Description

Technical Field

[0001] This utility model belongs to the technical field of connecting components for integrated stoves, specifically relating to a positioning connector that is simple in structure, easy to use, and has a stable connection, and an integrated stove. Background Technology

[0002] The upper-level control unit (part of the integrated stove) typically includes a smoke collection hood and a smoke baffle at its top, which blocks cooking fumes and guides them into the smoke collection chamber. However, due to the protruding installation of the smoke baffle, the connection area between it and the side column is extremely small, leading to significant drawbacks in traditional connection methods: such as difficulty in simultaneously achieving precise positioning and welding / fastening operations in a narrow space, easily resulting in misalignment; also, when the non-connecting end of the smoke baffle is subjected to external force, there is a lack of an effective load-bearing structure to distribute the load, leading to weld failure or stress concentration in the connectors; there are also problems such as poor connection stability, forcing frequent maintenance. Utility Model Content

[0003] To address the aforementioned technical problems, this application further improves the structure of the mounting connector for the smoke baffle on the integrated stove, aiming to obtain a smoke baffle with a stable mounting structure. One objective of this utility model is to provide a positioning connector that integrates welding and insertion; another objective is to provide a corresponding integrated stove.

[0010] In a further embodiment, a third connecting portion is provided between the bent connecting surface and the second connecting portion, the third connecting portion having an extension structure for attaching the second connecting portion to the aforementioned side column.

[0011] In some embodiments, the first connecting portion, the second connecting portion, and the third connecting portion are integrally formed.

[0012] In some embodiments, the side column connecting portion is a through hole for connection.

[0013] An integrated cooktop includes a smoke collection hood, a smoke baffle, and side columns disposed at both ends of the smoke collection hood. The smoke baffle is connected to the side columns via a positioning connector as described in any of the above technical solutions.

[0014] In summary, the technical solution described in this utility model has the following main beneficial effects: Compared with the prior art, in the present invention, the positioning is first achieved by inserting the positioning hole into the side column positioning hole.

Detailed Implementation

[0020] The present invention will be further explained in conjunction with the embodiments: The core technical problem faced by the technical solution of this application embodiment stems from the inventor's accurate understanding of the prior art. Therefore, how to make the installation structure of the smoke baffle more stable and the installation operation more convenient is a technical problem that the inventor urgently needs to solve.

[0021] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this utility model. All technical solutions that can be reasonably expected by those skilled in the art based on the technical concepts provided / proved by the embodiments should be covered within the scope of protection of the claims of this utility model.

[0022] The specific implementation examples are detailed below: Please refer to the attached document. Figures 2-5This embodiment discloses a positioning connector 3, which adopts an integrated welding and plug-in structure, mainly including a first connecting part 3.1 and a second connecting part 3.2. The first connecting part 3.1 is provided with a first welding surface 3.11 and a plug-in positioning hole 3.12. During actual installation, the first welding surface 3.11 is directly welded to the welding flange 1.33 on the side of the smoke baffle 1, while the plug-in positioning hole 3.12 is plugged into the side column positioning hole 1.32 on the same side of the smoke baffle 1 to form preliminary positioning. Simultaneously, the second connecting part 3.2 is designed with a side column connecting part 3.21 for final connection with the side columns b at both ends of the smoke hood a. Thus, the initial positioning pin insertion through the plug-in positioning hole 3.12 ensures the alignment accuracy during welding and connection. Combined with the welding of the first welding surface 3.11 and the connection of the side column connecting part 3.21, the entire installation process can be completed without complex tools, making the operation simple and efficient. This design enables convenient installation and operation, and provides comprehensive connection areas. Furthermore, due to the simple structure of the positioning connector 3, it can be produced with only basic stamping and welding processes, significantly reducing production costs.

[0023] In a further embodiment, the first connecting portion 3.1 forms a bent connecting surface 3.13 in the area where the insertion positioning hole 3.12 points towards the second connecting portion 3.2. This bent connecting surface 3.13 is formed by bending at an angle towards the interior of the host computer, extending partially in the direction of gravity and supporting the weight of the smoke baffle 1, thus forming a load-bearing structure. For example, after the smoke baffle 1 is installed, the bent connecting surface 3.13 can effectively distribute the load under gravity. Thus, the bent connecting surface 3.13 optimizes the force distribution through its bending direction, transferring part of the weight of the smoke baffle 1 to the connector, thereby reducing the load on the structure of the smoke baffle 1 itself and avoiding deformation or damage caused by concentrated force.

