[0048] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art will understand that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although the embodiments are introduced in combination with a multi-connected air conditioner, this is not intended to limit the protection scope of the present application. Those skilled in the art can apply the present application to other application scenarios without departing from the principles of the present application, as long as the electrical equipment has an electrical control box.Figures 1-7 A preferred embodiment of the electric control box of the present application is introduced. Those skilled in the art will understand that the following embodiments are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. On the premise that the electric control box at least includes a box body 1, a protective cover 2 and a cover plate 3, those skilled in the art can adjust the following settings so that the present application can be applied to more specific application scenarios. Among them, the first direction refers to the attached Figures 1-2 、5-7 The X direction is the positive and negative direction indicated by the arrow, and the second direction refers to the attached Figures 1-2 、5-7 The arrows in the Z direction indicate the positive and negative directions, and the third direction refers to the Figures 1-2 , the positive and negative directions indicated by the arrows in the Y direction in 5-7.

[0049] like Figures 1-2 As shown, the electric control box is an electric control box for a multi-split air conditioner, and the electric control box includes a box body 1 and a cover body (not shown in the figure). The box body 1 is composed of a rear panel 13, a left panel 14 and a right panel 15 arranged on both sides of the rear panel 13 in the first direction, and an upper panel 16 and a lower panel 17 arranged on both sides of the rear panel 13 in the second direction, forming a storage space with an open side, and the cover body is arranged on the open side of the box body 1. The first drive board 6, the second drive board 7, the main control board 8, the power terminal block 4, the communication terminal block 5 and the filter 9 are arranged on the rear panel 13 in the box body 1. Among them, the first drive board 6, the second drive board 7 and the main control board 8 are arranged in sequence along the first direction and are all close to the upper panel 16, and the power terminal block 4, the filter 9 and the communication terminal block 5 are arranged in sequence along the first direction and are all close to the lower panel 17. A first connector 61 is located near the power terminal block 4 on the first driver board 6, and a second connector 71 is located near the filter 9 on the second driver board 7. Both the first connector 61 and the second connector 71 are connected to the compressor in the multi-split air conditioner via compressor cables, thereby controlling the compressor. A third connector 81 is located near the second driver board 7 on the main control board 8, and a fourth connector 82 is located near the communication terminal block 5. The third connector 81 is connected to the solenoid valve in the multi-split air conditioner via a solenoid valve cable, and the fourth connector 82 is connected to the sensor in the multi-split air conditioner via a sensor cable. The power terminal block 4 is equipped with multiple first wiring terminals 41 that connect to the power supply, facilitating access to the power cable and ensuring stable current transmission to meet the power requirements of the multi-split air conditioner. The communication terminal block 5 is equipped with multiple second wiring terminals 51 that connect to the communication module in the multi-split air conditioner to ensure information exchange. Through the above-mentioned setting method, the electric control box can effectively control the multi-split air conditioner, drive the compressor, solenoid valve, sensor and other components to work together, and ensure the efficient and stable operation of the multi-split air conditioner.

[0050] It should be noted that, since the electric control box is designed for multi-split air conditioner, its internal components, such as the first drive board 6, the second drive board 7, the filter 9, and the main control board 8, are configured according to the needs of the multi-split air conditioner. Therefore, when the electric control box is applied to different scenarios, the internal components can be adjusted accordingly according to the specific application needs.

[0051] Next, referring to Figure 2 , the internal space of the box body 1 is divided into a strong current area 11 and a weak current area 12, which are arranged in sequence along the first direction. In the multi-split air conditioner, the power terminal block 4, the compressor, and the electromagnetic valve belong to strong current equipment, and the communication module and the sensor belong to weak current modules. Therefore, the rear panel 13 in the strong current area 11 is provided with the first drive board 6, the second drive board 7, the power terminal block 4, and part of the main control board 8, which includes the third connecting seat 81. The filter 9 is arranged in the strong current area 11, so that the components in the strong current area can be prevented from being disturbed. The rear panel 13 in the weak current area 12 is provided with the communication terminal block 5 and the remaining part of the main control board 8, which includes the fourth connecting seat 82. The above arrangement makes the layout of the entire electric control box more clear and orderly.

