[0036] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0037] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The "first", "second" and similar words used in this application do not represent any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one" or "one" do not represent quantitative limitations. Unless otherwise indicated, similar words such as "front", "rear", "bottom" and / or "upper", "top", "bottom" are only for ease of explanation and are not limited to a position or a spatial orientation.

[0038] The present application provides an electric control box, which is installed inside the device. Figure 1 and Figure 2 The electric control box of the present application includes a body 100 and an electric control main board 200. In addition, the electric control box may also include an electric control box cover 400, which is disposed on the body 100. The body 100 includes a bottom wall. The electric control main board 200 is located inside the body 100, and is combined with the Figure 3 and Figure 4 , the electronic control mainboard 200 includes a first position and a second position. In the first position, the electronic control mainboard 200 is fixed parallel to the bottom wall of the body 100, which can be referred to Figure 3 As shown in FIG. 1 , the position of the electronic control mainboard 200. In the second position, the electronic control mainboard 200 and the bottom wall of the body 100 form a fixed angle, which can be referred to as Figure 4 As shown in the figure, the position of the electronic control main board 200. The electronic control main board 200 is rotatably connected to the body 100, and the electronic control main board 200 is rotated from the first position to the second position. The rotating device can be a guide device, a hinge, a plurality of transmission gears, a bearing, etc. connected between the electronic control main board 200 and the body 100, and the rotatable connecting device is not limited here.

[0039] The electronic control mainboard 200 is provided with various electrical appliances, such as capacitors, transformers, etc. When an electrical appliance on the electronic control mainboard 200 fails, the electronic control mainboard 200 moves from the first position fixed to the body 100 to the second position. When in the second position, the electronic control mainboard 200 and the bottom wall of the body 100 form a fixed angle, and the electronic control mainboard 200 is further away from the body 100 than in the first position. The body 100 is installed inside the device, so the electronic control mainboard 200 in the second position is further away from the inside of the device, and the electronic control mainboard 200 in the second position allows maintenance personnel to repair the electronic control mainboard more conveniently.

[0040] For example, refer to Figure 5 and Figure 6 The electric control box is installed inside the air conditioner. The internal structure of the air conditioner is complex and the maintenance space is limited. It is difficult for maintenance personnel to repair. In this application, when maintenance is needed, the electric control motherboard 200 is removed from the Figure 5 The first position in the Figure 6 In the second position, since the electronic control main board 200 in the second position forms a fixed angle with the main body 100, the electronic control main board 200 is farther away from the main body of the electronic control box and farther away from the interior of the air conditioner, that is, closer to the maintenance personnel, which is convenient for the maintenance personnel to repair the electronic control main board 200.

[0041] The angle between the electric control mainboard 200 and the bottom wall of the body 100 in the second position can be set according to the specific position where the electric control box is installed in the air conditioner and the installation position of the air conditioner. For example, the electric control box is installed on the bottom wall of the air conditioner, and the air conditioner is hung on the top wall of the room. In this use state, the fixed angle can be 90 degrees. When maintenance is required, the maintenance personnel rotate the electric control mainboard 200 from the first position to the second position. When the electric control mainboard 200 is in the second position, the maintenance personnel raise their heads and face the top wall of the room, and can directly see the electric control mainboard 200, which is convenient for maintenance. In addition, if the air conditioner is suspended on the side wall of the room, and the electric control box is also installed on the bottom wall inside the air conditioner, in this state, the fixed angle can also be 180 degrees. The electric control mainboard 200 is rotated to the outside of the air conditioner, and the maintenance personnel raise their heads and can directly see the electric control mainboard 200. Therefore, the setting of the fixed angle can be determined according to the actual installation state of the air conditioner and the installation position of the electric control box, so as to facilitate the maintenance personnel to repair the electric control box.

[0042] In one embodiment, in combination Figures 2 to 4, the electric control box also includes a first component 310 and a second component 320. The electric control mainboard 200 includes a fixed end 210 and a movable end 220. The fixed end 210 is detachably connected to the body 100 through the first component 310, and the movable end 220 is rotatably connected to the body 100 through the second component 320. In the first position, the electric control mainboard 200 separates the fixed end 210 from the body through the first component 310, and rotates the electric control mainboard 200 to the second position through the second component 320. When the electric control mainboard 200 does not need to be repaired, it is located in the first position and fixed on the body 100. When it needs to be repaired, before rotating to the second position, the fixed end 210 needs to be separated from the body 100 before the electric control mainboard 200 can be movable. Therefore, the first component 310 needs to be detachable to ensure the fixation and separation of the electric control mainboard 200 and the body 100. The specific detachable device can be a mutually matching threaded connector, a clamping member, a latch, a spring pin, etc.

