Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0024] As Figures 1 to 11 shown, the present application provides an electric control box applied to an air conditioner, comprising an electric control box body 10 rotatably arranged on the body of the air conditioner. The electric control box body 10 is rotatably mounted, specifically, under normal circumstances, the box body is still fixed on the body to ensure a certain installation firmness, when the structure on the back of the electric control box body 10 (which can be the structure of the electric control box body 10 itself, or the structure on the body which is blocked by the electric control box body 10) needs to be repaired or replaced, only the partial fixing structure between the electric control box body 10 and the body needs to be disassembled, and then the electric control box body 10 is rotated relative to the body by a certain angle, without the need to disassemble more structures, so that the operation is simple, the work efficiency is high, and the adverse effects on the surrounding structures can be avoided.
[0025] Among them, the electric control box body 10 is provided with a first refrigerant pipeline 11, one end of the first refrigerant pipeline 11 is provided with a first connector 12, the first connector 12 protrudes downward relative to the bottom of the electric control box body 10; the air conditioner is provided with a second refrigerant pipeline, one end of the second refrigerant pipeline is provided with a second connector 13; the first connector 12 and the second connector 13 are connected through a pre-shaped hose 14.
[0026] As Figure 5 and Figure 6As shown, the first joint 12 is at least partially located below the electric control box 10, and the end of the hose 14 connected to the first joint 12 is located below the electric control box 10 and is not blocked by the electric control box 10. Therefore, even if the electric control box 10 is not rotated, the connection or disconnection of the pipeline between the first joint 12 and the second joint 13 can be conveniently performed. Especially, when the electric control box 10 is rotatably arranged, the structure of the hose 14 can be affected after the electric control box 10 is rotated for multiple times, and the pipeline can be blocked or damaged. At this time, the hose 14 can be conveniently and quickly replaced, so as to ensure the heat dissipation effect of the refrigerant on the electric control box 10. In addition, for the electric control box 10 fixed on the upper end of the machine body, the first joint 12 is led out from the bottom of the electric control box 10, so that the straight-line distance between the first joint 12 and the second joint 13 of the air conditioner is shorter, and the overall length requirement of the hose 14 is reduced. The deformation range of the shorter hose 14 is smaller during rotation, and the risk of damage caused by excessive stretching or bending is reduced. Moreover, the first joint 12 is arranged protruding from the bottom of the box, so that the connection point of the hose 14 is closer to the fixed end (the second joint 13) of the equipment. During rotation of the box, the stress direction of the hose 14 is more inclined to swing along the axis itself, rather than complex twisting or folding, which reduces the stress concentration at the joint of the hose 14, improves the connection sealing performance and stability. On this basis, during the rotation process of the electric control box 10, the first joint 12 and the hose 14 can avoid colliding or rubbing with other parts of the air conditioner, so as to ensure that there is no mechanical obstruction during rotation, and improve the smoothness of rotation. Moreover, the circumferential movement radius of the first joint 12 during rotation can be reduced, and the space redundancy required during rotation is reduced. Especially in the scene of a multi-split unit and the like with a compact space, the problem of insufficient operation space caused by excessive rotation radius can be effectively avoided.
[0027] Further, the hose 14 with a preset shape is used to connect the first joint 12 and the second joint 13. The hose 14 with a preset shape can accurately match the movement track of the electric control box 10 during rotation. During the rotation process of the box, the hose 14 can flexibly deform along the preset path, avoid hindering rotation due to excessive rigidity, or pulling the box due to insufficient flexibility, and ensure that the rotation angle is not limited. The specific shape design can make the hose 14 maintain uniform deformation ability at different rotation angles, avoid excessive tension or folding at a certain angle, eliminate the jamming feeling during rotation, and improve the operation convenience. The preset shape of the hose 14 can make the two end joints always maintain a reasonable stress posture during rotation, reduce the relative displacement of the joint and the connection position of the hose 14, reduce the risk of sealing failure caused by deformation, and protect the refrigerant from leakage.