[0052] It should be noted that a partition plate can also be arranged in the box body 1 to separate the strong current area 11 and the weak current area 12 into independent areas, which not only ensures the stable operation of the strong current equipment, but also reduces the electromagnetic interference of the components connected to the strong current equipment on the components connected to the weak current equipment.

[0053] Next, referring to Figure 2 , the first wire hole 171 and the second wire hole 172 are formed in the lower panel 17. The first wire hole 171 is arranged on the lower panel 17 corresponding to the strong current area 11, and the second wire hole 172 is arranged on the lower panel 17 corresponding to the weak current area 12. The first wire hole 171 is provided for the power line to pass through, so that the first wiring terminal 41 and the power supply are connected, and the second wire hole 172 is provided for the communication line to pass through, so that the second wiring terminal 51 and the communication module are connected. By providing special wire holes for the power line and the communication line on the electric control box, the power line and the communication line are effectively isolated, the electromagnetic field generated by the power line is effectively prevented from interfering with the communication line, and the communication line can accurately transmit signals, so that the multi-split air conditioner can operate normally and stably.

[0054] Of course, the application is not fixed to the first wire hole 171 and the second wire hole 172, and those skilled in the art can adjust according to the specific application scene, as long as the first wire hole 171 and the second wire hole 172 can separate the power line and the communication line. For example, the first wire hole 171 can also be arranged on the left panel 14, the right panel 15 or the rear panel 13. And / or, the second wire hole 172 can be arranged on the left panel 14, the right panel 15 or the rear panel 13. It should be noted that the power line is a wire connecting the first terminal 41 and the power supply, and the communication line is a wire connecting the second terminal 51 and the power supply. In order to distinguish, the wire connecting the first terminal 41 is named as the power line, and the wire connecting the second terminal 51 is named as the communication line.

[0055] Next participate Figure 2 The third wire hole 173, the fourth wire hole 174, the fifth wire hole 175 and the sixth wire hole 176 are also arranged on the box body 1, and the four wire holes are arranged on the lower panel 17. Among them, the third wire hole 173 is used for the first compressor wire to pass through, realizing the connection between the first connecting seat 61 and the compressor. The fourth wire hole 174 is used for the second compressor wire to pass through, realizing the connection between the second connecting seat 71 and the compressor. The fifth wire hole 175 is used for the electromagnetic valve wire to pass through, used to connect the third connecting seat 81 and the electromagnetic valve. The sixth wire hole 176 is used for the sensor wire to pass through, used to connect the sensor and the fourth connecting seat 82. Among them, the third wire hole 173, the fourth wire hole 174, the fifth wire hole 175 and the sixth wire hole 176 are arranged on the lower panel 17. The third wire hole 173, the fourth wire hole 174 and the fifth wire hole 175 correspond to the strong current area 11, and the sixth wire hole 176 corresponds to the weak current area 12. The above arrangement makes the internal structure of the electric control box simple and clear, and each area and the line keep independent and do not interfere with each other, which not only greatly facilitates the subsequent maintenance work, but also provides convenience for future re-planning and optimization of the internal line layout of the electric control box.

[0056] Of course, the application is not fixed to the third wire hole 173, the fourth wire hole 174, the fifth wire hole 175 and the sixth wire hole 176, and those skilled in the art can adjust them according to the needs. For example, the third wire hole 173, the fourth wire hole 174, the fifth wire hole 175 and the sixth wire hole 176 can also be arranged on the upper panel 16, the left panel 14, the right panel 15 or the rear panel 13. It should be noted that the first compressor wire is the wire connecting the first connecting seat 61 and the compressor, the second compressor wire is the wire connecting the second connecting seat 71 and the compressor, the electromagnetic valve wire is the wire connecting the third connecting seat 81 and the electromagnetic valve, and the sensor wire is the wire connecting the fourth connecting seat 82 and the sensor. In order to distinguish, the wire connecting the first connecting seat 61 and the compressor is named the first compressor wire, the wire connecting the second connecting seat 71 and the compressor is named the second compressor wire, the wire connecting the third connecting seat 81 and the electromagnetic valve is named the electromagnetic valve wire, and the wire connecting the fourth connecting seat 82 and the sensor is named the sensor wire.

