DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work are within the protection scope of the present application.

[0027] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal", and "top, bottom" and the like indicate the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and in the absence of the opposite description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present application; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

[0028] For purposes of the description hereinafter, spatial relative terms, such as "above", "below", "upper", "lower", and the like, can be used to describe the relative position of one element or feature to another element or feature as illustrated in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "up" other elements or features would then be oriented "below" or "down" the other elements or features. Thus, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0029] In addition, it needs to be explained that the use of the words "first", "second" and the like to define parts, only for the convenience of distinguishing the corresponding parts, as no further declaration, the above words have no special meaning, therefore can not be understood as limiting the scope of protection of the utility model.

[0030] With reference to Figures 1 to 3 As shown in the figure, according to the embodiment of the utility model, an electric appliance box is provided, which comprises a box body 1 and a controller;The box body 1 comprises a main plate 11 and a cover plate 12, one side of the cover plate 12 is rotatably hinged with the main plate 11, and the cover plate 12 and the main plate 11 are combined to form the box body 1;The controller at least includes a first controller 21, a second controller 22 and a third controller 23, the first controller 21 is arranged on the inner wall of the main plate 11, and the second controller 22 and the third controller 23 are arranged on the outer wall of the main plate 11 and / or the outer wall of the cover plate 12 respectively.

[0031] Specifically, the first controller 21 is a drive plate, the second controller 22 is a main control plate, and the third controller 23 is a filter plate;When installing the first controller 21, first open the cover plate 12, install the first controller 21 on the inner wall of the main plate 11, and then cover the cover plate 12, so that the first controller 21 is located in the box body 1, and the second controller 22 and the third controller 23 are arranged on the outer wall of the box body 1.

[0032] In the embodiment, the first controller 21 is a drive board, which generates more heat than the other two controllers, so the first controller 21 is installed in a larger space, i.e., the inner wall of the main body plate 11, which can reduce the cumbersome steps in the assembly process and improve the assembly efficiency. The rotatable hinge of the cover plate 12 can facilitate opening and closing when the first controller 21 inside the box body 1 needs to be repaired and disassembled, and can also protect the internal drive board from dust, moisture and other environmental factors when it does not need to be opened. In order to avoid heat transfer between the controllers, the second controller 22 and the third controller 23 are arranged on the outer wall of the main body plate 11, and the main control board (second controller 22) and the filter board (third controller 23) are installed on the outer wall of the box body 1, which can use external air for natural heat dissipation, reduce internal heat accumulation, and improve the stability and reliability of the air conditioner. By installing different types of controllers in different positions of the appliance box, modular design can be achieved, which is convenient for later maintenance and upgrading. At the same time, since all the controllers are integrated in one appliance box, the assembly time on the general assembly line can be reduced, and the production cost of the appliance box can be reduced by optimizing the installation method of the controllers.

[0033] In combination with Figures 1 to 3 As shown in the figure, the first controller 21 is provided with a radiator 3, and the radiator 3 has a cooling water inlet pipe 301 for communicating with a water supply device.

[0034] Specifically, the first controller 21 generates relatively more heat, and the first controller 21 is provided with a radiator 3. The cooling water inlet pipe 301 of the radiator 3 communicates with an external water supply device. The cooling water inlet pipe 301 communicates with the copper pipe of the radiator 3. The water supply device sends water into the copper pipe of the radiator 3 through the cooling water inlet pipe 301. The water flows in the radiator 3 and transfers the heat generated by the first controller 21 to the water through heat conduction. The heat-exchanged water flows out of the radiator 3.

[0035] In the embodiment, compared with the conventional air cooling method of the radiator 3, water has a higher specific heat capacity, which means that the same mass of water can absorb more heat and rise less in temperature compared with other substances. The water cooling heat dissipation method can work in a wider range of environmental temperatures. Especially in high temperature environment, the water cooling heat dissipation method has better heat dissipation effect than the air cooling heat dissipation method, which can keep the controller running at a suitable temperature, improve the stability and reliability of the system. Therefore, using water as a cooling medium can more effectively absorb and remove the heat generated by the first controller 21. Through the flow of cooling water, the temperature of the controller can be maintained in a relatively stable state. When the controller generates too much heat, the cooling water can quickly absorb these heat and take away the heat through the circulation of water, preventing the controller from overheating, thereby protecting the electronic components and prolonging their service life.

