The top of the front shell 310 is provided with a first notch 311, the top of the rear shell 320 is provided with a second notch 323, and after the front shell 310 is connected with the rear shell 320, the first notch 313 and the second notch 323 are just butted to form a maintenance opening 330.
In this embodiment, a foaming chamber 500 is formed between the outer shell 300, the bottom end surface of the thermal insulation member 100, and the inner container 200 located below the thermal insulation member 100.
In the prior art, the foaming cavity is usually formed by a gap between the shell and the inner container, the foaming volume is large, the foaming pressure is large, the foaming material is easy to overflow in the foaming process, and parts such as the inner container are easy to shift due to the foaming pressure, so that the fine stability of a product after processing and forming is influenced, and the subsequent parts are inconvenient to position and install.
In the application, through the arrangement of the heat preservation part 100, the foaming cavity 500 is formed by the shell 300, the bottom end face of the heat preservation part 100 and the gap between the inner containers 200 below the heat preservation part 100, the foaming volume is small, the foaming pressure is small, the problems that parts such as foaming material flash, the inner containers and the like are subjected to foaming pressure to generate position deviation and the like can be effectively avoided, the fine stability of products is improved, and the positioning and the installation of subsequent products are facilitated.
The heat insulation member 100 has a heat insulation performance while forming the foaming cavity, and is also helpful for improving the heat insulation performance of the electric water heater.
The upper part of the inner container 200 is embedded into the heat insulation piece 100, so that the heat insulation piece 100 does not occupy more space in the shell 300, the compact design of the components in the shell 300 is facilitated, and the miniaturization design purpose of the product is facilitated; meanwhile, the heat preservation member 100 also plays a role in positioning and supporting the inner container 200, and further prevents the inner container 200 from deviating in the foaming process.
In the embodiment, the design that the heat insulation piece 100 is arranged in the shell 300 and on the inner container 200 subverts the conventional design idea of the existing electric water heater, and improves the refinement stability of product processing and forming from the perspective of reducing the foaming volume and the foaming pressure; meanwhile, the advantages of heat preservation, compact design and the like are considered.
By utilizing the easy processability of the heat preservation piece 100, the heat preservation piece 100 is easy to be designed differently aiming at shells and inner containers with different sizes and shapes, so that the heat preservation piece 100 has stronger applicability and can be applied to electric water heaters of different types.
In actual processing, it is difficult to ensure absolute seamless installation between the heat preservation member 100 and the inner container 200 and between the heat preservation member 100 and the outer container 300, so even if a small amount of foaming material overflows, the foaming material flows for a short distance along the heat preservation member 100 and then is cooled and shaped, and due to the positioning and supporting effect of the heat preservation member 100 on the inner container 200, the overflow of the small amount of foaming material cannot influence the position deviation of the inner container 200, and on the contrary, the matching stability between the heat preservation member 100 and the outer container 300 as well as the inner container 200 can be further improved after the small amount of foaming material is cooled and shaped.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
