Description

Technical Field

[0001] The invention relates to the technical field of gas water heaters, and in particular to a bottom shell structure of a gas water heater shell. Background Art

[0002] The shell of the gas water heater includes a bottom shell and a front shell. The bottom shell is used to fix the burner, heat exchanger and various control components, etc., and serves as a bracket for fixing the wall; the front shell plays the role of windproof, dustproof, observation of combustion status and printing various signs. The bottom shell of the gas water heater includes a bottom plate, a side plate is arranged on the left and right sides of the bottom plate, an upper baffle is arranged above the bottom plate, and a lower baffle is arranged below the bottom plate. The upper baffle is located above the two side plates, and the lower baffle is located below the two side plates. The bottom plate, the two side plates, the upper baffle and the lower baffle together form a box structure with a front opening, and the front shell is used to cover the front opening of the bottom shell.

[0003] During the processing and manufacturing of the bottom shell, the two side panels on the bottom plate are usually formed by bending the two side edges of the bottom plate, that is, the bottom plate and the two side panels are formed as one piece, while the upper baffle plate and the lower baffle plate are welded to the bottom plate separately; compared with the method of forming the upper baffle plate and the lower baffle plate by bending, separate welding can reduce the generation of scraps and is conducive to saving materials.

[0004] The disadvantage of welding the upper baffle and the lower baffle directly to the bottom plate is that, first, the size of the upper baffle and the lower baffle needs to be controlled. If the size of the upper baffle and the lower baffle is too large, it will cause obvious defects in the shape of the bottom shell. If the size of the upper baffle and the lower baffle is too small, the upper and lower openings of the bottom shell cannot be closed. Either the two side plates need to be slightly bent so that the upper baffle and the lower baffle can be welded to the side plates on both sides, but this will increase the difficulty of welding and make welding inconvenient. It may even cause unsightly deformation of the shape of both sides of the bottom shell, affecting the processing quality. Secondly, when welding, it is necessary to manually hold the upper baffle and the lower baffle, align the upper baffle and the lower baffle with the corresponding openings of the bottom shell, and then weld. If they are not aligned, the welding quality of the bottom shell will be easily reduced. In short, the processing quality of the bottom shell is difficult to guarantee. Summary of the invention

[0005] The object of the present invention is to provide a bottom shell structure of a gas water heater shell, aiming to improve the problem in the prior art that the welding processing quality of the bottom shell is difficult to ensure.
