[0023] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0024] In the first aspect, the embodiment of the application provides a grounding module for electric control box 100, and the electric control box 100 has an outer wall 101 and a grounding end (not shown in the figure) for grounding, as shown in the figure, the grounding module mainly includes an insulating support seat 10, a connecting hole 20, a grounding plate 30 and a conductive fastener 40. Figures 1 to 3

[0025] As shown in the figure, the electric control box 100 is used for the control of window type air conditioner, and the outer wall 101 is the outer wall of the electric control box 100. Figure 1 ​As shown, the insulating support seat 10 is arranged on the outer wall 101 of the electric control box 100, which is made of insulating material, such as plastic, to ensure the electrical safety of the grounding module. A connecting hole 20, which is a threaded hole in this embodiment, is formed in the insulating support seat 10 to cooperate with the conductive fastener 40. In a specific implementation, the grounding end of the electric control box 100 is also arranged in or communicated with the connecting hole 20 to facilitate the grounding connection of the conductive fastener 40.

[0026] The grounding plate 30 is detachably mounted on the insulating support seat 10 and suspended relative to the outer wall 101 of the electric control box 100. The grounding plate 30 can be made of metal material and detachably mounted on the insulating support seat 10 by clamping or other means, and is kept at a distance from the outer wall 101 of the electric control box 100 to form a suspended structure. This suspended structure not only avoids direct contact between the grounding plate 30 and the electric control box body, reducing the risk of corrosion and short circuit, but also effectively isolates the internal and external environments of the electric control box, improving the sealing performance of the electric control box. In some embodiments, as shown in Figure 3 The grounding plate 30 can also be provided with a plurality of grounding terminals and / or wiring holes 34 to connect other grounding wires, thereby forming a more complete grounding system.

[0027] The conductive fastener 40 is connected to the connecting hole 20 of the insulating support seat 10 at one end and electrically connected to the grounding end of the electric control box 100 to fix the grounding plate 30 on the insulating support seat 10. In this embodiment, the conductive fastener 40 is preferably a screw that cooperates with the threaded hole. The threaded end of the screw is accurately fitted with the threaded hole 20 of the insulating support seat 10, and the other end is reliably connected to the grounding end of the electric control box 100, ensuring the stability and reliability of the grounding connection.

[0028] In summary, the grounding module externally and suspends the grounding plate 30 by the insulating support seat 10, which not only effectively avoids direct contact between the grounding plate 30 and the electric control box body, improves the sealing performance of the electric control box, and significantly reduces the safety hazards caused by corrosion or short circuit of the grounding plate 30; and the suspended arrangement of the grounding plate 30 also reduces the risk of affecting the electric control box and even the internal circuit due to corrosion or damage of the fixing member, even if corrosion occurs, it will not directly affect the electric control box body; at the same time, the detachable mounting method also facilitates subsequent maintenance and replacement.

[0029] In some embodiments, the insulating support base 10 comprises a bayonet structure (not shown in the figure), and the grounding plate 30 is detachably clamped to the insulating support base 10 through the bayonet structure, and the bayonet structure is used for pre-positioning the grounding plate 30 before the conductive fastener 40 is connected. In the assembly process, the grounding plate 30 is first clamped by the bayonet structure to keep the grounding plate 30 in a relatively fixed pre-positioning state on the insulating support base 10, at this time, the assembler can operate the conductive fastener 40 such as a screw with both hands, and when the conductive fastener 40 is tightened, the fixation of the grounding plate 30 and the insulating support base 10 is further strengthened and the grounding is completed.

[0030] In a specific implementation, as shown in Figure 1 、 Figure 2 、 Figure 3 , the insulating support base 10 comprises a stud 11 and a support plate 12 arranged on both sides of the stud 11, and the connecting hole 20 is arranged on the stud 11; the two support plates 12 are respectively provided with a tenon 13 on the side facing away from each other; and the two short sides of the grounding plate 30 are bent to form a first side 31, and the first side 31 is provided with a mortise 32 corresponding to the position of the tenon 13, and the mortise 32 is clamped with the tenon 13 of the support plate 12.

[0031] Specifically, the two support plates 12 are spaced apart from the stud 11 to provide sufficient space for the suspension of the grounding plate 30, and during installation, only the mortise 32 on the first side 31 of the grounding plate 30 needs to be aligned with the tenon 13 on the support plate 12 of the support base 10, and the mortise 32 can be clamped with the tenon 13 by gently pressing, so that the grounding plate 30 is firmly installed on the support base 10, and then the grounding plate 30 is further fixed by the conductive fastener 40 to form a stable grounding structure.

[0032] In some embodiments, as shown in Figure 2 、 Figure 3 , at least one long side of the grounding plate 30 is bent to form a second side 33, and the second side 33 abuts against the support plate 12. Bending the long side of the grounding plate 30 to form the second side 33 can significantly increase the strength and rigidity of the grounding plate 30 itself. This makes the grounding plate 30 not easy to deform when subjected to external pressure or vibration, improves the stability of the structure, and the second side 33 abuts against the support plate 12 to form an additional support point, which helps to ensure that the grounding plate 30 can be more accurately positioned during installation, and can limit the rotation and inclination of the grounding plate 30 to ensure that the contact surface of the grounding plate 30 with the support base 10 remains in good condition.

[0033] In some embodiments, the stud 11 and the brace plate 12 are integrally formed with the outer wall 101 of the control box 100. The integrally formed design directly combines the stud 11 and the brace plate 12 with the outer wall 101 of the control box 100 without the need for separate parts and fasteners, thereby reducing the number of parts. This not only simplifies the structure, but also reduces production costs and assembly complexity.

[0034] In a second aspect, the embodiments provide a window air conditioner comprising the grounding module for an electric control box according to any one of the first aspect. It can be clearly understood by those skilled in the art that, for the convenience and brevity of description, the specific working process of the window air conditioner can refer to the corresponding process in the foregoing embodiments of the grounding module for an electric control box, and will not be described here.

[0035] The grounding module for an electric control box and the window air conditioner provided by the embodiments can form a suspended structure with the outer wall of the electric control box by using the insulating support seat, which can significantly save the internal space of the electric control box, avoid the limitation of the grounding module and its fixing parts on the internal element layout in the traditional scheme, and thus be conducive to the miniaturization and integration design of the electric control box. At the same time, since the grounding plate does not directly penetrate the outer wall of the electric control box, but is fixed only by the insulating support seat, the number of openings on the box body is greatly reduced, the sealing performance of the electric control box is effectively improved, the risk of invasion of water vapor, dust and the like is reduced, the reliability and service life of the internal electrical elements are improved, and the grounding module is particularly suitable for application environments such as window air conditioners which have high sealing requirements. In addition, the suspended arrangement of the grounding plate also reduces the risk of affecting the electric control box and even the internal circuit due to corrosion or damage of the fixing part. Even if corrosion occurs, it will not directly affect the electric control box body, thereby improving the safety and durability of the product. Furthermore, the external mounting manner makes the grounding module more convenient to assemble and maintain, and the operation can be performed without opening the electric control box, thereby reducing the maintenance difficulty and potential damage risk, having a longer service life and more convenient maintenance.
