[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0024] This application provides an electrical control box to solve the problem of inconvenient disassembly of the electrical control box of a duct air conditioner. The following description will be provided in conjunction with the accompanying drawings.

[0025] In the embodiments of this application, such as Figure 1 As shown, the electrical control box includes a box body 1 and a wire clamping component 2. A control component 3 is provided inside the box body 1. The box body 1 is provided with an access port 11 that exposes the control component 3. The wire clamping component 2 is detachably connected to the box body 1 to clamp the external wiring of the electrical control box. At least a portion of the wire clamping component 2 is located in the access port 11 to prevent the control component 3 from coming out of the box body 1.

[0026] It should be noted that control component 3 refers to a circuit board with control functions, and in this embodiment, it mainly refers to the main control board. Inspection port 11 refers to an opening reserved in the housing 1 during the manufacturing process to facilitate maintenance of other components inside the housing 1. External wiring of the electrical control box refers to the wires connecting other functional modules in the duct air conditioner to the electrical control box to achieve control of those other functional modules.

[0027] It is understandable that by using the wire clamping component 2, while securing the external wiring, at least part of the wire clamping component 2 is designed at the inspection port 11 to prevent the electrical control box from coming out of the box body 1 through the inspection port 11. Especially for electrical control boxes that are disassembled in the vertical direction, the disassembly action can be completed with both hands without manually holding and securing the electrical control box, which is beneficial to improving the convenience of operation. Moreover, the structure is simple and easy to produce.

[0028] In some embodiments, such as Figure 2 As shown, the wire clamping component 2 includes a snap-fit ​​part 21, and the inner wall of the inspection port 11 is provided with a snap-fit ​​12. The snap-fit ​​part 21 snaps into the snap-fit ​​12 and extends into the inspection port 11 to prevent the control component 3 from coming out of the box body 1.

[0029] Understandably, when the snap-fit ​​part 21 completes the snap-fit ​​action with the bayonet 12, it simultaneously achieves the clamping and fixing of the external line and the part of the snap-fit ​​part 21 extends into the inspection port 11 through the bayonet 12. The installation process of the wire clamping part 2 is completed in one go, and the operation is simple and fast.

[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, a slide groove 13 is provided inside the box body 1, and the control component 3 is slidably connected in the slide groove 13 to slide into or out of the box body 1.

[0031] It should be noted that the control component 3 is slidably connected within the slide groove 13 to slide into or out of the housing 1, meaning that the extension direction of the slide groove 13 points towards the inspection port 11. This allows the control component 3 to be pushed in and pushed out while sliding along the slide groove 13. Furthermore, the slide groove 13 restricts the movement direction of the control component 3, preventing it from swaying freely within the housing 1. In addition, a rotatably connected roller can be installed on the inner wall of the slide groove 13, enabling a rolling connection between the roller and the control component 3, facilitating the pulling of the control component 3 out of the housing 1 or its return to the housing 1.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, each of the two opposite inner walls of the box 1 is provided with a slide groove 13, and the control component 3 is slidably connected in the two slide grooves 13.

[0033] In some embodiments, such as Figure 2 As shown, the snap-fit ​​part 21 opens toward one end of the slide groove 13 near the inspection port 11, and the snap-fit ​​part 21 is used to prevent the control member 3 from being dislodged from the slide groove 13.

[0034] It should be noted that the opening at the end of the slide groove 13 near the inspection port 11 refers to the opening where the control component 3 slides away from the slide groove 13.

[0035] Understandably, since the extension direction of the slide groove 13 restricts the movement direction of the control member 3, by having the locking part 21 engage with the latch 12 and the portion extending into the access port 11 located at one end of the slide groove 13 latch 12, the control member 3 is prevented from disengaging along the slide groove 13, thus preventing the control member 3 from exiting the housing 1 through the access port 11. This method offers higher reliability compared to directly designing the locking part 21 at any position in the access port 11. When there are two or more slide grooves 13, the locking part 21 only needs to open towards one end of one of the slide grooves 13.

