Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, and more specifically, to an electric control box assembly, an air duct structure thereof, an outdoor unit of an air conditioner, and an air conditioner. Background Art

[0002] An electric control box assembly includes a mounting bracket, an electric control board, a plastic electric control box, and a radiator. The mounting bracket is vertically arranged in the front-rear direction. The plastic electric control box is fixed on the right side of the mounting bracket. The electric control board is fixed inside the plastic electric control box from the right side of the plastic electric control box. The radiator is located on the left side of the mounting bracket and passes through the mounting bracket and the plastic electric control box to be connected to the electric control board. The mounting bracket has a first air inlet, an air passage, and a second air inlet that are sequentially communicated from bottom to top. The first air inlet and the air passage are located on the left side of the plastic electric control box. The first air inlet faces downward. The upper part of the radiator is located in the first air inlet, and the lower part of the radiator is located below the first air inlet. The second air inlet is located above the electric control board and faces right. Among them, the left side wall and the right side wall of the air passage are provided with a first water baffle rib plate and a second water baffle rib plate arranged in the horizontal direction. The first water baffle rib plate and the second water baffle rib plate are spaced up and down and offset left and right, and are used to block the water entering the air passage from the first air inlet from moving towards the second air inlet.

[0003] However, during the process of air blowing from the second air inlet along the air passage towards the first air inlet, the first water baffle rib plate located below generates a relatively large air resistance to the air beam, which is not conducive to the smooth passage of air through the air passage and will reduce the heat dissipation effect of the radiator.

[0004] An embodiment of the utility model provides an air duct structure of an electric control box assembly, including: a vertically arranged mounting bracket, the mounting bracket having a first air inlet, an air passage, and a second air inlet, the first air inlet being located below the second air inlet and being connected to the second air inlet through the air passage, and an upwardly inclined first water blocking part being arranged inside the air passage, the first water blocking part being located between the first air inlet and the second air inlet and being arranged to block water.

[0005] In some exemplary embodiments, there are multiple first water blocking parts, and the multiple first water blocking parts are spaced at intervals in the horizontal direction and have an overlapping area in the projection on the horizontal plane.

[0006] In some exemplary embodiments, the horizontal direction includes a first horizontal direction. The side surface of each of the first water blocking portions is inclined with respect to the up-down direction and the first horizontal direction, and the inclination angle of the side surface of each of the first water blocking portions with respect to the vertical plane perpendicular to the first horizontal direction is 15 degrees to 45 degrees. A plurality of the first water blocking portions are arranged at intervals in the first horizontal direction in sequence. The projections of adjacent first water blocking portions on the horizontal plane have a first overlapping area. The size of each first overlapping area in the first horizontal direction is not less than 3 mm, and the overlapping area includes all of the first overlapping areas.

[0007] In some exemplary embodiments, the first water blocking portion is provided with air passing holes, and there are a plurality of the air passing holes. The diameter of each air passing hole is 1 mm to 5 mm.

[0008] In some exemplary embodiments, a second water blocking portion is further provided inside the air passing channel. The second water blocking portion is located between the first air passing opening and the second air passing opening, is vertically spaced and horizontally offset from the first water blocking portion, and is arranged to block water.

[0009] In some exemplary embodiments, the second water blocking portion is arranged obliquely above the first water blocking portion in the first horizontal direction and is fixedly connected to the first water blocking portion on the side walls of the air passing channel that are opposite to each other in the second horizontal direction. The projections of the second water blocking portion and the first water blocking portion on the horizontal plane have a second overlapping area. The size of the second overlapping area in the second horizontal direction is not less than 2 mm, and the first horizontal direction and the second horizontal direction intersect perpendicularly.

[0010] In some exemplary embodiments, the mounting bracket includes: a first plate standing upright, with a second air passing opening provided on its side surface; and a second plate, which is arranged on the side surface of the first plate and encloses the air passing channel and the first air passing opening together with the first plate. The air passing channel is arranged upright, and the first air passing opening faces downward.

[0011] An embodiment of the present invention further provides an electric control box assembly, which includes an electric control board, a radiator, and the air duct structure of the electric control box assembly according to any one of the above embodiments. The mounting bracket is provided with an avoidance opening, and the avoidance opening is located below the second air passing opening. The electric control board is arranged on the first side of the mounting bracket and is below the second air passing opening. The second air passing opening is communicated with the first side of the mounting bracket. The air passing channel is located on the second side of the electric control board. The first air passing opening is communicated with the second side of the mounting bracket. The radiator is correspondingly arranged with the first air passing opening and is connected to the electric control board at the avoidance opening.