[0036] As a specific embodiment, the heat sink 3 can be arranged at the position where the first controller 21 generates the most heat or the position where the components are arranged more densely. Using water cooling in the heat sink 3 can reduce the generation of local hot spots, i.e. the "hot island effect". Through the uniform distribution of water flow, heat can be more evenly conducted from the heat source to the entire heat sink 3, and then evenly dissipated to the environment, improving the overall heat dissipation efficiency. In addition, through effective heat dissipation, the water flow can also be intelligently adjusted by the temperature sensor and the controller, further enhancing the heat dissipation function and improving the energy efficiency.

[0037] As a specific embodiment, the second controller 22 and the third controller 23 are also provided with components for heat dissipation. Since the first controller 21 generates a large amount of heat, the first controller 21 is provided with a liquid-cooled heat sink 3.

[0038] Referring to Figures 1 to 3 As shown, the bottom side of the cover plate 12 is rotatably hinged to the main plate 11, and the two sides of the cover plate 12 are connected to the main plate 11 through the buckle structure 4.

[0039] Specifically, when the cover plate 12 needs to be opened, the cover plate 12 is outwardly opened relative to the main plate 11. When the cover plate 12 is closed, the cover plate 12 is retracted to the main plate 11, and the buckle structure 4 is connected to the main plate 11.

[0040] In this embodiment, the buckle structure 4 can firmly connect the cover plate 12 and the main plate 11 together when the cover plate 12 is closed, ensuring the stability of the appliance box during transportation or use, and preventing the cover plate 12 from accidentally falling off. Moreover, the buckle structure 4 can ensure the sealing between the cover plate 12 and the main plate 11, preventing environmental factors such as dust and moisture from entering the interior of the appliance box and protecting the internal controller module. Compared with traditional fixing methods such as screws, the buckle structure 4 simplifies the design of the appliance box, reduces the complexity and cost in the production process, and allows the cover plate 12 to be quickly disassembled and installed without the use of tools, improving the convenience of maintaining and inspecting the first controller 21.

[0041] Referring to Figures 1 to 3 As shown, the buckle structure 4 includes a buckle member, and the side wall of the main plate 11 is provided with a buckling part or a clamping groove 111, and the buckle member is connected to the buckling part or clamped to the clamping groove 111.

[0042] Specifically, when the side wall of the main plate 11 is provided with the buckling part, the buckle member is connected with the buckling part; when the side wall of the main plate is provided with the clamping groove 111, the buckle member is clamped with the clamping groove 111. In the embodiment, through the cooperation of the buckle member and the buckling part or the clamping groove 111, sufficient connection strength can be provided, so that the buckle structure 4 can be quickly assembled and disassembled without tools, and the efficiency of maintenance and repair is improved.

[0043] For reference Figures 1 to 3 As shown in FIG. 4, the buckle member is clamped with the clamping groove 111, and the buckle member includes a connecting piece 411 and a clamping hook 412. The connecting piece 411 is arranged on the cover plate 12, one end of the clamping hook 412 is connected with the connecting piece 411, and the other end of the clamping hook 412 faces the main plate 11. The side wall of the main plate 11 is provided with a turned-in flange 112, and the clamping groove 111 is arranged on the flange 112. The clamping hook 412 is clamped with the clamping groove 111.

[0044] Specifically, the connecting piece 411 is arranged on the cover plate 12, and the clamping hook 412 faces the main plate, that is, the clamping hook 412 is perpendicular to the flange 112. The clamping groove 111 is arranged on the flange 112. When the cover plate 12 needs to be connected with the main plate 11, the clamping hook 412 is rotated to one side of the main plate 11. Since the clamping hook 412 faces the clamping groove 111, the clamping hook 412 is clamped with the clamping groove 111, so that the cover plate 12 is connected with the main plate 11. When the box body 1 needs to be opened, the cover plate 12 is rotated in the opposite direction, and the clamping hook 412 is no longer connected with the clamping groove 111. The arrangement of the clamping hook 412 makes the opening and closing operation of the cover plate 12 simple. The cover plate 12 can be opened by rotating it outward, and the cover plate 12 can be closed by rotating it inward through the cooperation of the clamping hook 412 and the clamping groove 111.

