Problems solved by technology
The surface of the ordinary electric heating tube is relatively rough, not smooth and looks unattractive. After a period of use, scale is prone to appear on the surface of the electric heating tube, which affects the heating efficiency and service life of the electric heating tube.
In order to solve the problems of ordinary electric heating tubes, some companies currently enamel the surface of electric heating tubes, but the enamel also has the disadvantage of being fragile, and hot and cold water exchanges are often encountered during the use of the heater. , the surface of the electric heating tube is prone to cracks, and scales are still prone to appear after the cracks appear, which will affect the heating efficiency and service life of the electric heating tube

Embodiment Construction
[0010] The specific content of the present invention will be described in detail below with reference to the drawings and specific embodiments.
[0011] Such as figure 1 , figure 2 As shown, an electric heating tube for a water heater includes: a heating tube body 1 and a heating core 2 arranged in the heating tube body 1, and a Teflon coating 3 is arranged on the outside of the heating tube body 1.
[0012] The above-mentioned electric heating tube for water heater is provided with a Teflon coating 3 on the outside of the heating tube body 1. Teflon has significant thermal stability and good resistance to high and low temperatures, generally between 240°C and 260°C It can be used continuously, can work at freezing temperature without embrittlement, and does not melt under high temperature; corrosion resistance, acid and alkali resistance, because Teflon has strong inertness, except for individual media, it can resist various acids, Alkali, salt and organic matter (solvent), Tefl...

The invention discloses a long-life electric heating pipe for a water heater. The electric heating pipe comprises a heating pipe body and a heating core arranged in the heating pipe body, wherein a polytetrafluoroethene coating is arranged on the outer side of the heating pipe body. The electric heating pipe has the advantages that the polytetrafluoroethene coating is arranged on the outer side of the heating pipe body; polytetrafluoroethene has very good heat resistance, can be continuously used in a temperature range of 240-260 DEG C, has remarkable heat stability, is corrosion-resistant, acid-resistant and alkali-resistant, and has extremely low frictional coefficient; and by applying polytetrafluoroethene to the outer side of the heating pipe body, the heating pipe is smoother and more attractive in surface, good in flexibility and unbreakable, cracks do not occur on the surface of the heating pipe, and water scales difficultly occur on the surface of the electric heating pipe, so that the heating efficiency and the service life of the electric heating pipe are ensured.
Description
Technical field [0001] The invention relates to a heating device, in particular to an electric heating pipe for a water heater. Background technique [0002] Water heater is a device used to heat water, and its application is very wide. There are also many types of water heaters on the market. The core component of the water heater is an electric heating tube set inside it. The structure of a common electric heating tube includes: a heating tube body and a heating core set in the heating tube body. The surface of the ordinary electric heating tube is relatively rough, and it is not smooth and looks unsightly. After a period of use, scale will easily appear on the surface of the electric heating tube, which affects the heating efficiency and service life of the electric heating tube. In order to solve the problem of the storage of ordinary electric heating pipes, some companies currently apply enamel on the surface of the electric heating pipe, but the enamel also has the shortco...
