Technical Field
[0001] This application relates to the field of electromagnetic heating technology, specifically to the field of a support for an easy-to-twist square coil disc. Background Technology
[0002] Induction cookers are widely used household appliances. Their working principle is based on electromagnetic induction heating technology, which uses a heating coil to generate an alternating magnetic field, creating eddy currents at the bottom of the metal cookware to achieve rapid heating. Therefore, the core component is the heating coil, and its structural design and manufacturing process directly affect the heating efficiency, heat distribution uniformity, and overall performance of the induction cooker.
[0003] Traditional induction cookers mostly use a circular spiral coil structure, and the winding process for this structure is mature. However, as users demand more diverse cooking methods, such as multi-zone heating and compatibility with irregularly shaped cookware, square coils are gradually gaining attention due to their advantages such as diverse heating space design and ease of modular integration.
[0004] However, its manufacturing process, especially the winding process, is limited. Current methods rely on multi-axis winding equipment with XY-axis linkage for segmented winding. This approach results in high equipment and manufacturing costs, leading to low product cost-effectiveness.
[0005] Therefore, how to simplify the winding process of square coils, reduce dependence on high-end equipment, and improve production efficiency and product quality has become a key technical problem that urgently needs to be solved in the current coil manufacturing field. Summary of the Invention
[0006] To address the aforementioned problems, this application proposes an easy-to-wind square coil support. By optimizing the geometry and winding structure of the support, the square coil can be continuously wound in a single winding direction, avoiding the complex processes and high costs associated with traditional multi-axis winding.
[0007] To achieve the above objectives, the present application adopts the following technical solution:
[0008] A square coil holder for easy-to-wind wire includes a square outer frame and a circular fixing ring disposed in the middle. The square outer frame and the fixing ring are fixedly connected by multiple support ribs. The support ribs include a first rib in the diagonal direction of the square outer frame and a second rib in the center direction of the frame of the square outer frame. The support ribs are provided with multiple wire clamps.
[0009] It also includes a reinforcing rib disposed between the square outer frame and the fixing ring, wherein the inner circumference of the reinforcing rib is circular and the outer circumference is square;
[0010] It also includes an inner ring area formed between the fixed ring and the reinforcing rib, and an outer ring area formed between the square outer frame and the reinforcing rib, which is capable of coaxially winding a coil.
[0011] Thus, by setting a circular fixing ring in the middle and setting a cross-shaped multi-dimensional support rib around the fixing ring and the square outer frame, the overall rigidity is enhanced. Combined with the design of setting reinforcing ribs and wire clamps, a reasonable layout is provided for the orderly winding of the coil.
[0012] The inner ring area of the reinforcing rib is circular and can be coaxially wound into a coil. The outer ring area of the reinforcing rib is formed by the setting of the first rib, which forms a relatively circular winding area. Coaxial winding of the outer ring area can be achieved by simply contracting and releasing the coil in the vertical Z-axis direction when winding the corresponding second rib. This allows the square coil to be continuously wound in a single winding axis direction, avoiding the complex process and high cost of traditional multi-axis winding.
[0013] In some possible implementations, a support ring is provided between the fixing ring and the reinforcing rib, and the end of the first rib is fixed to the support ring.
[0014] In some possible implementations, a support post is provided at the first rib between the support ring and the fixing ring.
[0015] In some possible implementations, the wire clamps on the outer periphery of the support ring are hollow clamps.
[0016] In some possible implementations, the reinforcing ribs are formed as wire clips at their four corners, serving as the first ribs.
[0017] In some possible implementations, the wire clip extends outward from both sides of the outer ring area of the first rib, protruding from the first rib.
[0018] In some possible implementations, the number of wire clips in the outer ring area of the first rib and the second rib is the same, the spacing of the wire clips in the outer ring area is the same in the second rib, and the spacing of the wire clips in the first rib increases outward from the periphery.
[0019] In some possible implementations, the back of the support rib is provided with a first hollow cavity into which a magnetic strip can be embedded.
[0020] In some possible implementations, the connection between the support rib and the square outer frame is provided with a second hollow cavity that communicates with the first cavity, and the connection between the second rib and the fixing ring is provided with a third hollow cavity that communicates with the first cavity.
[0021] In some possible implementations, the system also includes two power cord clamps disposed on the square outer frame, one on each side of the second rib. Attached Figure Description

[0028] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:
[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0030] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.
[0031] Traditional coil winding technology uses a circular coil, requiring only a feed head and an X-axis robotic arm. The coil is wound by rotating the coil, making it a mature process with low equipment cost and high efficiency. Specifically, the feed head is fixed to a vertically movable (Z-axis movable) robotic arm responsible for feeding and retrieving the coil. The X-axis robotic arm moves unidirectionally as the coil is wound to complete the winding process.
[0032] However, when adopting such Figure 1When the coil tray support of the square outer frame 1 shown is used, existing disc-based processes make it difficult to complete the coil winding by rotating the coil tray support. Therefore, a multi-axis winding device with XY-axis linkage is used for segmented winding. This increases the cost of processing equipment, and the processing efficiency is low because the robot arm drives the wire feeding head to move, resulting in a low product cost-performance ratio.
