Abstract
The invention discloses an inner cylinder of an electric water heater and a manufacturing method thereof. The inner cylinder of the electric water heater comprises a shell and a Teflon coating layer, wherein the Teflon coating layer is arranged on the inner surface of the shell. According to the inner cylinder of the electric water heater disclosed by the invention, since the non-viscous Teflon coating layer is formed on the inner surface of the inner cylinder, water scales are not produced on the inner surface of the inner cylinder and the water in the inner cylinder is cleaner and more hygienic. Even though the electric water heater burns dry, no electric shock occurs and jeopardizes the safety of people and the reliability of the electric water heater is improved. Moreover, the Teflon coating layer can effectively prevent the metal material of the inner cylinder from being corroded and damaged due to electrochemical reaction and can prevent the inner cylinder from being subjected to chemical corrosion of any type, and thus the service life of the inner cylinder is longer. When the Teflon coating layer is formed, the sintering temperature is lower and the energy consumption during production is reduced.
