End cover, inner container assembly and water heater

The embodiment of the invention provides an end cover, an inner container assembly and a water heater, the end cover comprises a body, the body comprises a plurality of arc-shaped branch parts, the arc-shaped branch parts are arranged on the two sides of the longitudinal center line of the body so as to jointly define an inwards-concave space of the body, and the body is an integrally-formed part. By the adoption of the technical scheme, the end cover can solve the technical problems that an enamel layer is not uniform and lacks enamel in the follow-up enamel process due to welding seams of the connecting parts, stress borne by the body is dispersed, stress distribution of the body is improved, and the structural strength of the end cover is improved. 本申请实施例提供一种端盖、内胆组件及热水器，其中，端盖包括本体，本体包括多个弧形分部，多个弧形分部分设于本体的纵向中心线的两侧，以共同限定出本体的内凹空间，其中，本体为一体成型件。通过采用上述技术方案，本申请实施例的端盖可以解决因连接部位的焊缝导致后续搪瓷工序中搪瓷层不均匀、缺瓷的技术问题，并且有利于分散本体所受的应力，改善本体的应力分布，提高端盖的结构强度。
