Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner outdoor unit products, and particularly relates to an electric control box and an air conditioner outdoor unit. Background Art

[0002] When the air conditioner outdoor unit is operating, a large amount of heat of the condenser is dissipated, which poses a threat to electronic components such as the main control board in the electric control box of the air conditioner outdoor unit. When the temperature is high, it is easy to shorten the service life of the electronic components or even directly damage them, resulting in the abnormal operation of the air conditioner. Therefore, when the outer motor of the air conditioner outdoor unit is running, the outdoor wind passes through the condenser upwards and blows out from the mesh cover, forming an upward air field. The electric control box is designed with an air inlet and an air outlet, and air-cooled heat dissipation is achieved by means of the above air field.

[0003] However, currently, the air outlet of the electric control box is arranged on the back of the electric control board in the electric control box, that is, the air outlet is on the side of the box body of the electric control box. Usually, a relatively large ventilation opening needs to be opened on the side of the electric control box to ensure sufficient air volume passes through. This design method will directly cause the size of the electric control box to increase in the horizontal direction, resulting in a large space occupied by the electric control box. In addition, in order to cooperate with the air outlet method on the side of the electric control box, the internal structure design of the electric control box may need to be adjusted accordingly, such as setting air ducts, installing fans, etc. The optimization of these internal structures and the increase in size will occupy a certain space, and also make the space occupied by the electric control box large. At the same time, the air field is poor when the air blows out from the side of the box body of the electric control box, which affects the air volume and the heat dissipation effect is poor.

[0004] That is to say, the electric control box performs air-cooled heat dissipation in the way of air inlet from the bottom of the box body and air outlet from the side of the box body, which occupies a large space, affects the air volume, has a poor air field, and is not conducive to the heat dissipation of the electric control box.

[0030] Please refer to Figure 1 and Figure 2 , this application provides an electric control box 100. The electric control box 100 includes a box body 10 and a wind deflector 20. An air inlet 11 is provided at the bottom of the box body 10, and a first air outlet 12 is provided at the top of the box body 10. The wind deflector 20 is fixedly arranged above the first air outlet 12. The wind deflector 20 and the box body 10 form a second air outlet 13, and the first air outlet 12 is communicated with the second air outlet 13.

[0031] Specifically, this application is provided with two air outlets, namely the first air outlet 12 provided at the top of the box body 10 of the electric control box 100 and the second air outlet 13 formed with the wind deflector 20 above the top of the box body 10 of the electric control box 100.

[0032] That is to say, the side air outlet grille of the electric control box 100 is cancelled in this application, and there is no need to increase the size of the electric control box in the horizontal direction. The layout of the internal components of the electric control box also does not need to be optimized additionally, so that the overall space occupied by the electric control box 100 is reduced, the cost is reduced, and the weight is reduced.

[0033] The air outlet of the electric control box 100 of this application is adjusted to the top of the box body 10 of the electric control box 100, which increases the air outlet area, reduces the overall occupied space of the electric control box 100, and the air duct inside the electric control box 100 flows from bottom to top, with a better air field, an increased air outlet volume, and an improved heat dissipation effect.

[0034] In addition, the air outlet of the electric control box 100 of this application is adjusted to the top of the box body 10 of the electric control box 100, and the overall height of the electric control box 100 can be appropriately reduced, so that the flowing distance of the air duct inside the electric control box 100 from bottom to top is shorter, the air field is improved, and the heat dissipation effect is better.

[0035] In some embodiments, the wind deflector 20 is in a "one" shape. That is to say, the air outlet channel between the first air outlet 12 and the second air outlet 13 is also in a "one" shape, and the air flowing out of the first air outlet 12 will be blocked by the wind deflector 20 above and flow out to the side of the box body 10.

[0036] The wind deflector 20 of this application is arranged in a "one" shape above the first air outlet 12. While forming the second air outlet 13, it can also play a role in blocking water for the first air outlet 12, so as to play a waterproof role.

[0037] Please refer to Figure 2, in some embodiments, the wind deflector 20 includes a first wind deflector portion 21 and a second wind deflector portion 22. The first wind deflector portion 21 is spaced apart from the first air outlet 12, and the second wind deflector portion 22 is spaced apart from the side wall of the box body 10 to form a second air outlet 13.

[0038] That is, the air outlet directions of the two air outlets of the electric control box 100 of the present application are different and are located at different heights of the box body 100, so that the air outlet channel between the first air outlet 12 and the second air outlet 13 is in a labyrinth shape, which is beneficial to waterproof the first air outlet 12 while achieving a heat dissipation effect.

[0039] Specifically, in one embodiment, the wind deflector 20 is in an L shape. At this time, the air outlet channel formed by the first air outlet 12 and the second air outlet 13 is also in an L shape. The air flowing out from the first air outlet 12 will be blocked by the wind deflector 20 above and then bend outwards towards the side of the box body 10 to form a labyrinth-shaped air outlet channel. At this time, the overall air flow direction of the electric control box 100 of the present application is from the air inlet 11 to the first air outlet 12 and then flows out of the second air outlet 13 through the bent L-shaped air outlet channel.