[0028] Exemplarily, as shown in FIG. 6, the first joint 12 is arranged on the bottom of the electric control box 10, and the second joint 13 is arranged on the upper end of the machine body. The hose 14 is arranged to connect the first joint 12 and the second joint 13. The hose 14 is arranged to be flexible and has a preset shape. The preset shape of the hose 14 is matched with the movement track of the electric control box 10 during rotation. Figure 3 and Figure 4As shown, the hose 14 adopts an S-shaped hose 14. The continuous bending characteristic of the S-shaped hose 14 can form two-directional elastic buffer zones. When the electric control box body 10 rotates clockwise or counterclockwise around the rotation axis, the hose 14 can absorb the rotation displacement by synchronous deformation of the two bending sections, avoid excessive stretching or compression on one side, and ensure that the hose 14 is always in a stable stress state during rotation. The smooth curve design of the S-shaped hose 14 makes the deformation of the hose 14 more uniform during rotation, and does not cause a jamming feeling due to local hard folding. Even at a large rotation angle (such as 90° or more), the hose 14 can still adapt to the trajectory change by curve expansion or contraction, ensuring smooth rotation of the electric control box body 10 without obstacles. In addition, the continuous bending structure of the S-shaped hose 14 disperses the tension and torsion generated by rotation to the entire curve section, avoiding stress concentration at a fixed point (such as the joint connection), reducing the risk of hose 14 cracking and aging after long-term use, and prolonging the service life.
[0029] In other examples, as shown in Figure 1 and Figure 2 , the hose 14 can adopt a U-shaped hose 14. The bottom bending section of the U-shaped hose 14 forms a natural length redundancy. When the electric control box body 10 rotates, the hose 14 can compensate for the displacement change caused by rotation by expansion or contraction of the U-shaped bottom, which can be suitable for scenarios that require a large range of rotation (such as 180°), avoiding the limitation of rotation angle due to insufficient length. The large bending radius of the bottom of the U-shaped structure can reduce the risk of wrinkles or breaks on the inner wall of the hose 14 due to excessive bending. Even during frequent rotation, the bottom bending section can maintain a relatively stable shape, reducing the probability of refrigerant leakage.
[0030] In yet other examples, the hose 14 can adopt a composite shape, such as S-shaped plus U-shaped or U-shaped plus S-shaped, without limiting the shape of the hose 14 connected to the first joint 12 and the second joint 13. This embodiment can combine the advantages of different shaped hoses 14 to improve the smoothness of the electric control box body 10 rotation, prolong the service life of the hose 14, optimize space utilization, and solve the contradictory problem that traditional hoses 14 either cannot rotate or are easily damaged in a compact environment.
[0031] The first joint 12 and the second joint 13 are each provided with two to form a circulating loop of the refrigerant. Among them, the hose 14 between one way of the first joint 12 and the second joint 13 can adopt any one of the above-mentioned forms of the hose 14, and the hose 14 between the other way of the first joint 12 and the second joint 13 can adopt any one of the above-mentioned forms of the hose 14, which is not limited by the present application.
[0032] As shown in Figure 6As shown, the first refrigerant pipe 11 is fixed to the back of the electrical control box 10, for example. The layout of the first refrigerant pipe 11 is set according to actual needs. The first connector 12 can be fixed to the back of the electrical control box 10 near the bottom through its upper end, and the lower end of the first connector 12 protrudes downward for connecting the hose 14.
[0033] In a preferred embodiment of the present invention, the body includes a mounting crossbeam 15 and a mounting vertical beam 16; a fixing component is provided between the electrical control box 10 and the mounting crossbeam 15, and a rotating structure is provided between the electrical control box 10 and the mounting vertical beam 16, wherein the electrical control box 10 is rotatable around the mounting vertical beam 16.
[0034] like Figure 5 As shown, when the electrical control box 10 does not need to rotate, it is fixed to the mounting beam 15, ensuring normal installation and use. When repair or replacement of the structure on the back of the electrical control box 10 is required, the fixing structure between the electrical control box 10 and the mounting beam 15 can be removed, and then the electrical control box 10 can be rotated. A rotating structure is provided between the electrical control box 10 and the mounting beam 16; exemplarily, the rotating structure is a hinge 17, such as... Figure 5 In this configuration, two hinges 17 are vertically spaced between the electrical control box 10 and the mounting beam 16 to ensure the connection strength and rotational stability of the electrical control box 10. When the electrical control box 10 rotates, it rotates relative to the mounting beam 16 around the pivot of the hinge 17. It is understood that the rotating structure is not limited to the aforementioned hinge 17, but can also be other pivot and shaft hole mating structures.
