Abstract

The utility model relates to a plastics-steel water storage type inner container of an electric water heater. Primarily, a plastic lining corresponding to the shape and the size of the inner surface of the inner container is arranged in a steel electric water heater inner container, the plastic lining covers the inner surface of the steel inner container whole, and the plastic lining is attached to the inner surface of the steel inner container tightly. The lining can be stacked by multiple layers together. The utility model has simple structure, easy process, easy fabrication and low cost, and the utility model can isolate water and the steel inner container, causing the steel inner container to have no corrosion, and the service life of the inner container is prolonged.

Description

Plastic-steel storage-type electric water heater inner bag

Technical field the utility model relates to a kind of electric heater.

The electric heater that background technology is sold in the market, its inner bag has nothing in common with each other, and stainless steel inner container is arranged, and also has the steel inner container inner surface to carry out the various inner bags of surface-treated with enamel, resin and rare earth material.Though they all have certain resistance to corrosion, but still there is shortcoming separately, as the easy fouling of the long-term use of stainless steel inner container, its weld seam also can ftracture because of corrosion, adopt enamel, resin and rare earth material that the inner bag inner surface is handled, complex process not only, and it is different with the steel inner container coefficient of expansion and cause anticorrosive coat be full of cracks or obscission to exist coating, also may be because of the tiny flaw that is produced in the manufacture process, cause corroding in the use afterwards, produce to leak at last, influence water heater service life.

Summary of the invention the utility model provides mainly that a kind of processing technology is simple, the inner container of electric water heater of long service life.The utility model is to establish corresponding with its inner surface configuration size in the steel inner container of electric water heater and with the whole covering of steel inner container inner surface and the plastic inner lining closely of fitting, itself and steel inner container composition combined type inner bag.Above-mentioned liner is to be made by heat-resisting nontoxic plastics, and it can allow for a long time to work in temperature is 100 ℃ environment.This liner can be an individual layer, also can be the multilayer superposition together.The connected mode of above-mentioned liner and steel inner container has multiple, and as plastic inner lining rotation molding in steel inner container, then both natural combination together; As liner is to give the integral body that makes, and then the two halves steel inner container is enclosed within its outside, constitutes whole inner bag by the securing member butt joint then, and this moment, liner was close on the steel inner container.

The utility model has following advantage compared to existing technology: 1. and simple in structure, processing and manufacturing easily, cost is low.

2. can effectively water and steel inner container be isolated, make it not to be subjected to corrode, prolong the service life of inner bag.
