[0002] Existing air conditioner outdoor units typically consist of a fan chamber and a compressor chamber, with the electrical control box located in the compressor chamber to control the operation of the outdoor unit. However, because the outdoor unit is exposed to the outdoor environment for extended periods, rainwater, snowmelt, and other liquids can easily enter the compressor chamber through heat dissipation channels or gaps, causing the electronic components in the electrical control box to become damp or damaged, thus affecting the reliability and lifespan of the outdoor unit.

[0003] However, there is at least one problem with the relevant technology: In the existing technology, most outdoor units prevent water droplets from entering by setting up simple water-blocking structures, but these structures often cannot simultaneously achieve heat dissipation efficiency and waterproof performance.

[0015] In one embodiment of this utility model, the windproof upright plate includes: a third side wall, which is located at the position of the windproof upright plate corresponding to the water tank; wherein, the projection of the water baffle onto the windproof upright plate covers the water passage hole.

[0020] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting a limiting component at the lower end of the water baffle and cooperating with the limiting port on the windproof plate, the water baffle and the windproof plate can achieve a stable locking connection, which improves the assembly accuracy and stability of the structure, reduces the risk of the water baffle loosening due to vibration or external impact, and thus ensures the long-term reliability of the heat dissipation channel and the waterproof structure.

[0021] In one embodiment of this utility model, the outdoor unit further includes: a right side plate, which is located on the side of the electrical control box away from the windproof upright plate, and a third air outlet is provided on the right side plate to connect to the installation chamber.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] See Figures 1 to 5 This utility model provides an outdoor unit 1, which includes a windproof panel 30 and an electrical control box. The windproof panel 30 divides the outdoor unit 1 into a fan chamber 10 and a compressor chamber 20. The windproof panel 30 has a first air outlet 31. The electrical control box is located in the compressor chamber 20. A water baffle 40 is provided on the side of the electrical control box near the windproof panel 30. A second air outlet 41 is provided on the water baffle 40. The second air outlet 41 is used to communicate with the installation chamber 51 where the electronic components of the electrical control box are located. A heat dissipation channel connecting the first air outlet 31 and the second air outlet 41 is formed between the water baffle 40 and the windproof panel 30. The projection of the water baffle 40 onto the windproof panel 30 covers the first air outlet 31. A guide 42 is provided on the side of the water baffle 40 near the windproof panel 30 to limit water droplets from entering the electrical control box.

[0031] By setting a first air outlet 31 in the area corresponding to the electrical control box, and setting a second air outlet 41 on the water baffle 40 to form a heat dissipation channel with the windproof plate 30, it is ensured that the electronic components of the electrical control box can be effectively dissipated through the heat dissipation channel; at the same time, the projection of the water baffle 40 covers the first air outlet 31, which can effectively block water droplets entering from the first air outlet 31 from entering the compressor chamber 20; in addition, by limiting water droplets from entering the compressor chamber 20 through the guide 42, the waterproof performance of the outdoor unit 1 and the reliability of the electronic components can be further improved.

[0032] Preferably, the electrical control box includes a base 50 and a water baffle 40, which are integrally formed. The base 50 is disposed between the windproof upright plate 30 and the right side plate 60 of the outdoor unit 1. In this utility model, the four corners of the base 50 are respectively connected to the windproof upright plate 30 and the right side plate 60. Through multiple fixation, the stability of the water baffle 40 and the base 50 when installed on the outdoor unit 1 is increased.

[0033] Preferably, in this utility model, the installation chamber 51 is located on the side of the water baffle 40 away from the windproof upright plate 30, and the installation chamber 51 is surrounded by the water baffle 40 and the base 50. The electronic components of the electrical control box are installed on the base 50 to facilitate heat dissipation.

[0034] For example, in this utility model, when water droplets in the fan chamber 10 enter the first air outlet 31 from the fan chamber 10, the path of the water droplets is blocked by the inner wall of the water baffle 40, and thus they cannot enter the installation chamber 51 through the second air outlet 41.

[0035] Preferably, the first air outlet 31 is located on the upper left side of the air-insulating plate 30, and the electrical control box is located on the upper side of the compressor chamber 20 corresponding to the first air outlet 31, so as to shorten the flow path of the air duct and thus dissipate heat from the electronic components inside the electrical control box.

[0036] Preferably, in this utility model, multiple first air outlets 31 are provided. When calculating the distance from the first air outlet 31 to the second air outlet 41, the first air outlet 31 that is closest to the second air outlet 41 is used for calculation.