[0057] Next, referring to Figures 1-3 The control box further comprises a protective cover 2, and the protective cover 2 comprises a front side plate 22, an upper side plate 23, a lower side plate 24, a left side plate 25 and a right side plate 26. The front side plate 22 is provided with a crease 21 extending in the first direction, so that the front side plate 22 is divided into a first side plate 221 and a second side plate 222, so that the first side plate 221 and the second side plate 222 can rotate relative to the crease 21. The first side plate 221 is arranged away from the lower panel 17, and the second side plate 222 is arranged close to the lower panel 17. The first side plate 221 is provided with the left side plate 25 and the right side plate 26 on both sides in the first direction, and is provided with the upper side plate 23 on one side in the second direction and away from the second side plate 222. The second side plate 222 is provided with the lower side plate 24 on one side in the second direction and away from the first side plate 221. The protective cover 2 encloses a containing cavity with a cover opening through the upper side plate 23, the lower side plate 24, the left side plate 25, the right side plate 26 and the front side plate 22. The cover opening end of the protective cover 2 is away from the front side plate 22, so that the protective cover 2 cooperates with the box body 1 to enable the power terminal strip 4, the communication terminal strip 5, the filter 9, the first connecting seat 61, the second connecting seat 71 and the fourth connecting seat 82 to be arranged in the space enclosed by the protective cover 2 and the box body 1, thereby protecting the power terminal strip 4, the communication terminal strip 5, the filter 9, the first connecting seat 61, the second connecting seat 71 and the fourth connecting seat 82 from external interference.

[0058] Of course, the number and form of the folds 21 are not fixed in the present application, and those skilled in the art can adjust them according to specific application scenarios. For example, the number of folds 21 can also be two, three or other numbers. And / or, the folds 21 can also extend along the second direction, so that the first side plate 221 and the second side plate 222 are sequentially arranged along the first direction. Among them, when the number of folds 21 is two and the folds 21 extend along the first direction, the front side plate 22 includes three side plates, which are sequentially arranged along the second direction, and the adjacent two side plates can rotate relative to the fold 21 between them. In addition, in other preferred embodiments, the folds 21 are not necessarily arranged, and those skilled in the art can select them according to needs. In the case where the folds 21 are not arranged, the left side plate 25 and the right side plate 26 are arranged on the two sides of the front side plate 22 in the first direction, and the upper side plate 23 and the lower side plate 24 are arranged on the two sides of the front side plate 22 in the second direction.

[0059] In addition, the corresponding rotating mode of the first side plate 221 and the second side plate 222 is not fixed in the present application, and those skilled in the art can adjust it according to needs. For example, the first side plate 221 and the second side plate 222 can be rotatably connected through a rotating shaft. In addition, the present application does not limit the components covered by the protective cover 2, as long as the protective cover 2 can cover the communication terminal row 5 and the power terminal row 4. For example, the protective cover 2 can only cover the communication terminal row 5 and the power terminal row 4, and not cover the first, second, fourth connecting seats. Or, the protective cover 2 can cover the communication terminal row 5, the power terminal row 4 and the first, second, third and fourth connecting seats.