[0024] In a preferred embodiment, the welding surface of the first welded portion 3.11 is designed to be completely fitted with the welding flange 1.33 of the smoke baffle 1. Specifically, the welding surface is matched to the contour of the welding flange 1.33 through a bending or forming process to ensure seamless alignment of the contact surfaces, so as to form a uniform weld during welding. In this way, the fitted welding surfaces can generate a larger contact area and a deeper penetration during welding, forming a stronger weld; at the same time, since the welding surface is usually curved, the curved weld structure can effectively disperse and resist external force impacts from different directions, such as vibration or lateral tension, thereby making the welded connection more robust and reliable, and reducing the risk of loosening.

[0025] In a further embodiment, a bent auxiliary welding flange 3.14 is provided on the side of the first connecting portion 3.1. This auxiliary welding flange 3.14 is manufactured through an additional bending process and is directly welded to the side column insertion portion 1.5 on the same side as the smoke baffle 1, forming an additional connection point. For example, during installation, the auxiliary welding flange 3.14 can be aligned with the corresponding area of ​​the side column insertion portion 1.5 and then spot-welded. In this way, the added auxiliary welding flange 3.14 increases the number and distribution range of welding points, improves the overall welding strength, and prevents the connector from shifting or falling off under stress.

[0026] In a further embodiment, the auxiliary welding flange 3.14 is positioned below the bent connecting surface 3.13. During actual installation, the auxiliary welding flange 3.14 and the bent connecting surface 3.13 are vertically offset to avoid structural overlap. This firstly simplifies the installation process and facilitates welding tool operation by spatially offsetting the auxiliary welding flange 3.14 from the bent connecting surface 3.13; secondly, when the auxiliary welding flange 3.14 is positioned below, it directly assists the bent connecting surface 3.13 in bearing the weight of the smoke baffle 1, distributing more of the load and enhancing the overall support capacity.

[0027] In some embodiments, the auxiliary welding flange 3.14 is positioned on the side relative to the first welding portion 3.11, i.e., the two are located on different sides of the connector. In the actual structure, the auxiliary welding flange 3.14 and the first welding portion 3.11 do not interfere with each other in the horizontal direction, forming a symmetrical or offset layout. In this way, the auxiliary welding flange 3.14 and the first welding portion 3.11 are spatially offset from each other, which facilitates the welding point operation during installation and avoids conflicts; and the welding positions are distributed on both sides, which can form multi-point constraints, making the positioning connector less likely to move or twist under force, and the connection structure is more stable and reliable.

[0028] In a further embodiment, a third connecting part 3.3 is introduced for the connection between the bent connecting surface 3.13 and the second connecting part 3.2. This third connecting part 3.3 is designed as an extended structure, connecting the bent connecting surface 3.13 and the second connecting part 3.2, for example, by bending or straightening, and attaching the second connecting part 3.2 to the surface of the side column b, ensuring tight contact. Thus, since the first connecting part 3.1 and the second connecting part 3.2 have different functions (one is responsible for connecting the smoke baffle 1, and the other for connecting the side column b), the third connecting part 3.3, as a transition structure, allows the first connecting part 3.1 and the second connecting part 3.2 to each be in their proper positions, avoiding abrupt connections or structural interference; at the same time, it does not hinder the installation process, ensuring a reasonable overall layout.

[0029] In a preferred embodiment, the first connecting part 3.1, the second connecting part 3.2, and the third connecting part 3.3 are manufactured using an integral molding process, for example, by stamping and bending a single piece of metal sheet to form a continuous integral structure. This integral molding eliminates the assembly step, facilitating mass production; simultaneously, the seamless or jointless overall structure can withstand greater external forces, resulting in better overall robustness and reducing the risk of breakage.

[0030] In some embodiments, the side column connector 3.2 is designed as a through hole for connection, such as a circular or square hole, which can be directly fixed to the side column b by bolts or rivets. In this way, the through hole structure simplifies the connection operation, requiring no special tools and only standard fasteners, making the operation convenient; at the same time, the through hole processing cost is low, making it suitable for mass production.