[0035] In some embodiments, the top of the electrical control box 10 is provided with a top mounting plate 18, and a driving assembly is provided between the top mounting plate 18 and the mounting beam 15 for driving the electrical control box 10 to rotate around the mounting vertical beam 16.
[0036] like Figure 5As shown, the top hanging plate 18 is provided with a plurality of spaced screw holes 19, which can be fixedly connected with the mounting beam 15 through screws. That is, the top hanging plate 18 and the mounting beam 15 are provided with a fixing assembly, which includes the screw holes 19 and screws, for fixing the electric control box 10 when the electric control box 10 does not rotate. The top hanging plate 18 and the mounting beam 15 are also provided with a driving assembly, which can realize automatic rotation control of the electric control box 10. That is, manual operation only needs to disassemble part of the screws, which can greatly save the amount of manual operation and reduce labor costs. For old maintenance personnel or female operators, there is no need to exert force to flip over a heavy box, which reduces the operation threshold and is conducive to precise control of the rotation angle of the electric control box 10. The uniform rotation driven by electricity replaces manual rapid force, reduces fatigue damage of the hose 14 and wire harness caused by sudden stress, and can also cooperate with an angle sensor to monitor the position in real time, automatically stop when exceeding the limit, and prevent joints from falling off or pipelines from being broken due to excessive rotation.
[0037] In some embodiments, the driving assembly includes a motor 20, a worm 21 connected with the motor 20, and a pushing bracket 22 in transmission cooperation with the worm 21. The motor 20 drives the worm 21 to rotate, and the worm 21 pushes the pushing bracket 22 to move away from the motor 20 to push the electric control box 10 to rotate outward around the mounting vertical beam 16.
[0038] As shown in Figure 7 and Figure 8 , under normal circumstances, the driving assembly is arranged along the extension direction (transverse direction) of the top hanging plate 18 and the mounting beam 15, and the motor 20 is installed at one end of the driving assembly away from the mounting vertical beam 16. The worm 21 and the pushing bracket 22 can be in transmission cooperation through a threaded structure. For example, one end of the worm 21 close to the motor 20 penetrates the pushing bracket 22, the worm 21 is provided with external threads, and the pushing bracket 22 is provided with internal threads. When the electric control box 10 needs to be maintained, the motor 20 rotates in a first direction (e.g., forward rotation) to drive the worm 21 to rotate, the external threads of the worm 21 interact with the internal threads of the pushing bracket 22, thereby driving the pushing bracket 22 to move away from the motor 20, and thus pushing the electric control box 10 to rotate outward around the rotating shaft of the hinge 17, so as to expose the back of the electric control box 10, thereby facilitating maintenance or replacement of parts. When the maintenance is completed, the motor 20 rotates in a second direction (e.g., reverse rotation) to drive the pushing bracket 22 to move close to the motor 20, and the electric control box 10 rotates inward around the rotating shaft of the hinge 17, thereby realizing the reset of the electric control box 10. In order to improve the rotation accuracy, the lengths of the worm 21 and the pushing bracket 22 can be optimized to realize that the electric control box 10 can rotate outward by different angles.
[0039] In some embodiments, the top mounting plate 18 is recessed on the side facing the mounting beam 15 in a direction away from the mounting beam 15 to form a first groove 23 extending laterally, and the mounting beam 15 is recessed on the side facing the top mounting plate 18 in a direction away from the top mounting plate 18 to form a second groove 24 extending laterally, and the first groove 23 and the second groove 24 together form a mounting cavity for mounting the drive assembly.