[0060] Next, referring to Figures 3-5The upper side plate 23 is provided with a first handle 232 and a plurality of heat dissipation holes 231. The first handle 232 facilitates the disassembly of the protective cover 2. The heat dissipation holes 231 can effectively provide a heat dissipation channel for the internal components covered by the protective cover 2, such as the filter 9, to ensure that the electric control box maintains stable performance during long-time operation. The outer walls of the upper side plate 23, the lower side plate 24, the left side plate 25, and the right side plate 26 are each provided with a first clamping structure, which is a first buckle 27. The left panel 14, the right panel 15, the lower panel 17, and the rear panel 13 of the box body 1 are each provided with a second clamping structure that clamps and cooperates with the first clamping structure, which is a first clamping groove 151. Specifically, the right panel 15 is provided with a first clamping groove 151 that clamps and cooperates with the first buckle 27 on the right side plate 26. The edge of the left panel 14 is provided with a left outer edge, and the left outer edge and the space inside the box body 1 form a first clamping groove 151 that allows the first buckle 27 on the left side plate 25 to be clamped therein. Because the right panel 15 is provided with a first slot, the first buckle 27 on the left side plate 25 can abut against the left outer edge. The edge of the lower panel 17 is provided with a lower outer edge, and the lower outer edge and the space inside the box body 1 form a first clamping groove 151 that allows the first buckle 27 on the lower side plate 24 to be clamped therein and abut against the lower outer edge. The rear panel 13 is provided with a limiting block 131, and the limiting block 131 and the space inside the box body 1 form a first clamping groove 151 that allows the first buckle 27 on the upper side plate 23 to be clamped therein and abut against the limiting block 131. Through the above arrangement, the protective cover 2 can be connected to the box body 1, and the above arrangement facilitates the disassembly of the protective cover 2.

[0061] During the installation of the protective cover 2, the first buckle 27 on the lower side plate 24 is first aligned with the lower outer edge, so that the first buckle 27 is clamped into the area formed by the lower outer edge and the box body 1 and abuts against the lower outer edge. In this process, the second side plate 222 is also installed on the box body 1, and then the first side plate 221 is rotated clockwise, so that the first buckle 27 on the right side plate 26 is clamped into the first clamping groove 151 on the right panel 15, the first buckle 27 on the left side plate 25 is clamped into the area formed by the left outer edge and the box body 1 and abuts against the left outer edge, and the first buckle 27 on the upper side plate 23 is clamped into the area formed by the limiting block 131 and the box body 1 and abuts against the limiting block 131, thereby achieving the installation of the protective cover 2. During the disassembly of the protective cover 2, by applying a counterclockwise force to the first handle 232, the first buckle 27 on the front side plate 22, the left side plate 25, and the right side plate 26 are all disengaged from the corresponding first clamping groove 151 during the counterclockwise rotation of the first side plate 221 relative to the crease 21. Then, by applying a force, the lower side plate 24 is pulled out of the area formed by the lower panel 17 and the box body 1, thereby completing the disassembly of the protective cover 2.

[0062] Of course, the form of the first clamping groove 151 on the box body 1 and the setting position of the first handle 232 are not fixed, and those skilled in the art can adjust them according to needs. For example, the first clamping groove 151 can be directly formed on the left panel 14, the lower panel 17 and the rear panel 13 of the box body 1, without the need of forming the first clamping groove 151 by the outer edge or the limiting block 131 and the box body 1. Moreover, the first handle 232 can also be arranged on the first side plate 221, or the first handle 232 can be arranged on the second side plate 222 and the upper side plate 23 at the same time.

[0063] In addition, the specific setting form of the first clamping structure and the second clamping structure is not fixed, and those skilled in the art can adjust them according to needs. For example, the first clamping structure is the first clamping groove, and the second clamping structure is the first clamping buckle; or the first clamping structure is the first clamping hole, and the second clamping structure is the first clamping buckle; or the first clamping structure is the first clamping buckle, and the second clamping structure is the first clamping hole. Taking the first clamping structure as the first clamping hole and the second clamping structure as the first clamping buckle as an example, the first clamping hole is arranged on the upper side plate 23, the lower side plate 24, the left side plate 25 and the right side plate 26, and the first clamping buckle is arranged on the left panel 14, the right panel 15, the lower panel 17 and the rear panel 13.

