AI Technical Summary

Technical Problem

The existing water heater exterior case design, where the top and side panels are integrally formed with inwardly bent rear ends, faces interference issues during back panel installation, leading to plastic deformation or exposure of the back panel edges.

Method used

A housing design with a box-shaped structure featuring integrally formed top and side panels, including inwardly bent pieces for the front, rear, and lower ends, allowing the back panel to be properly aligned by spreading the side panels, while minimizing exposure and reducing parts.

Benefits of technology

The solution reduces plastic deformation and ensures easy installation of the back panel by aligning the back panel edges with inwardly bent pieces, maintaining structural integrity and ease of assembly.

Abstract

To provide a technology which can achieve both a reduction in number of part items and the suppression of exposure of an end part of a back plate part and can easily attach the back plate part, in a box body part constituting a water heater.SOLUTION: A box body part 2 of a water heater 1 comprises: a box-shaped box body main body 2B in which an opening part 2W is formed at a front end side; and a front panel 2A fixed to the box body main body 2B so as to block the opening 2W. At a peripheral edge part of a block plate part 30 of the box body main body 2B, a first notch 110 arranged at a lower position rather than an upper end part 33 and the other side in a right-left direction rather than a first side part 31 is formed between an upper end of the first side part 31 and one end of the upper end part 33 in the right-left direction. A second notch 120 arranged at the lower position rather than the upper end part 33 and one side in the right-left direction rather than a second side part 32 is formed between an upper end of the second side part 32 and the other end of the upper end part 33 in the right-left direction.SELECTED DRAWING: Figure 3
