Composite-type inner container and water heater with same

Abstract

The invention discloses a composite-type inner container and a water heater with the same. The composite-type inner container comprises a plastic inner container body, metal water pipes and a glass fiber member, mounting holes are formed at the bottom of the plastic inner container body, one end of each metal water pipe penetrates the corresponding mounting hole to extend into the plastic inner container body, a boss is arranged on each metal water pipe and positioned in the plastic inner container body, and the glass fiber member is wound on the outer surface of the plastic inner container body. By arranging the bosses on the metal water pipes, after the metal water pipes and the plastic inner container body are assembled in place, water in the plastic inner container body can be effectively prevented from flowing out from gaps between the mounting holes and the metal water pipes; by the inner container body made by plastic, the composite-type inner container is enabled to adapt to changes of pressure of the inner container; by wounding the glass fiber member on the outer surface of the plastic inner container body, the composite-type inner container is enabled to be resistant to high pressure, so that using state of the water heater is met better, and service life of the water heater is prolonged.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a composite liner and a water heater with the same. Background technique [0002] The inner container of the traditional water storage water heater is basically divided into an enamel inner container and a stainless steel 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 steel liner is mainly made of stainless steel, and then stamped and welded. Howe...

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
