Description

Technical Field

[0001] This invention relates to the field of cooktop technology, and in particular to a cooktop structure, a cooktop manufacturing method, and a cooktop. Background Technology

[0002] Cooktops are common kitchen cooking utensils in daily life. With the improvement of people's living standards, users generally choose built-in cooktops in modern decoration. The reason is that the glass of the cooktop of the built-in cooktop can be close to the same plane as the countertop, thus saving cooktop space, improving the overall aesthetics of the kitchen, and making it easy to clean.

[0003] To reduce costs, the frame of some built-in cooktops is fixed by splicing multiple frame strips. Since the frame strips are mostly fixed with bolts, the mechanical stress after the bolts are tightened can cause gaps or steps at the connection points of adjacent frame strips after assembly, resulting in rough edges at the splicing points of the frame and affecting the aesthetics of the frame. Summary of the Invention

[0004] Therefore, it is necessary to provide a cooktop structure, cooktop manufacturing method, and cooktop that can effectively improve the problems of gaps or steps that easily occur at the connection points of the current cooktop frame formed by splicing multiple frame strips.

[0005] This application first provides a cooktop structure, including a flat support and a cooktop glass. The flat support includes multiple strip-shaped splicing segments spliced ​​and fixed in a horizontal direction. Each splicing segment includes a fixing bracket and a connecting part that are fixed to each other. The cooktop glass is fixed in the fixing bracket.

[0006] The first connecting part is formed by having a through hole in one of the two adjacent connecting parts, and the second connecting part is formed by having a fixing hole corresponding to the through hole. The flat bracket also includes a limiting member, which includes a limiting part, a positioning part, and a fixing part that are fixed in sequence. The fixing part passes through the through hole and is fixed to the inner wall of the fixing hole. The positioning part is inserted into the through hole and fits against the second connecting part along the axial direction of the through hole. There is a gap between the positioning part and the inner wall of the through hole along the radial direction of the through hole, and there is a gap between the limiting part and the first connecting part along the axial direction of the through hole.

[0007] In some embodiments, the fixing hole is a threaded hole, and the limiting member is a limiting bolt;

[0008] The stud of the limiting bolt is threadedly connected to the threaded hole, and the stud is fitted with the second connecting part along its own length direction. The nut of the limiting bolt is the limiting part.

[0009] In some embodiments, the stud includes a large-diameter section near the nut and a small-diameter section away from the nut. The large-diameter section is the limiting part, and the small-diameter section is the fixing part. The length of the large-diameter section is greater than the depth of the through hole, and the diameter of the large-diameter section is greater than that of the small-diameter section, so as to form a stepped surface between the two. The small-diameter section is threadedly connected to the threaded hole, and the stepped surface fits against the second connecting part.

[0010] In some embodiments, the cooktop structure further includes a sealing ring surrounding the cooktop glass, the sealing ring being located between the fixing bracket and the cooktop glass and being tightly abutted against both in the horizontal direction.

[0011] In some embodiments, each of the splicing segments includes a flange, a fixing bracket, and a connecting portion that are fixed in sequence;

[0012] The cooktop structure is installed on the countertop, the flanged bottom surface is attached to the upper surface of the countertop to support the flush bracket, and the fixed bracket is located in the cooktop groove of the countertop.

[0013] In some embodiments, a mating part is fixed to the inner side of the fixed bracket, the upper surface of the mating part is flush with the flange, and the inner side of the mating part is inclined outward from top to bottom. The edge of the upper surface of the cooktop glass in the circumferential direction has a chamfer that corresponds to and fits the inner side of the mating part.

[0014] In some embodiments, the bottom surface of the fixed bracket is provided with at least two support portions of the same height, the bottom surface of the cooktop glass is in contact with each of the support portions, an adhesive cavity is formed between two adjacent support portions, and there is a gap between the adhesive cavity and the bottom surface of the cooktop glass.