[0012] An embodiment of the present utility model further provides an outdoor unit of an air conditioner, which includes a housing, a middle partition board, and the electric control box assembly described in any one of the above embodiments.

[0014] In the air duct structure of the electric control box assembly provided by the embodiment of the present utility model, the first water blocking portion is inclined upward from bottom to top in the air passage. In this way, when air is blown from the second air passage opening along the air passage towards the first air passage opening, the air flow will be blown obliquely downward along the side surface of the first water blocking portion. In this solution, the wind resistance generated by the first water blocking portion on the air flow is relatively small, which is beneficial to the smooth passage of air through the air passage. Therefore, the heat dissipation effect of the radiator of the electric control box assembly is better.

[0015] Moreover, when the first water blocking rib plate in the related art is replaced with the first water blocking portion of the present application, and the projected areas of the two on the horizontal plane are the same, the water blocking effect of the first water blocking portion of the present application is basically the same as that of the first water blocking rib plate in the related art.

Specific implementation manners

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0026] The electric control box assembly provided by the embodiment of the present utility model, as Figures 1 to 3 shown, includes an electric control board 100, a radiator 200 and the air duct structure of the electric control box assembly. As Figures 1 to 5 shown, the air duct structure of the electric control box assembly includes: a vertically arranged mounting bracket 300, the mounting bracket 300 having a first air passage opening 330, an air passage 340 and a second air passage opening 311, the first air passage opening 330 being located below the second air passage opening 311 and being connected to the second air passage opening 311 through the air passage 340, a first water blocking part 321 inclined upward from bottom to top being provided inside the air passage 340, the first water blocking part 321 being located between the first air passage opening 330 and the second air passage opening 311 and being configured to block water. The mounting bracket 300 is provided with an avoidance opening, the avoidance opening being located below the second air passage opening 311, the electric control board 100 being disposed on the first side (such as the right side) of the mounting bracket 300 and being below the second air passage opening 311, the second air passage opening 311 being connected to the first side of the mounting bracket 300, the air passage 340 being located on the second side (such as the left side) of the electric control board 100, the first air passage opening 330 being connected to the second side of the mounting bracket 300, and the radiator 200 being correspondingly arranged with the first air passage opening 330 and being connected to the electric control board 100 at the avoidance opening.

[0027] Under the negative pressure suction on the second side of the electronic control box assembly, the air near the electronic control board 100 is blown from the second air vent 311 along the air passage 340 through the first air vent 330 to the radiator 200, so as to dissipate heat from the radiator 200. The water on the second side of the electronic control box assembly splashes into the air passage 340 from the first air vent 330, and the first water blocking part 321 blocks the water splashing into the air passage 340 from the first air vent 330 from moving towards the second air vent 311.

[0028] For this electronic control box assembly, as Figure 4 shown, the first water blocking part 321 is inclined upward from bottom to top in the air passage 340. In this way, during the process that the air is blown from the second air vent 311 along the air passage 340 to the first air vent 330, the air beam will be blown obliquely downward along the side surface of the first water blocking part 321. In this solution, the wind resistance generated by the first water blocking part 321 on the air beam is small, which is beneficial to the smooth passage of the air through the air passage 340 and blowing towards the radiator 200. Therefore, the heat dissipation effect of the radiator 200 is better.

[0029] Moreover, when the first water blocking rib plate in the related technology is replaced with the first water blocking part 321 of the present application, and their projected areas on the horizontal plane are the same, the water blocking effect of the first water blocking part 321 of the present application is basically the same as that of the first water blocking rib plate in the related technology.

[0030] In some embodiments, as Figure 3 and Figure 4 shown, there are multiple first water blocking parts 321. The multiple first water blocking parts 321 are arranged at intervals in the horizontal direction and their projections on the horizontal plane have overlapping areas. In this way, the air beam can pass through the multiple first water blocking parts 321 more smoothly and blow towards the radiator 200 in a larger amount, and the overlapping areas also improve the water blocking effect of the multiple first water blocking parts 321.