[0043] In one embodiment, please combine Figure 7 The second component 320 includes a first bracket 321 fixed to the body 100 and a first stopper 322 connected to the electronic control mainboard 200;

[0044] The first bracket 321 is provided with a first guide rail 321a, and the first position-limiting member 322 is inserted in the first guide rail 321a and configured to slide along the first guide rail 321a. The first guide rail 321a includes an arc-shaped guide rail 3211; along the arc-shaped guide rail 3211, the electric control mainboard 200 follows the first position-limiting member 322 and rotates from the first position to the second position. In the second position, the fixed angle between the electric control mainboard 200 and the body 100 is consistent with the center angle of the arc-shaped guide rail 3211. The two ends of the arc-shaped guide rail 3211 are respectively the positions where the first position-limiting member 322 is located when the electric control mainboard 200 is located in the first position and the second position. In this embodiment, the rotation of the electric control mainboard 200 is realized by the position-limiting cooperation between the arc-shaped guide rail 3211 and the first position-limiting member 322. In addition, the guide rail rotation method can ensure that the rotating device stops at the set position, providing more accurate positioning. In addition, the friction resistance is small, and the rotation process is more stable. The arc guide rail 3211 has a certain radius. When the electric control mainboard 200 rotates, the linear speed of the arc guide rail 3211 is slower than that of rotating at the center of the circle, thereby reducing the inertial impact during the movement.

[0045] In one embodiment, please combine Figure 7 , the electric control main board 200 also includes a third position, and at the third position and the second position, the extension direction of the electric control main board 200 is located in the same straight line;

[0046] The electric control mainboard 200 in the third position is farther away from the main body 100 than the electric control mainboard 200 in the second position. That is, the electric control mainboard 200 in the third position is farther away from the main body 100, which can further facilitate maintenance. For example, the electric control mainboard 200 is arranged inside the air conditioner. After rotating to the second position, the electric control mainboard 200 is moved away from the main body 100, so that the side of the electric control mainboard 200 close to the main body 100 can be separated from the main body 100. When the side of the electric control mainboard 200 close to the main body 100 needs to be repaired, this embodiment can alleviate the problem of cramped maintenance space due to the obstruction of the main body 100.

[0047] In one embodiment, the first guide rail 321a further includes a first linear guide rail 3212, which is connected to the arc-shaped guide rail 3211; along the first linear guide rail 3212, the electric control mainboard 200 slides from the second position to the third position along the first limiter 322. The use of the same guide rail from the first position to the second position can better match the arc-shaped guide rail 3211, has a simple structure, and can slide to the third position more accurately, ensuring the stability of the sliding process.

[0048] In one embodiment, in combination Figure 7 The first bracket 321 also includes a second guide rail 321b, and the electronic control mainboard 200 is also connected to a second stopper 323, which is inserted into the second guide rail 321b and configured to slide along the second guide rail 321b. The second guide rail 321b includes at least a second linear guide rail, and the extension direction of the second linear guide rail is in the same straight line as the extension direction of the first linear guide rail 3212. Figure 7 In the embodiment, the second linear guide rail is the second guide rail 321b. The second limiter 323 and the first limiter 322 can simultaneously drive the electronic control mainboard 200 to move from the first position to the second position, and then move from the second position to the third position. When there is only one first limiter 322, the electronic control mainboard 200 may swing around the first limiter 322 during the movement. The first bracket 321 may include two brackets, which are respectively arranged on opposite sides of the electronic control mainboard 200.

[0049] In this embodiment, two limiters are used, and the two limiters limit each other, so that the movement process of the electronic control mainboard 200 can be more stable. The second guide rail 321b can only include a second linear guide rail. At this time, one end of the second linear guide rail coincides with the center of the arc guide rail 3211. During the rotation of the first limiter 322 on the arc guide rail 3211, the second limiter 323 rotates in place at one end of the second linear guide rail. In addition, the second guide rail 321b can also include a second arc guide rail and a second linear guide rail. The second arc guide rail and the arc guide rail 3211 of the first guide rail have the same center and the same central angle, but different radii.

[0050] In one embodiment, please refer to Figure 8 The second component 320 is a hinge, and two hinge bases of the hinge are respectively fixed on the electric control main board 200 and the body 100. In this embodiment, the electric control main board 200 and the body 100 can be rotated by the hinge, and the process of rotating from the first position to the second position can be realized. There can be multiple hinges. Specifically, when the electric control box is a plastic part, the second component 320 can adopt the above-mentioned guide rail method, and when the electric control box is a sheet metal part, the second component 320 can adopt the hinge method.