[0015] In some embodiments, the cooktop structure further includes an elastic bracket, one end of which is fixed to the connecting portion and the other end of which is fixed to the cooktop chassis.

[0016] In some embodiments, the flat bracket includes four splicing segments with the same cross-section. Each connecting part includes a connecting plate and a bolt post. The connecting plate is fixed to the fixed bracket, and the bolt post is fixed to the outer side of the connecting plate. The bolt post has threaded holes at both ends. In one pair of splicing segments, the connecting plate has through holes at both ends.

[0017] In some embodiments, two adjacent splicing segments are spliced ​​at an angle at the corner of the flat bracket, and the tip of the angle of the splicing segment is rounded.

[0018] A second aspect of this application provides a method for manufacturing a cooktop, used to manufacture the aforementioned cooktop structure, comprising the steps of:

[0019] S100. Two adjacent splicing segments form a group, and limiting components are installed in the corresponding through holes and fixing holes of each group of two splicing segments for pre-limiting;

[0020] S200. Open the moving plate of the assembly fixture and install each set of splicing sections after pre-limiting onto the moving plate and the fixed plate;

[0021] S300. Apply adhesive to the bottom surface of the fixing bracket along each splicing section, and place the cooktop glass on the bottom surface of the fixing bracket;

[0022] S400. The moving plate of the clamping assembly fixture presses against each splicing segment to complete the splicing;

[0023] S500. After the adhesive has cured, remove the cooktop structure and install the limiting components into the remaining corresponding through holes and fixing holes.

[0024] A third aspect of this application provides a cooktop including the aforementioned cooktop structure.

[0025] The aforementioned cooktop structure uses a limiting component to pre-limit the movement between adjacent splicing sections. Then, in conjunction with assembly fixtures, the cooktop glass is fixed to the mounting bracket to complete the fixation. After the pre-limiting is completed...

[0026] On the one hand, since the limiting component only serves to limit the movement and will not press the first connecting part and the second connecting part together, no connecting stress will be generated between the two adjacent connecting parts. Therefore, when the cooktop glass is subsequently fixed to the fixed bracket, it can ensure that the flat bracket and the cooktop glass are firmly fixed, while avoiding the generation of splicing steps.

[0027] On the other hand, pre-limiting the connection between the splicing segments in pairs allows for only a small amount of movement between the splicing segments, preventing large displacement and facilitating further fixation of the rear cooktop glass. Attached Figure Description

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention 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 this invention.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] It is important to note that when using screws to gradually tighten the long and short frames of a flat frame, assuming the screws penetrate the long frame and connect to the short frame via threads, the short frame will rotate along with the screw under the torque of the threads. When finally tightened, the connecting end faces between the long and short frames will generate corresponding friction (or additional restraining force) to counteract the torque of the threads, thus creating connection stress between the long and short frames. The presence of connection stress can easily cause the long and short frames to not be completely flush, forming a step.

[0048] Please combine Figures 1 to 4 As shown, this application first provides a cooktop structure, including a flat support 10 and a cooktop glass 20. The flat support 10 includes multiple strip-shaped splicing segments 10a that are spliced ​​and fixed in the horizontal direction. Each splicing segment 10a includes a fixed support 12 and a connecting part 13 that are fixed to each other. The cooktop glass 20 is fixed in the fixed support 12. The first connecting part 13a has a through hole 131a in two adjacent connecting parts 13, and the second connecting part 13b has a fixing hole corresponding to the through hole 131a. The flat support 10 also includes a limiting member, which includes a limiting part, a positioning part, and a fixing part that are fixed in sequence. The fixing part passes through the through hole 131a and is fixed to the inner wall of the fixing hole. The positioning part is inserted into the through hole 131a and fits against the second connecting part 13b along the axial direction of the through hole 131a. There is a gap between the positioning part and the inner wall of the through hole 131a in the radial direction of the through hole 131a. There is a gap between the limiting part and the first connecting part 13a in the axial direction of the through hole 131a.