[0064] Next, referring to Figure 2 and 6 , the first connecting hole 241, the second connecting hole 242 and the third connecting hole 243 are arranged on the lower side plate 24. The first connecting hole 241 and the second connecting hole 242 are located in the strong current area 11, and the first connecting hole 241 corresponds to and communicates with the first wire passing hole 171 on the box body 1, thereby facilitating the connection of the power supply wire and the first connecting terminal 41. The second connecting hole 242 corresponds to and communicates with the third wire passing hole 173, the fourth wire passing hole 174 and the fifth wire passing hole 175 on the box body 1, thereby facilitating the connection of the first compressor wire and the first connecting seat 61, the connection of the second compressor wire and the second connecting seat 71, and the connection of the electromagnetic valve wire and the third connecting seat 81. The third connecting hole 243 corresponds to and communicates with the second wire passing hole 172 and the sixth wire passing hole 176, thereby facilitating the connection of the communication wire and the second connecting terminal 51, and the connection of the sensor wire and the fourth connecting seat 82.

[0065] Of course, the number of connection holes on the protective cover 2 is not fixed in the present application, and those skilled in the art can adjust it according to the needs. For example, three second connection holes 242 can be provided on the lower side plate 24, which correspond to and communicate with the third wire passing hole 173, the fourth wire passing hole 174 and the fifth wire passing hole 175 respectively; and / or, two third connection holes 243 can be provided on the lower side plate 24, which correspond to and communicate with the second wire passing hole 172 and the sixth wire passing hole 176 respectively. Alternatively, one connection hole can be provided on the lower side plate 24, which corresponds to and communicates with the first, second, third, fourth, fifth and sixth wire passing holes respectively.

[0066] Next, referring to Figure 5 and 6 The first side plate 221 is provided with an observation window 2211 corresponding to the fourth connecting seat 82, which facilitates direct inspection of the fourth connecting seat 82 on the main control board 8 through the observation window 2211 to check whether there is improper condition such as missing insertion or wrong insertion, ensuring the stable operation of the sensor. The second side plate 222 is provided with a first wiring port 2221 and a second wiring port 2222, the first wiring port 2221 corresponding to the power terminal strip 4, facilitating the access of the power line and ensuring the stable supply of power. The second wiring port 2222 corresponds to the communication terminal strip 5, which is conducive to the connection of the communication cable and ensures the efficiency and accuracy of data transmission. Among them, the first wiring port 2221 penetrates the second side plate 222 near the left panel 14 and near the lower panel 17. The second wiring port 2222 penetrates the second side plate 222 near the right panel 15 and near the lower panel 17.

[0067] Of course, the specific form of the front side plate 22 is not fixed in the present application, and those skilled in the art can adjust it according to the needs. For example, the first side plate 221 can also be provided with observation windows 2211 corresponding to the first connecting seat 61 and the second connecting seat 71 respectively. It should be noted that in other preferred embodiments, the observation window 2211 on the first side plate 221 is not necessarily provided, and those skilled in the art can choose according to the needs. In the case where the observation window 2211 is not provided, the first side plate 221 is removed from the box body 1 to observe whether there is improper condition such as missing insertion or wrong insertion of the fourth connecting seat 82 or other connecting seats.

[0068] In addition, the first and second wiring ports 2221 and 2222 are not fixed in the specific forms, and those skilled in the art can adjust them according to needs. The first wiring port 2221 only penetrates one side of the second side plate 222 close to the left panel 14 or only penetrates one side of the second side plate 222 close to the lower panel 17, or the first wiring port 2221 is a closed hole and does not penetrate one side of the second side plate 222 close to the left panel 14 and one side of the second side plate 222 close to the lower panel 17. And / or, the second wiring port 2222 only penetrates one side of the second side plate 222 close to the right panel 15 or only penetrates one side of the second side plate 222 close to the lower panel 17, or the second wiring port 2222 is a closed hole and does not penetrate one side of the second side plate 222 close to the right panel 15 and one side of the second side plate 222 close to the lower panel 17.

