Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.
[0024] The embodiment of the present application provides an electric control box to solve the problems of poor waterproofness and heat dissipation of electric control boxes in the related art.
[0025] In the embodiments of this application, Figure 1 and Figure 2 As shown, the electric control box includes a box body 1 and a shielding member 2. The peripheral wall of the box body 1 is provided with a first heat dissipation opening and a first water retaining portion 11. The first water retaining portion 11 is provided on the outside of the box body 1 and shields at least part of the first heat dissipation opening.
[0026] The shielding member 2 is arranged in the box body 1, and is provided with a shielding portion 21. The shielding portion 21 is arranged relative to the first heat dissipation port. The shielding member 2 is also provided with a second heat dissipation port, and the second heat dissipation port is staggered with the first heat dissipation port.
[0027] It should be noted that the peripheral wall of the box body 1 refers to at least a portion of the structure surrounding the box body 1 in all directions. The staggered arrangement of the second heat dissipation opening and the first heat dissipation opening means that the orthographic projection of the side wall of the second heat dissipation opening on the plane where the first heat dissipation opening is located does not overlap with the first heat dissipation opening.
[0028] It is understood that the first water retaining portion 11 blocking at least a portion of the first heat dissipation port can prevent most condensation from entering the box body 1 through the first heat dissipation port, and the blocking position of the first water retaining portion 11 can be set according to the source of the condensation water, so that the electrical control box has better waterproof and heat dissipation effects. In addition, a shielding member 2 is further provided within the box body 1. On the one hand, the shielding member 2 can block some of the condensation water entering through the first heat dissipation port. On the other hand, the second heat dissipation port disposed staggered with the first heat dissipation port can accelerate the heat dissipation speed of the box body 1 while ensuring the blocking effect of the shielding member 2, thereby improving the waterproof and heat dissipation effects of the electrical control box.
[0029] In some embodiments, as Figure 2As shown, the shielding portion 21 is provided with a drainage groove 23 facing the first heat dissipation opening. The drainage groove 23 extends vertically to allow condensed water to drain downward. It is understood that some condensed water entering through the first heat dissipation opening is diverted by the shielding member 2 and then drained along the drainage groove 23, making it less likely for the condensed water to remain in the box body 1, thereby improving the waterproof effect.
[0030] In some embodiments, as Figure 2 As shown, the shielding member 2 further includes a water guide portion 22 , which is connected to the lower end of the shielding portion 21 and extends in a direction away from the box body 1 .
[0031] It should be noted that the shielding portion 21 is a structure for changing the flow direction of condensation water entering through the first heat dissipation port, and the water diversion portion 22 and at least a portion of the shielding portion 21 enclose a drainage groove 23, which means that a portion of the drainage groove 23 is formed on the shielding portion 21, and the other portion is formed on the water diversion portion 22. The lower end of the water diversion portion 22 extends downward and toward the outside of the box body 1.
[0032] It is understandable that the condensed water is directed away from the box body 1 by the water guide portion 22 to prevent external factors, such as strong wind, from blowing the condensed water into the box body 1.
[0033] In some embodiments, as Figure 3 As shown, the orthographic projection of the first heat dissipation opening on the shielding member 2 is located in the drainage groove 23. It is understandable that since condensation water has a tendency to diffuse when splashing, by making the drainage groove 23 have a larger area than the first heat dissipation opening, more condensation water can be collected and discharged.
[0034] In some embodiments, as Figure 2 As shown, the shielding member 2 is provided with a second water blocking portion 24 , which is provided on a side of the shielding member 2 facing the first heat dissipation opening and blocks at least a portion of the second heat dissipation opening.
[0035] It should be noted that the shielding position of the second water retaining portion 24 can be set according to the main splashing direction of the condensation water at the first heat dissipation outlet, so that the second heat dissipation outlet extends along a position opposite to the source of the condensation water, so that the shielding member 2 has a better waterproof effect without affecting the heat dissipation effect of the second heat dissipation outlet.