[0049] In this application, a limiting component is used to pre-limit the two adjacent splicing segments 10a, and then the cooktop glass 20 is fixed to the fixed bracket 12 with the help of the assembly tool to complete the fixation. After the pre-limiting is completed, on the one hand, since the limiting component only plays a limiting role and will not press the first connecting part 13a and the second connecting part 13b together, no connection stress will be generated between the two adjacent connecting parts 13. Therefore, when the cooktop glass 20 is subsequently fixed to the fixed bracket 12, it can ensure that the flush bracket 10 and the cooktop glass 20 are firmly fixed, while avoiding the generation of splicing steps. On the other hand, the pre-limiting of the splicing segments 10a by connecting them in pairs can make the splicing segments 10a have only a small amount of movement, without large displacement, which facilitates the further fixation of the cooktop glass 20.

[0050] Preferably, the cooktop glass 20 is fixed to the fixing bracket 12 by adhesive; of course, in some other embodiments, the cooktop glass 20 and the fixing bracket 12 can also be fixed by snap-fit ​​or other commonly used fixing methods, which will not be listed here.

[0051] Specifically, after the pre-limiting is completed, the connection stress is generated at the contact position between the positioning part and the second connecting part 13b. After the pre-limiting is completed, there is a certain amount of movement between the limiting member and the first connecting part 13a. Therefore, the limiting bolt 14 will not squeeze the first connecting part 13a when tightened, thereby preventing the generation of connection stress between the two adjacent connecting parts 13.

[0052] It is worth mentioning that after the cooktop glass 20 is fixed to the fixed bracket 12, the cooktop structure has been completely fixed. The limiting parts between the pre-limited splicing sections 10a can be installed or not installed according to actual needs. If not installed, it will not affect the overall fixation of the cooktop structure. If installed, the splicing strips 10a can be connected and fixed to form a whole, preventing them from falling during transportation.

[0053] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the fixing hole is a threaded hole 132a, and the limiting member is a limiting bolt 14; the stud 141 of the limiting bolt 14 is threadedly connected to the threaded hole 132a, and the stud 141 fits against the second connecting part 13b along its own length direction, and the nut 142 of the limiting bolt 14 is a limiting part.

[0054] After the pre-limiting is completed, the stud 141 fits against the second connecting part 13b along its own length direction, there is a gap between the nut 142 and the first connecting part 13a, and there is a gap between the outer peripheral surface of the stud 141 and the inner wall of the through hole 131a.

[0055] Of course, in some other embodiments, the limiting member can also be fixed to the fixing hole in other ways, such as by interfering with the fixing part and the fixing hole to complete the fixation, etc. This application will not give examples of them one by one.

[0056] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the stud 141 includes a large-diameter section 141b near the nut 142 and a small-diameter section 141a away from the nut 142. The large-diameter section 141b is a limiting part, and the small-diameter section 141a is a fixing part. The length of the large-diameter section 141b is greater than the depth of the through hole 131a, and the diameter of the large-diameter section 141b is greater than that of the small-diameter section 141a, so as to form a stepped surface 141c between the two. The small-diameter section 141a is threadedly connected to the threaded hole 132a, and the stepped surface 141c fits against the second connecting part 13b.

[0057] The limiting bolt 14 is tightened so that the stress is generated at the stepped surface 141c. The diameter of the large-diameter section 141b is smaller than the inner diameter of the through hole 131a, thus creating a circumferential gap between the large-diameter section 141b and the through hole 131a. The length of the large-diameter section 141b is greater than the depth of the through hole 131a, creating a gap between the nut 142 and the first connecting part 13a. These two gaps provide the amount of movement when tightening the screw, preventing stress from being generated between the two connecting parts 13. Of course, in other embodiments, the limiting bolt 14 can have other structures, as long as it is tightened to the second connecting part 13b, has some movement with the first connecting part 13a, and can limit the displacement of the first connecting part 13a.

