Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Regarding the setting of the electronic control components in the heat pump unit, the previous practice was to integrate all the electronic control components on a large circuit board. When a certain electronic control component or circuit board fails and needs to be repaired, all related wiring harnesses must be removed for repair. The whole process is complicated and takes a long time to repair, which affects the working efficiency of the heat pump unit. In addition, a high level of after-sales repair skills is required for repair. When reinstalling after repair or replacement, the reinstallation speed is slow and it is easy to cause misconnection. In addition, a box cover is set to seal the large circuit board with integrated electronic control components. The size of the box cover must match the large circuit board. The installation of a large-sized box cover in the heat pump unit will inevitably cause inconvenience or even difficulty in installation.

[0042] Based on this, the utility model provides an electrical box, which integrates electrical control components that realize the same function on a circuit board to realize modularization, and then independently fixes a plurality of modular electrical control components on a side of the main box panel facing the inside of the main box body, and each modular electrical control component is then connected to the controlled device through a plug-in terminal block arranged on the panel. When an electrical control component fails, it is only necessary to unplug the connection line of the controlled device, and open or remove the panel corresponding to the electrical control component for repair or replacement. The maintenance is convenient, simple and fast, and the reinstallation after repair is quick and not easy to cause misconnection. At the same time, in the assembled state, the electrical control components of each module and the wires therebetween are all facing and integrated in the space inside the main box body, making the entire electrical box more compact and exquisite, saving space, more flexible to install, and avoiding line confusion.

[0043] See also Figure 1 , Figure 2 and Figure 4 An embodiment of the present application provides an electrical appliance box, including a main box body 10 and a plurality of electronic control components 20.

[0044] Specifically, in this embodiment, the plurality of panels are all square panels, including a first panel 11, a second panel 12, a third panel 13, a fourth panel 14, a fifth panel 15 and a sixth panel 16. Two adjacent panels are connected to each other through edges close to each other to form a hexahedron, and the accommodating cavity is located inside the hexahedron.

[0045] It is understandable that the main box body 10 is not limited to six panels, and can be a polyhedral main box body 10 formed by connecting eight, nine, ten or other numbers of panels, and is not limited thereto.

[0046] In this embodiment, the first connection structure includes a plurality of hinges 30, and the adjacent panels are connected by the hinges 30.

At the same time, the two movable leaves of each hinge are respectively fixed at the edges of the two adjacent panels that are close to each other. The connection between the sixth panel 16 and the second panel 12 can be connected by a plurality of hinges 30. When installing the electric control component 20, the sixth panel 16 can be rotated to an angle suitable for the installation operation by rotating the hinge 30; the connection between the sixth panel 16 and the second panel 12 can also be fixed. Preferably, on the basis that the other panels can be rotated and unfolded, the sixth panel 16 and the second panel 12 are fixedly connected in an integrated manner to ensure that the electric control component 20 can be easily installed on the sixth panel 16, and the stability of the entire electrical box is enhanced.

[0048] See also Figure 3 In some embodiments, the second connection structure includes a card plate 17 and a card slot 17a respectively arranged on two adjacent panels and cooperating with each other. The card plate 17 is fixed to an edge of one of the panels, and the card slot 17a is arranged at the edge of the other panel adjacent to the card plate 17. The card plate 17 is clamped in the card slot 17a to achieve the connection of the two adjacent panels.

Similarly, the sixth panel 16 is provided opposite to the fifth panel 15, and the second connection structure is also provided at two edges adjacent to the first panel 11 and the third panel 13 on both sides of the sixth panel 16. It can be understood that the two adjacent panels can be one of which has a card plate 17, and the other has a card slot 17a. By means of this card connection method, the fixed connection between the panels can be quickly achieved without the need for screw fixation, which facilitates the disassembly and assembly of the electrical box and improves the efficiency of installation and maintenance.

