Abstract
A combined type heater of an electric water heater comprises a electric heating body, a flange for fixing the heating body and water storage tank. The water storage tank comprises an inner container and a metal shell. The inner container is integrally formed through non-metal high-temperature-resistant material. An opening is formed at one end of the inner container. A cylindrical flanging is formed at the opening of the inner container. The metal shell wraps the inner container. The cylindrical flanging of the inner container extends out of the opening at the end of the metal shell. The flange is fitted to and in liquid-gas seal with the end face of the cylindrical flanging. The flange is fixedly connected with the metal shell. A cold water inlet pipe, a hot water outlet pipe and a blow-off pipe are arranged on the flange and communicated with the inner cavity of the inner container. By the structure, the combined type heater has the advantages that due to the fact that the inner container is integrally formed through non-metal high-temperature-resistant material, free of welds, high in corrosion resistance, free of water leaking, low in heat conducting coefficient, good in hot water thermal insulation effect, slow in heat dissipation and energy saving; the metal shell wrapping the inner container is high in strength and long in service life.