[0031] In one embodiment, as Figure 4As shown in the figure, the horizontal direction includes a first horizontal direction (such as the front-rear direction). The side surface of each first water retaining portion 321 is inclined with respect to the up-down direction and the first horizontal direction (that is, each first water retaining portion 321 is arranged vertically in the left-right direction, and the side surface of each first water retaining portion 321 is inclined forward from bottom to top or the side surface of each first water retaining portion 321 is inclined backward from bottom to top). And the inclination angle a of the side surface of each first water retaining portion 321 with respect to the vertical plane perpendicular to the first horizontal direction is 15 degrees to 45 degrees (that is, the inclination angle of the side surface of each first water retaining portion 321 inclined forward from bottom to top is 15 degrees to 45 degrees or the inclination angle of the side surface of each first water retaining portion 321 inclined backward from bottom to top is 15 degrees to 45 degrees). A plurality of first water retaining portions 321 are arranged at intervals in the first horizontal direction in sequence. The projections of adjacent first water retaining portions 321 on the horizontal plane (that is, in the front-rear direction) have a first overlapping area (that is, a plurality of first water retaining portions 321 project a complete water retaining surface on the horizontal plane). And the size b of each first overlapping area in the first horizontal direction is not less than 3 mm. The overlapping area includes all the first overlapping areas. In this solution, a plurality of first water retaining portions 321 not only have a small wind resistance to the wind beam, but also have a good effect of blocking water.

[0032] In one embodiment, as Figure 4 shown, the size b of each first overlapping area in the first horizontal direction is set to 10 mm. In this way, the water splashing into the air passage 340 from the first air passing opening 330 is less likely to pass between a plurality of first water retaining portions 321.

[0033] In some embodiments, as Figure 3 and Figure 5 shown, the first water retaining portion 321 is provided with air passing holes 322. There are a plurality of air passing holes 322. The diameter of each air passing hole 322 is 1 mm to 5 mm. In this way, the wind beam is more likely to pass through the first water retaining portion 321, and the first water retaining portion 321 generates less wind resistance to the wind beam. And the inclination angle of the side surface of each first water retaining portion 321 with respect to the vertical plane perpendicular to the first horizontal direction (that is, the vertical plane formed by the up-down direction and the left-right direction) is 15 degrees to 45 degrees. In this way, the width of the projection area of the air passing holes 322 on the horizontal plane is very small, and the water splashing into the air passage 340 from the first air passing opening 330 can be prevented from passing through the air passing holes 322. The first water retaining portion 321 in this solution not only has the function of blocking water, but also has a small wind resistance to the wind beam blown in the air passage. It can be that a plurality of air passing holes 322 cover the side surface of the first water retaining portion 321.

[0034] In one embodiment, as Figure 3 and Figure 5As shown, the diameter of each air passage hole 322 is set to 3 mm, and the inclination angle of the side surface of the first water blocking portion 321 relative to the vertical plane perpendicular to the first horizontal direction (i.e., the vertical plane formed by the up-down direction and the left-right direction) is set to 22 degrees. In this way, the width of the projection area of the air passage hole 322 on the horizontal plane is very small, and the water splashing into the air passage 340 from the first air inlet 330 can hardly pass through the air passage hole 322.

[0035] In some examples, such as Figure 3 As shown, a second water blocking portion 312 is further provided inside the air passage 340. The second water blocking portion 312 is located between the first air inlet 330 and the second air inlet 311, and is vertically spaced and horizontally misaligned with the first water blocking portion 321. The second water blocking portion 312 is configured to block water. In this solution, the second water blocking portion 312 and the first water blocking portion 321 form a bent labyrinth passage inside the air passage 340. The labyrinth passage can better block the water splashing into the air passage 340 from the first air inlet 330 from reaching the second air inlet 311. Therefore, the water splashing into the air passage 340 from the first air inlet 330 is less likely to pass through the second air inlet 311 and reach the electronic control board 100. Thus, the waterproof effect of the electronic control board 100 is better.

[0036] In some embodiments, such as Figure 3 As shown, the second water blocking portion 312 is arranged obliquely above the first water blocking portion 321 along the first horizontal direction, and is fixedly connected to the first water blocking portion 321 on the opposite side walls of the air passage 340 in the second horizontal direction (such as the left-right direction). Moreover, the projections of the second water blocking portion 312 and the first water blocking portion 321 on the horizontal plane have a second overlapping area, and the dimension c of the second overlapping area in the second horizontal direction is not less than 2 mm. In this solution, the projections of the second water blocking portion 312 and the first water blocking portion 321 on the horizontal plane are continuous in the second horizontal direction. In this way, the water splashing into the air passage 340 from the first air inlet 330 is less likely to reach the second air inlet 311, and the waterproof effect of the electronic control board 100 is better.

[0037] In one embodiment, such as Figure 3 As shown, the dimension c of the second overlapping area in the second horizontal direction is set to 4 mm. In this way, the water blocking effect of the first water blocking portion 321 and the second water blocking portion 312 is better, and the water splashing into the air passage 340 from the first air inlet 330 cannot pass through the first water blocking portion 321 and the second water blocking portion 312 to reach the second air inlet 311. Therefore, the water splashing into the air passage 340 from the first air inlet 330 is even less likely to pass through the second air inlet 311 and reach the electronic control board 100.

