Abstract

A water storage tank of a water heater comprises a main body (1) and a fastening set (2, 3, 4, 5). The main body may comprise two horizontally arranged half-casing (11, 12) fixed with each other, and an accommodation space capable of storing water is enclosed therein. The fastening set comprises two fastening mechanisms accommodated in the accommodation space. The two fastening mechanisms each are fixedly disposed in one of the half-casings. The two fastening mechanisms are engaged with each other, so that the two half-casings cannot be separated in a horizontal direction. Therefore, the water storage tank of a water heater has high structure strength, and can resist deformation incurred by thermal expansion, so as to prevent the water storage tank from warping arbitrarily under the effect of the temperature, thereby improving the durability and service life thereof.