[0045] In the embodiment, the main plate 11 is provided with the flange 112, the clamping groove 111 is arranged on the flange 112, and the clamping hook 412 is also connected through the connecting piece 411. This makes the entire structure more concealed and does not affect the appearance of the electric appliance box, maintaining the overall aesthetic appearance of the electric appliance box. The cooperation of the clamping hook 412 and the clamping groove 111 can achieve firm connection, so that the cover plate 12 is not easy to fall off when connected with the main plate 11, ensuring the sealing and integrity of the electric appliance box. In addition, the flange 112 structure can provide better support and clamping force due to its three-dimensional shape, so that the cooperation of the clamping groove 111 and the clamping hook 412 is more firm, thereby improving the stability and reliability of the entire connection structure. The flange 112 provides a clear assembly boundary, so that the position of the clamping groove 111 is more accurate, facilitating alignment during assembly, reducing assembly errors, improving assembly precision, and the flange 112 structure can also increase the rigidity of the connection area, reduce deformation caused by external force, and improve the stability of the entire structure.

[0046] For reference Figure 4 and Figure 5As shown, the buckle structure 4 further includes a tab 402, the side wall of the main plate 11 is provided with a first insertion hole 113, the side wall of the cover plate 12 is provided with a second insertion hole 121, and a cavity is formed between the side wall of the main plate 11 and the side wall of the cover plate 12; the clasp 412 includes a hook segment 413, the hook segment 413 penetrates the card slot 111 and extends into the cavity, and the tab 402 penetrates the cavity and abuts against the hook segment 413, and the two ends of the tab 402 are respectively inserted into the first insertion hole 113 and the second insertion hole 121.

[0047] Specifically, after the buckle penetrates the card slot 111, since the buckle is provided with the hook segment 413, the hook segment 413 has a certain length, the hook segment 413 extends into the cavity, and the tail of the hook segment 413 is upwardly bent. After the insertion end of the tab 402 is inserted from the first insertion hole 113, the tail of the hook segment 413 hooks the tab 402 after the tab 402 penetrates the cavity, the insertion end of the tab 402 is inserted into the second insertion hole 121, and the other end of the tab 402 is inserted into the first insertion hole 113; when the cover plate 12 needs to be opened, the tab 402 is first taken out of the insertion hole, so that the hook segment 413 can extend out of the card slot 111, and the cover plate 12 continues to rotate.

[0048] In this embodiment, the tab 402 penetrates the cavity and abuts against the hook segment 413, and the two ends are respectively inserted into the first insertion hole 113 and the second insertion hole 121. Such a design can ensure that the connection between the cover plate 12 and the main plate 11 is more stable, prevent accidental falling caused by external force, and provide an additional locking mechanism through the cooperation of the tab 402 and the card slot 111, so that the connection not only depends on the connection of the clasp 412 and the card slot 111, but also increases the stability of the insertion, thereby improving the reliability of the overall connection. Moreover, the addition of the tab 402 is equivalent to adding an additional connection point to the original buckle structure 4, which can improve the connection strength to a certain extent, especially when a larger external force is applied, the tab 402 can provide additional support. When the cover plate 12 needs to be opened, the tab 402 is only taken out of the insertion hole, so that the hook segment 413 can extend out of the card slot 111, and the cover plate 12 can be easily opened, simplifying the disassembly process and improving the disassembly efficiency. Moreover, the use of the tab 402 can provide additional safety protection when the clasp 412 fails unexpectedly, reducing the potential risks caused by connection failure. For example, when using a bolt connection, there is a risk of thread slipping during repeated disassembly. In other embodiments, the tab 402 can be adjusted according to actual needs, such as the length, width and shape of the tab 402, to adapt to different design requirements and use scenarios, providing greater flexibility.

[0049] For reference Figures 1 to 3As shown, the main plate 11 comprises a hinge frame 114 and sequentially connected first side plate 115, second side plate 116 and third side plate 117, the first side plate 115 is opposite to the third side plate 117, and the second side plate is opposite to the cover plate 12, one end of the hinge frame 114 is connected with the first side plate 115, the other end of the hinge frame 114 is connected with the third side plate 117, and the bottom side of the cover plate 12 is connected with the hinge frame 114 through the hinge 118.