[0036] In some embodiments, as Figure 2As shown, multiple first and second heat dissipation vents are spaced apart from each other. Because the first and second heat dissipation vents are spaced apart from each other, the multiple first and second heat dissipation vents can be arranged in a manner such that: multiple first heat dissipation columns are spaced apart horizontally, each first heat dissipation column includes multiple first heat dissipation vents spaced apart vertically; multiple second heat dissipation columns are spaced apart horizontally, each second heat dissipation column includes multiple second heat dissipation vents spaced apart vertically; and the first and second heat dissipation columns are staggered. The multiple first and second heat dissipation vents further enhance waterproofing and heat dissipation.
[0037] In some embodiments, as Figure 3 As shown, the distance between the second heat dissipation port and the side wall of the box body 1 where the first heat dissipation port is located is less than the distance between the bottom of the drainage groove 23 and the side wall of the box body 1 where the first heat dissipation port is located. It can be understood that the second heat dissipation port is closer to the first heat dissipation port than to the bottom of the drainage groove 23. This places the second heat dissipation port closer to a blind spot where condensation water cannot splash, thus improving the second heat dissipation port's waterproofing effectiveness.
[0038] In some embodiments, as Figure 2 As shown, the shielding portion 21 and the water diversion portion 22 are formed by bending a flat plate, and the shielding portion 21 is further bent to form a plane where the second heat dissipation port is located and a portion of the drainage groove 23 is located in the shielding portion 21. It can be understood that the side of the second heat dissipation port facing away from the first heat dissipation port is recessed in the plane where the bottom of the drainage groove 23 is located, which makes the second heat dissipation port closer to the blind spot where condensation water cannot splash, and provides more space for the placement of the electronic components 3 and between the shielding member 2 and the side wall of the box body 1.
[0039] In some embodiments, as Figure 3 As shown, the box body 1 is provided with a third heat dissipation port and a third water retaining portion 12. The third water retaining portion 12 is provided on the outside of the box body 1 and blocks at least a portion of the third heat dissipation port. The third heat dissipation port and the first heat dissipation port are respectively located on opposite sides of the box body 1. It can be understood that the heat dissipation effect of the box body 1 is further improved by the third heat dissipation port. The purpose of the third heat dissipation port and the first heat dissipation port being respectively located on opposite sides of the box body 1 is to form a flow field in which air enters one side of the box body 1 and exits the other side, thereby accelerating the flow rate of hot air within the box body 1 and improving the heat dissipation effect.
[0040] In some embodiments, as Figure 2 and Figure 3As shown, the electrical control box also includes electronic components 3, which are disposed within the box body 1 and located between the shielding member 2 and the third heat dissipation port. It is understood that placing the electronic components 3 between the shielding member 2 and the third heat dissipation port allows the shielding member 2 to better protect the electronic components 3 from water. Furthermore, a second water retaining portion 24 is provided around the second heat dissipation port of the shielding member 2, located between the shielding member 2 and the first heat dissipation port.
[0041] In some embodiments, as Figure 3 As shown, a plurality of third heat dissipation openings are provided at intervals along the vertical direction and the horizontal direction, and the plurality of third heat dissipation openings are arranged opposite to the plurality of second heat dissipation openings. It should be noted that the plurality of third heat dissipation openings refers to the plurality of third water retaining portions 12 and third heat dissipation openings surrounding the third heat dissipation openings.
[0042] In some embodiments, as Figure 2 As shown, the electric control box further includes a base 4 , which is located at the lower side of the shielding member 2 to support the shielding member 2 .
[0043] The present application also provides an air conditioner outdoor unit comprising a main body, fan blades, and the aforementioned electronic control box. The specific structure of the first subject matter is similar to that of the aforementioned embodiments. Since the present air conditioner outdoor unit utilizes all the technical solutions of all the aforementioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. The fan blades are rotatably connected to the main body, and the electronic control box is located within the main body.
