Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a grounding mechanism for an air conditioner and an air conditioner. Background Technology

[0002] The grounding wire of an air conditioner is a crucial component for ensuring safe operation of the equipment and protecting users from the risk of electric shock. The grounding wire of the indoor unit is typically fixed to the evaporator tube sheet using a grounding screw. The grounding wire is fitted onto the grounding screw via a grounding washer. When the grounding screw is tightened, friction causes the grounding washer and grounding wire to rotate together with the screw. This rotation pulls on the grounding wire, potentially leading to poor grounding or even breakage.

[0003] Therefore, how to solve the problem of poor grounding or even breakage of grounding wires caused by easy pulling during installation has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0004] This utility model provides a grounding mechanism and an air conditioner to solve the defects in related technologies where the grounding wire is easily pulled during installation, resulting in poor grounding or even breakage.

[0005] This utility model provides a grounding mechanism for an air conditioner, comprising:

[0006] Grounding hole, located on the evaporator tube sheet of the air conditioner;

[0007] A grounding pin is detachably connected to the grounding hole;

[0008] A grounding pad has a first connecting portion, a second connecting portion, and a transition portion. The first connecting portion is adapted to be sleeved on the outside of the grounding nail, the second connecting portion is adapted to connect to a grounding wire, and the transition portion is disposed between the first connecting portion and the second connecting portion. Both the first connecting portion and the second connecting portion are connected to the transition portion.

[0009] A limiting structure is disposed between the evaporator tube sheet and the transition portion, and the limiting structure is adapted to restrict the movement of the transition portion relative to the evaporator tube sheet.

[0010] With this configuration, when connecting the grounding nail to the grounding hole, the limiting structure can restrict the movement of the transition part relative to the evaporator tube sheet, thereby limiting the rotation of the grounding pad and the grounding wire, avoiding pulling on the grounding wire, and solving the problem in related technologies where the grounding wire is easily pulled during installation, resulting in poor grounding or even being pulled off.

[0011] In addition, the limiting structure acts on the transition part of the grounding pad, which can avoid restricting the shape of the first connecting part. The first connecting part can be, but is not limited to, a rectangle, a circle, a polygon, etc.

[0012] According to the grounding mechanism of an air conditioner provided by this utility model, the limiting structure includes:

[0013] The evaporator tube sheet has a limiting hole and a limiting protrusion, the limiting protrusion being adapted to be fitted into the limiting hole, one of the limiting hole and the limiting protrusion being disposed in the evaporator tube sheet, and the other being disposed in the transition portion.

[0014] With this configuration, the structure of the limiting protrusion and the limiting hole is simple. Through the interaction between the limiting hole and the limiting protrusion, the movement of the transition section relative to the evaporator tube sheet can be restricted.

[0015] According to the present invention, a grounding mechanism for an air conditioner is provided, wherein the limiting hole is provided on the evaporator tube plate, and the limiting protrusion is provided on the side of the transition portion facing the evaporator tube plate.

[0016] With this configuration, the grounding pad is smaller in size, and the limiting hole is placed on the evaporator tube sheet, avoiding the placement of holes in the transition part of the grounding pad, thus ensuring the structural strength of the grounding pad.

[0017] According to the grounding mechanism of an air conditioner provided by this utility model, each grounding hole is provided with at least two limiting holes, and each limiting hole is distributed at intervals along the length direction of the evaporator tube plate.

[0018] This design, with different distances between the limiting holes and grounding holes, accommodates the installation of grounding pads with varying distances between the limiting protrusions and connecting holes. Furthermore, the angles between the lines containing the different limiting holes and grounding holes and the length of the evaporator tube sheet are different. The connecting holes of the grounding pads correspond to the grounding holes, and by interacting the limiting protrusions on the grounding pads with the different limiting holes on the evaporator tube sheet, the varying angles between the length of the grounding pads and the length of the evaporator tube sheet allow for grounding wires with different wiring directions, enabling the grounding wires to bend naturally and avoiding excessive bending.

[0019] According to the grounding mechanism of an air conditioner provided by this utility model, each grounding hole is provided with at least two limiting holes, and each limiting hole is distributed circumferentially around the grounding hole.