[0050] Please also see Figure 5 and Figure 6 In another embodiment, the second connection structure includes a first protrusion 18 and a groove 18a respectively arranged on two adjacent panels and cooperating with each other, and the first protrusion 18 is clamped in the groove 18a. In this embodiment, the second connection structure is arranged at two edges adjacent to the first panel 11 of the fifth panel 15; at the same time, the second connection structure is also arranged at two edges adjacent to the third panel 13 of the fifth panel 15. Similarly, the sixth panel 16 is arranged opposite to the fifth panel 15, and the second connection structure is also arranged at two edges adjacent to the first panel 11 and the third panel 13 on both sides of the sixth panel 16. It can be understood that the two adjacent panels can be either one of the panels is provided with the first protrusion 18, and the other panel is provided with the groove 18a.

[0051] See also Figure 7 In another embodiment, the second connection structure includes a second protrusion 19 and a clamping member 191. The second protrusion 19 and the clamping member 191 are respectively fixed on the side of two adjacent panels facing outside the accommodating cavity. The clamping member 191 includes a fixed end and a clamping end. The fixed end is fixed on the panel, and the clamping end extends to the second protrusion 19. The clamping end is provided with a clamping hole 19a. When the main box body is assembled, the second protrusion 19 is buckled in the clamping hole 19a. Specifically, the second protrusion 19 is fixed on the side of the first panel 11 facing outside the accommodating cavity and protrudes from the first panel 11. The fixed end of the clamping member 191 is fixed on the side of the fourth panel 14 facing outside the accommodating cavity. The clamping end and the fixed end are bent and the clamping end is bent toward the second protrusion 19. In a further embodiment, a through hole is provided on the second protrusion 19, and a latch or other stopper is inserted into the through hole to prevent the clamping end from moving out of the second protrusion 19. By arranging the second connection structure on the side of the panel facing outside the accommodating cavity, it is possible to quickly achieve a fixed connection between the panels while ensuring that the panel connected by the second connection structure is still firmly connected to other panels when a force is applied to the side facing outside the accommodating cavity.

[0052] In other embodiments, the first connection structure and the second connection structure may also be any one of various movable connection structures such as a mortise and tenon connection structure, an embedded connection structure, a concave-convex connection structure, and an inserted connection structure.

[0053] It is understandable that the connection between adjacent sides of the first panel 11, the second panel 12, the third panel 13, the fourth panel 14, the fifth panel 15 and the sixth panel 16 can be any combination of the first connection structure and the second connection structure, and is not limited thereto.

[0054] See also Figure 2 , several electric control components 20 are respectively fixed to different panels and arranged on the side of the panel facing the accommodating cavity, and the electric control components 20 on different panels are electrically connected through wires. As an example, in this embodiment, five electric control components 20 are integrated according to their functions, namely a main control module 21, a drive module 22, a power filter module 23, a safety relay module 24 and an electric energy metering module 25.

[0055] It is understandable that, since the main box body 10 can be a polyhedron with any number of faces, the number of modules integrated into the electric control component 20 can be determined according to the number of faces of the main box body 10. At the same time, the specific arrangement of the electric control component is determined according to its wiring convenience, but is not limited thereto.

[0056] Furthermore, the electrical box also includes a plurality of plug-in terminal blocks 40, at least one of the panels is provided with a plurality of first openings 40a, and the plug-in terminal blocks 40 are fixedly arranged at the first openings 40a; the plug-in terminal blocks 40 include male terminals and female terminals, the male terminals are electrically connected to the electric control component 20, and the female terminals are electrically connected to the external controlled device, or the female terminals are electrically connected to the electric control component 20, and the male terminals are electrically connected to the external controlled device. In this embodiment, the female terminals face one side of the accommodating space and are electrically connected to the electric control component 20, and the male terminals face one side outside the accommodating space and are electrically connected to the external controlled device. The number of the plug-in terminal seats 40 is determined according to the number of the controlled devices. The multiple plug-in terminal seats 40 can be dispersedly arranged on different panels or concentrated on the same panel. In this embodiment, as a preferred embodiment, the multiple plug-in terminal seats 40 are all arranged on the first panel 11, so that the connection lines of the controlled devices can be electrically connected to the plug-in terminal seats 40 from the same direction, which is convenient for the setting of the entire heat pump unit circuit and more beautiful. More preferably, the size of the first opening 40a is consistent with the size of the cross section of the plug-in terminal seat 40, so that the plug-in terminal seat 40 can be more firmly clamped in the first opening 40a and the airtightness of the electrical box is ensured.

