Description

Technical Field

[0001] This application relates to the field of gas appliance technology, specifically to the field of arc-shaped shell technology for small-volume gas water heaters. Background Technology

[0002] Currently, most gas water heater panels on the market are made of materials such as stainless steel, tempered glass, and brushed metal. Some high-end products incorporate curved glass and unibody molding processes to enhance the overall quality. Among these, curved structures are gradually becoming an important trend in home appliance design due to their smooth visual effect.

[0003] However, when applying an arc-shaped structure to small-volume gas water heaters, the limited space makes it challenging to achieve an aesthetically pleasing arc shape while ensuring the structural strength and assembly stability of the casing. In particular, the connection methods between the various components of the casing need to consider the assembly deviations and stress changes caused by the arc-shaped structure.

[0004] Therefore, achieving a curved appearance in a small-volume gas water heater while maintaining good structural stability and safety in use has become a problem that needs to be solved. Summary of the Invention

[0005] In response to the aforementioned problems, this application proposes an arc-shaped shell for a small-volume gas water heater, aiming to achieve the arc-shaped shell effect on a small-volume gas water heater through a completely new design of the overall shell and optimization of the connection method between the shell components.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] An arc-shaped housing for a small-volume gas water heater includes a bottom shell, a front shell detachably connected to the bottom shell, and an arc-shaped panel attached to the front shell.

[0008] The face shell has a hollow structure and has arc-shaped mounting surfaces at least on its left and right or top and bottom ends. The rear end of the face shell has a first insert that can be detachably connected to the bottom shell through fasteners and a second insert that is positioned and connected to the bottom shell.

[0009] The bottom shell is provided with a slot into which the second insert can be inserted. The slot is located at the folded edge of the bottom shell, and the folded edge is provided with an inwardly recessed reinforcing rib at the slot position.

[0010] Thus, the shell adopts a hollow structure and has arc-shaped mounting surfaces at its left, right or top and bottom ends, which can realize the installation of arc-shaped panels while reducing the weight of the overall shell and reducing the stress on the connection strength.

[0011] Meanwhile, the rear end of the front shell is equipped with a first insert and a second insert, which are used to achieve a stable connection with the bottom shell through fasteners and to achieve assembly positioning through the slot structure, respectively. Reinforcing ribs with inward indentation are provided at the corresponding slot positions on the bottom shell, thereby effectively enhancing the local structural strength, preventing deformation or damage caused by uneven stress during assembly, improving the overall structural stability of the unit, and achieving the arc-shaped shell effect on a small-volume gas water heater.

[0012] In some possible implementations, the first insert is disposed at the upper and lower ends of the faceplate.

[0013] In some possible implementations, the second insert is disposed at the left and right ends of the front shell, and the slot is disposed at the left and right ends of the bottom shell.

[0014] In some possible implementations, the second insert and slot are provided in three at each of the left and right ends, and are evenly arranged from top to bottom.

[0015] In some possible implementations, the system also includes inwardly recessed ribs on the left and right sides of the bottom shell, the ribs being positioned corresponding to the slots.

[0016] In some possible implementations, the bottom shell includes a first frame and a second frame that can be spliced ​​together on the left and right sides, as well as a back plate.

[0017] In some possible implementations, the first frame and the second frame form an inwardly recessed seam at the joint.

[0018] In some possible implementations, a reinforcing sleeve is also included, which spans the first and second frames and covers the seam.

[0019] In some possible implementations, the reinforcing sleeve is fitted to the folded edge of the bottom shell. 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] Please refer to Figure 1 and Figure 2 This application describes a small-volume gas water heater with an arc-shaped casing, comprising a bottom shell 1, a front shell 2 detachably connected to the bottom shell 1, and an arc-shaped panel 3 attached to the front shell 2. The bottom shell 1 and front shell 2 are the outer casing components of the gas water heater, primarily manufactured from sheet metal such as cold-rolled steel. The arc-shaped panel 3 is an exterior component, and can be made of materials with good aesthetic appeal, such as stainless steel, tempered glass, brushed metal, or color-coated steel. Its shape is an arc-shaped structure either vertically or horizontally, and it can also be designed with arcs on all four sides. It can be fixed by strong adhesive or, for metal panels, by welding or clips; no specific limitations are made. Figure 3 and Figure 4 This is a schematic diagram when a left-right arc structure is used. In this embodiment, a top-bottom arc structure is mainly used as an example for illustration.

