Plastic liner assembly for water heater and manufacturing method thereof, water heater

Abstract

The invention discloses a plastic liner assembly for a water heater, a manufacturing method thereof, and a water heater. The manufacturing method of the plastic liner assembly includes the following steps: S1, integrally connecting a plastic pipe seal to one end of a metal water pipe to obtain a water pipe assembly; and S2, connecting the water pipe assembly obtained in step S1 with a plastic inner container, wherein the end of the metal water pipe connected with the plastic pipe seal extends into the plastic inner container, and the The surface of the plastic pipe seal adjacent to the other end of the metal water pipe is connected with the inner wall of the plastic liner. According to the manufacturing method of the plastic liner assembly used for water heaters of the present invention, the manufacturing process is simple, no complicated production process is required, the production process is energy-saving and environmentally friendly, and the production yield and qualified rate are high. In addition, by first integrating the metal water pipe with the plastic pipe seal, it is beneficial to integrate the water pipe assembly with the plastic liner without delamination and water leakage.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a plastic liner assembly for a water heater, a manufacturing method thereof, and a water heater. Background technique [0002] The inner container of the traditional water storage type water heater is basically divided into an enamel inner container, a stainless steel inner container and a plastic inner container. The enamel liner is smeared on the metal steel plate by enamel paste or enamel powder by paddle rolling or electrostatic spraying, and then sintered and solidified at high temperature. However, due to the production processes such as stamping and welding iron liner, enamel pretreatment, oar coating (powder spraying) and high temperature sintering, the equipment investment is large, the process is complicated, the production energy consumption is high, and the production pollutes the environment. There is a greater chance of bile leakage. [0003] The stainless ste...

AI Technical Summary

Problems solved by technology

However, due to the production processes such as stamping and welding iron liner, enamel pretreatment, oar coating (powder spraying) and high temperature sintering, the equipment investment is large, the process is complicated, the production energy consumption is high, and the production pollutes the environment. There is a higher chance of bile leakage

[0003] The stainless steel liner is mainly made of stainless steel, and then stamped and then welded. However, due to the production processes such as shearing, punching, and rolling, the production process is complicated. Due to the welding process, the weld seam is prone to water leakage.

In addition, due to the high price of stainless steel, the finished product price of the product is relatively high

[0004] Due to defects or deficiencies in the process or materials of the traditional plastic liner, the plastic liner leaks and the cost is high