[0038] Of course, it is also possible that the second water retaining part 312 is inclined upward from bottom to top (this solution is not shown in the figure), the number of the second water retaining parts 312 can be set to one, or the number of the second water retaining parts 312 can be set to multiple ones spaced apart in the front and rear directions, the second water retaining part 312 can be arranged above the first water retaining part 321, or the second water retaining part 312 can be arranged below the first water retaining part 321 (this solution is not shown in the figure). The above can all achieve the purpose of this application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of this application.

[0039] In some examples, as Figures 1 to 3 shown, the mounting bracket 300 includes: a vertically arranged first bracket plate 310, and a second air passing opening 311 is arranged on the side surface of the first bracket plate 310; and a second bracket plate 320, the second bracket plate 320 is arranged on the left side of the first bracket plate 310 and encloses an air passing channel 340 and a first air passing opening 330 together with the first bracket plate 310. The air passing channel 340 is vertically arranged, and the first air passing opening 330 faces downward (the second bracket plate 320 is a groove member with a notch facing right and a lower side penetrating). A first water retaining part 321 is arranged on the side surface of the second bracket plate 320 facing the first bracket plate 310, and a second water retaining part 312 is arranged on the side surface of the first bracket plate 310 facing the second bracket plate 320.

[0040] Among them, as Figure 4 and Figure 5 shown, a plurality of first folded plates are fixedly arranged on the side surface of the second bracket plate 320 facing the first bracket plate 310 in an inclined manner from bottom to top. The plurality of first folded plates are sequentially spaced apart in the front and rear directions. The left plate segment of each first folded plate is fixedly connected to the side surface of the second bracket plate 320 facing the first bracket plate 310 (such as welded connection or screw connection), and the right plate segment of each first folded plate forms the first water retaining part 321. As Figure 3 shown, a second folded plate is arranged on the side surface of the first bracket plate 310 facing the second bracket plate 320 in the front and rear directions. The right plate segment of the second folded plate is fixedly connected to the side surface of the first bracket plate 310 facing the second bracket plate 320 (such as welded connection or screw connection), and the left plate segment of the second folded plate forms the second water retaining part 312.

[0041] In an embodiment, the electric control box assembly further includes a plastic electric control box 400. The plastic electric control box 400 is fixed on the first side of the mounting bracket 300. The electric control board 100 is located on the side of the plastic electric control box 400 facing away from the mounting bracket 300 and is fixed on the plastic electric control box 400.

[0042] The outdoor unit of the air conditioner (not shown in the figure) provided by the embodiment of the present utility model includes a housing, a middle partition board, and the electric control box assembly described in any one of the above embodiments. The middle partition board is arranged inside the housing and divides the interior of the housing into a heat exchange chamber and an installation chamber. An installation opening is provided on the side surface of the middle partition board, and the electric control box assembly is arranged at the installation opening. The electric control board 100 is located in the installation chamber, and the radiator 200, the first air passage opening 330, and the air passage 340 are located in the heat exchange chamber.

[0043] This outdoor unit of the air conditioner has all the advantages of the electric control box assembly provided in any one of the above embodiments, which will not be elaborated here.

[0044] Wherein, a heat exchanger and a fan assembly are fixed in the heat exchange chamber. The fan assembly is located on the front side of the heat exchanger. When the fan assembly operates, under the negative pressure suction between the fan assembly and the heat exchanger, the air near the electric control board 100 in the installation chamber is blown from the second air passage opening 311 along the air passage 340 through the first air passage opening 330 to the radiator 200, and finally blown out forward from the front part of the heat exchange chamber.

[0045] The air conditioner provided by the embodiment of the present utility model (not shown in the figure) includes the outdoor unit of the air conditioner described in any one of the above embodiments.

[0046] This air conditioner has all the advantages of the outdoor unit of the air conditioner provided in any one of the above embodiments, which will not be elaborated here.

[0047] To sum up, for the electric control box assembly provided by the embodiment of the present utility model, the first water blocking part is inclined upward from bottom to top in the air passage. In this way, when the air is blown from the second air passage opening along the air passage to the first air passage opening, the air flow will be blown obliquely downward along the side surface of the first water blocking part. In this solution, the wind resistance generated by the first water blocking part on the air flow is small, which is beneficial to the smooth passage of air through the air passage and blowing to the radiator. Therefore, the heat dissipation effect of the radiator is better.

[0048] Moreover, when the first water blocking rib plate in the related art is replaced with the first water blocking part of the present application and their projected areas on the horizontal plane are the same, the water blocking effect of the first water blocking part of the present application is basically the same as that of the first water blocking rib plate in the related art.
