Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a wiring structure for a grille-mounted fan, an outdoor air conditioning unit, and an air conditioner. Background Technology

[0002] An outdoor unit of an air conditioner generally includes a casing and a fan installed inside the casing. If the axial fan is installed on the grille, the motor bracket can be eliminated, which not only saves costs but also eliminates the wind resistance caused by the motor bracket blocking the airflow.

[0003] However, when the fan is installed directly on the grille, the wiring will start from the center of the grille and need to reach the electrical control area behind the fan. The motor wiring can no longer pass through the groove of the motor bracket as before.

[0004] Therefore, how to provide a wiring structure for a grille-mounted fan that minimizes wind resistance and avoids interference with the fan is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a wiring structure for a grille-mounted fan, an outdoor air conditioning unit, and an air conditioner, to at least solve one of the aforementioned problems in the prior art.

[0006] This utility model provides a wiring structure for a grille-mounted fan, which is disposed on a grille and a front cover, wherein the front cover has a through hole; the grille includes a frame, a grille body, and a central portion, wherein the grille body is disposed between the frame and the central portion; the frame is connected to the front cover, and there is a sandwich space between them; the grille body and the central portion are located at the through hole, and the wiring structure includes:

[0007] The first wiring groove extends outward from the outer periphery of the central part to the position of the frame;

[0008] The second wiring channel is provided along one side of the frame, and the second wiring channel is connected to the first wiring channel;

The above wiring method does not obstruct the air duct and there is no risk of the motor wire coming into contact with the fan.

[0011] According to the wiring structure of a grille-mounted fan provided by this utility model, the grille body includes:

[0012] Multiple annular grids are concentrically arranged with the central portion;

[0013] Multiple strip grids are evenly distributed along the circumference of the central part. One end of each strip grid is connected to the outer side of the central part, and the other end passes through multiple annular grids and is connected to the frame. The first wiring groove replaces one of the strip grids.

[0014] By setting up the above structure, the original grid structure can be modified as little as possible, allowing the fan to be directly installed on the grid wiring.

[0015] According to the wiring structure of the grille-mounted fan provided by this utility model, the first wiring groove is a U-shaped groove.

[0016] With the above structure, the U-shaped groove can effectively limit the motor wires, preventing wind resistance caused by misalignment or interference with the fan.

[0017] According to the present invention, a wiring structure for a grid-mounted fan is provided, wherein the second wiring groove is formed by the side of the frame and vertical ribs arranged along the side, a first notch is provided between the vertical rib and the first wiring groove, and a second notch is provided between the vertical rib and the interlayer space.

[0018] With the above structural design, the vertical ribs and the edge of the frame form a second wiring channel, which is simple to manufacture and easy to process.

[0019] According to the wiring structure of the grille-mounted fan provided by this utility model, the vertical ribs are arranged parallel to the side and the vertical distance between them is 0.8-1.2cm.

[0020] The above structure provides sufficient space for the motor wiring.

[0021] According to the wiring structure of the grille-mounted fan provided by this utility model, the vertical ribs are provided with rounded corners at both the first notch and the second notch.

[0022] The above structure facilitates the movement of motor wires from the first wiring channel into the second wiring channel, and from the second wiring channel into the interlayer space.

[0023] According to the wiring structure of the grille-mounted fan provided by this utility model, it further includes a groove, which is formed on the center part and corresponds to the position of the first wiring groove.

[0024] The above structure allows the motor wires to easily enter the first wiring groove from the lead-in port, avoiding compression of the motor wires in the center.

[0025] According to the wiring structure of the grille-mounted fan provided by this utility model, the grille body and the central part are combined into a circle, the frame is square, and the corners of the frame and the front cover form the interlayer space.

[0026] By setting up the above structure, the original grating structure is preserved as much as possible, reducing mold costs.

[0027] This utility model also provides an outdoor unit for an air conditioner, including a grille, a front cover, and a wiring structure for mounting a fan on the grille as described above, wherein the wiring structure for mounting a fan on the grille is disposed on the grille and the front cover.

[0037] 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.

[0038] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] The following is combined Figures 1-3 This utility model describes a wiring structure for a grille-mounted fan, which is disposed on a grille 10 and a front cover 20. The front cover 20 has a through hole 21. The grille 10 includes a frame 11, a grille body 12, and a center part 13. The grille body 12 is disposed between the frame 11 and the center part 13. The frame 11 is connected to the front cover 20, and there is a sandwich space between the two. The grille body 12 and the center part 13 are located at the through hole 21.

[0040] The wiring structure includes a first wiring groove 1, a second wiring groove 2, and a wiring outlet 3. The first wiring groove 1 extends outward from the outer periphery of the center portion 13 to the frame 11. The motor wire is embedded inside the first wiring groove 1 to prevent the motor wire from contacting other components, reducing the risk of short circuits and damage. The outer side connects to the grille body 12. The second wiring groove 2 is located along one side of the frame 11 and communicates with the first wiring groove 1; the wiring outlet 3 is opened on the front cover 20 and communicates with the second wiring groove 2.

[0041] The wiring structure for a grille-mounted fan provided by this utility model allows for the routing of the motor wires of the fan installed on the grille. The motor wires start from the fan, first pass through the first wiring groove 1, then through the second wiring groove 2, and then enter the interlayer space between the frame 11 and the front cover 20. Finally, they enter the electrical control area inside the front cover 20 through the outlet hole 3. During the wiring process, the air duct will not be obstructed, and there is no risk of the motor wires coming into contact with the fan, thus meeting the technical requirements for the fan to be directly mounted on the grille.