[0069] Next, referring to Figure 1 、 5 -7, the first and second wiring ports 2221 and 2222 are provided with cover plates 3, which are rotationally connected to the protective cover 2 through the creases 21, so that the cover plates 3 can be opened or closed to the corresponding wiring ports 2221. One side of the cover plate 3 on the first wiring port 2221 close to the left panel 14 and one side of the cover plate 3 on the second wiring port 2222 close to the right panel 15 are provided with support pieces, and the opposite sides of the two cover plates 3 are provided with fourth clamping structures, which are second clamping holes 31. The support piece includes a support rod 32 and a support block 321, wherein the support rod 32 extends in the direction of the rear panel 13 when the cover plate 3 is in the closed state, and the support block 321 is arranged on the outer side of the support rod 32, so that when the cover plate 3 is in the open state, the support block 321 can be supported on the box body 1, effectively preventing the cover plate 3 from falling back during wiring or disconnection operation. The inner walls of the first and second wiring ports 2221 and 2222 are provided with third clamping structures matched with the fourth clamping structures, which are second buckles 2221, so that the cover plates 3 are connected with the protective cover 2, realizing the closing of the wiring ports 2221.

[0070] Of course, the specific arrangement of the third and fourth clamping structures is not fixed, and those skilled in the art can adjust them according to needs. For example, the third clamping structure is a second buckle, and the fourth clamping structure is a second clamping groove; or the third clamping structure is a second clamping groove, and the fourth clamping structure is a second buckle; the third clamping structure is a second clamping hole 31, and the fourth clamping structure is a second buckle.

[0071] In addition, the application is not fixed to the way that the cover plate 3 is rotationally connected to the protective cover 2 and the specific setting form of the support. Those skilled in the art can adjust it according to the needs. For example, the cover plate 3 can be rotationally connected to the protective cover 2 through a rotating shaft. And / or, the support only includes a support rod 32, which is inclined along the cover plate 3 in the direction away from the side where the second clamping hole 31 is located, so that the support rod 32 can support on the box body 1 when the cover plate 3 is in the open state. It should be noted that when the wiring port 2221 is a closed port or the wiring port 2221 only penetrates the second side plate 222 near the side where the lower panel 17 is located, the support block 321 can support on the second side plate 222 when the cover plate 3 is opened, thereby preventing the cover plate 3 from falling back.

[0072] In other preferred embodiments, the support is not necessarily provided, and those skilled in the art can choose according to the needs. In the case where the support is not provided, in order to ensure that the cover plate 3 opens the wiring port 2221 and does not fall back by itself, the cover plate 3 can be supported by other supports independent of the electric control box.

[0073] Next, referring to Figures 5-7 , a second handle 33 is arranged on the outer wall of the cover plate 3, which facilitates the cover plate 3 to rotate around the crease 21 under the action of the second handle 33, so as to realize the opening or closing operation of the wiring port 2221. A text mark 34 is arranged on the same side of the cover plate 3 as the second handle 33, so that the staff can operate according to the text mark 34 on the cover plate 3. A limiting plate 2224 is arranged on the inner wall of the first wiring port 2221 away from the left panel 14 and the inner wall of the second wiring port 2222 away from the right panel 15, and the distance between the limiting plate 2224 and the rear panel 13 in the third direction is less than the distance between the second clamping buckle 2221 and the rear panel 13 in the third direction, so that when the second clamping hole 31 on the cover plate 3 is clamped with the second clamping buckle 2221 on the inner wall of the wiring port 2221, the cover plate 3 can abut against the limiting plate 2224, facilitating the cover plate 3 to close the corresponding wiring port 2221.

[0074] It should be noted that the application is not fixed to the setting position of the text mark 34, and those skilled in the art can adjust it according to the needs. For example, the text mark 34 can also be arranged on the first side plate 221 or the second side plate 222 near the wiring port 2221. In addition, the application does not limit the specific content of the text mark 34, as long as it can guide the staff to operate correctly. For example, the text mark 34 can be a strong and weak current mark, a warning mark, and / or information of a specific wiring terminal.

[0075] In addition, the application is not necessary to set the limiting plate 2224, and those skilled in the art can select as needed. In the case of not setting the limiting plate 2224, the cover plate 3 is clamped by the second clamping hole 31 on the second clamping buckle 2221 on the inner wall of the wiring port 2221.

[0076] In addition, the utility model provides an electrical equipment, and the electrical equipment includes the electric cabinet of any implementation in the above.

[0077] So far, the technical scheme of the application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the application, and the technical schemes after the changes or replacements will fall within the protection scope of the application.