[0032] At this point, the faceplate 2 has a hollow structure, and as described above, it has arc-shaped mounting surfaces 21 at least on its left and right or top and bottom ends. In this way, the hollow structure of the faceplate 2 allows for the installation of the arc-shaped panel 3 while reducing the overall weight of the faceplate 2 and reducing the stress on the connection strength.

[0033] For further details, please refer to... Figure 5 The rear end of the front shell 2 is provided with a first insert 22 that can be detachably connected to the bottom shell 1 via fasteners, and a second insert 23 that is positioned with the bottom shell 1. The fasteners described above can be bolts, screws, etc., which can pass through the bottom shell 1 to tighten the first insert 22. Preferably, the first insert 22 is provided at both the upper and lower ends of the front shell 2, with two inserts at each end.

[0034] Furthermore, please refer to the references. Figure 5 and Figure 6 , Figure 7 Corresponding to the second insert 23, the bottom shell 1 is provided with a slot 11 into which the second insert 23 can be inserted. The slot 11 is located at the folded edge 100 of the bottom shell 1, and the folded edge 100 has an inwardly recessed reinforcing rib 12 at the slot 11 position. The folded edge 100 described above is a conventional technique in the sheet metal processing field. The same folded edge 100 is also provided on the front shell 2, which will not be described in detail. In this embodiment, the folded edge 100 will be represented by the same graphic reference numerals. In fact, the first insert 22 and the second insert 23 are also bent.

[0035] Specifically, the second insert 23 is disposed at both ends of the front shell 2, and the corresponding slot 11 is also disposed at both ends of the bottom shell 1. Preferably, there are three second inserts 23 and three slots 11 at each end, evenly distributed from top to bottom. To further strengthen the position of the slot 11, inwardly recessed ribs 13 are provided on the left and right sides of the bottom shell 1, and the ribs 13 are disposed at positions corresponding to the slots 11.

[0036] Thus, the rear end of the front shell 2 is provided with a first insert 22 and a second insert 23, which are used to achieve a stable connection with the bottom shell 1 through fasteners and to achieve assembly positioning through the slot 11 structure, respectively. Reinforcing ribs 12 are provided inwardly at the corresponding slot 11 positions on the bottom shell 1, thereby effectively enhancing the local structural strength, preventing deformation or damage caused by uneven stress during assembly, improving the overall structural stability of the unit, and achieving the arc-shaped shell effect on a small-volume gas water heater.

[0037] Therefore, when achieving a curved shell effect on a small-volume gas water heater, the actual bottom shell 1 has a relatively large ratio in front-to-back depth compared to its left-to-right width, making one-piece machining difficult. Please refer to [the relevant documentation / reference needed]. Figure 8 The bottom shell 1 can solve the problem of difficult one-time processing through an assembly structure, which includes a first frame 41 and a second frame 42 that can be spliced ​​left and right, as well as a back plate 43. Specifically, after the first frame 41 and the second frame 42 are spliced ​​left and right, inwardly recessed splicing seams 14 will be formed at their upper and lower ends. These seams are formed by overlapping the splicing ends during the splicing process. Then, the back plate 43 is spliced ​​and fastened to its rear end.

[0038] Please refer to the reference. Figure 6 and Figure 8 Furthermore, it also includes a reinforcing sleeve 5 that spans the first frame 41 and the second frame 42 after splicing. The reinforcing sleeve 5 covers the splicing seam 14, and one is provided at the top and one at the bottom. Preferably, the reinforcing sleeve 5 is attached to the folded edge 100 of the bottom shell 1, that is, the reinforcing sleeve 5 forms a reinforcement of the folded edge 100 with the front shell 2 at the front end, further improving the connection strength.

[0039] As stated above, this case protects the arc-shaped casing of a small-volume gas water heater, 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.
