Abstract
A combined type heater of an electric water heater comprises an electric heating body, a flange for fixing the heating body and a water storage container. The water storage container comprises an inner container and a metal shell. The inner container is integrally made of non-metal high-temperature-resistant materials and an opening is formed in one end of the inner container and provided with a cylindrical flanging. The inner container is coated with the metal shell and the cylindrical flanging of the inner container extends out from an end opening of the metal shell. The flange is attached to the end face of the cylindrical flanging so that the liquid-gas sealing function can be achieved. The flange is fixedly connected with the metal shell. A cold water inlet pipe, a hot water inlet pipe and a sewage discharging pipe are arranged on the flange and communicated with an inner cavity of the inner container. By the adoption of the structure, the inner container is integrally made of the non-metal high-temperature-resistant materials, welding joints are eliminated, the corrosion resistance is high, and water leakage is avoided; the inner container is made of the non-metal materials, so that the heat conductivity coefficient is low, the hot water heat preservation effect is good, heat is dissipated slowly, and energy is saved; the inner container is coated with the metal shell, so that strength is high, and the service life is long.
