CN202634732U - A water and electricity separation electric heating metal tube - Google Patents

Abstract

A water-electricity separation electric heating metal pipe, the outer wall of the metal pipe body 1 is wrapped with a high temperature resistant insulating layer 2, and a heating metal body 3 made of a special alloy material is spirally evenly wound on the outer wall of the metal pipe body 1 that has been insulated, and the outer layer of the heating metal body 3 is also plated with an insulating and flame-retardant insulating layer 4. Due to the use of double insulation protection, the product completely separates the water flow and the electric heating function, avoids the terrible consequences of electricity in the water, and greatly improves the safety performance of the water heater. The heating speed is fast and the efficiency is high, no water storage tank is required, there is no scale trouble, and the effect of environmental protection and energy saving is achieved. It is easy to process, install and maintain, and provides convenience for the miniaturization of water heaters.

Description

A water and electricity separation electric heating metal tube

technical field

The utility model relates to the field of sanitary baths, in particular to a water and electricity separation electric heating metal tube.

technical background

At present, the electric heating metal pipes on the market are mainly used in water heaters with water storage tanks. The electric heating metal pipes are in direct contact with the water, and the inside of the water storage tanks is prone to scale and corrosion, resulting in leakage of electricity, resulting in terrible consequences of electrification in the water, and low safety performance. , short service life. The water heater with the water storage tank has a large volume, and it is impossible to reduce the volume of the water heater under the same power output, which saves materials and reduces the use of space, which hinders the development of the water heater to miniaturization.

Contents of the invention

The purpose of the utility model is to provide a water and electricity separation type electric heating metal tube, which is mainly used to improve the safety of the water heater during use. It does not need a water storage tank, can be heated immediately when it is turned on, is more energy-saving, saves materials and space, and develops towards miniaturization of the water heater. to offer comfort.

In order to achieve the above object, the utility model adopts the following technical solutions:

A water and electricity separation electric heating metal tube, including a metal tube body 1, characterized in that the outer wall of the metal tube body 1 is wrapped with a high temperature resistant insulating layer 2, and the electrified heating metal body 3 is wrapped on the outer wall of the metal tube body 1 that has been insulated.

The electrified heating metal body 3 is a heating wire wound on the outer wall of the metal pipe body 1 that has been insulated.

The outer layer of the energized heating metal body 3 is also coated with a heat-resistant and flame-retardant insulating layer 4 .

Adopting the above-mentioned technical scheme, the water flow and the electric heating function of the product are completely separated, which greatly improves the safety performance of the water heater. The heating speed is fast and the efficiency is high. There is no need for a water storage tank, and there is no scale trouble, which saves materials and reduces the use of space. Processing , Installation and maintenance are convenient, and it provides convenience for the development of water heaters to miniaturization.
