Abstract
Description
Technical Field
[0001] This utility model relates to the field of water tanks, and in particular to a water tank with a novel welding structure. Background Technology
[0002] In existing technologies, sinks are typically connected by welding the cavity to the panel, with the cavity mounted on the cooktop via the panel. However, due to differences in surface texture between the cavity and the panel, welding results in inconsistent surface textures across the sink, affecting the product's aesthetic harmony. Furthermore, when the cavity incorporates stamped stepped features, this structure can cause significant deformation of the panel's levelness during welding, especially in countertop installations, resulting in a large gap in the center of the panel and noticeably reducing the overall aesthetic appeal of the installed sink.
[0003] Based on the above, the existing water tanks with the new welding structure need further improvement. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water tank with a novel welded structure. By integrally bending an extension along the edge of the tank cavity and placing the panel on the underside of the extension, the load-bearing capacity of the water tank is guaranteed, the overall surface texture of the water tank is kept consistent, and deformation problems caused by the stepped welding of the panel and the tank body are avoided.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water tank with a novel welded structure, comprising a tank body and a panel, wherein the tank body includes a recessed cavity and an extension formed by bending the edge of the tank body, and the panel is disposed on the lower side of the extension and the edge of the extension is flush with the panel.
[0006] This invention features an extension integrally bent along the edge of the sink cavity, with the panel positioned beneath the extension. This design ensures the sink's load-bearing capacity while maintaining a consistent surface texture, and avoids deformation issues caused by the stepped welding of the panel to the sink body. Compared to existing technologies, this novel welded structure enhances the sink's overall aesthetics.
[0007] Preferably, the extension is a plane, and the outer side of the extension is flush with the outer side of the panel to keep the outer side of the sink flat. This makes the outer side of the sink look aesthetically pleasing when using the countertop installation method. When using the in-table or under-table installation method, the gap between the sink and the side mounting surface can be reduced, resulting in a flatter installation.
[0008] Preferably, the extension is designed in a hook shape, and the lower end face of the extension is flush with the lower end face of the panel to keep the water tank mounting surface flat. This ensures that when using the tabletop or center-mounted mounting method, the water tank and the lower mounting surface are aligned and flat, reducing gaps and making the installation more stable.
[0009] Preferably, the outer dimension of the panel is smaller than the outer dimension of the extension, and the inner dimension of the panel is larger than the outer dimension of the cavity, to prevent the panel from being too large and unable to be flush with the outer side of the extension, thus affecting the overall aesthetics of the sink.
[0010] Preferably, the tank body is integrally formed, which makes the connection between the extension and the tank cavity stable, not easy to break, and the risk of the tank cavity falling off is low, thus improving the safety of use.
[0011] Preferably, the extension includes a first contact surface and a second contact surface, the second contact surface being formed by bending the first contact surface downwards; both the first contact surface and the second contact surface are integral structures of the tank body, so that even if the tank adopts a platform mounting structure with the most exposed surface, the surface texture of the tank can be kept consistent, and the overall aesthetics are high.
[0012] Preferably, the upper surface of the panel is in contact with the first contact surface, and the outer surface of the panel is in contact with the second contact surface.
[0013] Preferably, the outer side of the panel is welded to the outer side of the extension.
[0014] Preferably, the lower end face of the panel is welded to the lower end face of the extension. Attached Figure Description

[0024] Example 1
[0025] See Figures 1 to 4 .
[0026] This embodiment discloses a water tank with a novel welded structure, including a tank body 2 and a panel 3. The tank body 2 includes a recessed cavity 21 and an extension 22 formed by bending the edge of the tank body 2. The panel 3 is disposed on the lower side of the extension 22 and the edge of the extension 22 is flush with the panel 3.
[0027] The extension 22 is planar, and its outer surface is flush with the outer surface of the panel 3. This design ensures that the upper surface of the groove 2 and the surface texture of the groove cavity 21 are consistent, making it particularly suitable for center-mounted installations.
[0028] To ensure that the outer side of panel 3 is flush with the outer side of extension 22, the outer dimension of panel 3 is smaller than the outer dimension of extension 22, and the inner dimension of panel 3 is larger than the outer dimension of cavity 21.
[0029] The tank body 2 is integrally formed. Specifically, the tank body 2 adopts an integral stretch forming technology, and its external dimensions are ensured by laser cutting and die stamping. Because the tank body 2 of this solution is integrally formed, the connection between the extension 22 and the tank cavity 21 is stable and not easy to break, thus the risk of the tank cavity 21 falling off is low and the safety of use is high.
[0030] The outer side of the panel 3 is welded to the outer side of the extension 22.
[0031] This invention features an extension 22 integrally bent along the edge of the trough cavity 21, with the panel 3 positioned beneath the extension 22. This design ensures the load-bearing capacity of the water tank while maintaining a consistent surface texture. It also avoids deformation issues caused by welding the panel 3 to the stepped features of the trough body 2. Compared to existing technologies, this invention's novel welding structure enhances the overall aesthetics of the water tank.
[0032] Example 2
[0033] See Figure 1 , Figure 2 , Figure 5 and Figure 6 This embodiment is an improvement on the first embodiment, and the difference between it and the first embodiment is that the shape of the extension 22 is different.
[0034] The extension 22 is designed in a hook shape, and the lower end face of the extension 22 is flush with the lower end face of the panel 3.
[0035] To make the water tank with the new welding structure more suitable for tabletop installation, the extension 22 includes a first contact surface 221 and a second contact surface 222, the second contact surface 222 being formed by bending the first contact surface 221 downward.
[0036] The upper surface of the panel 3 is attached to the first contact surface 221, and the outer surface of the panel 3 is attached to the second contact surface 222. In this design, the panel 3 is flatly attached to both the first contact surface 221 and the second contact surface 222, and the panel 3 provides support for the extension 22, thereby increasing the load-bearing capacity of the groove 2.
[0037] Specifically, the sum of the thicknesses of the first contact surface 221 and the panel 3 is 2-7 mm.
[0038] The lower end face of the panel 3 is welded to the lower end face of the extension 22.
[0039] In this embodiment, the extension 22 makes the surface texture of the upper end face, outer side face and cavity 21 of the groove body 2 consistent, which is especially suitable for tabletop installation.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