[0040] like Figure 8 and Figure 10 As shown, the drive assembly can be partially housed in the first groove 23 and partially housed in the second groove 24. The drive assembly is set in the mounting cavity formed by the top mounting plate 18 and the mounting beam 15. On the one hand, there is no need to design a separate external mounting bracket for the drive assembly or a mounting space protruding from the equipment body, which can improve space utilization and achieve a compact design. Moreover, the mounting cavity is far away from the refrigerant pipes, wiring harnesses, motherboards and other core components inside the electrical control box 10, which can avoid spatial interference between the drive assembly and other components and ensure a more orderly layout of each component. On the other hand, the drive assembly is fixed in the mounting cavity, and its force can be simultaneously transmitted to both the top mounting plate 18 and the mounting beam 15, avoiding the risk of loosening caused by single-point force when using traditional single-bracket installation. By confining the drive assembly in a closed space, direct collisions between external tools and parts and the drive assembly can be avoided during equipment assembly, transportation or maintenance. At the same time, it reduces the direct fall of dust and impurities in the air into the motor 20, reducing jamming failures caused by foreign objects. It also reduces the direct contact of water vapor and oil stains with the metal parts of the drive assembly, reducing the risk of corrosion and short circuits.
[0041] Furthermore, the drive assembly also includes a first pin 25 and a second pin 26, wherein the first pin 25 passes through the end of the push bracket 22 away from the motor 20 and vertically penetrates the side wall of the first groove 23; The second pin 26 passes through the motor 20 and vertically through the side wall of the second groove 24.
[0042] like Figure 8 and Figure 10 As shown, the drive assembly is fixed by two pins. The first pin 25 and the second pin 26 can be formed by two pin structures. The drive assembly is hinged to the top mounting plate 18 via the first pin 25, and to the mounting beam 15 via the second pin 26. When maintenance of the drive assembly is required, only one of the first pin 25 and the second pin 26 needs to be removed. It is understood that the electrical control box 10 can also be rotated manually by removing either the first pin 25 or the second pin 26.
[0043] In order to realize the power supply of the motor 20, in some embodiments, the motor 20 is powered by connecting the power supply line; in other embodiments, the motor 20 can be powered by a battery, which can store electricity by driving the fan with natural wind, or can be supplemented with electricity by charging, according to the actual demand.
[0044] In the case that the electric control box 10 does not rotate, in order to improve the installation strength of the electric control box 10, in some embodiments, as shown in Figure 5 The top of the electric control box 10 is provided with a top hanging plate 18, and the top hanging plate 18 and the installation beam 15 are provided with a fixing assembly; one side of the electric control box 10 is provided with a first reinforcing plate 27, and the first reinforcing plate 27 and the installation vertical beam 16 are provided with the rotating structure; the other side of the electric control box 10 is provided with a second reinforcing plate 28, and the second reinforcing plate 28 and the machine body are provided with a fixing assembly. The fixing assembly, for example, includes a plurality of screw holes 19 provided on the top hanging plate 18 and the second reinforcing plate 28 and a plurality of screws installed one by one corresponding to the plurality of screw holes 19, which can increase the installation firmness of the box. The first reinforcing plate 27 and the installation vertical beam 16 are provided with a hinge 17, which provides conditions for the rotation of the electric control box 10. Specifically, the two leaves of the hinge 17 are fixed by screws respectively with the first reinforcing plate 27 and the installation vertical beam 16.
[0045] As a preferred embodiment of the present application, as shown in Figure 11 The bottom of the electric control box 10 is provided with a strong current terminal group 29 and a weak current terminal group 30, and the strong current terminal group 29 and the weak current terminal group 30 are arranged at intervals. By arranging the strong current terminal group 29 and the weak current terminal group 30 at intervals, all strong current wires in the electric control box 10 are connected with the strong current terminal group 29, and all weak current wires are connected with the weak current terminal group 30. By separating strong and weak currents, signal interference can be reduced and use safety can be improved.