[0058] It is worth mentioning that in the above embodiment, there will inevitably be a gap between the fixed bracket 12 and the cooktop glass 20. Therefore, the fitting precision between the two is required. If the size difference between the two is too large, the gap will be too large. On the one hand, it will affect the overall aesthetics of the cooktop structure. On the other hand, water may seep into the cooktop through the gap, which may pose a certain safety hazard.

[0059] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the cooktop structure also includes a sealing ring 30 surrounding the cooktop glass 20, the sealing ring 30 being located between the fixed bracket 12 and the cooktop glass 20 and being tightly attached to both in the horizontal direction.

[0060] By filling the upward gap between the fixed bracket 12 and the cooktop glass 20 with the sealing ring 30, in addition to preventing water from seeping into the cooktop through the upward gap and playing a waterproof role, it can also act as a buffer between the fixed bracket 12 and the cooktop glass 20 to prevent abnormal noises or shaking of the cooktop structure after long-term use.

[0061] In some embodiments, the cross-section of the sealing ring 30 can be I-shaped, L-shaped or other shapes, as long as the sealing ring 30 can fit tightly against the inner wall of the fixing bracket 12, thereby playing a waterproof and cushioning role.

[0062] In some embodiments, the top of the sealing ring 30 is flush with the upper surface of the flange 11. It is easy to understand that if the sealing ring 30 protrudes from the upper surface of the flange 11, it will affect the drainage of water when cleaning the cooktop glass 20. Conversely, if the sealing ring 30 is recessed into the top seam, water will remain in the top seam and will be difficult to clean.

[0063] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, a mating part 121 is fixed inside the fixed bracket 12. The upper surface of the mating part 121 is flush with the flange 11, and the inner side of the mating part 121 is inclined outward from top to bottom. The edge of the upper surface of the stove glass 20 in the circumferential direction has a chamfer that corresponds to and fits the inner side of the mating part 121.

[0064] By fitting the mating part 121 with the chamfer of the cooktop glass 20, the impact of the upward-facing seam can be weakened, increasing the difficulty of water leakage, while also optimizing the visual effect of the joint. The inner surface of the mating part 121 is inclined outward from top to bottom. The inner surface of the mating part 121 can be flat or curved, as long as it can fit snugly with the chamfer of the cooktop glass 20.

[0065] Preferably, a mating part 121 is fixed on the inner side of the fixed bracket 12, and a sealing ring 30 is also provided between the fixed bracket 12 and the cooktop glass 20. By setting two structures at the same time, the waterproof effect is further optimized.

[0066] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the upper surface of the flange 11 slopes downward from the inside to the outside to reduce residual water accumulation on the surface of the flange 11 and further reduce the difficulty of cleaning.

[0067] Adhesive bonding is also a commonly used fixing method. However, due to the fluidity of the adhesive and the difference in the amount of adhesive injected, when the cooktop glass of the built-in cooktop is bonded to the frame, there are two main problems. First, adhesive overflow is likely to occur, causing the adhesive to overflow onto the bonding surface. Second, it is difficult to ensure the uniformity of the bonding surface during the extrusion process, which can easily lead to large deviations in the thickness of the adhesive layer.

[0068] Please refer to Figure 5As shown, in some embodiments, the bottom surface of the fixed bracket 12 is provided with at least two support portions 122 of the same height. The bottom surface of the cooktop glass is in contact with each support portion 122, and an adhesive cavity 123 is formed between two adjacent support portions 122. There is a gap between the adhesive cavity 123 and the bottom surface of the cooktop glass 20. Specifically, each support portion 122 is arranged along the length direction of the splicing segment 10a, and each support portion 122 is arranged parallel to the inner and outer directions of the cooktop groove 110.

