Abstract
The utility model discloses a water heater electric heating device having a ceramic or glass coating. An electric heating tube of the electric heating device is coated with the ceramic or glass coating. The electric hearting tube of the water heater includes an electric heating tube, a temperature measuring tube and a flange. The electric heating tube, the temperature measuring tube and the flange are welded integrally. The electric heating tube is coated with the ceramic or glass coating. The coating effectively prevents the corrosion of the electric heating tube. And the coating also has a function of resisting scaling. The coating has a function of prolonging service lives of the electric heater and the water heater. The thickness of the coating is smaller than 100 micrometers. The coating is so thin that nearly no influence is generated on heat transmission speed when the coating covers on the surface of the electric heating tube. And since the coating belongs to inorganic substance of ceramics or glass, the coating has excellent performance in adhering to a base material, is not easy to craze or peel off, and can endure short-term dry heating. The above capacities of the coating in the utility model are obviously better than a prior enamel coating and a prior organic non-stick coating.
Description
Technical field
The utility model relates to the electric heater of water heater, more particularly, relates to a kind of water heater electric heater with performance pottery or glass coating.
Background technology
The electric heating water heater is the essential product of people's daily life, and its safety and reliability are extremely important.Because the environment for use very severe of electrothermal tube, long period of soaking is in having the water of temperature, along with the passing of service time; The fouling of the whole electrothermal tube of generation easily; The electrothermal tube corrosion waits corrosion phenomenon, and this phenomenon can shorten electrothermal tube useful life significantly; Electrothermal tube corrosion fracture can take place under the serious situation, major safety risks such as electric leakage.
The existing strengths and weaknesses analysis that prevents the electrothermal tube corroding method:
1), the Teflon spray process is carried out on the surface: this processing is to the organic non-sticking lining of electrothermal tube surface coverage one deck, and the not viscosity of non-sticking lining can solve the scale formation of electrothermal tube use effectively.But non-sticking lining belongs to organic coating, can't bear high temperature, and (when the water heater accident is cut off the water supply dry combustion method) all can thoroughly be destroyed coating performance when any once unexpected high temperature, also can produce toxic and harmful simultaneously; Non-sticking lining hardness is not high, easily in assembling process because slight damaged in collision coating makes base material expose; There is tiny micropore in the existing in addition non-sticking lining, contacting of exclusion of water and electric heating tube base material fully, these phenomenons make non-sticking lining can not prevent the aqueous corrosion phenomenon of base material long period of soaking in water fully.
2), enamel processing is carried out on the electrothermal tube surface: this processing is to cover one deck enamel coating to electrothermal tube surface and perishable position; Through contacting of isolated electric heating tube base material of enamel coating and water; Can improve the corrosion resistance of electrothermal tube, general specification enamel coating THICKNESS CONTROL is 0.15 millimeter-0.5 millimeter (150-500 micron) scope now; But because the limitation of construction technology can't be avoided the thinner or thicker phenomenon of enamel coating.Can't form effective enamel protective layer if coating is too thin; If enamel layer is too thick, coating cracking burst porcelain phenomenon will very easily take place, the coating burst porcelain position that comes off becomes the perishable position of electrothermal tube again, and the corrosion resistance that the enamel electrothermal tube that enamel layer peels off occurs will reduce greatly.Also have because enamel layer thickness is thicker, when electrothermal tube was worked, heat was owing to receive the obstruct of thicker enamel coating, and radiating rate is affected; Also have because the restriction of enamel processing technology (existing employing slurry dip-coating mostly or the electrostatic dusting that dusts processing); All there is bigger difference in thickness in instant enamel coating thickness on same workpiece, can't avoid owing to the too thick coating burst porcelain phenomenon that takes place of local coating once in a while; And the formation of enamel coating need be accomplished under the above high-temperature condition of 800 degree, and energy consumption is bigger.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective of the prior art, and a kind of electrothermal tube corrosion and scaling of effectively preventing is provided, and can prolong the water heater water heater electric heater with pottery or glass coating in useful life effectively.
For realizing above-mentioned purpose; The technical scheme that the utility model provides is following: a kind of water heater electric heater with pottery or glass coating is provided; Comprise electrothermal tube, temperature tube, flange; Said electrothermal tube, temperature tube and flange are welded as a whole, and scribble the coating of performance pottery or glass on the said electrothermal tube.
The described beneficial effect with water heater electric heater of pottery or glass coating of the utility model is: this coating has in the high strength and the high rigidity performance of pottery and glass; Combine fine and close with the electrothermal tube base material; Contacting of isolated electrothermal tube base material and heat medium, thereby the corrosion resistance of raising electrothermal tube; The color of this coating can be made with gloss and be similar to pottery or the same outward appearance of glass, also can be other colour generations and outward appearance.
In above-mentioned pottery or glass, add not sticking element; Make the pottery or the glass coating that form have not viscosity; This coating have simultaneously preventing scale deposite and with the base material corrosion proof function; Make electrothermal tube have self corrosion resistance and the long-time preventing scale deposite property of using simultaneously, with performance that greatly improves electrothermal tube and useful life; Coating layer thickness generally is significantly less than 100 microns; Because coating layer thickness is thin, covers the electrothermal tube surface and hardly heat transfer rate is exerted an influence; Excellent with the tack of base material, be not easy cracking and peel off; These performances obviously are superior to existing enamel coating.
The coating material is made up of inorganic matter, and coating hardness and intensity are fine, holds out against the collision and the scraping of water heater assembling process, also can bear to be similar to water heater because unexpected dry combustion method phenomenon of the short time of cutting off the water supply; These performances obviously are superior to the organic coating of existing teflon non-stick application processing; And coating be as long as just can form (being starkly lower than the enamel processing temperature) under the baking of lower temperature, and the production of the course of processing is consumed energy and obviously is less than enamel technology.
Below in conjunction with accompanying drawing and embodiment the described water heater electric heater with pottery or glass coating of the utility model is described further.

Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below be the said preferred example of the utility model, therefore do not limit the protection range of the utility model with water heater electric heater of pottery or glass coating.
With reference to Fig. 1, Fig. 2; A kind of water heater electric heater with pottery or glass coating is provided, comprises electrothermal tube 1, flange 2, temperature tube 4; Said electrothermal tube 1 temperature tube 4 is welded as a whole with flange 2; Scribble the coating 3 of pottery or glass on the said electrothermal tube 1, coating 3 has and prevents electrothermal tube base material corrosion function, also can have the preventing scale deposite function simultaneously.With performance that greatly improves electrothermal tube 1 and useful life.