[0042] In some feasible embodiments of this utility model, the grid body 12 includes multiple annular grids 121 and multiple strip grids 122. The multiple annular grids 121 are concentrically arranged with the central part 13, which can enhance the overall structural stability of the grid, effectively disperse external forces, resist deformation, and thus extend the service life of the grid. The multiple strip grids 122 are evenly distributed along the circumference of the central part 13, and the annular grids 121 and strip grids 122 are interwoven to form a stable and orderly whole. One end of each strip grid 122 is connected to the central part 13, and the other end passes through multiple annular grids 121 and is connected to the frame 11; this evenly distributed design makes the grid body 12 have consistent strength and stability in all directions. When the grid body 12 is subjected to external forces, the strip grids 122 can evenly transmit the force to the entire structure, avoiding damage caused by local stress concentration. The first wiring groove 1 replaces one of the strip grids 122. While undertaking the function of wiring, the first wiring groove 1 also serves as the function of the strip grid 122, reducing additional structural components and making the entire grid structure more concise and compact. At the same time, the motor wire can extend more smoothly from the center 13 along the first wiring groove 1 to the frame 11, avoiding the detours and bends of the line, reducing the line length and resistance, and improving the power transmission efficiency. Moreover, the first wiring groove 1 is evenly distributed with other strip grids 122, making the appearance of the grid more neat and beautiful. The motor wire is hidden in the first wiring groove and will not affect the grid body 12.

[0043] In some feasible embodiments of this utility model, the first wiring trough 1 is a U-shaped trough with the opening facing upwards, so that the motor wire can be easily embedded in it. Compared with a closed wiring trough, the U-shaped trough greatly reduces the difficulty of wiring installation. Installers can quickly and accurately place the motor wire in place without the need for complicated tools or cumbersome operations, which greatly improves the installation efficiency and also reduces the risk of wiring damage caused by installation difficulties.

[0044] In some feasible embodiments of this utility model, the second wiring trough 2 is formed by the side of the frame 11 and the vertical ribs 14 arranged along the side. A first notch 4 is provided between the vertical ribs 14 and the first wiring trough 1, and a second notch 5 is provided between the vertical ribs 14 and the interlayer space. The second wiring trough 2 makes full use of the structural features of the frame 11. By adding the vertical ribs 14 to form a channel together, no extra space is required, realizing the compactness and rationality of the structure. It not only enhances the overall strength of the frame 11, but also provides a dedicated wiring space for the motor wires, avoiding interference between the wires and other components. The setting of the first notch 4 allows the motor wires to smoothly transition from the first wiring trough 1 to the second wiring trough 2. The seamless connection design not only reduces the bending angle of the wires and reduces wire loss, but also avoids the problem of jamming or damage caused by poor wire transition, ensuring the stability and efficiency of power transmission. The second gap 5 establishes a convenient passage between the second wiring trough 2 and the interlayer space. When the motor wire needs to enter the interlayer space from the second wiring trough 2 and finally pass out through the outlet hole 3, the second gap 5 provides a reasonable path selection.

[0045] In some feasible embodiments of this utility model, the vertical ribs 14 are arranged parallel to the side of the frame 11 and the vertical distance between them is 0.8-1.2cm. This ensures that the vertical ribs 14 can fully play their supporting role, while avoiding the problem that the connection between the two is too tight due to the small distance, which would cause stress concentration in the material. It also prevents the failure to form an effective synergistic force-bearing system due to the large distance, making the entire grid structure more stable and reliable when resisting external impacts.

[0046] In some feasible embodiments of this utility model, the vertical rib 14 is provided with rounded corners at both the first notch 4 and the second notch 5. The rounded corners can effectively prevent the wire from directly contacting the sharp edge of the vertical rib 14, greatly reducing the risk of insulation layer damage caused by friction or compression at the turning point of the wire. This not only extends the service life of the motor wire, but also fundamentally reduces the safety hazards caused by wire damage, ensuring the long-term stable operation of the fan system.

[0047] In some feasible embodiments of this utility model, a groove 6 is also included. The groove 6 is formed on the central portion 13 and corresponds to the position of the first wiring groove 1. When the motor wire is connected from the starting end of the fan, it can be initially positioned and arranged along the groove 6, and then seamlessly connected into the first wiring groove 1. This process allows the motor wire to remain neat and orderly from the beginning, avoiding the phenomenon of messy tangling of the wire near the central portion 13, making the entire wiring layout more standardized and aesthetically pleasing.

[0048] In some feasible embodiments of this utility model, the grille body 12 and the center part 13 are combined into a circle, the frame 11 is square, and the corners of the frame 11 form a sandwich space with the front cover 20. The above design cleverly utilizes the structural gaps, neither occupying the effective ventilation or decorative area on the front of the grille, nor obstructing the wiring space for motor wires and other lines. The square frame 11 facilitates precise docking and fixing with the front cover 20, making the installation process simple and efficient; while the sandwich space is located at the corner of the frame 11, maintenance personnel can easily access the wiring during later wiring inspection or replacement without disassembling a large number of parts, greatly shortening maintenance time and reducing maintenance costs.

[0049] In summary, the wiring structure for the grille-mounted fan provided by this utility model ensures that the motor wires do not obstruct the air duct during wiring, and there is no risk of the motor wires coming into contact with the fan, thus meeting the requirement for the fan to be directly installed on the grille.

[0050] The second aspect of this utility model is to provide an outdoor unit for an air conditioner, including a grille, a front cover, and a wiring structure for mounting a fan on the grille as described above, wherein the wiring structure for mounting a fan on the grille is disposed on the grille and the front cover.