[0037] Furthermore, the water shield 40 includes a first sidewall 43. The first sidewall 43 is located above the second air outlet 41; one end of the guide member 42 is connected to the first sidewall 43, and the other end extends toward the direction close to the windproof upright plate 30 to guide water droplets away from the electrical control box.

[0038] The design of the first sidewall 43 of the water shield 40 and the guide 42 guides water droplets away from the electrical control box, further enhancing the waterproof effect and preventing water droplets from entering the electrical control box through the second air outlet 41, thus protecting electronic components from moisture damage.

[0039] For example, in this invention, the guide member 42 consists of multiple ribs arranged on the inner wall of the water baffle 40. When the upper side wall of the water baffle 40 blocks water droplets from the first air outlet 31, the ribs block water flowing downward along the first side wall 43. When the water droplets fall from the edge of the ribs, they move away from the second air outlet 41 in the horizontal direction, making it more difficult for them to enter the installation chamber 51 through the second air outlet 41.

[0040] Specifically, without the guide element 42, when water droplets fall down along the first side wall 43, due to vibration or airflow disturbance, the water droplets may fall onto the lower edge of the second air outlet 41 and then collapse into the installation chamber 51. Compared with the case without the guide element 42, this utility model further increases the water-blocking performance of the waterproof cover.

[0041] Preferably, the guide element 42 in this utility model is not limited in shape. As long as it can satisfy the requirement that water droplets can fall and that the lower edge of the guide element 42 and the lower edge of the second air outlet 41 have a positional difference in horizontal projection, it can be considered as the guide element 42 in this utility model.

[0042] Preferably, the present invention can also tilt the first sidewall 43 while minimizing the impact on heat dissipation performance, or directly offset the first sidewall 43 and the water baffle 40 below the second air outlet 41, so that when water droplets fall from the lower end of the first sidewall 43, they will have a horizontal position difference with the second air outlet 41, so that it can produce the same effect as the guide 42.

[0043] Specifically, in this embodiment of the utility model, the guide 42 is a raised rib, and multiple ribs are provided. When calculating the position difference between the lower edge of the guide 42 and the second air outlet 41, the raised rib with the largest distance from the second air outlet 41 in the horizontal direction is used by default for calculation.

[0044] Furthermore, the water baffle 40 also includes a second side wall 44 and a base plate 45. The second side wall 44 is located below the second air outlet 41; the base plate 45 is located on the lower side of the water baffle 40 and is connected to the second side wall 44; wherein, the base plate 45, the second side wall 44, and the windproof upright plate 30 cooperate to form a water-receiving trough 46, and the windproof upright plate 30 is provided with a water passage hole 33 communicating with the water-receiving trough 46.

[0045] The second side wall 44 and bottom plate 45 of the water shield 40 cooperate with the windproof upright plate 30 to form a water tank 46 to collect any water droplets that may enter; the accumulated water is discharged through the water passage hole 33 on the windproof upright plate 30 to prevent water droplets from accumulating near the electrical control box, thereby further improving the waterproofness and operational reliability of the electrical control box.

[0046] Preferably, in order to ensure that the water in the water tank 46 can flow smoothly into the fan chamber 10, the bottom plate 45 should be a flat plate with a certain inclination, or a bottom plate 45 of other shapes that allows the water to flow naturally towards the fan chamber 10.

[0047] Preferably, the water tank 46 in this utility model can also be separately arranged between the windproof upright plate 30 and the water baffle 40, and is a water-receiving component located below the second air outlet 41, such as a water receiving tray.

[0048] Furthermore, the projection of the base plate 45 onto the windproof upright plate 30 falls within the area enclosed by the water passage hole 33. This ensures that the water in the water tank 46 can be completely discharged through the water passage hole 33, preventing water overflow or stagnation and improving drainage efficiency and waterproofing effect.

[0049] Furthermore, the base plate 45 has an inclined slope extending toward the windproof upright plate 30 to guide water flow toward the water passage hole 33. The inclined slope design of the base plate 45 guides water flow toward the water passage hole 33, accelerates the drainage process, reduces the residence time of water in the water tank 46, and further optimizes waterproof performance and drainage efficiency.

[0050] Preferably, according to Figure 3 The direction indicator in the middle, the base plate 45 can be tilted in the front-back direction, or in the left-right direction, or a combination of both.