[0069] The cooktop glass 20 is supported by the support part 122, so that a cavity 123 for containing adhesive is formed between adjacent support parts 122. On the one hand, the support part 122 can block the adhesive in the cavity 123 to prevent the adhesive from overflowing. On the other hand, the cooktop glass 20 comes into contact with the support part 122 first when the adhesive is applied. Therefore, the height of the cavity 123 is the thickness of the adhesive layer after the adhesive has cured. Since the height of the support parts 122 is the same, the height of each position of the cavity 123 is the same, so that the adhesive surface is uniform and the thickness deviation of the adhesive surface is relatively small.

[0070] In some embodiments, the support portion 122 protrudes upward from the bottom surface of the fixed bracket 12, and a cavity 123 is formed between the support portion 122 and the bottom surface of the fixed bracket 12; or

[0071] The adhesive cavity 123 is recessed downwards into the bottom surface of the fixing bracket 12, and the bottom surfaces of the fixing bracket 12 on both sides of the adhesive cavity 123 form support parts 122; or

[0072] The support portion 122 protrudes upward from the bottom surface of the fixed bracket 12, and the bottom surface of the fixed bracket 12 between the support portions 122 is recessed downward to form a cavity 123 for receiving adhesive.

[0073] Of course, the support part 122 and the glue-containing cavity 123 can also be other structures, as long as the support part 122 has the same height and can support the cooktop glass 20, and the glue-containing cavity 123 is located between the support parts 122 and can contain the glue. This application will not give examples of each.

[0074] Please refer to Figure 5 As shown, in some embodiments, at least one adhesive guide groove 124 is formed on the bottom wall of the adhesive cavity 123 along the circumferential direction of the stove slot 110. It is easy to understand that if the amount of adhesive injected is too small, the adhesive will not be able to completely fill the adhesive cavity 123, resulting in a region with insufficient adhesive in the adhesive layer, while if the amount of adhesive injected is too large, the adhesive will overflow.

[0075] By opening the glue guide groove 124, on the one hand, glue with a volume greater than that of the glue container 123 can be filled into the glue guide groove 124, ensuring that the glue container 123 is completely filled with glue while avoiding glue overflow. On the other hand, when the glue in the glue container 123 is squeezed by the cooktop glass 20, the excess glue can be filled into the glue guide groove 124 and quickly replenish the insufficient glue area along the glue guide groove 124, thereby forming a relatively uniform glue layer in the glue container 123.

[0076] Specifically, the bottom wall of the adhesive cavity 123 is provided with an adhesive guide groove 124 on each of the inner and outer sides of the support portion 122.

[0077] More specifically, both guide grooves 124 are located at the end of the adhesive surface, adjacent to the support portion 122.

[0078] In some embodiments, S1 = (0.7~0.9)S2, where S1 is the cross-sectional area of ​​the adhesive cavity 123 and S2 is the sum of the cross-sectional areas of the adhesive cavity 123 and the adhesive guide groove 124 inside the adhesive cavity 123.

[0079] If the above ratio is too small, the cross-sectional area of ​​the adhesive guide groove 124 will be too large relative to the adhesive cavity 123. There are two possibilities: the cross-sectional area of ​​the adhesive cavity 123 is too small and the cross-sectional area of ​​the adhesive guide groove 124 is too large. The former may affect the thickness of the adhesive layer and the strength of the adhesive bond, while the latter may affect the adhesive guiding speed of the adhesive guide groove 124, resulting in the inability to replenish the insufficient adhesive area in time.

[0080] If the above ratio is too large, the cross-sectional area of ​​the glue guide groove 124 will be too small relative to the glue container 123. There are two possibilities: the cross-sectional area of ​​the glue container 123 is large and the cross-sectional area of ​​the glue guide groove 124 is small. The former requires too much glue and the material cost is high, while the latter has a relatively poor anti-overflow effect and requires higher precision in the amount of glue injected.