[0040] An L-shaped baffle can be fixed to the top of the box body 10 of the electric control box 100 of the present application, which can not only achieve a heat dissipation effect but also preferably play a role in waterproofing the first air outlet 12.

[0041] In some embodiments, the wind deflector 20 may further include a third wind deflector portion 23 disposed below the second air outlet 13 and fixed to the side of the box body 10. The third wind deflector portion 23 and the second wind deflector portion 22 form the second air outlet 13. The third wind deflector portion 23 can prevent the hot air flowing out from the second air outlet 13 from blowing over the side of the box body 10 of the electric control box 100, thereby avoiding the box body 10 being affected by the hot air again, resulting in poor heat dissipation effect inside the box body 10, and further enabling the electric control box 100 to achieve a good heat dissipation effect.

[0042] In some embodiments, the wind deflector 20 is welded or fixedly connected to the top of the box body 10 by screws.

[0043] Specifically, in one embodiment, only one end of the wind deflector 20 may be fixed to the box body 10. As Figure 2 shown, the first wind deflector portion 21 of the wind deflector 20 may be welded or fixedly connected by screws to the hanging portion 101 of the box body 10. The hanging portion 101 of the box body 10 is used to hang the electric control box 100, so as to realize the welding and fixing of the corresponding part of the wind deflector 20 and the top of the box body 10.

[0044] In another embodiment, both sides of the wind deflector 20 are fixed to the box body 10. The first side end 24 and the second side end 25 of the wind deflector 20 can also be welded to both sides of the top of the box body 10 respectively, so that the wind deflector 20 can block the first air outlet 12 at the top of the box body 10, playing a waterproof role, and the wind deflector 20 and the box body 10 can form a second air outlet 13 communicating with the first air outlet 12 to constitute an air outlet channel located at the top of the box body 10.

[0045] That is to say, the wind deflector 20 of the present application can be firmly welded to the top of the box body 10, playing the roles of waterproofing and forming an air outlet channel.

[0046] In some embodiments, a grille is provided at the bottom of the box body 10 to form an air inlet 11. That is to say, in the present application, a grille can be directly provided on the bottom plate of the box body 10 to form an air inlet 11, which has a simple structure and is easy to manufacture.

[0047] In addition, by selecting appropriate grille materials and structures, it is possible to block external dust and moisture from entering the inside of the electric control box body, protecting the internal equipment from pollution and damage. That is, a reasonable air outlet grille design can also play a role in dust and waterproofing.

[0048] In addition, the grille can also serve as a protective barrier to prevent external objects or small animals from entering the inside of the electric control box body, causing safety hazards such as damage or short circuit to the internal components of the electric control box.

[0049] Furthermore, in some embodiments, a stacked double-layer grille structure 14 is provided at the bottom of the box body 10 to form an air inlet 11.

[0050] That is, the air inlet of the present application can be set as a frame structure of a stacked double-layer grille, which is equivalent to having a double-layer protective barrier, and can further play a role in waterproofing and dustproofing, further ensuring that the internal equipment is protected from pollution and damage.

[0051] Specifically, as Figure 2 shown, the first grille 141 and the second grille 142 of the double-layer grille structure 14 forming the air inlet 11 of the present application can partially overlap, thus playing the role of a double-layer protective barrier, further playing a role in waterproofing and dustproofing, and ensuring that the internal equipment is protected from pollution and damage.

[0052] Among them, the first grille 141 can be a grille layer formed by directly opening a grille at the bottom of the box body 10, and the second grille 142 can be a connection structure fixed below the grille at the bottom of the box body 10. As Figure 1 shown, the double-layer grille structure 14 can also include two connection side plates 143 connecting the ends of the first grille 141 and the ends of the second grille 142. The connection side plates 143 can be fixedly connected to the bottom plate of the box body 10 by screws.

[0053] In some embodiments, both the first air outlet 12 and the second air outlet 13 of the present application are rectangular air outlets. Since the top of the box body of the electric control box 100 is rectangular, and the first air outlet 12 and the second air outlet 13 of the same shape are provided, the area of the air outlet can be maximized, the air volume can be ensured, and a good heat dissipation effect can be achieved.

[0054] In some embodiments, a grille is provided on the top of the box body 10 to form the second air outlet 13. That is to say, in the present application, the second air outlet 13 can also be formed in the form of a grille on the top of the box body 10. While ensuring a relatively large air outlet area of the electric control box 100, it can also play a role in protecting the internal components of the electric control box 100, preventing external objects or small animals from entering the inside of the electric control box body and causing safety hazards such as damage or short circuit to the internal components of the electric control box 100.

[0055] The present application provides an outdoor unit of an air conditioner. The outdoor unit of the air conditioner includes the electric control box 100 described in any of the above embodiments. The structure of the electric control box 100 of the present application is as described above and will not be elaborated here.

[0056] The electric control box 100 in the outdoor unit of the air conditioner of the present application adjusts the air outlet to the top of the box body 10 of the electric control box 100, increasing the air outlet area, reducing the overall occupied space of the electric control box 100. The air duct inside the electric control box 100 flows from bottom to top, with a better air field, increasing the air volume and improving the heat dissipation effect.

[0057] The above embodiments only represent several embodiments of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