[0051] In one embodiment, in combination Figures 9 to 11 The first limiter 322 is a retractable component and is installed on the electronic control mainboard 200. The first limiter 322 includes a fourth position and a fifth position. In the fourth position, the first limiter 322 is inserted into the first guide rail 321a. Fig. 9 As shown in FIG. 1 , one end of the first stopper 322 extends out of the electronic control mainboard 200 and is inserted into the first guide rail 321a. In the fifth position, the first stopper 322 is flush with the edge of the electronic control mainboard 200. Fig.10 As shown, one end of the first stopper 322 is flush with the electronic control mainboard 200 and will not be inserted on the first guide rail 321a, so that the electronic control mainboard 200 can be separated from the first bracket 321. The first stopper 322 is a retractable component that can be retracted and transformed between the fourth position and the fifth position. Specifically, the first stopper 322 can be limited by a spring. Alternatively, Fig.11 As shown in the figure, the first stopper 322 is a bolt, and a threaded hole is provided on the electric control main board 200. Through the cooperation between the bolt and the threaded hole, the bolt is rotated to realize the expansion and contraction transformation of the first stopper 322 between the fourth position and the fifth position. The electric control main board 200 can be composed of a circuit board and a main board, and the electric control main board 200 can be combined with the circuit board and the main board. Fig.11 The first limiting member 322 can be fixed on the main board, and then fixed to the electronic control main board 200, and drive the electronic control main board 200 to move.

[0052] In one embodiment, please refer to Figure 7, the first guide rail 321a also includes at least two limiting grooves 324, the limiting grooves 324 are used to cooperate with the first limiting member 322, and the two limiting grooves 324 are respectively arranged at the two ends of the first guide rail 321a, and protrude in a direction perpendicular to the extension direction of the first guide rail 321a. Take the first guide rail 321a as an example, including an arc guide rail 3211 and a first linear guide rail 3212 that are connected to each other. The extension direction of one end of the arc guide rail 3211 is the tangent direction of the arc guide rail 3211. Therefore, the protruding direction of the limiting groove 324 is the direction perpendicular to the tangent of the arc guide rail 3211 here. The extension direction of the first linear guide rail 3212 is the direction in which the first linear guide rail 3212 is formed, and a limiting groove 324 is also provided at one end of the first linear guide rail 3212. In the first position and the third position, the first limiting member 322 is respectively clamped on the two limiting grooves 324. The second guide rail 321b may also be provided with a limiting groove, which corresponds to the limiting groove 324 on the first guide rail 321a and has the same protruding direction. In this embodiment, the limiting groove 324 is used for limiting, and the limiting groove 324 can directly cooperate with the first guide rail 321a. When the first limiting member 322 slides to both ends of the first guide rail 321a, it will be directly limited, ensuring precise control of the movement, and the structure is simple and the manufacturing cost is low.

[0053] Specifically, taking the case where the electric control box is installed on the bottom wall of the air conditioner and the air conditioner is suspended on the top of the room as an example, the limit groove 324 at one end of the arc guide rail 3211 can be protruding in the direction away from the arc center, and the limit groove 324 at one end of the first linear guide rail 3212 is facing the floor of the room. That is, the protruding directions of the two limit grooves 324 are opposite. In this way, the movement trajectory of the electric control main board 200 is that the first limit member 322 exits the limit groove 324 at one end of the arc guide rail 3211 at the first position, then rotates along the arc guide rail 3211 to the second position, is pulled to the third position by the first linear guide rail 3212, and finally is clamped into the limit groove 324 at one end of the first linear guide rail 3212 under the action of gravity.

[0054] In another embodiment, please refer to Figure 2 and Fig.12 , the first limiting member 322 is a buckle inserted into the first guide rail 321a. The buckle is made of a flexible material and can be retracted. In the expanded state, it has an interference fit with the first guide rail 321a. The size of the buckle is larger than the size of the guide rail, and the electronic control main board 200 and the first guide rail 321a are limited. In the retracted state, the buckle is squeezed so that the diameter of the buckle is smaller than the first guide rail 321a, and the electronic control main board 200 can move along the first guide rail 321a.

[0055] In one embodiment, the first component 310 is a threaded connector, which passes through the fixed end 210 and the body 100 along a first direction to detachably connect the electronic control mainboard 200 to the body 100, and the first direction is parallel to the extension direction of the bottom wall of the body 100. The threaded connector is arranged along the first direction to facilitate the disassembly of the threaded connector. Figure 3 and Figure 5 , the electronic control main board 200 is installed at the bottom of the air conditioner for illustration. When the threaded connector needs to be removed and the electronic control main board 200 is pulled out, the installation and removal directions of the threaded connector are both in the first direction parallel to the body 100. The maintenance personnel can insert the tool from the outside along the first direction to tighten or loosen the threaded connector. Compared with the installation and removal direction of the threaded connector being perpendicular to the bottom wall, the maintenance personnel need to use tools inside the air conditioner, which not only has a small operating space, but also easily causes improper operation to damage the components inside the air conditioner. Therefore, this embodiment can further facilitate the maintenance personnel to inspect the electronic control box and perform after-sales maintenance.

[0056] Combination Figure 5 and Figure 6 The present application also provides an air conditioner, which may be a household air conditioner or an industrial air conditioner. The air conditioner includes the above-mentioned electric control box, which is arranged on the return air side of the air conditioner. The grille on the return air side of the air conditioner is convenient to disassemble, so that when maintenance personnel inspect the electric control box, they can remove the grille on the return air side and then repair the electric control box.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