[0081] In addition, the total volume of the glue-containing cavity 123 and the glue-guiding groove 124 is V1, and the total glue-injection volume during glue injection is V2 (which can be controlled by selecting a suitable gating head size and corresponding glue injection process parameters). V2 = (0.7~1.1)V1. When the ratio of V2 to V1 is controlled within this range, it can ensure that the glue layer thickness is sufficient and the adhesive is strong, while minimizing the amount of glue overflow, thereby optimizing the glue overflow problem and saving material costs.

[0082] Please refer to Figure 5 As shown, in some embodiments, the bottom surface of the fixed bracket 12 is also provided with a glue storage tank 125 that is also arranged in the circumferential direction along the stove slot 110.

[0083] Specifically, the glue storage tank 125 is fitted into the outermost support part 122.

[0084] The high viscosity and density of the adhesive cause it to be unable to flow smoothly and fill the adhesive cavity 123 instantly when it is squeezed by the cooktop glass 20. Some adhesive will inevitably be squeezed out from the gap between the support part 122 and the cooktop glass 20. Among them, the gap outside the outer support part 122 is directly connected to the outer surface of the cooktop glass 20 and the flat bracket 10 (i.e. the upper surface of the flange 11). If the adhesive overflows to the outer surface, it will greatly affect the appearance of the product.

[0085] In response, this application provides an adhesive storage tank 125 located on the outer side of the outer support 122. The adhesive storage tank 125 can trap overflowing adhesive, thereby completely preventing the adhesive from overflowing upwards along the gap between the flush bracket 10 and the cooktop glass 20 to the exterior surface.

[0086] More specifically, the cross-sectional area of ​​the glue storage tank 125 is larger than that of the glue guiding tank 124. Since the cross-sectional area of ​​the glue storage tank 125 does not need to be considered in relation to the glue guiding efficiency, increasing the cross-sectional area of ​​the glue storage tank 125 can effectively improve the glue spillage prevention capability of the glue storage tank 125.

[0087] Please refer to Figure 2 As shown, in some embodiments, the cooktop structure also includes an elastic bracket 40, one end of which is fixed to the connecting part 13 and the other end is fixed to the cooktop chassis. The design of the elastic bracket 40 retains the rigidity in the connection direction while increasing the elasticity in the assembly direction. While ensuring reliable connection, the elastic bracket 40 can deform as the screws are tightened during assembly to reduce connection stress.

[0088] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the flat bracket 10 includes four splicing segments 10a with the same cross-section. Each connecting part 13 includes a connecting plate 131 and a bolt post 132. The connecting plate 131 is fixed to the fixed bracket 12, and the bolt post 132 is fixed to the outer side of the connecting plate 131. The bolt post 132 has threaded holes 132a at both ends. In one set of splicing segments 10a, the two ends of the connecting plate 131 are provided with through holes 131a.

[0089] If the splicing sections 10a of the long and short strips have different structures, they will inevitably need to be processed using different molds. However, due to limitations in processing precision, the molds cannot achieve absolute consistency in key dimensions, which can easily lead to splicing steps. In addition, the molds are subject to subsequent wear, resulting in uncontrollable dimensional deviations and poor consistency.

[0090] In the above embodiments, the cross-sections of each connecting part 13 are the same, so they can be processed from the same mold, ensuring the consistency of the splicing section 10a and effectively solving the above problems.

[0091] In some embodiments, the lower side of the bolt post 132 has an opening.

[0092] Please refer to Figure 6 As shown, in some embodiments, two adjacent splicing segments 10a are spliced ​​at an angle at the corner of the flat bracket 10, and the corner tip of the splicing segment 10a is rounded so that the corner tip of the two splicing segments 10a and the splicing position of the corner tip of the two splicing segments 10a are both obtuse angles or rounded corners, thereby preventing the corner tip from hurting the hand, and also weakening the impact caused by assembly misalignment.

[0093] The aforementioned rounded corners can be either arc corners or polygonal angles formed by multiple straight lines; this application does not impose further limitations on them.