[0046] Further, the strong current terminal group 29 and the weak current terminal group 30 each include an upper box body and a lower box body spliced together, the upper box body is fixed with the bottom plate of the electric control box 10, and the lower box body is detachably installed with the upper box body. Specifically, a plurality of upper terminals for connecting with the wire harness in the electric control box 10 are arranged in the upper box body, and a plurality of lower terminals for connecting with external wire harness are arranged in the lower box body, and the upper terminals and the lower terminals are inserted and matched. A sealing structure is formed between the upper box body and the lower box body, which is beneficial to waterproof protection and improves signal transmission reliability. In order not to hinder the rotation of the electric control box 10 and improve the rotation effect of the electric control box 10, the lower box body can be detached before the electric control box 10 rotates, so as to avoid that part of the wire harness on the lower box body falls off from the lower terminal during the rotation process, and the subsequent need to re-install may increase the risk of wrong connection.
[0047] Of course, it can be understood that in other embodiments, when the electric control box 10 needs to be rotated, the box body can also not be disassembled, and the wire harness on the lower box body is reserved with sufficient length, which can meet the requirement of preventing the wire harness from falling off from the lower terminal during the rotation of the electric control box 10.
[0048] It can be understood that the strong current terminal group 29 and the weak current terminal group 30 are not limited to being arranged at the bottom of the electric control box 10, but can also be arranged at any position on the electric control box 10.
[0049] In some embodiments, as shown in Figure 6 As shown in the figure, the waterproof box 31 is fixed on the back of the electric control box 10, and the waterproof box 31 can be fixed on the relevant mounting structure by screws. The waterproof box 31 can isolate the key components (such as power supply modules, communication modules, etc.) on the back of the electric control box 10 from the external environment, achieve waterproof, dustproof, and corrosion resistance, and prolong the service life of the components. The electric control box 10 of the present application can be rotatably installed on the machine body, and when maintenance of the waterproof box 31 is needed, the electric control box 10 only needs to be rotated to a suitable angle to expose the waterproof box 31, thereby facilitating maintenance.
[0050] The present application also provides an air conditioner comprising the electric control box provided by the above embodiments and examples, which has all the beneficial effects mentioned in the above embodiments and examples, and details are not repeated here.
[0051] The electric control box and the air conditioner provided by the present application can rotatably set the electric control box 10 on the machine body of the air conditioner, and when the structure on the back of the electric control box 10 needs to be repaired or replaced, the electric control box 10 only needs to be rotated to a convenient angle for operation, without the need to completely disassemble the electric control box 10, or disassemble the related wire harness and refrigerant pipe, etc., which can greatly reduce the operation difficulty and improve the efficiency. Moreover, since the previous disassembly step is omitted, after the maintenance is completed, there is no need to perform the reinstallation step, which can avoid the wire harness connection error, ensure the normal operation of the machine. It can be understood that for the structure of the air conditioner arranged on the back side of the electric control box 10, when the electric control box 10 is rotated outward by a certain angle, it is also convenient for the staff to maintain the internal devices or structures, which provides operation convenience.
[0052] Further, by forming a communication path between the first refrigerant pipeline 11 and the second refrigerant pipeline, the refrigerant system on the air conditioner can be used to provide refrigerant for heat dissipation of the electric control box 10, so as to realize heat dissipation of the electric control box 10, without external refrigerant system, which is conducive to simplifying the structure configuration and reducing the cost. Since the first joint 12 protrudes downward relative to the bottom of the electric control box 10, even without rotating the electric control box 10, the connection or disconnection of the pipeline between the first joint 12 and the second joint 13 can be facilitated, especially under the premise that the electric control box 10 is rotatably arranged, after rotating the electric control box 10 for multiple times, the structure of the hose 14 may be affected, and the pipeline may be blocked or damaged, at this time, the hose 14 can be conveniently and quickly replaced, so as to ensure the heat dissipation effect of the refrigerant on the electric control box 10. In addition, the hose 14 with a preset shape is used to connect the first joint 12 and the second joint 13, which can take into account the rotation effect of the box and the use effect of the hose 14, that is, the hose 14 with a specific shape can ensure smooth rotation of the electric control box 10 and avoid rotation jamming, and at the same time, after the electric control box 10 is reset, the hose 14 can well recover the original shape, reducing the probability of local damage or deformation of the hose 14, so as to ensure the normal circulation of the refrigerant and the heat dissipation effect of the electric control box 10.
[0053] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