[0057] When an electric control component 20 fails, it is only necessary to unplug the connecting wire of the controlled component from the corresponding male terminal or the female terminal, and open or remove the corresponding panel of the electric control component 20 for repair. When reinstalling after repair, it is only necessary to snap the corresponding panel into its original position. The whole process is simple and fast, and will not cause the wires to be pulled out or connected incorrectly.

[0058] See also Figure 8Furthermore, the heat pump unit will vibrate during operation. In order to prevent the connection line of the controlled device from being loosened due to vibration or other external factors after being connected to the end of the plug-in terminal seat 40 facing outside the accommodating cavity, a wiring guide 41 is provided at the end of the plug-in terminal seat 40 facing outside the accommodating cavity, and the wiring guide line 41 protrudes from the panel where the plug-in terminal seat 40 is located. A guide channel 41a is provided in the wiring guide 41, and one end of the wiring guide 41 is fixedly connected to the end of the end of the plug-in terminal seat 40 facing outside the accommodating cavity, or fixedly connected to the panel where the plug-in terminal seat 40 is located. After being fixed, the connection line of the controlled device passes through the guide channel 41a from the end of the wiring guide 41 away from the plug-in terminal seat 40 and is connected to the male terminal or the female terminal. In this embodiment, it is connected to the female terminal. Preferably, the cross section of the guide channel 41a is consistent with the cross section of the end of the plug-in terminal seat 40 facing outside the accommodating cavity. In addition, since the same plug-in terminal block 40 may be provided with multiple wiring ports, the corresponding connecting wires of the controlled devices are correspondingly provided with multiple wiring heads. In order to be able to quickly and conveniently connect the multiple wiring heads of the connecting wires of the controlled devices to the multiple wiring ports of the plug-in terminal block 40, a plurality of guide grooves are also provided in the guide channel 41a, and the guide grooves serve to guide the wiring heads of the connecting wires of the controlled devices.

[0059] Furthermore, since the electric control component 20 generates a large amount of heat when it is working, in order to ensure the working stability of the electric control component 20 and extend the life of the electric control component 20, a plurality of heat sinks 50 are further provided on the main housing 10, and a plurality of second openings 50a are provided on the panel, and the heat sinks 50 pass through the second openings 50a and are arranged opposite to the electric control component 20. Specifically, in order to ensure the airtightness of the electrical box, the number of the heat sinks 50 and the second openings 50a are the same. In this embodiment, the second openings 50a are provided on the sixth panel 16, and the heat sink 50 is composed of a plurality of heat sinks. One end of the heat sink 50a passes through the second openings 50a and is opposite to the driving module 22, and the other end protrudes outside the accommodating cavity. The heat generated by the driving module 22 when working is transferred to the end of the heat sink 50 away from the accommodating cavity through the heat sink 50a, and then dissipated to the external environment, thereby achieving a good heat dissipation effect. Preferably, the heat sink 50a passes through the second opening 50a and is fixed at the second opening 50a, which facilitates the quick and stable installation of the heat sink 50a, while also ensuring the airtightness of the electrical box to prevent dust, insects and other debris from entering the electrical box.

[0060] In another embodiment, a heat dissipation hole opposite to the electric control component 20 is provided on the panel provided with the electric control component 20, and the heat generated by the electric control component 20 is dissipated to the outside of the accommodating cavity through the heat dissipation hole.

Preferably, there are multiple fixing members 60, so that the connection between the electrical box and the device to be fixed is more stable.

[0062] Furthermore, a handle 70 is provided on the side of the panel facing the outside of the accommodating cavity, so that the electrical box can be easily carried after being removed from the device during maintenance. The handle 70 can be provided on any panel. Since the handle 70 will generate an upward force when lifting the entire electrical box, in this embodiment, as a preference, the handle 70 is provided on the fourth panel 14, and the fourth panel 14 is connected to the first panel 11 by a second connection structure, and the second connection structure connection can ensure the stability of the connection between the fourth panel 14 and the first panel 11.