[0020] With this configuration, the distance between different limiting holes and grounding holes is the same, and the angle between the straight line containing different limiting holes and grounding holes and the length direction of the evaporator tube sheet is different. The same grounding pad can be adapted to different limiting holes, and the same grounding pad can have different installation directions, adapting to different wiring directions and exhibiting strong adaptability.

[0021] According to the present invention, a grounding mechanism for an air conditioner is provided, wherein the limiting protrusion is disposed on one side edge of the transition portion, and the limiting protrusion is formed by bending.

[0022] This setup simplifies the processing technology, allows for mass production using molds, and reduces processing costs.

[0023] According to the present invention, an air conditioner grounding mechanism is provided, wherein at least two grounding holes are provided on the evaporator tube plate, and each grounding hole is spaced apart along the length direction of the evaporator tube plate, and each grounding hole is correspondingly provided with the limiting structure.

[0024] With this configuration, different air conditioner models require different numbers of grounding wires, which in turn affects the required number of grounding holes on the evaporator tube sheet. In this embodiment, multiple grounding holes are provided on the evaporator tube sheet. For models requiring fewer grounding wires, the appropriate number and location of grounding holes can be selected as needed. For models where the required number of grounding wires matches the number of grounding holes on the evaporator tube sheet, all grounding holes on the evaporator tube sheet can be used. In other words, the evaporator tube sheet is suitable for both models requiring fewer and more grounding wires, improving its versatility.

[0025] According to the grounding mechanism of an air conditioner provided by this utility model, the second connecting part includes:

[0026] The connecting body is connected to the transition part;

[0027] A clamping part is provided on the connecting part body, and the clamping part is adapted to clamp and fix the grounding wire to the connecting part body.

[0028] This design secures the grounding wire by clamping it with the clamping force of the clip section. It is simple in structure, easy to manufacture, and low in cost.

[0029] According to the grounding mechanism of an air conditioner provided by this utility model, the outline of the first connecting part is arc-shaped, and the edge of the first connecting part is smoothly connected to the edge of the transition part.

[0030] With this configuration, the outline of the first connection part matches the outline of the cap end of the grounding nail, which can improve the aesthetics of the air conditioner's grounding mechanism.

[0031] This utility model also provides an air conditioner, including the grounding mechanism of the air conditioner described above.

[0032] The grounding mechanism for an air conditioner provided by this utility model includes a grounding hole, a grounding nail, a grounding pad, and a limiting structure. The grounding hole is disposed on the evaporator tube plate of the air conditioner, and the grounding nail is detachably connected to the grounding hole. The grounding pad has a first connecting part, a second connecting part, and a transition part. The transition part is disposed between the first connecting part and the second connecting part, and both the first and second connecting parts are connected to the transition part. The first connecting part is used to be sleeved on the outside of the grounding nail, and the second connecting part is used to connect the grounding wire. When installing the grounding wire, the grounding wire is connected to the second connecting part of the grounding pad, then the first connecting part of the grounding pad is sleeved on the grounding nail, and then the grounding nail is connected to the grounding hole. The limiting structure is disposed between the evaporator tube plate and the transition part, and the limiting structure is used to restrict the movement of the transition part relative to the evaporator tube plate. With this configuration, when connecting the grounding nail to the grounding hole, the limiting structure can restrict the movement of the transition part relative to the evaporator tube sheet, thereby limiting the rotation of the grounding pad and the grounding wire, avoiding pulling on the grounding wire, and solving the problem in related technologies where the grounding wire is easily pulled during installation, resulting in poor grounding or even being pulled off.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined with Figures 1 to 5 This invention describes the grounding mechanism of the air conditioner.

[0044] like Figures 1 to 5 As shown, the grounding mechanism of the air conditioner provided in this embodiment of the present invention includes a grounding hole 1, a grounding nail 3, a grounding pad 4, and a limiting structure.

[0045] Specifically, grounding hole 1 is located on the evaporator tube plate 2 of the air conditioner, and grounding nail 3 is detachably connected to grounding hole 1.

[0046] Specifically, the grounding nail 3 can be a grounding screw, and the grounding hole 1 can be a threaded hole, so that the grounding nail 3 is threadedly connected to the grounding hole 1. When connecting the grounding nail 3 to the grounding hole 1, a torque is applied to the grounding nail 3 to make the grounding nail 3 rotate relative to the grounding hole 1. The operation is simple and convenient.

