Abstract

An electric water heater structure includes a casing, a tank and a heater. The inner tube is welded with a first fixed plate as a load-bearing strength support for the hook, and can be matched with a hanging plate fixed to the wall to be a hanging structure. The inner tank is further provided with a second fixing plate and an adjusting seat, which is located below the first fixing plate and the hanging hook, so that the electric water heater structure can be vertically fitted to the wall surface. This creation mainly adds a heat-insulating gasket (low-conducting material) to the inner fixed plate and the second fixed plate, and is placed in the outer casing. After filling the insulating layer, it can be assembled after being foamed. The process is blocked by a low conductivity material to improve the heat transfer path of the suspended structure.