[0036] In some embodiments, such as Figure 2 As shown, the wire pressing component 2 also includes a fastening part 23 and a wire pressing part 22 that are connected to each other. The box body 1 is provided with a fastening connection hole. After the fastener passes through the fastening part 23, it is fastened to the fastening connection hole. The wire pressing part 22 is spaced apart from the box body 1 to form a wire pressing groove. The snap-fit ​​part 21 is connected to the end of the wire pressing part 22 away from the fastening part 23.

[0037] It should be noted that fasteners can be screws, bolts, etc. Fastening holes refer to threaded holes.

[0038] It is understood that the wire clamping component 2 is detached and connected to the housing 1 through its fastening part 23 and its snap-fit ​​part 21. During installation, the fastener can be passed through the fastening part 23 and tightened a few turns to temporarily position the wire clamping component 2. Then, the snap-fit ​​part 21 is snapped into the bayonet 12 and the fastener is tightened to complete the installation of the wire clamping component 2. In this way, on the one hand, the pre-positioning of the fastening part 23 facilitates the snap-fit ​​of the snap-fit ​​part 21 to avoid interference between the snap-fit ​​part 21 and the side wall of the bayonet 12. On the other hand, the tightness of the fastener can be used to adjust the clamping force on the external wire. In some specific embodiments, the snap-fit ​​part 21 and the fastening part 23 are respectively connected to the two ends of the wire clamping part 22.

[0039] In some embodiments, such as Figure 2 As shown, the box body 1 has a notch 14, which penetrates the adjacent side wall of the box body 1 and the connection between the adjacent side walls. The notch 14 and the pressure piece 2 enclose each other to form a pressure groove.

[0040] Understandably, such a notch 14 facilitates the insertion of external lines and can also hide the external lines in the box 1, preventing the external lines and wire clamps 2 from protruding from the surface of the box 1.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the box body 1 is provided with a first card interface 15, which is located near the maintenance port 11; the electrical control box also includes a box cover 4 for covering the maintenance port 11, and the box cover 4 is provided with a hook 41 for inserting the first card interface 15.

[0042] It is understandable that after the hook 41 is inserted into the first card interface 15, the box cover 4 is pre-fixed by hooking onto the peripheral wall of the first card interface 15.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the box body 1 is provided with a buckle 16, which is located near the inspection port 11. The hook 41 and the buckle 16 are located on different sides of the electrical control box. The box cover 4 is provided with a second card interface 42, and the buckle 16 is engaged with the second card interface 42.

[0044] It should be noted that the buckle 16 achieves fixation by deforming itself to pass through the second card interface 42 and hooking onto the peripheral wall of the second card interface 42. In this application, the function of the hook 41 is to pre-position the cover 4 onto the box body 1, and the function of the buckle 16 is to fix the cover 4 onto the box body 1. It can be understood that by using the combination of the hook 41 and the buckle 16 to complete the installation of the cover 4, it is easier for the repair technician to ensure that the cover 4 has the correct installation posture during the installation process, which facilitates quick and one-time installation.

[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the second card interface 42 and the first card interface 15 are located on different sides of the control box. Along the direction in which the buckle 16 is inserted into the second card interface 42, the width of the first card interface 15 gradually decreases so that the card hook 41 is hooked onto the box cover 4.

[0046] Understandably, the second card interface 42 and the first card interface 15 are located on different sides of the control box, allowing different sides of the box body 1 to be fixed to the box cover 4 via hooks 41 and buckles 16. As the buckle 16 gradually approaches the second card interface 42, the gradually decreasing width of the first card interface 15 constrains the hook 41 along its width, preventing it from detaching. When the buckle 16 engages with the second card interface 42, the periphery of the first card interface 15 completely restricts the movement of the hook 41, thus securing the box cover 4. Similarly, in the opposite direction of the buckle 16 engaging with the second card interface 42, the width of the first card interface 15 gradually increases, facilitating the technician's insertion of the hook 41 into the first card interface 15 and enabling quick assembly and disassembly of the box body 1.

The specific structure of the electrical control box is as described in the above embodiments. Since this duct air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