[0047] The grounding pad 4 has a first connecting portion 5, a second connecting portion, and a transition portion 7. The transition portion 7 is disposed between the first connecting portion 5 and the second connecting portion, and both the first connecting portion 5 and the second connecting portion are connected to the transition portion 7. The second connecting portion is used to connect the grounding wire 8. The first connecting portion 5 is used to be sleeved on the outside of the grounding nail 3. Specifically, a connecting hole 11 can be provided in the first connecting portion 5 for the grounding nail 3 to pass through.

[0048] When installing the grounding wire 8, connect the grounding wire 8 to the second connecting part of the grounding pad 4, then put the first connecting part 5 of the grounding pad 4 onto the grounding nail 3, and then connect the grounding nail 3 to the grounding hole 1.

[0049] A limiting structure is provided between the evaporator tube sheet 2 and the transition section 7. The limiting structure is used to restrict the movement of the transition section 7 relative to the evaporator tube sheet 2.

[0050] With this configuration, when the grounding nail 3 is connected to the grounding hole 1, the limiting structure can restrict the movement of the transition part 7 relative to the evaporator tube plate 2, thereby restricting the rotation of the grounding pad 4 and the grounding wire 8, avoiding pulling on the grounding wire 8, and solving the problem in related technologies where the grounding wire 8 is easily pulled during installation, resulting in poor grounding or even breakage of the grounding wire.

[0051] In addition, the limiting structure can replace manual restriction of the rotation of the grounding pad 4 and the grounding wire 8, reducing the installation difficulty of the grounding wire 8 and making it more ergonomic. The limiting structure acts on the transition part 7 of the grounding pad 4, which can avoid restricting the shape of the first connecting part 5. The first connecting part 5 can be, but is not limited to, a rectangle, a circle, a polygon, etc.

[0052] In this embodiment, the limiting structure includes a limiting hole 9 and a limiting protrusion 10, and the limiting protrusion 10 can be embedded in the limiting hole 9.

[0053] One of the limiting hole 9 and the limiting protrusion 10 is provided on the evaporator tube plate 2, and the other is provided on the transition section 7. Through the interaction between the limiting hole 9 and the limiting protrusion 10, the movement of the transition section 7 relative to the evaporator tube plate 2 can be restricted.

[0054] In some embodiments, the limiting protrusion 10 is provided on the evaporator tube sheet 2, and the limiting hole 9 is provided on the transition portion 7 of the grounding pad 4.

[0055] In other embodiments, the limiting hole 9 is provided on the evaporator tube plate 2, and the limiting protrusion 10 is provided on the side of the transition portion 7 facing the evaporator tube plate 2, as shown in the figure. Figure 5 The grounding pad 4 is relatively small in size. By setting the limiting hole 9 on the evaporator tube plate 2 and avoiding setting the hole in the transition part 7 of the grounding pad 4, the structural strength of the grounding pad 4 can be ensured.

[0056] In some embodiments of this utility model, limiting holes 9 are provided on the evaporator tube plate 2, and limiting protrusions 10 are provided on the transition portion 7. Each grounding hole 1 is provided with at least two limiting holes 9, and the limiting holes 9 are spaced apart along the length direction of the evaporator tube plate 2.

[0057] Different limiting holes 9 have different distances from grounding holes 1, which can accommodate the installation of grounding pads 4 with different distances between limiting protrusions 10 and connecting holes 11. Furthermore, the angles between the straight lines containing different limiting holes 9 and grounding holes 1 and the length direction of the evaporator tube sheet 2 are different. The connecting holes 11 of the grounding pad 4 correspond to the positions of the grounding holes 1. When the limiting protrusions 10 on the grounding pad 4 interact with the different limiting holes 9 on the evaporator tube sheet 2, the angles between the length direction of the grounding pad 4 and the length direction of the evaporator tube sheet 2 are different, which can accommodate grounding wires 8 with different wiring directions, allowing the grounding wires 8 to bend naturally and avoiding excessive bending. In specific applications, the appropriate limiting holes 9 and grounding pads 4 can be selected according to the wiring direction.

