The cover body 21 is provided with a hollow structure 211, the interface end 42 of the water pipe assembly 4 is correspondingly arranged with the hollow structure 211, the electricity-proof wall cover 2 further comprises a cover body 24 which is detachably connected with the cover body 21 and covers the hollow structure 211, the cover body 24 is provided with a matching hole 241, and the interface end 42 is provided with the matching hole 241 in a penetrating way so as to be convenient for connecting an external pipeline with the pipeline assembly. Therefore, a user can realize the overhaul of the part of the water pipe assembly 4, the interface end 42 of which extends out of the machine body 1, without integrally disassembling the cover body 21, and the water pipe assembly 4 can be opened by disassembling the cover body 24 in the maintenance process, so that the overhaul of the electric water heater 100 is realized, and the maintenance cost is reduced.

A third cavity is defined among the display panel housing 25, the housing body 21 and the machine body 1, a second opening 251 is formed in the display panel housing 25, and the display panel 6 is arranged in the second opening 251 and seals the second opening 251 to display the operation status of the electric water heater 100 outwards.

In some embodiments, the display panel enclosure 25, the enclosure 21, and the spacer 23 are integrated to facilitate installation.

Therefore, the water pipe connector and the electricity-proof wall cover 2 are arranged on the outer side of the bottom of the machine body 1, the control module 3 is arranged on the inner side of the electricity-proof wall cover 2, the whole width of the electric water heater 100 is reduced, the space required by indoor arrangement and installation of the electric water heater 100 is reduced, the electricity-proof wall cover 2 arranged on the outer side of the bottom of the machine body 1 can also leak out of the outer side after the electric water heater 100 is partially or wholly embedded into a ceiling, the arrangement of a waterway is facilitated, and the control module 3 can be maintained only by detaching the electricity-proof wall cover 2 in the maintenance process, so that the maintenance process is simplified, the maintenance cost is reduced, and the use experience of a user is improved.