[0094] Preferably, the bevel angles of two adjacent splicing segments 10a are both 45°, in order to further improve the splicing integrity and overall aesthetics.

[0095] Please combine Figure 7 as well as Figure 8 As shown, the limiting bolt 14 is set in the horizontal direction, and two adjacent flanges 11 are flush and fit together, and the projections of their fitting positions in the vertical direction at least partially overlap. By limiting the overlap of the projections of the fitting positions of two adjacent flanges 11 in the vertical direction at least partially, when the limiting bolt 14 is tightened, the overlapping portion of the projections of the two flanges 11 has a tightening tendency under the action of the limiting bolt 14, thereby improving the gap and step problem between them.

[0096] Specifically, during the assembly process, when the limiting bolt 14 is tightened, the limiting bolt 14 tends to drive the splicing segment 10a where the second connecting part 13b is located to rotate relative to the other splicing segment 10a. However, since the projections of the flanges 11 of the two splicing segments 10a in the vertical direction at least partially overlap, the two splicing segments 10a cannot rotate relative to each other. Tightening the bolt will cause the two flanges 11 to be further squeezed and pressed together, thereby improving the gap and step problem between the two while completing the fastening between the two splicing segments 10a.

[0097] In some embodiments, the mating surface between the two flanges 11 can be a sloped surface or a stepped surface.

[0098] If the mating surface is a slope, the slope can serve as a limit and guide, so that when the two flanges 11 are subjected to the torsional force generated by the tightening of the limit bolts 14, a tightening tendency is generated between the two mating slopes, thereby alleviating the gap and step problems.

[0099] In some embodiments, the inclined surface can be a plane, a curved surface, or a surface formed by connecting and combining multiple surfaces, as long as it has the tendency to drive the two mating surfaces to move closer together when subjected to a torsional force that brings them closer together. This application will not provide specific examples of these.

[0100] It should be noted that the limiting effect of the inclined plane in the vertical direction relies on the friction between the two mating surfaces, so the limiting effect is limited and the improvement effect on the step problem is relatively poor.

[0101] If the mating surface is a stepped surface, it can limit the relative displacement of the two flanges 11 in the vertical direction after they come together, thereby ensuring that the upper surface of the flanges 11 is flush and effectively solving the step problem.

[0102] Please combine Figure 9 , Figure 10 as well as Figure 11 As shown, a second aspect of this application provides a method for manufacturing a cooktop, used to manufacture the aforementioned cooktop structure, comprising the steps of:

[0103] S100. Two adjacent splicing segments form a group, and limiting components are installed in the corresponding through holes and fixing holes of each group of two splicing segments for pre-limiting;

[0104] S200. Open the moving plate of the assembly fixture and install each set of splicing sections after pre-limiting onto the moving plate and the fixed plate;

[0105] S300. Apply adhesive to the bottom surface of the fixing bracket along each splicing section, and place the cooktop glass on the bottom surface of the fixing bracket;

[0106] S400. The moving plate of the clamping assembly fixture presses against each splicing segment to complete the splicing;

[0107] S500. After the adhesive has cured, remove the cooktop structure and install the limiting components into the remaining corresponding through holes and fixing holes.

[0108] Specifically, the assembly fixture includes a base plate 210, a fixed plate 220, a movable plate 230, and a fixture 240. A limiting groove 211 is provided on the upper surface of the base plate 210. The length and width of the limiting groove 211 are greater than the embedded flat bracket 10. The fixed plate 220 and the movable plate 230 are both L-shaped. The fixed plate 220 is fixed in the limiting groove 211, and the movable plate 230 is slidably connected in the limiting groove 211. Multiple fixtures 240 are fixed on the upper surface of the base plate 210 for pushing and pressing the movable plate 230.

[0109] A third aspect of this application provides a cooktop including the aforementioned cooktop structure.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