[0058] It should be noted that at least two limiting protrusions 10 can also be provided in the transition portion 7 of the grounding pad 4, with each limiting protrusion 10 spaced apart along the length of the grounding pad 4. The distance between different limiting protrusions 10 and the connecting hole 11 is different. In this case, the distance between the limiting protrusion 10 and the connecting hole 11 can correspond one-to-one with the distance between the limiting hole 9 and the grounding hole 1. This allows the same grounding pad 4 to be adapted to different limiting holes 9, and the same grounding pad 4 can have different installation directions to adapt to different wiring directions, thus increasing its adaptability.

[0059] In some other embodiments of this utility model, the limiting hole 9 is provided on the evaporator tube plate 2, and the limiting protrusion 10 is provided on the transition part 7. Each grounding hole 1 is provided with at least two limiting holes 9, and the limiting holes 9 are distributed at intervals along the circumference of the grounding hole 1.

[0060] The distance between the different limiting holes 9 and the grounding hole 1 is the same, and the angle between the straight line containing the different limiting holes 9 and the grounding hole 1 and the length direction of the evaporator tube plate 2 is different. For the same grounding pad 4, it can be adapted to different limiting holes 9, and the same grounding pad 4 can have different installation directions, which can adapt to different wiring directions and has strong adaptability.

[0061] In this embodiment of the invention, the limiting protrusion 10 can be disposed on one side edge of the transition portion 7, and the limiting protrusion 10 is formed by bending. This configuration simplifies the processing technology, allows for mass production using molds, and reduces processing costs.

[0062] In this embodiment, at least two grounding holes 1 are provided on the evaporator tube sheet 2. Each grounding hole 1 is distributed at intervals along the length direction of the evaporator tube sheet 2, and each grounding hole 1 is provided with a corresponding limit structure.

[0063] Different air conditioner models require different numbers of grounding wires 8, and correspondingly, the number of grounding holes 1 on the evaporator tube plate 2 varies. In this embodiment, multiple grounding holes 1 are provided on the evaporator tube plate 2. For models requiring fewer grounding wires 8, the appropriate number and location of grounding holes 1 can be selected as needed. For models where the required number of grounding wires 8 is the same as the number of grounding holes 1 on the evaporator tube plate 2, all grounding holes 1 on the evaporator tube plate 2 can be used. In other words, the evaporator tube plate 2 is suitable for both models requiring fewer grounding wires 8 and models requiring more grounding wires 8, thus improving the versatility of the evaporator tube plate 2.

[0064] When at least two grounding wires 8 need to be connected to the evaporator tube sheet 2, the angles of each grounding pad 4 can be made the same, improving the consistency of the grounding mechanism and enhancing the standardization of the product.

[0065] In this embodiment of the present invention, the second connecting part includes a connecting part body and a clamping piece 6.

[0066] The connecting part body is connected to the transition part 7, and the clamping part 6 is provided on the connecting part body. The clamping part 6 is deformable to clamp and fix the grounding wire 8 to the connecting part body, thereby realizing the connection between the grounding wire 8 and the grounding pad 4.

[0067] The clamping part 6 can be configured as a strip structure. The clamping part 6 is provided on both sides of the connecting part body. The clamping part 6 clamps the grounding wire 8 from opposite sides of the connecting part body, which can improve the stability of the connection structure between the second connecting part and the grounding wire 8.

[0068] In this embodiment, the outline of the first connecting part 5 is arc-shaped, and the edge of the first connecting part 5 is smoothly connected to the edge of the transition part 7. The outline of the first connecting part 5 is consistent with the outline of the cap end of the grounding nail 3, which can improve the aesthetics of the air conditioner's grounding mechanism.

[0069] On the other hand, this utility model embodiment also provides an air conditioner, including the grounding mechanism of the air conditioner provided in any of the above embodiments. The grounding mechanism of the air conditioner provided in any of the above embodiments can restrict the rotation of the grounding pad 4 and the grounding wire 8 when the grounding nail 3 is installed, avoiding pulling on the grounding wire 8. Therefore, the air conditioner in this embodiment has the advantages of reliable grounding and a high safety factor. The derivation process of the beneficial effects of the air conditioner in this utility model embodiment is largely similar to the derivation process of the beneficial effects of the grounding mechanism of the air conditioner described above, and therefore will not be repeated here.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
