compressor compartment 22 away from the wind turbine compartment 21, or the air inlet 25 can be located on the rear side wall of the compressor compartment 22, or the air inlet 25 can be located at the rear end of the side wall of the compressor compartment 22 away from the wind turbine compartment 21 and on the rear side wall of the compressor compartment 22.

[0090] During the operation of the outdoor unit 1 of the air conditioner, the airflow enters the compressor compartment 22 through the air inlet 25, then flows through the electrical control box 11 and passes through the partition 24 into the impeller compartment 21, and then blows forward in the impeller compartment 21. The distance between the air inlet 25 and the electrical control box 11 in the front-to-back direction is relatively large. During the flow of the airflow in the compressor compartment 22, the rainwater in the airflow has a longer time to fall, which can improve the waterproof performance of the electrical control components 10.