[0033] Please continue to refer to this. Figure 1 This application discloses an easy-to-wind square coil support, comprising a square outer frame 1 and a circular fixing ring 2 disposed in the middle of the square outer frame 1. The square outer frame 1 and the fixing ring 2 are fixedly connected by multiple support ribs 3. Therefore, a heat dissipation space is formed between the support ribs 3. The design of the heat dissipation space can prevent the decrease in magnetic permeability and heating efficiency caused by the high temperature generated by the coil. This application mainly focuses on the innovative design of the wound coil, and the heat dissipation is not described in detail. It is mainly for descriptive purposes. Through the design of the support ribs 3, this application also has a heat dissipation space.
[0034] Specifically, the support rib 3 includes a first rib 31 in the diagonal direction of the square outer frame 1 and a second rib 32 in the center direction of the edge of the square outer frame 1, forming a cross-shaped multi-dimensional support rib with the fixing ring 2 as the circumference center, which enhances the overall rigidity.
[0035] Furthermore, each support rib 3 is equipped with multiple wire clamps 4, which fix the coil during winding and are evenly distributed along the longitudinal direction of the support rib 3. Further, a reinforcing rib 5 is provided between the square outer frame 1 and the fixing ring 2. The inner circumference of the reinforcing rib 5 is circular, and the outer circumference is square. Specifically, arc-shaped ribs are added at diagonal points, ensuring that the inner circle remains coaxial with the fixing ring 2, and the outer circumference is aligned with the square outer frame 1. Thus, the combination of the reinforcing ribs 5 and the wire clamps 4 provides a reasonable layout for the orderly winding of the coil.
[0036] Specifically, an inner ring area Q1 is formed between the fixing ring 2 and the reinforcing rib 5, allowing for coaxial winding of the coil. Since the inner ring of the reinforcing rib 5 is circular, winding can be completed directly using the process for circular coil discs. The outer ring area Q2, formed between the square outer frame 1 and the reinforcing rib 5, is actually arc-shaped at the junction of the square outer frame 1 and the first rib 31.
[0037] Therefore, a circular space is formed at the four corners of the square outer frame 1, and the reinforcing rib 5 forms the line clamp 4 of the first rib 31 at the four corners. This allows the square coil disk to be rotated and the coil to be wound. Coaxial winding of the outer ring area can be achieved by contracting and releasing the coil in the vertical Z-axis direction when winding the corresponding second rib 32. This enables the square coil to be continuously wound in a single winding axis direction, avoiding the complex process and high cost of traditional multi-axis winding.
[0038] Furthermore, the number of wire clamp strips 4 in the outer ring region Q2 of the first rib 31 and the second rib 32 is the same. The spacing of the wire clamp strips 4 in the outer ring region Q2 of the second rib 32 is the same, and the spacing of the wire clamp strips 4 in the first rib 32 increases outward from the periphery, so that the coil can be accurately clamped onto the wire clamp strips 4 of the second rib 32. Please refer to the reference. Figure 6 In some embodiments, the wire clamp 4 extends outward from both sides of the outer ring area Q2 of the first rib 31, protruding from the first rib 31, so as to become a clamping point when winding the wire, which can avoid the problem of large wire jump at the four corners and the coil easily jumping out.
[0039] Furthermore, a support ring 6 is provided between the fixing ring 2 and the reinforcing rib 5, and the end of the first rib 31 is fixed to the support ring 6. This avoids the problem of the first rib 1 and the second rib 2 occupying heat dissipation space around the fixing ring 2. Simultaneously, a support post 61 is provided at the first rib 31 between the support ring 6 and the fixing ring 2 to enhance the support strength. The inner side of the support ring 6 is then fixed by wrapping with the wire clips 4 of the second rib 32.
[0040] As a reinforcement measure for the wire clamp 4 during the coil winding process, a hollow clamp 41 is set on the outer periphery of the support ring 6. Specifically, based on the design of a thicker wire clamp 4, a hollow structure is set to effectively improve the bending and torsional stiffness, so that it can remain stable and undeformed when subjected to a large clamping force.
[0041] Please refer to Figures 2 to 5 A first hollow cavity 301 for embedding magnetic strips 100 is provided on the back of the support rib 3. In this way, the magnetic strips 100, which are spaced apart by the support rib 3, can balance the magnetic conduction effect and heat dissipation effect, while significantly reducing the manufacturing cost.
[0042] Furthermore, a second hollow cavity 302 communicating with the first cavity 301 is provided at the junction of the supporting rib 3 and the square outer frame 1. A third hollow cavity 303 communicating with the first cavity 301 is provided at the junction of the second rib 302 and the fixing ring 2. The second hollow cavity 302 and the third hollow cavity 303 are arranged facing the coil side, which will form a radiation shielding layer on the outer periphery of the coil disk, while also strengthening the magnetic permeability of the outer periphery, improving heating efficiency, and making the overall coil disk heat up more evenly. On the inner side, a heat dissipation space is provided to further improve the heating efficiency in the middle.
[0043] In some embodiments, the magnetic strip 100 can be pre-installed on the support rib 3 to form an integral coil support. After the coil is wound, it will be connected to a power cord (not shown in the figure). Therefore, a power cord clamp 11 is provided on the square outer frame 1. The clamp 11 is divided into an inner ring and an outer ring of power cords, which are respectively set on both sides of the second rib 32. The power cord of the inner ring can be led out from the back of the integral support and clamped separately from the power cord of the outer ring.
[0044] As stated above, this case protects a square coil holder for easy-to-tangle wires, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
