Water storage type water heater

Abstract

The invention relates to a water storage type water heater, and belongs to the technical field of water heaters. The water heater comprises an outer shell, an inner container and a thermal insulatinglayer; and the outer shell comprises a straight section, and the straight section is an integrated type cylinder body which is molded by extrusion. According to the water storage type water heater, the cylinder body of the outer shell of the water heater is produced and manufactured by an extrusion molding method, the molding procedure of the outer shell of the water heater is simple, the production efficiency is improved, and the conditions that in the prior art, the quality control difficulty of the cylinder body of the outer shell is high, the refining level of a product is low and the rejection rate is high due to the fact that the outer shell is molded through a plurality of working procedures are avoided; in addition, extrusion molding is adopted, the straight section can be subjected to extrusion molding into a plurality of shapes according to product requirements, and the appearance of the outer shell is enriched.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a storage water heater. Background technique [0002] Existing cylindrical water heaters are generally manufactured by sheet metal technology. The sheet metal technology is processed into a cylindrical shape, and then the appearance is treated and protected by spraying, spraying and other processes. The process is complicated and requires a lot of The water, gas and electricity required by the factory have high requirements on the capacity of the factory equipment, and special powder spraying equipment and workshops are required. The whole process of production includes multiple processes such as degreasing and powder spraying, which reduces the production efficiency; and the product shape is relatively single. The plasticity is poor, and basically only the shell of the circular structure can be produced. In addition, the shell is pressed or welded, and there are joint lin...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to propose a water storage water heater, which can solve the technical problems in the prior art that the production efficiency is reduced due to the complex forming process of the shell and the single shape of the shell is caused by the use of the existing forming process.
