[0002] Currently, the housings used in household gas-fired instantaneous water heaters can be installed with different structural bottom shells and panels according to different design structures. To reduce costs, the existing housings have removed the aluminum frame from the housing panels. However, when reducing costs, the assembly tolerances of the entire machine cannot be guaranteed. This results in large assembly gaps between the panel and the bottom shell, large height differences between the panel and the bottom shell, misalignment, and uneven matching. In order to ensure the neatness and consistency of the panel and the bottom shell, the panel and the bottom shell need to be optimized.

[0003] According to the in-depth improvement of the application of existing technologies, the panel is generally used as an integral bracket to cooperate with the bottom shell for installation. However, the existing panels are generally installed using a single bracket or a connected bracket. When such an installation structure is applied to the installation of the whole machine, its installation effect is not very good. There are problems such as large assembly gap between the panel and the bottom shell, large height difference between the panel and the bottom shell, and misalignment, which cannot guarantee the consistency of the installation and appearance of the whole machine.

[0004] Therefore, further improvements are necessary. Utility Model Content