[0050] In the embodiment, the side walls of the third side plate 117 and the first side plate 115 are respectively provided with the flanges 112, and the flanges 112 are respectively provided with the clamping grooves 111, and the outer wall of the third side plate 117 is further provided with the inductor 7, and through the hinge frame 114 and sequentially connected first side plate 115, second side plate 116 and third side plate 117, a stable frame structure is formed, which can effectively support and protect the components inside the electrical box, and the bottom side of the cover plate 12 is connected with the hinge frame 114 through the hinge 118, so that the cover plate 12 can rotate relative to the main plate 11, facilitating the user to open and close the cover plate 12, and the internal components are maintained or checked, and through the connection of the side plate and the hinge frame 114, the structural strength and rigidity of the whole main plate 11 are enhanced, so that it can withstand greater external force and reduce deformation.

[0051] As a specific implementation, the first side plate 115 and the third side plate 117 are provided with a wire passing plate 119, the wire passing plate 119 is provided with a branch line binding mounting hole and a backwater groove, which is used for wiring and waterproofing of the components of the electrical box.

[0052] For reference Figures 1 to 3 As shown, the first controller 21 is arranged on the inner wall of the second side plate 116, the second controller 22 is arranged on the outer wall of the cover plate 12, and the third controller 23 is arranged on the outer wall of the third side plate 117.

[0053] Specifically, the first controller 21 (drive plate) and the second controller 22 (main control plate) are arranged opposite to each other, the second controller 22 is provided with the wiring plate 8, and the third controller 23 is arranged on the side plate adjacent to the first controller 21, instead of the outer wall of the second side plate 116, and the embodiment limits the arrangement positions of the second controller 22 and the third controller 23, but as long as the two controllers are not arranged on the outer wall of the second side plate 116, the heat generated by the drive plate and the heat generated by the main control plate or the filter plate can be avoided from gathering together, and the drive plate is more difficult to be cooled.

[0054] In the embodiment, by separating the drive board with relatively serious heat generation from the main control board or the filter board, heat aggregation is avoided, heat dissipation of each board is facilitated, heat interference is reduced, system stability and reliability are improved, the layout mode can more effectively utilize the space of the electrical box, especially in a space-limited application scenario, the volume of the electrical box can be reduced, installation space is saved, and when a single controller needs to be maintained or upgraded, the single controller can be directly operated without disassembling other controllers, thereby improving maintenance convenience.

[0055] Referring to Figure 3 and Figure 6 , an air conditioner includes an electrical box, and the electrical box is an upper electrical box.

[0056] In the embodiment, by optimizing the layout of the controllers, the drive board (the first controller 21) with large heat generation is arranged on the inner wall of the second side plate 116, the main control board (the second controller 22) is arranged on the outer wall of the cover plate 12, and the filter board (the third controller 23) is arranged on the outer wall of the third side plate 117, so that heat can be effectively dispersed and aggregation of heat is avoided, thereby improving heat dissipation efficiency, the structural design of the electrical box can fully utilize the limited space of the air conditioner outdoor unit, the volume of the electrical box can be reduced without sacrificing performance on the premise of reasonable layout, more space is left for other components, the structural design of the electrical box takes into account the use of the air conditioner outdoor unit under various environmental conditions, the reasonable side plate and the hinged frame 114 design can improve the structural strength of the electrical box, so that the electrical box is more durable and reliable, the electrical box is arranged to allow quick disassembly and installation, maintenance work becomes easier and faster, maintenance efficiency is improved, maintenance time and cost are reduced, assembly process is simplified, and the time and labor required for assembly are reduced, thereby improving overall production efficiency.

[0058] Specifically, the heat exchanger 5 is a double-pipe heat exchanger 5, the double-pipe heat exchanger 5 itself needs to be connected to cold water, the water inlet pipe of the double-pipe heat exchanger 5 is provided with a branch pipe 501, cold water flowing into the branch pipe 501 flows into the copper pipe of the radiator 3, so that the radiator 3 can exchange heat with the heat dissipated by the controller, the water after heat exchange flows out from the cooling water outflow pipe 302 and flows into the flash evaporator 6 below, and is evaporated in the flash evaporator 6, so as to realize circulation of the entire water circuit.

The embodiment makes full use of the cold energy of the cooling water itself circulating belt, and exchanges the heat with the heat emitted by the controller through liquid cooling, which can more effectively conduct heat, help to improve the heat exchange efficiency, and accelerate the heat transfer process. By improving the heat exchange efficiency, the energy consumption is reduced, which helps to reduce the operation cost of the air conditioning system.
