Problems solved by technology

This structure has the following disadvantages: the welding process is complicated, and the operability in the production process is not good; in the enamel process, because the connecting pipe is not flat, it will cause defects such as uneven coating of the enamel layer and lack of porcelain on the connecting pipe, thus In the future, the carbon steel liner will be corroded and other consequences will be caused; the enamel liner needs to be welded and installed, and the freedom of combination is not high.

Abstract

The present invention discloses an improved electric water heater with enamel inner container, it includes enamel inner container and electric heating pipe, its characteristics are: the ends of said enamel inner container is equipped with flange mouth; the water inlet and water outlet of enamel inner container are installed on the flange mouth. The present invention uses two or more enamel inner containers which are in parallel connection to form a integral enamel inner container, it not only reduces the production costs of enamel inner container, but also overcomes the technical difficulties of enamel inner container is not suitable for producing electric heater in flat appearance. The invention has advantage of simple technology, compact size, uniform mixing of hot and cold water and high rate of hot water discharging, it applies to horizontal or vertical electric heater in flat appearance.

Description

Technical field [0001] The invention relates to an inner container for electric water heaters, in particular to an enamel inner container for electric water heaters, which can be applied to horizontal or vertical electric water heaters. Background technique [0002] From the point of view of materials, the existing inner tank of electric water heater needs high temperature resistance and water corrosion resistance when used, and it is usually made of stainless steel. As the price of stainless steel continues to rise, the production cost of the inner tank of the electric water heater is high, and the price of the electric water heater is also rising. In order to reduce the production cost of electric water heaters, manufacturers began to use enamel materials with a price of only one-eighth to one-fourth of stainless steel to make the inner tank; however, these positions are easily damaged when holes are made on the enamel inner tank or welded. The enamel surface is damaged and the...