[0051] Furthermore, the windproof upright plate 30 includes a third side wall 32. The third side wall 32 is located at the position of the windproof upright plate 30 corresponding to the water tank 46; wherein, the projection of the water baffle 40 onto the windproof upright plate 30 covers the water passage hole 33.

[0052] The third side wall 32 of the windproof upright plate 30 is provided with water passage holes 33 to increase the ventilation capacity of the heat dissipation channel and improve the heat dissipation efficiency of the electrical control box; the water shield 40 covers the water passage holes 33 to prevent water droplets from entering the electrical control box through the water passage holes 33, thus taking into account both heat dissipation and waterproofing.

[0053] Preferably, in this embodiment of the present invention, multiple water passage holes 33 are provided; further, in order to ensure the drainage effect of the water tank 46, at least one of the multiple water passage holes 33 should be connected to the bottom plate 45 so that the water in the water tank 46 can be drained.

[0054] Furthermore, the windproof upright plate 30 also includes a louver structure 34, which is respectively located at the first air outlet 31 and the water passage hole 33.

[0055] By setting louvered structures 34 at the first air outlet 31 and water passage 33, the airflow direction can be guided, the air circulation efficiency of the heat dissipation channel can be optimized, and external foreign objects can be prevented from entering the compressor chamber 20 or fan chamber 10 through the air outlet, thereby improving the operational stability and durability of the outdoor unit 1.

[0056] Preferably, the louver structure 34 has a downwardly curved arc structure. On the one hand, when the airflow passes through the louver structure 34, it can guide the airflow downward to the fan blades, increasing the efficiency of heat dissipation. On the other hand, water droplets are guided by the louver structure 34 and fall onto the first side wall 43, shortening the movement path of the water droplets. Moreover, when the water droplets fall onto the floor and are discharged from the water passage 33 into the fan chamber 10, they will not be obstructed by the louver structure 34, and can flow smoothly into the fan chamber 10 through the arc structure of the louver structure 34.

[0057] Furthermore, the water shield 40 also includes a limiting member 47, which is located at the lower end of the water shield 40. The windproof upright plate 30 is provided with a limiting opening 35 that cooperates with the limiting member 47, so that the water shield 40 and the windproof upright plate 30 are engaged.

[0058] Preferably, a separate guide plate can also be provided between the water baffle 40 and the windproof upright plate 30. The guide plate is located between the first air outlet 31 and the second air outlet 41 to guide the flow direction of airflow and water droplets, thereby enhancing heat dissipation efficiency and drainage efficiency.

[0059] By setting a limiting member 47 at the lower end of the water baffle 40 and cooperating with the limiting port 35 on the windproof upright plate 30, the water baffle 40 and the windproof upright plate 30 can achieve a stable snap-fit ​​connection, which improves the assembly accuracy and stability of the structure, reduces the risk of the water baffle 40 loosening due to vibration or external impact, and thus ensures the long-term reliability of the heat dissipation channel and waterproof structure.

[0060] Preferably, the limiting port 35 cooperates with the four corners of the base 50 to form multiple fixation, thereby enhancing the stability of the water shield 40 and the base 50 when they are fixed.

[0061] Furthermore, the outdoor unit 1 also includes a right side panel 60. The right side panel 60 is located on the side of the electrical control box away from the windproof upright plate 30, and a third air outlet 61 is provided on the right side panel 60 to connect to the mounting chamber 51. The provision of a third air outlet 61 on the right side panel 60 on the side of the electrical control box away from the windproof upright plate 30 increases the ventilation path of the electrical control box mounting chamber 51, further improves heat dissipation efficiency, and ensures stable operation of electronic components in high-temperature environments.

[0062] Preferably, when the fan blades in the fan chamber 10 are running, a negative pressure is generated in the fan chamber 10, causing airflow to enter from the third air outlet 61, pass through the electronic components in the mounting chamber 51, and flow out from the second air outlet 41, thereby dissipating heat from the electronic components.

[0063] Preferably, the water passage 33 is located below the second air outlet 41. When the airflow flows out of the second air outlet 41 from the installation chamber 51, both the water passage 33 and the second air outlet 41 can serve as air outlets through which the airflow passes, thereby increasing the air duct path that can dissipate heat and thus increasing the heat dissipation efficiency of the outdoor unit 1.

[0064] On the other hand, this utility model also provides an air conditioner, including an outdoor unit 1 as described in any of the above examples. Although this utility model has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model; therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
